Knowledge Management Techniques - Essay Example This research will begin with the definition of knowledge management as the tools, techniques and strategies to retain, analyse, organise, improve and share business expertise. This definition of knowledge management seems incomplete for the reasons mentioned in the following discussion. The definition restricts knowledge management to the business sector only, whereas in my view knowledge management engulfs almost all the real world issues. However the generalization indicated through the terms â€Å"tools†, â€Å"techniques† and â€Å"strategies† makes this sound more appropriate. In practice knowledge management cannot be defined or expressed through specific terminologies. This is because the current meanings associated with the modern tools and gadgets may not be able to cope up with the growing pace of the phenomenon that drives knowledge management. To me the span of knowledge management is ever expanding. The endless limits of data generation and spread o f knowledge owing mainly to globalization are just a few of the factors that contribute to this paradigm of thought. Knowledge management is the effective learning processes associated with exploration, exploitation and sharing of human knowledge (tacit and explicit) that use appropriate technology and cultural environments to enhance an organisation’s intellectual capital performance. The definition explains knowledge management as a combination of processes that are performed on knowledge. These processes are â€Å"exploration†, â€Å"exploitation† and â€Å"sharing†. ... With this description the ever growing meanings of knowledge management cannot be justified. This definition categorically covers the aspects related to technology and cultural environments. The main purpose of the whole exercise indicated in this definition is to improve the organization’s working in terms of intellect. The most useful characteristic narrated in this definition is â€Å"effective learning†. For learning to be effective it needs some scope or domain in which it can be exercised. Generally there is no such thing as ineffective learning. The definition highlights the relevance learning and its respective domain. Definition 3: â€Å"Knowledge – the insights, understandings, and practical know-how that we all possess – is the fundamental resource that allows us to function intelligently. Over time, considerable knowledge is also transformed to other manifestations – such as books, technology, practices, and traditions, - within organis ations of all kinds and in society in general. These transformations result in cumulated expertise and, when used appropriately, increased effectiveness.† (Wiig, 1993) Evaluation: The definition proclaims that the basic entity that works behind intelligence is knowledge. This declaration may refer to the logical exploitation of knowledge as â€Å"intelligence†. Seemingly the words may hold broader sense than expected. The term â€Å"traditions† takes this definition very close to the real life phenomena. The assertion can be seen through the usage of term like â€Å"society†. Books, technology, practices and traditions are considered as varieties of appearances of knowledge. In my view these may also be considered as means or medium of knowledge transfer and usage. Knowledge encompasses both i.e. individual and

Robin Hood Case Analysis Essay Example for Free

Robin Hood Case Analysis Essay Robin Hood Case Analysis BY JAZZY08 In the Robin Hood case, we can easily apply the principles of a business organization. Robin was the CEO of the Merrymen. He made all important decisions and a few lieutenants serve in roles that have been delegated such as information gathering, discipline, finances and provisioning. These make up the top management in the organization. This is associated with the Fayolism theory developed by Henri Fayol who proposed that managers perform particular functions for the growth and success of the organization. The four tasks that have been delegated as well as Robin Hoods personal vendetta against the Sheriff serve as the basis for many problems encountered by the Merrymen. First year, did well because they were a small organization experiencing little problems, growth was steady, revenues were consistent due to stealing from the rich, no major competitive forces were established in the industry and Robin Hood and the Merry men had the support of the stakeholders (peasants and farmers) because the men saw to it that the people were taken care of as well as their equal hate for the Sheriff . According to Henri Mintzberg what is expected of a manager is described through management roles. Robin as the CEO possesses the decisional roles which entails the important decision making and choices. The Merrymen acquire informational roles through information gathering and finances as a few of their delegated tasks and finally, the peasants and farmers possess the interpersonal skills that are very symbolic in nature because of their absolute interest and support in the efforts made by Robin and the Merrymen. Their peasants and farmers are the main reason for their formation rob the rich-give to the poor). Over the years, Robin Hood was faced with many issues that needs to be addressed. He believed that the strength and manpower of any army was in its numbers and so the band is growing too large with insufficient resources to sustain it. There is also a decline in the Merrymens vigilance as it is so hard to keep track with the larger numbers which may cause them to be unprepared if the Sheriff were to place a surprise attack on them and discipline is hard to enforce resulting in less control. This issue needs to be resolved in order for the men to work well with one another before a case of mutiny outbreaks (Robert. L. Katz; human skills). The Sheriff is growing stronger and becoming better organized because of his owerful allies as well as the support of the evil Prince John. Just as the numbers of Merrymen are growing, travelers are beginning to find alternate routes through the forest to avoid apprehension, causing a decline in the bands revenue stream. This is the major problem that Robin Hood needs to overcome. If he cannot steal the rich peoples money, he has nothing to give to the poor which can cause a strain in the relationship with his stakeholders. Also, with no money, Mr. Hood will not be able to maintain his group of Merrymen, and they will become weaker making themselves susceptible to attacks from the Sheriff. The two satellite problems facing Robin Hood are the intensive threat of competitive rivals and threats to suppliers. The core problem is rivalry, Prince John and the Sherriff are Robins main rivals and pose a definite threat to his operation. They are in direct competition with each other, and their actions have to constantly be monitored which is going to be difficult due to the their persistent efforts to capture Robin Hood and his Merrymen. Suppliers are a high level threat, because at any point those who support Robin Hood could be captured by Prince John and the Sherriff, thus cutting off supplies. Also, the bargaining power of suppliers is high simply because of the business Robin is involved in(robbing). His business is illegal and therefore a high level threat to anyone who supplies to him. Threat from buyers is currently a low level threat because an objective of Robins is to give to the poor. They have no reason to pose any threat unless at some time Robin Hood begins to tax them. The threat of new entry is also low given the legality of this endeavor. Individuals will likely be more willing to Join Robin Hood as opposed to forming their own faction. Although it is bviously more common to have a threat of new entry when in control of the market while making a profit, in this particular situation it is relatively low given Robin Hoods rapport within the forest. The threat of substitute products has been identified as a low to moderate threat. The residents of the forest are assumed to be the customers. The variable that make them a threat include: the perceived possibility that Robin may fail. In the event of this transpiring, the most probable alternative would be the majority of the people leaving the forest. This is a low to moderate threat because lthough Robins current status is relatively stable; his customers face the real possibility of being forced into making alternative decisions. This, along with the changes in the external environment is making the bands business model obsolete. These changes must be addressed along with the structuring and training of the ever-growing band of Merrymen. In short, Robin needs to select a new strategy and rally the Merrymen behind the cause because the current strategy is becoming timeworn at a hurried pace. Robin Hood and his men need a new mission, objectives, and strategy. Their vision is belonging to a kingdom with an honourable King who treats everyone fairly. His new mission should be to free the people from Prince John and return King Richard to the throne. Robin Hood and his band are in need of a fresh strategy in response to external happenings. For instance in the situation where the travelers are beginning to avoid the forest, despite added cost and inconvenience, to protect their belongings. Also, Robins plan to force the Sheriff out of Nottingham by causing unrest is not working. Indeed, the Sheriff is using powerful connections to apply added pressure to Robin and the Merrymen. To further complicate matters, some of the barons that appointed Prince John to the throne are now campaigning to clandestinely raise the ransom to free King Richard. These barons have offered Robin Hood the chance to help in this mission in exchange for future amnesty. While the return of King Richard and the ousting of Prince John is what Robin wants, the risks involved in such a deal are very high. The mission of the gang is rob from the rich and give to the poor. However, the true goal of the organization is to remove the amoral Sheriff from office, as evidenced by the consideration of Robin to institute a fixed transit tax. A more appropriate mission would be rid Nottingham of the corrupt King John and Sheriff. The gang also needs to outline some objectives, as this has not been done in the past. For example, each Merryman shall produce enough loot each day to pay for his own food. The band does need a new organizational structure as a result of the lead for change in structure would possibly be promoting more lieutenants in order to monitor the men more effectively and keep the men clear of their strategy. Maybe the group could form smaller camps that are part of the whole for organizational stability and spread across the entire forest of Nottingham. Robin Hood could Join with the barons to collect the ransom to release King Richard, receive amnesty and a resolution to the campaign against the Sheriff. It is risky because the barons could offset his efforts and if the plan proves to be unsuccessful, Prince John will unleash his vicious and volatile side to ensure Robin Hoods demise, but it is less risky than doing what he is presently doing which is nothing. In assisting them, he has more support against the Sheriff. If he continues to do nothing he will eventually end up caught by the sheriff, run out of supplies or mutiny will break out among his men. Robin Hood must weigh the benefits and risks of the following : forming a strategic alliance with the barons to rescue King Richard , expanding the organization into areas outside Sherwood Forest ,killing the Sheriff as a defensive strategic move or switching to a fixed transit tax as an offensive strategy move. A SWOT analysis will help determine some strategic alternatives and how the band can attempt to fulfill its mission and achieve its goals. Robin Hood can use the SWOT analysis to identify where he is strong and vulnerable, where he should defend and attack by scanning both internal and external environments. The group has grown spontaneously in its numbers. Manpower is the largest resource any group can have and the number of the Merrymen is formidable. Robin Hood is also a strong leader. For any one-single man to organize a group of this caliber, strong leadership skills must be present. The brand recognition the Merrymen posses has also been a strength. Because the group is so popular, it has allowed them to make a difference in their community. This popularity has also gained the group access to the resources of the surrounding towns and communities. The cost of training and producing their product is also a trength as well as their skills of being well trained fghting men. According to Robert. L. Katz, managers need three essential skills, in being well trained men, they must acquire Job- specific knowledge and technigues needed to proficiently perform work tasks (technical skills) They simply steal to obtain the capital they need and training costs are small outside the capital needed to supply the arms and feed the Merrymen. Most of the combat supplies are probably stolen as well. Moreover, new recruits are coming in and the men are being reunited in the enmity against the Sheriff. The first major weakness I have identified is Robin Hoods personal grudge with the sheriff. This has a great potential to cloud his overall view and influence judgments that may otherwise may not be for the good of the group. Even though the group was born from this idea, it has seemingly surpassed Just over-throwing the sheriff and transformed to a scope much larger. This personal vendetta may not take this into account and cause ill-formed decisions. The second major weakness I have identified is the alliances Robin Hood has made. This problem encompasses a few of the other weaknesses the Merrymen have. At first, the recruitment looked for viable candidates that fit a certain criteria. Now, the Merrymen will accept anyone who is willing to serve the cause hence there is a lack in familiarity with all the organizational members. Because of this single change in recruitment procedures, the now laxed recruitment process, another issue has arisen; exceeding the food capacity of the surrounding lands. This is simply a numerical problem that is encountered when you let anyone Join a group that relies so heavily on natural resources. The food shortage has also resulted in a depletion of the Merrymens financial reserves. Since the land can no longer provide the resources the group needs, they have turned to trade and purchasing. The large number of the group has also caused a space problem. The next major sets of weaknesses I have identified are a result of the looting and raids the Merrymen participate in. This raised the question to Robin Hood of what alternatives are available to help the group raise funds. Robin Hood favored taxation of the travelers and local towns people rather than looting and raiding but this concept was met with much resistance. His lower management argued that taxation would turn their closest allies against them and ould virtually put them in the same category as the Sheriff. A major opportunity present that is not coupled with the weaknesses the Merrymen have is the proposition of freeing King Richard. Securing the release of King Richard, if successful, would be very beneficial to the Merrymen. This is potentially another source of income for the Merrymen and would shine beneficial political light on the group. If the group were to fail, the retribution would be detrimental. Instead of fghting Just one sheriff and his men, the band would potentially have to take on the entire army commanded by Prince John. The opportunities present are forming an alliance with the barons in order to bring King Richard back to Nottingham and expanding the Merryman into the forest spreading revenue base. The sheriff, of course, was the source of the major threats to the Merrymen. At first the campaign was successful but over time the sheriff and his forces are growing larger and better organized causing increased direct competition. They have received the funding they need to disrupt the Merrymens operations. The plan the group first used forecasted that a perpetual state of unrest would cause the Sheriff to be removed from his osition, however the opposite happened and the sheriff used the unrest to secure reinforcements and funding for the campaign. This was a result of his close strategic alliance with Prince John. Moreover, Prince John is very paranoid and could act irrationally by sending his spies to offset the Merrymen. Additionally, aligning with the barons is very risky as they could deceive Robin. Several recommendations have been developed for the Merrymen to aid in the success of the group. It is the belief that the current strategy is one that can again be successful but many changes need o be implemented to ensure this strategys success. I recommend that Robin Hood align with the barons. He should help them collect the ransom that would free King Richard. In order for this to work, Robin Hood would have to sell this idea to the Merrymen and the farmers and the townspeople and change the policy of outright confiscation of goods. He has to convince them that the fixed transit tax will go towards their Kings ransom. Robin acquires the conceptual skills required of any manager to perform proficiently according to Katz, he is looking at the bigger picture which he believes everyone will benefit from. conceptual skills). This will help everyone feel loyal and patriotic to one common cause. The citizens already do not like the Prince John and they would likely unite together and support any strategy lieutenants to help the already overworked ones that he has, given the state of discipline and other problems. Robin has considered killing the Sheriff but it would not end the campaign because it has grown beyond the scope of Just the Sheriff, but decided against it because it would only satisfy his thirst for revenge without improving the matter. The next Sheriff would undoubtedly be Just as bad if not worse ecause the Sheriffs association is devoid of values. Also, with the Sheriffs high- powered friends and increasing resources, the chances of succeeding in the slaying are dim because this would more than likely anger Prince John into dealing out very harsh punishment that could terminate Robin Hood and his men. If there is an unsuccessful attempt on the life of the Sheriff, retribution will be fierce. The Merrymen need to build off the strengths it has. The quality of the manpower is an area of concern. Implementation of the original recruitment process or an advanced recruitment process is the first necessary fix. Just letting anyone be a participant of the group has been the source to several of the issues plaguing the Merrymen. Candidates should have a particular set of skills to allow entry. If there is a food shortage, pre-screen candidates for skills such as farming. Discipline has been identified as another issue. This can be eliminated through the better screening process and better training. For this all to work, there must be a better management system put in place. The external threats, weaknesses and opportunities the Merrymen have are formidable but proper action can be used to manage these. The ack of food and provisions can first be solved by recruiting farmers and hunter/ gathers to the group who solely focus on these issues as well as enforcing that the men produce enough loot each day for his own food. This would also help eliminate the expenses the group incurs as trading and bartering for provision could be gradually eliminated. Since revenues are in decline, any money-saving action is beneficial. Concurrent with this issue, expansion of the raiding area is a must. Though Robin feels as though he is losing control of the band, he admits to not knowing half of the men and is finding it hard to enforce discipline. They have the opportunity of limiting the size of the band which maintains discipline and solves food scarcity which basically curtails growth. This strategic move will deem them weak and powerless against the Sheriff and Prince John. The more manpower they have, the greater chance they have of carrying out the mission. The band should extend their operations throughout Sherwood Forest in order to rejuvenate revenues, which at present are in decline. They may also be able to access supplies more readily which previously would have been obtained from outlying villages, thus reducing costs. This also allows them the opportunity to continue robbing in an adjacent region which is consistent with the original organization and its growing size. The part of the group that conducts raids should also work very closely with the intelligence gathering portion. Once again, proper recruitment and training will result in a part of the group who can focus on this important aspect. The intelligence can be used to know when and where raids are conducted and what moves the sheriff is making. However, all the groups need to be properly trained in combat for when the need arises. These groups should continue to be managed separately.. In this instance, time is of the essence. As the Sheriff of Nottingham and his men learn Sherwood Forests resources have been depleted by the large amounts of recruits that inhabit the area, and this has seriously drained the bands financial reserves, however, this does give the men a greater asset in their numbers. The case seems unclear about where the Merrymen see themselves over the next few years, but one thing is clear, if they wish to survive, they will have to take immediate action. If the band is successful overthrowing Prince John, they will have to work in close onjunction with King Richard to shape a society which functions equally for members of all socio-economic classes (assuming this is their goal). The central issue faced by Robin Hood and his Merrymen is how to win their fght against the Sheriff of Nottingham. We recommend partaking in this venture though because we see the benefits outweighing the risks. However, this must be a carefully planned and executed venture. Robin Hood and his band should organize an attack on Prince John in order to eliminate the Sheriffs authority over Nottingham and its occupants. If successful, the Merrymen will return to their law abiding life.

National Political Influence and the Catholic Church Essay -- Politics

Democratic transitions recently became a topic of great discussion among political scholars as a domino effect of democratization began in Latin America in the 1970s and continued through Eastern Europe in the late 1980s. In many of these transitions, the Catholic Church[1] played a crucial role as the protector of civil society during periods of communist and right-wing authoritarian rule, as well as taking an active role to promote the establishment of democracy (Bruneau 1994, Levine 1980, Stepan and Linz 1996, Perà ©z-Dà ­az 1993, Ramet 1987). While the Church’s political role in transition is important, significantly fewer scholars have explored how democracy affected the Catholic Church within the national context (Eberts 1998, Ramet 1999, Vilarino and Tizon 1998). Even fewer have attempted cross-national comparisons of the Church, thus permitting generalizations to be made about the political influence of the Church since the institution of democratic governance (Casan ova 1993, Gill et al.1998). With the establishment of democracy the Church was expected to flourish, due to its organizational and political advantage within new democracies. However, initial research suggests otherwise. Using the involvement of the Church in abortion policy as an indicator of political influence, it is clear the cases of Spain, Brazil and Poland vary extensively. The Polish Church maintained the most political influence, followed by the Brazilian and Spanish Churches (Neilsen 1991, Volenski and Gryzmala-Mosczynska 1997, Gautier 1998, Casanova 1993, Linz 1991, Morris 1993). In Brazil and Poland, the Church played an instrumental role in the democratic revolution, making a political decline in the Church almost inconceivable. While initially th... ...ee is regarded as a non-member state permanent observer allowing it to occasionally participate in General Assembly discussions and decisions and participate in UN International Conferences. Holy See, however, has no voting rights. [3] Secularization refers to the number of clergy that disaffiliated from the Church (i.e. transfer from ecclesiastical to civil). [4] Vatican II theology â€Å"stressed a very different notion of the Church as the people of God, assigned a more important role to the laity, redefined the authority of the Pope over the hole Church and the bishops over the diocese† (Mainwaring 1986). Vatican II theology stressed the need for social justice and vowed to help the less fortunate, this came to be known as the option for the poor. [5] The Roman Curia is the collection of ministries for governing the International Church (Della Cava 1993).

How does the family argument in Act 3 Scene 5 add to the dramatic tension in the play? Essay

Romeo and Juliet is a tale of two star-crossed lovers written by William Shakespeare. Throughout the play Shakespeare successfully maintains the audiences attention and interest by creating a large amount of dramatic tension. The family argument in act 3 scene 5 could possibly have a bigger effect on the audience than other parts of the play. Thisis a play about star-crossed lovers who’s forbidden love led to their horrific death. Act 3 scene 5 presents a substantial turning point in the play. Shakespeare introduces the audience to the majority of the lead characters and also shows the audience the hatred and feud between the Capulet’s and the Montague’s. This feud does have an impact on the relationship between Romeo and Juliet. Both Romeo and Juliet belong, to one side of the feuding families, Romeo to the Montague’s and Juliet to the Capulet’s. The Montague’s and the Capulet’s feuding was the whole reason for the tragedy. They should have reconciled their differences years ago, if they had done this, maybe there children’s life’s wouldn’t have been taken. The hatred goes a while back, In the Prologue to Romeo and Juliet, the Chorus tells us of an â€Å"ancient grudge† between two households of equal dignity†. This states that the hatred between them is ancient, meaning a long time ago. It also says that both families are of equal dignity, meaning not one family is more wealthier than the other, or has a bigger house, or more land they are the same. In the 16th century it was normal for girls of a mere age of 14 such as Juliet to get married, or to have an arranged marriage, and to be very obedient to her parents. Also in high society, children were often raised by a ‘wet nurse’ and did not have a strong bond with parents. This we can see is an obvious link to Juliet and her Nurse, Juliet has a stronger bond to her Nurse, than to her own mother, as we get to see later on in the play. The father was the undisputed head of the household, which Lord Capulet and Lord Montague are. Another point is a strong belief that the slightest wrong or insult must be avenged as a matter of personal pride or to protect reputation, as this again links to the two feuding families, which could link to death again another obvious link to the play, the two families lead to there children death by arguing all the time. Shakespeare was known to put themes through out his plays, Romeo and Juliet plays part to many themes and they all have a significant role in the story. Including love at first sight this was command in the 16th century if you do not fall in love when you first set eyes on each if you that that there is an immediate connection, this is classed as true love. Another theme is Hate, representing the two feuding families the Capulet’s and the Montague’s. Fate was another belief, was that your future was mapped out for you in the stars, and that you couldn’t influence your future; it’s just like reading our horoscopes really. And Loyalty some characters have certain loyalties such as the Nurse and Juliet, Friar and Romeo, as the story moves on these loyalties become hard to maintain. At the beginning of the play in Act 1 Scene 2 Lord Capulet has very different views at the beginning of the play, which contrast the later views, about marriage. In this scene as he is talking to Paris, and as Paris is asking for a proposal to Juliet. Lord Capulet’s views are â€Å" Let two more summers wither in there pride. Ere we may think her ripe to be a bride†. He is saying that Juliet is to young for marriage, and telling Paris to wait two more years and then she may be his bride. â€Å" She’s the hopeful lady of my Earth†, he is saying that Juliet means the world to him, and that he couldn’t live without her. But Capulet does something that Fathers aren’t supposed to do in this time period, which is â€Å" And she agreed, within her scope of choice, lays my consent and fair according voice†. Lord Capulet is willing to let Juliet to make her mind up about Paris, and his consent is up to Juliet’s choice. This shows that Lord Capulet is leaning towards Juliet’s views here, which shows that he cares for his daughter and that he is not forcing her into marriage, just proposing the idea. We pick up the talk about marriage again in the middle of Act 3 Scene 5 where Juliet and her Mother Lady Capulet are deep in conversation. â€Å" One who, to put thee from thy heaviness, Hath sorted out a sudden day of joy† She is saying that Juliet’s father has put out a sudden day of joy. â€Å" Marry my child, early next Thursday morn†¦shall make thee a joyful a bride†. As an audience we react these couple of lines as how can she marry to the County Paris, if she is already married to Romeo? This is called dramatic irony when the audience knows more than the characters. So Lord Capulet has totally changed his mid bout marriage, before he says saying Paris you will have to wait two more years but now he has changed it to Thursday only four days away. Then Juliet responds â€Å" †¦ He shall not make me there a joyful bride†¦I wonder at this haste, that I must wed†¦Ã¢â‚¬ Ere he that should be husband comes to woo†. Juliet is astonished at why she has got to marry so fast, and she’s saying well shouldn’t he come and win my heart and get to know me before I accept? â€Å" It shall be Romeo, whom you know I hate, Rather than Paris. These are news indeed†. Even though Juliet is saying that she would rather get married to Romeo, we know that she all ready is, and that she doesn’t hate him at all, she loves him. Then Lord Capulet and the Nurse enter the room â€Å" How now, a conduit girl? What, still in tears? Lord Capulet is being a concerned, caring and affectionate father now, but this soon changes. As Lord Capulet asks his wife about how as she taken the news, Lady Capulet says she no but says thank you. Juliet speaks â€Å" Not proud you have, but thankful that you have†. à ¢â‚¬Å" But thankful even for the hate that is meant love†. Then Lord Capulet answers how dare you disobey me, spoilt brat, if you don’t go I will drag you there myself. He even calls her a â€Å"sickness-carrions meaning rotten meat, baggage, and tallow face meaning pale face. This is a total turn around from how understanding, caring he was a couple of seconds ago, and how he was saying to Paris â€Å" She’s my hopeful lady of my earth†. Now it has changed to rotten meat! Then Lord Capulet gets really angry â€Å"Hang thee, young baggage, disobedient wretch† Get yourself to the church on Thursday or never speak to me again. â€Å" My fingers itch† now he is so angry that he wants to hit her. And that she was a curse to have! The audience would probably feel sympathetic to Juliet now, because its not just that she doesn’t want to marry Paris it is the fact that she is already married, to Romeo. As this scene continues Lord Capulet is fuming with Juliet, as this scene is vital for the dramatic implications to the rest of the play. Nearing the end of this feud Juliet shouts â€Å". Or if you do not, make the bridal bed, in the dim monument where Tybalt lies†. Here Juliet is foreshadowing the future, because infact she does die. Lady Capulet then says â€Å" Talk to me not, for ill not speak a word†¦ I have done with thee†. At this moment in time, not only her father has left her, so has her mother. So then Juliet turns for to the Nurse for some advice. But the nurse’s advice is to forget about Romeo and just to marry Paris. I think that the Nurse might just be saying this because she played a role in the marriage of Romeo and Juliet so she is frightened that she might be discovered. So even though there are many loyalties through out the play, which seem to be genuine, would someone break the trust, just to save himself or herself? â€Å" Marry, I will, and this is wisely don’t† says the nurse, so the Nurse thinks that Juliet has taken her advice thinking that she is complaint and obedient. But then Juliet says â€Å" If all else fail, myself have the power to die†, this is also dramatic tension because this conversation has now brought Juliet to think about killing herself, so she doesn’t have to marry Paris. Juliet increasingly feels trapped. So she is so desperate that if the Friar won’t help herm then she sets about making the plans that will lead to her tragedy. Her father has threatened her, her mother has abandoned her, and she feels like the nurse has proved a false friend, as the nurse has always been like a Mother to her, I think that the Nurse letting her down affects her more than her own Mother letting her down. In conclusion, at the start of the play in the prologue we already know that two â€Å"star crossed lovers† are going to take their life. The term in meaning star crossed suggests that their paths were never meant to intertwine with each other and if they did it would only result in tragedy. This main argument did contribute dramatically to the final tragedy, which was Juliet taken her own life, Romeo also taking his own life. So in my opinion the two families were to blame, if they didn’t constantly hate each other maybe their children wouldn’t have dies just to be with each other.

DBQ-The Witch Craze

Identify and analyze at least three major reasons for the persecution of individuals as witches in Europe from the late fifteenth through the seventeenth centuries. From the Middle Ages until the 1700s, a fevered witch craze was spread throughout Europe. These witches were isolated, persecuted and when found, tortured and consequently killed. With most of the population concentrated in southeastern Europe, over 100,000 witches were tried.It was believed that these individuals practiced black magic and were associated with the Devil, but a single fact becomes clear when studying the witch craze and that is that there is a certain type of individual that was singled out as a witch. The majority of of accused witches were female(Witchcraft Statistics, doc 2) and mostly over 50 years old(Witchcraft Statistics doc 3). The witch craze concentrated on elderly women who more often than not were from a low social class (Witchcraft Statistics, doc 1. ).A combination of religious beliefs, socia l prejudices and cultural precepts helped heighten the already rampant witch persecution throughout Europe. The witch craze spread throughout the common-people of Europe, this due to a strong support to the persecution of witches advertised by influential religious leaders. Although Europe was in a state of religious turmoil due to the warfare between Catholic and Protestant faiths, Catholics and Protestants alike contributed to the spread of the witch craze. Martin Luther preached that â€Å"sorcerers or witches are the Devil’s whores who steal milk†¦torture babies in their cradles†¦ † (Religious Opinions, doc 3). John Calvin, another influential religious leader said â€Å"†¦ We are therefore taught by these examples that we have to wage war against an infinite number of enemies†¦ †(Religious Opinions, doc 4). Pope Innocent VII, issued â€Å"The Witch Bull† in 1484 where he stated it was the peoples duty to get rid of witches and he gave inquisitors the right to â€Å"exercise their office of inquisition and to proceed to the correction, imprisonment and punishment† of witches(Religious Opinions, doc 4).The strong religious belief that witches were instruments of the Devil and that it was society’s duty to eliminate them, along with the confusion and anger that was brought about by the Catholic-Protestant conflict was a contributing factor to the persecution and killing of many witches. While the preachings of influential leaders against the witches was a main factor of this witch craze, the fact that witches were women was an important factor within the faith.For centuries women within the Catholic church were seen as inferior to men and more susceptible to sin. Both the Protestant and Catholic leaders believed that women, specially elderly women were and easy pray for the devil’s deeds. â€Å"The Hammer of Witches† a witch-hunting manual created by Dominican monks they stated that women are more likely to be witches because they are more â€Å"credulous, impressionable and passionate†(Religious Opinions, doc 1).Once again due to the longstanding discrimination against women within the Catholic faith, the monks were probably heavily influenced by their faith which led them to speak so badly of women. The social prejudices held by European society about women made it easier for the persecutors to pinpoint them as lesser, crazy and most of all guilty. The belief that women, specially elder women were weak and inferior is an important factor to understand why they became the target group for witchcraft charges.The thought that elderly women were impure and more corrupt was spread by the lawmakers that made links between the physical body and witchcraft. A legal conference that took place in 1618 announced that â€Å"The bodies of aged persons are impure, which when they[become diseased with] malice† are used by the Devil to carry out his evil deeds( Scientific Opinions, doc1). This shows a clear societal prejudice against old people, specifically older women, but not everyone agreed there was a link between age and corruption.Belgian physician Johan Wier, while still showing disdain towards women and asserting their inferiority with their â€Å"melancholic nature and small brains†, concludes that although women were prone to depression the causes of their diseases were hardly supernatural(Scientific Opinions, doc2). Although not all society was convinced about the existence of witches, the fear and prejudice against older women was a contributing factor to the persecution of this specific group.The last, and probably greatest factor, that contributed to the fever of witchcraft was the fact that the European culture was characterized by strongly superstitious beliefs. The belief that witches could control men and do a variety of spells, is derived from the belief in the supernatural that most of the European population ha d. Thomas Ady, as describing the feelings of an English householder explains that â€Å"†¦ he cryeth out of some poor innocent neighbor that he or she hath bewitched him(Testimony of Accused Witches and Eyewitnesses, doc3).The testimony of a licensed midwife at Dillingen, Germany confessed her â€Å"witchcraft† and admitted that â€Å"she often had a good roast or an innocent child,†¦ kill young infants at birth† (Testimony of Accused Witches and Eyewitnesses, doc1). The report of Churchwardens in Gloucestershire England, reported that â€Å"†¦ Alice Prabury in our parish that useth herself suspiciously in the likelihood of a witch, taking upon her not only to help Christian people of diseases†¦ †(Testimony of Accused Witches and Eyewitnesses, doc4).All of these documents have in common the belief in evil women guided by the devil to preform witchcraft and unexplainable and horrible deeds such as eating young children, or bewitching young me n. The fact that these happenings were not only attributed to the supernatural, but where held as completely true, show the superstitious beliefs that so many held during the witch craze. These accusations were so serious that even those who were not guilty of anything ended up making delusional confessions in the midsts of torture.The beliefs were held as such truth that these innocent individuals would most likely by the end of their torture end up believing what they were charged with. â€Å"Some call me witch†¦ this they enforce upon me; and in part Make me to credit it†, cites the poem â€Å"The Witch of Edmonton†(Testimony of Accused Witches and Eyewitnesses, doc5). â€Å"Innocent have I come into prison, innocent have I been tortured, innocent must I die† wrote Johannes Junios to his daughter, clearly showing that many of these accusations were completely false(Testimony of Accused Witches and Eyewitnesses, doc 7).The combination of social prejudices , religious beliefs and cultural precepts helped spark the fire of a European witch craze that lasted over a century and claimed thousands of lives. The main target of this witchcraft were poor elderly women who were easy to dispose of due to years of hatred, superstition and discrimination. The European witch craze is a frightening example of how easily mankind is corrupted by hatred and prejudice and is lead to leave behind any sense of compassion, decency and rational thinking.While modern day â€Å"witch hunts† have been left for the movies and books to recreate, a great deal of prejudice still exists in the society we live in. The targeting of certain â€Å"weaker† groups by a â€Å"stronger† majority sadly remains a part of 21st century society. The reality of human society is that hardly anyone is willing to go through the excruciating process of admitting they are wrong, or realizing that things like gender, age, skin-color or religion are not to be used as an excuse to harm others.

The Maya Calendar

The Maya Calendar What is the Maya Calendar? The Maya, whose culture in Central America and southern Mexico peaked around 800 A.D. before going into steep decline, had an advanced calendar system that incorporated the movement of the sun, moon and planets. For the Maya, time was cyclical and repeated itself, making certain days or months lucky or unlucky for certain things, like agriculture or fertility. The Maya calendar reset in December of 2012, inspiring many to see the date as an end-of-days prophecy. The Maya Concept of Time: To the Maya, time was cyclical: it would repeat itself and certain days had characteristics. This notion of cyclical as opposed to lineal time is not unknown to us: for example, many people consider Mondays to be â€Å"bad† days and Fridays to be â€Å"good† days (unless they fall on the thirteenth of the month, in which case they are unlucky). The Maya took the concept further: although we consider months and weeks to be cyclical, but years to be lineal, they considered all time as cyclical and certain days could â€Å"return† centuries later. The Maya were aware that a solar year was roughly 365 days long and they referred to it as a â€Å"haab.† They divided a haab into 20 â€Å"months† (to the Maya, â€Å"uinal†) of 18 days each: to this was added 5 days annually for a total of 365. These five days, called â€Å"wayeb,† were added at the end of the year and were considered very unlucky. The Calendar Round: The earliest Maya Calendars (dating from the preclassic Maya era, or about 100 A.D.) are referred to as the Calendar Round. The Calendar Round was actually two calendars that overlapped one another. The first calendar was the Tzolkin cycle, which consisted of 260 days, which roughly corresponds to the time of human gestation as well as the Maya agricultural cycle. Early Mayan astronomers used the 260 day calendar to record the movements of the planets, sun and moon: it was a very sacred calendar. When used consecutively with the standard 365 day haab calendar, the two would align every 52 years. The Maya Long Count Calendar: The Maya developed another calendar, better suited for measuring longer periods of time. The Maya Long Count used only the haab or 365 day calendar. A date was given in terms of Baktuns (periods of 400 years) followed by Katuns (periods of 20 years) followed by Tuns (years) followed by Uinals (periods of 20 days) and ending with the Kins (number of days 1-19). If you added all of those numbers up, you would get the number of days that had passed since the starting point of Maya time, which was sometime between August 11 and September 8, 3114 B.C. (the exact date is subject to some debate). These dates are usually expressed as a series of numbers like so: 12.17.15.4.13 November 15, 1968, for example. Thats 12x400 years, 17x20 years, 15 years, 4x20 days plus eleven days since the beginning of Maya time. 2012 and The End of Maya Time: Baktuns - periods of 400 years - are counted on a base-13 cycle. On December 20, 2012, the Maya Long Count Date was 12.19.19.19.19. When one day was then added, the entire calendar reset to 0. The thirteenth Baktun since the beginning of Maya time therefore came to an end on December 21, 2012. This of course led to much speculation about dramatic changes: some predictions for the end of the Maya Long Count Calendar included the end of the world, a new age of consciousness, a reversal of the Earths magnetic poles, the arrival of the Messiah, etc. Needless to say, none of those things happened. In any event, historical Maya records do not indicate that they gave much thought to what would happen at the end of the calendar. Sources: Burland, Cottie with Irene Nicholson and Harold Osborne.

How to Self-Educate with Reading the Right Books

How to Self-Educate with Reading the Right Books How to Read Useful Books that Don't Interest You Mark Zuckerberg, Bill Gates, and Warren Buffet read nearly 50 books a year. Impressed? These people have achieved colossal success and became famous throughout the world. Are they the richest, the most successful, or the most intelligent ones? This can be learned from the things they like to read and what motivates them in their lives. Well, you must agree that Bill Gates would not find novels exciting in his everyday life but would prefer books that develop and teach interesting things. The crucial point is that when choosing non-fiction books, you have to succeed with the content and find only high-quality information so as not to waste your time. But often it happens that people remain unhappy with their choice – usually, non-fiction books are not quite readable and are poorly perceived by the reader. They don’t pay attention to anything and, as a result, lose interest in self-development. The question is: â€Å"How to choose the right books and how to read them effectively and wisely?† What’s Wrong with Non-Fiction Books? If you come to any bookstore in your city, you will probably come across a ton of fiction books. Fiction books are specially designed and written to grab the attention of the buyer and make him purchase a book. If you do not pay attention to the cover then after looking inside and scanning a few pages, you still want to buy it. What is the reason? Fiction books are written in such a cunning way to always excite the reader and make him read every word attentively not to miss a single detail and read ‘till the very end. The focus is on the story: if the book has an interesting plot, since humans are curious, we are likely to read the whole written piece. Has it ever occurred to you that you found a non-fiction book as much exciting as a novel? Then you are just lucky and hit the right content. Unscientific books always cause more interest than scientific ones, although there is less meaning in them. In scientific books, in most cases, there is no plot, but they are made to answer an important question, teach some things, describe certain processes and so on. Of course, fiction books can also be useful, they increase vocabulary, contribute to the development of creativity and abstract thinking and also help find a common interest with people in some way. But, if you have a goal of self-educating and improving potential skills, you should give preference to self-improvement books. How to Choose the Right Self-Improvement Book? Quite often we hear such a statement "useful books are not always interesting, is it worth reading them?". The answer is simple: of course, they worth it. But you need to do this carefully, by following certain rules that help you maintain interest in reading useful books. First, you need to understand why you need a certain self-improvement book. Choose the study area or branch of knowledge and get the right context. Secondly, analyze your current life situation and think thoroughly about what you need. If you are looking for ways to make money, then read books about business marketing. If you want to get rid of any restrictions in your life and find peace - find a book about psychology. It is important here to clearly understand what you want, then you will always have the interest to read and also your current needs will get satisfied. A few small but useful tips for those who want to start reading self-improvement books: 1. Analyze yourself and your current life situation. As mentioned earlier, you should have a clear understanding of what is happening in your life at the moment. By analyzing yourself and your life situation, you will be able to realize your main problems and choose the most interesting and important questions for you. 2. Come up with the approximate answer. After introspection and identification of the main problem, visualize the solution to this problem or find an approximate answer to the question you need. After that, drive in the search for the name of your main problem and look for the desired option. 3. Evaluate a book before buying it. And the last advice for today - when seeking a book you need for self-development, be vigilant and carefully inspect the book. If you are searching online, read the positive and negative feedback from people, and also download the introductory part of the book. If you decide to buy a book in a regular store, look at its cover, read about the author, and think whether this book can help you.

Mandarin Vocabulary - Answering Questions

Mandarin Vocabulary - Answering Questions Mandarin does not have specific words for saying â€Å"yes† and â€Å"no.† Instead, the verb which is used in the Mandarin question is used to make a positive or negative reply. For example, if the question was: Do you like rice? The answer could be: I like.orI don’t like. Answering Mandarin Questions Mandarin questions can be answered with the question verb. This verb can be either positive (to answer â€Å"yes†) or negative (to answer â€Å"no†). The positive form of the verb is simply the verb repeated: Q: NÇ  xÇ huan fn ma?Do you like rice?ä ½  Ã¥â€"Å"æ ­ ¡Ã© £ ¯Ã¥â€"Ž?A: XÇ huan.(I) like.Ã¥â€"Å"æ ­ ¡ If you want to say you don’t like rice, you would say bà ¹ xÇ huan. The Mandarin No To answer â€Å"no† to a question, the negative form of the question verb is formed using the particle ä ¸  (bà ¹). The only â€Å"irregular† verb is æÅ"‰ (yÇ’u - to have), which uses æ ²â€™ (mà ©i) for its negative form. Mà ©i is also used for negating Functive Verbs (action verbs) when talking about past actions. In this situation, mà ©i is a short form for mà ©i yÇ’u and either form can be used. Mandarin Questions and Answers Q: NÇ  yÇ’u bÇ  ma?Do you have a pen?ä ½  Ã¦Å"‰ç ­â€ Ã¥â€"Ž?A: Mà ©i yÇ’u.No (don’t have).æ ²â€™Ã¦Å"‰Q: NÇ  yo bà º yo mÇŽi?Do you want to buy (it)?ä ½  Ã¨ ¦ Ã¤ ¸ Ã¨ ¦ Ã¨ ² ·?A: Yo.Yes (want).è ¦ Q: JÄ «ntiÄ n shà ¬ xÄ «ng qÄ « yÄ « ma?Is today Monday?ä »Å Ã¥ ¤ ©Ã¦Ëœ ¯Ã¦ËœÅ¸Ã¦Å"Ÿä ¸â‚¬Ã¥â€"Ž?A: Shà ¬.Yes (is).æ˜ ¯

Concept Paper based on Criminal Justice-related research topic that Essay

Concept Paper based on Criminal Justice-related research topic that you choose - Essay Example This is based on the fact that age differs from state to state. In most states, the lawful age of sexual consent is between the ages of 15- 18 years. In statutory rape, force and consent are not necessary for conviction. The defining factor in statutory rape is the age of the victim. Statutory rape is a crime, and the perpetrators have to go through the legal system of justice. Minors lack the capacity to provide meaningful consent to sex and should be protected against sexual exploitive behaviours by adults (Brody & Acker, 2011). During a criminal trial, a defendant may argue that he was unaware or mistaken about the age of the victim and is not guilty of rape. Most states however view statutory rape as a strict liability offense and have declined to allow defendants to raise the mistake of age defence at trial. Defendants are prosecuted regardless of their mistaken belief about the age of the victim (Carlan, Nored & Downey, 2011). Statistics shows that the majority of fathers of children born to teenage girls were adults; the United States Congress participated in the 1996 Federal Welfare reform law that urged states to enforce the law to reduce teenage pregnancies. More recent studies however show that majority of sexual offenders to teenage girls are teenage boys or males who are about the same age as the girls with whom they are having sex (Leitenberg & Saltzman, 2000). A study in 1995 revealed that 50% of teenagers in the U.S have had sex by the age of sixteen years which is a serious issue for criminal justice because the age of consent is 16 years. This according to the law is statutory rape despite the numbers of such cases rising in an alarming rate (Oberman, 2000). Leitenberg & Saltzman (2000) in their articles used a survey of a representative sample of participating adolescent girls between the ages of 13-15 years and between 8th- 12th grades. Cocca (2002) used case studies on her research. The concepts used in

DISCOVER can be used in conjunction with the SII to find more information on the careers from that assessment. One of the strengths of the SII is that it provides a lot of information that the student can take for further research. Also, it is completed easily, and it is based on the Holland codes which allows the individual to access other assessments that also use the codes. The strengths of the DISCOVER program are that it is computer based, interactive and engaging for the student. The reason it is important to be aware of the issues involved with assessments in special populations is because we cannot make generalizations that match everyone. This is why it is important to know how the tests were normed and the clients demographic profile. Starkey, D.S., and Rasmus, S.C. (2006). Individual and group assessment and appraisal in Capuzzi, D., and Stauffer, M.D. (2006) Career counseling: Foundations, perspectives and applications. Pp. 113-151. At 17 years old, John will have more time to choose a career, but it is a good time for him to explore careers. Although he worries about this now, I would also explain to him that he does not have to choose a solid career at this point because he has his whole life ahead of him. The two ethical considerations that Mrs. Catwick would have to take into consideration would first be to make sure that the test was appropriate for Johns age group. She is giving form R, which she hopefully reviewed or read the booklet to see whether this was appropriate for high school students. Another consideration, according to Engels and Harris (2006) is to make sure to inform John that the SDS is not a test in the way that he is used to taking. The reason for pointing this out is because there is "the high likelihood that clients

Justice System in the UAE - Research Paper Example † (Judicial System in Abu Dhabi par 13) on the other hand, Ras Al Khaimah does not have a Court of Cassation. The major source of law is legislation. The UAE mainly follows the system of civil law, inspired by the French and Roman legal systems as well as the Egyptian law of civil codes. The court system is generally inquisitorial, unbound by precedent and comprised of specifically skilled judicial officers. Despite being a federation of United Emirates, the judicial scheme is not all-inclusive or wide ranging, as some of the emirates have their own self-governing judicial systems. In spite of being an Islamic nation, the application of Shari’ah law is controlled and contractual as well as commercial transactions are controlled by written commercial laws and codes that can be relied upon by the needs of western businesses. The Justice system: The Justice system in the UAE is mainly based on the Constitution of the UAE? 1971 (Constitution). The federation has control over all affairs assigned to it in the Constitution. Each individual member of United Emirates has power over their own territories in all matters? rather than just the exclusive authority of the federation, as set out in the UAE Constitution. Additionally, every Emirate has a hereditary sovereign who exercises substantial control over his own Emirate. The 7 rulers, as members or associates of the Supreme Council, jointly exercise control over the UAE. The Sharia civil law systems are the chief sources of legislation (Constitution). Civil law system: The UAE functions in civil law statutes and such systems are the primary source of law. Decisions of the high courts in the UAE are not based on any decisions made by low courts. â€Å"In litigation matters, the pleadings submitted by the parties - plaints or written statements - play a determining role as the courts generally decide cases based upon them† (Latheef par 4). Every case is discussed and a decision is reached based on it s own facts and merits. Every proceeding in the court is in Arabic. All Non-Arabic documents filed in the court by appellants are to be converted into Arabic by a translator licensed by the Ministry of Justice. The Sharia: Generally, the Sharia is a body of ethical, religious and legal rules. The fundamental and basic roots of Islamic Sharia are: The Koran? which is a compilation of divinely ordained policies. The Sunna that includes the teachings of Prophet (Hadith), as well as an account of his proceeding and actions. Sharia is established on well-known concepts of equity and justice, and its practical effect in commercial matters is frequently the same as would be attained in Western law. â€Å"To say that the Shari’a should govern judicial decisions is to refer to a process rather than to specify a result. Shari’a itself includes different schools of thought on a number of legal issues. However, it is founded on familiar concepts of justice and equity, and the pra ctical result in commercial matters is often, though not always, the same as would be reached under Western jurisprudence† (United Arab Emirates par 257). For example, Sharia strives to provide effect to the party’s intention in matters of contract. On the other hand, the intention of the party may be in a different way construed by jurists in the two systems. For instance, one researcher has argued convincingly that in many cases? traditional Sharia would let go the parties

Qualitative Research Paper B - Essay Example We are surrounded by data everywhere. Our lives are influenced by data pertaining to the things we feel and see, the things we eat, the different things that we think about as also the constitution of our surroundings. Apart from this data that seems to engulf our lives, there is a separate class of data that one obtains as part of the quest to find answers to a specific question. In doing so, the efforts is often left with so much data that it is sometimes hard to ultimately determine the purpose for which the data has been collected let alone think of ways to analyze the collected data. What separates the data from information is the usefulness of the former, where analysis of data helps turn it or its subsequent outcomes into information. It is this information that helps one determine answers to questions and phenomenon that demands a structured effort. A question and its associated material that is being analyzed can be looked at from several perspectives. General forms of data and research analysis have always looked at answering the what, whom and where dimensions of the question and such an approach is hence known as quantitative approach as it tries to analyze quantifiable and measurable parameters. Nevertheless, many questions also arise with respect to why and how things occur. Answering questions determining the ‘why’ and ‘how’ of a phenomenon requires the analysis to take an approach that analyzes the answers across several subjects and disciplines and helps arrive at a thorough understanding. This form of research is trying to ascertain the quality associated with a phenomenon and is hence known as qualitative analysis. Qualitative analysis is a very simple technique at undertaking research and consists of three essential parts.

Reflective Report - Essay Example More importantly, the course has provided me with tools for creativity and for solving problems within the business environment through the successful application of these tools and ideas. The practical application of the creativity and innovation tools has enabled me to have a wider knowledge on how to approach problems in my career and in business and come up with solutions to solve the problems. Through the module, I was able to learn the importance of creativity and how it affects performance and failures in contemporary business practice as well as how to manage them. For instance from the theory of Zeger Degraeve I have learnt on how to create an organizational culture that fosters the business belief of taking risks, experimentation and innovation and he need to focus on the qualities of decision making rather than the outcomes alone. Through the theory of Zeger, I have learnt that the results of decisions is irrelevant as a measure of decision quality as the difference between the time lapse of the decision itself and the realization of the results. In the course of the module and on the basis of Zeger’s theories, I have learnt that the quality of decision is measured at the moment the decision is made as decision-making is always a process is based on valuing the alternatives at the moment they are available and the present information. I have also learnt that the process of making decisions is a reflective and analytical and must embrace the tenets of effective communication. In any business, my personal lessons from this theory is that one should be judged by the quality of their performance and that progress in the career should reflect our intrinsic quality of our contribution to the business in terms of decisions. I have also managed to grasp ideas on the stages of team development from the five-step analysis given by Tuckman as these are necessary for the team in handling the

Cultural Diversity in the U.S - Assignment Example The United States experiences racial conflicts, which have given birth to riots, clashes and discriminative attitude and behavior. Human rights activists always persuade to the government as well as law enforcing agencies for treating all individuals on equal foundations by offering them equal education, health, business, recreational, sports and job opportunities, so that future generations could be protected from the bloody clashes because of the unequal distribution of wealth, resources and opportunities imposed and inflicted upon the minority groups by the political, social, educational and economic institutions. Affirmative action has been in vogue in almost all states, cities and institutions of the USA particularly for the last four decades, and laws strictly condemns application of any discrimination on the individuals. â€Å"There are thousands of examples of situations where people of color, white women, and working class women and men of all races who were previously excl uded from jobs or educational opportunities, or were denied opportunities once admitted, have gained access through affirmative action.† (Kivel, 1997: 3) Now, no public or private reject to recruit the black, female or gay candidates to obtain employment because of their complexion, gender or sexual orientation etc. Race-sensitive admissions policies have also been adopted at schools, colleges and other educational institutions. Actually, social discrimination is not confined to employment and job only in the USA. Rather, the same prejudiced behavior could be observed in healthcare services and various educational institutions too. It was particularly the case in past when an overwhelming majority of teachers, staff members and students, belonging to white Anglo Saxon population (WASP) displayed their hatred by teasing the Black students through different ways; even separate water coolers and washrooms

Basics Of Embedded Systems

Basics Of Embedded Systems The term embedded systems is quite a complex one. Simply put, it is a combination of hardware and software that performs the component of a larger system. A few years ago embedded technology existed in stand alone devices such as vending machines and copiers that did their jobs with little regards for what went on around them. But as technology advance to connect devices to the internet and to each other, the potential of embedded technology has increased. Home appliances, mobile phones, cars, tiny micro chips, avionics etc.., are all using embedded technology. High-profile embedded chips are scaleable, generate small amounts of heat, and consume less power. These are generally preferred for their speed, accuracy and reliability. As they are compact in size and ability to perform time-critical and task specific operators, embedded devices find application in all segments of industrial and commercial market places and home appliances. In recent years,it became apparent that control systems as integral components of larger systems, should be developed and designed concurrently with mechanics, hydraulics, and electronics. It is important that engineers have a good understanding of the implications of software technology embedded into traditional engineering systems. Current machines consist of physical components providing the means and a control system employing those means to fulfill the machines function. Together, they build up the controlled machine, which can also be called an embedded system. . New innovative applications in different areas will make embedded systems as one of the fastest developing technology of the near future. This paper deals with concepts and developments of embedded systems in control of machines and gives a general overview of the basic components of control systems, ranging from sensors to actuators. Embedded Systems An embedded system employs a combination of hardware software (a computational engine) to perform a specific function; is part of a larger system that may not be a computer; works in a reactive and time-constrained environment. Software is used for providing features and flexibility Hardware = {Processors, ASICs, Memory} is used for performance ( sometimes security) The term embedded system can be used for a wide range of applications and devices. A useful definition is not easy to formulate. Boasson mentioned one characteristic that applies to all embedded systems: Neither the computer system without the special environment in which it is embedded, nor the environment without the computer system has any significance in itself. An embedded system employs a combination of hardware software (a computational engine) to perform a specific function; is part of a larger system that may not be a computer; works in a reactive and time-constrained environment. Basics of Embedded systems An embedded systems typically comprises the hardware, embedded RTOS, device drivers, communication stacks and embedded application software. Embedded hardware: The embedded hardware mainly consists of a microcontroller with various peripheral ICs. A fixed size volatile memory such as DRAM or SRAM and non volatile memory such as Flash or EPROM, connected to the microcontroller, are an integral part of the device. Depending on the targeted application of the device, the peripheral can include communication device such as serial controller, Ethernet controller, or a wireless communication controller and other application-specific ICs (ASICs). Many handheld devices these days also have sensors, actuators, keypads and graphical LCD screens as user interfaces. The only way a embedded machine control system can get information about its surroundings, is through the use of sensors and/or sensor systems. Control signals from the embedded control are converted into power and/or movement through Actuators. Sensors: During the past years a shift has taken place from mechanization towards automation. This implies the extensive use of sensors (and actuators) in order to be able to actually control (and influence) the actions that are performed by the controlled system.In principle the task of a sensor is fairly simple. It transforms an input signal that usually is difficult to handle in its original form to a more manageable form. Between input and output of the sensor a number of processes take place to obtain the desired result, as schematically shown in Figure. Actuators: Actuators come in many forms and shapes. They act as the arms and legs of the machine. Actuators convert control signals into power and/or movement,as schematically shown in Figure below. Control signals do not have to be of electrical nature, also other kinds are possible. The power conversion can be done in a number of ways. The most common energy sources for actuators are: à ¢Ã¢â€š ¬Ã‚ ¢ Compressed air, pneumatics à ¢Ã¢â€š ¬Ã‚ ¢ Pressured oil, hydraulics à ¢Ã¢â€š ¬Ã‚ ¢ Electricity, electro mechanics Embedded RTOS: The concept of real-time operating system (RTOS) is inseparable when we talk about embedded systems. All intelligent devices that perform complex functions have an embedded operating system inside. A real-time operating system (RTOS) is built for specific applications and guarantees response to an external event with in a specified time constraint. This operating system is typically real time in nature, i.e. it is capable of responding deterministically to time-critical external events. For example, when you suddenly apply brakes for your car to avoid an accident, the intelligent gad-get responds immediately. Imagine the plight of a driver if there is no responseà ¢Ã¢â€š ¬Ã‚ ¦ the result is obvious. Device drivers: The lowest-level software that acts as glue between the operating system and the peripheral devices is called the device driver. The device driver software controls every peripheral device that is connected to the micro controller. Communication stacks: If the embedded device is capable of communicating to the external world, it has a communication software stack running on the top of the operating system. In order to connect to the Internet, the embedded device needs a TCP/IP stack. Characteristics of Embedded systems are: Small, low power, high performance Compact efficient use of PCB / IC real-estate Maximum output for minimum size High MIPS to power ratio High bus bandwidth Low interface bottlenecks Advantages: Customization yields lower area, power, cost Disadvantages: Higher HW/software development overhead. Design, compilers, debuggers May result in delayed time to market! Control Systems Control system is the section where the system senses the input by sensors and compares with the internal reference of the system and gives the output obtained through the actuators as shown in figure below. Control systems implementations: Looking at the history of controllers, we can distinguish six types of control systems: à ¢Ã¢â€š ¬Ã‚ ¢ Black box or embedded control à ¢Ã¢â€š ¬Ã‚ ¢ Relay-based logic control à ¢Ã¢â€š ¬Ã‚ ¢ Single-board control (SBC) à ¢Ã¢â€š ¬Ã‚ ¢ Programmable control (PLC) à ¢Ã¢â€š ¬Ã‚ ¢ Computer numerical control (CNC) à ¢Ã¢â€š ¬Ã‚ ¢ Distributed control systems (DCS) Black box or embedded control: Embedded control is all around us. More and more household appliances are being designed with some form of embedded control in it. Washing machines, microwave ovens, car radios, cellular phones, VCRs, and digital photo cameras are just a few examples of ordinary devices with embedded control in it. Embedded control is used in product itself, not in the production system with which the products are manufactured. The use of embedded control software enables product designers to design smarter products with a large portion of its functionality embedded in the software of the product. This results in increased product flexibility and the possibility to change or add new functionality without having to redesign the physical product. So, in a way the software has become the product. Relay-based logic control: Before electronic control was developed, relays (as well as pneumatic and hydraulic components) were widely used as control elements. They serve as switching, timing and multiplying mechanisms for input devices such as switches, push buttons, photo-electric sensors, etc. Since the control is hard-wired, flexibility is low and troubleshooting difficult. Today, they are less used in the actual control functions but many control applications use relays in conjunction with the more sophisticated forms of control for isolation and other specialized electromechanical functions. Single-board Control (SBC): Electronic controllers on circuit boards first appeared in the 1960s. The early ones consisted of logic modules with lots of discrete components like transistors, capacitors, resistors, etc. on them with which the desired control functions were implemented. Later on, integrated circuits (LSI, VLSI) are applied. Since no moving parts are used they are inherently more reliable than relay-based control systems. Because they are custom-made, maintenance and repair can be a problem. Many original equipment manufacturers still choose to design their own single-board controllers for their own unique machine applications. Programmable logic controller (PLC): The need for more flexibility in control systems has led to the development of the programmable logic controller, the PLC. In the early seventies, the automotive industry was growing rapidly. In order to be able to react more quickly to a changing demand in the marketplace, one had to have a more flexible, easily adaptable and expandable control system; therefore it had to be a programmable control system. The early PLCs were programmed in so-called relay ladder. Today, high level programming languages like Pascal, C/C++ and even Java are being used to program PLC(-like) systems. Computer Numerical Control (CNC): Essentially, numerical control is nothing more than sending a sequence of commands to a machine, that in turn interprets them and performs the desired movement and machining actions. Before the introduction of NC these commands were issued manually by pressing buttons and switches, turning handwheels, etc. The path information is presented in numeric coordinate values (X, Y, Z), hence the name numerical control. Distributed Control System (DCS): Relay-based control, SBC and PLC are widely used in the discrete production area. The process industry is the domain of distributed control systems, where the number of analog I/O points exceeds the number of discrete I/O points. DCSs are used where the controlled process is continuous, has a high analog content and throughput, is distributed across a large geographical area and where down time is very expensive. Embedded Systems in Control of Machines In early days, the major part of the control was built into the physical machine, using mechanical parts. Although hardware-based control is still widely applied, major developments take place in the field of software-based control. An increasing part of the design process deals with the software of the control system. The development of the microprocessor and subsequent gain in flexibility has contributed a great deal to this Controlled machine Current machines consist of a physical machine providing the means, and a machine control system employing those means to fulfill the machines function. Together, they build up the controlled machine, also called an embedded system. The term embedded system is used for a wide range of applications or devices. The physical machine can be considered to consist of three subsystems: the main structure, actuators and sensors. The main structure physically connects the parts of the two remaining sub systems. The machine control system sends information to the actuators and receives information from the sensors via the I/O-interface. The machine control system can be divided into five functional subsystems: à ¢Ã¢â€š ¬Ã‚ ¢ Regulative control, also referred to as direct control or feedback à ¢Ã¢â€š ¬Ã‚ ¢ Error-handling control, also referred to as fault detection and isolation (FDI) or exception à ¢Ã¢â€š ¬Ã‚ ¢ Supervisory control also referred to as logic control. à ¢Ã¢â€š ¬Ã‚ ¢ The data processing subsystem stores and manipulates gathered data. à ¢Ã¢â€š ¬Ã‚ ¢ The user interface subsystem allows the user to interact with the machine-control system. The machine control system can also be regarded as a layered control system, as shown in Figure. The bottom layer interacts directly with the actuators and sensors, that is, the physical machine. Some components are controlled directly (for instance, pneumatic components).Some components are controlled by regulative control (for instance, motorized manipulators) or by both regulative and error-handling control subsystem (for instance, robot arms). Some components are controlled by an error-handling subsystem only (for instance, warning lamps or safety locks). The intermediate layer is involved in scheduling, coordinating control of individual machine components, gathering and processing data, monitoring and compensating possible machine failures, and providing the top layer with the required information on the machine status. The top layer allows the user to interact with and to monitor the machine. Machine control is closely related to manufacturing control. The goal of machine control is to perform certain manufacturing functions in a controlled manner. Machine control enables us to influence production means in such a way that the manufacturing process produces the desired products of the correct quality at the planned time in the required quantity. Over the years, a lot of developments have taken place in production methods, machine design and machine control design. Not surprisingly, they all influence each other. In the route from manual work to automation we can distinguish five phases of mechanization or automation. The meaning of the term phase of mechanization is the extent to which a machine or production system can function independently, without human intervention. Manual labour with tools Specific machines Universal machines Multiple link specific machines Multiple specific Intelligent control In universal machines, control is embedded in the machine itself, through the use of mechanical parts like eccentrics, cams, camshafts, springs, gearboxes, drive axis, etc. The result depends less on the quality of the worker and more on the quality of the machine. To avoid unnecessary delays, attention has to be paid to operating procedures, work preparation, material handling and tool preparation. An example of an embedded control system: Dryer Different sub systems in the dryer are Main structure: The motor Sensors : Temperature sensor, humidity sensor Actuators : Motor driver control, fan control Machine control system : SAB-C504 Examples: Consumer electronics: e.g., cameras, camcorders . Consumer products: e.g., washers, microwave ovens Automobiles (anti-lock braking, engine control ) Industrial process controllers avionics/defense applications Computer/Communication products: e.g., printers, FAX machines Emerging multimedia applications consumer electronics: e.g., cellular phones, personal digital assistants, videoconferencing servers, interactive game boxes, TV set-top boxes Multimedia: Increasing computational demands, and increased reliance on VLSI, HW/SW integration. Embedded software can support such applications as the Internet, e-mail and MP3 decoders etc. They also support sophisticated graphical user interface screens. The automatic DAM DOOR opening systems is a system where the DAM DOORS is controlled on the speed of the raising water. A situation araises where the raising water in the river may be very fast as the rainfall increases. If the river is blocked by a DAM then the speed of the raising water will obviously rise very soon. To prevent this raising and to prevent flooding of the river bank the DAM DOORS has to be opened but with a controlled speed because there is no point on opening the DOOR slowly if the water is raising at a quicker pace. It is a circuit to measure the flow rate of water .Using this device one can determine the total volume of water raised in the river. The instrument is a microcontroller based system. It can have a optional of manual operation. In manual method of measuring the flow rate of water, we need to observe the rise of water in river .As soon as water reaches a fixed point in the river , we press start button on the stopwatch .After the water reaches another fixed point, we need to press stop button on the stopwatch. The observed time and level are used to calculate the flow rate of the water. Flow rate = volume/time But in this procedure there are chances of errors . The device eliminates the errors and has the following features. Automatically senses the level and generates triggering pulses for counting of the elapsed time there by providing basis for calculation of the flow rate of waters. Includes the circuit for digital display of the elapsed time using MICROCONTROLLER as well as a 7-segment display. DESCRIPTION : The circuit can be divided into four blocks ,namely ,sensor ,logic controller ,pulse generator ,switching module. The sensor section for conducting waters: Sensor 1 is permanently connected to circuit ground, while sensors 2 and 3 should/might be connected to positive supply via some pull up resistors. When the water level touches sensor 2 and/or sensor 3, 2 and/or 3 are pulled low towards ground potential. As a MODEL PROJECT we can use small spherical stainless steel probes as sensors and screw the wires coming from the circuit to them . To avoid oxidation and sulphation of the naked portion, we can cover the joints using araldite or any other suitable epoxy compound .For longlife and protection against weather, we can use Teflon-insulated multistrand wires . For proper support wires along with the probes , a PVC support rod may be used for tying the wires to PVC rod to keep them in their proper position. The logical control section: This section might comprises a quad two-input NOR gates. When the water level is so slow that both sensors 2 and 3 are out of the water , the voltage at input of NOR gates may become logic 1 ,while their other input terminals may be logic 0. So the output pins of NOR gates are at logic 0. The output of those/that NOR gates connected to sensor 2 and 3 and the output of those/that NOR gates from sensor 1 are terminated at another NOR gate where in we get logic 0. The logic controling cuircuit is proposed to be designed to give an apropriate logical output acording to the the sensor inputs. The output This final output of the logic control unit is proposed to keep the pulse generator formed by timer IC. It is decided that the timer IC will be 555. When the water level rises to touch sensor 2 the output of the NOR gates combination should be logic 1,which initiates the operation of the pulse generator. When the water level further rises to touch sensor 3, the output of NOR gate will be logic 0, which should be in a position to terminate the operation of the pulse generator. In this way, the pulse generator can be automatically controlled as per other requirement. Pulse generator: Timer IC 555 will be used in out project to generate pulses with pulse recurrence frequency of 1 Hz. The frequency /period of the astable should depend on combination of resistences , capasitences and variable resistences also. The switching section: The switching module is used to make and break switch contacts at 1 Hz rate, using the output of the timer IC555 . This function analogous to pressing/releasing of a push-to -on switch once a second . An optocoupler is proposed to be used for making/breaking contact between to points. Whenever the output of timer IC555 goes high, the optocoupler conducts . this optocoupler is connected to the microcontroller KIT. The road ahead Telematics: The impact of telematics would be really innovative. With access to e-mail the internet, and telephone services, car occupants could shop and bank online, receive traffic and navigation information, and avail of remote diagnostics facilities Automotive electronics: Remember the talking car in the serial knight rider, a fully computerized car capable of doing almost everything a car lover would want to. Seems like a fantasy but the day is not far when almost all automobiles would interact with computers on dash- boards. From ordering a pizza to booking tickets at the nearest theaters, things would be as easy as giving orders to your servant. Whole of which would be possible with embedded systems. Mistral software is in the process of developing text to speech and speech reorganization technologies to give the car occupants the ultimate comfort. Whenever theres a call on your mobile, you need not get jumpy at the very onset of the call. The computer in the cars dashboard would do the job for you. GPS navigation guides you safely through the traffic. The GPS interface in the car pinpoints your exact location on a map. In case GPS signal cant be received due to high density of tall buildings or other magnetic interface, the dead reckoning technique, which works for short durations, guides you effectively. The system is also loaded with GSM/CDMA protocol standards. Biomedical solutions: The biomedical chord developed by mistral is a centrelised patient monitering system that allows remote monitering of up to 32 patients at a given time through a central computer. It can process of maximum of 32 channels usin the state-of-the-art DSP in a PC environment. Economy: The world of embedded systems is a dreamers paradise with unlimited possibilities. According to the global market size for embedded software development alone was $7 billion in 2001, which is expected to reach $20 billion in 2003 and $31 billion by 2005.For India are $400 million. $750 million and $1.1 billion respectively. In India RD in embedded system was worth $1.1 billion in 2001, which would grow to $8 billion by 2008. CONCLUSION: Further more, embedded systems are rapidly becoming a catalyst for change in the computing, data communications, telecommunications, industrial control and entertainment sectors. Automatic systems in any field will be useful and will save the people and organizations. New innovative applications in these as well as other areas will make embedded systems as one of the fastest developing technology of the near future.Thus the embedded system plays an important role in our day today life.

Morrisons Beloved: A Review :: essays research papers

Morrison's Beloved: A Review Everything in a novel is there only because the author chooses it to be there: characters, plot devices, structure and pacing, tone, etc. all are ways in which the author says what he/she has to say. Morrison implements different characters and ideas to enhance the slavery of the time and its lasting affects. While the story is of heartbreak there are various representations of concepts. Which can be seen through realism and the characters of Mr. Bodwin and Baby Suggs. Mr. Bodwin is a white abolitionist and has high hopes for blacks in the future. He spends the happiest years of his life struggling for emancipation of blacks. Mr. Bodwin represents a time in history where slavery starts to come into question. People (white) started to realize this travesty and begin to speak up and act towards the abolition of slavery. The abolitionists begin a process which will eventually end in the 60's where blacks will attain complete freedom. They begin a legacy of freedom fighters that will not stop till blacks receive the right they so deserved. Future leaders of known fame will be Malcolm X and Martin Luther King which will carry on this battle begun by the abolitionists. Baby Suggs, is Halle's mother and Sethe's mother - in - law, and is an important character in the story in that she brings about many aspects of self- pride and versatility. Suggs lived through the "slavery" and came out of the ordeal with strength of her character alone. Slavery at the time broke down the slaves making them have low self- esteem and low worth. But Suggs brings about the part of resiliency that was needed to beat the "system." Her faith in God and self makes her the prominent legacy. As she rose above slavery so have other individual rose above persecution and hardship across the years. For instance, World Wars, Holocaust, and the depression to name a few. Morrison throughout Beloved offers realism of the times and consequences that occurred with the slaves. Morrison paints a picture post -Civil War life that leaves many black people lost in America. Blacks after the civil War emerged all across the South with no place to go. The South was in ruins in every sense and the Black freed slaves were confused. They had been separated from their families, lost any property they may have had, they wandered in search of a better life. Just because Slavery was abolished didn't mean all was

Example Research: Critical Discourse Analysis

18 Critical Discourse Analysis TEUN A. VAN DIJK 0 Introduction: What Is Critical Discourse Analysis? Critical discourse analysis (CDA) is a type of discourse analytical research that primarily studies the way social power abuse, dominance, and inequality are enacted, reproduced, and resisted by text and talk in the social and political context. With such dissident research, critical discourse analysts take explicit position, and thus want to understand, expose, and ultimately resist social inequality.Some of the tenets of CDA can already be found in the critical theory of the Frankfurt School before the Second World War (Agger 1992b; Rasmussen 1996). Its current focus on language and discourse was initiated with the â€Å"critical linguistics† that emerged (mostly in the UK and Australia) at the end of the 1970s (Fowler et al. 1979; see also Mey 1985).CDA has also counterparts in â€Å"critical† developments in sociolinguistics, psychology, and the social sciences, some already dating back to the early 1970s (Birnbaum 1971; Calhoun 1995; Fay 1987; Fox and Prilleltensky 1997; Hymes 1972; Ibanez and Iniguez 1997; Singh 1996; Thomas 1993; Turkel 1996; Wodak 1996). As is the case in these neighboring disciplines, CDA may be seen as a reaction against the dominant formal (often â€Å"asocial† or â€Å"uncritical†) paradigms of the 1960s and 1970s.CDA is not so much a direction, school, or specialization next to the many other â€Å"approaches† in discourse studies. Rather, it aims to offer a different â€Å"mode† or â€Å"perspective† of theorizing, analysis, and application throughout the whole field. We may find a more or less critical perspective in such diverse areas as pragmatics, conversation analysis, narrative analysis, rhetoric, stylistics, sociolinguistics, ethnography, or media analysis, among others. Crucial for critical discourse analysts is the explicit awareness of their role in society.Continuing a tra dition that rejects the possibility of a â€Å"value-free† science, they argue that science, and especially scholarly discourse, are inherently part of and influenced by social structure, and produced in social interaction. Instead of denying or ignoring such a relation between scholarship and society, they plead that such relations be studied and accounted for in their own right, and that scholarly practices Critical Discourse Analysis 353 be based on such insights. Theory formation, description, and explanation, also in discourse analysis, are sociopolitically â€Å"situated,† whether we like it or not.Reflection on the role of scholars in society and the polity thus becomes an inherent part of the discourse analytical enterprise. This may mean, among other things, that discourse analysts conduct research in solidarity and cooperation with dominated groups. Critical research on discourse needs to satisfy a number of requirements in order to effectively realize its ai ms: †¢ †¢ †¢ †¢ †¢ As is often the case for more marginal research traditions, CDA research has to be â€Å"better† than other research in order to be accepted.It focuses primarily on , social problems and political issues, rather than on current paradigms and fashions. Empirically adequate critical analysis of social problems is usually multidisciplinary. Rather than merely describe discourse structures, it tries to explain them in terms of properties of social interaction and especially social structure. More specifically, CDA focuses on the ways discourse structures enact, confirm, legitimate, reproduce, or challenge relations of power and dominance in society. Fairclough and Wodak (1997: 271-80) summarize the main tenets of CDA as follows: 1. 2. 3. 4. 5. . 7. 8. CDA addresses social problems Power relations are discursive Discourse constitutes society and culture Discourse does ideological work Discourse is historical The link between text and soc iety is mediated Discourse analysis is interpretative and explanatory Discourse is a form of social action. Whereas some of these tenets have also been discussed above, others need a more systematic theoretical analysis, of which we shall present some fragments here as a more or less general basis for the main principles of CDA (for details about these aims of critical discourse and language studies, see, e. . , Caldas-Coulthard and Coulthard 1996; Fairclough 1992a, 1995a; Fairclough and Wodak 1997; Fowler et al. 1979; van Dijk 1993b). 1 Conceptual and Theoretical Frameworks Since CDA is not a specific direction of research, it does not have a unitary theoretical framework. Within the aims mentioned above, there are many types of CDA, and these may be theoretically and analytically quite diverse. Critical analysis of conversation is very different from an analysis of news reports in the press or of lessons and teaching at school.Yet, given the common perspective and the general aims of CDA, we may also find overall conceptual and theoretical frameworks that are closely related. As suggested, most kinds of CDA will ask questions about the way specific 354 Teun A. van Dijk discourse structures are deployed in the reproduction of social dominance, whether they are part of a conversation or a news report or other genres and contexts.Thus, the typical vocabulary of many scholars in CDA will feature such notions as â€Å"power,† â€Å"dominance,† â€Å"hegemony,† â€Å"ideology,† â€Å"class,† â€Å"gender,† â€Å"race,† â€Å"discrimination,† â€Å"interests,† â€Å"reproduction,† â€Å"institutions,† â€Å"social structure,† and â€Å"social order,† besides the more familiar discourse analytical notions. ‘ In this section, I focus on a number of basic concepts themselves, and thus devise a theoretical framework that critically relates discourse, cognition, and society. 1. 1 Macro vs. microLanguage use, discourse, verbal interaction, and communication belong to the microlevel of the social order. Power, dominance, and inequality between social groups are typically terms that belong to a macrolevel of analysis. This means that CDA has to theoretically bridge the well-known â€Å"gap† between micro and macro approaches, which is of course a distinction that is a sociological construct in its own right (Alexander et al. 1987; Knorr-Cetina and Cicourel 1981). In everyday interaction and experience the macro- and microlevel (and intermediary â€Å"mesolevels†) form one unified whole.For instance, a racist speech in parliament is a discourse at the microlevel of social interaction in the specific situation of a debate, but at the same time may enact or be a constituent part of legislation or the reproduction of racism at the macrolevel. There are several ways to analyze and bridge these levels, and thus to arrive at a unified critical anal ysis: Members–groups: Language users-engage in discourse as members of (several) social groups, organizations, or institutions; and conversely, groups thus may act â€Å"by† their members. Actions–process: Social acts of individual actors are thus constituent parts of group actions and social processes, such as legislation, newsmaking, or the reproduction of racism. 3 Context–social structure: Situations of discursive interaction are similarly part or constitutive of social structure; for example, a press conference may be a typical practice of organizations and media institutions. That is, â€Å"local† and more â€Å"global† contexts are closely related, and both exercise constraints on discourse. Personal and social cognition: Language users as social actors have both personal and social cognition: personal memories, knowledge and opinions, as well as those shared with members of the group or culture as a whole. Both types of cognition inf luence interaction and discourse of individual members, whereas shared â€Å"social representations† govern the collective actions of a group. 1 1. 2 Power as control A central notion in most critical work on discourse is that of power, and more specifically the social power of groups or institutions.Summarizing a complex philosophical and social analysis, we will define social power in terms of control. Thus, groups have Critical Discourse Analysis 355 (more or less) power if they are able to (more or less) control the acts and minds of (members of) other groups. This ability presupposes a power base of privileged access to scarce social resources, such as force, money, status, fame, knowledge, information, â€Å"culture,† or indeed various forms of public discourse and communication (of the vast literature on power, see, e. . , Lukes 1986; Wrong 1979). Different types of power may be distinguished according to the various resources employed to exercise such power: th e coercive power of the military and of violent men will rather be based on force, the rich will have power because of their money, whereas the more or less persuasive power of parents, professors, or journalists may be based on knowledge, information, or authority. Note also that power is seldom absolute.Groups may more or less control other groups, or only control them in specific situations or social domains. Moreover, dominated groups may more or less resist, accept, condone, comply with, or legitimate such power, and even find it â€Å"natural. † The power of dominant groups may be integrated in laws, rules, norms, habits, and even a quite general consensus, and thus take the form of what Gramsci called â€Å"hegemony† (Gramsci 1971). Class domination, sexism, and racism are characteristic examples of such hegemony.Note also that power is not always exercised in obviously abusive acts of dominant group members, but may be enacted in the myriad of taken-for-granted actions of everyday life, as is typically the case in the many forms of everyday sexism or racism (Essed 1991). Similarly, not all members of a powerful group are always more powerful than all members of dominated groups: power is only defined here for groups as a whole. For our analysis of the relations between discourse and power, thus, we first find that access to specific forms of discourse, e. . those of politics, the media, or science, is itself a power resource. Secondly, as suggested earlier, action is controlled by our minds. So, if we are able to influence people's minds, e. g. their knowledge or opinions, we indirectly may control (some of) their actions, as we know from persuasion and manipulation. Closing the discourse–power circle, finally, this means that those groups who control most influential discourse also have more chances to control the minds and actions of others.Simplifying these very intricate relationships even further for this chapter, we can split up the issue of discursive power into two basic questions for CDA research: 1 How do (more) powerful groups control public discourse? 2 How does such discourse control mind and action of (less) powerful groups, and what are the social consequences of such control, such as social inequality? I address each question below. ‘ 1. 2. 1 Control of public discourseWe have seen that among many other resources that define the power base of a group or institution, access to or control over public discourse and communication is an important â€Å"symbolic† resource, as is the case for knowledge and information (van Dijk 1996). Most people have active control only over everyday talk with family members, friends, or colleagues, and passive control over, e. g. media usage. In many 356 Teun A. van Dijk situations, ordinary people are more or less passive targets of text or talk, e. g. f their bosses or teachers, or of the authorities, such as police officers, judges, welfare bureaucr ats, or tax inspectors, who may simply tell them what (not) to believe or what to do. On the other hand, members of more powerful social groups and institutions, and especially their leaders (the elites), have more or less exclusive access to, and control over, one or more types of public discourse. Thus, professors control scholarly discourse, teachers educational discourse, journalists media discourse, lawyers legal discourse, and politicians policy and other public political discourse.Those who have more control over more — and more influential — discourse (and more discourse properties) are by that definition also more powerful. In other words, we here propose a discursive definition (as well as a practical diagnostic) of one of the crucial constituents of social power. These notions of discourse access and control are very general, and it is one of the tasks of CDA to spell out these forms of power. Thus, if discourse is defined in terms of complex communicative e vents, access and control may be defined both for the context and for the structures of text and talk themselves.Context is defined as the mentally represented structure of those properties of the social situation that are relevant for the production or comprehension of discourse (Duranti and Goodwin 1992; van Dijk 1998b). It consists of such categories as the overall definition of the situation, setting (time, place), ongoing actions (including discourses and discourse genres), participants in various communicative, social, or institutional roles, as well as their mental representations: goals, knowledge, opinions, attitudes, and ideologies. Controlling context involves control over one or more of these categories, e. . determining the definition of the communicative situation, deciding on time and place of the communicative event, or on which participants may or must be present, and in which roles, or what knowledge or opinions they should (not) have, and which social actions may or must be accomplished by discourse. Also crucial in the enactment or exercise of group power is control not only over content, but over the structures of text and talk. Relating text and context, thus, we already saw that (members of) powerful groups may decide on the (possible) discourse genre(s) or speech acts of an occasion.A teacher or judge may require a direct answer from a student or suspect, respectively, and not a personal story or an argument (Wodak 1984a, 1986). More critically, we may examine how powerful speakers may abuse their power in such situations, e. g. when police officers use force to get a confession from a suspect (Linell and Jonsson 1991), or when male editors exclude women from writing economic news (van Zoonen 1994). Similarly, genres typically have conventional schemas consisting of various categories. Access to some of these may be prohibited or obligatory, e. . some greetings in a conversation may only be used by speakers of a specific social group, r ank, age, or gender (Irvine 1974). Also vital for all discourse and communication is who controls the topics (semantic macrostructures) and topic change, as when editors decide what news topics will be covered (Gans 1979; van Dijk 1988a, 1988b), professors decide what topics will be dealt with in class, or men control topics and topic change in conversations with women (Palmer 1989; Fishman 1983; Leet-Pellegrini 1980; Lindegren-Lerman 1983).Critical Discourse Analysis 357 Although most discourse control is contextual or global, even local details of meaning, form, or style may be controlled, e. g. the details of an answer in class or court, or choice of lexical items or jargon in courtrooms, classrooms or newsrooms (Martin Rojo 1994). In many situations, volume may be controlled and speakers ordered to â€Å"keep their voice down† or to â€Å"keep quiet,† women may be â€Å"silenced† in many ways (Houston and Kramarae 1991), and in some cultures one needs to â⠂¬Å"mumble† as a form of respect (Albert 1972).The public use of specific words may be banned as subversive in a dictatorship, and discursive challenges to culturally dominant groups (e. g. white, western males) by their multicultural opponents may be ridiculed in the media as â€Å"politically correct† (Williams 1995). And finally, action and interaction dimensions of discourse may be controlled by prescribing or proscribing specific speech acts, and by selectively distributing or interrupting turns (see also Diamond 1996).In sum, virtually all levels and structures of context, text, and talk can in principle be more or less controlled by powerful speakers, and such power may be abused at the expense of other participants. It should, however, be stressed that talk and text do not always and directly enact or embody the overall power relations between groups: it is always the context that may interfere with, reinforce, or otherwise transform such relationships. 1. 2. 2 Mind control If controlling discourse is a first major form of power, controlling people's minds is the other fundamental way to reproduce dominance and hegemony. Within a CDA framework, â€Å"mind control† involves even more than just acquiring beliefs about the world through discourse and communication. Suggested below are ways that power and dominance are involved in mind control. First, recipients tend to accept beliefs, knowledge, and opinions (unless they are inconsistent with their personal beliefs and experiences) through discourse from what they see as authoritative, trustworthy, or credible sources, such as scholars, experts, professionals, or reliable media (Nesler et al. 1993). Second, in some situations participants are obliged to be recipients of discourse, e. . in education and in many job situations. Lessons, learning materials, job instructions, and other discourse types in such cases may need to be attended to, interpreted, and learned as intended by institu tional or organizational authors (Giroux 1981). Third, in many situations there are no pubic discourses or media that may provide information from which alternative beliefs may be derived (Downing 1984). Fourth, and closely related to the previous points, recipients may not have the knowledge and beliefs needed to challenge the discourses or information they are exposed to (Wodak 1987).Whereas these conditions of mind control are largely contextual (they say something about the participants of a communicative event), other conditions are discursive, that is, a function of the structures and strategies of text or talk itself. In other words, given a specific context, certain meanings and forms of discourse have more influence on people's minds than others, as the very notion of â€Å"persuasion† and a tradition of 2000 years of rhetoric may show. ‘ Once we have elementary insight into some of the structures of the mind, and what it means to control it, the crucial questi on is how discourse and its structures are able 58 Teun A. van Dijk to exercise such control. As suggested above, such discursive influence may be due to context as well as to the structures of text and talk themselves. Contextually based control derives from the fact that people understand and represent not only text and talk, but also the whole communicative situation. Thus, CDA typically studies how context features (such as the properties of language users of powerful groups) influence the ways members of dominated groups define the communicative situation in â€Å"preferred context models† (Martin Rojo and van Dijk 1997).CDA also focuses on how discourse structures influence mental representations. At the global level of discourse, topics may influence what people see as the most important information of text or talk, and thus correspond to the top levels of their mental models. For example, expressing such a topic in a headline in news may powerfully influence how an ev ent is defined in terms of a â€Å"preferred† mental model (e. g. when crime committed by minorities is typically topicalized and headlined in the press: Duin et al. 988; van Dijk 1991). Similarly, argumentation may be persuasive because of the social opinions that are â€Å"hidden† in its implicit premises and thus taken for granted by the recipients, e. g. immigration may thus be restricted if it is presupposed in a parliamentary debate that all refugees are â€Å"illegal† (see the contributions in Wodak and van Dijk 2000) Likewise, at the local level, in order to understand discourse meaning and coherence, people may need models featuring beliefs that remain implicit (presupposed) in discourse.Thus, a typical feature of manipulation is to communicate beliefs implicitly, that is, without actually asserting them, and with less chance that they will be challenged. These few examples show how various types of discourse structure may influence the formation and ch ange of mental models and social representations. If dominant groups, and especially their elites, largely control public discourse and its structures, they thus also have more control over the minds of the public at large. However, such control has its limits.The complexity of comprehension, and the formation and change of beliefs, are such that one cannot always predict which features of a specific text or talk will have which effects on the minds of specific recipients. These brief remarks have provided us with a very general picture of how discourse is involved in dominance (power abuse) and in the production and reproduction of social inequality. It is the aim of CDA to examine these relationships in more detail. In the next section, we review several areas of CDA research in which these relationships are investigated. ‘ 2 Research in Critical Discourse AnalysisAlthough most discourse studies dealing with any aspect of power, domination, and social inequality have not bee n explicitly conducted under the label of CDA, we shall nevertheless refer to some of these studies below. 2. 1 Gender inequality One vast field of critical research on discourse and language that thus far has not been carried out within a CDA perspective is that of gender. In many ways, feminist Critical Discourse Analysis 359 work has become paradigmatic for much discourse analysis, especially since much of this work explicitly deals with social inequality and domination.We will not review it here; see Kendall and Tannen, this volume; also the books authored and edited by, e. g. , Cameron (1990, 1992); Kotthoff and Wodak (1997); Seidel (1988); Thorne et al. (1983); Wodak (1997); for discussion and comparison with an approach that emphasizes cultural differences rather than power differences and inequality, see, e. g. , Tannen (1994a); see also Tannen (1994) for an analysis of gender differences at work, in which many of the properties of discursive dominance are dealt with. 2. 2 M edia discourseThe undeniable power of the media has inspired many critical studies in many disciplines: linguistics, semiotics, pragmatics, and discourse studies. Traditional, often content analytical approaches in critical media studies have revealed biased, stereotypical, sexist or racist images in texts, illustrations, and photos. Early studies of media language similarly focused on easily observable surface structures, such as the biased or partisan use of words in the description of Us and Them (and Our/Their actions and characteristics), especially along sociopolitical lines in the representation of communists.The critical tone was set by a series of â€Å"Bad News† studies by the Glasgow University Media Group (1976, 1980, 1982, 1985, 1993) on features of TV reporting, such as in the coverage of various issues (e. g. industrial disputes (strikes), the Falklands (Malvinas) war, the media coverage of AIDS. ) Perhaps best known outside of discourse studies is the media re search carried out by Stuart Hall and his associates within the framework of the cultural studies paradigm. (See, e. g. , Hall et al. 1980; for introduction to the critical work of cultural studies, see Agger 1992a; see also Collins et al. 986; for earlier critical approaches to the analysis of media images, see also Davis and Walton 1983; and for a later CDA approach to media studies that is related to the critical approach of cultural studies, see Fairclough 1995b. See also Cotter, this volume. ) An early collection of work of Roger Fowler and his associates (Fowler et al. 1979) also focused on the media. As with many other English and Australian studies in this paradigm, the theoretical framework of Halliday's functional-systemic grammar is used in a study of the â€Å"transitivity† of syntactic patterns of sentences (see Martin, this volume).The point of such research is that events and actions may be described with syntactic variations that are a function of the underlyi ng involvement of actors (e. g. their agency, responsibility, and perspective). Thus, in an analysis of the media accounts of the â€Å"riots† during a minority festival, the responsibility of the authorities and especially of the police in such violence may be systematically de-emphasized by defocusing, e. g. by passive constructions and nominalizations; that is, by leaving agency and responsibility implicit.Fowler's later critical studies of the media continue this tradition, but also pay tribute to the British cultural studies paradigm that defines news not as a reflection of reality, but as a product shaped by political, economic, and cultural forces (Fowler 1991). More than in much other critical work on the media, he also focuses on the linguistic â€Å"tools† for such a critical study, such as the analysis of transitivity in syntax, lexical structure, modality, and speech acts.Similarly van Dijk (1988b) applies a theory of news discourse (van Dijk 1988a) in 360 Teun A. van Dijk critical studies of international news, racism in the press, and the coverage of squatters in Amsterdam. 2. 3 Political discourse Given the role of political discourse in the enactment, reproduction, and legitimization of power and domination, we may also expect many critical discourse studies of political text and talk (see Wilson, this volume).So far most of this work has been carried out by linguists and discourse analysts, because political science is among the few social disciplines in which discourse analysis has remained virtually unknown, although there is some influence of â€Å"postmodern† approaches to discourse (Derian and Shapiro 1989; Fox and Miller 1995), and many studies of political communication and rhetoric overlap with a discourse analytical approach (Nimmo and Sanders 1981).Still closer to discourse analysis is the current approach to â€Å"frames† (conceptual structures or sets of beliefs that organize political thought, policies, and discourse) in the analysis of political text and talk (Gamson 1992). In linguistics, pragmatics, and discourse studies, political discourse has received attention outside the more theoretical mainstream. Seminal work comes from Paul Chilton; see, e. g. , his collection on the language of the nuclear arms debate (Chilton 1985), as well as later work on contemporary nukespeak (Chilton 1988) and metaphor (Chilton 1996; Chilton and Lakoff 1995).Although studies of political discourse in English are internationally best known because of the hegemony of English, much work has been done (often earlier, and often more systematic and explicit) in German, Spanish, and French. This work is too extensive to even begin to review here beyond naming a few influential studies. Germany has a long tradition of political discourse analysis, both (then) in the West (e. g. about Bonn's politicians by Zimmermann 1969), as well as in the former East (e. g. he semiotic-materialist theory of Klaus 1971 ) (see also the introduction by Bachem 1979). This tradition in Germany witnessed a study of the language of war and peace (Pasierbsky 1983) and of speech acts in political discourse (Holly 1990). There is also a strong tradition of studying fascist language and discourse (e. g. the lexicon, propaganda, media, and language politics; Ehlich 1989). In France, the study of political language has a respectable tradition in linguistics and discourse analysis, also because the barrier between (mostly structuralist) inguistic theory and text analysis was never very pronounced. Discourse studies are often corpus-based and there has been a strong tendency toward formal, quantitative, and automatic (content) analysis of such big datasets, often combined with critical ideological analysis (Pecheux 1969, 1982; Guespin 1976). The emphasis on automated analysis usually implies a focus on (easily quantifiable) lexical analyses (see Stubbs, this volume).Critical political discourse studies in Spain and especially also in Latin America has been very productive. Famous is the early critical semiotic (anticolonialist) study of Donald Duck by Dorfman and Mattelart (1972) in Chile. Lavandera et al. (1986, 1987) in Argentina take an influential sociolinguistic approach to political discourse, e. g. its typology of authoritarian discourse. Work of this group has been continued and organized in a more explicit CDA framework especially by Pardo (see, e. g. her work Critical Discourse Analysis 361 on legal discourse; Pardo 1996). In Mexico, a detailed ethnographic discourse analysis of local authority and decision-making was carried out by Sierra (1992). Among the many other critical studies in Latin America, we should mention the extensive work of Teresa CarbO on parliamentary discourse in Mexico, focusing especially on the way delegates speak about native Americans (CarbO 1995), with a study in English on interruptions in these debates (CarbO 1992). . 4 Ethnocentrism, antisemitism, n ationalism, and racism The study of the role of discourse in the enactment and reproduction of ethnic and â€Å"racial† inequality has slowly emerged in CDA. Traditionally, such work focused on ethnocentric and racist representations in the mass media, literature, and film (Dines and Humez 1995; UNESCO 1977; Wilson and Gutierrez 1985; Hartmann and Husband 1974; van Dijk 1991).Such representations continue centuries-old dominant images of the Other in the discourses of European travelers, explorers, merchants, soldiers, philosophers, and historians, among other forms of elite discourse (Barker 1978; Lauren 1988). Fluctuating between the emphasis on exotic difference, on the one hand, and supremacist derogation stressing the Other's intellectual, moral, and biological inferiority, on the other hand, such discourses also influenced public opinion and led to broadly shared social representations.It is the continuity of this sociocultural tradition of negative images about the Oth er that also partly explains the persistence of dominant patterns of representation in contemporary discourse, media, and film (Shohat and Stam 1994). Later discourse studies have gone beyond the more traditional, content analytical analysis of â€Å"images† of the Others, and probed more deeply into the linguistic, semiotic, and other discursive properties of text and talk to and about minorities, immigrants, and Other peoples (for detailed review, see Wodak and Reisigl, this volume).Besides the mass media, advertising, film, and textbooks, which were (and still are) the genres most commonly studied, this newer work also focuses on political discourse, scholarly discourse, everyday conversations, service encounters, talk shows, and a host of other genres. Many studies on ethnic and racial inequality reveal a remarkable similarity among the stereotypes, prejudices, and other forms of verbal derogation across discourse types, media, and national boundaries.For example, in a va st research program carried out at the University of Amsterdam since the early 1980s, we examined how Surinamese, Turks, and Moroccans, and ethnic relations generally, are represented in conversation, everyday stories, news reports, textbooks, parliamentary debates, corporate discourse, and scholarly text and talk (van Dijk 1984, 1987a, 1987b, 1991, 1993). Besides stereotypical topics of difference, deviation, and threat, story structures, conversational features (such as hesitations and repairs in mentioning Others), semantic moves such as disclaimers (â€Å"We have nothing against blacks, but . . . , etc. ), lexical description of Others, and a host of other discourse features also were studied. The aim of these projects was to show how discourse expresses and reproduces underlying social representations of Others in the social and political context. Ter Wal (1997) applies this framework in a detailed study of the ways Italian political and media discourse gradually changed, from an antiracist commitment and benign representation 362 Teun A. van Dijk of the â€Å"extracommunitari† (non-Europeans) to a more stereotypical and negative por- trayal of immigrants in terms of crime, deviance, and threat. The major point f our work is that racism (including antisemitism, xenophobia, and related forms of resentment against â€Å"racially† or ethnically defined Others) is a complex system of social and political inequality that is also reproduced by discourse in general, and by elite discourses in particular (see further references in Wodak and Reisigl, this volume). Instead of further elaborating the complex details of the theoretical relationships between discourse and racism, we shall refer to a book that may be taken as a prototype of conservative elite discourse on â€Å"race† today, namely, The End of Racism by Dinesh D'Souza (1995).This text embodies many of the dominant ideologies in the USA, especially on the right, and it specifically targets one minority group in the USA: African Americans. Space prohibits detailed analysis of this 700-page book (but see van Dijk 1998a). Here we can merely summarize how the CDA of D'Souza's The End of Racism shows what kind of discursive structures, strategies, and moves are deployed in exercising the power of the dominant (white, western, male) group, and how readers are manipulated to form or confirm the social representations that are consistent with a conservative, supremacist ideology.The overall strategy of D'Souza's The End of Racism is the combined implementation, at all levels of the text, of the positive presentation of the in-group and the negative presentation of the out-group. In D'Souza's book, the principal rhetorical means are those of hyperbole and metaphor, viz. , the exaggerated representation of social problems in terms of illness (â€Å"pathologies,† â€Å"virus†), and the emphasis of the contrast between the Civilized and the Barbarians. Seman tically and lexically, the Others are thus associated not simply with difference, but rather with deviance (â€Å"illegitimacy†) and threat (violence, attacks).Argumentative assertions of the depravity of black culture are combined with denials of white deficiencies (racism), with rhetorical mitigation and euphemization of its crimes (colonialism, slavery), and with semantic reversals of blame (blaming the victim). Social conflict is thus cognitively represented and enhanced by polarization, and discursively sustained and reproduced by derogating, demonizing, and excluding the Others from the community of Us, the Civilized. 2. From group domination to professional and institutional power We have reviewed in this section critical studies of the role of discourse in the (re)production inequality. Such studies characteristically exemplify the CDA perspective on power abuse and dominance by specific social groups. ‘ Many other studies, whether under the CDA banner or not, a lso critically examine various genres of institutional and professional discourse, e. g. text and talk in the courtroom (see Shuy, this volume; Danet 1984; O'Barr et al. 978; Bradac et al. 1981; Ng and Bradac 1993; Lakoff 1990; Wodak 1984a; Pardo 1996; Shuy 1992), bureaucratic discourse (Burton and Carlen 1979; Radtke 1981), medical discourse (see Ainsworth-Vaughn and Fleischman, this volume; Davis 1988; Fisher 1995; Fisher and Todd 1986; Mishler 1984; West 1984; Wodak 1996), educational and scholarly discourse (Aronowitz 1988; Critical Discourse Analysis 363 Apple 1979; Bourdieu 1984, 1989; Bernstein 1975, 1990; Bourdieu et al. 1994; Giroux 1981; Willis 1977; Atkinson et al. 995; Coulthard 1994; Duszak 1997; Fisher and Todd 1986; Mercer 1995; Wodak 1996; Bergvall and Remlinger 1996; Ferree and Hall 1996; Jaworski 1983; Leimdorfer 1992; Osler 1994; Said 1979; Smith 1991; van Dijk 1987, 1993), and corporate discourse (see Linde, this volume; Mumby 1988; Boden 1994; Drew and Heritage 1992; Ehlich 1995; Mumby 1993; Mumby and Clair 1997), among many other sets of genres. In all these cases, power and dominance are associated with specific social domains (politics, media, law, education, science, etc. , their professional elites and institutions, and the rules and routines that form the background of the everyday discursive reproduction of power in such domains and institutions. The victims or targets of such power are usually the public or citizens at large, the â€Å"masses,† clients, subjects, the audience, students, and other groups that are dependent on institutional and organizational power. 3 Conclusion We have seen in this chapter that critical discourse analyses deal with the relationship between discourse and power.We have also sketched the complex theoretical framework needed to analyze discourse and power, and provided a glimpse of the many ways in which power and domination are reproduced by text and talk. Yet several methodological and theoreti cal gaps remain. First, the cognitive interface between discourse structures and those of the local and global social context is seldom made explicit, and appears usually only in terms of the notions of knowledge and ideology (van Dijk 1998).Thus, despite a large number of empirical studies on discourse and power, the details of the multidisciplinary theory of CDA that should relate discourse and action with cognition and society are still on the agenda. Second, there is still a gap between more linguistically oriented studies of text and talk and the various approaches in the social. The first often ignore concepts and theories in sociology and political science on power abuse and inequality, whereas the second seldom engage in detailed discourse analysis. Integration of various approaches is therefore very important to arrive at a satisfactory form of multidisciplinary CDA.NOTES I am indebted to Ruth Wodak for her comments on an earlier version of this chapter, and to Laura Pardo for further information, about CDA research in Latin America. 1 It comes as no surprise, then, that CDA research will often refer to the leading social philosophers and social scientists of our time when theorizing these and other fundamental notions. Thus, reference to the leading scholars of the Frankfurter School and to contemporary work by Habermas (for instance, on legitimation and his last â€Å"discourse† approach to norms and democracy) is of course common in critical analysis. Similarly, many critical studies will refer to Foucault 64 Teun A. van Dijk when dealing with notions such as power, domination, and discipline or the more philosophical notion of â€Å"orders of discourse. † More recently, the many studies on language, culture, and society by Bourdieu have become increasingly influential; for instance, his notion of â€Å"habitus. † From another sociological perspective, Giddens's structuration theory is now occasionally mentioned. It should be b orne in mind that although several of these social philosophers and sociologists make extensive use of the notions of language and discourse, they seldom engage in explicit, systematic discourse analysis.Indeed, the last thing critical discourse scholars should do is to uncritically adopt philosophical or sociological ideas about language and discourse that are obviously uninformed by advances in contemporary linguistics and discourse analysis. Rather, the work referred to here is mainly relevant for the use of fundamental concepts about the social order and hence for the metatheory of CDA. 2 Space limitations prevent discussion of a third issue: how dominated groups discursively challenge or resist the control of powerful groups. 3 Note that â€Å"mind control† is merely a handy phrase to summarize a very complex process.Cognitive psychology and mass communication research have shown that influencing the mind is not as straightforward a process as simplistic ideas about mind control might suggest (Britton and Graesser 1996; Glasser and Salmon 1995; Klapper 1960; van Dijk and Kintsch 1983). Recipients may vary in their interpretation and uses of text and talk, also as a function of class, gender, or culture (Liebes and Katz 1990). Likewise, recipients seldom passively accept the intended opinions of specific discourses. However, we should not forget that most of our beliefs about the world are acquired through discourse. In order to analyze the complex processes involved in how discourse may control people's minds, we would need to spell out the detailed mental representations and cognitive operations studied in cognitive science. Since even an adequate summary is beyond the scope of this chapter, we will only briefly introduce a few notions that are necessary to understand the processes of discursive mind control (for details, see, e. g. , Graesser and Bower 1990; van Dijk and Kintsch 1983; van Oostendorp and Zwaan 1994; Weaver et al. 1995). 5 Note tha t the picture just sketched is very schematic and general.The relations between the social power of groups and institutions, on the one hand, and discourse on the other, as well as between discourse and cognition, and cognition and society, are vastly more complex. There are many contradictions. There is not always a clear picture of one dominant group (or class or institution) oppressing another one, controlling all public discourse, and such discourse directly controlling the mind of the dominated. There are many forms of collusion, consensus, legitimation, and even â€Å"joint production† of forms of inequality.Members of dominant groups may become dissidents and side with dominated groups, and vice versa. Opponent discourses may be adopted by dominant groups, whether strategically to neutralize them, or simply because dominant power and ideologies may change, as is for instance quite obvious in ecological discourse and ideology. 6 Unfortunately, the study of the discursiv e reproduction of class has been rather neglected in this perspective; for a related approach, though, see Willis (1977).
