The Integumentary System Essay Example

The Integumentary System Essay 5 The Integumentary System FOCUS: The integumentary system consists of the skin, hair, nails, and a variety of glands. The epidermis of the skin provides protection against abrasion, ultraviolet light, and water loss, and produces vitamin D. The dermis provides structural strength and contains blood vessels involved in temperature regulation. The skin is attached to underlying tissue by the hypodermis, which is a major site of fat storage. CONTENT LEARNING ACTIVITY Hypodermis The hypodermis is not part of the integumentary system. Match these terms with the correct statement or definition: Fat Hypodermis 1. Sometimes called subcutaneous tissue. 2. Loose connective tissue that attaches the skin to underlying bone or muscle. 3. Functions as padding and insulation. 4. Responsible for some of the structural differences between men and women. The hypodermis contains about half the bodys stored fat.

Structures Of Resisitance Essays - Land Management, Feudalism

Structures Of Resisitance Essays - Land Management, Feudalism Structures Of Resisitance The nature of interaction between traditional agrarian society and the modern world has remained a controversial debate amongst anthropologists, sociologists and political theorists. It remains contentious as to whether the dominance of modern values over traditional is desirable; whether the arrival of the market and modern commerce betters or worsens the conditions of rural society and its relationship with the metropol; whether such change is received with apprehension or optimism by the members of rural society. Joel Migdal, for example, puts forth certain arguments proposing the concept of culture contactthat exposure and contact are the causes of change. Migdal identifies three reasons suggesting why such change would be likely to occur: (1) The benefits of the modern far outweigh the benefits of the traditional. (2) The individual is free from severe institutional restraints which would prevent him from making an unimpeded decision. (3) Those individuals who select the new are rational and are optimisers, and those individuals who do not accept the modern fail to do so because of wrong or nonrational values. Most theorists, however, tend to agree that modern society, for good or bad, is clearly encroaching on traditional agrarian society and gradually moulding its values, economic systems and sociopolitical institutions into variants of the modern equivalent. However, this consensus fails to account for one extremely significant fact: that despite the overwhelming economic, political and cultural dominance of the modern world, traditional agrarian structures continue to persist in various forms: the feudal estates of Third World countries, plantations and latifundismos in Southern Italy and much of Latin America, and so on. The questions thus arise: why do such traditional social relations persist in spite of the modern impulse? Why do customs and rituals and social codes play such an important part in determining rural society? Why do inefficient labour-intensive technology and archaic labour organisation systems continue to determine the process of economic production? And why do state attempts at modernising rural production continually face defeat and fail to effect conclusive change? This paper attempts to answer these and other questions through an analysis of two similar anachronistic structures that exist in the contemporary world: the Italian latifondo and the Latin American latifundismo. Both structures are organised in a very similar manner, and an analysis of both presents a holistic picture of their social and economic organisation. The paper begins by describing the administrative structure of the latifondo, and then goes on to suggest that the socioeconomic peculiarities of the enterprise may be at least partially explained by the rational voluntarist behaviour of the landlord, who allows old structures to persist in light of their cultural peculiarity. In The Mafia of a Sicilian Village, Anton Blok describes the Sicilian latifondo as being in its main features involutionary. Blok invokes this term while alluding to a complex process in which certain structures undergo internalisation and fixity, as suggested by Clifford Geertz in Agricultural Involution. Involution, according to Geertz, refers to the overdriving of an established form in such a way that it becomes rigid through an inward elaboration of detail. Bloks study of the latifondo leads him to conclude that this agrarian enterprise underwent such a process at both the social and the economic level. Before further exploring this process, however, it is necessary to first understand the power structure and organisation of the Sicilian latifondo. According to Blok, the latifondo was typically leased out to a gabelloto, who in turn hired a number of permanent employees to manage the enterprise. These administrators generally comprised an overseer (soprastante) and a number of field guards (campieri). The overseer was the gabellotos man of confidence he dealt with the peasants set to work on the estates and took care of the general protection of the enterprise. The campieri assisted the overseer in his work, and constituted a kind of private police force which, in the absence of an efficient formal control apparatus, claimed to maintain law and order in the countryside. This hierarchical structure is replicated in Latin American latifundios, as described by Ernest Feder in Latifundios and Agricultural Labour. Feder further describes the Latin American latifundismo as being characterised by absentee landlordism. He asserts that for the rural worker almost every estate

Cellphones Play Important Roles in Communication

Sex and Violence in Popular Culture Research Paper

Sex and Violence in Popular Culture - Research Paper Example The paper focuses on the influence of popular culture on the controversial societal issues like sex and violence. Before going on the discussion, the terms sex, violence and popular culture will be defined first as the meanings contribute to the understanding of the subject matter. Sex is usually equaled to gender as they are interchangeably used in everyday conversations. In reality, sex and gender are different. The former relates to physiological characteristic as the latter is a social concept. Sex is also an act that shows physical contact for procreation. Gender depends upon sets of social norms affected by culture and tradition that set apart males from females (Wilson 1-2). The other term to define is violence. Violence responds to conflict as harm is afflicted physically, emotionally or mentally on other people as a result of human action. Violence includes social injustices such as racism and poverty (Daoust 290). Both of them are linked to popular culture. Popular culture deals with the everyday living of people as the theme reflects the lives of the common people (Browne 5). The study deals with the negative effects of the prevailing images shown by the popular culture to the increasing cases of sex and violence as the two societal problems occur in the recent years in response to what the majority people believe. As people throughout their lives seek for learning about the world and its meanings, interactions happen as the humans in the society share experiences. People have roles to play in their lives as the society dictates as standards and acceptable behavior. The roles do not have strict and rigid boundaries as people can have various roles that show flexibility. People can take charge of their lives and choose particular roles to play. Play is important in socialization and building of the personalities of people as personalities affect the roles that people play. In terms of personality traits, the gender is also affected. Nowadays the avail ability of television programs and video games are widely used by people for information and relaxation. Such popular media affect the roles of women as the video games portray women maintaining beauty and men protecting women even with the use of violence (Dietz 425-426). The portrayals in videogames become very blatant as more people, the young and the old make use of the high technology games for their relaxation. Video games pose hazards in the view and existence of sex and violence as they portray women as sex objects and men as aggressive in nature. The games also show some gender inequality as women are underrepresented in games according to several video game magazines used in the studies done by Dill and Thill. Both the magazines and the games featured there make use of stereotypes in portraying masculinity and femininity like scanty clothes for female characters and brutal weapons for male characters (Dill and Thill 858-859). Stereotypes generalize the categories for showi ng what men and women must be and what they must be not. In reality, it would be impossible to make use of those stereotypes as people are different from one another. Violence and sex were also seen in a particular videogame called Grand Theft Auto: San Andreas as the protagonist or the controllable in-game character is an African-American who encounters racism, violence, sex and all other societal problems on his way home. Black males were

Summary11 - Essay Example The researchers try their best that there is no negative impact of their entry into their lives so they maintain the confidentiality and the privacy of the participants’ information. The threats to the confidentiality of the data are rare but occur often and therefore, the researchers take every possible precaution to protect the data. At the same time, they maintain agreements with the government agencies such as police, customs and tax agents to thwart any demand for the disclosure of information. Basically, the harm to the participant of the disclosing of the information is greater than the benefits to the society at large and therefore, poses an immense ethical issue for criminologists. Protection of the privacy of the personal information of the participant of the criminologists’ research poses another threat to the ethics of the society. The benefits to the society of the research must be weighed against the harms done by the disclosure of the information. At times, the researchers complain that the privacy law prevents them from the active beneficial research work. The disclosure of the personal information related to homicides, sexual abuses and frauds could jeopardize the safety of the respective participants. Therefore to ensure the safety of these people and the researchers, the reports and all other work related to research was anonymised. Informed consent is another issue that confronts the criminologists. The participants must be provided with the lucid understanding of the research objectives and the consent process so that they are aware of all the possible interactions as well as possible dangers to them. The interests and the freedom of the participants must be protected from the researchers and that informed consent must be taken. The criminologists have the probability and the potential to affect the wellbeing of the participants as well as their future economic interests. These researchers must try to minimize the harm to the

Television watching Essay Example for Free

Television watching Essay Extensive viewing of violent programs on television can lead to aggression in children. Children watch an average of three to four hours a televison a day. Television is a powerful influence in shaping behavior and developing value systems. It may lead to a gradual acceptance of violence, imitation of violence, and the identification of violence within themselves. The more a child views a violent television program the more they will become immune to violence and learn to gradually accept it. Research has shown ideal to be true. One example: in several studies, those who watched a violent program instead of a nonviolent one were slower to intervene or to call for help when, a little later, they saw younger children fighting or playing destructively. (What do) Viewing the violent program caused the child to take more time to react to the situation. He had been desensitized to the violent act because he had been viewing a violent programmed show. Television can cause a child to grow to feel immune towards violence. Perhaps our child in this case simply felt nothing but seeing what he witnessed, or maybe he had accepted it as something normal. In either case the violent programs that children are watching are causing adverse effects. A child who has no been exposed to such violent programming on television would have reacted much quicker and intervened when they saw a younger child fighting. But television doesnt only cause children to become immune to the horror of violence, or to gradually be able to accept it as a part of the world. It also can lead to the imitation of violence from the children. Television violence causes an imitation and a heightened sense of aggression among younger children. This proposes a much more of a problem then simply accepting violence and becoming immune to it. Younger children are more likely to carry out violent acts on other children if they are exposed to a substantial amount of violence on television today. This can cause problems in school, home, and even work environments. The child will come to believe that violence is the answer to his problems. Any act of aggression carried out upon another human being will result in a adverse condition being put upon the person committing the act. A child may feel that they need to lash out again someone who took a toy from them as then seen it done on television. This is where the problem begins to make itself apparent. Children who watch the violent shows, even just funny cartoons, were more likely to hit out at their playmates, argue, disobey class rules, leave tasks unfinished, and were less willing to wait for things than those who watched the nonviolent programs (Children). We can see clearly these children are going to find themselves in a whole lot of trouble and many quicker then they realize. From watching the violent programming on televison they accept it as a solution, and the imitate what it is that they have seen. So its not just the imitation alone that effects the children watching the programming its a series of steps. They gradually accept it, then they imitate it, and in imitating it then learn to identify with it. Identification on violence in televison programming leads to an extended identification of the world, aggression, and themselves. Identification with violence on televison can become the most dangerous relationship between TV and the younger person. Studies by George Gerbner, Ph.D., at the University of Pennsylvania, have shown that childrens TV shows contain about 20 violent acts each hour and also that children who watch a lot of television are more likely to think that the world is a mean and dangerous place (What do..). Believing that the work is a mean and dangerous place can put fear into a child. They have already learned to accept and imitate violence, through identification they may react in a way that fits in with the ideal of mean and dangerous. Also, they may become more aggressive in order to fit in with their perspective of what should be. Drama televison often shows a teen going through many difficult situation in their life. Perhaps the program is about a teen committing suicide as a way to deal and cope with his problems. The young child has already learned to accept this violent act and feel immune to it. He could imitate it, or identify with it. In either case this is where a serious problem can begin to show an ugly head. These situation could perhaps been avoided if less violent programming was viewed, or moderated. The violent acts carried out in children is not simply one of these three factors, but it is a progression of the three. Children can accept the violence, then imitate, and identify with it. One in itself doesnt present as serious as issue as the three combined. Televison programming does indeed  have an adverse relationship with aggression among children. We most come to realize that this relationship is only going to progress and in some cases could even result in the loss of many lives.

A Case of Murder by Vernon Scannel is a poem which deals with a very Es

A Case of Murder by Vernon Scannel is a poem which deals with a very unusual topic; the murder of a cat by a nine year old boy. The poet brings the poem alive by using different writing techniques e.g. line lengths. â€Å"A Case of murder† by Vernon Scannel Critical response to literature by Gregor Baird â€Å"A Case of Murder† by â€Å"Vernon Scannel† is a poem which deals with a very unusual topic; the murder of a cat by a nine year old boy. The poet brings the poem alive by using different writing techniques e.g. line lengths, no rhyme or pattern this holds my attention more and stops the rhyme merge into one tone. He also uses writing techniques such as Repetition, Figurative language, structure & rhyme. In the poem the boy has been left with a cat in a basement flat and the cat is just sitting buzzing away. This really annoys the boy and the hatred that has gathered up in the boy. This results in the boy hitting the cat then prodding the cat then crushing the cat in between the door. In result to this the boy cries and decides to get a shovel from the cupboard under the stairs and he shovels the cat into the cupboard under the stairs. Although the cat is dead he thinks the cat is growing in the cupboard and the cupboard is going to split. The boy in the poem is very annoyed about the cat â€Å"He hated that cat; he watched it sit a buzzing machine of soft black stuff† because the cat gets all the attention and he is left out, therefore the boy is jealous of the cat. From the poem it tells us that the boy is insecure with his parents â€Å"He was only nine, not old enough to be left alone in a basement flat† because they left a nine-year-old alone with a cat in a basement flat with no one. This also tells us that h... ...re isn’t something the poet wants to commit to in this poem. It doesn’t have an order of regular size in each stanza a variety of length of lines. Unclear pattern allows us to see the change in the boy’s emotions. The theme of this poem is all to do with guilt, which has been mentioned in the essay. Hate is the main emotion between boy and cat, conscience a thing, which the boy does have, power that has been swapped from cat to boy and anger which has built up in the boy. In conclusion to this critical response to literature I have 1covered the techniques in the poem, the emotions, the situation between the boy and the cat and the very unusual topic. It has been described how the poet brings the unusual poem alive for us. We have discussed the character and how he changed during the main incident and in depth about the emotion and feeling of the boy.

Candide and Enlightenment

Voltaire’s Candide both supported and challenged traditional enlightenment viewpoints through the use of fictional ‘non-western’ perspectives. Candide mockingly contradicts the typical Enlightenment belief that man is naturally good and can be master over his own destiny (optimism). Candide faces many hardships that are caused by the cruelty of man (such as the war between the Bulgars and Abares, Cunegonde being raped, etc) and events that are beyond his control (the earthquake in Lisbon).Voltaire did not believe that a perfect God (or any God) has to exist; he mocked the idea that the world must be completely good, and he makes fun of this idea throughout Candide. He also makes fun of the philosophers of the time, because the philosophers in the novel talk a lot, do nothing, and solve no problems at all. Candide also makes a mockery of the aristocracy’s notion of superiority by birth. Voltaire also addresses the corruption of the religious figures and the church thus â€Å"destroying and challenging the â€Å"Sacred Circle†. Voltaire’s Candide is the story of one man’s trials and sufferings through life. The main character is Candide. Candide is portrayed as a wanderer. He grew up in the Castle of the Baron of Westphalia, who was his mother’s brother and was taught by, Dr. Pangloss, the greatest philosopher of the whole world. Pangloss taught Candide that everything that happens is for the best. Candide is exiled from the castle because of his love for the Baron’s daughter, Cunegonde. He then sets out to different places in the hope of finding her and achieving total happiness. Candide thought that everything happened for the best because the greatest philosopher taught him that, but everyone around him did not accept that theory. The optimistic Pangloss and Candide, suffer and witness a wide variety of horrors: beating, rapes, robberies, unjust executions, disease,and an earthquake, These things do not serve any apparent greater good, but be a sign of the cruelty and madness of humanity and the lack of sympathy of the natural world. Pangloss manages to find justification for the terrible things in the world, but his arguments are sometimes stupid, for example, when the Anabaptist is about to drown he stops Candide from saving him because he claims that the Bay of Lisbon had been formed specifically for the drowning of the Anabaptist. Other characters, such as the old woman, Martin, and Cacambo, have all reached more pessimistic conclusions about humanity and the world because of past experiences. One problem with Pangloss’ optimism was that it was not based on the real world, but on abstract arguments of philosophy. In the story of Candide, philosophy repeatedly proves to be useless and even destructive. It prevents characters from making realistic judgment of the world around them and from taking positive action to change hostile situations. Candide lies under debris after the Lisbon earthquake and Pangloss ignores his requests for oil and wine and instead struggles to prove the causes of the earthquake. In another scenario, Pangloss is telling Candide of how he contracting venereal disease from Paquette, and how it came from one of Christopher Columbus’ men. He tells Candide that venereal disease was necessary because now Europeans were able to enjoy new world delicacies, like chocolate. The character Candide was the nephew of the Baron of Thunder-ten-tronckh, whose sister, was Candide’s mother. The baron’s sister, refused to marry Candide’s father because he only had seventy-one quarterings (noble lineages) in his coat of arms, while her own coat of arms had seventy-two (Candide, 1). This exaggeration makes the aristocracy’s concern over the subtleties of birth look ridiculous. Candide explores the hypocrisy that was rampant in the Church and the cruelty of the clergy using a variety of satirical and ironic situations such as, the Lisbon earthquake that kills tens of thousands of people and damages three fourth of Lisbon; still the Portuguese Inquisition decides to perform an auto-da-fe’ to appease God and prevent another disaster. This serves no purpose because another earthquake strikes in the middle of the hanging of Pangloss and beating of Candide. Church officials in Candide are portrayed as being among the most sinful of all citizens; having mistresses, engaging in homosexual affairs, and operating as jewel thieves. The most ridiculous example of hypocrisy in the Church is the fact that a Pope has a daughter despite his vows of celibacy. Other examples are the Portuguese Inquisitor, who takes Cunegonde for a mistress, who hangs Pangloss and executes his fellow citizens over philosophical differences, and orders Candide to beaten for, â€Å"listening with an air of approval† (Candide, 13) to the opinions of Pangloss; and a Franciscan friar who is a jewel thief, despite the vow of poverty taken by members of the Franciscan order. Finally, Voltaire introduces a Jesuit colonel with marked homosexual tendenci es. The Enlightenment belief, in which a perfect society should be controlled by reforming existing institutions, is made to appear ridiculous, while erhaps all that Voltaire wanted to do was to present the history of his century with the worst abominations. It was probably Voltaire's ability to challenge all authority that was his greatest contribution to Enlightenment values. He questioned his own parenthood and his morals to express his ideas to the world of Enlightenment through the novel Candide. In particular, the novel makes fun of those who think that human beings can endlessly improve themselves and their environment. Voltaire expresses his beliefs on optimism, philosophical speculation, and religion through the main character. Candide, The main character of the novel, is set adrift in a hostile world and unsuccessfully tries to hold on to his optimistic belief that this â€Å"is the best of all possible worlds† as his tutor, Pangloss, keeps insisting. He travels throughout Europe, South America, and the Middle East, and on the way he encounters many terrible natural disasters. Candide is a good-hearted but hopelessly naive.

Internet a Tool of Modern Age

Mass Media Society Abstract This paper shows the problems of mass media. Mass media is absolutely important for our life. However, as much as mass media plays an important role in our society, it causes some serious problems. Mass media makes citizens recognize misjudgments by distorting the truth. Most serious problem mass media can affect extreme power to our society. Mass media has been developed more and more as society has grown, becoming centralized authority in our society. Exaggerated contents of mass media affect bad sides to people-especially teenagers.Some people tend to believe mass media absolutely, so it is also becomes a problem. Television, internet, and advertising, nowadays, the most important medium of mass media brings some problems to each other, so these are issue in society which people have to solve. Mass Media Power The more society has grown, the bigger the market of mass media has been developed. Hibbert (2006) defined in the book  the power of media  t hat mass media is all part of television, radio, Web sites, newspapers, magazines and books. They deliver information to the public (p. 6).People can meet and understand their society through mass media. Before 1960s, mass media was not public. Some citizens could know how their society and economy were moved according to newspaper. Since 1970s when television was invented, the market of mass media has been developed. Now, most fields of mass media were created, so we can meet mass media really easily not only on the streets but also at home. We are living under the effects of mass media. However, this development of mass media brings some problems in our society as two sides of the same coins.Mass media crisis has rear up secretly because most media organizations do not want to be revealed to their problems frankly. Problems Mass media affects all fields such as politic, economy, government, culture and society. Almost all countries have their own problems of media. The most seriou s problem of that media is mass media can bring confusion of people value. For example, mass media is to make people agree their ideas or thoughts in terms of propaganda. The meaning of propaganda is â€Å"a concerted set of messages aimed at influencing the opinions or behavior of large umbers of people† (Propaganda, 2008). Find out how our expert essay writers can help you with your work†¦ Actually, this word was meaning of the things to be spread. However, now most people may know the word of propaganda is some information which is false or emphasizes one part of a situation, normally used by a government or political group according to Nazi propaganda (Bytwerk, 2005). Taylor (2001) revealed how Hitler implanted his ideology in their citizens: In 1933, Adolf Hitler appointed Minister for Ministry for Public Enlightenment and Propaganda, Joseph Goebbels.Goebbels had spread a lot of propagandas, contained the ideology of Hitler and Nazi. All journalists, writers, and ar tists were needed to register with one of the Ministry's subsidiary chambers for the press, fine arts, music, theater, film, literature, or radio. The Nazis believed in propaganda as a vital tool in achieving their goals. Adolf Hitler was impressed by the power of Allied propaganda during World War I and believed that it had been a primary cause of the collapse of morale and revolts in the German home front and Navy in 1918. Broadcasters and journalists required prior approval before their works were disseminated.Along with posters, the Nazis produced a number of films and books to spread their beliefs. (pp. 162-163) In the U. S. and South Korean government also by emphasizing red complex to their citizens through mass media like radio or newspapers, the governments make their citizens recognize the hostile attitude about all policies of socialism while they justifies their policies (Kang, 1997). These things are absolute examples of mass media’s problem. In addition, as mark et of mass media has been developed much, the authority of mass media has grown also.The power of mass media has been centralized too much, so it exercises extreme influence over any government. The contents of mass media have been contained exaggeration and violence more and more. This mass media makes people tend to believe absolutely. Mass media has strong authority in our society. Mass media became one most important way for people to deliver information since mass media has been developed. We can get a lot of information and knowledge easily through mass media like newspaper, magazines and books. Actually, there is no way for us to take new information except through mass media.Therefore, mass media could have great authority among our society.

Common people may watch television at least one hour every day. Some people usually meet news through television and others may want to watch dramas or variety shows. We can watch a lot of programs according to our tastes through television. Nielsen media research (1998) reported: â€Å"Television was introduced to the U. S. A. t the 1939 World’s Fair in New York. After two years, the Federal communications Commission licensed and approved the first commercially available television stations. In 1950, about 9% of American homes had TV sets. Since 1985, television ownership has been about 98%† (cited in Bushman, 2001, p. 477). Since television was invented, media became very popular in our life. Now almost all families have television at least one at home. Television has developed since 1930th  as amazing invention can give people a lot of information and enjoyment visually and audially both.Most Americans watch television for 3 to 5 hours per day (Horvath, 2004, p. 378). As much as television has become famous to people, it causes many problems too. The violence of television’s programs has very serious effects. In television programs, we can easily see a recurrence of a case. It causes imitative crimes. Brandon Centerwall (1993), a professor at the University of Washington reported that from 1945 to 1974, 93% of the murder rate has been increased. It shows that television teaches violence, and it also makes people be unconcerned about violence.It can also cause antisocial actions. Television can bring addiction, which is one problem appeared since mass media was developed. TV addiction is similar with other addictions like drugs addiction or gambling. Especially TV addiction is bad for children. â€Å"A child who watched two hours of television a day before age three would be 20 percent more likely to have attention problems at age seven compared with a child who did not watch television† (Christakis, 2004). Television programs are contained to the violent acts and sensational contents more and more by pursuing commercial value.Moreover, they also maintain that television is forcing simple thoughts. Television gives us a lot of information but they can just give that. Viewers just can accept television’s information we cannot communicate with television. It is sure that the invention of television brought great development in our society. However, as the market of broadcast has been bigger, programs in television has been contained more violence and exaggerated. These things give children and teenagers bad effects, so all broadcast need to adjust their program contents. Internet Thatcher and Goolam (2005) said in their journal:The number of people using the internet has grown exponentially since the emergence of World Wide Web about ten years ago. No one is exactly sure how many people have online access. According to NUA Internet Survey (2002), it was estimated the number of internet users is approximately 600 million people in 2002 (Nua Internet survey, cited in Thatcher ; Goolam, 2002, p. 767). The popularity of the WWW, combined with the pervasiveness of computer technology in general, means that people are becoming increasingly reliant on technology and the Internet to conduct their day-to-day and work activities. p. 767) Although internet appeared as a new medium of media and it formed new society, internet is not mixed with society where we live, so it caused many problems. We can accept tremendous information via internet because people in all over the world could share their information on network. However, as much as there is a lot of knowledge, in internet there is also information not true and useless. Also, since internet was popularized, many illegal crimes have been happened through internet. These crimes committed through the use of computer are called cybercrime.Cybercrime is â€Å"a real and growing problem that costs governments, businesses, and individual computer users millions of dollars annually and that facilitates many of the same cri mes committed in real space, such as identity theft and the trafficking of child pornography, only on a larger scale† (Jones, 2007). The Internet Crime Complaint Center (IC3) revealed the U. S. A. lost about 240 million dollars from online crime during 2007: Find out how our expert essay writers can help you with your work†¦ Financial losses from online crime reported to U. S. uthorities reached a record high last year, topping nearly 240 million dollar. Taking into account unreported crimes the real figure is likely to be much higher. Auction fraud and other forms of cybercrime reported to the Internet Crime Complaint Center were up 40 million or 20 per cent from those reported in 2006. The IC3 received 206,884 complaints about internet crimes last year, more than 90,000 of which were referred to law enforcement agencies across the U. S. IC3, which serves as a clearing house for cybercrime, is a joint operation between the FBI and the National White Collar Crime Center.A lthough internet auction fraud was the most widely reported complaint to the IC3, other problem areas included non-delivery of purchases and credit card fraud. Computer hacking attacks spam and child abuse on the net formed the subject of other complaints. Commonly reported scams involved the purchase or sale of pets, cheque fraud, email spam, and online dating fraud. The report provides evidence that the U. K. is fast catching up with the U. S. in being a hotbed of cybercrime. Despite the fact that the IC3 study is supposedly a national US annual report, the UK is the source of 15. per cent of the crime reports, significantly ahead of other cybercrime hotspots such as Nigeria (Leyden, 2008). It is also commonly happened to be invaded person’s privacy and personal information on network. According to a survey of 1,000 U. S. adults conducted by TNS Sofres on behalf of digital-security company Gemalto (2008), about 60% of Americans are concerned about stealing their account pas swords when they bank online, and 38% do not believe online payments (cited in Swartz, 2008). Advertising Advertising is a part of mass media.Market of advertisement has been developed as much as we can see an advertisement per one minute. Nowadays most products make up of advertisement because each product has to be sold in infinity competition society. Now customers live in the flood of advertising. From the moment of opening eyes to going to bed, people are connected with advertising through television, radio, newspapers, magazines and catalogs. Human Communication research (1998) shows one adult can contact to 3,000 advertising during one day and he or she can memorize just 10 out of 3,000 (cited in Kim, 2000, p. 4). The market of advertisements has been developed. However, the problem of advertisements are inherent in function of information, entertain and persuasion, so they may not only make people’s life style changed but also promote decadent culture like alcohol, ci garette and sex. You can get expert help with your essays right now. Find out more†¦ Ellickson et al (2005) studied about how much advertising will affect to adolescents: Ellickson and other authors examine the relationship exposure to different forms of alcohol advertisingand subsequent drinking among U.S. adolescents and assess whether exposure to an alcohol and drug prevention program mitigates any such relationship. The sample includes 3111 seventh-graders drawn from 41 South Dakota middle schools, and they are exposed to television beer advertising, variables were constructed for four types of alcohol advertising – television, in – store displays, magazines and concession stands. The result of this experience is several forms of alcohol advertising predict adolescent drinking; which sources dominate depends on the child's prior experience with alcohol.Forty-eight percent of the non-drinkers in grade 7 qualified as past-year drinkers by the spring of ninth gra de, indicating a substantial amount of initiation over the period examined. (pp. 235-246). Like this, advertising affects to people, especially adolescents a lot. Actually advertising has a great of influence on customers and society. For example, there is a study that skinny models in advertising cause eating disorder of women and girl, so some countries took measures to ban ultra-skinny models from their catwalks (Diderich, 2007).People can meet the extreme number of advertising everyday, so advertising has to be made without exaggeration and fiction. Janese Heavin (2007) who is the Tribune’s staff, wrote the article about a study: University of Missouri-Columbia research said that looking at pictures of flawless models in fashion magazines can make even the prettiest women feel downright crummy. Laurie Mintz, associate professor of education, school and counseling psychology in the MU College of Education said most women know intuitively or subconsciously that when they lo ok at magazines they will feel badly about themselves.The study validates what women know in their own experiences but assume it is just theirs to deal with. Spearheaded by graduate student Emily Hamilton, who used the project to earn her master’s degree, the study asked 81 college women to rate how they feel about their appearance, from facial features to chest size. Some of the women were then asked to view magazine advertisements that used fashion models to sell products. Others looked at ads that showed products with no models.Those who saw the images of fashion models later reported having a more negative body image, regardless of their own attractiveness. This study shows women were equally affected by the images. It is been commonly believed that larger women or women struggling with eating disorders feel worse after seeing pictures of models, but the latest study indicates the images are bad for everyone. In conclusion, people have to be careful when accepting mass me dia’s information.There are not simple solutions to solve the problem of media. These problems of mass media like television, internet and advertising have bad effects on people especially the perfection of self during childhood. People should try to accept right information through mass media. Therefore, they need to improve critical thoughts for filtering correct acknowledge. Critical thinking might be helpful to accept which information is needed to us. Critical thinking is â€Å"mental processes of distinguish, analysis and evaluation.Critical thinking is a form of judgment, specifically meaningful and reflective judgment. Using critical thinking one makes a decision or solves the problem of judging what to believe or what to do, but does so in a reflective way† (Critical thinking, 2008). People have the right to criticize and punish media which is to destroy our emotion and ethics. People have to improve power of judgment. If people have ability to control informa tion in this information-oriented society, they may have precedence over other people who do not have.Need an essay? You can  buy essay help  from us today!

Essay Sample on African Americans in Interracial Partnerships

Essay Sample on African Americans in Interracial Partnerships Free sample essay on African Americans: In this essay I will examine partnerships involving African Americans and persons of a different race by using the following question: How are African Americans represented through television and movies as members of an interracial relationships and what traits are being passed on to the next generation of viewers? The first interracial partnership that I examined was that of Claudette and Vic from the television series, The Shield. In the three episodes I viewed from season two, there was a huge underlying conflict between Claudette and Vic (Williams-Hawkins Video Archive, Tape #B-010). Claudette seems inherently suspicious of Vic due to his ambiguity and his past record. Claudette, an African American female and the leader of the precinct is portrayed as a true team-leader, demanding, but still polite about it. She also interacts with Captain Aceveda, a Latino, on a regular basis, working side by side with him. Aceveda was also very suspicious of Vic. Joe Clark, a black man who was Vics training officer, but was later kicked off the force, was somewhat on the other side of the spectrum from Claudette. Joe was originally asked advice by Vic, but then tries to get Vic to participate in a revenge scheme against the man who had him kicked off the force. Through Claudette and Joe we see that Afric an Americans in The Shield are represented mostly as good partners, whether they are good people or not, thats a whole different question (Williams-Hawkins Video Archive, Tape# B-002). The second interracial partnership I examined was that of Lieutenant Fancy and Detective Sipowicz on the police drama NYPD Blue. Sipowicz always appears to be very suspicious of the African American witnesses, and is sometimes rude or racist towards his boss, Lieutenant Fancy, especially while arguing with him. Fancy is an upstanding man, always quick to think of the team before himself, whether with Sipowicz or another member of the precinct he always seems to get along all right. Sipowicz and Fancy work together well when they are not arguing. With Fancy and Sipowicz there is an unspoken bond, despite Sipowiczs somewhat hidden racism, Fancy knows that Sipowicz will always have his back and vice versa (Williams-Hawkins Video Archive, A-118). The third partnership I examined was that of Jackie Chan and Chris Tucker in the movies Rush Hour and Rush Hour 2. Detective Carter is assigned to watch over Inspector Lee during an investigation in Rush Hour. The FBI gives Carter, an over-zealous, loud-mouthed, arrogant detective, a job to keep him out of the way. Carter is very dismissing with his Asian counterpart, Inspector Lee. He is also seen as a joke by his entire department. Carter evolves through this movie from an exact personification of the coon stereotype into more of a cooperative, nice guy who just happens to have a big mouth (Granger, 1998). In Rush Hour 2, the same humor is used in a separate country, this time Carter travels to Hong Kong, where Inspector Lee lives and works. Lee now becomes the more bossy of the two because he his more familiar with Hong Kong than Carter. Carter then reverts to his old tactics of yelling and arrogance only to find his efforts futile in the new environment (Granger, 2001). Carter is a much exaggerated character matching up almost perfectly with the classic stereotype of a coon. In 2000, 166 college students (43% male and 53% female)were surveyed. The students averaged 9.96 hours per week of television viewing. The respondents were told to write down and rate the characteristics of people they saw on TV. They were told to do this entirely from memory. Of the 166 students, all of them listed more negative qualities for African American characters than for white characters. African Americans were seen to have more drug dealing, crime, violence and alcohol abuse problems than whites. They were also perceived as less intelligent, lazier, less tolerant, and less patriotic. The fact is that every college student surveyed saw more negative attributes than positive attributes in the African American characters (Fujioka, 2000). The primary objective of the mass media, film and television in particular, is to hide discoveries like this insisting that races are naturally different and each race is consistent (Rocchio, 2000). Despite those statistics, several advances in the way the African American is portrayed have happened. Due to Spike Lees success in the 1990s more accurate portrayals of African Americans have hit mainstream (Bogle, 1994). When a segment of the general audience responded to [Spike Lees] films, [it looked as if movies by black directors with cultural traits and distinctions] would reach a white audience just as popular music by black artists had reached white music listeners (Bogle, 1994). In response to the question: How are African Americans represented through television and movies as members of an interracial relationships and what traits are being passed on to the next generation of viewers? Despite the fact that African Americans are usually portrayed as assertive and demanding within partnerships, they are still represented as good partners in television and in movies. Whether their antics lead to the capture of someone or the just lead to an entertaining movie, they are portrayed as good partners with open minds and are not portrayed as racist against people from a different ethnic background.

Discussion and Analysis Vardiman, Houghston & Jinkerson (2006) defined leadership as the juxtaposition of skill, communication ability, influencing characteristic and attitude which can be used by a particular organizational individual to influence subordinates. Vardiman, Houghston and Jinkerson (2006) argued that position based power to direct action of others should not be perceived as leadership rather leadership is defined by the behavior, interpersonal skill, attitude of a very individual which make him or her leader. Alas, Tafel & Tuulik (2007) also found that leadership depends heavily on personal traits like relationship with subordinates, collaborative attitude, coordination skill; personality etc and leaders need to have these characteristics in order to influence or motivate subordinates to achieve performance objectives. Now the question is whether workplace supe

Electricty Grid retailer - Assignment Example 4). Increase the ease and reduce the cost to operate PHEV. Electrical Power: How the Electricity Retailer Can Reduce Consumption During Peak Periods with Low Carbon Footprint Energy Technology Electricity is a secondary source of energy. Electricity is transformed from the combustion of coal and fossil fuels into a secondary source, which can be used and effectively and efficiently transmitted by means of power transmission lines to the consumer. Electricity can also be generated by means of the combustion of biomass. Other primary sources from which electricity is transformed are: natural gas, solar, hydro, geothermal, wind and nuclear sources. The electricity which is generated from the combustion of coal, natural gas, fossil fuels and nuclear sources is non renewable. Electricity is also generated from renewable sources such as: hydropower, wind, biomass, geothermal and solar (Need.org n.d.). The cost of generating electricity varies between 2.2 pence per kilowatt hour to 3.2 penc e per kilowatt hour for the electricity producer. The least expensive means of deriving electrical power is from a combined cycle gas turbine. The most expensive means of deriving electrical energy through combustion is the coal fired integrated gasification combined cycle plant. Open cycle gas turbines which operate on the combustion of natural gas are the most well suited for new electrical generating facilities. The best candidates for fulfilling electrical power generation requisites at peak duty are the open cycle gas turbines. These open cycle gas turbines are adaptive, reliable and are capable of being efficiently ignited when the demand for electricity reaches its peak demand. An open cycle gas turbine can generate electricity at 3.2 pence per kilowatt hour when operate continuously. When operated solely at periods of peak duty, the open cycle gas turbine generates electrical energy at 6.2 pence per kilowatt hour (Royal Academy of Engineering n.d.). The operating cost of ren ewable energy sources is more expensive than the constant cycle gas turbine, the pulverized fuel steam facility, the circulated fluidized bed steam plant and the integrated gasification combined cycle. Fluctuation of electrical power generation in the renewable energy sources is a limiting factor in the output generation of electrical power. The cost of generation of electrical power varies from 3.2 pence per kilowatt hour to 7.2 pence per kilowatt hour. The cost of generating electrical power is diminished when there is no standby generation from non renewable sources. An onshore wind farm generates electrical energy at a cost of 3.2 pence per kilowatt hour, notwithstanding the standby generation of electrical power from non renewable sources. In the provision of a standby electrical generator operating from non renewable sources, the cost of generating electricity from an onshore wind farm is 5.4 pence per kilowatt hour. The kilowatt hour cost of generating electrical power from w ave and marine technologies is consistent at 6.6 pence per kilowatt hour, with or without a standby electrical generation resource (Royal Academy of Engineering n.d.). The analysis of consumer demand for electrical energy by the electricity retailer requires constant demand data on a monthly, daily and hourly basis. This data may be evaluated by two means: daily and by the maximum or minimum electrical power consumption. The patterns of demand
