Understanding Society Through Cultural Artifacts

Understanding Society Through Cultural Artifacts Researchers can learn a great deal about a society by analyzing cultural artifacts such as newspapers, magazines, television programs, or music. These cultural artifacts, which can also be considered aspects of material culture, can reveal a great deal about the society that produced them. Sociologists call the study of these cultural artifacts content analysis. Researchers who use content analysis are not studying the people, but rather are studying the communications the people produce as a way of creating a picture of their society. Key Takeaways: Content Analysis In content analysis, researchers examine a societys cultural artifacts in order to understand that society.Cultural artifacts are the aspects of material culture produced by a society, such as books, magazines, televisions shows, and movies.Content analysis is limited by the fact that it can only tell us what content a culture has produced, not how members of the society actually feel about those artifacts. Content analysis is frequently used to measure cultural change and to study different aspects of culture. Sociologists also use it as an indirect way to determine how social groups are perceived. For example, they might examine how African Americans are depicted in television shows or how women are depicted in advertisements. Content analysis can uncover evidence of racism and sexism in society. For example, in one study, researchers looked at the representation of female characters in 700 different films. They found that only about 30% of characters with a speaking role were female, which demonstrates a lack of representation of female characters. The study also found that people of color and LGBT individuals were underrepresented in film. In other words, by collecting data from cultural artifacts, researchers were able to determine the extent of the diversity problem in Hollywood. In conducting a content analysis, researchers quantify and analyze the presence, meanings, and relationships of words and concepts within the cultural artifacts they are studying. They then make inferences about the messages within the artifacts and about the culture they are studying. At its most basic, content analysis is a statistical exercise that involves categorizing some aspect of behavior and counting the number of times such behavior occurs. For example, a researcher might count the number of minutes that men and women appear on screen in a television show and make comparisons. This allows us to paint a picture of the patterns of behavior that underlie social interactions portrayed in the media. Strengths of Using Content Analysis Content analysis has several strengths as a research method. First, it is a great method because it is unobtrusive. That is, it has no effect on the person being studied since the cultural artifact has already been produced. Second, it is relatively easy to gain access to the media source or publication the researcher wishes to study. Rather than trying to recruit research participants to fill out questionnaires, the researcher can use cultural artifacts that have already been created. Finally, content analysis can present an objective account of events, themes, and issues that might not be immediately apparent to a reader, viewer, or general consumer. By conducting a quantitative analysis of a large number of cultural artifacts, researchers can uncover patterns that might not be noticeable from looking at only one or two examples of cultural artifacts. Weaknesses of Using Content Analysis Content analysis also has several weaknesses as a research method. First, it is limited in what it can study. Since it is based only on mass communication – either visual, oral, or written – it cannot tell us what people really think about these images or whether they affect people’s behavior. Second, content analysis may not be as objective as it claims since the researcher must select and record data accurately. In some cases, the researcher must make choices about how to interpret or categorize particular forms of behavior and other researchers may interpret it differently. A final weakness of content analysis is that it can be time consuming, as researchers need to sort through large numbers of cultural artifacts in order to draw conclusions.

Madatory labeling In Resturants - Essay Example This could be in terms of ingredients that are not fit for their consumption and processes used for production that are not of expected standards. (Elise Golan) The reasons for supporting mandatory labeling of foods have to do with the effects of genetically modified food on the health of individuals. The second reason has to do with the ingredients used in the production of the foods. (IFPRI) Some people may be on certain diets that do not allow them to consume the products. The third reason is basically for the benefit of the manufacturing company such that consumers prefer foods from certain companies because of their reputation, labeling makes them easily identifiable to the consumer. Lastly labeling is important for a country as it helps it in identifying products that come from countries that are known to violate manufacturing standards and therefore they do not allow them in the market to protect its citizens. It also enhances fair competition and market efficiency in a given country. (Elise Golan) Consumer choices may change due to mandatory labeling because they are able to identify products that have been certified as fit for use and those that have not. If for example the product is certified by an international accredited body, chances are consumers will buy it more as compared to another labeled by a local body. Consumer preferences in terms of quality will also make certain products to lose market as a result of these as they will be able to differentiate easily and make choices whether to buy or not.

Effects of Modern-Day Fascination with Celebrities Essay

Effects of Modern-Day Fascination with Celebrities - Essay Example To be more precise, celebrities make the society to throw away the cultural makeup. Hence, the community members put on a fake image that does not depict their own characters. Technology is the primary cause of these entire obsessions with celebrities. Teens glue themselves to the television; watching programs that makes them more interested in the lives of celebrities more than their own. Smartphones, on the other hand, provide updates about celebrities’ gossips every hour. Just to remember, the past week, everyone talk was all about the revealed story of Solange, Beyonce’s sister attacking Jay-Z while in an elevator (Sarah, 2014). Thus, the society read about it in the magazine, searched it on the internet, or heard it from friends. Most people obsession with celebrities can lead to cultural paradigm alterations. To some extent, the adjustments are real. A good example is of Michael Sam, the footballer who came out building the confidence of most of the young gay athl etes. He advanced the advocacy for gay marriages and promoted free to talk about their sexuality. On its negative side, the culture of celebrities and fascination with status and wealth make the average and poor people feel unworthy of the world. As a result, the mind of the young people growing up to find a place in the world is corrupted with no option but to become rich even through violence. In fact, some researchers claimed the existence of a growing disorder known as â€Å"Celebrity Worship Syndrome.† The disease is however not inclusive of personality disorder (Inglis, 2010).

Negligence of Tort Essay Example for Free

Negligence of Tort Essay DEFINITIONS: In common law jurisdictions, tort is a civil wrong although in certain circumstances it is also treated as a criminal case e.g. in cases of assault. It is recognized legally as a basis for an action of a lawsuit. TORT: In common law jurisdictions, tort is a civil wrong although in certain circumstances it is also treated as a criminal case e.g. in cases of assault. It is recognized legally as a basis for an action of a lawsuit. Torts are considered under the law of obligations. Duties imposed under tort law are considered mandatory for all citizens unlike voluntary obligations imposed under contracts. If a person commits a tortuous act, he/ she are legally a Tortfeasor. Tortiuos acts include breach of duties imposed under statutory laws, causing bodily harm to other people, property, or infringing on another’s legal rights.for there to be a case under tort NEGLIGENCE: This is a legal concept that is usually used to acquire compensation for injuries suffered or accidents met. It is a civil wrong actionable under tort law. Negligence involves behaving in a manner that lacks the legality of protecting other people against foreseeable risks. Under common law for there to be a case under negligence then the following elements must be satisfied. * Duty of care * Breach of the duty EXAMPLES: Experience Of Harm Arising From That Breach. Donoghue V. Stevenson A case of tort on negligence is only successful if the following five elements are met. Firstly, a duty of care must be evident. Donoghue v. Stevenson. Given this fact, we also need to know whether the consequences of  the defendants act were reasonably foreseen. In case of the family friendly fishing company and Neil, they are legally liable for the immediate harm caused to June and Gina. Kent v Griffiths In the case of jack versus the Gosford hospital, jack has no legal case against the hospital since the emergency landing that arose was not reasonably foreseen. Topp v London Country Bus Ltd In addition to this, Gina and June have a legal case against the family friendly fishing company since there was legal proximity of relationship through the contract of hiring the boat. Home Office v Dorset Yacht Club June and Gina have action against Neil and the family friendly fishing. This is because the company and Neil are professionals in this field and yet they breached the duty they are entailed to do. Bolam v Friern Barnet Hospital June has no case against Grosford hospital since the process through which she lost her arm is normal since it does happen. In addition, the hospital done the best it could to help her and thus they cannot be accused of negligence. The Mickey family and the Grosford hospital could all sue the family friendly fishing for damages. However in mitigation the company could claim that there were multiple causes for the injuries suffered, Wilsher v Essex AHA On the issue of Gina and June the company could claim that the presence of the rare fish on the new south Wales coast was not a common thing and thus the fish could be a contributory factor for June and Gina’s accident. On the issue of the Grosford hospital, the family friendly fishing could claim that the helicopter taking an emergency landing could have been a contributory factor to factor to Junes loss of her hand. Jack may have a legally binding case against the Grosford hospital. Although this is, the case jack would end up losing at the end. This is because firstly there was no relationship of proximity either legal or  physical between the incidents that triggered his condition. Caparo v Dickman .In addition, the hospital could claim vicarious liability since at the time of the incident the hospital was on an external mission at the request of the family friendly fishing company. Although Neil is liable for June and Gina’s initial accidents he is well protected by law. Although June and Gina have a case against Neil, Neil could claim protection under the vicarious liability clause. The vicarious liability refers to the notion that a person can and do become responsible or liable for other people’s liabilities because there exist a legally acceptable relationship. Such relationships might include parent-child relationship, or an employer-employee relationship. In this case, the family friendly fishing could be held liable for Neils liabilities since they are the employers. Between the concerned parties, the most liable party is the family friendly fishing company. This is because all the parties concerned in the melee can all sue the family friendly fishing company. This is because the company’s negligent actions are the reason why each involved party is at a loss. The company should prepare itself for lawsuit and the family friendly fishing company should brace itself, to be legally prepared to pay special damages, general damages as well as punitive damages. On top of this, the company should also be prepared for the courts to issue an injunction against them if it is deemed necessary. CONCLUSION: The five elements of negligence should be recognizable under tort law. However, as professor Robertson of Texas University has noted the five elements needs to be kept separate, this is because in practice there arises lots of conceptual mistakes or confusions. The use of vicarious liability as a defense against a case of law on tort of negligence has widely been disputed over its rationale. Many scholars have argued that the use of vicarious liability is only intended to find legally  a more solvent defendant. In a legal perspective, the family friendly fishing company is supposed to pay special and general damages to Gina and June. This is because the company has caused the two irreparable damage because of its own negligent activities. Damages awarded are usually compensatory but not punitive in nature. For the sake of the family friendly fishing company, the damages it would have to pay would most probably include a punitive element. The punitive element would arise if the employee, Neil would declare that indeed he had asked the company to change the boats gear, although the company declined. This refusal of the company to use standard tools for profiteering reasons would be termed as an act of maliciousness or acting in an callously indifferent way.

Pete Sampras Essay -- essays research papers fc

Pete Sampras the American Sensation The reason why I chose to do my research paper on Pete Sampras is because I love to play tennis, and Pete is the greatest tennis player alive. I have always made him my role model, and I hope to one day meet him. I try and model my tennis game after his and it has really helped my tennis game. Pete Sampras is my childhood hero, and that is the reason why I chose the topic of Pete Sampras. Pete was born on August 12, 1971. in Washington, DC. Although Pete was born in Washington, he grew up in Palos Verdes, California. Pete is a direct descendent of Sam and Georgia Sampras. Pete has three Siblings one elder and two younger. The elder sibling is Stella, the current head tennis coach at UCLA. Pete's younger sister Marion has not decided on a career yet, and Pete's third sibling is his only brother, Gus who is the Current Assistant Tournament Director at Scottsdale ATP Tour Event (Role Models). Pete began playing tennis at the age of seven, and when he was nine, his father asked Pete Fischer, a physician and amateur player, to hit with his son. Fischer was so impressed with Pete's ability, he became Pete's personal coach. When Pete was eleven, he had the opportunity to hit with his childhood hero Rod Laver. Pete later told his coach that he was so nervous he couldn't get the ball over the net. Pete rarely won a major junior tournament. Fischer believed that someone of his talent should play up in age groups against older and stronger players to develop his all around game. When Pete reached the age of 14, Fischer changed Pete's two-handed backhand to a one-handed. At the same time of his backhand switch Fischer switched Pete from a safe defensive baseliner to a risky serve and volleyer. The reason he did this was to try and make Pete feel much more laid back and in the end it worked. Pete turned pro at the age of 16 following his junior year in high-school. By the late 1980's, Pete split with his coach Pete Fischer because Pete felt that Fischer was an overbearing perfectionist. After the split with Fischer, Pete picked up a new coach, Tim Gullikson. Tim Gullikson showed Pete the value of playing percentage tennis--going for smart, conservative shots rather than flashy, difficult ones. On May 3, 1996, Gullik... ...aw: 96 R128 Bye, () N/A R64 Kiefer, Nicolas (GER ) 36 6-3 3-6 6-3 R32 Roddick, Andy (USA ) 131 6-7(2) 3-6 (S.L. Price) As you can see Pete has had a few wins but about two years ago, the peak of his career, he wouldn't have lost to any of those players. If you noticed in the Miami Ericsson open he was beat by Andy Roddick a young 19 year old player who just turned pro. That just reinstates my point that he will not be able to keep up with the young up and comers. WORKS CITED 1.

Coffee Industry Essay

People usually drink coffee to stay up while awake at night, besides that many people rely on coffee to get their day started. According to the New England Journal of Medicine, â€Å"Drinking coffee can lead to a longer life†; however, many consumers have no idea of the impact of habits on their coffee and coffee farmers around the globe, ethical issues of consumers with the industry is not fair; but to coffee farmers, the issues are human rights violations and use of child labor issues need to be addressed. To remedy this situation, the fair trade will hopefully improve the living conditions of some of the poorest people in the world through certified value and the change in the consumer’s choice. Coffee is one of the most valuable commodities in the world, most of the farmers in the form of small retail and come from developing countries, although the majority of coffee sales are in the America and Europe many people around the world rely on coffee to work and have a better life; however, to producing quality coffee, farmers have to work very hard though farmers receive very little money and the inequity of the coffee producing companies when they sell coffee. Working conditions of farmers in the plantations are very different, although they work hard , but it paid for exploitation, for example , in Guatemala , coffee pickers to harvest 100 pounds to get the minimum wage $ 3 per day (The Problem with Fair Trade Coffee 2010),farmers have to work overtime and do not earn extra money, so farmers use child labor for the production of coffee to save money and use these chemicals effect of the human body in order for a fast development of coffee sale on the market. Moreover, using the chemicals and the development of the coffee industry adversely affect habitat and species decline. In addition, forests are cut down to coffee production affects the environment and soil erosion. According to World Wildlife Fund (WWF), â€Å"converting forest to tea and coffee agriculture can also create erosion and soil loss† (WWF 2010) ; yet the farmers have no choice and/or the opportunity to change. According to the International Coffee Organization or ICO â€Å"Coffee production in 2012 was 144 611 000 bags, mostly from less developed countries such as, Brazil 50 826 000 bags. Vietnam 22 000 000 bags and Indonesia 12 730 000 bags â€Å" (ICO 2013), though coffee production is highly ranked in the world, but farmers still do not get enough money to pay for life, for example, Vietnam in 2012, producing nearly 30 % of world coffee production but the turnover is only 10 % of the total trade value obtained from the global industry, the main reason is due to their ability to improve processing of value and coffee products are limited, coffee roasting plants in countries with rates lower than 10%, when farmers sells 1kg of coffee beans, farmers gets about 2 dollars or an average price of one cup of coffee oversea, yet 1 kg of coffee can make 50 cups. In addition, the links between farmers and enterprises are not strong, the lack of information on farmers markets, so farmers often extorted. Moreover, the risk of crop failure is the fear of the coffee growers. Most of the profits from coffee for export processing enterprises, coffee farmers only enjoy a small percentage. That has caused insecurity for farmers. Solution to this problem is the fair trade. According to Wikimedia, Fair trade coffee is coffee that is certified as having been produced and marketed to a stated set of standards. Many Customers pay a higher price when buying coffee with the certification logo or brand in the Belief Furniture , by doing so, they are helping farmers in the Third World . In particular, the fair trade coffee movement gives a reasonable price to the Farmers who were being a low – wage labor exploitation. However, achieve certification of fair trade, farmers must meet several conditions of production as farmers have to meet a large variety of production standards : there are limits on the use of child labor , pesticides , herbicides , genetically modified products , etc. With these standards met, both consumers and farmers can benefit, with farmers getting the sufficient amount of money for their products, and the consumers getting their product knowing it’s safe to consume and has no effect on the producers financially or ethnically. These farmers must cooperate with businesses to produce the certified products, such amounts received will be higher and the lives of the farmers would be better. In addition, consumers should choose certified products in the supermarket or the market as this will support and will be helpful for farmers. In conclusion, fair trading is the way for farmers and coffee producers to get a higher amount, and will change lives for the better. Therefore farmers should choose fair trade to ensure benefits and consumers should choose products that have been certified to support the farmers.
