Three Major Perspectives in Sociology Essay

Three Major Perspectives in Sociology Sociologists analyze social phenomena at different levels and from different perspectives. From concrete interpretations to sweeping generalizations of society and social behavior, sociologists study everything from specific events (the microlevel of analysis of small social patterns) to the â€Å"big picture† (the macro level of analysis of large social patterns). The pioneering European sociologists, however, also offered a broad conceptualization of the fundamentals of society and its workings. Their views form the basis for today’s theoretical perspectives, or paradigms, which provide sociologists with an orienting framework—a philosophical position—for asking certain kinds of questions about society and its people. Sociologists today employ three primary theoretical perspectives: the symbolic interactionist perspective, the functionalist perspective, and the conflict perspective. These perspectives offer sociologists theoretical paradigms for explaining how society influences people, and vice versa. Each perspective uniquely conceptualizes society, social forces, and human behavior (see Table 1). Read more: Functionalist Conflict and Interactionist Perspectives The symbolic interactionist perspective The symbolic interactionist perspective, also known as symbolic interactionism, directs sociologists to consider the symbols and details of everyday life, what these symbols mean, and how people interact with each other. Although symbolic interactionism traces its origins to Max Weber’s assertion that individuals act according to their interpretation of the meaning of their world, the American philosopher George H. Mead (1863–1931) introduced this perspective to American sociology in the 1920s. According to the symbolic interactionist perspective, people attach meanings to symbols, and then they act according to their subjective interpretation of these symbols. Verbal conversations, in which spoken words serve as the predominant symbols, make this subjective interpretation especially evident. The words have a certain meaning for the â€Å"sender,† and, during effective communication, they hopefully have the same meaning for the â€Å"receiver.† In other terms, words are not static â€Å"things†; they require intention and interpretation. Conversation is an interaction of symbols between individuals who constantly interpret the world around them. Of course, anything can serve as a symbol as long as it refers to something beyond itself. Written music serves as an example. The black dots and lines become more than mere marks on the page; they refer to notes organized in such a way as to make musical sense. Thus, symbolic interactionists give serious thought to how people act, and then seek to determine what meanings individuals assign to their own actions and symbols, as well as to those of others. Consider applying symbolic interactionism to the American institution of marriage. Symbols may include wedding bands, vows of life†long commitment, a white bridal dress, a wedding cake, a Church ceremony, and flowers and music. American society attaches general meanings to these symbols, but individuals also maintain their own perceptions of what these and other symbols mean. For example, one of the spouses may see their circular wedding rings as symbolizing â€Å"never ending love,† while the other may see them as a mere financial expense. Much faulty communication can result from differences in the perception of the same events and symbols. Critics claim that symbolic interactionism neglects the macro level of social interpretation—the â€Å"big picture.† In other words, symbolic interactionists may miss the larger issues of society by focusing too closely on the â€Å"trees† (for example, the size of the diamond in the wedding ring) rather than the â€Å"forest† (for example, the quality of the marriage). The perspective also receives criticism for slighting the influence of social forces and institutions on individual interactions. The functionalist perspective According to the functionalist perspective, also called functionalism, each aspect of society is interdependent and contributes to society’s functioning as a whole. The government, or state, provides education for the children of the family, which in turn pays taxes on which the state depends to keep itself running. That is, the family is dependent upon the school to help children grow up to have good jobs so that they can raise and support their own families. In the process, the children become law†abiding, taxpaying citizens, who in turn support the state. If all goes well, the parts of society produce order, stability, and productivity. If all does not go well, the parts of society then must adapt to recapture a new order, stability, and productivity. For example, during a financial recession with its high rates of unemployment and inflation, social programs are trimmed or cut. Schools offer fewer programs. Families tighten their budgets. And a new social order, stability, and productivity occur. Functionalists believe that society is held together by social consensus, or cohesion, in which members of the society agree upon, and work together to achieve, what is best for society as a whole. Emile Durkheim suggested that social consensus takes one of two forms: Mechanical solidarity is a form of social cohesion that arises when people in a society maintain similar values and beliefs and engage in similar types of work. Mechanical solidarity most commonly occurs in traditional, simple societies such as those in which everyone herds cattle or farms. Amish society exemplifies mechanical solidarity. In contrast, organic solidarity is a form of social cohesion that arises when the people in a society are interdependent, but hold to varying values and beliefs and engage in varying types of work. Organic solidarity most commonly occurs in industrialized, complex societies such those in large American cities like New York in the 2000s. The functionalist perspective achieved its greatest popularity among American sociologists in the 1940s and 1950s. While European functionalists originally focused on explaining the inner workings of social order, American functionalists focused on discovering the functions of human behavior. Among these American functionalist sociologists is Robert Merton (b. 1910), who divides human functions into two types: manifest functions are intentional and obvious, while latent functions are unintentional and not obvious. The manifest function of attending a church or synagogue, for instance, is to worship as part of a religious community, but its latent function may be to help members learn to discern personal from institutional values. With common sense, manifest functions become easily apparent. Yet this is not necessarily the case for latent functions, which often demand a sociological approach to be revealed. A sociological approach in functionalism is the consideration of the relationship between the functions of smaller parts and the functions of the whole. Functionalism has received criticism for neglecting the negative functions of an event such as divorce. Critics also claim that the perspective justifies the status quo and complacency on the part of society’s members. Functionalism does not encourage people to take an active role in changing their social environment, even when such change may benefit them. Instead, functionalism sees active social change as undesirable because the various parts of society will compensate naturally for any problems that may arise. The conflict perspective The conflict perspective, which originated primarily out of Karl Marx’s writings on class struggles, presents society in a different light than do the functionalist and symbolic interactionist perspectives. While these latter perspectives focus on the positive aspects of society that contribute to its stability, the conflict perspectivefocuses on the negative, conflicted, and ever†changing nature of society. Unlike functionalists who defend the status quo, avoid social change, and believe people cooperate to effect social order, conflict theorists challenge the status quo, encourage social change (even when this means social revolution), and believe rich and powerful people force social order on the poor and the weak. Conflict theorists, for example, may interpret an â€Å"elite† board of regents raising tuition to pay for esoteric new programs that raise the prestige of a local college as self†serving rather than as beneficial for students. Whereas American sociologists in the 1940s and 1950s generally ignored the conflict perspective in favor of the functionalist, the tumultuous 1960s saw American sociologists gain considerable interest in conflict theory. They also expanded Marx’s idea that the key conflict in society was strictly economic. Today, conflict theorists find social conflict between any groups in which the potential for inequality exists: racial, gender, religious, political, economic, and so on. Conflict theorists note that unequal groups usually have conflicting values and agendas, causing them to compete against one another. This constant competition between groups forms the basis for the ever†changing nature of society. Critics of the conflict perspective point to its overly negative view of society. The theory ultimately attributes humanitarian efforts, altruism, democracy, civil rights, and other positive aspects of society to capitalistic designs to control the masses, not to inherent interests in preserving society and social order. Feminist theory is one of the major contemporary sociological theories, which analyzes the status of women and men in society with the purpose of using that knowledge to better women’s lives. Feminist theorists have also started to question the differences between women, including how race, class, ethnicity, and age intersect with gender. Feminist theory is most concerned with giving a voice to women and highlighting the various ways women have contributed to society. There are four main types of feminist theory that attempt to explain the societal differences between men and women: Gender Differences: The gender difference perspective examines how women’s location in, and experience of, social situations differ from men’s. For example, cultural feminists look to the different values associated with womanhood and femininity as a reason why men and women experience the social world differently. Other feminist theorists believe that the different roles assigned to women and men within institutions better explain gender difference, including the sexual division of labor in the household. Existential and phenomenological feminists focus on how women have been marginalized and defined as the â€Å"other† in patriarchal societies. Women are thus seen as objects and are denied the opportunity for self-realization. Gender Inequality: Gender-inequality theories recognize that women’s location in, and experience of, social situations are not only different but also unequal to men’s. Liberal feminists argue that women have the same capacity as men for moral reasoning and agency, but that patriarchy, particularly the sexist patterning of the division of labor, has historically denied women the opportunity to express and practice this reasoning. Women have been isolated to the private sphere of the household and, thus, left without a voice in the public sphere. Even after women enter the public sphere, they are still expected to manage the private sphere and take care of household duties and child rearing. Liberal feminists point out that marriage is a site of gender inequality and that women do not benefit from being married as men do. Indeed, married women have higher levels of stress than unmarried women and married men. According to liberal feminists, the sexual division of labor in both the public and private spheres needs to be altered in order for women to achieve equality. Gender Oppression: Theories of gender oppression go further than theories of gender difference and gender inequality by arguing that not only are women different from or unequal to men, but that they are actively oppressed, subordinated, and even abused by men. Power is the key variable in the two main theories of gender oppression: psychoanalytic feminism and radical feminism. Psychoanalytic feminists attempt to explain power relations between men and women by reformulating Freud’s theories of the subconscious and unconscious, human emotions, and childhood development. They feel that conscious calculation cannot fully explain the production and reproduction of patriarchy. Radical feminists argue that being a woman is a positive thing in and of itself, but that this is not acknowledged in patriarchal societies where women are oppressed. They identify physical violence as being at the base of patriarchy, but they think that patriarchy can be defeated if women recognize their own value and strength, establish a sisterhood of trust with other women, confront oppression critically, and form female separatist networks in the private and public spheres. Structural Oppression: Structural oppression theories posit that women’s oppression and inequality are a result of capitalism, patriarchy, and racism. Socialist feminists agree with Karl Marx and Freidrich Engels that the working class is exploited as a consequence of the capitalist mode of production, but they seek to extend this exploitation not just to class but also to gender. Intersectionality theorists seek to explain oppression and inequality across a variety of variables, including class, gender, race, ethnicity, and age. They make the important insight that not all women experience oppression in the same way. White women and black women, for example, face different forms of discrimination in the workplace. Thus, different groups of women come to view the world through a shared standpoint of â€Å"heterogeneous commonality.† Comparing the Four Sociological Theories Introduction to Sociology: 4 Basic Theories Conflict Functionalism Symbolic Interactionism Social Exchange Macro Macro Micro Micro -Inequality lies at the core of society which leads to conflict -Resources are limited -Power is not evenly distributed -Competition is inevitable (winners & losers) -Negotiations based on influence, threats, promises, and consensus -Threats and coercion -Any resource can be used as tool of power or exploitation -War is natural -Haves and have nots -Privileges are protected by haves -Order is challenged by have nots -Examples of: Gender & Feminist -Uses biological model (society is like a living organism) -Society has interrelated parts -What are functions or dysfunctions of parts -Society finds balance and is stable -Equilibrium -Society adjusts to maintain balance -How are parts integrated -Manifest functions -Latent functions and dysfunctions -Example of: Systems Theory -Society is an ongoing process of many social interactions -Interactions based on symbolic context in which they occur -Subjective perceptions are critical to how symbols are interpreted -Communications -Meanings -Significant others -Roles -Relative deprivation -Self -Reality shaping in self and with others -Key Ideas: Social construction of reality Thomas Theorem Definition of situation -Example of: theories of self -Society is an ongoing series of exchanges which occur during interactions -Interactions based on formula: (Rewards- Costs)=Outcomes Rewards -Costs -Profit/Loss -Comparisons -Limited resources -Power -Legitimacy -Equity -Negotiations -Tradeoffs -Example of: Levinger=s model on divorce: (Attractions +/- Barriers)=/-(Alternative Attractions)

“Night” by Elie Wiesel Essay

Elie Wiesel, a famed author and survivor of the Holocaust stated quite simply that anyone who witnessed a crime, and did nothing to stop it is just as guilty as the one committing it. Elie Wiesel learned a lot about man’s nature by surviving the Holocaust, but his statement about a bystander being just as guilty as the actual criminal is wrong. People are responsible for there own actions, and it is not fair to blame someone for a crime they did not commit, whether they could have done something to stop it or not. During the Holocaust there were over 6 million people persecuted, but there were many more silent bystanders who were unable to do anything because they feared for their lives. It is human nature to look after your own wellbeing and those closest to you, and many people felt if they tried to do something to stop the persecution of Jews it would endanger them in one way or another. In some cases somebody can witness a horrible atrocity, but have no power to stop it. Elie wrote in his book about how he and his fellow Jews were forced to watch the hanging of a young and innocent child by the S.S. The Jews that witnessed the hanging of the boy were all silent bystanders who, according to Elie, should be punished in the same manner that the executioner was. This shows how wrong Elie’s judgment is. The Jews were unable to do anything to help the boy for fear of their own lives, people cannot be blamed for their most fundamental and primitive instinct which is self preservation. Elie Wiesel experienced a lot of pain and suffering during the Holocaust, but the silent bystanders cannot be punished the same way the actual criminal is no matter what the circumstance is. If Elie truly believes that a silent bystander is just as guilty as a criminal, then that would mean that he is guilty of hanging a young innocent boy and deserves to be killed or sent to prison. Although it’s easy to see where Elie’s statement is coming from and why he chose to make it, it is clear that he made his statement more out of emotion than actual logic. I disagree with his judgment because silent bystanders do not always have the power to stop or intervene with the crime without endangering themselves.

Quest for Identity in Maxine Hong Kingstons...

Quest for Identity in Maxine Hong Kingstons Autobiography, The Woman Warrior Maxine Hong Kingstons autobiography, The Woman Warrior, features a young Chinese-American constantly searching for an unusual bird that would serve as her impeccable guide on her quest for individuality (49). Instead of the flawless guide she seeks, Kingston develops under the influence of other teachers who either seem more fallible or less realistic. Dependent upon their guidance, she grows under the influence of American and Chinese schools and the role models of Brave Orchid, Fa Mu Lan, and Moon Orchid. Her education by these counselors consequently causes her to abandon her search for an escort, the bird to be found somewhere in the measureless sky,†¦show more content†¦The first response, Yes, I have . . . Thank you. signifies the conventional Chinese response, valuing politeness, displaying modesty and consideration of the other, saving face (Ling 147). However, Kingston wants to give the assimilated American response, valuing honesty and directness, frankly looking o ut for number one, and tinged with humor, and Kingston thinks to herself No, I havent. . . . Im starved. Do you have any cookies? I like chocolate chip cookies (Ling 147). As evidence of Kingstons indecisiveness, Ling clarifies Kingstons cultural disorientation perceptible in her word choice: The expressed fondness for chocolate chip cookies seems a playful and somewhat greedy response, which Im sure Kingston intended. Can it then be that Kingston is advocating Chinese politeness at the same time that she is complaining about it? Is she subverting American directness while seeming to embrace it? (Ling 147). At this point in her autobiography, Kingston remains disoriented about her position in the two enveloping cultures, and Ling suggests this idea by considering the significance of Kingstons two culturally different responses rather than only one- either American or Chinese. Another result of American integration and participation in American

Juvenile Prisons And The Depression - 941 Words

There is a direct relationship between juveniles that are convicted and held in adult prisons and the depression it inflicts, creating a poisonous cycle of crime that they will be unable to escape from. After an increase of murders committed by juveniles during the early 1980s and throughout the 1990s, a quick adjustment was made by the supreme court and state courts to increase the abilities of the law to condemn violent juveniles with bleak futures into adult prisons to protect the children who had more optimistic chances. While the protection of the less violent children is important, however, there has been a great many studies that prove it is not the wisest way of seeing the situation at large. Juveniles in prisons designed for their age groups create a sense of value to them as human beings, are generally safer, and are more focused on rehabilitation into society as young adults. Sentencing a juvenile to an adult prison leads to feelings of worthlessness, depression, alienatio n and a fearful environment where they are unsafe and more likely to be encouraged to further their crime abilities to survive in an adult world. It is important to understand what the understood goals of punishment are. There are four goals of punishment. They are retribution, deterrence, incapacitation, and rehabilitation. The first goal, retribution, deals with punishment as a proportionate response to crime.

Review of the Movie Rob Marshall´s Chicago Essay - 653 Words

Chicago Review Rob Marshall’s Chicago is an adaptation of Maurine Watkins 1926 musical of the same name. The story took place in the roaring 20’s based on the concept of femme fatale and commercialized criminals. The plot of the movie revolves around ambition and the fickle nature of fame, and breaks the boundaries of stereotypical musicals in its unique theatricality and stagecraft. The success in the cinematic, theatrical, and editing elements aid in the creation of wonderful movie that is Chicago. To analyze a film requires the understanding of the setting, characters, and plot. The setting of the movie is in Chicago, hence the name of the film, during the 1920’s era where flappers and burlesque were becoming increasingly popular.†¦show more content†¦The film consisted of various streams of changing shots. As the set was in Chicago, the costumes designed took that setting into account to create realistic clothing for the characters portraying people of the 1920’s. The utilization of the many costumes of the actors allowed them to transform their characters during shooting. The characters in the movie stood out because a reflection of their attitude and emotion was shown in their costume and makeup. The lighting and sound of this movie also accentuated the acting, as well. With the loud, attention-grabbing music during Velma Kelly’s performances to the soft, innocent performances of Ms. Roxie Hart. During Velma’s performances, there was a lot of dramatic lighting giving the allusion of a spotlight at all times, however, during Roxie’s performances, there was a less dramatic tone to them. The elements of theatrics used in this film illustrated the story’s burlesque style performances to its highest potential. The editing of Chicago uniquely set this film apart from other films of the musical genre. The characters never stopped their actions to break into song as many other musicals do, the music al numbers used in Chicago are generally the daydreams or the backstory for a specific character.

Electron Microscope Essay Example For Students

Electron Microscope Essay The electron microscope, instrument that produced the first magnified image showing three-dimensional and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder, which contains the lenses, the specimen chamber, and the image-recording system. Two types of electron lenses are used, electrostatic and electromagnetic. They create electric and electromagnetic fields to both concentrate and move the beam. The electron microscope requires that the electron beam be in a vacuum, because electrons cannot travel far in air at atmospheric pressure. Pumps empty the column and specimen chamber of the electron microscope. Living specimens cannot be examined with an electron microscope, since they will not survive in a vacuum. The magnification in magnetic electron microscopes is determined by the strength of the current passing through the electric and electromagnetic lens coils. Changing the current through the objective lens coil focuses the image. In the optical microscope the image is determined by absorption of light by the specimen; in the electron microscope the image results from a scattering of electrons by atoms of the specimen. Since an atom, with a high atomic number, have more electrons than a light atom, it appears darker. As the beam passes through a specimen, each tiny differences in the structure of the specimen causes a variation in the electron stream. The image produced is then projected onto a fluorescent screen or recorded on film. The electron microscope, with its tremendous resolving power, can magnify specimens over 50,000 times.

Pakistan Essays - Provinces Of Pakistan, Poverty In Pakistan

Pakistan My topic deals with Pakistan, its relationship with the IMF and World Bank, and its internal problems that are causing unemployment, poverty, economic crisis and hunger. I shall be analyzing the situation using the neo-classical theory, as it is what the economists of the Pakistan government and the IMF are using to alleviate the economic instability of the country. Situated in the sub-continent, Pakistan is a low-income country, with great promise for growth. Unfortunately, it is held back from reaching middle-income status by chronic problems like a rapidly growing population, sizable government deficits, a heavy dependence on foreign aid, recurrent governmental instability and large military expenditures. It is to address these fundamental faults in Pakistan's economy that the IMF has initiated the Structural Adjustment Programs (SAPs) in the country. This is discussed in further detail later in the paper. Like all developing countries, Pakistan's population is largely employed in the agricultural sector, which accounts for about 48 percent of the labor force. In today's world the Industrial and Service sectors are the largest growing areas of a developed county's economy. Yet Pakistan only employs 39 percent of its population in Service, and a minute 13 percent in Industry. This is a paltry figure, compared to the employment statistics of a developed country. Pakistan is also heavily dependent on a single export crop, cotton. Hence the country's fortunes rise and fall with the cotton market. It is no wonder that there are so many poverty stricken people in Pakistan. When almost half the population is involved in a very volatile market, a lot of the time, a lot of people will be burnt by price fluctuations. The country is also subject to the mercy of the weather. Focussing on a major cash crop means very little diversification. This translates to mass hunger and hard times for the agricultural sector whenever the agrarian lands are ravaged by floods, or conversely, by droughts. Even more importantly, Pakistan's agricultural sector is marked by large landowners, controlling most of the production. Hence, only a minimal amount of the profit from exports goes to the poor people working for the large farmers. It is these people who constitute a large portion of Pakistan's population. It is also these people who are living in abject poverty in the rural regions of the country, devoid of the right to feed their families. This is a great illustration of a theme discussed in "World Hunger, Twelve Myths.' Lappe, Collins, Rosset and Esparza discuss the commonly believed myths about why hunger and poverty exist. In it they clarify this very important point: hunger does not exist due to a shortage of available food, but because of ?fear' and ?powerlessness,' resulting in the ?anguish, grief and humiliation' felt by the hungry and poverty stricken. Pakistan is a classic example of this theory. Based on a feudal system, especially in agriculture, Pakistani society is primarily controlled by feudal overlords, (a.k.a. the politicians or relatives of politicians), who own or oversee most of the agrarian land and industrial base. Being above the law, due to their political influence, these corrupt people can literally get away with murder. Thus, keeping their laborers subdued and underpaid is no hard task. Anyone who dares to complain is used as an ?example' for potential future unrest. As a result, the people in their ?elakhas', (controlled lands), remain destitute in the throes of poverty, unable to help themselves due to their lack of power and the fear of the ?thekedars', (large landowners). By a lack of power, I refer not to a dearth of physical prowess but to a scarcity of basic human rights. These are the same rights that people in developed countries take for granted. The right to vote for whomever one feels like is missing. Instead a lot of villagers are forced to vote for the local land owner due to a combination of fear and ignorance; a fear of the repercussions of a potential loss by the feudal lord and the ignorance of any means to escape this same overlord's wrath. Very often there is also no choice of candidates. There are very few people willing to risk their own and their families' safety by running against their subjugators. All this goes against the very nature of the free market economy that Pakistan is supposed to be running. While the IMF and World Bank are using Neo Classical theory to address the nation's problems in the capital, half the country is still being run under the feudal system. Till this system is broken, and
