A Look Inside a Woman’s World Essay -- Analysis, Kilbourne, Morgan

Humans are undeniably trained and wired to judge others based on race, gender, and appearance. Unfortunately, women are stuck in all categories of judgments. Jean Kilbourne, an award-winning producer on documentaries about images of women in ads, explains that when media and advertisements exploit femininity for personal gain, women are at risk for much harm because it promotes objectification, which eventually will led to violence. An African American feminist, Joan Morgan, expresses her further disturbance about the constant sexism in rap lyrics that endorses violence and anger towards women. â€Å"’Two Ways a Woman Can Get Hurt’: Advertising and Violence,† by Jean Kilbourne and â€Å"From Fly-Girls to Bitches and Hos,† by Joan Morgan reveals compelling arguments about the ways society often portrays females as an inferior gender to males. Our society today still fearfully unable to view pass the femininity of a women causing females to endures the suffering from forceful gender roles to excessive expectations by the infliction of our society, families, and media. Females are continuously objectifies by media in advertisement to be used as a tool for inappropriate sexual fantasy, which lead to violence towards women. Advertisements frequently utilize sex to show acts of power and hostility toward females of all ages (594). For the infamous Super Bowl Sunday commercials, companies like Pepsi Max and Snickers devalue females in their ads to appeal to consumers. For Pepsi Max commercial, the scene took place at a nice restaurant where a man and a beautiful woman is having a romantic date, while the woman in the commercial was wondering if her date was the one for her, all he could think about was his desire to sleep with her until ... ...n? Our society does not seem to notice their offense towards women, which will still continues due to the carelessness people tend brush off their shoulder when facing the effects of cruel expectations for women. From gender roles and expectations, females have suffers tremendously throughout all ages. There are numerous hardships and disadvantages females have to deal with in everyday life. Vicious judgments, discrimination, and objectification towards women demonstrate that our society has created a difficult world for women to live in. It is time for changes, a brake for all women to live life freely without worrying and suffering. The public views must acknowledge the struggles female endured and take the opportunity to look inside a woman’s world in order to prevent the torturing of all women from media, advertisements, families, and society’s judgments.

History of Statistics Essay

The history of statistics can be said to start around 1749 although, over time, there have been changes to the interpretation of the word statistics. By the 18th century, the term â€Å"statistics† designated the systematic collection ofdemographic and economic data by states. In the early 19th century, the meaning of â€Å"statistics† broadened to include the discipline concerned with the collection, summary, and analysis of data. Today statistics is widely employed in government, business, and all the sciences. Electronic computers have expedited statistical computation, and have allowed statisticians to develop â€Å"computer-intensive† methods. The Word statistics have been derived from Latin word â€Å"Status† or the Italian word â€Å"Statista†, meaning of these words is â€Å"Political State† or a Government. Shakespeare used a word Statist is his drama Hamlet (1602). In the past, the statistics was used by rulers. The application of statistics was very limited but rulers and kings needed information about lands, agriculture, commerce, population of their states to assess their military potential, their wealth, taxation and other aspects of government. Gottfried Achenwall used the word statistik at a German University in 1749 which means that political science of different countries. In 1771 W. Hooper (Englishman) used the word statistics in his translation of Elements of Universal Erudition written by Baron B.F Bieford, in his book statistics has been defined as the science that teaches us what is the political arrangement of all the modern states of the known world. There is a big gap between the old statistics and the modern statistics, but old statistics also used as a part of the present statistics. During the 18th century the English writer have used the word statistics in their works, so statistics has developed gradually during last few centuries. A lot of work has been done in the end of the nineteenth century. At the beginning of the 20th century, William S Gosset was developed the methods for decision making based on small set of data. During the 20th century several statistician are active in developing new methods, theories and application of statistics. Now these days the availability of electronics computers is certainly a major factor in the modern development of statistics. * Statistics helps in providing a better understanding and exact description of a phenomenon of nature. * Statistical helps in proper and efficient planning of a statistical inquiry in any field of study. * Statistical helps in collecting an appropriate quantitative data. * Statistics helps in presenting complex data in a suitable tabular, diagrammatic and graphic form for an easy and clear comprehension of the data. * Statistics helps in understanding the nature and pattern of variability of a phenomenon through quantitative obersevations. * Statistics helps in drawing valid inference, along with a measure of their reliability about the population parameters from the sample data. * Actuarial science is the discipline that applies mathematical and statistical methods to assess risk in the insurance and finance industries. * Biostatistics is a branch of biology that studies biological phenomena and observations by means of statistical analysis, and includes medical statistics. * Business analytics is a rapidly developing business process that applies statistical methods to data sets (often very large) to develop new insights and understanding of business performance & opportunities * Chemometrics is the science of relating measurements made on a chemical system or process to the state of the system via application of mathematical or statistical methods. * Demography is the statistical study of all populations.

An Introduction and Guide to Real Business Cycle Theory

Real  business cycle  theory (RBC theory) is a class of macroeconomic models and theories that were first explored by American economist John Muth in 1961. The theory has since been more closely associated with another American economist, Robert Lucas, Jr., who has been characterized as â€Å"the most influential macroeconomist in the last quarter of the twentieth century.†Ã‚  Ã‚   Intro to Economic Business Cycles Before understanding real business cycle theory, one must understand the basic concept of business cycles. A business cycle is the periodic up and down movements in the economy, which are measured by fluctuations in real GDP and other macroeconomic variables. There are sequential phases of a business cycle that demonstrate rapid growth (known as expansions or booms) followed by periods of stagnation or decline (known as contractions or declines). Expansion (or Recovery when following a trough): categorized by an increase in economic activityPeak: The upper turning point of the business cycle when expansion turns to contractionContraction: categorized by a decrease in economic activityTrough: The lower turning point of the business cycle when contraction leads to recovery and/or expansion Real business cycle theory makes strong assumptions about the drivers of these business cycle phases. Primary Assumption of Real Business Cycle Theory The primary concept behind real business cycle theory is that one must study business cycles with the fundamental assumption that they are driven entirely by technology shocks rather than by monetary shocks or changes in expectations. That is to say that RBC theory largely accounts for business cycle fluctuations with real (rather than nominal) shocks, which are defined as unexpected or unpredictable events that affect the economy. Technology shocks, in particular, are considered a result of some unanticipated technological development that impacts productivity. Shocks in government purchases are another kind of shock that can appear in a pure real business cycle (RBC Theory) model. Real Business Cycle Theory and Shocks In addition to attributing all business cycle phases to technological shocks, real business cycle theory considers business cycle fluctuations an efficient response to those exogenous changes or developments in the real economic environment. Therefore, business cycles are â€Å"real† according to RBC theory in that they do not represent the failure of markets to clear or show an equal supply to demand ratio, but instead, reflect the most efficient economic operation given the structure of that economy. As a result, RBC theory rejects Keynesian economics, or the view that in the short run economic output is primarily influenced by aggregate demand, and monetarism, the school of thought that emphasizes the role of government in controlling the amount of money in circulation. Despite their rejection of RBC theory, both of these schools of economic thought currently represent the foundation of mainstream macroeconomic policy.
