Teaching Evaluation - Essay Example Those who rely on auditory learning can listen to the lecture and the CDROM. The demonstration part of course helpful to learners who want to touch or experience the procedure. The best part of this method is teaching the student’s the process of preparing the lesson which is the best form of experiential learning. It also develops the habit of planning since materials needed should be anticipated to prevent waste of time. 3. None. No extraneous variables affected the teaching or learning in the group. The probability of having extraneous variables was eliminated by the fact the eight students belong to a group with very similar attributes like same year level. Also, there were no changes in the provision of instruction since the CD ROM is a constant. If there were many instructors delivering different topics, then the scenario would be filled with dependent variables. Thus, the group being homogenous plus the fact that the lesson is just one topic supports the justification that extraneous variables have no effect at all to the group. 4. No. First, the method being widely accepted as mentioned before confirms that this type of lesson is very feasible. From the setting of objectives which is focused on psychomotor skills, it is apparent that the lesson is being done properly because the desired learning outcomes match the objectives. The method is really relevant to the subject since the students must be able to demonstrate the skills in actual life. The materials support the methodology since lecture provides the facts and demonstration provides the enabling of skills through observational learning. Even in social learning theories, students learn by direct observation of an act; thus, this type of learning is recommended to students taking up nursing since the real job requires very high interaction with patients. Lastly, evaluation will definitely yield a good assessment due to the integrated teaching approach that covers all

Wine Making Essay Example for Free

Wine Making Essay Wine-making is essentially a chemical process. It involves a chemical reaction in which sugars are turned to alcohol and carbon dioxide in the presence of yeast. There are also many other chemical processes going on which affect the strength, appearance, colour and taste of the wine. Grape Ingredients Wine is made from grapes. In addition to water, grapes contain two different sugars: glucose and fructose, tartaric acid, malic acid, amino acids and a few other chemicals. The chemical processes of wine-making involve several of these components and the amount of each is important in determining the character of the wine produced. Glucose to Ethanol The most important chemical reaction in the wine making process is the breaking down of glucose by yeast, forming ethanol and carbon dioxide as gas. There are various important factors at this stage which affect the wine. First, sulphur dioxide gas is passed through the crushed grapes to kill off wild yeasts. If this was not done the yeasts would compete with one another and fermentation would stop prematurely. Controlling pH Next the pH (acidity) of the grape pulp needs to be controlled. If grapes are too sweet, then their pH is too high (acidity too low) then less flavours are produced in the wine. The pH can be lowered by adding tartaric acid at the start of the fermentation process. Temperature Finally the temperature must be controlled throughout the process. Fermentation is an exothermic process (heat is produced by the reaction), but there are various reasons for keeping the temperature as low as possible. Yeast stops growing as temperatures increase and will die at higher temperatures. Also at lower temperatures colours and flavours are extracted from the skins and by-products such as esters and aromatic compounds are produced which add to the flavour and also the clarity of the wine. Advances in Wine Chemistry As more and more research is done into the constituents of the wine and the way they are formed, two areas in particular stand out. First is the idea that regular consumption of wine in moderation is good for you. Statistical studies have shown that wine drinkers are less prone to heart disease, cancer and other diseases. This may be explained by the fact that wine drinkers tend to have a healthier lifestyle and are in groups which are less at risk to these diseases. It may be that there are certain chemicals that combat certain conditions, for example the antioxidant resveratrol which may reduce cholesterol and the risk of Alzheimer’s disease. These chemicals can, of course, be found in other food and drink without the damaging presence of alcohol. Improving Wine Making Then there is the development of the scientific study of the process of wine making, and the technology to improve it. There are many who would desire to depend on the natural processes of grapes and fermentation. Others have studied the chemicals which make up wine, seeking to determine those that cause the flavour, aroma and appearance of wine so that these can be manipulated in the production process. This tension will continue as the desire to make money affects the love of natural processes.

Automobile Trade Restrictions Economics Essay

Automobile Trade Restrictions Economics Essay The automobile industry is considered a very complex and vital industry compared to others, this is because of the development process with each project. The U.S. has said to have the most open automotive market in the world. The automotive industry has been a part of every major U.S. trade development dating back since World War One and is composed of three broad industries. These three industries consist of high-volume, full-ranged producers, which offer higher volumes and lower prices; while appealing to a mass amount of consumers. GM, Nissan, and Fiat are the main companies in this full-range producer and compete on a cost reduction basis. The second industry is the specialist producers, (BMW, Volvo, and Mercedes) these producers supply higher performance cars at higher prices and compete on the basis of differentiation and cost recovery. Lastly, there are niche producers, (alpine, TRV, and Ferrari), who offer on exclusivity and extreme performance. In addition to these producers, some trends can be identified when examining the global automotive market. These trends consist of the global Market, Establishment of Global Alliances, and Industry Consolidation. First, the global market is considered to be the worlds largest automobile manufacturer. The global market invests in production facilities that reduce production costs and are located in places such as Latin America, China, Malaysia and markets in Southeast Asia. Secondly, Establishment of Global Alliances are referred to as the, The Big Three (GM, Ford and Chrysler) who have merged in partnerships with other European and Japanese automobile manufacturers. Finally, Industry Consolidation involves increasing global competition among manufacturers and positioning within foreign markets. The U.S. is in the worlds top three automobile industries along with Japan and Germany. These automobile industries are major wealth generators for Europe and the U.S. recently providing over 17 million foreign and domestic cars and trucks in the U.S., which in turn accounted for more than 400 billion in sales. In addition to these producers and trends, there are six leading automobile manufactures, which are located in the U.S. and Japan. The U.S. consists of Daimler-Chrysler which is regulated by the United Nations, while General motors, and Ford are the other two in the U.S. The other three are produced by Japan and consist of Toyota, Nissan, and Honda. Between these six companies, they control over 87% of the market. The automotive industry has been a crucial part of the global market with automotive products accounting for ten percent of global merchandise trade. Fortunately and unfortunately with trade also comes trade restrictions. So what is a trade restriction? A trade restriction is defined as an artificial restriction on the trade of goods between two countries. The most known and important form of trade restriction is a tariff, import quotas, voluntary export restraints, and antidumping actions are also restrictions which will be explained in more detail later. In this paper I will explain trade restrictions/barriers that the U.S. imposes on the automobile industry, what programs are available to help make automobile trading more efficient and attractive for everyone, and also mention the various tariffs and trade barriers. In addition, I will talk about the current global automotive market , new foreign policy introduced in the U.S. and other nations, and finally explain the ramifications of certain restrictions and there effects on different people groups within the nation. First, there are many programs whose intentions are to help the automotive industry in trading. First are (APEC), Asia Pacific Economic Cooperation and Automotive Dialogue (AD) which serve as a forum for APEC. (APEC) attempts to find strategies to increase the integration and development of the automotive industry in a region. AD try to promote growth and development of the regional auto industry while also attempting to offer certain recommendations. Some of the economies that have participated in APEC and the AD include Australia, Canada, China, Indonesia, Japan, Korea, Malaysia, Mexico, the Philippines, Chinese Taipei, Thailand, Viet Nam and the United States. Many of these same countries have also tried and introduce new policies to make their country better off. For example, in 2004 China issued a new automobile industrial policy which discouraged the importation of automotive parts but encouraged the use of domestic technology in new vehicles assembled in China. In 2005, China issued regulations implementing the new automobile industrial policy.   The policy was said to unfairly discriminate against imported automotive parts and discourage automobile manufacturers in China from using imported automotive parts in the assembly of vehicles. In March 2008, Chinas policy was ruled inconsistent with several WTO provisions then in January of 2009, China complied with the recommendations and set rulings. Along with China, Korea also has attempted to bring out barriers that restrict importation and sale which include anti-import basis, standards and certification process and procedures, tariff and tax structure, and currency manipulation. So what are barriers/ restriction design to do? Barriers to entry are designed to keep out potential entrants from entering a profitable market. The barriers to enter the automotive industry are considered substantial, a new company must have the startup capital required to establish manufacturing capacity to achieve minimum efficient scale which is prohibitive. Many automotive established companies are entering new markets through strategic partnerships or through buying out or merging with other companies. Previously , the barriers to entry for new markets were low; However once the U.S. invited Japanese makers who began to offer quality vehicles in lower price markets compared to the U.S. changed this. Not only has Japan had success, many large automotive companies have globalized and entered foreign markets with varying degrees of success including, Asia, Africa, and South America whose barriers to entry are similar. As mentioned briefly before, there are a number of types of tariffs and trade Barriers that the government can employ and they include Specific tariffs, Ad valorem tariffs, Licenses, Import quotas, Voluntary export restraints, and Local content requirements. Specific Tariffs are considered a fixed fee levied on one unit of an imported good. Ad Valorem Tariff is based on a percentage of that goods value. Non-tariff barriers to trade include Embargoes, Subsidies, standards, and licenses which are granted to a business by the government which then allows the business to import a certain type of good into the country. So what effects can these barriers cause? Barriers can cause restriction in competition or increase prices on consumers. An import quota is a restriction placed on the amount of a particular good that can be imported. Voluntary Export Restraints (VER) is a type of trade barrier that is voluntary and is created by the exporting country rather than the importing one. Also, instead of placing a quota on a number of goods that can be imported, the government can require a percentage of a good be made domestically. The restriction can be a percentage of the good itself, or a percentage of the value of the good. Now that you know a little about tariffs and certain barriers, lets examine further the effect of tariffs and trade barriers on businesses and consumers. Patents, limit pricing, and cost advantages are all considered barriers to entry. In the short run, effects such as higher prices for goods can decrease consumption by individual consumers and by businesses, causing business profit and the government to see an increase in revenue from things like duties. However, in the long term, businesses can see decline in profits and efficiency due to lack of competition and future substitutes to their products. When speaking about the government, the long-term effect of subsidies is an increase in the demand for public services, overall resulting in less disposable income. When looking into the future, Japan continues its economic expansion which has allowed them to see continued success in exports. With the automobile industry being extremely competitive, the U.S. has worked with the, Big Three to introduce a program called the, PNGV which is a partnership for new generation vehicles. They aim to strengthen the U.S. global competiveness, keep jobs, while also trying to reduce the dependence of foreign oil, and improve the environment. The U.S. and Europe had increased concern regarding mobility, economic development, safety and environmental concerns when putting out new automobiles. As the government continues to try and provide incentives to reduce tax increases and fuel price increase they are also intending to find cars that reduce air pollution. Older models make automobile traded restrictions more difficult because of controversies over car prices and consumer preferences. Many consumers are now looking for vehicles that are equipped with, air-bags, power steering, antilock brakes, comfort, technology, and automobiles that reduce carbon going into the atmosphere. Car manufacturing must met safety, environmental, and business standard demand for international and domestic regulations. According to the future growth in the automotive industry over the next decade is expected to come from places like India, China, and Eastern Europe. Major companies are beginning to develop low cost cars, which include, Hyundai, Toyota, Fiat and others. With the increase worries about environmental issues, Hybrid sales have increased drastically. The U.S. and Europe are the main introducers of less pollutant and fuel efficiency standards in vehicles. So what are the ramifications of these barriers? Restrictions or trade barriers seem only to limit world trade, while also decreasing economic efficiency, reducing total production and employment, raise prices, and even cause retaliation. Some domestic companies benefit at the expense of foreign companies and workers, and domestic consumers. While subsidies do benefit domestic companies and workers in exporting industries, tariffs decrease exports and shift resources and production from more effective to less effective producers. In conclusion, while Japan continues to force competition on the U.S. It causes damage to the U.S car industry because of priced car exports. Causing the U.S. to now only represent s less than  ¼ of the world Industry and its market share continues to decline. Since 2007 the big three has been falling drastically. Chrysler is now selling 53 percent fewer vehicles since 2007, while GM is down 23% from 2007 and Ford 32%. Honda also saw declines along with Toyota who was down 37 percent, Nissan 31% and Honda 35 percent. All of these drops have caused oversupply in car lots, motivated dealers, easier financing terms, and long-term industry presence driving down the price of gas, making now the perfect time to purchase automobiles.

Americas Abortion Debate Essay -- Abortion

Abortion is one of the most controversial issues in the United States today. According to oxford dictionary, abortion is the deliberate termination of a human pregnancy, most often performed during the first 28 weeks. The two factions involved in this controversy are poles apart in their views on abortion: where as the pro-choice movement contends that a woman’s right to abortion is absolute, the pro-life movement asserts that a fetus’s right to life is indisputable. The argument has become very pronounced since the U.S Supreme Court ruling in the year 1973 in Roe V. Wade, which legalized abortion. According to the ruling, a woman’s right to abortion outweighed the rights of a nonviable fetus and prohibited the State interference. In addition to the fact that pro-choicers have always praised Roe for recognizing that a woman’s right to control her body is more important than a fetus’s right to life, this idea is also supported by different organizat ions such as Alan Guttmatcher Institute (AGI) whose mission is â€Å"to protect the reproductive choices of all women and men in the United States and throughout the world.† (Par 1) While some people believe that abortion is immoral others argue that it is a woman’s right to have full control of her body. A typical pro-life believer argues that fetuses posses a characteristic such as a genetic code that is both necessary and sufficient for being human. This idea is mostly propagated by the principle of the Roman Catholic Church â€Å"In 1995 Pope John Paul II officially condemned abortion in his â€Å"Evangelium Vitae,† calling it a villainous crime that kills an innocent human being† (Knapp Pg 16) and supported by many fundamentalist protestants groups, though not by majority of Catholics an... ...ciples, the pro-choice position is certainly not obviously wrong. Consequently, when abortion advocates try to make the argument more or less probable, they call for pro-life citizens to completely cease from bringing the legitimate idea of freedom to life for the purpose of protecting the unborn from harm, these abortion-choice supporters are by so doing encouraging their fellow pro-choice citizens to silently and politely remain firm that the unborn are not fully fledged members of the human community therefore are not entitled to protection by the state. To the opponent of abortion, this request hardly seems tolerant or liberating. Works Cited Francis J. Beckwith Defending Life: A Moral and Legal Case Against Abortion Choice.

Emotiv System

Emotiv System Min Company Background When Tan Le and Nam Do sold their company and earned a large of money in 2003, they decided to take a new challenge about processing brain signals. Then, together with Allan Snyder, a physicist and Neil Weste, a chip designer, they founded Emotiv Systems Inc.. The company built a R&D lab to develop a workable system about brain signals process. Finally, the team had a breakthrough-successfully developed basic technology called EPOC, which can detect 30 mental states and process brain signals into software algorithms.Now, The company wants to launch this new kind technology into market. However, there are many issues need to be decided, such as: 1. To launch as a PC-only device or both console enabled and PC enabled, which is better? 2. If Emotiv plans to launch into console market, what marketing strategy would best promote rapid adoption? 3. What kind of demand could materialize for the EPOC console-enabled? How about if only PC enabled? Technolo gy development about brain activity Actually, many approaches were developed all the time for transmitting brain activity.Tech| method| Advantage| Disadvantage| fMRI| Through magnetic properties of oxygenated blood | 1. Able to get strong signals2. Able to distinguish what different brain structures are doing| 1. Much cost2. Large size of apparatus| PET| Through injections of radioactive tracers| 1. More portable than fMRI machines| 1. Expensive process2. Consumer are hard to be willing to endure| EEG| Cross brain’s protective layers| 1. Portability2. Low cost| 1. Bad effects on signal quality| EPOC| Through a head set to capture brain signals| 1. Portability2.The cost is reasonable| | According the table above, we knew EPOC is a new technology that is innovative enough for Emotiv to seek launching into market. Console-Enabled market Gaming market is certainly a giant market from which the company can earn amounts of money and creates much profit, especially for console-enabl ed market. Then, it’s necessary to seek the chance to cooperate with console makers. The following is the comparison for seeking cooperation with different console makers. Console maker| Group of consumer| Issues| Nintendo Wii| Casual gamers| 1.Lacking in computational power. 2. Planing to focus on improving existing technology rather than trying a new one. | Sony PS3| Mix of hard-core games| Harm for cooperation:1. Sony company was highly divisive with PS3 hardware and software. 2. Sony Europe was willing to cooperate with Emotiv, but it needed to dumb down EPOC just for releasing a simple version. Benefit for cooperation:1. Sony PS3 is less competitive than Wii for less complex controllers and needs a new technology. 2. Sony Europe group has autonomy to decide whether to cooperate with Emotiv. Microsoft Xbox 360| Hard-core gamers| 1. Not include a high-definition DVD in console2. Taking a policy of â€Å"wait-and-see†. 3. Wanna others to prove the concepts first| Acc ording the comparison above, we can conclude Sony is the best choice if Emotiv manages to convince one of the console makers in time for a fall 2008 debut. And the demand of new product needs to focus on hard-core gamers. Then, the marketing strategy is the key to best facilitate rapid adoption. Product| With the platform of Sony PS3 and EPOC system|Price| Using Penetration pricing to capture market share| Place| Retail channel including Sony and Best Buy, e-tailers, company| Promotion| Bundling with PS3, Selling CDs with inclusion of experience, etc| PC-Gaming market For gaming, except console gaming, PC gaming also take over a large part. There’re several features as following. 1. PC gaming was less than 1/5 size of console market. 2. Game development for PC was less concentrated, then there were more PC games. 3. There had been a trend to open brain computer interface technology. . The demand of PC gaming would focus on very hard-core gamers and role-playing gamers. 5. PC and Console Gaming profits are inversely proportional to each other. Conclusion According all the information above, there’s a conclusion that EPOC will have a beautiful prospect with no matter Console market or PC-Gaming market. Emotiv may launch its technology at both the markets, but what it needs to do the most important now is firstly to launch at console market, seek to cooperate with Sony, capture the market and finally aim at other goals.

In footings of medical direction, osteoporosis is managed depending on different scenarios. It depends on the patient ‘s current medical consequences and on his / her medical history of vertebral breaks. It is besides different between male & A ; female patients with osteoporosis. The basic end of osteoporosis intervention is to diminish the frequence of bone break ; with hazard factors including low BMD, age, history of break, and hazard of falling. This can be done through medical process, consumption ( bisphosphonates, raloxifene, calcitonin ) , or therapy ( hormone replacing therapy ) . Diagnosis & A ; intervention of patients differs in five state of affairss: Post menopausal adult females holding multiple vertebral breaks ( governing other serious diseases out ) ; Post menopausal adult females holding osteoporosis and history of vertebral break ; Post menopausal adult females holding osteoporosis but without any diagnosing of vertebral break ( presently or in the yesteryear ) ; Aged individuals with hapless wellness and diagnosing of osteoporosis ( holding no history of osteoporotic break ) ; And, work forces with a diagnosing of osteoporosis with or without history of osteoporotic break. Treatment & A ; doses of medicative consumption are different depending on these five scenarios. It is with the ordering doctor and the person or patient ‘s consent that determines on how far they can continue in any pharmacological intervention in order to pull off osteoporosis and queer its patterned advance. To minimise hurting, both acute & amp ; chronic, use of the WHO Analgesic ladder has been suggested in order to mensurate the degree of analgetic consumption. In footings of new developmental interventions for the said disease, new happening engineerings has come up that non merely can offer curative maps in acute vertebral break but can besides diminish considerable hurting. These interventions are known as vertebroplasty ( shooting bone cement to fractured vertebra ) & A ; kyphoplasty ( infixing and blow uping a balloon to fractured vertebra typically before bone cement ) .

The difference chiefly in direction of these two sorts of bone tumours is that, since metastatic bone tumours have originated from a different sort or sorts of malignant neoplastic disease, intervention are with consideration to the patient ‘s original diagnosing of malignant neoplastic disease. Metastatic bone tumour in some manner has merely been an after consequence of the patient ‘s old unwellness. While in primary bone tumour where the original diagnosing has ever been foremost directed to the patient ‘s feeling of relieving hurting coming from the castanetss, the intervention is targeted straight on the said bone disease. Though, it has to be said that in handling primary and metastatic tumours, processs such as radiation therapy, surgery, kyphoplasty or vertebraplasty are all administered.

Last, patients who have undergone amputation are besides advised to take proper attention of their wellness and diet such as keeping good position, eating healthy & A ; imbibing tonss of H2O.

Free Essays on Khmer Rouge

Khmer Rouge is a name given to The Cambodian Communists. Khmer Rouge soldiers along with North Vietnamese and Viet Cong troops began their attack on government forces in the 1970’s and quickly gained control of over two thirds of the country. On April 17, 1975 a five-year civil war between the Khmer Rouge and the US-backed Khmer Republic of General Lon Nol ended. The Khmer Rouge established the state of Democratic Kampuchea and then set out to â€Å"purify† the â€Å"Khmer race†. The new government started by evacuating cities, abolishing banking, finance and currency, closing schools and factories, outlawing all religions, reorganizing traditional kinship systems into a communal order, and eliminating private property so completely that even personal hygiene supples were communal. Intellectuals and skilled workers were killed. As a result of the Cambodian genocide at least 1.7 million people (21% of the entire population) died. In 1979 Vietnamese troops invaded, aiding a rival Communist faction to remove the Khmer Rouge government from power. The Khmer Rouge, however, continued to continued to stay strong and held an army of 30,000 troops near the Thai border and retained UN recognition as the official Cambodian government. In 1991 All Cambodian factions signed a treaty for UN-supervised elections and the disarming of 70% of all their forces. The Khmer Rouge lost 3000 – 4000 soldiers, which is about half to three quarters of its forces in 1996. Since then it has continued to collapse. Factional fighting within the Khmer Rouge in 1997 led to their leader, Pol Pot's imprisonment by the Khmer Rouge. The group continued to disintegrate, and factional fighting resumed in 1998. Pol Pot died in April and by 1999 most members had defected, surrendered, or been captured....

Comparisson of Artist Using of the Human Figure Essay Example Comparisson of Artist Using of the Human Figure Essay Comparisson of Artist Using of the Human Figure Essay The three artworks created by the well-known artists; Michelangelo Buonarroti, Henri Matisse, and Cindy Sherman all convey different ideas and expression in their pieces. Each artist has used various materials and techniques to portray their figures in ways to represent their own emotions, ideas and values. The artworks David, Blue Nude (Icarus) and the Untitled Film Still, reveal the common use of the human figure to portray different artworks that carry strong and imperative messages to the viewers. Cindy Sherman is well-known for her artwork in observing human activity and weaknesses. She is an American photographer that incorporates herself wearing various disguises and prosthetic parts in her images. Different from her usually colourful and disturbing productions, Cindy Sherman created a series of black and white pictures starting in 1977 called Untitled Film Stills. David by Michelangelo took three years to complete, 1501-1504. This colossal 4. 34 metre tall sculpture illustrates the hero in the story from the Old Testament, David and Goliath. His extremely detailed artwork relates back to the idea of perfection and the religious ethics valued in this time. French artist, Henri Matisse uses colour and form to convey emotional expression in his artworks. He was the leader of the Fauvist movement where he changed the concept of colour in modern art and focused on reflecting images of peace and idealised places, ignoring the oppressing world around him. Creating a series of black and white film stills, Sherman uses Untitled Film Still No. 14 produced in 1979 to capture a portrait of a vulnerable, suburban housewife. In the image, Sherman stars as a stereotypical woman, using herself, props, furniture and sets to illustrate the low social class of women she portrayed in her series. Matisse, while using a distorted representation of a human figure, the Blue Nude made in 1952, captured his beliefs on the importance of intuition. He focused on the joy of art, expressing the form first and anatomy second using various intense colours and shapes. While Michelangelo on the other hand, portrayed his statue David as a muscular, divine man of youth representing the patriotic figure as a religious icon from the bible. He has based the piece on presenting the human form as detailed as possible and used marble to show the defined body creating an idealised figure. The artists have each used different techniques of expressing their figures. Sherman has used the media, film photos to lead the viewers into a drama of exaggerated stereotypes and cliches foregrounding the dominant discourse of gender equality. Typically for Matisse to use his bold colour in paint, in his bedridden days Matisse created a new medium called drawing with scissors which involved cutting shapes from pre-painted paper to create various shapes and images. Michelangelo used carrara marble to design his famous artwork doing intricate detail on the body to create an emotional intensity that fore grounded religious values during this period. Brought up in different eras, each artist has lived through some of the most significant political events and historical time periods the world has ever seen. Sherman, Matisse and Michelangelo all portray their views to their time in different ways using their love of the human figure to represent their own values and beliefs during these time periods. Cindy Sherman used her artworks to reveal her strong beliefs on marginalised voices of women. She had a strong political view on the dominant discourse of gender discrimination and portrayed her views through many of her photographic images. Conversely, Henri Matisse while living through many different and important conflicts of his time struggled to find a reason to incorporate his expressions of political opinion in his work. He focused on combining his ideas of joy and intuition with dramatic and intense colour to create a poetic energy from his art. Michelangelo Buonarroti had strong beliefs like the others but not of political interest he focused on portraying religious ideas into his art as religion was greatly valued in his society during this time. The ideas behind each figure are driven by different emotions, beliefs and values of the artist. The wine glass and coat seen in Sherman’s untitled film still 14 create the idea of empowerment from a man in the household. Her back seen in the mirror implies she is vulnerable and exposed to the dangers around her, possibly the leading man in the house. Her face is worried and fearful creating an unsettling eeriness along with the black and white of the image. These techniques have allowed Cindy Sherman to portray her ideas on the vulnerable woman defenceless against men. Matisse’s distorted figure is bold and captivating showing an immediate focus point in contrast with the background which is soft. The movement of the body figure is free and rhythmical with the red circle representing the heart, burning with fiery desire to be liberated. Not having an exact face but a blank canvas gives the impression that one and everyone desires to be free. The patriotic icon David is followed with such finer, complex detail with the figure representing superior power like that of Adam, the first human being from the bible. The beautifully portrayed hero is made in the image before David went to battle showing the strong concentration in his facial expression. Although from an unaware observer’s perspective of the statue, Michelangelo has in fact made the sculpture incredibly out of proportion. Having exceptionally long arms for his body, different length legs, and huge hands, Michelangelo has made it seem unnoticeable to the naked eye also concentrating on his much finer details takes away from the large faults. All Henri Matisse, Cindy Sherman and Michelangelo Buonarroti have used different techniques of expressing their figures and their messages. They each convey different ideas behind the image but all use the human figure to represent their values in different ways. Blue Nude, Untitled Film Still no. 4 and David by the well-known artists are portrayed using art to extend the artist’s messages across to the world. They have revolutionized the way modern art is perceived and will continue to inspire people to express their own opinions through art.

Behavioral Finance Heuristic and Judgment, a literature review Essay

Behavioral Finance Heuristic and Judgment, a literature review - Essay Example In subsequent studies, Fama (1998; with French 1992/1993/1996) and Malkiel (1995) showed empirical evidence proving these conclusions and the observation that in efficient markets, only those that arrive first can earn above average returns. This logic that consistently beating the market is impossible (returns are so low that most will go to trading fees and commissions) led to the creation of index funds that mimic market performance. On the other side are the behavioral finance academics who claim that capital markets are inefficient, citing observable market anomalies showing that stock price behavior is predictable, that investors are irrational, and that many can earn above average returns or beat the market (Shiller 1981/1990/2000). Barberis, Shleifer and Vishny (1998) claim that in the ongoing battle between rational and irrational traders in the market the irrational ones are dominating. The systematic errors that irrational investors make when they use public information to form expectations of future cash flows overwhelm the efforts of rational traders to undo the former's market dislocating effects. Daniel, Hirshleifer, and Subrahmanyam (1998) state that irrational traders' overconfidence in interpreting private information pushes up prices above rational fundamentals and increases market inefficiency. Behavioural finance studies are backed by empirical evidence showing market inefficiency caused by limits to arbitrage (Shleifer and Vishny 1997) and behavioral psychology, both individual (Shleifer 2000) and collective (Hirshleifer and Teoh 2003), as factors that explain inefficient market behaviour. One stock anomaly cited as proof of market inefficiency is the so-called January effect that can be stated simply as "stock prices tend to go up in January" (Gultekin and Gultekin 1983). Thaler (1987) and Shiller (1997) attributed this to psychological factors as investors are influenced by their own mental compartments. Fama (1998) claims that conclusions based on market anomalies discovered by behavioral finance are due to poorly done statistical work and amateurish techniques. He cited above average returns as the result of chance, that behavioral finance models are loaded with judgmental biases making it predictably easy to justify any hypothesis proposed, and that the efficient market hypothesis can explain all forms of market behaviour to date. Nevertheless, despite the voluminous literature on the topic, both efficient markets and behavioral finance proponents agree that their models have not managed to fully explain capital markets behavior. Sharpe, a 1990 Nobel Prize winner who supports both theories said that "as a practical matter it is prudent to assume the market is pretty close to efficient in terms of pricing and risk and return On the other hand, we have learned from cognitive psychology that ordinary human beings needalternatives

Why is it important to have a Masters Degree Essay

Why is it important to have a Masters Degree - Essay Example Bachelor Degree is basically the minimum qualification required for a profession whereas Masters Degree is essential for higher opportunities in career. This paper briefly analyses the importance of Masters Degree for one’s career development. In industry sector, Masters Degree is essential for the career development. For example, it is difficult for a person with a Bachelor of business administration degree to excel whereas a person with a Master of Business Administration may help him to achieve higher places in his organization. Some people use Master degree for a change of their profession. For example, a Bachelor in economics can opt for a Master in Business Administration if he/she decides to change their profession after the completion of their bachelor degree in economics. Master Degree provides the maturity in learning to the student. Most of the students up to their bachelor degree may not give much emphasize to their education. On the other hand, most of the Master Degree students avoid all other leisure activities and give more importance to their studies. In other words, most of the students become well matured during their Master Degree studies. For a teaching profession in universities and colleges, Masters Degree is essential since majority of the college or university students are studying either the Masters Degree courses, Graduate courses or undergraduate courses. It is impossible for a Bachelor Degree holder to teach a Master Degree student. Even for doctoral degree, it is better for a person to achieve Masters Degree first. In fact Masters Degree is the base for a Ph.D. In terms of course works, Masters Degree always provides the base of Ph.D. People often achieve Masters Degree during their early twenties during which they would be more matured compared to other stages of their student-hood. Masters Degree often gives the choice of specialization. Up to Master Degree level, students often study subjects on a

William James, The Will to Believe Essay Example | Topics and Well Written Essays - 1500 words

William James, The Will to Believe - Essay Example Only a genuine option is relevant. James creates a three-part test for determining whether an option is, in fact, genuine. This three-part test requires that an option be living, forced, and momentous in order to be genuine. As an initial matter, there must be two alternatives. To be genuine, the option must be living. This means that the individual in question will consider seriously each of the alternatives. It must be possible that he will choose either of the options. In this respect, the genuine option becomes extraordinarily individualistic. The test is not applied to groups, whether large or small, but to the smallest possible unit. The test is applied to the decision-maker. This has significant implications. An option may be living for one person but not for another. In a very basic way, the person must be thoughtful, open-minded, and undecided for the option to be living. Assuming that the option is living, the second part of the test requires that an option must be forced. The forced element demands that an alternative be chosen. There can be no hedging. There can be no qualifications of the choice. There is a sense of completeness and irrevocability demanded by this element of the genuine option. You have faith or you do not have faith. You like a person or you do not like a person. There is, in short, a conflict and it must be resolved. The final part of the test concerns the uniqueness of the option. James refers to this as the momentous option. In his view, this option presents itself as a once-in-a lifetime opportunity. To be momentous, the option must transcend trivial issues. The option must involve truly significant matters, the decision must be irrevocable, and the decision must be unique. This limits the discussion to very fundamental issues, such as deeply moral questions, religious questions, and personal relations. In the final analysis, James argues that the question of religious faith is a genuine option because the question satisfies the three-part test. When confronted with the question of religious faith, the option may very well be living to many individuals. The individual may consider both alternatives, to have faith or not to have faith, very seriously. Faith is forced in the sense that, after considering the question, a choice must be made. You do not have faith in salvation without a corresponding faith in hell. Finally, this question of religious faith is a momentous decision. The notion of God is hardly trivial. The notions of salvation and eternal damnation are quite significant. How an individual defines his existence, and leads his life, can be fundamentally affected by this decision. Is this type of religious faith then a rational faith James believes that religious faith, as qualified by the genuine option approach, is rational. Again, his framework relies heavily on the concept of circumstance and individuality. The need for absolute evidence is tangential. This rationale is justified by reference to what he calls our passional nature. Our passions motivate us to act. They are not objective. They are specific to each individual. We are all possessed of

Fossils and their interpretations essay Example | Topics and Well Written Essays - 1000 words

Fossils and their interpretations - Essay Example Several paleontologists have managed to collect close to 2000 Eusthenopteron specimens, which have been effective at providing room for the detailed study of this species. Basing on the anatomy, Eusthenopteron shares several unique features that are common with some earliest known tetrapods. The largest individual was capable of growing up to 1.8 meters in length, while is also shares the similar pattern of the skull roofing bones with other forms, such as Ichthyostaga and Acanthostega. Eusthenopteron like any other tetrapodomorph fisheries had internal nostrils, which are only found in the land animals. From this fossil, one can develop a thesis that all creatures developed from a transition of other creatures. The image of this fossil is as shown below; Figure: Eusthenopteron foordi. University Museum of Zoology Cambridge specimen GN. 786. Scale bar is 10 millimeters. Photograph by JAC Pathologists Jennifer A. Clack (2002) believes that Eusthenopteron showed some characteristics of crawling across the dry landscape with the help of its fore fins while moving around. This fossil also shows that it had labyrinthodont teeth, which are characterized by the infolded enamel, which also characterizes the rest of earliest known tetrapods as well. ... The appendicular long bones of this fossil shows that it had some epiphyseal growth plates that were essential at allowing substancial longitudinal growth through the endochondral ossification, as similar to the case of tetrapod long bones. The genus has six appendicular bones that also occur in tetrapods and are thus a synapomorphy of the large clade of sarcopterygians, which is also possibly the subclass Tetrapodomorpha. This genus also lacks some superficial odontodes on its elasmoid scales, which are composed of the dentine and enamel. The lack of such similarities implies that there is a synapornorphy with more crownward tetrapodomorphs. The genus Eusthenopteron also differs from the later Carboniferous tetrapods basing on the apparent absence of some recognized larval stage and the definitive metamorphosis. But on the even smallest known specimens of the Eusthenopteron foordi, when it attains a length of 29mm, the lepidotrichia is able to cover all the fins, which on the contra ry do not happen with after metamorphosis occurs in the genera like Polyodon. This has the implication of stating that Eusthenopteron developed directly, with its hatching already managing to attain the general body of the adult species. This therefore implies that Palaeospondylus gunni might not have been the larva of Eusthenopteron. The author responds to these claims about Eusthenopteron with some sort of analysis. There are emerging issues that now, nearly 20 years of which this subject has undergone a renaissance; there is much enriched fossil record to draw implications from. However, much of this recent work is yet to reflect on the popularity of the accounts on this subject. There is some assumption that Devonian tetrapods and the respective close fish relatives originate

Mate choice & plumage polymorphism in the feral pigeon (Columba livia) Essay

Mate choice & plumage polymorphism in the feral pigeon (Columba livia) - Essay Example Assortative mating is a process where two similar or dissimilar individuals mate where as Disassortative mating involves choosing of a partner for progeny benefits from the range of the parental genotypes. Aim of this paper is to evaluate the association of plumage polymorphism and mate choice in feral pigeons using Chi-square test. In particular, this paper analyzes the plumage colour preference as either dependent or independent in the mating process of the male and female feral pigeons. If the pigeons choose their partner in harmony with plumage colour then it is defined as dependent pairing and if they choose their partner without considering colour then it is independent pairing with respect to plumage colours. The purpose of the study is to understand feral pigeon’s plumage based mating increases the reproductive output and extend their lifespan which are also based on environmental conditions. The colour categories used for this study are melanic, blue-grey and other colours including pale/brown pigeons. â€Å"The other colours noted in feral pigeons are faded, pale, reduced, opal, indigo, milky, pearl eye and more.† (Miller 1997). The research on feral pigeons plumage based mating is carried as described in academic handbook using Chi-square test of independence. Chi-square test of independence tests the association between two definite variables. Colour of males’ plumage and colours of females’ plumage are the variables used in this test. The result (χ2) is then looked up on a Chi-square (χ2) table with a number of degrees of freedom (df). â€Å"We determine df for the Test of Independence by the formula df = (r-1)(c-1), where r = the number of rows and c = the number of columns.† (Yount 2006, p.6). â€Å"Chi-squared distribution table.† (The chi-squared distribution table, n.d.). ‘Expected Value’ Calculation: Using the ratios (relative frequencies) of three colour morphs in observed population, the expected values

Psychology Reflective Essay Example for Free

Psychology Reflective Essay After having various lessons, I would like to have a deeper evaluation of the chapter â€Å"Behavior in Social and Cultural Context† especially the concept of attributions . It is known that there are two types of attributions which are internal attributions and external attributions that we generally use to explain our own or other’s behaviors. Internal factors concern a person’s traits while external factors concern the external environment. In addition, I am actually shocked by the fact that there is a fundamental attribution error when we are explaining others’ behaviors. There is a real-life example that I would like to share. Last Monday, I was stuck in a traffic jam for half an hour on Nathan Road. I had a lesson at 8:30 am in Core A and I reached the pedestrian bridge at 8:25 am, so I was rushing to the classroom. At that moment, a scene annoyed me most and stopped my way to school. A boy who was around six years old was too energetic. He dashed and rushed around on the footbridge that disturbed others’ way. He also guffawed and touched or played with anything and everything he saw. Suddenly, he paced around and glared at his mum. Don’t walk like a stupid pig! Do you know how to walk? I have been waiting for you for so long! †He shouted at his mum. At that moment, I was very angry and strongly believed that the boy was so naughty and disrespectful that he showed his emotions with no restraint and did whatever he likes without regard for consequences. Based on the above case, the correspondence bias leads me to explain the boy’s behavior by ignoring the influence of situation on behavior. For example, actually he is a child with attention deficit hyperactivity disorder, so he cannot be patient and always dash around. However, we tend to emphasize the dispositional attribution that the boy is so naughty and disrespectful. Apparently, we tend to overestimate internal factors and underestimate external factors when explaining others’ behavior. After understanding the concept of fundamental attribution error, I have an enquiry related to it. Is there an error too when we explain our own behaviors? In order to find out the answer of it, I do some researches on it. Afterwards, I found out that the concept of actor-observer bias which is proposed by E. E. Jones and R. E. Nisbett in 1971 gives a clearer picture on the error of explaining our own and others’ behaviors. It states that we as an actor are more likely to attribute our own actions to the particular situation than to a generalization about our personality while the reverse asymmetry held for people being an observer and explaining others’ behaviors. Nevertheless, I have doubts about both the fundamental attribution error and the actor-observer bias. In my opinion, I think that both of the ideas only firmly established when describing negative events. For instance, on the one hand, as an actor, when we get bad result on an exam, we usually attribute the reason to the difficult exam (situational). On the other hand, as an observer, when our friends get bad academic result, we usually attribute the reason to his or her lazy character (dispositional). If the event is positive, the reverse error occurs. With the same example but with the condition that both we and our friends get high marks in the exam, we will attribute the reason to hard-working (dispositional) and easy exam (situational) to explain behaviors respectively. Malle (2006) agrees that a reverse asymmetry held for positive events after conducting a mental-analysis. He states that the discrepancy may indicate a self-serving pattern in attribution that we attribute success to internal factors and failure to external factors. Therefore, I believe that we are explaining others’ by using both the self-serving bias and fundamental attribution error. Overall, the lessons build up my foundation for the psychological concepts and theories and we need to explore the psychological world by ourselves in order to find out more details, conflicts about and relationships between different ideas. For instance, in order to finish this reflective journal, I used Google scholar to search about the actor-observer bias and the criticisms about it that I did not learn on the book and in lessons. By experiencing the searching process, I have deeper understanding on it and it strongly impresses on my memory. The process also enhances my analysis skill, to determine which sources are useful and which sources are not related to my topic. Therefore, I enjoy the process of exploring the psychological knowledge by ourselves.

Weapon Trafficking When Will It End Politics Essay

Weapon Trafficking When Will It End Politics Essay The news that people hear coming from Mexico, especially in recent times have not been very positive. The continuing violence along the U.S.-Mexico border has escalated even more dramatically within the past few years, mainly because of the Mexican governments constant efforts to cut off Mexican drug trafficking organizations (DTO). The violence associated with Mexican DTOs continues to hurl major challenges and obstacles towards U.S. law enforcement, while at the same time threatening the citizens on both sides of the border. Drug trafficking may be the root to these problems, but the firearms used to perpetrate crimes in Mexico are being illegally trafficked from the U.S. across the southwest Border and is causing serious problems as well. There needs to be a complete removal, or at the least a reduction of the illegal arms passing through the border, but this can only occur through an improved sense of security and supervision and regulation of the arms market. Not only will the f ailure to bring improvement to this situation raise the level of violence and deaths along the U.S.-Mexico border, but will further diminish what the border was made to stand for, in promoting free trade and globalization. To start off, Mexico itself has very strict gun laws, especially the gun-ownership regulations. Very rarely will you witness citizens carrying guns with them or around the house, because of the serious issues that revolve around the possession of these weapons. Since the countrys already existing constitution makes it legal for the citizens to bear arms, the conditions it places on the actual ownership, through amendments to the constitution prove to be much more strict and limiting. The fact that only one body is permitted to sell weapons, and it is run by the army makes it even harder to attain or own these weapons (Ellingwood). Although these rules and regulations are given to the citizens of this country, it does not mean that the weapon-smuggling situation is completely under control and taken care of; as you will learn later on, there are definitely a few ways around any law or institutional arrangement, and the involving parties definitely know how to make the most of the ways around the system by utilizing many types of illegal trade. Yet the violence in the northern border states of Mexico seems to be produced not only by weapons being brought illegally from Mexico, but also by those weapons trafficked illegally from the United States. Since these dangerous firearms are still not legally available for sale in Mexico, it leaves it up to the various drug cartels to smuggle them through the U.S. or Guatemalan borders, or even by sea as a last resort (Money, Guns). A good number of these firearms are brought in by foreign countries by cartel members that participate in these illegal trades and theft and then they are smuggled to Mexico a few at a time. Now in a neighboring country, such as our very own, where most people who own guns have the right to bear arms and are protected by the rights, a small number of gun shows are put together and showcased nearly every weekend of the year. States like Texas, Arizona and California are considered to be the three main source states and hotspots that supply for the vast majo rity of the guns that are bought and snuck into Mexico (Gunrunner). To be able to absolutely prevent these guns from making their way south is a pretty tough battle that challenges the power of the second amendment rights of US citizens against the ever so bloody battles and increasing numbers of Mexican victims of these mini wars that are killed everyday by these brutal weapons that are bought here in the US (Gun Control). As far as the locations where these guns are purchased from, the Gun shows that are put on by the source states take place a couple of times a year, as mentioned earlier. For example, in Arizona, the gun shows occur almost every weekend. They are often times organized by a variety of different groups and unified organizations. One of the well known organizations goes by the name of the Arizona Arms Association, and since they are a group that is most importantly legal and allowed, they are given the power to partake in private transactions between gun owners and citizens. In being able to utilize such a network of these strawmen, the native Mexican arms traffickers have the potential to collect over a dozen of different weapons each weekend (Cartel). After they gather these weapons each week, their next move is to smuggle them into Mexico, which is usually executed using over land routes with a wide range of vehicles and means of transportation that are able to hold a quantity of weapons that are much smaller across the various border crossings. This type of smuggling, in which smaller groupings of guns are smuggled across the border, is known to be called ant trafficking, and continues to serve as one of the biggest reasons why it is so hard to actually detect these weapons that are being pushed down south from the U.S. region of the border. Now focusing back on the gun show, in the positions of the vendor, some private vendors are often entered into the world of the gun trade by taking on the role of a supplier, where he/she takes the orders ahead of time and to make deliveries at a later time, which would most likely take place at an upcoming gun show or event (Gun Control). These people then round up the repeat clients and gradually produce the majority of the supply source for the arms traffickers which have been reported by Bureau of Alcohol, Tobacco, Firearms, and Explosives also known as the (PAYAN). Once again, as mentioned earlier the main issue with this is that these transactions are not always closely and precis ely monitored, and so more times than not it puts the salesperson in a position where he/she is able to recognize interested buyers who are likely to be purchasing weapons for a third party. These so-called strawmen who serve as salesmen are the main suppliers and catalysts of these illicit and dangerous weapons that flow southbound, which they sell off to or illegally hand to gun traffickers who then round up and separate into groups and categories of the shipments at certain border crossings. Once they reach their destination in Mexico, the weapons smugglers are ready to make thousands and thousands on their merchandise (Gun Control). For example, an already used AK-47 assault rifle may sell for around 400 U.S. dollars and possibly more. In addition, an AR-15 rifle also has the potential to sell for 800 U.S. dollars up to 2,000 U.S. dollars, but that depends mostly on the model number of years it has been in production for that specific weapon as well as other options and accessories such as the scope or trigger. In Mexico, these weapons start to become more valuable and rocket in re-sell price, and in some rare cases as much as a whopping triple or more, according to the ATF (Gun Control). So an AK-47 rifle that has been purchased in Arizona for about 500 U.S. dollars might go for as much as 1,500 U.S. dollars or more once it crosses the border (Gun Control). At border crossings, Mexican customs agents are usually in the perfect position to interrogate and have the right to detect all smuggled weapons, but their can be a gut-wrenching one at times. Many times, these agents are given a pretty harsh ultimatum which goes by the name of Plata o plomo, meaning silver or lead which then translates into take the bribe or take a bullet. This message, is often times sent by Mexican organized crime groups and targeted to those who patrol the Mexican side of border crossings, known as plazas (Cartel). So here is another factor in why it may be difficult at times to put a halt to the weapon trafficking. Since these Mexican cartels are so menacing and uncooperative, the custom agents who are given the task to detect weapons, are presented with life and death decisions. Certain happenings like these just add on to the fact that it will be difficult to put an end to this war. These kinds of encounters are vital in understanding the rise of violence along the borders, because agents should not be in a position to be fearing of their lives. In the US, the second amendment advocates and supports the gun shows that many people consider an excuse to make weapon smuggling allowed and operating. While the political views surrounding tracing and information sharing can be a bit complicated, the procedure of buying the guns and the required background checks has been reorganize and restructured. These background checks are not required at gun shows because the sales are oftentimes considered to be made between two private and unlicensed individuals instead of a licensed dealer and an individual, which usually takes place in legitimate gun stores where a background check is indeed mandatory. Even the background checks that are made in gun stores are simple and quick (Gunrunner). For example, when a customer at a store is ready to make his/her purchase, the seller of the product is supposed to make a phone call to an ATF hotline, where the person gives out the proper information to the person talking on the other end of the hotl ine. Usually, this process should take less than five or ten minutes, but within the past couple of years, this background check has transformed into a slow and grueling process (Gunrunner). As for the strawmen, who buy off the weapons from law abiding gun merchants serve as a stepping stone into the crooked world of the grey market, where the weapons stay put until they are smuggled into Mexico and then resold. Before these guns are let into the hands of others, usually for criminal use, expert gunsmiths thoroughly check and inspect the working parts, and clean them for the necessary adjustments to transform a usual semi-automatic into a dangerous fully automatic assault weapons. They tweak parts of the gun and make them stronger. Once the strawman flees the scene of the store with gun in their hand, or leaves the show area in the case of a gun show or event, it becomes pretty much impossible to trace the weapon until it is picked up or discovered at a crime scene or if it has been seized. Often times, the weapons that have been captured in Mexico are able to be traced back to gun stores in the US, but the only pieces of information the gun dealer is allowed to legally share with is the information that has already been attained and solidified by the background check. As you can see, the tracing of the weapons captured in Mexico back to the US is proves to be a very complicated and frustrating matter. Due to this complicated process, a large number of weapons usually remain untraced due to the fact that the agents do not want to harass or bother with the bureaucracy (Cartel). In the U.S., there are approximately 2 million guns owned currently, and at any given time, any one of these guns has the potential to be sold to both men and women who will then smuggle them to Mexico. Reasons can range from personal use and self-defense while others for recreational or criminal use. When put together, the mixture of such a enormous supply with demand mixed in with the ant-trafficking produces a countless number of opportunities and possibilities, variables and pretty much leaves the ATF and others with only a limited arsenal of legal tools and, most importantly, gives them the constitutional rights to respect and defend (Gunrunner). As you can see, the conflict here resides in the fact that there are so many possible ways for these weapons to be smuggled, and with all the underground activity that is going on, it can be a very difficult task for the ATF to track down these trades at times. In a sense, the amount of illegal trafficking that is being presented here c an also be overwhelming to the forces that are trying to prevent the illicit trafficking of these weapons. As far as the types of guns that are smuggled, the most popular, or common smuggled firearms include the AR-15 and AK-47 type rifles, FN 5.7 caliber semi-automatic pistols and a variety of .50 caliber rifles and machine guns (AK-47). About a fourth of these AK-47 assault rifles that have been seized have also been created and fixed up to select fire weapons, which then allows for the assault rifles to be used by the cartels (AK-47). In the past, there have been a great number of reports regarding grenade launchers being used against security forces, and at least a dozen M4 Carbines with M203 grenade launchers have been confiscated (AK-47). It was believed that a lot of these lethal and high power weapons alongside their related accessories were actually stolen from U.S. military bases. However, the majority of these military grade guns and heavy duty weapons like grenades and light weight rockets are brought in by the cartels via the humongous supply of arms that remained after the w ars in Central America and Asia. The weapons that are being smuggled are serious weapons that can cause heavy damage and harm, so just the fact that the weapons talked about in this arms trafficking war are heavy duty once again reminds us of how dangerous this situation can get. This constant flow of arms between groups has lead to what has been dubbed the iron river of guns, because of the pouring amount of ammunition and light weapons that have been in flow southbound into Mexico, and how the organized crime hit men and others then use them in order to fight off the Mexican military and police. More times than not, innocent civilians are caught in the midst of shoot outs and random collision between the opposite groups and that is what leads to the rising number of deaths and high volume of violence throughout the years. The resulting body count that is the end product of this violence has greatly pressured the Mexican government over time to call for additional help from the U.S. capital, but these leaders have continued to remain silent and stubborn to put forth a strict gun control legislation. Many have waited and waited for someone to step up to the plate and address the problems along the border, but the subject has been ignored time and time again. Finally, in April of last year, a statement was made by U.S. President Barack Obama regarding the ongoing arms trafficking situation between the U.S. and Mexico, and to no surprise it sparked a serious and very much heated debate. The President, who referred to the data gathered from the Bureau of Alcohol, Tobacco, Firearms and Explosives (A.T.F.), stated that 90% of the weapons that were seized in Mexico could be traced back to the U.S. (ATF) In concurrence with supporters of putting forth a stricter gun regulation and opponents of the so-called War on Drugs, this information helped their cause and pushed to strengthen their cases. On the other side of the table, the statistic of 90% was greatly criticized and put down by the people who were against the finding of new or alternative solutions to the current situation in Mexico and also to any thoughts or ideas of making some changes regarding gun ownership in the U.S. Out of all the top news corporations, Fox News projected that the percentage of arms that could be traced back to the U.S. was actually closer to 17% percent (Gunrunner). This is a prime example of how things can get taken out of context and a serious issue at hand can be mistaken or overlooked because of little details that are misrepresented or reported. Not only does this add more unnecessary nonsense to a situation and blow it up bigger than what it already is, but it makes the already existing problem a dragging subject. In order to give the material substance and to enhance its rich meaning, all data must be presented in its original context; otherwise, statistics risk becoming meaningless sound bites and generalizations. In the Firearms Trafficking Report, given by the American Government Accountability Office (GAO), they explain the importance that even though it is pretty much impossible to know the exact number of firearms that are illegally smuggled into Mexico in a certain year, roughly 87% of the firearms that are obtained by the Mexican authorities and traced within the past couple of years originally started off in the U.S., according to the data that was gathered from Dept. of Justices Bureau of Alcohol, Tobacco, Firearms and Explosives. Also, according to the Mexican and U.S. officials, these firearms have been increasingly more powerful and lethal in recent years. The report continues to polish and purify its data and information, by pointing out that between 2005 and 2008, more than 90% of the firearms that were obtained in Mexico and traced have once again, come from the United States (Gunrunner). When put together, there are a couple of elements that make the overall presentation of thi s data more convincing than just some random statistics put together because there was limited time frame, there was a specific set of weapons seized and traced, which applies to all illegal trade, and that the truth of the matter of the arms trade was imprecise. With all that being said, besides all the conditions and uncertainties that the percentages hold in these reports, there is no denying that there is a considerable amount of movement of weapons from the U.S. to Mexico that, to the dismay of many people, find their way into the hands of the people that are involved in this problematic drug trade. The G.A.O. report makes note of the fact that this trafficking is certainly not new to officials on the border, explaining that the U.S. and Mexican government and law enforcement officials did not see any reason why the drug cartels would go through so much hassle and endure the difficult task of obtaining a gun somewhere else in the world and then transporting it to Mexico when it is so easy and so simple for them to do so from the U.S. (Ellington). This proves to be in unison with the reports statement that even though the eTrace data only corresponds to data from the gun trace requests that were turned in from confiscation in Mexico and n ot all the guns seized, it is currently the only methodical and precise data available. Furthermore, the conclusions that the majority of firearms seized and traced were originally in the United States were consistent with the final conclusions reached by U.S. and Mexican government and law enforcement officials personally involved in the prevention and reducing of arms trafficking to Mexico (Cartel). The G.A.O.s data proves to be pretty clear and straight forward in its presentation. Although, the 90% figure that is being brought up constantly in these reports is just an extra number that creates a shock factor to an already stirring issue. Still, while discussions continue as to the appropriate use of this number, the reality is still readily apparent: there is an important and undeniable illegal market of weapons at the U.S.-Mexico border that fuels the violence between different drug-trafficking organizations. In Loreys book The U.S.-Mexican Border into the twenty-First century, he argues that the long-term objective of thinking and policymaking should be to overcome the U.S.-Mexican border (Lorey 12). When he says this, it could mean resolving material inequalities between the two sides of the boundary and more importantly, reducing conflict between the nations. Weapon trafficking is a serious issue that has been lingering for many years, and in order to cooperate with Loreys arguments, the weapons that are short in Mexico need to be dealt with in a different manner. Also, the violent conflicts between the government and drug cartels need to be put to rest. The task at hand may be difficult and long, but there are blueprints to solutions that can be implemented. The main obstacle and challenge that lies ahead in the fight against trafficking, and also where the conversation should be the focus of, is to address the different flaws in the system that ultimately makes way for such arms-trafficking to happen. The G.A.O. report makes not of certain factors that make trafficking possible, including faults and weaknesses found in both the Mexican and U.S. dealings, as well as the system of government: Uncontrolled and universal corruption in the Mexican government; Fragile and weak institutional links and information sharing between A.T.F. and U.S. Immigration and Customs Enforcement (ICE) that lead to incomplete data; The absence of a Spanish language version of the eTrace program to be utilized by the Mexican authorities. Focusing in on these issues will help improve the quality of information being received by both U.S. and Mexican authorities, which can also lead to a much more informed and knowledgeable anti-arms trafficking strategy. This do es not mean that there must be a complete stop in the ongoing actions and efforts to reduce the weapons trafficking, but that the information gathering and collection and sharing between the countries and institutions must get better. There is hope in finding solutions to these weaknesses in the system. In efforts to help improve information collection and sharing, the ATF is hopeful that future funding and increased cash flow will eventually allow for these manuals (eTrace program) to be translated into Spanish, and also to put in a greater number agents on the border alongside an expansion of real-time intelligence sharing between the ATF and the many agents in Mexico. But besides the obviously simple and easy task at hand of translating English to Spanish, the new plans of the Merida Initiative, which is the name of the new proposal brought forth, guarantees to give the Mexican authorities scanners. These scanners, which will be planted at or near the main border crossings, will then be set up completely in order to detect and locate the drugs in traffic moving north and guns in traffic moving south (Mex). There are little things that can change that can help lead to the ultimate goal of reducing the smuggling of these weapons into Mexico, and it is reassuring to hear that after so many years, things are starting to progress and advance in putting an end to a situation that has caused so many problems for so many years. But it is also very important for us not to lose sight of some of the larger issues at hand surrounding arms trafficking at the U.S.-Mexico border. We must keep in mind that in both countries, even with the few restrictions, the weapons markets are legal. And as it applies to all kinds of markets, it is in the interest of those that are involved in the business to keep it alive and running. Being a weapon dealer, especially in the U.S. it is a very vital role they play in the market. For example, according to a 2006 report, the Conventional Arms Transfers to Developing Nations, also known as the CATDN put together and produced by the nonpartisan Congressional Research Service (C.R.S.), which is an office of the Library of Congress, the United States was by far the leading supplier of weapons to the developing world (ATF). Furthermore, in a report that came out in more recent times, the C.R.S. reported that for a 3 year span for the 2005-2008 timeframe, the United States and Russia st ood tall and completely took charge of the arms market in the developing world in the value of arms transfer agreements. These statistics may seem honor worthy and impressive, but when considering the relationship between the U.S. and Mexico, the statistics seem to diminish in value and glory as the weapons that are being brought to Mexico from the U.S. is doing more harm than it is doing good. These reports have also made it clear that is it the eighth consecutive year in a row that the United States has been a leader and top force in worldwide arms deliveries (Gunrunner). And even though the report does not really break down the information for the Latin American region, the report also makes clear note that the U.S. and Russia are the regions two biggest suppliers of these weapons. Even though the U.S. is the world leader in weapons agreements according to these reports, there are indeed other countries that also sell and re-sell weapons. While the data from the reports seems to confirm that the vast majority of these weapons are found and captured in Mexico make their expedition into the country over the U.S. border, it is also most likely that many of these weapons travel through different routes as well. A good number of the arms seized could have also arrived in Mexico through legal transactions that occur time to time between governments but somehow have found their way into the illegal market coincidentally and ultimately into the hands of these drug cartel members. The data from reports may explain general facts and information, but sometimes things can happen without any documentation, and that is where the information gathering and collecting, and addressing of these actions needs to shape up. In conclusion, the ongoing discussion and debate on the U.S.-Mexico border and also on the future of the relationship between these two countries is not an easy one to put to rest or come up with a solution. There are so many important subject matters that are also in need of attention: immigrant migration (legal and illegal), the drug policy, border communications, homeland security, and a mutual environment, just to name a couple. It is clear that, although the tiniest details have the ability to offer a foretaste into the bigger picture, to rely and base the conversation purely on the immediate, just like the debate over Obamas use of the 90% statistic, is to completely lose focus of the much greater and more significant debate that holds the future of a complex and vibrant relationship. The reality of all this is that an illegal arms market is one discussion that fits that description and will be a hot issue for many more years to come until the problem is fixed permanently. In t his circumstance, it is clear that the number of illegal weapons passing through the border every year must be significantly and immediately reduced, and this can only happen through tighter supervision and adjustment of the arms market.

My Brilliant Career at Fuddruckers Restaurant :: Persoanl Narrative Essays

My Brilliant Career at Fuddruckers Restaurant Being called a 'bitch' on the job was becoming more and more an everyday occurrence. After all I did work with four or five guys I liked (males that are rather 'normal' call other males they like the oddest things) and a most unladylike girl who hated me with a severe passion (females that are rather 'unrefined' call people they hate the oddest things.) But today was slightly different. It marked the beginning to the downfall of my employment as Master Burger Flipper at "Fuddruckers"! During the summer I moved away from home. Since I needed money to live I found employment at the only place that would hire unskilled summer work: Fuddruckers Restaurant. Fuddruckers looked like a fun place that I could leave behind at the end of the night and forget about at the end of the summer, as one normally does with summer jobs. But this was not to be. Fuddruckers permanently changed my outlook on several subjects, mainly keeping my mouth shut. First, a description of my co-workers. Ken was the main boss who generally ran the restaurant. Ken was one of those thirty-something guys that still thought he was a senior in high school. He also had the tendency to tell his employees ultra-ultra-sensitive information about his life. Example: in grave detail he one day gave me a rundown of his marriage's apparently rather unfortunate sex life. This was naturally not something I relished being informed of, or -- to be exact -- cared about in any way. His sexual shortcomings were his own problem. My other boss was much the opposite his name was Mr. Metz and if you’ve ever seen the movie Ace Ventura: When Nature Calls he looks exactly like the seemingly evil character Burton Quinn (the one with the raven on his shoulder). He was the owner of the restaurant and was rarely there. When he did make an appearance he neither talked nor showed an interest in many of the employees. But Mr. Metz and Ken did have two things in common. First they never said anything positive to their workers. I worked the entire summer trying my hardest to, as my mother would say, do the job right the first time.

Understanding Black Holes Essay -- Astronomy, research papers

Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years ago. In order to begin to grasp the destructive force of a black hole, one must first understand its creation. Oddly enough, a black hole can only be formed from the death of a star, but no ordinary star can create a black hole; it has to be a super-massive star. Stars consist mainly of hydrogen, and the hydrogen atoms are under such great pressure that they collide and cause a fusion reaction, which creates helium. This constant fusion reaction within the star is what keeps it from collapsing onto itself, thereby sustaining its massive size for billions of years. When a normal-sized star begins to run out of hydrogen, eventually the entire star will begin to run out of hydrogen and the star will actually expand and engulf the inner planets (including earth) before contracting. An average sized star like that of our sun will now become the size of the Earth (Ando, 2004). This is called a white dwarf, and although white dwarves are too dim to be seen from Earth with the naked eye, they doe cont... ... holes die but it takes awhile.
