Women and Film - Essay Example There are several deliberations of how female characters are being depicted in the films. Currently, they have begun assuming more dominant roles in films. Some male film directors use female characters only to provide something against which to express masculinity to male relationships. They are self reflexive for men who design them, as they mostly act as mere guardian spirit for a male protagonist. Often times, they exist as characters to push the storyline along and create some balance instead of getting up on feet on their own. For instance, in Japanese video games Persona 3 where they overtly rent women to draw up the female characters. But this may not be the case for all male filmmakers. For instance, when watching Les Rendezvous D’Anna, you could not imagine a male director design such a female protagonist (Grundmann, 2010). The general observation on female film producers observes women characters for their own interest instead of being a channel to an ideological en d. Female characters designed by women may have scanty clothes that tend to be more real and relaxed looking. They also have petite eyes, sexy features with a maturity on facial expressions. There are fewer women that design action-based films or movies. They mostly make dramatic, comedic, films related to family stories and others that lean more towards an emotional arc. This may be as a result of having little attention on the action-oriented films or the postulation that the target audience wouldn’t put so much interest in them (Walsh, 1986). There is also the issue of the deepness and vigor of female character. One may ascertain the director, but there is also the genre, writer and actress to consider in such cases. Many films made by women have a more exhaustive evaluation of character that is notwithstanding the gender of the directors. In the same way, there are actresses and writers who can yield more dense characters than customary. For instance, Barbara Stanwyck har dly inhabits a character that is not considerably well grasped irrespective of the script or director. The issue involving Godard stretches beyond him as you will find some directors such as Joseph Mankewiecz making films where the actresses appears far more authentic and vivacious than the males. In spite of the themes of the film, they have an unattractive meaning linked to the women’s actions (Callahan, 2012). Other male directors seem to introduce depth in the roles of women. However, that raises eyebrows as to whether those roles are being viewed as another category of male illusion or imaginations. One that originates from a diverse and good direction yet still somehow off the mark likened to the exact experiences of women. The feminist movement relentlessly battled for women’s rights and equality so as to position women on equal grounds to men in the society. This uprising has since been taken forward in the film industry as women also play prominent and conspic uous roles in films. This which was a sharp disparity in the past where women only played domestic roles in the society (Callahan, 2012). At the same time, there are some films that portray women as morally superior and perfect. Dreyer’s Gertrud is an example of such films that convey strength, liberation and empowerment of women. We also have sturdy, irrepressible, self-determining and plausible women in so many films directed by men. This is without indulging in either male fantasies of femaleness or direct sexual appeal (Power, 2009). The role of women in films has since surpassed the traditional feminine characteristics. Women are no longer being portrayed as one-facet who acts stereotypical female traits. In addition, today men are unlikely to measure up to the conventional form of masculinity though they may still

The concepts of empowerment Essay Example for Free

The concepts of empowerment Essay Question 1 Explain the concepts of empowerment, self-managed teams, and cross-functional teams, and develop an essay that argues for their inclusion in either a tall or flat organizational structure. Empowerment is the process of giving employees the authority to make important decisions and to be responsible for their outcomes. Empowerment should exist in tall organizational structure because if the size of the tall organizational structure is bigger is operating process or more tasks appear or tasks become more and more complex, managers at the top of hierarchy will gradually lose the control regarding their work. Self-managed teams reflect self-lead work groups consisting of people who are jointly responsible for ensuring that the team accomplishes its goals. Self-managed teams should exist in flat organizational structure because self-managed teams need to be control well with a few levels to avoid hindering communications. Cross-functional teams are groups of employee from across an organization’s different functions who are empowered to direct and coordinate the value-creation activities. Question 2 Bureaucracy is a phenomenon that presents itself in varying degrees in organizations. When does bureaucracy become a problem in an organization? How can the principles of bureaucracy help managers to design the organizational hierarchy? What can managers do to prevent bureaucratic problems from arising? Bureaucracy becomes a problem when it hampers the work of the organization. When there are too many steps involved and too many people involved to solve issues and make quick decisions, then bureaucracy is a problem. When the hierarchy is inflexible and difficult to wade through, it is a problem. Decisions should not be made without adequate information and time, but when the decisions are bogged down in bureaucratic red tape, the rules and layers of approval, then companies can lose business and opportunities to  act in tune with the market. The principles can help identify the form and the job functions. It helps design the jobs and the technical skills needed to do the jobs so that the best people can be hired to do the job. The principles establish the rules and the focus of the company so there are firm expectations and goals. When all of these are put in place the managers then have the path to follow to create a successful company. Managers must remember that each person is hired because of their skills if the principles are followed. The need for decisions must not be hampered by a top heavy group of decision makers and the rules are in place to guide the decision making process. The hierarchical structure is a form, not a law and when rules and the hierarchical are the only considerations in decision making the systems becomes bogged down and inflexible, or worse, time consuming. In addition, the job and the functions of the company should be impersonal and so should the treatment of employees. Equality is important in an organization. Listening to everyone, accepting diversity in culture, experience, and knowledge can help a company avoid many problems in a bureaucracy.

Internet and Personal Privacy Essay -- Argumentative Persuasive Essays

Internet and Personal Privacy In the world of today most records can be easily accessed by a home computer. Even Governmental records can be viewed. Some believe this has benefits, while others are screaming about invasion of privacy. Heated debates can go on for many hours about this topic. Each side has people who devote all their time and energy to see their side of the argument prevail. The Freedom of Information Act which was established in 1966 states that all people shall have access to federal records. This allows the public to be kept abreast of the workings in the government. Any person may request a document, which the government must present, however, the government can not synthesize a document. It is even possible to order these records on the World Wide Web.

Monster Verses Monster

Today, people still recognize the ghastly, atrocious Frankenstein as a monster, but according to Deems Taylor’s Monster, Richard Wagner is the monstrous beast. Monsters are expected to be frightening like Frankenstein, but some monsters are real humans like Richard Wagner. Oddly, when comparing Frankenstein and Wagner–they certainly share some of the same grim features. Frankenstein and Wagners’ faces manifest a gloomy expression of black death. Their spirit for life lacks warmth in their eyes. Frankenstein’s eyes are hollow and dreary covered with drooping, eyelids, and underneath his eyes are massive sandbags. Similarly, Wagner’s vengeful gaze leers inertly like a frozen statue. Taylor says, â€Å"[he has] a genius for making enemies† (695). The pasty bags (sagging above his cheekbones) are blown up like air pockets. Moreover, they share similar shriveled lips. Frankenstein’s colorless lips are dimly distorted like the mouth of a ruined, porcelain doll. While Wagner’s, sickly, pale lips evoke a spine-chilling eeriness causing most people to shutter; it’s the kind that makes the skin crawl with goose bumps. Undoubtedly, their cold expressions are lifeless, and wicked; however, the size and shape of their heads are equally dreadful. Their large, peculiar, heads resemble a heavy mass wobbling like a bobble head. Their foreheads dominate their gigantic skulls. Frankenstein’s forehead is like a stretched-canvas awning for protection over his eyes. It protrudes along his brow like a piece of metal rod lodged underneath his skin. Likewise, Wagner’s receding hairline emphasizes the size of his enormous skull. According to Taylor, he states, â€Å"[his] head is too big for his body† (693). Furthermore, the structure of their chins is abnormally malformed. Frankenstein’s square chin bulks like a block of wood wedged into his bottom jaw. Its size is the dimension of a small building. On the other hand, Wagner’s narrow, pointy chin extends like an arrow heading for its target. Indeed, the likeness of Frankenstein and Wagners’ massive skulls are laughably creepy. Nonetheless, the magnitude of resemblance is uncanny. All the same, the fearsome expressions on a face or the bizarre proportions of a body can depict a vision of a monster. Frankenstein is a character, created, monster, but Wagner is a real person; a monster in the eyes of Taylor. As attested by Taylor, â€Å"the name of [his] monster [is] Richard Wagner† (695).

Global Climate essays

Global Climate essays The present situation of the global climate and more importantly the action taken to move toward safer environmental prospects is the issue in the sphere of climate change. However, in order to fully understand this topic a brief introduction of the sources of climate change, its subsequent effects and an explanation of why humans should be concerned is necessary. Only after considering that background, can present conditions and initiatives be comprehended to their full importance. Like that of a human, the temperature or climate of the world must be maintained at certain levels in order to sustain life. The Earths climate is a delicate balance between many natural and human forces. Solar energy, climate depends on this factor the most. Although one third of all solar energy is reflected back in space by the Earths upper atmosphere, the two-thirds that do penetrate the Earths atmosphere is the major proponent of weather. The atmosphere itself plays more of an ambiguous role. Cloud formation is a significant component of our atmosphere. It is known to shield solar rays yet still can be guilty of trapping heat in the atmosphere and yet sometimes is also found to let heat escape into space. However unpredictable the overall affect of the atmosphere on the Earths temperature, it does indeed affect it. What is certain about the atmospheres affect is the existence of heat trapping Green House Gases (GHGs), including water vapor, CO2, methane and nitrous oxi de that heat the Earths surface by blocking heats exit. The oceans, covering two thirds of the Earth are a key source of moisture and store heat efficiently as well as transport it across thousands of miles. Another key climate-affecting ocean issue is the carbon-dioxide consuming marine-life that relieves the atmosphere of huge amounts of CO2. The water cycle contributes a cooling effect by supplying water vapor that forms c...

Mistery of the Easter Island essays

Mistery of the Easter Island essays Easter Island is over 2,000 miles from the nearest population center, making it one of the most isolated places on Earth. A triangle of volcanic rock in the South Pacific- it is best known for the giant stone monoliths, known as Moai, that dot the coastline. The early settlers called the island "Te Pito O Te Henua" (Navel of The World). Admiral Roggeveen, who came upon the island on Easter Day in 1722, named it Easter Island. Today, the land, people and language are all referred to locally as Rapa Nui. Unfortunately, there is no written record to help the story of this remote island, its people, and the significance of the nearly nine hundred giant moai that punctuate Easter Islands barren landscape. The moai and the ceremonial sites are along the coast, with a concentration on Easter Islands southeast coast. The moai are more standardized in design, and they have been carved, transported, and erected between fourteen and sixteen hundred. They stand with their basks to the sea and are believed by most archaeologists to represent the spirits of ancestors, chiefs, or other high ranking males who held important positions in the history of Easter Island, or Rapa Nui. The word ahu has two meanings in Easter Island culture. First, an ahu is the flat mound or stone pedestal upon which the moai stand. The ahu is, on average, about four feet high. The word ahu also signifies a sacred ceremonial site where several moai stand. The total number of moai on Easter Island is eight hundred and eighty seven. The largest moai weights approximately a hundred and fifty tons. Several experiments were carried out and although it was proven that the statues could have been moved by rocking and rolling their bases similar to the way we would move a refrigerator or large piece of furniture, the method would have caused so mu ...

Business Communications- Interoffice Memos and the Related Ethics Essay

Business Communications- Interoffice Memos and the Related Ethics - Essay Example Having previously worked with Susan, she is a punctual, committed, hardworking lady to work with and expect the best from her as a member of the committee. It will be a pleasure to have Mark and Kathy included in the committee for their first time and I hope them to be committed and participate to their level best. The party will include all the members of the board, team members, employees and all the other members of staff who have had an association of over three years of the company.Members will interact with the officials of the company and may open valuable information and new opportunities as well. Am looking forward to see you during the meeting, Thank you. One of the primary issues designated in the email is budgeting of the party requirements. For a party event, this is the most significant step as the organizer and for the committee in general as it determines the success level of the event. Reminding the other members of the committee to be punctual and to perform to their level best is significant information included in the email above as it determines whether the objectives of the party will be met. Considering that the party will be a big event for all the members (300 members), there is need to budget and decide on a more suitable place. It is advisable for all the members of the committee to brainstorm on a suitable place in advance and thus make a comparison during the meeting. The venue may include a beach hotel, a restaurant or a park provided it can host at least 300 members and above and within the budget limits. From my own idea, I thought of including some chips, veggies, cookies, sandwiches, popcorns, crackers, bites of fruits, crackers, cheese, and cupcakes. You may also add some other types of food so that we will have a wide range to choose the best and the most enjoyable for the party (Taylor & Gartside, 2004). We will not consider choosing the diet that our members and guests have allergies

The Relationship Between Socioeconomic Status (SES) and Corporal Essay

The Relationship Between Socioeconomic Status (SES) and Corporal Punishment - Essay Example Despite significant support for such broad generalizations, many questions remain regarding relations among SES, parenting, and child growth. The expressions physical punishment and corporal punishment are employed here as synonyms to refer to an action by parents intended to cause the child physical hurting, but not injury, for purposes of correction or control of misconduct. The 1975 and 1985 National Family Violence Surveys discovered that about 95% of American parents use corporal punishment as just cleared. This is consistent with a large number of other studies (Straus, 1991) and with the faith that corporal punishment is used by parents with tots or young children. Public health advocates have described corporal punishment as "a form of interfamilial violence associated with short and long-term adverse mental health outcomes" (Stewart et al., 2000, p. 257). Corporal punishment in the United States presents a complex picture, with high but decreasing rates of general approval, and a population increasingly divided regarding its use (Straus & Mathur, 1994). The approval of corporal punishment in the United States decreased dramatically from 94% in 1978 to 68% in 1994 (Straus & Mathur, 1996). Whereas in 1978 there was almost universal approval in the United States for parents spanking children, regardless of demographic variables, by 1994 disagreements were evident, with greater approval noted among African Americans, Southerners, and those with fewer years of formal education (Straus & Mathur, 1996). Unfortunately, data concerning Latinos are limited. Frequently, Latinos are simply excluded from the sample or are miscoded as African American or White (Ortega, Guillean, & Najera, 1996). The actual use of corporal punishment in the United States is also decreasing (Dart & Gelles, 1992; Straus, 1994). Even so, corporal punishment is still used widely, and Giles-Sims, Straus, and Sugarman (1995) have reported that "almost all children in the United States are spanked by their parents at some point in their lives" (p. 170). For parents to give up corporal punishment, they need to establish an effective alternative system of instruction and discipline. Research supports the notion that three kinds of parenting behaviors constitute such a system: those that promote the parent-child relationship, those that reinforce positive behaviors, and those that decrease undesired behaviors (Howard, 1996). Parents who resort to frequent or severe corporal punishment are likely to rely too much on punitive techniques, without using the other methods. They may underutilize other ways to gain compliance: through building their relationship with their children, reinforcing positive behaviors, and decreasing undesired behaviors through means other than punishment (e.g., distracting the child). Male gender, lower socioeconomic status, comorbid analysis of ADHD, positive parental history of mental illness

Global & International Business Contexts (Chilean wine industry) Essay

Global & International Business Contexts (Chilean wine industry) - Essay Example The highly competitive environment in the telecommunication sector has led to low pricing of the communication services that has reduce the cost of the business infrastructure for companies in Chilean markets (William,  Beaujanot  and  Zuniga, 2010). The administrative infrastructure has also been favourable for quick registrations reduced the time of obtaining licences for the new companies entering the wine industry (Rugman and Collison, 2012). The physical infrastructure in Chile supports the growth of wine industry as the country has high efficient air port and sea port facilities to support the distribution of wine. The government has always encouraged development of skills of the available manpower. This has been advantageous for the Chilean wine industry as the efficiency of the workforce is closely linked to the business output (Wines of Chile, 2013). The weakness of the Chilean conditions lay in the lack of good quality of education at various levels in the education s ystem. The government has been coordinating for laying the infrastructure of proper training and development, specialized training for certain industries like the wine industry to provide favourable business environment for the investors. The wine industry of Chile, however, faces the risk of natural disaster like earthquake, volcanoes, etc. Due to these disasters, the wine industry has faced million dollar losses as a result of the damages on the physical infrastructure like the airports, transport facilities, etc. However, the overall industry environment supports adequate level of production to meet the export requirements of the wine industry. The foreign currency regulation is weak in Chile due to which the wine... The strategies and the rivalry prevailing among the wine producers in the Chilean wine markets are also important for analysing the Chilean wine industry. The level of competition in the Chilean wine industry in quite healthy in nature that has the objective of producing quality wine products for supplying to the customers in domestic and foreign markets (Jenster, Hayes and Smith, 2005). The Chilean wine industry has witnessed strong regional competition among the wine producers. Due to the high prospects and the lucrative business opportunities in the wine industry of Chile, there have been foreign direct investments in this sector. The foreign investors have increased their presence in the Chilean wine industry thereby increasing the competition for the production of good quality of wine at competitive prices. The instances of joint ventures have also been noticed in the wine industry. The joint venture between Err azuriz and Mondavi is an example. Thus the competitive rivalry in t he wine industry has been quite intense which led to the increase in performance of wine production and supply over the years. The areas of weakness of the wine industry are also important to analyse the investment proposal of the new business. The wine industry of Chile lacks in the area of governance among the wine producers and suppliers operating in the market (Visser and Langen, 2006). The wine producers and the suppliers lack mutual trust among each other. The practise of copying the marketing and distribution styles of other players has been observed. The Chilean wine industry has shown signs of regional differentiation.

Ostpolitik And Its Influence Between The US And USSR Essay

Ostpolitik And Its Influence Between The US And USSR - Essay Example The Nixon administration was unconvinced about Brandt’s Ostpolitik and a firm stance on Germany was difficult to achieve. Kissinger eventually accepted the US’s limited authority on the dà ©tente in Germany but did attempt to influence it through talks over Berlin’s status. Nixon’s acceptance of the dà ©tente was motivated by tactical reasons rather than to develop a relationship with the Soviets (Gates 2004). Although the US cast doubts on Ostpolitik, its ramification was felt long afterward. The US felt that more comprehensive dialogue with the Soviets was possible and during the period the two superpowers went through a phase of cooperation. Yet the cold war refused to go away. Their rivalry influenced global politics with each attempting to insert their ideology in European and other nations around the world. States which were not directly united with either the US or Soviets started the Non-aligned movement but were pawns in the hands of the superpo wers who tried to win their support through economic and military aid. Despite the competition between the superpowers, negotiation between the US and the Soviets improved in the era of dà ©tente which was occurring as a result of Brandt’s Ostpolitik. Increased cooperation led to the Strategic Arms Limitation Talks (SALT) in 1972 and 1974 where both powers initiated a long process spanning decades of reducing their military armaments. Ostpolitik was a precursor to the Helsinki Accords where the US and the Soviet Union along with 32 other European nations.... One of the measures to do this was to abandon the use of force in any dispute and resolve issues by diplomatic negotiations. The other element of Brandt's Ostpolitik was the recognition of the Oder-Neisse Line as the actual border between Poland and Germany. This border meant Poland took some of German territory thereby displacing millions of Germans from this area (Pittman 1992). The effect of Ostpolitik was that displaced East Germans were able to make visits to Poland and reunite with family and friends. The treaty did not change the duties of the four powers governing Germany and maintained the commitment of West Germany towards future unification. Brandt's Ostpolitik also aimed at improving relations with the Soviet Union and Poland but this policy created divisions among the people. Two camps with opposing views on Ostpolitik had formed. The policy was especially unpopular among the victims of ethnic cleansing in East Germany who decried it as illegal. Moscow too was sceptical about openings between West and East Germany and wanted to control it (Wolf 1999). The other camp commended the policy as creating change through rapprochement or a process of developing healthy relations rather than maintaining seclusion. The process of rapprochement was aided by socialist government expectations that a West German Social Democratic management would comprehend the situation more. Ostpolitik did encourage the gradual waning of the siege mindset present with East Germany and improve the recognition of the economic system operating within each state. Ostpolitik also differed ardently with social democrats and conservatives. When the soviets agreed to open negotiations on the Berlin situation, the Treaty of

The Role of Religious Accommodation at Workplace Essay

The Role of Religious Accommodation at Workplace - Essay Example In General, people in the modern world is spending most of their life time in offices and workplace is a significant environment in their life. The modern century is functioning at a fast space and everyone wants to perform their best at their workplace in peace with his inner self. An employee who keeps his religion alive can inculcate enormous ethics, moral and social values in him. In the same way religious accommodation are essential at work place as it increases the quality of job performance and productivity among employees. As per (Laderman) â€Å"Today, "religion" can mean anything at all, from the most personal and intimate spirituality for the individual to the most diffuse cultural activity in any given society†. Religious values increases work quality First when we think about religion, the most important factor that sweeps through our mind is the serenity and satisfaction it brings to the psyche and personality of an individual. As all know ,religion is the direct ion towards God and anyone engaged in this value is at peace .It is obvious that when the self of a person is at serenity he can bring forth vitality to his thinking and personal behavior despite of the environment he is in. Work place environment is mostly stress abandoned and employees undergo much complication and emotional disturbance, when they engage in work place. So it will be greatly benefited on individual basis if the organizations allot some time to the employees for religious practice. According to (TriNet)â€Å"A Gallup poll states that 90% of American adults say that religion is either very important or fairly important in their lives. And with that, arises workplace conflicts†. Frankly speaking, religious accommodation is important in workplace as it increases the confidence and mental balance of an employee which results in quality job performance and productivity. Only a spiritually evoked employee can regulate his behavior and thoughts and give out optimum potentiality to the organization he/she is working in .In an organization, there can be present people from various religious background. However when an employee engage in his/her religious practice , he connect with God and respect all religions and treat his colleagues with respect and humility. Religion can bring about conflict at work place and time management issues Religion indeed is an essential part of every individual’s life , but as there are different religion in world , the ideology and religious culture in a work place vary immensely. This fact can give rise to conflict among employees as their habit and behavior differ according to their religious concept and beliefs. This contradicting view among employees can lead to chaos and dysfunctional situation. When employees hold vengeance and unfriendly attitude among each other, the flow of business can be interrupted and this can create low quality work and unproductive situation in workplace Generally, failure and lockouts can occur in work place and dealing with this issue can create loss of time. When the employees of an organization hold various religious beliefs then the organization can work on a not unifying nature . This is because the employees on various level look at each other as opponent and enemies and they can feel like competing with each other to prove each one’s religion as the best. Such an atmosphere can dismantle the whole unifying environment of the organization.

The policy was especially unpopular among the victims of ethnic cleansing in East Germany who decried it as illegal. Moscow too was sceptical about openings between West and East Germany and wanted to control it (Wolf 1999). The other camp commended the policy as creating change through rapprochement or a process of developing healthy relations rather than maintaining seclusion. The process of rapprochement was aided by socialist government expectations that a West German Social Democratic management would comprehend the situation more. Ostpolitik did encourage the gradual waning of the siege mindset present with East Germany and improve the recognition of the economic system operating within each state. Ostpolitik also differed ardently with social democrats and conservatives. When the soviets agreed to open negotiations on the Berlin situation, the Treaty of

Income Inequality - Essay Example The main reason he foresaw an evolution was due to the recurrent nature of income inequality. In an income inequality situation, the richer keep getting richer due to a better income, while the poor keep getting poorer. The gap between the top earners and the low-income earners keeps widening in an income inequality situation. In America, almost 95% of the national wealth is under 5% ownership; this situation leaves 95% of the population to scrounge for the limited 5% wealth (DeNavas et. Al, 2005). For economic inequality study, a family makes the ideal study unit. In the study, the family’s income is under analysis, and then the family members ranked from the lowest income earner to the highest income earner. After the ranking, the incomes aid in establishing a Lorenz curve that is important in analysis of income. In order for a Lorenz curve to be correct, the incomes of the family members have to be divided into fifths (Lorenz, 1905). A Lorenz curve enables analysis of data by adding the percentage value of the lowest fifth to the next higher fifth, which becomes the first point of the curve. The second point in the curve comes about through adding the first point to the middle fifth of the derived incomes. The process of plotting continues until exhaustion of all cumulative values of member incomes (Lorenz, 1905). For a perfect Lorenz curve, all members in a family would earn the same amount and the Lorenz curve would be a diagonal with the lowest point being the lower left hand corner moving progressively towards the higher right hand corner. This diagonal shows an ideal situation and it is the baseline in determining income inequality. Since not all family members receive an equal income, the Lorenz curve turns out as a curve instead of a diagonal. The area between the curve and the diagonal dictates the measure of inequality from one member of a given family to the next member (Lorenz, 1905). Income

Trade Liberalization Essay Example for Free

Trade Liberalization Essay Trade is very critical in any country as it ensures that although countries have different production capabilities they can acquire all types of goods. Different capabilities arise due to the fact that different countries have different natural resources, educational capabilities, varying physical capital as well as the technological knowledge. Trade liberalization entails the reduction of limitations on trade across countries. Artificial barriers as well as other forms of distortions are reduced. (Alvarado S and Morici P, 1992, 59). Protectionism is completely eliminated and tariffs which entail the raising of import prices, quotas that see to it that there is physical limitation on goods that can be imported as well as non tariff barriers like regulation and legislation that hinder easy entry for foreign competitors are eliminated. The US is committed to ensuring that countries eradicate barriers as is seen through its efforts in General Agreement on Tariffs and Trade (GATT) and World Trade Organization (WTO) and in Free Trade Area (FTA).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Trade liberalization or policies ensure that economies are open to trade and investments with the rest of the world. It is crucial for any nation if sustained economic growth is to be attained. Free trade ensures the creation of jobs, better working conditions and the over all economic growth. No country can attain economic growth, which comes along with improved standards of living if it is in exclusion with the rest part of the world. In other words, no country is self-sufficient. Trade openings as well as foreign direct investment ensure economic success especially in third world countries. Trade liberalization has seen many third world countries develop competitive advantages in the production of certain products thus increasing their production and consequently increasing the profits derived from them. This has seen the number of people living in the margins of poverty decrease. It is evident that countries focus on the outward development rather than inward developments thrive more. Such countries focus more on the interrelated relationship with other countries and together all the parties involved benefit. Countries as India, Vietnam and Uganda are relevant examples of how faster growth and poverty reduction is realized when trade liberalization takes place. Lowering of tariffs comes along with quick growth compared to those who do not. (www.kent.ac.uk).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Trade liberalization benefits the poor more. Protection is associated with large implicit subsidies that most third world countries cannot afford. Liberalization of trade ensures that the poor people‘s incomes increase with almost the same proportion as the total population as a whole increases. With trade liberalization there is the creation of jobs, which can suit the semi and the unskilled workers in a nation, such a move, ensures their graduation from a lower social status to a higher one. Again, the reduced inequality gap that had been observed since the 1990s was partly due to trade liberalization and its effects on the economic growth. More gains can be accrued if many barriers to trade are eliminated. Third world countries are more likely to benefit from trade liberalization as a percentage of their GDP than the developed countries since their economies tend to be more or highly protected and also because they face more barriers. (www.imf.org).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     To maximally leap the benefits of trade liberalization it is important that countries specialize in producing goods that they have a comparative advantage in. The opening of their markets and ensuring that their companies compete internationally then follow this. This necessitates stiff competition and increased efficiency that ensures that prices go down making the goods more attractive and affordable. Demand consequently rises and there is continued or increased production to match it. As the businesses, boom the Gross National Income rises and all people benefit from it.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Trade liberalization encourages or facilitates the increased imports of strategic goods and services, attracts foreign direct investment and enhances technological transfers. It also ensures the development of endogenous capacities as well as the development of infrastructure that is appropriate to support national objectives for industrial development.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     It can indirectly be beneficial to a country’s natural resources as with the increased trade, countries can acquire the finances needed to support environmental protection, its conservation as well as remediation efforts. Although there are potential negative effects associated with trade liberalization policies that promote the positive effects ought to be enhanced. It is also important to ensure that institutional as well as human capacities of developing countries or those that are in the transition process to the market economies are well organized. This would ensure effective integration between the environment, trade and development policies. Negative effects or impacts of trade should be avoided and curbed before they even emerge and once they start being manifested, they should be addressed quickly. It is important to take into account the sustainability of a country’s environmental as well as natural resources when designing the trade liberalization policies. This will go a long way in ensuring that there are fewer or no adverse effects. In Bangladesh, the shrimp culture became beneficial with the introduction of liberalization. The economic gains included the increased GDP that recorded an increase of approximately 70 %. Exports increased and there was the increased employment rate for the locals.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Copper mining in Chile also benefited from trade liberalization. It saw the increased GDP from the sector. The sector contributed to the country’s total exports to a tune of 41% despite the fact that it created employment for just a few people. The liberalization ensured that there was increased private participation and this meant that efficiency and effectiveness would be enhanced. New technologies could easily be adopted and they ensure that costs of production were lowered, competitiveness increased and it was possible to explore previously marginalized areas. (www.kent.ac.uk). This is crucial in ensuring that rural development is attained. Diversified economic development is vital for third world countries as it reduces the rural urban migration and ensures rural development. Infrastructures are developed in areas that could have remained under developed as third world countries lack adequate capital to ensure unified development.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Liberalization enhances competition which works to increase innovation and exploration. It ensures that there is effective exploration especially in areas that had previously been marginalized. It also encourages the use of environmentally friendly technologies geared to ensure that there is minimal harm to the environment. With increased exports or trade in general there is the generation of foreign exchange, attraction of external investment and the creation of employment.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Free trade ensures that there is the creation of trade and domestic production is substituted with cheaper imports. Trade creation is important as it ensures that there is effective production efficiency. (Peloso J, 2005, 154). Factors that determine the effects on trade depend on whether there are lower prices due to tariff reduction and if the price changes are responsive to the supply and demand in the market.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Trade liberalization can be defined as a form of trade where a neutral approach is taken and there is minimal government control. Most developing countries that register minimal growth had a history of poor implementation issue in totality.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Trade liberalization and free trade ensures positive externalities that lead to increased or greater competition that ensures there is much efficiency in resource allocation, economies of scale as well as technological spill over effects. It reduces rent seeking – behaviour and promotes the increased flow of technological knowledge across the globe. There is a greater access to new goods be they capital or intermediate. There is also a faster rate in the imitation of advanced techniques that enable third world countries to prosper economically.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     It makes exports more competitive especially in the international markets since it involves the reduction in exchange rates distortion as well as export duties. Trade liberalization and free trade in third world countries ensures that there is export diversification among countries involved. Trade restrictions that hinder or act as an obstacle to trade are erased.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Some third world countries especially in Africa would greatly benefit from increased trade through trade liberalization. Most of them have poor infrastructure that would need huge capital to develop in trying to increase the rates of production. Their inadequate capital makes them it hard to acquire new and more efficient technology needed to ensure that there is considerable economic growth and development. Others are inhibited by their geographical locations in ensuring that they develop economically. With trade liberalization acquisition of goods that land locked countries like Uganda is made easier. Many gains are earned when countries exploit their comparative advantage in the face of free trade and trade liberalization.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     History proves that inward development among the third world countries where their governments intervene or control the economy are not effective in ensuring economic growth. In the 1960s and 70s when this approach was used it was characterized by ineffective or deficient infrastructures, underdeveloped financial markets as well as poor human capital resources. Through trade liberalization, it was possible to acquire external finances that would steer up the economy.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     The overall effects of trade liberalization are highly correlated to a country’s political, economical as well as social organization. It is also affected by the way reforms are created and implemented for instance reforms on import liberalization and the approach that is taken for example through tariff reduction, structure unification or reduced duty rates.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     In Tunisia, trade liberalization enhanced export promotion that created changes in the country’s economic growth and external payments. Import liberalization saw the promotion of domestic production that strengthened competition and consequently the economy’s efficiency was enhanced. It ensured trade competition with neighboring countries like Morocco, Algeria and Egypt. Liberalization of telecommunication sector made significant changes in the country’s economic development. Economic expansion in the country is also attributed to the increased privatization of most sectors making them more efficient and effective.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Trade liberalization can be of much importance to third world countries especially because through trade agreements there is the enhancement of the rule of law among the countries involved. Good governance, transparency as well as fair enforcement of contracts is ensured in the countries involved. (Wallace L, 1999, 89). Corruption is in most case eradicated as the rule of law is reinforced and it promotes foreign direct investment. Property rights are also empowered and they ensure that there is effective investment in the involved countries. This ensures that there is increased savings as well as investment and exchange. The competition that comes along with free trade benefits the poor especially in the third world countries where they are susceptible to exploitation by the elites or by a few monopolies. It promotes equality and eradicates the manipulation of trading activities. Free trade also encourages reforms in various sectors of the economy and consequently promotes growth. It sees to it that there is efficiency as the policies established are critical. Again democracies can be effectively strengthened with the establishment of free trade. Free trade in addition to promoting the flow of goods and services it also entails the transmission of ideas and values. Self confidence is therefore ensured as freedom is ensured.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     The World Bank reported of the overwhelming growth that came along with the reduction of trade barriers, it estimates that in the 90s the per capita of such countries rose by almost thrice. (www.usemb.gov.do). Trade liberalization encourages domestic reforms that are needed in third world countries. Freedom and openness promote effective governance and macroeconomic policies that ensure there is economic growth. The economic gains arising from increased trade would be effective in ensuring that third world countries reduce the burden of seeking foreign assistance that comes with strings attached or conditional ties.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     According to the numerous studies conducted by World Bank and also by the University of Michigan there are more gains attributed to trade liberalization especially in developing countries where trade barriers are approximately four times more than in developed countries. Another study by International Institute of Economics established that millions of people subjected to abject poverty especially in the third world countries would have their living standards improved with the global free trade. (www.usemb.gov.do). Trade liberalization and free trade therefore increases the flow of trade and benefit the third world countries. References: IMF. 2001.

Support Vector Machine Based Model

Support Vector Machine Based Model Support Vector Machine based model for Host Overload Detection in Clouds Abstract. Recently increased demand in computational power resulted in establishing large-scale data centers. The developments in virtualization tech-nology have resulted in increased resources utilization across data centers, but energy efficient resource utilization becomes a challenge. It has been predicted that by 2015 data center facilities costs would contribute about 75%, whereas IT would contribute the remaining 25% to the overall operating cost of the data center. The Server consolidation concept has been evolved for improving the energy efficiency of the data centers. The paper focuses on support vector machine based novel approach to predict the overload and underload pattern of the servers for better data center reconfiguration. Keywords: Support vector machine, energy efficiency. 1 Introduction Virtualization plays an important role in cloud computing, since it permits appropriate degree of customization, security, isolation, and manageability that are fundamental for delivering IT services on demand. One of its striking features is the ability to utilize compute power more proficiently. Particularly, virtualization provides an opportunity to consolidate multiple virtual machine (VM) instances on fewer hosts depending on the host utilization, enabling many of computers to be turned-off, and thereby resulting in substantial energy savings. In fact, commercial products such as the VMware vSphere Distributed Resource Scheduler (DRS), Microsoft System Center Virtual Machine Manager (VMM), and Citirix XenServer offer VM consolidation as their chief functionality[1]. But with the rapid growth in computing demand, the number of datacenters grows with the need which leads to more number of servers active at a time. The high active servers’ ratio leads to more energy emission and production of Carbon dioxide (CO2). According to data centers’ study, the data centers are not utilized up to their maximum utilization level which leads to more active servers, everyone utilized to less than their total capacity. With this in mind, it is worthwhile to attempt to minimize energy consumption through any means available. Various research agencies and universities have contributed into the research and design of heat dissipation and control in the data center. Virtualization is a technology that contributes to the maximum u tilization of the servers by virtual machine (VM) consolidation and VM Migration. The decision of reallocation of virtual machine for VM consolidation depends on the host utilization behavior. The VMs from the under-utilized and over-utilized hosts are relocated to other hosts by packing the VMs on minimum number of hosts. The hosts having no virtual machine are shifted to the passive mode so that the total energy consumption can be reduced. Statistical methods played a great role in predicting the behavior of the host in dynamic manner. The author [3] has proposed various statistical methods for host overload and underload behavior of the hosts in his thesis. These algorithms take input as the previous or current utilization of the hosts and predict the future based on the previous or current state of the system. He has proposed Local Regression, Median Absolute Deviation, Robust Local Regression and Markov Chain model for predicting the overloaded hosts [3]. All statistical models cannot be applied to all the environments. The choice of the statistical methods d epends on the input data, because every statistical model is based on some assumptions. Markov chain model assumes that the data will be stationary but complex and dynamic environment like cloud, experience highly variable non-stationary workload. The author [3] in his thesis modified his model by using multisize sliding window workload estimation method so that it can be suitable for the cloud environment. In this paper we have proposed a prediction based model i.e. Support Vector Machine (SVM) to predict the host utilization to forecast the host overload and underload behavior of the host. The rest of the paper is organized as follows. Section 2 explains the basic concepts and modeling approaches of the Support Vector Machine. In section 3, the literature review related to Support Vector Machine is presented. In section 4 the model is applied to time series forecasting and its performance is compared with those of other forecasting models. Section 5 contains the concluding remarks. 2 Support Vector Machine Support vector machine is a novel technique based on neural network invented by Vapnik and his co-workers at AT T Bell Laboratories in 1995. The objective of SVM is to find a generalized decision rule through selecting some particular subset of training data, called support vectors. Training SVMs is equivalent to solving a linearly constrained quadratic programming problem. The quadratic equation is solved such that the solution of SVM is globally optimal and the quality complexity of the solution does not directly depend on the input space. Another key advantage of SVM is that SVMs tend to be resistant to over-fitting, even in cases where the number of attributes is greater than the number of observations. According to Vapnik there are three main problems in machine learning, e.g. Density Estimation Classification and Regression. In every case the main goal is to learn a function (or hypothesis) from the training data using a learning machine and then conclude general results base d on this knowledge. Time series is a series of data points S t à ¯Ã†â€™Ã… ½ R usually ordered in time. Time series analysis comprises the methods for analyzing the time series data in order to extract meaningful statistics and other characteristics of the data. Time series forecasting models predicts future values based on the previously observed values. The main focus of this paper is to predict the overload and underload behavior of the hosts in cloud data centers based on the previous load pattern of the hosts in the datacenter. The time series prediction is affected by various factors like data is linearly separable or follows non-linear patterns, the learning is supervised learning or unsupervised learning and on support vector kernels. In Euclidean geometry linear separability is a geometric property of a pair of sets of points. The points are linearly separable or not are decided by visualizing the points in two dimensions plane by taking one set of points as being colored green and the other set of points as red. These two sets are linearly separable if there exists at least one line in the plane with all of the green points on one side of the line and all the red points on the other side. Usually in practical problems the data points are mapped to the high dimensional plane and the optimal separating hyper plane is constructed with the help of some special functions known as support vector Kernels in this new feature space. This method also resolves the problem where the training points are not separab le by a linear decision boundary. Because by using an appropriate transformation the training data points can be made linearly separable in the feature space. Figure1 (a) Linearly separable data1(b) non-linear patterns of data In supervisory learning, the training data is composed of input as well as the output vector (also called supervisory signals) whereas in un-supervisory learning the training data is composed of only input vectors. Supervisory learning produces better results because the output vector is already known and the predicted values by the SVM are compared with the output to learn better for the next step. In un-supervisory learning the output data points are not known and the training depends on the probability to drive better results out of it. SVM comes in the supervisory learning category and the kernel function makes the technique applicable for the linear as well as non-linear approximation. 3 Related Works In various practical domains time series modeling and forecasting has essential importance. A lot of research works is going on in this subject during several years. Many models have been proposed in literature for improving the accuracy and efficiency of time series modeling and forecasting. The author [1] has compared various time series prediction methods widely used these days. This paper investigated the application of SVM in financial forecasting. The autoregressive integrated moving average model(ARIMA), ANN, and SVM models were fitted to Al-Quds Index of the Palestinian Stock Exchange Market time series data and two-month future points were forecast. The results of applying SVM methods and the accuracy of forecasting were assessed and compared to those of the ARIMA and ANN methods through the minimum root-mean-square error of the natural logarithms of the data. Results proved that svm is better method of modeling and outperformed ARIMA and ANN. The author of [2] explains the time series concept and the various methods of predicting the future values based on ARIMA model, Seasonal ARIMA model, ANN model, time lagged ANN, seasonal ANN, SVM for regression, SVM for forecasting etc. they have also explained the forecast performance measure MFE (Mean Forecast Error), MAE (Mean Absolute error), MAPE (Mean absolute percentage error), MPE (Mean percentage error), MSE (Means squared error) etc. In paper [5], a model based on least squares support vector machine is proposed to forecast the daily peak loads of electricity in a month. In [5] the time series prediction was first used to forecast electricity load .In paper [4] the author has improved the method presented in [5] to derive more accurate results. The author has proposed dynamic least square support vector machine (DLS-SVM) to track the dynamics of nonlinear time-varying systems. The dynamic least square method works dynamically by replacing the first vector by the new input vector to obtain more accurate result.. The author in paper [9] has proposed the modified version on svm for time series forecasting. The algorithm performs the forecasting in phases. In the first phase, self-organizing map (SOM) is used to partition the whole input space into several disjointed regions. A tree-structured architecture is adopted in the partition to avoid the problem of predetermining the number of partitioned regions. Then, in the second phase, multiple SVMs, also called SVM experts, are constructed by finding the most appropriate kernel function and the optimal free parameters of SVMs. 4 Support Vector Machine Regression Formulations for Forecasting Host Overload Detection Host overload and underload detection is based on current utilization patterns of the host. The host utilization is a univariate time series. In univariate time series the future values are entirely based on past observations. The goal of the SVM regression is to find a function that presents the most deviation from the target values so the maximum allowed error is. The future values are predicted by splitting the time series data into training inputs and the training outputs. Given training data sets of N points, with input data and output data . Assume a non-linear function as given below: (1) w = weight vector, b=bias and is a non-linear mapping to a higher dimensional space. The optimization problem can be defined as: : (2) is a user defined maximum error allowed. The above equation (2) can be rewrite as: : (3) To solve the above equation slack variables needs to be introduced to handle the infeasible optimization problem. After introducing the slack variables the above equations takes the form as given below: : (4) The slack variables defines the size of the upper and the lower deviation as shown in the figure 2(a). Figure 2 (a) The Accurate points inside Tube 2(b) Slope decided by C For simplicity and for avoiding the case of infinite dimensionality of the weight vector w the optimization operation are performed in the dual space[4] the Lagrangian for the problem(a) is given by [2] (3) Here, where are the Lagrange multiples. Applying the conditions of the optimality, one can compute the partial derivatives of L with respect to equate them to zero and finally eliminating w and obtain the following linear system of equations (4) Here, and with is the kernel matrix. The LS-SVM decision function is thus given by [4] (5) The dynamic least square support vector machine is modified so that it is best suitable for the real world problems. The key feature of DLS-SVM is that it can track the dynamics of the non-linear time varying system by deleting one existing data point whenever a new observation is added, thus maintaining the constant window size. 4 Experiments We have used CloudSim for retrieving the utilization of the host based on the workload defined in the PlanetLab folder in CloudSim. It contains the daily virtual machine requirement and the utilization of the host is calculated based on the daily requirement of the virtual machines. After retrieving the utilization of the hosts LSSVMLabv1 toolbox is used for support vector regression and the results are compared with [10] and [5]. The comparison is based on MAPE (mean absolute percentage error) and Maximal error (ME). The chart shows that DLS-SVM produce better forecast for the load pattern of the hosts in the data centers.

Statistical Handling Data Coursework on High School Students Essay

Statistical Handling Data Coursework: High School For this handling statistical data coursework I will be investigating the heights and weights of students of years 7 to 11 in High School. Although this is a fictitious school the data is based on a real school. I will look for a trend in the heights and weights of the students to see if the taller they are, the more they weigh. This is my hypothesis. My Null hypothesis is that there is no correlation between height and weight, and my Alternative hypothesis is that there is strong, positive correlation between them. I will then investigate the heights of boys in years 7 and compare them to the girls, and then do the same in year 11. I will then be able to compare these two sets of results. These are my second and third hypotheses. I am carrying this investigation out because from my hypothesis I want to know whether students in the older years should be separated from the younger students in the lunch queues. This could be necessary because if the taller students are heavier, then the shorter ones will get hurt in the queue to lunch since students usually push their way to the front. So if the taller students are the older ones, then the year groups should be separated in the queue in order to prevent anyone getting hurt. In order to carry out this investigation, I will need to collect the heights and weights of all the students in High School between and including years 7 to 11. Instead of collecting the data, I can find the information on an exam board website. This data is reliable because it is provided by the exam board and is based on real students, however, it may be unreliable because it is secondary data, not primary since I am not physically collectin... ...rect guesses. They also provided a lot of inappropriate data such as their names which is inappropriate since isn’t worth investigating. The data could be biased because it was only collected from one school and not from other areas in the country. The data may be biased because there may have been a lot of snack shops or fast food restaurants near the school, which may have affected the students’ weights. I could have investigated further by using more than one school’s data and compared them and I could have had more hypothesise. This would have given more precise results due to a larger range and a larger sample. I could have drawn more graphs and made more calculations to get more accurate results. For example I could have calculated the standard deviation for my three hypothesise to get a more accurate spread of data than the interquartile range.

Commander of the Faithful: The Life and Times of Emir Abd el-Kader Essa

The life of Amir Abd el-Kader was marked by a litany of difficult decisions— questions of whether to respond to violence and oppression strongly or weakly, to remain unyielding in retaliation or to surrender and, in doing so, stop unnecessary death. Upon closer analysis, the challenges and decisions which confronted the Amir are not so drastically different from more modern concerns of international intervention or political upheaval. In reading of the Amir’s life and prior to this, the Ghost Dance of the Lakota people and the development of the Khalsa in the Sikh religion, there has been a desire to identify and separate religious responses to suffering from other, equally legitimate but perhaps more seemingly political, economic, or militaristic responses. This categorization is useful for a society that has, since the enlightenment, become increasingly compartmentalized, ever seeking to separate actions and responses according to their perceived motivations.

Commander of the Faithful: The Life and Times of Emir Abd el-Kader Essa The life of Amir Abd el-Kader was marked by a litany of difficult decisions— questions of whether to respond to violence and oppression strongly or weakly, to remain unyielding in retaliation or to surrender and, in doing so, stop unnecessary death. Upon closer analysis, the challenges and decisions which confronted the Amir are not so drastically different from more modern concerns of international intervention or political upheaval. In reading of the Amir’s life and prior to this, the Ghost Dance of the Lakota people and the development of the Khalsa in the Sikh religion, there has been a desire to identify and separate religious responses to suffering from other, equally legitimate but perhaps more seemingly political, economic, or militaristic responses. This categorization is useful for a society that has, since the enlightenment, become increasingly compartmentalized, ever seeking to separate actions and responses according to their perceived motivations.

‘Lord of the Flies’ by William Golding Essay

‘Lord of the Flies’ by William Golding describes a group of schoolboys’ means of life when they become stranded on a desert island after a plane crash which killed all other passengers and crew, with only vast jungle and sandy shores around them. During their unusual experience, one of the main characters – Ralph – learns thing about himself and the others that no other twelve year old would ever imagine. With â€Å"a mildness about his mouth and eyes that proclaimed no evil†, Ralph seems the laid-back sort, confident and trustworthy. Although when he first meets Piggy, another schoolboy, this all changes and the immaturity of a typical child of his age shines through. When finding out that his new friend used to be nicknamed ‘Piggy’ as a result of his short and fat appearance, â€Å"he dived in the sand at Piggy’s feet and lay there laughing.† Ralph thinks of Piggy as a paranoid wimp, and relishes in the fact that they have a whole island to roam around on, with no grown-ups to tell them what to do. Piggy, however, instantly realises the severity of what has happened, and panics at the thought of the future: â€Å"We may stay here till we die.† As far Ralph is concerned, the island is paradise. He is glad when he meets Jack, another one of the bunch of schoolboys with an obsession for hunting, but who is out to have fun on the island. Things get off to a good start, but when their new way of life descends into disaster, Ralph’s relationship with Piggy grows as it comes clear that Piggy is actually a very wise person, and Ralph’s relationship with Jack turns to rivalry, Ralph finds himself having to grow up quickly and reinforce his position as leader to restore civilisation – a fast fading luxury: â€Å"We need an assembly. Not for fun†¦..but to put things straight.† When Jack becomes fed up with Ralph’s rules and leadership tactics, he decides to break away from the crowd and forms his own tribe of ‘hunters.’ By this point Ralph grows aware that trying to persuade them to stay with his tribe, he is fighting a losing battle, and discovers that he may not be as good a leader as he thought he would be: â€Å"Only, decided Ralph as he faced the chief’s seat, I can’t think. Not like Piggy.† The death of Simon, a quiet, subdued fellow schoolboy, really disturbs Ralph, as he faces up to reality. Simon’s death was a consequence of Jack’s tribe getting overexcited about â€Å"the beast† and was a mistaken identity case involving the beach, many spears, and a chorus of youngsters wildly chanting â€Å"Kill the beast! Cut his throat! Spill his blood! Do him in!† The realisation of the awfulness that occurred affects all of the boys not in Jack’s tribe, and in a moment of sheer alarm, Ralph almost snaps: â€Å"That was murder.† Piggy, now the most faithful and loyal friend Ralph has left on the island, can’t bear to even think about it, let alone discuss it: â€Å"You stop it! What good’re you doing walking like that?† By this time, the relationship between Ralph and Jack has deteriorated so much that bitterness from power-possessed Jack is all that is left. By the end of the novel, it is clear that the relationship between Ralph and Jack has no amiability in it whatsoever. The power and authority that Jack enforces over his tribe portrays him as a king to the reader: â€Å"Power lay in the brown swell of his forearms; authority sat on his shoulders and chatted in his ear like an ape.† After Simon’s untimely death, Jack and his tribe seem somewhat unaffected by what they have done, and become even more uncivilised, to the extent that they cause another shocking and unexpected death. Piggy is killed by a rock that Roger pushes over the edge of the cliff, near the beach. This event shows just how disconnected with reality Jack and his tribe have become, and now Ralph is on his own. His only friend’s death has made him now completely alone and so vulnerable. Ralph feels like he is the only one left with any sense of the real world. The shock of what has happened since they first explored the island scares Ralph and fear of the future kicks in. â€Å"These painted savages would go further and further. Then there was that indefinable connection between himself and Jack; who therefore would never let him alone; never.† Jack discovers that Jack and his tribe are planning to kill him the next day, and now survival is the only thing that matters to Ralph. Realisation of his desperate situation comes to Ralph when he is told by one of the twins â€Å"Listen, Ralph. Never mind what’s sense. That’s gone.† A lonely, terrified, weak and exhausted Ralph wakes the next day to noises of every other child on the island hunting him down. They set fire to the island and eventually locate Ralph, and then the chase begins. Ralph reaches the end of island, and the end of his sanity. He literally runs into a naval officer and recognition of everything hits the twelve year old. Shock of the circumstances is all too much for Ralph to bear, and he falls to his knees and breaks down. â€Å"Ralph wept for the end of innocence, the darkness of a man’s heart, and the fall through the air of the true, wise friend called Piggy.† Ralph takes responsibility for the chaos and collapse of civilisation, as he believes that if he had been a better leader, none of this would have happened. He realises just how far things can go when there is no order imposed, and that he alone couldn’t change that. Throughout the novel, Ralph makes a journey towards self-discovery, and witnesses behaviour no other person, like the naval officer, would believe if he explained them. His relationships with the other two main characters influence the horrific events that took place on the island, and at the end of ‘Lord of the Flies’ Ralph sees that man can lose all sense of civilisation when no rules and order are in place.

The evolutionary anatomy

A, Differences between the hip skeleton and muscular structure of two-footed hominid and four-footed apes.TroyWorlds:Reduced tallness, comparative broadness ( it is of import in two-footed position, because the weight of the organic structure does non concentrate onto the spinal cord merely ) . Orientation of blade ( the curvature and the mediolateral orientation of the iliac blades help the Glutei medius and minimi to move as kidnappers and they can besides help in support of the bole. This curving form besides helps in equilibrating the upper organic structure during motive power, because the external and internal oblique musculuss attach to the iliac crest ) . Acetabular border and the well-developed anterior inferior iliac spinal column ( AIIS ) reflects the two-footed motive power. Rectus femoris takes its beginning here, that extends the leg at the articulatio genus. Rectus femur is really of import in some of the spring and clinging prosimians, as the bushbaby and lemurs, because Rectus femur is a leaping musculus in them. However, in apes, there is no big AIIS. AIIS is besides a topographic point for the iliofemoral ligament in worlds that prevents the hip articulation from overstraining. Apes: There is no S-shaped curve visible at the iliac crest and the crest undertakings laterally. Therefore, the iliac pit Easts anteriorly and the gluteal surface undertakings posteriorly. This orientation keeps the bole in an unsloped place during sitting or crouching. In instance if they want to walk bipedally, the Glutei medius and minumi musculuss medially rotate the flexed thigh at the hip – while in worlds they abduct the drawn-out thigh. The long iliac crest is an version to mounting. Latissimus dorsi beginnings from here and inserts into the humerus. Because this is one of the most of import climbing-muscles, the longer the iliac crest is, the better assistance is in mounting. The otic surface and the iliac tubercle are smaller in apes. It is chiefly because of the fact that their weight does non concentrate on their pelvic part and lower limbs ( hind limbs ) .IschiumWorlds:Ischial tubercle is an fond regard for the hamstring musculuss ( Biceps femoris, Semitendinosus, Semimembranosus and Adductor magnus hamstring portion ) . At a superior force per unit area during the two-footed position, the posterior portion of the sacrum elevates, and pulls upwards the ischial tubercle. The ischial tubercle – which is located merely below the great sciatic notch – reflects the bipedalism. Apes: Long ischial bone. The ischial tubercle is wider in apes than it is in worlds and it does non look so â€Å" pulled-up † in apes. The ischial tubercle lacks the aspects for the hamstring and adductor musculuss.PubisWorlds:Pubic crest and pubic tubercle are of import in two-footed motive power every bit good, because the pubic crest serves as an fond regard for Rectus abdominis that supports the backbones and pubic tubercle is associated with the inguinal ligament, which helps in back uping the bole. The iliopubic distinction is the splitter of the Anterior Superior Iliac Spine ( ASIS ) and the AIIS. Here takes topographic point the iliopsoas musculus that helps in flexing the hip and back uping the upper organic structure on the hip articulation. Apes: Apes lack all these human features at the pubic bone: they do non hold a pubic crest nor tubercle, and because their pelvis East otherwise, their ilipsoas channel and iliopubic distinction are losing. The pubic symphysis in apes are normally fuses together, while it merely seldom happens in worlds.AcetabulumWorlds:The orientation of the cotyloid cavity is inferior-lateral-anterior. The superior border of cotyloid cavity must get by with the biggest weight/pressure, it developed a really thick gristle, so did the caput of the thighbone. This is called laubrum. Very strong, Z-shaped, ligaments are present here. The deepness of the cotyloid cavity can state us a batch about the mobility of the hip articulation. If the cotyloid cavity is shallow, it reflects more flexibleness. The cotyloid cavity in worlds is shallow compared to many of the African apes ( but Pan troglodytess ) , but it is deep compared to the orang-utans. Apes: The ligaments are weaker than in worlds.Sacrum, tail boneWorlds:The human sacrum contains five amalgamate vertebrae averagely. However, it can be varied between four and six. The tail bone stands from four amalgamate vertebrae, normally. The sacrum in worlds is wider than in apes and it is non so long as an ape sacrum. This alone form is really typical sing to bipedalism. The wider sacrum means more distance between the sacroiliac articulation, which helps in reassigning the weight and the force per unit area from pubic symphysis. A wider distance at this articulation besides means a larger birth-canal. Apes: In apes and tamper the figure of the amalgamate vertebrae of the sacrum and tail bone may change from species to species. The form of the sacrum is non so broad and more extended. It reveals that they do non back up so immense weight on their pelvic part as do the worlds.FemurWorlds:The human thighbone is longer than that of an ape. The sidelong condyle in worlds is more outstanding. The bicondylar surface is larger in worlds than in apes. It is because of the Centre of gravitation of the organic structure. Apes: Medial condyle is larger in apes. More flexibleness at the hip articulation. B, Actions of musculuss at the articulatio genus and ankle articulations during two-footed motive power. Observed characteristics in hereditary hominid dodos. Extensor muscles of the leg at the articulatio genus articulation:Tensor facia lataeQuadricepss femoris musculuss ( Rectus femoris, Vasti lateralis, medialis, intermedius )Flexor muscles of the leg at the articulatio genus articulation:SartoriusGracilis ( besides can help in median rotary motion )Hamstringing musculuss ( Biceps femoris { it is besides the sidelong rotator of the articulatio genus articulation } , Semimembranosus, Semitendenosus { they besides medially revolve the articulatio genus articulation when the leg is flexed }GastrocnemiusPopliteus ( weak flexor, but it is a median rotator of the leg )PlantarisMuscles that act at the mortise joint ( talotibial ) articulation:Tibialis front tooth ( dorsiflexion )Extensor hallucis longus ( dorsiflexion )Extensor digitorum longus ( dorsiflexion )Peroneus tertius ( dorsiflexion )Peroneus longus and brevis ( plantar flexure )Gastrocnemius ( plantar flexure )Soleus ( plantar flexure )Plantaris ( plantar flexure )Flexor digitorum lo ngus ( plantar flexor )Tibialis buttocks ( plantar flexor )Dodo records: Australopithecus afarensis: The shinbone and the calf bone are rather interesting. We can detect versions to both arboreal and two-footed marks. This is called Mosaic morphology. The examined specimens: AL 129-1b, AL 288-1aq and AL 333x-26 ) . Ape-like elements: short boundary line to the sidelong condyle, in the first two specimens, there are characteristics that general in the apes ( under the epicedial there was the â€Å" hollowed-out visual aspect † ) which means that the Tibialis buttocks attached to the sidelong side of the tibia alternatively of the posterior side. Other fond regards – such as semimembranosus and gracilis are besides instead ape-like. However, other A. afarensis specimens show two-footed features: Distal articulation surface of the shinbone ( the angle of the mortise joint articulation and the shinbone and calf bone ) . But, yet once more, there are ape-like characteristics besides on the distal portion of calf bone: the way of the articular aspect, ( Easts distally instead than medially as in the modern worlds ) , they have an anteriorly oriented peroneal channel on their calf bone while it faces laterally in modern worlds. The A. afarensis Lucy ( AL 288-1 ) besides owns these Mosaic morphological characteristics: the posteriorly oriented distal tibial angle shows similarities with the apes, while in other afarensis specimens the angle is sidelong, which is a human characteristic. The transporting angle at the articulatio genus articulation besides shows more similarities to the modern human specimens. This can uncover an single arboreal wont of Lucy, and a more developed bipedalism in the other specimens. Homosexual habilis: The H. habilis specimens do non do so many statements than the australopithecines. They have more human like characteristics in their lower legs and less ape-like characteristics. Although, they do non miss these characteristics ( rounded anterior boundary line of the shinbone, in worlds the interpolation country of the Flexor digitorum longus is bigger than that of the tibialis posterior – it is rather the antonym in the habilis. The fond regards of other musculuss – soleus, popliteus – show kind of a passage between apes and worlds, etc. ) . The Neandertal mans: The calf bone and the shinbone are really robust, but bear the human features. Q2, Evolution of the early hominid pes The chief features of the human pes include the presence of the arches, the calcaneocuboid articulation, the proportions of the major parts of the pes, the form of the ankle-joint and the fact that the big toe can non be opposed. The arches in pes are rather alone, the apes do non hold arches ( they have merely one arch, the transverse arch ) . In worlds, apart from the plantar aponeurosis, there are other ligaments that aid in holding these arches: the spring ligament, the short plantar ligament and the long plantar ligament. The length of the distal figures of the toes are much shorter in worlds than in apes, nevertheless, the size of the large toe is about the same. The pes of Australopithecus afarensis, such as in the leg, shows Mosaic morphology. It means that certain characteristics are similar to the modern worlds, while others portion similarities with the apes. The human-like morphology: the scree – which besides has both human and ape features – together with the shinbone and calf bone, shows a more human like articulation at the talotibia. Although, the form of the scree is instead ape-like. Other marks that reveal a more human visual aspect in the afarensis pes are the talar trochlear form, the way of the ankle articulation ‘s axis and of the Flexor hallucis longus ‘s channel which suggest that the motions of the afarensis were really similar to those of the modern worlds. The form of the 5th metatarsals reveal a really similar ability of dorsiflexion as it is present in modern worlds. Their scaphoid castanetss in visual aspect are more ape-like, but the presence of the channel of the spring ligament proves that they might hold similar arches than the modern worlds have. The possibility of the two-footed motive power can be traced down besides by the human-like sidelong cuneiform, although, its hook makes it look more ape like. However, the ape-like curves of the phalanges suggest that they might be arborical. The chalky besides have both human and ape like characteristics, the median cuneiform is instead ape like, so is the first metatarsal ‘s rounded caput. The pes of Paranthropus robostus has several human-like features. These characteristics are the undermentioned: the big toe likely was adducted unlike in the apes where the large toe is instead abducted, the plantar ligaments suggest similarities to the human pes, the first metatarsal suggests that it bore more weight than the apes because of its robust visual aspect, but other characteristics on the first metatarsal bone reveal ape-like characteristics, excessively. Harmonizing to the article of Susman and Brain ( 1988, mentioned in Aiello and Dean ) , it is really likely that the Paranthropus robostus was two-footed but in a different manner than the modern worlds. The pes of the Homo habilis: The biggest statement is caused by the tarsal castanetss of a immature Homo habilis ( OH 8 from Olduvai Gorge ) , because some research workers do non believe that the human features of this specimen ‘s pes castanetss are good plenty to be classified as worlds. The elements of the pes show the marks of the bipedalism – even those agree with this who do non believe that this specimen deserves to be included into the Homo genus – but, possibly, in a wholly different manner as it is seen in the modern worlds. Another scree bone, the KNM-ER 813 from Koobi Fora, has less jobs with its categorizations, as it shows more similarities to the scree of the modern worlds. The first metatarsal is the most robust, and the 5th metatarsal bone of the OH 8 is the 2nd, while in apes the 5th metatarsal bone is the weakest. The size of the pes length of the OH 8 is besides more similar to the construction of the human pes. The dodo record suggests that the opposability of the large toe of OH 8 is non present, but the adduction of it can be observed. The ability of grasping is besides really likely, though. The pes of the Neandertal mans: Interestingly, the groundss reveal that the opposability of the large toe might be someplace between the modern worlds and the life apes. Others deny it, because of the more human features in the tarsometatarsal articulation, which can be varied on a great graduated table even in modern worlds. Typical Neanderthal characteristics are the short proximal phalanx of the large toe and the short cervix of the scree. The possible marks of the bipedalism in the fossil groundss: Apart from the castanetss of the pes other skeletal remains can uncover the erected organic structure position and the possible bipedal walking wonts. A comparative longer arm may be a mark of the arborical life-style, or partially arborical life fortunes. However, Lucy has comparatively short fingers, non ape-like, long 1s ( JOHANSON-EDEY 1990 ) The form of shoulder blade and the orientation of the glenoid pit besides can assist to reply this inquiry. A little fragment of an Australopithecus afarensis shoulder blade suggests that its proprietor had a more ape-like in this inquiry, than human like. In apes the glenoid pit faces towards the braincase and this characteristic can be observed besides in instance of this fragment. A more complete shoulder blade – which derives from an A. africanus ( Sts 7 ) – can state us more inside informations about the possible maps of the thoracic girdle. This scapula looks really similar to the scapula fragment of the afarensis specime n ( AL 288-1l ) , and they both bear more similarities to the thoracic girdle of the apes, particularly to the orang-utans. The ribcage has more ape-like features in its visual aspect. The form of the vertebral column, nevertheless, widens distally ( the lumbar vertebrae are the widest ) as it appears in worlds, which is another possible mark of the two-footed motive power. The pelvic girdle shows more groundss for the mosaic morphology yet once more. The iliac crest is instead human-like, although it is more extended laterally and the cotyloid cavity orients more anteriorly. Possibly this is the ground why A. afarensis has a comparatively really long femoral cervix. The iliac blades direct interiorly, as good. The form of the sacrum is really broad – another human-like mark, nevertheless its posterior section is non as curved anteriorly as it is in the modern worlds. Harmonizing to Johanson ( JOHANSON-EDEY 1990 ) , Lucy ‘s pelvic girdle is adapted to the two-footed motive power every bit good as to the possibility to give life to large-headed babes, as her pelvic girdle is so broad. All these characteristics make likely that the A. afarensis could walk bipedally, but in a more complicated manner. The anteriorly faced cotyloid cavity could ensue a really heavy bipedalism. On the femoral caput, we can detect a stronger fovea than it is on the femoral caput of the modern homo. In quadrupeds the tibial tubercle is more rounded and less crisp. The â€Å" acuteness † of the tibial tubercle is a more human ( or bipedal ) feature. This acuteness can be observed in Lucy, although her tibia looks more robust compared to the really tall juvenile, the Turkana male child ( H. erectus ) . In proximal thighbone of the Australopithecines, there are about the same figure of similarities to worlds ( the varied presence of the intertrochanteric line and the Obturator externus channel ) than to Pan troglodytess ( the little femoral caput and the non-flaring greater trochanter ) and the alone characteristics ( long femoral cervix, compressed femoral neck-cross subdivision ) , the more similarities to worlds in the inquiry of the distal thighbone ( the high/very high bicondylar angle, the egg-shaped shaped sidelong epicedial profile ) , and its ain alone phenomena in the epiphysis form and symmetricalness, but the femoral shaft ‘s more similarity to the Pan troglodytess gives us a really eclectic feeling about the possible motive power of the Australopithecines. As I wrote in the 1B inquiry, the pes of the Australopithecines show really varied image every bit good. It reveals both human and ape like characteristics – such as about everything else in the Australopithecus skeleton. The more human like elements of the pes include the human-like mortise joint articulation, the ability of a better dorsiflexion, the expanded base of the 5th metatarsal, the broad heelbone and the presence of the longitudinal arch. On the other manus, there are several ape-like features, like the form of the phalanges, the tubercle of the calcaneous has an egg-shaped orientation, besides has a immense peroneal tubercle, the already mentioned ape-like form of the â€Å" hook † of the sidelong cuneiform bone, and the rounded caput of the first metatarsal. Summarizing, the mosaic morphology in the Australopithecines are really strongly present, they portion similarities to the worlds, every bit good as to the apes, but they besides developed ain characteristics. It is really likely that they were adapted to the two-footed motive power, but non in a modern human manner.
