This paper endeavors to analyze how the film Red Cliff displays the Chinese interpretation of various aspects of life, most importantly, the relationship between man and nature, and the relationship between an individual and the state. An Overview of Battle of Red Cliffs The bat tle of red cliffs marked the end of the Han Dynasty. A great warrior known as Cao Cao led his group from the South and fought with his rivals who were led by Liu Cong. As a result, Liu Cong gave up Jing Province (McCurry 5). This was a significant achievement for Cao Cao. After Cao Cao had captured Jing Province, other rivals united to oppose him. Lu Su and Lie Bei combined and formed a strong force that fought Cao Cao’s men at Red Cliffs (Elley 6). The battle between Cao Cao’s warlords and the combined force consisting of Su and Bei’s supporters is known as the battle of red cliffs. The combined force rattled Cao Cao’s men forcing them to retreat. Consequently, Cao Cao conceded defeat. As a result, Cao Cao flew to the North. This boosted the strength of Su and Bei’s territories. Cao Cao decided to consolidate his power in the North. Later, another ruler known as Sun fought Cao Cao and captured Jing Province. After the death of Cao Cao, Lu declared himself as the king of Han Dynasty. However, the remnants of the Han Dynasty engaged in various fights until the dynasty collapsed completely. The collapse of the Dynasty paved way for the emergence of the three kingdoms (McCurry 5). An Overview of the Three Kingdoms The three Kingdoms is a Chinese historical era, which was mainly characterized by disunity. It occurred immediately after the collapse of Han Dynasty. The Han Dynasty is considered as a significant historical event that has shaped Chinese political and cultural aspects. During the Han Dynasty era, China was divided into various regions, which served as administrative posts (Tang 7). In addition, the country had a number of autonomous kingdoms. During the Han Dynasty, China realized economic prosperity. The country was divided into three regional markets. They included the Northwest, the North and the Sichuan. In addition, the routes connecting the three markets were manmade, and they were controlled by the government. The government had immense power and it controlled many affairs. When the Han Dynasty collapsed, the three kingdoms emerged.Advertising Looking for essay on art and design? Let's see if we can help you!

However, during the three kingdoms period, the county realized numerous technological advancements (Elley 8). The three kingdoms finally collapsed following disagreements between leaders of the rival kingdoms. Many individuals who lived during this period have become legends. The film titled Red Cliff mirrors the events of the battle of red cliff. A critical Analysis The first Chinese model explaining the relationship between an individual and the state was documented by Zhang Taiyan (UCP, 2004). Zhang engineered the nationalism concept. Individuals are supposed to put their nati on first (UCP 3). This concept is reflected in the film Red Cliff. In the Film, which is a reflection of the battle of red cliffs, which occurred many centuries ago, each leader puts the country’s interest first. In the film, there are several rival territories each competing for sovereignty as was the case in the battle of red cliffs. For example, the character who mimics Cao Coa aims at solidifying his region’s economic and military prowess. Thus, he fights his rival, Liu Cong in order to capture Jing province. Jing province was an economic and agricultural centre and any leader wanted to control this province. In the film, Red Cliff, the character who is portrayed as Coa Coa shows nationalism by fighting in order to secure a key economic territory for his kingdom. Likewise, the other leaders like Lu Su and Lie Bei fought for the benefit of their territories. At that time, each territory was seen as an independent state, so each leader strived to protect his territor y. The approach used by Lu Su and Lie Bei in which they formed an allied force to oppose Coa Coa’s rivalry, is also highlighted in the film on Red Cliff. This is another sign of the Chinese interpretation of nationalism. The two leaders, Lu Su and Lie Bei, represent true nationalism by joining forces to conquer the enemy. According to Zhan’s interpretation of nationalism, individuals are supposed to cooperate during hard times (UCP 3). In addition, the Chinese interpretation with regard to the relationship between man and nature is best explained ecologically. On top of that, the relationship between man and nature is also linked to the Chinese concept of Confucianism. Thus, the respect for humanity is paramount. Since man relies on nature, Chinese believed that nature has to be guarded against harm. This concept is also portrayed in the film Red Cliff. The rival parties did not interfere with nature. Chinese believe that nature and man are friends and their friendship should not be compromised. Chinese believed that there â€Å"is a need to awe the mandate of heaven and the benevolent regarding anything under heaven and on earth as an integral unity† (Meng 1). Chinese tradition with regard to nature has received global fame. The Chinese culture sees man as an integral part of nature.Advertising We will write a custom essay sample on Chinese Interpretation of Various Aspects of Life through the Film titled Red Cliff specifically for you for only $16.05 $11/page Learn More According to the Chinese tradition, taking life as the essence of benevolence enlivens not only the human consciousness of life, but also an ecology oriented consciousness† (Meng 1). These aspects are portrayed in the film of Red Cliffs. Red Cliff showcases Chinese epic war between rival territories. However, even in the midst of a tough battle, nature is guarded. This is a clear interpretation of the Chinese view with regard to the rel ationship between man and nature. Conclusion This paper has noted that the concepts of the film Red Cliff were borrowed from battle of red cliffs and occurrences, which took place during the final stages of Han Dynasty.

Juvenile Recidivism and Restitution essays

Juvenile Recidivism and Restitution essays Develop a list of reasons why restitution should reduce recidivism and a list of reasons why it might not. Does restitution make sense to you? In the response to the high rise in crime, most states have adopted a "get tough" response to juveniles that focuses solely on punishment. However, many states, strive to maintain a balance between reducing crime and helping young offenders to learn from their mistakes and avoid possible incarceration in the future. A restitution program is a court diversion program that was developed in collaboration with the Juvenile Justice System. The purpose of the program is to provide an alternative to prosecution for first-time juvenile offenders, in certain misdemeanor cases. The focus of the program is to enable youth who have been arrested for committing a crime (e.g. burglary; vandalism; minor assault or other misdemeanors), to meet face to face with the victim and work out a payment plan for the damage suffered by the victim. The program provides all parties in a juvenile offense (the victim, the offending juvenile, and the juvenile's parents or guardians) the opportunity to work out an acceptable plan that directly addresses the harm caused by the criminal act. As a court diversion program, the juvenile restitution program also provides an alternative to criminal prosecution and the exigencies of the criminal justice system. As a diversion program, the offender may avoid criminal prosecution, court appearances, sentencing alternatives and a record of criminal conviction. Likewise, the victim is not subjected to the rigors involved in a legal case, and may have a better opportunity for direct compensation. The victims are often schools, parks, or other government bodies, as well as private shop owners and property owners. The victims and juvenile offenders are often from the same neighborhood or the same general part of the island. Victims and the parents of the juvenile offenders report...

The changing demographics in Texas have transformed electoral politics Essay

The changing demographics in Texas have transformed electoral politics - Essay Example The public policies and traditionally conservative politics of the state, together with the domineering responsibility of a leading structure, are entrenched in these cultural patterns (Zuczek, 2006). This paper will look at how the changing demographics in Texas have transformed electoral politics. Texas has diverse demographics. There has been a significant rise in the general population, with considerable increases among Asian Americans and Hispanics. Hispanics went beyond 35% of the Texas population in 2010. It is also estimated that they will have reach 41% by 2020. In addition, African Americans were approximately 30% of the Texas population during the Civil War, but are now almost 12%. Also, there is a small Native American population made up of three tribes; the Kickapoo, the Tigua, and the Alabama-Coushatta, making up 0.6% of the population. In addition, Asian Americans are approximately 2.7% of the existing population and are anticipated to rise to almost 4.2% by 2020. Angl os make up almost 52.5% of the population and are estimated to decrease as a percentage of the entire population in the next 30 years. In the first quarter of the 20th century, Texas will have a majority minority (Maxwell, Crain & Santos, 2013). The line between San Antonio and Texarkana in effect splits the subcultures of Texas. A large number of Anglos who settled west and north of this line were from the upper South and tremendously influenced by the individualistic subculture, which prefers limited government. Anglos who settled east and south of the line were by large from the lower South and fashioned by its traditionalistic culture (Zuczek, 2006). Politics in Texas is basically fashioned by the racial and ethnic makeup of the population, and, even though the concerns of minorities were historically overlooked, they are now getting increased consideration. This consideration can be accredited in part, to the rising number of minorities elected to local and state offices. Over the last ten years, the population of Texas has risen much quicker than the national average. Between 1990 and 2000, the population of Texas rose by approximately four million people (Maxwell, Crain & Santos, 2013). Movement from other states of the country with stout Republican Party traditions has played a significant part in the transformation of Texas’ conventional one-party Democratic political system into a two-party system. In spite of the sense of wide open spaces and size, Texas is an urban area, with almost 85% of the people living in urban areas. The rise in population presents new requirements on all levels of government, as will the rise in the average age of the population of the state (Maxwell, Crain & Santos, 2013). Almost 10% of the population in Texas was over 65 years old. This number is estimated to rise to 17% by 2030. In addition, significant differences in income levels and wealth exist in the state, leading to political benefits for people who have sig nificant financial resources. Therefore, the economic class has turned into a political subject and income is evidently associated to ethnicity and race, African Americans and Hispanics are more probable to get incomes lower than $15,000. Moreover, there are also significant diffe

Risk Management Essay Example | Topics and Well Written Essays - 4000 words

Risk Management - Essay Example Previously, the safety culture at BP had presented a cause for concern with the Texas City Refinery explosion and other events presenting an adverse image. Toney Hayward, the former CEO of BP, had tried to enhance safety at BP when he took office at a time when BP faced three criminal investigations. However, it would appear that the managerial decision-making processes at BP remained flawed as managers continued to take risks in efforts directed towards trying to manage costs and delays while neglecting safety. Although it is likely that a blowout preventer with a flawed design contributed to the BP Deepwater Horizon disaster, the managerial emphasis on costs and delays caused BP subcontractors to become negligent. BP managers refused Halliburton recommendations to use twenty-one centralisers and proceeded to cement the well using only six centralisers. Halliburton used cement that did not pass its own laboratory tests to cement the well and this contributed to the flow of hydrocarb ons into the well. Transocean crew did not take adequate notice of the kick in the well that pointed to a loss of well control and proceeded to release gases from the well on to the rig through the mud gas separator instead of diverting the gas away from the rig. In addition, inadequate maintenance of the blowout preventer was to contribute to events. Because bonuses presented to BP project managers depended on completing projects close to budgeted costs and schedule, the wrong emphasis had persisted. It is likely that independent verification of managerial decision-making emphasising safety from a command that is distinct from the project management command at BP under a Chief Safety Officer reporting directly to the CEO at BP will help present the correct emphasis. BP did have a safety director at the time of the BP Deepwater Horizon disaster, but it will appear that this safety director lacked powers, a separate chain of command and a capacity for working effectively to give effe ct to his mandate. The new CEO at BP has promised to create a safety division at BP with sweeping powers. BP project managers should now receive bonuses that emphasise correctness of their managerial decision-making for a project instead of receiving rewards for trying to complete a job within budget and schedule while taking risks with safety. In addition, it will make sense for BP to try to contribute towards helping to improve the design and reliability of superior technology for offshore operations, including subsea blowout preventers.

Geology in The United Arab Emirates - Essay Example Over the response of the plate tectonic movement, the two have behaved as a unit. The begun of the separation of this two from African plate started aver about 25- 30 million years ago with the red sea being the initial opening. The U.A.E ancient story was in some points a rumor. A rock, as per the Precambrian history, does not outcrop in the regions of the UAE also; they are not known information drill. In Saudi Arabia and Sultanate of Oman, the exposure of the Precambrian sedimentary rocks were experienced and from this exposure, it participated in delayed Precambrian glaciations. That in many desperate parts of the today’s world were known due the evidence of geology. A shallow red sea covers not much time after the initial appearance of the abundant fossil stable lifestyles during the Middle Cambrian time, a general region that is in the reach of UAE (The Emirates). Thick accumulation of salt and the early Cambrian sediments of both the Arabian sides being included reveal that the area have been the site of first stage drifting from a larger continent that later formed an ocean basin. At the continental edge, the interpretation would account for the UAE subsequent position. The movements of the Afro-Arabian plate in the period of the Paleozoic caused the pass near the South Pole in the Ordovician period. During this period is when North Africa and UAE became glaciated. During the middle of the Paleozoic, the Afro-Arabian continent became the largest in the southern Gondwana supercontinent. The continent later broke into Permian and Triassic. UAE has remained in the tropical latitudes since the end of Paleozoic. The appearance of the UAE has remained tectonically to stable despite the travels. Rather than local tectonic and climatic fluctuations, the geological history of the country as a whole has been based on the primary legend of the advance and retreat of the sea in response to the global idea. The make that was to become of UAE was through the

Junk Food in Schools Essay

Junk Food in Schools Essay Ahmed ALfaraj Schools, it seems, always need more money. One way many of them found funding for things they needed was through corporate sponsorship. While there have been stories about school gymnasiums named after Pepsi, there was a much less noticeable way that corporations sponsored schools and that was through the food that schools provide for the children. The law that says schools must provide children with breakfast and lunches if the kids’ parents cannot afford to pay for them, made it so that schools had to come up with a lot of food for poor kids and that is expensive. Food corporations stepped in and offered their products to schools and schools accepted even if they were not the healthiest of foods. Now, because of things like Pizza Hut pizza, and Smucker’s Uncrustables, without meaning to, schools are contributing to the childhood obesity epidemic by including junk foods in lunches and vending machines. However, thanks to people like Michelle Obama, the unhealthy food h as started to be replaced in many schools through some innovative programs and new government rules about what kind of food can be included in school lunches have helped to keep kids healthy. Most people would agree that offering unhealthy meals to kids at school does not seem like the right thing to do. It is bad enough that many children do not get adequate nutrition at home, but to have the same type of food offered to them at school also seems like a hypocritical thing to do especially when schools are responsible for also teaching healthy life behavior such as eating a healthy diet and getting plenty of exercise. The reason a law was made that required schools to serve healthy lunches and breakfast is that lower-income children may not get enough to eat at home. Not only that with many single-parent households and working families, there may not be anyone to fix meals for children. The law was made so that children would not go hungry. It is a shame that schools then would feed children unhealthy food and allow vending machines that sell junk food. Another reason schools offer meals to children is that children who have eaten breakfast and lunch do much better in school. That has recently been proven by many studies, but that is not the only reason school lunches have been given to children. Nick Confessore of the New York Times says, â€Å"It was the U.S. military that first advanced the national-security implications of a healthful lunch. . . . Gen. Lewis B. Hershey, a former school principal . . . told the lawmakers that as many as 40 percent of rejected draftees had been turned away owing to poor diets† (Confessore). That is how the original National School Lunch program came about. During the 1980s, it was cut along with most other social services by the Reagan administration. Schools began to rely on food from corporations who were competing for the attention of schoolchildren. Of course, there were those federal laws that schools had to comply with, but one way they got around the federal law was to offer unhealth y vending machine products. â€Å"Some districts even struck deals with McDonald’s, Chick-fil-A and other fast-food chains to sell versions of their commercial products directly to school kitchens† (Confessore). That was how Pizza Hut pizza ended up on school lunch trays across the country. Some corporations even drastically reduce the cost of their products for schools. It makes healthy food like fresh fruits and vegetables difficult to serve because they cost so much more than what the corporations provide for free. To compete, the USDA subsidizes school lunch programs. In the Journal of Public Policy Marketing Bree Dority, Mary McGarvey, and Patricia Kennedy explain that the USDA compensates those schools who serve lunches through the National School Lunch Program that meet the 1995 Dietary Guidelines for Americans (205). If a school relies too heavily on corporate sponsorship, they may not get the government money and the breakfast and lunches they serve to children will not be as healthy as those that do receive the government subsidy, but they may actually spend less on food per student. The cost is that those students have a greater risk of becoming overweight or obese and of being not as healthy as children who attend schools where the lunch program is governme nt supported. Most people do not even know that some schools opt for the corporate sponsorship over government sponsorship. Most parents do not look into whether or not their children are served lunches at their school subsidized by government or corporate money. Most probably assume that if there is a free or reduced-cost lunch program that it is through the government. If a person were to ask a group of parents what they thought about the different ways that school lunch programs are funded, those parents would not know that one of the ways is through allowing corporations to provide processed, high in calorie foods for lunches and junk foods in vending machines to schools. Some if not most of those people would say that it is wrong to give children junk food and they would probably find it especially wrong that junk food should be available in schools. Even parents who prepare a lunch at home for their children are having their efforts challenged by the presence of vending machines that offer junk food to children. The presumably healthy food that children bring from home can easily be tossed out and the child can fill up his/her stomach o the empty calorie food found in vending machines. Some people like Phebe Gibson and Lily Swartz are calling for updating the policies concerning junk food at the federal level. Not every school has them because states often oversee school policy and not all states show as great as concern over the health of their children as others. Eliminating junk foods from school cafeterias makes children healthier though. Gibson and Swartz explain that many people all over the country want to remove junk foods from schools. â€Å"A recent poll in California indicates  96% of voters  support serving healthier foods and beverages in schools, and a study conducted at the University of Nebraska-Lincoln found that banning junk food from a la carte lines would result in an18% reductionin overweight or obese students† (Gibson and Swartz). Not only will children be healthier if junk foods are removed from school cafeterias and vending machines, but the childhood obesity problem may be stopped. The argument against the federal government setting guidelines about the types of food that are served in school lunches comes from people who believe the government should not intervene in the lives of people to the extent that they tell them what to eat at school or otherwise. Some say that people should be free to eat what they want even if it is unhealthy. They say that it violates a person’s freedom when the government tells people what they can and cannot eat. Parents should be the ones who decide what their kids eat. Lindsey Tanner of the Huffington Post cites many obesity experts who worry that legislating what people eat may backfire especially where schools are particularly dependent upon food corporation dollars for survival (Tanner). Yet studies show that schools that do ban junk food have fewer overweight and obese students. The same people who want government out of their food are often the ones who say that the presence of junk food in school lunches and vending machines is not the cause of the obesity epidemic. Not every child who eats junk food will become obese. Even those children whose parents are obese may not become obese from eating junk food, even if it is more of a risk for them. The school lunch funding programs that exist help to fund other activities at schools that will help to prevent overweight and obese children such as after-school sports, dance and cheerleading. Linda Gorman also notes that when things like soda are banned, then products like fruit juice, which frequently has just as much sugar as soda, is allowed. Parents and students alike think they are getting healthier foods, but they are not. Gorman says that many feel that banning junk foods will not stop the obesity epidemic (Gorman). For those who believe this, education about the dangers of junk foods is a better policy. Another argument they use is the cost of food. Jan Christensen of CNN says that schools in the more expensive districts such as San Francisco spend, on average, $2.74 per child per lunch. To serve a child a healthy lunch, most experts agree that it costs about $5 per child per lunch (Christensen). Many parents cannot afford to spend that kind of money on their kids’ lunches and many legislators do not want to give that kind of money to schools. Without the corporate sponsorship, it costs too much to provide healthy food in schools. Unfortunately, companies do not give fresh fruits and vegetables to schools. Even if they did, critics of government involvement in school lunch programs point out that the fresh food does not have a long shelf life. Fresh fruits and vegetables become inedible in just a few days. When they go bad, they must be thrown out and that wastes money. The processed food that corporations provide never goes bad, or at least not for a very long time, so there is little waste. Perhaps the real problem is the cost of healthy food and the presence of junk food everywhere in the American culture. Perhaps the regulations should be placed on corporations advertising practices instead of banning them from schools. If kids and their parents saw more promotion of healthier foods, they may be more likely to buy and consume them. Children who eat healthy at home would not develop a taste for empty-calorie food. Then kids would go to school looking for healthy foods and not junk foods and schools would have the opposite problem on their hands: that of turning down sponsorship from companies who want to promote junk foods to children. Either way, school lunches are subsidized by government dollars, and if they are, those dollars should not be adding to the obesity problem that will cost more money down the road to battle. Even if it costs more to put healthy foods in school lunches and in vending machines in schools, it is the right thing to do for the health of child ren. Works Cited Christensen, Jan.

What Affects the Rate of Reaction? :: Reaction Rates Energy Science Essays

What Affects the Rate of Reaction? Hypothesis To form a reaction the particles must collide in high speed. The faster the particles collide the more kinetic energy is produced. This produces a bigger reaction. There are five key variables that affect the rate of a reaction (in this case with a solid and a solution): * Change in temperature An increase in heat energy within the particles leads to more kinetic energy. Therefore there is more collision of particles and it increases the rate of the reaction. When we decrease the amount of heat energy, this will evidently slow down the reaction. For example we slow down the process of our food rotting by placing it in a fridge or a freezer. * Change in concentration The concentrations of acids are classed in molars, so 2m would quite a strong concentrated acid, 0.5m would be a very dilute weak acid and 1m would be in between the two. Also, the more concentrated the acid, the more particles it contains, so there is more of a chance for collisions. * Change of particle size Increasing the surface area of the particles would lead to more collision. We do this by making the particles smaller. For instance peeling a large potato would not take as long as peeling four small potatoes; this is because the smaller potatoes have a larger surface area for you to peel. * Pressure (for gases only) Increasing the pressure would bring particles closer together so there would be more of a chance for collision. * Catalyst A catalyst lowers the activation of energy required, consequently there being a faster reaction. The three variables we are choosing to show which effect the rate of reaction in our experiments are: * Particle size * Concentration * Temperature Pressure was inappropriate to use as a variable, because we were not using two gases and a catalyst was unsuitable to use for small tests like these. I think that the tests in changing the temperature will have the fastest times, as the hotter a solution is the more the particles will move and collide, thus the rate of carbon dioxide being produce will be faster. I also think that the large particles test will take the slowest amount of time because of the lack of surface area and the reverse will occur with the test with powered calcium carbonate. Plan We will be running a various number of experiments to prove what effects the rate of reaction with calcium carbonate (marble chips) and hydrochloric acid. The balanced equation for these reactants along with the products: Calcium carbonate + hydrochloric acid calcium chloride + carbon dioxide + water 2 2 3 2
