Aerodynamics Homework - Essay Example ility develops forces that move it further from its position and neutral stability enables the aircraft to maintain the position without moving forward and backward. Control refers to the effectiveness of displacement of regulating features of an aircraft that determines the rate at which the attitudes and direction of flight can be altered. Aircraft control plays a critical role in other features such as stability and maneuvarabilty since it can easily respond to manipulations. Maneuverability is the ability of an aircraft to change direction and attitude as required. Maneuverability is vital in maintaining the stability of an aircraft. This implies that for an aircraft to maintain stability, it must have the tendency of returning to the straight, upright and level attitude (Skiba, 2002). Maintaining a straight level flight and a suitable stability requires aircraft designers build bodies in different levels of static and dynamic stability. The wings of the Spirit of St. Louis were attached above the weight. Charles Lindberg was impressed with the lateral stability of aircraft because the weight that was low above the wing would act as a pendulum to minimise chances of rolling if one if one wing dropped. This type of stability is positive since it was intended to return the aircraft to its original position in case of a disturbance (Skiba,

Problem solving - Essay Example techniques that has been majorly studied, scientifically, involves skin penetration with thin metallic needles which are either manipulated by hands or electricity to bring about pain relief. Acupuncture has been traditionally used in China and other Asian countries; however, it is steadily gaining grounds all over the world in the wake of globalization. NCCAM (2012) confirms this fact by stating that millions of Americans use acupuncture every year to relieve pain. It is evident that acupuncture is being used to relieve pain among patients, but we should ask ourselves whether it is really effective. NCCAM (2012) documents that researchers have studied the effects of acupuncture in managing neck pain, osteoarthritis, shoulder pain, and chronic headache and established that it is an effective pain reliever. This finding defeats the notion that acupuncture is a mere placebo and calls for more clinical referrals and research to improve it. Considering that convectional medicines, p ain killers, have myriad of side effects, some of which may be fatal, it is my opinion that alternative medical practices like acupuncture should be explored and developed to accord medical solutions. Further, research has given robust evidence that acupuncture is useful in pain management, and it is imperative that the same be embraced. However, acupuncturists should take serious precautions to deter its negative effects like allergic reactions and nerve damages. There has to be more research to make acupuncture more effective and to manage its side effects. NCCAM. (2012). Acupuncture; Acupuncture May Be Helpful for Chronic Pain: A Meta-Analysis.

White Supremacy Essay Example for Free

White Supremacy Essay In the aftermath of the election victory of Barack Obama, white supremacists rushed to online discussion forums to vent anger and disbelief that voters had chosen an African-American candidate as the next president of the United States. The Anti-Defamation League, which monitors and exposes extremist activity and rhetoric, said anger among white supremacists and other right-wing extremists in response to Obamas victory, resulted in an avalanche of vitriolic ranting postings on racist Web sites. At one point, the chatter so overloaded the server of the most popular white supremacist internet forum, Stormfront, which was temporarily shutdown. The notion that racism is a violation of human rights is not a new one, as those who have experienced it effects would testify. The ground-breaking progress gained by the civil rights movement of the 1960s in the United States has steadily eroded over the past decade, and the issues and incidents of racism as well as anti-Semitism, homophobia, and violence against women are ones that need to be addressed with increasing urgency. While the courts are more and more frequently relying on civil rights laws to prosecute racially motivated violence, the common abuses of basic human rights are often overlooked. In fact, the encroachment of white supremacist ideologies into the social fabric of our politics, our institutions, and our laws means that intolerance 1. is becoming the rule of the day, and the overt violation of the persons and property of individuals and groups is not only easily accepted, but part of the status quo. America has moved into a new era of white supremacy. The new tactics used by white supremacists and far right organizations must be exposed so that we can work together to mitigate their effectiveness. This includes a discussion of the relationship between three converging and ever-growing factionsthe ultra-conservatives, religious fundamentalists, and the far right. In this context, racism cannot stand alone as the sole antagonist of human rights violations. The victims of white supremacist ideologies and politics include immigrants, gays and lesbians, Jews, and women, as well as people of color. From the ranks of homophobes, anti-abortionists, racists, anti-Semites, and those who are simply afraid of a fast-changing world, white supremacists find willing allies in their struggle to control Americas destiny. Hate groups cannot be dismissed as a more complex than the virulence of a few fringe fanatics. With the breathless way the media covers hate groups, it is sometimes easier to characterize them simply as misfits or extremists, rather than acknowledge them as part of the larger problem of widespread racism, anti-Semitism, and homophobia. FBI statistics report that 65 percent of Americas hate crimes are committed by whites against blacks. A good portion of such hate crimes are what we call move-in violence, when neighborhoods, schools, churches, or jobs are finally integrated 2. 30 years after the 1964 Civil Rights Act. Terror over the visibility of the lesbian and gay movement lays behind the numerous hate crimes against gays and lesbians (and their allies) the fastest-growing hate crime category in the country. Some of the haters, living on the United States borders, are petrified at the thought that brown hordes of Mexicans, Chinese, or Haitians may swarm over them if they cease their militant rhetoric and violence toward these immigrants. If they live near Native American reservations, the aim of their violence is to challenge the few remaining treaty rights granted native peoples. Other white supremacists want to save the white race by controlling the behavior of white womenthey attack interracial couples, lesbians, and feminists. They join the anti-abortion movement, believing they can prevent white women from getting legal abortions. Racist far right organizations have been quick to glorify anti-abortion violence, making it yet another hot issue to fuel the fires of the white revolution. Hate groups have decided that they are no longer willing to wait for the white revolution, the violent backlash against human rights movements. They want a fast solution before, as they put it, the white race is extinct. These fanatics are terrorists who use bombs, murder, arson, and assaults in their genocidal war. Some skinheadsfor example, the Fourth Reich Skins arrested a few years ago in Los Angeles or the Aryan National Front, convicted of murdering homeless people in Alabama are in the vanguard of this street-level violence. Meanwhile, older survivalists like Randy Weaver, who was acquitted of killing a federal marshall in an Idaho firefight in 1992, 3.are barricaded in mountain shelters with stockpiles of weapons, awaiting the final Armageddon. Impressionable, often alienated people, both young and old, are natural recruits for this movement. They bring new energy and a willingness to display their hatred aggressively. They also expand the influence of the white supremacist movement, into the anti-abortion movement, into the anti-gay movement, into the English only movement, opening new avenues for the expression of hate. In the 21st century, the image of organized hate is rapidly changing. It is no longer the exclusive domain of white men over 30. It is becoming younger, meaner and more violent. Many people join the movement as teenagers, including a remarkable number of young women. This new and dangerous increase accounts for nearly one-third of the membership of some hate groups. The increase in the number of women, coupled with a strategic thrust to reform the public image of hate groups, has expanded womens leadership. These new recruits do not fit the stereotypical image of wives on their husbands arms. In fact, many of them are college-educated, very sophisticated, and display skills usually found among the rarest of intellectuals in the movement. Of particular concern in this early 21st century is a continuing convergence of sections of the white supremacist movement with the radical Christian Right, as represented by Pat Robertson, and nationalist ultra-conservatives, as represented by the crackpot Tea Party members and conservative Republicans such as Rick Santorum. This alliance is between religious determinists who think that ones degree of Christianity determines one’s future, economic determinists who see themselves in a 4.war of the haves against the have-nots, and biological determinists for whom race is everything. All believe they are in battle to save Western civilization (white Europeans) from the ungodly and the unfit (people of color, gays and lesbians, and Jews). What many Americans fail to realize is that, increasingly, white people are being literally scared out of their wits by demagogues, who crystallize for them their fears of people of color, lesbians and gays, the government, the media, welfare mothers, immigrants, the economy, health care, and the list goes on. The fact that race relations in the United States are usually presented as a black/white model disguises the complexity of color, the brutality of class, and the importance of religion and sexual identity in the construction and practice of white supremacy. This simplistic model, which fails to convey many of the important aspects of white supremacy, cannot specifically explain how white supremacy influences American culture and politics. White supremacy is an ideology that manipulates US politics and affects all relations in American society. It is sustained by rigid ideological categories. The construction of racial categories, although varying greatly over time, has always been based on the economic, social, and political aspirations of people of European descent. Throughout European history, racial definitions have been based on lineage, characteristics, skin hue, and religion. At the present time, there are not safe places for the victims of this type of violence to turn. No homeless shelters, no womens shelters, and often not even 5. police departments offer them support. The first step in building these resources is to recognize the magnitude of the problem so that human rights activists can come together to offer help and support to those outside the majority rule. A concerted, prolonged effort to teach young people about the true impact of white supremacy and its prevalence in American society is fundamental to breaking the cycle. To ignore this issue is to build intolerance into the next generation. An understanding of the historical and institutional effects of racism and the other isms that dominate our culture and society is vital to understanding present bigotry and abuse. In conclusion, when we recognize that racism, homophobia, sexism, anti-Semitism, and xenophobia flow from the same spring, and that they permeate every aspect of the lives of all Americans, we can then take steps together to make the United States a place that respects and honors the dignity of all people. 6.

The Struggle for Equality: Native-Americans and Asian-Americans

The Struggle for Equality: Native-Americans and Asian-Americans The struggle for equality has been going on since the first European settlers immigrated to the United States. Globalization and Imperialism forced the indigenous peoples of the United States, and also immigrants from other countries, to endure extreme cultural changes. Both the experiences of the Native Americans and the Asian Americans are similar in the attempts by the dominant white culture to affect a total cultural transformation of their way of life. Both groups were considered inferior, dealt with segregation, discrimination, and the rationalization of economic and social exploitations. Native Americans and Asian Americans both suffered restriction of education that was intended to change and control their beliefs and behaviors, in addition to forced internment and relocation. Both groups struggled to preserve their cultures and languages, to be accepted and to receive the liberties that are the right of citizens of the United States. The liberties Americans expect, freedom f rom discrimination, citizenship, the right to sit on a jury, the right to vote, to receive an equal education were for many years denied them. In both cases, fear and greed were the prevailing attitudes that guided those policies of intolerance. From the onset, both the Native Americans and Asian Americans were viewed as inferior to whites and uncivilized. The 1700s classification of Native Americans by Congress as domestic foreigners (Spring, 2010) denied citizenship based upon the Bering Strait Theory that they had crossed over from Asia on the land bridge, and therefore were not white . This was the justification for the classification that all people of Asiatic decent, called collectively by European Americans Mongolians, were not to be considered white and was the basis for the Naturalization Act of 1790 which denied both Native Americans and Asian Americans citizenship. The general view of the Native Americans was a filthy (in the moral sense) savage who not only did not avoid personal pleasure, they enjoyed sex, allowed their women power, were lazy and did not discipline their children. Asian Americans fared no better. Spring (2010) states that in the 1870s in California the Asians were considered an inferior race, barbarians, and any mixing of the races would be the lowest, most vile degraded of our race, and the result of that amalgamation would be a hybrid of the most despicable, a mongrel of the most detestable that has ever afflicted the earth (p. 72) he went on to say that California Representative Romualdo Pacheco maintained, Chinaman [is] a lithe, sinewy creature, with muscles like iron, and almost devoid of nerves and sensibilities. His ancestors have also bequested to him the most hideous immoralities. They are as natural to him as the yellow hue of his skin and are so shocking and horrible that their character cannot even be hinted (p.73). The mind-set of non-European cultures not being white and needing to be civilized, was part of the belief system that the English colonists brought with them that held they were culturally and racially superior. This was used as the validation for taking over the lands of the Native Americans and the forced relocation of the various tribes. Ostensibly, for their own good, the reality was that the land was desired by settlers. This is similar to the Japanese Americans losing their homes and possessions during their internment in concentration camps during World War II. Additionally it was this same not white argument that was used in the 1920s to deny Asian Indians citizenship, and was combined with restrictive court rulings to deny owning land. It was over 160 years after the Naturalization Act that the United States Government acknowledged that naturalized citizenship should not be restricted to whites with the passing of the McCarran-Walter Act in 1952. The political system headed by European-Americans believed that to preserve the survival of the country it was necessary that other groups repudiate their native religions and ways of life, and accept middle class America with its accompanying customs. The hope was to accomplish this by total deculturalization and assimilation through education. It was during the latter part of the nineteenth century that the major policy of the United States Government became one of destroying the customs of the Indians, replacing their languages with English and instilling in them an allegiance to the U.S. Government. The Japanese faced these same tribulations in Hawaii in 1914. Wanting to preserve their culture and language, the local Japanese communities had opened private schools for their children to attend after public school. Spring (2010) explains, they were criticized by local white leaders for hindering the Americanization of Japanese American children and a Territorial Government report f rom that time states, All Americans must be taught to read and write and think in one language; this is a primary condition to the growth which all nations expect of us and which we demand of ourselves (as sited in Hawkins, 1995, p.35). The idea of cultural assimilation combined with the restriction of education was meant to keep other cultures and ethnic groups in line. Both Native Americans and Asian Americans were experiencing segregation or being denied an adequate education. It was not until the civil rights movement that strides were made to redress the deficiencies in schooling, have the schools provide positive images, and reverse the efforts by federal and state governments to destroy the language and cultures of different ethnic groups. The Japanese were, at this time, at a great disadvantage as they were still reeling from the effects of anti-Japanese movies made during World War II and had been villainized by all other cultural groups as a result. The outcome of that polarization of popular opinion was that the Chinese Americans were able to overcome the image of the Chinese opium den deviant which had energized discrimination and segregation. The American Indians wish to be in charge of their own educat ion and re-establish their cultural heritage and languages was made difficult by the attempts in the 1940s and 1950s to end the official status of the tribes. This was not in line with the Indians desires as it would mean dispersal into the general population (Spring, 2010). Banding together into the Pan-Indian movement the tribes in the 1960s led demonstrations to call attention to the plight of the Native Americans and garner political support. At this time, the image of Asian Americans had evolved to the point where they were considered the model minority(Spring, 2010). Regarded by the European Americans as model students who worked hard and got good grades, they were used as poster children to hold up against the African Americans and Hispanics for not working towards the model minority image. Despite strides made by both groups discrimination in education has continued. With a new inflow of immigrants to the United States, multicultural education ranging from bilingual education to instruction in a variety of cultures was proposed. All ethnic groups were expected to benefit from these policies. Unfortunately, the passage of the No Child Left Behind Act which mandated standardized tests to measure achievement, tied to school funding, put an end to that hope. If instructors hoped to ensure the students would be prepared for the high stakes tests that had became mandated than the material needed to be standardized. Sadly, these government created tests create uniformity in knowledge and make a single culture the norm of schooling. (Spring, 2010, p.133)

Computers and Technology :: Technology Essays

Computers and Technology One of the most pivotal technological moments that I can remember from my academic career is the first research project that I had to do early in high school when the internet was considered a valid resource. My school had just established an internet connection, and instead of going to the card catalog in the library, there was a rush for the computers. Encyclopedias and periodical guides had been usurped by this relatively new network of information, and it has changed the way that students do research. Why settle for a couple of magazine articles and a book in a library with limited resources when the World Wide Web offers an almost limitless supply of information on almost every topic known to man? Human beings have been able to perform extensive research on a subject ever since the printed word came into the daily life of scholars, but the advent of the cyberculture era has given us a completely new tool that has both its advantages and disadvantages in the pursuit of knowledge. The one thing that can be said for sure though is that research, whether sparked by casual curiosity or a deadline for a thesis, will never be the same. Until the last decade or so, the bastion of knowledge and information was that building full of books that was known as the library. Print, in the form of books, magazines, newspapers, journals, encyclopedias, atlases, etc., was the primary source for information on virtually any subject. Even dialogue about information was exchanged with printed words on paper or handwritten letters. Then, something strange happened, and all of a sudden, you cannot find a library in a school anymore, there is only the media center. The media center is still a place to gather information, but now computers seem to overshadow the bookshelves. A small school with only a few hundred books is very limited in what topics it can cover, but place one computer in there with an internet connection and it opens a flood of information on everything from socialist realism to belly button lint.

The Neandertals :: essays research papers

The Neandertals Staring into the gloom, I imagine the cave's ancient inhabitants, wrapped in bear skins, huddled near a fire. The haunches of a reindeer roast in the fire. A mother nurses her infant. Children playfully throw pieces of bone into the flames. An old woman tends the wounds of a hunter with an herbal ointment. The strong smells of smoke, unwashed bodies, and rotting carcasses thicken the air.   Ã‚  Ã‚  Ã‚  Ã‚  Until recently, nobody would have assumed that the above passage (Rick Gore, pp.6) was about how the Neandertals lived. However, recent studies have shown that Neandertals are smarter than we first thought.   Ã‚  Ã‚  Ã‚  Ã‚  The geography of the Neandertals domain was quite odd. 230,000 years ago Europe was filled with caves, marshes, and grasslands. It was a very harsh and cold wilderness. The Neandertals were in existence right in the middle of the Ice Age, and although occasional warm periods would create subtropical conditions as far north as England for thousands of years, the glaciers would always return and the Neandertals would always be forced south again. The Neandertals could be found as far north as England and as far south as Spain, from Gibralter to Uzbekistan.   Ã‚  Ã‚  Ã‚  Ã‚  Neandertal bones have been found in the Neander Valley and Dusseldorf Germany, in Altamura, Italy and Vindija, Croatia. These are major sites for the European caves the Neandertals lived in. Although the Neandertals went to the southern tip of Italy, they never crossed the Mediterranean Sea to Africa. They migrated from central Europe to central Asia to the Middle East and always came back. Their main mode of moving around was on their feet, and they usually travelled in bands of no more than 30 people.   Ã‚  Ã‚  Ã‚  Ã‚  The Neandertals had broad noses, and scientists think this was to warm the cold air. They also had thick browridges, receding chins, high foreheads, and their skulls sloped back over their brains. They learned to hunt in groups in order to kill the bigger game. The Neandertals lived with modern humans for 10,000 years, but they didn't change, and eventually it is believed the modern humans conquered them with their more advanced technology.   Ã‚  Ã‚  Ã‚  Ã‚  Although not much is known about the Neandertal's culture, anthropologists have some ideas of how they lived their life.   Ã‚  Ã‚  Ã‚  Ã‚  It is believed by many that the Neandertals practiced cannibalism for a death ritual. There is evidence of this on the skulls and big bones of Neandertals. There are cut marks and some bones have been broken open and are without marrow. Why would they do this? Maybe they liked the way their neighbors tasted, or maybe it was a ritual for a religion of theirs.

How humans activities are altering biogeochemistry and cycling in the water cycles Essay

Men have been involved into different activities that are aimed at the production of important goods and other products for his survival. Through the employment the diverse action towards production of goods and services, there are usually those by-products which perhaps are released as waste to our environment in which we live. Generally, any change in the earth’s chemical composition would have a potential changes in the biota and even the climatic conditions. It is believed that the composition of these wastes that are released to the various environments has fundamental impacts of altering the natural earth chemistry. The alteration of earth’s chemistry affects the cycles of nature like the water cycles which is by itself an integral part of the biogeochemistry. Due to the high impacts which may result from the chemical transition of the earth, it is paramount that the human activities are observed to known the methods in which mankind may contribute to these biogeochemistry changes. . (Hallock and Schlager, 1986) Agricultural sewage Man has always relied on agriculture for his satisfaction of food requirement. The increase in population has led to the intensification and extensive use of land. Due to the overpopulation, invasion of barren lands has been attempted to increase the physical land available for agricultural activities. The practice of the food and animal products in most of these areas call the application of either irrigation techniques or use of soil enriching nutrients. Most of these substances which are used in the soil enrich are fertilizers which are produced from agricultural industries. (Hallock and Schlager, 1986) The agricultural wastes are thus expected to contain traces of worn out particles and ions of iron from the plant manufacture. In addition to the presences of iron, other chemical materials required for the production of chemical fertilizers to some extent finds their way in the sewage wastes. This may includes certain chemical such as magnesium. Iron and magnesium in the earth’s soil may be influenced by the presence of other ions within the water and soils systems. The introduction of these impurities of iron and magnesium to the lakes greatly affects the composition of the chemical ions in the lake water systems. These ions of iron and magnesium react with other abundant ions within the water systems such as sulfate and nitrate forming new compounds altering the chemical compositions (Back, 1979) In the terrestrial land especially in those areas water catchments, sulfates and nitrate ions plays a very important role. They are believed to take part in the control of the level of these iron and magnesium. The excessive released of these iron and magnesium ions from agricultural wastes would usually alter the ability of control of such ions making them to accumulate to higher level where they can be termed as pollutants. The effect of iron and magnesium ions however various as their control level by the nitrate and sulfates ions of and also depend on the level of depth. This means that excessive release of these ions would also affect the nitrates and sulfate ions in the waters systems and soil. (Vollenweider, 1968) Addition of chemical fertilizers Man’s activity of soil enrichment to improve its fertility level is another ways in which the chemical compositions of the earth have been changed. Most of the farming lands have for long time been under cultivation leading to depletion and decrease of plant nutrients. The use chemical fertilizers have always been of prime use to the mitigation of soil fertility for high land productivity. Through the use of these chemical, some have been excessively used such that plant do not utilize them wholly. In most case they remain in the soils were they bind with water available for it to be dissolved. The kind of fertilizers which highly in used is the potassium and sodium nitrates and sulfates which can easily be dissolved. During high rainfalls that lead to flooding or the used of flood irrigation method, these chemical fertilizers are leaked to the water systems at the surrounding places hence there both a changes of the chemical composition in the terrestrial land and in the aquatic systems. (Hallock and Schlager, 1986) The release of these chemical ions to the water sources like lakes is of paramount importance of the aquatics lives. For instances, the enrichment of the water environment with nitrate ions leads to rapid sprouting and development of plant species. This quick growth of the plant displaces the water volume by reaching the maturity and decomposing to contribute to water particulate matter. Through the process of eutrophication, there is increased plant decay thus releasing enormous quantities of carbon dioxide to the atmospheres. (Bormann. and Likens, 1970) Sewage sludge Sewage has several material compositions other than the dissolved chemical substances. Most of the physical materials are eliminated through the sewage treatment processes. However, the separation of the organic and inorganic materials helps men to make manure or fertilizer from the organic portions. Though the materials are treated for safe handling by the human being as fertilizer materials, these manure leads to accumulation of the sewage sludge. The accumulation of the sludge in particular dumping site changes the soils chemical composition. These being mostly organic materials, it means that there high formation of carbon compounds which will be developed in such cite. However, there are other chemical compound which are produced by the natural decomposition especial nitrates and therefore highly in the soil chemical composition. There decomposition of the materials in the sludge releases other chemical such as calcium ions which are convertible to the various carbonates compounds. While the nitrates would enable rapids growth in plants, the presences of calcium ions in the soils accelerates the dissolving of the soil rock. (Bormann. and Likens, 1970) The increase in soil dissolution causes the rates of soils erosions to high. As soils erosion rates increases, there is relative increase in the silting process of the water sources such as rivers and lakes. This decrease the water source depth and therefore reduction of water volumes. The long term effects of the silting process in that elimination of the waters bodies is likely to take place. (Back, 1979) Conclusion Through the use of sewage loading to the lake has high impact to the water source. This is because there is a mass transfer of chemical substances directly and indirectly to the system. The practices of the sewage loading to the lakes has got the potentials of disturbing the water ecosystem through the formation of toxic blooms and the silting of the lake by erosions and decay process of the huge plants materials formed from heavy and rapid supply of necessary products. This shows that environment of the lake is likely to change and be comprising of plants as the major vegetation and living thing. The increase in CO2 gas due to plant decay processes would cause a major change in the environmental temperatures as this is a major green gas pollutant. In addition to increased CO2 gas release; there would be great reduction of the oxygen supply in the lakes due to plant cover over the water surface leading low support of aquatic organisms and animal (Vollenweider, 1968) Reference: Back, W.
