Research Paper on Water Pollution Research Paper Example

Research Paper on Water Pollution Paper The water pollution can take many forms: chemical, bacteriological, but also a thermal pollution. In addition, it have to be taken into account that polluted water and water bodies may be fresh, brackish, or salt, ground or surface. It may even be rain or dew, snow or polar ice. It can also involve interfaces, including estuaries, wetlands, and particularly its sediments that can absorb and release some pollutants. Sediment can be heavily polluted and retain traces of ancient pollution (there are sometimes a great amount of shot and fishing lead where these activities are practiced). The fight against pollution is very difficult because what is at the bottom of the water, or diluted in water is often invisible, and some toxic infiltrated into the ground often produce their effects after a long time and many pollutants act in complex synergies. In addition, a spill of 4,000 liters of carbon tetrachloride, which occurred near Erstein in 1970, which passed almost unnoticed at the time, twenty years later led to contamination of groundwater and dug a well seven kilometers downstream. Nitrates can achieve some layers after several decades.

In most cases, contamination of water remains invisible because contaminants are dissolved in it. Nevertheless, there are exceptions: foaming cleansers as well as floating oil products and raw sewage. There are also several natural pollutants. Aluminum compounds, which are in the ground, get into water as a result of chemical reactions. The floods washed out of the soil of grassland magnesium compounds, which cause great damage to fish stocks. However, the amount of natural contaminants is negligible compared with human caused pollution. Every year, thousands tons of chemicals with unpredictable effects get in water pools. The water can indicate elevated levels of toxic heavy metals (such as cadmium, mercury, lead, and chromium), pesticides, nitrates, and phosphates, oil, surfactants, and drugs. As you may know, every year up to 12 million tons of oil gets in the oceans. Acid rains make some contribution to the increase in the concentration of heavy metals in water. They are capable of dissolving minerals in the soil, which leads to the increase the content of heavy metal ions in the water. Due to the activity of the nuclear power plants, radioactive waste products get into water.

Free Essays on Historical And Clutural Influences On Twentieth Century Writ

Many different factors affected writing in the twentieth century including two world wars, industrialisation and changes to the social climate. Challenges on ‘The Origins of Species’ by Charles Darwin and the way the human mind works by Sigmund Freud also affected writing. Industrialisation provided large numbers of jobs for the general public. With the increase in employment came an increase in people’s disposable income. As a result of this more people started to enter the education system and standards of education rose. As the country became more literate novels could be written and read by a wider range of people. Up until this time novels had always been written by the upper-middle class who wrote about their experiences. This, therefore, gave novels at the time a very biased viewpoint. Novels in the twentieth century soon began to take on all aspects of life like ‘Saturday Night and Sunday Morning’ by Alan Sillitoe. In this novel Sillitoe looks at the life of a working class man and uses colloquial language and obscenities, which would never have been used in books before this time. The novel ‘Animal Farm’ by George Orwell has been strongly influenced by the Russian revolution so much so that the characters can almost be interchanged with key figures at the time. The two world wars in the first half of the twentieth century had major effects on writing in this period.

Zapatista Social Netwar Research Paper Example | Topics and Well Written Essays - 1250 words

Zapatista Social Netwar - Research Paper Example II. Introduction – background   The insurgency that was initiated in Chiapas, Mexico can be said to different from its old Sandinista-Castroite-Marxist-Leninist rebellion due to the transformation of its engagement from the traditional arm confrontation to the information-technology driven perspective of bringing societal change. It can also be said that this marked the era of post communism revolution that was also used as a revolutionary template in the recent uprisings in the Middle East (Armond, _____). This recent phenomena of using technology, media and NGOs in insurgency can be traced back to the Zapatista National Liberation Army (EZLN) in Mexico in the early 1990s. Chiapas, once an isolated backwater on Mexico’s southern border became the birthplace of the new template in insurgency due to the political and economic factors that made the new type of insurgency ripe. The disparity between the rich and the poor was pervasive which is typical of a feudal state, coupled with the presence of transnational NGOs and discontented indigenas (local indigenous people) who wanted better economic condition and cultural recognition set the stage for the rise of Zapatista National Liberation Army (EZLN). III. ... This proved to be tactically disastrous for EZLN who was less than capable to engage in conflict than the Mexican government. This â€Å"war of the fleas† model of warfare was transformed when the transnational NGOs came and changed the methods of the insurgency from the traditional armed conflict engagement to an informational warfare which is dubbed as Netwar. Should NTS "watch, fear, or be leery" of social movement networks? Its impact on NTS business. Based on the nature, characteristic and manifested action of the players of the insurgency, NTS should be leery of the social movement network. The appropriate behavior would be to be careful but not to be fearful to disengage in business. Being fearful of the social movement network or adopting the plain watch and see attitude will not benefit NTS in the immediate or in the long-term. This assessment is grounded on several reasons. First, the nature, leadership and manifested action of EZLN’s both as an organization a nd a political body is not the Marxist-Lenninist type that disdains business and foreign company. Its leadership was also composed of intellectuals and educated middle class and not the Jihadist type that has penchant to extremism. In short, EZLN’s leadership is reasonable for a business such as NTS to operate and thrive. Second, there is a strong presence of transnational NGOs composed of Mexicans, Americans and Canadian players that provide the Zapatista movement an information age perspective and reassuringly pro-business. Basically, this second component reinforces the political assessment that EZTN is reasonable for it readily shifted its engagement from

Mobile Application for City Target Case Study Example | Topics and Well Written Essays - 750 words

Mobile Application for City Target - Case Study Example E-commerce is an area that has grown tremendously. People can carry out transactions online. Various businesses have gone online for a number of reasons. First and foremost, e-commerce provides one with a platform to reach a larger customer base. A customer can purchase items from a different country from the comfort of their couch. This is made easier by the fact that internet users can access the internet from their mobile phones. For this reason then, it is crucial for businesses to create an online mobile application system that will ensure quality service provision to the customer. City Target is a state street store that deals with a range of products amongst them food, clothes and other household items (ABC, p.1). Through an online business system, the store is set to increase its profit margin. Through the use of a mobile application system, the store stands a better chance of easily reaching more of its customer. Specifically, looking at the professional clothes sale, the st ore can implement several options that can contribute to better service delivery. Online clothes shopping can prove to be challenging since a shopper has to take into considerations many things. Unlike physically shopping for clothes, with online shopping, a customer cannot try out the clothes to see whether they fit well or determine the material’s texture and whether it is to their liking. ... e anytime and anywhere, directly sending advertising and promotional information, better in-store navigation and enhancing customers’ ability to browse order and pay for products using their mobile phones (GS1 MobileCom 9). In shopping for clothes online, web applications have managed to support only basic functions. Some of the problems that a customer experiences include poor fit, mismatch of color and bad drape. This has an adverse effect on the business since the customer will be hesitant to buy a product next time because of dissatisfaction (Beck, p.1). Physically, these problems are catered for through the use of mannequins. Thanks to technological advancement, web applications have been manipulated to counter this problem. These applications cater for garment design, sizing and pattern derivation (Cordier 1). One such application is the 3D graphics technology. This technology offers a range of interactive operations. A shopper is able to adjust a 3D mannequin according to their body’s measurement, select and try different garment items and resize the garment to a mannequin. Furthermore, the application offers real time simulation with respect to garment movement. One store that has successfully used this application is Fits.Me clothes store. Through the store’s virtual room, shoppers are able to create a robotic mannequin with their dimensions and use it to fit clothes (Apparel, p.1). As a result, the company has increased its new customers’ sales by 57% (Fits.Me, p.1). By integrating such an application, City Target is assured of increasing its market base as it offers quality service to its customer. Secondly, City Target could also apply artificial intelligence systems. These systems are created to operate as human intelligence. They are similar to

Political and Economic Causes of the Great Depression

Political and Economic Causes of the Great Depression The Great Depression: Political and Economic Causes in the Americas The Great Depression was a big economic slump in the 1930’s. Many Americans lost their jobs, their savings, and their homes. However, the United States was not the only affected country. The business slump affected the entire world. Many attribute Black Tuesday, when the New York Stock Exchange crashed in 1929, as the major cause, but one can not overlook the fact that there was not just one single factor causing this economic downfall. Most historians and economists agree that the stock market crash was just one of many contributors to the slump. In reality, it was more of a sign that things had already gone wrong. To understand the Depression’s causes, one must go further back. The Great Depression resulted from a combination of economical and political causes that had been building up since months prior to the crash. After World War I ended, American farmers had a difficult time making profits. The farm depression of the 1920’s was a contributing economic factor to the Great Depression. Farmers were producing a surplus and well over what American consumers were purchasing. Prices of agricultural products fell about forty percent by 1921 and remained low for the rest of the decade (Causes of the Great Depression). Some farmers were in so much deficit they couldn’t even pay off the mortgage on their farm and had to rent the land or even leave. Hard times had hit other major parts of the economy, as well, including energy, coal mining, railroads, shipbuilding, and textiles. Businesses had too much inventory and too few buyers. In addition, high tariffs and war debts were political causes of the Great Depression. America had lent money to the United Kingdom and other European nations in World War I reparations. This caused many other economies to become reliant on the U.S. economy. As the United States experienced this economic downturn, many other nations were affected as America insisted on repayment. European countries couldn’t afford to repay their debts. Tensions were further exacerbated when the Hawley-Smoot Tariff Act was passed in 1930. Based on the ideals of protectionism, this act raised import duties to protect American farmers and businessmen, resulting in world trade decline by 66% from 1929 to 1934 and international economic strain (5 Possible Causes of the Great Depression). The 1920’s were a time of great economic and technological growth in America. World War I had just ended, and Americans were ready to take a break from the anxiety of world politics. During this time, known as the Roaring Twenties, Americans were focused on making money and having fun. Factories built to make weapons and ammunition for the war were reestablished to churn out consumer products. But, overproduction in industry resulted in an economic cause of the Great Depression. America was actually more productive than ever, but the gap between the rich and the poor kept growing. Many manufacturers were turning huge profits, but most of that was going to the management, not the workers. Too few workers could afford to buy what the factories were producing. Also, the surplus products could not be sold to foreign countries because of the high tariffs. Still, people rushed to spend their money on cars, radios, telephones and other new technologies.This uneven distribution of inc ome was one of the many economic causes of the Great Depression. â€Å"The top one percent of the wealthy Americans owned over a third of all American assets† (The Great Depression). â€Å"Ninety-nine percent of the population received a nine percent increase in their income, while the top one percent saw their income rise by seventy-five percent† (5 Main Causes of the Great Depression). One of the major infamous events that led to the Great Depression was the Stock Market Crash of 1929. Without the cash to buy of those neat new gadgets like cars and radios, consumers relied on another new invention: credit. Americans were saving less and spending money they didn’t have. They were even borrowing money to invest in the stock market. Stock brokers readily agreed to sell shares on margin, where they would lend citizens money to buy stock. The savings were not insured. Through speculation, these investors figured that the stock prices were bound to go up, allowing them to pay back the stock’s original price ten-fold. This helped inflate stock prices well above what they were actually worth. On October 29, 1929, reality finally caught up to the stock market. Panic spread as the prices dropped. Investors began to sell stock, causing prices to drop. In response, brokers called back their loans. However, investors did not have enough money to payoff the loans. Then, brokers demanded the sale of stocks to payoff the loans. This unending cycle caused alarm and money to vanish. Economies naturally go through periods where there is more supply of products than demand. When that happens on a widespread level, there is a recession, a period where the economy shrinks. There are lots of possible reasons for why the 1929 slowdown turned into a full-fledged depression, which is a longer, more severe recession. When borrowers were unable to repay their loans, banks failed. â€Å"In 1929, there were 25,568 banks in the United States; by 1933, there were only 14,771. Personal and corporate savings dropped from $15.3 billion in 1929 to $2.3 billion in 1933.† (5 Possible Causes of the Great Depression). People everywhere started losing it. They rushed to local banks to withdraw their money while they still could. When that happened, banks across the country went under and had to close– causing thousands of people to lose their life savings. â€Å"As banks went bankrupt, both consumer spending and investment fell into a downward spiral. Output fell while unemployment rose resulting in the negative multiplier effect† (Economics Essays: Causes of Great Depression). Many historians also fault Herbert Hoover, the President in 1929, for making things even worse. He thought the key to ending the panic was balancing the government’s budget, so he raised taxes. That made consumers even less likely to spend, and businesses less likely to risk money on expansion. Finally, a 10-year drought hit the Great Plains in 1930, putting even more pressure on farmers. The Dust Bowl further exacerbated problems caused by the Great Depression. Millions of acres of farmland were rendered useless and infertile. The drought added thousands of farmers to the already growing number of unemployed workers. Reaching its zenith in 1933, unemployment was twenty-five percent (Causes Of The Great Depression | What Happened And How It Compares With Today?). Although some facts are clear-cut, the exact causes of the Great Depression are still being debated. Some of the mainstream theories include the Monetarists view, Austrian view, Keynesian view, and Marxist view. Monetarists believe that the Great Depression was an ordinary recession, but that it degenerated into the Great Depression as a result of the policies implemented by monetary authorities, especially the Federal Reserve. One of the major mistakes was that the Fed did not increase the supply of money to combat deflation. (What Happened During The Great Depression of 1929?). The Austrian view states that the unsustainable credit boom in the 1920’s was the major cause. Particularly, the decision in inflate the U.S. economy to try and help the United Kingdom remain on the Gold standard rate was an indelible mistake (Economics Essays: Causes of Great Depression). They argue that the loss of trust in the banking system was the major harm. The Keynesian theory claims that the problem was the lack of aggregate demand. Based on classical economics, this theory believed that real output would naturally return to equilibrium. However, the Great Depression showed that this was not the case. Keynes argued that governments should intervene in the economy to stimulate demand and fix the problem (Economics Essays: Causes of Great Depression). Lastly, the Marxist View saw the Great Depression as a symbol of the failure of capitalism. Contrary, economies with state-sponsored economic planning, such as the Soviet Union, were more successful as they overcame the Great Depression (Economics Essays: Causes of Great Depression). To this day, economists are still debating the exact causes of the Great Depression. Contrary to popular belief, the Great Depression did not result directly from Stock Market Crash of 1929, but instead from political and economical causes that were building up months prior to the crash. Most historians agree that the Great Depression had devastating effects on the international economy. In order to prevent another catastrophic event from reoccurring, the government generally spends whenever the economy slows. It gives money back to Americans through tax cuts and financial support. Additionally, the Federal Reserve lowers interest rates, making it cheaper for people to borrow money. When people and businesses can borrow money easily, they’re more likely to spend it and keep the economy humming along. This policy has kept recessions from turning into depressions ever since.

Newspaper writer try to explain to the readers what took place and why it is or should be topics of concern police report writing follow the same guidelines. Having the ability to write reports is of extreme importance in police and correctional work daily. Report writing is one of the primary forms of communication within the field of law enforcement agency. Police reports are read by supervisors, police chiefs, fellow officers as well as other criminal justice professionals. Furthermore these documents are written to display the result of an investigation, crimes scene, incidents, and more so it is imperative that there is no grammar errors or misspellings with in the document. Police report writers paint the picture of the events that took place from the time they were called until, the time of their arrival to a crime scene or incident. It’s important that all reports submitted by correctional workers and police officer be well-written with factual information giving step by step details of everything that transpired in chronological order also being very specific about every detail. The reason this is of high important is because this report can assist prosecutor in obtaining a valid conviction of the proper suspect accused (Police reports and there purpose (n.d). Whereas if the police report is poorly written the defense can argue against the finding and may use the discrepancies against the prosecuting state. When poorly written reports are enter into evident for juries to deliberate on it a huge possibility that the report may cause jurors to call into t o question whether the officer who wrote it is as careless in other aspects of their police work. as noted by (Police reports and there purpose (n.d). Another issue that will occur if reports are not properly written is miscommunications or misunderstanding. For example a police officer submits a document with only one misspelled words to his police chief, the chief read the report from the officer he put decrease instead of the deceased and cause the chief to send the report the wrong department.
