marine pollution essays

marine pollution essays The sea is indispensable to life on earth and experiencing serious environmental problems today. Originally nature had the power to clean itself of pollutants to a certain degree. However, the amount of the pollutants discharged by human beings has reached a level which nature cannot cope with. The causes of marine pollution are variety, such as disposal of waste and oil spills, which have caused great and possibly irreversible damage to marine life and could cause extermination of marine life. To prevent the marine environment from further damage, some conventions on the Law of the Sea have been established and implemented effectively. In this paper, the causes and the effects of marine pollution will be firstly identified and discussed. Following this, the law of the sea reviews the overall problems. How to protect marine environment will be finally recommended. Vessel source pollution refers to pollution that comes from ships and has been estimated to comprise up to 40 percent of marine pollution (Kindt, 1986). It may result either because of an accident or because of the natural ways in which ships operate. Accidental vessel source pollution may involve the discharge of dangerous substances, which are transported by sea, including oil, radioactive materials, chemicals and hazardous wastes. Marine accidents potentially cause serious harm to coastal communities, fisheries, wildlife and the local ecology where is a spill takes place. Operational pollution, on the other hand, is caused by the manner in which ships operate. For instance, oil tankers traditionally washed their oil tanks and disposed of oily residues at sea, resulting in significant volumes of pollution. International laws solution to this particular problem has been to eliminate the need for such discharges through technical solutions and the provision of facilities near the sh ore so that these residues can be kept from entering the seas (Timagenis, 1980). ...

HP's strategic choices - Essay Example In the process of discussing the major accomplishments and failures made by Florina, the student will evaluate her decision-makings and the effectiveness of her strategic choices in terms of being able to cut down the operational costs of HP. One of the business strategies that Florina implemented together with the company’s business executives is not to reward employees their annual bonuses in case they fail to meet their profit target each year. (Information Gatekeepers, 2002) Even though holding on employees’ bonuses could save the company a large sum of money at the end of the year, this strategy could de-motivate some of deserving employees within the business organization. Given the fact that some of HP employees were disappointed with the top management’s decision not to release their annual bonuses, the work performance of HP employees may suffer. Back in 2002, Florina was behind the actual merger that has occurred between HP and Compaq Computer. Aside from the fact that merger between the two companies could result to cutting down its operational costs through economies of scale as it increases the market opportunity on the part of HP, some analysts have argued that it was a mistake to pursue the merger between the two companies since this strategy made HP lost some portion of its market shares in some areas. (LaMonica, 2005) Upon analyzing the situation, it is possible for HP to lose some of its market share in certain areas when the top management fails to develop a single organizational goal and business objectives which could align the employees coming from the two separate companies. When there is a miscommunication or internal conflict arising between the two groups of employees, there is a higher possibility for the quality of HP products to decrease due to miscommunication and other technical errors. One of the best ways of maintaining the competitiveness of HP in the global

Drug use and Crime - Essay Example However, had he not been high it is likely the eight young women would not have died. While Speck's case might not be a good indicator of the relationship between drug use and crime, other authorities recognize the relationship. The Drug Enforcement agency has compiled statistics for years concerning the relationship between drug use and crime. A 1997 study of violence against Law Enforcement Officers conducted by the Federal Bureau of Investigation showed that 24 percent of the assailants were under the influence of drugs at the time of the assault and that 72 percent had a history of narcotics violations. (Speaking out Against Drug Legalization, Drug Enforcement Agency fact Sheet 7) Far from being a victimless crime, Drug usage leads to other crime. The United States Postal Service investigated 29 incidents that resulted in 34 deaths in a period spanning thirteen years between 1986 and 1999. Twenty of the thirty-four perpetrators either had a history of substance abuse or were known to be under the influence of alcohol or illicit drugs at the time of the incident. (Speaking out Against Drug Legalization Fact Sheet 7, Drug Enforcement Agency) Unfortunately, Richard Speck isn't an anomaly. Brenda Spencer, a sixteen-year-old high school student went on a shooting rampage January 29, 1979. The troubled teenager was frequently absent from school, was involved in several petty thefts and had a history of drug abuse. She killed two school employees and wounded several students and a police officer in her shooting spree. (World Encyclopedia of 20th Century Murder, Jay Robert Nash, Paragon House Page 533) A 1994 Journal of the American Medical Association article reported that cocaine use was linked to high homicide rates in New York City. The Office of National Drug Control Policy estimated that there were 53,000 drug related deaths in that year. The Vietnam War's death toll was 58,000 for an eight and a half year period.And it isn't just murder. According to the Justice Department's Bureau of Justice Statistics, drug use was linked to crimes against property in 26.9 percent of the reported crimes in 2002. This was an increase of 2.4 percent from just six years earlier. These crimes were committed to get money to buy drugs with. Of all crimes compiled for the report. 16.4 percent were committed to raise money for drugs in 2002, an increase of 1.3 percent from 1996 (Bureau of Justice Statistics, Substance Dependence, Abuse, and Treatment of Jail Inmates, 2002, NJC 209588, July 2005. Approximately two of every five rapes or sexual assault committed against college students, the victims perceived the perpetrator was under the influence of drugs. Of all violent crimes against college students, persons perceived to be under the influence of drugs committed 41 percent. (Bureau of Justice Statistics, Violent Victimization of College Students, 1995- 2000, NJC 196143, December 2003) The statistics become even grimmer when we look at probationers. The first national survey of adults on probation conducted in 1995 found that 14 percent of the probationers were on drugs when they committed their offense. Among those on probation 49 percent of the mentally ill used drugs or alcohol at the time of their offence and 46percent of others used drugs or alcohol at the time. (Bureau of Justice Statistics, Substance Abuse and Treatment of Adults on Probation, 1995, NJC 166611,

Contribution of Functionalism Essay Example for Free

Contribution of Functionalism Essay Functionalists believe that everything in a society contributes to the wellbeing and running of society, e.g. the government, the family, education etc. functionalists are concerned with the role of education within society, Durkheim and Parsons have identified 4 basic functions of education; passing on societies culture – this creates a consensus of shared norms and values. Education also provides a bridge between particularistic values (judging particular individuals values) and ascribed status of the family (fixed by birth) and the universalistic values (judging according to abstract set of standards). Education provides society with a well-trained and qualified workforce. Finally Education selects and allocates people to roles in a meritocratic society and legitimizes social inequality. Functionalists believe that education benefits society as a whole, however Marxists argue that education benefits the ruling class, while feminists see it as benefiting men. The idea that education passes on society’s culture is criticised by Marxists, seeing education as promoting the values of power groups/ruling class. Hargreaves believes that education promotes competition and individualism rather than shared values. If education does provide a bridge between particularistic and universalistic values that education should promote social solidarity – however education can be divisive because the hierarchy of schools and universities can separate class. Education is meant to select the most appropriate people to do particular jobs, however other factors apart from qualifications influence the labour markets (e.g. social contracts), therefore promoting social inequality as a great deal of research shows that class, gender and ethnicity influence achievement, making the labour market unequal. Parsons also argues that schools provide a secondary socialisation. It teaches that relationships in society are based on what people can do for us and what we can do for them; it provides a form of social control and social solidarity, children learn deferred gratification whereby we can’t always g et what we want when we want it. Education also provides a transmission of culture values. Davis and Moore argue education ‘sifts and sorts’ students out – some in different sets and leaving school at different times decides which jobs they end up doing and what class they are in. sifting and sorting can be done through banding and streaming students in to sets, and also through examination. Both Marxists and feminists see that schools play a major role in an excuse of social inequality; the both show an interest in structural relationships of education and different parts of society e.g. the economy. Both prospective see the education system contributing a powerful influence on social solidarity. Marxists believe that the education system serves capitalism and keeps classes divided through banding and streaming. Education serves the needs of society according to functionalists, however Marxists believe that it teachers children to be submissive, through social control and the hidden curriculum. According to functionalists education explains social inequality, whereas it is argued by Marxists that education serves to justify a person’s class position and say that is can be blamed on the individual rather than the unequal structure of society. Marxists view meritocracy as an illusion. Hasley believes that education fails to offer the same opportunity to lower social classes, as to the higher classes. Furthermore Functionalism provides some good points into the ways in which we understand education; however it fails to see the ‘realism’ of meritocracy and social class inequality. Functionalism relies on the assumption that everyone agrees to the norms and values of society, and that the system is meritocratic and equal to all within it.

Economics – What does overall supply of labour depend upon?

1.) What does overall supply of labour depend upon? The overall supply of labour is affected in several different ways. First of all, the working population is considered to be in between 16 and 65 years of age. The inactive population is therefore those younger than 16 and those over 65 years. If there was a huge baby boom in the foreseeable future then the benefits of this would not be felt until some years later when they would become part of the working population. However, in order that the government can gain maximum tax revenue is if more people are in full time education and higher education with the prospect of working in a high paid job. Initially, this would be quite difficult but it would relieve the pressure placed on by the dependency ratio. Other factors that affect the supply of labour are that the death rate is always decreasing therefore the population is increasing. The current health service is going to be put under even more sustained pressure as the more people get older and live longer. This also adds to the increasing dependency ratio. Many people who immigrate to Britain will then, on the whole, add to the overall supply of labour. Another very important factor is that women are getting married later on in life so that they can pursue a career. Also read this  Cheating in a Bottom Line Economy 2.) How do you account for the increase in inactive males in recent years? There are many reasons that men become increasingly inactive in recent years. One reason is, in recent years the primary industry has decreased substantially and the tertiary and services sector has grown considerably. Many men were involved in the primary sector such as factory, coal mining, and farming. Over the last few decades those manufacturing industries have slowly reduced and more tertiary and services have been growing. The tertiary and services sector have a tendency to employ more women, possibly because they are more ‘approachable' than men. One could think of this as sexual discrimination perhaps. Those men who worked in low skilled jobs also found it difficult to adjust to a new job as those low skilled jobs are not readily available. However, the younger male population tend to stay in education additional to compulsory education. 3.) What has been the economic impact of migration both into and out of the British economy over the past 40 years? The impact of migration had many advantages as well as disadvantages. Over the last 40 years migration, in some cases, has severely affected the working population. For example, in the 1960's and 1970's many people chose to migrate to another country so the working population would decrease. The cost of the decrease was a net fall in output. More higher qualified professionals e.g. Doctors, Teachers chose to work away from the UK. This may have a bearing on why there is a shocking lack of teachers around today. Anyway, due to this problem, many people from other parts of the world like Australia, New Zealand, India, South Africa were persuaded to come and work in the UK. 4.) Why are more women becoming more economically active? More women work and have become economically active because of changes in the law forcing firms to have a certain proportion of women in their company. Equal Pay Legislation and Maternity Provision was at the forefront of gaining equal opportunities. Nowadays, many women do not marry when they are in their early 20's but they may do after they turn 30. Theoretically, these women would choose not to have a baby as they would then be tied down and cannot pursue their career. Formerly, women tended to be house wives, they used to all the house work but because of technological advances time taken to do all the housework shortened leaving the women nothing to do for the rest of the day. The other reason is that women are more flexable with their work hours, they tended to work more part-time. The demand for women workers has sharply risen with the increase in tertiary and services sector. More employers are looking for women to improve the appearance of the company. 5.) To what degree has changing the nature of employment within U.K. affected participation ratios of men and women? Over the last few decades, due to the decline in manufacturing industries and the incline of tertiary industries we can conclude that there has been extensive. This is because as manufacturing industries declined many men found it difficult to learn new skills as well as employers preferred to train younger people. The ratio's show this by male inactivity slowly rising as female inactivity fell.

Do All Rivers Flow South

It disturbs me how often Im asked why x river flows northward or for the name of three rivers that flow north. Most of these questions come from Americans who, for some reason, must presume that since the Mississippi flows south, all rivers on the planet flow south. Thus, to hopefully educate the world about the goals and desires of rivers, Ive written a new article called, Rivers Flowing North. Cheers!
