Computer games
2009-12-22
Children nowadays are always very tired after school and they need to relax. The most interesting thing for them to do that is play computer games. Almost every parent worry about how it could affect their children lifes. But I believe that sometimes computer games could even entertain children. First of all, I think that computer game could not only set free from the presure children get at school but also be the best way to educate themselves. If there is special educational game that helps children to have a logical mind finding answers for various situations or helps them with some subjects they cannot understand at school, I think this is very needable and useful. In another hand, usually computer games affect children badly. If there is cruant game, it could get physical result which would be very unpleasant. Also, some children play them all the day and this could became a serious problem. As a result, I would like to say that children really need to relax after a long and hard day at school. But we must be very careful, because spending hours playing computer games might cause problems not only with school work but also with their personal life.

Cheating
2009-12-22
I take a very difficult exam. I have to study for about one week. But I do not. I read a bit every day and I feel calm, because I know I will be able to cheat. Everybody knows that, but some of my group mates study a lot. They study for themselves, for the future or because they are really interested in that subject. I am not interested at all. After the exam we find out that all students got good marks. But somebody is not satisfied or jealous, so he goes and tells the lecturer the names of those people who cheated. He tells my name too. I am very upset- not because I have cheated, but because I can trust nobody in my group. How could I be so stupid and tell that man such a simple thing… Cheating is a very popular phenomenon in our country. In other countries the prevalence of cheating differs. And it is a problem of educational system, not of students. When the disciplines are interesting and useful, students are fond of learning, not of cheating. But the worst thing is that nobody can change this system rapidly: it requires much time, money and hard work. Firstly, honors code like Groveton’s ruins the relationships between students. A student can not trust anybody and tell that he is going to cheat. That is, he has to lie to his mates that he knows a lot, that he has studied for weeks. And it is very difficult (I would say impossible) to find real friends from the university environment. For example, I would not call a friend such a man, to whom I have to lie, who can lodge a complaint against me after every test or exam. The most important thing in friendship is trust and freedom to talk, share impressions. Sometimes it is so great to tell a real friend: “That was the best cheating in my life…” In our society lots of students’ best friends are from their course. If students would have to sign an honor code, the relationships between them changed a lot. There could be no talk about marriages between group mates, because what is a marriage without trust and supporting a spouse? Or there could be another way out of such situation: to break an oath and to lodge complaints only against some students. But on the other hand, if one breaks an oath, there is no need to report about cheating at all. So what should a poor student do? Another difficulty is that the information can be not reliable. If one student hates somebody, it is natural that he tries to do harm to the object of hate. And he can say that he is cheating after every exam and test. Karen Horney says that some people are inclined to competitiveness. Such people try to damage a competitor in order to enhance their own position or glory or to keep down a potential rival. For such a man it is more important to see others defeated than to succeed himself. In universities it is natural that they would try to defeat their mates (competitors) in the easiest way- they will tell that others have cheated. And it is very difficult to check such information. I think that people can not be forced to sign such documents as honor codes, because nobody can make disgraceful people become honorable. The ones who are honorable will not cheat without signing any paper, and the ones who want to cheat, will pay no attention to what they have signed. I think that forcing to sign an honor code would insult me a bit, because I can be honorable without a code, and it is nobody’s business. It is up to me and my conscience to decide whether I will cheat or not. University is not a secondary school, where students have to learn lots of needless subjects. Almost everything that is taught at universities is necessary for the future job. Students choose a profession to study, which interests them, and so they are fond of learning and knowing a lot.
Acid rain
2009-12-22
. On both sides of the border, cars and trucks are the main sources for nitric acid(about 40% of the total), while power generating plants and industrial commercial and residential fuel combustion together contribute most of the rest. In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre©Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic one. This is why many lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced substantially. ACID The average mean of pH rainfall in Ontario's Muskoka©Haliburton lake country ranges between 3.95 and 4.38 about 40 times more acidic than normal rainfall, while storms in Pennsilvania have rainfall pH at 2.8 it almost has the same rating for vinegar. Already 140 Ontario lakes are completely dead or dying. An additional 48 000 are sensitive and vulnerable to acid rain due to the surrounding concentrated acidic soils.Ô ACID RAIN CONSISTS OF....? Canada does not have as many people, power plants or automobiles as the United States, and yet acid rain there has become so severe that Canadian government officials called it the most pressing environmental issue facing the nation. But it is important to bear in mind that acid rain is only one segment, of the widespread pollution of the atmosphere facing the world. Each year the global atmosphere is on the receiving end of 20 billion tons of carbon dioxide, 130 million tons of suffer dioxide, 97 million tons of hydrocarbons, 53 million tons of nitrogen oxides, more than three million tons of arsenic, cadmium, lead, mercury, nickel, zinc and other toxic metals, and a host of synthetic organic compounds ranging from polychlorinated biphenyls(PCBs) to toxaphene and other pesticides, a number of which may be capable of causing cancer, birth defects, or genetic imbalances. COST OF ACID RAIN Interactions of pollutants can cause problems. In addition to contributing to acid rain, nitrogen oxides can react with hydrocarbons to produce ozone, a major air pollutant responsible in the United States for annual losses of $2 billion to 4.5 billion worth of wheat, corn, soyabeans, and peanuts. A wide range of interactions can occur many unknown with toxic metals. In Canada, Ontario alone has lost the fish in an estimated 4000 lakes and provincial authorities calculate that Ontario stands to lose the fish in 48 500 more lakes within the next twenty years if acid rain continues at the present rate.Ontario is not alone, on Nova Scotia's Eastern most shores, almost every river flowing to the Atlantic Ocean is poisoned with acid. Further threatening a $2 million a year fishing industry. Ô Acid rain is killing more than lakes. It can scar the leaves of hardwood forest, wither ferns and lichens, accelerate the death of coniferous needles, sterilize seeds, and weaken the forests to a state that is vulnerable to disease infestation and decay. In the soil the acid neutralizes chemicals vital for growth, strips others from the soil and carries them to the lakes and literally retards the respiration of the soil. The rate of forest growth in the White Mountains of New Hampshire has declined 18% between 1956 and 1965, time of increasingly intense acidic rainfall. Acid rain no longer falls exclusively on the lakes, forest, and thin soils of the Northeast it now covers half the continent. EFFECTS There is evidence that the rain is destroying the productivity of the once rich soils themselves, like an overdose of chemical fertilizer or a gigantic drenching of vinegar. The damage of such overdosing may not be repairable or reversible. On some croplands, tomatoes grow to only half their full weight, and the leaves of radishes wither. Naturally it rains on cities too, eating away stone monuments and concrete structures, and corroding the pipes which channel the water away to the lakes and the cycle is repeated. Paints and automobile paints have its life reduce due to the pollution in the atmosphere speeding up the corrosion process. In some communities the drinking water is laced with toxic metals freed from metal pipes by the acidity. As if urban skies were not already grey enough, typical visibility has declined from 10 to 4 miles, along the Eastern seaboard, as acid rain turns into smogs. Also, now there are indicators that the components of acid rain are a health risk, linked to human respiratory disease. PREVENTION However, the acidification of water supplies could result in increased concentrations of metals in plumbing such as lead, copper and zinc which could result in adverse health effects. After any period of non©use, water taps at summer cottages or ski chalets they should run the taps for at least 60 seconds to flush any excess debris. Ô STATISTICS Although there is very little data, the evidence indicates that in the last twenty to thirty years the acidity of rain has increased in many parts of the United States. Presently, the United States annually discharges more than 26 million tons of suffer dioxide into the atmosphere. Just three states, Ohio, Indiana, and Illinois are responsible for nearly a quarter of this total. Overall, twoªthirds of the suffer dioxide into the atmosphere over the United States comes from coal©fired and oil fired plants. Industrial boilers, smelters, and refineries contribute 26%; commercial institutions and residences 5%; and transportation 3%. The outlook for future emissions of suffer dioxide is not a bright one. Between now and the year 2000, United States utilities are expected to double the amount of coal they burn. The United States currently pumps some 23 million tons of nitrogen oxides into the atmosphere in the course of the year. Transportation sources account for 40%; power plants, 30%; industrial sources, 25%; and commercial institutions and residues, 5%. What makes these figures particularly distributing is that nitrogen oxide emissions have tripled in the last thirty years. FINAL THOUGHTS Acid rain is very real and a very threatening problem. Action by one government is not enough. In order for things to be done we need to find a way to work together on this for at least a reduction in the contaminates contributing to acid rain. Although there are right steps in the right directions but the government should be cracking down on factories not using the best filtering systems when incinerating or if the factory is giving off any other dangerous fumes.
This section describes why leaders exist and what knowledge, skills, and abilities are important to manage learning. We know, to begin, that leaders exist because man is a social creature. The leader in our society is responsible for the essential tasks in the collections of groups that make up civilization. In most traditional or conventional training events, because of a lack of systematic programming, most of the emphasis is focused on attempts to change people's perception. Little time is usually allocated for practice and even less to measure changes in performance during the training situation.

Business Ethics
2009-07-09
Business ethics is a form of applied ethics, a branch of philosophy. As such, it takes the ethical concepts and principles developed at a more theoretical, philsophical level, and applies them to specific business situations. Generally speaking, business ethics is a normative discipline, whereby particular ethical standards are assumed and then applied. It makes specific judgements about what is right or wrong, which is to say, it makes claims about what ought to be done or what ought not to be done. While there are some exceptions, business ethicists are usually less concerned with the foundations of ethics (metaethics), or with justifying the most basic ethical principles, and are more concerned with practical problems and applications, and any specific duties that might apply to business relationships.

For over 60,000 years men and women have been communicating. Yet we still feel the need, perhaps more than ever, to find ways to improve these skills. According to numerous research studies, for your entire life you have spent about 75 per sent of each day engaged in communication. Therefore, you may be wondering why you need to study communication in the first place.
Children start to go school at age of seven. They can stay at secondary school for 12 years but some of them leave it after tenth form. These pupils usually go to vocational junior colleges where they can get secondary education and profession. But these schools are getting less popular now, because more and more students want to study at the University.
