Landmines :: essays research papers

Landmines A recent report on the ban the production and the use of landmines which appeared in the International Post caught my attention. Credit for the lucidly written report should be given to Ms Kazka, a colleague of mine, who illuminated the pertinent issues involved in the controversy revolving the production of landmines. Although the Philippines is fortunate enough not to have experienced the anguish of states like Afghanistan and Bosnia, we as a nation, averse at atrocities brought about by warfare, should contribute to the advancement of this noble cause of banning the production, the use and the demining of landmines. As Ms Kazka reported, each day landmines kill or wound an estimated 75 people worldwide. Ninety percent of these victims are civilians. Among the victims may be a teenage girl gathering firewood in Cambodia. A grandfather herding sheep in Afghanistan. Or a boy running across an empty field in Angola. What makes antipersonnel mines so abhorrent is the indiscriminate destruction they cause. Mines cannot be aimed. They lie dormant until a person or animal triggers their detonating mechanism. Antipersonnel mines cannot distinguish between the footfall of a soldier and that of a child. Those who survive the initial blast usually require amputations, long hospital stays, and extensive rehabilitative services. These people do not usually recover from the psychological strain that the explosions cause. Moreover, they are discriminated by people in their respective society and are considered lower class people. Vivid images of the leg-less people were described in detail by the report In Cambodia alone there are over 35,000 amputees injured by anti-personnel landmines--and they are the survivors. Many others die in the fields from loss of blood or lack of transport to get medical help. Mine deaths and injuries in the past few decades total in the hundreds of thousands. Landmines are now a daily threat in Afghanistan, Angola, Bosnia, Cambodia, Chechnya, Croatia, Iraq, Mozambique, Nicaragua, Somalia, and dozens of other countries. Mines recognize no cease-fire and long after the fighting has stopped they continue to maim or kill. Mines also render large tracts of agricultural land unusable, wreaking environmental and economic devastation. Refugees returning to their war-ravaged countries face this life-threatening obstacle to rebuilding their lives. Leading producers and exporters of antipersonnel mines in the past 25 years include China, Italy, the former Soviet Union, and the United States. More than 50 countries have manufactured as many as 200 million antipersonnel landmines in the last 25 years.

If a question asks you to ‘identify’, ‘ state’ or ‘calculate’ something, you should not write a very long answer. If, however, the question asks you to ‘explain’ or ‘discuss’ something, this will require you to go into much more detail and your answer should be longer. Very often, with a ‘discuss’ question, you will be expected to look at something from two contrasting points of view and then come to a reasoned and well supported conclusion. It is also important that you look closely at the number of marks that are awarded for each part of a question.This will give you guidance as to how long you should spend on each particular part. Some parts of a question will only gain you two or four marks while other questions will have sections worth eight and twelve marks. Remember to look very closely at the precise wording of each part of a question. You need to make absolutely certain that your answer clearly relates to what is specifically required. For example, you ma y answer a question about inflation and write all you know about how it is measured, but the actual question asked required you to write about the difference between two causes of inflation, cost-push and demand-pull.Time management is crucial. Don’t spend too long on one question, or parts of one question, and then leave yourself towards the end of the examination with very little time to read through your answer and correct any mistakes and/or add anything that you feel is missing. W herever possible, use diagrams to aid your explanations, but make sure that they are accurately and clearly drawn and correctly labelled. You should also make sure that you refer to them in your answer. You should also try and bring in appropriate and relevant examples, wherever possible, of current economic issues and problems to support the points you are making.Look back at the question every so often, just to make sure that you are answering the question correctly and staying ‘on trac k’. You do not need to write out the question; this is a waste of your time. Just make sure that you write the number of the question, and the sub-part, so that we know which question you have answered and there is no possibility of confusion as to which question has been answered. Do not answer more questions than you have to. For example in Paper 2, you are required to answer question 1 in Section A and then only one of the three questions in Section B. Cambridge International Examinations 2012 Learner Guide for Cambridge AS and A Level Economics An Example Paper 2 Section A: Question 1 This is the data response question which has to be answered. There are 20 marks available for this question. †¢ †¢ You need to spend time carefully reading through the information provided in Section A. In the example above the data response was concerned with the market for onions in Bangladesh. You need to be confident in what you have read so that you are able to identify, inter pret and manipulate aspects of the data, depending on the particular questions asked.You need to look at the title of the case study; this may well give you some clues as to what you will be required to do in answering the questions.  © Cambridge International Examinations 2012 Learner Guide for Cambridge AS and A Level Economics †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ You need to look at the data provided and appreciate its context. In the example above, this was concerned with the prices of essential foodstuffs in Bangladesh and the implications of this for traders, consumers and the government.If the data is in the form of a table, a chart or a diagram, look for the important features and see if you can identify any patterns, relationships or trends as some of the questions are likely to be drawn from these. Look for the economic theories or concepts around which the case study has been written; think about how and where these theories and concepts are embedded in the data as questions are likely to be drawn from these. In the example above, this was in relation to prices, demand and supply and government intervention in markets). See if there is a stated source for the case study; as this may help you to understand its context.See if you can identify any limitations of the data; for example, there may be other information that you would have found useful, but which has been omitted. The instruction on the examination paper states: â€Å"Brief answers only are required. † You need to be able to quote selectively and answer concisely. You need to look closely at and follow the mark allocation in terms of the time to be taken to answer each part of a question. In the example above, all three parts of (a) were allocated two marks each, both parts of (b) were allocated four marks each, and part (c) was allocated six marks.Half of the time allocated to the whole paper, 1 hour 30 minutes, sh ould be spent on answering Question 1, i. e. 45 minutes. This means that between 13 and 14 minutes should be allocated to each of (a) and (c) and 18 minutes to (b). W here the ‘command’ or ‘directive’ word is calculate, you do not need to go into a great deal of detail. In Question 1 (a) (i), in the example above, you simply needed to calculate the approximate price per kilo of onions in September 2003. W here the ‘command’ or ‘directive’ word is identify, you again do not need to go into a great deal of detail.In Question 1 (a) (ii), in the example above, you simply needed to identify two reasons why prices might normally be expected to rise before the Holy Month of Ramadan; you were not required to explain, analyse or discuss these two reasons. A question will sometimes explicitly require you to include a diagram. This was the case in (b) (i) and (ii), in the example above, when candidates were required to include a demand and su pply diagram. In the case of (i), this was to help explain how traders may benefit from reducing the supply of essential products.In the case of (ii), this was to help analyse the effect on the market for onions of the introduction of an effective maximum price. Your diagrams would need to be neatly and accurately drawn and correctly labelled. You would also need to refer to the diagrams in your answers; that is why it says ‘with the aid of a demand and supply diagram’ in the question. The maximum mark that could have been awarded in each of these sections, if no diagram had been included, was three out of the available four. In some parts of questions, the ‘command’ or ‘directive’ word is explain or analyse.In part (b), (i), in the example above, you were required candidates to ‘explain how traders may benefit from reducing the supply of essential foodstuffs’, while in (ii) candidates were required to ‘analyse the effect on the market for onions of the introduction of an effective maximum price’. It is very important that you fully understand what is meant by these words. Explain means to make clear how or why; analyse means to examine in technical detail. In some parts of questions, the ‘command’ or ‘directive’ word used is discuss.In Question 1 (c), in the example above, the question required candidates to ‘discuss the  © Cambridge International Examinations 2012 Learner Guide for Cambridge AS and A Level Economics †¢ desirability of the Government’s intervention in the market for onions’. You would need to look at this from both points of view, i. e. firstly saying that it would be advantageous and then going on to consider some of the possible disadvantages. You would then be expected to reach a conclusion as to whether it would be particularly desirable for the government to intervene in such a market.The maximum mark for only one side of the argument was four; the maximum mark for both points of view, but without a clear conclusion, was five. You should always try to leave time at the end of answering the question to read through what you have written so that you can check and correct any mistakes and add anything important that you have omitted. Section B: Questions 2, 3 or 4 This is the essay question and you have to answer just one question from this section. There are 20 marks available for this question. †¢ †¢ Each question will be made up of two parts with eight marks for (a) and twelve marks for (b).Part (a) will always require you to explain something. This means that you are required to give clear reasons for something or to make something clear in terms of how and/or why something is happening. For example, in Question 2 (a) you were required to explain how production possibility curves might be used in assessing a country’s economic performance. You would need to demonstrate knowledge of what is meant by a production possibility curve and then go on to explain both the static position of the curve and a movement of it.In Question 3 (a) you were required to explain the difference between absolute and comparative advantage. You would need to define the two terms and then go on to explain the terms and the assumptions which underpin the two concepts. In Question 4 (a) you were required to explain the difference between costpush and demand-pull inflation. You would need to demonstrate knowledge of what is meant by inflation and then go on to explain the two terms and, most importantly, the difference between them.  © Cambridge International Examinations 2012Learner Guide for Cambridge AS and A Level Economics †¢ †¢ †¢ †¢ As has been said, there are eight marks available for part (a), 40% of the total for the question. You should, therefore, aim to spend about 40% of the time available for answering this part of the question. The time allocated to answering this question is 45 minutes, so you need to aim to spend about 40% of that time on part (a), i. e. about 18 minutes. Part (b) will always require you to discuss something. This means that you are required to give the important arguments, for and against, in relation to whatever is being asked.For example, in Question 2 (b) you were required to discuss whether a mixed economy is the best way for a country to deal with the basic economic problem. You would need to demonstrate an understanding of both a mixed economy and the basic economic problem and then go on to discuss both the benefits and the drawbacks of a mixed economy. In Question 3 (b) you were required to discuss whether the principle of comparative advantage is a satisfactory explanation of the trade pattern of an economy with which you are familiar.You would need to apply the principle of comparative advantage to a pattern of trade and discuss the limitations of comparative advantage theory. You would then need t o go on to discuss other explanations of trade. This is a particularly interesting question because instead of requiring you to discuss a particular trade pattern between two economies, you are asked to discuss the trade pattern of an economy with which you are familiar, i. e. you are given the choice of deciding which economy to write about. In Question 4 (b) you were required to discuss whether a country experiencing inflation will always have a balance of payments problem.You would need to explain the link between inflation and the balance of payments and then go on to discuss the conditions when inflation would be likely to bring about a balance of payments problem and the conditions when inflation would not be likely to cause such a problem. As has been said, there are twelve marks available for part (b), 60% of the total for the question. You should, therefore, aim to spend about 60% of the time available for answering this part of the question. The time allocated to answering this question is 45 minutes, so you need to aim to spend about 60% of that time on part (b), i. . about 27 minutes. You should always try to leave time at the end of answering the question to read through what you have written so that you can check and correct any mistakes and add anything important that you have omitted.  © Cambridge International Examinations 2012 Learner Guide for Cambridge AS and A Level Economics Section 3: What will be tested?

Sleep Deprivation And The Use Of Technology - 1222 Words

The objective of this study is to conclude if there is a correlation between ADHD symptoms, depression, sleep deprivation and the use of technology. The participants in this study will be 200 male and female third, fourth and fifth grade students from all socioeconomic levels. These students will be randomly assigned to one of two groups: 1) the majority of classroom assignments completed using technology 2) technology is not used to complete schoolwork. Data will be collected from parents and teachers using three different surveys. They are: the Vanderbilt ADHD Diagnostic Parent Rating Scale and the Centers for Epidemiological Studies Depression Scale (CES-D) as used in the study by Yen et al. (2007) along with a sleep monitoring†¦show more content†¦Restak. An analysis of journal articles concluded several similar research studies in the area of technology and ADHD have been conducted. An evaluation of professional research articles concluded several similar research studies in this area have been completed. One study called Attention deficit hyperactivity symptoms and Internet addiction (Yoo et al 2004) discovered ADHD may lead to internet addiction in elementary students. This same study defines internet addiction â€Å"as pathological Internet use, is conceptualized by an individual’s inability to control his or her use of the Internet, which eventually causes marked distress and/or functional impairment.† (Yoo et al. 2004) This definition is similar to substance abuse characteristics, which include attitude changes and deterioration in the ability to complete tasks. This closely relates to the study being proposed, which suspects student’s using the internet have reduced focus attention difficulty staying se ated and being quiet at expected times, which impacts their ability to finish assignments. Another study considered playing video games with attention issues and impulsiveness (Gentile et al. 2012).
