Outline the causes and effects of one movement of labour from one region to another.

Charis Ow Mr Ben Hough Global Interactions - HL extension Economic interactions and flows Outline the causes and effects of one movement of labour from one region to another. Unemployment has been a serious issue occurring in many regions such as South Asia, where population is growing rapidly and its undeveloped economies -further elevating unemployment rates. Over the years, individuals struggle to look for suitable occupations up to the extent of migrating overseas due to many reasons. There are many causes of the movement of labour from one region to another -one of them is the low wages from their origin which pushes them to look for a better one as it does not pay well enough for them to support their families. For example, LEDCs such as India and Bangladesh would opt for a better lifestyle as they commonly perceive that working overseas would help them to live a more improved lifestyle. In addition to that, labour workers might find that there are better paid wages in other regions such as South East Asia and the Americas so that they could support their family -providing better food and necessities. Besides that, rapid economic development in these MEDCs attracts labour workers to migrate overseas as they believe the economy is more stable and there will be fewer fluctuations of inflation rates so that they would have less risky and long-term jobs.

IB BIOLOGY INTERNAL POTATO OSMOSIS

Aim: To investigate the effect of changing solute concentrations on the process of osmosis in potato chip of a given size. Hypothesis: I predict that as the solute concentration increases, the mass of the potato will decrease because due to osmosis, water has the tendency of flowing to an area of low concentration from an area of high concentration, and as the solute concentrations increase, there will be a lower concentration of water in the solution, hence the potato mass will decrease. The independent variable in this experiment will be the solute concentrations. Water and sugar solutes of 0.1, 0.3, 0.6 and 0.8 mols -1 will be used in the experiment The dependent variable in this experiment will be the mass of the potato chips after osmosis compared to before the osmosis. There are several controlled variable worth mentioning. Make sure all potato chips used are of the same length, by measuring each with a ruler. Use only solid, whole potato chips, check the solidity by observing each chip. Measure the quantity of solutes used with a measuring cylinder, and measure at eye level to obtain accurate measurements, use the same amount of solute for all types of concentrations. Control the time period allowed for osmosis, by timing with an electronic timer from the exact moment the chips are placed in the solutes. The cups used for the solutes must be completely dry before

Lettre au directeur. Objet: Objection la dcision de faire des cours soir supplmentaires obligatoires pour des lves de dernire anne.

Julia D. - présidente du comité des élèves dans Lycée General n° III 70 B/2 rue Reya 80-363 Warsovie Tél: +48 554-24-78 Monsieur le Directeur du Lycée General n° III 27, rue du Legionów 81405 Warsovie Warsovie, le 15 janvier 2012 Objet: Objection à la décision de faire des cours soir supplémentairesobligatoires pour des élèves de dernière année. Monsieur le Directeur, Comme la représentante des élèves de III BI il faut que j'exprime notre déception liée à votre décision d'organiser des cours du soir supplémentaires qui seraient obligatoires pour touts les élèves de dernière année. Nous trouvons cela inadmissible et contre les lois d'élève. Tout d'abord, la majorité des élèves de III BI se sentent déjà suffisamment chargés d'exceptionnellement haute nombre des leçons que nous avons chaque semaine. Nous sommes conscients que s'était notre choix d'étudier dans la classe BI mais au début de notre éducation en BI chacun de nous a choisi le nombre défini des sujets et d'heurs qu'il est capable de suivre. Cela est contre les lois d'élève et, en dehors de cela très insensible de votre part, de nous grever plus. En outre, vous êtes conscient qu'une grande partie d'élèves de III BI vivent loin de l'école. Déjà, sans des leçons additionnelles, ils retournent à la maison très tard après-midi. Sitôt ils

The Effect of Temperature on Enzymatic Activity. Aim To investigate enzyme activity of yeast on glucose at different temperatures

Effect of Temperature on enzyme activity Aim To investigate enzyme activity of yeast on glucose at different temperatures Hypothesis As the temperature increases, enzyme activity will also increase. At lower temperatures enzyme activity will be less than when the temperature is higher. Also if temperature is increased too much, enzymatic activity will fall. This is because the molecules in glucose will move faster and the enzymes will be have increased activity because of increased movement. Also since all enzymes have an optimum temperature at which enzymatic activity is the highest, increasing the temperature will move enzyme closer to optimum temperature. But if temperature is increased too much, enzyme will start to denature (loss of three-dimensional structure) and thus the enzymatic activity will fall again Key Variables Independent: Temperature Dependent: Enzymatic activity (number of bubbles) Controlled: Amount of water that the solution is submerged in Time Concentration of glucose Materials • • 100mL beakers x5 (label from A-E) • • 5 cm3 syringes x5 • • 10 cm3 of 10% yeast solution • • 15cm3 of 2% glucose solution • • 1 thermometer • • 2 hotplates • • Stopwatch • • Ice cubes x 6 • • 400mL water • • Observations chart & pen Method . 1.

Portrayal of colonisers and the colonised in Joseph Conrads Heart of Darkness

Portrayal of colonisers and the colonised in Joseph Conrad's Heart of Darkness Joseph Conrad's novella Heart of Darkness was published 1902, after first being a three-part series in magazines. This book is one of the most influential books in world literature, it has made a huge impact on other authors and some of them have even written a whole book about this book. For example the Swedish author Olof Lagercrantz has written a whole book "Färd med Mörkrets Hjärta" (eng: "Walk with Heart of Darkness"), where he analyses Conrad's work. The book has also been made in to a movie (Heart of Darkness), and inspired a making of another film, Apocalypse Now. The book is about colonisation and can be refer to any colonisation at any time. During the entire book Marlowe, the main character, is retelling the story. In short, the book is about how far the human can go for money and power and also how easily a human being can forget what is right and what is wrong when he is put in unfamiliar environment. In the beginning of the book a story is being told about a Danish man who got killed by the natives after he had attacked them. The reason was because of a misunderstanding about some hence. The Danish man is, or rather was, described as " the gentlest, quietest creature that ever walked on two legs". This statement makes it even more clear how much the coloniser was marked by being

To what extent could Keralas approach in controlling population group be applied to other parts of the world such as China, Nigeria or others?

To what extent could Kerala's approach in controlling population group be applied to other parts of the world such as China, Nigeria or others? Family planning refers to attempts to limit family size. Family planning methods include contraceptives such as the pill as well as drastic methods such as forced sterilization, abortion and infanticide. Kerala had spectacular success in limiting fertility without any strong regulation like China or even any financial support, incentives like other parts of India. Improving of the quality of people living in rural areas was considered to be a que of economic development. India was one of the first countries to attempt an aggressive family program as far back as the 1950's, but the results of such a policy have been mixed over the last six decades. While the population growth in India has slowed in certain provinces, it remains largely outpaced by continuing exponential population growth. The success of government-backed promotion of birth control has had limited by a number of factors, but the most important of these has been, according to the World Health Organization, which is largely supportive of family-planning programs: high level of illiteracy, poor access to information, poverty, and gender-based disparities serve as significant barriers to family planning. These include social stereotypes, lack of male involvement in family

Investigating the factors related to the crater formed by a falling object.

IB Physics SL 2 Leo Tran /17/12 W2 Mr. Chorman Design Lab Investigating the factors related to the crater formed by a falling object. Research The aim of the experiment is to investigate the relationship between the height from which a ball is being dropped on sand and the diameter of the crater it formed from its impact on the sand. This will be done by dropping the ball from fixed heights and then measuring the diameter of the crater formed for each height using an accurate meter scale. If the drop height of the ball is increased then the diameter of the crater will also increase. As the drop height is increased, the potential energy of the ball will also increase since PE = mass * g * height. As a result, the force of impact of the ball on the surface will increase because all the potential energy will be changed into kinetic energy (velocity) of the ball just before its impact on the sand. This increase in the force of impact will move more sand sideways and downwards resulting in the formation of a bigger bowl shaped crater, hence the increase in diameter. Variables * The independent variable is the drop height of the ball. * The dependent variable is the diameter of the crater formed by the impact of the ball on the sand. * The controlled variables include the same snooker ball, same type of sand, and keeping the sand parallel to the ground level.

Earthquakes: the Same Effects, but Differing Responses

Earthquakes: the Same Effects, but Differing Responses Earthquakes are the result of energy release within the earth's crust, as well as an immense natural hazard greatly affecting people - despite whether it is a more or less economically developed country. However, the way in which responses occur may differ between these regions. Underlying friction is the initial cause of earthquakes. As tectonic plates begin to shift, they are resistant and still held together by friction - whether with another plate, or the mantle. However, the force to shift the plate continues despite the friction against this force, until the force overpowers the friction and the plate moves; causing many impacts. Some include shaking and ground rupture; resulting in more or less damage to infrastructure, landslides and avalanches; which can occur if slopes are produced from the earthquake; and fires, if the earthquake causes damage to electrical power or gas lines. Other impacts include those caused by water - such as a tsunami; if the earthquake has caused sudden or abrupt movement of large masses of water, and floods; which occur from an overflow of water onto land. Lastly, humans can be impacted as earthquakes can cause injury and loss of life. Responses to earthquakes are affected by economic factors and types of technology available. Some immediate responses include rescue and medical teams

Economics Article Commentary. London gets EU reprieve over air pollution. The air pollution is a kind of Negative externalities of consumption.

Internal assessment of Economics London gets EU reprieve over air pollution The article is about the over-emitted of air pollution in London. Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the nature environment or built environment into the atmosphere. The air pollution is a kind of Negative externalities of consumption. These occur when the consumption of a good or service creates external costs. These costs are not taken into account by either consumers or producers, so they are not including in price. The tiny sooty particles in London's air are believed to cause asthma, cardiovascular problems, lung cancer and premature death. The negative externalities of consumption produced here make the marginal social benefits in each case less than the marginal private benefits. The marginal social benefit is equal to the marginal private benefits plus the external benefits. If these goods are being over-consuming, then for some of those goods, the overall cost to society is greater than the benefit received . The graph below shows the effect of a negative externality of consumption. According to the article, people who drive cars enjoy the private benefits of the cars, but this will create external costs for other people. This is commonly referred to

China's One Child Policy

Sasha Zouev Geography 09/11/05 China's One Child Policy China is the 3rd biggest country in the world in terms of land area. However in terms of population, China is by far the leading nation with a population of roughly 1,306,313,000 people (2005 est). Brief History of China's Population 1905 - 1978 China was founded in 1949 at a time when the country had a population of about 540 million. Within three decades the population was above 800 million. This record population boost from the 1950s to the 1970s fashioned a strong population momentum that is motivating China's population expansion in spite of already low levels of fertility. It is hypothesized that China's population will grow to some 1.48 billion. Nonetheless, all of this growth will take place during the next 25 years. In its most recent medium variant projection, the UN Population Division estimates that China's population will rise by 260 million between 1995 and 2025. This certainly causes a major crisis for China's food supply: within only three decades the nation will have to feed an additional 260 million people (equivalent to the total population of the USA). At the bottom of the Chinese population pyramid (see fig. 1) one can again see large associates that were born between 1985 and 1990. They are almost as large as the birth cohorts during the "baby boom" years. However, these large number of
