Air Pollution - Essay Example This is to the extent its obliteration could extend to affecting our lives in return though in diverse ways including causing cancer. The topic highlights how depositing of varied contaminants in the atmosphere ends up altering the state of air, hence affecting humanity in diverse ways. Depositing in this case not only is it possible through human activities but also natural means like vulcanicity, which based on studies so far conducted these eruptions comprise of HFCs as well as other significant Cl2 quantities. Besides other contaminants, these two agents there severity is worse because they take long before they attain their respective inactivity stages. To date, diverse environmental scholars including scientists through their studies have relayed how varied contaminants by have increasingly yielded to current extent of air pollution. Hence, contributing to worsening of climate change evident in the way varied current incidents are unexpectedly occurring. For instance, rising of sea levels, increased temperatures as well as augmenting prevalence of skin cancer as a result of ozone layer depletion. Recent studies contend early deaths currently experienced globally that approximate to 600,000 their core causes are linked to air pollution (Copenhagen and Haifa, 2015). Hence, prompting states especially in Europe incur economic cost of about $1.6 trillion while trying to manage air pollution related maladies as well as other varied health predicaments (Copenhagen and Haifa, 2015). This is despite states and respective global authorities pushing for the implementation of effective policies known to reduce this kind of pollution. One of this policy of summit whose core intention was to reduce depositing of contaminants in the atmosphere was the today’s famed Kyoto protocol, which some of the super powers declined to append their signatures. Hence, leading to the current increasing rate of air pollution due to competition especially

Development of Chiles Economic Model

Development of Chiles Economic Model William Rodriguez Bibliography B: ‘Formal’ (post-colonial) economic and social development policies, plans, programs and projects, from the dawn of the ‘development era’ up to the present time in Chile. Introduction To obtain a complete perspective and framework of the economic and social development of Chile after the independence to the present time it is essential to see the evolution of the political forces and policies that have shaped the country throughout history. After independence, the institutions and the economy showed no substantial changes for the reason that the revolutionaries were the Landowners, therefore the political power and economy remained oligarchic and centralized. However through time, Chile has had dramatic changes in the social, economic and political structure (Luders, 1993), furthermore sharing similar circumstances with other countries in Latin America such as, social inequality, economic inequality, inflation and dictatorial governments. This bibliography B will analyse the different periods in the history of Chile, going through the changes that the country has experienced since the independence in 1818 to the institutional rupture in 1973 to the transition and consolidation of democracy in 1990. Bibliography PETRAS, J. 1969. Chapter 1: Economic development and Social Change; Chapter 4: The Middle Class; Chapter 6: Christian Democracy; Chapter 9: The Future of Chilean Politics. Politics and social forces in Chilean Development. Berkeley, University of California Press. Petras presents an interesting narrative of all political parties and forces that shaped the development of Chile before the institutional rupture in 1973. In this book, the author argues that the economic and political control was run by the usual elites and middle-class industrialists, however, obvious signs of agricultural and proletarian groups demanding more participation were increasingly visible. According to Petras, Chilean society was a democratic society. However, very few people were involved in the political process because they were controlled by the elite with the socio-economic power, the political parties driving the country according the author were: the Popular Action Front (FRAP) and the Christian Democratic, usually sharing interests and giving no participation to the lowest in the social strata. During the nineteenth century and the twentieth century each president appointed his successor by controlling the ruling classes and elections, political and social reforms were directed by the political class, and society basically was divided into the owners of properties and farmworkers. However according to the author, industrialization has played a role in the development of sectors such as the middle class sectors, strengthening this working class and giving them a more participatory role in Chilean politics and society. The author claims that, the working class must lead the way to change, integrating and becoming a significant force for political and economic development in the country. However, modernization and industrialization created a big difference in the social structure, promoting uneven development between classes during that period. GIL, F., LAGOS ESCOBAR, R. LANDSBERGER, H. 1979. Chapter 1: The Difficult Road to Socialism: the Chilean Case from a Historical Perspective; Chapter 2: The evolution Of the Chilean Political System 1952-1970; chapter 3: The Unidad Popular: A Historical Vision of the Transition to socialism. Chile at the Turning Point, lessons of the socialist years 1970-1973. Philadelphia, institute for the Study of Human Issues. According to the authors, until 1973 Chile had a political stability and the economy before 1952 was characterized by the expansion of the industrial sector. This apparent stability change with the election of Allende in 1970 and what he called the second round to socialism. Allende’s socialist strategies and the actions taken by his government by the nationalization of businesses, industry and banking system, gave way to a political unrest encouraging a system of confrontation; Government run out of options losing control of the country thus facilitating a military coup in 1973. The end of the democracy came with the authoritarian military rule in Chile in 1973, consequently, new policies for inversion, market and international trade, were created. New forms of transforming the economy took place, as well as changes in foreign policy, health services, education, industry and political system. VALDEZ, J. 1995. Chapter 1: Authoritarians without a Project; Chapter 9: In search of Politics; Chapter 10: The elusive Hegemony. Pinochets Economists: The Chicago School of Economics in Chile. Cambridge University Press. The social and political repression of the Pinochet period managed to make possible the implementation of economic changes in 1973, a commitment to free markets and the union of economists with similar ideals enabled the economic growth of the country. The book presents a description of how the government changed the economy of Chile during the Pinochet period, explaining how the group called â€Å"the Chicago boys took control of the economy, initiating economic neo-liberal free trade and radical development strategies to improve the economy. According to the author many of these strategies remained active even after the return to democracy. Valdez (1995), claims that the measures taken by this group of economists represented a record growth in the economy furthermore showing that a highly political environment and ideas provide a solid foundation for the implementation of public policies. BORZUTZKY, S. OPPENHEIM, L. 2006. Chapter 1: The Arduous Road to Democracy; Chapter 2: The consolidation of the Market. After Pinochet: The Chilean Road to Democracy and the Market. University Press of Florida. This book is a collective work of 8 professors, focusing on the period after the Pinochet government and the path to the democracy of Chile, the authors analyse the effect of institutions, market, health care, foreign policy, pensions, and public policies in the Chilean economy and society. Concentrating on the period of 1990-2006 this book is a view on all the factors involved in Chilean society during the twentieth century, including human rights, external politics, openness to market, economic policies, abortion, divorce, political institutions, church and the process of consolidation of democracy through democratically elected governments after the Pinochet regime. Contrary to what other authors argue, Borzutzky (2006) claims that the health policies adopted by Pinochet created a discriminatory system by reducing the budget in the public sector, consequently reducing the quality of the health services. Thea author also argues that the open market philosophy and privatization of the industry constituted a setback for those peasants who legally obtained and worked the land during that period. Discussion â€Å"In the last decades, Chile has suffered drastic changes in its economic, political, and social structure† (Santos, 2005), therefore, to have a detailed understanding and a comprehensive framework of the development of the country it is necessary to analyse the different periods in its history. Petras (1969) and Gil (1979) present a vision of the economy and society before the institutional rupture in 1973, Valdez (1995) poses a vision of the economy and society during the authoritarian military rule, and Borzutzky Oppenheim (2006) focus on the period after the military rule. This diversity of authors presents a complete view of all the elements that have shaped the economy and society in Chile. Petras (1969) and Gil (1979), agree that the economic and political power of Chile before 1973 was in the hands of â€Å"elites† and industrial merchants leaving no participation to the working class in politics, however, this centralized power helped maintain the political stability in the nation for many decades. According to the authors, projects and programs during this period were focused on benefiting the elites, but by the time of the 1970’s, development had increased the gap in the social structure producing a marked inequality in social and economic sectors. Democratic recovery, political stability, and economic growth seem to be the keys for the recent development of the nation (Santos, 2005). However, According to Valdez (1995), Borzutzky () Oppenheim (2006), the political repression of the Pinochet period and the implementation of social and economic reforms, created the basis for the development and economic growth of the country. The reforms made à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹in order to obtain equal opportunities for citizens in terms of health, education, macroeconomic policy, openness to market, and mass privatization of enterprises were key achievements for the reactivation of the economy. A large-scale privatization occurred in Chile by 1974, approximately 550 companies were privatized (Luders, 1993). Consequently the private sector became responsible for growth and also was in charge of financing most of the investment in the country. Furthermore, a greater emphasis was placed on improving exports, avoid monopoly, strengthen the industry, and opening the economy to market. Valdez (1995) suggests that the rapid growth in that period, was due measures taken by â€Å"the Chicago boys a group of young economists who implemented neo-liberal economic policies in the country. In conclusion, Chile is today a clear proof of the imposition of the liberal model upon the economic and political (Moulian, 1997), the effectiveness of the Chilean economic model has become internationally recognized, the low rates of inflation, its policy of Foreign Trade, high investment, trade liberalization, search for social equality, competitiveness, success on social programs in health and education, improvement of labour relations, aid to low-income families, economic Growth, and high levels of internal investment have marked Chile as one of the most successful developing countries in the Latin American area (Muà ±oz, 1993).

Was World War I a total war? Essay -- essays research papers fc

Was World War One a total war? Why? Why not? The First World War of 1914-1918, also known as the Great War, was the first total war in history. What began as a European struggle over the balance of power between the triple alliance of France, Britain and Russia on one side and the central powers of Germany and Austria-Hungary on the other, soon became a global conflict that involved the imperial powers of Europe, their colonies and lands such as the Ottoman Empire, Japan and the United States. Although the sheer number of countries involved in the conflict is enough to describe the First World War as a mass war, what makes it total is the fact that it was waged not only against the enemy’s armies, but also against the civilian population. Military attacks, the use of propaganda and the fact that governments had to mobilise every available human and material resource for the conduct of war affected non-combatants and made World War One a war not fought between armies, but entire societies. Civilians became targets of warfare because their efforts were crucial to the outcome of the war. While fifteen million soldiers died , untold millions suffered off the battlefield. One weapon that had a major effect on warfare in 1914-1918 was the submarine. Since all Britain’s supplies were seaborne, enemies such as Germany resorted to starving the population by destroying British supply ships. The British also found it an effective tactic to blockade supplies to Germany, starving the German war economy and population. Air raids were also a reality for citizens and the general populace had to be ready for the enemy to strike at any time. Attacks were not always so random. An Armenian woman tells of her experiences of being taken from her city with her children, knowing that she was going to be killed - â€Å"I was in the last caravan to leave the city; we knew they were leading us to our deaths†¦there was a well wide open where the executioners immediately threw the wo men they were stabbing.† This is an example that shows how women and children suffered in a conflict that many did not understand or want to be a part of. The use of propaganda and the war of words between belligerents played a big part in making the First World War total, as â€Å"the orgy of killing on the battlefield took place against the backdrop of an orgy of loaded words.† The government and press were able... ...d be directly or indirectly involved in the war – if not physically involved in battle, they could be emotionally affected by the use of propaganda or manipulated by misleading information. Finally, the First World War was waged with armaments that require entire economies to produce them. This means that the war was total because non-combatant involvement in the war effort was essential. BIBLIOGRAPHY Bentley, Jerry H. & Ziegler, Herbert F., Traditions & Encounters, (New York, 2003).

Impact on the Small Coralline Cay

Experiment Number: 5 Date: December 8,2011. Aim: To assess and analyze man’s impact on the small coralline cay- Lime cay. Apparatus: boat Introduction: Lime cay is a small coralline cay that is mostly used by humans for their personal entertainment. By visiting this cay, man has had detrimental effects on the environment. In the earlier times, man’s impact was not so prevalent, however, overtime it has increased as agricultural practices and technology has been introduced. The effects can rise from pollution to global deforestation, which results in the death of many organisms.This can lead to species and genetic diversity being lost and also gives rise to extinction of some species. The adverse effects will be discussed later in details. Procedure: A small boat was used to travel to lime cay where the students walked around the small coralline cay and recorded all observations, which indicated man’s impact on this environment. Observation: Pictures showing the s mall coraline cay-Lime cay and evidence of the presence of man’s pollution. Picture showing an example of an organism that lives on the cay that is affected by man’s presence (sea urchin).Table showing the organisms present on the cay and their preys Organisms Being Fed On| Organisms Feeding| Flowers| Snails and Bees| Snails and Fish| Turtle| Leaf litter | Earthworm| Phytoplankton| Zooplankton| Algae| Sea Urchin and Fish| Fungi| Crab and Sand Fly| Wood| Wood Boring Beetle| Tree Bark| Termite| Woodlouse and Bees| Spider| Bird| Pelican| Bees and Earthworm | Bird| Discussion Questions: (a) Create a food web of all the organisms present on the cay. Pelican Stingray Shark LizardBird Turtle Spider Fish Wood boring Earthworm Sea urchin Zooplankton Bees Snails Crab Sandfly Beetle Termite Leaf litter Algae Phytoplankton Flowers Fungi Wood Treebark (b) What is the significance of the cay? The significance of the cay is to: (1) provide a habitat for a variety of organisms that we re present on the cay (2) to aid in breaking heavy wave and tidal action and (3) to serve as a recreational ground for humans. c) What are the ways that man affects this habitat? Man affects this habitat by pollution when it is used for recreation, by deforestation/slash and burn method, by causing eutrophication, overfishing, oil spills and exposing unwanted predators. (d) Do you see any animals or evidence of any animals? What organisms are affected by man’s activities and how? Yes, there were animals seen. The animals seen were crabs (their tracks and their holes were spotted) ground lizards, pelicans, birds, fishes, sea urchins, spiders (spider webs were spotted) snails, stingray and a turtle.Generally speaking, with human activities being practiced on the cay, it resulted in habitat destruction. Changes usually take time for the organisms to adjust. However, when changes occur at a fast pace, there is little or no time for individual species to react and adjust to new ci rcumstances. This created disastrous results, and for this reason, the rapid habitat loss causes species to migrate to other areas to live. On the cay there was a lot of garbage left behind from human activities. These consisted of mainly plastic materials such as cups and bags.Trash like plastic, can cause death to fishes as plastics take a while to biodegrade and therefore remain in the water. Fishes sometimes mistake plastic for food and ingest it, which results in a blockage in their digestive systems killing the fish. Plastic can also get wrapped around their necks and choke them or it could get stuck in their mouths, making it unable for the fish to eat and so it might starve and also die. Another observation made was a traveling cargo ship. This activity released pollutants into the water and also made it prone to oil spills.An oil spill has the most hazardous effect on aquatic and terrestrial life. The oil coats the fish’s outer layer and kills it. Also, oil affects s ea birds as it sticks to their wings rendering them flightless. Oil settles on top of water and so forms a thick layer that is opaque, which prevents sunlight from reaching marine plants, so photosynthesis is obstructed. Oil spills may result in eutrophication, which feeds algae blooms. When algae dies they sink to the bottom where they are decomposed. The decomposition process uses oxygen and deprives the deeper waters of oxygen, which can kill fish and other organisms.Also the necessary nutrients are all at the bottom of the aquatic ecosystem and if they are not brought up closer to the surface, where there is more available light allowing for photosynthesis for aquatic plants, a serious strain is placed on algae populations. Growth of algal blooms disrupts normal functioning of the ecosystem, causing a variety of problems such as a lack of oxygen needed for fish and other organisms to survive. Also it may be noted that by human activities, which cause organisms to migrate, makes them more available to predation.Additionally, it can increase competition for food and space between organisms. Another point that was observed was the presence of fishermen. Overfishing decreases the population of fishes in the area, which disrupts the food chain as terrestrial organisms that feed on aquatic life have less food to eat. Also human activities affect turtle nesting, as the turtle was seen moving outwards from the cay. This suggested that based on the exposure to unwanted predators, turtles might see the cay as unsafe to lay their eggs.There may have also been introduction to pests as a result of the garbage and also pests may come to the cay in boats. Lastly, we can look at the effect of the method slash and burn method. Evidence of the burning of wood was seen which resulted in the various plants and animals that lived there being swept away. This could also have been the area where only one particular species is kept and slashing and burning could result in extinct ion for that species. This also affects organisms that live in the soil, like the bacteria, that would result in their death. e) Is the only impact by those who visit the cay? No, the impact is not only by those who visit the cay, the impact of the habitat destruction is also by pests as stated before like rats who come on the cay and create mass destruction to the organisms living there. (f) As a manager, what would you suggest to minimize man’s impact on this environment? There should be provision of proper disposal facilities, where the site can be kept clean of litter and the waste and contaminants are not runoff into the water.Implementing in-situ conversation and management practices to exclude or eliminate pests, so pesticides are unnecessary and the organisms will be protected is another suggestion for minimizing the impact. With the prevention of pollution, eutrophication will decrease. Plastics can be collected in a container for recycling, so recycling bin can also be put into play. And lastly, rules should be implemented against burning of materials on the cay. Conclusion: Man has significantly impacted lime cay and evidence was there to support this theory, which resulted in many detrimental effects to the organism present on this cay.

Name and briefly describe the three basic processes of respiration. Ans:1. Pulmonary ventilation is the movement of air in and out of the lungs due to contraction and relaxation of muscles that control the size of the thoracic cavity. 2. External respiration is the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. 3. Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissues. Link to: 22. 3 Inhalation and exhalation 58. Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration. Ans:Elastic recoil is the recoil of elastic fibers stretched during inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during normal breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. Surfactant in alveolar fluid decreases surface tension to help prevent collapse.

In chronic emphysema, some alveoli merge together and some are replaced with fibrous connective tissue. In addition, the bronchioles are often inflamed, and expiratory volume is reduced. Using proper respiratory system terminology, explain at least four reasons why affected individuals will have problems with ventilation and external respiration. Ans:Answers could include: reduced compliance (reduces ability to increase thoracic volume); increased airway resistance (decreases tidal volume); decreased diffusion due to increased diffusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients).
