Chromium Essays - Diabetes, Food Science, , Term Papers
Chromium It was known by the 1950s that chromium was needed in humans to control blood sugar, but it wasn't until the 1970s that chromium's main role in humans was found out. It came accidentally, as a result of a new procedure that had been introduced to nourish hospitalized patients who could not take in food by eating. This method of nourishment was designed to give patients all the things people need to maintain health until they could eat normally and get these nutrients from food. Some of the patients who had been fed intravenously for months developed a high blood sugar level just like diabetics (even though they weren't). Then the doctors had to start insulin therapy to treat this diabetes-like condition and even then the insulin didn't work right! People already knew that Chromium was needed to keep normal blood sugar levels, so when they added the Chromium to the food solutions, there was an immediate improvement! The people didn't need insulin injections, and their blood sugars and other problems went back to normal. After a while doctors everywhere figured out that Chromium was needed in humans and they didn't make the old mistakes anymore. Trivalent chromium works with insulin to move glucose into cells, we don't know how else it works but we think it has to do with the insulin binding to their receptor sites. Chromium and Diabetes Three of the 17 good studies showed that there wasn't any benefit of chromium with diabetics, 14 did show blood glucose improvements in the patients. The results were impressive: blood glucose, insulin levels, and cholesterol all decreased, with the higher dose (but not always). No one knows how tiny amounts of chromium could have such big effects on insulin's actions and no one knows why this is so but they believe that chromium strengthens some things that happen between insulin and the body. In other words, it doesn't work by making the body make more insulin, but instead chromium makes the insulin that is there work better in the peoples cells. For all the Health Nuts! An area of interest lately is the possible effect of chromium on body composition; or, how chromium affects the relative amounts of lean body mass (mainly muscle) compared to the amount of body fat. There have been positive results from studies with four separate animal species, pigs, lambs, rats and chickens. They were given chromium picolinate. In all of these species, there were increases in muscle mass and decreases in fat. And, in the case of pigs, the results have been confirmed by many other studies. Unfortunately, for humans, the evidence was not as clear until just recently. Earlier Studies were not even conducted properly so we could not go by their results. But later studies used a large group of about average people and conducted a controlled experiment. After a while there seemed to benefits to the control group and it showed to be a result of the extra Chromium intake! (I wish this was, totally the case because I myself am kind of a health nut) Humans Daily Intake of Chromium Info from U. S. government shows that most Americans get less chromium a day than the amount recommended by nutrition experts (the RDA Committee recommends 50-200 mcg of chromium/day; the vast majority of Americans get less than 50 mcg/day). Not many foods have a lot of chromium. The best foods are organ meats, mushrooms, wheat germ, broccoli and processed meats. It is thought that Stone Age people ate more chromium than modern people because they might have always eaten organ meats from the animals they hunted. And it is most likely that they lost less chromium in their pee than we do. This is probably because Stone Agers didn't eat nearly as much simple sugars as modern people and simple sugar intake causes chromium to be lost in the urine. Americans consume about 120 pounds of sugar per year from regular eating! Another interesting thing is that in large numbers of people in the U.S.-- chromium levels in our tissues lower over our lifetimes. In fact, the highest chromium levels are found in babies! Conclusion Chromium is an essential trace mineral for humans, as far as we know chromium deficiency might have direct effects on a societies obesity, diabetes, abnormal blood lipids, hypertension, and even coronary artery disease. Even though it is all controversial, many sources show that this information is correct. Other Uses - To harden steel, manufacture stainless steel, form alloys. - Used in plating to form

malcolm x essays
malcolm x essays Malcolm Xs experience without the white people as he was growing up brought him to what he believed of white people in his earlier years. He was able to overcome many traumatic experiences in order to keep on going with his beliefs. His message in his earlier years was somewhat harsh on the white population, but in his later years he was carrying a good message towards them. Malcolm X overcame many tough obstacles in his life to become one of Americas most influential black leader of his time. Malcolm X, or Malcolm Little as he was known in his childhood years, had a very traumatic childhood. Encarta states that since his father was a Baptist at a black church the Ku Klux Klan harassed his family often. This would have been very scary for a child of Malcolms age at the time. This is probably one of the reasons why he had a grudge against whites for the better part of his early years. After Malcolms family broke up he lived with many different foster homes until living with his sister in Boston (Schooling 2). As a kid it would be hard traveling all over the country living with different parents every few months. It takes a really emotionally strong person to put up with this type of change so often. His childhood was pretty rough and one of the ways he delt with it was to resort to Malcolm X got involved with all types of illegal activity with some really dangerous people. He was narcotics, gambling, and pimping. He picked up the name Detroit Red when he was involved with illegal activity in Detroit (Schooling 2). He had nowhere else to go or do but be involved with illegal businesses. He formed his own house robbing gang, and he was caught and sentenced to ten years in prison (Arnold and Gutierrez 15). This was in the long run probably the best thing that happened to Malcolms whole life. Going to prison not only stopped him from doing more ille...

Report Essay Example | Topics and Well Written Essays - 2500 words - 1
Report - Essay Example SWAT and Porter analysis demonstrates that the strategy of development adopted by the company for the next two decades is fully in line with the key strengths, opportunities, and competitive forces the Corporation is likely to face in the future. The Port of Brisbane Corporation is a Government Owned Corporation that manages and controls the operations of the third busiest container port in Australia. First small exports through Brisbane were made during the early years of European settlement, and only in the second half of the 19th century it emerged as the main commercial centre in Australia. During only 35 years from 1850 to 1885 net tonnage through Brisbane grew from 8,128 tons to 690,883 ton. In 1888 the Port started to trade frozen beef adding it to the dominant exports of coal and rural products (POB 2007). World War II became the next major milestone in the Port's development. Disruption of normal maintenance dredging activities made the main channel's depths unsuitable for further exploitation by 1949. Construction of Cairncross Dockyard to meet the demand for ship repair facilities was only the first step in the long series of developments in the Port. As a result, total tonnage through the port reached 2.6 million ton in 1961 (POB 2007). The 1960s were marked by two other developments that had essential impact on further operation of the Port. Firstly, the discovery of the Moonie oil fields led to construction of two large refineries at the mouth of the Brisbane River. Secondly, the growth of containerized exports led to a modification in cargo handling technology: the Brisbane's first container terminal was constructed in the Hamilton Reach of the river in 1969 (POB 2007). The Port of Brisbane Corporation was established as a statutory authority in 1976. In 1994 it was corporatized under the Government Owned Corporation (GOC) Act 1993, and on the 1st of July this year the Port of Brisbane Corporation changed from a statutory to a company GOC, listed with the Australian Securities and Investments Commission. Currently, the PBC is a publicly owned organization that operates on a commercial basis and in a competitive environment and manages Australia's fastest growing container port. The Corporation also leases and manages land for port-related purposes and maintains navigable access to the port for commercial shipping. Currently, the Port of Brisbane is the largest general cargo port in the region of Queensland. Annually, more than 2,600 ships exchange over 26 million tons of cargo over the Port's wharves. The exchange is expected to reach 50 million tons by 2025 (POB 2007). Factors of Success The progress made by the Port of Brisbane over less than a decade is impressive. Rapidly developing infrastructure of the Port provides effective transport networks, logistics options, and ensures convenient location of warehouses and other facilities. Currently, the Port's trade consists of a range of containerized, bulk and break-bulk cargoes: it leads the industry in beef and cotton exports holding approximately 50% of Australia's total market in this section (POB 2007).

How did the protestant Reformation change the relationship between Essay
How did the protestant Reformation change the relationship between England and Spain - Essay Example As Franklin (19-21) points out, the problem of Protestantism was not easily solved anywhere. For instance, in England, it led to a bloody religious war that led to the execution of Queen Mary on the order of her half-sister, Queen Elizabeth. Spain, under King Philip, remained faithful to the catholic faith and as a result, it supported the side of England that was supporting catholic faith. After the defeat of the catholic side by the execution of Queen Mary, political tension between Spain and England started to build and within no time, the two nations were on each otherââ¬â¢s throat. In early 17th century for instance, King Philip of Spain sent an army of professional military men to go and fight for the side of England that was supporting catholic faith. This was however retaliation to the action of England fighting non Protestants in Netherlands, which at the time was a colony of Spain. These religious wars continued for decades before ever reaching an amicable diplomatic sol ution. According to William (205), it was not just political relations between these two countries that were severed, since trade was also very much severed between the two nations. At that time, there was almost no private sector and any private businesses that traded internationally. They were only trading locally, and governments were very much involved in international businesses and there were times when people would entirely depend on the government to import essential things such as food and clothing. In realization of this, King Henry of England tried to build a good relationship with Spain, in order to improve the trade between Spain and England. This was achieved by the use of marriages between the sons of King Henry and a Spanish princess (Brans et al. 452). However, when one of the sons decided to divorce his wife, this created problems because the church (catholic) opposed

Measuresure of Organizational Performance Essay Example | Topics and Well Written Essays - 250 words
Measuresure of Organizational Performance - Essay Example It is thus imperative that measures of organizational performance are incorporate into the hospitalââ¬â¢s objectives to meet this anticipated increase in patients. Therefore, it is important that quality and effectiveness measures be taken into consideration. Ensuring that quality and effectiveness in service delivery is not compromised, will aid in making future projections of the number of inpatient and outpatient expected. This will help in strategic planning to determine the number of service facilities needed to accommodate patients and future anticipated profits. This measures will also aid predict demand and hence level of marketing e.g. advertising required. Therefore, using quality and effectiveness as measures of performance, the management can be able to determine number of staff required. For instance, the physicians working at Twin Rivers Community Hospital will have to be employed full time to attend to patients at the hospital. Either these measures will help management determine level of patient satisfaction and the level of competition from St Francis, which is major rival offering similar services with high performance percentages e.g. in cardiovascular

Impact of Natural Disasters on the Economy of Pakistan
Impact of Natural Disasters on the Economy of Pakistan Natural disasters are an increasingly phenomena that we all evidently observe and identify that may have a direct bang on the interests of an area where it hits and also on explicit domestic meters in such areas. Depending of where we live, hurricanes, earthquakes, floods, droughts, etc, are intimidation to living, belongings, industrious assets, and also can have an impact on societal pointers. The increasing occurrence of natural disasters is extremely interrelated to the increasing susceptibility of homes and communities in emergent nations, as earlier socioeconomic vulnerabilities may aggravate the shock of a natural disaster, making harder the course of revitalization (Vatsa and Krimgold, 2000). Therefore, the impact of such events could consequence in an instant raise in poverty and deficiency (Carter et al, 2007). The literature has been still conflicting to a few amounts. For example Benson and Clay (2003) have discussed that the long-standing shock on development of natural disasters is depressing, at the same time as Skidmore and Toya (2002) explain that such tragedy may upbeat impact development in the long run as there is a decrease to returns on physical assets but a boost in human capital, leading to advanced development. Strobl (2008) for the US coastal areas discover that tornados reduce countys development originally by 0.8 per cent, whereas getting your str ength back after in 0.2 per cent. This writer also figures out for Central America and the Caribbean that the impact from a critical cyclone is a diminution of 0.8 percent of development (Strobl, 2008a). The impact of a natural disaster may also origin discriminations. The poor, who undergo from profits rise and fall, and also have imperfect access to monetary services, in the consequences of a disaster may be extra flat to lessen use and have a declining upset in other domestic indicators as a result. Additionally, there are a many non poor, or close to be, who are not insured in opposition to such threats, and then may plunge into scarcity as result of recapitalizing when dealing with with the upset, depending the shock and probability of diminishing into scarcity of the original stock assets and coping means. Furthermore, susceptibility to natural disasters is a multifaceted issue, as it is strong-minded by the financial structure, the phase of growth, prevailing of communal and fiscal conditions, coping means, risk evaluation, rate of recurrence and concentration of catastrophes, etc. The impact on deprived ones could be losing contact with a few vital services, reversals in accretion of corporeal and human funds, and possibly an augment in child employment and unlawful behavior. Lindell and Prater (2003) summarize the significance of shaping the impact and the pretentious agents in natural disasters. First, that information is helpful for policy makers, as they can be acquainted with the need for peripheral support and which may be more efficient; second, definite sections of affected can be acknowledged, e.g. how low income families are affected; and third, it may be also practical for setting up assistance for natural disasters and the latent results. Overall, growing literature has emerged over the last few years on the macroeconomic and development impacts of natural disasters. Amusingly, there is as up till now no harmony on whether disasters are significant from a macroeconomic point of view, and two situations can be identified. The first believes natural disasters a hinder for economic development and is well symbolized by the following reference: It has been argued that although individuals are risk-averse, governments should take a risk-neutral stance. The reality of developing countries suggests otherwise. Government decisions should be based on the opportunity costs to society of the resources invested in the project and on the loss of economic assets, functions and products. In view of the responsibility vested in the public sector for the administration of scarce resources, and considering issues such as fiscal debt, trade balances, income distribution, and a wide range of other economic and social, and political concerns, governments should not act risk neutral (OAS, 1991). The other position sees disasters as entailing little growth implications and consider disasters and their reduction a problem of, but not for development (e.g. Albala-Bertrand, 1993, 2006; Caselli and Malhotra, 2004). These authors find natural disasters do not negatively affect GDP and if anything, GDP growth is improved (Albala-Bertrand, 1993: 207). This paper can be understood as an attempt at reconciling this body of literature. There are two entry points for the analysis. The first is to look at counterfactual vs. observed GDP, the second entry point is to assess disaster impacts as a function of hazard, exposure of assets (human, produced, intangible), and, importantly vulnerability. Overall, the evidence reveals adverse macroeconomic consequences of disasters on GDP. In a medium-term analysis, natural disasters on average seem to lead to negative effects on GDP. The negative effects may be small, yet they can become more pronounced depending on the size of the shock. We tested a large number of vulnerability predictors and found that higher aid rates as well as higher remittances lessen the adverse macroeconomic consequences, while capital stock loss is the most important predictor for the negative consequences. In July-August 2010, Pakistan experienced the worst floods in its history The floods have affected 84 districts out of a total 121 districts in Pakistan, and more than 20 million people one-tenth of Pakistans population More than 1,700 men, women and children have lost their lives, and at least 1.8 million homes have been damaged or destroyed (UN 2010, p.1). In attacking poverty in developing countries, due considerations need to be paid to the vulnerability of households against natural disasters. Poor households are likely to suffer not only from low income and consumption on average but also from fluctuations of their welfare once such disasters occur. These households are vulnerable to a decline in their welfare level because they have limited ability to cope with shocks and also they are subject to substantial shocks, such as weather variability (Dercon, 2005; Fafchamps, 2003). This concern has led to an emerging literature on vulnerability measures in development economics (Ligon and Schechter, 2003; 2004; Kamanou and Morduch, 2005; Calvo and Dercon, 2005; Kurosaki 2006a). We broadly think people as vulnerable when (i) they cannot mitigate income volatility and (ii) their consumption expenditure is volatile over time (they lack reliable coping mechanisms). Vulnerability is thus a forward-looking concept. As an example of low-income countries subject to substantial vulnerability, this paper examines the case of Pakistan. Pakistan is located in South Asia, where more than 500million people or about 40% were estimated to live below the poverty line at the turn of the century (World Bank, 2001). Economic development in South Asia has been characterized by a moderate success in economic growth with a substantial failure in human development such as basic health, education and gender equality (Dr`eze and Sen, 1995). This characteristic is most apparent in Pakistan (World Bank, 2002). Although the overall economic growth rates were improved during the 2000s, poverty reduction was slower than expected. Using a two period panel dataset spanning three years from the North-West Frontier Province (NWFP), one of the four provinces comprising Pakistan, Kurosaki (2006a) and Kurosaki (2006b) show that rural households were indeed vulnerable to substantial welfare fluctuations. Using a three-year pan el dataset from Pakistans Punjab, Kurosaki (1998) shows that farmers consumption was excessively sensitive to idiosyncratic shocks to their non-farm income. Similar findings have been accumulated for rural India as well (Townsend, 1994; Kurosaki 2001). The paper is organized as follows. Section 2 reviews the literature on the macroeconomic impacts of disasters and locates the proposed analysis within the disaster risk management paradigm. In section 3, we present the data and methodology used for projecting the economic impacts for a medium term horizon (up to 5 years after an event), as well as the regression analysis used for identifying predictor variables explaining potential impacts. Section 4 ends with a discussion of possible implications of our analysis. Literature Review The literature on impacts of natural disasters and economic effects is still inadequate and can be separated generally into three different categories. One part of the literature has focused on how several factors intensify susceptibility to natural events. They have maintained a natural vulnerability framework in view of climate change, deforestation and geophysical factors (McGuire, Mason and Kilburn, 2002), other than rising urbanization which brings ecological risks and exposure to threats from deficiency of sufficient urban development and dual political discourse (Pelling, 2003 and 2003a), or even environmental immediacy to exposure, access to property and public conveniences as well as political and social networks (Bosher, 2007). All these parts become a thread to population, their assets and possessions and their dynamic competence, becoming then an expected risk. And when such danger is realized, then it turns out to be a natural adversity (see McGuire, Mason and Kilburn, 2002). Although this thread of the literature distinguishes that such risk factors influence the impact of the natural tragedy, they just briefly point out essentially the number of losses, or some irregular overheads. A second thread of the literature spotlights on the impact of natural disasters on macroeconomic pointers. Auffret (2003) examined the impact of natural catastrophe on Latin America and the Caribbean, and figured out the impact very considerable, particularly for the Caribbean, where the explosive nature of expenditure is higher than in other parts of the world, where insufficient risk-management instruments have been available in the region. This part of the literature has been still conflicting to some extent. For example Benson and Clay (2003) have also explained that the lasting impact of natural events on economic development of any country is negative, while Skidmore and Toya (2002) reveal that such tragedies may also have a constructive impact in the future growth, resulting from a decrease to returns to physical assets but an enlargement in human capital. Strobl (2008) discovers for the US coastal counties that cyclones cut districts intensification at first by 0.8 per cent, at the same time as recuperating after in 0.2 per cent. This writer also figures out for Central America and the Caribbean that the impact from a unhelpful storm is a decline of 0.8 percent of fiscal increase (Strobl, 2008a). When investigating what extra features cut or amplify the impact of such natural tragedies on macro pointers, Kahn (2005) and Toya and Skidmore (2007) explain that organizations, top education and trade openness, in addition to well-built economic segment and smaller governments are significant aspects in shaping the impact that natural events have on growth at global level. The third tributary of the literature takes care of the impact and coping means for such tragic events generally at the domestic and township levels. At this point, natural adversities are upsets that family units have to face as they are unpleasant proceedings leading to a decline in earnings or utilization, and in addition a loss in industrious property. Alderman et al (2006) by means of data for family units in Zimbabwe spotlighted on height growth of kids as result of a deficiency and civil war in Zimbabwe, result that kids influenced by such upsets have less schooling and could have been tall; if not. Dercon (2004) focused on development in utilization amongst family units in chosen villages in Ethiopia, and did not discover that upsets have an effect in the diminution of assets. Carter et al (2007) examined the impact of droughts in Ethiopia and of cyclone Mitch in Honduras on development of belongings at the village level. For Ethiopia they uncover a model of assets leveling between low income family units, i.e. such families keep hold of their assets even they are little in phases where profits and usage drops off, for instance the big deficiency aroused. They discover for Honduran families that comparatively well-off families recovered earlier from the upset than short income households, and that a poverty corner is put below a specified point of income. Baez and Santos (2007) also examined the sound effects of Mitch on households pointers, discovering no outcome on school admissions of kids, but a noteworthy add to their labor contribution. Others have investigated how some coping methods inside families have an effect on revival from a shock resulting from such an adversity. De Janvry et al (2006) explains that uncertain cash transfer accessibility before a disaster provide as a shelter for those who are affected, while those dependent and helpless people utilize as coping method an add to child labor, and savings in food and school expenses. Alpizar (2007) also discovers that access to proper economic services takes the edge off pessimistic outcomes from natural disaster upsets for farmers in El Salvador, as it leads to further proficient production. On the other hand, a less urbanized region is the impact at local level. Yamano et al (2007) explain about industries and production. These writers makes use of region-wise data for employment and production, guessing that financial fatalities are not in proportion to the sharing of manufacturing activities and people attention, signifying that strategies to improve losses should be measured from a top order. Burrus et al (2002) also examined how low intensity typhoons can shock local financial systems from side to side interruption of actions. They exercise statistics from the local Chambers of Commerce surveys and as a result of their regularity the bang could be a decrease between 0.8 and 1.23 per cent of yearly production and up to 1.6 per cent of local employment. Though, there is a slit in the study of how local communal indicators are exaggerated by natural events. This is significant to bring to the front as the effects give the impression of being stretch around all unlike points, macro, micro and local, and how strategies to deal with those upsets can be premeditated in a good way. Whereas families emerge as the natural component of investigation for researching the consequences of natural disasters, it can also seem right to balance the study up as families react to risks are frequently influenced by the broader strategy framework. Certainly, households have substantial and insubstantial assets at their clearance, and their capability to preserve or gather together such assets in such situations will be produced by the arrangements and procedures for instance governance and institutional planning, broader strategies and open circumstances at metropolitan and district level. Additionally, the experience of family units to danger loss can and has been conventionally balanced up to top levels of aggregation (UNDP, 2008). It is the number of citizens situated in definite parts joint with the individual, material and ecological conditions of families and the regions where they live that forms their communal potential to deal with a natural disaster. For that reason, we refer to the community level of study while thinking of the inferences that dangers can have. Governments have a tendency to go on board in various approaches to deal with natural happenings. In the past, they have usually reacted through disaster relief, but more lately there has been a propensity to highlight cash transfers as well. Even if both methods are adopted extra efficiency could be consummate by adopting danger diminution and improvement means that deal with the structural aspects which make families more uncovered to natural risks. Having system in position previous to the awareness of dangers is primary. At the macro level, premature warning systems and the public disaster-preparedness agenda look as if mostly significant, so as sufficient economic assets to promote revival, over and above tax inducements for households or public to take on mitigation procedures. Another type of protecting the value of material goods at the macro level could be through financial diversification. Increasing primary, secondary and tertiary sector activities along with spatial activities in the economy, can offer an open pool to multiply the risk of anguish danger losses, and extra prospects to amplify and steady profits. Equally, the concentration of financial and sector-wise activities would be reliable with condensed capability of families to administer and react to natural disasters. Still, there is a set of insubstantial facts which might improve the family hard work to get through the outcome of natural vulnerability on them, just as adverse socio-economic opportunities. The political economy and organizational aspects of the situation where assets are positioned together with the system of belief, norm and ideas set in the activities of communities members might bear out elementary while utilizing and mobilizing assets for confronting disasters. If possible, one should be capable to clarify how civilization and supremacy provision come into play when they act together with the broader surroundings of risks, assets and wellbeing results. However, most of these features will be tough to get into work empirically for the period of our technical study. Flourishing coping against natural disasters is difficult to achieve in a situation of small efficiency, staled financial development, not having access to industrious possessions, deficiency of economic reserves and safety nets in place, and broad difference crossways geographic, financial, or tribal lines. Lack of health conveniences, remoteness and low rate of education may also complex these susceptibility. Consequently, the covariate life of various natural hazards and the policy-tempted macro circumstances upsetting the rate and likelihood of effectively coping with them might reflect unreliable welfare shocks across region and sub-region levels. At last, societies can make worse these natural, site and practice-specific aspects through not making any investment in substantial and communal infrastructure at the household and district level (roads and bridges). In case of rural areas, these deficiencies can be multifaceted by a high frequency of hazards because of being covered hazard-prone areas, extending the vulnerability of families to experience any losses. Although the impact a natural disaster is an outside factor, susceptibility of causes, making the shock of the event high or low, is not. Susceptibility to natural hazards is a composite subject, as it is determined by the monetary model, the phase of growth, current social and fiscal situation, coping means, risk evaluation, rate of recurrence and greatness of hazards, etc. Lindell and Prater (2003) summarize the significance of shaping the impact and the influenced agents in natural hazards. First, that information is helpful for policy makers, as they can recognize the need for outside support and which may be extra effectual. Second, exact sections of affected can be recognized, e.g. how short income families are influenced, uniqueness of regions etc; and third, it may be also helpful for setting up backing for natural hazards and the possible penalty. They also summarize how the impact of natural hazards should consider other means. One of the main questions concerning the impact of natural hazards on families or towns is how accidental they may be. Donner (2007) examined the effects of hurricanes in the US and figured out that the effects are not accidental, because some aspects such as ecological, society, demographic, and scientific, have an occurrence on the impact of such events. On the whole the flow of impact of natural hazards can be sketched as in Figure 1. figure1.PNG Figure 1. Model of Disaster Impact Other aspect is how establishment have defined practices concerning natural events and how they systematize help in the outcome can also be determinant of the crash. Such as, Peacok and Girard (1997) explain how the revitalization process after tornado in Florida was determined more by governmental obstructions rather than lack of resources. Limited Literature is available which studies the quantitative relationship between the economy and the natural disasters. Zarrar et al (2009) studied the impact of natural disasters on the Irans Gross domestic product. They adopted a auto regressive distributed Lag model in order to study the impact. The findings showed that natural disasters have negative impact on the GDP per capita and on Per captia investment. The result of the model test was that investment had a positive impact on the economy while negative impact on GDP from the damages from the loss of Physical capital. Macro economic variables determine the impact of these natural disasters on the long run economic growth. Aaron (2007) found that financial crises caused by these disasters hurt the long run growth through inflation. This inflation is the result of increased debt burden. Other reason for this inflation could be that central bank print excess notes to pay the external and internal debt. Also the tax collection is also affected which hurdles the government efforts in compensating the losses. However the loss in revenue is compensated by the help of the Loans and aid given by the international institutions. They include the World Bank, International Monetary Fund and the European Union. These loans and aid influence the economic growth in the short as well as the in the long run. Pelling (2002) in his work identified that the most important macroeconomic impact of natural disaster can be studied by examining the inflation trends in the economy. More over the public expenditures by the government and the aid flowing as foreign direct investment influences the GDP growth rate. The used a comparative analysis technique of comparing different case studies to determine the macro-economic effects. These effects are measured by plotting the trends in GDP against macro economic factors i.e Inflation ,FDI and Loans. The literature review discusses the direct and indirect impact of economic variables on the economy. However in this research work only the impact of macro economic variables is studied. From the support of Literature review the macro economic variables which can be used to measure the quantitative impact of natural disasters on the GDP growth of Pakistan are Inflation, Internal and external debts, Foreign Aid and foreign direct investment flowing in the country. In next section of research we will take into account the above macroeconomic variables with the purpose of concluding the impact of natural disasters on the economy of Pakistan. Methodology Research Type In order to identify the macroeconomic effects of disasters, we suggest comparing a counterfactual situation ex-post to the observed state of the system ex-post. This involves assessing the potential trajectory (projected unaffected economy without disaster) versus the observed state of the economy. This contrasts with observing economic performance post-event and actual performance pre-event, as usually done in similar analysis. Our analysis requires projecting economic development into a future without an event. In short, the type of research would be purely Quantitative. Sources of Data Our two main sources of Data are: The open-source EMDAT disaster database (CRED, 2008) maintained by the Centre for Research on the Epidemiology of Disasters at the Università © Catholique de Louvain. The proprietary Munich Re NatCat Service database. Data type and Research Periods Our sample consists of all major natural disaster events during 1950-2010. The sample is based on information from two databases and was compiled by Okuyama (2009) with the threshold for a large event defined arbitrarily to a loss exceeding 1 percent of GDP.One database is the open-source EMDAT disaster database (CRED, 2008) maintained by the Centre for Research on the Epidemiology of Disasters at the Università © Catholique de Louvain. Primary data are compiled for various purposes, such as informing relief and reconstruction requirements internationally or nationally, and data are generally collected from various sources and, including UN agencies, non-governmental organizations, insurance companies, research institutes and press agencies. The other database is the proprietary Munich Re NatCat Service database, which mainly serves to inform insurance and reinsurance pricing. We focus on the monetary losses. In both datasets, loss data follow no uniform definition and are collected for different purposes such as assessing donor needs for relief and reconstruction, assessing potential impacts on economic aggregates and defining insurance losses. We distinguish between sudden and slow onset events. Key sudden-onset events are extreme geotectonic events (earthquakes, volcanic eruptions, slow mass movements) and extreme weather events such as tropical cyclones, floods and winter storms. Slow-onset natural disasters are either of a periodically recurrent or permanent nature; these are droughts and desertification. We broadly associate the loss data with asset losses, i.e. damages to produced capital. This is a simplification, as indirect impacts, such as business interruption, may also be factored into the data. Yet, generally, at least for the sudden onset events, analysts generally equate the data with asset losses, and an indication that this assumption can be maintained is the fact that loss data are usually relatively quickly available after a catastrophe, which indicates that flow impacts emanating over months to years are usually not considered. Losses are compared to estimates of capital stock from Sanderson and Striessnig (2009), which estimated stocks using the perpetual inventory method based on Penn World table information on investments starting in 1900 and assuming annual growth and depreciation of 4 percent. Theoretical Framework and variables under consideration Theoretical Framework to be used in this essay to explain Economical Impacts on Pakistan due to Natural Disasters. Economical Impacts GDP Exposure Socioeconomic Susceptibility Direct Risks Produced Resources Environment Resources Human Resources Type of Hazard Physical Susceptibility Risk Management The literature on the monetary impacts explained can be associated with framework above. Independent Variables: Independent Determinants of such impacts and dangers can be renowned as: Hazard Variable: This variable is related to the type of Natural disaster/Hazard that jolts any part of Pakistan. Exposure: This variable deals with the geographical area and spatial scale of impact from the particular disaster. Economical Structure: This variable deals with the overall structure of the economy in the country and in particular region affected by the disaster (if needed). Development: This determinant deals with risks that might directly or indirectly affect the stage of the development of the country. Socioeconomic Environment: It is related to the current socioeconomic conditions in the country. Risk Management: This takes care of the availability of formal and informal mechanisms to share risks in a particular part of the country. The last four variables are related to economic susceptibility. Research Hypothesis H0: Natural Disasters do not have any significant negative follow-on effects on the economy of Pakistan. H1: Natural Disasters do have significant negative follow-on effects on the economy of Pakistan. Techniques We use autoregressive integrated moving average models, also called ARIMA (p,d,q) (Box and Jenkins, 1976) for forecasting GDP into the future after the disaster event. ARIMA modeling approaches are chosen because they are sufficiently general to handle virtually all empirically observed patterns and often used for GDP forecasting (see for example Abeysinghe and Rajaguru, 2004). While such a type of modeling may be criticized for its black box approach (Makridakis and Wheelwright, 1989), it here serves well due to the large number of projections to be made and the difficulty identifying suitable economic model approaches. The ARIMA process Recall, an autoregressive process of order AR (p) can be defined as x t = à â⬠1x tà ¢Ãâ ââ¬â¢1 + à â⬠2x tà ¢Ãâ ââ¬â¢2 ++ à â⬠px tà ¢Ãâ ââ¬â¢p + ÃŽà µt A moving-average process of order MA (q) may be written as xt =ÃŽà µ t +ÃŽà ¸1ÃŽà µ tà ¢Ãâ ââ¬â¢1 +ÃŽà ¸ 2ÃŽà µ tà ¢Ãâ ââ¬â¢2 +à ¢Ã¢â ¬Ã ¦+ÃŽà ¸ qÃŽà µ tà ¢Ãâ ââ¬â¢q and an ARMA(p,q) process, with p autoregressive and q moving average terms can be defined to be xt =à â⬠1xtà ¢Ãâ ââ¬â¢1 ++à â⬠p xtà ¢Ãâ ââ¬â¢ p +ÃŽà µ t +ÃŽà ¸1ÃŽà µ tà ¢Ãâ ââ¬â¢1 ++ÃŽà ¸ qÃŽà µ tà ¢Ãâ ââ¬â¢q Where à â⬠and ÃŽà ¸ are parameters to be estimated and ÃŽà µ are white noise stochastic error terms. Now, let yt be a non-stationary series and define the first order regular difference of yt as ÃŽâ⬠yt = yt à ¢Ãâ ââ¬â¢ ytà ¢Ãâ ââ¬â¢1 or more generally using a back-shift operator denoted as Bk zt = ztà ¢Ãâ ââ¬â¢k yt B d yt ÃŽâ⬠d = (1à ¢Ãâ ââ¬â¢ ) An ARIMA (p,d,q) model can then be expressed as yt q B t B B d à â⬠p ( )(1à ¢Ãâ ââ¬â¢ ) =ÃŽà ¸ ( )ÃŽà µ with B p à â⬠p (B) = 1à ¢Ãâ ââ¬â¢Ã â⬠1B à ¢Ãâ ââ¬â¢Ã ¢Ãâ ââ¬â¢Ã â⬠p and Bq ÃŽà ¸ q (B) = 1à ¢Ãâ ââ¬â¢ÃŽà ¸1B à ¢Ãâ ââ¬â¢Ã ¢Ã¢â ¬Ã ¦Ã ¢Ãâ ââ¬â¢ÃŽà ¸ q Data Analysis The Box-Jenkins methodology (Box and Jenkins, 1976) is applied for determining the components of the ARIMA process; i.e. we test different ARIMA(p,d,q) models with p and q to be smaller or equal 4 (due to the limited amount of data) and estimate à â⬠and ÃŽà ¸ using Maximum likelihood techniques and the Akaike Information Criterion (AIC) as well as diagnostic checks to detect a suitable model. The data requirements were set thus that at least 5 observed data points are needed for projections into the future. This is the smallest number of observations which are needed to estimate ARIMA (4,1,4) models (however, the majority of the sample (greater 90 percent) has at least 10 data points). Furthermore, all models are tested to be stationary (usually d=1 suffices to assure a stationary process) and all series are demeaned. To include uncertainty in the projections, also 95 percent confidence forecasts were calculated and analyzed. Forecasts into the future are performed with the selected models and then compared to the observed variables. Increases or decreases of GDP in future years are measured as a percentage increase or decrease to baseline GDP (i.e., baseline =100) which is defined to be GDP a year before the disaster event. Furthermore, the differences between observed values and projected ones are calculated and called Diff(t), which indicates the percentage difference between the observed and projected value of GDP in year t. We focus on projections with a medium term perspective (up to 5 years into the future). This limitation is due to important data constraints for the ARIMA models within

An Inspector Calls - Priestleys Presentation of the Inspector Essay
An Inspector Calls - How does Priestley's presentation of the Inspector create dramatic tension in the play? 'An Inspector Calls' Question Title: How does Priestley's presentation of the Inspector create dramatic tension in the play? During the play 'An Inspector Calls' the Inspector is used as a dramatic device. He raises and decreases the tension due to his attitude, actions, speeches and his symbolic role to the family, and audience at the time when the play was first performed. Throughout my essay I will be examining how Priestley's presentation of the Inspector generates tension throughout the play. Before the Inspector is introduced into the play, the atmosphere in the Birling's house is quite relaxed. They are celebrating Sheila and Gerald's engagement, so there is a party atmosphere and dull lighting. The stage directions describe the situation as: "At the moment they have all had a good dinner, are celebrating a special occasion, and are pleased with themselves." The Inspector's arrival disrupts the family's celebration; this automatically raises the tension, because the family would be annoyed by the abrupt interruption of their celebration. When the Inspector first rings the doorbell, Birling is just finishing one of his arrogant speeches. He has just said: "a man has to mind his own business and look after himself and his own." This is significant in relationship to the play because Birling's original views are exactly what Priestley, through the Inspector, is trying to teach the audience not to think like. Birling is the kind of person who Priestley is trying to get through to. The atmosphere is also made uneasy because no one knows definitely why the Inspector has called bu... ...r classes and the way that the Inspector brought these ideas crashing down. In the 1954 film version of the play the man who plays the Inspector is a pale faced man with dark dramatic eyes. This makes the Inspector look ghostly enforcing some peoples theories of him being a ghost. Because the Inspector's true identity is not revealed the tension in the play is increased. This is because the audience don't know anything about the Inspector, so do not trust the inspector and there-fore would be put on edge by him. Priestley has presented the Inspector in a very mysterious way, we do not know where he comes from or anything about him, but it is soon made clear why he is in the play; to teach an important lesson. The audience is left thinking about the play and all the issues raised in it. This play definitely left me thinking about my role among society.
