Number of Supreme Court Nominees By President - List

President Barack Obama successfully chose two members of the U.S. Supreme Court and has a chance to nominate a third before his term ends after 2016. If hes able to push a candidate through what can be a politically charged and sometimes lengthy nomination process, Obama will have chosen a third of the nine-member court. So how rare is that? How many times has a modern president gotten an opportunity to choose three justices? Which presidents have nominated the most Supreme Court justices and had the largest impact on makeup of the highest court in the land? Here are some questions and answers about the number of Supreme Court nominees by president. How did Obama get the chance to nominate three justices? Obama was able to nominate three justices because two members of the Supreme Court retired and a third died in office. The first retirement, that of  Justice David Souter, came a short time after Obama took office in 2009. Obamas chose Sonia Sotomayor, who later become the first Hispanic member and third woman justice to serve on the high court. A year later, in 2010, Justice John Paul Stevens gave up his seat on the court. Obama picked Elena Kagan, a former Harvard Law School dean and solicitor general of the United States who was widely seen as a consensus-building liberal. In February 2016, Justice Antonin Scalia died unexpectedly. Is It Rare For a President to Get to Nominate Three Justices? Actually, no. Its not that rare. Since 1869, the year Congress increased the number of justices to nine, 12 of the 24 presidents preceding Obama successfully chose at least three members of the Supreme Court. The most recent president to get three justices on the high court was Ronald Reagan, from 1981 through 1988. In fact, one of those nominees, Justice Anthony Kennedy, was confirmed in a presidential-election year, 1988. So Why Were Obamas 3 Nominees Such a Big Deal? That Obama had the opportunity to nominee three Supreme Court justices was not, in an of itself, the big story. The timing — his final 11 months in office — and the impact his choice would have on setting the ideological course on the court for decades to come made his third nomination such a big news story and, of course, a political battle for the ages. Related Story: What Are Obamas Chances of Replacing Scalia? Which President Has Chosen the Most Supreme Court Justices? President Franklin Delano Roosevelt got eight of his nominees on the Supreme Court over the course of just six years in office. The only presidents who have come close are  Dwight Eisenhower, William Taft and  Ulysses Grant, whom each got five nominees on the court. So How Does Obamas 3 Picks Compare to Other Presidents? With three picks for the Supreme Court, Obama is exactly average. The 25 presidents since 1869 have gotten 75 nominees on the high court, meaning the average is three justices per president. So Obama falls right in the middle. Here is a list of presidents and the number of their Supreme Court nominees who made it to the court since 1869. The list is ranked from presidents with the most justices to those with the least. Franklin Roosevelt: 8 Dwight Eisenhower: 5 William Taft: 5 Ulysses Grant: 5 Richard Nixon: 4 Harry Truman: 4 Warren Harding: 4 Benjamin Harrison: 4 Grover Cleveland: 4 Ronald Reagan: 3 Herbert Hoover: 3 Woodrow Wilson: 3 Theodore Roosevelt: 3 Barack Obama: 2* George W. Bush: 2 Bill Clinton: 2 George H.W. Bush: 2 Lyndon Johnson: 2 John F. Kennedy: 2 Chester Arthur: 2 Rutherford Hayes: 2 Gerald Ford: 1 Calvin Coolidge: 1 William McKinley: 1 James Garfield: 1 * Obama has not yet nominated a third justice, and it remains uncertain whether his choice will will confirmation.

Research Paper on Scrap Metal Trade in Jamaica Free Essays

Introduction The scrap metal trade is a very controversial topic in Jamaica in recent times. Outside of registered dealers/traders, the industry has garnered interests from many others as it has become a way of life for providing quick income for households. Although the trade started out as a livelihood for these persons the paradigm has shifted and now stems more negatives than positives as unscrupulous persons has used it as an avenue to participate in illegal activities that resulted in the government (Dr. We will write a custom essay sample on Research Paper on Scrap Metal Trade in Jamaica or any similar topic only for you Order Now Christopher Tufton – Minister of Industry, Investment and Commerce at the time) instituting an indefinite ban on the Scrap Metal trade in Jamaica in July of 2011. Jamaica has had a number of reported cases of theft of valuable equipment and infrastructure over the last four years amounting to approximately $1 billion (Barrett, 2011). It is for this reason many argue this industry is doing us more harm than good. Scrap Metal theft however is not exclusive to Jamaica; it is a global concern and has been for the past 10 years. Kooi (2010) articulates that the rise in Scrap metal theft is driven by offenders’ recognition that ample metal supplies remain unguarded and that the price of return remains historically high based on heavy international demand. The market conditions made unsecured metal susceptible to increased theft, while causing a boom in scrap metal exports that increased the scrap metal theft problem. It is evident that the scrap metal trade offered both positives and negatives to our country’s economy. It has provided job opportunities to many youths and has given them a sense of achievement as the income allows them to positively contribute to society and their families. It has also been the largest contributor in earnings to the export section â€Å"Crude Materials† for many years (STATIN, 2012). There has been some discourse from the new Minister of Industry, Investment and Commerce Andrew Hylton on reopening the trade with tough new regulations. This is controversial as the industry is earning less than the losses associated with it. This research seeks to address the questions: 1) What is the public’s sentiment on this controversial issue being faced by our country? 2) How great an effect does legislation have on illegal trading of Scrap Metal presently? 3) Does the problem exist in enforcement of the legislation in place for the Scrap Metal Industry? 4) What punishment measures are in place presently and do they differ from what Jamaican people want in place for Scrap Metal Theft? Statement of the problem: There has been a tremendous level of theft of infrastructure reported from private companies being traded illegally. The focal point of this research is to explore the influence of legislation, enforcement (or lack thereof) of this legislation and punishment measures on illegal trading of Scrap Metal. Significance of the study: The contribution of the Scrap Metal trade to Jamaica’s earnings is significant, however the losses from theft and illegal trading supersedes its gains. It’s been over a year since the ban was instituted on the Scrap Metal trade and many are still suffering. The placard of a protester (someone who used to have a livelihood from collecting scrap metal) in Riverton Meadows last November read â€Å"When we have no work our kids are robbed of their future† (Jamaica Observer, November 9 2011). It’s hard not to be concerned about the future of our children. But it is also hard to see the detriment this is causing our nation â€Å"Bridges? Water Pipes? Telephone cables? Railway lines? Gates? Road Signs? Not even the dead are spared as these worthless scavengers dig up graves in order to rob the coffins of metal handles. (Editorial – Jamaica Observer July 28 2011, para. 2). As a developing nation, we need to foster growth in all our sectors but at the same time we need to be operating in public interest and for the good of the whole instead of only in the interest of particulars. Hence, in order to act in support of the livelihoods of our people and protect our infrastructure, while fostering growth within the Scrap Metal t rade sector, it is adamant that studies like this are done to look at reducing illegal trading. Research Question: What protocol can be established to minimize illegal trading in the Scrap Metal Industry of Jamaica? General Research Objective: To determine the extent to which legislation, enforcement of the legislation and punishment measures may influence illegal trading of Scrap Metal in Jamaica. Other Objectives: * To generate a public poll on this controversial issue being faced by our country. * To investigate how great an effect legislation has on illegal trading of Scrap Metal. * To examine if the problem exists in enforcement of the legislation in place for the Scrap Metal Industry. To determine what punishment measures the Jamaican people want in place for Scrap Metal Theft. General Research Hypothesis: Better legislation, enforcement and punishment measures will have a strong negative impact on illegal trading of Scrap Metal in Jamaica. Sub Hypotheses: The higher the level of legislation put in place for Scrap Metal Dealers, the lower the level of illegal trading. The higher the level o f enforcement of the legislation in place for the Scrap Metal Industry, the lower the level of illegal trading. The higher the level of punishment measures for Scrap Metal theft, the lower the level of illegal trading. Independent Variables Dependent Variable Illegal Trading Legislation Enforcement Punishment Measures Illegal Trading Legislation Enforcement Punishment Measures Literature Review This section contains a review of literature that is related to the concerns of this research paper as well as the conceptualisation of variables chosen. The literature will provide a layout and critical analyses of what has already been researched in relation to the Scrap Metal Trade Industry here in Jamaica as well as abroad. It is our hope that the literature review will provide a broader perspective on this very pertinent issue being faced by our country today. According to the Ministry Paper Trade Regulations for the Scrap Metal Industry Italy experienced severe delays in the train system due to the theft of copper wires and a number of states across the United States have also been reporting theft of copper wires that support their commercial infrastructure. This paper further states that the Caribbean countries Dominican Republic and Guyana have also experienced increased criminal activities related to scrap metal industry whereby Guyana is considering banning the export of the product altogether in an effort to stop the damage that it is causing the country’s infrastructure and other productive sectors. In recent years however, the problem has been a growing concern in Jamaica. â€Å"Prior to 2003, the scrap metal trade in Jamaica was more or less limited to a small domestic market and, consequently, the impact of scrap metal theft on other sectors was not significant†. CAPRI Policy Brief B122, January 2012 p. 4). However the article further stated that â€Å"A noticeable increase in scrap metal theft coincided with the sudden rise in scrap metal prices in 2003†, as there has been an increasing growth in the export market, increasing from US$13. 3 million in 2005 to US$99. 58 million in 2006. As a result, â€Å" a n interim response to the issue an Order, entitled â€Å"The Trade (Prohibition of Export) (Scrap Metal) Order 2007† was gazetted on October 31, 2007 to temporarily prohibit all exports of scrap metal until trade regulations are introduced. The Order recognized shipments already â€Å"entered† for export into the Customs Department system up to October 30 th 2007. (Ministry Paper Trade Regulations for the Scrap Metal Industry) The Government has banned the multi-billion dollar scrap metal trade. Dr. Christopher Tufton, the Minister of Industry, announced the ban at a press conference Tuesday afternoon in July of 2011. Dr. Tufton said the ban came against the background of the widespread theft of metals over the past three years as well as the warnings to scrap metal dealers to implement measures to curb the illegal activities in the trade. Jamaica and other countries to include different states in the United States of America recommended various policies to regulate the scrap metal trade and how to minimize illegal trading. The scrap metal trade in Jamaica does not require a copy of the seller identification be taken and kept on records by the purchasing of dealers. However the 2007 Wisconsin Act 64, requires scrap metal dealers to ask for identification and proof of ownership. The Act further stated that â€Å"seller and deliver of metals must provide motor vehicle operator license, current photograph identification which includes the person’s full name, current address, date of birth and identification number†. The Caribbean Policy Research Institution at the University of the West Indies in Mona also support this act in its â€Å"10 steps to Scrap Metal Solution† as policy 3 require that a â€Å"copy of the seller’s identification be taken and kept on record by the purchasing dealer†, and pointed out that this would ensure that a paper trail is created for transaction at the origin. Currently the Jamaica laws do not furnish a specific punishment for metal theft. However, the B. C. government is hoping to reduce metal theft, with new legislation that requires scrap metal dealers to report them to the police. Under the proposed law dealers will have to record the names and addresses of metal sellers and where the sellers got the material, and pass this information on to the police (Renzetti, London â€Å"The Globe and Mail†, July 2012). On the other hand responses in Kooi article recommended Offering reward money for tips on metal thieves. This way Police, crime prevention organizations, or companies victimized by scrap metal theft can establish hotlines and offer reward money for tips about suspected scrap metal theft. (p 31) Methodology This section will present an overview of the methods that were employed in conducting this research. Research design, population and sampling as well as the instrumentation used for data collection will be the areas of discussion. Research Design Due to the nature of the research, descriptive research was undertaken. It is felt by the researchers that this type of research was the most suitable for the topic under scrutiny. Our research is descriptive in the fact that we merely wish to observe the public’s sentiment on the issue as well as the reasons for the downfall of the scrap metal trade industry in Jamaica. The researchers do not intend to change the way Scrap Metal is traded; instead we have sought to obtain a general overview on the extent to which legislation, enforcement of the legislation and punishment measures may influence illegal trading of Scrap Metal in Jamaica. Due to the short time frame that the research was done in, it took the characteristics of a cross sectional study which takes a snapshot of the population at a given time (August – September 2012). The researchers engaged in qualitative methods of gathering data, where questionnaires were administered, an interview was conducted and previous researches on the topic were utilized. Population Sampling Non-probability sampling was applied to the research, specifically Judgemental/Purposive sampling. Due to our research topic, the population being looked at was residents of Kingston, Jamaica who were perceived to be informed on the topic. Within that population our target groups were members of the Jamaica Constabulary Force, employees of the Ministry of National Security, Truckers/Collectors of Scrap Metal and general working professionals (public sector workers, Physicians, Educators, members of the Research and Economic Programming Division of the Bank of Jamaica, Students and the Self-employed). Our proposed target sample size was 100 persons, however, after 100 questionnaires were administered, only 86 questionnaires were returned. Some respondents failed to answer all questions on the instrument therefore for those questions not answered, (e. g. Questions 4, 9, 10-12) their sample size was reduced by three, four and three respectively. Instrumentation for Data Collection Due to the nature of the research topic, qualitative research in the forms of questionnaires and an interview was used to collect data. The questionnaire consisted of twelve questions of both open-ended and closed-ended response formats. There were only two open-ended response format questions (questions 1 and 9(partially) -please see appendix for a copy of the instrument). The closed-ended response format which the rest of instrument demonstrated provided fixed responses. These responses used mainly nominal ranking (e. g. Questions 1-6, 8-12) and also ordinal (e. g. Question 7). The questionnaire’s purpose was to adequately obtain the respondents’ opinions about the relationship between the independent and dependent variables outlined for this research. The combination of questions all addressed concepts such as the public’s opinion on the ban placed on the Scrap Metal Industry, where they thought the weakest link in the trade was, rules and regulations in place and punishment measures for Scrap Metal theft . An interview was conducted with a Mr. Derrick Mitchell on Wednesday, September 05, 2012. Mr. Mitchell is a licensed dealer in Clarendon and operates Mitchell’s Scrap metal. This interview consisted of open-ended questions which gave him ample freedom in his responses (please see appendix for a copy of the questions asked). In addition, electronic research as well as a thorough overview of this very current topic in the media was employed to aid in background information discussed in the literature review and throughout this paper. Findings and Discussion After giving some background to the topic of interest by reviewing relevant literature, providing the conceptualization and operational definitions of our variables, discussing how the sample was chosen and the instrumentation used to obtain data, this section will now look at our results from the interview conducted and questionnaires administered and returned. Interview Results He stated that the government is responsible for closing down the trade and that there are poor regulations in the monitoring system. He also mentioned that the customs officers are not fully monitoring the containers as they often leave the container open over night that will attract the criminals to load on illegal metals or metals that they are not licensed to be traded. He mentioned that each dealer should have license that allows them to trade various types of metals but because of the theft if gets them into trouble as there containers will be found with metal that they should not be trading. Mr. Mitchell mentioned that if the customs officers were caring out there duties properly they would detect the illegal metals before export. He recommends that instead of having one central site ( as is being proposed in the new regulations by Minister Andrew Hylton) that the government look at setting up regional sites as this may be more feasible for the rural traders. Transporting metal to the central site for checking will quickly become a costly burden for traders. Survey Results Findings There were one hundred questionnaires administered and eighty-six returned. Below are the results from the survey: Figure 1 below shows the public sentiment on the ban placed on the Industry which relates to question two of the questionnaire administered. It is evident why this issue is as controversial as it has been in recent times as the responses indicated almost a 50/50 split in opinion. 52% of respondents feel that the ban should not be lifted, while 48% feel it should be – one of this 48% exclaimed â€Å"We must recycle! Measures need to be put in place to protect the industry! † Figure 2 goes further to demonstrate how the public feels about the industry and who is to blame for the problems associated with it. This relates to question three of the questionnaire. Majority of the respondents believe the problem lies at the point of collection/scrap yards. Legislation Figure 3 relates to question eight of the questionnaire. It shows that 91% of the respondents think that Scrap Metal dealers should send a list of all metals purchased to the police in order to trace potentially stolen material. Figure 4 and 5 related to question eleven and twelve respectively. The answers to these questions were directly related. 81% of the respondents think the ban should remain on copper since it is a high target metal for theft, however that same 81% also believed that allowing select dealers only in the trade of copper was a smart alternative. Enforcement Figure 6 (relating to question six on the questionnaire) and Figure 7 (relating to question seven of the questionnaire) is showing that 93% of the public believe that rules and regulations need improving, and almost all respondents think there are â€Å"too little† measures in place currently. However, Punishment Measures Figure 8 shows the responses to question nine of the questionnaire. It alludes to how the public feels about Scrap Metal theft. Most respondents believed that being confined behind bars is the most appropriate punishment while at a close second was the punishment of paying a fine. This question also included an open-response format which allowed people to speak freely about their opinion on necessary punishment measures. Some of these responses included: â€Å"Entity suffering from the theft should be compensated to replace item†, â€Å"Person should provide labour (with stipend)to whomever was affected at the cost of the stolen metals†, â€Å"Standard meaningful fee for all, a thief is a thief – big or small! † and â€Å"Hard Labour Community service†. There were also suggestions of â€Å"Death Penalty† and â€Å"Life in Prison†, which indicate that people need the punishment measures for scrap metal theft to have some power of intimidation for these thieves. Conclusion (Answers to our sub research questions below) 1)What is the public’s sentiment on this controversial issue being faced by our country? 2)How great an effect does legislation have on illegal trading of Scrap Metal presently? 3)Does the problem exist in enforcement of the legislation in place for the Scrap Metal Industry? 4)What punishment measures are in place presently and do they differ from what Jamaican people want in place for Scrap Metal Theft?

Love in The Hunchback of Notre Dame free essay sample

Love in The Hunchback of Notre Dame In the book The Hunchback of Notre Dame the author, Victor Hugo, used love as a central theme for his book. He showed that love can manifest itself in three main ways depending upon the person. Esmeralda was in a mode of self- destruction because of her lust for Phoebus. Claude Frollo turned into a man of Jealous rage because of his amorousness for Esmeralda, and Quasimodds passion for Esmeralda crumbled his heart as if it was made of stone, because of her death. Hugo used love as a central theme to capture the heart of the reader. He forced his readers to change their perspective on affection and admiration, in ways never thought of before. Hugo used Esmeraldas lust for Phoebus as his first example of how love can manifest itself in many different ways. Esmeralda, blinded by lust only saw Phoebus for what he looked like on the outside. We will write a custom essay sample on Love in The Hunchback of Notre Dame or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page She was very much attracted to Phoebus, a man who was as ugly as a gargoyle on the inside, but as handsome as an angel on the outside. As a result of being blinded by lust, Esmeralda could not see the beauty of Quasimodo on the inside despite his repugnant appearance. Esmeralda had everlasting love for Phoebus and when he died Esmeralda felt as if she had no other reason to live. While talking romantically in a room, Esmeralda said to Phoebus, You are good, you are generous, you are kind; you saved me, me who am but a poor gipsy foundling. I have long dreamed of an officer who should save my life. It was of you I dreamed before I ever knew you, my Phoebus (284). When Phoebus was taken from Esmeralda, it was like taking water from a fish. She could not operate properly, and she soon fell into a state of self-destruction. Even while being tortured Esmeralda still muttered the name of Phoebus. Esmeraldas love for Phoebus destroyed her. She fell deeper into a pit of depression, self pity, and self destruction. Victor Hugo used Claude Frollos amorousness for Esmeralda as his second example of how love can manifest itself in different ways. While in the dungeon where Esmeralda was placed, Claude Frollo said, It was noon, the sun shone brightly, a creature was dancing, a creature so beautiful that God would have preferred her to the Virgin, and be chosen her to be his mother, and had she existed when he was made man (113-144). Claude Frollo found it Just to compare her to the beloved Virgin Mary, the mother of Jesus Christ. Unfortunately, Frollos love for Esmeralda caused him to kill the only man she loved out of Jealousy, hate, and rage. While talking to himself Frollo said, no one else shall have her (372). Surprisingly, when Esmeralda did not want him, he became indirectly responsible for her death. The last and the most important way Victor Hugo showed how love can manifest itself was when he demonstrated the passion Quasimodo had for Esmeralda. When describing the ugliness of Quasimodo Hugo said, The poor imp had a wart over his reastbone prominent, his legs crooked; but he seemed lively (142). Quasimodo had the features ofa gargoyle but the heart of an angel. Unfortunately, Esmeralda was too shallow to look beyond his exterior features. He loved Esmeralda more than he loved himself, and while giving her directions about staying in the church he said, Do not leave the church by day or by night. You would be lost. They would kill you, and I should die (354). He loved Esmeralda too much to live without her. He became intertwined with her heart and soul, like a dog to his master, and if she died, he ould die as well. After Quasimodo saved Esmeralda from death, she asked him why he had saved her, to which he replied, You have forgotten a villain who tried to carry you off one night, a villain to whom the very next day you brought relief upon their infamous pillory. A drop of water and a little pity are more than my life can ever repay (357). Quasimodo loved Esmeralda more than life itself. She was his oxygen and when she died he could not live. Quasimodo refused to live in the same world that was responsible for the death of the only thing he loved, so he voluntarily ended is life. When describing love Hugo said, Love is like a tree; it grows spontaneously, strikes its roots deep into our whole being, and often continues to flourish over a heart of ruins(358). Love is a powerful force that can change someone dramatically for the better or for the worse. In The Hunchback of Notre Dame, by Victor Hugo, the reader learns that love can take on many facets. It can drive a person to self- destruction, it can cause a person to become full of Jealousy and hatred, and cause a person to sacrifice his life, the most valuable thing a person possesses.

7 Reasons Why Slowing Down At Work Is a Good Idea

7 Reasons Why Slowing Down At Work Is a Good Idea You might think the best and most productive worker in the room is the one balancing 17 tasks at once and zooming up and down the halls, but you’d be wrong! It turns out that sometimes the smartest and most successful people are the ones who ease up on the throttle, turn down the pace, and work more slowly and mindfully. Here are just a few ways how a  slower approach to work can pay off hugely in the long run.1. You need more time than you think†¦ to think.It’s hard to do your best cognitive and creative work in the frenzy of the workplace. What if that frenzy were just†¦ pointless, though? If you start to think â€Å"slow,† you’ll give yourself time to ease the pressure, get creative, let your ideas simmer until they’re ready to emerge. Instead of jumping rapidly- and inefficiently- from task to task, try deliberately slowing down. You might be amazed at how much time you actually have in a given day when working effectively instead of in a frenzy.2. Your rational brain kicks in.You’ll be more confident in your ideas and decisions when you make them mindfully. Move away from your super fast automatic or â€Å"sympathetic† nervous system and those knee-jerk reactions, and towards the slower, more logical â€Å"parasympathetic† nervous system. You’ll get out of mental loops and autopilot and come to more logical decisions about which you can be more confident.3. Your listening skills improve.Are you frantically tuning people out, smiling and nodding because you’re just too busy to put down your task and listen? Curb this common behavior and learn to truly process the ideas and concerns of others. You never know when this might help you find the missing piece to a personal puzzle, or gain more respect and traction among your coworkers.4. You’ll make fewer mistakes.Working this way, slowing your pace to be more meticulous and measured, means that you’ll make fewer mist akes. And the mistakes you do make will be much easier to rectify. You might even learn something and have the time and space to internalize that lesson before moving on.5. Your brain will remember how to act.This kind of practice is also great because it will eventually train your brain to slow down and work this way automatically. Soon it won’t be a project, but just the way you work.6.  You can eliminate unnecessary work.Sometimes busy work is just that†¦ busy. Working slowly can help you realize which tasks are not necessary. Save yourself and your coworkers from extraneous work. Don’t create extra tasks for yourself or others when you could concentrate on the projects that really matter.7. You’ll learn to let go of stress.Instead of chewing your nails down to the quick and tapping your feet annoyingly while waiting for coworkers to finish off their tasks, concentrate on the work on your desk. Do it right, rather than fast. And instead of concentratin g on getting everything done, try working just on the task at hand and getting it done right. Relax a little and understand that it’s just not possible to leave work every day with a blank to-do list.

Labor migration and remittances in the middle east

Labor migration and remittances in the middle east Introduction International migration is the movement of people across the global boundaries in pursuit of stability, establishment and personal growth. A research carried out by Alan and Philip indicated that this kind of movement has colossal implications in bolstering growth for both the origin and destination countries (2004.p.56). Advertising We will write a custom research paper sample on Labor migration and remittances in the middle east specifically for you for only $16.05 $11/page Learn More According to Migration and Remittances Factbook almost two hundred million people live permanently outside their country of birth. The two key factors which have a massive implication on the migration partners are demographic factors and income differences. The issue of international migration garners massive advantages to all the parties involved in it however it has got its bottlenecks which must be tackled in order to minimize loss and abuse. In order for cou ntries to reap maximum benefits from intercontinental immigration, disruptive effects should be minimized so as to enhance the developmental impacts. Countries in the Middle East have for the past decade provided cheap labor for the developed countries through immigrants. In return they gain remittances earned by the immigrants based in the developed countries. Opponents of this trend have severely criticized it deeming it as oppressive abusing morality. These sentiments were particularly voiced because most of the learned expatriates were offered degrading menial jobs irrespective of their academic competence. The critics however fail to acknowledge the reality that immigrant literary jump at the opportunity of working in developed countries rather than waste their skills in their mother land where there are no jobs to come by. The past global financial hiccup gradually reduced the rates of immigrations at the same time stalling world economy growth. The big question that begs an answer is that, does immigration garner more benefits to the sending or the receiving country, and therefore should the trend be encouraged or disbanded? Effects On The Receiving Countries Increased economic growth: When the immigrants from developing countries flow into the developed countries such as US, Japan and Australia, they offer labor in the areas where it has been missing or deficient. When they are fully assimilated in the production or manufacturing system they contribute positively through increased labor thus causing the economy to grow.Advertising Looking for research paper on international relations? Let's see if we can help you! Get your first paper with 15% OFF Learn More Increased labor and labor force: Most developed countries are running short of the labor force especially in the technical and computer based jobs. This trend is very prevalent owing to the increased availability of new and modern companies in the event when immigrants come in, they help to fill in the place of missing labor and labor force in the industrial sector. Developed countries have surplus jobs, ranging from menial jobs to professional jobs which need laborers; by attaining easy and available labor from the developing countries, they are able to maximize on their production hence growth and advancement (Angrist Andrian, 2002.p.49). There are shared benefits accrued to movement of labor force through immigrants from the developing countries to the recipient developed countries. The developed countries cheaply obtain skilled labor force and utilize them in the production and the technical based jobs. As Moses (2001) notes, the trend of obtaining labor force from the developing countries is likely to increase due to the increased use of computer technology and the minimal availability of jobs in the developing countries (p.52). Increased technical skills: In essence developing countries import capital from other countries and this expands their production capacities helping them to have bounty in economic growth. There is a notable technological growth in the host countries owing to the influx of technical expatriates from the developing countries. The immigrants bring in the needed technical skills and help in broadening the spread of technical skills in the recipient countries. Reduced cost of production: increased work force afforded by the immigrants help the developed countries in provision of cheap labor in manufacturing and production companies so that their companies have a chance to grow as they can afford to easily expand as they cut down on the production cost. The developed countries have been working in consensus with the developing countries to erase the trade of labor exploitation so that the immigrants cross borders under secure conditions, they are offered good enumerations and that their working conditions are made cheap. This enhances benefit for both the developed and developing countries. In comparis on to other income flows to the developing countries remittance, inflows surpass private capital flows and authorized development aid (Smith Barry, 1997.p.32). When developed countries offer immigrants jobs they help in reducing the borrowing trend associated with the developing countries.

Mora and Taylor (2005) suggest that economic gains accrued to migration and remittances to Middle east countries garner more advantages for both the sending and the receiving countries and should thus be encouraged (p.70) Whilst the developing countries might have surplus labor force owing deficiency in industrial growth, the developed countries offer a solution to this deficiency by availing job opportunities to the immigrants from the developing countries affording them a chance to grow and enhance growth in their mother land. Receiving countries who import labor from the developing countries in the Middle East such as US, Canada and Australia garner myriad benefits since they are able to get the missing labor force from the high skilled immigrants from the developing countries. The immigrants offer a pool of diversified labor force which is normally affordable. The receiving countries afford job opportunities to the in flowing immigrants and this increases their productivity at the same time cutting down on cost of production, two factors which aid to bolster economic growth in the developed countries. Moreover, the presence of immigrants has a trickle effect on the general global economy. Effects On The Sending Countries. When people migrate and take their labor force to another country the trend is termed as brain drain this trend is also termed as human capital flight (Schiff,2002.p.64) There are innumerable reasons why people opt to leave their country of origin to pursue establishment and financial stability in other countries. Some reasons include internal conflicts, lack of job opportunities, presence of health hazards and general economic instability. In Middle East brain drain occurs because people are pursuing better working conditions, and good salary wages in the developing countries. For the past thirty years according to†¦many bright and prospective talented people have moved to developing countries in order to attain stability, security and financial break through. The flow in remittances garners a lot of foreign income for both the sending and the receiving countries. The receiving country obtains labor which translates to income and in return they pay their workers wages which are then siphoned to their country of origin translating to foreign income.

This way the sending countries get direct source of foreign income through the immigrants. Foreign income enables them to advance and embrace growth which would have been impossible without the remittances. Remittance flows cannot be compared to aid flows and neither can they be treated as debts they form a direct source of stability and income to the sending countries. This is because the money is not taxed and neither is it repaired with interest like in the case with debts. Owing to the reduced cost of remittance flows the migrants families reap maximum benefits. When there is foreign income flow into the sending countries the level of consumption increases and this bolsters a country’s credit worthiness. When a country becomes credit worthy it becomes empowered to have external borrowings which furt her aid in economic advancement and growth. Research carried out in Middle East established that immigration improved the level of education in that young people left their countries and went to developed countries where they harnessed advanced education which affords good quality professionals to their home countries (SingerTandon, 1998.p.13). Another key benefit associated with immigration is increased savings which come as a result remittance in flows by the people who migrate to work outside the developing countries. There is also a notable trend of heightened macro economic stability. Stability comes as a result of money flowing from the immigrants in the developed countries. When people in the home countries get the remittances they are empowered to build their lives, acquire good education and improve their way of living. As a result of remittance inflows, in the Middle East people get capital which helps them to start up their own business enterprises hence there is increas ed entrepreneurship with trickle effect on the economic growth of the developing countries. In Middle East where the trend of poverty is highly prevalent, remittances help to assuage this trend since it affords people extra money which heightens their chances to acquire businesses or educational stability evading the pang of poverty. There is notable social inequality in the Middle East owing to diversity in culture and the myriad cultural factors miring the countries. When people are empowered financially they bridge the rift which creates social inequality creating a stable society Research has projected a perturbing trend that is arising due to the movement of people across the globe in pursuit of stability (Alan Philip, 2004). There is a looming prospect of demographic imbalances for instance the number of men going to the developed countries is increasingly high and this brings gender imbalance which may affects population growth and development. On the other hand there could be labor imbalance when all the young, educated and energetic young move to the developing countries laving the elderly who are unable to produce labor force in high magnitude A huge mass of the immigrants from the Middle East is siphoned to developing countries like The US, Europe, Japan, UAE and Canada. Most of the people hired from Middle East find place in the receiving countries in the production and transport sector a small percentage is normally absorbed in the technical and the professional field. The major challenge broaching the Middle East countries as far as migration and remittance are concerned is brain drain. A lot of the young people have been compelled to think that the only way they can make it in life is by moving to the developed countries, this they do at the peril o their developing countries. It’s unfortunate that the people who move out to the developed countries form the top cream of the developing countries and this deprives them of the profession al human resource. This challenge poses a perturbing dilemma to the developing countries because the graduates are siphoned out a lot of resource is wasted to bring up such individuals yet the countries don’t reap the anticipated benefits. When young people are brain drained the resources invested in them in order to attain education are wasted since they are never ploughed back into the economy. It must however be noted that the immigrants who leave their countries to pursue better opportunities in the developed countries also remit funds to their mother countries hence the loss is minimal. There is great fear that once young people get to put their attained skills into better use in destination countries. The developing countries cannot however blame young people for pursuing their professional careers in other countries because they have failed to offer the much needed job opportunities to the young vibrant generation. Conclusion There have been many arguments extended to gainsay the very trendy immigration drift which has been increasing at a spiraling spate. Critics have it that the trend causes brain drain and deprives the developing countries in Middle East of their best available human resources. Obviously, there are myriad issued accrued to this trend which raise a lot of concern; it must however, be noted that immigration and remittance play a massive role in filling in the gap where the developed countries have failed. Whilst, the developing countries have labor force they lack the mechanism and the market to assimilate them hence immigrations comes in hardy to solve the crisis offering jobs and foreign remittances. It can therefore be stated that both the receiving and the sending countries mutually benefit from this symbiotic kind of relation the only measure necessary is for the both groups to agree and set up a platform on which to operate so that non of the parties is exploited or misused in the trade. Ultimately the whole globe stands to befit from the advantages accrued to immigration and remittances in the international trade. References Angrist, J Adriana K. (2002).

The Business Environment in Relation to Morrisons Essay

The Business Environment in Relation to Morrisons - Essay Example The details further establish the salient use of the variables in rebuilding the supermarkets’ strategic framework. The company’s factors of success Morrisons has competently claimed its position in the U.Ks retail market through the lead in delivery of quality food and groceries. The supermarket chain has grown tremendously after merging with Safeways Company. Morrisons currently has the capability to make on-point deliveries effectively than the competitors. The outlet discovered that, some of its drawbacks resulted from poor distribution and delivery channels. Therefore, it strategized accordingly, and in the modern day, the company has a neat flow of goods to reach the final consumer via the outlets it established. The company has reduced the overall overheads through the procurement of privately owned transportation means, and outlets. The company enjoys customer loyalty through the delivery of quality goods satisfactorily at the time that the consumer may perceive the need (Henry, 2008: 66). Morrisons Company seeks to deliver value profitably to the consumer for mutual benefits. It first establishes customers’ needs and determines the most pressing that call for immediate attention. The company wins over the competition through intense research to ascertain any changes in the markets and the availability of new markets. Suppliers’ core value to a business is to deliver materials and inventories. Morrisons realized that, their suppliers were incompetent and the costs of sourcing them were relatively high. Therefore, the supermarket has established supply chains thus, resulting to reduced costs of materials and effective distribution of products to its various chain stores. The main factors towards the growth of supermarkets are; customer satisfaction, reduced costs hence considerably low prices, and effective delivery of quality products (Bensoussan & Fleisher, 2008: 68). The supermarket has continuously erected food stores in a n attempt to reach all entire market, which still remains inadequately catered for. Through the strategic mission and vision statements, the company propels the set plans and strategies to achieving its goals and objectives. Morrisons’ vision and mission statements express their practices inertly, and more emphasis relates to customer satisfaction. The company enjoys economies of scale by the fast and the effective rate of diversification of investment.  

The Relationship Between Social Class and Gender in Jane Eyre Essay

The Relationship Between Social Class and Gender in Jane Eyre - Essay Example Jane's father was a poor clergyman, on the fringes of middle class, and her mother in marrying him had lost the name and advantages of her own superior social standing, so they both lacked a well defined social status and the situation became worse as they left her an orphan. As Susan Fraiman says, both Jane's parents were "socially ambiguous, and this ambiguity is part of their legacy to Jane" (616). This ambiguous station in life leaves her open to statements like: "No; you are less than a servant, for you do nothing for your keep†. To this, the pressures of her gender add up, even the servants tend to sympathize with her less, because of her lack of good looks: â€Å""Yes," responded Abbot; "if she were a nice, pretty child, one might compassionate her forlornness; but one really cannot care for such a little toad as that." "Not a great deal, to be sure," agreed Bessie: "at any rate, a beauty like Miss Georgiana would be more moving in the same condition."† (Chapter 3) Jane is conscious of her social ambiguity and disadvantage in terms of femininity and its charms : â€Å"A Victorian woman's value resides chiefly in her femaleness† (Archibald, 8), and she seeks to overcome both through mental discipline in Lowood, where she does gain an education, only to become another socially ambiguous figure in Victorian England, a governess. This was the only respectable option open to a single woman without a family, or even money or connections enough to get suitably married

Investigating the Environmental Disaster in the Gulf of Mexico Essay

Investigating the Environmental Disaster in the Gulf of Mexico - Essay Example This has seriously impacted the human values of not causing harm to others. Thesis Statement: The purpose of this paper is to investigate the complexity and link between sustainability issues including natural laws and human values; and determine the ways in which human systems and ecosystems are linked. and the ethics of not causing harm (George 242). Moral law is a free will approach which gives people the freedom to decide the way in which they should act. â€Å"Moral law theory is morally absolute, not relativistic, connecting human nature and ethical life† (Houser et al 22). Ethical laws are natural, that is they apply to all human beings, irrespective of individual customs and beliefs. Significantly, natural laws are non-consequential, and the consequences of an act are not brought into the ethical analysis. In this respect, it is evident that the oil spill causing extensive destruction is the consequence of installing the particular oil rig, and this outcome is not included in the ethical analysis of the situation. According to natural law, human life has absolute value, hence a single life cannot be sacrificed to save several lives. Thus, it is in contrast with the utilitarian view of cost and benefit, and of achieving the greatest good for the greatest number of people (Houser et al 22). Additionally, natural law requires that moral judgments should take into account the intentions of the persons performing the act. In the oil rig disaster, it is not possible to make any moral judgment of right or wrong based on the intentions of the British Petroleum Company, since the occurrence of such a magnitude, which has caused extensive financial losses for the company was not deliberately intended to happen by them. However, the element of carelessness towards ensuring thorough safety in all aspects appears to have played a part in the catastrophe. The ongoing leakage from the oil well in the Gulf of Mexico, 48 miles

Structural Components Of Suspension Bridge Engineering Essay

Structural Components Of Suspension Bridge Engineering Essay INTRODUCTION Suspension bridge is a type of bridge in which the road way or the deck is suspended below the suspension cables. It is a simplest form of bridge which was made of rope and wood in olden days. The modern Suspension bridge developed was in 19th century. In those bridges the cables are carried by using vertical suspender. The two ends of the cables are suspended on towers. The weight of the bridge is transferred to the anchorage system by cables. The anchorage is fixed firmly on concrete blocks or solid rocks .In order to distribute the load evenly and also to protect the cables from breaking, the cables are spread over a large area inside the anchorage. Historical Background In early times human beings found it very difficult to cross the stream and a deep gorge to survive. A successful solution found out by early people was to drop a tree between the two banks of the deep flowing stream. This results in the idea of simple beam bridge in early times. Early bridges were made of post and lintel structures, stones or timber or the combination of the both. Later on the use of bamboo or simple rope gave rise to the development of rope suspension bridge. Central and South America and are the first to use rope suspension bridge. stock-photo-rope-bridge-suspension-bridge-35093119.jpg Figure:1 ROPE SUSPENSION BRIDGE Later on the chain cables were developed when the wrought iron bars became locally available. The first bridge constructed using chain cables were James Finleyà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s in Westmoreland country, Pennsylvania in 1801.In early British chain bridges the notable one was Menai bridge with 176m span. One of the longest parbolic arc chain was Clifton Suspension bridge. menai-bridge.jpg Figure :2 MENAI BRIDGE clifton-suspension-bridge-bristol-gben440.jpg Figure:3 CLIFTON SUSPENSION BRIDGE After the chain cable the wire-cable was developed. Foot à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬bridge at falls of Schuylkill was the first wire-cable suspension cable developed in 1861.The first major bridge constructed using modern methods was Joseph Chaley Grand Pont Suspendu across in Fribourg across the Sarine valley .Its construction was completed in 1834.The first major wire-cable in USA was the Wire à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬bridge at Fairmount in Philadelphia , Pennsylvania, span of 109m and the construction was completed during 1842. A notable bridge was Niagara bridge with250m span in 1855.Later on the American Engineers was constructing Suspension Bridge with higher span length. The notable one among them was are Ambassadar bridge in Detroit with 564m span in 1927, George Washington Bridge in New York with 1006m span in 1931 and Golden Gate Bridge in San Francisco in 1937.Among the parallel wire cables the Otto Beit bridge outside USA was the first Suspension bridge constructed with modern techniqu es. golden_gate.jpg Figure :4 GOLDEN GATE BRIDGE STRUCTURAL COMPONENTS OF SUSPENSION BRIDGE Figure 5 Structural Components of Suspension bridge The above figure shows the structural components of a three span Suspension bridge. The different parts of a suspension bridge are Main Cables which support the deck and transfer the loadings to the supporting tower and anchorages. Deck suspended from the main cables. Towers to support the main cables. Hangers which is used to connect main cables and deck Anchorages to which the ends of the main cables are connected to protect it against any movements. 1. CABLES The main function of cables is to support the deck which carries the traffic loadings and to transfer these traffic loadings to the towers and anchorages by direct tension forces. Cables are made of high strength steel wires. The tensile strength of the wire is 1550N/mm2. The cables of the Akashi Kaikyo bridge in Japan is made of wires having high strength with minimum tensile strength of 1800 N/mm2.The steel rods from which the wires are manufactured are having higher carbon content. The wire with high tensile strength is obtained by cold drawing the wire. After the final drawing the wire is galvanized for corrosion protection. 301678.jpg Figure 6 AKASHI KAIKYO BRIDGE Different types of cables a.Spiral Bridge Strands Spiral bridge strands are manufactured by winding several layer of round steel wires in a helical shape onto a straight centre core wire. When layers of wire are laid it should be made sure that an opposite helix to the preceding layer should be laid. Due to twisting of wires spiral strands gets self-compacted under axial loading. As a result of this when the strand is first loaded, non elastic stretch occurs. So in order that the strand should behave elastically, the twisting of wire should be avoided during manufacture. Examples of bridges that have used spiral bridge strand are Tancarville bridge (france) with span length 608m, Cable size is 56no, Diameter of strand is 72mm.Constuction was completed during 1959 Lillebaelt bridge (Denmark) with span length 600m, Cable size 55no, Diameter of strand is 68.7mm and 6no 41.4mm diameter strands. Construction was completed during 1969. Figure 7 Spiral bridge Strand b.Locked Coil Strand Locked coil strands is manufactured in the same way as the spiral strands is manufactured. The only difference between the two is that in locked coil strand the final layer of wires are made up of interlocking Z-shaped wires. As a result of this proportion of the cross sectional area of strand to wire area increases, also a smooth exterior surface is obtained .Examples of bridges that have used Locked coil strands are Tamar bridge (UK) with span length 335m cable size 31no, Diameter of strand is 60mm.Construction was completed during 1961. Rodenkirchan bridge (Germany) with span length 378m, Cable size 37no, Diameter of strand is 69mm.Construction was completed during 1954. Askay bridge (Norway) with span length 850m, Cables size 21no, Diameter of strand is 99mm.Construction is completed during 1993. There are two types of arrangements that can be provided for spiral strands and locked coil strands. One of them is close packed hexagonal formation which has the advantage that the cross-section can be circularized when aluminium or plastic spacer are added and then wrapped properly against corrosion. The other one is an open rectangular array which is rarely used and doesnot have any wrapping operation as in closed packed hexagonal formation. The cable bands are simple fabricated structure. The disadvantage of open rectangular array is that on increasing wind load on the cable it is difficult to conduct inspection and maintenance on the inner strands. c. Parallel wire cable In parallel wire cables, several individual wire over the whole cable length is laid straight and parallel. It is constructed in two ways, by aerial insitu spinning of the wires or by prefabricated parallel wire strands. Insitu span cables : The aerial spinning method was developed during the 19th century and it was mostly used in long span suspension bridge. In this method using the spinning wheel two or four loops of wire are pulled from one anchorage to the other. During each movement of the wheel, required sag is provided to the wire and the cables are assembled. Prefabricated parallel wire bands: In prefabricated parallel wire strands bundles of wires are bound together by keeping plastic tapes at intervals and are prefabricated into hexagonal shaped strands. At each end sockets are fitted. The Akashi kaikyo bridge was the first bridge to use the longest prefabricated parallel wire strands with 127 wire strands, with average strand length of 4073m. 2. DECK The main function of deck is to support the load. The deck is suspended on the main cables by using vertical hangers. The most important load that the deck has to carry is the traffic loadings. The self weight of deck should be low because the deck is carried by the cables. Stiffening girders should be provided in the deck to transfer the loads from the deck to hanger. 3.TOWERS The main function of tower is to support the main cable. The ends of the main cable is connected to the tower which at a sufficient height to provide cable sag. Tower also support the stiffening girder and side span. The initial loadings on the tower will be the vertical load acting at the top of the tower, applied by the main cables, together with the loads acting on cable and bridge deck due to wind load and load acting on stiffening girder. Flexible fixed base are provided for the tower and cable saddles are fixed on the top of the tower. Due to this type of arrangement any movement in the cable saddle due to varying load will result in the longitudinal bending of the tower legs 4.HANGERS The main function of hangers is to connect the bridge deck and stiffening girder to the main cables .Vertical hangers are used with equal intervals along the span. Based on using one or two parts of rope, there are two types of hangers. Two part hangers Two part hanger was used in long span suspension bridges. In this type of hanger the arrangement is in such way that over the main cables the hanger is drapped which is located in the groove of corresponding cable band. Using sockets the bottom ends of the two rope of the hanger are connected to the deck. Hangers are usually made of steel wire rope Single part hangers Single part hangers ends on the underneath of the cable and it is connected to the lower part of the corresponding cable band by a socket and pin connections. The lower end of the hanger is connected to the deck using simple bearing socket. This type of hanger is made up of spiral strand or parallel wires 5.ANCHORAGES The main function of anchorage is to support the ends of the main cable and to prevents any movements in the main cable by transferring the force from the main cable to the ground. Since the anchorage has to resist a large force the design of anchorages is very tough unless the ground on which the anchorage is to be positioned is good and also if sound rock is available in the ground. Avantages and Disadvantages of Suspension bridges Avantages 1.When compared to other bridges, higher spans can be provided for the main span in suspension bridge. 2. Construction cost can be reduced in Suspension bridge due to less material used when compared to other bridges 3. No access is required below during construction of suspension bridge when compared to other bridges. Only for the installation of initial temporary cables the access is required. 4.Suspension bridge can prevent earthquake movements than other bridges. 5. Suspension bridge can be constructed at heights above the waterways to allow the passage of tall ships. Disadvantage Bridge deck vibrating due to heavy wind is prevented using aerodynamic profiling. The deck stiffness of suspension bridge when compared to other bridges is very low. Due to this it makes the bridge very difficult to carry heavy rail traffic. The foundation work is costly and requires more area to combat the effect of heavy load on foundation towers ,when Suspension bridge is constructed on soft ground. NON LINEAR ANALYSIS OF SUSPENSION BRIDGE Suspension bridges was considered as the most efficient and remarkable in architectural appearance when compared to other structural systems. But suspension bridge has more tendency to get deformed due to the asymmetrical loadings. This kind of displacement is called as kinematical diaplacements. There are many ways to reduce the kinematical displacements in suspension bridges. One of the method is, if flexible cables are used in suspension bridges the local bending stiffness is taken into account while analyzing the stress-strain state. Other method to reduce kinematical displacement is to use rigid cables instead of flexible cables. Standard hot rolled or welded sections are used to make the structural elements. Also by using rigid cables it provides the required stiffness for the suspension bridge. The technique is not accurate but can be used or rough calculation. For analysing the suspension bridge made of flexible cables or rigid cables there are some numerical methods. The analysis of suspension bridge made of flexible cable is very difficult when the non-linear behavior is concerned. So it is analyzed based on the assumption that the main cables are made of flexible cables ,when only dead load is acting on the bridge its shape is parabola, all other structural elements are made of ideally elastic material, through out the span of the bridge the bending stiffness of the girder is assumed to be constant, the displacements in the hanger is neglected and the load acting on the cable is considered to be uniform. The loading is in such a way that dead load acts on the cable, the stiffening girder and cable supports the live load. By using these assumption the non-linear analysis is done using certain equations.But while analysisng suspension cables with rigid cables these assumptions are not applicable. In rigid cables there is always some bendi ng stiffness.Also the cables are made up of standard welded or steel sections for the suspension bridge to be initially a stabilized. Grigorjevaet al. (2006) proposed a technique for the analysis of suspension bridge with rigid cables. CASE STUDY Dynamic Response of the Suspension Span of the SAN FRANSICO-OAKLAND BAY BRIDGE The dynamic seismic analysis of the suspension span of San Fransico-Oakland bay bridge was modelled to make astudy on the effects on suspension bridge due to ground motions. Due to the combined effect of motions due to tectonic displacements and seismic waves ,ground motions are developed near-fault regions for along period. In olden days the seismic design codes for the structures were used based on the past experiences and the historical ground motion instrument and signal processing methods were not accurate.So it was very difficult to measure the ground motions. But the development of Modern broad-band, digital instruments helped in measuring the near-fault motions.The effect of long period motion is different for flexible and rigid structures. Rigid bodies will have a natural frequency higher than 0.2Hz and for longer wavelength seismic waves it behaves as a rigid body. But for flexible bodies the natural frequency will be low. Using a finite-element modeling software the structure is modeled.The deck model is a combination of truss,membrane and sway stiffness elements.The steel braced tower is represented by fibre bending elements and the bridge cable is represented by tension-only cable element.The advantage of modelling the structure in this way helps to reduce the degree of freedom which is an essential aspect in the repose of suspension bridge. After the gravity initialization is completed as described in detil by McCallen and Astaneh,2000 ,the explicit integration scheme for non-linear analysis of earthquake motion is done. The ground motions in the near by areas will be affected by various reasons like the superposition of seismic waves, site geological response etc. The effect of these parameters may vary for different ruptures happening in future and these rupture may cause changes displacement in ground, velocities and accelarations. In this study the effect of rupture and wave propagation were studied by providing a parallel and finite difference in computational simulation of the rupture,a three dimensional finite difference calculation, empirical Green function and at seven points in San Fransico-Oakland Bay Bridge the ground motion is computed. By doing the above said it was found out that the far field in the near source can result in fault with periods of 0.2 to 0.5s due to directivity effects and the near field arrivals can result in fault with periods of 0.2 to 0.1 s due to tectonic movements. There are chances for these long period arrivals to accur along with the future earthquakes along the Hayward or San Andreas faults which is nearby San Franciso-Oakland bay Bridge and it will affect the long span bridges in San Fransico bridge. Along the Hayward fault ,five locations along the suspension span of western San Fransico two rupture model were synthesized for a ground motion of Mw =7.25.These were consid ered as mean and other one as standard deviation models.They were represented as HAY06 and HAY31.The ground displacements at the bridge generated was greater for the mean fault than the standard deviation but the standard deviation produced more acceleration and long durations.Analysis of the model has shown that the mean model produced more stress than the standard deviation. The response of Bay bridge is computed against the ground motion from the rupture model HAY06.Due to this displacements occur which indicates that the flexible deck cannot respond as fast as the towers when large displacement occurs. The tower motion lags and then the deck starts to respond when the tower returns with the ground.

Diabetes :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Since diabetes is such a complex disease with many different forms, I decided to focus on diabetes type I. This is known as insulin-dependent diabetes mellitus (IDDM). This type of diabetes includes people who are dependant on injections of insulin on a daily basis in order to satisfy the bodies insulin needs, they cannot survive without these injections.   Ã‚  Ã‚  Ã‚  Ã‚  In order to understand the disease you need to know about insulin. Insulin is a hormone. The role of insulin is to convert the food we eat into various useful substances, discarding everything that is wasteful.   Ã‚  Ã‚  Ã‚  Ã‚  It is the job of insulin to see that the useful substances are put to best use for our well-being. The useful substances are used for building cells, are made ready for immediate expenditure as energy and also stored for later energy expenditure. Insulin comes from the beta cells which are located in the pancreas. In the case of diabetes type I almost all of the beta cells have been destroyed. Therefore daily injections of insulin become essential to life.   Ã‚  Ã‚  Ã‚  Ã‚  The cause of diabetes is an absolute or lack of the hormone insulin. As a result of this lack of insulin the processes that involve converting the foods we eat into various useful substances does not occur.   Ã‚  Ã‚  Ã‚  Ã‚  One of the products that is of vital importance in our bodies is glucose, a simple carbohydrate sugar which is needed by virtually every part of our body as fuel to function.   Ã‚  Ã‚  Ã‚  Ã‚  Insulin controls the amount of glucose distributed to vital organs and also the muscles. In diabetics due to the lack of insulin and therefore the control of glucose given to different body parts they face death if they don't inject themselves with insulin daily.   Ã‚  Ã‚  Ã‚  Ã‚  Since strict monitoring of diabetes is needed for the control of the disease, little room is left for carelessness. As a result, diabetic patients are susceptible to many other diseases and ser-ious conditions if a proper course of treatment is not followed.   Ã‚  Ã‚  Ã‚  Ã‚  Other diseases a diabetic is open to: Cardiovascular disease, stroke, Peripheral artery disease, gangrene, kidney disease, blindness, hypertension, nerve damage, impotence etc.
