CRIME AND SOCIAL HISTORY - Essay Example Since vigilantism has its focus on the control of crime and other social standards, its manifestation is likely to occur in atmospheres rife with crime problems and social inequities (Dumsday 2009, p. 50). When the public watches as their government fails to sufficiently uphold the values and norms it was designed to protect, they are likely to engage in acts of vigilantism (Dumsday 2009, p. 50). The vigilante group form and function because they understand that some established rules are threatened or could possibly be threatened and transgressed (Dumsday 2009, p. 55). Vigilantism also surfaces after a period of organization, rather than by spontaneous eruption (Dumsday 2009, p. 50). South African vigilantism reflects these descriptions. As Buur (2006) describes, South African vigilantism arose in response to the failure of formal law (p. 735). Paradoxically, the one element the vigilantism was primarily responding to was crime (Buur 2006, p. 736). The public’s view of the law enforcement capabilities of their government was very poor, and so they lacked confidence in the accepted and institutionalized norms. In South Africa, a long history of vigilantism exists, including the formation there of a group of vigilantes that rose up to fight a group of hijackers that wore police uniforms in order to more effectively accomplish their goals (Buur 2006, p. 741). The Irish Republican Army (IRA) organized itself to carry out vigilantism in response to British occupation of Northern Ireland (Pruitt 2007, p. 1521). The people resented British presence there for many years, but didn’t organize vigilantism until 1968, after four decades of tension had built (Pruitt 2007, p. 1521). The people of Ireland who shared this common goal of eliminating British rule and reuniting Northern Ireland with the rest of the country organized at nonviolent demonstrations at that time (Pruitt 2007, p. 1521). When the police responded violently to the demonstrations, chaos ensued

Global and regional environmental Essay Example for Free

Global and regional environmental Essay People across the globe are being affected by global and regional environmental changes. The drastic environmental problems such ozone layer depletion and climate change are as a result of over consumption, unsustainable life styles and unhealthy patterns of development (Harris, 47). Environmental problems are likely to hit the marginalized and the poor first often with drastic consequences but latter they will also affect the privileged. Unless these environmental problems are curbed they are threatening to cause havoc to the life support systems and the ecosystems. This will therefore lead to an immense and unprecedented crisis for the whole humanity. To achieve sustainable development and the health of the environment it requires drastic changes in the current global order and formulation of the alternative ways of thinking. Within environmental movements there are huge wealth of experiences, ideas and visions of what an alternative environmental sustainable and people oriented societies can look like. Environmental destruction has always been part of the human history (Harris, 48). Throughout time the problems of the environment have been important factors affecting the health of people both at regional and global level. The pressure on the environment has increased enormously as a result of changing scales of the human society increases and development of the technology. This problem is fuelled by the runaway global economic systems which have created over consumption (unprecedented affluence) and enormous level of poverty. The environmental problems now threaten to cause irreversible harm to the ecosystems and increase inequalities on a global scale (Pickering Owen, 117). Some of the environmental problems are immediate local problems whose their causes can be known and their solutions be identified. On the other hand other environmental problems are incredibly complex and they are often complex to handle. Such environmental problems involve much uncertainty and affect the whole globe and are the result of combined human behavior. These problems are maintained and embedded on the societal structures (Harris, 50). Some critics argue that environmental problems are as a result of the present day population growth especially in the third world countries and natural resources depletion in the highly industrialized countries (Harris, 50). Alarmist argue that the explosive population growth in less developed countries and overexploitation of the non renewable resources by the highly industrialized countries are combining to produce sets of condition which cannot be sustained in the long-run by our finite world. The population problems of third world countries constitute an impediment to social economic development and can pose a threat to depletion of natural resources. However relatively low crude population densities in many third world countries with exception of some few areas they do not produce population pressure on the natural resources (Harris, 52). Most of the third worlds countries have an even population distribution and few urban centers are becoming overcrowded. High rates of population growth in third world countries is as a result of high and constant fertility that have possibilities of reducing mortality due to the improved health facilities. Because of high proportion of children and high patterns of fertility heavy dependence burden is produced within the populations in most third world countries. The heavy dependence implies large expenditures of provision of employment and education for the growing population (Pickering Owen, 134). Most bureaucrats, economists and political leaders in third world countries especially in Africa argue that third world countries in Africa have abundant resources which have not yet been tapped. They also argue that large area in Africa have not been inhabited and therefore the political question that population growth put pressure on the limited natural resources should not be taken seriously (Harris, 53). There is need for the political leaders, economist and bureaucrats to know the prospect of the third world countries in terms of the resources base that can absorb the population problems of the third world countries (Harris, 54). In comparison to other industrialized countries for example Europe nations the land under cultivation in third world African countries is three times higher per capita, the livestock per capita is two times higher, the grazing land per each unit of livestock is a bout seven times higher while the mineral resources out put of third worlds countries in Africa constitute one tenth of the mineral output of the whole world (Harris, 54). The primary energy resources of the third world countries are enormous which are comprised of natural gas and petroleum product coal and hydro power for example 32 percent of world hydro power which can be exploited, 12 percent of reserves of uranium and 60 percent of thorium reserves are found in Africa third world countries. Despite the abundant resources of the third world countries most countries in Africa are under developed (Harris, 57). It would be a weak argument to suggest that the high population growth in the third world countries is the root cause of their underdevelopment. However the high population growth of the third world countries is an important factor that impedes development. The rapid population growth constitutes pressure on the arable land. Several million hectares of land are being degraded in third world countries (Pickering Owen, 204). The degradation of land can be linked to population pressure and poverty, values and attitude of people weak tenure systems and land management and drought which often results in over exploitation of the natural resources such as the trees used for fuel wood, overgrazing deforestation and unsustainable agricultural activities. Degradation has decreased land productivity, increased desertification and causes loss of arable land in most third world countries (Pickering Owen, 206). As a result of degradation in the third world countries there is less food than can be produced in degraded lands and also the availability of biomass is greatly reduced. Land degradation also makes the ecosystems to be less resilient and increases chances of malnutrition and susceptibility of diseases in the local populations. Third world countries like china, Ethiopia, Brazil, Nepal, India and most African countries have caused much of environmental degradation. In recent time the respective government has began to introduce policies to minimize the extensive environmental degradation that their countries are facing (Pickering Owen, 213). The environmental policies have been developed soon after formation of and applying pressure by several activist groups in the field of environment. Initially before the activist groups applied pressure the governments in the third world countries did not see any needs to develop environmental policies. Environmental degradation is only the problem of the third world countries and most often thirds world countries have make do with what they owns and usually they compete with large populations (Pickering Owen, 208). Once a natural resource for example water is degraded it become of little use to the people. On the other hand western or industrialized countries have a higher standard of living than third world countries or less developed countries. In developed countries the communities have access to electricity, clean water, housing, employment, refrigeration, clothing, food, heating, hospital, schools, medicines, machinery, manufacturing, communication and road thus in the process they consume much of the resources (Pickering Owen, 209). The communities of the third world poor countries do not have access to these things and they rely on what they can hunt, gather or grow. People in the third world countries acquire other things if they have surplus produce to sell and therefore are disadvantaged to gain access to power supply, telecommunication, railways and roads thus becomes difficult to access the few schools hospitals etc and therefore third world countries are not degrading the environment as much as the developed nations (Pickering Owen, 210).

The Recent Negative Effect Of Technology On Society Essay example -- e

The Recent Negative Effect of Technology on Society   Ã‚  Ã‚  Ã‚  Ã‚  Ever since the Industrial revolution, technology has been changing at a fast pace. People are always wanting a better lifestyle therefore there is always something new arising so humans can cope with their physical environment. One of the most important breakthroughs for technology was the agricultural system. The agricultural system was the basis for the technology of the future. The agricultural system brought on the need for transportation, workers and even, battles over land. The need for transportation brought vehicles into the market. The need for employees brought mechanical robots into society. Battles over land brought on the need for sophisticated weapons. The agricultural system brought on a revolution. The invention of the television can bring media and other forms of entertainment into your house with video and audio combined. Before 1950, newspapers and radio were the only ways to bring media or entertainment into the house. Mass production and other job opportunities brought many people from the suburbs and farms into the city. We can now have forms of electricity directed into our houses for heating and light. Humans are more reliant on technology then ever before. All of these technological advances sound great, however, there is a negative effect to all this technology. Technology can serve to actually harm humans rather then help them. Competition between companies or even cities can sometimes make lives for humans even worse. Take for example when a city builds better and more roads to attract tourists. This actually creates more traffic, not less. Technology also changes our sense of common purpose. New inventions such as the personal computer and machines can change our lifestyles. Even things we take for granted such as the automobile have negative effects on technology. The oil needed for a car to run needs to be imported and sometimes accidents such as the Exxon Valdez incident spills many gallons of oil into the ocean. All of these examples show how technology has negative effects on society.   Ã‚  Ã‚  Ã‚  Ã‚  First, competition can lead to a negative effect of technology. When a company in the U.S. produces shoes and a company in Great Britain produces shoes as well, they must fight for their market share... ...n conclusion, society has recently seen the negative effects of society. Competition between cities and companies has taken away jobs and brought unwanted and costly projects into pleasurable areas. A change in lifestyle among almost every human being is yet another negative effect of technology. What has happened to people since supermarkets came to town? People do not want to hunt for food anymore. They find it much easier to walk into a store and purchase it. A third reason why technology has a negative effect on society is the advent of highly reliant possessions such as the automobile. Many people count on traveling to work everyday by car. If the car was somehow taken away from people then there would be chaos. It is much too late to take it away. Humans are much too reliant on it. There is not enough mass transit to transport all of the present car users. Hopefully, future technologies will be fully considered. We must look at the advantages and consequences and measure if society will benefit or suffer from the technology. Past technologies weren't fully considered and if they were, there is a chance that the automobile never would have went into production.

Groups Opposing Active Euthanasia For Robert Wendland :: Euthanasia Physician Assisted Suicide

Groups Opposing Active Euthanasia For Robert Wendland On September 29, 1993, Robert Wendland, then age 42, was involved in a vehicle accident. He was in a coma for 16 months. In January 1995, Mr. Wendland came out of the coma, but he remains severely cognitively impaired. He is paralyzed on the right side. He communicates using a "Yes/No" communication board. He receives food and fluids through a feeding tube. During rehabilitation, he has been able to do such activities as grasp and release a ball, operate an electric wheelchair with a joystick, move himself in a manual wheelchair with his left hand or foot, balance himself momentarily in a "standing frame" while grabbing and pulling "thera-putty," draw the letter "R," and choose and replace requested color blocks out of several color choices. The Probate Court appointed Robert Wendland's wife, Rose, as conservator of his person under the Probate Code. Rose sought authorization from the court to remove the feeding tube, thereby starving him to death. Robert's mother (Florence Wendland) and sister (Rebekah Vinson) objected. Various groups opposed to active euthanasia became involved in the case with amicus briefs: Not Dead Yet is a national grassroots organization of people with disabilities formed in response to the increasing popularity of, and laws permitting, physician assisted suicide and euthanasia in the United States and around the world. Not Dead Yet's mission is to advocate against legalization of physician assisted suicide and euthanasia, and to bring a disability-rights perspective and awareness of the effects of discrimination to the legal and sociological debate around euthanasia and physician assisted suicide. Formed in 1996 in Illinois, Not Dead Yet has worked to educate, support, coordinate and lead the disability community's effort to stop the "right to die" from becoming a duty to die or a right to kill. While it is impossible to determine how many people with disabilities, family members and allies, call themselves members of Not Dead Yet, members have undertaken specific activities in the name of the organization and in support of its mission in at least 30 states. Not Dea d Yet has given invited testimony before the U.S. Congress three times, once before the U.S. Senate Judiciary Committee and twice before the Constitution Subcommittee of the U.S. House of Representatives. When Not Dead Yet members attended the long awaited 1999 trial of Jack Kevorkian (the first after three years of non-prosecution, and scores of assisted suicides of people with non-terminal disabilities) and silently demanded the equal protection of the law, he was convicted.

Reservation Blues Essay

Sherman Alexie, author of the novel Reservation Blues, explains that at the start of an Indian’s life on a reservation, he or she is destined to be hopeless. First, parental guidance is infrequent leaving many infant Indians with an insufficient childhood. After that, Indian children experience poor education revolved around heaps of stereotyping and bullying from their white classmates and teachers. Next, any sort of entertainment such as television, music, and books are extremely rare. Then leaving their life with a lack of stability and sustainability, an Indian grows up on a reservation with little to no job opportunity. On top of that, reservations are subjected to commodity food; food hardly sufficient and plentiful enough to satisfy a human’s basic needs. All of these factors fill the lives on the reservation with despair, causing most Indians to indulge in alcohol, violence, and suicide. And so, hopelessness within modern Native Americans ultimately leads to sel f destructive behavior. Hopelessness eludes few Indians on the Spokanes Reservations, and Samuel Build-The-Fire profoundly exemplifies lost hope. Alexie asserts that when Builds-The-Fires was young, he was named Player of the Year and was interviewed by Walter Cronkite because of his significant basketball talent. Samuel became a hero because of his success, and his fellow tribe members wanted him to become more than just an average Indian on the reservation. Until, that is, Alexie describes that after a crooked basketball game with the Reservation’s white policeman, Samuel’s basketball ability was lost. This loss in Samuel’s life created a void, leaving him empty. After dragging his old, drunken, helpless father in from the lawn outside, Builds-The-Fire’s son, Thomas expresses that â€Å"His basketball days [are] over, he [doesn’t] have much else.† Finally, Samuel’s destructive behavior of being an alcoholic and a constant public disturbance articulates that he has no hope in life. Victor’s life reveals a life without family, education and income. Alexie explains that Victor watching his dead mother being stuffed into a trunk by his step-father invokes the start of Victor’s hopeless life. This depicts the sort of troubled life Victor has lived. The only spawn of hope Victor formulates is within his friendship with Junior; however, that hope soon dies as Alexie reveals that Junior committed suicide. In being too inept to  obtain a job due to his lack of education, Victor maintains a full-time career in being a hopeless drunk just like Samuel Builds-The-Fire. Alexie suggests nothing else is left for Victor to do in life except to be destructive. Alexie elucidates that Junior failed at being successful at life outside of the reservation and could not handle living with his failure so he committed suicide. In being one of the intelligent Indians on the Reservation, Junior sought a college education. Junior had hope that he could escape life on the Reservation. Nevertheless, he dropped out of college and fell in love with a white-woman named Lynn. Alexie discloses that Junior got Lynn pregnant and she rejected Junior as a suitable life partner and father to her child because Junior was Indian. These series of events made Junior feel not only very forlorn in general, but also ashamed to be an Indian. Alexie then conveys that Liz’s abortion of the baby evokes suicidal thoughts within Junior. In the end, Junior becomes so distraught with what has become of his life that he kills himself. The modern Native American has a life where there is no hope and a great amount of self destruction. Samuel, Victor, and Junior all had things that supplied them with some sort of hope. Samuel had basketball, Victor had Junior, and Junior had his own intelligence, but in the end each individual lost their source of hope. Alexie’s writing is a rare and honest interpretation of the many different factors and issues the modern Indian comes to terms with during the course of their life. The lack of hope within Native American Reservations is just one of many tribulations faced, but it produces some of the most self-destructive results.

Testing Your Perl Installation

Testing Your Perl Installation In order to test our fresh installation of Perl, well need a simple Perl program. The first thing most new programmers learn is how to make the script say Hello World. Lets look at a simple Perl script that does just that. #!/usr/bin/perl print Hello World.\n; The first line is there to tell the computer where the Perl interpreter is located. Perl is an interpreted language, which means that rather than compiling our programs, we use the Perl interpreter to run them. This first line is usually #!/usr/bin/perl or #!/usr/local/bin/perl, but depends on how Perl was installed on your system. The second line tells the Perl interpreter to print the words Hello World. followed by a newline (a carriage return). If our Perl installation is working correctly, then when we run the program, we should see the following output: Hello World. Testing your Perl installation is different depending on the type of system you are using, but well take a look at the two most common situations: Testing Perl on Windows  (ActivePerl)Testing Perl on *nix Systems The first thing youll want to do is make sure youve followed the  ActivePerl Installation tutorial  and installed ActivePerl and the Perl Package Manager on your machine. Next, create a folder on your C: drive to store your scripts in for the sake of the tutorial, well call this folder  perlscripts. Copy the Hello World program into C:\perlscripts\ and make sure the filename is  hello.pl. Getting a Windows Command Prompt Now we need to get to a Windows command prompt. Do this by clicking on the  Start  menu and selecting the item  Run.... This will pop up the run screen that contains the  Open:  line. From here, just type  cmd  into the  Open:  field and press the  Enter  key. This will open (yet another) window which is our Windows command prompt. You should see something like this: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:\Documents and Settings\perlguide\Desktop We need to change to the directory (cd) that contains our Perl scripts by typing in the following command: cd c:\perlscripts That should make our prompt reflect the change in the path like so: C:\perlscripts Now that were in the same directory as the script, we can run it simply by typing its name at the command prompt: hello.pl If Perl is installed and running correctly, it should output the phrase Hello World., and then return you to the Windows command prompt. An alternate method of testing your Perl installation is by running the interpreter itself with the  -v  flag: perl -v If the Perl interpreter is working correctly, this should output quite a bit of information, including the current version of Perl you are running. Testing Your Installation If you are using a school or work Unix / Linux server, chances are Perl is already installed and running when in doubt, just ask your system administrator or technical staff. There are a few ways we can test our installation, but first, you will need to complete two preliminary steps.​ First, you must copy your Hello World program to your home directory. This is usually accomplished via FTP.   Once your script has been copied to your server, you will need to get to a  shell prompt  on the machine, usually via SSH. When you have reached the command prompt, you can change into your  home  directory by typing the following command: cd ~ Once there, testing your Perl installation is very similar to testing on a windows system with one extra step. In order to  execute  the program, you must first tell the operating system that the file is OK to execute. This is done by setting the permissions on the script so that anyone can execute it. You can do this by using the  chmod  command: chmod 755 hello.pl Once youve set the permissions, you can then execute the script by simply typing its name. hello.pl If that doesnt work, you might not have your home directory in your current path. As long as you are in the same directory as the script, you can tell the operating system to run the program (in the current directory) like so: ./hello.pl If Perl is installed and running correctly, it should output the phrase Hello World., and then return you to the Windows command prompt. An alternate method of testing your Perl installation is by running the interpreter itself with the  -v  flag: perl -v If the Perl interpreter is working correctly, this should output quite a bit of information, including the current version of Perl you are running.

Coming to the New World essays

Coming to the New World essays Coming to the New World was a major advancement in the lives of many Spanish, French, and English people between the years of 1942-1629. The migration effected the lives dramatically. They will come to see that in the coming years almost everything will change from religion to their types of settlement. The role of religion was very important, for it had an immense power over the European society. Christianity converted all of Europe including the Spanish, French, and English. Christian doctrine provided a common understanding of God. The church provided authority and discipline in the society. Every village had a church, which thought that Satan constantly challenged God by tempting people into evil. Christianity had played an important role in Portugal and Spain, but it divided Europe into Catholics and Protestants. A protestant rebellion in the Spanish Netherlands drained the wealth of the Spanish and gave resources to expand into North America and brought a new impact of European and Indian people. Over time, the Catholic Church had become very large and wealthy, controlling resources throughout Europe. In 1517, a German monk and professor, Martin Luther, sold indulgences. These were church certificates that pardoned a sinner from punishments in the afterlife. He was excommunicauhujuujjujjted by the pope and threatened with punishment by King Charles I of Spain. He was protected by a northern German princess and could not be arrested. After Luther, came a French theologian from Switzerland named John Calvin. He stressed omnipotence of God and the corruption of human nature. He preached the doctrine of predestination, the idea that God chose certain people for salvation even before they were born. He appeared to Christians and said to people that they needed a personal relationship with God. Calvin believed in a God that gave what he received and also that saintly people could change government. People starte...

Elies loss of faith

Night, by Elie Weisel/ Elies loss of faith Free Online Research Papers â€Å"Night† tells a horrific story of the terrifying concentration camp that many people were imprisoned in. Throughout the story the author and many other people had lost their faith in God. There are many examples showing people trying to strengthen their belief in god but afterward there was much more examples showing people rebelling against god and forgetting their religion. Wiesel wasnt always so doubtful of his god but after his life changing experience he started questioning this idea of god. Before concentration camp he was an avid learner and was even searching for a teacher in order to teach him more about his faith. Later he sees what the concentration camp is doing to his people. When a prisoner tells Elies father that they are on their way to the crematory Elie questions god. â€Å"Why should I bless His name? The Eternal, lord of the Universe, the All-Powerful and Terrible, was silent. What had I to thank Him for?† (Wiesel 31). Elie thinks of his god as a person that would protect his own people but after seeing so many of his own people killed for no reason his faith was deminishing. Elie is losing his faith in god day by day and every time he sees another person get killed. He does not under stand why this is happening and if there is a god, then why is he allowing this to happen. When Elie saw children being dumped into a fire he thought to himself â€Å"Never shall I forget those flames which consumed my faith forever Never shall I forget these moments which murdered my God and my soul and turned my dreams to dust.Never.†(Wiesel 32). As Elie watch those innocent children get burned, his feelings for god were burning away at the same time. In the end Elie has lost his trust and love for god and finds out he is alone in this cruel world. â€Å"This day I ceased to plead.My eyes were open and I was alone-terribly alone in a world without God and without man.I ceased to be anything but ashes, yet I felt myself to be more powerful than the Almighty, to whom my life had been tied to for so long.†(Wiesel 65). After all he has seen throughout the camp he discovers that god is not there to help him or watch over him. Elie was a very dedicated student and wanted to learn all about the Kabbalah. Then later him and his people were shipped off to a camp to be killed. He saw all sorts of horrific things, he saw children die, people starved, people tortured, and people robbed of their faith. Even though Elies faith has been through so much battering, a small portion of him thinks that a god exist â€Å"And in spite of myself,a prayer formed inside of me, a prayer to this God in whom I no longer believed†(Wiesel 91). Although Elie is indeed performing a real prayer to his former god I think that he is just desperate and nothing can help him besides a almighty god. Throughout the story there were people who hung onto their god under horrific circumstance and some people who gave up on god at the first test of loyalty. Night is a very powerful book; you can see how and when the character loses his faith and you can understand why.

A History of Nazi Germany Essay Example | Topics and Well Written Essays - 1250 words

A History of Nazi Germany - Essay Example The German economy was greatly hindered as Germany, after the First World War, was taking the complete responsibility of the financial loss, the lives that were lost and mass destruction, this brought down the whole country.The German soldiers turned to fascism as they were unable to the proper supplies for their survival after their return from war. Germany could not get any help to recover from their financial loss, after the First World War the whole world went into great depression this too was not of any help to the German economy. As a result the country turned to fascism to get its wealth and pride back.Adolf Hitler, the political leader of the National Socialist German Workers, was one of the main personalities who promoted the fascist ideas. Hitler was assisted in promoting this Nazi concept by Albert Speer. Hitler was supported by the Germans and they turned to his ideas as he promised to meet their monetary needs after the world war I. The offer made by Hitler was irresist ible by the Germans and they declared him the Chancellor of their country.Hitler's government was fascist in nature which was led by dictatorship, and the dictator had absolute power, he suppressed other political parties, had control over the financial affairs and the dictator was considered to be a strong nationalist. The complete order and control of the German Government was in Hitler's hands through this philosophy. Hitler through his personal guard the SS, enforced fascism and his government hated particular groups of people and also was very racial. Hitler joined a group called the German Workers Party in the year 1919 in the city of Munich. Within no time he became one of the seven committee members who headed the party. This party held meetings in which different issues like the threat posed by the enemy namely the Bolshevisks that is the Communists who had come to power in Russia, the areas where the present government lacked, the weakness of the government and the threat posed by the Jews who were the enemies within the country were brought forth. They also spoke about the better times before the first world war. "In March 1920 he was discharged from the army and became a professional politician. His meteoric rise had begun." 1 Hitler began operations in forming his new political party, it was renamed as the National Socialist German Worker's party which is in short the Nazi party. the party won around eight hundred thousand votes, however it was more than just a political party. it was being turned into a military force by their leader Adolf Hitler. A group called the "Storm troopers" were trained by him to act as militia at his command. The Nazi party and its troops were being supported by the past German military leaders. In Bavaria in the beginning the Nazi party was formed and started out as a small group called the German Worker's party. The party was resisted and opposed to the Treaty of Versailles and Communism. the party came to existence and was formed by the Germans due to the humiliation they faced as they a result of their defeat in the First World War and the severe terms and regulations imposed on them by the Allies. At first Hitler joined this party as a secret agent and later became one of the most influential members of the party, as a result of his power to inspire and enthusiasm for the cause he became the leader of this small party, influencing and promoting his ideas to the people of similar ideology. 1. Carsten, Francis Ludwig, 1967. The Rise of Facism. (University of California Press: USA, 1967), 95. This party was soon renamed as the National and Socialist German Workers Party, their political manifesto was based on a twenty five point program that was adopted by the party. it was due to their strength of their belief in the twenty five points that the Nazi's chose to take force in Munich in a coup d' etat. Despite an initial success in achieving the coup's main objective of seizing power, the coup was unsuccessful. The party seemed to be destroyed and Hitler was

SPSS-Analysis Assignment Example | Topics and Well Written Essays - 1000 words

SPSS-Analysis - Assignment Example This assignment describes the E-commerce topic that is a growing trend in the current business field. For this reasons, persons operating within the business industry should take a keen interest in the behaviors of consumers operating within the e-commerce business segment. To gain a better understanding, the researcher reviews previous literature on this subject and understands the various gaps and strengths that we can utilize to conduct future research. In this regard, this assignment discusses in detail two notable quantitative research analysis methods that have been employed in previous research and could potentially be useful for future studies in the area of e-commerce. The two research methods that we will be looking at are Partial least squares path modeling (PLS-SEM) and exploratory factor analysis (EFA). The first method, PLS-SEM, was utilized in the research article â€Å"Influences of gender and product type on online purchasing†. The second method EFA was utiliz ed in the research â€Å"Customer loyalty in e-commerce: an exploration of its antecedents and consequences†. After review the analysis and results of both articles, it is conclusive that the researchers were keen on the expected data analysis section of their chosen methods. An EFA analyses and their results are clear and easily understood by the audience. As for Pascual-Miguel, Agudo-Peregrina, and Chaparro-Pelà ¡ez , they had to modify a section of the data analyses for it to fit their collected data and the end results were satisfactory.

Differences between Qualitative and Quantitative studies Coursework

Differences between Qualitative and Quantitative studies - Coursework Example Qualitative study focuses more on getting detailed information about the subject whereas quantitative study focuses more on gathering data using large-scale surveys. Interviewing a focus group is one of the best examples of a qualitative study in which researchers interview a group and identify the thoughts and perceptions of that group. DiCicco-Bloom and Crabtree (2006) states, â€Å"Interviews are among the most familiar strategies for collecting qualitative data†. In qualitative studies, researchers make use of different data collecting techniques to explore attitudes and behaviors of people whereas in quantitative research, researchers use structured research instruments like large-scale surveys to know what people think about the research topic. In qualitative studies, researchers collect data using interviews, group discussions, and task oriented observations whereas in quantitative studies, the methods used for collecting data include observing large groups and surveyin g specific types of individuals. Therefore, we can say that there are more techniques available in qualitative studies for data development as compared to the techniques available in quantitative studies. Relationship with the Research  Researchers doing qualitative study are not much aware of the details that makes them interact personally with people to gather information related to different aspects of the research. For example, to get information regarding effects of diabetes on a person’s health, the researchers need to interact.

The main points of focus are the ability of computer systems to operate effectively when employed on relevant scenarios. The evident exposition here is the failure of the specified projects. Their failures have been attributed to by several issues ranging from technology to management and both. Moreover the National Audit Office has a number of stipulations in its desire for elimination of central government wastage or overspending and improvement of success rates of the projects (Liebowitz & Khosrowpour 2007). In the past, the government has succumbed significantly due to the consequences of unproductive plans that have been deficient of the ability to progress. Considering their progressions, it implies that the projects might have not been capable of delivering as per the expectations of their initial aims (Khosrowpour 2006). Similarly, the inabi lity to succeed might also lie on the projects tendency of accruing losses. In this case the latter is more significant for considerations since both of the selected case studies have the basic facet. The case studies selected for analysis are the independent learning accounts and the pathway. Comprehensively, the independent learning accounts incorporate a scenario that led to the loss of ?97 million whilst the pathway associated a loss of 1 billion Euros. In this instance, the citation convinces the logic of seeking an appropriate means of curbing the situation that might transpire into such losses both presently and in the future (Liebowitz & Khosrowpour 2007). The Independent Learning Accounts Let us assess the specific instances of the projects. First, the independent learning accounts and as a government project. This was the 2001 system offering adults ?150 for educational use was abandoned after fraudsters coined millions in fake applications. The independent learning accoun ts were a system designed to offer adults funds for educational reasons (Schwalbe 2010). In this case, the system failed when the fraudsters succeeded in compromising its effectiveness and obtain benefits from it leading to the government loss. However, this project was chosen since it involves the loss of money from external fraudsters who depends on their skills for malicious gains (NAO 2012). This is the main point for the projects preference since it outlines the major point of scenario that the fraudsters use currently in obtaining benefits they do not merit from genuine projects. This problem is rampant virtually in all situation organizations and by attaining its remedy would assist in resolving other related problems in other scenarios. Management Issues Concerning the management issues leading to the failure of projects, there was poor testing in the case of independent learning accounts project. It is imperative to understand that the project developers and the experts per form series of testing processes of the project (Khosrowpour 1999). The tests are aimed at determining the flaws and formulating technical means of curbing them. In this case technology is the main consideration and the security of a system is imperative for contemplation. According to Madeley (1991), security has to be tested in all perspectives because the system is conveyed via the network and usually users would try the effectiveness of the system as well as detection and blockage of security

Describe the key stages of budgetary process, (b) Critically evaluate, Essay

Describe the key stages of budgetary process, (b) Critically evaluate, referring to the research findings the social significance of budgeting in modern organisations - Essay Example Budgeting process can be done for several reasons in an organization like planning, communication, coordination, motivation, performance evaluation and controlling process. Budgets can be of various types like short term budgets which are done for a month, a quarter or for a year. Operational control budgets are mainly done for a specific operation and the duration of this type of budget is a week or maximum a month. The most long term budget is known as capital budget which is done by the company for a period of more than one year and it can be extended to ten years and it determines that whether a company should proceed for a long term investment or not . Budgets can also be differentiated as sales budget which estimates the amount of future sales revenue and create a target for sales, production budget which estimates the number of output that should be produced to meet they sales target. Marketing budgets help to estimate the amount which is necessary for advertising and promotio nal activities to place the product in the market (Collier, 2002, pp. 207-208). Budgets are mainly based on the standard costing method for a certain level of production and sales. It should be prepared by an experienced accountant. A budget should describe the objective of the budget and the steps that are involved in the process of budget. There are several steps involved in the budgeting process which area s follows- Communication about the guidelines and policies with those people who making the budget is very important because e many decisions that may affect the budget year have been considered previously in the long term planning process which is the starting point for the annual budget. Thus the top level managers need to communicate the effect of the policy to the people who are responsible for the preparation of the budget of current year. The effect of the policy

Googles dilemma Case Study Example | Topics and Well Written Essays - 500 words

Googles dilemma - Case Study Example When Larry Paige and Sergie Brian hit upon the idea in 1998, the concept of search engine was still vague. Thus, Google’s success lies in tapping the search engine space and as it grew exponentially; it had to evolve into some kind of structured organization if it had to maintain its astounding growth rate. Summary of the situation: The tile of the case about the â€Å"dilemma† faced by Google is how to motivate and energize its young staff while maintaining a semblance of formalized structures. The key is to incubate new ideas in an organization while having some sort of bureaucratic structures in place to sustain its growth. SWOT The strength of Google is innovation and the workforce that prides itself on being â€Å"geeky† but resents formalized structures. Google derives its main strength from the way in which employees use their spare time to sound off on potential ideas that can be the â€Å"next big thing†. The weakness of Google lies in the way in which it is grappling with establishing formal governance structures. This is a classic dilemma faced by many technology companies: How to grow without making the workforce feel that are part of an â€Å"impersonal† and â€Å"mechanical† organization. Google’s opportunity is the ever growing web applications market that has seen it grow at an annualized rate of around 30% over the last few years. The vitality and creativity of the workforce is another area of opportunity. Finally, the threat to Google is two-fold: potential start-ups like cuil.com that were started by ex-Google employees and can eat into its search engi ne market. Second, the rising headcount that now stands at over 6,000 can make it a victim of its own success. Recommendations: it is recommended that Google’s management team inculcate a spirit of structure and formalized communication channels instead of the â€Å"college† atmosphere that

Duhem and the Good Sense of the Physicist Essay Example for Free

Duhem and the Good Sense of the Physicist Essay This paper will examine Duhem’s good sense of a physicist. We will also succinctly discuss his reason behind this claim. To explain Duhem’s good sense of a physicist, different experiments involving systematic procedures will be inspected, and J. J. Thomson’s experiment on cathode ray tube is one of these experiments. Two hypotheses about electricity that received worldwide acknowledgement will also be discussed. The explanation of these hypotheses will further question Duhem’s claim on the good sense of a physicist. Jean Perrin’s contradictory presentation about the effectiveness of experiments in testing hypotheses contributes to the goal of this paper. The Good Sense The good sense of Physicist examined by Pierre Maurice Marie Duhem (1861-1916) can be used to determine very confusing and contradicting experimental results. He encouraged the use of this ‘good sense’ since there are discoveries that doesn’t require extensive experiments and the ‘good sense’ of the physicist will be the guide to solve a problem. Duhem argued that this is enough to accept a good and well-explained hypothesis. He also encouraged the revision of a claim to accommodate and balance a confusing experiment. However, this method is too ambiguous and irrational especially for those tests that needed extensive experimental guidance. The use of the good sense is too risky for future purposes. One good move that we can consider to refute Duhem’s claim about the good sense of a physicist is to examine the approach used by different scientists. Sir Joseph John Thomson’s (1856-1940) experiment on the cathode rays and the cathode ray tube prompted an innovative period in the field of electricity. This experiment led to the discovery of electrons and other subatomic particles, a breakthrough that enhanced the understanding of the composition and behavior of matters. Three different experiments were performed using these cathode ray tubes. Thomson first used magnetism to see if there is a chance that the negative charge will be separated from the cathode rays (Park). Further elaboration of this experiment led him to the conclusion that the negative charge and the cathode rays are inseparable. In his second experiment, his main objective was to know if the presence of an electric field would influence the projection and behavior of rays. He constructed a nearly perfect cathode ray vacuum because he believed that previous experiments failed because of the presence of different gaseous element in the air. With his subsequent procedures, he was able to prove that the electric field could really influence the movement of rays because these rays were deflected, signifying the track of the negative charge. Thomson’s third experiment involves the measurement of the charge-to-mass ratio of the cathode rays. He measured the amount of cathode rays that were averted due to the presence of a magnetic field. He also measured the amount of energy they have. His observation led him to conclude that either the particles were very light or greatly charged because the charge to mass ratio was more than a thousand times greater compared to a hydrogen ion. Thomson’s hypotheses were proven not just because of merely theorizing. He proved it because he followed a systematic procedure. His path was guided by previously known facts. He was also guided by the failures of earlier experiments. In 1913, there were two hypotheses that had gained universal acceptance. The first one states that electricity occurs in discrete fundamental units. The second hypothesis states that the magnitude of the negative charge is three times smaller than the smallest mass associated with the fundamental unit of positive charge. The development of these hypotheses was brought about by the continuous growth of awareness in electricity. The discovery of the Avogadro’s number, mle and e of the constituents of various electrical discharges, mle and e of gaseous ions, and the total charge of a mole of monovalent ions Ne gave rise to this outcome. Duhem should give importance to the experiment conducted that supports these hypotheses. According to Jean Perrin, hypothesis, in most cases, is both essential and productive (Soshichi). He explained it in terms of examining a machine. He said that we do not just study a machine by just considering the visible and tangible parts. We will go as far as our eyes can tell us if we only consider this. Aside from these visible parts, we also seek the properties of the hidden gears that can explain its evident motions. To explain this, we must relate the visible parts to the invisible parts. If it is outside our scope of understanding, we seek retribution by studying its components part. There we formulate our hypothesis. Because we have the intuitive intelligence needed in solving such complex problem, Perrin added, we were able to give rise to the doctrine of Atoms. Perrin’s method is mainly based on experimental foundations. We can divide Perrin’s experimental inquisition into two. The first division is consisting of checking whether the result of an experiment follows a given algebraic distribution. The second step involves using approximation of the coefficient of diffusion, which is vital for gaining the Avogadro number. According to Duhem, a physicist can never test an isolated hypothesis. A physicist can never leave the theory outside the door of the laboratory since a failed prediction or experimental test cannot tell a scientist where the error lies. It can only tell him to examine further the experiment and try not to commit the same mistake. In our modern times, a hypothesis is not valid unless it is tested. In this paper, we have succinctly discussed his reason behind this claim. To explain Duhem’s good sense of a physicist, different experiments involving systematic procedures was inspected, and J. J. Thomson’s experiment on cathode ray tube is one of these experiments. Two hypotheses about electricity that received worldwide acknowledgement were discussed. Jean Perrin’s contradictory presentation about the effectiveness of experiments in testing hypotheses contributes to the goal of this paper. The good sense amounted in this case is the rational way a physicists approach a problem. They used experiments to support their claim, not just downright theory. The good sense of a physicist accounts for his sense of creativity, how he develops his own way of obtaining an answer to a hypothesis. All of this is through experiments.

Strategies for Depository Companies in Financial Crisis

Strategies for Depository Companies in Financial Crisis Introduction The development of capital markets is highly dependent on the activities of related securities market infrastructure institutes that include, inter alia, depository companies engaged in provision of the services for record-keeping of entitlements under securities (registration and transfer of rights to securities), collection of coupon and dividends (payable income) arising from the portfolios, facilitation of corporate actions processing (such as tender offer, proxy voting, buy-backs), and other services. This study focuses on the issues and relevant remediation steps applicable to depository companies being integral part of the stock market infrastructure. Recent volatility in the stock markets provided a positive impetus to change the business model of depository companies. Securities market participants seek to use the services of depository companies as an additional measure of protection for a significant amount of assets and portfolios. Moreover, the market is shrinking and brokerage houses are going bankrupt that also boosts customers desire to move their assets to specialized players in depository business by establishing direct relations. Nevertheless, the global turmoil has affected the research market segment resulting in rapidly decreasing value of assets under custody, reduction of on-exchange and OTC trading volumes, and redistribution of portfolios of assets by risk-averse investors seeking alternative strategies in times of crisis. Keywords: capital market, strategic alternatives, competitive strategy, depository services. The objective of the research paper is to identify the key strategic options that would increase economic profit of the depositories’ organizations amid ongoing financial crisis. Effectively, we would like to develop and propose different approaches towards the companies’ strategic options aimed at defining current condition, future growth factors and drivers for relatives companies of the market segment. The findings section of the research paper describes most topical problems that depository companies are currently facing in Russia. The economic value drivers are identified and can be used to translate them into the economic profit model of depository companies. Furthermore, the main strategic options are identified to highlight client portfolio rebalancing opportunities in the market segment. Methodology The methodological base of the research paper is based on the analysis of data and information available in public sources, and made through desk study, along with the opinion expressed by the market experts. The following sources of information were used for different sections of the report: Legal framework: federal laws on securities and custody operations, information on securities market volumes and other statistics was retrieved from the Russian National Association of Securities Market Participants (NAUFOR) and the Central Bank of Russia (CBR) official web-sites, the official publications and documents of the Federal State Statistics Service (Rosstat), and the Ministry of Economic Development; The problems were identified through interviews conducted with securities market specialists in Russia; Securities services sector development: the data was retrieved from annual NAUFOR Russian Stock Market. Facts and Events survey of 2014. The research paper is represented by six chapters that include introduction, methodology, the main part – hypothesis, findings, conclusion, footnotes and bibliography. Hypotheses We suggests the following hypotheses to be tested in the course of empirical research: Hypothesis 1: The growth strategic alternative (merger / acquisition, and integration / alliance) is winning in terms of achieving the objectives set by the company during crisis. Criteria: Cost-saving through synergies with other small providers; introduction of new product offering. Hypothesis 2. Companies that apply product expansion strategy instead of infrastructure needs can be more effective during crisis times, create competitive advantage and fulfill the objectives of the company. Criteria: The presence / absence of the relation between the degree of product diversification of the company (interoperability with the Central Depository, Central Counterparties, communication standards) with product standardization. Hypothesis 3. Depositories companies prone to invest in quality assurance (service organization), rather than implement cost reduction strategies. Criteria: The presence / absence of large market players, including investment funds and wealthy individuals. Characteristics of the research object Object depository companies that provide services to broker / dealers, investment funds, private individuals and other depositories. Characteristics and features of the market segment: Approximately 570 companies. From 15 to 80 employees. Revenue from 0.1 to 5 million dollars a year. Clients local and foreign residents. Entry barriers – licensing requirements, IT technology, staff competencies. Large number of small companies with a small scope of operations and market share. Trend towards consolidation of businesses. The market segment of the securities market industry has a number of distinctive features that influences application of discussed strategic alternatives in the crisis. Findings The current global financial crisis requires depository companies to respond quickly to all macro-environment changes and stay competitive player with large amounts of assets deposited. The securities services are fairly stable line of business, where the client portfolio (equities and fixed income instruments) size is crucial and steady income for the maintenance would facilitate the development of the company. However, the depositary companies are affected by unstable situation, which is observed in the stock market in recent years. Therefore, we would like to see new threats and opportunities that have emerged recently. We analyze the strategies of corporate governance of companies affected by the financial crisis on this basis, the following assumptions that were designated for the research paper: We assume that all actions are undertaken in the interests of the stakeholders of the company or business. Set of strategic alternatives designated for the management in order to adjust the companys goals, drivers and incentives. It should be aimed at achieving long-term stability and development of the companys competitive advantages. We offer three strategic alternatives focused on the development of depository companies. Strategic integration opportunity is aimed at further increasing the scale of production for the purpose of reducing the share of the unit cost. The implementation of the strategic alternative is expected to be done either by improving production processes or acquiring other depositary companies of market segment for the purpose of achieving the economy of scale. The strategy also suggests the possibility of further acquisitions and development of the most profitable depositary companies of the group. The strategy of product expansion in companies offering depository services promote the interests of customers and investors in attracting new portfolios. This strategy, however, requires a systematic approach and professional competence to be successful. The Russian capital market has grown rapidly over the last 15 years, but the securities market infrastructure could not keep up the pace. Effectively, depository companies that had specialized in improving the securities market infrastructure of the stock market, promoting new electronic document interchange, new product offering and interconnection services, can achieve success in the crisis. Given the opportunity to work with local authorities on the development of the securities market infrastructure in the long term they can lead to key roles in the value chain. These depositories companies has a fundamental knowledge and significant resources to identify and resolve discrepancies in connection with the accelerated development o f the stock market. The strategic alternative of the service organization if they can meet service level claimed by sophisticated investment funds, private individuals and global custodians forced by the credit crunch to hold their assets through depository companies using them as extra protection during the financial crisis. For depository companies, there are many opportunities to retain these customers and grow the business, if they can agree and guarantee services that their customers demand. Nevertheless, many questions arise when thinking about the possibility of service in the framework of this strategy, there is no innovation component. It may be difficult to implement such a strategy for large depository companies whose business models are based on cost reduction and unification of services provided. However, the innovative component cannot be a panacea for all the ills in the short term. The decisive role is played by the demand and requirements of the customers and investors, and also monitor ing and control regulatory bodies. Business model of depository companies are highly dependent on the cost of fees for safekeeping as a percentage of total assets in custody, as well as fees for each transaction in securities. Probably the situation could become worse, given the negative reaction from politicians and regulators in light of the financial crisis. One of the key areas which will have an impact on the financial services sector is information transparency. Stagnation of business activity in the stock market has provided many opportunities for depository companies, and put some pressure on the volume of investment and resources management companies. Business and operational models were tested under the conditions subject to increased demands of customers in the pursuit of improving the quality of service and flexibility of services provided. The rapid reduction in the value of client assets under custody put pressure on revenues and spending in order to remain profitable. Conclusion The practical conclusions of the study can be summarized as follows: The specific strategic alternatives have been formulated for depository companies acting in a financial crisis. Each option describes opportunities and focus group, and is presented as optimal one for the company with certain level of expertise and specific client types. Each of the strategic alternatives is aimed at selected market participants and shall provide opportunities to survive, improve operational activities, and also to strengthen their position in the market segment. In conclusion, we notes that at the present time, when the whole world is deepening the financial crisis, more and more companies risk losing their ability to pay. Accordingly, it is necessary to pay more attention to the anti-crisis strategy of corporate governance. Bibliography Rubcov B.B. Modern Financial Markets M.: Alpina Business Books, 2007. – 926 p.

The TV Made Me Do It Essay -- essays research papers

Violence on TV affects how children view themselves, their world, and other people. In fact, experts warn that viewing violence can have lifelong harmful effects on children’s health. By the time children complete school, the average child will witness more than 100,000 acts of violence on TV, including 8,000 murders. The more violence children watch on TV, the more likely they may act in aggressive ways, become less sensitive to other’s pain and suffering, and be more fearful of the world around them. Since we live in a violent society, we’re constantly hearing arguments that seeing TV violence, particularly children, desensitizes us so we accept real violence more easily and maybe it even triggers real violence. The theory behind the TV attacks is always the same: if Bobby commits a crime, he’s not responsible and his parents are not responsible: something else is responsible.   Ã‚  Ã‚  Ã‚  Ã‚  The problem in this society isn’t the easy availability of drugs, or guns, or television, although all are scapegoted. All of these things simply do only what we have them do. All supposedly scientific studies on the subject of TV violence causing real violence are based on a theory of cause-and-effect that goes against humans having the capability of making responsible, moral choices. So is the media causing the nation to stray away from the â€Å"old fashion valuesâ€Å"? We are voluntary beings by nature: we chose what we do and what we make of ourselves. For example, you take...

The Struggle of Revolutions Essay -- War American History Government E

The Struggle of Revolutions _ Have you ever wondered why were revolutions fought for? Why in some cases they had to risk millions of lives in order to have a successful revolution? And how does these turnovers that were fought in our past affect us today? If we look at the history of revolutions, we can find revolutions almost in any country on earth. But three of them were a main revolutions that on their steps, and by the influence of them, other revolutions had been fought. They are: The Glorious Revolution, The American Revolution, and The French Revolution. But when we look at these three in History, By studying them we can find lots of similarities and correspondences. As these three shakeups were closely followed by each other. We can find similarities in every two of them; as follows: The Glorious Revolution which was the first, shared some consequences, and issues with the American Revolution. And for the French Revolution which followed the American Revolution and influenced by it, had also some in common. And same as for both The Glorious, and French Revolution. No one could ever expected the extreme impact of the Glorious revolution over the American revolution and their similarities. In 1685 the Glorious Revolution occurred. In 1776 the American Revolution had begun after announcing The Declaration of Independence. Even though, the Glorious Revolution shared so many similarities; there was a slight difference about it. But these issues that have been shared in between, were amazingly straight to the eye. â€Å"A continuation of the struggle between the crown and parliament, sums up the powers that parliament had been seeking since the petition of rights† _The English Bill of Rights document. â€Å"By authority of the god people of these colonies, solemnly publish and declare, that these United Colonies are, and of right ought to be free and Independent States†_The declaration of Independence document.

The Glorious Revolution had obvious similarities with the American Revolution, the American Revolution strongly affected the French Revolution, Glorious Revolution also shared; even though little similarities with the french Revolution. They all communicate with each other, they influence one another, as they were all one by one came after another. All these Revolutions were fought in the process of making and getting a better government and democracy for the people. And we ask ourselves; Did it all stopped over getting a better government and winning the democratic principles and rights? And why were Revolutions an important point and emphasis where it changes and effects the lives of the people of the future generations in the history of the people and nations? Some answers may be found in these lines that I wrote, but still there are plenty of reasons why Revolutions are still fought for. Even in our world today there are still people dying in their countries struggling to achieve Democracy. Blood still the price in the people’s conquest to gain their rights and democracy. For better Government; for better Life.

Into the wild Essay

Fool or Hero? Into the Wild is a book about a young man named Christopher Johnson McCandless, who had a very bright future but threw it all away by hiking into Alaska unprepared and alone. Chris McCandless can be labeled a hero, somebody to be admired or a fool. He can be called a hero because he showed people through his own actions how to live free and not be controlled. He can be called a fool because he had a good education and a bright future but he chose to go unprepared into the wilderness and risk his life and eventually die. In April of 1992 Chris who grew up in a well to do family, decided that he wanted to hitchhike to Alaska and walk alone in the wilderness of Mt. Mckinley. Before Chris decided to do this he had a nice future ahead him. He graduated with honors from Emory University in the summer of 1990. Chris was smart and he was an elite athlete. Right after he graduated he disappeared. â€Å"What no one knew- was that he would shortly donate all the money in his college fund to Oxfam America, a charity dedicated to fighting hunger† (Into the Wild: Pg. 20). He also burned all of his cash, abandoned his car and basically started his life from scratch. Chris also told the strangers he encountered that his name was Alex. Because of this his family couldn’t trace him and find him. Although Chris foolishly did go out into the wild without any experience or any method to survive he can be considered a hero/someone to be looked up to. By trying to hike in Alaska he showed people that they can live their lives however they want to, be independent and make their own decisions. Through his actions he is truly showing what independence means. No matter how many people tried to stop him from trekking in the wilds he would never give in. Chris tells Ron, a retired army veteran who he meets in his travels, â€Å" Look Mr. Franz, you don’t need to worry about me I am not destitute, I am living like this by choice† (Into the Wild, Pg. 51). He was always motivated to be independent and didn’t let anyone make decisions for him. Chris also tells Ron, â€Å"you should make a radical change in your  lifestyle and begin to boldly do things which you may previously never have thought of doing, or been too hesitant to attempt† (John Krakauer, Into the Wild). By saying that he is telling Ron to explore the world, not to listen to anyone else and go wherever his heart takes him. Chris can be looked up to if they get his real message. Chris wasn’t necessarily saying people should hike to Alaska but he was saying that everyone could control their own lives. There are many reasons why Chris McCandless is a fool for both ruining his life and getting himself killed. He was a good student in school and could have had a very bright professional future, but he rejected graduate school. He was a well-known athlete so he could have had friends but he didn’t want any. He had a savings of 25,000 dollars and he just gave it away. He could have used the money to live a regular life. Instead of living life like a normal person he decided to disappear without telling his family and hike to Alaska. Even the way he travelled was foolish. When he started his hike alone his odds for surviving were already low because it’s almost impossible to hike through Alaska alone. He was even more foolish because of the lack of supplies and food. He only brought a bag of rice to eat. The gun that he brought wasn’t powerful enough to take down a grizzly bear or any bear if he saw one, so he was not able to protect himself. So Chris can be known a s a fool because he underestimated the value of education, family and didn’t prepare properly for surviving in the wilderness of Alaska. In some peoples eyes Chris is a hero and in others Chris is a fool. He got himself killed by hiking to Alaska but at the same time he was sending a positive message out to everyone. Chris is saying that â€Å"It is easy, when you are young, to believe that what you desire is no less than what you deserve, to assume that if you want something badly enough, it is your God-given right to have it† (Jon Krakauer, Into the Wild). Although the way Chris tried to prove his point made him look foolish he was only doing it for good reasons. People never understood why Chris threw away his life, but that’s because Chris only did what he wanted to and he showed us by example how to be in control of our lives.

Human Race

A response to Mark Twain’s â€Å"The Lowest Animal† (1896) By: Thanusha Sritharan Is the human race cruel or just selfish? The human race is one of many distinct species in the world. Human beings share most of their traits and behaviors with other animals. The act of cruelty and violence to one another is one of the behaviors that humans differ from animals. In the essay â€Å"The Lowest Animal† (1896), Mark Twain claims that man can be cruel and wasteful in his lifetime. Although his statement does not imply to all humans, the moral sense enables us to do wrong.With the proof of news reports and media it is evident that man is cruel to animals, the society and to their household. When compared to people, dogs are known as a man’s best friend. Even though they are four-legged canines, dogs have a heart like gold. Dogs are also known for their ability to help people with visual impairments. They are very loyal and lovable to their owners and others. A stud y conducted by Mark Franz states that dogs happen to have a higher level of decency when compared to humans. In Toronto, a 32-year old woman, Alice Marcial, strangled her pet dog Jacob to death.This news article is very relevant to Mark Twain’s quote â€Å"Of all animals man is the one that is cruel. He is the only one that inflicts pain for the pleasure of doing it† (pg. 238). Not only do humans find pleasure by inflicting pain on animals but they also engage in public killings as a source of entertainment. Many people in the world live their life according to their sets of beliefs and values. In the world we live in today people feel the need to judge and have a say in others life choices. In Papua New Guinea, a mob tortured a group of woman who was accused of witchcraft.This mob tortured this group alive in front of hundreds of horrified witnesses including their family. To support this news article a quote my Mark Twain can be used, â€Å"Man is a religious animal † (pg. 237). This quote proves the fact that a man loves his religion and he only plays by his religion. Although witchcraft is not a religion it is something that group believed in. The act of shunning someone based on their religious choices is morally wrong and should not lead to any form abuse or death. In third world countries people abuse children in my different ways just to teach them a lesson.This happens every single day to millions of children around the world. Child abuse is something not to be taken easily. It is seen as a major social problem and it is one of many causes of the children’s death. For example, in Saudi Arabia a five-year-old Saudi girl was beaten to death by her father when in front of her entire family. There was no specific reason for this abuse but it cost the life of a five-year old girl. This news article can be supported by a Mark Twain quote, â€Å"Man is a cruel animal† (pg. 237).This quote proves the fact that man could do an ything to accomplish something regardless of who the victim is. With the proof of news reports and a study it is evident that man is descended from animals. Some people choose to do evil things even though they have conscious of what they are doing. A reason why people do this is because the moral sense enables men to do wrong. In the world we live today everyone makes mistakes. In fact this is not an excuse to make a cruel, unforgiving fault that could change yours or that person’s life.

Further, it prepares the tax expenditure to show its spending and spending via the tax system. Yes, it prepares fiscal impact statement to predict how the authorization of a ballot measure would affect the finances of the state. When preparing revenue forecasts, it significant for the local government financial accountants to begin with expenses not revenues since in this manner, it much easier to predict expenses than expenses. In addition, it significant to predict revenues utilizing both an aggressive and conservative case because aggressive state keeps one motivated while conservative state brings reality on the ground. It is also good to monitor key ratios to ensure that the projections are logically and

Martin Luther King Essay Example | Topics and Well Written Essays - 1750 words

Martin Luther King - Essay Example He was ready, to accept the leadership of the first great Negro nonviolent demonstration of contemporary times in the United States, abruptly a boycott was met by fury in Montgomery's white community and that brought national attention to the problem of segregation. King helped lead Montgomery's blacks on a yearlong nonviolent boycott of the bus system, the boycott ended after 382 days only when the U.S. Supreme Court intervened and declared Alabama's segregation laws unconstitutional on buses. After the verdict of the Supreme Court, Negroes and whites rode the buses as equals. During these days of boycott, King was arrested, his home was bombed, he was subjected to personal abuse, but it was at that time he emerged as a Negro leader of the first rank. Two events in January 1956-his arrest and incarceration for allegedly speeding and the bombing of his house-brought King's personal life into the larger context of Black America's struggle for justice and dignity. In my opinion this was the time in King's life, which created a leader out of him. This leader who contributed towards the Black-Americans was the outcome of all his frustrations, this was the result of his personal sufferings that led him onto the road of leadership. Though the political situation is at times dark and tense, we experience a certain vicarious thrill in witnessing the growing self-confidence with which King engineers a successful resolution of the Montgomery Bus Boycott. Another incident occurred in Birmingham on the 16th Street Baptist Church where Martin Luther King, Jr., and hundreds of other African-Americans met and planned sittings and demonstrations for equal rights when one of the most horrific events in the long struggle for African-American civil rights took place. Denise McNair, Carole Robertson, Cynthia Wesley, and Addie Mae Collins were preparing for Sunday services in the basement dressing room of the Baptist Church when a dynamite bomb planted outside exploded, killing four girls and blinding another in one eye. Two of their killers remained beyond the grasp of the law for nearly 40 years. King was convicted here as a killer of those four girls just because of the fact he was disliked by the then director J. Edgar Hoover due to no others reasons but he was 'Black American'. The wheels of justice proved to move slower than the dismantling of segregation. It wasn't until 1977 that Robert (bomber) was found guilty for his role in the bom bing and sentenced to life in prison, where he later died. The tragedy galvanized the civil rights movement and helped lead to enactment of the Civil Rights Act of 1964. Progress did not come easily, however. King was a frequent target of violence. On multiple occasions he was physically assaulted, and his home was bombed several times by vigilantes. Almost daily he received death threats and hate mail. Yet he and the movement persevered even with the

MEDICATION ADMINISTRATION ERROR - Essay Example Active errors assume different forms including lapses; this involves failures in memory that prevents the planned actions from being implemented. Slips; this involves performing a familiar action in a wrong away. Mistakes; are refereed to as a trend of reasoning leading to wrong outcome of choices. Latent conditions refer to systemic properties that result to errors. They may include system interfaces and management practices. It is summarized by the descriptions of Don Berwick that â€Å"every system is perfectly designed to achieve exactly the results it gets.† The nature of today’s primary care and frenetic pace of management in care within medical practices have made the probabilities of errors to become great. The Robert Graham Policy Centre has come up with a patient safety model called â€Å"toxic cascades.† It describes how small unnoticed errors can add up to become torrents. Research studies on office-based errors in primary care have been found to be of different categories. It shows that communication problems results into 24% of the errors, 20% are caused by discontinuity of care, 13% are as a result of missing charts, 19% from lab results, 8% are caused by clinical mistake, 8% resulted from prescribing errors, and the other 8% by other errors. The study revealed that medical errors are by and large a result of latent conditions and not active failure as had been believed. The medical infrastructure has become fragile and the risk adverse outcomes has gone low, despite the fact that delayed care, patient dissatisfaction, and worsening illness are still very common concerns in medical practices. Studies on error in health care by the National Patient Safety Foundation (NPSF’s) have led to the conclusion that â€Å"the ambulatory inpatient dichotomy is a false one. We have to think about populations and their continuum of care.† (Brennan, 2000). Turnbull the executive director of NPSF’s has put

Project Management - Research Paper Example In this, they prepare the initial timeline of the project and determine the preliminary costs of the project. Either in the conception phase, the management can establish the project user participation and the possible sources of funds. Finally, the management may decide if to continue with the project or alter (Lewis, 2007). Therefore, the initiation phase forms the most crucial stage of the project than all the other stages. It is the foundation stone laying stage that without it the progress of the project is futile. The second phase is the project-planning phase. Here, the management commences setting out the project plan. This involves reviewing of objectives and goals of the project. Besides, the management considers the strategies needed to achieve these goals and objectives (Lewis, 2007). In this, they think each activity is leading to the sequencing of activities that will open up to be the required project. In the planning phase, the management allocates time to sequencing activities and develop a risk management plan (Lewis, 2007). Either, they evaluate on the resources needed and their cost. Finally, in planning, they allocate budget to individual resources to ensure that the project will run efficiently. The third phase is the project launch or execution phase. This stage involves Performance of activities and tasks as planned. Management evaluates the overall performance to ensure that the project meets the set quality standards (Lewis, 2007). Besides, there is development individual and team skills aimed to enhance project performance. In addition, the information about the project is distributed to the stakeholders to attract the needed investors (Lewis, 2007). In this phase, also the management may select potential partners and outsource vendors. Then there is the project performance control. This is responsible for coordination of the change control across the entire project. It involves verification of the scope of the

An Evaluation of Traditional Concepts of an Individual Essay

An Evaluation of Traditional Concepts of an Individual - Essay Example There were also those who have sought personal glory and conquests, individuals like Napoleon Bonaparte, Adolph Hitler and Julius Cesar all of which had their own vision and version of the "ideal society" in which they sought to dominate. And finally there were those who have been known for their infamy and notoriety, otherwise known as deviants or villains. Is there anything that separates them and the other individuals The answer may be lie on the fact that these individuals may have discovered what it takes to be an individual that can stand above others. Or perhaps they have not been aware of the fact that they were exceptional or maybe they made their purpose clear to themselves that they want to achieve something that will grant them dominion above others. In any case, the individual is truly unique and each has the potential of unimaginable glory and achievement. This paper discusses some traditional and conventional concepts of the individual like how and what it take to be a n individual, how does the individual perceive his or herself, how are they able to cause either damage or benefit the environment and other individuals that they have been involved with. Any normal person would refer... Individual's posses a high sense of self that they have may have acquired during the early stages of development. The term "human being" has been the subject of debate for years, but in the traditional sense is synonymous to a person or an individual. Some sociologists and anthropologists adhere to this classical definition of the person while some say that this definition should be expanded. Others have proposed a total redefinition of what a person is. The classical definition is quite tricky, a person may also be defined as someone who is entitled to basic rights but then there are also other beings that are entitled to such rights such as the right to live for example ("Persons"; "Cultural Identity"). Some psychologists have been in fact went to as far as defining a person as a gestalt of thoughts and never defining it in the material sense, although this is too extreme. The individual can be defined when one is aware of his or herself. This "Conscious Theory of the Mind" suggests that the individual creates a mental image of his or herself a sort of "mental construct" which is distinct from anybody else. In an experiment by George Gallup in 1970, he demonstrates that some higher primates like chimpanzees. This experiment was a variation of the "Mark of Rouge" experiment where children a year old or more were written with a "mark of rouge", actually an erasable mark made with a crayon, in their foreheads. The child was placed in front of a mirror and was let to observe his or herself. Most of the children in the age of exactly one year reacted to their mirror image as if they saw another child. Older children simply wiped away their "rouge markings" once they observed

United States Deficit Essay Example | Topics and Well Written Essays - 500 words

United States Deficit - Essay Example of the Federal Reserve, 6 % of State and Local Government, domestic and private investors 32% and the major portion of was the international investor who offered 46 %. These are the four most important places where U.S was able to borrow money from. The international investors like BP, DaimlerChrysler, ING group which are located in different countries like U.K and Netherlands provided the U.S with a major portion of the credit. Once this money is borrowed, both parties have to come into an agreement on how the interest will be paid. Once the U.S has borrowed money, they will pay the interest rates depending on each countries agreement with the U.S government. They can also exchange privileges. This means that that the U.S government can give an investor the opportunity to be able to switch from one mutual fund to another with the family without paying sales charges. Credit rating is a method used to evaluate the credit worthiness if a debtor and this can be a business or a government. This is done by a credit rating agency like Moody’s, Fitch Ratings and Standard & Poor. . The credit rating of a government like U.S is a financial indicator to potential investors of securities like bonds. The Credit rating agency Standard and Poor (S&P) downgraded its credit rating of the U.S federal government from AAA (outstanding) to AA+( excellent) by the third quarter of the year 2011. This seems not to be good news to the U.S as international implication of public deficit will lead to higher current accounts deficit, it will also increase the risk of capital flight this affecting the image of the country. This will make international investors to shy away from investing in this country. The current account is a component of the balance of payment while the other being capital account. The current account balance measures the nature of a country’s foreign trade. The capital account determines how international capital flows and investment are recorded in the capital

CPA vs. Non-CPA Essay Example for Free

CPA vs. Non-CPA Essay Many people may ask, â€Å"What are the differences between being a CPA and just being a non-certified CPA,† there are actually a lot of differences between the two. A CPA or Certified Public Accountant is someone who has a license to practice public accounting that is issued by their State Board of Accountancy. CPA’s, in contrast, have normally studied or majored in accounting during college, sat for the CPA exam, worked in an accounting firm for at least two years, and completed 500 hours of auditing work in order to earn their certification. CPA’s are also required to complete a certain number of continuing education hours in order to keep their CPA license. A CPA can complete all three types of financial statements including: audited, reviewed, and compiled. â€Å"Non-certified accountants can simply hang up their shingle and open their doors for business† (Day). For non-certified accounts there are no educational requirements, however, in order for them to prepare taxes most states require that they complete a certain number of hours of the study of accounting and also complete continuing education hours per year. Non-certified CPA’s can only complete the last type of financial statements which is complied. The main question is how to choose whether to choose a CPA or non-certified CPA. â€Å"It has to do with the concept of free enterprise. Remember the old adage, Caveat Emptor? It means let the buyer beware† (Day). It is the client’s responsibility to choose the most qualified professional. Obviously, the auditing and review types of financial statements cost more than a complied one but some banks require a review of your books in order to receive a bank loan, so it would be in the clients best interest to have a CPA they trust already.

The Process Heat Exchangers Engineering Essay

The Process Heat Exchangers Engineering Essay In this chapter, a full unit of heat exchanger will be designed including its chemical and mechanical design. A heat exchanger is a device built for efficient heat transfer between two fluids from one medium to another. The medium may be separated by a solid wall, so that the fluids never mix, or the fluids may never be in direct contact. Two fluids of different temperatures will flow through the heat exchanger. Heat exchangers are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, and natural gas processing. 3.1.1 Classification of Heat Exchanger Heat exchangers may be classified according to their flow arrangement. There are two main flow arrangements which are parallel-flow and counter-current-flow. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side. In counter-flow heat exchangers the fluids enter the exchanger from opposite ends. Compared both flow arrangements, the counter current design is most efficient, in that it can transfer the most heat from the heat transfer medium. 3.1.2 Types of Heat Exchanger There are many types of heat exchanger in industry. The types chosen based on the function of the heat exchanger itself. Choosing the right heat exchanger requires knowledge of different type of heat exchanger as well as well as the environment in which the heat exchanger will operate. With sufficient knowledge of heat exchanger types and operating requirements, the best selection can be made in optimizing the process. Below, in Table 3.1 are list of types and functions of each heat exchanger. Table 3.1: Types and Functions of Heat Exchanger in Industry No. Types Functions 1. Double pipe heat exchanger The simplest type. Use for heating and cooling. 2. Shell and tube heat exchanger Used for all application. 3. Plate exchanger Use for heating and cooling. 4. Plate-fin exchanger Use for heating and cooling. 5. Spiral heat exchanger Use for heating and cooling. 6. Air cooled Cooler and condenser. 7. Direct contact Cooling and quenching. 8. Agitated vessels Use for heating and cooling. 9. Fired heaters Use for heating and cooling. Source: Chemical Engineering Design, R.K.Sinnott. 3.1.3 Selections of Heat Exchanger Typically in the manufacturing industry, several different types of heat exchangers are used for just the one process or system to derive the final product. In order to select an appropriate heat exchanger, one would firstly consider the design limitations for each heat exchanger type. Although cost is often the first criterion evaluated, there are several other important selection criteria which include: High/ Low pressure limits Thermal Performance Temperature ranges Product Mix (liquid/liquid, particulates or high-solids liquid) Pressure Drops across the exchanger Fluid flow capacity Clean-ability, maintenance and repair Materials required for construction Ability and ease of future expansion 3.2 BASIC PRINCIPLES OF DESIGN 3.2.1 Design Criteria for Process Heat Exchangers There are some criteria that a process heat exchanger must satisfy are easily enough stated if we confine ourselves to a certain process. The criteria include: The heat exchanger must meet the process requirements. This means that it must effect the desired change in thermal condition of the process stream within the allowable pressure drops. At the same time, it must continue doing this until the next scheduled shut down for maintenance. The heat exchanger must withstand the service conditions of the environment of the plant which includes the mechanical stresses of installation, startup, shutdown, normal operation, emergencies and maintenance. Besides, the heat exchanger must also resist corrosion by the environment, processes and streams. This is mainly a matter of choosing materials of construction, but mechanical design does have some effect. The heat exchanger must be maintainable, which usually implies choosing a configuration that permits cleaning and replacement. In order to do this, the limitations is the positioning the exchanger and providing clear space around it. Replacement usually involves tubes and other components that may be especially vulnerable to corrosion, erosion, or vibration. The cost of the heat exchanger should be consistent with requirements. Meaning of the cost here implement to the cost of installation. Operation cost and cost of lost production due to exchanger malfunction or unavailable should be considered earlier in the design. The limitations of the heat exchanger. Limitations are on length, diameter, weight and tube specifications due to plant requirements and process flow. 3.2.2 Structure of the Heat Exchanger The basic structure of heat exchanger is the same whether using hand design method or computer design method. The logical structure of the heat exchanger design procedure is shown in Figure 2.15. From the figure, clearer view and steps of designing a heat exchanger can be obtained. Figure 3.1: Basic Logical Structure of Heat Exchanger Design 3.3 CHEMICAL DESIGN 3.3.1 Problem Identification In designing a heat exchanger in production of 100, 000 metric tonnes/year of Acrylonitrile, there is only one heat exchanger exists. The function of it is to exchange the temperature between the stream from Reactor with the temperature from 125 °C to 25 °C and the stream comes from Reboiler 5 from 90 °C to 120 °C. 90.0 0C 125.0 0C 450.0 0C 120.0 0C Figure 3.2: Diagram of shell and tube heat exchanger 3.3.2 Determination of physical properties Table 3.2: Physical Properties of the tube side fluid (water) Properties Inlet Mean Outlet Temperature (0C) 90.0 105 120 Pressure (kPa) 70.139 120.82 198.52 Specific heat (kJ/kg0C) 4.204 4.224 4.249 Thermal conductivity (W/m0C) 0.1154 0.1198 0.1127 Density (kg/m3) 0.431 0.623 0.721 Viscosity (N sm-2) 3.145 x 10-4 2.677 x 10-4 2.321 x 10-4 Table 3.3: Physical Properties of shell fluid ( process fluid) Properties Average Temperature, Tave = 287.5 0C Pressure (kPa) 150 Specific heat (kJ/kg0C) 1.1 Thermal conductivity (W/m0C) 0.1553 Density (kg/m3) 1.255 Viscosity (N sm-2) 4.529 x 10-4 Only the thermal design will be carried out by using Kerns method.

The highest value from these two types of wall thicknesses is 0.12334 inch, so the minimum wall thickness of this heat exchanger is 0.12334 inch (3.133mm). The nominal wall thickness for carbon steel at market is 0.1182 inch (3mm). Because of the nominal wall thickness is lower than the calculated we must take the calculated thickness t = 0.12334 inch (3.133 mm) as value of wall thickness. To calculate the maximum allowable working pressure for each part, MAWPpart , the thickness must subtract the corrosion allowance: t = 0.12334in 0.07874in = 0.0446in MAWPpart (hemispherical): P = MAWPpart (cylindrical): Circumferential; P = Longitudinal; P = The smallest value of pressure will be chosen. So, the internal pressure for cylindrical part is 32.383 psi. By subtracting the hydrostatic pressure, PH for each part, MAWPpart (hemispherical) = 64.812 psi (0.433)(2.13) = 63.889 psi =440.5 kPa MAWPpart (cylindrical) = 32.383 psi (0.433)(16.01) = 25.451 psi =175.478 kPa The smallest value of pressure is taken as MAWPpart which is 25.451psi. This value is the maximum allowable pressure for the whole vessel.
