Social policy - the rule of law as referring to an ideal condition Essay

Social policy - the rule of law as referring to an ideal condition - Essay Example Since the point is to restrain the coercive activities of government, these general rules should not be framed so as to discriminate either against or in favour of any group of persons known in advance-against Jews or Blacks, for example. Laws against speeding lay down general rules of this kind: they apply equally to all motorists, and they do not single out particular individuals (say, BMW drivers) for special attention. Retrospective legislation is likely to violate the rule of law on this interpretation since its victims and beneficiaries usually can be identified in advance. 1 General rules of this kind that are announced in advance are a defence against the arbitrary actions of governments. They are necessary in Hayek's view both for the proper working of the market and for the existence of liberty precisely because they allow individuals to plan their affairs secure in the knowledge that government powers will not be used deliberately to frustrate their efforts. Once governments go beyond the enforcement of certain general rules, their activities inevitably involve the coercion of particular individuals. ... From this point of view there is no reason in principle why governments should not concern themselves with the regulation of economic affairs. But their interventions should take the form of a framework of laws within which markets can operate, rather than the direction of economic activity by a central authority. 2 Here and elsewhere, Hayek discusses government social and economic policy as if interference with market operations inevitably involves the infringement of liberty. It is not clear why that should be the case. Consider the example raised by Pigou in his review of The Road to Serfdom (Pigou 1944). The wartime practice of directing particular individuals into specific jobs is an infringement of liberty that may be defended for a limited period on the grounds of national emergency.3 This example, the occupational choices of individuals is certainly constrained as a result of government policy. But, from the point of view of those affected, the manner in which they are constrained is no different from the effects of market forces. It seems then that government interference in markets is to count as a coercive infringement of liberty, whether or not it is experienced as such by the individuals concerned. 4 Similar considerations apply to the welfare state. It is entirely proper for governments to be concerned with the welfare of their citizens, provided only that their welfare activities are constrained by the rule of law. The difficulty in discussing 'the welfare state', in Hayek's view, is that the term has no clear meaning. Some of the activities normally included under that heading are unobjectionable and may even 'make a free society more attractive, others are

Michelangelo Essay Example for Free

Michelangelo Essay The artist has painted a portrait of his friends and colleagues. Each one of them is in the prime of their youth, with seemingly no worries. They are all seen having a relaxed time oblivious to their surroundings. There are thirteen people featured in the painting, including two children. The colors in the painting are charming, bringing out the best of the painter and his art. The boat is full of young people having an enjoyable time, drinking and making merry. Life seems to be full of meaning for the people on the boat. The boat seems to be their cup of life overflowing with energy and youth. None of them are worried about the future. Each of the people depicted on the boat are living life to its fullest in the present. They do not seem to be thinking of either the past or the future. Life for them seems to be songs with unending lyrics, going on and on, eternally like the water lapping against the sides of their boat. Michelangelo has not have used color to define his sculptural form. He might have used the different hues of the marble itself to define the sculptural form. In fact, if he had used colors, the sculptures would have lost their natural sheen. It would have made the sculptures look artificial. The sculptures look so magnificent in their natural colors that there is an aura surrounding them that would have been lost with the use of any artificial colors. Color would have faded over time, but the statues have lost none of their sheen, making us believe that there were no colors used anywhere in the statues. The natural glory of the statues has been retained in the centuries gone by because of the natural elements. Their glory remains a testament to the resilience of nature.

Arthur Millers The Crucible Essay -- Essay on The Crucible

Arthur Miller's 'The Crucible' The Crucible, written by Arthur Miller, is a tragic story of injustice suffered by an innocent community who are subjected to the hypocritical, prideful judges of their trial. These Judges use their power to eliminate evidence of their mistakes and return their community to puritanical ways. The leaders of Salem are not concerned with seeking the truth and justice, but with maintaining their authority and reputations; this objective leads them to consistently rejecting truth, against all logic and evidence of their senses. The symbols of truth portrayed throughout the play are exhibited through a handful of innocent hearted characters in the book such as Elizabeth Proctor. Her virtues of dignity and honesty are evident in the ways she calmly argues against Danforth and Hale’s accusations hat she is somehow involved in witchcraft. Although she nearly contradicts herself as a symbol of truthfulness when she lies about John’s adultery; it is very admirable to try to protect her husband, and she understands later when he recants. This is an example of her ability to grasp the wider issues of morality. Rebecca Nurse is the epitome of morality a woman known to have great wisdom and compassion. Her moral character is evident in her adamant refusal to not sign a confession. When Rebecca is brought into the room where John Proctor is about to sign a confession her aura of morality and sensibility moves him to take a stand for integrity and follow...

Cultural Communities Essay -- Sociology, Culture

In this essay, I will argue that to understand a person’s behaviour, ways of life and their development, we need to understand their cultural practices and circumstances of their communities. I will also discuss how this can be done and the implication for this in early childhood education. Rogoff (2003) argues that humans are develops as cultural beings: â€Å"people develop as participants in cultural communities. Their development can be understood only in light of the cultural practices and circumstances of their communities- which also change† (p. 3-4) According to Gonzalez- Mena (2003), understanding cultural differences can be confusing and no one can possibly know all about the culture of every family who might come into early childhood centres. So she questions whether this means that should educators ‘throw up their hand’ and give up rather than seek answers by understanding cultural difference, by exploring its broad themes and organising concepts. Everyone’s activities are from their â€Å"universal social-ecological community. Their social relationships, political influences, historical events, movements, economic situation and cultural background affect their activities† (Prout, 2005, p. 25). Understanding deeply the reasons behind their activities is more important than lightly watching their surface activities. By understanding the reasons behind their activities, one gains more knowledge about another’s ethnic context and is less likely to misunderstand the other’s ethnic life meaning. Whether the activity is an everyday chore or academic performance depends in large part on the circumstances that are routine in their community and on the cultural practices they are used to. An example in the Democratic Republic of Con... ...ment the beliefs and the cultural activities in the individual ways. So, I might avoid activities, which against the child’s family’s culture and beliefs, to the child. In Te WhÄ riki (Ministry of Education [MoE], 1996) under Communication strand: the languages and symbols of their own and other cultures are promoted and protected. The curriculum goal states â€Å"children experience an environment where: they experience the stories and symbols of their own and other cultures† (p. 16). In conclusion, understanding reasons behind people’s activities is more important, because the understanding could help us to suspend our own interpretations and values and beliefs in order to make sense of others actions and culture. As well as this, the accurate understanding about young children, family and community could help me to implement early childhood education better.

Modern Technology Essay

Information technology is playing an increasingly important role in the work and personal lives of citizens. Computers, communications, digital information, software – the constituents of the information age – are everywhere. There is though, a considerable number of people that are really concerned about the changes that modern technology implies, stating that it embodies potential risks to social values, freedoms, and relationships and this is what Sherri Turkle also states in her Forbes magazine article ‘Can You Hear Me Now? . I must agree with Turkle’s point of view that technology, along with all the positive aspects it brought into people’s lives, it also brought loneliness and sameness of lifestyle because of this abusive way people got to use technology nowadays. But as opposed to Turkle’s and millions of other people’s fearful thinking that mankind is developing too intimate relationships with machinery; I would say that this can be absolutely controllable. While it is true that the future of technology is only limited by our imagination, people have to learn that no matter how developed technology might get, the basics of a better life are self-esteem, respect for the others and willingness to self-educate and build up a strong character. According to Dictionnary. com,’ technology is the branch of knowledge that deals with the creation and use of technical means and their interrelation with life, society, and the environment, drawing upon such subjects as industrial arts, engineering, applied science, and pure science’. Commonly, technology can be defined as the science applied to practical purposes. It can be argued that modern technology makes life easier and more dignified for most of people. The first and the major advantage is that medical science is very progressive and vastly available. Without the needed technology a lot of people would struggle with their health. In addition it saves many innocent lives. The point is to spread it and reach with medicine help to the poor nations of the Third World. Secondly, the advanced technology improves industry by making it more effective and, what is vital today, safer for environment. Moreover when we look at TV, personal computer, mobile phone or internet for instance, it is quite obvious that all these inventions have been made in the last 20 years. Thus the speed of improvement is huge and unpredictable. We can get the fastest ways of communication through modern technology which ties humanity together like a nervous system ties the parts of an organism together. Today we are connected with every other human being on the planet in a way people never have been before this leading to globalization through diversity, a very powerful current which is really to consider nowadays. On the minus side there is weaponry which is the inseparable issue of the new technologies. Hence the main problem is the proper use of this knowledge. Nevertheless, weapon engineering propels and provides a huge advance. Also, the industry despite highly developed machinery pollutes the globe. On the other hand while many people live in horrible conditions and famine governments spend a lot of money on developing weapon industry. Is it the right way? Modern technology should prevent social disproportions and not add up even more. Technology entered our lives over a relatively brief period of time with little warning and essentially no preparation. Many who currently use information technology have only a limited understanding of the tools they use and a probably correct belief that they are underutilizing them. This is why most of the people pay more attention first to their interlocutors coming through the modern gadgetry considered a more elevated audience; the ‘real’ ones have come to fill just a second position. This is where Turkle’s fair point comes when she describes these people’s feelings – ‘Being put on pause’ this is the impression we get when the one we are engaged with in a conversation answers his cell phone or replies to an e-mail or a text message. Another example of the modern technology taking over the unprepared people is the virtual lives they build and end up becoming addicted on that up to a certain point where it can even become dangerous for themselves and the ones close to them. Millions become someone else every day, lying about their age, gender, occupation or appearance. If you can be anything, you might as well be who you wish you were rather than what limits you in the real life. So if someone decides they like their online persona better, and decides to spend as much time in that persona as possible, living virtually – are they crazy? These games are addictive by design, and a lot of people get sucked into a virtual world existence, at the expense of their real life happiness. And surely a large part of the attraction is this ability to live an alternate, and in many ways, happier existence. But this can get really dangerous when it comes to children and adolescents as they may discover ‘world in the Second Life’ as Turkle puts it in might be much easier and funnier and they can develop serious issues n forming their character and personalities. And the negative effects technology can have on children are numerous: less physical movement, lack of attraction towards reading, no sense of responsibility. With parents buying their children cell phones and expecting them to call as often as possible showing them actually how little they trust them, this only adds up to children’s developing a lack of responsibility and a sense of dependence, as Turkle puts in and I agree. The time of self-reflection at adolescence is taken over by ‘quickly communicating a state over the cell phone or through an instant message and emoticons’ (Turkle) leading to a new dependence in their early emotional lives. Another point that Turkle makes is that technology leaves less or no time at all to sit and reflect of ourselves uninterrupted and I agree with that. Unless we are really strong as to put away or turn off all the technology around us we cannot get a moment with ourselves as all this machinery can be very distracting. Nowadays, when the rapidness of development and research is so impressive, it is easy to think about the advantages of modern technology. It is obvious that we are close on an era where technology is limited only by our imagination. Therefore the most frequently asked question is: Does technology go the right way and will it save or ruin our civilization? I believe that we can just let ourselves carried along with it or we could impose on ourselves in being more aware of the disadvantages also and try to control it.

Mona Lisa Smiles essays

Mona Lisa Smiles essays The movie Mona Lisa Smile explores life through themes of feminism, marriage, and education lead by a modernist teacher at the end of a traditional era. This film explains the idea or womens liberation, which was about women being able to do what they want, when they wanted to. The thought is that women should be allowed to do anything. Choosing to be a housewife is perfectly acceptable but if a womans dreams go beyond the household than she should be able to act upon them. Issues of questions dealing with uniformity and choosing the path that is right for each individual are also addressed. The film Mona Lisa Smile ultimately illustrates how certain expectations within gender roles, contraception, divorce, and marriage have changed over time, and some have remained the same. The movie begins by introducing the lead character, Katherine Watson, who is a free spirited art history teacher determined to make a difference at the prestigious Wellesley womens college. Very quickly it becomes apparent that Katherine is a non-conformist intellectual with a passion for art and education. Katherines ambition and persistence prove to demonstrate that she is a professor ahead of her time. On the first day to teach class her students attempt to intimidate her by sarcasm and their own intelligence. Katherine leaves the school baffled by the girls unkindness and realizes that she has her work cut out for her. Upon returning home the woman she is living with interrogates her about marriage. Despite her older age, Katherine has never been married which is hard for the women of Wellesley to understand. Katherine upholds marriage and understands the importance of family within society but she is also concerned with her career, helping others, and most of all, happ iness. The women of Wellesley seem to believe marriage is the single most important aspect of a womans life and K...

Raising the Red Lantern essays

Raising the Red Lantern essays This film is a story of something greater than the actual story itself. Set in the 1920s in Northern China, a young girl finds herself involved in something that was not what she had imagined for herself. The main character is Songlian, a 19-year-old Chinese girl, who marries into the Chen Clan only to find herself as one of the four mistresses within a home of tradition and strict order. The geographical setting is appropriate as to the underline theme of the film and that is a feeling of isolation within the walls of the Chen compound. The gray walls of their living quarters strengthens this feeling of isolation experienced by all four women. The only color in their lives is the lighting of red lanterns signifying the sexual wishes of the Master Chen for that evening. The sound effects of bells and Chinese opera serves to enhance the intensity of their longing for real companionship. The relationship between the Master and his four wives is purely sexual. As a result, t he four women compete with one another to sway his affections by conniving and betraying the other for the sake of time spent with the Master. Songlian struggles more than the other wives because she is younger and educated. This is both an asset and a liability for her because the others are very jealous of her and this isolates her even more than the walls. In addition to sharing the Master, each woman including their servants must obey strict rules of the household. These rules act to further control women in an already repressive society of the time. This film is somewhat true to form because women of China especially during this period were very suppressed. Although Chen had wealth, the women were still treated as objects of status without choices or hopes of some kind of personal happiness only sacrifice. This is reinforced by the conversations about the importance of having a son and how having a daughter was considered a wasted birth. ...

Timeline for Applying to Medical School

Timeline for Applying to Medical School Although many students succeed in college despite waiting until the last minute to write papers and cram for exams, applying to medical school requires a great deal of time and an early start. The medical school admissions process is a marathon rather than a sprint. If you really want to win a spot in medical school you must plan ahead and carefully monitor your progress. The timeline below is a guide. Be sure to discuss your aspirations with your academic advisor and another faculty of your undergraduate program to ensure that you are on the right track given your unique circumstances. First Semester, Junior Year: Researching Medical Schools and Preparing for Exams As you enter the first semester of junior year in your undergraduate program, you should seriously begin considering if medical school is the right choice for you. Completing your graduate degree and residency programs are going to require a lot of time, concentration, motivation, and dedication to the craft so you should be absolutely certain this is the career path you want to pursue before investing the money and time in applying to medical school.   Once youve determined that you do want to pursue medicine, you should then determine what a  successful application  entails. Review course requirements and ensure that your transcript satisfies these minimums. You should focus on gaining clinical, community and volunteer experience to boost your application as these will set you apart from other applicants. During this time, it is important that you familiarize yourself with the  application process  and review the resources at the  Association of American Medical Colleges  site to gather information about medical schools. You should also find out how your school handles writing recommendation letters for medical school  as well as how to obtain one. For instance, some programs provide a committee letter written by several faculty members who collectively evaluate your potential for a career in medicine.   Finally, you should prepare for the Medical College Admission Test (MCAT). The MCAT is critical to your application, testing your knowledge of science and basic principles of medicine. Learn about its content and how it is administered.by studying material in biology, inorganic chemistry, organic chemistry  and physics and by investing in MCAT prep books. You may also want to take  practice exams that can help you determine your strengths and weaknesses. Remember to register early if you plan to take the first test in January. Second Semester, Junior Year: Exams and Letters of Evaluation As early as January of your junior year, you can take the MCAT and finish off one portion of your application process. Fortunately, you may retake the test through the summer, but as always remember to register early because seats fill quickly. Its advisable that you take the MCAT in Spring, early enough to allow you to retake it if needed.   During the second semester, you should also request  letters of evaluation  either through a committee letter or a specific faculty who will write a personalized letter of recommendation. You may need to  prepare materials  for their evaluation such as your course load, resumà © and extracurricular involvement on and off campus.   By the end of the semester, you should finalize these letters and your list of medical schools you hope to apply to.  Request a copy of your transcript to ensure that there are no errors and that you have taken the range of courses required by all the programs youve chosen. During the summer, you should begin working on the  AMCAS application. It may be submitted as early as June with the first application deadline August 1 and application deadlines continuing through December. Make sure that you know the deadline dates for the schools you choose. First Semester, Senior Year: Completing Applications and Interviews You will only have a few more opportunities to retake the MCAT as you enter the senior year of your undergraduate degree. Once you have a score youre satisfied with, you should complete the AMCAS application and await follow-up from the institutions where youve applied to attend. If medical schools are interested in your application, they send secondary applications that contain additional questions. Again, take time writing your essays and seek feedback then submit your secondary applications. Also, dont forget to send thank you notes to faculty who wrote on your behalf to thank them but also to subtly remind them of your journey and need of their support.   Medical school interviews may begin as early as August but usually take place later in September and continue  into early spring. Prepare for interviews by considering what you may be asked and determining your own questions. As you get ready for this portion of the application process, it may be helpful to have friends or colleagues give you mock interviews. This will allow you a stress-free (relatively) test of how you might handle the real thing.   Second Semester, Senior Year: Acceptance or Rejection Schools will begin notifying applicants of their application status beginning in mid-October and continuing through spring, depending largely on whether or not you have had or will have an interview yet. If you are accepted, you can breathe a sigh of relief as you narrow your choices of schools that accepted you to the one school you will attend.   However, if you are waitlisted, you should update schools about new accomplishments. It is important during this time to check in on the status a few times throughout the end of the semester and especially in the summer. If on the other hand you are not accepted to medical school,  learn from your experience and consider your options and whether to apply again next year. As the semester and your degree program draw to a close, take a moment to relish in your accomplishments, pat yourself on the back and then select the one school that you want to attend. Then, its time to enjoy the summer - classes  begin as early as August.

Final Exam - Essay Example According to Long, there are many factors that act as sources of power of an administrator, and he claimed that legal authority and budget allocations are not sufficient bases of administration. More so, he claimed that the top hierarchy while structuring administration based on power is not relevant claiming that hierarchical power flows downwards. Long stated that â€Å"the political power flows in from organizational sides and also flows up the organization to the center from the constituent parts† (Stillman 2010, p.107). Therefore, long provided a structure of interests, which to him was an essential factor in determining the scope of possible action. Notably, the administrative power and political power greatly differ; first, the administrative power can be referred to as the ability to cover up the fund embezzlement whereas political power is the ability to order a cover up of embezzled fund. In administration, the power is limited whereas in politics, the power is unlimited due to the decision made by the majority via elections. There are many problems that public administrators face today, some of which include hierarchical order and the flow of power, coping with the expectations of the public, achieving technical competence, and behaving ethically among others. As long stated, the top hierarchy of the administration is not relevant but in reality, power and hierarchical positions truly affects public administrators. Many scholars have argued that power is the most important element in administration and this power is a significant challenge faced by administrators. Secondly, public administrators have trouble in trying to e ffectively satisfy public interest and coping up with the expectations of the public. In addition, public administrators always focus on how to effectively perform the tasks assigned to them by supervisors and

Macro Economics-- Redbox Price Hike Could Dodge Netflix Outrage Essay

Macro Economics-- Redbox Price Hike Could Dodge Netflix Outrage - Essay Example Because the price has increased, it is reasonable to expect that the quantity demanded will decrease. This is because the market demand will adjust to the increased prices by not purchasing the same amount of DVDs as before. However, if demand is high enough, then quantity will remain relatively the same. This is because a competitor, Netflix, raised its prices by even more—60%. Even though consumers may not like the price hike, they may have no other option but to continue using Redbox’s services. I think that Redbox is doing the right thing by raising their prices because they need to make a profit. Because operating costs have risen, it is only natural to pass on that increase to customers. Redbox needs to be aware that its customer base may fall due to this announcement. If so, Redbox needs to decrease its prices marginally so that market equilibrium can be

Supercomputing Exaflop Target Assignment Example | Topics and Well Written Essays - 1000 words

Supercomputing Exaflop Target - Assignment Example Data delivery and correction of errors might reduce the speed of the application despite the superb programming. The GPUs has allows enormous calculations of numbers in parallel as they constitute more cores as compared to the CPUs and current is applied to various data-intensive calculations. The GPUs was originally for tasks that are of graphics such as rendering every pixel in an image. This is because the graphics problem resembles the supercomputing problems (Geller, 16). In the modern world of supercomputing, the GPUs relies on the CPUs for other tasks despite being able to provide the highest calculation power. The speed is not a matter of throwing more cores in the given mix given that it is not easy to avail all the power used in the processing. The data ought to be managed for their proper intake and managing of the outcome. For the data to move appropriately between the CPUs and GPUs and attainment of better performance, the problem has to fit in the GPUs itself. Before th e benefit is attained the speed of the moving data and that of computing are so mismatched and therefore the GPU has to undertake a number of computations (Geller, 16). The Asian researchers are well positioned to the GPUs more parallel supercomputing that is massive. It is believed that economics that favors such innovations may be brought about by China’s isolation from the western influences. This is because of the vendors from the US who holds different perceptions. Whereas the potential bang for the buck is in Asia, if an application works effectively on this kind of accelerator technology, it might turn out to be very cost effective. China’s recent entry into HPC may be of help in this regard. In contrast, it is argued that programmers in more experienced nations may have to undergo re-education (Geller, 16). Historically Hybrid architectures have had an upper hand over the parallelism. They have used less energy than comparable CPU-only systems. The new Top500 l ist showed that the architectural battle over energy efficiency is on. The U.S.’s CPU-based IBM Blue Gene/Q Prototype supercomputer is the most energy-efficient system with the efficiency of 1,680 Mflops/watt. The K Computer consumes enough energy to power nearly 10,000 homes and costs $10 million a year to operate. These costs would significantly increase in an exaflop world. Major changes in the hardware will require major changes in the algorithms and software. Supercomputing is already widely used in fields as diverse as weather modeling, financial predictions, animation, fluid dynamics, and data searches. Each of these fields embodies several applications. While exaflop computers will spawn now-unimagined uses, any current increases in speed as we race toward that goal will greatly benefit many existing applications (Geller, 16).

Survey of Human Resource Management db 3 Essay Example | Topics and Well Written Essays - 500 words

Survey of Human Resource Management db 3 - Essay Example The following discussion focuses on employee retention and how organizations can enhance upward mobility. Organizations should be able to provide a well defined career path for all positions in their organizations. As stated by Shore (2013), organizations can increase their percentage of employee retention by helping their employees envision credible rewards such as salary increment, promotion, performance rewards, and bonuses. This should be available for the junior staff, supervisors, line managers and the top management of an organization. It is important to note that the line managers and top management are the most often affected and may be at risk of leaving because they may feel that their careers have stalled at the present organizations. Well defined career paths can be provided through effective performance management practices where you talk to your employees about their goals and aspirations. Employees inputs serves as a point of departure upon which human resource managers can brainstorm ways to structure job descriptions not only to accommodate employees’ goals and aspirations but also to advance them in a well structured career path. In this regard, attention should be given to alternative career paths that define a more personal employee aspiration since most career paths do not reflect employees’ personal goals. This is not only important in fostering career retention but also important in creating a work environment which promote growth and development (Chhabra & Mishra, 2008). The second strategy for enhancing upward mobility and promoting retention is by fostering skill building through education assistance and cross-training for all employees. Cross training is an important strategy since it helps employees acquire new skills, stay motivated and become more interested in their job. Employees often value opportunities that are available to them

Argument Analysis 2 Essay Example | Topics and Well Written Essays - 750 words - 1

Argument Analysis 2 - Essay Example And in the third and final part, I shall assess the truth and validity of Aquinas’ argument with the help of logical reasoning. I will conclude that Aquinas’ argument is indeed a valid argument for the existence of God, based on its logical structure, but I shall argue that the entire argument is weak for it is founded upon a mere assumption. To begin with, Aquinas starts his argument by observing that there exists an â€Å"order of efficient causes† (â€Å"Summa Theologiae†). So, all events entail the existence of a prior cause, which causes its occurrence. If something is caused, then it must be caused by something other than itself. It must be caused by something other than itself, for it is logically impossible to be the cause and be caused in the same way and in the same respect. However, if something causes another thing’s occurrence, which causes the occurrence of another thing, which in turn causes another, then an order of efficient causes would entail, an infinite chain of causes. There cannot be an infinite chain of causes, for there would be no first cause. The absence of a first cause would entail the absence of a beginning from which all things began to occur. There must exist a first uncaused cause that initiated the chain of efficient causes, which is God. Therefore God exists. Given the aforementioned reconstruction, I began by claiming premise one by referring to the law of causality, which is a given in Aquinas’ argument. In premise two, the first premise is then applied to the occurrence of X, from which it was inferred, by virtue of â€Å"material implication,† that X was caused by something prior to it, that is, Y, as premise three verifies it (Copi and Cohen 395). Premise four applies the same principle, by virtue of material implication, from which it was inferred that Y was caused by something prior to it, that is, Z. However, premise five shows that this order of efficient causes lead to an infinite regress, from which

JPOs are entitled to paid working holidays which includes, but are not limited to, New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Please note that in the occasion that the holiday falls on a Saturday or Sunday, another day off may be substituted, upon approval of the employer. JPOs may also be granted a vacation leave after six months of continuous service has been rendered. The number of vacation leave, however, will depend on the number of years in service, with a maximum of 15 days for those having rendered at least one year of continuous service. JPOs are also entitled to family leaves in cases of giving birth or conception-related cases, adoption, care of new-born child, family illness, child’s medical appointment of parent-teacher conference Health Insurance. All employees are entered in a group health insurance under a health maintenance organization (HMO) as approved by two-thirds of the majority during the General Assembly Meeting. The group insurance will cover hospitalization, health, long-tern disability, and accident expenses. Employer contribution starting January 2007 will be $557 per month. As such, premiums required for maintenance of the insurance, in excess of the employers contribution, shall be deducted by the state treasurer on the JPO’s salary on a monthly basis and upon employee’s written order. Retirement/ savings plan. After achieving five years of continuous service, provided that the employee is 50 years of age, a JPO is entitled to a retirement benefit which will be computed based on the employee’s age of retirement, length of service, and pre-retirement earnings. Employees may opt for a normal or early retirement, the latter, however, will deduct the accrued benefits for the years prior to the normal retirement age. The employee may choose to receive payment of benefits on a straight life annuity where the retiree will be paid on a periodic basis; or lump-sum payment where the retiree will receive the full one-time payment and no further benefits will be given to the employee upon receipt of payment. Other options will be joint-and-survivor annuity where benefits are provided for married participants. The amount of survivor annuity shall be between 50-100% of the amount payable for the time the couple is alive. The amount, however, will be lower than that received from straight life annuity. In cases where an employee become totally disabled or ill prior to his eligibility in the retirement plan, but has served the company for 10 consecutive years, he will be entitled for a disability retirement benefit, which he could defer or immediately claim. Life insurance. In cases of death or dismemberment of employees, they will be entitled to a life insurance benefit which will be paid in lump sum following the multiple-of-earnings formula. Using this formula, the length of service and earnings of the employee will be incorporated in the computation and will therefore increase following an increase in employee’s salary. Provisions for the life insurance includes accidental death and dismemberment benefits to the employee or his beneficiary equivalent to the basic life insurance and a percentage of the life benefit for dismemberment; monthly income to surviving family members of the employee; retirement from work; and reduction of life insurance for employees near or above 65 years.

The Block Cave Mining Method

The Block Cave Mining Method Block caving is a large-scale underground mining method applicable to the extraction of low-grade, massive ore bodies. With the amount of literature available on block caving this report identifies the need to provide a simple understanding of the process. Understanding a production process of a block cave mine is an important aspect before getting involved with technical aspects of the mine. This report attempts to give an introduction into the production process of a block cave mine and also an understanding about block caving. The document has been split into four chapters, Chapter One gives a basic understanding of the method and highlights the considerations that have to be made before the implementation of a block cave mine. Chapter Two gives an introduction into the production process involved in a block cave mine by taking into account four major levels involved in production. The production process has been described in the form of a flow chart for simple understanding of the process. Chapter Three outlines the significance of production control and production management in order to increase productivity of the mine. Chapter Four outlines some of the safety and risks involved in a block cave mine and the necessary precautions to be taken in order to increase safety. This report has been intended to provide a simple understanding of the block cave mining method and the production process involved. This report is advocated towards a layman in block caving in view of getting an impression about the block cave mining method. Chapter One Introduction 1.1 Block Caving Block caving is an underground mining method applicable to the extraction of low-grade, massive ore bodies with the following characteristics: large vertical and horizontal dimensions, a rock mass that will break into pieces of manageable size, and a surface that is allowed to subside. These rather unique conditions limit block caving to particular types of mineral deposits. Block caving is used for extracting iron ore, low-grade copper, molybdenum  deposits, and diamond-bearing kimberlite pipes. 1.1.1 Block Caving Method A large slice of material is blasted at the base of the ore body which creates an instability within the orebody, inducing the breakdown and mobilization of ore to the production level through the breakdown of ore and waste due to the natural pattern of breakages, development of stresses in the active caving area, and the low strength of the rock mass. The size and shape of the undercut depends on the characteristics of the rock mass. Excavations are created at the production level at base of the orebody to draw out the broken material. A large amount of development expenditure is required to set up the facilities to break the lowest level of the ore body, and all the broken rock is extracted out of the block cave through a system of drawbells. Once the caving is initiated, operating cost of the block cave is very low comparable to the operating costs in open pit mining. Once caving is initiated, production can be ramped up until the production rate is almost equal to the caving rate. The undercut is advanced in the horizontal plane to create greater areas of caving for increasing the production.   Rock breakage occurs only in the caving areas, induced by undercutting, and has low drilling and blasting cost; some amount of blasting may be required at the drawpoints1  to break some of the large rocks coming through the drawbell, especially during the initial stages of draw. Most block caves these days are highly mechanized with large number of large LHDs (load-haul-dump machines) working at the lower levels, though smaller orebodies can also be caved and extracted using gravity draw systems with orepasses2  and slushers3. The development of a conventional gravity flow system of block caving involves Figure Conventional Gravity Flow System http://technology.infomine.com/reviews/BlockCaving/assets/images/BlockCaving1.jpgSource: Infomine Block Caving A spot where gravity fed ore from a higher level is loaded into hauling units A vertical or inclined passage for the downward transfer of ore A mechanical drag shovel loader an undercut where the rock mass underneath the block is fractured by blasting; drawbells beneath the undercut that gather the rock into finger raises4; finger raises that draw rock from drawbells to the grizzlies; a grizzly level where oversized blocks are caught and broken up; a lower set of finger raises that channel ore from grizzlies to chutes for train loading the finger raises are arranged like the branches of a tree, gathering ore from a large area at the undercut level and further channeling material to chutes at the haulage level; and a lowermost level where ore is prepared for train haulage and chute loading. When LHDs are used, the development required is considerably less complex and involves Undercut Levelhttp://www.edumine.com/xcourse/xblock101/docs/figures/images/10002x.jpg Extraction LevelSource: Infomine Block Caving 4 Steeply sloping openings permitting caved ore to flow down raises through grizzlies to chutes on the haulage level an undercut where the rock mass underneath the block is fractured by blasting; drawbells constructed between the undercut and extraction levels; an extraction level with drawpoints at the base of drawbells; and an ore haulage system to collect, crush and transport the ore out of the mine.

The levels that have been taken into account here are Extraction Undercut Haulage Ventilation In a natural progression of a block cave mine the infrastructure that need to be built before the start of caving includes Primary access to the production levels (ramps and shafts) Extraction level excavations Haulage and Ventilation level excavations; and Crushing and ore transport facilities. While most of these excavations need to be created before the start of caving operations, construction of some extraction, haulage and ventilation level drifts can be planned just in advance of actual caving operations. Each of these levels is given a brief introduction and the production process for each level are outlined from collecting data from different sources. The information flow in the form of a flow chart is provided for ease of understanding the process. The information flow chart provided is implemented from personal experience and its objective is to provide an impression on the production process of an underground block cave mine. 2.2 Extraction Level The extraction level is the main production level in a block cave operation. All the ore from the block cave is drawn through draw points at the extraction level and then transferred to haulage level through a system of ore passes or a fleet of LHDs. Since this is the main production level, it is developed and supported to counter the stresses and displacements that can be expected during the life of the drawpoints at the level. The arrangement of drawpoints, drawbells and other excavations on the extraction or production level is referred to as the extraction level layout. The development of the extraction level and the drawbells creates two types of pillars. The major apex is the shaped structure or pillar above the extraction level formed between two adjacent drawpoints but separated by the extraction or production drift. The minor apex is the shaped structure or pillar formed between two adjacent drawbells on the same side of the extraction drift. The drawpoint spacing, the drawpoint width, and the distance between the undercut and extraction levels are all designed based on the fragmentation expected within the block cave. The ground support installed in the excavations at the extraction level is based on the characteristics of the rock mass and the expected stress levels at different locations. 2.2.1. Drawbells The ideal shape of the drawbell is like a bell, so that ore can flow to the drawpoint. However it is a compromise between strength and shape. The major and minor apexes must have sufficient strength to last out the life of the draw. It needs to be established how much influence the shape of the drawbell has on interaction. It has always been an empirical point that shaped drawpoints improve ore recovery as the ore should have better flow characteristics than a drawbell with vertical faces and a large flat top major apex. The time consuming operation is creating the drawbell. The undercut technique also determines the shape of the major apex and importantly the shape of the drawbell. The draw rate from the drawbells is an important factor in that it must provide space for caving; also it must not be too fast to create a large air gap and possible air-blasts. If the draw rate is too fast seismic activity will occur. Production must be based on this value and not rely on economic factors such as short term return on investment that ignores long term consequences. There is also the fact that a slow draw rate will mean improved fragmentation. 2.2.2 Extraction Level Production Process Planning Design Equipment/People Decision Making Ground Support Drawbells Drifts Ground Support Development Pathways Ventilation Ventilation Blast Hang ups Drawpoint Undercutting Secondary Blasting Ore Removal LHDs Ore pass full Ore Pass Haulage Level Secondary Ore pass Crusher 2.3 Undercut Level The process of undercutting creates instability at the base of the block being caved. Block cave mining is based on the principle that when a sufficiently large area of a block has been undercut by drilling and blasting, the overlying block of ore will start to cave under the influence of gravity. The process will continue until caving propagates through the entire block surface or to the open pit above, unless a stable shape is achieved. The purpose of the undercut level is therefore to remove a slice of sufficient area near the base of the block to start the caving of the ore above. The undercut level is developed at the base of the block to be caved. The caving of the block is initiated by mining an undercut area until the hydraulic radius of the excavation reaches a critical value. As the broken ore above it will collapse into the void so created. Vertical propagation of the cave will then occur in response to the continued removal of broken ore through the active drawpoints. The horizontal propagation of the cave will occur as more drawpoints are brought into operation under the undercut area. 2.3.1 Undercutting Undercutting is the most important process in cave mining. As not only is a complete undercut necessary to induce a cave, but the design and the sequencing of the undercut is important to reduce the effects of the induced abutment stress. It is essential that the undercut is continuous and it should not be advanced is there is a possibility that pillars will be left. This rule which is often ignored owing to the problems in re-drilling holes, results in the leaving of pillars resulting in the collapse of large areas and consequent high ore losses. The undercut technique also determines the shape of the major apex and importantly the shape of the drawbell. Care must be taken that there is no stacking of large blocks on the major apex as this could prevent cave propagation. 2.3.2 Undercutting Techniques Conventional The conventional undercutting sequence is to develop the drawbell and then to break the undercut into the drawbell. Henderson Technique The Henderson Mine technique of blasting the drawbell with long holes from the undercut level just ahead of blasting the undercut reduces the time interval in which damage can occur. They have also found it necessary to delay the development of the drawbell drift until the drawbell has to be blasted. Advance Undercut The advance undercut technique means that the drawpoints and drawbells are developed after the undercut has passed over, so that the abutment stresses are located in the massive rock mass with only the production drift. 2.3.3 Undercut Level Production Process Design Planning Development Equipment/People Decision Making Ground Support Ventilation Drifts Pathways Undercutting Ore Removal Haulage Level LHDs Crusher Muck Removal LHDs Ore Pass Waste Dump 2.4 Haulage and Ventilation Level The haulage and ventilation levels lie below the extraction level. They need to be developed with adequate excavations to handle the quantity of broken ore and ventilating air streams required for the designed production rates, equipment and manpower employed within the block cave. Facilities for storing, crushing and conveying the broken ore to the mill need to be developed at the haulage level. The larger excavations required for the crushers, ore bins and conveyor transfer stations need to be located outside the zone of influence of the stresses due to the block cave, and adequate ground support will need to be installed to ensure that the excavations are stable during their expected life. The excavations and levels must be placed far enough apart so that there is limited interaction between numerous excavations created to move the ore from the production level to the milling facilities at the surface. 2.4.1 Haulage Level Much of the development of the infrastructure for a block cave operation is completed during the pre-production stage though some haulage lines and ventilation drifts and raises may be deferred to later in the life of the block cave. Scheduling the development of haulage and ventilation drifts needs careful planning so that the required facilities are in-place well in advance of their requirement. Though there is some flexibility in the development of these levels since they are different elevations and lie below the extraction level, the preliminary layouts need to be prepared so that the flow of materials, ore and ventilating air can be integrated without interruption as the block cave progresses. 2.4.2 Ventilation Level Ventilation Levels are normally developed between the haulage and the extraction levels. During the development phase air is streamed through the undercut and extraction levels to the working faces and exhausted through the raises to the ventilation level. During production, air is coursed through the extraction level and exhausted through the ventilation raises to the exhaust side of the ventilation level. Additional air is provided at the working areas through ventilation raises which connect to the intake of the ventilation level 2.4.3 Haulage Level Information Chart Scoop Ore Removal Haulage Level Haul Distance Optimization LHDs Crusher Figure Haulage Level Information Chart 2.4.4 Ventilation Level Information Chart Auxillary Ventilation Intake Raise Exhaust Raise Fresh Air Exhaust Air Drifts Pathways Fans/Vent Ducts Chapter Three Production Control 3.1 Departments in a block cave mine involved in Production Control Design Planning Geology Geo-technology Ventilation Maintenance Cave Development/Production Survey Construction Electrical Mechanical Human Resource Safety In a Mine Environment each and every department plays a crucial role to keep the Mine running and to meet the production targets. Problems associated with these departments no matter how small they may be contribute damage in their own way to dampen the production. Production planning for block cave operations can be complex. The factors to be considered include geotechnical constraints, cave shape, draw point development sequence, draw point productivity, production block limits such as loader capacity and ore pass capacity and variable shut-off grade mining costs. The nature of the problem also changes during the life of a cave from initial production build up to final closure. Overall objective for production planning should be to maximize productivity, some of the aspects of production planning include Minimum/Maximum tonnage per period Maximum total tonnage per draw point Ratio of tonnage from current drawpoint compared with other drawpoints. Height of draw of current draw point with respect to other drawpoints Percentage drawn for current draw point with respect to other drawpoints Maximum tonnage from selected groups of drawpoints in a period. 3.2. Production Control Major Concerns 3.2.1 Fragmentation Rock fragmentation is the fragment size distribution of blasted rock material, in caving operations fragmentation has a bearing on Drawpoint spacing Dilution entry into the draw column Draw control Drawpoint productivity Secondary blasting/breaking costs Secondary blasting damage Primary Fragmentation Caving results in primary fragmentation which can be defined as the particle size that separates from the cave back and enters the draw column. The data to be considered for the calculation of the primary fragmentation is In situ rock mass ratings Intact rock strength Mean joint spacing and maximum and minimum spacing Orientation of cave front Induced stresses Secondary Fragmentation Secondary fragmentation is the reduction in size of the primary fragmentation particle as it moves down through the draw column. The processes to which particles are subjected to, determine the fragmentation size distribution in the drawpoints. The data to be considered for the calculation of the primary fragmentation is The effect of fines cushioning Draw strategy and draw rate Rock block strength Shape of fragments Frictional properties of fragments Column height Fragmentation is the major factor that determines productivity from a drawpoint. Fine material will ensure high productivity. 3.2.2 Draw control Draw control is one of the major concerns that need to be optimized in order to increase productivity of the mine. Geomechanical issues related to draw control have played a dominant role in efforts to reduce stress and improve fragmentation and reduce dilution. Draw control is the practice of controlling the tonnages drawn from individual drawpoints with the object of Minimising dilution and maintaining the planned ore grade. Ensuring maximum ore recovery with minimum dilution. Avoiding damaging load concentrations on the extraction horizon. Avoiding the creation of conditions that could lead to air blasts or mud-rushes. The following have to be considered for draw control strategy in order to maximize productivity, Any factors observed during the start of caving that will influence the planned caving and drawdown processes. Control the draw from the first tonnage into the drawpoint. Define the potential tonnages and grades that will be available from each drawpoint. The draw control system must be fully operational. Confirm that the planned draw strategy is correct. The recording and analysis of the tonnages drawn, this important aspect is often not treated with the required respect. Managing the draw by following the adopted draw strategy. Define how the control is to be monitored, maintained and audited. Planning for how the draw column would behave with time. An estimation of the remaining tonnages and grade for future production scheduling and planning. Personnel must be aware of the definition of isolated drawpoint. Ensure the drawpoints are clearly and correctly identified underground. There must be reporting system to record and describe why allocated drawpoints have not been drawn. Ensure secondary breakings are done effectively and efficiently. Develop standard procedure for close drawpoints. Draw control is what block caving is about, the reasons for and the principles of draw control must be clearly understood by all operating personnel. Preparation of orebody must be done in a sound way so that preventable problems do not hamper the draw control. 3.2.3 Secondary Breaking Irrespective of the method of primary blasting employed, it may be necessary to reblast a proportion of the rock which can then be handled by the loading, hauling and crushing system. There are four types of problems that cause a need for secondary breaking, High hang-ups are where a large fragment lies across the entrance to the draw bell up to 19m above the footwall. This type of hang up is very rare though, and it is more common that this will only occur up to a distance of 5 m above the draw point floor. Rock jumble is where several ore fragments of rock smaller than two cubic meters form an arch in a drawbell. This is found to occur especially in the troat of the drawpoint. Low hang up is a large fragment of over two cubic metres hanging in the troat or on the floor of a draw point clocking the flow of ore. Draw point oversize is any large fragment over two cubic metres on the floor of a draw point and effectively prevents loading by LHDs. Some of the techniques that are in use for secondary breaking are as follows, Concussion blasting Drill and blast Emulsion secondary blasting Robust hydro fracturing breaking system There are many products on the market today that promise effective secondary breaking of both hang-ups and boulders, including cone packs, the quick draw system, the boulder buster and the penetrating cone fracture technique. In order to choose a secondary breaking method with respect to productivity the following need to considered and evaluated, Explosive quantities Labour and Equipment requirements Fragmentation Safety 3.3 Significance of Production Management

Kettering :: essays research papers

Kettering Tape   Ã‚  Ã‚  Ã‚  Ã‚  In listening to Kettering’s lecture there are five main points that I was able to pick out: 1.  Ã‚  Ã‚  Ã‚  Ã‚  Point of view of failure – The example he gave was that a person going to grades K – 12 take several tests and if they fail just one they are out, however inventors can fail 999 times but if they succeed just once then they are a success not a failure. 2.  Ã‚  Ã‚  Ã‚  Ã‚  There are two kinds of education – Kettering claims that one kind of education is being specialized in one particular subject, and the second form of education is knowing a little bit on a wide variety of subjects. This second form is what Kettering claims to be how inventors were educated. 3.  Ã‚  Ã‚  Ã‚  Ã‚   I.Q. Tests – Kettering claimed that I.Q. tests have nothing to do with the person taking the test, but rather, what the person administering the test wants them to be. 4.  Ã‚  Ã‚  Ã‚  Ã‚  Teach kids the future – We are going to spend our time in the future not in the past, so why do we not study the future and study what is going to happen rather than what has already happened that we cannot change. We should educate people for the next 15 – 20 years. 5.  Ã‚  Ã‚  Ã‚  Ã‚  The â€Å"problem† – Kettering states â€Å"The ‘Problem’ has to be the ‘boss’.† From what I get of this he means that you have to come up with a resolution from the problem. The problem has to be the main focus for a reasonable solution to be approached. What do I think of what Kettering said? Where is he right? Where is he wrong? Why?   Ã‚  Ã‚  Ã‚  Ã‚  I cannot say that I agree totally with what he says, but then again I cannot say I totally disagree. He brings up several points that are infinitely arguable. I do agree with the two kinds of education that are stated in number two above. I don’t think there is one best way to teach children wether it be specialized in one subject, or in a wide variety of subjects as each child learns differently and at their own pace.   Ã‚  Ã‚  Ã‚  Ã‚  I don’t think that we can teach children or adults the future.

Real World Connection

Real World Connector In the chapter Church, I felt a connection with Kiowa. â€Å"Not a minister,† he said, â€Å"but I do like churches. The way it feels inside. It feels good when you just sit there, like you’re in a forest and everything’s really quiet, except there’s still this sound you can’t hear†. The way I relate to this part is the same way I feel when I go to a temple (similar to a church) I feel the same way. When I go to the temple I sit there and listen to the prayer. But when I get into the prayer, everything goes quiet.I get this really good feeling inside myself. All my fears are taken over by peace. I think that’s why Kiowa says this is â€Å"just wrong† to be inside a holly place. One thing I didn’t understand the monks cleaning the solider weapons. Was there so representative of this. I know in my temple the minister is not allowed to touch weapons. Overall, a temple or a church are both religious place , but are both peaceful places. We are supposed to feel save in a place or worship. Henry Dobbin tells us about how he liked the whole idea of being a minister. â€Å"I was a kid.The thing is, I believed in God and all that, but it wasn’t the religious part that interested me. Just being nice to people, that’s all. Being decent†. The teaching of any church or temple are the same. God tells us to be good humans, and give back to the community. I agree and disagree with Henry Dobbins. I agree with him to the part about being a nice person. I disagree with the part when he says â€Å"it wasn’t the religious part that interested me†. The reason I disagree with this is because reglion should about be an interest not only the lessons of God. Maybe I misunderstand what Henry Dobbin was saying.

Serial Killers in Modern America

In today’s society, America is a dangerous place for people to walk alone. We have definitely had our share of serial killers over the years. We have had the Harpes brothers in the 1800’s to the more modern day Jeffrey Dahmer. A serial killer in the United States is defined by Congress as â€Å"someone who murders a minimum of three or more people. † (Harris) Three-quarters of the world’s total serial killers have done their killing in the United States. True crime writers often claim that America’s first serial killer was H. H.Homes, but there were actually several before him. The first documented serial killers were two brothers named Micajah and Wiley Harpe. These two killed people for two reasons and they were for fun and profit. These two were notorious for their cut-throat ways, and the other outlaws were scared of them. (Ramsland) They terrorized the Natchez Trace which is known today as the Natchez Trace Parkway. Not much is known about the early history of the Harpes’, but they terrified everyone they came across. The Harpes even slaughtered two of their own children each. Ramsland) For a brief period of time the Harpes traveled with a group of river pirates who were merely concerned with enriching themselves. As you can imagine they did quite well at that. However, these pirates never intended for any physical harm to come to their victims, but the Harpes had other intentions. The incident that caused the Harpes to be kicked out of the group was when they tied a naked flatboat passenger to a blindfolded horse and sent it over a cliff. (Ramsland) From this point on that group of pirates referred to the two as â€Å"men turned into wolves. †Micajah Harpe admitted to a number of murders, but he said that there was only one that he was remorseful for, and that was the murder of his own child. His reason behind killing his own child was because the baby’s crying annoyed him. (Ramsland) Micajah would e nd up being killed by a pack of wolves, and Wiley was hung on February 8, 1804. The first documented serial killer was H. H. Holmes which made his mark on the 19th century by committing over 27 murders. (Kade)He was born, Herman Webster Mudgett in 1861. He started off as a very unruly child who enjoyed being cruel to animals. He would do most of his killing his hotel that was icknamed Murder Castle. The actual name of this hotel was never recorded. He used an advertisement to lure people that were going to attend Chicago’s World Columbian Exposition in 1893. Back in those day lodging was a hard thing to come by, so this allowed Holmes all the victims he wanted. His preference was blond females that he put through torture rituals. He would brutalize them and then incinerate them. He even sold some of the skeletons of his victims. No one ever suspected anything from him, because he had charm and good looks. It was until after Holmes’ execution that investigators would le arn more about what he had done.Some of the victims were locked up in soundproof rooms that had gas lines that would allow him to asphyxiate any victim at any time. (Kade) There were also some locked in a large soundproof bank vault and suffocated to death. Holmes was even quoted saying, â€Å"I was born with the devil in me. I could not help the fact that was a murderer, no more than the poet can help the inspiration to sing. I was born with the â€Å"Evil One† standing as my sponsor beside the bed where I was ushered into the world, and he has been with me since. † Now we fast forward to 1974 when women were vanishing from college campuses around the Washington and Oregon area.There was a 21 year old radio announcer named Lynda Ann Healy that was among the ones that went missing. Then in July of 1974 two women were seen wondering off with Ted towards his sailboat and were never seen again. Around this same time there was a grave yard of bones discovered in a Washingt on forest that would later be identified as some of the women that had went missing in the Washington and Utah areas. It was then that investigators from both areas were able to come up with a profile and a sketch of the man named Ted. (Montaldo)In August of 1975, Bundy was stopped for a driving violation, and when the officers searched his car they found a number of items such as, handcuffs, crowbar, and pantyhose with eye holes cut in them. He was then arrested on suspicion of burglary. Upon further examination of the things found in Bundy’s car the police realized that they matched items that one of the girls he attacked described seeing. This same girl identified the handcuffs as the ones that were fastened around one of her wrists and she picked him out of a line-up. Bundy then went to trial for the attempted kidnapping of Carol DaRonch in February of 1976 and was found guilty.For this case he was sentenced to 15 years in prison, and in October of 1976 he was charged wit h the murder of Carolyn Campbell. Bundy was extradited from Utah to Colorado for the trial. He would then be his own lawyer, which gave him a little freedom to move around the courtroom and the law library that was inside of the courthouse. In June of 1977 during his pre-trial hearing Bundy escaped by jumping out a window in the law library, only to be captured a week later. This would not be the end of Bundy’s escapes either. He did it again on December 30 and made it to Tallahassee, Florida.He got himself and apartment near the university using the name Chris Hagen. (Montaldo) He paid his way at a local college bars with stolen credit cards and when he got bored he would sneak into the lecture halls just to listen. On January 14 Ted Bundy would break into a Chi Omega sorority house and kill two women, and brutally raped one of them. He even beat two other women that managed to survive. The reason that they survived was because their fellow roommate came home. At around 3 a. m. Nita Neary came home and saw that the door was open, and as she entered the house she heard footsteps upstairs. Montaldo) She then went upstairs to find two of her roommates dead and the other two were severely beaten. Later that night another woman would be attacked, but the police would find a mask on her floor that would match the one found in Bundy’s car later. In February of 1978, Bundy kidnapped and mutilated a 12 year old girl named Kimberly Leach. Bundy was arrested again within a week of her disappearance for driving a stolen vehicle. Witnesses were able to place him at the dorm and at Leach’s school. There was also physical evidence that would link him with the murders.Among this evidence was a mold that was made from the bite marks found on one of the victims. Bundy went on trial in 1979 for the murders that happened at the sorority house and was found guilty. He received two sentences for death by electric chair. Then in January of 1980 he would go to t rial for the murder of Kimberly Leach. He actually had lawyers for this case and they tried going for an insanity plea. Bundy called Carol Boone as a character witness and even married her while she was on the witness stand. He called her as a witness because she believed in his innocence, and would later give birth to a little girl that Bundy adored.They were later divorced after she realized that he had actually done all the crimes he was accused of. Ted Bundy died on January 24, 1989 at 7:13 a. m. So why did all these people do what they did? Obviously that all had some reason for doing it and Ted Bundy said that his reason for doing it was because of all the pornography that he was subject to at such a young age. Other serial killers like Jeffrey Dahmer blamed it on being born with a part of him missing. John Wayne Gacy claimed that his victims deserved to die.One would have to think that they were insane for doing what they did, but most of them are rational and calculating pre dators. (Scott)I think that Denis Nilsen, the British version of Jeffrey Dhamer, put it best when he said, â€Å"a mind can be evil without being abnormal. † References Bibliography Harris, William R.

Literary criticism

Literature represents a language or a people: culture and tradition. But, literature is more important than just a historical or cultural writing. Literature introduces us to new worlds of experience. We learn from books and literature; we enjoy the triumphs and the tragedies of poems, stories, and plays; and we may even grow through our literary journey with books. In conclusion, we may discover meaning in literature by looking at what the author says and how he/she says it. We may interpret the author's message. However we interpret literature, there is still an artistic quality to the works.Literature is important to us because it speaks to us, it is both universal and individual, and in many ways it affects us, for the better. When some people think of the word â€Å"Literature† they think of books like, Walden, Old man and the Sea, Tom Sawyer, Great Expectations, or Moby Dick. These are what some call â€Å"the classics. † While these few books are indeed literatur e do we subconsciously judge other books based on the styling’s of these few? People believe that the true meaning of â€Å"Literature,† is a literary work in which the readers mind is opened to new concepts and ideals.For a writing to be called â€Å"Literature† it doesn’t have to be considered a â€Å"Classic† nor does it need to follow the same construct as these so called â€Å"Classics†. The book, 11/23/63, is much more of a form of â€Å"Literature† than A Tale of Two Cities. Based solely on the fact that in the Stephen King novel, he places the thought of, â€Å"What if? † into your mind.. Whereas, â€Å"A Tale of Two Cities†, depicts the plight of the French peasantry in the years leading up to the revolution, as opposed to opening your mind. While A Tale of Two Cities, shows you what life was like in those times.Stephen King shows you an alternate universe in which there was but one change, and how that one chan ge affects how history takes its course. When the author helps your mind, explore worlds of endless possibility, or sheds light on a new way to perceive things. That is when the author has created a â€Å"True† work of literary merit. The thing about the term, â€Å"Literature†, is that it doesn’t have just one meaning. Literature is comprised of many things, but while Webster definition of â€Å"Literature† is, â€Å"the production of literary work especially as an occupation.† The â€Å"True† meaning is open to interpretation, meaning that one person’s definition of the word may be completely different than another person’s definition. This is both the great and horrid thing about the term. When scholars classify writing as literature, they often consider it a book or writing that has stood the test of time and despite its age it has surpassed many other great works through history by receiving merit from the scholars, based on their description of the word, influential.You may agree that it should be considered a piece of â€Å"Literature†, if it has done this, and you would be right, but what if it was a great piece of literary art that didn’t become a best seller? And thus was cast into the abyss to be forgotten until stumbled across one day by a mind ready to take in what the author wanted to say. Would you consider it â€Å"Literature? † Or would you just leave it in the abyss because it never became a best seller? Take Moby Dick for example, it is considered to be one of the Great American Novels and a treasure of world literature. However, it never received enough credit to title it a â€Å"Best seller.† One literary work, also helps define my idea of the word Literature, is The Hobbit by J. R. R Tolkien. The reason I consider this a piece of â€Å"Literature† is because of the amount of imagery Tolkien uses to bring his world to life in the imagination of the r eader. In this excerpt from that book, he describes every thought of the characters and his use of imagery helps create the scene in the mind of the reader. â€Å"The dark came into the room from the little window that opened in the side of The Hill; the firelight flickered-it was April-and still they played on, while the shadow of Gandalf’s beard wagged against the wall.The dark filled all the room, and the fire died down, and the shadows were lost, and still they played on. And suddenly first one and then another began to sing as they played, deep-throated singing of the dwarves in the deep places of their ancient homes; and this is like a fragment of their song, if it can be like their song without their music. † (The Hobbit, Page 15) Tolkien’s powerful use of imagery in that passage painted a clear picture of what happens while the dwarves sing. However, Splatterpunk also uses powerful imagery to paint pictures.The key difference between the imagery used Spl atterpunk and the imagery used in The Hobbit, is how the imagery is used. In the novel, The Cipher, which combined intensely poetic language and lavish grotesqueries, the author, uses imagery to place the pictures into the mind of the reader using powerful and descriptive words. As opposed to Tolkien, who draws upon the reader’s imagination with basic descriptions to help create a sketch in his mind. Now, many would not consider this a form of â€Å"Literature† due to the lack of personal connection between the story and the reader.However, I consider this book, and even this passage alone, to be a form of â€Å"Literature† solely because it opens my mind to a new world full of adventure and intrigue, while keeping the reader glued to the book during the time he reads. Imagery is a powerful tool for both the author and the reader, for if the author isn’t clear with his use of imagery it breaks the reader’s attention and allows him to be lost within the story, and not in a good way. Tolkien also uses diction to place an image into the readers mind, and he does this in such a way the reader begins to sing the song in his own head.Far over the misty mountains cold To dungeons deep and caverns old We must away, ere break of day, To claim our long-forgotten gold. Goblets they carved there for themselves And harps of gold; where no man delves There lay they long, and many a song Was sung unheard by men or elves. The pines were roaring on the height, The winds were moaning in the night. The fire was red, it flaming spread; The trees like torches blazed with light (The Hobbit, Page 16) Literature is important to us because it speaks to us, it is both universal and individual, and in many ways it affects us, for the better.In ways we sometimes may never understand. Ultimately, we may discover meaning in literature by looking at what the author says and how he/she says it. We may interpret the author's message in one way, while someone else finds the message a different way. In this way we see how the definition of â€Å"Literature,† is subjective to both the readers own interpretation, and the overall meaning of the work. Because even when it is ugly, literature is beautiful. Sources Cited Tolkien, John R. R. The Hobbit. N. p. : George Allen & Unwin, 1937. 15. Web.

Machiavelli in practice Essay Example | Topics and Well Written Essays - 500 words

Machiavelli in practice - Essay Example The success of the quote will be looked at as well. â€Å"A man who is used to acting in one way never changes; he must come to ruin when the times, in changing, no longer are in harmony with his ways.† This quote means that some rulers are stubborn. They feel that their way has worked for years. Their way is right. However as the world changes the ruler is disposed due to his unwillingness to change. Whether a country changes politically, economically, territorially, or otherwise a ruler must be able to rule the changed country. If the ruler does not change to meet the new challenges, the ruler will be overthrown. An example from history about a man never changing is Adolf Hitler. Adolf Hitler came to rule Germany during an economic crisis. His policy of a greater Germanic race had an underlying policy of war. Hitler wanted to rule Europe as a pure Aryan race with the Slavic peoples as slaves or dead. When the war begin going against Hitler, he refused to change his policies. Hitler could have surrendered, but he did not want to. His vision of conquering Europe blinded him. If he would have changed, Hitler might not have eventually been defeated. Saddam Hussein is another example of a man unwilling to change. Hussein ruled Iraq with an iron fist. Iraqis that opposed him were put to death or tortured. Hussein invaded Kuwait. Hussein’s goal was to rule Iraq with an iron fist. After the first Gulf War, Hussein was placed under a monitoring system through NATO. He defied the order over and over. Nothing happened for turning away NATO inspectors or continuing down the path he was on. However, after 9/11 the threat of a nuclear Iraq was intolerable to the United States. It was not true, but even the appearance of the threat was unbearable. Hussein did not change with the times. He kept baiting the United States. As a result America invaded Iraq. Hussein was eventually

The relationship between United States and Israel and its effect on Research Paper

The relationship between United States and Israel and its effect on other Middle Eastern countries - Research Paper Example The liaison between Israel and the United States is one of the most unstable and contemplated relationships in world history. From the period since its establishment in 1948 to today, Israel has faced up to eight diverse American presidents, and eight different outlooks toward Israel as a state, how the U.S.-Israeli relationship should be dealt with, and the issue of Palestine and its people. The relationship between the United States and Israel in the past six decades can be segregated into two schools of thought: the â€Å"special relationship paradigm† and â€Å"national interest orientation† stated Professor Robert Lieber of Georgetown University, an expert on US-Israeli relations . The United States was the first country to recognize Israel as an independent State because at the time in 1948, and until today, the U.S. Government presumes that it shares certain common values and political aims. Under the special relationship paradigm, which forms the basis of U.S. s upport of Israel even today, the Truman Administration sensed that Israel, like the U.S., held a revolutionary fortitude, was compiled of a diverse societal symphony, and shared its democratic ideals. The national interest orientation transpired over time and included mutual aims such as extenuating the Arab-Israeli conflict, sustaining Western access to Middle Eastern Oil, the battle against Islamic Fundamentalism, and with Israel in place, the U.S. was assured continued influence in the Middle East. Definitely, the initial support of the U.S. for Israel was not all politically motivated rather they were initiated on the basis of moral, cultural, and religious sentimental grounds stemming from the mayhem committed in Europe during the Holocaust, which resulted in the major immigration of Jews to Jerusalem and the surrounding areas in the first place (Ben-Zvi 2009). The period from 1948-1957 forms the first phase in the history of U.S.-Israeli relationship. As stated before, the Uni ted States was the first nation to give de facto recognition to the State of Israel primarily on grounds of moral obligation and geo-strategic concerns. This unambiguous assertion of support gave birth to a lifetime relationship between the two countries. However, in these starting years, the United States’ faith in Israel was low, and they were not provided any assistance in monetary or military form. The primary reason of U.S. for making Israel its ally during this period was that in the midst of the Cold War, Israel stood alone as the solitary supporter of the West and discourager of communism in the Middle East. The Truman Administration called this approach an eccentricity of the modus operandi, or method of operation, of stemming Soviet influence in the

Health Benefits of Yoga Essay Example | Topics and Well Written Essays - 750 words
