Cruel and Unusual Punishment: the Death Penalty

Cruel and Unusual Punishment: The Death Penalty I remember watching the movie Dead Man Walking; it was about this man named Matthew Poncelet who allegedly raped a girl and killed a teenage boy. Poncelet pleaded not guilty, but was convicted as a murderer and put on death row. He asked for several appeals stating that Carl Vitello, the man he was with at the time, was the one that should be at fault. Poncelet seems very convincing that it wasn’t him, but at the end, the courts had enough evidence to grant Poncelet the retribution of execution.The movie has me questioning America’s justice system; what if someone was actually innocent? Is it right to kill someone as a consequence for their wrong doing? To some, it seems like the right thing to do. If someone breaks the rules you simply punish them. But how should we carry out these punishments? When eight-year-old Billy steals a candy bar from Seven Eleven, you can bet that one of the parents will deliver some whippings. In Texas, when I was in elementary school, I started a fight, and as a result I got sent to the principal’s office and received three licks with a paddle.So where do we draw the line? At a higher level, what happens to me if I kill someone? Since the beginning of time, societies in almost every culture and background have used capital punishment or physical chastisement as a consequence for the killing of others. But, we shouldn’t be doing this anymore; life is too valuable. Even though some people have made mistakes in their lives, its time for the United States to free the judicial systems from their power to take peoples life’s as a consequence for people taking the life of another. In 1972, with the Furman v.Georgia case, the Supreme Court recognized that capital punishment was indeed a roll of the dice, and as a consequence held that as practiced it violated the Cruel and Unusual Punishment clause of the Constitution's Eighth Amendment. Justice Stewart decl ared that the death penalty was cruel because it is â€Å"wantonly and freakishly imposed,† and it was like â€Å"being struck by lightning† (Hull). Justice Douglas, agreed and stated that the death penalty was unusual because â€Å"it discriminates against someone by reason of his race, wealth, social position, or class† (Hull).Justice Byron White, a man who favored more executions, agreed that he noticed, that among the hundreds of federal and state criminal cases that could have resulted in the death penalty, â€Å"only a handful of defendants were actually selected for execution† — making the system â€Å"so totally irrational as to be based on luck† (Hull). The decision removed power from the states to enforce the death penalty, and moved the 629 inmates off death row.For a few years, the death penalty remained illegal because the Justices that were on the Supreme Court at the time concluded that executions violated the Eight and Fourte en Amendments, citing cruel and unusual punishment. However, with different terms, in 1976, the Supreme Court reversed itself with Gregg v. Georgia and reinstated the death penalty to state hands. Nevertheless, this is a prime example of how the Supreme Court can change laws and set precedents by the way they interpret our Amendments.The Supreme Court is in place to dissect, and analyze the Constitution to decide what the Framers meant, and in 1972, the perspicacity of the Justices resulted in the most humane decision ever made; people where being deprived from life by serving life imprisonments instead of being executed. Since 1976, the United States has executed 1,295 people, and there are currently 3,189 people on death row (DPIC). But all murderers haven’t had the same fortune, because of Gregg v. Georgia, some states enforce the death penalty and others don’t. There are currently 33 states in the U. S. ho currently support and implement capital punishment, and 17 states who oppose. (DPIC). Murderers in non-capital punishment states can kill with the highest punishment being life in prison; but if that same murderer resided in another state, he would have the opportunity, depending on the case, to be sentenced to execution, via lethal injection. The problem here lies, that there is no consistency when it come to punishing the murderers. If a murderer lives in the U. S. the reprimands should remain the same for everyone; the penalties shouldn’t differ because what climate a killer prefers living in.The laws that we have in place now, means that if I wanted to go on a killing spree, and I didn’t want to die because of it, I would simply move from a death penalty state to a free death penalty state and make my moves there. It’s not right to pick and choose something of this magnitude. Everyone in this nation should be treated equally when it comes to a life or death situation. In 2007 at the State Bar of Wisconsin Annual Con vention in Milwaukee, pro- and anti-death penalty activists gathered to debate over the death penalty. During this debate, James P. McKay Jr. an assistant state's attorney with the Cook County State's Attorney's Office in Chicago, and a pro-death penalty supporter, stated in defense that he â€Å"absolutely believes that the death penalty brings justice to a murder victim's family† (Pribek), and that he has â€Å"never called for the death penalty in a case for political purposes† (Pribek). Professor John C. McAdams, a political science professor of Marquette University in Milwaukee, and an anti-death penalty supporter, fired back with, â€Å"The state should not implement the death penalty because of its irrevocability.Whether the state is literally taking a prisoner's life, versus locking him or her up for life, the state has taken that person's life by vanquishing his or her freedom† (Pribek). Moments after, McAdams closed out the debate with the crowd on his side, stating, â€Å"If I were on the Supreme Court, I'd say that the death penalty is cruel and unusual punishment† (Pribek). Although some death penalty advocates consider themselves the voice of the innocent victims and their families, McAdams made a very notable point.Penitentiaries don’t have to eradicate the murderer to serve justice. But you can end a life; sentence the murderer to serve permanent incarceration, and you will deprive them from freedom, or in other words, life; which in return satisfies the amendments. Yet, â€Å"we the people†, continue to put the power of life or death into the hands of fallible, sometimes prejudiced, narrow-minded people and ask them to play God and determine who’s worthy to live a life that we did not bestow upon them.Sentencing someone to life is the most reasonable solution in more ways then one. There have been 140 exonerations since 1972, and from 2000 to 2007 there has been an average of 5 exonerations per year — innocent people suffering for no reason (Woodford). The average time between the sentencing to death of the once sought guilty, to their proven innocence, is 10 years. If U. S. citizens could find it in their hearts to come together and drop down to the humanitarian level, there could be change in the system with awareness, and spread of word.There has to be other people who share the same feelings, and cringe at the thought of possible government killings toward non-guilty — it’s unsupportable. Its mind boggling to note that there has been 140 non-guilty offenders put in prison with the presumption that they are going to die, and then some years later, they are freed. The probable innocent killing can easily be solved by sentencing presumable murderers to life without parole. The death penalty is much more expensive than life without parole because the Constitution requires a long and complex judicial process for capital cases.If the death penalty was re placed with life without parole, an immense amount of money would be saved. According to a California Commission report in 2008, California could save $1 billion over five years by replacing the death penalty with permanent imprisonment (Woodford). The report stated — with reforms to ensure a fair trail to the current system in place, the death penalty would cost California an estimate of $232 million a year and the cost for a system that imposed lifetime incarnation instead of the death penalty would only cost $11. 5 million a year (Woodford). Two birds with one stone.The evidence for capital punishment as an uniquely effective deterrent to murder is especially important, since deterrence is the only major pragmatic argument on the pro-death penalty side. The theory is, if murderers are sentenced to death and executed, potential murderers will think twice before killing for fear of losing their own life; what is feared most, deters most. In 1973, Isaac Ehrlich, statistician who, after looking at national homicide rates between 1930 and 1970, established an analysis which produced results showing that for every inmate who was executed, 7 lives were spared because others were deterred from committing murder.But this however, has been proven inconclusive, and results cannot be duplicated by other researchers. Then in 1997, George Pataki, the Governor of New York state at the time, stated during the anniversary of reinstating death penalty, â€Å"To fight and deter crime effectively, individuals must have every tool government can afford them, including the death penalty† (Paraki). The governor made strong relations with the death penalty and the potential of installing fear in other potential murders.Pataki continued with strong regards to the deterrence theory after mentioning that the death penalty was a key contributor to the recent dramatic drop in violent crimes — â€Å"In New York, the death penalty has turned the tables on fear and p ut it back where it belongs-in the hearts of criminals. I know, as do most New Yorkers, that by restoring the death penalty, we have saved lives† (Pataki). I do not feel that execution best punishes criminals for their acts.Instead, in my opinion, the administration of the death penalty should end because it does not deter crime, it risks the death of an innocent person, it costs millions of dollars, it inflicts unreasonable pain, and most importantly it violates moral principles. The inconsistency doesn’t make sense either, according to Nearly everyone that has been summoned to death row, is spurred from to According to our Bill of Rights, I cannot be deprived of life without due process of law (US Const. , amend. V). So if the process of law is carried out, the courts can decide to kill me if my crime is severe enough to correspond with capital punishment.But, according to the eighth amendment, I’m protected from cruel and unusual punishment ? isn’t kill ing someone cruel and unusual? Did our Framers mean that the death penalty has to be humane, or did they mean the person has to be imprisoned for life? Is it right for someone you have never met to define these so called â€Å"rights† and never be consistent with their definitions? So here we are with a lot of questions and no right answers! Yes, Poncelet did commit a crime and he should pay; but how can someone that didn’t put you in this world, take you out?The death penalty is cruel and unusual. Why can’t the court system just sentence someone to life in prison? I believe if you take the life of another, it is a form of cruel punishment. In my eyes, it could be a violation of the eighth amendment. Our fifth amendment states, that with the processes of due law, they can deprive us of life. But how can someone construe that as killing us and taking our life? The judicial courts should have interpreted this as putting someone in prison until they die. If youâ₠¬â„¢re imprisoned for the rest of your life, then you have been deprived of life.This should be enough justice. It’s not like someone will be enjoying their time. I don’t see how the people that operate the death penalties can sleep at night; killing someone because they killed just isn’t right. They should actually make a certain prison for those who have been deprived of life, the ones who have killed. The prison should have the inmates locked up in a small dark room for 24 hours a day with no contact with anyone, no bed, no blanket, just a toilet and pictures of the victims engraved into the walls of their cell.At least this way, the killer could regret what he/she did and maybe feel some sort of remorse. It would drive the person insane. It’s also messed up for the court system to appoint a state lawyer to defend you and call that a fair trail. No lawyer really cares if you win or lose the case all they care about is the money. If one is well off when it comes to money, then of course one can afford a nice experienced lawyer that would probably bust his ass and do anything to win the case, for the reason that he would probably get more money. But if you can’t afford a lawyer, they will be happy to appoint you one.He is probably making salary and his pay isn’t justified if you win or not. If your pay doesn’t fluctuate, then there is no drive; he’s not going to work as hard and not give the case as much thought. When it’s all said and done, the appointed lawyer has nothing to lose. Maybe it’s just your luck and he is a newbie and doesn’t have any business in a case involving a murder. If they want to make it a fair trail, why can’t they pay for a top notch individual lawyer who excels in that position? We should be able to pick our own, so then at least the poor person can have a chance.I mean when you’re talking about someone’s life you don’t want any Jo e Blow defending your case. Here is a statistic for you; according to American Civil Liberties Union â€Å"Approximately 90 percent of those on death row could not afford to hire a lawyer when they were tried† (Tabak). Is it okay that only some states have the death penalty? I don’t think so. If I live in Washington State and go to Alaska to kill a man, under Alaska law I will not receive capital punishment (DPIC); the worst I would get is life in prison. But if I would have stayed and did my killings in Washington, I would be put on death row (DPIC).If the United States isn’t consistent with who dies and who doesn’t, then obviously there’s something wrong. It just doesn’t seem right to pick and choose something of this magnitude. Everyone in this nation should be treated equally when it comes to a life or death situation. Here’s yet another problem that I have found: weren’t we all suppose to have unalienable rights– ri ghts that can never be taken away from us; the right to life, liberty, and pursuit of happiness? But wait; in some states they can take away our life if the crime seems bad enough.I’m no law expert, but this doesn’t seem to mesh together either. I thought the government could only suppress these rights by dictators and tyrants under oppressive regimes. The most controversial subject when talking about capital punishment is that the executioners are actually committing a crime that should put them on death row too. It’s probably the most obvious debate, but seriously, how can the same group of people who just told you that killing is illegal, turn around and kill people? That doesn’t sound fair, does it? Shouldn’t the law be equal for everyone?If murdering is illegal, then how in the hell are these people getting away with this? There’s no reason why they should get exempt from this law. They are just as bad as the criminal who committed crim e. There’s another example of how inconsistent this â€Å"act of justice† (Volpe) is being used. Two wrongs don’t make a right I don’t care how fucked up the situation may be. This law simply contradicts itself. I know I stated that it was hard to choose a side, but while writing this paper, I am confident that I oppose the whole capital punishment bullshit.Yeah, I get where people are coming from, but the reasons to not believe in the death penalty overweigh the reasons to believe in the death penalty. The only way to solve this disagreement is to actually go in and define the wording in the fifth and eighth amendments. The Framers left the Constitution open, leaving the interpretations flexible to the generations of justice to come. Once our judicial government can come to an agreement on the wording in the Constitution, then maybe we can decide if we want to continue killing people by stooping down to the criminal level.Kartha, Deepa. â€Å"10 Pros an d Cons of Capital Punishment. † Buzzle Web Portal: Intelligent Life on the Web. 5 Dec. 2009.

Finally, the â€Å"Zoo† data set Is a trivial one with 7 classes, which are animal groups, with a total of 101 instances. Each animal instance contains 18 attributes, those of which include the animal's name or race, 2 numeric for its legs and its type, and 15 Boolean-valued attributes; those that involve simple yes or no answers. The following is an analysis of 4 classification algorithms that can be optimally used for these data sets.ANN. would be a good decision when simplicity and accuracy are the overwhelming factors, like in the â€Å"Zoo† data set. This classification algorithm does not focus on the prior probabilities, and is very efficient in structure. The primary computation is the sorting procedures in order to guru out the k-nearest neighbors for the test data. There are many advantages. It is structurally trivial, but it's able to make complex decision boundaries, it doesn't need much information to be able to work, it naturally gets in tune with our probl em-solving techniques, and it learns easily.The disadvantages are that it takes quite a long time to classify and that it's somewhat hard to find the best value for k. Decision Tree The Decision Tree algorithm helps solve the problem of classifying data into multiple groups of data. It provides innovative rules for solving large amounts of classification assignments because it arks on every different type of data. It's well-suited for analyzing abundant amounts of info, such as the â€Å"Adult† data set, because it does not need to load all the data in the system's main memory all at the same time.It uses a root system to remove the burden of the problem's difficulty. The Decision Tree exploration engine is used for assignments such as classifying databases or predicting results. These decision trees should be used when your mission is to assign your records to some ample categories. They help you out with rules that are easy to comprehend, ND those which can also help you pi npoint the best fields in case of future involvement in the project. There are an equal amount of advantages and disadvantages here.In the bright side, it is easy to comprehend and to generate rules, and it makes your life a whole lot easier when the problem gets degraded in difficulty. On the other hand, once an error has been made on a node at level n, then any and all nodes at level n-l, n-2, n-3,†¦ , n-k will also be wrong. Furthermore, it is not good at handling continuous variables. Nevertheless, being able to work with mass scale database files with Just his algorithm is reputable in itself.

Ethics in Group Counseling Essay

Ethics is also termed as philosophy, which is a branch of philosophy that includes the systematizing, defending and recommending concepts of the right and wrong conducts. There are three major field of study within ethics that involves Metha-ethics that concerns with the theoretical meaning that are used to reference of moral propositions and their truth-values that can be determined, the normative ethics that concerns with the practical means of determining a moral course of action. Lastly is the applied ethics that concerns with what an individual is obligated to do in an appropriate situation or at a particular domain. This research paper can explore the various ethical issues that arise during a group session. There are certain ethical conditions that should be upheld in the panel session from the initial stages of the formation of the group to the working phase of the group. The group leader should be able to uphold definitive ethical, moral codes. Thus, the paper can enlighten the various ways that a group leader should act in the midst of a conflict as well as confidentiality within the group. In focusing on the ethical responsibility of members of a group it necessary to concentrate on the following topics that are explained as follows. Ethical Responsibility Ethical responsibility is the duty that follows the moral correct paths. The ethical responsibilities of the group entail that each member has the responsibility to be honest with other group members so that to be able to make decisions in the group sessions. It is necessary that there must be a clear moral standard from the outset. For instance, create and enforce a code of conduct that ensures that group members are treated fairly to avoid the appearance of unethical behaviors. The group leader should be able to ensure that there is transparency when dealing with group members. Also the ethical that you might feel you have, you should consider how the group‘s morality could affect the group productivity. Ethical Communication in  Small Groups Dealing with small groups work we major on focusing on getting the job done while maintain a reasonable relationship among group members. Ethics in a small group involve three levels whereby we have the individual group member, the group, and the group environment. Thus using ethics in a small group, it enhances the moral aspects of the group interaction. The ethical communication enables the human worthiness and the dignity by fostering the truthfulness, fairness, responsibility and enhancing the personal integrity. Thus, ethical communication in small groups is used for caring and accountability for oneself and other group members. Some other principles that are more applicable to small group communication involves: the truthfulness ,accuracy, honesty and provision of the integrity of communication, endorse freedom of expression and diversity of perspective together with the tolerance of dissent to be able to achieve the informed and responsible for making decision making fundament al to a civil society. Unethical communication causes threats to the quality of all communication and the consequently of the well-being of the individuals and the society. In addition, as a manager be able to create a promotion communication climate of caring and mutual understanding that exist with respect and uniqueness needs and characteristics of individual’s communicator and be able to accept responsibilities for the short and long-term consequences. Ethics is more easily discussed than putting into real practice as demonstrated by San Jose Mercury stated that the increasing trend in an organization to integrate a code of ethics for daily activities. Ethical communication requires that an effective critical thinking skills, recognizing the importance of the diverse perspectives and respect for the well-being of self and other taking the responsibility for individual and the group actions and reflecting on the choices the group members can make.. Ethics in Group Counseling During the session of group counseling, consist of the psychiatric care that many patients meet more at therapist at a time. Each group has different topics that they wish to tackle for the growth that enhances the distinction of the financial issue that an individual counseling can be able to create.  The financial tights limit the delivery of the community agency for individual counseling. Focusing on the Barlow Research stated that group-counseling sessions are more successful than the individual ones. Thus by evaluating the various facts that the states that group counseling benefit more patients at one time as well as being used more than the individual counseling. Through McCarty studies, they were able to answer questions that were concerning the indicator of the importance of group counseling as compared to individual counseling. They described the positive aspect of the group counseling as well as stipulating the negative side of the group counseling. The positive results of the group counseling involve the developing of the social skills among the group due to a safe environment in which the group members can share their thoughts feelings and ideas. In addition, the aspect that concerns the patients to be able to receive a positive feedback from their own group mate as well as various perspective on a similar issue, the group members can enhance to learn new ways in order to see a particular problem. Considering the negative aspects of the group therapy involves the clients were not speaking during a group therapy session since they are too shy to share their views in the front of other individuals. The other aspect consists of group settings and the benefits that are more important in the individual setting. The other aspect involves the issue of time which is limited and the group and the group sessions do not have flexibility date setting, thus any session that is placed by the counselor should be mandatory and set in the panel settings Characteristics of an Ethical Leader During the group, counseling session there must be proper individuals that are trained and equipped in an efficient manner to lead during the session. The individual that lead the session is considered as a leader who addresses the various issues that arise during the session. Some research that was done by Kalshoven and Hugh wanted to determine the individual characteristics that a leader requires that to lead an effective a counseling session. They stated that the major features of the ethical leader were both agreeable and conscientious. In their study, they proposed that a leader possess the traits whereby the manager requires the features to ethical standards in the counseling session. Another study that was done  by Riggio stated that the two important moral emotions that a leader must possess is the empathy for their clients as well as compassion for the individual wellbeing. Jacobs in his literature book stated strongly that leaders in group counseling must be at a state to have skills in organizing and planning the counseling sessions in order to keep orders and maintain the structure of the group. As a counselor, he/she must be able to answer the challenging question that can arise and ensure a complete knowledge understanding. The counselor should be able to understand the counseling theory to enhance proper training that can assist in the implementation of the ethical foundations. Primary Planning The counselor should be given proper training in advance with the aim of ensuring an effective ways in the counseling session. Thus, the counselor is required to attend a counseling session to have the insight to the future issues and the dilemmas they might face. Thus in the participation of that session it allows them to coin and gain the understanding and the perspective. According to Corey, the study suggested that for a minimum of 10 hours of observation and taking notes of the session. This paramount process enables the counselor to be involved in ethical decision-making and well-organized knowledge. The area of jurisdiction must be satisfactory to the counselor by screening the patients before joining the group, in a move to avoid disruption and hurting the whole group at the end of the process. During the screening session, it entailed answering, unsettled questions at the stipulated time. Further, there must be an alignment with the purpose of the group as well as make the t eam leader who will be able to meet the needs of the client as much as possible. The process of planning entails alignment of the client and counselor so that the customer will be free to the counselor to give out and share the deep and times emotions. Once the process of screening is finished, there is an informed consent section. The client that discusses what issues they will be able to encounter during the counseling sessions. The preliminary role of these step, it enables the disclosure of information to the group members to inform the clients the pros and cons of joining the group. It is also suggested that the informed consent section has potential risks that the members might face while in a group therapy session. It is well explained by the Corey survey, which  states that some clients might experience their privacy, which is a guarantee that the other member will respect their privacy The informed consent is usually presented to customers in a written and oral manner so that the clients can be completely informed of what they will encounter so that to avoid surprises when the sessions begin. In the consent, the clients are required to contain the role expectations of colleagues and the leader, the policies and the procedures that are governing the mandated group, the documentation requirements and the procedures for the consultation between group leader and the group members. Open or Closed Group It is stated that it beneficial to choose the group counseling since it is better to make a decision. There are supportive reasons to those suggestions that cause the more efficient counseling method. At first, the counselor can reach out a larger group of people. Instead of focusing much time on one person, we assist the lives of many other than concentrating on a single individual. Through group counseling, it benefits both the client and the counselor since it creates a great way to build a community and stimulate the counseling session. Secondly, the group counseling is more effective since the counselor can build his/her leadership skills this is created because of the counselors can encounter various problems and through making mistakes, they can become stronger and efficient leaders as the session progresses. The third reason it beneficial for both the counselor and the group since the counselor can be able to raise his revenue through obtaining a group counselling session as compared to one person and the member of the group can save money as well. Also, the cost of individual counseling is expensive as compared to the panel session The last reason to consider the group session is such that it is much effective since the counselor can continually learn experiment and strive to make a difference in the life of a client. Group Processes According to Corey, he stated that in-group counseling the issue of conflict within counseling in a group is common. The topic at times is inevitable within the group when you have personal clashing and perspectives within the group. However, according to Jacobs warned that the issues that are dealing with the denominator, negative member, and the overwhelming chronic talker,  and some issues of asking a member to leave are expected to arise in the counseling setting. Thus, it is important to note that some of the problems do not solely happen in the group setting but may happen as well in the personal counseling setting session. Therefore, the most important issue about conflict is not the conflict itself but how the counselor will be able to deal ethically with the issue when it arises. Thus, a great tool that one should use is to list all the conflict issues that they may arise and then gain the insight as to how to solve the issue ethically. In addition, it is desirable to seek advice from other colleagues about the tactics that may be used in the sessions to resolve the issues. The counselor is supposed to develop either an open or closed session group setting. Whereby in the public group setting session the members of the group are allowed to go and come at their own pleasure. Nevertheless, in the closed group sessions the member is required to be a continuance of the attendance throughout the designated sessions. Close relationship should be built on the counselor as well as a close relationship in-between the other group members as stated by the Forsyth who stated that the aspect of cohesion when conducting the issue of evaluation the leader must activity gain the virtue to keep the group in a cohesiveness mode. The ethical questions that arise from a closed group therapy sessions show the ability for the client to leave at any point. According to Corey, stated that a member should choose to leave the counseling session then that must openly let the group and the counselor must know that they wish to exit and the reason they exiting the group. It can be done in order not to harm the homeostatic environment of the group. Thus when the team member does not do this, it can harm the rest of the group and disrupt the growth process that there is among the group. It leads to a critical ethical topic that must be addressed in the every counseling group that is the issue of com fidelity. As a counselor it safe to uphold the confidentiality of the group members, this can lead to the group members being shy about sharing certain area their lives. There are certain aspects that the counselor can break in the confidential barriers While in the individual counseling, it involves talking personal feeling thoughts and behaviors and the things that are troubling and spend time in talking about the individual relationship with others. Your counselor will work with you to be able to set goals and the things you require to be accomplished  together. The counselor assists you to develop different strategies that can assist you to be able to reach the personal goals. In some cases, it could mean changing the pattern of thinking, learning new skills, changing the behaviors, and shifting the way you feel and express the emotions.

Information Searches - Research Paper Example Level of involvement is used to reflect how personally important somebody is in consuming product and how much you need to make the decision. The involvement of purchasing a product varies by consumer not the product. Low involvement decisions are decisions that are made by consumers on typical products that do not pose high risk to them if they purchase those products. The consumers in this level make automatic purchase decision based on limited information they have gathered on the product. Middle involvement purchase is the in which consumers don’t rush in making purchase decisions but rather they gather information that enables them think and make appropriate decisions regarding the product. They choose the product of middle classes and not ones that are expensive in nature. High involvement purchases are that which carries a higher risk to consumer if they fail to buy the complex, with higher price tags of goods. Buyers don’t engage in in routine response when purc hasing high involvement products. The purchasing power of consumer in this level of purchase is determined by the price of the product to be purchased. Consumers in this level of purchase only consider purchasing goods of high prices or luxurious goods. Discussion Marketing action planning helps producers to market their product and services effectively. The best way to plan for your market action is by one researching about their customers so that they can understand how best their products and services can hit the market target. The scheduling system one uses doesn’t matter as long as it is consistent and it can work better for your purchasing plan. For one to actual be successful in purchasing strategy he/she should consider the following three marketing actions: The on-going marketing ;action The one-time marketing actions The idea generation actions The on-going marketing action The on-going marketing activities are that which deals with normal day-day business actions. Examples are; Advertising, direct mail activities, writing blog posts, networking on a social network such as twitter. The main purpose of marketing actions and strategies is to result in making the required product available and can satisfy customers need and interest while making profit for those companies. The daily actions taken by the business does not give customers to find enough time to research about the products they want to acquire, but through the channel of advertisement and mailing they can have some recommended knowledge about the product he wants to consume. The one-time marketing action This is an action that is done by business on need basis. They are always carried out once in a while especially when there is a development of a new product or an introduction of a new product in the market. Example of such actions is; developing a workshop, creating a new product or service, setting up an affiliated program. This kind of action gives the customer/consumer a rough i dea but one that can be relied upon when buying the upcoming product. This action is always more appropriate to the medium level involvement purchasers who require some rough ideas about the product to be consumed. Idea generation action Is organising and scheduling some safe time for cropping new ideas that is relevant to your market and the influence of consumable products. This provides you with additional opportunities to increase your income. The action is always considered by big investors such as the real estate

Advertisement Analysis Essay Example | Topics and Well Written Essays - 1250 words

Advertisement Analysis - Essay Example In short, consumer culture has largely influenced the way of living today. In the light of these, the following study text seeks to support the impact of consumer culture on society by analysing an advertisement based on the relationships between the aesthetic strategy and ideological message applied in creating it. In analysing an advert, two major aspects come into play; the aesthetic and ideological portrayals. The aesthetic aspect represents the overall visual sensation which is portrayed by the advertisement’s overall appearance. In short, it is the visual appeal, and plays an overly important role in marketing. The ideological message represents an advanced meaning of the advert and is a simulated â€Å"feeling† which is transferred from the advert to the consumer upon buying (possession) of the product being marketed. These two are closely related. In an advertisement, there are three main constituting understandings; the overall (surface) meaning, the advertiser’s intended meaning, and the ideological (cultural) meaning. The relationship between the three is that the aesthetic sensation adds up to the surface meaning while the ideological message represents the advertiser’s intention. These two combined, they create the cultural meaning of the advert thus its interpretation and execution of the intended purpose (Botterill, MacRury & Richards 2013, p. 81). Figure 1 above is a Vive Cuervo Advertisement. Vive Cuervo is an alcoholic drink. The aesthetic strategy is evidenced by the inclusion of different elements which create a composition. The composition is made up of both images and text. There is the image of a happy couple in beachwear wherein man is carrying his lady at chest level. They are in embrace as he holds her around her buttock area and her legs embrace his abdomen. The lady’s hands are clutching the man’s neck tightly and they are both laughing out loud.

Experiencing Long-term Care, Rehabilitation & Recovery (BSc Adult Essay

Experiencing Long-term Care, Rehabilitation & Recovery (BSc Adult Nursing) - Essay Example The study focuses on two themes that are important to understand long term conditions and long term care. These themes are; self care/self support and supported care management. Self care/ self support involves persons with long term conditions managing their own care plans without much help from others for instance nurses and other professionals. This concept is known as â€Å"expert patient† and it is based on the premise that the person with the condition or disease understands it better than health care professionals. These patients have more knowledge about their conditions and have therefore learned ways of managing them. The patients undertake programs which provide information, resources and ways of developing relationships with healthcare bodies. This approach has demonstrated benefits for patients because they possess more knowledge of their conditions, ensures participation in decision making and get involved in the symptoms management processes. Although the concept of â€Å"expert patient† has its advantages, we must always be mindful of leaving some patients feeling abandoned and neglected when they are not able to manage skills and information they have been provided with. It is therefore advisable for patients to enroll in the supported care where nurses and other professionals are able to take care of both their personal and health needs. This is the reason that there must be a partnership with the patients, nurses and other professionals. The second half of the twentieth century brought a realization that due to the increase in numbers of people living with long term conditions (LTC), health care needed to be improved with an emphasis on patients being empowered to become decision makers in their care (Margerson, 2010). In the case scenario of Angela, the study concludes that she should focus more on supported care management where professionals with vast knowledge will assist

Someone who inspired you and what the inspiraton was Essay

Someone who inspired you and what the inspiraton was - Essay Example However, the main reason I admire him so much is because I know from what my parents and him told me how extraordinary his life has been. Unlike my parents, he never finished college and had to do many menial jobs – something he probably regretted later a lot. I came to learn that his youth was a wild one, and he dropped out of college halfway due to drug related problems. At that time, he had sunk so low that he would disappear for months living in shelters for homeless people, and the sense of his life was the next dose. Even his own family had given up hope on him; however, his struggle is something I can only describe as the greatest act of self-redemption I have ever heard of: he turned his life around, and today he teaches literature at a local college and has a PhD degree in the same subject. After he got rid of his drug problems, he worked nightshifts at a factory, and during the day did distance courses. No one thought he could keep this up, but to everyone’s s urprise, he finished college in three years. Having got his diploma, he worked as a teacher at a local high school teaching English to foreign students on a part-time basis to earn some extra money. By spreading himself thin in ways I will never come to comprehend, he managed to acquire a master’s degree finishing his education in a span of only five years. These days my uncle gives motivational talks to youths and homeless people as well as people with drug problems. Also, he finds time to talk once a week in a drug rehabilitation center that was founded by him and a few other sponsors. His taking care of people in need, shows what an altruistic and understanding person he is; my uncle believes, like one of his role models Martin Luther King, that love has a redeeming power and can change the world. His massage to them and everyone else is that everyone deserves a second chance, and one should always take time to help those have lost hope and support. To me,

Philosophy Essay Example | Topics and Well Written Essays - 1250 words - 1

Philosophy - Essay Example Basing our argument on philosophy, it can be noted that the previous philosophy or rather the ancient philosophy do not give out the same picture as it used to be some years ago. As the way of life changes, so are things like philosophy and sociology just to mention but a few. However, before a change can fully be implemented, there must be a motivation. The same applies to the modern philosophy. Before attaining its current state, there was a motivational appeal, which our ancestors anchored on to foster the attainment of their desires. First, our ancestors had a sense of recognition in that they recognized the existence of a new path that had departed from the medieval scholasticism. From that point, they started to refer to their own philosophizing style as â€Å"modern.† Notably, the recognition of medieval scholasticism departed path designating the modern philosophy. Secondly, the early philosophers acknowledged the Greek philosophical schools, after which they breathed life back to them. The philosophers believed that the schools contained the middle age’s lost vitality, which they knew would help them drive to the modern philosophy. In short, education was a pertinent motivator to the modern philosophy. In other words, education laid a foundation to proper thinking, and so it motivated the philosophy to their destiny. Thirdly, freedom formed another motivator to the current philosophy. Through freedom, the early philosophers got the chance and time to move freely out of the oppression of the Catholic Church. In doing so, they stood on a good position of defending themselves from the trouble they experienced with the religious and legal authorities. It is noteworthy that most innovative philosophers always experienced impeachment as heresy. However, freedom made them overcome these accusations. Lastly, scientific achievements in fields s uch as biology, engineering, chemistry, and astronomy staged the early philosophers on a good platform of

Team Leader Interview Research Paper Example | Topics and Well Written Essays - 2000 words

Team Leader Interview - Research Paper Example The size of a team differs in every organization. This is due to the fact that different organizations and departments have dissimilar objectives, different goals and different expectations in terms of success and the final product. For every organization, to determine how many members will make up the team, different variables and factors are considered (Drouin, 2013). One major factor that is considered is the expectations that the leaders and management have on the team. Different expectations determine how big or small a group is. When the expectations are too high, an organization might decide that the best way to achieve them is by forming a large team (Avery, Walker and Murphy, 2001). In addition, it is important to consider the roles that each of the team members is going to play. If each individual in the team will handle different aspects in the task, the team size might be different as compared to when all team members will handle similar aspects in the task as noted by Mountain and Davidson (2011). Another factor that is considered is the amount and extent of cohesiveness and the level of interconnectivity that is found in a team. Cohesion and interconnectivity are pertinent towards ensuring successful teamwork. When the connection and cohesion is high, the number of members in the team can be less and when it is low, the number should be increased (Edger, 2012). It has been hard to determine the optimum team size, but researchers propose that effective memberships are made of between 4 to 11 members (Robbins and Judge, 2013). However, recommendations brought forward by researchers suggest that 7 to 12 members is an optimum number for problems necessitating high quality decisions (Drouin, 2013). Secondly, when it is important to reach a consensus on a conflict, 3 to 5 members is essential and lastly, when quality and consensus is deemed most

Neocolonialism Essay Example | Topics and Well Written Essays - 1000 words

Neocolonialism - Essay Example As a result, some guidance needs to be provided to the weaker nations in order for them to ultimately gain economic independence as well as political independence. One of the theories involving neocolonialsim is called the Dependency Theory. This theory discusses the relationship between less economically developed countries (LEDC's) and more economically developed countries (MEDC's). The theory maintains that the LEDC's are in the underdeveloped situation that they are in because they rely too heavily on the MEDC's. The LEDC's will remain LEDC's because any surplus production will be absorbed by the MEDC's multinational corporations leaving no profit for the LEDC's. Yet, the MEDC's are also dependent (Dependency Theory, 2003). Without the LEDC's, they would not be able to prosper to the level that they do economically. This neocolonialism is the source of multiple frustrations for several smaller nations. One example of this opposition comes from the Pacific Islands Association of Non-Government Organizations (PIANGO). They cite the United Nations Declaration of the Rights of Indigenous Peoples which declares that indigenous peoples (who are usually members of these LEDCs) have the "right to self-determination and political independence (Blaisdell, 1998). ... They are the continued victims of US economic dependence and exploitation which keeps these countries at Third World status (Blaisdell, 1998) Similar tensions surround Jamaica, Brazil and Southeast China, to name a few. Although the MEDC's pat themselves on the back for bringing industry and paying jobs to poverty-stricken areas, the damage to the country and to the people themselves has been compared to the physical cruelties of Cortez as he ravaged Mexico for gold in the 16th century. The difference is that this type of attack is not condemned like physical, military invasions by world nations and leaders. In fact, it is often allowed by the LEDC's government, ignored by journalists and kept from the broader public. (Ayres, 2004). Indeed, the companies do hire uneducated indigenous people to work these sometimes dangerous jobs; they cannot quit because they are dependent on the income. Some companies have even been accused of paying bribes to some village leaders to publicly support the industry in spite of possible problems with the health or environment as a result (Koenig, 2004). Koenig, in World Watch, details an example in Romania. Heap-leach gold mining is a modern form of mining which makes use of literally millions of gallons of cyanide poured onto piles of ore. The cyanide helps to extract the gold. In Romania, at an Australian-owned min, a dam broke and polluted the Tisza River with 22 million gallons of the toxic substance. It has been six years since what environmentalists are calling the worst catastrophe since Chernobyl, but this mining process is still on the rise (Koenig, 2004). Of course, many international researchers place the

Simple Harmonic Motion (SHM) of a Simple Pendulum Essay Example for Free

Simple Harmonic Motion (SHM) of a Simple Pendulum Essay Objectives: To study the simple harmonic motion (SHM) of a simple pendulum and to investigate the phase relationship between the displacement, velocity and acceleration, and to investigate how acceleration is related to displacement in a simple harmonic motion. Apparatus: * half metre rule * a light string * pendulum bob * video camera with tripod stand * computer with Motion Video Analysis (MVA) software and Microsoft Excel installed Experimental design: Fig. 0 Theory: For an object or mass moving in a simple harmonic motion, the displacement, velocity and acceleration change periodically in both magnitude and direction. The acceleration in particular is always proportional to its displacement from the equilibrium position and must always be directed towards the equilibrium point. Mathematically it can be expressed as a = -kx, where k is a constant and x is the displacement from the equilibrium point. Also for a simple harmonic oscillation, the period or frequency of oscillation is independent of the amplitude of the motion. In Figure 1, x is the displacement of the pendulum bob from the equilibrium point Q. Points P and R are points where the maximum displacement (amplitude A) can be obtained. Theoretically, the following equations are true for S.H.M.: When the motion starts at the equilibrium position (point Q) x = A sin ?t where ? is angular velocity v = ? A cos ?t a = ?2A sin ?t Period T = 2 ? / ? Fig. 1 When the motion starts at the position where the amplitude is obtained (point P or R) x = A cos ?t where ? is angular velocity v = ? A sin ?t a = ?2A cos ?t Period T = 2 ? / ? In theory, the displacement-time, velocity-time and acceleration-time graphs should be in a sine or cosine curve. Moreover, the velocity graph should lead the displacement by a quarter of the cycle (? = 90à ¯Ã‚ ¿Ã‚ ½), and the acceleration graph should lead the velocity by also a quarter of the cycle. This can be illustrated by the fig. 2(a), (b) and (c). Fig. 2(a): Graph of displacement x against time (Suppose the motion starts at the point where lower amplitude is obtained) Fig. 2(b): Graph of velocity v against time Fig.2(c): Graph of acceleration a against time Procedure: 1. The set-up was assembled in the following procedures: (a) One end of the spring is clamped firmly on the stand. (b) The ringed mass was attached to the other end of the spring. (c) A half-metre rule was clamped on the stand beside the spring and mass such that the top of the half-metre rule corresponds to the top of the spring. (Refer to Fig. 0) (d) The equilibrium position was marked by a sticker. 2. Take readings by using the apparatus in the following procedures: (a) Student holding the white foam board (Student A) (i) Hold the white foam board behind the set up so that the movement of the spring system is not disturbed by any other backgrounds. (b) Student conducting the experiment (Student B) (i) Stand beside the set up. Make sure that the spring system at equilibrium is in a steady and stable condition. (ii) When the video taking was on, pull down the spring some distance (e.g. about 5 cm) and set the spring moving. (iii) Make sure the spring is mostly moving in a vertical direction and not swinging to and fro. (iv) After a few oscillations, ask student C to stop the video. (c) Student conducting the video-taking (Student C) (i) Set up the video camera and fix it on the tripod stand firmly. (ii) Adjust the position of the camera so that the spring system and the movement of the spring is shown clearly. (iii) Watch out for Student B to start or stop the video-taking. 3. Convert the video into suitable format. 4. Use the MVA software to record the positions and times for 2 complete oscillations of the mass. Save the project and export the data to a text file. 5. Use Microsoft Excel to open the exported files and plot the graphs for displacement, velocity and acceleration against time respectively. Also plot a graph of acceleration against time. Results and Measurements: (Copied from the data of MVA software) Values of velocity is found by the equation: (x2-x1)/(t2/t1), whereas x1=-7.54E-02 x2= -4.08E-02, t1=0.00E+00 ,t2=6.67E-02 Values of acceleration is found by the equation: (v2-v1)/(t2-t1) Whereas v1= -1.30E-02,v2= 5.20E-01, t1=0.00E+00 ,t2=6.67E-02 E+00= 100=1; E-01=10-1; E-02=10-2 E-03=10-3 (See the bolded ones as reference)

-9.78E-02 1.22E-02 3.67E-01 -3.67E+00 Experimental results in graphical representation: Analysis: (a) Shape of displacement-time, velocity-time and acceleration-time graphs From the experimental results and the graphs plotted above, it appears clearly that the displacement-time, velocity-time are in the form of sine and cosine curves respectively. For acceleration-time, due to errors in marking, may not appear as clear as sine curves. It can be seen more clearly after drawing a trend line. (b) Value of amplitude A and ? it can be read from the graph of x against time that the amplitude is within the range of 0.15-0.25m. Also, read from the graph, ?à ¯Ã‚ ¿Ã‚ ½3.0s (c) The phase relationship between the displacement, velocity and acceleration By comparing the graphs of displacement-time, velocity-time and acceleration-time, it can be seen that the velocity leads the displacement by a quarter of the cycle, and the acceleration leads the velocity also by a quarter of the cycle. (d) The relationship between acceleration and displacement in a simple harmonic motion From the graph of acceleration against displacement x, the points tend to form a straight line going through the origin with a negative slope. It can be deduced that acceleration is directly proportional to displacement in a simple harmonic motion and is in an opposite direction to x. Error and Accuracy: Errors Systematic Error Random Error The motion of the spring system is not entirely vertical. The half-metre rule is not clamped vertically. The origin is not marked very accurately in the MVA software. The two ends of the half-metre rule are not marked accurately in the MVA software. The position of mass marked for each time interval may not be the same for all time intervals. There may be a damping effect by air resistance. The spring may not be perfectly elastic (1) The motion of the spring system is not entirely vertical No matter how carefully we set the motion off, the spring may not be moving vertically all throughout the motion. It may swing to and fro instead, hence the motion may not be entirely a simple harmonic motion, causing deviations in displacement obtained. (2) The half-metre rule is not clamped vertically The half-metre rule is not entirely vertical, so the marked points on the MVA software do not indicate an actual distance of 0.5 m. As the MVA software requires the setting of the end points of the half-metre rule as a reference to locate the displacement, the displacement at each time interval does not reflect the true value of the displacement. (3) The origin is not marked very accurately in the MVA software The inaccuracy of the centre of mass marked in the MVA software will result in the shifting up or down of the graphs of displacement, velocity and acceleration against time. (4) The two ends of the half-metre rule are not marked accurately in the MVA software As the two ends of the half-metre rule may not be marked accurately in the MVA software, the distance marked may not be exactly 0.5 m. Same as error (2), as the MVA software requires the setting of the end points of the half-metre rule as a reference to locate the displacement, the displacement at each time interval does not reflect the true value of the displacement. (5) The position of mass marked for each time interval may not be the same for all time intervals It is difficult to locate the mass at the same position for each time interval, therefore the displacement obtained is not accurate for each time interval. (6) There may be a damping effect by air resistance Air resistance exists, hence a damping force acts on the mass in motion, resulting in smaller and smaller amplitude obtained and also causing deviations in displacement. (7) The spring may not be perfectly elastic As the spring provided may not be perfect, the whole motion may not be entirely a simple harmonic motion. The graphs obtained from the experimental results may not truly reflect the characteristics of a simple harmonic motion. Conclusion The velocity leads the displacement by a quarter of the cycle, and the acceleration leads the velocity also by a quarter of the cycle. Also, the acceleration is directly proportional to displacement in a simple harmonic motion and is in an opposite direction to x. Possible improvements of the experiment 1. A heavier mass could be used to obtain a smoother motion. 2. If possible, more trials can be done to average out the random errors and obtain a better result.

Relationship Between Management Theory and Practice

Relationship Between Management Theory and Practice In this answer the relationship in between management theory practice is clearly defined, starting with defining the meaning of management theory, later on the relation in between the two is highlighted followed by a critical review conclusion. WHAT IS MANAGEMENT THEORY? Management theory is a lens that allows people to interpret modes of management, to identify a particular set of problems and to seek a variety of solutions to those problems. Management practices in different organisations depend on the theories that are applied either explicitly or implicitly (Soriano, 2009). RELATION IN BETWEEN MANAGEMENT THEORY PRACTICE Every living practioner is prisoner to the ideas of a dead theorist(Mullins, 2007, p.40). Management theory is a critical element that helps in the production of knowledge, bringing transparency, accountability and accessibility to the research practice (Brownlie, 2007). Theories are perspectives with which people try make sense of their experiences. The relation between theory practice is very important as without theoretical knowledge it is impossible to put the skills into practice and make the right decisions. Theory gives deep understanding and allows manager to view the problems from different perspectives which leads to decision-making practice. In relation to the problems faced by organisations today, without understanding the basics of it, without knowing the case in depth, it becomes difficult to come to the right decision and solve the problem which causes the delays in decisions results(Stoner et. al. 1995, pp. 31-2). Thus, Six Sigma a system ofÂÂ  practices ev olving from best management theories was developed by Motorola in the 1980s to improve processes by eliminating defects (Pande, 2007). It is therefore very important for people leading the organisations to have a good theoretical knowledge. CRITICAL REVIEW As per a report in The Sunday Times (2009), in the last two decades, management theory, once rejected in Britain by both unions and management, has been deliberately implied on almost every aspect of commercial and public life (Billen, 2009). This act of blindly implying theories into practice is incorrect moreover certain beneficial management practices are the ones not mentioned in management theories. As stated by Gary Hamel in The Future of Management, several leading executives-including Sergey Brin and Larry Page (the Google Guys) and John Mackey of Whole Foods Market, never went to business school had no knowledge of management theories, still their management practices were successful (The Econmist, 2007). In most of the organisations there appears a gap between theory and practice of management, this problem is attributed to converting research knowledge into practice to solve this researchers propose a method of engaged scholarship in which researchers and practitioners coproduce knowledge that can advance theory and practice in a given domain (Ven et. al, 2006). CONCLUSION In managing, as in any other field, unless practitioners try to learn by trial and error method, there is no place they can turn for meaningful guidance other than the knowledge underlying their practice; this knowledge is theory. Managers who attempt to manage without management theory must put their trust to luck, intuition, or their experience in the past. A management who makes serious attempts to translate management theory into practice is bound to increase productivity more than a management which chooses to use the fire brigade or trial and error approach (Weirich, 2004). Q:Explain the main difficulties in studying personalities; how is this of importance to organisations? A: INTRODUCTION: In this answer, the difficulties in studying personalities are highlighted, by defining the meaning of personalities mentioning the reasons for the difficulties. Later on, the importance of understanding personalities to organisations is mentioned followed by a conclusion. MEANING OF PERSONALITY: As per Websters Dictionary Personality is derived from the latin word persona, which means mask as in mask worn by actors on stage or role as in ones role in life, so personality is essential character of a person (David Knights and Hugh Willmott, 2007, p.80). Difficulties in Studying Personalities:Â   No two individuals have exactly the same personalities, as stated in The New York Times (2009) It is said that parents of one child believe that upbringing determines personality, but parents with two children believe in genetic tendencies. The evidence points to something more complex: genetic predispositions interact with circumstances to produce unique individuals (Aamodt Wang, 2009). So, studying personalities is a complex task as the techniques that are used to collect group data is questionable and the outcome that comes from it is inappropriate in understanding personalities because the richness and depth of an individuals personality cannot be revealed in superficial pen and papers questionnaires. The personality cannot be understood outside an individuals social context and has to be studied in the light of his/her own perceptions of the world. Moreover, the categories defined by psychologists to study personalities are quite narrow in depth and scope. We expect individuals behaviour to be consistent or stable, however it might not be true everytime, for e.g if a person has taken drugs or is under great stress he will not behave as per his personality traits (Mullins, 2004). Importance To Organisations: Those who manage or even aspire to manage organisations a vital part of their role is understanding human behaviour and psychology (Rollinson, 2005).Within the mainstream thinking and practice of management personality is seen as one of the most basic and fundamental features of an organisation (David Knights and hugh willmott, 2007, p.79). The study the personalities can help organisations in solving real problems that happen at the place of work. By using personality psychological research findings the organisations can hire better employees, decrease absenteeism, increase job satisfaction solve many other organisational problems related to work. Understanding of personality is required in various organizational processes for e.g. Selection Placement. As per Africa News (2005) personality is the key element organisations need to assess when recruiting people. Apart from such processes understanding personalities can help organisations in redesigning jobs to make them more meaning ful and satisfying to the employees which in turn will lead to healthy and productive workforce. An organisation should recognise and try to improve employees personality and talent so that certain positive and encouraging traits can be developed in them which would lead to better work atmosphere and attainment of common aims and goals (Paul M. Muchinsky, 2001). CONCLUSION It can thus be concluded that personality is a major factor that determines the success or failure of the individual but understanding personality is a complex process, so the organisations should be careful in selecting its employees by understanding their personalities should also try bring positive changes to their personalities for organisational success. Q: In what ways can an understanding of motivation theory contribute to successful organizational working? Illustrate your key arguments with organizationally based examples. A : INTRODUCTION In this answer, the importance of understanding motivation theories for organisations is mentioned, with the help of surveys, organizationally based examples press releases. In the beginning the different motivation theories are described in brief, followed by explanation of reasons for understanding them. WHAT IS MOTIVATION WHAT ARE THE DIFFERENT MOTIVATION THEORIES? The term motivation derived from the Latin word movere, meaning to move (Kretiner, 1998). As per Robbins (1993) motivation is the willingness to put high levels of effort toward organizational goals, conditioned being the efforts should satisfy some individual need (Ramlall, 2004). The first theory of motivation was developed by FW Taylors was called Scientific Management Theory. Taylor believed money was the only motivator and that there should be a carrot and stick approach to motivate people. Those who worked hard should be rewarded, but those who didnt, penalties should be imposed. Other theorists proposed that this was not always the way to get the best out of people (The Times 100, 2010,Motivation how Egg unleashes the power of people). So there other motivation theories got evolved namely Content theories attempt to explain those specific things that actually motivate the individual at work Process theories that attempt to identify the relationship among the variables that make up motivation (Mullins, 2007). CONTENT THEORIES 1) Needs theories: Maslows hierarchy of needs theory identifies five major basic needs: a) physiological b) safety c) love/affiliation d) esteem e) self-actualization. This theory provided organisations ways of motivating employees by devising programs aimed at satisfying unmet needs (Ramlall, 2004). Champagne McAfee (1989), cited ways for organisations to meet the needs of their employees:-Physiological: Vending machines, Drinking fountains; Safety: retirement benefits, solving grievances, Rest periods; Affiliation: creating team spirit, using periodic praise; Esteem: Encouraging participation, giving training; Self-actualization: Encouraging creativity, providing challenges. LIMITATION: The level and type of employees need may vary, fulfilling some needs might be really costly(Ramlall,2004). 2) Herzbergs two-factor theory: As per Herzberg (1968) financial rewards do not always satisfy employees, as proposed by Taylor. This theory assumes that the absence of hygiene factors like salary, security, working conditions leads to demotivation amongst the employees whereas motivators like achievement, recognition, responsibility, nature of work leads to motivation (Quader Quader, 2008). This theory teaches organisation that for an employee to be motivated, his job must be fully enriched where he has the opportunity for achievement and recognition (Ramlall, 2004). LIMITATION: This theory can only be applied to manual workers the theory is methodologically bound (Mullins, 2007). 3) McClellands Achievement motivation theory: McClellands work originated from the relationship between hunger needs and the extent to which imagery of food dominated thought processes. McClelland saw the achievement need as the most critical need for the countrys economic growth and success. LIMITATION: The theory is generalised however, different people have different achievement needs (Mullins, 2007). PROCESS THEORIES: 1) Equity theory: Equity theory states that individuals are concerned not only with the absolute amount of rewards they receive for their efforts, but also with the relationship of this amount to what others receive. If they find any imbalance, tension is created people can do many things to remove this inequity. Therefore organizations must develop reward systems that are fair and equitable for all the employees (Ramlall, 2004). LIMITATION: It fails to specify what will people do to reduce the inequity/tension (Muchinsky, 2003). 2) Attribution theory: This theory suggests that behaviour is determined by a combination of perceived internal forces (skills, ability) and external forces(policies, weather) (Mullins, 2007). LIMITATION: If an employee performs well but the manager thinks this was due to luck, the appropriate recognition/reward may not be given employee will get demotivated. 3) Expectancy theory: As per this theory people are motivated to behave in ways that produce desired combinations of expected outcomes (Kreitner Kinicki, 1999, p.227). This theory states that the task itself is key to employee motivation so organisations should follow job enrichment and job rotation to increase motivation. LIMITATION: Expectancy models are not always easy to understand, or apply in actual management (Mullins, 2007). 4) Goal-setting theory : It says individuals are motivated by specific difficult goals their behaviour revolves around the set goal (Gordon, 1996, p145). It helps organisations in gaining improved results as employees set specific goals directly related to their work (Mullins, 2007). LIMITATION : If goals are set at a very high level to achieve, performance suffers, especially over a longer period(Mullins,2007). LITERATURE REVIEW: In the past theories of motivation a lot of importance was given to recognition factor of motivation the only dependent variables were job satisfaction performance. Later on, Significant advances were made in understanding how culture, characteristics of the job, and the person-organization fit influenced motivation. Earlier, motivation was restricted to research findings of North Americans. There were clashes amongst theorists that existed throughout much of the twentieth century hence much of the energy was spent on destruction of theory rather than theory construction (Latham Pinder, 2005). WHY IS IT IMPORTANT TO UNDERSTAND THEORIES MOTIVATE EMPLOYEES? Organisational investments in employee motivation create obligations on the employees to reciprocate in positive ways, which, in turn, result in better organisational performance (Lee Bruvold, 2003). Moreover, motivation theory can go a long way towards helping us understand why people behave in the way they do. Armed with such knowledge, managers should be better placed to direct employee behaviour for the good of the organisation (Hannagan, 2005, pp. 350-351). As stated by Amer Zureikat, regional Manager, Bayt.com. in United Arab Emirates (2009), Organisations the world over are realising that successfully motivating staff on an ongoing basis is a fundamental element in building good rapport among staff, keeping staff loyal to the company and most of all maintaining optimal productivity levels of employees. This becomes even more crucial during these times of economic crisis, because news of job losses and an unstable future may serve to de-motivate employees significantly. MOTIVATION REDUCES ABSENTEEISM It is mentioned in The Irish Times that up to 50 to 80 per cent of an organisations total expenditure is on employees, even average absence levels can represent a serious expense in terms of reduced productivity and can reduce employee retention because of over-stretched staff. An initiative to lower absenteeism makes financial sense to the organisation. This can be done only if the motivation theories are understood put into practice (Madden, 2008). MOTIVATION IMPROVES PRODUCTIVITY PERFORMANCE: Georgopoulos et al.(1957) Porter Lawler (1967) found that employees for whom money was a motivator, performed better if more money was offered to them (Edwin A. Locke, 1970). West and Patterson suggest Where the level of satisfaction is generally high employees may be more motivated to engage in pro-social behaviours and make extra effort to help other departments and functions. Over thousands of instances of helping and motivating the employees show that it increases productivity and performance (Robin Fincham Peter Rhodes, 2005, p.232). MOTIVATION IMPROVES TEAMWORK CO-ORDINATION Certain gain-sharing programs, such as the Scanlon Plan, Improshare, or Rucker Plan, helps workers to get a share in productivity improvements. Such programs result in increased coordination, teamwork and knowledge sharing. They also contribute to better attainment of social needs, increased acceptance of change of technology and new methods. It causes more efficient management and planning, reduction of overtime for workers, increase in creativity and implementation of new ideas and more flexible labour and management relationship (Judith R Gordon, 1996). CASE STUDY BLACK DECKER: A new program Everyone Counts based on employees social self esteem needs as per the needs motivation theories was implemented at Black and Deckers Household Products division in Shelton. Everyone Counts, an employee incentive campaign, replaced the suggestion box and allowed teams of employees to provide cost saving, cost analysis and implementation suggestions. Thirty-nine teams were allowed to submit five ideas each in twelve weeks. One such idea is estimated to save the company over seven hundred dollars by substituting a new material in one of the product lines. Everyone counts also improved communications with upper management, increased employee involvement and allowed more centralisation of the employee work environment (Harris Kliener,1993). Examples to show the Link of Motivation with Organisational Success: American Express introduced an incentive plan for 10,000 employees in the consumer-lending and consumer card groups after a one year pilot program, during which 98 percent of 1,500 employees received bonuses of 4 percent of their salaries. The plan resulted in an increase in customer satisfaction, employee productivity and shareholder gains (Judith R.Gordon, 1996). Royal Bank of Scotland: RBS provides world-class employment package for every employee adopts an attitude that motivates its staff in both financial and personal ways. This helps RBS to compete for the best people and attract them to its business has lead to RBS being rated as one of the best employers in the world. Thus following motivation theories has proved beneficicial for RBS (The Times 100, motivating through total reward). CASE STUDY OF HONEYWELL: Honeywells Electro Optics Division was in serious financial trouble because of low employee morale. In order to motivate their employees they turned to the Boston office of Bernard Hodes for a motivational programme. Posters of the five great performers with their chosen quote were made and placed in the hallways. The five great performers were instant celebrities and everyone wanted to be one. It enhanced employees performance by the use of motivation. In six months Honeywell was out of the financial trouble (Harris Kliener, 1993). There are several examples to show importance of motivation, Some of the better known examples include the Digital Equipment Corporation plants at Enfield in America (Perry, 1984) and Ayr in Scotland (Buchanan McCalman, 1989). In Britain, empowered self-managing teams can also be found in The Body Shop, Unipart, Frizzell Financial Services, Ciba UK and in the Harvester Restaurant in Dulwich (Pickard, 1993).Many American companies have adopted motivating and team working methods, like Shenandoah Life Insurance, Harley-Davidson, Compaq, Cummins Engine Company, Procter Gamble, and General Motors (Hoerr et al., 1986; Hoerr, 1989; Peters, 1987) In most of these companies role of traditional first line supervisor was changed and in others they have been replaced by people who were more motivating (David Buchanan Andrzej Huczynski, 1997, p.96). CONCLUSION: Thus, with the different examples shown it can be concluded that by understanding the importance of motivation organisations can prosper, it can also be said that apart from money there are other motivators of great importance as well, like job security, challenging tasks and working together with colleagues in a good working environment. It has been seen that great organisations are the ones in which the employees are motivated to bring out the best in them. It is therefore very important for the organisations to understand that the employees are an organisations most precious asset anything that can be done to increase their capability should be done so that the returns come to the organisation.

2D Colloidal Nanocrystal for Optoelectronic and Solar Cell

2D Colloidal Nanocrystal for Optoelectronic and Solar Cell Novel 2D colloidal nanocrystal for optoelectronic and solar cell applications Recently, 2D material has attracted tremendous attention due to their fascinating physicochemical properties. Particularly, the discovery of graphene, a single layer of carbon atoms arranged in a 2D honeycomb lattice has ignited the research on this class of 2D materials due to extraordinary mechanical, electric and optical properties not observed in their bulk counterparts. Considering graphene is a simple material composed of only carbon element, it cannot satisfy the increasing requirements of diverse applications due to limitations in the versatility and the tunability of composition, structure and functionality in addition to the paradox between the high-mobility Fermi−Dirac electronic structure and the need for a size-dependent band gap for traditional semiconductor devices. As a result, of paramount importance and interest is to search alternative 2D materials which possess much more flexibility and diversity of composition, structure, and functionality. Layered metal di chalcogenides such as WS2 and MoS2 have been extensively investigated. Like graphite, the atoms within the host layers form strong covalent bonding with relatively weaker interactions between layers such as van der Waals force. Consequently, micromechanical cleavage by Scotch-tape is the most straightforward method to obtain an individual layer while retaining their intrinsic host structure. Though it is crucial to evaluate their physical properties, this approach is time-consuming and the yield is also low. More recently, a direct liquid exfoliation where a suitable solvent is selected to stabilize cleaved crystallites was proposed to produce nanosheets. This process, comprised of ion-exchange, osmotic swelling, and exfoliation, is useful, but the concentration of unilamellar nanosheet in the solution is still very low with the yield no more than a few tens of percentage and the properties of the resulting nanosheets are dictated by their parent 3D materials, which loses the opport unities to design and control over chemical composition and structure. In order to meet the demand for fabrication of functional nanostructured electronic and optoelectronic devices, a facile process to produce large amount of 2D nanocrystal (NC) with possibility of tuning the properties is really imperative. Colloidal chemical synthetic route has been demonstrated highly attractive and powerful for their low-cost synthesis to obtain NCs from solution in excellent yield with a good uniformity in terms of chemical composition, surface properties, shape, and size. The complete control over size, shape and structure of the colloidal NCs via tuning reaction chemistry provides new pathways to design material where size or shape dependent properties can be exploited. In this project, the metal dichalcogenides such as MoS2 and WS2, typically with a trilayer structure of covalently interconnected layers of S, M, and S atoms, will be the main candidates. High performance solar cells built from them in 2D NC form is the final goal. As such, colloidal synthetic route will require balance of the reagent choice and reaction chemistry to accurately control the growth in the NC. All the advantages of 2D colloidal NCs will be exploited to fabricate solar cells in low cost while retaining efficiencies towards 10%. The objectives of this proposal are as follows: Develop colloidal synthetic routes for 2D colloidal NCs. Balance the reagent choice and ligand chemistry to achieve NC growth with controllable size, shape, and particularly thickness. Assemble 2D colloidal NCs to device scale area and perform correlative material studies with electronic properties (carrier lifetime, photoluminescence, carrier mobility). Fabricate all-inorganic NC solar cells and optimize in the device parameter space towards high power conversion efficiency. The project will be divided into three work packages (WPs) with a number of tasks in each WP structured to achieve the aims and objectives. Work Package 1 Controllable synthesis Task 1.1 Develop colloidal synthetic routes to 2D semiconductor NCs. Hot-injection method which involves the injection of a cold solution of precursor molecules into hot liquid will be employed due to the instantaneous formation of nuclei with slow growth of the existing nuclei but not to new nucleation for well controlled size and thickness. The product will be separated by centrifuging and washed up for characterization and analysis by XRD, electron diffraction and HRTEM for structure, and EDS and Raman for chemical composition. Task 1.2 Monitor and control the thickness, doping and their effect on the optical properties. Unlike 0D and 1D NC, in addition to control over composition and structure of 2D NCs, of particular interest is to rationally design and tune the thickness-dependent optical and electronic properties. For example, few-layer MoS2 has an indirect bandgap, but when it is thinned to single-layer, it becomes direct bandgap leading to enhanced photoluminesence. In this task we will monitor the effects of the thickness distribution particularly on absorption and photoluminescence (lifetime and QY). The latter will also be used as a metric to decide on the more promising routes for device fabrication, focusing on highly PL materials as the most promising candidates. In addition, substitutional or interstitial doping of metal sites within 2D NC may be employed to engineer optical characteristics. Work Package 2 Optoelectronic Properties of NC solids The presence of covalently bound ligands on the surface of colloidal NC provide a versatile synthetic handle for tailoring the structure, stability, and importantly electronic and optical properties. The deviation of composition and atom arrangement along the terminating edge and corner sites of 2D colloidal NCs also offers another way to tune their properties. One of the key determinant factors of the performance of solar cells is the carrier mobility. In this task we will investigate ligand exchange strategies using ligands that are shorter than 0.3 nm and contain functional head groups such as di-thiol groups and carboxyl-acid based groups. At the same time those functional groups should serve to passivate dangling bonds and therefore their electron-donating density will be chosen accordingly. We will monitor the effect of those ligands on carrier mobility by performing CELIV measurements in diode structures resembling an actual solar cell device architecture as well as using FET mobility measurements. In addition to high carrier mobilities NC solids for efficient solar cells call for long carrier lifetimes. Such long lifetimes can be achieved by suppressing trap states and recombination centers typically caused at grain boundaries and interfaces. The role of this task is to monitor the degree of passivation of the ligands utilized with Photoluminescence and PL-lifetime measurements. Work Package 3 Photovoltaic device fabrication, testing and optimizing Task 3.1 We will develop simple Schottky and bilayer heterostructures in which the sole photoactive layer is the 2D NC which can be achieved by using a transparent n-type high bandgap semiconductor to form a junction. We will then perform carrier lifetime and recombination-rate characterization employing transient photovoltage and photocurrent measurements. Task 3.2 Optimization of heterojunctions based on 2D NCs. We will perform a device optimization study in which we will study the effect of layer thickness and contact selection to maximize efficiency. The optimized thickness will be sought as a combination of the expected carrier diffusion length and achievable depletion widths based on the mobility, lifetime and carrier density of the semiconductor. Appropriate contacts will be investigated based either on inorganic (MoOx) or organic hole transport layers (electron blocking layers).

Personal Narrative - My University Education Essay -- Personal Narrati

My University Education When I decided to attend State University, I pictured university education as an "Ivory Tower". I thought that I would be able to drown myself in my studies and not be affected by everyday life. Boy was I wrong. I found out in the fall of my freshman year that university education isn't the Ivory Tower that I pictured it to be. I was working 32 hours each week and attending classes full time and therefore, didn't have the time to devote to my studies that I had wanted to. When I look at my university education now, I can picture it as a trip that a family takes in the car. It's full of things that you want to see, things you don't want to see, and things you don't care about. The family begins the trip by planning where to go and what to do. Similar to a university education, a person plans what major to pursue and what classes to take. Just as travel plans always change, university plans always change. The major that was chosen changes to a different major and classes that the student planned to take are exchanged for other classes. Before th...
