Comparison of Global Cities Essay Example | Topics and Well Written Essays - 2250 words

Comparison of Global Cities - Essay Example New York outclasses all other cities in the world because it has an extremely diverse population and over the years, it has become the financial hub of the world. Wall Street, New York Stock Exchange, and the offices of Fortune 500 companies make it impossible for the business world to deny its importance. London has an edge when it comes to cultural heritage because it attracts the largest number of foreign visitors from the entire world on the same basis. Furthermore, there is no denial to the financial importance of the city since it is the heart of Europe and the entire world in terms of its financial and economic activities. United Kingdom is an important force in the world affairs and global political arena thus making allowing London and impeccable role in global politics. Tokyo could be called as the New York or London of Japan. Since the Second World War, the city has witnessed unprecedented economic growth, which continues even as of today. With offices of more than 50 Glob al 500 companies in Tokyo, Tokyo Stock Exchange is the third largest stock market in the world in terms of market capitalization. Tokyo lags behind when it comes to attracting tourists and increasing the diversity in the society by welcoming immigrants. The debate of global cities is never ending. As mentioned earlier, even as of today, experts have not been able to agree on a single definition of a global city. Furthermore, it is rather complicated to assign a quantitative value to each of the factors that characterize a city as a global city. Quite understandably, with the rapid pace of globalization, it is highly likely that these cities will witness a few serious contenders for the top spots in the global cities lists.

Parenting Capacity and Substance Misuse Essay Example | Topics and Well Written Essays - 8000 words

Parenting Capacity and Substance Misuse - Essay Example Because these effects within the children have a strong potential to be carried into the next generation as well as to impact the public health, it is necessary for the social worker to learn how to recognize these signs and develop means of providing the children with the needed elements they are missing within the home. While this seems a nearly impossible task without the investment of vast resources and time into each family unit, there are some tools and practices that may help. It is the purpose of this study to examine the prevalence of these issues within society and to illustrate the importance of understanding on the part of the social worker in bringing about positive effective change within the home. It seems to be almost common knowledge that substance abuse/misuse can have serious detrimental effects on the care and raising of children within the home where one or both parents are involved in substance abuse activity. The tendency of this thinking holds that all children living within homes in which substances are used or abused are the victims of domestic violence. However, children living in these types of situations may not have any experience at all with the concept of violence within the home, yet may have numerous other issues to deal with as a result of neglect or other forms of abuse. Parents engaging in substance abuse may not have enough time or attention to provide their children with the necessary skills and attention they require to thrive while the parents may also be spending much-needed time and money away from the home as a means of supporting their habit. Children living in this sort of environment may find themselves needing to survive without adequate cloth ing, food or housing while also being required to essentially raise themselves without the benefit of parental guidance or support. This situation can have serious public implications as teenagers, having grown up in this sort of environment, tend to have

LAW FOR BUSINESS Assignment Essay Example | Topics and Well Written Essays - 1250 words - 1

LAW FOR BUSINESS Assignment - Essay Example Thus the law on tort has allowed and provided compensation in respect of economic losses that arise directly out of the physical loss, which has not been problematic, but there have been instances when a causal link with the injury and the economic loss could not be made. (Pritchard v. Cobden)1. The problem that lies is in the compensation for losses which are financial or pecuniary in nature, or in other words the loss cannot be in any attributed to or have no connection whatsoever with the personal or physical harm that has been caused to the claimant, this is what has been termed as pure economic loss. These type of losses can include the financial loss or expenditure which resulted from the negligence of the defendant. Therefore for the majority of cases under this head there is an exclusionary rules which bars recovery in these cases and liability is the exception. (Deakin et al 2003) It has been argued that the courts in the instance of personal injury tend to compute loss of f uture earnings which are as difficult to calculate as would be pure economic loss. Furthermore in Canadian National Railway v. ... ment that has been most often cited by the court is that the if the exclusionary rule is not present than the ‘floodgates’ in respect of such liability would open, whereby there would endless claims against the defendants. This has been argued to be a weak argument because extensive liabilities can be found in respect of claims of physical damage for example large scale pollution. (Elliott et al 2007) A better argument in that respect would be the fact that if such an open ended duty of care is imposed in respect of economic loss then there remains the danger of indeterminate liability that is unpredictability in respect of the number of claimants as well as the size of claim. An important example that has been given in this respect is where due to an accident on the highway the motorist who was negligent is held to owe a duty to all those who were stuck in a traffic jam as a result of the accident in respect of their loss of earnings. (J.Stapleton, ‘Duty of Care a nd Economic Loss- A Wider Agenda’)3. Therefore a line of exclusion has been drawn. There has been an argument from Professor Feldthusen that all cases in respect of pure economic loss should not be covered under one heading and therefore a disctinction in this respect should be made for each area. Question 2Â   In the case of Hedley Byrne v. Heller4 the courts did not find any negligence misstatement because of the fact that there had been a disclaimer in the remarks that is the term without responsibility whereby the possibility of a duty of care was extinguished.The position in respect of accountant’s liability can be seen from the decision of House of Lords in Caparo v. Dickman5 whereby for the establishment of a duty of care a reformed three stage test was laid down. The first requirement was

Macbeth explores ambition and its consequences Essay Example for Free

Macbeth explores ambition and its consequences Essay Macbeth explores ambition and its consequences and I am going to show how he successfully portrays this exploration and where in the play examples of this can be found. In scene three of act one, the witches for the second time in the play are seen. This time they are bragging about their unnatural actions and their powers over the human world. Macbeth and Banquo appear on what Macbeth describes as an unusually, foul and fair day. A foul day would be commenting on the weather but a fair day since they have just been triumphant in a defeat in battle. This description of the day by Macbeth could also mean something else too. It could also represent what is about to happen as well. Fair prophecies are to be told soon, but at the same time they may turn out to be foul. When Macbeth and Banquo confront the witches, they are unsure of what or who they are. Unsure of whether they are mortal or immortal due to the things they are saying and how they appear since they have beards like men. This can be seen when Banquo says, What are these,/ So withered, and so wild in their attire,/ That not look like th inhabitants o th earth,/ And yet ont? Live you, or are you aught/ That man may question? You seem to understand/ By each at once her choppy finger laying/ Upon her skinny lips. You should be women,/ And yet your beards forbid me to interpret/ That you are so. Then each of the witches hail Macbeth in three different ways. The first is Thane of Glamis. The second witch, Thane of Cawdor. The third witch hails Macbeth and speaks of him as King of Scotland thereafter. Banquo then questions the witches as to what they have to say to him. The first two witches build up to the third witchs comment that Banquos descendants will be kings. After this, Macbeth begins to question the witches for more information as to how these prophesies are to come true and how they know this information. All of a sudden the witches vanish into thin air leaving Banquo and Macbeth to talk about what has just happened and what has been said. Ross and Angus (two of Macbeths men) arrive and tell Macbeth of his elevation to Thane of Cawdor, and that the former thane is to be executed for treason. Macbeth and Banquo are in disbelief after being told this since what the witches have told them is really happening. Macbeth is now intent in believing he is to be king due to this occurrence of him becoming Thane of Cawdor. Banquo warns Macbeth that evil is at work even though such good things are being predicted and happening. Banquo is sure there is something sinister behind it all. Macbeth doesnt want to hear what Banquo is telling him and begins to imagine what King of Scotland would mean for him. Macbeth and Banquo decide to let future take care of itself and agree to discuss this matter at a more convenient time. It is already clear that the two men arent in agreement about the situation. Macbeth believes what the witches have told them, since part of what they have already said has come true. Banquo on the other hand is doubtful about what is happening and believes something evil and sinister is happening. Banquo is thinking logically and being very conscious about the current situation. Already ambition and temptation is effecting Macbeths actions and thoughts. Doubtfulness and a disagreement in opinion is the only thing challenging their relationship so far but it could get a lot worse. At this point the reader may feel that Banquo is trying to tell Macbeth to not read too deeply into these prophecies told by the witches since they are believed to be evil by him. But on the other hand Banquo may be regarded as jealous towards Macbeth about his good fortunes that are occurring. I think Banquo being regarded as jealous, is thought of more by Macbeth rather than the reader. Macbeth may see Banquo as a threat since his descendants may challenge Macbeths position in years to come when he believes he shall be king of Scotland. Macbeths ambition within this scene has not yet caused consequences but may do in later scenes to come. When Macbeth enters and Lady Macbeth explains to him what her plans are of killing the king Macbeth does not appear as enthusiastic about the idea and is hesitant. He immediately explains that Duncan will be departing next day. But Lady Macbeth simply says that he shall not see tomorrow and to leave the plans to her. It is understandable for Macbeth not to be all that enthusiastic about the idea of killing the king due to many aspects. These aspects include, Duncan being a relative of Macbeths, the potential of being caught, and also a matter of killing someone just to steal a title which belongs to an ally of his. Ambition from Lady Macbeth seems to be a threat towards Macbeth. Her violent, blistering soliloquies in act one, scene five, testify to her strength of will, which completely eclipses that of her husband. The witches are the cause of Lady Macbeths actions and ideas. Their prophecies have so far influenced both Macbeth and Lady Macbeth, although Lady Macbeth considerably more so at this point within the play. In scene six Duncan arrives at Macbeths castle and is greeted warmly by Lady Macbeth. A very false greeting since the thoughts and ideas running through her mind are far more different than what she is expressing to Duncan in greeting him. This is false sense of security from Lady Macbeth towards Duncan. Ambition is feeding this false sense of security from Lady Macbeth towards Duncan since this is part of her plan to kill the king. Scene seven begins with Macbeth debating to himself the options he has in murdering or not murdering Duncan. He says that the deed would be easy if he could be certain that it would not set in motion a series of terrible consequences. He then considers the reasons why he ought not to kill Duncan. The reasons include: Macbeth is Duncans kinsman, subject and host. For someone to be related to and host someone else, then murder them is seen upon as inconceivable. He then comes to the decision to not kill Duncan since the only thing to drive his actions of killing the king would be his ambition, which he sees as an unreliable guide. Lady Macbeth is now expressing outrage towards Macbeth and trying to gain sympathy from him towards her since she has just told him that he is not providing her with enough love just because he wont kill Duncan. This is a very desperate resort that further expresses Lady Macbeths character towards the audience. Ambition is driving her evil actions. As Macbeth begins to waver after Lady Macbeths insults towards him, she then explains her plan. Immediately after she has explained her plan, Macbeth is surprised by her well thought out plan and her boldness/attitude. He then decides to proceed with the murder. Lady Macbeths attitude and ambition is influencing Macbeth to such an extent as to change his feelings and ideas towards the subject. This emphasises the power of ambition expressed from one person towards another. The witches prophecises and Lady Macbeths ambition together have made Macbeths ideas and opinions change completely. In act two, scene 1, Banquo and Fleance are walking along the hall way of Macbeths castle. Banquo tells his son, Fleance, about him being unable to sleep properly due to cursed thoughts and dreams. This shows that the three witches are having an effect upon Banquo. When Banquo and his son are confronted by Macbeth in the hall way, Banquo speaks of the witches telling some truth. Macbeth replies in an innocent way and says, I think not of them./ Yet when we can entreat an hour to serve,/ We would spend it in some words upon that business Macbeth is telling Banquo a blatant lie about his thoughts and feelings about the witches. Macbeth tells Banquo that he has thought nothing of them since the night they both confronted them. They then both agree to talk about the subject of the witches and their prophecies at a later time. Lady Macbeths plans have made Macbeth lie to his own friend and a great friend of that who he fought with side by side in battle. If Macbeth had told Banquo the truth in that he had been thinking about the witches a lot of the time, Banquo may suspect something when the king is killed in Macbeths own home and then Macbeth becomes king! Banquos knowledge of the witches prophecy makes him both a potential ally and a potential threat to Macbeths plotting. For now, Macbeth seems distrustful of Banquo and pretends to have hardly thought of the witches, but Macbeths desire to discuss the prophecies at some future time suggests that he may have some sort of conspiratorial plans in mind. The appearance of Fleance, Banquos son, serves as a reminder of the witches prediction that Banquos children will sit on the throne of Scotland. We realize that if Macbeth succeeds in the murder of Duncan, he will be driven to still more violence before his crown is secure, and Fleance will be in immediate and mortal danger. Ambition and determination from both Macbeth and Lady Macbeth will drive someone to killing Fleance or Banquo or even both at some point since these characters are potential threats in preventing Macbeth to remaining king of Scotland. As soon as Macbeth and Fleance depart and leave Macbeth alone, Macbeth imagines that he sees a dagger leading/pointing him in the direction to Duncans room. Macbeth tries to grasp the weapon and fails. He wonders whether what he sees is real or a, A dagger of the mind, a false creation,/ Proceeding from the heat-oppressed brain? Macbeth decides that the vision of the dagger was simply a manifestation of his unease over killing Duncan. It is obvious that Macbeth is not overly confident nor enthusiastic about the matter of murdering Duncan but his lover has literally forced him into this position through mockery and ambition. As Macbeth hears the signal of the bell rung by Lady Macbeth he heads off to the kings room and commits the murder and says, I go, and it is done./ The bell invites me./ Hear it not Duncan, for it is knell/ That summons thee to heaven or to hell. This is Macbeths concluding speech before going on to commit the murder of Duncan. In act two at the beginning of scene one, Lady Macbeth is waiting for Macbeth to return, is found contemplating to herself about drugging the kings guards and congratulating herself as to how bold she is to carry out such actions. She also asks herself what gave her such courage, evil or sinister spirits perhaps as she asked for earlier on in the play? She says this at the beginning of scene two act one, That which hath made them drunk hath made me bold;/ What hath quenched them hath given me fire./ Hark! Peace! She obviously doesnt want anyone else to hear what she is saying since she appears startled when Macbeth enters. Macbeth appears dazed and obsessed with thoughts of damnation after committing the murder. Lady Macbeth notices the blood drenched daggers within the hands of Macbeths. She tells him to pull himself together after this dreadful mistake and also shouting, Whos there? What ho! Lady Macbeth warns Macbeth that he may have woken the guards after that silly act of shouting and tells him to return the daggers to the guards as planned. Macbeth refuses and so Lady Macbeth places the daggers next to the guards herself. Effects of shock and disbelief are gradually setting into Macbeth and this can be seen by his type of language spoken. This can be seen when Lady Macbeths tells him to return the daggers and he replies, Ill go no more./ I am afraid to think what I have done./ Look ont again I dare not. Macbeth appears to be unable to face up to what he has done, not even to himself, and is ashamed of himself after carrying out the murder. He is in shock and in denial over the whole situation. Macbeth appears scared and frightened of his own actions and all of this because ambition from Lady Macbeth and Macbeth. As the two go to wash their hands and prepare to get changed into their night clothes there is a knocking on the door of the castle and the murderer and his accomplice frantically get changed so to enable no one to suspect them as the possible murderers. The effect on Lady Macbeth after her trip into Duncans bedroom is particularly striking. She claims that she would have killed Duncan herself except that he resembled her father sleeping. This is the first time Lady Macbeth shows herself to be at all vulnerable. Her comparison of Duncan to her father suggests that despite her desire for power and her harsh chastisement of Macbeth, she sees her king as an authority figure to which she must be loyal. Also after the murdering of Duncan an important aspect to remember is that physical evidence can be washed away, like the blood to be washed off the skin of the hands, but emotional and mental feelings cannot be so easily removed and disposed of. This can be seen a little later in the play when Macbeth begins to act disturbingly and struggles to hold in his feelings. In the first scene of act three, Banquo is summing up the current situation. He has now witnessed two of the witches prophecies coming true, why not the next? If the next prophecy comes true that means Banquos descendants shall become king. Ambition and hope is now feeding Banquos motivation towards believing that the next prophecy shall come true. Macbeth and Lady Macbeth are now attempting to put Banquos mind at ease by inviting him to a feast. Doing this they hope to prevent Banquo getting suspicious about the murder of Duncan and so not think it was Macbeth and Lady Macbeth who were involved in the murder. If they both tried to avoid any sort of contact with Banquo, it would seem suspicious and suspect since he is such a good friend of Macbeths. Macbeth goes onto tell Banquo that they must discuss the problem of Malcom and Donalbain fleeing and therefore possibly intending to plot against the crown. So far, Macbeth is covering is guilt very successfully and appearing genuine and true towards Banquo. A false sense of security is given from Macbeth towards Banquo. When Banquo departs, Macbeth remains on stage and begins a soliloquy. The soliloquy is of Macbeths thoughts about Banquo and the threat he holds with Fleance too. He speaks of how he may have killed Duncan only for their sake in the future to come. He fears killing Duncan has assisted them in becoming king a lot sooner than Macbeth wants. Macbeths best friend is now is worst threat. Banquo and Fleance are a great threat towards Macbeths position of kingship. Macbeths and his Ladys ambition for wanting everything and nothing but the best in kingship is beginning to have its consequences. Macbeth now knows he must get rid of both Banquo and Fleance so to prevent any such threat remaining towards Macbeth and his position as king of Scotland. He speaks with two murderers to whom he had already spoken the day before, assuring them that their misfortunes are Banquos fault. He tries to urge them to take revenge upon Banquo and his family. He tries to persuade the two murderers that if they carry the intended job out, that then proves them to be real men. They agree to the proposed job Macbeth is telling them to do and he stresses to kill both of them, Banquo and Fleance. Macbeth is now needing more people killed (to feed his ambition and determination in becoming king) although not carrying the offence out himself. This may be due to the fact that killing Duncan is taking effect and that Macbeth can not bear to kill another friend of his just for his good. This killing is an act of selfishness, greediness and desperation. He may not be carrying out the murder himself because he feels he is unable to kill such a dear friend and a friend he has fought side by side with in battle. He also may not want to murder Banquo and Fleance because it may appear suspicious if another murder occurs and no witnesses available to say where Macbeth was at the time. If people know where Macbeth is, they cannot suspect him of being guilty for the murder. Macbeth doesnt want to risk being caught by anyone and so has appoint these two men to do the job for him. Macbeth has no hesitation in killing Banquo and Fleance, which shows his ambition and determination is driving his actions. Macbeths conscience is no longer a part of his decisions he makes. Ambition appears to have replaced common sense. He is organising the death of one of his best friends and his friends son just so he can remain as king. Its hard to believe that the murders Macbeth is responsible for (in carrying out and planning) have all been down to prophecies told and Macbeths and Lady Macbeths ambition and determination in making the prophecies happen. Macbeth now appears more able and independent, since Lady Macbeth has had no say in the plan of killing Banquo and Fleance, that we are aware of. Lady Macbeths ambition and determination earlier on in killing Duncan is now consequently making Macbeth more determined to remain king. This is an awful consequence due to the fact that innocent friends and relatives of Macbeths are dying just so Macbeth and Lady Macbeth can preserve their hierarchal status. These are very selfish and ambitious ways of keeping it their own way, the way they want it to be. In scene two, act three, Lady Macbeth is urging Macbeth to put the past behind him due to being uneasy about how Macbeth is. Macbeth hints that he has a plan that is intended to be carried out that evening. He gives no details but he believes she will approve of his plans and actions. Macbeth, through Lady Macbeths eyes, is now appearing to be in full control of making sure that he remains king and she remains queen of Scotland. It is clear that Lady Macbeth is uneasy about it, but she covers her feelings when around Macbeth. After all it was her motivation and ambition that has made Macbeth what he is now both king but at the same time a ruthless killer if needs be just to hold the current position of king. It is clear now that Macbeths ambition is feeding his motivation. In scene four, this is where it all starts to go wrong for Macbeth and for Lady Macbeth too. Macbeth learns that only Banquo was murdered and Fleance escaped from the attempt at killing both. Macbeth is angered at this result and tells himself, There the grown serpent lies;/ the worm thats fled Hath nature that in time will venom breed He basically talks of how Banquo (the grown serpent) lies dead but the younger and growing boy, Fleance (the worm) is still at large and later in life he will pose a threat. Shakespeare refers to the pair as snakes and worms due to the fact that they can strike at any time and are hard to kill or catch. This sums up Fleance perfectly since he could strike at any time and therefore pose a threat, and also is hard to kill. This is disastrous for Macbeth and Lady Macbeth because it is Fleance that must be killed since he is the main threat towards Macbeths kingship. If Banquo survived suspicions would arise, but with Banquo dead and Fleance still alive, suspicions are still going to occur and also the threat is still at large for Macbeth and his lady. As the banquet begins and Macbeth sits down with his friends to eat he finds a ghost of Banquo sat in his seat. Invisible to anyone else at the banquet, Macbeth begins to talk to the ghost in the chair although through the eyes of the people attending the banquet it would appear to be Macbeth talking to a chair. If he starts saying too much he may give away information about murders that they have planned and carried out to the other guests. The side effects of the deception, ambition and lies are now beginning to take effect on Macbeth. He is hallucinating images of his victim which means he is worrying about the matter a great deal. All this is a consequence of over ambitious actions carried out by both Lady Macbeth and Macbeth himself. Shakespeare fundamentally shows ambition in two different ways in Macbeth. He shows how ambition can have dreadful consequences and how it can ruin your life. In Macbeths case he dies which is the ultimate price to pay for his ambition and attempting to change natures course. Shakespeare also shows ambition as a good thing through Banquos actions as he stays level headed and lives life each day at a time. Banquo and his role in Macbeth represent the better side of ambition but Macbeth represents the worst side of ambition. Ambition is generally looked upon as a good aspect to a person, but Shakespeare successfully shows how ambition can be both good and bad and what consequences can occur if you have too much of it in Macbeth.

Belief in a God is necessary for a moral society Essay -- essays resea

Belief in a God is necessary for a moral society Religion in the world has always been considered a rather important aspect of society. Although this is true, there are still people that question the existence of God. A survey done among 1000 people showed that 65 percent of Americans believe that religion is losing its influence on American life (Sheler, 8). Even so, Belief in a God is necessary for a moral society because since the beginning of history man has always made up some sort of role model to explain events and situations that seem inexplicable, God gives people a sense of comfort and hope to know they aren’t alone, and when a society believes in a God, there is a religion behind it that gives ethics and values that they must comply to. Historically, the world has always used a higher being for a reason for the events that occur in their lives. They would look upon the bible to find answers from God or they would just use prayer to find them. The bible has always been used for the purpose of spreading the word of God. However, it is looked at in many different ways. Technically it is said to be the actual word of God to be taken literally, word for word. Historically, the bible was a book written by the existing disciples of Jesus Christ, the son of God who is said to be the Savior (Sheler, 8). For the most part the bible isn’t interpreted that way anymore. People consider the bible to be a book that is full of the inspired of word of God, but something not to b...

Examining a Business Failure – Tyco

Examining a Business Failure – Tyco Examining a Business Failure – Tyco Introduction This paper will describe how specific organizational behavior theories could have predicted the failure Tyco International (Tyco). This paper will discuss the contributions of leadership, management, and organizational structures to the organizational failure of Tyco. Organizational Behavior Organizational behavior is a field of study, meaning that it is a distinct area of expertise with a common body of knowledge.Organizational behavior studies three determinants of behavior in organizations: individuals, groups, and structure. In addition, organizational behavior applies the knowledge gained about individuals, groups, and the effect of structure on behavior in order to make organizations work more effectively. Organizational behavior is concerned with the study of what people do in an organization and how their behavior affects the organization’s performance (Robbins & Judge, 2 007).In the case of Tyco, the organizational behavior of the company in 2002 was unethical in nature. Tyco's former CEO Dennis Koslowski, former CFO Mark Swartz, and former General Counsel Mark Belnick were accused of giving themselves interest-free or very low interest loans (sometimes disguised as bonuses) that were never approved by the Tyco board or repaid. Some of these â€Å"loans† were part of a â€Å"Key Employee Loan† program the company offered. They were accused of selling their company stock without telling investors, which is a requirement under SEC rules.Koslowski, Swartz, and Belnick stole $600 million dollars from Tyco through their unapproved bonuses, loans, and extravagant â€Å"company† spending. Rumors of a $6,000 shower curtain, $2,000 trash can, and a $2 million dollar birthday party for Koslowski's wife in Italy are just a few examples of the misuse of company funds. As many as 40 Tyco executives took loans that were later â€Å"forgivenà ¢â‚¬  as part of Tyco's loan-forgiveness program, although it was said that many did not know they were doing anything wrong.Hush money was also paid to those the company feared would â€Å"rat out† Kozlowski. Essentially, they concealed their illegal actions by keeping them out of the accounting books and away from the eyes of shareholders and board members (http://money. howstuffworks. com/cooking-books9. htm). In an organizational world characterized by cutbacks, expectations of increasing worker productivity, and tough competition in the marketplace, it is not surprising that many employees feel pressured to cut corners, break rules, and engage in other forms of questionable practices.What constitutes good ethical behavior has never been clearly defined. Employees see people all around them engaging in unethical practices. (Robbins ; Judge, 2007). Leadership Failure The senior managers at Tyco failed as leaders. They forgot that leadership was about serving others and no t themselves. But it was also a failure of those who followed the leaders such as the corporate lawyers who failed in their duty to keep the leaders in check. Tyco lawyers wanted to please their bosses; instead they should have stepped in when corporate corruption was evident. Most of the people who became infamous for their misdeeds ; helip; were not evil people,† said William Lytton (general counsel for Tyco in 2002). As Lytton sees it, they lost sight of the cultural boundaries, blinded by their own career advancement goals. That is where the role of the corporate lawyer becomes critical. While it might prove difficult to stop bad things from happening, â€Å"Sometimes, you do need to just say no† (http://www. vermontlaw. edu/x7845. xml). Management FailureTyco’s top executives ignored their responsibilities to the laws governing corporate management; ignored responsibilities to their investors and ignored responsibilities to their employees. The planning and management strategies of these executives seem to have been more focused on personal gain than on the best interests of the company and its shareholders. As a result of their greed and fraudulent activities, the top executives at Tyco were indicted and convicted of fraud charges for improper accounting practices as well as unauthorized use of company funds for personal gain.One viewpoint on leadership is that it occurs only when people are influenced to do what is ethical and beneficial for the organization and themselves. This definition of leadership does not include influence attempts that are irrelevant or detrimental to followers, such as a leader’s attempts to gain personal benefits at the followers’ expense (Yukl, 2006). In the case of Tyco, when Ed Breen took over as CEO, he fired 290 of the 300 managers who were employed at Tyco during the Kozlowski era along with the other senior managers.He wanted to bring in new management and employees who would help build Tyco’s reputation up and create an ethical firm that consumers and shareholders could trust again. Organizational Failure While the organization was not solely to blame for Tyco’s failure, Tyco could have taken preventive measures which would have avoided this situation entirely, such as: o created codes of ethics to guide employees through ethical dilemmas o implemented policies for enforcing those codes create a corporate governance department and hire experienced professionals to ensure compliance with federal and state regulations are adhered to o offer seminars, workshops, and similar training programs to try to improve ethical behaviors Today’s manager needs to create an ethically healthy climate for his or her employees, where they can do their work productively and confront a minimal degree of ambiguity regarding what constitutes right and wrong behaviors.In upcoming chapters, we’ll discuss the kinds of actions managers can take to create an ethi cally healthy climate and help employees sort through ethically ambiguous situations. We’ll also present ethical-dilemma exercises at the end of each chapter that will allow you to think through ethical issues and assess how you would handle those (Robbins ; Judge, 2007). Summary In 2002, Tyco was controlled by unethical businessmen more interested in personal gain than creating a successful company that shareholders, employees and consumers could trust, respect and benefit from.They failed as leaders and managers; and as a result, made the organization as a whole suffer. They acquired businesses quickly, falsified accounting records, took out personal loans, withheld information from the public as well as shareholders, and caused the market share of the company to drop dramatically. All of this unethical business activity could have been avoided had an official corporate governance department been in place and a company code of ethics policy implemented.References Robbins, S .

Electrochemistry experimen Essay

Introduction: Redox reactions are reactions where the oxidation states of the atoms change. The atoms are either oxidized or reduced, depending if they lose or gain electrons. Electrochemical cells are devices that cause a current from redox reactions. It is set up so that electrons lost from one of the reagents can travel to another reagent. This creates a voltage, which is also known as the electric potential difference. This voltage can be read if a high-resistance voltmeter or multimeter is connected to the circuit. Salt bridge is used to allow migration of ions between two electric cells to maintain neutrality of solutions. It is usually made up of a filter paper moistened with an inert solution or an inert solution/gelatine salt bridge to prevent oxidation of certain ions. This experiment is divided into 2 parts: part A and part B. Part A Objective: To investigate the effect of change in lead(II) ion concentration on the potential of the Pb2+(aq) |Pb(s) electrode Introduction: This experiment investigates the e. m. f. of the cell: Cu(s) |Cu2+(aq) |Pb2+(aq)|Pb(s). Keeping the ion concentration in the copper electrode system constant(1M) and varying the ion concentration in the lead electrode system, the effect of change in lead(II) ion concentration on the potential of electrode as well as the Kc of the above reaction can be found. Chemicals: Copper foil x1, lead foil x1, 1M Cu2+ solution, 0. 1M Pb2+ solution, saturated potassium nitrate solution Apparatus: 250 cm3 beakers, 50cm3 beakers multimeter, distilled water bottle, filter papers, electrical wires with electrode holders, forceps, 100ml volumetric flask,10ml pipette x2, dropper Procedure: 1. The 0. 1M, 0. 01M, 0. 001M, 0. 0001M Pb2+ solutions were prepared from 0. 1M Pb2+ solution by dilution(1 portion solution plus 10 portions water). 2. The copper and lead electrodes were cleaned with a sand paper. 3. The circuit was connected as the diagram below. 4. The e. m. f. was recorded when the data shown was stable. 5. The above steps(2-4) were repeated with 0. 01M, 0. 001M and 0. 0001M Pb2+ solutions. Safety precaution: Potassium nitrate solution: Contact with combustible material may lead to fire 1M Copper(II) sulphate solution: harmful and irritating to eyes and skin. –>Safety goggles should be worn. Experimental set-up Results: [Pb2+]/M log[Pb2+] E/V 0. 1 -1 0. 482 0. 01 -2 0. 502 0. 001 -3 0. 521 0. 0001 -4 0. 545 Graph of E against log [Pb2+]: Trend shown: Given the ion concentration in the copper electrode system constant, it is found that the potential of the cell drops as the lead(II) ion concentration increase. The electrode potential is inversely proportional to the ten folds of ion concentrations. Calculation: When the reaction Cu2+(aq) + Pb(s) –> Pb2+(aq) + Cu(s) achieves equilibrium, the net e. m. f. of the cell=0 volt. The equilibrium expression of this reaction is: Kc= [ Pb2+(aq)][ Cu(s)] /[Cu2+(aq)][ Pb(s)] The effective concentration of Pb(s)/ Cu(s) are independent of its amount present and can be considered as constant. This reduces the expression to Kc= [ Pb2+(aq)] /[Cu2+(aq)] = 1Ãâ€"1021 Conclusion The potential of the cell decreases ad the ion concentration of Pb2+ increases. Further Analysis: Using the Nernst equation: E=E? -0. 059/n log[ox]/[red], Take [Pb2+]=0. 1 M as an example, E=0. 47-0. 059/2 log(0. 1/1)=0. 4405(V) [Pb2+]/M log[Pb2+] E/V(calculated) E/V(measured) %difference 0. 1 -1 0. 4405 0. 482 9. 42% 0. 01 -2 0. 529 0. 502 5. 10%.0. 001 -3 0. 5585 0. 521 6. 71% 0. 0001 -4 0. 588 0. 545 7. 31% It is shown that difference is present between the calculated value and measured value. This may be because of different conditions, resistance of the multimeter or errors in preparation of various concentrations of solutions. Part B Objective: To find out the equilibrium constant by e. m. f. measurement Introduction: The equilibrium constant for the below reaction is found out: Ag+(aq) + Fe2+(aq) Fe3+ (aq) + Ag(s) By e. m. f. measurement on the cell Pt |Fe2+(aq), Fe3+(aq)|Ag+(aq)|Ag(s) Chemicals: 0. 1 M Fe3+ solution, 0. 2 M iron(II)sulphate, 0. 2M barium nitrate, 0. 4M silver nitrate, platinum electrode, silver electrode Apparatus: gelatine salt bridge, 250 cm3 beakers, 50cm3 beakers ,multimeter, distilled water bottle, electrical wires with electrode holders, forceps, 10ml pipette x2 Procedure: 1. Equal volumes of 0. 2M FeSO4 and 0. 2M Ba(NO3)2 were mixed and the precipitate was allowed to settle without disturbance. 2. Equal volumes of 0. 1M iron(II) nitrate solution obtained and the iron(III)nitrate solution were mixed. This was the Fe2+(aq)/Fe2+(aq) half-cell. 3. The 0. 4M, 0. 2M, 0. 1M, 0. 05M, 0.025M silver nitrate solutions were prepared from 0. 4M silver nitrate solution by dilution. 4. The silver electrode was cleaned with a sand paper. 5. The circuit was connected as the diagram below. 6. The e. m. f. was recorded when the data shown was stable. 7. The above steps (4-6) were repeated with 0. 2M, 0. 1M, 0. 05M, 0. 025M silver nitrate solutions. Safety Precaution: Silver nitrate: harmful and oxidizing; 1) Poisonous if swallowed or inhaled 2) Skin contact with silver nitrate solid or solutions is likely to leave silver stains on the skin. Barium nitrate is poisonous and very harmful if swallowed. It is also a strong oxidizer, so may be hazardous if mixed with flammable materials. Experimental Set-upResults: [Ag+]/M log[Ag+] E/V 0. 4 -0. 398 0. 023 0. 2 -0. 699 0. 005 0. 1 -1 -0. 030 0. 05 -1. 301 -0. 050 0. 025 -0. 025 -0. 053 Graph of E against log[Ag+(aq)]: Calculation: When the reaction reaches equilibrium, both forward and backward reactions proceed to the same extent. This means that both the half cell reactions would have the same potential to proceed, so that the net e. m. f of the cell =0 volt at equilibrium. From the graph, the x-intercept is log[Ag+(aq)]=-0.72, hence,[Ag+(aq)]eqm=0. 1905 Ag+(aq) + Fe2+(aq) Fe3+ (aq) + Ag(s) KC= [Fe3+ (aq)]/ [Ag+(aq)][ Fe2+(aq)] =0. 1/ (0. 1905X0. 1) =5. 2493(mol2dm-6) ~5. 25(mol2dm-6) Conclusion: The equilibrium constant for the reaction between Fe2+/Fe3+ and Ag+ is 5. 25 mol2dm-6. Discussion(for both parts): 1. Possible Errors: -The electrodes (Cu(s),Pb(s),Ag(s)) were not cleaned very well with a sand paper so that they are not conducting electricity in all parts. The e. m. f. measured may hence be underestimated. -The same ammonium nitrate/gelatine salt bridge was used several times in part II of experiment. Ions of previous measurement may remain in the salt bridge and change the concentration of ions in the next measurement. -The apparatus including pipettes, beakers and volumetric flask may not be washed to be very clean. The error in concentration may be enormous when handling very dilute solutions (e. g. 0. 001M, 0. 0001M, 0. 025M) -The electrode touched the salt bridge once so that the accuracy of measurement of e. m. f. was affected. The solution is not exactly passed. -Air gap may be present in the ammonium nitrate/ gelatine salt bridge, increasing the resistance of ion migration. 2. Difference in effect of ion concentration on electrical potential of cell: -In part A, the cell e. m. f. increases as [Pb2+(aq)] decreases. However, in part B, the e. m. f. drops as [Ag+(aq)]. This suggests that when the species is a stronger oxidizing agent in the reaction and undergoes reduction, the presence of its ions tends to increase the e. m. f. whereas the one which undergoes oxidation tends to reduce the e. m. f. The species with more positive standard reduction potential has a positive effect but the one with less positive potential has a negative effect.
