A critical review on current debates about the effectiveness of self regulation of the UK press using the News Of The World as a case study The WritePass Journal
A critical review on current debates about the effectiveness of self regulation of the UK press using the News Of The World as a case study Introduction A critical review on current debates about the effectiveness of self regulation of the UK press using the News Of The World as a case study . The failure of self-regulation Perhaps the most significant condemnation of self-regulation stems from the current unethical (and illegal) practices which some journalists choose to engage in. Leading the way in underhand investigatory techniques was the tabloid paper NoW. Described by its owner James Murdoch as a crime fighter, it had a reputation for celebrity scoops and check-book journalism (08.07.11, BBC News). It was the desire to satiate its readership’s interest in this type of story which ultimately pushed it to commit serious violations of privacy. The first indications that it was engaging in phone hacking emerged in 2005 when the newspaper printed a story about a knee injury incurred by Prince William. Suspicions were raised as to how this information had been obtained and eventually the author of the article and an investigator from the paper were arrested and imprisoned for illegal phone hacking. To date the police have identified potentially 6,000 victims demonstrating the widespread extent o f this of crime (28.02.12, BBC News). Unable to sustain credibility the NoW closed in July 2011 under a torrent of allegations. The paper has had to pay out millions in damages to those whose privacy they compromised, including  £2million to the parents of Milly Dowler after it emerged that one of its journalists had tapped into the missing girl’s voicemails 28.02.12, BBC News). The inability of the Press Complaints Commission to prevent this type of journalistic behaviour, which reaches beyond the NoW, stems from a variety of factors. Unpacking current debate on self-regulation gets to the heart of these. Current debate over self-regulation In consequence of this scandal in November 2011 David Cameron convened the Leveson Inquiry to investigate the culture, practice and ethics of the press (24.04.12, BBC News). One of the findings that has emerged from the inquiry is that the Press Complaints Commission needs reforming. Lord Black, chairman of the body which funds it, told the inquiry that phone hacking has demonstrated that this institution lacks the investigative powers and the leverage needed to enforce editors to uphold their Code of Practice and apply punitive sanctions (01.02.12, BBC News). In a move which pre-empts the inquiry report the Press Complaints Commission announced in March 2012 that it would be closing and an interim body would take over until a new framework for a regulatory power can be put into place. This apparent failure of self-regulation has reignited the familiar debate as to how exactly the press should be regulated; can they be relied upon to implement it themselves or should some form of statutory regulation be resorted to? Cameron has indicated that the latter situation is not one he favours given that government regulation of the media does not lead to a free media (06.09.11, BBC News). He has not ruled out the idea however that independent regulation might function better if it was inaugurated through statute but kept removed from the government (06.09.11, BBC News). This would produce a body that is not dissimilar to Ofcom, which was created through statute and charged with overseeing the compliance of TV and radio to a code of practice. It is also an institution which firmly believes self-regulation can work for the press providing its governing council has ‘effective powers of enforcement and sanction’ and ‘genuine powers of investigation’ ( O’Carroll, The Guardian, 2012). Ofcom too believes that if self-regulation is to be viable then some aspects of it, particularly the rules governing membership, may have to be upheld by statute (O’Carroll). Other contributors to the ongoing debate about self-regulation have identified alternative aspects of the regulatory process which might be more effective if enforced by law. For instance O’Malley and Soley have argued that there is no reason why there should not be laws that guarantee the right to correction of factual inaccuracies in the press (O’Malley and Soley, p.2). Conservative MP George Eustice has come forward to say that a clearer privacy law which unequivocally balances the right to privacy against the right to freedom of expression would benefit both the public and the press (Eustice, The Guardian, 2012). Not everyone sees the phone hacking scandal as a failure of self-regulation. The Guardian’s Gill Phillip points the blame at internal management and the police for not investigating evidence they first obtained in 2006 (Phillips, 2012). The Press Complaints Commission, Phillips argues, was not designed to address criminal conduct (Phillips). If this situation was to be dealt with through more top-down regulation the result would be heightened complexity which would do no more than obscure the public’s rights and the press’ responsibilities(Phillips). Belsey certainly concurs with this standpoint arguing in Britain the media are already curtailed by the criminal laws of, to name a few, official secrets and sedition, by the civil laws of libel and breach of confidence, and as well as through the use of interlocutory or ‘gagging’ injunctions (Belsey, 1992, p. 6). Adding privacy to this list would have a damaging effect on journalism whilst in all likelihood having no impact on the gossip of tabloids. Furthermore legal restriction on the press will not only curb its democratic role but will also increase the instances when a journalist if faced with the dilemma of acting either legally or ethically (Belsey, p. 8; Harriss, 1992, p. 68). Conclusion – the way forward for self-regulation Self-regulation has been and continues to be undeniably flawed and this is typified by the activity of the NoW. This has been recognised and a significant overhaul of the system is on the agenda. Lord Hunt has proposed that the successor to the Press Complaints Commission should have two arms; the first should address complaints and mediation, the second should operate as an auditor which enforces standards and adherence to the editors’ code. Additionally a more pronounced effort should be made by newspapers internally to self-regulate through the appointment of individuals responsible for compliance (Greenslade, The Guardian, 2012). This would create a regulatory body which has the ability to demand a continued and unwavering commitment to ethical journalism. Ofcom too are confident that if this new body has a robust framework and the authority to impose sanctions on wayward newspapers, effectual self-regulation could at last be overseeing the activity of the press (Oâ₠¬â„¢Carroll). The case of the Press Complaints Commission illustrates that voluntary self-regulation has been little more than a token effort at control over the industry. The blame for this, Tunstall suggests and events corroborate, is with the government for not finding the courage to insist on a compulsory system (Tunstall, 1996, p. 391). In all likelihood the press may have to reconcile themselves with the idea that their membership to this yet undecided regulator will be made obligatory by law. Arguably it would be this new system which differentiates the upcoming regulator from those which have fallen in its wake, and differentiation is certainly needed if the same failures of the past are not to be repeated.

Demand for Bonds Essay Example | Topics and Well Written Essays - 1000 words
Demand for Bonds - Essay Example Thus there will be a windfall loss if bonds are purchased. Thus, bond demand will be low. This also implies that if expected future bond prices are high, then the demand for bonds will rise and vice-versa. iv) Expected inflation: Expected inflation has an adverse impact on bond demand. If there is an increase in expected inflation, bond demand will fall and vice versa. v) Relative risk: If the risk associated with a bond increases relative to other assets the demand for that bond will fall. Analogously if there is a decline in the relative riskiness of a bond, its demand will increase. vi) Relative liquidity: If there is an increase in the relative liquidity of a bond, i.e., if converting the bond into cash becomes relatively easier, the demand for it shall rise if other things remain the same and vice versa. vi) Business-cycle movements: If the economy is undergoing a boom, there will be an increase in the demand for bonds. Similarly, the demand for bonds will fall if the economy is suffering a recessionary period. b) Analyse the following statement: â€Å"This week, the yield on the US Treasury note closed below 3%, a level not seen in 50 years. In the UK, the 10-year Gilt yield sits below 4% for the first time since 1961, according to UBS. Germany’s Bund yield is closing in on 3%. ... This time, the threat of delfation is being taken more seriously. Should policymakers again avert that fate, bond yiels may be primed for an explosive rise as fiscal spending plans and the expansion in money supply suggest inflation is the likely outcome†. [Source: Financial times 28-Nov-2008] Before commenting on the report it will be useful to note that as mentioned above bond demands (and thus investment) are induced by business cycle booms and dissuaded during recessions. However, during booms since the threat of inflation looms large, it is a natural counteracting force to the possibility of overinvestment. Similarly, during recessions, the adverse effect on the demand for bonds can be countered by the threat of deflation. Now, let's turn to the report. The first and foremost point to note in this context is the date of the report. It is dated November, 2008. Thus the US, UK and the German economies were in recession, arguably the worst one since the great depression (This was during the heart of the global financial crisis). Thus, one should expect expansionary monetary policies during this time. Lower interest rates ideally stimulated investment demand and thus increase the effective demand which leads to an expansion in real aggregate output with a multiplier effect and thus employment as well. What is reported seems to be along the same lines of intention. The current yields on US Treasury note fell to a level that was a precedent in 50 years. Similarly there was a decline in long term yields in the UK economy (gilt) and Germany (bund yields). However, in order for this policy to work, the falling bond yields

The math behind the Pendulum Research Paper Example | Topics and Well Written Essays - 2250 words
The math behind the Pendulum - Research Paper Example As the period of a pendulum is constant, pendulums were used to regulate the movement of clocks. Until the 1930’s pendulums were the most accurate time keeping devices of the world. In 1583, the Italian scientist Galileo first noted the constancy of a pendulum’s period by comparing the movement of a swinging chandelier in a Pisa cathedral with his pulse rate. He found that the time was not a function of how wide the chandelier swung. As the wind was blowing the chandelier, it was swinging different distances side to side or amplitudes. Galileo found that the pendulum swung more slowly. Over a shorter swing, the chandelier took just as many of his heartbeats to complete a swing with greater amplitude. Galileo made an error in the calculation of the angle of the chandelier. In 1656, the Dutch mathematician and scientist Christian Huygens invented a clock controlled by the motion of a pendulum (Huygens and the Pendulum, Princeton). The accuracy of mechanical clocks improve d in the span of a couple of decades in the early 17th century from plus or minus half an hour per day to one second per day. This quantum increase in accuracy of timing enabled previously unimagined degrees of precision measurement in mechanics, astronomy and other fields of study. Time then for the first time was expressed as an independent variable in the investigation of nature. For example, each of the following could be reliably investigated for the first time: The effect of force on objects over time The distance of fall over time The change of speed over time The radial movements of planets over time The progress of chemical reactions over time All these investigations required that the time could be accurately and reliably measured. Thus the pendulum held a very important place as a time keeping device. Competent time measurement was a requirement for modern science and the pendulum enabled this to happen (Story behind the science, Web). The pendulum played more than a scie ntific and technical role in the formation of the modern world. It also indirectly changed cultures and societies through its impact on navigation. Position on the Earth’s surface is given by latitude and longitude. A traveler sailing across the sea must know the coordinates of his present position as well the coordinates of his destination. Hence the knowledge of position was essential for reliable traveling and trading. Accurate time measurement was long seen as the solution to the problem of longitude determination which had vexed European maritime nations in their efforts to sail beyond Europe’s shores. Treasure fleets from Latin America, trading ships from the Far East were all getting lost and running out of food and water. The pendulum thus played a pivotal role in resolving the longitude problem and thus holds an important place in Physics as well as History. This thesis will focus on the interesting aspects about the period of a pendulum and its mathematical d erivation. According to Hooke’s law, the restoring force of a spring is directly proportional to its displacement. Fig 1: Physical representation of Hooke’s law The above figure shows a spring elongated through a length x. F is the force that wants to drive the spring back to equilibrium. By Hooke’s law, |F| ? |x| F = -kx where k is the spring constant measured in Newton/metre (N/m) Here, the negative sign represents that the direction of F is opposite to that of x.

Is Immortality Desirable?
Is Immortality Desirable? Abstract In this paper I discuss whether immortality in the physical form is desirable. In accordance with the deprivation account I seek to defend the commonsense view that death is a bad thing for the individual but will argue that consistency and logic does not require me to believe that an immortal existence is to be desired. I defend Bernard Williams claim that with an immortal life we are doomed to an eternity of never ending repetition, boredom and indifference and that death is a necessary evil if we are to avoid a life devoid of freshness. I will also argue that death and the very limitation that its sets down gives life meaning. In support of Victor Fankl I will defend the claim that it is time pressure that shapes our lives. In developing my argument I will oppose the counter argument that it is death that makes life meaningless not meaningful. Is Immortality desirable? Is it simply a design fault that we age and die? Are we living in a culture of death whereby we die simply because we accept it as an inevitability? â€Å"All men are mortal†said Socrates, however, a lifetime spent on in-depth research has led pioneering scientists to deem aging not as an inevitable consequence of the human condition but as a preventative disease. Perhaps these scientists are far too optimistic in their search for a virtual fountain of youth, or is it simply the case that death – the end of the physical being, is accepted by the mind and embraced through reinforced teachings and observation. Whether you believe that a quest for immortality will or will never be achieved is irrelevant to the question at hand. The focus will be on whether immortality is desirable, assuming something can be desired yet impossible. Clarification of what I mean by immortality is essential; I will focus on what can be described as physical immortality- by this I mean that on e can live for eternity as a human physical being on earth (where everyone is immortal). In my interpretation, I will also assume that there is no get out clause, take for example one is offered an elixir of immortal life, once taken a person cannot change their mind opting for death- immortality is forever. My definition will also incorporate a block on aging; eternity will be lived through a perfectly healthy functioning body. Accidents will be possible but can be fixed with ease. Intentionally, I have painted a picture of immortality which may at first glance seem desirable, as one may be quick to argue that an immortal life where a person is forever aging to the point of an eternity of pain and discomfort and where accidents occurred and could not be fixed is simply not one to be desired. However, throughout this essay I will put forward the argument that those who believe immortality to be desirable have made an irrational choice, it would be a mistake to crave an immortal life and take the elixir of eternal existence. I will approach this issue by initially examining Nagels (1970) question of whether it is a terrible thing to go out of existence, I will agree and defend the deprivation account of the evil and badness of death claiming it is possible to do so while maintaining immor tality would be a bad thing. The idea that boredom will develop if there was no end to human life will be explored, assessing much of the support from Bernard Williams (1973) as well as opposing and tackling one of John Martin Fischers (1994) criticisms of the above view. The second argument that I will present (which overlaps with my first) will be based on the meaning of life, I will argue that death and the very limitations that it sets down gives life meaning and this will be explored by assessing the views of Victor Frankl (1957) as well as counterarguments by Robert Nozicks (1981). Firstly, to determine whether immortality is a good thing, I pose the question of whether death is a bad thing. Death is an ambiguous term so let me be clear of the definition it will take in my essay. I will take death to mean the end of the physical being, the cessation of life. I am aware that defining death in this way is problematic but let us assume for the sake of simplicity that this is correct. My concern at this point is whether death is a bad thing for the person who dies, referring to the state of non existence (at least in the physical form), not the process of dying. For many, a rational response in life is to fear death- after all, it is our most personal and valuable asset, but is it really, as Nagel stated, a terrible thing to go out of existence? There has been extensive philosophical discussion and disagreement regarding this matter, with philosophers such as Bernard Williams (1973), who argue death has its rightful place; a point to which I will later return, and there are those such as Thomas Nagel (1970) who speak of its badness. Lucretius, however, argue that something can only be good or bad for a person if that person exists at the time the event takes place and is experienced, if we take death to mean non-existence where non-existence is nothingness then death cannot be said to be good or bad as only something can be interpreted in this way. I, however, believe that death is bad, agreeing with Nagel in most parts but at the same time believe that immortality, never dying is also bad, this is not a contradiction. I disagree with the Lucretius argument for the very same reason Nagel rejected their reasoning, Nagel presents an example of an individual betrayed unknowingly behind his back, although the person never becomes aware of this, it seems fair to say that the betrayal was a bad thing for the person involved, in this way the Lucretius connection between badness and experience does not hold true (Nagel, 1970:76). It may be the case that something can be intrinsically bad, bad in itself or in its own right, for example, pain is avoided for its own sake. It may also be the case that something can be comparatively bad, bad by virtue of what youre not getting while this other thing is present. I take the latter point to be the case for the badness of death. It seems to me that something can be bad even if you dont exist, e xistence is not a requirement, in fact it is the very fact that you dont exist that makes death bad. The central bad about death, about non existence, is that it deprives you of the goods of life you might otherwise be getting, I couldnt fall in love, enjoy a sunset or master philosophy.From this, it should follow that life is good because if I wasnt dead I wouldnt be deprived; more of a good thing is always better than less of a good thing; therefore more life is better than less life; it should follow therefore that eternal life never dying is exceptionally good. However, the rules of logic and reason do not require somebody who accepts the deprivation account to believe that immortality is to be desired. Looking closely at the deprivation account, what it claims is that death is bad insofar as it deprives us of the good things we could have otherwise experienced, but we shouldnt assume that life is good or always good (maybe Nagel does or often seems to assume this) what if it turned out that what you would have hereafter would be in fact a life full of bad things. It would there fore be a bad thing that you would go through the rest of your life which in this case would be an eternity with negative experiences. I will now go on to explain that it is an inevitability that an eternal life will somewhere down the line cease to be good, transforming into an eternity of badness in which case still in accordance with the deprivation account death will no longer be bad. I agree that at first thought immortality may be tempting the argument that life is too short will no longer exist. Think of all the things you could get done, you could devout years to writing great philosophy, you could take pleasure in countless sunsets and sunrises, you could enjoy things endlessly having more time to see and achieve things that you would have otherwise not had time to. Here is my argument, too much of a good thing can become a bad thing, medicine for example is something which is instrumentally good, however, although it is good in small doses in that it cures a disease for example if I take more than the prescribed amount it becomes harmful to my body. In this same way extending human life by 50 or even a 100 years can be good but what if someone added a thousand, a million, an eternity to your life? Having done and seen everything you could possible have imagined everything will start to feel the same, having experienced love and the sunset millions of times t hey would no longer excite you. Eternity is a very long time, forever goes on forever and boredom will eventually set in leaving you existing as oppose to living. It seems that I am in agreement with Bernard Williams, in his essay â€Å"The Makropulos Case:Reflections on the Tedium of Immortality†(1973) who also argues that an eternal existence would be intolerable, claiming that as human beings it is inevitable that by our very nature we will get bored we would be doomed to never ending repetition and boredom, life would simply be devoid of interest or freshness. He supports his view by discussing a play by Karel Capek which tells of a woman named Elina Makropulos, who at the age of 42 was given an elixir of eternal life by her father. The play is set 300 years on and Elina is now aged 342, Williams states that â€Å"Her unending life has come to a state of boredom, indifference, and coldness. Everything is joyless: â€Å"in the end it is the same,†she says, â€Å"singing and silence.†She refuses to take the elixir again; she dies; and the formula is deliberately destroyed by a young woman among the protest of some older men†(Williams,1973:82). EM has lived her life at the age of 42 for 300 years and it seems that everything that could happen to a woman of 42 has already happened to her. John Martin Fischer in an article titled Why immortality is not so bad criticizes Williams argument; Fischer asserts that if there was a sufficiently diverse package of experiences we would not get bored (Fischer 1994). He acknowledges that there are those pleasures that would be self exhausting, those which we would not want to repeat more than once or a few times as we would inevitably get bored. His examples of these self exhausting pleasures include pleasures that are disappointing which one would not want to repeat for that very reason and those non-disappointing pleasures which you do to fulfil a goal to prove something to yourself, for example, to overcome your phobia of heights you climb Mount Whitney but this is an experience you do not want to repeat. He acknowledges that there are those pleasures that are self exhausting but ther e are many repeatable pleasures that we would never get bored of like listening to beautiful music or seeing great art and we would therefore never fall victim to Williams boredom account. I disagree with Fischer, firstly it seems to me his examples of self exhausting pleasures present a distorted view of what pleasure really is. I agree that disappointing pleasures may appear to be pleasurable before the act but after we experience the disappointment they cease to fall into this category. It appears that these disappointing pleasures are not pleasures at all and should not fall into the category of self exhausting pleasures. It is a similar case for his example of non disappointing self exhausting pleasures like climbing a mountain to overcome a phobia, climbing this mountain is not done for sheer pleasure, we may experience pride and we may experience some pleasure from this pride but the very act is done reluctantly and is not pleasurable within itself. To claim that he partly agrees with Williams that there are those pleasure that are self exhausting is somewhat misleading what he presents in the above case are not pleasures at all. What Williams said, is to think of the most perfect immortality that you can imagine and imagine doing this forever, the above so called pleasures do not fall into this; it seems obvious they would not want to be repeated. Fischer also goes on to explain a second category of pleasures which he called repeatable pleasures which include listening to music and enjoying art, Fischer believed that if these pleasures were appropriately distributed (not too closely to each other ) they could be repeated countless times. I disagree; although in this case they could be classed as pleasure, it seems we would still inevitably get bored maybe not after 100 or even two hundred years but somewhere down the line of a never ending life we would get bored. I can only enjoy a piece of music a limited number of times before it no longer brings me pleasure. However at this point an objection may arise; some may argue that human potential is endless reducing the likelihood of boredom. There are millions of songs to be heard and millions more that will emerge, there is a countless number of things that can be enjoyed that will never run out so you are not doomed to be repeating the same things over and over, and maybe when things start to get tedious new things will be invented to occupy our minds. The response to this is that having heard a thousand, a million, two million, songs they will all eventually take the same shape, nothing new can be invented that would be so drastically different from all previous inventions. Another point to be made is that Elina Makropulos maintains the same character throughout her life changing only to adapt to her surroundings it could therefore be suggested that the boredom she experienced was a result of her unchanging character not the fact that she lived for such a long period of time. Williams addresses this throughout his article, he argues that as human beings we aim to be, and usually succeed, in becoming a certain type of person, we develop a certain set of interests, a certain way of acting and we become settled as that type of person. His thought is that those who can avoid boredom and continue to find things interesting are not sufficiently mature there seems to be something wrong with them as such immortality is not a life for a hu man being (Williams 1973) . Let us now introduce a way boredom can be avoided in accordance with his argument, a possibility Williams considers is rejuvenation; by this he means you remain a human being in that you maintain the same body but every so often you are rejuvenated, a certain part of your history disappears and is replaced by a new start. Although this seems to deal with the boredom issue Williams does questions whether this is in fact you? Every time I am rejuvenated I have no recollection of my prior self and build a whole new character based on different memories and experiences. It seems wrong to say that I am the same person after being rejuvenated for the hundredth time as I was prior to my first rejuvenation (Williams,1973:92). Even if we are persuaded that you are the same person Williams would argue that it is not giving you anything that you could be interested in, the absence of a continuity of consciousness is a serious problem. Even if it is not death it is as bad as death to be rejuvenated in this way. Another possibility to consider is the gradual deterioration of memory where we forget things as time goes on for example every 200 years. However I believe this raises the same question as above are we really the same person if we live in a 200 year envelope? Williams concludes that death is a necessary e vil; we should hope to die if we are to avoid the alternative of immortality. My second argument to why immortality is not desirable is based on the meaning of life. I believe that death and the very limitations that it sets down gives life meaning. My second argument overlaps with my first but what I wish to specifically argue here is that it is the very fact that we are here for what is comparatively a short time that makes our lives meaningful, in the way we act and behave, this is the idea that it is time pressure that shapes our lives. It is irrelevant whether one believes or does not believe in god or any form of creator or greater being, they will still find life meaningless without death, even if you merely carry on living out of the fear of dying. I believe that all good things have to have a beginning, middle and an end and each is necessary and is enjoyed accordingly. Victor Frankl argues that death itself is what makes life meaningful, his reasoning is as follows: â€Å"What would our lives be like if they were not finite in time, but infinite? If we were immortal, we would legitimately postpone every action forever. It would be of no consequence whether or not we did a thing now; every act might just as well be done tomorrow or the day after or a year from now or ten years hence. But in the face of death as absolute finis to our future boundary to our possibilities, we are under the imperative of utilizing our lifetimes to utmost, not letting the singular opportunities- whose finite sum constitutes the whole of life-pass by unused†(Frankl,1957:73). Nozick , however, has a problem with this argument, in his book â€Å"Philosophical explanation†he wonders whether death in fact makes life meaningless not meaningful, he argues that â€Å"Frankl assumes our only desire is to have done certain things, to put certain things somewhere on our record†¦Ã¢â‚¬ ¦.However, we may desire to do things; our desire need not be merely to have done them. Moreover, if we had an infinite life, we might view it as a whole, as something to organize, shape and do something with†(Nozick,1981:579-580) I disagree, firstly it was not assumed by Frankl that we merely do things to put them on record, what was being said is that we have a limited amount of time to do things but we do not merely do them just to tick a box but to grow and evolve as human beings because pursuing our goals enriches our lives. It is the very fact that we have a finite time that motivates us to make those decisions and do those things that enhance our lives, which would only be forever delayed with an infinite existence. For example why should I go to school if I dont like it? The simple answer is to learn to acquire skills that would help me to achieve and make something of my self before I die and cease to exist. If I was immortal, learning trigonometry would seem less attractive than watching TV or playing computer games all day. I get more pleasure from such things (in the short term at least) and watching TV is certainly easier than studying and Ill get round to learning trigonometry sometime.Time press ure is what makes us set goals, with an immortal life tasks would forever be extended and a consequence would emerge whereby we would be less likely to do things of value, we would become a stagnant society where simple pleasures rule. Even if we are partly motivated by the desire to do things not only to have done things they would still be postponed and contrary to what Nozick claims this would matter as the desire alone to do things does not make ones life meaningful it may contribute to some poor will to carry on living (to do that specific thing) but will not give satisfaction to ones life. Nozick also questions whether death in fact makes life meaningless? Many argue that death renders life futile because we will all eventually die and so there is no point in developing character or studying calculus if our progress is ultimately going to be permanently interrupted and it will all go to waste. It seems to me that to argue that death makes life meaningless is to argue that something can only be meaningful if it lasts forever. The truth is that many things we value and find worthwhile do not last forever. I affirm that most if not all actions other than pleasures within themselves are predominantly motivated by the desire to get things done and enrich our lives from them before we die. Death is a deadline, a necessary evil; we know every day that passes we will never get back and this gives meaning and shapes how we live and thus an immortal life is not one to be desired. So far a strong argument has been provided for the undesirability of an immortal life but is there any situation in which immortality can be desired? In setting out what I meant by immortality I disallowed a get out clause, let us now suppose you would be able to live as long as you wanted and when you eventually had enough it would be possible to take your own life, is the elixir of eternal existence now more attractive? Surely it is, however, this is not all together straight forward. Take for example a mortal who chooses to commit suicide, in taking their own life he/she is giving up for example another 30 years, however, in the case of an immortal he/she is giving up what is essentially an eternity. They may be unhappy now but they could not possibly know that this would be the case in a million or a billion years time, choosing to take an immortal life is of greater consequence. In allowing a get out clause we would also become a very unadventurous and risk- averse society, who would take the risk of bungee jumping, paragliding and so forth if what they are risking is an infinite lifespan? Although this may seem a more attractive model of immortality it is complicated and can it really be called immortality if we allow this get out clause? It seems to me the very fact that we would choose this model supports my argument, that immortality would cease to be good and we would all sooner or later opt to take our own lives. In conclusion immortality in the physical human sense is never a good thing. It should not be desired; whatever perfect life you imagine to want to experience forever it will soon become tedious and boredom will eventually set in. Death is therefore necessary, even in accordance with the deprivation account, as further existence would become a bad thing sooner or later and it will no longer be the case whereby death deprives you of the good things life has to offer but where death provides an end to all that is bad with an eternal existence. It is also the inevitability of death that gives life reason and shape, the very fact that we have a limited lifespan motivates people through a sense of urgency to spend their time doing those things that contribute meaning and enrich their lives which would forever be delayed with inevitable consequences with an immortal life. Without death there would be no such thing as sacrifice, putting a lifes work into something, heroism and courage, we w ould lack appreciation for our existence, life would not be as serious or meaningful. I believe there to be an artistic necessity about dying- in the same way a picture has a frame, one cannot imagine an infinite painting, or a play has a shape and a final curtain, one cant imagine a play going on forever. Why grope for some mysterious realm for which we are not properly equipped to function in? Although I have argued that immortality is bad, this is not to say that it is a good thing that we die when we do, in accordance with all above arguments one can still think that we die too soon.

Adult versus children learning
Although it is my opinion that children and adults differ in the degree to which methods facilitate their learning, I still think that both have the ability to profit from the use of those similar methods. Such strategies as rehearsal and repetition seem to work especially well with children, though less so with adults. I believe this has to do with the fact that children naturally find repetition a diverting exercise, while adults generally dislike doing it. Motivation, therefore, plays a major role in the success of both learners. Such methods of learning as metaphors and imagery would appear to have similar effects on both adults and children. It would seem to me that these methods would work better with adults, who are likely to already possess a schema for much of what is being learned and would thereby be able to make better connections. However, I once read of such learning inhibitors as interference (especially in adult language learning), in which prior knowledge of a language and expectations about learning get in the way of the information to be assimilated (August, 2006). Motivation is also a critical aspect of learning (Zhao & Mogan, 2004). Adults tend to be more motivated when learning, and therefore, in such cases will be able to benefit from methods that might otherwise not be conducive to adult learning. I think the efficacy of such methods as repetition is dependent on the person’s willingness to do it. A motivated adult would therefore benefit from repetition as a learning method. For example, a few summers ago I tried to learn German, and even though I stopped after a few months, I find that the motivation I had at the time caused me to learn quite a few vocabulary words via repetition. This is the same method I used as a child while learning Spanish in high school. As an adult, my motivation was to communicate with a Swiss friend whom I was tutoring; as a child, it was to continue getting some of the highest Spanish grades in my class. Both experiences suggest to me that children and adults tend to learn in similar ways. References August, G.

Organic Lab 7
Amanda Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary, secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric acid.The reaction occurs through a nucleophilic substitution, which is when a nucleophile replaces the leaving group in the substrate. In this lab, the hydroxyl group of t-butyl alcohol is replaced by a chlorine atom. The reaction proceeds through an SN1 mechanism (Weldegirma 38-41). â€Å"A nucleophile is any neutral or uncharged molecule with an unshared pair of electrons. In the substitution reaction, the nucleophile donates an electron pair to the substrate, leading to the formation of a n ew bond to the nucleophile, while breaking the existing bond to the leaving group†(Solomons and Fryhle 99-102).The two types of nucleophilic substitution reactions, SN1 and SN2, are identified based on whether the different steps occur simultaneously (SN1) or in two separate steps (SN2). To synthesize the t-butyl chloride, the t-butyl alcohol goes through an SN1 reaction. Also, the nature of the solvent can affect which substitution reaction will occur. Polar protic solvents typically favor SN1 reactions. This is because the SN1 mechanism is carried out in two steps and the polar protic solvent produces both a cation and an anion which are capable of stabilizing the charges on the ions formed during the reaction.Because an SN2 reaction occurs in one step, this is unfavorable; however, the SN2 reactions tend to favor polar aprotic solvents. Another factor affecting the type of substitution reaction is the nature of the leaving group. Since the SN1 reactions occur in one step, they generally require an excellent leaving group and won’t typically run with a poor leaving group. The SN2 reaction also favors excellent leaving groups but can run with any type of leaving group because it is run in two different steps. To synthesize the t-butyl chloride, the t-butyl alcohol goes through an SN1 reaction. Weldegirma 38-41).

In order to test if we properly received our product we tested the sample with two different solvents, a solvent of sodium iodide and silver nitrate. If an alkyl halide is a tertiary one, it can easily react with a solvent of silver nitrate to generate a relatively stable tertiary carbocation through an SN1 reaction.If an alkyl halide is a primary one, it can then react with iodide ions in the sodium iodide solvent by an SN2 mechanism showing a precipitate of insoluble sodium chloride. Heat can also be used in this process to speed up the reaction (Weldegirma 38-41). The first test we ran was t-butyl chloride and sodium iodine. After mixing the two compounds , there was only a slight tint to the liquid but remained clear and precipitate free for 6 minutes of being room temperature. We then placed it in a warm water in which there was no precipitate that formed while being heated.This test yielded a negative result. The second test that we ran was t-butyl chloride and silver nitrate. Directly after mixing the compounds, there was an immediate white precipitate that had formed. This test yielded a positive result. A negative result with sodium iodide and a positive result of silver nitrate concluded that our solution of t-butyl chloride was a pure tertiary alkyl halide. Our third test was run with t-chloro butane and sodium iodide. This test initially did not form a precipitate while it was kept at room temperature.We then used a warm water bath in which after 5 minutes the solution formed a white precipitate and a yellow liquid. This shows that this test was a positive test. The fourth test was with t-chloro butane and silver nitrate. Th is test did not form a precipitate at room temperature or during the steam bath. This shows a negative result. With the t-chloro butane, the negative result with silver nitrate and the positive result of sodium iodide prove that this is indeed a primary alkyl halide. Conclusion:In this lab, we properly carried out an SN1 reaction from t-butyl alcohol to t-butyl chloride and found that we did in fact create a t-butyl chloride by getting a positive result from our silver nitrate test in the end. Although we weren’t able to visibly see with our eye the nucleophilic attack, the steps that we carried out in the lab showed the separated layers and that there were reactions going on during each step. The organic layer that was continuously washed was undergoing the slow reaction process during each separating stage.In the end, after the distillation of the solution, the SN1 reaction was completely carried out. The information from this data has revealed that it is possible to carry out an SN1 reaction in a lab; however, in the process of washing the product there will be a lot of material lost giving a low percent yield in the end. It would be smart to use chemicals that are inexpensive and in large quantities to carry out these types of reactions. The information and techniques performed in this lab could be applied to other situations in an industrial setting.One example of this could be creating chlorofluorocarbons which used to be produced for aerosol cans and other products. Although these are no longer widely used in the world due to ozone effect, the SN1 reaction could be done with these chemicals. Overall, the lab accomplished what it was set out to do.
