War on terrorism - Essay Example Morgan speaks about Canadian politicians in the following terms: "they've been using that familiar demon -the United States and all its evils- as the fuel to heat Canadian voters to a frenzy. () And all the while, they're studiously ignoring Canada's own homegrown issues." Morgan stated the following about Canadians in general: "There's no denying that Canadians are in an even more anti-American mood than usual, thanks to the Iraq war and the Bush administration's perceived arrogance. () Politicians here know that Canadians love to read, talk and debate about U. S. transgressions. Newspaper articles point to ethnic profiling at airports and long border waits as evidence that the war on terrorism is a sham, and that Americans are simply looking for excuses to harass Canadians for the country's multicultural society." (Morgan, 2006). Morgan pointed out the following about Canada's Prime Minister Paul Martin, the NAFTA's accord, and the Canadian government: "he (Martin) conveniently neglected to mention that Canada, which is one of the accord's major promoters, so far hasn't complied with its emission reduction requirements.

Quantitve and qualitative method of research, sociology Essay

Quantitve and qualitative method of research, sociology - Essay Example Research methodology is the procedural framework within which the research is conducted. The methodology would depend upon the topic to be researched and the specific research questions are the primary drivers. Positivism (quantitative with hypothesis testing) and interpretivism (qualitative with hypothesis generalizations) are the different types of research philosophies, each has its own purposes and advantages. Research philosophy highlights two different schools of thought on the how to conduct research. Arguments should be evaluated in different ways because primarily arguments have different roles and purposes and people assess according to the purpose in their mind. At times arguments provide useful information depending on one’s knowledge of how the world works. In a different setting, one can take an abstract approach and ask what follows from a given set of information and then decide on the outcome. Arguments can be evaluated in two qualitatively different ways – in terms of their deductive correctness or in terms of inductive strength (Rips, 2001). Quantitative methodology is a positivist approach in sociology research. Positivism is characterized by operational definitions, objectivity, replicability and causality (Bryman, 1984). Through questionnaire items the concepts can be operationalized; objectivity can be obtained by maintaining distance between the observer and the observed. By applying the same research instrument in another context replication can be maintained and causality is handled through path analysis and related regression techniques. Quantitative investigations look for â€Å"distinguishing characteristics, elemental properties and empirical boundaries’ and tend to measure â€Å"how much† or â€Å"how often† (Nau, 1995 cited by Amaratunga et al.,). Quantitative research designs determine the truth value of propositions and allow flexibility in the

Making reference to Language and imagery Essay The play of Macbeth is based around a soldier who went by the name of Macbeth Ambition got the better of Macbeth and drove him to work his way up the hierarchy by whatever means he thought was necessary. Of course he did meet some obstacles on the way, but instead of hurdling over them he got rid of them. Eliminating these obstacles is what caused Macbeths transition from a brave Macbeth to abhorred heir by the end of the play. However its not a clear cut answer. There were many contributing factors. It wasnt simply all Macbeths doing that got him where he was at the end of the play. Many characters played a role in his downfall. At the start of the play we do not meet Macbeth but we are told about him, For brave Macbeth, well he deserves that name, here is where a soldier is speaking to King Duncan and telling him that Macbeth does deserve to be called brave. This is where we first hear of Macbeth before we actually meet him. The next thing that the soldier tells Duncan is a small piece of description of why Macbeth should be called brave, Disdaining fortune, with his brandishd steel, Which smokd with bloody execution, Here Shakespeare uses certain dramatic words to create an image of what Macbeth was like. The way the soldier tells Duncan that Macbeths steel was covered with bloody execution, which gives us an image of a man covered in blood from the people he has executed. When Macbeth meets the three witches for the first time he is immediately interested in what they have to say and he does ask them to speak if they can. Macbeths immediate reaction to what the witches had said was interesting, he wanted to know more as he was confused by the prophesy of him becoming King, Speak, I charge you here Macbeth tries to order the witches to say more but they vanish. The witches were very smart; they told Macbeth the hard facts but they didnt tell him how or when he would be King or Thane Cawdor. This leaves him hanging. Macbeth and Banquo are, as expected, shocked. The witches here could have simply be spinning a line of lies and see if Macbeth would grab it as he did and the witches now know that Macbeth must be pretty easily convinced as he was when he heard the prophesies. Macbeth and Banquo, when the witches are gone, then think if what they had seen and heard was actually there or were they going mad, where such things here as we do speak about? Or have we eaten on the insane root. That takes the reason prisoner? Here Banquo asks Macbeth if what they are talking about was actually there or have they eaten on the insane root and just gone mad. So even when they have heard the prophecy it shows you how shocked they are if they are questioning their own sanity. Macbeth may take the bait from the witches but Banquo tries to worn Macbeth that there must be evil forces at work and that it may seem in his favour now but there is something sinister in the predictions, What, can the devil speak true? Banquo here tries to convince Macbeth that can these witches related to the devil speak truth and so he tries to over throw Macbeths thoughts to forget about the prophesies and just to carry on as normal. The first seed of ambition that is thrown to Macbeth came from the witches prophecy of Macbeth becoming King. However the seed did not start to grow until Macbeth hears that he is going to become the new Thane of Cawdor this being the first prophecy made by the witches come true. At this point Macbeth and Banquo had decided to let the future take care of itself. However when he was told that he would be the new Thane of Cawdor a bell started to ring in his head. Soon after this, Duncan makes his son Malcolm the Prince of Cumberland and Duncan invites himself to Macbeths Castle. Everything is falling into place for Macbeth and he sees his chance to become King; obviously Duncan was not planning on making Macbeth the next King. However Macbeth then had a problem and that was Malcolm, The Prince of Cumberland _ that is a step, On which I must fall down, or else oerleep, For in my way it lies. This is where Macbeth realises that he has a hurdle to overleap in order to for fulfil his ambition to become King of Scotland. This is where Shakespeare tries to explain Macbeths situation in a simple way by creating an image of a staircase, Malcolm on the step above him and the King Duncan above that. This is where he has a choice of whether to get rid of Malcolm or some how get him out of the way so that he could fall into the place or step that he was on and then he would be another step closer to becoming the King. Duncan appears to continuously present Macbeth with gifts and titles. This fuels Macbeths ambition and makes him yearn for more authority, such as to be the King of Scotland. Presenting Macbeth with gifts and titles led to Macbeths transition or you could say his tragedy, but Duncan cannot be entirely to blame because he was simply rewarding Macbeth for his triumphs and bravery on the battlefield over much larger armies, What he hath lost noble Macbeth hath won. Here we get a great feeling that Macbeth is a very strong and powerful soldier on the battlefield. Here it says that what other soldiers have lost, such as a battle or war, Macbeth will definitely win. Lady Macbeth latches on to the idea of Macbeth being King as soon as she reads his letter describing the prophesy. She has no doubt that the prophecy will come true, but she does fear that her husband is, to full o the milk of human kindness to catch the nearest way. Lady Macbeth immediately sees that killing Duncan is necessary for Macbeth to become King, and she has no concern for how evil that plan is. As soon as she sees him, she begins convincing him that he should kill the King. Macbeth does not agree, but later in scene seven, he tells Lady Macbeth: We will proceed no further in this business. She responds by attacking his manhood, calling him a coward and referring to a promise she never made. I would while it was smiling in my face Have plucked my nipple from his boneless gums, And dash the brains out, had I so sworn as you Have you done to this. Macbeth never made a promise to kill Duncan but Lady Macbeth is trying to manipulate him by saying if she had made a promise to kill her child she would, Macbeth has sworn to kill Duncan but she is simply playing with his mind and trying to get him to go along with the murder. Later on in scene seven Macbeth tells his wife that he doesnt want to take the positions away from the soldiers or Thanes because they have earned their position and clothes that hey wear, he just wanted to become King the easiest and quickest way. Lady Macbeth tries to explain to her husband that there will be an obstacle or downside along the way, Letting I dare not wait upon I would, Like the poor cat i th adage? Lady Macbeth here tries to be persuasive by telling Macbeth that she would not let fear get the better of her as he was starting to do. She then uses the proverb an adage to try and explain that obstacles often occur when someone really wants something and puts his situation into a way that he could relate to. Lady Macbeth said to Macbeth the cat wanted the fish but would not get her paws wet, translating into Macbeths case, he wanted to become King but didnt want to kill for it. After the murder of Duncan Lady Macbeth has to assure Macbeth that what is done is done and not to think about it as it will drive him insane. Macbeth was still shaken after the murder and took the daggers, that he killed the guards with, back with him. Lady Macbeth then had to take charge, Infirm of purpose! Give me the daggers. Lady Macbeth even after the murder is still insulting her husband and calls him weak minded. Lady Macbeth plays an important role in Macbeths transition. Lady Macbeth is like her husbands bad conscience, there were many points in the play where Macbeth would have pulled out from murdering Duncan but his wife tried her best and seceded in convincing Macbeth that he should murder Duncan. However I do not think that she can be held entirely to blame; Macbeth had free will to do what he wanted; Lady Macbeth simply backed him up. Therefore it was through Macbeths decisions he became the man he was at the end of the play. You could say that he was some what forced into murdering Banquo. It is concluded! Banquo, thy souls flight, If it find heaven, must find it tonight. Here Macbeth has plotted the death of Banquo, and is pleased that his friend would soon be dead. He does all this without any prompting at all from Lady Macbeth; he does this simply because the witches had said that Banquos descendants would be Kings. Macbeth furthers his own transition by having Macduffs family killed. The castle of Macduff I will surprise, Seize upon Fife, give to the edge o the sword His wife, his babes, and all unfortunate sould That trace him in his line. Straight after the second prophesy, which warns him to beware the Thane of Fife, that being Macduff. Lennox brings word that Macduff has fled to England. Angered, and the words from the prophesy that he has interpreted to mean that Macduff may be a threat, Macbeth orders the household of Macduff slaughtered. When Macduff had found this out he was truly convinced that Macbeth is evil, and rallied the armies of proud England to march against the sick Scotland. Therefore, by destroying the Macduff household, Macbeth brung about his own downfall or transition by the end of the play. Prior to this Macbeth once again made another step towards his own transition. He yearned for the knowledge that the witches possessed and he couldnt do anything without knowing what was going to happen in the future. The second time Macbeth went to visit the witches they had three new prophecies for him, The power of man, for none of woman born Shall harm Macbeth This first prophesy is simply saying that the person born not of a woman shall harm Macbeth. Macbeth thinks that this is impossible, what he doesnt realise is that Macduff was born by a suzerain Macbeth shall never vanquishd be until Great Birnam Wood to high Dunsinane Hill Shall come against him. Here the witches say that only harm will come to Macbeth when Birnam Wood comes to Dunsinane, which Macbeth thinks is impossible. The other prophesy was, Beware Macduff, Beware the Thane of Fife. Here the witches are simply telling Macbeth to beware Macduff. As he believed all the prophesies he made them come true, so we dont actually know whether they simply fed him a line and influenced his thinking knowing that he was ambitious and would make these prophesies come true. This is yet another factor in Macbeths downfall. Macbeth surprisingly actually tries to comfort himself and in a way he tries to justify what he has done, I am in blood stepped in so far that returning were as tedious as go oer. Macbeth here is trying to say that going back from what he had done would be as tedious as it was committing the murder, he seems to think that because he is so far stepped in blood and cannot turn back that it makes everything alright which it certainly doesnt. Even though Macbeth sees Banquos ghost he doesnt seem to show any remorse. However the ghost does startled him and he doesnt feel like a man when the ghost is there, Enter GHOST, And to our dear friend Banquo whom we miss; Would he were here. To all, and him we thirst And all to all. Banquos ghost enters the banquet and Macbeth decides to propose a toast to Banquo, its as if Macbeth is tying taunt Banquos ghost, Macbeth is not really sorry and he wouldnt rather Banquo be there he is simply boasting to the ghost that he had him killed. However at the point when the armies of England are closing in on Dunsinane, where Macbeths castle is, Macbeth seems remorseful. It seems that his darker side was turning towards the light, but still, Macbeth refused to let anyone or anything threat his reign, except his death. But get thee back my soul is too much charged With the blood of thine already. Shakespeare uses imagery here to show how Macbeths soul is fully charged like a battery but with all the bad deeds he had committed. This part of the play is where Macbeth is confronted by Macduff and he is remorseful that he has killed Macduffs household. But nevertheless the deed was done and Macbeth could only blame himself for it. In conclusion I think that Macbeth was more so to blame for his own transition. He may have been pushed into the murdering of Duncan but everything else he made his own mind up about. Sure there where many limiting factors in Macbeths transition such as Lady Macbeth, the witches and another big factor being his ambition which was probably reflecting his decision making but this cannot be excused as he knew exactly what he was doing and what his aim was, to become the King of Scotland. However he does show some remorse before he is killed. Before Macbeth was killed Macduff started to fight with him but Macbeth could fight no more and so Macbeth was beheaded. This does show that he may have finally realised what he had done or that he was blinded from the truth by his ambitions.

Ethical Issues In Contractors Tendering Practices Construction Essay

Ethical Issues In Contractors Tendering Practices Construction Essay Ethics examine the morality of human conduct; it studies the basic principles of moral behaviour and is concern with the right or wrong of human behaviour. Every rational human being has an idea of what it is for something to be right or wrong, although sometimes it is difficult to evaluate what is wrong or right depending on the circumstance of such action (Etim, 1999). Business ethics is therefore a collection of moral principles or a set of values dealing with what is right or wrong, good or bad in business transactions. Such sets of values are being shared within the business community as well as the society as a whole. Moral ideas are considered to be inappropriate for everyday business dealings and some actions are disregarded due to the strong desire to make profit. Some have argued that ethics and business do not mix, and that the two are in direct conflict with each other. In fact, it has been said that companies that are truly ethical are going out of existence. Construction contracts can be obtained by negotiation or by competitive tendering (Shash, 1993; Ashworth, 2001). In competitive tendering, an owner invites a selected number of contractors to compete for the project. This method of tendering is considered as the most common means by which building and engineering contracting firms obtain works, and the dominant mechanism for allocating construction contracts (Ward, 1979; Yusif and Odeyinka, 2000; Ashworth, 2001; Hiyassat, 2001; Harris and McCaffer, 2001; Shen et al, 2004). The business of tendering for construction contracts has a large ethical component. Ethical principles in tendering are formally prescribed in the codes of conduct related to tendering process. The codes are designed to delegate responsibilities to both competing contractors and the client and to minimize the potentials for unethical practices. This work intends to examine cover pricing, collusive tendering and rate loading among other unethical practices which construction contractors sometimes engage in during tendering. Cover pricing in construction tendering Fu, Drew and Lo (2004) observe that contractors tendering behaviour is subject to their winning intent. It is however known that winning may not be the only objective in tendering. Although the tendering codes stipulates that tenderers shall only bid where they intend to carry out the work if successful, some contractors for some reasons sometime decide to submit tenders based on cover-price. Cover prices are tender prices which have been provided at rates specifically designed to lose the tender but which may appear to be competitive. Despite attempts to prevent this practice, several instances of cover pricing sometimes called non-serious tenders have been reported. When a contractor with a reasonable workload receives a set of tender documents from a reputable client and consulting organizations, the contractor has to decide what to do: first whether to do nothing, to return the tender documents or to submit a tender. A tender may be submitted in one of three ways: by obtaining a cover price, by preparing a tender based on accurate estimate, and by preparing a tender based on approximate estimate. The option to do nothing is not considered suitable due to the potential harm such a course of action might cause to the reputation of the contractor with the client, consultants and their business contacts. Also the option of returning the tender documents may be perceived by the contractor as unsatisfactory because it might mean exclusion from future tender list, although this should not be the case according to the code of procedure for tendering. Some reasons for the issuing of cover price by contractors to include: little interest in the contract; lack of resources to competently complete the work; shortage of time to compile tender; desire to remain considered for future contracts; and little chance of winning due to the large number competing contractors for the same contract. It is reported in Skitmore and Runeson (1999) that clients often give the perception that a failure to tender will prejudice a contracting firm in the future tendering exercise, and the consequence of this is the so called cover price which cannot easily be distinguished from a genuine competitive tender. Also, Runeson (1988) remarks that some tenders are based on cover prices not intended to win the contract and therefore above the expected price, and submitted to recover deposit moneys or to keep faith with the client or consultants. However, Lowe and Parvar (2004) provide a different perspective to cover pricing. They submit that tendering options available to a contractor are simply acceptance or rejection of the tendering opportunity, although, rejection does not mean that the contractor does not submit a tender. Unsatisfactory past experience with a particular client or consultants regarding personality or payment, high cost of tendering and inadequate information often resulted in inflation of the tender price (cover price) rather than a refusal to tender. Cover price can ruin the competitiveness of a tendering process and can also lead to collusion among tendering contractors. However, despite its unethical nature and illegality in some countries, there are some arguments in its favour. The shortage of time to compile a bona fide tender could compel a contractor to submit tenders based on cover price. The recognition of this fact may have prompted the Nigerian Institute of Quantity Surveyors (NIQS) in its Code of Procedure for Competitive Tender to state that: time allowed for completion of tender should relate to the scope of project. Adequate tendering time allows tenderers to obtain competitive quotations and thus, ensure the return of most competitive prices with least mistakes (Clause 4.2.1) Lowe and Parvar (2004) believe that only few contractors will actually decline an invitation to tender. However, it appears that contractors react differently to the perceived fear that the option of returning tender documents might exclude them from clientsà ¢Ã¢â€š ¬Ã¢â€ž ¢ future tender process The report of a survey of some Nigerian building contractors indicate that when they receive a set of tender documents at a time their firms have a reasonable workload, they return the tender documents to the clients or their representatives with an apology for their firmsà ¢Ã¢â€š ¬Ã¢â€ž ¢ inability to tender. Only a few contractors admit to engaging in the practice of cover pricing. Contractors who admit to using cover pricing in tendering reveal that their action is mostly driven by little or no interest in the contract under consideration and the desire to remain considered for future contracts and tendering process. Some contractors cited other reasons such as the personality of the cl ient, risk and unpredictability of the construction period as well as heavy workload as some reasons why cover pricing may be an option for their firms. Whether or not a cover price is provided with good intention, the fact remains that it results in lessening real competition of tenders. Collusion in Tendering Chen et al (2005) submit that one purpose of the standard tendering procedures is to reduce potential for collusion and manipulation of pricing. According to Ray et al (1999), collusion is a method of pricing control by contractors to substantially lessen competition. Collusive tendering occurs where several contractors have been invited to tender and the contractors agree among themselves either not to tender, or to tender in such a manner as not to be competitive with the other contractors. It has the effect of substantially lessening competition. The main reasons for this practice among contractors are that it provides: an even distribution of construction work for all the contractors involved a means of entering what is an apparently bona fide tender a means for discussion and agreement over illicit profit making such as amounts for cover price, and unsuccessful tendering fee. The practice, or possibilities for the practice of collusion is a factor among several other issues related to ethical tendering, and it is contrary to the ideals of competition. It only benefits those parties to the agreement at the expense of those outside, including clients and other contractors. Sheldon cited in Ray et al (1999), while examining collusion in the UK, holds that collusion agreement are seen as an attractive means of maintaining a steady flow of work and achieving higher, risk-adjusted, discounted profit. The tender codes of some countries clearly prohibit unethical practices such as collusion on tenders, inflation of prices to compensate unsuccessful tenderers or any such secret arrangements. The very fact that tendering contractors communicate with each other can be taken to be a form of collusive behaviour under competitive tendering process. Though, little evidence of collusive tendering seems to be available in Nigeria construction industry, it is pertinent for industry practitioners and clients to be aware of the possibility of such unethical practice. Rate loading Usually, a construction tender is priced in such a way that the prices of each item comprise the cost of that item plus a uniform percentage allowed as profit and overheads. This is not always the case. Contractors may mark up the bill items by different percentages to create some element of rate-loading in order to create a favourable cash flow. Two aspects of rate loading are front-end loading and claims loading. Construction contracts only become self-financing towards the completion of the project. Therefore contractors are required to engage a considerable amount of their own capital in the execution of the work, at least in the early stage. In an attempt to minimize the involvement of their capital and make the project self-financing at an early stage, they resort to price manipulations. Items which the contractor expects to be executed early in the project have prices which contain a disproportionately large content of overheads and profits and items to be executed in the later stage of the project have their prices reduced accordingly to maintain competitiveness (Fellows et al, 2002). This pricing strategy in construction tenders is referred to as front-end loading. Due to the time-value of money, the situation further benefit contractors but place a cash flow burden and greater risk on clients. There is also the practice of claims loading where contractors insert higher profit margin into unit rates related to those work items which they expect to be increased through variation orders during the execution of the contract (Xu and Tiong, 2002). Conclusion Unethical tendering practices such as cover pricing, collusive tendering and rate loading have the potential of reducing real competition and eroding the benefits of competitive tendering. They can also place enormous financial burden on client. Construction consultants therefore have a duty to carefully examine tenders for construction contracts to identify any such practice and possibly caution or sanction contractors who may have engage in these practices.

Romantic :: essays research papers

When you hear the term "Romanticism", wouldn’t you think of something that has to do with romance? That is what I thought when I first heard the word, but I was foolishly mistaken. Romanticism dealt with placing central importance upon the emotions and upon the individual. This time period only lasted about thirty years but greatly changed the and influenced the country in which we live in today. In the following composition, I will discuss the ideas of Romanticism and three famous writers of this time and their distinct subjects.The United States condensed as a nation during the major cultural change distinguished by the shift from classicism to Romanticism. This change had an impact on every aspect of culture including arts, philosophy, education and science.Before all this even happened, an earlier belief known as "Classicism" was around. This unhealthy culture put reason as their dominating characteristic of nature and were also bound by strict unchang ing laws by the government. Now, who would want to live under this dull inexpressible culture? Well, the early Puritans were part of this "Age of Reason" and many a good man came out of this era. Anyway, it was time for change. People wanted to start believing in themselves more and having a greater sense or nationalism. This is where Romanticism came in and replaced classicism. It was the beginning of a new era and initiated a whole new way of thinking. Romanticism basically dealt with three attitudes: Nature, the past, and the inner world of human nature. Although the early Romantic writers varied widely in the forms that they chose, these certain subjects were characteristics or Romantic attitudes.The writer who mainly told about nature was William Cullen Bryant. He became the first national spokesperson for a new religion of nature in which nature serves as a source of moral and spiritual lessons.One of his famous poems, "To a Waterfowl", tells of the journey of a waterfowl during migration and relates that to the path in which we as humans take in our lives. He also incorporates some religious attitudes in his works as well and you can see this at the end of "To a Waterfowl" when he tells you that "God will lead your steps aright" Washington Irving was a fine example of telling about the past. He wrote many a folk tales.In the short story "The Devil and Tom Walker" he Americanizes the devil and gives him qualities that are carried on with him for generations.

Source L is an account of the memories that Barbara Walsh had whilst being evacuated. The source is useful as it highlights the differences in social class and wealth, â€Å"The bathroom had a heated towel rail which I had never seen before†. This shows us that people had a different standard of living. People also had certain expectations, † astonished that London children could eat with knives and forks as they expected us to eat with our fingers.† Her experience tells us a lot about the feelings that evacuees could have, although hers are individual to her, â€Å"I can still remember the desolate feeling I had as, one by one, the friends with whom I had made the journey disappeared with their new ‘families’.† Her own feelings, opinions and experience may be similar to the majority of evacuees. Despite being written fifty years after the event the account still holds some very detailed factual information, â€Å"My sister and I were to share the guest room, which had single beds with blue sheets and blankets.† Also through the account we learn a lot about the process of evacuation, â€Å"I carried a small bag containing a change of clothes and washing kit, also my gasmask in a brown cardboard box. Her account also highlights differences in religion â€Å"As a zealous Catholic of seven years of age I felt indignant about this state of affairs and wrote â€Å"this should be a Catholic church† in the visitor’s book in red crayon and signed my name.† People of different religions were thrown together and expected to deal with the circumstances, Jews lived with staunch Catholics etc. this was due to cause many problems. However the source is written fifty years later and some details have been forgotten, like which station the children left from. The details that the author has included are the types of things a child would remember. Due to the fact that it has been so long Barbara Walsh’s memories may have been altered, either through her own wish to view it more positively or through the influence of media publishing popular images that may have been incorporated into her own. The account also has very little factual information and is solely the memories of the author and does not accommodate the experiences of anyone else. On the basis of this I think that although the source may be reliable, despite being written fifty years later, it is not particularly useful by itself. I think that the source is reliable because it does contain a lot of detailed information. I do not, however think that it is useful because it only gives us the feelings and experiences of one person. If it were to be used as part of a few sources with other people’s experiences then it may show us something different. Both sources H and I are photographs of homes destroyed after an air raid. They show us the loss of property and lives that place during air raids. It highlights the danger faced by the ordinary civilians each night. Source J is a table giving statistical information to how many bombs were dropped and damage to life and property in a given area. From this table we can see that Hammersmith and Fulham were not that badly affected, especially on comparison to places like Poplar. Source K is a letter from an unknown resident written during 1940, it reveals the names of roads, which were bombed and names some friends caught up. It also expresses the feelings of the author. Sources H and I have limited use, as they do not give us any factual details like those in source J, although they are clear visual resources. We do not know the origin of source J and so can not be sure that the information is correct, it also doesn’t give us any emotional details to see how the public were feeling like source K does. If all the information in Source K were true then it would be the most useful of the sources. However due to gossip and misinformation the source maybe unreliable. This source pinpoints exactly where the bombs landed and what was destroyed as well as giving us an insight into the feelings of the author, we must also remember that not all people will feel the same.
