Troubleshooting electric circuits - Essay Example As part of the pre-qualifying parameters, it is significant to identify the defected system, whether it is electrical or mechanical. This should be followed by a thorough analysis of the fault found in the identified system. Carrying out the troubleshooting steps would then follow for repairs. These techniques would make the troubleshooting a lot faster. In the scope of troubleshooting an electrical circuit, it is likewise of utmost importance to identify the controls and loads, clearly understand the sequence of the operation in a system, and the mastery of the basic circuit theory which will help in the analysis of the individual components at hand. To make the troubleshooting more systematic, I should look at the problem from a smaller view to a larger view which will project the picture as a whole. To carry the troubleshooting process effectively, I would extensively utilize the three important measuring devices: ohmmeter, voltmeter and ammeter. Nevertheless, these would not be e nough without having a view of the backbone of the system. This can be addressed by using schematic diagrams, electrical wiring diagram (EWD) and test lights. What should I do if the problem remains undetected after exhausting all the troubleshooting process? The answer depends on you

Howard Gardner Research Paper Example | Topics and Well Written Essays - 750 words

Howard Gardner - Research Paper Example As a result of further research Gardener and his colleagues have stated that there could be an addition of another 3 possible intelligences to the initial list of seven (Smith, 2002, 2008). The presence of one kind of intelligence is determined from several perspectives or criteria which were drawn from several fields such as biology, logical reasoning and various psychological factors. With this he concluded that every child whether normal, mentally or physically challenged will have their unique set of intelligences in which they will shine and both teachers and parents will have to employ a broad range of learning methods in order to identify the strengths and weaknesses of a child. Thus with his research on multiple intelligences Gardener sought to bring about a change in the system of learning with focus on the inherent abilities and interest of a child so that they will be able to pursue their interests and not succumb to external factors such as peer pressure (What are Multipl e Intelligences? n.d). ... e candidate intelligences in an individual include: the potential for brain isolation by brain damage, presence of an evolutionary history or possibility, a set of identifiable core operations, susceptibility to encoding, distinct developmental progression in which there is a defined end-state performance, the existence of idiot-savants, prodigies and other such unique individual, and aided with suitable support from psychological experiments and other psychometric findings (Gilman, 2001; Smith, 2002, 2008). The seven intelligences initially included in the MI theory are linguistic, logical-mathematical, musical, bodily-kinesthetic, spatial, interpersonal and intrapersonal. Of the seven the first two intelligences namely linguistic and logical have been used in the school curriculum to assess the language and reasoning skills of the students. The linguistic intelligence is the ability to read, write and effectively communicate in a language. Through this an individual should be able to express themselves and accomplish their set goals. The logical-mathematical reasoning is the ability to reason and analyze scientific issues and mathematical problems. The next three intelligences are associated with performing arts as they involve a coordination of the mind and the body. The musical intelligence includes performance, composition or listening skills in music. Understanding the musical pattern will enable an individual to compose pitches, rhythms and tones. Bodily-kinesthetic intelligence involves the effective use of bodily parts to perform an action. For example athletes, dancers and medical surgeons and craftsman have a high capacity for this intelligence. According to Gardener, this intelligence includes both the mind and the physical body as activities are performed

Death And Paralysis In The Sisters

Death And Paralysis In The Sisters In order to recognize that Joyces Dubliners is a work unified by death, it is necessary for one to return to the beginning, where a meticulous reading is paramount, and start again. The opening story, The Sisters, is concerned with death and its impact upon the living individuals left in its wake. If the reader considers its function as essentially an introductory chapter, one will start to detect a palpable semblance of unity throughout Dubliners, as this story establishes the overarching theme of death and its associated motifs: paralysis, silences, and epiphanies-the latter of which are inextricably rooted in the poetics of modernity. The Sisters is a story that is concerned with youth, which represents the beginning of a progression from childhood to maturity. In this regard, the storys form parallels the narrative for the reader, as the story at its heart is concerned with the young narrators developing awareness; at the same time, the reader starts to acquire a simultaneous awa reness of the afore-mentioned themes and motifs. As we shall see, The Sisters functions as a gnomon for the entire collection of stories, as its narrator is but one of many more who are stifled and subjugated by their environment-like a patient etherized upon a table, as the ubiquitous J. Alfred Prufrock might say (Eliott 1). The Sisters ushers the readers into the world of Dubliners through the eyes of a child narrator. The narrator, along with the reader, confronts images of death in the opening paragraph through a lighted square of window-analogous to the window-panes of J. Alfred Prufrock. It is here, at the very beginning, that the narrator introduces the word paralysis, heralding a theme which reoccurs with death throughout the entirety of Dubliners. In A Beginning: Signification, Story, and Discourse in Joyces The Sisters, Staley emphasizes the beginning paragraph as an overture for the themes, conflicts, and tensions that were to be evoked again and again à ¢Ã¢â€š ¬Ã‚ ¦ throughout all of Dubliners (20). Furthermore, Staley affirms that the initial sentences tone of finality and certainty à ¢Ã¢â€š ¬Ã‚ ¦ begins the circle of death for Dubliners (22). If one were to accept Staleys claim that the opening paragraph acts as an overture for the novel, it could then be argued that death and paralysis ar e not to be seen as separate entities in the context of Dubliners, but that the two are directly related, if not intertwined. Father Flynn, through his physical paralysis, comes to embody many of the characters in Dubliners, the majority of whom are paralyzed to some extent, whether it is physically, mentally, or emotionally. Later, the reader witnesses the manner in which death interrupts or arrests the living, as the narrator lays in the dark of [his] room and imagines that he sees the heavy grey face of the paralytic (Joyce 11). Already, one can intuit that the dead play a haunting role in Dubliners, as Gothic elements are common to modernist literature. This is evidenced here, as the narrator feels that he is smiling feebly like the paralytic priests cadaver (11). Indeed, at this point the living and dead start to merge as a single image, with the narrator mirroring the state of an immobile Father Flynn. In his critical essay on The Sisters, Corrington states that the boy and the old man fuse briefly through this smile, which contrasts elements of youth and death (24). The innocence of youth is tainted early in Dubliners, as death and Father Flynns deathly influence permeate The Sisters, looming behind both reader and narrator like an ominous shade. The child narrator may very well be a reflection of the reader, mirroring the thought processes that lead to a simultaneous realization of deaths paralyzing nature in the world of Dubliners. The narrators epiphany on deaths paralyzing quality is inadvertent, even ironic, as he calls attention to a sensation of freedom as if [he] had been freed from something by his death (Joyce 13). His actions in the story are contrary to this supposed sense of freedom; it becomes apparent that Father Flynns influence fills the silence that he left behind and acts as an interrupting force. Such a force bears similarities to the dead Catherines effect upon Heathcliff in Wuthering Heights, where the latters life is dominated by her memory. Indeed, the narrator goes so far as to anthropomorphize paralysis as a maleficent and sinful being that fill[s] [him] with fear, yet he long[s] to be nearer to it and to look upon its deadly work (Joyce 9). The boy is both repelled and oddly compelled by the paralysis he experiences here, which exposes his inability to be truly free from Father Flynns death. Therefore, paralysis can be regarded the work of death, as both the boy and his sisters find the mselves utterly torpid in the wake of Father Flynns passing. The boys inability to find any fraction of freedom from Father Flynns death becomes more evident as his mental haunting persists. Here, the child imagines the heavy grey face of the paralytic and feels the apparition follow [him] (Joyce 11). Father Flynn is referred to synecdochically here, defined by a heavy grey pallor that suggests death incarnate, further melding themes of death and paralysis. More importantly, perhaps, the narrator has rendered Father Flynn incomplete, a gnomon by definition. Joyce employs the Euclidian definition of gnomon: a remainder after something has been removed (Joyce 9). This depiction of Father Flynn becomes significant later when one considers who is left more complete by the end of the story, and further relates to Heathcliff of Wuthering Heights, who is left incomplete by his loss of Catherine, making him a gnomon of sorts as well. Nonetheless, this point illustrates the narrators inability, or perhaps reluctance, to be freed by Father Flynns passin g. Indeed, it seems significant that he imagine[s] Father Flynns face rather than dreaming about it, which would indicate a sort of conscious rejection of letting the dead be truly dead. In Dubliners: A Students Companion to the Stories, Werner states that when contemplating the word paralysis, the boy attributes to it an active presence that he wishes to observe rather than evade, and the same can be said about the concept of death for the narrator, as both themes are interlaced throughout the story (45). The development of consciousness in regard to death and its paralyzing quality is central to The Sisters. This development points to the storys role as a beginning, as the maturation, or lack thereof, of the various narrators consciousness and perception later becomes a major issue throughout Dubliners. Epiphanies are abundant in Dubliners, as they are in Virginia Woolfs To the Lighthouse, T.S. Eliots The Wasteland, and other modernist literature; nonetheless, as Werner notes in Dubliners: A Students Companion to the Stories, Joyce only gradually focuses his attention on the experience of revelation (47). Furthermore, the increasing complexity of his epiphanies is basic to the mature voice capable of articulating the contingent experiences of truth as an ongoing process for character, author, narrator, and reader (55). Such a development can be seen in the various protagonists encounters with death in Dubliners. In particular, The Sisters represents a beginning for both reader and na rrator. Just as the boy is experiencing his first encounter with death, the reader is experiencing his first bitter taste of life within the world of Dubliners. As a result, there is a simultaneous introduction to life and death. The moment of realization in the penultimate paragraph displays the narrators perception of death, as he states simply that the old priest was lying still in his coffin as we had seen him, solemn and truculent in death (Joyce 18). Here, the narrator still attributes a certain sense of hostility to Father Flynn as if to further affirm the haunting qualities of his death. The detached style in which Joyce imparts this realization is important, as it indicates that the narrator is barely cognizant of anything beyond the dead body. As Beck states in Joyces Dubliners: Substance, Vision, and Art , this realization communicates no incredibly precocious philosophical breakthrough, but the verisimilitude of a dawning awareness, a gradual, hushed, yet decisive epiphany (Beck 43). More importantly, the boy does not seem conscious of his paralysis as later narrators, such as Gabriel Conroy and Duffy, are. If the opening story is essentially a framing device, one can assume that the child narrator in The Sisters exhibits the start of a vicious cycle of internalizing paralysis. Werner claims that the narrator of Araby represents the first stage in the development of a destructive solipsism portrayed in adult characters such as Duffy, but one can argue that this stage actually begins with the narrator of The Sisters (54). Furthermore, Beck notes that the narrator of the Sisters eventually realizes his identity just that much more, and with it his secret isolation (43). Indeed, the core of the story is the boys beginning to see into himself as to the life around him, specifically the impedance of death upon that life. Death is the catalyst for epiphanies in both The Sisters and A Painful Case. In the former example, death triggers an emotional paralysis in the living, while in the latter story, death causes a realization of Duffys pre-existing emotional paralysis. Here, it is important to expound upon the significance of the narrators youth in the story. As Werner notes, the stories of childhood in Dubliners picture early confrontations of young boys with their corrupt environment (41). In The Sisters, such an environment is marked by an inevitable convergence of the living and the dead wherein the latter haunts the former. The young narrator is paralyzed by the external circumstances of his life, as Werner would argue. In fact, Werner goes on to claim that such a suffocating experience encourage[s] even the more sensitive à ¢Ã¢â€š ¬Ã‚ ¦ children to accept and internalize paralysis, which leads directly to adult counterparts who have surrendered utterly to paralysis (41, 42). James Duffy, the protagonist in A Painful Case, exemplifies the adult Dubliner who has repressed his emotional paralysis for entirely too long, measuring his life in coffee spoons in the same manner as J. Alfred Prufrock. Silence is introduced in the opening paragraph as yet another motif to be associated with death. As mentioned, the narrator of The Sisters characterizes the very presence of Father Flynns corpse with an antagonistic silence. However, one should note the relationship between Father Flynns silence and the sisters referenced in the title, as the two entities are almost at odds with one another. As the story progresses, the sisters keep attempting to break the persistent silence with their patter, but the dialogue is only ever about Father Flynn. In this manner, the dead haunt even the speech of the living. Corrington remarks that the old man has had a certain degree of ascendance over [the sisters] and even in death, he is their primary concern (22). Corringtons comments are primarily concerned with the sisters as a symbol of devoted service to the Catholic Church, the notion of Father Flynns ascendance and enduring presence speak to the haunting nature of the dead. Father Flynn is neve r more than a cadaver in The Sisters, yet his influence is undeniable. He looms over the environs silently, but to such an extent that the silence becomes a malevolent force. Rabate comments on the nature of silence in the context of Dubliners, writing that silence can finally appear as the end, the limit, the death of speech, its paralysis (33). If one works within the notion of silence as an antagonistic opposition to speech, the final moments of The Sisters can be seen as the ultimate paralysis inflicted by the dead Father Flynn. Joyce ends with Elizas speech, interrupted by ellipses before it finally trails off, imparting a paralyzing silence upon the reader. It is as if the characters, like J. Alfred Prufrock, are left wondering the same: how should I begin? Joyce extols little intimation of hope within the world of Dubliners, where the living portray an emotionally paralyzed life equivalent to that of the dead. It is only upon further examination that one can argue that Joyce actually glorifies death to some extent and indicates it as a more amenable condition. Although the eponymous sisters dialogue throughout the story is rife with clichà ©, a particular assertion is striking. Eliza declares that Father Flynn had a beautiful death, which brings to mind Joyces claim that death is the most beautiful form of life (Joyce, Dubliners 15; Joyce, James Clarence Mangan 60). She goes on to say that Father Flynn make[s] a beautiful corpse, which contrasts the paralyzed depiction of his earthly life. In fact, Father Flynn is marked by a certain incompleteness from the opening paragraph of The Sisters, when the narrator associates the priests paralysis with the word gnomon (Joyce 9). As mentioned, the narrator only represents Father Flynn symboli cally-by his face-which further suggests an incompleteness. Finally, the broken chalice symbolizes the beginning of Father Flynns broken state-his burgeoning madness. Another definition of the word gnomon is applicable to Father Flynn; as discussed in lecture, it is a shadow cast as on a sundial (66). Father Flynns influence as a deathly shade is undeniable, as he lingers throughout the story. On the other hand, his being, or lack thereof, serves to illuminate the partial, reduced lives of Joyces Dubliners, which seems to be Joyces ultimate goal here (66). The storys explicit concern with the dynamic of life and death is a deliberate one, as Joyce carefully arranged the order of stories in Dubliners (Beck 42). Indeed, the exploration of life and death is both central to modernity and the major crux upon which Dubliners is unified. Thus, Becks concern with the meaning and interpretation of the story are secondary to revealing the manner in which it functions as an overture to the novel (42). Ultimately, The Sisters establishes a pattern of the dead impacting life to the point of paralysis that is not altered until the final story. The Sisters makes it possible to explore the later stories of Dubliners in the context of themes and motifs set forth from the very beginning. Werner states that the remainder of Dubliners fulfills [the narrators] longing to be nearer to paralysis and its deadly work, which is an accurate assessment, as Joyce continues to develop this particular theme throughout the work (35). It is this inexplicable, paradoxical longing that harkens back to the poetics of modernity and notions of the sublime. The Sisters functions as an overture for Dubliners, introducing the themes and motifs that serve to unify the novel. Death and paralysis are intertwined throughout Dubliners, as they are in many other modernist works. Paralysis is present not only in The Sisters, but in A Love Song for J. Alfred Prufrock, in which the titular protagonist wonders endlessly, do I dare? The impact and implications of death can be seen as well through the influence of Father Flynn. Like Catherine of Wuthering Heights, he hovers over the lives of others like a shade, lending Gothic elements to an otherwise realistic, if stagnant depiction of Irish life. These themes provide an appropriate context-a modernist context-in which the rest of the novel can not only be enjoyed, but properly engaged.

Effects of Smoking Cigarettes Essay -- Nicotine Cigarettes Tobacco

The History of Tobacco In 3000 B.C the Ancient Egyptians burnt sweet herbs and frankincense when sacrificing to their gods. This was the beginning of smoking. Then in the beginning of the Christian era smoke was inhaled through the burning fur of a hare, the diagnoses for epilepsy was the inhalation of smoke from a goat's horn and for consumption, smoke inhaled through a reed of dried dung of an ox. Somewhere in the United States was believed to be the birthplace of tobacco, a plant of the genus Nicotiana. How and when it was discovered is unknown (Huron Indian myth has it that in ancient times, when the land was barren and the people were starving, the Great Spirit sent forth a woman to save humanity. As she travelled over the world, everywhere her right hand touched the soil, there grew potatoes. And everywhere her left hand touched the soil, there grew corn. And when the world was rich and fertile, she sat down and rested. When she arose, there grew tobacco). What is certain is that tobacco smoking was practised among the early Mayas, probably in the district of Tabasco, Mexico, as part of their religious ceremonies. The Mayans had no paper to wrap their tobacco in so they wrapped it in palm leaves or cornhusks, and stuffed it into reeds or bamboo. On the other hand they also smoked rolled tobacco leaves as crude cigars. Indians further north made pipes, some with a bowl and mouthpiece, others shaped like a Y, and placed the forked ends into their nostrils. They also blended their tobacco with other herbs and plants to vary the flavour. In South America, the Aztecs smoked and took snuff. Elsewhere in the American continent, tobacco was chewed, eaten, drunk as an in... ...f cigarettes a day. If you want to find out how much an average smoker pays for cigarettes per annum you do this: ÂÂ £4.33 (a packet of cigarettes) ÂÂ ´ 7 (days per week) = ÂÂ £ 30.31 (amount paid for cigarettes a week) ÂÂ £ 30.31 (amount paid for cigarettes a week) ÂÂ ´ 52 (weeks per year) = ÂÂ £1576.12 (amount paid for cigarettes a year) So an average smoker pays approximately ÂÂ £1576.12 a year, so if you take up smoking you are more than likely to spend more than ÂÂ £1500 a year in cigarettes. In the U.K the price of a pack of 20 premium brand cigarettes currently costs ÂÂ £4.33, of which ÂÂ £3.45 (80%) is tax. Thus out of the ÂÂ £1576.12 spent a year by a smoker 80% is taken by the Government, which is ÂÂ £1260.90. This is the main reason why the Government doesn?t ban smoking, because they are making ÂÂ £1260.90 per smoker per year in the U.K.

Successful Property Development

Throughout this paper the masculine gender is used when referring to developers. This is purely for convenience and does not imply that successful developers have to be male. Demand for new buildings from tenants and owner occupiers is the basis of all commercial property development in the United Kingdom. A typical development scheme will be initiated by a developer identifying a demand for a new building or buildings in a certain location. A major office user for example may wish to combine a number of regional offices into one new building able to accommodate new echnology and enable all of the Company's departments to be housed under one roof. The image to be presented by the new building will also be important and the Company may prefer a prominent town centre location with easy rail access or a fringe of town location on the motorway network. The experienced developer will know that if a development is to be successful the location must be the one which will appeal to tenants or purchasers who will either pay rent or a capital sum to occupy the property. There are many examples of unsuccessful schemes which failed because of poor location. With shopping centre evelopment the choice can be very subtle and a slightly ‘off-pitch' location may be enough to discourage tenants from leasing shop units in the new centre. If a site for a new development is identified and the site (or redundant buildings) is available for purchase, planning consent for the scheme must be sought from the Local Authority. It is usually the case that the developer will have concentrated on those locations where the planners will support development proposals and planning consent is likely to be received. If the location is correct and planning consent is likely the developer must also rrange finance to buy the site, build the scheme and let (or sell) it. He may also wish to sell the completed income producing investment. If he does so and the money he receives from the sale of the investment is more than the capital and interest he borrowed to build the scheme, he will receive a monetary profit. There are many sources of finance for developers but conventionally money will be borrowed from banks to buy the site and build a scheme with long term finance being provided by life assurance funds and pension funds. Long term finance in this ontext means the purchase of the completed investment by the fund which will enable the developer to repay all his short term debt and (hopefully) give him a profit. The investment market and development market are therefore closely linked and the developer will be mindful of the fund's requirements from the start of the development process. The most common form of development funding which involves the institutions if known as ‘profit erosion, priority yield'. This method allows the developer to borrow most of his short term finance from the institution and not pay it back until the cheme is completed and let. At this time the fund takes over the scheme in return for providing the developer's short term monies. The developer departs with a lump sum fee for carrying out the project which will be calculated by capitalising that amount of rent from the scheme which will be calculated by capitalising that amount of rent from the scheme which exceeds the fund's required return on the money lent; in other words its ‘priority yield'. Even if the rent from the scheme does not exceed the fund's priority yield, the developer will still receive a fee but obviously not as uch as he would get if he lets the building(s) at a high rent. There are many other types of development funding some of which are described in ‘Property and Money' by Michael Brett (see the bibliography at the back of this booklet). The developer will employ a professional team to design and cost the proposed building. The architect as leader of the design team has a crucial role to interpret his client's intentions and produce a design which will meet the requirements of tenants, planners and long term funders. Other commentators such as journalists, he general public, and the Prince of Wales may also criticise the design of a scheme where it is perceived to be ugly or inappropriate for its location. Successful commercial development requires therefore a combination of good location, planning consent, good design and funding. Even if these factors are present the scheme may still fail, at least in the short term, if the economy is weak and firms cannot expand. This introduction provides a resume of a typical development and the process can now be considered in more detail. The Developer The developer is the instigator of the scheme. He provides the entrepreneurial flair to identify the development opportunity and bring it to a successful conclusion. In doing so he will make use of established relationships with commercial estate agents and his knowledge of the occupier market. Most large development companies specialise in particular areas of the market. Slough Estates for example, built its reputation in the development of industrial and warehouse property whereas Hammersons developed the first shopping mall in the United Kingdom at Brent Cross. Some life assurance funds act as their own developer and one example is Norwich Union in the development of the Bentalls centre in Kingston on Thames. Various government agencies also act as developers such as District and Regional Health Authorities with hospital building. Increasingly, the newly privatised utilities will carry out their own developments. There are many types of developers. Some are ‘developer traders' who build with a view to selling the scheme when it is complete. Others will develop and hold the completed investment in their investment portfolio. Some developers are quoted on the stock exchange and others are little more than one man bands. Throughout the development process, but crucially at the start before funds are committed, the commercial developer will carry out an appraisal which will predict the eventual profits to be earned from the scheme. A considerable amount of work has to be done to produce a full appraisal as all the costs of the scheme have to be considered. The site itself will have to be fully investigated and this will involve bore hole surveys to enable the structural engineer to estimate the cost of the foundations. An environmental impact study may be required before planning consent is forthcoming. With the assistance of his agent, the developer will also predict the rent which the scheme will produce and (if the investment is to be sold), the investment value. If a scheme is to be successful the investment value less all capital and interest costs will have to leave an acceptable profit. If a developer has used rents in the appraisal which are too high, perhaps in expectation of rent rises in the development period, he may eventually make no profit at all and the scheme (from the developer's viewpoint) will have failed. To avoid risk and to attract other tenants to a development, a developer will often eek a pre-let tenant for a scheme. Before construction starts, a tenant will sign an agreement to lease all or part of the scheme at an agreed rent. This is particularly valuable in shopping centre development where an anchor tenant such as a department store will make a commitment before development commenced, thereby giving confidence to other lessees to take shop units. A developer who borrows money to buy a site, construct a building, and seek lessees will have no appreciable earnings until the scheme is let. It would be difficult therefore, for any interest on capital borrowed to be repaid during the development period. It is usually the case that interest is repaid as a lump sum when the fully let investment is eventually sold. Interest in these circumstances is said to be ‘rolled up' until the end of the development period. In arranging finance, the developer will often have a short term interest in the scheme, whereas the fund purchasing the investment when fully let, has a long term interest. Funds are, therefore, particularly interested in tenant quality in the longer term and building flexibility which may not be of primary importance to the developer. Local Authorities may initiate development, particularly retail, by making town centre ites available on ground leases to developers. The Authority will have a long term interest in the scheme's success, as they will receive a grounds rent, probably geared to the full rental value of the development. Not all developers have a short term interest in a development. Major developers may hold completed investments in a portfolio rather than ar range long term finance by selling the investment to a fund. Planning In the words of Clara Green ‘planning applications (like prayers) receive one of three answers – yes, no or yes but. ‘ The process can be one of great frustration and ifficulty for developers and for a major scheme it is usual for a specialist planning consultant to be employed to negotiate a consent with the Local Authority. Planning law is complicated but in general terms, planning consent is required for most major building in the United Kingdom. The department of the Environment is responsible for planning and the Secretary of State for the Environment is advised by teams of professional planners, surveyors and architects. All applications are made to local councils and it is only the most important or controversial applications which will be of interest to the higher tier of overnment. Most applications are, therefore, decided locally although the Secretary of State may decide to call in any application at his or her discretion. To obtain planning permission, an application will be made to the District Council although applications in the future also may be considered by the new unitary authorit ies. The developer can choose the type of application he wishes to make. If he wishes to seek approval to the principle of development, he can make an outline application. This is sometimes referred to as a red line application, as a red ine is drawn around the site plan supporting the application. If consent is granted, this will be subject to reserved matters and the developer will have to seek a subsequent consent for these detailed matters later. Alternatively a full application may be made which will include all detailed matters as well as the basic principles. The Local Authority will decide the application in the context of plans which will have been previously published and approved by the Secretary of State. Under the present two tier system of Local Government, the County Councils produce structure lans for their area which show in strategic terms the type and location of development which will be permitted during the period of the plan. The District Councils produce local plans which deal with detailed matters related to specific areas of land. If the planning application does not accord with the local plan, the Local Authority will be justified in refusing the application but obviously a developer would be unwise to make an application of this type. Structure plans have a life of between 5 and 15 years and comprise a lengthy written statement supported by explanatory diagrams. The important matters dealt with in the structure plan are strategic matters such as tourism and leisure, waste disposal, new housing, employment and transport. The Authority has a two month period in which to decide an application but it can ask the applicant for more time. If the application is refused the applicant can appeal to the Secretary of state and the matter in the majority of cases, will be decided by a Government Inspector. In major cases, the Inspector will make recommendations to the Secretary of State who will, after advice, take a decision. There may also be a Public Local Enquiry here evidence is heard by the Inspector over a number of days from all interested parties. In producing their structure and local plans as well as deciding applications, Councils have to take into account policy statement produced by the government. These are called Planning Policy Guidance Notes (PPGs) and they are published or amended from time to time. Two of the most important are PPG 6 which relates to out of town retail development and PPG 13 which deals with transport. There are a total of 25 PPGs and many are frequently revised. For example a new PPG 12 was produced in April 1999. This revision emphasised the importance of regional planning which now has it own PPG (PPG 11) and also stressed the government's commitment to a plan led system. Any developer seeking to build against government guidance as stated in the PPGs faces a long, expensive and uncertain battle and therefore is well advised to tailor development proposals to accord with published guidance. The government is at pains to demonstrate that the plan led system is sensitive to demographic changes and this is seen in the revisions to PPG 3 (Housing) which take account of the prediction that ‘7 out of ten new ouseholds forming over the next 20 years are likely to be single person households' (Nick Raynsford, Housing and Planning Minister). A topical revision PPG 25 (Flood Risk) which aims to avoid development in flood risk areas and emphasises a precautionary approach in marginal areas with flood defences to be shown to be in place (and paid for by the developer) before development is approved. The Development Team The team will be employed by the developer at the start of a project and it role will encompass design, costing, funding and marketing. In summary its functions are as follows: Architect The Architect is the leader and coordinator of the design team who has a major role in interpreting his client's requirements and producing a design brief. The brief establishes the client's basic requirements and from this the Architect and other members of the design team will produce detailed design drawings. These will eventually be given to selected building contractors who will tender for the job of constructing the building. During construction, the Architect will inspect the work as it proceeds on behalf of his client. Because the Architect's work is so important he ill be paid a fee based on a percentage of the total cost of the building work. For a new building this will normally be between 4% and 5% of the cost of the work. Quantity Surveyor The Quantity Surveyor estimates the eventual cost of the new building and will produce regular cost checks as the design is developed. Before tenders are invited from building contractors, he will inform the client of the estimated cost of the works (the pre-tender estimate) and the client can then proceed to tender with confidence. Services and Structural Engineers In some instances the engineers will be responsible for producing design drawings nd specifications of the building services (air-conditioning, electrical installation etc) and the structure (foundations, structural frame). Increasingly however, the services engineer will only produce a statement of how the services will perform (a performance specification) rather than a full design. In these circumstances, design becomes the responsibility of the contractor. Estate Agents Developers usually have established relationships with firms of estate agents who will be aware of development opportunities. The agent will also provide marketing advice and will be responsible for letting the building. Other Consultants Other consultants include solicitors, landscape architects and planning consultants. With some complicated and large schemes, a project manager may oversee the project on behalf of the client. Specialist noise or environmental consultants may be required where development will take place in environmentally sensitive areas where special planning conditions have been imposed. Successful Schemes A scheme will be successful if its location and design has attracted a number of first class tenants and will continue to do so in the future should any tenants vacate. A uccessful scheme will provide a secure and growing investment for the eventual long term investor as well as an adequate monetary profit for the developer. There are many reasons why development schemes are unsuccessful, some of which are discussed below: Poor Location This is the most obvious but nevertheless very common reason for failure. A shopping scheme may be located where there is a lack of pedestrian flow. An office building may be located where vehicular access is difficult or the chosen site does not provide the required image and identity for the tenant/s. On a wider scale, he development may be located in a city which is in decline, to the detriment of long term investment quality. Some commentators are casting doubt on the future quality of fringe of town retail warehousing schemes which do not have the support of an established town centre. Poor Design A shopping centre must be designed to maximise pedestrian flow and enable shoppers to both park and gain easy access. If the design fails to do this, the public may avoid the centre and tenants will be hard to find. Also shopping centres must allow frequent changes of image and must provide the correct ambience for the ublic. Attention to detail with the internal design will allow this to benefit the investment. Thee are many examples of office buildings constructed in the 1960's and 1970's which do not provide the necessary ducting and image for modern tenants using today's technology. These developments may have been regarded as successful when they were first constructed, but in terms of a long term investment are of dubious quality. Lack of flexibility with many buildings means that where occupier requirements change the buildings cannot and voids are the result. Increased Costs during Design or Construction If a developer allows costs to increase, he will eventually make no profit whatsoever from the scheme. If costs increase beyond those used in the appraisal the developers profit will be eroded. The expertise of the design team to contain costs whilst, at the same time, producing a quality building is of vital importance but sometimes mistakes are made. A lack of coordination between building work and services is a typical example leading to redesign, delay and increased costs. Planning Errors When a contract is awarded to a contractor, it is important that the site of the evelopment is firstly in the legal control of the developer and secondly the same site for which planning consent has been granted. There have been many examples of mistakes in this area to the detriment of the project. Empty Property A newly built shopping centre with few tenants is clear evidence of a scheme which falls short of success. There are many examples amongst those centres completed during the recession. As with office and warehousing property pre-let tenants are particularly valuable in recessionary periods. Public Sector Development The Private Finance Initiative. In the past public sector development such as roads, hospitals and bridges were built by government contracting with the private sector for the design and construction works. Civil servants and their consultants would work to precise specifications of what was required to be built. When the development was complete the government would then be responsible for running the completed hospital, road or whatever to the benefit of the public. The Private ~Finance Initiative (or PFI) is intended to revolutionise the traditional method of producing public facilities described above. It was conceived in 1992 during Norman Lamont's troubled chancellorship and was vigorously supported by his successor Kenneth Clarke. In essence PFI only required the government to state how the building is to be used and the performance it must achieve. The private sector is then invited to tender for the design, construction and running of the new facility. The reward for doing this is negotiated with the government agency responsible for the facility and will usually take the form of a regular monetary payment so long as the facilities provided continue to meet the agreed criteria. Kenneth Clarke stated that PFI is ‘a radical and far reaching change in capital investment in public services which will break down further barriers between the public and private sectors'. The central argument in favour of PFI is that the private sector is more capable of promoting efficiency than government and will provide business solutions to public sector requirements. It is also argued that the risks of increased construction and running costs, which appears to be a feature of public sector schemes, will disappear with PFI where all the risks are borne by the private sector. Critics of PFI point out that it is extremely difficult to produce a performance specification for, say, a highly complex building such as a hospital and this will lead to private sector contractors being allowed to cut corners to the detriment of the public. It is also pointed out that the government can always borrow money more cheaply than the private sector and that this will inevitably lead to increased costs which will be passed on to the public. The change of government in May 1997 led to a thorough review of the experience gained from using PFI in the previous five years. Malcolm Bates was appointed to arry out a review which resulted in 29 recommendations aimed at rationalising and reinvigorating the PFI process. The ‘Treasury Taskforce' was the government's response to the review and this body consisted mainly of city financiers who were charged with building up PFI expertise in government. The taskforce had a life of three years and is replaced by ‘Partnerships UK' which will operate as a joint private/public consultancy to assist with the PFI process. There are currently hundreds of PFI schemes in the process of completion and the present government is wedded to this form of procurement for public sector projects.

To Obey or Disobey

Obedience is an age old expectation that rulers, priests, and government officials have required for years from their subjects. Most of the time individuals follow their leaders without question. This is the case because the population from which obedience is required believes that they continue to have a choice. When, for whatever reason this belief is lost, some individuals will begin to exhibit an increasing disobedience to the requirement. This often increases to the point of violence or, the case of a country, war. While there are all types of disobedience, this paper will discuss civil disobedience and the social pressure often associated with it. A good example of this type of cycle can be found in the historical background of the United States. When the United States was first populated by Europeans it was a colony of Great Britain. Over the course of several decades, the British king imposed a series of taxes on the colonists. Most colonists felt that they were being taxed without any representation. Over the course of approximately 15 years the protests against the taxes became increasing violent until the Continental Congress was formed in 1775 (History Central). With Thomas Jefferson serving as the writer, the Declaration of Independence was drafted by the Congress and sent to the King of England. In it, Jefferson wrote, Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security (Ushistory) The Revolutionary War was fought and freedom from British rule was won. Today the population of the United States is expected to pay taxes. The difference is that people believe the choice is theirs because of our representative form of government. In the mid 1800s, Henry David Thoreau introduced a new concept that has greatly influenced individuals and groups desiring change since then. Thoreau spent several years living in a simple cabin near Walden Pond in Massachusetts. During this time the United States still allowed slavery. Thoreau was opposed to this. He refused to pay taxes as a form of protest. His explanation evolved into an essay entitled â€Å"Civil Disobedience†. Basically Thoreau felt that an individual should not support by any means a government that was engaging in acts of which the individual did not agree. He felt that the individual should be willing to suffer the consequences of his disobedient act, however he/she should never take a violent stand in defense of his/her belief (Williams). Today â€Å"Civil Disobedience† is considered to be the basis of several modern nonviolent resistance movements. â€Å"It is known to have been an inspiration to Mohandas Gandhi, who led the passive resistance movement for the liberation of India from British colonial rule. Thoreau’s ideas also influenced Martin Luther King, Jr. s Civil Rights movement and the American struggle to end the Vietnam War† (Williams). During the fight for equal rights for Black Americans that took place in the 1950s and 60s, Martin Luther King Jr. relied on the principle of civil disobedience written a century earlier by Thoreau. While incarcerated in the Birmingham, in a letter known as the â€Å"Letter from the Birmingham Jail†, King wrote, â€Å"Over the past few years I have consistently p reached that nonviolence demands that the means we use must be as pure as the ends we seek. I have tried to make clear that it is wrong to use immoral means to attain moral ends. But now I must affirm that it is just as wrong, or perhaps even more so, to use moral means to preserve immoral ends† (King). Others followed Dr. King’s example of non-violent protest. One evening in December, 1955, on her way home from her job in downtown Montgomery Alabama, a woman, Rosa Parks, was asked to give up her seat to a white passenger on the bus she was riding. She refused. She was arrested and fined. This simple action inspired the Montgomery Bus Boycott. By June of 1956, the court declared Alabama's racial segregation laws for public transit unconstitutional. The city appealed and on November 13, 1956, the Supreme Court upheld the lower court's ruling. . . The city of Montgomery had no choice but to lift the law requiring segregation on public buses† ( Bio. True Story). Groups of individuals, when convinced that it is no longer acceptable to conform to the expectation of the ruler can make historical changes in the world in which they live. What causes one individual to become disobedient and another to remain obedient to the group rules? Most people want to believe that they think for themselves; however, when an individual is part of a social group that person will began to assume the group’s ideas and rules. Individuals may then find themselves engaged in a struggle in which they do not believe because of the social pressure to fit into a group. Additionally they may fear being an outcast. This is especially true if friends or family belong to the same group. Doris Lessing wrote â€Å"When we’re in a group, we tend to think as that group does: we may even have joined the group to find â€Å"like-minded† people. But we also find our thinking changing because we belong to a group. It is the hardest thing in the world to maintain an individual dissident opinion, as a member of a group†. (724) Universities over time have done a lot of research trying to understand why people obey and disobey. Most people believe they are good and trustworthy. These individuals feel no matter what occurs they will always try to do the right thing in their day to day life. In The Perils of Obedience, Milgram tells of a woman â€Å"that the last shock she administered to the learner was extremely painful and reiterates that she did not want to be responsible for any harm to him†. 695). Despite her desires she still administered the shock, thus being obedient to the person in charge and not to what she believed. Individuals who still believe in the concept called into question by the disobedient group, often feel intense pressure to maintain loyalty to the old ruling entity. In Doris Lessing’s article, Group Minds, she states â€Å"But the majority will continue to insist-speaking metaphorically-that black is white, and after a period of exasperation, irritation, even anger, certainly incomprehension, the minority will fall into line†. Pressure to conform can manifest itself in another way as well.. Individuals may feel compelled to follow the ideas and rules of someone else and follow that group of people no matter what path it my lead them down or where those ideas and rules may take them. Social pressure comes from everywhere; family, church, friends, jobs, co-workers, and etc.. During the height of the segregation movement in many of the minds of the south there are only two sides in this fight; for segregation or against segregation no fence riding. This concept is also apparent during times of conflict. For examples, during the Revolutionary War many colonists remained loyal to Great Britain. British sympathizers were called Tories. They often â€Å"agreed with the patriots about â€Å"no taxation without representation. † But they wanted to solve the dispute in such a way as to remain in the British Empire† (US Anabaptists). Following what you believe to be right will have consequences. For example, those wanting freedom from England formed a new country and enjoyed many rights and freedoms. All those remaining loyal to the king were considered traitors. â€Å"Most of the new states passed laws taking away the loyalists' property. Patriot mobs attacked prominent Tories. Those found helping the British were imprisoned† (US Anabaptists).. Most people want to believe that they think for themselves; however, when an individual is part of a social group that person will began to assume the group’s ideas and rules. Individuals may then find themselves engaged in a struggle in which they do not believe because of the social pressure to fit into a group. Additionally they may fear being an outcast. This is especially true if friends or family belong to the same group. Doris Lessing wrote â€Å"When we’re in a group, we tend to think as that group does: we may even have joined the group to find â€Å"like-minded† people. But we also find our thinking changing because we belong to a group. It is the hardest thing in the world to maintain an individual dissident opinion, as a member of a group†. (724) In conclusion, it appears that a person is either obedient or disobedient based on the group to which he/she belongs. Inclusion in a particular group may be based on family culture as in the case of those loyal to the King in the Revolutionary War or those engaged in keeping in tact the segregated nature of the South before 1965. Other groups include religious groups, political groups, and special interest groups. While as a people we may like to believe that we think for ourselves, the facts point in a different direction. It would take a brave person indeed to stand on principles in the face of objections from the group to which he is most closely associated.

Mnc Staffing Practices Essay Example

Mnc Staffing Practices Essay Example Mnc Staffing Practices Essay Mnc Staffing Practices Essay The three issues I will discuss is the pay differences between Asians and whites, and other minorities, how they exclude others from attending meetings by conducting them In Japanese and how they are using stereotypes to refrain from holing Americans. Compensation is one of the most complex areas of international human resource management. Pay systems must conform to local laws and customs for employee compensation while also fitting into global NC policies (Hailed, 2002, Para. ). It would only be fair to pay those with similar position the same pay rate. In addition to the compensation problems how they conduct their meetings were wrong. It states In this case that weekly meetings were conducted In Japanese, effectively excluding non-Japanese-speaking employees (Vance, 2006, peg 170). This clearly means that their intent was to exclude them from being a part of important matters and making them feel as if they didnt belong even though they were executives who supposed to be included in those meetings. Marianne America also used stereotypes as a reason to not staff certain individuals. For Instance, In an email the vice president stated, l want a person who has aggressiveness, high I. Q, 23 to 30 yr old, Asian, Like Chinese, Japanese, of course American or others Is fine. In this one sentence they discriminated in two ways. The first is discrimination based on age and the second is discrimination against ethnic group and national origin. Basically he wanted a specific type of person. Macs needs to follow the employment laws of the united States because if they are allowed to operate here they should be subjected to the same polices other corporations have to follow. Discriminating against people from different ethnic backgrounds and national origins is wrong in all cultures and it shouldnt be tolerated. In addition, there should be penalties for violating U. S. Employment laws.

Popular Music Essays - Counterculture Of The 1960s, Free Essays

Popular Music Essays - Counterculture Of The 1960s, Free Essays Popular Music Popular music is: "music that is enjoyed by the largest possible audience." It includes country music, folk music, rhythm and blues ( R musical comedy, jazz, marches, rock n' roll, and ragtime. Popular music is primarily listened to by young people. In his book, Sound Effects, Simon Frith said that popular music has been about growing up, and that it has been like this since the beginning of the century.1 However, the popular music industry is based largely on the sale of records. However, popular music can also do many great things for society. Harry Belafonte once said "A funny thing happened to the world in 1985, it cared."2 In the 1980's, many benefit concerts such as Live Aid and USA for Africa were held to raise money for people who were in need of help. Other benefits such as Hands Across America and Farm Aid showed that the listeners could get involved too. Popular music reflects the outlook of the listeners of that time period. The death of friends and family members during the first world war hardened people very much and this was reflected in the lifestyle of the twenties. There was much women's suffrage during this time. People began to smoke and drink more often, and generally became more irresponsible. Jazz had much musical freedom. It represented the way many people were feeling. Not everyone was smoking and drinking too much though. Many people still continued to lead highly respectable lives. For these people were the conventional songs. The big stage musical of 1921 was 'Blossom Time' which hit song was called 'Song Of Love.' This kind of song made people happy, something that was much needed in this post- war time.3 The teenagers of the twenties, on the other hand, were said to be carefree. 'Ain't We Got Fun?' by Dick Whitings was said to be a perfect theme song for that generation.4 The young people of that time were not experiencing the same kind of grief as the slightly older people. Many things happened in the 1920's. First of all, radio was beginning to gain much power. Many things were happening in baseball. And fun- loving Ouija boards were becoming very popular. Most of the songs of the 1920's were considered proper, however there was protest over the song "If I Met The Guy Who Made This Country Dry," by Jerome- Harry ven Tilzer. There were also the conventional songs with ballads and old-fashioned waltzes. Overall, the 1920's had good songs and lyrics in popular music with much emphasis on the musical stage.6 The great depression started in the 1930's. Because of this not many people could afford to buy records. But something new emerged out of the darkness. It was the radio. People could listen all they wanted, for free. People began to stop listening to the records and depended on their trusty radio. And not only could they tune into their favorite songs, but also hear the news and other forms of entertainment. During the 1920's, at least 40 million records were sold each year. During the early 30's, about one fourth of that amount had been sold. During this time big groups of jazz musicians started to play together. It was during the swing era and was known as the Big Band era. The songs were very optimistic and could bring up the mood of the listeners, who, at this time were very depressed.7 Swing music had a very loose feeling sound. It became more popular with the popularity of the radio. Duke Ellington once said in a song "It don't mean a thing if it ain't got swing." The soloists in Duke Ellington's band were said to be "Very individualistic, playing clarinet cries, saxophone moans, and trumpet grows to his hundreds of compositions."8 One of the leaders of swing was Fletcher Henderson who organized a successful "big commercial" band. In his bands were both white and black musicians. This took away many racial tensions many people were having, by making everyone equal.9 During the thirties many people immigrated to the United States. With them they brought the music from their country. This had great influence on American music. Some immigrant composers taught music or performed in

Torralba and Ambrona - Lower Paleolithic Sites in Spain

Torralba and Ambrona - Lower Paleolithic Sites in Spain Torralba and Ambrona are two open-air Lower Paleolithic (Acheulean) sites located two kilometers (about 1 mile) apart on the Ambrona River in the Soria region of Spain, 150 km (93 mi) northeast of Madrid, Spain. The sites are at ~1100-1150 meters (3600-3750 feet) above sea level on either side of the Masegar river valley. Both were thought by excavators F. Clark Howell and Leslie Freeman to contain important evidence for 300,000-year-old hunting and butchering of mammoth by Homo erectus- a pretty revolutionary idea for the 1960s. More recent investigations and developing technologies have shown that Torralba and Ambrona do not have identical stratigraphies, and were occupied at least 100,000 years apart. Further, research has rejected much of Howell and Freemans ideas of the site. Although Torralba and Ambrona turned out not at all to be what their primary excavators thought, the importance of the two sites lies in the notion of ancient butchering and how that stimulated the development of techniques to define what evidence would support that type of behavior. Recent research at Ambrona has also supported the North African origin for the Iberian Acheulean during the Middle Pleistocene. Cutmarks and Taphonomy Howell and Freeman believed that the two sites represented the mass killing and butchering of extinct elephants, deer, and cows that took place at the side of a lake approximately 300,000 years ago. Elephants were driven into the marshes by fire, they hypothesized, then dispatched with wooden spears or stones. Acheulean bifaces and other stone tools were then used to batter open the animal skulls; sharp-edged flakes were used to slice meat and disarticulate joints. American archaeologist Lewis Binford, writing about the same time, argued that although the evidence didnt support butchering or killing, it did support scavenging behavior: but even Binford didnt have the technological advances that have dissolved the previous interpretations. Howell based his argument for hunting and butchery on the presence of cutmarks- longitudinal slices evident in the surfaces of the bones. This argument was tested in a seminal article by American archaeologists Pat Shipman and Jennie Rose, whose microscopic investigations first began to define the diagnostic features of cut marks. Shipman and Rose found that there was a very small percentage of genuine cutmarks in the bone assemblages, accounting for less than 1% of the bones they looked at. In 2005, Italian archaeologist Paolo Villa and colleagues described further taphonomic studies of the faunal assemblage from Ambrona and concluded that while bone and stone artifacts show varying degrees of mechanical abrasion, there is no clear evidence of either hunting or butchery. Animal Bone and Tool Assemblages Animal bone from the Lower Complex levels from Ambrona (dated to 311,000-366,000 based on Uranium Series-Electron Spin Resonance U/ESR) are dominated by extinct elephant bone (Elephas (Palaeoloxodon) antiquus), deer (Dama cf. dama and Cervus elaphus), horse (Equus caballus torralbae) and cattle (Bos primigenius). Stone tools from both sites are associated with the Acheulean tradition, although there are very few of them. According to Howell and Freemans two sets of excavations, ivory points were found at both sites: Torralbas assemblages included 10 and Ambrona 45, all made from elephant tusks. However, Villa and DErricos 2001 investigations of those points revealed a broad variability in length, width, and stem length, inconsistent with patterned tool production. Based on the presence of eroded surfaces, Villa and DErrico concluded that none of the points are indeed points at all, but rather are natural remnants of elephant tusk breakage. Stratigraphy and Dating A close examination of the assemblages indicates that they were likely disturbed. Torralba assemblages, in particular, appear disturbed, with up to one-third of the bones exhibiting edge-rounding, a characteristic thought to be the result of the erosive effects of having been rolled in water. Both occupations are large in area, but with a low density of artifacts, suggesting that the smaller and lighter elements have been removed, again suggesting dispersal by water, and surely by a combination of displacement, redeposition, and perhaps mixing between adjacent levels. Research at Torralba and Ambrona Torralba was discovered during installation of a railway in 1888 and first excavated by the Marques de Cerralbo in 1907–1911; he also discovered the Ambrona site. The two sites were first systematically excavated by F. Clark Howell and Leslie Freeman in 1961–1963 and again in 1980–1981. A Spanish team led by Santonja and Perez-Gonzalez ran an interdisciplinary research project at Ambrona between 1993–2000, and again between 2013–2015. The most recent excavations at Ambrona have been part of work identifying evidence for an African origin of the Acheulean stone tool industry in the Iberian peninsula between MIS 12-16. Ambronas levels dated to MIS 11 included characteristic Acheulean handaxes and cleavers; other sites supporting an African Acheulean include Gran Dolina and Cuesta de la Bajada among others. This represents, say Santonja and colleagues, evidence of an influx of African hominids across the straits of Gibraltar approximately 660,000-524,000 years ago.

Family structures are becoming more diverse. what evidence is there to Essay

Family structures are becoming more diverse. what evidence is there to support the trends - Essay Example rding to MacIver and Page a family is â€Å"a definite and long term group defined by sexual relationships that reproduce and bring up children†¦ formed by the living together of man, woman and their children.† (Dubey p. 123) So the structure of the nuclear family consisted of the husband wife and children. In other words family structure was based on 1)The relationship between husband and wife. 2) The procreation of children 3)Common residence. But if we examine the reality of today’s growing rates of divorce, single parent families as well as the trend towards gay or ‘same sex marriages’ then we can conclude that there is an increased trend towards blended families, binuclear families and single parent families. This has led the Sociologists William J. Goode to state that the institution of the family as we know it is vanishing altogether; while others state that the term nuclear family is inadequate in explaining the different contemporary household arrangements. Hence the new term ‘postmodern family’ is used to refer to the different forms of family structure including couples minus children as well as single-parent families and blended families. This diversity could be due to the following prevailing trends: Trend 1: There is a growing tendency amongst couples to live together rather than get married. The majorities of such couples have sexual relationships but do not choose to have offspring due to work and other pressures. Trend 2: There is a trend to divorce. This has resulted in children being granted living custody with either their father or mother. As a result the child moves between the homes of the two separated parents so the third element of a families structure, based on residence has also changed. Ogburn and Nimkoff’s give a more modern definition of a family by seeing the family â€Å"†¦as an association formed by the sex relations of husband and wife, with or without children.† Trend 3: There is a growing

How much has US succeeded in building democracy in the world since Term Paper

How much has US succeeded in building democracy in the world since world war 2 - Term Paper Example The Cold War, with its potential threat of nuclear conflict, was a very big threat to democracy in the world, and the United States, in the presidency of John F. Kennedy kept the world from a third major war. In this period, America played the role of peacemaker, and counter-balance to Soviet power. The difference between Communism and Capitalism expressed itself both economically and politically, and it took many years for Communism to fall, and the forces of democratic capitalism to take over. In this phase, too, America promoted democracy and proved in the end to be successful. Although America failed to establish military dominance in the Cold War, during this time from the 1950s to the 1980s America supported the creation of world agencies like NATO, the United Nations (UN), the World Trade Organization, the World Bank and the International Monetary fund (IMF). These non-state entities represent crucial attempts to spread a Western style democracy across the world. In her article about global democracy, A.M. Slaughter notes that â€Å"Power is certainly military. It is certainly economic.† (Slaughter, 2000, p. 225) and makes the point that it is in America’s own interest to promote systems and organizations which operate along American style lines. Through these agencies the United States promoted democracy and pursued its own interests at the same time. This joint objective is in fact the reason why the United States has in the end only partially been successful in building democracy across the world. Some of the military interventions that have happened seem to focus more on the United States’ desire to advance its own agenda, such as resisting communism in Korea, or fighting Islamic terrorists in Afghanistan. The line between stopping human rights atrocities, as in Kosovo, and implementing regime change as in Iraq

John Locke Second Treatise on Government vs. Voltaire Candide Term Paper

John Locke Second Treatise on Government vs. Voltaire Candide - Term Paper Example Locke attempted to explain the reasons King James II was overthrown justifiably and why he was ascended by William III. He as well wanted to define the legal role of the civil government. He defined the role of the civil government as the political power and a right of law making which includes penalties of death and fewer penalties for regulating property as well as preserving them and employing forces of executing these laws, in defense of common wealth against foreign injury. This is all for the good of the public . On the other hand, Voltaire Candide is about Candide who grows in the province of Westphalia in Germany. He is made to believe that he lives in a world that is of the best quality . This belief starts to change when he started experiencing horrors of poverty, war, the hypocrisy that the church had and maliciousness of man. According to Locke, the government was in existence, among many other things, in order to promote the good of the public as well as to protect the property, liberty and life of its people. This is what is considered to being the main point of having a government and these are the purposes for its existence (Locke 12). For the above reasons, the people who run or govern are supposed to be voted in by the entire society. It is the right of the society to hold powers of instating another government when it is necessary. Locke believes that people are free by nature. This is the belief that founded his philosophy about the government. This is also supported by Voltaire Candide. He says that the government is supposed to be in existence in order to support the society and provide them with all they need. But according to Candide, this does not happen since the people having authority were corrupt and usually abused their powers. The society’s rights and freedom were not granted and they faced a lot of hardships. There are certain literary artifacts that were used in making the different points they had. Locke argues that in case the society is dissolved, it is also likely that the government will as well dissolve. He said that it is very impossible to have the frame of any house subsist and the materials that make it are jumbled into heaps that are confused by an earthquake4. The agreement of individuals to work as a single body is what makes up a society. If the agreement brakes and the different individuals make the decision to separate, then the community will end up breaking. When the government does not have its society, the government will as well dissolve. But in case a government dissolves and the society remains as one, the people shall still have the power to reform the government as they would like. On the other hand, Voltaire Candide uses wealth in explaining his points of view. Wealth leads to greed and causes war. The need to possess wealth enco uraged robbery and abuse of power. In his work, wealth is depicted as transient. Even though it may be beneficial, it is not ultimately fulfilling5. There are different practices of their time that these writers mock or criticize. Locke criticizes the act of slavery. He says that men has a natural liberty of being free and not have any power that is superior on earth. Man is not supposed to be under any legislative authority or will of man but is supposed to have the law of nature to rule him. He also says that no man should control the right to own property. This is because God gave life to all men in common and gave them reason to use it to their advantage and convenience. Every person has the right of owning property wherever they would like to. Just like Locke, Voltaire Candide criticizes slavery in a great way. The abuse of power leads to slavery since the leaders use their power

How important is the setting in R L Stevensons portrayal of a double life in Dr Jekyll and Mr Hyde Essay Example for Free

How important is the setting in R L Stevensons portrayal of a double life in Dr Jekyll and Mr Hyde Essay The strange case of Dr Jekyll and Mr Hyde was written in 1886 by Robert Lewis Stevenson. Robert Lewis Stevenson was born and brought up in Edinburgh in the 1850s. He was part of a middle class family, his parents were strict Christians and it was very important to them that Stevenson behaved respectfully. When Stevenson was a child, Stevensons nanny frightened him with stories of hell and suffering which may have contributed to his ideas in the novel. When he was a young man in Edinburgh he may have used a false name or a hidden identity in order to indulge himself in forbidden activities or he may have fantasized about them, like crime, affairs and homosexuality. In Dr Jekyll and Mr Hyde Stevenson uses his experiences to describe the unpleasant side of life. The novel is about how Dr Jekyll leads a double life and its devastating consequences. The book reflects Victorian concerns about city life such as crime and poverty. The novel is set in the city of London and is significant in the novel because in general most gothic novels at that time were set far away or in unfamiliar surroundings, yet Stevenson sets the novel in London which shocked readers because it was a place they all knew which made them think that the themes discussed in the novel could be happening near them. This makes it more frightening to the reader and therefore made it a more popular novel. In the novel Stevenson describes London as labyrinths of lamp lighted city. This suggests that the city makes it possible for people to easily lose themselves in London. We see this in the novel when Stevenson says he was often absent; for instance, it was nearly two months since she had seen him till yesterday (the day of the murder). This tells us that Hyde was often absent and it relates back to people losing themselves in the city. Another important aspect of the setting is the weather, which for most of the novel is described as fogged city moon This creates an atmosphere of mystery and unknown and it also suggests that something might be about to happen. The chapter which describes the Carew murder case is an important event in the novel because the murder forces Mr Utterson to investigate and piece together the link between his friend Dr. Jekyll and the murderer Mr Hyde. The reader learns, however, that they are the same person. Stevenson sets the murder scene in a lane which the maids window overlooked and interestingly chooses the murder to be brilliantly lit by the full moon. He does this in order to display every detail of the murder and to show the viciousness of the attack. For example the murder is described as a storm of blows, under which the bones were audibly shattered. This tells us how brutal and violent the murder was by the maid being able to hear the victims bones being broken. It also gives the reader the full affect of the damage that had been done. The murder is particularly shocking because it enables the maid to describe the murder so well as a result of the murder scene being so brilliantly lit by the moon. The characters houses in the novel also suggest something about them, Dr Jekylls house, for example, is described as having a great air of wealth and comfort. Hydes rooms are described as well furnished, but theyre located in Soho which is a seedy area full of unrespectable people. The themes in Dr Jekyll and Mr Hyde, for example crime and concealing forbidden activities touched on issues Victorians were concerned with because it was set in a familiar place and it made people think the sort of themes discussed in Dr Jekyll and Mr Hyde could be happening around or near them. Darwins ideas about evolution and how human beings descended from apes changed Victorian beliefs. His ideas about people being evolved from apes suggest that animalistic urges and desires might be present in all men. Victorians tended to see crime as being carried out by the poor, who they thought of as being more brutish or animal like. Hyde is described as ape like but he is the other side of Jekyll, so Stevenson is saying all men are capable of brutish behaviour, regardless of their class. He is also described like this because of the brutal behaviour he shows during the Carew murder case. This suggests that Hyde is less evolved than other human beings. The reader learns however that Hyde is also Jekyll; this makes the reader think that anyone is capable of ape like behaviour. Another theme that is discussed in the novel involves people leading a double life. The idea of a double life, like the one Jekyll leads, would have appealed to Victorian readers because of the familiar background the novel was set in. Also Victorian codes of behaviour and social rules were strict and repressive, so people liked the idea of breaking out of this. In this novel the setting is important because it creates a sense of uncertainty and creates atmosphere because of the novel being set in dark and fog for most of it. Stevenson created a genre called urban gothic, this is because he set the novel in a familiar place and also at the time he wrote the book. He created a modern urban setting in order to engage his readers which mean they feel all the emotions more intensely because they can imagine it happening to them. The idea of the double life in the novel not only is of interest to Victorians but also to modern day readers because of the familiar setting. The phrase Jekyll and Hyde personality is used today when someone shows two very different sides of their personality because the book is about Dr Jekyll who leads a double life as Mr Hyde. So by saying a Jekyll and Hyde personality it is like saying a split personality. We can see many of the ideas that are in the novel in our present times for example leading a double life and this suggests that the ideas behind the novel are still as relevant today as they were in Victorian times.

Factors Affecting Velocity of a Sphere Rolling Down Incline

Factors Affecting Velocity of a Sphere Rolling Down Incline Factors affecting the velocity of a sphere rolling down an incline. An experiment was performed investigating the factors affecting the velocity of a ball rolling down an incline. After investigating how mass, angle of incline, and center of mass affect the velocity of a ball rolling down an incline, it was determined that the hypotheses of The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach., The greater the mass of the ball, the greater velocity the ball will reach., and The more centered the mass of the ball, the greater velocity the ball will reach. were supported. Lane Dederer There are multiple factors affecting the velocity a ball gains while descending an inclined plane. One simple factor that will affect the velocity of a ball rolling down an incline is the angle of the incline. This is due to the fact that when the angle of the incline is increased, the height of the incline also increases. Gravitational potential energy equals mass multiplied by gravity multiplied by height (), meaning height is one of the factors affecting the potential energy the ball possesses. The higher the angle of the incline, the faster the velocity Another factor affecting the velocity of a ball rolling down an incline is the mass of the ball, which is also a factor in the gravitational potential energy equation. The last factor that will be discussed is mass distribution within the ball. The velocity of a ball rolling down an inclined plane could be affected by the location of mass within the ball. For example, if the majority of the mass of a ball is located on one side, this would likely create different results compared to a ball in which mass is distributed evenly. (Hyperphysics.phy-astr.gsu.edu, 2017) While potential energy is determined by the equation of , the actual energy produced (kinetic energy) is also dependent on rotational kinetic energy of the ball, which is represented by the equation . In this equation, and . Â   Â   Gravitational potential energy Gravitational potential energy or GPE is a type of potential energy possessed by an object due to its position in a gravitational field. (Hyperphysics.phy-astr.gsu.edu, 2017) One way to demonstrate this concept is a ball rolling down an incline. When the ball is stationary at the top of a slope, it possesses 100% gravitational energy, meaning none of its potential energy has been converted into another form of energy. When a ball rolls down an incline, its gravitational potential energy is converted into motion, or kinetic energy (KE) which will be discussed next. When the ball has travelled half way down the incline, it possesses 50% GPE and 50% KE. When the ball has travelled 75% of the distance down the incline, it possesses 75% KE and 25% GPE. When the ball has travelled 100% of the distance of the incline, it possesses 100% KE and 0% GPE. This is due to the fact that all of the balls GPE has been used or converted into KE. At this point the ball no longer possesses any potential to be put into motion unless acted on by an external force. Gravitational potential energy can be calculated using the following formula: Which simplified looks like the following: This equation shows that the higher the height of an incline, the more potential energy would be possessed by an object at the top of the incline. The equation also shows that the higher the mass of an object, the more GPE it will possess. While acceleration due to gravity (g) is also a variable in the equation, as the acceleration of an object due to gravity is the same everywhere on earth. (Physicsclassroom.com, 2017) Kinetic energy Kinetic energy is the energy of movement, or motion. It is defined as an object in motion possesses kinetic energy. (Hyperphysics.phy-astr.gsu.edu, 2017) Kinetic energy can be calculated using the following equation: Simplified: The equation for kinetic energy shows that it is dependent on mass and velocity. Therefore, the higher the mass of an object the more kinetic energy it possesses, and the higher the velocity of an object the more kinetic energy it possesses. (Physicsclassroom.com, 2017) Friction Friction is a form of resistance between two solid objects. The amount of resistance between these two solid objects is in most cases dependent on the force holding the surfaces of the two objects together, and the roughness of each surface. The formula for friction is as follows: Where: (Hyperphysics.phy-astr.gsu.edu, 2017), (School-for-champions.com, 2017) The hypotheses for the experiment are as follows: The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach. The greater the mass of the ball, the greater velocity the ball will reach. The more centered the mass of the ball, the greater velocity the ball will reach. Equipment was gathered including a 1 meter long flat wooden board, 4 table tennis balls, a stopwatch, fine sand, water, a drill, adhesive tape, and a stack of textbooks. Firstly, the wooden board was placed one end touching the desk and one end supported by the textbooks, creating the incline that was used for the experiment. An opening was then drilled in 3 of the 4 table tennis balls to allow for insertion of water and sand, allowing balls of varying mass. Once the incline was at the desired angle, the ball being tested was held at the top of the incline. The first participant suspending the ball at the top of the incline gave a countdown, prompting the second participant to start a stopwatch as the ball was released. As soon as the ball reached the bottom of the incline, the stopwatch was stopped. The time provided from the stopwatch was then arranged in a table. This process was repeated three times for each angle in test one (how the angle of incline affects the velocity of a ba ll rolling down an incline), and five times for each angle in test two. (how mass affects the velocity of a ball rolling down an incline) As test one was not testing any variables to do with mass, it only required one ball to be used throughout the test. The sand filled ball was chosen for this as it was solid and consistent. Angle of incline The way the angle of the incline affected the balls velocity was tested by rolling the ball down an incline at angles of 5Â °, 10Â °, 15Â °, 20Â °, 25Â °, 30Â °, 35Â °, 40Â °, and 45Â °. Each of these increments were tested three times, ensuring accurate data. The angle of the incline was calculated using trigonometry, using the height of the incline and the length of the incline (the hypotenuse) to find the required angle. Textbooks were used to support the board at the correct height. Once the correct angle of incline was met, the ball was timed rolling down the incline 3 times for the sake of accurate data. This process was repeated for every angle being tested. Mass of ball The effect the mass of the ball had on velocity was investigated by testing three balls of different masses. One ball had a hole drilled in it and was filled with water (36.2 grams), one ball had a hole drilled in it and was filled with sand (52.4 grams), and one ball was left as it is (2.7 grams). Each of these balls were timed five times rolling down an incline of 20Â °. All data from the experiment was recorded on paper and arranged in a table, so it could then be graphed, allowing the data to be analysed and observed in an organised fashion. As , the velocity the ball reached can be calculated using the time recorded from the experiment, and the distance, which is the length of the incline which was simply measured with a ruler to be 0.91 metres. An example of this for the ball rolling down the 0.91m incline in one second is as follows: Independent, dependent, and controlled variables The independent variables in this experiment include the angle of the incline, the mass of the ball, and the mass distribution of the ball. The dependent variable in this experiment is the velocity of the ball. Controlled variables are variables apart from independent and dependent variables that can still affect the results of an experiment. The controlled variables in this experiment are the surface the ball is rolling on, the material the ball is made of, the size of the ball, the measuring devices being used, the distance the ball travels, and the method being used to release the ball each time, for example the position of the hand. Safety In this experiment safety glasses were worn by participants to prevent any possible damage to the eye. The landing zone where the ball reached the bottom of the ramp was blocked with a stack of textbooks. This choice was made as the ball possessed a reasonable amount of kinetic energy as it came off the incline, meaning it could interfere with other classmates experiments and even become a hazard. (for example knocking a glass beaker off a bench) While these situations are quite unlikely it is good practice to evaluate any possible errors that could occur in an experiment and prevent them from occurring in the first place through proper safety practices. Test 1: How the angle of incline affects the velocity of a ball rolling down an incline. Angle of incline (degrees) Time taken to roll down incline (seconds) Test 1 Test 2 Test 3 Average 5 1.82 1.59 1.68 1.70 10 1.12 1.15 1.04 1.10 15 0.82 0.63 0.81 0.75 20 0.75 0.69 0.63 0.69 25 0.66 0.44 0.59 0.56 30 0.66 0.69 0.47 0.61 35 0.59 0.53 0.63 0.58 40 0.41 0.53 0.47 0.47 45 0.50 0.54 0.47 0.50 By using the equation for velocity ( simplified as ), the above timed results can be converted into velocity. For example, finding the velocity of the ball from test one rolling down an incline of five degrees. This process is then repeated for every single result and put into a table.

With all values substituted in, the equation for energy transformation is as follows: Which provides the velocity of the ball at the bottom of the incline: (Hyperphysics.phy-astr.gsu.edu, 2017) To find the velocity of the ball from this point, the values for g and h are simply substituted into the equation. For example, to find the theoretical velocity for a ball rolling down a ramp that is 10 centimetres high the equation will look like the following: This equation will be used to work out the theoretical velocity for each ramp height. All results can then be put input into a table or graph to observe and compare real results to theoretical results. Angle of incline (degrees) Test 1 Test 2 Test 3 Average velocity (metres per second) Theoretical velocity (metres per second) 5 0.50 0.57 0.54 0.54 1.06 10 0.81 0.79 0.88 0.83 1.50 15 1.11 1.44 1.12 1.21 1.83 20 1.21 1.32 1.44 1.32 2.08 25 1.38 2.07 1.54 1.63 2.31 30 1.38 1.32 1.94 1.49 2.51 35 1.54 1.72 1.44 1.57 2.70 40 2.22 1.72 1.94 1.94 2.85 45 1.82 1.69 1.94 1.82 2.99 The results gathered from this experiment while not following theoretical results, prove to follow projected results relatively closely in the above graph. The comparison between the two sets of data shows that both quite closely follow the same path, however the real data is just lower than the theoretical data. Some possible reasons for this difference include the fact that the equation doesnt account for friction, and the quantity of angular momentum. While the energy lost due to unaccounted for friction in the experiment would be negligible, as acceleration is an exponential value, a small change in the amount of energy in the experiment could noticeably change results quite quickly. The equation used for theoretical data also wasnt accounting for the angular momentum of the ball. Angular momentum is a is a form of stored energy observed in things such as a rolling ball. This means while the ball in the experiment was rolling down the incline, it was storing part of its energy as angular momentum, taking away from the actual kinetic energy of the ball. Both factors combined can create quite a difference in real data compared to theoretical data, which is one explanation for the difference between real and theoretical data. While the results are not perfect, in the angle to velocity graph the real data gets closer to the predicted theoretical value as the experiment goes on. The real results get proportionally closer to projected results even though looking at the real results there appear to be outlying data points bringing down the value for the average velocity of the ball in the second half of the graph. This is proven below. This proportional gap being closed more the further the experiment progresses is thought to be due to the exponential nature of acceleration. First four points of graph: Second four points of graph: By evaluating the results from test 1, it is made clear that the higher the angle of incline, the higher velocity the ball will reach. In case the increase in velocity compared to increase in incline angle is not completely uniform. However the addition of a trend line shows that while there are outlying points lower than expected, the data shows that the velocity of the ball is still increasing as the angle of the incline increases, which supports the hypothesis of The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach. The second test involves four different ping pong balls. One is a regular ball, one filled with water, one filled with sand, and one half filled with sand. The ball half filled with sand will be ignored for now. By evaluating the results from test 2, it is shown that the regular ping pong ball (2.7g) is the slowest of the 3 balls being analysed, with an average velocity of 1.18. The ball filled with water (36.2g) comes in with the next highest velocity with an average of 1.32. Lastly, the ball filled with fine sand (52.4g) reaches the highest average velocity of the three, coming in at 1.42. This data is seen displayed in the mass to velocity graph from test 2 on page 9. By analysing this graph it is made clear that the hypothesis of The greater the mass of the ball, the greater velocity the ball will reach. is supported, as the velocity is clearly seen going up as mass of the ball goes up. The last hypothesis is related to the ping pong ball that was only half filled with sand that was mentioned previously. This ball was made with the intention of analysing the effects the center of mass has on a ball. This ball came in with an average velocity of 0.96, which is by far the lowest average velocity of the four balls. By observing the mass to velocity graph from test 2 it is clearly seen that the ball half filled with sand has a significantly lower velocity than the rest of the balls tested. Therefore, the hypothesis of The more centered the mass of the ball, the greater velocity the ball will reach. Is supported. Using the square root function the results from each set of data can be compared. The equation used to calculate theoretical data can be simplified to the square root function, meaning both equations can represent the same line. This will be demonstrated below. Looking at the graphed results and placing a power trendline on each set of points shows that the above equation relates directly to the equation of the lines in the graph. This comparison is shown below. Looking at the equations for each trendline it can be deduced that they can be represented by the square root function. Throughout the experiment in this investigation there are many aspects that could lead to flawed or inaccurate data. While the data didnt exactly match theoretical data, it quite closely followed the predictable nature of a power trendline. The results that stray the most from the trendline are the results from the second half of the angle of incline test, between 30 and 45 degrees. These seemingly anomalous results are most likely due to the measurements for the experiment being recorded by humans. The times for the experiment were recorded by a participant using a stopwatch, meaning there are multiple points throughout a single run of the experiment that could lead to inaccurate results. The first is the ball being released. One participant held the ball at the top of the incline, and with a countdown would release the ball, prompting the second participant to start the stopwatch. This part of the experiment alone can create slightly inaccurate data, as the participant starting the stopwatch is reacting to the visual que of the ball being released and the audio que of a countdown. According to backyardbrains.com, the average human reaction time to a visual stimulus is 0.25 seconds, and 0.17 seconds for audio stimulus. As both of these are involve
