Advertisements are a Waste of Resources

In a competitive economy, companies seek to persuade consumers to buy their products or to avail their services. It is impractical to think that companies should only stock their warehouses and wait for consumers to come knocking on their doors. If this is what businesses did, there would be an economic waste in terms of products being produced but not being bought.The critics of advertising attack the form of competition it provokes by saying it results in duplication and waste. It is equivalent to an arms race in the sense that a certain pattern might exist within an industry or sector concerning the extent of advertising. So if one competitor increases the extent to which it advertisers, others feel it is necessary that they do the same or at the very least engage in some form of advertising in order to maintain its market share or face the prospect of losing it.The advertisement rates during the Indian Premier League (IPL) season 6 might be an example to some advocates who believ e advertising is a waste of resources. In this case, the resource alluded to is money. A ten-second advertisement spot cost between Rs 4-4.5 lakhs, while the associate sponsors of the event PepsiCo and Vodafone shelled something between Rs 40-60 crores each.These are nothing short of extortionate rates but companies must be having evidence to show that such rates are justified. It should however make marketers ask themselves an important question. Should they spend money on making a brand promise through advertising, or should they focus on keeping their brand promise by means of delivering what consumers want. However, although competition in advertising involves such waste, it is also a driver of innovation and setting new benchmarks. Competition is vital as it far outweighs its negatives with its positives and is a necessary requisite of a successful economy.There are some companies that literally manage to survive by spending almost nothing on advertising. Zara uses this strateg y and does it by employing a strong in-store experience and keeping their shelves stocked with the latest fashion through quick production methods. One might say Zara is more focused on keeping their brand promise. Marketers would agree that advertisements should not be made simply to create a buzz, but to help in the generation of sales.An important point to consider is the brand life cycle, as the role played by advertising depends on it. A new brand may find advertising a very important function so as to target potential consumers. At this stage, brand recognition is critical and advertising is the only way to build it when there are new products or services to offer. A mature brand on the other hand might want to further its reach through advertising or may even be trying to bounce back from a recent decline in sales.But is advertising a waste of resources? To answer this question, it must be kept in mind that advertising doesn’t exist in a vacuum.It has to be considered as one of the alternatives available in the marketing of products and services.The decision doesn’t lie at the extreme end of whether to advertise or do nothing, but is rather to either engage in advertising or in some other form of sales effort. It is one part of the marketing effort which includes packaging, servicing, direct selling, pricing and is generally undertaken when it can justify being the most effective and economical method to appeal to customers.It is a vital function if you consider its reach and ability to communicate with all potential customers and is therefore used widely by many companies. If a company decides to substitute advertising with another method that might prove to be less efficient, it would result in economic waste. The use of resources for advertising to differentiate products from competitors would not always mean that its use has been diverted. On the other hand and quite frequently, it denotes the use of resources that would otherwise be i dle and thus avoids the waste that comes with such idleness.

Helping People in Need a Supererogation or an Obligation

Helping people in need a supererogation or an obligation People in poor nations are starving to death when we are enjoying our delicious meal with our friends and family. There are various governmental aid-projects and privately run charities which are responsible for delivering donations from the relatively wealthy nations to the nations in need. I believe it is a morally right thing to help the people in need, but not every one of us would make donations regularly.Peter Singer uses the drowning child example to make people rethink about this current scenario. He believes that it is our obligation to help the people in poor developing countries. There are objections to his stance, but before considering and discussing from both sides, I am now going to describe and explain the Singer's drowning child example first. Imagine a child is drowning in a shallow pond and saving the child’s life means jumping into the pond and thereby getting one’s clothes wet and muddy. Would you still save the child?All of those having a rational mind will say yes. In spite of the bad consequence of fouling the clothes, saving the child’s life is morally what we ought to do as the importance of the child’s life so far outweighs the little cost of getting one’s clothes wet and muddy. It is within our power to prevent the child’s death without sacrificing something that is of even greater importance. Thus, this is what we ought to do and it is our obligation to prevent something this bad from happening (Singer, 1997).Even when there are other people near the pond who are equally qualified of saving the child but are doing nothing but simply passing by, would you still jump in and save the child? Similarly, all of those being asked said yes. It simply does not make any moral difference to the situation. Undoubtedly, not saving the child in this situation might make one feeling less guilty but everyone thinks that we ought to save the child. We agree that this is our moral obligation and it would be wrong not doing so (Singer, 1997). Then what if the child were being far away, maybe even in another country?Would people still hold the same stance? The answer is yes. Distance and nationality do not make not saving the child just. Whichever child or even adult, if saving his life is what we are able to do without having something of great significance to us being sacrifice, we ought to do that. This is morally what we ought to do without violating other things that are of similar or higher moral importance (Singer, 1972). The situation of the drowning child example is actually synonymous with those hungry children and adults suffering from famine or other disasters, both natural or man-made.If we agree that saving the child that are drowning in a pond is morally what we ought to do and not doing so is unjust, then why should we think otherwise when it comes to helping the people who are suffering in poor developing countries? Why does making regular donations to nations in need not our moral obligation whereas saving the child drowning in a pond is? We have agreed that distance and nationality does not matter in this moral stance. Moreover, the problem of being too far away from the sufferers and we might not be able to come to their aid in time has been overcome by the effort of charities.What is it that stop us from making regular donations? There are explanations to this bipolar situation, giving reasons to help better understanding the causes leading to this global scenario. First of all, saving the drowning child is helping out directly, while making a donation is not. The donation will be distributed to the people in need through the government or some privately run charities. Some of the donation will be used for administrative cost or get swallowed up in corruption.People will never know how much of their donation can really be given to those in need. As corruption is usually a prevalent problem in many of the developing countries, people sometimes have the worry that their donation might not serve to their right purposes but only be ended up in greedy hands. This worry is reasonable but actually most of the donations can get to serve their proper purposes (Giving What We Can, 2012). Although not all of the sum can be used for aid, the part of it that gets to its destination still can make the best of its worth.The aid organizations may not be one-hundred percent efficient, but they can help to solve the problem of distance, serving as an agent for delivery. There are many people around the world who are compassionate about the plight of the others. Charities and governmental organizations collect the aids and help distributing them to the areas in need. I think this is by far the most efficient way of giving out a helping hand. The cost for administration is inevitable and the part of donations spent on it could be seen as for supporting these organizations to keep runnin g.Furthermore, in my point of view, there are always ways to minimize corruption. We can donate money to aid projects that do not involve valuable goods or specifically make donations to programs which serves to tackle the corruption problem in where it is prevailing. The probability of wasting a proportion of the donations should not mean aiding being useless. Those that can get though may make a significant change that we could not imagine. The second explanation is about the psychological difference between the drowning child example and the reality.We feel more related to the sufferers when we could see them. The feeling of guilt for not helping is lesser when we could not see or witness the sufferings (Singer, 1972). Although it makes one feels less guilty without the sight of suffering presenting nearby, it does not make helping those further away a lower priority morally. As we have discussed that distance is not a considering factor in deciding whether it is our obligation t o help or not, both of those from our own country and from the other countries deserve our help.Moreover, in this age of the prosperous development of media technology, charities and governmental aid agencies can effectively show the current situation of the emaciated children to the public. Therefore, it does not sound very plausible to me saying that people not making donations is because of the lack of awareness of the issue. According to Peter Singer, a moral philosopher, if we are able to prevent something very bad from happening, without thereby sacrificing anything morally significant, we ought, morally, to do it (Singer, 1972).Some people object this position. I am going to summarize those objections. For one of the reasons is that this is simply too extreme as most people do not judge those who are ignorant of the others' suffering. People usually criticize those who violate some moral norms, for example: murdering, sex assault,etc. Some writers, including Sidgwick and Urms on, Stated that if the moral code that we set is too hard too uphold, there will be a general breakdown in the moral system (Singer, 1972).The moral code that we are currently using mainly includes not invading the others' privileges, for example: stealing, killing, etc and other things that could help keeping the society safe and sound. Helping the poor nations is not necessary for the wealthy nations. Thus, people usually do not see it as what they must do. This is regrettable but understandable. If making regular donations to those in need is being made to be an obligation and a moral code, it might be too hard for everyone to follow. Eventually, people might choose not to follow anything from the moral code (Singer, 1972).Singer argues that if the conduct is good, why should we categorize it into morally obligatory or morally optional? If morality means doing something good, then shouldn't a good conduct be in the moral code? Moreover, drawing a line to divide conducts into the aforementioned categories is by no means easy. It is hard to define the standard to be used for distinguishing conducts into two kinds. Helping the people in need in other countries is always be defined as a generous and selfless gesture. However, Singer thinks otherwise. He thinks that â€Å"our traditional moral categories are upset†.He objects the traditional distinction that is drawn between duty and charity by using the current standard. It is our moral obligation to prevent as much sufferings as possible in the meantime not sacrificing something else of comparable moral importance (Singer, 1972). How does a man act is actually influenced by the general societal values and the people around him. When a man making a donation or joining voluntary services to help those in need is being praised for his generosity, he would think that what he has done is a supererogation.Actually, coming to the others' aid to prevent suffering without sacrificing as much is an obligation tha t people usually overlook. This situation is for long being shaped by the general social atmosphere and this is what being upsetting. The moral attitude of people is shaped by each other and also the society. Admittedly, helping those is need is always greatly encouraged. However, this is by no means enough. Preventing as much sufferings as possible without causing sacrifices as significant is morally obligatory and not doing so should be seen as unjust (Singer, 1972).I agree with Singer that if it is within one's ability to help, saving other people from suffering seems to be just and morally right, while otherwise seems wrong. Although there might be concerns that what we have given might not be able to serve their greatest worth, I believe that the part of aids that get to the hands of those in need is able to make a significant change in their lives. There are worries that helping those poor developing countries might worsen the current situation. Firstly, those countries usuall y have a higher birth-rate.The aids that we give now would only support them to have a even greater population that the countries themselves are not able to feed (Giving What We Can, 2012). This might leads to a greater demand in foreign help and eventually turns into an ever-expanding cycle. This worry is understandable but there are always other alternatives to help in this kind of situation. For fear of the problem of overpopulation, donations could be made to organizations that help in promoting and enhancing birth-control in the developing countries.Moreover, the reason behind the scene of them having a high birth-rate is the high mortality rate of children. They need a large family size to ensure having enough manpower to take care of the family, to work and to earn. If their lives were not this hard, the birth-rate would presumably decline (Giving What We Can, 2012). The other worry is that the developing countries might become more and more dependent on the aids (Giving What We Can, 2012). This worry is again not necessary as there are many aid projects that are actually aiming at helping those developing nations to be self-supportive.People in some of the poor nations are taught to grow crops for supporting themselves and for selling to make money. Donations could be made to support this kind of projects. Moreover, helping those in need does not necessarily means lengthening their life expectancy but might be about improving their living quality (Giving What We Can, 2012). One example is performing a simple eye operation to cure their eye diseases so that they could see the world more clearly. It is our obligation to help the others in need when it is within our own power without sacrificing something of higher importance.Death and sufferings are things that should be prevented. This is what we ought to do. With the gap between the rich and the poor growing everyday, our moral attitude towards giving out aids should be revised. Helping should not be s een as a supererogation but an moral obligation. References: Giving What We Can. (2012).

Effect of Ocean acidification upon ability to genetically adapt in Essay

Effect of Ocean acidification upon ability to genetically adapt in Nereis species - Essay Example This change affects the small marine organisms the most. The decrease in pH affects their physiological processes mainly their metabolic rates and oxygen intake processes. Calcifying species are also affected due to the decrease in CO32- ions, which are used in forming CaCO3. Due to these effects, the species have to adapt to these changes in order to counter the negative effects on their physiology. These changes may be phenotypic for short term or genotypic for long term. This paper investigates the effect of ocean acidity on the genetic makeup of the Nereis species (Australian Biological Resources Study, 2000, p.45). Due to the increase in the ocean water acidity, the marine species have adapted to the change in pH. All the specimens have the same gene expression alterations when exposed to low pH. All the species experience phenotype plasticity when exposed to low pH levels. These effects can be determined by scientific methods. Species from the low pH region of Ischia have adapted to low pH (Armstrong, A. 2013, p593). Six marine species were picked for the research namely; Polychaetes, Nerissuccinea, Nereisdiversicolor, Nereisvirens, Platyneiresdemerilli and Nereiszonata. The worms were collected from different areas. Some samples were from Ischia region, a place with low pH value due to CO2 vents. These samples were exposed to low pH value environments for short time and long-term durations. The control group was set in normal pH environment. The pH value affects energy production processes in the specimens. With differences in pH, the individuals of the Nereis genus undergo some changes in energy production. The samples from the regions of low pH show the least changes, having adapted to low pH levels. All the specimens are affected by extremely low pH levels but the specimens from the vents show the most resilience since they have already adapted to low pH environs. This is because their metabolic activity is always heightened. The responses

Finding Darwin's God Assignment Example | Topics and Well Written Essays - 750 words

Finding Darwin's God - Assignment Example Miller holds the point that thought scientist might explain their understanding of the Universe in terms of the quantum physics theories; however, every theory has its influence from the supreme creator called God.   Quantum theory of physics observes the Universe as a combination of smallest or discreet parts such as atoms, nuclei, and subnuclear parts. Miller observes that these discreet particles, when combined in a random fashion, might have chances to result in unpredictable happenings in the world. In other words, the microscopic particles identified by quantum physics would combine to end up in macroscopic events; this unpredictability, Miller calls as the central property of matter. On the other hand, God, who created innumerable things in the same way as the combination of discreet particles influence the world with unpredictable events. Miller’s argument tries to build strong logical compatibility between the quantum theory, the evolution made by God, in terms of u npredictability, Miller seems to have maintained an acceptable logical statement that science and religion have unpredictable things in common. This could be understood in with the help of many events, which has happened in the course of years. If the scientists could consider the first report of Tsunami, Katherina and various tremors occurrences as unpredictable, then the same could also be argued in terms of some supernatural influence holding the earth. In this sense, Miller wins his argument.  Miller observes that creationists have the belief that natural science ends up with supernatural conclusions, but he differentiates religion and natural science clearly. There exists meaning for everything made by God and hence his creation holds his identity, so there is nothing-logical present in evolution and thus they believe that there is God argues creationists whereas evolutionists argue that there is logical reasoning for everything in the world.

Journal 8 - Essay Example At the ball, she encounters the prince, and this really lifts her mood. However, her joy is short-lived as she leaves the ball bearing in mind she may never see the prince again, but he searches for her using her glass slipper and finally finds her. They live happily ever after. The protagonist in the story is Cinderella who is saddened by the fact that she cannot go to the ball; this is her preliminary state. The Fairy Godmother avails all that Cinderella needs to go, but she also brings in disequilibrium by requiring that she returns before midnight. At the ball, Cinderella’s state of mind is varied and she grows happy when she meets the prince (286). Once again, she is crestfallen because she does not expect to see him again. Disequilibrium occurs when the prince uses her slipper to find her, and it appears that Cinderella might be happy once more. When he does find her, they live together in happiness, which is the ultimate state of mind. The story goes a long way in revealing the culture of those from who it comes. In this case, the story shows that women who are industrious and altruistic are compensated with riches and great joy. In addition, love is the foundation of any relationship and that getting married because of love leads to eternal

Research essay Example | Topics and Well Written Essays - 1000 words

Research - Essay Example Indeed, the humors lie in the verbal ironies in the story. At the very beginning of the story, the readers learn about the revenge motif of Montressor (Silverman 312). So, when, in the story, they come across the verbal ironies in Montressor’s narration, they rather become aware of the follies, simplicity and hubris, of Fortunato, which inevitably push him towards the horrible death. Also the humors in the story are endowed with a two-fold meaning. On one hand, they provide brutal pleasure to Montressor; on the other hand, they reveal Fortunato’s follies and hubris. Montressor exhibits a black sense of humor. In the very beginning of the story, Montressor describes Fortunato in a jester’s outfit. He describes Fortunato as following: â€Å"[In] one evening during the supreme madness of the carnival season, that I encountered my friend†¦.The man wore motley† (Poe pars.2). In that carnival evening, Fortunato wear a â€Å"tight-fitting parti-striped dres s† (Poe pars.2). He also wears a â€Å"canonical cap and bells† (Poe pars.3). ... But when Montressor vows that â€Å"I must not only punish but punish with impunity. A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong† (Poe pars.3), Fortunato’s jester-like clothing and hubris make him more vulnerable and pathetic. Another humor occurs around the middle of the story. When Montressor and Fortunato enter into the cavern, he (Fortunato) begins to cough. In order to hide his intention, Montressor tries to persuade Fortunato to go back: â€Å"We will go back; your health is precious. You are rich, respected, admired, beloved; you are happy, as once I was. You are a man to be missed. For me it is no matter. We will go back† (Poe pars.6). In reply, Fortunato says, â€Å"Enough†¦the cough's a mere nothing; it will not kill me. I shall not die of a cough.† (Poe pars.8) Here though his reply evokes laughter, it, at the sam e time, warns the readers about his helplessness in the face of Montressor conspiracy. Fortunato, a helpless drunkard who does not know the least of Montressor’s revenge, expresses habitual hubris that he will not die of coughing. This scene makes Montressor more pernicious and venomous, whereas this same reply exposes Fortunato more as a helpless man who simply believes Montressor and who is going to face his death soon (Silverman 312). At the second reading of the story, the perception that Fortunato is going to be buried alive behind the vault wall reveals the darkness and blackness of Montressor’s sense of humor. The blackest humorous scene occurs around the end of the story. Here, Fortunato starts to laugh after

Computer Professional Ethics Journal #2 & #3 Essay

Computer Professional Ethics Journal #2 & #3 - Essay Example With such inevitability, there is a need to make precautionary measures to counter forces that are bound to "steal" their "intellectual rights". In the United States, there has been a growing problem in appellate courts particularly in patentability of computer programs where they have been struggling with the subject matter requirement for patentability. The courts have been having trouble deciding whether various types of software can be accurately characterized as falling under any of the areas of patentable subject matter such as "processes" or "machines". During the early 70s, this has been the problem in the case of Gottschalk v. Benson, where the Court framed the issue as "The question is whether the method described and claimed is a process within the meaning of the Patent Act." As the years progressed, problems in patentability became more critical and complex. From the definition of "process", issues in patentability also delved into software originality, novelty, piracy, p rotection, and even at face value "stealing" (by pirating or recruiting the computer scientists from another company). And because of this, computer scientists must be well aware of these facts so that they could create counter measures such as security programs, password protections, and other suitable alternative

The relationship between space and time in language Essay

The relationship between space and time in language - Essay Example We suggest that there is no direct interdependency between these terms, because they are defined by exact contextual environments and are clearly differentiated from one another in the natural environments. On the basis of modern studies and studies on temporal and spatial representations of previous years, we have examined linguistic basis to prove the fact of a co-existence of spatial and temporal relationships. Moreover, considerations from cognitive science, psycholinguistics and neurolinguistics are also relevant to further differentiation between spatial and temporal relationships. The spatial basis of temporal terms has been often supported by the majority of scientists and researchers (Cantor & Thomas, 2007; Clark, 1994; Levinson, 2003). This study opposes to the generally accepted methodological paradigm and it is claimed that there spatial/temporal terms chosen above are independent terms with complete semantics. Moreover, there is no need to investigate a temporal or spati al basis of these terms, because initially spatial domain is perceived as concrete and temporal domain is known as the abstract one. Therefore, we can suppose that â€Å"terms denoting space are concrete objects and the terms denoting time are abstract events† (Tenbrink, 2006). ... nt to investigate a possibility to identify definite limits between time and spatial relationships or it is relevant to talk about the existence and prevalence of spatiotemporal relationship. 2.0 Background Basing on the idea that human perception of time is related to space conceptualization is an unquestionable claim. It has been always underlined that time representation depends on space. In accordance with findings of psychological studies, it has been always claimed that it is natural of children to mix up spatial and temporal relationship (Clark, 1994). Clark (1994) was the first who claimed that â€Å"temporal language is based on spatial language and that English relational temporal prepositions are based on front and back† (Clark, 1994). Clark talked about â€Å"moving time† metaphor and â€Å"moving ego† metaphor and underlined that, for example, before is derived from in front of and after is derived from in back of, i.e. he correlates these two terms with â€Å"moving time† metaphor (Clark, 1994). Nevertheless, it is worth remembering that there is no one basic conceptual metaphor defining further metaphorical representations of a certain domain. A consistent basis of a metaphor has been often underlined by Lakoff and Johnson (1999). Therefore, it is necessary to underline that representations of concepts in metaphorical language is also possible outside this language, or in other words is possible in an independent manner. Still, there is a need to talk about the following peculiarities of metaphorical representations: metaphors are compatible with different domains though they do not have a scope covering different aspects of one domain and thus do not embrace the whole target concept. From another perspective, it is suggested by Habel & Eschenbach (1997)

Theme park report Assignment Example | Topics and Well Written Essays - 2500 words

Theme park report - Assignment Example Major reasons identified in the research are – world economic crisis, stiff local competition, low level of differentiation of services and negative image of the company regarding safety standards and bankruptcy filing. A discussion of possible solutions followed by recommendations concludes the paper. The major recommendation is to restructure the organization to enable a flatter structure for faster decision making and more employee empowerment. Introduction Theme park industry has evolved immensely over time. With a handful of theme parks concentrated within US during the beginning of the 19th century, the industry has grown tremendously. US itself has 600 entertainment parks and attractions as per recent studies while Europe houses 300 of them (Woodside and Martin 2007). The industry is cyclical and is heavily dependent on weather conditions. For example, in US, 46% of the people prefer going to theme parks during summers, 21% prefer spring while 18% prefer autumn season ( Woodside and Martin 2007). ... The company has exclusive rights to sell products bearing these characters as well as use them for advertising and promoting the â€Å"Six Flags† brand (Six Flags Annual report 2010). The theme park has been through turbulent times and had to file for bankruptcy because of the decline in visitors across its various sites. Three main reasons for this situation are as follows: Deterioration of the US and European economies (yahoo.brand.edgar-online) Excessive competition from other entertainment avenues during financial crisis years Lack of differentiation from other competitor in entertainment experience provided to the customers The company needs to formulate a strategy that can help it overcome all the above difficulties. A reduction in entry fee or overall cost of entertainment, focusing on tie ups with other entertainers to reduce competition and encouraging innovation in services within the organization culture can be some of the solutions. We will discuss each of these is sues and their solutions in greater detail in our ensuing sections. Methodology A research paper is incomplete without a mention of the methods employed to analyze and conclude a paper. Research involves data collection, its analysis and finally reaching a conclusion. Methodology helps in defining the research design, the way data is collected, the validity of the data and the limitations of the research. Two types of data have been used in the research – primary and secondary. Data directly gathered from the company is the primary data. Secondary data is the one used from other researcher’s analyses. Most of the data used in the ensuing paper is the secondary data from books and journals and

HIV in Humanitarian Contexts Essay Example | Topics and Well Written Essays - 2500 words

HIV in Humanitarian Contexts - Essay Example The outcome is the need to stop HIV and to assist those which are a threat to the health of others continues to increase while PLHIV treatments are in need of reaching larger groups of individuals (Smith, 2010). The need to approach this issue is one which is based on responding to emergency situations as well as considering the growing numbers of individuals who are in need of treatment that have PLHIV. The needs to assist those who have PLHIV are continuing to increase not only from the responses which are required to emergency situations or the spread of the disease in specific regions because of the lack of resources. It is also noted that there are humanitarian needs associated with various regions. The concept of humanitarian responses is one which is associated with responding to vulnerable groups and ensuring that resilience can be built in situations because of the services provided. The humanitarianism which is provided first takes place in emergency situations in which an outbreak or other problem arises. There are also some specific concepts which are linked to assisting vulnerable groups because of culture, available resources and service provisions which combine with food, education and sanitation methods (Okal, Bergmann, 2007). Examining the humanitarian methods and designs, gaps that are associated with the needs in various communities and the way in which these can be reconsidered develops a stronger understanding of what is needed to assist those suffering from PLHIV. This research study will examine the current status of humanitarian efforts, how this is creating changes or gaps in providing assistance for PLHIV as well as how different designs can create stronger responses to those who are suffering from PLHIV. By examining these various associations with humanitarian responses, there will be the ability to identify the gaps in assisting those with PLHIV as well as understanding how designs can be changed to assist communities in need of hum anitarian assistance. Methodology The methodology that will be used will consist of two main studies that will define the needs for those suffering from PLHIV and the humanitarian responses that are required. The first is a review of existing literature. This will examine various statistics from specific organizations which have designs and methods for assisting those who have PLHIV. This will also consist of other pertinent literature that is based on the current understanding of how to respond to outbreaks and what this means to those who are in specific settings. The research methodology will be combined with communication through questionnaires. This will be sent to offices in various regions around the globe. The objective of these questionnaires will be to look at the designs which are currently used to respond to PLHIV in various regions as well as what the strengths and weaknesses of the design are. By examining these various types of responses, conclusions can be drawn whic h relate to the gaps in designs which are used to respond to the needs of PLHIV in a humanitarian context. Special Needs of PLHIV in Humanitarian Contexts The first concept which is associated with PLHIV in human context is based on the vulnerabilities which are established in responding to specific needs. The risk for HIV is known to be a main factor in specific areas that lack infrastructure

The Cuban Missile Crisis Essay Example for Free

The Cuban Missile Crisis Essay Histories were once realities. Most of the stories we read in our textbooks for academic purposes were actual real life experiences of some people – people who at that time were faced with fear, anxiety and the pressure to make the right decision. Where we are as a nation today is a reflection of the right or wrong decision made by our leaders. Although we can boast of several illustrious leaders whose decision has helped mould the future of this nation, John F. Kennedy was a president whose choice at a critical period in the history of America made the whole difference (White, 1996). Through his decision, he showed the world that the best way of resolving differences is not through warfare but through negotiations and compromise (Graham, 1999). The true test of a leader is evident in his/she ability to make sound and timely decisions when called upon to do so. A good leader must have the ability to respond to issues, the guts to take risks and foresight to predict what might eventually occur as a result of the decision he/she is making. Where we are as a country today, is as a result of the decisions our leaders have made in the past. No event can be isolated in life; rather, we trace the history of every occurrence to what has happened in the past. This is because the present is a victim of the past and we must understand the past in order to make sense of what is happening in the present. Such is the case in our country. October 1962 – a year that will be marked on the calendar of America. For us who read or heard of the story, it was an historic period in America. However, for those witnessed as the events occurred, it was a period of panic, uncertainty and unrest. Nobody could predict what will happen – not the American government, not the Soviet Union and definitely not the citizens of America. As Allison puts it, the thirteen days that the crisis lasted can be described as the most dangerous moment in human history (Graham, 1999). Sometimes after the crisis, Nikita Khrushchev recalls, I found myself in the difficult position of having to decide on a course of action which would answer the American threat but which would also avoid war.   Any fool can start a war, and once hes done so, even the wisest of men are helpless to stop it especially if it’s a nuclear war. (Gribkov Smith, 1986). The expiration of the World War II brought with it the advancement of science and technology. During the war itself, the German atomic scientists were encouraged o build nuclear ballistic weapons that was capable of destroying a whole city. Scientists from Britain, France, the Soviet Union, and the United States came together in a bid to build a nuclear weapon. This was done under the code-name â€Å"Manhattan Project†. The project was sponsored by America and in July 1945, the first atomic bomb was made. Hiding under the guise of being ambushed during the World War II, America decided to continue the making of nuclear weapons and each one that was made was more dangerous than the previous. However, as it would appear, it was not only the American government that was amassing nuclear weapon, the Soviet Union was also producing nuclear bombs – although not as dangerous or powerful as the ones produced by America. In the scheme of things then, possession of nuclear power automatically makes you a threat to the world and untouchable to other nations. It was a guarantee for safety and it comes with such benefits of being regarded as a world power. America, by inference, was quickly becoming a force to reckon with and a predominant power in the world. The Cuban Missile Crisis itself was an accumulation of the friction between the American government and the revolutionary government of Fidel Castro. Before the Cuban Revolution of 1959, America enjoyed a great deal of influence on the economy and politics of Cuba (Encarta, 2008). However, this changed under the government of Fidel Castro. Castro refused to be influenced by America instead he formulated policies that gave the American government a reason to be concerned. He seized the property of wealthy Cubans and those of foreigners, who were mostly Americans, in a bid to establish a communist system in Cuba. This resulted in the placement of an economic embargo on Cuba. This cut any form of trade between America and Cuba. Instead of giving in, Castro decided to establish a better relationship with the communist nations. During this period, there was a cold war between the American government and the USSR – a war between communists and capitalist nations. In an attempt to overthrow Castro’s government, the American government decided to establish relations with Cubans that were against Castro’s government. The American government trained and supplied ammunitions to anti-Castro Cubans that sought refuge in America. In 1961, these anti-Castro agitators invaded Cuba in the Bay of Pigs. This invasion was not successful and as it turned out, it consolidated Castro’s government. Cubans were infuriated with the U.S government because of its interference with political issues in Cuba and as a result gave their full allegiance to Fidel Castro’s communist government. With Fidel Castro formal declaration that Cuba was a communist nation, the tension between the American government and Fidel Castro intensified. At the same time, Soviet prime minister, Nikita Khrushchev began a plot to secretly deliver nuclear weapons to Cuba. This plan was welcomed by Fidel Castro who wants to use the opportunity to protect his island following the threat of the Bay of Pigs. The Soviet premier devised this plan in order to avert any attack that might be launched against the Soviet Union. This plan was meant to be privy to the United States government. Khrushchev did this on the assumption that this action would go unnoticed by the American government. With both parties fighting a common enemy, an arrangement was made for the quick installation of missiles in Cuba without drawing attention of the United States government. Looking at the crisis from the perspective of the United States government, the crisis began on October 15, 1962 after a U-2 spy plane and U.S. Navy low-level reconnaissance aircraft took photographs of Soviet missiles which was under construction in Cuba. The following morning, the matter was brought to the notice of President John F. Kennedy who immediately formed the EX-COMM. This group consisted of the twelve advisory members who were considered the most competent in handling the issue. President John F. Kennedy decided that the EX-COMM meetings should be held secretly so as not to make the Soviet Union suspect that the United States was fully aware of the situation. After seven days of difficult and long secret meetings, President John F. Kennedy openly announced the discovery of the missile installation 90 miles aware from the shores of Florida. Although President John F. Kennedy was presented with evidence based information that posed a threat on major cities like New York, Chicago and Los Angeles, he knew the situation was a complex one which called for a tactical solution. He was faced with a situation with potentially severe consequences. However, he could not decide the course of action to be taken against Cuba or the Soviet Union. Although America in 1962 can be said to be the predominant world nuclear power, Kennedy and his advisors knew that launching an attack could turn into a nuclear war that could turn into another World War. On the other hand, the Soviet Union posed a threat if America folds its arms and does nothing (Encarta, 2008). The predicament, as Kennedy conceived it, was severe. After several sessions of hot deliberation, President John F. Kennedy and his advisers came to a concession that a blockade would be the right course of action to take. Although they did not all have the same reasons for supporting the blockade, they agreed to the fact that a full military invasion would be risky given the situation of things. On October 22, 1962, President John F. Kennedy openly announced that the Soviet Union should get rid of all the missile bases and their harmful contents. He also ordered a â€Å"naval quarantine (blockade) of Cuba in order to prevent Russian ships from bringing additional missiles and construction materials to the island† (hpol.org, 1990). For several days, the world watched in fear as the crisis intensified. The American government waited for the course of action to be taken by the soviet premier. This is because a blockade, in military terms, was considered an art of war. Although President John F. Kennedy claimed the action was a naval quarantine, Kennedy and his advisers were not certain of how the Soviet Union will conceive of such action (Encarta, 2008). During this period, several soviet ships turned back to from the quarantine line but the missile installation continued. However, on October 26, 1962, the crisis took a new turn with Khrushchev sending a coded cable to Kennedy, offering to withdraw the missiles from Cuba on the condition that United States would not attack the Island of Cuba. Early the next day, President John F. Kennedy agreed to the terms of Khrushchev.

Procurement Strategies: Advantages and Disadvantages

Procurement Strategies: Advantages and Disadvantages The Janus plc is a dynamic retail and leisure group in UK. The Janus group are constantly investing in their ventures and develop several proposals with considerable facilities to expand their group forward. In UK the Janus group already consists of two other proposals which are in operation. As a part of their plans the organisation has decided to make new development proposal at malchester. The organisation is planning to develop the new proposal in two phases. This report is an assessment of the procurement strategies and options for selecting the procurement strategies for design and construction of the new proposal at malchester. The study on the procurement methods and strategies in this report tell us how to process the planning of the project to achieve value for time, cost, quality and helps the clients organization business to move forward. The report also suggests the best suitable strategy with effective implementation offers on time delivery, cost effective, specific quality and makes sustainable delivery of the project. As the selection of procurement makes the work easier to the client in making the project successful and achieving the goals of the organization. It also makes the right decisions for avoiding the risks. So the selection of procurement method plays very important role in constructions. At last the report recommends and justifies the selected potential procurement method for design and construction process with proper guidelines for delivering the efficient project and also to meet the standard quality for service in attaining maximum profit which will move the organizations business forward. Introduction: Procurement is also called as sourcing, which means gathering services and goods from the preparation and of request through the approval of statement for payment. This involves purchase planning, financing, making the purchase, inventory control and stores, specific development, standard determination, supplier research and selection, supply contract administration, disposal and other related functions, value analysis and price negotiation. Procurement plays major role in work relationship between parties involved in the construction process. Identify the primary and secondary objectives of the projects, Risk innate in the proposal, Environmental determination, which it will be implemented and selecting the appropriate procuring method for the proposed project. Procurement was not about a building, it was about entire project which includes obtaining goods and services, also includes obtaining human recourses like, consultants, contractors, sub-contractors, suppliers and specialists for some purpose. It is the very important step which can show some significant impact on the project success. Critical analysis: Janus leisure plc is leisure group which seeking to move its business forward. Janus leisure present operations having six racecourses which stage 20% of all racing fixtures held each year. Which makes them one of the UKs largest of horseracing. It also includes one of the oldest classic races in the world, the 5000 guineas stakes and also some high profile race meetings throughout the year. Conferencing and banqueting facilities will be provided at all of Janus racecourses and making then capable to operate 365 days. Janus leisure offering 18 hole golf courses at two of their racecourses. One includes leisure club and an integrated, branded hotel at third racecourses. Now Janus proposing some improvements to their racecourses, which was hosting 5000 guineas stakes every year in malchester. The redevelopment consists of two phases. Client requirements: Phase 1 Demolition of existing grandstand. Construction of new 5-storey grand stand to include an extensive conference and exhibition centre and associated external works (Budget  £25m). Refurbishment of two existing stand circa 100 years old (Budget  £5m). N.B to enable redevelopment during phase-1, the 2011 guineas stakes meeting and the 2012 5000 guineas stakes, schedule for mid-September must return to malchester. Phase 2 Construction of a new 120-bed hotel facility and casino (Budget  £12m) to be operational for the 2013 5000 guineas stakes meeting in mid-September. As Janus Leisure Company mentioned that they require finishing phase-1 by mid September 2012 for 5000 guineas stakes and phase-2 by mid-September 2013 for 5000 guineas stakes. As the company is trying to develop all their venues they will be having less concentration on a single venue and also the client knows what they required and what they expecting from the contractor. This project also includes demolition of existing grand stand and refurbishment of two existing stands. Which means it includes mixture of different kind of construction process. The main things in this project were time completion and budget. Completing the project in budget and maintaining the quality of construction. Clients have different needs and it is necessary to ensure satisfactory results to the development process by the contractor. There are some procurement methods which meets our clients requirement. The main factors when considering the appropriate procurement method: Project size Budget Complexity of project Time Probability of change in design and construction phases Quality importance Ability of contractors to undertake the project (Organisation) Design In this project we decided to go with Design and built type of procurement method which was suitable for this type of client. Our client needs racecourses by the 5000 stakes time, so its necessary for the contractor to complete the project by the time without delay. Price certainty: The certainty of price for the total construction work period. Price certainty will change at the time of process of project. Getting the firm prices before the construction of the project, this enables approximate estimates for the client. The cost of the project will be within financial budget. Public employers consider less important in price certainty. And they focus on quality and the functionality of the work done. For private client it is important to control their financial budget by obtaining the price certainty. Dead line: The majority of clients will make the decision and want to complete the project as quick as possible. Here our client need our project in time to extent and start his business soon in malchester. Time availability also influences the project to choose the construction techniques. The implication is under some circumstances such as time, cost and quality. Design: Design and build is the only method which likes into account Buildability, and produces a design in terms of construction. Traditional procurement method of contract was failed id design aspects. Some management contracting type of procurement processes have a grip on the design. If the client was been approaching a single contractor for a long time, it was beneficial to the clients. The main design factors considered are: Function Maintenance Buildability Standard design Design before build Design prototypes Procurement methods: There are several ways to categorised procurement methods. Risk taken by each party Information availability at the time of distributing contracts. The way of design and construction is ordered and maintained. Choosing the procurement systems is risk decision. The main risks obtained at the time of project to clients, contractors, sub-contractors, design team and suppliers are in completion deadlines, construction cost, design adequacy, liability or defects, safety, quality, workmanship etc.,. Source: Turner (1997) Building Procurement (2nd Ed) Source: Smith (1999) Managing Risk in Construction The contractors or consultants are selected by some competition or negotiation with a single organisation. In short listing tenders the points to consider were, Financial standing and records Experience in similar contracts in recent periods. Capable management. Capacity. Time, Cost and Quality of construction are the different options used to address the clients objectives. There are many different procurement methods available. Some have a long life which was continued till now. Some are disappeared. It depends on the results of the past projects. Some systems are in extensive use. Some will suite for the contractor. Some will be suitable for the clients. Procurement types: Lump sum or traditional procurement Design and build Management contracting Framework agreement Public private partnerships Construction management 1. Traditional procurement: This is most common method of procurement. It is suitable to all clients, including in experienced clients and it is time predictable and cost certainty. It is suitable for fast track projects. In this method client appoints a team of consultants to prepare drawings and also tender documents. The client appoints building contractor as well, to build the structure as per design with completion date as per approved rates. Most work will be distributed to the sub-contractors and the contractor remains responsible. Client appointed consultants administrates the project and advise the aspects associated with progress, design and payments. This is low risk option for the clients to minimise the delays, design failures etc. But some times the risk will increase, when the design phase is rushed and also when tender documents are not fully completed. The two stage tendering is referred as the accelerated traditional method. By this design and construction process will at the same time for a w hile. 2. Design and Build: In design and build procurement system a single contractor or single consultant will be appointed for both design and build or management of construction operations. Subcontractor will be appointed by the main contractor or consultant. The main characteristics of this procurement method are: Single organisation will be appointed for both build and construction of project. It may be contractor or consultant. The construction works will be carried out by subcontractors when handled by the contractor when the project is given to contractor. Client will manage subcontractor when the project is given to the consultants. The design and build procurement system is defined as: Design and built organisation behaves as consultant with direct contact with client for design and building of project. All packaging works are between designs and build organisation. Diagram : Flow chat of Design and Build procurement method Using this contract design and build system, clients obtain single or two competitive bids. The suitable contractor who contains the clients requirements and design will be issued the contract. Tender requires stating lump sum management fee and also offers a guaranteed maximum price in the bids. The contract awarded is mainly based on financial level. The GMP approach will also sometimes considered by the client at the time of management contracting. Management procurement systems are undetermined by instance of GMP involvement with agreement between contractor and employer. This is not demanded in design and builds type of procurement system. The design of project will be carried out by in-house designers, external consultants or by both of the in-house designers and external consultants. Whatever is the source of the design, the total responsibility is on the design and build contractor. There is a close contact with clients, designers and subcontractors. This will make the project quite easier. Whatever the problem occurs i.e. in design, packaging works and price issue, he can approach everything and everyone directly in this design and build method of procurement. Construction work is carried out by means of trade. Work packages and it enable to overlap the design and construction. This conditions made the design and build contractor to provide site establishment works. The best example of using the design and build procurement method is construction of  £25 million Nissan car plant complex at Washington in 1984 to 1985. This approach highlights the difficulties that can cause by all of the management oriented methods to cope the client decision till last moment. Apart from difficulties this method provides accurate final cost of the project. Any late changes are likely to be a current or complete work may delay the entire process of the project. Late changes are agreed by such alteration, if something necessary can be allowed. In most projects the client will appoint the financial consultants, usually quantity surveyor to give advice on financial and contractual aspects of the project. Once the design and build contractor appointed, the formulation of work packages, financial monitoring and control of project is subject of joint management and lies between two parties. Design and build usually compensate sum of: Management fee Design fee Net cost of site establishment Final accounts of all the subcontractors to the GMP. When GMP is in corporate in contract it is accordance with the tender documentation. If the contractor made savings against GMP will be penalises when sum exceeds as a result of mismanagement. Payments will be made on net cost of work contractors. Open book method accounting will be done in designing and build method to make the financial records available for the clients or financial advisor, to verify the actual cost of the project with records. The quality control will be problem with the duty for functions allowed to the design and build contractor. But developing quality control was done by form of inspectors, which were appointed by the client. The contract is an initiative to the contractor to minimise the costs and also need him act as an independent consultant. In this circumstances the quality may drop down, unless additional care was taken is supervision of specification of materials and equipment. Employing and managing the supervisory staffs are must undermine the relationship between design build contractor and the client who indented to form fundamental basis for the success of project where design and build type of procurement method is used. When consultant led design and built is a practical and commercial approach to implement the project. The system creators belief that the most construction projects suffer as a result of poor communication and unwanted large and complex management hierarchy, over planning and lack of commitment to the clients cause by most participants in the project. The principles for management of project were: Drawing and documentation is not a product by means o communicating the clients requirements to the construction manager. Communication between the employees is as direct as possible. As we expecting changes in construction field, full preplanning is not the best control and more flexibility and less detailed short term planning should be adopted. The interest of client is best served to participant to the project objectives not individual aspirations. 3. Management contracting: Management contracting is one of the most common methods of procurement. In this client appoints consultants to prepare drawings and project details. The management contract was selected by tendering, paid bases, prime costs and management fee. The main role of management contract is to manage the execution of work. The main contractor does not involve in any kind of construction work directly. It will be done by packages which were undertaken by sub-contractors, which were appointed by management contractors. In some cases the management contractors also agree design liabilities. In this the works contracted were directly and contractually responsible to the management contractor. The management contractors obligation is to accept responsibility for design and construction means. It referred as Design, Manage, Construct it is called as featured as contractor-led procurement. In this the led designed responsible for overall design and manager was responsible for coordination of work. It is suitable for fast track projects, complex buildings and developing brief. It is not suitable for inexperienced clients. Cost certainty, and not possible to transfer the total risk to contractor. This approach will overlap design and construction progress. The payment is made on the basis of cost of work with agreed fee by the managing contractor. Success of project is mainly depends on the contractors team. Price certainty is less because the construction starts before completion of all design works. This means many of packaging works to be tendered later in the construction stage. Means the design and work packages are adjusted properly to keep the project within the budget. Design and construction tends to be less than design and build methods. 4. Framework agreement: Framework agreement is established with limited number of suppliers or single suppliers. It will allow suppliers bring together with relevant experience which will save both the parties when more projects involved. This method of procurement includes all forms of procurement methods. Like traditional, design and build etc. the developing framework agreements for consultancy service will be done by LSC (Learning and skill council). Reduced transaction costs Continuous improvement within long-term relationships Frame work agreement with number of suppliers or single supplier can result in significance savings to both parties. No need for constant re-tendering at call of stages. When the contract conditions are unchanged for all projects, there will be substantial gains from continuous improvement. When the term changed, small competitions with in frame work will takes place. Client may have more framework suppliers for different requirements. The resource implications for client should be decided whether they need one frame work supplier under one frame work agreement are not. Frame work agreement may be used for design and build and primary contracting procurement methods. Frame work agreements also suitable for maintenance requirements. Client with small and rare project will consider collaborating with similar type to share frame work agreement. Every frame work agreement completed and advertised with procurement rules. There must not be any commitment to the frame work agreement contractor for any other kind of business until the first contract completes. The savings in cost and time will come from the following: Not necessary to rebid for every individual project. Continues development will earn by transferring from one project to another. Working relationships will be improved. Continues work flow. Speed of procurement. Public private partnership: Public private partnership is a partnership between public and private sector means the government and private parties carried out the project together on the agreed division of tasks and risks. Each party keeps its own identity and responsibilities. The public private partnership is growing due to demand in infrastructure. The limited fund in the public sector leads to join with private sector, in this provision of infrastructure. The principle believes PPPs is that the public sector is responsible for the proper delivery of service and it is not responsible for actual providing service. Major public sector projects have always undertaken by private sector contract. The major difference between all the procurement methods and this method was, private sector regarded as a fully fledged performer. The essential characteristics were: Responsibility and risk is transferred from public sector to private sector. The contractual agreements were made to perform based outcomes. Long term contractual agreements. Identification Option analysis Planning and approval Implementation Post-transaction Political risk Construction management: In construction management procurement the total services were been between the package contractors and clients. This will show the difference between management contracting. In this approach the client will contact directly with sub-contractors. Here the construction manager acts as an employee agent. When dealing with sub-contractors. The main points in this system are: Construction manager was appointed as consultant at initial stages and have equal status as design team members. Payments are made by lump sum or percentage fee to construction manager. The main works in the projects are carried out by sub-contractors. The role of construction manager is to supervise, co-ordinate and administrate. The role construction manager is defined as consultant role and responsible to the client. The construction manager work for a safety and all works are carried out by sub-contractor, between client and sub-contractor. This type of procurement method was first started in US during 1960s. They usually called this method as construction project management. This procurement method was started to use in UK in 1970s. This was needed to control the risk, cost and time in large projects. After the uncertainty in the worlds economy takes place the higher interest rates made commercial builders to large financial risks. From that stage this method was used in major projects. There are variations in construction management procedures. The construction manager has the equal level as designers. The both designer and construction manager have a direct contact with clients. In construction management method the involvement of client is more than the other methods. Thus this method will be taken by the entrepreneurial clients, who have ability and resources, unless they must be ready to appoint construction manager to protect their interest. Tough process will takes place to appoint a construction manger. The main roles of construction manager: Planning and management Inception and completion Design to ensure built ability. Value for money and economy. Advising the client of their time and cost. Safety policy for the site. Division of work to appropriate sub-contractors. Interim payments and final accounts with work contractors (sub-contractors) and advising client with proper documentation. Before starting of the project construction manager also involves in preparation of project cost budget. Also involves in preparation of tender documents and solution of potential subcontractor and managing tender documents, evaluation and recommendations in acceptance of tenders were also done by the construction manager. Construction manager will not do any construction work by his own. Construction manager was responsible for control and co-ordination of subcontracts. Programme control and time management. Applications for the payment to the subcontractors were examined by construction manager. The manager will submit the applications to the client with appropriate member of design team. Advantages and disadvantages: Traditional method: Advantages: Design was fully developed and cost is detailed before the building contractor being signed. This method will give clients very customised building. The design and construction was split into separate sections will give clear responsibilities. Disadvantages: Its difficult to fine the responsibility for errors and omissions. Different parties involved in the contract can create climate antagonistic. Unexpected circumstances will change the final cost of the project than original tendered amount. But proper planning keeps this under control. Design and Build method: Advantages: Single point of Responsibility: the manager is responsible for design and construction. The client should have single point of responsibility. This method is more advantageous than other, where the client employee separate designers and construction agreements. If the claim is done, the contractors, designers and architects blame each other of their responsibility. Price certainty: Design and build gets more price certainty than other forms of procurement methods. Many of design and build contractors include guaranteed maximum price (GMP). Design and build contractor cant claim for loss and expenses for late instructions from architects. This kind of claims can be done under traditional form of procurement method. The fee paid for the professionals is also less and depends on the roles of the professionals. Speed: It can be easily achieved from design and build method, by starting the work at site earlier than the traditional forms of contract. The contractor is not relaying on design and supply information, this is called single point of contract. This type of method will allow budget and programmes level of control to the contractor. So the construction process is likely to be quicker. Buildability: The contractor is responsible for design and construction, so the project is more likely to be buildable than other procurement methods. Claims: Its not easy to claim because its a single point of responsibility. Disadvantages: Design quality: Design and build method is not an exact procurement method where high priority of design quality is not given because of certainty among the architects. Additional design fee: If the client likes to take independent advice on design matters where the building contractor involved, then this will cost the client to pay additional fee to the design team of the contractor. Inflexibility: Once the contract proposal is agreed, the scope for client to make changes in his requirement is less otherwise the cost consequences will be prohibitive. Management contracts: Advantages: This system enables client to obtain Guaranteed Maximum Price (GMP) for the construction element of project from the management contractor. It is used to accelerate the project process. The risk of delay will be overcomes by timely targets. Disadvantages: Project cost incurred in this system is higher, when compared with design and build system. When guaranteed maximum price (GMP) achieves, the management contractor position with clients as consultants will be at risk. Framework agreement: Advantages: Single tendering for the life of the framework agreement. Reduction of cost and administrative efforts. Initial tendering allows contractors to know competitive supply and should offer competitive prices for expected value of business. The range of supplies will be provided is short time by contracting authority, it reduces the stock holding for goods and also reduces time and equipment maintenance and repairs. Long term working relationship can be established with the supplier. Disadvantages: This is a closed system, once the framework agreement is established then new suppliers cannot be admitted. Competitive reopen can be considered onerous, if its structure is not planned properly in framework agreement. Public private partnerships: Advantages: Value for money Risk transfer Long term nature of contract Performance measurement of contracts. Private sector management skills Cost efficiency Time to delivery saving Reduction on the public treasury Board support Improved cost calculations Disadvantages: Insecurity Higher transaction cost Higher capital cost Inefficiencies Culture gap Short term rigidities Construction management: Advantages: Positive attitude and more constructive being exhibited at all levels. i.e. management, supervising and operative level. The proper using of value engineer by construction manager. Clients involvement is a bit higher when compared when compared with remaining procurement methods. It will promote better working relationship with project team. In this method the clients will direct contact with subcontractors, which will improve subcontractors cash flow. Means direct payments from the clients. Disadvantages: Client must involve deeply into all course of works. He must also able to manage construction manager and design consultants. The fee to the construction manager will vary from project to project; it will depend on the size of the project and roles of the construction manager. Procurement strategy: The customized nature of construction project increases inborn risks. These risks include the work which was not exactly required in the project completion. This includes late delivery or costs more than the client pay. These kinds of risks will impact clients core business. The procurement strategy should balance these situations at early stages. The main points which are co-dependent and frequently in tension are: Time: Speed and certainty of completion as per deadline. Cost: Level of price and certainty in cost. Quality: As per performance and functionality. Procurement strategies will accomplish, Cost and time certainty for the design is developed by an architect. This consequently slow process. Also know as traditional procurement process or design-bid-build process. In cost certainty and relative speed, the design is responsibility of a contractor. Gradually client will lose the control over the design process in design and build procurement. Virtual speed for the design developed by an architect and cost is uncertain till completion called as management contracting or construction management. After careful analysis of the project brief it is clear that the main factors essential for the project are time, cost, quality and reputation of the organization. In time, cost and quality the top priority goes to time and then followed by cost and quality. So the procurement method which is going to be selected should be very efficient and fulfil all requirements and objectives of the project. The selection of procurement system depends upon the nature and objectives of the project. After careful considerations of all the above factors and objectives of the clients organization the design and built contracting procurement method is suggested as it is best suitable for the client

The Production Of Ammonium Nitrate

The Production Of Ammonium Nitrate Moreover, the emission of SO2, NH3 and NO in the atmosphere and particular matter of the secondary compound can form also ammonium nitrate. At room temperature and standard pressure, the ammonium nitrate looks like white crystalline solid. The three figures below show the structure formula, and ball-stick model of the crystal structure of ammonium nitrate. Ammonium-nitrate-xtal-3D-balls-A.png Marketing the ammonium nitrate as fertilizer became famous worldwide since 1920s. Than the market started to become low in 2001 and 2002 due to the security concern that followed in September 2001 attacks on the World Trade Center which made it very difficult to produce, transport and handle ammonium nitrate. After that, because of the changes that accrued in agricultural subsidy policies, urea has become the most important compound. This is because urea has miner safety issues, higher nitrogen fertilizer content, and it is less expensive to manufacture. In 2004, the consumption of ammonium nitrate started to improve. The ammonium nitrate is concentrated so the amount of ammonium nitrate present is more than in a given quantity of solvent such as water, NH3 and HNO3. This process is done in an evaporator. The feed enter the evaporator tank which is supported with the re-boiler heat exchanger. The heat exchanger re-boiled the ammonium nitrate solution until the solvents such as H2O, NH3 and HNO3 evaporated leaving a more concentrated solution called melt ammonium nitrate. Usually the amount of melt ammonium nitrate melt resulting from the evaporator is 95% to 99.8%. In addition, the evaporated solvent will be recycled back to the CSTR. Additives such as magnesium oxide or magnesium nitrate which they are not widely used are sometimes added to the melt ammonium nitrate for many reasons. One of the reasons is to increase the crystalline transition temperature of the final ammonium nitrate solid product. Moreover, they are used to reduce the caking by removing the water or any other liquids, and to reduce the freezing point of molten ammonium nitrate to allow solidification to happen at a low temperature. The additive and the molten ammonium nitrate are mixed in a static mixer. The most common process to produce solid ammonium nitrate with the spherical shape is prilling process. A prill tower is used to produce the prills of solid ammonium nitrate. On the top of the prill tower, the concentrated melt of ammonium nitrate melt is sprayed, and on the bottom of the prill tower, an air is rising by a blower. The falling droplets of ammonium nitrate is cooled and solidified into a spherical prills when they are encounter to a rising air. Sometime the end products have low density prills due to the concentration of the molten ammonium nitrate. The low density prills have more porous than high density prills. Therefore, the prills will absorb moisture content more easily, and may cause lamps and product deterioration. Drying process by vaporization is required to remove water or any other liquid from the solid ammonium nitrate prills. In a static bed tower, the solid prills are placed there and from the bottom of the tower, a hot air is passed through the solid prills. The desired end product is spherical ammonium nitrate solid. However, the solid product may produce in variety of sizes. A screen process is needed to check consistently the sizes of the solid product to have only the required size. The off size prills are recycled back to the evaporation process. The right size prills send to a cooling process, where it cools down the end product for further operations. Coating process is needed to protect the product from agglomeration during storage and shipment. However, sometimes it is not needed. This is because the additives that were added before was melted before solidification. Therefore, there is no need to coat the products with clays or diatomaceous earth for product protection. Finally, the end products of ammonium nitrate solid prills are manufactured. Therefore, there are ready for storage or shipment by bulk or bags. 2. Production of granulated solid ammonium nitrate Processing granules solid ammonium nitrate is the same as the first production of prills of solid ammonium nitrate. However, this time instead of using prill tower, it uses rotary drum. This occurred by spraying concentrated ammonium nitrate in a rotating cylindrical drum onto small and fine particles of ammonium nitrate. As particular rotate in the rotary drum, layers of NH4NO3 are added to particles which form granules. The NH4NO3 solid will than goes to the scanner. The ammonium nitrate granules are cooled down to avoid lamps. The under-size granules are crushed and recycled back to the rotary drum as particles. On the other hand, the oversize granules are dissolved and recycled back to the solution process. 3. Ammonium nitrate solution process: Ammonia gas NH3 and nitric acid solution HNO3 is added to a neutralization reactor. This process is an exothermic neutralization reaction which produced ammonium nitrate solution with steam. Therefore, the reactor that used is jacket continues stirred tank reactor the resulting steam which is vapor water, ammonia, and nitric acid is send to the ammonium nitrate scrubber to remove it from the neutralization reactor. The steam can be purified or can be condensed than purified. In addition, the steam can be used in the evaporator to concentrate ammonium nitrate solution or a pre heater. . The resulting solution is send to random tank after the solution is cooled. Finally the product is shipped to other plants for further processing. The picture below shows the production of ammonium nitrate solution. Process selection: The most significant aim in producing ammonium nitrate is to enhance the properties of agriculture around the world as a fertilizer. It improves the growth of the plants, gives nutrition, and makes it healthy and free from diseases. It is cheap and available in agriculture stores. It can also be used in explosive, but it is very dangerous and risky. It affects the public safety in the country. Therefore, production of spherical solid ammonium nitrate process is the best selection than the others for many factors. Around 60% in the US and in other European countries companies produced solid ammonium nitrate NH4NO3 as a fertilizer. Moreover, granulation technique is old technique and it requires more complicated plants and a variety of equipments such as rotating drums, fluidized beds and more. Currently, there are no plants in Europe using this technique any more. Nowadays, most fertilizers companies use prill technique for the production of solid ammonium nitrate. Conclusion In brief, the production of ammonium nitrate was done by adding ammonia gas and nitric acid solution. The production of ammonium nitrate passed through three main unit operations, which they are neutralization, evaporation and solidification. The choice of the final product was influenced by the commercial matter. Chemical and physical properties ammonium nitrate shows how it can be used in industrial market. It can be used mostly in agriculture and as explosive agent. The aim of the process was to produce a spherical solid ammonium nitrate as a fertilizer to help improve the agriculture market. The prill tower was used instead of rotary drum to get the required end product. Some diagrams such as block flow diagram, process flow diagram and Aspen Hysys diagram was drown to shows the flow of the ammonium nitrate production.

The Hole In The Net :: essays research papers

Our social safety net has a hole in it. The fibers of the net are decaying; the hole is getting bigger. More people are falling through, and the people with the least strength are holding the most of the weight. Three to four million Americans are homeless according to the U.S. Department of Housing and Urban Development, 5.5% cannot find jobs according to the Bureau of Labor and Statistics, and the figure is over twice that in the 20-24 year old age group, according to the Department of Education. A very slim minority of these people are sucking off the system, but the vast majority just had a bad break. Such is the story of Peter and Megan, as told by author Jonathan Kozol in his Robert F. Kennedy Memorial Book Award winner Rachel and Her Children: Homeless Families in America. Peter was a carpenter and she was a homemaker who raised their five children. They lived in a neat, working class apartment building in New York City. Peter did construction for public housing projects, and had a vast array of technical skills and tools: â€Å"I did carpentry. I painted. I could do wallpapering. I earned a living. We spent Sundays walking with our children on the beach.† It may sound like this was a happy family, living the American Dream. Perhaps they were -- they were self sufficient for all of the 12 years that they had been married, they had a steady income, a close and loving family, a home, and a chance for their children to do even better than they had done. Then the fire struck. They came racing home after hearing the news, only to find that everything had been destroyed. The children lost their pet dog and cat, Megan lost her grandmother’s china, but Peter perhaps lost the most: his tools. Since the fire, he has not had a job, because a carpenter without tools might as well not have eyes. He explained that for every job he had, he would add a new tool to his collection. But they all went up in the blaze. When Kozol first met them, they were living in a welfare hotel in New York, where they had been living for two years. They can’t get out because federal assistance programs (better known as welfare) tell them that their family limit for an apartment is $366 a month -- this with seven family members living in New York City. (In comparison, that’s about the rock bottom price for a week in a New York City one room motel.) In their two room â€Å"apartment†, the entire place is falling

Muckrakers :: essays research papers

Muckrakers were early twentieth-century reformers whose 1 mission was to look for and uncover political and business corruption. The term muckraker, which referred to the "man with a muckrake" in John Bunyan's Pilgrim's Progress, was first used in a pejorative sense by Theodore Roosevelt, whose opinion of the muckrakers was that they were biased and overreacting. The movement began about 1902 and died down by 1917. Despite its brief duration, however, it had a significant impact on the political, commercial, and even literary climate of the period. 2 Many popular magazines featured articles whose purpose was 3 to expose corruption. Some of these muckraking periodicals included The Arena, Everybody's, The Independent, and McClure's. Lincoln Steffens, managing editor of McClure's (and later associate editor of American Magazine and Everybody's), was an important leader of the muckraking movement. Some of his exposà ©s were collected in his 1904 book The Shame of the Cities and in two other volumes, and his 1931 autobiography also discusses the corruption he uncovered and the development of the muckraking movement. Ida Tarbell, another noted muckraker, wrote a number of articles for McClure's, some of which were gathered in her 1904 book The History of the Standard Oil Company. Muckraking appeared in fiction as well. David Graham Phillips, 4 who began his career as a newspaperman, went on to write muckraking magazine articles and eventually novels about contemporary economic, political, and social problems such as insurance scandals, state and municipal corruption, shady Wall Street dealings, slum life, and women's emancipation. Perhaps the best-known muckraking novel was Upton Sinclair's 5 The Jungle, the 1906 exposà © of the Chicago meatpacking industry. The novel focuses on an immigrant family and sympathetically and realistically describes their struggles with loan sharks and others who take advantage of their innocence. More importantly, Sinclair graphically describes the brutal working conditions of those who find work in the stockyards. Sinclair's description of the main character's

The Natural Force Of Tides Environmental Sciences Essay

The term Tide is defined as the rise and autumn of H2O degree in oceans and seas as a consequence of the natural force of gravity between the Earth, Sun, and Moon, in add-on to the rotary motion of Earth on itself. Tides have been known to ancients a long clip ago, nevertheless the scientific apprehension of this capable affair was non until three centuries ago, when Newton presented his book â€Å" Mathematical Principles of Natural Philosophy † or as frequently named, the Principia. In this book, Newton described the Universal gravity, which shaped the scientific position and account for the natural admiration of Tides.ImportanceLearning about the natural force of tides and tide anticipations is a necessity for any seaman. Tides can be either utile or insidious, all depending on how the seaman trades with it. A high tide, for illustration, can be utile because it raises the ship a little more above H2O giving the ship a better clearance distance between the bottom surface of the ship and the sea land. In contrast, a high tide can be unsafe on ships, because it can force ships to the shores instantly if non moored in a clear infinite. Similarly, a low tide may be unsafe, because it pulls the H2O off from the shore doing the ship to hit the land doing amendss to the ship. The rise and autumn of H2O degree, and currents caused by tides may either assist the ships motion and patterned advance or detain it, may take ships into dangers and hazards or off from them. In order to hold a safe and a successful journey, the sailing master in any sailing ship must hold a clear apprehension of tides, in add-on to doing usage of tide anticipations available in published tide informations tabular arraies from all ports around the universe.Earth, Moon, and Sun SystemAs mentioned antecedently, tides are the consequence of two factors, the gravitative force of the Sun and Moon towards Earth, in add-on to the Earth`s rotary motion around its axis. Obviously, all planets, including Earth, in our solar system depend on the gravitative force and rotary motion around the Sun to be balanced and organize a common system of several planets. The gravitative force of the Moon and the Sun plays a bigger function in the creative activity of tides on Earth. As the Moon rotates aro und the Earth, it exerts a pull force towards the earth`s surface. The Sun on the other side exerts another pull force on Earth to the Sun, see figure 1. The Moon, nevertheless, have the bigger influence than the Sun because of the shorter distance it has to earth, even though the sun`s gravitation towards Earth is 179 times stronger than the Moon. The short distance between the Moon and Earth makes it responsible for 56 % of the force impact on Earth and 44 % will be from the Sun, and this explains why the tides are specifically linked to the Moon behaviour. tide-tables-a-2.jpg Figure 1: The Moon and the Sun exerts gravitative Pull forces towards the Earth, doing the creative activity of tides. ( Beginning: hypertext transfer protocol: //science.howstuffworks.com/environmental/earth/oceanography/tide-table1.htm ) As the Moon rotates around the Earth it creates a bump of H2O on the earth`s surface traveling parallel to the Moon, ensuing in the formation of tides. An tantamount bump is besides formed on the other side of the planet antonym to the Moon. The tantamount bump on the opposite side of the planet is caused by Earth being pulled off from its H2O, in the opposite side, traveling towards the Moon. Another name for the cause of the opposite bump is the centrifugal force of the Earth ‘s rotary motion. By and large talking, the pull force of the Moon and the Sun influences the whole planet Earth including the land country and H2O country. The big volume of H2O on Earth ( 71 % ) moving compressible as a fluid, nevertheless, makes it more noticeable and extraordinary. The day-to-day rotary motion of the Earth around itself and the Moon go arounding around the Earth, all reflects the tidal rhythm. The Moon revolves around the Earth one time in what is called a lunar month. The lunar month represents the clip between the happening of a new Moon and the consecutive 1. The continuance of the lunar month is calculated about to be 29days 12hours and 44minutes. Having the Moon go arounding around the Earth one time every lunar month and the Earth revolving in the same way daily on its axis, the whole planet will necessitate more than 24 hours to catch up with the proceeding Moon. Earth needs 24 hours plus about 52 proceedingss to finish a tidal rhythm. This Moon based twenty-four hours is called the tidal twenty-four hours and it consequences in the changing of the tides` timing of each twenty-four hours by adding about 52 proceedingss. In theory, this tidal rhythm consequences in two high tides and two low tides in all of the Earth. The two opposite bumps of H2O on Earth, explained before, represent the high tide which follows the motion of the Moon straight. The other two parts of Earth, between the two bumps, represent the low tide. Tides are classified into diurnal, semi-diurnal, and assorted tides in conformity to the highs and figure of high and low tides each tidal twenty-four hours. A Diurnal tide is when a certain location on Earth experiences one high tide and one low surge a twenty-four hours. Diurnal tide happens in locations of high latitudes when the H2O bumps formed by the Moon drawing are north or South of the equator, see figure 2. A Semi-diurnal tide is the most common in the bulk of topographic points on Earth, and it is when a certain location on earth experience two high tides and two low tides a twenty-four hours. Semi-diurnal tide happens when the Moon is straight above the equator. While the semidiurnal tides assures two equal high tides and two equal low tides for locations near the equat or, locations north and South of the equator experience two but unequal high tides and two unequal low tides called a Mixed tide. diurnal. ( 1 ) .gif Figure 2: Diurnal tides take a period of 24 hours and 50 proceedingss. Semidiurnal Tides period is 12 hours and 25 proceedingss. The country in between experience Mixed tides, where two but unequal high and low tides takes topographic point. ( Beginning: hypertext transfer protocol: //oceanlink.island.net/oinfo/tides/tides.html )Annual Tidal BehaviorThe Moon revolves around the Earth in an elliptic way, which makes it closer to earth at times and farther off at other times. The clip in which the Moon is at its nearest distance with Earth is called Lunar Perigee. The closest distance the Moon can come to with regard to Earth is 356,400 kilometers, which is less than the average distance between the Earth and the Moon by 8 per centum. As mentioned before, Newton in his book â€Å" Principia † described his theory of the gravitative existence, where he besides developed a expression to cipher the gravitative force between two organic structures. The Newton jurisprudence of gravitation proves that gravitative forces between different organic structures addition as the distance between the two organic structures lessening. As a consequence, the 8 per centum lessening in the distance between the Moon and the Earth increases the gravitative force of the Moon by 25 per centum, impacting the Earth and increasing the ability of the Moon to bring forth tides. Actually, when the Moon is at its nearest distance with Earth and standing in a line between the Earth and the Sun, unusual increased high spring high tides are produced. Besides named Proxigean Spring Tide, the high spring high tides occur non more than one time every one and a half twelvemonth. In add-on, if the lunar perigee occurs at full Moon ( Earth between Sun and Moon ) , unusual low Neap tides besides takes topographic point. The gravitative force developed because of the Earth and Moon interaction, and its impact on the big organic structures of H2O in Earth develops an hyperbole event called â€Å" evection † . This event takes topographic point when the Moon is at its nearest distance with Earth and stands between the Sun and the Earth in a consecutive line ; Proxigean Spring Tide. When other factors of high storm, or complex natural occasions takes topographic point at times of proxigee, Deluging with large amendss and extraordinary tides hit certain seashores. The last Extreme proxigean spring tide taking topographic point was in March 7, 1995. Extreme proxigean Spring Tides have been recorded for the past 400, and is said to happen one time every 31 old ages.Tidal RangeThe difference between the high tide and the subsequent low tide, vertically, is called the tidal scope. The tidal scope calculates the difference in the H2O degree or highs between the high tide and low tide. As have been ment ioned before, the gravitative force of the Moon and the Sun on Earth is the major cause of tides. It is besides discovered that the altering stages of the Moon has a major impact on the highs ‘ alteration in Tides in different seashores and locations around the universe. Around the clip of the new Moon or full Moon, the maximal tidal scope takes topographic point ; tides are highly high or really low. This happens because the gravitative force of both the Moon and the Sun is aligned in the same way toward the Earth ( new Moon ) , or aligned in opposite waies, holding the Earth precisely between the two forces ( full Moon ) . During these two stages of the Moon, tides are called Spring tides, see figure 3 ( a ) . On the other manus, During the first and last quarters of the moon`s stages, tidal scope tends to be smaller. This happens because the place of the Sun and the Moon is at a right angle to the Earth. The gravitative force of the Sun and the Moon acts weaker to the earth `s H2O because it comes from two different waies. During these two stages of the Moon, tides are called Neap tides, see figure 3 ( B ) . In each twelvemonth there are two yearss when the length of the twenty-four hours and dark are equal, called Equinox. The maximal tidal scope to expect yearly is said to be during the clip of equinox when combined together with a clip of spring tide. tidal_cycle.jpg Figure 3: ( a ) Spring tides occur in new Moons and full Moon. ( B ) Neap tides occur between new Moons and full Moon. ( Beginning: hypertext transfer protocol: //www.icit.hw.ac.uk/student_project/sweyn3.htm ) It is partly true that the tidal scope additions as farther the location is from the equator. However it is non the lone factor of increasing tidal scope. Hundreds of seashores in the farthest North or South of the equator tend to hold smaller tidal ranges than 1s near the equator. Several Stationss on the Korean seashore, for illustration, have a tidal scope above 20 pess. On the other manus, some Stationss on the Bering Sea near Alaska have the tidal scope of 5 to 7 pess. The addition or lessening in tidal scope in any seashore depends on many physical factors of the location itself. The characteristic of the land where the seashore is located is an of import factor impacting the tidal scope, in add-on to the form of the shore. Another factor playing an of import function on the addition or lessening of the tidal scope is the deepness of H2O in the location. Likewise, the size of the ocean basin where the tide happens is a major factor for the alteration in tidal scope between diff erent locations. Large countries of H2O, like oceans, are capable to a more country of influence by the Moon gravitation than smaller countries like seas, bays, or gulfs. Tidal Range is classified into three sorts based on the measuring of highs. First, Macromareal, named for tidal scope higher than 4 meters. Second, Mesomareal, named for tidal scope between 2 to 4 meters. Third, Micromareal, named for tidal scope less than 2 meters. Extreme conditions conditions of strong air currents in a steady way with a long clip continuity, combined with low force per unit area can act upon the tidal scope progressively, particularly in narrow bays, and gives false measurings. Tsunamis and deluging comes from the oceans and sea, nevertheless, are particular instances of risky conditions that is non included in the measurings of tidal scope. Tide informations of different Stationss in states with H2O seashores normally contain tabular arraies of day-to-day measurings recorded or even day-to-day and one-year anticipations of Stationss in this state. The National Hydrographic service of the state publishes these informations tabular arraies and is available to order if needed.Highest tidal scopeIn the east seashore of North America, specifically, Nova Scotia in Canada one of the world`s greatest admirations takes topographic point. The Bay of Fundy in Canada has the world`s highest tidal scope. An sum of 100 billion tones of H2O is filled and emptied from this bay twice every twenty-four hours. Towards the caput of the bay, in the Minas Basin, tidal scope reaches more than 16 meters. The highest tidal scope recorded in this bay was at Burntcoat Head. The highest tidal scope at Burntcoat Head was measured at 16.65 meters. This information measuring is of import for the design of the tidal trial armored combat vehicle. Suppl ying the design of the tide trial armored combat vehicle with the maximal tidal scope informations recorded on Earth and the application of these measurings on the ship theoretical accounts give the companies a opportunity to develop their ships in order to be successfully used anyplace in the universe without worrying about tides and H2O degrees.Tidal currentsTidal current is another term related to tides and has a great importance in ship seafaring and marine pilotage. If tides are the perpendicular rise and autumn of H2O degree, so a simple definition for the tidal current will be, the horizontal flow of H2O attach toing a normal tide on coastal countries. Tidal currents can be found in any H2O organic structure, including oceans, seas, gulfs, bays, and rivers. Tidal currents have been recorded at upper limit degrees in locations along seashores of ocean basins. Tidal currents move more straight towards and exterior closed countries like estuaries, seaports, or rivers. Together with tides, tidal currents move in a certain way with the high tide and in the opposite way with the low tide. When a tide takes topographic point on a certain location, the H2O degree rises over clip covering the bay doing what is called Flood tide. Consequently, the H2O rises until it reaches its highest degree ; high tide. Directly after the H2O reaches its highest degree, it stops, at the seashore in what is called loose H2O. Afterward, the H2O degree starts to fall over clip, doing what is called ebb tide. Consequently, the H2O degree falls until it reaches its lowest degree ; low tide. The low tide stays for a period of clip in once more what is called loose H2O. This sequence is somewhat different when speaking about rivers. Rivers H2O flow from the river to the sea, which evidently lowers the power of the inundation tide. However, during the ebb tide, H2O flux ing from the river to the sea is strongly supported by the wane flow doing more powerful tidal currents. Ebb flow largely prevents smaller boats from making the seashore, See figure 4. tidal current.png Figure 4: Tidal Currents develop ebb tides and inundation tides in closed H2O countries. ( Beginning: hypertext transfer protocol: //oceanmotion.org/html/background/tides-currents.htm ) Sailors and Mariness typically take attending for the measure and clip of the tide. Tides, particularly low, prevent entry to seashores of shallow H2O. Another concern for crewmans and Mariness, sing tidal currents, are the velocity, clip, and way of the tidal current. As a consequence, crewmans need elaborate information of tides and tidal currents behaviour in order to be after the ship ‘s place, velocity, and sailing itinerary.River MedwayThe river Medway is located in southeasterly England, most of it is in the county of Kent, see figure 5. The river flows precisely from Turners Hill in west Sussex, traveling through Tonbridge to Maidstone and the coastal towns of Medway into the river Thames at Sheerness before stoping at the Thames estuary. The River Medway flux a distance of 70 stat mis through the Land country until it ends at the eastern sea seashore of Kent. In the late sixteenth century, the river became a Ship Defense centre for the Royal Navy, where ships were buil t and navy arms was transferred through the river. However, river Medway has ever been a hard waterway to voyage through and bigger ships ever struggled to go through over. Ships had to restrict their seafaring above the river medway to certain tidal state of affairss, doing usage of high tides and taking cautiousnesss from low tides, hence sailing between half inundation and half ebb tides. The Chatham Dockyard, standing further up the river, near the centre of the town, was found in 1547 as a ship building and fix topographic point. The Chatham Dockyard played an of import function in most of the wars fought between England and other European states. Many celebrated ships and navy battlewagons were built in Chatham Dockyard, including the first Fe battlewagon in 1863. river medway.jpg Figure 5: River Medway gathers and flows at Tonbridge, Kent. River Medway ends at the eastern sea seashore of Kent. ( Beginning: hypertext transfer protocol: //www.woodlands-junior.kent.sch.uk/townhistory/ ) Before the twelvemonth 1746, ships coming from Sea could non go through the river after Maidstone, until at that twelvemonth many betterments were made to the river lease flatboats with heavy tonss traversing over the river stretch every bit far as Tonbridge. The river was farther improved by clip. Eleven Locks on the river take topographic point, assisting in the crossing of the river. Lock aid raise and take down the boats in certain countries of the river to assist in the crossing over. The locks in Allington and other topographic points along the river give ships a bill of exchange, or minimal distance between the ships` organic structure and the river floor, of 4 pess.Tidal River MedwayThe River Medway is divided into two parts, tidal and non tidal River Medway. Non tidal River medway is from the get downing point at Tonbridge and coatings at Allington. After Allington towards the medway estuary near Sheerness, the river is tidal. All the seafaring and pilotage through the river between sheerness and Allington is dependent on tides motion. At low tides the river Medway may dry out at locations near Allington lock. High tides are non a large of danger to ships in the River Medway as Low tides in certain locations are.River Medway at ChathamChatham experience semidiurnal tides or assorted tides during the twelvemonth. Meaning, Tides occur in two high tides and two low tides in chatham, but are sometimes are unequal. In a study by Drewry Shipping Consultants Limited in July 2007 prepared for the Medway Council and Marine South east, the undermentioned statement describes the different tidal scope of Medway River.
