Organic vs. Conventional Foods Essay

For years, there has been a debate on how food is grown. Should it be organic or conventionally grown? To answer this question, the difference between the two needs to be known. Organic produce is grown without chemical fertilizers and pesticides. Organic livestock is free ranged, most of the time, with no added antibiotics or growth hormones. Conventionally grown produce is usually processed after being harvested. They are also sprayed with chemical pesticides and enriched with polluting fertilizers. Research Stanford University has held over 250 investigations that compared the nutritional value of organic and traditional crops. These studies show that organic foods tend to contain slightly more phosphorous, a higher level of omega ­3 fatty acids, and a 30% lower rate of chemical residue. However, traditional chicken and pork is one ­third more likely to contain antibiotic bacteria than organic meats. Bacterias that cause food poisoning are equally present in both traditional and organic. They have little difference in nutritional value. Organic When people see â€Å"organic,† they immediately think â€Å"pesticide ­free.† Organic products can still be labeled as organic, even if they contain commercial pesticides. The U.S. Department of Agriculture stated that almost 20% of organic lettuce showed up as positive for containing a  pesticide   called spinosad. Spinosad comes from a naturally occurring bacterium in soil. Although it is considered slightly toxic to the EPA (Environmental Protection Agency), it can be used while farming and still be labeled as organic. Spinosad, under the name Entrust, is especially harmful to the nervous system of insects, and small marine life, like mollusks. Spinosad, as well as compounds made of natural elements like sulfur and copper, have made it onto a list of pesticides open for use on organic crops, which you can find on the USDA website. Organic farming became popular in the 1970s when the first pesticides and fertilizers were introduced. The effects of the chemicals they contained were soon noticed. The chemicals paralyzed the nervous system of many people. People became concerned with what they were consuming. Organic produce may have a longer storage time and lower input costs, but there is more bad that comes out of it than there is good. Organic crops have a longer growing time. Organic farming also requires more skill than needed for traditional farming and has higher risks of soil erosion. Despite the disadvantages, organic farming is more popular than ever. Organic products tend to have a more natural taste, and is believed to decrease the risk of the avian flu. Conventional Since organic farming is becoming so popular, traditional farming is beginning to be frowned upon. It is believed to be highly dangerous and an environmental risk. However, that is not the case. Conventional farmers are starting to focus on soil fertility techniques, such as crop rotation and composting. Although some farmers still use chemical based fertilizers, herbicides, and  pesticides, others have switched to fertilizers, herbicides, and   pesticides with little to no chemicals. Conventional farms can produce more crops per acre, replenish soil, decrease risk and topsoil erosion. Conventional farming is also cheaper and require less skill. The amount problems with conventional farming have risen over the years. These problems are becoming more serious. Droughts are a big problem when it comes to traditional farming. Crops rely on rainfall to live and grow properly. If a drought occurs, it is very likely for starvation in a community to happen. Also, crops must be sprayed with the right amount of pesticide or herbicide. If not given the right amount, crops, runoff, and local water sources can be contaminated. Suicide within the conventional farming community is also a very common thing. Since 2009, over 200,000 Indian farmers have committed suicide due to debts they could not pay off. The decreased sea levels and organic competition is the cause of their lowering profit. Price Differences The prices of organic products tend to be around three to four dollars more than regular produce and meat. Say you were at the grocery store. Your grocery list contained bread, a dozen eggs, and a half gallon of milk. If you were to buy these things as conventional products, it would cost around $7. However, organic versions of these products would cost about $11.50. Organic products, such as milk, eggs, or chicken, can cost up to five dollars more than conventional products. Which Should I Buy? Every year, the Environmental Working Group (EWG) releases two official lists of the crops with the most and least amounts of chemical residues. These lists are called the â€Å"Clean 15† and the â€Å"Dirty Dozen.† As of 2015, the crops that made the Clean 15

Responsible Accounting Essay

1. Identify at least two behavioral that could arise There are two potential behavior advantages if manager accepts and participate in the responsibility accounting system and participatory budgeting system. Responsibility accounting is used to measure the performance of people and department to foster goal congruence whereas, participatory budgeting system is a budgeting process under which those people impacted by a budget are actively involved in the budget creation process. When BSC’S manager is likely to accept the system and be motivated to attain the budget target, they were actively involved in setting the goals and know what is expected of them. It would be motivate them to plan ahead and promote goal congruence. Besides that, manager would be pleased to be responsible only for those items they can control because they have certain objective to be achieved. Furthermore, communication and group cohesiveness would be improved because managers would feel part of a team due to participate in both planning and implementation system that are to be adopted 2. Identify at least two potential problems that could arise Responsible Accounting System In BSC responsible accounting system, the two potential problems that might be arise if the manager did not accept the changes in the philosophy. First they will be a problem if they could not resent in being measured on an individual basis rather than the new system. They may have responsible for costs over which they have no control on it. So the manager must understand the new responsibilities in new culture of management and how they must operates and gives cooperation on it. If the manager did not accept the changes, they might face with the high focus on their own departments goal and this will contribute to the lack of communication between departments and to the company performance. Participating Budgeting System Participating budgeting system encouraged the manager to be more motivated in doing their jobs and take responsibility to achieve the organization goals. This will encourage creativity and also ideas to the organization  community to work as a team and giving cooperation to each other. However, overemphasis on department goals can hurt cross departmental employee relation due to the different motivation and also goals. 3. Discuss the likelihood that the system will contribute to the alignment of organizational and personal goals. Responsibility Accounting System. This system is used to measure the performance of people and departments to foster goal congruence. It means that the employees and organization are achieving and have same goals and objective. Therefore, if the company adopting this system it will help to ensure that the organizational and personal goals are aligned and help to achieve company’s objective. Since Commercial Maintenance, Inc. took the time to fully explain and communicate the system to BSC’s managers, by pointing out the advantages and encouraging their participation, organizational and personal goals will likely become aligned. Hence, it will increase the management performance as well as the company reputations. Participatory Budgeting System. Participatory budgeting is a process of democratic and decision making, and a type of participatory democracy, in which managers or employees decide how to allocate the organization budget. Participatory budgeting allows both organization and employees to identify, discuss and gives them the power to make real decisions about how money is spent. If the company implementing this system it will give benefit equally to the organization and employees because the managers and employees will involve in setting up the organization budget. They will know and understand more what the company wants and needs. Therefore, this system also will contribute to the alignment of organizational and personal goals and give lots of benefit to BSC.

Education to Children of Illegal Immigrants Essay

Education to Children of Illegal Immigrants - Essay Example At the height of immigration to North America, the country coined the title â€Å"land of opportunity.† Denying free education to children of illegal immigrants defies the American dream and the hopes that people had for the new country (Schrag, 2010). Free education for all was the main factor that differentiated America from other European nations. American progress and development was based on the government’s ability to create uniformity among its citizens through free education for all. The American legal system recognizes a child as a person who is below the age of 18 years. Such individuals are not entitled to voting or making major decisions concerning their life. In addition, the US is a leading nation in terms of respect for human rights. It is evident that most children are illegal immigrants out of their own choice. Most of the children were born when their parents had already immigrated to the country. Thus, these children cannot be identified as illegal im migrants since they did not make a choice to be in the country. The government should respect their rights to free education until they are old enough to make concrete decisions about their citizenship. The American government should consider the long-term impacts of denying free education to the immigrants. Obviously, most immigrants have hopes of becoming legal citizens of the United States. If the government continuously denies education to its citizens based on their migration status, the country will experience an education gap (Hing, 2004). Education is a major factor in the country’s development, and hence the country should not tolerate illiteracy. Denying education to such children will create long-term economic hardships for the country. Educating children prevents them from... The American government should consider the long-term impacts of denying free education to the immigrants. Obviously, most immigrants have hopes of becoming legal citizens of the United States. If the government continuously denies education to its citizens based on their migration status, the country will experience an education gap (Hing, 2004). Education is a major factor in the country’s development, and hence the country should not tolerate illiteracy. Denying education to such children will create long-term economic hardships for the country. Educating children prevents them from engaging in other social evils such as crime, drug abuse, and terrorism. Therefore, the government should provide free education to the children of illegal immigrants to promote their integration into the American society.America has a global obligation that goes beyond its domestic affairs. However, due to economic constraints, America often overlooks its global obligations. America’s in volvement in global politics and economics has made the country a key factor in promoting stability and development. Since the end of World War II, the United States has been involved in all conflicts around the world. Most of these conflicts create immigrants, most of whom end up in America. For instance, the Cold War forced many people from former Soviet states to immigrate to America for fear of persecution. Lack of proper immigration policies made most of the immigrants end up in America as illegal immigrants.

International Marketing Assignment Example | Topics and Well Written Essays - 500 words - 1

International Marketing - Assignment Example The success of companies in the highly competitive global market depends on the ability to connect and communicate across various markets. With this requirement, the company needs to acquire relevant linguistic skills, which will enable them to market the products in foreign markets (Hutson, Sinkovics & Berrill, 2011). In addition to the linguistic capability, the companies need to acquire skills on technological advancements that are applicable across the target foreign markets. In this way, the professionals are able to strategize on the suitable technological application that they use for presenting their ideas and products in foreign markets. Consequently, the company needs to employ factory managers with the ability to assess, understand and design processes and systems that support automated manufacturing. With this technique, a company increases the efficiency and quality of its production lines. Besides, with automated manufacturing, the company produces homogenous products that enable the equality of consumers across borders. On the other hand, entrepreneurship is a skill that each company requires to survive in the global world. This involves the skill to design newer strategies, with the ability to take opportunities that arise in the market. It also allows the business to grow extensively. Communication problems arise whenever a company diversifies its operation from the original founding location. With the expanding business world, the workforce in many companies is intellectually vast, spanning a variety of cultural backgrounds as well as wide geographical locations. This addresses the need for effective communication skills amongst the employees and employers, in order to attain the common objective of a firm (Hutson, Sinkovics & Berrill, 2011). It is important for people to learn the basic cultural diversity that hinders effective communication. This problem occurs in most companies, which do not understand the

Obesity in Kuwait Research Paper Example | Topics and Well Written Essays - 500 words

Obesity in Kuwait - Research Paper Example According to a study conducted by Zaghloul et al. energy intake among Kuwaitis is extremely more than what is actually required for a person. It was higher than the estimated energy requirements for almost half of Kuwaiti children and one-third of adults. The Estimated Average Requirement was exceeded by 78–100 % of the recommendation for protein and carbohydrates. It should be noted that majority of the energy drinks and foods contain excessive sugar and fat contents. Sugar and fat are responsible for causing obesity. These food and drink items are extremely expensive compared to normal food and drink items. Only high income people will be able to spend money for these items. In other words, high income is causing obesity among Kuwaitis. Another reason for obesity among Kuwaitis is the globalization. It should be noted that globalization has brought many life style changes in this world. Because of globalization, it is easy for fast food chains to establish food outlets anywhere in the world. Foreign direct investments are welcomed in almost all the countries because of globalization. As a result of that, global fast food companies such as KFC, McDonalds and Burger King are able to establish food outlets in any country at present. The case of Kuwait is not an exception. Because of globalization, a variety of fast food companies have already established restaurants in Kuwait. According to the arguments in the article â€Å"Is  Globalization  Making Us Fat† Social globalization, have a significant impact on obesity. A social mismatch is there among the people because of globalization. This mismatch results in differences in the energy consumption levels of the people. In other words, physical and cultural e nvironments are key elements behind obesity (Is  Globalization  Making Us Fat?). According to Kumiya et al.,(p.1027) in highland areas worldwide, socioeconomic  globalization  is progressing urbanization. This

How the Industrial Revolution, post 1865, influenced migration and Research Paper

How the Industrial Revolution, post 1865, influenced migration and expanded civilization - Research Paper Example In this second industrial revolution, discovery and invention, acting as the catalysts played a major role in industrial and economic growth of the nation. These developments coupled with the developments in transportation and communications were responsible for the formation of organized industries with the emergence of big business empires in various industrial sectors such as steel and oil. Consequently the markets grew deep and wide for catering to the needs of the suppliers and consumers. These developments resulted into migration of people from different parts of the country to the urban industrial centers and different parts of the world to the US with the urban growth taking place at a rapid pace. These migrations were responsible for the diverse cultural background in the society. Industrial development The growth of industries was very fast during this period. The consumption of steel is an indicator for industrial development. The consumption of steel in the industrial and construction sector increased during this period and fuelled the growth of steel industry. The mass production of steel through innovative methods introduced by Carnegie made it cheaper and the demand for steel increased exponentially. This has accelerated construction of railroads across the country which stimulated the growth of business and industries by rendering mobility to the goods manufactured for reaching the customers throughout the country. Similarly, the growth of oil industry has changed the way the people were living in the US as its consumption was closely linked to general industrial growth, transportation and social life. Invention of telephone and telegraph aided industrial and economic growth further. â€Å"†¦the most dramatic improvement in the speed, breadth and reliability of news cov erage came with Samuel Morse's invention of the telegraph. Newspapers became the major customers of the telegraph companies, and the cost of telegraph transmissions led to the formation of wire services like the Associated Press, which was founded as a cooperative venture by New York newspapers in 1848† (Stephens). Freedoms to press, free market economy and the capitalist system of the country encouraged entrepreneurship, and it attracted people from all over the world to the US. The opportunities available in the industrial centers for employment, profession or education caused migration of people to urban areas. The new techniques used in agriculture have increased productivity. The proportion of people employed in agriculture has come down. The agricultural laborers from rural areas migrated to cities in search of employment. Steckel states, â€Å"The importance of migration to urban growth is also indisputable. Because birth rates were low but death rates were high, migra tion fueled urban growth during the 19th century. Indeed, many cities and towns would have declined in size without an inflow of people that replaced the excess of deaths over births† (p. 1). Capital formation and emergence of corporate companies Referring to New York Stock Exchange, Teweles & Bradley says, â€Å"The vast development of the railroads was particularly important to the Exchange since those corporations were the chief issuers of securities in the trading market. About 70,000

Consider the Plan of Ayala in light of the Declaration of the Rights Essay

Consider the Plan of Ayala in light of the Declaration of the Rights of Man - Essay Example This is because â€Å"one’s right ends when another’s right begins†. Aside from that, the Declaration of the Rights of Man was perpetrated to curb the abuse of power of the legislative and executive powers of those that are in position which was one of the strongest causes of chaos and disillusionment among societies. The declaration is supposed to provide utmost transparency of the government’s responsibility to its people which indeed gave way to the close scrutiny of those in power’s action at any moment by all political institutions, thus, preventing contestations of principles and exercising power that only appeals to a chosen few. Some of the provisions of the Declaration of the Rights of Man would be gender equality, liberty without encroaching on the rights of others, right to property, security, resistance to oppression, sovereignty of the nation, laws based on the general will and etc. (Declaration of the Rights of Man, 1789). There are a lot of considerations of the Plan de Ayala in the light of the Declaration of the Rights of Man. First of all, Plan de Ayala was a movement that was surged because of the desire and need to end the tyranny and be able to redeem Mexico and its people from dictatorships. What was happening at this time was that the Mexican people who were led by Don Francisco I. Madero are now taking the law in their hands as the government or any political institution which is supposed to make sure the rights of man is served is already controlled by a single party which is headed by Madero. Aside from that, what rightly belongs to the people are not being served and moral laws are being crossed. To provide concise examples of Madero’s abuse, he clearly went against his commitment to push for revolution which he gloriously initiated to prosper the land. This is because of the fact that he gave in to corruption that defeats the purpose of the National Sovereignty and keeps it out of the equatio n; the numerous jailing and killings of revolutionary elements who helped him bag his presidency so all the power would be centered to him alone; the brute force done towards people who question or demand from him the fulfillment of the promises of the revolution, these people whom he called rebels to cover up to his brutality; and forcing more people into an alliance with him to form a new dictatorship where only their specific interests and rights are served (Womack, J., 1969). Thus, because of all the corruption of not only the people but also of the government and the other political institutions, the people of Mexico took initiative to solve anarchy and tyranny by seeking help from the remaining pro-Revolution chief justices to lead the movement. Aside from overthrowing Madero and Porfiro Diaz, an ally, they seek to regain what is rightful to each Mexican such as giving back the fields, timber, and water usurped by the landlords from citizens who actually have the titles to the se corresponding properties. However for the landlords who do not have documents to support their claim of property, the goods will still be confiscated from the corrupt leaders and will be nationalized - to be given to the victims of war, pensions for widows and orphans etc. (Womack, J., 1969). This course of act, overthrowing their leader is a right they can demand for as it is

An Assessment of British Airways Dispute and its Employee Relations Essay

An Assessment of British Airways Dispute and its Employee Relations - Essay Example British Airways concentrates mainly on its management approach which is considered to be inward-looking. Moreover, the company also focuses on the retention of its different routes and the outcome has been unsatisfied customers. Under the management of Bob Ayling's, British Airways faced industrial action, the employees were protesting against cost reduction which was aimed at improving the airline’s profitability. Subsequent to the earlier strikes and the cost reduction plan, the morale of workforce deteriorated resulting in continued unrest since then. In 2005, the union members protested against the decision to leave out a group of workers, replacing them with the agency staff when the company failed to renew their contract. The company incurred a lot of costs due to this and several passengers were disrupted. In October 2006, the company faced dispute which resulted from a check-in Christian worker putting on his faith’s visible symbol. In 2007, the cabin crew plann ed a strike action, they were protesting against the salary changes. Later it was withdrawn before it took off. According to Books Llc, (2010), British airways and the union Unite relations have continued to be turbulent, especially in 2009 and 2010. It manly resulted from the proposed changes of the cabin crew working conditions as the company was facing the global financial crisis. On December2009, a strike ballot was conducted regarding the working practices changes. It was supported by many especially the Christmas 2009, planned action. However, the industrial action was declared illegal by the court. On February, a re-ballot was held. The negotiations that were ongoing did not stop the strike action which took place in March. The company punished the staff involved through the withdrawal of the travel perks. Today the company is still faced by different challenges and has been trying to find a lasting solution to this. Competitive nature of the business and the rationale behind management proposals British airways is ranked as the ninth airline worldwide with regard to the total number of passengers it can carries. The airline network in the international market is considered to be the strongest. This is because as compared to other airlines, it operates in several destinations internationally. British airways has its base at London Heathrow which is the best location. This location is known to be central to the European air travel and is the leading business hub. The airline connections to various destinations globally are convenient and timely and this is the company’s main advantage of being situated at London Heathrow. Some of the company’s operations which are short haul have been moved to London Gatwick. This came up as a result of the increasing air traffic in Heathrow. In both the international and the domestic market, the company is faced with competition. The company’s main competitors in the domestic markets include airline s like Easy Jet which incur lower costs. In the international level, it has to face several giants which include Lufthansa and American Airlines. British airways main business in both the international and the domestic routes is to provide air services that are scheduled to passengers and cargo. The scheduled passenger service and cargo service of the company are separate divisions that operate in an independent way. The scheduled passenger services contribute a greater percentage to the company’

Business LAW Essay Example | Topics and Well Written Essays - 500 words - 2

Business LAW - Essay Example The plan by Johnny Jones to start a new Ethanol manufacturing plant is not a plan that has been included in the company’s registration statement and therefore such a plan should be prevented and suspended. Section 11 of the Securities Exchange act states that it will be deemed unlawful for any person who is a member of any securities exchange to make a transaction on such an exchange for his own account, that of an associated person or exercises an investment discretion. In this case Joan is acting in the capacity of a market maker in that she is a stock broker and therefore such a transaction can be seen been unlawful. Johnny also does not have any authorization to conduct such transactions in ethanol neither does he comply with the rules of the commission. A registration that is made under the exchange act entitles one to make periodic and current reports regarding the company. This is the duty to disclose which is made public for market evaluation of the specific company together with the way the company conducts the pricing of its securities (Smith, Washburne, & Pham). The Securities Act provides a penalty of not more than $10,000 upon conviction while the security exchange act provides that any person or anyone who becomes associated with someone who violates the requirements of the act or makes a false and misleading statement with regard to the act will be liable to a fine of $ 5,000,000 or imprisonment that does not exceed 20 years. In this case, Jonny Jones, Joan and Jake will be liable to such fines and even imprisonment for the violation of the Securities Act and the Securities Exchange Act. They do not have reports for their Ethanol manufacturing thus, they contravened the duty to disclose. Johnny also made a misleading statement to his secretary. Class action suits occur whereby so many plaintiffs sue the same defendant over the same

Programming Solution Proposal Essay Example for Free

Programming Solution Proposal Essay Computer programs can help us solve everyday issues that might seem impossible. Household budgeting is an issue that burdens many Americans. Every individual is ultimately responsible for managing his or her finances. Developing a computer program that can help individuals manage their budget will greatly improve their life quality. The program would have to follow the program development cycle model and use the modular approach. Identifying Budget Issues The biggest challenge that many American families are facing after the 2008 recession is managing a monthly budget adequately. The fact is that many families increased their debt by borrowing more than their allocated budget. Americans need to learn to live base on how much they earn. Our first reaction, when in debt, would be to make up excuses as to why we are in that situation. Some of us will even try to blame relatives or credit card companies when faced with excessive debt. It is families, who do not budget properly, that end up losing their homes and vehicles to banks or lenders (msn, 2009). Who is Responsible? The task of managing your budget according to your earnings is a decision and responsibility that is ultimately yours. The first step to take when budgeting is to acknowledge your debt problem and stop finding justifications for it. The problem can be excessively stressful and it is recommended to seek assistance through friends, family, or even better from an organization that guides people through debt reduction. A non-profit organization, such as the National Foundation for Credit Counseling, will probably be the best option. To start getting a handle of the problem, one must establish a number of how much is owed (msn, 2009). Developing a Program Technology, at present day, is an important tool that can be used to our advantage to solve almost any issue. Many families that might be facing budgeting and even foreclosure issues might not be aware that such tools exist. The process of creating a computer program that will help us budget our monthly income can greatly improve our quality of life. Such program must follow the program development cycle and contain the three main components of a computer program; input, process, and output (Venit Drake, 2009). Program Development Cycle The first step of the program development cycle is to analyze the problem. We need to fully understand the problem that needs to be solved. We also need to analyze which information is available to us. The initial information available to us is our monthly net pay, and our monthly economic obligations. We also need to establish our desired output, establishing a budget, and determine how our known information will help us achieve those results. At this point we might also become aware of information that is not included but is necessary in order to identify the problem properly. Such information may include unexpected expenses, depositing money into a savings account, etc. (Venit Drake, 2009). The next step of the cycle is designing a program to solve the problem. The designing step of the program development cycle will yield a flowchart that will outline how the actual program is executed based on the known variables. The flowchart will include a starting point, inputs, assignments, If conditions, loops, outputs, and an ending point. The evaluation of each step of the program development cycle might yield additional subtasks that might need to be added to the original flowchart. This step also involves writing an algorithm in pseudocodes which will instruct the program on what to do. The last two steps of the cycle involve writing the pseudocode statements in program code. The program code will depend on which computer language is chosen. Finally the program needs to be executed to determine if it runs properly. A re-evaluation of the program might be needed if the program does not execute properly (Venit Drake, 2009). The goal of the program is to aid the average household to adequately manage a budget. Modular Approach The modular approach that will be taken to create this budgeting program will ensure the creation of the proper program to solve the issue. The approach will first consider the major tasks that need to be accomplished. A module will be created for each task in the program. The tasks can later be broken down into sub-tasks as deemed necessary by the programmer. These sub-tasks will then be assigned sub-modules. The amount of sub-tasks is determined by the complexity of the problem and how many are needed to solve the problem. The purpose of breaking down tasks is to make the program much easier and simpler. The model that is used to break down tasks is called the top-down design (Venit Drake, 2009). Conclusion Developing a computer program that can help individuals manage their budget will greatly improve their life quality.

Advantages and Disadvantages of Positivism

Advantages and Disadvantages of Positivism Q. Discuss the advantages, strengths, disadvantages and weaknesses of a  positivist approach to the social sciences. The profusion of use and multifariousness of meaning of the word positivism results in a need for any essay on the subject to first give its own precise definition for its use of the term, distinguishing its particular context from its use in other contexts. The term positivism, first coined by the philosopher Auguste Comte in the nineteenth-century, was first originally confined to the boundaries of philosophy and natural science; by the present, the term has spread its meaning to cover fields as diverse as law, political theory, the social sciences, philosophy and even literature. In all of these fields the dictionary definition of positivism as ‘. . . a system recognizing only that which can be scientifically verified or logically proved, and therefore rejecting metaphysics and theism’ (Oxford, 1989: pp. 385-386) remains broadly true of most of its uses, though it does little to reveal the subtle distinctions of use of the word positivism in each of these disciplines. For instance, legal positivism is ‘. . . a view which, in contrast to the natural law view, claims that a legal system can be defined independently of evaluative terms or propositions is the view that in law’ (Hugh-Jones, S. Laidlaw, J, 2000: p88); in literature positivism refers to a specific period of Polish literature where writers were inspired by the nascent achievements of science and technology; and in philosophy the term logical positivism meant the scientific investigation of the philosophy of language — as in writers such as Wittgenstein. All in all then, the term positivism has an umbrella use designated by the dictionary definition, but then has several further and more individualistic uses depending upon the context in which it appears. ‘Positivism is the view that serious scientific inquiry should not search for ultimate causes deriving from some outside source but must confine itself to the study of relations existing between facts which are directly accessible to observation’ (Hugh-Jones, S. Laidlaw, J: 2000: p.3) The definition of positivism chosen for use in this essay, its particular domain being the social sciences, is that stated above by Hugh-Jones and Laidlaw. According to this version of positivism, data gathered from sense perceptions is the only possible data that may be used as a foundation for knowledge and thought. Hence, all data and phenomena taken from beyond sense perceptions or the properties of observable things is banished — thuds a priori metaphysics and theology dismissed in toto. Science alone sets the perimeters for human knowledge, and, accordingly, positivism maintains the expectation that science will ultimately attain to solve all human problems. As such, a social scientific definition of positivism regards the research of social scientists as identical in importance to that of natural scientists; that is, social scientists, like natural scientists, employ theories and explanations for phenomena, inferred from sense data for the purpose of social benefit. Wit h respect to political science as a social science Popper thus says ‘We get the particular definition of one of the social sciences — political science — which tries to separate the subject from the values we apply to it, and argues that it is possible to develop value-free knowledge’ (Popper, 1983: p. 75). This quotation shows the extent to which one particular social science’s use of the term positivism has mutated from its general umbrella use. For the purposes of this essay, positivism will be regarded as having four essential characteristics (King, 1994: p. 204). (1) It is concrned with the search for the unification of scientific method, that is, with the notion that logic and inquiry are universal principles extending across all scientific domains. (2) That the ultimate end of scientific inquiry is to gives explanations of social phenomenon and to make predictions about their behaviour as according to discernable laws of society. Thus positivism in the social sciences seeks also to develop a ‘general law of social understanding’, by discovering necessary and sufficient conditions for any phenomenon. (3) Positivism maintains that social scientific knowledge must always be subject to proof through empirical experimentation. All subjects of reaseach and investigation in the social sciences should be based upon observations derived from sense-perceptions. (4) Social sciences must seek to free themselves of valu e-judgements as far as possible, and of moral, political, and religion ideas that might contaminate their research. Thus, in short: social sciences must seek to dicover universal conditions behind social phenomena;all social scientific empirical statements must be asolute truthes which are true at all times and true in all places; finally, research can proved only by empirical experimentation. In There Is More Than One Way To Do Political Science Marsh Smith (2001), while debating whether the social sciences might legitimately have both a positivist and realist approach to science, argue that one of the principal strengths of positivism is that it is ‘foundationalist’: that is ‘. . . in ontological terms it argues that there is a ‘‘real world’’ out there, that it is independent of an agent’s knowledge of it’ and that ‘. . . it is possible, using the proper ‘‘research methods’’ for an observer to discover these real relationships between social phenomenon’ (Marsh Smith, 2001: p. 529). Thus the great strength and advantage of a positivist approach to the social sciences is that it grounds anthropology, sociology, political science and so on upon a hard and definite ‘foundation’ of empirically testable data, and makes theories out of this data from which absolute laws of social behaviour may be attained. A second distinct advantage then of positivism is that it permits an analysis of the causal relationships between phenomena. Positivism thus allows the social sciences to make certain predictions about the phenomenal world. Thus Dowding states ‘. . . all good political scientists produce models with definite predictions . . . which they can then test one way or another against data gathered from the actual world’ (Dowding, 2001: p. 92). A chief strength then of a positivistic approach, is that it brings to the social sciences the desire to emulate the excellence of the natural sciences in respect of their rigorous experimentation, precisely stated hypotheses, definite laws, and thus prediction of behaviour. By approaching its investigations thus, social scientists attain a high level of accuracy in their results and in their predictions, and thus come closer to a total description of the behaviour of social phenomenon. By approa ching the social sciences from a positivist position, social scientists are able to cut away from existing ‘knowledge’ many prejudices, suppositions, superstitions and other non-scientific opinions that have gathered about these social phenomena (Marsh Smith, 2001). In other words, positivism, by declaring valid only those things which conform to its vigorous standards of investigation, strips social phenomenon of their perceived nature and reveals them as they really are. A second key advantage of taking a positivist approach to the social sciences is that such a move solidly roots the social sciences in the accomplishments of the natural sciences over the past four hundred years. Early positivists like Comte, Spencer and Saint-Simon understood their theory and work as something growing directly out of the experimental and theoretical achievements of the great natural scientists like Newton, Spinoza, Darwin and others. Comte knew that the natural sciences and natural scientists, were essentially positivist: that is, they appealed to the perception and measurement of objective sense-data from which to make experiments, analyze results and make theory, predictions and laws. Comte and the other early positivists thus understood their work as an act of ‘making explicit’ the theory which natural scientists had adhered to for centuries. When, in the twentieth-century, social positivists like Ernst Laas, Friedrich Jodl and Eugen Duhring began to establish the theoretical and experimental parameters of the social sciences, they also understood their work as a branch of the natural sciences and as a continuation of its discoveries. Anthropologists, sociologists, social scientists of the early twentieth-century faced a choice: they could orientate their subjects within the sphere of natural science and its immense harvest of the past two decades, or they could orientate it in the sphere of theology and the liberal arts which had dominated all human history before the advent of natural science. Laas, Jodl, Duhring and later Marsh, Smith and others have all agreed that the social sciences must be built upon the platform established by the natural sciences. These sciences have been the predominant intellectual authority for Western Europe for nearly four hundred years, and social scientists think that the positivist approach to the natural sciences offers greater objectivity, certainty of prediction, and deeper insight into thei r subjects than could achieved by any other method of inquiry. Further, the allegiance of the social sciences to the natural sciences, through a shared conviction in the positivist philosophy, means that the social sciences can constantly draw upon the fund of new empirical material daily unearthed by these natural sciences. In other words: if the social sciences have an exchange of knowledge between themselves and the natural sciences, then every refinement of experimental method, theory, or analysis achieved by the natural sciences may be immediately seized upon and utilized by the social sciences also. And, vice-versa, this interchange allows the social sciences to more freely disseminate their discoveries within the world of the natural sciences. Moreover, by sharing a positivist philosophy with the natural sciences, the social sciences may draw from its authority in the presentation of their results to the wider scientific and academic community. That is, the employment of positivism by the social sciences, dispels and neutralizes the accus ations from some quarters of the scientific and outside world, for instance those of Karl Popper, that such sciences are ‘pseudo-sciences’. This claim can hold no weight if it is seen that the natural and social sciences share alike the same methodology and principles of operation. Nonetheless, it should be made clear that whilst the social sciences derive authority and knowledge from the natural sciences, that they do not depend upon it exclusively for authority. Indeed, the social sciences have made their own refinements to positivism, and thus their methods of experimentation and analysis, quite independently of those achieved in the natural sciences. The social sciences have adapted the positivism they received from the social sciences to conform to their own empirical material and the idiosyncratic and diverse domains encountered in societies and the human world. In short, the social sciences have moulded positivism to the world of empirical human affairs, thus ent ering a territory that the natural sciences had previously not trodden. Historically, perhaps the greatest weakness and hence disadvantage of positivism generally, and with respect to the social sciences in particular, has been its insistence upon methodological absoluteness. Since the time of positivism’s foundation in the philosophy of Auguste Comte, positivists have persistently sought to use its scientific methods to explain every conceivable aspect of social phenomenon; that is, they have wanted to observe an object in its totality, tracing its entire phenomenological casuistry, its material composition, and thus produce a absolute theory of knowledge about that phenomenon. According to this scientific philosophy positivism must produce absolute laws to describe the behaviour and nature of phenomenal objects. The naivety of this search for the perfection of methodology and absoluteness of social scientific laws was exposed in the second half of the twentieth century, firstly by the advent of post-modernism (Popper, 1989: p.109-128), which sho wed the epistemological difficulties — impossibilities? — of extending science to such extreme levels; secondly, positivism’s applicability in all instances was increasingly undermined by the new theories of social scientists themselves. The various discoveries of anthropology, sociology, political science and other social sciences led researchers to an ever clearer conclusion: the phenomena of social science are far too sophisticated and involve the intimate interaction of too many separate objects, people and processes to be scientifically observed in their totality. Sociologists for instance, in their investigations into the mechanisms of the smallest of social units, the family, soon realized that no absolute and all-encompassing laws could be applied to the behaviour of these units (Gerrad, 1969: pp. 201-212); the great complexity coming from the need for the axioms and paradigms which are true of one family unit must, according to pure positivism, be shown to be true of all family units in all places and at all times. Pure positivism states that the laws of social science are of the same type and significance as the laws of physics, biology and chemistry; but for these laws to attain this equality, the laws of social science must be easily expressible and as rigorously testable as those of the natural sciences. The difficulty of attaining such equality is easily demonstrated by Gerrard’s (Gerrard, 1969) experiments, where he discusses the complexity of social issues involved in a four member family unit in America, and then postulates the near impossibility of scientifically demonstrating that family units in Northern France, in Thailand, in Hawaii and in all other places can be shown to obey the same exact rules as those affecting the family in America. Thus social scientists from the 1950’s onwards, confronted with the sheer vastness of ethnic, racial and community diversity, began to question the possibility of producing social laws that would be universally and ubiquitously binding. And in 2006 when even natural scientists have no certainties even about the exact behaviour and nature of a single atom; how can social scientists hope to prove laws for something as complex as a city? Another weakness of extreme positivism has been its inability to accurately prove its hypotheses through empirical experiments (Popper, 1983: p. 12 also: Dowding, 1995: p. 138). Whereas experimentation in the natural sciences usually involves the investigation of inanimate or relatively simple objects such as metals, stars, chemicals and so, these having the same properties constantly, in contrast, social phenomenon — people, communities, organizations etc., — are animate and are compositions of vast complexly intertwining feelings, emotions, thoughts, volitions, passions, motives, associations and so on. Thus, to undertake a social experiment, a social scientist has to be sure that he can separate the single mental or behavioural element, say ‘a criminal tendency’ that he wants to investigate, and then to exclude or control the influence of the other mental and social factors that will otherwise affect the accuracy of the experiment. In many instances suc h exclusion is nearly impossible to the degree of purity demanded by extreme positivists; a human being cannot be put in a test-tube or a vacuum and so shielded from external influences in the way that magnesium or atoms can. Thus social scientists have become ever more conscious that a major limitation of the positivist approach in respect to their discipline is its insistence upon perfect conditions for experimentation and for the accuracy of hypotheses and predictions (Dowding, 1995). Further, other discoveries in the social sciences have begun to place an ever greater emphasis upon the life of the individual and upon subjective experiences as vital factors in the constituency of societies (Marsh Furlong, 2002). The hermeneutic or ‘interpretive’ approach has come to assume ever greater importance within the social sciences, setting up for itself an area of investigation of phenomenon quite different from positivism, and therefore undermining the legitimacy of positivism’s claims to describe the totality of social phenomenon. Positivism is, according to this view, the outcome of a particular culture and particular history (Western European); what legitimacy then does it have to proclaim its results as of universal validity, as it must, to meet its own standards of scientific investigation? Moreover, social scientists themselves bring to their experiments their own subjective experiences, their own thoughts, volitions, prejudices etc., and these all affect experimentation and thus the security of results — just as surely do these things in the subjects of analysis. Thus David Marsh and Martin Smith have stated, in their powerful metaphor derived from Marsh’s earlier article, that ‘In the social sciences . . . subjective ontological and epistemological positions should not be treated like a pullover that can be ‘‘put on’’ when we are addressing such philosophical issues and ‘‘taken off’’ when we are doing research’ (Marsh Smith, 2005: p.531). That is, they should not be treated as a ‘pullover’, as temporary measure, as they have been by positivists to date. In the final analysis, it seems clear that neither the extreme positivism once advocated in the wake of Auguste Comte’s first philosophical writings, nor extreme anti-positivism nor anti-foundationalist positions as have recently been taken by some hermeneutists and realists, can lead to significant future progress in the social sciences. The chief strength and advantage of a positivist approach is the vigorous process of setting hypotheses, of empirical experimentation to test these hypotheses, of deep analysis to measure the results, and then the ability to codify the results in a set of laws and predictions. Claiming for themselves, in this sense, a parallel certainty of laws and predictions as and laws demanded by the natural sciences, positivism reveals to the social sciences phenomenal objects as they really are — as they are when stripped of superstitions, fallacious theories, prejudice and so on. Positivism demands a definite residue of facts and ‘truthsâ €™ that are universally applicable to social groups and communities irregardless of time, place or environment. In striving so vigorously for such ideals, positivism gives the social sciences a high degree of authority and respectability within the wider scientific and academic community as a whole. Further, a positivist approach in the social sciences affords a ready means of comparison and exchange of knowledge between other disciplines such law, philosophy, literature and so that employ positivism also. Indeed, in seminal respects, such is the importance of positivism for the social sciences that it is difficult to see how they could justify being ‘sciences’ without it. The two principal disadvantages of a positivist application to the social sciences are these: firstly, that its search for ideal and perfect standards of scientific methodology and analysis are too unrealistic when set beside the extreme complexity of social phenomenon; the second weakness, is positivism’s lack of empathy and consideration of the subjective, individual and hermeneutic aspects of social phenomenon. Dealing with the first objection, critics of positivism argue that it cannot — working as it does in the outside world, in cities and in companies, in villages and mass organizations — attain the same standards of empirical excellence, either in experimentation or in verification of results, as can natural scientists working in the controlled conditions of a laboratory and deriving principles mostly from inanimate matter of slighter sophistication than human beings. Moreover, social scientists have a nearly insuperable difficulty in codifying laws of so cial phenomena with the precision that physics or chemistry allow for material phenomena. Thus positivism in the social sciences attains a lower level of prediction and accuracy with respect to the phenomenon it observes, than do the natural sciences. The second major weakness of a positivist application is its failure to take sufficient account of the subjectivity of individual life and to interpret the meaning of that phenomenon for the subject and the community of the subject. On these matters positivism has nearly nothing to say, and thus it is barred from a whole hemisphere of human social experience. As the first sentence of this conclusion suggested: neither an extreme positivist not an extreme subjective or hermeneutic attitude can dominate the future of the social sciences. Rather, social scientists must learn to join positivism with subjectivism, thus fusing the two halves of social phenomenal experience. If positivism can be brought into union with the subjective in the social sciences, and if positivists can learn to tolerate something less than perfection in their methodological approach, then positivism must still be said to have a large contribution to make to the future of social science. In might be said then, in our final words, that positivism is simultaneously an advantage and disadvantage for the social sciences; whether one or other of these qualities is dominant remains to be seen.

Project Planning And Challenges Facing Planners Construction Essay

Project Planning And Challenges Facing Planners Construction Essay This chapter will review the literature which has been used for this dissertation. A number of important aspects will be covered, including an overview of Construction Planning as well as determining what challenges are faced on a daily basis by construction planners. This chapter will also review research relating to Planning techniques used and software packages available within the Construction industry. 2.2 Construction Project Planning Project Management can be seen as the application of tools and techniques utilised to guide the use of resources towards achieving an intricate task within the constraints of time, cost and quality. From conception to completion, a mixture of these tools techniques is necessary to fit the task environment and project life cycle. (Oisen 1970). The British Standard for project management (BS6079 1996) defined project management as, The planning, monitoring and control of all aspects of a project and the motivation of all those involved in it to achieve the project objectives on time and to the specified cost, quality and performance. The UK association of Project Management (APM) have produced a UK body of knowledge UK (BoK) which also provides a definition for project management as The planning, organisation, monitoring and control of all aspects of a project and the motivation of all involved to achieve the project objectives safely and within agreed time, cost and performance criteria. The project manager is the single point of responsibility for achieving this. Project Management as we know today has evolved in order to plan, coordinate and control the complex and diverse activities of modern industrial, commercial and management change projects. (Lock 2007) To allow for effective planning and control of projects, a requirement for systematic and logical methods should be applied along with proven techniques, thus ensuring a successful project outcome for all concerned parties, particularly the client. Without planning it is difficult to envisage the successful conclusion of any project or the effective control of time, money or resources. Planning is also essential in order to deal with construction risks and devise safe working methods. (Cooke 2008) Project Planning is defined as the establishment of a set of directions in sufficient detail to tell the project team exactly what must be done, when it must be done and what resources to use in order to produce the deliverables of the project successfully. (Zwikael 2008). Construction planning is an essential and challenging activity in the management and implementation of construction projects. It occupies the choice of technology, the description of work tasks, the estimation of the necessary resources and durations for individual tasks, and the identification of any interactions among the different work tasks. Hendrickson (1998) believes a good construction plan is the basis for developing the budget and the schedule for work. It is therefore common to adopt a conspicuous importance on either cost control or on schedule control as illustrated in Figure 2.1. Fig 2.1 (Hendrickson. 1998) Walker (2007) considers that by having a project schedule to work to and sticking to it, you will well be on your way to delivering successful projects. This would be dependant on effective communication and efficiency at all stages of the project and with an aim to reducing risk, time and cost. 2.3 The Construction Planner Construction project planning is receiving growing attention as the limitations of formal deterministic planning are becoming more widely recognised. (Winch, Kelsey 2004). There is growing concern over the failure of construction planning to achieve its goals in spite of the considerable resources allocated to it. Deficient planning techniques are commonly blamed for this state. (Laufer, Tucker, 1987) There has been considerable debate over the last decade or so on the effectiveness of construction project planning. However, there is remarkably little research into what construction project planners actually do. Laufer and Tucker provide a critique of construction planning. They protest that:- the planning and evaluation of planning processes are non-existent there is over-emphasis on critical path methods planners lack construction experience planners have poor information gathering methods planning is control-oriented instead of action-oriented Plans are been poorly presented with overly-complex information. In a subsequent paper (1994) Laufer and his colleagues look at the definition and allocation of planning work. They found that there was no clear system at work and planning was done in a multiplicity of ways. They call for the process to be properly co-ordinated by a single individual who will own the planning process and improve communication. Winch and Kelsey (2005) believe the specialist planner has the time to do the work but incomplete practical knowledge. The line manager has the practical knowledge but does not have the quality time to carry out the task. The specialist planner has better strategic decision-making skills than the short-term decision-making focus of the line manager. They then go on to say Line managers see the delegation of key decision-making to another as a threat to their position. These problems are confirmed in Laufer (1992) wider project management study and can result in: The planner preparing a plan which has incomplete information and in-adequate decision making authority. The line manager treating such plans as merely an irrelevant forecast prepared by another. Allen Smallwood (2008) believe Construction planners and the role they perform are little understood both within the construction industry and the wider environment where construction has a daily impact. Planning occupies a central position in the functions of the manager. His responsibilities may vary with organisational philosophy and contingency but planning invariably remains an essential ingredient of his duties. (Steiner, 1979). Much Research and Development effort has been made during the last three decades but progress with techniques has not removed the dissatisfaction with the application and results of construction planning (Choudhury 1981, Mason 1984, Morton 1983). Effective construction planning demands that it is carried out by competent and experienced personnel. While the estimator must remain in charge or pricing the work, most contracts, today, are too complex for the estimator to handle the technical content of pre-tender appraisal. It is here that the construction planner has a major function. 2.4 Planning Techniques Most planning techniques aim to express the work to be done, to a time-scale; some also include resources, and perhaps cost and value. In simple terms, they intend to help control time and cost. The other major factor in project control, quality, is controlled by its own family of control techniques; and quality is related to time and cost through the skill and judgement of the project management team. Neale (1989) believes the major components of planning techniques are: Activities: literally, being busy, expending energy, consuming resources, taking time; in construction planning, this means a job to be done; for example preparing a drawing, an order to be places, a hole to be dug, bricks to be laid in a wall, a flow of water to be diverted. Activity durations: the time required for the completion of each activity Project time-scale: the time structure of the project; it is usual to give each week in the project a number (this makes calculation easier), and these then have to be related to calendar dates, holidays, etc. Event: an occurrence at a specific point in time; for example, the granting of planning consent, of the start or end of a traffic diversion. Work method: the plan must be expressed in some logical way, indicating the sequence of operations, and which activities and events are interrelated; this may be implicit (as with bar charts) or exlicit (in network analysis, where work method is usually called logic.) Resources: often called the four Ms (men, machines, materials and money) but can include overheads (for example, site accommodation), and even such essentials as managerial skill. Costs: what the work has or will cost, often derived directly from the unit costs of the individual resources. Value: what has or can be earned by payment for work done derived from the bill of quantities, the estimate or an internal budget. The calculation of value-to-date can be used as an overall measure of project progress. The following four techniques are often used in construction planning; Bar charts, Network analysis, Line-of-balance Linear programmes. 2.4.1 The bar chart/ Gantt Chart Drafting of a bar chart is popular because it produces results which are easy to understand and not too searching of the planner. Its use is limited to planning straightforward work with simple relationships between the activities. This graphical technique still forms the foundation for most resource scheduling. Its major drawback is that even minor deviations from it require extensive redrafting as a result making it more difficult to having to hand a contemporaneous bar chart that is a reliable indicator of future events. The main features of the bar chart are as follows: The activities are listed on the vertical axis Time is shown on the horizontal axis. This may be an appropriate time unit, such as months or days. Each bar is divided horizontally into two, with the top half representing when the activity is planned to take place, and the bottom shared in, as proportions of the activity are completed. A vertical movable marker line indicates the current time, thus enabling the observer to note if any activities are behind programme, and to what extent. Refer to Figure 2.2 for additional information. Figure 2.2 Typical bar chart The format of the bar chart presumes that the end user (client) can involve the same judgment that was in the mind of the planner when he was compiling it. In highly repetitive or simple work it can be implied that the users will better understand the thought process of the planner. However as project complexity increases the users ability to monitor the project in relation to the programme is reduced unless it is understood: What work is important to progress? Of the activities currently behind programme what, if any, effect do they have on overall progress? On the contrary, if most of the actual work is ahead of programme, does this mean that the current prediction is that the project will be complete in advance of the targeted completion date? The answer is definitely not an automatic yes. To provide an informed response, an understanding of the relationships between programme activities is crucial. Neale (1989) consider these deceivingly simple questions contradict issues which are at the heart of many construction disputes, namely considerations for extension of time. 2.4.2 Network Analysis Unlike a bar chart, activities are not shown on an axis of time. What the network portrays is the logical relationship between activities. Network analysis is a powerful, logical and analytical technique. It is most effective when used for complicated projects, especially those with external constraints and complex interrelationships. The technique is based on drawing the logical relationships between construction operations, and from an analysis of the relative durations, establishing which operations have the most crucial effect on the project duration. It can be drawn in a number of ways, the most well-known in the UK being the arrow diagram. Figure 2.3 Network diagram The technique is sometimes known as the critical path method (CPM), and critical path analysis (CPA). A version which incorporates a statistical method for calculating the probability that a project will be completed on a specific date is called the programme evaluation and review technique. (PERT) The identification of a critical path focuses the attention of the individuals managing the project and highlights to clients and their advisors the tasks that require to be particularly well managed with regard to time. The duration of critical path represents the shortest duration in which the project can be completed. Delays to activities on the critical path transmit directly through to extend the project completion date. This provides advanced warning of the pending delay to completion and enables the contractor (or employer) to invoke recovery action at a useful point in time rather than waiting until it is manifestly obvious that the completion date is threatened. If the employer or his Architect/Engineer (A/E) instructs additional work which affects the activities on the critical path then the contractor has grounds for a claim for an extension of time. The term critical path is widely used in the construction industry; what is not fully appreciated is how easily the critical path can change. Figure 2.4 Network diagram showing critical path Network analysis has a good and inclusive logical basis, lends itself easily to computer processing, and can be used as an effective control tool. These exceptional characteristics are also known to be its principal weakness as it is easier for the planner to be drawn into a level of planning and analysis that is much to detailed and advanced for most construction projects. 2.4.3 Line of Balance Line of balance is a specialised technique used for repetitive work. It derived from the manufacturing industry and has been found to be effective in planning work truly repetitive. Examples of success applications include planning the construction of identical floors in high rise construction, and large housing developments. Line of balance has been found to be difficult to use on projects which have a high demand for trades or operations to construct each identical unit. The problems arise not from the technique itself, but from the difficult of showing all the information on one chart, particularly when using the technique to monitor progress. When used to plan, it can be an excellent means of relating resources, activity durations and the general pace of work on site. Neale (1989). Illingworth (1993) considers the line of balance approach has largely fallen out of use in todays industry due to the fact it was designed primarily for housing and did not readily provide clear visual appreciation of the situation at a glance. Figure 2.5 -Typical line of balance diagram 2.4.4 Linear Programme (or time-chainage chart) Linear programming is a specialised technique for linear work. This is a basic tool of UK road contractors. Other successful applications include the construction of a large canal in a developing country, and it is especially useful in tunnelling. Illingworth (1993). Similar to line of balance, this is a simple two- dimensional graphical technique and can show clearly only a limited amount of information and limited degree of complexity. Figure 2.6 Linear Programme (Neale 1989) 2.5 Which technique? The experienced planner in construction needs to be aware of the techniques available, together with the value of each, both in the planning analysis role and how then can be applied to give effective control and communication to management on site. Illingworth (1993). Like any other professional, the planner has to select the right tool for the job. To make the correct decision, it is therefore a requirement to examine what is wanted in a particular situation programme. Illingworth (1993) believes the main points of this choice are as follows: Does the method aid initial analysis of the situation and especially in establishing the best sequence of events? Are deficiencies in progress shown up as the work proceeds? Can visiting management obtain and immediate view of the contract situation on arrival on site? With the preponderance of subcontractors on site today, does the programme method give assistance in cash flow control? According to Illingworth, from these questions it is unlikely to be the answer to all desires. Therefore it is said to be better to consider the situation in two stages tender planning on the one hand and the operational planning after the contract has been won, on the other. 2.6 Planning Practice In order to explore further the reality of construction project planning semi-structured interviews were conducted between July and December 2000 with 18 experienced planners from five leading UK construction firms. Most of the planners interviewed were currently involved in planning at the tender stage including assembly and presentation of the tender documentation. About half of those were also involved at the tender/ pre-construction stage. Only a few were further involved during the site works. (Refer to figure 2.7). Generally, although a number of the interviewed planners had on-site experience the typical pattern is that a planner works either at the pre-tender, pre-execution stages or on site but not simultaneously. The exceptions tend to be where planners work for some time on a single large project. In such cases it may make sense (from the employers point of view) for their work to carry on to the execution stage. Figure 2.7 Planning Practice, G.M Winch and J.Kelsey 2.7 Programming Considerations at the Tender Stage Upon receipt of tender documentation, the contractor will appoint human resources tasked with compiling a tender submission based upon the tender enquiry. One of the main individual in this team is the person accountable for producing the tender programme, the construction planner. Whether or not the contractual terms require a programme to be produced or not should be irrelevant at this stage. The tender programme is an important document produced by the contractor which is used for measuring many risk and cost related issues. In particular, the assessment of cost of the contractors time related preliminary items as drawn off the content of the tender programme. For example, the anticipated on site durations for different members of staff, periods of scaffold hire and duration for site accommodation are items that cannot be priced by the estimator without reference to the tender programme. When compiling the tender programme, the construction planner must incorporate the information supplied with the enquiry noting any specified constraints contained in either the contract bills, specification or drawings. Conflict between documents often exists and a view had to be taken on how to proceed. Clarification may be sought from the employer or his agents, assumptions made and stated along with the submission or the conflict may be ignored and the information that best suits the contractor is assumed without qualification or statement. It is accepted in the industry that many bids are won or lost on the programme duration alone. This happens frequently where a bill of quantities is being priced and the experienced contractors tend towards similar prime cost for similar items. On completion of reviewing tender documents, drawings, specification and bills, which may be typically done over a period of one or two weeks, the construction planner will establish the work scope which will be addressed in the creation of a tender programme. The main objective is to be aware of the specified period for construction. Additional to the completed programme should be a schedule of resources which corresponds with the programme and a series of method statements signifying construction techniques and equipment to be employed in carrying out the work. 2.8 Programming on Site When the contract is won, the site planning is equally important. It is usually at this point that the site manager will have his first chance to examine the methods on which the job was priced. What is important to recognise, at this point, is that planning must be seen as an addition to management. Thus the site manager must have the right to question the planning methods on which the contract was priced. To do so, site managers require the technical expertise to assess what has been put forward. In so doing, the manager concerned must, for his part, accept that if he wants to change the method from that in the priced tender, he must demonstrate that his alternative is obviously cheaper, or at least as cheap, as that priced in the tender submission. When final agreement has been reached, the planning function can be established on site and develop the final method to be adopted. This, in turn, will lead to the contract master programme and such subsidiary programmes as may be necessary. On completion of all methods being confirmed the construction planner continues to have a significant role on site. First, in developing control and short-term programmes for all organisations contributing to the contract under the main or managing contractor. Second, the construction planners cherished knowledge of how the work was originally planned makes him uniquely placed to examine the potential consequences of alterations to what has to be built. In this area he is a valuable source of information to the site quantity surveyor when assessing where possible contractural claims may arise. Today, with the ever increasing use of trade sub-contractors as well as specialist service contractors, the experienced construction planner has the option of either seeing the role as satisfying its own right, or as an essential ingredient of experience for becoming a successful site manager. Illingworth (1993). 2.9 Purpose of a Programme The values applicable to the mechanics of construction planning are similar whether you are a main contractor submitting a quotation to an employer, a sub-contractor quoting to the main contractor, or even a construction manager providing programme assist to an employer. Common principles apply when compiling a construction programme, that of methodical analysis. The contractors construction programme is an important common reference. It shows how the planner they have interpreted the contract documents and other information from which the statement of intent for construction is issued. As the key programme for the construction work, its content is of the utmost significance to all parties charged with handing over to the employer a building fit for purpose within the contract time stated. A well prepared programme is vital to every construction project. Many activities have to be cautiously defined and given a time scale, and it necessary not only to assemble and list the information but also to display it visually in terms of the contracts objectives and the calendar. The working sequences and the relationships between individual activities must be clearly conveyed in this visual presentation. The Chartered Institute of Building (2001). They consider the construction programme to be a statement of intended actions, which when properly used provides management with its plan of campaign. It should communicate with ease, providing the common reference for the timing of all activities related to the project. 2.10 Construction Planning Software An expert planner faced with the task of producing and analysing a network for a project containing only few activities will undoubtedly produce the fastest results by drawing a freehand arrow diagram and analysing it mentally. Lock (2007). He believes it is likely to take longer when using a computer because of the formalities needed to set up the new project files in the system and enter the data. David Arditi and Ann Rackas compiled a short report in May of 1986 with an aim in ascertaining the need for computer software to assist is construction planning and scheduling. This report concluded, the individual needs of a given construction company are the primary reasons for choosing a particular software package. For example, one of the participating general contractors basic requirements was to have a 40-character activity description field: a particularly individual need. They continued to suggest if a program is to survive the inevitable shakeout that occurs after the initial development and interest have peaked; it must offer the features and capacities that are required by the user. In addition, every effort should be made to make computers less mysterious and confusing as they will be dealing with the construction market. Today there are many planning software packages available to the construction industry. Asta Powerproject, Microsoft Project, Primavera, PERT Master to name a few. Each package is commonly suited to the individual needs of the planner. Some programs present a blank Gantt chart on the screen as soon as they are booted up, and it is apparent to the user that task data can be typed in immediately. Most programs allow the user/ planner to establish project durations, critical path network, allocate resources, assign costs to tasks and monitor progress throughout the project. As a result, most construction planning professionals use such packages daily. 2.11 Construction Planning Challenges Lock (2007) considers anyone planning a project of significant size will soon find out that there are a number of factors, both inside and outside the project organisation that can have an effect on the planners intentions. These are as follows: 2.11.1 External Factors Figure 2.8 External Factors (Lock, 2007) All projects are subject to risk, many of which can have an enormous impact on plans. Lock (2007) deems the following are just four from the long catalogue of happenings that can be categorised as Acts of God: An earthquake devastates a project organisations headquarters. A hurricane and flood put a project site under a metre of water and delay the start or ruin the work in progress. An influenza epidemic puts half the project workforce out of action. (Swine flu outbreak 2008 recorded thousands of people off work for over 5 days.) The project manager (a keen golfer) is struck by lightning. The national government can play an important part on the smooth running of a project. E.g. the project could be government-funded and is cancelled or abandoned through a political decision. Lock (2007) also considers less immediate concerns which are the wider and longer-term economic consequences of government policy leading to downscaling of projects, delays and cancellations in all sectors of industry. Decisions made outside the project team can also have an affect on many characteristics of planning. E.g. a decision is made at directorate level to carry out a project in a different company within the group from that initially anticipated or a strategic decision is made to cut short all new staff recruitment resulting in a lower number of available resources formerly expected to be available for projects. 2.11.2 Working Factors Figure 2.9 Working Factors Lock (2007) These are items which are likely to affect the project team on a daily basis. Examples include availability of resources, materials etc. People are believed to be a construction organisations greatest resource. Construction operations depend on the knowledge and skills of people planning and executing the work. Muir (2005.) Research has been carried out to reveal that the construction industry is typically viewed as being one of the least attractive industries in which to work. Safety plays an important part in the running of a project. Construction by nature is unsurprisingly dangerous with a high degree of hazard and risk. The Health Safety Executive believe each year: Over 1 million injuries and 2.3 million cases of ill-health are experienced by workers; Around 40 million working days are to lost; and Over 25000 individuals are forced to give up work because of injury or ill health. These cost British employers on average  £3.3 to  £6.5 billion each year. Most organisations are oblivious of these figures and are often astonished to find out what the actual costs are. Recent HSE Examples (2009) An injury to a worker using an unguarded drill cost a small engineering company  £45,000. And that was not all. The managing director was prosecuted from which two employees had to be made redundant to keep the company afloat. At the other end of the scale the Piper Alpha explosion killed 167 people and incurred estimated costs of over  £2 billion. Accidents in construction can account for 3 6 % of total project costs. 2.11.3 Contribution of effective Planning Figure 2.10 Contributors of effective Planning (Lock, 2007). Effective Planning and scheduling influences the results of a project as is promotes well-organised working. Personnel who are not trying continually to overcome crises caused by bad planning can dedicate more time to achieving high quality standards. A well-planned project stands more chance of being completed on time and on budget. 3.0 Methodology Based on the findings in Chapter Two, a questionnaire was compiled aimed towards Construction Planners, Project Managers and other Construction Professionals. The questionnaire was developed in order to reach a significant conclusion on what is happening in the industry today, confirming what challenges are faced on a day to day basis and what can be done for improvement. The author contacted various professionals in the industry whom were contacted via Chartered Institute of Building website in order to get a mixed response. A letter was sent to each individual asking if they could spare time to answer 20 questions which were related to the research. The letter can be found in appendix. In addition, an online link to the questionnaire was sent to over 40 professionals in the industry, from which over 23 people took the time to fill it in. All results can be found in Chapter 4. 3.1 Introduction The aim of this study is to analyse current planning techniques used within the construction industry and determine what influence the construction programme has in terms of project success. In order to achieve this aim, sufficient research has to be carried out. Research design is an action plan for getting from here to there, where here may be defined as the initial set of questions to be answered, and there is some set of conclusion (answers) about these questions. (Naoum 2007.) Between here and there may be a found number of major steps, including the collection of analysis of relevant data. (Yin 1994.) Developing a successful strategy was an important step towards the collection of key research information. 3.2 Research Strategy Research is the systematic and rigorous process of enquiry which aims to describe phenomena and to develop and test explanatory concepts and theories. Ultimately it aims to contribute to a scientific body of knowledge. (Bowling 2009.) There are two types of research strategies, namely, quantitative research and qualitative research.

Antidepressants and Peritoneal Dyalisis Essay examples -- Health, Trea

Antidepressants and PD Medically based treatments are commonly used in treating depression in PD patients. It is suggested that when choosing the correct antidepressant medication, the major symptom should be of focus. For example, if an anxious patient presents with sleep difficulties, a sedative antidepressant should be prescribed. However, it is noted that with the progression of PD, antidepressant should be monitored as some have negative effects with the course of PD (ex. psychomotor retardation in the case of the sedative antidepressant) (Reichmann et al., 2009). Tricyclic antidepressants are commonly used with patients presenting exclusively with major depression, but little research has been done with PD patients and should be used with caution (Reichmann et al., 2009). A Cochrane review conducted in 2003 found only three randomized control trials of 106 depressed patients diagnosed with PD and the researchers concluded that there was limited data to support the effectiveness of antidepress ants (Ghazi-Noori, Chung, Deane, Rickards & Clarke, 2003). Further research is warranted on the effects of medications used to treat anti-parkinsonism symptoms in tandem with drugs used to treat depression. The most common antidepressant used with PD is selective serontonic re-uptake inhibitors (SSRI), and interestingly, very little research has been conducted on its use and long term treatment (Reichmann et al., 2009). Treatment of depression for PD patients There is a lack of research literature on psychotherapy treatment of depression with PD patients (Veazey, Cook, Stanley, Lai & Kunik, 2009); this may be due to feasibility of long term research with this population as well as sample being unable to come to treatment... ...omplex as that found within the literature on depression and anxiety in PD. Research has linked cortical Lewy bodies and has shown cholinergic deficiency linked to cognitive impairments (Kandiah et al., 2009). Early diagnosis of dementia in a PD patient is important as effect treatments are available (Dujardin, Dubois, Tison, Durif, Bourdeix, Pere et al., 2010). Successful treatment using cholinesterase inhibitors rivastigmine and less successful with dopamine therapy have been found (Davie, 2008; Leroi, Collins & Marsh, 2006). Dementia with Lewy bodies differs from PD with dementia in that the latter has greater cell loss found in the substantia nigra and the former has greater cortical beta-amyloid deposition. Dementia with Lewy body patients is less responsive to dopamine treatment and it can intensify cognitive confusion and hallucinations (Davie, 2008).

Compare the two poems, Presents from my aunts in Pakistan and Essay exa

Compare the two poems, Presents from my aunts in Pakistan and Search for my tongue. Both poems shows people thinking about their roots and how each poem conveys their thoughts and feelings. In this essay I will be evaluating two poems from different cultures and traditions. Both poems 'Search for my tongue' and 'presents from my aunts in Pakistan' are about true identity and searching for your roots. 'Presents from my aunts in Pakistan' is mainly about a girl who is of mixed race and how she describes the gifts of clothes and jewellery sent to her in England by her Pakistani relatives. There is no rhyme scheme and the poem is written in free verse. Free verse simply means that the phrases are arranged loosely across the page. It is divided into stanzas of varying length. The girl contrasts the beautiful clothes and jewellery of India with English clothing. She describes how it feels like wearing the 'salwar kameez' and how she longed for denim and corduroy. She's drawn to the loveliness of the gifts but feels awkward wearing them because she is more comfortable in English clothes. The poem is full of associated, sometimes contrasting images. An example of a contrasting image is ' of no fixed nationality staring through fretwork in the Shalimar gardens.' Fretwork is basically decorative carving and the Shalimar gardens is an ornamental ark in Lahore, her hometown. The girl describes how life in England differs from life in Pakistan. She talks about the salwar kameez as 'alien' but wanting cardigans from Marks and Spencer's. The way the women live is somewhat different from that of England. For example her aunts were in shaded rooms, screened from male visitors whereas the women in England go o... ... left with. The speaker imagines herself there in Lahore - somewhere she has been only in her thoughts. However she is of no fixed nationality. This sounds a slightly threatening phrase. After thoroughly reading the poems, I have arrived at two main conclusions. Firstly it is important to know where one comes from, which is perhaps what the girl in the poem was lacking as a child and it is also important to know what has gone into one's making, even quite far back, I think it gives you a sense perhaps of richness. Secondly it is sometimes very difficult knowing two languages but having to neglect the one that belongs to you. One's mother tongue is an important link to your family and your childhood. Last but not least I agree deeply with the statement and I quote ' that's the deepest layer of my identity' which was said by Sujati Bhatt, the writer.
