work of gross gross revenue packaging on thirst buy grease champions palmsing demeanourPurpose The purpose of this dissertation is to get a line let on the influence of gross sales packaging on zest purchase acquire deportment. This seek is think on the securities industry seller Tesco.Design/Methodology/Approach The down beas c everyplaceed in this dissertation argon consumer buying behaviour, sales promotions and proclivity buying behaviour. Two hypotheses be positive for this inquiry and they are interrelated. trine objectives are developed and they are used to prove these hypotheses. The secondary entropy is perk uped first to k instantly what is said about this phenomenon. Primary info is collected in the form of qualitative and quantitative data. Two miniskirt focus group interviews are conducted for qualitative data. Surveys are used to collect the quantitative data. The population of the survey consisted of 78 samples from the consumers of T esco, Parnell passage. Information like demographics and shop frequency are collected to know about the details of the consumers. The data collection besides verifies sales promotional activities, passion buying behaviour and the relation among them. Data is analysed using an online survey tool called SurveymonkeyFindings- From this read, it has been mute that sales promotions have a major influence on the caprice purchasing behaviour of consumers. It has also been verified that price promotion is the to the highest degree influencing divisor of sales promotion, which drives consumers towards caprice purchase. Conclusions and recommendations at the end of this interrogation ordain be useful for students who hear consumer buying behaviour and for retailers to implement a strategy for sales promotion.Originality/Value Previous researches that has been carried out about impulse purchase has been influence of culture, mood etc. The function of this research is to find the i nfluence of sales promotion on impulse purchase, which is important positionicularly during the reliable economic recession.IntroductionThis class of the dissertation outlines the research proceeds the tec chose to carry as part of his Masters in assembly line Administration (International) in Dublin Business give lessons. This ingredient is divided into the followers parts.Background of the researchSuit skill of the detective and interest in paper interrogation Objectives and HypothesesApproach to the dissertationRecipients of the researchOrganisation of the research arena and limitations of the landing fieldBackground of the researchOnes own personal shopping experiences bank that occasionally we go into a store with no planned purchases in mind. Usually, however we go into a store planning to buy whiz or more specific items. Sometimes we know that those planned items are offered at a sale price, sometimes they are at fix price, and sometimes a mixture of both. We usually have an idea how much(prenominal) it impart cost and how numerous of them we plan to buy. However, once we are in the store, we sometimes buy all we planned to buy sometimes we buy more than we planned to buy. This would have happened because of something that perk upd us inside the store. It could be because of various reasons like sales promotions or store atmospherics or uniqueness of the product. This study is based on the influence of sales promotions on unplanned purchases like this called impulse purchase.Consumers buying behaviour is based on the chooses of the consumer. This goes down to the basic level of consumer needs developed by Maslow(1971). He suggested a hierarchy of needs from the nearly basic to the most civilised one. Physiological needs, safety needs, belongingness needs, esteem needs and self-actualisation needs. To satisfy the needs, consumer buys things and this study is on the consumer buying behaviour. The consumer buying behaviour goes thr ough a basketball team sequential steps that is explained in the belles-lettres review of this article.Practically, when a consumer feels the need for buying things, he/she goes for shopping. There are some(prenominal) types of shops available, but the retail shop is where consumers can buy the things that they need for daily life. The concept of retail shops are now changing with the evolution of queen-sized supermarkets. Retail shops are now becoming one-stop-shops called super markets, offering vast number of product categories and services ranging from fruits and vegetables, off-licence, bakery, butcher facilities and even pharmaceuticals. It is a common fact that the large grocery stores and super markets have an unfair advantage everyplace subtile players, by using a low cost selling, which the small whatchamacallum stores struggle to match. The Irish grocery retail market has evolved with many changes over the last few years. Tesco is one of the main players that exist in Irish grocery retail market.Organisations have started changing the methods of their grocery chore over the last decade. There are innovations coming in the market insouciant to attract new consumers and to retain them for a long period. Sales promotion is a quick way to strengthen the sales of an organisation. According to Kotler(2003), sales promotion is a key ingredient in trade melt which consists of diverse collection of incentive tools, mostly short term, designed to stimulate quicker or greater purchase of a particular products or services by consumers or trade. It is one of the effective methods in creating savings to the regular grocery shoppers. For retailers, the sales promotion is an excellent opportunity to tug their products in bulk thitherby increase profit margins and consumer loyalty. There are various sales promotion tools used by the retailers, price promotion being one of them. Price promotions help the consumers to buy their goods for a trim down price . There are various types of promotions which are described in the literature.A phenomenon called impulse purchase is considered as different form of consumer buying action. notion purchasing is a phenomenon by which a consumer experiences a sudden and often persistent urge to buy something immediately (Rook, 1987). It is an enigma in the marketing world, which accounts for substantial volume of goods sold every year. It is said that 80 percentage of all purchases in some particular goods categories is made through impulse purchase. Virvialite(2009) based on Kacen and Lee(2002).This is a widely used by the retailers as they attract the consumers to buy things impulsively. At the present market conditions, when market opposition is high and all types of companies apply promotion in their activities, stimulation of impulse purchasing in the market of consumer goods may become a self-colored competitive advantage. We go through this phenomenon in our daily life, knowingly or unkno wingly. It is the feeling that one cannot resist at that moment, which are affected many cyphers. An example of this would be when we see an advertisement in the store where it says one-half Price sale, Was 3.99, Now 1.99.The aim of this study is to study the influence of sales promotion on impulse purchase. This research determines if the consumers go for an impulse purchase, if there are sales promotions. There is also a second part to this research which determines if the price promotion is the most important factor in sales promotion that leads the consumer to impulse purchase. This study is an important one considering the current economic climate. In this recessionary period, consumers who are doing grocery shopping in truth care for the price factor and look for goods that are value for money. This study establishes the relation between sales promotion and impulse purchase.2. Suitability of the researcher and the interest in the subjectThe researcher is an engineering gradua te in Information Technology. The researcher has four years of work experience in I.T and business fields. Researcher has a family business back India, which deals with retail and wholesale trading of steel products. The researcher was taking care of business for one year before coming to Ireland and has an idea of what is happening in the unfeigned business world. The ultimate career goal is to take over the family business and expand it with more concentration on retail sector. This study on consumer buying behaviour will certainly help the researcher in achieving this goal.The researcher is currently working in the retail sector and has sight many consumers going for impulse purchase because of the sales promotions. The researcher himself has fall into the trap of impulse purchase when doing the grocery shopping on many occasions. This has specifically happened after the researcher came to Ireland where there are more sales promotions than seen elsewhere. This curiosity of the researcher encouraged to do a research on the influence of sales promotion on impulse purchase.Organisation elect for the researchThis research is conducted in Tesco, one of the biggest grocery retailers in Ireland. Tesco was founded by Jack Cohenand in 1919 and developed its first super market in 1956. They have come a long way through and now is the fourth largest retailer in the world, metrical by revenues and second largest measured by profits. Tesco has its base at The United Kingdom and is spread crossways 14 countries all over the world. The company started its operations in Ireland as Tesco Ireland in 1997. The theme Every Little Helps is very popular in Ireland. Tesco has almost all the services that is needed in our daily life, including groceries, bakery, clothing, and energetic network. The researcher chose Tesco for the research because of he considers it as the best place where the study of sales promotion and impulse purchasing can be do in the context of a groce ry-shopping environment. The research takes place in Tesco, Parnell Street in Dublin, Ireland.3. Research TopicInfluence of sales promotion on impulse purchasing behaviour in the context of a grocery store.The aim of this research is to find out the influence of sales promotional activities on impulse buying behaviour in the context of a grocery retail store. With this purpose, the research will be conducted in Tesco, Parnell Street, Dublin, Ireland.This research focuses on answering the following questions1. Do sales promotional activities in store have a major influence on consumers impulse buying behaviour?2. Is price promotion the major factor in sales promotion, which drives the consumers towards impulse purchase?ObjectivesIn order to answer from each one of these questions, the researcher came out with the following objectives.To identify the sales promotional activities in the storeTo find out if consumers actually go for an impulse purchase and the most influencing factor t hat affects itTo determine if price promotion is the most influencing factor of sales promotion and if consumer purchase low priced items during impulse buyingTo rationalize this research, and to obtain the answer for the research questions, certain assumptions were made initially. Two hypotheses were developed which needs to be proved or disapproved.HypothesisH1 Sales promotional activities in the store have a major influence on customers impulse buying behaviourH2 Price promotion is the most influencing factor of sales promotion, which drives consumers towards impulse purchase.Approach to the DissertationThe objectives derived will be obtained corpseatically in the research. Firstly, the secondary research is conducted using relevant sources to understand the research problem area in depth. Various sources like journals, textbooks, magazines and websites will be used in accordance with academic regulations. Primary research is carried out adjoining with the help of self-adminis tered questionnaires and focus group interviews. The quantitative data obtained through questionnaires are then analysed with the help of appropriate statistical tool and the government issue will be drawn. The hypotheses will then be tested with the results obtained and will proved or disapproved. Conclusions will be made and recommendations will be proposed based on the results.Recipients of the researchThere are five recipients of the research that is conducted as part of Masters in Business Administration (International) in Dublin Business School.

Agency Theory And Stakeholder Theory Commerce Essay

room Theory And S deliverholder Theory Commerce actThe reading of incarnate g overnance is a global issue, the issue of bodily brass has come to prominence in various fields contains refers intimacy of finance, stintings, accounting, law, oversight, organizational behaviour and so on. The term integrated governance and its r appearine usage in financial fields lose attracted much and more(prenominal)(prenominal) than than public attention in the last thirty years. There ar sorts of theories adopt in the bodily governance, while I will concentrate on two main streams of them one is situation system which is establish on the inte fill-ins of sh beholders the former(a) is s beat backholder hypothesis which is based on the lettuce of all(prenominal) told the stakeholders. The main aims of this musical composition ar introduce and explore the dominance surmisal and the stakeholder opening, comp ar and contrast these two theories.Apart from the introduction, the structure of this paper is as fol first bases the theoretical re judgment of twain potency hypothesis and stakeholder supposition is include in the next part then, I will describe the persona of the function system as well as how impairment is the say-so surmise similarly, the fourth parts consist of two aspect of the stakeholder surmise the contributions and nigh criticisms the final section is the conclusion.Theoretical re thought spot systemIn the early literature, classical economics considered that majority of quite a teensys were non precisely owned but in addition workled by the shareholders who have funding proprietors. With venerate to stand stratum of separation of ownership and fancy, it was rootly pointed out by smith in 1838. In the ulterior work of Berle and Means (1932), they hold the view that with countries industrialization and markets revealment, the ownership and control of corporations has been separated. The purpose of this action is to give an in-chief(postnominal) explanation for integrated behaviour and the hassles confronting owners (fragmented and dispersed shareholders) who attempt to exert their rights over the managers who have gained control in the modern cooperation.According to Arrow (1971), the origins of agency speculation brush aside be traced back to the 1960s and early 1970s, more and more economists detected and pay attention to the seek of infection among individuals or groups. He mentioned that in the case of different argument toward happen insisted by the cooperating parties, the luck sharing problem occurred. 6 years later, Jensen together with Meckling pointed out Agency opening in their bind in addition, they defined an agency kindred as a contract under which one or more persons (the leashs) engage a nonher person (the component) to perform near service on their behalf which involves delegating nigh decision making authority to the agentive role. For example, it is widely trustworthy that the agency kind is among the owners (as the principal) and the managers (as agents).The aim of agency theory is to set up necessary monitor to reduce the so called agency problems arise in agency relationship between the principal and the agent. One problem is that whether the behalf of agent is applicable or non can not be testified by the principals. The expect or remainders of the principal and agent conflict brings to the first agency problem more over, when it is difficult or expensive for the principal to joc identify what the agent is doing in details and exactly, agency problem rises either. The other problem is the risk sharing between the principal and the agent. Due to the different risk preferences, there is distance between the action of the principal and the agent. An overview of agency theory is given(p) in Table 1 (Eisenhardt, K. M 1989).Table 1 Agency Theory OverviewKey ideaPrincipal agent relationships should confer efficient organi zation of education and risk bearing costs social unit of analysisContract between principal and agentHuman confidenceHuman as fitption Bounded rationalityRisk aversion organizational assumptionPartial goal conflict among participants assumptions Efficiency as the effectivity criterion discipline asymmetry between principal and agent Information assumptionInformation as a purchasable commodityAgency (moral hazard and wayward selection)Contracting problemRisk sharing hassle domainRelationships in which the principal and domain agent have partially differing goals and risk preferences (e.g., compensation, regulation, leadership, impression management, whistle blowing, vertical integration, transfer pricing)Stakeholder theory of the firmsDonna mailing Charron (2007) reported that the stakeholder theory has gone by means of three gives until now. The first stage of stakeholder theory is from the 1960s through and through early 1980s, the stakeholder theory agenda was declare on e egod by the corporate revisionists. During this period, a new idea social institution was advocated to switch over the tenorholder ownership in the firm. In the early 1970s, stakeholder theory was accept by the business ethics professors. Between the late 1980s and 2000, the stakeholder theory is ongoing the endorse stage. Corporate managers turn to interest in the stakeholder theory until they know that stockholders are just one aspect of stakeholders among many. It is operative for them to check themselves against stockholder rights activities. In the middle of 1990s until 2000, corporate revisionists look previous to build the claims of stakeholders. All the participants and assistants who share the risk and create expediencys for the firms are stakeholders. They should obtain a balance share of the riches created by the control stick efforts (Clarkson 2002 1)). According to Donna Card Charron (2007), it is imperative for managers observe the following principles (1).M onitor and respond to concerns and interests of all legitimate stakeholders. (2)Communicate with stakeholders about their concerns, contributions, and risks. (3).Act with sensitivity to each stakeholder group. (4)Attempt to achieve a beautiful distribution of benefits and burdens. (5)Insure that risks are minimized and harms are compensated. (6)Never jeopardize inalienable pitying rights or deceive concerning risks. (7). Deal with the conflicts of its self interest and the interest of stakeholders through public institutions, public reports, incentive systems, and third party review. The stakeholder theory was widely acceptable by the end of this stage. In the third stage of stakeholder theory currently, Value Based Management pointed out the effects of stakeholders toward to the firms can not be ignore and even most-valuable, there is a positive relationship between the wealth of stakeholders and that of stockholders.Different from agency theory which focuses exclusively on int erests of shareholders, the Stakeholder theory concentrates on the interests of all the parties in the corporation. Stakeholder theory is considered as a theory of organizational management and ethics. Under this theory, what the managers should do is not nevertheless to maximize shareholder value, but also benefit the profits of the stakeholder group.Groups or individuals in the corporation, whose interests and benefits have a close relationship (gains or loss) with the corporation action, are called stakeholders. Sometimes, the concept of stakeholders is a generalization of notion of stockholders who can propose some special claim on the firm (R.Edward). Stockholders are given the right to demand certain actions by management similarly, stakeholders can also make claims.The assumption of stakeholder theory is the values are imperative and tactual a part of doing business. R.Edwatd et al. (2004) propose that stakeholder theory is managerial, and it reflects and directs how manag ers operate rather than legitimately addressing management theories and economists. Two key questions of the stakeholder theory are mentioned in Freemans article (1994). The first question is the purpose of the organization. This is very helpful and useful for managers to deliver the share awareness of the value they create and what brings its major stakeholder together. In addition, this release forward the firms itself expect it to create sound execution by considering both its aims and marketplace financial metrics. The second question asked in the stakeholder theory is what certificate of indebtedness management has to stakeholders. These encourage managers to know how they indigence to do business. Particularly, they are face for an appropriate kind of relationship with stakeholders to achieve their own interests. The core of stakeholder theory, economic value is that large chassiss of people come and work together to advance their situation, is accordance with the fun damental modern economic realities. In fix to impulse more and more workers to do their best for the firms, it is necessary and all central(p) for managers to develop relationships and create communication with stakeholders. (See R.Edward Freeman, Andrew C. Wicks, Bidhan Parmar 2004) It is widely accepted that shareholder is significant party in the firm and interests are a critical characteristic. In terms of profits, it is not the driver in the process of value cosmea while the results. contribution of the Agency theoryPerrow (1986) noted that the key point of the agency theory is focused on the significance of motivation and self interest. Under the agency theory, any ideas and activities of the organizations are based on self interests furthermore, a common problem structure across the research topics is important either. There are two contributions to organizational thinking created by the agency theory in Eisenhardt, K. Ms work paper (1989).First of all, breeding is consi dered as a good, in another word, information can be sold by people if it is necessary. It can be divided into white-tie information system and informal information system. The former includes budgeting, MBO, and get alongs of directors while the later one consists of managerial supervision that just in organizational research. If the principals want to know what the agents are doing and whether their action is appreciate or not, invest the information system is a good approach. An explanation of this is executive compensation (Kathleeen M. Elsenhardt 1989). A great many authors showed that they are surprised at the insufficient of performance found on executive compensations. On the contrary, since the compensation is affected by different kind of elements such as information system in the agency theory, the above argument is easy to accept.In addition, the risk import of agency theory is another contribution. There are various ambiguous future such as prosperity, bankruptcy and some secondary event that corporation may meet. Whether the future of firms is bad or sound depends on the performance of organizational participates. The outcome of firms, to large extent, is affected by the environmental factors that cover government regulation, new similar competitors, science and technology entry and so on. Agency theory encourages the ramifications of outcome uncertainly to indication for producing risk. For instance, some behaviour of principals in the companies such as make or bargain for decision is not influenced by the uncertainty technology and demand (Walker and weber 1984). Although they do not know that the reason is transaction cost modelling their conclusion covers the idea of agency if the managers of the firms are risk inert. Walker and weber concluded such a conclusion that outcome uncertainty is not associated with risk neutral principal. On the other hand, the outcome uncertainty is passing sensitive to risk principals in new venture. If the firm is new and not big enough, the limitation of capital and resources for predicting the uncertainty will lead to the oftenness of the failure. The managers on such firms are risk averse principals. From the agency theory perspective, the relationship between managers and outcome uncertainty is extremely close. For example, in dress to maintain and develop the firm, managers are more likely to adopt buy decision to transfer risk. On balance, agency theory predicts that risk neutral managers are likely to choose make option (behaviour based contract), whereas risk averse executives are likely to choose buy (outcome based contract).How wrong is the agency theory?The adoption of the agency theory for corporate governance give out widely accepts all over the world, especially in the UK and the US. The agency theory indeed brings some merits for the corporations. However, more and more faults are showed by the recent literature research and firm practice like Enron, Xerox, and WorldCom. This paper will focus on the Enron to explain how wrong the agency theory is.Thousands of employees losing their life savings tied up in the energy caller-outs stock due to the collapse of Enron which is considered as the largest bankruptcy in US level (Thomas Clarke 2004). The following introduction about the Enron is based on the lecture notes of go after Wearing (2008). Generally speaking, Enron is an intelligent gambling that covers many aspects firstly, allow noble risk accounting secondly, allowing 50% of assets to be shifted into off balance sheet of paper entities thirdly, waiving the ethics code to allow self dealing transactions fourthly, ignoring directors conflicts of interests Finally, impuissance to monitor executive compensation. The foundation of the Enron business is risk management. It expects to get frontward to traditional, vertically integrate kind of institution by using risk management. Enron adopt its own methods to protect the Enron stock, it s funds will be rarefied when Enrons share price fell. Bankruptcy is the destination of Enron once credit agencies decreased Enrons rating. Most non executive directors are paid as consultant from the directors fees consequently, they can not be characterized independently. At the same time, directors received various types of gifts from Enron. The dirty money for Andrew Fastow (CEO) remains a secret, and another CEO (Kenneth Lay) get much overwhelm money from the company. In the case of decreasing of the companys stock in 2001, get on members and senior employees obtain profit by cashing in share options, meanwhile, the rest of employees do not loss anything as they let their pension plans out of Enron stock.All in all, the shortcomings of the agency theory become obvious. In the first place, due to the asymmetric information system, the deficiency of agency theory that covers several(prenominal) aspects is become obvious. The first one is called moral hazard agency conflicts that are the root reason for the Enron failure. Moral hazard agency conflicts were mentioned by Jensen and Meckling in 1976. Moral hazard arises when the agents action, or the outcome of that action, is barely imperfectly plain to the principal. A manager, for example, may exercise a low level of effort, bollocks corporate resources, or take inappropriate risks (Joseph Heath et al. 2004). Jenson (1986) hold the view that fresh cash flow will face much more difficulties from moral hazard problem in big and developed companies. In addition, moral hazard problem is relevant with the inefficiency of managerial effort. The motivation and rapture of managers will be dropped off for small equity stakes they own. Thereby, company value will be affected or even harmed. The second one is named adverse selection. Adverse selection can arise when the agent has some private information, prior to entering into relations with the principal. Individuals with poor skills or aptitude will present themselves as having superior ones, people with low motivation will apply for the positions that involve the least supervision, and so frontwards (Joseph Heath et al. 2004). In the second place, shareholders, the owner of the company, are able to jazz the companys residual claims. They shoulder the operating and capital risk rather than satisfying risk. Other stakeholders such as creditors, managers, employees who shares risks should be given the similar rights.Contribution of stakeholder theoryAccording to the stakeholder theory, the objective of corporate existence is nor the shareholders only. The close nexus in the corporate social responsibility (CSR) that is the main stream of the corporate tendency is a apparent contribution of the stakeholder theory. A large build of literature and research find out that companies concentrate on CSR which is considered as origin of competition advantages is more likely to accept and get benefits. It is, to some extent, benefits the cor poration as a whole, in the long runs at least.ever-changing the objectives of corporate governance from the maximize the interests of shareholders to maximize the value of the company. Stakeholder theory breaks through the traditional framework. The stake of firms owned by a large number of dispersed shareholders in modern enterprise. The maximisation of the interests of shareholders does not mean the maximization of corporate value, or even scathe the interests of other stakeholders, such as the hostile takeover. Stakeholder theory suggests that the other individuals and parties should also be considered stakeholders, such as creditors, employees, suppliers, customers, government and community, corporate governance should be the stakeholders of the coordination mechanisms of conflict of interest, balance and co ordinate conflict of interest to all stakeholders to maximize the benefits (Liu Dan 2003).The motive of corporate is redistributed in the process of game among stakeholde rs. Modern companies are characterized by separation between ownership and control thereby a principal agent relationship is formed between the principal and the agent. Unfortunately, the interests of these two parties are not al steerings consistent. The managers tend to abuse their special power and damage the interests of shareholders by the reason of their insider status. The agency cost problem occurs when an efficient monitoring system is needed. The main purpose of corporate governance is not only monitoring managers in effect(p)ly but also minimizing agency costs. The traditional focussing to adjust the dimension of the structure of the board of directors are enhancing the independence of the board of directors improving the control of shareholders in order to strengthen their position create institutional investors to effective the rights of shareholders (Liu Dan 2003). But these ideas only deal with problems partly. It is difficult to neuter the level of corporate gove rnance fundamentally. Stakeholder theory suggests that the key point of corporate governance is as follows it is unavailable to deliver much more rights and control to shareholders. On the contrary, managers should be separated from shareholders who usually give pressure and tolerate enough rights and interests to other stakeholders such as employees, creditors and so on. For instance, one important programme is allowing the key stakeholders become the companys board of directors and supervisors by increasing the ownership and control of the company (Liu Dan 2003).The highlight of tender-hearted capital is advocated in stakeholder theory. traditional theory holds that the owner of firms is the investors who provide capital for firm accordingly, the ultimate goal of company is to safeguard the interests of investors. Here the word capital is limited to animal(prenominal) capital, but not human capital. This argument is acceptable and suitable in the early era of large scale indust rial machinery, while not appropriate and outdate in current era of knowledge economy. The existence and development of the organization is increasingly affected not only by the management degree of managers but also the advanced technology of workers. Technology and other human capital contribution to the enterprise are far more than physical capital (Liu Dan2003).Criticism of the stakeholder theoryOn the whole, stakeholder theory is incongruous with good corporate governance for it is with business (see Elaine Sternberg 1997). Accountability is one of the most important concepts in corporate governance. It consists of directors to shareholders, firm workers and other corporate agents to the internalisation as well. The notion that the owner of firms is responsible for their corporation is disapproved in stakeholder theory. On the other hand, what the stakeholder theory calls for is all the stakeholders are responsible for corporations. Such key principle is not realistic checked and work out wholly. Everyone take charge of company means no one will take charge of company. Various accountability make scent out if all the stakeholders have a clear similar goal, otherwise it does not make sense at all. However, the stakeholder theory prefer to the later.More over, there is not an effective standard to judge and evaluate corporate agents given by stakeholder theory (Elaine Sternberg 1997). Duo to the unclear balancing stakeholder profits, it is not a good way evaluate objective performance of firms. It is discretional for managers to seek their own interests which are always selfish by using this method. Consequently, stakeholder theory has comprehensive control of haughty and selfish managers as well as lavishness wages, perk and premises. At the same time, the phenomenal of empire building acquisitions that make little business sense exists widespread in the stakeholder theory. Even though the original purpose and expectation of the stakeholder theory is h opeful, it is difficult to carry on and heighten corporate performance as well as corporate governance. impertinent the traditional theory which described that objective of firms is maximizing economic profits objective in the stakeholder theory covers social, political as well as economic field. The efficiency of the business operation will be change in such situation. This leads to a dilemma for the company firstly, pursuit of profit maximizing hence enhance the social costs and increase the loss of social welfare. Secondly, negative externalities of business activities will be reduced by using various types of control means, but they worse the inefficiency of economy.ConclusionTo sum up, two popular theories used by corporate governance, agency theory and stakeholder theory are introduced and compared in this paper. The original purpose and expectation of these theories is to develop and enhance the level to corporate governance. The key diversity towards corporate interests be tween these two theories is for agency theory, the interests of shareholders mean the corporate profits with respect to the stakeholder theory, corporate interests should cover the profits of all the stakeholders.Different from traditional theories, agency theory pays unprecedented attention on information system, outcomes uncertainty and risk. These performance are beneficial for corporate alleviate or even avoid some conflicts and problems between principals and agents. However, after the case of Enron which is a characteristic failure, people become aware of shortcomings of agency theory. Due to the asymmetric information, moral hazard and adverse selection bring difficulties to governance. Even though, stakeholder theory does not have a clear notion about the quantity and quality of stakeholders, and it is, to some extent, chimerical to carry on the contribution of stakeholder theory can not be ignored. Changing the objectives of corporate governance from the maximize the inter ests of shareholders to maximize the value of the company. The power of corporate is redistributed in the process of game among stakeholders. The highlight of human capital is advocated in stakeholder theory. To conclude, I pose that the stakeholder theory is much more appropriate for the modern companies for the long run.

The Lamentation over the Dead Christ

The Lamentation everywhere the stone-dead ChristClassicism in The Lamentation over the suddenly Christ The renascence Era was an epoch of craftistic resurgence in the story of Europe. This period was marked by developments in Italian Renaissance word-paintings with the regeneration of classical forms, motifs and subjects. In edict to discern the Classicism that prospered during this age, conceivably without need, from the unstained architecture of the ancient Romans. The exploration for cerebral legitimacy through and through art set apart the period. During this period, contemporary Classicism was described as the comme il faut technique. Methodically, this set in motion a assail against baroqueness art, which, with its high etherealing of embellishment and delusion, was considered to be distinctly fictitious. Andrea Mantegna (1431-1506), in particular, sculptured his prevail entitled The Lamentation over the shortly Christ (c.1480) in bedrock of Classicism.Mantegna u sed mainly foreshortening, a location used for force objects from a definitive viewpoint and chiaroscuro, the contrast among light and fantasms bet this painting to vitality with essentials of Classicism. In this period, Classicism to a faultk on more visibly structural insinuations of the use of locating, chiefly by the use of Foreshortening. Foreshortening occurs when an object appears mingy when seen from a particular viewpoint, and the effect of scene causes distortion.Foreshortening is a predominantly structural creative mechanism, used to go forth the sense of three-dimensional energy and succumb emotion in a picture. To sensationalize the supine Christ in perception, Mantegna paints his light source higher up the horizon commercial enterprise, to create illusion that the witness will appear to be looking at an angle. The more wonky the vanishing point, the more slanted the icon will be, as seen in the painting. Because the system of Christ is supine and sym metrical, the vanishing point is diametrically in the core of the perspective line. Because the spectators plane is parallel to Christs head at this point, the base perspective line appears to be horizontal. This imaginary line gives the fundamental, foreshortening perspective. The farther away the image is from the mantrap, the nigh the illusion is to existence perpendicular to the portrait plane, as seen in the Dead Christ. The position of the mourners (The Virgin Mary and St. John) are on the horizon line, to the left cogitation the desertion point (Christs Head), as an new(prenominal) foremost model to air this position of foreshortening. The expanse from this point to the center of the perspective line denotes the blank in spite of appearance the painting for the viewer. If the point is isolated from the vanishing point, the mourners will appear condensed, and distant. If it is too close, they will emerge leng soed, as if it is too close to the observer. Essentially dist orting the beam of light traveling from its origin to the onlookers judgment and ruining the illusion in spite of appearance the painting. This element is key to understanding Mantegnas brilliance of perspective in this fresco. In the case of the holes in Christs hands and feet the perspective of the light source that illuminates (at an angle) the commonwealth of the holes also represents the use of foreshortening on the picture plane. When the light source hits the demesne of the holes, it hits at the appropriate angle on the picture plane. In invest for the resulting image to appear identical to the intended scene, the shopping centerwitness of the perspective must scrutinize the image from the exact vantage point used in the geometric calculations comparative to Christ. This proper use of foreshortening abandons visual imperfections that what would appear to be alterations in the painting when analyzed from a discrete point. These conspicuous distortions in foreshortening a re more evident when viewing Christs thorax as the perspective estimated from the surroundings, to the spectator be falls more finely tuned and comparative to the portrait base.In application, unless the viewer desires a radical perspective, like viewing the body of Christ from the base, the perspective on the whole, is in all probability accurate. It has been recommended that a painting in standpoint still seems to be in perspective at other spots because the individual still distinguishes it as a painting, because of the quality in its profundity of field indications due to the use of foreshortening. For a emblematic perspective, conversely, the field of view in the Dead Christ is tapered to the point, that the distortions are miserable and the fresco can be viewed from a site other than the patent designed vantage point without seeming distorted, which in turn, buttress Mantegnas polish to paint the feet of Christ less significant than the customary individuals. While speechm aking at a summit on Greek mathematics and philosophy, Plato (429-347 B.C.E.) was quoted in repute to art run short, as stating,Thus (through perspective) every sort of confusion is revealed within us and this is that weakness of the human mind on which the art of create and of deceiving by light and shadow and other ingenious devices imposes, having an effect upon us like magic And the humanities of measuring and numbering and weighing come to the rescue of the human understanding (Plato qtd. in Kahn)The applied use of the mien chiaroscuro, is the outcome of light representation in painting, in which three- dimensional capacity is advocated by the measure of color and the systematic partition of light and shadow contours on a two dimensional plane in a model of artwork. The creation of these belongings in the West, Skiagraphia or shadow-painting to the primeval Greeks, was attributed to the noteworthy Athenian painter of the 5th century BC, Apollodoros. In the print of the Dead Christ, the light is approaching in from one encoded course exceeding Christs body, then light and silhouette will match to a set of inwrought conventions. An underscore of luminosity on Christs shroud symbolizes the summit where the brilliance is being revealed most unswervingly. This is most often attributed as a lightened white area, as seen in the shroud in Figure 1. As the viewers eye moves away from this emphasis, radiance strikes the article less candidly and consequently broad throw ups a darker assessment of hues on the shroud. This changeover continues until the onlooker reaches the point where the darkness of the bitingly drawn material meets the lighted portion of the shroud. Here, there is a more abrupt conversion to darker values since no light is salient between Christs feet. Some oblique light is offered on the underside of Christs feet as the soften side does not turn unyieldingly dark. This is the product of reflected and refracted daylight that logically bese em apparent within the painting. As the viewer looks at the intense flesh of the body of Christ, it is noticeable that it is patently lighter than the shadowed area of the mourners. flicker in the environment is illuminating the background. The throw shadows are at odds, with pick out values as well. Then, as light becomes more available, the same cast shadow lightens in increments until it reaches the shadows circumference. Craigie Aitchison (1923-2009), a Scottish painter and one of the amend known critically esteemed Royal Academians (Members Royal Academy of liberal arts have a exclusive position in being accepted as reputed artists and architects whose sole objective is to endorse the creation, pleasure and awarnessof the visual arts through exhibitions, education and debate), recalls the Dead Christ as his favorite painting, stating, I like it because it tells a Story Its a wonderful reddy colour and toppingly drawn If ever a painting was clear, its this one. Its fantast ically clear close to the story its telling theres no muddling about. It couldnt be any other way. (Aitchison). Mantegna dominates and operates this modus operandi to provide a inventive sense of pathos in the mourners and character in the Dead Christ. The Mantegna painting, with light entering from above, illustrates a faint modeling of chiaroscuro to give quantity to the body of Christ, which in turn, confirms the strong stimulus of Greek enliven Classicism in this fresco. The contrasts between light and shadows bring this painting to life with essentials of Classicism. The Renaissance Era was an epoch of artistic resurgence in the history of Europe. This period was marked by developments in Italian Renaissance paintings with the renewal of classical forms, motifs and subjects. In edict to discern the Classicism that prospered during this age, conceivably without need, from the Classical architecture of the ancient Romans. The exploration for cerebral legitimacy through art se t apart the period. During this period, contemporary Classicism was described as the proper technique. Methodically, this set in motion a blitz against Baroque art, which, with its highlighting of embellishment and delusion, was considered to be distinctly fictitious. Andrea Mantegna (1431-1506), in particular, modeled his work entitled The Lamentation over the Dead Christ (c.1480) in rudiments of Classicism.Mantegna used mainly foreshortening, a perspective used for compressing objects from a definitive viewpoint and chiaroscuro, the contrast between light and shadows bring this painting to life with essentials of Classicism. Mantegnas version of the Dead Christ, is regarded as an indispensable art put together exemplifying the use of Classicism. Thus, he deserves the acclaim for the merit of these essentials in his work of art.

A History Of Fly By Wire

A History Of take flight By WireAbstractThis research spread over provides a historical portrait of the teaching and implementation of fly-by-wire passage check dusts. The report informs to the reader what rush gos ar. It provides an overview of major innovations in feather take for arrangements. It then goes on to beg off what a fly-by-wire escapism get over system is and discusses the NASA development computing device programme that made fly-by-wire a reality. It then discusses the F-16 Fighting hunt which was the startle mass produced aircraft to utilize a fly-by-wire system. The benefits of fly-by-wire escape valve guarantee be discussed as is the expansion of fly-by-wire course check up on systems into commercial and full general aviation. Finally, a conclusion on the substance of this report is provided.1. IntroductionPurposeThis historical research report describes the development and implementation of fly-by-wire flight manoeuver systems in orde r to satisfy the formal report requirements outlined in the var. syllabus for EGR 3350, Technical Communications for Engineers and Computer Scientists.1.2 BackgroundEver since the flick of cater pitying flight was effected by Orville and Wilbur Wright in celestial latitude 1903, engineers and aeronautic innovators have sought to prove more efficient and natural rubberr methods of aircraft flight go out. The evolution of flight entertain systems from human powered mechanically clevernessful linkages to fly-by-wire calculating machine systems cook ups a marvelous display of aeronautical plan progression. Fly-by-wire flight ascendence systems pointed a great leap in aeronautical thinking and envisioning from mechanical linkage and tumid hydraulic systems to computer-aided galvanising flight ascertain systems. An obligate by Gray Creech of NASAs Dryden escape valve Research Center explains how 1 these systems created frightful benefits for the aero lieu intentnes s allowing boiler turn reduction of weight and aircraft system redundancy change magnitude asylum of flight. NASAs fly-by-wire development program was the first program to succeederfully institute an galvanic flight run into system without a mechanical backup. This programs success led to the first mass produced fly-by-wire aircraft, General Dynamics and Lockheed Martins F-16 Fighting Falcon, the space shuttles fly-by-wire flight suss out computer, and many another(prenominal) advancements in fly-by-wire flight learn that atomic number 18 now being realized in the commercial and general aviation industries.1.3 ScopeThis report impart explain to the reader what flight learn is and detail a brief history of aircraft flight figure and the innovations that preceded fly-by-wire system development. This report will then discuss NASAs fly-by-wire development program and the initial deployment of this engineering science in the F-16 Fighting Falcon. This report will explain the many benefits inherently derived from employing a fly-by-wire flight prevail system. Finally, this report will detail how this flight pull wires system evolved to be make use ofd in the commercial and general aviation industry. This report will not stretch out future trends of fly-by-wire flight check systems.2. Discussion2.1 What is outflow Control?The control of flight of an aircraft is determined by control surfaces on the aircraft body that are adjusted in coordinated movements by a flight control system that orients an aerospace vehicle around three axes of motion. These axes of motion are referred to as gawp, have, and roll. pick up 1 illustrates these axes. icon 1. Aircraft Axes of MotionDr. William Elliot gives a great abridgment on how these axes of motion are affected by control surfaces.2 1. form (vertical) axis, perpendicular to the surface of the wings. Movement about the vertical axis in flight is called yaw. In most modern aircraft, stability in yaw is affe cted by a unflinching vertical fin in the rear active control in yaw is accomplished by a movable rudder fixed seat the vertical fin.2. Longitudinal axis, bye through the fuselage from front to back. Movement about the longitudinal axis is called roll. stableness in roll is taken care of by wings fixed at a slightly upward angle (dihedral) active flight control in roll is done by flaps (ailerons) behind the outer wings.3. Lateral (horizontal) axis, passing through the wings approximately from bug to tip. Movement about the horizontal axis is called pitch. Stability in pitch is conferred by a fixed horizontal tailplane flight control in pitch is accomplished by elevators mounted behind the tailplane. In controlling these surfaces, a original utilizes various control mechanisms much(prenominal)(prenominal) as mechanical linkages, hydraulics, trim tabs, actuators, and, in the case of fly-by-wire systems, electricity and computers to create the coveted return on the flight contr ol surfaces based on the vanishs input.2.2 abbreviated History of Flight Control System ProgressionDr. Elliot continues to explain that afterwards 2 Glenn Curtisss patent of the aileron, the basics of modern flight control were firmly established, and the top was a standardized cable-operated control system. 2 In this standard arrangement, a whiz control column (or stick) was used to operate both elevators and ailerons through a series of cables and pulleys in a similar fashion, the rudder was moved by stern pedals. The physical strength of the pilot was all that was required to augment these control surfaces in flight for slow contemptible aircraft. The physical limitations of pilots began to be realized as aircraft became quicker and heavier. 2 This problem was initially solved by the knowledgeableness of small flaps (tabs) on primary control surfaces. These surfaces utilize the air flow acting on the tabs to move the main control surface they were link to. The developm ent of automatic piloting systems was also on going at this meter and 2 steady advances in autopilot engineering science led to the development of mechanical boosters to assist pilots in moving control surfaces of very large aircraft. 2 Successive aircraft produced during the late 1940s and early 1950s move to stir great advances in hydro-mechanical flight control systems. 3 During this time period hydro-mechanical control systems develop into 3000 pounds per square inch hydraulic systems as seen in figure out 2.Figure 2.

Interestingly, prior to the institution of fly-by-wire flight control systems, 2 artificial feel systems were incorporated in flight control systems to take a path the need for pilots to feel as though they were still mechanically attached to the aircraft flight control system even though hydraulic systems bust this connection between pilot and control surface. These advancements in flight control technology culminated in the desire for an electrical means of flight control system execution.2.3 What is a Fly-By-Wire (FBW) Flight Control System?2 Aerospace Recommended Practice (ARP) defines FBW as a flight control system wherein vehicle control selective information is transmittable completely by electrical means.A FBW control system is a computer system that monitors pilot control inputs, various parameters such a s airspeed, altitude and angle-of-attack, and outputs flight control surface movements with the objective of retentiveness the aircraft indoors its designated flight envelope. Literally, this computer interprets electrical signals via pilot control and detector input and outputs electrical signals to actuate the corresponding control surface in order to achieve the desired flight orientation.The flight envelope refers to the safe operating characteristics an aircraft is designed to fly at given different speeds, altitudes and other variables. The actuation of a fly-by-wire system is effectively the same for all such systems, let outly the system employs electrical signal inputs to create electrical signal outputs. However, these systems can be deployed with a varying array of design elements or control law algorithms that decide how the system will react in a given situation as well as what entity, human or computer, has superior control of the aircraft at a given time. This wor st will be elaborated on in a posterior section.2.4 NASAs Digital Fly-By-Wire (DFBW) Development ProgramOn May 25, 1972 at NASAs Dryden Flight Research Center, the first flight to successfully demonstrate a digital FBW flight control system without a mechanical backup was conducted. 1 fight for the concept at NASA Headquarters came from Neil Armstrong, himself a former research pilot at Dryden. He served in NASAs Office of Advanced Research and Technology following his historic Apollo 11 lunar landing and knew electronic control systems from his days training in and operating Apollo spacecraft. Armstrong suggested that the Dryden DFBW team adapt an Apollo program digital flight control computer. It wasnt long, however, before the DFBW program developed a digital flight control computer that significantly advanced the tell apart of the art. This was demonstrated by the fact that for the Space Shuttle, designers turned to the DFBW program for a flight computer for the Orbiters. The result was a classic case of in-house technology transfer. The original digital flight control computer development from Apollo proceeded to the DFBW program and then back again into space aboard the Shuttle. The program apply a Navy F-8C Crusader for testing which incorporated the use of computers in fashioning the flight control surface deflections that corresponded to the pilot input. 3 NASAs DFBW program, consisting of 210 flights, lasted 13 years. Figure 3 6 shows the avionics bay of the test aircraft where the computers that managed the flight control system were installed.Figure 3. F-8C Test Aircraft Avionics Bay2.5 F-16 Fighting FalconOriginally developed by General Dynamics and now produced by Lockheed Martin, the F-16 was the first mass produced aircraft to use a FBW flight control system. The F-16 has seen multiple upgrades since its service debut in the 1970s. These upgrades are typically called resists and are designated by a number. In the F-16s case, 4 the F-16 A /B example consists of blocks 1, 5, 10, 15, 15OCU, and 20 while the F-16 C/D model consists of blocks 25, 30, 32, 40, 42, 50, and 52. There also is F-16 E/F block 60 models developed for the United Arab Emirates, an F-16 MLU (Mid Life Update) block, and various other F-16 models developed for special purposes or foreign customers. These blocks signaled upgrades in areas such as avionics, engines, engine inlet area, and weapons capabilities to name a few. According to Joe Sambor, a Lockheed Martin aero field service engineer, 5 all F-16 block designations developed prior to block 40 utilized analog flight control computers while all later blocks including block 40 utilized digital flight control computers. The difference between analog and digital computers lies in the way they process information. Analog computers work in a continuous time environment where selective information can take on an infinite set of values which results in no loss of transmitted data however, its implemen tation is cumbersome requiring an extensive hardware embodiment. Moreover, this hardware configuration is difficult to upgrade. Digital systems operate in a discrete time environment where data values are finite. Loss of data is augment by high resolution and sampling rates which effectively renders data transmission loss negligible. The benefit in system implementation is in the first place software based providing smooth transitions for system upgrades and reduction in overall system cost and maintenance. The F-16 utilizes four separate flight control computer systems which work together to select the proper flight response output at any given time. This flight control configuration is considered a good deal immune to failure as long as power is apply to the aircraft.2.6 Benefits of Fly-By-Wire Flight Control SystemsOne of the great benefits FBW technology brings to the aviation industry is the ability for aerospace engineers to design an aircraft to be inherently unstable all owing for increased maneuverability. previous to FBW, aircraft had to be designed to inherently want to return to straight and direct flight. This meant that maneuverability was diminished due to the fact that, in order for the aircraft to maneuver, the aircraft had to first overcome its inherently designed stability. FBW systems are able to monitor aircraft flight in real time allowing aircraft that could never fly with simply the skill of the pilot because of the aircrafts instability the ability to take to the skies. Also, 6 aircraft weight is reduced with the removal of mechanical linkages and reduction in hydraulic system components. Enhanced safety is provided by the redundancy design of electrical circuits as well as the computers ability to respond to an adverse flight condition much faster than a pilot. The overall cost of the system is reduced as slight hardware and mechanical parts are required, fuel efficiency of the aircraft is increased, and passengers visualize gr eater comfort derived from the increased aircraft handling characteristics. Furthermore, the system can be designed to control the flight envelope keeping the pilot from making control inputs that would put the aircraft outside its safe operating capability. Also, digital FBW control systems can accept input from any aircraft sensor reducing inflexibleness constraints in system design.2.7 Expansion of Fly-By-Wire Systems in AviationCurrently, DFBW flight control systems are available in every aspect of government, military, and commercial aviation. These systems are deployed on helicopters, fighter jets, stealth bombers, and commercial airliners. Even general aviation is starting to see the benefits that DFBW technology has to offer. Mark Tatge, a writer for Forbes magazine, explains that 7 small-piston aircraft and duty jets are undergoing a radical upgrade. Digital technology developed for engagement fighters and commercial aircraft 20 years ago is finally making its way into t he cockpits of small aircraft, often at a fraction of the cost of the electronics before long installed in Boeing jumbo jets.Major airlines like Airbus and Boeing have already begun moving their fleets toward the DFBW domain. Airbus made this move with its A320 aircraft, 6 the first commercial airliner to have DFBW technology. Boeing subsequently followed suit by employing DFBW technology on its 777 and 787 aircraft models. It is interesting to note however, that Airbus and Boeing differ in the employment of their respective DFBW flight control systems and algorithm control laws. An article written by Brian Palmer summarizes the differences between the two aircraft manufacturers. Palmer explains that 8 Airbus employs a joystick that electrically connects the pilots input to the flight controls where Boeing employs the standard yoke that still uses cables to deliver pilot input commands. Airbus also utilizes control algorithms called flight envelope protection that keeps the aircraf t from flight outside its designed operating area. Boeing gives more latitude to the pilot in being able to push the envelope when appropriate. Palmer also goes on to explain how 8 it is unclear as to whether flight envelope protection makes air move around safer. Palmer cites two aircraft incidents namely, China Airlines Flight 006 and the crash of an American Airlines jet in November 2001 where flight envelope protection could have hindered the aircraft flight control recuperation or could have prevented the crash, respectively.3. Conclusion3.1 SummaryThe employment of flight control systems over the past one hundred years has seen quantum leaps in the design and theory behind how a pilot actually controls the flight of an aerospace vehicle. DFBW technology has exponentially increased the safety of flight for millions of people. This area of engineering owes its continued refinement and evolution to countless individuals and organizations who have taken on the altercate of deve loping the control systems that advance the safety and efficiency of flight. It is amazing to opine back in history on the evolution of aerospace vehicles and recount that within fifty years of human beings first successfully completing powered flight that autopilots were flying planes without human pilot commands from Canada to England. That physical power of flight controls was supplanted by hydraulic actuation which in turn was augmented with electrical circuits. That the advent of seemingly unrelated hardware such as microprocessors and logical system circuits would have such a profound place in aim an aircraft to fly. That the innovators in this field had the vision and courage to trust their knowledge and engineering skill in putting the lives of capable pilots in the hands of a computer system. The flight control systems currently deployed in aviation constitute some the most well engineered, capable and, failure resistant electrical systems ever created. However, it should be noted that such systems seem to still be in their adolescence and much discovery and improvement is left to the next coevals who endeavors to improve upon and invent the future of aerospace flight control systems.Sources Cited1 Creech, Gray.

Water Analysis to Determine River Tees Chemical Composition

weewee supply Analysis to Determine River Tees Chemical CompositionWater synopsis to determine the chemical composition indoors a ingredient of the River Tees, and the fight between fresh-cut wet en proves and Sea irrigate.IntroductionWater is unitary of the most fundamental requirements for mans constituteence on humanity it is required in so m some(prenominal)(prenominal) functions such(prenominal) as for drinking, planning agriculture and even transportation either biological, ( source) or non-biological such as cargo ships, (Hunt Wilson, 2002).Without peeing, tone as we know it would simply cease to exist Water is one of earths most renewable resources. As such, it is vital that water contented is analysed to monitor toxic and non-toxic chemicals raiseing the water systems, monitor global anthropogenic impact, react quickly to chemical contaminant through accidents or industry, and to enable safe water systems for domestic and unsophisticated use. One such example of where water analysis has been instrumental roleal is after(prenominal) the recent floods in the UK where overflow from sewers, rivers and run off from industrial sites has whollyowed chemicals to enter into water systems. Analysis of these systems allows for the damage to be assessed and necessary action to be taken, (Environment Agency, 2014).Our aim of the practical was for us to understand the different orders of water analysis. We conducted a number of tests on a number of fresh water samples and one sweater sample to determine the levels of pH, saltiness, conductivity, dissolved oxygen, treat content, ammonia and phosphate content within the water samples this enabled the analysis of whether there were differences in chemical content between the fresh water samples and ocean water.Hypothesis That there is a difference in chemical composition within water samples taken from trey sites along the river Tees and a difference between freshwater and sea water.Metho dpHWater samples from the shorthorn University section of the River Tees were analysed utilise a mixture of both a hand held ultra amount (Myron) and a probe meter. A 10ml quantity of water from all the samples taken was placed in a test tube. A pH probe meter was inserted and the pH results put down. apply the electronic hand held analyser, the samples were analysed by placing a small amount of the sample into the analysing cup attached to the device. The lid was replaced and the pH button pressed to toss off the analysis. The results were recorded as shown in turn off 1.SalinityWater salinity was measured by employ a hand held salinity meter with a salinity tramp of 0-100% (density 0.001sg). A small amount of the water sample was placed onto the deviation prism. The cover plate was closed and the instrument was held up to a light source (natural light) and the reading taken from the salinity gauge and recorded. The analysis was repeated for all the samples and the results w ere recorded as shown in shelve 2.conductivityAs per pH but using the Conductivity function on the Myron multi-meter. The analysis was repeated for all the samples and the results were recorded as shown in table 3.Dissolved O2As per pH but using the dissolved O2 function on the Myron multi-meter and the analysis was repeated for all the samples and the results were recorded as shown in table 4.Nitrate (Nitratest)Nitrates in the water samples were cut down to nitrites using a zinc based reduction agent, (Nitratest powder and Nitratest tablet). The solutions were accordingly transferred to a clean test tube where a re-agent was added, (Nitrocol tablet). The solutions were then analysed for nitrate levels using the Palintest 8000 photometer and the analysis was repeated for all the samples and the results were recorded as shown in table 5.AmmoniaWe tested the water samples using the indophenol method by the addition of chlorine and catalysts that react with ammonia to form a coloure d solution, (Indophenol complex). fig1. Reagents in the form of tablets were then added and the sample solutions analysed using the palintest 8000. The analysis was repeated for all the samples and the results were recorded as shown in table 6. channel For the Sea water sample (Sample 1), Ammonia conditioning agent was added to stay fresh the precipitation of salts.Fig 1. Water samples in Indophenol complex form foregoing to examen for Ammonia.phosphate LRWe tested for phosphates by reducing the samples by ascorbic paneling as phosphates react under acidic conditions with ammonium. Catalysts were added to ensure a rapid colour movement as well as an inhibitor to deter any influence from silica present in the solution. Reagents were then added and a boundary of 10 minutes elapsed prior to placing the samples for analysis testing using the palintest 8000. The results were recorded as shown in table 7.ResultspHThe pH determine of both the fresh water and sea water samples analyse d all fierce within close proximity to each other and within the parameters of customary surface water of pH6.5 pH instrument panel 1. pH determine from water samples taken from the Durham University firmament of the River Tees and one sample of brine.Salinity altogether one sample (Sea water) registered for salinity when tested. The Reference -Composition salinity (SR) was 30, (SCOR/IAPSO works company 127, 2008).Table 2. Salinity values from water samples taken from the Durham University theater of the River Tees and one sample of seawater.ConductivityElectrolyte conductivity recorded in the samples ranged from 8.4 S/m in the sea water sample and between 9.6-10.85 S/m in the freshwater samples. The Seawater sample was high than the design range of 5 S/m, and the fresh water samples were within radiation diagram parameters 5-55 S/m. (California State Water Resources Control Board, 2004). As shown in Table 3.Table 3. Conductivity values from water samples taken from the Durham University celestial orbit of the River Tees and one sample of seawaterDissolved oxygenSample 1, (Seawater) water bring back within the normal range for DO2 as recommended USEPA of 80% DO=83.6. (Canadian Council of Ministers of the Environment, 1999). Samples 2-4 (Freshwater), excessively fall within the guidelines of freshwater DO2 based on CCREM guidelines of 65% and 100%, DO=76.2-98.7% (Canadian Council of Ministers of the Environment, 1999), as shown in table 4.Note All samples were analysed in testing ground conditions at room temperature and as such atomic number 18 subject to the relevant physiological conditions such as pressure and temperature which should be considered, (Henrys rectitude etc).Table 4. Dissolved Oxygen values from water samples taken from the Durham University area of the River Tees and one sample of seawater.NitrateAll the samples tested were within the safe limits of nitrogen content in water, (0-10mg/l), as shown in table 5. (Seawater = 0.8 2mg/l and freshwater =0.047mg/l to1.52mg/l). (World Health Organisation, 2011).Table 5. Nitrate values from water samples taken from the Durham University area of the River Tees and one sample of seawater.PhosphatePhosphate levels found in sweater were within the normal range (1.2 mg/l and 1.6mg/l), (Paytan McLaughlin, 2007). The phosphate levels found within the freshwater samples sink the recommended limits = . Table 6. Phosphate values from water samples taken from the Durham University area of the River Tees and one sample of seawater.DiscussionThe ocean contains approximately 97% of all the Earths water. (Hunt Wilson, 2002). The ocean and fresh water although have similar properties such as the molecular structure H2O, the chemical properties can be quite different.thither are many factors that affect the chemical properties of both fresh and sea water, such as pollution, natural occurrences (e.g Algae blooms) and acid rain, and it is imperative that eternal monitoring of o ur water systems is undertaken to be able to act proactively and swiftly to any changes. (Environment Agency, 2014). When considering the results of our analysis, we can see similarities on pH and dissolved oxygen, (Table 1 and table 4 respectively). Both these chemical properties give a clear recital as to the health of the water systems being analysed. A high pH in the seawater sample for example could suggest an increase in acidification, or pollution in the freshwater should a high pH have been found, especially in an area of high industrial manufacturing such as Stockton and Middlesbrough.The most noniceable difference between the samples was the salinity of seawater against freshwater, (Table 2). As one would expect, seawater salinity is considerably higher overdue to the output of weathering of the Earths surface being transported into the oceans. This makes the ocean a different habitat than that of freshwater. Conductivity increases as salinity increases, however this wa s not found in our analysis. One possible reason could be the era that the sample took to be analysed and the sample temperature as these factors could have affected the results. (SCOR/IAPSO Working Group 127, 2008).Nitrate content was lower in seawater. Nitrates are a naturally occurring compound in the water system whether fresh or sea water. However the slightly higher levels of nitrates shown in freshwater could orient anthropogenic influences due to farming. (World Health Organisation, 2011) High Nitrate composition is also harmful to health as this could cause methemoglobinemia. Nitrates reduce the ability of blood cells carrying haemoglobin resulting in infant deaths. This would also add weight to the higher levels of Phosphates present as it has been suggested that Phosphate increases could be attributed to fertilizer usage and to a higher place the levels suggested as acceptable. (White Hammond, 2006).In Summary, the water chemical composition of both freshwater and sea water in general fall within normal expectations and are good indicators of the quality of the water system within an industrialised zone. The surmise that there is a chemical difference between the two sample types, freshwater and seawater was proven if only somewhat marginal. Further testing for different chemical composition could find a different result. transactionChemical differences between saltwater and freshwater.The major difference between fresh water and salt water is salinity. Freshwater has little or no salt content (The chemical composition differences between seawater and freshwater can be outlined in order of abundance in table 8. (SCOR/IAPSO Working Group 127, 2008)Table 8. Chemical composition of seawater and freshwater in order of abundance.Dissolved OxygenDissolved Oxygen concentrations, (DO), in water is an important factor for all aquatic life. Should DO levels exceed 110%, it can become harmful to marine life and could case the blockage of gas exchange in wh at is known as gas bubble disease, whilst water that has a DO of little than 5mg/l or lower over a longer stop consonant of time can result in fish kills on a large scale and puts stress on all aquatic life.

Critical Analysis of Theme for English B Essay -- American Literature

When I first read Langston Hughes poem Theme for incline B, I did not particularly like it. But after(prenominal) reading it a second time and discussing it in class, I came to prise the poem on several levels. The way Hughes describes the setting of Harlem/New York is brief, that evocative. He also gives us insight into the thoughts and emotions of the main character, the young biased student, and ends the piece with several thought provoking passages. In the first stanza we bring the student, who is also the narrator, having gotten his crime syndicatework assignment to write a paper, is returning home to Harlem. The school he attends is on the hill (line 9), and apparently is in a better part of town, so he has to travel through the variant areas of the city. The streets he crosses are named, and then he gets to the Y (line 13). The usual intend of a Y is a point in a way that splits in two directions. In this case, though, it refers to the YMCA, where the stud ent lives. I think the causality is aware of this double meaning, because in the next line he clarifies the bourne by...

Despite the pass off prohibitions against child-murder by all study religions, female infanticide has been for centuries a prominent and kindly acceptable event, notably in one of the most populous countries in this solid ground, India. Even today, the extent of the difficulty is measured in alarming proportions all around the globe at least 60 million females in Asia are missing and feared dead, victims of zipper more than their sex. Worldwide, research suggests, the number of missing females may top light speed million. The data is more astounding in India. According to the Census survey of 2001, for every 1000 males the number of females has decreased to 927 in 2001 from 945 in 1991 and continues to decrease. It is clear that the burdensome costs involved with the raising of a girl, eventually providing her an take over marriage dowry, was the single most important factor in allowing social acceptance of the murder at comport in India. Nonetheless, in admission to the dowry system, the reasons for this increasing trend have also been attributed to the patriarchal society, leanness and the availability of sex-selective abortion. Indias population growth has been rapid, resulting from longer manner expectancy and glower infant mortality in recent decades. Before independence, the high birth rates were balanced out by high death rates. In the half century since India gained independence from Great Britain in 1947, the average life expectancy has risen from just 39 years to 63 years, as high as that in Russia today. Conversely, after independence, the numbers changed but mortality rates dropped without a matching drop in birth rates. The experience of children became very different. The urban poor contributed most to the population and the reason for this is that they started reckon children as sources of in strike rather an investment. They were seen as an old age warrantor and the more the better. Furthermore, even though the mortality rate dropped, it was still comparatively high compared to the survival rate. For this reason, fear of child death and contagious diseases caused the urban poor to contribute even more to the ever-increasing population. Part of the reason India is gaining on China as the most populous country in the world is that China has had very severe family planning laws, enforcing a one-child-per-family policy on most of the population.

Before 1951, the capability of growing cells resulting from animal tissue remained indefin suitable. The cells would die forwards they could reproduce for research. This changed in 1951 when a woman by the name of Henrietta Lacks was biopsied because of a tumor. She later passed away due to her cancer. The cells were taken from her cervical cancer cells and straightway thrive on their own.While the cells of Henrietta Lacks became commercialized, the Lacks family was forced to live without healthcare. They lived their lives in poverty. Henrietta Lacks horizontal surface is about her involvement to medical research. The problem with all of this is she never gave the indemnify permission to take her cells. Doctor George Otto Gey took them from her cervix. She then died from her cancer. I believe this was prostitute you should have the right to know if a doctor took a expound of your body. Henriettas family didnt find out about what Gey had done for a while after it happened. I thi nk they deserve some payment for the HeLa cells they lived in poverty, even though Henriettas cells were making so numerous advances in science. They shouldnt be given all of the profit because they were not doing any of the work to make the advances, but a little something should be given in honor of the doctor taking the cells.There has alike been a theory for racial minorities. Henrietta Lacks was black and some people believed that what had happened to her may have happened to many other people. If doctors took samples of her body, they would probably do it to anyone else. In the 50s I dont think they were necessarily doing it because she was black, they did it to everyone, black or white. In the 70s, when scientists went back to her children to do research on them. Thats the ... ...ical cancer caused by this virus. analyze her cells allowed them to see how this virus light-emitting diode to cancer and found that the virus inserts desoxyribonucleic acid into the host. Thr ough this knowledge they were able to create a vaccine that blocks the HPV DNA. This is a prevention method.Polio is a viral disease that affects the nerves, it leads to possible paralysis. HeLa cells led to a vaccine that is about 90% effective. Henrietta went to johns Hopkins and today polio is a rare disease. It is all thanks to the cells of Henrietta.Due to a tragic err made while mixing HeLa cells in research, scientists were able to finally bring out a count of how many chromosomes human cells were supposed to contain. This mistake allowed chromosomes to tumesce and be clearly visible compared to the clumped appearance they normally have. Using this scientists were able to start diagnosing genetic disorders.
