NoLag product

For the different budgets related to the NoLag product of JetSet Travel, Inc. (JTI), I would expect to see different items. Below are said budgets and items. But I would like to define what budget is first. Horngren, Datar and Foster (2002) defined budget as the â€Å"[quantitative] expression of a proposed plan of action by management for a specified period and is an aid to coordinating what needs to be done to implement that plan (p. 835). Sales budget. This is usually the staring point for budgeting. The budgeted sales for a future period determines the production and inventory levels which also determine the manufacturing costs of JTI as well as its nonmanufacturing costs for its NoLag product. Items seen in the sales budget are the budgeted selling price for the product, budgeted number of units to be sold, and of course, the budgeted total revenues fro the product. With respect to costs behavior, the items shown in the NoLag sales budget are all variable. That is, these items changes in total in proportion to the number of products to be sold. Purchase budget. This budget identifies the direct materials to be purchased which depends on the budgeted usage of direct materials. Items seen in this budget are the direct materials needed, and under each material the following are specified: Direct materials usage for the period, Target ending inventory for the direct material, Beginning inventory for the direct material, Cost per unit of each of the direct material requirement, and Budgeted direct materials purchases for the period The direct material cost, specifically the direct materials purchase cost is a variable cost. The amount changes relative to the number of direct materials budgeted. Operating expenses budget. This budget included the nonmanufacturing costs related to the NoLag product value chain. Included in this budget are research and development, marketing, distribution, customer-service, and administrative costs. The research and development costs’ behavior – fixed or variable – depends on how management allocates funds to it. If management decides that 10 percent of the total sales budget is to be allocated to research and development, then it is variable – it varies according to the sales budget. The rest of the items under the operating expenses budget exhibit the same characteristics. For example, marketing costs are usually budgeted as a percentage of the sales budget. Capital expenditures budget. This is composed of the investing requirements of JTI with regard to the manufacture of the NoLag product. The expenses here are fixed which includes budgeted purchase amount of new equipments. Cash budgets. The cash budget, according to Horngren, Datar and Foster (2002), â€Å"is a schedule of expected cash receipts and disbursements† (p. 197). Generally, the cash budget has several main sections. Beginning cash balance AND cash receipts. These will form part of the cash available for financing requirements of JTI. Cash receipts come from collections from customers and sales of the NoLag product. Cash disbursements are composed of direct materials purchases, direct labor and other wage and salary outlays, interest on long-term borrowing, income tax payments, and other costs and disbursements. Short-term financing requirements. JTI needs short-term financing requirements if its total cash receipts for the period are less than its total cash disbursements. Ending cash balance. Include considerations for the variable aspects of this product and its sales References Horngren, C. T., Datar, S. M. & Foster, G. (2002). Cost accounting: A managerial emphasis.

An Analysis of the Dynamic Customs Union Theory Essay

Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The idea of a common market came to life with the economic integration of the European nations after the Second World War. The question thereafter lies whether the efficacy of this decision is quite effective or is working for the benefit of their common market.   In addition, the application of the ideas herein will be discussed with dissimilar analyses of the factors that discuss the economic implications of the regional integration. X-Efficiency Analysis There are a number of unlike potential efficiency effects of consolidation that may be able to be applied to either domestic or international M&As. In the current European Stock Market for example, we review the existing empirical research on a number of these types of efficiency (De Young, 2000). We include the scale and scope efficiency effects of M&As that increase the size and the count of different types of services offered by consolidated institutions. We also include several X-efficiency effects, or changes that move the consolidating institutions closer to or further from their optimal points on the best-practice efficient frontier. Specifically, we consider the X-efficiency effects of geographic diversification and managing from a distance, and the X-efficiency consequences of the M&A process itself (De Young, 2000). For all of these types of efficiency, we consider both cost and revenue efficiency effects, and often include research on profit efficiency, which incorporates both cost and revenue efficiency. For some of the types of efficiency, a change in the risks of consolidating institutions is also a consideration, because the risk of the consolidated institution affects its costs of funds and its ability to raise revenues. The research is drawn from many countries, including most of the European countries, although most of the studies use U.S. data. ‘Dynamic effects’ is the term used in a variety of ways by different authors to cover anything beyond standard comparative statics or any effect that has to do with economies of scale and any effect that tackles technical change (De Young, 2000). Static effects universally estimated at about 1%. With static effects only those resources who move activity gain (if they get re-employed). And gain is equal to the difference between uncompetitive (protected) activity and the new activity (assumed to have Comparative Advantage). Big effects are likely to come from scale economies and especially shift in cost curves. Cost reduction affects all existing production as well. Firms need regulatory certainty that they will get market access. Hence, incurs a lower risk premium on investment – in other words, growth effects Terms of Trade Effects Other than the import regulations, industrial organizations also differentiate the consequence of import raise effects on the stock markets in the European Union. On the other hand, the course of the effect of import raise on focus is unclear. A study points out that the effect of imports on producer concentration is positive. Probable reasons of the raise in producer concentration ratio are the absence of inefficient firms as a result of import liberalization. The other possible reason is the increase in mergers of domestic firms as a result of import threats. In addition, if imports are close substitutes for domestic production, sectors that have high import share may be expected to be characterized by a high degree of defensive concentration. Alternatively, it is also likely that imports would reduce concentration if producers were induced to improve efficiency and in turn increase the number of efficient firms. In the same way, the result of the increase in exports on producer concentration is also unclear (Nagy, 2005). There is a positive relationship between export increases and concentration if an increase in exports reduces average cost because of scale economies from increased market size, and as a result producers engaged in exporting activities should be able to increase their market share. Because a larger market size resulting from export opportunities can support more producers, a negative relationship is more likely if the economies of scale in production or distribution are not that important. Paralleling these theoretical developments in the industrial organization and international trade theory, there are a number of empirical studies examining the effects of trade liberalization on the price-cost margins. The result of the studies point out that an import increase has a negative impact on the price cost mark-ups of highly concentrated industries. The EU is an exception to these studies because it suggests that there is no systematic evidence of the import discipline hypothesis for the EU economy (Nagy, 2005). Regarding the pro-competitive effect of economic integration, a study of Bottaso confirms the view that economic integration reduces the price cost mark-ups for Italy and Spain. The idea of a free custom union around Europe emerged in 1950 as Customs Unions and Free trade areas have been seen as a step towards global free trade. This was previously supported by a provision on GATT 1947 Article I that required non discriminatory â€Å"MFN† trade. However, Art. XXIV allowed CUs/FTAs covering â€Å"substantially all† trade and if overall degree of protection was no higher although the provision was not well defined as it created a further dilemma particularly on the implementation stage of the process. Krugman argued that dividing the world into 3 blocs was worst possible outcome through impact on those excluded but later said benefits of deeper integration positive when â€Å"Natural† Blocs form. Kemp and Wan 1976 showed that any customs union could be welfare enhancing if the right tariff taxes and subsidies were adopted.   But high tariff CUs can have adverse terms of trade effects on an EU member’s partners and on trade partners. â€Å"Deep integration† can credibly ensure trade barriers not replaced by â€Å"domestic† measures:   trade barriers now often â€Å"non-border measures† and change business expectations. Economies of Scale Analysis Recent academic studies regarding international trade gives us specific gains from trade derived from theories both from classical and neo-classical economic approaches. Among what these theories suggests is the pro-competitive effects of trade liberalization with the emphasis on the expansion of the market size in terms relative to the change in the number of firms that are present. Consequently, the pro-competitive effects advocate that trade differentiates the intensity of competition in the market; including the company’s price cost mark-ups, their relative scale and production output. New several theoretical readings regarding international trade have had several implications upon the European Union economic customs integration. The purpose and significance of the welfare services involved in the new theory applied to the regional economic integration has widened the range of possible benefits from the European Union countries’ integration further than that put forward by the standard customs union theory patterned on a perfect competition structure and constant returns to scale (Akkoyunlu-Wigley, 2005). Accordingly, one of vital issue is that customs union theory concentrates more on the outcome of the economic integration rather than the market structure efficiency and the productivity of firms. For that reason customs union theory is not anymore viewed as one theory subsequent to the classical Vinerian ideas of the conception of trade and trade diversions. It is often debated that the pro-competitive aspect of trade liberalization is suitable under both the theory of monopolistic competition and the oligopolistic market structures. Obtained on the assumption of monopolistic competition, it is illustrated that trade liberalization leads to an increase in firms scale and decrease in average cost and prices by increasing the elasticity of demand. Likewise, under the theory of oligopolistic interaction between the European Union member countries, trade liberalization also creates a decrease in price cost mark-ups and produces an increase in the overall firm scale by heavily moving the market power of the firm in home markets (Akkoyunlu-Wigley, 2005). With respect to the pro competitive implication in the case of customs union, the significance of the pro-competitive effect as one of the outcomes of customs union and propose that regional ones, such as the European Union oppose global unions that will then intensify the pro-competitive result. Specifically, due to the production shifting effect, the exact figure of firms in a country that would boost the integrated area involved which in turn would reduce the home market shares of companies in the European Union. Alternatively, new empirical studies also show developed industrial organization theories that test the implications of trading on the current market structure as well as profitability. The â€Å"import discipline hypothesis† within the framework of the SCP paradigm is being tested as far as import liberalization is concerned. Then again, industrial organization theory also looks onto the implications of imports on price-cost margins (Akkoyunlu-Wigley, 2005). Similarly, an increase in imports of EU countries for instance as a result of trade liberalization would cause a decline in the price-cost margin by means of reduction in the market power of domestic firms or through the increase in competition. Also, since the competing imports will increase, the number of alternatives available to domestic consumers will increase and may raise the demand elasticity and therefore reduce the price-cost margins. Likewise, the other countries that have an interest in replicating what Europe had done may not necessarily run after the economic integration just so to experience the benefit it curtails. Some countries may not really have to. Instead, what governments must do to replicate the benefits without risking much of the variable discussed is through the multilateral cutting of the tariffs that the involved countries may have on certain products that either one or both of them produce. The concept of competitive advantage enters here as the devaluation that would follow suit which would create and ensure a full employment for both countries involved. Growth Effects Analysis The first systematic albeit descriptive investigation of output effects of economic integration was carried out under the heading â€Å"dynamic effects of integration†. According to Balassa these dynamic effects are rooted in internal and external economies of scale, faster technological progress as a result of economies of scale in the R&D-sector, enhanced competition, and reduced uncertainty, the creation of a more favorable environment for economic activity and lower costs of capital due to the integration of financial markets. The revival of growth theory in the mid-80s led to a more formal reconsideration of the effects of integration on growth and shed more light on the questions involved (Badinger, 2001). At the outset, a terminological clarification is in order here. The most important distinction relates to the persistence of the effects of economic integration on the growth rate: Permanent growth effects lead to a change in the steady-state growth rate, resulting in a steeper growth path of the economy. On the other hand there are temporary growth effects (or level effects), which cause only an upward shift of the growth path, while leaving its slope unchanged in the long-run, i.e. after the transition period the growth rate falls back to its steady-state level. Following the level effects can be further subdivided into static effects that lead to more output from the same amount of inputs and dynamic effects that â€Å"influence the accumulation of factors†. Also referring to the channels through which growth effects materialize the terms â€Å"integration-induced technology-led growth† and â€Å"integration-induced investment-led growth† (Badinger, 2001). Although first used in the context of level effects, this distinction equivalently applies to permanent growth effects. To analyze the consequences of integration for economic growth in a systematic way, two lines of theory have to be distinguished: neoclassical and endogenous growth theory. In neoclassical growth theory, economic integration and other institutional aspects or economic policy measures have no effect on the steady-state growth rate, which is solely determined by the exogenous rate of technological progress. As a result of diminishing returns to capital the capital stock and output per efficient worker grow only to the point where the investment ratio equals depreciation plus the rate of technological progress (for constant labor). (Badinger, 2001) The growth of capital stock and output per worker in equilibrium is then given by the constant rate of technological progress (g). Institutional changes, increases in efficiency or changes in the investment-ratio have only temporary effects on the growth rate; after a transition period it falls back to its steady-state level. Thus, neoclassical growth theory clearly rejects the hypothesis of permanent growth effects. Nevertheless, both static and dynamic level effects occur. Static effects arise from three main sources: lower trade costs, increased competition and enhanced factor mobility. This increase in efficiency leads to more output from the same amount of inputs in a first round (static effects). But this is not the end of the story. Given a constant investment-ratio, the increase in output also leads to higher investment and an increase in the capital stock, which in turn increases output in a second round (dynamic effects). Conclusion The European Union is the concern over the effects on competitiveness of the member countries when it comes to pricing behavior and market structure. The European Stock Markets indicate that the higher the volume of trade the lower the price will be and the price cost margins as well as industry market power. It is then safe to assume that the liberalization of trade would eventually cause gains in output and welfare. However, articles on trade liberalization bring out flaws regarding the effects of custom unions about the ability to raise trade volumes on the market structure and price cost margins of industries. Studying the implications of key variables involved, related indicators on the European Union member countries after the implementation of the customs union between the 1950’s and to date, it can be concluded that the volume of the internal trade within the manufacturing industry of EU member countries significantly increased on the average. Furthermore, the price cost and concentration ratios of the manufacturing industry declined on the average during the same time frame. As we examine the relationship that is causal between the increasing volumes of trade with EU countries and the decreasing cost of price margins as well as the concentration ratios of the manufacturing industry sector.   Price cost margins and concentration ratio equations will then use trade ratios with EU countries as explanatory variables in order to interpret the results obtained.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Results on estimation that are presented in this paper present the effect of pro-competitive increase in trade volumes of the EU member countries. We then estimate the price cost margin equation to illustrate an inverse relationship between the margins and import ratios. This implicates a theory that when there is a rise in import to the EU countries after the creation of a customs union would then create a competitive effect and would cause the decrease in price of cost margins within the manufacturing industry. Such an inverse relation supports the point that trade volume increases and export levels within EU countries are forcing the companies in the manufacturing industry to implement lower price cost margins (Breuss, 2001).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Generally, it can be said that the creation of a customs union and the rise in the levels of trade volume within European Union countries seemingly illustrates an increase in competitive gridlocks which will end up in falling price cost margins in certain countries. At the same time, putting an emphasis in the manufacturing industry, positive implications of trade liberalization in the aftermath of the establishment of customs unions is also supported with the results of the estimation schemes intended for the concentration ratio equation. Furthermore, a negative strong correlation can be found between the import variables and the Herfindahl concentration ratios. The concept suggests that raising outputs as well as the imports to the European Union will bring down the marginalized concentration ratios and seclude the market power in the manufacturing industry.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Also according to the results of the estimation method, it would look like that there is no direct relation between the export variables used and the concentration ratios for the manufacturing industry. Furthermore, the concentration ratio equation estimate directs that unobserved time which is previously deemed insignificant and the invariant sector specific factors are as well responsible for the variations in the concentration sectors.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In total, still according to the estimation results, it can be suggested that the increase in trade volumes brings about beneficial implications on the European Union economy as a whole after the custom union period through the increase in competitive pressure coming form other EU member countries as well as the one for falling mark-ups on prices of consumer goods and market power. Therefore, it would be then be concluded that implications on the welfare side of the economies involved are results of varying changes in the pricing behavior as well as the entire market structure of the European Union member countries.

Case Study - Essay Example Edward Alexander wants to invest in real estate, thus building equity based future. He believes that increasing his return would be best done by managing his own investment. He thinks that paying someone for rent is a not a smart idea since it’s simply a waste of money. Alexander wants to invest in the popular Beacon Hill area and thus he initiated a thorough search about the area. He found out that the value of the area is increasing rapidly due to the natural advantages surrounding it such as Charles River and public parks. The properties were listed in the market from $299,000-2.4 million dollars. The rent for a one bedroom apartment in that area ranges between $1100-1600 per month and the two bedroom apartment ranges from $1600-$2100. Alexander has $80,000 cash and the required investments about 21.5%. Thus, Alexander needs $70,000 in cash. Alexander decided to invest in a complex priced at $350,000 that needs renovation of $165,000, he decided to invest his $80,000 and get a $19,000 from an investor and take a mortgage loan of $450,000. Taking into consideration of miscellaneous costs and fees that totaled $549,000, consequently, a mortgage higher than $450,000 would result in a higher interest of $2000 during renovations. This paper will analyze Alexander’s options with regard to this property. And provide forecast of the most important financial ratios. The cases regarding to Alexander Edward, who is a graduate from Harvard College, and recently working in a biotech firms since four years. Due to the good knowledge of the location, and his perspective to give a hand in real estate business included their urge to have a home a good location, he started to explore the location with all possible sources. The business in the sector is on its peak and growth is very good since last ten years. The home liked by Alexander is almost priced at $500,000

Schedule and Cost Control Techniques - Quality Essay

Schedule and Cost Control Techniques - Quality - Essay Example However, from the perspective of the project management, total quality management poses a slightly different orientation. Quality in terms of project management means "project management technique or strategy that is implemented to assure that an awareness of quality is embedded in all phases of the project from conception to completion." (http://www.project-management-knowledge.com, 2008). It is believed that implementing quality in service oriented organizations as well as the project management is trickier in comparison to the manufacturing concerns mostly due to the measurement issues related with the quality (David A.Waits, 1994). However, despite that organizations and project managers are continuously stressing on the use of quality measurement tools for project management so that a consistent level of performance is achieved which is comparable with certain standards of quality. Insuring a good quality in project management requires that certain key areas are taken care of before implementing the concepts of quality and expecting the results which may be exceeding the expectation. First and foremost, it is very critical that quality assurance within the project management must get the commitment from the top management. Top management of the organization must have the ability to plan for the quality in project management but also have the required willingness to provide the resources to the project managers to deploy the necessary resources required to make the quality an integrated part of the project management. Further, top management of the organization must review the progress made against the set standards for the project management and must have the ability to reward the appropriate successes made in achieving the required quality standards for projects.It is also important that in order to achieve the quality in project management, the employees' em powerment is the key. This empowerment is achieved through the training and development of the members of the project teams. Further, empowerment can also be achieved through initiating the culture of appreciation and rewarding the genuine successes made towards achieving the required quality within the projects as well as through the various suggestion schemes so that the members of the project management team should feel themselves as part of the project as well as the whole organization. This can create strong stimulus for the project management team to deliver beyond the expectations of the management while achieving and maintaining a defined level of quality also. In order to achieve and maintain quality within the projects, it is very critical that the decision making is based on the facts and not made out of the emotions or guess work. As we have been discussing the various techniques of project management such as PERT and CPM, it is of the highest importance that the data provided for calculations made with the help of such techniques are correct and that the decisions made by the project managers at the various stages of the project are made inconsistent with the available facts and figures.

CIT Summary and Response Paper - Essay Example For that reason, therefore, the principle of common good seeks the good of all members of the society, as opposed to the selfish interests of the individual members of the society. The common good can be understood analogously as the social and the community dimension of the moral good. This is because just as the moral actions of an individual are accomplished in doing what is right, the actions of a society attain their full stature when they bring about the common good. Every human society that is aimed at serving its members should ensure that it guided by the principle of the common good. This is because human beings cannot find fulfilment individually, i.e. in isolation from other people; the happiness of the individual members of a human society is dependent on the common good of the society. For this reason, therefore, every member of the society should commit themselves in seeking the common good of the whole society. The principle of the common demands respect of the human person and his fundamental rights; the principle of the common good, therefore, demands that there should be peace and justice in the society. This is because peace and justice are a necessary conditions for the respect of fundamental rights of the human rights in the society. A community with the principle of common good, therefore, should ensure that its members are able to meet their basic needs, and that they are guaranteed their fundamental freedoms/liberties that respect their fundamental rights. Although common good is quite import in every society and every member of the society should seek it, attaining the common good, however, is not easy. This is because common good requires that we should seek the good of other people as if it were our own good. Since every person in the society has the right to enjoy the social conditions that are brought about by the quest for common good, there should be social justice in the

Discussion Board Case Study Example | Topics and Well Written Essays - 500 words

Discussion Board - Case Study Example As a reader, the immediate question that comes to mind seeking clarification from Driscoll is why he characterizes as feminine all the things he identifies as evil, dirty or weak. The book makes apparently misguided and poorly translated references to the biblical book of first Timothy about the role of senior pastors not belonging to women. The actual writings simply state that women can only ask questions after the church service is over but does not explicitly bar them from taking on leadership roles. Agreeably, the teachings of the bible should guide the activities of the church and more so, the leadership style. But, on the other hand, Driscoll must understand that times are changing and including women in leadership positions is inevitable. From the context of his book, he needs to clarify to the reader that he is actually not objectifying women. He clearly acknowledges that the head of the Church is Jesus and elders are made up of human leaders who follow in his footsteps and get others to do the same (Driscoll, 2008). Then, with such understanding that leaders are humans, why exclude women? Why would he go further to claim that he was specifically called by God to train men and not women? It is ironical for Driscoll to say that it is a sin for any Christian not to actively love their Christian brothers and sisters as faithful church members, yet segregate them on gender basis. Why would he say that human leadership in the church is about qualified Christians that follow Jesus and encourage others to do the same but still believe that women do not have the qualification? When he likens leaders to good sheep that follow their shepherd Jesus Christ, what rationale informs him that women are incapable of following the teachings of Jesus? When he talks of Paul teaching Christians to be imitators of him as he was of Christ, does he not realize that Paul was addressing

Dune Essay Example | Topics and Well Written Essays - 500 words

Dune - Essay Example The Bene Gesserit sisterhood also had superhuman powers, when using melange, a popular spice, to awaken genetic memories of their ancestors. During this backdrop a politcal struggle between three fuedal houses erupt. These houses were the Imperial House Corrino, and two lesser Great Houses, the Atreides and the Harkonnens. Shaddam IV, the Corrino Emperor, felt that Duke Leto Atreides of the Great House Atreides was becoming too popular. Baron Vladimir Harkonnen aided the Emperor in defeating the Atreides. They send the Duke Leto Atreides’ Great House to a planet Arrakis where Melange is grown. After removing the Duke from his planet of power, the evil forces against him attack. When trying to assasinate Baron Vladimir Hakonnen, Duke Leto is killed. After Duke Leto’s death, his son, Paul Atreides, and Paul’s mother, Jessica, escape into the desert. Because of Jessica’s ablities as a Bene Gesserit, plus Paul’s abilities as her son, they join the desert tribal group of the Fremen. Paul becomes the messiah, or political and religious leader, of the Freman. Paul then uses the Freman warriors to take control of Arrakis and the spice trade of the Melange, forcing the Shaddam IV to abdicate so he could become emperor.. The political theme in Dune revolves around a fuedal system like in Medevial Europe. There are Lords, Vassals, and Fiefs. The Lords or nobility are the Three Great Houses, Vassals are the people working for the nobility, and Fiefs are the planets like Arrakis. Colonialism and post colonialism themes run through this novel also. The colonist, Paul Atreides, rallied the natives, Fremen, to overthrough a oppressive government, Shaddam IV. The religious aspect of Dune is intertwined in the political one. By believing in the Missionaria Protectiva, or contrived religious myths, the Freman are convinced that Paul was not only the messiah, but the political leader as

Effectiveness of HRD Programs (Public and Privet sector) in Oman Dissertation

Effectiveness of HRD Programs (Public and Privet sector) in Oman - Dissertation Example Sadly though, there has not been an effective way of measuring the impact of human resource development in Oman. Once this continuous, it becomes very difficult to tell whether or not human resource management in its entirety is effective in the country. Research Questions 1. How well are companies in the private and public in Oman adhering to human resource management practices as outlined for Gulf Cooperation Council countries? 2. How has human resource managers in various private and public institutions instituted the use of technology in the development of the skills, knowledge and abilities of their human resource? 3. How has the present state of human resource development impacted on employee turnover and employee performance? 4. What systematic plans are needed in the human resource development agenda to ensure effectiveness? Aims and Objectives The overall aim of the study is to identify the effectiveness of human resource development in the private and public sectors of Oman . To achieve this overall goal, the following specific objectives will be targeted so that the collective achievement of the objectives will constitute the singular achievement of the research aim (quote). 1. ... 4. To identify new systematic planners needed to lead the pace in what may be termed the new face of human resource development. General Methodology The present research follows the qualitative research method. This means that the researcher is going to dwell on the use of personalised and focused system of data collection rather than the use of numeric indexes that makes the use of complex mathematical calculations and presentations (quote). The need for the qualitative method emanates from the structure of the research questions and specific objectives, most of which are structured with inductive focus. A major advantage that will come with the qualitative method is that the researcher shall have the opportunity of widening the scope of data collection by using not just primary data but secondary data as well (quote). Data Collection Mechanisms In relation to the use the qualitative research method, the data collection mechanism is going to be selected on a basis that shall allow f or the collection of subjective inductive data (quote). In line with this, a structured interview is going to be used in the data collection process whereby open ended questions are going to be posed to respondents. These open ended questions are the type of questions that do not limit respondents on the selection of specified answers but gives them the freedom to undertake thorough analysis of questions (quote). Research Justification Significance of the Study The significance of the study is one that can be termed to be multivariate. This is because the significance of the study cuts across several sectors and involves a lot of people. For instance, by the end of the study, it is expected that human resource

England and the Colonies Essay Example for Free

England and the Colonies Essay The origins of the United States of America can be traced to the colonization of England in the 17th and 18th centuries. Thirteen of the states that are now part of the nation were initially English colonies. However, the relations between England and the colonies were severed when British policies proved to be too oppressive for the colonists. Eventually, the conflict led to the American Revolution, in which the colonies gained their independence from British rule. From the beginning, England and its colonies have differed in terms of social and political climate. These differences contributed in heightening the tension between the two. The colonies were established between the years 1607 and 1733 (Perry, 1989). The first colony was set up in Virginia in 1607. During that time, monarchy still existed in England, but the power of the Parliament in constricting royal authority had increased. This is the reason why the political climate in England was filled with tension. There was always a clash between the monarch and Parliament. When the first colony was founded, James I was the ruling monarch. He had constant disagreement with the Parliament, a disagreement which would eventually worsen with his successor and son Charles I. The tension between the monarch and the Parliament had become worse, prompting a civil war to occur in August 1642. The outcome of the war led to the execution of Charles I and the establishment of a republic. Royal rule was only restored in 1660, with Charles II as monarch (Perry, 1989). The social climate in England was also filled with tension. This was the result of the religious conflict which began during the reign of James I (Perry, 1989). When his predecessor Elizabeth I was the monarch, the Church of England dominated but many people embraced Protestantism. A group of Protestants known as Puritans wanted to remove what they thought was Roman Catholic influence on the Church of England. James I refused to acknowledge the Puritans’ clamor for religious change. During the rule of Charles I, the situation with the Puritans became more intense. William Laud was the archbishop of Canterbury and he promoted unjust treatment of Puritans. Because of his encouragement, many Puritans were fined and put in jail (Perry, 1989). The political climate in the colonies was significantly different from that of England. The colonists did not have a single, central government. They were not ruled by monarchy or Parliament. Those colonies located in Massachusetts, Connecticut and New Hampshire had their own government and set of laws (Perry, 1989). In the Pennsylvania colony, William Penn even supported political freedom (Perry, 1989). This situation left no room for political conflict, as the colonies were left on their own to govern themselves. Hence, the political climate in the colonies was more calm and stable than that in England. It was not until the conflict with England that the colonies were forced to unite and fight the British in war. On the contrary, the social climate is somewhat similar to that in England. Most of the colonists were persecuted in England for their religious beliefs (Perry, 1989). The reason why some of them decided to move to America was because they sought to establish a community where they could freely practice their religion. Unfortunately, some colonists repressed religious preference the same way British leaders did. In the Massachusetts Bay colony, they refused to welcome people who did not embrace the Puritan religion. However, other colonies were more tolerant than others. For instance, the colony established by Roger Williams in Rhode Island permitted people to practice whatever religion they wanted. The same religious tolerance was extended by Penn (Perry, 1989). England and the colonies differed in terms of political and social climate. In England, there was tension due to political conflict and religious intolerance. In the colonies, individual governments avoided political unrest. Just like in England, religious freedom is also repressed in the colonies; nonetheless, this repression is not absolute. Some colonies tolerated differences in religion. These are the differences between England and the colonies. Reference Perry, M. (1989). A History of the World. Massachusetts: Houghton Mifflin.

Characteristics of Real Time System

Characteristics of Real Time System ABSTRACT Scheduling refers to the set of policies and mechanism to control the order of work to be performed by a computer system. process scheduling in real time system has almost used many more algorithms like FIFO, Round ROBIN ,Uniprocessor Multiprocessor etc. The choices for these algorithms are simplicity and speed in the operating system but the cost to the system in the form of reliability and maintainability have not been assessed. In this paper we describe the distinguish characteristics of real time system which can be expressed as a function of time. This paper is also described in the form of a time driven model for a real time operating system and also provide a tool for measuring the effectiveness of a real time |system . For this model ,we have generated a real time system in which we measure a number of well known scheduling algorithms. To meet the real time constraints for scheduling the task different algorithms were used. Most of the real time system are designed using prio ty based preemptive scheduling and worst case execution time. INTRODUCTION In computer science ,scheduling is the procedure by which threads, process or given the access to system resources. The scheduling is mainly concerned with these things throughout: Total number of processes that complete their execution per unit time. Response time: when a request was submitted what amount of time takes when first response produced. Turnaround time: total time between completion and submission of process. Fairness: equal time to each process. In real time operating systems like embedded system the scheduler also perform that the process can meet deadline that is necessary for stabling the system. Schedular are sent to mobile devices and managed by an administrative back end. A common characteristic of many real-time systems isthat their requirements specification includes timing information in the form of deadlines. An acute deadline is represented in Figure 1. The timetaken to complete an event is mapped against the valuethisevent has to the system. Here value is loosely defined tomean thecontributionthisevent has to the systems objectives. With the computational event represented in Figure 1 this value is zero before the start time and returns to zero once the deadline is passed. The mapping of time to value between start-time and deadline is application dependent. Scheduling In a general purpose computer system a scheduler is considered good if it is fair and gives execution time to all tasks equally. When scheduling a real-time system what is most important is that all tasks meet their deadlines and are executed so that any task depending on them, meet their deadlines as well. Types of scheduling Network scheduling DISK Scheduling job scheduling Manual scheduling Multilevel queue scheduling First in first out Process scheduling Process scheduling is divided into four main types 1 long term scheduling which determines which programs are admitted to the system for execution and when, and which ones should be exited. Concept of scheduling in real time system 2 medium scheduling: Which determines when processes are to be a suspended and remain. 3 short term scheduling ordispatcher which determine which process have cpu resources and for how long. Process scheduling in computer operating system is instance of extensively studied problem from operation research which in form of producing a sequence of jobs which must a common resource. all decisions should be made dynamically for example all jobs have to be scheduled and processing time requirements are available at the start of sequence time =0 the new job will not come during processing. if it happens the priviouly computed job is invalidated and scheduling must be started overif is maintained. Now process scheduling in real time system can categorized into two categories: 1 periodic 2 aperiodic Periodic processes: which arrive at regular intervals are called periodic process and aperiodic are those which arrive at irregular. the main difference between real time systems and other computer system have not understood. the time to complete a process is important in all computer systems but in real time response time play a cruicial part in the correctness of the application software Real-time systems are divided into two classes: Hard real -time systems and soft real -time systems. Hard real-time systems are those whose deadlines must absolutely be met and system will be considered to have failed whereas soft real-time systems allow for some more deadlines, at least occasionally, to be missed with only adegradation performance but not a complete failure of the system. In judge a number of existing real time systems we study the DMA cycling ,interrupt processing blocking ang non-blocking. The deadline scheduler gives no reasonable control over the choice of which deadlines are delayed and which lead to unperictable failures result to the impact on reliability and maintainability of the real time system. real process completion is handled by step function in which there is no any value in completing the process after its deadline the characteristic of a real-time system is that correctness is determined not only by what is done, but when itis done, we propose to use a representation of a process completion value to measure the algorithms in real time system. Computational model consists a set of processes every process has a request time R ,Time interval c and avalue function R. Its value function become zero or negative. the value function may be negative at R,not rise above zero the request time R may be future time or past time . if request time r is future time then process is not scheduable but attributes in computations asre load in which current scheduling decisions are made classical algorithms are. Deadline:The earlist critical time in process at each decision point FIFO:The longest request set is executed in process at decision point Random:chosen from the request set and executed stack:the process with the smallest stack time is executed in each decision point SPT:The shortest completion time is executed in each decision point. There are many approaches for utilizing a time driven model in real time system. real time operating system support or modify the value for the process or the set of processes during run time. In this way application designr can set and modify scheduling policy for various systems. For describing these processes we assume primtives to creat and kill processes already exist. There are three real time interfaces Time control primitive: The arguments of these operating systems communicate the information needed to implement the model but the issue is the structure of informative that passed to the operating system. In single primitive each parameter would be flexible but in user might set inconsistent parametres. Scheduling policies: In real time operating system it is compulsory to provide a mechanism to express the scheduling model to implentour model. the system should also able to modify these policies to take advantage or flexibility of the system. Periodic policies: There is one way to describe a periodic policies to using optional arguments in a creative process. The creative Process make new instance of process at a specific node 5 ways for scheduling the task in real time systems. Real time system and scheduling techniques Real time scheduling techniques are divided into two main categories. One is called static scheduling techniqueAnd other is called dynamic scheduling technique. Dynamic may be static perioty or dynamic perioty. Static prioty is divided into two types 1 rate monolithic : rate-monotonic scheduling is a scheduling algorithm used in real- time operating systems with a static-priority scheduling class. [2] The static priorities are assigned on the basis of the cycle duration of the job: the shorter the cycle duration is, the higher is the jobs priority. These operating systems are generally preemptive and have deterministic guarantees with regard to response times. Rate monotonic analysis is used in conjunction with those systems to provide scheduling guarantees for a particular application. 2 deadline monolithic : Dynamic prioty is also divided into two types 1)earlist time first 2)least stack time first System and the task model Each type and unit of work that is scheduled and execute the system as a job. ALL the tasks are taken to be periodic. the system knows all the things about arrival time ,periodexecution time. the task are ready to execute if it arrives the system. IN soft real time system each task has a real positive value. The main goal of the task is to obtain a value as much as possible There are the two conditions if the task succeed the system acquire that value if the task is not succeed the ystem gain less value in a special case like soft real systems the task has nothing a vale Basic requirements of schedulars in real time operating system There are five basic requirements of scheduler in real time operating system Multitasking and preemptable In real time operating applications real time operating system should be multitask and preemtable. the scheduler are able to preempt any kind of task in the system and give the resources to task that the system needs it Dynamic deadline identification With the earlist deadline RTOS should be able to identify the task. deadline information may be converted to prioty levels for resource allocation predictable synchronization To communicate multiple threads among themselves in a timely fashionsynchronization mechanism also reqired and also the abiliy to lock or unlock is the resource to achieve dta integrity. Sufficient perioty levels The real time operating systems must also have a sufficient number of priority levels for effective implementation. Namelypurety,inheritance,ceiling protocol need sufficient prioty levels predefined latencies the timing of system call define the following specifications Task awitching latency :time to save the context of a current execution time and switch to another Interrupt latency:the time elaped between first instruction of the handler and execution time of the last instruction of the interrupt task Dynamic scheduling algorithm: Dynamic algorithm at runtime assign perioties based on the execution parametres of tasks the most important dynamic scheduling with puriotysscheduling algorithms are 1 EArlist deadline first algorithm The perioty of each task based on the value of itsdeadlinethe algorithm is simple and preemptive. 2 ACO Based scheduling algorithms. The ACO algorithms are computational models for the collective foraging behavior of ants . Ant is an agent that generate a path. ANT do not need synchronization. ant moves to the good looking neighbor for the crrent node probabaisatically Time Triggered When scheduling a distributed system using offline scheduling the whole system including the communication is scheduled before the start of the system giving a very rbust system but the cost of adding a new node is high, complete rescheduling of the whole system. To schedule a time-triggered distributed real-time system we use the same techniques as we did with the single processor system, but understandably with more complex graphs. For example we might have a precedence graph, where one task is preceded by several tasks on different nodes. Making a schedule that have a task precede by tasks on several nodes requires more of the system then of the schedule, even the best schedule will fail if the nodes time references is not synchronized and tasks are not executed in time. This requires all nodes to synchronize time with each other. This can be done at an application level like in normal distributed systems, with a common time reference with a communication protocol that handles tim e synchronization TTCAN, TTP and FlexRay to namea few. SUMMARY AND CONCLUSIONS We have looked at the most commonly used scheduling techniques and communication protocols used in distributed realtimesystems. When we started this paper we where looking at doing a survey of everything related to distributed real-time systems,but found that to be a to vast and growing field so we narrowed our field to communication protocols and scheduling algorithms used in distributed real-time systems. During our research for this paper we have been looking atschedulers that are created to work better with the FlexRaycommunications bus or in a similar fashion. We have taken a real interest in distributed real-time systems and are looking forward to seeing the advances in scheduling and communication for distributed real-time systems and maybe one day join the research field our selves. With this paper we hoped to introduce the reader to the problem of scheduling real-time tasks in distributed systems. We presented the different interpretations of the problem and the various opti ons available to the solution designers. Our analysis of some of the existing scheduling algorithms tried to focus on the affect of the specific problem on the choices made in the solution. We hope that what we presented provides the reader with a broad understanding of the problem and a range available solutions. This paper was also aimed at providing the reader with a solid foundation for further research on the subject. Finally, we suggested possible future research directions. References 1 ^ Liu, C.

Evolutionary Developmental Biology Essay -- Biology

Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (MÃ ¼ller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has been exploring the role of the process of individual development and the changes in evolutionary phenotype, meaning the developmental procedure by which single-celled zygotes grow to be multicellular organisms. Alterations in the developmental program frequently cause differences in adult morphology. When these alterations are helpful, they grow to be fixed in a population and can result in the evolution of new phyla. Evo-devo seeks to figure out how new groups happen by understanding how the method of development has evolved in different lineages. In other word, evo-devo explains the interaction between phenotype and genotype (Hall, 2007). Explanation of morphological novelty of evolutionary origins is one of the middle challenges in current evolutionary biology, and is intertwined with energetic discussion regarding how to connect developmental biology to standard perspectives from the theory of evolution (Laubichler, 2010). A large amount of theoretical and experiential effort is being devoted to novelties that have challenged biologists for more than one hundred years, for instance, the basis of fins in fish, the fin-to-limb change and the evolution of feathers. The biology of development promises to formulate a main contribution to these... ...is. Moreover, the relationship between neo-Darwinian evolutionary theory and evo-devo is highly contested (Hoekstra and Coyne, 2007; Minelli, 2010). However, the understanding of evo-devo methods and how the characteristics of the morphologies of different species diverged eventually is still comparatively limited. Craig (2010) stated that this field has obviously contributed to the understanding of genes and, subsequently, the understanding morphological characteristics of evolution in intricate organisms. There has been significant confirmation of evo-devo’s claim that regulatory modifications play an essential role in the evolution of shape. Evo-devo is the process of becoming a conceptual hub for an even larger integration of research areas in organismal biology, including genetics, ecology, paleontology, behavior, cognition, and other fields (Gerd B. MÃ ¼ller)

Albert Einstein :: essays research papers

Albert Einstein March 14 1879 - April 18 1955 Born Ulm, Germany. Died Princeton, USA. Albert Einstein was a very famous Scientist, he was mostly famous for his theory of Relativity. In 1894 Einstein's family moved to Milan and Einstein decided officially to relinquish his German citizenship in favor of Swiss. In 1895 Einstein failed an examination that would have allowed him to study for a diploma as an electrical engineer at Zurich.

Creons Tragic Insecurity in Sophocles Antigone :: Antigone essays

Creon's Tragic Insecurity in Antigone In ancient Greek tragedies at least one character has the misfortune of having a tragic flaw. The flaw usually effects the protagonist and leads to his down fall. Normally, the characters close to the protagonist are all affected by his flaw. In Antigone, by Sophocles, Creon's tragic flaw is that he is insecure. Creon's insecurity leads to the death of many people and to his own downfall. At many times, Creon feels that people are directing everything toward him, when of course they are not. Consequently, he takes action to make sure people take him seriously. He hopes his actions will teach people not to walk all over him and his empire. However these actions are not always the right ones. Since Creon is so insecure he feels that people are conniving against him. When Polyneices was found buried after Creon clearly announced no one was to bury him, Creon completely dismissed the idea that it could have been the gods or a mere woman who buried Polyneices. He said, "There have been those who have whispered together. Stiff-necked anarchists, putting their heads together, scheming against me in alleys."(9) The mention of the word "those" shows that Creon feels many people are out to disobey his laws and make him look bad. Contrary to Creon's belief it was a woman, Antigone, who had gone to bury her brother Polyneices because she felt he deserved a proper burial. Creon's insecurity made him feel that a large group of people were against him when in reality it was only one woman who disobeyed his law. Creon's insecurity blinds his ability to direct order in his country properly. After Antigone buried Polyneices Creon felt he needed to take a strong stand or people would think he would always be lenient toward criminals. However, to achieve this Creon felt he needed to take drastic action against Antigone. He once even said to his son, Haimon, who was about to marry Antigone, "The woman dies. I suppose she'll plead family ties. Well, let her. If I permit my own family to rebel, how shall I earn the world's obedience?" (19) This quote shows that Creon feels that to prove himself to the country he needs to earn the "world's obedience".

Playgroups support and offer valuable opportunities Essay

Playgroups support and offer valuable opportunities for parents to meet and share their experiences and for children to play and socialise. They are coordinated by qualified community workers who give parenting tips and advice and provide information about other community services for families. Expert guest speakers are invited to talk about topics related to parenting or childhood development. Parents are encouraged to become involved in planning and running playgroup activities. Playgroups provide a range of learning experiences to stimulate children’s intellectual growth. They learn about interactions with other children and can develop their communication skills. The community workers can help parents with behaviour-management techniques, provide information for parents about topics such as child development, health, hygiene and child safety. They can also help with developing social networks for parents, and identify developmental problems and refer families to relevant services. BENEFITS FOR FAMILIES Supported playgroups bring a number of benefits to the communities in which they operate and to the people who take part. These benefits areThis is a service that lends toys, games, puzzles and educational aids to families. The items from the toy libraries must be returned at a certain time. At some toy libraries, children are allowed to attend the library to play with the toys there. Leisure library – this provides play materials for adults, especially for disabled adults and families from disadvantaged backgrounds, who have not known the joy of play. Teenagers can also benefit form these libraries, as there is challenging activities that could positively counteract effects of boredom, such as drugs and alcohol abuse. The libraries for children, the toys/resources that are lent, can help children to develop physically, mentally, socially and emotionally. They can learn through play by imitating, exploring, creating, solving problems and sharing with others, (brothers/sisters). Toy libraries promote ACTIVE LEARNING. The libraries also help low-income families who are not able to provide their children with adequate learning opportunities. The parents may not be able to send their child to any form of pre-school centres. Specialist toys and equipment, which can be very expensive to buy, can be available for children who have special needs. Many toys which can be bought at home, end up lying about the house, with the toy library, 1 toy is exchanged for another. Other benefits for having a toy library is that it can help parents learn about and are empowered to provide suitable stimulation for their child. Some may say that parents don’t want to get involved, but the fact is that the parent doesn’t know what to do or how to do it. The toy library could help the children and parents to play together, to share the activities, this would help to strengthen the family unit. Children who are ‘at risk’ can receive preventive stimulation, the toys at the library may be graded, this can help the child make steady progress on their development. The child’s self confidence may increase with each toy, when they master the activity. Therapists report that children receiving therapy and also belong to a toy library, generally improve faster with their development and social well-being. There can be additional services that can be offered by toy libraries, these are names of childminders, schools in the area. Leaflets giving information about organisations, nutrition and different workshops, that are available in the local area. Homestart This is a charity organisation, in which parent volunteers help families and children through rough patches in their lives. Volunteers help all types of parents, mums struggling with post-natal depression, young couples who don’t have any idea of what to do during their babies early years, professional women having difficulty coping with the switch from the structured work environment, to home life and late parenthood. The volunteers provide non-judgement support to allow the people to build on their own strengths. Homestart volunteers set out to end the isolation that parents with young children experience. It offers friendship, practical help and support. They are trained how to talk, encourage, when necessary to guide mums and dads. The parent volunteers create an atmosphere in which families can cope with the pressures they are facing, this can then reduce the potential, for family breakdown. The volunteers can also help families get their act together sufficiently so they no longer need the supervision of statutory social services. E. g. in 2003/4, 822 children whose families were supported by Homestart were removed form the child protection register. The volunteers work alongside parents, not telling them how to bring up their children, but may offer advice if asked. Sure start children’s centres These centres are in the most disadvantaged areas. The services they provide are:- Good quality early learning, combined with full day care provision for children, this could be effective for both child and parents. The child would make friends, learn and develop their skills and their developmental stage. The parents may be able to go out and find work. There are effective links with Jobcentre Plus for training or employment. Their would be support and services to parents and children who may need different services. I. e. special needs. The workers there, give information and advice to parents on a range of subjects, I. e.  childcare, looking after babies and young children, education services for 3 and 4 year olds. They have drop in sessions and other activities for children and parents, this can help parents socialise with other parents, make friends, look at other children and see other children playing, parents playing with their children and learning them to do the same. It can stop parents form being isolated in their home, getting them out and active, letting them discover new activities, learning about themselves and others around them, discovering new hobbies.

Hearts and Minds Essay

Movies and documentaries have a way of touching the lives of many. For the most part, they are geared towards the exhibition of truths that are hidden from other people. The documentary, â€Å"Hearts and Minds†, mirrored the numerous difficulties experienced by the Vietnamese in the hands of the American soldiers. The harsh realities shown by the American soldiers towards the Vietnamese was quite difficult to believe, for we all know how the Americans would care for any other individual. Directed by Peter Davis, the documentary showed different clips that prove the harsh attitude towards people at that time. Even the speech of former President Lyndon Johnson was shown in the said documentary. To give people a great feel of the said timeline, much of the most famous details during that particular time were shown. The type of music, clothes, and even some old archives were shown. In this manner, it would become easier for the audiences to understand what was being explained to them. I admire the montage feeling provided by the documentary. Together with the voice over, watching the documentary was like watching any other historical how. However, what sets it apart from the rest were the heartbreaking realities exhibited. I could not help but wonder as to how people were treated unfairly and how other people could bear causing pain to others. One of the scenes that caught my attention was the funeral of a soldier. Surrounding the coffin were grieving people, including the family and friends. However, for some reason, one grieving lady was stopped from following the coffin being laid to rest. This particular scene was contrasted with a clip showing the interview of the general who led the Vietnam War. Furthermore, there were several other interviews included in the documentary. Although I am not of Vietnamese, origin I was heartbroken by the difficulties experienced at that time. For the longest time, they experienced pain, both physical and emotional, while they struggled to raise their families accordingly. A particular scene exemplified the hardships endured by the Vietnamese during that particular time. The scene showed how the prisoners of the war were sitting restless and not paying attention to what their employer had in mind. I felt pity with the condition these people experienced, toppled by the excessive torture and inhumane humiliations provided by the American soldiers. After watching the documentary, one could not help but question what has been taught in class during our younger days. I was surprised at how the outcome of this war has been, including the participation that the American soldiers portrayed. However, due to the extensive information provided, some critics may also form their own conclusion as to how the said war was used as propaganda. On the other hand, it would be expected that some people would opt to be biased towards the Vietnamese and consider them to be victims of the American occupation. Regardless of everything that has been said, I believe that we all have our own perceptions towards things. Personally, I believe that the goal of this film was to show the other side of history that not everyone was aware of. In this manner, I would be able to form my own beliefs as to how people would be able to learn from these hurtful experiences. It is useless for us to keep on living in the past—we should all move forward in helping make a different in this lifetime. I must say that I recommend this film to everyone, especially those who are currently studying about the history of the United States.

Digital Camera

Technology within the last fifty years has evolved drastically because of the introduction of computers. This technology remains changing, mostly for the better as a multitude of public and private corporations do their research and development to elevate mankind’s way of life into another level of advancement. One most notable change in the people’s everyday lives is the evolution of photography.From bulky cameras, film and hour-long photo development came the instant, flashy, sleek and compact digital cameras that can take photographs and can store them instantly electronically. This paper provides a critique of Thom Hogan’s (2009) article, â€Å"How Digital Cameras Work. † Catching moments and having a souvenir for it are the main points of why people take a photo. People can be sentimental and so, a camera is a gadget that almost every household have. However, there are so many people out there who do not have the zest and passion for photography and t he science behind it.Majority of users do not understand their digital cameras and the author, Thom Hogan, wrote the article to help these millions of people to get to know how a digital camera works and it is often not wise to rely on the adverts or express warranty a manufacturer claims, as more often than not, those claims are not true, scientifically speaking. The opening notes of the article says this much and this is a catchy enough way to get attention of even uninterested users.The main concern about the article, is that, even though it is written for people without photography background, the terminologies used seem to be strictly for photographers. For instance, a lot of average users of digital cameras do not know the difference between 28mm vs. a 35mm cameras and the author used the â€Å"35 mm† term as though everyone would understand what it means. The author could have set up a terminologies page to help the average users understand the article better. That bei ng said, this paper shall now discuss the rest of the article.The author tackled first the functions of a camera’s sensor. This is of course the silicon chip on a digital camera which has two kinds: CCD and CMOS. CCD and CMOS are explained by author in the next part which is a smart move considering that this article can be used for basic digital photography and some technical terms must be already infused. CCD, according to the author, is an old technology while CMOS is the sensor of today and this sensor shall be the one referred to for the rest of the paper.The author mentioned one brand that designed a good CMOS sensor and that brand is Nikon. Such mention of brand can raise eyebrows as one would think whether this particular author has been paid by Nikon to advertise the brand’s sensors on a variety of users, after all, who is better to trust than an expert in photography? Next, the author mentioned photosites within the sensors. Photo diodes are the light sensing portion of photosites and they cannot cover the entire sensor as there are â€Å"non-light responsive spaces between diodes†.This statement by the author can be considered a fair warning to digital camera users. As early as this stage, they know about the limitations of digital photography, that not all sensors are good at sensing light, which is essential in taking photographs. Again, the author endorsed Nikon and Fujifilm cameras as exception to the sensor rule. He described how certain Nikon and Fujifilm sensors (actually named camera models) have overcome this limitation in digital photography. The author proceeded to describe light and sensors the way a physicist would.This is again more confusing to the average reader or even photography novices. Next, the author mentioned that a camera sees in black and white and he described how cameras produce colours in different ways. The different ways the author described are wonderful insights into photography and it can get us ers more valuable information on how they would like to use their camera sensors. More people tend to prefer photographs with vivid colour. Lastly, the author described how to get data from the sensor of a camera.Essentially, he told users the more manipulations done to a camera, the more the image gets further from its original form (adjustment of colour, brightness and even simple JPEG conversion). This is another essential information as some user prefer realistic images over bright colours. Overall, the article is highfaluting one, especially for normal, average user with no inkling for photography but it provides valuable information to those with photography background and would like to know more about the art.

Operation Management - Dubai International Airport Term Paper

Operation Management - Dubai International Airport - Term Paper Example A look at the advantages of TQM reveals that it has been able to be more important than its disadvantages and as such is rapidly being adopted by most firms (BANK, 2000). This study for that reason, sought after examining the application of total quality management in the operations of Dubai International Airport in relation to the following key themes or concepts: globalization, cultural organization of the airport, the decision making process used by the management, relations of financial forecasting and its techniques to TQM, emergency, safety and security, economic significance, and infrastructural developments within the facility (MUKHERJEE, 2006). Introduction Dubai International Airport is an international airport that serves Dubai. As a major airline hub, the airport serves the Middle East as a main airport. This airport is also the home base of most of the international airlines in Dubai such as Emirates, Fly Dubai and Emirates Sky Cargo (HUGOS, 2003). Other international ai rlines have also lined up to be operating from this airport and as such it is an extremely busy airport in the Middle East compared to all other airports. In a month, this airport operates hundreds of thousands of passenger flights to several other destinations in the world. The airport is spread over a large piece of land spanning up to 3500 ha (BOERMEESTER & DURANTE, 2000). The airports ability to handle this huge passenger traffic made it to be ranked the 3rd busiest international airport by international passenger traffic thus, surpassing Hong Kong International airport in the rankings (LI, 2013). Research questions The following questions were the guiding points of this study. i. What effects does the adoption of total quality management by Dubai International Airport have on its operations? ii. What total quality barriers do the organization face in its operations if any? Purpose and significance of the study The purpose of this study is to establish the relevance of total qua lity management policies within the operational actions of Dubai International Airport (REID & SANDERS, 2007). The results of this study are anticipated at benefiting the Middle East economy with regard to airport supervision by contributing to the improvement of knowledge and understanding on the subject area both hypothetically and practically (KETCHEN, 2007). It shall also form the basis on which other researchers can build up their studies in the equivalent or related field in the future. Objective of the study Based on the study’s statement of the problem and the research questions, the validation of this study will based on the main purpose of establishing the impacts of total quality management on the operations of Dubai International Airport and whether these quality management policies have had any influence on the growth trends witnessed in the organization (HANSSON, 2003). Scope of the study The study is prearranged to be conducted during the semester as part of a partial achievement of the course requirements. The study shall be structured into a number of chapters with wide-ranging coverage of the sub-topics done under each chapter. Consequently, the scope of this study shall be restricted to date from the year 2000 with Dubai Internation

POLITICAL EXPERIENCE ANALYSIS Essay Example | Topics and Well Written Essays - 1500 words

POLITICAL EXPERIENCE ANALYSIS - Essay Example In effect, whether it is to protest some program of the government or to display your endorsement for a specific contender is known by all that majority of rallies achieve nothing. For oppressed cultures, where injustice is the order of the day, the rally has the opposite effect. Put it another way, there is nothing more powerful that thousands of people making the simple demand of, say, liberation. The odd successful rally in recent-day America invariably is a response to the attendance of coercion or inequality. During spring, I attended a rally for Barrack Obama in Ewes, Iowa. Preceding that experience, I had never attended any rally. I am in University. Obama’s rally at Iowa State University was promptly organized by some assiduous group. Why did I feel the urge to go? To put in another way, I was quite startled. This rally provided an opportunity to contribute in a time-privileged student tradition. I believe that the presence of some rally along the path of life is archetypal to the experience of any young man who is semi-educated and has the jot of political opinions. In a sense, this belief was accurate, just because is function to show the imprudence of swinging out of old political varieties for new time. It was a hot dreary day, as nature has added brushstrokes to the atmosphere to emphasize the farce of the attendees endeavor. We all stood around underneath the steps of the University’s Agricultural Building, and attempted to think ourselves as the re-embodiments of activists protesting at that very spot against the military’s Don’t Ask, Don’t policy and Obama’s abortion rights stance. A man got to his feet at the top of the stops and started shrieking into the microphone to get the rally going. The first few epistles were met with a proper amount of fervor mixed with ire. However, I had not expected to enter some arena of political thoughtfulness nor seriousness. But this one proved me wrong. I had

Source Analysis paper - Essay Example However, issues on how to implement the rights derived from the laws of nature came out and were scrutinized by those who voiced their concerns with regards to the clauses in the declaration about freedom and equality such as the upper class elite whites, the working-class white males with properties and those without, females, the slaves, and the native Indians who were pushed on the brink of disappearing. The differences in the ideals and beliefs concerning equality among various members of the public generated questionable governance which further erupted during the civil war, of which such problems as contradicting ideas in running the society, economy, and politics stemmed up from the unyielding of some patriarch-minded people to allow each and everyone in the society the same amount of liberty and justice that white males have enjoyed. Before discussing the contradictions that lead to issues on governance as stipulated in the Declaration of Independence, the Laws of Nature comp ared to man-made laws such as those imposed by the British Empire will be elaborated first. Puritan John Locke wrote his ideas on how the Natural Laws were able to shape how mankind thinks through reason, and gives explanation as to why there is a strong need for America to become independent from Britain altogether. One of his strongest arguments is that due to the natural order of things, wherein all people were born equal regardless of status or color, it can be expected that discord will arise from the public once this natural right has been revoked (Fiege 72). The loosening of the British Empire’s hold over the colonies came up as the result of the violation of the natural law, especially since it treats not just the colonists but its entire population as people of lower status, further causing problems in controlling and ruling both the colonies beyond the Atlantic Ocean and the rest of the British population in general (75). The same can be said with regards to the rig ht of property and life, wherein the British Empire’s strong hold on tax collections from the colonies and of stripping private property to become the public’s were overturned due to the natural law which states that anything a person works for and builds into becomes a part of himself, and becomes his own property (72; 77). By virtue of the natural law the colonists do not have any obligation to pay taxes to the British Empire since these are all the product of their toiling in their own lands, in a place far away from the mother country. Lastly, the natural right to live independently and in sovereign was invoked, which was mainly due to the growing differences between how the colonists and the British Empire think and manage society. Due to the violation of the rights of liberty and property through threats from the British army and the tyrannical rule of the monarchs, the colonists defended their stance in separating from the mother country altogether by declaring themselves to have a different way of thinking and living, and must therefore be provide for their own safety and security in the process of changing towards a much more independent society and less of a monarchic one (73). Using the natural laws in explaining basic human needs such as the right for equality, for life, and for

The samples that were taken for the study was dependent on the researcher social network via snowballing sample technique, which has a bias in sample selection. In addition, the participants were aware that they were carrying out research, and since blinding was not possible Hawthorne effect may distort the results. The ethical aspects were considered in the following aspects: An approval letter was obtained from the Institutional Review Board of the University, the nurse explained to the participants the purpose of the study and they gave informed consent. In addition, confidentiality was observed and any participant was able to stop participating in the study unconditionally. In week 1, part one of the data collection was administered for all the groups. For experimental group, part 2 was administered as baseline after five minutes of rest period and before 30 minutes of music intervention. Both non-music and music intervention were carried out in a quiet and restful environment without interruptions. For participants in the music intervention, after 30 minutes music intervention, the research nurse stopped the music and collected participants data immediately. For those in the non-music, after the 30 minutes the research nurse collected their data immediately. This was done for subsequent week 2 to 8. Using RM ANCOVA adjusted by baseline depression scores of demographic characteristic to test for depression between groups yielded significant difference (p=0.016). No significant difference was found between week 2 (p=0.639), week 3 (p=0.213) and week five (0.089. However there was a significant difference between groups at week 4 (0.0005), week 6 (p=0.012, week 7 (p=0.008) and week 8 (p=0.0006. from these results it can be stated that there is a significant music influence on depression. The music group had a considerable

Experiment 6 Lab Report Example | Topics and Well Written Essays - 750 words - 1

Experiment 6 - Lab Report Example The small cost of iron nanoparticles and their ability to reduce toxic contaminants into non-toxic iron hydroxide products make iron nanoparticles application techniques preferential. I addition their installation are simple and require minimal maintenance and react with a diverse range of contaminants. The delivery method of these nanoparticle based applications are also diverse in nature and therefore can be used in dealing with many forms of contaminants either of differing concentrations or chemical and physical characteristics. From previous research, it has been observed that iron nanoparticles cause a significant reduction in the concentration of contaminants. The aim of this experiment is to analyze the change in concentration of indigo carmine dye in its reaction with iron nanoparticles. Dyes are common pollutants though not frequently recognized. From figure 1, the concentration of indigo carmine dye is observed to be relatively constant before the addition of iron nanoparticles. There is little or rather insignificant change in the concentration of indigo carmine dye before nanoparticles are introduced into the solution. From the first analysis, it was determined that the rate of change in concentration of dye in the first 60 seconds can be calculated as 0.00591 M/s. The overall change in concentration is 0.35443M. The second analysis using 0.105nm of iron nanoparticle gave a rate of change in dye concentration of0.0091M/s in the first minute with an overall change in concentration of 0.548M. Figure 2 shows a negative correlation between the changes in concentration of dye with time on addition of iron nanoparticles. The same observation was made in figure 3 where 0.42nm iron nanoparticles were used. From table 1, it is observed that the fastest rate (0.0091) in removal of dye from the solution was obtained with 0. 105 nm of iron nanoparticles. This could be contrary to expectations as 0.04nm iron particles should have
