Banning Progress in the World of Swimming
Restricting Progress in the World of Swimming Picture an adolescent who focused on a game nearly as long as he can remember, went to each training and dry-land instructional course for some continuous years and asked his folks to get him a 600 dollar polyurethane bathing suit just to be to some degree like the scandalous Micheal Phelps, Ryan Lochte, or Jason Lezak. Presently picture a similar child being informed that he can no longer wear that Ãtechnicalâ suit at any swim meets and that he needs to depend on the crude Ãjammersâ bathing suit, which has not been utilized in the Olympics since 2004. This all sounds strange; notwithstanding, it is absurdly true.At the yearly 2009 Convention of USA Swimming Delegates, speaking to clubs from every one of the 50 expresses, a staggering vote had been thrown for early execution of a restriction on innovative bathing suits. Just to follow in not so distant future, that is on Jan first of 2010, will be a similar reaction from the NCAA, FINA, and various secondary school swimming assoc iations, including New Yorks PSAL.English: Ryan Lochte during 2008 Olympic Trials (O...The USA Swimming boycott will produce results on October first, 2009 and will discard the fantasies of incalculable adolescents, hard-earned cash of endless guardians, and make progress toward advancements in the realm of serious swimming all into the bin.If an individual works his heart out both genuinely and intellectually so as to accomplish a specific objective, shouldnt he be given indistinguishable open doors from the individuals who previously accomplished that objective? A run of the mill secondary school youngster who is a piece of a USA swimming club outside of school normally spends and normal of twenty hours in the pool week after week. Finishing exercises that aggregate more than 5 miles day by day, which is more that most people walk, the high schooler who experiences such mental and physical pressure is uncontrovertibly decided toward accomplishing a specific objective.

First Chapter of The Strange Case of Dr Jekyll and Mr Hyde Essay exampl
First Chapter of The Strange Case of Dr Jekyll and Mr Hyde ââ¬ËThe Strange Case of Dr Jekyll and Mr Hydeââ¬â¢ is a novella, short novel, which was distributed in the Victorian period. It has a gothic secret story sort and has a baffling, genuine tone. The general novella is set in London. This exposition will break down how the writer catches the readerââ¬â¢s intrigue what's more, presents the key thoughts in part 1 of ââ¬ËThe Strange Case of Dr Jekyll and Mr Hyde.ââ¬â¢ This exposition will assess how the creator, Robert Louis Stevenson, utilizes diverse language, how RL Stevenson employments symbolism, structure and structure, and the settings to catch the readerââ¬â¢s intrigue. The key thoughts in section 1 of ââ¬ËThe Strange Case of Dr Jekyll and Mr Hydeââ¬â¢ are: duality of human instinct, mammoth in man and notoriety. When ââ¬ËThe Strange Case of Dr Jekyll and Mr Hydeââ¬â¢ was composed it was accepted that individuals had two distinct characters, or otherwise called ones Doppelgã ¤nger. This falls under the segment of duality of human nature. Notoriety was essential to individuals provided that somebody lost it they would think that its difficult to get it back. RL Stevenson was conceived in Edinburgh, Scotland, and had a wiped out youth. He was a lone kid and his folks were trusting large things from him. Stevenson voyaged a great deal in his life and was frequently sick. In 1885 Stevenson composed ââ¬ËThe Strange Case of Dr Jekyll and Mr Hyde,ââ¬â¢ however it wasnââ¬â¢t distributed until January of 1886. This article will initially cover how RL Stevenson caught the readerââ¬â¢s enthusiasm utilizing the abstract gadgets, language, symbolism, structure and structure, and setting.

Essay on Urban Legend of Car Headlights - 1480 Words
Lights Out In preparation for this writing assignment, I interviewed about 15 students at the University to collect their urban legends. One legend, often called ââ¬Å"Lights Out,â⬠was mentioned by just about all of the students I interviewed. Those who did not mention it on their own recognized it when I described it. I interviewed a 19-year-old male sophomore who anticipates getting into the School of Business. He transferred from Community College this past fall, and currently lives with a relative in a nearby off-campus home. He went to a small Catholic high school. He recalls first hearing this legend early in high school, probably between freshman and sophomore year. After telling him the purpose of the interview, I began theâ⬠¦show more contentâ⬠¦Afterward, I asked him if he or anyone he knew had ever tried this before. He said, ââ¬Å"I have (pause)â⬠¦ I didnââ¬â¢t die (pause)â⬠¦ that time (smile).â⬠The way he smiled at the end of his performance re-established his normal disposition and alerted me that his serious tone earlier was just part of the act. His overall performance of the legend was similar to that of other students that I interviewed. When telling stories they seemed serious, but by the end their concern was clearly part of the performance. Many students I interviewed told me relatively the same story, and one female student even mentioned receiving an e-mail about it years ago. Unlike other urban legends I have heard, this story did not really change significantly from person to person, perhaps because it is so straightforward. Barbara Mikkelson provided many examples of this warning story, which is usually spread by e-mail or fax. One such example describes the murders as taking place on a certain weekend: ââ¬Å"Gang Initiation Weekend. ( Please Read Very Important!!!)

Leadership Styles And Theories Of Leadership Essay
Generally, leadership is the art or process of influencing followers and subordinates to achieve the organizational goals. It helps an individuals or a group to identify its goals and assists in achieving the stated goals. Because of importance of leadership all kinds of group action, there are considerable number of researches and theories on leadership and many kinds of leadership styles like Greatman theory, power influence, Trait approach, Behavioral, Situational or Contingency approaches; Below, the Early Behavior Theory of leadership is being described. ï⠧ Behavioral Theories of Leadership: The limitations of trait theory led to significant change in the leadership Approach.

A Review of Laser Processes Used in Solar Cell Fabrication Free Essays
A Review of Laser Processes Used in Solar Cell Fabrication Abstract There are many different laser techniques that can be used in the production of solar cells. By examining the research which the various solar cells were fabricated with laser technique, it is possible to understand the pros and cons of using laser for produce the cells. The following paragraphs will list which process the laser technique have been used in this review. We will write a custom essay sample on A Review of Laser Processes Used in Solar Cell Fabrication or any similar topic only for you Order Now Introduction The buried contact solar cell was invented at University of New South Wales by Green et al. in 1983. These solar cells have a relatively high efficiency approximately 25% and present a possibility of cost-reduction with applying this technology to the manufacturersââ¬â¢ production lines. The following are the general main steps of forming the buried contact solar cell: 1. Texturing of surfaces 2. Top surface diffusion 3. Oxide growth 4. Groove cutting and diffusion 5. Aluminum deposition and sinter 6. Metal plating 7. Edge isolation The key parts of this process, which result in the cells become more efficiency than the standard screen printing solar cells are the laser grooving and groove diffusion to reduce the cell shading and contact resistance and the texturing which reduce the surface reflection. A schematic of a buried contact solar cell is shown in the figure below (Green 1995). [pic]Figure 1: Cross-section of buried contact solar cell Research continues working on the ways which could further improve the efficiency of the buried contact solar cell. With the statistics obtained from the experiment, they can try to figure out the effects which using different methods and materials in solar cells would cause. These parts include different diffusion profiles to form the p-n junction, surface passivation using different materials, and the different methods of grooving of the silicon, rear surface treatment, metallization and so on. Laser texturing In order to reduce the reflection effect of the solar cells, front surface texturing is one solution. There have many methods to increase the light trapping, such as mechanical scribing and reactive ion etching. However, laser texturing could effectively texture the multicrystalline surface, providing isotropic etching that other techniques cannot do. Abbott and Cotter (2006) revealed that with deeper laser texturing, the less the front surface reflection is. More detailed results are shown in figure 2 (adapted from Abbott and Cotter 2006). Note that with very shallow texturing (10mm), they cannot trapping very well, as a result behaving like the planar one. Figure 2: Front surface reflection of laser textured samples with different ablation pit depths (0) 10mm, (? 20mm, (? ) 30 mm, (*) 40 mm, (x) 50mm with residual slag, (+) planar silicon and (line) random pyramid textured silicon. It is straightforward that we should texturing deeper pit, however, this will increase the surface recombination rate, which is detrimental to solar cells. Even though the pit depths 50mm have the lowest reflection, it will leave some slag in the pits that acting like defects. These residual slags will enhance t he surface recombination rate, reducing the open-circuit voltage as well as the efficiency of the solar cells. Finding better parameters of operation to texture the wafer properly without the appearance of slag is therefore becomes the main issue for the manufacturers. Top Surface diffusion The conventional method for doping materials is the thermal diffusion which performed at high temperature (over 800? ). The process is so-called solid state diffusion and has various methods, for instance physical vapour deposition, to control the doping profiles. Also there is a considerable alternative method of forming doping areas in silicon solar cells by using laser-doping. With the Nd:YAG pulsed laser, the doping profiles can be controlled with the desirable doping area. Ogane et al. (2009) asserted that by using the laser doping technique with 0. 5W output, it can fabricate the solar cells with comparable efficiency to those fabricated by thermal diffusion methods. Some statistics of the result from their research are shown in figure 3 (adapted from Ogane et al. 2009). Note that a large number of the oxygen atoms are induced to the solar cells owing to the operation is in air. This increase the sheet resistance and as a result, reducing the efficiency of the solar cells. The advantages of the laser doping process are that it can be operated at room temperature, in the atmosphere, as well as the easier process forming a selective doping area without any lithography pre-set processes. With these advantages, even though the properties of these solar cells are slightly worse than the cells handled by thermal diffusion, it is acceptable to some manufacturers and worthy to work on it. [pic] Figure 3: The average of six solar cells properties of cells with emitters fabricated by laser doping as a function of laser output power, compared with the case of thermal diffusion (TD). Laser groove The most common device which is used to form the laser grooved front surface contacts is the Nd:YAG pulsed laser, operating at a high frequency. The depth of the laser groove after lasing is typically 30 microns deep and approximately 20 microns wide. During the process, laser will vaporises silicon through the oxidation layer, and this will induced the thermally damaged to silicon. Such this damage will acts as recombination sites of carriers when operating the solar cells, minimised this defect is therefore necessary in order to improve the efficiency of the solar cells. Studies on this part (Schoonderbeek et al. 2007) have revealed that using the shorter wavelength of the laser, i. e. the higher power output can reduce the thermal damage induce by the laser. [pic] Figure 4: Increased lifetime ratios (decreased laser damage) are obtained when scribing lines using short-wavelength lasers. Figure 4 (adapted from Schoonderbeek et al. 2007) above shows that by using lasers with short-wavelength at either 532nm (green) or 355nm (UV) will have better properties in comparison to 1064nm (IR) laser. Nevertheless, the lower cost of the IR laser is more favourable to the manufacturer. Thus the solar cell research of this part is undertaken at institutions and companies in order to find out the better trade-off point. Back surface field and laser-fired contacts The technology which usually used for rear contact passivation in solar cells is that highly doped region near the back contact. This is called back surface field. Normally aluminium is applied to it by evaporation, following by sintering to make aluminium atoms diffuse into the silicon. For reducing the cost per watts generated by solar cell, some different methods were tested for the feasibility analysis. One of the ways for reducing the cost is doping aluminium locally (Meemongkolkiat et al. 2006). It is obviously that doping less metal could reduce the cost, however the efficiency should not be diminish too much. In this process the oxide on the back surface is partially etched prior to aluminium were screen-printed on it. In their research, with choosing the aluminium screen-printing pastes properly (the composition is not provided in their paper), the efficiency of the solar cells are adequately (16%) compared to the normally full back surface field (16. %). Alternatively, aluminium deposition can be applied to the solar cell with the passivated emitter and rear contact, followed by fast scanning laser firing to reduce the rear surface recombination rate as well as improve light trapping. With this so-called laser-fired contact technique, Schneiderlochner et al. (2002, p. 32) demonstrated that the efficiency of the laser-fired contact solar cell can reach up to 21. 3%. Some result s from their research can be seen in figure 5, which are adapted from Schneiderlochner et al. 002. Note that the silicon nitride passivated layer has a lower efficiency maybe due to degradation in passivation quality during laser firing. [pic] Figure 5: The solar cell results with the laser-fired contact technique compared with conventionally processed passivated emitter and rear cells The main advantage of the laser-fired contact is that after possessed a passivating layer and depositing the aluminium, there is only one step needed (laser firing) instead of several processes of photolithography. Hence by using Nd:YAG pulsed laser system for laser-fired contact processing, the cost per watts can be reduced due to less handling steps, as well as the expensive chemicals. Summary There are some different techniques with respect to laser that applied to the fabrication of the solar cells are discussed above. With the laser system applied to the back surface field and laser-fired contacts, the cost can be reduced by using less costly chemicals, whereas shrinking the cost of instruments and operation for the case that laser system induced to the top surface diffusion. The aims of both grooving and texturing using laser technique are improving the properties of the solar cells. The laser system provides the possibilities of reducing the cost per watts without decreasing too many characteristics of the solar cells, which is the most important issue for manufacturers. Therefore, studies focus on these techniques will continue while some of them are already used in fabricating solar cells with other techniques. The ultimate aim of these is make the solar cells as cheap as possible so that public are willing to having it, thus minimizing the environment impact.

Depreciation Practice and Public Policymaking
Question: Discuss about the Depreciation Practice and Public Policymaking. Answer: Introduction: Auditing is a process where the auditors of a business take some samples of the financial documents of the business; and then test and verify them so that all the material misstatements can be identified, if any. After that, the auditors give their independent opinion about the audit result of that particular business. This whole process is called the planning and execution of audit program (Glover, Prawitt and Messier 2014). One of the main aspects of the audit program is to find the audit issues that give the necessary direction to the auditors. The auditors need to find out the hidden audit issues from the audit situation; and then, they need to mention it in the audit documents. Hence, it can be said that it is the utmost responsibility of the auditors to find out the audit issues so that they can be documented in the audit files and necessary actions can be taken. The given case study states that City Limited is one of the major property developers Australia. However, the main operation of the company is based in Brisbane. It is mentioned in the case study that an economic downturn is going on the central business district of business in the property development sector. Another reason that is supplying fuel in this economic downturn is the abundance of city office spaces. In this particular case, there is a lot of responsibility of the auditors and the first responsibility of the auditors is to identify the audit issues in the whole situation. Hence, in this regard, the responsibility or the job of the auditors is to conduct a detailed analysis on the total situation and find out the audit issues of the situation. There can be various reasons that lead to the downturn in the property development sector. Some of the reasons can be the high rate of unemployment; the high rate of interest in the home loans; a severe recession period in the econom y of the country; the halt in the rise in the population of the country; slowdown in the foreign investment; the change in the rules and regulations by the government and many others. In this case, the auditors need to find out which of the above reasons are the potential audit issues in the given situation (Seawright 2013). There are various kinds of reasons for which a business or organization considers to buy a new computer set or a new software. One of the basic reasons for the buying of a new computer is to smooth the various business operations of the organization. The given case study says that Web Limited has bought a new computer system for the organization. The company has bought the new system for two reason; they are to make the financial analysis of the company more effective and to improve the quality of management reporting. In this situation, some audit issues need to be identified by the auditor of the organization. The first aspect that the auditors need to consider is to verify the capability of the new computer system. This can be tested by running the new system so that it can be seen the system is assisting in the financial analysis and management reporting. Apart from this, there are various other audit issues that the auditors need to maintain. They are to manage the policies for the new system; to manage the access of the users; to manage the various kinds of security issues relating to the new system; to configure the networks and many others (Holm and Zaman 2012). These audit issues need to be considered by the auditors of Web Limited. Many crucial issues need to be considered at the time of opening a new overseas sales outlet. The provided case study states that Beauty Private Limited has established a new overseas sales outlet. The basic audit issue in this regard is to analyze and evaluate the possibility of profitability of the new outlet. On the other hand, it needs to be made sure that the transfer of the inventories will reduce the lead-time of the business. Reducing the lead-time is an important aspect as it helps to make the business more effective towards their customers. The auditors of the company should analyze that the strategy of free distribution of samples. This strategy needs to be perfect for the success of the business (Prawitt, Sharp, and Wood 2012). The auditors of Beauty Private Limited need consider these audit issues. Audit approach refers to a risk analysis methodology that analyzes the effects of envi0ronment in which they are operating. This is a part of the internal control of an organization. There are two types of audit approach. They are Test of Control Approach and Substantive Approach. Both these approaches cannot be used in the same condition. The nature of the situation demands the choice of the audit approach. These situations are discussed below: Test of Control Approach: Test of control approach is used to analyze the effectiveness of the business control that is used by the client for the prevention and detection of material misstatement in the financial reports of the company. The test of audit approach assists the auditors to decide whether to depend on the test system of control of the client or not. In case the auditors find that the system of control of the client is not effective and weak, then the auditor decides to adopt substantive audit approach that increase the cost of the whole audit program (Johnstone, Gramling and Rittenberg 2013). In the process of test of control approach, the auditors perform two three kinds of operations. They are re-performance, observation and inspection. The auditor does re-performance operation in order to identify the control used by the audit client and their effectiveness. In order to observe the control elements of a business process, the auditors use observation approach. In the inspection stage, the auditors use to test different kinds of documents to verify signatures, stamps and others. Substantive Approach: The auditors adopt substantive audit approach at the time of weak internal control system of the audit client. In substantive approach, the auditors use to test and verify all the business documents of the audited client without depending on the information provided by the management of the organization. The auditors place zero reliance on the control system and information of the audit client (Knechel 2016). In this case, the auditors have to organize a detailed analysis of the various business documents of the organization. This is the situation where substantive audit approach is applied. There are three kinds of risk in auditing. They are inherent risk, control risk and detection risk. Inherent risk is the kind of material misstatement that arises due to errors and omissions. There is not any part of internal control in this kind of risks. Control is the kind of risk that arises due to the lack of control system of the audit entity. Here is not any part of omissions or fraud in it. Detection risk is the kind of risk that arises due to the failure of the auditor to detect the material misstatement in the financial documents (Knight 2012). Based on the above discussion, it can be said that substantive approach is applicable for the inherent risks as this risk arises due to omission and fraud. Test of control approach is applicable for control risk as these kinds of risks arise due to the weakness in the internal control system of the audit client. Lastly, substantive approach will be applicable in case of detection risk, as the auditors need to examine more samples to detect the material misstatement in the financial documents of the organization. Maintaining various aspects of depreciation is lying on the hands of the audit client as depreciation is totally the matter of inter control system of the company. It is the responsibility of the management to set up the depreciation method and the percentage of depreciation. Hence, it can be said that the auditors will use the test of control approach for the accuracy and completeness of depreciation, as the auditors need to test the internal control system of the audit client. However, the auditors can use substantive approach if they think that the internal control system of the client firm is not effective and there is a strong need to adopt the substantive audit approach. It can be happened that there is some kinds of omission or fraud in the value of depreciation at the end of the year. To avoid these kinds of situation, the auditors sometimes use the substantive approach of auditing at the time of making the balance sheet (Drew and Dollery 2015). As discussed earlier, auditing is an important aspect for every business organization. The process of auditing helps to establish clarity in different financial and accounting operations of an organization. On the other hand, one cannot deny the importance of the communication of accounting information in an organization. Accounts is a critical process which helps to keep records of all financial transactions of an organization; it helps to verify the source of every income and expenses of the organization which is essential to the auditors of the organizations. The effective communication of accounting information indicates that the auditors and other relevant persons of the organization have the proper access of all the necessary accounting information. At the various stages of auditing, the auditors need different kinds of accounting information; and for this purpose, the proper communication of accounting information is a must need. There are numerous benefits of the effective co mmunication of accounting information in an organization (Hall 2012). The first benefit is reliability. Different kinds of accounting data and information provide reliability in the audit process as it gives the auditors the necessary direction to continue their jobs. Based on the communicated accounting information, the auditors can detect the material misstatement in the financial and accounting documents of the organization. On the other hand, based on this information, the auditors can judge that whether the material misstatement is due to the lack of internal control of the audit firm or due to any kind of fraud or omission. The second benefit is analytical tool. The communicated accounting information can be used as an effective analytical tool to understand the financial position of the company. The auditors are sometimes instructed to comment on the financial position of the audited firm. In that kind of situation, the auditors have to analyze the business information of the organization that is provided by the accounting communication system. Based on the analysis of the information, the auditors comment on the financial situation of the audit client. The third benefit is that the effective communication of accounting information passively helps the organization too gain the trust of the investors. The investors take the investment decision based on the declaration of the auditors report in the ann ual report of the organization. In the presence of all necessary accounting information, the annual report of the organization reflects the true financial image of the business organization and helps to attract the attention of the investors (Lobo and Zhao 2013). These are the three major benefits of the effective communication of accounting information to the auditors. The companies can implement proper communication of accounting information by some specific ways. One of the ways is the implementation of accounting information system in the organization. The role of accounting information systems is to gather, process, deliver and store all the accounting information in an organization for various parties. It is desired in every organization that the auditors will get all the necessary information from the management to carry on the audit process. Hence, from the above discussion, it is clear that success of the audit process in an organization vastly depends on the delivery of accounting information of that organization. This discussion is a clear evidence of the fact that there is a connection between auditing and the communication of accounting information. References Drew, J. and Dollery, B., 2015.
