Wireless devices without Wi-Fi Essay Example for Free
Wireless devices without Wi-Fi Essay 3.1.1 What would happen if wireless devices were not governed by the Wi-Fi Alliance and each vendor had its own standards and protocols? What impact would this have on your personal life or business communications? Personal information and business will slow down due to each vendor having its own standards/protocols. It will also be more vulnerable to attacks and make accessing more difficult. 3.1.2 Give another example of a model that is used to visualize something that is difficult to observe or perceive. How does the model make it easier to understand? Another way of displaying information for easier understanding is to use a flow chart. A flow chart can be used as a step by step guide. 3.1.3 Based on what you already know about networks, what are the different layers you think would be necessary for communication to be mapped to a model? Consider direct connections between host devices and connections that require other routing equipment, such as a hub, switch, or router. 1. Data link 2. Physical 3. Application 4. Network 5. Transport 3.1.4 The granularity of the reference model will often determine the usefulness of the model. What will happen if a model is too general? What will happen if a model is too granular (focused on individual detail)? If the data is too detailed, it may overlap with other information. However if the data is too general, then there may be crucial information missing. 3.1 Review 1. Why would a three-layer model of communication that has the layersà physical, network, and application be insufficient to adequately describe network communication? The model would be insufficient because it would not have the ability to transport data to any other network. 2. What is the history of the OSI reference model? How did it come about and why was it created? Use your textbook and internet research to support your answer. OSI was created in the late 1970s. It was created to define a unifying standard of architecture for networking systems. OSI was meant to be the foundation for what would later be known as the internet but when comparing to TCP/IP protocols, OSI just wasnââ¬â¢t enough to support the rapid growth of the internet. Now, the OSI model is used to explain networking in general terms. OSI is still used today by software/hardware designers to clarify roles in a networking system. 3. What is the history of TCP/IP model? Why was it created? Use your textbook and internet research to support your answer. TCP/IP was developed in the early 1970s, originally as part of a research network the United States Defense Advanced Research Projects Agency (ARPA) developed. However, due to the TCP/IP protocols limitations and flaws, ARPA developed a new network. In the mid-1970s, it was found that TCP was attempting to do too much. This is when they decided to split TCP and IP into two separate layers. In the 1980s, TCP/IP was used to run ARPAnet and also started to expand to other machines and networks, completely evolving ARPAnet. This is how the internet was born. 3.2.1 Using Figure 3-1, define each layer of the OSI model in your own words and state what each layer provides. Use your textbook or internet research to support your answer. Application ââ¬â Quality of service is established, communication partners are identifies, user authentication and privacy is considered and established. Presentation ââ¬â Changes data into a form that the application can accept. Session ââ¬â Manages and terminates connections between applications. Transport ââ¬â Transfers data between systems, maintains flow control and recovery. Network ââ¬â Provides switches and routing technologies and creating logical paths. Data link ââ¬â Data packet is encoded Physical ââ¬â provides the hardware necessary for sending and receiving data, bit stream 3.2.2 Using Figure 3-2 as a basis, complete the diagram to show the intermediateà encapsulation provided by each layer. Use your textbook and internet research to support your answer. Transport ââ¬â Segments Network ââ¬â Packets Data link ââ¬â Frame 3.2.3 Briefly explain the de-encapsulation steps in the communication of host B receiving a message and host A destined for an active application. Host A will use application for the OS while allowing the PC to still communicate to other devices. Transport will control the data sent and received. The network will place IP addresses to the packets allowing data to be added to the MAC addresses and physical link between host and lines. Exercise 3.2.4 Explain why routing devices do not need the upper layer of the OSI model to route traffic. What is the highest layer of the OSI model used by the router to decide where to forward traffic? The first three layers of the OSI is typically what a router needs to route traffic. The first three layer are physical, data link and network. The highest level the OSI decide where to forward traffic to is the transport layer which is located in the host layers. Lab 3.2 Review 1. How does the abstraction of the physical layer facilitate interoperability across networks using different types of physical wires? IP terminals might be located in different parts of the build making it complex. There are lines coming in and out of the build that might be different than that issued to a company. To try and replace one will be complex, confusing and time consuming if unsure. 2. The OSI model is not directly implemented in networking and often the distinction between the layers will blur in implementation. Why does it endure despite these issues? Use your textbook and internet research to justify your answer. Technicians still use the OSI model because it gives a step by step guide onà how the information is being transported and makes troubleshooting more precise. 3. Given the purpose of each, is it necessary to retain the top three layers of the OSI model as separate entities? Use your textbook and internet research to justify your answer. It is not necessary to keep the top three layers of the OSI model when TCP/IP combines the top three layers of OSI into one layer that ultimately does the same functions. Exercise 3.3.1 Using your textbook and internet research, create a mapping between the TCP/IP model and the OSI reference model. What are the distinct differences between them? One major difference between OSI and TCP/IP is the first three layers of OSI are combined into a single layer in TCP/IP known as the Application Layer. The other difference is the last two layers, Data link and Physical layer are combined into one layer known as Network Access or Link Layer. Exercise 3.3.2 Identify the layer in which each protocol resides according to the TCP/IP model. OSI # OSI Layer Name TCP/IP # TCP/IP Layer Name Encapsulation Units TCP/IP Protocols 7 Application 4 Application Data FTP, HTTP, POP3, IMAP, telnet, SMTP, DNS, TFTP 6 Presentation 5 Session 4 Transport 3 Transport Segments TCP, UDP 3 Network 2 Internet Packets IP 2 Data Link 1 Network Access Frames 1 Physical Bits Exercise 3.3.3 The most common protocols used from this suite are IP, TCP, and UDP. Briefly describe the purpose and function of each of these. Use your textbook and internet research to support your answer. UDP ââ¬â User datagram protocol ââ¬â this is a connectionless service the gives best-effort delivery but does not guarantee delivery. This is often used for point-to-point and point-to-multipoint communications such as video conference applications. IP ââ¬â Internet protocol ââ¬â Primarily a communications protocol within the internet protocol suite that relays datagrams across network boundaries. Ultimately it establishes the Internet. Delivers packets from the source host to destination hosts based on IP address in the packet header. TCP ââ¬â Transmission Control Protocol ââ¬â Core protocol of IP. Known for its reliability and error checking delivery between programs running on computers connected by common networks. Sends data in the form of message units between comp uters using the internet. Lab 3.3 Review 1. UDP is a connectionless protocol, unlike TCP, so there is no feedback on whether a packet was received. When would this type of protocol be used and what is the benefit of using it? Use your textbook and internet research to draw your conclusions. UDP is ideal for when you are managing a large amount of information and you donââ¬â¢t want to use TCP because the operating system wonââ¬â¢t be able to support that many sessions at one time. This does not happen frequently as TCP has become more reliable but it still is one example of why youââ¬â¢d rather use UDP. UDP can also get a quick response from another server more quickly. However UDP has been viewed as unreliable because there is no feedback and information can get lost. 2. HTTP is the common protocol used to retrieve web resources in a web browser. This runs over TCP/IP networks using TCP. What characteristics of TCP make its use in this situation desirable? Use your textbook and internetà research to draw your conclusion. The feedback feature in TCP is ideal because you are guaranteed that messages will be sent and received successfully. One common application that is a prime example of TCP and its success is through e-mail. Exercise 3.4.1 The data link layer introduces physical addressing in the form of Media Access Control (MAC) addresses. Each frame header is Ethernet, for example, will contain a source and destination MAC address. Why is this sufficient to route traffic locally without invoking the higher-level logical addressing? Use your textbook and internet research to guide your conclusion. MAC addresses are sufficient enough to route traffic to other networks because the frame header of MAC addresses contains all that is required without having to access higher level logical addresses. Exercise 3.4.2 Choose one of the captured packets. Click the + sign next to the Ethernet entry. This should give you the data link layer information for the frame, including the source and destination MAC addresses. Record the frame number and the source and destination MAC addresses identified by the data link layer heading. You can identify a MAC address by its format; for example, 00: 26: 62: 65: 81: 07 00:26:62:65:81:07 is a MAC address. These are commonly written in hexadecimal shorthand. Exercise 3.4.3 Open a web browser and navigate to a site that you use frequently (or visit www.pearson.com) while the packet capture is active. This will record the individual frames involved in resolving the website and delivering its content to your PC. When you view this traffic in the life packet capture, what protocols do you see invoked? You can find these under the Protocol heading for each frame. Exercise 3.4.4 and Exercise 3.4.5 cannot do because student doesnââ¬â¢t have access to data link layer connection (Omnipeek). Lab 3.4 Review 1. Wireshark give you the ability to save captured traffic. This can be aà great benefit to network administrators, but it can also pose a security risk. What kind of security risks does this present? Use your textbook and internet research to support your conclusion. There are a few risks associated with Wireshark. There is a possibility of a back-door hack, and the security configuration of Wireshark enables it to run in the background after exiting. While running in the background, one can access your routing information, IP addresses, passwords and usernames. 2. The frame encapsulates all other information from the higher layers of the network communication. What kind of information on the network layer encapsulation is available in Wireshark? Using Wireshark, you can track Wi-Fi access, IP addresses, network routings and encrypted packets.

About 71.1 % adult of the population are considered to be obese (CIA 2014). Due to the WHO (2014), obesity is defined as ââ¬Å"abnormal or excessive fat accumulation that may impair healthâ⬠. The most important direct results or epiphenomena are cardiovascular diseases (e.g. stroke), which are mentioned by the WHO as the leading cause of death in 2012. Other ailments are diabetes, musculoskeletal disorders (e.g. osteoarthritis) some sort of cancer as well as mental disorders (WHO 2014). Nowadays, obesity at Nauru may result from the lack of access to a healthy environment, especially lack of access to fresh and healthy food and lack of physical activity. Besides that, other reasons from previous periods have to be discussed shortly, which may also be responsible for the present situation. After independence in 1968, Nauru used to be one of the richest countries in the world with high rates of GDP per capita due to its rich phosphate deposits. Due to bad governance, for instance the mismanagement of funds, lack of structural, economic and environmental policies, Nauru went bankrupt finally. Today, the republic is a low-income country and can be characterized by the following attributes: Lack of established industries Deteriorating capital plants High unemployment rate of 90% due to estimations by the CIA of 2005 (CIA 2014) Destroyed landscape (90% of the land are deteriorated due to intensive phosphate mining) (CIA 2014) High dependency on imports of almost all goods (food and other consumer goods) High dependency from aid, especially from the donor Australia In spite of all these health problems, Nauru lacks a good health care system and it cannot afford to create one because of its weak economic and social state. Now, Nauru lacks the capacities to deal with the most important health risk obesity on the one hand, which affects the majority of the country. On the other hand it can be estimated, that Nauru will not be able to create an environment for the community to prevent further progress of overweight and obesity within the next years. For that reason it can be stated, that the country will not be able to deal with the problem in a proper way in the short and in the intermediate term. In the light of this, the paper would examine the present situations of Nauru healthcare and why the standard financing options wonà ´t work while also falsifying already tested hypotheses about the effectiveness of standard financing options. 2 Possibilities and constraints of health protection policies in Nauru 2.1 Assessment of the requirements of adequate health policies in Nauru What are the requirements for an adequate health policy, and how might the situation in Nauru look like, in detail? In the following, this chapter is going to answer the stated questions. Therefore, it uses six basic indicators of good health policies; the focus on lifestyle and needs of population, consideration of other sectors relevant for health, participation of the population, use of locally available resources, integration and coordination of preventive, promotional, curative and rehabilitative measures, and decentralization of services. With this, the subject of the following chapter is to create an understanding of Nauruà ´s situation today, while simultaneously trying to present the major problems. Focus on lifestyle and needs of population Beginning with lifestyle, we address directly one of the major problems. Before the country became rich, due to phosphate exportation, the population provided themselves through farming, fishing and hunting (20min 2011). The natural food and the gently cooking preparation, through boiling, supported the inhabitants with healthy, organic and substantial food. But with the growing income the eating habits changed towards imported, fat and durable food from the West, especially, meat and chips found their way in the supermarkets and so into stomachs of the population. Together with a low amount of working people, Nauruan grew fatter and unhealthier. Another problem is that only processed or canned food finds its way on the island, until today, because the transportation of vegetables or fruits would take too long and would be too expensive. Even with an active government, the imported goods are still a problem (20min 2011). The lifestyle of the population changed over the last decades. Todayà ´s government focuses on the problem and is trying to support the population. Information on measures and programs are discussed in several media but are not published via official channels. Therefore it remains questionable, if the governmentà ´s efforts are sufficient and suitable to address the problems. Use of locally available resources ââ¬â considering their scarcity The considerations of the government lead to daily walks of the president, anti-obesity campaigns, with signs and banners, and a support campaign for natural and healthy foods, which seemed to have some success. Especially the small trend towards more healthy food, developed with the growing poverty. Imported food is often more expensive than rural food. Therefore, the people do not have much of a choice and it is hardly to count as a success. Participation of the population in search for solutions The participation of the population seems rather small. Even though the average lifespan of a male Nauruan dropped under the age of 50, the support of the population is limited (WHO Nauru 2012). A few people profit from the working benefits, only the youngest go to school or college. The problem, the 95% obese people, are whether neither young nor working. Most of them are out of school and not working. Therefore, they do not see the necessity for change (Nauru Government 2014). Due to this, they are hard to motivate and engage. Participation of the population is critical for the success of all measures to reduce the health risks. It can be stated, that participation is rather low. It should be a major concern of the government to focus on that issue. Consideration of other sectors relevant for health With the acceptance and notion of the problem obesity, the government tried to support the population through single activities; additional focus on sport activities in the education system, free aerobic classes, the creation of sport tournaments, the provision of more sport areas and the support of those areas with the needed equipment and a guaranteed time for employees to do fitness. Naturally, because only a few people work, only a few benefit from the walking regulation, which does not support a change efficiently. Additionally, they started an anti-diabetes campaign and inform children in schools about the difficulties coming from an unhealthy lifestyle early on. As a result of this, the president walks every day, visible for everyone, on the landing zone of the airport, to motivate the population (20min 2011). Integration and coordination of preventive, promotional, curative and rehabilitative measures The government of Nauru agreed that they could only support the older population through high medicine standards, sufficient medication in case of diabetes, free athletic classes, obesity warnings and specialized medicine treatments (20min 2011). The young generation gets additional education about unhealthy living styles, is supported with more opportunities and motivation to do sports and. The focus of the government therefore lays on trying to change the development of the future generations and alleviation of the present problems for the older generations. Extravagant measures, like the daily walk of the president are one of the things, which were implemented to raise awareness. Decentralization of services The decentralization is not relevant because of the very small size of the country. 2.2 Discussion of Financing Options of Social Health Protection in the Case of Nauru There are various ways that a social health insurance could be financed. This section of the paper will be explaining the various financing options, the various features of each of the options, how they work and then assess its feasibility in financing social health insurance policies in Nauru. The various financing options the paper would examine are as follows: User fees, Prepayment scheme, Government budget and Private insurance. Besides that Social insurance and Micro-insurance are further options of financing, which will not be focused in the following discussion. User Fees This involves an ââ¬Å"out-of-pocketâ⬠financing of health services. In other words, the people would have to pay out of their pocket and it is usually on an immediate basis. It has been argued overtime whether this form of financing is effective or not, and also whether it promotes the use of social health insurance. While some argued that it provides a measure to check over utilization of health services, some argued that it doesnââ¬â¢t encourage the poor (who are the most vulnerable to health risks) to use health services as it is usually too expensive for them to manage. Also, it doesnââ¬â¢t really protect people from risks as there is no insurance element. With all the above mentioned, it is quite clear why this form of financing cannot be used in Nauru. In a country with 90% unemployment according to CIA fact book and with its citizens having no source of income, it will be impossible for them to pay for health services out of their pockets much less immediately. Prepayment Scheme Prepayment scheme as the name implies is the payment for a service in advance. This involves a payment of premium before the occurrence of the hazard. It has same features like the user fees except that it has an insurance element in that the users pay ahead of the occurrence of the hazard. This also cannot work for the citizens of Nauru as most of them are unemployed so there is no way of making payments in installments. Also, most of the employed are working in the informal sector, which makes it even more difficult for pooling of funds. Government Budget (Taxes) The government can also get to finance health care policies. This is usually done by allocating a percentage of government budget to the health care sector. Also, it could be done through payment of tax by citizens to government but usually with subsidies. This form of financing acts as a balance between the rich getting health coverage and the poor getting coverage as well. This is so because it is cheaper, provides universal access with low administration costs and most importantly, more coverage at little or no costs. The Nauru government has an annual budget of $AUD 35.6 million as reported by the UNICEF in 2002, as well as a total expenditure of $AUD 79 million, which brings its deficit to $AUD 49 million. With this huge deficit and 90% of her revenue coming from aid, the health sector remains under funded still even though a higher percentage of her budget goes to providing health services. Making it also almost impossible to singlehandedly provide good health services based on government funding. Private Insurance Private health insurance is a form of voluntary insurance taken out by users themselves for various reasons. It has been argued that private health insurance helps cater to needs of the rich which allows the government to focus on catering better to the needs of the poor with limited resources. Also, it helps to provide more choices to the consumers and acts as a catalyst to reforms and efficiency in public health insurance. Despite all of these advantages, it is still really expensive and even widens gap between the rich and poor. Moreover, it is a bit difficult to administrate. Presently, there is no form of private health insurance in Nauru. This is no surprise as private health insurers usually invest where the profits are higher and also insure people with lowest vulnerability to risks. In Nauru, most of its people suffer from obesity and diabetes; thus, if there were to be any coverage by insurance, these two diseases have to be a main focus but private insurers wonââ¬â¢t want to insure them as the probability of the risk occurring is really high. 3 Conclusions and Recommendation The paper focused mainly on two pillars, which are assessment of the requirements of adequate health policies and financing options. Within the chapters 2.1 and 2.2., we could give evidence for a number of problems, of which inhabitants of Nauru suffers today. Those can be summarized by the following characteristics: 1. Country specific obstacles like the small size, small number of inhabitants, high number of unemployed people, as well as the high number of diseased people and mismanagement in the past. 2. Lack of self-responsibility 3. High dependency burdens 4. Budget constraints These problems affect the health conditions of the country to large extend and worsen the situation of people who suffer from obesity but also support a large number of obesity incidence. We must come to the conclusion that for the same reasons / problems, Nauru will not be able to deal with the problem in a proper way in the short and in the intermediate term. Also, it can be estimated, that Nauru will not be able to formulate adequate policies and strategies to address the needs of those people who already suffer from obesity as well as those who are in danger to come down with obesity. Furthermore it is critical to find sufficient and sustainable sources how to finance the budget and especially a budget for health policies. Even if the authorities are aware of the problem and have been implementing single strategies to fight against obesity, it lacks of a broad and sustainable implementation of concrete measures to address the problem. Due to the requirements of adequate health policies, it can be stated, that Nauru is not able to improve the situation remarkably. At the moment, the awareness concerning a responsibility and especially self-responsibility of the Nauruan authorities to address the needs of a healthy population is not obvious. The major argument here is, that there is no transparency because of lack of adequate information. In terms of financing options, Nauru has to look for other, maybe unconventional financing options e.g. selling the right for an arts project (film, book) because of the countries unique past or Nauru could initiate a crowd funding campaign, which offers adventure vacation for money. Besides that, Nauru should focus on financing options, which makes the country independent from single donor states like Australia, e.g. credit at the World Bank.

Currency Risk Management in Indian Banks
Currency Risk Management in Indian Banks EXECUTIVE SUMMARY The objective of the project is to study the attitude of Indian corporates towards currency risk management and the problems faced by the companies dealing with their currency exposure which occur as a result of exports or imports or both. The study has also included the problems faced by the banks, the authorised dealers of foreign exchange in India, in managing their forex (foreign exchange) market operation as it has large implication on the corporate currency exposure. Indian corporates have an attitude of staying away from the currency market. Companies consider hedging as unwanted cost centres. Periods of exchange rate stability bred complacency. Importers are confident that the Central banks shall intervene to halt any rupee decline where a exporters are of the view that rupee has always been over rated and that there is no way that it shall appreciate from the present value. These reason keep them away from hedging their exposures. Companies which are involved in hedging, go the conservative and orthodox way to hedge their exposure. Not a single company surveyed, take financial derivatives other than forward contracts as tool for hedging their exposure. This is mainly because of lack of awareness and experience. Many of the companies feel that the importance of currency risk management will increase, in coming years but very few of them are making themselves ready to face the situation. Banks that act as facilitators are also suffering from acute problems. Public sector banks, which control 75% of Indian forex market, have always been under staffed and governed by bureaucratic rules. The market for derivatives other than forward contracts is very shallow. Many of the banks reason it out to be as a result of corporate reluctance and lack of information and technology. Most of the banks in public sector do not merge the forex and money operation and they do not treat their forex operation as a separate profit centre. This bred inefficiency in their working which has affected the corporate sector. The corporates have been recommended to look strategically into their exposure and take prudent decision in hedging. This decision should be backed by professional treasurers, an efficient back office and good forecasting techniques. They have been asked to go in for various other derivatives that are flexible and cost effective. The banking sector has been recommended to recruit specialised personnel for the job with latest technology to deal in the market. They should start providing variety of other derivatives to the industry. They should also merge their money market and forex operation and treat is as a separate profit centre. These all measures will definitely make the forex market deep and vibrant, which will make the work easier for corporates in dealing with the currency exposure. 1. INTRODUCTION ââ¬Å"We have to sleep with one eye openâ⬠Managing director of an Indian company with investments in Indonesia. This was in reference to the Indonesian rupiah crash which followed the nearly 100 percent, Thai currency plunge after the bahts free float last July with the Indonesian currency in downward spiral and interest rates shooting northwards, Indian companies with investment in South-east Asia are in the midst of the maelstrom and are desperately scrambling to get a grip of this unprecedented situation even as they wonder: what next? If only they could have got the wind of the disaster things would have been bit different for them. The spate of Southeast Asian currency plunge has sent warning signals to the developing economies to set their level in order to face crisis. Companies have to set their house in order and give a micro as well as macro look at the currency exposure which they are facing. With increase in volume of business in external sector, companies should make themselves tuned to the dynamics of foreign exchange (currency) market. 1.1 Currency RISK MANAGEMENT An asset or a liability or an expected future cash flow stream (whether certain or not) is said to be afflicted with currency risk when currency movement changes (for better or for worse) the home currency value. There is always a possibility of the exchange rate changing between the home and foreign currencies, interest rate differentials widening and inflationary effects amounting, to an adverse reaction for the expected cash flows . The concept of currency risk also emanates when an investor is planning to diversity his portfolio internationally to improve the risk- return trade off by taking advantage of the relative correlation among risks on assets of different countries. This involves investing in a variety of currencies whose relative values may fluctuate , it involves taking currency risks. The foreign exchange market is psychological in nature. A large number of transactions are speculative in nature which depends upon expectations of a large number of participants. People tend to hitch their expectations to one fundamental. For example, they might look at the money supply in the USA. The logic is that an increase in money supply will result in : Þ An increase in inflation Þ FED squeezing money Þ Interest rate rising Þ Dollar becoming more attractive for holding. But this event of money supply could also lead to a different series of outcomes an shown by the following logic. According to fisherman equation, Nominal rate = Real rate + Inflation rate. An increase in inflation would mean the interest rates would be higher. Higher interest rates on bond and equity prices would make them less lucrative and thus lead to a bearish effect. There would be a selling pressure on the dollar and hence the exchange rates would tend to move against the dollar. Dealings in foreign exchange market is said to be around $ 1000 billion each day. Out of this sizeable chunk of more than 75% is on speculative basis. And this speculation has been pointed out as major cause of the south Asian turmoil. Since the mid 1970s a potent mix of fast-interlocking market and a revolution in information technology has increased the speed, frequency and magnitude of price changes in the financial markets, which, in turn have multiplied both opportunity and risk for the CFO. Not, surprisingly, in the developed markets, much innovative energy has been devoted to devising instruments and mechanisms that enable CFO to survive this turbulence. While creative financial engineering has opened the floodgates for a deluge of products, two broad classes of risk management have evolved. The first deploys a natural hedge to manage exposure to risk. Typically, this means explicitly factoring in risk perceptions when choosing the components of the financing mix. Or, to neutralise exposures in a particular market, a natural hedge could involve taking a counter position in another market. The second class of tools however creates a synthetic hedge by utilising specific financial instruments. Notably, derivatives. 1.2 Problems in Indian foreign exchange market Our foreign exchange market suffers from several constraints. i) There are a lot of ceilings on open positions and gaps and hence there is a virtual absence of market making and position trading. ii) There is prohibition of initiating transactions in the cross currency in the overseas market. iii) Besides the forward contracts, there is no free access to the other products like futures, swaps, etc. The market lacks the required liquidity and depth for the derivatives to be economically viable. 2. Literature review 2.1 THE NATURE OF EXPOSURE AND RISK The value of a firms assets, liabilities and operating income vary continually in response to changes in economic and financial variables such as exchange rates, interest rates, inflation rates, relative prices and so forth. The impact of every financial decision on the value of the firm is uncertain and various options can be evaluated in terms of their risk return characteristics. The nature of uncertainty can be illustrated by a number of commonly encountered situations. An appreciation of the value of a foreign currency (or equivalently, a depreciation of the domestic currency)., increases the domestic currency value of a firms assets and liabilities denominated in the foreign currency receivable and payables, bank deposits and loans etc. It will also change domestic currency cash flows from exports and imports. An increase in interest rates reduces the market value of a portfolio of fixed rate bonds and may increase the cash outflow on account of interest payments. Acceleration in the rate of inflation may increase the value of unsold stocks, the revenue from future sales as well as the future costs of production. Thus the firm is ââ¬Å"exposedâ⬠to uncertain changes in a number of variables in its environment. Let us begin with the definition of foreign exchange exposure. Foreign exchange (Currency) exposure is the sensitivity of the real value of a firms assets, liabilities or operating income, expressed in its functional currency, to unanticipated changes in exchange rates. Note the following important points about this definition. Values of assets, liabilities or operating income are to be denominated in the functional currency of the firm. This is the primary currency of the firm and in which its financial statements are published. For most firms it is the domestic currency of their country. Exposure is defined with respect to the real values i.e. values adjusted for inflation. While theoretically this is the correct way of assessing exposure, in practice due to the difficulty of dealing with an uncertain inflation rate this adjustment is often ignored i.e. exposure is estimated with reference to changes in nominal values. The definition stresses that only unanticipated changes in exchange rates are to be considered. The reason is that markets will have already made an allowance for anticipated changes in exchange rates. For instance, an exporter invoicing a foreign buyer in the buyer currency into the price. A lender will adjust the rate of interest charged on the loan to incorporate an allowance for the expected depreciation. From an operational point of view, the question is how do we separate a given change in exchange rate into its anticipated and unanticipated components since only the actual change is observable? One possible answer is to use the forward exchange rate as the exchange rate expected by the ââ¬Å"marketâ⬠to rule at the time the forward contract matures. Thus suppose that the price of a pound sterling in terms of rupees for immediate delivery (the called spot rate) is Rs. 60.000 while the one months forward rate is Rs. 60.20. We can say that the anticipated depreciation of th e rupee is 20 paise per pound in one month. If a month later, the spot rate turns out to be Rs. 60.30 there has been an unanticipated depreciation of 10 paise per pound. In contrast to exposure which is a measure of the response of value to exchange rate changes, foreign exchange risk is defined as. The variance of the real domestic currency value of assets, liabilities or operating income attribute to unanticipated changes in exchange rates. In other words, risk is a measure of the extent of variability in the values of assets etc. due to unanticipated changes in exchanges rates. 2.2 Classification of Foreign Exchange Exposure and Risk Three types of foreign exchange exposure and risk can be distinguished depending upon the nature of the exposed item and the purpose of exposure estimation. These are as follows. Transaction Exposure: This is a measure of the sensitivity of the home currency value of assets and liabilities which are denominated in foreign currency, to unanticipated changes in exchange rates, when the assets or liabilities are liquidated. Transaction exposure can arise in three ways: * A currency has to be converted in order to make or received payment for good s and services. * A currency has to be converted to repay a loan or make an interest payment (or, conversely, receive a repayment or an interest payments) or. * A currency has to be converted to make a dividend payment. Suppose a firm receives an export order. It fixes a price, manufactures the product, makes the shipment and gives 90 days credit to the buyer who will pay in his currency. A company has acquired a foreign currency receivable, which will be liquidated before the next balance sheet date. The exposure affects cash flows during the current accounting period. If the foreign currency has appreciated between the day the receivable was booked on the day the payment was received, the company makes exchange gain which may have tax implications. In a similar fashion, interest payments and principal repayments due during the accounting period create transaction exposure. Transaction risk can be defined as a measure of uncertainty y in the value of assets and liabilities when they are liquidated. Translation Exposure: Also called accounting Exposure is the exposure on assets and liabilities appearing in the balance sheet but yet to be liquidated. Translation risk is the related measure of variability. The key difference between transaction and translation exposure is that the former involves actual movement of cash while the latter has no direct effect on cash flows. (This is true only if there are no tax effects arising out of translation gains and losses). Translation exposure arises when a parent multinational company is required to consolidate a foreign subsidiarys statements from its functional currency into the parents home currency. Thus suppose an Indian company has a U.K subsidiary. At the beginning of the parents financial year the subsidiary has real estate, inventories and cash valued at pound 1,000,000, pound 200,000 pound 150,000 respectively. The spot rate is Rs. 60 per pound sterling. By the close of the financial year, these have changed to pound 1,200,000, pound 205000 and pound 160,000 respectively. However during the year, there has been a drastic depreciation of the pound to Rs. 56. If the parent is required to translate the subsidiarys balance sheet from pound sterling into rupees at the current exchange rate, it has ââ¬Å"sufferedâ⬠a translation loss. Note that no cash movement is involved since the subsidiary is not to be liquidated. Also note that there must have been a translation gain on the subsidiarys liabilities. There is broad agreement among theorists that translation losses and gains are only notional accounting losses and gains. The actual numbers will differ according to the accounting practices followed and depending upon the tax laws, there may or may not be tax implications and therefore real gains or losses. Accountants and corporate treasurers however do not fully accept this view. They argue that even though no cash losses or gains are involved, translation does affect the published financial statements and hence may affect market valuation of the parent companys stock. Whether investors indeed suffer from ââ¬Å"translation illusionâ⬠is an empirical question. Some evidence from studies of the valuation of American multinationals seems to indicate that investors are quite aware of the notional character of these losses and gains and discount them in valuing the stock. for Indian multinational, translation exposure is a relatively less important consideration since the law doe s not require translation and consolidation of foreign subsidiaries financial statement s with those of the parent companies. Operating Exposure: Unanticipated exchange rate changes not only affect assets and liabilities but also have significant impact on future cash flows from operations. Operating Exposure is a measure of the sensitivity of future cash flow and profits of a firm to unanticipated exchange rate changes. Consider a firm that is involved in producing goods for export and or import substitutes. It may also import a part of its raw materials, components etc. A change in exchange rate (s) gives rise to a number of concerns for such a firm. 1. What will be the effect on sales volume if prices are maintained? If prices are changed? Should prices be changed? For instance, a firm exporting to a foreign market might benefit from reducing its foreign currency price to the foreign customers following an appreciation of the foreign currency. A firm that produces import substitutes may contemplate an increase in it domestic currency price to its domestic customers without hurting its sales. 2. Since a part of the inputs are imported, material costs will increase following a depreciation of the home currency. 3. Labour costs may also increase if cost of living increases and wages have to be raised. 4. Interest costs on working capital may rise if in response to depreciation the authorities resort to monetary tightening. In general, an exchange rate change will affect both future revenues as well as operating costs and hence the operating income. As we will see later, the net effect depends upon the complex interaction of exchange rate changes, relative inflation rates at home and abroad, price elasticities of export and import demand and supply and so forth. Operating exposure and the related risk are extremely difficult to analyse, estimate and hedge against. 2.3 THE INDIAN FOREX MARKET Indian foreign exchange market as compared with their American and European counterparts is till in its infants. The post liberalisation period has witnessed many exchange controls been lifted and introduction of few ââ¬Å"hedgingâ⬠tools like cross currency option, Range forwards, currency swaps etc. which provide a degree of flexibility to corporates in using the forex markets effectively. The Rupee has been made fully convertible on current account accepting the article VIII status laid down by IMF. This step has seen increased volume of trade in the Indian forex market. Tarapore committee has put the proposal for capital account convertibility. It proposes to deregulate the foreign exchange by year 2002 in three phases. 2.4 PRESENT STATUS Exchange control in India is administered by the Reserve Bank of India, which is empowered by the Foreign exchange regulation Act. The figure shows the players involved in the foreign exchange market from administrative point of view. Foreign Exchange Regulation Act, 1973 Govt. of India Reserve Bank of India Foreign Exchange Dealers Association of India Authorised Dealers Authorised Money Changers Full Fledged Restricted Administration of Foreign Exchange in India. The foreign exchange market in India functions with a three-tier structure which includes (1) Reserve Bank of India, at the apex level, (ii) authorised dealers/money changers conducting foreign exchange trading activities, and (iii) customers which include exporters/importer, corporates and other foreign exchange earners like NRIs etc. The market is highly influenced by State Bank of India and Reserve Bank of India because of their Sheer Size. The RBI constantly intervenes to keep the rupee from appreciating and is responsible for highly liquid spot market as it is a last resort buyer of dollars. The forward market in India is fairly liquid and quotes are easily available up to six months. The RBI prohibits any international speculative access to rupee. 2.5 SIZE AND DEPTH OF THE MARKET The daily turnover in the Indian Foreign exchange market is over US $400 million that is dominated by dealings in dollars. The foreign exchange reserve of $30 million provides the market with enough liquidity. 2.6 INDIAN EXCHANGE CONTROLS Exchange Controls refer to the regulation, restrictions, guidelines that a country issues with respect to foreign exchange transactions. In the absence of any exchange control one would expect to do anything with the foreign exchange reserves that the company has-convert to any other currency, speculate, buy or sell option, freely export foreign exchange etc. etc. In India, forward contract is the single largest product which the companies employ as a tool to manage their foreign exchange risks, though the cost has changed over the period of time. Before LERMS (liberalised exchange rate management system) importers rushed to book forward contracts expecting a devaluation of Re against US$. The cost was as high as 18% in Feb.92. The cost of the forward premium came down sharply reflecting a more stable foreign exchange markets. The Indian exchange market do not provide frequent quotations for ore than 6 months so for any long term forward cover rollover of the contract after every 6 months is needed. Rollover means cancellation of the old contract and re-booking of 6-month forward contract. Under this, care should be taken to cancel the old contract and re-book the next at the time when the cost of rebooking is least i.e. forward dollar is relatively cheap. Further, in December 1994, RBI has allowed the corporates to bet on the third currency movement even if one does not have an underlying transaction exposure in the ââ¬Å"third currencyâ⬠. This means that a corporate with an underlying exposure in Dollar-Re can bet on the Dm-Dollar rate and book a forward contract for Dm against Re and on the maturity may change Dm to Dollar at the spot rate. This has been allowed as Indian Re has been pegged with US$ and there has not been many fluctuations on which the companies could speculate. There can be other ways to take advantage of this RBI circular. Consider an importer with $ payable after 6 months. He may buy $ forward against Yen (third currency) and after 6 months may buy Yen against Rupee at the spot rate. This position may be taken if the company expects Yen to depreciate against the Dollar within these 6 months. Nevertheless the speculative attempts to earn profits may also backfire to give losses if the exchange rate moves in the opposite direction. RBI has also made it obligatory upon the banks, which extend the third currency cover, to maintain ââ¬Å"initialâ⬠and ââ¬Å"variationâ⬠margins before offering such a facility. This has been done to avoid any default risk. Another peculiar feature of ââ¬ËThe Indian Exchange Control is that the ââ¬Å"hedgingâ⬠can be put through in case of transaction and translation exposures only. Economic exposures cannot be hedged. Cross Currency option was introduced on 1st Jan. 1994, under which companies could enter option contract for hedging non-dollar exposure against dollar. As for now Rupee option does not exist in India. Essar Gujarat has been one of the innovative corporates who discovered this new concept and has benefited considerably by writing option in Dm- Dollar in Jan 1994. Indian Exchange controls do not allow cancellation of cross currency options in parts and once the option is cancelled it cannot be re-booked, unlike forwards. In the overseas markets minimum lot traded is $ 3m whereas Indian corporate by for lesser amount, this increases the premium paid by them for the option. Recently, ANZ Grindlay has offered to arrange a loan of $ 50m to Ranbaxy by making effective use of call and put options to defend both the parties against unfavourable movements in exchange rates. Cross currency forward cover for importers who have taken $ loan for their imports but receive goods invoiced in say a Dm. They can enter forward cover for the delivery of Dm against the currency of loan i.e. -$. This is the cross currency forward cover. Some of the foreign Exchange controls are that export of foreign currency is not permitted, unless it has special RBI permission. ââ¬Å"Exchange controls also they list the permitted currencyââ¬Å" and a method of payment as approved by RBI for translation across the countries. It also contains guidelines relating to ââ¬Å" Foreign currency assetsâ⬠covering permission as for repatriation of capital profits dividends etc. Exchange controls also allow FC to be retained up 50% (in case of EOU EPZ units) and 25% (in case of ordinary exporters with banks in Indian and also abroad under EEFC a/c and FCA a/c. Exchange controls also state under-invoicing and over-invoicing of exports as a crime attracting penal provisions. Further, all sale proceeds in FC should come into the country within 180 days. RBI permission is required for any extension beyond 180 days. In case of failure to get RBIs nod, the tax and other export incentives are not provided to the exporters. Further, exchange controls give details and guidelines for different accounts for NRI and foreign investors such as Ordinary Non- Resident Rupee a/c, Non-Resident External; Rupee a/c FCNR (B) a/c etc. Introduction of complex hedging tools like futures, options is still a long way to go, Recently, the government lifted the ban on futures, option trading in equity (stocks) after 40 years, This could be regarded as a step ahead to come closer to introduction of more complex tools in the currency markets in India. In the near future Standard Chartered plans to introduce rupee-based derivatives in India subject to the clearance and approval by exchange controls, with many companies now making use of different tools effectively, the Indian foreign exchange markets are moving ahead towards more relaxations and towards making the foreign exchange markets more vibrant and versatile, IDBI is one of the most active user of financial derivatives in Indian market. It made considerable savings over the last two year by using the entire range of products available in Indian forex markets. 2.7 FINANCIAL DERIVATIVES USED IN INDIAN MARKET A derivative instrument is commonly defined as one whose price is derived from an underlying quantity that could be an interest or an exchange rate (in this case exchange rate) we refer to derivatives of money and foreign exchange market prices as ââ¬Å"financial derivativesâ⬠. The history of using financial derivatives to hedge foreign exchange exposures by corporates in India is fairly recent. Early 90s witnessed few foreign currency call options written by some Indian corporates. The limited use and general lack of interest in the available instruments can be explained by the fact that dependence on external sources of funding was very limited and the external sector wasnt really developed. But after liberalisation and current account convertibility, the whole scenario has changed. Risk management has under gone a paradigm shift, new financial derivatives have been allowed in the market to provide for exposures arising out of increased business activity in the external sector. We shall discuss the various hedging tools is operative. 2.7.1 FORWARD CONTRACTS The Definition: A forward contract is simply an agreement to buy or sell foreign exchange at a stipulated rate at a specified time in the future. It is a contract calling for settlement beyond the spot date. The time frame can vary from a few days to many years. Instrument: A forward contract locks you to a particular exchange rate, thereby insulating the CFO from exchange rate fluctuations. In India, the forward contract has been the most popular instrument employed by corporates to cover their exposures, and thereby, offset a known future cash outflow. Forward contracts are usually available only for periods up to 12 months. Forward premiums are governed purely by demand and supply, which provide corporates with arbitrage opportunities. The premiums in this market are quoted till the last working day of the month. Internationally, the forward premiums or discounts reflect the prevailing interest rate differentials. Arbitrage opportunities are therefore limited. As a rule, a currency with a higher interest rate trades at a discount to a currency with a lower interest state. Since there is a forward market available for longer periods, the forward cover for foreign exchange exposures can stretch up to five years. The premiums or discounts are quoted on a month-to-month basis. That is, from the spot date to exactly one month, or two months, or even a year. AN EXAMPLE.A corporate has to make a payment of US $I million on March 31, 1998. They can book a forward contract today, and fix the exchange rate at which he will make the payment. Assuming that the dollar-rupee spot rate is Rs 36.40, and the forward premium on the dollar for delivery on March31. 1998, is Rs 0.30 the effective exchange rate for the remittance becomes Rs 36.70 (36,40+30). The Regulations: In March 1992, in order to provide operational freedom to corporates, the unrestricted booking and cancellation of forward contracts, for all genuine exposures, whether trade-related or not, was permitted. In January 1997, the RBI allowed the banks to quote rupee forward premiums for more than six months. This has resulted in the development of a local forward market for up to one year. However, as the link between the local money market and the foreign exchange markets is not strong, and as prices and determined by demand and supply, activity in the long -term forward market has been limited. 2.7.2 FORWARD TO FORWARD CONTRACTS The Definition: A forward -to-forward contract is a swap transaction that involves the simultaneous sale and purchase of one currency for another, where both transactions are forward contracts. It allows the company to take advantage of the forward premium without locking on to the spot rate. The Instrument: A forward-to-forward contract is a perfect tool for corporates that want to take advantage of the opposite movements in the spot and the forward markets. By locking in the forward premium at a high or low level now, CFOs can defer locking on to the spot rate to the future when they consider the spot rate to be moving in their favour. However, a forward-to forward contract can have serious cash-flow implications for a corporate. Before booking a forward-to forward contract a CFO should carefully examine his cash flow position bearing in mind the immediate loss that he would make if the spot rate did not move in his favour. The Example. An exporter believes that forward premiums are high, and will move down before the end of December 1997. Also he expects the spot rate to depreciate in the next few months. Then, the optimal strategy would be to lock in the high forward premium now, and defer the spot rate to a future date. So, he opts for a forward-to forward contract for end December. 1997, to end March of 1998. Paying a premium of say a Rs 0.64 By entering into such a contract the exporter has the opportunity to lock on to the spot rate any time till December 31, 1997. Alternatively, if the three-month premium between end-December and end-March moves below the Rs 0.64 level he can cancel the contract and book his profits. Forward -to-forward contracts The SCenario Company A is due to receive the payment for goods exported three months earlier. Currently, three-month forward premiums are high, but Company A expects the sport rate to depreciate further. The Instrument The forward-to-forward pay-off matrix DS>EF DS>EF Lack in the Current Premium By Purchasing A Forward-To-Forward Contact EF>SF Better Than Simple Forward, But Worse Than Uncovered Strategy Optimal Strategy Choose The Spot Rate Within A Stipulated Time-Period, Thus Determining Effective Forward Rate SF>EF Worst Strategy Better than Uncovered Strategy, At the end of the months, Convert Export Proceeds to Rupee at the Effective Forward Rate SF : Simple Forward Rate EF: Forward-to-Forwar

A Rose for Emily By William Faulkner :: essays research papers
Symbolism in A Rose For Emily William Faulkner (1897-1962) was a southern writer; he spent most of his time in Oxford, Mississippi. "A Rose For Emily" was a vehicle for him to write about the South and the old ways of the South. He was a well respected writer. In 1950 he received the Nobel Prize for Literature. faulkner uses symbolism to make his message stronger. Faulkner uses symbolism as a way to repersent the qualities of the character, places and events in his work. Emily came from a well to do family that had alot of history in the town. The Grierson's were so powerful, Emily did not have to pay taxes. The whole townspeople seemed to think taht they were snobby because in Emily's father's eyes, none of the men were quite good enough for Emily. Unfortunately, Emily turned out to be a lonely old woman because of her father's influence. in "A Rose for Emily", Faulkner uses the element of time to enhance details of the setting and vice versa. By avoiding chronological order of events of Miss Emily's life, Faulkner first gives the reader a completed puzzle, and then allows the reader to examine the puzzle piece by piece. By doing so he enhances the story and presents two different perspectives of time held by the characters such as, the world of the present and, the world of tradition and the past-"confusing time with it's mathematical progression...divided from them by the narrow bottleneck of the most recent decade of years"(Faulkner 35-36). Faulkner uses symbolic elements to compare the Grierson house with Emily's life- "lifting its stubborn and coquettish decay above the cotton wagons and the gasoline pumps-an eyesore among eyesores"(Faulkner 29).

triggering an eating disorder :: essays research papers
* Triggers If people are vulnerable to eating disorders, sometimes all it takes to put the ball in motion is a trigger event that they do not know how to handle. A trigger could be something as seemingly innocuous as teasing or as devastating as rape or incest. Triggers often happen at times of transition, shock, or loss where increased demands are made on people who already are unsure of their ability to meet expectations. Such triggers might include puberty starting a new school, beginning a new job, death, divorce, marriage, family problems, breakup of an important relationship, critical comments from someone important, graduation into a chaotic, competitive world, and so forth. There is some evidence to suggest that girls who achieve sexual maturity ahead of peers, with the associated development of breasts, hips, and other physical signs of womanhood, are at increased risk of becoming eating disordered. They may wrongly interpret their new curves as "being fat" and feel uncomfortable because they no longer look like peers who still have childish bodies. Wanting to take control and fix things, but not really knowing how, and under the influence of a culture that equates success and happiness with thinness, the person tackles her/his body instead of the problem at hand. Dieting, bingeing, purging, exercising, and other strange behaviors are not random craziness. They are heroic, but misguided and ineffective, attempts to take charge in a world that seems overwhelming. Sometimes people such as diabetics who must pay meticulous attention to what they eat become vulnerable to eating disorders. A certain amount of obsessiveness is necessary for health, but when the fine line is crossed, healthy obsessiveness can quickly become pathological. Perhaps the most common trigger of disordered eating is dieting. It is a bit simplistic, but nonetheless true, to say that if there were no dieting, there would be no anorexia nervosa. Neither would there be the bulimia that people create when they diet, make themselves chronically hungry, overeat in response to that hunger, and then, panicky about weight gain, vomit or otherwise purge to get rid of the calories. Feeling guilty and perhaps horrified at what they have done, they swear to "be good.

physiotherapeutic management of stroke :: essays research papers
Introduction Cerebrovascular disease or the term stroke is used to describe the effects of an interruption of the blood supply to a localised area of the brain. It is characterized by rapid focal or global impairment of cerebral function lasting more than 24 hours or leading to death (Hatano, 1976). As such it is a clinically defined syndrome and should not be regarded as a single disease. Stroke affects 174-216 people per 10,000 population in the UK per year and accounts for 11% of all deaths in England and Wales (Mant et al, 2004). The risk of recurrent stroke within 5 years is between 30-43%. One problem is that the incidence of stroke rises steeply with age and the number of elderly people in the UK is on the increase. To date people who experience a stroke occupy around 20 per cent of all acute hospital beds and 25 per cent of long term beds (Stroke Association, 2004). The British Government now identifies stroke as a major economic burden on the National Health Service (DoH, 2002). Fifty percent of stroke survivors will experience some residual impairment (physical and cognitive), which is devastating to the individual and their families (Rudd et al, 2002). It is therefore vital for patients and resources that maximum functional recovery is achieved as fast as possible. The physiotherapist has a key role to play in the management of stroke patients, through assessment, prevention strategies, acute management and recovery. This essay aims to critically discuss physiotherapeutic management and examine how it has and may be influenced by a number of factors (e.g. type of organized system for the delivery of post stroke care, setting of therapy, evidence based practice from which National Guidelines are produced etc). The first stage is to outline stroke pathology, of which forms the basis of appropriate management. Pathology There are two major stroke sub groups, those resulting from infarction (ischemic stroke) and those resulting from haemorrhage (intracerebral and subarachnoid). Each of the types can produce clinical symptoms that fulfil the definition of stroke. The types often differ with respect to survival and long-term disability, from recovery in a day to incomplete recovery, severe disability and death (Warlow et al, 2001). Ischemic stroke is the most common type of stroke, which accounts for approximately 85% of all cases (Rudd et al, 2002). It affects 35 people per 100,000 of the population per year (Coull et al, 2004).

Simple Reasons Why Some People Canââ¬â¢t Write Essays
There are some students, perhaps those that you may know, that canââ¬â¢t seem to write essays. There are some people that will seem to have it all down to a science, while some people will not know how to complete a full blown essay of any type. Youââ¬â¢re going to find that there are a lot of reasons why this is prevalent. If youââ¬â¢re looking at writing, and are having a hard time overall, you may want to look into a few reasons why some have a hard time. The following solutions will help you focus on how to get moving forward with the process of gaining the upper hand in writing essays. Itââ¬â¢s going to focus on why some people canââ¬â¢t write, which will then help you correct mistakes that you may be facing off against. These are the simple reasons why some people canââ¬â¢t write essays, which should help you gain the upper hand. Once you know what to work on, you will be able to address those things and correct them moving forward.Ideas Donââ¬â¢t Come Quic kly Some people have a hard time brainstorming ideas and topics. Some donââ¬â¢t really know what to write about or where to even start. Even with a simple prompt, many people arenââ¬â¢t sure how to develop the ideas that an essay requires. In academia, thereââ¬â¢s a lot of focused solutions that come through, and finding a way to organize the right ideas into a narrative that works is tough, to say the least. Narrowing down the options is difficult enough, but getting to a point where youââ¬â¢re working on one thesis statement and then creating proper annotated essay elements can become a struggle, which causes many writers to give up before they even get too far in the writing process.Many Students Donââ¬â¢t OutlineThe process of writing an essay should not be done by sitting down at a word processor and going forward. Thatââ¬â¢s the mistake a lot of students make, and itââ¬â¢s not a good thing. To master essay writing, you have to focus on outlining, and creat ing ideas that are easy to work with after the fact. Sitting down and trying to write is not going to help forward progress, itââ¬â¢s just too difficult to do that. Many students try to do that, but end up losing focus because they donââ¬â¢t have a path towards the finish line, which is why outlines matter so much.Students Donââ¬â¢t Like EditingA lot of students fail at working well with writing essays because thereââ¬â¢s an editing process that many donââ¬â¢t like. Editing means changing things, and facing off against writing options that arenââ¬â¢t very good to run through. Students often assume that the writing process takes one major push, and thatââ¬â¢s it. But thatââ¬â¢s not true. In order to sustain the path of good academic writing, a student has to write a rough draft, then edit it down and consolidation ideas to fit the format of the prompt. In some cases, over extending the writing is not a good thing, which is why editing is so important. Students often donââ¬â¢t like to edit, because it feels like they are erasing the hard work that theyââ¬â¢ve been working through.Reading Comprehension Is RoughFor some individuals, the process of reading and comprehending different view points can be difficult to manage. To the point where writing an essay can become somewhat difficult. Writing an essay is made even more difficult when you have to cite sources, and comprehend what others have done within certain academic criteria. Reading comprehension is one thing, but taking the information that one has read and then rewriting, citing it, and creating a greater push forward regarding the writing process can be a bit difficult.Length and Word Counts Are IntimidatingThere are some students that look at the prompts and word counts associated with essays and become intimidated by them. There are some essays that arenââ¬â¢t that long, only around 500 to 1000 words. However, there are some options that require a lot longer of a push. For instance, graduate study work could need upwards of 10,000 words, and they all need to be cited in certain style. Citations and references alone could be several pages, and thatââ¬â¢s not including the actual essay formatting. Length and word counts can easily be intimidating when a writer finds that they have been working for hours, and may only have around 700 or 800 words. Crafting long form essays can be daunting for the novice, and for others, it could be a major hurdle that they cannot seem to overcome with relative ease.Waiting Too Long To StartThe moment that an essay is assigned, the student should chase the option to start working on it. Many students wait too long to start, and end up trying to cram all of the writing into one night. This is a mistake that many people make, and it becomes an impossible task to work out. Waiting too long to start is a bad idea because the editing process becomes difficult to manage, and it becomes even harder to work through ideas, thesis statements and more. Procrastination is the enemy of students, especially when it comes to writing essays of an academic format.Rushing Through The ProcessSome people can write a lot in a short time, but when it comes to proper formatting, and essay writing, they seem to find themselves lacking the appropriate time frame to work on the essay prompts. Rushing through the process, forgetting drafts, outlines, and editing is a part of the bigger problem as to why people canââ¬â¢t write proper essays and seem to have a difficult time progressing through a variety of different arenas. Writing essays is tough, but when you rush through any of the writing process, it becomes a lot more difficult to put together the appropriate structure. At the end of the day, thereââ¬â¢s a lot of reasons why people canââ¬â¢t seem to write essays. The above are just some of the most common issues that people have.
