Discuss the main features of Austrian government, politics and Essay

Talk about the fundamental highlights of Austrian government, legislative issues and parliamentary majority rules system today - Essay Example Presently, Austria passed a law proclaiming unending nonpartisanship and a restriction on entering any military unions or permitting remote army installations on Austrian region. In its job as an impartial state, Austria saw itself as an extension between the East and West during the Cold War and facilitated various United Nations offices and worldwide associations in Vienna. In spite of its political nonpartisanship, be that as it may, Austria remained firmly lined up with western popular governments both socially and ideologically. In a June, 1994 submission, 66% of Austrians showed their kindness for EU participation, which prompted the marking of the Treaty of Accession of Austria to the EU on June 24, 1994. This Treaty hence went into power, and Austria turned into an individual from the EU on January 1, 1995. Directly, Austria is one of the wealthiest EU Members. Over 60% of the country's imports and fares originate from or go to other EU nations, rendering the country's economy to a great extent reliant on the EU. Presently, Austria is one of eleven EU Member States that has received the Euro and, therefore, it has actualized a financial arrangement as per European Monetary Union necessities. Generally, Austria's economy worked as a corporatist arrangement of 'social organization' between government, industry, work, and horticulture. In the 1980s, nonetheless, the administration's job started to melt away because of the privatization of numerous undertakings previously under state possession. The administr ations division overwhelms the economy, and the travel industry creates around 15% of the country's capital. Over 9% of Austria's populace is considered outside, with networks of ethnic Magyars and Croats living in the area of Burgenland and Slovenes in Carinthia. By and by, 98% percent of Austrians communicate in German.30 In 1996, in excess of 700,000 foreigner specialists were enlisted in Austria, and an obscure number of illicit settlers and displaced people by and by live there. AUSTRIA'S POLITICAL SYSTEM has been a model of dependability since majority rule government was reestablished in 1945. As opposed to the interwar period, when local political competitions and outside mediation brought the arrangement of government set out by the constitution of 1920 to a halt, after World War II this restored parliamentary vote based system worked easily in what came to be named the Second Republic. Now and again, Austria's political framework appeared to be impenetrable to change, however by the center of the 1980s, it had become certain that expansive social and monetary patterns were starting to influence the nation's legislative issues. Austria is a parliamentary spoken to popular government containing nine administrative states and is one of six European nations that have announced changeless lack of bias (An unbiased nation takes no side in a war between different gatherings, and consequently wants to abstain from being assaulted by both of them. A neutralist strategy focuses on lack of bias in the event of a furnished clash that could include the gathering being referred to. A neutralist is a backer of lack of bias in worldwide issues) and one of only a handful not many nations that remembers the idea of everlasting nonpartisanship for its constitution. Austria has been an individual from the United Nations since 1955 and joined the European Union in 1995. At the point when Austria joined the EU in 1995 a submission must be held on the grounds that the increase was qualified as a key change

How to Learn to Code

How to Learn to Code Computer programs used to be something only the programmers understood. But with the technological revolution, we can all become computer programmers from the comfort of our own home. But should we learn to code? © Shutterstock.com | lassedesignenThis guide explains what coding is and why it’s a skill that can be useful for many entrepreneurs. We’ll also provide tips on how to learn to code, whether you want to learn on your own or take a course.WHAT’S CODING AND WHY SHOULD YOU LEARN IT?If you are unfamiliar with coding, here’s a short introduction to what it is all about. Code is a language used to write computer programs, apps and websites. Without code, you wouldn’t be able to access websites or use your computer. In fact, coding isn’t limited to just your computer and mobile phone. Almost any device that uses electricity will need code to work. This includes cars, watches and microwaves.When you are coding, you are creating a set of instructions, which the device can understand. These instructions ensure the program or device runs as it should.Similar to the different languages humans speak around the world, coding can use a variety of languages as well. Some of the most popu lar coding languages include:CC++JavaPythonVisual BasicRubyAlthough a computer runs on a binary code (written in 1s and 0s), it can understand a variety of these other languages. Furthermore, many of the above coding languages share similarities and have developed by using the characteristics of different languages.Here’s a great video about picking the best programming language as a beginner: The benefits of knowing how to codeWhy should you learn how to code? Just like knowing English, as the lingua franca of the world, can help you travel around the world, understanding coding can enhance your understanding of the world of technology. As our lives become increasingly immersed with coding, the importance of understanding it becomes amplified.Coding is the future. But the ability to code doesn’t just mean you are more equipped of understanding the world around you, it can also have significant benefits for your career. Not only are many IT-related jobs requiring a certain level of coding knowledge becoming more prevalent, your actual earning potential can increase if you learn to code.The coding world is full of opportunities. Since it’s not yet a mainstream subject to study, coding can open up plenty of business opportunities. Furthermore, coding can be done from anywhere in the world. All you need is a computer and an internet connection. In terms of launching a business, this can be a huge advantage. Areas such as web design or app development can be performed miles away from the actual client.Even if you don’t want to pursue a career purely involved with coding, learning to code can provide you other transferable skills. Coding teaches you creativity. You’ll need to be able to think outside the box to create innovative programs and solve the problems you might have in your code.In other words, one of the noticeable benefits of coding is the way it improves your thinking and problem solving skills. Coding is about solving problems and the more yo u do it the better you become at looking for solutions. Apple’s founder Steve Jobs, once said in an interview, “I think everybody in this country should learn how to program a computer because it teaches you how to think”.Coding is truly an investment in the future. Whether you turn it into a career or a business, or simply enjoy the benefits of basic coding knowledge, the advantages will be clear.DO IT YOURSELF OR GET TAUGHT BY PROFESSIONALSWhen it comes to learning to code, you have two basic options: you can teach yourself to code or take place in a professional course.Before we move into looking closely at the costs associated with these different options, you should first determine whether to study alone or not.Doing it yourselfWhilst coding can seem like a complicated ‘language’, it is possible to learn to code on your own. You just have to go to Google and type in “learning to code alone” and you’ll see hundreds of results of people explaining how they managed to do it.Learning to code on your own is possible in today’s world, because people are sharing information and tips online. There are coding blogs, videos on YouTube and a number of online forums purely dedicated to coding. Moreover, there are more than enough computer-coding books available. In the following sections, we’ll highlight more options for learning on your own.The positives of learning coding on your ownJust like with any self-study, learning to code on your own has its benefits. Among the top ones is your ability to decide when to code. You won’t have schedules or deadlines to keep you busy. If you want to practice Java at 3a.m. in the morning you can do the exercises during your lunch break.For certain types of people this ability to decide the pace of studying can be highly beneficial. If you are a fast-learner, you can learn the basics in a week or if you need time to process everything, it’s OK to learn for a year. If you roll into a course, you often don†™t have the luxury of deciding.Finally, it might be easier to learn to code whilst also working, if you do it on your own. Since you can schedule the studying around your normal routine and work, you’ll have more flexibility.The downsides of learning to code on your ownBut self-study isn’t for everyone, as it can be quite difficult to master a new skill on your own. If you are not computer literate, then coding can seem puzzling.Whilst self-studying can be flexible, it does require plenty of effort. You’ll need to find all the study materials yourself, which will be more difficult as your skills advance. Browsing through forums just to find an answer can seem frustrating, especially as a teacher might be able to give a proper answer in 10 minutes.Although certain types of people feel more motivated studying alone, others can find it less motivating. When you are not obliged to study, it can seem more enjoyable to visit the cinema with friends rather than debugging your code.Ta king a professional courseIf self-study doesn’t appeal to you, you can enroll in a coding course. There are both online and offline options available, providing you enough flexibility to pick a suitable option.Whilst professional courses tend to come with a price tag, there are free alternatives. There are online sites offering free courses, but your local community groups might also provide free offline study groups. The below section will talk about these free options in more detail.You should also note computer coding courses aren’t just for the young people. It’s possible to find dedicated groups for small children as well as older learners.The positives of learning coding by taking a courseThe main benefit of taking a coding course is the level of personal information and guidance you receive. You’ll have someone to answer your code-related questions and guide you through each step of the process. You won’t need to spend hours at a forum trying to understand a problem , but can simply ask and receive instructions.You’ll also receive constant feedback on how you are doing. This feedback can be important when learning to code, as you will progress faster. Not to mention the motivating impact feedback can have on your studying speed.The fun side of learning at a course is the other students you have around you. These people will be at a similar level to you in terms of skills and you can get support and encouragement from the group.The downsides of taking a courseHowever, enrolling in a course is less flexible than studying on your own. You can’t often choose from many options of timing and this can be difficult in terms of your work and personal life. While online courses can provide bit more flexibility, they still can have specific assignment deadlines or video seminars, you might want to attend.Furthermore, professional courses tend to cost money. Although free options are available, the more you want to study the likelier it is you’ll nee d to pay. The problem is that not all courses are as effective as others. Therefore, you might end up paying for a course and come out with unsatisfactory understanding of the subject.LEARN TO CODE FOR FREEYou also have the option to choose between paid and free options. The internet has truly revolutionized the way we obtain, share and use information, providing plenty of opportunities to learn to code without paying a penny.First, you should find your way to websites, which offer free coding tools.

The distance that is created between the captain and his crew due to the rules and limits will not be as strong when it comes to a father and his kids; his eternal love for them will allow him to break the rules sometimes.The kids love for their father will allow them to get closer to him; closeness that can never exist between a captain and his crew. Whitman sees Lincoln as the captain of the ship but also as the father of the citizens. To him, Lincoln was a unique leader; he had the qualities of a captain and the qualities of a father. Lincoln was able to set the necessary rules and restrictions in order to overcome the challenges arose by the civil war. He knew how to lead the country in the right direction towards victory. But, he was also a father.Every one of his acts and decisions were enveloped with true love towards his citizens. I have recently watched the movie Dead Poet society. The movie talks about an English teacher who comes to teach a group of privileged students. Through out the movie, the students refer to their new teacher as their captain. They feel for their teacher what Whitman felt for Lincoln. They view the teacher as the person who guides them through the learning process of poetry, but they also, like Whitman, feel that every act or step that was made by the teacher is enveloped with love for his beloved students.Whitman refers to Lincoln as a father only in the second and third paragraphs but not in the first one. The first paragraph talks about the victory, the steadiness and the happiness of the country and its citizens. Whitman doesn’t see Lincoln in his weak moments; he sees him as a captain, a strong figure that every one admires. The other two paragraphs talk about the death of the strong man, the captain. In these moments, Whitman feels close to him, he cares for him like a son cares for his dying father; he wants to help him.

Short

Introduction The management in any organization is often charged with the responsibility of planning, organizing, controlling and leading all the resources of the organization in the most effective way to ensure its secure and sustained growth in all its future years of operation. Every approved investment decision should portray the projected effect on the firm’s future by use of the various established assessment procedures.Advertising We will write a custom essay sample on Short-term decisions lead to the emergence of the global financial crisis specifically for you for only $16.05 $11/page Learn More Moreover, any investment which risk assessment cannot be articulately determined as per the existent procedures should be stalled irrespective of how promising its returns may be. After the recent global financial crisis, it is evident that most firms, even the key financial organizations in a country, make investment judgment based on the short-t erm rather than the long-term. Over the years, since the great depression in the 1930’s, the role of management seems to have diverted significantly from expectations as illustrated by the global financial crisis. Managers, particularly in financial institutions and mortgage firms, have made decisions based on the current environmental changes and without much consideration of the long-term effects of each decision. Investment alternatives that seemed promising in the first few years, turned out to be the causes of the global financial crisis in later years. The form and level of risk management by these firms has been based on short-term assessment methods that have been nullified by the succeeding events. On the same note, there were financial institutions in certain countries such as Canada that did not suffer adverse effects of the crisis. Their management decisions were sound and based more on the long-term than on the short-term. In this easy, I intend to illustrate how certain management decisions by the top financials institutions fueled the emergence of the global financial crisis and how alternative management decisions by other firms cushioned them against the adverse effects of this crisis. Finally, I will elaborate on the managerial lessons from this occurrence that could be exploited to help reduce the recurrence of such an event in the future. Managerial decisions that fueled the global crisis According to Perelman (2012), the state of the economy in the 1920’s was so weak that any single occurrence could have triggered the Great Depression. This implied that short-term managerial decisions made by the financial institutions have certain minor but progressive long-term effects which accumulate to a certain level when a single occurrence can lead to fatal crisis. I think the global financial crisis of 2008 was due to the same reason. The US housing bubble is often regarded as the proximate cause of the crisis. The management of Mort gaging institutions allowed the prices of the house to increase alarming since more inflows were attractive. No efforts were made to alter the condition. According to Tymoigne (2011), these institutions did not consider how the changes in prices would affect consumer spending and savings rate in the long run. The high cash outlay on housing had the effect of increasing the household’s spending causing them to save little no money.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Some began defaulting on their very first mortgage payments, a new occurrence in the sector. Such events occurred in Spring 2007. Managers of the subprime mortgages should have recognized something wrong and acted upon it. However, their actions to avert the situation were based on the unexplained belief that the housing prices never decline and the noble decision to ensure that more people own their homes. Th e later was ineffectively executed. Moreover, the continued deterioration of the credit principles that were applied to complex mortgage instruments also amplified the bubble. Managerial decisions in the lending process are aimed at helping people purchase homes in the short run that they ignore the requirements of the lending process. Schenk (2011) argues that loans were granted without the relevant review procedure or without verifying their income sources or securities. All along, the house buyers depended on the house rentals to pay for the mortgage. Later, the mortgage would be used as security to secure loans form non-bank lenders. These lenders, on the other hand, did not hold the mortgages to maturity. Instead they sold them off to the investors. Such incentives had the effect of enticing the home buyers to increase their debt to the extent that they could not afford. The later managerial decision by the U.S. financial institutions to organize the pooling of the above subpri me loans with the aim of strengthening security issuance was not carefully researched. Crump ( 2011) recognizes that had the professionals in this reputable analysis surveyed the process meticulously with a bias on the long-term effects, they would have seen no need to pool the mortgage loans. These may have saved the situation or allowed more time for the implementation of measures to safeguard against the global crisis. The Federal Reserve management was aware of the possible eventual default on the subprimes but preferred to focus their attention on the positive news of the housing industry. According to Prager (2012), a member of the Fed board had shown an optimism in the transition of the US economy to a modest and sustainable speed. This would ensure sustained non-inflationary development. He had perceived that the burst in the bubble would not spill over since the subprimes were worth less than two billion dollars. What he did not perceive is that the subprime was large relat ive to the US Gross National Product and the number of defaults was increasing greatly. Therefore, the spill in the long run would have resulted in the insolvency of the financial institutions that held them.Advertising We will write a custom essay sample on Short-term decisions lead to the emergence of the global financial crisis specifically for you for only $16.05 $11/page Learn More Similarly, the United States’ yearly decision to finance its annual budget deficit through government borrowing from other nationals had led too a great liquidity in the financial system causing the housing bubble. As Schenk (2011) says, government borrowing was a short-term decision meant to supplement the annual budget. Though the purpose was achieved in the short-run, the long-term effect of too much liquidity and huge debt greatly fueled the emergence of the global crisis. The amount of subprimes was, thus, large relative to the country’s debt leading t o the mortgage anomaly. He further added that the loopholes in supervisory system of emerging nations could have been excused. However, he fails to understand why the US, a model regulator could have failed to foresee such an eventuality. Credit suppliers had opted to use the normal evaluation procedure in the determination of the complex credit facilities in the short-term. They may have instituted measures to come up with the right procedures to evaluate such credit facilities but this did not shield them from the adverse effects of their short-term decision. According to Wade (2011), the credit risk was under-priced, a feature that caused the credit suppliers to be undercompensated for the risk. In due process, the credit spread across the board reaching to extremely thin margins. This further aggravated the appetite for greater credit risk and thus forfeiting the opportunity for correction of the global economic imbalance through the credit markets. Economists such as Adam Smith had long recognized the importance of leverage check in organizations. However, over the years, financial institutions lost a reasonably simple task of defining and determining the leverage due to their short-term mindset. They anticipated that if checks had not resulted in any anomalies in the period they were not conducted, then they would not do so in the few years to come. As Wade (2011) says, the astronomical growth of activities to acquire more securities, were majorly conducted off the balance sheet. Many of the financial products offered by these institutions contained leverage that was too difficult to evaluate or the classes of leverage were layered upon each other to the point of spreading the loss to even the most refined market players. Another reason attributed to the financial crisis is the shortcomings connected to the risk management in the private sectors, and a misunderstanding in the public sector. Schenk (2011) says, few managers had noticed the looming crisis by the summer of the year 2007. Many management decisions were based on what other firms were doing rather than by what was the right thing to do. Unfortunately, these decisions were based on faulty technical issues on the risk assessment.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More For instance, many supervisory authorities had failed in their duty in monitoring the risk situation in their firm’s activities, a circumstance that indicated the industry practitioners were overdue in reporting the matter to the top management. Moreover, the management failed to appreciate the forms of liquidity intermediation in time so as to act since they only thought in the short-term. So far I have managed to argue how the different managerial decisions either taken or not taken due to a short-term perspective of the financial institutions’ operations led to the emergence of one the financial crisis often termed as the worst in the history of the world. To further discuss the matter, I will illustrate how certain managerial decisions in Canada had significantly reduced the effect that had the global crisis to their economy. This will substantiate my earlier claim that managerial decisions in reaction to the consistently changing environment that lay emphasis on t he short-term were the real problem behind the economic crisis. Canada and the global crisis Unlike other countries, Canada which is a good example of a middle-sized, sophisticated capitalist economy has a banking system that survived the great financial crisis. Though it is also felt the heat of world recession, the country weathered relatively better than all other nations. Despite a mild hit on the financial institutions, there was no need to inject more funds into the system, the banks retained their level of profitability and shockingly managed to continue with their lending culture as usual. So what managerial decisions did they take into consideration? It is vital to note that their practices were often criticized by the U.S. and the U.K as conservative since they were not opened up to new financial advancements. Canada has instituted a regulatory management of banks, insurance agencies and large investment dealers under the Office of the Superintendent of Financial Instituti ons (OFSI) that meet regularly to ensure that there is a sound and stable management of the financial institutions. According to Schenk (2011), having the securities firms bank-owned and the OSFI to monitor the operations of the banks keeps the operations checked to avoid similar occurrences to those of U.S. the regular meetings ensure that all looming issues are deliberated upon based on their long-term effects on the economy. Pertaining to the issue of leverage, the managerial decisions by regulatory authorities on the leverage were stricter on asset-capital ratio. As Nanto (2010) says, they did not allow their companies to exceed 20 to 1 ratio. This decision was reached based on analysis of what effect the ratio greater than 20 to 1 would have on the economy at large. Therefore, at the time of the global crisis, the Canadian banks had asset-to-capital ratio of 18 to 1 which was less that of their U.S. and European counterparts. The U.S. multiple was over 25 while that of the Euro pean counterparts was above 30. Being less highly leveraged helped Canada survive the economic turbulence of 2008. Canadian mortgages were given by the banks to hold in the long-term unlike their US counterparts that were intended for resell to the investors. Ciro (2012) argues that this acted as an incentive to only lend in situations where there was high likelihood of repayment more than that of default. The banks were more articulate in assessing the income sources of the home buyers and their corresponding securities to ensure the probability of default was almost zero. Therefore, when the home buyers began to default in the U.S. and U.K, the Canadian financial institutions were collecting their mortgage repayments as usual. Their purpose to hold the mortgages for the long-term cushioned them from the adversities of the global crisis. Financial institutions in Canada have huge capital requirements as compared to those of other nations such as the UK and the US. Its banks depend more on the depository funds, which they maintain well above the required level, to safeguard them against emergence of volatility in the market. This is a decision that carries factors in the long-term effect of the ever-changing environment. Lev Ratnovski quotes this as the reason why its banks are classified among the most resilient in the world. Moreover, he adds that this form of framework is to be accredited for the solid statement of accounts, low foreign debt and a very sound national pension plan despite the current population situation. So far, I have illustrated that with the proper managerial decisions putting emphasis on the long-term rather than short-term, it was actually possible to survive the global financial crisis. Canada was faced by the very crisis that faced all other nations. However, it was left less scathed than the US and other European nations. This implies that a global financial crisis is not an event that cannot be avoided. Rather it is an eventuality which can be checked by using the right managerial decisions. Having identified that is not satisfactory. We need to know what to do when we are confronted by a similar crisis or what measures to institute to prevent the likelihood of such an occurrence. Therefore in the next section we look at the managerial lessons form the global financial crisis and in particular from survivors such as Canada. Managerial lessons There are several observations from the economic crisis that can provide a valuable lessons for the future practices. First, it is the interdependence of the macroeconomic behaviors and systems. Discreet long-term monetary policies have a desirable effect on the financial sectors while short-term macroeconomic policies that lead to global imbalances can bring to any financial markets irrespective of how effective the regulatory systems are. According to Schenk (2011), it would be wise to come up with exit strategies that ensure that the short-term policies do not create global imbalances. He adds that there is need for timely warning should there be such imbalances both nationally and internationally. This will ensure the high real interest rates are equally matched by the full pricing of risk. Second, globalization and the markets has shaped to be well comprehended in their complexity. These can be ensured by enhanced communication between regulators both at the national and international levels. This will foster the identification of problems that may result form short-term decisions by the institutions and deliberation on the most appropriate wais to safeguard the future against another global crisis. Third, prudence may be too righteous and boring but the pay off is worthwhile especially when the product is evaluated throughout the whole economic cycle. The worth and efficiency of the net systems have to be determined throughout the business cycle and not during the growth period only. Evaluation at a particular phase would only suite the short -term which we have seen is disastrous. The level of customer confidence in Canada and the U.S. brought the differences that occurred in the recession. One country was cushioned form the extreme shocks while the other was devastated by the crisis. The effectiveness of the regulatory authorities will depend on the line of defense of the firms. This calls for firms to have their practices imbedded in its corporate governance structures and policies. The policy makers need to be cautious in complicating any perceived reforms as the simplest policies are of ten the most effective. Canada’s 20 to 1 asset-to-capital ratio may have been simple but it was definitely effective. Another vital aspect is the depository requirements by the banks. The reforms should increase the amount and quality of reserves that the financial institutions should hold. The amount should reflect the all the long-term eventualities of the market. According to lynch, this principle is widely accepted by the principles but the issue of how much is enough has caused lost of disagreements. This may not be accurately determined though all efforts (Bustillo and Velloso, 2009). Conclusion I have argued in the easy that the organization’s operations while laying emphasis on the short-term were to be blamed for the global financial crisis. First, I illustrated how financial institutions had either ignored the market tends that gave hints on the possibility of a crisis or made short-term decisions that worsened the situation. Then, to illustrate that it was possible to emerge unscathed from the global financial crisis, I have used an example of Canada, an advanced capitalist economy, that was almost unaffected by the crisis. I have evaluated its strategies in comparison to those of other nations so as to underscore the difference. Lastly, I have made some recommendations on possible long-term managerial lessons, which if followed would ensure such events do not reoccur in future.

Short The preservation of the human rights is one of the main tasks of any government. However, where is the solution to the question which involves the preservation of the population’s interests, but breaks the human rights? This controversial issue is closely connected with the problem of Aboriginals in Australia.Advertising We will write a custom essay sample on Short-Term and Long-Term Consequences of Removals for the Indigenous Children specifically for you for only $16.05 $11/page Learn More Moreover, the issue of the Stolen Generations is still current for the Australian society because the consequences of the forcible removal of indigenous children can be observed even today. That is why it is important to focus on determining short-term and long-term consequences of removal for those children who became the victims of the governmental discriminative policy in Australia during the period of 1890-1970. The fact of the forcible removal of indigeno us children from their aboriginal families is discussed by many researchers today. In their work â€Å"Women and Human Rights in Australia†, R. Desai, S. Fascione, J. Fox, and D. Kogan present the overview of the development of women’s rights in Australia in relation to the phenomenon of the Stolen Generations (Desai, Fascione, Fox, Kogan, 2008). The authors make accents on the formal aspects of women’s socio-political organizations in Australia and connect their development with the progress of social movements associated with the problem of human rights in Australia from the perspective of the issue of the Stolen Generations and results of this process. However, presenting the definite background for the development of the social organizations and movements in Australia, the authors give only general and brief information about the phenomenon of the Stolen Generations without concentrating on its consequences. Thus, the reasons for developing the violent acti ons against aboriginals were hidden in the governmental inclinations to realize the principles of assimilation in the Australian population with the help of providing discriminative measures (Desai, Fascione, Fox, Kogan, 2008). If the reasons of the process are historically explained, the consequences of removals for the representatives of the Stolen Generations require their further analysis. These consequences can be discussed as short-term and long-term ones. Many researchers determine such aspects of the process as the inclinations of the authority to create definite conditions for civilizing the indigenous children.Advertising Looking for essay on social sciences?

The short-term results of such actions could be observed in the children’s inability to adapt to new circumstances, in their diseases as the results of stresses and changing the life conditions (Cassidy, 2006). The most dangerous effects were connected with the violent actions of white people who took children in their families. Aboriginals were considered as servants and often suffered from different kinds of abuses including sexual abuse (Kennedy, 2001). Various discriminative actions which were directed against the indigenous persons became the causes for children’s different psychological traumas which were complicated with the fact of their isolation from their relatives and cultural background (Krieken, 2004). Thus, when such children became adults they suffered from their impossibility to be culturally identified (Rayner, 2003). Moreover, the society rejected to accept the indigenous persons as equal to the other Australians in rights, and it was the reason for the development of the further hostility and violence against the Stolen Generations (Zogbaum, 2003). Thus, these people could not bear the facts of racial discrimination and being depressed could not find their place in the Australian society. That is why the rate of suicides among the representatives of the Stolen Generations is rather high (Read, 2003). The problem of the Stolen Generations is an example of providing the forcible assimilation and discriminative policy which is tried to be explained by the needs of the oppressed people.

Critically Examine The relationship Between Ethnicity and Health The WritePass Journal

Critically Examine The relationship Between Ethnicity and Health Introduction Critically Examine The relationship Between Ethnicity and Health IntroductionReferencesRelated Introduction The policy makers are concerned with addressing or correcting imbalances that impact directly on ethnic minorities’ well-being, such as socioeconomic, health, housing, education, lifestyle and discriminatory factors. Aggleton (1990, p.5 as cited in Baggott, 2004) posited that health can be defined in two ways; ‘‘the positive approach, where health is viewed as a capacity or an asset, and the negative approach, which emphasises the absence of specific illnesses, diseases and disorders’’. Similarly the World Health Organisation (1946 as cited in Baggott, 2004) defined health as ‘‘a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity’’. This definition is significant in that it highlights physical as well as mental aspects of health while emphasising the ‘positive sense’ as in Aggleton’s definition of health. According to Giddens (2009, p.633) ‘â⠂¬Ëœethnicity refers to the cultural practices and outlooks of a given community of people which sets them apart from others’’. Ethnic groups have different traits that set them apart from other groups, such as religion, dress style, language, and history. However, ethnic differences are learned to an extent there have been associations made with health for most of these minority groups. While there is nothing innate about ethnicity, it is central to group and individual identity and similarly important to the health professions who suggest there is a relationship between health and ethnicity. Giddens (2009) argues that this relationship is partial at best but concedes that there is a rather high incidence of illnesses among individuals or groups of ethnic origins. This essay will critically examine and explain the relationship between ethnicity and health. In Britain as the 21st century progresses, its population composition of ethnic minorities is rapidly changing, despite Queen Elizabeth the 1st’s proclamation in 1601 that ‘negroes and blackamoors’ should be deported. She believed they were responsible in part for the social and economic dilemmas, such as famine and poverty (Haralambos Holborn, 2000, p.199). In contemporary Britain this contentious issue has continued amongst a mass population about what they believe to be ‘Britishness’ when it comes to ethnic minorities. According to Stillwell Van Ham, (2010) some see it as a disaster, which will lead to spatial segregation, communities breaking down and a burden to the health delivery system. Perhaps this could be explain why extreme right-wing parties such as the British National Party, which contests immigration and blames all social predicaments on ethnic minorities continues to attract support.   While others will argue that this will be goo d in terms of diversity and see it as an opportunity for an integrated society (Stillwell Van Ham, 2010). There are various ways in which health and ethnicity are related. For example there are differences in population structures, education, genetics, generational and socioeconomic factors between different ethnic groups that impact differently on their health (Bardsley, Hamm, Lowdell, Morgan Storkey, 2000). Prevalence of health related behaviours such as diabetes or cardiovascular disease to mention a few can be distinctively different for different ethnic groups, which indicates an association between ethnicity and health. However, Karlsen, (2004) posits that indicators or factors employed to investigate the relationship between ethnicity and health are likely to fail accounting for the central facets of ethnic minorities’ experiences which could influence health, especially the impact of socio-economic disadvantage, housing, poor health services, harassment and discrimination. As already mentioned above factors such as discrimination, socioeconomic, housing, education and the accessibility of health services have a direct impact and possible relationship between health and ethnicity. In the UK alone, research indicates that at least one in eight from the ethnic minority group experiences some form of racial harassment each year. While two fifths believe that half of the British employers would decline to offer someone a job on the basis of their ethnicity. Ethnic minorities have been shown to experience repeated health and socioeconomic disadvantages than the majority ethnic group. This has a direct impact on the mental health of ethnic minority individuals who experiences such. In a study using data from the Health survey for England, (1999) plus a follow up study, the Ethnic Minority Psychiatric Illness Rates in the Community (EMPIRIC) to explore relationships between interpersonal racism experienced, discrimination as perceived in wider society, occupational class and various indicators of physical and mental health for the diverse ethnic groups in England including minority and majority white groups. The results indicated that there were significant independe nt relationships found between each of the factors explored and health. Hence, from these results current assessments were urged to take into account the different forms of structural disadvantages experienced by ethnic minorities and the diverse ways in which racial expressions can impact on health (Kalsen, 2004). However, there are a number of important but varied factors bearing on the health of ethnic groups and the overall population, which Stubbs (1993) argued that to understand these health patterns of ethnic groups there has to be a comparison with the host   group (majority ethnic group).   For instance, demographic, housing, lifestyle, socioeconomic and health service factors have a direct impact on the health of individuals (Baggott, 2004). Bannister (1901 as cited in Haralambos Holborn, 2000) argued that an individual’s ethnic background contributes to whether or not they are at a decreased or increased risk of developing a certain disease (s). For instance, he was very critical of Jews and their lifestyle describing them as ‘‘Yiddish money pigs’’ who did not like taking baths hence, were prone to blood and skin diseases. Conversely, it is opined that Bannister in this instance was expressing his hostile feelings towards this particular ethnic m inority group instead of advancing an evidence based argument for the association(s) of certain diseases and ethnicity. African-Caribbean and South Asians are more prone to developing diabetes than white Europeans. However, African-Caribbeans are far less likely to suffer from coronary heart disease than white Europeans which is more prevalent within the South Asians (Harding Maxwell, 1997; Nazroo, 1998). Suffice to say access to high quality health services is vital in sustaining a state of total physical, mental and social well being. According to Bunker, Frazier, and Mosteller (1994 as cited in Baggott, 2004), preventative measures such as screening, immunisation and medicine add at least 18-19 months to an individual’s life expectancy. A similar effect is also found when curative medicines are taken increasing the life expectancy by between 44-45 months. Generally this has not really happened with the ethnic groups as there are factors like discrimination and language barriers that impinge on the accessibility of health care. The social context in which ethnic minorities live and experience presents various challenges and disadvantages that will directly impact on their health negatively (Giddens, 2009). Pickett and Wilkinson (2008), argued that one’s health could be determined by the neighbourhood in which one lives, for example if a minority low status individual l ives in a higher quotient vicinity of their own racial or ethnic group then their health is likely to be better than those that live in lower quotient vicinities, this is referred to as the ‘group density effect’. Conversely, Smaje (1995) posits that concentration of ethnic minorities into poor vicinities has an independent and direct bearing on their health. Social structures for ethnic patterning in health show that African-Caribbean and Asians are more disadvantaged (Baggott, 2004). Harding and Maxwell’s (1997) study of the health of ethnics suggested that Indian, Pakistani and Bangladesh have a particularly high rate of diabetes and ischemic heart disease in comparison to other ethnic groups. This could be attributed to poor or overcrowded housing facilities amongst other factors already mentioned briefly above. Nazroo, (1998) from the findings of his study on the health of ethnic minorities agrees that Pakistani and Bangladeshi ethnic minorities experience high morbidity in comparison to other ethnic minority groups. He also found out that African Caribbean men had a lower mortality rate due to coronary heart disease, but were more prone to dying of a stroke compared to their counterparts including the majority ethnic group population. African-Caribbean and Asians ethnic groups do tend to record higher rates of hypertension, d iabetes and are three times more liable to having renal replacement therapy compared to the ethnic majority population (Raleigh, 1997). The health of ethnic minorities as mentioned above can be negatively affected by socioeconomic factors such as, employment and employment conditions. The majority of ethnic minority groups work in hazardous occupations, receive poor remuneration with diminished prospects for career progression. Their employment relationships are akin to the bourgeoisie and proletariat relationship. Bartley, Lynch, Sacker and Dodgeon (1998) suggest that the above findings of poor employment conditions and remuneration highlight the relationship between work conditions and high morbidity and mortality in ethnic minorities. Conversely, unemployment has an association poor health in that it cultivates financial hardship, stress, poor diet and living conditions. Factors such as socioeconomic disadvantages, poor housing, discrimination and poor health services create a knock on effect in one’s life cycle, ultimately exposing individuals to a host of disease and illnesses through a lack of equal opportunities. This leads to, anxiety, hypertension, depression and social isolation loss of one’s self esteem and purpose in life, which may result in the development of physical and mental health problems (Bartley, 1994 as cited in Naidoo Willis, 2000). However, Hull (1979) suggested that there is a correlation between migration and health. He attributed this to factors such as nature of symptoms and language barrier hindering ethnic minorities from accessing the right treatments because of the existing contextual cultural differences. Furnham and Bochner (1986) argue that if the host group does not offer any social support, and discrimination is displayed within vital institutions such as work environment, health, judiciary, and welfare. It creates more social stress resulting in mental illnesses for the migrating ethnic minorities. In addition Smaje (1995) links discrimination stressors to the psychological well-being as he suggests that racism has a bearing on differences in health between minority ethnic groups and the majority ethnic population. According to Pilgrim and Rogers (1999) black ethnic minority groups have a relatively short life expectancy and often have the worst health amongst ethnic minorities. In addition to that they posit that black ethnic minorities who experience mental health issues are likely to be discriminated against, often being depicted as an added threat or risk compared to the majority ethnic group. The Ethnicity and Health Report (2007) suggested that ethnic minorities have a higher probability rate of being confined in psychiatry through the criminal justice system unlike through diagnosis from the health system compared to the host group, especially Afro-Caribbean and Black Africans. Giddens (2009) supports the above statement by positing that indeed ethnic minorities mostly afro-Caribbean and black Africans are more likely to be stopped by law enforcers than their white counterparts. This form of institutionalised racism by law enforcement agents and the whole criminal justice system has sign ificant negative effects on minority groups’ psychological well being. Smith, Kelly and Nazroo, (2008) posited that racial discrimination, socioeconomic factors and policies that do not allow for equal opportunities and generally improve their existence within a host group could lead to a lasting effect on their mental and emotional health. In addition, injustice within the vital systems that provide help, health, work, and education further corrode ethnic minorities’ dilemma in terms of their physical and mental health (Smaje 1995). Evidence provided from the Ethnicity and Health Report, (2007) indicating the disparities in mental health between ethnic minorities and the host group is to some extent contentious, given that a cosmic amount of data employed is based on treatment rates. Consequently, this research indicated that ethnic minorities, particularly Afro-Caribbean people have higher rates of psychosis which is seven times more compared to the host group. Kalsen, Nazroo, Mckenzie, Bhui Weich (2005) from their research in the UK, on racism and mental health in ethnic minorities found that there was a significant relationship between racial discrimination and psychological well being. Indication from the results suggested there was a recurrence rate of psychosis annually of six per thousand for Bangladeshi people, ten per thousand for Indians, thirteen per thousand for Pakistani people, while they was sixteen per thousand for Afro-Caribbean people (Nazroo King, 2002 as cited in Kalsen et al., 2005). Nazro o (1998) from his studies posits that ethnic minorities’ mental health is worse than that of the host group. His findings were based on comparisons of the rates of reported suicide and para-suicide cases. Furthermore, Afro-Caribbeans are much more likely to be diagnosed as schizophrenics than their white counterparts (Smarje, 1995). Evidence reviewed in this essay has shown that there is a relationship between ethnicity and health (Kalsen, 2004). However, some of the evidence is contentious in that treatment rates were used to make a general assumption on ethnic minorities’ health (Ethnicity and Health Report, 2007). Evidence also suggests that indicators such as low-economic statuses, migration, and discrimination, poor access to health services, local area deprivation and high unemployment have a direct bearing on ethnic minorities and their health. It could be argued that the determinants of health vary between ethnic groups as a result of differences in genetic and socioeconomic factors which cannot be generalised across all ethnic groups. The evidence reviewed demonstrates differences in health across ethnic groups. These findings are important indicators of the need for investment programmes that are specifically targeted at improving the quality and quantity of health and other related services for ethnic minority groups. Future policies need to move away from a capitalist approach were ethnic minorities are exploited for their services with little reward and improvement of their social being. There should be a balance of socio-economic factors in-order to stimulate change and shape policies that improve accessing of quality health and related services such as education. They are fundamental to the health of both ethnic minorities and ethnic majority in modern day Britain. References Baggot, R., (2004). (3rd ed). Health and Health care in Britain.

The American civil war. Arms and Equipment of the Civil War Essay

The American civil war. Arms and Equipment of the Civil War - Essay Example Lee who served as the confederate commander surrendered. In western civilizations, wars, such as the American Civil War, are usually characterized by five essential features. These include: Technology The Armed Forces of the West have always relied on superior technology, usually to compensate for inferior numbers. In the American Civil war, there were technologies that made this conflict more lethal than other past wars that had been conducted in the United States. This was the last war in which ancient artifacts such as wooden ships were used during hostilities. It also saw the introduction of weapons such as torpedoes, Gatling Guns, ironclads, and submarines, into modern warfare. When the war first broke out, the soldiers from both the Union and Confederate sides used old smoothbore muskets.1 These weapons allowed only for slow reloading and had a firing range of approximately eighty yards. Soon the Union soldiers were outfitted with rifles, which allowed for quick reloading of bu llets and had better accuracy and a wider firing range. The Confederate army would also start utilizing these types of rifles for more effectiveness. Both armies also began to make use of a new bullet known as the ‘Minnie ball’. The Minnie ball was much easier to reload than the older bullets. While these new types of weapons were more efficient, they also caused many more casualties within a shorter time period. Minnie balls resulted in many soldiers who were not effectively killed by this contraption sustaining deep tissue damage. Unfortunately, the surgeons did not know how to effectively combat such wounds and would often cut off limbs of the affected patient in order to save his life. Another weapon that gained widespread use during the civil war is the Gatling gun- which was essentially a machine gun that was positioned on wheels. This weapon could kills tens of men while being fired and rotated to cover all sides. Discipline More in the Western civilization relie d heavily on discipline, Western military practice has always exulted discipline, rather than kinship, religion or patriotism as the primary instrument that turns bands of men as individuals into soldiers fighting as part of an organized unit.2 In the American civil war, the soldiers had to live in a structured society which had privates at the lowest rank, followed by corporals and then sergeants, second lieutenants, lieutenants, captains, majors, lieutenant colonels, and finally colonels. To keep the men in top fighting condition, there was strict discipline. Offenses as minor as disregarding camp duty and not taking good care of one’s rifle was punished by hard labor such as digging latrines and uprooting large trees. More serious offenses such as theft, insubordination, or even cowardice in the time of action were punished by forcing the errant soldier to perform activities that would humiliate them before their colleagues. For instance, men were forced to carry logs, or wear signs that proclaimed their mistakes to all. There were also offenses such as performing acts of treason, murder, and desertion for which the errant soldier would be killed by hanging or by a firing squad. These punishments would be administered by the army’s Provost Marshal. Aggressive Military Tradition Shared military theories and doctrines help soldiers to understand how to conduct major operations as well as campaigns while preparing them for service in the fields. In the American civil war, the armies utilized Jomini's war theories. Baron Jomini’s theory on war was based on major European wars such as took place in the

Global Change threatens the liberal order Assignment

Global Change threatens the liberal order - Assignment Example The world economy has been working in quite a complex way in the past decade. The critical role has been played by the global financial crisis and breakdown of the American rule and power (Groody, 2002). The paper is an analysis of present situation of the international liberal order and trends that have threatened its presence in the current context. The paper also analyses an antithesis that supports the previous order and concludes on a choice between the two opinions. Liberal order in the context of liberal internationalism assumes that governments and people have a shared common interest towards establishment of the global cooperative world, despite the existence of restrains, sovereign equality and reciprocation. The optimist view for international liberal order goes forth to discuss that all states have the ability to overcome constraints with a view to cooperate, thereby resolving security issues, working towards collective action and consequently, developing a stable and open system (Steins, 2004). United States of America was deemed to be the champion of international liberal order until the twentieth century. The sponsor, function and role of United States have undergone a major change over the recent years. Facts such as, those pertaining to geo-political position of the United States, have been responsible for shaping up America’s liberal order, but more important aspects are the logic and character of this very liberal order placed within the global context. The political system of the western world, including currency, technology, alliances and markets, has been fused with the liberal order for providing a base for liberal internationalisation. During the Cold War, the United States developed towards becoming operator of the global capitalist form of liberal political order (Ikenberry, 2011). With closure of the Cold War, peaceful terms that emerged were more in

Quality of service of a network

Quality of service of a network CONGESTION MANAGMENT: Networks which are designed to support most different traffic types which share a single data path between routers. Congestion management techniques should be considered in such cases to ensure the quality and treatment for the various traffic types. Traffic prioritization especially important for delay-sensitive, interactive transaction based application for instance, for example takes video conferencing that requires higher priority than the file transfer applications. However use of WFQ (weighted fair queuing) ensures that all traffic is treated fairly. Prioritization is most effective in WAN links where the combination of bursty traffic and relatively lower data rates can cause temporary congestion if there is no congestion on the WAN link, there is no reason to implement traffic prioritization. APPLICATION QUALITY: By various parameters used for network quality of service which allows the specification of quality metrics. Such quality of service metrics are monitored and analysed using network quality parameters and important aspect of quality which is always ignored in many cases and overlooked is the behaviour of each and every individual applications in the internet recognised .most applications try to possess a majority part of network resources possible, immediately it may not or influence the quality of an application. NETWORK QUALITY OF SERVICE: The Ability to provide better service to a selected traffic.Quality of service refers to the ability of a network to provide highest quality service to any selected network traffic using various technologies in the latest networks used with a combination of traffic Qos ensures the exact application to be accessed to the resources of the network first, it is a combination of various technologies which allows application to recive request most acceptable and predicted service levels in terms of data and its Bandwidth (throughput capacity) latency variation in jitter, packet loss and delays.Qos provide the best features and more predictable network service by following methods(cisco 2009) Ø Dedicated bandwidth and support Ø Loss characteristics Ø Congestion avoidance and mangment of network Ø Network traffic shaping OPERATION OF QOS: Ø Qos distinguishes the traffic and splits it with very exact timing requirements Ø It improves resources in the network so that all the traffic reaches the specified destinations reliably and faster Ø It doesnt create any bandwidth it simply manages it effectively to meet the application requirements (OPNET 2008) Here the working of qos follow a series flow of simple rules in order to execute the file or a packet and at first the packet is pass through the classification which means that the following packet must be in which group does it fit then the packet is moved on to the next level which is the pre-queuing which means that the following packet is arranged in a order according to the source and the destination numbers and then it is again moved on to the next level which is the queuing and scheduling its main work is to set the stream to the destination point so that it automatically enforces the bandwidth allocations then moves on to the last level which is the post queuing which increases throughput on the lower speed links so that it reaches the destination point within the time it has decided and thus the working of the qos is completed. ADVANTAGES OF QOS: Ø Dedicated bandwidth Ø Controlled network latency and jitter Ø Improved loss characterstics Ø Control and predictability beyond best effort concept (OPNET NETWORK 2008) NEED OF QOS IN A NETWORK: All packets in a network are given equal access to all the resources , the priorty acn only be given when we can distinguish data packet from a voice packet. For a company network to effectively use the network and its resources it must identify which network traffic is the appropriate and which is not to allocate the right recourses to effectively support the traffic streams . The priority should be given to all the data streams to failing to do so can create low quality of voice and data, because most of the audio and visual application is delay and jitter sensitive. Only a good Qos can give the audio and video packets the best priority access. Qos evolution: The networks which are used with Qos enabled are called the Best -effort network. Where each and every packet is treated in the same way which is significantly important in the network design for preferable results, when even space in the cpu is available these type of networks work prominently. There are two major architectures of qos, both the architecture have different approach and different ways of quality of service in their own preferable ways. The main architecture of Qos is integrated services and differentiated services. Traffic characteristics that Qos tools can effect 1) Bandwidth 2) latency 3) jitter 4) compression 5) queuing BANDWIDTH: Bandwidth refers to number of bits per second that can reasonably be expected to be successfully delivered across same medium. firstly bandwidth techniques are mainly used to describe or define network traffic and to do this we can set some special type of techniques which are mainly used by the network devices such as blue coat for instance and by using this we can setup a type of service (TOS) in the packet of the internet protocol header and by using the required information of the type of service we can set the device in action and allow the traffic to flow in different direction and for another instance we can choose some factors to involve this issue such as audio clarity, if the sound is audible in two different direction then it is said to be working in perfect condition and this can be measured by the MOS (which means the mean opinion score) , so by this we can rate from 1-5 which means that 1 scores the worst and 5 scores the best and the average typical analogue call whi ch rates from 4.1 to 4.7 and a avg cell phone ranges from 3.5 to 3.9 and if we considered the VOIP CALLS ranges from the 4.0 to 4.4 so which means that the VoIP also has the best average rating in audio clarity and if we comes to reliability comes to 99.999 so which is more reliability to the customers and the usage of them is also more and the techniques used in this kind of symphony which is sophisticated and the consistency is also more which is mixed out with the qos so this is in short all about bandwidth in qos LATENCY: It is mainly specified as some serious problem to qos which is also known as the delay and if we speak in technical words its the same amount of time taken by a packet from source to destination and if the latency and the bandwidth are defined they are for speeding the network so for instance we can say that a normal average person can hear a call upto 250 ms approx and 200 ms in sensitive person ear so if the call doesnt return in that range the caller is going to be disappointed. JITTER: It also refers to the same problem but for connectionless or wireless so which is also called as a delay which must be a serious and most inappropriate but business customers such as for company which is dealing with important calls so in this here if we see the database server is connected to some system and the employees are storing some information to the database systems and in between there are calls to handled and the calls doesnt seems to go through the cloud of the similar database server so we can find the disturbance which are caused by the latency and jitter so in order to watch and control the traffic we must maintain the jitter in control and the specification for this is it must be less than 100 ms for the communication less than 100 ms for normal database because if the jitter took place a bit slow in voice band it doesnt have a problem but if it takes under the packet series then it might be some kind of serious issue so in order to reduce this we must all keep the j itter in control. bandwidth refers to number of bits per second that can reasonably be expected to be successfully delivered across same medium Compression: Either the payloads or the headers compressed by reducing the total number of bits required to transmit the data. Call Admission control: reduces all the overall load of the network by denying any new incoming voice and video calls. Queuing: Qos refers to a broad collection networking technologies and techniques. The goal of Qos is to provide guarantee on the ability of a network to deliver predictable results. Qos involves prioritization of a network, Qos is a method to guarantee the bandwidth relationship between individual or application or protocols. Qos refers to the capability of a network to provide a better service to selected network traffic over various underlying technologies including frame relay,(Cisco systems Inc. 1999). There are seven Qos mechanisms and tools that are used to implement Qos in a computer network. Ø Congestion management Ø Congestion avoidance Ø Control admission control Ø Shaping and policing Ø Bandwidth reservation Ø Link efficiency Ø Classification and marking 1.1.3 Aim of Qos is to provide a dedicated bandwidth sufficient to deliver for the service of the applications by controlling latency and jitter, and by reducing data loss. Network characteristics managed by quality of service. Category of quality of service mechanisms: 1) Admission control 2) Traffic control 1.2.1 Admission control: Gives the information of number of users and the applications used to network resources it allows only specific users and resources which can be used in a network segment (subnet). 1.2.2 Traffic control: It controls and regulates the data flow by classifying and marking the packets based on priority and by stopping traffic, service class assigned to a traffic flow which evaluates the quality of service treatment, the traffic receives. 1.2.3 Call admission control: It provides the overall quality for all the networks, it controls the voice disturbance from the voice traffic, and video from the other video traffic 1.3.2 Classification and marking: For defining a quality of service identifying the traffic is the first case involved in the procedure which is treated either differently or preferentially which is done by classification and marking. 1.3.3 Bandwidth reservation: Bandwidth reservation provides guarantee to the bandwidth, i.e., bandwidth is provided whenever needed without reserving it for a specific application or flow in a network. 1.3.4 Shaping and policing: The significant issues related to quality of service in a network are solved by traffic shaping , the delay and loss in a network are solved by traffic shaping which is called as(egress blocking)The data which is sent or received are measured by traffic shaping and traffic policing . traffic policing in a network is used to remove all the excess packets which helps to overcome the policed rate. The excess packets are again en-queued by shaping. Both shaping and policing prevent the traffic from exceeding the bit rate defined. Link efficiency: Link efficiency is used increase the quality of service of a network,particularly if the given note continuously increase the bandwidth rate on a network which causes the sudden change in behaviour of the network. Which slows down data applications significantly.if the load exceeds the given bandwidth for a period of time the application slows down completely or even stops down ata particular point because of the continuous queues which can be avoided by using the link efficiency. 1.3.6 Congestion management: Whenever queuing occurs in a network congestion management gives the ability to rearrange the packets. 1.3.7 Congestion avoidance: Congestion avoidance tools are used to avoid congestion. It enables queue to avoid congestion. Whenever the rate of transmission load and offer load exceeds the line rate send by various senders.Queues are formed which may cause congestion. The queue are managed by congestion avoidance tool by dropping the packets randomly which are selective which reduces the congestion level. WHY DO WE NEED QOS Each and every packet will be given equal access to resources when we not consider the QoS policies. We cannot give voice priority if we cannot tell a voice packet from a data packet. In order to utilize its network resources efficiently for a company, so to support those traffic streams it must identify which network traffic is critical traffic and allocate appropriate resources to support those traffic streams. Otherwise, the result could be intermittent with voice quality complaints. Applications like voice and video are delay and jitter sensitive. Voice packet will be given first priority access to the interface queue, when we use a good QoS policy. For example, both FTP and an voice packet arrive at the same time at an outbound router interface. When we not consider the QoS policies the voice packet may need to wait in the queue until the FTP packet has been processed out the interface. This may results delay of unacceptable amount of delay into the voice path which will depends upon the interface speed. Traffic flow with out qos (global knowledge,whitepapers,[2],author:gardiner2008) The voice packet could be given priority first over the FTP packet when we use QoS configuration. The FTP packet may be fragmented to make sure that the voice packet does not show any excessive delay, if the interface speed is less than T. QoS Evolution The main reason for the wide transformation of best-effort models to more complex differentiated services models is by privately owned enterprise and service providers networks, the meaning that the network gives different applications differing levels of service. 2.6.1 Congestion Management (Queuing): QoS queuing tools provide you with a variety of queuing methods. Queuing tools define a number of queues. The queuing tools are as follows: a. Priority Queuing(PQ) b. Custom Queuing(CQ) c. Weighted Fair Queuing(WFQ) d. Class-Based Weighted Fair Queing(CBWFQ) e. Low Latency Queuing(LLQ) f. Modified Deficit Round-Robin(MDRR) a. Priority Queuing: Priority Queuings most distinctive feature is its scheduler. PQ schedules traffic such that the higher-priority queues always get serviced, with the side affect of starving the lower-priority queues. With a maximum of four queues, called High, Normal, and Low, the complete logic of the scheduler can be easily represented, as shown in figure. (Cisco systems, 1999) b. Custom Queuing: As with most queuing tools, the most interesting part of the tool is the scheduler. The CQ scheduler reserves an approximate percentage of overall link bandwidth to each queue. CQ approximates the bandwidth percentages, as opposed to meeting an exact percentage, due to the simple operation of the CQ scheduler. The CQ scheduler performs round-robin service on each queue, beginning with queue 1. CQ takes packets from the queue, until the total byte count specified for the queue has been met or exceeded. After the queue has been serviced for that many bytes, or the queue does not have any more packets, CQ moves on to the next queue, and repeats the process. (Morgan, 1991) c. Weighted Fair Queuing: Weighted Fair Queuing differs from PQ and CQ in several significant ways. The first and most obvious difference is that WFQ does not allow classification options to be configured. WFQ classifies packets based on flows. A flow consists of all packets that have the same source and destination IP address, and the same source and destination port numbers. So, no explicit matching is configured. The other large difference between WFQ versus PQ and CQ is the scheduler, which simply favors low-volume, higher-precedence flows over large-volume, lower-precedence flows. Also because WFQ is flow based, and each flow uses a different queue, the number of queues become rather large up to a maximum of 4096 queues per interface. And although WFQ uses tail drop, it really uses a slightly modified tail-drop scheme- yet another difference. (Cisco systems Inc, 1999) d. Class-Based WFQ: CBWFQ is most like CQ, in that it can be used to reserve minimum bandwidth for each queue. It does differ from CQ in that you can configure the actual percentage of traffic, rather than a byte count. CBWFQ is like WFQ in that CBWFQ can actually use WFQ inside one particular queue, but it differs from WFQ in that it does not keep up with flows for all the traffic. e. Low Latency Queuing (LLQ): LLQ combines the bandwidth reservation feature of CBWFQ with a PQ-like high priority queue, called as Low Latency Queue, which allows delay-sensitive traffic to spend little time in the queue. But first, this section begins with WFQ, which uses a completely different scheduler. Table 2: Comparison of Queuing Tools. (Odom W, et al, 2005) Tool Maximum Number of Queues Classification Capabilities Queue Service Algorithm/ End Result of Algorithm PriorityQueuing (PQ) 4 IP ACL Input interface Fragments Strict service; always serves higher-priority queue over lower queue. Custom Queuing (CQ) 16 IP ACL Input interface Fragments Serves a configured number of bytes per queue, per round-robin pass through the queues. Result: Rough percentage of the bandwidth given to each queue under load. Weighted Fair Queuing (WFQ) 4096 Automatic, based on flows, (Flow identified by source/destination address and port numbers, plus protocol type.) Each flow uses a different queue, Queues with lower volume and higher IP precedence get more service; high volume, low precedence flows get less service. Class-Based Weighted Fair Queuing (CBWFQ) 64 IP ACL NBAR Same as CB marking Service algorithm not published; results in set percentage bandwidth for each queue under load. Low Latency Queuing (LLQ) N/A Same as CBWFQ LLQ is a variant of CBWFQ, which makes some queues priority queues, always getting served next if a packet is waiting in that queue. It also polices traffic. Modified Deficit Round-Robin (MDRR) 8 IP precedence Similar to CQ, but each queue gets an exact percentage of bandwidth. Supports LLQ mechanism as well.
