Describe The Mandatory Rotation Of Audit Firm Accounting Essay

Describe The Mandatory Rotation Of Audit Firm Accounting Essay Introduction From the 2008 financial crisis, the weakness of audit system has exposed in several aspect. European Parliament and public consider that the auditors fail to play during the financial crisis. The European Commission said that the auditors only consider majority of banks had exposed a great quantity of loss from 2007 to 2009 in both on and off balance sheet in the financial crisis, however, it is a hard work for the public and stakeholders to know how the auditors to give the clean auditing reports to their principal. In addition, the European Commission takes into account preventing the concentration in the audit industry, which including restricting the choices and competition. Further, they also consider the independence of the audit firm and the reduction of the expectation gap. All things the European Commission do is to increase the quality of audit, so they think that the current auditing system should be reform. According to KPMG (2012), because of the failure of auditors in financial crisis, the lobby of small firms and the US has taken action on the independent issue. Meanwhile, in order to adapt to the environments, which contain changes to financial reporting and increasing the risk and going concern issue for the companies. The European Commission came up the proposals on 30th November 2011 to address the matters that appeal in the financial crisis and rebuild the confidence of the audit system. The proposals define the role of auditors and propose more restrict provisions for audit firms. It aim at strengthening the independence and professional skepticism of auditors, making the audit industry more diversification, enforcing the regulation, promote the cross-border stipulation of audit services and relieving the burden of the small and medium-size enterprise. To enhance the independence of audit firm and prevent the concentration of the audit industry is the main purpose of the propos als. The Elliott and Jacobson (1998) suggested that audit independence is an absence of interests that create an unacceptable risk of material bias with respect to the reliability of financial statements. The basic goal of audit is to assure the information which provide to shareholders are reliable. Further, as for audit independence, the direct role is to provide auditing serve and make the cost of capital market more efficiently. Consider about preventing the concentration, should make the audit industry more dynamic, such as decreasing the power of the Big Four audit firm (KPMG, Deloitte, Pricewaterhousecoopers and Ernst Young). In addition, the dynamic of audit market give the opportunities for small and medium-size enterprise to benefit from the internal market. In order to strengthen the independence of audit and make the audit market more dynamic, the European Commission brought up the proposals to perfect the audit system, the key elements of the proposals is mandatory rotation of audit firms, mandatory tendering, non-audit services, and European supervision of the audit sector, Enabling auditors to exercise their profession across Europe, Cutting red tape for smaller auditors. This essay is aim at discussing the issue of mandatory rotation of audit firm, one of the key elements to enhance the independence of audit industry. The essay will divided into three parts, firstly, it will describe the mandatory rotation of audit firms; secondly, it will analyses the argument for and against this issue; finally, it will come to a conclusion. Describe the mandatory rotation of audit firm In order to strengthen the auditor independence, the European Commission is considering introducing mandatory external rotation. In the previous years, only internal rotation is required, which means only auditors should be rotated, because they think that auditors may make less suggestions because the routine activities of audit. However, the internal rotation cannot enhance the independence of the auditors, because the audit firm and audited entity build up partnership, no matter which auditors engage in the audit procedure, they have closely relationship, the independence of auditors cannot be enhanced. Therefore, current environment has suggest that the internal rotation is not sufficient, the external rotation should be taken in account to achieve the independence of audit. The proposal required the audit firm should be rotated after at most six years (with some exception). In addition, it should be after at least four year before the same audit firm can be entrusted again by the client, this is stated as the cooling period. The cooling period ensure the mandatory rotation can be implemented effectively, because if there is not the cooling period, the client can entrust the same audit firm after a short time, so that the closely relationship cannot be avoidance. There is a exception that the period of rotation can be extend to nine years if joint audits are engaged. This means that if an audited entity entrust at least two audit firm, it can extent the period of rotation to nine years, because the joint audit can make each audit firm work harder to avoid another audit firm find out their failure, this can increase the quality of the audit, so called four-eye principle. Hence, the joint audit is encouraged. According to Bocconi, which do a survey of the effect of mandatory rotation in Italy. The investigate shows that 69 % of managers of listed companies approve of rotation. 14 % consider it negatively. The survey presents a positive result, because they consider that in previous years, auditors focus on routine activities rather than making improvement. The people including in the survey agree the mandatory rotation in Italy can strengthen the independence. Discussion of the mandatory rotation The argument for the mandatory rotation of audit firm Firstly, the mandatory rotation of audit firm can reduce the risk of familiarity threat. If there is not mandatory rotation, the audit firm may have closely relationship with the audited entity, which would lead to several problems. For instance, the proposal (2011) of the European commission suggests that the audit firm tend to know well about the management of the audited entity, so that they may think the audit work as a routine work, which just repeating the work annually, and they pay less attention to make an improvement and find out the mistake the audited entity made. In addition, the auditor may be less suspicious of the audited entity, instead, they may decrease the difficulties so as to maintain the good relationship with the partner. The long period of engagement will cause routine, which may affect the competence and the quality of audit, hence, the mandatory rotation is necessary for reducing the familiarity threat. Secondly, according to Hoyle (1978), short term engagement will encourage the auditors to do better. If the audit firm fails to make the improvement in their auditing period, however, the next audit firm detects the unreported information, the reputation of the previous audit firm may be affected, so that the auditor will minimize the errors for managing the reputation. Further, the mandatory rotation can avoid the mistake or unreported information continue, because the next audit firm will scrutinize the document provide by the former audit form. Also, the long term engagement of the same auditor may cause the auditor trust the previous auditing procedure, so the rotation can reduce the risk of the auditor regards the engagement as the repetition of the last years work. Therefore, the mandatory can improve the quality of audit. Thirdly, the rotation provide the small and medium-size entities good opportunity to enter the competition in the segment of market. Although, the Bocconi study (2002) showed that the mandatory rotation did not provide the small and medium-size entity opportunity to compete in the audit market, they cannot compete against the large audit firm for the public-interest entities. However, take the mandatory tendering into account, the situation can be changed, the rules allow the small and medium-size entity to bid in the tendering, so that the rotation and joint audit enlarge the choice of audit firm for the audited enterprise. Therefore, combined with the mandatory tendering, the mandatory rotation can encourage the competition of the audit firm and provide more opportunity for small and medium-size entity to enter the audit market. Last but not least, the rotation can reduce the risk of fraud, which the audited entity collude with the audit firm. If both of the audited entity and audit firm fraud the public, when rotation implement, the fraud will be exposed by the coming new audit firm. The scandal of Enron can give a good example of this, if the rotation enact, the deceptive accounting may be found early or the audit firm will not collude with Enron in order to prevent the impairment of the reputation. So the mandatory rotation can reduce the risk of fraud. The argument against the mandatory rotation of audit firm According to the Bocconi study (2002), the opinion the audit firms and managers argue is that the cost of auditing fees as well as man-hours will increase under the mandatory rotation. It takes time for the incoming audit firm to read the sufficient document to know the audited entitys business. If the incoming audit firm do not know the audited entity enough, the quality of audit will decrease. Further, because there are many kinds of industry, it is difficult to maintain the industry specialization and may cause lack of choice of audited entity. According to Chi et al. (2004), they do not agree the mandatory rotation, they hold the opinion that the rotation may have negative impact on the quality of audit. They show the explanation that in the last year of audit before the rotation, the auditors may abandon their independence because they do not need to worry about the loss of quasi rents for they will not be re-elected. These can lead to the decrease of the last periods auditing quality. Bigus and Zimmermann (2007) said that because of the rotation, the quasi rent had been decreased, which implies the rotation may not increase the independence of audit firm. Consequently, the mandatory rotation cannot increase the quality and independence of audit firm as expect. Conclusion When come up the new proposals, there will have different voice because of the different role they play. As for the rule of the mandatory rotation of audit firm, according to the European Commission, the Big Four hold the opposed attitude, they insist there is studies that have certify the mandatory rotation affect the quality of audit firm; the Mid Tier Firms and small and medium-size entities also do not stand by the rule, they consider the increase cost and harm to the quality of audit firm; the investors had divergent opinion; some of public authorities did not favor of the mandatory rotation, while others think the rule will be beneficial, one of the idea regards to the issue they came up it to allow the committee to decide whether the rotation of a firm should be needed. To sum up, the new rule of the mandatory rotation of audit firm may be beneficial, but only under certain situation. For example, the cost of fees and man-hours can be low to change audit firm; the negative impact of last period of audit before rotation can be avoid. So that, the proposal can be beneficial if more detail and rules can be add in to make the mandatory rotation more perfection.

How did the Dada Artists Challenge the Contemporary Art?

How did the Dada Artists Challenge the Contemporary Art? This essay will dive into the world of dada by firstly exploring the movement with an in-depth look into the brief history of dada and the foundations of which it was built around, how it changed art Dada was not just an art movement but as much of an cultural movement, this revolutionary movement originated in Zurich, Switzerland in the early months of 1916 it was one of the shortest lived art movements and only survived less than 10years until 1924 Dadaism did not start off as an art movement it was born of more as a artistic protest that grew as a response to not only the carnage that was world war one but also to the destruction of society that was crumbling around them, as the war spiralled across Europe the majority of the artists who founded dada had witnessed the relentless slaughter of innocent men, women and children as undeniable proof that the nationalist authorities had failed society and was undeniably corrupt. With most of the Dadaists being directly affected by WW1 and fleeing from across Europe themselves to seek refuge in Switzerland as many people did with Switzerland being neutral within the wall it became a safe haven for a huge number of people including many artists and intellects who found sanctuary in Zurich, which was the birthplace of dada included in the refuges that escaped the destruction of the war where a young couple from Munich, Germany named Hugo Ball who was a former theatre director and his gi rlfriend Emily Hennings a dancer who also wrote her own poems and books not long after arriving they became the parents of dada when they convinced the owner of a nearby cafà © to let them rent a room from him to begin a cabaret club. They named their club Cabaret Voltaire (fig .1) after one of Frances greatest entitlement writers Francois- Marie Arount and commonly known as Voltaire he was a famous writer, historian, poet and philosopher but was most famous for his wit and his attacks on the roman catholic church with his advocacy of freedom of religion and speech you can see how the young couple related to his values and beliefs and used him as an advocate and inspiration in the laying of the foundations of dada. Cabaret Voltaire opened its doors February 5th 1916 with Hugo Ball sent out a press release that translated Cabaret Voltaire under this name a group of young artists and writers has formed with the objective of becoming a centre of artistic entertainment in principle, guest artist will come and give musical performances and readings at the daily meetings. Young artists of Zurich whatever their tendencies, are invited to come along with suggestions and contributions of all kinds and with this release the dada family was formed with a bunch of like-minded misfits who included Marcel Janco, Tristian Tarzara, Richard Huelsenbeck, Hans (jean) Arp, Sophie Taeuber, Kurt Schwitters, Marcel Duchamp and Joan Miro ( fig.2) all coming through the doors within the first couple nights of the club opening and they quickly bonded over not just society but art and they woes of the world surrounding them and how many in society did not know or care with the world surrounding them, this small group of people connected over art and the discretion of the world around it and became close friends spending most days and nights together discussing and practising their own politics, views and art. With the Cabaret Voltaire being run by this close group of friends it became a cross between a night club and arts centre while here artist could showcase their work in a whole new experimental environment, often playing around with music, dance, theatre, poetry, readings, photography and all photography and often experimenting with visual arts. while showcasing their art to the art society of Zurich they could discuss the world around them and the founders became united in their views and their protest the war, society and the establishment. Performances in the beginning were relatively conventional being true to a variety show but as WW1 grew so did the artists anger and wanting for change and realisation, part of the movement was a full-on strike on the art world which they saw as part of the system it was considered likewise accountable and therefore had to be overthrown. Dada questioned the value of all art and whether its existence was simply an indulgence of the middle and upper-class they confronted traditional artistic values with nonsensical and irrational attitudes and with these provoked conservative complacencies with outrageous statements and actions as within a couple of weeks the artists at Cabaret Voltaire were experimenting with shock tactics becoming increasingly unorthodox and rebellious with its art and as soon as the founders became aware that the crowds were drawn to this type of art and valued it they began to run with it they began to showcase their own politics and views and rebelled more and mor e against art, society and the war. Although the Dadaists were united in their ideals they had no unifying style, an between the short lived period of Dada group it attracted many different type of artists who were not willing to conform to societies standards of art which meant the artists could allow the movement to have so many diverse styles which allowed them to play with their art and grow with new styles and bring to life new art. The Cabaret Voltaire and its members pushed the boundaries that surrounded them in a very short lived time together at the Cabaret Voltaire as it was forced to closed their doors only six months after it opened due to the nightly antics of the huge crowds that were drawn to the club and the relaxed nature of the lease owners not paying rent. Marx and Mills Theories of Freedom: A Comparison Marx and Mills Theories of Freedom: A Comparison SANDRINE UWIMANA MARX AND MILL’S VIEWS ON FREEDOM. This essay compares and contrasts Karl Marx and J.S. Mill on their understandings of freedom and their analyses of the impediments to its realization. Both Marx and Mill agree that human beings are capable of making progress and that the concept of freedom is an end in itself. Thus, they saw freedom as a means to realise individual potential and self-determination. However, both differ on the concept of freedom realisation and the impediments to freedom. Mill argues that the impediment to freedom is the masculine society while Marx argues that the impediment to freedom is the bourgeoisie. Furthermore, the essay discusses the intervention by state/society into freedom. Mill assert that the society can interfere into someone’s freedom when there is harm done to others. For Mill freedom should be exercised as long as there is no harm done to others while Marx supports the freedom to overthrow the bourgeoisie . On the other hand, Marx views hold that the government/ society should intervene in individual freedom to avoid individuality that leads to private property and hence creating classes. Both Marx and Mill see freedom as an end in itself. According to Marx’s definition of freedom, was viewed as an end in itself. â€Å"Only in community has each individual the means of cultivating his gifts in all directions; only in the community, therefore, is personal freedom possible. In the previous substitutes for the community, in the State, etc. personal freedom has existed only for the individuals who developed within the relationships of the ruling class, and only insofar as they were individuals of this class,† Karl Marx and Frederick Engels. For Mill, freedom of speech, opinion and the right to associate with others, were important for the progress of mankind. Freedom of choice is and do what is desirable as long as no harm is done to others is an end in itself. As Mill thus say that , â€Å"†¦ though the customs be both good as customs†¦ yet to conform to custom†¦ does not†¦ develop†¦human faculties†¦exercised only in making a choice.† (Mill 60). It is evident that freedom of choice is important to the development of individuality and progress of the society as a whole. Thus, freedom is an end in itself, because utilizing human lead to make choices is beneficial for personal development. Hence, the view that sees freedom as an end in itself can be attributed to both Marx and Mill. On the other hand, there are considerable differences between Mill and Marx perspectives on views regarding freedom. For Mill, freedom is important for the purpose of searching for truth and for reasons to live and for progress ( Mill 29). Mill asserts that a man must be free to pursue his happiness and pleasure. Furthermore, Mill in â€Å"On Libertyâ€Å" asserts that individual freedom is the paramount chief for the progress of society. The opinion of the individual has to be nurtured and allowed to grow so that he can use his assets and talents to benefit the society at large ( Mill 63). Thus, Mill, can be summarised in On Liberty : The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. An individual has the capability and the power to be creative in a society that recognises that ability. As well, Mill argues for the freedom of speech for everyone and that each individual opinion should be respected regardless of its content. Mill also argues that freedom/liberty is important for the pursuit of happiness (Mill 29). However , Marx asserts that people should not be individualistic and should not pursue their own interests but should conform to the society’s norms. For example in â€Å"On The Jewish Question: Zur Judenfrage, â€Å" Marx criticizes the liberal concept of freedom and argues that it assumes that a human being is â€Å"an isolated monad† ( Max 364) who pursues his own private happiness and also tries to avoid conflict with others ( Marx 370). He argue that an individual cannot be treated separately from society. The individual is part and parcel of society and there is nowhere he/she is going to operate in isolation without affecting the society as a whole. Hence, Marx argues that the communist system would make it possible for everyone including children and women to be free as they would not be for ced to work for the anyone (Marx 72). For Marx, this is freedom. As well, Marx explains how â€Å"my free activity† transforms itself into â€Å"the alienated and inhumane power† with the fetishism of the commodity. (Marx, 554). Furthermore, Mill and Marx offer a different perspective on the intervention by state/society into freedom. Mill argues that there is no justification for interfering in other people’s opinions and thinking. Not even the government has the right to interfere in someone’s freedom. It could be argued that this is the foundation of modern individual freedom. You are free and entitled to your own opinions as long as you don’t harm another ( Mill 4). â€Å"The reason for not interfering, unless for the sake of others, with a persons voluntary acts, is consideration for his liberty. His voluntary choice is evidence that what he so chooses is desirable, or at least endurable, to him, and his good is on the whole best provided for him by allowing him to take his own means of pursuing it,† Mill (14). In contrast, Marx argues that there is a need for the state to interfere with private property so that property ownership might be abolished. The government should hav e the right and the means to control the people who have private property, thereby forming an ideal communist society. It has to be noted that Marx ‘s arguments were based on the view that capitalism was evil and hence needed to be replaced by communism. As well, Karl Marx, in On the Jewish Question says that None of the supposed rights of man go beyond the egoistic man, man as he is a member of civil society; that is, an individual separated from the community, withdrawn into himself, wholly preoccupied with his private interests and acting in accordance with his private caprice. Hence, a person has to conform to the society’s norms. Thus, Marx views counter-argue the view by Mill that the society should respect the individual freedom. On the other hand, Mill warns against the tranny of the majority because sometimes the majority’s opinion is not always right. Thus the protection of the individual is more important and have to be protected. In addition, Mill’s and Marx’ views differ on the exercise of freedom. According to Mill, freedom and liberty is having free will and self- determination without being subjected to invariable law ( Mill 32). Mill adds that innovation and creativity can be achieved in a free environment . Thus, he advocates for a free environment which allows for development and growth of new ideas. â€Å"Genius can only breathe freely in anatmosphereof freedom. Persons of genius are †¦moreindividual than any other people† ( Mill, 65). Thus, freedom of the individual will allow new ideas and result in the progress of the society as a whole. As well, he argues that the society or the state should not force people to conform to the particular norms of the society and nor intervene in the activities of the individual which contribute to the development of the community as a whole. However, Mill acknowledges that the only time when the government or the society has to interfere i s when it steps in to prevent your harming other people (Mill 68). Thus, Mill asserts that freedom should be exercised as long as there is no harm done to others. Mill, a man’s freedom has to be protected and allowed to be explored without infringing on other people’s freedom. Nevertheless, the exercising of freedom should be checked. In addition, Marx argues that the majority of the working class should fight for their freedom and overcome the tyranny of the bourgeoisie (Marx 73). This seems like the views of Mill who argues that the citizens are to have freedom and the state, which is in small minority, should not exercise tyranny over them. Mill, on the other hand, argues that the freedom to unite has to be done in such a way that there is not harm to others . Mill would see the argument of Marx advocating the overthrow and taking the property of the bourgeoisie as harm done to others. In the Manifesto, Marx calls for the freedom of the working class to unite and in the end to revolt against the production owners also known as Bourgeoisie (Marx Engels, 34). The working class will rise up for their freedom. Marx asserts that freedom can be achieved through ideology. If the working class would learn and know the ideology of the bourgeoisie, they would be able to develop a counter ideology and hence the proletari at would become self-conscious and self-aware and thus be able to manage and control the means of production (Marx 173.) Thus, Marx argues that the working class would be freed from alienated labour if they knew the ideology of the bourgeoisie. This is how the proletariat would be able to overcome the exploitation of the bourgeoisie. For Marx, the working class should be united and fight for their individual freedom . As well, according to Marx, freedom could be achieved if the working class owned the means of production. It can also be viewed that capitalist system dies freedom to the working class in the modern era. For example, even if you desire to have a certain type of work, you are not free to choose your boss. On the same point the people who controls the means of production have the freedom to choose among the abundance supply of labour. I would agree that communism in which the means of production is owned by many could have been a good society for mankind. Capitalism denies the freedom of choices to many people especially the poor. It lead to a few of individual controlling all the wealth. As well, I would argue that in the modern era, due to capitalism, most working class people do not have freedom. In the world of today, the owner of the means of production decides which work you are supposed to do but the working class person is not free to choose his work and set his own wages. This could be regarded as a lack of freedom as the working class do not have a choice but rather to work under the conditions set by the master. For Marx, the ideal society was communism that gave everyone a chance to own something and freedom to majority. As well, Marx argues that there is a need for society to interfere to help the individual realise his potential/ self-cultivation. This is so because Marx believes that the society should be classless. Marx asserts that classless society is the foundation of freedom for all because the working class will have power in the production of goods and commodities and hence hold the interest of everyone. When the bourgeois owns the means of production the majority of the people who are the working class are left out. Furthermore, Marx asserts that the impediment to freedom is the bourgeoisie. For instance, Marx argues that the bourgeoisie controls the means of production, robbing freedom from the working class by exploiting their labour. The different classes results in the working class being oppressed . The class of the bourgeoisie infringes upon the freedom of the working class in what he calls the â€Å" class struggle† to refer to a situation where one group has an advantage over the other group. This is so because the class that has an advantage will try and maintain its status quo and in so doing will establish norms that maintain that class. The working class person has no freedom in the capitalist world since he relies on the wages of his master. As well, since the laborer has no profits to be gained from the production that he doing, he is alienated him from the process of the profit making, which is a violation of his freedom. Furthermore, Marx argues that the majority of the wo rking class should fight for their freedom and overcome the tyranny of the bourgeoisie (Marx 73). This seems like the views of Mill who argues that the citizens are to have freedom and the state, which is in small minority, should not exercise tyranny over them. Nevertheless, for Mill, the impediment to freedom is the â€Å" masculine state, † (Mill, 219). For example, Mill argues that men control the affairs in public life and hence the women are forced to perform the duties of the private life. This implies that the half of mankind who are women are not free. In conclusion, this essay argues that Marx and Mill both share similar understandings of freedom such as the possibility of progress in society, the views that hold that freedom is an end in itself, and the idea that human nature for self-determination must be valued. However, both Marx and Mill pursue a different road in their conclusion of the concept of freedom. As described above, Mill’s argument argues that masculine is the impediment to freedom. This is so because most of the domestic work is done by women. Marx on the other hand views that the impediment to freedom is the bourgeoisie. Marx believes that capitalism is the problem for freedom and hence advocated for communism. As well, Mill advocated for freedom without the intervention from anyone or from the state as long as their action done does not affect others. Mill also argues against the norms of society that require the individual to conform. As well, he argues that the state should not interfere in the individu al`s affairs as this is a violation freedom. On the other hand, Marx suggests that the individual cannot be separated from the society. Thus the state can intervene in order to bring the society together and prevent other people from acquiring all the wealth. Ultimately Marx’s vision of communism is valuable because it is a vision that allows for the critique of contemporary society. As well, I would in conclusion, I would argue that capitalist system denies the majority freedom. For example, Even if you desire to have a certain type of work, you are not free to choose your boss. On the same point the people who controls the means of production have the freedom to choose among the abundance supply of labour. I would agree that communism in which the means of production is owned by many could have been a good society for mankind. Capitalism denies the freedom of choices to many people especially the poor. It lead to a few of individual controlling all the wealth. NB: The word freedom has been used interchangeably with the word Liberty. Work cited: John Stuart Mill, â€Å"On Liberty â€Å"Broadview Press.

Wireless LAN :: Internet Technology Computers Essays

Wireless LAN discovery through the use of applications such as NetStumbler, DStumbler, Wellenreiter and others is an increasingly popular technique for network penetration. The discovery of a wireless LAN might be used for seemingly innocuous Internet access, or to be used as a "backdoor" into a network to stage an attack. This paper reviews some of the tactics used in wireless LAN network discovery and attempts to identify some of the fingerprints left by wireless LAN discovery applications, focusing on the MAC and LLC layers. This fingerprint information can then be incorporated into intrusion detection tools capable of analyzing data-link layer traffic. Introduction The growth of 802.11 networks has been met with the development of several wireless local area network (WLAN) discovery applications. These applications are designed to identify WLAN activity and network characteristics, providing enough information for an unauthorized user to gain access to the target network. For obvious reasons, WLAN administrators should be concerned about unauthorized access to their networks and therefore should attempt to identify the applications used to discover their networks. WLAN intrusion analysis is not entirely unlike traditional intrusion analysis; we are primarily concerned about the identification of traffic signatures or fingerprints that are unique to the applications we want to detect. Unlike traditional intrusion analysis however, we have additional challenges that are unique to wireless networks: 1. Location of trafic capture station Where traditional intrusion detection systems can be location in a functional area (DMZ, inside a firewall, outside a firewall, etc), a data collection agent (agent) capturing 802.11 frames must be installed in the same service area of each wireless LAN we wish to monitor. The improper location of a wireless LAN agent will inevitably lead to false positive results. If the receive sensitivity of the agent exceeds that of the monitored network, traffic may be characterized as WLAN discovery while being outside the cell range of the monitored network. Another interesting challenge is monitoring "hidden node" IBSS stations where the last wireless station to generate a beacon is responsible to reply to probe requests (ANSI/IEEE, 126). In these cases, the wireless LAN agent may not be within the coverage area necessary to collect responses or further solicitation of management information from the responding â€Å"hidden node† station. 2. Identifying anomalous trafic In order for wireless clients to locate a network to join, the IEEE 802.11 specification made an accommodation for clients to broadcast requests for available networks.

If they tried rhomboids, Cones, waving lines, ellipses- As for example, the ellipse of the half moon- Rationalists would wear sombreros. "Six Significant Landscapes" (Collected Poems p.73-75) Wallace Stevens is considerd one of the most important poets of this century. His style was unique and diffrent. The way he used words to optain the reality of something that can't be touched, is an amazing and brilant talent. Stevens was a very successful lawer and business man as well as a great peot. We usually think of peots and artists as "starving artists." Stevens was a very accommplished lawer and was still able to write beautifull peotry. His peoms useually contadicted his lifestile, but that might be were he got his insperation. He had a wife, family, and career, he had a very queit lifestyle. But, his peotry is very loud and abstract. Wallace Stevens was born in 1879, in Reading, Pennsylvania. As a child, he started out at parochial schools, and later enrolled in public schools. Wallace's parents encourage him to read, which helped him become a better writter. In school, Wallace was an excellent student. After high school, he continued his education at Harvard University, where he became involved with two Harvard newspapers, first the Advocate and then the Harvard Monthly. After leaving college, he moved to New York City. He worked as a journalist, and considered a literary career. But, his father encouraged Stevens to become a more practical career in the law business. He worked as a lawyer for a few years in New York. He worked at different firms and then at the Fidelity and Deposit Company.

It was like Stevens led two separate lives, one of a business man and one as a poet. Stevens himself once said in a New York Times interview, "I prefer to think I'm just a man, not a poet part time, business man the rest.

"Six Significant Landscapes" (Collected Poems p.73-75) Wallace Stevens is considerd one of the most important poets of this century. His style was unique and diffrent. The way he used words to optain the reality of something that can't be touched, is an amazing and brilant talent. Stevens was a very successful lawer and business man as well as a great peot. We usually think of peots and artists as "starving artists." Stevens was a very accommplished lawer and was still able to write beautifull peotry. His peoms useually contadicted his lifestile, but that might be were he got his insperation. He had a wife, family, and career, he had a very queit lifestyle. But, his peotry is very loud and abstract. Wallace Stevens was born in 1879, in Reading, Pennsylvania. As a child, he started out at parochial schools, and later enrolled in public schools. Wallace's parents encourage him to read, which helped him become a better writter. In school, Wallace was an excellent student. After high school, he continued his education at Harvard University, where he became involved with two Harvard newspapers, first the Advocate and then the Harvard Monthly. After leaving college, he moved to New York City. He worked as a journalist, and considered a literary career. But, his father encouraged Stevens to become a more practical career in the law business. He worked as a lawyer for a few years in New York. He worked at different firms and then at the Fidelity and Deposit Company. He finally settled at the Hartford Accident and Indemnity Company, where he became the vice president for the rest of his life.

What gave rise to urbanisation in the mediterranean Essay -- essays re

â€Å"What gave rise to urbanisation in the Mediterranean region?† What is urbanisation? To ‘urbanise’ is to ‘make (a rural area) more industrialized and urban’ , urban meaning ‘of or living in a city or town’ . Marja C.V. Vink argues that â€Å"The word urbanization was used for the first time in Spain a little more than one hundred years ago† to show the â€Å"quantitative and qualitative growth if cities† . The degree of urbanisation is quite different when comparing towns or cities of antiquity to the modern understanding of an urban centre; however, essentially it is the same process. When talking about the rise of urbanisation in the Mediterranean region 3 main civilisations spring to mind, firstly the Greeks who were inspired by advanced civilisations of the Near East. Secondly, the Etruscans who ruled central Italy from the eighth century to the third century B.C. when the last Etruscan cities fell to Rome. Etruria was bordered to the south by the River Tiber and to the north by the River Arno. City states developed in Etruria in the eighth and seventh centuries B.C., and â€Å"by the last decades of the eighth century B.C. the centres which had undergone the process of urbanization and social diversification had acquired some of the status of cities.† Etruria flourished until the Gauls invaded in the fourth century B.C. From 616-509 Etruscan kings ruled over Rome. Finally, the Romans dating back to 753 B.C. with the founding of Rome by Romulus. Urbanisation is synonymous with cities. It seems impossible to consider a civilisation ‘urbanised’ if it does not have urban centres. So what is an urban centre? And why were these urban centres needed? Looking at what the cities consisted of can help one answer these questions. In Greece the most obvious choice for studying the process of urbanisation is Athens. I have chosen Marzabotto as the example of an urban centre for Etruria and finally, for the Roman Empire I have chosen Rome. These three cities all adapted to the needs of their population and the one thing common to all three is a cult centre. The first urban centres were certainly not Roman, however once urbanised Rome surpassed any of the Greek or former Etruscan cites in terms of monumentalisation. The Neolithic & Dark Age sees the beginning of domestication of plants and livestock, as well as the emergence of weaponry. With cultivation now possible peopl... ...biliography.

Two Types of Computer Software

COMPUTER SOFTWARE INTRODUCTION OF COMPUTER SOFTWARE Computer software or just call as software is about any set of machine –readable instruction that directs a computer precessorto perform spesific operations. One common way of dicribing hardware and software is to say that software can be thought of as the varible part of a computer and hardware as the invariable part. Hardware and software require each other neither has any value without the other. Software is a genaral term. It can refer to all computer instuction in general or to any specific set of computer instuctions.It is conclusive of both machine instruction that call the binary code that more human understand and source code that more human undestandable instructions that must be rendered into machine code by compiless or interoreters before being executed. On most computer plattforms software can be grouped into two broad categories. It is system software is the basic software needed for a computer to operate. The application software is all the software that uses the computer system to perform useful work beyond the operation of the computer itself.Software refer to one or more computer and data held in storage of the computer. In the other words, software is a set of programs, procedures, algorithm and its documentation concerned with the operation of the fuction of program it implemens either by directly providing instruction to the digitals electronics or by serving as input to the another piece of software. The term was coined to contrast to the term hadware. In the contrast hardware , software ‘ cannot be touched. Software is also sometimes used in a more narrow sense meaning application software only.Sometimes the terms includes data that has not traditionally being associated with computers, such as film, types and record . These are system software or operating system referred simply as the OS, application software and programming languages. Usually most of us interact with a c omputer using application software. * TYPES OF SOFTWARE APPLICATION SOFTWARE Application system includes a variety of programs that can be subidivided into ganeral-purpose and function-specific application categories. A normal user rarely gets to see the operating system or to work with it.But all of us are familiar with application software which we must use to interact with a computer. Application softwares are used to improve our work ability. Different application softwares and system softwares are used in daily life. Some are productivity software, content software, assessment software, online software, drill and practice software, problem solving software, tutorials, multimedia softwares, stimulation, games, group ware, share ware, spy ware, free ware etc . Some softwares are used to produce and create documents and different presentations. In the application software have four type. It is general purpose, custom software, commercial off-the –shelf(COST) and open source -software. Genaral-purpose application programs are programs that perform common information processing jobs for end user. For example word processing, spreadsheet, database management, and graphics prgrams are popular with microcomputer user for home,education,business, scientific and many other purpose. Because they significantly increase the productivity of end user , they are sometimes known a productivity packages.Other examples include web browsers, e-mail, and group ware, which help support communication among workgroups and teams. Costum software is an additional common way of classifying software is based on how the software was the developed. It is the term used to identity software application that are developed within an organization for used to identify software applicationthat are developed within an organization for use by that organization. In other words, the organization that writes the program code is also the organization that use the final software organization. Software that is developed for a specific user or organization is custom software. Since it is built for a specific user, its specifications and features are in accordance with the user's needs. Commercial off-the –shelf(COST). It is developed with the intention of selling the softwarein multiple copies and usually for a profit. In this case, the organization that writes the software is not the intended target audience for its use. Several characteristics are important when describing COST software.As opposed to custom software, off-the-shelf software is standard software bought off the shelf. It has predefined specifications that may or may not cater to any specific user's requirements. When you buy it, you agree to its license agreement. First as stated in our definition, COST software products are sold in many copies with minimal changes beyond scheduled upgrade release. Purchaser of COST software generally not control over the specification,schedule, evolution, or access to either the source code or internal documentation.A COST product is sold, leased, or licennsed to the genaral public, but in virtually all cases, the vendor of the product retains the intellectual prperty rights of the software. Costum software, in contrast,is gerally owned by the organization that developed it, and the specifications, functionality, and awnershipof the final product are controlled or retained by the developing organization. Open- source software is the newest innovation in software development. In this approach, developers collaborate on the development of an application usingprogramming standards that allow for everyone to contribute to the software.Futhermore , as each developer completes his or her project, the code for the application becomes the available and free to anyone else who wishes to use it. Open source software is available in its source code form and the rights to change, improve and sometimes distribute its code are given under a software license . Software developed by an individual or an organization, where the source code is closed from public (not available openly) is referred to as closed source software. SYSTEM SOFTWARE System software consist of program that manage and support a computer system and its information processing activities.For example. Operating systemand network management programs serve as a vital software interface between computer networks and hardware and the application programs of the ends users. System software is the backbone of any computer. It consists of all the files and programs that work to make your computer operate as a computer. System software is automatically provided when you purchase a computer on the high street, and is installed along with the operating system. Providers of system software include Windows and Apple Mac.These offer regular updates which can be installed for free as they become available. Examples of system software include assemblers, system utilities, tools and deb uggers. We can group system software into two major categories. System management programs. Program that manage the hardware, software network,and data resources of computer system during the execution of the various information processing jobs of users, example of important system management programs are operating systems,network managemant programs, database management systems and system utilities.System development programs. It is program that help user develop information system program and procedur and prepare user programs for computer processing. Major software development programs are programming langguage translators and aditors ,and variety of CASE and other programming tools. PICTURE OF TYPE OF SOFWARE REFFERENCE O’Brien, J.
