Impact of Privatization on Firms Performance

Impact of Privatization on Firms Performance 1.0 Introduction Privatization throughout the 1980s has been considered to be the solutions to the problems associated State Owned Enterprise (SOE)s both in the developed and developing economies and even in the socialist economies (Vickers and Yarrow 1995). In reality privatization is an economies policy and other times a political policy that is difficult to achieve mostly when is implemented in a corrupt setting like in most developing countries. However it is wise for a competitive and well regulated business environment structure to be established before privatization takes place. In recent times there has been a significant increase in the privatization of SOEs. Megginson et al (2004), suggest that political persuasion by government as a result of poor and unsatisfactory financial and operational results by SOEs has cause the transfer of ownership to private investor who will impact their business discipline in order to improve the level of performance for the newly privatized SOEs. While Aktan (1995) suggest that privatization goes beyond the sale of SOEs, assets or shares to individuals or private firms but in a broad meaning, it is to restrict government role and function in providing economic activities and put forward some methods or policies in order to strengthen free market economy. Privatization is often meant to be the transfer of control and ownership of government asset or firm to private investors. It could be partial or whole, through private placement or public offer of share via the capital market as well as through the distribution of vouchers. The major purpose of privatization is to grow and develop the economic by creating competition that can bring about efficiency ***. It will be right for the logical argument of this research study to compare or examine the different view of academics on what privatization means. Parker et al (2005) states that privatization is used to cover many arrays of different policies like liberalization, commercialization but in one of its studies, Privatization in Developing Countries: A Review of the Evidence and the Policies lessons, suggest that privatization means the transfers of productive asset from the state to the private sector, but also stressed that the most important factors to be considered is the introduction of effective competition and regulatory measures alongside with existing firms and for government to accept the political changes that occurs when privatization takes place. While, Beesley (1997) suggest that privatization is the formation of a companys act company and the subsequent sale of at least 50percent of the total shares of a company to private shareholders. However it is obvious now that privatization starts with the government transfer of its assets or a controlling share to private investors or shareholders in order to stimulate econom ic development. Privatization as an inherent part of government efforts to rationalize the SOEs. Its mostly done to reduce the burden on National Budget, improve efficiency of individual enterprise and ensure wider distribution of business ownership among its citizens and other foreign investors. However in most cases it brings about the introduction of market force (Demand and Supply forces) into the economy. Privatization can be set up to achieve different objectives depending on the Political, Economy and Social condition of each individual Country. This is due to the fact that what is applicable in the UK for instance will most likely not applicable in Russia due to the differences in techniques or method of privatization, general government objectives, SOEs condition, firms sectors activities and the countries characteristics. According to Bennett (2003) there are different methods used during privatization, either one used has its own advantage and disadvantage. The share option method is the mostly used method, it involves the sales of SOEs through the issue of shares to the public through stock market. For this method to be successfully implemented, the local country privatizing its SOEs must have an established Stock market where the trading of these shares should take place. Also there should enough public awareness to sell shares. While the private placement option which involves the sale of SOEs to the highest bidder helps government rise substantial revenue but the issues involved here, is the highest bidder will always want to get back their money back in time by exploiting the consumers. This option is mostly done in developing countries where there stock market is still very weak and there are trying to get foreign investor to invest. Lastly the voucher method which is common with Eastern Europe an countries like, Russia, Czech Republic etc, tends towards alleviating poverty. It involves the allocation of SOEs shares to virtually all local qualified citizens of a state in order for both the poor and rich to be co-owners of the SOE. But in most case the poor ones are more likely to sell their share to the rich one who will then have a controlling stake. 1.1 Background to the Study The telecoms industry is a sizable sector offering a wide range of products and services as well as employment opportunities across virtually all professional, skilled and unskilled discipline in the economy. However the industry has expanded and develop rapidly since late 1980s, in the 1990s and even more rapidly in most recent times due its consistency in constant need for Research and Development (RD), technological change on both the service providers and suppliers sides respectively in other to satisfy its market and be more efficient to maximize profitability. The telecommunication industry whether in a developed or developing economies has had its impact towards the growth and development of virtually all parts of an economy ranging from the political, social, financial, technological sectors over its 100 years of existence. However like every other service providing sector, it provides services to the local market and international market where business strategic is always aimed at gaining competitive advantage in the existence of competition and tight regulatory business environment in terms of providing service to users, expanding its economies of scale and scope and equity expansion. Many countries grant monopoly power to their local telecoms but establish an office that will regulate their activities and in other cases some merge their postal services and telecoms services together, example is the United Kingdom (UK). The UK Telecommunication has been in existence dating back to 1879, with its first telephone exchange established in Coleman Street, London. 1896 saw the Post Office take over the private sector trunk services while in 1912, all national telephone company exchange was controlled by the Post Office as a monopoly supplier of telephone service in the UK. The Post office had two departments the postal service and telecom. As a rule as stated by Ratto-Nielsen, telephone operations, the postal service where subsidized while labor union where paid high rents to organize labor. However in 1969, the Post office become a State Public Corporation and after the Carter Report of the Post Office Review Corporation was published, the 1981 the British Telecoms Act 1981 became law and the postal and telecoms of the Post Office became the responsibilities of two separate Corporation namely; The Post Office and British Telecoms (BT) Cable and Wireless, which was privatized. While BT was created as a Public Corporation charged with the responsibilities for Telecommunications, Supplies, Installations and Maintenance. The first competitive rivalry in the industry was the granting of license in 1982 to Mercury Communication Limited (MCL) to operate a fixed Link network in order to compete with BT. This only made a little impact as BT has a huge competitive advantage over MCL because it already had the market share, established and experienced Skilled employees and existing contracts with leading telecoms equipments manufacturers and service providers to operate and even if a year later both where give the advantage to operate without rival firms providing fixed link networks in the UK for seven years The Government White Paper published, proposed for the sale of 51percent of BT and the creation of a telecoms regulatory body, to be named Office of Telecommunication (Oftel) whose duties where to supervise all the activities going on in the telecoms industry and to also prosecute those who do not comply with the set rules and regulation of the industry as well as protect services users from exploitation. Two years later Oftel was signed into law and then administration of Margret Thatcher creating BT as a Limited Company wholly owned by the Government as BT Plc but was later privatized by selling off 50.2percent Shares to the Public. BT is one of the world oldest telecommunication Firm and dates back to be the first ever British telecom firm which also had the sole monopoly of providing telecom services in the UK with the backup of British Government. During the period, from 1878 the UK telephone service was been provided by the private sector companies, National Telephone Company (NTC) who were also faced with competition from the General Post Office (GPO) and in 1896 the GPO took over operation of the telephone service from and became a monopoly market for the in 1912 controlling the entire telecoms market in the UK. In 1965, some finding made by a working party was presented to the government which there found substantial enough. This lead them to split GPO into two divisions; the Post and Telecommunication which gave birth to BT and five units Post, Telecommunication, Savings, Giro and National Data Processing Services respectively. The Post Office act of 1969 made the Post Office to be controlled by the government and established as a public corporation. This gave them the sole right to run the telecoms system with listed power to authorize others to run such systems. However the Post Office retained its telecommunication monopoly. The Carter Committee of 1977 suggest for the restructuring of the Post Office into two separate units and further renaming of the Post Office to British Telecoms but it also remained a part of the Post Office. In 1981, the introduction of British Telecommunication act transfer the provision of telecommunication from the Post Office as a resulting establishing two different corporations a bold step to create competition in the utility industry (Telecoms). This empowered the trade and industry ministry and the British Telecoms the right to grant Licenses to other telecoms operators to run telecommunication systems therefore creating competition in the sector. However, in July 1982 the government officially announced her intention to privatize BT by selling up to 51 percent of BT shares to private investors. In 1984, more than 50 percent of BT was sold to the public through share option, then the largest ever most successful SOE privatization exercise in the history of privatization leaving the government with just forty 47.6 percent. This was about the most radical and the largest scale privatization exercise ever had in the history of Britain. However most investor where scared that it was going to fail. It was but in 1991 the government share of BT was reduced to 21.8 percent by rising up to  £5 billion and creating about 750,000 new shareholders of BT. In reality, the privatization of BT opened the telecoms market for other operates to come into the market, invest in the sector and breaking the monopoly advantage had by BT over the years by fighting for market shares through intense competitive business environment. This however forced BT into having fairer business policies, improved technology to optimize productivity as well as to raise its level of efficiency as government regulatory body would introduced a price cap system. On the other side this allowed other firms to spring up and compete with BT in the telecom sector bringing about maximum utilization of available resources, cost cutting and efficiency. Telecoms consumers where the most rewarded people as operator gave them the best deals ever in order to gain market shares. BT Plc is now run in over 170 countries all over the world and faced with about 150 other telecoms operator. This has forced them virtually to constantly to research and develop their existing technolog y as well as acquire new ones in order to keep pace with their consumers new and market share. 1.2 Rationale for this Study In this research study aims to examine the impact of privatization in the telecom sector in the UK post privatization era. Also it will examine if the method of privatization contributes to both the operational and financial performance*** 1.3 Objectives to the Study My objectives will be subdivided into two sections aimed at determining to what extends privatization affected BT performance in terms of one; financial performance By looking the determinants working capital management, Share price movement and it covariance relative to the telecoms sector and FTSE 100 and Financial annual report Secondly; operational performance Level of efficiency Market Share strategy Competition and Regulation 1.4 Limitation There are inevitable limitation to this research study caused by the different economy situation post privatization era of BT. This can be ranging from some systematic economy problems to specific economy problems that can either be a general issue associated with all other sectors of the economy or rather that has to do alone with the telecoms sector or BT performance over time. Also political issues that arise for political interference in BT or the telecom sector which can either be from change of government. Finally as a research study there will be minor statistical error but this research study still represent a substandard measurement of BT post privatization operational and financial performance within the very dynamic, rapid, competitive and volatile telecom sector indices and the FTSE 100 at large. 1.5 Research Questions Why would one witness a difference in performance in terms of operational and financial factors when a firm is managed by government compared to when been managed by the private individual or investors? 1.6 Structure of the Study In Chapter two, this study will focus on the methods of privatization while chapter three of this research is literature review which includes theoretical framework and a review of relevant literatures. The theoretical framework will look at the different theories of privatization, how those theories where applied during privatization and the impact it had in the telecoms sector. Also the literature will critically review the impact of privatization in the telecoms sector focus mainly on the operational and financial performance of SOEs before and after privatization. While Chapter four will discuss the methodology adopted to achieve this study. Chapter four will be analysis of datas and stating of findings. Finally Chapter five would be conclusion. Chapter two 2.0 Methods of Privatization 2.1 Introduction This chapter will focus on the different methods of privatizations ranging from share issue method to voucher or the mass method and finally the asset sales method. It will also discuss the justification why a particular method is chosen rather than the other toward the achievement of privatization exercise and finally the advantage and disadvantages of each method used. 2.2 Share Issue Method This method of privatization involves the sale of all or part of SOE to investor through a public share offer which are similar to initial public offer (IPO) in the private sector via the stock market. This is structured to raise money for the government, divest them also from ownership and for them to achieve political objectives. However in the words of Megginson (2005) this method is the largest and most successful method to transfer SOEs to private ownership. Yet it is the most dramatic because if it turns out successfully or fails respectively it becomes the most political and economy bad or good decision depending on what happens. However, the process of using this method involves the passing through three steps; How to transfer control: This involves whether to sell the whole SOEs strategically to the public once or step by step. If the last option is chosen then government will have to determine what percent should be sold initially and subsequently but the most important thing here is for the government to put up tight regulation to control corporate decisions after the privatization exercise. How to price the offer: The pricing decision requires whether government should do the pricing by tender offer, a booking-building exercise or a fixed price but whatever the decision government makes it must be in advance. However the government always issue out SOEs share below the true market value as an incentive to encourage investors to buy shares. Finally, how to allocate the shares: This depends on who the government intends to favor most, it could be the employees, labor unions or potential investors and even foreign investors. Also it could make use an investment banker as lead underwriter or favor national champion. Meanwhile this method of privatization needs the existence of a capital market and also has some comparative advantage over the other methods which is rationale behind why it can be used in some situation rather than the others. In most case SOEs share prices are underpriced relative to the market price, hence foregone government revenue that will make investor make a premium on top of there investment The needs to expand the stock market operational capacity to accommodate new issued equities Advantage Can raise huge amount of revenue for the government The strategy employed can be use to create wealth evenly for local investors by allocating a set percentage of share to every region within the country. This usually occurs in situation where there is less inequality of income The use of share option, most likely develops the capital market. It is also used when the SOE to be privatized is large and profitable. For example BT, It also transforms the size and efficiency of both the nations investment banking sector and its capital market. Disadvantage It is time consuming to organize It is extremely expensive to coordinate due to the fact that before the share are put to sale the government have to hire and pay consultants 3. Transaction cost is another issue. It include cost of sales, advertising, underwriting. 2.3 Asset Sales Method This method involve the sale of the whole or part of SOE clearly for cash to individual investors, group of investors or an existing corporation with or without experience in that sector (Meggison 2005). Vuylsteke et al (1995), suggest that transaction here can occur in different forms from direct acquisition by a similar corporate firm or private placement to targeting various institutional investors. However there are different procedures to follow in this method of privatization exercise. This includes; firstly the full competitive process which involves a privatization process of pre-qualification of bidders to win the final bid to take-over the said SOE. While the second procedure involves the use of direct negotiations between investors and government representatives to take-over the said SOE which usually involve the search for a larger number of investors. Both process would usually involve the investor who are either new or have an excellent record of both operational and financial performance in the past. This though is not a major concern for the government or standard to win the bid but can only be as confidence booster for both the government, SOE labor unions and management. However the governments have strict interest in the bidders that can meet their financial requirements as well as all other agreement without violating. Advantages It brings about a speedy and flexible negotiation towards the sales of SOE between the individual or group of investors and the government body that is interested in the transfer of the SOE to private hands. It can yield more revenue for the government as the highest bidder wins the ownership of SOE to be privatized It is the most reliable method of privatization in economies where the stock market is underdeveloped as well as encourage to a great extend property right theory. It attracts Foreign Direct Investment (FDI) cash flow income into the economies of the local country. It can also bring about innovation in technology, management skills and expertise especially when these SOE are bought over by foreigners. Disadvantages It is the least transparent method of privatization as the government might only target to sell to the group of investor that favors they own political objectives. It can bring about exploitation as the new investor might be under pressure to pay back loans and t the same time maximums profit within a short period of time. The group of investors or individual investor might not have the required technical expertise or skill and experience to run the new privatized SOE. These are mostly common with local investors favored by the government or are new in business. 2.4 Voucher Method This is also known as mass privatization, usually common in Eastern Europe. It is a method whereby eligible citizens of a nation can use vouchers that are distributed free or at nominal cost. This gives holders the right to bid for stake for SOEs or other assets been privatized. This method is mostly used in transition economies like in the Central and especially Eastern economies respectively to bring about fundamental change in the ownership of business asset in these economies, although not always change in effective control (Meggison 2005). However, low income distribution level prompted most nations in Eastern Europe to adopt this method of privatization as it became clear that the only viable way to privatize and maintain significant domestic ownership was the voucher method if not only individuals with the wealth to acquire shares which were communist, criminal and foreigners would buy up everything. (Parker and Saal 2003) This method of privatization as suggested by Boycko, Shleifer and Vishny (1994) shows that the reason to purse and specifically design the program is largely dictated by politics. This involves the divestment of SOE through the distribution of vouchers to a nations citizenry that people can use to bid for the SOEs on offer. This method has been used in mass privatization exercise programs mostly in transaction economies in the Czech Republic, Russia and other Eastern and Central Europe countries. However this method has been really successful in the past but most recently are failing because there do not attract new capital or management to the privatized SOEs. Experience has also shown that it do not provide effective ownership structure for the new privatized SOE instead insiders end up controlling most of the more valuable companies and ordinary investors receive claims of the weakest and least promising SOEs. Advantage It ensures a wide share of shares ownership, where as a lot of people would have been too poor to buy and own a share. Disadvantage It yielded no cash inflow to the government or firms and thus there were no transfers of technology, capital and expertise from foreign investors or multinational companies to the privatized companies. It also gave the new owners of the privatized who where existing managers and employee little incentives to effectively restructure the firms operation and reduce the amount of staff needed in order to cut cost. In most cases, government never gave up the full control of important privatized companies to private owners other than managers because government still heard a majority shareholding and thus felt that the firms will be too strategic to be left unsupervised. This was because government wanted to ensure that no serious staff cut which would have impact on operational restructuring as the exercise was politically rational but economically deliberate. Government allowed the politicization of credit extension also made the newly privatized firms continue to enjoy soft budget constraint for an infinite amount of time also contributed to one of the weakness of voucher privatization. 3.0 Theoretical Framework and Literature Review 3.1 Introduction The privatization of SOEs has over time been a big and important issue in the growth and development of the economy. This has lead to the development of many theories which explains the ideas behind what is expected in principle and practice in privatization exercise. This chapter will however discuss the relevant theoretical and empirical literatures of this research study objectives and rationale. This involves critically examining the theories that have been developed over time by different authors and how their impact privatization as regards the objectives of this study. This will also state why privatization is vital for the growth and development of some sectors and why, it will not in some other sectors within the economy. Finally, analysis on how privatization affects the performance of a firm will also be discussed. 3.2 Factors Determining Privatization SOE were highly inefficient and grow at a very slow pace, too much bureaucratic issue can cause no room for quick decision making, innovative changes. Also constant government political intervention as well as administration changes is an issue. It is also over dominated by the power of Labor Trade Union (Veljnovski 1987). However after the successful privatization of BT in 1984 by the Thatchers administration, it became an economic policy that can be used to reduce the financial pressure on government budget as well as the concern to prevent SOEs from failing in terms of its inefficient use of financial and operational resources. But could this be a means to wealth creation for investors, who through the spread and acquisition of shares ownership, restructuring and refocusing of SOEs economic objectives as well as cutting of trade labor unions influence and power will see SOE to maximize both there operational and financial performances. An argument that must be stressed here is that of the difficulty in interpreting the indictors of both operational and financial performance of SOEs post privatization within and outside the business environment economy. Take for example; poor financial performance may be consistent with high rate of internal efficiency if the formal is as a result of government policy of price control. However, since SOEs frequently respond to anticipated market failures, profit maximization and similar related measures might not necessary, be a reliable indicator for their poor performances over time (Ramanadham 1993). Rather this study will support that failure of SOEs, could be as a result of rapid demand for their goods and services faced by their steady but slow growth to reach maximum productivity movement rather than to totally shift production function to meet all demands and avoid poor operational and financial performance. Yarrow (1986), however argued against privatization stating that competition and more forceful accountability will even be better than privatization in promoting both financial and operational efficiency but his argument has a limitation, it only focused on a small number of company within UK. Ramanadham (1993) pointed out that the objective of privatization is realized more if it becomes successful within a short period of time either by stock market price rise or increase in the level of efficiency or productivity bringing about instance economic growth and development. But when reverse is the case (if it fails), which happens some time it even makes privatization more undesirable. So it is best re-engineer SOE by over hauling it, as well s to set up a transparent regulatory frame work to remedy what might be a failure when the objectives of privatization are not met as anticipated in order to level the firms operational and financial performance post privatization. In a further argument by Megginson et al (1994) whose strong support from recent theoretical and empirical perspective, that private firms will always outperform SOEs stating that privatization itself will always increase both the financial and operational efficiency of firms irrespective of the business environment. While another view by Moore (1992) who argued that the act of privatization promotes economic efficiency and public confidence (one of the major objectives of property right theory) in the system of industrial capitalism and thus SOEs should be sold off before efficiency gains can be realized. He also argued that the success of privatization transforms business attitude towards ownership, economic responsibility and towards the improvement of corporate performances. It also allows government play an important role of regulation the business environment leaving the ownership of firms in the hand of investors and individuals who will perform better as there are faced with scare resource and market forces. It is clear now that different factors can lead to privatization especially when SOEs has underperform operationally and financially causing political pressure, budget deficit and waste of scare resource for the government and even to the extent of administrative failure. 3.4 Evaluation of the theories of Privatization Principal Agent Theory Vickers and Yarrow (1995) points out that a problem exist in the principal agent theory as the principal interest greatly lies in profit maximization and high return for investment therefore this aim might conflict with that of the agent who might pursue other objectives apart from profitability. Further stating that since the formal do not have full information concerning what is happening within the SOE and cannot fully control the attitude of the agents who might be over ambitious and purse his own objectives, this will certainly create monitoring problems for the principal. This in fact creates both financial and operational problems directly or indirectly.** However when shareholders can influence the behaviors of agents (management) through vote as the only way to keep them in check, the agent might however work at a more efficient level and focus on a set objective towards profit maximization. On the other hand when the rate of efficiency increases, it leads to higher revenue which is mostly one of the objectives, to brings about higher income and dividend for its shareholders.** Property Right Theory This is a set of right to control assets. It is a consequently grants of authority made to an investor or a group of investors through right of issue of share or control either public or private and acknowledged by other persons or organizations (Lindblom, 1977) De Soto (2006) argues that lack of formal property right is what has kept developing economies from been developed stating that it limits the amount of goods and services that can be exchanged in the market in order to have a sustainable long term economy growth. While Easterly (2001) opinion is quite similar to the views of Soto, Easterly suggests that property right is a s

Honour Killings: Causes and Strategies for Intervention

Honour Killings: Causes and Strategies for Intervention What is honour killing? Every year, hundreds of women are killed in the name of honour by their family members because they have brought shame to the family and the community. Honour killing is defined murdering a member of the family in the name of honour, it is usually the female who is murdered for bringing shame to the family. In rare cases, men are also murdered if they bring dishonour to their family or community. It is believed that honour killing is a private family affair and it should remain between the four walls of the house, no accurate statistics are available on this social evil. It should be noted that honour killing is a gender-neutral concept but overwhelming majority victims are women. The only fundamental difference is that the male accussed of dishonouring might be given a chance to explain his situation before the trible leaders and can escape the death penalty by giving compensation to the family who has been ‘dishonoured’. Women are rarely given oppurtunaties to explain their side of the story and the only possible way to restore the honour is by killing the women who has brought shame to the family. Where does it take place? Pakistan consists of four provinces known as Sindh, Balochistan, Punjab and North West Frontier Province(NWFP). The menance known as honour killing frequently all four provinces of Pakistan. In Sindh, the practise of honour killing is known as â€Å"Karo Kari†, meaning ‘black female’ and ‘black male’. In Balochistan it is known Siahkal. The majority of the honour killings take place in rural areas, however, there have been some reported incidents of honour killings in urban cities of Pakistan such as Karachi and Lahore. How can one be dishonoured? Honour killings for a choosing a marriage partner According to the article 16 of Universal Declaration of human rights, both men and women of full age, irrespective race, religion and nationality can enter into marriage with any partner of their choice. It is our fundamental to marry a partner of our choice, however in Pakistan, women are not encouraged to have this right because women are seen as personal property of a man, therefore women should exercise their right. Women are seen as commodity owned and controlled by their fathers, husbands and brothers. Women are not suppose to express any desires and feelings contrary to the wishes of their fathers, husbands, and brothers. Traiditionally women are not allowed to choose their partners for marriage. The head of the family, usually the father, chooses the groom. the bride does not have any say in the process and any defiance against the process is considered a taboo. Women who have been succesful in marrying partners of their choice are often threatened by their father that charges of zina(unlawful sexual relations) would be brought against them. Under the islamic law of marriage, the wali(the closest male adult relative) has the responsibilty and authority with respect to marriage, the wali is usually the father and if it can be proved that the father did not give consent to the marriage then it will be considered invalid, if marriage is invalid then any sexual relations which took place between the man and the women would amount to zina. Most of the time, family members take matters into their own hands instead of going to court. A women who married a man of her choice was murdered outside Peshawar court by her brother in the name of honour. Women seeking divorce The article 16 of Universal declaration of human rights states that men and woman should have equal rights regarding dissolution of marriage. Under Islamic marriage law, a man is allowed to divorce his wife anytime, the divorce can be given verbally but a women cannot divorce her husband, she can apply for Khula(Separation) in the court of law. Divorce is seen as a very serious problem in the muslim world and muslim women are enouraged to avoid divorce at any cost, even if it means by putting up with a severely abusive husband. In 1999, Saima Sarwar was shot dead in a lawyers office because she attempted to obtain divorce from her husband severely abusive husband. The killing was instructed by her uncle but he was soon released Qisas and Diyat laws which states that the person(s) involved in killing will go free if he is pardoned by the Wali of the victim.Her uncle went unpunised as he was pardoned by her husbad and father in the capacity of Wali. It should be noted that Saima Sarwar belonged to a upper-class prominent family, her father is a entrepenuer and the mother is a doctor, this case shows the social evil in question is a cause of concern for both rural and urban population. The local newspapers in the region overwhemingly supported the killing, arguing that it was accordance to the tradition and therefore it cannot be a crime. Honour killings for rape A woman brings shame to the family if she becomes a victim of rape. In 1999, a 16 year old mentally-retarded girl was raped on many occasions by junior clerk of the local government department of agriculture in hotel in Parachinar, NWFP. The uncle of the girl lodged a complain, the accussed was taken into protective custody and the girl was handed to her tribe. The Jirga(tribal court) decided that she has brought shame to her tribe and the honour can only be restored by killing her. She was shot dead in front of tribal gathering. Get rich quick scheme? Ratio of honor killings is higher in those provinces where agriculture lands are abundant. Land is the main reason behind a majority of honor killing incidents in Sindh and Punjab. In overwhelming majority of cases, there is always a ulterior motive such as lust for money, land, lust for another women or to conceal other crimes. Many individuals exploit the concept of honour killing for gaining compensation or land. If both accused of karo kari are murdered then the matter usually ends but if only kari is killed and karo escapes, the karo has to compensate the affected man by giving him money, land or another women. Nafisa Shah, a leading human rights activist describes honour killing as industry which has range of stakeholders including tribes people, police administration and tribal mediators, honour killing is used as an excuse to hide sins and gain money. Police accept bribes of about 7000 rupees(equivalent to  £70) for not investigating claims of honour killing. The International Law International human rights law recognises â€Å"honour crimes† as a form violence against women, therefore it is a direct violation women’s right to life and security; freedom from torture and cruel, inhuman, and degrading treatment; and the right to equality before the law and equal protection of the law. Honor crimes also violate rights guaranteed to women by the UN Convention on the Elimination of All Forms of Discrimination against Women (CEDAW), such as the right to freely choose one’s spouse and the right to equality in marriage. CEDAW’s General Recommendation Number 19 defines gender-based violence as a form of discrimination against women and makes explicit reference to honor crimes. CEDAW obligates States to protect women from gender-based violence, including violence committed by family members and to prevent, investigate, and punish acts of violence against women. The Convention also requires States to disqualify honor as a legal defense for acts of violence against women. The UN Declaration on the Elimination of Violence Against Women echoes these obligations and states that, States should condemn violence against women and should not invoke any custom, tradition or religious consideration to avoid their obligations with respect to its elimination (Article 4). International human rights law is enforced through the state and by way of treaties. A state becoming the party to a international treaty will be bound by th treaty and it is the state’s responsibility and duty to protect the rights of the citizens. Pakistan is a party to a â€Å"Convention on the Elimination of All Forms of Discrimination against Women†, the treaty has been ratified and as a result of that, the Pakistani government ammended the Criminal Act 2004 which makes â€Å"Honour killing† a punishable offence. Apart from making the ammendment to Criminal Act 2004, Pakistan has taken several other intitaves to curb honour killings and domestic violence against women: Establishment of Gender Crime Cell Gender Crime Cell was established in National Bureau on 1st April 2006 to curb violence against women. The function of the Cell is to gather, collate and analyse data on cases of violence against women. The cell will act as central repository of relevant data on cases of violence against women and it will assist top-policy makers in developing holistic and effective policy countermeasures to control the social evil volence against women. Gender and Human Rights Sensitization To sensitize the police and to further improve law enforcement response to human rights situations, a comprehensive program has been included in the cirruculum of police training schools, police training colleges and national police academy. Cooperation/Collaboration with NGOs/ Civil society National Police Bureau has welcomed visits from NGOs who monitored severall police stations across the country, the main aim was to look into the business procedures, handling of public complaints against police, infra-structure, and facilities in lock-up of the stations. According to the Government of Pakistan, all these measures will help directly or indirectly contribute against curbing crimes against women. After reading the responses submitted to UN by the Government of Pakistan regarding the issues relating to violence against women, one would get the impression that Pakistan is trying to tackle the problem, some measures have been to curb the problem mentioned but the measures taken are not adequate enough to protect women, controversial laws such as Qisas still exist which are often exploited by murderers. Qisas Law Qisas law is relates to offences involving bodily injury or loss of life. The aim of the Qisas law is to put the victim’s family in control, ir is up to the family members of the victim to decide whether to bring an action against the murderer or pardon the murderer. Under the law, murdering a family member virtually carries no punishment as the other family members have the right to pardon the killer. In June 2002, Zakir killed 18- year Sabiha on suspicion that she had become pregnant, Zakir was pardoned by uncle of Sabiha, therefore his crime went unpunished. In a situation like such as this, courts and law enforcement agencies cannot take further action if the pardon is granted by the family member of the victim. n 90 percent cases of honor killings, the culprits are close relatives and therefore they are easily forgiven by the family of the deceased, in order successfully tackle this social evil, Qisas and Diyat Ordinance should not be in practise at all as it allows murderers to walk away free. It is evident that more needs to be done to tacke the menance known as honour killing, but the question what can the further steps can UN take to ensure that Pakistani Government makes further ammendments to the law to ensure that no murderers goes unpunished? The role of United Nations The human rights machinery in the UN systems works in three areas: information, analyis and policy development; provision of support to human rights bodies and organs; and promotion and protection of human rights. In order for this machinery to be successful, the UN has developed human rights institutions at the country level. The Office of the High Commissioner for Human Rights(OHCHR) assigns human rights advisers to country teams and their aim is to advance human rights through legislative, judicial and other enforcement mechanisms. The UN has created commitees to oversee implementation of implementation human rights but the commitees have a limited power to investigate or monitor violations of human rights. The UN machinery is merely way of recording information. If a state fails to comply with demands of UN then procedures usually range from coaxing to naming and shaming, it is very rare that sanctions are imposed for human rights violations because of the undesirable consequences. UN is also having monetary problem, many of the major member states have refused to pay their assesed share of costs, the guaranteed budget of OHCHR has fallen less than half. United nations is not effective in curbing human rights violations, it has no other to make sure that the human rights are not violated, they do not have effective mechanisms to make sure that human rights are enforced and they do not have the necessary resources. Simply by signing and ratifying a treaty does not ensure that the State will carry their duties and protect human rights. The only serious measure which the UN can take is impose sanctions. It is possible to impose sanctions solely on the basis of human rights, imposing sanctions for breaches of human rights is rare. Should the UN impose sanctions to pressurize the Government? UN can impose sanctions such as diplomatic isolation , restrictions on international travel, trade and financial transactions. Sanctions is regarded a tool created to ensure that States comply with demands of UN. Imposing may seem as attractive option but it can discredited on the basis of its harsh consequences on the citizens of the state. Sanctions have a bad history as they inflict undeniable pain on the citizens which the UN is trying to protect. If UN was to impose trade and financial sanctions to pressurise Pakistan to do more to curb honour killlings, then it is highly unlikely the sanction will work because Pakistan already a poor country, 17% of the population lives under $1 a day. Pakistan economy nearly went bankrupt as a result of sanctions imposed by UN for carrying out nuclear tests. Economic sanctions means that the Pakistan economy will suffer and therefore the people of Pakistan will suffer, the overall level of poverty will increase and it is likely that honour killings will increase as well because honour killings are often carried to gain compensation or land. Sanctions will have a counter-productive effect on Pakistan, therefore it should be avoided. The role of NGOs Traditionally NGOs are considered to be more effective than United Nations, in the sense that they are better at monitoring than UN. NGOs tend to focus on one issue at a time compared to UN which focuses and many issues at a time, thus there is overload of work within the UN, therefore the procedure of monitoring is not effective. NGOs do not have any authority, it can pressurise Government by way of protest, NGOs can run aware campaigns and provide support and counciling services to the victims. NGOs cannot directlty enforce human rights, for human rights to be enforced, NGOs rely on courts, there are still loopholes in the law which favour the murderer, unless the loopholes are closed, the NGOs will not be effective. Majority of ‘honour killings’ take place in remote areas such as NWFP due to poor infrastructure, as a result of poor infrastructure, it can be very difficult for NGOs to monitor remote areas of Pakistan. According to Khawar Mumtaz, a leading human rights activist said there were many as eight NGOs working in the NWFP and for betterment of women. The organisations were targeted by religious extremists, the houses of workers and directors were destroyed. The NGOs had to close their operations and flee from NWFP because of security concerns. Who else can help? Apart from the United Nations and NGOs, countries such as United Kingdom can help to tackle problems such as ‘honour killings’ in Pakistan by giving them aid, which then can be used to improve the situation of human rights in Pakistan. The United Kingdom donated  £2m in 2006 to set up a gender and justice protection fund, the main aim of the fund is to curb violence against women. Many critics argue that the aid which is given is not always spent on protection of human rights due to high levels of corruption within the the Government. How can we fight this social evil? Legal measures The Government of Pakistan must repeal the Qisas law as it provides a loophole for murderers to exploit, the fight against the menance cannot be won unless Pakistani Government makes further ammendments to law. Adopt a legislation which would criminalise all forms of domestic violence, The UN has developed a framework for a model legislation which can be adopted. Honour killing should be treated as a crime against the state and Preventive measures Run campaigns to inform citizens of their human rights througout the country. Currently Ministry of Law, Justice and Human Rights is running a human rights mass awareness campaign throughout the country. The campaign is approached through print and electronic media, the campaign is delivered in the form of jingles, talk shows, commercials, slogans and promotional material in the Newspapers. In remote areas such as NWFP and interior Sindh, the people don’t usually have access to electronic media or newspapers. The literacy levels are low in pakistan, the literacy rate for women in 16%, this means that media is ineffective in remote areas because there is no televisions and majority of the women cannot read and write. The women who live in remote areas are most vunerable. Honour killing crimes are under-reported, as a result it is not possible to estimate the real magnitude of the problem. Monitoring and collecting information would help the Government to understand the problem better, and therefore it will enable the Government to come up with better strategy. Protective measures Provide adequate protection to human rights activists and lawyers, often leading human rights activits such as Hina Jilani and Asma Jehangir. In one incident, the two daughters of Asma Jehangir were assaulted and illegally held for several hours along with their friends by armed persons because they were making a video clip. The police did eventually arrive but failed to take any action againt the perpertrators, the police asked Asma Jehangir to remain quiet otherwise the girls would be kidnapped, raped and killed. If activists are not adequately protected by law enforcement agencies then they will not be able to fight for protection of human rights. Long term strategies Honour killing is not a recent phenomoen, similar practices have been known since ancient Roman times, when the Pater Familias (senior male within a household) retained the right to kill an unmarried but sexually active daughter or an adulterous wife. In order to fully eradicate this menance, we should look at the true root causes in order to curb this heinous crime against women. The three main factors are: Male domination Financial dependency Lack of education Male domination Both men and women should be represented equally in all public institutions, most importantly there should be proportiante representaion of women in the Government. The National Assemebly of Pakistan(equivalent to Parliament) has a total number 342 seats and 60 seats are reserved for women, only 17.5% of seats are occupied by women, in order to protect rights of women, it is imperative they are represented proportionaly in the Government. At the moment, there are few women in the Government who are holding key Government ministry, Sherry Rehman is the only women who is holding the Ministry of Information and Broadcasting which considered one of the important ministries. Recently Dr Fehmida Mirza was elected as the Speaker of National Assembly, she is the first woman is Pakistan to be elected as the Speaker of Natioanl Assembly. Late Benazir Bhutto was the first female prime minister of a muslim country. To end male domination, women should participate in politics, proportiante representation would mean that it will not possible to pass discriminatory laws in future against women such as Hudood ordinance as women would have a greater say in the law making process. Financial dependency Agriculture is the largest of economy of Pakistan, 79.8% of rural women are engaged in some sort of agricultural work. Majority of rural women have dual responsibilties, they have to look after house and work in agricultural land as well but they are grossly underpaid, in many cases they are not paid at all. Most women living in rural areas of Pakistan are not aware of their rights such as equal pay, the Government should run campaigns to empower women and inform them of their rights. The Government should run courses to give women vocational training, this would improve women’s capacity to earn by increasing women’s access to source of livelihood, in particular cottage industry, livestock production and agriculture. Only 9% of the jobs in the services industry of Pakistan are done by women. The Government should encourgae equal employment oppurtunities, it was only 2001 when an Act was introduced which ensures equal remunaration for men and women for work of equal value. Study carried by a NGO confirmed the widespread occurrence of sexual harrasment of women at the workplace, the Government of Pakistan been able to implement laws which adequately protect women at the workplace. Government should undertake measure to make places more safe so women could work without fear of discrimination and harassment. Lack of education Only 16% of women in Pakistan are literate. Illiteracy rates are very high Pakistan. The education sector in suffering from inadequate financing and infrastructure. The budget allocated to education sector is low, Pakistan is one of the twelve countries who spend 2% of their GDP on eduction sector. Education needs to be improved, more schools are needed in Pakistan so more girls could attend school. How practical is it to enforce rights in Pakistan? Lack of eductation and financial independence are the main factors which stop from going to relevant law authorities for protection of their human rights, low literacy rate and lack of awareness does stop women for seeking protection against violations of human rights. Also approching the judiciary through a lawyer can be a expensive proposition, therefore women do not attempt to take any action. Democracy and human rights It is believed that military regime are the worst offenders of human rights, from November 1999 to Feburary 2008, General Pervez Musharraf, a army general has enjoyed absolute power over Pakistan. In his term many human rights abuses took place such lal masjid killings and he sacked 12 judges out of 17 judges to install his own hand picked judges. General Pervez Musharraf’s human rights record has been poor. Elections took place on 18th Feburary 2008, most specators believe that elections were free and fair and democracy was restored. Recently the new Government ratified a key UN human rights treaty and signed two others, this suggests that the new democratic Government is serious about human rights issues and the position of human rights should be better under the Government of Pakistan People’s Party. For many years, a military general had absolute power over Pakistan, the military regime was rarely criticised by USA or UK because of Pakistan position against war on terror, infact he was praised by George W Bush and Tony Blair for his role despite the fact that he committed various violations of international law during his tenure, UN never imposed any economic sanctions on Pakistan, infact economic sanctions were lifted which were on Pakistan for conducting nuclear tests in 1997 after he promised support to hunt Osama bin Laden. Human rights violations in Pakistan are often ignored by major member states such USA and UK. The major member states did provide immunity to a dictator against human right violations, If USA and UK would have not supported Musharraf and would have taken steps earlier to restore democracy in Pakistan then the human rights situations would have been far improved by now. Jirga system Jirga is defined a tribal assembly consisting of male elders of the tribe. Majority of the cases relating to honour killings are decided in Jirga instead of a formal court. Jirga should be banned because the system is unfit to provide justice to women, male elders are biased towards women, trial by jirga is the prime protector of the tradition of honour killing. The tribal assembly usually consists of uneducated male elders who do not have the knowledge and the skills to judge. They do not have any jurisdiction to impose capital punishments. Sindh is the only province of Pakistan where the panchayat(equivalent to Jirgra system) have been banned, Jirga system still operational in Baluchistan and North West Frontier Province of Pakistan. Jirga system should be be completely banned throughout Pakistan, the only reason why Jirga system is still operational in rural parts of Pakistan because it seen as a cheaper alternative. Any hope? Pakistan is grappling with many crisis at the moment, the burning of judiciary is still unsolved. There is shortage flour and food prices are rising dramatically. There is severe shortage of basic neccesaties such as electricity and clean water in Pakistan. Recently, one of the most popular leader of Pakistan was shot dead. The new Pakistani Government is facing many problems and as result of that, they are not able to fully concentrate human rights issues, honour killings have rarely received any attention from the media or the new Government. We can only hope that the new Government takes positive steps to curb this social evil, so far there has been no progress made by the new Government to address this problem. Pakistan as a suffering from increasing unemployment, increasing inflation and growing anger and frustrations with the system, lack of opportunities, all these factors can lead to violence against women, all tend to build aggravation in men. At the end of the day, it’s the women who are at the receiving end of the vented frustration, thus violence against women occurs as a direct result.

John Keats Essay -- essays research papers

English Literature Biographical Speech Keats, John (1795-1821) English poet, one of the most gifted and appealing of the 19th century and a seminal figure of the romantic movement. Keats was born in London, October 31, 1795,and was the eldest of four children. His father was a livery-stable owner, however he was killed in a riding accident when Keats was only nine and his mother died six years later of tuberculosis. Keats was educated at the Clarke School, in Enfield, and at the age of 15 was apprenticed to a surgeon. Subsequently, from 1814 to 1816, Keats studied medicine in London hospitals; in 1816 he became a licensed apothecary (druggist) but never practiced his profession, deciding instead to be a poet. Early Works Keats had already written a translation of Vergil's Aeneid and some verse; his first published poems (1816) were the sonnets "Oh, Solitude if I with Thee Must Dwell" and "On First Looking into Chapman's Homer." Both poems appeared in the Examiner, a literary periodical edited by the essayist and poet Leigh Hunt, one of the champions of the romantic movement in English literature. Hunt introduced Keats to a circle of literary men, including the poet Percy Bysshe Shelley; the group's influence enabled Keats to see his first volume published, Poems by John Keats (1817). The principal poems in the volume were the sonnet on Chapman's Homer, the sonnet "To One Who Has Been Long in City Pent," "I Stood Tip-Toe upon a Littl...

The Power of Delegation Essay -- Delegate Engineering Management Essay

The Power of Delegation Delegation is a management tool that can be used to empower or when abused can be a detrimental force in a company. Delegation can aid employee growth and development while getting the job done efficiently. The true purpose of delegation is to accomplish the task by assigning it to someone else (Blair, 1992). Many misunderstand the concept of delegation and therefore either will not delegate or improperly apply the principle which provides unsuccessful results.   Ã‚  Ã‚  Ã‚  Ã‚  The primary reason to delegate tasks is to get the work done. The manager must be wise enough to know that he or she cannot be everywhere and do everything. A manager must also realize that along with the assignment of the job to the subordinate, the authority to complete the task must also be given. The delegation of authority is the hardest, most difficult part for some in management positions. If the task is assigned without the authority to use independent discretion the result is frustration and incomplete production. The manager must clearly communicate the expected result also ensure that the subordinate is properly trained and/or has the required skills needed to accomplish the assigned task.   Ã‚  Ã‚  Ã‚  Ã‚  Communication is a major component of successful delegation. A system of regular exchanges of information between management and employees ensure that each party is aware of what others are doing (Blair, 1992).   Ã‚  Ã‚  Ã‚  Ã‚  My current employer is a nonprofit organization, which is run by a Chief Executive Officer/President who was hired 22 years ago. Her background is in education, as a principal, with a master’s degree in Education Administration. The CEO answers to a board of directors, which have been very good at delegating the responsibilities of running the corporation to the CEO. The board meets monthly to receive reports on the activities and financial status of the facility but other than that have no real hands-on role in the management of the company.   Ã‚  Ã‚  Ã‚  Ã‚  The CEO has a very different approach to delegation than the board of directors; she tends to micro-manage her staff. Her idea of delegation leans more to assignment of a task and proceeding to dictate exactly how she desires the task to be accomplished or assigns the task without giving authority to carry it out. The CEO makes assignments to members of her Corporate Leadership Team (program direct... ...tion for his staff. The director is not confident in his own competency yet feels the need to improve upon the work his staff produces. This is not a simple problem because the director, a vice president in the company, needs to work out personal issues in order to stop the offending actions. He can however recognize that the problem exists and redirect his interference. Overall this company would benefit from formal training in the functions of management along with methods of applying the principles of management in their own jobs. A section on delegation would need to consist of the definition of delegation, the importance of communication, developing effective and efficient controls, how delegation aids in employee development, how to maintain proper access or assistance to the delegate and awareness of the possible outcomes and failures when using delegation as a management tool (Blair, 1992).

Inner Journeys Essay

What extent has studying the concept of inner journeys expanded your understanding of yourself individuals and of the world? Inner journeys are about the process in which we move from naivity to maturity. In this proccess we learn new things about ourself that help us grow and become wiser and better people. The texts cosi by louis Nowra, the film groudhog day and the poem the road not taken all depict journeys of the mind and spirit which open up a greater understanding of the sense of self. In cosi louis nowra presents the inner journey of lewis, a young first time director who is hired to direct a play to bring the inmates of an asylum ‘out of their shells ‘. At the begining of the play lewis is indecisive in his understanding of others, uncertain of his opinions and unconfident of his own abilies. Diresting cosi fan tutti with emotionally and mentally handicapped people is the catalysts for lewis’ own emotional and mental maturity. As a metaphor for the world the charred theatre represents the challenges that will confront lewis. The characterization of lewis is established by the realism that of his language when he initially states † i need the money. However this realism is threatened when both nick and lucy leave him alone to deal with the inmates. lewis’s growing fear and uncertainty is emphasized through Nowra’s stage directions. Gradually as lewis spends more time with the patients like when he like when he lies about cherry â€Å"thats why she spends so much time in the toilets in order to keep the production going he starts to see the value it has for them. Lewis also changes his attitude toward love and fidelity. This evident in the contrast when he says † loves not so important nowadays† to now saying â€Å"without love the world wouldn’t mean much†. Nowra uses the play within play within play structure to emphasize the importance of love and fidelity. The opera cosi fan tutti functions somewhat as a mimetic device as it becomes a reflection of lewis’ relationship with lucy and his realisation that fidelity is an essential part of love. The inner journey that allowed lewis to gain this insight has been a product of his relationship with the mental patients. Finally lewis develops personally as a a director. Initially conveyed as a timid character, evident as roy talks over him, he learns to control and direct as he gains the respect of the mental patients. The film groundhog day starring bill Murray show’s the Inner journey of Phill as he is trapped in a recurring day. Through the brilliance of the plot we can observe as he deals with his unique predicament. We see how he struggles to find meaning and purpose in life. Each day he experiments with new thoughts and behaviors and he learns what works and what doesn’t. Any change that occurs must be inside him because only he can change. All the other characters repaet eaxcly what they did the day before. This shines an intense light on Phils abilty to change himself. Over countless days he learns that what pleasure he thought would make him happy have failed to, and he has to accept his old self has completely run out of steam. From this he is forced to place all his attention on changing the way he interprets the world, on his personal reality by changing his attitudes, values thoughts and feelings. like lewis he literally recreates himself becoming a mature. loving and giving person. His journey proves that inner change is the key to personal growth and happiness. The road not taken by Robert frost uses a metaphor of traveling to explore our chooses in life. It depicts the difficulty of making choices available and presented to people. Frost traces the way we make decisions, enjoying the options life has to offer us yet he also acknowledges that we cannot realistically do everything that is presented to us. The first person perspective instantly brings the audience close to the experience being recounted. The use of ‘i’ establishes the personas personal dilemmas as his journey brings him to â€Å"two roads diverge in a yellow wood†. â€Å"Two roads† and yellow woods are metaphors for the choices he confronts. Rhyming creates a flow to the piece while the rhythm forces us to pause effective for thinking what the persona is contemplating. Stanza 1 shows that persona is ‘sorry i could not travel both’ roads and show that life’s journey requires chooses that exclude alternatives. The second stanza shows that the choice has been made. The use of the language â€Å"As just as Fair and † Perhaps suggests both roads are equal. However there is slight confusion of the personas choice, conveyed in ‘perhaps the better claim, really about the same’. At the time of his choice he believes it was a better claim than the other. Later he thinks there much the same. In the third stanza, the exclamation ‘ oh I kept the first for another day†! suggests the optimism of being able to retread ones steps and take life’s journey by a different route. But the use of the conjunction ‘yet’ he later says ‘ I doubted if i should ever come back’ which suggests that after taking one route, That’s the route he has to live by, it is a choice he has made in life. Finally in the last stanza the pause suggests regret. The persona is now not sure if he took the better route but this decision is one we have to make in life and we have to life with the consequences and hopefully learn from our past experiences. The poem suggests that inner journeys are irreversible and the choice we make define the person who we become and our understanding of life and the world. This idea is similar to lewis experience where his decision to direct Cosi fan tutti moulds him. Through a close analysis of the three texts Cosi, The film Ground hog day And the poem the road not taken by robert frost that convey the ideas that an inner journey forms as a response to life’s changes and particularly the climatic moments which force a spiritual, mental and emotional re-evaluation of values of priorities.

Internetworking End-to-End Requirements Essay

– Hence such characteristics as: performance, reliability, scalability, mobility, and QoS of DS are impacted by the underlying network technology and the OS ? Principles of computer networking – Every network has: ? An architecture or layers of protocols ? Packet switching for communication ? Route selection and data streaming ? Comm Subsystems (network technologies rest on): – Transmission media: wires, cables, fiber, wireless (sat, IR, RF, mwave) – Hardware devices: routers, switches, bridges, hubs, repeaters, network interfaces/card/transceivers. – Software components: protocol stacks, comm handlers/drivers, OS primitives, network-focus APIs ? Hosts – The computers and end-devices that use the comm subsystem – Subnet: A single cluster or collection of nodes, which reach each other on the same physical medium and capable of routing outgoing and incoming messages – The Internet is a collection of several subnets (or intranets) ? Networking issues for distributed systems – Initial requirements for DS applications: ftp, rlogin, email, newsgroup – Subsequent generation of DS applics. : on-line shared resources. – Current requirements: performance, reliability, scalability, mobility, security, QoS, multicasting ? Performance – Key: time to deliver unit(s) of messages between a pair of interconnected computers/devices – point-to-point latency (delay) from sending out of outgoing-buffer and receiving into incoming-buffer. Usually due to software overheads, traffic load, and path selection – Data transfer/bit rate: speed of data transfer between 2 computers (bps). Usually due to physical properties of the medium. ? Message trans time = latency + length/bit-rate ? Bandwidth vs. bit-rate. – The total system bandwidth (volume of data sent and received in a unit time, e. g. , per sec. ) is a measure of its throughput – Bit rate or transfer rate is restricted to the medium’s ability to propagate individual bits/signals in a unit time – In most LANs, e. g. , Ethernet’s, when full transmission capacity is devoted to messaging (with little or no latency), then bandwidth and bit-rate are same in measure – Local memory vs network resources: ? Applications access to shared resources on same network usually under msec ? Applications access to local memory usually under msec (1000x faster)? However, for high speed network web-server, with caches, the access time is much faster (than local disk access due to hard disk latency) ? Scalability (Internet and DSs) – Future growth of computing nodes of Internet (hosts, switches) in 109’s (100’s of 106 hosts alone) – Requires substantial changes to routing and addressing schemes (more later! ) – Current traffic (load) on Internet approx. measured by the latencies (see www. mids. org), which seem to have reduced (with advances in medium and protocol types). – Future growth and sustainability depend on economies of use, charge rate, locality/placement of shared resource? Reliability – Failures are typically, not due to the physical medium, but at the end-end (at host levels) software (application-level), therefore, error detection/correction is at the level – Suggesting that the communication subsystem need not be error-free (made transparent/hidden to user) because reliability is somewhat guaranteed at the send/receiver ends (where errors may be caused by, e. g. , buffer overflow, clock drifts causing premature timeouts) ? Security – Most intranets are protected from external (Internet-wide) DSs by firewall. – A firewall protects all the resources of an organized from unlawful/malicious access by external users, and control/monitoring of use of resources outside the firewall – A firewall (bundle of security software and network hardware) runs on a gateway – the entry/exit point of the corporate intranet – A firewall is usually configured based on corporate security policy, and filters incoming and outgoing messages. – To go beyond firewalls, and grant access to world- or Internet-wide resources, end-to-end authentication, privacy, and security (Standards) are needed to allow DSs to function – E. g., techniques are Cryptographic and Authentication – usually implemented at a level above the communication subsystem – Virtual Private Network (VPN) security concept allows intranet-level protection of such features/devices as local routers and secure links to mobile devices ? Mobility – Need wireless to support portable computers and hand-held devices – Wireless links are susceptible to, e. g. , eavesdropping, distortions in medium, out-of-sight/range transmitters/receivers – Current addressing and routing schemes are based on ‘wired’ technologies, which have been adapted and, therefore, not perfect and need extensions? QoS (Quality of Service) – Meeting deadlines and user requirements in transmitting/processing streams of real-time multimedia data – E. g. , QoS requirements: guaranteed bandwidth, timely delivery or bounded latencies, or dynamic readjustments to requirements ? Multicasting – Most transmissions are point-to-point, but several involve one-to-many (either one-to-all – broadcast or selective broadcast – multicast) – Simply sending the same message from one node to several destinations is inefficient – Multicasting technique allows single transmission to multiple destination (simultaneously) by using special addressing scheme 3. Multimedia Transmission and Internetworking Heterogeneous Systems ? Types of Networks – LANs: (confined to smaller, typically, 2. 5km diameter spread) ? higher speed, single medium for interconnection (twisted pair, coax, opt), no routing within ‘segments’ – all point-to-point (from hub), inter-segment connections via switches/hubs, low latency, low error rate ? E. g. , Ethernet, token ring, slotted ring protocols, wired. (1) Ethernet: 1970 with bandwidth of 10Mbps, with extended versions of 100/1000Mbps, lacking latency and bandwidth QoS for DSs: (2) ATM – using frame cells and optical fills the gap but expensive for LAN, newer high-speed Ethernets offer improvement and cost-effective – MANs: (confined to extended, regional area, typically, up to 50km spread) ? Based on high-bandwidth copper and fiber optics for multimedia (audio/video/voice), ? E. g. , technologies: ATM, high-speed Ethernet (IEEE 802. 6 – protocols for MANs), DSL (digital subscriber line) using ATM switches to switch digitized voice over twisted pair @ 0. 25-6Mbps within 1. 5km, cable modem uses coax @ 1. 5Mpbs using analog signaling on TV networks and longer distances than DSL – WANs: (worldwide, lower speeds over sets of varying types of circuits with routers) ? High latency (due to switching and route searching) between 0. 1-0. 5s, signaling speed around 3x105km/s (bounds latency) plus propagation delay (round-trip) of about 0. 2s if using satellite/geostationary dishes; generally slower at 10-100kbps or best 1-2Mbps – Wireless: (connecting portable, wearable devices using access points) ? Common protocol – IEEE 802. 11 (a, b, and now g) (WaveLAN) @ 2-11Mbps (11g’s bandwidth near 54Mbps) over 150m creating a WLANs, some mobiles connected to fixed devices – printers, servers, palmtops to create a WPANs (wireless personal area networks) using IR links or low-powered Bluetooth radio network tech @ 1-2Mbps over 10m. ? Most mobile cell phones use Bluetooth tech. e. g. , European GSM standard and US, mostly, analog-based AMP cellular radio network, atop by CDPD – cellular digital packet data communication system, operating over wider areas at lower speed 9. 6-19. 2kbps.? Tiny screens of mobiles and wearables require a new WAP protocol – Internetworks ? Building open, extendible system for DSs, supporting network heterogeneity, multi-protocol system involving LANs, MANs, WLANs, connected by routers and gateways with layers of software for data and protocol conversions – creating a ‘virtual network’ using underlying physical networks ? E. g. , the Internet using TCP/IP (over several other physical protocols) – Comparisons ? Range of performance characteristics: ? Frequency and types of failures, when used for DS applics? Packet delivery/loss, duplicates (masked at TCP level to guarantee some reliability and transparency to DSs; but may use UDP – faster but less reliable and DS applic’s responsibility to guarantee reliability) Diagram 3. 2 Network Principles †¢ Packet Transmission †¢ Packet transmission superseded telephone/telegraph switched network †¢ Messages are packetized and packets are queued, buffered (in local storage), and transmitted when lines are available using asynchronous transmission protocol †¢ Data Streaming †¢ Multimedia data can’t be packetized due to unpredicted delays. AV data are streamed at higher frequency and bandwidth at continuous flow rate †¢ Delivery of multimedia data to its destination is time-critical / low latency – requiring end-to-end predefined route †¢ E. g. networks: ATM, IPv6 (next generation – will separate ‘steamed’ IP packets at network layer; and use RSVP (resource reserv. protocol) resource/bandwidth prealloc and RTP play-time/time-reqs (real-time transp protocol) at layers 3 & 1, respectively) to work ? Switching Schemes – 4 Kinds of switching methods typically used. – Broadcast – no switching logic, all nodes ‘see’ signals on circuits/cells (e.g. , Ethernet, wireless networks) – Circuit Switching – Interconnected segments of circuits via switches/exchange boxes, e. g. , POTS (Plain Old Telephone System) – Packet Switching – Developed as computing tech advanced with processors and storage spaces using store-and-forward algorithms and computers as switches. Packets are not sent instantaneously, routed on different links, reordered, may be lost, high latency (few msec – msecs). Extension to switch audio/video data brought integration of ‘digitized’ data for computer comm. , telephone services, TV, and radio broadcasting, teleconferencing. – Frame Relay – PS (not instantaneous, just an illusion! ), but FR, which integrates CS and PS techniques, streams smaller packets (53 byte-cells called frames) as bits at processing nodes. E. g. , ATM – Protocols – – Protocols – implemented as pairs of software modules in send/receive nodes, – Specify the sequence of messages for transmission – Specify the format of the data in the messages – Protocols Layers – layered architecture, following the OSI suite – packets are communicated as peer-to-peer transmission but effected vertically across layers by encapsulation method over a physical medium Protocols Suites – The 7-layered architecture of the ISO-OSI †¢ Each layer provides service to the layer above it and extends the service provided by the layer below it †¢ A complete set of protocol layers constitute a suite or stack †¢ Layering simplifies and generalizes the software interface definitions, but costly overhead due to encapsulations and protocol conversions Diagram 3. 3 4. Service Provider Management On the Internet, a management service provider (MSP) is a company that manages information technology services for other companies. For example, a company could hire an MSP to configure and administer its business computers and related systems on a continuing basis, saving the company. An MSP is a service provider that offers system and network management tools and expertise. An MSP typically has its own data center that runs advanced network management software such as HP OpenView or Tivoli. It uses these tools to actively monitor and provide reports on aspects of its customer’s networks, including communication links, network bandwidth, servers, and so on. The MSP may host the customer’s Web servers and application servers at its own site. The services provided by MSPs have been called â€Å"Web telemetry† services. The MSP Association defines MSPs as follows: Management Service Providers deliver information technology (IT) infrastructure management services to multiple customers over a network on a subscription basis. Like Application Service Providers (ASPs), Management Service Providers deliver services via networks that are billed to their clients on a recurring fee basis. Unlike ASPs, which deliver business applications to end users, MSPs deliver system management services to IT departments and other customers who manage their own technology assets. TriActive is an example of an MSP. It provides management and monitoring of PCs, servers, networks, and Web sites from its own NOC (network operations center), which is hosted by Exodus Communications. Exodus ensures that the NOC has fully redundant power, network connectivity, routing, and switching to ensure maximum reliability and integrity. A â€Å"microagent† interacts with customer systems to provide system management. The agent is lightweight and designed for use over the Internet. It acts as a universal agent invoking and managing other agents and programs as required for specific actions. The service is delivered via the Web through a secure Internet portal that lets customers view management information, based on their role in the organization. For example, CIOs can view overall management information while help desk technicians can check call queues, escalations, and open ticket status. Systems analysts can conduct asset inventories and view virus reporting. Objective Systems Integrators is another management service provider that provides software solutions for unified network, service application, and process management. OSI was recently acquired by Agilent Technologies. A list of other MSPs may be found at the MSP Association Web site. Web application and infrastructure monitoring and management have suddenly become critical, yet the tools to do them are lacking. Management service providers (MSP), the latest addition to the current slew of service providers, claim to offer products and services that will oversee your Web operations. Companies staking claims as early MSPs include Candle Corp. in Santa Monica, Calif. ; InteQ Corp. in Burlington, Mass. ; and Nuclio Corp. in Skokie, Ill. What makes MSPs distinctive is that their products and services are provided over the Internet on a subscription basis. That means â€Å"MSPs can achieve economies of scale that companies who license software cannot,† says Christopher Booth, head of technical operations at FreightWise Inc. , a Forth Worth, Texas-based online transportation exchange. Though he declined to say how much his company is paying to use Nuclio’s MSP, Booth did say that the service has been â€Å"very advantageous. † The cost savings that MSPs can pass on may help them catch on with corporate customers. Gartner Group Inc. in Stamford, Conn., estimates that the $90 million MSP market will balloon to more than $3. 25 billion by 2005. 5. Programmable/Cognitive Networks A key strength of the Internet has been to reduce the intelligence within the network to that required placed at strategic places within the network such as at administrative boundaries, or at locations where there is a large mismatch between bandwidth, or where the certain location specific services can be used. Others believe that the entire architecture should be rethought as a computational environment, in which everything can be programmed, and the entire network becomes active. The research in this area is aimed at discovering how viable it is to open up such elements of the communications architecture as the routing table. A fundamental question raised by both the active service and the active network approaches is how to ensure that the shared resource of the network remains safe and is protected from misbehaving programs. Programs can abuse the network by generating packet explosions and can abuse the shared processor by using all the memory and the processor cycles. Worse, they may subvert the working of correct programs so that they too break. If network programmability is going to be available to the application designers, we need to ensure that they do not break things by accident, let alone by intention. Traditional systems approaches to protection are based upon what a program should be able to do, then using runtime checks to ensure that the program doesn’t exceed these bounds. This leads to the sandbox model of protection, as used in Java and enhanced to provide protection for Active Networks. However, there are major problems with this approach. First, each runtime check reduces the performance of the system, increasing the overhead of each use of system resources. Second, it is very difficult to ensure that the protection mechanisms are correct, and cannot be subverted in any way. An alternative approach is to use compile time checks upon what the program is doing. This uses the type system to represent predicates about program functionality and if a program is well-typed, then it proves the program to obey the policies implemented in the type system. This approach has been used to allow users to run programs within the kernel as in Spin, and in protecting access to router functionality in the Switchware project. †¢ To provide a network programming language based on Internet `best effort’ communication. †¢ To provide scaleable high-level communication based on `remote spawn’ from which other communication can be built. †¢ To make use of types as safety properties, to ensure that the safety and security policies of the network are maintained. †¢ To rapidly prototype tools such as compilers and simulators in order to drive the development of the language by examples. Best-effort distributed programming In the Internet, an application transmits a packet, which is sent to the next router on the way to the destination. At this router, the arrival of the packet causes code to run, which calls other code dependent upon the fields in the header of the packet. This code may access and modify local state stored in the router and then copy or create one or more packets to be sent out from the router. These packets are then routed on output links depending upon the destination for each packet, and so on until the packets reach their destination, or are destroyed within the network for whatever reason. In our programming model, we have attempted to replicate this basic structure of packet transmission. In the Internet, the arrival of a packet initiates some thread of control which uses the data within the packet to decide upon the disposition of the packet. In our model, a packet becomes a thread of control, carrying the code to be run and the names or values of any data referenced within that code. When a thread arrives at a Safetynet-aware router or end system, the thread code is instantiated within the runtime and runs within a de_ned scheduling class. The thread of control may call other code to be run on its behalf. The other code is encapsulated within classes, which are either present in the router, or are dynamically loaded from elsewhere. Threads can spawn other threads, either locally or on the next hop to some destination. 6. Design of an Internetwork We will discuss about the networking especially the internetworking. In this case we will need to discuss some topics related with the Internet Infrastructure, Internet routing, domain name and address resolution, internet protocol and the applications. Internet Infrastructure: The Internet backbone is made up of many large networks which interconnect with each other. These large networks are known as Network Service Providers or Naps. Some of the large Naps are UUNet, Cerf Net, IBM, BBN Planet, Sprint Net, PSINet, as well as others. These networks peer with each other to exchange packet traffic. Each NSP is required to connect to three Network Access Points or NAPs. At the NAPs, packet traffic may jump from one NSP’s backbone to another NSP’s backbone. NSPs also interconnect at Metropolitan Area Exchanges or MAEs. MAEs serve the same purpose as the NAPs but are privately owned. NAPs were the original Internet interconnects points. Both NAPs and MAEs are referred to as Internet Exchange Points or IXs. NSPs also sell bandwidth to smaller networks, such as ISPs and smaller bandwidth providers. Below is a picture showing this hierarchical infrastructure. Diagram 4 This is not a true representation of an actual piece of the Internet. Diagram 4 is only meant to demonstrate how the NSPs could interconnect with each other and smaller ISPs. None of the physical network components are shown in Diagram 4 as they are in Diagram 3. This is because a single NSP’s backbone infrastructure is a complex drawing by itself. Most NSPs publish maps of their network infrastructure on their web sites and can be found easily. To draw an actual map of the Internet would be nearly impossible due to its size, complexity, and ever-changing structure. The Internet Routing Working: It is general phenomenon that No computer knows where any of the other computers are, and packets do not get sent to every computer. The information used to get packets to their destinations is contained in routing tables kept by each router connected to the Internet. The Routers are called the packet switches. A router is usually connected between networks to route packets between them. Each router knows about its sub-networks and which IP addresses they use. The router usually doesn’t know what IP addresses are ‘above’ it. Examine Diagram 5 below. The black boxes connecting the backbones are routers. The larger NSP backbones at the top are connected at a NAP. Under them are several sub-networks, and under them, more sub-networks. At the bottom are two local area networks with computers attached. Diagram 5 When a packet arrives at a router, the router examines the IP address put there by the IP protocol layer on the originating computer. The router checks its routing table. If the network containing the IP address is found, the packet is sent to that network. If the network containing the IP address is not found, then the router sends the packet on a default route, usually up the backbone hierarchy to the next router. Hopefully the next router will know where to send the packet. If it does not, again the packet is routed upwards until it reaches a NSP backbone. The routers connected to the NSP backbones hold the largest routing tables and here the packet will be routed to the correct backbone, where it will begin its journey ‘downward’ through smaller and smaller networks until it finds its destination. Domain Names and Address Resolution. But what if you don’t know the IP address of the computer you want to connect to? What if the you need to access a web server referred to as www. anothercomputer. com? How does your web browser know where on the Internet this computer lives? The answer to all these questions is the Domain Name Service or DNS. The DNS is a distributed database which keeps track of computer’s names and their corresponding IP addresses on the Internet. Many computers connected to the Internet host part of the DNS database and the software that allows others to access it. These computers are known as DNS servers. No DNS server contains the entire database; they only contain a subset of it. If a DNS server does not contain the domain name requested by another computer, the DNS server re-directs the requesting computer to another DNS server. Diagram 6 The Domain Name Service is structured as a hierarchy similar to the IP routing hierarchy. The computer requesting a name resolution will be re-directed ‘up’ the hierarchy until a DNS server is found that can resolve the domain name in the request. Figure 6 illustrates a portion of the hierarchy. At the top of the tree are the domain roots. Some of the older, more common domains are seen near the top. What is not shown are the multitude of DNS servers around the world which form the rest of the hierarchy? When an Internet connection is setup (e. g. for a LAN or Dial-Up Networking in Windows), one primary and one or more secondary DNS servers are usually specified as part of the installation. This way, any Internet applications that need domain name resolution will be able to function correctly. For example, when you enter a web address into your web browser, the browser first connects to your primary DNS server. After obtaining the IP address for the domain name you entered, the browser then connects to the target computer and requests the web page you wanted. The Disable DNS in Windows If you’re using Windows 95/NT and access the Internet, you may view your DNS server(s) and even disable them. If you use Dial-Up Networking: Open your Dial-Up Networking window (which can be found in Windows Explorer under your CD-ROM drive and above Network Neighborhood). Right click on your Internet connection and click Properties. Near the bottom of the connection properties window press the TCP/IP Settings†¦ button. If you have a permanent connection to the Internet: Right click on Network Neighborhood and click Properties. Click TCP/IP Properties. Select the DNS Configuration tab at the top. You should now be looking at your DNS servers’ IP addresses. Here you may disable DNS or set your DNS servers to 0. 0. 0. 0. (Write down your DNS servers’ IP addresses first. You will probably have to restart Windows as well. ) Now enter an address into your web browser. The browser won’t be able to resolve the domain name and you will probably get a nasty dialog box explaining that a DNS server couldn’t be found. However, if you enter the corresponding IP address instead of the domain name, the browser will be able to retrieve the desired web page. (Use ping to get the IP address prior to disabling DNS. ) Other Microsoft operating systems are similar. Internet protocols: As hinted to earlier in the section about protocol stacks, one may surmise that there are many protocols that are used on the Internet. This is true; there are many communication protocols required for the Internet to function. These include the TCP and IP protocols, routing protocols, medium access control protocols, application level protocols, etc. The following sections describe some of the more important and commonly used protocols on the Internet. Higher-level protocols are discussed first, followed by lower level protocols. Application Protocols: HTTP and the World Wide Web One of the most commonly used services on the Internet is the World Wide Web (WWW). The application protocol that makes the web work is Hypertext Transfer Protocol or HTTP. Do not confuse this with the Hypertext Markup Language (HTML). HTML is the language used to write web pages. HTTP is the protocol that web browsers and web servers use to communicate with each other over the Internet. It is an application level protocol because it sits on top of the TCP layer in the protocol stack and is used by specific applications to talk to one another. In this case the applications are web browsers and web servers. HTTP is a connectionless text based protocol. Clients (web browsers) send requests to web servers for web elements such as web pages and images. After the request is serviced by a server, the connection between client and server across the Internet is disconnected. A new connection must be made for each request. Most protocols are connection oriented. This means that the two computers communicating with each other keep the connection open over the Internet. HTTP does not however. Before an HTTP request can be made by a client, a new connection must be made to the server. When you type a URL into a web browser, this is what happens: If the URL contains a domain name, the browser first connects to a domain name server and retrieves the corresponding IP address for the web server. The web browser connects to the web server and sends an HTTP request (via the protocol stack) for the desired web page. The web server receives the request and checks for the desired page. If the page exists, the web server sends it. If the server cannot find the requested page, it will send an HTTP 404 error message. (404 mean ‘Page Not Found’ as anyone who has surfed the web probably knows. ) The web browser receives the page back and the connection is closed. The browser then parses through the page and looks for other page elements it needs to complete the web page. These usually include images, applets, etc. For each element needed, the browser makes additional connections and HTTP requests to the server for each element. When the browser has finished loading all images, applets, etc.the page will be completely loaded in the browser window. Retrieving a Web Page Using HTTP: Telnet is a remote terminal service used on the Internet. Its use has declined lately, but it is a very useful tool to study the Internet. In Windows find the default telnet program. It may be located in the Windows directory named telnet. exe. When opened, pull down the Terminal menu and select Preferences. In the preferences window, check Local Echo. (This is so you can see your HTTP request when you type it. ) Now pull down the Connection menu and select Remote System. Enter www. google. com for the Host Name and 80 for the Port. (Web servers usually listen on port 80 by default. ) Press Connect. Now type GET / HTTP/1. 0 And press Enter twice. This is a simple HTTP request to a web server for its root page. You should see a web page flash by and then a dialog box should pop up to tell you the connection was lost. If you’d like to save the retrieved page, turn on logging in the Telnet program. You may then browse through the web page and see the HTML that was used to write it. Most Internet protocols are specified by Internet documents known as a Request for Comments or RFCs. RFCs may be found at several locations on the Internet. See the Resources section below for appropriate URL’s. HTTP version 1. 0 is specified by RFC 1945. Application Protocols: SMTP and Electronic Mail: Another commonly used Internet service is electronic mail. E-mail uses an application level protocol called Simple Mail Transfer Protocol or SMTP. SMTP is also a text-based protocol, but unlike HTTP, SMTP is connection oriented. SMTP is also more complicated than HTTP. There are many more commands and considerations in SMTP than there are in HTTP. When you open your mail client to read your e-mail, this is what typically happens: The mail client (Netscape Mail, Lotus Notes, Microsoft Outlook, etc.) opens a connection to its default mail server. The mail server’s IP address or domain name is typically setup when the mail client is installed. The mail server will always transmit the first message to identify itself. The client will send an SMTP HELO command to which the server will respond with a 250 OK message. Depending on whether the client is checking mail, sending mail, etc. the appropriate SMTP commands will be sent to the server, which will respond accordingly. This request/response transaction will continue until the client sends an SMTP QUIT command. The server will then say goodbye and the connection will be closed. Transmission Control Protocol: Under the application layer in the protocol stack is the TCP layer. When applications open a connection to another computer on the Internet, the messages they send (using a specific application layer protocol) get passed down the stack to the TCP layer. TCP is responsible for routing application protocols to the correct application on the destination computer. To accomplish this, port numbers are used. Ports can be thought of as separate channels on each computer. For example, you can surf the web while reading e-mail. This is because these two applications (the web browser and the mail clien.
