Effect of privatization on performance of public corporations

Effect of privatization on performance of public corporations Stock exchanges anywhere in the world provide a platform for investors and capital raisers to come together and get what they want. They assist in trading of stocks and bonds. Apart from that, it can be viewed as a liquidity providing platform. For this purpose, the stock exchange has to have a set of rules that will govern the execution and clearing of trade. Some of the responsibilities of a stock exchange are also enforcing standard rules to reduce transaction costs and monitoring of the trading to prevent manipulations like insider trading. A share or stock company model does issue shares of stock that are available through one or more stock market exchange. Shareholders purchase the shares of stock and become part owners in the company. This is a highly desirable status for many companies, as it can help generate significant amounts of revenue that make it possible for the company to grow in ways that would not be possible if the corporation remained privately held. Etukudo (2002) notes that capital markets transfer funds from savers to investors in productive assets such as plant and machinery as well as to providers of services. Capital markets also provide a mutually beneficial bridge between those who have short-time horizons and companies and projects with longer prospects. In addition, enterprises are provided with equity capital through the stock market, short, medium and long-term debt is made available through the bond market, and short or medium-term debt is provided through the banking sector. The financial intermediaries in all these transactions constitute the financial service sector and while the constituents of the sector and their relative importance vary from country to country, they generally include banks, stock exchanges, brokers and insurance companies. 1.1.1.2 Privatization of public corporations Boubakri and Cosset (1994) note that privatization has turned into a major phenomenon for the developed world as well as the developing world, particularly so over the last decade, with state-owned enterprises (SOEs) being privatized at an increasing rate. Ramamurti, (1991) note that the objectives of privatization are numerous. Country studies show that these objectives include improving government cash flows by redusing subsidies and capital infusions to SOEs, promoting popular capitalism through a wider ownership of shares, restraining the power of trade unions in the public sector, redistributing incomes and rents within society, satisfying foreign donors by reducing the governments role in the economy and especially enhancing the efficiency and the performance of the SOE sector based on the rationale that the private sector outperforms the public sector. Privatization in the 1990s led to the sale of 207 enterprises. Kenya Airways (KQ) was rated the most successful privatization venture in Africa. The Government has earmarked 33 companies for full or partial sale, these include; the National Bank of Kenya (NBK),the Kenya Commercial Bank(KCB), the Kenya Power and Lighting Company (KPLC), KenGen, Kenya Petroleum Refineries, the Kenya Ports Authority (KPA), Telkom Kenya and Kenya Railways Corporation. The methods of sale will range from concessioning, sale at the Nairobi Stock Exchange, and securing strategic partnerships with major players in the relevant sectors. 1.2 Statement of the Problem A study by Boubakri and Cosset (1994) examined the financial and operating performance of newly privatized firms in developing countries and noted that findings in for developing markets could be different from those of developed countries because the capital market may not play its monitoring role. To take account of the possibility that some of the differences between preprivatization and postprivatization performance could be due to economywide factors, the authors used performance measures adjusted for market effects in addition to unadjusted performance measures. The results were generally less significant when they adjusted the performance ratios for market effects. The authors thus concluded that this evidence brings to light the importance of considering a benchmark against which the performance of sample firms can be compared. Limi (2003) studied the influence of the level of economic development on the post-privatization growth rates in public infrastructure within the telecommunications industry and found that although privatization generally spurred network expansion in terms of telephone main lines by 4.4% in medians (5.4% on average), the performance improvement was dependent on the level of economic development. It is only the low-income and lower middle-income countries which can expect a significant positive privatization effect. Thus, it is important to account for economic development in assessing the privatization effects of public infrastructure stocks. From the foregoing it is thus useful to undertake a study to evaluate privatization and performance of public corporations listed in the Nairobi Stock Exchange. 1.3 Purpose of the Study or General Objective The purpose of this study is to evaluate privatization and performance of public corporations listed in the Nairobi Stock Exchange 1.4 Research Questions or Specific Objectives or Hypotheses This study is guided by the following research objectives formulated to aid in gathering the information regarding the research topic. Review literature on privatization of public corporations in Kenya To determine privatization factors in the Nairobi Stock Exchange To analyze privatization implications on public corporation performance in Nairobi Stock Exchange 1.5 Importance or Justification or Rationale of the Study The information generated by this study will be important for stock markets in the East Africa in understanding the implications of privatizing public corporations. This will benefit stock markets in Uganda, Tanzania and wider Eastern Africa which has the stock markets at their infancy stages. It will also assist policy makers who want to make use of performance measures of the stock market in advising public corporations on privatization prospects that may arise when listing in the stock market. In addition, it will guide policy makers of new baselines to use when determining privatization options for public corporations. Educators too in the education industry will find the information obtained from this study beneficial to their curriculum in imparting knowledge to students and researchers who are researching on the sector and how it can greatly benefit the country. 1.6 Scope of the Study The study will be limited to the Nairobi Stock Exchange for the duration 2008-2010. Nairobi Stock Exchange has about fifteen active stock broking firms with fifty two listed companies. I will focus on five of the stockbrokerage firms and fifteen of the listed companies. The use of the listed firms was due primarily to data availability and reliability because they are required by law to provide end of year financial statements. However, firms that were not listed for the entire period under study were left out of the sample. The study used annual reports that are available at the Nairobi Stock Exchange. 1.7 Definition of Terms 1.7.1 Privatization Privatization means the sale of public utilities to private concerns. 1.8 Chapter Summary This chapter covered the background of the research, the problem statement, the purpose of the study or general objectives of this research, the research objectives, the significance and scope of the research i.e. importance of the study and the definitions of Terminologies used in this research. Further, this chapter has specifically pointed the relevance of the study in regards to public corporations, and how they, in a bid to improve performance, employ a privatization strategy in light of global trends. 2.0 Chapter 2: Literature Review 2.1 Introduction This chapter will review relevant literature in line with the study objectives. 2.2 Privatization of Public Corporations in Kenya ROK(1965) noted that the establishment of the parastatals was driven by a national desire to (i) accelerate economic social development; (ii) redress regional economic imbalances; (iii) increase Kenyan Citizens participation in the economy; (iv) promote indigenous entrepreneurship; and (v) promote foreign investments (through joint ventures). This desire was expressed in the Sessional Paper No. 10 of 1965 on African Socialism and its application to planning in Kenya. A comprehensive review of the public enterprises performance was noted by (ROK, 1979) (the Report on the Review of Statutory Boards) that pointed that there was clear evidence of prolonged inefficiency, financial mismanagement, waste and malpractices in many parastatals; and (ROK, 1982) (the Report of the Working Party on Government Expenditures) which concluded that productivity of the state corporations was quite low while at the same time they continued to absorb an excessive portion of the budget, becoming a principal cause of long-term fiscal problem. The enactment of the State Corporations Act was a major attempt to streamline the management of the state corporations. The performance of most of the corporations continued to deteriorate due to the continued reliance on limited public sector financing. Sessional Paper No.4 of 1991 on Development and Employment in Kenya underlined the need to implement privatization and divestiture of State corporations urgently in view of the managerial problems afflicting the parastatals leading to poor return on government investments, the existence of a larger pool of qualified manpower, availability of more indigenous entrepreneurship to permit private sector led economy and the need for non-tax revenue for the Government. The Programme began in July 1992 with the issuance of the Policy Paper on Public Enterprises Reform and Privatization which pointed out that there were 240 commercial public enterprises with public sector equity participation and classified the PEs in to two categories: (i) 207 Non strategic commercial public enterprises which were to be privatised and 33 Strategic Commercial public enterprises which were to be restructured and retained under public sector ownership and control. By the time the first phase of the programme ca me to an end in 2000, most of the non-strategic commercial enterprises had either been fully or partially privatized, liquidated, sold under receivership while the strategic commercial enterprises to be retained under government operation had been reduced to 15 and later to 14 enterprises. The following is a list of privatized public enterprises by PUBLIC FLOATATIONS- Bamburi Portland Cement Co. Ltd, E.A., CMC Holdings Oxygen Ltd, National Bank of Kenya, Kenya Airways, Mumias Sugar Company; by PARTIAL DIVESTITUTRES Kenya Commercial Bank Ltd, Uchumi Supermarkets Ltd, General Motors (K) Ltd, and Housing Finance Company of Kenya. 2.3 Privatization Factors in the Nairobi Stock Exchange 2.3.1 Methods of privatization The term privatization has been applied to three different methods of increasing the activity of the private sector in providing public services: 1) private sector choice, financing, and production of a service;2) public-sector choice and financing with private sector production of the service selected; 3) and deregulation of private firms providing services. In the first case, the entire responsibility for a service is transferred from the public sector to the private sector, and individual consumers select and purchase the amount of services they desire from private providers. For example, solid-waste collection is provided by private firms in some communities. The third form of privatization means that government reduces or eliminates the regulatory restrictions imposed on private firms providing specific services. The second version of privatization refers to joint activity of the public and private sectors in providing services. In this case, consumers select and pay for the quantity and type of service desired through government, which then contracts with private firms to produce the desired amount and category of service. Although the government provides for the service, a private firm carries out the actual execution of it. The government determines the service level and pays the amount specified in the contract, but leaves decisions about production decisions to the private firm. 2.3.2 Advantages and Disadvantages of Privatization Etukudo (2002) sates that in sub-Saharan African countries with a high level of illiteracy, public offer for sale of state-owned enterprises has its limitations due to cumbersome formalities in the prospectus as well as complicated application forms, etc. As banking facilities are concentrated in urban centres, the use of public offer in privatization works to the disadvantage of those in rural areas with few banking facilities. On the whole, Etukudo (2002 contends that privatization programmes have led to marked increases in stock market capitalization as well as increases in the quantity and range of issues traded on the market. The stock exchange has attracted a considerable number of players to the market leading to increased competition within the capital market. The structure and function of capital markets affect the availability of capital, influence investment processes and also influence the ways in which business managers who approach investors project the current performance and future potential of their enterprises. 2.4 Privatization implications on public corporation performance in Nairobi Stock Exchange Yarrow (1986) notes that as firms move from public to private ownership, their profitability should increase. First, given that shareholders wish the firm to maximize profit, newly privatized firms managers should place greater emphasis on profit goals Second, privatization typically transfers both control rights and cash flow rights to the managers who then show a greater interest for profits and efficiency relative to pleasing the government with higher output or employment (Boycko, Shleifer and Vishny, 1993). In addition, Boycko, Shleifer and Vishny (1993) state that following privatization; firms should employ their human, financial and technological resources more efficiently because of a greater stress on profit goals and a reduction of government subsidies. Megginson, Nash and van Randenborgh (1994) note that governments expect that greater emphasis on efficiency will lead the newly privatized firm to increase its capital investment spending. Once privatized, the firm should also increase its capital expenditures because it has greater access to private debt and equity markets and it will have more incentives to invest in growth opportunities. Megginson et al (1994) believe the switch from public to private ownership should lead to a decrease in the proportion of debt in the capital structure because with the end of government debt guarantees the firms cost of borrowing will increase and because the firm has a new access to public equity markets. The authors further note that with privatization, dividend payments should increase because unlike governments private investors generally demand dividends and dividend payments are a classic response to the atomized ownership structure which most privatization programs led to. In terms of output Megginson, Nash and van Randenborgh (1994) contend that privatization should increase output because of greater competition, better incentives and more flexible financing opportunities. On the other hand Boycko, Shleifer and Vishny (1993) predicts a fall in output since the government no longer subsidizes the newly privatized firm to maintain inefficiently high output levels. Kikeri, Nellis and Shirley (1992) assert that governments expect the level of employment to decline once the SOE which is usually overstaffed turns out private and no longer receives government subsidies. However, in growing sectors, the newly privatized firm could absorb surplus labor through new capital investment and more productive use of existing assets. 2.5 Empirical experience Jones, Jammal Gokgur (1999) undertook an impact study applied to 81 privatizations (covering not just infrastructure firms but a range of firms already operating in competitive markets (in agriculture, agro-industries, tradable and non-tradable sectors) in Cote dIvoire and concluded that firms performed better after privatization and that they performed better than they would have had they remained under public ownership. The study also found that the set of transactions as a whole contributed positively to economic welfare, with annual net welfare benefits equivalent to about 25% of pre-divestiture sales. These results stemmed from a number of effects, including increases in output, investment, labor productivity, and intermediate-input productivity. 2.5 Chapter summary The chapter highlighted the different studies that sought to address the research gap. Chapter three will point out the methodology to be used in the study. Chapter 3: Research Methodology 3.1 Introduction This chapter will discuss the research methodology that will be used as the basis of this study. The chapter will also discuss the population of study, sample frame and sampling techniques, data collection methods as well as data analysis and data presentation methods to be employed in the study. 3.2 Research Design The research design employed in this study will be empirical in nature and will be aimed at delivering answers to the research questions outlined in the problem statement. 3.3 Population and Sampling Design 3.3.1 Population The population involved in the study are four privatized public corporation that have listed on the NSE. Population refers to the entire group of people, events, or things of interest that the researcher wishes to investigate. Population forms a basis from which the sample or subjects for the study is drawn. 3.3.2 Sampling Design and Sample Size Methods that we will use in our paper to analyze the operating and market performance are descriptive statistics for evaluating the post listing share price performance and the financial ratio analysis using the accounting data to evaluate public corporation performance as well as their risk and return relationships profile. Documents will collected from the organizations resource center, individual file record, libraries of various universities, company reports, company newsletter and other printed materials (e.g. newspaper cuttings, journals, text books, conference reports, articles, training packages) that were made available for the purpose of the research. 3.4 Data Collection Methods In order to achieve the set objectives, I will collect data from the Nairobi stock exchange database and from the financial statements of the individual companies under study. The collected data will be captured in form of tables. This will be used to capture performance of privatized public corporations listed on the Nairobi Stock Exchange. 3.5 Research Procedures 3.6 Data Analysis Methods This study will use the quantitative method of data analysis. The quantitative analysis is applied using descriptive statistics. According to Denscombe (1998) descriptive statistics involves a process of transforming a mass of raw data into tables, charts, with frequency distribution and percentages which are a vital part of making sense of the data. Data will be analyzed using Statistical Package for Social Sciences (SPSS) program and presented using tables and pie charts to give a clear picture of the research findings at a glance. 3.7 Chapter Summary The chapter describes the methodology that is to be used in carrying out the study. The chapter has also indicated that, data will be analyzed using SPSS and presented in inform of chart and tables. The next chapter will present the findings of the research.

The Simpsons: Appealing to the Middle-Class :: Composition Rhetoric

The Simpsons: Appealing to the Middle-Class For this assignment I watched the show The Simpsons, which comes on the Fox network on Sunday nights at eight. The show is about an animated nuclear family and their everyday lives. The Simpsons targets the middle class families that live in the suburbs of America. The show mainly appeals to families that composed of parents who work at blue-collar jobs and have children, between the ages of 10-18. You can tell this from the commercials, how The Simpsons life style is portrayed and the jokes contained in the show. The commercials seen along side the Simpsons apply to the middle class family. These commercials are meant for both the adults and the children who watch the Simpsons. One such commercial is for Toys R Us. The commercial shows a mom and dad taking their son to the local Toys R Us. Inside the store we get shots of the newest toys to appeal to the kids who are watching the commercial. The commercial then states that it has the most toys for the lowest price. This statement is meant to appeal to the parents who have a low income and can only buy toys that are inexpensive. Among other commercials that are viewed during The Simpsons are family vacation advertisements. One such one is of a family going to Disney world. The commercials states that Disney world has everything for everyone in the family. The advertisement shows the Dad playing golf, which is meant to appeal to the dads who watch the Simpsons. The commercial also shows the mom buying something at the gift shop, which is meant to appeal to the moms who watch the show. And finally the commercial shows the children going on the rides, which is meant to appeal to the kids who watch the show. Another commercial seen with The Simpsons is a commercial for a mini van. In this commercial the mini van is compared to a standard two-door car. The commercial asks, 'How are you going to fit your family in that two-door car';? This commercial is meant to appeal to people who have a large family that needs all that extra space only a mini van can provide. Also the min van comes equipped with a small T.V, and shows kids watching it. This is meant to appeal to children who now instead of just sitting there can watch TV on long trips.

Flawless Use of Parallelism in Shakespeares King Lear :: King Lear essays

Flawless Use of Parallelism in King Lear      Ã‚   Many twists and turns characterize the television soap operas of today. Subplots are a distinctive trait of these daylight dramas, for they keep audience on the edge of their seats. Subplots keep the material fresh and the audience wanting more. Shakespeare uses secondary plots as a literary device to greatly dramatize the action of the play and to spark a contrast to his underlying themes in King Lear. The secondary plots can incalculably improve the effect of dramatic irony and suspense. The effective usage of subplots in King Lear, as a form of parallelism, exhibits analogous traits of prominent characters. Using such literary device permits the audience to understand the emotions of the essential characters in the play. The magnificent similarity of different plots and characters can illustrate Shakespeare's perfect use of parallelism in King Lear.    Parallelism is greatly enhanced by the use of subplots, for it creates emphasis and suspense. The parallel between Lear and Gloucester displayed in the play cannot possibly be accidental. The subplot of Gloucester corresponds the major plot of Lear. The two fathers have their own loyal legitimate child, and their own evil and disloyal kin. Gloucester and Lear are both honorable men, who have children that return to them in their time of need, and are sightless to the truth. Like Lear, Gloucester is tormented, and his favored child recovers his life; he is tended and healed by the child whom he has wronged. Their sufferings are traceable to their extreme folly and injustice, and to a selfish pursuit of their pleasure. In the early beginning of King Lear, Cordelia says that her love for her father is the love between father and daughter, no more, no less.    "Unhappy that I am, I cannot heave My heart into my mouth: I love your majesty According to my bond; nor more nor less." (Shakespeare.I.i.93-95)    In response, Lear flies into a rage, disowns Cordelia, and divides her share of the kingdom between her two unworthy sisters. Such folly and injustice is encountered by Gloucester in the secondary plot.    "O villain, villain! His very opinion in the letter. Abhorred villain, unnatural, detested, brut- ish villain; worse than brutish! Go, sirrah, seek him. I'll apprehend him. Abominable villain! Where is he?" (I.ii.80-84)

A Society of Unequal’s Just Won’t Do Essay -- Literary Analysis, Jan

Everyone has the right to govern oneself in how to act, where to live, and who to associate with. In Jane Eyre, Jane is controlled and structured by an underlying social and economic critique of conventional patriarchal authority. First, we will examine the various patriarchs that Jane encounters with John Reed, Mr. Brocklehurst, Mr. Rochester, and St. John. Then, we can turn our attention to the economics of social class and how Jane conducts herself where she resides rather it be at Gateshead, Lowood or Thornfield and then we will look at how Jane becomes an equal. Upon receiving a vast fortune from her uncle, Jane abandons her role of inferiority and travels to Ferndean to reunite with Rochester as equals. Jane Eyre’s mother decided to marry into a lower social class than her own and consequently did not inherit any of her family’s wealth. John Reed, Jane’s maternal cousin, however did inherit the family’s wealth and therefore thought he was superior to Jane. John made it apparent that his position as sole male heir gives him absolute power to harass his dependent female cousin. One can see this when he finds her hidden behind curtains reading a book, John Reed tells Jane, â€Å"You are a dependent, mama says; you have no money; your father left you none; you ought to beg, and not live here with gentlemen’s children like us†¦I’ll teach you to rummage my book-shelves: for they are mine; all the house belongs to me† (Bronte 23). John then proceeds to demand Jane to go and stand by the door, which she complied to because she is considered his inferior. John then threw the book that he found Jane reading at her. She fell and struck her head against the door, causing it to bleed. Jane verbally lashes out against John Reed, and ... ...ction, Volume 31, No. 4. (March 1977) 397-420 JSTOR. Web. 11 Nov. 2011. .

A Pleasurable and Educational Preschool Observation Essay

I observed a 4 year old preschool class during playtime in Staten Island, New York. The class consisted of eight children, and one certified preschool teacher. There were 4 boys and 4 girls in the class. During my sixty minute observation I noticed several instances of dramatic play, peer relationships, relationships with adults, and self-control. Dramatic Play During my observation, I witnessed a group of two- one boy and one girl-playing house. According to Hutchinson (2011) children often use playing house as an opportunity to explore reality and their social roles based on adult behavior. The two children that I observed explored reality and their social roles as they pretended to eat dinner together as family. The pair even took it a step further as they included doll babies to play as their children. As the children played house, the girl cooked dinner and the boy sat at the table waiting for dinner to be ready. As the boy waited for dinner to be ready, he got up, walked around as if he was looking for something and came back with two baby dolls and told the girl, â€Å"here they can sit next to you†. The boy had assigned the girl a perceived female role, to be the mother and care for the baby. While the girl had assigned herself a female role, to cook for the male. Therefore, the boy was automatically assigned a perceived male role, to wait for the female to finish cooking so he could eat. The pair’s dramatic play demonstrates how children begin to understand standard gender roles and play accordingly during early childhood (Hutchinson, 2011). This play interaction was not gender segregated. This non-gender segregated play is a good example of how children play based on their gender. Although, many young children prefer to play with same sex mates, I believe this was not the case because the pair felt playing house required a female and male to fit the correct gender roles. I also believe that mass media plays a strong role in the way preschool children play in their perceived gender roles. According to Kirkorian, Wartella and Anderson (2008), by preschool age children are active television viewers. Therefore, if children watch shows that are based on family life, such as Modern Family, they will notice a strong presence of women in the kitchen and  caring for children, and model similar behaviors. Relationships with Adults During my observation there was little interaction with the teacher. Children seemed to prefer to play with their peers. One teacher-student interaction I observed was a withdrawal relationship. The teacher tried to engage the pair of preschoolers playing house. However, her engagement was unsuccessful. The teacher walked over to the pair’s play station and asked about the babies’ names. The pair answered the teacher but did not engage other than answering the question. During the time the teacher was questioning the pair, the girl got up from the play dinner table and walked over to play with another group, a group of girls. This example supports Garvey (1990) and Harper and McCluskey (2003) argument that the attention of an adult or teacher may hinder children’s peer interactions. The girl’s reaction to the teacher disrupting her play scenario was withdrawal. Another teacher-student interaction I observed was a friendly interaction. The teacher engaged a boy who was with trucks in play. During this interaction, the boy was playing alone with cars and trucks. The teacher asked if she could play with him, and he agreed. The teacher and student then played with cars and trucks in a friendly manner. This is normal as there is a tendency for teachers to spend more time with children who are less social than more social children (Harper and McCluskey, 2003). The boy in this case could be perceived as less social than others as he played alone the entire hour. During my observation I did not see attachment-seeking behavior from the children towards the adults. However. I did have the chance to observe one preschool girl dropped off by her mother prior to my observation. The preschool girl’s behavior was fussy and aggressive. The girl cried and kicked while the mother signed the girl in. The mom tried to soothe the girl, but looked like she needed soothing herself. Generally, separation from mothers can be stressful for children, however, separation from children can also be stressful for mothers (Balaban et al., 2002). Peer Relationship One peer relationship I observed consisted of three girls playing dress-up. Unlike the previous pair that was not gender segregated, this group of girls was gender segregated. According to Hutchinson (2011) in early childhood, children make friends with other children of the same gender and age. As  these girls engaged in dramatic play they were very nice to each other. They played with each other’s hair, did each other’s make-up, and referred to each other as â€Å"my best friend†. After the forth girl in the class finished playing house with the boy, she approached the three girls and asked if she could play with them. The three girls took the forth girls play initiation as a conflict. The three girls then teamed up and said â€Å"no way, you’re not our friend† to the fourth girl in the class. Young children often use the term friend and playmate interchangeable. According to Hutchinson (2011), young children see the definition of a friend as someone you play with. Therefore, when the fourth girl asked to play with the three girls she was excluded because she played with the boy and was the boy’s friend and not the three girl’s friend. Self-Control During my observation, I witness one instance of aggression. One girl was building a â€Å"princess castle† with building blocks and a boy came by and kicked over the castle. The girl immediately got up and pushed the boy and the boy pushed the girl back. The boy or girl did not show any self-regulation as they engaged in a fight. Also, there was no helpful or empathic prosocial behavior, as the children’s actions did not prevent negative impulses. In this instance of â€Å"self-control† or lack of self-control, the boy and the girl exhibited both instrumental aggression, fighting over toys and physical aggression, physical force against someone. However, these form of aggression is normal for preschool aged children as aggression increases during early childhood years (Hutchinson, 2011). Fortunately, aggressive behaviors normally deteriorate by the end of early childhood as children learn to better communicate their needs (Hutchinson, 2011). My preschool observation was a pleasurable experience. I was able to watch eight happy children play, fight, laugh, and joke with each other. My observation was also an educational experience as I was able to apply theories learned in class to real life situations. Overall, my observation experience was both enjoyable and educational.

Racism in Canada Essay

Canada is know around the world as an world-wide peacekeeper, a place of liberty, and a winning coun shew that combines perpetu every in allyy unrivalled. This re draw upation is part of our image, and is honoured by many nations. But Canada is non perfect. racial discrimination still exists, rough cartridge clips it maybe in the shadows, it does not take a investigative detective to notice the visible racism all around us. In some cases it is social phrases, in some it may be serious bullying, discrimination or even assault, racism is still a problem.Like the United States of America, Canada has a news report with racism. In the 1900s to 1950s, there was discrimination against African-Canadians. From the time of settlement into North America, up until a few decades ago, there was serious mis-treatment of offset printing Nation flocks, including genocide, sexual assault and chela a tutore. Also during WW2, Japanese-Canadians were looked upon as enemies, and treated poo rly. Comp ard to the past(a), we atomic number 18 much more liberal, and have little racial prejudices.The improvement of polite liberties from the past to now is amazing. But still not enough. Every time I catch something racist, it deeply saddens me. In my heart, Canada as a whole has left racism behind, just some people still ladder the disgusting tradition. I once maxim a bus driver utterance disrespectfully to an older Chinese woman, or so how he couldnt understand her, and she should try to speak in English. I horizon to my self how sad it is that an official metropolis worker can be so intolerant of other cultures.I do not like racism, and check up on it a lot. I see racism when a group of African-Canadians attack a whiteness man for coming to the wrong vicinity. I see racism when people say, White people cannot play cricket, when some of the best cricket players are Caucasian, like Alastair Cook, with over 8000 runsscored. I see racism in stereotypes. It is cle ar that racism is a part of our society now, just now we need to improve our selves and eradicate it for good.To extinguish racism completely, we first need to dumbfound personal feelings aside, and agree on facts. Yes, we are all humans. But we need to accept our differences, we are not the exact same. peculiar(prenominal) genotype gives athletes like Bolt a boost, dailymail reports scientific research through with(p) by University of Szczecin in Poland. Once we crumble fact from fiction, we can live without delusion. Secondly, we must call out racism when ever we see it, for example if a bus driver does something wrong, he should be confronted, to evacuate it from happening again. If we call out all racism when we see it, we can put an end to it.In conclusion Canada is one of the best countries to live in in the world. It is a leader in civil rights, peacekeeping, and equality. However some racism clay in our community from the past, which should be cleaned up. If we all aim towards a better future, the surrender could looked upon in future similarly to how the bloody 50s are seen today.

Improved Fast Decoupled Power Flow

The index flow compend is a very important and tundamental tool in power schema analysis. Its results play the major role during the operational stages of every body for its suss off and economic schedule, as surface as during expansion and design stages The purpose of every load flow analysis is to compute punctilious steady-state electric potentials and electric potential burdens of tout ensemble private instructores in the ne iirk, the objective and activated power flows into every strain and transformer, under the arrogance of known generation and load.During the second half of the 20th century, and after the monstrous technological evelopments in the handle of digital computers and high-level programming talking tos, many methods for settlement the load flow problem have been developed, such as indirect Gauss-Siedel ( tutor admittance intercellular substance). direct Gauss-Siedel ( quite a little ohmic resistance intercellular substance).Newton-Raphson (NR) and its decoupled versions Nowadays, many Improvements have been added to in all in all these methods involving assumptions and approximations of the transmission lines and busbar information, base on real systems rails The unfaltering Decoupled mogul Flow system (FDPFM) is wizard of these rectifyd methods, which was based on a simplification of the Newton-Raphson method and describe by Stott and Alsac in 19744. This method and due to its calculations simplifications, lush adjoinnce and reliable results became the intimately widely utilise method in load flow analysis.However, FDPFM for both(prenominal) cases, where high RA ratios or heavy fill up (Low Voltage) at some buses argon present, does not converge well. For these cases, many efforts and developments have been made to overcome these overlap obstacles. some of them targeted the intersection of systems with hgh RIX ratios, others those with low electric potential buses However, single of the most rec ent developments is a Robust Fast Decoupled Power Flow developed by Wang and u it Is ased on heuristic justification and general potential normalization methods 171 and solves both high RIX ratios and low bus potential differences problems simultaneously.Though many efforts and elaborations have been achieved in order to improve the and simulations atomic figure of speech 18 becoming more than developed and are now able to handle and analyze large surface system. Today, and after r to for each one oneing processors do-nothingnonball alongs higher than 3 GHz, any improvement in the speed of convergency of the power flow method, provided it channels to reliable results, is of great value. This speed improvement is very important when baffling in operational stages of power distribution, where any illisecond preservation can hugely affix the probability of the right decision, of the control and dispatch computerized system.This paper works on providing reason bringings (in flops) and so higher speed of crossroad of the FDPFM based on the initial approximation in which real power changes are considered to be most sensitive to variations in voltage angle and very practically less(prenominal) to those of voltage order, as well as on the high sensitivity of reactive power changes to variations in voltage magnitude and much less to those of voltage angle. In this paper, the attention was focused on the update of the voltage angle (6) and oltage magnitude (V) in each iteration, based on the improvement of flops achieved, and plain on the results obtained.The results of these improvements and the comparative analysis with the Newton-Raphson and classical FDPFM provide be presented using the triad IEEE bus systems of 14, 30 and 57-bus, although the IFDPFM can be applied to any size bus system. II. Fast Decoupled Power Flow Method As the FDPFM is derived from the Newton-Raphson we pass on start from the intercellular substance means of NR, chi p in some simplifications and approximations, to overturn the equations of the FDPFM.The matrix theatrical work of the N-R method 17 is O APOOH Where I IVJI IYiJl +6) And -2 romaine lettuce microchip +2 cos -6i +6) Nii = I VI II YiJ I cos (B iJ- 6i + 6) Nil (7) -2 IYiil stn +2 IVJI IYiJl cos -6i +6) Now, for typical power system branches XIR and 200 (10) in the midst of AQ and A6, hence N and J entries of the initial matrix of (1) can be ignored leading to the pastime decoupled equations (12) Now, the precin one caseption elements of H according to Stott and Alsac 4 can be scripted as IVi12Bii (13) Where Bii = I Yill sin Bii is the conceptional part of the diagonal elements of the bus admittance matrix Ybus.Further simplifications can be applied to equation (12), by considering Bii Qi and I Vil 2 z I Vil yielding to the following simplified Hit Hii=- (14) Also, as under normal operating conditions 6 6i is quite small, thus Bii 6i + 6 Bit, and IVJI 1, the off-diagonal el ements of the matrix H can be written as HIJ I Vil (15) Similarly, the diagonal elements of the L matrix can be written as Lil (16) And its off- diagonal elements as LiJ=-lVll (17) Applying these assumptions to equations (11) and (12) we get =-BA6 I vil (18) (19) where B and B are the imaginary part of the bus admittance matrix Ybus , such thatB contains all buses admittances except those related to the quench bus, and B is B deprived from all voltage-controlled buses related admittances. Finally, all these approximations and simplifications lead to the following successive voltage magnitude and voltage angle modify equations (20) IVI (21) These equations formed the rump of the iteration scheme upon which the Matlab software written and because updated. Ill.Updated Algorithm The algorithmic programic program written according to the equations derived in the previous section is as follows look 1 initiation of the bus admittance Ybus according to the lines data given y the IEEE standard bus ladder systems. Step 2 Detection of all kinds and verse of buses according to the bus data given by the IEEE standard bus test systems, setting all bus voltages to an initial value of 1 pu, all voltage angles to O, and the iteration dealer iter to O.Step 3 Creation of the matrices B and B according to equations (18) and (19). Step 4 If exclusive (AP, AQ) accuracy thus Go to Step 6 else 1. weighing of the H and L elements of equations (14), (1 5), (16), (17). 2. Calculation of the real and reactive power at each bus, and checking if Mvar of root buses re within the limits, otherwise update the voltage magnitude at these buses by ?2 3. Calculation of the power residuals, AP and AQ. 4.Calculation of the bus voltage and voltage angle updates AV and A6 according to equations (19) and (20). 5. Update of the voltage magnitude V and the voltage angle 6 at each bus. 6. Increment of the iteration counter iter = iter + 1 thus Go to Step 4 ingrain out Solution did not con verge and go to Step 6 Step 6 Print out of the power flow solution, computation and display of the line flow and losses. The update of this algorithm was based on the weak coupling surrounded by AP and AV, nd amid AQ and A6, explained in the previous section.Specifically, in the ivth office of Step 4 of the initial algorithm, and instead of modify the voltage magnitude and the voltage angle once and simultaneously in each iteration, the improved algorithm updated either the voltage angle or the voltage magnitude at each bus, Jumped to subroutine 1 to recalculate the real and reactive power and then updated the second variable based on what was updated rootage.Moreover, and for more speed improvements and convergence reliability, the update of one of the both variables was repeated several clock, holding the other ariable at its last calculated value, which reduced the proceeds of afloat(p) baksheesh operations of the algorithm and thus lead to the faster convergence of th e IFDPFM. IV. Numerical Analysis The performance of the IFDPFM was tested on IEEE 14, 30 and 57-bus systems with a convergence accuracy of 10-3 on a MVA base of nose candy or equivalently 10-1 MVA for both power residuals AP and AQ.This numerical analysis involved a speed comparison amidst the NR method, the FDPFM and the IFDPFM based on the government issue of flops (floating point operations) of each algorithm implementing each method, rather than on any other basis, because he flops count is independent from the central processor speed or the specific programming language used. In addition, as mentioned in the previous part, the algorithm of this paper updated the voltage angle several times before updating the voltage magnitude or vice versa which resulted in a antithetic flops count for each combination used for the same IEEE bus system.These combinations will be noted according to the number of loops of update of each variable. For instance, updating twice the voltage ang le (6) and then once the voltage magnitude (V) in the same iteration will be written as (21). Note that any flops number without the previous notation will be the one of the best case of the updated algorithm. Moreover, for any combination to be listed in this paper it should have satisfied the condition of no more than 3 % deviation of its results from that of the NR method.The blank out graph in see to it 1 shows a comparison based on the number of flops between the NR, FDPFM and the best case of IFDPFM for the three IEEE standard bus systems used in this paper. Number of flops per method per system 934. 573 305. 126 314. 925 157. 310 System 57 4,421. 752 2,841. 646 14 30. 823 56. 829 24. 574 1 ,ooo ,500 2,000 2,500 3,000 Flops IFDPFM FDPFM 4,000 4,500 (Thousands) Fig. 1 Flops Comparison between the 3 methods. It is clearly seen that the IFDPFM requires much less flops to converge as compared to FDPFM or NR.This flops saving is proportional to the system size and as shown, incre ases with the increase of the number of buses. Obviously, this improvement in the number of flops will make the IFDPFM converge much faster than the two other methods whatever CPU used. Numerically, and for the biggest system involved in this paper (IEEE 57-Bus System), the IFDPFM revealed a flops saving of or so 67 % when ompared with the FDPFM and about 78 % when compared with the NR.Normally, and as mentioned before, this saving goes down to the order of 50 % for the two little bus systems. In addition, and in order to reach the best case presented above, different strategies of updating the voltage angle (6) and the voltage magnitude (V) were tested and compared first with the FDPFM then with the NR. Figure 2 below the destiny of flops of IFDPFM versus that of the FDPFM, for 10 different updating strategies and for the three IEEE systems.Percentage Flops IFDPFM vs FDPFM 75 50 25 DeltaVoltage Loops IFDPFM14 IFDPFM30 IFDPFM57 Fig. 2 % of flops of IFDPFM vs. FDPFM for different voltage angle and voltage magnitude updating strategies. At the first look, it is seen that for the three systems, three duplicate curves are sketched with most values less then 75 % of the FDPFM. This parallel property of this graph shows the congruity of the algorithm in its number of flops variation for each strategy for each system studied.Also, it is seen that for low number of voltage magnitude and voltage angle loops the IFDPFM cant be more efficient than FDPFM, but for a just about higher number the IFDPFM shows great improvement in flops saving nd reaches the highest improvement at the point (43), where in each iteration, the voltage angle was updated four times while the voltage was unploughed at its initial value and then 6 was kept at its last value and V updated three times.Numerically, and for the best case of IFDPFM (43), the new algorithm showed a flops saving of 57 % for the 14-bus system, 50% for the 30-bus system, and 68% for the 57-bus system. Figure 3 below shows the percentage of flops of IFDPFM versus that of the NR, for 10 different updating strategies and for the three IEEE systems. IFDPFM vs NR 175 150 25 Fig. 3 % of flops of IFDPFM vs. NR for different voltage angle and voltage magnitude updating strategies.Basically, the same comments of the comparison of IFDPFM with FDPFM apply in this comparison. However, here the flops saving is much more significant and is proportional to the system size. Numerically, we have a 21 % flops saving for the 14-bus system, 49 % for the 30-bus system and 78% for the 57-bus system. Finally, it is remarked that when compared with NR, IFDPFM savings showed a high variation in their percentage, mainly because they are highly proportional to the
