The Career Of A Nurse - 1962 Words

According to World Book Encyclopedia, the career of nursing has advanced throughout history. It has developed from the nurse been a housekeeper to a trained professional that could help the sick recover. Nurses in the past never went to a school, they were nuns or other women who provide care for the disadvantaged who had no family support. These women only had knowledge of nursing from what they learned from family and friends. Nurses were not respected in the early days because been a nurse was not consider a reputable career.

My research shows that there are three key figures in the advancement of nursing as we know it today. These pioneers blazed a trail for the women and men of today. They were Florence Nightingale considered the leading founder of nursing, and she was the first to realize the importance of good cleanliness and proper nutrition. Margaret Sanger was the first to fight for a woman’s right to choose birth control she also started the movement to inform women about sex.

The Nature of Child Development Essay - 1172 Words

Human development has been a subject of interest since ancient Greece and Rome. Different approaches derive from two basic directions: the nativists` and empiricists` ones. The latter method is to regard human development as a gradual change which has been influenced by the individual`s experience .On the other hand, the former approach has found its roots in the biological structure of the human organism which considers our development as a series of stages. However, referring to human development only as continuous or gradual would produce inconsistent and insufficient understanding of the developmental process .As a result, combining ideas of both viewpoints(continuity and phases) will provide a more explicit of understanding of the†¦show more content†¦He distinguishes eight psychological crises(stages) which directly relates to the social requirements and emotional bonds. Human psychosocial development is seen as unique which offers a great range of diversity. Consequ ently, this variety provides an opportunity of establishing universally necessary and sufficient phases of development. The eight stages form a circle which demonstrates the similarity between the first stage ( trust vs mistrust) and the last one(integrity vs despair).In other words, the human beings strive for integrity which could be reached only by passing successfully through all the phases which is a lifelong experience. Concluding from this, human development is a continuous process which is constructed by different phases. The stages role is to present more concrete and deeper understanding of this process. Another perspective is also socially orientated but it plays a considerable emphasis on the historically-cultural influences. Lev Vygotsky (1978) also explains human development as a sequence of phases. A greater interest is placed upon the formation of higher psychological processes. As a result, the importance of the language is greater than in any other theory.

Necessity of Diversity Management in CERA-Free-Samples for Students

Question: Discuss about the Necessity of Diversity Management in Cera. Answer: Introduction: Diversity management entails the practice of focusing and supporting multiple cultural and personal lifestyle and characterization within an organization. In any multinational company, there are employees from various cultural and social backgrounds, and it is the responsibility of the management to control and prevent any conflicts aroused in the organization. CERA is one of the global innovative human resource management companies that continuously seeking for growth and by attracting talents from all over the world, which refers to the need for diversity management in the organization. Diversity management is one of the major strategies followed in any multinational organization to support, accept and respect diverse racial, societal, economical, cultural, political and geographical backgrounds. In other way, the diversity management refers to the ability of the management of an organization for managing the personal and cultural differences in the same. The management of the comp any needs to acquire specific skills and knowledge to design the strategies for managing the diversity in the organization. A multinational company may have their branches throughout the world which means to have the employees around the world. The management of the company needs to follow certain strategies to handle employees from different cultural and societal background. In this report the chosen company is CERA, where the diversity management id indeed needed for building a fine and appropriate work environment. However, this has been a subject of debate in the business rationale, but there is severe need for applying diversity management strategies in multinational company like CERA. The following report discusses the necessity of diversity management for adding values to the organization. Determinates of Diversity: In the world of ever changing, dynamic and overly complex social and organizational structure, diversity is one of the major factors that need to be managed efficiently. The infusion of the modernity and the post colonialism into the organization having multicultural perspective has enabled the organization of effective management of the complex and diverse manpower resources in the workplace (Trompenaars Hampden-Turner, 2011). Perception of different researchers and management scholars of diversity is different and can be distinguished as broader and narrower scope of diversity. The broader aspect of the diversity deals with the age, race, ethnicity, gender and spiritual diversification of the people within an organization. Whereas, the narrower aspect of diversity deals with the issues regarding race, sex and class. As per the organizational perspective of diversity, this can be stated that managing the diversity problems within an organization is about recruitment, retention and establishment of proper workplace relationships among the employees belonging to the specific and distinctive cultural backgrounds by eliminating the anti-social and conflicting behavior within the organization. The rapid change of demographical situations in the society as well as the in the organizations has been marked as primary reason for diversity in the organizational workplace. This primary reason requires awareness in the management system for managing the same. The issue of diversity can be different on the basis of country. There are many countries that do not consider the issue of diversity management as the severe one, whereas in many other countries the issue of diversity management is given special and prior attention (Critically Analyze The Diversity Management At Multicultural Organizations Business Essay., 2017). Again, the beneficial aspect of the diversity in the organization refers to the need for rich cultured competent manpower which requires a great effort from the management. The management of the organization is responsible for ensuring the correct and fair treatment for each employees and managing the entire workforce for promoting better rewards in order to add co mpetitive value to the organization (Triana Garcia, 2009). Again, the lower cost advantages achieved through the lower expenditure on the training of the employees highlights one individual occasion while evaluating the value appreciation of diversity (Martins Parsons, 2007). Cultural Aspect: The cultural aspect is one of the major and prime focuses while evaluating the idea of diversity management of any organization. Globalization and the cultural conflicts are internally connected with each other (Ozbilgin Tatli, 2008). Hence, the rate of globalization indicates the cultural issues that can be aroused in an organization (Trompenaars Hampden-Turner, 2011). To understand the issue of diversity and that of its management, one must understand the notion of cultural clashes or the cross-cultural aspect in the multinational workplace. Furthermore, the diversification of culture can be distinguished in several types while discussing the same in the workplace such as managerial cultures, workers culture and the culture of the organization as a whole. The cross-cultural diversity is capable of constituting new dimensions, which can result into the cause of work values and organizational beliefs, communication, competition within the organization, conflicts in decision-making and the authoritative power (Shachaf, 2008). However, the diversity management contains promoting and appreciating different cultural beliefs and values, diminishing discriminations and prejudices and streamlining numerous positive dimensions of diversity in order to ensure healthy and professional relationship, better productivity and the greater workforce outcome (Mujtaba, 2007). The management of the organizations need to be competent and experienced enough to face these challenges and overcome the same. Gender Diversity: Gender diversity is one of the major and prior issues that need proper and delicate handling by the management of the organization, as this issue plays a very vital role in the diversity management. Gender diversity is considered as a potential and prominent cultural factor that causes workplace conflicts and employee turnovers. For example, if the female employees of the do not find much respect and equality in the workplace meeting regarding the business growth, then the eligible and competent female employees may leave the organization. The gender diversity being a prominent factor of cultural architecture is proved by the socialization of the women (Shen et al., 2009). It is found that the women are more capable of handling conflicts in workplace and dealing with ambiguity, which exhibit their flexibility for being better managers than men are. Such situations can cause several vexations to the male employees in the organization such as work depression, lower self-confidence, job insecurity, jealousy for female employees and negative thoughts about women. For example, any female employee, having a background of an ethnic group, is more efficient and eligible for promotion to a manager. The male employees may find it unsatisfactory and suffer from job insecurity which can further results employee turnover. As previously mentioned, the gender segregation gives birth to the cause of personality diversity. Personality of the employees constitutes the entire set of factors affecting the interaction among the employees within the organization (Kearney, Gebert Voelpel, 2009). The Big-Five personality model briefly helps the management to analyze the employee personality by pointing out the major characteristics of a person (Musek, 2007). Implementing the model in the organization for managing the diversity in workplace, can widely differ the reactions of the employees. The employees falling under the model are found more flexible and tolerant towards the workmates depicting their actions and emotions such as sympathy, openness, kindness, helpfulness than others. In other way, employees, who do not fall under this personality model, are capable of projecting negative influence inside the workplace of the organization. Importance of Diversity in Workplace: Despite being several determinates pertaining the diversity within an organization, there is a beneficial aspect of the diversity too. Having diverse workforce within an organization can help to ensure and enhance the business growth. The diverse culture of the workplace can produce multiple beneficial factors for the business. The first and one of the important outcomes of the diversity is the innovation (Talke, Salomo Rost, 2010). An organization having employees from different cultural and societal background can be the cause of innovative business ideas for the organization. The introduction of innovation not only helps the organization to improve their business growth, but also help building a creative culture within the organization. Another importance the diversity of workforce within an organization projects is to attract the external professional talents, stakeholders, and customers (Mujtaba, 2007). One of the popular and effective business magazines states that a business organization, which is authentically diverse both from outside and inside can be successful advancing its business growth. The complementation of the idea of diversity management mentions that any organization that manages the diversity issues within the workplace, is capable of attracting more competent professional from diverse backgrounds. This not only adds value to the competitive business advantages, but also builds a rich work culture within the organization (Kearney, Gebert Voelpel, 2009). There is different definition of cultural diversity (Shachaf, 2008). One group of scholars and researchers perceive the idea of cultural diversification as the belonging of the people to different backgrounds. Whereas, another group of scholars defines the cultural differences as different beliefs acknowledged by different people (Moran, Abramson Moran, 2014). The fact can be foregrounded that increasing globalization and different societies are enabling one to acquire more than one culture at a time. In other way, this can also be stated that the employees learn work culture from the seniors in the organization, whereas, they learn their individual cultural beliefs from their parental cultures (Martins Parsons, 2007). Therefore, this can be said that the diversity in the context of individual culture has various definitions and each is different from each other, which can help the organization to be rich with the culturally intelligent labor, which will further improve the work cu lture as well as the organizational culture. Organizational Values of Diversity Management: Apart from providing challenges in the workplace, the diversity management is also an effective process of adding value to the organization (fbe.unimelb.edu.au., 2017). It is a blessing to the companies having diverse work culture, since this enable them to be armed with numerous i9deas, views and perspectives, which can further strengthen their abilities to design strategies, communicate and render the same. The diversity management also provides opportunities to the employees for innovating creative ideas through interacting with each other. Diversification of the work culture determined by the employees belonging to the different market sectors and demographics help the organization to understand the customer base for their business. In short, the diversity management helps the organization to segment the market for their business, which undoubtedly adds values to the business as well as to the entire organization (Triana Garcia, 2009). Employees having diverse social and cultural backgrounds influence the medium of communication. The different cultures become the reason for different languages, which adds benefits to the organization in communicating with different linguistic stakeholders, vendors and customers. Moreover, the diversity management helps those organizations who practices Corporate Social responsibilities towards the ethnic community, for communicating with the people belonging to the same groups. Precisely, the diversity management of the organization helps developing the linguistic skills for the entire company. As discussed previously, the diversity within the workplace gives birth to the creative and innovative ideas for the improvement of the business. In other way, managing the diversity produces intrapreneur within the organization, which no doubt adds business values to the organization by innovating creative and smart ideas. These not only helps in creating an entrepreneurial atmosphere inside the organization, but also find out new, creative and future talents (Bridgstock et al., 2010). Being enriched with staffs coming from different cultural backgrounds benefits the organization by understanding the market needs. Culturally diverse employees are capable of understanding the different cultural market, which further helps the organization in delivering products according to the market needs. Gender diversity in this case also helps the organization to point out different gender needs and demands and accordingly the organization can improve their productivity. This is how the diversity management of a organization can add values to its business. Necessity of Implementing Diversity Management in CERA: CERA, being an international company, possess employees from different cultural and social background, which makes the company to have a multicultural workforce (Ozbilgin Tatli, 2008). The HR of the organization must implement the diversity management in order to avoid the workplace conflicts and ensure the value addition to the business. As discussed in the previous section of the report that the diversity management is an important and value adding factor for the organization. Similarly, foe CERA the diversity management is necessary to improve the business growth by understanding the different market segmentation as well as the customer needs. The HR of the company must understand and realize the necessity of implementing the diversity management in the organization. CERA has a global market and branches in most of the countries throughout the world. In addition, the organization possesses international market, which is categorized by different cultures. Therefore, the employees of the company are also enriched with diverse cultural traits, beliefs and practices. Having a vast range of cultural employees, the implementation of the diversity management is indeed needed for the company. the diversity management of the company will help the CERA to promote and appreciate different cultural intelligence and practices, which will encourage the employees to improve the productivity of the company. For example, if the company has any employees who belongs to any ethnic group, he can understand the customer demands and needs for particularly to that group. Hiring people from different cultural background can also help the company in advancing their business to the new area, which can be effective in terms of adding business values to the organization. Recruiting staffs from diverse background can also provide opportunities to identify new stakeholders from diverse ethnic groups. Again, being a global business company, the prevalence of the gender diversity needs to be managed. The gender diversity management can help the company to understand the gender based needs and design business strategies accordingly. This need to be mentioned in this regard, the management of the gender diversity needs to be done delicately, since this issue can create conflicts in the workplace. Moreover, the diversity management within the workplace of CERA will produce effective result by attracting more efficient and professional talents from the diverse cultural backgrounds (Shen et al., 2009). This will, no doubt help the organization adding values to the global business and achieve competitive advantages. Conclusion: Therefore, this can be concluded from the above discourse that the diversity management is one of the major factors that determine the value addition of the organization in terms of global business. The diversity management refers to the management of the diverse culture present in the company due to various cultural people from diverse backgrounds. There are several determinates that cause the diversity within an organization. However, the diversity in the workplace can be beneficial to the organization as it adds values to the organizations business. The importance of the diversity management cannot be ignored as it helps a multinational company to improve their business and spread the same. The diversity management includes the innovation, talent acquisition, market segmentation and so many improvements to the organization. For a global company like CERA, it is important to implement the diversity management, because this will not only help the organization to enrich their work cu lture but also will add business value to the company. Diversity management will create opportunities for the new entrepreneurs to produce innovative ideas for the company. This way both the company and the entrepreneurs will be privileged. In addition, the company will be capable of identifying local stakeholders in order to spread the business into the local community. Thus, it is suggested to the HR of the chosen organization, CERA, to implement the diversity management into the organization for overall profit and business growth References: Bridgstock, R., Lettice, F., zbilgin, M.

This difference is very significant as one seems to describe the society more than the other. According to Weber, the society has the social class and the social status or the social honor. On the other hand, Marx describes the social structure of the society as one comprising of the capitalists or the bourgeoisie, the workers or proletariat and the petite bourgeoisie (18). With definitions, Webster’s social structure defines today’s society better. When Marx describes the social structure as one categorized into three groups, he categorizes these groups in economic terms, that is, those willing to buy labor and those willing to sell it. On the other hand, Weber’s structure is both economic and non-economic (religion, prestige and honor). The modern society is more accommodative of Weber’s structure. In an instance, the religion is one that groups people in a society. The Muslims, whether poor or rich, tend to be more social with each other as compared to a rich Muslim man and another rich Christian. It is after categorizing themselves into religions, or other groups that the people further categorize themselves on economic basis. In other circumstances, a rich Muslim capitalist will tend to hire more workers (proletariats) as compared to other groups. Although this may also be considered as discrimination or favoritism, it can also be described as social grouping on social class basis. Another difference evident between the two is that Marx seems to advocate that people are only money oriented thus they base on money. On the other hand, Weber felt that people can either be driven by money or other non-monetary issues when forming social classes. In the modern society, there are those who are capitalists while others are workers. However, people cannot belong in these two extreme groups. There are workers and capitalists who are both honorable. For example, the chief executive officer (a worker) of a particular company and the owner of the same company are two people in two different classes yet of the same status. The above point can also be redefined and explained that one cannot belong to one extreme group as Marx puts it. One can be a worker but also belong to another status due to his/her religion, prestige or even race. It is therefore a challenge categorizing today’s society into three extreme categories. Weber’s social class and status structure may apply to all the societies while Marx’s structure may fail to. For example, in a country like India or China, Marx’s social structure is very evident (20). The capitalists and the worker’s are very evident. However, this changes when the Indians, for example, move in another country. The capitalist-worker structure is no longer applicable but rather the social status comes into being. Regardless of the social class, the Indians come together and support one another when in a foreign country. In the African countries, most Indians are capitalists regardless of what class they were when they were in the home country India. Weber’s social structure describes today’s society more than Marx’s concept. Unlike the earlier days when society was classified on economic terms, today’s society is observant on other key areas in order to make life easier depending on the society.

Ocean Pollution Essay Example

Ocean Pollution Essay Example Ocean Pollution Paper Ocean Pollution Paper You authorized the report on September 23. At your request the formal report presents information on ocean pollution and how it affects the earth. This report presents information in three broad categories: top zone, second zone, third zone. The report includes the six cos of communication and PAP format. As always, helping you with this report and future endeavors is anticipated. So Ocean Pollution Prepared for Prepared by Antonio Burped September 26, 2013 Table of Contents Transmittal Memorandum Title Page 1 Table of contents 2 TOP zone 3 Second Zone 4 Third Zone 5 Conclusion 6 Currently, ocean pollution is a significant issue affecting the oceans and the rest of the earth. Problems like oil spills, toxic wastes, garbage, vehicle pollutants, global warming hazards, and other detrimental materials are all kinds of pollution that damages oceans every day. Ocean pollution directly affects aquatic life and indirectly affects humans and resources. Water shelters 70 percent of the planet making up rivers, lakes, and oceans. Scientists trust the worlds largest garbage dump is found in that water. (The Great Pacific Garbage patch, 2011) There are three zones that make up the ocean: the top zone, second zone, and third zone, all of which are polluted from different things and different reasons. Top Zone The topmost region of the ocean is termed the Epiphytic Zone or sunlight zone. Here you will trace most oceanic life where algae can cultivate lucratively and the temperature is kindlier, which is inviting to most sea creatures. (Surface Area and the Seabed Area, 2010) This zone is roughly 600 et deep, but is the nominal precinct out of the three. One of the numerous kinds of contamination in this zone is oil pollution. This is triggered by ships either leaking, or carrying oil that crash in the sea. Whenever you take your boat out for a good time, it is actually polluting the marine. The boats running engine can kill animals with the chemicals in the exhaust, and the extra gas the engine gives off. Another type of effluence that is most times associated with ocean pollution is garbage dumping, which includes trash, human waste, bathing water, and plastics. Garbage dumping is found in roughly the top 90 feet of the ocean. In that 90 feet you can find six times more pieces of plastic than there is plankton, which is the main food source for many of the sea creatures in the top zone. (Ocean Pollution) (Out of sight, Out of Mine, 2009) Second Zone The second zone is known as the Despotic Zone or twilight zone. Practically no sunlight will ever see this zone, resulting in very few plants being able to grow. The only animals you will find here are those that live with very little sunlight, exceedingly cold water, and extremely high pressure. This zone is ,400 feet making it the second largest zone. Pollution in this zone includes metals and toxic chemicals. These chemicals come from Agriculture causes. Chemical pesticides or fertilizers used to kill harmful insects or substances on land, are the chemicals that are poisoning the fish population. When rain hits plants on land, the pesticides and fertilizers get taken out and run off into the oceans. (Ocean Pollution, 201 1) The chemicals then settle at the bottom of the ocean and eventually are eaten by fish.

College: In contrast to a university, a college traditionally only offers undergraduate degrees and programs. (There are, of course, some exceptions to this definition.) Commencement: Usually another name for graduation. Convocation: On some campuses, each year starts with a convocation ceremony where the new class is officially welcomed and the academic year formally begins. Dean: A Dean is someone traditionally in charge of a major area of a college. For example, there may be a Dean of Students, a Dean of the Faculty, and a Dean of Arts Sciences. Discipline: On a college campus, a discipline is often synonymous with a major. It usually refers to a field of study. (Of course, if you are charged with violating campus or community rules, you may be required to have a disciplinary hearing†¦and t hat definition is more traditional!) Discourse: A conversation, exchange of words, or dialogue, usually incorporating a wide range of views and opinions. Faculty: The faculty, or a faculty member, is generally anyone who teaches at the college. FAFSA: The Free Application for Federal Student Aid. This form is required for any student who wants to be considered for federal aid of any kind. Make sure you get your form in by the deadline! Fees: Fees can be charged for anything from seeing a doctor in the campus health center to returning your library books late. Additionally, you may see something listed as student fees, which cover some student services that the school provides and/or may be the basis for the student government budget. Financial Aid: Anything related to the way you are paying for school. Loans, scholarships, grants, work awards, and any other resource you use are all considered part of your financial aid. Graduate Assistant/Graduate Adviser (GA): A GA is often the same thing as a Graduate Student Instruc tor (GSI). Graduate Instructor (GI): A GI is often the same thing as a Graduate Student Instructor (GSI). Graduate Student Instructor (GSI): A GSI is often a graduate student who helps out in your classes. They made grade papers, lead seminar discussions, and sometimes teach classes. Grants: Similar to scholarships in that you dont need to pay them back. Some grants may be connected to your course of study or allow you to do research while still having your financial needs taken care of. (For example, you may earn a grant to cover your room and board while you do summer research with a professor.) Hall Coordinator (HC): A hall coordinator is typically in charge of your entire hall and oversees Resident Advisers (RAs). Hall Council (HC): A Hall Council is a small governing body that serves as a student voice and helps make decisions and plan programs for your hall community; frequently the same thing as a Residence Council.

IMC Report for Tourism in Gold Coast City in Australia Assignment

IMC Report for Tourism in Gold Coast City in Australia - Assignment Example The intention of this study is the tourism industry as one of the world’s largest and fastest growing industries. The industry is growing fast courtesy of globalization and advanced technology among other factors. The Australian tourism is therefore party of the world’s larger tourism industry that is rapidly growing. The industry contributes a large portion to the Australian economy. For instance, the inbound tourism industry that involves traveling and staying in places outside their usual environment plays a vital role in the Australian economy. The industry contributes to the Australian economy through various ways such as provision of employment and tourism revenues among other ways. Various tourist attractions in Australia are distributed in various states and cities. The Gold Coast City is one of the major cities of Australia that has numerous tourist attractions and hosts many tourists throughout the year. The city is located in Queensland. The population of the city was approximated at 540,000 people in 2010 making the second populous city in State. The city is well known for its tourist attractions such as the sub tropical climate that is characterized by sunny conditions that attract tourists. Other tourist attractions include attractive beaches that are used for surfing, canal and waterway system, nightlife and the rainforest that is close to the hinterland. These tourist attractions are important in attracting tourists from both within Australia and outside Australia to the City. The revenue from tourism is important for the State Economy and the larger Australian GDP. (Tourism Forecasting Committee, 2006). In spite of the revenue collected from tourist attractions found in the Gold Coast City, the attractions are not well exploited in order to reap maximum benefits. This report examines the integrated Marketing Communication strategies that could be used to maximize the benefits from tourism in the Gold Coast City of Australia. The r eport outlines the IMC strategies and marketing strategies that could sell tourism to a new domestic target market, given that it is the highest tourism revenue earner for the city and the country. 2.0 The Australian Tourism Industry The tourism industry in Australia has been growing over time. According to Instinct and Reason (2006), the number of tourists fell by 1% in 2003. However, the number increased in 2004 to 4.77 and in to 5.45 in 2008. The Australian tourism industry grew in 2009

U.S Exam 3 - Essay Example This ruling brought the balance between the state and the federal government. Federalism caused differences in the way the US government operated. According to his judgments, the federal law was more superior to the State. Most of his rulings aimed at reducing the monopolies that overtook the business realm in the 1800’s. Marshal was able to prevent the state government from using too much beyond their jurisdiction to control business activities. In 1810, Marshall made a ruling between Fletcher v Peck insisting that businesses should avoid breach of contracts if they are to succeed. Marshal also ensured that corporation and organization transact business as individuals and own properties like humans. The government played a crucial role in promoting the transport sector during this period. The government built roads, canals, and railways to promote the business industry that was rapidly growing. During this time, sea transport provided the cheapest transport. This encouraged the government to build many canals in the country. Journeys became shorter and business transactions and, operations moved faster. Transport also helped in improving the communication. Most of the letters managed to reach their destinations efficiently. A journey that took 12 hours reduced to 4 hours by the introduction and development of the transport system. The roads and the canals encouraged rural urban migration. Most of the businesses erupted and expanded. The streets were full and, the per capita income of the country rose by 50% mainly due to the new transport resources. Technology was encouraged while mechanization set in. Most of the people changed their demand to manufactured good. Women stopped spinning and bough clothing from the textile companies. The civil war between the South and the North resulted into many farmers abandoning their farms and fleeing their homes. Most of the slaves who were crucial

Different Cultures And Traditions Essay Example for Free

Different Cultures And Traditions Essay Using texts from different cultures and traditions discuss how free will or determinism in form of development or outcome of the stories. (1500 2500 words) I believe that we are not so free in this world even though most people would like to think we are. Our lives are controlled by many factors which we do not seem to notice. Some people accept what their future is and live with it, with out even attempting to change it. Fortunately thought there are also the same amounts of people who can see their own future but strive to do what ever they can to change it for the better. Now through out this essay I will compare two stories which are Veronica and Country Lovers. There are many instances in these stories of how if the main character in the story made a different decision than the outcome of the story would have been completely different. So we will see what might have happened if the character made a different choice later on in this piece but first I will talk about the different points of view brought out in these stories. We shall start of with the story of Veronica. This story is of a girl and a boy who are best friend and they live in quite a poor village in Africa and the boy Okeke gets a chance to go to the city and study at university due to a scholarship which he had won and Okeke asks Veronica to come but she decides to stay. When Okeke, after finishing his course at university as a doctor comes back to the village he sees Veronica in her dying moments. When Okeke asks to save her she refuses because her husband had died and her son had died also so she had nothing else to live for. Now Okeke thinks Veronica should have left with him and become his secretary and should have attended night classes where as Veronica thinks she should stay because she hates to leave her family behind even though her father was a brute and beat her. If we were to compare the points of view established in the story Veronica with the raised in the story of Country Lovers. (This is the story of Thebedi and Paulus.) This story introduces Paulus Eysendyck, a white farmers son, and Thebedi, the black daughter of one of the farm workers. As children, Paulus and Thebedi played together, but when they are teenagers they begin a sexual relationship. They have tender feelings for each other, even though their relationship is ultimately doomed in the end. Thebedi marries Njabulo, a kind young black man who has loved her for years. Two months later, Thebedi gives birth to a light-skinned child.à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½ That Thebedi is pregnant when she marries is not considered scandalous because men in this culture often insist on finding out before marriage if their women are barren. The childs light skin, however, reveals who the father really is. Still, Njabulo treats the baby as if the child were his own. Paulus learns that Thebedi has married and has a light-skinned child. He panics about the child and visits Thebedi in her hut. He asks her to give the baby to someone else to raise, but she does not. Two days later, he asks to see the child alone. Waiting outside the hut, Thebedi hears soft groaning sounds, and the baby soon dies. Officials discover that the baby was poisoned, and Paulus is arrested. Initially, Thebedi says that she knows he poisoned the baby, but when the trial comes, she claims that she does not know what he did in the hut. Paulus is set free. There are clearly two separate points of view which you can clearly see. The point of view of Paulus and Njabulo. Now Paulus is very judgemental and slightly racist. I say this because he wanted to and did kill the baby just because it was light skinned. I can also say this because of the following quote you must give it to someone this proves he is quite racist because he is calling the baby an it who is quite disrespectful. Also there is also a quote which suggests that he could have been the one to kill the baby I feel like killing it myself this also adds some extra evidence against him for killing the baby. And then there is the point of view of Njabulo which is he loves the baby so much he uses the small wages which he gets from his farm work to buy the baby what ever it needs and could ever want. He is such a devoted father. But then again though I suspect that Njabulo might not believe that the baby is not his, I say this because of what he says for Thebedis birthday notice he says Thebedis baby and not their or his birthday which makes me say that he does believe within himself that the baby is his own. I suspect he may think that because the baby has got light coloured skin and because they are both black he would have thought that the baby would have had the same coloured skin as the parent and because the babys skin is light coloured he might suspect that Thebedi might have had an affair with a white man and got pregnant and had a baby. Now we can move on to analyse the language which is used in these texts. Now the language which is used in these two stories are very expressive, they allow us to feel what the character are feelings. I will start to analyse the language used in the story of Veronica. And then I will move to analyse the story of Country Lovers. This in my opinion is a very heart felt and emotional story and I feel it is quite sad that the baby died in the end and that no body was convicted for the death of the baby if there was a murderer. But before we get to that lets start with the language used in Veronica. There are many persuasive words use in this particular text. The language which I have encountered in this text I have never seen or heard of before. Many people have commented on the language which is used in these texts and it is considered to be quite complex but I shall persevere and try to unravel the language in this text for you so that you may understand it as well as I have tried to. There are persuasive words a plenty in this story to help us to understand what the characters in the text are feeling. Now if we move on to analyse the language which is used in Country Lovers. The language which is used in this text is quite complex also so I will try to impart with you the knowledge which I have learnt about the language of this text. Many may say that the words are quite simple but the thing which is hard about the language in this text I the inner meanings within these words which means there is a meaning within a meaning. Now I have scrutinised the language, I will now go on to analyse the structure. There are two main things in the structure which need to be discussed and they are story and characters. I shall start by discussing the story in both of the stories. I have explained at the beginning of this piece the main story lines of these stories but in this paragraph I will go more in to depth about how the author of this story has kept the reader interested and leaving them wanting more. In Veronica for example this story is quite short, even though the story is short does not mean that the story is not interesting or boring. Short stories are just as interesting as novels or long novels. In this story the author has not used many difficult or hard to understand words and all the long / hard words are necessary to give the effect which is given. The author also made it easier for the readers understand what the characters in the story are feeling. For example we said goodbye and she hurtled away. I thought I saw a tear in her eyes as she turned to go. From this quote I can tell that Veronica was really sad about Okeke leaving her and she wanted to avoid a long goodbye because she probably knew the longer she stayed with him the more upset she would get about the thought of him leaving. Now I will move on to analyse the story in Country Lovers. This story is slightly longer than Veronica but is still very interesting. The author of this text does not use many long/ hard words but she does not need to the story is powerful enough and gets the point across without the need to use long and difficult words. This story is quite descriptive, for example: Hidden by the mesh of old, ant eaten trees the more descriptive a story is the better picture of what is happening in the story. If the author is too descriptive it is boring and if there are only few words of description then it isnt very good to get a picture of what is happening in your head. But the author of this story has found the right limit. Now I move on to talk about the characters in these stories. In Veronica there are only two main characters and they are Okeke and Veronica. Now these characters are very well made up and they were designed to play off each other. Where as Veronica is quite resistant to move Okeke is quite happy to try to persuade Veronica to move with him to the big city. Where as in Country Lovers there is Thebedi, Njabulo and also Paulus. Njabulo is quite a shy and retiring type where as Paulus is the alpha male and is more demanding and quite mean and strict. And Thebedi last of all is quite laidback but when she was required of it she was not afraid to stand up for herself. Finally I will analyse if the main characters had main a different choice then what would have happened and how the ending would have been changed. I will start with the story of Veronica. If Veronica had decided to go with Okeke and work as a secretary to him and goes to night classes then she probably would have led a happier and fuller life and also would not have died as early as she did and she would have had a happy and rich family life. In the story of Country Lovers what would have happened if different decisions were made. If Thebedi did not have a sexual relationship with Paulus in her teenage years then he probably would not have come back in her life and Thebedis baby would not have died. Also Njabulo and Thebedis relationship would have been stronger and better. To bring a conclusion to this piece both pieces are brilliant in the way that they are written and put together. They are fantastic short reads which I would recommend to any one to read and also if you wanted to read about different cultures and traditions.

An Introduction to Plastic Gears :: essays papers

An Introduction to Plastic Gears As an employee of a world-class plastic gear manufacturer for many years, I see how this is an undeniably growing part of the gear industry. I hope to briefly describe how something seemingly simple as a plastic gear requires the culmination of many very state-of-the-art processes. Within one word I’ll say that at every level precision is required. Initially, a gear engineer must design a gear that meets the design intent while remaining cognizant of all variables that result from using materials such as plastic. This engineer must design a gear electrode that will actually determine the form of the gear. This electrode is then burned into the mold cavity using a method commonly referred to as EDM or electrical discharge machining. It is essential that the gear electrode be cut identical to the finished gear tooth form. Some compensation is normally made for the shrinkage of plastic as well as the overburn that occurs during the EDM process. The gear engineer normally will alter the gear tooth geometry to relieve stress and strengthen the gear tooth form. This alteration is normally done at the base or root of the gear tooth and at the tip or peak of the tooth. Next, a mold maker then will evaluate what the expected life of the gear program will be so that he can build a mold that is robust and capable producing the many millions of parts with the highest of accuracy. He will ensure that the plastic that will be entering the mold will travel along balanced pathway or runner system that will allow for consistent fill into each mold cavity. His tool for evaluating this flow is done through a computer model commonly referred to as mold flow analysis. He must be capable of understanding what makes a good mold as well as a good gear. Once the mold is completed it is then set into an injection-molding machine. It is important in the precision gear molding industry that the molding unit has a highly controlled system in place to monitor the molding process. It is equally important during this process that there is a means by which all peripheral variables can be controlled. This is done utilizing a central processor, which will maintain balance on all settings for every parameter. Transducers relay all of their information into a central processor that will monitor and maintain this consistent process.

Compare and Contrast the Ways in Which the ‘Natural Environment’ Essay

The natural environment is a key influence in cosmogonic and cosmologic conceptions of human beings as persons among Australian Aboriginal people and to a lesser extent Balinese people. Meyers (1987[1973]) asserts that personhood is socially generated and defined by culture; the conception of personhood in a society is intrinsic to the very nature and structure of human society and social behaviour universally. The environment in which a society is found has particular influence over the social behaviour, structure and interactions of its inhabitants, and impacts on daily life and ritual observances. The Australian Aboriginal understanding of human beings as persons is an amalgamation of cosmogonic and cosmologic concepts of the Dreaming and a â€Å"system of totemism† which govern the ‘social person’ and fluctuate according to variation in natural environment (Peterson, 1972:12). Conversely Balinese understanding of human beings as persons is a â€Å"depersonalizing† system, based on cosmologic concepts of cycles of reincarnation that influence naming orders, status, ceremony and religion, social structure, heavily constructed with a separation of human and animal and a domestication of the natural environment (Forge 1980, Geertz 1973). The differences arising between Australian Aboriginal and Balinese concepts of personhood are derived from variations in ecology, social organization and culture that stem from the distinctive diversity of their respective natural environments and cosmogonic and cosmologic conceptions. Australian Aboriginal understanding of human beings as persons is closely linked to an intimate social and cultural relationship with their natural environment, which stems from cosmogonic and cosmologic concepts of the Dreaming. Bodley (2000:31) explains the Dreaming answers basic existential, meaning of life questions and offers a way of life doctrine prescribing basic social categories and ritual activities, ascribing cultural meaning to the natural environment. The cosmogonic aspects of the Dreaming involve supernatural beings forming the land through their actions and wanderings, leaving trails then re-entering the earth to slumber. (Strehlow, 1978). Australian Aboriginal concepts of personhood stem from the cosmogonic notion that the person is a reincarnation of one of these supernatural ancestors or ancestresses. Strehlow (1978:20) asserts that according to reincarnation beliefs, some part of the ‘life’ left by the ancestor on their trail, could enter into the body of a human mother who crossed these trails, and could take on new life as her human infant. Strehlow exemplifies the Aranda doctrine of conception, and the possession of two souls by every human being, differing from animals in acquiring a second ‘life’ of the ancestor spirit that is immortal (1978:21). Thus Australian Aboriginal notions of personhood are linked inexplicably to the natural environment through place of conception and the identification with an ancestral place of the right patrilineal moiety where the second soul entered and made them a true person. This identification is in the form of a totem, giving the individual certain rights and ritual observances within that natural environment (Peterson 1972:16). Peterson (1972:12) describes the Australian Aboriginal social organisation, and thus concept of personhood, as derived from a â€Å"system of totemism†. The Australian Aboriginal totemic system is based upon cosmologic notions of the Dreaming, and is explicitly linked with conception beliefs. Strehlow asserts that the most important ramifications of conception and reincarnation beliefs of Australian Aboriginals were the totemic relationships that they established and the links they forge between the mortal man and the changeless forces of eternity (1978:24). Totem relations dictate social organisation and kinship, Bodley states that members of a â€Å"band† may be referred to as ‘people of’, whereas individuals may have an affiliation and rights within several countries (2000:37). Conception away from the father’s estate in no way weakens the child’s links and rights in the father’s clan, but rather bestows additional rights and privileges on the estate that he was conceived (Peterson 1972:17). Conception is in terms of â€Å"the water† or spiritual well you come from, a clan estate is the â€Å"bone country†, indicating that the link with the father and patrilineal natural environment has a physical expression in the bones of a person’s body (Peterson 1972:17). Conception and reincarnation beliefs ensure that Central Australian Aboriginal communities were constituted of peoples that belonged o a variety of totems and lands, and that each individual had a personal totem that determined the nature of his rights and duties, and ultimately the understanding of his personhood (Strehlow 1978:26). In contrast to the close identification of Australian Aboriginals with their natural environment, Forge (1980) asserts the Baline se view nature as â€Å"fundamentally fanged and hairy†. This notion is replicated in traditional artwork as consistent representation of animals with prominent teeth arranged in a way that is not found in the natural environment. Forge (1980:6) suggests this arrangement of teeth is part of Balinese culture, highlighting the Balinese aversion to animalism and a desire to emphasize the distinction between animalism and humanity. Furthermore ritual observance of tooth-filing and blackening, of the front six teeth symbolic of undesirable passions, between puberty and marriage is explicitly said to diminish the similarity between man and animal and produce a â€Å"real human† (Forge 1980:239). Forge (1980:7) asserts â€Å"in Bali nature does not produce mankind, even in physical form; the body needs cultural modification to reach true humanity†. Thus the Balinese have an almost tooth-idiom, Forge (1980:12) suggest the Balinese have culturally created a contrast between modified human teeth and the teeth of animal and supernatural beings that symbolize uncontrolled power. Additionally, the Balinese view the forest as an intermediate zone between the world of men, culture and cultivation, and the world of gods, and inhabitants of the forest, good and bad are seen as aspects of humanity with which a person must come to terms with in order to be in control and realize personhood (Forge 1980:15). Consequently the Balinese view their natural environment as power needing to be remade in a cultural and human form through domestication; through control the Balinese human becomes a person. The Balinese understanding of persons as human beings in social organization is derived from a complex system of naming orders that are essentially depersonalizing (Geertz 1973). Geertz (1973:376) states that in Balinese cosmology the stages in human life are not conceived in terms of the process of aging biologically, to which bares little importance culturally, but of social regenesis. Rather than place identifying names or personal names, birth order names and more so teknonyms, e. g. ‘father-of’, are the primary means of identification in Balinese society, furthering Geertz assertion of a depersonalizing social order where enormous value is placed a person’s procreation (1973). Balinese life is not only irregularly punctuated by frequent holidays, but by frequent temple celebrations which involve only those who are birth members of the temple (Geertz 1973:395). Most individuals belong to half a dozen temples or more, thus Balinese life is culturally cross-cutting, dominated by ritual observances and auspicious calendar days (Geertz 1973:396). In terms of the significance of observances of Balinese calendars to the natural environment, the lunar-solar calendar is useful in agricultural contexts so that planting and harvesting are regulated and control of the natural environment is actualized (Geertz 1973:398). Temples have symbolic connection with agriculture and fertility and celebrate the reception of gods according to the calendar (Geertz 1973:398). The Balinese conception of personhood is influenced by shared obligations at a given temple, common residence in hamlets or bandjar and ownership of rice land in an irrigation society (Geertz 1959). â€Å"Bali is a land of temples†, and membership is cross-cutting of these groups in Balinese society (Geertz 1959:994). Temple worship is significant in the concept of personhood and also for ritual observance of fertility and agricultural or natural environment. The irrigation society or subak regulates all matters to do with the cultivation of wet rice, and members are organized according to location to a single water source (Geertz 1959:995). The organization of the Balinese irrigation system within their natural environment provides the context within which Balinese agricultural activities are organized to control and domesticate the natural environment. The natural environment influences Australian Aboriginal and Balinese understandings of personhood in varied ways, as a product of varying cosmogonic and cosmologic beliefs and practices. As Strehlow (1978) asserts, Australian Aboriginal cosmogony and cosmology of their natural environment significantly influences notions of personhood through conception and reincarnation beliefs and ancestral spirits. Similarly Geertz (1973) discusses the impact of reincarnation beliefs on the cosmologic understanding of humans as persons as depersonalizing contemporaries among he Balinese. However, among the Balinese naming orders are transcendent of place, whereas naming of Aboriginal Australians is distinctly tied to place and natural environment in totemic systems. It is apparent that Australian Aboriginal cosmogony and cosmology of the Dreaming and the conception of personhood in society is tied intrinsically to the natural environment. Conversely, the Balinese social organization is largely separate from a preoccupation with the natural environment, and is focused on control and an emphasis on the difference between animalism and humanity. Such divergent reactions to the natural environment are a direct product of variations in ecological surrounds; the totemic identification with the land of the Australian Aboriginals is due to an inherent need to harmonize with the harsh climate. Balinese assertions of domestication and strict boundaries between human and animal are a product of fear of the dangers of the forest. In conclusion, there is no single universal conception of personhood, and the natural environment impacts upon the reactionary organization of a society to either live with or control through domestication, Australian Aboriginal and Balinese respectively. The environment in which a society is found has particular influence over the social behaviour, structure and interactions of its inhabitants, and impacts on daily life and ritual observances, as seen in both the Australian Aboriginal and Balinese people. The different cultural constructions of personhood around the globe cannot be interpreted in terms of narratives of the progressive emergence, either of rationality or of individuality, in terms of European progression, but rather as singular expressions within varying universal social behaviour and organization.

Megger’s Article Response Essay

Betty J. Meggers article, Environmental Limitation on the Development of Culture, examines how environmental habitats directly affect and influence culture. Meggers discusses the differing environmental types and its resulting effect on the people and their cultural development. Her theoretical framework is grounded on the idea that the relationship between culture and its environment is not only based in terms of subsistence (802), but largely to a culture’s experience with diffusion (822). Diffusion can best be defined as a process in which a cultural trait, idea, or behavior is spread from one society to another. While she does believe that the relative strength or weakness of an environment to provide a suitable means for food production affects the adaptation and advancement of a culture, she also believes that cultural diffusion plays a vital role as well. According to Meggers, the general belief is that environmental potentiality is the sole conditioner of cultural development (801). The span of environmental habitats into classified into 4 environmental types, ranging from Type 1 environments, which have the least agricultural potential, to Type 4 environments, which have unlimited agricultural potential. Meggers does generally seem to agree that the environmental type can set limitations on the level of development a culture is able to obtain (816). Because Type 1 environments have the least agricultural potential, tribes must subsist mainly by hunting, fishing, and gathering. Cultures that live in Type 1 environments are relatively small in population size and tend to lead more of a nomadic lifestyle, a necessary part of life because they must continually follow their food source. As a result, their existence is noticeably simplistic because their primary focus is on satisfying only their very basic needs such as shelter and food. This type of environment results in a culture where social organization and technology is very limited in scope. The nomadic lifestyle necessitates that tribes remain relatively small, therefore making the single family the basic social unit. Additionally, technology remains limited to only the most essential tools and utensils due to the limited resources available. According to Meggers, Type 1 and Type 2 environments seem to prohibit cultural advancement because of the limitations imposed on a culture by the environment and the general lack of a suitable source of diffusion. Conversely, Type 4 environments have unlimited agricultural potential because they possess all the ideal conditions necessary for sustaining agriculture. Meggers calls Type 4 environments the â€Å"cradles of civilization† (804) because of their ability to develop and implement the technology necessary to sustain an agriculturally based lifestyle. Type 4 environments are typified by their complex social organization and cultural advancements. Meggers states that Type 4 civilizations are elaborate due to their intensive production of food and the necessary means of distribution. However, Meggers also believes that success of Type 3 and Type 4 environments to advance culturally is also heavily influenced by diffusion across cultures, or a cultures relative exposure and adoption of differing cultural norms, beliefs, and behaviors.

The Killing Of Mudeye Essays - Goldfinger, Free Essays, Term Papers

The Killing Of Mudeye Essays - Goldfinger, Free Essays, Term Papers The Killing Of Mudeye READING JOURNAL This novel is about the killing of a small adolescent troubled boy whom was labelled Mudeye because he was a real victim. I think that Ned is guilty because he has made Linton Begg even weaker because he refused to hand out a friendship to Mudeye. He did this because he was to good to be his friend and he didnt want to be payed out for hanging around with someone so low and not liked. Ned, Mudeye and Goldfinger have many things in common that include the desire to be popular, the lack of happiness, they all are smart, they are all rich, Goldfinger and Mudeye both have strengths such as Mudeye being smart at writing and Goldfinger needing to get a better mark. They are all good at their work and they all have problems with insecurity. I think Ned could have saved Linton Begg because he could have become his friend and helped him to be more secure. He also could have stopped people from hurting him mentally as well. Ned didnt help Linton because had his own insecurities and was too selfish to help. The killing of Mudeye is like a game in life and death where people are rewarded or punished. This is because there is a leader of the game, Goldfinger, and he rewards and punishes people. Goldfinger especially does this to Mudeye. He punishes him to excess. When he stole Mudeyes glasses he punished Mudeye by making him beg. He also rewarded him into their group by making him have a joint and getting him sick. The punishment to Mudeye was a reward to Goldfinger. He loved to see people weaker than him. He gained strength from watching them suffer. The novel is largely about jealousy. It is about Ned being jealous of Goldfinger because he is so good and has the best looking girl in the school and Goldfinger is followed by everyone. There is even jealousy of Mudeye from Goldfinger because Mudeye is such a good writer and Goldfinger gets jealous; he makes Mudeye do his work so he can get a better mark. Goldfinger is also jealous because Mudeye is liked more by one of the teachers then Go ldfinger is and so Goldfinger tries to get back at that teacher. He wants to punish them. When Linton Begg writes, I am only born to suffer he is really speaking the truth because his whole life was about suffering and being picked on and not liked by anyone. His life was a total suffering right up to where he hung himself. He had a problem, though it was Schizophrenia, where he heard voices and was always depressed. He was like this because of his parents as well because they didnt like him and didnt care about him. They didnt want him in their lives. Mudeye is killed by his mental disorder but also his insecurity. He really did get the mental disorder because he was so insecure and nobody wanted to know him not even his mother and father. He was alone and marginalised continually by everyone. The Killing of Mudeye is about reconciliation with the past and Ned does achieve it very well because he is really disturbed when he relives his whole school life. He decides to face where the killing of Mudeye is done and it makes him feel a lot better.

It should be remembered that purpose of this paper is purely academic and most of the research done is secondary in nature. The market can be defined as an institution or mechanism that brings together buyers and sellers of a particular goods, services or resources in order to determine a price and set equilibrium at the point where the plans of buyer meet the plans of the sellers. From the above point, it is very clear that market equilibrium occurs at price or a point where the buyers are willing to buy a particular quantity of goods at a going market price and similarly sellers are willing to sell the same quantity of the goods at the same price. In simple words, market equilibrium is related to demand and supply. In order to understand the equilibrium situation in detail, let’s first look at the meaning of the terms, demand and supply.

Setting up a business in China Essay Example | Topics and Well Written Essays - 2500 words

Setting up a business in China - Essay Example This research will begin with the Chinese business culture. Chinese people perform a different form of business and culture as compared to the rest of the world especially the West. However, with the uniqueness of the Chinese history and background, China always has a special culture of business and etiquette. A simple business culture can mess a working relationship that was doing well. Conflict of culture between Chinese and another culture may cut short a working business relationship. Chinese businesses are usually based on being referred by another business associate; could be in the same business or in another business field. However, a strong recommendation from such an associate is required to win favour of clients and get good deals.Chinese business starts on a social plate and continues along the same line unless something happens that may break relationship between parties involved leading to business termination. Unlike Western culture where business is profession based, Chinese business is more of a social affair than a professional one. This is essential to help attract more clients and win hearts of many people in business. It helps maintain one’s clients in business socially rather than professionally and this increases business returns. The more one goes social in business in China, the higher the returns. Getting personal in business and sharing one’s personal life acts as an incentive to business partners. Business partners usually take this as getting close to them and this may be their interest even before they do their business with the party involved. It is therefore imperative to get personal and avoid too much of being professional as this will guarantee high returns within a short period of business. Spending time in sharing personal life in business attracts business associates from China. Personal life may include political views, hobbies, and family life among others. Protocol and priority are vital in business in Chin a. Protocol and priority comes in when dealing with people of different ranks. Recognition is of essence to show these individuals that one recognizes their rank. Address people with their correct designation, for example, Director, Doctor, Professor, and Chairman. This will make the parties see that their rank in whatever field they are in is highly recognized even in business. Giving business cards during business meetings indicates that one is serious in doing business. A business card should face the recipient. Such a card should have one side translated to make it easy for the Chinese party to understand what one is selling to them or buying from them. It is important to mention one’s company and the rank one holds before business gets underway. Business in China pays much attention to respect. Parties are supposed to display respect to each other according to rank. It may not be easy to excel in business in China without understanding that respect is tantamount to busin ess success. It is necessary to establish contact with a client one is dealing with so as to get as much referrals as possible from that client as business progresses. One should act as an interpreter to himself to make it easy to identify with Chinese as they like business where they understand what they are dealing in. It is vital to explain legal aspects of the business one is handling to be sure of the legal implications when doing any kind of

BHP Billiton Case Study Example | Topics and Well Written Essays - 3500 words

BHP Billiton - Case Study Example Apart from some specific small scale mining especially in high value low volume minerals, extraction of mineral resources usually requires large scale, capital intensive investments, Most projects are technologically challenging and investments are characterized by high degree of uncertainty and long gestation periods. In most developing countries except China and India, extraction industry seems to be export focused with significant scope of revenue creation but limited scope of employment generation. Mineral extraction also involves considerable threat to an ecosystem, and could have adverse social implications. Finally, mineral resources are non-renewable and often of strategic, geo-political importance. As a result, governmental influence tends to be high, which can interfere with the business operations. Owing to the huge capital investments required for extraction, this market has seen emergence of state-owned enterprises, which can depend on the government for the huge capital investments that they incur. Not all developing and least developed countries can afford the high capital investment. Therefore, this market is also characterized by the presence of large multi national corporations (MNCs), which have the financial power to make huge financial commitments. Exploration activities for minerals can not only take up long gestation periods, but can als... Exploration activities for minerals can not only take up long gestation periods, but can also result in unsuccessful attempts. Even after successful exploration, the investor needs to face the technical risk (involved in extraction at sometimes difficult sites), and market risk (demand and supply risks), political risks (nationalization). Political risks can be higher if the host country has a weal constitutional framework. This is a risky business and the investor should have the expertise necessary to handle such risks. Once investment is committed, the cost of pullout is very high (United Nations Conference on Trade and Development, 2007). Section-III About BHP Billiton The largest extractive company, BHP Billiton was chosen as the subject of this case study. Its mission, marketing strategies are explored in the subsequent sections. The mission statement of BHP Billiton is "to create long-term value through the discovery, development and conversion of natural resources, and the provision of innovative customer and market-focused solutions". BHP Billiton is a global resources company in the extractive sector headquartered in Australia. It is a dual listed company and consists of BHP Billiton Limited Group in Australia, and BHP Billiton Plc group in the UK. IN addition, American Depository Receipts (ADRs) of both companies are listed Ney York Stock Exchange (NYSE). It was created in 2001 by the merger of Australia's Broken Hill Proprietary Company (BHP) and the UK's Billiton, which had a Dutch and South African background (Wikipedia, 2009). It is the world's largest diversified natural resources company, and has significant businesses in alumina and aluminum, copper, energy (thermal) coal, iron ore, nickel, manganese,

Security And Confidentiality On The Internet Information Technology Essay

Security And Confidentiality On The Internet Information Technology Essay On 9th of November 2009 The Internet teacher requested 3000 word report related to the FETAC Internet module. This report was to be submitted by 14th of January2010. The topic of the report is Security and Confidentiality on the Internet with reference to cookies, viruses, encryption, digital signatures, firewalls, filtering software and personal privacy. Recommendations were requested. 2. Method of Procedure I found most of the information on the internet. In order to obtain the relevant information, I used Google Search Engine with keywords in English: Internet Security, Privacy on the Internet, Malware, Computer Viruses, Cookies, Firewalls, Filtering Software, Encryption, Digital Signatures, Computer Protection, Threats on the Internet. Keywords in Lithuanian: Privatumas Internete, Saugumas Intenete, Kompiuteriniai Virusai, UgniasienÄ-s, Filtravimo PrgraminÄ- Ä ®ranga, Ã…Â  ifravimas, Skaitmeninis ParaÃ…Â ¡as, Pavojai Internete. Also, some printed sources of information such as books and a periodical press in English and Lithaunian were adopted. Several pages for each topic were checked to confirm that the information was correct and fully understud. That hepled me to make conclusions and to give recommendations. 3. Findings 3.1 Importance of Subject With the progress of affordable technology more of us store more and more of our life in bits and bytes. By the end of 2009 there was more than 1,5 billion Internet users in 260 countries on every continent. The Internet is not a single network, but a vast array of connected networks situated all over the world, easily accessible by personal computers, notebooks, netbooks, smartphones, PDAs, game consoles, advanced TVs, same photo cameras or even kitchen appliances as hi-tech fridges and microwaves in a variety of ways. Today, the Internet uses gateways, routers, broadband connections, Wi-Fi spots and Internet service providers (ISPs) to make itself available at all times. Individuals and organizations worldwide can reach almost any point on the network without regard to national or geographic boundaries or time of day, there is some exceptions regarding to Internet censorship. Nowadays, it become hard to find the business without any connection to the Internet, because of its excellent source of marketing, convenience, high speed, low cost, and almost unlimited possibilities. Institutions of education, hospitals, banks, institutions of public service, providers of mobile service and internet, utility companies and of course our government has our personal information on their computers and they are connected to the Internet. With the birth of Social Networking Sites such as Bebo, Facebook, MySace, Twitter ect., we sharing our pictures, personal details, our thoughts and lives with friends and if we are not careful with everybody on the Internet. Just Facebook on its own has more than 400 million users. Even more, with new generation of Internet- Cloud Computing, individuals and business users are storing less data on their hard drives and more in the cloud- remote servers, operated by giants like Google and Amazon. However, while using the Internet, along with the convenience and speed of access to information come new risks. Among them are the risks that valuable information will be lost, stolen, corrupted, or misused and that the computer systems will be corrupted. If information is recorded electronically and is available on networked computers, it is more vulnerable than if the same information is printed on paper and locked in a file cabinet. Intruders do not need to enter an office or home, and may not even be in the same country. They can steal or tamper with information without touching a piece of paper or a photocopier. They can create new electronic files, run their own programs, and even hide all evidence of their unauthorized activity. So if we are closing and locking the door in our house to prevent criminals gain access to our valuables, we must take care of our house and life in the digital world and use all possible security and privacy on the Internet measures against the threats. WORLD INTERNET USAGE AND POPULATION STATISTICS World Regions Population ( 2009 Est.)

Most security breaches are not done by technology, but by social engineering. In security, people is the most risky factor of all, yet its the one thing thats often forgotten. A company may setup firewalls, security software, locks and fingerprint scanners, but if they forget to establish and enforce a well designed security policy, they have forgotten the most important part. The easiest way to get a password from someone is just to ask! In more likely situations, an attacker may simply call random people and pretend they are a tech support person trying to fix a problem, and ask for confidential information as part of the diagnostic. Pretexting Pretexting is the way of stealing information by providing just a little bit of known information, and pretending to be someone youre not. Thats how identity thieves can call banks and, after a few tries, by simply providing basic information about the target, get all the data they want. Phishing Phishing is when you receive an email that looks like its from your bank, Paypal, online shop or another secure site you use, and asking you to login to confirm your information. It works in this way: the criminals sets up a website which looks like the genuine one and then sends phishing email to thousands of people, until they find somebody. Then when the person tries to login, his login information is intercepted by the bad guys and used to steal valuable information. Malware Malicious programs, especially Key loggers can record what keys on the keyboard you are pressing when login to secure websites, to obtain your username and password. Often Key loggers are incorporated together with Trojan Viruses, programs which pretends to be useful software i.e. antivirus or computer maintenance programs, to send stolen information to the criminals. Privacy threats on Social Networking Sites Internet users have to be very careful with the private information that they share on the web. Internet is becoming very popular way to communicate with people. Most people who give too much of private information about themselves arent aware about the risks they taking. There are people who can pretend to be your friends, gain information and use this information against you for blackmailing, psychological terror or for access to secure private pages. Conclusions and Recommendations The offenders are always inventing new methods to steal private information. We have to be aware about that, constantly refresh our knowledge about security and existing scam schemes and take all possible security measures by using trusted up to date security software. Never click a link in an email from unknown sender, never download from an untrusted source, and always type in the address of your financial sites to access them. Need to avoid to disclose sensitive information online especially to the people we dont know very well. Also we have to remember that these attacks also can be done offline. Most identity thefts are done by people simply going through rubbish bins and getting confidential data that was thrown out, like a bank statements, invoices, payslips ect. We cant do much to secure our personal data collected and stored by businesses and institutions which can also be stolen or misused, just hope that they will take same good care as we do. 3.3 Cookies What are Cookies? Cookies are a piece of text that a web server sends to web browser and are stored on a users hard disk. Main purpose of cookies is to help prepare customized web pages with our settings, interests, browsing habits. It works in similar way to loyalty cards i.e. if we bought a book in Amazon internet shop, next time when we come back to Amazon first it will offer similar books to our purchase. Cookies do not act maliciously on computer systems. They are text files that can be deleted at any time. Cookies cant be used to spread viruses. But because any personal information that we gave to a web site will be stored in a cookie some people can accept it as a threat to privacy and anonymity. To prevent misuse of information in the cookie if its stolen, information in the cookie is encrypted. How do They Work? When we visit a site that uses cookies, it can ask the browser to place one or more cookies on the visitors hard drive. It will contain our name and password, fill in form i.e. delivery addresses and basically what we do in the page. Next time, when we come back to the site the web browser sends back the cookies that belong to the site and then we will see personalized Web page with our details. Generally cookies help us to save a little bit of time. And we always have possibility to switch it off, however internet shopping web pages requires cookies to accesses them. How Could I Prevent/Manage Cookies? If we want to delete cookies we have to follow these steps: Internet Explorer: Tools /Internet options/Security /Set security level to high or custom level/Cookies/Disable. Mozilla Firefox: Tools/Options/Privacy/Cookies/Uncheck/Allow sites to set cookies Other options are to use designated Cookie Managing software or to use advanced Antivirus programs which also have the option to control cookies, to block cookies that we dont want and save only the cookies that we want. Conclusions and Recommendations I think that cookies are useful because we can get personalized information to read, do not spend time on security questions where it is necessary to enter a password, we dont have to spend time filling up same forms. Cookies do not collect information saved in the computer, it can contain only private data that we give to a website on our own free will. And if we dont want some cookies we are able to remove them from computer when we want. Some websites such as internet banking, e-shops and similar are impossible to use properly without allowing the cookies. 3.4 Viruses What is a Virus? Computer viruses are small malicious program codes, which are designed by using various techniques to hide themselves inside the executable files. Their aim is to replicate, spread between the computers using removable media or network and to interfere with computer operation: slowing down computer, damaging or deleting data, disturbing users and wasting time by showing annoying massages. Virus can be classified by several characteristic: depend on the origin, on the way how they infect computer, on the place where they hide, on the damage that they can cause However, the computer virus is only one type of the malicious software or malware, but majority of computer users referring to all malicious programs (Trojan horses, worms, rootkits, spyware etc.) as the viruses. Type of Virus Different viruses can have many common characteristics and constantly appearing viruses with new specifications or combinations. Resident Virus. Loads the replication module into RAM memory when is executed, after this virus can infect all files that are accessed by user or operating system. If the antivirus program fails to spot the virus in the RAM it can infect all scanned files. FAT Virus. The File Allocation Table is a fundamental element in the system it works like an index, keeping information where is the files stores on the hard disk drive (HDD), which sectors are empty etc. If this vital index is destroyed by virus, it makes impossible for computer to locate files. It also can overwrite the files or entire directories corrupting them permanently. Sometimes the only solution to fix the computer affected by FAT virus is to format hard disk drive. Huge downside of this is that all information on HDD will be permanently erased. Virus of Direct-Action. Sometimes referred as Non-Resident Virus, they are unlike to resident virus, not loading in to RAM memory. They try to infect the programs and cause damage at the moment of execution of infected file. Most of viruses are Resident. Overwriting Virus. Most destructible type of virus, it overwrites the information in the infected files corrupting them permanently. If you dont have the back-up copy of your files its a bad news because the only way to get rid of this type of virus is to delete infected files. Boot Virus. Also known as System Virus. These viruses infect critical section with boot code on hard disk or another bootable media storage that helps to start computer. When the computer starts up and the boot virus is launched, it can take complete control over infected computer and does everything it wants (steal private information, delete system files etc.) Clean bootable antivirus software required to disinfect the system. However depend on the virus this solution is not enough to clean bootable sector. Macro Virus. Macros are micro-programs associated with a file that serve to automate joint complexes of operation. Macro virus expand from applications which use macro, word document (file with extension .doc),Excel (file with extension .xls) data of Access (file with extension .mdb), Power point (file with extension .pps). When we open a file containing a virus of this type of macros are automatically loaded causing the infection. Most applications that use macros have, but many macro viruses easily circumvent this protection. Multipartite Virus.Very advanced type of virus that can perform multiple infections combining different techniques. These viruses are considered very dangerous, for its ability to combine many techniques of infection and harmful effects of their actions. File Virus. Infect programs or executable files (files with extension .ex and .com) when run the infected program, the virus becomes active, producing different effects. The majority of exiting viruses are of this type. Logic Bombs.Neither virus is considered strictly as they do not reproduce. They are not separate programs, but hides in an unmarked segment within another program.They aim to destroy the data on a computer or cause other significant damage on it when certain conditions are met. While this does not happen, no one notices the presence of the logic bomb. Its action can be extremely destructive. Trojan Virus.Trojan arent considered virus, because they dont replicate themselves. Trojans are commonly hidden in the programs that appliers to be useful, but instead opens unauthorized access to users computer. Trojans also can be installed thorough web pages with executable content (ActiveX control), email attachements. The effects of the Trojan can be very dangerous, allowing remote control from other computer (downloading, uploading, modifying or deleting files), installing key loggers and other malware, connecting computer to botnet (sending SPAM messages, perform network DDos attacks). How can computers become infected and what damage can cause? Viruses can infect computers through: Internet (email attachments, infected web pages, downloading infected files) Computer networks Removable Media Drives Virus Symptoms: The computer runs very slow Reduces the available memory The computer shuts down or freeze frequently There are programs which do not work or malfunction There is less free space on your hard disk Computer files disappear Strange messages appear on the screen. Some file are renamed or extended Conclusions and Recommendations Not everything that affects the normal functioning of a computer is a virus. Is very important to have means to detect and disinfect viruses use an antivirus program and update daily (use default settings). Scan all removable disks before use it and scan computer periodically at least once a week. 3.5 Firewall A firewall is a system that protects a computer or computer networks blocking unauthorized network access while permitting authorized communications. Firewall can be implemented in software, hardware or combination of both. Firewall is placed between protected and unprotected networks and acts as a gate to protect network or single computer, by inspecting network traffic, applying rules and allowing or denying connection. Firewall can use different techniques to do so: Packet filter (inspects every information packet passing through the network) Application gateway (applies rules to specific applications such as FTP, Telnet servers.) Circuit-level gateway(applies rules to TCP or UDP connections, when are made there is no further inspection.) Proxy Server (checks all network activity passing through network.) Conclusions and Recommendations Everyone should use a firewall against network intruders to protect computer and private information. Most of the antivirus programs and operating systems have integrated firewall software. Minor disadvantage of firewall, it can slow down Internet traffic and can be tricky for not advanced users to set-up it properly (not blocking traffic for useful programs). 3.6 Filtering Software The filtering software is designed to control what contents are allowed to be accessed on Internet. Often its installed on the computers of educational, government organizations, private companies. Filtering software is commonly used by parents to prevent their children from having access to certain web places unsuitable for minors. It also can be used as the mean of censorship in some countries. How does it work? Nowadays on the market there are many options of filtering software with various techniques and content filtering to prevent from harmful online material. The filtering programs works like that: Address blocking websites containing such content Controlling access times Accepting default address list Possible to establish your own list of addresses Assigning different profiles or different days and times(work, leisure, etc.) Controlling which services can be used at any time and for each user (mail, chat, etc.) Advantages and disadvantages of Filtering Software. Advantage of filtering software is that does not allow minor to access pages of violence, pornography, racism. In a work place it prevents employees of wasting their time and resources for personal proposes (chatting online, social network pages, etc.). Main disadvantage is over-zealous filtering. Par example, in some filters attempts to block the word sex would block words such as Essex and Sussex and etc. Internet censorship in some countries limits freedom of speech for different reasons and that is not a good thing. Some Filtering Software examples. Netnanny, Mobicop, DansGuard, CleanFeed,Web Sence 3.7 Encryption Its a method to convert the characters of a text that can not be understood unless it is read with the corresponding key. Used to protect the integrity of secret information if it is intercepted. Encryption is also used when data is sent via secure intranet (VSPN). Encryption is used for electronic commerce to protect credit card information. How does it work? The keys are the heart of the encryption. The keys are complex mathematical formulas (algorithms) used to encrypt and decrypt information. If someone encrypts a message, only one with the appropriate key can decrypt the message. Algorithms are used to perform a hash function. This process produces a unique MD5 for this message. The MD5 is encrypted with the senders private key resulting in a fingerprint. Conclusions and Recommendations Everyone who has and important or secret information (banks, hospitals, government, universities, e-commerce sites) they have to keep this information in secret from fraudsters. In recent years, it was few cases when portable computers of government organizations with secret information were lost or stolen. Laptops (portable computers) became more and more popular and most of us have some kind of personal information on our computers. So it is very important to have that information encrypted, in case of losing it. 3.8 Digital Signatures A set of data in electronic form attached to or associated with others which are used to identify the signatory, which allows you to check the provenance, authenticity and integrity of messages exchanged over the Internet. There are two types of electronic signatures: basic and advanced. The basic does not guarantee the identity of the signer, neither the veracity of information received since the sending does not ensure that the issuer has made it known to us, while the advanced signature identifies the signer and detect any subsequent change of data that could occur. The digital signature is a specific techology signature and created by the so-called System Asymmetric key cryptography and it works like that : The holder has two keys : public key and private key ,private key is only known to the issuer and is associated to the information you send .while the person who received only know their public key . Two keys are needed and complement each other to get the encrypted message appears as the original . When we want sent private information the information is encrypted by system which use mathematical operations so the information becames encripted ( strange numbers and letters) so the message only can be deciphered by the people who know the instruction and have a public key Conclusions and Recommendations It should be used by the organitations which have an important or secret information as banks, universities, hospitals, etc., these organitations should use digital signatures in order to avoid the risk of fraud .they have to be sure about the authenticy of the sender.
