Comparison between Dead Man's Path and A Tale for Children Research Paper

Comparison between Dead Man's Path and A Tale for Children - Research Paper Example Obi has an intention of closing the path that leads to the burial grounds of the village; however, the villagers contest this action because it puts their heritage, as well as culture into compromise. A person's approach, along with his character in compelling modernization over traditional beliefs is capable of giving rise to conflicts, while, at the same time, resulting into consequences. In Dead Men's Path, the author uses symbols in the setting, as well as characterization in expressing the theme (Achebe 10). In Dead Man’s Path, Obi closes the path to the road that is capable of taking away an opportunity, something that makes this story is a tragedy with a number of symbols. Living in a world that is full of hatred is uneasy, however, living in a world full of happiness happens to be the entire package. In Dead Man’s Path, Obi the chief director of the school makes a wise decision of closing this road since the majority of people in this area go there. Immediately after closing this path, residents begin to get angry; Obi is terrified by the unfolding of these events, especially when people begin coming up to the school, while, at the same time, tearing down everything, not sparing even the school (Elizabeth, Susan & Robert 25). There are a number of horrific things happening within this short story thereby making it a tragedy; being in possession of a school whose path leads to the dead turns out to be an idea that is that amusing. Initially, there is a rise to power when Obi obtains the promotion, which results in him erecting the fence around the school. These actions infuriate the people living in the town; the following day, a pregnant woman, goes into labor, but dies while giving birth, something that infuriates the villagers even more since they think that it is as a result of the closing of that path. It is possible that the baby’s spirit was to exit from where the fence was hence the death of both the mother and baby. After th e woman’s death, people assume that if the path was still open, both the woman, as well as the child, would still be alive and safe. When night falls, they take distinctive items and go ahead to tear down the fence, together with the school. These actions lead Obi to think twice concerning this situation; however, he still does not understand what he did wrong that led to the tragic fall of the fraying down of the fence. In this case, there is a perception of death or death symbolism as following the death of the woman, as well as her baby (Achebe 35). Dead Man’s Path turns out to be a tragedy comprising of a number of symbols. Living for the duration of that time was probably the hardest thing; however, the people of the town succeed in getting through these hard times. Obi fails in understanding that every person in life is in need of a path to walk on, as well as a place to set off in the future. Although Obi’s intention was to help the people in the village, in reality he did remarkably little in helping them, thereby ended up hurting them even much more (Elizabeth, Susan & Robert 68). A Tale for Children is quite different compared to Dead Man’s Path; considering that it is distinctive of a style referred to as magic realism, which is closely incorporated with its author, the Gabriel Garcia Marquez, who is a Colombian novelist. This imaginative style brings together realistic, daily details with

Reason for Returning to School Essay Example for Free

Reason for Returning to School Essay The reason of why I decided to go back to school and obtain my Bachelor Degree has never been anything out of the ordinary. In todays society, I see many working adults pursuing their degrees to obtain security and self-fulfillment. While others are looking for the advancement in pay and position in their current or new job. There are even those who need to gain more confidence in their skills to do a good job for their company and they feel that by getting a degree, they can achieve this goal. All of them pertain to me. Especially to todays current economy, I strongly feel that there is a great advantage to having a degree versus to not having one when it comes to searching for a job. More and more each year, I see new programs for education that are designed for working adults. If there were no real demand for these programs, I believe they would not exist. But that demand is real. There is a larger competitive environment in the work force now then there was a few years ago. With many new and fresh graduates coming out of college, I feel the pressure to increase my credentials to be able to compete. Even though I have built my experience through years of on the job education, I feel that by obtaining a graduate or even undergraduate degree is the only way to secure my position against the growing population of new graduates. I believe that you must continue updating your skills to keep up with this very competitive market. Then, there are those current working adults who are already established in their field, but would like to find a way to increase their potential of getting a raise or promotion. By obtaining a degree, this can show the managers how much value of an employee you are to the company. To have the qualifications and experience can give you a better success rate of getting the raise or promotion that you would ask for. Its a way of selling yourself and your worth. With a degree, you just are more armed to the task of requesting for an advancement. Once I have obtained my degree, I can then see myself seriously requesting for an advance of my pay and position from my manager. Most importantly is the ability to feel confident in doing your job and to  have that credential to show people. There were many projects that I have been involved in that required myself to learn new skills. One example was learning how to program in Visual Basic 6 to create an interface GUI for one of our robot systems. Another accomplishment that I achieved was generating a database for system files used by our integration department. In almost each project, there were other managers involved besides my own manager. And each one had their doubts in my ability to succeed in the project. I have yet to fail, but each time a new project is started, these doubts from these managers come along with them. Even though I have five-years of experience in my field, I can see that it is harder to prove your ability in your skills with out a four-year degree. It is also much harder to have the confidence in yourself when there are others that lack that confidence in you. That is why I can se e by obtaining a degree can benefit me in many ways besides security and advancement in pay and position. There are times that I try to imagine how different it would be one I have earned my degree. And each time all I can imagine are anything but positive results. Sure, there are concerns and sacrifices that I would need to make down the road. Sacrifice like time. Time with my family and time for myself. But what is a couple of years of sacrifice compared to a lifetime of advancement? I once read an article about a successful businessman and how he achieved his goals by following one philosophy he recited to himself everyday. He believed the reward in terms of happiness is directly proportional to the sacrifice that each one makes. Great philosophy. And I try to live it everyday.

Now they expand their business all over the world and for that TESCO need to care full about there marketing because different country has different type of customer and their needs also no same. 23 Introduction TESCO is top leading retailer in UK. It manages over a thousand supermarkets, hypermarkets, and convenience store in the United Kingdom, Ireland, central Europe, and Asia. TESCO started life in 1919 when Jack Cohen started surplus groceries from a stall in the East end of London. MR Cohen made profit of 1 from sales of 4 on his first day. TESCO brand first appear five years after in 1942 when he bought shipment of tea from a MR T. E Stockwell. From that time TESCO slowly improve in retail business and now they are take top position in UK retail business. Tesco aim is provide best products for their customer and make sure about customer requirements. Definitions of Marketing The definitions of marketing of marketing can be divided into two categories: Classical (narrow) and Modern (board) The classical definition of marketing has several weaknesses that are overcome in the modern definition. A proper definition of marketing should not be confined to goods and service. It should cover organization (for example, Florida Orange growers), people (political candidates and celebrities), place (Denver, Colorado), and ideas (the value of a college education). Figure 1-1 definition of marketing:- Classical / narrow Modern / board 1. Marketing is the performance activates that direct the flow goods and service from producer to consumer or user. (Ralph S.Alexander (Chairman), Report of the definitions committee, journal of marketing, vol. 12 (October 1948), pp. 202-217) 1. Marketing is the exchange taking place between consuming groups on the one hand and supplying groups on the other. (Wroe Alderson, marketing Behavior and Executive Action (Hoewood, 3 Richard D. Irwin, 1957), p. 42). 2. Marketing is the process in a society by which the demand structure for economic goods and service is anticipated or enlarged and satisfied through the conception, promotion, and physical distribution of such goods and services. (Statement of the Philosophy of the marketing faculty, the Ohio state University, The journal of marketing, vol. 29 (January 1965), pp. 43-44). 2. Marketing is concerned with regulating the level, timing, and character of demand for one or more products of an organization. (Philip kotler, The major task of marketing Management, Journal of Marketing, vol. 37 (October 1973), p. 42). 3. Marketing is human activity directed at satisfying needs and through exchange processes. (Philip kotler, Marketing Management: Planning, Analysis, and Control, fourth edition (Englewood Cliffs, N.J.: Prentice-hall, 1980), p. 19). Main Characteristics of Marketing There are four main characteristics of marketing oriented organization: Production Orientation: This is organizational or values where competitive advantage is attained through increase productivity or volume. Its a traditional orientation that exists in the Henry ford era. In modern times this is practiced in compliment with other orientations. Product Orientation: An organizational culture where competitive advantage gained through the creation of product leadership (high quality features) becomes the sole objective of a business. Sales orientations: An organizational culture where competitive advantage attainted through the creation of superior sales force to generate adequate sales becomes the objectives of a business. Carphone warehouse attained its objectives through telemarketing. Marketing Orientations: An organizational culture where beating competition through the creation of superior customer value is the paramount objective throughout the business (piercy, market led strategic change 2001). Key elements of market orientation The main key elements of market orientation are: Customer orientation: Understanding customer well enough to create superior value for them. Long term profit focus: Having this as strategic focus business objective. Interfunctional coordination: Mobilising all company resource to create value for target customer. Competitor orientation: Awareness of the short and long term capabilities of competitors. Organizational Culture: Management and employee behavior to focus on customer satisfactions a value. These are the key aliments that must be flow in oriented organization. Benefits of marketing approach High customer satisfaction, loyalty and retention Increase sales and market share Growth in profitability Enhanced competitive advantage Improved corporate image Cost of marketing approach Increasing customer expectations Staff training and development needs Technology requirement for customer contact and improved ways of doing business Increase resource demand to providing customer specific marketing Complex customer growing needs and power Market orientation assessment Customer orientation Regular collection of information on customer needs Customer focus corporate policies and objectives Regular customer satisfaction review and improved service levels Responsiveness to customer needs Market offers reflecting the various needs of distinct segments Competitor orientation Regular collection of information on competitor activities Responsiveness to competitor actions Bench marking on competitor offering Differentiating on the basis of customer needs Market segmentation criteria In addition to having different needs, for segments to be practical they should be evaluated against the following criteria: Identifiable: the differentiating attributes of the segments must be measurable so that they can be identified Accessible: the segments must be reachable through communication and distribution channels. Substantial: the segments should be sufficiently large to justify the resource required to target them. Unique needs: to justify separate offerings, the segments must respond differently to the different marketing mixes. Durable: the segments should be relatively stable to minimize the cost of frequent changes. A good market segmentation will result in segment that are internally homogenous and externally heterogeneous, that is, as similar as possible within the segment, and as different as possible between segments. Base for Segmentation in consumer markets: Consumer markets can be segmented on the following customer characteristics: Geographic Demographic Psychographic Behavioralistic http://www.netmba.com/marketing/market/segmentation/ (access-05-01-2010) Targeting Strategy There are several different target-market strategies that may be followed. Targeting strategies usually can be categorized as one of the following: Single-segment: strategy also known as a concentrated strategy. One market segment (not the entire market) is served with one marketing mix. A single-segment approach often is the strategy of choice for smaller companies with limited resources. Selective specialization: this is a multiple-segment strategy, also known as a differentiated strategy. Different marketing mixes are offered to different segments. Product specialization: the firm specializes in serving a particular product and tailors it to different market segments. Market specialization: the firm specializes in serving a particular market segment and offers that segment an array of different products. Full market coverage: the firm attempts to serve the entire market. This coverage can be achieved by means of either a mass market strategy in which a single undifferentiated marketing mix is offered to the entire market, or by a differentiated strategy in which a separate marketing mix is offered to each segment. The following diagrams show examples of the five market selection patterns given three market segments S1, S2, and S3, and three products P1, P2, and P3. Single Segment Selective Specialization Product Specialization Market Specialization Full Market Coverage S1 S2 S3 P1 P2 P3 S1 S2 S3 P1 P2 P3 S1 S2 S3 P1 P2 P3 S1 S2 S3 P1 P2 P3 S1 S2 S3 P1 P2 P3 http://www.netmba.com/marketing/market/segmentation/ (access-05-01-2010) A firm that is seeking to enter a market and grow should first target the most attractive segment that matches its capabilities. Affects of buyer behavior One of the most important parts of marketing is buyer or customer behavior. Because of that TESCO must understand why a customer or buyer makes a purchase. Without such an understanding it is hard for TESCO to respond customers needs and wants. According to Peter Clark, co-editor of the Wise Market and co-author of the loyalty Guide reports series, there are six major factors that play key roles in influencing the loyalty and commitment of customer: http://www.thewisemarketer.com/news/read.asp?lc=w29860tx2320zs (access-05-01-2010) This six factors working when every customer goes to buy something. There for TESCO contain to this factor. Because of customer different needs TESCO has focus to maintain what they want and it also depend on different buying situation. There are two main factors that influence a purchase: Cultural factor: Cultural factors have a significant impact on customer behavior. Culture is the most basic cause of persons wants and behavior. Growing up, children learn basic values, perception, and wants from the family and other important groups. Social factor: A customer buying behavior is also influenced by social factors, such as the groups to which the customer belongs and social status. http://www.tutor2u.net/business/marketing/buying_introduction.asp (access-5-01-2010) This all factor effects on TESCO marketing operation because customer is now king and every business have to make sure about there needs. For example in local market means UK TESCO can sale pork but in Asian market it is not possible to sale pork in every place. Organization duty to make sure about customer requirements and also maintain there cultural and social wants. Marketing Mix The concept of a marketing mix is best described by (1990, 43) claiming that is the set of controllable marketing variables that the firm blends to produce the response it wants in the target market it is compose of 4ps: product, price, place, and promotion. In the context of TESCO, their entry to the Chiness market should significantly adapt to the culture of the consumer in the said location. However, the company should take into keep in mind the basic standards to which their company adheres to. Product: The management of TESCO should set off product development strategies once they have taken control of their shop in China by marketing their existing products, exporting products in different province of the country and in so doing pressing forward on the possible opportunities of boosting the companys market penetration and market share. Tesco should consider restoring or revising models of their product to provide the Chiness customers what they want and what they need. In this way Tesco could develop the stores own brand product which could be marketed strategically within the territory of china. Price: Looking at the situation of Tesco, one way that it could acquire cost advantage is by enhancing process efficiency, expanding exclusive contact to a large supplier of lower cost materials, or steering clear of several costs in general. If rival organizations in the country are incapable to lower their costs by a comparable quantity, Tesco will be capable of sustaining a competitive anchored cost leadership. Place: To develop its success in its retail operations, the Tesco should make multi-million pound investments in store expansion in low-income districts and localities. By getting involved with similar-minded public and private sector groups like local community based associations, colleges, and chambers of commerce, the Tesco will be able to open sites in economically disadvantage districts in china. Targeting these areas will enable the company to gain of local luminaries and gain favor from the local government by providing employment to the locals. Promotion: The Tescos approach should constitute a long-standing strategic plan that centers on generation value to expand the loyalty of their customer which takes account of preserving a well-built central Chinese business, to be as strapping in non-food as food product and services, to develop globally and to set the ball rolling on retailing services like on-line shopping. http://ivythesis.typepad.com/term_paper_topics/2009/08/tesco-marketing-mix.html (access-05-01-2010) The bottom-line is that object of the marketing mix is to satisfy the customer and in this analysis we can see place play most important roll in china situation. Because of that Tesco not catch that much success like UK or other place. Other hand tesco product price is contribute to get success of Tesco and for that in UK Tesco is a number one retail company. Different between domestic and international market There are eight main factors which is play the key roles to different between domestic and international market. The factor is below: Market size Market rate of growth Government regulation Economic and political factor Market share Product fit Contribution margin Market support (Marketing Today: Gordon Oliver 3rd edition; (1990) prentice hall Inter. (UK) limited. Hertfordshire) These are the key factor which is making different in global and domestic market. For example: In the case of Tesco, Malaysia, economic development condition, food supply chains are being rationalized according to more complicated major retail and food service consumers who wants to make business with fewer, larger, better-resourced manufacturers, suppliers and farmers. Therefore, power is polarizing the global retail industry. However Tesco has a long term business strategy in order increase profits, the company has three different dimensions in their strategies, and these are: corporate, functional and global or international. In this example we can see that how and why international marketing operation of Tesco deferent from domestic market operation. http://ivythesis.typepad.com/term_paper_topics/2009/11/strategic-marketing-tescopestleswotbcg.html (access-06-01-2010) Different marketing strategy of Tesco Tesco brought about o lot of changes in these marketing strategies and has grown to become UKs number one retailer. Today in the UK, the retailer has been dominant force more than 10 years-(Seth, A. Randall G., The Grocers: The Rise and Rise of the supermarket Chains). If we look in Tesco history we can see Tesco always change there strategy within time base and for that they get success constantly. In 1973 Lesile Porter and managing director lan MacLaurin applied one philosophy that is pile it high, sell it cheap which had left the company stagnating and with a bad image. In 1977 Tesco launched Operation Checkout which included the abandonment of green Shield stamps, price reductions and centralized buying for all stores. The result is a rise in market share of 4% in two month. 1990s In 1994 the company took over the supermarket chain William Low, successfully fighting off Sainsburys for control of the Dundee-based firm which operated 57 stores. Tesco introduced a loyalty card, branded Clubcard in 1995 and later an internet shopping service. In 1997 Tesco and Esco (part of Exxonmobil) forged a business alliance that included several petrol filling stations on lease from Esco, with Tesco operating the attached stores under the Express format. Ten years later over 600 Tesco/Esco stores can now be found across the UK. 2000s In October 2003 the company launched a UK telecoms division, comprising mobile and home phone service, to complement its existing internet service provider business. August 2004, it also launched a broadband service. In 2007 Tesco took part in a joint venture with O2 to from the Tesco Mobile virtual network operator in Ireland. In April 2009, Tesco announced that it had created a super tomato doesnt leak. We can see here that how Tesco change their strategy from beginning to until now. Other hand we can see Toscos almost entire relationship marketing strategy based on its Clubcard scheme. It has been able to use the Clubcard very effectively in addressing different customer segments and in attracting customers of all types. PESTEL Analysis http://www.learnmarketing.net/pestmarketing.jpg (access 17-12-09) PEST analysis shows the main external impacts of organization. PESTEL stands for political, economical, sociological, technological, ethical, and legal, in TESCO the following external will have great effects whether negatively or positively. Political: following the European integration and free trade Agreements, the market has opened up for British Companies to invest in Eastern Europe. Tesco already has 60 Hypermarket store in hungry. Economic: the Retail sector is fairly recession prawn and also very sensitive t change in interest rates. Since the events of September 11th the world economics have suffered heavily, stock plummeted and price is at all time lows. The world economy is however, now on the up post September 11th. Sociological: Change in consumer taste and lifestyle represent both opportunity and threats for the industry. Technological: change in retailing methods as such clothes sales via the internet is now a common place in retailing. Paperless operation, the management and administration of the company are undertaken on IT system, which are accessed through secure servers provide flexibility in the running of the business. Environmental: the threats are in terms of legal consequence for livestocks in terms of heath and safety. The renewal source of resource used in production, namely cotton and wool are environmentally friendly. Legal: the legal factor is national legislation for health and safety both in terms of consumer and also in terms of production of own natural renewable resource for making clothes. http://www.universitydissertations.com/Marketing/Tesco-Marketing-Strategy.php (access-07-01-2010) SWOT analysis of TESCO http://wc1.smartdraw.com/examples/content/Examples/06_Quality_Control/SWOT_Diagrams/SWOT_Diagram_-_Market_Analysis_L.jpg (access-07-01-2010) Strengths TESCO have secured commercial standing within the global market place wining Retailer of the Year 2008 at the World Retail Awards this can be used marketing campaigns to drive advantage towards the demographic base for future growth and sustainability. In an environment where global retail sales are showing decline or level performance on a like basis TESCO Group have published sales gain of 13% for UK markets and 26% growth in international markets. As a business looking for continued expansion TESCO have reserve funds of credit coupled with income derived from property portfolio development funds. Weaknesses TESCO finance profit levels were impacted through bad debt, credit card arrears and household insurance claims. TESCOs position as a price leader in UK markets can lead to reduced profit margins in order to retain the key price points on must have commercial items. Grocer outlets are not set up to operate as specialist in specific areas of product which can be capitalized on by other smaller bespoke retailer. Whilst current economic conditions suggest TESCO key value massage will succeeded there is a weakness in nonessential, mind to high ticket price items which will suffer from the rising cost of living and lower disposable incomes. Opportunities Statistics suggest TESCO is the third largest global grocer which indicates a level of buying power to ensure mainstream economies of scale. The acquisition of Homever provides the opportunity to develop the brand through Asia, specifically South Korea and further grow international markets for the group. The development of TESCO Direct through online and catalogue shopping will grow the use of technology, providing the launch pad for large non food based products with moderate to high margin returns and less focus on sale and margin per foot return to space. TESCO mobile have grown  ¼ million customer in 2008 and moved into profitable status suggesting further growth and development within this technological area can be developed. Threats UK and America markets have been affected by economic through the credit crunch Lower available income and strategic focus may need to change to lower priced basic products with less focus on higher priced brands suggesting a switch in price architecture. Rising raw material costs from both foods will impact profit margins overall. Changes to consumer buying behaviors require further analysis as technology develops consumers buying patterns change which will result in product areas requiring evaluation. For TESCO there is a persistent threat of takeover form the market leader Wal-Mart who has both means and motive to pursue such action. http://www.businessteacher.org.uk/business-resources/swot-analyis-database/tesco-swot-analysis/(access-07-01-2010) Another element of marketing mix People: People play c crucial role in the production and delivery of products and service. The physical presence of people performing the job is a vital aspect of customer satisfaction. The people mix issue: careful job selection careful policies of selection Institute programmers in staff training etc. Process: process involved the ways in which the markets task is achieved. The process mix: company policies accessibility service feature Capacity levels etc. Physical: The physical evidence relates to those aspects of the service provider that customer can see and fell so as to from an impression of the service or its provider. The physical evidence mix: logos colours equipment company vehicles labels Packaging etc. Three new marketing mixes also create importance in marketing. There fore Tescos marketing operation also effect by this new marketing mix. Conclusion Present time Tesco is the number one retail company in UK. They expand there business all over the world for example: China, India, Malaysia etc. TESCO have to understand that international marketing and domestic marketing both are complex process. Therefore they have to maintain their marketing progress and keep focusing on customer. In this report we try to show that how Tesco operate there marketing system, what is there aim, and what they can do. So TESCOs main objective is to take long term decision to make profit and also full-fill customer needs. Recommendation Based on this analysis we can say that TESCO doing vary well retail market in UK. Now they expand their business all over the world and for that TESCO need to care full about there marketing because different country has different type of customer and their needs also no same.

Global Warming - How Republicans are Endangering Our Earth Essay exampl

Imagine the world's major cities completely underwater. Imagine storms so violent that parts of the world became unlivable. Theses are images that one would expect to find in movie house, but environmental scientists tell us what is now a good setting for science fiction could soon be reality due to global warming. Environmental scientists warn that humans are not only making the Earth inhabitable for animals and plants, but that if humans continues with their current practices, the Earth will soon be inhabitable for humans as well. Environmental scientists warn that if the Earth's citizens do not act swiftly and decisively the damage maybe irreversible for humans.   American politicians have consistently rejected proposals for environmental reform. When President Clinton took office in 1993, he promised to become an environmental leader both internationally and nationally, and the proposals that he put to the floor of congress seemed to be the United States's first positive step toward reversing environmental policy. Unfortunately both his call to reduce greenhouse gases and to protect the world's biodiversity were blocked by Republicans in Congress. Since the Republicans have gained control of both the House of Representative and the Senate they have dramatically slashed and or eliminated the little environmental regulation that has taken place in the United States. 1   There clearly is a rift between environmental science and the Republican party, and it is this ideological divide that that is the largest threat to the future of environmental policy in the United States. Opponents of the GOP argue that Republicans are against environmental regulation because of their desire to protect businesses, while others argue that R... ...

Examine the factors affecting the domestic division of labour among couples Essay

The Division of Labour refers to the range of tasks within a social system. This can vary from everyone doing the same thing to each person having a specialised role. The division of domestic labour is the tasks given to each person in a house unit. For example the wife may do the housework, whilst the husband goes out to work. The division of domestic labour can also include childcare and emotion work, two things that previously were completely down to the wife but now are becoming more evenly spread between family members. Cultural factors that affect the division of labour are aspects like lagged adaptation. Jonathan Gershuny said wives who are in paid work do less housework (men do 27%), but the tasks are still sex-typed: men focus on DIY where as women cook. His explanation was there are gradual changes in values- known as lagged adaptation, and that over time parental role models will show children that men do housework too. Different ethnicities have different family structures- in many American families especially, the man is still the breadwinner and head of the household, while the wife cooks, cleans, and bears and raises children. Conjugal (marital) roles will vary depending on culture, if the society around a family typically has the man working then spending his leisure time with colleagues, that’s how that family will function because they are socialised that way. Some legal factors influence the division of labour, for instance it’s now easier and more socially acceptable for couples to get a divorce, so in a way there’s more pressure on men to keep things civil in the household. If the wife is unhappy, she can just leave. On the other hand, men and women don’t always have equal pay, which affects the division of labour as a popular belief in families is that the highest earner should do the least domestic work. Economic factors have had a significant impact on the division of labour,  ¾ of married/cohabiting women in the UK make money, which has resulted in ‘The New Man’. This is the idea that since women are bringing in an income, men are more willing to do domestic work. Rosemary Crompton pointed out that men do more in the home when the woman’s economical power increases (though the DOL is still unequal). However, women only earn  ¾ of what men earn, so men can never do quite as much housework based on their wives income. Feminists on the other hand feel that instead of a change in men, all that has altered is that women now bear a dual burden; this is the combination of paid work and domestic work. They believe modern men are benefiting from their wives’ financial income on top of them doing the housework and looking after the children. Lydia Morris found that even when the male partner is unemployed, the woman still does the domestic work as the male suffers a crisis of masculinity, so they refuse to demean themselves with housework. Women’s working hasn’t impacted on the division of childcare either; fewer than 4% of men were deemed the main child-carer in 1996. Additionally, Hochschild defined the concept of emotion work as a job where you manage someone’s emotions (for example an air stewardess). Feminists say women are working, looking after children/domestic labour, and are emotionally supporting the family. Jean Dunscombe and Dennis Marsden call this a triple shift (emotion work + domestic labour + paid work). So, in reality, the division of labour hasn’t changed through economic factors as much as perhaps it should have done. Many technological advances have made domestic labour easier, including effective contraception (the pill, implant and condom) as modern families are often smaller than in previous years. Most births are planned, and so the household is well prepared for the extra work. In addition, labour saving devices, like the Hoover and dish washer have resulted in men being more likely to help with housework as it’s now less time consuming and strenuous. Social factors that have influenced the division of labour include the lack of stigma attached to cohabiting couples; consequently they feel no pressure to get married. This could mean that gender roles aren’t as strictly enforced. Another important consideration is that in recent years, religion has become a less prominent aspect of life, a lot of families now won’t be religious at all and therefore don’t feel the need to treat each other a certain way as dictated by religion. Most social interaction of the current day can be traced back to religious codes of conduct, it’s possible than non-Christian societies expect wives to be treated differently to Christian ones. Theoretical perspectives such as functionalism and the new right support the division of labour. They state that families need segregated conjugal roles because it’s biological instinct and that it benefits everyone, they feel these marital roles help to organise the family. One functionalist, Talcott Parsons believed that males should take on an instrumental role; they should work and will be the ones to achieve success, while females should assume the expressive role (looking after the children, and catering for the emotional needs of the family). A popular view in right-wing politics, functionalism and the new right is that couples shouldn’t be equal, as the male should be the head of the family, while retaining the role of breadwinner. March of Progress sociologists (like Elizabeth Bott, Young and Willmott) argue the family is becoming more symmetrical with joint conjugal roles. These joint roles have become typical of working class life, in Young and Willmott’s opinions. Feminists like Ann Oakley disagree and say that segregated conjugal roles are socially constructed by men to benefit men as we still live in a patriarchal society. Her research found that men only have to do a small fraction of the domestic work for the household to qualify as symmetrical. This shows that although the UK advertises itself as a modern society, sexist views of the past are a frequent occurrence in our families.

Some tips she gave- Use AO2 phrases to show evaluation, and cite evidence to support perspectives. It is written in UK English. Apologies for any spelling errors and incorrect Sociologist names.)

Do You Know Your Student Rights

Do You Know Your Student Rights Did you know that college students have more freedoms than high schoolers? And, not just access to better parties and more free food. While you have the same rights to equality and non-discrimination that you had in high school, you have more protections for what you say, what you keep in your dorm, and who can arrest you. In honor of Human Rights Day, here are some of the lesser-known legal protections that you have as a college student. It might just inspire you to go out and take advantage of your newfound freedom. Your College Is Obliged to Keep Its Word Whatever a college prints or says is true, is really so. In the case of Andrà © v. Pace University (1996), the court found in favor of the complainant since she did not receive the advertised level of instruction as stated in the course catalog. The right to college integrity isn’t limited to written publications. Any person with the authority to make a verbal contract (such as a dean, admissions officer, recruiter, or academic counselor), is required to fulfill the terms. Such was the case in Healy vs. Larsson (1974). The complainant was awarded a degree based on a track of courses laid out verbally by his academic advisor, even though they didn’t meet the degree requirements. Protection From Search and Seizure The next time someone demands to see what’s in your dorm room, tell them they don’t have the right – because they don’t. In the 1971 case of Piazzola v. Watkins, the court found that college students don’t give up their right to unlawful search as seizure simply by signing a dorm room contract. In addition, only evidence found by a police officer with a legal warrant to search is admissible in court – and that doesn’t include campus cops. So, unless it’s a city or state police officer with a warrant, you don’t have to let anyone search your room. Control of Your Privacy Under the Family Rights and Privacy Act (FERPA), you have the same general privacy protections as any other citizen. However, if you are dependent on your parents’ taxes, your college has the right to send your grades directly to them. In addition, colleges have the right to publish information like your name, phone number, and address in a school directory (without your express permission) unless you specifically request for them not to publish that information. Right to Safety As a student, you have the right to be kept safe from campus injuries caused by facilities, other students, or foreseeable crime circumstances. For example, in the case of Miller v. State (1984), a college student was raped at knife point in her dorm because the school had failed to lock the doors for the night. She won her case, showing that the college has a special duty to protect its students, especially in areas where they make a claim that a student should be safe. Freedom of Speech and Demonstration Under the First Amendment, students are free to share their opinions through physical demonstrations, online activities, or through student groups. Papish v. University of Missouri (1973) clarified this language to include any speech that doesn’t interfere with the rights of other students or the school operation. This right especially protects students who are making statements on the school’s public message boards, intranet, or group publications. In Rosenberger v. University of Virginia(1995) the school was found at fault for refusing to distribute student group funds to a group that created a pro-Christian publication. Due Process If you are involved in a disciplinary action, you have the right to due process. That means you have the right to legal counsel, to view evidence against you, and to have a fair trial. The case of Texas Lightsey v. King (1983) showed that it is unconstitutional, for example, to expel a student for cheating when a disciplinary council finds him or her innocent of the act. So, if you get in trouble, make sure you get the fair trial you deserve. Summary From safety to scheduling, you have way more freedom than you think. Make sure you know your rights before you let your college take any away from you. It’s up to you to stand up and fight for your freedom to share your opinions, protect your privacy, and ensure that your college is everything you think it should be. Have your student rights ever been violated? Please share your stories and opinions in the comments below

The Top 10 French Gestures

The Top 10 French Gestures Gestures are frequently used when speaking French. Unfortunately, many gestures are not often taught in French classes. So enjoy the following very common hand gestures. Click on the name of the gesture, and youll see a page with an image of the relevant gesture. (You may have to scroll down to find it.) Some of these gestures involve touching other people, which is not surprising since the French are touchy-feely.  According to the French publication Le Figaro Madame (May 3, 2003), a study on heterosexual couples seated at a terrace established the number of contacts at 110 per half-hour, as compared to two for Americans. French Body Language in General For a full look at the intricacies of French body language, read the classic Beaux Gestes: A Guide to French Body Talk (1977) by Laurence Wylie,  Harvards longtime  C. Douglas Dillon Professor of French Civilization.  Among his telling conclusions: The French are  more controlled  (than Americans).  Their chest remains straight, their pelvis horizontal, their shoulders do not move and their arms are close to their body....There is something stiff and tense in the French way of moving.  This is why French clothes are too narrow, too tight for Americans.  Being very controlled with their bodies, the French need verbal expression as an outlet....Americans need more space to move.Your [the French] obsession with rationality leads you to give major importance to your head. The most characteristic French gestures are associated with the head: mouth, eyes, nose, etc. Of the dozens of iconic French gestures and facial expressions, the following 10 stand out as French cultural symbols. Note that these are not drawn-out affairs; they are done fairly quickly. 1.Faire la bise Greeting or saying goodbye to friends and family with a sweet (nonromantic) exchange of kisses is perhaps the most essential French gesture. In most parts of France, two cheeks are kissed, right cheek first. But in some regions, it can be three or four. Men do not seem to do this as often as women, but for the most part, everyone does it to everyone else, children included. La bise is more an air kiss; the lips do not touch the skin, although the cheeks can touch. Interestingly, this type of kiss is common in several cultures, yet many people associate it only with the French. 2.Bof Bof, aka the Gallic shrug, is stereotypically French. It is commonly a sign of indifference or disagreement, but it could also mean: Its not my fault, I dont know, I doubt it, I dont agree, or I dont care. Raise your shoulders, hold up your arms at the elbows with your palms facing out, stick out your lower lip, raise your eyebrows and say Bof! 3.Se serrer la main You can call this shaking hands (se serrer la main, or to shake hands) or the French handshake (la poignà ¨e de main, or  the handshake). Shaking hands is, of course, common in many countries, but the French way of doing it is an interesting variation. A French handshake is a single downward motion, firm, and brief.  Male friends, business associates, and coworkers shake hands when greeting and parting. 4.Un, deux, trois The French system of counting on the fingers is a bit different.  The French  start with the thumb for #1, while English speakers start with the index finger or the little finger. Incidentally, our gesture for loser means #2 to the French. Plus, if you order one espresso in a French cafà ©, youd hold up your thumb, not your index finger, as Americans would do. 5.Faire la moue The French pout is another oh-so-classic French gesture. To show discontent, distaste or another negative emotion, pucker up and push your lips forward, then squint your eyes and look bored. Voil la moue. This gesture shows up when the French have to wait for long periods, or they dont get their way. 6.Barrons-nous The French gesture for Lets get out of here! is very common, but its also familiar, so use it with care. Its also known as On se tire. To make this gesture, hold your hands out, palms down, and smack one hand down onto the other. 7.J'ai du nez When you tap the side of your nose with your index finger, youre saying that you are clever and quick-thinking, or youve done or said something smart. Jair du nez literally means that you have a good nose for sensing something. 8.Du fric This gesture means that something is very expensive, or that you need money. People sometimes also say du fric! when they make this gesture. Note that le fric is the French colloquial equivalent of dough, cash or money. To make the gesture, hold one hand up and slide your thumb back and forth across your fingertips. Everyone will understand. 9.Avoir une verre dans le nez This is a funny way to indicate that someone has had too much to drink or that person is slightly drunk. The origin of the gesture: a glass (une verre) symbolizes alcohol; the nose (le nez) becomes red when you drink too much. To produce this gesture, make a loose fist, twist it in front of your nose, then tilt your head to the other direction while saying, Il a une verre dans le nez. 10.Mon Å“il Americans express doubt or disbelief by saying, My foot! while the French use the eye. Mon oeil!  (My eye!) can also be translated as: Yeah, right! and No way! Make the gesture: With your index finger, pull down the bottom lid of one eye and say, Mon oeil!

The pros and cons of applying affirmative actions Essay

The pros and cons of applying affirmative actions - Essay Example This research will begin with the statement that affirmative action is often regarded as a policy concern towards discriminatory factors such as race, ethnicity, gender, religion, and sexual orientation. The present research has identified that the initial affirmative action was enacted in the United States under Executive Order 10925 by President John F. Kennedy on 6th March 1961. Furthermore, in 1965, President Lyndon B. Johnson executed the enactment of Executive Order 11246 focusing on the equal distribution of employment opportunities among various social classes and genders. The author has rightly presented that it was during the Second World War that discrimination amid the socio-economic context had emerged as a serious concern which led to the rising significance of equal rights, humanitarian approaches and various other social norms which aimed at facilitating proper distribution of resources in the community. Through this enactment, the application of Affirmative Action wa s aimed at mitigating unethical discriminatory practices in the fields of education, business and employment among others and thereby imbibing ethical concerns as well as justness within the society. This paper illustrates that since its initial application in 1961, the purpose of enacting the affirmative action had been to serve every religion and cast with equal opportunity in order to facilitate proper education and employment throughout the socio-economic context.... Accounting both the Pros and Cons of Applying Affirmative Actions From a generalized perspective, the affirmative action can be observed to guide a society towards equal distribution of wealth and development opportunities. Therefore, it is quite obvious that such policy concerns will motivate growth and thereby prove to be quite advantageous for the society. In this context, the benefits can be recognized as affirmative action tends to compensate minority interests, serve as a booster to social diversity and exposure platform to varied fields. By compensating minority interests in terms of education and employability, affirmative action facilities equal opportunities to various social classes, especially to those groups who are observed to avail limited exposure to national and global prospects owing to their restricted power and involvement in the society. Correspondingly, by serving as a booster to social diversity, affirmative action benefits as the community interests in terms o f equal distribution of salary and wages irrespective of the gender, race, ethnicity or any other discriminatory factor, precise and universal employment as well as educational norms which further facilitates the exposure of the society not only in the national but also in the international context. To be summarized, the most significant benefit of affirmative action can be identified as its role towards augmenting sustainable social growth (Holzer, and David, â€Å"Affirmative Action: What Do We Know†). Conversely, affirmative action can also be identified to impose crucial disadvantages towards societal development in the long-run. For instance, from a global perspective, affirmative action has often been accused to give rise to reverse

Educational Psychology Essay Example | Topics and Well Written Essays - 2250 words

Educational Psychology - Essay Example Educational psychology is worried with the procedure of educational achievement in the middle of the universal population and sub-populations such as talented children and those subject to precise disabilities (Woolfolk, A. & Margetts, K. 2007). Scenario 1: He’ll Speak to his Brain Andrew was a very slow writer. He constantly stared into space and was easily distracted and yet didn’t admit he had a problem. Miss O’Brien has spoken to his previous teacher, who said he was lazy. Miss O’Brien believed that a lot of Andrew’s behaviour was linked to being afraid of getting it â€Å"wrong† and she had her suspicions that pressure came from home. She developed a strong relationship with Andrew and he eventually admitted to her that he had a problem with his writing. One day when Miss O’Brien was working with Andrew, she asked him why he couldn’t write what was in his head. He said, â€Å"When I get up to five things in my head they burst like a bubble - it’s like trying to pick up a bubble, when you touch it, it bursts.† It was a real insight into Andrew. He had just shown her how able he was at using and controlling language to capture his thoughts and feelings. He had identified his short-term memory problems. After that Andrew really unburdened himself saying that he was anxious that Mum and Dad might realise he has a problem and he believed himself that he couldn’t write. Together Miss O’Brien and Andrew devised three ways to help. First, they had a book of ideas which Andrew could carry around and when he saw or did something interesting he could make a note of it.

Final report - Essay Example The target audiences of the kit is both children and adults. To facilitate the programming of the kit, a programming language referred to as NXT has been developed by LEGO. This programming language gives everyone the ability to possess full control of the Lego Mindstorm Kit (Valk). The use of this programming language if efficient even for people who lack programming language skills. This project is aimed at constructing a programming a robot that has the ability to pick balls from the ground, carry the ball for at least one meter following a black line drawn on the ground and place the ball in a container 0.50 metres high. A LEGOÂ ® MINDSTORMSÂ ® NXT 2.0 kit will be utilized in building and programing the robot. The choice of this kit among other robotics platform was very carefully chosen due to various reasons. The kit fulfilled several requirements. This requirements are; it has an architecture which has made able to be programmed efficiently at different complexity levels. Moreover, the kit is exploitable at many levels of complexity. And finally, it’s simple yet equipped with robust functionality which are expandable. The equipment also has several advantages which include very short start – up time, the setup process does not involve electrical wiring, among other advantages. Lego Mindstorm NXT, which is a kit used to program robots, is dated back to 2001 when it was released by LEGO (Nguyen). The kit is advantageous over other robotic programming kits since it has the ability to interact efficiently with the outside world by use of input and output sensors. Moreover, Lego Mindstorm platform has the powerful ability to support a wide variety of sensors which include the EOPD sensors, the compass sensors, the Acceleration sensors, the Gyroscope sensors among many others. With this sensors, the developed robot is able to harvest signals from the environment in order to carry out the predefined tasks. To

Editing Research Paper - Essay Example The onset of the so-called global village has necessitated the need for students to acquire an international experience, so as to be able to function as career men and women in a world that is rapidly becoming more and more interlinked. The notion of a â€Å"global perspective† has replaced the old global dream of a â€Å"world order.† The global village perspective emphasizes interdependence among all the nations of the world. Numerous new concepts serve as evidence of international interdependence that today’s students cannot avoid. These include the competitive pressures that have resulted due to globalization of economies, the linguistic and cultural challenges encountered in international business, the massive impact of 9/11 that the world feels to this day, international environmental challenges such as the negative ecological effect of global warming, and technologically facilitated telephonic and internet communications. Since the end of the Second World War, interactions and activities that essentially took place within the borders of a single state are increasingly taking place across national boundaries. Examples include business relationships, employment, professional associations, and family and social connections. This ongoing process of globalization has presented new pressures to individuals to competently engage in the free flow of commerce, communication, and ideas across national boundaries. To this effect, studying abroad serves as a way of preparing students to function effectively in this globalized society (Williamson 28-32). The advantages of studying abroad outweigh the disadvantages. The world is becoming increasingly globalized; therefore, studying in a foreign country is beneficial because it enables students to learn new languages and cultures, obtain exposure which widens their level of thinking, and learn to

Business Planning and Development Essay Example | Topics and Well Written Essays - 1750 words

Business Planning and Development - Essay Example The company mainly operates in Asia, Europe and North America with its headquarters in New York. Research and analysis has shown that PVH currently has high level of debt and interest payments which is reflected in its high debt-to-equity ratio (showing that the company is highly geared). Furthermore, the company has a relatively small, concentrated customer base, intense competition which could lead to volatility in earnings and an underfunded pension plan. Therefore, it is increasingly important for PVH to secure its market position and reduce its dependence on debt rather than increasing it. Discussion Liquidity It is important to analyze the financial liquidity of PVH in order to ascertain its ability to take on more debt. The current ratio of a company reflects its ability to take on short term debts or debts within a period of 12 months (Baker & Powell, 2005). Usually a current ratio of PVH’s current ratio is 2.39 (NASDAQ, 2013) which reflects that for every $2.39 of cur rent assets, the company has $1 of current liabilities. Normally, companies having a current ratio over 1 are considered to have strong liquidity position or ability to pay off short term debts (Weil et al., 2012). This is visible in the case of PVH. Although the short term liquidity of PVH seems to be high (as indicated in the research), its long term liquidity remains very weak. Furthermore, the high current ratio may not be a good indication as a review of PVH’s Balance Sheet shows that majority of its current assets (almost a third of the dollar value) are tied up in inventory which indicates a major problem. This is because inventory may take time to convert to cash and may, therefore, negatively affect the company’s ability to pay off its short term liabilities (Ross et al., 2012). Therefore, the high liquidity indicated by the high current ratio may, in effect, be insignificant because of too much inventory being held. Furthermore, PVH’s cash flow stateme nt indicates a positive operating cash flow of 453m which, in itself (Yahoo! Finance, 2013), indicates a high level of cash availability and liquidity. However, the relevant figure in this case is not operating cash flow but levered free cash flow as the latter takes interest on debt into account. In short, levered free cash flow indicates a cash position of a firm after it pays off the interest on its debt (Penman, 2009) . This is a negative value (-45m) for PVH (Yahoo! Finance, 2013) which indicates high interest payments and suggests that the cash generated may not be sufficient to ensure continuity of the business in future. Debt position PVH’s financial position indicates an already high level of long term debt as a percentage of its total liabilities (roughly 58%). Furthermore, it is important to understand the financial leverage of PVH in order to further determine its ability take on the additional ?20 million. This is explained by the total debt to equity ratio which describes the relative proportion of debt and equity that the firm uses for financing its assets (Heitger et al., 2008). A higher ratio typically suggests an aggressive growth strategy with the effect of increased earnings, albeit often with high interest charges. Normally, a debt-to-equity ratio over 20% is not considered a healthy sign (NASDAQ, 2013). The total debt to equity ratio of PVH is very high (108.65) which suggests that the company is highly geared (NASDAQ, 2013). This already high debt indicates the high interest cha

Why Do We Need To Eat Healthy Essay Example | Topics and Well Written Essays - 750 words

Why Do We Need To Eat Healthy - Essay Example Healthy eating does not in any way mean any sort of diet; it actually refers to the proper intake of healthy foods like meat, vegetables, fruits, and nuts, whole grains etc in balanced proportions. All these will provide us with the required amount of carbohydrates, fats and vitamins and minerals and never induce any health problem when taken moderately. Firstly, there is a need to eat healthy to avoid serious diseases. Regardless of the age, healthy eating habits have a crucial impact on our health. Long standing studies have established a definite link between diet and cardiovascular diseases. Cases of coronary heart disease are on the rise and the cardiovascular morbidity figures are staggering. Studies have made it clear the high amount of fat intake, particularly LDL or low density lipoprotein and triglycerides, increases the chances of developing coronary diseases like atherosclerosis. On the other hand a diet that provides you with a good amount of HDL can help decrease the ch olesterol levels in the body. High fiber grains can help lower chances of heart disease and type 2 diabetes ( F.B Hu and Willet, 2002).Decrease in cholesterol levels itself has a lot of good impact on the body- chances of CVD (cardio vascular diseases) are lowered, blood sugar and hyper tension problems are also controlled. Dietary fat also increases the risk of developing certain types of cancer like breast cancer, esophageal, stomach and prostate cancer and has been supported by animal studies too. Most forms of cancers, have been linked to obesity and lack of proper nutrition and according to the National Cancer Institute, most of these cancer forms are preventable. Immunity is one of the basic tools for survival. Humans are immune to many pathogens simply because of the presence of white blood cells like NK cells in the body, which engulf the antigen and protect the body from harm. In case human did not have this immunity barrier, they would become vulnerable to all diseases and may even die owing to even small and minor infections. The key to a strong immune system is an intake of healthy diet. Colas, pizzas, burgers do not increase immunity in anyway. But intake of healthy foods like vegetables and fruits provides beta-carotene which in turn strengthens the body. In recent studies cancer experts have also found out that healthy eating and strong immunity also prevent development of certain cancers. There are a number of diseases that are caused due to nutritional deficiencies. Nutritional deficiencies occur when proper balanced food is not ingested. Beriberi, pellagra, scurvy, rickets, Ariboflavinosis, Skin diseases, Hypocobalaminemia, Paraesthesia and night blindness are some of the diseases related to vitamin deficiency. Painful chronic Gouty arthritis is another dreadful disease caused by bad eating habits. Deficiency of essential minerals like calcium, magnesium, iron, sodium etc leads to diseases. If proper healthy habits are not developed a person will from health problems Scientific studies have shown that our mental health also depends on dietary factors. Minor depression, major depression, psychotic depression, traumatic disorders, stress disorders, compulsive behaviors, and anxiety are some of the mental problems that haunt a person. Though most of these diseases depend on genetic, biological and psychological factors but studies have determined that foods rich in omega-3 fatty acids ,release serotonins in the brain which in turn elevates mood.

Painful chronic Gouty arthritis is another dreadful disease caused by bad eating habits. Deficiency of essential minerals like calcium, magnesium, iron, sodium etc leads to diseases. If proper healthy habits are not developed a person will from health problems Scientific studies have shown that our mental health also depends on dietary factors. Minor depression, major depression, psychotic depression, traumatic disorders, stress disorders, compulsive behaviors, and anxiety are some of the mental problems that haunt a person. Though most of these diseases depend on genetic, biological and psychological factors but studies have determined that foods rich in omega-3 fatty acids ,release serotonins in the brain which in turn elevates mood.

Herbal Medicine Essay Example for Free

Herbal Medicine Essay Anything that exists on the earth has a need for survival. According to the World Health Organization (WHO), herbal medicines refers to health practices, approaches, knowledge and beliefs incorporating plant, animal and mineral based medicines, spiritual therapies, manual techniques and exercises, applied singularly or in combination to treat, diagnose and prevent illnesses or to maintain well-being. Different types of herbal medicines are widely applied in Asia, Africa, and Latin America to meet primary health-care needs. Herbal medicines have maintained its popularity in most regions of the developing world. The application is also rapidly spreading in industrialized countries. Worldwide, among all the different traditional medicine systems, Traditional Chinese medicine (TCM) is currently the most popular, followed by Indian medicine. Herbal medicine refers to using a plants seeds, berries, roots, leaves, bark, or flowers for medicinal purposes. Herbalism has a long tradition of use outside of conventional medicine. It is also called botanical medicine or phytomedicine. It is becoming more main stream as improvements in analysis and quality control along with advances in clinical research show the value of herbal medicine in the treating and preventing disease. Herbal medicine is used to treat many conditions, such as asthma, eczema, premenstrual syndrome, rheumatoid arthritis, migraine, menopausal symptoms, chronic fatigue, irritable bowel syndrome, and cancer, among others. Herbal supplements are best taken under the guidance of a trained health care provider. Recently, the World Health Organization estimated that 80% of people worldwide rely on herbal medicines for some part of their primary health care. In Germany, about 600 700 plant based medicines are available and are prescribed by some 70% of German physicians. In the past 20 years in the United States, public dissatisfaction with the cost of prescription medications, combined with an interest in returning to natural or organic remedies, has led to an increase in herbal medicine use. Whenever a culture attempts to assimilate alien ideas, social stresses are bound to occur, especially when such ideas threaten the dominion of major economic and political interests. Mistakes are likely to arise while attempting to implement these ideas. In the case of Chinese herbal knowledge, its use by people unfamiliar with its rules and protocols invariably leads to mishaps; either the herbs or formulas fail to work as expected, or worse, side effects may result whenever herbs are used in contraindicated conditions. In the political and economic realms, government regulators unfamiliar with the unique characteristics of traditional Chinese medicine may impose restrictions upon Chinese herbal practice that inhibit its effective application and suffocate its future development within our culture. The effectiveness of modern herbal practice suggests that we begin our search by understanding the complete meaning of herbalism. Herbs are grown and collected from all over the world. There is nothing magical about an herb; effective medicinal herbs can be found everywhere that plants grow. There is indeed a necessity in making life better by introducing natural herbal dietary supplements in the country. Within the past decade, herbal medicine has gained increasing importance, with both medical and economic implications. In developing countries particularly, as much as 80percent of the indigenous population still depends on traditional systems of medicine and medicinal plants for healthcare. Some common herbs and their uses are discussed below. * Ginkgo (Ginkgo biloba) has been used in traditional medicine to treat circulatory disorders and enhance memory. Although not all studies agree, ginkgo may be especially effective in treating dementia (including Alzheimers disease) and intermittent claudication (poor circulation in the legs). * Kava kava (Piper methysticum) is said to elevate mood, enhance well-being and contentment, and produce a feeling of relaxation. Several studies have found that kava may be useful in the treatment of anxiety, insomnia, and related nervous disorders. * Saw palmetto (Serenoa repens) is used by more than 2 million men in the United States for the treatment of benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland. A number of studies suggest that the herb is effective for treating symptoms, including frequent urination, having trouble starting or maintaining urination, and needing to urinate during the night. * Valerian (Valeriana officinalis) is a popular alternative to commonly prescribed medications for sleep problems because it is considered to be both safe and gentle. * Echinacea preparations (from Echinacea purpurea and other Echinacea species) may improve the bodys natural immunity. Echinacea is one of the most commonly used herbal products, but studies are mixed as to whether it can help prevent or treat colds. We chose to have a research study on this topic because I think this can be a way of spreading awareness among people that there can be cheaper way of treating from upset stomachs to headaches. They are also considered natural and therefore healthier and gentler than conventional drugs. So, why is there need to spend so much on expensive drugs uselessly when there is a better option.

Analysis of Unified Modelling Language

Analysis of Unified Modelling Language Chapter 1: Introduction Context of the Problem The Unified Modeling Language is a graphical modeling language used for the visualization, specification, construction, and documentation of object-oriented software systems. It has been adopted by the Object Management Group (OMG) and is widely accepted as a standard in industry and research. The UML provides thirteen types of diagrams for different purpose. This thesis focuses on sequence and class diagram known as structure diagram and behavior diagram. Sequence forms concentrate on the presentation of dynamic aspects of a software system, and class forms the structural view of software system. Sequence diagrams stress time ordering while Class focus on static. In Model-driven Architecture (MDA), class diagram is the source for code generation in object-oriented development (Pender, 2003), so how to map what we find in the interaction diagram back to class diagram become an important subject if we want to develop system from behavior aspect initially. There are some existing relatively modest tool supports exploiting the logical dependencies of UML diagrams. Some systems maintain method lists across class diagrams and sequence diagrams and the transformation between sequence diagrams and collaboration diagrams. However, nowadays, the two diagrams that sequence and Class are draw divided and can not be transformed between each other. And there is no comprehensive framework that would support such mechanisms throughout these two diagram types in a systematic way (Selonen et al., 2003). That waste much time to maintain system and often make the system development documents should rewrite again and again. To solve these problems, a transformation theorem which proposed by Selonen et al. (2003) is cited in this paper. Selonen et al. (2003) propose a framework and categorize meaningful transformation operations between different diagram types in UML. These operations can be used, for example, for model checking, merging, slicing and synthesis (Selonen et al., 2003). The transformation operation can be used as a basis of tool support in UML-based modeling tools. With these operations, we can get the benefits as follows: Class Diagram becomes easier and faster to create because they can be achieved as results of automated operations. Class Diagram becomes more consistent and correct because they are either produced or updated automatically, or checked against each other exploiting the transformation operations. Improve the software development process. The process of agile modeling become from use case to sequence diagram and then translated to class diagram. It will be more simply and efficiency. Research Question and sub-questions How does the transformation between sequence and Class diagrams make systems easier to develop and maintain and avoid system development documents to be rewritten all the time? What are meta-modeling, Meta Object Facility and Object Constraint language? How to operate the transformation? How does the transformation work in the real world (Examples)? Significance of the Study Sequence diagrams provide a natural and easy medium for designing the examples of typical dynamic interactions of objects, often as refined representations of use cases. After modeling examples of interactions, the designer should add the information implied by the sequence diagrams to the static view (class diagrams), or check that the static view conforms to the sequence diagrams (Selonen et al., 2000). The sequence diagram and class diagram derived from the same use case and can not be transformed between each other. This paper discusses a particular UML transformation operation mentioned in (Selonen et al., 2003), which transforms from a sequence diagram into a class diagram. The transformation operation is based on the UML 2.0 Specification (OMG, 2003), which defines the syntax and semantics of UML. The thesis defines the rules on the phases of this transformation operation and gives a transformation example to show the result of transformation. This paper will concentrate on the conceptual research of UML semantics, and do not concentrate on any development tool. However, OCL will be used to describe the transformation rules and hoped can be used in UML-based modeling tools development. I hope that the steps of modeling will improve; Support for synthesizing a new class diagram from an existing sequence diagram can provide significant help for the designer. Such synthesis operation helps the designer keep the two diagrams consistent because the synthesized class diagram can be compared with existing class diagram. The transformation operation also speeds up the design process, and to decrease the risk of human errors. In UML CASE tool vendors can implement this transformation operation in their tools to get the benefits described above. Research Design and Methodology The protocol for this research project is mostly using qualitative by design. A Case study will be used as the most important a strategy of research methodology in the study. The research process consists of six steps. It collects and analysis the documents and papers which are corresponding to the UML transformation thesis, OCL and MDA transformation theory. Then proposing a transformation framework for transformation from sequence diagram to class diagram and concluding transformation mapping rules. This paper will testify and revise the transformation mapping rules via implement a real case of agile modeling development process. And finally proposing the research result, and discuss the conclusion and future work. Organization of the Study Chapter 1: Introduction Chapter one introduces the research. This chapter will present the context of the problem, the problem statement, the main research question, the significance of the study, and the research methodology used to address the main research question. Chapter 2: Review of the Literature Chapter two gives an overview of the background literature for the thesis. Chapter 3: Meta-modeling, Meta Object Facility and Object Constraint language Chapter three will give the brief introduction of UML, MDA, meta-model, transformation and OCL are described at first, followed are the separate meta-models of sequence and class diagram. Chapter 4: Operation of the Transformation Chapter four will propose a framework of transformation from Sequence diagram to Class diagram. Also, a rule will be defined on every phase of transformation, using OCL to describe transformation rules. Chapter 5: Example of the Translations Chapter five will be working on a Case Study, and demonstrating the transformation for a true case in the real world. Chapter 6: Conclusion Chapter six will present the summery and conclusion. Chapter 2: Review of Literature 2.1 UML The complexity in software development process of getting from a set of requirements to a proper abstraction of the solution leads people to develop models. A model is a simplification of something so we can view, manipulate, and reason about it, and so help us understand the complexity inherent in the subject under study (Mellor et al., 2004). The UML is a family of graphical notations, backed by single meta-model, that help in describing and designing software systems, particularly software systems built using the object-oriented (OO) style (Fowler, 2003). The Unified Modeling Language (UML), since adopted as a standard (UML 1.1) by OMG in 1997, has become a widely accepted as standard for modeling a software system. The latest UML version 2.0 has been formally adopted in June 2003, and it will be applied throughout this thesis. UML 2 describes 13 official diagram types which fall in two categories depending on whether they describe structural or behavioral aspects of a software system. The UML can capture an array of processes and structures which related to business and software. UML has such power that a modeler can use it for the general architecture of any construction that has both a static structure and dynamic behavior. A project can rely on UML as the standard language to express requirements, system design, deployment instructions, and code structure (Eriksson et al., 2004). 2.2 Agile Modeling Test case modeling and an evolutionary approach are two major and strongly related techniques to model transformation (Rumpe, 2004). UML nowadays has become popular modeling language for software intensive systems used. Models can be used for a variety of purposes. One advantage of using models for test case description is the application specific parts which are modeled with UML-diagrams, such as connection to frameworks, error handling, persistence, or communication are handled by the parameterized code generator (Rumpe, 2004). This allows us to develop models which can be independent of any technology or platform, such as PIM. When the technology changes, we only need to update the generator, and the application defining models can directly be reused. This concept also directly supports the above mentioned MDA-Approach (OMG, 2005) of the OMG. Another important merit is that both of the production code and automatically executable tests are modeled by the same UML diagrams. Therefore developers could use a single homogeneous language to describe implementation and tests. This will enhance the availability of tests at the beginning of the coding activities. Analogously to the â€Å"test first approach† (Beck, 2001), sequence diagrams are used for test cases and can be taken from the previously modeled requirements. When we start software modeling by drawing classes in a class diagram does not mean we are developing a class model. Instead, we are developing a software model by defining static aspects through a static view. If we start our development by drawing a dynamic diagram, like the state or sequence diagram, we are developing a software model by defining dynamic aspects through a dynamic view. The class and sequence diagrams could better be called structural and dynamic views. They are all written in the same language: UML (Kleppe et al, 2003). In Agile modeling (Ambler, 2002), we develop an Information system in following steps by using UML. System Use Case Models UI Prototypes UML Class Diagrams UML Sequence Diagrams UML Activity Diagrams Use case diagram shows a number of external actors and their connection to the use cases that the system provides. A use case is a description of a functionality (a specific usage of the system) that the system provides. The description of the actual use case is normally done in plain text or as a document linked to the use case. The functionality and flow can also be described using an activity diagram. The use case description only views the system behavior as the user perceives it and does not describe how the functionality is provided inside the system. Use cases define the functional requirements of the system. Sequence diagrams address an interaction and may be used to model flows within use cases (Booch et al., 1999). They show how the objects interact to execute operations, emphasis on the time ordering of the messages. Class diagrams shows a collection of declarative (static) model elements, such as classes, types, and their contents and relationships. Once we have the use cases, the next step is to create the class diagram. This is the heart of the object-oriented model. This paper concentrates on the steps of modeling from Use Case Models to Class Diagrams and sequence Diagrams. 2.3 MDA The MDA is a new software engineering approach developed and published by the Object Management Group (OMG). One fundamental observation in the evolution of living software systems over the years is that their basic design models are mostly unchanged. Most changes to evolving software systems take place only at engineering level, forced by the introduction of new technologies and platforms (BAohme et al., 2005). MDA promotes simply the usage of models for the whole software system development. To capture the problem of technology evolution MDA defines two categories of models. The first one is for abstract modeling of the software systems at the design level. This model class is called Platform Independent Model (PIM). The second category is related to specific platforms and technologies. It contains mainly engineering aspects of the software system and is called Platform Specific Model (PSM). Between these two classes of models, MDA defines a relation in the form of several transformations, which ensure the structural equivalence of PIM and PSM. Another key issue of MDA is a technology framework for different kinds of model handling (storage, exchange, mapping of models, etc.). The Meta Object Facility (MOF) (OMG, 2000) is convenient for this purpose. Historically modeling languages were defined by abstract grammars. MOF instead defines modeling languages on the base of so-called Meta-Models. Meta-Models are models (instances) of built-in MOF concepts. Using this framework the developer can focus more on the definition of mappings between models rather than having to struggle with ordinary model handling. This is due to the fact that MOF comes with a method for the definition of model classes (Meta-Models) and for the exchange of models using the XML Metadata Interchange (XMI). In addition, MOF provides mappings of Meta-Models to repository interfaces as well. Such a repository holds all necessary information about model instances. The above argument is correct for most of todays component technology. To show the real application we have to choose concrete Meta-Models for PIM and PSM. This also leads to the selection of appropriate Meta-Models and notations for PIM and PSM. One requirement for both is the support of the component concept as a first class concept. Moreover, the Meta-Model for the PSM should be part of a well-defined and established component technology. Because the spread industrial usage is a process consuming several years, the suitable technologies have traditional syntax based languages for component definition. MDA exploits the emergence of a class of tools, which support model translation and allow meta-model manipulation. Meta-models are models of the formalism used to build models. They define the various kinds of contained model elements and the way they are arranged, related and constrained. The process of developing a model results in the creation of instances of the model elements defined in the meta-model – the meta-model is â€Å"populated† with instance data. Model transformation is the process of converting a model expressed in one formalism to another model of the same system expressed using a different formalism. This can be achieved by building a meta-model of each of the source and target model representations and then defining a mapping between them. The meta-model of the source model is populated with instance data of the specific source model to be transformed. The mapping rules are applied as a set of operations invoked on the source meta-model, which results in a meta-model of the target model populated with instance data. This populated target meta-model is then used to generate the target model (or possibly the target text in the case of code generation. (Bloomfield, 2005) 2.4 Models, modeling, and MDA Models and model-driven software development are at the heart of the MDA approach. So it is appropriate to start by looking at what is being practiced when enterprise application developers take advantage of modeling. In the software engineering world, modeling has a rich tradition from the earliest days of programming. The most recent innovations have focused on notations and tools that allow users to express system perspectives of value to software architects and developers in ways that are readily mapped into the programming language code that can be compiled for a particular operating system platform. The current state of this practice employs the Unified Modeling Language (UML) as the primary modeling notation (Rumbaugh et al.,1999). The UML allows development teams to capture a variety of important characteristics of a system in corresponding models. Transformations among these models are primarily manual, with tool support for managing traceability and dependency relationships among modeling elements, supported by best practice guidance on how to maintain synchronized models as part of a large-scale development effort. One useful way to characterize current practice is to look at the different ways in which the models are synchronized with the source code. Each category identifies a particular use of models in assisting software practitioners to create running applications (code) for a specific runtime platform, and the relationship between the models and the code. Today, most of software developers still take a code-only approach, and do not use separately defined models at all. They rely almost entirely on the code they write, and they express their model of the system they are building directly in a 3rd generation programming language such as Java, C++, or C# within an Integrated Development Environment (IDE) such as IBM WebSphere Studio, Eclipse, and Microsoft VisualStudio. Any â€Å"modeling† they do is in the form of programming abstractions embedded in the code (e.g., packages, modules, interfaces, etc.), which are managed through mechanisms such as program libraries and object hierarchies. Any separate modeling of architectural designs is informal and intuitive, and lives on whiteboards, in PowerPoint sides, or in the developers’ heads. While this may be adequate for individuals and very small teams, this approach makes it difficult to understand key characteristics of the system among the details of the implementation of the business logic. Furthermore, it becomes much more difficult to manage the evolution of these solutions as their scale and complexity increases, as the system evolves over time, or when the original members of the design team are not directly accessible to the team maintaining the system. An addition is to provide code visualizations in some appropriate modeling notation. As developers create or analyze an application, they often want to visualize the code through some graphical notation that aids their understanding of the code’s structure or behavior. It may also be possible to manipulate the graphical notation as an alternative to editing the text based code, so that the visual rendering becomes a direct representation of the code. Such rendering is sometimes called a code model, or an implementation model, although many feel it more appropriate to call these artifacts â€Å"diagrams† and reserve the use of â€Å"model† for higher levels of abstraction. Some tools that allow such diagrams (e.g., IBM Web Sphere Studio and Borland Together/J), the code view and the model view can be displayed simultaneously; as the developer manipulates either view the other is immediately synchronized with it. In this approach, the diagrams are tightly coupled representations of the code and provide an alternative way to view and possibly edit at the code level. Further advantage of the models can be taken through roundtrip engineering (RTE) between an abstract model of the system describing the system architecture or design, and the code. The developer typically elaborates the system design to some level of detail, then creating a first-pass implementation from the code generated by applying model-to-code transformations, usually manually. For instance, one team working on the high level design provides design models to the team working on the implementation (perhaps simply by printing out model diagrams, or providing the implementation team some files containing the models). The implementation team converts this abstract, high-level design into a detailed set of design models and the programming language implementation. Iterations of these representations will occur as errors and their corrections are made in either the design or the code. Consequently, without considerable discipline, the abstract models and the implementation models usually and quickly – end up out of step. Tools can automate the initial transformation, and can help to keep the design and implementation models in step as they evolve. Typically the tools generate code stubs from the design models that the user has to further refine. As changes are made to the code they must at some point be reconciled with the original model. To achieve this some approach to recognize generated versus user defined code is used such as placing markers in the code. Tools adopting this approach, such as IBM Rational Rose, can offer multiple transformation services supporting RTE between models and different implementation languages. In a model-centric approach, models of the system are established in sufficient detail that the full implementation of the system can be generated from the models themselves. To achieve this, the models may include, for example, representations of the persistent and non persistent data, business logic, and presentation elements. Any integration to legacy data and services may require that the interfaces to those elements are also modeled. In some cases much more than code stubs can be generated depending on the fidelity of the models of patterns to transform the models to code, frequently allowing the developer some choice in the patterns that are applied (e.g., among various deployment topologies). To further assist in the code generation, this approach frequently makes use of standard or proprietary application frameworks and runtime services that ease the code generation task by constraining the styles of applications that can be generated. Hence, tools using this approach typically specialize in the generation of particular styles of applications (e.g., IBM Rational Rose Technical Developer for real-time embedded systems). However, in all cases the models are the primary artifact created and manipulated by developers. A model-only approach is at the far-right end of the modeling spectrum. In this approach developers use models purely as thought aids in understanding the business or solution domain, or for analyzing the architecture of a proposed solution. Models are frequently used as the basis for discussion, communication, and analysis among teams within a single organization, or across multi-organizational projects. These models frequently appear in proposals for new work, or adorn the walls of offices and cubes in software labs everywhere as a way of understanding some complex domain of interest, and establishing a shared vocabulary and set of concepts among disparate teams. In practice the implementation of a system, whether from scratch or updating an existing solution, may be practically disconnected from the models. An interesting example of this approach can be seen in the growing number of organizations who outsource implementation and maintenance of their systems while maintaining contr ol of the overall enterprise architecture. 2.5 Transformations between UML diagrams UML provides different diagram types supporting the development process from requirements specification to implementation (Selonen et al., 2001). The models presented by different diagrams view a system from different perspectives or from different abstraction levels. Therefore, the various UML models of the same system are not independent specifications but strongly overlapping: they depend on each other in many ways. For Instance, changes in one model may imply changes in another, and a large portion of one model may be synthesized on the basis of another model. So far there exists relatively modest tool support exploiting the logical dependencies of UML models. Some systems (e.g. Rational Rose) maintain, for instance, method lists across class diagrams and sequence diagrams: adding a call of a new method in a sequence diagram automatically causes the corresponding updating of the class symbol in a class diagram. Another example is the transformation between sequence diagrams and collaboration diagrams, also supported by Rational Rose. However, there is no comprehensive framework that would support such mechanisms throughout Class diagram and Sequence diagram in a systematic way. This paper studies the relationships of Class diagram and Sequence diagram in UML, and transformation operations that are based on those relationships. A transformation operation takes a UML diagram as its operand (the source diagram), and produces another diagram of another type as its result (the target diagram). It considers such transformation operations as an essential part of a UML- based software design environment. The transformation operations can be used for example in the following ways: Model checking:Are two diagrams consistent with each other? It is much easier to find inconsistencies between two diagrams of the same type than between two diagrams of different types. If the diagrams are of different types, transformation operations can be first applied to obtain two diagrams of the same type, which are then compared for consistency. Model merging:Add the information contained in one diagram to another diagram. Merging the modeling information of two diagrams is much easier when the diagrams are of the same type (Alanen and Porres, 2003). If the diagrams are of different types, transformation operations can be first applied to obtain two diagrams of the same type, which are then merged. Model slicing:Create a partial view of a diagram showing only a particular aspect. Often the aspect can be presented in the form of another diagram (of some other type). For example, one may want to see a dynamic slice of a static diagram. The diagram representing the slicing criterion (for example, a dynamic diagram) can be first transformed into the type of the target diagram (for example, a static diagram). An intersection of the two diagrams of the same type then shows the desired slice. Model synthesis:Produce a diagram on the basis of an existing diagram of another type. This is the most straightforward usage of transformation operations. Such synthesis can be useful for two purposes: to obtain automatically an initial form of a diagram needed in a subsequent phase of the software development process, or to obtain a different view of the information contained by a diagram. The latter may be used just as a transient view on a model, rather than as a persistent design artifact. 2.6 Phase of Transformation Operation Selonen et al. (2003) use the UML meta-model to define the transformation between UML diagrams. Since diagram types are only very loosely defined (the same notation may represent different meaning on different diagrams), we need to establish a precise mapping from a graphical view representing a diagram type to a model; i.e. we must define a model that corresponds to a given diagram. This model contains exactly the logical information exposed by the diagram, needed by the transformation operations. We will call this model the minimal model of the diagram. As we do this for all diagram types, we are able to define transformations between diagram types as functions from the meta-model of a diagram type to the meta-model of another diagram type. Such a function takes the minimal model of the source diagram as its argument, and produces the minimal model of the target diagram. They call the transformation rules the interpretation of the transformation. Assuming that the mappings from the source diagram into its minimal model, from this minimal model into the minimal model of the target diagram, and finally into the target diagram, are all defined uniquely, the transformation between two diagram types becomes fully defined (Selonen et al.,2003). First, take a given sequence diagram and map the sequence diagram to its minimal model. Then transform this minimal model to a minimal model of a class diagram. Finally, this minimal model is mapping to a class diagram in model level. This thesis will base on this process to introduce a definite transformation operation. Reference Tom Pender. (2003).
