Marketing Functions in Organization - 1571 Words

jhcakfjswwwwMARKETING AND ITS FUNCTIONS Marketing has a connective function in society. It connects supply and demand or production and consumption. At micro-level, marketing builds and maintains the relationship between producer and consumer. At business unit level, marketing can have an integrative function. It integrates all the functions and parts of a company to serve the markets. The narrowest definition is to see marketing as a function of a business enterprise between production and markets taking care that products move smoothly from production to customers. 2.2. The societal function of marketing In modern society production and consumption are apart from each other. Marketing connects them. From the societal point of view,†¦show more content†¦For a marketing system to be operative and effective, there are three general types of functions which it must provide. †¢ Exchange functions: - buying - selling - pricing. †¢ Physical functions: - assembling - transport and handling - storage - processing and packaging - grading and standardisation. †¢ Facilitating functions: - financing and risk-bearing - market information - demand and supply creation - market research. Exchange functions are what is commonly thought of as marketing. They involve finding a buyer or a seller, negotiating price and transferring ownership (but not necessarily physical transfer). These functions take place at the market - that is, the physical meeting point for buyers and sellers at the point of production or via some other means of communication. At this point, formal or informal property rights are important to ensure the reliable transfer of ownership and to guarantee legality (e.g. that animals on sale were not stolen and will not be reclaimed). Physical functions enable the actual flow of commodities through space and time from producer to consumer and their transformation to a form desirable to the consumer. Assemblying or concentrating the product at convenient points allows its economical transport (i.e. getting enough animals together to transport cheaply). This is a valuable function which is often overlooked in the public perception of traders.

Successful adaptation to change Involves risk taking which means that the inevitability of unpredictable outcomes, both positive and negative leaves many individuals lost in fear and pain. While some find contentment in familiar family and friends, others find change confronting, causing feelings of fear and insecurity, while still others seek the thrill of exploration. In spite of these varying attitudes to change, change is a concept that is essential to the continuation of life. We will write a custom essay sample on Djas or any similar topic only for you Order Now These varying concepts of change and Its Importance are represented through structural and language techniques. In the poem ‘Loch Arid Gorge’ by John Fouler, a poem that refers to the thrill and dangers of naval exploration. The feature film ‘Rush’ directed by Ron Howard, conveys the fear resulting from injury and the positive change that can come from suffering. Finally, the poem ‘Enter Without So Much as Knocking’ by Bruce Dade tests the reader’s own understanding of the negative effects of commercialism change on human life. Whilst the positive thrill of exploration and risk taking involves new worlds and perspectives, the negative aspects when disaster strikes well outweigh the positive effects. Such journeys may include other people such as the way that Australian poet John Fouler explores the notion of change via thrill of exploration, as well as the discovery of the past. Fouler creates a relationship between himself and the responder through the use of Inclusive language within the text. This Is conveyed In â€Å"We climb along a weathered cream precipice†¦ † The use of Inclusive language takes the responder on a dangerous journey along the cliff face with the author to the setting where the poem is taking place. The Journey Fouler shares with responders pens their eyes, revealing the tragic historical past and the violent events that had taken place along the Victorian coastline. With the realization of the shipwreck of the Lock Arid ‘a century ago, the true strength and persistence of nature Is revealed as It simply goes on *clicking tufts of unconcern’ Like the sheep and cattle’, the unusual metaphor here together with the gravestones’ that ‘hump the grass’ reveal Just how much has changed physically at this tourist site since that terrible night. Moreover, nature’s power to provide negative unpredictable outcomes reveals the risk of sea runners in the past. Change is perceived by the reader as both, positive and negative resulting in the responders Joining Fouler as he takes them on an exploration to discover the unfamiliar secrets of history. This idea of risk taking and unpredictable outcomes is also represented in the film ‘Rush’ which involves the highly dangerous sport of Formula One in sass’s. The protagonists cheat death and get thrill from it which is represented in the quote, â€Å"The closer you are to death, the more alive you feel. It’s a wonderful way to live. † which describes risk taking with positive connotations. This is reinforced by the way the director capture the protagonists crash. The use of a long shot down the straight they are sitting on the straight watching the scene take place. The heavy rain droplets running down the screen emphasis the dangers and how heroic the drivers are. When the car flips many components from the vehicle fly off in every direction illustrating how dangerous the sport was, not only for the driver and the car but for the audience who are at risk of projectiles from crashing cars. This crash hanged the Fl culture forever, it encouraged drivers never to push racing to extreme limits where conditions are likely to result in great injury or death. Both of these texts demonstrate the thrill that some find in risk taking. However, this text also demonstrates the dangers in the exploration of new situations. Since change is unpredictable, individuals often experience pain and suffering which negatively affects their lives but also has the potential to encourage personal growth and understanding as they struggle to adapt. This is explored in ‘Rush’ as Howard explores both change and the positive and negative thoughts of fear which arise from injury and suffering. Suffering forces individuals to take stock of their lives ,†Ã¢â‚¬ ¦ While in Hospital getting my lungs vacuumed I realized there was more than Just winning, I have a wife and want to live till a long age†¦. â€Å", the use of personal first person reflection and the black humor of’ getting my lungs vacuumed’ makes the character, Nikkei Laud, exaggerate his feelings towards the positive aspects of life and how much he values it. The use of the flashbacks to where Laud was in hospital unconnected to all the medical equipment show the true terror all bystanders experienced. A close up shot from the doctor pushing the vacuum down his throat as well as the strong sound of sludge being sucked from his lungs, turns the responder stomach to almost feeling the smallest of pain Laud experienced during his recovery. The director included the direct and confronting image in the film to express how the positive outcomes of change only become obvious after fear of injury and suffering. Enter without so much as knocking is a poem written by Bruce Dade in order to test he reader’s opinion towards change and question the inevitability of change through the broad range of language techniques used. The parody of sass advertising slogans in the quote â€Å"†¦ Like every other well-equipped smoothly-run household, his included one economy size mum, one Anthony Squires-Cholesterol-summertime Dad†¦ † Enfor ces the influence of consumerism on society as it manipulates people to change without them being aware of it. This is seen through the use of caesura and tone to reinforce the thoughts of shallow commercialism and its strong influence on change. The overload of commercialism is perceived as topic but is only changing the world into a dyspepsia society as it large influences the actions and products of each and every individual. This tests the reader’s thoughts of change and why they have changes. Throughout all three texts composers take their responders on a Journey to demonstrate their perspectives of change. In ‘Loch Arid Gorge’ and ‘Rush’ the composers express factual historical events. The composers take their responders on social, cultural and personal changes and the impact on human life. Those personae quire adaptation and often risk taking behavior in order to understand themselves better. By contrast, â€Å"Enter without so much of knocking reveals that change can be subtle as the persona is not aware of the changes until it is too late and he is faced with death. Intro: risk taking – different perspective unpredictable outcomes: positive and negative inevitability, no control expressed through engage and structural techniques ‘Loch Arid Gorge’ by John Fouler: destruction caused by nature ‘Rush’ by Ron Howard: fear resulting from injury and the positive change that can come from offering ‘Enter Without So Much as Knocking by Bruce Dade: negative effects of commercialism on human life.

Israel has many coastal plains, several mountains, Essay Example For Students

Israel has many coastal plains, several mountains, Essay and hills. The Coastal plains run parallel to the Mediterranean Sea and is made up of beaches, bordered by fertile land. In the north, there are sandy beaches and sandstone cliffs that drop to the sea. The coastal plain is home to over half of Israels population. The coastal plains also house most of Israels industry. Several mountain ranges run through Israel. In the northeast, are the Golan Heights, which were formed by volcanic eruptions. The hills of Galilee, made of limestone, reach to heights ranging from 1,600 to 4,000 feet above sea level. Small streams and little rainfall keep the area fertile. People, who live in Galilee and the Golan, work in agriculture, tourism-related jobs, and industry. The rolling hills of Samaria and Judea present rocky hilltops and fertile valleys dotted with age-old olive groves. The hillsides, first developed by farmers in ancient times, blend into the natural landscape. The population is mainly found in small urban areasand large villages. Continuing south, the region becomes an area of bare peaks, craters and plateaus, where the climate is drier and the mountains are higher. The northern areas of Israel are extremely fertile, while the southern part issemi-arid. Agriculture, fishing, light industry and tourism make up the areas mainsources of income. The Jordan River, flows north to south with a 186 mile route. It then empties into the Dead Sea. The river is usually narrow and shallow.

The average annual rainfall is less than one inch and summer temperatures soar to 104 F. The Dead Sea, the lowest point on earth at about 1,300 feet below sea level, lies at the southern end of the Jordan Valley. Its waters have the highest level of salinity in the world. The Dead Sea is rich in potasium, magnesium and bromine, as well as table salts.

Abstract Essays - Culture, Linguistic Typology, Southeast Asia

Abstract Essays - Culture, Linguistic Typology, Southeast Asia Abstract Introduction S ome eleven languages and eighty-seven dialects were spoken in the Philippines in the late 1980s. Eight of these Tagalog , Cebuano, Ilocano, Hiligaynon, Bicolano , Waray-W aray , Pampangan , and Pangasinan were native tongues for about 90 percent of the population. All eight belong to the Malay-Polynesian language family and are related to Indonesian and Malay, but no two are mutually comprehensible. Each has a number of dialects and all have impressive literary traditions, especially Tagalog , Cebuano, and Ilocano. Some of the languages have closer affinity than others. It is easier for Ilocanos and Pangasinans to learn each other's language than to learn any of the other six. Likewise, speakers of major Visayan Island languagesCebuano, Ilongo , and Waray-Waray find it easier to communicate with each other than with Tagalogs , Ilocanos , or others. Language divisions were nowhere more apparent than in the continuing public debate over national language. The government in 1974 initiated a policy of gradually phasing out English in schools, business, and government, and replacing it with Pilipino, based on the Tagalog language of central and southern Luzon. Pilipino had spread throughout the nation, the mass media, and the school system. In 1990 President Corazon Aquino ordered that all government offices use Pilipino as a medium of communication, and 200 college executives asked that Pilipino be the main medium of college instruction rather than English. Government and educational leaders hoped that Pilipino would be in general use throughout the archipelago by the end of the century. By that time, it might have enough grass-roots support in non- Tagalog -speaking regions to become a national language. In the early l990s, however, Filipinos had not accepted a national language at the expense of their regional langua ges. Nor was there complete agreement that regional languages should be subordinated to a national language based on Tagalog . The role of English was also debated. Some argued that English was essential to economic progress because it opened the Philippines to communication with the rest of the world, facilitated foreign commerce, and made Filipinos desirable employees for international firms both in the Philippines and abroad. Despite census reports that nearly 65 percent of the populace claimed some understanding of English, as of the early 1990s competence in English appeared to have deteriorated. Groups also debated whether " Filipinization " and the resulting shifting of the language toward " Taglish " (a mixture of Tagalog and English) had made the language less useful as a medium of international communication. Major newspapers in the early 1990s, however, were in English, English language movies were popular, and English was often used in advertisements. Successful Filipinos were likely to continue to be competent in Pilipino and English. Speakers of another regional language would most likely continue to use that language at home, Pilipino in ordinary conversation in the cities, and English for commerce, government, and international relations. Both Pilipino, gaining use in the media, and English continued in the 1990s to be the languages of education.

HRM Term Paper on ADA Essays - Free Essays, Term Papers

HRM Term Paper on ADA Essays - Free Essays, Term Papers HRM Term Paper on ADA Introduction On July 26, 1990, the Americans with Disabilities Act was signed into law with the intent to make the American workplace more accessible to people with disabilities. It was signed by former president George H.W Bush, who said ?I know there may have been concerns that the ADA may be too vague or too costly, or may lead endlessly to litigation. But I want to reassure you right now that my administration and the United States Congress have carefully crafted this Act. We've all been determined to ensure that it gives flexibility, particularly in terms of the timetable of implementation; and we've been committed to containing the costs that may be incurred.... Let the shameful wall of exclusion finally come tumbling down It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on race, religion, sex, national origin, and other characteristics illegal. According to the most recent text of the ADA, which was amended in 2008, the definition of disability is ?a physical or mental impairment that substantially limits one or more major life activities of such individual; a record of such an impairment; or being regarded as having such an impairment? (www.ada.gov). This further protects individuals with disabilities in recruitment, screening, hiring, promotions, layoffs and termination, and any other terms or conditions of employment. Private employers, state and local governments, employment agencies, and labor unions are covered in the act. In addition, the ADA applies to all aspects of participation in society, including employment, public accommodations, transportation, and telecommunications. The ADA prepares employees by providing appropriate information and personnel training on the provisions of the ADA, its relevance to the functioning of the organization as a whole, and the responsibilities of specific personnel. The ADA is also undergoing continuous review and interpreta tion in the courts. Many people have set themselves up as experts on the ADA. They believe that they are experts on how to remove architectural barriers, how to build a ramp or refit a bathroom to comply with ADA standards. Unfortunately in too many cases, the so-called experts do not know about the ADA standards and their errors have been costly to people who relied on their help. There are no certificates or licenses for the ADA and those who claim that they are certified or licensed ADA experts are not telling the truth. The best advice is to consult your local Center for Independent Living and use reputable architects and builders who are familiar with ADA architectural standards and requirements. This is the best way to prevent a costly and lengthy lawsuit. Brief History The ADA is the most comprehensive federal civil rights legislation protecting the rights of people with disabilities. Passed by the United States Congress in 1990, the ADA addresses the barriers and discrimination that people with disabilities have traditionally faced. The legislature covers access to employment, state and local government programs and services, access to places of public accommodations, transportation, non-profits service providers and telecommunications. The ADA has been amended several times since its passage in 1990, with the most recent amendment in 2008, which became effective on January 1st, 2009. Purpose of the ADA The purpose of the Americans with Disabilities Act is ?to provide a clear and comprehensive national mandate for the elimination of discrimination against individuals with disabilities; to provide clear, strong, consistent, enforceable standards addressing discrimination against individuals with disabilities; to ensure that the Federal Government plays a central role in enforcing the standards established on behalf of individuals with disabilities; and to invoke the sweep of congressional authority, including the power to enforce the fourteenth amendment and to regulate commerce, in order to address the major areas of discrimination faced day-to-day by people with disabilities.? (www.ada.gov/pubs) Title I The Americans with Disabilities Act is divided into five titles, employment being the first. Title I became effective July 26, 1992 for employees of 25 or more workers and July 26, 1994 for employees with 15 or more workers. Title I is enforced by the Equal Employment Opportunity Commission (EEOC). This title states that businesses must provide reasonable accommodations to protect the rights of qualified individuals with disabilities in all aspects of

When the system requires from a person to perform a certain task with which he/she disagrees, he is either loyal to the moral standards or to the system; keeping in mind that loyalty is also a moral standard. Why did Milgram’s subject obey and shock the learner? Or less specifically why do people obey authorities even when the orders involve harm to another person? (Meyer, J, 1997) to find the logical reasons and to see them from psychological aspect, this search helped a great deal. Several people were tested psychologically to see the reactions and obedience level in the presence of legitimate authority. Not only they subsided the moral or ethical obligations but also continued to follow commands to inflict pain on an innocent person. Though many of them were not in favor of what they did to the learner but they seem incapable of protesting the wrong. Most of them were dealing with an inside fight which was visible through their gestures and body language but the ability to deny the wrong was less likely seen during the experiment. The common misinterpretation was observed in all the teachers (subjects) was sympathy within is irrelevant unless it changed into action to perform moral obligation. Similarly the control of any government can be seen through action and thus is effective, when performing the action requires to. People in the experiment disvalued their actions but were unable to assemble the inner courage to depict their values into action. The resul ts explained the behaviors of Hitler’s army, who obeyed him and continued the process of torture and killings of million. Milgram’s experiments tested several people.

Analyze why people are so passionate about sports Essay

Analyze why people are so passionate about sports - Essay Example The craze about football, for instance, is common knowledge to fans and non-fans alike. People have passion in sports for the love of it, but most importantly, because it is enjoyable, entertaining and relaxing. The level of passion in football is quite high. Many are the instances when fans express dejection and anger when their favourite teams succumb to defeat. Passionate fans will go mad when they hear the words â€Å"after all, it was just a game.† Those who have no idea how painful it is to lose a game speak such statements. Probably they are not aware that football is a source of inspiration for most people just as books are to others. Passionate fans revere their players and teams. To them, nothing is as sweet as their teams getting to the top of the rankings where the smell of victory is strongest. English Premier League (EPL) fans are known to express this kind of passion. Some end up committing suicide following massive losses. Football games are an integral part of passionate fans. It is quite annoying to hear comments like â€Å"what is the fuss all about?† Anyway, it is wrong to blame people who have little understanding of passion or emotions. Vallerand et al. (1279) argue that there may be differences in modes of expressing passion across the world but the football language remains one. This language makes passionate fans similar in a number of ways These similarities best explain why people may be passionate about football. Living the experience of football is the most essential requirement of being a passionate fan. Mere spectating does not suffice. One has to be part of the whole experience. A passionate fan has to attend most of his or her team’s matches. My father once shocked me when he said, â€Å"If I miss a Chelsea game I may not concentrate at work for a week or so.† Moreover, being a passionate fan invites the duty of emotional engagement with the team to make the team perform well. However, fans who attend away

Thus, vapour compression processes are perfect for treating the industrial water. as, mechanical vapour compression produces water with the highest quality and is more energy efficient as compared to the thermal vapour compression, it is suitable for the industrial water treatment of the given composition. As, the water has a pH showing the more concentration of basic ions, it is important to acid acidic ions to precipitate the basic ions. Oxygen and nitrosamines are added to convert the NH3 into NO2 that is good for the plants or can be extracted easily from water through next process. The Phenols can be removed by utilizing the active carbons and UV oxidation. The treatment of the thio-cyanate can be controlled by utilizing alkaline chlorination and ozonation. NaNO2 can be removed by utilizing the sulfamic acid, which reduces the NaNO2 to nitrogen gas that can be collected or released to the atmosphere. Bacteria can be added to the water to eat COD and produce bio gas that can be used to produce power for the plant. Calcium or aluminum ions can be added to reduce the amount of PO4 in waste water. The next step would be the purification of industrial waste water through the mechanical vapour compression. Mechanical vapour compression gives the same purification as that of the distilled water and utilized the similar procedure for the purification. There is essential to utilize the high density platinum steel in the compression chamber that would

A Study Of Lewins Model Management Essay

A Study Of Lewins Model Management Essay In the refreezing stage the company stabilized changes by establishing systems that can establish behavioural pattern in the organisation. A new performance appraisal system based on behaviour and results was introduced to encourage customer service. (Goodstein., D., L. Burke, W., W., 1991) 14 It is not easy for an organisation change its structure and business processes since any change may lead to some level of resistance by the employees. One of the main causes for resistance is the fear of the unknown and loss of what is familiar. There are four reasons of resistance from employee to organisational change including 1) Parochial self-interest, 2) Misunderstanding and lack of trust, 3) Contradictory assessments, and 4) Low tolerance for change. (Buchanan D. Huczynski A., 2004) BA tried to change behaviour by changing the management style from authoritative to participative. BA wished employees participate more in management decision but since this was unfamiliar employers would fall back to the old patterns. 15 A tactic that was used in BA to manage resistance to change was the HR policy which included training guidelines. Such an HR policy is important in making the employees understand and react positively to change. There is also an example where resistance to change hindered the organisations goals and objectives. In an attempt to cut down cost can compete with low cost airlines BA tried implementing a new payment system and also hiring workers for lower salaries. This created insecurity among the employees which ended in a strike that cost the company in millions in 2000. Therefore handling resistance and the HR aspects of the company is vital to a successful change process. 15 REFERENCES 16 Wilson, C.D., (1992), A Strategy of Change, Thomas Learning, London 16 British Airways, 2006, Leaders For Business: What are we looking for?, http://www.britishairwaysjobs.com/baweb1/?newms=info196 (22 December 2006) British Airways, 2006, Our Recruitment Process: The Assessment Process, http://www.britishairwaysjobs.com/baweb1/?newms=info48 (22 December 2006) 16 Paton, R.A.

Change management According to cook et al (2004) change management is a set of processes that is employed to ensure that significant changes are implemented in an orderly, controlled and systematic fashion to effect organizational change. One of the goals of change management is to reduce resistance to change in order for organizational members accept the change and thereby achieve the organizations goal of a smooth transformation. Change management can be seen to have five specific stages that must be realized for an organisation to be successfully implementing change. Firstly the organisation must know why a specific change or series should be brought about. Secondly the organisation must be motivated and desire to go through this particular change. Thirdly the organisation must posses the knowledge of how to carry out the change. Fourthly the organisation must acquire new skills and behaviours that are necessary for the change to occur. Lastly the organisation must become sustainable by making these new behaviours their usual practice. Further according to Wilson (1992) change can occur mainly in two dimensions depending on the theories and models used. This view explains that change can be either planned or unplanned. Also change can be described in terms of the process or implementation strategy. The issues of understanding and managing change within an organisation depend on the change approach that is selected by the organisation. Organisational Structure British Airways operates as a group of companies whose main industry sectors are international and domestic scheduled and charter air services carrying passengers, freight and mail as well as providing supplementary services. The group consists of British Airways Plc and a number of subsidiary companies, including British Airways Holidays Ltd, British Airways Travel Shops Ltd etc. The two main operating bases of the company are Heathrow and Gatwick airports and has established in branches around the world. The company is listed in several stock exchanges including LSE, Munich, US etc. British airways together with its partnerships have managed to extend its network thus entering all significant markets. As for the structure of BA, it has suffered a shift from modern to post modern to post modern organisational structure i.e. it has moved from mechanistic to more organic style of operation. The operations of BA can be analysed departmentally into Planning, Distribution and mileage partnerships, Marketing communications, Global contact centres, eCommerce, Triton Programme, Revenue management, AirMiles Travel Company, Travel Shops, BA Holidays, BA travel Clinics, Corporate communications, BA world Cargo, Ground Operations, BA engineering, Information management, BA shares etc. Each division has its own functionalities to perform, goals and objectives to meet which contributes to corporate aims and objectives. Department Responsibility Planning Planning fleet, network, schedule, infrastructure, resources, property Distribution mileage partnerships Ensure that customers can book pay and ticket a booking through the website, contact centres, shops, travel agents around the world Marketing communications Marketing communications, advertising, promotions, gain insight into customer needs Global contact centres Delivers services to customers who prefer using the phone eCommerce Major projects to broaden the range of transactions customers can do on their own, improve quality of online channels Triton Programme The 10 year contract with Amadeus, leading provider of travel industry systems Revenue management Monitors, controls, forecasts sales working to improve profitability AirMiles Travel Company Carries out customer loyalty programmes Travel Shops Provides personal services and expert advise from well travelled consultants BA Holidays Sells holiday packages travel Clinics Offers travel health advice and comprehensive vaccination service Corporate communications Protects and manages the global reputation ensuring that a wide audience are aware of the airlines news and developments. world Cargo Provides freight, mail and courier services Ground Operations Management of Customer services and terminal operations with safety and security Engineering Responsible for aviation maintenance providing full support for the fleets Information Management Responsible for all IT across the BA group and plays a fundamental role in shaping the future of the airline BA shares Responsible for all investor relations Table 1: Departmental Analysis of British Airways Market Environment PEST Analysis The Airline industry has become extremely competitive due to the budget airline and the current unfavourable economic conditions. All player compete for the market share in an environment where the bargaining powers of customer have increased and there is no control over the powers of fuel suppliers and prices. In the current economic conditions there is limited growth in volume and demand for air travel has declined significantly. The PEST analysis shows the external factors that affect the organisation and its change processes. It also reveals the changes the organisation must make in order to remain competitive in adverse market conditions. Thus, this section looks into the external environment of British Airways since change strategies are affected by the factors and changes in the macro environment. Such changes could bring about favourable or adverse effects on the companys turnover and growth. The PESTEL framework has been applied to examine the external factors and its impact on the company. Political and Legal Factors Developments in the political and legal factors can have a high impact on the airline industry. Political developments include changes in governmental policies, international regulations and legislations, government taxes on air travel, political and economical relationships with counties, changes in airport and aviation rules etc. Some of the developments have a favourable impact on the company while some others will have an unfavourable impact. The EU policy has increased air travel and therefore has been a positive impact on the airline industry. On the other hand, increase of government taxes has adverse results on the industry since demand for air travel declines due to high airfare. Economical Factors Economic developments such as increase in fuel prices, unfavourable currency and interest rates, recession, inflation, increase in unemployment has a negative impact on British Airways. In such environments leisure travel declines because people have less disposable income and business travel declines because corporate spending is reduced. Also recession negatively impacts on growth of companies in terms of expansions and buying additional aircrafts. On the other hand, changes such as economic boom, deflation could favourably contribute towards a companys performance. Social and Environmental Factors Airline industry is constantly under pressure for various environmental pressure groups due to high CO emission, noise and the effects on the climate. Also outbreaks of diseases such as such as Swine Flu can decrease air travel. Another aspect that could reduce air travel is safety related issues such as acts of terrorists and crashes. Technological Factors Changes in technology have shown negative and positive impacts on the airline industry. The positive impacts have been safety, cost reduction and ease of booking and planning travel online. On the other hand due to new technological developments such as advanced meeting facilities business travel is not necessary to the same extent as before. BA and Ryanair British Airways aims to operate a high quality service to its customers at a affordable price. It operates long and short haul flights to many destinations around the world and ensures comfort while taking the passengers closer to their destination. British airways mainly operate in three areas, namely passenger transport, cargo and mail services. British airways aim to understand its customers needs and operate accordingly. The company has a strong brand image and the employees are expected to work up to its standards. The organisational structure can be regarded as a flat type because it has only one level of hierarchy that separates Managing Directors at the top from bottom-line employees. On the other hand Ryanair operates on a no- frill strategy which means that the passengers are not provided with any extra facilities and operates simply as a point to point transportation service. It has grown largely in Europe by attracting customers who prefer low ticket prices thereby reducing the market share of British Airways. It mainly operates short haul flights to destinations which are secondary airports. Factors Affecting Change Management According to Paton and McCalman (2008) Change management can be defined as a planned process for changing a core function or organization of an enterprise. Change Management is an organized, systematic application of the knowledge, tools, and resources of change that provides organizations with a key process to achieve their business strategy. (Lamarsh 2000). With the aid of technology the industries and products are congregating which means each firm has to take a very holistic approach to the marketing of goods and services. Paton McCalman (2000). Factors driving change Most organisations change when internal and external environments change. The factors that initiate the need for organisational change can be two fold. The first factor can be called an External Trigger which involves the activities and innovations of competitors, change in customer requirements, legislation and government policies, and so on. Economic change can create the need for change. Also, due to the EU policies many companies had to change their practices and procedures. Environmental pressure groups that impose pressure due to adverse environmental effects can force a company such as BA to change its processes to make it climate friendly. The second factor can be called the Internal Triggers including new product and service design, innovations, appointments of new directors, new ideas on how to achieve service quality etc (Buchanan D. Huczynski A., 2004). The British Airways privatization program that changed the companys ownership was launched due to the impact from such triggers. The aims and objectives of this programme was to improve the organisations performance and gain a competitive advantage over its competitors. According to the change model described by Lewin, organisational change occurs in three stages. The first stage is called Unfreezing which reduces the forces which maintain behaviour as it is currently and recognition of the need for change occurs. The second stage is called Movement which is the development of new practices and the implementation of the change. The final stage is named as Refreezing which is stabilizing the changes that occurred and reinforcement through supporting mechanisms. (Mul lins, J., L., 1999) Involving People It is essential that the organisation manages its human resources in a manner that is favourable to the change process. It is important that the employees understand and support the change in order to have a smooth transformation. If the change managers can make the people involved to see the common objectives and mutual benefits that the change will bring about it helps in making the change more successful (Paton McCalum, 2000). However, each individual will react to change in a different manner. The factors that affect how individuals will react to change are manifold, namely the organisational culture, the reasons for change, factors of change, leadership aspects and organisational structure. The change management style and approach are important aspects with regards to involving the employees of the organisation. Change management requires a considerable amount of skill and previous experience on the management of the organisation. It is important to consider each individuals pe rception and attitude towards the process for it to be a success. For example during the second stage of change, BA developed tactics and programs to bring the vision of the top management-level to the bottom-line employees throughout the organisation. Thus the internal structure and systems were changed and also a permanent training center was established to promote staff training. Stakeholders It is important that the company analyses its stakeholders since the change will have an effect on them. Communication is vital to involve all stakeholders in the process so that the change is successful. It is also important to categorise your stakeholders according to their power and interest involving the change. There are some aspects regarding stakeholders and the change process that should be taken into consideration. Differentiating and grouping employees and deciding how to deal with different types, planning communication in both directions and also looking after the interests off all individuals. There are mainly four types of stakeholders, blockers, sponsors, champions and sleepers Green (2007). Blocker have high power but low level of commitment, while the sponsors have high power and high commitment. Also Champions have high energy and high commitment while sleppers have both low power and low commitment to change. For a successful change it is important to identify the stakeholders with high power and commitment. British Airways has a number of stakeholders who have various interests in the business and from whom the company expects different things. There have been conflicts between these stakeholders due to their differing interests as well as formations of coalitions. It can be observed that most stakeholders have an interest in the organisation performing well. In the above context it is important that the stakeholders are analysed according to the power and commitment grid so that change can be successful. Planning the change The change process must be planned and it is advisable to use models of change and also consider the impacts of resistance to change. Two different change models are discussed in the following section, namely the Mckinsey 7-S model and Lewins Model. The basic principle of the model is that there are seven internal aspects of an organization that need to be aligned if it is to be successful. The 7S model can be used in a wide variety of situations such as improving the performance of the company. The McKinsey 7S model contains seven interdependent factors which are categorised as hard or soft elements. Hard elements are strategy, structure, systems and soft elements are shared values, skills, style and staff. The Hard elements are easier to identify and influence while the soft elements are more difficult to manage but equally important for a successful transformation. The model depicts the interdependencies of these elements in terms of how a change in one element affects the others. According to the model the seven elements must be aligned. In the case of BA, the model can be used to identify what needs to be realigned to improve performance during other changes in the company. What ever the change is this model can be used to understand the interrelationships. Further it can be used to analyse the current position, proposed position and identify the gaps between the two. It is also necessary to adjust these elements to make sure the company works effectively. Now lets examine Lewins change model. According to Lewin, there are three stages of change in an organisation which are unfreezing, movement, and refreezing. Unfreezing Stage accordingly, the first step for BA is to unfreeze present pattern of behaviour to manage resistance. In this stage change did make an impact on individual level due to the implementation of Downsizing of Workforce policy to restructure the organisation. This policy reduced hierarchy, and allowed worked to be carried out easily thus improving performance. (Shibata., K., 1993) The downsizing was achieved through compassion. BA also introduced training programs such as Putting People First to help line managers and workers understand the change and the requirements of the industry. Movement Stage The second stage of Lewins Model is movement. During this stage BA used tactics and programs to bring the vision of the top management and line employees. In support a number of new systems where implemented. (Goodstein., D., L. Burke, W., W., 1991) Refreezing Stage In the refreezing stage the company stabilized changes by establishing systems that can establish behavioural pattern in the organisation. A new performance appraisal system based on behaviour and results was introduced to encourage customer service. (Goodstein., D., L. Burke, W., W., 1991) Resistance to change It is not easy for an organisation change its structure and business processes since any change may lead to some level of resistance by the employees. One of the main causes for resistance is the fear of the unknown and loss of what is familiar. There are four reasons of resistance from employee to organisational change including 1) Parochial self-interest, 2) Misunderstanding and lack of trust, 3) Contradictory assessments, and 4) Low tolerance for change. (Buchanan D. Huczynski A., 2004) BA tried to change behaviour by changing the management style from authoritative to participative. BA wished employees participate more in management decision but since this was unfamiliar employers would fall back to the old patterns. A tactic that was used in BA to manage resistance to change was the HR policy which included training guidelines. Such an HR policy is important in making the employees understand and react positively to change. There is also an example where resistance to change hindered the organisations goals and objectives. In an attempt to cut down cost can compete with low cost airlines BA tried implementing a new payment system and also hiring workers for lower salaries. This created insecurity among the employees which ended in a strike that cost the company in millions in 2000. Therefore handling resistance and the HR aspects of the company is vital to a successful change process.

Awake and Sing by Clifford Odet versus A Raisin in the Sun by Lorraine

Clifford Odet's play, "Awake and Sing", and Lorraine Hansberry's play, "A Raisin in the Sun", both revolve around the struggle of attaining the American dream during the hardships of a struggling economy and most important the value of a family. By analyzing the main characters, Ralph and Walter, it can be seen that even though they wish to use the insurance money to fulfill their dream they eventually realize that with family they can survive through poverty. Both characters are being weighed down by poverty. This brings them to dream of the life they could live if one was giving a chance "to get to first base" and the other a chance to open up a liquor store. Ralph doesn't really seem to be interested in his family at first and is only interested in his own advancement from all his hard work. He wishes he could afford a pair of shoelaces and "a pair of black and white shoes." Ralph is only thinking of himself and how he and his girl can live together. That is where "life begins" for him. Walter also wants to see advancement, but for both him and his family even if it ...

Anorexia, Meet Orthorexia

Anorexia, Meet Orthorexia Anorexia, Meet Orthorexia Anorexia, Meet Orthorexia By Maeve Maddox The other evening I heard the word orthorexia for the first time. Its a newly coined word meaning Excessive concern with consuming a diet considered to be correct in some respect, often involving the elimination of foods or food groups supposed to be harmful to health. On the pattern of anorexia nervosa, one may now speak of orthorexia nervosa, a pathological concern with consuming a correct diet. The word anorexia has been around since 1598 with the meaning lack of appetite. An extreme form of anorexia is anorexia nervosa: pathological loss of appetite from psychic causes typically accompanied by deficiency symptoms, emaciation, and wasting and atrophic changes The new word for worrying too much about eating healthful foods was coined by Colorado MD Steven Bratman. According to Bratman, a woman named Kate Finn died of the effects of orthorexia. Dieters would do well to recall this advice from the ancients: Observe due measure, moderation is best in all things. Hesiod Moderation, the noblest gift of heaven. Euripides We should pursue and practice moderation.

Expressing Quantity in French - Zero, None - Pas De

Expressing Quantity in French - Zero, None - Pas De Theres a lot to keep in mind when expressing quantities in French. We have  studied  how to express unspecific quantities, du, de la, de l, des, then how to express specific quantities, numbers and expressions of quantity, so now for the last part: when there is nothing, zero, zip, not any! 1 - The Quantity Is None Aha! I bet you didnt think about that one! Well, zero is also a quantity. Which means when you say I dont have money (join the club), you are using a quantity. You could be saying I dont have any money, but the any is often left out in everyday speech.   So, if you wanted to actually say zero, well thats easy, its a number: - jai zà ©ro chat (I have zero cat). But where it gets complicated is when you use a negative. I dont have (any) cat.   In French, wed say something like I dont have none of cat. Please, dont think of it this way, because youd never say that in English, so translating doesnt work. I am just saying it to explain, but its more logical to think of it as pas being a quantity, therefore followed by de/d in French. Je nai pas de chat. (I dont have any cat)Je nai pas de fille. (I dont have a daughter)Je nai pas de lait. (I dont have milk)Je nai pas denfants (I dont have children) And of course, there is a main exception. This rule doesnt apply when your verb is à ªtre (to be). So with à ªtre in the negative, you say the same thing as in the affirmative. Je suis une fille. Je ne suis pas une fille. (I am a girl. I am not a girl). 2 - Adjectives of Quantity Are Not Followed by De/d Aucun/e/s and plusieur/s are adjectives. They dont need an article. Jai plusieurs chats - I have several cats.Je nai aucun ami - I have no friend, I dont have a single friend, I dont have any friend.. 3 - To Recap Some things are easy to quantify: one apple. It’s a whole apple. You usually buy, eat, need one, 2, 3 apples.  But you may decide to be vague, and say â€Å"des pommes† more than one, but I don’t know exactly how many. Now, some things are less easily quantifiable†¦ You don’t buy â€Å"one rice†. You buy either â€Å"one kilo of rice† (a kilo of, an expression of quantity), or â€Å"some rice† (unspecific quantity of an item which is not easily quantifiable). So you need to ask yourself: Am I talking about... A very specific  quantity (a number, or an expression of quantity : une pomme, 5 pommes, un kilo de pommes, une bouteille deau†¦).An unspecified quantity of an item (du vin), or an unspecified quantity of something that you cannot quantify easily (du riz, de la patience)More than one of an item, but a vague plural quantity (des pommes)No item at all (pas de pomme) This is a lot to take in. Read these  lessons over a couple of times and even read it out-loud so you really take the time to understand and process everything.

Case Analysis The International Committee of the Red Cross Essay

Case Analysis The International Committee of the Red Cross - Essay Example The case study demonstrates how the ICRC established a strategy that promoted employees into management and ensure that there is continuity of the values and tradition of the organization’s method of management (Forsythe, 2005). The restructuring provided a new dimension of management in ICRC, which would ensure that employees are encouraged to work for the company. The case study illustrates the importance of continuity in an organization and establishing a system of promotion as a method of motivating employees. Initial Problems in Management Prior to 2007, the International Committee of the Red Cross (ICRC) utilized a poor structure of management, which did not foster any form of development. The problem stemmed from the ideology of employees working in the same group for less than a year. From the on-set, it was evident that the company’s strategy was flawed, because employees were often re-assigned or placed in new teams on regular intervals, which limited their ab ility to develop important skills relevant to the ideologies of the organization (Deresky, 2008). ... The latter can identify a problem of a person, give advice and the person can change their behavior. This illustrates development using a co-worker. However, constantly changing groups will limit the aspect of a person being able to receive tips or advice on how they can change certain elements of how they operate. This was the main problem that demonstrated the poor management strategy implemented by the ICRC prior to 2007. (Merson, 2006) Another problem stemmed from the aspect of bias in the organization. ICRC was originally considered a ‘Swiss Company’, hence their focus related to having Swiss individuals in high positions in the organization, regardless of qualification. This proved to be a hindrance for several employees, who were eager to move on if they found promotion close to impossible. The bias influenced the development of the organization, because on Swiss individuals had a chance of becoming managers in the company. Another problem was ICRC was gender bias . ICRC focused on promoting male individuals to higher positions in the organizations, the Swiss males were the only individuals that would last for a long time in the field before gaining promotion in the firm, and it limited the women’s ability to develop any adequate experience in the field. The main management strategy focused on Swiss males, and it pushed other employees to work short-term for the ICRC. (Forsythe, 2005) The Restructure of Management In 2007, ICRC developed a strategic plan, which was intended to last the following three years. The organization focused on improving the Human Resource Management (HRM) to employ quality managers. ICRC concentrated on three aspects: accountability, multidiscipline, and

Feminist geographies . The intellectual and political significance Essay

Feminist geographies . The intellectual and political significance - Essay Example It was coined by the French philosopher Charles Fourier. It spread to Great Britain and America by the year, 1910 (HAAN, DASKALOVA And LOUTFI, 2006). Feminist Geography or Feminist theory is the expansion of the study of feminism into a wide horizon of issues and experiences that women encounter. It covers the realms of both philosophical and theoretical aspects of female rights and place. It is primarily aimed to fathom the fabric of gender inequality and its causes and effects on human nature and society; it investigates women’s experiences, social roles, interests, and studies and develops theories on feminist politics in fields such as sociology, philosophy, economics, anthropology, education, psychoanalysis, literary, communication. In addition, feminist theory expounds on female welfare, promotion of women’s interests and gender inequality. Research on Feminist theory revolves around two key points: 1, the research should analyze and expound on the state of women in society; 2, the research should be a derivative of the assumption that women are generally considered subordinates to men. However, it abstains from being excessively political and negates research that is conducted to only achieve gender equality. The fields of interest for researches on feminist theory are sexual objectification, patriarchy, art history, oppression, stereotyping, contemporary art and discrimination (KOLMAR And BARTKOWSKI, 2005). Feminist theory in the past has gone through many changes; from being a movement that just aimed at consolidating and establishing women as a universal entity, to being more motivated towards individuality, diversity and social differentiation. Modern-day feminism has assumed the role of promoting the following issues faced by women: equality in property law, voting rights and rights to run for office, equality in contract law, reproductive rights, this includes open access to contraceptives and abortion, physical integrity, equal pay f or women, articulation of for protection of women from domestic violence, sexual assault and sexual harassment. This has led to the advocacy for workplace rights, such as maternity leave. However, feminist theory has also concluded that for female rights and feminism to succeed, men should also be liberated and that men also suffer from gender inequality (HANNAM, 2007). The popularity and rise of feminism has produced different forms of political movements which have branched into a larger part of society, such as conservatism and liberalism, and some interlink feminism with environment. Liberal feminism aims to achieve individuality and equality of women and men through legal and political reforms without morphing the framework of culture and society. Radical feminism aims at extremes; it deems the notion and practice of male dominance on women through capitalist rule as the primary reason behind oppression on women, this leads to the advocacy of total conversion of society and imp lementation of rules that change the total outlook of society according to the manner that women desire. Furthermore, Conservative feminism only aims to achieve the basic human rights for women and stipulates that women should be conservative against men according to the society in which they live. Libertarian feminism believes that people are self-owners and thus entitled to govern themselves according to their wishes, in reference to women, and that

Western Governors University Essay According to The Levine Institute (2013), the term globalization can be defined as â€Å"a process of interaction and integration among the people, companies, and governments of different nations.† Globalization and modernization have been occurring for thousands of years around the world. This can be further explained as the influence that modern nations have on non-developed nations and cultures. The influences that modern nations have can either be related to direct or indirect contact. Both globalization and modernization can have positive and negative impacts on cultural practices. The purpose of this paper is to analyze the effects of globalization on native non-Western cultural practices. Some examples of globalization on native non-Western cultural practices include the influence of cable television in India, the booming commerce in China, and the factor that globalization has played in South Korea’s growth and economic success. While some have had success and felt positive economic effects of globalization, the influence of television in India may have negatively impacted the previously religious and spiritual cultural that existed before the globalization period. This cultural shift in India was influenced partially by the World Trade Organization. The World Trade Organization assisted in lowering import taxes which allowed India to economically benefit by being able to produce products at a much reduced price for the American consumers. The cultural in India significantly changed during this period and while it was previously uncommon to see unrelated women and men living together before the economic shift, it is currently common practice. The economic shift that was directed related to globalization may have also been responsible for unintentionally influencing an increase in violence over the past decade. Another example of globalization takes place in Japan. When McDonald’s restaurant first came to Japan in May 1971, a phenomenon was created by introducing the concept of Western â€Å"fast food† to a foreign country (Chang, 2011). Before the introduction of McDonald’s, Japan cultural had centered on family food preparation and rituals, such as obento. Obento is prepared by Japanese mothers and â€Å"The tradition becomes part of the social education of both parent and child and creates a connection between home and school for a youngster’s earliest forays away from family† (Gordon, 2005). Japanese mothers would spend nearly an hour crafting the elaborate obento for their child to take to school every day. Teachers would judge the obento and ensure that specific rules were followed during the crafting of the meal, such as the food being as handmade as possible, appetizing, and aesthetically appealing (Gordon, 2005). In Japan, obento symbolized the mother’s responsibility to food preparation and a child’s responsibility to education. The introduction of McDonald’s took some time to spread in Japan but cleaver marketing strategies aided in changing the face of fast food. According to Chang (2011), â€Å"McDonald’s marketed as a stylish place to go to with family and friends. They have also included special menus for Japanese customers such as American regional burgers and teriyaki burgers.† McDonald’s also added a variety of unique toys that were specific to the Japanese culture in kid’s happy meals. Since the introduction of fast food, Japan’s obesity rates have risen tremendously. The director of the Drug Discovery Research Center at Kyoto University, Gozoh Tsujimoto, blames Westernized fast food for Japanese obesity rates rising threefold from 1962 to 2002 (Hooper, 2012). Tsujimoto attributes the 20% Japanese obesity rating related to â€Å"Lifestyle factors have become Westernized. Especially, food has become Westernized – and mainly high-calorie and high fat† (Hooper, 2012). McDonald’s now has over 3,300 restaurants in Japan, which is the largest number of stores outside of the United States (Chang, 2011). In addition to obesity and food preparation practices, the introduction of fast food in Japan has also caused a large increase in the consumption of red meat. The older and younger generations in Japan responded differently to the influence of fast food. The older generations continue to eat at home more often, however, the younger generations continue to eat out more and they have shown an increase in health issues, such as diabetes and metabolic syndrome (Hooper, 2012). While some professionals continue to blame the direct influence of Westernization for these unintentional health concerns, globalization is unavoidable and can impact a culture both positively and negatively. Japan has positively benefitted from globalization in ways of technological advances and automobiles but perhaps was negatively affected by the phenomenon of fast food. Globalization is controversial. According to The Levine Institute (2013), â€Å"Proponents of globalization argue that it allows poor countries and their citizens to develop economically and raise their standards of living.† Globalization in India greatly helped the economy but perhaps hurt the values of the cultural. However, opponents of globalization argue â€Å"that the creation of an unfettered international free market has benefited multinational corporations in the Western world at the expense of local enterprises, local cultures, and common people† (The Levine Institute, 2013). Globalization is affected by many variables such as age, family, religion, and technology. Whether it is intentional or unintentional, direct or indirect, planned or not planned, finding the right balance to provide positive effects is difficult. References Chang, S. (2011).

ZigBee Physical IEEE

ZigBee Physical IEEE This report work started with extensive literature study in several area of ZigBee, particular in the physical aspect. This knowledge was then implemented in simulating the physical aspect of the Zigbee working in the range of 2.4 GHz. Various parameter of the physical layer are alter to demonstrate the its effect by using MATLAB(syntax code in M-file and Simulink). Results are analyzed and compared to demonstrate how the actual standard and specification are derived. 2.0 Literature Review Zigbee is known as IEEE 802.15.4 Low-Rate Wireless Personal Area Network (WPAN) standard is part of the IEEE 802 family of digital communication standards. It is designed for low-cost, low-power applications that require relatively low data throughput which is down to an average of less than 1 bps. It is also differentiated from IEEE 802.15.1TM (Bluetooth TM) in several respects; it does not support isochronous voice, as Bluetooth does. Figure 2.0(a) shows the comparison with standard and technologies. 2.1 Applications ZigBee technology is well suited to a wide range of energy management and efficiency, building automation, industrial, medical, home automation applications. Essentially, applications that require interoperability and/or the RF performance characteristics of the IEEE 802.15.4 standard would benefit from a ZigBee solution. Examples include: Demand Response Advanced Metering Infrastructure Automatic Meter Reading Lighting controls HVAC control Heating control Environmental controls Wireless smoke and CO detectors Home security Blind, drapery and shade controls Medical sensing and monitoring Universal Remote Control to a Set-Top Box which includes Home Control Industrial and building automation 2.2 Advantages The most appealing advantages Zigbee has is low power consumption due low duty cycle of end device that only turns on when required, uses only small capacity of battery but long operating time. It is also relatively low cost compare to other wireless network. It offered low message throughput with the size of code ranges from 32kB to 70kB and is only approximately 10% of code size used in Bluetooth technology. Other advantages are listed below: -Large network order. -Few QoS guarantee -Selectable levels of security based on the Advanced Encryption Standard with 128-bit keys (AES-128) s. 2.3 Physical layer IEEE 802.15.4/ZigBee has two available physical layers. In the 2.4-GHz band, it supports a data rate of 250 kbps; there are 16 available channels, centred at 2405 + 5k MHz, where 0 ≠¤ k ≠¤ 15. The other physical layer is a regional one, covering the 868.0 to 868.6 MHz band available in Europe and the 902 to 928 MHz band available in much of the Americas. There is a single channel in the 868 MHz band, centred at 868.3 MHz, with a BPSK data rate of 20 kbps; the standard supports a BPSK data rate of 40 kbps in the 902 to 928 MHz band, with channels centred at 906 + 2k MHz, where 0 ≠¤ k ≠¤ 9.[1] 2.4 Network topologies To meet its wide range of potential applications, IEEE 802.15.4/ZigBee supports star, mesh, and tree networks, the latter two being multihop networks. Multihop Network: A multi-hop communications allows data from one device to be relayed to another device via intermediary devices. By relying on these intermediary devices, the range of a given network can be significantly increased while at the same time limiting the power consumption of each device. [2] Star Network: Star network topologies are commonly referred to as point-to-point and point-to-multipoint networks. This topology can be supported by either ZigBee or 802.15.4. In this network, all devices are limited to â€Å"single-hop† communications. Typical applications for star networks include garage door openers and remote controls. [2] 2.5 DSSS (Direct Sequence Spread Spectrum) IEEE 802.15.4 uses direct sequence spread spectrum (DSSS) for robust data communications. A DSSS spectrum system is spreading baseband by directly multiplying the baseband data with the PN code sequence. At the receiver side code, synchronization is received and the signal is passed through a filter. At the next step, it is multiplied by a local version of the same PN sequence. The received data are then dispread. The signal bandwidth is reduced. An interference signal will be spread when multiplying with the dispread sequence and the power of the interference is reduced when the bandwidth are increased. The part of the interference signal that does not have the same bandwidth as the desired signal is then filter out. In this way the most of the interference power is eliminated. 2.6 Channel Access There are two types of channel access in the IEEE 802.15.4 defined communication system. They are based on whether the devices want to retain their own exclusive time slot for communication or they have to compete with other devices for accessing the channel. The contention based allows the devices to access the channel in distributed way using CSMA CA algorithm. With this method each devices has to scan the air medium for free channel or to compete with other devices for the channel access. With contention free method, the network coordinator decides about the channel access by using Guaranteed Time Slot (GTS) of the channel space. This method is suitable for latency sensitive devices that require short delay time and no competition for channel access. To meet its low average power consumption goals, IEEE 802.15.4/ZigBee is capable of extremely low duty cycles — below 10 ppm [3]. The standard also supports beaconless operation — an asynchronous, asymmetrical mode supporting unslotted CSMA-CA channel access for star networks — that enables devices other than the receiving central node to remain asleep for indefinite periods, thus reducing their average power consumption still further. 2.7 Data processing IEEE 802.15.4 2.4-GHz physical layer uses a 16-ary quasi-orthogonal signalling technique — trading signal bandwidth to recover sensitivity with coding gain. A particular 32-chip, pseudo-random (PN) sequence is used to represent four bits [3].A chip is a symbol from p-n code sequence. There are 16 chips sequence and one is defined in table below: Information is placed on the signal by cyclically rotating or conjugating (inverting chips with odd indices) the PN sequence 8. The PN sequence is rotated in increments of four chips: symbols 0 through 7 represent rotation without conjugation; and symbols 8 through 15 represent the same rotations, but with conjugation. In this way, four bits are placed on each transmitted symbol and, because transmitted symbols are related by simple rotations and conjugations, receiver implementations can be simplified over other orthogonal signalling techniques that employ unrelated PN sequences. Half-sine shaped Offset-Quadrature Phase Shift Keying (O-QPSK) is employed, in which the chips of even index are placed on the I-channel and the chips of odd index are delayed one-half chip period and then placed on the Q-channel. The chip rate on either the I or the Q channel is 1 Mchip/s, so the overall chip rate is 2 Mchip/s. The symbol rate is 62.5 k symbols/s, leading to a data rate of 250 kbps. [4] 3.0 Description of the Simulator In this report, Simulink and syntax code (M-file) in MATLAB are used to generate the scatter plot. For the implementation of overall block system in Simulink model, the equivalent block diagram is as shown above. The Simulink model block consists of random integer generator, modulator and demodulator, noise channel and also error rate calculator. Simulink model effectively represent the complicated syntax code into system model block. The signal is generated by using a Random integer, the Random Integer Generator block generates uniformly distributed random integers in the range [0, M-1]. Then, the signal are modulated by OQPSK, the Offset Quadrature Phase Shift Keying (OQPSK) modulation scheme is used in this assignment. As stated in literature review, Offset Quadrature Phase Shift Keying (OQPSK) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. Addictive White Gaussian Noise is then added to the signal to simulate a practical channel w hich consists noise. After that, the signal is demodulated by using the same scheme-OQPSK. Result are compared with the initial signal (output from the Random Integer) to calculate the BER and SER performance of the scheme. The Discrete-Time Scatter Plot Scope block displays scatter plots of a modulated signal, which are located after AWGN block to reveal the modulation characteristics, such as channel distortions of the signal. For M-file code, the sequence is similar as the above block diagram, the following command are to used to generated the random signal : out = randint(m,n,rg) The code represented above generates an m by n integer matrix of random number. Variable â€Å"rg† represent the range of random number to be generated. The modulating part and demodulating are done by using the below code: y = oqpskmod(x) y = oqpskdemod(x) To add noise to the signal: y = awgn(x,snr,measured) Where x is the input signal and â€Å"snr† is the signal to noise ratio. The scatter plot are plotted by using: scatterplot(y) Besides plotting the scatter plot, the BER versus SNR curve are plotted as it is important to compare different modulating scheme in term of the BER performance. This is done by using syntax code in M-file. The complete code is attached in the appendix. The following is the flow chart to describe the sequence of the code. At the end, three graphs are generated ideal BER characteristic, practical BER characteristic and SER characteristic. 4.0 Result and Discussion . Dots are located at the centre of the boundary lines which is within the box or boundary line. This indicated that proper digital signal is being received. The closer the detected level/phase dots are plotted to the middle of the boundaries, the lesser noise and interference to the digital signal. However this diagram will never be obtain in practical cases. Therefore to simulate a practical real cases, Addictive White Gaussian noise must be considered, Additive Gaussian noise disturb the digitally modulated signal during analog transmission, for instance in the analog channel. Additive superimposed noise normally has a constant power density and a Gaussian amplitude distribution throughout the bandwidth of a channel. If no other error is present at the same time, the points representing the ideal signal status are expanded to form circular â€Å"clouds† as shown below. As figure above shown, scattering of the dots indicates some marginal signal performance degradation but not enough to cause significant digital bit errors because dots are still located inside the boundary. Only dots to the edges of the quadrant or beyond represent significant degradation that results in bit errors during decoding which are shown in figure below generated by using Simulink . In conventional QPSK, change in the input bit from 00 to 11 or 01 to 10 causes a corresponding 180 ° shift in the output phase therefore an advantage of OQPSK is the limited phase shift that must be imparted during modulation. The sudden phase-shifts occur about twice as often as for QPSK (since the signals no longer change together), but they are less severe. In other words, OQPSK has smaller jumps when compared to QPSK. This lowers the dynamical range of fluctuations in the signal which is desirable in engineering communications signals. As mentioned earlier, the simulation is performed to study the performance of the design model. The study is done by observing the bit error rate (BER) with respect to the signal to noise ratio (SNR) The simulation (Figure 4.0(f)) compares the BER versus SNR curve for different modulation scheme used. Four different modulation schemes is taken into comparison, which is the Quadrature Amplitude Modulation (QAM), Quadrature Phase Shift Keying (QPSK), Differential Phase Shift Keying (DPSK) and finally Offset Quadrature Phase Shift Keying (OQPSK) employed by Zigbee operating at 2.4GHz radio band. By comparing different modulation scheme give better insight on which modulation is better and suitable. All modulation schemes are simulated with the value M = 4, where it is effectively represented by n = 2 bits which can be calculated from the following formula below: n = log2 (M) The first graph below shows the theoretical bit error rate versus signal to noise ratio curve. For practical system, white Gaussian noise is added. If comparison is made between theoretical graph and practical graph, it shows that there is not much of the different in term of the shape of the graph. ,it shows that for all the modulating scheme, the higher the SNR the lower the BER (bit error rate).The same principal are apply to the symbol error rate(SER) vs SNR(figure 4.0(g)). For BER vs SNR, comparing the four different modulation schemes from the practical graph plotted, DPSK modulation scheme shows to have the worst bit error rate at any level of SNR, followed by QPSK and QAM having approximately similar bit error rate at any SNR level. The OQPSK tends to have the lowest bit error rate at any SNR level if compared to other modulation scheme, which is desired. The comparison is done by taking one fixed SNR level, for example, considering the SNR level of -2. The bit error rate of OQPSK falls approximately to 10-2, which is the smallest. The QAM and QPSK have bit error rate falls within the range of 110-1 to 510-1, slightly much higher than OQPSK. The DPSK has the highest bit error rate, which is above the range 110-1. 2dB Graph 4.0(h) illustrate symbol error rate (SER) versus signal to noise ratio (SNR) under the same condition for the four modulation scheme. The SER versus SNR curve has similar characteristic over the BER versus SNR curve, with OQPSK being in the best performance, followed by QPSK and QAM and DPSK having the worst performances. Low average power is achieved with a low overall system duty cycle. However, low duty cycle must be achieved with low peak power consumption during active periods because most of the target power sources have limited current sourcing capabilities and low terminal voltage, and it is not desired to implement with complex power conditioning systems for cost and efficiency reasons. At the physical layer, the need for low duty cycle yet low active power consumption implies the need for a high data rate (to finish active periods quickly and return to sleep), but a low symbol rate (because signal processing peak power consumption is more closely tied to the symbol rate than the data rate). Therefore, this implies the need for multilevel signalling (or m-ary signalling, with m > 2), in which multiple information bits are sent per transmitted symbol. However, simple multilevel signalling, such as 4-FSK, results in a loss of sensitivity. As can be seen from figure 4.0(h), OQPSK provides a 2-dB increasein sensitivity over nearest scheme (QAM). For modulating scheme with low sensitivity, there is a need to recover the needed link margin (i.e. range) without resorting to directive antennas, the transmitted power must be increased or the receiver noise figure must be reduced, both of which can increase power consumption significantly. 5.0 Conclusion In conclusion, IEEE 802.15.4 is still a new standard which has the potential to unify methods of data communication for sensors, actuators, appliances, asset tracking devices and so on. It offers the means to build a reliable and affordable network backbone that takes advantage of battery-powered devices communicating at low data rates. In addition the complexity and cost of the IEEE 802.15.4/Zigbee-compliant devices are intended to be low. It can potentially create a whole new ecosystem of interconnected home appliances, light and climate control systems, and security and sensor sub-networks. In this respect, the implementation of the physical layer of the IEEE 802.15.4 standard must be optimized to meet the challenging low-cost and low-power targets. From the context above, various test and evaluation on the BER versus SNR curve and scatter plot for various scheme are done on physical layer of the ZigBee, the result shows that OQPSK is the most suitable modulating scheme which fit the ZigBee (2.4 GHz band) characteristic (low power consumption, high sensitivity, high reliability and low cost ). Thus it coincides with the actual standard for Zigbee. 6.0 References 1. Sensor Technology Handbook, Page 593 Section:  22.
