The market segmentation

Market segmentation is the process of identifying markets and then dividing those markets into groups.   The groups consist of characteristics that are similar and they have similar product needs.   The groups can consist of people or organizations.A market consists of people or organizations that have similar needs of a product, have the ability, willingness and authority to buy products.   There are two types of markets the consumer market and the organizational or business market.   The purpose of the consumer market is to supply goods and services to the customers for their own benefit and not for sale.   The organizational or business markets are markets that are business oriented such as the products in the markets are usually sold thus the businessmen sell them for a profit.The reason behind the dividing the market is to identify groups of customers who have similar tastes and preferences, to understand the customers behavior so that the right kind of goods are deliv ered to them and to ensure that the right marketing strategies are identified so as to ensure that the different preferences chosen to satisfy the needs of the customers If a product can be from a particular company   whose cost of advertising is low thus   it can be   in a position to boost sales of a company   since the cost of maintaining it is low and their returns can increase with time..Successful market segmentation is one that has the following characteristics: segment members that are internally the same and externally different or heterogeneous.The market can be segmented based on whether it is a consumer market or an industry or business market. In the customer market the basis of segmentation is based on variables such as the geographical, demographic, and psychographic and the behavioristic variables. The psychographic segmentation is a segmentation that is used to describe the customers in terms of their activities, opinions, emotions, values, motivations and l ifestyles.These enables the producers of the products to know which product are beneficial to the customers in terms of their preferences and tastes.   The application of this segmentation enables the manufactures to improve on their mode of developing their products, brand positioning, targeting and advertising so that the sales volume of the product can increase and this can result in greater returns for the company.The demographic segmentation involves classifying people who come from the same geographic boundaries and those who possess the same goals for example in a banking industry the introduction of automatic teller machines can enhance efficiency in the business because it can enable the customers to access cash quickly and to enable them complete transactions promptly since the machine is located in a place where customers are many hence the service delivery process is efficient for this customers.Geographical segmentation refers to dividing segments based on their regio n of the world, country size and density of the area. In the rural areas we have products such as the farming equipment and material because they are mostly used there while the urban centers consists of products that have been produced and manufactured and are ready for consumption since the residents there do not have land to cultivate products for consumption for themselves and for their children.The market can be segmented in the industrial market using the following variables: Location, company type and the behavioral characteristics.In case of the location variable the businessmen consider this factor seriously because the distance between where the source of the product is made and the market can be too big such that the cost of transportation can be too high for the businessmen to afford and thus render the market to be unprofitable thus this issue should be addressed so that it can be eliminated in the future.   .In case of company type segment the customers can be classi fied according to the company size, industry, decision-making and the purchase criteria.   The customers can prefer a commodity based on how well the product has been in the market and whether the industry in which it is produced is known because customers tend to accept a product, which has been in the market for a long time. (Steenkamp and Ter Hofstede 2002)The behavioral characteristics in the industrial market are: usage rate means the frequency in which a product is consumed if it is high it means that its demand is high thus it supply is likely to be high for example goods such as the consumable’s such as salt ,sugar there is a likelihood of being demand many times because people cannot stay without them,   buying status that is customers who regularly consume a product   can make the target market to perform effectively because of their consistency in purchasing their products.The procedure of purchasing the product is also determined such as the sealed bids or n egotiated procedure.   In the sealed bid procedures customers purchase a product based on the price tags of the product this type of segmentation is important to consider since it enables the produce to always have adequate stock of the product so as to avoid stock outs.The criteria that are used in identifying a market segment is that it must be identifiable that is a customer must be in a position to recognize the segment that is appropriate for them since customers tend to consume a product on the basis of how they have the product in the market and its quality.   It must be accessible that is the segment must be within the reach of the customers thus the communication and distribution channels must be improved so that the product reaches the customers within the given period of time that the marketers must advertise their products so that customers can be made aware of the existence of the product..The segments must be substantial that is they must be large enough so that th e resources that are used to avail them to the customers are cost effective that is the cost of product should not be too costly that is the cost of product should not be too large as compared to the revenue that is derived from them. The marketing needs must be unique so that they can be in position to capture a wider market so that customer can be able to change to the new brand in the market and thus increase the sales volume.   The segments must be stable so that the cost of maintaining the product is not too high than the returns that are derived from it.Industrial market segmentation is a segmentation that is used in guiding the industrial and business customers in their decision-making strategies.   The goal of these segmentation is to identify the customers in terms of whether they are potential customers so that their behavior can be identified so as to enable the marketers to identify the important issues that affect them directly .The factors that can affect them are: the prices, programs or solutions that can enable the company to increase their returns within a given period of time.( Haas, R.W. and Wotruba, T.R. 1983).Targeting refers to process of identifying segments that need to be addressed.   The companies tend to choose some segments and to downplay other segment because their aim is to look for segments that produce as much returns to the company as possible.   The target market involves people such as the end user companies’ procurement managers, company houses contracting companies and the external sales agents.Target audience involves individuals that influence the purchasing decision but they do not buy the product such individuals involves design engineers, architects, project managers, and the operational managers. The target markets can be identified by looking at customers who have similar needs so that the produces can channel their efforts to products that are beneficial to the customers and they suit their tastes a nd preferences.Positioning involves advertising the product value to customers so as to increase the products sales volume. Positions are described using various variables and using parameters that are essential to a customer.   The customers position a product in relation to the brand or product that is within their reach.   Thus it is important for the marketers to conduct a research about how the customers rate different products and their marketing variables so that they can increase their sales volume. The markers need to improve on their marketing variables so that they can improve on their marketing strategies because the customers can determine the success of the business.   The marketers should set up strategies which are geared to having a portfolio that can ensure that their product compete with.Positioning involves how people perceive a product that is in the market.   The products or services provide a map that enables the marketers to identify which characteris tics can be compared and contrasted to another product that is competing with it so as to put in place mechanisms that will enable them to compete effectively with their rivals.Market segmentation is therefore necessary because it enables markets of different sizes to compete effectively since markets are divided based on their segments thus the small companies can be able to compete with the bigger companies since their scale of production is limited due to their size and the shelves where goods are displayed can not be in a position to accommodate all kinds of goods unlike the big companies whose economies of scale is high due to their size.REFERENCESApproaches†, (1980) Marketing Science Institute, Working Paper #80-105 Cambridge,Mass.Haas, R.W. and Wotruba, T.R.

Goals Statement Essay

When I first sat down to write my educational goals statement, I thought it would be easy. I am an extremely goal oriented person, with my entire life being spent focusing on â€Å"what’s next†. So, how difficult could it be to simply write down those goals? When I began writing, however, I discovered it was going to be a little more difficult than I anticipated. I realized that it may be possible to have too many goals. My list was long and confusing with some goals very specific, and others vague. I thought to myself, how can I produce a smart goals statement out of this? So I re-evaluated my list and discovered that my goals could actually be divided into three predictable categories: immediate goals, short-term goals, and long-term goals. I decided then to choose one from each category to focus on for this report. My immediate goals were fairly general, but all related to my success as a student, so my main goal as student is to get an A in all of my online subjects, and this is a goal that I will go reaching slowly, day by day over the course of this course and in my following online courses. I feel a little intimidated when taking these online courses because my native language is Spanish and having to study in English is an extra challenge for me but I know that with effort and dedication I will get the A that I’m hoping for.

Electronic Monitoring System Implementation Case Study

Electronic Monitoring System Implementation - Case Study Example I have been appointed as the consultant and my responsibility is to carry out a research-oriented study for management Board of an organization, for the implementation of the electronic monitoring system for the better management and handling of the employee’s activities and daily tasks on the job. This report will provide a deep insight into the overall organizational implementation new electronic monitoring system. Companies desire to be persuading their personnel are carrying out a first-class job; on the other hand, employees don't desire their every trip or sneeze to the water-cooler logged. That's the fundamental conflict or clash of office observation (Workplace? 2009). Up-to-date technologies put together it feasible for organizations to view numerous activities of their worker’s occupation, predominantly on computer terminals, telephones in the course of voice mail, electronic as well as when workers are making use of the Internet. This sort of monitoring is practically unregulated. As a result, except business strategy purposely position otherwise, our company can listen, observe as well as read the majority of our place of work communications (Workplace? 2009). From the perspective of workers, electronic monitoring through companies engages considerable isolation distress. Electronic monitoring allows an organization to check what staff is performing on the duty as well as investigation of worker communications, encompassing Internet activity and e-mail, frequently confining as well as evaluation of communications that workers judge privately. Since electronic monitoring as well comprises utilize of computer forensics, a comparatively innovative discipline as well as a significant progression in the wider areas of computer evidence and electronic monitoring (King, 2009). There are numerous business reasons for organizations to electronically monitor employees in the place of work encompassing the judgment of employee’s effectiveness, defending organization’s property from mistreatment, as well as making sure and fulfilment through the place of work  strategies.

In the last, research methodology of the dissertation is elaborated which is based on survey through questionnaire. 1.2 Background of the Dissertation The following dissertation deals with the concept of organizational justice, which is increasingly gaining importance in corporate spectrum. Employees’ perception about level and the nature of justice and fairness in an organization influence their performance, level of job satisfaction and trust towards management. Organizational justice can be defined as perception of employees in relation to fairness in decision-making, interactions, outcomes and procedures in relation to the organizational management (Colquitt, Greenberg and Zapata-Phelan, 2005). These perceptions are so powerful that they can alter one’s attitude for good and ill as numerous organizational conflicts have repeatedly shown that the an organization is as good as its employees. The strength of an organization remains in how well organized is the manageme nt structure and how transparent is the management towards the employees regarding any ongoing, past or upcoming issues within the organization. Along with this, it can influence employees’ performance both negatively and positively and thus can have direct impact on organization’s success. It is also a part of sound managerial practices and its successful application brings fruitful results for the organization.

Knife crime in the uk Essay Example | Topics and Well Written Essays - 1750 words

Knife crime in the uk - Essay Example When one compares the crime statistics of UK with that of the world statistics, it can be seen that the country constitute a meager portion of similar killings but it is considered as a national crisis. Reports state that there was an increase from 12 killings in 2006 to 37 killings nationally in 2007 in which the victim and assassin were under 18, clears the doubts related to the alarming problem of knife crimes, especially among the teenaged. A government Bill which is currently in the House of Lords features Legislature to prohibit the sale of knife or other sharp instrument to those who are under 18. Here, Mick Hume points out: "Total murders in London were down in 2007 for the fifth year in succession, from 222 in 2003 to 160 last year. Within those figures, the numbers of teenagers killed did rise - by 'over 50 per cent' as some reports put it. In hard numbers, however, that was an increase from 17 deaths to 26." (Hume 2008). When the total rate of crimes in London shows a decr easing tendency, the numbers of teenagers killed is at an increasing rate. In older days, holding a knife for self defence was not considered as a serious offence. But now the situation is becoming more and more complicated and laws in countries worldwide limits the rights of citizens. When a teenager commits a crime by using a knife, there are some limitations to the hard laws. The punishment is decided according to the seriousness, circumstance, seriousness of the injury, etc of the person who committed the crime. So, illegal carriage of knife will result in imprisonment up to 2 years. There are Borstal schools and Juvenile homes for the teenagers who had committed the crime. Here, W. J. Forsythe points out that, decision to construct these sorts of schools and houses for the teenage criminals is to transform their character. As Forsythe states, "They had come into being as a result of assumptions that young offenders were contaminated by prolonged contact with older prisoners, that they lost their dread of prison if sent there at an early age for length y periods and that, because of youthful plasticity of personality and susceptibility to environmental influence, they would respond to a regime of training and education." (Forsythe 1990, p. 45). At these schools and homes, the teenagers are provided with training and education for their future life. The punishment is for the crime committed, not against the person. The psychological and mental torture suffered by the person who committed the crime must be considered. Rod Morgan and Malcolm D. Evans observe: "This view implicitly underpins the suggestion that torture is almost universally proscribed and deprecated and is engaged in only by aberrant individuals or regimes, mostly in far-away places: that is, a phenomenon that need not much concern us in Europe." (Morgan and Evans 1998, p. x). By generalizing the problem of torturing the teenaged criminals, the right as a human being is limited. Moreover, violence is considered as an important topic in British law and the punishment i s decided according to the seriousness of the crime committed. According to J. Carter Wood, the study of the history of crime states that extend of crime had risen or declined according to social change: "Violence has become a distinct topic in English historiography through the histories of crime, the

Congestive Heart Failure Case Study Example | Topics and Well Written Essays - 1750 words

Congestive Heart Failure - Case Study Example The patient history demonstrates that he smokes 1.5 packs every day. The patient has been smoking for 35 years. The patient’s smoking is one of the risk factors which predisposed him to his heart condition. Moreover, the patient is an occasional drinker which predisposed him to his heart problem. In addition, lack of proper exercise and failure to adhere to a healthy diet. Psychological stress would also be among the risk factors predisposing the patient to his heart condition. The patient is currently on ECASA, Isosorbide dinitrate, Metoprolol, Nitroglycerin, and Glyburide. The current treatment is aimed at relieving of symptoms of the patient’s heart condition, prevention of worsening of the condition. The current treatment is also aimed at treating the condition of the patient. The drug indications for the patient include ECASA which contains aspirin as an active ingredient. This drug is effective and appropriate for the relief of pain related to heart conditions. Mo reover, ECASA is effective in the prevention of possible inflammation to the heart which would worsen the condition of the patient. The indication for isosorbide dinitrate is appropriate for the management of the patient’s condition because this drug is effective in the prevention of chest pain related to heart conditions especially angina. Nonetheless, isosorbide dinitrate has adverse effects such as lightheadedness, flushing, and headache which must be taken into consideration in the management of the condition.  Ã‚  ... Metoprolol acts through blockage of beta-adrenergic receptors of heart muscles. This illustrates that metoprolol is effective in preventing the complication of the patient’s condition into heart failure as a result of adrenergic stimulation. It is however important to note that drug interaction of metoprolol with digoxin and calcium channel blockers would result in excessive reduction of blood pressure. Therefore counter indications must be provided during the prescription of metoprolol for the patient’s condition. Nitroglycerin is an appropriate vasodilator which is indicated for the treatment of the patient’s congestive heart failure. Glyburide which acts to lower the glucose levels in blood is an appropriate indication for the patient’s heart condition. This is because glyburide acts as an adjunct to exercise and diet. Since the patient is short of breath, exercising would not be viable and hence the appropriateness of glyburide as one of the medication s for the management of his heart problem. The dosages of these medications as provided in the indication are appropriate for the adult patient. Nonetheless the condition of the patient would influence possible adjustments to the treatment. In order to ensure that the patient adheres to the medication, the health care provider must ensure compliance by encouraging the patient to take the drugs. This would be achieved by explaining the importance of adhering to the dosages and the possible side effects that are related to the drug. When the patient is presented with the possible side effects, he would be enabled to selective alternative drugs for the management of the

Integration of the internal data with the external variables is another feature function of E.I.S. Creating a budget that is in line with the needs of the organization is also made possible through this utility feature system. Owing to their excellent output, their increased productivity and reduced hassle, the larger enterprises and front runner business trend setters have adopted these systems into their networks. Data mining is a modern trend that has emerged with the evolution of the information technology based support systems. As the name would imply, it is the investigation and assessment of the different variables and different data sheets and facts through a certain critical viewing and perspective. The two concepts are equally intertwined, while data mining is related to the dissected and detailed investigation and assessment of the overall facts and data at hand, the data warehouse in contrast serves as a repository of information and overall monitoring level tool and software support system. Number of techniques and strategies can be adopted with regard to the data mining process and utilization of the software. Two of the most commonly used techniques include clustering and classification techniques. Through the technique of clustering different set of variables may be brought together for a cumulative assessment of key variables. The cluster technique allows targeting and segregating two set of variables and responders in a data set collected from a survey or any other observational study undertaken. Pre determination

EU Competition Law Essay Example | Topics and Well Written Essays - 4250 words

EU Competition Law - Essay Example These cartels have negative impacts and it has been made illegal under EU rules on competition. The EU Courts to such cartel firms can impose heavy fines.  The pursuit of EU competition laws has been huge but there has been doubting as to the exact goals of their laws. Comparison of laws in the decentralized EU competition enforcement with other national laws on competition reveals parallel pursuits in its application. This essay analyses an overview of competition laws by the EU and its members and looks into detail the enforcement system of the EU competition law and any inconsistencies noted in the application of the rules. It also analyzes duties of such authorities when matters of enforcement of Section 101 and 102 of the TFEU are to be affected. According to Ezrachi, 1competition law is very important to the European community and its organs. Its core platform of EU is to facilitate the industry. The industry due to its competitive nature provides advantages for people involv ed and ensures proper functioning of its market and the European industry. Therefore, the EU nature must protect effective protection of such competition.The EU fosters obligatory requirement for member states to embrace converged forms of substantive procedures for enforcement of such laws. This has always posed a major challenge in the realization of unified competition laws. National laws on competition are radical towards the creation of right policies on competition regulations. These laws have been regarded as relevant for publicity of the Commission in creating effective policies. Power 2 explains that total reliance on the commission for effective enforcement of national procedures and its institutions has created the absence of clarity in the goals of its laws.EU competition law drafters lacked a clear focus on its goals since they failed to think of the best enforcement regime. These laws lack procedures for uniform practices to all members states.

Limitations and Requirements of ANOVA Essay Example | Topics and Well Written Essays - 500 words

Limitations and Requirements of ANOVA - Essay Example The samples’ variances should not be different though some departures can be accommodated. All individuals used in the samples must be selected randomly from the population. All individuals of the samples must have equal probability for being selected. The sizes of the sample should be equal but there is an allowance of some differences. One of the limitations of ANOVA is that, when a significant data difference cannot be found, the samples cannot be said to be the same. It only indicates differences between groups and not groups which are different. Normality assumes that the errors which are random within each group of treatment, the groups’ mean deviations, have a normal probability distribution. For normal data but variances which are heterogeneous, ANOVA is good for balanced designs but not for designs which are highly unbalanced. In normal data setting, heterogeneous variances and designs which are unbalanced, Welch’s ANOVA might be used for the accommodation of unequal variances. With variances which are homogenous but data which is non-normal, ANOVA is good for designs which are balanced with large samples. It is not good for unbalanced designs with small samples. In non-normal data setting, variances which are homogenous and a small sample or unbalanced design, a non-parametric procedure is preferred. If the distribution of data is not normal and heterogeneity of variances exist, there might be transformation necessity. The importance of a design which is balanced and existence of a large sample must be pu t into consideration. A common standard deviation is shared by all normal distributions. The different t-test options can be used around the equal variances assumptions or unequal variances assumption. The f-test, apart from being used to for t-tests, it can also be used to compare variations in two data sets in the CJ data. The test makes use of a calculated F stat

British Airways Marketing Report Essay Example for Free

British Airways Marketing Report Essay Current share price is 225 with a range of between 224 and 289. Marketing is ‘the management process responsible for identifying, anticipating and satisfying customer requirements profitably. ’ BA used to operate in an oligopoly market however throughout the last century this has changed. Previously it was only large national companies that had enough money to provide flights however nowadays the market operates in perfect competition with high barriers to entry. BA can use marketing to promote their product, drive market share, anticipate customer requirements, satisfy customer needs and ultimately make a profit. The Marketing Mix The marketing mix is a combination of 4 P’s (product, price, place and promotion) that should be used in conjunction with each other to ensure a competitive edge over other companies. ‘The marketing mix is designed to produce mutually satisfying exchanges with a target market’. Product BA’s product in essence relates to the flights offered. However, the product can be drilled down into specific areas ranging from the airport lounges around the world, the ‘extras’ that you can buy on board such as model BA aeroplanes or even package holidays. Each of these has been specifically tailored to meet customer expectations (which are highlighted in the section of the report titled ‘target market’). This part of the marketing mix focuses on how BA’s products are managed and in the Guardian case study article titled ‘BA, Iberia and American Airlines tie-up heralds new era of transatlantic travel’ dated 06/10/2010 it shows how BA have made an executive decision to link their websites with other companies to have the possibility to offer a higher number of routes (products) to their potential customers. Price Price is simply ‘the amount of money customers must pay to obtain a product’. BA’s price is generally higher than their competitors although this is because they believe they are offering higher quality. However, in recent times BA appear to be losing the price war against low cost budget competitors such as Ryanair and Easyjet. Following this, BA have undergone marketing strategies to reduce their price and carry out ‘sale discounted’ periods. BA demand immediate payment for their products, do not give credit terms or allowances. Promotion In the early days when BA was a nationalised company and the market was an oligopoly, they didn’t have to promote as much, as competition was minimal. However, with the growth of new players in the market BA have resulted to advertising in the following areas: tube stations (especially the Jubilee Line going towards Canary Wharf to target higher earners), newspapers (such as the Financial Times and Sunday broadsheets), airports (mainly in Heathrow and Gatwick – their primary hubs) and adverts between TV programmes, starting from September 2009 – such as the News, Politics programmes and factual documentaries. BA also use personal advertising techniques with their advert: ‘Come together it’s Christmas’. This uses emotional targeting to encourage people to buy their product to visit loved ones during this period. See Appendix 2. Place Currently BA do not operate from London Stanstead however a marketing decision could be taken to include this to their portfolio. This would give them a higher percentage of UK airport utilisation however a cost benefit analysis could prove this move to be not so advantageous. BA have recently ‘taken on’ Easyjet and are now offering a Gatwick-Marrakech route at discount prices. This gives customers higher choice and allows BA to remain competitive and attempt at satisfying the needs of those who want to pay less. Once BA have exhausted the 4 P’s, a S. W. O. T. Analysis will be completed to determine and examine internal strengths and weaknesses and, external opportunities and threats. S. W. O. T. Analysis Strengths The case study website article on ‘This is Money’ dated 24/01/2011 undoubtedly highlights one of the major strengths carrying BA at present. The merger between BA and Iberia has strengthened its financial position and is a step closer to ‘creating a multinational multi-brand airlines group’. BA take pride in their strong brand, high quality service and offer prestigious first class airport lounges to ensure that their customers are taken care of to the standard they expect for the prices they are paying. This is what has allowed BA to charge higher fares and gives them the image that higher class passengers are willing to pay for. By linking themselves to fellow competitors (American Airlines) and strengthening their position by joining the One World syndicate, BA have encouraged higher revenues from this tactical decision. Following the strong decline throughout the global recession, BA’s strength is ‘bouncing back’ according to the BBC News Article ‘British Airways in first profit for two years’. Although the rise in incomes and ultimately rise in profits was linked to higher cargo fares, BA were able to successfully cut costs and meet their carbon emissions targets also. Weaknesses Despite the above, BA has been renowned for strong continual losses as highlighted in the other BBC News Article ‘British Airways reports ? 164m loss’. The losses were mainly caused by the volcanic ash cloud and staff strikes both resulting in the cancellation of thousands of flights. It’s reported that just ’15 days strikes had cost the airline ? 142m’. The strikes had also had a negative impact on their declining reputation making some people not wanting to fly with them anymore. BA’s reputation was also hit when they were sued ? 10K by competitor Virgin for accessing their private files and consequently trying to poach business. If this wasn’t bad enough, in 2009 BA were fined a massive ? 110m for price fixing – known as a ‘cartel’ and this is illegal. Although passengers accept that flight travel can be dangerous, BA adds to its weakness with its own incidents. These range from a mid-air collision in 1 976, a pilot being sucked out of the aircraft when a windscreen exploded and in 2008 a BA plane at Heathrow missed the runway and crash-landed. More recently, BA has been investigating prices of flights to some destinations that were being charged at 10 times the normal price owing to a ‘system error’ online. This is going to make people think twice when booking with the company. Opportunities While the above 2 sections focus internally, opportunities and threats highlight those factors that can influence BA externally. The lifting of the recession in recent months has allowed passengers to review their spending habits and hopefully create higher disposable income in households and allow the ‘loosening of the belt’ for those corporate company credit cards. BA need to carefully position their marketing strategies at the right time in order to capture these people with that bit of extra money to spend and the report will focus on this issue in the following few pages. BA sold its Gatwick hub airport for ? 1. 5bn, although this was reportedly at a loss (as BA originally paid ? 10. 1bn for it 3 years prior), it gave BA the opportunity to invest its interests elsewhere and concentrate on a smaller number of airports. BA also sold its interest in the London Eye – now sponsored by EDF, to focus on other projects. Threats BA has been hit by threats in recent years ranging from terrorism, bad weather, volcanoes and more recently the devastating earthquake and tsunami in Japan and the civil unrest in Libya. Numerous flights have been cancelled to the Libyan capital Tripoli costing BA millions of pounds. Following this, BA has been forced to cancel their entire summer 2011 season of flight programmes. The events in Japan have also affected BA’s programmes with flights to Tokyo disrupted. The case studies provided highlight how BA ‘went into meltdown’ following the heavy snow suffered in the UK during December 2010. The conditions caused hundreds of flights to be cancelled for both cargo and passengers and the title of the article ‘British Airways says bad weather could cost it ? 50m’ sums up the situation perfectly. The terrorist events in the USA in 2001 still continue to make passengers nervous of flying, especially Trans-Atlantic and this is always going to be a sensitive subject that BA would find hard to market against. By doing so, they would not want to seem like they are publicising terrorism but at the same time have concentrated their marketing strategies on the highest standard of comfort and ‘relaxability’. A final threat is shown in an article by the Telegraph where BA is ‘attacked’ by a social media Facebook campaign where Gatwick workers have criticised BA’s Terminal 5 at Heathrow calling it ‘shambolic’ and the page was even designed with videos showing the CEO of BA wrestling with baggage and trolleys. This damages BA’s reputation and makes a mockery of their brand. All of the factors mentioned above in the marketing mix and S. W. O. T. Analysis are important for BA to consider however if the company does not have a target market to aim their products at, the company would not be able to survive. British Airways Target Market and Positioning Strategy In order to ensure BA’s products are directed at the correct audience to maximise revenues and profits, careful market research needs to be invested in to find a target market. ‘The basis of target marketing is market segmentation’; which splits the market into groups of potential customers that have the same characteristics. From the 3 marketing strategies, it’s believed that BA use a ‘differentiated strategy’ as they focus on several specific areas of the market to target. The characteristics below offer ome possibilities that link all of BA’s customers together. Watch the News on television Celebrities Speak a 2nd language Middle/Upper Class Holiday in non-European destinations Read non-fiction In full time employment or retired Have higher disposable incomes By segmenting the customer base to determine a ‘target market’ BA split the market depending on the following variables: * Demographic – age, gender * Geographic – where the target is based * Geo-demographic – size of households, number of cars etc.. depending on location * Psychographic – lifestyle, attitudes Behavioural – the relationship between the target market and the product As the points show in the circle above, BA focus their marketing strategies on those that have higher income and appear in the middle/upper classes of the population, this is evident from the prices of their products and the quality of the service offered. Both genders are targeted equally with the age range (generally) being between 35 to 65. The BA advertising strategies are positioned to target those situations that their customers can relate to and dream about – i. . luxury holidays, comfortable flights and a reliable service. This concentrates on the behavioural variable. Geographically, as BA is a British company, the target market is centralised in the UK however following partnerships with fellow companies such as American Airlines for example, a wider global base is reached. BA have positioned their product away from their low cost budget competitors acknowledging that they offer a more luxurious alternative to cheap travel. Their positioning strategy can lso be seen in the ‘product class membership’ which again, separates BA’s service away from the Easyjets and Ryanairs. By doing this, BA have created their own competitive advantage and have taken an alternative route to satisfy other customers needs that are not centered around saving money. Marketing Recommendations In order for BA to evaluate how successful their target market strategies and their positioning tactics are, the report recommends that the company should see how many levels of ‘Maslow’s Hierarchy of Needs’ are being satisfied from a purchase of a BA flight. This can be seen in Appendix 3. Psychological needs: SATISIFIED: shelter from the cold, provision of food and oxygen * Safety needs: SATISIFIED: provision of a safe environment and reassuring customers * Belongingness and love needs: N/A * Esteem needs: N/A * Self-actualization needs: Possibly relevant to those who are over-coming their fear of flying. Secondly, BA could conduct marketing research to determine ‘why’ customers buy their products in the first place. This could be conducted as a quick questionnaire either in-flight when the customers are all in one place at the same time or as a mandatory set of questions when booking flights. This will help BA to see what criteria are satisfied during the stage of the ‘buyer decision process’. There are 3 possibilities however the report recommends that BA would come across the most popular varible below: * Routine Response Behaviour: Customers who are frequent flyers, possibly members of the Executive Club, they are aware of the low cost competition however have a loyalty towards BA and favour their service. Appendix 4 shows where the report deems BA’s product to currently be in the market. By carrying out the market research above and with the new strong group behind the company, the brand could move backwards in the graph and back and return to the growth stage. This can also be said of Appendix 5, by moving BA from a question mark in the Boston Matrix and positioning it in the ‘star’ category. The report recommends BA to further extend their marketing strategy to concentrate on ‘holidays’ and not just flights. This links closely with an interview carried out by ‘Marketing Week’ and BA’s Head of Marketing, Richard Tams. ‘We are devoting more and more of our reativity in any given campaign to talking about holidays’. BA should extend this further and working with tourist boards of exotic countries to promote cheaper package holidays with the support of the Government in those ‘further to reach’ luxurious locations. Tams states ‘we are looking to move BA. com to much more into the space of a t ravel website rather than a flights website’. The report strongly agrees with this marketing strategy and would fully support BA’s proposals. This widens their product mix and allows a larger more diverse target market to be captured. Conclusion The report has analysed the company British Airways firstly concentrating on the product mix and a S. W. O. T analysis. The report has described the company’s target audience and commented on the current positioning strategy of British Airways. The report has concluded with marketing recommendations that could be put in place to ensure the long time success of the company. Future events that British Airways will have to be aware of include the UK Government adjusting passenger air tax and carbon emission regulations. 2,682 words. Bibliography All referenced throughout.

Moliere’s Portrayal of Religion and Religiosity Essay Example for Free

Moliere’s Portrayal of Religion and Religiosity Essay Moliere’s Tartuffe is about a man named Tartuffe who is a beggar and holy man that was recently taken in by a Christian man named, Orgon. Tartuffe has Orgon fooled, but the entire rest of Orgon’s family sees Tartuffe as a hypocritical, self-righteous con artist. Orgon becomes obsessed with Tartuffe and would rather talk and hear about him than his own sick wife. Even though Moliere rewrote this play twice, there are many reasons that the church might still be concerned about the hypocrisy that he used toward Christianity in this play. In 1666 Tartuffe was banned, a play many found offensive because of its assault on church hypocrisy. Many people of the church could still be concerned, due to Moliere’s portrayal of Christianity and how it is almost mocked in this play. Allot of the comedy Moliere portrays is intense focus on Orgon as example of a certain kind of traditional Christian. He isn’t the ‘only’ type of Christian in this play, but the way he is portrayed is almost in a hypocritical manner. Orgon is so eager to believe Tartuffe, mainly due to the fact that Tartuffe is professing to be another type of Christian. Moliere regards the type of Christian that Tartuffe is as insane. The way mankind is portrayed on behalf of Orgon is almost as depraved as a result of Original Sin, so therefore Orgon has to be subjected, for his own good, to somewhat of a dictatorial control by divinely appointed authorities, or the King. Moliere portrays Orgon as a good Christian man, who is taken advantage of and ultimately almost loses everything because he is willing to take Tartuffe in and treat him as if he were family. The reason the church should be concerned here is the fact that Moliere portrays the way Tartuffe is insane and manipulates the good Christian man. He shows Orgon, the good Christian man as blind to all the wrong, and coming out as essentially the â€Å"loser† and the insane Christian and manipulator, Tartuffe, comes out with all of Orgon’s belongings. After reading Moliere’s Tartuffe I now can see how the church would be heavily concerned with how Moliere portrays Christianity as ‘the nice guy finishes last’ with relation to Orgon and Christianity. The church could also see the hypocrisy by the portrayal of Tartuffe as a â€Å"religious con man† or â€Å"religious fraud. †

An Election Algorithm In Distributed Systems Information Technology Essay

An Election Algorithm In Distributed Systems Information Technology Essay In our increasingly globalised, distributed computer systems have been changed several aspect of our life, especially parallel computing; these days commercial application provide the strength of the development of faster computer, which allow a large amount data in sophisticated way, for instances, economic and financial modelling, database, multimedia technology, and oil exploration. Parallel computing has the ability to solve larger problems, provide the attribute of concurrency, save time and money. Distributed systems architecture leads to a wider use of parallelism as future of computing sector; this evolution made possible to run software on concurrent process on multiple processors. One of the main issues in designing concurrent software is election algorithm. The issue of election algorithm is the very question the current paper seeks to answer. The importance of this issue leads to effectiveness enhancements by develop and design algorithm use a new technique. Therefore, the aims of this dissertation are design and develop this technique, also discuss the benefits of parallel computing. Rationale I have been used the computer and the internet for several of years, my concentration is networks with emphasis in distributed systems. Recently, the internet is vastly interconnected a variety number of computer networks in many different institutions, which make a huge motivation to be professional user; therefore, my MSc course at Oxford Brookes University is really brilliant opportunity for achieving this goal with deep information path for further research in software engineering and networks. In particularly distributed systems are one of the significantly growing on demand in this sector, as they used to accelerate the computational speed of the problem solving. Thus, one of the most fundamental problems in distributed systems is the leader failure, furthermore, it is spectacular to improve and enhance my C language programming. With all these changes in the area of computer industry, my goal to helps and assists for use the election algorithm in distributed systems with a new technique and software for solving the coordinator failure. During study of distributed systems with connecting of parallel computing, this was bring a new interested challenge to go more further in development and contribute to gain wide rang of knowledge, all of these will have prepared me for a future career in computer software engineering and broadened my perspective and enriched my life beyond my career aspiration. Preliminary Research (maybe) Objectives The objectives of this dissertation is to research and develop the theme of an election in distributed systems which allow a group of processes to elect one process to act as a coordinator when a failure happen. However, as well as to achieve this goal PVM (Parallel Virtual Machine) and improve the understanding of this environment as it will used as an environment message passing for this project, this facility provides send and receive data message between processes and support concurrent programming, moreover it is easy and simple to spawn a set of processes. One of the most significant advantages of PVM is provide unified framework within parallel programs like cluster, where is possible for a programmer to divide a block of data into tasks that can run concurrently by send and receive data to all processes. This paper will focus on how to produce an election algorithm use above idea. This environment will be written in C language, and there will be a main program (Master), in which the user can initialise and make the declaration for the main attribute of executed program; there are varieties of functions to send and receive all data types during the communication between programs. The second program called (Slave), this program will carryout the operation after receive the data from master program, then packet the result and send it back. Finally, a part from the objectives will be self skills specifically improve project planning, programming as well as project writing skills. Methods The research methods which used to achieve these objectives will be as the following: Research the Oxford Brookes library for books and documentation for the distributed systems and specially an election and agreement, the library has a lot of sources, the book Distributed Systems: Principle and Paradigms [7] has cover important information to achieve the goal of this project; also the book Distributed Systems: Concept and Design [1] the was a brilliant theory to cover the distributed systems. Another book was giving a complete list of function, examples, and explanation to be familiar with virtual environment [2]. On the other hand, research the Internet, which has a lot of useful materials and describing an election algorithm [3]. Study and evaluate some kinds of algorithms those help and develop the topology idea of the project to achieve my goal. Produce a solution design to meet the requirement of the problem, as well as developed which needed for every task and discussed the findings with my supervisor. Moreover, PVM message passing communication design which gives a right direct path for problem solving. Implement every task as a proposed design use PVM library written in C language. System run and testing will be done on Cluster of school of technology. Make a review and keep an arranging to complete writing of the final report. Testing (may) Resources This dissertation will be achieved by using a variety of resources of software and hardware, also some of information and documents sources that cover all the area of the research. Software The environment of code will be writing in C language, that it support concurrent computer and UNIX, as well as it is simple language to understand. Moreover, it is also support the software PVM (Parallel Virtual Machine). PVM is mainly designed for using by concurrent and heterogeneous environment; it is possible for providing a virtual view. There are many of useful websites like (http://www.netlib.org/pvm3/). Hardware The Cluster of Brookes School of Technology will be needed to implement the project, and all test and run steps will do on it. The cluster consists of 6 nodes with 1 main node ssh 161.73.146.51 connected as processors and run PVM which installed in every node. Information Sources and Experts Advice There are several of documentation belongs to PVM which can be found in the book of A Users Guide and Tutorial for Networked Parallel Computing as mentioned earlier, and websites [4]. Further more, the lectures of modules software technologies that have a good reference of covering the topic of distributed systems in general. Besides all of this my supervisor/tutor Chris Cox who gives useful advice and information as he is specialise in distributed systems programming.

On the theme of distributed systems that enable the computers to coordinate their activities and share hardware, software, and data. The strategies characteristics of the systems which include shared state, multiple computers, and a processor that suited to a particular function to make the improvement for performance and utilization. As well as the concurrent computing have the availability of fault interconnections give the predominance over all the others. All of these offer several advantages: The cost of this computing can be low; each individual task assigned to appropriate architecture that lead to optimized performance. Network computing can be offer a computer task partitioning along of services functions. Another advantage, the computing networks ha ve the capability to execute subtasks of a computation on tolerance. Consequently, one of the major problems that distributed systems face is the failure; this problem can be solved by election algorithm for the agreement to only one node that distinguished and all other nodes aware of it. Thus this paper describes the design and producing an algorithm to achieve communication of parallel programming in virtual environment. The Need of Election in Distributed System Election process is a program distributed over all nodes. When the leader has failed and discovered by one or more nodes, then election starts. The leader election algorithms are used in many topologies. For example, in token ring and when the node that has token fails, a new node should be selected from the system to have the token. The leader election is also used to sole single point failure in client-server that is when the systems need to transfer the leadership to another station and the fail occurs. Many researches have studied the subject of leader election algorithms. The researches presented different techniques and strategies to deal with the election algorithm. The objective of this dissertation is to research the election algorithm in distributed systems and design and develop an election algorithm in distributed systems to choose and agreed with biggest identifier to be coordinator. The software systems PVM used as a library of design and development. Structure of this Documents This dissertation has structured and separated into three parts. The first part describes and discusses the research topic theory of the election algorithm in distributed systems, as provides some applications with description to show and investigate their use in the subject of election algorithm. The second part describes the methodology that adapted to accomplish this dissertation, as well as outline design of the core algorithm and development description which shows the dissertation deliverables. The final part outlines the conclusion with achievement of this project. Chapter 2 Research This section shows the research and development of the related investigation; and moreover, the works that have been done relating election algorithm. It covers the theory of distributed systems and the failure problems; this part was particularly important in the progress of understanding an election and the agreement in distributed systems; and gives a clear idea for design the core algorithm. The need for software technologies module lectures, specially distributed systems was deceive; there were brief description for some material and examples of programming code those were good point to start from for this dissertation. Election Algorithm Theory (in Distributed Systems As more and more, distributed systems have been rapidly changed the field of computer science. Distributed systems are application that executes a collection of autonomous network computers to coordinate and communicate their action. However, the major goal of distributed systems including the ability to connect remote users with remote resources in open scalable way; in other words give an easy way and simple way for the users and application to access remote resources, and sharing the facilities included by efficient/controlled way. Furthermore, the brilliant benefits of sharing resources are vary; the obvious one is economic, that is to say reduce the expenditure for institutions, such as Universities, and also the collaboration will be easier to connect users and resources. This characteristic is a direct as a result of having independent computer [7]. Description An election algorithm: Is an algorithm for solving the coordinator election problem which is choosing a unique process from among a group of processes on different processors to act as central coordinator in distributed system, that is to say a group of processes on different machines need to make agreement to choose a coordinator[7]. However, there is no way to choose/select one process, if all processes are exactly the same and there are no distinguishing characteristics. Accordingly, there requirement is for the choice of elected process to be unique; hence election algorithm attempt to locate process with highest process number and designate it as coordinator [7]. When a failure occurs, which means one or more node fails, or during a communication channel fails the subsystem that enables the nodes/processes to communicate; there is necessity for the nodes to start coordination agreement to elect node for new situation, therefore live nodes can continue working to fulfil their task [3]. Distributed systems have to be adaptable to failures at least by two strategies. The first strategy is a capability for operating continuously and correctly by have software when failures occur (using an algorithm). The other strategy is to take a period of time out to reorganize the system by temporarily halt operation (reorganization by coordinator) [3]. The election algorithms vary, for example: Wired system which are for instances. Bully Algorithm (the biggest guy in town wins) Ring Algorithm Wireless system Very large-scale system Bully Algorithm It is an election algorithm, in the paper of Election in a Distributed Computing Systems by Garcia-Molina [9]; this algorithm can handle process crashes and the presumptions are all processes have got unique identity, all other processes in the network are known by every process and the system is synchronous, that is, there is a maximal time limit T within a request and if the requested process P is alive the request will be answered. However, the algorithm defined as, when there is no responding to the requests from the coordinator, there will an initiating for an election. Therefore: The process P send an election-message to all processors with higher numbers than itself, then P waits for answer-message. The process P will itself elected (P win the election), if the answer-messages are not arrive with in the time T, after that sends a coordinator message to all processors a lower number. Process P will wait a further time period T a coordinator message, if there is one or more answer-message A process P receives an election message and returns the answer-message, then start the algorithm from the beginning if there is nothing have been done before. A process P receives the coordinator message register the senders number and considers it elected. The algorithm will be started , when faulty process restarts; if the process which was previously down comes back up, it holds an election and if happens to be the highest numbered process currently running, this will win the election and take over the job of coordinator. As a result of that the biggest process in all processes always wins; therefore the name is bully algorithm. Here an example of the election of coordinator P2 after the failure of P4 [3]. Election Coordinator Stage 1 Election P1 P4 P3 P2 Answer Election Coordinator Election P1 Stage 2 Election P4 Election P3 P2 Answer Stage 4 Stage 3 coordinator Time out P1 P2 P3 P4 P2 P1 P3 P4 Figure (Bully Algorithm) In this operation, four processes are shown when process P1 detect the failure of the coordinator P4, therefore it is announces an election in the stage 1; during the receiving an election-message from P1, processes P2 and P3 send answer-message to P1 and start their own elect-ion, then in the stage 2, P3 sends an answer-message to P2, for P3 has no answer-message received from P4 which is failed process. Consequently, it decides that it is the coordinator; moreover, in stage 3 P3 fails too before it can send out the coordinator-message. When the timeout period expires for P1, it deduces the absence of the coordinator-message and begins another election; eventually P2 is elected coordinator. Ring Algorithm An election which is suitable for a collection of processes based on the use of a ring; in the book Distributed Systems Concepts and design [1] chapter12 section 12.3 provides a good reference and explanation of the subject of coordination and agreement. However, the messages are sent clockwise around the ring, any process can begin an election initially, every process is marked as nonparticipant in an election, it proceeds by making itself as a participant, so when any process notices that the coordinator is not functioning, it builds an election-message placing its identifier in an election message and sending it to its clockwise neighbour, when an election-message is received by a process, it compare the identifier in the message with its own, the message will be forwarded if the arrived identifier is greater than a received process; whereas, if the arrived identifier is smaller and the receiver is not a participant, then it substitutes its own identifier in the message and forwards it, but if it is already a participant, it does not forward the message. In addition, if the received identifier is that of the receiver itself, thus this identifier must be the greatest, and it becomes the coordinator. Accordingly, the coordinator makes itself as a non-participant once more and sends an elected message to its neighbours announcing its election and enclosing its identity. As well as, if the neighbour process which is received the election message is down, the sender will skip over the neighbour and goes to the next member along the ring, or the one after that until a running process is located. P1 Adds 3 (2 ,3) P1 Coordinator P2 P4 P2 P4 P2 Elected P3 Elect P3 message (2,3) P3 Elect-P2 message (2) P3 Elect-P3 message (2,3) Stage 2 Stage 1 Coordinator = P3 Sends elected P3 (2,3) P1 P4 P2 Elected P3 message P3 receives the message P3 Stage 3 Figure (Ring Algorithm) Supposing P2 detects that coordinator P4 is not responding, thus P2 sets active-list to ( ) and sends elect-P2 message to P3, after P2 sets active-list to (2). However, P3 receives elect-P2 which is the first message has been seen, so P3 sets its active-list to(2,3); then P3 sends elect-P3 towards P4 and sends elect-P2 also respectively, the message will pass P4 and P1 due to their crash and reach P2, the process P2 adds 3 to active-list (2,3), then P2 forward elect-P3 to P3 and receives the elect-P2 message which leads to choose P3 from P2 as the highest processes in its-list (2,3) and sends an elected P3 message, finally P3 receives the elected-P3 and P3 choose P3 as the highest process in its-list. This is an example of process which consists of four processes and the assumption is P1 and P4 are crashed. Distributed Database systems Distributed database technology required to merging of two significant concepts, the integration via the element of database and distribution through the element of networking. Therefore, distributed database management system (DDBMS) provides the powerful tools for managing an integrated collection of shared data, and supply total solution to information processing problems within large organization. Furthermore, the reliability of the data communication facility will be takes into its possibility. However, distributed database require one process to be a unique as coordinator to perform some activities. The [5] provides a reference for using election to choose the coordinator as continuing for duty is required when the coordinator process fails. The election algorithm [6] of TEMPO that running on Berkeley gives another use of choosing a unique process to be coordinator. TEMPO is a distributed system program that adapted on master and slave techniques running on individual process. The reliable communication services for LAN which TEMPO works in and to be sure about its continuity, an election is necessary to elect a new master and should have the ability to perform: withstand the failure of process when the election begin, deal with network partitions, and collect information about the topology of the system by allowing a time daemon. Chapter 3 Method Introduction This chapter describes the design and implementation of the election algorithm. The main point of the design is the aspect which will be used and adapted in order to finish this project; therefore various assumptions and decisions are made to develop main algorithm. In the dissertation proposal report there was assumption idea about the algorithms to be used, but when some design concepts have reviewed and researched the algorithm that based on Bully Algorithm was adapted. All following section covers technical and practical explanation, as well as the process of the design which are made. Finally, testing process to shows the algorithm performance Design Stage The Problem Specification Design After finishing the necessary requirement and research, there were many possible idea gathered in order to produce the design, formulate a clear manner of main election algorithm, and how to achieve the efficient solution to the problem. The design of the communication must take into account the topology of the network, which will be (cluster); the algorithms presented here assume a fully connected topology. Furthermore, the assumption that communications are error free is an abstraction and the assumption of finite but arbitrary transit times for messages is consistent; the algorithm do not to be sensitive to change in the relative speeds of the channel and processors at the nodes, so the correctness will never depend on absolute times. For each node there will be a unique identification number, the message passing model is consistent with that provided with PVM (Parallel Virtual Machine). There are two statements for communication: Sending and receiving messages Send (MessageType, Destination [, Parameters]) Receive (MessageType [, Parameters]) For example below node 1 sends a message of type request to node 2 with two integer parameters values 13 and 27. integer k= 13 send (request, 2, k, 27) integer m, n receive (request, m, n) node 1 node 2 (Node communication) When the message is received at node 2, these values are transferred to the variable m and n declared at the node. The core Algorithm Architecture Discuss the algorithm process Send side: Receive side: The design of the algorithm will using fully connected, and it is extremely efficient in that any node can send a message directly to any other nodes, but it is extremely expensive because it needs more communication channel. This design allows process to crush during the election where there are three types of messages; an election message is sent to announce an election; an answer message is sent in response to an election message and coordinator message is sent to announce the identity of the elected process. The drawing below shows four nodes which containing the data structures, that is A node identity and the number chosen by each nod 13 elected message{1.2.3.4} node 1 elected message {1} {1,2,3,4} {1,2} {1,2,3,4} 22 7 node 4 node 2 elected message{1,2} elected message{1,2,3} 18 node 3 {1,2,3} Figure (Fully Communication Architecture) The assumption of the election start from node 1 and the message is send to all other nodes ; and every process marked as nonparticipant in an election, when node 1 initiates/builds the election message placing with it its identifier which is 13 in active list {1} and sends it to all nodes neighbour, when as election message is received by all nodes, they compare the identifier in the message (13) with their own, consequently node 2 sends reply message to all nodes, because other nodes have lower identifier than it does. On another hand, node 4 does not send any reply message, instead adding all other nodes to its active list; also node 3 sends reply to both node 1 and node 4 but not for node 2; node 1 will reply message only to node 4 due to that the identifier number of node 1 is bigger than node 4. When node 2 sends reply message with its identifier which is the highest one to all nodes, its regarded as coordinator election message, and it will wait a period of time, then if it does not receive any reply from the nodes, thus it sends a message to all other nodes declare itself as coordinator. Node status is normal except while the node is in the process of joining a new group. Each node that is not the leader of a group call to checks whether the leader of its group is still alive, by sending a message to the leader and waiting for a reply. If the node does not receive a reply within the timeout period, the node invokes a recovery procedure. Each leader i call a check procedure, which sends message to every other node asking whether that node is a leader. If one or more other nodes reply that it is a leader, node i pauses for a time inversely proportional to its priority (this helps prevent multiple nodes from initiating elections concurrently) and then calls a merge procedure. The merge procedure sends message to all of other leaders, inviting them to join a new group with the inviting node as leader. When the leader i receives an invitation, it forwards the invitation to the other members of its group. A node i that receives an invitation (directly or indirectly), sends an accept message to the proposed leader of the group. If node I receives a reply to its accept message within some time-out period, then node i joins the new group, otherwise, node i calls the recovery procedure. If two nodes are in the same group, then they have the same leader at all times, for all operational node i and j, if status i = normal and status j = normal. Reliable Broadcast To ensure essentially that all correct processes deliver the same message, and that messages broadcast by correct processes are delivered. Furthermore, it ensures that no different messages with the same identifier are delivered. The consideration that, the reliable broadcast is executed by function broadcast (message) as the following: Reliable broadcast1 Validity: If a correct process broadcast message M, then some correct processes eventually deliver M. Reliable broadcast2 Agreement: If a correct process delivers a message M, then some correct processes eventually deliver M. Reliable broadcast3 Integrity: For any identifier ID, every correct process p delivers at most one message M with identifier ID, and if sender (M) is correct then M was previously broadcast by sender (M). The election message will use the flag, so the flag is used by application to inform which node is alive or dead, and below there is some assumption for that Comments on the core Algorithm First of all, the design in these algorithms have been influenced by Because the sender It long words here Amer Evolution on the core Algorithm Software Development When the choice of the design has made, and finishing the messages passing communication mechanism for the election algorithm. Furthermore, after final manner for the communication topology has chosen and proved , some technical and technology materials are required to reach the goal of this dissertation, like which kind of library and hardware to be used to implement, run and test the algorithm, also which language to be easy for the programming. Thus, the following sections discuss these issues. The C Language The simplicity of C language to learn, understand, and the advantage of its widely spread led me to make the choice to be adapted it as a programming language for the code of this project. Moreover, it is origin as the language of UNIX operating systems. This also gives more advantage as PVM library written in C, so it specifies a standard library with an extensive set of function that being powerful and efficient language. It is support low level of both applications the distributed and the network one. The Cluster Computers A computer cluster is a set of connected or linked computers that working close to each other through high speed local area networks to form a single computer. A cluster at least has two computer that called nodes, one master which typically has a job scheduler that arrange the work to slave

african hair styles :: essays research papers

African hair sculpture is what they call it and Africa and to them it is an art. Africans hardly ever leave their hair or their body plain or in the book, it says â€Å"natural† state. It says that they spend a lot of time and energy on grooming and self-admiration. Sounds like it’s the same way there as it is here because I love to â€Å"groom.† Ha ha. Anyway, it says they spend a lot of time on their hair and looks but special attention to their hair. The â€Å"art† of hairdressing was practiced mostly for women and male hairdressers can hardly be found. The book says that the skill of hairdressing has been handed down from generation to generation and requires artistry, manual dexterity, and patience because many of their styles are elaborate and time-consuming. For most African women hair is a medium for creative self-expression. Now their hair is styled for many different reasons. In some parts of Africa, hairstyles help to determine age, in others ceremonial occasions are marked by special styles. The design and construction of hair depends on different factors, some hair styles may need sisal, clay, the bark of trees, or cloth pads; in other cases it could involve intricate knitting, braiding, and threading of the hair. The most complex styles can take up to several hours and sometimes even days. That’s true here also and we got it from them. The slave master’s wife’s would watch the women braid the kids and each other’s hair and would want their hair to be the same as theirs because the styles were so beautiful. Anyway, they found that you could find complex styles only in the interior of the continent where people still live "primitive" and they have time for all that stuff. In urban areas, the styles are simpler where they have adopted western styles. OK, if you draw a line running from Dakar, Senegal in the west and to Khartoum, Sudan in the east you will see that to the north of the line live the light-skinned, straight-haired Hamites and Semites of North Africa. These would have been the so called â€Å"house slaves† or could even be passed of as being white in some cases. Around the dividing line, the people would have been brown-skinned and would have had curly hair because of Semite or Hamite intermixtures. They were in the middle of everything, they were not house slaves and not in the field just there, but doing work nonetheless. african hair styles :: essays research papers African hair sculpture is what they call it and Africa and to them it is an art.

Ancient South American Foodways Essay examples -- Domestication, Plant

Ancient South American Foodways Domestication of plants and animals has long been indicated as a main causational factor for population increase and socio-political complexity. Evidence of domestication of plants in South America has been said of have initially occurred 8000 BC, evidence of squash in Ecuador (Pearsall 2008:107), and 500 years earlier lima beans and chili peppers are being exploited (Lynch 1983:125-6). However, it took several millennia for intensive manipulation of plants to become standard practice for subsistence. The Archaic transition occurred around 3000 BC was identifiable for its â€Å"broadly based subsistence, experimental agriculture, seasonal nomadism giving way to sedentism, and technological proliferation† (Lynch 1983:91). By the end of the Paleo-Indian times the shift to agriculture and cultivation came to a head during Pre-ceramic 2500 BC quinoa, maize, gourd, squash, potato, beans and lucuma were now utilized for agricultural domestication—the Formative stage according the Lynch (1983:91) ca. 2000 BC had â€Å"intensive agriculture, full sedentism, class systems, corporate labor projects, and temple-based religions.† Before and continuing through the advent of irrigation agriculture, South Americans diets and main source of protein was marine based. â€Å"Fishing is very nearly as old in the new world as the presence of humans—seafood not just agriculture underwrote the first formation of Andean Civilization† (Isbell, Sandweiss, Silver 2008:147). Small sea villages eventually provided a mutual trade system for larger complex towns—exchange of maritime resources for agricultural products. The advent of irrigation agriculture was vital in the formation of complex villages. The trajectory of irrigation in Sou... ...ithin and without the temple precincts, Chavin possessed elements which were to became standard in later Andean cities† (Bruhns, 1994:131). Also, Chiripa located near the Southern end of Lake Titicaca (600-100 BC), because a model for later temple structures particularly the Kidder Temple at Pucara. The site consisted of rectangular buildings around a central patio and each site in the complex housed a sunken rectangular temple. Consistencies across Nazca settlement patterns indicate urban planning strategies and monitoring systems. The Incan culture derived from Tiwanaku. Incan empire expanded from its core, Cuzco in the Cuzco Valley. Incan’s ability to cultivate and harvest resulting in techniques for food storage that could last from 3-7 years. Inca’s took the crops of those conquered nations and cultivated them ensuring seasonality differentiation abundance.

Indicate a Person who has had a Significant Influence on you, and Describe that Influence

Cholera is an infectious disease that causes severe watery diarrhea, which can lead to dehydration and even death if untreated. It is caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae. Cholera was prevalent in the U.S. in the 1800s before modern water and sewage treatment systems eliminated its spread by contaminated water. Only about 10 cases of cholera are reported each year in the U.S. and half of these are acquired abroad. Rarely, contaminated seafood has caused cholera outbreaks in the U.S.However, cholera outbreaks are still a serious problem in other parts of the world, where cholera affects an estimated 3 to 5 million people and causes more than 100,000 deaths each year. The disease is most common in places with poor sanitation, crowding, war, and famine. Common locations include parts of Africa, south Asia, and Latin America. If you are traveling to one of those areas, knowing the following cholera facts can help protect you and you r family.Cholera CausesVibrio cholerae, the bacterium that causes cholera, is usually found in food or water contaminated by feces from a person with the infection. Common sources include:Municipal water supplies Ice made from municipal water Foods and drinks sold by street vendors Vegetables grown with water containing human wastesRaw or undercooked fish and seafood caught in waters polluted with sewage When a person consumes the contaminated food or water, the bacteria release a toxin in the intestines that produces severe diarrhea. It is not likely you will catch cholera just from casual contact with an infected person.Cholera SymptomsSymptoms of cholera can begin as soon as a few hours or as long as five days after infection. Often symptoms are mild. But sometimes they are very serious. About one in 20 people infected have severe watery diarrhea accompanied by vomiting, which can quickly lead to dehydration. Although many infected people may have minimal or no symptoms, they can still contribute to spread of the infection. Signs and symptoms of dehydration include:Rapid heart rateLoss of skin elasticity (the ability to return to original position quickly if pinched) Dry mucous membranes, including the inside of the mouth, throat, nose, and eyelidsLow blood pressure Thirst Muscle cramps If not treated, dehydration can lead to shock and death in a matter of hours.Yellow fever is caused by a virus. The yellow fever virus is a single-stranded RNA virus that belongs to the Flavivirus genus. After transmission of the virus occurs, it replicates in regional lymph nodes and subsequently spreads via the bloodstream. This widespread dissemination can affect the bone marrow, spleen, lymph nodes, kidneys, and liver, in addition to other organs. Tissue damage to the liver, for example, can lead to jaundice and disrupt the body's blood-clotting mechanism, leading to the hemorrhagic complications sometimes seen with yellow fever. Yellow fever is transmitted to humans by the bite of infected mosquitoes.Various species of Aedes and Haemagogus mosquitoes serve as vectors and are responsible for the transmission to human and nonhuman primates, which serve as reservoirs for the disease. Three transmission cycles for yellow fever have been identified. Sylvatic (jungle) cycle: In tropical rain forests, infected monkeys pass the virus to mosquitoes that feed on them. These infected mosquitoes then bite humans who enter the rain forest for occupational (for example, loggers) or recreational activities. Intermediate (savannah) cycle: In humid or semi-humid regions of Africa, mosquitoes that breed around households and in the wild (semi-domestic mosquitoes) infect both humans and monkeys.The virus can be transmitted from monkeys to humans, or from human to human by the mosquitoes. This is the most common type of outbreak in Africa. Urban cycle: When infected humans introduce the virus into urban areas with large numbers of unvaccinated individuals, infected m osquitoes (Aedes aegypti) transmit the disease from human to human. This form of transmission can lead to large epidemics.

The Tulsa Race Riot and Floridas Rosewood Massacre

The Tulsa ply anarchy and Floridas Rosewoood Massacre In ab issue the 75 years following(a) the Tulsa work Riot, there has been investigation on what has happened in Tulsa on the date may 31 and June 1, 1921. The Tulsa charge Riot was a devastating essence in score where more another(prenominal) had lost their lives, around three hundred with recent investigations, and the Greenwood District of Tulsa was destroyed. The drunken reveller started all all over a racial dis bordere, involving a throng of shameful men trying to keep back a lynching of another black man after he was arrested, that escalated in the worst way leaving over a thousand homeless. by and bywards this horrific event was hid from the public for m all years and is solely cosmos brought to attention within the departed 10 years. The familiarity that was destroyed from burning and destruction from the riot has since been rebuilt and is a tout ensemble changed bea. But it is k flatn there ar st ill harsh feelings about what happened those m either years ago and what little has been do to conduct up for it. No reparations kick in water been made so far those who hasten suffered through the riot and survived and for the hotshots who didnt and their descendents.No one was convicted for his or her participation in the riot and no compensation has been given for the many destroyed homes leaving many mint homeless. The survivors of the riot argon heavy their stories and it is still that they are trying to get the familiarity of this disaster to spread to other places out-of-door of Tulsa to hopefully get something positive out of it weather it be agniseledge for others or something to cope with the grief.This event is not in hi business relationship books and has not even been in fairness talked about within and outside the community until recently. Nothing effective has been done to make up for what wrong has been done to the victims. Which should instanter be ch anged, particularly for the survivors of the incident who are still alive to their tragic story and share the truth that has been under wraps for so many years. Schools around Tulsa are now starting to talk about what happened merely still no where in account statement books or anywhere else is it being taught.Floridas rosewood Massacre of 1923 was an event that occurred because of a rumor of a white charwoman being sexually assaulted by a black man, resulting in at least 10 men killed and most of the African American community of Rosewood devastatingly being burned down except for 2 buildings. In earlier years it was suitable if there wasnt much teasing of the woman or the others that were around during the attack. quite they just took the womans parole for it and ignored any other allegations of what happened.The indorse of what happened spread around the area of Rosewood setting off a gathering of white man searching for an get away convict they assumed was to blame, resulting in the gear up to dying. After many years of this massacre occurring and not being exposed, 50 thousand dollars has been put to the investigation to find out any more data by look through areas that which it has occurred. This, just like the Tulsa Race Riot, was a horrible act of racial violence that responsibility needs to be taken by the state it occurred in.But opposed Tulsa something has been done 7 jillion dollars has been appoint to the remaining living victims and the families of those who are no longer alive to try and make right for what has happened. This Compensation was effective sufficiency but the one of the only slipway to completely make up for what happened is if it was brought to light(a) much sooner, and something was done about what happened many years ago when most of the batch were still alive instead of waiting until now when everyone is dying off.Its understood that community believe waiting until most of the survivors take up passed aw ay and then tell the events of what has happened is loss to be to late. The very few survivors that are left from this event are telling their story because if they dont know one would keep up known the truth as to what happened during that duration of time the massacre occurred. So far both reconciliations wipe out not been effective enough especially for the Tulsa Race Riot. That is why everything is going to be done to bring justice to those who have suffered through these events in history.To make up for what wrong has happened to the people that suffered through the Tulsa scarper Riot an bill of 8 million dollars is going to go to the victims and their families. This is more notes than the Rosewood victims received only because the Tulsa Riot involved a great uphold more of people. This amount is going to be given because of the grief they had to experience from death of the people around them, being homeless, the amount of time it took to get this event any recognition, and having to start their lives over from scratch since their office was destroyed and burned down. thousand dollars leave alone be given to any only research that needs to be conducted for the Tulsa Race Riot so that all information is gathered. Both events will be create verbally about by professional historians to put in to textbooks of all over the rural area when all investigations are complete over time starting where it occurred and then feast to different states due to the costs of spic-and-span textbooks. What is being done is to restore the mixer peace between the state and the victims of these dreary of events that were not accounted for many years so there is no hatred or anything negative between the two.
