Business: Public Relations and Press Release

The website is http://www.jpmorganchase.com/corporate/About-JPMC/about-us.htm. The sender is JPMorgan Chase’s public relations and communications department. Looking at the variety and richness of messages heralding the successes and profitability of the bank, it is obvious that the message is intended for a variety of stakeholders like investors, potential investors, shareholders, customers and potential customers, employees and even its competitors. Analyze the integrated business communication.Integrated business communication is defined as â€Å"†¦the process of planning, executing and evaluating unified messages that create stakeholder relationships and build brand recognition.† (Stuart, Sarow, and Stuart, 2007,p.14) The press release section uses information from public relations, management, organizational changes, marketing and incorporate these into a series of dynamic message that paints a picture of the company as a whole making it possible for stake hol ders to form a comprehensively positive image of the company. For example, if one looks at the press release of April 25th of 2013, one realizes it heralds through its title â€Å"Chase Ranks #1 in Mobile Banking Functionality† a technological milestone that not only places the company ahead of its competitors, but also entices prospective customers who might see this as a plus.In this particular press release,  many stakeholders are targeted at the same time. In another press release dated April 17th 2013 titled â€Å"100.000 Jobs mission Announces 64,628 U. S Veterans hired Through First Quarter2013†, the company uses public relations technique to announce its position as an outstanding responsible corporate citizen through offering employment to a target under-privileged group. This particular release serves also as a public relationship announcement to prospective veterans that employment is done on the spot. This is an image building and publicity stunt that als o targets a wide variety of stakeholders. Assess the media richness of the section.To achieve its communication strategy, the company uses both audio and video presentations, emails, news feeds, downloadable data and links to other pertinent information that may be important sources of enrichment to its readers or stakeholders. Of particular interest is its use of webcasts and live feeds or reproduced information that can be viewed live or at the stakeholders’ convenience by way of archived presentations. Describe how the message is framed.Framing according to Robert Entman is â€Å"selecting, and highlighting some facets of events or issues, and making connections among them so as to promote a particular interpretation, evaluation and /or solution†, (Stuart, Sarow, and Stuart, 2007,p.18). This is exemplified in the very setup of the website and the various breakdown of the message into sections, topics, dates in a coherent and easily accessible way through internet ac cess and other communication tools. For example, the topics are arranged beginning with investor relations, financial information, CIO reports, annual report and proxy, shareholder presentations, corporate responsibility to feedback link in frequently asked questions. A cursory look at the table of contents shows that there is a deliberate attempt at presenting a unified message about the company to its stakeholders that paints a bright light, vision and growth with special attention to the shareholders.Identify opinion leaders.Opinion leaders that are targeted by the communication are shareholders, prospective employees, employees, customers, prospective customers, government regulators, generally known as stakeholders. Make recommendations  for improving word choice.The choice of words while technically appropriate to its audience, may be confusing to the rank and file customer and investor who may not understand the use of technical words. This is seen in the earnings reports, and other communiquà ©s in the website. I would also recommend that concrete words be used to avoid ambiguity. A more simple but concise language devoid of ambiguity, double meaning laden with cramped up facts and data is recommended considering the targeted audience and general public to whom the message is addressed.

Chemistry Lab Experiment: The Flame Test Essay

Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame. HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner, then the colour given off by the flame is due to the metal part of the salt. METHOD: (1)With a heat proof mat under the Bunsen burner, turn the gas on and light up the Bunsen burner with matches. (2)Pour enough Hydrochloric acid into a beaker. (3)Using your wire, dip it into the beaker containing Hydrochloric acid (4)Place it into the flame for a few seconds; this is the cleaning method to avoid contamination of other solutions. If the Bunsen burner flame does not change colour, then your wire is clean and you can proceed to dip it into a metal salt. (5)Dip your wire into a metal salt either the nitrate or chloride and place the wire onto the tip of the blue flame. (6)Observe the change in colour of the Bunsen burners flame and record the observations as you go. (7)As long as you clean the wire as directed in step 3-4 you can proceed into testing the other metal salts. QUESTIONS: Q1: Were there any main difference between the chloride salts and the nitrate salts? If there was please comment on what it was Yes, I had observed some difference between the colour produced from the chloride and nitrate salts present in one flame test. The strontium flame admitted both a similar orange colour, but the strontium nitrate has a much more vibrant dark orange than the strontium chloride. Q2: Suggest reasons why the experiment tested both nitrate and chloride salts? The experiment tested both nitrate and chloride salts to allow us to compare which part of salt is responsible for the colour change of the flame. Q3: Suggest why flames on gas stove burn orange-yellow when a small amount of water boils over onto them? This is due to the chemicals present in the water; such as sodium chloride, calcium ion. The orange-yellow flame admitted could also be due to the ingredients added to the water such as salt. Discussion: When the metal salt is introduced to the flame, the electrons absorb heat energy and can jump into a higher energy level. Because the electrons are now at a higher and more energetically unstable level, they fall back down to their original shell, by doing so visible light is emitted due to the energy release. Name a possible source of experiment error and suggest at least one way to reduce the effect: A possible experimental error that could have effect the result is contamination of metal salts. As directed in the steps you must clean the wire using hydrochloric acid. By doing this you are removing any traces of the previous metal salts that could alter the true colour of the flame produce by a different metal salt. By reusing the same wire at each metal salt, you could reduce the effect. Each wire will be completely free of contamination of other metal salts as it will be exposed to only one metal salt. CONCLUSION: Data collected from the flame test identified that both chloride and nitrogen tested were identical, meaning metal is responsible for the colour produced in the flame. This is evidence that strongly supports my hypothesis; therefore I accept my hypothesis on that basis.

Project - Coursework Example All it would require from a customer or the owner of the bag would be to download an application to his or her mobile phone and have the tracking process enabled henceforth. In order to realize maximize on returns and profits, we would customize or segment the business into various parts based on demography and the behaviors of the customers. For instance, the preference of the youth relative to the tracking device and bags is obviously different from threat of the elderly. The rich would have their devices customized to higher pedigree and specialization, so will the social classes be treated, based on the same criteria. As a matter of fact and principle, the device is critical and important because it serves tow outright roles and functions such as enabling the owner to gauge in advance the weight of bag. It is needless to mention the fact that a person would be saved the embarrassment or inconvenience of shading off extra baggage once one is at the airport in front of people. However, one would also have the added benefit of knowing the actual location of his or her bag at the airport. This comes in the wake of the fact that suitcase mix up are common in airports, especially the busy ones. Similarly, the device would enable the owner to know the weight of the bag or luggage and how much he or she would be charged in case of overload if one is at the airport. This is to ensure that the customer or the owner of the bag would be in the know in case of any eventuality. The device ensures the weight of the suitcase is checked and its location pin-pointed accurately. Given the nature of this business, our initial target market would be travelers in Qatar, where the human traffic and activity at the airport are usually high. This also stems from the fact that the prospects of travelers mixing and losing their bags are usually high in these

Audit Independence Case Study Example | Topics and Well Written Essays - 1500 words

Audit Independence - Case Study Example This paper provides an insightful study into the role played by lack of competition in the audit marketplace in affecting auditor independence and the ways through which it can affect the audit quality. It also sheds light on the solutions actually implemented to resolve this problem as well the ones that have been proposed and yet to be implemented. Lack of competition in the audit marketplace is one of the most significant concerns among the regulators these days. Lack of competition in the audit marketplace refers to the fact that there are big four auditing firms predominantly involved in the provision of accounting services around the world encompassing approximately 78% of the total US publicly trading companies. There is a serious lack of accounting services firms in several markets and usually companies are left with no or few choices as to the selection of company auditor because of domination of these big four firms in their respective markets. For example, KMPG has a dominating position in providing auditing services to financial institutions whereas PricewaterhouseCoopers is dominant in the coal and petroleum industry (Bloom and Schirm, 2005). The events such as Enron and WorldCom led to the widespread notion of audit failure or audit incapacity to act as shareholders representatives and report any problems prevailing in the company. This lack of competition became a concern of crucial importance soon after the incidence of Enron and the termination of Arthur Andersen (Bloom and Schirm, 2005). There have been several causes behind the occurrence of such events that seriously shattered the image of auditing and accountancy service profession and directed the attention of regulators towards the notion of lack of competition in the audit marketplaces. Simunic and Stein (1995) elaborate that the market for professional accountancy services highly lacks competitiveness because of several rigid restrictions imposed by the government such as code of ethics, limit on fees and prohibition of advertisement etc. Such restrictions as well as the dominance of big four firms in the industry has been hampering the advent and success of new firms in the market leading to lack of competition. Apart from that, these firms are also involved in the provision of non-audit professional services to their client companies. Because of that fact that there happen to be a very few number of firms in the market, companies turn towards these four firms for both audit and non-audit professional services. Such involvement also contributes to concentration of a major part of these audit firms' income in the client company. This has been the major factor affecting the independence of auditors in providing an opinion on a client company's financial statements. Hence, lack of competition in the audit marketplace is considered to be acting as a threat to audit independence. Audit independence refers to the notion of complete freedom on the part of an auditor while presenting an audit opinion. Hemraj elaborate that "the function of 'public watchdog' demands that the auditor subordinates

Research proposal Essay Example | Topics and Well Written Essays - 3000 words - 6

Research proposal - Essay Example rious industries, including the UK banking sector is also making vital use of IT networks in their processing of customer services (Ho & Mallick, 2006; Samakovitis, 2006). It is often argued that IT systems hold considerable significance in the building cooperative associations with customer groups that further facilitates better customer serving and hence, contributes to augmented customer loyalty. Both these spectrums, i.e. customer loyalty linked with better customer serving, have been many a time associated with the longevity and continuous expansion of any service sector today, and likely to be apparent in the banking sector as well. Keeping speculations aside, the UK service sector, which is the other dimension in focus of the title chosen for this study, has been reported as growing impressively over the past few years even if its particular drawbacks remain to be consistent (Mullineux, 2012). The three key dimensions of the UK financial sector, vis-Ã  -vis, and its banking sector involve payment services, insurance services against risk and intermediation services between lenders and borrowers. While all these three dimensions present different challenges for the banking institutions in the UK, the continuously changing demands and shifts in the market functions have somewhat forced these banks to build a close and strong relationship with its customers (Davies & et. al., 2010). The particular problems presented by the UK banking services sector have thus been attempted to be resolved with the usage of IT innovations (Aliyu & Tasmin, 2012). Nevertheless, this topic yet remains as negligibly studied among the modern scholars, indicating a gap in the literature obtainable to test such speculations. Hence, emphasizing this gap currently present in the scholar society, the proposed study will aim at deriving firm conclusions on the strength of influences imposed by IT innovations and developments on the UK banking industry. From a mere tool for communication,

Proposal Essay Example | Topics and Well Written Essays - 1000 words

Proposal - Essay Example Therefore, evidence-based practice means combining clinical experience of an individual with the external clinical evidence and this will be able to produce the best evidence, one that is effective in patients care. In this case, the nursing problem uncovered is whether using IVs for procedures gives a positive patient experience compared to the numbing agent. In evidence-based practice, the use of new knowledge and being able to access that knowledge is essential (Mulhall, 1998). Despite several models being developed for the healthcare givers during practice, they still have difficulties in combining the empirical evidence with evidence based changes into practice. To solve this problem practitioners have been provided with a model that guide them through the entire process of being able to change to evidence-based practice and this begins with the assessment of the need for the change to the integration of an evidence-based protocol (Mulhall, 1998). Change plan overview According to Rosswurm and Larrabee (1999), we have six steps that are considered. The first step to be considered is assessing the need for change. Practitioners may only be interested in change if only they become aware of patients preferences, dissatisfactions, quality improvement data, their questions and the evaluation data. In this step, practitioners are required to collect internal data and then be able to compare with external data. When this data indicate a problem, then they will be forced to choose a stakeholder who will be involved in identifying clearly where the problem is. After which the practitioners will examine the internal data and use it to assess the requirement for a change in practice. If information is inadequate, it will be necessary to collect extra data so as to identify a problem (Titler., Kleiber, Stelman, Goode and Buckwalter, 1994). The second step involves linking problem with interventions and outcomes. In this step, practitioners are required to explain the problem using the language of standardized classification and then be able to link this problem with classification of interventions and outcomes. These classifications help to identify the concepts of science and knowledge that is organized. In this case, the use of Lidocaine or normal saline intradermally will be considered as an intervention and English language will be used to explain the process. According to research done by Beck et al (2011) who was comparing pain perceived during intravenous catheter insertion after injection with various local anesthetics, his major aim being to find out whether the anesthetics are effective. This study would then help the researcher to quantify data. This step also helps in facilitating communications between practitioners, and setting standards for showing the effectiveness and cost of care and being able to identify resources needed (Rosswurm and Larrabee, 1999). The third step is simply synthesizing best evidence. This step involves ref inery of selected interventions and outcomes. This is whereby the best research evidence is synthesized, and then it is combined with clinical judgment data. According to the research done, the best evidence is according to Brown (2003) who was using Lidocaine for peripheral IV insertions and the purpose of this research was to find out the patients preferenc

How has commercialisation affected professional football since the Essay

How has commercialisation affected professional football since the formation of the premier league and what effect has this had on the average fan - Essay Example d the 1980s witnessed England entering into a rather novice phase marked by lack of commercial enterprising on the part of sponsors and top brass of soccer administrators. In fact European football in general followed a downward curve during these two decades (King 59). Several key factors were responsible for this lean period in the history of English soccer. These factors ranged from societal issues to lack of technical adroitness. However, the Premier soccer League teemed with the very best from the global arena and players from all continents signed for various clubs featuring in the League (Storey 108), thus turning English club football into an action-packed display of power and dynamism. The focal point of this paper is going to be the period following the formation of the English Premier League, during which the entire skeleton of English soccer underwent a drastic change in terms of growing commercialisation and corporate professionalism. The paper will also discuss the relative position of British soccer in the larger framework of world football in the last two decades. The charm of English soccer ebbed away following the series of poor performances by the national soccer team in FIFA World Cups after their historic win over West Germany in the 1966 version of the premier title. It was imperative for the administrators and players alike to bring people back to where they could relate themselves to. However, due to a pervasive sense of hopelessness prevailing among the average followers of the sport, the task was not an easy one. Moreover, hooliganism was on the rise in the 1980s both on English soil and outside (Dunning and Malcolm 101). In fact English football had earned a notorious distinction of promoting hooliganism across Europe and other soccer playing countries (Bloom and Willard 306). Political reasons also came into contention in this regard as some of the earlier events in the annals of world history were believed to have contributed to the

Elements of a Contract Assignment Example | Topics and Well Written Essays - 1000 words

Elements of a Contract - Assignment Example Ball parks are not included in an offer. It does not request for proposals of a letter of intent. Indicating general intent to launch into a contract and inviting persons, to give their offers is what constitutes an invitation to treat. An offer goes beyond mere display of intent. For instance, displaying cars in a motor vehicle shop together with their prices does not constitute an offer waiting for interested customers to walk in and accept the offer. Rather, it becomes an offer when a customer comes and selects the car of the price they want and goes to pay for it. The motor vehicle seller will then decide to, either accept the offer, or not. A contract that has a high value has a longer time of offer (Blum, 2007). Acceptance Acceptance is an expression by the person who receives the offer that they have accepted it. Acceptance needs to be an absolute and unconditional agreement that a person will abide by the terms spelt out in the offer(Drake, 2007). The person who gave the offe r needs to see to it that the person receiving it has understood it well. It ought to come before the expiry of the period of offer. Otherwise, acceptance can only be valid after the given time of offer has lapsed if the one giving the offer renews that period. Where the time of the offer has been stated as ‘reasonable’, usually, the circumstances of such a case will define what is reasonable. If there are conditions attached to the acceptance or the terms of the offer changes, the involved parties are negotiating. Legal consideration Consideration is needed in order to make the contract valid. Parties exchange promises or make an act as to the agreement. Consideration is what makes such an arrangement binding. Consideration denotes some form of benefit to the one who is making the offer and a corresponding cost to the one accepting the offer. It could be monetary, some form of right or interest. The parties agree on how much consideration is adequate. This consideratio n needs to be something valuable. Such an agreement is subject to the courts deciding whether to enforce it, especially with regard to the adequacy of the consideration(Helewitz, 2007). A past promise cannot be a consideration. It is must either a new promise or benefit in exchange of the offer. Capacity A valid contract is between competent parties. Legal capacity is defined by several factors. There are people who are not free to enter into a valid contract, and their consent is treated specially. People who have mental impairment may not understand the terms of a contract. Legal capacity of mentally impaired people will largely depend on whether there is a genuine consent. Since consent depends on an individual’s understanding of a contract, the complexity or simplicity of a contract matters(Burton, 2009). Courts may have to come in if it is established that the individual who was making the offer knew of the disability of the contracted person and was out to take advantag e of them. The contract can also be suspended if the benefit that the second party received has not been sold to another that was not involved in the contract. If it had been sold, the third party is informed of the possible outcomes so as not to be bound by the contract. There are some people with mental impairments who are assisted by administrators that are legally appointed for them. Such people cannot enter contracts freely

Process of Economic Integration in the World Today Essay

Process of Economic Integration in the World Today - Essay Example This paper presents a modern research report on different aspects of economic integration in the world today. The prime purpose involved in the process of economic integration process is reducing costs both for the producers and the consumers as well. The increasing levels of integration help in determining the competitiveness and allowing smooth movement of labour, cost and capital. It can be affirmed that the implementation of economic integration lessens the short-term profits due to the imposition of tariffs. Economic integration reduces the other trade barriers as well. It gives less power to the government of the member nations to make necessary adjustments that might deliver significant benefits to them. The process of economic integration in the context of E.U. generally includes four main features. One of the features is that economic integration reflects increase in intra-euro area trade at large. The second facet of economic integration can be identified to be making smooth and free flow of capital and also contributing towards developing the aspect of financial integration. The third feature of economic integration relating to its process is constituted by labour mobility. The other facet of economic integration in relation to its process can be viewed as synchronizing and coordinating different cyclical positions across the Euro areas It can be apparently observed but deeper economic integration is needed for the creation of developed economy in this increased level of globalisation along with internationalisation. ... These figures reflect the creation of strong Europe (European Central Bank, 2007). The second facet of economic integration can be identified to be making smooth and free flow of capital and also contributing towards developing the aspect of financial integration. Financial integration strengthens the economic mechanism, raises the competition and increases the potential for stronger economic growth. Along with economic integration, financial integration plays an imperative role in determining effective monetary policies and ensuring free along with effective transmission of single monetary policy. However, the actual need of financial integration is being observed in retail banking sector (EUbusiness Ltd, 2013). The third feature of economic integration relating to its process is constituted by labour mobility. As the labour market begins to tighten itself in developing economies, absence of openness may result in generating the risks of wage pressure. In most part of the European U nion, it can be viewed that cross border labour mobility is still limited, restricting in developing the economy by a certain degree through the emergence of regulatory barriers. The other facet of economic integration in relation to its process can be viewed as synchronizing and coordinating different cyclical positions across the Euro areas (Kuroiwa, 2012). Purposes of Economic Integration In order to determine the purposes of economic integration, it can be apparently observed that economic integration has increased among the countries in the European Union, but deeper integration is needed for the creation of developed economy in this increased level of globalisation along with internationalisation. In this similar context, the prime

Sustainable Talent Management Essay Example | Topics and Well Written Essays - 1750 words

Sustainable Talent Management - Essay Example A good work environment, proper relationships and effective compensation are among the preferred and effective motivational strategies which are commonly used by managers and organizational leaders to enhance performance (Seiden & Sowa, 2011). The contemporary work environment is characterized by diversity and influence by the forces of globalization, the two factors which are argued to be justification for effective performance management processes. This paper presents the concept of performance management with a critical review, analysis and discussion of the process of managing employee performance, the review of talent, the global aspects of talent management and recommendations for a sustainable process of talent management. Performance Management Process In the measurement of employee talent, the process of performance management is often employed. Performance management process is described as a specific methodology through which the design of an organizational management is e xecuted with a purpose of ensuring that all elements within the organization are working with a common focus of meeting organizational objectives and goals (Moczydlowska, 2012). Performance management process also plays an important role of ensuring optimization of the strategic goals of an organization (Agbola, Hemans & Abena, 2011). The elements or component of the organization which are involved in performance management process include the departments within the organization, talent or human resource, work processes and activities and groups and teams (Ahmadi, Ahmadi & Abbaspalangi, 2012). Therefore the most effective design of performance management process that is recommended for measurement of employee talent is that which is designed with a view of incorporating all organizational components with a sole purpose of optimizing the overall performance of the organization. Employee talent is normally measured in terms of current performance and potential for future performance ( Seiden & Sowa, 2011). This process involves several activities which are aimed at measuring the propensity of an employee or talent to become productive and beneficial for the organization (Glykas, 2011). Firstly, the goals of performance management and measurement of talent are set. The goals of talent measurement relates to the expected outcomes that are expected to emanate from the process of determining the performance of talent. Secondly, standards are set by the management which is used to measure the results and work outcomes or outputs of organizational talent. These standards act as a guideline or framework within which the work activities of the employees are measured (Moczydlowska, 2012). This means that failure to meet the standards reflects that the performance of talent is below the expectations of the organization. Thirdly, the progress of talent towards the achievement of the preset goals is done. This process represents the role of organizational leadership or manag ement team (Durovic, 2012). Fourthly, feedback is presented to the talent on their performance including the decisions that are reached by the management as motivated by the talent measurement outcomes. In the contemporary business environment, performance management software applications are used to enhance the process of talent measurement to ensure effectiveness and accuracy. Talent Pools and Review In the management of talent, the leadership and management team within an

Political development Essay Example for Free

Political development Essay There are many more important factors to human activity than leadership. Effective leadership helps our nation through times of danger and risky situations. In today’s competitive world, leadership skills are crucial for both personal and professional development. Leadership is an important function of management which helps an individual or a business to maximize efficiency and to achieve goals. It makes a business and/or nonprofit organization successful. Leadership is a very important trait of management which helps an individual or a corporate business to maximize efficiency and achieve their goals. Leadership has different meanings to various people. Most commonly, leadership is also defines as influence, that is the art influencing others so that will strive willingly towards reaching goals. Political leadership is a more complex process by which the persons in power influence their followers, society, and the public to accomplish their set goals for the community. Political leaders are necessary for continuing and starting the process of change and development in any society. It can be social or economic change and constitutional or political change. These leaders carry out the process of change by applying their skills and attributes like politically relevant beliefs, socially adored values, and approved character. Political development is an interactive, public-decision-making and learning process that alters the achievable set of options open to solving political problems within and between government and civil society, based on power creation and dispersion. This process leads to increasing individual and group autonomy from below from above. The study of Political Development can also be understood as the structures of the state in correspondence with the changes occurring in the economy and social dimensions of group life. The concept of political development should be based on an open acknowledgement of the value of institutional autonomy and its relationship to democratic values. Without any leadership and developing of societies, groups of human beings quickly turn into arguments and conflict, because we see things in different ways and lean towards different solutions.

Sociology of Food in USA

Sociology of Food in USA Sociology of food in USA INTRODUCTION Man and food have close association with one another and this association has also compelled the man to find new means and new forms of food, to bring diversity and sustainability in their food chain. Initially the food was only grown like vegetables and fruits or was got, in the form of meat, of hunting animals. With the progress in civilization and the technology, all phenomenon of production, distribution and consumption changed and with this change raised the issue like health, ethical, environmental, labor and the cultural. When these issues came into focus, the whole scenario brought the field of sociology of food. This field helps to study how the food is currently produced, then goes to the line of distribution and how the people around the country or the world consume it. Along with all other factors, this whole process of food chain also has the social impact and this impact can affect the society in a number of ways. Here, we will discuss the sociology of food in USA and h ow it is creating social problems. OBJECTIVE PRESENTATION OF THE SOCIAL CONDITION In the countries like America, it is not an ancient thought that food used to be cooked at home and was considered as the item that connects the family together and helps them to sit together and interact with each other. It was once the preference that food should be prepared at home and the preparation of food itself required a lot of fresh ingredients and specially loves. After the industrial revolution, along with other concepts, the idea of food as the bonding force also changed. Industrial revolution not only increased the speed of progress in science and technology, but also, altered the pace of life. Industrial revolution also gave the opportunity to work, therefore, most of the members of the family started working. People became busy in earning money and cooking meals at home became difficult for the people and as a result the food industry progressed to an extent that it has taken the place in every home of United States. Food production, distribution and consumption have become one of the biggest industries not only in United States, but, all over the world. SUBJECTIVE PRESENTATION OF WHY THE SOCIAL CONDITION IS A SOCIAL PROBLEM Although we are now living in the society which revolves around becoming self-sufficient and economically stable, therefore, people have to spend more time at workplaces, thus, decreasing the time people used to spend their time. Most of that time was centered on making and feeding family members. The abundance of readymade food including: fast food drinks and junk food provided a lot of solutions for the people. Food is an important source to create connections and it is considered that cooking and serving proper meals reestablishes and reinforces the bond between different members of the family and helps them to send time with one another (Debevec and Tivadar). Taking, cooking of food out of our daily lives is causing a lot of social issues, that dominating our way of living and relationships. Food Production Five decades back, the production of food had never been an issue. Countries usually depended on their own main crops to meet the needs of their population, but, with the passes of time, transportation, technology, wealth and prosperity of some countries gave those changes to get more and better food for their population. One example is that Asian countries are acquiring land in African countries. This method of production, in foreign countries is to meet the increasing need of the Asian countries to fulfill the demand of the food, due to increase in population in urban areas. This will not only create social issue for the people of African countries, but, also in the countries this food is consumed because the excessive export of the crops of African countries will put pressure on the society because people will not be able to benefit from their own land, thus creating social distress. Also, the people in Asian countries, who will be consuming those products, will have to pay more f or it due to increase in cost due to transportation. Thus, a social divide will occur because people of middle and lower classes will have to pay more, even beyond their means, to get the articles of basic need (Gunasekera and Finnigan). Secondly, with the advancement of technology, transgenic technology is used to genetically modified crops or the improved crops. This technology is used all over the world, but, still there are societies which consider them against their beliefs and system. There are societies who collectively thing that producing food by introducing foreign agent into the original form might have negative impact on the health of the people and the originality of the crops. People believe that since all the crops grown naturally are the best form of the food and it is not for the benefit of society to genetically enhance the food and increase production, which might compromise the health of the people, which will ultimately reflect on society (Akumo and Riedel). Thi rdly, sustainability has also become an important issue in food production. With increase in population, demand of dietary products and meat has increased and in order to meet the needs several scientific methods are used. Eight hundred million people in the world are suffering from malnutrition, whereas, nearly four hundred million people are obese. The increase in prosperity and population has increased the demand of these products, but, in order to raise more meat giving animals, more water and food for them is needed. This causes an imbalance in the environment because there is already sacristy of the water and the food of these animals need to grow and this excessive requirement compels humans to use unnatural ways to grow food and even increase the speed of growth of animals. Demand of these food items has increased, but, so does their price and the prices of these products are getting out of reach of common people, especially in underdeveloped countries. This also crease soci al imbalance and the working class again has to suffer due to lack of finances. (Reisch and Eberle) Food Distribution Food distributions systems work as the network and distribute food products all over the country. The supply of food actually depends on the demand of the product in a certain area, but, certain food items are produced that may be demanded in different markets comprising of variety of social classes and this different in social status may also affect the availability of the product. The availability of these products is also dependent on the purchasing power of the customer. There the distribution is also affected by this, thus making these products unavailable to the lower class (FAO). The main issue associated with the distribution systems is that there are very less number of markets that sell their products locally. Since, these products are sent to other towns and cities, thus increasing the price of the product. The excessive spending on distribution and the money spent on advertising is received from the consumer, which again impacts the working class of the society (Martinez, Hand and Pra). The people who used to come at the churches pantry to get food have increased three times since 2008. But, the amount of food that was distributed to these services has decreased due to decrease in budget. Thus this uneven supply of food to these church services have put the pressure to the churches to feed the peed that are deserving and are dependent on them. Uneven distribution of food and makes people unable to purchase their own food (Greenberg, Greenberg and Mazza). Food Consumption The consumption of the food is greatly influenced by the income of the consumer. The families that have better income spend a lot of money on food and especially on fancy and expensive food items. Therefore, a social divide is also created and the food items are produced which can only be consumed by the people who are financially stable (Jappelli and Pistaferri). Due to busy lifestyles the eating out and consuming readymade food is increasing rapidly in the country. Although, research show that the food that is made and eaten at home has good health and social effects. At the dinner table, family get the chance to interact with each other, develop better relationship and come to know about lives of one another, thus creating better family bond and increasing harmony in the society (Eisenberg, Olson and Neumark-Sztainer). Since the people consume a lot of food outside, therefore, their choice of food is also affected by the people around them. People who eat at the public places usua lly eat unhealthy and fatty food and most of the times they spend more money, than their average spending, this results in compromised health and finances. The obese and financially unstable people further affects the balance of the society (Mcferran, Dahl and Fitzsimons). SOCIAL CHANGE Food production industry has changed its shaped since last eight decades and now everything that was considered the specialty of home foods come in packing. Income has increased the demand for expensive food items and the food market has become global. All these factors are affecting the society because transportation from far off places makes, even the most common things expensive, thus making it expensive for major portion of society. This problem can be reduced by introduced more local markets and by promoting local products. Moreover, alternative products to protein like second level protein should be encouraged and produced, to meet the needs of the people. Pulses can also serve as the alternative source for protein; therefore, producing this item can help in achieving sustainability in food chain. Food distribution has always been the issue all over the world, but, now we come to see even the global distribution of food. Now even the food of Sydney can reach any part of the world. Still there are countries that are facing uneven distribution of food resulting on malnutrition. Uneven distribution is also due to the uneven incomes of different segments of the society. Also different markets have different prices of same item and even. This problem can be solved by introducing centralized distribution system and centralized pricing. These systems can even help the working class to afford all things and everything can become available to everyone, irrespective of the social class. Also, this centralized system will be helpful in ensuring that every member of the society is equally treaty and has access to everything he needs. The consumption of food can only be controlled by the consumer. The most important should be the heath of the customer, for which customer should take balanced diet and this diet could help to give better and healthy people to the society. People should also, consider the effect of decrease in family meal on their social and family life.. There should be balance in work and family life and the increase in social distress can be caused if this balance is disturbed. Although, it is easier and simpler to get the food from restaurants, but, restaurants cannot compensate for the love of the family and communication with family members. Also, most of the times, the food consumed outside is unhealthy and unhygienic, that can result in a health issue, will demand money for seeing a physician and will put extra pressure on the finances. The government should also conduct awareness programs about the importance of meals made at home and the significance of balanced diet. CONCLUSION Sociology of food is an important topic and sociology of food in USA is also. Three different aspects of food chain: production, distribution and consumption. There are a number of social issues in all three aspects and the most prominent ones are due to uneven income of different segments of the society. So, in order to meet the most common needs of all the people, it is important to have if not centralized then controlled system that can ensure that all markets have same price. Moreover, the consumption of the food should also be according to the needs of the body and excessive or unbalanced. A lot work has to be done to the sociology of food in United States in all three areas i..e production, distribution and consumption. Works Cited Akumo, Divine Nkonyam and Heidi Riedel.

Polyisobutylene Applications

Polyisobutylene Applications Fuel and lubricant additive. Polyisobutylene (in the form of polyisobutylene succinimide) has interesting properties when used as an additive in lubricating oils and motor fuels. Polyisobutylene added in small amounts to the lubricating oils used in machining results in a significant reduction in the generation of oil mist and thus reduces the operators inhalation of oil mist.[2] It is also used to clean up waterborne oil spills as part of the commercial product Elastol. When added to crude oil it increases the oils viscoelasticity when pulled, causing the oil to resist breakup when it is vacuumed from the surface of the water. As a fuel additive, polyisobutylene has detergent properties. When added to diesel fuel, it resists fouling of fuel injectors, leading to reduced hydrocarbon and particulate emissions.[3] It is blended with other detergents and additives to make a detergent package that is added to gasoline and diesel fuel to resist buildup of deposits and engine knock.[4] Polyisobutylene is used in some formulations as a thickening agent. [edit]Sporting equipment Butyl rubber is used for the bladders in basketballs, footballs, soccer balls and other inflatable balls to provide a tough, airtight inner compartment. [edit]Roof Repair Butyl rubber sealant is used for rubber roof repair and for maintenance of roof membranes (especially around the edges). It is important to have the roof membrane fixed, as a lot of fixtures (i.e., air conditioner vents, plumbing and other pipes, etc.) can considerably loosen it. Rubber roofing typically refers to a specific type of roofing materials that are made of ethylene propylene diene monomers (EPDM). It is crucial to the integrity of such roofs to avoid using harsh abrasive materials and petroleum-based solvents for their maintenance. Polyester fabric laminated to butyl rubber binder provides a single-sided waterproof tape that can be used on metal, PVC, and cement joints. It is ideal for repairing and waterproofing metal roofs. [edit]Gas masks and chemical agent protection Butyl rubber is one of the most robust elastomers when subjected to chemical warfare agents and decontamination materials. It is a harder and less porous material than other elastomers, such as natural rubber or silicone, but still has enough elasticity to form an airtight seal. While butyl rubber will break down when exposed to agents such as NH3 (ammonia) or certain solvents, it breaks down more slowly than comparable elastomers. It is therefore used to create seals in gas masks and other protective clothing. [edit]Chewing gum Molecular structure: Rubber Chemical Structure Introduction to rubber chemical structure: In the organic chemistry section of chemistry ,we learn about the various polymers , monomers,elastomers etc.Monomer is a single unit and when huge number of monomers are combined or say polymerised then polymers are formed.The process of conversion of monomer to polymer is known as p-olymerisation.Elastomer is an another category of polymers having a specific properties of regaining of its structure even if it is stretched.Rubber comes under the category of elastomer.In general life rubber has variety of uses.the important property of rubber is that it regains its structure even if it is stretched.Stretching can be done up to a certain limit.If it is stretched beyond limit then it can break. Rubber can be found in two forms 1)Natural rubber 2)Synthetic Rubber Natural rubber is a kind of rubber which which is found directly from the nature.And when the natural rubber is processed under some chemical processes then a new kind of rubber is formed ,this rubber is known as synthetic rubber.We can also say that natural rubber are synthesised from the natural rubber.Both this rubber are of great use because of its specific features. Structure of rubber: Main composition of crude rubber is hydrocarbons.It also contains some proteins and materials which are soluble in acetone.The hydrocarbons which possess the properties of rubber are usually high in molecular weight and it ranges from 45000 to 3000000.Isoprene is a monomer of natural rubber.When huge number of isoprene units are polymerised then a polymer is formed . Cis and Trans Configuration of Rubber The cis configuration of the natural rubber is the reason for the rubber properties in it. Cis configuration means that extension of the chain is on the same side of the ethylene bond.If the configuration is trans, it means that the extension of chain is on the both sides of ethylene bond,then it is a hard plastic.In case of trans it does not show the properties of rubber. Synthetic rubber is of great use in the industry.Some of the widely used synthetic rubber are butyl rubber which is formed by the copolymerisation of isobutylene and a little amount isoprene.Another synthetic rubber is Styrene Butadiene Rubber also known as SBR.Buna N and buna S is also a kind of synthetic rubber often use in the industry. Vulcanisation of Rubber In the rubber molecules the cross linking between the chains are very less.This leads to the softness in the rubber .To make the rubber hard some chemicals are added to it.The process is known as vulcanisation.In this process the natural rubber is treated with some chemicals ,more often chemical used is sulphur.When sulphur reacts with the natural rubber then it increases the cross linking between the molecules in the rubber.It also forms many sulphide bonds.Due to formation of many new crosslinkings and many sulphide bonds the natural rubber becomes hard.Natural rubber is a kind of thermoplastic,it means that it becomes soft when it is subjected to heat and it becomes hard when it is subjected to cold. butyl rubber (IIR), also called isobutylene-isoprene rubber, a synthetic rubber produced by copolymerizing isobutylene with small amounts of isoprene. Valued for its chemical inertness, impermeability to gases, and weatherability, butyl rubber is employed in the inner linings of automobile tires and in other specialty applications. Both isobutylene (C[CH3]2=CH2) and isoprene (CH2=C[CH3]-CH=CH2) are usually obtained by the thermal cracking of natural gas or of the lighter fractions of crude oil. At normal temperature and pressure isobutylene is a gas and isoprene is a volatile liquid. For processing into IIR, isobutylene, refrigerated to very low temperatures (approximately à ¢Ã‹â€ Ã¢â‚¬â„¢100  °C [à ¢Ã‹â€ Ã¢â‚¬â„¢150  °F]), is diluted with methyl chloride. Low concentrations (1.5 to 4.5 percent) of isoprene are added in the presence of aluminum chloride, which initiates the reaction in which the two compounds copolymerize (i.e., their single-unit molecules link together to form giant, multiple-unit molecules). The polymer repeating units have the following structures: Because the base polymer, polyisobutylene, is stereoregular (i.e., its pendant groups are arranged in a regular order along the polymer chains) and because the chains crystallize rapidly on stretching, IIR containing only a small amount of isoprene is as strong as natural rubber. In addition, because the copolymer contains few unsaturated groups (represented by the carbon-carbon double bond located in each isoprene repeating unit), IIR is relatively resistant to oxidation-a process by which oxygen in the atmosphere reacts with the double bonds and breaks the polymer chains, thereby degrading the material. Butyl rubber also shows an unusually low rate of molecular motion well above the glass transition temperature (the temperature above which the molecules are no longer frozen in a rigid,glassy state). This lack of motion is reflected in the copolymers unusually low permeability to gases as well as in its outstanding resistance to attack by ozone. The copolymer is recovered from the solvent as a crumb, which can be compounded with fillers and other modifiers and then vulcanized into practical rubber products. Owing to its excellent air retention, butyl rubber is the preferred material for inner tubes in all but the largest sizes. It also plays an important part in the inner liners of tubeless tires. (Because of poor tread durability, all-butyl tires have not proved successful.) IIR is also used for many other automobile components, including window strips, because of its resistance to oxidation. Its resistance to heat has made it indispensable in tire manufacture, where it forms the bladders that retain the steam or hot water used to vulcanize tires. Bromine or chlorine can be added to the small isoprene fraction of IIR to make BIIR or CIIR (known as halobutyls). The properties of these polymers are similar to those of IIR, but they can be cured more rapidly and with different and smaller amounts of curative agents. As a result, BIIR and CIIR can be cocured more readily in contact with other elastomers making up a rubber product. Butyl rubber was first produced by American chemists William Sparks and Robert Thomas at the Standard Oil Company of New Jersey (nowExxon Corporation) in 1937. Earlier attempts to produce synthetic rubbers had involved the polymerization of dienes (hydrocarbon molecules containing two carbon-carbon double bonds) such as isoprene and butadiene. Sparks and Thomas defied convention by copolymerizing isobutylene, an olefin (hydrocarbon molecules containing only one carbon-carbon double bond) with small amounts-e.g., less than 2 percent-of isoprene. As a diene, isoprene provided the extra double bond required to cross-link the otherwise inert polymer chains, which were essentially polyisobutylene. Before experimental difficulties were resolved, butyl rubber was called futile butyl, but with improvements it enjoyed wide acceptance for its low permeability to gases and its excellent resistance to oxygen and ozone at normal temperatures. During World War IIthe copolymer was called GR-I, for Government Rubber-Isobutylene. LINKS Related Articles Top of Form Polymers 1. Introduction Prior to the early 1920s, chemists doubted the existence of molecules having molecular weights greater than a few thousand. This limiting view was challenged by Hermann Staudinger, a German chemist with experience in studying natural compounds such as rubber and cellulose. In contrast to the prevailing rationalization of these substances as aggregates of small molecules, Staudinger proposed they were made up of macromolecules composed of 10,000 or more atoms. He formulated a polymeric structure for rubber, based on a repeating isoprene unit (referred to as a monomer). For his contributions to chemistry, Staudinger received the 1953 Nobel Prize. The terms polymer and monomer were derived from the Greek roots poly (many), mono (one) and meros (part). Recognition that polymeric macromolecules make up many important natural materials was followed by the creation of synthetic analogs having a variety of properties. Indeed, applications of these materials as fibers, flexible films, adhesives, resistant paints and tough but light solids have transformed modern society. Some important examples of these substances are discussed in the following sections. art 2. Writing Formulas for Polymeric Macromolecules The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE). HDPE is composed of macromolecules in which n ranges from 10,000 to 100,000 (molecular weight 2*105 to 3 *106 ). If Y and Z represent moles of monomer and polymer respectively, Z is approximately 10-5 Y. This polymer is called polyethylene rather than polymethylene, (-CH2-)n, because ethylene is a stable compound (methylene is not), and it also serves as the synthetic precursor of the polymer. The two open bonds remaining at the ends of the long chain of carbons (colored magenta) are normally not specified, because the atoms or groups found there depend on the chemical process used for polymerization. The synthetic methods used to prepare this and other polymers will be described later in this chapter. Unlike simpler pure compounds, most polymers are not composed of identical molecules. The HDPE molecules, for example, are all long carbon chains, but the lengths may vary by thousands of monomer units. Because of this, polymer molecular weights are usually given as averages. Two experimentally determined values are common: Mn , the number average molecular weight, is calculated from the mole fraction distribution of different sized molecules in a sample, and Mw , the weight average molecular weight, is calculated from the weight fraction distribution of different sized molecules. These are defined below. Since larger molecules in a sample weigh more than smaller molecules, the weight average Mw is necessarily skewed to higher values, and is always greater than Mn. As the weight dispersion of molecules in a sample narrows, Mw approaches Mn, and in the unlikely case that all the polymer molecules have identical weights (a pure mono-disperse sample), the ratio Mw / Mn becomes unity. The influence of different mass distributions on Mn and Mw may be examined with the aid of a simple mass calculator. To use this device Click Here. Many polymeric materials having chain-like structures similar to polyethylene are known. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers. A listing of some important addition polymers and their monomer precursors is presented in the following table.

Properties of Macromolecules A comparison of the properties of polyethylene (both LDPE HDPE) with the natural polymers rubber and cellulose is instructive. As noted above, synthetic HDPE macromolecules have masses ranging from 105 to 106 amu (LDPE molecules are more than a hundred times smaller). Rubber and cellulose molecules have similar mass ranges, but fewer monomer units because of the monomers larger size. The physical properties of these three polymeric substances differ from each other, and of course from their monomers. à ¢Ã¢â€š ¬Ã‚ ¢ HDPE is a rigid translucent solid which softens on heating above 100 ° C, and can be fashioned into various forms including films. It is not as easily stretched and deformed as is LDPE. HDPE is insoluble in water and most organic solvents, although some swelling may occur on immersion in the latter. HDPE is an excellent electrical insulator. à ¢Ã¢â€š ¬Ã‚ ¢ LDPE is a soft translucent solid which deforms badly above 75 ° C. Films made from LDPE stretch easily and are commonly used for wrapping. LDPE is insoluble in water, but softens and swells on exposure to hydrocarbon solvents. Both LDPE and HDPE become brittle at very low temperatures (below -80 ° C). Ethylene, the common monomer for these polymers, is a low boiling (-104 ° C) gas. à ¢Ã¢â€š ¬Ã‚ ¢ Natural (latex) rubber is an opaque, soft, easily deformable solid that becomes sticky when heated (above. 60 ° C), and brittle when cooled below -50 ° C. It swells to more than double its size in nonpolar organic solvents like toluene, eventually dissolving, but is impermeable to water. The C5H8 monomer isoprene is a volatile liquid (b.p. 34 ° C). à ¢Ã¢â€š ¬Ã‚ ¢ Pure cellulose, in the form of cotton, is a soft flexible fiber, essentially unchanged by variations in temperature ranging from -70 to 80 ° C. Cotton absorbs water readily, but is unaffected by immersion in toluene or most other organic solvents. Cellulose fibers may be bent and twisted, but do not stretch much before breaking. The monomer of cellulose is the C6H12O6aldohexose D-glucose. Glucose is a water soluble solid melting below 150 ° C. To account for the differences noted here we need to consider the nature of the aggregate macromolecular structure, or morphology, of each substance. Because polymer molecules are so large, they generally pack together in a non-uniform fashion, with ordered or crystalline-like regions mixed together with disordered or amorphous domains. In some cases the entire solid may be amorphous, composed entirely of coiled and tangled macromolecular chains. Crystallinity occurs when linear polymer chains are structurally oriented in a uniform three-dimensional matrix. In the diagram on the right, crystalline domains are colored blue. Increased crystallinity is associated with an increase in rigidity, tensile strength and opacity (due to light scattering). Amorphous polymers are usually less rigid, weaker and more easily deformed. They are often transparent. Three factors that influence the degree of crystallinity are: i) Chain length ii) Chain branching iii) Interchain bonding The importance of the first two factors is nicely illustrated by the differences between LDPE and HDPE. As noted earlier, HDPE is composed of very long unbranched hydrocarbon chains. These pack together easily in crystalline domains that alternate with amorphous segments, and the resulting material, while relatively strong and stiff, retains a degree of flexibility. In contrast, LDPE is composed of smaller and more highly branched chains which do not easily adopt crystalline structures. This material is therefore softer, weaker, less dense and more easily deformed than HDPE. As a rule, mechanical properties such as ductility, tensile strength, and hardness rise and eventually level off with increasing chain length. The nature of cellulose supports the above analysis and demonstrates the importance of the third factor (iii). To begin with, cellulose chains easily adopt a stable rod-like conformation. These molecules align themselves side by side into fibers that are stabilized by inter-chain hydrogen bonding between the three hydroxyl groups on each monomer unit. Consequently, crystallinity is high and the cellulose molecules do not move or slip relative to each other. The high concentration of hydroxyl groups also accounts for the facile absorption of water that is characteristic of cotton. Natural rubber is a completely amorphous polymer. Unfortunately, the potentially useful properties of raw latex rubber are limited by temperature dependence; however, these properties can be modified by chemical change. The cis-double bonds in the hydrocarbon chain provide planar segments that stiffen, but do not straighten the chain. If these rigid segments are completely removed by hydrogenation (H2 Pt catalyst), the chains lose all constrainment, and the product is a low melting paraffin-like semisolid of little value. If instead, the chains of rubber molecules are slightly cross-linked by sulfur atoms, a process called vulcanization which was discovered by Charles Goodyear in 1839, the desirable elastomeric properties of rubber are substantially improved. At 2 to 3% crosslinking a useful soft rubber, that no longer suffers stickiness and brittleness problems on heating and cooling, is obtained. At 25 to 35% crosslinking a rigid hard rubber product is formed. The following illust ration shows a cross-linked section of amorphous rubber. By clicking on the diagram it will change to a display of the corresponding stretched section. The more highly-ordered chains in the stretched conformation are entropically unstable and return to their original coiled state when allowed to relax (click a second time). On heating or cooling most polymers undergo thermal transitions that provide insight into their morphology. These are defined as the melt transition, Tm , and the glass transition, Tg . Tm is the temperature at which crystalline domains lose their structure, or melt. As crystallinity increases, so does Tm. Tg is the temperature below which amorphous domains lose the structural mobility of the polymer chains and become rigid glasses. Tg often depends on the history of the sample, particularly previous heat treatment, mechanical manipulation and annealing. It is sometimes interpreted as the temperature above which significant portions of polymer chains are able to slide past each other in response to an applied force. The introduction of relatively large and stiff substituents (such as benzene rings) will interfere with this chain movement, thus increasing Tg (note polystyrene below). The introduction of small molecular compounds called plasticizers into the polymer matrix increases the interchain spacing, allowing chain movement at lower temperatures. with a resulting decrease in Tg. The outgassing of plasticizers used to modify interior plastic components of automobiles produces the new-car smell to which we are accustomed. Tm and Tg values for some common addition polymers are listed below. Note that cellulose has neither a Tm nor a Tg. Polymer LDPE HDPE PP PVC PS PAN PTFE PMMA Rubber Tm ( °C) 110 130 175 180 175 >200 330 180 30 Tg ( °C) _110 _100 _10 80 90 95 _110 105 _70 Rubber is a member of an important group of polymers called elastomers. Elastomers are amorphous polymers that have the ability to stretch and then return to their original shape at temperatures above Tg. This property is important in applications such as gaskets and O-rings, so the development of synthetic elastomers that can function under harsh or demanding conditions remains a practical goal. At temperatures below Tg elastomers become rigid glassy solids and lose all elasticity. A tragic example of this caused the space shuttle Challenger disaster. The heat and chemical resistant O-rings used to seal sections of the solid booster rockets had an unfortunately high Tg near 0  °C. The unexpectedly low temperatures on the morning of the launch were below this Tg, allowing hot rocket gases to escape the seals. Copolymers The synthesis of macromolecules composed of more than one monomeric repeating unit has been explored as a means of controlling the properties of the resulting material. In this respect, it is useful to distinguish several ways in which different monomeric units might be incorporated in a polymeric molecule. The following examples refer to a two component system, in which one monomer is designated A and the other B. Statistical Copolymers Also called random copolymers. Here the monomeric units are distributed randomly, and sometimes unevenly, in the polymer chain: ~ABBAAABAABBBABAABA~. Alternating Copolymers Here the monomeric units are distributed in a regular alternating fashion, with nearly equimolar amounts of each in the chain: ~ABABABABABABABAB~. Block Copolymers Instead of a mixed distribution of monomeric units, a long sequence or block of one monomer is joined to a block of the second monomer: ~AAAAA-BBBBBBB~AAAAAAA~BBB~. Graft Copolymers As the name suggests, side chains of a given monomer are attached to the main chain of the second monomer: ~AAAAAAA(BBBBBBB~)AAAAAAA(BBBB~)AAA~. 1. Addition Copolymerization Most direct copolymerizations of equimolar mixtures of different monomers give statistical copolymers, or if one monomer is much more reactive a nearly homopolymer of that monomer. The copolymerization of styrene with methyl methacrylate, for example, proceeds differently depending on the mechanism. Radical polymerization gives a statistical copolymer. However, the product of cationic polymerization is largely polystyrene, and anionic polymerization favors formation of poly(methyl methacrylate). In cases where the relative reactivities are different, the copolymer composition can sometimes be controlled by continuous introduction of a biased mixture of monomers into the reaction. Formation of alternating copolymers is favored when the monomers have different polar substituents (e.g. one electron withdrawing and the other electron donating), and both have similar reactivities toward radicals. For example, styrene and acrylonitrile copolymerize in a largely alternating fashion.

For polyisobutylene at a glance, click here! Polyisobutylene is a synthetic rubber, or elastomer. Its special because its the only rubber thats gas impermeable, that is, its the only rubber that can hold air for long periods of time. You may have noticed that balloons will go flat after a few days. This is because they are made of polyisoprene, which is not gas impermeable. Because polyisobutylene will hold air, it is used to make things like the inner liner of tires, and the inner liners of basketballs. Polyisobutylene, sometimes called butyl rubber, and other times PIB, is a vinyl polymer. Its very similar to polyethylene and polypropylene in structure, except that every other carbon is substituted with two methyl groups. It is made from the monomer isobutylene, by cationic vinyl polymerization. And this is that monomer isobutylene: Usually, a small amount of isoprene is added to the isobutylene. The polymerization is carried out at a right frosty -100 oC, or -148 oF for you Americans out there. This is because the reaction is so fast we cant control it unless we freeze it colder than a brass toilet seat in the Yukon. Polyisobutylene was first developed during the early 1940s. At that time, the most widely used rubber was natural rubber, polyisoprene. Polyisoprene was an excellent elastomer, and easy to isolate from the sap of the hevea tree. Huge plantations thrived in Malaysia and grew hevea trees to supply the worlds rubber needs. There was only one slight problem, and that was that Malaysia had just been conquered by the Imperial Japanese Army, and wouldnt you know we just so happened to be fighting the Second World War against them right at that moment. Before the war was over more than sixty million people would be dead. Deprived of natural rubber, the Allied nations did some quick thinking and came up with PIB. It obviously worked, because the Allies won the war. Ok, we didnt actually invent polyisobutylene during the war. It had been invented long before the war by chemists in Germany. Theres irony! But it wasnt very useful until American chemists came up with a way to crosslink it. What they did was to copolymerize isobutylene with a little bit, say, around one percent, isoprene. This is isoprene: When isoprene is polymerized with the isobutylene we get a polymer that looks like this: About one or two out of every hundred repeat units is an isoprene unit, shown in blue. These have double bonds, which means the polymer can be crosslinked byvulcanization just like natural rubber. What is this vulcanization? To find out, click here. Stealing Vulcans Fire There was a time long past when the only rubber we had was natural rubber latex, polyisoprene. Straight out of the tree, natural rubber latex isnt good for much. It gets runny and sticky when it gets warm, and it gets hard and brittle when its cold. Tires made out of it wouldnt be much good unless one lived in some happy land where the temperature was seventy degrees year round. A long time agohow long, you ask? It was about a hundred and sixty years ago, 1839 to be exact. This was before there were any cars to need tires, but the idea of a useable rubber was still attractive. One person trying to make rubber more useful was named Charles Goodyear, a tinkerer and inventor, and by no means a successful one at this point.

Personal Narrative - Race :: Personal Narrative Essays

Personal Narrative- Race Wait. Be still. Don't go over the line. Don't let go. Wait for it. "BANG!" My reactions were precise as I sprung out of the blocks. The sun was beating down on my back as my feet clawed at the blistering, red turf. With every step I took, my toes sunk into the squishy, foul smelling surface, as my lungs grasped for air. Everything felt the way it should as I plunged toward my destination. I clutched the baton in my sweaty palms, promising myself not to let go. My long legs moved me as fast as I could go as I hugged the corner of the line like a little girl hugging her favorite teddy bear. The steps were just like I had practiced. As I came closer to my final steps, my stomach started twisting and my heart beat began to rise. The different colors of arrows started to pass under my feet, and I knew it was time. "Reach," I yelled to Susan, whom had seemed unusually far away. Yelling, "Slow down, slow down," turned into "Stop!" Susan halted to a stop as the gold baton fell into her hands and she took off into a dead sprint. The devil colored flag rose. We were disqualified from something that we all dreaded; going out of the exchange zone. I had never really been a part of a team that had a chance to win something, but the potential was always there. I finally got my chance to be a part of such a team my sophomore year of track. Mr. Jones, the head track coach, had decided to experiment with some different races to gain more team points. Since the girls' team lacked a medley relay, he placed Cindy, Kim, Susan and I in those spots. Cindy would run the 400, Kim would run the 200, and Susan and I would start the race off by each running the 100. We all had worked viciously to earn those spots by running off against our teammates. Going into the first race we had not expected much since Susan and I had never run this type of race. There were so many crucial things that we had to remember. It wasn't just to get out of the blocks and burn up the track; there was a baton involved, a certain amount of steps to take, and even a certain way to hold the baton.

History :: essays research papers

In my paper the Democratic Candidates are Al Gore and Bill Bradley. They both have a lot of the same views on issues that have come out in the campaigning. For the Rebublicans it is George W. Bush and John McCain. Both of these guys have different views on their issues. The debates between these two men have really been heating up and it will be interesting to see the outcome of this election. But also on the other side of this the Democratic battle has also been a though one but I think Bradley will drop out. He feels and knows he is over matched. Al Gore served in the U.S. Army in Vietnam. He worked for seven years as a newspaper reporter and then was elected to Congress from Tennessee. After eight years in the House of Representatives and eight years as an U.S. Senator from Tennessee, he was elected Vice President of the United States.   Ã‚  Ã‚  Ã‚  Ã‚  For almost seven years, Al Gore has been a central member of President Clinton's economic team -- helping to design the program that has led to our strong economy, casting the tie-breaking Senate vote for the plan in 1993, helping to pass the first balanced budget in 30 years. He has helped to usher in the longest peacetime economic expansion in American history -- with over 18 million new jobs, wages rising twice the rate of inflation, the lowest African-American and Hispanic poverty on record, the highest level of private home ownership ever, more investment in our cities, and the lowest unemployment in 29 years.   Ã‚  Ã‚  Ã‚  Ã‚  Since his days in the House and Senate, Vice President Gore's environmental record has been unparalleled. He leads the Administration's efforts to protect the environment in a way that also strengthens the economy -- such as working with the Big Three auto makers to support the development of a new generation of fuel- and energy-efficient vehicles, and working to combat global warming in a way that also creates new jobs, by helping America lead the estimated $400 billion worldwide market for new technologies that clean up the environment.   Ã‚  Ã‚  Ã‚  Ã‚  Bill Bradley was born on July 28, 1943, in Crystal City, Missouri, the only child of Warren and Susan Bradley. The Bradleys lived a comfortable, middle-class life in a small, multiracial, multiethnic town on the banks of the Mississippi River, thirty-six miles south of St. Louis. The Crystal City of Bill's youth was a blue-collar company town with a single stoplight and a population of 3,492. With the support of his family and the close-knit community around him,

Physician And Managed Care Contracts Essay

A contract is a legal binding agreement between two parties that is aimed to execute a certain objective. It is a kind of arrangement wherein a certain action is pledged in exchange for a specific proposition or offer. In order for a contract to be valid, four essential elements must be present in a contract. Firstly, two parties should exist in the contract. One party is presenting an offer while the other party is accepting the offer as a form of return for whatever specifications are requested in the contract. Secondly, the contract should indicate that both parties give their consent or are willing to enter into such an arrangement. Such intention should show that the person giving the offer is capable of providing the offer, while the party accepting the offer should be able to clearly show his/her acceptance of the offer. In addition, both parties must be willing to enter an agreement without any other hidden conditions. Thirdly, a purpose or objective should be indicated in a contract. The purpose should be detailed enough to clearly show what is requested or expected in exchange for the specific offer. And lastly, adequate consideration or an adequate value must be indicated as offer in the contract, in the form of money or in kind. The consideration or compensation can not be given to the accepting party prior to the acceptance of the offer. The act of accepting an offer constitutes a deal. Certain offers have a limited time of availability, wherein an expiration date is indicated and the offer can not be accepted after the said date, unless the offer is renewed or stands indefinitely. In addition, the party presenting the offer has the right to withdraw its offer, but only before an acceptance is received. Once an offer is accepted, the contract may not be modified or revised. Changes in the offer may only be incorporated during the negotiation stage of the agreement, which then makes a contract some kind of a bargain. Similarly, physicians enter contracts with managed care organizations (MCOs) or health management organizations (HMOs) in order to promote their services. The four essential elements of a contract should be carefully studied before accepting any offer or signing any contract. For example, as for the element of willingness and capability to enter a contract, a physician should initially must find out the MCO/HMO’s length of operation and financial stability, because this will give the physician an idea whether the company is capable to pay him at a regular schedule. In addition, it would be good to contact some colleagues who have signed contracts with the same company, in order to determine the strengths and weaknesses of the organization and to unearth any unwritten conditions or policies. The physician should also investigate the identity of the MCO/HMO, and any other parties in the contract, should there be more than two parties indicated in the contract. The most overlooked element of a contract between a physician and an MCO/HMO is the purpose or objective of the contract, which describes a several definitions of services and people that will be covered by the health plan, both during emergency and out-patient consultation events. A comprehensive study of the contract may possibly prevent misunderstandings between the two parties and therefore provide a clear-cut description of the services that the physician is expected to deliver. Another important element of a physician-MCO/HMO contract is the obligations of each party. It is usually indicated in the contract that the physician will actively maintain his/her medical practice documents such as licenses, certifications, registrations and permits in order to provide his/her services to patients. The physician should also inform the MCO/HMO of any modifications on his/her status as a practicing physician. In turn, the MCO/HMO presents its rules and regulations to the potential physician or health care provider working under their company. All policies, guidelines, reviews and appeals should be revealed in order to have its physicians working at the standardized efficiency and competency. The physician’s compensation should be indicated in a physician-MCO/HMO contract. Details including the amount and schedule of payment should be clearly stated in the contract. Payment modes may be in form of per diem, per case, per service or a certain percentage of the premiums. The physician, in turn, should understand the protocol for filing claims and any other arrangements or coordination with the MCO/HMO, including the limited time when these documents may be filed. The MCO/HMO should also indicate in the contract that the physician will receive his/her salary on a regular basis. A physician-MCO/HMO contract may be terminated by either mutual agreement of both parties, or with sufficient cause or reason from the physician, or without cause or reason from the physician. However, a 30-day notice is usually required before any termination takes effect, to provide ample time for the physician to finalize any current patients, cases, services and/or referrals. Contracts are legally binding documents which must be carefully studied and considered before pursuing an agreement and letting the contract take full effect. Every contract has its specific details and all sections of the contract should be well understood and explained.

Osama Bin Laden Research Paper

Osama Bal Laden; the mastermind of 9/11 Christian Hanker December 21 , 2012 World History Period 1 Osama Bin Laden changed the world on September 1 1, 2012, when he orchestrated the 911 1 bombings on the world Trade center in New York City. He has also formulated many other attacks including the October 2000 attack on the US Cole, and attacks on the US embassies in Nairobi, Kenya, and Dark sees Salaam, Tanzania in 1998 (Encyclopedia of World 1).Osama Bin Laden had a negative Influence on societies, economies, and religion throughout the world because of his actions in masterminding many radical terrorist attacks, and because he created and ended al-Qaeda. Osama Bin Laden had a dramatic effect not only on the society of the United States but also worldwide. These radical attacks have resulted in changes to the way society conducts business, travel, Immigration, and most Importantly, how people view and trust each other. Simply put, it has in many ways resulted in a drastic change to m any people's behavior.The attacks of 9/1 1 resulted in increased security exponentially. After these attacks, airport security was amplified. Other security measures were Implemented such as every time someone flies they are required to undergo body scanning; they have to remove shoes and belts, and all liquids over three point four ounces must be packed in checked luggage Monsoon 13). All these measures are now enforced to ensure maximum safety and security in airports. Instead of being able to breeze through the airport and board their flight, people are required to be there two hours early. Which has become a necessary inconvenience and a time consuming practice. After the 9/11 attacks, people were very hesitant to fly because they were afraid. To help ease the anxiety of flying and perform the safety sys precautions, the Nun deed t States created the Transportation Security Administration. The TTS hired over 50,000 people to work in airports across the country and have found to date over fifty million prohibited items, 5,000 of them being firearms Monsoon 7-10). Since Osama Bin Alden's various attacks, some airlines like Canada 3000 and Swiss Air were on the verge of going bankrupt.To counteract this, the airlines crammed more seats in their airplanes, cut the complimentary food service, and reduced flights Monsoon 22). This inconveniences the passengers because there s less space and comfort on board and with less flights, not everyone may get a seat on their flight. Osama Bin Laden had a direct impact on the way we travel, has put anxiety in the minds of innocent people wanting or needing to travel on an airplane, and caused changes in the way commercial airlines conduct businesses.Osama Bin Laden has affected society worldwide through the lives lost in 9/1 1 and America's war on terrorism. Osama Bin Laden was responsible for the many deaths that occurred as a result of his terrorist attacks. In the wake of 9/1 1, approximately 3000 people died (Newspape rs 1). This not only affected the people that died, but also the people that love them, witnessed their death, their neighbors, the community around them, and also the world. An enormous amount of grief was felt throughout the world and many societies were humbled.Another way Osama Bin Laden has impacted society is the number of troops, particularly American, that have been sent to Afghanistan and Iraq to fight in the war on terrorism. Approximately 70,000 troops were sent to Iraq and Afghanistan (Encyclopedia of World 23). This affected both their own lives and also their loved ones, not knowing if they are alive, outing a great amount of fear in millions of people's lives worldwide. The cost of the war on terrorism has not only been human lives.Governments across the world have had to fund the increased deployments and make revisions in their budgets for the future. Finally, there has been a large death toll incurred by innocent Muslims living in both America and on the battlefiel d. In retaliation to the 9/11 bombings, many Americans discriminated against Muslim Americans and many cases resulted in violence. Muslim lives have been lost fighting for AY-Qaeda and innocent civilians eave died, being caught in the middle of this war. Osama Bin Laden is responsible for changing society and the lives of many Americans, troops and his own followers.Osama Bin Laden left his mark on society by his role in inflicting terror into the hearts and minds of people worldwide. What is so frightening about terrorism is that it could happen anywhere and anytime. Bin Laden used this advantage of mystery to plant the seed of fear into people's minds worldwide. In October 2001, according to a Gallup poll, forty six percent of Americans said terrorism was America's biggest problem (Grief 47). This shows that Osama Bin Laden has had an enormous and lasting influence on the way Americans think and why they may do certain things.Osama Bin Laden had such a great influence on Americans and their minds that the CIA released a bounty worth $25 million for Bin Laden. New York City authorities put posters up around New York City showing again how much the capture of Osama Bin Laden was worth to America and how much he had affected society. This is evidenced in figure one, showing that officials want Bin Laden dead or alive. Osama Bin Laden destroyed billions of people's peace of mind worldwide. The 9/1 1 attacks were carried out in conditions of everyday life, which was in essence using the element to surprise as a weapon.What is more terrifying is that he managed to install his people into our communities. These terrorists lived amongst us until Osama Bin Laden gave his orders. This effectively created a feeling of mistrust and paranoia after the 9/1 1 attacks. It certainly had a great impact on the state of mind of many Americans. Osama Bin Laden impacted society by influencing the modification of the security systems, being responsible for killing thousands of peo ple, and outing terror in millions of people's minds worldwide.While Osama Bin Laden had an extraordinary influence on how people around the world feel and behave he also had a negative impact on America's economy. One way Bin Laden left his mark on the United States economy is that his actions caused the United States to spend billions of dollars for the military, defense, and security sectors. In the years of 2006-2008, military spending increased by $540 million to supply weapons and transportation to fight the war on terror and to deploy troops into Pakistan and Afghanistan to find Bin Laden (Griffin 17).This huge expense would not have been incurred if Bin Laden had not executed the attack on the World Trade Centre. These funds could have been spent on other things, like paying off the national debt or providing better education and healthcare for American citizens. Not only did Bin Laden cause the United States spend unnecessary money on finding him, but he also affected socie ty by redistributing $540 million of potential funding which could have been used in improvements in society. This money was spent on defense and the security sectors.All three of these divisions boosted the United States debt to $14. Trillion (Burger 8). Osama Bin Laden cost the United States lots of resources, money, and time in the search for their peace of mind. Osama Bin Alden's actions have caused friction amongst Middle Eastern and western countries, raising the prices of odds from these nations, in particular oil. After the 9/1 1 attacks, the unhealthy relationship between Islamic countries and America made Muslims reluctant to trade, resulting in an increase in the oil price. Before 9/1 1, oil prices were $1. 3, per gallon but they have increased to a current price of $3. 65 per gallon (Mille 16). Obviously, with the price of gas skyrocketing by over $2 after 9/1 1, resources have become very expensive to obtain and has put many Americans in difficulties financially because it is a huge increase that has to be accounted for. Other resources such as gold have experienced price increases. At the time of the 9/1 1 bombings, gold was priced at $271. 5 per ounce however it is now very expensive, rising to $1821 per ounce (Mille 13-14).The price of gold after 9/11 has risen over 600%, while the American dollar has lost one third of its value. Since the 9/1 1 attacks, he increased price of many plentiful goods within the Middle East has made it more difficult for people to pay for them. Another way Bin Laden affected The United State's economy is due to his role in planning the destruction caused which resulted in the reparations the insurance companies owed, and the time and money spent cleaning the devastation.Firstly, in the attacks that killed over 3,000 people, it cost an estimated $1. 5 billion to clear the devastation where the World Trade Centre stood (Gaffing 13). This cost in clearing the remains, moving it and disposing of it was a large expense w hich otherwise would have been used on other necessary expenditure such as education or roads. These funds were spent on an event that could not have been predicted or budgeted for. The cost to America can also be accounted in for the time to thousands to workers and the tort to volunteers.Another way this incident affected the economy is in the insurance claims that were owed to millions of people. These insurance claims include life insurance, auto insurance, and property insurance. The combination of lives lost and damage of properties led to and estimated $40 billion price tag in insurance claims (Gaffing 7). This huge toll on insurance companies made many companies bankrupt, and if not bankrupt, premiums became very expensive for people wanting to purchase insurance.The cost of disposing and clearing the site where the World Trade Centre stood and the insurance claims incurred after the attack crippled the economy, especially that of New York City. After the attacks of 9/1 1, m any other struggles within the United States economy arose. One example of this is that the unemployment rate in the United States almost doubled. Prior to 9/1 1, the unemployment rate was four point nine percent but soon after, the unemployment rate rose to nine point one percent Mille 7-8).As a result of the terrorist attacks over 600,000 Jobs were lost, 226,000 of them in the travel industry (Mille 7-8). This huge cut of workers left many people struggling to survive, becoming homeless, and relying on welfare or other sorts of government aide to survive. With a large demand for supplies to aid homeless people, this increased the United States debt even further, setting the debt deeper by the millions. Thousands of small businesses were destroyed by the wreckage in New York City, from the collapse of the World Trade Centre and financially.Approximately 18,000 small businesses in lower Manhattan, particularly around the site of World Trade Centre, were either physically destroyed b y flying debris or financially crushed without income to offset the costs to repair their shops (Gaffing 8). These small businesses were particularly hurt because they did not have large cash reserves or other stores to make sure they were earning money. Instead, they were out of business for six weeks while repairs were being made in lower Manhattan.This lead to the large amount of unemployment that occurred and also left many people bankrupt. The attacks of 9/1 1 that Osama Bin Laden formulated had a demoralizing toll on America's economy by increasing unemployment, destroying small businesses, skyrocketing the prices of goods and forcing America to pay hundreds of thousands of dollars to ensure safety and to find the man behind all the chaos and devastation. Osama Bin Laden was a very influential person and he used his power to change his religion for the worse.One way that he did this is that he encouraged a violent form of Islam called Salamis. With his extreme wealth, inheriti ng $300 million at age thirteen when his father died (Encyclopedia of World 4), ND power, he has influenced millions of Muslims to adopt his ideas and beliefs that encouraged violence. In Osama Bin Laden â€Å"Jihad against Jews and Crusaders†, Osama Bin Laden encourages Muslims worldwide that it is their duty religiously to kill all Americans and their allies whenever possible (bin laden, Osama).Bin Laden promoted a very extremist form of Islam and was able to spread it throughout the Muslim world. He proposed to kill other people because they were of a different religion and belief, even though they may be innocent of any religious hate crimes. He executed these attacks in many different ways, including bombings, assassinations, and cyber attacks (AY Qaeda 2). This added to his repertoire as being very dangerous and helped his followers strive for their mission of the Jihad.He was very intolerant to other religions and wanted others to tallow in his pate Laden changed views about religion and religious tolerance worldwide by increasing the stereotypes towards Middle Eastern or Islamic people being terrorists. Many forms of violence against Muslims or people with dark skin and dark hair occurred after 9/1 1 in retaliation for the attack. Osama Bin Laden therefore negatively affected religion, because innocent Muslims are being discriminated against because of Bin Laden attacks. Osama Bin Laden had a huge negative influence on religion, the economy, and society worldwide.
