Dante Inferno (by Anthony Esolen) Essay Example | Topics and Well Written Essays - 1250 words

Dante Inferno (by Anthony Esolen) - Essay Example Hence, it is interesting to ask the question, â€Å"If Dante had written the Inferno today, who would he have placed as sinners in the different rings of hell?† Who would qualify, indeed? If there was anyone who epitomized lust, it is Hugh Hefner. As the founder of Playboy Magazine, Hefner bragged that â€Å"I have slept with thousands of women, and they all still like me† (Hylton, â€Å"What Ive Learned: Hugh Hefner†). Indeed, being someone who was able to—and at 83 years old still able to—get scores of famous and sexy women to pose nude for a magazine, to expose everything that they have kept hidden and to go to bed with him, with multiple partners at the same time, Hefner is someone who can be expected to appear in the second circle of hell—if it is made a reality. Hefner believes that â€Å"Sex is the driving force on the planet. We should embrace it, not see it as the enemy† (Hylton, â€Å"What Ive Learned: Hugh Hefner†). And he made people believe in this too, with Playboy being one, if not the, of the most popular magazines that caters to men’s sexual fantasies and fetishes. Not only has he lived the life of a lustful, but he has also encouraged others to follow suit. He even admitted the fact that he masturbates when he is alone, although, he says that this rarely ever happens (Hylton, â€Å"What Ive Learned: Hugh Hefner†). The fact that he admitted this even makes masturbation sound cool as it is coming from Hugh Hefner, who is idolized by a multitude of men. It can undeniably be said that Hefner is someone who is a slave to his desires and to carnal pleasure. Indeed, he is a â€Å"carnal malefactor† to the very core of his being. And thus, it is undoubtedly appropriate for him to be flogged by a violent storm, together with the rest of the lustful. â€Å"The infernal hurricane that never rests; Hurtles the spirits onward in its rapine; Whirling them round, and smiting,

Evaluating the performance of tesco plc

Evaluating the performance of tesco plc For this assignment, I ideally considered an organization TESCO. It is a largest supermarket chain in United Kingdom. It employed over 260,000 employees over 1,800 stores. Since its having ample of people, managing human resource would be a great challenge to such company. Therefore I think this is most suitable to go through my study. Jack Cohen founded Tesco in 1919 when he began to sell surplus groceries from a stall in the East End of London. The Tesco brand first appeared in 1924. The name came about after Jack Cohen bought a shipment of tea from T.E. Stockwell. He made new labels using the first three letters of the suppliers name (TES), and the first two letters of his surname (CO), forming the word TESCO. The first Tesco store was opened in 1929 in Burnt Oak, Edgware, and Middlesex. Tesco floated on the London Stock Exchange in 1947 as Tesco Stores (Holdings) Limited. The first self service store opened in St Albans in 1951 (still operational in 2008 as a Metro), and the first supermarket in Maldon in 1956. During the 1950s and the 1960s Tesco grew organically, but also through acquisitions until it owned more than 800 stores. The company purchased 70 Williamsons stores (1957), 200 Harrow Stores outlets (1959), 212 Irwins stores (1960), 97 Charles Phillips stores (1964) and the Victor Value chain (1968) (sold to Bejam in 1986). Founder Jack Cohen was an enthusiastic advocate of trading stamps as an inducement for shoppers to patronise his stores. He signed up with Green Shield Stamps in 1963, and became one of the companys largest clients. Now there are more than 1800 stores running under Tesco. Tesco is being a one of the most important share holder in UK share market UK market share Graph Showing Market Share of Tesco According to TNS World panel, Tescos share of the UK grocery market in the 12 weeks to 10 August 2008 was 31.6%, up 0.3% on 12 weeks to 13 July 2008. The business market share has been rising monthly since its recent low of 30.9% in March 2008. Across all categories, over  £1 in every  £7 (14.3%) of UK retail sales is spent at Tesco. Tesco also operates overseas, and non-UK revenue for the year to 24 February 2007 was up 18% on 25 February 2006. Supermarket Consumer Spend ( £000s) Market Share August 2008 +/- from July 2008 Tesco 6,351,531 31.6% à ¢- ²0.3% Asda 3,410,431 17.0% à ¢- ²0.1% Sainsburys 3,175,543 15.9% à ¢- ²0.1% Morrisons 2,233,137 11.1% à ¢- ¼0.2% The Differing Perspectives of Human Resource Management Today Human Resource Management, which is a very significant functional field of organizational management, has evolved a very board and profound management branch. HRM is the efficient and effective utilization of human resource to achieve goals of an organization. While other resources make things possible only human resource make things happen. As employees have different personalities, different expectation and different abilities, it is difficult to manage them. In fact, HRM is a strategic source of competitive advantage that is more sustainable. Guests Model According to the David Guests (1989-1997) model of HRM has 6 dimensions of analysis: HRM strategy HRM practices HRM outcomes Behaviour outcomes Performance outcomes Financial outcomes The model is prescriptive in the sense that it is based on the assumption that HRM is distinctively different from traditional personnel management. A business can take to HRM many different approaches. Guest(1999) identified two different perspectives of HRM soft and hard, also these perspectives are similar to the tight and loose perspectives which are identified by Handy. According to the soft view of HRM, it explains employees to be a valuable asset to the company. (e.g., it is people that make the difference; the workforce is the most vital asset; human resources are the sole, real, sustainable, competitive advantage or edge.) On the other hand, the hard view of HRM considers that employees are resources to be managed effectively to achieve business objectives. According to Truss, those soft and hard approaches are based on opposing aims. The aim of soft model is to improve the competitive advantage of the company and the individual development of the employee based on the assumption that employees are viewed as a resource working to be trained and developed. In contrast, on the hard model employees are viewed as a cost that has to be managed and the aim of the model is to use the employees to achieve the organization goals. These approaches can also be viewed as tight and loose HRM, which are system based on compliance and commitment. Storeys Definitions The different perspectives can also be seen between the difference of personnel and HRM. Storey (1992) regarded HRM as a set of interrelated policies with an ideal HRM consisting of beliefs an assumption; strategic aspects; line management; key levers and dimension. For those who recognize a difference between personnel management and human resources, the difference can be described as philosophical. Personnel management is more administrative in nature, dealing with payroll, complying with employment law, and handling related tasks. Human resources, on the other hand, are responsible for managing a workforce as one of the primary resources that contributes to the success of an organization. Then, human resources are described as much broader in scope than personnel management. Personnel management is often considered an independent function of an organization. Human resource management, on the other hand, tends to be an integral part of overall company function. Personnel management is typically the sole responsibility of an organizations personnel department. With human resources, all of an organizations managers are often involved in some manner, and a chief goal may be to have managers of various departments develop the skills necessary to handle personnel-related tasks. While HRM concerns the human side of the management of enterprises and employees relations with their firms, Industrial Relations (IR) is comprised of certain actors, certain contexts, and ideology which binds the industrial relation system together and a body of rules created to govern the actors at the work place and work community. This term is a broader concept when compared with labour relations and it is concerned with the systems, rules and procedure used to determine the reward for effort and other conditions of employment. It can be viewed from tripartite perspective. Though the term IR seems to have a more macro view rather than micro view, it can be viewed as a one of the fields of HRM. Therefore we discuss IR under the theme of HRM. Several view points of HRM HRM is the management of people at work in an organization. Human resources are unique as they have expectation characteristics which are missing from all other resources. They have to be managed legally and ethically. Unilever practice this correctly. In management approach, HRM is a responsibility of every manager irrespective of his/her fields of interest a specialization. Though the Unilever has a human resource department led by a human resource manager, it has to serve all managers, non-managers and departments through it expertise. Also HRM is viewed as a system of interrelated functions. For instance job analysis affects recruitment, selection and pay management. When human resource activities are involved as a whole, they from the Unilevers human resource management system. Also HRM is an open system that is affected by the external environment that is composed of various forces which have direct or indirect influences on the organization and its HRM. In case of Unilever, those forces, labour law, trade unions, education system, training system, employee marketsetc affect HRM. Strategic approach to HRM is a recent development in the disciplines of HRM. HRM is called strategic HRM from this view point and the purpose is to generate or enhance competitive advantage or support achievement of strategic business needs. When it comes to Unilever, there also HRM is fully integrated with the strategy and strategic needs of the Unilever. Also HRM can be viewed from the proactive approach. Being proactive means acting before a problem occurred. Since there may be situations where problems arise suddenly and no time is available to anticipate, Unilever also recommended proactive HRM to follow whenever it is possible. Strategic Human Resource Management (SHRM) is treated a resent development in the field of HRM. It is concerned with those decisions which have a major and long term effect on the employment and development of people in the organization and on the relationship which exist between its management and staff. It is perceived and believed as an advance topic. The purpose of strategic approach to HRM is to generate or enhance competitive advantage or support achievement of strategic business needs and goals. Strategic aspect of HRM has four features which are as follows: HRM is a broad approach to managing people at work based on philosophy of HR. HRM is a major source of competitive advantage. It links to competitive advantage of the organization significantly. HRM policies/functions cohere within themselves and with other functional fields of organizational management. HRM is fully integrated with the strategy and strategic needs of the organization. Also HRM plays an important role in Unilever strategic management. HRM contributes to strategy formulation, strategy implementation and strategy evaluation. Flexibility within the Workplace Flexibility in work is an important key to a company, if the company need employee attraction and not to lose them. Flexibility means the way of working, which means that flexibility can be based on time and location. The flexibility in work can be categorized as follows; Part-Time Workers Part time workers are cheaper to recruit and they are not permanent and cannot involve in management procedures. The rights of part time workers are limited. Fixed/Short-Term Contract Workers Workers who are taken at a specified period as the company need. Outside Contractors/ Sub Contractors Group of workers or individual worker requites from outside the company for a special work at a specific time. Self Employed labour People who work for an exact company as a self employed basis. Agencies An agency which supplies employees to companies which seeks for labour. Get the customer to do the work Without any employee customers fulfil his needs by himself by use of technology. Shift working A continue way of working where employees work according to a time based system. Flex-Time A way of making decision by employee about his working time with in a core time. Job Share A way of sharing once works with other who work full time job on a part time basis. Annualized Hours A number of hours labour is given to employee and he need to complete that within a year. Tele working An easy way of working, by the use of technology employee can work at his own place, home, or even at road. Hot Disking/Hotel ling Employees need to go outside the company for specific job and they have a specific desk for them self in the office for permanently. Home working This is the same as Tele working and work can be carried out in home and this no need of network or communication As shown above flexibility of work can achieve the company a high standard in business and the satisfaction of the employee will be high because they get what they need. The flexibility in work will give advantage as well as disadvantages. Some of them are as follow. Employer view Employee satisfaction will reduce employee strikes etc. High level of outcome can be achieve Cost of employee is low Sometime cost cannot be maintained Employee internal competition will effect on company manufacture process or sales can be continue without a stop. Employee view Employee satisfaction is high Working stress is low There will be a new can do attitude in the business Time can be managed to do personal works Employers will miss use the labour Sometimes salary payment will be postponed. At Tesco, they are giving employees (and not just the women) the chance to work flexibly for years. Flexible working can mean Working part-time, Working from home Job sharing Most who take up the opportunity are parents. But not all One Tesco employee studied at college for his degree and was allowed to work flexibly in order to train more often. Another was given a sabbatical to practice with his rock band. These examples show how Tesco has given flexibility for their employees. When it comes to maternity and paternity packages, Tesco beats many other businesses. Company also believes in educating managers about the merits of employing mums. Work life initiative has been developed many years in response to employee request in Tesco. Tesco believes that this will make employee attraction on the company and the satisfaction will rise above the roof. Tesco sees the flexibility as an important issue because that directly effect on employees and without them company cannot carry out the works. Tesco as a company has arrange different ways of flexibility in work specially for mother who work full time, company has given them a holiday system where they can take holidays without a pre notice. The most of the part time worker in the company are employed in Europe rather than Asia. Form of the Discrimination Discrimination is someone is not treated as fairly to someone else in similar situation or treated differently because they are deferent in some way. Have two types of discriminations. Those are, Direct Discrimination Indirect Discrimination Direct Discrimination Race, sex, nationality of ethnic or national origin, disability are using for treat badly to someone. Indirect Discrimination Occurs when rules, regulations, policy procedures operating, which appears to treat everyone equality has the effect of the disadvantaging certain group and the recruitment is not reasonable. Current Legislations are against Employment Discrimination. There are 3 main legislations. Those are, Employment Equality (Age) Regulations 2006. Employment Equality (Religion or Bellies) Regulations 2003. Employment Equality (sexual orientation) Regulations 2003. Employment Equality (Age) Regulations 2006 Protect against discrimination on grounds of age in employment and training prohibits direct and indirect discrimination, victimization, harassment and instruction to discrimination.

Employment Equality (sexual orientation) Regulations 2003 The directive protects against discrimination of sexual orientation in employment, Vocational training, Promotions and Working conditions. Proposed Changes to the Law Hours, Rest break and maximum working hours of the week. Most workers have the maximum they should work set down in law under the working time regulations. That guide can get understand rest breaking and rest periods offer employers to workers. Give national minimum wage to employees. Give pension scheme to all workers and increase maximum working age limit. Range of current Initiatives and practices are which focus on equal Opportunities in Employment. Current initiatives are very helpful for build up employer and employee rights. It is very need to work with trade unions. Other hand it is very helpful for give equal opportunities to all employees. Bellow I mentioned some practices for focus on equal opportunities in employment. Opportunity 2000 is aim to increase the quality and quantity of woman employment opportunities both practice and public sector organizations. Codes of practices; there have some codes to practice law.eg: the pension regulators codes of practice guidelines on how to comply with legal requirements. Disable workers to give flexible works and more job opportunities. Compare and Contrast Equal Opportunities and Managing Diversity Equal Opportunities Concentration on discrimination /unfairness Perceived as an issue for woman and ethnic minorities and people with disabilities. Focus on boosting proportion of minority groups in employment. Strategy has to be main teamed. Emphasis on positive action rather than corporate vision. Managing Diversity Aims to ensure that all employees maximize their potential and contribution to the organization. Concentrates on movement within an organization it is culture and the meeting of business objectives. Concerns all staff and specially managers. Does not rely on positive action and provides a vision. (John P.Wilson workplace diversity and training 2005 page253) Tesco is view the Concept of Discrimination in Employment. Tesco protect their work force discrimination. They have suitable work patterns for employees. Every time they modify their rules and regulations for current social needs. In this time they are giving more job opportunities for female workers. They ignore race, ethnic, colour for recruitments and training promotions. Tesco have specific age limit for recruitments and pension. How is the organization move from equal opportunities to managing diversity? Tesco move from equal opportunities to managing diversity use some activities. Such as internal employee networks, Monitoring programs, Diversity conferences. They build up employee societies for discuss their problems and set solutions. Other hand trade unions are helping solve the employees problems. Management every time monitoring employees efficiency and give more benefits and promotions to them. Performance Management Armstrong and Baron define performance management as A process which contributes to the effective management of individuals and teams in order to achieve high levels of organizational performance. As such, it establishes shared understanding about what is to be achieved and an approach to leading and developing people which will ensure that it is achieved. They go on to stress that it is a strategy which relates to every activity of the organization set in the context of its human resource policies, culture, style and communications systems. The nature of the strategy depends on the organizational context and can vary from organization to organization. In other words performance management should be: Strategic it is about broader issues and longer-term goals Integrated it should link various aspects of the business, people management, and individuals and teams. It should incorporate: Performance Improvement throughout the organization, for individual, team and organizational effectiveness Development unless there is continuous development of individuals and teams, performance will not improve Managing Behaviour ensuring that individuals are encouraged to behave in a way that allows and fosters better working relationships. While most firms have a human resources or personnel department that develops and implements HRM practices, responsibility lies with both HR professionals and line managers. The interplay between managers and HR professionals leads to effective HRM practices. For example, consider performance appraisals. The success of a firms performance appraisal system depends on the ability of both parties to do their jobs correctly. HR professionals develop the system, while managers provide the actual performance evaluations. The nature of these roles varies from company to company, depending primarily on the size of the organization. This discussion assumes a large company with a sizable HRM department. However, in smaller companies without large HRM departments, line managers must assume an even larger role in effective HRM practices. HR professionals typically assume the following four areas of responsibility: establishing HRM policies and procedures, developing/choosing HRM methods, monitoring/evaluating HRM practices, and advising/assisting managers on HRM-related matters. HR professionals typically decide (subject to upper-management approval) what procedures to follow when implementing an HRM practice. For example, HR professionals may decide that the selection process should include having all candidates complete an application, take an employment test, and then be interviewed by a HR professional and line manager. HR professionals also consult with management on an array of HRM-related topics. They may assist by providing managers with formal training programs on topics like selection and the law, how to conduct an employment interview, how to appraise employee job performance, or how to effectively discipline employees. HR professionals also provide assistance by giving line managers advice about specific HRM-related concerns, such as how to deal with problem employees. Line managers direct employees day-to-day tasks. From an HRM perspective, line managers are mainly responsible for implementing HRM practices and providing HR professionals with necessary input for developing effective practices. Managers carry out many procedures and methods devised by HR professionals. For instance, line managers: Interview job applicants Provide orientation, coaching, and on-the-job training Provide and communicate job performance ratings Recommend salary increases Carry out disciplinary procedures Investigate accidents Settle grievance issues The development of HRM procedures and methods often requires input from line managers. For example, when conducting a job analysis, HR professionals often seek job information from managers and ask managers to review the final written product. Additionally, when HR professionals determine an organizations training needs, managers often suggest what types of training are needed and who, in particular, needs the training. Health and Safety at Tesco Occupational Health and Safety is an essential element of a successful and sustainable business  in todays global village.  Consequently, Tesco takes responsibility for  Occupational Health and  safety very seriously. Sustainable, profitable growth for Tesco is dependent on: Providing consumers and customers with products that are safe in use.   Protecting the health and safety of employees and contractors.   Managing activities so as to provide care and protection of the environment  Ã‚  Ã‚   To achieve a safe working environment and a world class reputation for Tesco in Health Safety at Work Some companies take some actions in order to retain health and safety in the company. Some may be in success but some companies cant achieve that goal. Tesco achieves health and safety by followings; Developing, designing, operating and maintaining facilities and processes that are safe and without risk to health. Developing, introducing and maintaining systems, which will establish appropriate standards of occupational health and safety and ensure compliance with all applicable legislation and internal Tesco standards by means of regular auditing? Setting annual improvement objectives, targets, and reviewing these to ensure they are being met at company, divisional and departmental levels to ensure continual improvement. Involving all employees in the preparation, review and implementation of this policy and providing appropriate training and safety awareness. Holding management at all levels accountable for the occupational health and safety performance of their staff. Recruitment Process at Tesco Recruitment refers to the process of screening, and selecting qualified people for a job at an organization or firm, or for a vacancy in a volunteer-based organization or community group. While generalist managers or administrators can undertake some components of the recruitment process, mid- and large-size organizations and companies often retain professional recruiters or outsource some of the process to recruitment agencies. External recruitment is the process of attracting and selecting employees from outside the organization. The recruitment industry has three main types of agencies: employment agencies, recruitment websites and job search engines, and headhunters for executive and professional recruitment. The stages in recruitment include sourcing candidates by advertising or other methods, and screening and selecting potential candidates using tests or interviews. The proper start to a recruitment effort is to perform a job analysis, to document the actual or intended requirement of the job to be performed. This information is captured in a job description and provides the recruitment effort with the boundaries and objectives of the search. Often times a company will have job descriptions that represent a historical collection of tasks performed in the past. These job descriptions need to be reviewed or updated prior to a recruitment effort to reflect present day requirements. Starting recruitment with an accurate job analysis and job description insures the recruitment effort starts off on a proper track for success. Sourcing Sourcing involves; 1)advertising, a common part of the recruiting process, often encompassing multiple media, such as the Internet, general newspapers, job ad newspapers, professional publications, window advertisements, job centres, and campus graduate recruitment programs; 2) Recruiting research, which is the proactive identification of relevant talent who may not respond to job postings and other recruitment advertising methods done in 1. This initial research for so-called passive prospects, also called name-generation, results in a list of prospects who can then be contacted to solicit interest, obtain a resume/CV, and be screened. Screening and Selection Suitability for a job is typically assessed by looking for skills, e.g. communication, typing, and computer skills. Qualifications may be shown through resumes, job applications, interviews, educational or professional experience, the testimony of references, such as for software knowledge, typing skills, numeracy, and literacy, through physiological tests or employment testing. In some countries, employers are legally mandated to provide equal opportunity in hiring. Business management software is used by many recruitment agencies to automate the testing process. Many recruiters and agencies are using an applicant tracking system to perform many of the filtering tasks, along with software tools for psychometric testing. Conclusion Human resource management is an important function not only for Tesco but also for all the companies which manage human power or which deal with people. HRM is a key point for a company for its success if that function fails or malfunctioned the company will fall because the effect of bad HRM are not friendly to the company. Company labour cost will increase and because of that cost of production will rise and the sales will decrease, Because of less Sales Company cannot stay in the market or face the competition. The difficult management function within the company in known as HRM. Lot of studies has carried our around the world by professors and professional authorities in order to maintain a successful HRM in companies This case study is written in order to those companies which need basic knowledge of HRM and for students who want to know the meaning of HRM and how that functions. Tesco is a multinational company that has spread over 25 countries with about 440,000 employees. That much of employees are a asset to a company and the management is very important else employee dissatisfaction will leave to Tesco company down as mention above. HRM is not just a management function like finance management, production management etc, its special because it always deal with real people and they are hard to handle and the understanding in to be there within the company and employee to achieve success in future.

Modern Politics on “The Strategy of Terrorism” Essay

David Fromkin, author of â€Å"The Strategy of Terrorism† makes several arguments through his article; some of which I feel are relevant to today’s political atmosphere and some which seem unrealistic. The following essay discusses four key arguments and their relevancy in today’s standards.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The most unrealistic statement made by Fromkin was in his description of a terrorist in the eyes of some people. As revolutionaries, terrorists have come to seem romantic figures to many (685). Although written over thirty years ago, it seems unimaginable that anyone could see terrorists as romantic. The author makes another reference to terrorists as men going from gunmen to heroes. While it is possible that terrorist regimes consider their leaders as heroes, it is unrealistic to think any non-terrorist society would agree. The 2001 collapse of the Twin Towers destroyed any possible visions of romance or heroism involving terrorist actions, if anyone was ever to feel that way towards terrorism.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   To look at Fromkin’s arguments in a pre-911 mindset, some of his arguments may not seem that unrealistic to America’s mainstream society. The American people have been aware of terrorism for decades, but very few physical acts of terrorism has been carried out in American soil; in comparison to overseas countries. Many American’s were ignorant to terrorism, even after the Oklahoma Bombing in 1995; which many considered not to be terrorism because it was an American man with no known organization behind his action. Although, publications would later be released linking McVeigh to the Aryan Nation organization and the Midwest Bandits (Cash & Charles, 2001). Before 911, most American’s perceived terrorism as something that happened in other countries; not in the safe and dependable United States. American’s today are much more aware of the dangers of terrorism. How does one define terrorism? Fromkin did well in answering this question, and his descriptions are still relevant today. The author’s description of terrorism as a fear tactic, using fear as a weapon, and their need for publicity in order to be successful was relevant in the 1970s as well as today. Everyday the news displays more heinous acts of terrorism in Iraq, where our brothers, husbands and other loved ones may be; and we are struck with fear. These images are daily reminders of those we lost in the 911 attacks as well. When human life is taken for reasons only known to the killers, our fear is their success. Fromkin also makes a good argument when he details terrorist strategy as a success determined by response made by the victims’ organization or country. It is my opinion that the United States has reacted as the terrorists hoped. The terrorists had hoped to ruin the economy and security of the American people. When America went to war, the implications were, and still are, innumerable. The divide of lower and upper class Americans has all but wiped out the middle class status; and today, more and more Americans are questioning the government’s motives in going to war with Iraq, the unity once found in America is no more. The final argument to be discussed is Fromkin’s outlook on the United States government as â€Å"a face and not a mask†. I wonder if he would feel that way today. As mentioned above, American’s are now questioning our government’s motives in Iraq. Scandals in the White House and throughout government agencies have become a regular occurrence, published as front page news and on the news. I would have to disagree with Fromkin’s argument; the American government most certainly does wear a mask. It is possible however, that at the time of Fromkin’s article publication, our government had a much better mask in place. In conclusion, Fromkin’s article makes several arguments about terrorism; most however are unrealistic in today’s society. What hasn’t changed however is the strategy of terrorism. Terrorists today use fear tactics and public displays of violence to produce a response. Unfortunately, many times terrorists receive the response they hope for. As Fromkin discussed, sometimes prevention is not enough, and at times inappropriate. The way to combat terrorism is to understand it, know the motivation and not to play into the hands of the enemy.

Life cycle marketing

The family life cycle represents a method via which the market for certain goods and services is segmented according to the stage in the family life that the particular consumer has reached. This marketing method takes into consideration the family configuration beginning with young, single persons with no children all the way up through marriage, child rearing, and retirement stages. The variables involved in each stage of the model include age, marital status, income, employment (career), and the existence of children (Fritzsche, 1981). One stage in this model is the bachelor stage, which describes persons who no longer live with parents but who have not married or become parents. They usually have a high level of discretionary income despite the fact that their incomes lower than average. Because of the fewer financial burdens (mortgages, children, etc.) and their commitment to recreation, such persons are usually interested in buying clothing, travel, and basic household furniture or equipment. One magazine that could be used as a marketing tool is People, and TLC’s What Not to Wear represents a television program that would be suitable to this group. Both would be effective as they cater to fashion and to the entertainment interests of that group. Another marketing group according to this model is the Full Nest One (Fritzsche, 1981). The Full Nest One stage finds new parents with their youngest child being under the age of six. The parents at this stage have low discretionary incomes because the demands of the children are placed at the highest priority (1981). These persons are therefore likely only to buy necessities, such as cereals, diapers, and children’s clothing. A television show and magazine that are likely marketing tools for this demographic are (respectively) FOX’s Are You Smarter Than a Fifth Grader   and Disney’s Family Fun magazine. Parents are likely to watch or read them with their children. The Full Nest Three stage describes older parents with high school or college age children. These persons have a better financial position, with wives likely to be at work and more discretionary income (Fritzsche, 1981). Such a household is likely to be interested in buying holidays, nice furniture, and sophisticated appliances. A good magazine for marketing to such a demographic is Travel and Leisure, as such persons are likely to have the money and time to take vacations. A good television channel for marketing to them is HGTV, as this features tastefully decorated homes that may give them ideas for buying furniture and appliances. Reference Fritzsche, D. J.

Gibe, Gybe, Jibe, and Jive

Gibe, Gybe, Jibe, and Jive Gibe, Gybe, Jibe, and Jive Gibe, Gybe, Jibe, and Jive By Maeve Maddox The verbs gibe, gybe, jibe and jive all begin with the sound [j] and are often confused. gibe (verb): to taunt, to insult. Example: â€Å"If he laughed instead of cried when someone  gibed  at him, often the  teasing stopped.†Ã‚   gibe (noun): a sneering comment, a taunt. Example: â€Å"The  teasing, taunts,  gibes  and hurtful acts are a part of me still.† gybe (verb): (sailing term) to shift suddenly and with force from one side to the other when a ship is steered off the wind until the sail fills on the opposite side. Alternative spelling: jibe. Examples: â€Å"As Phil slipped overboard, the  boom gybed.† â€Å"A gust of wind caught their  sail, the  boom jibed, nearly knocking Mr. Snider overboard.† jibe (verb): to make sense, to agree with, to fit in. Example: â€Å"The latest research findings jibe with those recorded in 1934.† The noun jive has these three meanings: 1. a type of fast, lively jazz Weve been wanting to  play Jive  since the band first started. 2. lively and uninhibited dancing. He doesnt quite bounce around like a rubber band during his jive, but does good enough to notch a 7-7-7. 3. talk or conversation, especially talk that is false, misleading, or worthless. It’s time to cut the jive and tell the truth. As a verb, jive can mean to play lively music or to dance to lively music. Example: They spaced each other about four feet apart and  were jiving  to the music. The verb jive can also mean, â€Å"to mislead or deceive.† Maybe the narcs  were jiving  him, maybe  they were  going to shoot him in the back. I searched his eyes for some clue that  he was jiving me. He wasnt.   The most common errors with these words are to spell gibe as jibe and to use jive in the sense of jibe. Here are some examples of misuse from the Web: Incorrect: Arizona Prison Privatization Proposal Doesnt Jive with Market Correct : Arizona Prison Privatization Proposal Doesnt Jibe with Market Incorrect:  But  my opinion  about that  doesnt jive  with everyone elses opinion.   Correct :  But  my opinion  about that  doesnt jibe with everyone elses opinion.   Incorrect: If your child is hurling his own silly  jibes at  the teaser, then its a mutual thing. Correct : If your child is hurling his own silly  gibes at  the teaser, then its a mutual thing. Incorrect: Put-downs, slurs, jibes, and innuendo of all kinds are never purposeless or harmless. Correct : Put-downs, slurs, gibes, and innuendo of all kinds are never purposeless or harmless. The Oxford English Dictionary validates the nonstandard use of jive in the sense of jibe as â€Å"U.S.† usage, but Merriam-Webster Unabridged (notorious for its tendency to embrace all types of questionable usage) does not. The only definition M-W offers for jibe is â€Å"to be in accord.† Its only definitions for the verb jive are related to music, misleading talk, and teasing. Two other much-cited American authorities are careful to distinguish between gibe and jibe: The Chicago Manual of Style A gibe is a biting insult or taunt; gibes are figuratively thrown at their target â€Å"The angry crowd hurled gibes as the suspect was led into the courthouse.† Jibe means to fit, usually with negation â€Å"The verdict didn’t jibe with the judge’s own view of the facts.† The AP Stylebook To gibe means to taunt or sneer: â€Å"They gibed him about his mistakes.† Jibe means to shift direction: â€Å"They jibed their ship across the wind.† or, colloquially, to agree: â€Å"Their stories didn’t jibe.† Summary The sailing term may be spelled either gybe or jibe. The latter is more common in US usage. The verb that means â€Å"to agree† or â€Å"to fit† is spelled jibe. The noun and verb that convey taunting are spelled gibe.

Arguments for and Against Humane Meat

Arguments for and Against Humane Meat Certified humane meat has been gaining in popularity as the public learns more about factory farms. Some activists call for reforms and labeling of humanely raised and slaughtered meat, but others argue we cannot work on reforms and promote animal rights at the same time. Background In a factory farm, animals are treated as commodities. Breeding sows are confined in gestation stalls, pigs have their tails cut off without anesthesia, calves spend their entire lives tethered by their necks in veal crates, and egg-laying hens are debeaked and kept in cages too small to spread their wings in. The search for solutions has focused on two paths, one reforming the system and instituting more humane standards, and the other promoting veganism so that fewer animals are bred, raised, and slaughtered. While few animal activists disagree with promoting veganism, some believe that campaigning for reforms and humane labeling is counter-productive. Humane standards can either be required by law or instituted voluntarily by farmers. Farmers who voluntarily agree to higher humane standards are either opposed to factory farming or are trying to appeal to consumers who prefer meat from humanely raised and slaughtered animals. There is no single definition of â€Å"humane meat,† and many animal activists would say that the term is an oxymoron. Different meat producers and organizations have their own humane standards by which they abide. One example is the â€Å"Certified Humane Raised and Handled† label that is backed by the Humane Society of the U.S., the ASPCA, and other non-profits. Humane standards might include larger cages, no cages, natural feed, less painful methods of slaughter, or prohibition of practices such as tail docking or debeaking. In some cases, campaigns target retailers or restaurants instead of the actual producers, pressuring the companies to purchase animal products only from producers who raise the animals according to certain voluntary standards. One example is PETA’s McCruelty campaign that asks McDonald’s to require their producers to switch to a more humane method of slaughtering chickens. Arguments for Humane Meat People will continue to eat meat for the foreseeable future, so humane standards will ensure that the animals will have a better life than they have in factory farms now.Since some people will never be convinced to go vegan, humane standards are the only way we can help the animals who will be raised for food no matter what else we do.Humane standards will eliminate the cruelest factory farming practices. Humane standards have broad-based support, so goals are achievable. Many people are opposed to factory farming but are not opposed to eating meat or other animal products. According to Humane Farm Animal Care: A recent study on behalf of the United Egg Producers found that three out of four American consumers (75%) would choose food products certified as protecting animal care over those that are not. Humane regulations on a state or federal level provide relief to millions of animals.Humane standards are a step towards animal rights. By promoting humane standards, we persuade people to care about animals, which will lead some to vegetarianism and veganism. Arguments Against Humane Meat There is no such thing as humane meat. Using an animal for food violates the animal’s right to life and freedom, and cannot be humane. Calling some animal products â€Å"humane† leads people to believe that animals do not suffer on â€Å"humane† farms when in fact, they do. For example, male babies of egg-laying hens are still killed, and male dairy cattle are still killed. Also, HumaneMyth.org explains: At all farms, large-scale and small-scale, laying hens are killed when their production declines, typically within two years, as feeding these worn-out individuals cuts directly into profits. Often the bodies of spent hens are so ravaged that no one will buy them, and they are ground into fertilizer or just sent to a landfill. Some humane standards can be woefully inadequate, even by animal welfare standards. Giving animals enough room to spread their wings or turn around does not mean they will have enough room to fly or walk around. They will still be crowded and will still suffer.Requiring larger cages or larger pens will require more space and more deforestation than factory farms already require. Nine billion land animals are killed for human consumption every year in the U.S. Giving 9 billion animals enough land to roam would be an environmental disaster.Humane meat is not more sustainable than factory farming. The animals will require just as much food and water, if not more because they will be moving around more and exercising more.Humane meat campaigns sometimes send a confusing message. Nine years after declaring victory in their McCruelty campaign against McDonalds, PETA resurrected their McCruelty campaign in 2008 to make further demands.Instituting humane standards causes some vegetarians and vegans to start consuming meat and other animal products again. Spending resources on reform campaigns take movement resources away from campaigns to promote veganism.Humane standards do nothing to challenge the right of humans to use other animals and have nothing to do with animal rights. We should promote veganism instead of more â€Å"humane† ways of exploiting animals. Animal activists sometimes debate whether promoting veganism helps animals more than humane reforms, but we may never know. The debate is one that divides some groups and activists, but the animal agriculture industry fights both types of campaigns.

Ada Lovelace - Mathematics and Computer Pioneer

Ada Lovelace - Mathematics and Computer Pioneer Ada Augusta Byron was the only legitimate child of the Romantic poet, George Gordon, Lord Byron. Her mother was Anne Isabella Milbanke who took the baby at one month old away from her fathers home. Ada Augusta Byron never saw her father again; he died when she was eight. Ada Lovelaces mother, who had studied mathematics herself, decided that her daughter would be spared the fathers eccentricities by studying more logical subjects like math and science, rather than literature or poetry. Young Ada Lovelace showed a genius for math from an early age. Her tutors included William Frend, William King and Mary Somerville. She also learned music, drawing and languages, and became fluent in French. Ada Lovelace met Charles Babbage in 1833, and became interested in a model he had constructed of a mechanical device to compute values of quadratic functions, the Difference Engine. She also studied his ideas on another machine, the Analytical Engine, which would use punched cards to read instructions and data for solving mathematical problems. Babbage also became Lovelaces mentor, and helped Ada Lovelace begin mathematical studies with Augustus de Moyan in 1840 at the University of London. Babbage himself never wrote about his own inventions, but in 1842, an Italian engineer Manabrea (later Italys prime minister) described Babbages Analytical Engine in an article published in French. Augusta Lovelace was asked to translate this article into English for a British scientific journal. She added many notes of her own to the translation, since she was familiar with Babbages work. Her additions showed how Babbages Analytical Engine would work, and gave a set of instructions for using the Engine for calculating Bernoulli numbers. She published the translation and notes under the initials A.A.L, concealing her identity as did many women who published before women were more accepted as intellectual equals. Augusta Ada Byron married a William King (though not the same William King who had been her tutor) in 1835. In 1838 her husband became the first Earl of Lovelace, and Ada became countess of Lovelace. They had three children. Ada Lovelace unknowingly developed an addiction to prescribed drugs including laudanum, opium and morphine, and displayed classic mood swings and withdrawal symptoms. She took up gambling and lost most of her fortune. She was suspected of an affair with a gambling comrade. In 1852, Ada Lovelace died of uterine cancer. She was buried next to her famous father. More than a hundred years after her death, in 1953, Ada Lovelaces notes on Babbages Analytical Engine were republished after having been forgotten. The engine was now recognized as a model for a computer, and Ada Lovelaces notes as a description of a computer and software. In 1980, the U.S. Department of Defense settled on the name Ada for a new standardized computer language, named in honor of Ada Lovelace.

Quantitative Geography Essay Example | Topics and Well Written Essays - 2000 words

Quantitative Geography - Essay Example It is not a surprise that GIS data today is used by thousands of organizations from different segments of life, from businesses, governments, educators and scientists, environmental and conservation organizations to natural resource groups and utilities. GIS is helpful in solving problems and improving processes, increasing profits, improving services, bettering education at all levels and allowing for more proper use of our natural resources.(GIS website,2007) Â  The combination of geography as a scientific branch and GIS as a way of utilizing geographic information brings us a new idea, one of geographic approach. It is a new way of thinking and problem solving that integrates geographic information into how we understand and manage our planet. This approach allows us to create geographic knowledge by measuring the earth, organizing this data, and analyzing and modeling various processes and their relationships. The Geographic Approach also allows us to apply this knowledge to the way we design, plan, and change our world. All of the above became really essential in the aftermath of the industrial and technological boom in the last two centuries, one that came at a great price of serious depletion of natural sources and serious worries about the future of our planet. Â  In its nutshell, the Geographic approach is just like any scientific, analytical method. It calls for several steps, all of which are necessary for obtaining an end result that is scientifically tested and valuable.

What I Learned from Getting Knocked Around by Steve Macone Essay

What I Learned from Getting Knocked Around by Steve Macone - Essay Example Reducing a conflict into bits of a puzzle allows the parties understand it more and construct a conclusion from such a conflict. As such it requires the reader to ask themselves exactly what the arguments are and how the arguments are put together in the conflict. Steve Macone’s piece â€Å"What I learned from getting knocked around† alludes heavily to his profile history and background. The subject and thesis is curved from an almost too popular topic of football a game that is not just a national sport but a source of entertainment for many across the globe. It is a symbol for society and common uniting factor for most audiences. This makes it an even broader thesis and serves to offer a wide background for the interplay of conflict and the presentation of ideas. He presents the subject with a resounding naivity and allows the piece to grow the subject from ground zero letting us through a trip into the world of football. The subject is discussed in the simplicity of the occurrence of the events from a naà ¯ve and unfamiliar perspective leaving out the specific expert details and rules. It is an innocent bystanders approach and explanation of football that gives an account of what football is all about. The purpose of the article falls back to the authors profile and history as an entertainer and comedian. He is in a strict sense and with regard to his accomplishments a crowd pleaser and therefore consciously or subconsciously reaches out to the audience beyond the normal impressive facts about football to the exciting and thrilling experiences of a player. This has the effect of growing multiple intentions and creating mixed reactions on the true purpose of the article. From a conscious stand one would draw a critique of the safety and actual rationale of the game beyond the impressive running and locking of horns between players. he introduces the piece with a rather fragile platform of argument â€Å"I’d known there was hitting in football but

The Problem of Induction by David Hume Essay Example | Topics and Well Written Essays - 1750 words

The Problem of Induction by David Hume - Essay Example I however, do not believe this response is an argument, and the problem of Induction maintains it’s force as a theoretically worry to serious philosophers. Furthermore Hume offers a solution to theoretical skepticism by distinguishing between the type of skepticism inquired about by philosophers, and the skepticism you should engage in in everyday life. In other words, Hume admits this problem is theoretically unanswerable, but practically speaking, is unlivable. By making this distinction, I believe that Hume makes the skeptical problem of induction less worrisome, while preserving its theoretical significance. Before going into any solutions Hume provides, we should first explain the basics of Hume’s argument from induction. The conclusion of Hume’s argument about the limitations of inductive reasoning, is that we have no basis to conclude that the future will resemble the past. The idea of cause and effect is not grounded in experience, because we cannot see c ause and effect. For example, Hume points out that we cannot conclude that fire causes burns simply from putting our hand in the fire and noticing that it burns. We only are brought to believe this through repeated attempts, and a hypothesis that we should not try it in the future. Nor are our conclusions from experience based upon human understanding or reason, because that would rely on the false implicit assumption that nature always continues uniformly. That is, we cannot legitimately conclude that things in the past will continue to follow that path out of necessity. Hume comes to these conclusions through a complex explanation about how humans come to understand things through experience. A beginning point in Hume’s skepticism about empirical and inductive reasoning, is that forming any argument about experience relies on the assumption that the future will resemble the past. He states, â€Å"In reality, all arguments from experience are founded on the similarity which we discover among natural objects, and by which we are induced to expect effects similar to those which we have found to follow from such objects (Hume, 27). In other words, arguments from experience require that we assume what we have seen in the past will happen similarly in the future. However, this premise could never be proved deductively, because that would require believing any event is absolutely necessary, but it is always possible for things to happen otherwise. It also cannot be proved causally, because that would beg the question. In other words, such an argument would assume the existence of causality, which cannot be proved, because it is the very thing in question. Hume further points out that what we immediately learn from the senses does not always lead us to discover the true underlying properties of nature. For example, simply by observing and tasting bread, we do not arrive at the conclusion that bread nourishes. The only way we know bread nourishes, is by consu ming it, and realizing that effect: Should it be said that, from a number of uniform experiments, we infer a connexion between the sensible qualities and the secret pow- ers; this, I must confess, seems the same difficulty, couched in different terms. The question still recurs, on what process of argument this infer- ence is founded?...It is

Computer security Essay Example | Topics and Well Written Essays - 1500 words

Computer security - Essay Example It also provides recommendations for them. Threats to the system include the absence of multilayered protection. The ease with which the junior officer accessed the DRS is suggestive of implies threats too. The backup copies were not functional and the ease of access meant that the information is at a greater risk. There were also a number of security principles that were broken. These include the need for professionals to have knowledge about their profession, lack of responsibility by the duty manager etc. The recommendations encompass the development of multifactor authentication, a risk management system, introducing firewalls etc. Introduction One of the oldest definitions for security is that it is the process whereby steps are taken to minimize vulnerabilities of assets and resources. Security encompasses the elements of keeping information confidential and of upholding the integrity and availability of resources; these three elements are often used to describe computer securi ty goals (Stallings 2009). It is often associated with the three As: authentication, authorization and accountability. Security does not entail the elimination of every threat or vulnerability to the system; rather security implies that there is no such thing has 100% security, although one can get close to it. ... On the other hand, security will be high if the data is secured tightly, causing obstacles in accessibility (Cross & Shinder 2008). Computer security is also regarded as a compromise; it is seen that the greater the security, the difficult it is for users to work with the system (Salomon 2006). The case study provides an example of how security lapses can occur and expose the system’s vulnerabilities. This paper looks into the threats and vulnerabilities that the event exposed and examines the security principles that were broken. It also provides recommendations for buttressing the security of the computer systems based on the identified threats and vulnerabilities. Identifying Threats and Vulnerabilities Threat to a computing device is referred to as any potential happening, either unintentional or malicious, that may cause undesirable effects on the asset (Newman 2009). One of the main security issues that the event brought into limelight was the ease with which a junior em ployee was able to change the keys for the encryption on the database. There was no layered security protocol and a simple password provided the user access to valuable information. Moreover when the junior officer had logged into the system using the password of the duty manager, a message came up asking the officer to change the crypto keys on the DRS. Giving away the password to a junior officer and allowing him access to company files and other information which constitute a large value of the company gives rise to threats to the security of the computer. The junior officer did not know much about the application that launched to change the keys. The application could have been a malicious software too and could

The Poblem of People Having only Online Friends Essay

The Poblem of People Having only Online Friends - Essay Example According to the paper social anxiety disorders usually manifests as a persistent fear of social performance situations where a person is exposed to unfamiliar people. The individual sometimes fears that he might act in an embarrassing way and be humiliated in the process. In these instances, their exposure to social situations usually triggers their anxiety. As a result, such anxiety often manifests in their panic, crying, freezing or shrinking from social situations. The person afflicted with this disease is most often aware that his fears are exaggerated; however, he cannot control or manage such fears. As a result, these people avoid these social situations and veer away from situations which may cause them embarrassment. Their attempt at avoiding these embarrassing social situations often interferes with their lives and their normal academic, social, or professional activities. This essay highlights that the internet is often used by these individuals in order to acquire social interactions. They often find the internet a more comfortable place to meet and interact with other people. They find it a more comfortable setting because their fears in being embarrassed or humiliated do not exist in this setting. However, as a result, their moments of interaction become limited to the internet or online setting.

What do Happiness Studies Study Does Happiness Change After Major Life Essay

What do Happiness Studies Study Does Happiness Change After Major Life Events - Essay Example He also went furhter in dissecting the etymology of the word â€Å"happiness† by tracing to its root word â€Å"hap†, meaning chance and luck whether it is good and bad in his effort to find the true meaning of happiness. The other study of Lucas that our set point of well being or our normal selves is predominantly biologically determined and our response and how we adapt to happiness life changing events in life fluctuates around that levels but will ultimately settle back to this normal state of well being. Griffin in his study about happines begun by assigning a value at the beginning of his argument particularly when Griffin cited eudaimonia† referring to â€Å"having a good guardian spirit† because that defined the trajectory of his argument. He begun associating martyrdom with happiness and formulating imaginary mathematical equation that being â€Å"happy now† and â€Å"more happy instances† vis-a-vis lesser unhappy instances would net to a happy life that made the paper problematic. The analysis was quite simplistic particularly when Griffin added Hume’s standard of taste because it required putting standard to happiness that can be likened to the concept of right and wrong in being happy. Any modern student of philosophy can refute this argument because we already know that there is no universal formula or standard of happiness. What makes one elated with happiness may be a casual circumstance to another. The bottomline is, what makes one happy will not necessarily make another happy. This test can easily be applied to refute the paper’s argument by also using one of Griffin’s example which is the woman from India who is â€Å"badly oppressed and what from the outside looks like a miserable existence† (2007:141) and might be content with small improvement of which such contentment, Griffin argued, would not necessarily mean she has a â€Å"happy life†. The trouble with Griffin ’s line of argument in this example is he already put a qualifier in the his hypothesis by framing it as â€Å"pathetically content with a small improvement in what from the outside looks like a miserable existence† (141). There was already a value judgment in the hypothesis which was supposed to be in the conditional because it is yet to be argued. Such, the conclusion is certain to arrive that she will not be happy because the line of reasoning did not provide room for refutation. It can be contended however that the woman, as opposed to the paper’s contention, is happy to the slightest improvement that will come in her life and not necessarily pathetic as what Griffin has framed. With how Griffin framed his words, it seem that he has not experienced poverty because it became an automatic reaction to him to say that a poor woman despite being content of having little will still be unhappy. It is like refuting his own argument because in his words, Griffin also mentioned that â€Å"one’s life is happy if one is content that life has brought one much of what one regards as important† (2007:140). Perhaps in his value system, slight improvement is not significant to be considered important but for those who were already exasperated with poverty, a moment of relief and the slightest of improvement is already bliss. Griffin is arguing from the point of view of a rich man who has not sufferred deprivation of his basic need such that, the provision of basic material

Other forms of communicators within the interaction base the assessment on the effectiveness of the feedback to the listener while responses take the performance form against comprehension tests. The attentive behaviors and compliance improve on listening to arguments on feedback past listening. Listening physiology plays an essential role in the manner my sister’s listening functions. Auditory and visual are sensory acuities that are based on basics of listening. Deterioration based on age-related issues and sensory mechanisms lead to eventful loss of verbal content and nonverbal dimensions in communication (Pfeiffer and Pfeiffer 87). Listeners are intended receipts of sent messages. In the reception process, listeners employ visual and auditory sensory receptors. The listening processes include hearing sounds while hearing and listening does not have synonymous functions as most people assume. Auditory message reception is a detailed process that involves the intricate mechanism of hearing. Sound should enter the middle ear towards vibrations of the tympanic membrane and later conducted to the inner ear and lastly, to the brain. Problems faced in the hearing mechanism compound receptive processes (Adler, Rosenfeld, and Proctor 121). The neurological make-ups of my sister’s listening are influential factors. Hemispheric specialization research suggests that left part of the brain is more objective, rational, organizing processor and while the right is more emotional and intuitive.

Polymer Suspension Based Shear Thickening Fluid Fabric

Polymer Suspension Based Shear Thickening Fluid Fabric Polymer suspension based shear thickening fluid-fabric for protective applications was a new idea. Shear thickening fluid was also known as STF. Generally STF contains liquid medium and solid particles which can be inorganic or organic based. Basically, the viscosity of the Shear Thickening Fluid (STF) will be increased when shear stress increasing. By exploiting this fluid deformation from STF, for the fabric itself, the friction between yarn-yarn and fiber-fiber will be increased drastically when force applied over the fabric composite. Then, the fabric itself will be having higher energy absorption when STF impregnated with the fabric itself compared with un-impregnated fabric composite. The reason for this selection was motivated by previous works in this area, as well as the beneficial characteristics provided by these two materials. US Patents 5599290 and 5545128 have developed Bone fracture prevention garment and method. In these two works, carried out by the same authors, the patent outlines a design used to resolve the issue of the harmful effects of impacts on the bones of elderly individuals. This design was described as being composed of the following: the component includes a dilatant material that was relatively stiff near the time of impact and relatively fluid at other times. In a preferred embodiment, the invention provides a hip pad, possessing a thickness small enough to be compatible with wearer acceptability, that conforms to the shape of the body during everyday activities such as walking, sitting, and sleeping, and was thus comfortable to the wearer (5-14). In order to model the rheological behavior of these fluids, it has been proposed to use a power law analysis with the relationship between the viscosity and shear rate represented by ÃŽÂ · = k à ½n-1 Where k is the fluids consistency and n is the power law exponent specific to the region of high or low viscosity. According to Barnes, the shear-thinning and shear-thickening regions can be accounted for by, using the sum of two power laws, with one value of n less than unity and one greater. (8) The rheology studied will be focused on colloidal suspension rather than hard particle suspension. Hard particle suspension like silica particle, was extensively studied by many researched over the world like Wagner and Lee Barnes (5 8) .They claimed, the hard particle suspended in the polyethylene glycol (carrier fluid) will exhibit shear thickening behavior by varying the volume fraction of the particle over carrier fluid from, above 40% to 55%. 30% by volume fraction will not exhibit shear thickening behavior but in Ragvahan experiments showed (10), by using 10% volume fraction of fumed silica suspended in the Polypropylene glycol (PPG), shear thickening behavior had occurred but likely referred to particle agglomeration( flocculated gel) rather than hydrocluster because fumed silica, naturally have low surface area and larger particle size. In the experiment, the onset transition called critical shear rate seems having two points, the higher and the lower shear strain, due to th e original structure of the carrier fluid itself (polypropylene glycol). The formation of vinyl group and straight chain in PPG gave two formations of clusters (10). Colloidal suspension study was not emphasized and thoroughly studied because of the complexity of the colloidal system itself, which normally involved many factors such as steric and electrostatic stabilize, stability of the suspension and the formation of the hydrocluster via modification of the interaction particle of the colloidal suspension. In chapter 2, theoretical discussion about colloidal suspension which contributed to the new phenomenon of Shear Thickening Fluid (STF) such as structure-relationship of the colloidal suspension in polymer solution and Solid/Liquid transition (SLT) and also liquid/Solid transition (LST) [17]. According to the DVLO theory, stabilization of particle in the suspension with steric and electrostatic (will be have detailed explanation in the chapter 2) charges are important parameters to be investigated. The colloid particles were also known as surface charge particle. It involved the attraction and repulsive force for every single particle in the colloid dispersion or suspension, which contributed to the shear thickening behavior of the STF. In this paper, colloidal suspension rheology will be main topics, by relating it with the structure-relationship and LST theory. In the chapter 2, more detailed onset transition of STF will be extensively discussed. Conventionally, the onset transition involved Order-Disorder transition (ODT) and hydrocluster. The main criteria in Shear Thickening Fluid (STF) were to predict critical shear rate which was the critical point when the particles were suspended in the STF. It started to cluster with each other, exhibiting shear thickening behavior upon increase in shear rate. There were many factors in STF, some of them were, volume fraction dependence (between particle and carrier fluid), particle shape and size dependence (porosity) and particle interaction dependence. The particles can be normal charge (hard particle such as fumed silica, clay and any metal oxide particle) or colloidal particle (with charge). In this paper, fumed silica will be used as a main material for hard particle as well as and colloid dispersion. Fumed silica will be turned into colloidal suspension by surrounding the charging over its surface particle. The main principal of colloidal suspension for this study was based on DVLO theory. Therefore, by studying the electrokinetic for each suspension, relation between this study with measured rheology through the power law index and yield stress value, there are possibilities to relate the structure- relationship in colloidal suspension of STF with onset transition (SLT LST) evaluated. There were two basic requirements for exhibiting shear thickening behavior from colloidal suspension [raghavan, wagner, barnes], firstly, the volume fraction of the solid in the suspension must be very high and secondly, suspension must be nonflocculated or deflocculated STF Fabric composite will be impregnated with STF has great potential in bullet proof application especially for soft armor. The vest will be having higher flexibility and less heavy than conventional soft armor. Wagner and his team claimed, STF will increase the friction between yarn-yarn and fiber-fiber by 500% using pull out yarn test. Also, by using NIJ as reference stabbed and puncture resistance test (NIJ 115.00) for STF Fabric composite, it easily passed level 1 protection. For the bullet test, also NIJ as reference, it showed interesting results. Instead of higher penetration from the bullet (9mm) to the conventional fabric composite, for STF-Fabric composite, bullet was deflected away (rebound) and had less significant mark over the top of the clay in tested frame panel. Basically, fabric composite will be placed over the top of the clay. The mark of the clay will be used as reference for the dissipated energy (energy absorption) from the test. A bigger diameter of the mark and the depth for the mark was deeper indicating the fabric composite has a low dissipated energy system. Smaller diameter of the mark and less depth of the indented clay, showed, a higher dissipated energy system for the fabric composite. 1.2 Problem Statement Wagner found that STF had rheological characteristic of dilatant but studied on the use of hard particle in suspension. Colloidal suspension of fume silica in polymeric aqueous media was performed by other researcher but they studied only ionic strength and critical shear rate effect. In depth study on formation of hydroclusters in colloid need to evaluated to relate structure relationship between shear thickening behavior of polymer suspension with regard to composition (volume fraction), particle porosity, size and shape of particle. Hence, viscosity measurements were evaluated for different polymer systems to determine the effect of these systems on critical shear rate and shear thickening phenomena. Stabbed and puncture resistant fabric composite employing STF with high spike and knife impact performance can be affected by the formulation of STF and adhesion between STF suspension and fabric yarn. Hence, this study is hoped to solve the problems faced by indepth understanding on rheological and performance aspects in the development of STF fabric composite for protective applications. 1.3 Objectives Of Study The specific objectives of the project include: To determine physical colloid properties of colloidal suspension from hard sphere particles and colloidal dispersion via zeta potential studies. To determine the rheological behaviors of the colloidal suspension from the effects of repulsion system present during steady shear experiments. To fabricate STF fabric composite using various layers of Kevlar 49 and cotton fabric and determine stab and puncture resistance of STF fabric composite according to standard NIJ 115.00 tests.

Al: Rheology of Polymers near Liquid-Solid Transitions CHAPTER TWO LITERATURE REVIEW 2.1 Shear Thickening Fluid (STF): Introduction Review Shear thickening fluid, basically have two different types of fluid behavior shear thinning and shear thickening. There are two types of shear thickening behavior in the fluid behavior. First, Shear thickening is a non-Newtonian flow behavior (dilatant) observed as an increase in viscosity with increasing shear rate or applied stress also known as time independent material (Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003). Non-Newtonian flow behavior (rheopectics) observed as an increase in viscosity with increasing duration of stress (shear rate constant) known as the time dependent materials which have a memory to deform over period of time ( figure 1). Concentrated colloidal suspensions consisting of solid/hard spheres particles dispersed in a carrier liquid have been shown to exhibit rheological shear thickening behavior resulting in large, sometimes discontinuous increases in viscosity above a critical shear rate. This transition from a flowing liquid to a solid-like material is due to the formation of shear induced transient aggregates, or hydroclusters, that dramatically increase the viscosity of the fluid (Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003). For stabilize the STF and avoiding agglomeration behavior, co-solvent is added and it must be done because STF has a very strong molecule interaction between particles and carrier fluid (attraction force) rather than repulsive force when force is applied at specific time (critical shear rate and critical shear stress) [Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003]. The Shear Thickening Fluid (STF) is the combination of the particles suspended in the carrier fluid. Figure 2 showed the STF curve when shear stress applied on the material. The particles used can be made of various materials, such as Silica Dioxide or other oxides, or polymers such as Polystyrene (PS) or Polymethyl methacrylate (PMMA), or other polymers from emulsion polymerization. Generally, particles can be in various shapes like spherical, elliptical, disk-like or clay particles (Barnes, 1989). The particles can be stabilized in solution or dispersed by charge, Brownian motion, grafted polymers and others. Then, pH value of a suspension also contributed to the stability of suspension via colloidal condition such as steric repulsion and electrostatic system. The effects of pH value, concentration of the surfactant, and ionic strength of the surfactant are major factors for the colloidal suspension. This influence parameter is due to the agglomeration particle size (F. Rey, M.A. Ferreira et al. 1995).These are basic parameters in the rheological suspension and colloidal suspension system. Many studies of shear thickening fluid system (Barnes 1989, Hoffman 1998, Wagner 2004), focus on the colloidal particles only such as nanoparticles colloidal silica and monodisperse silica, which is it is well known as a very stable individual particle interaction in the suspension [Brownian suspension]. In this paper, electrostatic stabilize and steric repulsion system is used to control the interparticles interaction in the rheological suspension. Electrostatic stabilize is less studies due to the complexity in the rheological suspension. Concentration and ionic strength of the surfactant are the main parameter of this paper and the final pH value is critical measured in order to exhibit rheological shear thickening. F. Rey, and M.A. Ferreira in their paper Effect of concentration, pH, and ionic strength on the viscosity of solutions of a soil fulvic acid claims, all the parameter in this studies showed the dramatic instant result of the suspension due to the gel point of the suspension or well known as isoelectric point (iep) by adjusting H+ present in the rheological suspension. in addition of steric repulsion system, making a barriers for the individual surface particle is a intention in this paper. The double layers of the barriers (thickness) due to the zeta potential and elec trokinetic theories are independent from the shear stress during rheological experiments. Because of the main intention of this paper are to determine the factors involving onset transition of the STF due to the interparticle interaction dependence which are closely related to the colloidal suspension rheology and the effects of the onset transition (rheological behavior) for the stab and puncture resistance test of fabric composite. Then, the co-solvent that are used, it can be aqueous in nature and non-aqueous which can be chosen to stabilize suspension system The co-solvent should be environmentally stable like ethanol and methanol, so that, they remain integral to the fabric and suspended during service. Another function of co-solvent is to lower the viscosity of the STF, so that impregnation process of fabric composite becomes efficient and easy. By adjusting the viscosity of the STF, areal density of final fabric composite can be alter and also monitored. The particles must get through and suspended in the fiber-fiber and yarn-yarn [lee wagner et al 2003]. The result from the good impregnation process is the friction force between yarn-yarn and fiber-fiber will be increased [lee wagner et al 2003]. But in this paper, by using information from wagner and other researchers, a variation of the drying temperature for the STF and STF- fabric composite will be designed and tested via thermal degradation technique ( pre-degradation) and swelling behavior of the STF-fabric composite after at the different drying temperature. The idea are to avoid pre-degradation region and swelling behavior of the STF in the drying process which is believed will reduced the performance of the fabric composite due to the following factors, degradation of the STF and STF-fabric composite due to the drying temperature and swelling behavior of STF. By combination those factors, believed, the internal friction between fiber-fiber and yarn-yarn will be reduced which is making inefficiency of energy absorbtion or dissipated energy for fabric composite (Wagner 2004). 2.2 Mechanism of Shear Thickening Fluid (STF) The mechanism of STF normally can be described via hydrocluster theory and order-disorder theory. The similiarity of these theories is a idea of a new macrostructure formation occurred, furthermore, it are closely related to rheological experiments such as temperature and time factors. A few researchers like Barnes (1989), Hoffman (1998) and wagner (2004), claimed colloidal factors such as different types of carrier fluid, particles porosity, and volume fraction of particle suspended. But, these two theories still cant explain in detail about the mechanism of STF. Wagner and his team claimed the formation of hydrocluster must be a deflocculated suspension and major parmaters of STF are volume fraction, interparticle interaction, and particle porosity. A new theoretical transition will be proposed for STF behavior. Liquid-Solid transition (LST) or semi-solid transition involving the relaxation state of the fluid during transition which is normally include the changes of loss and stora ge modulus during transition and believed new formation of a new macrostructure are formed during rheological experiment. This a new macrostructure formed due to the formation of the attraction force and repulsion force in the STF, which is believed closely related with double layer theories in zeta potential theory. LST theories is based on the transition of the material due to the changing of the complex modulus which are can be translated into the formation of gel (stiffness) and relaxation state of the material during near transiton and at the onset transition. 2.2.1 Hydrocluster The most related theories to the shear thickening behavior are the hydrocluster theory. Basically, the hydrocluster will be occurred when the balance force from shearing flow in the concentrated suspension and the force rising from particle particle (interparticles) interaction (Bender and Wagner 1995).There are two conditions, first via colloidal factors (steric and electrostatic repulsion) and particle interactions between particle-particle and particle-carrier fluid (Bender and Wagner 1995). Figure 3 showed the formation of hydrocluster, when the applied shear stress on the STF. The formations of hydrocluster are still extensively investigated by researcher in the entire world. The main interest of this unique behavior is the onset transition (critical shear rate) from liquid state to solid or gel state. This phenomenon involving the rapid changes of fluid viscosity in a second whether applied it with shear stress, applied electric field (refer to the ER fluid), and applied magnetic field (refer to the MR fluid). There are specific equipments for detection of this phenomenon such as optical rheometer, small angle neutron scattering (SANS), and two beam light laser scattering. But with all this equipments, still the formation of hydrocluster is unknown phenomena. According to this theory, at the lower stress (below critical stress, maximum volume packing fraction) interparticle interaction either Brownian motion or electrostatic, making the concentrated suspension is easily flow (shear thinning behavior and viscosity of the suspension become lower) due to the particles slippage in the carrier fluid. As the stress is increased, the attraction forces is slightly increases than repulsion force in between particles of the concentrated suspension (particles aggregation become larger and the viscosity of the suspension become higher). When the magnitudes of the shearing force are equilibrium to the interparticle interaction, the particles in the concentrated suspension become cluster also known as hydrocluster. This theory is first suggested by Brady (Bossis and Brady 1989) as a result from stokesian Dynamics simulation and then, supported by optical rheological experiment by wagner (Bender and Wagner 1995). Basically, these phenomenons are closely related with phenomenon of Resonance in physic. In physics, resonance is the tendency of a system to oscillate at greater amplitude at some frequencies than at others. These are known as the systems resonant frequencies (or resonance frequencies). At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibration energy [the fundamental of physic 1999]. 2.2.2 Order-Disorder Theory The order-Disorder mechanism is first suggested by Hoffman (Hoffman 1972) which obeserved the monodispersed supension under shear generate different patterns at critical shear rate ( before and after). According to this theory, when the suspension is sheared, particles is ordered in the specific formation ( hexagonal or pentagonal) of packed layers parallel to the plane of shear. After a crtical stress is reached, the instabilities in the formation of packed layers become greater and particles are out of the formation. Then, these particles collide and jammed to each other and produce in the rise of viscosity. An example of these pattern can be seen in figure 4 Hoffman monitored the monodispersed suspension under shear and showed that figure 4(A) corresponds to the order formation of the packed layers while figure 4(B) is disorder or random formation of the packed layers after critical shear stress is reached. The illustration of the phenomenon for the order- disorder formation of the packed layers that suggested by Hoffman can be seen in figure 5. those formation is captured by the Hoffman by using a simple shear in figure 4 (A) is same formation in the figure 5 (A). Hoffman predicted that, those formation occur due to the strong surface bonding in the monodisperse suspension which normally reffered to the hydrogen and van der waals bond. In figure 5 (B), the disorder formation occurs when sample shear above critical shear stress. Particle are collide and jammed each other and produce in rise of viscosity due to the agglomeration of the particles. 2.2.3 Introduction Liquid-Solid Transition (LST) In this paper, a new concept theoretical onset transition of STF will be proposed. The main ideas of this theoretical concept are the macrostructure of the fluid are changes during onset transition from liquid state to the solid or gel state, and liquid- solid transition state which is normally involving the relaxation state (). The transition also can be state as semi-solid transition at the critical shear rate. This paper, also will be investigated the formation of the transition by using colloidal particles which are stabilize by using two system, steric and electrostatic repulsion system. LST involves many such of factors, such as theory of gelation, branching theories, and percolation theories. All the theory in LST are closely related to the formation of the macrostructure, whether effect on the temperature surrounding or over time. 2.2.3.1 Theory of Gelation The LST of polymers is also technically important since it occurs in nearly all of the common fabrication processes. Examples are injection molding of semi-crystalline polymers (where the surface quality of the finished parts may be affected by gelation shear thickening fluid (STF) and processing of crosslinking polymers. Therefore, the onset transition for STF can be detected by using LST. There are several theories in gelation are normally used in LST. First is branching theories and second is percolation theory. The onset transition are very important to the STF for comparison with the hydrocluster formation theories and order disorder theory and proposed new theoretical idea for the rheological behavior due to the factors affecting the performance of STF such as molecular weight dependence, volume fraction dependence and particle particle interaction dependence. Those all factors which affecting the performance of STF had been discussed in previous sub-chapter. 2.2.4 Description of the Phenomena for Shear Thickening Fluid (STF) Basically, the phenomenon of STF is investigated by using a lot of parameter in the last two decades. Volume fraction, particle porosity and interparticle interaction dependence is a major parameters for STF. In this paper, molecular weight of carrier fluid is added in the STFs parameter, in order to increase the potential parameter for the STFs phenomenon. 2.2.4.1 Volume Fraction Dependence Volume fraction factor is the main parameter in the shear thickening fluid [STF]. In general, a solid or hard particle which is suspended in the carrier fluid such as ethylene glycol, polyethylene glycol or other carrier fluid which are aqueous in nature or non-aqueous in nature can exhibit shear thickening behavior at the minimal range of volume fraction in between 30% to 49%. Above 50% of volume fraction, the rheological shear thickening behavior can be measured at lower shear rate but it depending on the complex viscosity of the suspension which is it is related to another parameters like particle size and porosity. Meaning, surface area and aspect ratio of the particle are greater influenced on the final viscosity of the STF. One parameter that has a huge effect on the critical shear rate is the volume fraction. At low volume fractions (below 0.5), shear thickening is either less dramatic or not significant [Characterization of Shear-Thickening Fluid-Filled Foam system for Use in Energy Absorption Devices, Jose 2004]. Wagner and his team also claims, colloidal silica ( 14nm) which is suspended in the polyethylene glycol, less than or 30% volume fraction of STF will producing less or no significant of thickening behavior either at low shear rate or higher. Raghavan and khan which studying the rheological behavior of fumed silica suspended in low molecular weight polypropylene glycol claim, non-flocculated suspension exhibit shear thickening at 10% [w/w] under steady flow and strain-thickening under oscillatory shear. Strain-thickening refer to the abrupt increase in the complex modulus [complex viscosity]. Fumed silica generally known has higher agglomeration size up to 140 micron. Therefore, volume fraction has less significant affected on the shear thickening behavior. The agglomeration size is the main factor in the Raghavan and Khan studies (figure 2.2.4). The results of Barnes demonstrate that at volume fractions in the range of 50 %, the shear thickening behavior is expected and predictable. In addition, theoretical analysis of the maximum volume fraction of monodispersed suspensions predicts this value is Ømax=0.605, where this value corresponds to, the volume fraction for a cubically stacked hexagonal packing (Boersma et al. 1989). 2.2.4.2 Molecular Weight of the Carrier Fluid Dependence Molecular weight of the carrier fluid is a new parameter in the STF. Wagner and his team reported that the viscosity of the carrier fluid is important to predict the onset transition from shear thinning to the shear thickening behavior in the STF. A difficulty occurs from getting exacts experimental measurement of the effect of carrier fluids due to the reality that changing the carrier fluid affects the interparticles interaction. In this paper, by monitoring the zeta potential of the carrier fluid, those two effects (molecular weight dependence and Particle-Particle Interaction Dependence) can be separated. The onset transition of STF will be a main indicator for this parameter neither the suspension are flocculated or deflocculated. The idea of used difference molecular weight is cames from colloidal suspension which prepared by raghvan, in his experiment polypropylene glycol (PPG) as a main carrier fluid. He are experimental the effect of the rheological behavior for fumed silica suspended in PPG at lower concentration (mass fraction), and showed the STF behavior at low yield stress (figure 6). The experiment by raghvan is difference from wagner and barnes, which used colloidal particle from Nissan Chemicals (MP4540) and suspended in PEG 200 at high concentration for exhibit shear thicknening behavior (figure 6). Therefore, when turnable fumed silica particle into colloidal fumed silica via steric and electrostatic repulsion system, suspended it in the different molecular weight of carrier fluid at various particle loadings, believed, the suspension will exhibited shear thickening behavior at low yield stress. 2.2.4.3 Particle-Particle Interaction Dependence Interparticles interactions are very important in determining the shear thickening behavior of a suspension. Flocculated suspension will not exhibit shear thickening (Barnes 1989), but instead they will show shear thinning, as shown in figure 7. Basically, the flow behavior of a suspension is extremely affected by interparticle interaction. These phenomenons also refer to the final condition which refers to the pH value of a suspension. Therefore in table 1, the Floc sizes are monitored due to the effect of pH value, electrolytes, and polymer on a kaolin suspension. Because of flocculation is expected to begin at lower pH values, namely edge to face that kaolin is positively charged and de-flocculation at higher pH values it carries a net negative charge on the surface. (Nongkhran Chaiwong 2008). The flocculation of kaolin depended on pH, electrolytes and polymers flocculants. Floc size and floc strength increased with increasing of cation valency in the electrolytes and increasing of molecular weight in the polymers (Nongkhran Chaiwong 2008). The information that gathered from table 1 is important for the colloidal suspension
