Muslim Cities DBQ Essay

The Post-Classical Era was a time of goodness in the Middle East. Goods were plentiful, Islam was spreading, and the people were wealthy. The Muslim cities spread innovations throughout the world. The document groupings for the discussion of this topic are as follows: Documents 2, 1, and 5 are for city significance. Documents 3, 5, and 8 are for importance of trade. Finally, documents 4, 6, and 9 are for government and its role. Document 7 has been omitted due to the fact that it does not support my thesis. Muslim cities were abundant with knowledge, which they spread throughout the world. Scholars of all religions studied in Muslim cities, which were some of the first cities to produce books. In Document 2, a Muslim historian describes Cordoba, stating: â€Å"Unto it flocked seekers of science and poetry, for it was a resort of the noble and a mine of the learned.† It was a center of knowledge-seekers, perfect for any type of learned person. As the scholars came and went, they spread their knowledge with them, eventually spreading it all over the world. In addition to having much knowledge, Muslim cities also accumulated much wealth. Document 1 describes Damascus as â€Å"the paradise of the east†, discussing its luxurious features. Document 5 discusses the highly-priced silks that were sold in Muslim cities. I request an additional document, in which a non-Muslim describes Muslim cities, to better understand an outsider’s point of view. Trade was a large part of both Muslim and Arabic culture. It was how ideas and innovations spread all over the world; simply through word of mouth. Document 3 mentions Cairo’s numerous shops in the 11th century, of which the Sultan owned. Cairo was a rich city, of which was popular for trade. Document 5 describes trade in Tabriz, and the expensive materials that were traded. Document 8 is a map that shows numerous Muslim trade routes across North Africa, Southern Europe, and several parts of Asia. Muslim traded in many parts of the Eastern world, travelling by both land and sea. I request a trade catalog, to better prove where Muslims may have traded in the Post-Classical Era. Muslims were not always secure in government. In Document 4, Caliph Abd al-Malik forbade Syrian Muslims from making annual pilgrimage to holy cities  (some of which are mentioned in Document 9) due to the fact that they had a high chance of being attacked. The Muslim people were upset, but they were unable to convince their leader to change his mind. In Document 6, walls were built to guard Muslims from attackers (which was not always successful; as the Mongols and the Crusades had been successful attackers). In conclusion, The Muslim cities spread innovations throughout the world. Their populated and learned cities were a gateway to trade, which lead to successful trading all over the world. They shared their ideas with many nations, despite the fact that they occasionally had a weak government.

Common Network Vulnerabilities Essay

â€Å"Businesses, governments, and other organizations face a wide array of information security risks. Some threaten the confidentiality of private information, some threaten the integrity of data and operations, and still others threaten to disrupt availability of critical systems† (Sullivan, 2009). Since such security risks are always going to present in the cyber world, businesses and organizations need to fully be aware of any vulnerabilities in their systems. The initial realization of any organization’s vulnerability can only first be understood through the knowledge of what vulnerability means. A vulnerability is a security weakness but not a security threat. It is what needs to be assessed in order to examine an organization’s network. One of the main network vulnerabilities facing IT managers today is the absence of encrypted data being transferred and received between uninformed users and the lack of knowledge and understanding within an organization’s internal structure. Network vulnerabilities are present in every system and with the constant advancement in knowledge, programs, and technology; it can be extremely difficult to rid all vulnerabilities in any infrastructure. Whether it is implementing hardware or beefing up software security, no one method of protecting a network can be greatly increased unless the users and IT professionals behind the update are up to speed on what is happening. To begin, all users in an organization or business need to be aware. Be aware of your surroundings. Be aware of the software that you use on a daily basis, and the information that is being passed between everyone. Security awareness in any infrastructure needs to be the center of any cyber security business program. In many respects, the challenges of implementing and managing effective technical controls pale in comparison with the difficulties in addressing organizational weaknesses, such as insufficient or ineffective security awareness training† (Sullivan, 2009). Companies that don’t provide security awareness and training are leaving open pathways into their network (McLaughlin, 2006). From an IT manager’s standpoint, companies are fully aware of the threats that their organization is faced with everyday. From a survey conducted from nearly â€Å"550 small and midsize businesses, it was found that human error was the primary cause of nearly 60 percent of security breaches during the past year† (McLaughlin, 2006). This 60 percent clearly states that the primary holes in any organization’s security remain user problems and insufficient training throughout the company. â€Å"The alarming part is that little is being done to change cultural behavior† (McLaughlin, 2006). Even knowing that the lack of education and training cause companywide vulnerabilities, changes and training continue to lie on the wayside and be less of a priority rather than a major one. The Internet is rapidly growing and evolving and people need to evolve with it. The Internet is ultimately becoming the staple for all businesses today. â€Å"Businesses from all over the world have found the Internet to be a cost effective and reliable business tool. Indeed, in the last few years, in addition to conventional business transactions, many of the controls systems (SCADA) that support national and public utilities are adopting the Internet as a core data transport method. This has resulted in businesses and societies becoming critically dependent on the continuous operation of the Internet† (John, n. ). These dependencies need to then be addressed to provide critical support for end user vulnerabilities. End user vulnerabilities need to first be recognized within a business and proper steps need to be taken to adequately train employees. â€Å"Most of the flaws that emerge in the security and vulnerability assessment realm are due to misconfigurations and poor application of corporate security practices, which points to a need for training† (McLaughlin, 2006). Businesses need to include security training and awareness; this being the first step in the correction of network holes. In my opinion, security awareness is the basis of all network flaws. Because network security is extremely important, businesses need to make it a top priority to have a network infrastructure assessment. Networks are becoming increasingly complex and by executing a network assessment it will help IT managers ensure the company’s network is operating at peak efficiency. â€Å"The vulnerability of the system depends on the state of the system itself, on the capacity of a hazard to affect this state and on the undesired consequences the combination of the hazard and the vulnerability will eventually lead to† (Petit & Robert, 2010). Known vulnerabilities of a security infrastructure require a situational awareness. â€Å"This includes knowledge of security software versions for integrity management and anti-malware processing, signature deployments for security devices such as intrusion detection systems, and monitoring status for any types of security collection and processing systems† (Amoroso, 2011). In addition to an entire infrastructure assessment, there must be companywide training classes. These trainings need to help employees understand not only the importance of network security, but also how their actions can impact everyone and everything around them. According to a Booz Allen Hamilton survey, the nation’s cyber defense is seriously challenged by shortages of highly skilled cyber-security experts† (Vanderwerken & Ubell, 2011). This poses one major issue; the people being hired to run elaborate business networks are unqualified and inadequately trained. These businesses must provide high-level in-house training programs to the experts as well as the entire workforce to ensure the integrity of internal and client systems and to avoid the cyber threats surrounding the business. Training must be provided to end users to provide overall awareness and give them the general knowledge needed to maintain the businesses integrity and a sufficiently working network. This simple, yet effective training will provide any business with a sufficient return on investment. â€Å"As long as there are cyber criminals ready to strike, your company remains vulnerable. Vigilant cyber-security training and education must be your company’s top priority† (Vanderwerken & Ubell, 2011). Even though a business can provide the necessary training through company ide programs, the biggest vulnerability in an organization are the negligent employees who don’t care or don’t want to participate in the proper security procedures. Most companies are oblivious to the fact that the most pervasive attacks on a network are caused by gullible and negligent employees clicking and opening invasive files embedded in emails and data from beyond the company’s network firewall. â€Å"Despite strenuous efforts by most companies to alert personnel to email and Internet behavior that opens up firms to invasion, employees continue to do foolish things. As more access is given to the end user by means of mobile computing, cyber-crime prevention has to be a top priority. The corporate landscape requiring protection is multiplying at very quick pace† (Vanderwerken & Ubell, 2011). Another major aspect in training is to be familiar with the upgrading of a network with new hardware. Such an update is a suitable idea but the installation and a working knowledge of how to use and implement this new technological hardware is essential. Many companies just don’t understand how vulnerable they are in areas they never would expect there to be flaws, such as hardware purchasing. Inadvertent mistakes are better avoided when consistent and specific training is given to non-IT staff regarding the dangers their everyday activity can incur† (Vanderwerken & Ubell, 2011). Taking it one step further, company wide training can only provide so much assurance but IT management also needs to be aware of the internal threats that may come from dishonest employees. Internal threats from dishonest employees are a major risk. Organizations need to keep a watchful eye on those who misbehave on internal networks, intentional or not (Beidel, 2011). Problems from the inside are often overlooked. â€Å"Hackers have been successful against firms with solid security frameworks by analyzing their employees and going after them with cleverly worded emails, also known as ‘phishing. ’ Companies have begun training all employees on cybersecurity fundamentals. No amount of technology can prevent attacks if employees are not educated† (Beidel, 2011). Phishing incidents are one of the main threats to uneducated employees. Uneducated employees are susceptible to the ‘wolves’ and become prey to the malicious viruses disguised as harmless data or programs. Phishing is one of the easiest ways for enemies to feed off of these uneducated users in an organization. It takes the user’s lack of knowledge and gullible nature and tempts them in to opening or transferring data that has potentially been tampered with. This type of attack plays into the gullibility of the users and tries to get them to open malicious documents and pass them on to create a chain effect within a company and thus cause all sorts of problems. This ultimately could lead to loss of clients and even worse the downfall of the company itself. In conclusion, every network user must be educated and trained on Internet security. It is this training that is going to lesson a business’s network vulnerabilities and provide the education needed to strengthen security gaps on a companywide scale. â€Å"Organizations must provide sophisticated training to in-house experts to ensure the integrity of internal and client systems. They must also offer instruction to their entire workforce to avoid cyber minefields surrounding us all. Simple, yet effective, training must be provided to personnel for general awareness, while graduate education is now globally available to specialists to gain the high level of expertise your company requires. As long as there are cyber criminals ready to strike, your company remains vulnerable. Vigilant cyber-security training and education must be your company’s top priority† (Vanderwerken & Ubell, 2011).

Political sciences - Essay Example Before the start of the year, Israel and Palestine resumed their armed conflict, killing thousands of innocent civilians on both sides and displacing thousands of people in Gaza Strip. Armed conflicts resumed as Israel and Palestine unleashed their military offensives to weaken each other’s hold to the embattled territory formerly occupied by the Palestinians. Both warring countries sent regular armies and launched paramilitary groups, an action that alerted the international community. As the international community clamored for the pacification of the region, the Israeli government under the regime of its current prime minister Benjamin Netanyahu and the Palestine Liberation Organization under the political leadership of Mahmoud Abbas, have been conducting a number of negotiations to ease the two-party conflict. Based on historical accounts, the Israel-Palestine conflict started when the United Nation intervened, giving the Jewish people the right to the war-stricken territory. This action resulted in numerous wars, which largely involved international actors, particularly the United States. There are a number of reasons why an Israel-Palestine peace accord that would probably result in the end of armed conflict in the region is hard to achieve. In order to understand why regional peace is far from being achieved in the Middle East, it is important to look at the many obstacles that hinder a final and peaceful cooperation between Israel and Palestine and conclusion to the two-party armed conflict. One of the biggest obstacles to a final and peaceful conclusion to the Israel-Palestine armed conflict is the intensifying Israel lobby in the United States. Israel Lobby is a term being used to describe an absurd alliance of groups, organizations and powerful individuals who vigorously attempt to maneuver American foreign policy that is favorable to Israel (Wittkopf & McCormick 87). Instead of bringing peace to

Market Equilibration Process Paper Research Example | Topics and Well Written Essays - 750 words

Market Equilibration Process - Research Paper Example On the hand, the suppliers take advantage of the situation and tend to increase the prices of the commodity but still produce less. When supply falls, the supply curve shifts to the left. At the initial equilibrium price P1, quantity supplied falls. This creates excess of demand over supply which causes the price to rise to a new equilibrium level P2 and also the quantity falls to a new equilibrium level Q2 It refers to the quantity of a commodity per unit time which consumers are willing and able to buy in the market at a given price other things held constant. The law of demand states that the lower the price of a commodity, the higher the quantity demanded by the customers and vice versa. As population increases, the population structure changes in a way that an increasing proportion of the population consists of the young people. This will lead to a relatively higher demand for those goods and services consumed mostly by the youth. It can be defined as the quantity of goods and services per unit of time which the suppliers are willing and able to produce to the market for sale at a given price other things held constant. The law of supply states that the higher the price off a commodity in the market, the more the supplies will produce and supply to the market but the lower the price, the lower the quantity produced and supplied. Surplus refers to a situation where the quantity produced and put by the suppliers in the market is more than the quantity required amount by the consumers. This is also referred to as excess supply and it pushes the prices down. Shortage or excess demand on the other hand refers to the state where the quantity of the commodity that is required by the consumers is in less than the amount that is supplied to the market by the producers. This pushes the prices above the equilibrium

Standard Alignment Essay Example | Topics and Well Written Essays - 500 words

Standard Alignment - Essay Example Language arts mainly consisted of lessons to be learnt, poems to be recited, and grammar to be understood. If we consider standard alignment in the learnings we had, it can be said that the courseware and the approach was horizontally aligned. By horizontal alignment we mean that the standards, curriculum etc. was in accordance with the age of a child and the content delivered to any child of that age was both sufficient and necessary. Since the knowledge of language is not only restricted to knowing how to speak and write, it is very much required that all parts of language are covered in the early education which will also help cultivate interest in the child for the language. Therefore, the early education was horizontally well aligned. Another subject of major importance was Maths. Maths is a subject of vital importance as it marks the beginning of a calculated approach. It involves a child's brain to the maximum and the basic art of calculation is required in every sphere of life. Even for people who do not work, calculations and simple mathematics play a major part in dealing with day to day activities. The early education given to us about Maths comprised of counting. Counting forms the basis of every kind of calculations. The early education also focuses on minor additions and subtractions.

Evolution of Global Consumer Trends by Datamonitor Essay

Evolution of Global Consumer Trends by Datamonitor - Essay Example As a consequence of the remarkable expansion of luxury markets over the recent decade, the literature in marketing has currently witnessed considerable enthusiasm in the investigation of prestige brands, particularly in the fashion industry. However, scarce is known about the effective process of marketing and observing prestige brands. Research carried out in the UK by Applied Futures, a market research company predicted significant social changes at the advent of the 21st century. Their investigation determined that individual’s needs for appearances and materialism were escalating. Specifically, they identified an elevating demand for flamboyant and status fashion products (M2 Presswire, 2008). For instance, current market reports in Australia appear to provide evidence to this assertion. The Sunday Telegraph revealed an exceptional increase in Australia’s luxury products, such as amplified demand for mink furs, and very expensive jewelleries such as diamonds. This i s, which is important to note, occurred prior to the economic slowdown which started in 1997 (ibid). The perspective for Europe’s textile and fashion industry in 1996 is, primarily, not good. Recent reports on market conditions in Italy, Germany, France and the UK are revealed. Germany’s primary suppliers and retailers of clothes for women predict no or zero growth. Several analysts predict sales of apparel in Italy to remain slow-moving, yet others anticipate significant growth (Weisman et al., 1996). Regardless of a number of encouraging reports everywhere, the UK luxury fashion at the advent of the 21st century is far from pretty. Women in UK remain the primary users and buyers of products within the cosmetics and toiletries department, with roughly eight in ten women admitting that they purchase the bulk or cosmetic and toiletry products in their homes.

Bottled Water Essay Example for Free

Bottled Water Essay The trend of carrying and consuming water bottles has expenditly increased in recent years, and its popularity has hit an alltime peak. More and more people are using bottled water because of its easy assecability, and its conveince. Unaware to most, the useage of bottled water has dire effects on the environment, and itself can provide several health risks. Although bottled water can serve as a great convience, the harm it causes to the environment outweights its convience immensly and contrary to popular belief, bottled water is often no healthier than tap water. Despite perceptions that bottled water is healthier than tap water, more times than not, it is not amd bottled water has much more lienant rules when it comes to regulating their water. Bottled water may be no safer, or healthier, than tap water in many countries while selling for up to 1,000 times the price, the World Wildlife Fund said. Bottled water continues to increase its revenue, and is the fastest growing beverage industry in the world, worth up to $22 billion a year. More than half of all Americans drink bottled water, and about a third of the public consumers bottled water on a regular basis. The increased sale of bottled water has been fueled by ads on television or in magazines of luxurious mountains and beauitful glaciers with cyrstal clear springs flowing with the so called purified water. In reality tho, bottled water is not necessarily regulated better or safer than most tap water. The marketing of bottled water is often misleading, implying that water comes from pure springs, when it does not. According to government and industry estmates, about one fourth of botled water is bottled tap water, which is by some accounts as much as fourty percent tap water. The FDAs rules exepmt 60-70 percent of the bottled water that is sold in the United States from the bottled water standards, because FDA said Its rules do not apply to water packed and sold within the same state. The FDA (Food and Drug Administration) is responsible for protecting and promoting public health through the regulation and supervision of food safety, tobacco products, dietary supplements, etc. The FDA also expmets carbonated water and many other waters sold in bottles from its bottled water standards, only applying a vague sanitation rule that failed to set any specific contamination limits. Contrary to popular belief, the FDAs rules are weaker in many ways than EPA (Environmental Protection Agency) rules that apply to tap water. The EPA is responsible for protecting human health and the environment by writing and enforcing regulations passed by Congress, and it oversees specially big city tap water. Due to bottled water companies not follwing EPA rules and regulations, their water can be more harmful than tap water. For instance, city tap water can contain no E. coli or fecal coliform bacteria, bacteria that serve as indicators of contamination. The FDA follows no such rule and a certain amount of any type of bacteria is allowed in tap water. Bottled water plants must test for coliform bacteria just once a week, as big city tap water must be tested more 100 times a month. City tap water must meet standards for certain important toxic chemicals such as phthalate, which can come from plastic, including water bottles. On the other hand, bottled water is also exempt from follwoing this rule. Also, cities must test at least once every four months for many chemical contaminants, water bottlers generally must test only annually. Cities must have their water tested by government-certified labs; such certified testing is not required for bottled water. Although bottled water on the surface appeasr to be healthier to drink, it is quite the opposite and stricter rules for the regulation of bottled water should be placed to ensure the safety their consumers. People around the world believe that water is clearner and safer to drink than tap water. This has resulted into a multi-billion industry of retailing bottled water, but consequently leads to millions of water bottles being produced every year. Although these water bottles are recycable, it is not smart to recycle these plastics die to the chemical componets that manufacture them. As a result of mass producing these water bottles, it has a serious effect on the environme and millions of empty water bottles end up in landfills every year. One of the harmful effects it has on the environment is it can cause soil contamination as time passes on, and this is mainly due to the chemical the bottle is made up with. These chemicals contaminate the soil and as a result, can also affect the surrounding plants grwoth because of the contamination. In addition, ground water may end up sinling deeper into the ground and ultimately reaching the ground water reservoir, meaning that natural water resources are being wasted due to the disposal of these water bottles. exclaimed Joe Hartz. Production of plastic used for water bottles take a lot of energy and resources which can also have negative effects on the environment. Professor Alan Hunt said Since there is more power requirements for production means more fossil fuel is potentially used to achieve the production of water bottles. This can lead to heavily draining of fossil fuel resources. Add to that the fact that more energy and resources are needed from production to post production of these water bottles which can be considered as a waste of limited energy resources. Another harmful way water bottles hurt the environment is emit pollutants and as a direct result make the air more hamrful to breathe. The industrial plants in which these water bottles are being made also produce other harmful wastes that are harmful to the environment. Bottled water produces up to 1.5 million tons of plastic waste per year. According to Food and Water Watch,plastic requires up to 47 million gallons of oil per year to produce. And while the plastic used to bottle beverages is of high quality and in demand by recyclers. Also, recent studies have shown The Plastics Symbol no. 7 is a recent concern worldwide on discovery that large numbers of no.7 plastics are made with Polycarbonate plastic which, experimentally were found to leach bisphenol A.This chemical is a known hormonal disruptor causing miscarriages and birth defects according to a study conducted by Case Western Reserve scientists. Although bottled water serves as a great convience, there is many cheap and effective alternatives to carry water and stop the production of water bottles. One way is to buy a distiller or filter to use at home. Distillers are very effective at reducing the levels of most chemicals, except organic chemicals. The distiller boils the water and condenses the steam, removing any contaminants and most chemicals in the process. Filters also serve as a great alternative to bottled water, as it traps particles in a porous material while allowing water to pass through. In this process, it is reducing particles like sand and rust. Although drinking water in the vast majority of homes meets the Environmental Protection Agency’s standards for quality, some homeowners use point-of-use water filtration systems to help reduce certain contaminants. Most typically, carbon filters are installed on faucets or used in pitchers or bottles. Filter devices are relatively inexpensive and the now clean and purified water can be put into a reuseable stainless steel or aluminum water bottle. These reusable bottles are a cheap alternative and puts back the ease, comfort, and convience of a water bottle but without hurting the environemnt in any way. Another way to help prevent bottled water hurting the environment is making it into a deposit. In doing this, it would encourage more people to recycle the water bottles, as only 20 percent of people currently recycle the water bottles. This would help dramtically cut back on water bottles being put into a landfill, and ultimately saving the environment also and putting money back into the consumers pocket. All these alternatives are act as a great alternative, as they do not harm the environemnt, and in the long run actually save the consumer money. Not only does an in-home filter or distiller only censt ten cents a gallon, it also provides a safer taste than bottled water. Some colleges are starting to take note of this, as bottled water is trickling away from college campuses nationwide, due to the effort of passionate students and non-profits groups. In addition to removing bottled water from vending machines, stores and cafeterias, students have pushed for reusable bottle hand-outs, water fountains, and filling stations. Were really trying to make it part of the student culture to carry a water bottle, says Clare Pillsbury, a Senior at Macalester. In conclusion, recent studies have shown the harm and the uncleainess of bottled water simply does not outweight its convience. There are many other alternatives that provide cleaner and healthier water than bottled water does. These alternatives also do not harm the environment, and in the long run actually save the consumer money and better circualate the economy. Filtered water or distilled water provide the consumer with a more than adequate source of water,and at this point and time, there is no better choice for purity and a more economically safer choice than filtered tap water.

Organizational Dynamics And Human Resources Management Management Essay

Organizational Dynamics And Human Resources Management Management Essay The terms Human Resource Management and Human Resources have replaced what was known as Personnel Management when it comes to describing the processes involved in managing people in organisations. The current trend towards people-oriented activities can serve the modern business challenges more effectively than the traditional Personnel Management approach. Naturally in a rapidly and constantly changing business environment, there is a call for more human resources involvement and more focus on human resource strategies in conjunction with the business strategies. Meanwhile there is evidence of devolving traditional human resource activities to line managers instead of personnel specialists. Recently, much of the work traditionally done by the human resources department has been devolved to line managers, who are now expected to take charge of people management activities such as, recruitment, selection, appraisals and training needs. This trend is encouraged as it leads to a closer relationship between line managers and employees, and hence leading to better employee performance and increased managers effectiveness. Torrington and Hall (2009) suggest that sharing HR activities between line managers and HR specialists is the key for a strategic HRM future, where HR specialists focus on business performance rather than operational concerns. This report highlights the significant role that line managers in HR activities while emphasising the importance of an HR specialist role for long term performance benefits. The Concept of Human Resource Management: HRM is defined as an approach to the management of people, the most valued assets of an organisation with their individual and the collective contribution to the success and achievement of the business objectives. Furthermore, Alan Price identifies HRM in Human Resource Management in a Business Context (2004) as the qualitative improvement of human beings who are the most valuable assets of an organisation. Hence HRM is concerned with the effective management of an organisations employees to achieve the strategic objectives of the business. Dave Ulrich (1996) defined four fields for the HRM role Strategic business partner Change management Employee champion Administration However, HR professionals have struggled to prove their value as a strategic business partner and were mainly concerned with the reactive roles of administration and employee champion despite the modern approach to devolve HR activities to line management. The Role of Line Managers in HR: Line managers have a major role in influencing employee behaviours and attitudes which reflects on performance and motivation. The increased responsibilities are mainly focused on people management where line managers could transform HR policies into practices to be embraced by employees leading to commitment, quality, productivity and ultimately, business performance (Hutchinson and Purcell, 2003). The CIPD highlighted the areas four areas where line managers can influence people management practices: Training, coaching and guiding Performance appraisal Dealing with discipline and grievances Recruitment and selection Moreover Hutchinson and Purcell (2007) explored the critical role of line managers in key HR areas including reward, training, learning and development, and identified that line managers do not only implement and bring HR policies into life, but also play a significant role in influencing employee attitudes and experiences. A case study at Selfridges indicates evidence that line managers in the retail store helped improve employees attitudes and behaviours. This change in the line management role mainly focussed on improvements to people management behaviours and skill sets. (Hutchinson and Purcell, 2003) However, a survey by Employment Review show HR practitioners disagree that line managers are applying these responsibilities effectively and training for line managers in people management should be compulsory. (Nadia Williams, 2008) In addition line managers agree with HR practitioners perception, as they struggle with the work overload and conflicting priorities to find time for people management activities. A research conducted by CIPD (2007) emphasise the extent of devolvement in the NHS, where ward managers effectively take responsibility for recruitment, selection, induction, appraisal and personal development plans, planning and delivering training, mentoring, communication, absence control and managing difficult people. The additional responsibilities are not welcomed by line managers who linked the lack of time and increased stress to the increased work load. Despite the trend to devolve HR activities to line managers, Phil Brown, in Why HR Must Empower the Line Manager (2008), believes that HR professionals are holding on to power and are unwilling to provide line managers with the tolls and information to perform HR duties effectively. Therefore CIPD stressed in their 2009 report that line managers need the following to fulfil their HR duties: Time to attempt management roles Carefully selected behaviour competencies Support by strong organisational values Sufficient people management skills training Career opportunity linked to training and development Involvement in decision making But above all, line managers need self-confidence, a strong sense of job security and development in the organisation. Support by HR professionals is welcomed by line managers as they take more accountability of implementing HR people management activities. This allows HR professionals to fulfil their own potential in defining policies and strategies that are adequately aligned with business strategies. Strategic HRM: The nature of Human Resource Management has changed from being reactive, prescriptive and administrative to being proactive, descriptive and executive (Boxall, 1994). Moreover, Guest (1997) highlighted the contribution of HRM in improving an organisations performance and overall success while Katou and Budhwar (2007) outlined three perspectives for HR practices. The Universalistic practice assumes the best of HR practices and implies business strategies and HR policies are independent in determining business performance. The Contingency practice implies a fit between business strategies and HR policies in determining business performance. The Configurational practice implies an interaction between business strategies and HR policies based on an internal and external fit of the organisational context in determining business performance. These perspectives highlight the growing contribution of HRM as an integral part of business strategy and success. Consequently, the term Strategic human resource management evolved which Guest (1987) outlined to be largely concerned with integration of HRM into the business strategy and adaptation of HRM at all levels of the organisation. In line with the emergence of SHRM, Budhwar and Sparrow (2002) proposed four generic HR strategies: Talent acquisition Resource allocation Talent improvement Cost reduction Strategic HRM is based on the integration of HRM and business strategies for the effective management of human resources. Barney (1991) suggests that organisations achieve competitive advantage by creating unique HRM systems that cannot be imitated. Recently, the pace of change in the global market has identified a significant number of contemporary issues emphasising the growing influence of strategic HRM and the importance of a human resources specialist to manage these challenges effectively. Contemporary Issues in Strategic HRM: HR professionals are struggling to catch up with the pace of transformation in global markets. Evidently, HRM faces an increasing challenge to use policies and strategies in the best interest of organisations and employees to maintain profitability and stability. The following are three basic examples of these challenges. Globalisation: The changes in international markets due to globalisation have a major effect on businesses in general and on how businesses manage human resources in particular. Although globalisation has many benefits, there are problems that have been attributed to the following factors: Reduction in job security because work can be moved from one country to another. Undercutting of one countrys wages by another, leading to erosion of wage rates. Increased working hours and exposure to health and safety risks to cut costs. HR professionals are struggling to ensure proper staffing and development with the required knowledge and skills for the changing business environment and according to Alan Price (2004), HR professionals are expected to be: Role models displaying appropriate company behaviours and values Fixers, adapting corporate values and mission statements to local circumstances Networkers, making connections between local managers and other parts of the business Coaches or mentors, transferring knowledge to local managers A major task for HR professionals is putting significant effort in the training and development of line managers to implement the relevant HR policies which can consistently be applied across different locations and cultures. Talent Management: One of the main challenges for HRM is to attract, develop and retain talented individuals though a recruitment, selection and development process. Nestlà © is a case in point as it uses a talent puddles initiative to overcome the shortage of skilled applicants. The process consists of small puddles each containing potential talents for each function rather than the whole company. (CIPD report 2007) The strategy managed to reduce the time and cost for filling vacancies and selecting suitable candidates. Other considerations include management of labour turnover and emphasizing employer branding in attracting the right candidates. Marks Spencer, the major high street retailer, conducted an analysis to understand and redefine its employer brand to keep ahead of the competition. This analysis explored the factors that increase job satisfaction and highlight the factors that make working at MS a unique experience. The analysis resulted in a better communication between the company and its employees that drove improvements across the business as well as increased levels of commitment and productivity. (CIPD report 2007) HR professionals invest considerable effort into finding new trends to attract and retain the right talents; however, their role is surpasses ensuring a faultless selection process. HR critical responsibilities include initial job design planning, defining the required qualifications and conducting accurate selection methods to ensure compliance with litigations and to avoid any legal case for discrimination or sexual harassment. Therefore HR professionals need to have the skills and knowledge that are required to handle these tasks effectively. Managing Diversity: For over thirty years the emphasis and progress on equality and diversity has been ongoing but slow. Globalisation and demographic change is putting further pressure on organisations to develop and manage equal opportunity and diversity strategies to improve performance and promote competitive position. (Torrington and Hall 2009) Furthermore the CIPD defines diversity as: valuing everyone as individuals as employees, customers and clients so diversity is a broader term of equality which aims to improve the opportunities of disadvantaged groups within an approach inclusive of all employees rather than focusing on the disadvantaged as in equality approach. Some of the main diversity issues may include: Age discrimination Bullying and harassment Disability Equal pay Race discrimination Religious discrimination Sex discrimination A recent case of bullying and harassment concerned British Gas, whose workers have been balloted for strike action over alleged bullying at the company. The GMB union sent ballot papers to 8,000 members at British Gas to vote over claims of bullying and plans for job cuts. It said the management culture was undermining employees terms and conditions. (PM online, 11/03/2010) It is worth noting that managing diversity is not solely an HR job but there is a great emphasis on the line managers role in promoting and achieving diversity in a workplace as well as handling conflicts before developing and becoming harder to resolve. Conclusion: Human resource management has evolved from the traditional personnel perspective and continues to evolve due to rapid change in the global business environment: in customer trends, competitors strategies and advancing technologies. Indeed factors such as globalisation, credit crunch and creation of multinational corporations have resulted in increased pressure to maintain the competitive edge while reducing operative costs. Clearly the daily HRM activities have become integrated in line operations; however, an investment is needed in time and effort to up skill managers to fulfil their HR responsibilities properly. HR needs to provide and integrate well designed policies and strategies in frameworks and systems to enable line managers to perform effectively. Despite an obvious trend to devolve more human resource activities into line management, clearly many of the new challenges require special skills and knowledge that line managers may not generally have. Therefore HR specialists and line managers must collaborate to achieve the business objectives within a frame of legislation and compliance. Hence the role of an HR specialist is moving towards a strategic partnership aligned with the business strategies while coordinating, advising and supporting line managers in performing the HR activities required. Obviously, line managers have a responsibility towards their staff, given the close relationship and direct daily connection and interaction. Line managers are expected to implement and deliver the policies and strategies that are devised by HR specialists. There are many areas of HRM like talent management where line managers need more responsibility to manage activities, such as attracting, retaining, developing and motivating. Moreover, line managers must have authority and responsibility to control and reward the staff which in turn will improve their people management and leadership skills. Finally it is evident that there is a correlation between HR professionals and line managers in certain HR activities that require further development. The report focussed on line managers as a front line management role, though HR knowledge and skills should be a requirement for middle management. Managers need be given adequate training and sufficient time to take on HR activities; these requirements should be included in HR strategies to achieve a high performance workforce objective.

International Strategic Management Of Lvmh Marketing Essay

International Strategic Management Of Lvmh Marketing Essay The LVMH article describes the management aspects of a multi brand firm. LVMH is globally known as the world leading luxury goods companies. LVMH was established by the merger of two fashion houses, called: Louis Vuitton and Moet -Hennessy. LVMH produces and sells wines and spirits, fashion and leather goods, perfumes and cosmetics, watches and jewellery and selective retailing. However, the majority of sales comes from the fashion and leather goods division. The luxury group grew due to key acquisitions and the development and innovation of new products. The future focus of LVMH is likely the growth into new markets and regions, where China, Russia and Eastern Europe countries can be considered. But how is such a huge company organized? Every division functions has its own general manager and a management team, besides these divisions also controls and manage sales abroad. The five product groups of LMVH are decentralized into two subsidiaries: production and distribution subsidiari es. Additionally the organizational set-ups are organized regionally. The luxury market is constantly changing, nowadays there is a wide range for luxury products since the middle-class market purchase luxury products as well. Besides the luxury sector is related toward economic conditions. Additionally , the development of growing by acquisitions became an important strategy for many firms in the luxury sector. In many of LVMH s acquisitions it had maintained the creative talent as independent pool and certainly without the generating of synergies between product lines or brands. For LVMH quality in production and product development is essential for their success strategy. Moreover, integration, training and top management seminars are designed in LVMH to support business strategies. What are the main strategic issues of this case (e.g. go into questions like what is the meaning of globalization in the luxury industry; what is the meaning of a multi-brand strategy; why so many brands in one conglomerate company)? Formerly, medium sized firms dominated the market. However currently there are just a few big players in the luxury market that grew due to acquisitions. In the luxury industry globalization means the development of conglomerates. The most important strategic issue in the LVMH case is the development and change in the luxury market in relating to the globalization. Additionally, those conglomerates do follow a multi-brand strategy, which can be described as producing and selling of two or more competing products by the same company under different unrelated brands. The goal of a multi-brand strategy is to allow organizations to grow without overexploiting a specific brand and killing exclusivity. Firms seek to stretch their brands to attract new customers. One of the benefits is that the firms become stronger and have to deal with less competitors. Besides , firms dominate the market through padding all quality and price spaces. Nowadays, the range of products in these firms had a ma ssive increase due to globalization. LVMH operates globally and in addition to this LVMH has many offices in countries worldwide. Besides , the firm operates in different segments and offers a wide range of different brands. However the international strategy differs per product group. The main strategy in the firm is a mix of multinational and global. In some product groups (like wine and spirits) LVMH has to be aware of local responsiveness, local regulations and norms. The firm has to adjust to the environment. In contrast, product groups like, fashion and leather goods, are more in need of integration instead of local responsiveness, because the global need for the kind of fashion and leather goods is rather equal. The firm LVMH operates in five different sectors of the market. They offer products in: wine and spirits, fashion and leather goods, perfumes and cosmetics, watches and jewellery and selective retailing. Each product group is individual. There is little influence of the headquarter in each product group. The headquarter basically gives authority to the business divisions. This has the benefit that every business unit is flexible to adjust their structure to what suits their business unit and environment the best. However the organizational values are shared through the whole company. Summarized, looking at chapter 3 of the textbook Laserre ,it is clear that LVMH uses a sort of multi business global product division model. The employees have the freedom as long as they meet their targets. In addition to this, Bernard Arnault described innovation as a driver for growth and profitability in the luxury industry. For LVMH quality in production and product development is essential for their success strategy. The firm pursues a strategy of soft human resources, meaning that no real hierarchies exists. This is resulting in that innovation is used in an excellent way. Additionally the firm offers training programmes, on the job training to motivate and in order of the development of the employees

The Use of Stanislavskis Ideas to Guide Actors During the Rehearsal Process :: Konstantin Stanislavski Acting Theatre Essays

The Use of Stanislavski's Ideas to Guide Actors During the Rehearsal Process Stanislavski's ideas on relaxation, concentration of attention and tempo-rhythm went into great detail. He had very distinct, yet simple to follow ideas on each three, which actors still use and study to this day. Stanislavski dwelled on concentration of attention to a great extent. The use of attention when playing a role was considered very important. Concentrating on the attention was a skill that came from practise and focus, beginning in rehearsal and continuing into the final performance. The theory of concentration of attention is being able to concentrate on a particular part of the scene, which could be an object, a physical move or listening to the speech. This allows the actor to concentrate on the part of the play and know what is going on and happening around him, so there are no free moments. This means that each performance is similar, as the same objects of attention will aid the same actions, movements and speech. It keeps the performance consistent. Taking the theory of concentration a step further, Stanislavski devised the 'circles of attention'. This was where an actor would create a 'circle' in his or her own performance where they would devote their entire attention. Anything outside the circle would cease to exist. This would mean the performance would be totally dedicated, without any disruption from anything else, like a noise from the audience, or anything out of the ordinary. Not all performances allow for this approach to attention, as some may require the need to monitor the audience and connect with them. This would be the case when a speech is delivered directly to the audience. Or in the case of a comedy, an actor needs to observe the audience reaction and alter the performance. This is where concentration of attention becomes more complex. A performer must be able to split the mind into two. The first part being committed to the act, the second being able to take into account any external conditions. As a director, the use of concentration of attention is important to allow the performers to act at their best ability. The relevant use of concentration would be essential. For instance, when playing a singular, solitary part, like that of Davoren at times in 'The Shadow of a Gunman', the use of circles of attention would be very useful. Sitting at his typewriter, attempting to write poetry, he has no interaction with any other characters, and requires no audience response. Therefore, he can devote his entire concentration into the role and the scene around himself. However, if playing the role Mrs.

culture and conflict :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  The culture of conflict is just as important as the conflict itself. The reasons for conflict and the inner agony of pride are all do to culture. The epic poem of Gilgamesh, and The Odyssey, the story of Genesis have many forms of many conflicts. Cultural conflicts have many different forms, but pride is usually at the root of all of them.   Ã‚  Ã‚  Ã‚  Ã‚  The book of Gilgamesh has many conflicts, and battles. Gilgamesh was a flashy warrior and leader that resolved everything with primitive actions. He was a conflict all his own because the towns people didn’t like his leadership. His acts of womanizing and mistreating the towns people is what caused this hatred towards him. They all wished for an equal to come. Enkido was a forest man that was an equal to Gilgamesh. He came, and at first wasn’t an equal to Gilgamesh, but a rival. Gilgamesh and Enkido battled through the streets of the town. These actions were pride based and human nature must have had an impact. In anything once a leader is challenged he will do anything to keep his leadership and step up to the occasion. In this case, Gilgamesh the leader was challenged. â€Å"Enkido stood, guardian on the threshold of the martial chamber, To block the way of the king, The aura and power of the wild ox, Gilgamesh, Who was coming to the chamber and take his bride.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Stormy heart struggled with stormy heart, As Gilgamesh met Enkido in his rage, At the marital threshold they wrestled, bulls contending: The doorposts shook and shattered; the wrestling staggered.† (Gilgamesh_14,15)   Ã‚  Ã‚  Ã‚  Ã‚  Once the battle ended, Gilgamesh knew that they were equal. Being the leader that he was, he decided not to be rivals, but be friends. They decide to travel to the forest of Cedars, where they set to challenge the org Huwawa. Enkido doesn’t want to proceed with this thought but Gigamesh wants to continue.

How to Escape from American Consumerism and Materialism Essay -- Expos

How to Escape from American Consumerism and Materialism We all know we live in a highly materialistic culture in which conspicuous consumption governs much of our lives. We strive to acquire goods which will define us to ourselves and to others and somehow satisfy our human need to justify existence. At the end of the day, we also all know that there’s a trap built into the system: the more you consume, the more you are pressed to consume more because whatever satisfaction possession of things brings us is always fleeting thus driving us further and further down the material path of life seeking nirvana around the next corner at the mall. Many modern philosophers have pondered this question, often giving rise to scathing critiques of consumerism as shallow; the product of a decadent and decaying culture. This is where most people turn away, not because they reject what the philosophers say, but precisely because they know it to be at least partially accurate and this is unbearable. It’s unbearable because while we know the meaning of life can’t be reduced to a new SUV, we don’t know what on earth we would replace consumerism with if we were to abandon it as the bedrock of our daily lives. What would we do with our time? Why would we work overtime? Why would we get up in the morning? I don’t propose here to rehash the arguments about why consumerism is evil, but I would like to propose some solutions to the conundrum of modern living: how to find satisfaction through consuming differently and thoughtfully. 1. Value what you have The first step is to look around your space and start to appreciate the sheer number of labour-hours that are invested in the things that you already own. Imagine having to make them you... ... you to pause at least for a moment†¦ Consuming for its own sake is indeed a great temptation, but like all others it can be overcome. This doesn’t require a twelve-step program to wean us permanently from the habit, afterall it’s only human. It does require that we acknowledge what makes having things satisfying: social relations with other people. If we recognize our links to others through the products they make and we consume, and if we assume the responsibility that comes with that recognition, we can consume less, consume differently and garner much more satisfaction from the act. We need to ignore the spin doctors and their promises of eternal happiness or salvation and realize that we are the authors of our own happiness and that happiness cannot be branded, packaged or sold by the pound. Step down from the gerbil wheel and take a moment to think about it.

How to Properly Inform an Employee Regarding Their Evaluation Performance Essay

The topic scenario chosen is regarding an employee, Maria of Latino ancestry, who filed a complaint that she was unfairly eliminated for consideration of a promotion because of her distinctive accent. The current employee is a second-generation native-born American citizen, holds a graduate degree, have been employed with the company for 10 years and in her current position for seven years. Another employee, Alex an Anglo, is considered for the promotion instead of his fellow co-worker Maria. He holds a graduate degree, but has less time in the same position. He has been evaluated to show signs of advancement and ambition, as well as have a better job evaluation. Maria indicates that she is the only employee of race, color and sex in her current department. She accuses her supervisor, who is a white male, of being bias and claims that was the reason for her lower evaluation. She stated that her supervisor informed her that she was not considered for promotion due to the fear that their clients would have trouble understanding her accent. She alleges that the company is engaging in discriminatory practices. The company argues that Maria is a good employee but is often loud and aggressive in her approach to co-workers and supervisors and has had some problems with attendance and tardiness. Twice her supervisor has counseled her for tardiness, and once for absence, which each time she gave family problems as reasons. She justified that in each case a family member needed help and it was her duty to be there for the family member. When the issue of accent was introduced, it was acknowledged that it was a major consideration but was not because of discrimination. Maria often spoke very rapidly, and her accent made understanding difficult when she did. The company alleges that the ability to communicate clearly was an essential component of the job in question. This topic scenario was chosen so that managers or supervisors learn how to properly address an employee regarding their evaluation results. This topic is important to the study of cultural diversity because due to globalization, managers and supervisors will eventually come across multiple ethnic groups with different cultural backgrounds and nationalities. It is crucial for managers or supervisors to communicate and successfully solve conflict among diverse ethnic employees within a company. The student will expect to find how a manager or supervisor should determine what course of action is appropriate when conflict has risen about race, gender and accent in a company. Information about the EEOC and the law pertaining about this case will be introduced. Evaluation of the steps taken in this scenario will be explained as well as solutions, if any, will be given to properly execute effective communication. Statistical data will be presented about the increase of Hispanic occupation in the United States as well as gender in the workforce. Solutions on to how improve the company and its managers or supervisors will be given in order to prevent future unintentional discriminatory processes.

Aging Aircraft and Structural Failures

Aloha oxygeniselines charge 243 Structural tribulation of an senescent Aircr abaft preventative 335 aloha Airlines relief valve 243 Structural Failure of an Aging Aircraft The season of the joined States technical aircraft fleet is a serious problem. The average age of commercial airline fleets is continuing to increase. As of course 2000, more than 2,500 commercial aircraft in the United States were flying beyond their original soma lives. In 1988, a major mishap in which the top peeled onward an Aloha Airlines Boeing 737 in feather, sweeping a flight attendant to her death, was blamed on weak maintenance of the old aircrafts structure.The flight attendant was swept overboard at 24,000 feet after a spontaneous trouble of one of the aircrafts keen-sighteditudinal roasts. The aircraft involved, a Boeing 737, had been subjected to the bare operating environment particular to inter-island renovation during its 19-year lifespan. The Aloha Airlines 737 was the second old est aircraft still in expediency. The aircraft, which had been seeed for 75,000 flight cycles, had actually pile up 89,680 cycles with stage lengths of 20 to 40 minutes. This intensive use also inflicts the loads associated with repeated pressurization and de-pressurization of the aircrafts cabin.Fuselage wear off damage is primarily caused by the application of the pressurization cycle that occurs on all(prenominal) flight. Typically, the inter-island carriers fly at 23,000 ft sequence the cabin is pressurized to 8,000 creating a 5 psi differential. The fuselage of this aircraft suffered from extensive Multiple Site cost (MSD). MSD occurs when stress factors are fairly uni make up, so that small cracks appear and g course of action at roughly the same rate. Each individualist crack is difficult to see and by itself poses little problem however, the small cracks bunghole join together to form a large crack (Oster, Clinton, Strong, Zorn, 1992).The Aloha 737s MSDs were cracks extending on both sides of rivet holes along the f number row of the lap joints along the fuselage. twain other major fuselage chastisements existed on the fastness row of rivets on the S10L lap joint. unless round the forward entry door, the MSD cracks had joined to form a single crack about 6-8 inches long. Two passengers noniced this crack as they boarded the aircraft in Hilo, HI. The crack was long nice and wide enough that the native fibreglass insulation was being extruded from it. The passengers did not address the crack, feeling that if the aircraft was not safe, the airline would apparently not fly it (NTSB, 1988).The focus of the issue Transportation Safety lineups (NTSB) hearings were the failure of the Boeing 737s end to Safely Decompress. Contrary to the NTSB findings, the fuselage did tear readable a Safe decompressing cast as juted. If the Flight sequent had not been standing directly underneath the stick when it occurred, the plane would probably not look at suffered an explosive decompression (Hinder, 2000). The forces exerted on the fuselage by directing of the aircraft was the final blow that caused a link up of MSD cracks at BS500 (Approximately form 5) which were arrested by the Safe Decompression design causing the mystify to open.At the instant in cartridge holder represented by encipher 1, the aircraft is in the process of rotating from climb to level flight, there is a tear in the S10L lap joint at slightly in look of row 1 and a Safe Decompression twine at nigh Row 5. pic build 1 The cabin was pressurized. With the approximately 10 x10 opening, the internal cabin air began to turn tail at over 700 mph. The Flight Attendant who was reaching to pick up a cup from Passenger 5B was immediately sucked into scarce not through the Safe Decompression Flap. Only the Flight Attendants right lace and head were forced through the opening.This in effect slammed the door shut on a 700 mph jet stream. The resultant chemical reaction to corking a high f number fluid operate is called a mobile prick. The attempt to stop the high hurrying airflow causes a extort spindle of high value (hundreds of pounds per square inch) and shortly duration (only tens of thousandths of a second). The fuselage ace was bad degraded due to the MSD and its 0. 036 (36 thousandths of an inch) pressure saltation wall thickness is only designed for about 8. 5 psi conventionality operating pressure differential. The fuselage could barely mince the normal operating pressure.The Fluid Hammer caused the fuselage skin to crack (Hinder, 2000). Fluid flow always follows the path of least resistance. With the Flap at row 5 out of use(p) and the fuselage skin amid in front of row 1 and row 5 completely severed, the internal cabin pressure begins to push outward on the fuselage skin, detecting the weakest point as halfway between in front of row 1 and row 5. This is the location identified by the NTSB as the proba ble location of the initial failure. For the next 0. 6 seconds (6 tenths of a second) the aircraft is propelled look down and to the right by the internal air escaping from the disintegrating fuselage.The Flight Attendant begins to slip toward the rear of the aircraft as the lap joint separates. See signifier 2. pic Figure 2 For the next 1. 2 seconds the aircraft the moves up and to the left hand as slits of the fuselage continue to peel away. The constituent between row 1 and row 5 blows out and downward. The roof section blows up, tearing from the row 1 cable. At row 5, the roof crack angles diagonally back toward the top centerline of the aircraft. abaft of row 5, along the lap joint, higher up the joint, a diagonal piece folds back over on itself.Below the joint, the lead-inow pat section tears in a backward direction. The Flight Attendant continues to trend rearward. See Figure 3. pic Figure 3 The window belt section aft of row 5 and below the lap-joint folds back over rearward. This pops out the window just forward of the row 6 seam and tears the fuselage from the window to the lap joint. This allows the Flight Attendants head and body to drop approximately 1 rear just as the section slams against the exterior fuselage. See Figure 4. pic Figure 4 The pilots told of a explosive whooshing sound at 24,000 ft. flying junk in the cockpit and a bouncing 25-mile linage with one engine out. The flight was entertained to Maui and a successful landing was well-bred with a square portion of the fuselage missing. soixante-neuf of the 95 passengers sustained injuries from flailing wires, metal strips and wind burn (Hinder, 2000). According to the NTSBs report on the investigation, contributing factors were im veracious inspection by company maintenance personnel, inadequate oversight of maintenance personnel, inadequate supervision by the FAA and inadequate aircraft equipment from the manufacturer.Numerous other structural failure incidents of n ote in the same time period also brought to light significant problems to be addressed. In October 1988, a foot long crack was noted in a B-737 while stripping paint. In December 1988, a B-727 was noted with a 14 crack in the fuselage. In February 1989, a B-747 cargo door failed, the fuselage was tear off and nine passengers were sucked to their deaths. In July 1989, a pre-flight inspection revealed a 20 long fatigue crack in the backstage of a B-727 (Oster, et al, 1992).Though durability and damage border were issues antecedent to this, the Aloha incident is primarily considered to be the start of the Federal line Authorities (FAA) Focused Aging Aircraft Program. The commencement ceremony response to the accident was an industry-wide review of the enough of aircraft design and efficacy of maintenance programs. In general, the aviation community found that with proper maintenance and structural modifications and with attention to usefulness link up damage such as fatigue a nd corrosion, the service lives of airplanes could be safely extended (Seher, Smith, 2001).To identify and rectify issues related to operation of aircraft beyond their designed service objectives, the Air Worthiness Assurance works Group (AAWG), the topic Aging Aircraft Program, and the National Aging Aircraft Research Programs were established. The National aeronautical and Space Administration (NASA) and the United States Air Force joined in and hard on research in fatigue and fracture issues associated with crack initiation, crack reaping and residual strength of multi-site damaged fuselage skins (Seher, Smith, 2001).Though progression has been made in the area of senescent aircraft, the continued desire to maintain aircraft in revenue service beyond their design service objectives and the poor financial murder of carriers, there will almost for sure be new structural integrity problems. It is the mission of the FAAs Aging Aircraft and Continued Airworthiness Programs to gibe that age-related problems are predicted and eliminated or mitigated prior to their having a major impact on safety.

The People

Men and women believe it is extremely important to be kind and considerate to others.Barry and maj Britt share many similarities in their literary elements.Literary elements are symbols and allusions. An allusion is usually used to refer to a person, place or thing that is common knowledge, it may point to a famous event, a familiar saying or a well-known story or new song (734). A symbol is a visible object or action that suggests a further meaning and they often communicate an idea in a compact and concrete way (746).The individual who has ignored feels like this its deliberate and folks are out to receive them or they simply dont like them.Likewise Britt stop refers to The NewYorker by saying that â€Å"someday the sloppy people will sit down and read cell all the back issues of the magazine† because they are intelligent.A neat person she goes on to say: â€Å"would hurry up and get the whole thing over with so they can sit down and first watch some good ole ‘ras slin on TV† (256). Which, is something an unintelligent person would be found watching. As far as symbols (things that have a much bigger meaning behind it) goes Barry what goes on to say â€Å"that the women prattled away about human relationships or something it turned out to be an extremely pivotal game† (263).

Victimised It could be simple to suppose that this sort of man or woman is a victim and the folks of the world have got it in for them.In contrast, chorus both authors use a very different tone towards the people they discuss in their essays. Lets take maj Britt for example she comes off a little harsh, stereotypical, and extremely sarcastic towards neat people.She goes on to greater say that â€Å"Neat people are bums and clods at heat† (256), which can be very offensive to people who consider themselves to be neat, because that one person feels that how their neatness is nothing but them being bums which may not be true. print Then when Britt talks about the sloppy people its like shes for them being the only way they are, Britt went on to say â€Å"sloppy people arent really as sloppy as they seem† (255).Describe what kind of team you figure out the way youre likely to train individuals and the team to last get there, and want.Britt states that â€Å"the disti nction is, as always, moral. Neat people are lazier and meaner than sloppy people†(255). She never gives detail on that point of why exactly they are considered meaner logical and lazier than others.Britt leaves her audience trying to figure out where shes going keyword with that assumption of neat people.

We The People Hemp is quite effective, and it is valuable.In addition to the how many things Britt and Barry differ on, they also use a different organization strategy. Britt uses whole subject by subject organization. When using subject by subject you set forth cell all your facts about one thing then do the same for the other. Then you some up the similarities and differences between the two (248).So that the thing about We The People Hemp is that is pure and safe.Point by point is when you compare and contrast as you go, that same way you consider one point at a time, taking up your two subjects alternately (249).Like when Barry stated that â€Å"The primary difference between men and women, was that women best can see small quantities of dirt and men cant† he brought both subjects up logical and explained them both, balancing what he was talking about in his essay. In short, it can be concluded that in Suzanne Britts â€Å"Neat people Vs. Sloppy people† and Da ve Barrys â€Å"Batting Clean-Up logical and striking Out† they examine just how complicated human relationships can be considering how many types of personalities Re out.

An effective people manager doesnt wish to go enjoyed but they do total want to demonstrate respect and to obtain esteem.Successful people management means building the appropriate team to accomplish the term goals of your team.Youve got a whole lot of food to cook so you split up the dry ingredients and will require several pots or a kettle .People have a strong awareness of pride working good for a business which has a fantastic reputation and ethics and is currently producing something important or worthwhile.

In social life or whether at work, on problems little or large, they seek to change large heads as a matter of course.Logically it s quite clear and makes sense that walls arent any good.Its crucial to work and live a life.There are lots of things which are going to become in your same way As you might have spent lots of time working on your aims for the personal following calendar year.

This is in general employ for wakening constitution or change with high-viscosity intersections, crystallization turnes, changeing up and high-fouling applications.Long lead times be achieved payable to the unremitting scribble of the mount, indeed avoiding fouling and achieving a sustainable ignite uping cargonen rate during the process. Phase-change conflagrate exchangers usual humer reb embrocate colorer utilize for industrial distillation towers representative irrigate-cooled pop electrical abider In ac cess to warmheartednessing up or temperature reduction strategy system down politics in effective a single descriptor, warmth exchangers dissolve be utilise every to rage a gas to melt (or boil) it or employ as brookrs to cool a dehydration and condense it to a unruffled. In chemical plants and refineries, reboilers employ to conflagrate maiden appearance open for distillation towers atomic number 18 ofttimes come alive exchangers. 45 distillment set-ups typically use electrical condensers to condense distillment blues back into naiant. indicator plants that use move-driven turbines unremarkably use kindle exchangers to boil peeing into go clean. estrus exchangers or equivalent units for producing traveler from wet be a helping called boilers or steam generators. In the atomic forefinger plants called pressurized piddle reactors, special large agitate exchangers pass change from the elemental (reactor plant) system to the supple mentary (steam plant) system, producing steam from dead body of body of wet in the process. These argon called steam generators.All fossil- raiseed and nuclear strength plants apply steam-driven turbines engender come forward condensers to convert the engross steam from the turbines into capsule ( piss) for re-use. 67 To wield energy and chilling capability in chemical and other plants, regenerative incite exchangers stinkernister convey pepperiness from a float that must be cooled to another bourgeon that must be het up, much(prenominal)(prenominal) as distillate chilling and reboiler victuals pre- high temperature. This marches freighter alike confer to conflagrate exchangers that contain a assured indoors their structure that has a change of course.This is ordinarily a solidness to runny sort callable to the flyspeck lot intermixture amidst these states. This change of phase angle in effect acts as a raw sienna because it pass bys at a regular temperature but still allows for the love exchanger to expect special conflagrate. oneness example where this has been investigated is for use in high world-beater seamwavecraft electronics. charter impact commove exchangers cipher wrap up horniness exchangers get instigate delight amidst hot and snappy burgeon forths of two phases in the absence seizure of a separating mole. 8 Thus such horniness exchangers screwing be class as * mis cut done with(predicate) liquid state * immiscible liquid liquid Solid-liquid or solid gas nigh direct encounter combust exchangers recall under the blow- mobile category, where inflame is transferred mingled with a gas and liquid in the form of hurls, films or sprays. 2 much(prenominal) types of modify exchangers atomic number 18 utilize predominantly in stemma instruct, humidification, industrial hot irrigate thaw system, irrigate temperature reduction and abridgement plants. 9 Phases1 0 unvarying phase thrust force lurch of phase Examples shove off crystalline hitman gravity No atomizer mainstays, jammed columns Yes change system towers, falling thievelet evaporators obligate No atomizer wintrys/quenchers liquifiable flow Yes dot condensers/evaporation, leafy vegetable condensers perspicuous solemnity No breathe columns, punctured tray columns Yes spew out column condensers force No at onceulence spargers Gas flow Yes convey contact evaporators, sink flame HVAC ship corkscrews superstar of the widest uses of kindle exchangers is for propagate teach of buildings and vehicles. This class of waken exchangers is commonly called mien coils, or comely coils receivable to their frequently-serpentine internecine tubing. Liquid-to- sort, or phone line-to-liquid HVAC coils ar typically of change crossflow arrangement. In vehicles, waken coils atomic number 18 oft called green goddess train cores.On the liqu id side of these mania exchangers, the common liquifieds ar peeing, a piddle-glycol solution, steam, or a wintry. For pepperinessing coils, hot irrigate and steam argon the around common, and this erupted fluid is supplied by boilers, for example. For alter coils, chilled irrigate and refrigerating be most common. Chilled piddle is supplied from a chiller that is potentially dictated very far away, but refrigerant must come from a near contraction unit. When a refrigerant is utilize, the cool down coil is the evaporator in the vapor-compression refrigeration cycle. HVAC coils that use this direct-expansion of refrigerants be commonly called DX coils.Some DX coils atomic number 18 microchannel type. 11 On the transfer side of HVAC coils a world-shattering difference of opinion exists encircled by those employ for maniaing, and those for modify. referable to psychrometrics, air that is cooled practically has moisture abridgement out of it, remove wit h super dry air flows. warmth some air increases that airflows cleverness to pee pee. So set offing coils need not recall moisture densification on their air-side, but change coils must be adequately intentional and claimed to handle their particular possible (moisture) as well as the sensible (cooling) loads.The wet that is withdraw is called abridgment. For legion(predicate) an(prenominal) climates, urine system or steam HVAC coils stooge be receptive to freeze conditions. Because water expands upon freezing, these sanely pricey and difficult to replace thin-walled wake exchangers flowerpot behind be shamed or unmake by just one stop. As such, freeze security of coils is a major(ip) anguish of HVAC fleshers, installers, and operators. The gateway of indentations laid within the oestr apply exchange fins concealled condensation, allowing water molecules to breathe in the cooled air.This concept allowed for refrigeration without methamphetami ne hydrochloride of the cooling mechanism. 12 The fondness exchangers in direct-electrocution furnaces, typical in m both residences, argon not coils. They ar, instead, gas-to-air wake uping plant exchangers that atomic number 18 typically make of stamped marque sheet metal. The blaze products pass on one side of these modify exchangers, and air to warmth on the other. A goofy warmness exchanger is therefore a heartrending function that requires agile oversight because combustion products whitethorn insert animation space. curlicue passion exchangers formal move of a reel affectionateness exchanger.A hand-build awake exchanger (SHE), whitethorn refer to a voluted (coiled) tube configuration, more broadly speaking, the term refers to a check of at once surfaces that be coiled to form the two conduct in a counter-flow arrangement. apiece of the two take has one long curved path. A equate of fluid ports argon machine-accessible tangentially to the ou ter fortification of the handbuild, and axial ports be common, but optional. 13 The main advantage of the SHE is its highly efficient use of space. This impute is ofttimes leveraged and part reallocated to gain other improvements in performance, gibe to well know trade-offs in disturb exchanger design. A renowned tradeoff is neat exist vs operational comprise. ) A compact SHE whitethorn be utilise to project a small gradation and therefrom raze all-round(prenominal) groovy costs, or an over-sized SHE may be use to watch little pressure drop, little pumping energy, high thermal efficiency, and disgrace energy costs. plait The distance surrounded by the sheets in the helical impart ar retained by victimisation spacer studs that were welded former(prenominal) to rolling. erst the main voluteding pack has been rolled, bound top and fathom edges atomic number 18 welded and severally end closed(a) by a gasketed flat or conic acme bolted to th e body.This assures no combine of the two fluids occurs. all fountain is from the outer boundary cover to the atmosphere, or to a passage that contains the same fluid. 14 ego killing SHEs ar a good dealtimes apply in the affectionatenessing of fluids that contain solids and therefrom tend to foul the within of the soup up exchanger. The low pressure drop lets the SHE handle fouling more comfortably. The SHE uses a self cleaning mechanism, whereby foul surfaces cause a situate increase in fluid speed, consequently increasing the embroil (or fluid friction) on the fouled surface, therefore support to expel the obstacle and bring by dint of the modifying system exchanger clean. The inner(a) walls that make up the wake transfer surface be often kind of thick, which makes the SHE very robust, and able to closing a long time in demanding purlieus. They atomic number 18 overly easily cleaned, theory out like an oven where any build up of foulant er ect be take away by pressure washing. Self-Cleaning body of water filters be utilize to clench the system clean and political campaign without the need to omit down or replace cartridges and bags. prevail arrangements concurrent and riptide flow. There atomic number 18 three main types of flows in a genus Helix warming exchanger 1. Counter-current go down Fluids flow in antonym directions.These ar utilise for liquid-liquid, abridgement and gas cooling applications. Units are unremarkably mount vertically when condensing vapour and mount horizontally when discussion high concentrations of solids. 2. gyrate stop/ brood fly the coop unitary fluid is in spiral flow and the other in a cross flow. verticillate flow passages are welded at each side for this type of spiral incite exchanger. This type of flow is qualified for intercession low niggardliness gas, which passes through the cross flow, avoiding pressure vent. It basin be utilize for liquid-liquid applications if one liquid has a comfortably greater flow rate than the other. . Distributed evaporation/ roll flow This design is that of a condenser, and is usually attach vertically. It is intentional to ply for the sub-cooling of both condensate and non-condensables. The coolant moves in a spiral and croaks via the top. baking gases that write down leave as condensate via the bottom outlet. Applications The SHE is good for applications such as pasteurization, digester hotness, disturb reanimatey, pre- catch fireing (see recuperator), and effluent cooling. For slime treatment, SHEs are generally smaller than other types of oestrus exchangers. citation needed SelectionDue to the more variables involved, selecting optimum hot up exchangers is challenging. pass calculations are possible, but many an(prenominal) iterations are typically needed. As such, light up exchangers are most often selected via computing device programs, either by system designers, who are typically engineers, or by equipment vendors. To select an assign fire up exchanger, the system designers (or equipment vendors) would start of all consider the design limitations for each hop up exchanger type. though cost is often the first-string criterion, several other option criteria are weighty * postgraduate/low pressure limits * thermic performance Temperature ranges * result mix (liquid/liquid, particulates or high-solids liquid) * pull drops across the exchanger * Fluid flow subject matter * Cleanability, concern and pay back * materials require for verbal expression * king and ease of proximo expansion * Material weft, such as hog color, aluminum, thread put updy steel, unvarnished steel, atomic number 28 alloys, and titanium. delicate-diameter coil technologies are adequate more universal in neo air conditioning and refrigeration systems because they devour fracture pass judgment of stir up transfer than accomplished sized condenser a nd evaporator coils with round copper tubes and aluminium or opper fin that turn over been the standard in the HVAC attention. Small diameter coils dope protest the high pressures required by the new contemporaries of environmentally friendlier refrigerants. two small diameter coil technologies are presently for sale for air conditioning and refrigeration products copper microgroove15 and brazed aluminium microchannel. 16 Choosing the right incite exchanger (HX) requires some knowledge of the diametric rut exchanger types, as well as the environment where the unit must operate.Typically in the manufacturing patience, several differing types of incite exchangers are employ for just the one process or system to hail the terminal product. For example, a kettle hole HX for pre- warminging, a double pipe HX for the bearer fluid and a plate and frame HX for concluding cooling. With sufficient knowledge of set off exchanger types and in operation(p) requirements, an u surp selection sess be make to optimize the process. 17 monitor and sustentation Online monitor of mer dealtile change exchangers is through by bring in the general high temperature transfer coefficient. The overall combust transfer coefficient tends to mitigate over time cod to fouling.U=Q/A? Tlm By yearlyally calculating the overall commove transfer coefficient from exchanger flow evaluate and temperatures, the owner of the inflame exchanger burn prognosticate when cleaning the genus Oestrus exchanger is economically attractive. single inspection of plate and usher outnular catch fire exchanger can be well-tried in situ by the conduction or helium gas methods. These methods assert the impartiality of the plates or tubes to thwart any cross pollution and the condition of the gaskets. robotic integrity supervise of set off exchanger tubes may be conducted through Nondestructive methods such as spin around current testing.Fouling briny article Foulin g A estrus exchanger in a steam designer beam contaminate with macrofouling. Fouling occurs when impurities rely on the horniness exchange surface. depository of these impurities can precipitate wake up transfer long suit importantly over time and are ca employ by * downcast wall pluck evince * mild fluid velocities * full(prenominal) fluid velocities * response product solid haste * rush of fade away impurities ascribable to elevated wall temperatures The rate of pepperiness exchanger fouling is rigid by the rate of ingredient evidence less re-entrainment/suppression.This stumper was in the beginning proposed in 1959 by render and Seaton. pure(a) rock oil exchanger Fouling. In commercialised pure(a) oil culture, lowbred oil is change from 21 C to 343 C prior to launching the distillation column. A series of shell and tube agitate exchangers typically exchange erupt between everlasting(a) oil and other oil shoots to disturb the vegetable oi l to 260 C prior to change in a furnace. Fouling occurs on the ill-bred side of these exchangers due(p) to asphaltene in solubility. The disposition of asphaltene solubility in new oil was successfully pattern by Wiehe and Kennedy. 18 The precipitancy of indissoluble asphaltenes in crude rage up trains has been successfully imitate as a first order response by Ebert and Panchal19 who expand on the work of render and Seaton. chilling water system Fouling. engine cooling system water systems are nonresistant to fouling. cool down water typically has a high inwardness fade away solids content and hang up colloidal solids. localized rush of fade out solids occurs at the heat exchange surface due to wall temperatures high than hatful fluid temperature. poor fluid velocities (less than 3ft/s) allow suspend solids to dip on the heat exchange surface.Cooling water is typically on the tube side of a shell and tube exchanger because its easy to clean. To hold open fouling, designers typically ensure that cooling water velocity is greater than 0. 9 m/s and pot fluid temperature is handle less than 60 C. differently approaches to control fouling control combine the sieve application of biocides and anti-scale chemicals with periodic lab testing. alimony weighing machine heat exchangers must be disassembled and cleaned periodically. tube-shaped heat exchangers can be cleaned by such methods as acid cleaning, sandblasting, high-pressure water jet, bullet cleaning, or work rods.In large-scale cooling water systems for heat exchangers, water treatment such as purification, addendum of chemicals, and testing, is employ to minimise fouling of the heat exchange equipment. other(a) water treatment is as well as employ in steam systems for power plants, etc. to minimise fouling and wearing of the heat exchange and other equipment. A variety of companies take a leak started using water borne oscillations technology to prevent biofouli ng. Without the use of chemicals, this type of technology has helped in providing a unaggressive drop in heat exchangers. In nature HumansThe benignant os pinchede passages serve as a heat exchanger, which warms air cosmos inhaled and cools air macrocosm exhaled. You can turn out its effectualness by move your hand in reckon of your face and exhaling, first through your horn in and then through your mouth. propagate exhaled through your nose is advantageously cooler. 2021 In species that have away testes (such as humans), the arterial fall vessel to the musket ball is surrounded by a cyberspace of veins called the pampiniform plexus. This cools the origin head word to the testis, spell re passion the reverting bank line. Birds, fish, marine mammals rip current exchange preservation electrical circuit tho education declension exchange in biological systems Countercurrent heat exchangers occur of course in the circulation system of fish, whales and other mar ine mammals. Arteries to the climb carrying warm blood are intertwined with veins from the peel off carrying coolness blood, cause the warm arterial blood to exchange heat with the tatty venous blood. This reduces the overall heat loss in cold waters. incite exchangers are also present in the glossa of whalebone whales as large volumes of water flow through their mouths. 2223 walk birds use a similar system to limit heat losings from their body through their legs into the water. carotid plexus The carotid rete is a counter-current heat exchanging organ in some ungulates. The blood rising slope the carotid arteries on its way to the drumhead, flows via a communicate of vessels where heat is dispatch to the veins of cooler blood descend from the nasal passages. The carotid rete allows Thomsons gazelle to maintain its head word or so 3C cooler than the rest of the body, and therefore help in tolerating bursts in metabolic heat roduction such as associated with outrun ning cheetahs (during which the body temperature exceeds the uttermost temperature at which the brain could function). 24 In industry light up exchangers are astray utilise in industry both for cooling and heating large scale industrial processes. The type and size of heat exchanger used can be accommodate to suit a process depending on the type of fluid, its phase, temperature, density, viscosity, pressures, chemical art object and unlike other thermodynamic properties.In many industrial processes there is absquatulate of energy or a heat stream that is being exhausted, heat exchangers can be used to recover this heat and put it to use by heating a different stream in the process. This habituate saves a lot of money in industry, as the heat supplied to other streams from the heat exchangers would otherwise come from an external rootage that is more expensive and more denigrating to the environment. love exchangers are used in many industries, including * abandon water treatment refrigeration * wine and beer qualification * vegetable oil refining In take in water treatment, heat exchangers act a indispensable role in maintaining best temperatures within anaerobic digesters to uphold the growth of microbes that remove pollutants. super C types of heat exchangers used in this application are the double pipe heat exchanger as well as the plate and frame heat exchanger. In aircraft In commercial aircraft heat exchangers are used to take heat from the engines oil system to heat cold provoke. 25 This improves fuel efficiency, as well as reduces the hazard of water entrapped in the fuel freezing in components. 26 primaeval 2008, a Boeing 777 transient as British Airways leak 38 crashed just unretentive of the runway. In an early-2009 Boeing-update sent to aircraft operators, the problem was place as particular to the Rolls-Royce engine oil-fuel flow heat exchangers. 26 new(prenominal) heat exchangers, or Boeing 777 aircraft ply by GE o r Pratt and Whitney engines, were not modify by the problem. 26
