How Serious Is Forest Depletion In Pakistan Environmental Sciences Essay

Pakistan has approximately 4.2 million hour angle covered by woods, which is tantamount to 4.8 per centum of the entire land country ( Government of Pakistan 2003 ) , which is really low when compared with 30 per centum for the universe ( FAO 2001 ) . Entire forests country of different states and districts of Pakistan viz. Sindh, Baluchistan, Punjab, North West Frontier Province ( NWFP ) , Azad Kashmir and Northern countries is 0.92, 0.33, 0.69, 1.21, 0.42, and 0.66 million hour angle severally ( Government of Pakistan 2003 ) . This shows that most of the forest distribution is in northern portion of the state ( 40 per centum of state ‘s entire woods are in NWFP, 15.7 per centum in Northern Areas and 6.5 per centum in Azad Kashmir ) . There is a great assortment of species because of the state ‘s great physiographic and climatic contrasts. The woods of the state are of assorted types such as ( a ) litoral and swamp woods, ( B ) tropical dry deciduous woods, ( degree Cels ius ) tropical thorn woods, ( vitamin D ) sub-tropical broadleaf evergreen woods, ( vitamin E ) sub-tropical pine woods, ( degree Fahrenheit ) Himalayan moist temperate woods, ( g ) Himalayan dry temperate woods, ( H ) sub-alpine woods and ( I ) alpine chaparral. The predominating species are of cone-bearing type ( Ahmed and Mahmood, 1998 ; Qazi 1994 ; Poffenberger 2000 ; Suleri 2002 ) . Forest depletion is one of the most serious environmental issues for Pakistan. Harmonizing to an estimation 39 thousand hectares of woods are disappearing yearly. Between the old ages 1990 and 2000, the deforestation rate in Pakistan was 1.5 % yearly ( FAO, 2005 ) . Harmonizing to the Food and Agriculture Organization of the United Nations, some South and Southeast Asiatic states, including Cambodia, Indonesia, Nepal, Pakistan, the Philippines, and Sri Lanka are losing woods at rates transcending 1.4 per centum per twelvemonth. These are among the highest rates of forest loss in the universe. Within South Asia, the rate of forest depletion is highest in Pakistan, despite intensive support from international giver bureaus and legion planetary and local enterprises for forest preservation, policy preparation, and improved administration. ( Rashid, S. 1993 ) . Timber is a cherished trade good in Pakistan, with monetary values presently twice the universe norm, a map of both deficits in domestic supply and import responsibilities. Therefore, both bets and net incomes are high. Despite assorted steps and policy recommendations to minimise the negative influence of powerful local elites, they continue to be active participants in logging and other commercial activities. ( Shahbaz B, Suleri AQ. 2009 ) The forest shrinking in Pakistan is non merely merely because of the direct causes but besides intercession of other authorities sections for the land of forest section for their intents ; for new lodging strategies and allocation of the land to the workers, for route and railroad and other development undertakings in the state throughout the history. The forest sections maintain an antique forestry statute law and disposal, which presents many loopholes which can be exploited by influential persons – the â€Å" lumber Mafia † – who are depriving lumber from the few staying natural woods. ( Shahbaz B, Suleri AQ. 2009 ) Politicians, contractors and administrative officials tend to organize informal webs that give them unsusceptibility from forest Torahs and a free manus to set about forest operations at their ain discretion. To add fuel to the fire, some unscrupulous elements of the Forest Department have facilitated contractors for hard currency inducements – such as payoffs to the local FD staff for every three-dimensional pes of lumber ( Rashid, 1993 ) . The political economic system of the forestry sector has besides become really clear. In the hierarchy of influence, politicians and the â€Å" lumber Mafia † collude to derive entree to lucrative contracts and grants and therefore exert the most influence on wood policy and determinations ( Shahbaz B, Suleri AQ. 2009 ) . The general absence of political will has encouraged the runners and Mafia to spread out their illegal activities in the lumber trade. ( Rashid, S. 1993 ) This survey intends to concentrate attending on this of import factor behind forest screen shrinking in Pakistan i.e. , the function of province sections and lumber Mafia.LITERATURE REVIEWPakistan is a state with low forest screen ; there are merely 0.03 hour angle of forest per capita compared to the universe norm of one hour angle. With the population turning at 2.6 per centum yearly, the forest country per capita is worsening. The country of public woods can non be expanded and trees grown on private lan d lend well to the state ‘s wood production ; this will increase in the hereafter. During 2000/01, Pakistan imported mush and paper merchandises deserving Rs.7 646 million and exhausted Rs.915 million on wood and lumber imports. Pakistan yearly exports athleticss and furniture goods deserving Rs.2 to 3 billion. ( National Forest Policy Review ) Harmonizing to statistics issued in 2006 by the Ministry of Finance and Economic Affairs, forests cover about 4.22 million hectares in Pakistan, merely 4.8 per centum of the entire land country. However, there is considerable contention over the precise forest country in Pakistan, as different national and international bureaus have published statistics based on different definitions of what comprises a wood. Areas designated as â€Å" forest countries † are simply lands under the administrative control of the provincial wood section. Thus, officially designated woods may be devoid of trees while considerable tree screen may be found in countries Other than the designated woods. ( Shahbaz B, Suleri AQ. 2009 ) After divider of the Indian sub-continent in 1947 the new province of Pakistan was left with a really little forest gift of approximately 7 % 1 of its entire land country. This little forest resource base was even further reduced to less than 5 % after the separation of East-Pakistan in 1972. ( INRMP ) The forestry sector contributes merely 0.3 per centum to the GNP. This excludes the indirect benefits that forests provide. Annual wood production is 3.5 million M3, which satisfies the domestic demand for industrial wood. Forest and related little industries provide employment for more than 500 000 people. Forests and rangelands provide eatage to 90 million caput of farm animal. Forests play a critical function in protecting the water partings of Tarbela and Mangla reservoirs, which are really of import for hydropower coevals and for providing H2O to extensive irrigation webs in the fields of Punjab and Sindh states. Annual harm ensuing from inundations, dirt eroding and siltation of reservoirs is estimated at Rs2.3 billion. ( National Forest Policy Review ) Deforestation is one of the most important planetary environmental jobs. Forms of forest debasement are peculiarly seeable in many parts of Asia and Africa. Harmonizing to the Food and Agriculture Organization of the United Nations, some South and Southeast Asiatic states, including Cambodia, Indonesia, Nepal, Pakistan, the Philippines, and Sri Lanka are losing woods at rates transcending 1.4 per centum per twelvemonth. These are among the highest rates of forest loss in the universe. Within South Asia, the rate of forest depletion is highest in Pakistan, despite intensive support from international giver bureaus and legion planetary and local enterprises for forest preservation, policy preparation, and improved administration. Deforestation ever brings negative effects. In September 1992, Pakistan experienced the worst inundations in the state ‘s history, and the vanished woods in the northern water partings were regarded as one of the chief possible causes. Therefore, the federal authorities imposed a complete prohibition on logging in 1993. But the prohibition did non take into history the state ‘s ain lumber demands, and the prohibition non merely triggered illegal logging at that place, but besides led to smuggling of lumber from Afghanistan into Pakistan, doing extended deforestation in Afghanistan. On October 8, 2005, Pakistan suffered its worst catastrophe in history, when an temblor of 7.6 on the Richter graduated table struck South Asia, doing tremendous devastation in the cragged countries of northwest Pakistan. Massive landslides caused farther loss to the part ‘s dwellers. The landslides occurred largely in the bald hills, whereas topographic points with good wood screen suffe red less devastation. ( Shahbaz B, Suleri AQ. 2009 ) Many accounts sing deforestation in the cragged parts of the subcontinent are offered. Most current among these is the Theory of Himalayan Environmental Degradation [ THED ] . The THED ascribes deteriorating environmental conditions of the Himalaya part to the increasing population force per unit area in the delicate mountain ecological environment. The 2nd statement addresses the wider socioeconomic processes-especially urbanisation of the lowland countries and the corresponding addition in the demand for lumber. This besides includes developmental activities and substructure enlargement in the cragged areas-particularly opening up of antecedently unaccessible woods due to building of roads. Alternatively, another strand of research underscores the political economic system attack to resource debasement. For illustration, research has looked into the rent seeking activities of the communities shacking in/around the woods as a beginning of deforestation25. Failure of the authorities to set up a proper institutional set-up for forest direction has besides been blamed as the cause of forest diminution. ( L. Hassan ) The unhallowed confederation between private wood contractors and forest functionaries taking to illegal logging activities has besides been quoted as one of import ground for forest diminution. ( Knudsen. 1996 ) The demands from forest proprietors, right- and non-right holders for lumber, fire-wood, graze and other non-timber wood green goods for subsistence increased significantly with rapid growing in human population, farm animal and alterations in life manners. Often local demands went beyond legal rights offered by assorted legal classs of the woods and several de facto demands were added, many of them pursued by illegal agencies. The of all time shriveling forest base particularly in the countries where such demands had out-grown disproportionately to the forest resource, created instabilities between sustainable supplies and existent demands for subsistence, income addendums to the local hapless and illegal commercial development by the â€Å" lumber Mafia † . ( INRMP ) Harmonizing to Geiser ( 2000 ) , â€Å" in pattern, forest resources are made unaccessible for the hapless and marginalized subdivisions of the communities, whereas the influential along with members of the timber Mafia consumed these resources at their ain Sweet will. †DISCUSSION AND CONCLUSIONAs figures above show that Pakistan is among those states that have really high deforestation rates. Forests in Pakistan are really diverse in nature and of important importance for the state ‘s economic system and supports. Multitudes of people who live in or around these woods depend for their nutrient, shelter, fuel and other such demands on the woods resources partly or entirely and same is the ground incrimination for development and debasement of woods is put on them. A few others take hapless and unsustainable direction of the woods, deficiency of jurisprudence enforcement, hapless institutional capacity of authorities sections, hapless life conditions and deficiency of installations for locals, unplanned development and other such grounds as possible grounds for the forest debasement in the state. There are besides commercial involvements to function supplies to the lumber market and to fulfill Government grosss from forestry. Alongside there exists a big scale illegal commercial development of woods by the alleged â€Å" lumber Mafia. In this paper I have tried to foreground the function of â€Å" Timber Mafia † in forest development and debasement far beyond the sustainable degree. The complete development of woods is a consequence of utilizing the woods for economic intents and non due to the subsistence patterns of the locals. The economic utilizations when knew no bounds were halted by the authorities policies to restrict the forest development above the sustainable degrees. This prompted the illegal film editing and coming of the Timber Mafia. The term â€Å" Timber Mafia † encompasses the contractors, persons, organisations and even the corrupt authorities establishments who somehow or other by their strong lobbying and graft cut the woods even from the countries where lumber harvest home is non allowed. ( INRMP ) defines timber Mafia as The term â€Å" timber Mafia † is a conversational term used throughout NWFP to measure up a group of people engaged in illegal lumber reaping for commercial intents. This group, in assorted configurations, include local lumber runners, Guzara proprietors, former harvest home contractors, local timber-traders, sawmill proprietors, and – at times – forestry staff and local politicians. The lumber Mafia non merely uses such agencies but besides through buttonholing affects the forest policies that would in turn safeguard their involvements as good. In confederation with the Forest Departments they use the loopholes of the forest policies. Furthermore Law enforcement for wood protection is weak and punishments devised by assorted legal instruments such as the Pakistan Forest Act ( 1927 ) , the Hazara Forest Act ( 1936 ) , provincial wildlife regulations and related Acts of the Apostless are uneffective. In add-on to this, none of the past wood policies identified unsustainable commercial lumber reaping and forest depletion by the powerful â€Å" lumber Mafia † supported by politicians and vested involvements as jobs. With the turning scarceness of lumber in the wider market in Pakistan, lumber monetary values increased quickly and illegal harvest home created an extra load on the woods in NWFP. There were besides such policies like Timber reaping prohibition in NWFP which was an of import policy determination by the authorities with effects for the full forestry sector in the state but it besides gave a roar to the Timber Smugglers who when saw that there is no room for run intoing their demands, they shifted their attending to already war wreck Afghanistan so burden on the woods of was shifted from Pakistan to Afghanistan. Another of import factor in illegal commercial harvest home by lumber Mafia are the wages of forest staff, particularly the field staff in lower ranks. Their wages are so light despite the fact that they were keepers of immense forest wealth. Gangs of illegal lumber bargainers have been so influential, good equipped, nomadic and ready to take hazard of damaging, harming, pain, and even slaying the forest staff, who offer opposition and create barriers and limitations in their manner. By and large, the field staff does non acquire the needed degree of support from the Government in commanding or groking the ill-famed wood wrongdoers. Neither the forest offense instances are adjudicated quickly, nor the penalties awarded by the tribunals are appropriate to their magnitude and earnestness. Furthermore, non merely does the mechanism of monitoring, detection, and describing little forest offenses lack answerability but it besides remains weak in the mechanism employed for big graduated ta ble felling. These are the conditions that affect the morale, professionalism, transparence and efficiency of the forest staff. In weaving up and reasoning the treatment I make note of the failings of our policies and establishments to turn to the Timber Mafia in existent sense in its policies and statute laws. My analysis besides allows me to province that the singular difference in the supply and demand of the lumber in the state should be addressed earnestly. My first observation is on the issue of utilizing the woods for economic intents by the strong and influential in the state who on one manus are involved in policy preparation and on the other they are found to be in complete confederation with the runners who with their cooperation non merely excel the statute laws but besides use the loopholes in the wood policies for their intents. It is besides noteworthy that in the name of the protected woods and other such types locals who used to be keepers of the woods themselves ( as they were determiners of their better supports ) were marginalized and woods were declared reserved and protected and so on so it was a kind of free manus to the runners, lumber Mafia and corrupt politicians who are working the woods to their will. Forests are leased out and given on contract that so called â€Å" Conservation Policies † allow the authorities sections to make so. It has changed the position of the woods from Vital Component of Nature to mere â€Å" Revenue Generators † . Revenue coevals belongings of the lumber has outperformed the other of import maps and belongingss of the woods in Pakistan. Furthermore, though the measure limitations had been imposed on the wood remotion by the community, the province itself was involved in inordinate lumber reaping for the building of camps and railroads and province itself is involved in marginalising and coming into direct struggle with the local communities by striping locals of their due royalties and portion on forest resources. The general absence of political will has encouraged the runners and Mafia to spread out their illegal act ivities in the lumber trade. Local people, if given sufficient powers and province support, can efficaciously battle illegal logging, but a sense of ownership is critical. Better, safe and sustainable direction of forest resources can besides be achieved by beef uping of the administrative and protective capablenesss of Provincial Forest Department and by supplying weaponries, wireless sets and operational vehicles and besides by apportioning magisterial powers on Forest Officers to take prompt awareness of forest offenses.

Martin Luther 95 Theses Essay

The Ninty-Five Theses was written by Martin Luther in 1517 and is broadly regarded as the major catalyst for the Protestant Reformation. Martin Luther was an ambiguous German monk and radiant theologian. Martin Luther started a rebellion against the church’s authority which caused the collapse of religious unity of Christendom. The Roman Catholic Church, centered in Rome, extended its influence into every aspect of European society and culture. Due to the increasing power, wealth, and selfishness, a squall of criticism against the church broke out during the Late Middle Ages. Martin Luther and his Lutherans followers led a revolt against the Roman Catholic Church which helped with the creation of The Ninety-Five Theses. The beginning of the European religious problems came in the fourteenth century, when the King, Pope, and Clergy began to gain massive amounts of power and wealth. The idea of medieval Christendom was a newer concept which is basically a Christian commonwealth led by the papacy. As the church tried to create this Christendom, theorists argued that the church was only a spiritual body and therefore its power did not extend to the political realm. The theorists along with the people said that the state needed no guidance from the papacy and that the clergy was not above secular law. The church was becoming more corrupt by the day, which included: nepotism (appointing ones relative to office), pursuit of personal wealth by the bishops, and sexual indulgence of the clergy. Theologians attacked the churches authority by arguing that the church did not control an individual’s destiny, instead by accepting God’s gift of faith. I think this is a very important move by the theologians, because they are sharing similar beliefs to me. I think my church and preacher are very important but not more important the God. With the advent of Lutheranism, personal faith, rather than adherence to the practices of the church, became central to the religious life of European Protestants. The Protestant Reformation of the sixteenth century ushered in a spiritual revolution that had a great impact on the western world. The starting point for the reformation was Luther’s attack in 1517 on the church’s practice of selling indulgences. The Roman Catholic Church taught hat some people go directly to heaven or hell, while others go to heaven only after spending time in purgatory (a period of expiation necessary for those who have sinned excessively). Later in 1517, a Dominican friar named John Tetzel was selling indulgences in the area near Wittenberg. Luther launched his attack against Tetzel and the selling of indulgences by tacking his Ninety-five Theses to the door of the Wittenberg castle church. Luther’s t heses, or propositions, challenged the entire concept of selling indulgences not only as a fraudulent practice but also as a theologically unsafe postulation. At the heart of Martin Luther’s argument in The Ninety-five Theses was the belief that the individual achieves salvation through central religious feeling, a sense of repentance for sins, and a faith in God’s mercy, and that the church attendance, fasting, pilgrimages, charity, and other works did not earn salvation. The church held that both faith and good works were necessary for salvation. Luther insisted that every individual could discover the meaning of the Bible unaided by the clergy. This again was a contradicting idea of that of the Roman Catholic Church, as they believed only the clergy could read and interpret the Bible properly. I think these early defining ideas from Martin Luther were very powerful. I think a lot of people bought into these theses not only because they were believable, but because they could witness the wrongs that the church were committing. Luther argued that each person could directly and freely receive faith from God. Martin Luther’s ninety-five theses had a major effect on religion and culture in early western civilization. I do not think religion would be like it would today if Martin Luther hadn’t led his Lutherans and present his theses. In the fourteenth century, religion was basically all formed into one, especially in Europe. I think all societies in Europe, were part of the Catholic Church. Religion might not have ever broke apart and became their own version of faith with multiple Gods and ideas, if not for Martin Luther. If Martin Luther did not have the courage to act and speak out against something as important as religion, then Catholics, Baptists, Protestants, and Lutherans might very well be completely different or even nonexistent. I ike how Martin Luther wrote his theses by quoting scriptures and adding facts to support his campaign and show Europeans what they had believed and witnessed for so long, but lacked valor to reform. I think it is very significant for people to know about the ninety-five theses and how it helped change and shape religion in early European culture. I really enjoyed reading and writing about Martin Luther and his reformation because I have a strong belief in freedom of religion. I do not think religion should ever be force on someone, and that it should only be something chosen to participate in.

How Does One Create a Positive Organizational Culture Essay

How Does One Create a Positive Organizational Culture - Essay Example Positive culture has the potential of enhancing and improving the performance of given organization. It is mandatory for any visionary leader of given organization to identify and promote positive principles and conduct. Organizational leaders bear the greatest responsibility of determining the course of culture in their respective organizations. Leaders are the ones to identify, set, operate and promote the good cultures to guide the operations of an organization in a long time. In order to create and promote the positive organizational cultures, leaders need to be ready to make sacrifices and delegate some of their duties to their subordinates. They also need to think broadly and make elaborate consultations to avoid mistakes in making choice of particular organizational cultures. Creation and promotion of positive organizational culture does not happen ones nor in easy way, but relies on various processes of learning and adoption throughout the life of an organization. One of the critical stages in the running of an organization which is capable of shaping organization’s culture is recruitment (Burg & Mann, 2008, p. 7). Effective and well decided recruitment process is one of the tools that can help leaders to ensure positive organizational culture. To achieve this, leaders have to employ employees based on their individuals’ merits and qualification. This aspect will ensure recruitment of highly productive workers who work extra hard to ensure conformity and promotion of the organization’s culture and goals.... hat recruitment based on merit has the invaluable advantage of producing highly disciplined and respectful workers who are ready to engage in team work for the prosperity of the organization as opposed to self gain. More impressing about merit based recruitment ensures that selected workforce exhibit high levels of knowhow in their particular fields and may have appropriate capability to enhance innovation and creativity in the production processes. Creative and innovative production processes have the potential of fostering high job output that will automatically increase the profit margins of an organization. As indicated by Burg and Mann (2008, p. 10), employee orientation is another tool capable of fostering a positive culture when employed by organizational leaders. Employee orientation involves informing the newly recruited employees the code of conduct, rules and regulations governing the given organization and to which every employee must subscribe. To achieve this, organizat ional leaders have to introduce new employees to the existing ones to familiarize employees with each other and build confidence of interaction in the new recruits. This will help new employees to adapt quickly by learning prescribed organizational practices from the older employees (Flatt & Kowalczyk, 2008, p. 30). Dilley and Kleiner (1996, p. 5) do confirm that orientation has the potential of encouraging the spirit of consultation among the individual employees on misunderstood and challenging issues. Employee orientation in the new institution should also involve issuing of booklets exemplifying the accepted codes of conduct. Embedding posters depicting policies and procedures on the walls and notice boards in a given organization is one way of orientating employees to the cultures of

A review of academic research undertaken in relation to Small and Medium Sized Enterprises - Assignment Example 5. The act focused on increasing the enterprises’ production outputs, increasing revenues and profits. 6. Small and medium enterprises reduce London’s Unemployment rate. 7. Small and medium enterprises are either sole proprietorships or partnerships. 8. Small and medium enterprises have less than 250 employees. 9. Small and medium enterprises are profitable business ventures. 10. U.K.’s laissez Faire (free) economy encourages entry into the lucrative small and medium enterprise market. 11. With lower capital investments than corporations, small and medium enterprises are preferred choices. 12. The United Kingdom government must implement the provisions of the 2008 Small Business Act for Europe. 13. The United Kingdom government must help lessen small and medium enterprises loan requirements. 14. The United Kingdom government must ensure small and medium enterprises comply with tax, labour, and environmental protection statutes. 15. Small and medium enterprises si gnificantly contribute to the improvement of the United Kingdom economy. Introduction Many individuals boldly join the risky small and medium enterprise market segment. The market segment is grounded on low capital investments. The market segment reduces the United Kingdom unemployment rate. ... Pederzini insists that the European Union exerted extra efforts to help the small and medium European Union member nations’ business money. With the small capital investments, the small and medium size business entities need additional borrowed funds (Warren, 2008). The borrowed funds will help increase the company’s revenues. With more revenues, the small and medium size companies will generate higher net profits. In addition, the additional loan amounts will help the companies pay for the salaries of additional employees. With more employees hired, the service and product quality and speed will consequently increase. After the successful launch of the 2000 European Charter for Small Enterprises, the European Union leaders launched the equally successful Lisbon Growth and Jobs Strategy in 2005. Next, the European Union leadership focused their attention to helping the small and medium enterprises improve their European Union business prospects (Dallago, 2012). In 2008, the European Union launched the timely Small Business Act for Europe. The act contains three favorable aims. First, the government leaders set the guidelines for the improvement economic environment of the small and medium enterprise players. The improvements will trigger higher revenues. With higher revenues, the enterprises can hire more workers. With more workers, the European Union’s unfavorably high unemployment rate will significantly drop to permissible levels (Dallago, 2012). Second, the act focused on increasing competitiveness among the European Union’s small and medium enterprise players. Increasing competitiveness significantly persuades the competitors to improve the quality of their products and services (Cant, 2009). Improvement of their products and

How does CRM help companies with their customers Term Paper

How does CRM help companies with their customers - Term Paper Example Thus, on the basis of such application of information, the store is able to offer its clientele targeted coupons and additional programs that will motivate its consumers to purchase more products from that store (Connick; Turban, Leidner and McLean). In addition, the customer relationship management is an information industry paradigm intended for software, methodologies and especially the Internet service that facilitates a company to manage customer relationships in a well-organized way (Williams; Turban, Leidner and McLean). This paper will discuss some of the important aspects of customer relationship management and how CRM help companies with their customers. The basic purpose of this research is to assess the potential influence of effective CRM policies, technologies and strategies for building better customer services for any business. Customer Relationship Management Systems In the past, the customers’ data were stored in various remote systems in a variety of functio nal departments, for instance, sales, finance, distribution, and marketing. On the other hand, the emergence of e-commerce created huge amounts of customer data that were not incorporated with the data in the service area of the information system. Thus, the CRM applications were created in an attempt to deal with these issues by offering information and tools to bring a better customer experience and to maximize the time customer value for an organization. Basically, the CRM puts together customers’ data from a variety of corporate departments, evaluate these data, and then offer the results to both customers and employees touch points. In this scenario, a customer touch point can be any method to communicate with the customer for instance, email, telephone or fax (Turban, Leidner and McLean; Stair and Reynolds). However, we will make a mistake if we consider the customer relationship management as simply a software system or solution. Without doubt, customer relationship ma nagement can offer the companies a wide variety of tools and techniques to effectively manage and monitor clients. However, CRM is as well a viewpoint, a strategic method for recognizing the requirements of the organization’s customers. In fact, the effective management of a customer’s requirements directs toward customer satisfaction. In addition, if an organization does not link itself with the trends of always growing marketplace, not expecting and responding to its customers, it fails to survive. In addition, a business is not able to construct preference for a product if its customers’ requirements and desires are not precisely understood and satisfied. In this scenario, in the approved manner implemented CRM solutions can be an influential tool that businesses can utilize to build brand preference, and make their customers happy (SageAsiaPac). The Applications of CRM Systems The majority of CRM applications and service packages exist to help organizations manage the customer relationship process. In fact, salespeople are likely to consider of these computer applications as the be-all and end-all of customer relationship management. On the other hand, customer relationship management has at the present turned into a great deal broader as compared to a computer; actually, it has been present in one form or another

Workplace Romance in the Hospitality Industry Research Paper

Workplace Romance in the Hospitality Industry - Research Paper Example As a result of this constant sharing of working space there remains a high chance of the workers in the hospitality industry getting romantically involved with each other. Every worker spends a considerable amount of the day in his or her office. Above that the workers in the hospitality industry work under stressful conditions like round the day duties and living up to the demands of people of different kinds. As a result seeking supports from co-workers and consequent blooming of romance between them is prevalent trend in this industry. In any office environment the co-workers share a lot of feeling like experiences, interests, fears, setbacks and achievements with each other. Therefore it can be seen that the factors responsible for giving birth to romance are always present in the working environment. The constant sharing of emotions may lead to the development of emotional and romantic leanings on each other. The usual office romance varies from casual flings and affairs to the more serious relationships. In the hospitality industry there are also many instances of sexual harassment between co-workers and the scholars have distinguished the workplace romance from sexual advances. Workplaces romances in have been defined as relationship based on mutual desire and physical attraction between the workers of the same organization. It is also necessary that the people have found each other through the course of their work and the relationship is consensual. For romance between workers separated by hierarchy it is important that the romance spreads beyond the traditional employer employee relationship. Workers from all age group have been found to be associated with workplace romance. However the highest probability of romance between colleagues lies in the age group from 35 to 44. In a survey almost 44% of the interviewee in this age group has admitted to date their co-workers (Pearce, 2010). Some very important points of discussion about workplace romance have been the causes for the development of the romance, the effect of office romance on the peers and environment of the office as well as on the people involved directly and the managerial decision or attitude towards accepting the romance (Odgers, 2004, pp 221-222; Burke, Mattis, 2005 p 153; Sias, 2009, p 140). It will be relevant to mention that many of the organizations have a defined policy on workplace romance though no such references could be found directly for the hospitality industry. It has often been debated whether workplace romance leads to better performance of the employees and also the effect of romance on the other co-workers Reasons and the Consequences of Office Romance According to Fiona M. Wilson (2007) the study of romance in office as a sociological subject started 30 years ago. Such studies were of immense interest for the management who wanted to know the consequence on the organization as a result of romances between the workers. According to Peter Corser (20 11), a person spends a third of their day in their office. Under such a situation the author finds it natural for romance to brew between the co-workers. Moreover it can also be mentioned here that for people working in a team the skills, experiences and the knowledge are very similar. Therefore there is a high chance of people sharing common interests and therefore finding each other attractive. However he has also noted that many organizations have discouraging policies for such romances. The organization has

Chemistry Practice - Bonding energy kinetics Lab Report

Chemistry Practice - Bonding energy kinetics - Lab Report Example The bond is covalent in nature. There is a sharing of electrons between these two atoms, giving rise to a covalent bond. The electronegativity value of H is 2.1 while that of O is 3.5 (Brown, LeMay and Bursten, 1991). There will hence be a distortion of the electron cloud, thus causing the molecule to be polar. The bonding between oxygen and hydrogen is polar covalent in nature. Polar molecules are attracted to a charged rod. In these molecules, the centres of positive and negative charges do not cancel each other out, giving rise to permanent dipoles. When a positive rod is used, the negative end of the dipoles are attracted towards the rod while the positive end of the dipoles are attracted to a negative rod. 3. Using the 'electron pair repulsion theory', state and explain the shape of the following compounds and in each case sketcha diagram to show the arrangemant of the atoms in space, labelling the bond angles. In AlCl3, the three outer electrons of the aluminium atom are bonded to the outer electrons of three chlorine atoms. Since there are no lone pair of electrons, the structure will not be distorted. According to the electron pair replusion theory, the three bonded pairs repel each other as far apart as possible. AlCl3 will hence be trigonal planar in shape with a bond angle of 120 (Brown, LeMay and Bursten, 1991). (b) SiH4 In SiH4, the four outer electrons of the silicon atom are bonded to the outer electrons of four hydrogen atoms. There are no lone pair of electrons. According to the electron pair replusion theory, the four bonded pairs repel each other as far apart as possible. SiH4 will hence be tetrahedral in shape with a bond angle of 109.5. (c) PCl5 In PCl5, the five outer electrons of the phosphorus atom are bonded to the outer electrons of five chlorine atoms. There are no lone pair of electrons. According to the electron pair replusion theory, the five bonded pairs repel each other as far apart as possible. The shape of PCl5 will be trigonal bipyramid, with bond angles of 120 and 90. 12 marks 4.

Corporate Finance - Assignment 01 Example | Topics and Well Written Essays - 1500 words

Corporate Finance - 01 - Assignment Example It was prudent, as the finance manager, to make a transaction decision that had the highest competitive advantage. The decision would be based on the exchange rate for both currencies based on the AED. By monitoring the exchange rate for a period of five days, it was evident that the best decision would be established. In addition, monitoring the exchange rate for both currencies in relation to the AED provided the opportunity to establish the best possible currency to use; the most stable among the two. a) Check the exchange rate for a period of five days and create a table of comparisons of how much will be your AED50m worth on each of the five days in both Euros and GB pounds. Choose the currency you will use for your transactions. Considering the purchasing power parity, the law of one price states that similar goods should have a similar price after taking into account the exchange rate. This is before transportation costs have been incorporated to the cost of bringing the goods to the desired location. In this case, the Great Britain Pound will be used for the transactions because there are minimal deviations in the exchange rate from 24th December to 28th December. In addition, the exchange rate is stable as opposed to the Euro. Purchasing the equipment on the second day would save the company As the finance manager, the option maximizes utility, but at a relatively higher cost compared to the first day of monitoring the exchange rate. Purchasing the equipment on the third day would save the company Contrary to the savings on the first and second day; the third day proves to have AED124 and AED2, 606 more savings respectively. The third day would be the best option because the exchange rate maximizes utility at the lowest cost. Purchasing the equipment on the fifth day would save the company The savings are relatively lower than those on the first and third day. Although the option maximizes utility, it does so but at a

Unlike public libraries, these rarely allow citizens to borrow books. Often, they include numerous rare, valuable, or significant works. National libraries are usually notable for their size, compared to that of other libraries in the same country. Some states which are not independent, but who wish to preserve their particular culture, have established a national library with all the attributes of such institutions, such as legal deposit. Many national libraries cooperate within the National Libraries Section of the International Federation of Library Associations and Institutions (IFLA) to discuss their common tasks, define and promote common standards and carry out projects helping them to fulfil their duties. National libraries of Europe participate in The European Library. This is a service of The Conference of European National Librarians (CENL). 9. 2Academic Library An academic library is a library which serves an institution of higher learning, such as a college or university libraries in secondary and primary schools are called school libraries. These libraries serve two complementary purposes: to support the schools curriculum, and to support the research of the university faculty and students. The support of teaching requires material for class readings, and for student papers. In the past, the material for class readings, intended to supplement lectures as prescribed by the instructor, has been called reserves. In the period before electronic resources became available, the reserves were supplied as actual books or as photocopies of appropriate journal articles. Traditionally, one copy of a book was made available for each 10 students — this is practical for large classes only if paperback copies are available, and the books reused from term to term. Academic libraries must decide what focus they take in collecting materials since no single library can supply everything. When there are particular areas of specialization in academic libraries these are often referred to as niche collections. These collections are often the basis of a special collection department and may include original papers, artwork, and artifacts written or created by a single author or about a specific subject. 9. 3Special Library A special library is a term for a library that is neither an academic nor school library, nor a public library. Special libraries may include law libraries, news libraries, government libraries, corporate libraries, museum libraries, and medical libraries. Special libraries are also sometimes known as information centers. Special libraries often have a more specific clientele than libraries in traditional educational or public settings, and deal with only a specialized or particular type of information. They are developed to support the mission of their sponsoring organization and their collections and services are more targeted and specific to the needs of their clientele. 9. 4School Library A school library or school libraries media center is library within a school where students, staff, and often, parents of a public or school have access to a variety of resources. The goal of the school library media center is to ensure that all members of the school community have equitable access to books and reading, to information, and to information technology. A school library media center a use all types of media is automated, and utilizes the Internet as well as books for information gathering. School libraries are distinct from public libraries because they serve as learner-oriented laboratories which support, extend, and individualize the schools curriculum. A school library serves as the center and coordinating agency for all material used in the school. 9. 5Digital Library A digital library is a library in which collections are stored in digital formats as opposed to print, microform, or other media and accessible by computers. The digital content may be stored locally, or accessed remotely via computer networks. A digital library is a type of information retrieval system. 9. 6Mobile Library A bookmobile or mobile library is a large vehicle designed for use as a library. They are designed to hold books on shelves so that when the vehicle is parked the books can be accessed by readers. They usually have sufficient space that people can also sit and read books inside them. Mobile libraries are often used to provide library services to villages and city suburbs without library buildings. They also service those who have difficulty accessing libraries, with retirement homes being common stops. They may also carry other information or computer equipment, such as might be found in a library. Some libraries also use their bookmobiles to deliver materials, such as audio books and large print novels, to homebound patrons who dont have anyone to go to the library for them. 10. 0PROFESSION * Chief Librarian * Library Director * Senior Librarian * Librarian * Cataloger * Indexer 10. 1Chief Librarian The Chief Librarian shall, on appointment, provide the staff member with a written position description which sets out the general responsibilities of the position held by the staff member. The Supervisor shall assign the specific duties of the staff member, bearing in mind the position description. The supervisor shall also determine, at least annually, performance expectations which shall be appended to the position description. The Chief Librarian may revise the staff members position description following consultation with the incumbent and, if requested by the incumbent, with the Association. The revision shall take into account the qualifications and experience of the incumbent. The Chief Librarian may transfer a staff member to a different position in the University Library and, if so, shall provide the staff member with the position description for the new position. Prior to such transfer, the Chief Librarian shall consult with the incumbent and, if requested by the incumbent, with the Association. 10. 2Library Director Plan and manage all aspects of library operations: budget, personnel, services, program planning, development and assessment, facilities and equipment. Implement university vision through long-range planning. Plan and implement new and enhanced user-services, including information literacy and remote access for populations at off-campus instructional locations. Create library policies in collaboration with library faculty members. Coordinate collection development and management of library collections Collaborate with Office of Information Technology on integration of emerging technologies and provision of electronic resources to the university community. Lead in an open and collaborative manner. Integrate the core values of respect, compassion, integrity, justice and service in all aspects of interaction. 10. 3Senior Librarian Under direction, to supervise and perform a full range of professional services in a major functional area within the library, and to do related work as required. Supervises children’s section of the library; selects books and other media for children and young adults; plans and presents programs, story hours, puppet shows and book talks; teaches children the use of library tools; advises parents on use of library facilities; establishes communication with teachers; reads book reviews and compiles bibliographies; gathers statistics and prepares report; reads relevant literature and reviews; supervises pages; attends and participates in professional meetings. Supervises cataloging of books and other library materials; does original cataloging as required; supervises book process; plans, supervises and reviews the work of cataloging clerk, book processor, and mender; works with other professionals in maintenance of collection and completeness of catalog; compiles monthly and yearly statistical reports; occasionally works at the reference desk; attends and participates in professional meetings; reads relevant literature. 10. 4Librarian. A librarian is an information professional trained in library and information science, which is the organization and management of information services or materials for those with information needs. Typically, librarians work in a public or college library, an elementary or secondary school media center, a library within a business or company, or another information-provision agency like a hospital or law firm. Some librarians are independent entrepreneurs working as information specialists, catalogers, indexers and other professional, specialized capacities. Librarians may be categorized as a public, school, correctional, special, independent or academic librarian. 10. 5Cataloger The cataloger is responsible for original cataloging of monographs and other formats in Slavic and other European languages in all subjects. The Library is a member of the Program for Cooperative Cataloging, and descriptive cataloging is performed in accordance with national standards. Subject analysis and classification assignment follow Library of Congress standards and local practice. Authority records follow NACO standards and are contributed to the national authority file. The cataloger also investigates and participates in implementation of solutions for providing bibliographic control for all types of resources including electronic resources. In addition to cataloging traditional materials and in support of the Catalog Department’s endeavor to integrate bibliographical control for digital resources, the cataloger may participate in activities to implement non-MARC descriptive standards and contribute to the development of new metadata services for the Library’s growing collection of digital resources. The cataloger collaborates with other catalogers and Library staff to establish and maintain local policies and procedures for bibliographic and metadata services, projects, and other activities that affect the library’s integrated library system, search engines, and overall access to the collections. He/she keeps abreast of the current trends and best practices for bibliographic and metadata services in the field. The cataloger also serves on library committees, participates in library-wide programs and activities, and is expected to be active professionally. 10. 6Indexer Search engine indexing collects, parses, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics and computer science. An alternate name for the process in the context of search engines designed to find web pages on the Internet is Web indexing. Popular engines focus on the full-text indexing of online, natural language documents. Media types such as video and audio and graphics are also searchable. Meta search engines reuse the indices of other services and do not store a local index, whereas cache-based search engines permanently store the index along with the corpus. Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Larger services typically perform indexing at a predetermined time interval due to the required time and processing costs, while agent based search engines index in real time. 11. 0CONCLUSION.

A Major Application Area Of Thermodynamics Engineering Essay

A Major Application Area Of Thermodynamics Engineering Essay A major application area of thermodynamics is refrigeration, which is the transfer of heat from lower temperature region to a higher temperature one. The devices that produce refrigeration are called refrigerators, and the cycles on which they operate are called refrigeration cycles. The most frequently used refrigeration cycle is a vapour-compression refrigeration cycle in which the refrigerant is vaporized and compressed alternatively and is compressed in the vapour phase. There are number of refrigerants which can be used in here, but the most commonly used on a commercial scale is a R12 (used in this experiment as well). The thermodynamics of ideal vapour compression cycle can be analyzed on a temperature versus entropy diagram as depicted in Figure 1. At point 1 in the diagram, the circulating refrigerant en- ters the compressor as a saturated vapour. From point 1 to point 2, the vapour is isentropically compressed (i.e., compressed at constant entropy) and exits the compressor as a superheated va- pour. From point 2 to point 3, the superheated vapour travels through part of the condenser which removes the superheat by cooling the vapour. Between point 3 and point 4, the vapour travels through the remainder of the condenser and is condensed into a saturated liquid. The condensation process occurs at essentially constant pressure. Between points 4 and 5, the saturated liquid refrigerant passes through the expansion valve (throttling device) and undergoes an abrupt decrease of pressure. This process results in the adia- batic flash evaporation and auto-refrigeration of a portion of the liquid (typically, less than half of the liquid flashes). The adiabatic flash evaporation process is isenthalpic (i.e., occurs at con- stant enthalpy). Figure 12 Temperature Entropy diagram 1 www. wikipedia.org/wiki/Refrigeration 2 http://upload.wikimedia.org/wikipedia/commons/f/f7/RefrigerationTS.png UMAR DARAZ Page 3 of 22 Thermodynamics Lab 2 Between points 5 and 1, the cold and partially vaporized refrigerant travels through the coil or tubes in the evaporator where it is totally vaporized by the warm air (from the space being refrigerated) that a fan circulates across the coil or tubes in the evaporator. The evaporator operates at essentially constant pressure. The resulting saturated refrigerant vapour returns to the compressor inlet at point 1 to complete the thermodynamic cycle. The area under the process curve on T-s diagram represents the heat transfer for internally reversible processes. The area under the process curve 5-1 represents the heat absorption in the evaporator, the area under the process 2- 4 represents the heat rejection in the condenser. In the ideal vapour compression refrigeration cycle all the heat losses and disruptions are being ignored, but in actual refrigeration cycle, we need to take these losses into consideration as they have been mentioned in this report later. The Hilton refrigeration laboratory unit R714 is capable of following entities;  · Investigation of the variation in refrigerator duty or cooling ability for various condens- ing temperature and the heat delivered to the cooling water with variation in condensing temperature. We can also investigate the variation in refrigeration coefficient of per- formance for the various condensing temperature.  · Investigation of the variation in coefficient of performance based on electrical, shaft and indicated power, determination of the overall heat transfer coefficient for the condenser cooling coil and performance of the thermostatic expansion valve.  · Investigation of the heat delivered to the cooling water with variation in condensing tem- perature, coefficient of performance as a heat pump for various condensing temperature, as well as power input based on electrical, shaft and indicated power. The important aspect of this report is to demonstrate the two laws of thermodynamics i.e. first and second law of thermodynamics. The first law is simply an expression of the conservation of energy principle, and it asserts that energy is thermodynamic property. Qout = Wnet + Qin Equation (1) In this experiment the Qin is provided by input voltage, this input is used to do the net work done on the refrigerant by compressor and motor, and the result of this produces the heat which is being removed by the condenser i.e. Qout. The second law of thermodynamics asserts that energy has quality and quantity, and actual processes occur in the direction of decreasing quality of energy. UMAR DARAZ Page 4 of 22 Thermodynamics Lab 2 Aims and objectives: The Hilton refrigeration laboratory unit R712 has been designed to allow students to fully investigate the performance of a vapour compression cycle under various conditions of evaporator load and condenser pressure. The main objectives of this laboratory are listed below;  · The demonstration of application of the First and second law of thermodynamics.  · The introduction of to refrigeration plant and calculate the various coefficient of perform- ance.  · Investigation of system losses, this includes motor, compressor, evaporator and con- denser losses. These losses (friction, heat losses) occur only in practical/commercial refrigerator, there are no losses in ideal vapour compressor refrigerator. UMAR DARAZ Page 5 of 22 Thermodynamics Lab 2 Apparatus The figure shown below looks like a refrigeration laboratory unit R712 (not exactly it) and it consists of the following components; Figure 23 Refrigeration laboratory unit Panel: High quality glass reinforced plastic on which the following components are mounted. Refrigerant: R12 Digital Thermometer: A device that measures temperature. Wattmeter: Allows measurement of the power input to either evaporator or motor. Voltage Controller: To vary evaporator load. Variable Area Flow meters: Variable area types to indicator R12 and H2O flow rates. Pressure Gauges: To indicate R12 pressure in evaporator and condenser. Spring Balance and Tachometer: These two together allow measurement of power required to drive the compressor. Expansion Valve: Thermostatically controlled type i.e. throttling device. Evaporator: Electrically heated device i.e. heat exchanger Compressor: (Internally mounted) Twin cylinder belt driven unit, along with spring balance force system. Condenser: A device or unit used to condense vapor into liquid. It is also called heat exchanger. Motor: A machine that converts electricity into a mechanical motion. 3 www.p-a-hilton.co.uk/English/Products/ Refrigeration__2_/refrigeration__2_.html UMAR DARAZ Page 6 of 22 Thermodynamics Lab 2 Procedure4 In prior performing an experiment the most important things to do are, to measure the atmos- pheric pressure, which would be added to the gauge pressure to get an absolute pressure for both condenser and evaporator, and to balance the two tips of the spring balance force, being applied on the compressor. In failure to do these things would cause a sufficient amount of error in the final results. In this experiment the condenser pressure is being kept constant i.e. 900KPa. Step-1 Turn on the refrigeration plant using one of the control breakers, and setting the evaporator voltage i.e. 40 100 volts, at the same time balancing the two tips of compressor load and set the condenser pressure to 900KPa, using rota-meter. Step-2 Record the following values; Evaporator Amps (1-2.42A), from wattmeter, compressor speed using tachometer, water and refrigerant flow rate using flow meter. Step-3 Record the spring balance force, reading directly from the scale. The hot water is in the tubes is indicated by red and cold water is indicated by blue sign in the refrigeration plant. Step-4 The flow rate is controlled by a throttling device (valve), the small changes in opening and closing the valve, effect the condenser pressure. Step-5 The temperature values of the refrigerant at different stages in the whole cycle at constant pressure is given by temperature dialler. Now we had all the values we needed, now we changed evaporator Amps value, recorded rest of the values as mentioned earlier and repeated the whole experiment for three to four times. The Refrigeration Laboratory Unit has three controls. Firstly a combined miniature circuit breaker and switch turns on both the compressor motor and the supply to the electrically heated evaporator. A combined variable area water flow meter and valve allow control of the condenser pressure and a panel mounted voltage controller allows control of the evaporator load from zero to full power. Refrigerant R12 vapour is drawn into the compressor from the evaporator mounted on the front of the panel. Work is done on the gas in the compressor and its pressure and temperature are raised. This hot, high pressure gas discharges from the compressor and flows into the panel mounted water cooled condenser, where heat is removed from it. This liquid then flows through a thermostatic expansion valve. Here it passes through a controlled orifice, which allows its pressure to fall from that of the condenser to that of the evaporator. The refrigerant has a satu- rated vapour phase at this point. The voltage across the heater elements may be varied from zero to that of the mains supply voltage by adjustment of a voltage controller situated on the front panel. Measurement of the power is carried out by a panel mounted digital wattmeter. 4 http://www.p-a-hilton.co.uk/R714-Edition-2-GREY.pdf UMAR DARAZ Page 7 of 22 Thermodynamics Lab 2 Results The observation table below shows all the values of different components in the refrigeration plant along with input indices and output indices, enthalpy of the cycle and losses in the system.

Calculations To find absolute pressure, we need an atmospheric and gauge pressure of the component. Now for two individual components,  · Condenser As we know Patm = à Ã‚ gh = 13600 kg/m3 ÃÆ'- 9.81 m/s2 ÃÆ'- 762 ÃÆ'-10-3m = 101.663ÃÆ'-103 Kg / ms2 = 101.663 KN/m2 Hence Pgauge,cond = 900 KN/m2 Pabs,cond = Patm + Pgauge,cond = 101.663 + 900 = 1001.663 KN/m2  · Evaporator As Patm = à Ã‚ gh = 13600 kg/m3 ÃÆ'- 9.81 m/s2 ÃÆ'- 762 ÃÆ'-10-3m = 101.663ÃÆ'-103 Kg / ms2 = 101.663 KN/m2 i. Pgauge,Evap = -20 KN/m2 Pabs,Evap = Patm + Pgauge,Evap Therefore = 101.663 + (-20)= 81.663 KN/m2 ii. Pgauge,Evap = 20 KN/m2 Pabs,Evap = Patm + Pgauge,Evap = 101.663 + (20)= 121.663 KN/m2 iii. Pgauge,Evap = 40 KN/m2 Pabs,Evap = Patm + Pgauge,Evap Therefore = 101.663 + 40 = 141.663 KN/m2 To find Qw (Heat removal from condenser) As we repeated the experiment three times, so water flow rate have three different values, hence we need to find Qw at three points, Qw = Mw ÃÆ'- 4.18 (t6 t5) When Mw = 1.5 gs-1, t6 = 41.2 0C, t5 = 23.8 0C Qw = 1.5 ÃÆ'-4.18 (41.2 23.8) = 109.098 W UMAR DARAZ Page 11 of 22 Thermodynamics Lab 2 As Qw = Mw ÃÆ'- 4.18 (t6 t5) When Mw = 5.0 gs-1, t6 = 39.6 0C, t5 = 21.6 0C So Qw = 5.0 ÃÆ'-4.18 (39.6 21.6) = 376.2 W Qw = Mw ÃÆ'- 4.18 (t6 t5) When Mw = 6.0 gs-1, t6 = 38.5 0C, t5 = 21.4 0C Qw = 6.0 ÃÆ'-4.18 (38.5 21.4) = 428.87 W To find Wc (work done by the compressor or a shaft loss) The work done by the compressor depends on spring balance force and motor speed, hence to get more work done out of the compressor we need to increase any of the above mentioned parameters. Therefore Wc = 0.0172ÃÆ'-FÃÆ'-Nm i. Wc = 0.0172ÃÆ'-5.5ÃÆ'-1512.09 = 143.043 W ii. Wc = 0.0172ÃÆ'-7.5ÃÆ'-1502.58 = 193.832 W iii. Wc = 0.0172ÃÆ'-8.2ÃÆ'-1449.71 = 204.467 W To find Wm (work done by the motor on a shaft to rotate) The work done by the motor is a product of voltage provided, amount of current flowing the motor and power factor of the shaft, which gives us the following values; Wm = Vm ÃÆ'- Im ÃÆ'- pf i. Wm = 235 ÃÆ'- 3.6 ÃÆ'- 0.43 = 363.78 ii. Wm = 232 ÃÆ'- 3.6 ÃÆ'- 0.48 = 400.89 iii. Wm = 232 ÃÆ'- 3.6 ÃÆ'- 0.52 = 434.31 UMAR DARAZ Page 12 of 22 Thermodynamics Lab 2 To find CoPnet (Total coefficient of performance of refrigerant) CoPnet = Qe, Elec / Wm By substituting different values of electric input heat energy (artificial input energy) and the work done by the motor, we get net coefficient of performance of the cycle, i. CoPnet = 40 / 363.78 = 0.109 = 11% ii. CoPnet = 119 / 400.89 = 0.296 = 30% iii. CoPnet = 242 / 434.31 = 0.557 = 56% To find CoP (te-t2) This is the coefficient of performance of ratio of temperature values at point 1-4 and difference of it, to the temperature of the refrigerant after compression, so we get following CoP (te-t2) = t41 / (t2-t41) i. CoP (te-t2) = 13.9 / (69.4 13.9) = 0.250 = 25% ii. CoP (te-t2) = 8.5 / (59.9 8.5) = 0.165 = 16% iii. CoP (te-t2) = 1.0 / (68.5 1.0) = 0.015 = 1.5% To find Qe, R 12(Heat removal from Evaporator) The given equation is à ¢Ã¢â€š ¬Ã‚ ¦ Qe, R 12 = Mr (h1 h4) By substituting different values of enthalpy, which we recorded from a pressure enthalpy diagram, so we get i. Qe, R 12 = 0.7 (340 160) = 126.0 ii. Qe, R 12 = 1.5 (345 170) = 262.5 iii. Qe, R 12 = 1.9 (360 180) = 342.0 UMAR DARAZ Page 13 of 22 Thermodynamics Lab 2 To find Wc (Input work done or compressor work loss) The input work done by the compressor can be calculated by finding flow rate of the refrigerant R12 and the difference of enthalpy of refrigerant before and after the compression. Wc = Mr (h2 h1) Substituting all three values of the above parameters (variables), we get i. Wc = 0.7 (385 340) = 31.5 ii. Wc = 1.5 (400 345) = 82.5 iii. Wc = 1.9 (420 360) = 114 To find Q cond (Heat loss by the condenser) Similarly heat loss by the condenser is a product of refrigerant flow rate to the difference of enthalpy values of it, before entering and leaving the condenser, we get Q cond = Mr (h2 h3) Now, using above stated equationà ¢Ã¢â€š ¬Ã‚ ¦ i. Q cond = 0.7 (385 225) = 112 ii. Q cond = 1.5 (400 240) = 240 iii. Q cond = 1.9 (420 250) = 323 To find CoPR12 (Coefficient of performance of refrigerant) CoP R12 = (h1 h4)/(h2 h1) Coefficient of performance of refrigerant is a ratio of all the enthalpy values in the cycle, here note that for ideal vapour compression refrigeration cycle h3 = h4 Hence we get i. CoP R12 = (340 160) / (385 340) = 4.00 ii. CoP R12 = (345 170) / (400 345) = 3.1818 iii. CoP R12 = (360 180) / (420 360) = 3.00 UMAR DARAZ Page 14 of 22 Thermodynamics Lab 2 Systems losses Motor loss = Wc Wm = 143.043 363.78 = -220.75 = 193.832 400.89 = -207.06 = 204.467 434.31 = -229.84 Compressor loss = Wc-Wc = 31.5 143.043 = -111.54 = 82.5 -193.832 = -110.33 = 114 204.467 = -90.47 System loss = Qcond Qw = 112 109.09 = 2.91 = 240 376.20 = -136.20 = 323 428.87 = -105.87 System loss = Qe, R12 Qe,Elec = 126 40 = 86.00 = 262.5 119 = 143.50 = 342 242 = 100.00 UMAR DARAZ Page 15 of 22 Thermodynamics Lab 2 Discussion of Results The observation table of results has been listed on page 8 9, and it is followed by all the calculations required to complete the table or to get the results. The experiment has been repeated three times, so all the results (values have been listed three times. In the calculation section the system losses and heat energy are shown as negative val- ues, its because the work is done on the system and heat is being removed from that particu- lar system, in this case its condenser. The positive values of system loss and heat energy shows that heat is being add in the system and work is done by the system, and in this case its evaporator. The condenser pressure i.e.900 KPa, was not exactly 900 KPa. As we were set- ting the pressure manually, so in the whole experiment the pressure was 900 KPa  ± 10%, it was because of the fluctuation in the gauge needle, so we assumed the considered pressure. The compressor pressure applied by spring balance force, affected the work done of the com- pressor on the refrigerant R12, because to get an accurate compressor work done, the two tips of the spring balance should be in balance (level), but during an experiment we were getting random values (results), so then I realised that something is wrong, so I looked at all the components of the refrigeration plant, and I found that the two tips of the spring were not bal- ance. Hence to get right results we had to redo the experiment. The throttling device or valve has a huge impact on condenser pressure, because by opening or closing i.e. changing a flow rate make a considerable amount of difference on condenser pressure and evaporator tem- perature. Motor loss refers to the consumption of electrical energy not converted to useful mechanical energy output, but in this case energy loss means less input energy to the compressor, which means a refrigerant would be less compressed by a compressor, so less heat would be re- moved by the condenser, and even after passing through the valve the refrigerant would still have a high temperature and pressure, hence less refrigeration would occur in a vapour com- pression cycle. Therefore we need to take into account power losses in the electric motor. In order to study this process more closely, refrigeration engineers use this pressure en- thalpy diagram shown in Figure 5. This diagram is a way of describing the liquid and gas phase of a substance. Enthalpy can be thought of as the quantity of heat in a given quantity, or mass of substance. The curved line is called the saturation curve and it defines the boundary of pure liquid and pure gas, or vapour. In the region marked vapour, its pure va- pour. In the region its marked liquid, it is a pure liquid. If the pressure rises so that we are considering a region above the top of the curve, there is no distinction between liquid and va- pour. Above this pressure the gas cannot be liquefied. This is called the Critical Pressure. In the region underneath the curve, there is a mixture of liquid and vapour.

So we go straight from that temperature of left side of the doom (saturated liquid) to the right side of the doom (saturated vapour line), and then following the temperature gradient line, we go down and record the enthalpy value at that temperature and pressure. Similarly for the stage 2, we find h2 on x-axis. When the refrigerant leaves the condenser, it obtains a saturated liquid phase (left side of the doom), so taking the reference of condenser pressure line (red line), we take a straight line parallel to the y-axis, and wherever it meets the x-axis gives a value of enthalpy (h3) at stage three. In actual refrigerant plant, enthalpy at stage 3 and stage 4 is not same, but for the sake of calculation we assume that its an ideal condition and enthalpy at these two points is same. Test 1 As Compressor suction = t1 = -23.5 0C and condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h1 = 340 KJ/Kg Compressor delivery = t2 = 59.9 0C and Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h2 = 385 KJ/Kg Here Liquid leaving condenser = t3 = 31.6 0C And Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h3 = 225 KJ/Kg As mentioned earlier that h3 = h4 (Ideal condition) Hence the enthalpy h4 = 225 KJ/Kg But using temperature at evaporator inlet, t4 = -32 0C, we get Actual enthalpy value, h4 = 160 KJ/Kg Test 2 As Compressor suction = t1 = -22.6 0C and condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h1 = 345 KJ/Kg (from above p-h diagram) Compressor delivery = t2 = 68.5 0C and Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence using Figure 4, we get enthalpy h2 = 400 KJ/Kg Here Liquid leaving condenser = t3 = 34.8 0C And Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h3 = 240 KJ/Kg UMAR DARAZ Page 18 of 22 Thermodynamics Lab 2 As mentioned earlier that h3 = h4 (Ideal condition) Hence the enthalpy h4 = 240 KJ/Kg But using temperature at evaporator inlet, t4 = -23.6 0C, we get Actual enthalpy value using figure 4, h4 = 170 KJ/Kg Test 3 As Compressor suction = t1 = -5.2 0C and condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h1 = 360 KJ/Kg Compressor delivery = t2 = 69.4 0C and Condenser Pressure (Abs) = Pc = 1001.663 KNm-2 Hence the enthalpy h2 = 420 KJ/Kg Here Liquid leaving condenser = t3 = 33.8 0C And Condenser Pressure (Abs) = Pc = 1001.663 KNm-2, Evaporator Pressure = 40 KPa Hence the enthalpy h3 = 250 KJ/Kg As mentioned earlier that h3 = h4 (Ideal condition) Hence the enthalpy h4 = 250 KJ/Kg But using temperature at evaporator inlet, t4 = -19.1 0C, we get Actual enthalpy value at this stage, h4 = 180 KJ/Kg 6However the expansion of the high pressure liquid, process 5 1 above is non reversible. Notice that Expansion is a constant enthalpy process. It is drawn as a vertical line on the P-h diagram. No heat is absorbed or rejected during this expansion, the liquid just passes through a valve, like water coming out of a tap. The difference is that because the liquid is saturated at the start of expansion by the end of the process it is partly vapour. Point 1 is inside the curve and not on the curve as described in the Evaporation process. At point 4 it starts to condense and this continues until point 5 when all the vapour has turned into liquid. Point 5 is saturated liquid. If more heat is removed, the liquid cools. It is then called sub-cooled liquid. Hence h4 is on a saturated liquid line (left side of the doom), and does not appear in a vapour compression cycle, and this is the case in all three tests. 6 http://www.alephzero.co.uk/ref/vapcom.htm#ph UMAR DARAZ Page 19 of 22 Thermodynamics Lab 2 As there is no moving part in the whole refrigeration plant apart from motor shaft of a compressor, so work done by them is zero, i.e. w = 0 So using steady state energy equation, we get W Q = h2 h1 Equation (2) As W =0, so equation (1) becomes Q = h2 h1 Or Q = h1 h2 Equation (3) The coefficient of performance or COP (sometimes CP), of a heat pump (i.e. refrigerator) is the ratio of the change in heat at the output (the heat reservoir of interest) to the supplied work.To find Cop value of refrigeration plant as well as for the refrigerant is a good practice, because this will illustrate that how much efficient of these two are. 7It takes a lot of heat to evaporate liquid. In other words a small amount of liquid circulating in a refrigerator can perform a large amount of cooling. This is one reason why the vapour compression cycle is widely used. The refrigeration system can be small and compact. Also from a practical point of view heat exchange is much better when using change of state evaporation and condensation. However the expansion of the high pressure liquid, process 5 1 above is non reversible. And so the efficiency of this cycle can never even approach Carnot efficiency. 7 http://www.alephzero.co.uk/ref/practcop.htm UMAR DARAZ Page 20 of 22 Thermodynamics Lab 2 Conclusion 8The vapour-compression cycle is used in most household refrigerators as well as in many large commercial and industrial refrigeration systems but the efficiency of this cycle can never even approach Carnot efficiency, because of its low coefficient of performance. In the refrigeration plant the operating parameters can be varied by adjustment of condenser cooling water flow and electrically heated evaporator supply voltage. Components have a low thermal mass resulting in immediate response to control variations and rapid stabilisation. Instrumentation includes all relevant temperatures, condenser pressure, evaporator pressure, refrigerant and cooling water flow rates, evaporator and motor power, motor torque and com- pressor speed. The most of components of refrigeration plant used in this experiment (R712) are manually calibrated scales (not digital), and based on this poor calibration all the recorded results are being guessed on the base of individual judgment, which is wrong most of the time. Anyway a small amount of liquid circulating in a refrigerator can perform a large amount of cooling. This is one reason why the vapour compression cycle is widely used. The enthalpy values which are being recorded directly from enthalpy pressure diagram (Figure 4), and based on how unclear that diagram is, I would say it is not a great source of information, but still we use this to find enthalpy. The system (refrigeration plant) has some losses, which have described earlier in this report, this includes motor loss, condenser and evaporator loss. In conclusion, I would like to say that by doing this experiment I learnt a great amount of knowledge, about refrigeration plant, and how it works, what kind of cycle more often use for this, how much efficient is this and how to calculate the different losses in this system. I would say by understanding the operation of this small scale refrigeration plant, I think I would be able to operate on an industrial scale refrigeration plant, because the basic principle is same. 8 http://www.alephzero.co.uk/ref/vapcomcyc.htm UMAR DARAZ Page 21 of 22 Thermodynamics Lab 2

What a Multinational Company?

What a Multinational Company? 1- Introduction: For better understanding this is important to discuss what a multinational company is in first place. In short words multinational company can be defined as a company or an organization that serves or produce in more than one country is known as multinational company. Other names use for such kind of organizations is Multinational Corporation (MNC), Transnational Corporation (TNC) or Multinational Enterprise (MNE). Multinational organization can be engaged in manufacturing, services or the exploitation of natural resources in the operating countries. Different writers described different definition of multinational companies. According to Moore Lewis (1999, P. 21) stated that â€Å"an enterprise that engages in foreign direct investment (FDI) and own or controls value adding activities in more than one country is known as multinational enterprise†. As Jones (1996, p.4) says â€Å"An MNE is usually defined as firm that controls operations or income generating assets in more than one country.† There is a long list of multinational firms like Sony, Nestle, Wal-Mart Stores, General Motors, Ford Motor, ConocoPhillips Microsoft, Nokia, Toyota Motors, Intel, Coco-Cola, Sony, IBM, Nike and Citigroup etc. Now the main question is about the multinational companies of different origin adopt different approaches of HRM practices. To discuss this section this is really important to discuss the HRM practices in first place, to define what HRM is and then its practices will be discussed throughout this essay step by step, and then practices of HRM in broader context for the MNCs or MNEs. HRM is modern word use in the businesses, which can be defined as â€Å"a model of personnel management that focuses on the individual rather than taking collective approach†. (www.dictionary.bnet.com). As Pennington Edwards (2000, P. 4) stated that â€Å"Human Resource Management (HRM) is a new way of thinking about how people should be managed as employees in the workplace†. It can be classified into two schools of thoughts.i.e. Hard HRM Soft HRM. Both types of HRM are under studies of different authors in detail. Now to concentrate on the question directly a survey is going to be under studies â€Å"Country of origin effects and HRM in multinational companies† which took place in 2007 by P. Edwards et al. In which he discussed 302 UK based multinational companies, which cover both UK owned and overseas owned companies. This study will play an important part in the essay to get the conclusion either multinational companies of different nationalities have different HRM approaches and practices or not. 2- Challenges In Multinationals According to Brett, Jeanne Kristin, 2006, international businesss nature is going under a sea change. The globalisation, multi-nationalisation, and the geographical diversification is pushing companies towards change in their management structure and style. Multinationals now need to consider regional market conditions and develop strategies to cater to each of the regional markets. Culture Shock Culture shock is the big challenge for multinationals, the difference brings the different thinking ways and working ways, and it needs time to adjust it. In most cases the expatriate manager prefer to emphasize and require the home office or home country values on the host countrys employees instead of accepting and learning within the new culture. (Adler, 2002) Lack Of Cross Cultural Training In fact, most multinationals ignore this training program during the staffing management. However, the better understanding about culture block can help managers to improve the effectiveness of staffing management. For example, The managers at Bell Canada were totally asked be training about Muslim laws of drinking and the treating of women there before he or she assigned a project for Saudi Arabia such like constructing the telephone system in there. (Adler, 2002) Family Problems Family problem for PNC manager is another challenge. The overseas employees always think of their family. Sometime, such emotion will effect the concentrations in their work. These difficulties are usually underestimated. What the organization should do is to assist expatriates family to adapt their new environment. (Dolan, 1996) 3- HRM Functions In MNCs Team members of multinational companies come from different countries with the different culture, economic, religions and habits. All of these differences bring the different thinking and working methods, thus, how to manage the multicultural team is a big challenge for the HRM in the multinationals. In the article â€Å"Managing multicultural team†, the author states that â€Å"Communication in Western cultures is typically direct and explicit. In many other cultures, meaning is embedded in the way the message is presented. The differences can cause serious damage to team relationships† (Jeanne Breeet , Kristin Behfar, and Mary C. Kern, 2007) . Retaining Subsidiary Staffs Retention It can be argued that the retention of staffing in the multinationals subsidiary conducts huge influence. The transfers between the PCNs, HCNs and the TCNs are the big issues in the staffing management strategy. Scolders identify that the HCNs and TCNs who are sent to the corporate headquarters (HQ) called inpatriates. As this article mentioned before, the ethnocentric approach, the polycentric approach, the regioncentric approach, and the geocentric approach are the four major nationality staffing policies in the international staffing, by analyzing the complex and the new situation appear in the relationships between the HQ and subsidiary, B. Sebastian Reiche (2007) explores the international stiffing-related retention strategies . Firstly, he claims that a pluralistic and consensus-driven approach to international staffing enhances the retention capacity of international staffing practices through increased responsiveness to and involvement of the respective local unit. He states that the knowledge and skill from the local staff can help multinationals to reduce the risk and culture-bound in the local market. He also believes that this approach can improve the loyalty of local staffs, and the local staff can achieve individual career plan to cohere the institutional development plan. At the same time, he states that the PCNs still act as the vital role for informal controlling and coordination in the multinational companies. Secondly, he indicates that expatriation of local staff can help to retain the MNCss retention. In this approach, he states that the â€Å"inpatriates can share their social and contextual knowledge of the subsidiary environment with managers at the HQ. And also inpatriates tend to be accepted by HCNs more willingly than foreign personnel.† HRM is all concern about the employees at the work place, but the demands from HRM gone up as the education rate grown up. As Pennington and Edwards (2004, P.4) stated that â€Å"As a level of education become higher, a greater proportion of the population world wide expect more than fair treatment, they seek a range of intrinsic rewards such as job satisfaction, a degree of challenge, a sense of career progression and satisfying relation with co workers†. Selection Recruiting:- The main function of HRM is selecting and recruiting, no matter the firm is domestic or multinational. Staffing issue for domestic managers and MNCs managers are not very different for recruiting for the middle management or ground floor workers, but for selecting and recruiting of top management then the choices come like parent country national (PCNs), Host country national (HCNs) or third country national (TCNs). According to Parlmutter (1989) divided into three main categories. ‘Ethnocentric where top management favours PCNs managers, who are posted abroad for a period of time. ‘Polycentric where top management give choice to subsidies to fulfil management posts themselves, and ‘Geocentric when top management recruits managers globally and post them anywhere in the world. For example Japanese style of HRM dont rely on interviews and job advertisements, they select the people from the universities and the most top MNCs can afford the students from the most prestigious university. According to Keeley (2001, P.62) stated that â€Å"unlike the most Western companies detailed job description rarely exist. The company seeks to determine if the prospective employee has the type of personality that fits in well with the atmosphere at the company.†While US MNCs rely on â€Å"interview must† attribute of HRM practices in their subsidies. In China, they had no selection processes per se when they first started. Senior managers were appointed by community government-officials. Most of the new hires were based on employee referrals. Selection criteria were based on nepotism and contacts. Hiring decisions are influenced by the following in china: A persons ability to perform the technical requirements of the job A personal interview A persons ability to get along well with others already working here Having the right connections (e.g. school, family, friends, region, government, etc.) The companys belief that the person will stay with the company An employment test in which the Person needs to demonstrate their Skills Proven work experience in a similar job A persons potential to do a good job, even if the person is not that good when they first start How well the person will fit in the companys values and ways of doing things Future co-workers opinions about whether the person should be hired (Huczynski, Andrzej / Buchanan, David, 2001) A most important attribute in Japanese style of HRM is called â€Å"Shushinkoyo† which means life or long term employment. This is considered the success key of Japanese HRM as stated by Keeley (2001, P.65) â€Å"Nevertheless, a number of scholars both Japanese and non Japanese have praised ‘Shushinkoyo and have attributed the success of Japanese enterprises to its practice.† Here this shows that multinational companies from Japan apply different approach for selection the new recruits while US MNCs rely on a different phenomena of selection and recruitment. Performance Appraisal:- This is the HR attribute which has significant attention from both academics and practitioners, the appraisal system in US MNCs use to reduce the labour force as stated in Edwards (2007, P. 40) that â€Å"some US companies, GE for instance, have become known for using the appraisal system to remove the lower- performing employees from the workforce on a regular basis and /or to identify those in need of ‘remedial action for their performance level.† But in Japanese MNCs the companies gives the life time or long term employment as mentioned by Keeley (2001) that it is one of the best attribute of Japanese HRM in small Japanese enterprises or Japanese MNCs. Differences can b seen in the Edwards (2007) survey of Japanese and US multinational companies based in UK, where he stated that â€Å"US companies are more likely to emphasise the importance of behaviour in relation to corporate values, while Japanese firms give lower importance rating to quantitative or qualitative i ndividual evolution criteria, and criteria based on corporate values.† In large organizations the performance review on periodic basis, this is second task of organizations HR departments, after hiring an employee and on the basis of performance employee get bonuses, promotions and rewards. Performance appraisals give opportunity to the workers (individual/group) to get prepare for the future goals of firm. Pay, Compensations, Rewards Benefits:- Compensations like hourly wages and annual salaries while benefits are like life insurance, pensions and sick pays etc. According to Cherrington (1995) stated that compensation should be legal and ethical, adequate, motivate and fair, and should be able to give employment security to the worker. Pay compensation and rewards are not really different from each other, but in simple words rewards is the term use to motivate and to get the future goals by means of workforce for an organization, the reward system plays an important role, by reward (individual/group) the workers get appreciation and get themselves more committed to the firm. These are the some of the main features and functions of any (domestic/MNCs) firm HR department. In Japanese style of HRM they use a Japanese term ‘Nenko Joretsu which means seniority system, where in Japanese HR management the wages goes up with the age and experience, as stated in Keeley (2001, P. 76) said that â€Å"though nenko is most often translated as ‘seniority†. While US and Europe MNCs apply the performance related pay system. This is the most important phenomena of MNCs HR system when they go to borderless business. According to Edwards (2007, P. 46) stated in his survey that â€Å"Nationality has some effects. For example, American firms are likely to give organisational performance a higher importance rating for the KEY GROUP than others firms. UK firms are more likely emphasis individual output measures for LARGEST OCCUPATIONAL GROUP.† It shows the difference in attribute of HR practices and approaches in multinational firms. Training Development:- This is one of the important as well as crucial task for HR department for a firm operating globally, in this area of HRM multinational companies of different origin follow different approaches, for example according to Tung (1981) stated that â€Å"by comparing US, European and Japanese corporations, Americans firms it seems tend to underestimate the importance of training, whereas most European and Japanese organizations see this as a highly important area of attention†. The objectives and goals of training and development are to make sure the skilled and willing workers are available in the organization. Training and development are important to create a smarter working environment. In China, medium and large companies have formal training programmer and many have established special facilities for teaming purposes. Because of the lower educational level in the rural areas, the quality of the rural labour force is significantly in urban areas. Experienced, well-qualified staffs are in short supply. To disadvantage of hiring Key personnel from a shallow pool of talent, they invest heavily in training. Training is an important investment in human capital. Training improves an individuals performance and increase organizational effectiveness. (Ahlstrom Garry, 2001) Japanese MNCs pay less attention to training and development attribute of HRM, the reason might be the less mobility of workers in the Japanese firms, as they use the term ‘Shushinkoyo. According to Keeley (2001, P. 88) stated that â€Å"A study of the Japan Productivity Centre found differences in the attitudes towards training in Japanese and American firms.† Where Keeley stated that from the study and respond of both countries towards training issue were positive but American firms were strong and more positive then the Japanese firms and he also stated that Japanese firms arrange training on ‘request basis. A strategy which makes a firm successful is not easy to implement when they go beyond the borders, because of the barriers which might be language, religion, culture and legislations etc. As Keeley (2007, P.89) stated that â€Å"HR practices which makes a firm successful in domestic environment are difficult to implement in their overseas subsidiaries.† 4- HRM Approach In Multinational Firms: Now in this essay some of the multinational firms characteristics will be studied to see do they get affected by the country where they belong to in their HR practices and approaches or not? There are many MNCs, the country which has most MNCs is USA, and after that are Europe, Japan and Germany. There are many writers who discussed the issue of ownership and HRM in MNCs like Evan, Lank and Farquhar (1977), Barlett Goshal (1989), Rozenzweig Nohria (1994) and Innes Morris (1995) etc, which prove that the issue of ownership has been in discussion from ages, as according to Economist (1995) said that â€Å"the issue of ownership is central to the number of important policy related and academic debate in the area of HRM and IR, One line of argument is that, with increasing globalization MNCs are becoming stateless players, detached from individual nation states†. MNCs of different origin work in the host country by applying its local mechanism of HR practices and approaches, because it is not possible to work and apply 100% approaches of the parent country, as according to Rozenzweig Nohria (1994) said that â€Å"a rank and file IR issues are more likely to exhibit ‘local isomorphism †. There are many arguments about the affection of country of origin on MNCs HR practices, the reasons are many for MNCs to adopt different approaches of HRM, as Ferner (1997) described that â€Å"in short, it is imperative to take into account the dynamic of nationality as a factor affecting the behaviour of MNCs. The modernization of political institutions, the rapid pace of technology, the internationalization of product itself and changing pattern of international market and competition, all are likely to modify to pre existing national structure although not necessarily in the direction of convergence of different national systems on a si ngle model†. Now the essay will point out some differences in Chinese and American Human Resource Managements. China is one of the fastest growing economy of the world, according to Zhu (2005, P.2) explained that â€Å"the past two and half decades of reforms and impressive economic growth have witnessed an unprecedented enthusiasm for the establishment of foreign invested enterprises (FIEs). Many foreign companies have expended their operations into china, attracted mainly by the sheer size of its potential market†. There are many multinational firms in China like Aluminium Corp (ACH), China Petroleum Chemical Corp (SNP) and China Unicom (CHU) etc. The main practice of HRM is selection and recruitment as mentioned above, and the difference between the process of selection of Chinese and USA approach is, in USA model of HRM job interview is essential for filling a major position, while in Chinese HRM mostly jobs are allocated by government and interview process is not common. In reward system the USA model of HRM offers a variety of incentives system, while Chinese HRM system is different from USA, in Chinese system salary ranges are narrow, group reward system is common, but the pay system is more motivate than American pay system. In performance appraisal USA model of HRM believes in two way communication, while in Chinese model supervisor have absolute power and authority to evaluate subordinates, in USA participative management is welcome and encourage, but in Chinese HRM collective leadership is common, and in major decision making, the involvement of workers is symbolic. The difference can be seen in different origin or nationality MNCs that the US MNCs are significantly more like to collect information on employee attitude bring together HR managers from different countries and use HR international shared services, Japanese organizations are less likely to collect data centrally, while French origin MNCs acting more likely in US style of HRM practices, and German origin MNCs firms follow Japanese style of HRM practices. (Jackson, 2002) The best example is British American Tobacco (BAT), which is operating in a number of countries in the world, i.e. Pakistan, South Africa, UK, Japan, Saudi Arabia and many more. As this is an American based firm, and American have an ‘interview must attribute in their HR practices, they apply the same approach for selecting and recruiting in the host country Pakistan, and the adopt some practices of Pakistan HRM practices (host country) like monthly payment of salaries instead of weekly wages, so its means BAT reflected their parent country HRM practices in some ways and in subsidies like UK, BAT apply the same HR practices and approaches as the parent country have, because the culture difference is not very distinct from each other i.e. UK and USA. (www.bat.com) (self experience as a worker of BAT in Pak) 5- Conclusion This essay was carried out to see, do multinational organizations of different origin have different approaches to international human resource management? There were some evidences that showed the answer as ‘Yes they get affected by its country of origin in on or other way, but it is also proved that the most of MNCs adopt ‘the best fit policy when MNCs start operating in a host country, because of the obstacles in the host country, i.e. language, religion, norms and values, culture and legislations. Writers in HRM field have different opinion about the behaving of MNCs, so the best option for MNCs is to apply the ‘best fit approaches of the HRM practices, means combination of both (Parent Host countries) HRM practices. The issue of ownership country of MNC has been in discussion for ages, but still there is not a 100% accurate answer came out as according to Ferner (1997) said that â€Å"but existing research has failed to systematically explore differences†. All these discussion and researchers efforts bring the conclusion that in some HR attributes in MNCs they follow the a universal approach while in some they follow the different approaches in HR practices, according to the survey by Edwards (2007) stated that â€Å"throughout the report, we have noted the persistent influence of nationality. There are clear national differences in all four area of HR/ER: Pay performance, Learning development, employee involvement and employee representation.† But the bottom line can be that: yes! Multinational firms of different origin can be effected by the parent country HR practices when the run business in other part of the world instead of the home country. There are some obstacles for multinational companies which can stop them to apply the 100% parent country HR practices in their subsidies like legislation of the host country, rules and regulation and more, there is term used in Edwards (2007, P.29) survey of Multinational companies in UK called discretion or local autonomy. Which shows multinational companies of different origin give the power of decision making and freedom to their subsidies? In that survey the high discretion power firms are Japanese, which means Japanese multinational companies give more freedom to their subsidies comparatively to American, French and other Multinational firms of different origin. But another thing can be the law enforcement of subsidies (host Country), the example can be Germany where the rules and regulation are strict so the difference in practices of HR of a multinational firm would not be as bigger as in Pakistan, because of the law enforcement, like differences would be less in Europe but it would be greater in Asia.
