The Organization System Essay Example for Free
The Organization System Essay The Organization System consists of the people who worked for achieving their goals as a team. In an organization, there is a hierarchy consisting of a leader at  the top to the people at the bottom working under him. This hierarchy is subdivided in lower hierarchical order also. Thus in the organization different set of people comprise themselves to form an organization. The leader  keeps his sharp look at the team to watch whether the organization is functioning effectively or not. The role of the leader is very important in organization to keep it running.            The responsibility of a leader is to correlate the members of the organization effectively. Thus he also plays the role to eliminate the situations of conflicts. Thus in these various functions of the leader, the leadership quality for removing the conflicts in the organization is also extremely important for him. By removing the conflicts the leader will be in leading stage to work along with the members of the team.            The challenge for leaders is to effectively manage and resolve such conflicts or, better yet, anticipate and prevent them from happening at all, says CCLs Patricia Ohlott (Patty Ohlott         page 1). According to the traditional view of conflicts, the leader must have to avoid the conflicts which may be for higher designation, appraisal and others. The leader by using his leadership qualities has to eliminate this uncharacteristic and irregular part. In the traditional view related to the theory, the leader has to decline the conflict and get the member to continue the  work.            According to the human relational point of view for conflict, the conflicts will happen in the organization. The leader can resolve the problem by creating routine contact with his team. This is the simplest way of resolving the conflicts. by having the reward system one can resolve the conflict. But according to the interactionist view, the conflicts every time generate a new situation. Thus the leader must be innovative in his ideas, so that he can handle the various new situations of conflicts. The leader every time will be able to introspect his organization by having conflicts so that he can judge the situation whether his organization is working effectively or not.            The leadership quality enables the leader to improve the capability or capacity of the organization. When the leader will be working effectively, then the functioning of the organization will continue successfully. The volatility of the organization depends on leader itself. If the leader is able to predict the upcoming situation, then the organization will not endure itself. The leader has to predict the situation whether they are related to the market or related to the internal affairs with in the organization. The leader has to eradicate the complexity by using the different techniques and reviewing inside organization and the market situation.            The power means authority to govern or leading the organization. â€Å"Policies or lack of policies often are  the initial reason for conflict†. â€Å"Personality clashes, clumsy communication and lousy dispute resolution techniques are often why conflicts escalate† (PSO Power Tools       page 1).            In case of traditional view of conflict, the power can resolve the conflict necessarily. By having the power the person in charge can dismiss, suspend demote a particular who is creating the conflicts. By the power, the leader can negotiate with the stakeholders and work for the paramount functioning. The power according to the human relations view, can resolve the conflicts as by having the power, the continuously happening conflicts. The power can suppress the conflicts by eliminating the evil stuff which is originating the conflicts. By power the person in charge can influence his downstream to work by having team-work and coordination. According to the ineractionist view, the conflicts  are cause to decentralize the power. Thus the person having power in an organization has to correct the situation to stabilize the issue. Thus the person can be able to review his state and outcome of the conflicts to build the new strategies for resolving the further difficulties.            The power can enhance the capacity of the organization by keeping watch on every perspective inside organization and suppress the troubling elements. The powerful person in an organization can acquire the position to create the opportunities for the benefit of the organization. The volatility in an organization can be eliminated by using the power. The power has to predict the situation by negotiating effectively with the other beneficial sources and the internal sources within the organization. The complexity is feature which can be reduced by the power either forcefully or by indulging the complex parts or sources in other streams for the fruitfulness of the organization.            The concept of organizational politics defined as the as the exercise or the use of power, with power being defined as a  potential force. More than 90% of respondents said that politics is common in organization. 89% said that successful executives must be good politicians and 76% said that higher one progresses in an organization.            The politics is the key factor for creating the conflicts in an organization. The politics according to the traditional view, the politics is one of the key factors for containing conflicts inside an organization. The political scenario in an organization will create misbehavior in the functioning of an organization. The occurrence of the conflicts is basically many times based on the politics only. According to human relation view, the conflict  can happen in any organization. The structural changes happens, are due to the politics by the members inside an organization. The member causes the politics for stopping other’s growth or for their personal growth also. The interactionist view laid some different idea over the politics in an organization. The politics causes the different circumstances many a times. So the politics causes the fact for an organization to review its strategies  inside an organization.            The politics can degrade as well as enhance the capability of an organization. The politics can cause problem to opponents for better working of the organization. The volatility is the factor which is due to the politics in an organization. For example, if one policy is being implementing in an organization, the politics by someone can revert the position also. Similarly the complexity in the hierarchical structure is also caused by the politics. Due to it, the eligible person get ignored many of the times, which causes the complexity and hence instability.            Thus in an organization the leadership, power and the politics are very important and play a key role in better functioning of it.

Old And New Testament Views On Social Justice Religion Essay
Old And New Testament Views On Social Justice Religion Essay Christians regard the Bible as a uniquely important source for human life on matters of belief and practice. For human beings to live a life that is meaningful and dignified, they have to be in a just and fair society that looks up to the need of others. For this to happen justice has to be emphasized, it has to be the driving force. In the Bible, God clearly imposed social concern upon his people especially the poor and the marginalized. In Bible, numerous passages such as; in 1 John 3: 17 and James 3:14-17 draw peoples attention towards social concern and social justice. DEFINITION OF SOCIAL JUSTICE. Defining social justice, Dr Paul Kengor said, Historically, social justice has meant different things to different people, and so equally todayà ¢Ã¢â€š ¬Ã‚ ¦(Online). This statement actually means that social justice is a just a branch of justice that accommodates all forms of justice, it being restorative justice, economic justice distributive justice, rectificatory justice and so forth. We can in this paper therefore, say that biblical justice entirely consists of social justice because there are many chapters like Matthew 18:23-35 it talks about penal fairness that needs punishment by the book but lacks mercy is not the kind of justice desired by God. Also in Matt 20:1-16: the summary on social justice is an economy of care for the common good through social sustainability, healing, and transformation. Marshall in his book said, There is huge amount data to deal with. There are hundreds of texts in the Old and New Testament, which speaks explicitly about justice, and hundreds more, which refer to it implicitly. Justice is in fact one of the most frequently recurring to topics in the Bible (2005:3). What actually Marshall means here is that, Biblical justice covers all aspects of life in terms of justice such as the personal and the social, the public and the private, the political and religious, the human and nonhuman. But on the other hand, such remarks may mean that biblical justice does not consist entirely of social justice, but also independent justices such as political justice and many others. Marshall said, Justice entails the appropriate distribution of social benefits and penalties and contending parties(2005:6). Still more despite such analysis, social justice in biblical justice concept, remain inclusive of other justices because, the product of each justice is a social concern to the need. OLD TESTAMENT CONCEPTS OF JUSTICE Marshall in his book wrote, Often in Hebrew Bible, righteousness (sedeqah) and Justice (mishpat) occur as a word pair with virtually identical meaning: But let justice roll down like water, and righteousness like an overflowing stream (Amos 5:24)(2005:12. So this statement means that righteousness in the Bible incorporates the idea of doing justice and doing justice conveys the idea of putting right what has gone wrong. Social justice of the Old Testament indeed was concerned with giving according to need thought it worked antagonistically; to the other it was really social justice and to another a different justice. For example, the deliverance of Israel by God from slavery in Egypt, it was a justice on social concern to them by God; but it was under a covenant. Marshall said, Biblical justice is therefore covenant justice. It is the practical outworking of Israels special relationship with God (2005:15). We can say, that indeed God did well for the Israelites out of the obedience to the law He gave them through Moses at Mount Sinai. The Law actually reviews what needed for Israel to live in peace, to experience what the God intended for human society, and all was done out of the covenant which was made. In this justice, Israel had seen God intervene in their liberation from the oppression of slavery, to lead her safely through the wilderness and to constitute her as a free independent people. This became Israels own experience that God was a God of justice, Isaiah 30:8. Gods justice towards the covenant people was a call the Israelites to act towards one another I the way God had acted towards them, with justice, mercy and equity. It is also recorded in some chapters like in Leviticus 19: 15 You shall not render an unjust judgement; you shall not be partial to the poor or defer to the great: with justiceyou shall judge your neighbour. It is aslo written on social justice in the Old Testament that, You shall not deprive a resident alien or an orphan of justice; you shall not take the widows garment in pledge. Remenber that you were a slave in Egypt and the Lord your God redeemed you from there; therefore I command you to do this, Deuteronomy 24:17-18. This has actually pointed to Marshalls description of Gods justice for covenant, through biblical justice which leds to social justice and further with the concerns with giving according to need. Sometime, Biblical justice points at social justice with no concern to giving according to need. Marshall said, justice requires impartiality; at other time partiality(2005:38). In Exodus 23:3, nor shall you be partial to the poor in a lawsuit. As for Marshall, he poits to this kind of justice in accord to what he called criminal justice. Actually, we can support his point with the biblical justice on social justice in Exodus 22:21-24. God warns the Egyptians with His wrath in favour of the resident aliens, widows and orphans. In other instances, Marshall said, Gods bias or preferential option for the por is, ultimately, in the interest of equity. In the perennial struggle for social Justice (2005:41). This statement from Marshall actually talks about distributive justice that considers fair dealing between men. This is also a biblical justice of Gods bias according to Marshall, can be seen through Gods historic intervention to rescue powerless impoverished Israel fro the hands of the Pharoahs in Egypt, and feed them in wilderness. This is Gods justice which is purely social justice which was give according to the neen of Israel at that particular time. The other Gods justice which is in nature of social justice that is concerned with the giving according need is actually in Deuteronomy 24:19-2. This justice provides specific welfare and protection for the por and vulnerable. It is inform of law which guarantees access to food. They are given justice according to the need for survival. This is purely a social justice for social concern in biblical justice. OLD TESTAMENT CONCEPT OF JUSTICE. In the New Testament, biblical justice is not different from that of the Old Testament because the words that are used for justice remain the same, like righteousness but differs only that most of them are teaching by Jesus Christ. Jesus in part of this bible portrays biblical justice consisting social justice by barely giving according to the need. Marshall wrote, At the outset of His ministry, Jesus deliberately evoked this messianic expectation by defining His own mission in terms of bringing justice to the poor (2005:50). Indeed this is what Jesus had started to do, Isaiah 61:1. The spirit of the Lord is upon me, because the Lord has anointed me to bring good news to the oppressed, to bind up the broken -hearted, and to proclaim liberty to the captives release to the prisoners. For Jesus to accomplish this he rejected social discrimination, he promoted social justice and gave it according to the need. To the rich man who wanted to know he was to do to enter the kingdom of god, Jesus to him to sell all that he had and share the money with the poor. This is another biblical justice from our Lord Jesus Christ, as sign for social justice, which he had promoted. To fight social discrimination, Jesus openly criticized the self-righteous arrogance of the religious experts and knowingly antagonized them by enjoying intimate fellowship with sinners and outcasts. For example in Matthew 9:13 when He said, I desire mercy, not sacrifice. For I have come to call not the righteous but sinners and also in Luke 5:27-23, a story of how He met Levi the tax collector and how the Pharisees and Scribes complained about it. Therefore, social justice of Jesus who is characterized by giving according to need viewed in Levis story, Jesus also assessed a new community, which was inclusive, and the poor were to be given preferential option. CONCLUSION. Indeed, both Old and New Testament provide Biblical justice which is entirely consist of social justice that is concerned only with the giving according to the need because it is a complex multifaceted reality. It relates to every dimension of human experience. Biblical justice to its social justice seeks to restore dignity to those who have been unjustly deprived of, to meet their basic needs. Jesus proclaimed of the Kingdom of God as a social justice. That is, proper use of wealthy and not excluding the weak and the vulnerable from participation in national matters.

Supplier Selection Process in the Aerospace Sector
Supplier Selection Process in the Aerospace Sector Executive Summary The ever increasing competition in global markets today has led businesses and companies to find different methods for reducing production and manufacturing costs in order to maintain their competitive edge. The competition has no longer remained company to company but has become supply chain to supply chain. From a buyers perspective a qualified supplier is a key factor to reduce costs. Thus supplier selection and evaluation has gained vital importance in the supply chain management environment. It is extremely essential to develop a supplier selection model which is efficient, effective and considers all the aspects required by the company. A number of supplier selection methods are available in the current literature. Creating a model based on these methods that addresses the particular requirements of the company is vital. The following paper is in 5 sections. The literature review in the first section is on the various methods for supplier selection and evaluation. The following methods are reviewed. Mathematical Programming Data Envelopment Analysis Analytical Hierarchy Process Analytical Neural Network Fuzzy Set theory Along with the review of the methods a discussion on the evolution of supplier selection criteria is also included in the first section. In the second section, two existing supplier selection models in the aerospace sector have been critically reviewed. The description of the Aerospace industry and comparison between the two models is included in the third section. To determine the essential criteria to be included in the model and prioritizing them, the research methodology used was a survey design. The results of the survey are included in the fourth section. The fifth section contains recommendations for building a new model for supplier selection in the aerospace sector. Introduction One of the major topics discussed in most of the production and operations management literature is supplier selection and performance evaluation of suppliers. It is one of the most critical activities of firms due to the increasing significance of the purchasing function (De Boer et al., 2001). The main objective of a supplier selection process is to maximize overall value to the purchaser, reduce the purchase risk and develop a close and long term relationship between the buyer and supplier. Supplier selection is a multi-criterion decision making problem and a number of conflicting factors affect its outcome. The factors taken into consideration are wide ranged and are both quantitative as well as qualitative (Ho et al., 2009). Operational research offers a range of methods and techniques in the form of models which can support the supplier selection decision making. A number of supplier selection methods have been proposed such as data envelopment analysis (DEA), analytic hierarch y process (AHP), mathematical programming, fuzzy set theory and vague set theory, multi attribute rating systems etc. A literature review of international journal articles discussing different multi-criteria supplier selection methods is carried out in this paper. The methods that are prevalently applied in practice, the priority of the evaluating criteria and evolution of selection criteria are also discussed and reviewed. The aim of this paper is to carry out a literature review of the various methods and criteria for supplier selection available in the current literature, in order to produce a set of recommendations for building a new model for the supplier selection process in the aerospace sector. To achieve this, two supplier selection models were critically reviewed, one of which is currently implemented in an aerospace industry and the other one is a theoretical model. A survey on global sourcing and supplier selection process containing 25 questions on various aspects of st rategic sourcing was also carried out in order to identify the different characteristics that influence sourcing decisions. Supplier selection methods: Supplier selection methods or techniques are the models which are used by decision makers to conduct the supplier selection process. They act as supporting tools for the selection process. The selection of an appropriate method is essential for the overall selection process and can significantly influence the outcome of the selection results (Li et al., 1997). There are number of supplier selection methods available in the literatures. Mathematical Programming (MP): MP allows the formulation of the decision problem in the form of a mathematical objective function which needs to be minimised or maximised depending on the objective function by varying the values of the variables. It is an optimization method which selects a number of suppliers in order to maximize either a single criteria or multi criteria objective function subjected to supplier or buyer constraints (DeBoer et al., 2001). Talluri and Narasimhan (2003) used mathematical programming in the form of a linear programming model to first minimise and then maximise the performance of the suppliers against the best target measures set by the buyers, thus providing a wide-ranging understanding of supplier performance. The authors applied this model considering a set of six suppliers to a Fortune 500 Pharmaceutical company in the process of implementing a JIT system. They regarded price, quality and delivery as the top three criteria for evaluating the suppliers. One of the key features of this max-min approach was that it could identify a set of suppliers with identical characteristics, thus providing the buyer with effective alternates to make their final decision. For the supplier selection problem Ng (2008) developed a weighted linear programming model with an objective function of maximizing supplier score. He implemented the model considering 18 suppliers to a manufacturing firm producing agriculture and c onstruction equipment. He included five criteria namely quality, supply variety, delivery, distance and price. In order to maximise the revenue function Hong et al. (2005) developed a mixed integer linear model to optimize the number of suppliers and order quantity. He applied the model to the supply chain of the agriculture industry in Korea as the customer demand varied seasonally over a period of time. Similarly OBrien et al. (2001) created a mixed integer non-linear model to optimize the allocation of products to suppliers thus minimizing the annual purchasing costs. Narasimhan et al. (2006) and Wadwa et al. (2007) constructed theoretical multi-objective programming models to optimize supplier selection and order quantity and to minimise lead time, price and number of rejects. Karpak et al. (1999) constructed a goal programming model and applied it to an international manufacturing firm to minimise costs and maximise quality and delivery reliability for selection of suppliers an d allocation of products between them. The authors considered cost, quality and delivery reliability as the criteria for supplier evaluation. On one hand Mathematical programming is advantageous as compared to the other approaches as it takes into account all the constraints during the formulation of the problem. Hence it is much easier to work when a large number of constraints are considered. It can also be used for multiple supplier selection as the current situation can be taken into account in an MP model. On the other hand some of the drawbacks of using an MP model are that it often only considers the more quantitative criteria neglecting the qualitative criteria which are important in supplier selection especially when the goal is to build supplier partnership. Most of the theoretical MP models are complicated to build for the supplier selection problem, due to the large number of variables, but as it can be seen from the above mentioned examples, they can be implemented in an industry as they can be simulated and solved by computers. They are not considered as the most effective method for vendor evaluation as they do not take into account qualitative factors and are incapable of performing a qualitative analysis which is an important aspect of the supplier selection process, thus limiting their use. Data Envelopment Analysis (DEA): The concept of DEA is constructed on the basis of calculating the efficiency of the decision alternatives or suppliers. The DEA is a non-parametric method the measures the efficiency without specifying the form of the production function or the weights of different inputs and outputs. The efficiencies are evaluated on the basis of benefits as output and cost as the input criteria (DeBoer et al., 2001). The efficiency of a supplier can be defined as the ratio of the weighted sum of the suppliers outputs to the weighted sum of his inputs, thus the DEA method calculates the most favourable set of weights for each supplier alternative classifying them into efficient and inefficient suppliers. The favourable set of weights that are calculated maximise the supplier efficiency ratings without altering its own rating or making the other suppliers efficiency ratings more than one (DeBoer et al., 2001). In order to measure the efficiency of alternative suppliers Braglia and Petroni (2000) applied the DEA method by proposing nine evaluating factors to measure the supplier ratings. The authors applied their proposed methodology to the supplier selection process of a middle-sized company manufacturing bottling machinery to test its efficiency. They also calculated the Cross efficiencies in which the weights chosen for a particular supplier can be applied to the weights of the inputs and outputs of the other suppliers as well as Maverick index which is the percentage relative difference between cross efficiency and simple efficiency in order to avoid the selection of false positive supplier. Talluri and Barker (2002) and Talluri and Sarkis (2002) applied DEA to evaluate suppliers, manufacturers and distributors as a three phase approach for a logistics distribution network. They also employed the DEA to measure the performance of the suppliers using six evaluating factors having two inp uts and four outputs. Ross et al. (2006) evaluated the supplier performance with respect to the performance attributes of both buyer and supplier by using DEA. The author carried out three sensitivity analysis; the first one computed supplier efficiency scores without taking into account the evaluation teams and the buyers weights. The second analysis considered the evaluation taking into account the teams preferences and the third analysis considered the buyers preference. Liu et al. (2000) constructed a DEA model to evaluate the overall performance of a supplier considering three inputs namely price index, delivery performance and distance factor and two outputs which were supply variety and quality. The authors applied the DEA model to a firm manufacturing agriculture and construction equipment containing a multi modal assembly line. The model could select suppliers with a high supply variety, thus reducing the number of suppliers. Seydel et al. (2006) developed a DEA model to evaluate technology suppliers considering three factors. He included amount of know-how transfer as a qualitative factor in the model. The author developed a five point scale to rank the suppliers in term of the qualitative factor. The DEA method provides a means to evaluate and select suppliers on the basis of their performance over a period of time. It compares supplier performance in a multi criterion setting thus allowing the purchasing firm to evaluate each suppliers performance relative to the performance of the best supplier in the market by calculating the efficiency measures. Observed supplier performance data is used in a DEA method, thus the purchasing firm does not have to calculate its own utility functions as is required in the other techniques. Some of the limitations of the DEA approach are that its focus is not on selection an optimal supplier as the other mathematical programming models; hence it cannot be used if the purchasing firm requires the selection of an optimal supplier. The DEA model also makes some assumptions like any other supplier selection model thus limiting its use. (Garfamy et al., 2006) Evolution of the Analytic Hierarchy Process (AHP): Linear Weighting Model: Weights are assigned to the criteria with the largest weight corresponding to the highest priority, in a linear weighted model. The ratings of the criteria are then multiplied with their respective weights and the sum of weights is assigned to each supplier, thus the supplier with the highest overall rating can be selected. There are a few imprecisions in the rating mechanism such as difficulty to determine the score of a supplier on a criterion or importance of some criterion with a high degree of precision. To overcome these imprecisions the use of analytic hierarchy process (AHP) was proposed (DeBoer et al., 2001). Analytic Hierarchy Process: The AHP is a decision making method first introduced by Saaty (1980) which prioritizes alternatives or suppliers when considering multiple criteria, thus allowing the decision maker to restructure complex problems in the form of a set of integrated levels or a hierarchy. It is one of the most commonly applied methods in practice as it incorporates qualitative as well as quantitative criteria and is relatively simple to understand. Various adaptations of AHP have been developed since its introduction. Muralidharan et al. (2002) developed an AHP model consisting of five stages to rate and select suppliers considering nine criteria. Some of the major criteria that the author considered were quality, delivery, price and technical ability. The model was then applied to the supplier selection process to evaluate six suppliers of a leading organization manufacturing bicycles. Liu and Hai (2005) created an AHP model and used Noguchis voting and ranking system thus allowing each manager to determine the order of criteria instead of weights for the selection and evaluation of suppliers. They used a six step process for supplier evaluation and considered eight criteria in their analysis, some of them being quality, responsiveness, delivery, technical capabilities etc. The authors applied this model for selecting one of ten suppliers for the Umbrella Scheme of Malaysias furniture industry. Chan and Chan (2004) constructed an AHP model considering six criteria namely cost, delivery, flexibility, innovation, quality and service with twenty sub-factors among them. They applied the model to the supplier selection process of a leading company that manufactures and supplies semiconductor assembly equipment assuming that the supplier had to be chosen for a critical product. The relative priority ratings were calculated based on customer or buyer requirements. Hou et al (2007) developed a decision support system based on AHP in a mass customization environment considering internal and external factors to meet market requirements. The author applied the model to the selection process of a subsidiary company of a local Chinese printer manufacturer. Chan (2003) created an AHP based interactive selection model which determined the relative importance of evaluating criteria without being subjected to human judgment. The AHP model can also be integrated with other supplier selection models in order to achieve optimized selection results. Ramanathan (2007) suggested that the qualitative and quantitative information gained from the total cost of ownership model and AHP model can be utilized to evaluate the performance of a supplier using the DEA method. The author considered the costs from total cost of ownership as inputs and the weights gained from the AHP method as outputs. Sevkle et al. (2007) applied the AHP-DEA integrated method to solve the supplier selection problem of a major Turkish TV manufacturer BEKO, in which he used AHP to derive local weights from a given comparison matrix and summed up the local weights to get the overall weights. In order to calculate the efficiency scores of all the suppliers DEA was used on the decision making units. Percin (2006) applied integrated AHP-GP method, where AHP was used to measure the priority weightings of alternate suppliers considering twenty evaluating factors. The author used the weightings obtained by AHP Goal programming method as the coefficients for five object ive functions. The integrated model was used to optimize the order quantity from the most appropriate supplier considering the capacities of the suppliers. Mendoza et al. (2008) offered an integrated AHP- GP model in order to reduce a large number of potential suppliers to a manageable figure. He ranked the alternatives considering five evaluating criteria to optimize the order quantity. Xia and Wu (2007) applied the AHP model to calculate the performance scores of potential suppliers. The authors then applied the scores as coefficients of one of the four objective functions in a multi-objective mixed integer programming model. The model was developed in order to determine the optimal number of suppliers and to select the best set of suppliers. Some of the advantages of AHP method are as follows (Chan et al., 2003) The system can be represented in a hierarchical manner to explain the changes in priority and its effect at upper and lower levels. The desired performance of the supplier is characterized by hierarchical selection criteria viz. the management of the suppliers is better if the suppliers performance is evident to the buyer. It utilizes multiple paired comparisons of criteria to rank order alternatives and it is the most exceptional Multi-criterion decision making approach. Efficiently progresses through modular construction and final assembly of modules than those assembled as a whole, this is known as hierarchical assembly of natural systems. Identifies the key elements assisting in making more accurate business decisions and is a structured method which obtains information from target respondents (decision makers or experts). It provides information regarding the structure and function of a system in the lower levels of the hierarchy and gives the outline of the criteria and their purposes in the upper levels. Limitations on the elements in a level are best denoted in the next higher level to ensure they are satisfied. It has stability and flexibility, stability as small changes have small effects and flexible in the sense that the performance is not hampered if there are any additions to a well structured hierarchy Disadvantages: (Chan et al., 2003) Most of the supplier selection problems do not have a single hierarchy. Utilization of this statistical method is complicated for most of the users and this makes the process unmanageable. It is not cost effective to procure the essential information i.e. due to lack of information /willingness to compare two alternatives with respect to some criterion the supposition of comparability is invalid. To reach an agreement with the team members by reviewing the models is time consuming. The presumption that the relative importance of criteria affects the suppliers performance is definite which cannot effectively take into account the risk and uncertainty in assessment of suppliers potential performance. Analytic network process (ANP): Sarkis and Talluri (2000) suggested the use of analytic network process, which was a more sophisticated version of the AHP method. The authors believed that the supplier evaluating factors could influence each other and this interdependency needed to be considered in the process. They applied the ANP process to evaluate and select suppliers in a company manufacturing custom-designed high technology metal-based products, considering organizational factors and strategic performance matrix. The model included seven evaluating criteria namely cost, quality, flexibility, delivery time etc. also considering their interdependencies. Bayazit (2006) implemented an ANP model considering ten evaluating criteria. Some of the important criteria included were on time delivery, quality, flexibility and delivery lead time. He classified the criteria into supplier performance and capabilities clusters and the interdependencies among them were formulated by considering each cluster as a controlling fa ctor for a pair wise comparison matrix. Demirtas and Ustun (2008) developed an integrated model in which they used ANP to evaluate the performance of potential suppliers considering 14 criteria. The weights were then considered in one of the three objective functions of a multi-objective mixed integer programming model. Similarly the authors integrated the ANP and the GP methods of supplier selection and evaluation in 2009. The only difference to the previous model was that there were four goals in the GP model. Gencer et al. (2007) developed ANP model considering various evaluating criteria. He classified them into three clusters to take into account their interrelationships to evaluate and select the most appropriate supplier. Some major advantages of ANP process over AHP are that ANP provides with additional insight as most of the real world supplier selection problems have interdependencies among the evaluating criteria. It also incorporates both qualitative as well as quantitative factors which are important in supplier selection. The ANP method can deal with various uncertainties and complexities as it makes use of ratio scales to incorporate a variety of interactions. In spite of the advantages, the ANP method does have a few limitations as it is a very complex method and requires additional effort and time as compared to AHP. Fuzzy Set Theory: The fuzzy set theory is used to model uncertainty and imprecision in the supplier selection situation. Fuzzy set systems make use of linguistic rules which are very well suited to describe the behavior of practical problems. In most of the real world applications, fuzzy rules are created by the decision makers with a few input variables. When the number of input variables increases, the possible number of fuzzy rules for a particular system increases exponentially. It is rather difficult for the decision maker to generate a complete set of rules to assess the supplier selection system (Chan et al., 2006). Chan et al. (2006) presented a hierarchy model based on the fuzzy set theory which could deal with both quantitative and qualitative criteria. The author used linguistic values to assess the ratings and the weights for the evaluation factors. The ratings were arranged in triangular fuzzy numbers. They created a hierarchical structure of the decision problem and applied the model to a high technology manufacturing company to select a suitable supplier to supply material for key components of a new product. Sarkar and Mohapatra (2006) used a fuzzy set method to eliminate the imprecision in a number of subjective characteristics of suppliers. The authors evaluated and selected the suppliers on the basis of performance and capabilities as the two major measures for evaluation. They considered a hypothetical case to exemplify their model by considering a pool of ten suppliers and the goal being to reduce that number and select the best two suppliers. Kahraman et al. (2003) applied the integrated fuzzy AHP approach to select the most appropriate supplier for the biggest white goods manufacture in Europe to supply the plastic part scroll housing for their new model of aspirators. In this model the decision makers could specify their preferences in terms of linguistic variables regarding the priority of each evaluating criteria. Chan and Kumar (2007) also applied a fuzzy AHP methodology for selection of suppliers. The authors used triangular fuzzy numbers and fuzzy synthetic extent analysis methods to choose the final priorities of different criteria. The authors applied the model to the supplier selection process of a manufacturing company to select the best global supplier for one of their critical parts used in the assembling process. The criteria considered in the model for evaluation were overall cost, quality of product, service performance, supplier profile and risk factors. Amid et al. (2006) formulated an integrated fuzzy multi-objective linear programming model which took into account the vagueness and imprecision of the input data in order to optimize the order quantity. The author developed an algorithm to solve the model which incorporated three objective functions with different weights. They considered a hypothetical case to select three suppliers for supplying a new product to a market. The purchasing criteria considered for the model were net price, quality, service and capacity. The author also formulated a fuzzy multi-objective mixed integer programming model which was similar to the earlier model but it also took into account the quantity discount. The price discount was directly proportional to the quantities ordered (Amid et al, 2006). One of the primary advantages of using fuzzy set theory for supplier selection is that it makes use of linguistic variables, which are highly beneficial when the performance values cannot be expresses in terms of means of the numerical values. Thus, taking into consideration the uncertainty and imprecision of the quantitative data gathered by the purchasing company or provided by the supplier. It is beneficial and easier to use linguistic variables instead of numerical values while assessing potential suppliers with respect to criteria and weights. A modified fuzzy set theory is capable of handling both qualitative as well as quantitative data ratings and is flexible in use, which is an added advantage (Chan et al, 2006). Some of the disadvantages of fuzzy set theory are that the analysis is based on the theory and not exploratory data; hence validation of the data may be required. It is a subjective methodology, thus justification for each step is necessary. As the number of variabl es increase the complexity increases, thus requiring a number of procedures in the sub-systems of the methodology. Other Methods: A number of other methodologies exist for the supplier selection problem such as artificial intelligence and expert systems which includes case based reasoning (Choy et al, 2005; 2002; Humphreys et al, 2003) and Bayesian belief networks (Kreng et al, 2003). Multi-criteria decision methods which include outranking methods (DeBoer et al, 1998; Dulmin et al, 2003), judgmental modeling (DaSilva et al., 2002; Naude and Lockett, 1993), interpretive structural modeling (Mandal and Deshmukh, 1994) and categorical methods (Houshyar and Lyth, 1992). Multivariate statistical analysis that incorporates structural equation modeling (Lin et al., 2005; Tracey and Tan, 2001), Factor analysis (Krause et al., 2001; Tracey and Tan, 2001) and confidence interval approach (Muralidharan et al., 2001). Group decision methods (Han and Ahn, 2005; Mandal and Deshmukh, 1994) and multiple integrated methods also exist for supplier selection. All the methods that are utilized for selections of suppliers have their own advantages and disadvantages. No method can be said to be the perfect method which covers all aspects of the entire selection process. Modifications and improvements can be made to every method in according to the requirements of the decision makers. The selection process can be improved by integrating different techniques in order to negate the limitations of the techniques taken individually. Considering this procedure, the fuzzy integrated AHP model and the DEA integrated ANN model are comparatively the best combination of methods that can be implemented for supplier selection. Supplier Selection Criteria: Evolution of supplier selection criteria: A number of criteria need to be considered for the supplier selection decision making process which makes the selection of suppliers a complicated practice. Since the early 1960s, practitioners and academics have been focusing on the analysis of supplier selection criteria and measurement of supplier performance. Dickson et al, (1966) suggested From the purchasing literature is fairly easy to abstract a list of at least 50 distinct factors that are presented by various authors as being meaningful to consider in a vendor selection decisionÂ?. In his work he carried out a survey to identify the most important criteria required for the selection of suppliers. The author came up with 23 criteria and their relative importance for vendor selection. The following table summarizes the 23 criteria and their level of importance. Weber et al. (1991) conducted a similar study on the bases of the 23 criteria identified by Dickson (1966). The authors reviewed and classified 74 related articles appearing between 1966 and 1990. Their study provided a clear indication of the issues concerning selection of suppliers. Both the studies indicated net price, quality, delivery and production facility and capacity as the top 4 criteria for supplier evaluation. These two studies were the primary studies done on supplier selection criteria and were the bases of a number of papers in the forthcoming years. A number of changes at a profound level have taken place in the business environment, including purchasing and procurement since Weber et al.s work in 1991. The basic definitions of Dicksons 23 criteria have undergone change and expansion and new criteria have emerged due to a substantial growth in business and supply chain needs. Dickson (1966) defined net price as price offered by each vendor including discounts and freight charges. In the development of the net price criteria, the term net price had been replacement by the term cost which includes a number of costs such as fixed cost, inventory costs, ordering costs, supplier costs and costs associated with quality, after-sales and technology (Current and Weber, 1994). The term total cost of ownership has also become important in recent times which include not only the purchasing price but also purchasing related costs (Bhutta et al, 2002). The delivery criterion was defined by Dickson (1966) as the ability of each vendor to meet specified delivery schedules. The delivery criterion has now been developed to incorporate lead time, cycle time, shipment quantity and quality, delivery capacity etc (Karpak et al, 1999). According to Dickson quality was defined as the ability of each vendor to meet quality specifications consistently. The quality criterion has now been extended to include inspections and certain specifications such as the ISO9001 system (Lee et al, 2003) In addition to the evolution and development of the basic criteria a number of new criteria have emerged in literature from various authors. Some of the new criteria are flexibility, which includes process and production flexibility, response to change, responsiveness to customer needs (Ghodsypour et al, 2001), flexibility to change the order and order quantity and ability to respond to fluctuating demand (Verma et al, 1998). A product design and development criterion consists of commitment to continuous improvement, product development and improvement, design capabilities and continuous improvement in product and process (Chan et al, 2003). Supplier relationship is another criterion that has gained importance in recent years due to integration of various sections of supply chain. Supplier relationship has two aspects, strategic and tactical. The criterion can be sub divided into 4 sections namely strategic long term relationship, tactical long term relationship, strategic short term relationship and tactical short term relationship. Due to the growth in the businesses, buying firms prefer to integrate the suppliers in their supply chain, thus forming a strategic long term alliance with their supplier

Love Song of J. Alfred Prufrock Essay example -- T.S. Eliot Lust Sex R
Love Song of J. Alfred Prufrock The pursuit of youth, of sex, of â€Å"yellow fog that rubs its back upon the window panes,†some pursue this their whole lives, a bachelor looking in the corners of streets and bars for a bit of youth and company. This is the Love Song of J. Alfred Prufrock by T.S. Eliot, 1917. It is the song and love story of men who search for their lover in places absent of love and instead only finds lust. Those who only find lust in these lonely places eventually become old, as the speaker of the poem realizes. The only argument in this poem is that of a man much past his prime, arguing to himself whether to retire the chase; the author uses logos, ethos and pathos when arguing to himself, and you, about giving up the Darwinian chase. The author of this poem is T.S. Eliot a modern poet who is a contemporary of Hemingway and Fitzgerald. Much of his work comes from post World War I, a period which was filled with excess and disillusionment with humanity and our ability to create and control civilization. The greatest war in the history of the world up to that point had just been fought. Millions died and the World with all its sadness could do nothing more then try and fill itself with wine and lust. The poem deals partly with this matter, mostly with lust and pursuit of women to find happiness in a world full of dingy sadness. The author addresses himself in this poem. Much similar to you looking at yourself in the mirror and speaking to yourself; asking questions and answering them. A sense of this is achieved in the first stanza when he refers to â€Å"you and I†meaning the self seen by others and the self he perceives. Yet this rhetorical self is juxtaposed next to an ... ...ser to death to argue that he is indeed growing older that because he has fear of death he realizes his youth is now gone. His fear is pathos and an appeal to himself that he is getting older. Remember that he is in discussion with himself and you are the audience to his personal monologue, he does not have to convince you that he is growing old but himself, the man in the mirror. Pathos or the poet’s emotional appeal is that he is afraid of death and simply that means he is growing older. Those who find lust in instead of love in youth find themselves in the situation that T.S. Eliot finds himself in. That situation is growing old and still behaving as a lustful youth wondering what to do and reasoning with yourself over your wasted pursuit of women and whether to continue the chase or give into old age and â€Å"wear the bottoms of my trousers rolled.â€

As I Grow Older I Pay Less Attention to What Men Say :: Teaching Education School Essays
As I Grow Older I Pay Less Attention to What Men Say During our careers as students, many professors, many peers, and many mentors will try to tell us the many different ways that we â€Å"should†teach. One person is going to tell us how some thing should be done, while someone else is going to insist that it be done differently. However, if you just sit back and actually watch these professors and these mentors, you are going to find that they sometimes forget to head the words of Jesus and practice what they preach. Through out my career as a student I have came across teachers who make learning fun and have a genuine love for teaching. However, I have also encountered those teachers who make you want to pull the fire alarm, just so you can avoid their endless ramblings. It is a teacher’s responsibility to keep students interested and eager to learn. If a subject intrigues a child they will want to learn more about it, and what they learn will stay with them for a life time. Sadker and Sadker (2003) identify Idealists as teachers who: know the content very well, view teachers as role models, values each student as an individual, and who have very few discipline problems that result in trips to the principals office. The above are reasons that I would like to take and Idealist approach to teaching. I want to become a teacher because I want to be able to turn on CNN one day and say, â€Å"you see that young man boarding Apollo 45, I showed him that science could be fun.†Being a teacher is comprised of many duties and responsibilities. From day one we must take into account all of the things necessary for becoming a good teacher. The various components of an organized classroom, the different ways of motivating our students, the appropriate ways of disciplining our students, the different styles we will incorporate into the way we teach and the leadership styles necessary for being an effective mentor. First of all the organization of ones classroom is one of the most important factors that we must take into account. We must plan exactly how we want the room to look, and more importantly how we want it ran. A classroom for an elementary teacher needs to be bright and cheerful.

If Martin Luther King Were Ali :: essays research papers
Martin Luther King was such an inspirational leader because he appealed to not only the black population, but he appealed to all people who believed in equality and freedom. He was viewed as a clean cut, all round good man, and unlike other leaders in the movement for racial equality, did not have un-orthodox, radical views. Since people did not see him as a threat, but as a peaceful man, leading a movement, he was easy to support. For example: People are more likely to agree with a man who explains something in a non-violent, nice way, than someone who uses mud slinging, name calling, and violence to express a view.      I believe that if Martin Luther King were alive today, that he would still continue to inspire, and lead the civil rights movement the way he did when he was alive. Martin Luther King was not just a leader of blacks, looking for equality, but as a leader of a revolution that affected all races and genders. No one like him has made such a difference in America since him, so nobody would honestly know what kind of difference Dr King would make today in the 90’s. However, in such a racial tension filled decade, a leader like Dr King, would most likely defend the rights of the rightless, and be the voice of the voiceless, as he was more than 30 years ago.          I think that Martin Luther King would make a tremendous amount of change in cases of mistreated Americans. Incidents such as the Rodney King beating, and Reginald Denny. Along with the cases of Abner Louima and Amadou Diallo. They were all classified as racial crimes, and all created a large amount of racial tension. Dr King was very good at defusing tension like that. He never preached radical opinions about violence or the such, just about all races getting along. Especially during the Rodney King riots in California, Martin Luther King could have made a huge difference. Instead of speaches of black pride that maybe fueled tension, I believe Dr. King would have preached Equality, and unification instead.      I somewhat believe that the death of Dr. King was a conspiracy. So many questions about the assassination have not been answered, and the ones that have, are filled with loopholes. I think that the government knows more than they tell us they do, but maybe not knowing certain things is better.

Argumentative Essay Against Euthanasia Essay
Introduction Euthanasia is the practice of deliberately killing a person to spare him or her from having to deal with more pain and suffering. This is always a controversial issue because of the moral and ethical components that are involved. This paper will discuss the arguments against euthanasia. Discussion Euthanasia is clearly against the Hippocratic Oath that all doctors have to fulfil. This oath basically states that doctors must never be involved in the killing of people because after all, they have been trained to ensure that people are able to recover from their diseases and injuries. Doctors are the ones whom people entrust their lives whenever there is something wrong with their health. Thus, it is the responsibility of the doctors to always do the best they can to help people live and enjoy their lives (Cavan 48). If their patients die under their supervision, the doctors can accept this for as long as they know and can prove that they really did their best and exhausted all possibilities to ensure the survival of the patients. There are just certain instances where the disease or the injury of the patients has become so serious that it is already difficult to treat and make the patients recover. In these cases, it is unfair to blame the doctors for the death of the patients. The Hippocratic Oath helps the doctors to realize how important their responsibilities are to the people in terms of their health. This oath also provides an assurance to the people that they can trust their doctors and be assured that they will do whatever is necessary to help them deal with their health problems. If euthanasia becomes legalized, then the effectiveness of the Hippocratic Oath will be negated and the doctors can have the option of immediately resorting to euthanasia especially in difficult cases instead of trying their best until the very end. Another argument against euthanasia is that it is essentially homicide because the doctors will kill the patient even if it has been approved by the patient himself or the family of the patient. Euthanasia is not that different from murder because they both involve killing a person. The only difference is that in euthanasia, there is mercy and consent involved while in murder there is none (Tulloch 82). If murder is prohibited by law because people take matters into their own hands and kill others, then euthanasia should also be banned because doctors take matters into their own hands and kill their patients even if there is consent from the patients and their families or relatives. Lastly, the continued improvements and innovations in the field of medicine and health care make euthanasia illogical to be implemented as an option. The reason why medical experts continue to work hard to come up with improved medical technologies, medicines and treatment methods is that they want to make sure that the sick people are able to recover faster and healthy people become even healthier. All of these efforts are being done to make the society become more productive due to the presence of healthy and strong people (McDougall 26). Thus, doctors will not have an excuse for not doing their best for their patients as they already have access to the best medical technologies, medicines and treatment methods that will prevent them from having to resort to euthanasia as the only option. Conclusion There is no doubt that euthanasia needs to be banned as based on the three arguments discussed above, it does not deserve a place in human society. Doctors must never give up on their patients no matter how hopeless the situation might be. They must exhaust all options to give their patients a fighting chance to survive and
