Reaction to Beloved :: essays research papers
Reaction To Beloved à à à à à The movie Beloved was a tale of a woman who is so devastated by the evil of slavery. Therefore she is willing to kill her toddler daughter rather than allow her to be taken back into the horror. This murderous act proves itself to be a choice, which only further enslaves her soul as her daughterââ¬â¢s ghost haunts her life. The movie was set in the 1800ââ¬â¢s. Sethe is a pregnant slave on a Kentucky plantation named Sweet Home. She was under control by a violent slave master. To me there is no reason or excuse for this kind of evil. The enslavement and brutal treatment of our fellow human beings is a spiritual scar. à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à When Sethe gives birth to Beloved and is reunited with her children in Ohio. The happiness of this reunion is turn into a tragic event as she sees her former master riding up to the house with the local sheriff. Sethe knows that he is coming back to take her children back into slavery, she runs into the shed, cuts the throat of her two year old daughter, Beloved, and hits her sonsââ¬â¢ heads with a shovel. Her sons didnââ¬â¢t die but beloved did. Soon after the tragic event the spirit of Beloved haunts Setheââ¬â¢s house. The scene of seeing Sethe kill Beloved is very disturbing to witness. The ghostly tantrum of Beloved comes back over and over again to disrupt Setheââ¬â¢s home. Her two sons become very scared by the haunts of Beloved. Setheââ¬â¢s younger daughter, Denver becomes calm with her mother and the ghost, and she never leaves the house and yard. Sethe also becomes ok with the ghost presence in the house. She keeps denying that she did anything wrong by killing Beloved. So she feels that she doesnââ¬â¢t need any help.à à à à à à à à à à à à à à à This is often the way evil take over our lives. Rather than having the courage to face the evil we suffer , as Sethe did she affected her own children with this violence. Sethe became in denial with her responsibility. She accepted the pain of her guilt and shame with a lie towards her dignity. She felt everything was right and didnââ¬â¢t want to ask for forgiveness and victory over the evil. But soon a physical form of Beloved comes to Setheââ¬â¢s house. The girl who act as Beloved is real and demanding like a spoiled child.

It is concerned with the software management processes that examine the area of software development through theà development models, which are known as software developmentà life cycle. It represents five of the development models namely, waterfall, Iteration, V-shaped, spiral and Extreme programming. These models have advantages and disadvantages as well. Therefore, the main objective of this research is to represent different models of software development and make aà comparison between them to show the features and defects of each model. Keywords: Software Management Processes, Softwareà Development, Development Models, Software Development Lifeà Cycle, Comparison between five models of Software Engineering. increased recently which results in the difficulty ofà enumerating such companies. During the previous fourà decades, software has been developed from a tool used forà analyzing information or solving a problem to a product inà itself. However, the early programming stages haveà created a number of problems turning software anà obstacle to software development particularly thoseà relying on computers. Software consists of documents andà programs that contain a collection that has beenà established to be a part of software engineeringà procedures. Moreover, the aim of software engineering isà to create a suitable work that construct programs of highà quality. 1. Introduction Computer Science No one can deny the importance of computer in our life,à especially during the present time. In fact, computer hasà become indispensible in todayââ¬â¢s life as it is used in manyà fields of life such as industry, medicine, commerce,à education and even agriculture. It has become anà important element in the industry and technology ofà advanced as well as developing countries. Now a days,à organizations become more dependent on computer inà their works as a result of computer technology. Computerà is considered a time- saving device and its progress helpsà in executing complex, long, repeated processes in a veryà short time with a high speed. In addition to usingà computer for work, people use it for fun andà entertainment. Noticeably, the number of companies thatproduce software programs for the purpose of facilitatingà works of offices, administrations, banks, etc, has Theories Computer Function Client Problems The Software engineering Tools and techniques to solve problems Fig. 1 Explanation of software engineering conception.

A software process model is an abstract representation of a process. It presents a description of a process from some particular perspective as: The pure waterfall lifecycle consists of several nonoverlapping stages, as shown in the following figure. The model begins with establishing system requirements andà software requirements and continues with architecturalà design, detailed design, coding, testing, and maintenance. The waterfall model serves as a baseline for many otherà lifecycle models. 1. 2. 3. 4. Specification. Design. Validation. Evolution. General Software Process Models are 1. Waterfall model: Separate and distinct phases of specification and development. 2. Prototype model. 3. Rapid application development model (RAD). 4. Evolutionary development: Specification, development and validation are interleaved. 5. Incremental model. 6. Iterative model. 7. Spiral model. 8. Component-based software engineering : The system is assembled from existing components. System Requirements Software Requirements Architectural Design Detailed Design Coding There are many variants of these models e.g. formal development where a waterfall-like process is used, but the specification is formal that is refined through several stages to an implementable design[1]. Testing Maintenance Fig. 2 Waterfall Model[4]. 3. Five Models A Programming process model is an abstract representation to describe the process from a particular perspective. There are numbers of general models for software processes, like: Waterfall model, Evolutionary development, Formal systems development and Reusebased development, etc. This research will view the following five models : 1. Waterfall model. 2. Iteration model. 3. V-shaped model. 4. Spiral model. 5. Extreme model. These models are chosen because their features correspond to most software development programs. Requirements Definition System and Software Design Implementation and Unit Testing Integration and System Testing 3.1 The Waterfall Model The waterfall model is the classical model of softwareà engineering. This model is one of the oldest models and isà widely used in government projects and in many majorà companies. As this model emphasizes planning in earlyà stages, it ensures design flaws before they develop. Inà addition, its intensive document and planning make ità work well for projects in which quality control is a major Operation and Maintenance Fig. 3 Waterfall model[2]. The following list details the steps for using the waterfall IJCSI International Journal of Computer Science Issues, Vol. 7, Issue 5, September 2010 ISSN (Online): 1694-0814 www.IJCSI.org model: 1 System requirements: Establishes the componentsà for building the system, including the hardwareà requirements, software tools, and other necessaryà components. Examples include decisions onà hardware, such as plug-in boards (number ofà channels, acquisition speed, and so on), and decisionsà on external pieces of software, such as databases orà libraries. 2 3 Software requirements: Establishes the expectationsà for software functionality and identifies which systemà requirements the software affects. Requirementsà analysis includes determining interaction needed withà other applications and databases, performanceà requirements, user interface requirements, and so on. Architectural design: Determines the softwareà framework of a system to meet the specificà requirements. This design defines the majorà components and the interaction of those components,à but it does not define the structure of eachà component. The external interfaces and tools used inà the project can be determined by the designer. 4 Detailed design: Examines the software componentsà defined in the architectural design stage and producesà a specification for how each component isà implemented. 5 Coding: Implements specification. 6 7 the detailed starting coding. There is no overlap between stages. Inà real-world development, however, one can discover issuesà during the design or coding stages that point out errors or gaps in the requirements. The waterfall method does not prohibit returning to anà earlier phase, for example, returning from the design phaseà to the requirements phase. However, this involves costlyà rework. Each completed phase requires formal review andà extensive documentation development. Thus, oversightsà made in the requirements phase are expensive to correctà later. Because the actual development comes late in the process,à one does not see results for a long time. This delay can beà disconcerting to management and customers. Many peopleà also think that the amount of documentation is excessiveà and inflexible. Although the waterfall model hasà instructive because it emphasizesà project development. Even if oneà model, he must consider each ofà relationship to his own project [4]. ï⠷ 1. 2. 3. design Testing: Determines whether the software meets theà specified requirements and finds any errors present inà the code. Maintenance: Addresses problems and enhancementà requests after the software releases. In some organizations, a change control board maintainsà the quality of the product by reviewing each change madeà in the maintenance stage. Consider applying the fullà waterfall development cycle model when correctingà problems or implementing these enhancement requests. In each stage, documents that explain the objectives andà describe the requirements for that phase are created. At the end of each stage, a review to determine whether theà project can proceed to the next stage is held. Yourà prototyping can also be incorporated into any stage fromà the architectural design and after. Many people believe that this model cannot be applied toà all situations. For example, with the pure waterfall model,à the requirements must be stated before beginning theà design, and the complete design must be stated before 96 4. 5. 6. ï⠷ 1. 2. 4. 5. 6. 7. ï⠷ its weaknesses, it isà important stages ofà does not apply thisà these stages and its Advantages : Easy to understand and implement. Widely used and known (in theory!). Reinforces good habits: define-before- design, design-before-code. Identifies deliverables and milestones. Document driven, URD, SRD, â⬠¦ etc. Published documentation standards, e.g. PSS-05. Works well on mature products and weak teams. Disadvantages : Idealized, doesnââ¬â¢t match reality well. Doesnââ¬â¢t reflect iterative nature of exploratory development. 3. Unrealistic to expect accurate requirements so early in project. Software is delivered late in project, delays discovery of serious errors. Difficult to integrate risk management. Difficult and expensive to make changes to documents, â⬠swimming upstreamâ⬠. Significant administrative overhead, costly for small teams and projects [6]. Pure Waterfall This is the classical system development model. It consists of discontinuous phases: 1. 2. 3. Concept. Requirements. Architectural design. IJCSI International Journal of Computer Science Issues, Vol. 7, Issue 5, September 2010 ISSN (Online): 1694-0814 www.IJCSI.org 4. 5. 6. Detailed design. Coding and development. Testing and implementation. Table 1: Strengths & Weaknesses of Pure Waterfall Strengths ï⠷ ï⠷ Minimizes planningà overhead since it can be done up front.à Structure minimizesà wasted effort, so ità works well forà technically weak orà inexperienced staff. Risk reduction spirals can be added to the top of theà waterfall to reduce risks prior to the waterfall phases. The waterfall can be further modified using options such asà prototyping, JADs or CRC sessions or other methods ofà requirements gathering done in overlapping phases [5]. Weaknesses 3.2 Iterative Development ï⠷ Inflexible ï⠷ Only the final phaseà produces a nondocumentationà deliverable. ï⠷ Backing up to address mistakes is difficult. The problems with the Waterfall Model created a demandà for a new method of developing systems which couldà provide faster results, require less up-front information,à and offer greater flexibility. With Iterative Development,à the project is divided into small parts. This allows theà development team to demonstrate results earlier on in theà process and obtain valuable feedback from system users. Often, each iteration is actually a mini-Waterfall processà with the feedback from one phase providing vitalà information for the design of the next phase. In a variation of this model, the software products, which are producedà at the end of each step (or series of steps), can go intoà production immediately as incremental releases. ï⠷ Pure Waterfall Summary The pure waterfall model performs well for products withà clearly understood requirements or when working withà well understood technical tools, architectures andà infrastructures. Its weaknesses frequently make ità inadvisable when rapid development is needed. In thoseà cases, modified models may be more effective. ï⠷ 97 Modified Waterfall The modified waterfall uses the same phases as the pureà waterfall, but is not based on a discontinuous basis. Thisà enables the phases to overlap when needed. The pureà waterfall can also split into subprojects at an appropriateà phase (such as after the architectural design or detailed design). Table 2: Strengths & Weaknesses of Modified Waterfall Strengths ï⠷ ï⠷ ï⠷ ï⠷ More flexible than theà pure waterfall model. If there is personnelà continuity between theà phases, documentationà can be substantially reduced.à Implementation of easyà areas does not need toà wait for the hard ones. Weaknesses ï⠷ ï⠷ ï⠷ Modified Waterfall Summary Milestones are moreà ambiguous than theà pure waterfall. Activities performedà in parallel are subjectà to miscommunicationà and mistakenà assumptions. Unforeseenà interdependencies canà create problems. Fig. 4 Iterative Development. 3.3 V-Shaped Model Just like the waterfall model, the V-Shaped life cycle is aà sequential path of execution of processes. Each phaseà must be completed before the next phase begins. Testingà is emphasized in this model more than the waterfallà model. The testing procedures are developed early in theà life cycle before any coding is done, during each of theà phases preceding implementation. Requirements begin theà life cycle model just like the waterfall model. Before IJCSI International Journal of Computer Science Issues, Vol. 7, Issue 5, September 2010 ISSN (Online): 1694-0814 www.IJCSI.org development is started, a system test plan is created. The test plan focuses on meeting the functionality specified in requirements gathering. 98 Requirements The high-level design phase focuses on systemà architecture and design. An integration test plan is created in this phase in order to test the pieces of the softwareà systems ability to work together. However, the low-levelà design phase lies where the actual software componentsà are designed, and unit tests are created in this phase asà well. System Test Planning High Level Design Low Level Design The implementation phase is, again, where all codingà takes place. Once coding is complete, the path ofà execution continues up the right side of the V where theà test plans developed earlier are now put to use. ï⠷ Simple and easy to use. Each phase has specific deliverables. Higher chance of success over the waterfall modelà due to the early development of test plans during theà life cycle. Works well for small projects where requirements areà easily understood. Unit Test Planning Integration Testing Unit Testing Implementation Advantages 1. 2. 3. Integration Test Planning System Testing 4. Fig. 6 V-Shaped Life Cycle Model[7]. 3.4 Spiral Model The spiral model is similar to the incremental model, withà more emphases placed on risk analysis. The spiral modelà has four phases: Planning, Risk Analysis, Engineering andà Evaluation. A software project repeatedly passes throughà these phases in iterations (called Spirals in thisà model). The baseline spiral, starting in the planningà phase, requirements are gathered and risk isà assessed. Each subsequent spiral builds on the baselineà spiral. Requirements are gathered during the planningà phase. In the risk analysis phase, a process is undertakenà to identify risk and alternate solutions. A prototype isà produced at the end of the risk analysis phase. Software isà produced in the engineering phase, along with testing atà the end of the phase. The evaluation phase allows theà customer to evaluate the output of the project to dateà before the project continues to the next spiral. In the spiral model, the angular component representsà progress, and the radius of the spiral represents cost. Fig. 5 V-Model [3] ï⠷ Disadvantages 1. 2. Very rigid like the waterfall model. Little flexibility and adjusting scope is difficult andà expensive.à Software is developed during the implementation phase,à so no early prototypes of the software are produced. This Model does not provide a clear path for problemsà found during testing phases [7]. 3. 4. ï⠷ 1. 2. 3. Advantages High amount of risk analysis. Good for large and mission-critical projects. Software is produced early in the software life cycle. ï⠷ 1. 2. 3. Disadvantages Can be a costly model to use. Risk analysis requires highly specific expertise. Projectââ¬â¢s success is highly dependent on the riskà analysis phase. Doesnââ¬â¢t work well for smaller projects [7]. 4. IJCSI International Journal of Computer Science Issues, Vol. 7, Issue 5, September 2010 ISSN (Online): 1694-0814 www.IJCSI.org ï⠷ 1. Spiral model sectors Objective setting :Specific objectives for the phase are identified. 2. Risk assessment and reduction: Risks are assessed and activities are put in place to reduce the key risks. 3. Development and validation: A development model for the system is chosen which can be any of the general models. 4. Planning: The project is reviewed and the next phase of the spiral is planned [1]. 99 under which the system would produce win-lose or loselose outcomes for some stakeholders. 3. Identify and Evaluate Alternatives: Solicità suggestions from stakeholders, evaluate them with respectà to stakeholdersââ¬â¢ win conditions, synthesize and negotiateà candidate win-win alternatives, analyze, assess, resolveà win-lose or lose-lose risks, record commitments and areasà to be left flexible in the projectââ¬â¢s design record and lifeà cycle plans. 4. Cycle through the Spiral: Elaborate the win conditionsà evaluate and screen alternatives, resolve risks, accumulateà appropriate commitments, and develop and executeà downstream plans [8]. 3.5 Extreme Programming An approach to development, based on the developmentà and delivery of very small increments of functionality. Ità relies on constant code improvement, user involvement inà the development team and pair wise programming . It canà be difficult to keep the interest of customers who areà involved in the process. Team members may be unsuitedà to the intense involvement that characterizes agileà methods. Prioritizing changes can be difficult where thereà are multiple stakeholders. Maintaining simplicity requiresà extra work. Contracts may be a problem as with otherà approaches to iterative development. Fig. 7 Spiral Model of the Software Process[1]. ï⠷ WinWin Spiral Model The original spiral model [Boehm 88] began each cycle ofà the spiral by performing the next level of elaboration ofà the prospective systemââ¬â¢s objectives, constraints andà alternatives. A primary difficulty in applying the spiralà model has been the lack of explicit process guidance inà determining these objectives, constraints, and alternatives. The Win-Win Spiral Model [Boehm 94] uses the theoryà W (win-win) approach [Boehm 89b] to converge on aà systemââ¬â¢s next-level objectives, constraints, andà alternatives. This Theory W approach involves identifyingà the systemââ¬â¢s stakeholders and their win conditions, andà using negotiation processes to determine a mutuallyà satisfactory set of objectives, constraints, and alternatives for the stakeholders. In particular, as illustrated in theà figure, the nine-step Theory W process translates into theà following spiral model extensions: 1. Determine Objectives: Identify the system life-cycleà stakeholders and their win conditions and establish initialà system boundaries and external interfaces. 2. Determine Constraints: Determine the conditions Fig. 8 The XP Release Cycle ï⠷ Extreme Programming Practices Incremental planning: Requirements are recorded on Story Cards and the Stories to be included in a release are determined by the time available and their relative priority. The developers break these stories into development ââ¬Å"Tasksâ⬠. Small Releases: The minimal useful set of functionality that provides business value is developed first. Releases of the system are frequent and incrementally add functionality to the first release. IJCSI International Journal of Computer Science Issues, Vol. 7, Issue 5, September 2010 ISSN (Online): 1694-0814 www.IJCSI.org Simple Design: Enough design is carried out to meet theà current requirements and no more. Test first development: An automated unit testà framework is used to write tests for a new piece ofà functionality before functionality itself is implemented.à Refactoring: All developers are expected to re-factor theà code continuously as soon as possible code improvementsà are found. This keeps the code simple and maintainable.à Pair Programming: Developers work in pairs, checkingà each otherââ¬â¢s work and providing support to do a good job.à Collective Ownership: The pairs of developers work onà all areas of the system, so that no islands of expertiseà develop and all the developers own all the code. Anyoneà can change anything. Continuous Integration: As soon as work on a task isà complete, it is integrated into the whole system. After anyà such integration, all the unit tests in the system must pass. Sustainable pace: Large amounts of over-time are notà considered acceptable as the net effect is often to reduceà code quality and medium term productivity.à On-site Customer: A representative of the end-user of theà system (the Customer) should be available full time for theà use of the XP team. In an extreme programming process,à the customer is a member of the development team and isà responsible for bringing system requirements to the teamà for implementation. ï⠷ 1. 2. 3. 4. 5.

There are many existing models for developing systems for different sizes of projects and requirements. 2. These models were established between 1970 and 1999. 3. Waterfall model and spiral model are used commonly in developing systems. 4.

Asignment Performance Management Essay
Weiss and Hartle (1997) ââ¬Å"A process for establishing a shared understanding about what is to be achieved and how it is to be achieved, and an approach to managing people that increases the probability of achieving successâ⬠* In my experience performance management means different things the different people. In the company I currently work for performance management is thought of in the negative as being a process by which managers are able to take employees to task over bad performance and ultimately get rid of them. This may seem archaic and it is the most negative example I have come across in my work life so far, however, even in more forward thinking companiesââ¬â¢ employees are often skeptical and suspicious of the performance management process. Conversely I have been fortunate to see performance management at its best. For me performance management is all about taking the core goals of the organisation and ensuring that departmental, team and individuals tasks and behaviors link to and support these goals. In this way employees understand what is expected of them, why the work is important and how it links into the overall performance of the organisation. They are engaged and feel confident in their work knowing that they are contributing to the success of the company. Performance management assists oganisations in motivating and empowering their employees by setting clear goals and rewarding them not only for what they achieve but also the way in which they achieve. In doing this organisations can focus on what is really important to the success of the business. They can recruit and retain the best employees, and motivate and develop by training and challenging the workforce. Performance management allows succession planning so that job roles can be filled with skilled, motivated, experienced employees. Components of Performance Management Performance management is a cyclical process involving a number different components. Goal setting is a key component of the Performance Management process. The organisationââ¬â¢s overall goals should start the chain and depending of the size and structure of the organization these goals. The process should start with the organisational goals which are designed to ensure the performance of the organisation leads to successful business. These goals cascade down to business areas, departments, teams and individuals. For individual employees their job description and the teamââ¬â¢sà goals will form the basis of their individual goals. It is important that they understand how their own goals link into those of the organisation, why the work they are doing is important and how it contributes to the overall success of the organisation. There must be agreement on individual goals if they are to be embraced by the individual and they must be SMART if they are to be effective. Specific Measureable Achievable Results Orientated (Relevant) Time bound It is important that individuals are clear on what is expected of them, that they feel the goals can be achieved and that they that they are challenging and interesting. Key to the achievement of goals is regular communication. Communication may be formal or informal but can include updates from the individuals, feedback from colleagues, managers and clients, one to ones or team meetings. This communication is invaluable in employees on track to achieving their goals and making changes when necessary. Performance appraisals are another important component of performance management. These events are often undertaken annually and provide a formal appraisal of the individualââ¬â¢s competence in their role. Individuals and their managers have the opportunity to discuss, provide feedback and evidence of the individualââ¬â¢s achievements (against goals) and, in some organisations, the way in which those achievements were met (behaviours). Some companies also undertake half yearly reviews or appraisals with the view to making sure that that performance stays on track between annual appraisals. This is also an opportunity to review existing goals and set new ones. Performance improvement or development planning is another part of performance management. Areas for improvement or development may be identified at any time during the performance management process but typically come out of appraisal discussions. As with goals it is important that there is agreement on development plans and that activities to develop individuals are varied and effective. If employees are going to achieve their goals and develop their skills, knowledge and delivery within their role they must have access to the appropriate training and coaching. Whether employees requireà development because they do not meet their current performance requirements or in order to progress to the next level, training and coaching are also key elements within a comprehensive performance management process. Motivation and performance Management This relationship between motivation and performance management can be complex and individual to each employee. There are numerous motivational theories all of which have elements of authenticity to them. I have looked at two motivational theories, McGregor and Vroom. Douglas McGregorââ¬â¢s theory ââ¬Ëdetails two contrasting models of workforce motivationââ¬â¢ ** Theory X suggests that the average person is basically lazy and donââ¬â¢t like work. They prefer to be told what to do and donââ¬â¢t want responsibility. As such there needs to be tight control of the individual and threats of loss or punishment are the best ways to motivate them. Theory Y is the opposite, assuming that most people enjoy work, that they are happy to take responsibility under the right circumstances and that they can be self-motivated to do a good job. This motivation can be enhanced when managers are able to appreciate the employee and develop their trust. Victor Harold Vroomââ¬â¢s theory, to me, has links to the ââ¬ËY Theoryââ¬â¢, the theory suggests that factors such as personality, skills, knowledge, experience and abilities drive an individualââ¬â¢s performance. It proposes that employees are motivated by what they expect to receive in return for their effort and what that expected reward means to the employee. This is referred to as ââ¬ËExpectancy theoryââ¬â¢ and links together in the following way: Expectancy: Does the individual feel the effort they put in will lead to high performance. What is their levels of confidence in what they are capable of doing? Do they have the appropriate resources, knowledge and training to carry out their role? Instrumentality: If the individual achieves a high level of performance is there reward for their efforts and can they be sure they will receive it. Employees must be able to trust that they will. Valence: Is the reward offered/expected one that the individual values. For the reward to motivate it must have importance for the individual, be it financial, recognition, promotion and so on. For me the key to Vroomââ¬â¢s theory and its success in motivating employees is that every individual is different, each has their own needs, wants, expectations and values based on the individuals frame of reference. Management must know and respect the individual and what they want. Reward within Performance management: I have already discussed reward in relation to motivation and how the reward on offer may need to bespoke to the individual in order to be effective. There is, however, a far wider aspect to reward with a performance management process. Reward to attract and to motivate Pay is usually the first thought when talking about reward in employment. It is important that a realistic but attractive salary is offered initially when recruiting new employees. Pay continues to be important for most individuals throughout their employment, however it is not the only way in way employees can be rewarded. Within my current organization pay is only increased annually, across the board, which has little to do with performance except for acknowledging that employees are rewarded for working for the company in line with cost of living rises. Currently there is no performance management process within my organization other than dealing with poor performance in a ââ¬Ëtheory Xââ¬â¢ style, employees are serviced with a notice of improvement linked to termination of their contact. Outside of the annual pay increase financial reward is only given if a good employee threatens to leave. Practice is known to all employees via the grapevine and acts to demotivates those who donââ¬â¢t wish to take this approach. I have, however, worked within another organization where annual increases were calculated on performance throughout the year based on a truly robust appraisal system. Engaged and motivated employees were encouraged to collect factual evidence of their achievements and to present and rate this evidence at their appraisal. Ratings were discussed and agreed and then, then to ensure fairness, underwent cross calibration at departmental level. Employees felt they were treated fairly and rewarded not just for their efforts over the year but for their ownership of managing their own performance. Another type of reward for performance, which is being rolled out currently by my employer, is to provide opportunity for high performingà individuals to their knowledge of the business through a shadowing scheme. This has raised employeeââ¬â¢s morale as they feel they will be able to perform more effectively and this could, in turn, lead to better opportunities and perhaps promotion. It has also encouraged other individuals to improve their performance in order to be able participate in the scheme. As I have discussed an employeeââ¬â¢ perception of the value of reward will vary from one to another. values The need to provide a variety of rewards in line with employeeââ¬â¢s expectations and personal preference is supported in the concept of Total Reward schemes.

Definition and Examples of a Lingua Franca
Definition and Examples of a Lingua Franca A lingua franca (pronounced LING-wa FRAN-ka) is a language or mixture of languages used as a medium of communication by people whose native languages are different. It is from the Italian, language Frankish and also known as a trade language, contact language, international language, and global language. The term English as a lingua franca (ELF) refers to the teaching, learning, and use of the English language as a common means of communication for speakers of different native languages. Examples and Observations Where a language is widely used over a relatively large geographical area as a language of wider communication, it is known as a lingua francaa common language but one which is native only to some of its speakers. The term lingua franca itself is an extension of the use of the name of the original Lingua Franca, a Medieval trading pidgin used in the Mediterranean region. (M. Sebba, Contact Languages: Pidgins and Creoles. Palgrave, 1997) English as a Lingua Franca (ELF) The status of English is such that it has been adopted as the worlds lingua franca for communication in Olympic sport, international trade, and air-traffic control. Unlike any other language, past or present, English has spread to all five continents and has become a truly global language. (G. Nelson and B. Aarts, Investigating English Around the World, The Workings of Language, ed. by R. S. Wheeler. Greenwood, 1999)Even though everybody around the world speaks Englishsort ofin their dealings with American media and business, politics, and culture, the English that is spoken is a lingua franca, a Bodysnatched English to be carefully scrutinized as to its meanings when it is used by a foreign culture. (Karin Dovring, English as Lingua Franca: Double Talk in Global Persuasion. Praeger, 1997)But what do we mean by the term English as a lingua franca? The term lingua franca is usually taken to mean any lingual medium of communication between people of different mother tongues, for whom i t is a second language (Samarin, 1987, p. 371). In this definition, then, a lingua franca has no native speakers, and this notion is carried over into definitions of English as a lingua franca, such as in the following example: [ELF] is a contact language between persons who share neither a common native tongue nor a common (national) culture, and for whom English is the chosen foreign language of communication (Firth, 1996, p. 240).Clearly, the role of English as the chosen foreign language of communication in Europe is an extremely important one, and one that is on the increase. . . . It is important to note that this means that both in Europe as well as in the world as a whole, English is now a language that is mainly used by bi- and multilinguals, and that its (often monolingual) native speakers are a minority. (Barbara Seidlhofer, Common Property: English as a Lingua Franca in Europe. International Handbook of English Language Teaching, ed. by Jim Cummins and Chris Davison. Spr inger, 2007) Globish as a Lingua Franca I want to draw a distinction between a language which is spread through nurture, a mother tongue, and a language that is spread through recruitment, which is a lingua franca. A lingua franca is a language that you consciously learn because you need to, because you want to. A mother tongue is a language that you learn because you cant help it. The reason English is spreading around the world at the moment is because of its utility as a lingua franca. Globisha simplified version of English thats used around the worldwill be there as long as it is needed, but since its not being picked up as a mother tongue, its not typically being spoken by people to their children. It is not getting effectively to first base, the most crucial first base for long-term survival of a language. (Nicholas Ostler quoted by Robert McCrum in My Bright Idea: English Is On the Up but One Day Will Die Out. The Observer, October 31, 2010) Cyberspace English Because the cyberspace community, at least at the moment, is overwhelmingly English speaking, it is appropriate to say that English is its unofficial language. . . .The colonial past, imperialistic stealth, and the emergence of other language blocs in cyberspace as it grows will minimize in due time the preeminence of English as the de facto language of cyberspace. . . .[Jukka] Korpela sees another alternative to cyberspace English and a constructed language. He predicts the development of better language machine translation algorithms. Such algorithms will result in efficient and sufficient quality language translators, and there will be no need for a lingua franca. (J. M. Kizza, Ethical and Social Issues in the Information Age. Springer, 2007)

Free Essays on Prohibition
Causes and Effects Of the Prohibition Since at least the turn of the century, reformers had been denouncing alcohol as a danger to society as well as to the human body. The true feeling behind this thought was that the use of alcohol was due to the influence of the city. The first American colonists started out with the belief that city life was wicked and evil, whereas country and village life were good (Sinclair 10). Later, during the war, the idea of prohibition was a way of keeping the country patriotic, and thus strong. A common phrase was ââ¬Å"A drunk worker is not a productive workerâ⬠(McDonnel 394). Throughout history, there were many reasons to push a Prohibition amendment; however, though many of the causes for Prohibition were honorable, most of the effects did more harm for America than good. The first section of the Eighteenth Amendment of the U.S. Constitution states, ââ¬Å"After one year from the ratification of this article, the manufacture, sale, or transportation of intoxicating liquors within, the importation thereof into, or the exportation thereof from the United States and all territory subject to the jurisdiction thereof for beverage purposes is hereby prohibited.â⬠What this meant was, it was illegal to make, transport, or sell alcoholic beverages in the United States. Lasting almost fourteen years, the Eighteenth Amendment was repealed in December of 1933, when the Twenty-First Amendment was ratified under Franklin D. Roosevelt. In this short time, America underwent a great transformation due to the new law. There were many causes for the Prohibition movement. One main cause was religious revivalism. Prohibition was a result of the Protestant communities action to assert its dominant position in the nationââ¬â¢s culture. They believed that once this was achieved, the whole nation would be under the sway of Protestant moral values. Social reform was another reason Prohibition was supported. ââ¬Å"Prohibition was an at... Free Essays on Prohibition Free Essays on Prohibition The ââ¬Ënoble experimentââ¬â¢ of Prohibition left a lasting impact on the United States of America despite its relatively short existence. The 18th Amendment to the Constitution was ratified in January of 1919 and prohibited the sale, manufacture and transportation of liquor in the United States one year after ratification. The Volstead Act of 1920 enforced the 18th Amendment of the Constitution and began the era of prohibition that concluded in 1933. The issue of alcohol consumption and distribution was a long-standing one in the United States. However, the introduction of Prohibition coupled with the social problems of the time lead to a dark spot in American history. A combination of social problems and Prohibition lead to the rise of organized crime, and organized crimes most feared gangster, Al Capone. This paper will discuss the impact of Prohibition on the United States and the emergence of organized crime, and in particular, Al Capone. Prohibition was introduced in the United States for a vast number of reasons. Prohibition was undertaken to reduce crime and corruption, solve social problems, reduce the tax burden created by prisoners and poorhouses, and to improve the health and hygiene in America. Traynor also indicates the entry of America into World War I in 1917 also increased the pressure on the government to introduce a federal ban on alcohol. The problems faced by the nation that lead to the introduction of Prohibition seem far to complex to be solved by a ban on alcohol. However, there was a definite excitement that surrounded Prohibition and the anticipated results of its introduction. This excitement is no more evident that in Reverend Billy Sundayââ¬â¢s speech in which he predicted that ââ¬Ëthe reign of tears is over. The slums will soon be a memory. We will turn our prisons into factories and our jails into storehouses and corncribs. Men will walk upright now, women will smile and children will l augh. Hell will be for... Free Essays on Prohibition This essay deals with the Prohibition that was in effect in the United States between 1920 and 1933. The essay focuses on the reasons that the Eighteenth Amendment, which put Prohibition into effect, was eventually repealed. The thesis is that though the `Noble Experiment' had some good effects, the drawbacks, real and perceived eventually convinced Americans that the country was better off without Prohibition and enabled them to rapidly move to repeal the Eighteenth Amendment. The causes of repeal that are focused on in this essay are the fact that Prohibition was unenforceable; the fact that the public began to lose confidence in the success of Prohibition; and the fact that anti-prohibitionists capitalized on this lack of confidence to eventually spur the public toward repeal. The conclusion reached at the end is a rather philosophical one. When all the evidence has been reviewed concerning the problems with Prohibition, the benefits of the same, and the way public opinion changed, it becomes clear that in a democratic society such as the one in which this prohibition was attempted, the will of the people is paramount. If the people of a democratic nation decide to do something to change their situation, they will. This is first seen in the enactment of the Eighteenth Amendment. Later, when public sentiment changed to the reverse of what it had been, Americans were able to quickly reverse what they had done, even though it was the sacrosanct act of changing the Constitution. Table of Contents Introduction Unenforceability Changing Public Opinion Uncertainty Repeal Conclusion Bibliography Introduction On January 17, 1920, at 12:01 AM, the Volstead Act went into effect all over the United States.

Free Essays on Prohibition Prohibition and the 1920ââ¬â¢s The 1920ââ¬â¢s are often described as the decade of contrast and conflicts. It was a decade that some would say was the worst decade in American history. The 18th amendment to the constitution was passed by congress in 1917. It was ratified by three fourths of the states by 1919. This amendment prohibited the manufacture and sale of alcoholic beverages within the boundaries of the United States of America. Prohibition was officially underway. The Volsted Act of 1919 defined an alcoholic beverage clearly as any beverage with an alcoholic content of greater than .5 %. This made it illegal to sell and manufacture all liquor and beer. (Shultz 1) Prohibition was a phenomenon during the 20ââ¬â¢s. It was not however the first campaign against alcohol, but it was by far the most successful. There had been numerous anti-alcohol campaigns during the colonial period. None of which were as successful as the national prohibition laws in the 20ââ¬â¢s. For example in 1851 the Maine Law prohibited the manufacture and sale of alcohol in the state of Maine. By 1855 thirteen other states had adopted similar laws. During the Civil War alcoholic beverages were not allowed in the union army as a way to ration grain. Leaders of the social movements tried to justify their views against alcohol with scientific evidence. Temperance advocates founded the Scientific Temperance Journal after the Civil War. Childrenââ¬â¢s textbooks depicted human organs degenerating from and over abundance of alcoholic beverages being consumed. In the 1870ââ¬â¢s the Womanââ¬â¢s Christian Temperance Union (WCTU) promoted the use of public education for the cause of temperance. They were very successful with that. By 1902 every state and territory except for Arizona had a law requiring temperance instruction in public schools. They argued that immigrants were inferior to the Americans because they allow their children to drink alcohol at...

Introduction: I. Imagine the reaction of people across the United States if President Bush were to come on television one day and tell the American people that there will be no more alcohol distributed, sold, or consumed in the U.S anymore. This was a reality on January 19, 1920 when the 18th amendment was passed into effect. II.

Argument Paper Fast Food
Zinczenko is saying that common sense would say it is personal responsibility to be an active eater and know what you are putting in your mouth. In discussions of fast-food obesity, one controversial issue has been the lack of the nutritional facts. On the one hand people should do research before they eat instead of blaming fast-food places. On the other hand the nutritional facts should be placed on the food itself. In my opinion, personal responsibility should be taken for what you eat because fast-food places are not forcing you to eat their food. For instance common sense says something that is dunked in grease and cooked in five minutes cannot be good for you. Becoming obese from fast-food is the result of no self-control. Grease in itself contains many calories and causes many problems with blood pressure, cholesterol and type two diabetes. Zinczenko states, ââ¬Å"Today According to the National Institutes of Health, type 2 diabetes accounts for at least 30 percent of all new childhood cases of diabetes on this countryâ⬠(Zinczenko 154). Type 2 diabetes is obesity related and a serious disease. Poulin 2 Common sense tells you eating two meals a day, in a fast-food restaurant, will cause you to gain weight. This unhealthy weight gain tells people that there is a problem to the way they are eating and it is not the washer shrinking their jeans. Instead of walking into McDonalds kids can walk into Subway and try a sandwich that is healthier and cost about the same as the huge meals they can get at McDonalds. There are healthier alternatives that re just as fast and taste as good as burger joints. Although I grant that many people might say there is no way of knowing how many calories are in fast-food meal has because of the lack of nutritional labels, labels are readily available on fast-food websites. The labels would not change the fact that it is personal responsibility to know that something that has been smothered in grease has no nutritional value. On the one hand, I agree with people that labels should be put on fast-food explaining what is in the food. But on the other hand, I still insist that people should do the research if labels are the main concern of nutritional values. Just because people have labels explaining the fat content does not mean they will stop eating the food. This is where personal responsibility needs to come into play. When people find out what really is in the food and the content of fat people need to be active and make the right decision to not add fast-food into their daily diets. Self-control is a huge factor here and people need to take charge, putting themselves in charge of a healthy lifestyle. In the end it is only the consumer who can control what they consume not the companies and blame cannot be put on that one party. Proponents of fast-food restaurants causing obesity are right to argue that the food causes you to gain weight when you eat it regularly, it is cheap, it is easily accessible, and it is catered to children. But they exaggerate when they claim that fast-food is the number one reason for child obesity in the United States. Poulin 3 You can argue that children who sit in front of video games and computers all day long are a huge contributing factor to the obesity rate. Their lack of activity can cause pounds to pile on and that has nothing to do with McDonalds Fast-food. For instance fast-food has always made me feel sick to my stomach. My common sense would tell me that as good as it does taste my body does not like fast-food. When I was younger I gained a lot of weight because I would eat at McDonalds every chance I got. I was unaware that I could be making better choices and choose not to eat it. Kids today are uneducated on how to make healthier choices and live healthier lives with the influences of fast-food. Zinczenko states, ââ¬Å"But most of the teenagers who live, as I once did, on a fast-food diet wonââ¬â¢t turn their lives around: Theyââ¬â¢ve crossed under the golden arches to a likely fate of lifetime obesityâ⬠(Zinczenko 154). If the country believes that fast-food is the cause of childhood obesity then why do we still continue to eat it? People need to realize labels are not put on the food because if people really knew what was in the food they would not continue to eat it. Again that is where common sense should tell you that you should not eat fast-food. Although at a first glance People, including young and old, might say that fast-food is the cause of being obese. But on a closer inspection it is really the individuals fault. For example people are so quick to blame fast-food restaurants for making them obese that they jump right to suing the corporation, but are they actually doing something about the obesity. Zinczenko mentions in his article how one meal can contain ââ¬Å"up around 1,040 calories which is half of the governmentââ¬â¢s recommended daily calorie intake. And that doesnââ¬â¢t take into account the 450-calorie super-size Cokeâ⬠(Zinczenko 155). The calorie intake should tell anyone that eating this way and especially eating this way twice a day is extremely unhealthy and fattening. People need Poulin 4 to speak up and demand labels. Zinczenko says, ââ¬Å"They would do well to protect themselves, and their customers, by providing the nutrition information people need to make informed choices about their products. Without such warnings, weââ¬â¢ll see more sick, obese children and angrier, litigious parentsâ⬠(Zinczenko 155). Parents need to be more active in their childrenââ¬â¢s lives and teach them about healthy life styles that way in the future generations can be much healthier. In conclusion people need to take personal responsibility for their own weight and stop forcing the blame on fast-food corporations. Common sense should tell you that greasy food is not good for you and that it has no nutritional value. Many people can say that labels are the cause of obesity because they are uniformed about what they are eating. Labels are readily available at any fast-food chain and on their websites. People need to speak up and come up with a solution to this issue rather than be part of the problem. Common sense also says that if it is cooked in grease it is a good chance it is covered in fat. People are responsible for their own lives and they need to stop blaming others for their short comings. Ultimately what is at stake here is a healthier generation.
