Relationship Between Human Beings and Nature Essay

Now is the time for human beings and nature to collaborate. Normally, most people would say, â€Å"human beings always destroy nature.† It is true. However, only a few people know the truth of why human beings destroy nature. It is a huge mistake to think of nature individually. First of all, the main reason people destroy nature is to use trees as materials for paper. As everybody knows, cutting trees has been becoming a reason for global warming. In the past fifty years, the number of people increased more than ten times. Of course, ten times more paper is consumed. The number of the trees in the world has been decreasing rapidly and the environment of the world is getting worse. On the contrary, there was some good news for protected nature. For example because of advancements in the economy, distribution of electric books helped to decrease the consumption of paper. Also, people think of nature more than before. Even now, the numbers of people in the world are increasing, so to have a good relationship between human beings and nature is not easy, it probably the situation is getting worse. We have to keep changing something. When I was living in Canada, I heard the Canadians have pride in protecting the earth. For example, Canada has a lot of natural resources, but they never sell these. They think selling oil leads to the destruction of nature. They also have strict rules for themselves. It is a big violation if they hurt nature or animals. I often think about the world. Everybody knows how to collaborate with nature and how the world would change if we keep destroys. Individual power is really small, but nothing is changed if we do not change. So, now is the time for human beings and nature to collaborate.

Highway Administrator Paper

The administrator of the highway department was given a task to find a way to fill more potholes. This program to fill more potholes would decrease the number of complaints in the city and the number of damages to the residents' cars. To do this, the Highway Administrator implemented a goal-setting program, in hopes this would encourage the workers to fill more potholes. This program sets a standard for each crew to fill a certain amount of potholes per day, no matter the location of where the crew was working.The results will then be posted for all of the crews to observe and compare. As an incentive to fill the most potholes possible, the crew who filled the greatest amount of potholes each week was given a reward. I personally believe excellent results will be achieved since the Highway Administrator's plan follows the design of the goal setting theory. â€Å"Goal setting theory was based on the premise that much human action is purposeful, in that it is directed by conscious goa ls. † (Neil, 1994) A more updated definition of the Goal Setting Theory states that goals are the remarry drivers of the intensity and persistence of effort.This program is going to be successful since the goals to be met are specific, accompanied by feedback, and difficult, but accepted by the workers. These aspects of the program will increase the overall performance of the workers, meaning more potholes will be filled in the approved manner, therefore, decreasing the number of complaints in the city and damages to the residents' cars. Since the duties assigned to the workers are meant to help the community, it is safe to say that their Job performance is meaningful.The errors have a clear, spelled out Job description and a list of tasks they need to complete, in the order they need to complete them. With their specific Job description and the workers helping out the community, overall Job satisfaction will rise, increasing Job productivity. â€Å"Meaningful work and Job sa tisfaction are linked,† (Weir, 2013) and typically lead to overall life satisfaction. Goals set by the highway administrator's program were specific. The standard set by the highway administrator were that each crew was to fill 20% more potholes than they usually fill on a daily basis.This aspect of the goal is extremely efficient and specific which gives the workers a clear idea of what they need to do at work. If the goal were to simply â€Å"fill more potholes than you normally fill† than each crew could fill one more pothole than they normally do and still meet the goal, but this would probably not complete as much work done as fast as it needs to completed. This goal is also a clear standard because of the different working conditions each crew operates in. Asking each crew to fill five more potholes than normal might prove to be easy for one crew and extremely difficult for another, depending on the conditions.Each crew was also given a step-by-step sheet on how t o properly fill each pothole. This will create a filled pothole that will last longer, therefore, making less work for the future. The feedback that accompanies each goal comes at the end of each week. Feedback is objective information about performance. Motivational feedback serves as a reward and the highway administrator clearly understands that since he is using rewards to drive his employees' productivity. (Hogue, 2004) Each week, the highway administrator will post performance data on a board for all of the other crews to view.Since there are only rewards and no harsh consequences, this creates friendly competition for each crew. The crew who has the most potholes filled at the end of each week wins tickets to a sports game in their locality. Since there is an incentive involved with the weekly performance, the crews will work much harder in order to come first and win the reward. This will drive up the work performance significantly since the reward is something people know t hey will enjoy. Finally, the goals are official, yet accepted by the workers. It may not be easy at first to fill 20% more potholes than average.Once the crews realize the goals are difficult, yet not impossible, the intensity and persistence of the workers will maximize in order to be the best and finish the work as quickly and efficiently as possible. Each crew will work their hardest to fill many potholes as possible. The incentives come into play once again when it comes to the goal being difficult since each crew knows if they work harder, they will achieve more potholes than the other crews. It is also beneficial to he program that performance statistics aren't posted until the end of the week.If they were to post performance statistics every day, crews with lower performance may feel discouraged if they are not filling the most potholes, leading them to not work as hard as they may feel they don't have a chance. The highway administrator's goal setting program is meant to rai se productivity and I predict that is exactly what will happen. Since the goal setting program is based off of the goal setting theory, it needs to follow three important aspects to be successful. When the goals are specific, accompanied by feedback, and difficult, but accepted by employees, they increase the performance of the workers.These aspects serve as the primary drivers of the intensity and persistence of effort. â€Å"In order for an organization to be successful they must continuously ensure the satisfaction of their employees. † (Yip, Goldman, Martin, 2009) Taking the goal setting theory into consideration, the ultimate goal is for the goal setting program to be successful. When workers are satisfied with their Job and the work they've done, along with possible rewards they may have earned, they will intuition to work harder. This is mainly since work itself has a strong correlation with job satisfaction.If someone is not satisfied with the work they do, they may n ot want to work as hard or be as productive. Employees that like their work find it easy to work harder and strive for their best. They do this by setting personal goals for themselves, relating to work, and achieving them. Each crew may come up with team and individual strategies in order to employ every effort to fill the most potholes. This program will raise the workers' productivity by raising the workers' satisfaction. If I were the highway administrator, I would implement the same program with minor tweaks.Ultimately, I feel that this program will drive workers to increase productivity and fill more potholes. With this result and more potholes filled, complaints from the citizens and damages to their cars' will decrease immensely. This would improve the overall moral of the city if more potholes were filled. The reward aspect of this program is one of the most important parts. â€Å"A good reward system should foster personal growth and development and keep talented people f rom leaving† (Grittier, 1998). This program does Just that, which is why I agree with it and how it will affect the workflow.When individuals set goals for themselves as well as try to receive rewards that may be awarded to them, they grow as a person and do not want to leave due to Job satisfaction and potential rewards. This leads to affective commitment by the workers. Workers will stay with the organization because they want to, not because they feel obligated or need to due to their financial situation. The only aspect I would change about this program is the percentage of potholes that need to be filled. I would survey each crews work area and give them team goals to meet.Anything above that would be compared to the other teams and the crew who was most effective would receive the reward. Overall, the highway administrator's goal setting program will work effectively and serve it's purpose of filling more potholes to construct a better community environment.

Journal Assignment Example | Topics and Well Written Essays - 250 words

Journal - Assignment Example Without a doubt, Poe does an excellent job of portraying the narrator’s behavior. The narrator is unable to explain his behavior clearly because his action of frightening the old man and then killing him was too spontaneous. As mentioned above, he is so befuddled and is driven mad by the guilty that he just could not beg to confess. One cannot diminish the fact that Poe provides a comprehensive understand of paranoia and mental corrosion of the narrator. In order to enhance the suspense, Poe deliberately adds key details of memories that the murderer confesses to such as the old man’s eyes and his heartbeat. In this particular instance, the â€Å"Tell-Tale Heart† depicts the psychological contradictions that one man faces as he tries to justify his brutal murder of an innocent old man. The justifications almost seemed that the man killed his victim due to self-defense when clearly that was not the case. Poe tries to depict the act of a criminal’s mind and his absurd obsession with the old man. Poe excels to depict this story in such a way that makes the narrator seem normal but insane at the same. Clearly, the narrator is confused with mixed emotions as he both loves and hates the old man. The true sense of love is shown as observes the man but then kills him due to hate.

3Th article that pertains to my reserach proposal - Assignment Example 100). The use of humor in this context provides a way to bring student interest to lessons and to motivate students. All students began by filling out a questionnaire about their background and they were given a standardized listening test (TOEFL Test, version 2009) to determine a baseline for their â€Å"listening proficiency level† (Rafiee, Kassaian and Dastjerdi, 2010, p. 102). Once students received instruction through the use of humorous songs, they were given the TOEFL listening test a second time. Participants had not previously participated in listening tests. Students were told that they would listen to a passage for several minutes and then they would be instructed to immediately do coursework. Teachers did not ask questions after the listening task in order to make sure that they were relaxed while listening. Students listened to 17, 90 minute sessions. After the first task, students were asked to listen to the passages again and repeat the task in order to have a pre- and post-test sample. After a three week interval, students were asked to take the TOEFL test again to measure t heir immediate ability to recall the information. There were 30 female participants in this study and they were all studying English at the Iranian Institutes of English language. The age group of participants was between 15 and 25. The participants were given a number between one and 30 and they were randomly chosen for two groups. The first group was comprised of those students who had odd numbers and these were seen as the control group. The second group was comprised of those students who had even numbers were used as the experimental group. The researchers found that students in the experimental group were able to retain more information than those in the control group. The researchers pointed out that humorous songs did have a â€Å"moderately large effect† (Rafiee, Kassaian and

Cultural Studies abstract Essay Example | Topics and Well Written Essays - 500 words

Cultural Studies abstract - Essay Example Issues related to the original shape and authenticity of the tales of Kitaro in the graveyard are examined by comparing various forms of the story in Kami-Shibai and the variations generated during the transition from Kami-Shibai to rental Manga. These are based on researches on street Kami-Shibai and rental Manga. Creation in Kami-Shibai, which has no prior story documented, depends mainly on sequencing of images with speech language and reaction from the audience. Therefore, as for street Kami-Shibai, the accumulation of various versions as one story must be put into consideration. Orality, a main feature of Kami-Shibai, is subject to fundamental and crucial transformations due to changes in representation techniques and authorship during its transition to Manga. The consciousness and analysis of Manga readers are centered primarily on words or text. The recipients of Manga and animation tend to be categorized as fanatics and this makes the issue of popular culture use and ownership even more complex. This paper also tackles the authorship and ownership of popular culture in the age of technological media. The relationship between cultural likeness and transformation of media technology is discussed while the arguments of studies on â€Å"transmission† [densho] in Japanese folklore studies, anthropological resemblance, power in cultural studies, and creative similarities are examined in discussing actual copyright issues of Manga, digital copyright, and problems encountered in its creation on the

Code of Professional Ethics & Conduct (4) Essay

Code of Professional Ethics & Conduct (4) - Essay Example Therefore, it institutes ethical requirements for the CPAs who are expected to comply with all parts of the code. However, a breach in one or several of the code requirements leads to disciplinary action administered by the relevant bodies (Crawford & Loyd, 2008). Rule 102: Integrity and Objectivity Paul T. Fink of the Eagan, Minnesota was suspected of a breach in Rule 102, the integrity, and objectivity code. The case entailed the suspicion of a breach in conduct with respect to performance of professional services as controller and chief financial officer of a publicly held entity. According to the code, a CPA â€Å"knowing misrepresentations in the preparations of financial statements or records, or permits or directs another to sign, a document holding significantly false and deceptive information† (AICPA, 2012). Mr. Fink was guilty of participating in backdating several shipping documents meant to correct on expiring letters of credit whose terms had been defaulted. There were other discrepancies detected in the bill of lading in the year 1996 that did not tally with the inland bill of lading signed the same year. He also signed forms 10-QSB in the second and third quarter of 1996 in full knowledge of the inability of the firm regarding the fulfillment of the contract terms of sale. After the completion of the investigations, Mr. Paul Fink was also guilty of violating Rule 102 on integrity and objectivity. Following the scrutiny of the evidence by the Joint Trial Board, Mr. Paul membership with AICPA was terminated and his practice certificates revoked. The disciplinary action taken on Mr. Paul was justified. This is because the CPAs perform a fundamental role in society. All the members of AICPA should be consistent with the requirements of the body (AICPA, 2012). Failure to do so, Mr. Paul failed to take the responsibility of representing his professional ethics as required thus breaching the stakeholders trust towards the body and the business. T he AICPA can prevent this type of breach in the code of conduct by ensuring that the CPAs frequently observe their needed commitment to the code. The penalties administered should also be strict in order to curb further breach in the code. Rule 201: Professional Competence The code of professional competence requires a CPA to safeguard a clients’ data. Rule 201 states that â€Å"a member remains responsible for ensuring the accuracy and completeness of the services provided by third-party provider† (AICPA, 2012). Therefore, a CPA should provide professional services performed with professional competence and care. David Beck of Lexington allegedly violated the code in the year 2010 where he was accused of lack of professional services in relation with the audit of a business entity. In his practice, he failed to comply with the standards by failing to plan and conduct the engagement, failing to participate in the planning meetings and organizing the audit staffing (Rit tenberg, Johnstone & Gramling, 2010). In addition, he failed to record the necessary documents and details of his audit procedures. After consideration of all the presented evidence, the Joint Trial Board found Mr. David Beck guilty of a breach in rule 201, Professional Competence. Moreover, he violated an AICPA Bylaw for failing to cooperate with Ethics Charging Authority by providing a substantive response to the investigation. As

How to Write an Article Review Essay Example for Free

How to Write an Article Review Essay Writing an article review, which is also sometimes referred to as an article critique, is a special type of writing that involves reading an article and then providing the reader with your personal take on its content. In general, article review essays should start with a heading that includes a citation of the sources that are being reviewed. The first paragraph, which is the introduction to the article review, should provide a summary of the article highlights. This summary should not provide every last detail about the article being reviewed. Rather, it should only discuss the most important details. If you find yourself carrying on or needing more than one paragraph to write your summary, you need to revisit the paragraph and find ways to trim down the length of your summary. Following the brief summary of your article, you will then need to explain why the article is significant. Questions you should ask yourself when writing these paragraphs include: Does the article fill a void within the literature that already exists on the topic? Does the article contain any information that would be considered â€Å"breakthrough† information? Will the information contained within this article cause other people in the field to change their ideas about the subject matter or does it simply revisit information that is already known in the field? In your final paragraphs, you will need to present your personal evaluation of the article. Some questions you should ask yourself in order to come up with your personal evaluation include whether or not the article is well written and clear. You should also consider whether or not any information was missing and if more research is needed on the topic. If you are writing the article review for a class, try to connect the article to organizational and industrial experience and try to connect the content of the article to information that you have been studying in your course. As you write your article review, keep in mind that you are doing more than just a book report. Rather than focus on telling what the article was about, your article review should reflect your personal opinions on the article as well as how it affects you or the field in which it was written. After you have finished writing your article review, be sure to go back and re-read it. This way, you will be able to look at it with a fresh set of eyes and you may notice errors that you had not previously noticed. Outline of the Article Review Please include the following categories in your article review. Full Bibliographic Reference Introduction: Objectives, Article Domain, Audience, Journal and Conceptual/Emprical Classification Very Brief Summary Results Contributions Foundation Synthesis with other materials Analysis Additional Analysis General Critique) Further Critique of a Conceptual Article -or- Further Critique of an Empirical Article Issues (in your opinion). Questions Annotated Bibliography Citation Analysis Appendix 1. Full Bibliographic Reference State the full bibliographic reference for the article you are reviewing (authors, title, journal name, volume, issue, year, page numbers, etc. ) Important: this is not the bibliography listed at the end of the article, rather the citation of the article itself! 2. Introduction: Objectives, Article Domain, Audience, Journal and Conceptual/Emprical Classification Paragraph 1: State the objectives (goals or purpose) of the article. What is the articles domain (topic area)? Paragraph 2: State whether the article is conceptual or empirical, and why you believe it is conceptual or empirical. Empirical articles and conceptual articles have a similar objective: to substantiate an argument proposed by the author. While a conceptual article supports such an argument based on logical and persuasive reasoning, an empirical article offers empirical evidence to support the argument. Empirical articles offer substantial, detailed evidence which the authors analyze using statistical methods. Empirical articles must include hypotheses (or propositions), detailed research results, and (statistical) analyses of this empirical evidence. Empirical research includes experiments, surveys, questionnaires, field studies, etc, and to limited degree, case studies. Conceptual articles may refer to such empirical evidence, but do not provide the detailed analysis of that evidence. 3. Brief Summary For an article review, do not spend much space summarizing the article. Instead focus on analysis of the article. Thus, in this section, summarize the article only very briefly. Paragraph 1: what is the problem or opportunity being addressed Paragraph 2: which solution is proposed (the solution could be a new model or a theory that explains the problem) Paragraph 3: what evidence is put forth that this solution is appropriate (If this is an empirical article, be sure to briefly describe what kind of empirical study was done as part of the evidence) 4. Results Very briefly summarize the important points (observations, conclusions, findings) in the article. Please do not repeat lists of items in the articles just summarize the essence of these if you feel they are necessary to include. 5. Contributions. An article makes a contribution by adding to the knowledge of researchers in a research field. An article can make a contribution to the research field in many ways. Does it provide a new way to look at a problem? Does it bring together or synthesize several concepts (or frameworks, models, etc. ) together in an insightful way that has not been done before? Does it provide new solutions? Does it provide new results? Does it identify new issues? Does it provide a comprehensive survey or review of a domain? Does it provide new insights? Also, is it salient (relevant and current) to a particular scientific issue or managerial problem? Are the issues addressed introduced in a way that their relevance to practice is evident? Would answers to the questions raised in the article likely to be useful to researchers and managers? Note: Do not discuss the contributions of the technologies the article describes, but rather the contributions of the article itself! The articles contributions should be original. Describe each contribution clearly in a separate paragraph or bullet point. Discuss why the contribution is important. Alternatively, if you believe the article makes no contributions, explain why clearly. 6. Foundation. Good research often is built upon theories and frameworks that other researchers have developed. Sometimes articles will be substantially based upon this prior work, and refer back to it in some detail. (Not all research articles will do this. ) Which theoretical foundations does this article and research build on, if any? In what ways? Include references/citations of the foundation work. (You can determine this in part from the works the article cites. )Note, however, that most works cited are not core foundational work, but rather just support certain aspects of the article. Similarly, do not confuse a general discussion of related topics as foundational work. If the article does not build upon key pieces of prior research, then write in your review This article does not build upon any foundation research. (If you do not state this explicitly, you will not receive credit for this section. ) 7. Synthesis with Class Materials Synthesis means analyzing a particular topic by comparing and contrasting it with, and thinking about it from the viewpoint of, the class materials from across the semester. These materials include the articles, models, frameworks, guidelines and other concepts weve covered. (Of course, only certain materials will be relevant for any given article. )Note: You have to do this synthesis! You need to relate this article to other things we have studied, so by definition you will not find this analysis in the article itself! You also could analyze the approach the author took to the articles analysis and discussion. Discuss the articles approach and results in terms of one or more of the frameworks, etc. , from the text or readings, or any you find elsewhere. As part of this analysis, reference other articles youve read, when appropriate. Compare the approach, results and contribution with all articles about similar topics or with a similar approach. For all of these, do your synthesis comparison in as much depth as you can! 8. Analysis Note: Many people assume this category is the same as General Critique. It is not. General Critique is a different category from this, and follows below. What has changed since the article was written? How do its lessons, ideas and theories still apply? To what extent has its issues been resolved? Additional Analysis Optionally, try applying the articles models, frameworks and guidelines, etc. yourself. Do you find them useful? In addition, you may optionally add your own additional analysis in a separate subsection. (Do not repeat the authors analysis in the paper you could summarize this as part of the results section. ) 9. General Critique In this section you should state your opinions of how well (or poorly) the authors did their research and presented the research results in the article. Your critique can contain both positive and negative comments. Justify and explain in detail each of your critique points in a separate paragraph of at least 4-5 sentences. The following are suggestions only: Does it build upon the appropriate foundation (i. e. , upon appropriate prior research)? Did the authors choose the correct approach, and then execute it properly? How confident are you in the articles results, and why? Are its ideas really new, or do the authors simply repackage old ideas and perhaps give them a new name? Do the authors discuss everything they promise in the articles introduction and outline? What are the articles shortcomings (faults) and limitations (boundaries)? Did it discuss all of the important aspects and issues in its domain (topic area)? In what way should the article have made a contribution, but then did not? Do the authors make appropriate comparisons to similar events, cases or occurrences? How complete and thorough a job did the authors do? Do the authors include an adequate discussion, analysis and conclusions? Did they justify everything adequately? Did they provide enough background information for the intended audience to understand it? For you to understand it? Were there adequate and appropriate examples and illustrations? Ask yourself these questions when justifying your critique points: why/why not? how? what distinguishes the differences/different approaches, and in what ways? 9. 1. Further Critique of a Conceptual Article (only for conceptual articles) A critique of a conceptual article examines the logic of the arguments made by the authors. Both strengths and weaknesses should be identified in a critique. Explain and justify each of your critique points in at least 3-4 sentences. Give examples whenever possible. To the best of your abilities, discuss each of the following categories in a separate paragraph: 1. LOGICAL CONSISTENCY: Do any parts of the article or research contradict or invalidate other parts? If so, have the authors acknowledged and explained this adequately? 2. COHERENCE: Does the article make sense? Did the authors approach this article (and this research) sensibly? Does the article develop an argument that follows a coherent line of reasoning? Are the boundaries of the argument reasonably well defined? Does the argument anticipate most, if not all, rival arguments? Does the article flow in a logical sequence? Do later parts build logically upon earlier parts? 3. SUBSTANCE: Does the article provide an argument or a line of reasoning that offers insight into important issues, or does it merely summarize previous studies in a shallow way that does not reflect depth of analysis? Does the article provide ways (a model, framework, guidelines, etc. ) to guide future thinking about the issue(s) the author is addressing? 4. FOCUS: Is there a clear audience that the authors address? Was the article written at the appropriate level for this audience? 9. 2. Further Critique of an Empirical Article (only for empirical articles) A critique of an empirical article examines the strength of the empirical evidence supporting the authors argument. Both strengths and weaknesses should be identified in a critique. Explain and justify each of your critique points in at least 3-4 sentences. To the best of your abilities, discuss each of the following categories in a separate paragraph: 1. CLARITY: Is the articles purpose and argument clear? Do the researchers clearly develop a major research question, proposition, or hypothesis that is to be evaluated in the empirical study and discussed in this article? If the study is exploratory (preliminary), is sufficient justification for an exploratory strategy given? 2. THEORETICAL GROUNDING: Is the researchers argument grounded in more basic theory? Is it clear whether the structure of the empirical study (i. e., what they do) was derived from theory, or just made up? In theory-building articles, is the need for new theory adequately established? 3. DESIGN OF RESEARCH INVESTIGATION: Is it clear exactly how the empirical study was carried out? Is the design of the research approach (field study, experiments, questionnaires, etc. both contents and how they will be used) adequate to address the common threats to internal and external validity? Have appropriate controls been established, and is the selection of research sites justified? Are the hypotheses and experiments, etc., significant? 4. MEASUREMENT: Empirical studies can have quantitative measurements (i. e. , numeric results) and qualitative or subjective measurements. Are the measures used adequately described (i. e. , what is measured in the study and how)? Are data on the reliability and validity of these measures reported? Does the article feel anecdotal or solidly supported with evidence? For example, in case or field studies, are the results well documented? Is it clear who the subjects were, and with whom interviews were carried out? Were important results cross-checked, i. e., determined across a range of subjects or just gotten from one or two subjects? 5. ANALYSIS: Is the analysis of empirical data conducted properly? Do the data conform to the requirements of any statistical tests used? Are qualitative data adequately described and presented? 6. DISCUSSION AND CONCLUSIONS: In discussing the results of the empirical study, do the authors remain true to the actual findings of the study? Are the claims made in the conclusion of the article actually supported by the empirical data? If the study is exploratory, do the authors offer research questions or hypotheses for future research? 7. BIASES: Do the biases of the authors affect the design of the research or the interpretation of the results? Are the authors aware of potential biases and the affect on the study? 10. Issues (listed by the author) What open questions or issues has the author stated remain unresolved? Discuss each in a separate paragraph of 5-10 sentences. Each issues paragraph should take the following format: what is the issue? why do you believe this is an important issue? in what way is it unresolved suggestions for resolving it if you give your own suggestions (instead of or in addition to the authors, then precede each with I would propose If it has been resolved since the article was written, then state how it was resolved. 11. Issues (in your opinion) List several open questions or issues which remain unresolved in your opinion? For example, what possible future research questions could arise from this article? Discuss each in a separate paragraph of 5-10 sentences. Each issues paragraph should take the following format: what is the issue? why do you believe this is an important issue? in what way is it unresolved suggestions for resolving it 12. Questions List three insightful questions of your own, arising from this article. Do not ask definitions, but rather questions that really make one think. 13. Annotated Bibliography For every item you have cited in your report, you need a full reference and an annotation explaining it. List the full bibliographic references (authors, title, journal name, volume, issue, year, page numbers, etc. ) for anything you have cited in your review. IMPORTANT: This is NOT the bibliography listed at the end of the article. It is the bibliographic references for any readings you yourself referred to inside your review.

What automation does Essay Example for Free

What automation does Essay Office automation is one of the most important step towards the development of a better operations environment (Endrijjonas, 2005). Automation is considered a sure way to the development of a better operational environment and is often associated with increased productivity. Automating an office alone is not enough in ensuring this as the human aspect and contribution in automation is considerable. It is necessary for humans to intervene in any automated process as machines are created by man and are therefore bound to err. Moreover, the implementation of an automated office environment largely depends on the instruction streams that the system has been programmed with and is thus heavily dependent on the nature of the organizations operations. Automation is seen as a means to ease the work load. The office environment is one of the most tedious environment one can be in. The number of processes required for the functioning of an office make it difficult to implement a manual system. Therefore, an automated system does the same work in an environment that provide multiple functionality and at a speed that no ordinary man can ever achieve. Thus, the workload is managed more efficiently as the accuracy associated with the use of machines is higher than that of a manual system. Moreover, machines are seen as a means to the elimination of repetitive processes, and therefore the available human resource is used optimally. The overall result of the implementation of an automated system is efficiency in the operations process, which lead to optimal performance and thus increased performance which is seen in high throughput. One of the most misunderstood aspect of office automation is that the creation of a new system or tool is mandatory. This is a fallacy as there are instances where a wise selection of the available tools is all that is needed. Moreover, automation may imply the development and improvement of the existing system tools. Advantages Of Building There are several pros associated with building office automation software from scratch. The nature of the organization plays an important part in the determination of the advantage that the organization will accrue as a result of such a decision. Building is defined as coming up with a new system from scratch or from the system that is currently in place. Therefore, building is an initiative that will take place in the organization for a considerable time period and should therefore be monitored well within the organizational context. Economic One of the major consideration that an organization has to make in consideration of the development path in coming up with an automated Helpdesk support system is economic growth (Endrijjonas, 2005). The main aim of any business is making profits so as to engage in developmental and diversification agenda. The economic benefits accrued by the implementation of a system is thus a major consideration in deciding whether to choose or buy. When an organization builds a help desk support system, the organization from the first day of implementation becomes the owner of the system. Therefore, its asset base increases and so does the stability. This trend continues and any additional features added to the system will not only improve the efficiency of the system but also ensure that the organization grows. Therefore, the approach ensures that the organization grows at a level that is sustainable in consideration of its resource base. Furthermore, the need for additional funding, expertise and support from outside sources is eliminated or reduced by building. The needs of organizations may change, and they often do considerably. An important consideration in ensuring the growth of an organization is the effective address of their needs as at the time of occurrence (Grabbe, 2007). Industry and market trends are not the easiest aspect of business to predict as they are influenced by factors that are beyond the control of man. As a result the nature of an organizations need for automation is quite dynamic. A problem of this nature definitely requires a solution that befits, building an automated Helpdesk support system goes in line with dynamism. Building ensures that the system meets its objectives. Learning and development of technical staff is a consideration in development; the IT staff in developing the system get first hand knowledge and experience in developing and thus gain skills which will lead to better delivery by the automated system. Change is an aspect that is not easily accepted not only by humans but also by particles. According to Newton resisting change is normal for any particle, the psychological effect of change causes a general resistance (Kenyon, 2001). Therefore, organizations are often advised to implement changes in a gradual manner so as to ensure that all members of the organization are in line with the changes and thus uniform growth is experienced. Implementing an automated system is a change process and any organization should treat it one. Building an automation software goes in line with this and is thus appropriate is therefore appropriate. This is a very important consideration as the effect of a poorly managed change process on the economic stability of an organization is far much worse and often offsets the benefits and is a situation that any organization should go at any length to avoid. Cultural Organizational culture is cultivated for a number of years. Changing the culture as a means to development takes a number of years (Endrijjonas, 2005). Failure to incorporate the correlation of a strategy to corporate culture and the effect they have on each other is a source of failure of many project. Automation of office Helpdesk services is no exception and therefore all organizations must adopt a positive attitude towards the development of a culture friendly approach.

Coil Spring Modification Technical Engineering Essay

Coil Spring Modification Technical Engineering Essay A vehicles appearance can be improved by lowering the car height. This can be achieved by heating or cutting the coil springs. However, this modification can have effects on the vehicle wind resistance, centre of gravity and reduce excessive body role. This modification contributes in fuel efficiency and better handling. It can also have negative impacts and could cause a big damage in the vehicle as well as being unsafe for the passengers if not done properly. Compression springs are the cheapest coil spring to manufacture, they are built to withstand the forces of linear compression or pushing forces that makes them as the most durable type of coil spring available. The coil springs are made of heavy gauge steel wire that is used to support the vehicle. The ends are designed to be flat because of the applied evenly force at each end of the spring, decreases the buckling tendency, or to provide exact seating requirements and solid height reduction which may be compulsory by specific uses (Kiwi Springs limited, 2008). Coil springs usually have three types of ends which are: Tangential end: this type of spring will fall over if someone stands on its end because the end of the coils end remains to twist off in the space Tangential End Coil Spring Square end: the end of this design permits the spring to stand still when placed on the end because the end coil curves back down and touches the coil below it . http://www.budzter.com/images/adjusterPics/DSC00479_Small.jpg Pigtail end: this spring has the sort of square type end and contains a smaller diameter than the coil in the body of the spring http://pitstopusa.com/images/T14599086.jpg (EATON Detroit Springs, 2011) Theory Generally, the end design of the spring can tell straight whether it is safe to cut or not, which concluded that pigtail end and square end coil springs cannot be safely cut. As mentioned briefly above, cutting or heating the coil spring in the vehicle may have some implications in terms of structural integrity, drivability or road worthy aspects. Cutting the coil spring affects the spring rate to increase, stiffen it and making the handling and ride a bit firmer, this is caused by the spring design rule which uses the wire diameter and the number of coil to define the spring rate. The unit for spring rate is pound per inch (lb/in) which means amount of force needed to compress the coil spring by 1 inch. For example when cutting springs by more than 2 inches of the front suspension of the 60s or 70s Chevy without following the specifications, many problems can occur, things such as ground clearance difficulties, positive camber will be gained at an increasing rate as well as suspension traveling may be less effective. It is known that cutting a spring by 1 inch will cause the ride to get lower between 1.5 and 2 inches because of the spring ratio which is 1.5:1 and 2:1 (Smith, 2008) When having too soft spring rate the whole suspension system may be affected because the vehicle will keep on bouncing off the bump stops, while having too much spring rate can create lots of bouncing and cause the tires to lose the grip with the road. Also spring load can affect the suspension system because of the carried weight that a coil spring supports at any moment compressed height. For instance if we use a 10 tall inch spring at free height with 200 lb/in rate, with a compressed height of 6 inches, the support will be around 800 pounds at that height (De Los Santos, 2009) How do we calculate the spring rate? By using the following formula we are able to find out the spring rate of the compressed spring. K = Where k = constant pound of load per inch G = modulus of rigidity of spring material, pound per square inch d = wire diameter, inches n = number of active coils, which is the number of coils subjected to flexure (always less than the total number of coils) D = mean coil diameter, inches = Outer diameter Wire diameter http://www.engineersedge.com/spring2.gif (Engineers Edge, LLC, 2011) Experimental method In this project, the modification will be for lowering the car. Hence we are going to modify the 1995 Impala SS (Appendix 1). This modification will be simply achieved by cutting the springs. This will result in reducing the free length and spring height. Since we do not have access to the real material, this modification will be done in a virtual way by using calculation. Data: number of active coils = 6.5 inches Wire diameter = 0.685 Outside diameter of spring = 5.4375 inches Free length = 16.5 inches Compressed length = 14.05 inches By using the formula above, the conclusion of the spring rate will be 443.76 pounds/ inches (as on the appendix 1). If we want to modify this spring, we will cut one coil that will decrease the number of coils from 6.5 inches to 5.5 inches of active coils, outside diameter and wire diameter will remain the same and free length will change from 16.5 inches to 15.5 inches and compressed length from 14.05 to 13.05 inches. Results: K = = 11,250,000 x 0.6854 / 8 x 5.5 x 4.75253 K = 524.44 pounds/inch The result from the modification shows that the spring rate has been increased by 80.68 pounds/inch. According to Law Volume Vehicle Technical Association (Inc), (2000), states that no modification for changing the height of the vehicle should be done without the spring manufacturer and the heat method should not be used during the modification (Appendix 2). AA New Zealand allows modification of the road springs or shock absorbers if they are fitted as a direct replacement for the originals and should be fitted exactly the same way without raising or lowering the vehicle. Modifying the vehicle without a professional certifier could prevent the vehicle from getting WOF (Appendix 3). Discussion It is essential when modifying the coil spring to consider what reason we are modifying the spring. Other aspects that need to be considered are spring rate, spring index, total share stress and spring axial deflection. The whole suspension system might not perform as it should if proper procedures are not followed. Safety regulations should also be the main priority at all times when dealing with coil spring modification and the suspension system in general. Conclusion According to the results of the experiment in this report, it can be seen that by decreasing the spring height, the spring rate increases. By cutting the spring, we change the appearance of the car to be closer to the ground. It is very important to understand the disadvantages and advantages of what we are trying to achieve. It is also necessary for the driver to understand the change the modification will bring when using the vehicle in different environment. If the user is not able to tell the effects of modification, it is recommended to see a professional. References De Los Santos, H. (2009). Lowering Your Car Properly.

Free News in a Linked World Essay -- Internet Web Media Papers

Free News in a Linked World We usually classify communication media in three categories: published media, broadcast media and what Chris Chesher calls â€Å"invocational media†.1 The published media include newspapers, magazines and books. Radio and television are broadcast media — I would add speech as a nontechnological broadcast medium also. Invocational media represent communication tools used on interactive and networked digital computers.2 News delivery is present on every communication medium. I will look at the difference in value of the content between the media. And I will explain how the World Wide Web — as a new invocational medium — will bring back a public discourse based on logic and reason. And how it will re-democratize the libertarian press. Comparative Descriptions In published media — the oldest technological news distribution method — news is provided on a physical support on which alphabetical characters and images are printed. The support — a newspaper for example — must be distributed, and the user must acquire it. There is a sense of possession, of ownership evoked by the object. The content is made of texts, photographs and illustrations. It is self contained and can be consulted anywhere, at any time and in any way. Broadcast media are part of late nineteenth and twentieth century’s technological innovation. The technology behind broadcast news is based on linear streams of communicative content emitted from a base and transmitted through different means — copper cable or wave for example. To be able to view or hear the news, the user must acquire a receiving machine. Content is sent in real time and has no physical representation.

Life of Pi :: essays research papers

Having just experienced the sinking of his family’s ship, and being put onto a life boat with only a hyena, Pi felt completely lost and alone. When he sees Richard Parker, the Bengal tiger from his family’s zoo, it is a familiar face to him. His initial reaction is to save the life of his familiar friend so that he may have a companion, and a protector aboard the lifeboat. Suddenly Pi realizes just what he is doing. He is saving the life of Richard Parker, by welcoming him, a 450 pound Bengal tiger, onto the small lifeboat. He experiences a change of heart when helping the tiger onto the boat. Pi realizes that he is now posing a threat on his own life. With Richard Parker on the boat, Pi is faced with not only the fight to survive stranded in the middle of the Pacific Ocean, but the fight to survive living with a meat eating tiger. The change of heart that Pi experiences might possibly mean that he is an impulsive thinker. It may mean that he often does something on im pulse without thinking it through, and then later regrets his actions. How does Pi maintain his religious beliefs while on the boat?   Ã‚  Ã‚  Ã‚  Ã‚  Pi maintains his religious beliefs while on the life boat through his daily prayers. He takes time aside each day to say the prayers that he always would say. In one instance, he turns where he believes Mecca is located, and prays his traditional prayers towards Mecca. Pi also often states that he will include specific animals in his prayers, such as the zebra aboard his lifeboat, and the first fish that he ever killed. With Pi keeping his ritual prayers going, it helped him to survive.

Discuss the training requirements for Higher Level Teaching Assistants (HLTAS)

1) Discuss the training requirements for Higher Level Teaching Assistants (HLTAS). Higher level teaching assistants (HLTAS) have a variety of training requirements to adhere to for example numerical and literacy skills up to NVQ level 2 which ensures that they are able and confident in what they are teaching. HLTAS should also have a broad knowledge of learning strategies from independent to group within the curriculum to allow a pupil to fulfil their potential.HLTAS should also have a solid knowledge of the curriculum along with skills in curriculum development and delivery this is to allow HLTAS to be able to teach to a high standard and be aware of what a pupil needs to do to get them to move up a sub level or level in different subjects. In addition to this most HLTAS are required to have experience with the children that they are assigned to work with whether this be young children teenagers, special needs or gifted and talented.It is also recommended that HLTAS have a sound kno wledge of ICT to allow this to be implanted across the curriculum and in order to adhere to certain procedures within the school such as using behaviour programmes online or for cross curriculum to be implanted. Policies and procedures are also required for HLTAS to be aware of and able to draw upon when and if needed, also to allow HLTAS to know the policies the school has on safeguarding, bullying and many others.HLTAS should also be confident in regulations and laws surrounding the area in which they are working with whether this be the every child matters act or the children in care act for LAC children. HLTAS should be able to discuss development stages form birth to teenager including speech and language stages. HLTAS should also be confident administering assessments as well as marking them with the correct levels which is why HLTAS need a sound knowledge of the curriculum so that they are able to do this. HLTAS should also have good organisation skills in order to keep the c lass running smoothly and that all procedures are followed.HLTAS should have good self-evaluation skills in order to look at their teaching critically in order to reflect on it and improve. Furthermore HLTAS should have good team work skills so that they can share planning teaching and evaluating themselves and other within the team also for support within the school environment. 2) What are the National Occupational Standards (NOS)? What purpose do they serve? The National Occupational Standards (NOS) are performance standards that specify what skills and knowledge a HLTA should have in order to perform in their role.NOS provide a valuable resource to schools that use them to assist in the creation of job descriptions and roles and responsibilities, as well as underpinning training, progression and supporting development needs of staff. They were developed by representatives and different employers in a variety of sectors within education. HLTAS can target the use of the national o ccupational standards in a variety of ways from supporting and assisting with the development of frameworks used for the organisation, promoting and supporting equal opportunities to ensuring confidentiality but to name a few.Other National occupational standards are applicable to HLTAS from roles outside of education for example self-assessment for competence and opportunities for professional development and improvement of skills all of these help staff and HLTAS be able to perform their role to a correct standard and increase their competency within their role. HLTAS can use the National Occupational Standards to Measure their performance, knowledge and understanding against a nationally agreed checklist.Which in turn helps them to see where they need to develop their skills, knowledge and understanding in a variety of different areas, furthermore to help HLTAS decide what skills, knowledge and understanding they will need to progress in their career and for contentious professio nal development. The HLTA role is at the centre of the national occupational standards for supporting teaching and learning, with the standards reflecting the larger scope of responsibilities that the role now holds.Many standards are relevant to my job role with tasks beyond the level one job description, such as, working with children who have special educational needs, implementing IEP’S and Behaviour plans being undertaken along with a new amount of paperwork such as annual reviews for statemented children and the uptake of APP and target framework for example despite the task and descriptor ‘Monitor pupil’s responses to learning activities and accurately record achievement/progress as directed and Provide detailed and regular feedback to teachers on pupils achievement, progress, problems etc.  Ã¢â‚¬â„¢ (Veronica, W :2003) being on a level 2/3 job description it is usually undertaken by many level 1 teaching assistants.3) How do Higher Level Teaching Assist ants support children in schools? HLTAS support children in a variety of ways in the school community, for example a Higher Level Teaching Assistant (HLTAS) assess the needs of a child which can be done from the HLTA performing assessments to administering test. HLTAS also should serve as a good role model for children which in turn help to support and encourage relationships between children and their personal and educational environments.HLTAS should also help children and teachers set high expectations for children to boost performance and self-esteem. Supporting and developing systems of rewards and consequences which should help a child learn right from wrong. HLTAS should get to know the child/children they are working with and support them in their learning environment whether it be IEPs, behaviour support to literacy and numerical support. HLTAS also support in planning

Three Possible Learning Theories Integrated By AIU Online Within The Course

I. IntroductionAmerican intercontinental University has adopted various learning theories to cater for the needs of everyone in the world. These theories include: Gagne’s conditions of learning, the importance of structuring and sequencing of instruction, the socially mediated aspects of learning, individual construction of knowledge through experience and external constraints, experiential knowledge resident within and among adult learners and fostering deep learning.II. Background on LearningLearning is a gradual change in behavior due to practice or experience.  Some proponents who have studied this are Gagne, Reigeluth and Piaget.III. Theories.A. Conditions of learning by Gagne who was an American Psychologist. In his findings and research realized that there is a great connection between learning objectives and appropriate instructional designs. In 1965 he published the book that categorized learning into five taxonomies; 1. Category is verbal information: this is very important in learning process since it will provide the learner with an opportunity to take in the information, analyze it into a meaningful context and encode it to his/her own understanding.2. There are intellectual skills which are required in any learning. To define, classify or apply a concept to solve any problem. 3. Taxonomy is cognitive strategies which the learner employs his or her ways in learning, thinking and doing things. 4. Taxonomy is attitudes; this will enable the learner to use personalized actions to solve normal daily problems. 5. The use of motor skills, one must use what he/she has learnt to perform certain actions using muscles. B. Elaboration theory which shows importance of selecting, structuring and sequencing information.Reigeluth (1979) gave the principles for planning and organizing instruction. Whereby, the instruction must be organized in order of complexity for optimal learning. The learner should develop meaningful concepts to base subsequent ideas and skills. C. Theory fostering deep thinking by Piaget. Piaget said that, there is need to foster deep learning. This enables the students to capitalize in emerging opportunities and be able to meet the ever changing demands of employees.IV. Active Learning Strategies and Exploratory Learning StrategiesThe types of active and exploratory learning strategy include: investigating a system using personal initiative to a real or artificial task, studying a controlled setting with special attention to newly acquired systems, using diaries and structured interviews that focus on learning events, field study, task-oriented explorations, using support from manuals/users/system support personnel and designing a system, and training.V. Electronic Learning Support Technologies There are different learning supports available like; Electronic based facilities, resources and services that are always available.These may be mobile learning, e-learning, web based, interactive television, cable tele vision, video conferencing and use of emails. VI. Conclusion The entire process is highly connected to the theories of learning for instance; Gagne’s theory of conditions of learning is highly implemented because of verbal communication. Materials are structured and sequenced this is in tandem with Reigeluth elaborative theory. The need to foster deep learning is evidenced in use various electronic learning support.

Introduction to Business

Wednesday November 1 3, 2013 Homework Chapter 1 1 Professor: Mr. B Introduction to Business Rudy V. Garcia Chapter 1 Who will be the various stakeholders of your business? Pedestrians All High School, Middle School and Elementary Schools students around my neighborhood Churches Attendants Charter Schools attendants All local commerce of my area of performance What are some of the things you can do to benefit your community other than providing Jobs and tax revenue? Provide affordable prices Use local providers Do not use products that contain G. M. O (Genetically Modify Organisms) OfferScholarship programs for high scholars with low income How will you establish good relationships with your suppliers? With your employees The best I can offer is a relationship based in honesty and integrity. Also I will take the time to the needs of my employees and work to meet those needs. Do you see any conflict between your desire to be as profitable as possible and your desire to pay employees a living wage? I believe that we reap what we saw. If I am truly involve with the well-being of my employees; they will not only work tor what I pay them tor; they will engage hemselves in the company and be more profitable.Which of the environmental factors outlined in this chapter might have the biggest impact in your business? How? Competing by restructuring and empowerment will be the most difficult area I will have to deal with more than anything. I believe building a team that moves according to the needs of the business is a hard but possible goal; the process to bring together people to work towards one specific task requires time, money and patience. Chapter 2 U. S. Supreme court ruled that cities could have school voucher programs that give oney directly to parents, who could then choose between competing schools, public or private.The idea was to create competition among schools. Like business, schools were expected to improve their services to win students from competitors . The result would be improvement in all schools, private and public, to benefit many students. Do you believe economics principles like competition apply in the both private and public organizations? Be prepared to defend your answer. Yes, I do. Competition opens the door for creativity. I believe that when people immerge themselves into a ompetitive environment they tend to get more creative and also work hard to achieve a goal.Are there other public functions that might benefit from more competition, including competition from private firms? The Law System Transportation Education System Many people say that businesspeople do not do enough for society. Some students choose to go into the public sector instead of business because they want to help others. However, businesspeople say that they do more to help others than nonprofit groups do because they provide Jobs for people rather than giving them charity. Furthermore, they believe businesses create all the wealth that nonprofit groups distribute.How can you find some middle ground in this debate to show that both businesspeople and those who work for nonprofit organizations contribute to society and need to work together more closely to help people? Both are important and complement each other. Business provide the way of creating wealth and nonprofit make society remember to reach out for the less fortunate. Businesses push people to achieve success and thru nonprofit we are reminded that the ultimate level of uccess is achieve by a persona only when this persona gives back to his/her community.How could you use the concepts of Adam Smith to help illustrate your position? Well if we can guide business to be more involve in the community they are surrounded by; business will create more wealth that will impact the lives of the community at the same time. Government will exist only to promote and incentive companies to give back to the community that have make them successful. Chapter 3 About 95% of the wo rld's population lives outside the United States, but many U. S. ompanies, especially small businesses still do not engage in global trade.Why not? Do you think more small businesses will participate in global trade in the tuture. 7 Why or why not? Global trade demands to spend lot money in resource such as advertisement, licenses, taxes, etc. These expenses make the process hard for small businesses to Join global trade. If the governments around the world approve laws that allow small business to enter in the global trade at a low cost I believe there is chance we can see small companies entering in global trade market.Countries like he United States that have a high standard of living are the referred to as industrialized nations. Countries with a lower standard of living and quality of life are called developing countries (or underdeveloped or less developed countries) what factors prevent developing nations from becoming industrialized nations? One of the mayor problems is the lack of resources such as technology, leadership, not production orientated, disadvantage in global trading, they not own bigger enough ways of massive production, corrupted law systems and economical systems.What can businesses do to prevent unexpected problems in dealing with ociocultural, economic and financial, legal and regulatory, and physical and environmental forces in global market? The best way will be to stay in touch with the needs of their client and ayes open to what the market is requiring to exist. Always being open to enter in new fields and achieve a top creativity vision that allows them to transform themselves to the market. How would you Justify the use of revenue or protective tariffs in todays global market? They lack objective and most of them are doing to elite corporations.

Parts of Speech Essay

When the idea of the traditional eight parts of speech comes to mind, flashbacks to sitting in the back row of my middle school English language class flourish through my brain. I don’t remember too much about them today, however I do know that it was drilled into my brain until we could fully understand and use them all. The eight parts of speech: such a key component of language, yet such a complicated piece of my learning career. Out of all eight of the parts of speech, the verb, the noun, the pronoun, the adjective, the adverb, the preposition, the conjunction, and the interjection, the ones that I remember the most are the verb and the noun. I am not quite sure how such basic ideas of language can be so complicated to actually explain. My previous days of schooling were definitely not the most challenging or puzzling. So how is it that I use these in depth concepts in daily conversations? I honestly think that in my earlier school days, we simply discussed all of these eight parts of our language and never actually were shown how they are all connected. As I look back now, the approach to teaching the basic patterns of the English language, such as these key parts of speech, have never been too effective. These parts of speech constantly keep being brought up in my daily life yet somewhere along the lines, we get caught up in simply knowing the parts of speech rather than being able to use them effectively on our pieces of written work. All of these great facts have no purpose if we are unable to use them in our daily lives. Reminiscing back to this seemingly simple concept really does stress how important proper grammar and knowing how to make the eight parts of speech useful truly is. As a student entering the world of learning again, the importance of being a good writer and being well-spoken increasingly influences my life. To be a good writer is one thing, to honestly know what you’re trying to portray through your work is a completely different idea on it’s own. Being knowledgeable about the parts of speech and how they can be used in many facets of language is fantastic. Naming the parts of speech in isolation does not bring focus to how important these words can be, but knowing how to effectively use them in writing is what truly is important. These eight  concepts of writing came up all throughout the early years of my educational career and they’re importance is brewing back up once again in my life. Concepts in language never go away, making them one of the most important and best things you can ever learn, just hopefully this time they can stick!

A Case Analysis On Arik Air Nigeria Commerce Essay

A Case Analysis On Arik Air Nigeria Commerce Essay This essay is a case analysis on Arik air Nigeria and will therefore seek to identify the major threats and opportunity in the environment, analyse the strength and weakness of the company, identify the strategic position of Arik air, and suggest a strategy to be adopted by the airline in an effort to sustain its competitive advantage. BACKGROUND Arik Air is Nigeria’s biggest indigenous commercial airline offering domestic flights to major cities in Nigeria and with an expanding network of regional and international flight operations to major cities in the world (Eze, 2010). Presently, Arik Air flies to 17 Domestic destinations in Nigeria and 8 International destinations (Arik air, 2010: Online). Arik Air Nigeria The company’s corporate mission is: ‘To be a safe and reliable airline by selecting and operating new, modern aircraft and by employing the most experienced and efficient staff.’ (Airkair, 2010: Online) Vision: ‘To make Nigeria proud of its aviation industry’ (Arikair, 2010: Online) Strategic Intent: Arik’s strategic intent is to be the preferred airline carrier of choice in West Africa. (Airk Air, 2010: Online) EXTERNAL ANALYSIS: The external analysis was conducted using PESTEL Framework and Porter’s five forces as the basic tools (Thompson, 1997; Luffman et al, 1996; Welsh, 2005; Johnson et al, 2009) in an effort to understand the effect of changing environment on Arik Air’s operation. The findings based on pestel framework (See Appendix 1) and Poster’s five forces (See Appendix 2) are as follows: An analysis of the political environment revealed that governments around the world are tightening immigration regulations due to the surge in terrorism the implication of which is a reduction in the number of global traveller thus posing a threat to airline including Arik Air. (Stevermen, 2009; Cartar, 2010). However liberalization and Deregulation efforts are being made in several regions of the world with Asia setting a target for the full liberalization of its skies by the year 2015. This is projected to boost aviation industry performance by creating avenue for fair competition platform between more established airlines and the growing competitors like Arik Air(Bailey, 1986; Smith Ting, 2008). The rising fuel price is a matter of economic concern in the world, with Aviation fuel price estimated at $85 per barrel (IATA, 2010: online) the implication of which is an increase in running cost for airlines and this poses a high threat to Airlines. However, there is optimism that a global economic recovery is on the way with the world economy expected to grow 2.7% in 2010 (World Bank, 2010: Online) and the aviation industry is forecasted to reduce its loss from $5.8 Billion in 2009 to $2.8 Billion in 2010. (Financial Times, 2010). The World travel & tourism council (2010) projects an increase in the number of holiday travellers in 2010 with further growth expec ted in 2011. The 2010 world cup is expected to boost travel to Africa in 2010 (Eberl, 2010).

International stll wine trade Essay Example | Topics and Well Written Essays - 500 words

International stll wine trade - Essay Example Data is the information that is gathered for analyzing, interpreting and making conclusion based on the available information. The source was from â€Å"database of international business statistics† which is accessed across the countries. The important features in the research are the demand and the years of the product production. The first then observations show the demand of the product in the market prior to the introduction of globalization. The subsequent years shows the impact of globalization to the product demand. One of the limitations is the misuse of the data. This involves the use numbers in a biased manner so as to suit the researchers predetermined hypothesis and hence ease in making conclusions that are not scientifically justified. The wrong numbers used lead to misleading graphs and charts being drawn and this encourages error in conclusions (Boudreaux 2008). Statistics are normally based on probabilities hence the results vary from when the each variable could have been used. This makes the results to be amendable and/or provisional. The data collection is always narrowed by moral, financial and practical constrains that affects the conclusions to be drawn. The statisticians/researchers are do not completely agree on superlative methods hence inconveniences. Data manipulations required before estimation is the arrangement of the data in an increasing total over the years of trading. The demand for the products over the periods of marketing should increasing conform the validity of the analysis (Selkirk 2012). The last ten observations highlight the impact of globalization on demand and the sales of the company product. The total sales amounted to 2701M, a mean sale of 245.55M, a median sale of 246M and a mode sale of 262M. From the above descriptive statistics, it is clearly shown that the total sales have increased substantially overtime i.e. from sale of 1177M to 2701M. This is 1524M sales increment

On the other hand, the parent company may enter into a contract with another firm whereby, that firm is given mandate to offer services either locally or in the foreign market (Avadhanam, para.4) 2). Skill premium is where the wages earned by both skilled and skilled labors who works in the same field increase relatively to each other. The skilled premium in the U.S has widened wage gap between skilled and unskilled labor for the past 30years (Kannan, p.115). 3).The effects of outsourcing on workers’ wages include; it reduces the wages earned by workers, skilled workers may obtain more wage benefits as compared to the unskilled. Finally, it causes suffering to workers who worked at outsourcing firms. 5).It is true that U.S skilled workers fear the security of their jobs due to possibility of outsourcing. This because a firm may find cheaper to outsource labor rather than utilize local labor (Kannan, p.136) 1). The three factors that make Kenya an attractive site for Business Process Outsourcing include: availability of the 3 fiber optic cables, emergence of 4 undersea cables and availably of highly skilled labor force (The Economist,

Causal Arument Essay Example | Topics and Well Written Essays - 1250 words

Causal Arument - Essay Example Some states legally allowed the use of marijuana for some diseases for which the doctors prescribed it as a medicine whereas some other states are still not allowing even the patients to use or keep marijuana under their possession. However, according to medical experts, marijuana use should not be encouraged because of the side effects it can generate later in the user’s life. â€Å"To date, marijuana is still classified as an illegal Schedule 1 drug by the Controlled Substances Act. It is defined as having "no accepted medical use in treatment in the United States" (Roth). American Federal courts are still convinced about the usefulness of marijuana. For them, marijuana is still an addictive and dangerous substance which can damage a person physically and psychologically. Spice, a herbal smoking mixture, is sold on the internet and in some shops in America labeled as legal and nicotine-free smoke. Many people in America are using Spice at present as a substitute to Marijuan a. However, scientific studies shown that Spice is also harmful to human health. Professor Leslie Iversen, chairman of the technical committee of the Advisory Council, said: â€Å"It is a very clever product, sold as a herbal smoking mixture from China, but containing chemicals which can be a lot more potent than cannabis† (Ford). This paper analyses the Spice as legal alternative to marijuana. Cannabis has been used for relaxation and meditation purposes for many thousands of years, and studies carried out today tell us the number of users is rising. Young people especially seem to be attracted to experimenting with mind-altering drugs, such as cannabis, and this can result in abuse, addiction, mental health problems, and prosecution. While cannabis itself is not physically addictive it can be dangerous for those with mental health issues and is often supplied by dealers who also have access to harder, highly addictive drugs (Casundara) â€Å"Herbs or blends of herbs that o ne can smoke as alternatives to marijuana or tobacco- The term marijuana alternatives mean just that. It does not mean we are offering legal marijuana or a marijuana substitute† (Legal Alternatives To Marijuana And Tobacco). Many people who are using Spice like alternate products instead of Marijuana have feeling that these products are less harmful than marijuana and it is legal to use these products in America. In fact Spice like substitute products for marijuana has not been prohibited in America yet and hence no criminal cases can be charged against such users. However, it doesn’t mean that these substitute products are less harmful or superior to marijuana. The only advantage of using spice like alternate product is that the user can escape from any kind of legal formalities in using it. According to a shop owner, â€Å"the demand for spice has doubled each month, and its sales now represent a third of his revenue. On some Fridays, his two District stores can brin g in $10,000 from the sale of spice alone†(Savage). The growing popularity of Spice over marijuana can be attributed mainly to the fewer barriers in getting it in America. No drug screening tests can detect Spice which made it one of the favorite substitutes for marijuana. Many of the Spice users believe that it is less harmful. However, â€Å"Nationwide, the American Association of Poison Control Centers logged 567 cases across 41 states in which people had suffered a bad reaction to spice during the first half of 2010. Just 13 cases were reported in 2009†

Why obesity a serious problem and how should we solve it Essay - 1

Why obesity a serious problem and how should we solve it - Essay Example To some extent, obesity has also contributed to the loss of work hours in the work places not to mention the billions of dollars used annually in managing those with obesity (EOPUS). Concerns have been raised over the contribution of fast food companies like McDonald in the development of obesity. They have been accused of giving adverts that do not contain warning signs as that of cigarette and that thus the contribution of fast food to the worsening human population in America is comparable to that of the cigarette, which was fiercely fought in America generation after generation (Kava, Gilbert, and Elizabeth, 34). Obesity is thus feared to be taking the lead as one of the health hazards in the US particularly among the children and if remained unchecked, the country will not only spend much of their resources in medication but will also lose a significant segment of their population (Washburn, 98). This paper has considered the following essays on obesity to assert the dangers associated with obesity. In the essay, Zinczenco starts by recounting in his own life experience about the separation of his parents that made him lead latchkey life. From school he did not have any option but to seek the services of the fast food stores; MacDonald, Taco Bell, Pizza Hut, and Kentucky Fried Chicken. This kind of life he says made him develop obesity but thanks to his joining one of the Health Magazines that prompted in him the need to take precautionary measures in the type of food he eats. He enumerates the problems that come with obesity and the statistical report from the Center for Disease Control about the expenses incurred by the government in treating obesity related diseases. The writer also gives a substantial recount on the children who have filed a civil litigation about the companies that are dealing in fast food for contributing to their worsening health. He takes

Marginal analysis Essay Example | Topics and Well Written Essays - 750 words

Marginal analysis - Essay Example He begins by putting diversity into perspective and conceding that high levels of diversification brings earnings loser to economic profits of zero; at this point, economic equals accounting profits less the opportunity cost related to capital. In making the diversification move, Rudow explains that GU made two main investment decisions; the first one was to purchase Jin Xin Copper Company Ltd giving it 67% ownership through its partially owned subsidiary-Engen Investment (EI). The second was the purchase of an extra 8% through the same subsidiary from other shareholders; Gold Hero and Silver Harvest (Rudow, 2011). In this whole transaction, Rudow explains, marginal analysis compels compelled GU to evaluate the true cost each investments and make isolated judgments. Given the purchased company was Chinese, investments costs were absorbed in levels of business entities with independent costs that must all be considered to come up with real returns of which he carefully analyzed. He clarified in the article that the income statement alone cannot account for relevant costs since numerous capital allocations were buried in the balance sheet, and only by carrying out a marginal analysis, is GU able to clearly determine real returns in this diversification venture. Since recycled copper will from this deal be a primary source of revenue, GU is now able to mitigate problems from contacting biodiesel business segment. In this article, D Cohen looks at Welsh Health Planning Forum recognized 10 health gain areas with the help of marginal analysis. This analysis, he explains, examined the outcomes of changing the present balance of expenditure between the various healthcare programs. To achieve this, he further explains that resources are discharged from disinvestments to support chosen investment programs so that the entire strategy is resource neutral. The overall achievements in health benefits as a result of this strategy

Issues in International trade Essay Example | Topics and Well Written Essays - 1250 words

Issues in International trade - Essay Example They include consultancy and tourism among others. A product sold in the international market is an export while a product bought from the same market is an import. Trade issues often dominate and are a continuing theme in the international market. The issues include NAFTA, embargoes, sanctions, and the environment, trade deficits, The Euro, tariffs and WTO among others. Some of the issues are discussed as follows: A reduction in trade barriers allowing for integrated global economies and permitting international trade will affect the environment through the expansion of economic activities. It alters the composition and make-up of economic activity by bringing about a change in the techniques and means of production. The course of consideration and for environmental protection was raised by environmental groups on the potential North American Free Trade Agreement (NAFTA). This was just the first of a far cry to other voices opposing international or regional trade on the possible effects it may have on the environment. It is seen that an increase in international trade is detrimental to the objective of preserving a clean, healthy and sustainable global environment. It has been argued that any expansion of market to a global scale, ultimately leads to the environmental pollution and faster depletion of natural resources. These natural resources are scarce in nature. For example, international trade of coal has made it easier for countries to acquire it for economic activities. Coal has been known as a leading environmental pollutant. International trade has facilitated the growth of industries whose primary objective is the export of goods to the international market. For example, the United States has promoted several of such agreements such as the African Growth and Opportunity Act (AGOA) and the NAFTA. These agreements have led to the rapid growth of industries that have little government oversight and control. These

Properties of Gases Essay Example for Free

Properties of Gases Essay Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid, mossy zinc, Bromothymol blue, limewater, Manganese, and Alka Seltzer, to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar, baking soda, water, and hydrogen peroxide in order to create the gases to be tested. Materials: Student Provided 1 Match 1 Toothpicks (or wooden splints) 1 Pie tin or similar 1 Marker pen 1 Household white vinegar 1 3% Hydrogen peroxide (H2O2) 1 Measuring spoons 1 Drinking straw 1 Tissue paper 1 Baking soda (sodium bicarbonate) From LabPaq 1 Goggles-Safety 1 Test Tube (5), 13 x 100 mm in Bubble Bag 1 Well-Plate-24 Auxiliary Supplies Bag Auxiliary Supplies Bag- CK1 1 Gas Assembly; copper/plastic tubing in #00 Stopper 1 Pipet, Empty Short Stem 1 Rubber stopper, #00, 1 hole, Pipet tip w/plastic Gas delivery tube Experiment Bag Properties of Gases 2 Alka Seltzer ® (1/4 tablet) in Bag 2 x 3 1 Bromothymol Blue, 0. 04% 4 mL in Pipet 1 Hydrochloric Acid, 2 M 20 mL in Dropper Bottle 1 Limewater (Calcium Hydroxide, Saturated) 6 mL in Pipet 1 Manganese Metal Pieces 4-6 Pieces in Bag 2 x 3 3 Pipet Bulbs, Wide-Neck with 1/4 Stem 1 Zinc, Mossy 4-6 Pieces in Bag 2 x 3 Procedure: 1) Hydrogen a) I placed a small amount of ZN( mossy zinc) in the test tube containing HCL b) I then capped the test tube with the small cap that allowed gas release from the top and placed it in one of the 24 well plates. I wedged the test tune in with a bit of toilet paper. c) I then filled the large stem pipet with water and placed it atop the rubber stopper. d) I placed the well plate in a pie tin to prevent the overflow from getting everywhere. e) After the water was replaced entirely with hydrogen I removed the wide mouthed pipet and placed my finger over the opening to prevent any gas from escaping. f) I lit a match and while holding the pipet about 1cm away from the flame blew the gas onto the flame, and recorded my observations in the table. g) With a marker I marked the wide-neck pipet on the outside into three parts h) I filled the bulb with water and set it on the test tube as before. i) Once the bulb was 2/3 full of gas I removed it and placed it aside, still inverted, for later use j) I then disassembled and rinsed the tools and threw away the ZN. 2) Oxygen A) I placed a few pieces of Mn (Manganese) into the second test tube. B) I filled the test tube to within 1cm of the top with hydrogen peroxide. Afterwards I placed the rubber stopper on the test tube and the test tube in the well plate. . C) I then filled another wide-neck pipet completely with  water and placed it on the top of the stopper in the test tube. D) After the water was displaced I removed the pipet and placed my finger over the opening to prevent any gas from leaking. E) I lit a match and extinguished it. While the match was still glowing I placed it inside the pipet and recorded the reaction. 3) Hydrogen and Oxygen Mixture A) I took the pipet from part 1 that is partially filled with hydrogen and placed it on the generation test tube from part 2. B) I let the bulb fill until the water was completely displaced. The mixture was about 2/3 hydrogen and 1/3 oxygen C) I removed the bulb and placed my finger over the open end to prevent any gas from escaping D) I lit a match, held the pipet horizontally about 1cm away from the flame and squeezed the gas onto the flame. E) I recorded my observations in the table. F) I disassembled the test tube washed the contents down the drain and rinsed the tools. 4) Carbon Dioxide A) Part I a) I placed approximately .5 ml of limewater in one well of the 24 well plate. b) I placed  ½ a teaspoon of baking soda in the generation test tube. c) I filled a pipet halfway with vinegar and added it to the baking soda. Immediately after the two stopped reacting I placed the rubber stopper with the copper and plastic gas delivery tube on the top of the test tube. d) I placed the open end of the tube into the well with limewater and recorded the reaction. B) Part II a) I placed approximately .5ml of Bromothymol blue in one of the wells. b) I thoroughly rinsed the gas generation test tube with water and set up another test with baking soda and vinegar as in part 1. c) After putting the stopper in place I inserted the open tube into the Bromothymol blue. d) I removed the stopper from the generation tube. e) I lit a match and inserted the flame into the upper part of the test tube. f) I recorded my observations. C) Part III a) I poured the chemicals down the sink and flushed with water. b) I put approximately .5 ml of limewater into another well. c) I crumbled the small piece of Alka Seltzer into a test tube d) I added one pipet full of water to the test tube and immediately inserted the stopper with the gas delivery tube. e) I placed the open end of the tube into the limewater well. f) I washed the test tube and well thoroughly with water. D) Part IV a) I put approximately .5 ml of limewater into a test tube. b) I inserted a straw and blew for a few seconds. c) I recorded my observations d) I washed the tools and flushed the limewater down the sink. Results: Gas Flame reaction Glowing splint Limewater reaction Bromothymol blue reaction Hydrogen Loud sound, flame went out n/a n/a n/a oxygen n/a Light up quickly dissipated and glowed for around 10 seconds n/a n/a Hydrogen oxygen Popping sound and flame went out n/a n/a n/a Carbon Dioxide n/a n/a Changed the color of the limewater from clear to nearly milky, bubbled rapidly.

First we do this because maximizing the pressure in the tube will maximize gasses. Secondly because this causes there to be a shorter distance for the gases to traveled B) What happens to the zinc in the hydrogen generation experiment? The mossy zinc causes a reaction with the HCL to form hydrogen gas. C) What happens in the oxygen generation experiment? The manganese reacts with the hydrogen peroxide to form oxygen. D) Write a balanced equation for the reaction between O2 and H2. 2H2 +O22H2O E) What is the function/purpose of the Bromothymol blue in the CO2 experiment? The Bromothymol blue in the CO2 experiment is used to indicate how much CO2 is in the solution. It indicates this with a color change. F) Bromothymol blue is blue in the presence of basic solutions and yellow in the presence of acidic solutions. If your solution is a murky green, what  might you assume about the solution I would assume the solution was neutral. Conclusion: In conclusion, I learned that properties of gases vary vastly in their reactions with flame, and other substances. I also learned how to create such gases in a controlled environment for future experimentation. The effect of these reactions put into perspective how dangerous gases can be and how their proper storage and transportation is a vital essential in our daily lives. Seeing the different reactions will make me more cautious of the way I materials.
