Rhetorical Analysis Of Our Gas Guzzlers, Their Lives Essay

Simon Yang Tompkins English 101 9/24/15 Rough Draft: Rhetorical Analysis on â€Å"Our Gas Guzzlers, Their Lives† In his article â€Å"Our Gas Guzzlers, Their Lives† Nicholas Kristof writes about Africa, specifically the country of Burundi. Crop failure and water shortage are causing or will cause all sorts of major problems. These environmental changes are linked directly to us, and the greenhouse gases emitted through non eco-friendly vehicles. Using the rhetoric tools of ethos, pathos, and logos he clearly makes his case of how essential it is to stop or at least reduce the carbon emissions we produce. Kristof has strengths and flaws in all his rhetoric tools especially in his pathos, and his ethos which is damaged by the setup of the article. First of all, one of the most heavily used instruments in this article, pathos, is very effective, but certainly has its flaws. Every example about how the lives of the people in the poorest country in the world are being jeopardized by the gases that our cars produce is compelling. Kristof states, â€Å"†¦Changing weather patterns in recent years have already caused crop failures-and when the crops fail, people starve† (564). He has simplified the whole process of how the gases go from the cars to ultimately killing these people. It’s a very long process, but when he puts it this way, the effects of the cars seem to be killing off Burundi immediately. However, his pathos can be seen through at some points to be more of a guilt trip to stopShow MoreRelatedRhetorical Analysis of Kristof792 Words   |  4 PagesBoyer-White 2/10/11 Rhetorical Analysis of Kristof Nicholas Kristof wrote a compelling article titled â€Å"Our Gas Guzzlers, Their Lives†.

Plant Layout Free Essays

LAYOUT Facility layout is an arrangement of different aspects of manufacturing in an appropriate manner as to achieve desired production results. Facility layout considers available space, final product, safety of users and facility and convenience of operations. An effective facility layout ensures that there is a smooth and steady flow of production material, equipment and manpower at minimum cost. We will write a custom essay sample on Plant Layout or any similar topic only for you Order Now Facility layout looks at physical allocation of space for economic activity in the plant. Therefore, main objective of the facility layout planning is to design effective workflow as to make equipment and workers more productive. Facility Layout Objective A model facility layout should be able to provide an ideal relationship between raw material, equipment, manpower and final product at minimal cost under safe and comfortable environment. An efficient and effective facility layout can cover following objectives: * To provide optimum space to organize equipment and facilitate movement of goods and to create safe and comfortable work environment. * To promote order in production towards a single objective * To reduce movement of workers, raw material and equipment * To promote safety of plant as well as its workers To facilitate extension or change in the layout to accommodate new product line or technology upgradation * To increase production capacity of the organization An organiza tion can achieve the above-mentioned objective by ensuring the following: * Better training of the workers and supervisors. * Creating awareness about of health hazard and safety standards * Optimum utilization of workforce and equipment * Encouraging empowerment and reducing administrative and other indirect work Factors affecting Facility Layout Facility layout designing and implementation is influenced by various factors. These factors vary from industry to industry but influence facility layout. These factors are as follows: * The design of the facility layout should consider overall objectives set by the organization. * Optimum space needs to be allocated for process and technology. * A proper safety measure as to avoid mishaps. * Overall management policies and future direction of the organization Design of Facility Layout Principles which drive design of the facility layout need to take into the consideration objective of facility layout, factors influencing facility layout and constraints of facility layout. These principles are as follows: * Flexibility: Facility layout should provide flexibility for expansion or modification. * Space Utilization: Optimum space utilization reduces the time in material and people movement and promotes safety. * Capital: Capital investment should be minimal when finalizing different models of facility layout. Design Layout Techniques There are three techniques of design layout, and they are as follows: 1. Two or Three Dimensional Templates: This technique utilizes development of a scaled-down model based on approved drawings. . Sequence Analysis: This technique utilizes computer technology in designing the facility layout by sequencing out all activities and then arranging them in circular or in a straight line. 3. Line Balancing: This kind of technique is used for assembly line. Types of Facility Layout There are six types of facility layout, and they are as follows: * Line Layout * Functional Layout * Fixed Position Layout * Cellular Technology Layout * Combined Layout, and * Computerized Relative Allocation of Facility Technique How to cite Plant Layout, Papers
