Titanic free essay sample

This paper analyzes the movie Titanic from a socio-economic point of view. This paper takes a look at the block-busting move Titanic by James Cameron. It acknowledges that the movie was predominantly a love story, but it also had very strong socio-economic under currents. The paper provides an analysis of these dynamics. From the paper: In 1997, Titanic set sail again, this time into movie theaters under the command of writer and director James Cameron. With the exception of a few small poetic licenses, Cameron accurately depicts the historical events leading up to the sinking of Titanic. The main plot of his movie, though, is not about the sinking of the ship per se. Rather, it is about the doomed love affair between two fictional characters, first-class passenger Rose DeWitt Bukater and steerage passenger Jack Dawson. Complicating the story is Rose?s jealous fiance?, millionaire Caledon (?Cal?) Hockley, and Rose?s genteelly impoverished mother, Ruth. We will write a custom essay sample on Titanic or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Aside from any dramatic appeal, Cameron?s Titanic is interesting from a number of sociological perspectives. It illustrates social classes, status inconsistencies, and social structures. It presents a vivid ?conflict?-based view of the way the different classes relate to one another. And finally, it offers a look at bureaucracy and at the dangers of groupthink.

How to Make Your Book Review More Critical with an Outline

How to Make Your Book Review More Critical with an Outline How to Make Your Book Review More Critical with an Outline? Setting out to write a critical book review is a daunting task. Something about the word ‘critical’ seems to conjure up scary visions of having to wade through huge tomes of literary theory that threaten to swallow your limited analyzing abilities as a student. A review at the end of the day is supposed to be critical where you share your opinion on a specific topic and it tells the makers or readers your honest opinion on it. There are many reviewers out there, criticizing all kinds of books including fiction and essays, but not all these reviewers or their opinions are valued. At times, it is only because they’re lacking a proper outline and hence are not able to write their thoughts properly. Why Have an Outline for a Critical Book Review? Like any other assignment set by a systematically produced curriculum, a critical book review is also easy. You simply apply a systematic approach and break it into parts. You jot down the essential elements you need to include. Working according to an outline is a great way to accomplish your goals. An outline serves as a systematic tool that will keep you on track. You can always refer to your outline to make sure you are not missing anything. Moreover, we mention some tips on actual critical book review writing, so it’s two birds with one shot. This guide will tell you how to prepare an outline in four easy steps which correspond to the recommended sections. Introduction (1-2 Paragraphs, Half a Page) Like any good piece of writing, start with an introduction. The specific form is up to you, choose a quotation that you liked, a particularly powerful scene in the book, even a personal anecdote which ties into the broader opinion you hold of the book. The goal is to capture the reader’s attention and keep them hooked. Include an overview of the book where you summarize the plot and also present an expression of your overall judgment. Summary (1 Page or about 23 Lines of Typed Text) A summary is a brief discussion of the major themes, concepts, and ideas presented in the book. It is recommended that you write this entirely in your own words. Present a condensed picture of the book. If your summary contains spoilers, make sure you warn your readers about it. Critical Evaluation (3 Pages) The third is an in-depth section which includes the reviewer’s reactions to the thoughts of the author. Most students often find it challenging to be critical, probably because they are under the impression that in order to critique something you have to possess expert-level knowledge. This is an unfortunate opinion that must be dispelled from your mind. Conclusion (1-2 Paragraphs, Half a Page) A short section which shows the overall impression and evaluation arrived at by the reviewer. It can be written in first person if desired and should include: Things which you learned from the book; Whether you would recommend the book to other people. A critique is simply a collection of responses, reactions and thoughts to what you are reading. No one expects you to produce an expert-level critique if you are only a learner. The best way to make this easy is to write down your thoughts and impressions while you are reading the book. Jot down any questions or aspects you like and at the end of your read you will have a significant set of notes that will make the critique a breeze. Here are the aspects that you need to include: Your overall opinion and the reasons behind it. How did the book make you feel? Was the writing able to hold your interest? What was the author trying to communicate? How well- or not- did the author present his or her points, ideas and assumptions? Did you detect any underlying philosophy in the book? Is the author’s view objective? How does the book fit into the context of the course? How useful are the footnotes, index, bibliography etc.? Is the book a useful contribution to the field in general? What are the strengths/weaknesses of the book? Do you have unanswered questions from what book? What would you like to add or remove from the book to make it better? You need to mention these questions in your outline to know what to focus on in your writing. Then, while creating the actual book review, formulate these sections as a properly structured essay that includes topic sentences and logical transitions. These outline guidelines are extremely important because the moment you detail them, you’ll have a clear structure in your head. We hope that they will make your book review as critical as possible (in a good way).

Quality Assurance Essay Example | Topics and Well Written Essays - 1250 words - 2

Quality Assurance - Essay Example Total quality control thus means that a system is developed and implemented which delineates the procedures, policies, specifications and standardizations to be followed by the entire organization. This system is developed and continuously improved by maintaining a cross- functional viewpoint at all times involving all the departments: the issue of quality thus becomes the concern of all departments, not that of the quality control department alone. This means quality and process manuals need to be rigorously followed, and updated from time to time based on cumulative work experience to improve productivity and quality. Total quality control also means that the organization is specialized and prefers to work with its core strengths, outsourcing peripheral goods and services to other organizations specialized in those areas: a car manufacturer, for instances, focuses on assembling cars and leaves the business of manufacturing machine parts to its suppliers. Outsourcing in this way is geared to improve efficiency, but may go totally wrong if the goods supplied are not the right quality, or run in short supply. This brings us to the issues crucial to just-in-time inventory management strategies, which are indispensable not only in terms of economy and cost cutting, but also crucial in terms of maintaining control over purchase. Just-in-time implies that a company times the purchase of the correct kind and amount of goods or services exactly as and when needed for its production processes: the right material, at the right time, at the right place, and in precisely required amounts, thus eliminating the need for warehousing or other infrastructure. This ensures that a lot of expenses made on storage are eliminated, which is absolutely according to the principles of total quality control that insists on continuous identification and eradication of waste in a company's manufacturing process. Having no inventory to call from, it obviously follows that all the goods procured have to be of a quality level certified for use in the manufacturing process, otherwise the process gets delayed or experiences frequent stoppages. Possible supply shocks also need to be prevented by anticipating changes in demand for the goods required for the process, so that the process does not come to a halt because of lack of material f or processing. Certified quality levels in goods purchased from vendors can only be maintained if the total quality regimen extends to supply quality assurance as well. The organization has to work with various entities such as supply stream managers, internal customers, technical staff, relevant field personnel, and last but absolutely not the least, suppliers. These different groups need to be integrated as part of on-going supply management processes, which may include product and supplier selection, assessment, and providing support in quality and performance improvement. Since the supplier needs to be top-notch with all its goods each and every time, it follows that the purchasing organization would have to invest in training, auditing and testing, and build up a great, long-term relationship with hand-picked vendors. The organization woul

Football Essay Example | Topics and Well Written Essays - 1250 words

Football - Essay Example What is driving sports in the world is more than just fun. In the new era, sport has become a combination of management, responsibility, skill-development, rivalry, strategy, fitness and many more aspects one can think of as this domain can not be limited or confined to a few principles. Football Stadiums are all over the world and people do not hesitate to fill in the stadiums regardless of what so ever the match is. This sport brings in much revenue as well. A single ticket in Manchester for a match between the famous rivals Manchester United and Arsenal can cost well over 500 which is way above many developing economies' GDP per capita. At this stage, the concept of a "Team" is most important. The word team does not refer only to a group of people combined to accomplish a task rather it is an association of individual who socialize and cope with each other's differences to reach the "maximum" achievable. A team consists of members that have different skills so each can be a specialist in any one desired area. The team members also have complementary skills to coordinate well and imply synergy so as lessen or hide an individual's weakness in that of the team's strength. The highlight of the modern sport is "Football". It is the most popular sport of the world. It has players from all across the world. Lets see what football is and how did it trace its origin. Our predecessors have been accustomed to playing a game/sport that involved kicking the ball around a specified area and targeting a desired point. The issue was that one team had to put the ball through and the other had to stop. In the early times the sport was played by almost every Race, Tribe, Stronghold but the rules varied a lot. So we can say that football has been a global sport for quite a time. The earlier versions were the "Chinese game of cuju" and the "Harpastum" as played by the Romans. The need to develop standardized rules was felt in the mid 19th century as the sport was gaining much popularity and was spreading. The first to come up were the Cambridge Rules as many British schools ought to play the game thus uniformity was required. Research Methodology The research will be based on surveys and short interviews with general people from different areas. Selecting this methodology will bypass any bias present in the research. The problem would be to classify the data into groups and arrange it accordingly. The surveys would be internet based and some site visits. We can easily find Football fans across the world and so it would be feasible if shopping Malls are targeted for this purpose. The survey would consist of small questionnaire placed at the exit of the Mall and the public would be required to just give in a few minutes answering the questions if they are interested. Further at other convenient places, small interviews highlighting the sporting events and globalization of Football will be undertaken by an experienced interviewer such that the results could be analyzed and summarized easily. Selection Feasibility Why have I chosen this topic is because Football requires

Response paper to this qustionIn Candide, what are the various Essay

Response paper to this qustionIn Candide, what are the various attitudes, ideas, and behaviors that Voltaire is lampooning - Essay Example Voltaire's Candide shows the complete transformation of philosophical idelogoly of Pangloss that this is the best of all possible worlds. This may clearly fit to a person someone like Candide who is not aware of the outside world other than his baron's castle. But in reality, world is full of misery and corruption. The change in the mindset of a person depending on the situation is rightly presented throughout the process as he sees corruption and violence all over the world. It must be noticed that Voltaire has criticized the ideology of various characters and has tried to enlighten us about the real world. Candide is an exemplary work by Voltaire as he brings to light the behavior of various characters and criticizes the philosophies and ideologies of various religions like Roman Catholic Church, Islam and others. The idea of free will is questioned by an individual's control over his own destiny. Voltaire criticizes the idea of free will through Candide as a person is predestined to act irrespective of the fact whether he is doing good or evil. The main notion as stated by Pangloss that "there is no effect without a cause' and "we live in the best of all possible worlds and whatever happens is for the best' is strongly ridiculed as there is lot of violence and bloodshed resulting in loss of lives.

Application Of Types Of Lubricant

Application Of Types Of Lubricant A lubricant is a substance (often a liquid) introduced between two moving surfaces to reduce the friction between them, improving efficiency and reducing wear. They may also have the function of dissolving or transporting foreign particles and of distributing heat. Basically there are many types of lubricants; solid lubricant, liquid lubricant and gaseous lubricant. They have their own purpose and application. They are as follows: Purposes: Almost all the Lubricants perform the following key functions. Keep moving parts apart Reduce friction Transfer heat Carry away contaminants debris Transmit power Protect against wear Prevent corrosion Seal for gasses Stop the risk of smoke and fire of objects Applications: Application of Semisolid and Solid Lubricants Grease lubricants are semisolid and have several important advantages: They resist being squeezed out, they are useful under heavy load conditions and in inaccessible parts where the supply of lubricant cannot easily be renewed, and they tend to form a crust that prevents the entry of dirt or grit between contact surfaces. Grease is a mixture of a lubricant and a thickener; often it is made from a mineral oil and a soap. It may be applied in various ways: by packing enclosed parts with it, by pressing it onto moving parts from an adjacent well, by forcing it through grease cups by a spring device, and by pumping it through pressure guns. Solid lubricants are especially useful at high and low temperatures, in high vacuums, and in other applications where oil is not suitable; common solid lubricants are graphite and molybdenum disulfide. Application of Liquid Lubricants Liquid lubricants may be characterized in many different ways. One of the most common ways is by the type of base oil used. Following are the most common types. Lanolin (wool grease, natural water repellant) Water Mineral oils Vegetable (natural oil) Synthetic oils Other liquids Mechanical devices to supply lubricants are called lubricators. A simple form of lubricator is a container mounted over a bearing or other part and provided with a hole or an adjustable valve through which the lubricant is gravity-fed at the desired rate of flow. Wick-feed oilers are placed under moving parts, and by pressing against them they feed oil by capillary action. Horizontal bearings are frequently oiled by a rotating ring or chain that carries oil from a reservoir in the bearing housing and distributes it along the bearing through grooves or channels. Bath oiling is useful where an oil-tight reservoir can be provided in which the bearing journal may be submerged; the pool of oil helps to carry away heat from contact surfaces. Splash-oiling devices are used where gears, bearings, or other parts contained in housings have moving parts that dip into the lubricant and splash it on the bearings or into distribution channels. Centralized oiling systems usually consist of a reserv oir, pump, and tubes through which oil is circulated, while heaters or coolers may be introduced to change the viscosity of the lubricant for various parts of the system. Many oiling operations are automatically synchronized to start and stop with the machinery. P2) Describe the operation and maintenance of three different lubrication systems. Oil lubricating systems can be divided into three categories: Total loss. Self contained. Re-circulating. Total loss: lubrication points are always supplied with fresh lubricant (oil, fluid grease or grease) at specific intervals (time or machine cycle-dependent) during the lubricating cycle. It is the only system that allows the lubricating oil to drain away or evaporate. Self contained : With self contained lubrication, the oil is contained in a reservoir. A gearbox of a vehicle or a lathe is lubricated in this way. The gear are partly submerged in the oil, this process is called splash lubrication. Oil is carried up to the parts that are not submerged, and an oil mist is created inside the gearbox. Ring oiling is another self contained system in which the oil from a reservoir is carried up to the rotating parts of a mechanism. The ring which is rotating with a shaft is partly submerged in the oil and carries it up to the shaft bearings. Re-circulating: With re-circulating system, the oil from a reservoir is fed under pressure direct to the moving parts or delivered as a spray. The flow is continuous and after passing over the contact surfaces, the oil runs back into the reservoir under the effects of gravity. Maintainance: Oil lubrication systems should be checked weekly. This can be carried out by plant operators or maintenance engineering. If needed the tank or reservoir can be topped up taking care not to let any dirt into the system during the process. Systems should not be overfilled as this might caused increases resistance to splash lubricated parts. It might also lead up to overheating of the oil due to excessive churning. Dip sticks and sight gauges are usually provided to indicate the correct level or depth in reservoirs. Samples of lubricating oil are taken for laboratory analysis at regular intervals as part of a condition monitoring procedure. They are examined to see if they contain any solid wear particles. This can provide useful information to the plant manager and maintenance engineer as to the condition of the plant and machinery. All lubricating oils degrade over a period of time due to oxidation. They should be changed including the filters in a re-circulating system. Human should be careful of lubricating oils, since it can cause skin irritation, it can also lead up to cancer. So humans should always use safety equipments and should also wear protective clothing and maybe goggles for the eyes, when handling lubricating oils. References: http://en.wikipedia.org/wiki/Lubricant, engineering book P3) Describe the operation of one seal, one type of packing and two different types of bearing with a typical application for each one. Seals: For the task , I will be doing oil seal. Oil seals are flange packing having an elastomer lip bonded to a metal cup, these lips are loaded to accommodate shaft running out and helps in sealing. There are two types of oil seals. Single seals , which are recommended only for non-pressure service and are best against good lubricating media. And the other one is double sealing, which are normally used to handle pressure in eiher direction along the shaft. The main function of oil seal is to stop whatever fluid is inside from leaking out the clearance between the shaft and housing. Packing For packing, I will be explaining about gland packing seals. they are usually made of cotton, asbestos, flax or jute. In this packing, compressed synthetic fibers are also used and sometimes impregnated with graphite to assist lubrication. It has the advantage to withstand higher internal pressures than lip seals. in this packing, a collar is tightened so that packing material forms a seal around the shaft. A little amount of water for lubrication and cooling the packing is also allowed to drip to the atmosphere. It is normally used as a seal for both rotating and reciprocating shafts. Bearing: The purpose of the bearing is to support and locate rotating and reciprocating shafts or parts in machines and is to transmit force from one member to the other while allowing their relative motion/ movement to occur with the minimum resistance to motion. Two bearing I will choose for this task are plain bearing and roller bearing. Plain bearing: it is a typical bearing made of two parts. For e.g. a rotary plain bearing can be just a shaft through hole. A simple bearing can be pair of flat designed to allow motion. It has flat , cylindrical or spherical surfaces which slide relative to each other. It can be used to carry load in one of several ways depending on their operating conditions, surface, clearance and temperature. It may be used to comprise a rotating collar with a flat surface loaded against a plain or grooved thrust ring. It is also designed to withstand the forcve acting along the axis of the shaft, parallel to the axis of rotation. Roller bearing: this bearing carries a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding. A rolling element rotary bearing uses a shaft a much larger hole and cylinders called rollers tightly fill the space between shaft and hole. The bearing are often used for axles due to their low rolling friction. References: handout given by teachers P4) Describe two different types of screwed fastening and two different types of rivet giving a typical application for each one. Screwed fastening are used to make semi permanent joints which allow access and removal of fastened parts for maintenance and/or repairs. There are many types of screwed fastening of which the two I am going to mention here are nuts and studs and set screws. stud and nuts: it is a length of bar which has been threaded at each end, the shorter threaded end is screwed into the major component. It is used for inspecting machine cover needs to be removed regularly for maintenance purpose. Set screws: it is also known as machine screws however it does not used a nut. It is usually used to join a thin plate to a larger component. Screws are available with different shapes of head for different applications. It can be used as locking devices. P6)Describe the arrangement and operation of two different kinds of belt drive, two different kinds of chain drive and two different kinds of gear train. A) Belt drive: A belt drive is a method of transferring rotary motion between two shafts. A belt drive includes one pulley on each shaft and one or more continuous belts over the two pulleys. The motion of the driving pulley is, generally, transferred to the driven pulley via the friction between the belt and the pulley. Synchronous/timing belts have teeth and therefore do not depend on friction. Belt drives and gear transmissions have a much greater life expectancy than belt drives. Belt drives also have relatively high inspection and maintenance demands. There are many types of belt in which I am going to explain two of them; 1) Round belts Round belts are a circular cross section belt designed to run in a pulley with a circular (or near circular) groove. They are for use in low torque situations and may be purchased in various lengths or cut to length and joined, either by a staple, gluing or welding (in the case of polyurethane). Early sewing machines utilized a leather belt, joined either by a metal staple or glued, to great effect. 2) Ribbed belt A ribbed belt is a power transmission belt featuring lengthwise grooves. It operates from contact between the ribs of the belt and the grooves in the pulley. Its single-piece structure it reported to offer an even distribution of tension across the width of the pulley where the belt is in contact, a power range up to 600 kW, a high speed ratio, serpentine drives (possibility to drive off the back of the belt), long life, stability and homogeneity of the drive tension, and reduced vibration. The ribbed belt may be fitted on various applications : compressors, fitness bikes, agricultural machinery, food mixers, washing machines, lawn mowers, etc B) Chain drive: Device widely used for the transmission of power where shafts are separated at distances greater than that for which gears are practical. In such cases, sprockets (wheels with teeth shaped to mesh with a chain) take the place of gears and drive one another by means of a chain passing over the sprocket teeth. The chains used in conveyor belts are commonly block chains, and consist of solid or laminated blocks connected by side plates and pins. The blocks engage with teeth on sprocket wheels. Depending on the material being moved, buckets, hooks, or other devices are connected to the blocks. 1) Roller Chain: Motion transmitted using shaft mounted sprockets. Simplex chain consists of length of single links, duplex is length of double links, triplex is length of triple links. Chain drives should ideally be lubricated and regularly cleaned . However experience shows that this drive method will work for long periods without lubrication or maintenance 2) Inverted Tooth: Also called silent. Motion transferred via shaft mounted pinions (similar to gear wheels.) Higher power power capacities, higher speeds and smoother operation. These drive system definitely requires lubrication. (Oil bath, or spray.) C) Gear train: A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide. It is a set or system of gears arranged to transfer rotational torque from one part of a mechanical system to another. 1) Simple Gear Train:It is made of few components, a small gear at the centre called the sun, several medium sized gears called the planets and a large external gear called the ring gear. The planet gear rolls and revolves about the sun gear and the ring gear rolls on the planet gear. 2) Simple Gear Train:The most common of the gear train is the gear pair connecting parallel shafts. The teeth of this type can be spur, helical or herringbone. The angular velocity is simply the reverse of the tooth ratio. The main limitation of a simple gear train is that the maximum speed change ratio is 10:1. For larger ratio, large size of gear trains are required. The sprockets and chain in the bicycle is an example of simple gear train. P7 Describe the arrangement and operation of two different kinds of transmission shaft and coupling, two different kinds of clutch and two different kinds of brake transmission shaft rotating shaft that transmits rotary motion from the engine to the differential Different types of shafts: Plain transmission Stepped shaft Machine tool spindle Railway rotating axle Non-rotating axle Crankshaft Propeller shaft Crankshaft The crankshaft is that part of an engine which converts linear piston motion into rotation. The crank and connecting rod mechanism was first used in Roman water mills, to convert the reciprocating motion into rotation, the crankshaft has crank throws or crankpins. More than one piston is attached to the crank to provide a smoother delivery of power to the rotating part, though many small engines such as those found in garden machinery, use only a single piston. The configuration of pistons in relation to each other and the crank and their number leads to descriptions such as straight-4 (four pistons in direct line), V6 or V8. Transmission shafts sizes vary from 10 to 100mm but it can go higher then these figures, the maximum length of shaft usually does not exceed 7m. Propeller shaft Propeller shafts transmit power between the source and the machine, the propeller shaft assembly consists of a propeller shaft, a slip joint, and one or more universal joints. This assembly provides a flexible connection through which power is transmitted from the transmission to the live axle. Axle is similar in shape to the shaft and support bending movements only. The propeller shaft may be solid or tubular. A solid shaft is stronger than a hollow or tubular shaft of the same diameter, but a hollow shaft is stronger than a solid shaft of the same weight. A slip joint is put at one end of the propeller shaft to take care of end play. The driving axle, attached to the springs, is free to move up and down, while the transmission is attached to the frame and cannot move. Couplings A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By using couplings, savings can be made in reduced maintenance costs and downtime. Thompson coupling Thompson coupling is a constant velocity universal joint that can be loaded axially and continue to maintain constant velocity over a range of input and output shaft angles with low friction and vibration. It consists of two cardan joints assembled within each other, so eliminating the intermediate shaft along with a control yoke that geometrically constrains their alignment. The use of cardan joints within the Thompson Coupling is to reduce the wear, heat and friction. The Oldham coupling The Oldham coupling transmits rotary motion between shafts that are parallel but not always in perfect alignment. Oldham couplings consist of three members, a floating member is trapped by 90 displaced grooves between the two outer members which connect to the drive shafts. Oldham couplings can bear lateral shaft misalignments up to 10% of nominal shaft diameters and up to 3 angular misalignments. Clutch: A clutch is a mechanism for transmitting rotation, which can be engaged and disengaged. Clutches are useful in devices that have two rotating shafts. In these devices, one shaft is typically driven by a motor or pulley, and the other shaft drives another device. Friction clutch: it connects two separate pieces of shaft, it also has levers and springs to disengage/engage plates. The primary disadvantage of friction clutches is the regular maintenance and adjustment that are required, mating parts will wear due to friction (resulting in slippage), springs will lose memory, and other parts will need replacement or adjustment. Positive clutch: A clutch designed to transmit torque without slip. It consists of two mating surfaces with interconnecting elements, such as teeth, that lock together during engagement to prevent slipping. Positive clutches are also known as mechanical lockup clutches. Brake: A specific type of clutch that slows and stops motion by engaging a rotating shaft and a fixed component. Disc brake The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel. A brake disc (or rotor in U.S. English), usually made of cast iron or ceramic composites (including carbon, Kevlar and silica), is connected to the wheel and/or the axle. To stop the wheel, friction material in the form of brake pads (mounted on a device called a brake caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop. Brakes (both disc and drum) convert friction to heat, but if the brakes get too hot, they will cease to work because they cannot dissipate enough heat. This condition of failure is known as brake fade. Hydraulic brake The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit, which is usually near the operator of the vehicle, to the actual brake mechanism, which is usually at or near the wheel of the vehicle. P8 Describe with the aid of diagrams the general layout and operation of a pneumatic actuation system, a hydraulic actuation system and a mechanical handling system Pneumatic autuation system: A pneumatic actuation system is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. With the pressure controller, It can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The educator can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the educator to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes. Fig. example of pneumatic aculator. Hydraulic actuation system: A hydraulic system for a sterndrive marine propulsion device directs the flow of hydraulic fluid through the body and peripheral components of a gimbal ring in order to reduce the number and length of flexible hydraulic conduits necessary to conduct pressurized hydraulic fluid from a pump to one or more hydraulic cylinders used to control the trim or tilt of a marine drive unit relative to a gimbal housing. Mechanical handling system: Mechanical handling is simply a row of roller/cylindrical or triangle cross-sectional component. They are mostly covered by a long belt but it is not necessary. The rollers or what ever it is used are rotating and the product/component will be moving along and the other rollers will pull it along like the image is shown below. The component/product will move until it reaches its destination or the end of the roller P9 Describe with the aid of diagrams the general layout and operation of a steam power generation plant, a refrigeration system and an air conditioning system. refrigeration system BASIC REFRIGERATION PRINCIPLES If you were to place a hot cup of coffee on a table and leave it for a while, the heat in the coffee would be transferred to the materials in contact with the coffee, i.e. the cup, the table and the surrounding air. As the heat is transferred, the coffee in time cools. Using the same principle, refrigeration works by removing heat from a product and transferring that heat to the outside air. REFRIGERATION SYSTEM COMPONENTS There are five basic components of a refrigeration system, these are: Evaporator Compressor Condenser Expansion Valve Refrigerant; to conduct the heat from the product In order for the refrigeration cycle to operate successfully each component must be present within the refrigeration system. The Evaporator The purpose of the evaporator is to remove unwanted heat from the product, via the liquid refrigerant. The liquid refrigerant contained within the evaporator is boiling at a low-pressure. The level of this pressure is determined by two factors: The rate at which the heat is absorbed from the product to the liquid refrigerant in the evaporator The rate at which the low-pressure vapour is removed from the evaporator by the compressor To enable the transfer of heat, the temperature of the liquid refrigerant must be lower than the temperature of the product being cooled. Once transferred, the liquid refrigerant is drawn from the evaporator by the compressor via the suction line. When leaving the evaporator coil the liquid refrigerant is in vapour form. The Compressor The purpose of the compressor is to draw the low-temperature, low-pressure vapour from the evaporator via the suction line. Once drawn, the vapour is compressed. When vapour is compressed it rises in temperature. Therefore, the compressor transforms the vapour from a low-temperature vapour to a high-temperature vapour, in turn increasing the pressure. The vapour is then released from the compressor in to the discharge line. The Condenser The purpose of the condenser is to extract heat from the refrigerant to the outside air. The condenser is usually installed on the reinforced roof of the building, which enables the transfer of heat. Fans mounted above the condenser unit are used to draw air through the condenser coils.The temperature of the high-pressure vapour determines the temperature at which the condensation begins. As heat has to flow from the condenser to the air, the condensation temperature must be higher than that of the air; usually between 12Â °C and -1Â °C. The high-pressure vapour within the condenser is then cooled to the point where it becomes a liquid refrigerant once more, whilst retaining some heat. The liquid refrigerant then flows from the condenser in to the liquid line. The Expansion Valve Within the refrigeration system, the expansion valve is located at the end of the liquid line, before the evaporator. The high-pressure liquid reaches the expansion valve, having come from the condenser. The valve then reduces the pressure of the refrigerant as it passes through the orifice, which is located inside the valve. On reducing the pressure, the temperature of the refrigerant also decreases to a level below the surrounding air. This low-pressure, low-temperature liquid is then pumped in to the evaporator M1) . Compare and contrast the operation and uses of flat plate clutches, centrifugal clutches and fluid couplings in mechanical power transmission systems flat plate clutches centrifugal clutches fluid couplings The fluid coupling is operated simply by a hydraulic fluid and the driver bladed wheel. The driver wheel rotates and rotates the fluid in between follows it along and cause the driven bladed wheel to rotate along the hydraulic fluid. The hydraulic and driven bladed wheel are still under motion even if the driver bladed wheel stops. The friction disc is sandwiched between the machined surfaces of the flywheel and the pressure plate when the pressure plate is bolted to the outer edge of the flywheel face. The clamping force on the friction facings is provided by the diaphragm spring. Unloaded, it is a dished shape. As the pressure plate cover tightens, it pivots on its fulcrum rings, and flattens out to exert a force on the pressure plate, and the facings. It is used in gears, turbine and many more. A clutch operated by centrifugal force from the speed of rotation of a shaft, as when heavy expanding friction shoes act on the internal surface of a rim clutch, or a flyball-type mechanism is used to activate clutching surfaces on cones and disks. Weights wherein each weight has an arc-shaped clutch shoe and is pivotally mounted with a lever foot on a carrier disc on the drive end of the clutch. After reaching a specific rpm, the clutch shoes are pressed under the action of centrifugal force against the inner wall surface of a clutch drum for providing friction-tight torque transmission. The clutch drum surrounds the clutch shoes. The centrifugal clutch includes a carrier disc on which the centrifugal weights are pivotally mounted. A cover disc is held axially tight at the sides of the centrifugal weights which lie opposite the carrier disc. This cover disc radially covers the clutch shoes so that axial guide play is provided. It is used in generators. Device used to transmit rotating mechanical power. It has been used in automobile transmissions as an alternative to a mechanical clutch. There is no mechanical interconnection between the impeller and the rotor (i.e. the driving and driven units) and the power is transmitted by virtue of the fluid filled in the coupling. The impeller when rotated by the prime mover imparts velocity and energy to the fluid, which is converted into mechanical energy in the rotor thus rotating it. It is used n aviation, engineering companies and many more. M2) Compare and contrast the operation and use of pneumatic and hydraulic actuation systems Pneumatic autuation system: A pneumatic actuation system is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. With the pressure controller, It can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The educator can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the educator to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes. pneumatic actuator system provides the advantage of lower weight and more economical construction. One distinct adv antage of a pneumatic system is that it may utilize a source of bottled gas or the like as a potential energypower source. Fig. example of pneumatic aculator. Hydraulic actuation system: A hydraulic system for a sterndrive marine propulsion device directs the flow of hydraulic fluid through the body and peripheral components of a gimbal ring in order to reduce the number and length of flexible hydraulic conduits necessary to conduct pressurized hydraulic fluid from a pump to one or more hydraulic cylinders used to control the trim or tilt of a marine drive unit relative to a gimbal housing. advantages of pneumatic acutators over hydruallic actuators Relatively cheaper. The force transmitter, air, is freely available. Cleaner system as air leakage do not create a mess. Hydraulic oil becomes very hot after continuous use. Can cause injury if someone comes in contact. Generally have open circuits and we dont have to worry about the return circuit. Justify the use of Shell Tellus oil 27 lubricant and the splash lubrication system in the lathe machines in the College machine shop. Shell Tellus Oils oil 27 are premium quality hydraulic oils generally acknowledged to be the standard-setter in the field of engineering hydraulic and fluid power lubrication. The Shell Tellus oil 27 lubricants are mineral oils.It has an active anti-corrosion additive effectively protects hydraulic systems from corrosion. Water collects in the lubrication system due to condensation with soluble cutting fluid and is emulsified to provide further protection. It has excellent anti wear which means that lathe machine can be used for longer unlike other lubricants, it also helps improve the efficiency of filtration systems to reach system cleanliness targets.The dirt can also clean easily off. The lubricant provides anti-war and increase the resistance of the lathe material surface. It also helps to operate under high temperature; actually it works as a coolant. The lubricant also does a quick air release without excessive foaming. Other point is that the lubricant has very low environmental impact because of the zinc free technology. It also doesnt react with other chemical when it is in use. Shell tellus oil 27 has high lubrication properties and excellent low friction characteristics in hydraulic systems operating at low or high speed. Prevents stick-slip problems in critical applications enabling very fine control of machinery.

The Sanctity Of Oaths In Medea :: essays research papers

Medea The Sanctity of Oaths Through the play Medea, Euripides shows us the importance of keeping a promise given. At the beginning of the story, we see the play's two opposing views of promise keeping represented by the Nurse and the Tutor. As she stands outside of Medea's house and laments the way Jason has slighted Medea by taking another wife, the Nurse speaks of the 'eternal promise'; Jason and Medea made to each other on their wedding day (17-21). The Nurse wishes Jason were dead for the way he has abandoned his wife and children, so strongly does she feel vows should not be broken (83). When the Tutor enters the scene, he expresses a much more cynical view regarding Jason's decision to leave his wife. He asks the nurse, 'Have you only just discovered / That everyone loves himself more than his neighbor? / Some have good reason, others get something out of it. / So Jason neglects his children for the new bride'; (85-88). The Tutor feels that Jason's leaving Medea is only a part of life, as 'Old ties give place to new ones';. Jason "No longer has a feeling'; for his family with Medea, so he leaves her to marry the princess who will bring him greater power (76-77). Medea is outraged that she sacrificed so much to help Jason, only to have him revoke his pledge to her for his own selfish gain. She asks him whether he thinks the gods whose names he swore by have ceased to rule, thereby allowing him to break his promise to her. Medea vows to avenge her suffering by destroying Jason's new family and his children. When Jason curses his wife for her murdering at the end of the play, she says to him, 'What heavenly power lends an ear / To a breaker of oaths, a deceiver?

Paganism vs Christianity

Pagan vs. Christian The holy Catholic Religion had a drastic Christian like impact on the barbarian, Viking Pagans of the Anglo-Saxon Age in England (Elements of Literature 11). The Catholics evolved the aggressive Pagan Vikings into a peaceful society (Williams). Also, the Catholics substituted their warlike religion and after-life to a more holy and Christian like religion (Chaney 197-217). Along with the altering of the Pagan society and religion, the Catholics also transformed the Pagans dominant government style to a more civilized and unified one (Williams).The Pagans did not expect their society, religion, and government would be shifted to a Christian like style, but it did (Elements of Literature 11). The calm Catholics transformed the brutal Pagan Vikings into a more civilized society (Williams). After the transformation the Pagan’s tribal like communities was changed to towns with Castles (Williams). Also the Pagan’s tradition of oral literature being told by the scop was changed to written language in which the monks wrote (Williams).The unimportance of women in the Pagan society was changed when Virgin Mary the patriot saint helped raise the status of women (Williams). Along changing the type of society the Pagans were accustomed to into a more modern one like the Catholics there was also a change in religious beliefs (Elements of Literature 11 ). The Pagans believed in a warrior death and after-life while the Catholics believed in a holy peaceful religion, this was another alteration the Catholics made upon the Pagans (Chaney 197-217).The Pagans believed there was many gods and the best place to go after death was Valhalla while the Catholics believed in one God and Heaven was the best place after death (Chaney 197-217). The Catholics had an idol to live up to which was Jesus, the son of God, while the Pagans fought in battle to please Valkyries, whom was said to be the person who chose who died in battle (Chaney 197-217). The Pagans lived to die in battle, they believed dying in battle was heroic, the Catholics believed in living a sin free life and living a peaceful after-life (Chaney 197-217). Along with the changing of the Pagan’s arbarian society and warrior like religion the Catholics also evolved their tribal government into a more modern type (Elements of Literature 11). The Pagans believed in the strongest warrior being the King, or leader of the tribe, while the Catholics believed God chose who the heir to the throne would be (Williams). The Pagan king was known to be the bravest of all warriors but Catholics substituted the bravery for education and began to educate the Pagans (WIlliams). The Catholics also crated a Parliament in the Pagan tribe, which was something they lacked before ( WIlliams).Pagan warriors believed the strongest of all died to protect the king after the Catholics had an impact of their lifestyle it was believed there was a Diving Right of King (Williams). The Catholics un ified England with their transformation of the Pagan lifestyle (Elements of Literature 11). In the end the Pagans resulted in a peaceful society in which provided a common system of morality (Elements of Literature 11 ). The Catholics also provided the Pagans with a common faith of Christianity in which was more peaceful (Chaney 197-217).The most important gift the Catholics gave to the pagans was the transformation of a warrior leader to a militant but yet strategic leader to run a more civilized government (Elements of Literature 11). The calm Christians of the Catholic religion had a positive influence on the barbarous Pagans off the Anglo-Saxon Age in England ( Williams). Although there were many changes made to the Pagan lifestyle there were many more that needed to be made in order for them to be a more civilized nation of what present day England is like today (Elements of Literature 11).

Operational Decision Making

Operational Decision Making Company Description Rotana Jet Aviation, also known as Rotana Airways, is one of the leading domestic airlines in the United Arab Emirates. This airline company has its main operating base in Al†Bateen Airport, which is about 10 kilometers from Abu Dhabi City. The company offers travel services to both the domestic and international passengers.Advertising We will write a custom assessment sample on Operational Decision Making specifically for you for only $16.05 $11/page Learn More The company has been keen to offer quality services to its customers. This is reflected in its mission statement that says, â€Å"To offer quality travel services to domestic and international travelers at reasonable costs.† The company has been experiencing growth in the market, especially after adding new international routes to the previously existing routes. Description of Operations It is important to understand the operational activities of Rotana Jet, and the m eans through which it turns its inputs into output. As stated above, this firm offers travel services to its clients in the market. One of the main inputs of this firm is the planes used to deliver the service. The firm purchases the planes (input) which it uses to offer the travel services (output) to the clients from one location to another. Another important input that the firm has been using is the entertainment facilities, especially the music system fitted in the seats. This input is used to offer entertainment services to its clients. The firm uses coffee, water, and sugar as inputs, to make coffee as the product for its clients while on board their planes. As Bruce (40) observes, the current competitive market in the airline industry is forcing the airline companies to offer better quality products in order to attract a pool of loyal customer. This explains why Rotana Jet is keen on offering their clients drinks and entertainment services. Another important input that this f irm uses in its operations is the human labor, which includes pilots and cabin crew. The pilots work to ensure that clients are flown from one location to another, while other cabin crews work as a team to ensure that the journey is more enjoyable for the customers. Supply Chain Decisions In the current competitive market, firms are keen to ensure that they employ the best strategy in their supply chain management. This is because they are under pressure to ensure that they are efficient in their operations. Sauter (73) observes that there is need to ensure that acquisition of raw materials, their movement to the firm, and distribution strategies used by a firm are very efficient in order to increase profitability.Advertising Looking for assessment on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Rotana Jets has been keen to ensure that its supply chain is managed appropriately to deliver the desired results i n the market. The diagram below shows some of the most important activities that the operations manager will be concerned with in supply chain management. The products, especially the jets will be coming directly from the manufacturer to the firm. Once this is received, the firm will use the input to offer travel services to the customer. Operations manager will always need to make a decision of whether to make such orders through well-established agents in the market, or to contact the manufacturer directly. This decision will always be guided by the associated costs. One of the main strategies that this firm has been using in the market to increase its productivity is cost leadership. This means that Rotana Jet’s operations manager would determine the options available in the supply chain, and determine the associated costs at each stage in the activities identified above. The firm would then make a decision on the option that is most efficient and cost effective. Accordin g to Sauter (51), in supply chain management, firms are always concerned of the best approach to use in order to ensure that they get inputs in time and at the most desirable plans so that a chain of other activities can begin. Given the cost leadership strategy that this firm has been using, it is important for the operational manager to ensure that the decision on the approach to take in acquiring the inputs is conscious of these factors. The management should ensure that the product is always ready whenever the customers need them. Operational Decisions Understanding critical operational decisions within a firm is one of the ways through which a firm can gain competitive advantage in the market (Mahadevan 81). One of the most important critical operational decisions is the choice of product design. Rotana Jet must devise a way to design its products in a manner that will give it an advantage in the market.Advertising We will write a custom assessment sample on Operational Decision Making specifically for you for only $16.05 $11/page Learn More It is a fact that all airlines offer travel services to their customers. However, Rotana must design its products in a unique manner that will help differentiate its services in the market. The management should make a decision to design unique seats, customized entertainment services, high quality customer care, and other unique qualities to its products. These decisions would have a direct contribution to the overall strategy of the firm. The identified decision areas focus on improving quality of services of this firm in the market. They are directly concerned of how Rotana Jet will offer positively unique service to its customers. This means that the operations manager must consider making these decisions out of the desire to offer quality service to its customers at reasonable prices. For this to be achieved, the management must ensure that costs of production are maintained as low as po ssible. Productivity According to Anderson (56), a firm should have a clear way of measuring productivity. This will help it when determining the sustainability of its operations. At Rotana Jets, the need to measure productivity is very strong. This is because of the increasing competition in this market, and the rising costs of production. The main approach of measuring productivity in this firm is through determining the output that is made of the operational activities. The output will be measured through sales made after a given trading period. The firm would then determine the associated costs during that period. The productivity would then be determined by deducting the costs from sales to find the profits. The profits will help in understanding the productivity of the firm. The profits generated should be reasonable enough to sustain operational activities of this company, and be able to foster development. To improve productivity of this company, the operational manager shou ld expand the scope of the firm’s internet marketing to include social media marketing. This is because social media such as Facebook and Tweeter are used by a large number of people who can form part of the customer base of this firm. This strategy will also help this firm create viral marketing in the internet.Advertising Looking for assessment on business economics? Let's see if we can help you!

What Is Model UN 4 Reasons to Join

What Is Model UN 4 Reasons to Join SAT / ACT Prep Online Guides and Tips Are you interested in politics or international relations and looking for a club that lets you do you hands-on activities?Have you heard of Model UN but aren’t sure exactly what it is? Read this guide to learn everything you need to know about what Model UN is, what participants in it do, and how to decide if it’s the right extracurricular for you to join. What Is Model UN? Model United Nations, often referred to as Model UN or MUN, is an extracurricular most commonly for high school students, but also available to college and middle school students. Model UN is a simulation of UN organizations such as theUN General Assembly, UN Security Council, UNICEF, and others. Its participants take the roles of ambassadors from various countries anddebate current issues.Model UNwas developed in the 1950s as a way to give students hands-on learningininternational relations, diplomacy, and the United Nations.Over 400,000 students around the world participate in Model UN each year. What Do Model UN Participants Do? The core of Model UN is its simulations of UN conferences where students (known as Model UN delegates) role playas UN ambassadors and delegates. If you join Model UN, you will be doing a variety of activities, includingresearching,debating, andcoming up with solutions with members of other countries.These simulations occur at Model UN conferences, which can be regional, national, or international. Conferencescan have anywhere from 30 to over 3,000 participants. When your Model UN team joins a conference, your team will be assigned a country and an issue relevant to that country that is currently being discussed in the UN. You can request a certain country, but you are not guaranteed to get it. Forexample, you may be chosen to represent Nicaragua at the Economic Commission for Latin America and the Caribbean (ECLAC). At the conference you attend, you will have to convince the other delegates to make decisions in your country’s favor. If you have a larger Model UN team, you may be assigned multiple countries or issues, and the team will break into smaller groups to cover each one.Conferences occur throughout the year, but you will be given at least a few weeks, and usually several months, to prepare your position before you attend the conference. Before theConference: In order to prepare for conferences, delegates must study the country and the issue they have been assignedandbecome well-informed on both.Most conferences require you to write a position paper that outlines your country’s position on the topic as well as suggestions you have for how to resolve the issue. If you’re representing Nicaragua for the ECLAC, you will need to research topics such as what sectors have the largest impact on the country’s economy, long-term and short-term economic trends in Nicaragua, if there are groups largely excluded from contributing to the economy (such as women or certain ethnic groups), who Nicaragua’s primary trade partners are, what the countryimports and exports, and multiple other topics. After discussing these issues in the position paper, you will have to come up with ways to improve Nicaragua’s economic situation. UN General AssemblyHall in New York City During theConference: Students will be organized based on the committees or councils they are part of, so all the members of the ECLAC would meet together. Each group will have a chair who will moderate the discussions. The chair is often an older student or adult. Delegates then give a speech outlining their country’s position on the issues and offering possible solutions. Most of this information will come from your position paper.After each delegate has presented their country’s position and potential solutions, there are question and answer sessions and debates (known as â€Å"caucusing†). The main goal during the conference is for your committee to develop a written resolution. After you have discussed different countries’ viewpoints, debated, and agreed on solutions, the entire group will work together to writethe resolution. The resolution will explain the issue your committee is focusing on and give a series of guidelinesin order to solve it. After the resolution is written, the committee will vote on it. If your resolution passes, that is a mark of your committee’s ability to work together and compromise well.Awards are also often given out at conferences to top delegates in each committee. These are often delegates who had well-designed position papers, debated effectively, worked well with other members, and took an active role in developing the written resolution. How CanYou Start a Model UN Group at Your School? If your school already has a Model UN group, you can probably join it the way you would join any other school club. If there is no Model UN club at your school, then you can also start your own. We have a guide that gives step-by-step instructions on how to start your own club, and we also have some specific tips for starting a Model UN club below. First, you’ll need a teacher to act as the adviserfor your Model UN club. When you apply to start a Model UN team, your school may assign a teacher, but, if not, consider asking a social studies teacher who likely has a strong background in the issues that Model UN discusses. After you have recruited members and set up meeting times, the next step is to choose which conference(s) to attend. Currently, over 400 conferences take place all over the world. You can search online for conferences, and a list of larger conferences is also available here. For new clubs, you may want to choose a conference that is close to your school in order to make traveling easier and less expensive. It’s possible for a Model UN team to sign up for multipleconferences, butif your team is just starting out, you may want to begin with only one or two conferences a year to make sure members aren't overwhelmed with work. Also, because new teams usually don't get first pick for what country they'd like to represent, if you'd like to represent a larger country like China or the US, you have a better chance of getting your first choice at a smaller conference. Be aware though that representing a larger country often requires more research and preparation. Once you have a conference selected, your team will be assigned at least one country and committee to represent.You can now divide up roles and begin researching. What Are the Benefits of Joining Model UN? Now that you know what Model UN is, what are the benefits of joining it? Model UN can be a great addition to a resume or college application, and I've discussed four of itsmost important benefits below. Benefit #1: Hands-On Experience in Politics, International Relations, and Current Events If you are planning a career in international relations, politics, or you’re simply really interested in these topics, Model UN is one of the best extracurriculars you can join because it gives you hands-on experience in these areas.Most of the time, students interested in these subjectscan only learn about them in class or by reading on their own.While this is a great way to get more information, itusually isn’t a very interactive experience. Model UN involves many of the same activities that actual UN delegates participate in, which is a great way to learn how different countries and committees work together to solve problems.Model UN conferences also focus on current issues, so you will be learning about relevant current events that are likely being discussed and debated around the world. Hands-on experience can makeunderstanding ideas and concepts easier, looks stronger on college applications because it requires more work, and is often more fun to participate in as well. Benefit #2: Improve Public Speaking and Debate Skills During a Model UN conference, you will spend a lot of yourtime giving speeches and debating with other delegates, which can really improve your skills in these areas. Public speaking and debate skills are useful for almost every career, so no matter what kind of job you want in the future, boosting your skills in these areas will likely benefit you down the line. Benefit #3: Learn Teamwork Skills Every step of Model UN requires teamwork, whether it’s dividing up research assignments, writing a position paper, orcreating a speech. At the conference, teamwork becomes even more important because you must work with the other delegates to come up with solutions that everyone is happy with and write a resolution paper together. Model UN delegates often gain experience in conflict resolution, consensus building, and negotiations, which are teamwork experiences many other clubs don’t offer. Strong teamwork skills are very important to colleges because they want to admit students who will work well with their classmates and other students on campus. Having strong teamwork experiences such as the ones you can get through Model UN can help strengthen your college applications. Benefit #4: Possibility of Travel If you participate in Model UN, there is also the possibility of traveling to new cities or even new countries.Model UN conferences are held around the world, and if your team can afford to travel to a foreign conference, you can get the added benefits of exploring a new placeand culture, as well as meeting students from other countries. If you join Model UN, you may get to travel to some exciting places for conferences. Soshould you join Model UN? If you have enough time in your schedule and are at all interested in international relations, politics, debating, or public speaking, then Model UN can be a great extracurricular to get involved in because it includes a lot of hands-on, relevant work and can be a strong addition tocollege applications. If you're still unsure, drop by a meeting at your school to get a sense of what joining the club would be like. Summary Model UN is a club for middle school, high school, or college students whose members simulate UN committees. Model UN members are assigned at least one country and committee. They research the country and the relevant issues to prepare for a conference. At the conference, students representing many countries and issues come together to debate their positions and agree on solutions. Model UN is a great extracurricular for students looking to learn more about politics, current events, or international relations and for students who want to improve their public speaking or debate skills. You can learn more about Model UN here. What's Next? Looking for other after-school activities?

American History Essay Example | Topics and Well Written Essays - 750 words - 3

American History - Essay Example This act of civil disobedience became the spark that ignited the masses during the 1950’s and 1960’s in protesting the racial inequalities. The government, today widely viewed as a body that finds solutions to such social problems, was the entity that created this problem in the first place. The Jim Crow laws that disenfranchised black voters ensured that only white opinions mattered in the political process. Segregation, during the Jim Crow era, was not limited to transportation mediums. In Alabama, hospitals, whether public or private, could not require a white nurse to care for blacks (â€Å"Jim Crow Laws†, 1998). The subject of segregation became a much discussed topic during World War II. The nation that hailed itself as the symbol of freedom sent its young men to fight and die in a war to make the world safe for democracy. An embarrassing aspect of this high idealistic struggle was that U.S. blacks were subjugated within the very armed forces that were supp osed to stand for freedom of all nations. The black soldiers, of course, very much resented this lower class distinction as they bled the same color red as the white soldiers. The heroic actions by many black soldiers during the war began a change of direction in the attitude of whites throughout the country regarding race relations. The U.S. Constitution provided the lawful assurance that non-violent strategies were defensible in court. This allowed for the protests which inevitably led to the awakening to the black plight of many unwary whites who then joined the cause leading to the eradication of racist Jim Crow type laws forever. People, both black and white, were now willing to violate absurd, archaic local segregationist laws because they believed they were abiding and defending a ‘higher law,’ the Constitution. The original objective of the Southern Christian Leadership

The Effects of Tourism on the Small State of Monaco Research Paper

The Effects of Tourism on the Small State of Monaco - Research Paper Example detrimental ecological and environmental effects from tourism has resulted in the development of policies for sustainability in Monaco, termed sustainable tourism . 5 Social and Cultural Effects 6 Tourism has significant effects on the social environment of the area where it is occurring. It separates those who are involved in the tourism industry from those who are not, and limits the choices that the population can make, as any decisions must take into consideration the effect of the decision on tourism . This is particularly true for Monaco, which has focused on tourism since before the Second World War. Now, tourism and banking are the two major sources of income for the state, and any decisions that the state makes need to carefully take into account their effects on the tourism industry. In addition, there are specific effects that the form of tourism in Monaco has on the people and the community. Gambling is often associated with crime and prostitution, even in expensive casin os, such as those in Monaco . 6 Research Design 7 Problem Statement 7 Tourism in Monaco is a booming industry that is the focus of much of the activities of the state for more than 100 years. While there is significant evidence in the literature of the impact that the industry has had on the state as a whole, such as increasing economic output, allowing the state to be self-sustainable, the creation of many jobs, and a high standard of living. There have also been negative effects, such as tourism aiding in the spread of an invasive species, the financial reliance that the state has on tourism, and the potential alienation of citizens that are not part of the tourism industry. There has not been much discussion in the literature about the reaction of citizens to the industry, whether they... The state experiences a Mediterranean climate with hot, dry summers and wet, mild winters. In is two square kilometers in area, making it the second smallest independent state in the world, with only Vatican City being smaller. It is almost entirely urban, with a high standard of living and currently has the longest life expectancy at birth of the independent states. As well as attracting tourists through its gambling facilities, the state is also a major banking centre, and acts as a tax haven with no income tax and low taxes for business. The country is a constitutional monarchy, having a head of state as well as a head of government and a cabinet (Central Intelligence Agency, 2011). The state has little to no natural resources, which limits its ability to develop sustainably (D'Hauteserre, 2005). The rapid growth of tourism worldwide has been a consequence of advances in transportation, with global transportation no longer being a complex venture, as well as being cheaper, safer and more convenient. In addition advances in communication and in technology have played a substantial role as well as other factors, such as the prevalence of people with high disposable incomes that are seeking pleasure, relaxation and comfort (Smith & Eadington, 1992). The first real influx of tourism to Monaco was in 1863 when a performer known as the Magician of Monte Carlo began to manage a new gaming company. This provided most of the revenue for the state until World War II began. Currently the state now hosts millions of visitors a year and has many investors (D'Hauteserre, 2005). The production of a world famous casino during this period was one of the key methods that the state benefited from tourism.
