Students Still Satisfied in 2015 [Infographic]

Many will be shocked to see the results of the National Student Survey 2015. Students paying the higher  £9,000 tuition fees took part for the very first time this year. As a result of this you would expect a significant decline in student satisfaction levels. Yet, the 300,000 students who took part remain just as satisfied with the time they have spent at university as students were last year. The new, higher fees were introduced back in 2012. Because most of the respondents to the survey were final year undergraduates this meant that around two-thirds of them have been paying  £9,000 for tuition. Therefore the survey indicates that the rise in fees has not altered the level of satisfaction among students, considering the same percentage of students were satisfied with higher education in 2015 as they were in 2014. Another shocking revelation which came out of the survey is that the top-scoring universities for satisfaction weren't necessarily the more prestigious Russell Group institutions as you might expect. In fact, more medium-size or campus-based universities came out on top. And this is highly significant! The reason being, tuition fees are set to rise again in 2017-8. The National Student Survey is likely to play a role in which universities will be allowed to raise their fees. Here's something for you to ponder on: Does this mean that some of the less prestigious UK universities will wind up charging more for tuition than esteemed universities?

How to Make Floam

How to Make Floam Floam  is a slimy substance with polystyrene beads in it that kids can mold into shapes. You can sculpt with it or use it to coat other objects. You can store it to reuse it or allow it to dry if you want permanent creations. Its a lot of fun, but not always easy to locate. You might be able to buy it at some stores and online, but you can make a type of Floam yourself. As with slime, its very safe, though anything containing food coloring can stain surfaces. Dont eat Floam. Polystyrene beads simply arent food. How to Make Floam Difficulty: Easy Time Required: This is a quick project: It takes only minutes Supplies 2 tsp. borax1/2 cup water1/4 cup white glue (such as Elmers)1/4 cup waterFood coloringA resealable plastic bag1 1/3 cups polystyrene beads Steps Dissolve 2 teaspoons of  borax completely in 1/2 cup (4 ounces) of water. Two teaspoons of borax will produce a stiff product. If you want more flexible Floam, try 1 teaspoon of borax instead.In a separate container, mix 1/4 cup (2 ounces) of white glue and 1/4 cup of water. Stir in food coloring.Pour the glue solution and the polystyrene beads into a plastic bag. Add the borax solution and knead it until its well mixed. Use 1 tablespoon of the borax solution for a very fluid Floam, 3 tablespoons for average Floam, and the entire amount for stiff Floam.To keep your Floam, store it in a sealed bag in the refrigerator to discourage mold. Otherwise, you can allow it to dry into whatever shape you choose. Tips for Success How it works: The borax reacts to crosslink the polyvinyl acetate molecules in the glue. This forms a flexible polymer.If you use a 4-percent solution of polyvinyl alcohol instead of glue, you will get a more transparent product that will hold shapes better.You can find polystyrene beads at craft stores, usually as fillers for bean bags or dolls. You can grind plastic foam cups using a cheese grater if you like.

Review #3 Essay Example | Topics and Well Written Essays - 250 words

Review #3 - Essay Example The appearance of hand axes is evidenced in the Lower Paleolithic period as used by the Homo erectus. The initial radiation Homo erectus is found to emerge from Africa and Eurasia. The evolution of this species of Homo sapiens dates back to approximately 160,000 years from both Africa and Eurasia. Ultimately, Homo sapiens are described as more civilized humans, with the appearance of bows and arrows being linked to Homo sapiens sapiens in the past 10, 000 years. The five part discussion in this article have an historical significance to the humans as they help in understanding the origin of mankind. From the 5 parts of the article it is possible to ascertain that human beings have through the evolution become wiser, from one ancient period the other. This is crucial to human understanding that every generation that emerges is always at a better intellection capability than the preceding one. Lastly, the entire five parts of the article focuses on the origin of humankind based on many assumptions that do not embrace a religious account of the creation of human beings. The differently can only be seen as an opposed illustration of evolution of human from a primitive ape, which highly differ from religious

Theater Research Paper Example | Topics and Well Written Essays - 3250 words

Theater - Research Paper Example It portrays the writer as one who lived in the small estate outside Moscow and loved travelling while those he created slug in the rural parts of Russia. The play entails a lot of ironies and off stages performances that requires an acute sense of listening and sight to connect. The Seagull is the pioneer among the Chekhov’s four plays, his work are praised for the projection of melodrama intertwined with conventional dramatic topics and techniques that transcends Chekhov’s styles. The Seagull introduces the technique of â€Å"indirect action† a situation in which violent or intensive events in the play are not presented on the stage. Such events occur in the intervals of play as viewed by the audience and involve the inaugurated major changes in both the writing and execution of the play on the stage which is a persistent evolution in the present day play writing (Jae, 2012). Chekhov’s main plays capture little of traditional plot with primary activities of quotidian performed by characters with conversations of illusions of the unseen events which are intermingled with issues of daily affairs and discussions from random observations. Chekhov’s plays are characterized by momentous events which are depicted from the characters’ actions and scripts seen in their effects to each other. These plays often seem to focus more on the characters’ reactions to events than on the main events themselves. His plays are able to analysis and convey the effects of crucial events in the character’s lives more precisely than in other plays. These characteristics and techniques are clearly portrayed in the play The Seagull where highly charged events of drama are traditionally displayed though is not portrayed on the stage. We only see the effects of usual life in the lives of characters and no crises are clearly shown in the usual sense. This is only presented by the precipitating events and the effects of their consequences in

Retaining Top Performing Employees Research Paper

Retaining Top Performing Employees - Research Paper Example According to Sandhiya and Kumar (1778), â€Å"There are many factors which show the importance of the employee retention. They may be the turnover cost which includes hundreds of thousands to the company's expenses. In fact, it is difficult to calculate the turnover cost which includes hiring costs, training costs and productivity loss†. Other than material investment, loss of company’s intellect and information is also another major drawback that an organization has to sustain to when an employee leaves. Sandhiya and Kumar further assert that â€Å"the relationships between the customers and clients are developed in such a way that encourages continued sponsorship and services of the business. When an employee leaves the organization suddenly, the relationships that employee built for the company are suffered and also could lead to loss of contact with potential customer†. Hence, overall business performance is affected due to lack of connecting link between cli ent and organization and also potential risks of losing business may emerge as client may have their loyalty attached to a particular employee instead of an organization. In addition to that, employee turnover has a ripple effect; it has a tendency of affecting current workforce. Withdrawal of one employee can affect motivation level of other team members and in some cases may signal anxiety in employees. Employee retention rates have their contributions to employer’s goodwill which helps in attracting new talent and becoming a preferred employer.

Measuring Public Attitudes to Reality TV | Methodology

Measuring Public Attitudes to Reality TV | Methodology 1. Outline the considerations you would make in deciding between using the Thurstone, Likert or Osgood method. Highlight the particular context and conclude with a clear decision about which of the three methods you would chose. The three social research methods of attitudinal measurement are appropriate for use in this experiment as they all give statistical evidence to support the questions relating to various attitudes taken from a general consensus of people. However, each has its own merits to be considered. The Thurston, Likert and Osgood methods can give a representation of social attitudes toward Big Brother, however, which is the most ideal requires some consideration of their procedural processes. The nature of measurement and descriptive qualities in each method was considered before a test was decided and questionnaire constructed. Thurstone was one of the primary social scaling theorists. He used the average rankings of a set of attitudinal statements based upon a given topic to determine a set of agree/disagree responses. He formulated three different methods that all worked upon a uni-dimensional scale. These were the method of equal-appearing intervals, the method of successive intervals, and the method of paired comparisons (Thurston, 1928). The three methods crucially differed in how the scale values for each item were constituted from their base source. However, in all three cases, the resulting scale was rated the same way by respondents. This labour-some method did not take into account any indifference towards the statements or the degree to which negative and positive attitudes could vary. In questionnaire format it relies upon closed questions to gain its data and measure attitude. Furthermore, it indicates a mean average as its descriptive data between that of agreeing and disagreeing in each state ment category,which does not capture the nature of the deviation or sway of general trends in attitude. Neither does it allow for a consideration of word connotation within the statements. Due to these considerations this method of measuring attitude was rejected for this experiment. The Likert technique was developed after the Thurstone scale. With this method to social research a set of attitudinal statements were also presented to subjects. Subjects were asked to express agreement or disagreement according to a five point or seven point scale measuring the variance of attitude towards the statements (Likert, 1932). Each degree of agreement or disagreement was given a numerical value from one to five / seven rather than being defined as a closed agree or disagree category. A total numerical value was then to be calculated from the total number of responses. This method is suited to our experiment as it can be applied to established attitudinal theories such as Ajzen’s Theory of planned behaviour as a way of drawing out not only attitude but intention and concepts that help shape our attitudes. Essentially, the Likert method can be broken down into segments pertaining to the theory of planned behaviour to reveal a more sophisticated set of results that in dicate a fuller relationhip than that of the Thurstone method. However, one more method that relates to the Likert method should be considered before moving on. The Osgood method was developed in conjunction with the Likert technique. Using the scale as the basis for the measurement of attitude, Osgood concerned himself with the significance of meaning, and in particular connotation of words. Typically subjects would be given a word or concept, such as race, and would subsequently be presented with an array of adjectives in which to describe that word / concept (Osgood, 1957). The adjectives would then be represented at either end of a five point / seven-point scale similar to the likert scale. Due to this, Osgood was able to contrive a map or model of peoples connotations for given concepts from which attitudes could be understood. However, there are problems for using this method for our experiment. Firstly, there is the problem that this map depends entirely on the presumption that all adjectives mean the same to everyone. Because of this, the method itself becomes contradictory as it begins from the general assumption that peoples connot ations for certain cocepts differ. However, it also depends upon the assumption that, for certain words at least, they do not differ. And secondly, there is nothing in this test that attempts to negate the onset of socially desired responses from participants. For this reason, the Osgood test for connotational attitude was dropped as the method for this experiment in place of the five category Likert test. 2. Provide a detailed description of the steps you would need to take at each stage of scale construction, using your chosen method. In the first stage of developing the Likert method for this experiment, relevant attitudinal questions would have to be established and drawn up. Based upon the preliminary research into certain perceived attitudes towards Big Brother, these questions should be drawn up and applied to a five point scale ranging from strong agreement through to strong disagreement. These should be comprised into sets of varying attitudinal question types that relate to the different categories apparent in the Theory of Planned behaviour. These sets should consist of questions relating to social norms, attitudes and perceived behavioural control (Ajzen, 1991). For example, the first two sets of questions should be taken into account, that is the subjective norm and the attitude, and categorised as one set. For example, based upon the measurement method of the likert five category system, typical questions relating to these sets could be ‘do you think Big Brother is valid?’ and ‘do yo ur friends tink big brother is valid?’. These provide us with indicators of varying attitudes from which behaviour could be measured as an outcome. For instance, questions then asking ‘would you watch Big Brother?’ or ‘is it your intention to watch Big Brother?‘ would give us an indication of the strength and nature of the forces creating the attitudes towards Big Brother. A third set of questions relating to the perceived behavioural control could then tell us of how people perceive the viewing of Big Brother and how that affects their attitudes and intentions towards watching the show. According to the theory of planned behaviour, these three attitudinal variables inform the intention from which behaviours can be understood (Ajzen, 1988, 1991). By taking the findings of this questionnaire through the method of the Likert scale, we are providing ourselves with a technique which can register, incorporate and analyse the findings of a limitless amount of subjects and find trends in the different ways that people have formed attitudes towards Big Brother. It is with the Likert model that an attitudinal questionnaire based upon the theory of planned behaviour was constructed to answer the main question put forward by this experiment. An example of the three sets of questions based primarily upon the theory of planned behaviour and developed at this stage are as follows: I like to Watch Big Brother? Strongly Agree / Agree / Indifferent-Unsure-Never Seen It / Disagree / Strongly Disagree. My Friends Think People Should Watch Big Brother? Strongly Agree / Agree / Indifferent-Unsure-Never Seen It / Disagree / Strongly Disagree. It is Morally Acceptable to Watch Big Brother? Strongly Agree / Agree / Indifferent-Unsure-Never Seen It / Disagree / Strongly Disagree. The next stage should be firstly concerned with eliminating ambiguous or leading questions such as those involving the terms ‘hate‘ and ‘love‘ or ‘nice‘ and ’kind of’ etc. This can be done where confusion is noticeable manually or where indicated on the results of pilot studies. This stage should then be concerned with content validity. This can also be done via a pilot test; by using the questionnaire to test a group whose attitudes are well established. For example, you would expect members of a Big Brother fan club or groups that promote Big Brother to score positively on attitudinal questions relating to Big Brother. However, if the results show that they did not score positively then this can be taken as an indication that there is something wrong with the questionnaire. Conversely, if they do score positively then the pilot test can be deemed valid. Alternatively, a professional or expert in matters of attitudinal tests could be consultd for clarity. After these questions have been arranged according to category and the pilot test and/or expert has given sufficient content validity, a sample group should be targeted and asked to participate. On defining that target group, an introduction giving them the required and ethical briefing should be performed, and on their completion a debriefing and contact address should be disclosed. On retrieval of the results, an appropriate measurement should be carried out to establish the descriptive and inferential statistics of the likert test. The procedure for the Likert does not involve mean averages as these merely convolute the sway of the attitudinal range. Rather, median and modes are better equipped to give descriptive data as the significant range is concerned with general trends rather than precise measures. Bibliography Ajzen., I.

Marxism Essay -- essays research papers

In this paper, I am going to explore the differences between communism and socialism and how different the thoughts and opinions of these two ways of life are from the current western views on religion and God. To explain about the differences between socialism/communism and western thoughts on religion I will explore the writings of Karl Marx and Frederick Engels. They are founders and writers of a lot of the socialist and communist thoughts on religion and God. In our western society when we discuss God and religion, people for the most part are going to lean one way or another when it comes to their beliefs on religion. If you are from the western part of globe like myself the views and thoughts hinge on the belief of God as a superior being, a perfect one, one who controls everything that happens. The other side of the coin in western culture would be the atheist who does not believe in God at all. There are many other views about God and Religion that differ greatly from the vi ews that are held throughout the western regions of the world. In a lot of the Eastern countries of the world the teaching of the Socialist and Communist parties that rule these areas of the world has influenced the views that have been passed down and taught through out the years. Communism and Socialism do not believe in the theory that there is one perfect God and that you can only receive salvation through him. In the western religions of Judaism, Christianity and Islam, God is the one and only Supreme Being, the Creator of everything. Nothing exists in the world to these religions unless God had created it. God is the omnipotent, omniscient, omnipresent, all good and eternal to salvation. God created the world and all its components for a purpose. God created human beings to know, to love, to honor, to serve and to obey Him. God is to be thought of in masculine terms, even though God is a pure spirit and has no material or bodily parts. Humans will be judged after death as to how well they have fulfilled God's plan for them. Those who have failed, the sinners, will be punished for eternity. Those who have succeeded will be rewarded for eternity. The exact nature of the reward or punishment is hotly disputed, but all seem to agree that those who are rewarded will be in God's presence and those who are punished will not. There are many arguments from people who do not believe... ...gard to the next world. Religion is the opium of the people, that is, it acts as a kind of painkiller. Religion makes bearable the unbearable, such as: poverty, hunger, inequality and repression that happen in the world.   Ã‚  Ã‚  Ã‚  Ã‚  The Christian religion means salvation to some and to others it is only something that only resides in the thoughts of the people of that society. A Marxist would tell you that true salvation could only be achieved here on earth by working. Salvation is something that all would hope would be in the future for themselves. In this paper we have examined two differing opinions on how salvation can be achieved one was through religion and the other was the socialist way of life. The argument between societies about religion will not be settled here on earth. Who is right and who is wrong in the argument about religion? Is religion just a figment of our imagination, is it something humans made up to make us feel good about the future and our salvation. Or are the Marxists wrong, could religion be everything it is meant to be in the Christian religion. Could religion be the real salvation? These are great questions to ponder and talk about.

P&G Strategy

Executive Summary Competitive analysis of P&G often focuses on hard outcomes like market share, gross margin, and number of patent applications but misses some under-appreciated but nevertheless critical strategies that drive P&G's business. The least understood and most powerful P strategy Is leveraging Its scale. Least understood because It Is hard to measure; most powerful because It touches everything the company does.P& G has four separate identifiable scale leveraging strategies: 1 a retail trade strategy a top down Corporate vs.. Division/brand funding strategy a consumer cohort strategy systemic strategies Scale Is becoming Increasingly important, particularly as retailers globalize and continue to drive out supply chain costs. We bring Industry-leading supply chain management and the Intellectual capital of our people to retail partnerships. We have higher-than-average market shares at our top global retailers.As big customers grow, P's overall market share grows. Leverages Its Scale In Ways That Competitors Don't Fully Appreciate Leveraging scale with the retail trade These are programs that have a high perceived value to the retailer and reinforce P's competitive advantages. Of course, these programs are most aggressively sold to the more enlightened retailers who are gaining share in the marketplace. In fact, gaining share with growing retailers is another major P&G strategy. Everyone recognizes that retailers are becoming more and more powerful, demanding more price concessions from manufacturers while themselves marketing private brands of higher and higher value to consumers. Most manufacturers respond by dumping cash into the retailer's wallet. P responds by leveraging its scale. P is investing tens of millions of dollars in Supply Chain efficiencies to come the low-cost distributor, developing innovative distribution concepts and then â€Å"marketing† their advantages to retailers with sophisticated Activity Based Costing software tools. In addition, high volume from multiple categories permits P account handlers at all levels to offer retail customers benefits such as: Account- specific consumer research Major theme events with genuine substance which make the retailer look good to their consumers (e. G. , the Women's Health Initiative at Wall*Mart) Multi-category consumer studies (e. G. Mothering) Software analytics We see retail consolidation as an opportunity that P&G is uniquely capable of leveraging.

buy custom The Sun Recorded Through History essay

buy custom The Sun Recorded Through History essay The heat energy is supplied to a fluid, which is heated until it vaporizes; the vapor is then compressed at high pressure, and released at high pressure to give motion to a gas turbine that is coupled to a generator. When the turbine is set into motion by pressurized gas or water vapor it rotates the shaft connected to the generator, which in turn rotates the shaft connected to the coil of the generator giving motion to the coil of the generator. A generator is a machine or a device, which converts mechanical energy to electricity. The mechanical energy that is converted to electrical energy can be obtained from nuclear and chemical energy found in various types of fuel, it can also be obtained from sources such as falling water or wind. This mechanical energy can be supplied to the generator using water or wind turbines, electric motors, gas combustion turbines, internal combustion engines and steam engines. The working principle of a generator is based on the electromagnetic induction phenomenon. The generator has a conductor that is placed between two magnets; the movement of the conductor relative to the magnetic field created by the two magnets induces a voltage in the conductor. If there is an external circuit connected to the conductor, the voltage induced in the conductor would create a current in the circuit, and the energy in this circuit can be delivered to a load. To obtain a larger current from the conductor, a large force must be applied to rotate the conductor and keep it in motion. Most modern generators have self excited fields; this means that the current in the field coils comes from the additional exciting winding found in the armature. Before the voltage is fed in the field coils, it is rectified by passing it through a diode bridge, then passes through a regulator. A portion of current that is generated by the generator flows into the field coil generating a magnetic field. However, before the generator is started the magnetic field is generated using the residual magnetism in the cores of the magnets or a current from a battery. Biofuels, which include ethanol or biodiesel, are known as liquid sunlight. Ethanol is produced using plants to convert solar energy into a liquid that is used as a source of energy in transportation system. Plants capture the suns energy through the process of photosynthesis, and then transform the energy to cellulose, sugars and starches (Nelson par 8). Ethanol is later manufactured using various industrial processes by combining water with plant material with an addition of energy; the processes produce ethanol and byproducts, which include polluted water. The resultant product, which is ethanol, is then used in transportation systems. The current processes of producing ethanol from sunlight are regarded as involving and costly. The required raw materials is from biomass, mostly from sugarcane and corn among other energy crops, and this energy crops must be grown extensively for large-scale production; this has a huge economic implication and creates competition for land with the food crops. Technology of converting sunlight into fuel has taken another route in order to solve the problem of competition for land with for food crops, and reduce the cost of production. The latest technology uses bacterium that is genetically modified to convert sunlight, carbon dioxide and water to fuel; this technology is expected to produce more fuel than that produced by ethanol (Nelson par16). When 1litre of ethanol is burnt, it produces 23.5 million joules. Rivers are natural systems that provide falling water or flowing water that sets a generator into motion. The falling or flowing water is because of the water cycle caused by sunlight, when the sunlight heats the earth surface, it causes evaporation of water from the earth surface, this water in the form of vapor rises up the earth surface, and when it reaches the high regions above the earth surface, it condenses, and later falls as rain. The rain water percolates through the soil and rocks, and collects in channels forming rivers. The water in the rivers flows and if a generator is placed in its path, it gives the generator a motion, if the water in the river encounters a steep rock it creates a waterfall, and when a generator is placed below the waterfall, the falling water gives the generator a motion. This energy from falling or flowing water gives motion to the generator, and it is considered ultimately from the sun because without the sun, the water on the earth surface would not evaporate, condense and fall as rain that later collects to form rivers that flow. The ice that forms on top of mountains also melts to form water that flows down the mountain to join the rivers that flows giving motion to the generator; without sunlight, the ice on top of mountains would not melt to water, and there could be no water flowing in rivers to give motion to the generator. The amount of energy that reaches the top atmosphere is 1,360 watts per square meter, and the amount arriving at the earth is 340 watt per every square meter. This is only one quarter of the solar irradiance; it is also the average amount of energy that reaches an individuals roof per square meter. However, the exact amount reaching ones roof in a day depends on the location of the house on the earth surface, the time of the year and time of the day. When one wants to use the 340 watt energy per square meter and the daily consumption of 14,400 watts per day, then a 26 square solar panel is required, which cost almost $16,000, and since sunshine is not consistent an inverter is required, which increases the cost of installation further. Looking at the annual electricity bill, it amounts to $91, it is better to use electricity from the main than pay for all that money for installation. The payback period for such an energy system is long, and considering the low efficiency of solar pow er systems, it is not worthy investing in them; this is why many people shy from using these systems. Solar cells are used in satellites, calculator and solar power production systems; they are also referred to as photovoltaic cells. Photovoltaic cells are constructed using semiconductor materials such as silicon; these cells convert sunlight straight into electricity. When the suns light strikes the solar cell, part of it is absorbed in the semiconductor material, and knocks the electros in the structure making them free to flow. The electric field in the semiconductor material then forces the free electrons to flow in a particular direction, and as the electrons flow they create an electric current. Silicon, a material used to make the solar cell havespecial properties, especially when it is in crystalline form, it has 14 electrons in its three shells, the first and second shells have two and eight electrons respectively. The third hell has only four electrons, this means that this level is half full, therefore, it will always seek for how to fill the remaining space for four electrons. Silicon will be forced to share electrons with the atoms surrounding it, forming a pure crystalline structure; this structure does not readily onduct electricity because it has no free electrons (Martnez 321). Therefore, the structure is mixed with atoms with free electrons such as phosphorus to make it conduct electricity. When the sunlight strikes this structure, it forces the electrons to break free, and each electron leaves a hole behind and looks for another electron to occupy; this causes the electrons to move randomly in the crystalline lattice, and as they move, the carry current. The performance of a PV cell depends on conditions such as the type of PV cells, solar spectral, angle of incidence, solar irradiance and the temperature. Approximately 90% of solar panels used today are made of crystalline silicon; they convert 15-20% of the sunlight to electricity (Martnez 346). There are solar cells that have a thin film of crystalline silicon, this type of solar cells converts 4-10% of sunlight reaching it. The solar cell produces a DC current, which can be used to power DC devices, however, for systems that are designed to power AC machines or appliances, an inverter is included to change the DC current to AC. A refrigerator is a system that transfers heat from a region of low-energy to a region of high-energy reservoir. This system consists of the following components, the cooling coil, evaporator, condenser, compressor, condenser pump, cooling tower, cooling tower fan. The refrigerant absorbs heat from the chiller or freezer chamber, then moves evaporates in the evaporator and sucked by the compressor and discharged outside the refrigerator. The air condition uses the working principle similar to that of a refrigerator, however, the difference is that the air conditioner cools a bigger space when it is compared to the refrigerator; it can cool an entire room, while a refrigerator cools only a chiller or freezer. The air conditioner consists of a compressor, condenser and evaporator; the working fluid goes through the compressor at while it is cool and at a low pressure, it is then compressed and passed to the condenser at a high pressure, then passed to the evaporator where it changes from liquid to vapor, as it cools the room (OECD Nuclear Energy Agency 285). The vapor is then cooled in the condenser and sacked back into the compressor, and the cycle repeats itself. The refrigerator can be used as an air conditioner if it is improvised by placing the evaporator in an open place that needs to be cooled. This is because their mode of operation is the same. The only difference is the size of the area they are cooling. The conversion of heat energy to electricity has been tried using several physical phenomena, however, the direct conversion has not been fully achieved; this is because of the temperature levels between the processes of operation. The Carnot efficiency is an efficiency that operates within the same limits of temperature between the source and the sink. Many systems converting heat energy to electricity have tried operating within the same limit of temperature, but the result is only a small percentage of the ideal efficiency, which is the Carnot efficiency (Chen par 12). This is because of the inefficiencies of the converting system, an example of such systems is a system that converts heat energy to electricity using thermocouple; this system produces electromotive force when one of the dissimilar conductor gains heat while the other remains cold. The conductors of the thermocouple are metals that are inefficient in converting heat to electricity; the metals are good electricity co nductors, and at the same time good thermal conductors, this makes the hot conductor lose the heat it has gained to the cold metal conductor, thus lowering its temperature. Such a system cannot achieve Carnot efficiency because the Carnot cycle assumes that all the heat gained from the source is converted to electricity without loses. The Carnot cycle efficiency is computed using the formula %u1DAF = 1 T2/T1 where T2 is the temperature of the conductor and T1 is the temperature of the source of heat (Chen par 15). This is the best efficiency one can hope for when converting heat energy to electricity. The earth is an engine that is controlled by the heat from the sun, the goes round the sun and because of its spherical shape it receives varying heat from the sun, with the tropics receiving more heat than the poles. This creates an imbalance in the available heat on the earth surface, and to balance the heat, energy is transferred from places with low latitudes to those of high latitude. The imbalance in the earth heat is also brought about by the rotation of the earth around the sun, which creates days and nights; places that experience day and night receive more heat energy from the sun at a given when compared to those experiencing night. The imbalance of heat on the earth which caused by uneven heating of the earth by the sun determines the earths vegetation cover, ice, precipitation and temperature. The difference in temperatures controls the movement of air from one region to another; this movement involves cold and warm air, and depending on the kind of air present in a region, the region is referred to as either warm or cold. The difference in precipitation and vegetation cover is also caused by uneven heat of the earth by the sun, when the earth is heated the water on the earth surface rises in form of vapor and later condenses and falls in form of precipitation, and the precipitation gives vegetation enough water required for its growth. This explains why the tropics receive much rain and have more vegetation cover than the poles. The uneven heating also controls the amount ice in different regions, with regions receiving less heat from the sun having more ice than those receiving more heat. The above described aspects also affect the population of people and animals in various regions around the earth; areas with high precipitation and vegetation are mostly inhabited by people and animals, while those with less vegetation, precipitation or covered with ice are avoided by human being and most animals. All this is controlled by the heat from the sun. Nuclear fission is a process where elements with large nucleus are split into small nuclei, nuclear power plants and industries that manufacturing nuclear weapons use this process. Elements that are used in this process include plutonium-239, Uranium-233 and Uranium-235, when these elements are struck by a neutron moving at a slow speed, they undergo fission. An example of such a reaction process is The result of the fission process is elements of smaller nuclei and a neutron, the neutron can be used to split another Uranium-235. The process goes on and on leading to a chain of reactions, however, the reaction should be controlled, else the chain reactions would lead to an explosion. The moderated reaction can be used in a nuclear reactor as a source of fuel; it is used together with control rods to control the process by absorbing excess neutrons. Elements are identified using the nuclei of the parent atoms, for instance, carbon is an element with 6 protons in its nucleus while Uranium is an elemennt with 92 protons in the nucleus. Uranium is the heaviest element; heavy elements are formed from light elements through the process of fusion. The simplest reaction being hydrogen and hydrogen, and later, the fusion reactions merge to form heavier elements. During the formation of the universe, there were high temperatures and density known as big bang, and only the elements with heavy nucleus were formed, this includes, hydrogen, beryllium, helium and lithium. Heavier elements such as Uranium were created during a nuclear reaction that took place in the stars, as well as during huge stellar explosions referred to as supernovas (MacDonald 256). The sun and other stars, and planets such Earth had other elements apart from hydrogen and helium, and these elements, which included Uranium formed after the explosion of the 1st generation of enormous stars known as supernovas (OECD Nuclear Energy Agency 357). Uranium was first discovered on the planet Uranus, and at first it was named Uranus by Martin Klaproth. It is found in pitchblende ore, which is an ore of zinc and iron, however, it can also be found in coffinite, uranophane, carnotite and uraninite minerals. Uranium is considered as a solar power, this is because its formations originated from the formation of energy emitted by the Sun. The solar power was formed from the fusion of hydrogen atoms to form helium atom, the helium atom later combined with other hydrogen atoms to form heavier atoms. The heavier atoms such as Uranium were formed through the fusion of atoms that were lighter that themselves; this shows that power that comes from Uranium is actually solar power because without the initial reaction to form solar power, then the other reactions that led to the formation of Uranium could not have happened. Many scientists worked hard to discover the source of sunshine, and in 1904, Ernest Rutherford discovered that the sunshine was emanating from the emission of alpha particles by radioactive substances. This discovery implied that nuclear energy was the source of sunshine; however, more research proved that the sun did not have much radioactive material, and instead, the sun contained more hydrogen gas. Scientists also discovered that the amount of energy generated by a star does not vary with temperature, but it depended on the interior temperatures of the star (MacDonald 167). These discoveries helped them come closer to the answer, later Aston discovered something that rested many scientists; he discovered that hydrogen nuclei was heavier than helium nucleus, a concept that was used by Eddington to conclude that the sunshine was because of the conversion of hydrogen atoms to helium. This process was known as fusion, and the energy produced from this process depends on the mass of t he atoms, this relation was derived from Einsteins energy equation; E =mc2. The process of fusion could make the sunshine for approximately 100 billion years. 41H 4He + 2e+ + 2+ energy, This process of energy production utilized by the earth has been a dream of mankind to solve the nagging problem of energy around the world. Scientists and researchers have been working hard to achieve this process that produces abundance of energy, they have the equation that result in the large amount of energy, which is the fusion of 4 atoms of hydrogen to form one atom of helium, two positrons, two electrons and energy. However, they realized that hydrogen atoms are positive particles; this means that they repel each other, and bringing them together is difficult. According to Bahcall, it was realized that stars that were heavier than the sun fused the hydrogen atoms using carbon as a catalyst, however, the energy produced from this reaction was relatively low. Scientists have also thought of the stellar evolution theory, which implies that the sun is heated at very high temperatures causing the nuclear fusion of hydrogen atoms to fuse through the gravitational energy emanating from the contraction of the solar mass from its initial large gas cloud. This has given the scientist and researchers of the required conditions for the hydrogen atoms to fuse, however, there is still a struggle to find out the exact conditions for the fusion to take place, and how the conditions can be made possible for the fusion of hydrogen on earth without causing destruction. All energy used on the earth comes from the solar energy; this can either be direct or indirect. Looking at photovoltaic and solar thermal energy used on the earth, they directly comes from the sun, but utilized in the form of electricity and thermal energy respectively. These two forms of solar energy are harnessed directly from the sun. Another form of energy that comes from the sun but indirectly is wind. The sun heats the earth unevenly, and this causes imbalance of heat on the earth surface; the regions that experience more heat have warm air at the surface of the earth, while those that experience less heat have cool air at the surface of the earth (MacDonald 134). Following this imbalance, the warm air will tend to move from a region of high pressure to a region of low pressure, and the vice versa happens to the cool air. This continuous movement of air on the earth surface is wind, and this wind can drive a wind turbine which is used to produce electricity, run wind pumps or wind mills. Hydropower is also derived from the sun, and in this case, the sun heats the earth surface, and the water on the earth surface vaporizes and rises above the ground. As it moves up the sky, it reaches condensation where it forms clouds that later falls as rain. The rain water percolates through the soil and rocks to form rivers, the water in rivers can be utilized to produce energy using either the flowing water or waterfalls along the river channel. Bio-fuels also come from the sun. The sun is used in the process of photosynthesis to produce sugars that are stored in the plant in the form of starch and forms of sugars. The starch and other forms of sugars are extracted from the plant and used in the production of ethanol as a bio-fuel. Another case of bio-fuel production using sunlight uses bacteria that have been modified to utilize sunlight, carbon dioxide and water to form nuclear bio-fuel. Nuclear energy also emanates from solar energy in the sense that, Uranium, an element that is mostly used in energy production using the process of fission, was formed from the reactions that resulted to solar energy. The fusion of hydrogen atoms to form helium atom resulted in the sunshine, and the fusion of the resultant atoms led to atoms with larger nuclei, and Uranium being the heaviest element, it resulted from the fusion of lighter atoms. Fossil fuels are fuels extracted below the earth surface, and they were formed by the accumulation of dead animals and plants. The dead plants contained sugars that were stored after the process of photosynthesis that was initiated by the sun, and the animals ate plants which derived their food from the process of photosynthesis. Therefore, it is only sensible to say that fossil fuels and other sources of energy originated from solar power. Buy custom The Sun Recorded Through History essay

Soft parts consider the contribution of employees and the relations that they have with their employer. On the other hand, hard policies are more focused on physical assets which are used for production of goods and services (Paley 19). This paper will compare and contrast TQM policies a dopted by Toyota Motor Company and Emirates Airlines. Brief history of the Two Companies Both Toyota and Emirates Airlines are more or less in the same industry; transport industry. Emirates Airline is an international airline company that is spreading to various countries. Currently, it has over 100 destinations. It is the major airline in Middle East and the national airline for Dubai, Unites Arabs emirates. It is a sub-subsidiary of Dubai Investment Company, through The Emirates Group. The company was incorporated in the year 1985 as an international flight company and made the first flight to Dubai-Karachi on 25 October 1985. It was incorporated with the assistance of the government of Dubais royal family but the intervention of the government was limited. Toyota is a multinational company found in Japan and it is the leading automobile car makers and seller in the world. It was incorporated in 1937; its founder is Kiichiro Toyoda. According to fortune global survey 500 of 2008, it was the fifth largest company in the world. The company is structured in a no extra ordinary way and has departments like any other multinationals in the world; however the achievement of the company has made it different in performance a thing that proves that something extra happens. In 2008, it was able to surpass General motor company as the world largest automobile seller in the world. What has made the company go this far? The answer is in the quality of its management and the interaction of brand as well the loyalty that it derives from its customers. The number of employees in the company stands at 320,590 distributed in different parts of the world (Black 20).Advertising Looking for critical writing on business economics?

One of the most recent is low c ost services. On the other hard, due to globalization, there has been an influx of international airline companies fighting for the same market. In the efforts of ensuring that the company has remained competitive, it has embarked on massive capital investments. By the year 1987, the company had expanded its destinations to reach eleven in total. It is one of the few start ups that recorded a break even at the first year of service. The earlier airline that operated in the area was Gulf airline; the airline was affected by the Gulf war and Emirate airline so enjoyed the benefit of all this. Being in the plane industry, the company has increased its number of planes and the sizes of the planes; those planes that carry passengers have been refurbished and made to look more modern. In the efforts of surviving low cost competition, the company has made large planes which are used to ferry a large portion of people; this helps in enjoying economies of scale and thus the company can opera te as a low cost. The company has embarked on massive research to ensure that it knows the expectations of its customers and align its service to the needs. It is opening up virgin areas with its operations and collaborations with airlines of other nations. Toyota Company has embarked on resource development especially in technology development. The technology has ensured that the company produces goods which are sensitive to the need of modern motor industry. The company produces one of the most efficient automobiles. The vehicles are also comfortable to compete with companies like Mercedes, BMW, and Fords among others. In the various countries, it has embarked on making warehouses and garages which handle their products in a professional manner (Hino 12). Soft TQMs Soft policies consider human resources of a company. It aims at empowering them conduct their business with efficiency and become more productive. Emirates Airlines has been increasing its employee base. It ensures that it trains its employees to make their services better. This is on current trends in business world and the changes that the industry is going through.Advertising We will write a custom critical writing sample on Comparing a TQM Implementation in Toyota Motor Company and Emirates Airlines specifically for you for only $16.05 $11/page Learn More In the fiscal year that ended on March 2010, the company had employed a total of 36,652 employees all over the continent. The performance of the company has been on a gradual increase; in the year 2009/ 2010, the passengers that used the online were 27.4 million, up from 22.7 million reported in 2008–09, the load cargo in the same period increased by 12.2% to 1,580,000 tons up from 2008–09: 1,408,000 tons. Toyota Company has embarked on international fetching of employees. It employs from all over the world and maintains the team through appropriate appraisal and reward system. Graduates are integrated into the system by a graduate trainee procedure. This is where graduates undergo two year training in Toyota College before they are integrated in the system. When they get into the system, they continue with further on job training and only given targets after the trainers are aware that they can perform effectively. In making decisions, the company engages all staffs. This is where they give their field experiences and recommendations on varying issues (OConnor 44-56). Conclusion Total quality management (TQM) consists of competitive moves and business approaches aimed at producing successful performance; it is management’s â€Å"game plan† for running the business, strengthening a firm’s competitive position, satisfying the customers, the stakeholders, share holders, and the staffs. It seeks to develop the way into which all those that are a party to the business get satisfied. It aims at going a step further and satisfying the customers beyond their expectat ions. There is a lot of focus on the customer; the customer is the greatest asset that an organization can have. To get customers’ loyalty is every business dream and target. Comparing the Toyota and Emirates strategies, it is clear that both of them have adopted a TQM system which is acting to their advantage. They are both enjoying benefits brought about by TQM, which include efficiency in their processes, increased customer satisfaction, competitiveness, and customer satisfaction. Black, Richard.

US Population Growth and its demands on the enviroment, economy and Research Paper

US Population Growth and its demands on the enviroment, economy and national healthcare - Research Paper Example Background The population growth of the United States is ever increasing by about 3 million people per year (Hinde, 1998). Indeed, the overpopulation issue does not exist in the vacuum. The main reason for overpopulation is not because people do not know the main ideas on birth control processes; however, it is due to the immigration of people from other foreign countries (Alejandro & Rumbaut, 1990). In fact, almost 50 percent of the United States population is due to immigration. Worldwide, the main reaction to carrying capacity setbacks would be to migrate to regions where the carrying capacity does not seem to be pushed beyond the maximum level, or it is perceived to provide opportunities. In most cases, much of the United States’ immigration is fueled by this conception, but the immigrants tend to forget that the United States does not possess endless resources. Such wrong perceptions of immigrants do not only cause injustices to the carrying capacity of the many states in the country, but also many other overpopulation components, including environmental damage, social disruption, and even unemployment (Regoeczi, 2002). Demands on the environment Perhaps, the main devastating demands of overpopulation could be seen in the United States’ environs. ... le that the Americans keep on producing a lot of air pollutants that perhaps one day could become hazardous and even get to other regions in the world. Apart from pollution, there exist reasons for concerns regarding the farmland, wildlife, and forestry. It is because of overpopulation that United States has lost a lot of its wetlands, old-growth forests, and on a routine basis go on loosing many miles of land to developments. While a lot of factors such as forests, pollutants, energy, etc. could be those chosen to demonstrate the limitations of overpopulation on the carrying, reflection of striking example is water. Indeed, many areas within the United States, be it the central, west, and even southwest states, mostly those experiencing the rapid growth in population are inflicted either with shortages of water or contaminated water due to pollution. The demand on resources that lead to damages of forestry has caused many states in the United States face limited rainfall. Other natu rally occurring water sources have also been limited resulting in serious depletion and even pollution of the ground water. Clean water is essential to the people of the United States. Carrying capacity of such limited water areas that extend many states is really a threat to the human life. It is notable that, the outcomes of overpopulation demands on the environment are negative. Resources get depleted that the environment becomes disregarded to a certain point that, many regions in the United States lose most of their capacity to support a dense population. Whenever the carrying capacity becomes exceeded, the damage to the environment is normally very severe that the carrying capacity of population for upcoming generations is highly reduced.

Do you think that theories of authorship are incompatible with the Essay

Do you think that theories of authorship are incompatible with the industrial context of film production - Essay Example The auteur theory is one of the most important theories of authorship. The term, politque des auteurs was coined by Francois Truffaut, who realized that American Directors often worked within strictly circumscribed parameters in reference to the kinds of films and the scripts they could direct, since these were often predetermined and allowed the directors little room to experiment with their own ideas (Keller 1930). The notion of the Director being the true author of a film first emerged through the views of Andrew Sarris on the distinctive nature of a particular director’s work. According to Sarris, Hitchcock was â€Å"great† and Welles was classed as â€Å"brilliant†, based on the view that over the course of preparation of several films, a director may reveal certain recurring characteristics of styles or themes, which are like his or her personal signature or stamp upon the film, identifying it unmistakably as their product (Sarris, 1979:650-665), irrespective of the collective nature of film production. It may be argued that American cinema in earlier decades was circumscribed by the industrial context of production and the concentration of power in the hands of studio top executives. The power wielded by the writers and directors of the film was considerably less than that wielded by studio heads and their creative control over the film much lower. Yet, despite these restrictions, some directors such as Hitchcock were able to achieve a personal style that was uniquely their own. In particular, where some directors such as Orson Welles and Jean Luc Godard are concerned, some recurring themes may occur in all their works, or their work may demonstrate a particular worldview or personal vision that becomes evident through their work. They bear the unmistakable personal imprint of the author, despite the plethora of external market and commodity pressures that may fashion the final products. For example, in the works of Godard, the
