Shila Gonsalves Essays (458 words) - Asian People, Shila Amzah

Shila Gonsalves Professor: Friars 03/14/2016 The Story behind the Story" As sit here with my yearbook going through all of the pages and remembering all the fun and ugly times I've had, I am grateful to say I have experienced high school. High school was a love and hate relationship but I still had my fear share of fun. High school was place for us to learn somewhat of who are and our goals in life. Some people in my situation would be very unhappy in high school since I was on my way to finishing up high school in my country. I migrated from Guyana, South America when I was fifteen years of age. And at first I was very sad that I had left my friends behind to come to this big gigantic country USA and make new friends which I struggled with and mostly to start high school as a sophomore. It was a struggle because I felt I knew all the stuff I was being thought but anyways I still enjoyed my teachers they respected that I was from the other part of the world. But making friends was very hard for me I did not know what it was like to be a part of groups in the lunchrooms or after school. But I found my self in an art (ceramics) program that it allowed me to meet and mingle with people similar to me. I also joined the culinary team. I meet a lot of people who were impressed with my work and actually acknowledged that I existed. As I turn the pages I could see my self in two of the pages shockingly, a picture of Shila Gonsalves? Well I have to say I was a very well know cook at my school. Joining the culinary team was one of two greatest decisions I have made in high school. I was so happy to see my self-causing a barbeque fire at the football game fundraiser and everyone was just standing there enjoying my food and having fun with my tricks. This picture I was so surprised to see because I had no idea they took this. My team and I were well known for our cook offs, bake offs and most importantly cooking for our teachers monthly, providing t hem with a lunch once a month. My second picture I was being awarded a certificate for making the best ceramic pieces in Hudson County. These moments were very special to me because I thought I would have never fit in and be a part of my school. But I am grateful for every moment I had in high school, bad or good it made into the person I am today; a confident young lady.

Assael’s Matrix Essays

Assael’s Matrix Essays Assael’s Matrix Paper Assael’s Matrix Paper Assael’s Matrix Assael distinguished four types of consumer buying behaviour based on the degree of buyer involvement and the degree of differences among brands. The four types are named in the following table and described in the following paragraphs. TABLE 20: Four types of buying behaviour: Level of Significances Between |High Involvement |Low Involvement | |Brands | | | |Significant |Complex Buying Behaviour |Variety-seeking Buying Behaviour | |Few |Dissonance-reducing Buying Behaviour |Habitual Buying Behaviour | 1. Complex Buying Behaviour: Consumers go through complex buying behaviour when they are highly involved in a purchase and aware of significant differences among brands. Consumers are highly involved when the product is expensive, bought infrequently, risky and highly self-expressive. Typically the consumer does not know much about the product category and has much to learn. For example, a person buying a personal computer may not know what attribute to look for. Many of the product features like 16K memory disc storage, screen resolution carry no meaning to him or her. This buyer will pass through a learning process characterized by first developing beliefs about the product, then attitudes, and then making a thoughtful purchase choice. The marketer of a high-involvement product must understand the information-gathering and evaluation behaviour of high-involvement consumers. The marketer needs to develop strategies that assist the buyer in learning about the attributes of the product class, their relative importance, and the high standing of the companys brand on the more important attributes. The marketer needs to differentiate the brands features, use mainly print media and long copy to describe the brands benefits, and motivate store sales personnel and the buyers acquaintances to influence the final brand choice. 2. Dissonance-Reducing Buying Behaviour: Sometimes the consumer is highly, involved in a purchase but sees little difference in the brands. The high involvement is again based on the fact that the purchase is expensive, infrequent, and risky. In this case, the buyer will shop around to learn what is, available but will buy fairly quickly because brand differences are not pronounced. The buyer may respond primarily to a good price or to purchase convenience. After the purchase, the consumer might experience dissonance that stems from noticing certain disquieting features of the product or hearing favourable things about other brands. The consumer will be alert to information that might justify his or her decision. The consumer will first act, then acquire new beliefs and end up with a set of attitudes. Here marketing communications should aim to supply beliefs and evaluations that help the consumer feel good about his or her brand choice. 3. Habitual Buying Behaviour: Many products are bought under conditions of low consumer involvement and the absence of significant brand differences. Consider the purchase of salt. Consumers have little involvement in this product category. They go to the store and reach for the brand. If they keep reaching for the same brand, it is out of habit, not strong brand loyalty. There is good evidence that consumers have low involvement with most low-cost, frequently purchased products. Consumer behaviour in these cases does not pass through the normal belief/attitude/behaviour sequence. Consumers do not search extensively for information about the brands, evaluate their characteristics, and make a weighty decision on which brand to buy. Instead, they are passive recipients of information as they watch television or see print ads. Ad repetition creates brand familiarity rather than brand conviction. Consumers do not form a strong attitude towards a brand but select it because it is familiar. After purchase, they may not even evaluate the choice because they are not highly involved with the product. So the buying process is brand beliefs formed by passive learning, followed by purchase behaviour, which may be followed by evaluation. Marketers of low-involvement products with few brand differences find it effective to use price and sales promotions to stimulate product trial, since buyers are not highly committed to any brand. In advertising a low-involvement product, a number of things should be observed. The ad copy should stress only a few key points Visual symbols and Imagery are important because they can easily be remembered and associated with the brand. The ad campaigns should go for high repetition with short-duration messages. Television is more effective than print media because it is a low-involvement medium that is suitable for passive learning. Advertising planning should be based on classical conditioning theory where the buyer learns to identify a certain product by a symbol that is repeatedly attached to it. Marketers can try to convert the low-involvement product into one of higher involvement. The ways are: ? This can be accomplished by linking the product to some involving issue, as when Crest toothpaste is linked to avoiding cavities. The product can be linked to some involving personal situation, for instance, by advertising a coffee brand early in the morning when the consumer wants to shake oft sleepiness. ? The advertising might seek to trigger strong emotions related to personal values or ego defense. ? An important product feature might be added to a low-involvement product, such as by fortifying a plain drink wit h vitamins, These strategies at best raise consumer involvement from a low to a moderate level; they do not propel the consumer into highly involved buying behaviour. . Variety-Seeking Buying Behaviour: Some buying situations are characterised by low consumer involvement but significant brand differences. Here consumers are often observed to do a lot of brand switching. An example occurs in purchasing cookies. The consumer has some beliefs, chooses a brand of cookies without much evaluation, and evaluates it during consumption. But next time, the consumer may reach for another brand out of boredom or a wish for a different taste. Brand switching occurs for the sake of variety rather than dissatisfaction. The marketing strategy is different for the market leader and the minor brands in this product category. The market leader will try to encourage habitual buying behavior by dominating the shelf space, avoiding out-of-stock conditions, and sponsoring frequent reminder advertising. Challenger firms will encourage variety seeking by offering lower prices, deals, coupons, free samples and advertising that presents reasons for trying something new.

Joblessness Essay Example | Topics and Well Written Essays - 2000 words

Joblessness - Essay Example Apart form the recession, dynamic changes like globalization and free trade has had a negative impact on the employment situation in the United States. Jobs have been outsourced at the cost of employment back home, leaving many people in a state of joblessness. This paper studies the impact of joblessness among the middle and upper aged population in the United States with reference to sociological perspectives. Middle aged joblessness results in financial and psychological stress, but has one advantage in the sense that such persons are better equipped to teach their children how to cope in the ‘new risk economy’. During the course of this research, four arguments will be discussed. The first one is that, the new risk economy is harsher on middle aged and older employees with regard to being jobless. The second is that, in times of recession in the economy, qualification, experience and age is given preference over youth and lack of experience. The third argument is that joblessness will lead to lower levels of commitment and will result in unemployed middle aged and older workers to become free agents. The fourth is that the life course of the jobless has changed drastically when shifting from the Fordist era to the new risk economy era. According to Goldsmith et al, unemployment has two adverse effects on the society, the economy, and the individual and their families. For them, â€Å"one is the output foregone that could have been produced if unemployed workers had been productively employed. The second is the psychological damage suffered by unemployed workers and their families† ( Goldsmith, Veum & Darity, 1996). Companies are now looking at minimizing costs in order to remain competitive, and one of the ways in which this is accomplished is through reduction in the number of employees. Increasing globalization coupled with

Monkey in the Mirror Essays Essay Example | Topics and Well Written Essays - 500 words

Monkey in the Mirror Essays - Essay Example But there are several things that mark us as being different from many of these other animals. Some of them are purely physical – for instance we have bipedal motion that is absent in the rest of apes (Tattersall, 2002 p. 89). But we also have many metaphysical qualities that mark us as different from our ancestors, such as the creation of music, art and culture. There is no one single thing that can truly account for all the ways in which we are different, but there are a few pieces that had to come together. One of which is our brain, which is by far the largest brain compared to body mass of any animal in the history of the world (Tattersall, 2002, p. 151). This probably had to develop in conjunction with a lot of other developments to be useful – for instance, larger brains would not have been useful if we were not already prehensile apes who were adapted to living in trees, and could thus use our prehensile hands to create and use tools (Tattersall, 2002 p. 69). Bu t probably one of the single things that sets humans apart from other animals the most is the development of speech. A change in our voice box and brain simultaneously occurred at some point in the evolution of homo sapiens, which allowed humans to differentiate themselves from previous iterations of humanity (or pre-humanity), and begin to do things that are truly novel in the animal kingdom Tattersall, 2002). One of the things that makes language so important is that it augments our innate intelligence, so that instead of things that become created instantly dying out when the person who created them dies, they can pass on the teaching to succeeding generations. This creates culture, which is probably the one biggest things that separates humans from other primates and other animals. If Gould and Tattersall were to have a conversation with each other, they would probably come to cross roads. Gould tended to entirely

Understanding The Terms Of Semiconductor Devices Information Technology Essay

Understanding The Terms Of Semiconductor Devices Information Technology Essay Semiconductors are materials which have a conductivity between conductors generally metals and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide. In a process called doping, small amounts of impurities are added to pure semiconductors causing large changes in the conductivity of the material. Semiconductor devices now influence our lives on a daily basis. Although insulators and conductors are useful in their own right, semiconductors such as silicon and gallium arsenide have dramatically changed the way in which billions of people live. Their intermediate ability to conduct electricity at room temperature makes them very useful for electronic applications. For example, the modern computing industry was made possible by the ability of silicon transistors to act as fast on/off switches. 1.2 History: Fig 1: History of Semiconductor Part 2: Project Overview 2.1 Types of Semiconductors 2.1.1 Intrinsic Semiconductors An intrinsic semiconductor is one which is made up of a very pure semiconductor material. In more technical terminology it can stated that an intrinsic semiconductor is one where the number of holes is equal to the number of electrons in the conduction band. The forbidden energy gap in case of such semiconductors is very minute and even the energy available at room temperature is sufficient for the valence electrons to jump across to the conduction band. Another characteristic feature of an intrinsic semiconductor is that the Fermi level of such materials lies somewhere in between the valence band and the conduction band. This can be proved mathematically which is beyond the scope of discussion in this article. In case you are not familiar with the term Fermi level, it refers to that level of energy where the probability of finding an electron is 0.5 or half (remember probability is measured on a scale of 0 to 1). 2.1.2 Extrinsic Semiconductors These are semiconductors in which the pure state of the semiconductor material is deliberately diluted by adding very minute quantities of impurities. To be more specific, the impurities are known as dopants or doping agents. It must be kept in mind that the addition of such impurities is really very miniscule and a typical dopant could have a concentration of the order of 1 part in a hundred million parts or it is equivalent to 0.01 ppm. The materials chosen for doping are deliberately chosen in such a manner that either they have 5 electrons in their valence band, or they have just 3 electrons in their valence band. Accordingly such dopants are known as pentavalent or trivalent dopants respectively. The type of dopant also gives rise to two types of extrinsic semiconductors namely P-type and N-type semiconductors. A pentavalent dopant such as Antimony are known as donor impurities since they donate an extra electron in the crystal structure which is not required for covalent bonding purposes and is readily available to be shifted to the conduction band. This electron does not give rise to a corresponding hole in the valence band because it is already excess, therefore upon doping with such a material, the base material such as Germanium contains more electrons than holes, hence the nomenclature N-type intrinsic semiconductors. On the other hand when a trivalent dopant such as Boron is added to Germanium additional or extra holes get formed due to the exactly reverse process of what was described in the upper section. Hence this dopant which is also known as acceptor creates a P-type semiconductor. Hence electrons are the majority carriers (of current) in N-type while holes are minority carriers. The reverse is true of P-type semiconductors. Another difference is that whereas the Fermi level of intrinsic semiconductors is somewhere midway between the valence band and the conduction band, it shifts upwards in case of N-type while it drifts downward in case of P-type due to obvious reasons. 2.2 Semiconductor Device (Diode): A diode is the simplest possible semiconductor device, and is therefore an excellent beginning point if you want to understand how semiconductors work. In this article, youll learn what a semiconductor is, how doping works and how a diode can be created using semiconductors. But first, lets take a close look at silicon. Silicon is a very common element for example, it is the main element in sand and quartz. If you look silicon up in the periodic table, you will find that it sits next to aluminum, below carbon and above germanium. A diode is the simplest possible semiconductor device. A diode allows current to flow in one direction but not the other. You may have seen turnstiles at a stadium or a subway station that let people go through in only one direction. A diode is a one-way turnstile for electrons. When you put N-type and P-type silicon together as shown in this diagram, you get a very interesting phenomenon that gives a diode its unique properties. Fig 2: Diode Even though N-type silicon by itself is a conductor, and P-type silicon by itself is also a conductor, the combination shown in the diagram does not conduct any electricity. The negative electrons in the N-type silicon get attracted to the positive terminal of the battery. The positive holes in the P-type silicon get attracted to the negative terminal of the battery. No current flows across the junction because the holes and the electrons are each moving in the wrong direction. If you flip the battery around, the diode conducts electricity just fine. The free electrons in the N-type silicon are repelled by the negative terminal of the battery. The holes in the P-type silicon are repelled by the positive terminal. At the junction between the N-type and P-type silicon, holes and free electrons meet. The electrons fill the holes. Those holes and free electrons cease to exist, and new holes and electrons spring up to take their place. The effect is that current flows through the junction. Part 3: Analysis 3.1 Application and Research The building block of most semiconductor devices involves combining p-type and n-type regions into p-n junctions. Imagine bringing together two crystals where one is n-type and the other is p-type. A few of the electrons from the n-type flow toward the p-type material. At the point where the p-type and n-type meet (the interface) electrons from the n-side fill the holes on the p-side and a build-up of oppositely charged ions is generated, and thus a potential across the barrier forms. This build-up of charge is called the junction potential. The barrier prevents further migration of electrons and the net current is zero. If a voltage is applied to the p-n junction with the negative terminal connected to the n-region and the p-region is connected to the positive terminal, the electrons will flow toward the positive terminal, while the holes will flow toward the negative terminal. This is called forward bias and current flows. However, if the positive terminal is connected to the n-type and the negative connected to the p-type, a reverse bias forms and no current flows due to the build up of the potential barrier. In other words, these devices must be placed in an electrical circuit with the correct polarity, or they will not function. This application of the p-n junction is used in many electronic devices. Figure 6 shows the formation of a potential at a p-n junction. Figure 7 shows the effect of forward and negative bias on the p-n junction. Figure 3: A p-n junction before and after the two materials are brought in contact. When the two materials are placed together, electrons from the n-side combine with the holes on the p-side. This results in a positive charge on the n-side of the junction and a negative charge accumulation on the p-side. This separation of charge creates a junction potential. Note: There are no electrons or holes at the junction, they have combined with each other. Figure 4: A p-n junction under forward and reverse bias. Notice that in forward bias, the barrier is lowered, while in reverse bias, the barrier is raised. Thought question: In each case in Figure 4, which side is connected to the positive terminal of the outside voltage source? Will electrons or holes carry current when the junction has this arrangement ? 3.1.1 Electronic Devices: There are many electronic devices that function using combinations of p-n junctions such as diodes, solar cells and transistors. In this section a brief explanation of each of these basic devices will be given. The diode is a p-n junction application that acts as a rectifier for converting alternating current to direct current. This is due to the ability of a diode to allow current flow in one direction but not in the other. Solar cells are p-n junction devices which use sunlight to create electrical energy. It is the energy of the sun`s photons that causes the electrons to be promoted into the conduction bands and carry the current. However, the current derived from the solar cell is small. It takes many solar cells to produce enough current to do a large scale job. If the energy output from solar cells could be increased, solar energy could be used for more than individual, isolated applications. Transistors are another application of the p-n junction. Transistors, unlike diodes, contain more than one p-n junction. Because of this, a transistor can be used in a circuit to amplify a small voltage or current into a larger one or function as an on-off switch. Transistors are of two main types: bipolar junction transistors (BJTs) and field effect transistors (FETs). Roughly 95% of all electronic systems utilize one or both of these types of devices. BJTs are composed of three layers of doped materials, either n-p-n or p-n-p in configuration. The BJT acts like a bump or dam in an open stream to control the amount of current let by; thus as the bump is lowered, more current can flow. In the BJT, the height of the bump is controlled by the base current in the semiconductor. The BJT was invented in 1948 by John Bardeen, Walter Brittain and William Shockley using germanium. BJTs remained the only important three terminal semiconductor devices for about a dozen years after their invention, and helped to launch the modern electronics era. Since the early 1960s the FET has been considered one of the most important devices in solid state technology. At present, many of the applications of BJTs have been taken over by metal-oxide semiconductor FETs (MOSFETs). MOSFETs were theorized for many years before they were able to be manufactured. The reason MOSFETs could not be made was that scientists had not yet developed techniques for growing high quality silicon dioxide (SiO2) on silicon. The FET functions more as a gate for controlling the flow of current (like a valve on a faucet). FETs are relatively simple to fabricate compared to BJTs, and they have proven to be extremely fast, reliable switches in miniaturized circuit components with much less power usage than BJTs. Most modern microprocessors are based on FET devicesfrom pentium chips in PCs to the CPUs of super computers. Transistors, diodes, and other electronic devices are combined in many different patterns to form todays integrated circuits. The integrated circuit (IC) has been the workhorse of the microelectronics era which began in the late 1950s. These chips, usually made of silicon, consist of combinations of four fundamental electrical regions. These regions contain resistors, capacitors, diodes and transistors. Since 1971, Very Large Scale Integration (VLSI) has allowed millions of such regions to be fabricated on a chip that is only one square centimeter. Not only are these circuit elements getting smaller, they are getting faster as well. For example todays typical desktop pentium-based computer can perform tens of millions of operations per second, whereas contemporary super computers are rated in gigaflops (billions of operations per second). Teraflop (trillions of operations per second) machines will be ready for production by the year 2000. 3.2 Semiconductors Applications Worldwide We mentioned just a few of the many different applications of semiconductor devices. The use of these devices has become so widespread that it would be impossible to list all their different applications. Instead, a broad coverage of their specific application is presented. Semiconductor devices are all around us. They can be found in just about every commercial product we touch, from the family car to the pocket calculator. Semiconductor devices are contained in television sets, portable radios, stereo equipment, and much more. Science and industry also rely heavily on semiconductor devices. Research laboratories use these devices in all sorts of electronic instruments to perform tests, measurements, and numerous other experimental tasks. Industrial control systems (such as those used to manufacture automobiles) and automatic telephone exchanges also use semiconductors. Even today heavy-duty versions of the solid-state rectifier diode are being use to convert large amounts of power for electric railroads. Of the many different applications for solid-state devices, space systems, computers, and data processing equipment are some of the largest consumers. The various types of modem military equipment are literally loaded with semiconductor devices. Many radars, communication, and airborne equipment are transistorized. Data display systems, data processing units, computers, and aircraft guidance-control assemblies are also good examples of electronic equipments that use semiconductor devices. All of the specific applications of semiconductor devices would make a long impressive list. The fact is, semiconductors are being used extensively in commercial products, industry, and the military. 3.3 Power semiconductor devices for DC/DC converters As the performance of servers, notebook PCs and graphics cards increases, their power consumption grows as well. At the same time, the trend toward lower operating voltages for components such as CPUs, graphics processing units (GPUs), memory devices and ASICs results in increased current flow. This creates a need for DC/DC converters capable of handling low voltages and large currents. Renesas 12th-generation power MOSFETs, the RJK0210DPA, RJK0211DPA and RJK0212DPA are now available for service in DC/DC converters, which operate by having two power MOSFETs, one for control and the other for synchronous rectification, switching on and off alternately to convert the voltage.   For example the new RJK0210DPA MOSFET is used for control and the Renesas Electronics 11th generation RJK0208DPA device can be used for synchronous rectification. Refinements to the manufacturing process allow the new Renesas MOSFETs to achieve approximately 40 percent improvement in FOM (figure of merit; on-state resistance times gate charge) compared to the companys existing products, which contributes to reduction of the power loss during voltage conversion and thereby enables highly efficient DC/DC converter performance. Using the Renesas Virtual Power Lab MOSFET Design Tool lets you check out these and other MOSFETs without the hassle of waiting for device samples, then having to solder the parts down on test boards.   This tool lets engineers evaluate various solutions in a virtual real-time environment to facilitate the selection of optimum MOSFET combinations for synchronous buck-converter applications. Among its benefits: helping you find the right MOSFETs and interactively get help designing your sync buck converter application; analyzing performance, switching behavior and efficiency of your new buck converter design; evaluating MOSFET behavior under a variety of operating conditions using an interactive datasheet and downloading SPICE models. 3.4 Importance Of Semiconductor in Technologies: Due to their role in the fabrication of electronic devices, semiconductors are an important part of our lives. Imagine life without electronic devices. There would be no radios, no TVs, no computers, no video games, and poor medical diagnostic equipment. Although many electronic devices could be made using vacuum tube technology, the developments in semiconductor technology during the past 50 years have made electronic devices smaller, faster, and more reliable. If we think for a minute of all the encounters we have with electronic devices. How many of the following have we seen or used in the last twenty-four hours? Each has important components that have been manufactured with electronic materials. microwave oven, electronic balance, video games, radio, television, VCR, watch, CD player, stereo, computer, lights, air conditioner, calculator, telephone, musical greeting cards, diagnostic equipment, clock, refrigerator, car, security devices , stove Fig 5: Clockwise from top: A chip, an LED and a transistor are all made from semiconductor material   Source: http://static.howstuffworks.com/gif/solid-state1.jpg Semiconductors have had a monumental impact on our society. We find semiconductors at the heart of microprocessor chips as well as transistors. Anything thats computerized or uses radio waves depends on semiconductors. Today, most semiconductor chips and transistors are created with silicon. You may have heard expressions like Silicon Valley and the silicon economy, and thats why silicon is the heart of any electronic device. 3.5 Future Trends Since the late 1950s, the discovery and invention of new electronic semiconductor materials and the drastic reduction in the size of electronic devices has moved at a rapid pace. As a result, the speed of electronic devices (particularly integrated circuits) has grown exponentially over the same time period. Great strides have been made by companies such as Bell Laboratories, Intel, Western Electric, American Telephone and Telegraph, Motorola, Rockwell, and IBM. In 1975, Gordon Moore gave a famous talk at the International Electronic Devices Meeting (IEDM) in which he predicted a growth in microchip complexity of roughly a factor of two every year. In most areas of electron device production, his predictions have been met or exceeded. The push for smaller dimensions, which allow for increased functionality and faster devices, also creates problems of long term reliability and heat dissipation. New device designs, new materials, and lower voltages are being employed to make the next generation of devices. One extremely important area of semiconductor technology is the field of telecommunications. The new Information Super Highway requires technology which can transmit and receive information at high rates. One approach which is already being applied to this area is optoelectronics or the use of light to transmit information. Electrons are used to transfer information within computers, but most information sent over long distances uses light pulses traveling through fiber optic cables. The laser diodes which create these pulses and semiconductor receivers that detect the pulses are areas of intensive research. It is clear that semiconductor technology has and will continue to play a major role in the development of the information age. Part 4: Conclusion After the completion of the term paper on Importance Of Semiconductor discovery on Technology I got many new things to learn about. The term paper includes brief description on semiconductors, it also contains the types of Semiconductors and brief description of it. The term paper also gives the importance of Semiconductor in our day today life. It also explains the applications of semiconductor and its uses in some of the technologies. The term paper also gives future trends and research of semiconductor. Through this term paper I wanted to give the reader few ideas about what are semiconductors and about its importance. I have worked very hard on this project and wanted to build it in a very simple and lucid manner so that it could be easy for the reader to go through and understand the term paper. Hopefully, I think that you would have gained some knowledge on semiconductors and could have well understood it. I grant a sincere apologize if any mistake would have crept in my work.

Small Gods :: essays research papers fc

â€Å"Small Gods† The World rides through space on the back of a turtle. This is one of the great ancient world myths, found wherever men and turtles were gathered together; the four elephants were an Indo–European sophistication. The idea has been lying in the lumber rooms of legend for centuries. All I had to do was grab it and run away before the alarms went off. Discworld is based on a slew of old myths, which reach their most 'refined' form in Hindu mythology, which in turn of course derived from the original Star Trek episode 'Planet of Wobbly Rocks where the Security Guard Got Shot' (Pratchett, Terry. Equal p 216). Terry Pratchett is the author of a popular fantasy series that is set in Discworld, a planet that is as flat as a pancake. It sails on forever, a flat, circular world carried on the backs of four elephants supported on the back of A’tuin, the giant space turtle. The turtle doesn’t stand on anything, so don’t ask. It swims on through the infinite universe (Huckaby n.pag.). In his book Small Gods, Terry Pratchett succeeds in satirizing most of the world’s major religions and a few ancient political policies by expressing his thoughts and feelings through his own brand of humor and witticism. In the Discworld, there are a numerous amount of gods, powerful and weak. Small Gods takes a look into the realm of Ominia, a vast empire devoted to the Greater Glory of their god Om. The Gods of Discworld have a very unique power source. Their power depends upon having believers; a god with no believers fades into a powerless, wandering spirit or dies. The Great God Om has a powerful church, yet has only one real believer, a novice monk named Brutha. Drained of supportive power, he finds himself trapped in the body of an ordinary tortoise. Imagine the discomfiture a god might experience if confronted with some of the beliefs taught in his name -- and some of the "divinely inspired" actions taken by his followers as a result. Om, in his little tortoise shell, also comes to the disconcerting realization that, while his religion is vast and has many zealous worshippers, he has very few actual honest-to-Om believers. One, actually (Knapp n.pag.). Pratchett shows a struggle between a god and his religion, which no has no room for him. He shows a cynical side like most British humorists in that there may be religions existing whose god died out long ago from lack of belief.

Homework 6

According to the dependency theory, the high-income, more-developed nations can improve their standard of living only with a period of intensive economic growth and accompanying changes in people’s beliefs, values, and attitudes toward work. False According to social scientists, absolute poverty exists when people may be able to afford basic necessities but are still unable to maintain an average standard of living; it is measured by comparing the actual income against the income earner’s expectations and perceptions. FalseAnalysts using a development framework typically view industrialization and economic development as essential steps that nations must go through in order to reduce poverty and increase life chances for their citizens. True * Of all age groups, persons aged 65 and over are the most likely to be uninsured in the United States. False * * Global stratification refers to the unequal distribution of wealth, power, and prestige on a global basis, resulting i n people having vastly different lifestyles and life chances both within and among the nations of the world.True * * Intragenerational mobility is the social movement experienced by family members from one generation to the next.
