Catcher In The Rye-Does Voice Matter Essays - Literary Realism

Catcher In The Rye-Does Voice Matter Does the Voice Matter? How important is the voice that tells a story? It seems almost trivial to claim that the same story can change because of the voice telling it to you. Does the voice and point of view of the narrator play a large enough role in a novel to change the attitude of the reader about the novel? J.D.. Salinger uses the dominant character of Holden Caulfield to be the first person narrator of his novel The Catcher in the Rye. The key to Holden's narrative voice is the fact that it added life and a connection to the character. This voice transforms an otherwise lifeless story to a jump start and electric novel. In order to find out how important this narrator was to the story we will compare the novel The Catcher in the Rye to the piece ?A Slight Rebellion of Madison?(the summary of the very same novel as told in third person omniscient). In looking at the importance of Holden's role we will first look at the summary of the novel. In ?Slight Rebellion off Madison? the character of Holden Caulfield has been eliminated and an outside third person narrator replaces him. This version goes through the story explaining the basic outlining of The Catcher in the Rye. The outline is what the summary gives to the reader and that's all it gives. The basic plot is average, but with out the connection to the reader it keeps the reader on the outside through the whole thing. The plot tells the happenings of a young man named Holden Caulfield, but without really knowing to much about the character of Holden the plot line is lifeless and boring for the reader. We see the experiences that Holden goes through, but the reader doesn't get involved. It is hard for most readers to sympathize with Holden therefore Salinger relies on the connection Holden makes with the reader to get the reader involved in the life of Holden. What about Holden's narrative voice causes such a giant impact on the novel? I s it his loud personality or just that the reader is allowed to but put in the position as his best friend. Salinger starts the novel right away with Holden trying to relate to the reader. ?If you really want to hear about it, the first thing you'll probably want to know is where I was born, and what my lousy childhood was like, and how my parents were occupied all before they had me, and all that David Copperfield kind of crap, but I don't feel like going into it, if you want to know the truth.? Throughout the entire novel Holden uses slang and swear words to give the reader a more familiar feeling to him. Salinger makes it seem as though Holden is confiding everything to the reader. this is the key to the novel and why it is more than a simple story line. Book Reports

Some countries consider tourism as a source of income and government revenues in addition to agriculture and industry or even oil and gas products. This report describes the important and major role tourism plays in the macroeconomic and microeconomic of some countries. This report also gives a brief account about tourism and microeconomics in the UAE, and the plans which include strategic objectives to closely connect tourism with micro businesses, demand, supply and local services as well as recreational facilities. Many countries, especially some developing countries like Caribbean countries, Kenya, Tunisia, Indonesia, Thailand and Egypt have tourism as the main income for local development, foreign currency, and poverty reduction and for economic growth. They invest on tourism considering it as their major industry. They ave it as a remedy for local economic development and to solve problems like unemployment. In this way they generate higher income for the local economic circuit, for individuals like taxi drivers, storeowners etc. , and for hotels, restaurants and local firms To attract tourists such countries build the required infrastructure like hotels, resorts, communication, roads, parks and other recreational facilities, which in turn aff ects demand and supply of many commodities. Moreover, â€Å"Community support is important for tourism, as it is an activity that affects the entire community. Tourism businesses depend extensively on each other as well as on other businesses, government and residents of the local community. Economic benefits and costs of tourism reach everyone in the region in one way or another. † In countries that depend on tourism as number one industry, tourism economy affects their, policy, strategic decisions and planning as it may reflect on the whole of its community and microeconomic. In addition to the plans for building the suitable infrastructure, they have to conduct economic impact studies, analysis and assessment to support decisions related to tourism. They have to know the contribution of tourism to the economy of the country, the government income from taxes and fees and whether the revenues of tourism will cover the cost of services in addition to making sufficient profits. They also have to conduct environmental impact assessment in order to know the effects on social, cultural, microeconomic, biological, physical, and ecological systems. Tourism microeconomic impact studies are vital for countries which depend on tourism industry as the main income. The studies and analysis will answer many questions that affect policies, planning and strategic decision making as well as actions to encourage tourism activity. The results of the studies include the amounts of money tourists spend, the portion of sales by local businesses, the income tourism generates for households and micro businesses, the jobs tourism support and taxes that are generated by tourism. It is worth mentioning that not only poor countries pay attention to the importance of tourism. There are some rich countries that care about tourism. United Arab Emirates is a good example. Although they have sufficient revenues from oil and gas exports but at the same time they have long term plans to promote tourism. They â€Å"made significant investments to diversify beyond oil production and enhance the quality of its business environment. † There are â€Å"numerous world-class development projects throughout the UAE especially in Abu Dhabi and Dubai – from new luxury hotels, resorts, leisure attractions and shopping malls, to low, mid and high-income residential communities – that dramatically attracts visitors. For example in Abu Dhabi â€Å"Saadiyat Island is undergoing remarkable transformation that will become a world-class leisure, residential, business and cultural hub. Saadiyat Island’s Cultural District will house the world’s largest single concentration of premier cultural assets, including the Lord Norman Foster-designed Zayed National Museum, the Louvre Abu Dhabi and Frank Gehr y-conceived Guggenheim Abu Dhabi. A performing arts centre and a maritime museum will add to the portfolio of leading cultural institutions. There will be also Manarat Al Saadiyat, Monte Carlo Beach Club, Mesopotamia exhibition, Beach Golf Club, Zayed National Museum. Another interesting and entertaining place is Yas Island which includes Marina Circuit, Yacht Club, Abu Dhabi Grand Prix, Ferrari World Abu Dhabi and many more interesting places. Such projects enhance the microeconomic in UAE. Moreover, in Dubai there are many projects that attract visitors which in turn encourage tourism and increase expenditure. The following figures and facts show the microeconomic competitiveness of the UAE and Dubai logistic and tourism cluster maps. Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Clusters in the UAE Remarks: Cluster developments include all emirates while the efforts that are made by each Emirate are not the same. The main efforts are made by Abu Dhabi and Dubai. The present UAE’s clusters support the infrastructure investments, and the attraction of outside companies and foreign manpower. In spite of the remarkable efforts made by the experts and the departments of UAE overnment, the success in making clusters is still not comprehensive, but The UAE is still better in cluster-based economic variations than some other oil-dependent economies. The building of better, more developed and sustainable clusters is still important for UAE government. Competitiveness in the Regions Economic performance of each country is deferent. Local policies and investments may help all countries i n the region make much more efforts in competitiveness. To improve competitiveness there should be more coordination and cooperation among the individual Emirates and other GCC countries. â€Å"Different emirates have developed their own economic strategies, e. g. , Abu Dhabi Economic Vision 2030 and Dubai Strategic Plan 2015† Figure 6 Dubai Tourism Cluster Map Finally, it is true that tourism has some disadvantages with regards to demand and supply, prices, environmental pollution, cultural and traditional lifestyle degradation, but in our opinion tourism is and will remain a source of profit and has many more advantages especially to microeconomic growth and in creating different levels of employment for people as well as a source of profit to individual and firms business.

Deadlock Characteristics and Solutions Research Paper

Deadlock Characteristics and Solutions - Research Paper Example When a process cannot change its situation indefinitely due to another waiting process using the same resource, then this leads to a system being in deadlock (Kaveh and Wolfgang). Under normal circumstances, resource allocations in a system undertake the following steps. A process requests a resource and the process is suspended until the resource is available. The process then uses the resource once it has been allocated. Finally, the process releases the resource. A system might have two processes running process-A and process-B namely. The situation above illustrates that Process-A and Process-B are in a deadlock state. Deadlocks have the following assumptions. The process cannot be allocated a resource before it requests for it. Therefore, the order it follows is request then use it and release the resource. A process can also only request more resources than the number of resources available for use by the system. Multiprogramming systems have a resource table than manages resources by showing free and occupied resources being used by processes. It also keeps queues of the processes that are waiting for certain resources. The queues will indicate the time a resource will be released by a process thus making it available for use by other resources. Mutual exclusion occurs when one or at least one of the resource is not sharable. It means that only a few numbers of processes can use the resource at a time. A requesting process has to wait for a resource to be released if it requests the process when it is being used by another process. To illustrate mutual exclusion, Process-A can have an exclusive control of a resource that Process-B needs and vice versa. Process-A and Process-B will block indefinitely while waiting for one process or other processes to free the resource. Mutual exclusion is not restricted to objects in the computer

Starbucks ethics negative side Assignment Example | Topics and Well Written Essays - 500 words

Starbucks ethics negative side - Assignment Example Interest of the enterprises to follow and adopt business ethics as part of their functioning has fallen down during the recession period, with unethical practices indirectly leading to recession. (Purlys 711). Starbucks is under this ethical scanner for a long time, and now the global changes on how companies should function ethically, make it imperative on the part of Starbucks to be more ethically sound, but that is not the case, with Starbucks facing problems in organizing in the changing global environment. Although, Starbucks wants to establish itself as the most recognized and respected brand in the world, it is facing some ethical issues and it is negatively affecting its organizing efforts in the changing environment. Starbucks is facing criticism for unethical as well as controversial activities like not compulsorily providing Fair Trade Coffee in all its stores and because of the use of Bovine Growth Hormone milk in its coffees and ice-creams. Fair Trade Coffee is the term given to the coffee beans, which are purchased by Starbucks or other coffee makers through ethical means like providing fair and industry standard prices to the coffee growers in the Home country as well as in the Third World countries. Also, Fair Trade activities including Fair Trade Coffee support and intersect with other community development efforts, grounding and enhancing the resulting benefits (Raynolds, Murray and Taylor 1116). However, Starbucks is accused of not selling these Fair Trade coffees in all its stores compulsorily, instead selling only to the clients, who ask for it or demand it. This way, they still selling non-Fair Trade coffees and because of this unethical practice, they are giving very low prices to the farmers, forcing them into a cycle of poverty and debt, and also not doing enough community services for them. Although, Starbucks’ chairman, Howard Schultz mandated that coffee farmers from its major sources in the African countries

Star Wars Essay Example | Topics and Well Written Essays - 2000 words

Star Wars - Essay Example While it is no doubt Star Wars deals with advanced technology many of which have not yet been established, Star Wars also talk about the existence of Force which is actually a mystical energy field that provides magical energy to Jedi. Considering both scientific elements and mystical power shown in Star Wars, can the films be seen in the genre of both sci-fi and fantasy. Today, science fiction has become a kind of reflection of â€Å"mythology of our times† (Sutton & Sutton, 1969, p.230). Myth has been described by Fontenelle as science that has been conceived in the primitive era by observing the causes of events. In the 19th century, Andrew Lang has explained that myth is human being’s effort of understanding the mysteries of the world through the lens of science. It is now no longer possible to assume myth as prescience. According to Levi-Strauss theory, myth and science are two parallel modes of explaining the universe. They are mutually exclusive and two different ways of explaining the same thing. In earlier days, myth was used by man to understand his own origins while science is used as a tool to study destiny (Sutton & Sutton, 1969, p.231). Today science fiction is accepted as mythical exploration of scientific technology, and therefore Levi-Strauss’s theory does not hold good regarding the two concepts as parallel auto nomy. There is now a clear intersection of the mythopoeic and scientific modes. According to Thoman C. Sutton and Marilyn Sutton (1969, p.231) â€Å"myth and science reflect man’s irrepressible curiosity about his origins and his destiny, they each can be seen as a particular human means of structuring the universe†. The authors consider science fiction as scientific myth more than religious myth in which man holds the major power. Star Wars is a classic story that talks about man turning evil and his son attempting to amend him. Basically it is a story about good and evil and set in another galaxy in another

Effects Of Classroom Lighting On Filipino College Students

Effects Of Classroom Lighting On Filipino College Students Several studies on the effects of lighting on students academic performance had been done abroad on different social classes and ages of the subjects. These all had the objective of improving the learning process of students during their formative years at school. According to Bukky Akinsanmi, theories on how learning takes place include behaviorism, cognitivism, and constructivism. The behaviorism theory, which was popularized by B.F. Skinner, supports the idea that humans come into this world like a blank slate tabular rasa. Humans learn based on reinforcements. Rewards are given to those whose action reaps positive results. Punishments are given otherwise. The effective transfer of knowledge is the teachers responsibility leaving the student a passive participant. It is teacher-focused, structured, lecture-based, and uses reward and punishment to promote learning. The classrooms provided little room for flexibility. Lapses on behaviorism theory include the eventual possibility of extinction of positive results when rewards are removed and the attitude of just doing things for the sake of rewards. Since the behaviorism theory does not account for all learning, the cognitivism theory came into existence. It says that the mind is a black box that must be opened and understood. It focuses on the study of mental processes. Schools were built in single or two-story buildings connected by walkways housing students according to their grades. Meanwhile, Constructivism theory states that knowledge is constructed and not acquired. The learning process is now the responsibility of the student and not the teacher. It says that humans are like blank slates making meanings from experiences. Unlike the behaviorism design of school environment, this theory supports student-centered, collaborative, cooperative, and experiential learning facilities with teachers serving as facilitators (Akinsanmi, 2008) To enhance students academic performance, the effective coordination of school environment must be studied. The physical characteristics of a school environment directly influences both the teachers way of imparting knowledge on students and a students performance at school. Such characteristics include sounds, temperature levels, and classroom lighting (Tope, 2013). Poor school facilities like inoperative heating system, inadequate ventilation, and poor lighting affect health, learning, and morale of students and staffs. Good overall building condition; including features such as large windows, natural lightings, and well-designed skylights on classroom settings; results to better students academic achievement (Vandiver, 2011). According to Robert Scott McGowen, the illumination of our surrounding environment impacts our reactions, motivations, moods, and sense of well-being. For centuries, this issue of illumination led to evident designs in architecture and natural lighting. Different degrees of illumination can be used to stimulate productive and creativity in offices and schools. Several studies had been done on providing windows or skylights in classrooms resulting to higher standardized tests. However, it does not clearly imply that the improvement in students performance was due to increased light, quality of light, or physiological effect of natural lighting. Windowless spaces contribute to negative attitudes of students as well as their teachers especially when coupled with monotonous tasks. It was shown that natural lighting can improve the quality and quantity of lighting in instructional areas effectively. Daylight has been and is still the standard by which artificial light is measured. Researc h reports indicate a positive correlation between day lighting and academic performance. Good quality of lighting increases comfort and increased comfort contributes to higher scores and academic performance of both teacher and students. The developmental stages of students are also considered when designing lighting systems. It is a physical support on students to help them concentrate on their academic endeavors. Recently, the focus on effective learning environments has shone on healthy physical surroundings (McGowen, 2007). Changing the facilities creates a different learning environment. Creating change has a major impact on students, faculty, and administrators. This change creates the type of learning environment, which is more conducive to learning and performance. (Vandiver, 2011) Two field studies and one experiment were done with Dutch elementary school children to examine the effects of dynamic lighting on concentration done by Sleegers, Moolenar, Galetzka, and Van Der Zanden. In the field studies, the pupils in the experimental conditions were subjected to different lighting settings and conditions during one day for a longer period of time (Study 1) or were constantly exposed to the focus setting for one month (Study 2), while the pupils in the controlled environment were subjected to the same lighting conditions during one morning (Study 3). They focused on pupils concentration performance and evaluated the impact of different lighting conditions and settings on pupils concentration. They also examined the differential effects of classroom lighting conditions on concentration for gender. They evaluated the effects of lighting, conducting analyses of variance, using three samples of data from 181 elementary school children. The results of their field stud ies offer support for the positive influence of classroom lighting conditions on concentration. Although all pupils performed better at the concentration test at the consecutive measurement points, it appeared that the performance of the pupils in the experimental groups improved more than the performance of their peers in the control groups. Furthermore, the findings of the first field study show differences between grades: they found effects of lighting on concentration for pupils from grade 4, but not for pupils from grade 6. These findings suggest that older pupils concentration might be less affected by the lighting conditions used than younger pupils. Hypothesis states that older pupils are more trained to concentrate while performing tests than younger pupils. On the other hand, the findings on the second field show that, on the average, older children perform better on concentration tests than their younger peers, no additional support was found for the role of age in the ef fect of lighting on concentration. Meanwhile, the results of the third study showed no statistically significant effect of lighting on concentration and so not substantiate the findings of the two field studies in a controlled environment. It might be because of the differences in the designs used. It suggests that the statistically significant differences found in the field of studies might be caused by uncontrolled extraneous influences that might limit or bias observation. It might also be that differences in the way children were exposed to the lighting conditions and settings in the different environments caused the differences between the findings. Although they did not evaluate the dynamic nature of the light system used, their findings seem to suggest that an environment in which different lighting settings and conditions are used to support specific activities and tasks at hand during a longer period of time may be more effective for pupils learning than an environment in w hich pupils are exposed to the same lighting condition for a relatively short period of time. The effect of lighting might be situation, task, and time dependent as previous studies also have indicated. The differences between the findings of the field studies and the third study for the relationship between lighting and concentration may also have to do with seasonal effects. Seasonal effects were also found in a more recent study into the effects of dynamic lighting on student alertness in a lecture room environment. The results of that study showed that in spring no change in alertness could be detected, while in the autumn study the decrease of alertness during lectures was significant. These findings shed light on the effects of exposure to lighting conditions during different seasons and the effect of the dynamic nature of light. As such, attention should be paid to the added value of artificial lighting in combination with exposure to daylight for the improvement of the perfo rmance of students in educational settings. Third, the results of their field studies showed no evidence of differential effects of gender in the relationship between lighting and concentration. Although earlier studies did find effects of lighting on performance and mood differ between men and women, their findings do not indicate gender related effects of lighting on pupils in elementary education. This may be related to the difference between children and adults in effects of lighting, for instance in regard to the development of psychological and affective preferences for the environment in general, and lighting specifically. (Sleegers et. al., 2012) According to Warren Hathaway, a search for ways to improve education is sustained by the general view that the learning environment is an important aspect in the educational process and the specific findings of research into the effects of types of lighting on people. Among the most surprising findings from the research in this field were that those elementary students who received trace amounts of ultraviolet light in their classrooms developed fewer dental carries and had better attendance than students in a comparison group. Sunlight is still the most important source of light and energy for living organisms and it may be experienced as direct light or as skylight. Most people do their works each day under the influence of sunlight. However, as society becomes more urbanized, people spend much less time under sunlight and much more time under artificial lamps. We are surrounded by walls, floors and ceilings covered with colors seldom repeated on the same scale in nature and these colors are usually perceived under lighting systems designed more for efficiency than for their possible physiological or psychological effects on people. Indeed, our artificial lighting systems can only simulate twilight levels of illumination-light levels of 200 to 1500 lux in comparison to light in the natural environment at twilight of 2,800 to 8,200 lux and at noon up to 100,000 lux. There is significance of wide differences in light levels between natural settings and built environments. Corth contended that the natural environment of our earliest ancestors was not the open plains but the forest floor. As a consequence, the habitat noon-time light levels would have been much lower than the 8,200 to 100,000 lux found in open areas. Moreover, he further contended that the spectral quality of the light at the forest floor was greenish-yellow and represented the combined result of the solar radiation spectrum and the filtering effect of the forest canopy. He also progressed the vi ew that our ancestors only later they occupied the forest floor near the equator did they move onto the open plains either north or south of the equator. Thus he concluded that heavy skin pigmentation was a matter of camouflage for survival more than it was a filter against UV light. As humans left the forest cover and moved into the more open country to the end of the equator and away from zones of intense UV light, the pigmentation was reduced as a response to the need for increased vitamin D which is formed by the action of ultraviolet light on the skin. Following Corths logic, one might expect two effects. First, in as much as the light spectrum of cool-white fluorescent lamps approximates that of the greenish-yellow light reaching the forest floor, people may find these lights to be very satisfactory. Second, if skin pigmentation decreases as a response to an increased need for ultraviolet light, highly pigmented people living in northern climates may have greater needs for ult raviolet stimulation than do lightly pigmented people. Sunlight contains all colors in relatively uniform amounts and all colors are equally visible when illuminated by sunlight. For this reason, natural light serves as the reference for comparing the color rendition characteristics of artificial lights, with natural light having the maximum or reference Color Rendition Index (CRI) of 100. The color rendition index is a measure of the way colors look under specific light sources. It is important to note that equivalent CRI indices mean the same thing only when the light sources to which they relate have equivalent color temperatures. As a consequence, colored objects may appear different when viewed under lights with different color temperatures but equivalent CRI indices. Not all artificial light sources accurately reproduce the full spectrum of sunlight. Incandescent lights are rich in red and yellow light, but radiate relatively little energy in the blue and green region of the s pectrum. Cool-white fluorescent lights emit most of their radiant energy in the green and yellow bands of the spectrum, the range to which eyes are most sensitive. Thorington asserted that it is at the 555 nm that the lumen or the standard unit of light is defined. Full spectrum lights emit a significant portion of their radiant energy in the blue area of the spectrum. A further small percentage of the radiant energy from fluorescent lamps may fall into the ultraviolet range. Rooms lit with full spectrum fluorescent lights may be seen as being somewhat dimly lit since the eye is less sensitive to blue light than to green and yellow light,. Full spectrum lights do, however, have a relatively high Color Rendition Index and this may be very important to vision processes. In this regard, Aston and Bellchainbers compared high efficiency with lamps that provided a spectrum more closely balanced to natural light. In their report they said, The results clearly show that the Kolorite lamps, lamps simulating natural light in spectral distribution, not only provide better color qualities but give a higher degree of visual clarity than do the high efficacy lamps at an equivalent illuminations. Ozaki and Wurmm drew attention to the fact that light from high pressure sodium vapor lamps produced anomalies in the growth and development of animals. They presented evidence to the effect that the exposure of developing rats to high pressure sodium vapor (HPSV) lights caused characteristic changes in growth and development. Downing concluded: There is no area of our mental and bodily functioning that the sun does not influence. Our bodies were designed to receive and use it in a wide range of ways. We were not designed to hide from it in houses, offices, factories and schools. Sunshine, reaching us through our eyes and our skin, exercises a subtle control over us from birth to death, from head to tail. Zamkova and Krivitskaya augmented regular fluorescent light with ultraviolet s untan lamps in a controlled experiment involving school children and they reported that when compared to the control group, students who received exposure to ultraviolet light showed increased levels of working ability and resistance to fatigue, improved academic performance, improved stability of clear vision, and increased weight and growth. Volkova studied the effects of ultraviolet supplements to general lighting in a factory and found that when compared to a control group, an experimental group of adults demonstrated decreased permeability of skin capillaries, increased white cell activity, and reduced catarrhal infections and colds. Richard Wurtman concluded that light has biological effects that are important to health and that some of these effects may be easily reproduced and measured in the experimental laboratory. These effects were of two kinds: those which modify the individuals endocrine, hormone and metabolic state by means of light reaching the retina and those which result from light on the skin. He also linked light entering the eye with responses of the pineal gland and secretion of the hormone melatonin. This hormone in turn influences the functions of other glands, possibly as a result of direct action on specific areas of the brain. Wurtman and Weisel studied the effects of light from cool white lamps and full-spectrum Vita-Lite lamps on a group of rats. Their findings support the argument that environmental lighting has an effect on at least some neuroendocrine functions. Himmelfarb, Scott, and Thayer reported that light from Vita-Lite (full-spectrum) lamps was significantly more effective in killing bacteria than light from standard cool-white lamps. Downing offered evidence that small amounts of ultraviolet radiation destroy bacteria and moulds. Relatively small amounts of ultraviolet light can stimulate calcium absorption among elderly men who have no exposure to sunlight and who eat a diet containing little vitamin D. Mass, Jayson, a nd Kleiber reported that students studying under full-spectrum lights had the smallest decrease over time in critical flicker fusion and an increase in visual acuity. Students studying under cool-white illumination demonstrated greater lethargy than those studying under full-spectrum lights (Hathaway, 1994). Sleegers suggested that future research should, therefore, focus on the interaction between light conditions and settings, specific activities and tasks and duration. This may increase our understanding of the variability of the effect of lighting among classroom environments, school activities, tasks and student performance and the potential effects of dynamic lighting in school settings. More research is needed to test the effects of different lighting conditions and settings on the school performance of different age groups. Future studies should use reliable and repeated measurements of concentration in order to reduce bias, increase the validity of the design used and evaluate the possible long term effects of lighting on school performance of young children in natural school environments. More systematic research is needed on the relation of daytime and artificial light, concentration, and seasonal effects, using objective measures to analyze performance in real life settings a nd with prolonged exposure. By doing this, the findings of these studies may help to increase our understanding of person/environment interaction and its impact on the performance and learning of elementary school children (Sleegers et al, 2012). At the same time, the literature on the non-visual effects of types of lighting on people is constantly expanding and from this there emerges a need to examine a variety of types of lighting for non-visual effects on people (Hathaway, 1994).

Gabriel Garcia Marquezs Love in the Time of Cholera :: Essays Papers

Gabriel Garcia Marquez's Love in the Time of Cholera Gabriel Garcia Marquez, author of Love in the Time of Cholera, depicts his characters by having them act in certain ways, in ways of love and care towards others. Each character acts certain ways to certain people, either to gain respect, love, friendship or hatred. Marquez’s character Florentino Ariza, is desperately in love with Fermina Daza, a beautiful young lady (early in the novel), who promises him her hand in marriage then breaks that promise by marrying Dr. Juvenal Urbino. Although heartbroken Ariza’s love for Fermina would still continue over many long years, thus showing how much he was in love with her. Over the years Ariza would do many things to attempt to woo Fermina back into his arms, none that would prosper. All of the acts he committed, he committed for the love he had for her. Most of the actions she would never know of, for he would never show nor tell her about such things. It seemed almost daily Marquez had Ariza writing Fermina a poem, a song or some sort of letter. Most which would never make it into her hands. Florentino Ariza’s love for Fermina Daza went beyond just loving her. He was truly IN love with her. People can love many people, but I believe that there can truly only be one person you are IN love with. Ariza would sacrifice so much throughout his life to attempt to have her attention. He would quit jobs, and move to be near her or to even just see her for a split second, like he would do when he went to the park to see her walk past. Ariza would finally work hard and become prosperous and wealthy, again trying to impress Fermina. Ariza’s love went beyond the childish love that most of us have endured. He waited fifty-one years to be with the woman that he considered his soul mate. This truly shows a great deal of self-determination and love for another human.

The New Negro by Alain Locke

The essay The New Negro by Alain Locke’s defines what Locke believes to be the â€Å"Old Negro and the â€Å"New Negro. This paper will compare and contrasts Marcus Garvey The Future as I See it and Langston Hughes various poems on why Locke would have characterized them as either Old Negroes, New Negroes, or both. I believe Locke, Garvey , Hughes were determined to see Blacks succeed. Each writer expresses their idea in their own unique way, but they all wanted freedom, equality, and respect. For example, Locke would characterize Garvey as the Old and New Negro.For instance, Garvey writes that it’s time for each person to decide on how they will discover freedom. Garvey writes â€Å"The hour has now struck for the individual Negro as well as the entire race to decide the course that will be pursued in the interest of our own liberty†. (p. 1000) Garvey was writing his views on the future as he saw it. He wanted blacks to know now it’s your time to decide which path you want to take and you have the freedom to do so. Also, Locke writes â€Å"The Negro today is inevitably moving forward under the control largely of his own objectives†. (p. 89) Blacks are achieving their goals because ‘ is something they desired on their own. Also, Garvey informs the Negro that their will be people who will try to discourage you from reaching the freedom you so desperately want. Garvey writes, â€Å" Some trying to capitalize the new spirit that has come to the Negro to make profit out of it to their own selfish benefit; some are trying to set back the Negro from seeing the hope of own liberty†¦ â€Å"(p. 1001). In spite of, what the white men might think or feel on how far Negros will get in life, we must not listen and believe what they feel.Garvey writes â€Å"white men may laugh at the idea of Negroes talking about government; but let me tell you there is going to be a government†¦Ã¢â‚¬  (p. 1002) Garvey writes to the Ne w Negroes that we can’t let anyone plant a seed in our minds and our spirit that we can not achieve the same goals that the white man wants. This is a new day for us and we are going to embrace this new beginning and let no one stop us for achieving our goals. In addition, Garvey writes to the New Negroes about the vision he sees for them.He reminds them that God created them and because of this you are special and do not allow anyone to tell you differently. Garvey writes, â€Å"Remember that you are men, that God created you Lords of this creation. Nonetheless, Garvey’s vision for Negroes was that we can do anything that we set our minds to regardless of the circumstances that we could face. Garvey writes, â€Å" Let no man pull you down, let no man destroy your ambition, because man is but your companion, your equal; man is your brother; he is not your lord; he is not your sovereign master†. p. 1003) Garvey’s vision to the Negroes was that man is not the one you live for, God is the one who will be their with you to the end and he will never leave you. Also, Locke would characterize Hughes poems as New and Old Negroes. First, in Hughes’s poem Mother to Son; a mother is telling her son that her journey through life has not been easy, but she will not give up. Hughes writes â€Å" Life for me ain’t been no crystal stair. † (p. 1292) This mother is telling her son her life has not been easy but she is still standing.The mother wanted her son to know no matter how hard times may become don’t you give up. Hughes writes â€Å"So boy, don’t you turn back. † Locke and Hughes both were sending the same message; they both were determined to see blacks succeed. Next, Hughes poem I Too relates to a young black man who believes that he is beautiful and one day everybody will notice this. â€Å"They send me to eat in the kitchen When company comes, But I laugh, And eat well, And grow strong. † (p. 295) The young man will go quietly and he will dream about the day when he will be able to sit at the table with everybody and they will notice he is a beautiful person. Hughes writes â€Å"Tomorrow, I’ll be at the table When company comes. Nobody†ll dare Say to me, â€Å"Eat in the kitchen,† Also, in the Theme for English B by Hughes I believe Locke would have characterized this to the New Negro. It was about a young color-man who was only colored student in his English class. His instructor asked the class go home and write something that is true and it will let you know who you really are.The young color boy wanted his instructor to know that even though they both might not want to be part of each other world, they both could learn from each other. I believe Locke, Garvey, and Hughes all shared similar values and views about the New Negro and Old Negro. All of them told their stories in different ways, but they all told their in own unique way. Finally, a ll three authors wanted to express how they believed that we can reach our goals regardless of any obstacles that may stand in our way. Sharise Williams Literature-125 Professor Crowe.

buy custom Military Changes Then and Now essay Introduction To some several Americans, they have known only one part of life; being part of the military. Generations of male family members and now females have been moving from one base to another being part of the armed forces. These men and women have protected the country during times of unrest. Different changes have been effected in the military over the years. This paper will examine the military history from then and now. The changes Todays military is of course very different from that of our great grandfathers and those who came before them. Presently, there are greater options for the military members unlike in the past. The advancements come in such areas as education, the decision to allow women to hold combat positions, allowing black women to serve in the military, private sector employment. The state of housing for the military has also changed. There have been several changes throughout in terms of housing. The military housing sector has I fact advanced in great leaps and bounds. The old days barracks have been replaced with modern accommodations. These modern units are full featured installations with a sports arena and other recreational opportunities on the ground. They also contain family support areas like those in education, medicine, and counseling (Adams, G). History of the Battle Dress Uniform The Battle Dress Uniform otherwise known in short as the BDU has been used by the military and from 1981 to 2005 has been the same. Initially there were two types of the BDU which were designed for hot weather and the other for temperate weather. The hot weather type had a coat and a pant made up of 100 percent cottn while for temperate made of a nylon and cotton blend. These uniforms were criticized for easy fraying. They were later replaced in 1996 with an enhanced hot weather BDU. With constant ongoing research, better BDUs have been created. Modern BDUs for example use a dye that prevents detection from NIIC (Near Infrared Image Converters) which helps soldiers to avoid detection by allowing them to blend with the surrounding (Kelly, E). Over the years, the military has embraced several changes on recruitment of members to the service. Then, it was so controversial to integrate blacks into military. Things have changed so fast that now black women have, although it is a work in progress, these women can now and largely serve in the military alongside the men. And also for the first time recently, the first female submariners are now training, a great obstacle they have overcome which was unthinkable of in the past. Then the official policy of the US military since the civil war was to keep the white and Negro races segregated. In fact Negro soldiers were assigned to Negro units as they were regarded as being unsuitable for combat. But now the situation is different as even the commander in chief is a black, President Obama who is the US president. (Time CNN). The military has thus earned a reputation as a meritocracy where minorities as well as women can flourish. Another change is the repeal of the DADT policy otherwise better known as the dont ask dont tell policy. Gays and lesbians now serve openly in the military. This is a new social challenge that has not been there. In 1993, President Bill Clinton signed the US military dont ask dont tell policy that prohibited anyone demonstrate(s) a propensity or intent to engage in homosexual acts" from serving in the armed forces because "it would create an unacceptable risk to the high standards of morale, good order and discipline, and unit cohesion that are the essence of military capability." (Johnson, R.). The DADT policy banned all military lesbian, gay and bisexual members from openly serving in the military. A bill was later introduced into the house and repealing the DADT. In December 2010, the bill was passed and now all these diverse sexual oriented groups can now openly serve in the military (Religious tolerance). Last but not least we examine the military satellite communications, then and now. According to Mak King, the Military satellite communications have become so essential that the military have to use them during combats. In the past though, satellite communications was not as important as it is today. But over the years, there has been increased demand for capacity and this has called for improved satellite designs. New improved satellite communications have been developed to combat higher level crimes and this has been possible with technology advancements over the years (King, M. and Riccio, M.). Conclusion Over the years, the phase of the military has undergone leaps and bounds to change its face and its operations. Several aspects have changed over time and this include; their housing units and standards, allowing minorities and women to serve in the military and even higher ranks, lifting of the DADT which now allows gays and lesbians to serve openly in the military and last but not least is the improvement of communications tools used to combat crime and this has been made possible thanks to technology advancements. Of special interest is also the BDUs which have been changed to prevent detection from NIIC (Near Infrared Image Converters. Buy custom Military Changes Then and Now essay

Organic memory transistor Essay Example | Topics and Well Written Essays - 750 words

Organic memory transistor - Essay Example They (Fakher & Mabrooka, 2012) reported that the output characteristics for both the devices show perfect and good saturation area at low and high voltage; VDS respectively. They also found out that, in the control device, the mobility (Â µ), the threshold and the on/off rotation were 0.27cm2 V-1S-1, 16V and 4.1 X 104 respectively. However, in the organic memory floating gate; the mobility was found to be 0.04 cm2 V-1S-1, the threshold was between -23 and -47 volts while the on/off ratio was 2.3 X 103. For high mobility and increasing on/off ratio, the smooth surface, uniform and loose pin holes where the reverse proportionality of PMMA concentration which was above 15wt%, and can be a significant influence on the average grain region and average roughness of pentacene layer. They also stated that a clear trend was there to show that there was no hysteresis in the control transistor due to non charge storage element. In addition, they said that the gold floating gate of the organic memory transistor causes low mobility due to the gold nanoparticle affected to follow and carry charges from the first layer of PMMA through gold floating gate to the second layer of the PMMA in the insulator. ... That was when different pulses of OTMFTs were applied to the gate electrodes. This was evident in non-volatile state attitude for the organic thin film memory transistor device. Graphene oxide and floating gate: Other authors, including Tae-Wook Kim, Yan Gao, Orb Action, Hin-Lap, Hong Ma and others, also reported about the electrical characteristics of organic non-volatile memory transistors (ONVMTs) using chemically synthesized grapheme oxide (GO) as a charge trapping layer based on pentacene/PMMA/Grapheme oxide nanosheets/SiO2.GO (Kim, et al., 2010). the nanosheets were produced by modified Hammer’s process then deposited on top of SiO2 substrate using spin coating and hot plate (3000 rpm for 40s and 120C0 for 10 minutes), respectively. The drain/source contact was of gold and had a thickness of 50nm thick and a semiconductor layer of 50nm was deposited using thermal evaporation of pentacene. The GO nonosheets were located between PMMA and SiO2 layers of about 10nm of thickn ess. A clear trend, morphological properties of grapheme oxide such as rougher and coverage region were dependent on the concentration of its solution. The output and transfer characteristics of both the devices, namely; control (OFETs) device without grapheme nanosheets and (ONVMTs) device within GO nanosheets, have similar values of mobility ), threshold and on/off ration which were 0.16 cm2V-1S-1, 6.5V and 106 respectively. On the other hand, travelling electrons or hole from pentacene to GO nanosheets through PMMA layer resulted to hysteresis which was featured in the transfer characteristics of (ONVMT) device. However, there was no hysteresis in the control (OFET) due to the absence of the trap charge

William Hill portfolio diligence Essay Example | Topics and Well Written Essays - 7500 words - 1

William Hill portfolio diligence - Essay Example Purpose, findings, and research questions that will guide the study are generated from the shareholders’ effects and the motives for acquisition. The data for this study will be the secondary data from Journal of Financial Economics. In the background study, I analyse the reasons for William Hill’s takeover and stipulate the post-takeover performance of the company. Motives for acquisition of Stanley Leisure and shareholders’ value are critiqued in the following project. In this project, I have used the capital assets pricing model (CAPM) in methodological analysis and OLS Regression for data sources. I can resolve if William’s merger was worthwhile through liquidity-based explanations. Mergers and acquisitions involve the amalgamation of two or more firms or the purchase directed to current firm within the foreign country. This was established by Whiting (1976) that acquisitions are effected through capital transfer, use of marketing skills, and presence of skill for management to increase the efficiency of the companies concerned. The development of better information systems in the global trade can enable a company increase its level of performance and meet its customer needs better. I will discuss in detail the research questions that will assist William Hill in acquisition of Stanley Leisure; due diligence need by William Hill is to enable the shareholders with adequate concept of underlying William acquisition portfolio than the prevailing market allocation of betting services.
