Properties of Light free essay sample

A drop of isopropyl alcohol will absorb light energy of different colors, and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits (from previous lab) * Pipette (or eyedropper) * Rubbing alcohol Index card * 9-volt battery * Flashlight * Stopwatch * Small cardboard box (shoe box) Procedures: A three-sided enclosure from the cardboard box was made. This created a location for applying light from the LED to the drop of alcohol while minimizing the effect of air currents on the evaporation rate. The eyedropper was used to place a single drop of isopropyl alcohol on an index card within the enclosure. The same size drop was used each time the step was repeated. The time it takes for the drop to evaporate without the LED present was recorded. The dark spot on the card caused by the alcohol was no longer visible.

The evaporation time was recorded. The same procedure was repeated for the different colored LEDs over the alcohol drop. The current through each LED and the distance from the LED to the drop of alcohol was the same for each run. The procedure for each color of LED was repeated at least 10 times and an average time of evaporation for each color was calculated. A graph of evaporation time versus frequency of the LED was then made. The red light has a lower energy than the violet light that’s at the end of the spectrum. The frequency of the light increases as the color of the light changes from red to violet. Wavelength and frequency are inversely proportional, which causes the wavelength to decrease as the color changes from red to violet (Hewitt, pg. 520). Depending on the color of the light, the wavelength can range from 710-5 cm (red) to 410-5 cm (violet), but all electromagnetic radiation travels at the speed of light. The frequency of the light, which is the number of wavelengths per seconds is calculated using the equation C=LN. L is the wavelength, N is the frequency, and C is the speed of light (Library Thinking Quest). From the observations collected, the red LED light took the longest to dry the drop of alcohol and the blue dried it the fastest. Since the red light is on the lower end of the electromagnetic spectrum is used the lowest amount of energy. Just by looking at the brightness of the light, this conclusion was made but reassured after doing some research. The red light was very dim and faint compared to the brightness of the green and the blue. The blue was the brightest of the lights. This light used the most energy and is one of the farthest on the spectrum beside violet. Since the frequency of light increases as the color of light moves down the spectrum, the red light has the smallest frequency of 4. 2*10-14, green has middle frequency of 5. 66*10-14 and blue has the largest frequency of 6. 37*10-14. The frequency is directly proportional to the energy produced by each of the light, which is shown in the graph above. The blue light had the highest frequency and that used the most ener gy. The red LED used the least amount of energy because it had the lowest frequency. The greater the frequency caused the alcohol to dry faster since it used more heat (energy) at one time. Light energy and frequency are directly related in the real world also. Typically since red lights have less energy than blues lights, blue objects are said to be hotter. In 1923, American astronomer Edwin Hubble (1889-1953) made an astounding discovery. As Hubble observed, the light waves from distant galaxies are shifted to the red end, and he reasoned that this must mean those galaxies are moving away from the Milky Way. These observations concluded that something that showed red was moving away from its observer. The laws of thermodynamics state that where heat is involved, the movement is always away from an area of high temperature and toward an area of low temperature. Heated molecules that reflect red light are areas that are moving toward an area of low temperature. Molecules of low temperature reflect bluish or purple light because the tendency of heat is to move toward them. Fire, for example, it lets off heat to keep people warm. The color of fire is mostly red and orange. These colors are at the lower end of the spectrum of light. The reason why fire is the color red is because; red gives off the lowest amount of energy because it has the lowest frequency. Fire can be used in many different ways in the world without using mass amount of energy to heat things up. As mentioned in the lab from last week, the alligator clips caused a lot of issues with holing the connections together. A better material would be the connection covers where the wires go inside a little tube and are squeezed together at each end to insure security.

Essay on Art as Experience

Essay on Art as Experience Essay on Art as Experience Essay on Art as ExperienceThe term â€Å"art† can be defined as the conscious and effective use of individuals’ talents, such as skills and creative imagination to produce impressive aesthetic objects.   Since the development and growth of human society, individuals make attempts to enhance their live with various forms of art, e.g. architecture, painting, photography and sculpture. However, there is hardly anybody has used his/her imagination to reflect personal experience of being some form of art. Today, art reflect human experience and helps to explore spiritual subject matters. According to John Dewey, â€Å"experience occurs continuously, because the interaction of live creature and environing conditions is involved in the very process of living†(36).   The major goal of this paper is to reflect personal experience of some actions and art forms, including the experience of looking in the mirror for 15 minutes, the experience of being a painting, the exp erience of being a style of painting, the experience of a photograph and the experience of viewing oneself in advertising. Different forms of experience, e.g. the experience of being a painting, a photograph and an advertisement, reflect different feelings because of certain differences between these images. The differences between images described in personal experiences reflect various values.My experience of looking in the mirror for 15 minutes  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Studying my face in the mirror for at least fifteen minutes was not an easy task. I timed myself and managed to stare for the entire fifteen minutes. I studied myself with the same honesty as Rembrandt or Van Gogh did. I study myself candidly. For the last five minutes, I stroke several different intentional poses. My experience of looking in the mirror for 15 minutes is amazing. I see different facial expressions, which reflect my mood and my personality. When I smile, my facial expression is li ght and appealing to the audience. When I am sad, my facial expression is dark and gloomy. I can easily change my facial expression if I start thinking about something positive or negative. I can find some similarities in analysis of Rembrandt’s image, Van Gogh’s image and my own image. I have found that the experience of looking in the mirror for 15 minutes is a valuable tool to increase self-esteem because an individual has an opportunity to highly value one’s own personality.My experience of being a paintingIf I were a painting, I would be in several periods of art history, e.g. Postmodernism (1970- ) if my painting reflects positive mood, or Modernism (e.g. Abstract Expressionism, 1940-1960) if my painting reflects negative mood. These art historical periods reflect my changeable personality. Postmodernism can be viewed as a break from modernism. This art period has some features of modernism, but these features provide more positive views. The following asp ects refer to Postmodernism: the individual’s position in the context, the increased role of aesthetic pluralism and meaning of art. My painting would imply culturally, politically and socially. First, my painting would reflect cultural context because culture plays an important role in art. Cultural attitudes toward a work of art explore an individual’s personality. On the other hand, cultural identity of the nation is formed by art. Besides, my painting would imply politically because I would include some political signs or symbols to make it more appealing to political viewed of the audience. Moreover, my painting would imply socially because each element in my painting must be focused on social acceptance. Abstract Expressionism is the highest form of Modernism. I believe that my painting can have some characteristics of Abstract Expressionism, if it is presented in a negative context, e.g. individuality, creativity, unconscious style of representation, the element s of visual formalism. These characteristics are focused on creating the feeling of pure abstraction.Experience of being a style of paintingIf I were a style of painting, I would be landscape. I believe that landscape is a unique style of painting because it reflects the beauty of nature. Landscapes demonstrate poetry in nature, placing emphasis on the intimate expression of various forms of nature. In some way, these forms reflect human emotions. I would be landscape of mountains and waterfall.   I believe that the landscape I would be should include many elements of nature in order to allow the viewer to enjoy the spiritual journey of bold imagination.   Being landscape means make the views feel the beauty of nature, and developing positive emotions and feelings.Experience of being a photographIf you were a photograph, it would be romantic style of photography that provides an idealized vision of photography. It would be some peaceful location, soft light colors, some storytel ling context and impressive images. The lighting would be intense. It is known that â€Å"the intensity of the illumination within the light envelope determines how the final image will look† (Rand 94). The photograph would be impressive if some subjects need more light and can reflect light. Among the most talented photographers, Brian Smith would influence my image. Smith’s advice would help to make a really meaningful and adorable portrait. My photograph would imply culturally, politically and socially. First, it would reflect American culture. Besides, it would be meaningful from a political perspective. It would reflect some symbols of American politics to encourage the audience highly value the U.S. political system and its leaders. Moreover, my photograph would imply socially because it would be socially acceptable.Experience of viewing myself in advertisingI can honestly view myself differently from how advertising presents how I should look.   I can identify what influences me emotionally. I can not only regulate my emotions, but also understand the feelings of other people. I am influenced emotionally by inequality, injustice, violence towards women and children, and violence towards animals.   In most cases, physical events have a strong influence on what I feel emotionally. For example, I hate racism and racial discrimination. I criticize those advertisements that have some hint of racism.I can articulate what influences me in an advertisement. I can be influenced by the effectiveness of humor, beauty, strength, self-confidence, tolerance and endurance.   Advertisements have powerful effects on people. However, advertisements influence people without their full recognition that they are being influenced. I can separate what makes me feel good about myself from what advertising indicates should make me feel good about myself. Although I know that advertisement often influences people in undesirable ways, the positive advertisemen t is more effective than a negative one. I feel good about myself from positive effects of advertisements.   From a psychological point of view, my feelings are reflected in what advertising indicates should make me feel good about myself.Richard Prince’s description of the Perfect Tense in Chapter 12 does not describe me, because I fall into Thomas Frank’s counterculture rebellion.   I believe that Thomas Frank’s study play an important role in revealing the existing links between advertising and the counterculture. It has been found that the possible consequence of the counterculture would be rebellious consumer behavior. According to Thomas Frank, cultural rebellion is associated with the counterculture. Counterculture attracts attention of many people today. I feel that I am a part of all of it. I believe that I feel myself somewhere in the context of cultural jamming. Culture jamming stands for the so-called politics of representation, which involves ad vertising in the context of artistic satire. I feel that I can act as culture jamming refiguring various product images in order to raise public awareness of existing problems (environmental problems, or unequal and unjust social practices). I do not fall on the â€Å"Advertising Horizon†.Moreover, I feel capable of constructing an identity outside the parameters of the advertising market. Today the advertising market provides some parameters, which help to successfully read and value some objects, or services, or oneself.   In other words, it sets some limits on human appreciation of an object or service. These limits help to construct the so-called brand identity. I can use my personal attitudes, experience and knowledge to construct an identity that would not be a standard. My identity would not be focused on the parameters of the advertising market. I would create a new form of advertising. I can support this fact by the ability to express my own ideas and desires to ac hieve the established goals in advertising.The cultural myths of individualism (the autonomous individual) or love of technology influence my self-image to a great extent. I accept individualism as the key cultural myth. I criticize collectivism because the effects of collectivism may be negative in establishing one’s own identity. I believe that personal self-realization is the basis of one’s own self-image. Besides, love of technology may influence my self-image, making it more appealing to the audience and more effective in interpretation. I completely agree that technology influences the way we think about ourselves, as well as the way others think about ourselves. I feel myself as being a victim of bipolar thinking. In some cases, I feel that bipolar thinking is caused by complex mental processes that may lead to emotional ride of extreme highs as well as deep depressive lows.ConclusionThus, comparing my painting, photograph and advertisement, it is necessary to c onclude that there are many differences between these images. These differences reflect the values we have studied all semester because the experience of viewing myself in advertising differs from the experience of being a photograph, or a style of painting, or painting. I feel that the most important information I learned in this class is how to develop the so-called visual literacy, or the ability to â€Å"read† and interpret the images that can be found in our information society. I have found that visual arts are important cultural element that the mass media use to obtain the power of representation.

Steinbeck's depiction of the struggle of Agricultural workers during Essay

Steinbeck's depiction of the struggle of Agricultural workers during the Depression, his role as a social commentator, and its impact upon his work - Essay Example The novels also serve the purpose of a social documentary and present a picture of the prevailing systemic injustices in the United States. It is fashionable with the new breed of novelists to separate politics from art. But in the case of John Steinbeck, this distinction is not evident. The author, in the process of creating a work of art had also taken upon himself to ask questions of social injustices in general and economic disparities in particular. Hence, Steinbeck’s body of work are in essence are full of his own perspective on the state of rural American society; the medium of the novel have given Steinbeck the requisite scope and opportunity to fulfill his role as a social commentator. The rest of the essay will cite instances from the two novels as well as foray into the biographical aspects of the author himself to support this assertion. To understand this social activist trait in Steinbeck’s character one has to look at the experiences and circumstances that shaped his vision of America. Firstly, his years as an adolescent in Salinas, where he got a first hand experience of his parents’ struggle for survival is a formative influence. It is the next phase of his life however, that will prove more important – his long-time relationship with the radical social worker Carol Henning. The influence of Carol Henning cannot be underestimated, for her socialist views on life had clearly rubbed off on Steinbeck, which is evident from the earliest journalistic assignments that Steinbeck undertook. His years as a novice journalist also had a key role in the shaping of his character, for these early writing assignments were the foundations for his later literary pursuits. In both the works in discussion – The Grapes of Wrath and Of Mice and Men, the influences of these formative stages of his early l ife are quite obvious. While Steinbeck never really espoused a

Religious Liberty in Public Schools Essay Example | Topics and Well Written Essays - 500 words

Religious Liberty in Public Schools - Essay Example It goes a long way in eliminating discrimination on the basis of religion in public places. This is what informed the decision in Van Orden v Perry (2005), where the Supreme Court held that the Ten Commandment on the government monument at the Texas State Capitol violated the Establishment Clause of the First Amendment.  The issue of religious expression in public places, especially in schools, is an area that has attracted a series of serious debates. Many of these matters always find their way in court. In the case of Abington School District v. Schempp (1963), the state of Pennsylvania required that ten verses should be read from the Holy Bible each morning in public schools each school day. The majority of Supreme Court judges found this to contravene the First Amendment.  Just as in the above-mentioned case, it would be wrong to display the student’s depiction of Jesus Christ in class as this would be going against the First Amendment as that would amount to leaning t owards Christianity as opposed to the required neutrality in the public schools towards religion (Ackerman, 2001).  Putting all these factors into consideration, it would therefore go against some student’s rights, as this is a captive audience, and can be easily swayed into believing something that is against their religious creed. It is therefore important not to display that kind of work in class to protect the constitutional rights of the other students and avoid violating the First Amendment, which could have in itself dire consequences.

Personal Action Plan Assignment Example | Topics and Well Written Essays - 1000 words

Personal Action Plan - Assignment Example In developing a personal action plan, you will look at your personal strengths and weaknesses and your ability to think strategically, and you will identify the goals you want to achieve. Answer the following questions to help you prepare for your action plan. My greatest strengths include ability to work in a team and making things run smoothly. My ability to work in a team, as supported by Mosser and Begun (2013) has helped me appreciate what other players in the group are bringing to the table. For this reason, any activities we do as a team is more effective as each and every player has a role to play. My obsession with ensuring things run smoothly has enabled me to complete assignments on time and also deliver error free work. Achieving positive results in assignments depends on individual ability to comprehend and follow instructions. In some instances, my assignments have not met the standards and requirements set forth by the facilitator hence submitting substandard work. Therefore, I need to try to understand assignments a lot better and making certain that I do the right assignments. To achieve this, it would be imperative for me to reread the instructions in an effort to ascertain that I am doing the right assignment, and also revise my work after completion (Kongstvedt, 2007). I have definitely gained accomplished the ability to strategize and think critically in the course of this program. In terms of critical thinking, the obstacles I have faced have forced me to analyze difficult situations dispassionately and subsequently congregate data and other relevant information from all available sources in order to make an informed decision in terms of addressing the problem. In terms of strategizing, I learnt to set my personal objectives in line with the available opportunities. For instance, my objective to become a doctor was based on the available opportunities i.e. the need to improve the health status of the

Cost Benefit Analysis Economics Essay

Cost Benefit Analysis Economics Essay Introduction Cost Benefit Analysis (CBA) is a technique which seeks to bring greater objectivity into the decision making. It is a well known evaluation technique that is extensively engaged by both public and private organisations to support the decision making process. It can be useful to almost any kind of decision in any kind of field. It is helpful to identify all the relevant benefits and costs of a particular scheme and to quantify them in monetary terms. The practice arrived in the United Kingdom in 1960s for use in the transportation sector. CBA techniques were extended to cover a wide range of applications, such as water resource management, motorways, nationalized industries, airport locations, forestry, recreational facilities and a wide range of urban investment projects (Paul, 2000). Private sector, direct monetary costs and benefits determines the profitability and increases the output and investment. All costs and benefits in public sector, affected by an investment must be evaluated in some other way. Welfare economics helps to resolve such issues as how to assess costs and benefits of a non-monetary environment how to assess the community benefits when no charge made for public facility and how to fiddle with the market failure. Cost Benefit Analysis CBA rests on the recognition of a potential Pareto development. The basis for this is the proposition that, a decision is justified if those who benefit from it could compensate by those who lose by it. Compensation needs not really occur. What is essential is that the expenses of a policy to those who suffer the costs are exceeded by the value that beneficiaries place on it. This may still remain on an adequate basis for judgment because CBA attempts to ascertain whether the resources are being used efficiently. It will often be the case that the occurrence of costs and benefits, i.e. who bears them, will moreover be very important. CBA may provide a framework designed to identify accurately where the costs and benefits fall, so that a political judgement may be completed as to their satisfactoriness. CBA is a widely used technique which evaluates public spending and aims to avoid inappropriate distribution of public resources. In theory, it helps public decision-makers to invest only in the projects that create more profitability from the viewpoint of the community. To function perfectly, the CBA procedure needs to be engaged prior to the decision is made, so that the potential of the range of project proposals can be compared and evaluated. It aims to evaluate the set of direct and indirect effects of a project, its financial and non- financial effects on the set of economic agents concerned with the investment. These effects are then synthesized, after monetary evaluation, to assure a socio-economic balance which establishes the return on the investment, with this return being estimated on the basis of specific indicators (Auzannet, 1997). According to Boardman et al. (2006) the major steps in CBA are as follows; Specify the set of alternative projects Decide whose benefits and cost count Catalogue the impacts and select measurement indicators Predict the impacts quantitatively over the life of the project Monetize (attach dollar values to) all impacts Discount benefits and costs to obtain present values Perform sensitivity analysis Make a recommendation History and Uses of CBA At present, CBA is being used in both government and international organization. While certain concepts of the technique oriented from Europe in 1840s, the use of CBA in environmental economics is relatively a new incidence which is becoming recognized after regulations were set by the US government. And this made the use of CBA compulsory in the 1930s (E.J. Mishan and Euston, 2007). It was used to generate a solution toward the problems of water provision. After World War II, there was pressure towards the efficiency in government and the search was on for ways to make sure that the public funds were efficiently utilised in major public investments. This resulted in the beginnings of the fusion of the new welfare economics, which was essentially a Cost-Benefit Analysis and practical decision-making. This particular process arrived in the United Kingdom in 1960s in support of the transportation sector. It was applied to the construction of M1 motorway and the Victoria line on the und erground (Economic Labour Market Review, December 2008). In recent years, it is recognised as the major appraisal technique for public investments and public policy. Principles of CBA There are eight basic principles under this CBA ((S.L. Kirama, 2010). These are; There must be a common unit of measurement CBA valuations should represent consumers or producers valuations as revealed by their actual behaviour. Benefits are usually measured by market choices Some measurements of benefits require the valuation of human life The analysis of project should involve a with or without comparison CBA involves particular study area Double counting of benefits or costs must be avoided Decision criteria projects Emergence of CBA CBA allows different projects to be ranked according to highest expected net gains in social wellbeing. This gives important limitations of government spending. The main stages in CBA approaches are (Geoff Riley, 2006), Calculation of social costs and benefits. This includes direct costs, indirect costs and the benefits Sensitivity analysis of event occurring Discounting the future value of benefits Comparing the costs and benefits Comparing the net rate of benefits The Application of CBA In the private sector, financial CBA is used to justify equipment and technology investment, measure life cycle costs, meet regulations cost-effectively and quantify hidden costs and intangible benefits. It is also useful to demonstrate how outsourcing and leasing can result in cost savings and how quality improvements can affect returns. Social CBA is being used to evaluate the social merit of projects or policies. In practice CBA vary between countries and sectors within countries. The main differences include the types of impacts that are being included as costs and benefits within the assessment procedure. This is an extent to which the impacts are expressed in monetary terms and difference in discount rate between countries. The public CBA may also vary from private CBA (S.L. Kirama, 2010). CBA is likely to have its main usage within the public sector where (J. Harve and E. Jowsey, 2004); Price signals are insufficient to guide investment decisions Spill-over benefits and costs are important owing to the magnitude of the schemes The wellbeing of unborn generations has to be allowed Key Concepts in CBA There are some key concepts in CBA. There are; present value, discount rates, opportunity costs, cost and benefits, discounting, net present value, shadow prices, etc. (J. Harve and E. Jowsey, 2004). Government Decision- making Government may take the form of regulation such as building regulation to reduce fire hazards, taxes or subsides or providing goods and services. The main difficulty in many public-sectors is that the goods are provided free of charge or below the market price. So they are forced to focus on short-term special effects of the financial system and the long-standing sustainability of the public finances. Government decisions depend on subjective political considerations. For example, obtaining a social mix council housing may be providing an expensive residential area. However, public investments have serious defects. The one-man, one-vote principle does not weight votes according to the intensity of welfare gain or lost. Therefore, majority of the decision allow two voters marginally in favour of a scheme to outvote one who strongly opposes it in spite of the fact that the sum of their benefits is less than the costs impose on the single opponent. Political decisions are important one-sided. Economic efficiency in resource allocation requires that objective criteria should be used as far as it is feasible. The extension of government involvement in the economy has increased the weight and complexity of decisions which needs to be made at government level. Many argument says that decentralisation of decision-making is desirable. Application to Construction Industry Government is basically responsible for roads, bridges, airports, parks, amenity land, new urban areas and housing. CBA is normally being favoured by many transportation economists. It assesses the entire benefits and costs associated with highway project, including both capital and user costs. In this case, project requires less cost but provides more benefits right through the analysis period which are chosen first. CBA estimates the costs in monetary terms. Traditionally, a benefit-cost ratio, net present value or internal rate of return is being used. Recent research suggests that the net present value (NPV) may provide the best project selection measure if the transportation program is under financial constraints (Reed and Rutherford, 1997). The Use of Cost-Benefit Analysis in Transportation Sector Transportation policy and scheduling decisions often engage tradeoffs between conflicting objectives. Most highway cost allocation and investment evaluation studies are primarily concerned with direct market costs, such as road construction and maintenance, travel time, vehicle operating costs and crash damages. These vary depending on vehicle type and roadway conditions. They assume that the total amount of vehicle travel does not change, so were unconcerned with vehicle ownership and parking costs. Other types of studies incorporate environmental impacts, primarily air pollution, but sometimes it also includes noise and water pollution, and various other categories of land usage impact. Some studies have only considered external costs avoiding the internal ones. CBA is extensively used within the transportation segment. CBA of transportation investment projects tend to neglect long-term environmental consequences and needs among the community group with a low ability to pay. It has been emerged as one of the most used tools in deciding the viability of proposed infrastructure projects. The predictions regarding the impact of such projects are often problematic uncertain. The transport modelling tools are used in order to estimate positive as well as the negative impacts. Case Study Heathrow Terminal 5 In this case, the British Airport Authority (BAA) planning to build terminal 5 the cost is approximately around  £4 billion. Planning application was submitted in February 1993 (Heathrow T5, October 2005). They were considering the following benefits, such as Economic growth: Demand for air travel in south-east England is forecasted to be doubled in the next 20 years, making the expansion seems to be essential within the Air travel industry. This in turn might create thousands of jobs and businesses depending on the Heathrow airport expansion in order to provide sufficient supply capacity to meet the growing demand. An increase in the capacity of Heathrow will make maximum usage of airports existing infrastructure and land. The economy and trade: if it does not meet demand, UK will lose its airlines and foreign investments within the other European regions. The benefits of a world-beating industry would be reduced. Therefore, many sectors of our aviation industry will have a comparative advantage and might add huge sums to our balance of payments. Jobs: This project will create job opportunities which are estimated to be around 16,500. And it may also create 6,000 construction jobs during the building phase. This will have multiplier effects on the local / regional and national economy. Transport: The terminal will be the centre of a world-class transport exchange, with new Tube and rail links. Car traffic would rise only slightly. The social costs of increased traffic congestion have been exaggerated by the environmentalists. Environment: The site which has been allocated for terminal 5 is currently a disused sludge works. And any displace wildlife and plant life will be carefully relocated. The noise climate around Heathrow Airport has been improving for many years, even despite the fact that the number of aircraft movements has increased considerably partly due to the phasing out of older, nosier aircraft. Noise and night flight: BAA promises no increase in overall noise levels or in night flights. The number of flights will be increased by 8%. (Source: http://tutor2u.net/economics/revision-notes/a2-micro-cost-benefit-analysis.html) Objections are being raised against this project but those were not enough to refuse the planning permission. Conclusion CBA provides a rational technique for the evaluation of projects where market information is either non-existent or deficient. But it should not make false claims for objectivity by dealing in precise sums. However it is helpful for decision-making purposes, it is not an alternative for it. Further, CBA is potentially a useful aid towards planning decisions and it does not avoid the need to make value judgements in the evaluation of intangible arising from different projects. The overall conclusions are to be drawn from the assessment of costs and benefits. However, such value judgements are made clear in the evaluation decision making process.

Red Badge Of Courage :: essays research papers

Article Review on "Red Badge of Courage" The book Red Badge of Courage, is about a physical and emotional pain that a solider of the Civil War might of went through. The soldiers pain comes from all of the horrible things associated with war. The main character, Henery Fleming, joins the Union army dreaming of the heroic things he will accomplish. During the war he discovers that war is not so great and becomes real unsure of himself. Henry then meets up with his friend Jim Then halfway through the book he confronts his cowardice and gains a realistic and sense of duty and responsibility. When the novel ends he has conquered his fear. Then Henry meets Wilson, the loud solider, who I think represents the two sides of human nature. Wilson is a mean and tough guy that no one likes and then towards the end of the book he finds that he really cares about Henry. While Henry is dealing with all of his emotions they are moving into war. The book Red Badge of Courage is insightful because it gives great detail about the hardship of war, the physical and emotional side of it. It shows how a young solider of the Civil War would have felt and also it shows all his fears. It is not just about war and the fighting, the book gives details about the camp and the other soldiers that Henry Flemmings interacts with. Stephen Crane has a unique writing style because it is very symbolic and it paints a lot of pictures for you. Crane is very imaginative and takes a look from one viewpoint into an isolated person and his relationship with society. I believe the book was well writing at times because some parts could have used more detail. It would have been easier to understand. Some parts of the book I felt like I was really there but others it just felt so distance. This work is important because of its historical value that it has with the Civil War. It tells not just about the war itself and what is going on but the emotion al side of a young solider. It tells how soldiers break down in war and that all of them are heroes at sometime in the war. I learned from the book that you must face your fears and that if you run from them once then the next time you must face them.
