Prison Inmates, Are Some Of The Most Maladjusted People In Essays
Prison inmates, are some of the most "maladjusted" people in society. Most of the inmates have had too little discipline or too much, come from broken homes, and have no self-esteem. They are very insecure and are "at war with themselves as well as with society" (Szumski 20). Most inmates did not learn moral values or learn to follow everyday norms. Also, when most lawbreakers are labeled criminals they enter the phase of secondary deviance. They will admit they are criminals or believe it when they enter the phase of secondary deviance (Doob 171). Next, some believe that if we want to rehabilitate criminals we must do more than just send them to prison. For instance, we could give them a chance to acquire job skills; which will improve the chances that inmates will become productive citizens upon release. The programs must aim to change those who want to change. Those who are taught to produce useful goods and to be productive are "likely to develop the self-esteem essential to a normal, integrated personality" (Szumski 21). This kind of program would provide skills and habits and "replace the sense of hopelessness" that many inmates have (Szumski 21). Moreover, another technique used to rehabilitate criminals is counseling. There is two types of counseling in general, individual and group counseling. Individual counseling is much more costly than group counseling. The aim of group counseling is to develop positive peer pressure that will influence its members. One idea in many sociology text is that group problem-solving has definite advantages over individual problem-solving. The idea is that a wider variety of solutions can be derived by drawing from the experience of several people with different backgrounds. Also one individuals problem might have already been solved by another group member and can be suggested. Often if a peer proposes a solution it carries more weight than if the counselor were to suggest it (Bennett 20-24). Further, in sociology, one of the major theories of delinquency is differential association (Cressey 1955). This means some people learned their ways from "undesirable" people who they were forced to be in association with and that this association "warps" their thinking and social attitudes. "Group counseling, group interaction, and other kinds of group activities can provide a corrective, positive experience that might help to offset the earlier delinquent association" (Bennett 25). However, it is said that group counseling can do little to destroy the power of labeling (Bennett 26). The differential-association theory emphasizes that a person is more likely to become a criminal if the people who have the greatest influence upon them are criminals (Doob 169). Most of today's correctional institutions lack the ability and programs to rehabilitate the criminals of America. One can predict that a prisoner held for two, four, eight or ten years, then released, still with no educationling, there is disadvantages. For instance, members of the group might not be as open or show emotion because they want to appear "tough." Also the members might not express their opinions openly because the others might see it as "snitching." For the group to work it takes a dedicated counselor (Bennett 22-23). Another type of correctional center used for rehabilitation is halfway houses. Halfway houses are usually located in residential communities and are aimed to keep offenders in the community. The name comes from the fact that they are "halfway between the community and the prison" (Fox 60). The "rationale" behind halfway houses is that criminal activity originates in the community, so the community has a responsibility to try to correct it. Also, sending a person who has deviant behavior and who has been associated with criminal influences, to prison would just make the problem worse (Fox 61). "The best place for treatment is in the community; this prevents the breaking of all constructive social ties" (Fox 61). Programs in halfway houses usually involve work release or study release and group sessions for therapy and counseling. Most programs vary greatly depending on the administrator. Generally, the purpose is to "reintegrate" members back into the community. There are three systems generally used in programs and in the process: "change by compliance, client-centered change, and change by credibility in that it 'makes sense." (Fox 73). The compliance model is designed to make good work habits. The client-centered model focuses on a high understanding of the person. The credibility model emphasizes making decisions and getting back into the community. These programs are made to avoid institutions as much as possible (Fox 73). On the other hand, many inmates think the government does not want to rehabilitate criminals. The reason behind this thinking is that prisons

The Significance of Fish in Chinese Language
The Significance of Fish in Chinese Language Learning the word for fish in Chinese can be a highly useful skill. From ordering seafood at a restaurant to understanding why there are so many fish themed decorations during Chinese New Years, knowing how to say fish in Chinese is both practical and an insight into cultural values. Deconstructing the Chinese word for fish includes learning about pronunciation and its evolution from pictograph to a simplified character. The Chinese Character for Fishà The Chinese character forà fish,à written in the traditional form, is é Å¡.à The simplified form isà é ± ¼. Regardless of what form it is written in, the word for fish in Chinese is pronounced like you. Compared to English, the Chinese yà º has a shorter, more relaxed ending, dropping the exaggerated w sound that rounds out the big, full vowel in you. Evolution of the Chinese Character for Fish The traditional form of the Chinese character for fish evolved from an ancient pictograph. In its earliest form,à the word for fish clearly showed the fins, eyes, and scales of a fish. The current traditional form incorporates the four strokes of the fire radical, which looks like this (ç ¬).Perhaps this addition suggests that fish is most useful to human beings when it is cooked.à Radical This character is also a traditional radical, meaning that the primary graphical component of the character is used as a building block in other, more complex Chinese characters. Radicals, also sometimes called classifiers, ultimately become a shared graphical component for several characters. Thus, the Chinese dictionary is often organized by radical. Many complex characters share the radical that derives from fish. Surprisingly, a lot of them are not related to fish or seafood at all. Here are some of the most common examples of Chinese characters with a fish radical. Traditional Characters Simplified Characters Pinyin English å⦠«Ã¥ ¸ ¶Ã© Å¡ å⦠«Ã¥ ¸ ¦Ã© ± ¼ bà di yà º octopus é ®âé Å¡ é ² é ± ¼ bo yà º abalone æ â¢Ã© Å¡ æ â¢Ã© ± ¼ bÃâ yà º to catch fish çââé ·Ã© Å¡ çââé ± ¿Ã© ± ¼ chÃŽo yà ³u yà º to be fired é⡠£Ã© Å¡ éââé ± ¼ dio yà º to go fishing é ± ·Ã© Å¡ é ³âé ± ¼ à ¨ yà º alligator; crocodile é ® é Å¡ é ® é ± ¼ guà « yà º salmon éâ¡âé Å¡ éâ¡âé ± ¼ jà «n yà º goldfish é ¯ ¨Ã© Å¡ é ² ¸Ã© ± ¼ jà «ng yà º whale é ¯Å é Å¡ é ² ¨Ã© ± ¼ shà yà º shark é šå ¤ « é ± ¼Ã¥ ¤ « yà º fÃ

This phonetic similarity has led to fish becoming a symbol ofà abundance and prosperity in Chinese culture. As such, fish are a common symbol in Chinese art and literature, and they are particularly important in Chinese mythology.à For instance, Asian carp (as they are known in the U.S.), are the subject of many Chinese lyrics and stories. The character for this creature is é ² ¤ é ± ¼, pronounced là yà º. Pictures and depictions of fish are also a common decoration for Chinese New Year. Fish in Chinese Mythology One of the most interesting Chinese myths about fish is the idea that a carp that climbs the waterfall on the Yellow River (known as the Dragon Gate) transforms into a dragon. The dragon is another important symbol in Chinese culture. In reality, each spring, carp gather in great numbers in the pool at the base of the waterfall, but very few actually make the climb. It has become a common saying in China that a student facing examinations is like a carp attempting to leap the Dragon Gate. The dragon/carp relationship is referenced in popular culture in other countries through the Pokà ©mon Magikarp and Gyarados.

Criminal Law (Advise Katarina, Paula, and Jenny as to their potential Essay
Criminal Law (Advise Katarina, Paula, and Jenny as to their potential liability for homicide) - Essay Example There are three ways of commissioning homicide a) killing with motive where one may have the chance of partial defence b) gross negligent conduct causing death and c) dangerous harm that culminates to death (Ashworth 2006). In scenario ââ¬Å"aâ⬠referred to as above, is a "voluntary manslaughter". The remaining attempts fall within the ambit of ââ¬Å"involuntary manslaughterâ⬠. Mens Rea The intention of crime falls within the definition of Mens rea that deals with the state of mind of a defendant at the time of committing a crime to determine criminal liability. In order to fix the responsibility of crimes of a defendant, mens rea at the time of committing crimes is essential under the criminal act. In other words, motives refer to the reason that compelled the defendant to commit criminal act. Take the examples of Fred and Wilma whose matrimonial relationship last for about twenty years. Later on, Fred began to suspect that his wife was having sexual affairs with Barney, which made him enraged. He bought gun and shot her to death. The case under reference indicates criminal act of Wilma and the intent of Fred to kill her. The motive was very clear (Ormerod 2011). It is to be noted that only motive is not enough to attack a criminal. Other supportive evidences are also required to establish a case against the defendant. Contrary to that, public prosecutor proves that the motive of the defendant was to kill. Therefore, it is not necessary to prove criminal liability.... ves the motive and not the mens rea, there is a strong chance that the defendant must be acquitted by the competent court of law, no matter how bad is the intention. Further if a public prosecutor proves the mens rea with the actus reus, the defendant will not escape from conviction, no matter how noble his motive is (Ormerod 2011). In this respect you may please refer to the cases of Hyam vs DPP (1975), R v Ried (1992), State v. Asher (Ark. 1888). Actus Reus The other way round, actus reusà in accordance with the broader definition of criminal lawà comprises all ingredients of a crime other than the state of mind of a criminal.à In a nutshell,à actus reusà may have the following components a)à conduct b) outcome c) state of affairs and d) omission (Loveless 2012). Here we may refer to the cases of R v Miller (1982), R v Adams [1957], Devlin J, Armstrong, R v [1989] Owen J and Cox, R và (1992) Winchester Crown Court, Ognall J. Coincidence of Actus Reus and Mens Rea A th orough study of Criminal Law: Theory and Doctrine (2010) of Simester and R. Sullivan revealed that according to general rule, the actus reus and mens rea of a crime may have coincidence in terms of behavioural and circumstantial elements with regard to actus reus, which occur at the same time thus satisfying the requirements of mens rea (Simester et al 2010). Potential Liability Holder We have analyzed the whole situation on the mentioned parameters of homicide, which makes Katarina, responsible for the murder of Victor. Her motive for murdering her married boyfriend speaks of ââ¬Å"jealous personality syndromeâ⬠. Because said boyfriend refused to spend the night with her since he selected another girlfriend Audrey for having a sexual pleasure in the night. Katrina felt insulted and made up her mind to

Class 6340 week 6 discussion Assignment Example | Topics and Well Written Essays - 250 words
Class 6340 week 6 discussion - Assignment Example With an increase in the number of nurses with doctorate degrees, the quality of healthcare will improve immensely as they will not only offer more specialized treatment but also implement the nursing care and strategies that has been researched by the nurses with Masters and PhDs. My passion is to interact one on one with the patients and offer direct highly specialized treatment to them. This requires high educational level of expertise in various diseases and this I can get through obtaining a DNP and moving to be a specialist in any nursing location that is related to patient care. Other than that, I will be independent when offering the clinical services which provide more experience and freedom (Billings and Halstead, 2012). An increase in clinical experts other than all crowding into research field is a way to directly improve quality of the healthcare system and also prevent deaths of patients whose diagnosis requires a more knowledgeable nurse than a registered nurse. Having more DNPs who are independent brings about more creativity and room for brainstorming of new treatment plan for the patients. The negative effect of encouraging people to become DNPs is the market flooding with experts than the number of patients requiring such technical expertise. This therefore in the end will lead to redundancy and the quality of healthcare will reduce again in the end (Institute of Medicine, 2010). In order to bring optimal results, AACN needs to regulate the number of schools offering the DNP program and hence limiting the number of students that will graduate as DNPs and hence preventing an overflow in the market and too many independent nurses.

Marketing Nike Essay Example for Free
Marketing Nike Essay Growing up there was one brand that all professional athletes used in my eyes, Nike. The Swoosh, was the icon that all kids had to have, and why not? All the big time players not only had it, but endorsed it. Ads, which had Michael ââ¬Å"Airâ⬠Jordan, Bo Jackson, or Wayne Gretsky ââ¬Å"The Great Oneâ⬠doing amazing physical feats, always, motivated the crowds. The Nike company new this, and blasted it marketing campaign through all sorts of media. In this essay I will break down this multi-billion dollar companyââ¬â¢s marketing techniques in the areas of: customer value, promotional items, marketingââ¬â¢s four pââ¬â¢s of the marketing mix, the segmentation, targeting, and positioning (STP) approach to market the product, Customer Relationship Management (CRM), environmental trends, the largest customer base, its competitors, and ethical marketing for this corporation both stateside and overseas. Putting these athletes in the ads is just one way to build value for a company. From Ashford universities ââ¬Å"Principle of Marketingâ⬠by ââ¬Å"Sara Whiteâ⬠We are introduced to marketing with the definition of marketing as ââ¬Å"an activity designed to stimulate exchanges that have value for customers, partners, and society at largeâ⬠. With this definition of marketing intact the question that still is out pondering is what is value? ââ¬Å"Value was defined as the perceived trade-off between benefits and the sacrifice required to take possession of those benefitsâ⬠. To break it down further we will look at customer value. Customer value is a title for the cost of a particular trade for the purchaser (buyer) instead of the company (seller). Looking into a selling Nike abroad, whatever a customer may pay in the United States may not be the same overseas. The first thing is to look at is how the current client group influences the market in the states. Nike had a humble start with creators Bill Bowerman and Phil Knight trying to improve on the track shoe of the day. The former ââ¬Å"Blue Ribbon Sports Companyâ⬠now known as Nike wanted to increase value into their product by having athletes endorses it. So they found the person that they thought would be the best at building future customer value, Steve Prefontaine. During his college time he never lost a race on his home track, and was exposed to national notoriety with is fourth place finish in Munich. This was one of their first successes in marketing. As popularity for their product rose the selected new sports models to display the shoes on the track. This really kicked of the sale of the shoes. Seeing how this success worked at their home setting, taking it to other countries should be no problem. Paving the way with athletes that had above average ability in their field was how Nike struck the marketing campaigned. Finding someone in another country that could spark the same influence over the masses would keep thing on track for Customer value overseas. This would all depend on what country we planned on taken our product to. The last thing that we are going to look at with customer value is the four utilities of customer value. The four utilities are: Form, Time, Place, and Ease of Possession. The form in the four utilities shows what effort Nike puts into their product that makes it desirable. Part of this desire is the quality and showmanship they place in every item. The other part is who they put in their invention. This was very clear in the mid-80 when Nike was the company that took on NBA rookie Michael Jordan, to represent their companyââ¬â¢s goals. Being one of the leaders of in business, time is important. Nike put their product out when they need to. They also change it enough to keep things fresh. Time also goes along with place. Not only does the timing of releasing product play a huge role, the place does as well. Lastly, ease of possession is just that, how easy will it be to get the product. Included in this is can I get my item fixed or replaced easily also. With internet available in almost everyoneââ¬â¢s pocket from smartphones to tablets getting Nikeââ¬â¢s items have become very accessible. With ease of possession we have to look at what trends are working or not, so that we may fix them. Understanding these four utilities just scratches the surface of what we need to know. To be more in-depth with a strategy we must look at the targeting and market mix portion of promoting. In order to utilize the four utilities properly we must look at the STP approach of marketing. This Approach involves segmentation, targeting, and positioning looks at what a byer values. ââ¬Å"Segmentation can be defined as the process of splitting a market into smaller groups with similar product needs or identifiable characteristics, for the purpose of selecting appropriate target markets. Targeting (or target market selection) refers to: An organizationââ¬â¢s proactive selection of a suitable market segment (or segments) with the intention of heavily focusing the firmââ¬â¢s marketing offers and activities towards this group of related consumers. And positioning (which is sometimes referred to as product positioning) is: Positioning is the target marketââ¬â¢s perception of the productââ¬â¢s key benefits and features, relative to the offerings of competitive products. â⬠With the number of competitors only the rise it is important for an organization to forecast what the consumers buying trends are. Nike, although one of the largest establishments in their field, they still are not untouchable. They have to stay a success by continually improving on the products. Nike leads the way with new technology that innovate all sports. In the late 80ââ¬â¢s the introduction of Nike air did this well. Again they launched a promotional campaign that introduced a series of ads by Bo Jackson one of the top athletes at the time. They saw the future of what their clients wanted, Air. It was the first shoe out on the market with air in the sole. Following the marketing targeting set at this point propelled them ahead of their competitors. To stay ahead of the game the implementation of the four Pââ¬â¢s is the next tool to evolve business plan. The four Pââ¬â¢s that come from the widely used ââ¬Å"marketing mixâ⬠developed in the 60ââ¬â¢s includes production, price, place and promotion. ââ¬Å"Product: The combination of tangible goods, services, and beliefs offered at a specific price. â⬠To stay on the breaking edge of athletic gear with rivals on your heels they have to produce a ââ¬Å"productâ⬠that reaches the masses. The creations did just that, they made it tangible for all with a specific price. ââ¬Å"Price: The amount of money or other consideration a customer must exchange for the offering. â⬠Nikes merchandise because it was ahead of others cost a little more. At the same time they could justify their cost due to the fact the merchandise operated better than anyone elseââ¬â¢s. ââ¬Å"Place: The strategy by which a company gets the right goods in the right quantity to the right place. â⬠Because Phil and Bill both had roots on the west coast mainly Oregon, this is where the perfect place to offer the product out of was. Now, a global sensation you can get it from any corner of the world. ââ¬Å"Promotion: The advertising and selling activity a company undertakes to create demand for the offering . â⬠The only real way to endorse this type of product is to show the benefits in different people that use it. This not only sums up the four Pââ¬â¢s but gives examples of how it applies to this enterprise. While putting all of these aspects together there has to be a way to track certain trends to be more productive. This can be done by customer relationship management or CRM system. CRM is a good tool to utilize once your product has hit the market. This system tracks the companiesââ¬â¢ relationship with the purchaser. The data collected will be from sale and overall marketing . Some items that might be pulled from this information are demographics of the individual buying an item. This is so important to direct and promote ads to those that will actually be utilizing them. When I got my first pair of Nike shoes I was stoked. They were everything that I wanted and more. I was fast to show them to my friends. At that point I would have done anything that Nike asked me to (I was a typical kid). Inside the box was a card and at the time I did not understand what it for. It had questions on it like race, age, sports that I played in at school levelâ⬠¦etc. This was there way of finding out who is buying their goods. Some places will add in rewards or freebies to get their customer feedback. This information can also give feedback on when to promote certain items so that there will be a larger return. Now that all the information is being tracked and fixed, we can now see how it does abroad. In the 90ââ¬â¢s Nike wanted to figure out how to reach an even larger fan base. Soccer was the ticket to gain that popularity not only in one country but almost every country in the world. At the point of taking production to another country the process of building customer value and marketing kind of starts over. Knowing this Nike took players from the World Cup-winning Brazilian National team. They redesigned the uniforms and pulled in some US teams as well . This organization could go a little farther by endorsing other sports as well. One of the most important things about going into other countries with this appeal line is to see what effects it has on the area. From ââ¬Å"Principles of Marketingâ⬠by ââ¬Å"Whiteâ⬠there are a couple of things that affect the marketing environment. The acts that affect the environment are actors and forces . They both exist in two different categories Micro environment and Macro environment. In Micro-environment actors are individuals like: stockholders, board members, competitors, public, and customers . In this category there are also forces which include: Strategic moves by, competitors, Channel partners, Changes in consumer behavior . Macro- environment deals actors with leaders in Culture/society, Politic, Economics, Technology development, Finance and Law . Forces in Macro-environment are; globalization, Technology and media . Letââ¬â¢s see how this looks with Nike. If Nike is to be a success in other countries they have to know how they are going to affect the environment where they go. They also need to know how other countries can affect them. An example of this would be in the Middle East females are not treated as equals. Therefore it would not be a good idea to start up only female sporting lines there. Another example of how they could be affected by the environment is the culture is different that the US, some countries that would use their product cannot afford American prices. This would cause a new marketing scheme. A good place to start is checking the CRM to see what trends these cultures prefer. So currently who is Nikeââ¬â¢s biggest byer? Nike hits such a wide range of sports, from their start in track, to sponsoring golfer Eldrick ââ¬Å"Tigerâ⬠Woods. Almost every sport today has some kind of influence from Nike. The largest in todayââ¬â¢s market is probably the NFL. The National football league has just signed up Nike to create some new gear for this 2012 ââ¬â 2013 season. The great thing about Nike is it now has sister labels that produce more than just athletic products. ââ¬Å"A significant event in Cole Haanââ¬â¢s timelines happened in 1988 when Nike acquired Cole Haan . Thence, international flagship stores and more outlets opened making the reach to influence the use of quality and fashionable footwear become broader and wider . â⬠ââ¬Å"Then the technology of Nike Air was incorporated in the design of womenââ¬â¢s shoes which made a mark on Cole Haanââ¬â¢s emphasis on providing comfort and protection not only for men but also for women. This was the first at that time and the demand for Cole Haan shoes continued to rise . â⬠Nike seems to be unstoppable but they are only a small percentage of the market. There are so many different shoe companies out there today. If an individual can get it in the States they can get overseas via the internet. A few brands that compete with Nike are: Reebok, Adidas, Asics, and New balance. But they are not close to the company that distributes to over 170 countries. Unfortunately although Nike from the stand point of business is a great company they have a dark side also. Ethics is gaining power in the business world. People are tired of seeing cooperationââ¬â¢s destroy morale of the world and marketing is no different. There is a responsibility to the public to give honest communications and things that are not going further corrupt children mind. A lot of marketers will play to childrenââ¬â¢s weaknesses. Rebecca Clay wrote an article on advertising to children. The article goes on to explain that childrenââ¬â¢s psyches are not to the level to decipher fact from fiction. This weakness is exploded and ads well over load kids with ideas of toys and games that they do not need nor should they have. One case of unethical marketing goes deeper than what we can see. It was what was going on behind the curtains. According toâ⬠Mail Onlineâ⬠that put out an article on Nike, about the treatment in the converse factory . They continue on to say that the employees are under paid, making around 50 cents an hour. Terminology such as; dog or pig from supervisors are thrown around in a derogatory way. This is a decade after Nike came under fire for their child labor seat shops in Indonesia. Should something be done to this marketing tycoon? Some kind of apology should come to the public not only in America but to the world. This is part of their obligation to the society has a whole. As kids we can be drawn into many different that catch our attention. Mine, like many juveniles was following the dream of growing up to become a professional athlete. It was the lifestyle at the time that seemed effort less. Nike open my eyes to this more than probably any other brand. The sloganâ⬠Just do Itâ⬠was what I needed to pursue my goals. For a while it felt as though they were not just talking about sports but life who knows maybe they are. Whatever it may be there marketing plan from the start of the back of a trunk; to multibillion dollar cooperation is one of the best. Going through the marketing world with Nike we covered the following: customer value, promotional items, marketingââ¬â¢s four pââ¬â¢s of the marketing mix, the segmentation, targeting, and positioning (STP) approach to market the product, Customer Relationship Management (CRM), environmental trends, the largest customer base, its competitors, and ethical marketing for this corporation both stateside and overseas.

Applications of Prisms and Math :: Mathematics
Missing Figures Prisms and their Applications Introduction A prism is one or several blocks of glass, through which light passes and refracts and reflects off its straight surfaces. Prisms are used in two fundamentally different ways. One is changing the orientation, location, etc. of an image or its parts, and another is dispersing light as in a refractometers and spectrographic equipment. This project will only deal with the first use. Consider an image projected onto a screen with parallel rays of light, as opposed to an image formed by the same rays that are passed through a cubic prism (assume that the amount of light that is reflected is negligible). The rays that pass through the prism will not be refracted since the angle of refraction = sin-1(sin(0)/n) = 0, or reflected, so the images will be exactly the same. More generally, if the rays enter and leave a prism at right angles (Assuming the rays only travels through one medium while passing through the prism), the only effect on the image will be the reflection of the rays off of its surfaces. Since the law of reflection I= -Iââ¬â¢ (Angle of incidence equals the negative of the angle of reflection) is not effected by the medium, the effect of the prism will be same as that of reflective surfaces or mirrors placed in the same location as the reflective surfaces of the prism. It follows that to understand prisms it is important to understand how mirrors can be used to change the direction of rays. Mirror Location Problem 1: Consider the following example: A horizontal ray is required to undergo a 45à º-angle change and this has to be achieved using a mirror. We need to find how the mirror should be oriented to achieve the desired change of angle. Solution: Recall the Snellââ¬â¢s law which deals with refraction: sinI0 /n0 = sinI1/n1 if we define the incoming and outgoing rays ray and the normal of the refractive surface as vectors and using a property of the cross-product we can say the following Q0xM1 = |Q0||M1| sinI0 = sinI0 and also Q1xM1 = |Q1||M1| sinI1 = sinI1 thus N0 (Q0xM1)= n1 (Q1xM1) If we introduce two new vectors S0 and S1 and let them equal n0 Q0 and n1Q1 respectively we will get S0x M1 = S1xM1 or (S1-S0)xM1 = 0 this implies that (S1-S0) are parallel or anti-parallel, which means that we can define a new variable Ãâ which is called the astigmatic constant with S1 ââ¬â S0 = ÃâM1 How is useful for solving our problem?

Mirror Location Problem 1: Consider the following example: A horizontal ray is required to undergo a 45à º-angle change and this has to be achieved using a mirror. We need to find how the mirror should be oriented to achieve the desired change of angle. Solution: Recall the Snellââ¬â¢s law which deals with refraction: sinI0 /n0 = sinI1/n1 if we define the incoming and outgoing rays ray and the normal of the refractive surface as vectors and using a property of the cross-product we can say the following Q0xM1 = |Q0||M1| sinI0 = sinI0 and also Q1xM1 = |Q1||M1| sinI1 = sinI1 thus N0 (Q0xM1)= n1 (Q1xM1) If we introduce two new vectors S0 and S1 and let them equal n0 Q0 and n1Q1 respectively we will get S0x M1 = S1xM1 or (S1-S0)xM1 = 0 this implies that (S1-S0) are parallel or anti-parallel, which means that we can define a new variable Ãâ which is called the astigmatic constant with S1 ââ¬â S0 = ÃâM1 How is useful for solving our problem?

Vacant Chapter 11 Time
I drive and can't help that my emotions are all over the place. I'm angry because I've been living in exile from the oneâ⬠¦ The one person who gives a shit whether I live or dieâ⬠¦ I left her alone to fend for herself. I take my rage out on the steering wheel before pulling over; I need a minute to collect myself. Two minutes. Fiveâ⬠¦ It takes me half an hour before I'm calm enough to continue driving, but I rush because I want to get back to her. I want to touch her, be with her. I realize how fundamentally wrong I've been about my feelings for her. While I thought I was doing what was best for Emily, I never considered that I was really just protecting myself. I hadn't taken her feelings into account. I hadn't thought about what I was doing to her by leavingâ⬠¦and in the same accord, making her declaration of love, trivial. The anger fades and misery takes its place. I'm sad because I miss her. I need her more than air. I need air, and I need Emily. Air is so much easier. Before long, fear sets in. What if she isn't there when I get back? Why would she be? I left her by herself for six days after I swore I'd take care of her. I think about what I did as I continue down the lonely stretch of highway. I worked so hard to separate myself from the drama and emotions of everyday life realizing I haven't been living at all. I think of all the time I've wasted; all the time I could have been with her ââ¬â been with herâ⬠¦ Her legs are bare and slender. I imagine what's just beyond the small rectangle of terry cloth. Her hair tickles the tops of her breasts, teasing me with what's just beyond the knot of the towel. One small flick and she'd be naked before me, her body as fantastic as I've always imagined. My foot pushes a little harder on the accelerator as my frustration builds. I'm tired and feeling the effects of driving ten hours straight. As I consider pulling over, the guilt seeps in again. I've already been away from her for too long. I can't stand to be apart from Emily any longer, but the seconds continue to tick by and I can't seem to get there fast enough. I push on, despite being a danger to others on the road due to my exhaustion. I see a gas station ahead, and force myself off the road and into the brightly lit convenience store. After hours of lonesome interstate travel, the intense glow of the fluorescent lights hurts my eyes, and only serves to remind me of the dim nature of my existence without Emily. I make quick work of refueling the car and myself and then rejoin the blacktop. Finally, finally, I see the mile marker indicating my journey is almost over, an hour to go before I'm back with Emily. Anxiety weighs heavily on me because I think I could have gotten here faster; what if she just left? What if she's been waiting for the last week and that was her limit? I shouldn't have left in the first place. I should have told her how I felt so we could be living a happily ever after. Regret won't change things, though. It doesn't serve any purpose now. I pass the city limits sign, and a smile spreads across my face. I'm happy and hopeful. A hundred and one scenarios play out in my head as to how Emily will react when she sees me. She throws open the screen door and rushes towards me. I catch her in my arms and spin her around. I tell her I love her and want to spend eternity with her. She smiles and says she wants the same thingâ⬠¦ We barely make it to the bedroom before I fully make her mineâ⬠¦ I open the door and call her name but no one answers. All her things are gone, and she's nowhere to be foundâ⬠¦ As I make my way up the walk, she stops me and tells me she doesn't ever want to see me again. That I broke her heart and I'm a fuck-up she wants nothing to do withâ⬠¦ I'm brought out of my thoughts as a car horn blares behind me. Dawn has broken and there is slight traffic moving about. I'm not sure how long I've been sitting at the stop sign on the corner before the car behind me demands attention. It's now or never, and never isn't an option. I stand at the door, my door ââ¬â her door ââ¬â ready to knock. It occurs to me how odd this is; I'm about to knock on my own door. Suddenly, I'm embarrassed. I look down and my clothes are dirty and unkempt. I smell ââ¬â it's been two days since I've cleaned up at all. How can I look her in the eye, kiss her lips, hug her body, when I look and smell like a homeless man? I am homeless, though. Without her, without her love and care and warm eyes, I'm a man with a heart that has no home. So I knock.
