Position entirely your own about what 'college level writing' should look like or what criteria students should have to be succe - Essay Example College level writing would be identified from its structure. Ideally, the student should give the plan of the writing in the first paragraph, and then followed by supporting paragraphs to be summarized in the final paragraph. The thesis statement should appear in the introductory paragraph, giving an indication of what the writing entails. In supporting the main idea in the writing, the writer should borrow from other sources. No writer holds all the information needed and should therefore consult other credible sources. Lunsford (n.d.) supports this argument noting that an integration of a great deal of other sources into a piece of writing shows the analytical aspect of a writer and the ability of such a writer to think at a higher level. Individual paragraphs adopt a similar structure, having introductory, explaining and concluding sentences. However, scientists and art students could argue against this structure, giving examples of writings of project reports and poems. They wou ld argue that writing could adopt any structure as long as it communicates the intended information effectively. Even with this approach, the basic structure would still have to apply where the writer begins with an introduction, indicating the objectives of the writing, then follows with a supporting body before giving a conclusion. To come up with a coherent piece of writing, editing plays a major role. As Lunsford (n.d.) noted, editing eliminates spelling, grammar and punctuation mistakes. This makes the writing understandable to the reader. Content in college level writing is highly regarded. As noted, college students have grown in writing and should therefore be able to impart knowledge through their writing. Having gone through primary education and then to high school, such students should have been exposed to a lot of writing tasks. From the mistakes made and the aspects that rewarded more, the students should have learnt the requirements for an effective writing. At the co llege level, the writers would be expected to think in addition to writing. Knowledge would only be communicated if the writer succeeds in analyzing and evaluating various texts from which information has been borrowed. As such, I support the argument by Lunsford that a writer at this level should be able to Ã¢â¬Å"bring other voices into the conversationÃ¢â¬ in a way that makes the writing informative (n.d., 184). However, I appreciate those who would argue against the need to borrow from external sources so as to give perfect wiring, such as those in creative and artistic writing. Despite this argument, it would be important to note that such writings have borrowed from external sources whether knowingly or unknowingly. The ability to evaluate these sources, extrapolate and integrate them in the writing produces effective college level writers. College writing should be motivated by the need to fulfill the objectives of the given instructions. Thos of the school of thought of L unsford indicate that writing should be driven by what one believes in. In fact, while analyzing the writing by Ã¢â¬Å"

Memphis Design - Assignment Example Memphis emerged in the winter of 1980 as a consequence of a joint approach by Scottsass, Mendini, Alchymia and Branzi. The development of the Memphis design began between 1977 and 1978. The lamps and the Memphis furniture were the first designs to be established though they were considered inconsistent. Memphis had to improve on the original products, and certain innovative measures had to be established. The innovation of graphics was one of the improvements that were affected by Memphis. Technical drawings, lamp manufacturer development of ceramics, manufacture of fabrics and invention of new plastic covers (Radice 35-37). Memphis reflected on the period it emerged based on the individual designs, materials and the need to develop new approaches. Most of the products and materials at the time did not have a reflection of the period and a change was required to enhance the development of new designs. Memphis has a number of products that are unique and exhibit a number of unique features. The furniture is one of the most favorite products that Memphis produces. The furniture is a favorite because they are manufactured using unique designs that make them stand out from the rest of the materials (Radice 141-145). Consequently, the colors used in chairs give a unique impression to the products. Another favorite product is the lamp that is manufactured in different designs. Unique materials such as metal bars manufacture the design of the lamps. There are different colors used for the lamps that provide a classic illumination to the surrounding space. The bookcase is also a favorite product because it is designed and painted with unique colors that illuminate the different sections effectively providing a classic and a unique outlook to the product. Memphis was successful to a greater extent in its initiatives and products. Memphis through its designs and materials developed a new approach that would

The Optical Time Domain Reflectometer Essay In fiber optic networks, OTDR (Optical Time Domain Reflectometer) is an opto-electronic instrument used to characterize an optical fiber. Unlike power meters OTDR does not measure loss, but instead implies it by looking at the backscatter signature of the fiber. Generally, OTDR are used to determine the loss of any part of a system, the length of the fiber and the distance between any points of interest. Most of the light which is sent to the fiber can be detected at the other end, but a part of it is always absorbed or scattered. Absorption and scattering are caused by imperfections of fiber, small grains of dirt, for instance. Scattering means that light is not absorbed but it is just sent in different angle after it hits small particles in optical fiber (Figure 1). Some of the light is scattered to the direction it came from. This is called backscattering. Backscattering forms the basis to the use of the optical time domain reflectometry. Figure 1 Rayleigh Ã¢â¬âscattering in optical fiber Optical time domain reflectometry is based on scattering and reflections. OTDR sends an optical pulse to the fiber and measures the received backscattering. The signal which is received consists naturally only of scattering and reflections of pulse which was sent. By interpreting signal as a function of time OTDR can draw an attenuation of a fiber as a function of distance. Theory of the OTDR Optical time domain reflectometry measures backscattering as a function of time and graph is then drawn as a function of distance (Figure 2). The graph represents the power of signal which the detector of the OTDR receives. The graph of fiber probed by OTDR consists of two spikes with gradually decreasing line between them. The line between spikes is decreasing because the received signal is decreased as a function of distance in accordance with attenuation coefficient of fiber. At the both ends of fiber reflection is large (Fresnel reflection) which creates spikes to the graph. Length of the fiber can therefore be measured from the width of the graph. Figure 2 OTDR signal as a function of distance An OTDR trace is a graphical representation of optical changes or events on a fiber. An event could be a splice, optical connector, a bend, a break, or just normal backscattered light from the fiber itself. In the OTDR trace faults for instance, are shown as a drop in the power of received signal (Figure 3). Size of a drop depends on an amount of power that is lost due to the component. The lost power represents of course the attenuation of component. Components and faults in fiber are either reflective or nonreflective. Reflective components create a spike to the graph of OTDR the same way as the both ends of fiber do. With nonreflective components there are no spikes because no excess light is reflected back. In most cases reflective attenuation is caused by connectors or other passive components and nonreflective attenuation is usually caused by fusion splice or similar fault in fiber. Figure 3 Attenuation of different faults Figure 4 OTDR Trace Information The slope of the OTDR trace shows the attenuation coefficient of the fiber and is calibrated in dB/km by the OTDR (Figure 4). Whereby, The height of that peak will indicate the amount of reflection at the event, unless it is so large that it saturates the OTDR receiver. Then the peak will have a flat top and tail on the far end, indicating the receiver was overloaded. Sometimes, the loss of a good fusion splice will be too small to be seen by the OTDR. Thats good for the system but can be confusing to the operator. It is very important to know the lengths of all fiber in the network so that the operator is not confused by unusual events. Reflective pulses show the resolution of the OTDR. Two events which are closer than the pulse width cannot be seen. Generally longer pulse widths are used to be able to see farther along the cable plant and narrower pulses are used when high resolution is needed, although it limits the distance the OTDR can see. The Dead Zone Dead zones originate from reflective events (connectors, mechanical splices, etc.) along the link, and they affect the OTDRÃ¢â¬â¢s ability to accurately measure attenuation on shorter links and differentiate closely spaced events, such as connectors in patch panels, etc. When the strong optical reflection from such an event reaches the OTDR, its detection circuit becomes saturated for a specific amount of time (converted to distance in the OTDR) until it recovers and can once again measure backscattering accurately. As a result of this saturation, there is a part of the fiber link following the reflective event that can not be Ã¢â¬Å"seenÃ¢â¬ by the OTDR. Analyzing the dead zone is very important to ensure the whole link is measured. Two types of dead zones are usually specified: 1. Event dead zone: This refers to the minimum distance required for consecutive reflective events to be Ã¢â¬Å"resolvedÃ¢â¬ , i.e., to be differentiated from each other. If a reflective event is within the event dead zone of the preceding event, it will not be detected and measured correctly. Industry standard values range from 0.8 m to 5 m for this specification. Figure 5 Common OTDR with 3 m event dead zone 2. Attenuation dead zone: This refers to the minimum distance required, after a reflective event, for the OTDR to measure a reflective or non-reflective event loss. To measure short links and to characterize or find faults in patchcords and leads, the shortest possible attenuation dead zone is best. Industry standard values range from 3 m to 10 m for this specification. To overcome the problem of dead zones, usually a patchcord of about 100 m is added at the beginning of the system. As a result, all lauch dead zone problems have finished before the fiber (which is to be tested) is reached. Ghosts When testing short cables with highly reflective connectors, it is likely to encounter ghosts like in Figure 6. These are caused by the reflected light from the far end connector reflecting back and forth in the fiber until it is attenuated to the noise level. Ghosts are very confusing, as they seem to be real reflective events like connectors, but will not show any loss. If a reflective event in the trace is found at a point where there is not supposed to be any connection, but the connection from the launch cable to the cable under test is highly reflective, look for ghosts at multiples of the length of the launch cable. Figure 6 OTDR Ghosts Resolution of the OTDR Consider that light travels 1 m every 5 ns in the fiber, so a pulsewidth of 100 ns would extend for a distance of 20 m. When the light reaches an event, such as a connector, the light is reflected. The reflection appears to be a 20 m pulse on the OTDR. However, if two events are separated by a distance of 10 m or less (Figure 7), the two reflections will overlap and join up in returning to the OTDR. Figure 7 Thus the OTDR will display the two events as one event and the loss at each event is not detected, instead the sum of losses at both events will be shown on the OTDR. Choosing a shorter pulsewidth may give a better resolution but in turn resulting a low energy content (causing shorter detection range). Besides using a shorter pulse which will provide the required range, a tool that is called a Ã¢â¬Å"visual fault locatorÃ¢â¬ can help too. The visual fault locator injects a bright red laser light into the fiber to find faults. If there is a high loss, such as a bad splice, connector or tight bend stressing the fiber, the light lost may be visible to the naked eye. This will resolve event which is close to the OTDR or close to another event that are not resolvable to the OTDR. The limitation of this tool is about 4 km.

Affirmative Action Will Build a Strong Nation Affirmative Action: often upon hearing this word, one will start thinking about quotas and reverse discrimination. However, contrary to this misconception, affirmative action is actually a policy that dictates that employers attempt to find diverse employees by exploring untraditional sources of labor. The goal of affirmative action is to create a work force that mirrors the population of the nation both in gender and in ethnicity (Hanmer 8,10). Affirmative action is necessary to give all Americans an opportunity to be successful and to counteract the discrimination that still exists in modern society. Affirmative action is not only morally justifiable, but it is also socially and economically preferable in order to improve our society. The United StatesÃ¢â¬â¢ government first implemented affirmative action to overcome some of the clear differences in living conditions between people of different genders and races. Unfortunately, these differences still exist and eliminating affirm ative action now would be premature for our nation. Affirmative action is essential to compensate for the fact that women and minorities receive fewer opportunities to succeed. Even after laws were passed to end institutionalized racism, the white males who owned the businesses and held the best jobs before continued to own the businesses and hold the best jobs. While legal equality may have been achieved, the nation was nowhere near having true social equality. As President Lyndon B. Johnson stated when he first started affirmative action, Ã¢â¬Å"This is the next and the more profound stage of the battle for civil rights. We seek not just freedom but opportunity.

Dear Stella, I hope this letter finds you well. I am sorry about leaving so abruptly, but I was called away on urgent work. I have been sent to Crythin Gifford by Mr. Bentley to attend the funeral of Mrs. Alice Drablow, I also need to sort though all of her legal documents. Mrs. Drablow lived in a strange little house called Eel Marsh House. To get out to the house you must cross the Nine Lives Causeway, it is only accessible during low tide, otherwise it is covered by water, and impassable. The house is very strange, all on it's own on a small island separated from the rest of the main land. At first I thought it to be quite beautiful but it has a scary if not dark side to it. Even Mrs. Drablow was a bit strange, she lives alone and no one from the village will speak of her. When I arrived Mr. Daily, the local landowner, took me to the Gifford Arms where I have been staying. I went to the funeral of Mrs. Drablow, on the way there I saw some school children and they had strange white pasty faces. When I arrived I noticed that there were very few people there. There was a woman in black clothes with a pasty white face, which I saw on the way back to the village and again on Eel Marsh Island. After the funeral of I went to Eel Marsh house, to start work. Mr. Keckwick took me across the causeway on a horse and trap. When we arrived at Eel Marsh House Keckwick left me and said he would return at five to collect me. I looked around the island; there is an old graveyard with some ruins of a small abbey. The names on the gravestones were all undecipherable because they were covered with various fungi's. While looking around the graveyard I saw the mysterious Woman in Black, a cold feeling came over me like nothing I had ever felt before, but before I could approach her she ducked away under a headstone and disappeared. I don't think you should worry about me I'm fine and I'm not worried about her. She was probably a figment of my imagination; the marsh mist was quite dense. After that went in to the house and I started work opening all the windows, to get some light. I searched thought the rooms to see what was in side the house. It has an old musty smell, all the furniture is old, and made of strong wood. It was about four, so I decided I would walk back to Crythin Gifford, Keckwick wouldn't be back until five and the exercise would be good for me. As I started to walk along the causeway I noticed that it was getting darker and darker and the mist was drawing in, the sea mist was thick and salty. The further I got from the house the better I felt, but soon I couldn't see it any more because of the mist. I thought about turning back but I would soon meet Keckwick and he could take me the rest of the way. The mist was soon playing tricks on my sight and hearing, I could hear a pony and trap coming a long the road to the causeway, and it went silent. I then heard noises of screaming like someone was drowning, I thought this was my imagination, I didn't know how far it was to the other side of the causeway and the water was rising fast so I decided to turn back and head for the house. When I got back I was very worried and I was shaking. I sat down in one of the old musty chairs and had a drink, I must have fallen asleep because when I awoke someone was knocking on the door, when I opened it I saw Keckwick and the pony and trap. They were normal, still alive; it must have been my imagination about him drowning. He apologized for not coming to pick me up but he was unable to because of the sea mist, I was unlucky. I hope that everything in London is fine. There is no need for you to come down to Crythin Gifford, because I should be returning soon, I will go back to Eel Marsh House today and stay for a couple of days to finish all the work and send anything important back to Mr. Bentley. Hope to see you very soon. Yours Lovingly, Arthur

The Golden Ratio Certain pictures, objects, and animals appeal to the human mind more than others. Proportions and images of symmetry often contribute to our fascination with them. Often, when examined carefully, you may find a common Ã¢â¬Å"coincidenceÃ¢â¬ between man made objects and those found naturally in nature. This fluke, however, may be used to ascertain various mathematical relationships between these objects. This paper will introduce the golden ratio and weigh its significance on math, art, and nature. 1.6180339887Ã¢â¬ ¦. has been given many names varying from the Ã¢â¬Å"golden ratioÃ¢â¬ first coined by the Greeks, to the Ã¢â¬Å"golden rectangleÃ¢â¬ and Ã¢â¬Å"golden sectionÃ¢â¬ , Ã¢â¬Å"phiÃ¢â¬ named after Phidias a renowned Greek sculptor, as well as the Ã¢â¬Å"divineÃ¢â¬ ¦show more contentÃ¢â¬ ¦The definitive polymath, he had almost too many gifts, including superlative male beauty, a splendid singing voice, magnificent physique, mathematical excellence, scientific daringÃ¢â¬ ¦ (Beckett, 117) He studied at various places including Milan and Florence and the Vatican. It is in these cities that he became famous. He masterfully uses the golden ratio in the Mona Lisa framing her head as well as the rest of her body parts in exact proportion to the golden rectangle. Furthermore, he goes on in such works as the Vitruvian Man and Virgin and Child with St. Anne to incorporate the golden rectangle into everything he possibly can. He was by no means enthralled in art. Instead, his great passions were mathematics and the natural world, and he compiled volumes of detailed drawings and notes on anatomy, botany, geology, meteorology, architectural design, and mechanics. (Stokstad, 693) Toward the end of his life math, particularly the golden ratio, began to dominate everything he created. Leonardo da Vinci died in 1519. Another painter that used, primarily, golden rectangles was Piet Mondrian. In, Composition with Gray and Light Brown virtually every rectangle has the Ã¢â¬Å"pleasingÃ¢â¬ dimensions.

Sample details Pages: 2 Words: 602 Downloads: 5 Date added: 2019/05/17 Category Society Essay Level High school Tags: Ethical Dilemma Essay Did you like this example? When Chipotle opened its first restaurant in 1993, the idea was simple: show that food served fast didnt have to be a fast-food experience. Chipotles website says that, over 23 years later, our devotion to seeking out the very best ingredients we can remains at the core of our commitment to Food with Integrity (Our Company 2018, 1). However, two E. Coli outbreaks hit Chipotle in 2015, which infected 60 customers. As the FDA was not able to pinpoint the direct cause of this issue, three ethical issues have been identified as the potential causes. The first issue is Chipotles overall concern for ingredient sourcing that are in compliance with FDA standards. In Chipotles2017 annual report, it states that, the Executive Director of Food Safety directs a quality assurance department that establishes and monitors their quality and food safety programs, and works closely with their suppliers to ensure their high standards are met throughout the supply chain (Annual report 2017, 9). The combination of the quality assurance department and food safety programs is the efficient approach which may prevent ingredient sourcing risks. It is important for Chipotle to clarify what they want and what their customers value. Finding the balance between ethical standards and financial intelligence is critical to a companys success. DonÃ¢â¬â¢t waste time! Our writers will create an original "Chipotles Three Ethical Issues" essay for you Create order The second issue is if Chipotle employees are being properly trained to prepare and serve foods in correlation to FDA standards. According to the notes of consolidated financial statements from 2015 to 2017, it declares that, pre-opening costs, including training, rent, wages and other restaurant operating costs, are expensed as incurred prior to a restaurant opening for business, and are included in operating expenses on the consolidated statement of income (Annual report 2017, 52). The annual report shows that pre-opening costs are $16,922,000, $17,162,000 and $12,341,000 separately from 2015 to 2017. However, from these notes, it is hard to tell whether training expense is enough or not for Chipotle. Furthermore, there is no explanation for the decrease of pre-opening costs from 2016 to 2017. In my opinion, it is better to declare expenses in training that has occurred, which will help stakeholders have direct and clear insights into efforts of training that Chipotle has made. The third issue is if the board has performed their responsibilities in corporate governance guidelines. A well-defined and enforced corporate governance provides a structure that, at least in theory, works for the benefit of everyone concerned by ensuring that the enterprise adheres to accepted ethical standards and best practices as well as to formal laws (Rouse 2008, 1). From Chipotles 2017 annual report, Chipotle adopts the Board Performance Self-Evaluation Process to consider whether and how well each committee has performed the responsibilities in its charter and whether the committee members possess the right skills and experience to perform their responsibilities (Annual report 2017, 95). The adoption of this process will help Chipotle keep overseeing the annual operation and committee responsibilities which makes sense for preventing Chipotle from ethical dilemmas in the future. In conclusion, I believe that Chipotle did act unethically in their previous business practices. However, their annual reports from 2015 to 2017 show some improvements and efforts they have made. In order to prevent another E. Coli outbreak, Chipotle must make it a priority to ensure the safety of their foods. In order to fix their ingredient sourcing issue, Chipotle must focus on their quality assurance department and food safety program. To be considered ethical, Chipotle must give their employees the tools to succeed and generate great products. Whats more, the board must continuously perform the responsibilities in corporate 4 governance guidelines. Last but not least, Chipotle must be willing to spend more on food safety, quality assurance and training expenses, and find a better way to realize financial intelligence.
