Proposition 8 - Research Paper Example null and void by the federal courts had created an amendment to the Californias constitution that said that marriages between a man and woman were legal and enforceable by law declaring al same sex marriages as unenforceable. Before its passing, the California states same-sex marriages were protected by right. Despite the affirmation by the Californias supreme courts in May 2008, the legislation went ahead and prepared the proposition. The campaigns around the proposition 8w ere highly contested. The repercussion of the vote, an influential focus on Proposition 8 was sustained with demonstration around the state, country and litigation1. It has a focus on several aspects of the proposal and campaign funding. Three court cases seeking to nullify Proposition 8 were put up just after the election in November. In addition, the California Supreme Court proclaimed it would consider the lawsuits. In May, 2009, the Supreme Court of California upheld the amendment to the constitution2. Proposition 8 is uncomplicated and straightforward. It contained the identical 14 words that were beforehand accepted in 2000 by approximately 61% of votes in California: â€Å"Only marriage between a man and a woman is valid or recognized in California.† The sentiments in the proposition 8 were not first raised in the proposal, they had been earlier raised in the year 2000 where nearly 61 percent of the votes in California in the state. The vote was consequently overturned by a panel of four judges. Further activism sort to redeem the "peoples choice" through a constitutional amendment. The activism sort to "restore the definition of marriage" which was a union between a man and a woman. According to the creators of the proposition, it had an aim of protecting the institution of marriage, but was not an attack towards the gay fraternity. Notable is that the proposition has no intention of infringing on the benefits and rights bestowed on both gays and lesbians who are in domestic union or

Testing of Aggregates Analysis

Testing of Aggregates Analysis Numerous test has been developed that test toughness and abrasion resistance and durability and soundness of aggregates. This report analyses the testing of Aggregates using three Main tests to analyse the degradation of aggregates so best performance is observed in construction, asphalt, concrete or any other field. The aggregates must be abrasion resistant and weather durable to provide good base in pavements for roads. Detailed description of these tests is provided with their respective results. The results are then examined to see which of the following three test are more accurate to check the durability and abrasion of the rocks. Based on the Laboratory results and the Literature reviews, Los Angeles Abrasion test results are used more than others. Although most of the DOTs and construction companies use all three test prior to use of the materials. Soundness test has poor repeatability so it is often not considered as primary test. This research was conducted at Englobe Corp laboratory located in Dartmouth, Nova Scotia. It was performed under the direction of Mr. Mark Downie. The laboratory supervision was provided by Mr. Daniel McMorran. The quality of the aggregates in the construction materials, asphalt concrete is determined by various tests out of which Los Angeles, Micro Deval and Soundness are most widely used in construction industry. Los Angles Abrasion test and Micro Deval test involve the spinning of aggregates in a close vessel where there are spun in a medium of water or air. The vessel is filled with contact charges (Iron sphere) for a specific amount of time. The analysis of particle degradation using mechanical test can be classified in two class, fragmentation and wearing. The sample that has more wide range of grain size ( e.g. 1250 gm of ) indicates fragmentation and has a well graded distribution curve whereas the sample that has poor range of grain size( 5000gm ofà ¢Ã¢â€š ¬Ã‚ ¦) indicates wearing with a bad graded distribution curve. Soundness test involves testing the durability of the aggregates using sodium sulphate or magnesium sulphate solution. Samples of different grain sizes are washed and dried and kept in salt solution for 16 hours and then kept in oven to dry. This cycle is repeated for seven days and then the sample is weighed to see the loss of sample. This test usually received poor rating for its inconsistent repeatability and correlations. Standard Testing methods Los Angeles Abrasion Test AASHTO T96 ( ASTM C131) Micro Deval Test AASHTO T327 (ASTM D6928) Sodium and Magnesium Sulfate Soundness AASHTO T 104 (ASTM C88) As Per American Standard of Testing Materials following pass-fail criteria were used: LA abrasion: Passed if loss à ¢Ã¢â‚¬ °Ã‚ ¤ 40% Micro Deval: Passed if loss à ¢Ã¢â‚¬ °Ã‚ ¤ 18% Sodium Sulphate Soundness: Passed if à ¢Ã¢â‚¬ °Ã‚ ¤12% If the aggregates passed the above criteria, then they are durable.   Los Angeles Abrasion test involves the test to measure the degradation of the aggregates by creating actions like impact, abrasion, grinding and constant wear and tear inside a rotating steel drum. The steel drum spins for a specific time with a specific number of steel balls of specific weight to create an abrasion of aggregates. The number of steel balls and the amount of aggregates put in the steel drum depend upon the grading of the test sample. The steel sphere carries the aggregates and the steel balls creating a grinding effect and then drops it to the other side making a crushing effect. This cycle is repeated again and after certain number of revolution the sample is sieved too see the amount retained from the degradation and too see the percentage loss. Apparatus Los Angeles Machine with wall thickness of at least 12mm. The inside diameter should be 711 ±5mm and the length of 508 ±5mm. The rotating drum should be closed from all ends and should be set at a rotating speed of 30 ±3 rpm. ( ASTM C131) Sieve with 1.7mm (No.12) passing. An accurate scale with no more than 0.1% error of the test load. The charges or the steel balls. The number of steel balls used in the test depend on the gradation of the sample to be tested. The steel balls should have diameter between 46.038mm and 47.625, with mass between 400g and 440g each. A constant weight check should always be performed on the charges because this test is very aggressive and could lead in loss of weight of the charges.

It is recommended to go from higher to lower grade to gain accurate results. Wash and oven dry the sample at 110 ±5 °C (230 °F) to constant mass and then separate into individual sizes per their respective weights. Put the aggregates and the sample in the rotating drum. Close the Los Angeles Abrasion machine tightly and let it run for 500 revolutions at 30 to 33 rpm. After the drum stops take all the sample out and remove the steel balls from it. Now take the crushed aggregates and sieve it on 1.7 mm (No.12) sieve. Weigh the sample retained on the sieve and calculate the percentage loss. Micro Deval Micro-Deval is a test that involves measure of resistance of aggregates towards abrasion and test durability of the sample towards grinding of steel balls (ASTM D7428). The medium that is used here is water of room temperature. The sample and charges (steel balls) are kept in the Micro-Deval tank and then the apparatus is filled with water. The apparatus is rotated so that the aggregates undergo grinding and abrasion. The use of this test is mainly towards the aggregates that degrade more in presence of water than air. This test also gives a measure of how soft or shaley the sample is. The materials that give a high percentage loss degrade more during mixing or handling in industries. (ASTM D7428) Apparatus Micro-Deval Abrasion Tank with volume of 5.03 L and external diameter of 202mm and the internal height shall be from 170 mm to 177 mm. The stainless-steel tank comes with a rubber sealing to make it water-tight. The inner and outer surface of the tank should be smooth and ridge free. (ASTM D6928) Micro-Deval Abrasion machine is a rolling machine with an adjustable speed which rolls the tank at 100 ±5 rpm. Steel charges of diameter 9.5 ±.5mm are requires. The total mass of steel balls needed is 5000 ±5g. Sieves with 5mm and 1.25mm sizes are also required. An accurate scale with no more than 0.1% error of the test load. Table 3: Mass of Aggregates for Micro-Deval Test. Passing Retained Mass 20 mm 16 mm 375 g 16 mm 14 mm 375 g 14 mm 10 mm 750 g Take washed and oven dried sample so it loses the dust on it. Prepare a representative sample of 1500 ±5g put it in the Micro-Deval tank. Add 5000 ±5g of steel charges in it and 2.0 ±.05L of tap water in the Micro-Deval tank. Let this sit for 1 hour. After the sample, has been soaked tighten it up and put it on the Micro-Deval rolling machine to roll for 2 hours ±1 minute. After the machine stops rolling pour the sample on a stack of 5 mm and 1.25 mm sieve. Wash the remains of the sample in the tank on the sieve. Oven dry the sample at 110 ±5 °C and weigh it later. Calculate the percentage loss using the calculation sheet. Soundness Soundness test is a very crucial test in paving industries especially when making massive highways, bridges and dams. This test measure the amount of degradation caused by weathering freeze-thaw cycles. The aggregates that pass this test are more durable to be used and dont cause premature distress in pavements (http://www.pavementinteractive.org/article/durability-and-soundness/). The aggregates are kept in a sodium sulphate or a magnesium sulphate bath. The solutions is at a saturated state and causes salt crystals to be formed on the aggregates. This test is usually carried out for seven days which involves simultaneous wet-dry cycles. When the sample is submerged in the salt solution bath, salt crystals are formed in minute pores of the aggregates and causes internal forces that eventually lead crack in the aggregates. This gives us a replicated demonstration of how the substance will behave in natural habitat. This test has very poor repeatability so it is never considered as pr imary test to measure the degradation of the aggregates. Apparatus Sieves of different sizes- 5à ¢Ã‚ Ã¢â‚¬Å¾16 in., 3à ¢Ã‚ Ã¢â‚¬Å¾8 in., No. 50, 1à ¢Ã‚ Ã¢â‚¬Å¾2 in., 5à ¢Ã‚ Ã¢â‚¬Å¾8 in., No. 30, 3à ¢Ã‚ Ã¢â‚¬Å¾4 in., 1 in., No. 16, No. 8, No. 4. Metal baskets made of wire mesh or stainless steel that allows the aggregates to freely contact the solution and permit free drainage of the loss of sample. Temperature regulator to ensure that the temperature of the sulphate bath is constant at specified one. Balances with the accuracy of 0.1% are must for this test. Hydrometers are also needed for this test to measure the specific gravity within  ±0.001. Procedure Prepare the sodium sulphate solution that has specific gravity between 1.154 and 1.171. COARSE AGFREGATES Mass of the Sample Sieve Size Mass 2 in. (50 mm) 3000g 1.5 in.

Mix the 2 inch and 1.5 inch retained material and place the 5000g sample in a container. Mix the 1 inch and 0.75 inch retained and place the 1500g sample in a separate container and mark the container by making a groove on it with a particular symbol so it does not get mixed up with the other containers. This way it is also more efficient to identify them when changing the cycles. Mix the 0.5 inch and the 0.375 inch retained samples and put the 1000g sample together in a container. After the test samples are ready place them in the solution prepared for 16 to 18 hours and then let them drain for 15 minutes. Let the sample oven dry at 110 ±5 °C for 4 hours and then let them cool down until they reach 20  °C to 25 °C. Again, immerse it in the solution and repeat this cycle 5 times. After the 5 cycles are done the aggregates are to be washed thoroughly so that all the salt on the surface is removed and then oven dried at 110 ±5  °C. Table 4: Sieve Sizes to be used to Measure Loss Aggregate Size Sieve Used >1.5 inch 1.25 inch 1.5 to 0.75 inch 5/8 inch 0.75 inch to 0.375 inch 5/16 inch 0.375 inch to No.4 No.5 Use the above given table to respective sieve the aggregates used in the test. Utmost care must be taken to sieve samples from each container separately. Take the sample that is retained on the sieve and weigh it to note it. The difference in the mass of the aggregates before and after the experiment gives us the amount lost due to the disintegration of the sample. To compare the results of the following three, test a study was examined in which 20 Lab results were considered. These tests were performed by Montana Department of Transportation either in the Montana State University soil laboratory or Montana Department of Transportation (MDT) Helena materials laboratory. The samples were obtained from various random pits and quarries across Montana by MDT personnel. (Western Transport Institute) To get a very good relation and a study between these test, 5 repeats were done on the Micro-Deval test and at least 3 repeats were done for L.A Abrasion test. This also provided a good study of the repeatability of the tests. There was no repeat test done on the soundness test since it has a very poor repeatability. Repeatability To analyse the repeatability of the tests, repeated Micro-Deval and Los Angeles Abrasion test were done on the same sample. The Coefficient of Variation was calculated to examine the variation in the test results for the same sample. There was no COV calculated for the Sodium Sulphate Soundness test because only one test result was provided by MDT. The Coefficient of variation is standardized measurement calculate by diving the standard deviation of a set of results by the average mean and then multiplying it by hundred to get a percentage value. By analyzing and comparing this value we can predict the repeatability of the test. If the COV is a lower number, then the test is less variable and hence it has a good repeatability. The COV calculated for L.A abrasion test came out to be 6.5% with standard deviation of 1.5 loss percentage. Similarly, the COV for Micro-Deval test came out to be 6.5% for a standard deviation of 0.7 percentage loss. Since both the Coefficient of variations are less than 10%, both the tests are considered to have good repeatability. Another evidence to support the repeatability of the test is that there is no significant difference in the COV of Micro-Deval and L.A abrasion which are 6.6% and 6.5% respectively. As per the comparative bar graph plotted below, majority of the coefficient of the variation fall between 5% to 15%. The COV of Lab number 861553 rocketed to 26.9% because the result was very small accounting to be 2.1% average loss. So, a small change in small result make a large COV. Figure 1: Graphical Representation of Coefficient of Variation for L.A Abrasion and Micro-Deval Tests. COMPARTITIVE RESULTS As per the specifications provided by American Standard for Testing Materials the aggregates are classified as durable if the loss percentage is less than the cut-off percentage and they are non-durable if the loss percentage of the aggregates is more than the cut-off percentage. The cut-off percentage that we have used for L.A Abrasion, Micro-Deval and Sodium Sulphate Soundness Tests are as follows: LA abrasion: Passed if loss à ¢Ã¢â‚¬ °Ã‚ ¤ 40% Micro Deval: Passed if loss à ¢Ã¢â‚¬ °Ã‚ ¤ 18% Sodium Sulphate Soundness: Passed if à ¢Ã¢â‚¬ °Ã‚ ¤12% To create a direct comparison in between these tests normalized value for each test is calculated. Normalized value is used for a direct comparison between Micro-Deval, L.A Abrasion and Sodium Sulphate Soundness test. Normalized value is average loss percentage divided by the cut-off for that test. (MDT paper) The ideal Normalized value is 1.0. If the calculated normalized value is greater than 1.0 it means that the test did not pass and the aggregate tested are not durable and if the value is less than 1.0 it means that the aggregates are durable and the test passed. To draw a direct comparison in between two, test a two-dimensional scattered graph is plotted with four quadrants. The top right (North-East) quadrant depicts the are where both the test failed and the aggregates are not durable. The top left (North-West) quadrant depicts the area where the test plotted on the X-axis passed but the one on Y-axis failed. The bottom right (South-East) quadrant indicates the area where the test plotted on the Y-axis passed but the test that was plotted on X-axis failed. The bottom left (South-West) quadrant depicts the region where both the tests passed and the aggregates are durable. The data points plotted in the top-right (NE) and bottom-left (SW) quadrants indicate that the tests are consistent as the aggregates were either durable for pass/pass or not durable for fail/fail. On the other hand, the data points plotted in the top-left (NW) and bottom-right (SE) quadrant indicate discontinuity and lack of coherence since one of the test would indicate that the aggregates passed the cut-off and are durable while the other would indicate that they didnt pass are not durable for use. L.A abrasion vs Micro-Deval. Figure 2. Graphical Representation of Comparison between Normalized Loss of L.A Abrasion and Micro-Deval Tests. The above shown graphical representation is the plot of comparison between the Micro-Deval and the L.A Abrasion test on 20 different samples that were tested by Montana Department of Transportation. The blue dotted line that runs at 45 ° along the centre of the graph indicates symmetry and a perfect correlation. The data points close to the line indicate a good co-relation between the test. There was only one result that had failed both the test and was considered to be non-durable which accounted 5% of the materials tested. There were five results (25% of the samples tested) that fall in the awkward category and had lack of coherence since, according to L.A abrasion test it passed as was considered durable but according to the Micro-Deval test it was considered to be non-durable. The relations between these two test is quite strong as 70% of the samples tested i.e. 15 out of 20 passed the test and fall in the bottom-left quadrant which indicates that the samples were durable accor ding to both the test.

The co-op report guidelines suggest separating the Results and Discussion sections. I think that it is usually easier to present a discussion immediately after the results. But, you may choose to use the structure that makes the most sense for your report. Gregates typically encountered on Montana highway projects, and to determine if the MicroDeval test provides better, timelier, and more repeatable information about the quality of an aggregate than the Sodium Sulfate test. The laboratory testing program was structured to examine how well three aggregate durability test methods correlate for a sampling of Montana soils. Aggregate durability tests were conducted on 32 different soils using the Micro-Deval, L.A. Abrasion, and Sodium Sulfate tests. Multiple Micro-Deval and L.A. Abrasion tests were conducted on some of the soil samples to investigate the same-lab repeatability of the test methods. The methods differ in their treatment of the aggregate during testing; and consequently, each method produces a unique value of percent loss, which is used to distinguish between durable aggregate and non-durable aggregate. For the purposes of this study, the following percent loss pass-fail standards were used for each test: à ¢Ã¢â€š ¬Ã‚ ¢ Mic ro-Deval: passing (durable), if % loss à ¢Ã¢â‚¬ °Ã‚ ¤ 18%; à ¢Ã¢â€š ¬Ã‚ ¢ L.A. Abrasion: passing (durable), if % loss à ¢Ã¢â‚¬ °Ã‚ ¤ 40%; and à ¢Ã¢â€š ¬Ã‚ ¢ Sodium Sulfate: passing (durable), if % loss à ¢Ã¢â‚¬ °Ã‚ ¤ 12%. Because of the differences in percent loss criteria for each method, results from the suite of laboratory tests were normalized to facilitate direct comparisons between the three methods. Normalized results were obtained by taking the average percent loss for a particular soil and dividing it by the cutoff for that test. Table 16 summarizes the comparisons between each test using data collected during this study. Based on the metrics identified in the table, the MicroDeval and Sodium Sulfate tests had the best correlation, while the Micro-Deval/L.A. Abrasion and the L.A. Abrasion/Sodium Sulfate correlations were significant, but not as strong. Table 16. Summary Comparison of Test Methods Test Methods R2 Pass/Fail Agreement (%) Inconsistent Durability Determina tion* (%) M-D versus NaSO4 0.72 92.9 7.1 M-D versus L.A. 0.46 85.2 14.8 L.A. versus NaSO4 0.28 84.0 16.0 Perfect Correlation 1.0 100.0 0.0 *Note: Column 4 refers to the percentage of samples that passed one of the tests but failed the other test. This inconsistency is identified as a data point that plots in one of the cross-hatched zones identified in Figures 3, 4, and 5. Conclusions and Recommendations Western Transportation Institute 35 The percentages of inconsistent durability determinations (pass or fail inconsistencies) listed in column 4 of Table 16 are indicative of a discontinuity between tests and are probably the most important metric for the comparison study. In this case, one test characterized the material as durable aggregate, while the other test characterized the same material as non-durable aggregate. Qualitatively, the authors believe that an excellent correlation between two test methods is obtained when the percentage of inconsistent results is less than about 5%, values between 5 to 10% signify a good correlation, values between 10 to 20% signify a fair to poor correlation, and values above 20% signify a poor or unreliable correlation between tests. Multiple tests conducted on samples obtained from the same sources indicate similar values of same-lab repeatability for both the Micro-Deval and L.A. Abrasion tests. The coefficients of variation for the multiple tests were less than 10% for both methods. Considering the natural variability that occurs within an aggregate source, the measured variations were low, indicating good repeatability of the test methods. This conclusion has also been supported by others (Jayawickrama et al., 2006; Tarefder et al., 2003; and Hunt, 2001). Repeatability of the Sodium Sulfate test was not examined in this study. The relationship between Micro-Deval test results and field performance was not examined in this study; however, evaluations by Fowler et al. (2006), Rangaraju et al. (2005), Tarefder et al. (20 03) and Wu et al. (1998) indicate that Micro-Deval test results relate well with field performance. An excellent correlation between rutting performance and Micro-Deval test results were observed by White et al. (2006). They sug There are many reference styles available to choose from.

Lord Of The Flies Passage Anal :: essays research papers

Golding uses chapter eight to show the changes within Ralph and Piggy. The experience on the island has caused them to mature early, and Golding develops this maturity in order to provide the reader with a believable story and memorable characters. He develops the characters through vivid details, distinct diction, simple syntax, and congested figurative language. Golding uses detail to show Ralph’s change from a civil leader to a mindless savage. When Ralph sits and pokes holes in the sand, he is â€Å"surprised† to see blood. He examines his nail and is interested, not concerned, about the blood. He originally was disgusted at the site of blood. This act shows his savage-like fascination with blood. Piggy’s development is also dependent on Golding’s use of detail. Within this passage, Piggy wipes off his glasses twice. There is a sense of paranoia and urgency in this act. Piggy wishes to disconnect from reality and does not want to admit to himself or Ralph their desperate situation. Piggy was originally the voice of reason in the novel. This simple act, however, shows he is changing into an unadmitting fool because he chooses not to see reality due to fear.   Ã‚  Ã‚  Ã‚  Ã‚  The use of diction is also vital to the development of the characters in Lord of the Flies. The passage opens with Ralph â€Å"smudging the sweat from his face with a dirty forearm.† This conveys to the reader an exhausted boy who is at wit’s end. The words â€Å"smudging,† â€Å"sweat,† and â€Å"dirty,† connote savagery, and they show Ralph’s animalistic characteristics coming out. He has changed from a polished, civilized boy to a dirty savage since the arrival on the island. Ralph also runs around the fire â€Å"holding up his hair† when he realizes that most of the boys have joined Jack. This reference to hair shows the savagery in Ralph, as opposed to his clean-cut original appearance.   Ã‚  Ã‚  Ã‚  Ã‚  Syntax is another technique used by Golding to further develop the characters. The frequent use of dashes, fragments, and simple sentences remind the reader that although they are encountering a very complex situation, the characters are still simple-minded children. It also shows the characters’ fragmented thoughts and fears. Originally, Ralph was a well-spoken leader, but in this passage, Golding shows he is a scared creature through syntax.   Ã‚  Ã‚  Ã‚  Ã‚  Figurative language is employed by Golding throughout the novel to develop plot and characters. In this passage, the most vivid figurative language is in the final paragraph.

Leadership Styles in Professional Nursing Essay

According to Hood (as cited in Agnes, 2005) â€Å"Leadership is defined as a process of influencing others or guiding or directing others to attain mutually agreed upon goals† (p. 457). This paper will describe four different leadership styles, and the effectiveness of each style as dependent upon the situation. Review of the Professional Nursing Literature All nurses are leaders but may not recognize the different types of leadership or traits of an effective leader (Sims, 2009). There are four leadership styles to consider, the first one is autocratic or authoritarian. The autocratic leader is someone who usually needs to dominate others. The autocratic approach is often one-sided and the leader is likely attempting to achieve a single goal or objective (Sims, 2009). Autocratic leadership is a behavior in which a leader makes choices with no involvement from any peers, regardless if those ideas are better suited for the organization. This type of leader requires constant pressure and direction to get the task done. This type of leader provides clear expectations for what, when, and how a process should be done without consulting employees. Organizations that have this type of leader tend to see a high turn-over of employees and absenteeism for the simple fact that employees don’t feel valued. This approach would not be the way to get the best performance from the team. The implementation of this style of leadership could be used in a situation where an immediate decision needs to be made such as a crisis in an emergency room. The second leadership style is democratic or participative. This style is one that encourages employees to be a part of the decision making process. This type of leader keeps employees informed about everything that affects the work being done, and shares in the problem solving situation. A drawback of this type of leader is that the leader could be viewed as not being able to make a decision; therefore, the employees may not respect this style and view this leader as not being a true leader. The democratic leader uses the team approach and is the coach in the process, but has the final say when the group comes to a consensus. Implementation of a democratic leadership style can best be executed in a situation where a process or practice change is needed, such as documentation on electronic medical records. With this leadership style the leader can get staff ideas and suggestions for a smooth transition to the change. This not only increases job satisfaction by involving team members, but it also helps to develop people’s skills. This method inspires a group effort, but it can take lots of time for the leader to develop and come to an end to the topic at hand (Sims, 2009). The leader may spend a lot of time in discussions, sending emails, or scheduling meetings. This leader may be happy to do this to see that staff are working together to achieve a better outcome, but it can also be a time-consuming process. A good democratic leader encourages staff participation, is supportive, but never loses sight that the leader is the one responsible for the final decision. This leader must accept that the outcome may turn out differently than originally planned. Transactional leadership is the third style, and is one where the leader focuses on the day to day tasks of the team, and makes sure that the work is completed. Transactional leadership is really a type of management, not a true leader style, because the focus is on short-term tasks. Transactional leaders set a goal, provide directions, and then reward the employee if performance is met at an acceptable level (McGuire & Kennerly, 2006). Transactional leadership style can best be used when a state survey is taking place and if successful, then reward will be given to the employees. These leaders use this style to get the desired outcomes. Transactional leaders give tasks to be done by the employee, and if it’s done wrong then the employee is accountable. If the task is completed to this leader’s standard, then the employee is rewarded. This type of leader doesn’t focus on the staff’s needs, or personal development, instead the staff must adhere to what the leader wants. Transactional leaders often work under the assumption that if everything is working fine, then there is no need to fix anything. Under this type of leader, there is no interest in change, and the employee will not feel any job satisfaction. The fourth leadership style is the transformational leader. This style of leadership is one that’s very appropriate in many corporate situations because of the wide range of abilities and approaches that are drawn upon. This style focuses on the leader and the employee working together for a common goal. This type of leader has a vision for the organization, and inspires employees to solve problems creatively in a way that provides support and encouragement without diminishing the nursing role (Kleinman, 2004). Transformational leaders have several traits that inspire the employee to utilize the strengths to improve the team, have better staff satisfaction, and reduce stress (Weberg, 2010). Transformational leaders are coaches, or mentors; they show respect, have empathy, and utilize individual leader skills to promote change. These leaders are very energetic and passionate about the job, and concerned about all staff in succeeding. These leaders set good examples, clear goals, and recognizes good work from the team. Transformational leaders should remain a part of the team and share in the work load to better understand the team’s viewpoint. With this leader style, there is a higher level of committed employees, reduced stress, and increased morale (Dunham & Klafehn, 1990). This in turn creates an employee who will provide a positive outlook when change is taking place and increases employee job satisfaction. Application of Clinical Example A clinical example of when transformational leader style would work best is when an organization is going through a change process, such as the way report is given. Transformational leaders motivate staff to work towards a greater good and create a positive change (Dunham & Klafehn, 1990). Many nurses don’t like change in the way care is provided, but when it’s important for patient safety change is inevitable.

Report on Feasibility Study to Start a Restaurant Essay

Hotel industry is one of the essential industries. This industry serves the different customer in different aspects like taste, preference, price, quality etc. In Chennai, many varieties and range of hotels are available. As Chennai is the manufacturing hub of India, different class of people make business meetings and dealings in different hotels which provides these facilities. Wide range of people travel to Chennai to earn their living and the thriving population has mostly increased in the past few years. Apart from hotels, restaurants are the highly targeted places in Chennai. In this fast moving world, people do not have time to cook their own food and take it to their work place and even get ready with their breakfast. So, restaurants with different traditions of the south as well as north are started in and around Chennai. Considering this aspect, an idea to do research on the feasibility of starting a restaurant in Tambaram was taken up. Near Tambaram many manufacturing industries have rose up and the places in and around Tambaram have become residential areas but the number of restaurants is limited. So there is a niche market to be captured by opening a restaurant in that area. Thus the aim of this study is to know the customer preferences about the varieties of food and other aspects which will bring up the restaurant as a successful one. Chapter – The focus group is a qualitative research method designed to ascertain the opinions, attitudes, and behavior of target audiences. Typically, 8-10 persons meet to discuss topics selected and presented by a moderator, who afterwards prepares an analysis. For the feasibility study of starting a restaurant in Chennai, two focus group interviews were conducted with 10 participants who were native of Chennai and participants who were related to the hotel industry. In a controlled environment for duration of 90 minutes, the focus group interview was conducted in the presence of a moderator. Different ideas related to the customer involvement and expectations in the different food recipes and the external and internal environment of the hotel were discussed.

ORDER MY AMERICAN DREAM ESSAY What is the American dream essay The American dream has always been an important part of the culture and society in America. It still remains relevant in modern times. What is the American dream? It’s worth mentioning that people can’t measure it bases on what they have because they need to apply its principles to social matters and trends. The first part is the dream of abundance. It’s all about the ability to be filled with material goods. Many other countries envy a nation or consumers and producers because only a few of them can match the sheer range of goods that America makes. Think about the dream of democracy and equal rights. This concept is about people’s ability to buy goods, regardless of who they are and where they’re from, and it links back to their constitutional rights. The dream of freedom of choice is another important part. It ties back to the state constitution, which allows people to choose their own lifestyles, use different goods, and have the freedom to be who they want to be. Don’t forget about the dream of novelty. It’s all about the concept of a broadening of consumer choice and it has a huge impact on the American society today. Current skills on demand keep changing over time. It’s not necessary for people to specialize in specific areas to get along in their lives because they can be sure that there’s always a demand to niche skills to provide them with more freedom of choice. The constitution is significant for the American dream because it wouldn’t be able to persevere without this legal document. Nowadays, the American dream stays relevant. How people make it come true change, but its basic principles remain the same, and the main difference is that young people choose innovation methods to go about their pursuit. The American dream is a symbol of prosperity. Does the American dream still exist today essay Some people argue whether the American dream remains obtainable and alive. They all have unique values and lives. This means that people have different definitions of the American dream. One of the main reasons why it’s alive is that there are endless opportunities that people get on a daily basis. Many public schools provide their students with the tools and methods they require to succeed, so it’s only up to them if to use them to achieve life goals or not. What’s next? Another fact proving that the American dream exists is that people have multiple job opportunities at their disposal. Not all of them end up becoming famous lawyers or doctors, but they all can be successful and earn their living. The world is full of available opportunities. There are different jobs to choose from, such as construction workers, apprentices, electricians, technicians, lab employees, engineers, and so on. It’s not even necessary to attend any college. There are many successful and prosperous people who failed to obtain their college degree, but it didn’t stop them from making the American dream come true. Why do people feel that it’s not alive today? Most of them end up thinking this way because of the economy. America has weaker job markets and slower economic growth, and that’s why most interest rate profits don’t go to the public. The national debt is quite high, which is another contributing factor, but it results in higher taxes that help earn more revenue. The major negative effect of the national debt is increasing inflation. It can lead to lower standard of living. Despite the above-mentioned negative trends, there are positive concepts and factors proving that the American dream still exists in the modern world. Many people keep pursuing it for different reasons. Some of them want to be happy, while others prefer to get rich or achieve other life goals.

Kuder - Assignment Example These reflect my personality as well as my upbringing. I have always been an individual who is ready to help and would not think it impossible to advance the interest and welfare of others above my own or in the interest of the greater good. In looking at specific variables in the result regarding the potential industries that I would thrive in, I realized that these are aligned with what I have been interested early on. For instance, I got high marks on health science. This was not really surprising because I have always been interested in biology in high school. I could still remember promising to be a doctor after we viewed a video lesson about avian flu and the impact of an epidemic on people. The focus of my extracurricular activities also reflected my interest in areas such as communication, technology and relationship with people. There are certain areas in the result that perplexed me a little. I scored high in education and training yet I did poorly in hospitality and tourism industries. The reason for this is that I have been considering a career in the latter cluster since I do like to cook and I am curious about the hospitality industry whereas the academe has not entered my mind as yet. But when I saw my work values I sort of understood this part. I am quite independent with a deep hunger for accomplishment: that is, I had to know and feel that I am doing something meaningful and important not just for others but also for the society. This thought also helped me understand why – according to the assessment - I might not excel in managerial and administrative positions. My ethnic background sets great importance to management position and those around me tend to believe that it is one of the ultimate objectives of any career, to be the boss. I found that I will be more successful elsewhere. With all the information I have from the Kudder and Work Values assessments, I feel I am more in the position to choose the

Debt in the firms balance sheets Essay Example | Topics and Well Written Essays - 1750 words

Debt in the firms balance sheets - Essay Example The paper presents ordinary shares that can be simply defined as shares which are not preferred shares and which do not offer fixed dividend amounts. As Nevin states, an ordinary share directly indicates equity ownership in a company and it entitles the owner to voting rights in various crucial affairs of the company in proportion to their percentage of shareholding. Ordinary shareholders are entitled to receive dividends on their investment only if anything left after all liabilities are paid. In contrast, debt is an obligation owed by one party (debtor) to another party (creditor). In case of debts, lenders have no rights on the firm’s operations and are unable to take part in determining major strategic issues. Organisations and businesses across the world use debt to finance their day to day operations and other particular projects. The levels of debt are fundamental macroeconomic data and it they largely vary from company to company. Generally, levels and flows of public debt are given central importance while levels and flows of private debt are not considered as a major cause of concern. Stocks and flows are two important tools of debt measuring. Stocks are levels of debt and they have units of currency whereas flows change in debt levels and have units of currency/time. All credit is debt and it is created by lenders who agree to lend money for the exchange of adequate future returns. Lundgren reflects that the amount of money lent is considered to be the asset of the creditor while it becomes the liability of the debtor. Debt is often issued along with a specific repayment plan; and the debt maturity time or period of repayment may range from a few days to 50 years or longer. According to the maturity period, debt is classified into three categories such as short term, medium term, and long term debt. In order to accurately calculate total debt of a business, it is necessary to take off-balance sheet debt into account as all debt items may not s how up on the balance sheet. As Shearn (2011, p. 116) states, these debt items may include lease obligations, warranties, purchase contracts, unfunded pension liabilities and any other contractual obligation. However, this type of debt is generally disclosed in the footnotes attached to the financial statements. White, Sondhi & Fried (2006, p. 323) indicates that the liability amount shown on the balance sheet may not always represent total cash flow required to meet the debt. Business houses only record the present value of the future cash flow. To illustrate, if a firm borrows $1,000 at an interest rate of 12%, total amount payable at the end of that period becomes $1,120. However, the balance sheet will only represent the present value of the future payment or $1,000. Factors affecting levels of debt As Crane, Knoop, and Pettigrew (1977) point out, different firms have varying strategies in maintaining their debt levels and this strategic differences cause debt level variances in firms’ balance sheets. A firm considers an array of factors before framing its debt level strategies. In the words of Long and Ravenscraft (1993), no firm would allow its debt level to grow beyond its repayment capacity as this condition may adversely affect the feasibility and market repute of the business. More precisely, a firm’s debt level heavily depends on its borrowing policies. â€Å"Tthe capacity to borrow depends on several factors such as profitability, stability, relative size, asset competition, and the industry position of a business† (Shearn, 2011, p.115). Hart (1995, p. 142) argues that profitability plays a pivotal role in determining the debt level of a business house. General trends indicate that level of debt will be in an

Financial Accounting assignment Speech or Presentation

Financial Accounting assignment - Speech or Presentation Example payment of dividend to the preference shareholders is under the discretion of the board of directors of a company, whereas the interest payment for debentures is not under their control. Interests on debentures are tax deductible whereas dividend payments are not. In the case of a company going insolvent, debentures get preference over the preference shares (Harvard, 2009). A stock exchange placing will enable the company to raise the additional funds very rapidly. However the company has to also satisfy the demands of the common shareholders and a number of changes have to be brought in terms of the management and policies. There is also a possibility of another company placing a bid to acquire the company through the stock exchange. A stock exchange placing can also act an effective marketing for the company, as the more people will become aware of the business (Hobson, 2007). A rights issue is offered to all exiting shareholders, as opposed to stock exchange placing where the stocks are open to common public. The shares are issued based on a ratio, for instance, every share qualifies to buy another four shares, for a specified period of time. The shareholders can either accept or reject the offering. There is a possibility that the required capital may not be raised, as the shareholders may not accept the offering. However, the company does not run the risk of adding more shareholders and also taking the risk of mergers and acquisitions (Hobson, 2007 and Keef, 1992). The additional capital required can also be raised by not paying the dividends to the shareholders for the financial year. The main advantage of this method is that there are no additional costs involved in raising capital. However, it is to be noted that the shareholders may not be happy with this decision and it might have a negative effect on the potential investors (Frankfurter, Wood and Wansley, 2003). The net present value is computed by discounting the future savings to present values at

Complaint letter (Analysis of a unsatisfactory experience with a Essay

Complaint letter (Analysis of a unsatisfactory experience with a company) - Essay Example As a result of this situation created by your establishment, I was forced to seek for a cheaper accommodation in the nearby town, a situation that led in the delay of the opening of the International Orphan Conference I was supposed to attend. In fact, to state that I was subjected to a psychological and emotional torture accompanied with an outstanding public embarrassment would be an understatement. As it has been the custom, over the years I have had countless satisfying stays in your hotel located in San Francisco, a convenient place for the nature of programs that we hold within and outside the states. Prior booking has also been the most convenient business method between the hotel management and me until the recent event. As you can imagine, the experience went way below my expectations with much consideration of the huge amount of money that I spent in your facilities during the numerous visits. In addition, I have played a huge role in encouraging my friends to use your facilities for conveniences as it was the case before this disappointing incidence. In the light of this, I am not certain if I will ever feel comfortable seeking services from your establishment. As such, I humbly request for a thorough investigation to be conducted involving the accommodation arrangement to establish why I encountered such an embarrassing situation even after I had booked a room and paid for one of the most important events I was to attend. Furthermore, I would recommend that legal and ethical actions should be taken against the culprits to swiftly curb and/or reverse this worrying trend and resolve the grossly appalling issue. To be honest, your response to my concerns will highly determine on the further action I will take.

Corporate law Master Case Study Example | Topics and Well Written Essays - 2000 words

Corporate law Master - Case Study Example Thus, from all appearances the corporation is indeed a close one. If it was not stated that the spouses Paul and Mary had registered the company in 1980 with the name Scott Enterprises PTY. Ltd., the first thing that would come to the mind is that the spouses must have formed a partnership instead because the business originally involved only the two of them i.e. the spouses. Most partnerships involve only two business partners (Clifford 2006, p.7). But such is not the case here, although if I were the spouses' adviser at the time they contemplated to form a business entity, I would have suggested a partnership instead because a partnership is simpler and entails no further elaborate requirements to satisfy the requirements of the Corporation Act. Besides, it entails less expenses than incorporating and gives them more leeway and freedom of action than incorporation, which puts one to the reins of government control. If the spouses chose partnership instead, either Paul or Mary can bind the partnership by any legitimate contract in the ordinary course of business of their manufacturing concern. But probably, the spouses had in mind the future of the company. ... ey might be forced to retire from the business due to old age, debility, sickness, incapacity or even worse death to any or both of them (Humphreys 1998, p.6-1). Corporation provides more stability because it affords the right of succession, in which case if any of the above occurs, they can safely ensconce the corporation in the hands of the three children - Suzy, Peter and Sam (Dine 2000, p.101). A corporation ensures continuity and permits transfer of shares of their stocks to the three children if any of the above happens. Perhaps, the spouses want to see the company they laboured hard to put up go a long way and they desire to experience the fruits of their hard work when this company is already in the hands of their children. A corporation just cannot be dissolved voluntarily because it requires a vote of two thirds of the stock and its dissolution can only take place by some judicial or administrative act of the government ( Davis 2000, p.6). 3 The form of corporation can only be a close corporation because all of the corporation's issued stocks are held of record by only 5 persons, with the three children holding each 30% of the shares and the 10% share being retained by the spouses. Although the case is silent about any action to make a public offering of the shares of the corporation or to enlist the corporate shares in any stock exchange, yet the tenor of the case strongly suggest that the spouses never did any of these acts nor have any intention to make one in the future (Moye 2004, p.209). The resolve to keep the business within exclusive family control is so strong we can just surmise that the

Geometrical Optics And Its Applications

Geometrical Optics And Its Applications Optics is the cornerstone of photonics systems and applications. Geometrical optics, or ray optics, is to study the geometry of paths of lights and their imagery through optical systems. Light will be treated as a form of energy which travels in straight lines called rays. When light comes to be regarded as waves, it will be seen that shadows cast by objects are not as sharp as rectili (Ariel Lipson,Stephen G. Lipson,Henry Lipson) (Ariel Lipson,Stephen G. Lipson,Henry Lipson, 2010)near propagation suggests due to diffraction and interference effects of wave. Thus, there is a simple assumption for geometrical optics, which is rays of light propagate along straight lines until they get reflected, refracted, or absorbed at a surface. 2 Fermats Principle 2.1 Background Fermats Principle, also known as the principle of the shortest optical path, was introduced by Pierre de Fermat in the early seventeenth century. This principle is used to state and explain the motion of light ray through different media, which helps to demonstrate laws of reflection and refraction later on. 2.2 Theory The path of a light ray connecting two points is the one for which the time of transit, but not the length, is a minimum. The time, T , for a light ray through space to travel from a point A to another point B can be calculated as: It is known that is velocity, which can also be regarded as for light, where c is the speed of light and n is the refractive index of the medium. Thus, we have Then the path taken by light should be the path that minimizes this integral, which would be: Therefore, it is the fact that light will travel along paths of stationary optical path length, where the optical path length is a local maximum or minimum with respect to any small variation in the path. And many paths will take exactly the same time to travel from point A to point B. (Ariel Lipson,Stephen G. Lipson,Henry Lipson, 2010) 3. Reflection 3.1 Derivation for Law of Reflection In general, law of reflection states that when a light ray incident upon a reflective surface, it will be reflected with an reflective angle that exactly equal to the incident angle with respect to the normal of the surface. Law of reflection can be dervied from Fermats Principle. Assume that the medium of the light travel is homogeneous, we haveC:UsersGaryDesktopà ¦Ã…“ ªÃƒ ¥Ã¢â‚¬ËœÃ‚ ½Ãƒ ¥Ã‚ Ã‚ .png Total path length S from A to B is Based on Fermats Principle we know that light would travel the path with minimum time. As in homogeneous medium, light travels with a constant speed and therefore the minimum time path is equilvant to the minimum distance path, which can be obtained by taking the first derivative of S with respect to x. which is sinà £Ã¢â‚¬Å¾Ã‚ ¥AOC = sin à £Ã¢â‚¬Å¾Ã‚ ¥BOC Thus shows that à £Ã¢â‚¬Å¾Ã‚ ¥AOC = à £Ã¢â‚¬Å¾Ã‚ ¥BOC, the angle of incidence equals the angle of reflection NB: It has to be reminded that the incident ray, the refracted ray and the normal are co-planar. (Philip D. Straffin, C. T. Benson, 1993) 3.2 Specular and Diffuse Reflection In details, there are two types of reflection Specular reflection and diffuse reflection. http://titan.bloomfield.edu/facstaff/dnicolai/images/ImagesPhy106/lesson2.gif Specular or regular reflection is said to occur when parallel rays reflect from a high smooth and flat surface. For instance, a flashlight beam is said to have specular reflection as the reflective surface is mirror which is highly smooth and it, hence, makes the reflected beams travel towards the same direction in parallel as in (a). Most object, however, reflect light diffusely and the rays in an incident parallel beam are reflected in many direction as in (b) because of diffuse reflection. Diffuse reflection is due to the surface of the object not being perfectly smooth like a mirror. In fact, under microscopic scale, the surface of most of objects, if not all, is quite rough. Although at each point on the surface the law of reflection is observed, the angle of incidence and the angle of reflection varies from point to point. Each of the initially parallel rays, therefore, is reflected in a different direction. 3.3 Mirror Concepts and its Applications 3.3.1 Image Formation with Mirrors Mirrors, undoubtedly, are ubiquitous in daily, especially used in mirror and optical instruments for gathering light and forming images. Law of reflection can be applied to use in locating the reflected image graphically as long as the size, location and orientation of the object is known. 3.3.1.1 Images in Plane Mirrors Images with mirrors are formed when many non-parallel light beams are reflected from the mirror surface and converge to form a corresponding image point. Image formed by plane mirror is erect, virtual, same size as the object and laterally inverted.C:UsersGaryDesktopreflection in mirror.png For a point object, in Fig 3.3.1.1a, rays from the object at O are reflected in all directions based on the laws of reflection so that they appear to come from a point I behind the mirror and this is where the observer imagines the image to be. For an extended object, in Fig 3.3.1.1b, the image of a point A on the object is at A, and two points are being equidistant from the mirror. Similarly, the image of point B is at B. The image size, therefore, is identical to the object seize, giving a magnification of unity. However, the right-hand side of the object becomes the left-hand side of the image and vice versa. The image is said to be laterally inverted.C:UsersGaryDesktopmirror extended object.png To conclude, a planar mirror is strictly stigmatic in nature Any incident rays issued from point A gives reflected rays passing through point B symmetrically to A with regard to the plane of the mirror. B, hence, is the image of A. (Katz, 2002) 3.3.1.2 Images in Curved Mirrors There are mainly two types of spherical mirrors, concave and convex. Similar to planar mirror, image can be traced using the law of reflection. Unlike image formed by planar mirror, which is always erect, virtual, same size as the object and laterally inverted, the image formed by a spherical mirror and its nature depend on the distance of the object from the mirror. To construct the image, we assume that small objects on the principal axes of mirrors of small aperture are being considered so that all rays are paraxial. Point images will, thus, be formed of points on the object. For concave mirrors, also known as converging mirrors because of their action on a parallel beam of light, is a mirror with a curved reflecting surface that bulges inward. The formation of image using concave mirror can be in different locations of the object can be concluded by the following figure. Concave Mirror The nature of image using concave mirror and its applications are summarized as below: Position of the object Position of the image Nature and size of the image Use At infinity At the focus Real, inverted and diminished As collector of radiation in solar heating devices Beyond the centre of curvature Between the focus and the centre of curvature Real, inverted and diminished At the centre of curvature At centre of curvature Real, inverted and same size as object As a reflecting mirror behind a projector lamp Between the focus and centre of curvature Beyond the centre of curvature Real, inverted and magnified In flood lights At focus At infinity Real, inverted and magnified As a reflecting mirror in car, head lights, search lights etc. Between the pole of the mirror and the focus Appears behind the mirror Virtual, erect and magnified As a shaving mirror or makeup mirror and dentists mirror (Katz, 2002) For convex mirrors, also known as diverging mirrors reflect the incoming parallel light beams to form divergent beams which appear to come from a point behind the mirror.Convex Mirror Unlike that in concave mirrors, the nature of image formed by convex mirror is always virtual, diminished and erect. (Katz, 2002) 3.3.2 Derivation of the mirror formula Mirror formula is useful when we have to calculate the image location. Using triangles 2 and 3, we have,http://scienceworld.wolfram.com/physics/mimg232.gif While using trangles 2 and 4, we have, Where is the image distance, is the object distance, f is the focal length, is the image height and is the object height It should be noticed that the sign convention is to be used in mirror formula. A real object or image distance is positive while a virtual object or image distance is negative. Magnification of a mirror image, m, can also be calculated by 3.3.3 Mirror instruments 3.3.3.1 Catoptric Systems Catoptric Systems is the system that merely consists of mirrors for the formation of image. (Board, 2012) 3.3.3.1.1 Newtonian telescopehttp://bdaugherty.tripod.com/gcseAstronomy/images/newtonian.jpg Newtonian telescope is the first reflecting telescope invented by Isaac Newton in 1668. It consists of a concave primary mirror and a small flat diagonal secondary mirror. In a bid to have a stigmatic axial image, a concave mirror has to be applied to act as a primary mirror and it reflects light back up the scope axis to the secondary mirror which is titled at 45o to the axis. The secondary mirror, which is a small plane mirror, is placed in the path of beams reflected by the primary mirror in order to divert the rays to one side of the tube. The reason for choosing a small mirror to act as secondary mirror is to prevent the influx of light beams is blocked from reaching the primary mirror. Pros of the Newtonian telescope Cons of the Newtonian telescope Less expensive Reduction of light intensity due to the blockage of central flat plane Shorter focal ratio leads a wider field of view Easily suffer from coma (i.e. an off-axis aberration) Free of chromatic aberration Simpler fabrication (Kitchin, 2012) 3.3.3.1.2 Cassegrain Telescope http://www.vikdhillon.staff.shef.ac.uk/teaching/phy217/telescopes/cassegrain.gif Cassegrain Telescope is another type of reflecting telescope employing two principal mirrors, a concave parabolic primary mirror like the Newtonians, but its secondary one is a convex hyperboloidal mirror. It makes use of the special properties of parabolic and hyperbolic reflectors. A concave parabolic reflector will reflect all incoming light rays parallel to its axis of symmetry to a single point, the focus. A convex hyperbolic reflector has two foci and will reflect all light rays directed at one of its two foci towards its other focus. The mirrors in this type of telescope are designed and positioned so that they share one focus and so that the second focus of the hyperbolic mirror will be at the same point at which the image is to be observed, usually just outside the eyepiece. The parabolic mirror reflects parallel light rays entering the telescope to its focus, which is also the focus of the hyperbolic mirror. The hyperbolic mirror then reflects those light rays to its other focus, where the image is observed. (Waland, 1990) 3.3.3.1.3 Gregorian telescope http://s4.hubimg.com/u/7341531_f520.jpg Gregorian telescope employs concave parabolic mirror to act as both primary and secondary mirror in this reflecting telescope. The light that first enters the tube is reflected by the primary concave mirrors and directed towards the secondary mirror, which is also a concave mirror. It will reflect the rays out to the telescope through the hole in its center. Observer can therefore view the image formed on the eyepiece. (Trà ¼mper, 2010) 3.3.3.2 Catadioptric Systems Catadioptric system, on the other hand, is the system that consists of both mirrors and lenses for the formation of image. (Board, 2012) Catadioptric Systems will not be included in this paper. 3.4 Other Applications 3.4.1 Optical lever and light-beam galvanometers Galvanometer is an instrument that used to measure very small electric currents. Some sensitive galvanometers would use a beam of light in conjunction with a small mirror as a pointer. When there exists current flowing in the electric wire, a tiny mirror that is fixed to the part of the meter will rotate. And a light beam from a fixed lamp falls on the mirror and is reflected onto a translucent scale. For a given current, the longer the pointer (i.e. the reflected beam) the greater the deflection observed on the scale. This simply applies the reflective nature of light wave. (A.M.Badadhe, 2006)http://www.daviddarling.info/images/moving-coil_galvanometer.jpg 3.4.2 Red-eye effect The Red-eye effect is a common phenomenon in photography. It occurs when the photographic flash unit place closely to the camera lens. Normally, the rationale of photo-taking is that light from the flash unit enters the eye and is reflected back to the camera lens. Nevertheless, under dark environment, pupil diameter would increase due to contraction of radial muscle fibers and relaxation of circular muscle fibers of iris under autonomic nervous system and therefore more light beams can enter into the retina of the eye. And the reflected light from the retina is red because of largely blood vessels in Choroid. It, therefore, gives the Red-eye effect in photograph. 3.4.3 Headlight of Carhttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgiA7zTY83raRLp9X-G7ZfdMobFuZnkU8o_FC95OPoijGXaVEiWn6GdgSjwiwy6pNjuaIICY3EyA0k1-qrPbx4NkusaD49vmOeoJ6fHxWqi46713EY5XRO_b8_grWvIFWGUSqNiQbo4gjCE/s1600/infiniti+headlight.jpg It employs concave parabolic mirrors at the front of the car, which acts as reflectors in the head lights of cars, search lights etc. 3.4.4 Dentists Mirrorhttp://cdn7.fotosearch.com/bthumb/FSA/FSA132/x12292469.jpg Dentists Mirror applies reflection to reflect and focus light on the tooth so that dentists can be examined in detail. 3.4.5 Optical Comparatorhttp://www.worldoftest.com/img/products/qv300_1.jpg Optical Comparator is an instrument that projects a magnified image or profile of a part onto a screen for comparison to a standard overlay profile or scale based on the principles of optics. The comparator, basically, is a non-contact device, which frequently used to measure, test, inspect, gauge or examine parts for compliance with specifications. (A.M.Badadhe, 2006) 3.4.6 Security Convex Mirrorhttp://dgmglass.com/images/mirrors/security/mirror-s-3.jpg One of the distinguish feature of convex mirror is the widely view range. Therefore, convex mirror is applied to act as a security mirror in blind junctions of roads or at corners of walls of bug buildings. The person that is approaching from other side would be shown when the mirror is positioned properly. 3.4.7 Rear-view mirror in an automobilehttp://transport-futures.com/wp-content/uploads/2011/04/rear-view-mirror.jpg Knowing that the size of image of an object would be smaller when the object comes closer to the convex mirror, this unique feature can be applied to use on automobiles as rear view mirrors so that the diver can clearly view an approaching vehicle. 3.4.8 Submarines PeriscopeC:UsersGaryDesktopreflecting Periscope.png A periscope is a mirror instrument for observation from a concealed position. It works by employing two mirrors at 45o to each other, reflecting light rays from one place to another and finally out to the persons eye. 4 Refraction 4.1 Law of Refraction Qualitatively, when a light wave, which in fact composed of oscillating Electric fields and Magnetic field, crosses from a low optically density medium, say vacuum into a high optically density medium, say glass, E-Field and B-Fields are altered in terms of magnitude and direction of travel by the charges in the glass. Law of refraction, however, can be proved mathematically as follows: The first medium is supposed to be faster than the second medium and the speeds of propagation in 1st medium and 2nd medium are and respectively, where c is the speed of light in vacuum and n1, n2 à ¢Ã¢â‚¬ °Ã‚ ¥ 1. C:UsersLenovoDropboxU life2012-13, year2, 1st semesterCCST 9042 The world of wavesSnellslaw_diagram2.png Then, we have to evaluate the time taken by light ray from P to Q, which is Based on Fermats Principle, light travels the path with the least time. Thus, in an attempt to minimize the transit time, we set the derivative of time is zero and we have: By trigonometry, we have As and, we have This is Law of refraction, also known as Snell-Descartes law. NB: Similar to law of reflection, the incident ray, the refracted ray and the normal are co-planar. (Philip D. Straffin, C. T. Benson, 1993) 4.2 Total internal reflection According to Snells law, when a light travels from one a medium with a higher optical density, to a medium with a lower optical density, say from glass to air, it will be refracted away from the normal (i.e. Ray C in Fig 4.2a) and a weak internally reflected ray is, meanwhile, formed (i.e. Ray B in Fig 4.2a) C:UsersGaryDesktopà ¦Ã…“ ªÃƒ ¥Ã¢â‚¬ËœÃ‚ ½Ãƒ ¥Ã‚ Ã‚ 33.png Increasing the angle of incidence i increases the angle of refraction r, and at a certain angle of incidence c, called the critical angle, the reflected ray beam just emerges along the surface of the glass and the angle of refraction is 90o (i.e. Ray D in Fig 4.2b). In Fig 4.2 c, as the incident angle is increased continuously above critical angle (i.e. i > c), the refracted angle will be higher than 90o and sin r > 1, which is impossible and no refraction is possible. At this stage the internally reflected ray becomes bright and the refracted ray disappears. Hence, total internal reflection is now said to be occurring since all the incident light is reflected inside the optically denser medium. Mathematically, the critical angle can be found based on Snells law, which is Assume that n1 is refractive index of optically denser medium, n2 is refractive index of optically less dense medium, ÃŽÂ ¸1 is the critical angle of denser medium and ÃŽÂ ¸2 is the angle of refraction in less denser medium. All in all, for Total internal reflection to happen: Light must travel from denser medium to rarer medium. Angle of incidence should be greater than critical angle (i.e. i > c.) 4.3 Thin Lenses Thin lens is a lens that its axial thickness is small compared to the radii of curvature of its surfaces. (I.e. The thickness of the lens is negligible compared with the focal length of the lens) There are mainly two types of thin lenses, Converging thin lenses and Diverging thin lenses. Converging thin lenses, also known as convex lenses, direct parallel light rays bending toward one another after passing through them Diverging thin lenses, or so-called concave lenses, cause parallel light beams to spread as the leave the lens.http://t1.gstatic.com/images?q=tbn:ANd9GcT6lXrPj04wfnztVlEvIlewlbzvIzhu_60Cup8oDYd840MY3w0SiOxnzxaVrQ 4.3.1 Image Formed by Thin Lenses 4.3.1.1 Convex Lens Ray DiagramFormation of Image by a Convex Lens Object is located between focus and lens The image is: Virtual Erect Magnifiedobject at F1 2.

Also, Thus, Combine with (1), we have NB: The Cartesian Sign Convention for thin lens formulas are as follow: Light travels initially from left to right toward the lens. Object distance p is positive for real objects located to the left of the lens and negative for virtual objects located to the right of the lens. Image distance q is positive for real images formed to the right of the lens and negative for virtual images formed to the left of the lens. The focal length f is positive for a converging lens, negative for a diverging lens. The radius of curvature r is positive for a convex surface, negative for a concave surface. Transverse distances are positive above the optical axis, negative below (Katz, 2002) 4.3.3 Power of a Lens The optical power of the lens is used to describe the bending ability of lens in term of power. Basically the power of a lens of focal length f is, Power, in the case, can be expressed in m-1as the unit of power is diopter 1 D = 1m-1 Therefore, if there exists a convex of power 1D, its focal length equals to 1 meter. 4.4 Optical instruments 4.4.1 Prismshttp://upload.wikimedia.org/wikipedia/commons/thumb/f/f5/Light_dispersion_conceptual_waves.gif/330px-Light_dispersion_conceptual_waves.gif Optical prisms are components that commonly used in optical experimental arrangements and optical instruments, with the role of illustrating dispersion of light beams. Rather than showing the complicated mathematical proof such as derivation of minimum deviation, application of prism will be illustrated below. (Thorington, 2009) 4.4.1.1 Prism BinocularsC:UsersGaryDesktopprism.png Prism Binoculars consist of a pair of refracting astronomical telescopes with two totally reflecting prisms (angles 90o, 45o, and 45o) between each objective and eyepiece. Prism A causes lateral inversion and prism B inverts verticallt so that the final image is the same way round and the same way up as the object. (Thorington, 2009) 4.4.1.2 PeriscopeC:UsersGaryDesktoppp.png Periscope, apart from using two reflecting mirror, employs two prisms. Under the occurring of total internal reflection on the hypotenuse, the incident rays and reflected rays are symmetric with regard to a plane orthogonal to the hypotenuse. In the case of normal incidence on one side of the right angle, the incident and reflected beams are orthogonal. 4.4.2 Magnifying Glasshttp://blog.timesunion.com/opinion/files/2011/02/0217_WVinternet.jpg Magnifying glass, also called Simple microscope, consist of a converging lens forming a virtual, upright, magnified image of an object placed inside its principal focus. For an object of height h is viewed at the near point by the unaided eye, the visual angle is, where D is the least distance of distinct visionhttp://www.astarmathsandphysics.com/ib_physics_notes/optics/ib_physics_notes_the_angular_magnification_of_a_magnifying_glass_when_the_image_is_formed_at_the_near_point_html_m367c081d.gif Now the object is placed at distance u from the lens, the visual angle subtended by its image is given by http://www.astarmathsandphysics.com/ib_physics_notes/optics/ib_physics_notes_the_angular_magnification_of_a_magnifying_glass_when_the_image_is_formed_at_the_near_point_html_f9ca6a7.gif The angular magnification is, therefore, given by 4.4.3 Compound Microscope Compound Microscope is a kind of optical instrument that uses visible light and a lens system to magnify images of small samples. C:UsersGaryDesktopcompound micropound.png The lens L1 nearer to the object, called the objective, forms a real, magnified, inverted image I1 of an object O placed just outside its principal focus Fo. I1 is just inside the principal focus Fo of the second lens L2, called the eyepiece, which act as a magnifying glass and produces a magnified, virtual image I2 of I1. In normal adjustment, the final image I2 lies at the near point. Then the visual angle subtended by the final image to the eye is given by When the object of height h is placed at the near point and viewed unaided, the visual angle subtended by the object is given by Hence, the angular magnification is given by And since, the linear magnification is equal to the linear magnification of the objective x linear magnification of the eyepiece. (Giordano, 2011) 4.4.4 Refracting Astronomical Telescope Refracting Astronomical Telescope consists of two converging lenses; one is an objective with long focal length and the other an eyepiece with short focal length. The objective L1 forms a real, diminished, inverted image I1, of a distant object at its principal focus Fo since the rays incident on L1 from a point on such an object can be assumed parallel. The eyepiece L2 acts as a magnifying glass and forms a magnified, virtual image of I1 and, when the telescope is in normal adjustment, this image is at infinity. I1 must, therefore, be at the principal focus F2 of L2, hence F0 and F2 coincide. http://images.tutorvista.com/content/optics/astronomical-telescope-magnifying-power.jpeg From the above figure, we find that The visual angle subtended by the object is given by and the visual angle subtended by the object is given by, where h is the image height. Therefore, the angular magnification is For telescope in normal adjustment, the separation of the two lenses is the sum of the focal lengths. And this, the foci of the objective lens and the eye-piece must be at the same place. (Giordano, 2011) 4.4.5 Galilean Telescopehttp://www.transtutors.com/userfiles/image/ARUN/IMAGES/Gal.JPG Galilean Telescope consists of two lenses a converging objective of large focal length and a diverging eyepiece of small focal length The angular magnification is 5. Conclusion In this term paper, the concepts of geometric optics are included comprehensively such as law of reflection, refraction, formation of images in mirrors and lens, etc. The notion of a light ray and the scientific study of light are involved in a bid to illustrating the working principle of different mirror and optical instruments, such as various telescope, efficiently.

Character Analysis Of Anse Bun Essay -- essays research papers

Character Analysis of Anse Bundren Anse Bundren is an ugly old man. He is probably in his fifties or sixties. He is very ugly. He has terrible posture and a hump in his back. He looks like he never shaves in a scraggly way and his face is very wrinkled. It isn’t tan because he never spends much time in the hot sun. He has no teeth which is probably his most distinguishing characteristic. He used to be a tall man but even when he was young, he was beginning to show the signs of a hump. Addie comments on this in her chapter. She asked him if he had any womenfolks to make him stand up straight. There is not much background about Anse’s childhood or what it was like for him growing up but one can assume that his father and he share some similar traits. By the time he asked Addie to marry him, he was living on his own small farm alone. Anse has a shy side to him. He drove past Addie’s school teaching job several times before he got up the courage to talk to her. Apparently he went all out once he did get the courage and asked her to marry him the first time they ever spoke. He shied around this and did it subtly. When Addie asks him if he has any womenfolks, he says “That’s what I came to see you about.'; When Anse was twenty three he got sick and passed out while sweating. Since then he has come to believe that if he ever sweats again he will die. So therefore, he gets by without doing any hard work. He NEVER sweats because th...

Recovering Paul Ricoeurs Intervention in the Gadamer-Habermas Debate :: Philosophy Philosophical Essays

Recovering Paul Ricoeur's Intervention in the Gadamer-Habermas Debate ABSTRACT: In this paper I will examine a contemporary response to an important debate in the "science" of hermeneutics, along with some cross-cultural implications. I discuss Paul Ricoeur's intervention in the debate between Gadamer and Habermas concerning the proper task of hermeneutics as a mode of philosophical interrogation in the late 20th century. The confrontation between Gadamer and Habermas turns on the assessment of tradition and the place of language within it; the hermeneutical stance takes a positive stance, while ideologiekritik views tradition with a hooded-brow of suspicion, tantamount to "seeing tradition as merely the systematically distorted expression of communication under unacknowledged conditions of violence." In his own rescue operation, Ricoeur combines the reanimation of traditional sources of communicative action with the re-awakening of political responsibility towards a creative renewal of cultural heritage. His fusion or consensus adverts to specific sym bols of Western eschatology, viz., liberation, salvation, and hope. What will result if we juxtaposed Buddhist, Daoist and Hindu symbols of Non-being, Nature as transcendence and Intelligence, respectively? Preamble In this paper I wish to examine a contemporary response to an important debate in the "science" of hermeneutics — "the art of rightly understanding the speech, chiefly in written form, of another" (Schleiermacher, 1977). The 20th century has witnessed, what elsewhere has been termed, "a profound radicalisation of the understanding of texts" in asmuch as hermeneutics — the programmatic of interpretation and all that it had hitherto supposed about the nature and relation of text and its meaning — is itself problematised. The site of the contestation has been language, understood in the broadest possible sense of the medium that functions to convey meaning, textual and otherwise. A variety of responses maturing into formidable intellectual movements have emerged, and continue to be articulated, especially in philosophy, literary studies and the social sciences. As is well-known, this virtual explosion of theories of textual meaning and vastly differing models of lin guistic understanding, or of the semiological processes, during the intellectual ferment known as Modernism, has had considerable impact in as areas as far afield as architecture, the arts, postmodernism, feminist studies, psychoanalysis, cross-cultural and post-colonial discourses, indigenist jurisprudence and even on geography and ecology or the geo-sciences. I will here confine my inquiry to a significant thinker rather than cover any particular movement or movements. I have chosen to discuss Paul Ricoeur's intervention in the debate between Hans-Georg Gadamer and Jungen Habermas concerning the proper task or calling as it were of hermeneutics as a mode of philosophical interrogation in the late 20th century.
