3.Explain techniques that a law enforcement officer can use to modify the effects of stress - Essay Example Some of the effects of stress include, slow digestion, increasing heart rate, speeds up metabolism and blood pressure. An Officer likely to have the above named effects is a threat not only to the officer’s health, but to the public too (Williams, and Harris, 1998). A law enforcement officer may opt to use the slow and deep breathing technique. He/she should look for a comfortable and quite place with no distractions. The officer should locate one hand on the lower abdomen and the other on the upper chest. In using the lower hand, he/she should try to breath. After managing to breath, he/she should try to manage the rate of breathing by holding the breath. He/she should try out the exercise for several times until the body familiarizes with the practice. This is one way of fighting stress. It is a simple and mostly used to counteract effects of stress too (Williams and Harris, 1998). The muscle relaxation technique is also an option to modify the effects of stress. One should lie down in a comfortable place away from the noise. Then, shut the eyes and concentrate on breathing out slowly pausing a little before breathing again. Concentrate all the muscles in the left foot and hold for some seconds. Thereafter, release the muscle concentration after some time and do the same for the other foot. Later concentrate all the muscles in the left leg and relax, then repeat the same procedure in the right leg. The process should be carried out in every part of the body (Jacobson, 1938). For all kind of stress-related problems that any law enforcement officer faces, such as, muscle tension, depression, heart disease, digestive problems or chronic fatigue among other, it is certain that either of the two techniques must modify the effects of stress (Jacobson,

Walt Disney Co. V. Beijing Publishing Press Essay

Walt Disney Co. V. Beijing Publishing Press - Essay Example Although Beijing Publishing Press had entered into contract with and paid Maxwell which has intellectual property rights from Disney, it violated Disney IPR. The contract details form Disney did not give Maxwell the right to subcontract its intellectual properties to third parties, which means that the contract between Maxwell and Beijing was void. The fact that the contract was illegal makes it void. Disney enjoys copyright protection of its products from the Chinese law. Therefore, any third parties who wish to utilize its intellectual properties must enter into a contract with Disney. In this case, there existed no contract between Disney and Beijing Publishing. Before paying IPR, a party should conduct careful due diligence to assure that it is paying for enforceable IPR. This case illustrates concept in that Beijing Publishing Company had an obligation to carry out proper investigations to ascertain the legality of the contract with Maxwell Company and Children Press. The department of state copyright administration requires companies to conduct an inquiry and implement registration procedures with the relevant authorities before actual use of IPR. Although Beijing Publishing Company had exempted itself in the working agreement with the Children press, where it stated that Children press would bear any responsibilities arising because of non-registration with the copyright authority; it failed to ascertain that Children Press is not an independent legal person and thus had to bear the responsibility. Beijing Company has a lawsuit against Maxwell. The contract between Disney and Maxwell stated, â€Å"Disney Company licenses to Maxwell Comp any exclusive rights to publish and sell within China its publications based on Disney world characters.† The contract expressly states that the license given should not be granted to third parties (Shaffer, Agusti, and Earle 574). Beijing Publishing can sue Maxwell on the ground that it breached the initial contract, which led to it incurring damages. Champagne V. Wines Worth Group Ltd This case involves an Australian company by name Wines Worth Group against French Department of Champagne that sought an injunction to prevent Australians from â€Å"passing off† their wine as produced from France. French Department of Champagne filed on the basis that they own the trademark. A trademark is a distinctive sign used by businesses to speak a message to their consumers to specify the origin of the product and henceforth dictate the target markets. It is a name, word, phrase, logo, or symbol and the owners of

An analysis of the Caravan industry in Hull, United Kingdom - Essay Example Static caravans are used as holiday homes and they are kept stationary in various places. All these options available for holiday venture and thus individuals must make wise decisions depending on their needs. Most of the caravans are used on holiday places. In the United Kingdom, there are various holiday places where caravans are used. The most popular ones are Cleethopper, Skegness, mablethorpe, and hornsea. Caravanning activities are very popular in these places. Most of these places are found in Hull and that is why hull has become very popular with caravanning. Moreover, there are various caravan-manufacturing companies in Hull. The caravan manufacturers in hull include Willerby Holiday Homes Ltd, Burstner Ltd, Corona Caravans Ltd, and Coachman Ltd. Among these manufacturers, the major ones are Willerby Holiday Homes Ltd and Corona Caravans Ltd. The reason for this is the large market share the two companies have in the caravan industry. As showed above, Hull has several caravan manufacturers. Some manufacture static caravans while others manufacture movable caravans. The company that is popular for manufacturing static caravans in Hull is Willerby Holiday Homes Ltd. Corona Caravans Ltd on the other hand is very popular in Hull for manufacturing movable caravans. The models made by different manufacturers vary both in shape and in characteristic. The reason why the companies in this industry try do this is to increase their competitiveness in this volatile market. Productions of caravans that are different from those of other companies convert the competition in this industry to an indirect. This promotes the survival of these companies in the caravan industry. Caravan industry is the greatest employer in the United Kingdom offering more than two percent of the total workforce. The employees employed in this industry undertake various responsibilities from management to

Googling Out of Control - Essay Example In other types of industries, the Googley way of working could potentially spell disaster for sales and overall business success. This paper will show whether the Googley way of working is actually sustainable long-term for the company and will discuss whether or not this way of working could provide higher benefits for different companies in need of change to their organisational structures or systems and processes. Historical theorists such as Frederick Taylor believed in a scientific method for business in which people should be observed over a period of time and then determining, through these observational findings, which method of training is best for performing specialised jobs in the organisation (Bloisi, Cook and Hunsaker, 2006). Combined with the scientific approach, Taylor also viewed workers through a mechanistic standpoint, believing that workers were often inherently difficult and uncooperative and often lacked the ability to absorb knowledge and information successfully. This classical view of management is still at work in many different industries today which have strong leadership hierarchies where virtually all decision-making starts at the top and trickles down the organisation. Google has managed to break away from this classical type of management model where workers are heavily controlled and observed and has given their workers considerable autonomy in most of their own d ecision-making concepts and job roles. It may only be in an environment where change is constant and there is a need for flexible and rapid decision-making where this chaotic type of leadership concept is going to be successful. For example, many of the main global automakers are experiencing sales declines in their auto sales, especially noticeable in the United States. Automakers in this category such as Ford and General

Financial System of France Essay Example | Topics and Well Written Essays - 2000 words

Financial System of France - Essay Example French banking system is composed of approximately 450 banking business entities, which operate close to 40,000 branches. With this magnitude banking institutions, approximately 60 million people are considered as the banked segment. One of the defining characteristics of French banking system is the proximity of financial and non-financial institutions to the customers, which provide adequate banking services and products. Nonetheless, all organizations providing banking services operate under authorized establishments. Authorization of establishments defines the scope of banking activities. The establishments authorized include general-purpose credit institutions, investment service providers, and specialized credit institutions. All the commercial banks and other financial institutions within France are regulated and controlled by Banque de France, the French Central Bank. Linked to the European Central Bank, Banque de France has been effective in administering monetary policies and ensuring compliance amongst financial organizations. Some of the core functions of Banque de France are formulation and implementation of monetary and credit policies, issuance of currency, ensuring financial stability, monitoring French’s financial markets, and controlling all the foreign reserves. Banque de France is usually administered by a General Council having the responsibility of developing and carrying out all activities that relate to monetary policies. French financial (stock) market has primary and secondary markets. Primary markets provide vistas for introduction of new securities while secondary markets are involved in the actual trading. Paris Stock Exchange market had four markets prior to 2005; first, second, new, and free markets. The trading on stock had to be done across these four markets. Paris, Bruzelles, and Amsterdam Stock Exchange markets merged into Euronext Stock Exchange Market, which led to free market being subsisted and replacement of other markets by the Eurolist market. Due to increasing volume of transactions, Euronext Stock Market expanded to cover Portugal and United Kingdom in 2003 though still under the control of Euronext Paris. Currently, Euronext, having a volume of approximately US$1.9 trillion (Yahoo Finance) by trading, has all the French and foreign companies that subscribe their shares to the public. Importantly, Euronext through merger with New York Stock Exchange in 2006 led to the establishmen t of the current NYSE Euronext. Within Euronext, the main stock indices relate to either market or activity with the main one being the CAC 40 belonging to SBF 120. Amazingly, CAC 40 makes up 75% of all the stock exchange transactions. On the other hand, blue chips of CAC 40 such as Air France KLM, Arcelormittal, and AXA amongst others are indicated in the appendices. French financial market is composed

One of the Free

One of the Freedom Fighters; Dr. Martin Luther King, Jr. Essay Martin Luther King, Jr. was born on January 15, 1929. He was an American clergyman, activist, and prominent leader in the African-American Civil Rights Movement. He is best known for his role in the advancement of civil rights using nonviolent civil disobedience. A Baptist minister, King became a civil rights activist early in his career. He led the 1955 Montgomery Bus Boycott and helped found the Southern Christian Leadership Conference (SCLC) in 1957, serving as its first president. Kings efforts led to the 1963 March on Washington, where King delivered his I Have a Dream speech. On October 14 1964, King received the Nobel Peace Prize for combating racial inequality through nonviolence. In the next few years leading up to his death, he expanded his focus to include poverty and the Vietnam War. King was assassinated on April 4, 1968, in Memphis, Tennessee. He was awarded the Presidential Medal of Freedom in 1977 and Congressional Gold Medal in 2004; Martin Luther King, Jr. Day was established as a U.S. federal holiday in 1986. Hundreds of streets in the U.S. and beyond have been renamed in his honor. Here’s an excerpt from his famous speech â€Å"I have a dream†: I have a dream that one day this nation will rise up and live out the true meaning of its creed: We hold these truths to be self-evident, that all men are created equal. I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today! I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of interposition and nullification one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today! I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight; and the glory of the Lord shall be revealed and all flesh shall see it together.

Elasticity Experiment: Application of Hookes Law

Elasticity Experiment: Application of Hookes Law Nguyen Manh Tri Investigation of elasticity Introduction General statement Any string that able to stretch and come back its original length can be considered as a spring. Each spring has constant of elasticity (stiffness) that depends on its material. A simple spring generally is made from metal. Background Elastic forces of the springs appear at the ends of the springs and material effect on the contact or association with it as it is deformed (Elert, 1998). The direction of elastic force counters the direction of the external force causing deformation. Specifically, when stretched, the elastic force of the spring towards the axis of the spring on the inside; even when compressed, the elastic force of the spring axis oriented outwards. The most popular law of elasticity is Hooke’s law. When a force is applied to an elastic object, the object will be stretched. A change in length à ¢Ã‹â€ Ã¢â‚¬  l is formed. In the elastic limit, the magnitude of the elastic force of the spring is proportional to the deformation of the spring. Hooke’s law can be expressed as = k () where k is a constant value which shows the stiffness of the object (BelenkiÄ ­, Salaev and SuleÄ ­manov, 1988). The k value has unit of newton per meter. A spring of length l1 is hung up by a bracket as shown in figure 1. If a mass is applied to the other end the spring, the spring will be stretched, resilient until all the energy is gone and form a new length l2. Then the system is balanced, the applied force, the weight of the mass, must equal the restoring force Mg = k(l2 – l1) = kà ¢Ã‹â€ Ã¢â‚¬  l Figure 1 Mathematically, Mg = k can be written as à ¢Ã‹â€ Ã¢â‚¬  l = [1.0] Equation [1.0] also can be performed as a linear equation (Treloar and Dunn, 1974) y = mx where y is à ¢Ã‹â€ Ã¢â‚¬  l and x is M. Then if we hang more and more weights for the spring and measure the length à ¢Ã‹â€ Ã¢â‚¬  l for each, the gradient of the graph is (Bbc.co.uk, 2014). Consequently, we can find the constant value k by calculating the gradient. For rubber or steel wire rope elastic force only when external forces are stretched. In this case the elastic force is called tension. Tension set point and direction like elastic force of the spring. For the contact surface is deformed when pressed against each other, with the elastic force perpendicular to the contact surface. Aims To determine the constant of elasticity of several different springs To find out the elastic limit. Hypothesis There are number of factors which affect the springs’ constant. One of these factors is the types of material, which makes the stiffness of springs different. Hookes law is accurate with simple objects such as springs. With material such as rubber or plastics, the dependence between the elastic forces in the deformation could more complicate (BelenkiÄ ­, Salaev and SuleÄ ­manov, 1988). In essence, the elastic interaction forces between molecules or atoms, i.e. the electromagnetic force between electrons and protons inside the elastic material. When the large deformation to a certain value, the elastic force does not appear again, and this value is called the elastic limit, if you exceed the time limit elastic deformation material will not be able to return original shape after impact not deform more. Figure 2: Elastic limit Method and Materials Figure 3: Experimental set-up Method The experiment was set up as shown in figure 3. The retort stand was placed firmly on the table. A spring was attached to the retort stand. The length of the spring (l1) in rest state was measured (using ruler) and recorded. The mass hanger (10 grams) was hung up the other end of the spring. New length of the spring (after applied the mass hanger) was measured (using ruler) and recorded. The change of length of the spring was calculated and recorded. One set of data was obtained afterwards. A weight was placed on the mass hanger. New length of the spring (after applied the weight) was measured (using ruler) and recorded. The change of length of the spring was calculated and recorded. Another set of data was obtained afterwards. Another weight was placed (20 grams total) and step 8 was then repeated. Step 9 was repeated until no weight left. 8 other sets of data were obtained afterwards. Steps 3 to 10 were repeated for the new springs (the remaining 2 springs). Finally, 30 sets of data were obtained (10 sets each spring). Results Table 1: First spring results l1 for the first spring = 13 mm M (g) l2 (mm) à ¢Ã‹â€ Ã¢â‚¬  l = l2 – l1 (mm) 10 14 1 20 16 3 30 18 5 40 20 7 50 21 8 60 24 11 70 25 12 80 25 12 90 28 15 100 31 18 Table 2: Second spring results l1 for the first spring = 20 mm M (g) l2 (mm) à ¢Ã‹â€ Ã¢â‚¬  l = l2 – l1 (mm) 10 20 0 20 20 0 30 22 2 40 24 4 50 28 8 60 32 12 70 35 15 80 39 19 90 42 22 100 46 26 Table 3: Third spring results l1 for the first spring = 20 mm M (g) l2 (mm) à ¢Ã‹â€ Ã¢â‚¬  l = l2 – l1 (mm) 10 20 0 20 20 0 30 20 0 40 22 2 50 24 4 60 27 7 70 32 12 80 34 14 90 38 18 100 40 20 Figure 4: Change of length against mass for the first spring Figure 5: Change of length against mass for the second spring Figure 6: Change of length against mass for the third spring As shown in figure 4, 5, and 6 three straight lines are formed and show a trend that the weight increases with increasing à ¢Ã‹â€ Ã¢â‚¬  l. Discussion Calculation – Results from part 1 experiment From figure 4, y = 0.1834x 1 therefore, gradient (m1) = 0.1834 mm/g From figure 5, y = 0.3062x 6 therefore, gradient (m2) = 0.3062 mm/g From figure 6, y = 0.2774x 8 therefore, gradient (m3) = 0.2774 mm/g Since the spring constants are measured by gradient (m) = therefore, k = We also have g = 9.81 (ms-2), k1 = = = 53.50 mmgs-2 k2 = = = 32.04 mmgs-2 k3 = = = 35.36 mmgs-2 Results analysis Because of above factors, some points such as (10; 0) from figure 5 and (10; 0), (20; 0) from figure 6 are not involved in the trend line. The smallest share of the ruler is 1mm so it is unable to distinguish the à ¢Ã‹â€ Ã¢â‚¬  l between 0 gram and 10, 20 grams. Parallax error also is a cause of these strange points. Because of the very first à ¢Ã‹â€ Ã¢â‚¬  l are too small, wrong angles between eyes and ruler may cause the errors of these points. Y-intercepts for 3 springs are -1, -6 and -8 respectively. The y-intercept -1 is a very small value and is able to show the accuracy of the experiment. The others two are much bigger because of different constant k values of springs (53.50, 32.04 and 35.36 respectively). For the first spring, which has k value are 53.50, it is much easier to distinguish different à ¢Ã‹â€ Ã¢â‚¬  l values for the first weights. Consequently, there is no strange point is recorded for this spring, all the points involves in the trend line. For the last two springs, k values are almost half of the first one and it hard to distinguish à ¢Ã‹â€ Ã¢â‚¬  l values for the first weights. This is the reason why strange points are recorded and do not involve in the trend lines. Consequently, the trend lines of these springs tend to go far away the origins when pass the y-axis. Errors analysis and other factors affecting the experiment Parallax error Parallax error is the most popular error in physics (Aphysicsteacher.blogspot.co.uk, 2009). Because this experiment contain many small values (smaller than mm), so parallax error may cause many wrong data and strange points. The concept of parallax error is related to the term parallax. For instance, in figure 7, different positions of eyes result in 3 values for the measurement (two of them are wrong values).Soparallax is the change in the apparent position of an object when the position of the observer changes. Figure 7: Example for parallax error Consequently, the accuracy of the measurement depends on the angle between eyes and ruler. Because of this error, à ¢Ã‹â€ Ã¢â‚¬  l values are slightly greater or smaller and results in slightly change of k values. To minimize this error, a pointer can be used to help read the scale on the ruler and the scale had to be viewed at eye level (Cyberphysics.co.uk, 2014). Temperature Materials’ thermal expansion coefficient ÃŽ ± and stiffness are connected. This connection is mathematically formulated as ÃŽ ± = where the ÃŽ ³G is a constant value (0.4 G ÃŽ ± is a constant value so if temperature is increased, density increases and stiffness increases; if temperature decreased, density decreases and stiffness decreases. Accuracy of ruler The smallest share of plastic ruler is 1mm. As mentioned above, there are many small values so it is necessary to consider the error percentage caused by accuracy of ruler. Improvement To minimize parallax error, a pointer can be used to help read the scale on the ruler and the scale had to be viewed at eye level (Cyberphysics.co.uk, 2014). To minimize temperature error, the air temperature should be held on standard (room temperature – 298K). To minimize accuracy of ruler error, an instrument which has small length accurately should be used (Mohindroo, 2006). The accuracy of the result can be greatly improved. Conclusion The constant of elasticity of 3 springs are 53.50, 32.04 and 35.36 respectively by calculating as mentioned above. Summarizing the three points, this experiment has met the objectives stated in the introduction. Knowledge about elasticity and constant of elasticity has learnt through this study. It is unable to find out the elastic limits because if keep adding weights until the springs can stretch more, the springs will be damaged and will not be able to come back its original shapes (Sadd, 2005). There are some factors are mentioned above, which are affect the results of this experiment. These factors do not change the results significantly (strange points were recorded only for the very first weights). Reference Bbc.co.uk, (2014). BBC GCSE Bitesize: Hookes Law.
