Business Organasation - Essay Example The creation of an LLP’ requires the minimum of a general partner and a limited partner. The duties, rights and obligations of these members are similar in status to those of the partners in a general partnership. Because of the limited amount of contribution exposed to the risks of investment, the limited partners are considered more as investors than partners; in addition to the fact that they are not required to participate in the management of the business (LeRoy & Jentz, 2009). After the 20 July 2000, when the Limited Liability Partnership Act 2000 was accorded the Royal Assent, the LLP’s were introduced as the latest business vehicle across the United Kingdom beginning 6 April 2001. This date was during the Inland Revenue tax year associated with the taxation structure adopted for LLP’s. Consequently, the increase in limited liability partnerships in entirely linked with the unique tax advantages available for the partners/members. Profits and losses can be directly passed with certain limitations to the partners because the limited partnership is not taxed as a separate legal entity. ... According to Arthur and Sheffrin (2003, p. 183), the LLP is made of distinct partners due to the statutory rights and responsibilities accorded to both limited and general partners. However, the difference between the rights and responsibilities of general partners in a limited partnership against those of a general partnership should be stipulated in the statute and the partnership agreement. Because of the ‘limited’ nature of limited partners, general partners become personally responsible for the obligations and debts of the company (Wood, 1997). The limited partners of a LLP are entitled to specific rights and responsibilities. Considered a ‘limited’ party, the limited partner enjoys fewer rights and hence has fewer responsibilities than the general partners. Their limited liability means that their risk is limited to the investment amount in the LLP. Unlike other partners, the interest of a limited partner is perceived as personal property. For instance if the partnership owns land, the limited partner will have an interest in the limited partnership and not the title to the assets. According to Emerson (2009) partners in a general partnership are allowed to participate in the management of the company; while limited partners attempting to participate in the control of the partnership face the risk of losing his/her limited liability status. According to the Revised Limited Partnership Act, specific responsibilities and powers are outlined through which a limited partner will lose their limited liability. Some of which include attending partners’ meetings; proposing or pursuing a derivative action in place of the company; acting as surety or representing a guarantee for the company;

Inequality in the UK its effect on the national economy Essay

Inequality in the UK its effect on the national economy - Essay Example Why should economists care about inequality in the distribution of incomes? Poverty and economic inequality are intimately bound with one another both as a policy or an analytical issue. Economic well-being and income distribution are related as demonstrated in the societal understanding of justice and human rights, and, therefore, render economic equality an intrinsic value. High levels of economic equity are associated with desirable social outcomes especially in the realms of health and crime (Andrew and Meen2006). The EU defines poverty as living on less than half the average national income, as such, irrespective of the average income, the greater the income inequality, the higher levels of poverty in a country. The definition of the extent of poverty depends on both the level of a society’s income and the distribution of income. Therefore, societal standards or norms of essential needs in a society are determined by the middle class (Brueckner, Thisse and Zenou 1999). In the case of two societies where the bottom segments have the same level of income, poverty is more prevalent in the in the society where income is more unequally distributed. The bottom quintile of the unequal society will be more isolated from the middle quintile and will, therefore, be further from meeting the standards of that society. As a result, more members of this bottom quintile will be stuck in poverty (Beroube 2005).

Proposed System for Plagiarism Detection

Proposed System for Plagiarism Detection Chapter 3 The Proposed System Introduction This chapter introduces ZPLAG as proposed system, and its most important design issues are explained in details. It is very easy for the student to find the documents and magazines using advanced search engines, so the problem of electronic thefts is no longer local or regional, but has become a global problem occurring in many areas. Due to the Hugging of information, and correlation networks, the discovery of electronic thefts is a difficult task, and the discovery of the thefts started in the Arabic language and the most difficult task no doubt. And in light of the growing e-learning systems in the Arab countries, this requires special techniques to detect thefts electronic written in Arabic. And although it could use some search engines like Google, it is very difficult to copy and paste the sentences in the search engines to find these thefts. For this reason, it must be develop a good tool for the discovery of electronic thefts written Arabic language to protect e-learning systems, and to facilitate and accelerate the learning process, where it can automatically detect electronic thefts automatically by this tool. This thesis shows, ZPLAG, a system that works on the Internet to enable specialists to detect thefts of electronic texts in Arabic so it can be integrated with e-learning systems to ensure the safety of students and research papers and scientific theses of electronic thefts. The thesis also describes the major components of this system, including stage outfitted, and in the end we will establish an experimental system on a set of documents and Arabic texts and compared the results obtained with some of the existing systems, particularly TurnItIn. The chapter is organized as follow; Section 3.2 presents an overview of the Arabic E-Learning, Section 3.3 presents and explains the General Overview of the Proposed System, Section 3.4 explains in details the system architecture of the proposed system ZPLAG. Section 3.5 gives a summery for this chapter. General Overview of the Proposed System The proposed system consists of three different phases namely; (1) Preparation phase, (2) Processing phase, and (3) Similarity detection phase. Figure 3.1 depicts the phases of the proposed system. Figure 3.1 Proposed system phases Preparation Phases: this phase is responsible for collecting and prepares the documents for the next phase. It consists of five modules: text editor module, check language module, check spelling module, check grammar module, and Sentences analysis module. Text editor module allows the user to input a text or upload a text file in document format, these files can be processed in the next phase. The check language module is responsible for checking the input file written language, If it is an Arabic language then use Arabic process, or English language then use English process. The check spelling module use to check the words are written correct or there is some misspelling. This phase consists of three modules explained as follows: Tokenization: break up the input text as some token . SWR: remove the common words that appear in the text but carry little meaning. Rooting: is the process of removing: (prefixes, infixes, or/and suffixes) from words to get the roots or stems of this word Replacement of Synonym: words are converted to their synonyms. Similarity detection Phases: It is consists of three modules Fingerprinting, documents representation and similarity detection, this phase discussed as follows: To calculate fingerprints of any document, first cut up the text into small pieces called chunks, the chunking method that responsible for cutting up the text will be determined [12]. A unit of chunk could be a sentence or a word. In case of chunking using sentences called sentence-based, the document can be cutted into small chunks based on ‘C’ parameter. For example, a document containing sentences ds1 ds2 ds3 ds4 ds5, if C=3 then the calculated chunks will be ds1 ds2 ds3, ds2 ds3 ds4, ds3 ds4 ds5. For example, a document containing words dw1 dw2 dw3 dw4 dw5, if C=3 then the calculated chunks will be dw1 dw2 dw3, dw2 dw3 dw4, dw3 dw4 dw5. The chunking using Word gives higher precision in similarity detection than the chunking sentence. The Architecture pf Proposed System The following properties should be satisfied by any system detecting plagiarism in natural language: Insensitivity to small matches. Insensitivity to punctuation, capitalization, etc. Insensitivity to permutations of the document content. The system main architecture of ZPLAG is illustrated in Figur1. Preparation: text editor, check language, check spelling, and check grammar. Preprocess: synonym replacement, tokenization, rooting, and stop-word removal. Fingerprinting: the use of n-gram, where the user choses the parameter n. Document representation: for each document, create a document tree structure that describes its internal representation. Selection of a similarity: use of a similarity metric to find the longest match of two hash strings. As mentioned in the previous section, the system architecture breakdown contains three main phases. Each phase will be composed to a set of modules in terms of system functionality. The following section contains the description of each phase and its modules in details. 3.4.1 The Preparation Phase The main task of this phase is to prepare the data for the next phase. It consists of text editor module, check language module, check spelling module and check grammars module. 3.4.1.1. Text editor Module Figure 3.2, illustrates text editor module. The users of the text editor module are faculty members and students, where the users need a text area to upload their files, so the brows helps for file path to make it easy for the users, After that check file format is very important , because the service upload files with doc or docx format, then after the user upload the file , the text editor module save the file in the database. Figure 3.2 text editor module 3.4.1.2 Check Language Module The raw text of the document is treated separately as well. In order to extract terms from text, classic Natural Language Processing (NLP) techniques are applied as. Figure 3.3 illustrates Check Language module and its functions: from the system database, whereas all the files are stored, the check language module bring the file and read it, then check for language either Arabic , English or combo (both Arabic and English), After that mark the document with its written language and save the file again in the system database. Figure 3.3 check language module 3.4.1.3 Check Spelling Module Figure 3.4 illustrates Check spelling module and its functions: after bringing the document from the system database, whereas all the files are stored, the check spelling module read the file, and use the web spelling checker, then the check spelling module make all the possible replacements for the words in false spelling check , After that save the file again in the system database. Figure 3.4 check spelling module 3.4.1.4 Check Grammars Module For English documents, Figure 3.5 illustrates Check grammar module and its functions: after bringing the document from the system database, whereas all the files are stored, the check grammar module read the file, and use the web grammar checker, After that the check grammar module mark the sentences with the suitable grammar mark and save the file again in the system database. Figure 3.5 check grammar module 3.4.2 The processing Phase 3.4.2.1 The Tokenization Module In the Tokenization module : after bringing the document from the system database, whereas all the files are stored, the Tokenization module read the file, and brake down the file into paragraphs, after that brake down the paragraphs into sentences, then brake down the sentence into words. After that save the file again in the system database. 3.4.2.2 The Stop Words Removal and Rooting Module The raw text of the document is treated separately as well. In order to extract terms from text, classic Natural Language Processing (NLP) techniques are applied as. Figure 3.6 illustrates Stop Words Removal and rooting module and its functions: Figure 3.6: SWR and Rooting module SWR: Common stop words in English include: a, an, the, in, of, on, are, be, if, into, which etc. Whereas stop words in Arabic include: Ù†¦Ãƒâ„¢Ã¢â‚¬   , Ø ¥Ãƒâ„¢Ã¢â‚¬Å¾Ãƒâ„¢Ã¢â‚¬ ° , Ø ¹Ãƒâ„¢Ã¢â‚¬   , Ø ¹Ãƒâ„¢Ã¢â‚¬Å¾Ãƒâ„¢Ã¢â‚¬ ° , Ù Ãƒâ„¢Ã…   etc. These words do not provide a significant meaning to the documents . Therefore, they should be removed in order to reduce ‘noise’ and to reduce the computation time. Word Stemming: it will be changed into the word’s basic form. 3.4.2.3 Replacement of Synonym Replacement of Synonym: It may help to detect advanced forms of hidden plagiarism. The first synonym in the list of synonyms of a given word is considered as the most frequent one. 3.4.3 The Similarity Detection Phase 3.4.3.1 The Fingerprinting Module It is consists of three modules Fingerprinting, documents representation and similarity detection, this phase discussed as follows: To calculate fingerprints of any document, first cut up the text into small pieces called chunks, the chunking method that responsible for cutting up the text will be determined [12]. A unit of chunk could be a sentence or a word. In case of chunking using sentences called sentence-based, the document can be cutted into small chunks based on ‘C’ parameter. For example, a document containing sentences ds1 ds2 ds3 ds4 ds5, if C=3 then the calculated chunks will be ds1 ds2 ds3, ds2 ds3 ds4, ds3 ds4 ds5. In case of chunking using word called a word-based chunking, the document is cutted into small chunks based on ‘C’ parameter. For example, a document containing words dw1 dw2 dw3 dw4 dw5, if C=3 then the calculated chunks will be dw1 dw2 dw3, dw2 dw3 dw4, dw3 dw4 dw5. The chunking using Word gives higher precision in similarity dete ction than the chunking sentence. ZPLAG is based on a word-based chunking method: in every sentence of a document, words are first chunked and then use a hash function for hashing. 3.4.3.2 The Document Representation Module Document representation: for each document, create a document tree structure that describes its internal representation. 3.4.3.3 The Similarity Detection Module A tree representation is created for each document to describe its logical structure. The root represents the document itself, the second level represents the paragraphs, and the leaf nodes contain the sentences. Summary Being a growing problem, The electronic thefts is generally known as plagiarism and dishonesty academic and they constitute a growing phenomenon, It should be known that way to prevent its spread and preserve the ethical principles that control the academic environments, with easy access to information on the World Wide Web and the large number of digital libraries, electronic thefts have become one of the most important issues that plague universities and scientific centers and research. This chapter presented in detailed description of the proposed system for plagiarism detection in electronic resources and its phases and its functions.

Thomas Edison :: biography biographies bio

Thomas Edison was born Febuary 11, 1847 in Milan Ohio. He was the youngest of seven siblings, and did not learn to talk until he was nearly four. At the age of seven Edison spent three months in school until his mother took him out of school and home schooled him. When Tom turned twelve the young entrepreneur became a railroad newspaper boy. He would ride rail cars selling candy, newspapers, fruits, and vegetables. Soon after Edison began working on the railroads he became practically deaf. There are several theories on what happened to make the inventor deaf one of the widest spread beliefs is that Edison lost his hearing when a conductor boxed his ears after Edison accidentally set fire to a train car. Edison said that he lost his hearing when a brakeman caught Edison by his ears to stop Edison from falling off the train. Regardless of what happened Edison couldn't hear out of his left ear and was about eighty percent deaf in his right ear. One day before getting on a train fourteen year old Edison noticed a todler with his back turned to an oncoming train. Tom reacted quickly throwing himself and the toddler off the tracks in the nick of time. The three year olds dad trained Edison to operate a telagraph machine as a reward. By the age of sixteen Edison had mastered this skill and left home. He moved to Boston, however a year and a half after he started working there he was forced to quit because his employer accused him of "not concentrating on his primary responsibilities, and doing to much moonlighting." Edison was moved to New York where he arrived practically broke. Three weeks after arriving in New York Edison had a job that paid much better than his Boston employer. The story goes that Edison who was broke and on the verge of starving came across a panicing broker. The broker was freaking out because an important stock ticker had broken. Edison tinkering paid off when he quickly fixed the ticker. The broker hired Edison on the spot as the company's repair man for $300.00 a month a very impresive amount in 1869. A year later Edison became a rich man when a company paid $40,000 for an improved stock ticker. Edison had expected no more than $5,000. After getting his first check for that much money Edison was at a loss for what to do.

An investigation on the development of car safety and the importance of airbags Essay

Chemistry experiment to simulate the inflation of an airbag in case of a car crash Aim Our aim is to create a chemical reaction to demonstrate the rapid inflation used in automobiles. The inflation of an airbag is a very fast reaction, and the typical reactants used are a mixture of Calcium carbonate (CaCO3), Potassium nitrate (KNO3) and Silicon dioxide. When a car crash occurs a sensor in the car’s airbag triggers the reaction that will save the drivers life if the speed at which he is moving is greater than 16-24 km/h-1. The nitrogen has to be produces more quickly than the driver hitting the steering wheel. The entire reaction is completed in less than 1/25 of 1 sec, because of the danger of this reaction, to demonstrate in a similar way the reaction that takes place in an airbag we have chosen to inflate a balloon using the gas obtained by the reaction of a metal acid to produce sodium carbonate. Equation Ca(s) + 2HCl(aq) = Ca(aq) + (g) + O(l) Materials -Conical Flask -Cork with delivery tube -heat mats -spatula -chemicals (baking soda) – goggles (safety glasses) Procedure à ¯Ã‚ ¿Ã‚ ½ Gather all apparatus needed for the entire experiment à ¯Ã‚ ¿Ã‚ ½ Set up all apparatus à ¯Ã‚ ¿Ã‚ ½ Pour CaCo3 into the conical flask à ¯Ã‚ ¿Ã‚ ½ Add the HCl to the solution already in the conical flask à ¯Ã‚ ¿Ã‚ ½ Cover the flask with a cork delivery tube which will then allow to blow up the balloon à ¯Ã‚ ¿Ã‚ ½ Observe the reaction Conclusion Our experiment was successful in proving the function of an airbag of a car. Our experiment aimed to demonstrate the safety of the passengers of an automobile, through the use of an airbag. For our chemistry experiment we chose to adapt the airbag inflation to our IB program syllabus, hence by doing an experiment similar to the one we had already successfully completed during the school year. was the element produced that mainly inflated the balloon, the reaction took place almost immediately. Hence, we have experimented the chemical reaction of a metal acid that produced Sodium Carbonate and inflated a balloon, the reaction was similar to the inflation of an airbag, proving the same chemistry principles. Research Question: How airbags managed to improve automobile safety. Introduction: The development of airbags began with the idea for a system that would save automobile drivers and passengers in a car accident, whether they were wearing their seat belts or not. Nowadays, airbags are compulsory in new cars and are designed to act as a supplementary safety device in addition to a seat belt. Airbags were invented in 1953. The automobile industry started in the late 1950’s to research airbags and soon discovered that there were many difficulties in the development of an airbag. Crash tests showed that for an airbag to be useful as a protective device, the bag must deploy and inflate within 40 milliseconds. The system must also be able to detect the difference between a severe crash and a minor fender-bender. These technological difficulties slowed the airbag creation process of 30 years, and in fact, it was in the mid 1980s that airbags started to be installed in all cars produced. In recent years, increased reports in the media concerning deaths or serious injuries due to airbag deployment have led to a national discussion about the usefulness and â€Å"safety† of airbags. Questions are being raised as to whether airbags should be mandatory, and whether their safety can be improved. However, as Graph 1 and 2 demonstrate, airbags have saved lives and have lowered the number of severe injuries. Graph 1 This bar graph shows that there is a significantly higher reduction in moderate to serious head injuries for people using airbags and seat belts together than for people using only seat belts. Graph 2 Deaths among drivers using both airbags and seat belts are 26% lower than among drivers using seat belts alone. An airbag must be able to deploy in a matter of milliseconds from the initial collision impact. It must also be prevented from deploying when there is no collision. Hence, the first component of the airbag system is a sensor that can detect head-on collisions and immediately trigger the airbag’s deployment. One of the simplest designs employed for the crash sensor is a steel ball that slides inside a smooth bore. The ball is held in place by a permanent magnet or by a stiff spring, which inhibit the ball’s motion when the car drives over bumps or potholes. However, when the car decelerates very quickly, as in a head-on crash, the ball suddenly moves forward and turns on an electrical circuit, initiating the process of inflating the airbag. Once the electrical circuit has been turned on by the sensor, a pellet of sodium azide (NaN3) is ignited. A rapid reaction occurs, generating nitrogen gas (N2). This gas fills a nylon or polyamide bag at a velocity of 150 to 250 miles per hour. This process, from the initial impact of the crash to full inflation of the airbags, takes only about 40 milliseconds (Movie 1). Ideally, the body of the driver (or passenger) should not hit the airbag while it is still inflating. In order for the airbag to cushion the head and torso with air for maximum protection, the airbag must begin to deflate as the body hits it. Otherwise, the high internal pressure of the airbag would create a surface as hard as stone, a device that wouldn’t result useful to the passenger or driver. Evaluation: The kinetic theory of gases assumes that gases are ideal, thus that there are no interactions between molecules, and the size of the molecules is small compared to the free space between the molecules, but molecules are as a physical body that moves continually through space in random directions. In a microscopic view, the pressure exerted on the walls of the container is the result of molecules colliding with the walls, and hence exerting force on the walls (Graph 3). When many molecules hit the wall, a large force is distributed over the surface of the wall, which gives pressure. An important fact derived from the kinetic theory of gases shows that the average kinetic energy of the gas molecules depends only on the temperature. Since average kinetic energy is related to the average speed of the molecules (EK = mu2 / 2, where m=mass and u is the average speed), the temperature of a gas sample must be related to the average speed at which the molecules are moving. Thus, we can view temperature as a measure of the random motion of the particles, defined by the molecular speeds. This implies that there must be a range (distribution) of speeds for the system. In fact, there is a typical distribution of molecular speeds for molecules of a given molecular weight at a given temperature, known as the Maxwell-Boltzmann distribution (Graph 3). This distribution was first predicted using the kinetic theory of gases, and was then verified experimentally using a time-of-flight spectrometer. As shown by the Maxwell-Boltzmann distributions in Graph 3, there are very few molecules traveling at very low or at very high speeds. The maximum of the Maxwell-Boltzmann distribution shows the intermediate speed at which the largest number of molecules are traveling. As the temperature increases, the number of molecules that are traveling at high speeds increases, and the speeds become more evenly distributed in the curves. Graph 3 The Maxwell-Boltzmann distribution can be shown graphically as the plot of the number of molecules traveling at a given speed versus the speed. As the temperature increases, this curve broadens and extends to higher speeds. As seen in Graph 3, there is a unique distribution curve for each temperature. Temperature is defined by a system of gaseous molecules only when their speed distribution is a Maxwell-Boltzmann distribution. Any other type of speed distribution rapidly becomes a Maxwell-Boltzmann distribution by collisions of molecules, which transfer energy. Once this distribution is achieved, the system is said to be at thermal equilibrium, and hence has a temperature. When a body hits the steering wheel directly, the force of this impact is distributed over a small area of the body, resulting in injuries to this area. The area that hits the steering wheel is shown in red. When a body is restrained by an airbag, the force of the impact is distributed over a much larger area of the body, resulting in less severe injuries. The area that hits the airbag is shown in orange. Conclusion:The law of inertia, is demonstrated in a car collision and it is Newton’s first law which states that: objects moving at a constant velocity continue at the same velocity unless an external force acts upon them. When a car stops suddenly, as in a car incident, a body inside the car continues moving forward at the same velocity as the car was moving prior to the collision, because its inertial tendency is to continue moving at constant velocity. However, the body does not continue moving at the same velocity for long, but rather comes to a stop when it hits some object in the car, such as the steering wheel or dashboard. Thus, there is a force exerted on the body to change its velocity. Injuries from car accidents result when this force is very large. Airbags protect you by applying a restraining force to the body that is smaller than the force the body would experience if it hit the dashboard or steering wheel suddenly, and by spreading this force over a larger area. For simplicity, in the discussion below, we will consider only the case of a driver hitting the steering wheel. If there is a restraining device as an airbag, the force of impact decreases, hence, the airbag reduces the rate of deceleration. Therefore, the force on the body is smaller and fewer injuries result. When an airbag restrains the body, the body exerts an equal and opposite force on the airbag. Unlike the immovable steering wheel, the airbag is deflated slowly. This deflation can occur because of the presence of vents in the bag. The force exerted by the body pushes the gas through the vents and thus deflates the bag. Because the gas can only leave at a certain rate, the bag deflates slowly. Additionally, airbags help reduce injuries by spreading the force over a larger area. If the body crashes directly into the steering wheel, all the force from the steering wheel will be applied to a localized area on the body that is the size of the steering wheel, from which a serious injury can form. However, when the body hits an airbag, which is larger than a steering wheel, all the force from the airbag on the body will be spread over a larger area of the body. Therefore, the force on any particular point on the body is smaller. Hence, less serious injuries will occur, this will also help to save the driver’s and passenger’s life. This is how a simple chemical equation avoids the deaths of millions. Physic’s Experiment Investigating safety on cars Introduction As cars became increasingly powerful and fast, rate of incidents increased exponentially and, usually more violent. This meant, over the years, a constant research and development of new security measures, and even nowadays more and more new systems are introduced every day. This development gave birth to what we now consider to be the basic requirements of any safe car, such as seat belts, air bags and crumple zones. Crumple zones The structures that in cars are commonly known as crumple zones are areas placed on the front and usually on the rear of a vehicle that are designed to absorb energy during impact in a predictable and controlled way. In the late 1950s, the general population still believed that the stronger the structure of a car, the safer that car would be during an incident. Actually, however, this kind of construction criteria proved to be fatal to most passengers. This is because during a collision all the energy of the impact went directly to the vehicle and onto the passengers. In 1967, the Mercedes Heckflosse was the first mass production car in the world to feature â€Å"crumple zones† and a safety cage. In order to fit appropriate crumple zones, the truck was made almost 50% bigger. Nowadays car featuring crumple zones and rigid cabs are standard safety requirements in almost every car made throughout the world. The fact that a car that crushes more easily protects its passengers more than a car that does not crush at all, may seem strange, but, in fact, the reason for this seem obvious when considering the physics behind it. Newton’s first law states that a body will remain at rest or continue travelling at uniform motion (constant velocity) unless a force is acted on it. Therefore, in a situation in which a car is impacting with a wall, if a vehicle is travelling at 70 km/h, the passengers inside are doing the same, and when the vehicle collides with the wall and comes to a sudden stop, the passengers’ bodies will continue going in the same direction at the same speed, 70 km/h. As stated in the law, these bodies will keep on moving forward until they themselves collide with a part of the car or with another passenger. Even when the human body comes to rest in this kind of incident, its internal organs slam against each other and against bones. This will, of course cause, injuries to the passengers and sometimes even death. Newton’s second law of motion states that: The law conveys that as the time taken by the car to arrive to complete rest increases, the force transferred to the car and, therefore its passengers, will be decreased. On the other hand, if the amount of time to reach complete halt is decreased, the force experienced will be greater. Crumple zones are specifically designed in order to crush, absorbing part of the force of the collision. The force of the collision is given out during the impact in the form of heat, sound and in from of mechanical work done on the crumple zone. The front (and rear) part of the car acts as a cushion and it is able to increase the time taken to reach complete halt and, hopefully, save the passengers’ lives. However crumple zones only work provided there is no intrusion on external elements, like the engine, in the rigid cage. This concept can be easily explained thought a simply example. Take for instance two object, the first is a solid steel block, while the second is an aluminium can. When the solid steel block (or car with no crumple zones) impacts with the wall, the wall does not move and, instead, exerts an equal magnitude and opposite direction force on the block. This causes the block to bounce off the wall in an elastic manner, conserving almost all its initial kinetic energy (EK) and, therefore, experiencing a large force. On the other hand when considering the aluminium can, the situation is different. When an aluminium can (or a car with crumple zones) impacts with a wall, it does not conserve all of its initial kinetic energy (EK). This is because, instead of just bouncing off, some of the kinetic energy is transformed into mechanical work, heat and sound , during the squashing of the crumple zones. The result is a smaller force acted on the can. The action of crumple zones increases the time of collision and lessens the amount of force experienced by the aluminium can. Specific materials As seen in the previous section, the material with which different parts of the vehicle are built are of primary importance. Depending on how we want specific parts of the car to behave, specific material must be chosen. For instance, crumple zones are expected to crush easily, while the inner rigid cage is supposed to withstand higher forces without braking. Based on this information we can determine that the best material to build a crumple zone is an easily bendable metal like aluminium, instead for the rigid cage, a much harder alloy like steel. Alloys are partial or complete solid solutions of one or more elements (metallic or/and non-metallic) in a metallic lattice. Alloys usually present different properties from those of the elements composing them. Alloying one metal with one or more metals or non-metals often improves the properties of the starting elements. For instance, when considering steel we can see how this alloy is stronger than its primary element, iron (Fe). Even though physical properties, such as density, reactivity, electrical and thermal conductivity, of the alloy does not differ inn great amount from those of its constituent elements, engineering properties such as tensile strength and shear strength can differ considerably. The tensile strength of a material is the maximum amount of tensile stress (measured in Newton) that it can tolerate before it tears to parts. The shear strength, instead, is the ability of the material to resist shear stress. The increase in both tensile strength and shear strength are usually due to the sizes of the atoms in the alloy. Larger atoms in the alloy apply a compressional stress on neighbouring atoms, and smaller atoms apply a tensional stress on their neighbours. This particular composition of alloys helps to resist deformation when a strong force is applied on it. Even when the amounts of each element in an alloy are altered slightly, this presents huge differences in physical engineering properties and behaviour. For instance, very small amounts of carbon (C) (between 0.2% and 2.1%) are added to iron (Fe) and act as hardening agents preventing dislocation of the iron atoms. From the image on the left it is possible to see how the atoms of carbon (A) place in between the atoms of iron (B), preventing the sliding of the layers of iron atoms. However, in case the amount of carbon was excessive, this would have the opposite effect, causing the iron to be brittle and break easily. Some alloys are made by melting and mixing two or more metallic elements. The first alloy ever discovered was bronze, it was made of copper and tin, and was discovered during the prehistoric period known as the bronze age. It was originally used to make tools and weapons, but later it has been used for ornaments, bells, statues, and bearings. Video of crash tests Investigating the effectiveness on crumple zones during a frontal collision SUV Mass of the trolley/kg Distance from the wall /m Time taken/s Distance travelled after collision/m Detailed history of the airbag production Invented at the start of the 1950s, it only came to wide use during the 1960s. Air bag-equipped cars have demonstrated, both in controlled tests and everyday use, their effectiveness and reliability (in frontal collisions, deaths for drivers, were lowered by 28 percent in vehicles featuring air bags). In order to answer to the increased of safety concerns of the consumers, the federal government has forced all car manufacturers to upgrade the safety features installed on their cars. The Department of Transportation (DOT) regulations require that all cars sold in the US, being produced starting from year 1990, had to feature a passive restraint system. Passive restraint systems are security systems that require no activation by the driver and usually are identified to be automatic seat belts and air bags. For air bags, until year 1994 the regulations only require a driver’s air bag and must include passive protection on the passenger’s side (seatbelts). Later, in 1991, a new law required both driver and passenger air bags in all cars by year 1998 and in light trucks and vans by year 1999. Air bags are inflatable cushions designed to protect car passengers from serious or even fatal injury in case of a collision. The air bag is part of a system, also known as an air cushion restraint system (ACRS) or an air bag supplemental restraint system (SRS) (they are called supplemental because the air bag is designed to supplement the protection of seat belts). When detecting a collision, the air bags inflate instantly to provide the passenger with a big gas-filled cushion. A typical air bag system consists of an air bag module (containing an inflator or gas generator and an air bag), crash sensors, a diagnostic monitoring unit, a steering wheel connecting coil, and an indicator lamp. These components are all interconnected by a wiring harness and powered by the vehicle’s battery. Air bag sensors are specifically designed to prevent the air bag from inflating when the car travels over a bump or in case of a minor collision. In a frontal impact equivalent to hitting a solid barrier at a speed of 14.5 Km/h, the sensors located in the front of the car detect the sudden deceleration and send an electrical signal activating an initiator. The initiator is similar to a light bulb and contains a thin wire that heats up, breaking through the propellant chamber. This sudden penetration causes the solid chemical propellant, usually sodium azide, sealed up inside the inflator to undergo a very quick chemical reaction. This controlled reaction produces harmless blasts of the nitrogen gas that inflates the air bag. The resulting nitrogen gas fills the nylon bag in less than one-twenty-fifth (1/25) of a second, opening its plastic cover on the stirring wheel and inflating in front of the passenger before this hits the stirring wheel. As the occupant hits the inflated bag, the nitrogen gas is pushed out through some openings at the back of the bag. The bag remains fully inflated for no longer than one-tenth (1/10) of a second and is almost completely deflated by three-tenths (3/10) of a second after the impact with the passenger. Talcum powder or corn starch is used to line the inside of the air bag and is released from the air bag as it is opened causing the characteristic white cloud. Components of an airbag An air bag is formed by three main parts: the nylon bag, the inflator, and the propellant. The bag is made from a woven nylon fabric and can differ in shape and size depending on the specific vehicle safety requirements. Talcum powder or corn starch is used when handling the air bag, since either of the two substances prevents the woven nylon fabric from sticking together and makes assembling process easier. The inflator body is made from either stamped stainless steel or cast aluminium. Inside the inflator body there is a filter assembly formed by a stainless steel wire mesh with ceramic material held in between. When the inflator body is assembled in the factory, the filter assembly is wrapped by a metal foil to maintain the filter sealed preventing propellant contamination. The propellant, typically sodium azide ,in the form of black pellets, is combined with an oxidizer and is usually located inside the inflator body between the filter assembly and the initiator. Evaluation While analysing how I dealt with the Group Four Project, I noticed some facts that I could have improved, hence improvements that could be done in how my Group Four has worked. The members of my Group Four Project were: Jacopo Mauro, Daniel Gardin, Maria Airchinsky, Edoardo Nalon and Laure Rasscheart. I noticed that when we started to work at the project, we weren’t working as a team, as we still didn’t know what we really had to do, as time passed we got to know each other better and gained more confidence, thus, we started to work more as a team and we managed to assign tasks inside within the group, for example: Edoardo had to contact some car stores and to gather information about the crumple zones and the materials used in the car production, Jacopo and Daniel were the ones who worked on the physics experiment, since they are the two members of the group who have taken the physics course, while Laure, Maria and I did the chemistry experiment, since we had the idea of the inflation of a balloon as a representation of an airbag. The project could have been done in a more efficient way; we lost a lot of time to actually start with various ideas, set the experiments, and start working as a group, although it is possible to recognize the fact that our problems in getting organized were also due the fact that the members of the group never had study periods at the same time. Probably, something that could have really helped our report was to have a â€Å"leader† perhaps not the smartest, but the one who could have made sure that everyone who was actually proceeding with their tasks, and not wait for the last minute to do so. Perhaps he/she could have given the others some deadlines, and set up meetings to see how everyone was doing. Another thing that we could have improved in our Group 4 Project was that we didn’t have many meetings, we had also the summer to work on it, and we didn’t really do much, so we waited for September when we came back from vacations to start again to worry about finishing the project. Moreover, every member of the group was at a different level in chemistry and math, for example: Jacopo and Daniel are very good at chemistry and physics, in fact they chose the scientific course, while Laure, Edoardo, Maria and I don’t even take physics and aren’t objectively very good in chemistry. However, what emerged from our difficulties was a complex and elaborated project, a research on an important thematic such as safety in the streets, focusing on car accidents. Our project could be expanded on an international scale by suggesting other schools to perform the same research as we did, hence rising internationally the awareness in students on how chemistry and physics are important on a daily basis, how these subjects are at the base of our most important healthy issues.

It Is Good to Be Different Essay

Everyone is different, and each of us has its own personality Owned. But it is nice to be different? Be distinguished from the others. What is to be different? Do you feel alone, living in their different world†¦ It is hard to be different. Everyone sees you as an outsider and will not accept in their world. Among them is the fear that something more of them, others see it as something more unworthy and unnecessary. It is hard to be different because its not easily find their soul mates.

Jesus Christ Superstar vs. The essays

Jesus Christ Superstar vs. The essays Jesus Christ Superstar vs. The Passion of The Christ There are a handful of movies made to date, that depicted the controversial subject of Jesus Christ of Nazareth in his final days, the two most successful films that retold this historical tale were written by authors with contrasting religious beliefs. The diverse way that the same storyline is portrayed in these films makes it easy to compare Jesus Christ Superstar and The Passion of the Christ. Jesus Christ Superstar was written more than thirty years ago as a musical. It has a lighthearted 1970s style. Andrew Lloyd Weber was the composer for the project and breathed life and vibrancy into characters through song. Though the story is about a serious matter the play counts on comic relief to ease some tension from the touchy topic. One of the biggest differences in the movie is the fact that Mary, the mother of Jesus, does not appear due to the fact the author was not Catholic. This musical has been on the scene for years and still remains a classic tale of the last days of Christ. The Passion of the Christ was released in February 2004, and was written as a true story, according to the bible, of the last seven days of Jesus of Nazareth. It is such an intense drama that you hardly notice any background music, which is usually a main focus of a movie. This movie is nothing to laugh at. It is an emotional violent, blood-splattered movie that requires a box of tissues to accompany you to see it, and weak stomachs need not attend. Unlike Jesus Christ Superstar, Mary, the mother of Jesus is one of the main characters in this movie due to the Catholic influence of the author. This is a story unlike any other of the last days of Christ. These two movies have the same basic story line, but very different content. The music in Jesus Christ Superstar is phenomenal and has you singing along and although the power of music is overwhelming to the soul it does not com ...

How to write an excellent resignation letter (examples included)

How to write an excellent resignation letter (examples included) I quit. J’arrete. Ich gebe auf. Me rindo. Whatever the language, the sentiment is the same:  I’m outta here. However, as a professional person, you need to express that maturely and firmly- ideally, one that doesn’t alienate anyone at the job you’re leaving. I’m sure we all have that fantasy where we tell off everyone who wronged us on the way out the door, but that person in the fantasy/movie/TV show never seems to have to live with the consequences afterward. Or meet up with said colleagues at an industry event, because the world is awkwardly small. So it’s in your best interest to make sure that your resignation letter is clear, concise, and polite. Here are some best practices you can follow to make your big exit a professional one. Why a Resignation Letter?In these digital times, why should we submit a resignation letter, anyway? A paper trail does seem old-fashioned, but in this case, it’s a best practice. It makes your intenti ons clear, as well as the conditions. You’re removing any ambiguity about the end of your time there.And sure, this could be an email (all of the same principles would apply), but a letter makes things official in every sense. It also gives you a prop to take along to the face-to-face meeting with your boss, when you let him or her know that you’re leaving. A resignation letter can also help your boss and your company start the transition process, get a replacement for you approved, and start planning internally, etc. The paper trail is beneficial all around.So what should go into your letter? Let’s look at some examples of what to do (and perhaps more importantly, what not to do).Necessity #1: A Professional GreetingYour letter should be addressed to your boss. There’s a good chance that this letter will merely end up in a file in HR, but it starts with your boss. Assuming this is someone with whom you work reasonably close with on a daily basis, it does n’t have to be super stiff and formal. Specific and professional is the right tone here.For example:Dear Mary,Mary,Bad examples:Dear Ms. Stone,Hey Mary,To whom it may concern:Dear Human Resources representative,Even if you’re not close with your boss, chances are you have a working, first-name-basis relationship. Maintaining that in your official letter is okay. You don’t need to keep a Victorian level of formality here- just make sure it’s a professional tone.Necessity #2: State Your IntentThe whole theme of your resignation letter is the statement that, well, you resign. You don’t need to play coy- the time has passed for you to fish around for a counteroffer if it’s gotten this far. At this point, you’ve made your decision to leave, and this letter needs to reflect that.For example:I will be leaving my position as Customer Service representative.I resign my position as Customer Service representative.Bad examples:The time has come for me to think about parting ways with this company.All good things must come to an end.I will not be coming in after August 30.You want your intent to be as direct as possible. You are leaving, plain and simple. There’s no need to mention where you’re going. You can discuss that with your boss (though you’re not obligated to do so) and your colleagues if you want, but there’s little purpose for including that in your resignation letter. That’s especially true if you’re moving over to a competitor- you don’t want to create ill will in this letter or cause any drama.Necessity #3: Your End DateThe most crucial detail in a resignation letter is your end date. Legally and according to your company’s policy, you might be required to give a minimum amount of notice (two weeks, or possibly more, depending on the company and the role). If that’s the case, you don’t want there to be any confusion about how much notice you give. If it’s right there in writing in a letter dated two weeks before your last day, you’re saving yourself the hassle. It also starts the clock for your boss and your company, kicking off the transition plan of training, hiring, and otherwise covering your impending departure.For example:My last day in the office will be Tuesday, June 30.I am leaving my position as a Customer Service representative, effective June 30.Bad examples:I will be leaving in a few weeks.I will be leaving the company after a period of time. Here is my required notice in accordance with company policies.The bad examples here are all too vague. With the last one, you’re aligning yourself with company policy, which is good, but it still doesn’t tell the reader how much notice that actually is. Be as specific as possible on the time you have between now and your last day.Necessity #4: A Gracious ToneYour resignation letter is not the time to air grudges, take passive-aggressive sh ots, or otherwise be unpleasant. Regardless of how you feel about your (soon to be former) job or your boss, this letter should be an exercise in professionalism and graciousness. An excellent way to do that is to say a simple â€Å"thank you.† Even if you hated your job, you got something from it at some point. Focus on that positive bit if you need to.On the flip side, if you loved your job, your coworkers, your boss, the cappuccino machine, everything about the place, don’t write page upon page waxing rhapsodic about all that you’re giving up by leaving. A brief, heartfelt compliment to the company, or a thank you, is fine.For example:I’ve appreciated the opportunities I’ve had here.Thank you so much for the opportunity to work and grow as part of the Customer Service team.This company has been a great home for me for the past six years, and I thank you for being a big part of that as my boss and mentor. I’ve learned so much in my time he re, and I know that this company will continue to grow and thrive.Bad examples:I’ve enjoyed SOME of my time here.I think we both know that this has been a terrible place to work, but I appreciate the opportunity.This is a great company, but the management leaves a lot to be desired, so I am leaving.I hope the next person in this position enjoys the challenges of micromanagement and stressful workloads that I have experienced in my time here.You’ll have plenty of time to vent personally about your work grievances as you leave, but really, you stand to gain nothing by putting negativity into your resignation letter. And unless you’re leaving the state and your current industry, you always run the risk of running into the same people later on. So you’re far better off taking the high road and making sure your exit is a classy one.Necessity #5: Your End GameWhen you hand in your resignation letter, it can kick off a bit of chaos- your position will need to be filled, but your duties will also need to be covered until they can replace you. As part of your resignation letter, it’s a good idea to convey what your availability is during that transitional period.For example:Over the next two weeks, I would like to work with you on training or any necessary transition duties as I wrap up my time here at the company. Bad example:I will be available to train a replacement.I plan to be very busy until my last day.These are vague†¦ are you available to train a replacement anytime, even after your last day? Are you saying you’ll be too busy to help prepare someone else or that you’ll be busy helping with the transition? As with everything else in your resignation letter, clear and concise are the way to go.After that, you’re ready to close out your letter and move on. The basic closings are fine here- again, you don’t need to go overly sentimental or formal, but you should also write as if it will be read by anyone at the company.For example:Sincerely,Best wishes,Bad examples:Adios,Bye Felicia,Warmest eternal regards,And with that signing flourish, you’re done! You’ve resigned, and you’re ready for your exciting new job. Let’s recap the good example resignation letter as a whole.Dear Mary,Please accept this letter as notice of my resignation as a Customer Service representative. My last day in the office will be Tuesday, June 30.Working here has been an incredible opportunity, and it was not an easy decision to leave to pursue another opportunity. This company has been a great home for me for the past six years, and I thank you for being a big part of that as my boss and mentor. I’ve learned so much in my time here, and I know that this company will continue to grow and thrive.Ahead of June 30, I would like to work with you on training or any necessary transition duties as I wrap up my time here at the company.Thanks again for the opportunity to be a member of this team!Sincerely,David

Argument Paper on Abusive Families

There is a controversy that children decide whether they should be removed from multiple fighters' strikes at their mother's home and children witness these crimes, but their fathers will not abuse their children. In my opinion, families of domestic violence, whether participating or not, must be removed from their families at once. Parents need to support their children and ensure that the children are safe in a happy, safe and loving environment at home. Household domestic violence and abuse are permanent problems of society. Domestic violence tends to be hidden by emotion, not by being classified as abuse by the victim until it becomes a problem of recurrence. In fact, most of the unreported violence is due to the desire of the victim to protect the criminal. Media often creates news articles and articles on the most sensitive cases of domestic violence. Violence and abuse are one of the most troublesome tasks the family faces today. Abuses may occur between spouses, between paren ts and children, and among other families. Since many cases of spousal abuse and child abuse have not been reported, it is difficult to determine the frequency of domestic violence. In any case, research indicates that abuse (reporting or not) has a major impact on the family and society as a whole. Domestic violence is a major social problem in the United States. It is often said that violence is among families and families, especially spouses. Family sociologists have created the term intimate partner violence (IPV) in order to include unmarried, living together, same-sex couples. Women are the main victims of intimate partner violence. It is estimated that one quarter of women experienced some form of IPV in their lives (compared to one in seven females) (Catalano 2007) Definition of Domestic Violence * Domestic violence is the abuse of power, trust or dependence in the family and risks the survival, safety or happiness of others. This includes a variety of abuses such as spousal abuse, abuses and classes of the elderly, child abuse and school, child abuse, parent abuse, testimony to others in the family. Domestic violence includes some or all of physical abuse, psychological abuse, crime harassment / pursuit, abuse, sexual abuse, economic abuse and spiritual abuse. There are many kinds of domestic violence. Partners, carers or families cause control, domination, or fear of violence, abuse or intimidation. It is not necessarily physical abuse. There are emotional, psychological, economic, sexual, or other kinds of abuse (including animal cruelty against pets, damage to individuals and common property). Children living in connection with abuse acts are considered to be at risk of being harmed by direct or indirect harm by witnessing the abuse of their parents or carers. Children living in families of domestic violence or domestic violence are at higher risk of sexual abuse.

Relationship Between the Characters in Winter Dreams by F. Scott Essay

Relationship Between the Characters in Winter Dreams by F. Scott Fitzgerald - Essay Example Dexter has American dream since he employed his efforts in pursuing the interest of his life. When he met Jones for the first time, he was attracted to her. He did not move, instead he spent a lot of time staring at the beautiful woman. This paper analyzes Dexter relationship with Judy. The relationship between Dexter and Jones seems to be a first sight love relationship (Becnel, 140). When Dexter saw Jones for the first time, he was glued to her. The attraction of Dexter to Jones influenced the choices that Dexter made. He was ready to quit his job because of the beautiful Jones. Dexter told caddy master that he was done with his job. He made this remarks after a strong attraction to Jones. He wanted to spend his life with Jones and would do anything to achieve that ambition. The extent to which he was attracted to Jones shows how true feelings could influence his decisions. Dexter left a low a paying job to seek a means that could help him win the heart of Jones (Fitzgerald 513). D exter’s decision to quit the golf club hanged on the influence of the eleven-year-old Jones who treated him like a junior. Jones undermined Dexter because of the wealth that her family had. The relationship that existed between Dexter and Jones was an intimate relationship. Dexter wanted Jones to be with him. He could not control or hide his feelings towards Jones. It was difficult for Dexter to make any decision that could keep him away from Jones. Dexter had a dream of winning the heart of Jones. He was convinced that wealth could help him win the heart of Jones. On the hand, Jones did not reciprocate Dexter’s love. In intimate relationship, partners need to exercise dialogue. Dialogue held between partners provides a chance for making correction and ironing out relationship differences. Jones did not offer any information that was transparent in their relationship. The relationship between Dexter and Jones portrays a theme of emptiness (Stanley 333). Dexter dream en ded when Devlin gave him news regarding the status of Jones. He took his time to know more about Jones life. Their conversation ends when his American dream of leading his life with Jones ends. The reaction of Dexter indicated the extent of love that he had for Jones. Though Jones had been out of his life for about seven years, he had a deep feeling for her. Life in the story ceases to have meaning because of the shattered dream of Dexter. He does not find any meaning to life since the dream in his entire life is meaningless. Dexter looked at his age and realized that he had spent his life chasing for a dream that could not come true. At the end of Dexter’s discussion with Devlin, Dexter saw the reality in their relationship. He realized that he had banked his hopes where they could not be appreciated. Sometimes a relationship could prove to be sour. When a partner does not reciprocate in a relationship, life in that relationship ceases to have a meaning. Dexter had spent his time acquiring wealth in order to meet the needs of his desired love. He knew that Jones could not accept him without wealth. He ventured into business with an aim of making wealth, which could sustain his life with Jones. Devlin message comes as a shock to the relationship. It shuttered the dream that Dexter had about Jones. It is important to note that Dexter knew that Jones had been married. Ironically, he felt that Jones could still

Saponification Lab Report Example | Topics and Well Written Essays - 500 words

Saponification - Lab Report Example Although soaps and detergents are surfactants they are different in that sops are made from natural products while detergents are made from man-made product which may have some negative effect on the environment. Soaps work through a process called emulsification. This is where soap combines with non water soluble agents detaching them from the material. A micelle can be found in colloidal electrolyte solutions of soaps and detergents. It is formed from an aggregate of molecules resulting in charged particles (Herz 136). Formation of potassium soap is as a result of carboxylate anions and univalent cation to form a soap salt. A mixture of anions is due to the fatty acid residue present in the triglyceride molecule. No precipitate is formed with water because potassium soaps are highly soluble. The experiment was a success as potassium soap which was the required product was achieved at the end of the experiment. The potassium soap was able to remove grease thus proving the efficiency of the product. Hard water contains minerals that easily react with soap to form a solid precipitate called scum, detergents do not react with the minerals in hard water thus the lack of scum while using detergents, this one demerit of using soap over detergent. Soap is cheap and does not damage the fabric compared to detergent. Detergents on the other hand are effective against tough stains compared to soaps (Herz

State Budget Nationally and in Massachusetts Essay

State Budget Nationally and in Massachusetts - Essay Example The budget cuts ratified in no less than 46 states in addition to the District of Columbia ever since 2008, have been executed in all main sections of state services. The state services where the budget cut have been incurred include the health care segment in around 31 states, primary education segment in 34 states as well as the District of Columbia, higher education segment in 43 states, and services to the old as well as disabled in 29 states in addition to the District of Columbia among other areas. The States have made these budget cuts for the reason that revenues earned by the States from income taxes as well as sales taxes, in addition to other revenue resources used to compensate for the above discussed state services decreased owing to the recession. Simultaneously, the requirement for these state services did not reduce and, in reality, the requirement got elevated as the number of people encountering economic complexities amplified (Johnson & Et. Al., â€Å"An Update on State Budget Cuts   At Least 46 States Have Imposed Cuts That Hurt Vulnerable Residents and the Economy†). ... Throughout the period of dot-com bubble, Massachusetts considerably decreased the income tax rates, elevated the individual exemption level, cut the rate of tax on dividends as well as interest revenue into half in addition to endorsing a number of tax cuts for businesses. The state fell short of recognizing that the economic upturn due to the dot-com success would not last for long (Massachusetts Budget and Policy Center, â€Å"Fiscal Fallout: The Great Recession, Policy Choices, & State Budget Cuts, Fiscal Years 2009-2012†). Consequent to these cuts in the tax rates and other alterations, the revenue collections from tax decreased to around 5 percent of the total state earnings by the end of the year 2009. Thus, there was a diminution of about $3 billion in revenue generated from tax. This diminution in the tax revenue produced fiscal instability over the years. Massachusetts had not reinstated funding for necessary state services or made sufficient deposits into the state f und, in order to be equipped to face potential economic depressions. During the recent financial calamity, Massachusetts had depended principally on around $3 billion funds generated in the form of budget cuts and reserves to deal with the continuing budget shortfall. Massachusetts also collected about $1 billion in the form of taxes, and utilized more than $1.5 billion per annum in the form of Recovery Act as well as associated financial support from the federal government in the last couple of years. The federal government funds performed an imperative function in assisting all the states in the US to protect the vital state services and prevent further tax increments

Shock Advertising and High Fashion Brands Essay

Shock Advertising and High Fashion Brands - Essay Example The paper "Shock Advertising and High Fashion Brands" talks about High Fashion Brands and Shock Advertising. Shock advertising, sex and high fashion brands make an irresistible mix. Over half a century of research has proven to be in favor of sex in advertising as Wikipedia (2005) suggested: â€Å"Further evidence comes from Gallup & Robinson, an advertising and marketing research firm which reports that in more than 50 years of testing advertising effectiveness, it has found the use of the erotic to be a significantly above-average technique in communicating with the marketplace, "although one of the more dangerous for the advertiser. Weighted down with taboos and volatile attitudes, sex is a Code Red advertising technique . . . handle with care . . . seller beware; all of which makes it even more intriguing."† Lately the trend has continued with a lot of strength: â€Å"In recent years ads for jeans, perfumes, and many other products have featured provocative images that we re designed to elicit sexual responses from as large a cross section of the population as possible, to shock by their ambivalence, and often to appeal to repressed sexual desires, which are thought to carry a stronger emotional load†.

World War I Research Paper Example | Topics and Well Written Essays - 1000 words

World War I - Research Paper Example One must understand that there were a number of different reasons as to why the World War I broke out in the first place. The formation of the Central and the Allied alliances had a very essential role in lengthening the time period of the war which actually made this war into a very destructive one from a number of different aspects (Higham 2003). Within the Western and the Eastern fronts of Europe, there were clear cut signs of formation of armies and this played a huge role in erupting the war from the aegis if the sea. Essentially the war kicked off from these quarters. The role of the United States was immensely significant in starting the World War I. Similarly it played its decisive role at prolonging the war to great extents as well. There were a number of victories and losses within the World War I. However what is most important is the need to understand that the whole war was a huge loss to the society and the peoples of the different nations (Murphy 1979). Their lives were ended, properties decimates and so on and so forth. The humanity got a real shock from the domains of the leadership regimes working within the countries, who were actively or inactively involved within the war itself. So many of the children lost their parents, a number of them even lost their lives. Women lost their husbands and brothers to thi s war and hence the blow to the whole structure of the family was something that could easily be suggested as a major negative within the crux of the situation that took place during the length of the World War I (Walker 2001). The ending was also on a negative note, much like the whole period of the war. The victors might just have won the war but they were unable to win anything else apart from that. Killing innocent people is never considered a victory for any army or a nation so to speak. The interesting thing about World War I was that there were a number of different wars within the World War I

State Budget Nationally and in Massachusetts Essay

State Budget Nationally and in Massachusetts - Essay Example The budget cuts ratified in no less than 46 states in addition to the District of Columbia ever since 2008, have been executed in all main sections of state services. The state services where the budget cut have been incurred include the health care segment in around 31 states, primary education segment in 34 states as well as the District of Columbia, higher education segment in 43 states, and services to the old as well as disabled in 29 states in addition to the District of Columbia among other areas. The States have made these budget cuts for the reason that revenues earned by the States from income taxes as well as sales taxes, in addition to other revenue resources used to compensate for the above discussed state services decreased owing to the recession. Simultaneously, the requirement for these state services did not reduce and, in reality, the requirement got elevated as the number of people encountering economic complexities amplified (Johnson & Et. Al., â€Å"An Update on State Budget Cuts   At Least 46 States Have Imposed Cuts That Hurt Vulnerable Residents and the Economy†). ... Throughout the period of dot-com bubble, Massachusetts considerably decreased the income tax rates, elevated the individual exemption level, cut the rate of tax on dividends as well as interest revenue into half in addition to endorsing a number of tax cuts for businesses. The state fell short of recognizing that the economic upturn due to the dot-com success would not last for long (Massachusetts Budget and Policy Center, â€Å"Fiscal Fallout: The Great Recession, Policy Choices, & State Budget Cuts, Fiscal Years 2009-2012†). Consequent to these cuts in the tax rates and other alterations, the revenue collections from tax decreased to around 5 percent of the total state earnings by the end of the year 2009. Thus, there was a diminution of about $3 billion in revenue generated from tax. This diminution in the tax revenue produced fiscal instability over the years. Massachusetts had not reinstated funding for necessary state services or made sufficient deposits into the state f und, in order to be equipped to face potential economic depressions. During the recent financial calamity, Massachusetts had depended principally on around $3 billion funds generated in the form of budget cuts and reserves to deal with the continuing budget shortfall. Massachusetts also collected about $1 billion in the form of taxes, and utilized more than $1.5 billion per annum in the form of Recovery Act as well as associated financial support from the federal government in the last couple of years. The federal government funds performed an imperative function in assisting all the states in the US to protect the vital state services and prevent further tax increments

Confessional poetry Essay Example for Free

Confessional poetry Essay Like almost all of Aristotles recommendations in the Poetics, the unity of action is grounded in what a hypothetical viewer is likely to see and, more important, to believe. Tragedys formal coherence, in other words, is itself tested and therefore relies for its ability reliably to produce its defining effects upon its phenomenological consistency with a hypothetically pre-aesthetic concept of human nature. Despite his contention that poetry and politics may employ different standards of correctness, both are ultimately subject to the fundamental structure of center and periphery. In fact, it is the unity of action by which aesthetic representation accesses rituals spellbinding and emotionally charged effects. As Gans writes, Discourse, as it emerged from ritual, was temporalized, as was ritual; its own duration followed the irreversible progress of the rite, which itself followed that of the original event. . . Discourse operates within the temporal limits of the original crisis/resolution, which, whether it last a few hours or a few days, is of necessity extremely short in relation to the normal life span of its participants. . . . The elaboration of ritual is less a prolongation of the critical moment than the addition to it of other episodes. Significance is thus originally a short-term phenomenon, which we may assume to follow more or less the time scheme of a drama, where the speeches of the characters occupy a real time of interaction (Origin of Language 243, 288). Aristotle anticipates Gans in grounding the significance (or, to use his word, beauty) of literary discourse in a ritually derived temporality. As Aristotle writes in Section 7: Beginning is that which does not necessarily follow on something else, but after it something else naturally is or happens; end, the other way round, is that which naturally follows on something else, either necessarily or for the most part, but nothing else after it; and middle that which naturally follows on something else and something else on it (30). To make the connections between aesthetic contemplation and ritual participation too explicit, however, is to risk falling into what Aristotle might have called the Platonic fallacy. Hence his recommendations with respect to the construction of plots tend to de-emphasize the perceptual elements most closely associated with originary representation. The three elements of plot, according to Aristotle, are peripety, recognition, and pathos, which he defines as a destructive or painful act, such as deaths on stage, paroxysms of pain, woundings, and all that sort of thing (37). The emotions aroused by pathos play a paradoxical role in Poetics: while he identifies pity and terror as the tragic emotions, the most effective formal means by which they are aroused are, in Aristotles view, the least connected with poetic art. Though the visual adornment of dramatic persons can have a strong emotional effect, this is the least artistic element among the six constituents of tragedy (29); and while it is possible for the fearful or pathetic effect to come from the actors appearance, the mark and characteristic of a better poet is to engender these effects from the very structure of events (40). Again, originary analysis points to how this, one of the most influential of Aristotles literary opinions, can be understood as an attempt to reconcile what increasingly appeared to be the potentially mutual exclusiveness of aesthetic contemplation and ritual participation. The non-instinctual attention of the periphery toward the central object at the originary scene must be, at least initially, captured and sustained (for however brief a time) through the eyes. That is, peripheral identification with the central figure is first visual and then replayed on each individuals internal, imaginary scene of representation. For this reason, ritual retains a primarily visual orientation. Thus, to define aesthetic excellence as that which resists the strict mimetic conservatism of ritual is to disconnect even more radically art from its violent origins. Similarly, Aristotles recommendation against reliance on the deus ex machina arises not merely from the organicism of his concept of dramatic plot, but from his perception that the proper phenomenal model for tragedy is not ritual but revelation. The poorest plots, he writes, are those that are contrived by the poet, such as that of Iphigenia, where Orestes says what the poet, rather than the plot, wants him to say in the recognition of his sister. By contrast, the most artistic plots are those that develop naturally but unexpectedly. Ritual is the opposite of revelation, writes Gans in Science and Faith (16). Nothing new must occur there; the only evolution the rite undergoes is the gradual draining away of the truth it was its task to preserve. Rites die and are replaced by others, keepers of new revelations. But these revelations themselves never occur within the framework of ritual; their privileged locus is the individual imagination, whose intuitions are tested only after the fact by the community (16-17). Aristotle thus anticipates Gans in identifying some of the ways in which the aesthetic scenes escape from ritual conservatism enables it to become an important locus for the discovery of fundamental human truths. The durability of Aristotles theory therefore results neither from historic accident nor scholarly conspiracy: discovering that an anthropologically-grounded theory of the sign could sidestep Platos fears about art initiating the contagion of conflictive mimesis enables the classical aesthetic eventually to achieve its logical end point: the exploration the scene of representation qua scene. Aristotles achievement comes not, however, from merely denying the validity of Platos intuited connection of representation and crisis. Both thinkers recognize, as Gans has put it, that [t]he institution of art constitutes an intermediary third term between the minimal institution of language and the maximal one of ritual, and that [l]anguage and ritual are each in their own way coercive (Originary Thinking, 122). Poetry, according to Plato, has ties to the more communally coercive (and therefore threatening) institution of ritual; for Aristotle, it is more closely allied with the individually coercive institution of language. It is significant, however, that Aristotles attempt to rid the aesthetic scene of its Platonic threats never fully succeeds; as Gans writes, [t]hroughout history, Platos qualms about the subversive nature of art alternate with the cathartic claims of Aristotle (Originary Thinking 136). Later literary theorists, 7 especially Horace and Longinus, as we will seewhile they followed Aristotles lead in centering their discussions around mimesis, found themselves having to steer between the Scylla of arts violent origins and the Charybdis of the emotional lassitude of a scenic center devoid of its specifically sacred power. Although, as Gans argues, the relative importance of the Platonic and Aristotelian attitudes depends upon the balance of centrality and decentralization within a given society (Originary Thinking 136), the most famous ancient literary critics maintained the belief that the positions were interchangeable by falling into sacred ambivalence: the unwillingness to further Aristotles desacralization of the aesthetic scene. II. Horace Consider, for example, Horaces Ars Poetica. Both in form and content, this treatise on the craft (techne) of poetic composition is predominantly Aristotelian: like that of the Poetics, the argument of Ars Poetica unfolds according to the prescribed succession of poesis, poema, and poeta (Atkins 70). Both works, moreover, identify unity as the essential determinant of literary quality. During the renaissance, in fact, neoclassical critics frequently spoke of the two as if there were no differences between them: concerning the so-called unity of place, writes Pierre Corneille in Of the Three Unities, I can find no rule. For all their concurrences, however, there is an important difference between Aristotle and Horace. Whereas the former makes only one fleetingand rather dismissivereference to the question of poetic inspiration, the latter devotes a considerable number of words to the elucidation of the temperamental qualities that conduce to literary genius. Horaces contribution to classical literary criticism thus consists of neither an elaboration of the theory of representation nor the practice of poetry, but of his subtle, even hesitant reminders of the poets cult of personality. For Aristotle, Sophocles greatness as a poet is demonstrated a posteriori, the result of his having produced the perfect tragedy, Oedipus Rex. Horace, on the other hand, takes what would no doubt have struck Aristotle as a step back toward the Platonic fallacy by reviving both mystery and violence as indispensable elements of poetic craft. In Ion, Plato had offered the characteristically mythicizing statement that all good poets, epic as well as lyric, compose their beautiful poems not by art, but because they are inspired and possessed (Adams 14). Though Horace does not go quite that far in this anti-Aristotelian direction, his very willingness to consider whether a praiseworthy poem be the creation of nature or of art (Adams 74) indexes his dissatisfaction with what Gans has called Aristotles patently demystifying gesture of identifying the human with the central (Originary Thinking, 135). Though Horace refuses to commit himself explicitly to either side of the craft/inspiration controversyFor my part I do not see what study can do without a rich vein of native gift, nor what the native gift can do without culture (74)other elements of the essay indicate that he may have felt inspiration to be more important than he is willing to admit. First, he repeatedly invokes the Muses, indicating that for him poetic composition was still to be undertaken in an attitude of religious seriousness. Second, and even more significant, is 8 Horaces deliberate and detailed attention near the end of the letter to the social influence and temperamental characteristics of the poet. While men were yet savage, writes Horace, Orpheus, the sacred, the mouthpiece of the gods, awed them from bloodshed and the foulness of their living; whence the legend said that he tamed tigers and ravening lions.

A Study Of Lewins Model Management Essay

A Study Of Lewins Model Management Essay In the refreezing stage the company stabilized changes by establishing systems that can establish behavioural pattern in the organisation. A new performance appraisal system based on behaviour and results was introduced to encourage customer service. (Goodstein., D., L. Burke, W., W., 1991) 14 It is not easy for an organisation change its structure and business processes since any change may lead to some level of resistance by the employees. One of the main causes for resistance is the fear of the unknown and loss of what is familiar. There are four reasons of resistance from employee to organisational change including 1) Parochial self-interest, 2) Misunderstanding and lack of trust, 3) Contradictory assessments, and 4) Low tolerance for change. (Buchanan D. Huczynski A., 2004) BA tried to change behaviour by changing the management style from authoritative to participative. BA wished employees participate more in management decision but since this was unfamiliar employers would fall back to the old patterns. 15 A tactic that was used in BA to manage resistance to change was the HR policy which included training guidelines. Such an HR policy is important in making the employees understand and react positively to change. There is also an example where resistance to change hindered the organisations goals and objectives. In an attempt to cut down cost can compete with low cost airlines BA tried implementing a new payment system and also hiring workers for lower salaries. This created insecurity among the employees which ended in a strike that cost the company in millions in 2000. Therefore handling resistance and the HR aspects of the company is vital to a successful change process. 15 REFERENCES 16 Wilson, C.D., (1992), A Strategy of Change, Thomas Learning, London 16 British Airways, 2006, Leaders For Business: What are we looking for?, http://www.britishairwaysjobs.com/baweb1/?newms=info196 (22 December 2006) British Airways, 2006, Our Recruitment Process: The Assessment Process, http://www.britishairwaysjobs.com/baweb1/?newms=info48 (22 December 2006) 16 Paton, R.A.

The airline operates in geographical areas such as the UK, Europe, America, Africa, Middle and Far East, Australasia and Indian sub-continent. For the year ended March 2009, the company generated revenues of  £ 8,992 million which is an increase of 3.1% on the  £ 8,753 million revenues generated in the year ended 2008. The net loss of the company was  £358 million during the 2009 financial year, showing a major decrease from the  £696 million profit in the previous year. British Airways Plc was formed from the airlines,  BOAC,  BEA, Cambrian Airways  and Northeast Airlines on 1 September 1974 through  nationalisation  by the Labour Government. In February 1987, thirteen years later, the company was privatised. Measured by passenger numbers, British Airways was the largest airline of the UK until 2008. British Airways is listed on the  LSE  and is a constituent of the  FTSE 100 Index. The airline celebrated its 35th anniversary on 31 March 2009. Change management According to cook et al (2004) change management is a set of processes that is employed to ensure that significant changes are implemented in an orderly, controlled and systematic fashion to effect organizational change. One of the goals of change management is to reduce resistance to change in order for organizational members accept the change and thereby achieve the organizations goal of a smooth transformation. Change management can be seen to have five specific stages that must be realized for an organisation to be successfully implementing change. Firstly the organisation must know why a specific change or series should be brought about. Secondly the organisation must be motivated and desire to go through this particular change. Thirdly the organisation must posses the knowledge of how to carry out the change. Fourthly the organisation must acquire new skills and behaviours that are necessary for the change to occur. Lastly the organisation must become sustainable by making these new behaviours their usual practice. Further according to Wilson (1992) change can occur mainly in two dimensions depending on the theories and models used. This view explains that change can be either planned or unplanned. Also change can be described in terms of the process or implementation strategy. The issues of understanding and managing change within an organisation depend on the change approach that is selected by the organisation. Organisational Structure British Airways operates as a group of companies whose main industry sectors are international and domestic scheduled and charter air services carrying passengers, freight and mail as well as providing supplementary services. The group consists of British Airways Plc and a number of subsidiary companies, including British Airways Holidays Ltd, British Airways Travel Shops Ltd etc. The two main operating bases of the company are Heathrow and Gatwick airports and has established in branches around the world. The company is listed in several stock exchanges including LSE, Munich, US etc. British airways together with its partnerships have managed to extend its network thus entering all significant markets. As for the structure of BA, it has suffered a shift from modern to post modern to post modern organisational structure i.e. it has moved from mechanistic to more organic style of operation. The operations of BA can be analysed departmentally into Planning, Distribution and mileage partnerships, Marketing communications, Global contact centres, eCommerce, Triton Programme, Revenue management, AirMiles Travel Company, Travel Shops, BA Holidays, BA travel Clinics, Corporate communications, BA world Cargo, Ground Operations, BA engineering, Information management, BA shares etc. Each division has its own functionalities to perform, goals and objectives to meet which contributes to corporate aims and objectives. Department Responsibility Planning Planning fleet, network, schedule, infrastructure, resources, property Distribution mileage partnerships Ensure that customers can book pay and ticket a booking through the website, contact centres, shops, travel agents around the world Marketing communications Marketing communications, advertising, promotions, gain insight into customer needs Global contact centres Delivers services to customers who prefer using the phone eCommerce Major projects to broaden the range of transactions customers can do on their own, improve quality of online channels Triton Programme The 10 year contract with Amadeus, leading provider of travel industry systems Revenue management Monitors, controls, forecasts sales working to improve profitability AirMiles Travel Company Carries out customer loyalty programmes Travel Shops Provides personal services and expert advise from well travelled consultants BA Holidays Sells holiday packages travel Clinics Offers travel health advice and comprehensive vaccination service Corporate communications Protects and manages the global reputation ensuring that a wide audience are aware of the airlines news and developments. world Cargo Provides freight, mail and courier services Ground Operations Management of Customer services and terminal operations with safety and security Engineering Responsible for aviation maintenance providing full support for the fleets Information Management Responsible for all IT across the BA group and plays a fundamental role in shaping the future of the airline BA shares Responsible for all investor relations Table 1: Departmental Analysis of British Airways Market Environment PEST Analysis The Airline industry has become extremely competitive due to the budget airline and the current unfavourable economic conditions. All player compete for the market share in an environment where the bargaining powers of customer have increased and there is no control over the powers of fuel suppliers and prices. In the current economic conditions there is limited growth in volume and demand for air travel has declined significantly. The PEST analysis shows the external factors that affect the organisation and its change processes. It also reveals the changes the organisation must make in order to remain competitive in adverse market conditions. Thus, this section looks into the external environment of British Airways since change strategies are affected by the factors and changes in the macro environment. Such changes could bring about favourable or adverse effects on the companys turnover and growth. The PESTEL framework has been applied to examine the external factors and its impact on the company. Political and Legal Factors Developments in the political and legal factors can have a high impact on the airline industry. Political developments include changes in governmental policies, international regulations and legislations, government taxes on air travel, political and economical relationships with counties, changes in airport and aviation rules etc. Some of the developments have a favourable impact on the company while some others will have an unfavourable impact. The EU policy has increased air travel and therefore has been a positive impact on the airline industry. On the other hand, increase of government taxes has adverse results on the industry since demand for air travel declines due to high airfare. Economical Factors Economic developments such as increase in fuel prices, unfavourable currency and interest rates, recession, inflation, increase in unemployment has a negative impact on British Airways. In such environments leisure travel declines because people have less disposable income and business travel declines because corporate spending is reduced. Also recession negatively impacts on growth of companies in terms of expansions and buying additional aircrafts. On the other hand, changes such as economic boom, deflation could favourably contribute towards a companys performance. Social and Environmental Factors Airline industry is constantly under pressure for various environmental pressure groups due to high CO emission, noise and the effects on the climate. Also outbreaks of diseases such as such as Swine Flu can decrease air travel. Another aspect that could reduce air travel is safety related issues such as acts of terrorists and crashes. Technological Factors Changes in technology have shown negative and positive impacts on the airline industry. The positive impacts have been safety, cost reduction and ease of booking and planning travel online. On the other hand due to new technological developments such as advanced meeting facilities business travel is not necessary to the same extent as before. BA and Ryanair British Airways aims to operate a high quality service to its customers at a affordable price. It operates long and short haul flights to many destinations around the world and ensures comfort while taking the passengers closer to their destination. British airways mainly operate in three areas, namely passenger transport, cargo and mail services. British airways aim to understand its customers needs and operate accordingly. The company has a strong brand image and the employees are expected to work up to its standards. The organisational structure can be regarded as a flat type because it has only one level of hierarchy that separates Managing Directors at the top from bottom-line employees. On the other hand Ryanair operates on a no- frill strategy which means that the passengers are not provided with any extra facilities and operates simply as a point to point transportation service. It has grown largely in Europe by attracting customers who prefer low ticket prices thereby reducing the market share of British Airways. It mainly operates short haul flights to destinations which are secondary airports. Factors Affecting Change Management According to Paton and McCalman (2008) Change management can be defined as a planned process for changing a core function or organization of an enterprise. Change Management is an organized, systematic application of the knowledge, tools, and resources of change that provides organizations with a key process to achieve their business strategy. (Lamarsh 2000). With the aid of technology the industries and products are congregating which means each firm has to take a very holistic approach to the marketing of goods and services. Paton McCalman (2000). Factors driving change Most organisations change when internal and external environments change. The factors that initiate the need for organisational change can be two fold. The first factor can be called an External Trigger which involves the activities and innovations of competitors, change in customer requirements, legislation and government policies, and so on. Economic change can create the need for change. Also, due to the EU policies many companies had to change their practices and procedures. Environmental pressure groups that impose pressure due to adverse environmental effects can force a company such as BA to change its processes to make it climate friendly. The second factor can be called the Internal Triggers including new product and service design, innovations, appointments of new directors, new ideas on how to achieve service quality etc (Buchanan D. Huczynski A., 2004). The British Airways privatization program that changed the companys ownership was launched due to the impact from such triggers. The aims and objectives of this programme was to improve the organisations performance and gain a competitive advantage over its competitors. According to the change model described by Lewin, organisational change occurs in three stages. The first stage is called Unfreezing which reduces the forces which maintain behaviour as it is currently and recognition of the need for change occurs. The second stage is called Movement which is the development of new practices and the implementation of the change. The final stage is named as Refreezing which is stabilizing the changes that occurred and reinforcement through supporting mechanisms. (Mul lins, J., L., 1999) Involving People It is essential that the organisation manages its human resources in a manner that is favourable to the change process. It is important that the employees understand and support the change in order to have a smooth transformation. If the change managers can make the people involved to see the common objectives and mutual benefits that the change will bring about it helps in making the change more successful (Paton McCalum, 2000). However, each individual will react to change in a different manner. The factors that affect how individuals will react to change are manifold, namely the organisational culture, the reasons for change, factors of change, leadership aspects and organisational structure. The change management style and approach are important aspects with regards to involving the employees of the organisation. Change management requires a considerable amount of skill and previous experience on the management of the organisation. It is important to consider each individuals pe rception and attitude towards the process for it to be a success. For example during the second stage of change, BA developed tactics and programs to bring the vision of the top management-level to the bottom-line employees throughout the organisation. Thus the internal structure and systems were changed and also a permanent training center was established to promote staff training. Stakeholders It is important that the company analyses its stakeholders since the change will have an effect on them. Communication is vital to involve all stakeholders in the process so that the change is successful. It is also important to categorise your stakeholders according to their power and interest involving the change. There are some aspects regarding stakeholders and the change process that should be taken into consideration. Differentiating and grouping employees and deciding how to deal with different types, planning communication in both directions and also looking after the interests off all individuals. There are mainly four types of stakeholders, blockers, sponsors, champions and sleepers Green (2007). Blocker have high power but low level of commitment, while the sponsors have high power and high commitment. Also Champions have high energy and high commitment while sleppers have both low power and low commitment to change. For a successful change it is important to identify the stakeholders with high power and commitment. British Airways has a number of stakeholders who have various interests in the business and from whom the company expects different things. There have been conflicts between these stakeholders due to their differing interests as well as formations of coalitions. It can be observed that most stakeholders have an interest in the organisation performing well. In the above context it is important that the stakeholders are analysed according to the power and commitment grid so that change can be successful. Planning the change The change process must be planned and it is advisable to use models of change and also consider the impacts of resistance to change. Two different change models are discussed in the following section, namely the Mckinsey 7-S model and Lewins Model. The basic principle of the model is that there are seven internal aspects of an organization that need to be aligned if it is to be successful. The 7S model can be used in a wide variety of situations such as improving the performance of the company. The McKinsey 7S model contains seven interdependent factors which are categorised as hard or soft elements. Hard elements are strategy, structure, systems and soft elements are shared values, skills, style and staff. The Hard elements are easier to identify and influence while the soft elements are more difficult to manage but equally important for a successful transformation. The model depicts the interdependencies of these elements in terms of how a change in one element affects the others. According to the model the seven elements must be aligned. In the case of BA, the model can be used to identify what needs to be realigned to improve performance during other changes in the company. What ever the change is this model can be used to understand the interrelationships. Further it can be used to analyse the current position, proposed position and identify the gaps between the two. It is also necessary to adjust these elements to make sure the company works effectively. Now lets examine Lewins change model. According to Lewin, there are three stages of change in an organisation which are unfreezing, movement, and refreezing. Unfreezing Stage accordingly, the first step for BA is to unfreeze present pattern of behaviour to manage resistance. In this stage change did make an impact on individual level due to the implementation of Downsizing of Workforce policy to restructure the organisation. This policy reduced hierarchy, and allowed worked to be carried out easily thus improving performance. (Shibata., K., 1993) The downsizing was achieved through compassion. BA also introduced training programs such as Putting People First to help line managers and workers understand the change and the requirements of the industry. Movement Stage The second stage of Lewins Model is movement. During this stage BA used tactics and programs to bring the vision of the top management and line employees. In support a number of new systems where implemented. (Goodstein., D., L. Burke, W., W., 1991) Refreezing Stage In the refreezing stage the company stabilized changes by establishing systems that can establish behavioural pattern in the organisation. A new performance appraisal system based on behaviour and results was introduced to encourage customer service. (Goodstein., D., L. Burke, W., W., 1991) Resistance to change It is not easy for an organisation change its structure and business processes since any change may lead to some level of resistance by the employees. One of the main causes for resistance is the fear of the unknown and loss of what is familiar. There are four reasons of resistance from employee to organisational change including 1) Parochial self-interest, 2) Misunderstanding and lack of trust, 3) Contradictory assessments, and 4) Low tolerance for change. (Buchanan D. Huczynski A., 2004) BA tried to change behaviour by changing the management style from authoritative to participative. BA wished employees participate more in management decision but since this was unfamiliar employers would fall back to the old patterns. A tactic that was used in BA to manage resistance to change was the HR policy which included training guidelines. Such an HR policy is important in making the employees understand and react positively to change. There is also an example where resistance to change hindered the organisations goals and objectives. In an attempt to cut down cost can compete with low cost airlines BA tried implementing a new payment system and also hiring workers for lower salaries. This created insecurity among the employees which ended in a strike that cost the company in millions in 2000. Therefore handling resistance and the HR aspects of the company is vital to a successful change process.
