Equal Opportunity in the Army - 2746 Words

Tech Communication Robert Snyder Research Paper Equal Opportunity in the Army Propelled by the civil rights movement of the 1960s and to counteract a national policy of segregation and inequality, the Department of Defense (DoD) mandated race relations training in 1971. The violent and nonviolent disorders of the late 1960s were the catalyst that convinced military leaders that race relations education must be provided to every member of the Armed Forces. An inter-service task force examined the causes and possible cures of these racial disorders within the military. The task force, chaired by Air Force Major General Lucius Theus, resulted in Department of Defense Directive 1322.11. This directive established the†¦show more content†¦The situation in today s Army is clearly much different from what existed years ago. Many changes have occurred, moving the Army s EO program from a strictly educational and training initiative to a multifaceted management program with clear goals and objectives.

The concept of the EO program is to formulate, direct, and sustain a comprehensive effort to maximize human potential. It strives to ensure fair treatment of all soldiers is based solely on merit, fitness, capability, and potential in support of readiness. EO philosophy is based on fairness, justice, and equity. It places the responsibility for sustaining a positive EO climate within a unit on its commander.

Women in Sons and Lovers Free Essays

Sons and Lovers, published in 1913, is D. H. Lawrence’s third novel. We will write a custom essay sample on Women in Sons and Lovers or any similar topic only for you Order Now It was his first successful novel and arguably his most popular. Many of the details of the novel’s plot are based on Lawrence’s own life and, unlike his subsequent novels, this one is relatively straightforward in its descriptions and action. D. H. Lawrence has been always criticized for the content of his novel and his characters. Sons and Lovers is another novel which was even banned for years because of its explicit indications to sexual intercourse and the complex and complicated relationship of mother and sons. Society has a certain code fixed for a mother but Lawrence attempted to portray the mother figure in a quite different way. In fact, Lawrence puts question that to what extent a mother should care for her children and shows what happens if a mother becomes wife-submissive through the character of Gertrude Morel who is also known as Mrs. Morel. This paper would attempt to explore the character of Mrs. Morel through the feminist point of view. Before discussing Mrs. Morel’s character through the magnifying glass of feminism, it is needed to focus what does feminism means and what does the feminist criticism deal with. The most straightforward definition of feminism says that is a movement for social, cultural, political and economic equality of men and women. It is a campaign against gender inequalities and it strives for equal rights for women. Feminism can be also defined as the right to enough information available to every single woman so that she can make a choice to live a life which is not discriminatory and which works within the principles of social, cultural, political and economic equality and independence. It is in fact a global struggle for gender equality and end of gender based discriminatory practices against women. Feminism is also related to men in the sense that all gender based equality is in fact a balance between the male and female with the intention of liberating the individual. In that sense the definition of feminism also includes all movements and campaigns that target men and boys for gender sensitization with a goal to end gender based discriminatory practices and achieve gender based equality. Feminist literary criticism is the critical analysis of literary works ased on the feminist perspective. In particular, feminist literary critics tend to reject the patriarchal norms of literature that privileges masculine ways of thinking/points of view and marginalizes women politically, economically and psychologically. Some critics find that feminist criticism makes space for and listens to women’s voices previously muted or drowned out by dominant patriarchal literar y-critical practices. In other words, what the text leaves out says much about the writer, literature in general, and society as a whole. By using this â€Å"hermeneutics of suspicion† literary critics hope to reveal how women are marginalized in the language of literature. Now, in Sons and Lovers, Mrs. Morel is portrayed as the victim of the patriarchal society and the stones in Paul’s life road to success, to some extent. This paper would try to avoid the normal literary criticism to Sons and Lovers, and rather would focus on the analysis of the three tragic women through feminine position, and specially would explore how Lawrence has portrayed Mrs. Morel with all the issues of female essence (differance). Mrs. Morel, who came from a little capitalist class, aloof and cultured, is a woman of knowledge of a Victorian woman but her character can be read from Marxist-Feminist point of view. From very young, she has been struggling against patriarch, fighting for her existence and for women’s rights, longing to become an authoritative, independent and responsible man. As the England industrial atmosphere came, in the man-centered family, her husband treated her sadistically, Mrs. Morel naturally constitute an alliance with her sons to live, she taught them to change their social position and entered the middleclass, through knowledge and will, the children became Mrs. Morel’s tools to make her dream and ambition come true. But all these just paint deep tragic color to Mrs. Morel. Because Mrs. Morel chose the rood to setting up a union with her son to become hermaphrodite didn’t come true. She put her children in her bosom, cast her own dream and life outlook on her children, hoped to fill in her emotion empty because she is a wife-submissive. Although this abnormal maternal lieu helped her sons become outstanding, hold back free growth of individuality, cause their thought variant and their personality split. Mrs. Morel’s existence is the only support to Paul’s life road to become an artist. Through loving his mother, Paul tried to find man’s rights even in sleep. She should be responsible for this abnormal love, no matter what position she held in her sons’ growth, she got only the colored utilizable repay, she didn’t fulfill her emotion’s need, and this is her very most tragic thing. But this is just a simple summary of the whole novel and there are more left for discussion. D. H. Lawrence believed in male supremacy and that is why he wrote that â€Å"as a matter of fact unless a woman is held by man, safe within the bounds of belief, she becomes inevitably a destructive force†. Simone de Beauvoir terms this attitude â€Å"bourgeois conception† and states that Lawrence rediscovers this conception that woman should subordinate her existence to that of man. Thus, Lawrence can be regarded as an anti-feminist. An anti-feminist writing is not only satirical in tone but it represents women nature intended to conform her to male expectations and tries to decide what she ought to be and what is not her own. Mrs. Morel is presented by Lawrence as a proud woman as she came from an old burgher family and that made her pay higher rent to the landlord which is a way of showing off superiority over other miners’ families. Lawrence defines it as â€Å"a kind of aristocracy†. Mrs. Morel did not take Walter’s earnings into account while they got married but after the marriage it became a huge issue for her. She could not accept it that her husband was not a gentleman rather he is a miner and ultimately, this became the reason of failure of their marriage life. Though she married Walter knowingly that he earns a little but after a certain period of time, she started hating her husband for being a miner and for not having a respected job. In the first half, Mrs. Morel is shown with sympathy to be the victim of a brutal husband and of an economic system that oppresses her. Later she becomes the over-possessive mother shifting her growing children and thwarting their natural development towards the independence of adulthood. It can be said that Mrs. Morel became too much authoritative because of her ‘penis envy’. She knew that though she came from a burgher family, still she is bound to obey Mr. Morel as he is the head of the family according to the patriarchal society. Apart from the issue of penis envy, Lawrence presented the relationship between man and series of female stereotypes. The mother’s disappointment with the father leads to the transfer of her deepest feelings from him to her offspring and particularly, the male offspring, whom, unconsciously she begins to treat as substitutes for her husband. The mother who has poured her love into her son instead of giving it to her husband does seem, in Lawrence’s own cherished meaning of the phrase, ‘wife-submissive’. But at the same time, that phrase is a give-away. It sounds an old familiar note. Here is the mother being wife-submissive to her son, says the exasperated voice of Lawrence, when she ought to be preciously that to her husband – a simple case of misdirected energy. It has not been simply misdirected, but distorted as well. The woman does not feel now, for the first time, as a true wife might feel, nor does the son find her love quite so wonderful as all that. Sexual frustration inevitably follows, and this is excellently diagnosed in Sons and Lovers. His mother is far closer to him; she clings to him jealously, fighting against the younger woman’s power, and succeeding in holding the pair apart. Paul wants to marry Miriam but Mrs. Morel resists because she wants Paul â€Å"to marry a lady†. Apart from Paul, she also does the same thing for William. She wants William to be a gentleman unlike his father. Her possessiveness becomes clearer when a girl comes to meet William and Mrs. Morel replies â€Å"I don’t approve of the girls my son meets at dances. † In this novel, D. H. Lawrence has portrayed women, Specially Mrs. Morel with all he weaknesses (female essence) like nagging, orienting the children against their father, making the sons as husband-substitute, showy in nature and being over-possessive. Paul partly disassociated himself from the crude gender distinction he is voicing, although he still endorses the idea that women are by nature unfitted to full-time work. So, Lawrence reveals Paul’s opinion of women’s inferior capacity for work. After all these discussions, it seems quite clear that Mrs. Morel is the victim of one man and therefore can only live out her life vicariously through the progress made by her sons. Miriam also feels victimized by the men in her family and looks to Paul to help her escape from her servitude. Same thing goes for Clara. All of them, especially Mrs. Morel, are defined by men as their â€Å"Other† and thus, marginalized textually as well as socially and sexually. How to cite Women in Sons and Lovers, Essay examples

Labor In America Essays - Trade Union, Factory System, Strike Action

Labor in America The Industrial Revolution was dawning in the United States. At Lowell, Massachusetts, the construction of a big cotton mill began in 1821. It was the first of several that would be built there in the next 10 years. The machinery to spin and weave cotton into cloth would be driven by water power. All that the factory owners needed was a dependable supply of labor to tend the machines. As most jobs in cotton factories required neither great strength nor special skills, the owners thought women could do the work as well as or better than men. In addition, they were more compliant. The New England region was home to many young, single farm girls who might be recruited. But would stern New England farmers allow their daughters to work in factories? The great majority of them would not. They believed that sooner or later factory workers would be exploited and would sink into hopeless poverty. Economic "laws" would force them to work harder and harder for less and less pay. THE LOWELL EXPERIMENT How, then, were the factory owners able to recruit farm girls as laborers? They did it by building decent houses in which the girls could live. These houses were supervised by older women who made sure that the girls lived by strict moral standards. The girls were encouraged to go to church, to read, to write and to attend lectures. They saved part of their earnings to help their families at home or to use when they got married. The young factory workers did not earn high wages; the average pay was about $3.50 a week. But in those times, a half-dozen eggs cost five cents and a whole chicken cost 15 cents. The hours worked in the factories were long. Generally, the girls worked 11 to 13 hours a day, six days a week. But most people in the 1830s worked from dawn until dusk, and farm girls were used to getting up early and working until bedtime at nine o'clock. The factory owners at Lowell believed that machines would bring progress as well as profit. Workers and capitalists would both benefit from the wealth created by mass production. For a while, the factory system at Lowell worked very well. The population of the town grew from 200 in 1820 to 30,000 in 1845. But conditions in Lowell's factories had already started to change. Faced with growing competition, factory owners began to decrease wages in order to lower the cost--and the price--of finished products. They increased the number of machines that each girl had to operate. In addition, they began to overcrowd the houses in which the girls lived. Sometimes eight girls had to share one room. In 1836, 1,500 factory girls went on strike to protest wage cuts. (The girls called their action a "turn out.") But it was useless. Desperately poor immigrants were beginning to arrive in the United States from Europe. To earn a living, they were willing to accept low wages and poor working conditions. Before long, immigrant women replaced the "Yankee" (American) farm girls. To many people, it was apparent that justice for wage earners would not come easily. Labor in America faced a long, uphill struggle to win fair treatment. In that struggle, more and more workers would turn to labor unions to help their cause. They would endure violence, cruelty and bitter defeats. But eventually they would achieve a standard of living unknown to workers at any other time in history. GROWTH OF THE FACTORY In colonial America, most manufacturing was done by hand in the home. Some was done in workshops attached to the home. As towns grew into cities, the demand for manufactured goods increased. Some workshop owners began hiring helpers to increase production. Relations between the employer and helper were generally harmonious. They worked side by side, had the same interests and held similar political views. The factory system that began around 1800 brought great changes. The employer no longer worked beside his employees. He became an executive and a merchant who rarely saw his workers. He was concerned less with their welfare than with the cost of their labor. Many workers were angry

The Wolof People of Senegal essays

The Wolof People of Senegal essays The Wolof people are located on the Coast of Senegal. Their native language is Wolof and their population is approximately 2.5 million. The Wolof people have been around since the 12th or 13th century. After the defeat of the Empire of Ghana around the 11th century, the Wolof people migrated to the coast from Mali. The history of the Wolof has been saved through the griots who recited oral praise songs. The religion of the Wolof is predominately Muslim. This includes praying to Allah five times a day, volunteering and giving gifts to the needy, observance of Ramadan, and a trip to Mecca. Other beliefs of Wolof are that there are good and evil spirits. They believe that the evil spirits live in bushes and tall trees in the middle of the village and that amulets are capable of protecting them from the spirits. Historically, Wolof were ruled by several powerful men who were from high ranking lineages based on the length of time that they resided in the area. The high ranking people elected a supreme leader. Local chiefs were appointed by the leader and paid their allegiance to him by maintaining order in the hinterlands and collecting taxes and tributes. The Wolof can be divided into three classes: the freeborn, those born into slavery, and the artisans. Many people settled in cities working as merchants, teachers, or government officials. However most of them still live in rural areas and work as peasant farmers. A typical Wolof village consists of several hundred people living in family compounds that are grouped around a central village square. The compounds contain houses made of mud or reed. It consists of a compound head, his wives, and their children. Other relatives including aunts, uncles and cousins reside there as well as temporary field hands. The freeborn are the royal lineages and great warrior families. They are the top level of society. These noble families usually engaged in wars to protect and...

Wal-Mart Case Essay Example | Topics and Well Written Essays - 250 words

Wal-Mart Case - Essay Example China benefits heavily from this since almost all consumer goods sold at Wal-Mart stores are made in China. This increases employment in China. However, government deregulation of the retail industry has led to increased retail giants that charge lower prices just like Wal-Mart. This implies that its cost leadership assertion is neutralized. China is a booming economy with a high potential courtesy of its high population. Wal-Mart can utilize the advantages by easing its struggle for cost leadership and adopt a more diverse mechanism of boosting its market. This can be done by cultivating good will from the community in which it operates by fair remuneration of workers and better working conditions in stores and also by its suppliers. This would boost its image thus increasing sales. Wal-Mart uses a number of strategies to maintain low prices. First, Wal-Mart contracts suppliers from China who provides relatively cheap products.

Management Communication- Change Management Report - Assignment Example ement implementation; and the final step involves any corrective action, which needs to be taken to remove gaps in the process (Lattuch and Young, 2011). The purpose of this project is to discuss ways in which changes in the management of a company can be effectively communicated to the employees. In this case, the company is about to make some changes in the senior level management and some staff will also be added to the organization. These thoughts of change are creating disruptions in workplace conditions as some of the workers fear that this change may affect them adversely. As a result, the workers are losing their confidence in the organization and productivity of the company might be hampered. In this context, the change management planning process, organizational activities as well as communication and implementation tactics are to be discussed. Firstly, there are certain positive changes that the company wants to incorporate. This is only possible if the existing structure of senior management is altered as analysts of the company strongly believe that this will be essential in realizing the new goals. Secondly, organizational development (OD) is expected to be achieved through a humanistic approach by relying on human potential. This is the reason why the company wants to add new human resource to its existing base. Organizational development implies the change, which an organization goes through in order to survive and thrive. Change management for organizational development is the way in which decision makers manage changes that are necessary for facilitating organizational development. The first step of achieving organizational development is to create a well-structured plan for the task. Bullock and Batten (1985) has come up with a four phased model of planned change, which can be broken up into exploration, planning, action and integration. The model includes two broad steps, namely the process of change (describing the way in which an

Research Paper - Assignment Example America, unlike other powers before it, was declining in both power and influence at a fast rate. It therefore needed an event that could restore it back to its former glory as the strongest in the world. Contrary to the popular belief that the war was about oil, the gulf intrusion was not. The Gulf catered to only five percent of America’s oil needs. Therefore, losing five percent of oil in the process of gaining super power status was not be an issue for America. 2.

Engine Cooling And Lubrication System

Engine Cooling And Lubrication System Cooling System: Despite the vast improvement in the basic internal combustion engines, around 70% of the energy from the gasoline is converted to heat. As it is not dissipated to the atmosphere on its own, a cooling system is employed for this purpose. Several purposes of the cooling system which it serves by cooling the engine include cooling the engine to keep it from overheating by transferring the heat to the air. This helps avoid the excessive wear and tear at high temperatures, auto-ignition due to hot cylinder which may result in knocking and hence, piston/cylinder failure. It may also incorporate thermal stresses which is not good for the engine itself. Figure . Cooling system and plumbing connection While it serves the purpose of cooling the engine, it also helps the engine to warm up quickly during cold start ups and then maintaining a constant temperature. When the engine is cold, components wear out faster too and the engine is less efficient, emitting more pollution. Types of Cooling System: There are two types of cooling systems found in cars: Air-cooled Liquid-Cooled Air-Cooled Engines: Many small and the medium-sized engines are air-cooled. This category includes most small engines like lawn mowers, chain saws, model airplanes etc. Using the air-cooled system allows both the weight and price of the engine to be kept low, along with reduced complexity of the machine. The air-cooled system is still widely used on most of the motorcycles in use these days. This system utilizes the concept of heat transfer through fins to cool the engine. The cross-sectional area of the fin being larger closer to the head and a reduction in the area as we move further from the engine block. The basic principle on which the air-cooled engines rely on is the flow of air across their external surfaces to remove the excess heat to keep the engine from overheating. The airflow on machines like motorcycles and aircrafts is provided across the surface when the vehicle moves forward. Deflectors and ductwork is incorporated to direct the airflow to the critical locations where more cooling is required. The outer surface of the engine is made from a good conductor of heat and the surface is finned to promote maximum heat transfer, along with which an extra fan is used to increase the air-flow rate; whereas others use the concept of free-convection. These fins are to be properly designed for appropriate cooling effect which is required. Some automobile engines also use exposed flywheels with air-deflectors fastened to the surface. When the engine is in operation, these deflectors create air motion which increases the heat transfer on the finned surface. Even after considering and applying all the measures, the uniform cooling of cylinders is still difficult to achieve on air-cooled engines as compared to the liquid-cooled engines. The figure below shows that the cooling needs are not the same at all the locations. Figure . Variation of heat losses from the fins of an air-cooled aircraft engine. Seventy-one percent of the heat losses occur on the hotter side of the cylinder, containing the exhaust valve. The engine shown was used on a number of different aircrafts. Hotter areas, such as the ones around the exhaust valve and manifold need greater cooling and hence larger finned surface area. Cooling the front of an air-cooled engine which faces the forward motion of the vehicle is much easier and efficient as compared to the back surface of the engine. This may result in temperature differences and thermal expansion problems. Disadvantages: Disadvantages of air-cooled engines are that they: Are less efficient, Are noisier, with greater air flow requirements and no water jacket to dampen the noise, Need a directed air flow and finned surfaces. Advantages: When compared with liquid-cooled engines, air-cooled engines have the following advantages: They are lighter in weight, They cost less, No coolant system failures (e.g., water pump, hoses), No engine freeze-ups, and Faster engine warmup. Liquid-Cooled Engines: In a liquid or water-cooled engine, the engine block is surrounded by a water jacket through which the coolant flows. This allows for a better control of the heat removal from the engine, just by added weight and a more complex system. Very few water-cooled engines use just water as the cooling fluid in the water jackets; this is because the water has a freezing temperature of 0Â °C which is unacceptable as coolant in colder regions, so additives are usually used for better performance. Although water has very good heat transfer properties, but when used alone, it causes rust and corrosion in many of the pipes of the cooling system. Ethylene glycol (C2H6O2) is the antifreeze agent which acts as a rust inhibitor and a lubricant for the water pump. When added to water, it lowers the freezing temperature and raises the boiling temperature of the coolant. The properties of the mixture depend on the ratio in which water and the antifreeze agent are mixed. Pure ethylene glycol should not be used, and even at high concentrations the heat transfer properties of the water are lost as well. The properties of the ethylene glycol water mixture are shown in the table below. In addition to good thermal properties, a coolant should satisfy the following requirements: 1. Chemically stable under conditions of use 2. Non-foaming 3. Non-corrosive 4. Low toxicity 5. Non-flammable 6. Low cost Most commercial antifreezes satisfy these requirements. Many of them are basically ethylene glycol with small amounts of additives. Some commercial engine coolants use propylene glycol as the base ingredient. It is argued that when coolant systems leak or when the coolant becomes aged and is discarded, these products are less harmful to the environment than ethylene glycol. Basic Components: The basic components of a liquid-cooled system is shown below. Figure . Basic liquid-cooled system radiator radiator top hose radiator bottom hose water pump thermostat thermostat housing electric cooling fan thermo-time switch Radiator: The radiator is the part of the cooling system which is responsible for the heat rejection from the coolant and into the atmosphere. The radiator core is usually made up of flattened tubes with aluminum strips (fins) that zigzag between the tubes. These fins effectively transfer the heat contained in the coolant into the air stream to be lost into the atmosphere. On each end of the radiator is a tank made up of plastic to cover the ends. The tubes either run horizontally or vertically between the two tanks. The aluminum-plastic system is more efficient and cost effective. On radiators with plastic end caps, there are gaskets between the aluminum core and the plastic tanks to seal the system and keep the fluid from leaking out. The tanks have a large hose connection, one mounted towards the top of the radiator to let the coolant in, the other mounted at the bottom of the radiator on the other tank to let the coolant back out. On the top of the radiator is an additional opening that is capped off by the radiator cap. Another component in the radiator for vehicles with an automatic transmission is a separate tank mounted inside one of the tanks. Fittings connect this inner tank through steel tubes to the automatic transmission. Transmission fluid is piped through this tank inside a tank to be cooled by the coolant flowing past it before returning to the transmission. Radiator Fans: One or two electric fans are mounted on the back of the radiator close to the engine. These fans used the concept of forced convection to cool the heated coolant going through the pipes in the radiator core. If noticed, this fan starts working once the engine reaches a predefined temperature, after which the cooling by just natural convection during the forward motion of the car cannot be achieved. In the cars with air conditioning, there is an additional radiator mounted in front of the normal radiator. This radiator is called the air conditioner condenser, which also needs to be cooled by the air flow entering the engine compartment. As long as the air conditioning is turned on, the system will keep the fan running, even if the engine is not running hot. This is because if there is no air flow through the air conditioning condenser, the air conditioner will not be able to cool the air entering the interior. Pressure cap reserve tank: The pressure cap is simply a cap which maintains the pressure in the cooling system up to a certain point. If the pressure builds up higher than the set pressure point, the spring loaded valve releases the pressure. Figure . Pressure cap When the pressure in the cooling system reaches the point when the cap needs to release this excess pressure, some amount of coolant is bled off. The coolant which is bled off goes into the reserve tank which is not pressurized, which causes a partial vacuum in the cooling system. The radiator cap on these closed systems has a secondary valve which allows the vacuum in the cooling system to draw the coolant back from the reserve tank into the radiator. Coolant Pump: It is a simple pump which helps in circulation of the coolant around the system. This pump is run using one of the following: A fan belt that will also be responsible for driving an additional component like an alternator or power steering pump A serpentine belt, which also drives the alternator, power steering pump and AC compressor among other things. The timing belt that is also responsible for driving one or more camshafts. The impeller of the pump uses centrifugal force to draw the coolant in from the lower radiator hose and send it under pressure to the engine block. A gasket seals the water pump to the engine block and prevents the flowing coolant from leaking out where the pump is attached to the block. Thermostat: The thermostat is simply a valve that measures the temperature of the coolant, and if the coolant is hot enough it opens to allow the coolant to flow through the radiator otherwise the flow to the radiator is blocked and the fluid is directed to a bypass system that returns the coolant to the engine. Figure . Thermostat The engine is at times allowed to run at higher temperatures of 190-195Â °C; this reduces emissions, moisture condensation inside the engine is quickly burned off improving engine life, and a more complete combustion improving fuel economy. Oil as a Coolant: The oil when used to lubricate the engine also helps to cool the engine. The piston for example gets very little cooling from the coolant in the water jacket or the externally finned surface, so when the back surface of the piston crown is subjected to the oil splash or flow the piston is cooled to some extent. This is very necessary as the piston is one of the hottest elements in the engine. Usually, the oil is sprayed in pressurized systems, and splashed in non-pressurized systems. The oil acts as the coolant on the back face of the piston crown as it absorbs energy and then runs back into the larger reservoir where it mixes with the cooler oil and dissipates this energy into the other engine parts. This splash cooling of the piston is extremely important in small air-cooled engines as well as in automobile engines. A few other engine components other than the piston are also cooled by oil circulation, either by splash or by the pressurized flow from the oil pump. Oil passages through internal components like the camshaft and connecting rods offer the only major cooling these parts are subjected to. As the oil cools the various components, it absorbs energy and its temperature rises. This energy is then dissipated to the rest of the engine by circulation and eventually gets absorbed in the engine coolant flow. Some high-performance engines have an oil cooler in their lubricant circulation system. The energy absorbed by the oil as it cools the engine components is dissipated in the oil cooler, which is a heat exchanger cooled by either engine coolant flow or external air flow. Oil Pump: The gear-type oil pump has a pair of meshing gears. The spaces between the teeth are filled with oil when the gears unmesh. The oil pump obtains oil from the oil pan and sends oil through the oil filter to the oil galleries and main bearings. Some oil passes from the holes in the crankshaft to the rod bearings. Main bearings and rod bearings are lubricated adequately to achieve their desired objectives. In the rotor type oil pump, the inner rotor is driven and drives the outer rotor. As the rotor revolves, the gaps between the lobes are filled with oil. When the lobes of the inner rotor move into the gaps in the outer rotor, oil is forced out through the outlet of pump. An oil pump can also be driven by a camshaft gear that drives the ignition distributor or by the crankshaft. Oil Pan: Oil also flows to the cylinder head through drilled passages that make up the oil gallery, lubricates camshaft bearings and valves, and then returns to oil pan. Some engines have grooves or holes in connecting rods, which provide extra lubrication to pistons and walls of cylinders. Oil Cooler: Oil cooler prevents overheating of oil, by flow of engine coolant past tubes carrying hot oil. The coolant picks excess heat and carries it to the radiator. Oil Filter: The oil from oil pump flows through oil filter before reaching the engine bearings. The oil filter retains the dirt particles and allows only clean filtered oil to pass. The Lubrication system and its types: There are three basic types of oil distribution systems used in engines: Splash, Pressurized, or A combination of these. The crankcase is used as the oil sump (reservoir) in a splash system, and the crankshaft rotating at high speed in the oil distributes it to the various moving parts by splash; no oil pump is used. All components, including the valve train and camshaft, must be open to the crankcase. Oil is splashed into the cylinders behind the pistons and onto the back of the piston crowns, acting both as a lubricant and a coolant. Many small four-stroke cycle engines (lawn mowers, golf carts, etc.) use splash distribution of oil. An engine with a pressurized oil distribution system uses an oil pump to supply lubrication to the moving parts through passages built into the components. A typical automobile engine has oil passages built into the connecting rods, valve stems, push rods, rocker arms, valve seats, engine block, and many other moving components. These make up a circulation network through which oil is distributed by the oil pump. In addition, oil is sprayed under pressure onto the cylinder walls and onto the back of the piston crowns. Most automobiles actually use dual distribution systems, relying on splash within the crankcase in addition to the pressurized flow from the oil pump. Most large stationary engines also use this kind of dual system. Most aircraft engines and a few automobile engines use a total pressurized system with the oil reservoir located separate from the crankcase. These are often called dry sump systems (i.e., the crankcase sump is dry of excess oil). Aircraft do not always fly level, and uncontrolled oil in the crankcase may not supply proper lubrication or oil pump input when the plane banks or turns. A diaphragm controls the oil level in the reservoir of a dry sump system, assuring a continuous flow into the oil pump and throughout the engine. Figure . Lubrication of an engine consisting of a combination of a pressurized system and splash system Oil pumps can be electric or mechanically driven off the engine. Pressure at the pump exit is typically about 300 to 400 kPa. If an oil pump is driven directly off the engine, some means should be built into the system to keep the exit pressure and flow rate from becoming excessive at high engine speeds. A time of excess wear is at engine startup before the oil pump can distribute proper lubrication. It takes a few engine cycles before the flow of oil is fully established, and during this time, many parts are not properly lubricated. Adding to the problem is the fact that often the oil is cold at engine startup. Cold oil has much higher viscosity, which further delays proper circulation. A few engines have oil preheaters which electrically heat the oil before startup. Some engines have pre-oilers that heat and circulate the oil before engine startup. An electric pump lubricates all components by distributing oil throughout the engine. It is recommended that turbocharged engines be allowed to idle for a few seconds before they are turned off. This is because of the very high speeds at which the turbocharger operates. When the engine is turned off, oil circulation stops and lubricated surfaces begin to lose oil. Stopping the oil supply to a turbocharger operating at high speed invites poor lubrication and high wear. To minimize this problem, the engine and turbocharger should be allowed to return to low speed (idle) before the lubrication supply is stopped. Lubrication system in 2-stroke engines: Many small engines and some experimental two-stroke cycle automobile engines use the crankcase as a compressor for the inlet air. Automobile engines which do this generally have the crankcase divided into several compartments, with each cylinder having its own separate compressor. These engines cannot use the crankcase as an oil sump, and an alternate method must be used to lubricate the crankshaft and other components in the crankcase. In these engines, oil is carried into the engine with the inlet air in much the same way as the fuel. When the fuel is added to the inlet air, usually with a carburetor, oil particles as well as fuel particles are distributed into the flow. The air flow then enters the crankcase, where it is compressed. Oil particles carried with the air lubricate the surfaces they come in contact with, first in the crankcase and then in the intake runner and cylinder. In some systems (model airplane engines, marine outboard motors, etc.), the oil is premixed with the fuel in the fuel tank. In other engines (automobiles, some golf carts, etc.), there is a separate oil reservoir that feeds a metered flow of oil into the fuel supply line or directly into the inlet air flow. Fuel-to-oil ratio ranges from 30:1 to 400:1, depending on the engine. Some modern high-performance engines have controls which regulate the fuel-oil ratio, depending on engine speed and load. Under conditions of high oil input, oil sometimes condenses in the crankcase. Up to 30% of the oil is recirculated from the crankcase in some automobile engines. It is desirable to get at least 3000 miles per liter of oil used. Most small lower cost engines have a single average oil input setting. If too much oil is supplied, deposits form on the combustion chamber walls and valves will stick (if there are valves). If too little oil is supplied, excess wear will occur and the piston can freez e in the cylinder. Engines that add oil to the inlet fuel obviously are designed to use up oil during operation. This oil also contributes to HC emissions in the exhaust due to valve overlap and poor combustion of the oil vapor in the cylinders. New oils that also burn better as fuel are being developed for two-stroke cycle engines. Some two-stroke cycle automobile engines and other medium- and large-size engines use an external supercharger to compress inlet air. These engines use pressurized/ splash lubrication systems similar to those on four-stroke cycle engines with the crankcase also serving as the oil sump. Lubricating Oil: The oil used in an engine must serve as a lubricant, a coolant, and a vehicle for removing impurities. It must be able to withstand high temperatures without breaking down and must have a long working life. The development trend in engines is toward higher operating temperatures, higher speeds, closer tolerances, and smaller oil sump capacity. All of these require improved oils compared to those used just a few years ago. Certainly, the technology of the oil industry has to continue to improve along with the technology growth of engines and fuel. Early engines and other mechanical systems were often designed to use up the lubricating oil as it was used, requiring a continuous input of fresh oil. The used oil was either burned up in the combustion chamber or allowed to fall to the ground. Just a couple of decades back, the tolerances between pistons and cylinder walls was such that engines burned some oil that seeped past the pistons from the crankcase. This required a periodic need t o add oil and a frequent oil change due to blowby contamination of the remaining oil. HC levels in the exhaust were high because of the oil in the combustion chamber. Modern engines run hotter, have closer tolerances which keep oil consumption down, and have smaller oil sumps due to space limitations. They generate more power with smaller engines by running faster and with higher compression ratios. This means higher forces and a greater need for good lubrication. At the same time, many manufacturers now suggest changing the oil every 6000 miles. Not only must the oil last longer under much more severe conditions, but new oil is not added between oil changes. Engines of the past that consumed some oil required periodic makeup oil to be added. This makeup oil mixed with the remaining used oil and improved the overall lubrication properties within the engine. The oils in modern engines must operate over an extreme temperature range. They must lubricate properly from the starting temperature of a cold engine to beyond the extreme steady-state temperatures that occur within the engine cylinders. They must not oxidize on the combustion chamber walls or at other hot spots such as the center crown of the piston or at the top piston ring. Oil should adhere to surfaces so that they always lubricate and provide a protective covering against corrosion. This is often called oiliness. Oil should have high film strength to assure no metal-to-metal contact even under extreme loads. Oils should be non-toxic and non-explosive. Some desired qualities of Lubrication oil: Lubricating oil must satisfy the following needs: Lubrication. It must reduce friction and wear within the engine. It improves efficiency by reducing the friction forces between moving parts. Coolant Removal of contaminants Enhancement of ring seal and reduction of blowby Slow corrosion Stability over a large temperature range Long life span Low cost Hydrocarbon Components in Lubricating oil: The basic ingredients in most lubricating oils are hydrocarbon components made from crude oil. These are larger molecular weight species obtained from the distillation process. Additives: Various other components are added to create a lubricant that will allow for the maximum performance and life span of the engine. These additives include: Antifoam agents: These reduce the foaming that would result when the crankshaft and other components rotate at high speed in the crankcase oil sump. Oxidation inhibitors: Oxygen is trapped in the oil when foaming occurs, and this leads to possible oxidation of engine components. One such additive is zinc dithiophosphate Pour-point depressant Antirust agents Detergents: These are made from organic salts and metallic salts. They help keep deposits and impurities in suspension and stop reactions that form varnish and other surface deposits. They help neutralize acid formed from sulfur in the fuel. Anti-wear agents Friction reducers Viscosity index improvers Rating of Lubricating Oils and grades: Lubricating oils are generally rated using a viscosity scale established by the Society of Automotive Engineering (SAE). The higher the viscosity value, the greater is the force needed to move adjacent surfaces or to pump oil through a passage. Viscosity is highly dependent on temperature, increasing with decreasing temperature. In the temperature range of engine operation, the dynamic viscosity of the oil can change by more than an order of magnitude. Oil viscosity also changes with shear, decreasing with increasing shear. Shear rates within an engine range from very low values to extremely high values in the bearings and between piston and cylinder walls. The change of viscosity over these extremes can be several orders of magnitude. Common viscosity grades used in engines are: SAE 5 SAE 10 SAE 20 SAE 30 SAE 40 SAE 45 SAE 50 Common oils available include: SAE 5W-20 SAE 10W-40 SAE 5W-30 SAE 10W-50 SAE 5W-40 SAE 15W-40 SAE 5W-50 SAE 15W-50 SAE 10W-30 SAE 20W-50 Synthetic Oils: A number of synthetically made oils are available that give better performance than those made from crude oil. They are better at reducing friction and engine wear, have good detergency properties which keep the engine cleaner, offer less resistance for moving parts, and require less pumping power for distribution. With good thermal properties, they provide better engine cooling and less variation in viscosity. Because of this, they contribute to better cold-weather starting and can reduce fuel consumption by as much as 15%. These oils cost several times as much as those made from crude oil. However, they can be used longer in an engine, with 24,000 km (15,000 miles) being the oil change period suggested by most manufacturers. Available on the market are various oil additives and special oils that can be added in small quantities to standard oils in the engine. These claim, with some justification, to improve the viscous and wear resistance properties of normal oils. One major improvement that some of them provide is that they stick to metal surfaces and do not drain off when the engine is stopped, as most standard oils do. The surfaces are thus lubricated immediately when the engine is next started. With standard oils it takes several engine rotations before proper lubrication occurs, a major source of wear. Oil filters: Included in most pressurized oil systems is a filtration system to remove impurities from the engine oil. One of the duties of engine oil is to clean the engine by carrying contaminant impurities in suspension as it circulates. As the oil passes through filters that are part of the flow passage system these impurities are removed, cleaning the oil and allowing it to be used for a greater length of time. Contaminants get into an engine in the incoming air or fuel or can be generated within the combustion chamber when other than ideal stoichiometric combustion occurs. Dust and other impurities are carried by the incoming air. Some, but not all, of these are removed by an air filter. Fuels have trace amounts of impurities like sulfur, which create contaminants during the combustion process. Even pure fuel components form some contaminants, like solid carbon in some engines under some conditions. Many engine impurities are carried away with the engine exhaust, but some get into the interior of the engine, mainly in the blowby process. During blowby, fuel, air, and combustion products are forced past the pistons into the crankcase, where they mix with the engine oil. Some of the water vapor in the exhaust products condenses in the crankcase, and the resulting liquid water adds to the contaminants. The gases of blowby pass through the crankcase and are routed back into the air intake. Ideally, most of the contaminants are trapped in the oil, which then contains dust, carbon, fuel particles, sulfur, water droplets, and many other impurities. If these were not filtered out of the oil, they would be spread throughout the engine by the oil distribution system. Also, the oil would quickly become dirty and lose its lubricating properties, resulting in greater engine wear. Figure . Oil Filter Flow passages in a filter are not all the same size but usually exist in a normal bell-shaped size distribution. This means that most larger particles will be filtered out as the oil passes through the filter, but a few as large as the largest passages will get through. The choice of filter pore size is a compromise. Better filtration will be obtained with smaller filter pores, but this requires a much greater flow pressure to push the oil through the filter. This also results in the filter becoming clogged quicker and requiring earlier filter cartridge change. Some filter materials and/or material of too small a pore size can even remove some additives from the oil. Filters are made from cotton, paper, cellulose, and a number of different synthetic materials. Filters are usually located just downstream from the oil pump exit. As a filter is used, it slowly becomes saturated with trapped impurities. As these impurities fill the filter pores, a greater pressure differential is needed to keep the same flow rate. When this needed pressure differential gets too high, the oil pump limit is reached and oil flow through the engine is slowed. The filter cartridge should be replaced before this happens. Figure . Exploded view of an Oil Filter Figure . Pore size distribution for common filters Sometimes, when the pressure differential across a filter gets high enough, the cartridge structure will collapse and a hole will develop through the cartridge wall. Most of the oil pumped through the filter will then follow the path of least resistance and flow through the hole. This short circuit will reduce the pressure drop across the filter, but the oil does not get filtered. There are several ways in which the oil circulation system can be filtered: 1. Full-flow oil filtration. All oil flows through the filter. The filter pore size must be fairly large to avoid extreme pressures in the resulting large flow rate. This results in some larger impurities in the oil. 2. Bypass oil filtration. Only part of the oil leaving the pump flows through the filter, the rest bypassing it without being filtered. This system allows the use of a much finer filter, but only a percentage of the oil gets filtered during each circulation loop. 3. Combination. Some systems use a combination of full-flow and bypass. All the oil first flows through a filter with large pores and then some of it flows through a second filter with small pores. 4. Shunt filtration. This is a system using a full-flow filter and a bypass valve. All oil at first flows through the filter. As the filter cartridge dirties with age, the pressure differential across it needed to keep the oil flowing increases. When this pressure differential gets above a predetermined value, the bypass valve opens and the oil flows around the filter. The filter cartridge must then be replaced before filtering will again occur. Solid lubricants, such as powd

Comparison of Linguistic Differences in the Film and Novel of A Clockw

Anthony Burgess’ A Clockwork Orange - Linguistic Differences in the Film and Novel A Clockwork Orange, written by Anthony Burgess, is experienced differently as a novel than it is as the movie directed by Stanley Kubrick. The heart of the difference between the two forms is expressed by Bakhtin: "The potential for [‘double-voiced discourse’ between the author and narrator] is one of the most fundamental privileges of novelistic prose, a privilege available neither to dramatic nor to purely poetic genres" (Bakhtin, 320).1 An entire dimension of the novel’s story is lost in the movie when Alex’s role is reduced from narrator to commentator. The ability of Burgess to speak indirectly to the audience through Alex is removed, and the perspective on the Clockwork world revealed through Nadsat, the language Alex speaks, is lost. However, this does not mean that the movie is less effective than, or an inferior medium to the novel. The main drive of the story remains in the movie form: Kubrick utilizes the means, such as a musical score and th e visual dimension, unique to the dramatic genre to find ways around the loss of Nadsat and first person narration. He also tries to maintain the twisted sense of humor found in the book while working to promote the audience’s understanding of Alex’s universe. Kubrick preserves the unusual opportunity A Clockwork Orange offers the audience—a chance to immerse itself in Alex’s character and actions, and have its "nastier propensities titillated" (Burgess ix)2 by Alex’s "ultra-violence", instead of being frightened away. In the novel, Burgess is able to speak indirectly through Alex’s narration, telling the reader about the novel’s political setting as well as revealing Alex’s (and perha... ... Nadsat, is lost. And with the loss of a large and comprehensive language such as Nadsat, goes part of Burgess’ voice. However, Kubrick does an excellent job of retaining the novel’s spirit and structure, even while offering his own interpretation. He takes advantage of the visual and auditory possibilities that the film medium presents to fill in the gap created by the removal of Nadsat, resulting in an accessible and satisfying movie. In both forms, A Clockwork Orange draws its audience into sympathizing with Alex and ultimately enjoying themselves as they "rape and rip by proxy" (Burgess ix). Works Cited 1. M.M.

Social Work and Data Protection

CYP3. 3: Understand how to safeguard the well being of children and young people 1. 2 Explain child protection within the wider concept of safeguarding children and young people Child protection is much more than safeguarding or protecting children from direct abuse. The ‘Safe action plan’ is a piece of legislation that is very similar to the outcome of the 10 year strategies which we have here in Northern Ireland. It shows an understanding that children need protected in a wider view of safeguarding and has recognised a number of aspects in areas of protection . Keeping children safe. . Crime and bullying . Forced marriage Missing children . Actively promoting their welfare in a healthy and safe environment. This action plan is designed to work in a more holistic nature and be more ‘child centred’ promoting a happy safe environment for the child, supporting the child in areas of social and emotional wellbeing, healthy eating e. g. Healthy eating vouchers, n o tolerance to bullying. 1. 3 Analyse how national and local guidelines, policies and procedures for safeguarding affect ‘day to day work with children and young people. As it is the responsibility that anyone who comes into the contact of children directly or indirectly have a duty to keep children safe. And have the ability to recognise if a child is at risk of harm or abuse the local guidelines, policies and procedures have some clear guideline responsibility exist to ensure children are protected. The table below shows the English equivalent to the ‘Department of Health, Social Services and Public Safety’(DHSPSS) which issues guidance for or four local health and social service boards in Northern Ireland. THE LINE OF RESPONSIBILITY TO ENSURE CHILDREN OR PROTECTED There is a multitude of services and people who work directly with children and are guided by regional policies such as professional nurses, doctors, social workers. Teachers, classroom assistants and education officers. Also those who offer leisure activities such as football coaches, piano teachers, drama club leaders etc. all of which will need to be familiar with their settings/ organisations policy and procedures. The policy and procedures in my setting is also based on the guidance of the DHSPSS. It is made available for all in the setting to be made aware of and to know how to follow.

English as Essay – Homosexuality in Vernon God Little

Explore Pierre’s presentation of ideas concerning homosexuality and teenagers in Vernon God Little. In the novel, ‘Vernon God Little’ by DCB Pierre we see the presentation of teenage life and also homosexuality through the characters of Vernon Little and Jesus Navarro. As the book was published eight years prior to us reading it, the views Pierre presents could be different to our own. Also, Pierre’s age and up bringing add to the way he portrays different aspects of life. I believe that in ‘Vernon God Little’ Pierre presents teenagers as rude, bad mannered and impatient and homosexuals in a negative light.We are introduced to Vernon’s character whilst he is in prison. Pierre’s lexis tells us straight away that Vernon is a teenager as ‘Don’t even try to guess who stood all Tuesday night in the road. Clue: snotty ole Mrs. Lechuga’ page 1. The colloquial language creates a sense of childishness, which is enhanced by the insults describing Mrs. Lechuga. The word ‘ole’ suggests that Vernon believes everyone to be old in contrast to him. This is shown throughout the novel as Pierre repeats the insult.Also, Pierre’s use of the colon represents how Vernon did not wait for an answer, but instead carries on his trail of thought, pointing towards an impatient nature which is associated with teenagers. This technique is shown again on the same page when Vernon is thinking back to ‘that ole black guy who was in the news last winter’ page 1. This story is also used to show Vernon’s discomfort in his current situation. Pierre cleverly uses the story so Vernon can avoid talking about his own situation, as if ignoring it will make it disappear.This can be linked with Jesus’ philosophical question to Vernon at the end of chapter two ‘that if things don’t happen unless you see them happening. ’ page 18. This signifies teenage attitude as th ey are both trying to shift the guilt and the blame- Jesus with the massacre he commits and Vernon with the fact he is wrongly in prison. Another essential moment to show teenage attitude is when Vernon is contemplating whether or not to phone Taylor. To decide a conclusion he flips a coin ‘it comes down heads which means I call her in Houston immediately. page 154. Pierre uses this technique to show the reader how Vernon is trying to shift any pressure he can as he is finding it hard to deal with being on the run and the death of his school mates. Furthermore, at the end of chapter one, suspicions begin to arise about Vernon’s sexuality ‘Regular boy then, are you son? Like your cars, and your guns? And your-girls? ’ page 10. Pierre’s choice of the word ‘regular’ shows the reader that the Martirio society is not accepting of homosexuals.This is supported by the homophobic attacks that people have had to suffer for years. In the past thre e years, one in five gay people have been subjected to homophobic hate crime (found http://www. guardian. co. uk/society/2008/jun/26/equality. gayrights) . Pierre also uses rhetorical questions here and does not give Vernon time to answer any questions except the one about girls. This suggests the idea that the interviewer was only interested in Vernon’s sexuality. This accusation adds strain to Vernon’s character as he is trying to be a ‘regular’ teenager.Vernon also keeps changing his middle name throughout the novel; this shows that he is having trouble accepting himself and also the situation that he is in. The way the name constantly changes is a metaphor for how society and Vernon’s situation keeps changing. For example, on page 2 Pierre calls him ‘Vernon Genius Little’. In context we see that Vernon mocks himself here which enhances the struggle for identity and how he is being punished for being different. Subsequently, we are a ble to see that Pierre uses his characters to question homosexuality, but he never has them ask about sexuality straight out.Instead they avoid the subject which is a reflection of society’s reaction towards homosexuality in 2003 – when the novel was published. A good example of this is when Vernon is being interviewed on page 10 ‘Examine Little’s clothes did you? ’ ‘Undergarments? ’ Pierre is also able to portray the communities view on homosexuality through the character of Barry Gurie. At the end of chapter six, Gurie is questioning Vernon and starts teasing him about Jesus and his pending sexuality – ‘You aint tossin the ham javelin all night long, thinkin of your meskin boy? Grr-hrr-hrr’ Page 60.Pierre’s use of vulgar imagery illustrates how the community feels towards homosexuality. The potential rejection adds to Vernon’s struggle for identity. The laughter at the end of the line indicates the pe ople in the community do not take homosexuality or teenagers seriously and think of them as things to laugh at. In the second chapter, Pierre introduces Jesus Navarro during a flashback of Vernon’s. The first accusation of his sexuality is how ‘they found him wearing silk panties’ page 16. This is very effeminate and leads reader to question his sexuality.Pierre also tells us how Jesus’ father instantly denies that his son wore the lingerie by choice- ‘his ole man says the cops planted them on him’ Page 16. The way Pierre mentions Mr. Navarro’s outrage at the underwear but not the loss of his son or the massacre could also symbolise how the community finds fault in Jesus as a person without paying respect to his life. It is symbolic of how people instantly find fault in others. Chapter two also subtly points out how Jesus was being sexually abused by Marion Nuckles and Dr. Goosens- ‘Nuckles recommended his to a shrink. Jesus got w orse after that. Page 17. Pierre’s use of a short sentence creates a sense of worry. It allows the reader to understand that Vernon was worried about Jesus without having to vocalise it. This relates back to Vernon’s pride and how teens are perceived as not caring and shouldn’t talk about their feelings. The allegations of Jesus’ abuse are confirmed at the end of the novel in the form of his suicide note-‘you sed it was love you batsards’ Page 275. The wrong spellings suggest that Jesus was uneducated which is a stereotype of those from other cultures forced to learn our own culture.Also the use of the word ‘bastards’ means a child born out of wedlock and Pierre used it here as it symbolises the bad relationships shared between Jesus and the elder men. The note is important to the plot as it seals that fate of Nuckles and Goosens. It shows that the police are able to prosecute Nuckles and Goosens. In conclusion, I feel that Pierr e perceives homosexuality in a bad light. This is because the three characters that were openly homosexual – Jesus, Nuckles and Goosens – do not get the stereotypical ‘happy ever after’ like the other characters.This could show that society’s prejudice views can manipulate people’s minds and force them to go to extreme lengths. He also presents teenagers in both good and bad ways which indicates that not every teenager is the same and Pierre could not pin point a single action which defined every single person. this is because teenagers are misunderstood by other people and Pierre wanted to reflect that in his writing.

How to Personalize Your Revision Checklist

How to Personalize Your Revision Checklist How to Personalize Your Revision Checklist How to Personalize Your Revision Checklist By Guest Author This is a guest post by Laura Hamby. If you want to write for Daily Writing Tips check the guidelines here. Everyone has their methods. I’ve read revision checklists all over the Internet, but still that didn’t stop me from coming up with my very own checklist. Why? Why not? Who knows better than I how I write? And while I will confess to incorporating items from the checklists of other authors, especially those who write in the genre I do (because I’m a big fan of learning from others), I also know the areas I need to pay attention to on the second/third, et cetera, go-round on my manuscript. The idea is not to revise your voice right out of your work. It is possible to do that if you’re not careful. You also don’t want to revise yourself so you wind up sounding like the person whose checklist you’ve borrowed for your own use. So, what did I consider when putting my personalized checklist together? I’m glad you asked. 1. Things my critique partner pings me on regularly. In the beginning, I had a crit partner who would whack my knuckles with her cyber ruler about head hopping. Stay in ONE point of view? It took me a while to figure it out, but eventually I caught on and now when I head hop, I KNOW what I’m doing. These things are subject to change as you grow as a writer. 2. Things I personally think I can and should do better. Several years ago, I gave myself a mission to use better, stronger verbs whenever and wherever I could. I took baby steps in the beginning, I’d write, then go back and check for passive, lackluster verbs. After a while, I moved on to refusing to use a wimpy verb in the rough draft, even if it meant I stared at the screen until I came up with something better. I like to think now that I’ve about got this licked- the verbs with verve come more easily than the verveless verbs now. As with number one, the items on this portion of your checklist will change, which is exactly what you want, as it shows that you’re growing as a writer. 3. Feedback I’ve received from editors. Hey, I figure if I’m lucky enough to get a rejection complete with what worked and what didn’t work for the editor, that’s as positive a rejection as you can get. And boy, how stupid would I be to discount what the editor has to say? 4. Those pesky generic things that should be on every revision checklist. You know, fun things like spelling, grammar, punctuation, looking for words that are words but are the wrong words. Example: â€Å"The hen is mightier than the sword.† These are what I like to call ‘Fun Typos’ because they often are worth at least a weak giggle, if not a full belly laugh when you find them. 5. Compositional/conventional aspects. Plot, flow, pacing, all threads tied off in a pretty bow, and so forth. 6. Have I stayed true to my voice? We all have a unique voice, but sometimes, it’s possible for it become lost when we try to be too clever or when we fight our way through a scene as if it were a paper bag we had to escape from using nothing but a dull toothpick. This is the part that is truly personal, above and beyond the conventions, like using periods to indicate the end of a statement, that we must observe. What questions can you ask yourself on your checklist that will resonate with how you write and what you write in regard to remaining true to your voice? Feel free to add or subtract from this list, and hey, if you come up with something to consider for creating your own personal revision checklist, let me know. I’m a big believer in being teachable and learning as much as I can about the craft of writing.

The importance of integrity, trust and honesty Essay

The importance of integrity, trust and honesty - Essay Example This enhances the chances for others to have confidence in you. In this regards, the three virtues mutually co-exist. An honest person is usually genuine, real and true. Living an honest life with integrity entails living openly and revealing your true self to other people. Absence of honesty hinders development of meaningful relationships. Honesty therefore, perpetuates self-respect as well as respect for others. It imbues life with candor and openness.

Cultural Studies abstract Essay Example | Topics and Well Written Essays - 500 words

Cultural Studies abstract - Essay Example Issues related to the original shape and authenticity of the tales of Kitaro in the graveyard are examined by comparing various forms of the story in Kami-Shibai and the variations generated during the transition from Kami-Shibai to rental Manga. These are based on researches on street Kami-Shibai and rental Manga. Creation in Kami-Shibai, which has no prior story documented, depends mainly on sequencing of images with speech language and reaction from the audience. Therefore, as for street Kami-Shibai, the accumulation of various versions as one story must be put into consideration. Orality, a main feature of Kami-Shibai, is subject to fundamental and crucial transformations due to changes in representation techniques and authorship during its transition to Manga. The consciousness and analysis of Manga readers are centered primarily on words or text. The recipients of Manga and animation tend to be categorized as fanatics and this makes the issue of popular culture use and ownership even more complex. This paper also tackles the authorship and ownership of popular culture in the age of technological media. The relationship between cultural likeness and transformation of media technology is discussed while the arguments of studies on â€Å"transmission† [densho] in Japanese folklore studies, anthropological resemblance, power in cultural studies, and creative similarities are examined in discussing actual copyright issues of Manga, digital copyright, and problems encountered in its creation on the

Youth Subcultures And Its Influence On Youth Media Essay

Youth Subcultures And Its Influence On Youth Media Essay About: This report intends to analyze the complex relationship between media and youth subculture and argues that subcultures can reproduced and constructed through the media. It therefore, states that the national media should take responsibility in the discourses that are used to represent youth groups and youth subcultures as they impact on the activities of broader youth communities worldwide. The cultural universe of young people is a complex and dynamic one (White, 1999) and there has always been a tendency among youth researchers to investigate the significant social changes that are being revealed through the experiences of contemporary youth (Leccardi Ruspini, 2006). Some of the earliest sociological researches on youth can be linked to the emergence of new forms of consumptions and distinct youth cultures that began to rise in the late 1950s. The changes in youth at this era were highly visible through music and fashion the young populations were consuming. This was viewed both as a result of the increase time available for leisure and personal resources (Leccardi Ruspini, 2006) as well as an attempt to create some symbolic meaning for self (White, 1999). In times of high unemployment where youth were caught in between the ideology of spectacular consumption promoted by the mass media and the traditional ideology of capitalism and the meritocratic work led to a pro liferation of empirical studies across a wide range of diverse issues from homelessness to unemployment, youth crime to street gang violence that engages in research relevant to both empirical and theoretical matters in order to stretch the conceptual boundaries in the contemporary society (White, 1993). Youth subcultures can be viewed as a response to the interaction between these different areas. This response is seen by some as an identity seeking reaction between resistance to consumerism created by the production based Puritanism and the new hedonism of post war consumption (White, 1993). This paper looks into the contemporary youth subcultures and the media discourse used in the representation of these subcultures. It is argued that such negative representations of youth subcultures would result in the popularization and re enforcement of activities rather than limiting or controlling such deviant behaviors and thereby confirming the labeling of a demonized and at risk youth groups. Further, reports supports the idea that the media interventions in crime and social problem areas can lead to misplaced reactive political resources in mythic rather than real social problem areas resulting in amplified and exacerbated social problems generating moral panics (White, 1999). A culture can be defined as designs for living that constitute peoples way of life (Macionis Plummer, 2008:128). The five components of culture identified by Macionis and Plummer (2008: 130) include; symbols, language, values, norms and material culture. Culture has several, often contradictory meanings that carries ambiguity that can be traced in its different uses throughout history (Brake, 1985). While the classical perspective views culture as a standard of excellence (high culture), others view culture as a way of life which expresses certain meanings and values attached with a particular way of life known as the low culture'(Williams, 1961, p. 57). It is this conceptualisation of low culture that is central to the development of subcultures as an analytical concept (Brake, 1985). Subcultures can be defined as a cultural pattern that set apart some segment of a societys population (Macionis Plummer, 2008: 139) or a social group which is perceived to deviate from the normative ideals of adult communities (Thornton, 1995: 2). The earliest use of subcultural theories within sociology can be linked to its application as a subdivision of a national culture (Gordon, 1947). Culture in this context was viewed as learned behaviour with emphasis on the effects of socialisation within the cultural subgroups of a pluralist society (Brake, 1985). In most of the Western world, studies of youth subcultures have been dominated by a tradition associated with the 1970s work of the Centre of Contemporary Cultural Studies, University of Birmingham, England (Thornton, 1995). The Birmingham subcultural studies tend to banish media and commerce from their definition of authentic culture seen media and commerce as incorporating subcultures into the hegemony and effectively dismantling them (Hedbige, 1978). Chicago School sociologists on the other hand were concerned on researching empirical social groups by taking precedence over their elaboration of theory and were mainly focused on the shadier recesses of polite society (Thornton, 1995). This report will look at subcultures as cultures that are labelled directly or indirectly by the media with a problematic authenticity and as media and commerce integral to the authentication of its cultural practices. Supporting this, A.K. Cohen states that a major determinant of subcultures among th e youth as what people do depending upon the problems they contended with (Cohen, 1955, p.51). Cultural theorists argue that what it means to be young should be seen in the context of its cultural significance indicating that it is the context of cultural significance that makes been young so distinctive and not the structural focus of society (Alan, 2007). That is, the context the youth are exposed to and the issues that their exposures carry play a significant role in the construction of a youths culture. When understanding the conflicts surrounding young people and the way they use public space, the media plays a central role by constituting and shaping the principal form of the public sphere and by gathering and distributing important public information (Thompson, 1994 in Sercombe, 1999). One may argue that there is no certain measure of the direct effects of media coverage on the public. However, there are often negative and powerful cultural effects of media produced by the constant flow of its commercialized imaginary fictions and stereotypical coverages that socially construct a moral and narrative set of offerings upon which the youth attempt to build their identities on (White, 1993). Not only in building identities, the youth tend to use these social constructions by the media also as a measure for their achievements and personal worth by simply deriving an identity from a set of meanings drawn on the basis of media constructed stimulations instead of their local experiences (Baudrillard, 1983). It is important to note that the notion of identities are constructed across and by differences, and the social construction of youth identities though historically varied is tightly bound with the media representations made available at the time (White,1999). Therefore, we can argue that media is a critical component of the development and maintenance of the representation of young people which often feeds into the fears and negative attitude surrounding the presence of young people in public space as problematic or threatening (Sercombe, 1999). Moral panics in relation to youth, music and subculture are not uncommon in the news and other current media (Goode Ben-Yehuda, 2008, pp. 124-145 in Journal of Media Culture). Most cities in Australia like many other cities around the world housed for a large number of subcultural activities ranging from skateboarders occupying the steps and benches in the Melbourne streets to Goths congregating the inner city suburbs (Gelder, 2007). It also has a number of drag night clubs, gay and lesbian bars, a remarkable graffiti subculture; in which Melbourne has been claimed as a stencil graffiti capital (Smallman Nyman, 2005). Australia has several times witnessed its teenage subcultures clash in the streets; like the Mods and Sharpies in August 1966 (Sparrow Sparrow, 2004: 73-77). Stan Cohens classic Folk Devils and Moral Panics (1980) and the centre for Contemporary Cultural Studies Policing the Crisis (Hall et al. 1978) both indicate how mainstream media contributes to the public anxiety about youth subcultures and youth groups that are deemed to be deviant. Cohen, in his work looks at the development of conflict between mods and rockers, in a British seaside town, and particularly the escalation of conflict that arose as a result of the medias representation of these events. He argues that the media were responsible for amplifying the perception of deviance arising from a few of small-scale disturbances, which ultimately led to an escalated interventions from the police and judiciary, with the demonization and over-typification of young people involved in the mod or rocker styles. Similarly in Australia Cunneen et al. 1989, carried out a study on the disturbances at the Bathurst motorcycle races concluding that it was the over representation of the small di sturbances that led to the large scale conflicts and that the press concentrated on authority opinion while sensationalizing the material published (Cunneen et al., 1989). When analysing the literature published on the media representations of youth and youth subcultures it is evident that communications media create subcultures in the process of naming them and drawing boundaries around them in the act of describing them (Thonrton, 1995). The way media is inextricably involved in the meaning making and organization of youth subcultures will be discussed through the analysis of the representations of many recent incidents related to youth subcultures, particularly the ravers, Goths and Emo subcultures. The rave subculture emerged worldwide in the late 1980s as a musical subculture and was a phenomenon in the area that attempted to invert the traditional rock n roll authenticity by remixing and creating a cutting edge disk culture with a warehouse party format and was established in Chicago, Detroit and across Britain (Thornton, 1995:4). Soon groups of young people were clustered in sites conventionally aligned with musical performance to listen and dance to electronic dance music played by djs in Sydneys alternative rock scene Unlike other musical subcultures such as alternative rock scene where performances generally took place in formal environments such as pubs and clubs the raves in Australian cities began to use spaces such as old warehouses, factories and train stations for their activities (Gibson Pagan, 2006). Since the late 1980s rave culture worldwide has increased their members and was diversified and fragmented in many aspects becoming more contradictory with various s ubcultures emerging such as the Doofs, Drum and Bass and Happy hard core. Mean while controversies and public moral panics were starting to generate over the diverged more politicized illegal party culture that were shifting itself from the mainstream (Gibson Pagen, 2006). Associations were made between these part scenes and illegal drugs such as ecstasy by the media providing the basis for a moral panic. Ravres were described as new age hippies where their activities summed up to no sex, but drugs and rock roll (Benette, 1999). Dance parties in Sydney eventually became associated with tropes of youth deviance and illegality making the rave space in the public consciousness as a site beyond the domain of mainstream, and thereby causing strong reactions from the public and a need for increased control over their events (Gibson Pagen, 2006). A major shift in the perception of the public of youth subcultures could be related to the ecstasy related death of teenager Anna Woods from Sy dney at an Apache party in 1995. Her death was magnified within the media creating an unprecedented wave of media attention and public panic. With headlines such as Ecstasy agony and Ecstasy secret world running on the front pages for nearly two weeks, dramatically altering not only the rave culture but the perception of youth subcultures as a whole (See Sydney Herald Sun, 4/3/2007). The initial response of sympathy by the public to the incident soon turned into fear and anger that progressed from tension and social anxiety to a full blown social and political crisis (McRobbie, 1994) with scapegoating not only the ravers but creating fear against many youth subcultures (see Daily Telegraph, 27/3/2007:73). The death of Anna was interpreted as a symptom of the malaise affecting many young Australians (Daily Telegraph, 5/11/1995:8), with the NSW state government taking actions to close down clubs and bars which have promoted drugs in parties (Gibson Pagen, 2006). For a few months in 2007, the dangers of emo and computer use were significant themes in Australian newspaper coverages (Phillipoy, 2009). Emo is an abbreviation of the terms emocore and emotional hardcore which is a musical subgenre of punk rock music, characterised by emotional or personal themes. They adopt a look that includes black stovepipe jeans, dyed black hair and side-parted long fringes, which might merely have been one of the many tribes (Bennett, 1999) that characterise this contemporary youth culture(Phillipoy, 2009). Following the deaths of Melbourne teenagers, Jodie Gater, Stephanie Gestier and Carly Ryan in 2007, over an approximately five months period the media portrayed the two separate incidents linking the suicide and the murder to the emo subculture and to the social networking site MySpace, presenting both as dangerous and worrying developments in contemporary youth culture (Phillipoy, 2009). These media discourses surrounding the deaths included many features of moral panic uncluding a build-up of concern disproportionate to real risk of harm (see Goode Ben-Yehuda, 2002, pp.33-41). While the emo youth were viewed as straightforward folk devil (Cohen, 1972) or the enemy, the problem of emo was also framed as a product of much broader problems of youth culture (Goode Ben-Yehuda, 2002). The connections between emo and the deaths of these young girls were tenuously published over the mass media and was seen as symptomatic of what John Hartley (1998) describes in the context of reporting o n young people more generally as a profound uncertainty in the textual system of journalism about where the line that defines the boundary of the social should be drawn by the broader groups of non-subculturaly affiliated youth. The result of this according to Phillipoy, is a cultural thinking out loud (Hartley, 1998) where broader cultural anxiety are expressed and explored that can be described as anxiety about disclosure. The newspaper coverages on the deaths focused on the dangers of young peoples disclosures that made them inaccessible to adult authority that otherwise could have prevented the tragedies. Though some of these concerns were connected to the specificities of emo subcultural expression, with excessive emotions on display and the enigma associated with subcultural imagery respectively, they were on the whole linked to a broader problem in contemporary youth culture that was seen to apply to all young people, irrespective of any subcultural affiliation. The expressio ns of anxieties that the private lives of young people were becoming increasingly unknowable to adult authorities, and, hence, that youth culture itself was increasingly unknowable were popular statements made by the media (Phillipoy, 2006). Reportings such as bizarre teenage goth and emo world world constructed both as dangerous (in the sense that her apparent involvement in subcultural activities was presented as disturbing and something that put her at risk of harm) and impenetrable (in the sense that subcultural imagery was understood not simply as harmful but also as bizarre). In conclusion, the representations of young people in the media directly or indirectly depend on the interest of the newspapers and the discourse of its source. Language used by these media allows painting young people in different colors (Sercombe, 1999) and as youth subcultures are prime fare for the news media as in terms of news value they are both exotic and familiar (White, 1993) media and youth subcultures have a complex and symbolic relationship where young people are devoted consumers and producers of media and engage with media in the approval and adaptation of subcultural forms for their own context. Therefore, many of the subcultures can be argued to be reproduced and constructed through the media (White, 1999). The mainstream media however tend to represent youth subcultures mythologically as they often attempts to represent not the real world but the world that suits the advertisers, owners and the government. This leads to the constant stereotyping, reinforcing and exa ggerating issues, particularly in relation to the youth (White, 1993). Youth was portrayed within the media as the mindless hedonism of lost youth and were categorized as a careless generation that was only concerned with seeking pleasure and satisfaction from personal risk taking and drug use (Brown, 2005 in Allan 2007). By constructing notions of deviance and illegality, commercial media not only position youth and youth subcultures but are implicated in defining authentic underground activities that further strengthen subcultural practices that are deemed deviant (Gibson Pagan, 2006). Therefore, it is clear that media have been and is today, a major influence in fuelling and reinforcing perceptions of problem youth. Subcultures are constructed and stereotyped by the media as deviant and the media representations linked to the issues around subcultures have created an image of uncaring, hedonistic and self centered youth (Alan, 2007). Hence, this report suggest that the media is directly or indirectly responsibility for the fuelling and reinforcing of such deviant activities that they have constructed aligned to youth subcultures and that youth subcultures are a social construction mainly influenced by the national mass media. Therefore, the national media, particularly newspapers as the most commo nly used news media has a responsibility in the a discourses that are used to represent youth groups and youth subcultures as it carries an impact on the broader youth communities worldwide.
