Christmas Dinner

ENGL 1301 – Section 4 Narrative essay June 13, 2012 The Making of Christmas Dinner â€Å"Caitlyn, get downstairs now! † frantically screamed my mother. The sound of her nervous voice made me spring from the bed and quickly scramble down the stairs to the kitchen. As I slid around the corner and headed toward the kitchen, I encountered a large, foggy cloud of strong smoke. â€Å"Mom, what’s going on? † I screeched. She was grabbing the bright red fire extinguisher from under the sink to avert the fire coming from the oven. She opened the oven door to see flames coming from our Christmas turkey.Flames were leaping out from the roaster pan when she unleashed the fire extinguisher dousing the smoldering carcass. I didn’t understand what had happened. It was Christmas Eve morning, and my mom had been working on the special plans for a family dinner for days. By this time, my sisters were also in the kitchen, wondering what was causing such a commotion. W e all agreed that the turkey was as good as road kill. Mom dumped the turkey in the outside trash barrels and came back into the kitchen to decide how we could switch to an alternative plan.As the awful smell of burned turkey filled the kitchen, mother explained that she had forgotten to reduce the temperature of the oven before she went to bed last night. We were all grateful the whole kitchen wasn’t on fire! I felt horrible for my mom. This was going to be the first year to have the entire family come to our house for dinner. We all looked at each other with the question, â€Å"What are we going to do? † My mom said that she and my dad could drive to Tyler to buy a Greenburg turkey already cooked. That sounded like the best plan. However,† she added, â€Å"you girls will have to finish the side dishes. † We all looked at each other with uneasy expressions on our faces. Could we do this? Without really thinking about what we were agreeing to do, we said, â€Å"Oh yes, we can do that. † Before mom left for Tyler, she gave us the entire menu she had planned: green beans, mashed potatoes, our favorite macaroni and cheese, and yeast rolls. Aunt Kelley was bringing the fruit salad. Aunt Joyce was bringing her special cranberry salad. Our grandmother was bringing her favorite pecan pie and our great randmother was bringing her famous banana pudding. My sisters and l agreed we would make gingerbread cookies to add to the wonderful dessert assortment. As our parents drove out of sight toward Tyler, we girls went to work. We divided the responsibilities and went to our work spaces in the kitchen. Ashley got the green beans started by opening the huge can of Italian green beans mom had bought at Sam’s Wholesale. It looked like we could feed the whole army with all those beans. She added lots of butter with salt & pepper. As they began to boil, she lowered the heat and put a lid on the pot.Lauren was peeling potatoes at the sink. When she finally finished peeling all the potatoes, she began cutting them into slices and put them into a large pot of water to boil. I was busy getting the boxes of macaroni opened to add to the boiling water I had already started. Adding a dash of salt, I lowered the heat under the bubbling macaroni hoping it would not boil over onto the stove. I figured we had already had enough catastrophes for one day. While the macaroni noodles were boiling, I sliced the creamy Velveeta cheese that would be added to complete our favorite side dish.We were amazed that everything was cooking so quickly and the smell of burned turkey was being replaced with a much more appetizing aroma. When all of our assigned dishes were completed, we all decided we could work together to make the gingerbread cookies. We had helped our mother make cookies since we were little girls so we felt more comfortable with this chore. My mom had already made the dough for the cookies, so we were left with the fun part †¦rolling and cutting the little gingerbread men. Ashley found the cookie cutter while Lauren began rolling the dough.I gathered all the cookie sheets we would need to make everyone in our family their own gingerbread cookie. Lauren had the dough all rolled out on the cabinet and we all took turns cutting out the little men. We gently lifted each cookie and placed them on the baking sheets. They looked like little children all in a row with their arms outstretched to welcome our guests. As the cookies were placed in the warm oven, we began to gather the decorations needed to create the image of one of our favorite storybook characters, â€Å"The Little Gingerbread Boy. The cookies smelled wonderful baking in the oven. We had been careful to set the timer so the cookies would not burn. When the cookies were baked and cooled, we began making tiny smiling faces with bright eyes on each little gingerbread man. Ashley found a large crystal dish to arrange the finished cookies for a n impressive presentation. They were so cute, we decided to leave them out on the dessert table for everyone to see as they arrived. We gathered all of my mom’s special china serving bowls to compliment each of the side dishes we had prepared.When our parents returned home with the beautiful Greenburg turkey, they were overwhelmed with all the side dishes we had prepared and had placed in the warming oven to await our guests. We didn’t confess that we had made a quick trip to The Farm House for the wonderful yeast rolls. We decided that detail could wait until after dinner. All of us gathered the red and green Christmas dishes with a decorated tree in the center of each plate so each guest would have a special place at the table.Dad helped set the silver at each plate and my mom reached to the top shelf of the china cabinet to get their wedding gift crystal glasses. What began as a nightmarish day had turned into a wonderful Christmas memory. As our relatives began to gather bringing their personal additions to the dinner, we were all reminded of why this celebration is our favorite day of the year. We had all come together to share our love for each other and be grateful for the many blessings we shared as a family.

How Does the Practical Life Exercises Help Children in Their Daily Living? by Maria Montessori

Reason for Practical Life ExercisesChildren are naturally interested in activities they have witnessed. Therefore, Dr. Montessori began using what she called â€Å"Practical Life Exercises† to allow the child to do activities of daily life and therefore adapt and orientate himself in his society.It is therefore the Directress’s task to demonstrate the correct way of doing these Exercises in a way that allows the child to fully observe the movements. Montessori says, â€Å"If talking don’t move, if moving don’t talk†.The directress must also keep in mind that the goal is to show the actions so that the child can go off and repeat the activity in his own successful way. Montessori says, â€Å"Our task is to show how the action is done and at the same time destroy the possibility of imitation†. The child must develop his own way of doing these activities so that the movements become real and not synthetic.During the child’s sensitive peri od between birth and 6, the child is constructing the inner building blocks of his person. It is therefore important for the child to participate in activities to prepare him for his environment, that allow him to grow independently and use his motor skills, as well as allow the child to analyze difficulties he may have in the exercise and problem solve successfully.Montessori also saw the child’s need for order, repetition, and succession in movements. Practical Life Exercises also helps to aid the child to develop his coordination in movement, his balance and his gracefulness in his  environment as well as his need to develop the power of being silent.Dr. Maria Montessori developed her philosophy of education based upon actual observations of children. She said children prefer work than play, and they can only be in their natural self, when their natural self is satisfied through work. It's also through work they acquire independence, order, the power of concentration and be normalized. Exercises of Practical Life was introduced and was recognized as the very heart of Montessori Education for it provides the opportunity for the child’s development of physical co-ordination, social skills, emotional growth as well as cognitive preparation.Having a rich and stimulating prepared environment equipped with purposeful materials and trained teachers are important for the child to grow to their full potential. Practical Life Activities are the first activities the child is introduced to within the Montessori environment. These exercises are prepared based on activities children witnesses in their day to day life. That is why children can immediately satisfy their inner needs and desires by mastering these exercises independently. Also Practical Life area allows children to do the things what adults do everyday, for example cleaning, dressing or greeting people. As we know that children construct their knowledge by themselves through their life experi ence.Categories of Practical Life ExercisesPractical Life Exercises are grouped into four categories, development of motor skills, care of environment, care of self and social grace and courtesy. Exercises in each of these categories provide the opportunity to do purposeful work and are designed to teach the child life skills, so that they may become confident to do their daily chores at home. Activities grouped under ‘Development of Motor Skills’, such as carrying, pouring, squeezing, and twisting, sorting, etc. give the opportunity to exercise and co-ordinate body movements of the child.Movement is very important to the child; because it contributes not only for the physical growth also intellectual and spiritual development of the child. â€Å"Through Movement, he acts upon his external environment and thus carries out his own personal mission in the world. Movement is not only an impression of the ego but it is an indispensable factor in the development of consciou sness, since it is  the only real means which places the ego in a clearly defined relationship with external reality.†The secret of ChildhoodThe child learns to ‘Care for the Environment’ from exercises like cutting, cleaning, washing, polishing, sewing and more. They learn that they are a part of the environment and learn to respect and develop a sense of responsibility towards the environment. Also the child will gradually learn how to gain greater control of his gross motor movements so that he would be able perform more complex tasks later on. Some of the activities such as washing of a table can be carried out as a group task, which helps the child to be socialized. The child needs to build himself and learn to take care of himself.The exercises in ‘Care of Self’ category are designed to provide the child skills need for his sole independence. In order to gain independence, the child needs to establish will and discipline in order. Some of the activities in this category are on how to dress himself and stay clean by washing himself; hands, face, feet as well as his belongings; shoes, napkins, etc.. Between the ages of 2 1/2 -6, the child is in a sensitive period for the learning of good manners.The exercises of ‘Grace and Courtesy’ are focused on developing will power, establish a proper posture, greet people, excuse one and interrupt when necessary. Maria Montessori considers the Social Grace and Courtesy activities as the most important exercises in the practical life curriculum. She felt that when children are first brought into a Montessori classroom, emphasis must be placed on social grace exercises.Motive of Practical Life ExercisesPractical Life Curriculum area has four main direct aims; Order, Co-ordination Independence and Concentration, Dr. Maria Montessori observed that children need order at a specific sensitive period in their development. If not provided during this period the opportunity is for egone. A routine is very important as well as a place for everything and everything in its place. This offers the child for orderly self construction. Co-ordination refers to coordinating large and small muscle movements as well as eye-hand co-ordination that reflect the respective development of child’s mental life. â€Å"Man achieves his independence by making efforts. To be able to do a thing without any help from others: this is independence. If it  exists, the child can progress rapidly; if it does not, his progress will be slow† The Absorbent Mind, chapter.XIV, pg 155It is very important that the child is given freedom to do these exercises at a time the child pleases; he should be allowed to try, make mistakes and correct his mistakes by himself without any help. The satisfaction of completing an activity drives the child towards independence. The power of Concentration is one of the most calming activities for a child. This is something which is controlled by the child and it challenges his body and his mind. With concentration the child is able to focus on purposeful work. I’ve witnessed to the concentration that my 3 and half year old niece had for folding her little brothers’ nappies.The pile of nappies was two times bigger than her, I thought, she would be bored and leave, but for my amazement after 45 minutes I could see that she has folded all nappies very neatly and have kept one on top of another and was ready to be placed in the drawers. Within the Montessori classroom deep concentration can be acquired through the ‘Silence Game†. To achieve silence requires effort and the attention of the will, and maximum control of self-consciousness of every movement. Montessori thought of the silence lesson as a means for bringing children to this higher level of spiritual awareness. Practical Life Exercises aid the child in his journey towards normalizationAs a result of learning Practical Life Exercises in the M ontessori environment, the child starts to develop confidence, self-esteem, he grow towards independence, mutual aid and co-operation, profound spontaneous concentration, attachment to reality and most importantly child's joy of learning is supreme. All these help the child to lead towards normalization. The normalized children possess a unique character and personality not recognized in young children Normalization is the most important single result of our whole work. The Absorbent Mind, Chapter XIX, pg. 204.Children needs a carefully prepared environmentIt is important to provide the child an environment to work on activities of their own choice at their own pace experiencing freedom and self discipline while developing towards independence. Even though materials in Practical  Life area are the least standardized, exercises needs to be carefully thought and designed. A prepared environment should consist of purposeful and meaningful materials and properly trained instructors. W hen preparing materials the teacher needs to consider few principles of the Montessori Practical Life materials which satisfy Childs’ development needs.Firstly she needs to make sure that each material we give the child should have a definite purpose, for an example the mat is laid to mark the area of his workstation, handling the spoon develops child’s skill of spooning which leads to independence. Secondly materials should progress from simple to more complex design and usage. As a preliminary exercise for transferring solid objects we could give the child a spoon and later, it could progress to tweezers, chopsticks. Also it should be designed to prepare the child indirectly for future learning’s such as writing, mathematics and scientific concepts.We prepare the child for wiring by teaching them the pincer grip, using thumb, index and middle fingers to hold objects and by left to right and top to bottom concepts, so that these orders naturally incarnates in t he child’s mind. The mathematical concepts such as judgement of capacity and volume, division, calculation and exactness includes in activities of spooning, pouring and sweeping. The activity, transferring water using a sponge gives the child the scientific concept of weight. The child could feel the weight of the sponge defers when the water is absorbed and when the water is released. Dr. Maria Montessori said, â€Å"Each individual should become aware of his own errors. Each should have a means of checking, so that he can tell if he is right or not.† Absorbent Mind, Chapter XXIV, pg 247.So she included the path to perfection, which she called â€Å"the Control of Error† within the materials itself so the child would be able to observe the activity he completes and understand his own mistakes. If a child has finished working on the dressing frame with large buttons, and he can see that buttons has gone through wrong buttonholes or buttoning halfway or seeing on ly half of the button come up the flap, these would be his control of errors. He has the opportunity to guide himself to correct his own mistakes. Furthermore when preparing the activity in the Montessori classroom the directress need to make sure that all materials are kept together in a basket or a tray and grouped accordingly to the level of  development.The activity should have its unique location and be reachable to the child so that the child could use the materials of their own choice and return the exercise, leading to independence and self-discipline. Also it is important to be providing attractive and clean child friendly and child size materials. Each activity should be limited in quantity. In a Montessori classroom the directress plays a major role. She needs to be properly trained, be a good role model and she should be able to develop and maintain a happy and rewarding teacher-child relationship. †The first essential is that the teacher should go thru an inner, spiritual preparation – cultivate certain aptitudes in the moral order.† Her Life and Work, Chapter XVIII, pg 298.The teacher's prime objectives are to: maintain order in the prepared environment, facilitate the development of the child, encourage independence and self-sufficiency. In conclusion it is apparent that Practical Life Exercises refines movement, providing a foundation in early learning, attitudes and dispositions. Practical life exercises also provide children a sense of accomplishment as they engage in real, meaningful work with tangible results. The familiar home-like environment of the practical life corner allows children to gain independence, order, concentration and confidence as they carry out thoughtfully prepared activities. This leads to normalization.

Intercultural Communication Paper Essay Example | Topics and Well Written Essays - 1500 words

Intercultural Communication Paper - Essay Example Most migrants have assimilated into America’s traditions and ways of life. Although conventional cultural values and beliefs have been preserved by the originating migrants, their children have completely adapted and adjusted to Western culture. It is interesting to delve into finding out the factors which contribute to the academic performance of migrants’ children, specifically Korean Americans. Adolescents from today’s generation have grown with relatively antithetical thinking and preferences compared to generations that their grandparents and parents were accustomed to. Likewise, academic performance, attitudes and behaviors of previous generations were influenced by communication, among others; as well as traditional and conventional norms. Communication is the â€Å"process of transmitting thoughts, feelings, facts, and other information† through verbal or non-verbal means. (Delaune and Ladner 2006) Verbal messages are messages communicated with the use of words and language. These messages can either be spoken or written. Non verbal communication, on the other hand, is the process of transmitting messages without words, that is, through body language. (Delaune and Ladner 2006). In this regard, the objective of this essay is to proffer a scenario which manifests the relevance of intercultural communication in the academe, affecting the performance of students from another culture, particularly from Korea. A review of literature would initially be presented delving into the effect of communication to cultural diversity. Likewise, the methodology used would be explained in determining the academic achievement of Korean-American adolescents in schools in the US where a hypothesis is developed. Finally, through the interview conducted and through secondary sources, the effect of family, communication and culture in the academic achievement of Korean-American adolescents

Business Environment Essay Example | Topics and Well Written Essays - 2500 words

Business Environment - Essay Example According to Leach (2002), the impacts of these policies on businesses can be short run or long run. Fiscal policies are used to influence levels of aggregate demand in the economy. For the supermarket case, it would be used to achieve price stability and employment regulation. If the government for instance increases its spending and decrease the taxes, then there will be an increase in aggregate demand for the grocery products in the economy (Leach). This brings economic boom to the industry. The increased aggregate demand may cause a need to increase supply hence invoking the need to increase employment. In this case, the supermarkets would at the end have to hire extra staff. When there is inflation in the economy, the government may try to stabilize the prices of the goods by reducing its expenditure, hence reducing aggregate demand forcing the businesses to reduce their prices, hence price stability in the whole economy. Crowding out effect is realized at times in this situatio n. Neri (2001) asserted that monetary policies highly influence the expenditure in an economy. When the central bank of any nation increases its lending rate to commercial banks in an economy, there will be a lag in the amount of money businesses can afford to borrow from the banks in turn due to the increased lending rates by commercial banks. Public sector spending is minimised at this time because of less money in circulation in the economy. Supermarket stores and other businesses will therefore have to reduce their expenditure since access to financial services from banks has been highly reduced (Neri). Impact of Competition Policy and Regulatory Mechanisms on Tesco Regulation of the grocery industry in the UK by nature of its competition is based on four major items; prices, location of the company, product selection and promotional procedures. The industry is regulated by the Fair Trading Act of 1973 which regulates the level of competition in the grocery industry. In analysin g the impacts of competition policy on Tesco PLC therefore, there has to be a consideration for the above four factors. In terms of entry into a market, the competition regulatory policies do not restrict acquisition. Tesco was experiencing completion in some areas and because of there being legislations on take-overs and barriers to entry, the small retailers were purchased by Tesco and therefore created more vivid market domination by this giant firm. According to the revised competition act of 1998 as indicated by a Lancaster university report†¦.†any merger, whether notified to the OFT or not, whether intended or consummated, can be referred by the Secretary of State (SoS) to the Competition Commission for investigation, provided it is above a threshold size†. It is like the act allows takeovers and mergers which kills competition from the small scale retailers. The second competition policy of great importance is the transparency policy. This is mainly applicabl e to the promotional industry. Tesco as a company uses the Tesco Clubcard to keep in touch with its customers. However, the act does not allow the company to remain discrete about its promotional contacts with its clients. This in some cases creates an implication of leaking private company information to the competitors. The third rule is on breach of regulatory rules and the consequences thereon. The Director General of Fair Trading has the express authority to investigate a breach. If a company is

Response to Hurricane Katrina Essay Example for Free

Response to Hurricane Katrina Essay On 29 August, 2005 the category 5 huge Hurricane, Hurricane Katrina hit USA land. This natural disaster brought massive flood, damaging the property and resulted into high death toll. Although the projects related to the protection of areas by Hurricane were constructed 60 years ago but this exceptional unexpected disaster was the most terrible one in USA history (GAO-06-934, 2006). The disaster of Hurricane Katrina was beyond the expectation of the officials of the emergency management, which resulted into delay in supporting the effected people and the area by the guards and military. This uncontrolled situation showed the absence of management and lack of the ability to take a quick action by the people responsible to handle the problem because of their unawareness of handling the situation (Cooper Block, 2005). Bureaucratic/ Hierarchical model vs. Network model Professor Charles Wise asserts that effective and efficient running of organizations can be achieved through a combination of strategies and techniques. He further states that the organization must utilize all its resources in order to achieve business goals (Wise, 2006). Wise laid importance for the implication of network model rather than the hierarchical model. He explains that in hierarchical model, the decisions take place at the top level without communicating all the levels of organization and there is no evaluation of the progress. Due to this, flaws and unfavorable situations results at the end. In network model, there is continuous flow of information between the different levels of organization, which brings good results in managing any emergency. Waugh and Streib also laid emphasis on the change in the hierarchical model in which only top management contributes in making the decision (2006). The failure in handling the hurricane Katrina showed the inability and flaw in the decision making of the hierarchical management (Takeda Helms, 2006). Adaptive Management Approach The approach of government organizations of dealing with the natural disaster created a negative impact on the people of America. It showed that serious steps need to be taken in managing any kind of disaster (Schneider, 2005). Applying adaptive management hypothetically following steps should be followed: †¢ All the problems should be discussed with the stakeholders. †¢ There should be no communication gap and the flow of the data should be continuous between all the levels of the organization. †¢ The strategies should be followed and monitored to get positive outcome. †¢ There should be monitored resources. †¢ Policies and procedure should be there and should be consistent. †¢ Activities for the future should be planned and communicated at all level of the organization and different ideas by all should be encouraged. The management approach to deal with the hurricane Katrina should be a strategic approach. People of the effected area should be informed and educated to deal with the situation. They should be moved to the safe place. Instruction should be communicated by the organization through T. V and other mode of communication before the occurrence of the hurricane. There should be a complete planning. Measures and goal should be set to deal with such natural disaster. There should be training provided to the people, responsible to handle the situation. The programs for the affected people and victims to overcome the situation and so that they can get back get back in normal condition should be introduced to deal with any emergency created by natural disaster. Recommended Management Approach An effective management approach utilizes different strategies and tactics in order to reduce or mitigate the impact of a natural disaster. The first step is that adequate preparations must be made for any emergency by the presence of specific contingency plans. Governments must devise long term and short term solutions that can assist in reducing the impact of natural disaster (Wisner, 2004). This could be through the use of technology and administrative regulations that could help and assist people during times of natural disaster. Emergency and civil services must be adequate and competent enough to effectively and efficiently respond to any natural disaster. They must ensure the provision of vital services for people who trapped or injured because of the natural disaster. Stockpiles of essential items and goods must be performed by the local government in order to provide urgent relief to disaster zones. Successful disaster management plans utilize a competent and trained force of volunteers (Wisner, 2004). These volunteers can be instrumental in saving lives and delivering services. Response is the last stage of the disaster management plan as it consists of the provision of emergency and rescue services for people who have been hit by the natural disaster. Conclusion Hurricane Katrina was a natural disaster that severely impacted the people of New Orleans. The poor and slow response by the Bush administration was extensively criticized by the public. The disaster shows the necessity of effective and efficient disaster management programs. These plans must be adequate and competent enough to prevent death and destruction caused by the natural disaster. These programs should effectively utilize a number of rapid emergency and civil services in order to provide relief and aid in the disaster zone. Empirical studies have found evidence that the hierarchical model of organizational change leads to inefficiency and inflexibility. It retards the ability of organizations to effectively respond to emergencies and contingency plans. The network model of organizational change on the other has been found to give autonomy and freedom. This allows staff members to use their creativity and innovation in order to devise solutions for problems. Adaptive management takes a proactive and dynamic approach in resolving problems. It seeks to divide tasks into smaller goals which are distributed to team members. It can be used for disaster management because it efficiently and effectively utilizes and allocates resources. Disaster management must be systematically and methodically planned and arranged by the government. It is essential that reducing or mitigating the threat take place at the first level.

Introduction Of Engine Block

Introduction Of Engine Block Until recently, cast iron and aluminum alloys have been successfully used to manufacture most diesel and conventional gasoline-powered engine blocks. However, with a greater emphasis on increasing the efficiency of the engine via weight reduction, there is a search for alternative alloys that are lighter than cast iron and aluminum alloys, while retaining the necessary strength to withstand the forces of an engine. In the late 1990s engine blocks made from plastic and other experimental materials were being used in prototype cars with the hope of developing more lightweight, efficient vehicles . Also lately new manufacturing processes have been developed that have brought to light two new alloys suitable for use in an engine block, magnesium alloy AMC-SC1 and compacted graphite cast iron (CGI). Thus this project will cover, the functional requirements of the engine block, the processes used to manufacture the part, and the mechanical properties of the alloys. INTRODUCTION: Todays engines are an integral component of an automobile that are built in a number of configurations and are considerably more complex than early automotive engines. The use of lighter and stronger engineering materials to manufacture various components of the engine has also had an impact allowing engineers to increase the power-to-weight of the engine, and thus the automobile. Since the engine block is also a relatively large component, it constitutes 20-25% of the total weight of an engine. Thus there is much interest in reducing the blocks weight.[Keay, Sue: Diet of Australian metal lightens cars and pollution, Media release, 14 October 2002.] Many early engine blocks were manufactured from cast iron alloys primarily due to its high strength and low cost. But, as engine designs became more complicated, the weight of the engine (and thus the vehicle) had increased. Thus the need to come up with lighter alloys that were as strong as cast irons arose. One such material that was being used as a substitute was aluminum alloys. Together, these two metals were used exclusively to fabricate engine blocks. Lately , however, a new material process has made a magnesium alloy suitable for use in engines. The alloy, called AMC-SC1, weighs less than both cast iron and aluminum alloys and represents new possibilities in engine manufacturing. A new manufacturing process have made compacted graphite cast iron (CGI) a viable alternative to gray cast iron for the manufacture of diesel engine blocks. Like magnesium alloys, this material offers a higher strength and lower weight than gray cast iron. Thus this section will cover materials used to manufacture engine blocks , component discussion, its functional requirements, and the materials used to manufacture the part. The mechanical properties of the individual alloys will be incorporated, along with the manufacturing processes used to fabricate the component. DESCRIPTION OF THE PRODUCT: WHAT IS AN ENGINE BLOCK? : The engine block is vital structure of vehicles which run on internal combustion, providing the powerhouse for the vehicle. The engine block is termed a block because it is usually a solid cast, housing the cylinders and their components inside a cooled and lubricated crankcase .Common components found in an engine include pistons, camshafts, timing chains,rocker arms, and other various parts. When fully stripped of all components, the core of the engine can be seen: the cylinder block. The cylinder block (popularly known as the engine block) is the strongest component of an engine that provides much of the housing for the hundreds of parts found in a modern engine. The block is typically arranged in a V, inline, or horizontally-opposed (also referred to as flat) configuration and the number of cylinders range from either 3 to as much as 16. Figure 1 shows engine blocks with V configuation. opposed configurations. Functional Requirements of a Cylinder Block: Because engine blocks are a critical component of an engine, it must satisfy a number of functional requirements. These requirements include withstanding high cycle fatigue stresses, thermal strains, and aggressive wear conditions over the full life of the engine, housing internal moving parts and fluids, ease of service and maintenance. REQUIRED MATERIAL PROPERTIES: The one-dimensional era of engine design is finished. The current approach considers the loads acting at each point of the engine block. (Vollrath, 2003) In order for an engine block to meet the above functional requirements, the engineering material(s) used to manufacture the the cylinder block material should have adequate strength and rigidity in compression, bending, and torsion. This is necessary to resist the gas pressure loads and also for the components, which convert the reciprocating motion of individual piston into a single rotary motion. The cylinder-block material should (a) be relatively cheap, (b) readily produce castings with good impressions, (c) be easily machined, (d) be rigid and strong enough in both bending and torsion, (e) have good abrasion resistance, (f) have good corrosion resistance, (h) have a high thermal conductivity,(to prevent failure under high temperatures). (i) retain its strength at high operating temperatures, and (J) have a relatively high thermal expansion, low density.(to resist expanding under high operating temperatures) High strength is a particular concern in diesel engines, since compression ratios are normally 17.0:1 or higher compared to about 10.0:1 for conventional engines. , and thermal conductivity . Good machinability and castability of the metal alloy are also important factors in selecting the proper material, as the harder it is to machine the product, the higher the costs of manufacturing. In addition to the previously mentioned properties, the alloys must possess good vibration damping to absorb the vibrations of the moving parts. METALS USED IN THE MANUFACTURE OF THE CYLINDER BLOCKS: Based on the functional requirements of the cylinder block and the material properties required to meet the functional requirements, industries have used cast iron and aluminum alloys to manufacture the blocks. EXISTING MATERIALS: 1)Cast iron alloys are used because of the combination of good mechanical properties, low cost, and availability. 2)Certain aluminum alloys combine the characteristics of iron alloys with low weight, thereby making the material more attractive to manufacturers who are seeking a competitive edge. NEW MATERIALS: 3)Compacted graphite cast iron is lighter and stronger than gray cast iron, making the alloy a more attractive alternative to the latter in the production of cylinder blocks, particularly in diesel engines. 4)Magnesium alloys, which were previously unsuited for use as an engine block material, have the advantage of being the lightest of all the mentioned metals, yet still retains the required strength demanded by a block. 1)GRAY CAST IRON ALLOYS: Gray cast iron alloy have been the dominant metal that was used to manufacture conventional gas-powered engine blocks. Though extensive use of aluminum alloys has minimized the popularity of this material, it still finds wide use in diesel-fueled blocks, where the internal stresses are much higher. The use of cast iron blocks has been wide spread due to its low cost and good formability. Generally types of gray cast iron of pearlite microstructure is used in the manufacturing of engine block. Gray cast iron alloys typically composition: A typical cast iron is a gray cast iron, which contains 2.5-4 wt.% carbon, 1-3 wt.% silicon, 0.2-1.0 wt.% manganese, 0.02-0.25 wt.% sulfur, and 0.02-1.0 wt.% phosphorus [Anyalebechi, P.N.: Essentials of Materials Science Engineering, January 2005, p. 94.]. and the balance (93.6%) iron. The carbon improves lubrication property of graphite, the silicon controls the formation of a laminated structure, called pearlite, which has good wear resistance, and the manganese strengthens and toughens the iron structure. A common aluminium alloy composition is 11.5% silicon, 0.5% manganese, and 0.4% magnesium, with the balance (87.6%) aluminium. The high silicon content in this alloy reduces expansion but improves cast-ability, strength, and abrasion resistance, while the other two elements strengthen the aluminium structure. While this alloy provides a good corrosion resistance, it can absorb only moderate shock loads. Types of cast iron used in engine block: SAE grade G2500- used for small engine blocks. SAE grade G3500-used for heavy and larger diesel engine blocks. Also some ductile iron are also used in manufacturing engine blocks. SAE AMS 5313C: mechanical properties: [alloying: understanding the basics , by joseph R devis.] Grade or class Hardness HB(a) Tensile strength min(b) MPa Yield strength min(b) MPa Elongtion in 50 mm(2in),%(b) Class A 190 max 414 310 15 Gray cast iron has excellent damping capacity, good wear and temperature resistance, is easily machinable, and is inexpensive to produce. However, gray cast irons are relatively weak and are prone to fracture and deformation. Although cast iron meets most of these requirements, it has a low thermal conductivity and is comparatively heavier. Due to these limitations, light aluminium alloys have been used as alternative cylinder-block materials for petrol engines. Cylinder liners are optional with cast-iron blocks; but are more essential with the relatively soft light aluminum alloy blocks, as they cannot directly withstand wear resistance. Because of the lower strength of the aluminum alloys, the blocks are cast with thicker sections and additional support ribs, so that their weight becomes about half of the equivalent cast-iron blocks. Due to these problems, compacted graphite iron has recently begun to compete with gray cast iron as the choice material to produce diesel engine blocks. COMPACTED GRAPHITE CAST IRON: Compacted graphite cast iron (CGI), which was accidentally discovered while trying to produce ductile cast iron, possesses higher tensile strength and elastic modulus than gray cast iron due to the compacted graphite found on the microstructure of CGI. Figure 8 CGI typical microstructure: 5% nodularity, 9% graphite, 265 particles/mm2. 3. CGI a new combination of properties: As shown in Fig. 8, the compacted graphite iron graphite particles appear as individual worm-shaped or vermicular particles. The particles are elongated and randomly oriented as in gray iron; however they are shorter and thicker, and have rounded edges. The compacted graphite morphology inhibits crack initiation and growth and is the source of the improved mechanical properties, as compared to gray iron. Compacted graphite iron invariably includes some nodular (spheroidal) graphite particles. As the nodularity increases, the strength and stiffness also increase, but only at the expense of castability and thermal conductivity (Guesser et all, 2001). It is usual to set a limit of 20% nodularity for CGI specifications. Table 1 shows mechanical properties of CGI, with grades from 300 to 500 MPa. In the case of cylinder blocks and heads, where castability, machinability and heat transfer are all of paramount importance, it is necessary to impose a more narrow specification. A typical specification for a CGI cylinder block or head can be summarised as follows: 1) 0-20% nodularity, for optimal castability, machinability and heat transfer 2) No free flake graphite, flake type graphite (as in grey iron) causes local weakness 3) >90% pearlite, to provide high strength and consistent properties 4) This general specification will result in a minimum-measured tensile strength of 450 MPa in a 25 mm diameter test bar, and will satisfy the ISO 16112 Compacted Graphite Iron standard for Grade GJV 450. The typical mechanical properties for this CGI Grade, in comparison to conventional grey cast iron and aluminium are summarised in Table 1: Mechanical and Physical Propertiesof CGI in comparison to conventional grey cast iron and aluminium at 20 °C Property Units GJV 450 GJL 250 GJL 300 A 390.0 Ultimate Tensile Strength MPa 450 250 300 275 Elastic Modulus GPa 145 105 115 80 Elongation % 1 to 2 0 0 1 Rotating-Bending Fatigue 20 °C) MPa 210 110 125 100 Rotating-Bending Fatigue (225 °C) MPa 205 100 120 35 Thermal Conductivity W/m-K 36 46 39 130 Thermal Expansion ÃŽÂ ¼m-m-K 12 12 12 18 Density g/cc 7.1 7.1 7.1 2.7 Brinnell Hardness BHN 10-3000 215-255 190-225 215-225 110-150 The results allow the comparison between CGI and gray iron. It can be seen the increase on tensile strength, moving from gray iron to CGI. CGI also shows a higher elastic modulus, when compared to gray iron. [- Mechanical properties of gray iron and CGI grades 400-450. 195-230 HB. Samples taken from the castings (Guesser, 2003)]. Figure 10 [Elastic modulus of gray iron and CGI grade 400. 12.0L I6 cylinder block (Guesser, 2003).] The results in Figure 10 were obtained from two sources: test bars and main bearings of a 12.0L cylinder block. The increase in elastic modulus, from 100 GPa for gray iron to 150 GPa for CGI, results in slighter cylinder bore distortion as reported by Tholl et all (1996), therefore reducing oil consumption and emissions. Results of fatigue strength tests can be seen on figure 11, comparing gray iron grade 250 and CGI grade 450, samples from an I6 5.9L diesel cylinder block. The fatigue limit for the gray iron is 62-79 MPa, depending on the carbon content, while for the CGI the fatigue limit is 175 MPa. The raise of fatigue strength allows the designer to reduce the cylinder block weight. As a result of mechanical properties improvements, a design study conducted by AVL Austria (Sorger Holland, 1999) has evaluated downsizing opportunities for a 1.8 L diesel engine cylinder block, converting from gray iron to CGI. The benefits of this conversion included: 1)9% reduction in overall weight of the finished engine 2) 22% reduction in weight of machined cylinder block 3) 15% reduction in overall length of the finished engine 4) 5% reduction in both; height and width of the finished engine Like gray cast iron, compacted graphite cast iron has good damping capacity and thermal conductivity, but its difficulty to machine has limited the wide-scale use of CGI. A new manufacturing process, however, has opened the way for larger applications of CGI. The development of rotary insert tools has increased the life of the tools used to machine the metal, thus allowing manufacturers to use CGI without worrying about purchasing new tools [Georgiou, George: Iron engines may be in your future, Tooling Production, September 2003, Vol. 69, issue 9, p. 26.]. MAGNESIUM ALLOYS: Magnesium alloys have been used in engines before, but not for cylinder blocks. Rather. The main advantage of this alloy is that the material is much lighter than cast iron and aluminum alloys and has the same strength as cast iron and aluminum alloys[Lampman, Steven: Tuning Up the Metals in Auto Engines, Advanced Materials Processes, May 1991, p. 17.][Anonymous, Magnesium alloy resists high temperature in engine blocks, Advanced Materials and Processes, August 2003, vol. 161, issue 8, p. 13.]. Material scientists and engineers were determined to exploit these characteristics of magnesium alloy and use it to fabricate engine blocks. There were a number of magnesium alloys available that met or exceeded the requirements demanded by manufacturers for an engine block, but insufficient material stability at high temperatures hindered their actual use. Following are the two alloys which have been found suitable for mass production of engine blocks. AMC-SC1: In 2003 material scientists and engineers from the Cooperative Research Center for Cast Metals Manufacturing and the Australian Magnesium Corporation presented their discovery of sand-cast AMC-SC1 magnesium alloy [Anonymous, Magnesium alloy resists high temperature in engine blocks, Advanced Materials and Processes, August 2003, vol. 161, issue 8, p. 13.]. This grade of magnesium alloy contains two rare earth elements, lanthanum and cerium, and was heat-treated with T6. This stabilizes the strength of the alloy at high engine operating temperatures, which is a necessary requirement for a cylinder block material [16]. Bettles et al. had performed experiments to determine the yield and creep strengths of AMC-SC1 and their results are shown in Table 3 [Bettles, C. et al., AMC-SC1: A New Magnesium Alloy Suitable for Powertrain Applications, Society of Automotive Engineers, 2003, p. 2.]. From Table 3, the most significant point is that the yield strength of AMC-SC1 essentially stays the same at 177 °C as it does at room temperature. Table 3: Yield and creep strengths of magnesium AMC-SC1 at room temperature, 150 °C, and 177 °C [17]. Room temperature 24 °C 150 °C 177 °C Yield strength, MPa 120 116 117 Creep strength, MPa 120 98 This means that the material is able to tolerate a wide range of operating temperatures without a loss in strength. Other properties of the magnesium alloy 10 include good thermal conductivity, excellent machining and casting qualities, and excellent damping characteristics. To demonstrate the significant weight savings of magnesium alloy over cast iron and aluminum alloy, consider BMWs inline-6 R6 (shown in Figure 4), which replaced the companys M54 aluminum engine. Its cylinder block is made of AMC-SC1 and is said to have decreased the weight of a comparably-built gray cast iron and aluminum alloy block by 57% and 24% [Jost, Kevin: BMW builds better inline six, Automotive Engineering International, January 2005, pp. 20-32.]. So far, BMW is the only company to have used magnesium alloy cylinder blocks in production vehicles. But, with a significant weight advantage over the current alloys used today and negligible increase in cost, other manufacturers will begin to consider the use of AMC-SC1 and possibly other grades of magnesium alloys for engine blocks. Figure 4: BMWs 6-cylinder R6 powerplant uses a magnesium alloy AMC-SC1-fabricated cylinder block [Jost, Kevin: BMW builds better inline six, Automotive Engineering International, January 2005, pp. 20-32.]. PRODUCTION PROCESS: STANDARD CASTING WITH SOME MODIFICATIONS: This alloy can be cast using a standard production process, with some modifications. For a magnesium alloy engine to be economically viable, it is not merely the cost of the alloy that is important. The casting process must also be commercially viable. There are several modifications required if an existing casting line of cast iron or aluminum is to be converted to one producing magnesium parts. These can be summarised as follows: à ¢Ã¢â€š ¬Ã‚ ¢ A new inhibitor in the sand cores to prevent reaction between the melt and the sand. à ¢Ã¢â€š ¬Ã‚ ¢ A redesign of the runner and gating system to ensure adequate filling (magnesium alloys have a low heat content). à ¢Ã¢â€š ¬Ã‚ ¢ Preheating of the core package to 150 °C. à ¢Ã¢â€š ¬Ã‚ ¢ Modifications to the core package design to allow low pressure rather than gravity filling and feeding. AM-HP2: AM-HP2 A High Pressure Diecasting Magnesium Alloy: The AM-HP2 magnesium alloy has similar high-temperature strength to AM-SC1 and has been specially tailored for use in the high pressure diecasting process. Like AM-SC1, the light-weight alloy significantly increases fuel-efficiency, environmental sustainability and vehicle agility and is suitable for the powertrain components of vehicles, such as engines blocks etc. Need for New alloy:AM-HP2 AM-HP2 has been specifically developed as a diecasting alloy for high temperature automotive powertrain applications, such as engine blocks, structural sumps and automatic transmission housings. The alloy is based upon the successful sand casting alloy, AM-SC1, with a modified composition to make it suitable for the high pressure die casting process. Commercial Opportunities AM-HP2 Magnesium Alloy in the Auto industry: High pressure diecasting is a highly productive process for mass production of light alloy components. While the casting integrity of sand casting and low pressure/gravity permanent mould castings is higher than high pressure diecasting, the latter technology is cheaper. Thus, this process is gaining popularity among auto manufacturers for casting of aluminium engine blocks. It is also the common process for powertrain components such as transmission housings. There is a strong demand in the automotive industry for a suitable high pressure diecasting magnesium alloy for high volume powertrain applications. AM-HP2 exhibits good diecastability and the required high temperature mechanical properties for engine components (including engine blocks) and automatic transmission housings. It has similar creep properties to alloy, AM-SC1. Advantages of AM-HP2 Magnesium over Other Alloys: A key advantage of AM-HP2 is that the alloy is more diecastable than competitor high temperature creep resistant magnesium alloys.Thus, the alloy can be more readily cast into complex shapes with fewer rejects and a wider operating window. The alloy also has better high temperature creep strength than its competitors and thus offers considerable advantage to engine designers seeking to obtain maximum performance for lowest weight and cost. current status of AM-HP2 magnesium development: Pilot scale diecasting trials and laboratory testing of mechanical properties have demonstrated the suitability of AM-HP2 for mass produced powertrain components. PRODUCTION PROCESSES: 3.2 Casting Processes There are two methods used to cast engine blocks for all materials: green sand molding or lost foam casting. The latter, pioneered by General Motors for their Saturn vehicles, have[11] become more popular due to its capability to produce near net shape components, provide tight tolerances for critical components, and reduce machine maintenance and cost [19]. Green sand molding, however, is still widely used in industry as material costs are low and most metals can be cast by this method [Luther, Norris: Metalcasting and Molding Processes, [Online], 22 March 2005-last visited, Available: http://www.castingsoruce.com/tech_art_metalcasting.asp.]. 3.2.1 Green Sand Molding: Green sand molding the common method to cast engine blocks. The term green denotes the presence of moisture in the molding sand . Figure demonstrates the pattern used in sand casting. The pattern mounted into the moulding box along with the runner and ingate system ready to produce a mould. [http://www.dmdaustralia.com.au/block1.html] From Figure 2, a combination of silica sand, clay, and water poured in one-half of the block pattern with a wood or metal frame. The mold is then compacted by squeezing or jolting, and the process is repeated for the other half of the mold. A core consisting of hardened sand is used for support. Then, molten cast iron, aluminum, or magnesium alloy is poured into the combined molds and solidifies. Once the latter part has been completed, the molds are removed, and the cylinder block is cleaned and inspected. Heat treatment of the block is then undertaken to improve the mechanical properties of the alloy for suitable use. [7]. 12 LOST FOAM CASTING: THE PROCESS: Figure 6: Graphical description of the last 6 of 7 methods of the lost foam casting method [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.] The lost foam casting process uses a expanded polystyrene replica of the part being cast. 1)The coated replica/pattern is placed in a flask and loose sand is placed around the pattern and shaken into its voids. 2)Molten metal is then poured through a foam sprue, or funnel, into the sand where the hot metal melts and displaces the foam of the pattern. 3)the metal cools in the shape of the part. The basic steps of the lost foam casting process are: 1) Pattern Molding Bead Pre expansion and Conditioning, Tool Preheat, Pattern Molding, Pattern Aging 2)Pattern/Cluster Assembly 3)Pattern Coating and Drying 4)Sand Fill and Compaction Metal Casting and Cooling 5)Shakeout, Clean-up, and Finishing Lost foam casting is a more reliable and efficient casting technique of the manufacture of engine blocks than green sand molding. The technique begins with the use of polystyrene beads placed in preexpanders for wet expansion to control bead size and density to produce four separate block moldings to be glued together to form the final mold [7, 19]. Next, the metal tool is preheated to remove any moisture and then filled with the beads. The tool is then heated via steam and placed in an autoclave, where it is subjected to high pressures in order to create the molds [7]. The tool is removed from the autoclave and immersed in water to finish the moldings. Precise control over the heating and cooling aspect ensures dimensionally accurate, smooth and strong molds [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.]. If the tool was not heated before the beads were injected, the results would be rough finishes in the molds with low-strength sections. If the tool and beads stay heated for an extended period of time, or is not cooled enough, the beads become overfused, which produces surface variations in the moldings. If the tool has been inadequately cooled, the molds will contain variations in dimensions [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.]. Figure 3 shows the final half stages of the lost foam casting method. . From Figure 3, once the individual molds are glued together, the assembly is placed in a vat with water-based ceramic liquid to prevent molten metal from destroying the mold, stiffen the assembly, and provide a smooth finish [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.]. The assembly can also be sprayed with the ceramic liquid, but is a time-consuming process. Next, the coated foam engine block is filled with sand,[13] compacted, and immersed in the molten metal alloy. Once cooled, sand is removed from the metal casting, cleaned, and undergoes heat treatment to increase the mechanical properties of the block. Finally, coolant and oil passages are machined into the block. Advantages over conventional sand casting: Unlike conventional sand casting, the lost foam process allows more complex and detailed passages and other features to be cast directly into the part. The lost foam process: 1) Forms complex internal passages and features without cores. 2) Reduces part mass with near net shape capability. 3) Eliminates parting lines. 4) Reduces machining operations and costs. 5)Provides for tight tolerances in critical areas and features. Lost Foam Casting for Fine Features: The lost foam casting process allows more complex and detailed passages and other features to be cast directly into the cylinder block. 1) In the cylinder block, oil galleries, crank case ventilation channels, oil drain back passages, and coolant passages are cast into the block. 2) These features would otherwise require drilling or external plumbing (with a potential for leaks). 3)Lost Foam castings have tighter dimensional tolerances compared to sand castings, because variations caused by core shift and core variability are eliminated and there is much less tool wear over the production life. The direct result is a significant reduction in machining costs and infrastructure investment and fewer opportunities for errors in machining and assembly. A comparison of green sand casting to lost foam casting shows a number of distinct advantages for lost foam: Property Green Sand Casting Lost Foam Casting Complex Internal Features and Part Consolidation Complexity determined by sand core limitations geometry, strength, and cost. Extensive and complex internal features (as small as 0.20) available in lost foam, based on detail duplication and pattern assembly in foam. Dimensional Tolerances +/- 0.030 is typical depending on part size, complexity, and geometry +/- 0.005-0.010 is typical depending on part size, complexity, and geometry. Surface Finish Capabilities 250-600 microinches typical. Depends on grain fineness of sand. 60-250 microinches typical. Depends on bead size and ceramic coating grain fineness. Feature Accuracy Core movement and shift between mold halves across the parting line limit feature accuracy. No cores or mold halves to shift and degrade feature accuracy Parting Line and Draft Angles Parting lines and draft angles are necessary for molding. No parting lines in the mold and minimal draft on tools. Environmental Costs Sand recovery requires binder removal and time consuming sand clean-up Sand is binder free, so it can be easily and rapidly recovered a

People running around with underwear on their head, a fake suicide over the Niagara Falls, forest rangers who are positive they seen Bigfoot, and sheriffs who make x-rated videos on a rented video camera and forget to take the tape out. These are some of the wacky stories Krista Bradford experiences during her career as an anchor on tabloid television. She tries to convince the reader that TV tabloids are trashy in the article â€Å"The Big Sleaze published in Rolling Stone magazine in 1993.   Ã‚  Ã‚  Ã‚  Ã‚  Bradford writes the article in a unique fashion. She writes it as a story. Everything in the article is an experience, which make this article more interesting and convincing. Her first an anchor job was at the age of 18, she was an intern for Joan Lunden at KCRA-TV in Sacramento, California. She lost that job 10 years later so she met with Peter Brennan, the producer of A Current Affair, and he gave Bradford a job as an anchor. 6 months later they wanted her to portray a bimbo rape victim in a reenactment. She refused and went on with her life. After she was done at A Current Affair, she worked at The Reporters. She ended her career with a show hosted by Geraldo Rivera named Now It Can Be Told. She worked in tabloid TV for five years and has a lot of experience with it and that helps to make this article convincing.   Ã‚  Ã‚  Ã‚  Ã‚   Bradford is very negative towards television tabloids. Her tone towards everything in the article is strong and negative. She uses profane and Informal language, like tits-and-ass raunchiness and rubbernecking at the oddities of American life. Her language has a lot of trashiness to it. She also says TV tabloids do not mature the mind, they mutate it. In the article, Bradford doesn’t make the mistake on using too big of words. She uses words that everyone can understand, not just her colleagues. For instance, she uses the word â€Å"bigwigs,† basically everyone knows what that word means. She also uses the phrase â€Å"Joe six-pack.† A lot of what has to do with articles are the race of a person their attractive ness and their sexual orientation. The truth is TV tabloids discriminate against people of different race, gays, and unattractive women. They also use racial slurs and that will upset a lot of people. These are some of the negative points she uses against tabloid television.

why everyone should own 1 punk cd Essay -- essays research papers

Outline for Persuasive Speech Topic: Why everyone should own one Punk CD. 1. a. By a show of hands I would like to see how many of you listen to Punk Rock. Today I’d like to talk to you about this genre of music that was created in reaction to other forms of music, and hopefully influence you to check it out and maybe even buy a CD. i. I’ve been listening to punk since as early as the 5th grade. â€Å"Punk† (make quote sign) is a term applied to a child or teenager who acts in an antisocial way. Punk music is a form of rebellion, and it turned against all other musical forms and influences at its time of creation. Punk music is as much cultural as it is musical. It is anarchic, against society, and against everything in established order. ii. I’d like to give you a brief history, the philosophy behind the music, and how what you hear today on the radio isn’t quite the same. I’ve included a few of the bands that I like to give you an idea what I’m talking about. Punk rock is much more than just music as music is just expressions of what people hold dear to them. Transition statement: But since I don’t have all day to talk lets go to a brief history. A LITTLE BIT OF HISTORY Most of the first wave of British punk were born from art schools. Members from The Clash, Sex pistols, Damned, Wire, Adam and the ants, and Siouxsie and the Banshees had all come from such places in and around London. A large contingent came from in and around the Kings road area of west London, and a lot of the first wave knew of each other first hand- Tony James (Gen X), Mick Jones (Clash). Topper Headen (Clash) and Keith Levine (Clash, Public Image) had all been in the London SS, a Proto-punk band featuring the aforementioned all-star line-up. Shortly after The SS split, Tony James went to form Chelsea with future Generation X member and MTV pop star Billy Idol. In addition they recruited future Damned Guitarist and leader Brian James. The Clash's Leader, Joe Strummer had been plying his trade in the pub rock scene, which was instrumental to the rise of punk, with his previous band the 101'ers. As soon as he saw the Pistols, he knew his band was outdated. Strummer was actually an ex public schoolboy, and his dad was a worker in the national treasury of some sort. Other bands, such as the UK subs had also evolved from pub rock- Charlie Harper was in the marauders prior to forming the sub... ...e people its all about who out punk or be more hardcore than the next punk. People who disregard other punks for the type of punk they listen to. The most disregarded punks are the ones who listen to some commercialized music. This in general to me is ok to a certain degree. If you love the music and it means something to you it is ok with me, but if you are just listening to it because other people do or you are just radio oriented for any band I dislike it. Punks shouldn't deem those who listen to some commercial music and love it posers. That is wrong to me. Everyone knows that for how many punks there are in an area there are usually just as many posers. The people who I think qualify as posers are radio oriented, do things or listen to a band just because other true punks are and have no love for it, people who just do it for the style, and people with a punk attitude with no beliefs to back it up. You will never see a person listening to rap or techno listening to punk musi c, but as a punk, we are taught to be more open to different styles of music, because punk is not a contest, it is unity, love for the music, an attitude, a lifestyle, and many other things to be true to.

The Cattle Industrys Effect on our Environment Essay -- Beef Environ

The Cattle Industry's Effect on our Environment Before I began my research, I avoided beef for health reasons. During my junior year of high school, I reformed my diet away from my family’s very beef-laden diet into a more heart-healthy, Mediterranean-style one. My great grandfather started a revolutionary meat company in San Francisco, CA which later moved to Marysville, CA called DPM. Most of my family, including my father, worked in this company and its butcher shop for many years before it was eventually sold to an international corporation. Needless to say, my extended family has a strong love and passion for quality meat and cooking it is a large part of our frequent family get-togethers. I must continually defend my choice to not eat beef, and even though it has been many years since I first made this decision, many of them often seem to â€Å"forget† when choosing a menu. Since I stopped eating beef, I have been more interested in other related issues, such as the hormones and antibiotics we give our ca ttle, as well as the link to this nation’s huge obesity problem. I met a friend while I was living in Italy named Caitlyn who did not eat meat, primarily because of the impact it was having on agriculture, and the methods used in producing it. She told me briefly of her reasons, but never went into explicit detail with me; ever since then I have had a lingering curiosity to do my own research and come to my own conclusions. When I first began my research, I knew of many of the issues with antibiotics and hormones that we give our cattle, and did not agree with them. As biology major, I have learned about this trend in school. Antibiotic resistance is a huge problem; there are already many infections that whil... ...tions of nutrients in many of the crops. Organic farming today is closer to the way farming was in the days of old, with locally-minded people concerned with their community’s health and sustainability.

Psychology Reflective Paper Essay

This class has not only enabled me to become a better student, but also a more productive adult in various ways. Initially, I came into your class ecstatic because I knew the journey I would embark would be an exciting one; however, I encountered challenges throughout the course although learning new psychological methods is enthusing to me. I learned about the origin of psychology and the evolution of modern psychology. In further detail, I will discuss how the learning goals of this course have influenced my career and personal life. When I began college, I was undecided about what to study. Initially, I enrolled as Biology major. I majored in biology for three years of my college career. Because I was not happy or even satisfied, I decided to pursue studying a subject that genuinely grasped my interest. I knew in my heart that whatever I was searching for had to be something I would love doing for the rest of my life or at least most of it. Therefore, I went on an exploration to find that one particular area of study that would be of great significance to me and my future endeavors. I came across Psychology. I didn’t know much about it. All I knew was that I took it during my freshman year because it was a requirement to take Psychology 101. The entire time while I was reminiscing about this class, all I could remember was the professor lecturing about the human mind and why people do what they do. I found it to be sort of interesting and I said, â€Å"Hey, why not give it a try?† Previously, I had skeptic views. I contemplated about making this big change because I thought there was nothing else left for me to do but to†¦ â€Å"Just do it!† Because I am new to everything that is going on around me within my Psychology courses, there is plenty that I wish to obtain and learn: not just from my professors but also from my peers. One class that I have taken is History and Systems of Psychology, and it is one of my most interesting Psychology courses here at the University. This course is very different from many classes that I have taken. There are seminars, blogs, essays, Greeks, and much more that surround this course. The seminars consist of in class discussions where we converse about different readings and how we feel about what was read, as well as what the writer was trying to convey to his or her audience. Sometimes the discussions can become intense but it is stimulating. I am not much of a public speaker, but the seminars are beneficial to me conquering my phobia of speaking in front of a crowd of people. The course is informative but surprisingly it isn’t boring. I perceive as motivation to do well through the learning goals that are set out before us by the professor. Contrary, to my previous study of Psychology, I have learned a vast amount of information from being in this course. Yes, History and Systems of Psychology will inform and teach me about the ancient Greeks and their attributes towards the development of Psychology but I will also learn skills that will definitely be beneficial in my career as a Speech Pathologist. A Speech Pathologist evaluates and diagnosis speech, language, cognitive- communication and swallowing disorders. They also treat speech, language, cognitive- communication and swallowing disorders in individuals of all ages, from infants to the elderly. The class is not only lecturing, but also growth for future purposes. My fellow classmates and I will be able to network with one another on a more intellectual level. We are all able to discuss our opinions about different topics through seminars. This is a way to help better our communication and listening skills. Patience is gained when waiting for others to speak, even though you may be eager to express your views on a particular situation. It helps us to be more open-minded to others’ opinions which provide us with the opportunity to learn from one another and just the professor. Because it is proven that the focus of psychological studies in modern society may not reflect its colorful and amusing history, its roots however fluctuate from the modern philosophies of the field. In order to totally comprehend psychology, one must first go back into its history and explore its origins. A question that I asked myself and became informed of throughout the course of this semester is: â€Å"How did the studies of Psychology originate? What period was Psychology created?† Because I was able to question myself, I became more involved and interesting not only in Psychology 445, but the overall studies of Psychology. As I answered these questions, I realized that Psychology involves a massive range of topics; alongside, examining the human’s developmental patterns and mental practices from cultural level to neural level. Interestingly, I learned that Speech Pathologists study the same materials as Psychologists. For example, both patricians must know matters pertaining to human mental concerns. These issues can begin right from delivery and endure up until the death of the person. Through the knowledge developed in Psychology 445, I will be able to better comprehend how the individual topics are studied and what has been taught thus far. One of my most beloved and studied psychologist has been Sigmund Freud (Freud). Independently, I studied Freud; the famous Austrian physician transformed the entire face of psychology in such an intense way by creating a theory of personality that strained on the significance of the unconscious mind. Freud’s involvement with clients anguish from mental ailments like hysteria directed him to consider that one’s early childhood encounters as well as our unconscious impulses contribute greatly towards the development of our adult lifestyle behavior and characteristics. You may ask yourself: â€Å"Why is this information important to?† As stated in our learning goals there are many historical psychologists who can give an account for the evolution of modern psychology. It is important for me to understand the history and previous studies because past determinations will enable me to diagnose my clients when I work as a speech pathologist. There are commonalties between psychologist and speech pathologist. Because of these similarities, I have encountered psychological skills that I plan to utilize as a speech pathologist. Interestingly, Psychology continues to evolve! Currently, majority practices do not identify themselves with a distinct school of thought. Instead, workers prefer focusing on certain specialty ranges or perspectives, often creating conclusions from a wide range of theoretical experiences. This methodology has contributed new theories and ideas that still carry on to shape the future of psychology. In conclusion, I learned quality listening and observance skills. In order for me to be a good Speech Pathologist, I must be able to listen and communicate with the patients. I must be patient, stable, tolerant of others, confident, and the ability to communicate effectively, both orally and in writing. Surprisingly, in class being emotionally stable really is a great trait to have and learn. Because everyone does not have identical in personalities and background life experiences, everyone may not think alike. In most cases, when there is a discussion and there are many different thoughts and opinions being tossed in the air, some individuals tend to become a little upset because they may feel that what they believe is correct. However, when engaging in conversation with others who may have different point of views, there is no right or wrong. Therefore, having emotional stability is important. I believe that this change which I have made is for the best. I feel that with every moment I attend class, I am discovering something new and opening myself up to bigger and brighter opportunities.

Maslow's Theory of Needs and Leadership - Essay Example The implementation of CSR in an organization can be integrated with Maslow’s theory of motivation through the employees. Employees have a need to be recognized in the organization, which is a major part of Maslow’s theory of motivation. The achievement of CSR in an organization is achieved through a trade-off between the social responsibility and financial impacts of the program, which can be achieved by the provision of motivation to the employees. The second article, â€Å"Learn Change Leadership from Two Great Teachers† (Maccoby), discusses the systems that can be used in an organization to make it more effective and efficient. The author cites the examples of two historical figures that helped in the development of systems to motivate employees.

Ethics exam - Essay Example n technology today have been beneficial, but it has also held its disadvantages as well as such advances have been made by the use of establishments such as factories and processing plants which have also been responsible for playing a large role in the pollution of the environment. To right this wrong the society cannot depend on the government alone as this will be too big a task to be handled by one institution and thus they will require the cooperation and help of every individual involved. It should be noted that one cannot easily thrive in a harsh environment and thus it can be said that the progress and achievement that has been realized by the society has been due partly to the environment and resources that it has had to offer. Knowing this it would not be right for the human population to then turn around and continue to indulge in activities that they are aware are affecting the environment in a negative manner. As a means of showing our appreciation, it should be every individual’s responsibility to take it upon themselves to play a part in cleaning up the environment no matter how small a role one might perceive it to be (De La Torre, 2004). Knowing that the environment is being destroyed and doing nothing about it equates to destroying the environment and thus it should be noted that one should not consider themselves innocent just because they are not involved in the pollution activities that are happening around them. The environment was also given to the human race by the Lord, and while doing so he put us in charge of its care and thus it is our responsibility. Just as one would not sit back and watch their child die we should not be unmoved by the plight of the environment (Pope Leo, 1890). Taking care of the environment will benefit every individual in the after all so the task should not be taken up by a few people, but by every single person present in the world. The alternatives at our disposal, as opposed to taking care of the

International Business Management Essay Example | Topics and Well Written Essays - 3000 words - 2

International Business Management - Essay Example It would use it to provide insight into how the concept can be used and a critical example of how the theory can be invoked. In his book, Competitive Strategy, Porter identifies some important elements that are necessary for the attainment of competitive advantage. Porter stated that competitive advantage arises when a firm provides the highest level of value to consumers, and hence attract the highest prices from them. Porter argues that this can only be internalised if a firm identifies some external elements in the business environment and internalize them in order to form a strategy based on them. In order to attain competitive advantage, a business needs to examine the unique positions and capabilities of competitors and players in an industry. When this is done, a firm can identify a business strategy and after that, designs its functional systems. Industry analysis involves the examination of the key players and the key threats to a given firms quest to attain competitive advantage. This is done by examining five main forces of the industry. These elements are: Every industry exists to produce some kind of value to the wider society. The industry would always exist and there is some kind of balance and stability that comes up naturally as the industry thrives and grows. The risk of entry of potential competitors refers to the situation whereby some third party businesses can enter the industry and produce services that can change the dynamics. The risk of potential competitors entering a given industry is strongly related to the presence or absence of barriers in a given industry. If there are no barriers in the industry and new entrants can easily enter, and this would make the sector extremely problematic. This is because a firms competitive advantage can be easily threatened. However, if there are high barriers like high capital requirement and other regulations, then an
