Lockheed Martin Essay Question: By laying of Lockheed Martin employees, does it affect the future sales of the company? Articles: Lockheed Martin Not Giving Layoff Notices, At White House Request, Lockheed Martin Drops Plan to Issue Layoff Notices, and Lockheed Martin threatens big cuts I. Introduction The Lockheed Martin Corporation ousted its incoming chief executive, Christopher Kubasik, for having a close relationship with a subordinate at the defense contractor. They forced him to resign after the investigation found it to be improper conduct, which violated Lockheed Martin’s code of ethics. However, Mr. Kubasik felt that his affair did not interfere in any way with his job performance. There have recently been some budget cuts at the Pentagon, and contractors are trying to adjust to the changes. The Lockheed Martin directors favored promoting Ms. Hewson, a contractor; because they believe she performs well in other management roles. She had been with Lockheed since 1983, and will immediately become president and chief operating officer of the corporation. II. Findings A. Layoffs (finding 1) 1. Pending job cuts 2. Warnings (the WARN Act) 3. Less pay B. Budget cuts (finding 2) 1. Reduction in Pentagon spending ($500 billion) 2. Minimized the potential for waste and disruption associated with the issuance of unwarned layoff notices. 3. Less spending C. Smaller workforce 1. 18% smaller 2. Hiring pace is slower 3. Fewer jobs available = smaller workforce III. Analysis A. Stakeholder analysis B. Cost-benefit analysis C. Six thinking hat IV. Conclusion Based on the findings and analysis, by laying off Lockheed Marin employees, it would affect the corporation and future sales negatively. Since there will be mass job cuts, the company will slowly start to deteriorate and will fall apart altogether.

Child Abuse: Long term harms

Child Abuse: Long term harms Parents today dont realize that the harm that they are doing to their children will eventually be passed down from generation to generation; their children are todays abused tomorrows abusers. Obviously, parents or guardians will not understand the impact that is caused to their child until they acknowledging there childs choice in life style. In particular, child abuse is a mistreatment of a child by a parent or guardian, including neglect, beating, and, sexual molestation (Salus). Child abuse has an enormous impact among many families globally because child abuse is a detrimental aspect of a childs life as well as the developmental stages in a childs life, which would cause them to have physical, psychological, or behavioral consequences as they grow. Therefore, the maltreatment and neglect in child abuse is a causative factor in youth suicide, crime, homeless, mental illness, drug and alcohol abuse as well as unemployment in a victims life span (info,†¦.). In particular, there are parents, guardians and even caregivers that would imply that an injury resulting from abuse is accidental because they did not intended to hurt the child. For example, some guardians that discipline there children could be abusing them psychologically or even physically (Asseal). Additionally, people would think that the way they discipline a child is perfectly fine because they want them to learn how to do it the proper way (Bissel). The parental or guardian will always try to make the right choice which would be either to let it go or punish the child. To summarize, people will never know how much the discipline or punishment can lead to in the long run. My expository thesis statement is child abuse is an enormous problem among many families globally because child abuse is a detrimental aspect of a childs life as well as the developmental stages in a childs life, which would cause them to have physical, psychological, or behavioral consequences as they grow . Indeed, many people say that child abuse should be legal because an injury resulting from physical abuse is not accidental the parent or caregiver may not have intended to hurt the child. However, child abuse shouldnt be legalize under any certain circumstance because children can end up with physical, psychological or even behavioral consequences. Initially, child abuse should not be legalized under any circumstance because as children get older they can generate a physical consequence. It is stated that physical abuse is among of the top three largest types of child abuse that affect the children globally. For instance, during 2003 18.9 percent of children were physically abused (Services,†¦). Likewise, more than one-quarter of children who had been in foster care for longer than 12 months had some lasting or recurring health problem (Bissell). As a result it has been shown, in some cases, to cause important regions of the brain to fail to form or grow properly, resulting in impaired development (Bissell). In some cases the physical effects are temporary; however, the pain and suffering they cause a child should not be discounted (Families,..). The immediate physical effects of abuse can be relatively minor like bruises or cuts or severe where there are broken bones, hemorrhage, or even death (Bissell). If this type of a buse can be prevented it should be prevented because every day three out of ten children die. Studies also state that child abuse would affect a childs young development and are prone to physical consequences. Whereas, if the child have extremely abusive guardians the child will tends to end up with physical consequences. In summation, if children have physical consequence due the child abuse, we dont we do more to prevent it? Next child abuse has different consequences such as psychological which affect a childs development mentally. Furthermore, research shows that children that are abuse will have one of the psychological consequences. About 80% of 21 year olds that were abused as children met criteria for at least one psychological consequence (Salus). To illustrate, as many as 80 percent of young adults who had been abused met the diagnostic criteria for at least one psychiatric disorder at age 21 (Salus). In addition, these young adults exhibited many problems, including anxiety, eating disorders, suicide attempts, and posttraumatic stress disorder (service, †¦). The immediate emotional effects of abuse and neglect isolation, fear, and an inability to trust can translate into lifelong consequences, including low self-esteem, depression, and relationship difficulties (Salus). Depression and withdrawal symptoms were common among children as young as 3 who experienced emotional, physical, or enviro nmental neglect (information,†¦). Due to abuse the child can have a dramatic impact on a child when they are young which means as they get older they can develop a psychological consequence. Obviously, children who experience rejection or neglect are more likely to develop antisocial traits as they grow up (PerantalRights.org). Children that have a psychological consequence due to child abuse have problems opening up to people. As a result, of child abuse that leads to psychological consequences is this research worth the cost? For children globally, that have been abused will have behavioral consequences as they grow older. In other words, they will not know how to control the life nor the choices they are making along the way. Due to the abusers, in the long run children that have been abused will more likely appear to have behavioral consequences at a young age and as they get older. Consequently, children who experience child abuse and neglect are 59 percent more likely to be arrested as a juvenile, 28 percent more likely to be arrested as an adult, and 30 percent more likely to commit violent crime (Bissell). In particular, studies have shown that abused and neglected children are at least 25 percent more likely to experience problems such as delinquency, teen pregnancy, low academic achievement, drug use, and mental health problems (Dawkins). Similarly, the possible consequence of child abuse can vary on the circumstance of the childs form of abuse (Familie,†¦). According to a National Institute of Justice study, abused and neglected children were 11 times more likely to be arrested for criminal behavior as a juvenile and 3.1 times more likely to be arrested for one of many forms of violent crime (Asseal). Research consistently reflects an increased likelihood that abused and neglected children will smoke cigarettes, abuse alcohol, or take illicit drugs during their lifetime (Claims†¦). Even though people dont think that a behavioral consequence is possible due to child abuse it is and it will affect the child in a young stage of their life. Therefore, child abuse should be controlled so that children do not have to go through all these ups and down with all their wrong choices. In conclusion, child abuse shouldnt be legalized under any certain circumstance for the reason that children can end up with physical, psychological or even behavioral consequences. Furthermore, child abuse has a great contribution in many families globally, as a result of child abuse which is be a detrimental aspect in a childs life as well as in their developmental stages. Since, child abuse occurs at every socioeconomic level, across ethnic and cultural lines, within all religions and at all levels of education. Taking one simple action and reporting child abuse will help prevent a child from being abuse. As well as giving those whom have been abused hope for a brighter future. However, child abuse does not go away, but 90 percent of those who are abused are preventable. For instance, if a parent would stop and just think for a minute about the consequences that may occur to the child in the long run, they would not think of abusing the child. Therefore, there would be just one le ss child being abused.

The Three Types Of Impulse Turbine Engineering Essay

The Three Types Of Impulse Turbine Engineering Essay A turbine is a rotary engine that extracts energy from a fluid or air flow. The simplest turbines have one moving part, a rotor assembly, which is a shaft with blades where the moving fluid acts on the blades, or the blades react to the flow, so that they rotate and impart energy to the rotor. Examples of early turbines are windmills and water wheels. Turbines usually have a casing around the blades that contains and controls the working fluid. Working fluid contains kinetic energy (velocity head) and potential energy (pressure head) and these working fluids may be compressible or incompressible. A compressor or pump is a device similar to a turbine but operating in reverse. The turbines produce almost all electric power on Earth. Most jet engines rely on turbines to supply mechanical work from their working fluid and fuel as do all nuclear ships and power plants. Aircraft engines also use the turbine powered by their exhaust to drive an intake-air compressor, a configuration known as a turbocharger (turbine supercharger). Turbines could also be used as powering system for a remote controlled plane that creates thrust and lifts the plane of the ground. They are as small as soda can, yet still strong enough to move objects with a weight of 100kg. THE TURBINE PROCESS If high-velocity steam is blown on to a curved blade and the steam direction changes as it passes across the blade. The steam will impart a force to the blade as a result of its change in direction across the blade. Now if the blades were free, it would move off in the direction of the force. The principle of steam turbine is where a number of blades were fixed around the circumference of a disc and the disc is free to rotate on a shaft. Steam is then blown across the blades which cause the disc rotates. To increase the rigidity of the blades, the top of the blades are connected together. By means of the nozzles, the high pressure steam is made to give up some of its energy to produce a large increase in kinetic energy of the steam. The steam thus leaves the nozzles at a high velocity. It passes from the nozzles over the blades and thus the turbine disc rotates. The power is then generated at the shaft. The number of nozzles which are in use act as a load to the turbine and so the hi gher the load requires that more steam must be used to sustain the load. Therefore, more nozzles are put into the used. The turbine described is a simple turbine which is also known as de Laval turbine. This type of turbine usually rotates at a very high speed and this high speed will produce a centrifugal force. This turbine is usually small in size and, hence produces small power output. Due to the high speed of rotation, a direct drive between drive between the turbine disc and external equipment is not generally possible. For this reason, a reduction gear box is installed between and turbines of the turbine disc and external equipment. A problem in steam turbine development has been to reduce the speed of rotation and at the same time to make full use of the energy in the steam, thus larger size and higher power output is produce. There are two basic types of turbines which is the impulse turbine and the reaction turbine. THE IMPULSE TURBINES These turbines change the direction of flow of a high velocity fluid jet and the resulting impulse spins the turbine and leaves the fluid flow with diminished kinetic energy. The pressure in the fluid of the turbine rotor blades remains constant. Before reaching the turbine the fluids pressure head is changed to velocity head by accelerating the fluid with a nozzle. Impulse turbines do not require a pressure casement around the runner since the fluid jet is prepared by a nozzle prior to reaching turbine. The transfer of energy for impulse turbines uses the Newtons second law. There are three different types of impulse turbines which are the Velocity compounding turbine Pressure compounding turbine Pressure-velocity compounding turbine THE REACTION TURBINES These turbines develop torque by reacting to the fluids pressure or weight. The pressure of the fluid changes as it passes through the turbine rotor blades. The reaction turbines require a pressure casement to contain the working fluid as it acts on the turbine stage or the turbine must be fully immersed in the fluid flow (wind turbines). The casing contains and directs the working fluid and, for water turbines, maintains the suction imparted by the draft tube. Multiple turbine stages may be used to harness the expanding gas efficiently for compressible working fluids. The transfer of energy in the reaction turbine uses the Newtons third law. Purple Moving blades Blue Velocity Red Pressure Brown Fixed blades THE VELOCITY COMPOUNDING TURBINE IN IMPULSE TURBINES Steam is expanded in a single row or nozzles in this type of turbine. The high velocity steam leaving the nozzles passes on the first row of the moving blades where its velocity is only partially reduced. Then, the steam leaving the first row of moving blades passes into a row of fixed blades mounted in the turbine casing and this row of fixed blades serves to redirect the steam back to the direction of motion such that it is suitable for entry to the second row of moving blades. The steam velocity reduces partially in the second row of the moving blades. A slower turbine is resulted due to only part of the velocity of the steam is used up in each row of the blades. Blue Velocity Red Pressure Green Nozzle Purple Moving blades THE PRESSURE COMPOUNDING TURBINE IN IMPULSE TURBINES The steam enters a row of nozzles where its pressure is only partially reduced and its velocity is increased in this type of turbine. The high velocity steam passes to a row of moving blades where its velocity is reduced. The pressure is again partially reduced and its velocity is again increased when the steam passes into a second row of nozzles. The high velocity steam is then passed to a second row of moving blades where its velocity is again reduced. Next, the steam then passes into a third row of nozzles and so on. All pressure drops occur in the nozzles but the pressure remain constant in each turbine stage. The turbine run slower since steam velocities will not be so high due to only part of the pressure drop occurs in each stage. All stages, however, are coupled to the same shaft, with the result that there is no loss of output. Green Nozzle Purple Moving blades THE PRESSURE-VELOCITY COMPOUNDING TURBINE IN IMPULSE TURBINE A combination of the pressure compounding turbine and the velocity compounding turbine will give a pressure-velocity compounding turbine. In this type of turbine, the steam is partially expanded in a row of nozzles where its velocity is increased. The steam then enters a few rows of velocity compounding turbine and then to a second row of nozzles where its velocity increases. The steam then enters another few rows of velocity compounding turbine and so on. All the pressure at the nozzles decreases. Generally, the diameter from the inlet to the exhaust increases in all multistage turbines. This is because the specific volume increases as the pressure of steam falls. A greater area will be required to pass the steam for continuity of mass flow and this can be done by either increasing the diameter of the turbine discs or increasing the height of the blades. A greater area will be required to pass the steam in order to preserve the mass flow if there is depreciation in velocity. Blue Velocity Red Pressure Green Nozzle Brown Fixed blades Purple Moving blades DIFFERENCES OF THE TURBINES There are many differences that can be stated between the 3 types of impulse turbine. The 3 types of impulse turbine are the: Velocity compounding Pressure compounding Pressure-velocity compounding The differences between these turbines can be classified in terms of: Structure of the turbine The process of the turbine The pressure change in the turbine The velocity change in the turbine Structure of the turbine The structure of the velocity compounding turbine is it consists of a turbine then to a moving blade and a fixed blade. The structure then continues with a second row of moving and fixed blades. The structure of the pressure compounding turbine is it starts from a turbine and then to a moving blade then to a second row of turbine and moving blades and so on. Besides that, the structure of the pressure-velocity compounding turbine is the combine of both of the structure of the velocity compounding turbine and pressure compounding turbine. The process of the turbines High velocity steam from the nozzles passes thru the moving blades then to the fixed blade and the second row of moving and fixed blade in the velocity compounding turbine. In the pressure velocity turbine, the high velocity steam from the nozzles passes thru a moving blades and the low velocity of steam enters another turbine and then to a second row of moving blades and so on. Whereas in the pressure-velocity compounding turbine, the steam from the turbine enters a row of moving blades then a fixed blade and then another row of moving blades. The steam finally then enters another turbine and the process is repeated. The pressure change in the turbine The pressure in the velocity compounding turbine remains constant throughout. In the pressure compounding turbine, the pressure decreases partially when it passes the rows of turbine. Furthermore, the pressure in the pressure-velocity compounding decreases partially then it passes thru the row or turbine and remains constant until the second row of turbine where the pressure decreases partially again. The velocity in the turbine The steam velocity reduces partially in the rows of the moving blades in the velocity compounding turbine. A slower turbine is resulted due to only part of the velocity of the steam is used up in each row of the blades. Whereas in the pressure compounding, the velocity decreases partially when its pass thru the blades but increases back when passing the nozzles. Finally, in the pressure-velocity compounding turbine, the velocity decreases in the turbine and remains constant when passing the blades. The velocity is again decreased when passes thru a second row of turbine. CONCLUSION The steam turbine has greatly improved the energy conversation in our daily lives. There are still future developments oh the steam turbines in order to improve efficiency. Development are now developing turbine which requires a smaller input but produces a bigger output.

Bless Me, Ultima Essay -- essays research papers

Antonio is Alienated   Ã‚  Ã‚  Ã‚  Ã‚  I believe that in the novel Bless Me, Ultima Antonio is an alienated individual. He doesn’t seem to act like any of the other kids his age and has been through so much more then they have. For example, Antonio is torn between making his mother happy and becoming a priest, or making his father happy and becoming a cowboy type figure. He also has experienced a lot of death in his life to people he cared deeply about. I believe that Antonio is alienated because he has the mind of an adult, he is the only one who can talk to Ultima, and he can see the future. Oddly, Antonio is the only one who understands Ultima. For example, in the beginning of the book Antonio shook Ultima’s hand and he could sense the power of a whirlwind pass through hi...

The Old Man And The Sea :: essays research papers

This book takes place in the past and is about an old man that loves fishing in the Gulf Stream. The old man was a thin with deep wrinkles in the back of his neck and had scars on his hands from handling the fishing rope. He taught this young boy how to fish and the boy loved him. He even brought him fishing many times. But the past 84 days the old man had not caught one fish. After 40 days of not catching anything the boy left and fished on another boat. The boy still loved him and brought him food and fresh bait to fish. The old man and the boy always talked about baseball because they both enjoyed it. One day, the old man was out on the water fishing. The weather was beautiful, the currents were perfect, and he saw all birds flying over the water. He knew he had to catch a nice fish today. He saw one of his poles have a jerk so he pulled it in and it was a bonita fish, which he was goin to use for a nice piece of bait later in the day. The day progressed and he saw a real big jerk on the pole. He jumped up and held it, but the fish was not hooked yet. A couple more jerks he felt, but the fish was not taking it. Finally the fish did and he could feel that it had to be a fish of enormous size. He could not pull it up because it was so strong. He had to hold onto it until the fish was tired and decided to come up. Then when it would come up, he would take his harpoon and stab it in the heart so it would die. This fish was taking all the strength out of him and it was pulling his skiff farther and farther out. Now he wished that the boy was here with him to help him pull it up. It was 3 days later until he finally got the fish to jump out of the water. When it did he saw that it was the biggest marlin he ever saw. To regain strength and pull the fish in, he had to eat the bonita that he caught. He ate all of it and it helped his hand that was cut from the

Sense and Sensibility: A Novel of Moderation Essay -- Austen Sense Sen

  In her first published novel, Sense and Sensibility, Jane Austin brought to life the spirit of being young, in love and living in the eighteenth century. Her story revealed the heartaches and happiness shared by Elinor Dashwood, who represented sense and her sister Marianne, who stood for sensibility. Both sisters felt strongly for what they unknowingly stood for, but each needed to reach a middle ground to find true happiness. It was not until the end of the novel, through marriage, that Elinor and Marianne overcame their nature of having sense and sensibility. Although the title suggested a story of opposites, Sense and Sensibility was about moderation, and how it was applied to two individuals to create sincere joy. The Dashwood sisters were alike in many ways: they were both pretty, young and looking for a suitor. Their differences, however, far exceed their similarities. Marianne, the younger sister at seventeen, was described as "sensible and clever; but eager in every thing; her sorrows, her joys, could have no moderation. She was generous, amiable, interesting; she was everything but prudent" [sic] (p. 4). Elinor saw this with concern, for she "possessed a strength of understanding, and coolness of judgment, which qualified her, though only nineteen, to be the counsellor of her mother, and enabled her frequently to counteract, to the advantage of them all, that eagerness of mind in Mrs Dashwood which must generally have led to imprudence. She had an excellent heart; - her disposition was affectionate, and her feelings were strong; but she knew how to govern them" [sic] (p. 3). The sisters also had different ideas of what to look for in a husband. Elinor was never specific on what she looked for in a suitor; h... ...ndship, voluntarily to give her hand to another!" [sic] (p. 259). Marianne had overcome the passion she had possessed to find happiness, for she "found her own happiness . . . . [and] could never love by halves; and her whole heart became, in time, as much devoted to her husband, as it had once been to Willoughby" (p. 260). The novel Sense and Sensibility is a wonderful tale of two young sisters who were able to overcome their own personal trials to reach happiness. Elinor was able to show her passion for Edward, releasing a great burden of sadness off her shoulders, while Marianne overcame her passion of Willoughby to love another, her husband. Despite the suggestion of the title, the novel was focused on moderation, and the role it plays in creating happiness. Works Cited: Austen, Jane. Sense and Sensibility.

The duty and role of the producer

As far as the market is concerned, there is the existence of a diverse range of products that are meant for the purposes of human consumption. The duty and role of the producer is to come up with a product to be disposed through the process of marketing to the ultimate consumer. By so doing the goals as well as the objectives of the producer is the generation of profit.It therefore applies that the question of the safety as well as the health issues of the product is not the concern of the producer but a matter of personal issue of the determination of the side effect as well as the harm that may be associated with the consumption of the product.Majority of the products in the market that are meant for consumption are generally unhealthy as well as a cause of death to the human beings. In the consideration of the range of the products that poses health risk to the consumer from the range of fast foods to the tobacco products, the list can only be considered to be endless.However, all these products are usually promoted in the market through the process of advertising, highlighting the best side of the product while the knowledge about the harmful effects is in most cases concealed. However the consequent actions of the consumer are entirely blamed on the advertisement.Advertising is generally understood as the act as well as the practice of creating the awareness of the product to the consumer in view of influencing the behavior of the consumer in favor of the product. It is purely wrong to place the blame of the actions of the consumer on advertising.This kind of situation can be equated to blaming an individual who is entitled to his or her own views. The advertising agencies and the product owners should instead, take the blame. Across the majority of cultures and especially the United States the responsibility of the personal choice has been eroded and people otherwise point fingers in alternative directions (Fox 98).The concept of advertising forms a major segment in as far as the society is concerned. Through advertising, the public attention with regard to the existing products, the needs as well as the services is sensitized. There exists no boundary as to the effects aroused by the practice of advertisement with regard to the potential harm inflicted on the body of the individual.The advertising companies push the harmful products to the disposal of the user. It should however be remembered that the ultimate use reserves the final judgment with regard to the use or abstinence from the use of the product. In contrast to this fact, it has been evident that majority of the people have laid the poor choices made by the consumers on the advertising companies.The tobacco as well as the alcohol industries is among the most notable industries that have been the target in as far as the blames of this category are concerned. The concept of personal responsibilities among the majority of people have been eroded, a situation that has resulte d to the consideration of the advertising industry as a scapegoat for the poor associated with the consumers (Goodrum 145).It is an obvious fact that the majority of the individuals will be adamant in as far as the issue of admitting to the reality is concerned but all in all connecting advertisement to the wrong judgment of the consumer is not justified.This can only be taken as the absence of the potential capacity of the individual to exercise personal responsibility with regard to the choices that the individual is in a position to take as well as implement. To exonerate themselves, the poor choice of the consumer is pegged on advertising as the scapegoat.It is a common practice for people with weak willpower to blame others for the poor judgments that they make. The process of making coherent decisions is rooted in the potential capacity for the people to shoulder their personal responsibilities.The fact that an advertisement has been aired is not an implication that it should be wholly embraced but rather the individual is at liberty to enjoy or disdain the product targeted by the advertisement (Fox 158).
