Upon exploring the significance of behavioural competencies with the skill development of each employee, decision of organizational study and hr development strategy particularly with the importance of trainings as well as learning and development through an open distance learning will be tackled followed by discussing the importance and impact of employee recognition in the context of employee relation. With regards to trade union issues, the differences between multi-union, single table, single union and partnership will be discussed followed by explaining the benefits and advantages of conducting a collective consultation like redundancy, transform of under takings, health safety, pension, and work place agreement. According to Roy Ballentine of Ballentine Finn & Co.; â€Å"Getting the right people in the right jobs is important because we are running a business that depends on human capital† (Alexander, 2009). It simply means that employing a person with sufficient skills and knowledge to perform a task could enable the organization meet the business objectives. A common problem that most HR managers are experiencing today is that hiring new employees who are capable of performing the job does not literally mean that the newly employed individuals would stay with the company for a long period of time. One of the most common reasons why newly hired employees would decide to leave the company is due to the fact that they could not fit in the organizational culture or the existing team within the department. For this reason, it is a challenge for HR managers to get the right people in position. Organizational culture is a paradigm developed by individuals within the organization which over time forms a strong pattern of behaviour and belief that could significantly affect

What is steven pinker's response to media critics who are concerned Essay

What is steven pinker's response to media critics who are concerned about the harmful effects of consuming electronic media do you agree with his argument why or why not - Essay Example Currently, since many have accused new media for lowering intelligence, the level of since should then be reducing. On the contrary, the quality of science has been increasing because scientists are making use of new media. Similarly, he argues that other activities related t the human mind such as philosophy and cultural criticisms continue to flourish. Pinker further responds to the critics of new media by pointing out that experience does not necessarily shape the brain because the brain itself is not â€Å"a blob of clay.1† The brain does not necessarily copy the qualities of whatever it consumes, and therefore the effects of new media will not be as huge as implied by many. Instead of bemoaning technology, Pinker suggests that people should look for ways of exercising self control when using these new media. This will help encourage intellectual growth. Having read the article by Pinker, I agree with his arguments relating to the new media technologies. First, new media technologies have helped increase intellectual depth by allowing for multiple approaches to teaching and learning. This exposes individuals to various forms of information from a variety of sources, which makes people smart. As a student, I have benefited from these new technologies and this has greatly enhanced my knowledge in various fields. For instance, through these technologies, I am able to supplement class material with online materials obtained through search engines such as Google. As noted by Pinker, these technologies help us search and retrieve information online using tools such as social media and e-books. As knowledge continues to increase, there is the need to have tools that help in the effective retrieval, processing and storing of such information. Pinker rightfully argues that our brain power does not increase with increasing knowledge, and ther efore such tools come in handy. By sitting behind a computer for instance, one is able to obtain vast volumes of information

Timing of the Emancipation Proclamation Essay Example for Free

Timing of the Emancipation Proclamation Essay Abraham Lincoln is considered today, to be one of the best presidents of the United States. However he was despised by many at the time of his election. When he was elected a number of states in the south insisted that they would not be governed by him and wanted to secede. By the time he of his inauguration seven states had already seceded with four more following shortly after. The Confederates seceded because they feared that slavery would be ended, and they felt it was too important to their economy. Their actions are still considered to be too severe because although Lincoln was against slavery, he was not prepared to take any direct action to stop it. He believed that if he stopped to spread of slavery then it would die out in the far future. He also believed the slaves did not believe to become American citizen and should be shipped back to Africa after they gained freedom. Abraham Lincoln said he only cared about preserving the United States of America and joining the Confederacy back to the Union. Lincoln saw Fort Sumter as the perfect opportunity to bait the Confederates into war. Fort Sumter was a Union fort in South Carolina, and President Lincoln decided to send supplies there, knowing it would upset the Confederates because it shows that the union had no plans of giving it up. The Confederates respond by firing on the fort for thirty-three hours and completely destroyed it, but not killing anyone. This is considered the first battle in the Civil War and what started the fighting. The Union people thought that it would be an easy win for them but the Confederates comes strong out of the gate. The Union was struggling with finding a general that could create the winning formula. The Union lost some key battles early on; however it filled them with passion and made them hungry for victory. Eventually Ulysses S. Grant took the reins and the Union wen t on to victory. Abraham Lincoln started his presidency with no plans to directly end slavery, and the war started with the sole intention of restoring the Union. He stated â€Å"My paramount objective is to save the union†¦ and is not either to save or destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that† (Roark 369). However as the war went on it evolved and became a fight for the freedom of the slaves. Lincoln wanted to free the slaves immediately, but there were still slave states left in the Union and if he had done anything like that they might secede too, and if he lost them he knew he could lose the war. Therefore he had to wait for the right time to declare any end of slavery. On January 1st of 1863 he decided that time was right and issued The Emancipation Proclamation which gave freedom to all the slaves in the rebelling states. Also to help keep the slave states in the Union he exempted that from the proclamation. Since the Confederation did not fall under the Union, the proclamation depended on victory for the Union. The Times in London was quoted saying â€Å"Where he has no power Mr. Lincoln will set the negroes free, where retains power he will consider them as slaves† (Roark 370). While it may appear as if they are right the thought was that as they passed invaded confederate lands and captured them they slaves would gain freedom. Lincoln waited before proclaiming emancipation this because he needed to prove his worth to the Upper South. Had he passed it earlier they would have seceded and it would have been a major loss to the Union army.

Composites Used In Aircraft Structure Engineering Essay

Composites Used In Aircraft Structure Engineering Essay This report explores the uses of composites in modern aircrafts and investigates the technical effects of applying composites to aircrafts. In addition, this report also evaluates the future usage of composites in aerospace industry. Background Composites are defined as engineered materials made from two or more constituent materials with significantly different physical or chemical properties those remain separate and distinct on a macroscopic level within the finished structure. (Definition, 2010) The American Heritage Dictionary (Houghton Mifflin, Boston, 1981) comes close, with a complex material, such as wood or fiber glass, in which two or more complementary substances, especially metals, ceramics, glasses, and polymers, combine to produce some structural or functional properties not present in any individual component. The problem with even a good definition, of course, is that it is all encompassing, so that every material in the universe could in some sense be defined as a composite. (Composites Manufacturing, 2006) Composites are first introduced after crash cases of aircrafts due to metal fatigue in the 1950s. And since then the use of composites in aircrafts increases exponentially over time. Method of Investigation Information is obtained online in the form of e-books, news articles and industrial reports. Furthermore, relevant book from SP library had been used in this report. Scope of Investigation This report explores the history of composites. Besides, this report also explores the types of composites used in aircraft structure, for example carbon fiber, fiberglass and Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ aramid, as well as fabrication of the carbon fiber. Furthermore, this report discusses the technical effects and applications of composites in aircraft structure. Composites in the future such as self-repairing composites and shape memory composites are also discussed in this report. History of Composites Composites were introduced in the 1950s and 1960s, fiber-reinforced plastic, was introduced to substitute the usage of duralumin in the structure of aircrafts. Before composites were introduced, primary structure of aircrafts was made largely of aluminum alloy. Duralumin, a type of aluminum alloy, was widely used in aircrafts primary structure due to its high strength to weight ratio and good toughness. Furthermore, good corrosion resistance of duralumin makes it so suitable to be used under harsh condition. However, in 1950s, a fully loaded De Havilland Comet jet airliner crashed due to metal fatigue. This gave rise to demand of materials suitable for aircrafts primary structure with high fatigue resistance. English scientist, Norman de Bruline, was the first to propose the use of composite materials in aircrafts structures. Then, more and more composites were introduced to suit certain requirement of properties of aircrafts structure. Modern fibers, such as carbon-reinforced fibers, Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ aramid, glass-reinforced fibers and boron fibers, are the stiffest and strongest materials known. (Composites Manufacturing, 2006) Modern Composites Composites are well known for their favorable properties such as high strength to weight ratio, high stiffness, very high stress level, high fatigue resistance and good corrosion resistance. Some of the widely used composites in aircraft structures will be discussed below. In common, all composites are made of relatively weak bonding of lamination of materials. Hence, core in composite laminate is introduced to increase the laminates stiffness by effectively thickening it with a low-density core material. This can provide a dramatic increase in stiffness for very little additional weight, where lightweight implication is so crucial for aircraft structure. For example, application of honeycomb core provides stronger impact resistance to composite laminates. With its hollow cells, it provides good energy absorption and sound dampening effect to the laminates. Types There are many types of composites currently used in aircraft structure. However, in this part only carbon fiber, fiberglass and Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ aramid will be discussed. Carbon Fiber Carbon or graphite fiber is basically fiber that contains more than 90% of carbon. Carbon fibers are ideal for lightweight reinforcement, as well as high strength, high stiffness application in aircrafts structure, due to its unique combinations of properties. High-performance carbon fibers are available in a range of properties, product forms, and prices. Most of the Carbon Fibers are made from organic polymers, with chains of carbons connected to each other, such as polyacrylonitrile (PAN). (Composites Manufacturing, 2006) Fiberglass Fiberglass is a reinforcing material that is widely used in aircraft structure. More than 70% of the reinforcement of thermosetting resins is made of fiberglass. In general, the longer the fibers, the greater the strength of the fibers is. And continuous fibers are the strongest amongst all. Glass does not burn, and at high temperature glass retains its mechanical properties, up to 50 per cent of its strength at 700 °F. Furthermore, glass has excellent moisture resistance compared to metals. Thus, it is suitable for application on aircraft structures. Lime-alumina-borosilicate glass, or E glass, was the first glass developed specifically for continuous fibers production. It is designed for electrical applications, with its good adaptability and high effectiveness in processes and products, ranging from decorative to structural applications in aircrafts. (Composites Manufacturing, 2006) Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ Aramid Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ aramid, introduced commercially in the 1970s, is an aromatic long-chain polyamide polymer produced by spinning using standard textile techniques. It was introduced to replace steel in racing tires. Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ aramid is well known for its high tensile strength, low density and good impact resistance with about half the stiffness of graphite structure. These properties offer a better choice for materials used in aircraft structures. For example, Kevlarà ¢Ã¢â‚¬Å¾Ã‚ ¢ 49 aramid fiber is widely used as reinforcement for plastic composites in aerospace, marine, automotive, and other industrial applications. (Composites Manufacturing, 2006) Fabrication In general, the reinforcing and matrix materials are combined, compacted and processed to undergo a melding event. In this part, fabrication of carbon fiber will be discussed in details. Figure 1 below illustrates the brief process of fabrication of carbon fiber, from its precursor form to the fiber. Figure 1 Fabrication Of Carbon Fiber (Flow Chart, 2010) Firstly, acrylonitrile, CH2CHCN, a chemical compound derived from propylene and ammonia, is mixed with another plastic in powder form, and is then reacted with a catalyst in a solution polymerization process. In results, a polymer is formed. After that, the polymer is put under spinning process to form the internal atomic structure of the fiber. This process is done by heating up the mixture and pump through tiny jets into a chamber where the solvents evaporate. The polymer is then washed and stretched to align the molecules within the fiber. This complete process is called stretching. The final product after this process is known as precursor. Next, the fibers will undergo oxidation process. The fibers are heated in air to about 200 to 300 °C for 30 to 120 minutes, to convert the linear atomic bonding to ladder bonding. This is to prepare a more thermally stable bonding of fibers. After the fibers are stabilized, they are heated again to 1000 to 3000 °C for several minutes in a furnace. This has to be done in inert environment to prevent fibers from burning with presence of oxygen gas. As the fibers are heated, they start to lose their carbon atoms as well as non-carbon atoms while the remaining carbon atoms will form a tightly bonded carbon crystals that are aligned almost parallel to the longitudinal axis of the fibers. This process is known as carbonization. In some processes, two furnaces are operating in two different temperatures to provide a better control of heating rate. Lastly, the fibers will undergo surface treatments such as oxidation to provide better bonding properties, coating to protect fibers from external damage. (Composites Manufacturing, 2006) Technical Effects Generally, composites are superior in fatigue resistance, corrosion resistance, and high strength-to-weight ratio. These properties give composite aircrafts better fuel efficiency as well as better load capacity, as compared to the metal alloy counterparts. In addition, composites design offers lower maintenance cost compared to that of metal alloy design. Composite parts are manufactured as a whole, compared to metal parts are manufactured in the form of sheet metals and are connected by means of fasteners, the former greatly reduce maintenance cost by simplifying maintenance procedure. Figure 2 below shows the fuselage barrel section being manufactured in one piece, without the needs of fasteners. Figure 2 Boeing 787 DreamLiner Fuselage (Composites Material, 2004) However, composites are not as almighty as they have been told. For instance, most composite materials are poor in electric conductivity and such, causing them to be more susceptible to damage due to lightning strikes. Compared to metal alloy airframes, composite counterparts require extra procedure in order to take care of the electric charge from the lightning as well as static charge from friction when flying. Furthermore, unlike metals, composites break without sign or physical warning. Compared to aluminum alloy, composites do not bend when subjected to impact but break once they fail to withstand the load. Applications Composites are currently used widely in aerospace industry. Primary structures, for example fuselage, wings, ailerons, flaps, empennage, are made of composites in modern aircrafts. For example, composites contributed 50 per cent to the weight of Boeing 787 DreamLiner, whilst almost 100 per cent of the fuselage skin and wings surface are composites. Figure 3 below illustrates the usage of composites in Boeing 787 as compared to that in Boeing 777, has increased significantly. Figure 3 Goodbye Metal Planes (Goodbye Metal Plane, 2005) Secondary structures such as pressure bulkheads, floor beams, and landing gear door are also made of composites. Furthermore, composites are also used in interior. Composites In The Future Self-Repairing Composites Self-repairing composites are composites that are able to repair cracks on the aircrafts as they happen. Figure 4 below illustrates the fundamental of self-repairing composites. By designing a network of glass rods filled with resin, it is possible to stop the crack from propagating and repair the aerodynamics characteristic of the aircraft when crack happen in flight. Figure 4 Self Healing Artificial Skin (Self Repairing, 2007) However, there are limitations in self-repairing composites, for example, the supply of the resin in the network. A system with vascular network has to be developed to resupply the resin so that self-repairing composites serve their purpose from time to time. Shape Memory Composites Shape memory composites are composites that retain one or two shapes after being cold-worked. Figure 5 illustrates how shape memory composites retain shapes after being subjected to heat. Figure 5 Shape Memory (Shape Memory, 2007) This is highly useful in aircrafts design as it means the aerodynamics of the aircrafts can now be controlled according to whether maneuverability or stability is needed. Conclusion Composites are currently used as a better material used in aircraft primary structures, substituting aluminum alloy that had been used for decades. Due to composites superiority in corrosion resistance, fatigue resistance, and weight saving, it is expected that incoming models of aircrafts will use composites extensively. Application of composites in modern aircrafts once again proves that composites are more reliable than metal alloys in airworthiness. However, further development of composites should be done to overcome weaknesses found currently to further improve the safety of aircrafts.

To His Coy Mistress Essay -- essays research papers fc

Words on "To His Coy Mistress" Either you have sex with me or you die. This is a very strong statement which, when said, has to get someone's attention; and that is exactly what Andrew Marvell intends for the reader in this poem. He wants the undivided attention of this mistress so that he can scare her and rush her into making a decision the way he wants and in due time. Filled with time flavored symbolism, this carpe diem poem, "To His Coy Mistress" by Andrew Marvell, exemplifies the seize the day theme. The cyclical, life symbolizing river, the water flowing by like time, is the first place Marvell places the characters. And even though they are very far apart, time still flows by for them both. As the water flows, this concept begins to hint at the shortness of time, for them to have sex, the source of new life. He then proceeds to claim that he could love her ten years before the flood, something already ancient, and up to the end of the world, using the juxtapositioning of the two views of time enhance his argument and to convince to accept his offer by telling her of his long-term commitment for her in the short-term. This flood also symbolizes life in the fresh start of the new covenant. Because time keeps going, with or without them, they must be active participants and not just the static spectator. Otherwise, the fate Marvell relates would become their reality....

The Pitiful Campus Dining Experience Essay example -- Argumentative Pe

The Pitiful Campus Dining Experience      Ã‚  Ã‚  Ã‚  Ã‚   When I was a waiter at a local pizza parlor, the area manager would come in once every two weeks and give the restaurant an inspection. He would watch us through the course of an evening, and when the crowds subsided, he would gather us all around and give us our review. At the onset of every debriefing, as they were called among the crew, the first words from his mouth would always be, "From the moment the customer enters those doors, his dining experience begins. He will form an opinion in his mind about us, and it is your job to make sure that opinion is good! If it isn't, I'll know about it, and then so will you." Even though my experiences at that restaurant are a year behind me, whenever I eat out I always keep in mind the customer's opinion -- especially when I am the customer. When  Ã‚   State students eat at the campus facilities, they form opinions about their dining experience just as any customer would, and whether that opinion is good or bad is the responsibility of the food service. Recently I conducted a survey to determine the student opinion of the food service at  Ã‚   State. My purpose was simply to see if the students were satisfied with the overall performance of Service America, the catering company that handles all of the campus dining facilities. I surveyed fifty students over a period of two days at different times and locations. All of those I surveyed ate at least occasionally at one of the dining facilities. The survey rated such aspects as variety, quality, and taste of the food offered as well as the student's opinion of the prices they paid and overall service they received. The ratings given were initially somewhat mediocre. ... ...ts known will have them resolved in one manner or another, and by solving the students' problems as best they are able, Service America will ensure good public opinion and keep its contract. This arrangement is beneficial for both parties involved, and since my results concluded that there is no widespread discontent with the food service, there is no real justification for procedures any more radical than those I have suggested. Perhaps a monopoly does exist at  Ã‚   State in the form of Service America, but it is a monopoly that is ultimately controlled by its patrons, who have the freedom and the power to act on their opinions. The choice for action lies in their hands.      Sources Cited Goodman, Stephanie. "Dinner Is Served--At the Mall." Adweek's Marketing Week 24 Ju1y 2013:30-34. Loprete, Michael.

The Secret Lives of Bees

The Missing Piece of the Puzzle Delis Lilies Kettering College Medical School of Arts The most obvious symbol of the Black Madonna in the writings of Sue Monk Kid represented a character of strength, endurance, stability, and a loving Mother. Many people ask themselves this question, â€Å"What is my true purpose in life? † Or â€Å"Who am I meant to be? † Most of the time they get an answer based on a religion, inspirational readings or thought. The Virgin Mary, the Black Madonna, is history's example of a mother.She is sensitive and firm, relatable and divine. The Black Madonna teaches Lily that she has mothers all around her, Rationale's protection, Mayo's caring, and Augustus love, Lily finds a mother in everyone around her, including herself. Sue Monk Kid begins her story with a character by the name of Lilly Ray, a fourteen old girl who lives with her abusive father, T-Ray Brown. Lily had the tragic experience of losing her mother at a young age. She never had the intimate relationship that comes with having a mother in your life.She never experienced the soft voice or embrace of a mothers loving arms, something she longed for all her life. Life has a funny way of eating us down the path we are destine to take, but at the same time, comforting us with situations that are unpleasant. The people that we meet on our Journey are people we are destined to meet. Rosalie, a black house keeper who lived in the south and worked for T-Ray, was one of the closes things Lily could call a mother figure in her life. Lily and Rosalie shared a common ground.The two loved each other and at the same time, longed for something deeper in their lives. Sue Monk Kid teaches us the importance of relationship and the power of female community. Lily longs for her mother and cherishes the few possession of her mother. She keeps a box of her mother's memories buried in the orchard. In the box, there are photos, a pair of white gloves, and a wooden picture of a black Ma ry with the words â€Å"Tiburon S. C. † on the back. Every time Lily feels alone or unhappy, she digs the box up. Sue Monk Kid demonstrates the significance of mothers to adequate human development.Everyone, regardless of circumstance or color, needs a mother. Lily's journey brings her to a place where transition and fate kisses face to face. Unfortunately, it also ends a relationship with her father whom she loved but didn't understand. The Black Madonna serves several functions in Sue Monk Kid writing. It symbolizes as a surrogate mother to Lily seeing this was the only image she could relate back to her mother. However, the real meaning and symbolization comes from Catholic Catechism. Catholics place high emphasis on Marry roles as the protector and intercessor.The Church holds the Blessed Virgins Mary, mother of Jesus Christ, in special regard. They feel a strong personal relationship to Mary as Lily did to Rosalie and the Bodyweight home. She is in a sense, mother to all . Just as Lilly turned to August for love and support, the Catholics turn to Marry Madonna for the name type of affection. The Black Madonna, through the teaching of August, gives Lily the strength and confidence to begin to change the way she thinks about her father's behavior. Sue Monk Kid captures the bravery of Lily's actions.In a time when slavery was still present and in its strongest form, Lily was able to gather strength from the Madonna and her circle of friends to make her passage way to wholeness and a new beginning. Many different faiths and religions view the icon ‘Mary Madonna' in different ways, but for Lily's life, it would be the life changing motivating factor to start her on a new road of healing and freedom. Lilly sees honey for sale with the same picture of a black Mary that her Mother had. She discovers that a women name August Bodyweight sells the honey and Lily travels with her friend Rosalie to the Bodyweight home.Lily meets the sisters, August, June, and May, who lives in this bright pink house. She was so nervous of the unknown; she began to lie to them about her past. It is human nature to hold onto to something from our past that brings us shame. We cling to the memories of the past; for it is there we can find peace and comfort. August is a black single woman who lives with her sisters and helps run her family business. She invites Lily and Rosalie to stay in the honey house. As time moves on, August develops a special bond with Lily becoming a surrogate mother to her.In each person's life, much of the Joy and sorrow revolves around attachments or affectionate relationships making them, breaking them, preparing for them, and adjusting to their loss by death. Among all of these bonds, are the special bonds – of a mother or father we cherish the most. Bonding does not refer to mutual affection between a baby and an adult, but to the phenomenon whereby adults become â€Å"Committed by a one-way flow of concern and affec tion to hillier for whom they have cared during the first months and years of life,† (hacker 20011). According to J.Robertson in his book, ‘A Baby in the Family Loving and being Loved,' individuals may have from three hundred to four hundred acquaintances in their lifetimes, but at any one time there are only a small number of persons to whom they are closely attached (Robertson, 1982, p. 53-54). He explains that much of the richness and beauty of life is derived from these close relationships which each person has with a small number of individuals such as, mother, father, brother, ester, husband, wife, son, daughter, and a small cadre of close friends (Robertson, 1982, p. 3-54). Attachment is crucial to the survival and development of human kind. August makes the most important statement Lily would ever receive about the black Mary and who she is; â€Å"Our Lady is not some magical being out there somewhere, like a fairy godmother. She's not in the statue in the parlo r. She's something inside you† (Kid, 288). It is at this point Lily discovers where her true strength comes from. She sees it inside of her. As this story unfolds, Lily is now able to make peace with the past and with her father.She understands the hurt she was feeling but never took the time to see that T-Ray was also dealing with his own daemons and hurt. It was the hate and bitter heart oft-Ray that drove Lily on her journey, but it's her destiny that leads her to a new hive of mothers, and falls in love with who she is inside.
