A Life Lesson from My Grandma Essay
The tears rolled down profusely as I held the telephone receiver in my hand. My aunt was still on the other end, demanding that I immediately rush over to Grandma Maryââ¬â¢s house. At this instant, my gut instinct responded by tightening up indicating that something was definitely wrong. And it was only then; memories of her youthful days flashed across my mind, reminding me of her mantra, ââ¬Å"You must never allow anyone to steal your joyâ⬠. And it appeared as if she was standing right beside me, but I knew it was just a fragment of my imagination. I confirmed there and then to myself, I recognized now that I had lost someone, but I would have something with me for life, the value of unconditional love my grandma often displayed amongst her family and her neighbors by extension, and she would always reiterate how much she wanted it to live on. Granny Mary was like a female Goliath. Blessed with a dark chocolate skin tone, moles and wrinkles canvassed her face which we often referred to as the storylines of her life. But the positivity she gave off could connect a grounded wire on a cold winter night. How she did it, she alone knew. I remember her making ends meet, and providing food for her family after two failed marriages. As the other half of her twin, Uncle John would pay his sister to do his laundry, cook his food and maintain the downstairs of the home which he occupied. And yes, pretty amazing how this money brought up six kids and assisted my sister and I as the two first grandchildren in the family. Not only did she raise her grand kids, but the entire neighborhoodââ¬â¢s children were taken care of by ââ¬Å"Aunty Maryâ⬠also, a name she would always be remembered by. I can still recall how many days the neighborââ¬â¢s kids will come without food or clothes, but when they left, their tummies were filled, and late evening shower already taken. We would all surround granny as she read a bible story and explained the role of each person mentioned in theà bible. It was as if her joy was ensuring that all children were always happy and knew the value of love. And yes, this stood out most, because to this day, I share the same sentiments when dealing with my daughter and my niece, or all children I interact with on a daily basis. To this day, I could count the number of times I saw a toothy smile on her almost daunting face, after that late December afternoon when the hospital called to say my Uncle Brian passed away after being involved in a motor vehicular accident on the Solomon Hochoy Highway. She continued to emphasize that we were totally in control of our own happiness, and we should live life to the fullest always displaying love and making sure all is well with our soul as we never know when the good Lord will call us home. I remembered her kneeling to pray with her every night before we go to bed. She embedded that prayer was the answer to every problem you can ever encounter in this life and happiness is within oneââ¬â¢s self. Grandma Mary would often have us assist her when she picked peas or fed the chickens in the backyard. We watched the chickens developed from baby chicks to mealtime. And yes, weââ¬â¢d joke about it when it was time to catch them to have grandma prepare some great soul f ood for us. In April 2012, I was able to display the said qualities Grandma Mary embedded in us. I gave birth to a still born baby boy, and all I saw after giving birth, was my grand-motherââ¬â¢s face. How sheââ¬â¢d often say God is ever to wise to make a mistake, and God sees what we donââ¬â¢t. Although I didnââ¬â¢t want to hear that at that time of grief, I clearly remembered dreaming her one night, giving me confirmation that all would be well, and continue to love and have faith in God. And as I thought about her the morning after I was discharged from the hospital, I made hot cocoa, and the aroma took me back to twenty years ago when my grandmother was alive. Weââ¬â¢d wake up to the aroma of hot cocoa and her favorite Jim Reeve would be blasting through the house, ââ¬Å"If heavenââ¬â¢s not my home, then Lord what will I do?â⬠And it was as if she strengthened me to look forward and not regret. I remembered her mantra, and I did not allow the death of my son to steal my joy. I still had my daughter to brighten up my days, and prayers assisted me in trusting and believing that God had better plans for me. As an individual, I can associate part of my grandmotherââ¬â¢s journey to that of mine. No mother comes on this earth with the intentions of having to bury their own child, but all in all, life has to go on. And not just go on, but I am in control of my own joy. The qualities she left us with have continued to reign throughout my family, and every time I sit to tell a story about Grandma Mary, I can safely associate her with love, faith and God. The aroma of hot cocoa today brings a smile on my face, and each time I hear a Jim Reeve play, Iââ¬â¢ll see her wrinkled face. There is no greater joy in having a loved one live on although they are no longer with us in body. I am one hundred percent guaranteed she is indeed happy with the positive value we continue to display. And the deep voice ringing through my head, ââ¬Å"You must never allow anyone to steal your joyâ⬠.

Lord of the Flies – Piggy
The conch, glasses, and brains are all symbols in Lord of the Flies by William Golding. In this novel, a group of school kids crash into a deserted island and fight wilderness, fear, and themselves to survive. Piggy, being one of the most vital characters in their survival, is often disrespected and overlooked. This is persistent throughout the novel, and can be attributed to his weight and nerdy appearance. Generally, Piggy means well, and tries to help the boyââ¬â¢s survival on the island. Piggy, an extremely complex and intelligent character, contributes to the boyââ¬â¢s survival by using logic and brains. Piggy, along with being the brains of the island, is also a very complex and misunderstood boy. ââ¬Å"Piggy is a much more complex character, than the simplistic interpretations so regularly adduced will allowâ⬠. (Reilly. online). This states that Piggy was an extremely complicated character, and is often overlooked by not only characters in the book, such as Jack and Ralph, but also by readers. He is also described as a brainiac by Golding himself, ââ¬Å"Piggy, for all his ludicrous body, had brainsâ⬠. (Golding 71). This emphasizes to the reader that Piggyââ¬â¢s brain is being discounted due to his stature, and this causes readers to discount his intelligence, however, it brings the readerââ¬â¢s attention to them being naive. This last quote also reinforces the concept that his body is causing his smarts to be overlooked ââ¬Å"Piggy lacks the looks but has the know-how. The trouble is that he knows but cannot do and is relegatedâ⬠. (Reilly. Online). Lorenz 2 Broken down, this shows that Piggy is a resource that the boys need to utilize, but fail to, and instead they treat him like a set-back, only because he is weak. He has a lot more to offer than just physical labor, and should be honed for using his brain to problem solve, or be inventive. It is quite obvious he was often bullied for his weight at school, due to the fact that kids called him Piggy there too. Piggy also has strong feelings for is Aunt, and often uses her advice to his advantage when speaking to Ralph about a variety of issues. This is shown many times throughout Goldingââ¬â¢s writing, and brings the voice of an adult onto the island. Piggy contributes to the group on various occasions. The first is when he discovers the shell. It is Piggy who is first excited by the shell, but only as a curioâ⬠. (Kinead-Weekes, Mark. Gregor, Ian. 39). Piggy is the first to find the shell, and even states that it would be a great idea to use as a way of allowing everyone in the groups voice to be heard. This method with the shell is used throughout the entire novel, up until the falling action. Piggy is also the voice of reason during th e debate about the beast. He argues on the side of logic, and is not swayed by the littlunââ¬â¢s opinions. ââ¬Å"So letââ¬â¢s hear from that littlun who talked about a beast and perhaps we can show him how silly he isâ⬠(Golding 78). This is the best example Golding gives of Piggyââ¬â¢s logic throughout the novel. Amongst the mass panic that is brewing on the island, Piggy still has a clear mind and will not believe in simple hear-say, or rumor, he believes in fact, and until he sees that beast, it will not exist to him. He also seems a little cold, being the smallest bit rude to the littlun who is afraid. Piggy tries to take lead numerous times, and is not taken seriously. However, when Piggy helps out Ralph, and doesnââ¬â¢t take the lead in speaking or assigning jobs to other survivors, he is taken seriously, and does a great job at what he is doing to help out. Lorenz 3 ââ¬Å"[Piggyââ¬â¢s] common sense is evident from the start as when he organizes the meeting and tries to make a list of everyone presentâ⬠. (Reilly. Online). Patrick Reillyââ¬â¢s view on Piggy is spot on. His common sense is immediately shown during the scene of the first meeting, and makes the reader think he would be critical to the survival and rescue of the group. In addition to Piggyââ¬â¢s brain helping the boys survive, other aspects of Piggy were used, such as his glasses. Without Piggyââ¬â¢s horrible eye sight, and him needing to wear glasses, the boys would never have been able to start a fire, a fire that ultimately led to their rescue. This is very ironic considering Piggy was killed before he would ever see rescueâ⬠¦ a rescue that without him would never have happened. Golding did this to reinforce the importance of Piggy in the novel. It showed that no matter how useless he may have seemed, he still was the one that helped the most, in the long run. He was the most important boy to be on that island. He, in reality, saved Jack, an abusive boy who harassed him ever since they crashed, and Roger, the boy who threw stones, and the boy who murdered the innocent Piggy. Though Piggy reaches his greatest stature at the moment of his death, it is also the moment of his greatest blindness, rendered for us at a level far deeper than his lost spectaclesâ⬠. (Kinead-Weekes. Mark. 43). Piggy was completely blindsided from Rogersââ¬â¢s boulder. This moment in the novel makes readers realize the tragedy of Piggyââ¬â¢s death. The shattering of the glasses represents his knowledge and insight turning to dust, all in front of the very people he saves, from the cage that is the island. The conch was also with him at the moment of his death. This is significant because it symbolizes the shattering of all that Piggy believed in. He truly believed the conch would save him from anything on the island, and in the end it simply did not work. Lorenz 4 Perhaps Piggyââ¬â¢s greatest example of insight, however, was his speech on the monsters that Jack and Roger have become. ââ¬Ëââ¬Å"What are we? Humans? Or animals? Or savages? ââ¬â¢Piggy rages as the assembly lurches toward darkness, and his questions are not restricted to the wicked Childs-play of beastly boys on a tropic islandâ⬠. (Reilly 7). Piggy shows that he realizes what is happening to the island, and that he sees the conflicts that are occurring between Jack, Roger, and Ralph. Piggy almost predicts that the savagery will get worse. This is a very good example of Goldingââ¬â¢s foreshadowing throughout the novel. This character was, for me, the best part of the entire literary work of The Lord of the Flies. Piggy was an extremely complex and intelligent character, he contributed to the boys survival on many accounts, and was the adult that all of the boys wished they had in the end. Piggy was complex in his mind, and his actions, as well as intelligent when it came to problem solving, and advising Ralph.
Growth Strategy Analysis Of Samsung Essay
INTRODUCTION The Samsung Group is a multinational conglomerate corporation headquartered in Samsung Town, Seoul, South Korea. It is the worldââ¬â¢s largest conglomerate by revenue with annual revenue of US$173.4 billion in 2008 and is South Koreaââ¬â¢s largest chaebol. The meaning of the Korean word Samsung is ââ¬Å"TriStarâ⬠or ââ¬Å"three starsâ⬠. As stated in its new motto, Samsung Electronicsââ¬â¢ vision for the new decade is, ââ¬Å"Inspire the World, Create the Future.â⬠This new vision reflects Samsung Electronicsââ¬â¢ commitment to inspiring its communities by leveraging Samsungââ¬â¢s three key strengths: ââ¬Å"New Technology,â⬠ââ¬Å"Innovative Products,â⬠and ââ¬Å"Creative Solutions.â⬠ââ¬â and to promoting new value for Samsungââ¬â¢s core networks ââ¬â Industry, Partners, and Employees. Through these efforts, Samsung hopes to contribute to a better world and a richer experience for all. Samsung Group formed several electronics-related divisions, such as Samsung Electronics Devices Co., Samsung Electro-Mechanics Co., Samsung Corning Co., and Samsung Semiconductor & Telecommunications Co., and grouped them together under Samsung Electronics Co., Ltd. in 1980s. SAMSUNGââ¬â¢s aim is to develop innovative technologies and efficient processes that create new markets, enrich peopleââ¬â¢s lives and continue to make Samsung a trusted market leader. Today, Samsung Electronics global presence includes a total of 111 subsidiaries in the form of production subsidiaries, sales subsidiaries, distribution subsidiaries, research laboratories and eight overseas business divisions representing North America, Europe, China, Southeast Asia, Southwest Asia, Central and South America, CIS, the Middle East and Africa. Porterââ¬â¢s Diamond Analysis for Korea/Samsung Product Dimension To build a unique competitive advantage, Samsung followed a well laid out product growth strategy. These strategies can be examined under (a) product life cycle (b) product price level and (c) product diversification. Samsung followed a reverse order if we look from the product life cycle perspective. It started its operation in 1971 with manufacturing monochrome televisions which were in the declining stage inà the advanced market. It then went on to manufacture colored televisions in 1977 which had already reached the mature stage in the PLC in other markets. It tapped the videocassette recorder (VCR) and microwave ovens (MWO) in its growth stage in the market by bridging the technology gap and reaped revenues. In early 1990ââ¬â¢s SEC manufactured niche products such as DRAMs and digital videodisk (DVD) and entered this market in its introductory stage through agility, innovativeness and creativity. In 1992, Samsung became the market firm to many companies by being the largest producer of memory chips and second largest chip maker in the world only after Intel. Through innovation Samsung manufactured its first liquid screen display in 1995 and within ten years became the worldââ¬â¢s largest liquid-crystal display panel. Tapping the smart phone market in the growth stage, Samsung became the worldââ¬â¢s largest phone maker by unit sales in the 2012. From the price perspective Samsung started manufacturing products that were low end of the price range and then gradually moved up to the niche end products using innovation and high end technology. Starting from low end products was a strategic choice as there was low national income and the market had limited purchasing power, the JV partners were unwilling to share their technology and the availability of a niche market in US for the low end models. Samsung product path choice has moved from commodity product to high end niche product market as it now captures the global market. Samsung has strategically limited its diversification in the electronics-related area only. It follows a related product diversification strategy. It started with consumer electronics and home appliances, and then moved to personal computers and peripherals, communication equipment, semi-conductor and then mobiles. With the aim of capturing the strategic fit by sharing technology and management, in 1998, SEC merged with Samsung Semiconductor & Communications. In 2006, Sony & Samsung formed a JV S-LCD Corporation to co-operate and provide a stable LCD supply to both the manufacturers. These diversifications have helped Samsung get a balanced revenue structure from its products. Phase 5: Attaining technological competence whereby product and process innovation start to appear throughout the company. During this process Samsung made serious efforts to develop its own product design competence. It started to increase in-house R&D budgets and stepped up its efforts to assimilate advanced foreign technologies and to develop new product. Having successfully caught up with foreign technologies for most conventional consumer-electronics products, SECââ¬â¢s management accelerated its technological capability from reverse engineering to innovations in advanced consumer electronics, PCs and peripherals, semiconductors and communications equipment. To support this strategy, Samsung increased its R&D budgets. There was an accelerated gap reduction from the other major competitors of the world. The accelerated gap reduction may be attributed to the synergy effect of three factors: In-house R&D capability with a critical mass of more than 7,300 researchers. Availability of multiple technology sources, such as licensing. Technology alliances with advanced companies, overseas research centers in advanced countries, and foreign high-tech companies owned by Samsung. Intensity of effort by management and personnel in research and product development. Samsung is one of the leaders in OLED display research and the clear leader in AMOLED production. OLED Displays are thinner, more efficient and offer better picture quality than LCD or Plasma displays. A lot of research is being done on Innovative WLAN technology from Samsung Electronics for the wireless business environment to remove the issues with have with the existing WLAN. Manufacturing Dimension Manufacturing system was the third dimension that the Samsung controlled. Samsung always wanted to benefit from the economies ofà scale and scope. They had two strategies that is to either get vertically integrated to support the mass production of television or alternatively, depend on CKDââ¬â¢s from joint partnership and other suppliers from Japan. The main reason for this strategy was because of the lack of capability to produce the parts locally. However, Samsung soon realized that the foreign tie ups involved huge risk and transaction costs and hence decided to go with the minimally integrated manufacturing system locally. Hence Samsung built a cathode ray plant, a parts and components plant and CRT glass plant. In 1980ââ¬â¢s, a large number of independent small and medium sizes businesses mushroomed due to technology assimilation in Korea. Now, Samsung was so good in technology and quality that they could start outsourcing anywhere and anytime. The Samsung started its overseas production base. The firstà location was the Portugal and by 1995 they had twenty bases globally which accounted to a huge economies of scale and scope. The Samsung was sensitive to the changing needs of customers and hence moved from mass production to flexible manufacturing system to accommodate a new product strategy by late 1980ââ¬â¢s. Samsung introduced in multiple product models to meet the fast changing demand of the people thereby man aging shorter product life cycles and competition. In early 1990th Samsung was still perceived as a conservative manufacturer and always associated with bargains. Samsung realized that with its lowà pricing strategy it can only compete in the lower market segment whereas in upscale market technology and brand are competitive means. Samsung then onwards decided to penetrate the upscale market and gave up lower-market in order to exalt its brand image. It repositioned all series of its products such as mobile phone, consumer electronics and memory flash to upscale market. Corresponding to Samsungââ¬â¢s new position in the market it has relatively higher price in its category. Higher pricing would bring more profit and at the same time improves the brand image. Samsung is now developing products for the Indian market and tailored to their needs. Samsung has clung to its premium positioning, with products that emphasized design, aesthetics and cutting-edge technology and prices that were commensurately higher. In 2005, Samsung introduced over 100 new products such as flat panel, LCD and plasma TVs, top-end refrigerators, home theatre systems, digital cameras and camcorders, MP3 players, notebook computers and mobile phones which were sold in lifestyle category. It is the market leader in LCD televisions and super-premium, side-by-side refrigerators and claims respectable market share figures in other product categories as well. Theà most important strategy for competitive advantage has been the principle of survival inequality, which states that cost should always be lower than price, and price should always be smaller than product value. Apart from price, another important factor which was strategically exploited by SEC was the concept of speed management by emphasizing on good decisions and fast implementation. The company exploited the opportunities arising in the world market by making timely decisions on product development and technology acquisition ahead of its competitors, as well as shortening the time to implement for example: : VCRs, MWOs, and memory chips In 1970s, the most important factor for Samsungââ¬â¢s strategy design was to create a relevant product choice. This decision was important as it would have affected 1. Technology acquisition 2. Marketability 3. Cost competitiveness To reduce its threatening profile to the technology supplier, SEC took products in the declining stage of the product life cycle. Further, to give an incentive to the technology supplier, the Joint venture form was used, whereby parts and components would be imported in the form of CKDs from the joint venture partner. To gain market experience and overseas sales network, OEM was used. To build up its brand image, SEC chose commodity type products in the low-end price range. SEC chose massà production as its strategy to exploit low-end commodity products in declining stage and Koreaââ¬â¢s high quality and low wage labor. This lead to a higher learning rate and steeper decrease in costs which helped reduce the prices further.

YUManagers today must be able to manage change so that an organisation Essay
YUManagers today must be able to manage change so that an organisation can respond to the influences from external environments. Critically analyse this - Essay Example In this paper, reasons and factors associated with organizational change will be discussed in order to evaluate the managerââ¬â¢s role in administrating and implementing such organizational changes. As the society continues to change and evolve their demand, there is always need for variety of products and services, organization should be flexible enough, as they have to stay competitive. The businesses which survive for a long time and earn profits are the ones who accept the changes as they exist. There are two types of changes that occur in an organization that is planned and unplanned. Planned changes mean that an organization is bringing change deliberately by taking decisions, while, unplanned change is due to some unforeseen factors which can take place any time without informing. There are two factors which force organization to revaluate their operations, they are internal and external. Internal and external factors both can cause these changes (Oreg, Michel, and By, 2013). According to Smith (2013), Globalization affects organization as there are companies which operate in different country and each organization has their own culture which is because an organization cannot make a standard rules for every branch. Managers have to adapt a different culture when they are transferred to other branch and they should be flexible enough to do it. Entrance of a new competitor in the market brings lot of change as now organization becomes more serious about their product sales because they are in constant fear that their market will finish if competitor gets the market demand. So, the existing company try to change their work culture to stay dynamic (Cummings and Worley, 2014). A change in workforce diversity also brings change to a company. Previously, only men use to work in some company but now, women also work which changes the environment as the culture becomes more ethical and decent. Now a

INDIGENOUS CULTURE IN THE RAINFOREST BIODIVERSITY Essay
INDIGENOUS CULTURE IN THE RAINFOREST BIODIVERSITY - Essay Example These beliefs combined to create a complex system of farming and recycling of the rainforest's products they used in their daily life. This sustainable agriculture has been in use for several thousand years (Hartmann 2005). It is believed that the Kayapo are an ecologically evolved population and are an example of living in balance with the ecosystem. They are generally non-aggressive and have a rich tradition of rituals. They are an ancient culture that has its foundations in seasonal farming and gathering. Beliefs and ideals surrounding the issue of using the rainforest, and the purpose of the rainforest, are passed from generation to generation through socialization. Socialization is the process where people learn the customs and acceptable behaviors of the community in which they live. Customs are the traditionally accepted norms, standards, and ways of doing things. Often these customs are passed through rituals, a formal ceremony that is usually symbolic. The symbolism represents a belief and this is shared by a group such as a family or community. By socialization, a culture passes its customs and norms to the next generation and they develop a set of values based on these beliefs, customs, and norms. Values are the abstract belief in a system of right, wrong, fair, and decent.

Social Issue Essay Example | Topics and Well Written Essays - 1750 words
Social Issue - Essay Example I. Thank You for Smoking At times, the feelings that sound produces is so compelling that albeit it contradicts we understand to be scientifically true, we hold to it anyhow. Although we understand, for instance, that since space is a vacuum sound cannot be transmitted in it, we are entirely obliged by the sounds of intergalactic battle or only spaceships travelling at perverting speed in almost every space. Conversely the explosion of a gunshot never sound as enjoyably long or loud in actual life as they do in Thank for Smoking Again with the bass cranked way up. Ultimately, in many of those great Hollywood musicals, the greatest songs are not really performed by Audrey Hepburn, but by little known singers like Marnie Nixon, whose faces and statures donââ¬â¢t seem as attractive on-screen a those of the key stars. The director of Thank you for Smoking was keen on resounding applause for Nick Naylor huge sum than the real viewers of extras is able to offer. Thank you for Smoking ha s sound tracks that augment sounds that are not effortlessly available as ambient noise. At times, sounds can be amplified to a film from the annals of sound effects. There is also sound prop, including the floor, which has offered different forms of footfalls. Thank you for Smoking rolls on the screen, and the sound artist has matched the type of sound the filmmaker wanted to the images projected (Leo 1). In some scenes the images changes from solid, sprightly colors that bounce off the screen to a darker, grainer, more dark and dowdy, less colorful appearance when the lead character is away from Loringââ¬â¢s. In general, the contrast works perfectly well, and the image actually appears its best whereas the setting is at the Loring household. The episodes, such like as standard shot of Juno after the start of the movie, appears exceptionally soft. A Reddish tint appears to find its way in at times, noticed frequently in skin tones. All the colors are a bit dreary, certainly on t he end of the spectrum and entirely opposite of Thank You For Smoking. Better yet, it is effectual and establishes the mood of the movie. The lighting Juno however will quite never be reference grade material on Blue ray, the lighting is definitely a plus, and recreates the mood of the movie with a laidback authority (Leo 1). The editing of the film Thank for Smoking has both its strong and weak points. But the continuity editing errors seem to surpass the editing strong points. For instance, in the last dinner meeting of the Merchants of Death, the gun lobbyist gets a share of pie with cheese on it. He takes a small bite; consequently the alcohol lobbyist assaults it with her fork for a bite, hauling all the cheese off and tumbling the little American flag in it. The next continuity mistake is shown in the subsequent shot; a lock up of the dessert, all the cheese is back on it and the flag is vertical again. Finally when they are editing their last dinner, the cheese atop the apple pie becomes unmelted and then melted continuously between shots. The other editing error that is seen in the movie is during the Subcommittee Hearing episode. The person slumped on the seat comfortably behind Nick Naylor, on the left, transforms repeatedly between scenes. Right before he is requested to come forward, the seat is taken by a certain lady

Human Sexuality Essay Example | Topics and Well Written Essays - 750 words
Human Sexuality - Essay Example Whether it would be positive or negative, the power of research and its importance, are undeniable and relevant. For any researcher(s), it becomes the question first and foremost, as to what any long term impact the individual(s) work, would have had on the ability for greater understanding. Articles and research papers are often times written by those who seek to research issues and then wish to deliver what they find to the rest of the world. Others may also wish to produce articles themselves, only this time, on assessing the impact of the work of others, such as the case would be with John Bancroft. In his work 'Alfred C. Kinsey and the Politics of Sex Research', Bancroft looks to the work done by Kinsey and the response of others to the research itself. With that being said, in regards to Kinsey, "It was evident from his own research, and has been confirmed in various ways since, that major changes in sexual behavior had been underway through much of the first half of the 20th century," (Bancroft, p.2). This statement in itself, would give credence to the validity of Kinsey's work and show the need for greater study and debate. The article discusses the attention paid towards contraception and how the debate would consider, for instance, the use of contraception and its ability to control the size of average families. From a social standpoint, there would be those that felt it was important to have the opportunity to be aware of such issues and others would think that an issue like sexuality, should be kept in the confides of the home and in the bedroom between a man and woman. While it would have been easy to single out Kinsey for his research, it is important to note that, "He was not the first to report results of sex surveys in the US," (Bancroft, p.3). With that in mind, it would be fair to classify Kinsey as one of many, who would have put together studies on the matter at hand. Author Bancroft asserts, regards to assessing Kinsey's impact, "But one clear part of Kinsey's legacy is that sex became less mysterious," (Bancroft, p.4). When certain things have not been discussed in any great detail before, they can often times seem to some, as being unknown and dangerous even. Kinsey's work would take away the disguise and uncertainty about regular human sexual activity and reveal it to be nothing more, than typical behavior that would occur among healthy human beings. His greatest desire would be to reveal the distinct natures of male and female human beings and how each one would approach sexual intercourse. Sometimes, after research has been performed, the results lead to the production of revised guidelines. This would be true as a result of Kinsey's work. Based on his findings, "The American Law Institute, after much debate, published its revised Model Penal Code in 1995. This was clearly influenced by Kinsey's findings," (Bancroft, p.4). The author further goes on to detail that, as a result of Kinsey's work, the revised Model Penal Code would make it so that such things as being a homosexual, living together when you were not married, as well as the sexual activity of two people who were willing participants, were no longer seen as crimes. With such a revision taking place, it would lead many to consider the influence of Kinsey in the area of sexual activity, to be considerable and not to be

Organisational behaviour - Essay Example This department would require less personal factors, such as meeting vendors face-to-face at the social level, which would appeal to the authoritarian personality. Intuitive-thinkers would likely perform well at a company such as Google which uses a more idealistic type of organisational structure which encourages ongoing feedback. Workers at this organisation are encouraged to build relationships with colleagues and managers and to give their unique innovations about how to change process or improve business services. This company seems to have the controls and divisions of labour necessary to make the business function, but is idealistic in terms of long-term strategy and scope. The IT would perform best in the customer care division, solving abstract problems of consumers related to their computer systems or business software. The intuitive-feeler would enjoy working with an organisation like Save the Whales, where management would be very broadly defined and it would be a more self-managed environment.

Oppositional Defiant Disorder Term Paper Example | Topics and Well Written Essays - 4250 words
Oppositional Defiant Disorder - Term Paper Example The condition commonly affects individuals during childhood. The concern of the medical authorities regarding ODD can be attributed the high percentage of children diagnosed with the condition. In fact, it is considered as the most commonly diagnosed mental health condition in children (Hamilton and Armando, 2008, p.861). Based on the studies conducted in the community level approximately 3 percent of children have ODD with the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) description as the sole basis. When other parameters and criteria were considered the prevalence ranges from 1 to 16 percent (Hamilton and Armando, 2008, p.861). The paper is aimed to define and to discuss ODD and the different pertinent concepts related to the condition such as the symptoms, risks, management methods, treatments, and related researches and studies. The said objective of the paper can be achieved through the data gathering from significant academic and medical references, e.g. journals. In addition, the main focus of the process is the educational perspective which is either to educate the public or to present the methods of educating the individuals with ODD. Definition of ODD Oppositional defiant disorder, ODD, is officially defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. ... chool years but due to other developmentally troublesome behavior that can also be observed, the method of diagnosis is based on more than one symptom or criterion (Hamilton and Armando, 2008, p.861). Upon the determination of the meaning of ODD, the methods of diagnosis and the symptoms are needed to be given attention to achieve better understanding of the disorder. It is also important to focus on the methods of treatments and management of ODD since it is known as a subset and a precursor to a more serious condition referred to as conduct disorder (Chakraburtty, 2009). Recorded data show that one third of the children diagnosed with ODD will develop into conduct disorder while 40 percent will lead to antisocial personality disorder during adult years (Hamilton and Armando, 2008, p.863). The oppositional behavior of the children of the children ranges from passive to active forms of non-compliance. Ignoring the direction given by adults such as parents and teachers is an example o f passive ODD. Active non-compliant behavior ranges from mild refusal to angry rejection of parents or elders commands and guidance (Matthys and Lochman, 2010, p.1). There are levels of opposition from children and adolescents which can be considered normal for their age. Thus, the determination of the levels of oppositional behavior considered abnormal is needed to be given attention for the early diagnosis and treatment of the problematic child. Methods of Diagnosis of ODD There are eight standard symptoms included in the description of ODD as the bases for diagnosis. Four of the eight symptoms of the condition should be present for an individual to be considered to possess ODD. The standard symptoms include: ââ¬Å"lost of temper; argument with adults; defying adultsââ¬â¢ requests and/or rules
Analysis of General Environment Essay Example for Free
Analysis of General Environment Essay HSBC Bank (China) is one of the first foreign banks to incorporate locally in mainland. As a foreign-owned bank, HSBC has the largest services network among foreign banks, targeting the middle-class individuals and business-oriented individuals in China. With the globalization, China is seen as the biggest market in the world. The general environment will bring great effect to the future development of the HSBC (China). The specific analysis is as follow. 1. Demographic Environment China has the largest population in the globe that the number has already reached 1. 4 billion. Most of the people are living in the east and middle areas. In other words, the middle and above-middle-class people assemble in these two areas with the demand of bank service. (National Bureau of Statistic of China, 2011) As the societal pressure growing heavier, less people are willing to give birth to baby so that the problem of population aging arises. According to the reform and opening policies, the east and south areas are better developed than the central and the west. People in the coastal region have higher average income than others. As a result, HSBC (China) mostly build its banking network in the east and south areas, which are so called first-tier cities. Meanwhile, it has also expanded branches in some second-tier cities in the central area of China. 2. Economic Environment As an emerging market, China is developing at a very fast speed with continually growing Gross Domestic Product as well as high export surplus. However, in terms of global environment, the world still not recovers from the economic recession. The financial market in mainland has been impacted that the exchange rate of RMB has gone higher and higher, which has been result in the inflation. To better control the financial market, the interest rate has been increased to limit the cash flow in the market and personal saving rate goes up that people are encouraged to save money in banks rather than investing. Another economic factor putting effect on HBCS in China is the unemployment rate. China government devotes into keeping the unemployment rate low and stable, because once the rate rises sharply, this will destroy the harmony of the society. Consequently, HSBC (China) should take this factor into account to obtain trust and support from the local government. 3. Political Environment In China, banks are supervised by the China Banking Regulatory Commission. There are many barriers setting in front of those foreign banks in China, such as foreign banks are not permitted to establish a business of any scale in the mainland, since the Chinese legislations limit on how many local banking operations can lean on foreign banks. On the other hand, the new parties have held the power, which means new policies and new reform may come into being. Different policies and reform will significantly affect the existence of HSBC in China. With the improvement of the capital market, the financial environment will be deregulated and gain a more loosening environment. Moreover, foreign banks in China have to be charged tax, which will increase the cost and lower the profits of HSBC in mainland. As the compulsory education popularizing, more and more people think highly of the banking service. They become to have good knowledge to the banking items and are tied closely to those services. 4. Socio-cultural Environment Banks serve for peopleââ¬â¢s demand and need. Peopleââ¬â¢s attitude towards banks is influenced by the social-cultural environment. In China, customers are more conservative that they prefer saving money. Therefore, more emphasis should be put on the retail banking services in mainland. Recent years, with the impact of financial crisis, people are less trusting banks. Banks are seen as greedy organizations by the public, which was result from arbitrary banking charges. 5. Technological Environment Technological change can bring new style of business to organizations. It can change both the product and business way. Since the constant improvement of the Internet, HSBC has launched its online banking services in China. People can have an electronic account to check userââ¬â¢s balances and transactions, make transfer as well as pay bills. Simultaneously, doing business through the Internet not only save the time for customers, but also simplify the business process for HSBC so that they can cut large amount of cost. Furthermore, the development of the mobile phone also benefits the banking services. People can easily access to their account through the mobile Internet. Secondly, particular applications have been invented for mobile users to manipulate their banking service. For example, HSBC has its own applications which can be used for IOS (iphone) and Android operating systems. These applications are convenient to use and also help HSBC to saving labor as well as time cost. 6. Global Environment The global environment is somewhat cannot be controlled by the organizations itself. The global economy stays in a recession for a period of time and seems to be difficult to recover from it. The subsequent influences of the financial crisis affect the economy in China. HSBC (China) has earned less profit these years. Although the macro environment is not so optimistic, China is still the hugest potential market around the world. Besides China, there are still many emerging countries appear in the world, like India. In the future, HSBC (China) should pay attention to create more advantage competitiveness than those HSBC banks in other international regions. Reference Eternity in an hour. (2009).

The Properties And Uses Of Bricks Construction Essay
The Properties And Uses Of Bricks Construction Essay Brick is a core material that is commonly used to build the wall of a building. Clay bricks are the most common brick type. It is made from sand and clay and uniformly burnt at temperatures between 800à °C and 1200à °C. Surface finishes are sometimes applied, e.g. glazed bricks. Glazed bricks are still being produced in large quantity and can be obtained from major English brick manufacturers and suppliers. Calcium Silicate bricks is manufactured from sand-lime (calcium silicate). The bricks are pressed under great pressure and steamed in an autoclave. The bricks are smooth, fine textured and light in colour. The colour of the brick is produced from material source, composition and firing temperature. The size of bricks over time has changed considerably. Some early medieval bricks were 13 inches by 6 inches by 2 inches. By the late 15th century a brick 9.5 inches by 4.5 inches by 2 inches became the norm and a charter in 1571 stipulated bricks by the measurement of 9 inches by 4.5 inches by 2.25 inches. By the 18th century, 8.25 inches by 4 inches by 2.5 inches brick was introduced. Modern bricks are 8.5 inches by 4 inches by 2.5 inches which is following metrication translated to 215mm by 102.5mm by 65mm. Modern bricks are the bricks that are most used in buildings nowadays. 2.1.2 Defect of Size Poor material selection and preparation or underfiring is the main problem of oversized bricks. Undersized bricks are caused mainly by poor material preparation, faulty moulds and overfiring. 2.1.3 Defect of Shape There are many grounds which contribute to defects in shape. These are including poor preparation of moulds or moulding technique, faults in stacking, rough handling and uneven drying. If the bricks are considerably over burnt, incipient fusion takes place and the bricks, called burrs, will come out of the kiln or clamp and get stuck together. Burrs are suitable only for hardcore purposes. 2.1.4 Defects of Body Faults in the raw material can give rise to defects such as cracking, bloating and laminations. Cracking and warping of bricks, causing incipient weakness, may be due to exposure of green bricks to direct sunlight or rapid drying winds. Similar effects will be produced by putting green bricks into the kiln too soon. Large cracks maybe caused by rain getting onto hot bricks. 2.1.5 Defect of Appearance These defects are caused primarily by faulty wires in the case of wire-cut bricks. Dark spots are caused by the presence of unevenly distributed iron sulphide in the clay. 2.2 Types of Brickwork Defects 2.2.1 Introduction Most parts of a building are built using bricks. Nowadays, brickwork defects are commonly found in buildings. This problem is getting more serious as days go by. Brickwork defects may cause a lot of problems to the occupants. The main problem encountered in building with traditional outside bearing wall of brickwork and concrete inside bearing structure is caused by differences in the temperature and moisture-induced movement. Cracks may be discovered in walls and solutions have to be found to alleviate this problem. (Verhoef, 2001) Brickwork defect which occurs in buildings has a variety of reasons. This is perhaps not surprising when one considers the wide range of different bricks and techniques in the construction of building, differences in the construction sites and the varied occupational or owner usage of the completed building. Brickwork will deteriorate and decay if not properly maintained. Such deterioration can be caused by a number of factors and can take various forms. The main signs that the brickwork is afflicted are surface growth and staining, efflorescence, loosed brick becoming dislodged, cracks appear through the bricks or mortar and etc. (Moses Jenkins, 2007) In this sub chapter, the different types of the brickwork defect will be determined. This chapter gives an overview of various types of brickwork defects and understanding the brickwork defects. By identifying the different types of the brickwork defects, it will be easy for the occupants or owners to find out the causes of the defects and subsequently take the suitable remedy methods to address the problem. 2.2.2 Brick Wall Settlement Any movement in a structuralà brick wall will risk having the bond courses in the wall broken. Any movement in aà brick veneer wall which has broken or loosened the connections between the veneers to the underlying structure is potentially dangerous and risk collapsing the masonry. 2.2.3 Bulging Brick Wall This is likely to be a bond-brick or bond-course failure. This defect is potentially extremely dangerous and immediate action must be taken. If not, it will cause the building to suddenly collapse. 2.2.4 Cracks and Bulges in Brick Walls Frost and earth loading can push a below-grade brick foundation wall inwards. The wall is often bulged inwards as well as showing horizontal and step cracking and loose bricks will surface over the bulged area. The damage occurs from slightly above ground level to roughly the frost line. 2.2.5 Cracks and Loose Bricks Normally, crack and loose bricks are caused by frost, settlement, expansion, diagonal and stair-stepped. These defects often happen at building corners where the roof spillage is concentrated. 2.2.6 Loose Bricks and Missing or Lost Mortar This is the movement where the mortar is severely washed-out by roof spillage or other water movement against the foundation. Loose and lost bricks may also occur where wood blocks, originally set into a wall to permit nailing of interior components, is damaged by insects or decay. Similarly, if the wood joists are damaged and bent excessively or collapsed (insect damage, rot, fire), the collapsing joist can, as its in-wall end moves, damage the foundation or building wall. Fire cuts on wood joists in brick walls were intended to minimize this damage source by angling the end of the joist where it was set into the wall pocket. 2.2.7 Spalling Bricks Spalling is caused by water and frost, such as water leaking into a brick structure at any entry point: a crack, a brick which has lost its hard surface, or at openings by window and door penetrations. It is best to also beware of caulking bricks. 2.2.8 Exfoliating-Rust Damage to Bricks Masonry wall will have these defects when brick walls have been improperly caulked where caulking should have been omitted. The most common example of this defect is the damage that occurs to a brick wall when a steel lintel over a window or door is caulked tightly between the brick and the steel. Moisture penetrating the brick wall through cracks or mortar joints is trapped around the steel lintel. Rust developing on steel lintels has tremendous lifting power as the rusting exfoliating metal expands, sufficient to crack and damage bricks around the lintel. Improper Repair Mortarà on Brickwork During repair works, tuck pointing or re-pointing bricks can cause surface spalling of bricks if the mason uses a too hard mortar with high portland content or mortar on soft bricks in a climate exposed to freezing weather. The high portland content means that the mortar will be not only harder, but more waterproof than the surrounding bricks. Water trapped around the hard mortar can freeze leading to surface spalling of the bricks. This is particularly likely to be seen when a wall has been tuck pointed using hard high-portland mortar where originally a soft high-lime mortar was used and where the original bricks were soft. Salts on Brickwork Salts are a major cause of deterioration. Salt can enter bricks through contaminated water ingress. In coastal areas, salt can come from the sea and, in winter, the nearby application of road salt is a constant threat. Salt is damaging because it creates a steady expansion of crystals within the bricks. This can eventually force the structure of the brick apart. The source of salt can occur from within the bricks themselves or from the application of contaminated mortars or renders. Brick lined chimney flues are also vulnerable as sulphates can be introduced when flu gasses condense. This is a common defect where a chimney has been sealed without adequate ventilation. 2.2.11 Efflorescence on brickwork Efflorescence appears as a white powdery deposit on the brick. It is a phenomenon that soluble salt dissolved in water are carried, deposited and gradually accumulated on brick surfaces to form an unsightly scum. Without water, efflorescence cannot occur. The soluble salts may be originated from the raw material of bricks. But in most cases, efflorescence is caused by salts from the external sources such as ground water, contaminated atmosphere, mortar ingredients and other materials in contacts with the bricks. To minimize the risk, (it can never be completely avoided in brickwork exposed to weathering) the building detail should be designed, as far as is possible, to avoid saturation. In other words, good overhangs, copings and sills with drips, need to be considered. Efflorescence can be helped on its way by sponging down the wall with clean water (avoiding substantial wetting) or dry brushing with soft brushes. Any other treatment should be avoided as it may disfigure the bricks. à 2.2.12 Thermal Movement on Brickwork Every materials expand or contracts as the temperature of the material changes, typically expanding as its temperature increases and contracting as its temperature decreases. Different materials expand and contract at different rates when they undergo similar changes in their temperatures. Brick veneer can expand and contract approximately. When determining the expansion or contraction of a brick veneer, it is important to remember the effects of the sun on materials. The energy from the suns rays raises the temperature of a material well above the air temperature. On a day when the air temperature is 32à ° F, the energy from the sun can raise a walls temperature to above 100à ° F. 2.2.12.1 Thermal expansion failures in Structural or Veneer Brick Walls A separate factor that can cause very large movements and extensive damage to brick structures or brick veneer walls is the thermal expansion which occurs across a long or tall brick wall when that wall is heated by intense sun exposure. The photographs show significant thermal expansion damage in a long brick structure. Significant breaks and gapsà at vertical brick mortar joints due to thermal expansion and perhaps some frost and water damage. Figure1: Significant breaks in mortar Horizontal sliding breaksà in brick mortar joints,à exposing reinforcing wire to rust, exfoliation, and additional damage from those forces as the exfoliating wire produced still more pressure on the mortar joint. Figure2: Horizontal breaks in mortar Step crackingà following mortar joints near the building corners and where the wall movement was resisted by first story intersecting brick walls abutting at right angles the middle section of the long brick wall. Figure3: Step cracking in mortar Cracks and broken bricks at the intersections of brick walls and openings. Figure 4: Cracks and broken bricks (InspectApedia, 2007) 2.2.13 Moisture Movement on Brickwork Moisture affects all porous masonry materials, including bricks, mortars and concrete masonry units but in very different ways. These effects must be considered when a combination of these materials is used, such as when bricks rest on a concrete foundation, brick veneer units are used with block back up, and when brick and architectural concrete products are used in the same Wythe bands of precast concrete or architectural concrete block in a brick veneer. After their initial mixing or casting, mortar, poured-in-place concrete and concrete masonry units shrink as the curing of the Portland cement proceeds. This is an unavoidable consequence of the curing of concrete products and is accommodated in design. 2.2.14 Sulphate Attack on Brickwork Most ordinary clay bricks contain sulphates of sodium, magnesium or calcium. These salts are soluble in water, calcium sulphate being less soluble than the other two. Normally, these sulphates are seen as the harmless efflorescence which affect appearance only and need simply to be brushed away. In theory, most brick walls with mortars based on OPC (Ordinary Portland Cement) are liable to sulphate attack. The most vulnerable walls are earth-retaining walls and parapet walls but sulphate attack is a problem also on rendered, and facing brickwork. On rendered brickwork, sulphate attack is manifested by cracking of the rendering, the cracks being mainly horizontal and corresponding to the mortar joints below. The rendering may adhere quite well to the bricks early in the attack but areas are likely to become detached as the expansion of the underlying brickwork causes severance of the bond between the two materials. (Eldridge, 1976) 2.2.15 Lime Staining on Brickwork Lime staining occurs when calcium hydroxide is deposited on the face of brickwork. Lime staining will quickly absorb carbon dioxide from the air and becomes calcium carbonate. It is virtually insoluble and can only be removed by expert which is a costly treatment. The calcium hydroxide can come from three main sources: calcium hydroxide caused by the hydration of Portland cement from hydrated lime added to mortar from brickwork in contact with wet concrete 2.2.16 Porosity on Brick Porosity is an important characteristic of bricks. In contrast to other moulded or pre-cast building materials, the porosity of bricks is attributed to its fine capillaries. By virtue of the capillary effect, the rate of moisture transport in the brick is ten times faster than in other building materials. Moisture is released during day-time and re-absorbed during night-time. The ability to release and re-absorb moisture by capillary effect is one of the most useful properties of brick that helps to regulate the temperature and humidity of atmosphere in a building. This distinctive property makes bricks an admirable building material, particularly suitable for buildings in the tropics. On the other hand, all porous materials are susceptible to chemical attacks and liable to contamination from weathering agents like rain, running water and polluted air. 2.2.17 Crack in Brick Faces / Firecracks The finished appearance of clay brick can vary greatly; this is because it is dependent on clay and the manufacturing process. Some products contain cracks of varying degree (sometimes referred to as firecracks) as an inherent feature. Firecracks are usually visible on the product as delivered. However, firecracks can be masked by the texture and surface sands used in the manufacturing process which becomes visible after the bricks are laid as a result of natural weathering of exposed brickwork. 2.2.18 Dampness of the Brick Wall More or less permanent dampness showing more clearly on the internal wall surface from ground level up to a height of about 750mm, but may be higher in severe cases or if the outer face is covered with a non-porous finish. The decorations may be damp, blistered or discoloured, or, if dry, may have been pushed off the wall by a film or salts which will often be seen as a fluffy crystalline growth. The possible causes of dampness in the brick wall are lack of DPC (damp proof course), by-passing of the DPC, and failure of the DPC material. 2.2.19 Brick Growth and Expansion Gaps in Brickwork Bricks undergo long-term permanent expansion over time. This expansion continues for the life of the brick, but the majority of the growth occurs early in its life. Most general purpose bricks have a coefficient of expansion in the range of 0.5-1.5mm/m (millimeters per meter) over fifteen years. Designers can use the values of the coefficient of expansion to accommodate for the growth of bricks by the size and spacing of the control joints. The provision of control gaps or articulation joints between parts of the structure during construction will accommodate movements within the structure over time. Numerous sources of movement exist and include: The change in size of building materials with temperature, loading conditions and moisture content The differential change in size of building materials (for example, cement products shrink over time, whilst clay bricks expand slowly over time) Foundation and footings movement Frame movement Frame shortening Temperature movement Internal horizontal and vertical movement 2.3 Causes of the brickwork defects 2.3.1 Introduction Brickworks are used primarily in the construction of walls. To construct the brick wall required many skills, design, experience, selection of material, and technique. Lack of all expertise may cause the brickwork defects or failure of the building. The defects that occur in brickwork maybe the result of inherent faults, deficiencies in production, design, materials or workmanship, and attack by environmental agents. After the brickwork has been constructed, it maybe meets of various requirements, climate, loading, and occupational in use. It is not surprising that defects happened or occurs frequently. In this sub chapter, the causes of the brickwork defects will be list out. To find out the actual causes of the brickwork defects will be easily for the occupational to take the right remedies immediately and reduces the brickwork defects happen. 2.3.2 Selection of bricks The choice of bricks is often influenced by the price but the quality required must also be carefully considered in order to avoid defects developing during the service life of the material. Therefore, the selection of suitable bricks for any particular purpose has often to be a trade-off between appearance and durability requirements on the one hand, and cost on the other. This is not always possible to assess the quality of bricks by the colour, variability of colour of bricks of the same source and method of production can often be an indication of strength and durability variations. 2.3.3 Storage of bricks Bricks on site are rarely kept under adequate cover. Defects in the bricks resulting from the lack of adequate protection on the site are rarely apparent before use. However, bad weather conditions can be detrimental to bricks in that saturation by rain can be responsible for both subsequent efflorescence and decoration defects. 2.3.4 Soluble Salts in Bricks Under burnt bricks contain a high salt content. The salts come from the raw clay from which the bricks are made, or are formed in the burning process. Most clay bricks contain some soluble salts, but the types and amounts vary appreciably. The effect of the soluble salts on both efflorescence and the more serious problem of disintegration of bricks themselves are largely governed by the strength and pores structure of the bricks. 2.3.5 Sulphate attack Sulphates are salts which are naturally present in industrial waste, gypsum product, clay bricks, flue condensates and in some ground waters. In persistently damp conditions, sulphate will react slowly with tricalcium aluminate forming a compound called calcium sulphoaluminate. This reaction causes the cement mortar or render of the brickwork to expend and eventually disintegrate. 2.3.6 Solar Radiation While drying out of soil by trees is the most common reason for cracking in brickwork, some clay are also very susceptible to drying out by direct solar radiation. The northern facing wall is the most likely to be affected and stepped diagonal cracking is the most common symptom, usually occurring at the north east and north west corner of the building. (Loveder, 2000) 2.3.7 Migration of moisture The movement of moisture beneath a building can produce the phenomenon known as long term dome and saucer effect. The dome effect is a slow heaving of the soil caused by movement of moisture from the perimeter of the house to its centre, and the saucer effect is moisture moving in the opposite direction, from the centre towards the perimeter. The dome effect causes the walls to tilt outwards and the restraining influence of the roof produces horizontal cracks on the outside wall. These will be wider on the outside surface rather than the inner. 2.3.8 Planting of tree Some of the brickwork defects may cause by big trees roots that plant nearby the building area. When planning to plant trees, the idea to be considering is the strength of the footings under the house. If lack of strength, the roots of the trees maybe grow into the ground under the building and cause the brick wall settlement and cracking. 2.3.9 Uneven settlement of foundations Where a particular heavy load is placed on the foundation such as a large column, movement may occur as moisture is squeezed out of the soil or the soil readjusts itself. This consolidation will stop when the soil has finally compacted enough to support the load. Brick wall or masonry wall may crack which may result from movement during compaction. 2.3.10 Excessive vibration Damage caused by vibration from earth tremors, heavy traffic or pile driving is fairly rare, however if the vibration is great enough to actually cause the foundation to move, brickwork cracking or defect can occur. The crack will show up irregularly if the sources of the vibration cannot be removed. (Loveder, 2000) 2.3.11 Additional building Building an addition building onto a house or add more storey of houses can impose a load intensity on the soil different that which is there already and so cause differential settlement. Even if the loading intensities are similar, the difference in time between when the two settlements occurred can be enough to create the brick wall cracks. 2.3.12 Approach of design Design of brick wall is very important. The designer must have the knowledge about the brick experience in chosen the types of brick to be used. The designer must be fully aware of the clients needs. Defects often occur because of a lack of understanding of the different types of bricks and the method of construct the brick wall. 2.3.13 Lack experience of worker Workers in the masonry construction is not in strict accordance with the construction and standards, masonry mortar is not full, especially in vertical mortar joints are not full, and even produce dense seam, seam permeability. In addition, the dry brick on the wall, mortar in the brick water was absorbed, causing low strength of mortar, brick and mortar separation, so that the overall stiffness of masonry fell, gray mortar joints crack. 2.3.14 Overloading Cracks of brickwork may result from overloading of the ground on which the building rests, or of the building itself or parts of it. Releasing the load does not necessary allow the masonry wall to revert to its original state since the overloading may have been partially accommodated by a permanent compaction of the bricks. The forces responsible for the overloading may be of external origin, such as excessive wind, or may be internal, such as those arising from the installation of excessively heavy equipment for which the masonry wall was not designed. A change of occupational may have same results. 2.3.15 Lack of maintenance Maintenance must be taken for all the building to minimize the cost of repair work for seriously defects happen. Lack of maintenance will make a small cracks or defects on brickwork change to more serious and serious. 2.3.16 Improper soil analysis and preparation When a builder chooses an area of land to build on, it is important to do some sort of soil analysis and preparation. The analysis will provide the developer and/or builder with enough information to choose the adequate soil preparation and construction strategy that should be used to develop the land. Improper soil analysis and preparations can be very damaging to a housing development. For example, a builder can discover that the land soil is made up of expansive soil. If this is the case, houses need to have a foundation that will be able to support the changing pressure and consistency of the soil. This is because expansive soil will swell when wet and then shrink once it dries. If one builds on this type of soil and is not aware of it, there will inevitably be issues to handle. There will be crack in the brick wall or masonry wall. The repair of this is very costly and very intrusive. Unfortunately, the reality is improper soil analysis and preparations happen all the time. 2.3.17 Negligence of construction Negligent construction is an unfortunately common occurrence. A builder has to be very careful when choosing a contractor or subcontractor. A builder will sometimes use one contactor for various projects. A contractor may have skills to install floor tiles but not the know how to build a brick wall. The responsibility can fall on several parties when there is a defect, and thats up to your attorney to determine. 2.3.18 Movement of the ground Mining subsidence, landslips, earthquakes, or moisture changes of shrinkable clay soil may cause the movement of the ground. The brick wall of the building will be crack because the wall of building has become displaced from the rest without any change in actual size of the materials. In theory, this is possible to reconnect the displace parts to bring the building back to its original condition but in practice this seldom can be done. 2.3.19 Acid rain Acid rain is precipitation that is much more acidic than normal rainfall, and the acid rain is usually caused by pollution such as sulfur and nitrogen emissions. Several different mechanisms are operant in the deterioration of brick masonry through the action of acid rain. The bricks are susceptible to acid rain through the selective dissolution of their glassy phase. The mortar is affected mainly by the reaction of the calcareous components. The soluble salts resulting from these reactions, in solution with rain water or condensed moisture, will migrate through the porous matrix of the masonry. In the places where the water evaporates the salts will be deposited. Repeated dissolution and re-crystallization of these salts leads to the mechanical disruption of the masonry structure. Since the salts will concentrate in the more porous material, either the brick or the mortar will be more seriously affected, depending on their relative porosity. 2.3.20 Environment Two aspects of the environment have been considerably which is wind and temperature. This is because they cause loading to be applied to the structure. The strong wind may cause the brick wall or the whole building move, this may cause cracking to the part of the building. The high temperature applied to the brickwork may cause spalling and brick prolong to high temperature can lead to surface vitrification. (Swoden, 1990) Table 1: Causes of the brickwork defect and the preventive method to avoid it happen No. Causes of brickwork defects Preventive method 1. Selection of bricks Use the bricks that are strength and durability 2 Storage of bricks Keep the bricks under dry place 3. Soluble Salts in Bricks Use the bricks that are less contain of soluble salts 4. Sulphate attack Ensuring the wall does not get and stay in unduly wetted. Use cement low in tricalcium aluminate 5. Solar radiation Make sure trees plant far away from the brick wall 6. Migration of moisture Use of damp proof course below the brick wall 7. Planting of tree Make sure there have no big tree nearby the brick wall 8. Uneven settlement of foundations Make sure the foundation is strong enough 9. Excessive vibration Make sure the foundation is strong enough 10. Additional building Do not build additional building of brick wall after a long period finish of brick wall 11. Approach of design Designer must be experienced and knowledgeable 12. Unskilled worker Make sure the brick wall is built by skilled worker 13. Overloading Brick wall must be design according to building use 14. Lack of maintenance Must me maintenance the brickwork annually 15. Improper soil analysis and preparation Check the soil properly and make sure the design of brick wall is strong enough 16. Negligence of construction Careful when choose the contractor 17. Movement of the ground Make sure the foundation is strong enough 18. Acid rain Wash or clean the brickwork before it decay or surface treatment 19. Environment Use the brick that are strength and durability 2.4 Remedies method of the brickwork defects in building 2.4.1 Introduction As known early, brickwork is one of the largest parts of most of the building. The strength, stability, and durability of brickwork are very important. If lack of all those factor, the brick wall or masonry wall maybe fall down or collapse suddenly. If the brickwork occurs any cracking or defects, the right method of remedies must be taken immediately. This is to ensure that the occupational or owner use the building under safety and healthy purposes. Brickwork will deteriorate and decay if not properly maintained. Such deterioration can be caused by a number of factors and can take various forms. The main signs that brickwork is suffering are surface growth and staining, efflorescence, loosed brick becoming dislodged, crack appears throw the bricks or mortar and etc. So, the right remedy must be taken to ensure the brickwork do not decay and deteriorate. (Moses Jenkins, 2007) In this sub chapter, the remedies method for various types of defects will be list out. This is to avoid the brickwork defect getting serious in building in construction industry. The defects of brickwork must be repair immediately, if not the defects will be more serious. For example, cracking can be due to expansion or shrinkage the clay brickwork itself. 2.4.2 Remedies of efflorescence Efflorescence can be minimized by laying dry bricks and by speeding up the drying process after the bricks have been laid by providing good ventilation. The salts that cause efflorescence are soluble in water. Hosing with water will cause the salts to dissolve and be re-absorbed into the brickwork, and then reappear when the brick wall dries out again. Acid or alkaline treatments are not recommended as they increase the salt content of the wall. The best method is simply brush off the deposit with a stiff dry bristle brush after the wall has dried out. Then sponge the surface with a damp synthetic chamois or high suction sponge. Use very little water and rinse sponge frequently in fresh water. 2.4.3 Sand-Blasted Bricksà Which have been cleaned of old paint, algae, or stains using high pressure sand blasting or possibly even v

Applications of 3D Printing Technology
Applications of 3D Printing Technology Lara Soueid Abstract What if we could simply print a bone when we have a shattered one? This has now become possible due to the three-dimensional (3D) printing innovation. 3D technology In our days, technology is advancing at a very rapid pace. Out of the many recent innovations is the three dimensional (3D) technology. It has been exploited in various industries such as the movie production, television, computers, and printers industries. This technology has just recently been introduced into the medical field, more specifically, the 3D printers (Walker A, 2013). There are various medical applications of the 3D printers; some of these are to print prosthetic limbs, and implants. So far, there are many advantages, yet also a few disadvantages to the latter. The three dimensional technology relies on the fact that we see things in 3D by our eyes in our daily, that is we visualize objects by their width, length and depth (3deyehealth.org June12, 2014). The process by which our eyes perceive three dimensional images from two highly similar overlaid images was first described by Sir Charles Wheatstone in 1838 (Sniderman Z, 2011). Another name for 3D is stereoscopy; it explains how our eyes and our brain create an impression of a third dimension. Our eyes are approximately 50-75mm apart, hence each eye perceives a slightly different image which the brain merges using some high powered geometry which is basically the 3D concept (Sniderman Z, 2011). Modern 3D technology is trying to replicate what the brain does to merge the images. This technology tricks the brain in order to perceive two different images from the same source (Wong KV, Hernandez A, 2012).There are multiple uses of the 3D technology, mainly architecture, the movie industry, printing and gaming (Sniderman Z, 2011). 3D printing has recently been on the rise, these machines are able to make anything from simple materials. By doing so they replace traditional factory production lines and make everything in life much easier, a person can easily print a cup or chair, or even a house (Walker A, 2013). 3D printing technologies There are various 3D printing technologies being used, namely selective laser sintering (SLS), fused deposition modeling (FDM) and stereolithography (SLA) (Pravas VS, 2013). The SLS printers use a very powerful laser in order to heat and bind the printing material into the required 3D object by scanning the cross sections generated from the 3D digital file. When each cross section is scanned, the powder bed is automatically lowered one layer thickness and new material is placed above it. The object is surrounded and supported by the same powder it is made from. This process is repeated until the object is complete (Deckard C, Beaman J, Bourell D, 2012). Figure 1: Selective Laser Sintering process, Martello.co.uk, June 12, 2014. The second type is the FDM printers, these printers use a process by which thick filaments are melted and forced through a heated nozzle which forms the object. Once the first layer is formed, the base is lowered and the second layer begins forming and fusing with the first layer. However unlike the SLS, these printers require two different materials, the thick filaments in order to make the object and a support material which surrounds and supports the object while it is being made (Deckard et al., 2012). Figure 2: Fused Deposition Modeling process, 3dprinterplans.info, June 12, 2014. The last type of printers are the SLA printers, these printers use liquid photopolymer resin as the basic material. Photopolymers are materials that are sensitive to light, once exposed to ultraviolet (UV) light, they will immediately harden. The UV laser beam traces a cross section of the object onto the resin, which immediately curs when it is exposed to the light (3ders.org, March 14, 2013). The base then lowers and the top is coated with more resin which again gets exposed to UV light hence hardens and mends to the lower layer. This process is repeated until the object is completed (Deckard et al., 2012). Figure 3: Stereolithography printing process. Pravas VS, 2013. The latter are all additive manufacturing processes which require the help of computers. The 3D object blueprint to be printed must first be modeled three dimensionally on a computer software, most commonly using the computer aided design (CAD) software. Magnetic Resonance Imaging (MRI), as well as computed tomography (CT) scan can also be used (Pravas VS, 2013). The CAD file is converted into a Standard Tessellation Language (STL) file which transforms the geometry into small triangles, a header, or a triplet list of x, y and z coordinates. This file is then sliced into cross sections exactly as the printer will print, this file is called a G-Code file which can now be directly interpreted by the printer (Wong KV, Hernandez A, 2012). Table 1: Comparison of 3D printing processes. (3dprinteplans.info, June 12, 2014) There are various applications to 3D printing, such as architecture, automotive, engineering, fashion and numerous others. However the most important applications are the use of 3D printers in medicine to produce implants and prosthetics (3dprinterplans.info, 2014, June 12). Throughout the world, poverty is increasing and living costs as well as the medical costs are also increasing. A prosthetic arm for an amputee would cost on average $3,000 to $30,000 depending on the patientââ¬â¢s age, activities, profession and his health hence making it impossible for anyone except the rich population to be able to buy a prosthetic arm or foot (Turner R, 2009). Lucky for the third world countries people, as well as the middle class people, a novel technology will solve the latter issue. The innovation of the 3D printers has and will change many lives. The process of printing a prosthetic hand relies on the FDM technology. The material used is most often high-performance thermoplastics which are biocompatible, and the average price of a 3D printed prosthetic arm is about $200 (Stratasys Ltd, 2014, June 12). The 3D production of prosthetics is not only cheaper, faster and more practical, it is a revolution which allows every amputee of living a normal life again. The main problem in producing a prosthetic arm or leg is the need of a blueprint or prototype. The patientââ¬â¢s limb is scanned using a CT scanner or a laser-based scanner, this image is then converted into a G-Code file which can be directly printed by the printer in order to produce a new very similar limb (Andrews TM, 2013). There was also a problem of printing the socket (the part that will be attached to the amputated limb) accurately (Stratasys Ltd, 2014, June 12). However this has all been solved by the open end prototypes and blueprints available for everyone to use (Stratasys Ltd, 2014, June 12). Sydney Kendall is a thirteen year old girl from St.Louis, her right arm was amputated due to a boating accident when she was six years old. Senior students in the Washington University in St.Louis studying biomedical engineering printed a prosthetic arm using plastic as the raw material for Sydney. The total cost was only $200. This prosthetic is powered by a battery and controlled by an accelerometer allowing her to move her prosthetic fingers (Washington University in St.Louis Newsroom [WUSTL], 2014). The most recent 3D printed prosthetic hand is the ââ¬Å"Flexy-handâ⬠, produced by Gyrobot Ltd by Steve Wood. This prosthetic arm looks very similar to a natural human hand and it operates like one too. He has used Filaflex flexible filaments which form tendons that are activated by a motor that allows the prosthetic hand to operate very much like a normal human hand. (Krassenstein E, 2014) Maxillofacial prosthetics are also being produced by 3D printers. Usually the conventional maxillofacial prosthetics production requires that an impression from the trauma site is taken, then a plaster positive should be formed, a mould should be made and the specific shape must be carved in the wax, lastly it must be casted in silicone. This is very laborious, time consuming and expensive to be done. Using the 3D technology, the patientââ¬â¢s face should be 3D-scanned, this image will then be converted to the appropriate file to print the perfectly fitting prosthetic part (Wainwright O, 2014, June 12). 3D-printed titanium shoulder and collar bone implants were successfully implanted into three different patients suffering from cancerous bone tumors in Xiââ¬â¢an, China. The bone design was printed using the selective laser sintering technique which fused titatium powder into the exact shape of the patientââ¬â¢s bone. The implants do not cause infections and are very durable and resistant (Zeng C, 2014). This has also been done in the United Kingdom for a cancer patient (Moore G, 2014). Soon, 3D printing will replace manufacturing industries and save millions of lives. Various kinds of implants such as knee caps, skulls, auditory devices, and jaw bones have already been produced by a 3D printer and have successfully been implanted. There are 2 astonishing cases whose patients have been given a second chance to live due to 3D printers. The first case is Stephen Power, he is a survivor of a motorbike accident that shattered his face. His face was reconstructed at Morrison Hospital in Swansea, however, his entire face was reconstructed using custom made 3D printed models, plates, implants and guides. The surgical team used CT scans to create symmetrical 3D models of Powerââ¬â¢s skull which they then printed, implanted, and held in place using a printed titanium implant (Griffith H, 2014). The second case is of a 22 year old woman from the Netherlands who had her skull replaced by a 3D printed skull implant. She suffered from a chronic bone disorder which increases the thickness of her skull, neurosurgeons at the University Medical Centre Utrecht pr inted a perfectly fitting durable plastic skull implant (University Medical Center Utrecht [UMCU] research news, 2014). Dr.Bon Verweij of the UMCU says: ââ¬Å"Its now three months after the operation. The patient has fully regained her vision, she has no more complaints, shes gone back to work and there are almost no traces that she had any surgery at all. The printing process of prosthetics and implants requires hours to a few days maximum. There arenââ¬â¢t any documented reactions to the prosthesis or implants, they are cheaper, more durable, more resistant, less laborious and they are FDA approved (Pollack SK, Coburn J, 2013). However the main disadvantage is the expensive price of the printer and the designing program. Most prototypes are open ended and available online for modification and many hospitals and universities now have 3D printers (Stratasys Ltd, 2014, June 12). With the increasing popularity and availability of 3D printers, we are finally ableto create prosthetics and implants under $1000. Even though alternative production methods are present, they are not available to the people that need them most due to their high cost.

Philip Larkin - A Voice of Pain for This Century Essay -- Biography Bi
Philip Larkin - A Voice of Pain for This Century On August 9, 1922, the poet Philip Larkin was born in the town of Coventry in England (Thwaite, Letters xvii). After graduating St. Johnââ¬â¢s College in Oxford in 1943 with a First Class degree, he worked at both the University College of Leicester and Queenââ¬â¢s College at Belfast before finally settling down at the University of Hull as Librarian in 1955 (Thwaite, Letters xviii). That same year, with the publication of his collection The Less Decieved, he "began to be recognized" (Thwaite, "Introduction" xv). His popularity continued to grow thereafter, and over the next twenty years amongst many awards and honorary doctorates he published two more highly acclaimed books of poetry, The Whitsun Weddings in 1964 and High Windows in 1974 (Thwaite, "Introduction" xvi). In 1984 he was offered the ultimate title of Poet Laureate, which he declined in part because of "shyness" and in part because of the "conviction that his poetry had deserted him" (Motion 510). With the words "I am going to the inevitable," he died a year later on Monday, December 2, 1985 (Motion 521). During his stay at Oxford, Larkin was a member of a group called "the Movement, its revolt being against rhetorical excess or cosmic portentousness" (Ellmann and Oââ¬â¢Clair 579). He held disdain for the intricate poetic approach of Eliot and Pound in which "first of all you have to be terribly educated, you have to read everything to know these things, and secondly youââ¬â¢ve got somehow to work them in to show that you are working them in" (Ellmann and Oââ¬â¢Clair 579). Larkin instead pursued "a more even-tempered, conversational idiom, more accurate than magniloquent" (Ellmann and Oââ¬â¢Clair 579). But this "even-temperament" did n... ... who reside in the twentieth-century and stand as perennial expressions of not only his but of any individualââ¬â¢s mind. While the people of the world poise anxiously on the verge of a new millenium, only poets of his caliber will be remembered as having the sensitivity to capture the emotional need of this generation that will surely pass on to the next.

Prescription narcotics Essay -- essays research papers
The Need for Restrictions ââ¬Å"Why there should be stricter regulations on the availability of prescription narcoticsâ⬠Despite efforts to decrease the number of deaths and overdoses related to narcotic medications, such as OxyContin, and minimize the number of people illegally obtaining them, the measures that the DEA (Drug Enforcement Administration) in specific are taking are not enough. The literal definition of a narcotic is a drug that produces numbness or stupor; often taken for pleasure or to reduce pain; extensive use can lead to addiction. Narcotics are normally prescription medications that are given to patients to help ease the constant pain cause by cancer or other long term illnesses. ââ¬Å"When one in 10 high school seniorââ¬â¢s reports abusing prescription painkillers, the DEA is obligated to protect our children and the public safetyâ⬠says Karen P. Tandy administrator of the DEA(1). Tandy is saying that when the abuse of prescription pain medication is taking over that many students the DEA must step in for the sake of future generations. There is a long process that not many average Americans know about that all pharmaceutical products, especially addictive medications have to go through before they reach home medicine cabinets. This process is called ââ¬Å"Diversionâ⬠. It is an important chain like process that the DEA (Drug Enforcement Administration) have been using for years to look at where highly addictive drugs, like OxyContin, go and who they come into contact with. From the pharmaceutical company that literally make the product, to the drug wholesalers that sell the product, and then into the hands of doctors and pharmacies who prescri be and distribute the medications. The purpose of diversion is to take the information and look for certain situations where drugs were lost, stolen, or illegally distributed and give proper punishment to those people. The problem of abusing prescription narcotics became noticeably out of control in the 1990ââ¬â¢s. The problem lies in the fact that it is 2005 and the numbers of overdoses and deaths have been and are still rising at astonishing rates. An argument however, that many people have about advancing restrictions on OxyContin and other schedule 2 narcotics is that the needed process that one might have to go through in order to properly obtain the drug would be an ââ¬Ëinvasion of privacy.â⬠Some believe that reportin... ...rsâ⬠¦the number of patients in motor vehicle crashes who are ââ¬Ëmethadone impaired,ââ¬â¢Ã¢â¬ says John H. Burton, MD Medical Director for Maine Emergency Medical Services.(3) To think that the problem of abusing any kind of drug would just disappear with one solution is naive and absurdly optimistic. However, to think that all the DEA is doing right now to prevent harmfully addictive and destructive medications is enough is plain ignorant. The DEA has made substantial progress toward making OxyContin and other prescribed narcotics less available for abusers. But first hand accounts and shocking statistics prove that these measures are clearly not enough. It is true and will always be true that free will is a legitimate part of this equation. The abuse of any kind of drug is almost guaranteed to be present at all times no matter how hard the government tries. If a person wants it they will have it. The fact also remains that people with addictions cannot control themselves or their addictions, thatââ¬â¢s why it is called an addiction. Therefore making it the partial obligation of the DEA and the government to not only recognize this desperate need for r estrictions but do something more about it.
