Five-Year Career Development Paper Essay Example for Free

Five-Year Career Development Paper Essay Every year millions of college students worldwide graduate from college in hopes of obtaining a position in their career field of choice; however a lot of these students do not have a plan of action to actually help them find their career and achieve their goals. So much emphasis is put on college graduates going out and finding a job, but little focus is put on helping them find a career. A five year career plan is a road map that allows for progress tracking, and development of solutions or alternate courses of action (Crump, 2009). From personal experience I have realized that the chances of achieving my personal and career goals are increased of I actually write them out as a plan. In this paper I will discuss my career goals and objectives, my current knowledge and skills that I currently possess in my future career, the steps that I will take in order to meet my career goals, and any possible barriers that may present themselves in the path to me completing these goals. Currently I am a front desk clerk and personal trainer at Fitness Systems, a privately owned fitness center in South Sacramento. Since it is a small business and only consists of five employees, chances of promoting within the business are small. However I have used my experience from working the front counter and interacting with members of the gym, to help promote my presence of being a trainer. Also, working at Fitness Systems has allowed me to observe the procedures and responsibilities that it takes to run a successful business. Statistics show that most small businesses will fail in between 1-3 years from the initial startup time; therefore I am trying to absorb as much information as possible so that I dont fall into the same category. In order to manage a successful career it is important to develop an exceptional method of thinking strategically and exceptional execution skills. Building upon my skills in these areas will help me to achieve my long term goals. In all organizations, it is important that management sets goals for employees in accordance with the goals of the organization. When I open my fitness center, one of the main things that I want to stress among my employees (trainers), is strong communication skills. If management and staff arent on the same page, there will be an abundance of errors within  the organization. If certain skills are lacking within employees, it is the responsibility of management to identify these weaknesses and find a resolution such as training, to solve the issues. As a way to help kick start my five year career development plan, I have put together a list of some of my short term and long term career goals. My short term goals include improving upon my current skills as a personal trainer and gain experience in specific areas such as nutrition, so that I will be prepared to take on the role of being the owner of my own Personal Training Company. My personal short term goals include the following: increasing my knowledge in anatomy, improve upon my ability to map out an effective workout plan for clients, improve upon my communication skills, obtain my business degree in management, network with other local personal trainers, and gain more hands on personal training experience by recruiting more clients. My personal long term career goal is open a private fitness center that enables clients and their trainers to schedule one on one sessions in the center without having to worry about the crowds that usually plague commercial fitness centers. This goal will be achieved by the summer of 2012. My plan is to continue being a part time trainer for now, graduate with my BS in Business Management, enter and complete the MBA marketing program at the University of Phoenix, and then work on opening up my fitness center. Owning a successful business requires that you build strong relationships with your clients/customers, their families, and the surrounding communities. Maintaining a positive stance and reputation in the community that you serve, determines if youre company will be successful. In order to promote myself within the community, I have created business cards that describe the service that I provide and my contact information. I have also spoken to the founder and CEO (Plashette Robinson), of a local journal called the Sacramento Cultural Hub. Sacramento Cultural Hub is a Sacramento based journal that spotlights small businesses owned by minorities in Northern California. Ms. Robinson has agreed to post a small feature about  me in her journal. This feature will include a photo of me, current attributions to the community, my educational background, my career field of choice, and my opinion on different health/fitness related issues that are plaguing our society and communities. I feel that Sacramento Cultural Hub, along with my personal efforts, will help give me the exposure that I need to earn a good reputation within the community. As I mentioned earlier in this writing, actually mapping out a plan will help increase the chances of all objectives and goals being met. Below is a chart that displays my Five-Year Career Development plan on a year-to-year basis. Intermediate Steps Over the Next Five Years to Reach My GoalFor MeFor my supervisor/others who will support meYear OneFocus on school and earn my degree in Business Management by March 2010.Feedback from my peers and professors. Year TwoComplete the MBA Marketing program at UOP. Attend courses for first time business owners and begin looking for high traffic locations for my Fitness Center.

N/A*Five-Year Career Plan Chart template retrieved from: mpiweb.orgRegardless of how well thought out a plan may be, there is always some kind of temporary barrier that may be encountered. In relation to my career plan, two potential barriers that I predict may take place are time management issues between my professional and personal life and a further downturn in our nations economy. Both of these issues can definitely cause a change in the objectives and goals for my business. However, the matter of time management can easily be tweaked if any issues shall arise and any issues in relation to the economy will have to be solved on a day to day basis. Both of the barriers mentioned above are vital, but they are issues that all small business ownerss struggle and deal with. In conclusion, I have shared my five-year career development plan. This plan will help assist me in achieving my career goals and at the same time help me in meeting some of my personal goals as well. Creating a development plan will assist in maximizing the potentials of an individual in the workplace. A career development plan not only helps to keep me motivated and focused; it also helps in providing the confident feeling that will in turn help me take charge of my career.

Internet Censorship Essay -- Short Stories Technology Papers

Internet Censorship Max walks into the classroom five minutes late, his shirt untucked and hardly buttoned. He sits down a few desks away from Ben who had arrived five minutes early and was waiting patiently for class to start. Although the boys seemed completely opposite, Ben the more conservative and shy one, while Max, a little more rebellious and mischievous, they were best friends and did most everything together. A few weeks into their fifth grade year, the teacher announced that they would begin doing reports on their favorite animal. They knew that this was the first year they were able to use the computer lab in the library and the idea of being able to use the internet excited them. Mrs. Howard sent the class to the library for the next period so they could start researching information about their animals. Some of the kids wandered around the second floor looking for books pertaining to their projects and some chose to start their search on the internet. Max and Ben went to the computer lab, found an open computer and began to browse different search engines looking for information about their animals. Max became bored with this idea and began searching sites of his own interest. Finally he found one that appealed most to him. â€Å"Hey Ben come look at this!† Max said. â€Å"What is it?† Ben rolled his chair over to Max’s computer screen and looked at what Max had pulled up. â€Å"Max, you’re going to get in trouble, you better get that off there.† â€Å"No way man, this is awesome†¦let’s look at some more.† The site that Max had clicked on was a pornographic web page containing many obscene pictures Aof naked women and other adult content. Although Ben felt unco... ...e room they see their 7 year old daughter Katie playing around on the computer. They noticed that the screen had a big caption in the middle stating that the site wasn’t able to be accessed. Curious to know what the blocked site was, Mr. Miller clicked the â€Å"Back† button and saw â€Å"Take a Wild Ride in Barbie Land† in big purple letters. Right away he knew that Barbie wasn’t referring to the actual doll and was relieved to know his daughter would never get to see the contents of that site. He looked at his wife and sighed, â€Å"Thank God we decided to install NetNanny onto our computer. You never know what these kids could have gotten into if we weren’t around.† â€Å"I agree honey. Now all we have to do is convince all those other parents and teachers to feel the same way about installing them at school. Hopefully we can get our plan to work.†

Analyzing Managerial Decisions: Eastman Kodak

With the slogan â€Å"you press the button, we will do the rest†, George Eastman (a high school dropout) put the very first simple camera into the hands of a world of consumers in 1888 (â€Å"History of Kodak,† n. d. , para. 1). For many years, Eastman Kodak was virtually the only film manufacturer around so they had a monopoly in film production. Kodak was able to control the timing for introducing new products into the market and was able to make changes due to customer demand. Until the early 1980’s, Kodak owned the film production market with very little competition.This suddenly changed when Fuji Corporation and many other generic store brands began producing high quality film as well (Brickley, Smith, & Zimmerman, 2009, p. 358). Technological advances, robotics, new design capabilities and better communications made it possible for the other companies to bring new products to the market in much less time. It was now months instead of years (Brickley et al. , 2009, p. 358). Film and related products became more readily available, resulting in a more competitive film production industry. Kodak’s monopoly was gone.This caused Eastman Kodak to make changes to its organization architecture in 1984; the design of the current organization architecture no longer fit the business environment for the film industry. One of the largest factors to motivate Eastman Kodak to make these changes, were increased competition and decreased market share. The stock price of Eastman Kodak went from $85 a share in 1982 to just over $71 in 1984. This is a drop of 16% in their stock price (Brickley et al. , 2009, p. 358). When compared to the increases in stock for the other companies in this market as a whole, the decrease was disturbing.Kodak made some rapid and unbalanced changes to its architecture, in order that they might regain some of the market share it lost. While making changes to one section of the company, they did not coordinate the change s to the other sections. In 1984, Kodak decentralized the organization by restructuring and changing its decision making process. â€Å"The restructure created 17 new business units†. These new business units had profit–and-loss responsibilities, and the corresponding managers were given the responsibility to decide on new products, pricing and other important policies (Brickley et al., 2009, p. 359). Unfortunately the result of this major organizational architecture, had a very small impact on the companies plan to regain its market share and profits. In reaction to the lack of impact, Eastman Kodak implemented the Management Annual Performance Plan (MAPP). This was to be the new performance-evaluation and reward system. There are many types of Management Annual Performance Plans ( The government Performance Results Act of 1993 requires each state agency to develop and publish an Annual Performance Plan (â€Å"Annual Plans,† 2003, para. 14)).The company felt by changing the methods of rewarding individual and business units, it would help them to be more innovative and more responsive to the customers’ needs and demands (Brickley et al. , 2009, p. 359). And again, this change was a mistake and unfortunately it did not have the affect Kodak thought that it would. The new Performance Evaluation System did not motivate the employees. When changing organizational architecture, it is extremely important to remember that the three legs of the stool (or the three components) of organizational architecture are interdependent and need to be coordinated (Brickley et al., 2009, p. 350-1).Kodak should have designed it with the three following characteristics in mind: 1) assignment of decision rights, 2) methods of rewarding individuals, and 3) structure of systems to evaluate the performance of both individuals and business units (Brickley et al. , 2009, p. 341). This left Kodak’s â€Å"three legged stool† unbalanced. In short, t he company did not implement a rewards method and performance evaluation system at the same time it began changing the assignment of decision rights. When one component is changed, the other components should be changed too.Kodak could have improved the effectiveness of the change in organizational architecture by holding employees accountable while also implementing a decentralized decision making approach. Kodak was set in its ways for a long time and when Fuji and the other companies came along with the advanced technologies; it did not know how to make these changes in the most effective and efficient way possible. Finally, I believe they should have fired the CEO earlier, he was definitely not thinking along the same lines with the market performance and changing industry.When he discovered the three legged stool was not balanced it was too late. By firing the CEO this may have provided the â€Å"shake up† that management needed to get the company going in the right dire ction. â€Å"An interesting view in economics asserts that the foundations for behavioral assumptions such as profit or utility maximization at an individual level or behavior in accordance with Nash equilibrium at the strategic level should be found in evolutionary selection against those who do not behave as assumed. This view, could be called economic Darwinism† (Sloth & Whitta-Jacobsen, 2005, para. 2).This example perfectly illustrates the concept of economic Darwinism, especially from the perspective of â€Å"survival of the fittest† (Brickley et al. , 2009, p. 8). Kodak failed to stay competitive with Fuji by failing to adapt to the changing industry of film production, also by not effectively changing their organizational architecture. Due to this, Kodak lost significant profits and the market share. Although Kodak survived, it definitely was not the â€Å"fittest† in the film industry in the 1980’s and early 1990’s. In 1993, the CEO of many years was fired, further exemplifying economic Darwinism at Kodak.

Teenagers Perception of Birth Control and Abortion

Research Report Executive Summary (Summary or Abstract) The aim of this report was to investigate woman teenager about â€Å"Teenagers perception of birth control and abortion†. So, this is the big problem in Thailand because abortions are illegal in Thailand, remain common and an important public health issue for women in Thailand. Which results from sex without protected. So that’s the big problem of women, and the purpose of this research is how teenage women think and awareness of birth control and abortion.We are finding who have been a sex, then what did you do if you pregnant while you studying. How do you do and how you solve this problem. Introduction The dictionary defines birth control as â€Å"a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant. † Birth control has become imperative in today's world, due to the global rise in population, need for fami ly planning and also to safeguard oneself from unwanted pregnancy.There are various methods of birth control that one can adopt, including the withdrawal method, or coitus interruptus; barrier methods like condom, diaphragm, cervical cap or contraceptive sponge; chemical methods like contraceptive pills, contraceptive patch, or the progesterone-only pill (POP); intrauterine methods; fertility awareness methods and more. Other than the preventive methods, one can also adopt abortion methods like surgical abortions, chemical abortions and herbal abortifacients to end unwanted pregnancies.Some permanent birth control solutions are surgical sterilization, which includes tubal ligation for women and vasectomy for men. According to records of the Department of Health, each year 10,000 students under the age of 15 have become pregnant in Thailand. An age-old issue of students premature pregnancy and their legal right to compulsory education attracts much controversy, primarily if it's rela ted to early teen pregnancy. By and large teenage girls don't intend to get pregnant. They just lack life’s experience.By denying them education, it isn't just punishing them, which is wrong anyways, but a punishment for their children and families alike. They have already been punished by having to look after a child at such young age, but to cut short their educational opportunity†¦ One can argue that the current policy of expelling pregnant teenage students is against the law, as Thailand is signatory to the convention on the rights of the child. Still, a Students Pregnancy Bill proposed by the Thai government draws a hot debate.A draft bill intends to give pregnant students the legal right to take maternal leave and continue their studies after giving birth. Literature Review These changes have been accompanied and underpinned by urbanisation, westernisation, moderation of cultural and religious norms, and the expansion of Thailand's infamous sex industry. A substant ial (and largely undeveloped) rural economy remains (details of sources available from authors on request). Sexual health is an increasingly important public health issue. nd In a recent cross-sectional survey, 43% of Thai girls aged 17 years or younger reported having sexual intercourse; one in five of these reported this experience as coercive, and one in four became pregnant. 5 Other studies in Thailand have documented increasingly early sexual debut, low rates of contraceptive use by adolescents, a growing burden of HIV and other sexual transmitted diseases in young people, rising rates of teenage pregnancy and illegal abortion, and the exchange of sex for money or gifts. and These trends are similar to those in other countries in transition and worldwide.Even if you use some other methods of birth control, condom is the king. Condoms not only prevent pregnancy, they are the only solution that protects against sexually transmitted diseases. Just in case of new romantic sexual en counters – you meet that â€Å"perfect† person, and†¦ get caught in the heat of the moment. Condoms also protect you (and potentially your partner) from urinary and vaginal infections. Although, condoms are commonly available almost everywhere, keep in mind that selection and quality may be limited.Abortions, According to the Thai law (in effect since 1956), abortions are illegal in Thailand, except for the girls under the age of 15 or with a serious illness, and when the pregnancy threatens the woman’s health or results from rape or incest. Yet de facto, the abortion law is rarely enforced, and illegal abortions remain common and an important public health issue for women in Thailand. There is evidence of wide public support led by women's groups, medical and legal professionals for the reform of abortion laws to widen the circumstances under which an abortion is legal.Abortion Policy and Practices in Thailand, Some medical professionals more or less discr etely advertise for abortion business, but many abortionists are untrained, which commonly leads to the dreadful consequences. So, abortion in Thailand is de jure legal only when it is considered necessary to protect a woman's health or in case of rape. Under the recently revised (but yet published) abortion regulations issued by the Medical Council of Thailand, the term â€Å"health† includes mental, emotional and physiological considerations as well as physical conditions.The determination that a woman qualifies for a legal abortion under that criteria can only be made by a medical doctor licensed in Thailand. This determination (and, if positive, the abortion procedure) can be done at any hospital, private or government. Though, private hospitals with religious affiliations may chose not provide that service. In early pregnancy, it can also be done at one of the many low cost clinics operated by the Thai NGO Population ; Community Development Association (PDA). For cost es timates, contact the hospital or clinic of your choice.Just remember that they will not tell you if they will be able to perform the procedure until the woman has met with a doctor. Research Methodology In this study, we will research about perception of birth control and abortion for teenagers. We are going to find the sources by giving questionnaire and interview. The survey’s target group is a woman teenager. In this survey, we will ask 50 women in Bangkok University and also 50 teenage women in Bangkok. So the total number of participant is 100 women. This number is large enough to say that the information is accurate.So we will collect the data from 100 women to get a result how teenage women in Thailand think and awareness of birth control pill and abortion. Results/Findings There were 50 women in Bangkok University an also 50 teenage women in Bangkok. So, ask them about how teenage women think and awareness of birth control and abortion. A breakdown of the responses is qualitative question, so we’ll ask them like a questionnaires form. Have you received any sex education or learned about sex before you actually have sex? Where did you learn it from? Do you think sex education is important?A lots of people told that, sex education is necessary for teenage for save health and avoid social accident, it’s very much importance to give sex education to young people. Population can be control by sex education there should be hold public awareness about sex education. Youths should be given the sex and contraceptive knowledge for their future. How much do you know about ‘Birth Control’? One of the toughest decisions that a lot of teens are whether to have sex if people decide to have sex, it means they must also take responsibility to protect themselves from unplanned pregnancy and sexually transmitted diseases.The most effective way to prevent pregnancy is abstinence. Couples who do decide to have sex can choose from many effe ctive birth control methods. Do you use any birth control methods? What are they? Please explain. Average of women use any birth control methods including condom and birth control pills make them safe sex, such as the use of male or female condoms, can also help prevent transmission of sexually transmitted diseases. Do you think birth control is important? Why? The best choice that you can make for yourself is not to have sex until you are ready.Even if you have had sex in the past, you can still choose not to have sex until you are ready. You have a right to choose for yourself if you are being pressured or forced to have sex, it is importance that you talk an adult you trust about what is going on. What will you do if you accidentally get pregnant? Each individual will have different feelings, thoughts, be in a different point in life, etc. There simply is no correct answer for everyone. It depends on personally abortions, don’t have the income to support a child, and feel it’s unfair to bring a child into the world if it won’t have a good living.What do you think about an abortion? Some think that abortion is WRONG! But some women think that abortion should be a decision that a mother should make for herself. We believe that being pro-choice is a good thing. We wouldn’t want anyone telling me what to do with my baby and we don’t think women should be forced to feel that abortion is murder. A right to choose is a very important right. Do you consider an abortion as one of the options when you get unwanted pregnancy? Why? Women face unplanned pregnancies every year. If you are deciding what to do about an unplanned pregnancy, you have a lot to think about.Where you’re thinking about having an abortion, you’re helping a women decide if abortion is right for her, or you’re just curious about abortion, you have many hear woman ask when considering abortion. What do you think is the best solution after getti ng unwanted pregnancy? Don’t have sex is the best way, condoms is second. If the guy doesn’t want to wear one then he is not a great choice to have sex with? You’re too young to get your tubes tied don’t do it yet. May best advice to you is really not to have sex get yourself together first. I know firsthand on this.Ask yourself before you have sex if I get pregnant by this guy what type of dad would he be, and will be able to deal with him for the rest of my life. Discussion According to the data that we have corrected, many women have different thoughts among the birth control and abortion. Some of them have same opinions but some are different. Therefore, most of the women that we had questionnaire thinks that sex education is important for all the teenage in Thailand today. By giving them knowledge about sexual education, they can prevent from unwanted pregnancy and transmitted disease causes by sexual relationship.Also we can decrease abortion rate i n Thailand. A lot of woman seems like they have aware that they should use birth control method when they have relationship with their partner. They said they must have responsibility and need to talk with partner about it before. Most of them are disagreed with unplanned pregnancy. Because some people are do not have enough income to raise their baby after giving a birth. They cannot take care of their baby and they might experience a hard time with a child and they will not able to make them happy. So some women think that abortion is the one of the decision that women can chose for their life.If they don’t think that they can raise their baby and make them happy, abortion can be one of a good decision. Of course, some of them are think that abortion is wrong and we shouldn’t do it, because of religious reason or thought that it is refer as killing people. At last, the best solution for prevent unwanted pregnancy problem is not to have a sex, condom is a second. It i s true that if you don’t have a sex you won’t get pregnant. Some of them said that you shouldn’t have a relationship with a partner that not willing to support unwanted pregnancy.If your partner refused to use birth control methods then you should reconsider about your partner. This problem is not about only yourself, it’s about you and your partner. Don’t forget that you can chose your partner and try to seek for a good one before have relationship. Conclusion The knowledge of sexual education should be gain in Thailand. Teenage in Thailand seems to know about birth control and they know that they should use them when they have sexual relationship, but they don’t really aware of unwanted pregnancy or abortion.So to gain the knowledge about abortion, the school needs to put more effort for sexual education in their class and give more knowledge that what will happen if you don’t use birth control protection and when woman get pregnanc y and effect for woman by abortion. To avoid the unwanted pregnancy, we should let teenage know the importance of birth control methods and persuade them to use if they think they are still too young to have a baby or not ready to have a baby yet. Recommendations * To gain and put more effort to teach the knowledge about sexual education in schools. Make an event or campaign related to birth control method and let people aware to use birth control methods. * To let people know more about abortion, such as how the abortion affect women afterward.

It provides training to employees to prepare them to function effectively in a developmental position and provide the employee with increased knowledge, skills, and abilities to perform the targeted duties. Importance of the Topic for Society or the Scientists The topic is important because it deals with the issue of the affirmative action and asks the question of what it is supposed to achieve and how it is supposed to achieve its objectives. It also provides a picture of the current public workforce. If hiring processes in public works were unbiased, and opportunities were evenly available to all citizens, workforces in general would naturally reflect the racial and sexual characteristics of the society. However, most workforces in different professions do not signify an even makeup of the society. Equality in profession and workforces is still a dream. Without providing some remedies and opportunities, these inequalities are likely to grow. Therefore, use of affirmative action has proven to ...

The Role of Intercellular Adhesion Molecules essays

The Role of Intercellular Adhesion Molecules essays This paper reports studies and findings of the intercellular adhesion molecule in relationship to the common cold virus and rheumatic diseases. The role of the cell and intercellular adhesion molecules is also examined. Cell-cell adhesion is required at all stages of development and is of importance in the establishment and maintenance of the organized structure and function of multicellular organisms. The cell is the basic unit that all living things are composed of. As an individual unit the cell is capable of digesting its own nutrients, providing its own energy, and replicating itself in order to produce future generations. Cooperative groups of similar cells form tissues, and a cooperation between tissues in turn, forms organs, the functional units of an organism (Hunter et al.,1996). Intercellular adhesion brings cells together to help perform special needs (Encyclopedia Britannica). The simplest examples of the ability of cells to recognize and adhere to one another come from organisms that live much of their lives as single cells but form a multicellular aggregate or gather, for a specific purpose (Hunter and others 1996). For example, when starved, several types of single-cell organisms band together to develop the specialized cells needed for reproduction (Hunter et al.,1996). In this process, individual cells at the center of the developing aggregate secrete chemicals that cause the others cells to bond tightly into a group (Hunter et al.,1996). In the case of slime mold amoebas, starvation causes the secretion of a compound, cyclic adenosine monophosphate, that causes the cells to stick together end to end (Hunter et al.,1996). With further gathering, the cells produce another cell-surface glycoprotein with which they stick to one another over their entire surfaces (Unter et al.,1996). The cellular aggregates then produce an extracellular matrix, which ho lds the cells together in a specific form (Hunter et al.,1996). Cel...

An optimistic outlook can banish nerves and bring excitement to any exam. Even if you prefer traditional pen-and-paper tests, oral exams can help you succeed beyond the classroom. They provide you with valuable interview-like experience to prepare you to smash your future educational and career goals. Here are a few tips and tricks to help you prepare for your next oral exam.   Know Your Subject Successfully completing an oral exam starts with knowing the material you will be discussing. The best part about these kinds of tests is that you already have all the answers. Teachers won’t ask you anything you haven’t been taught, so you will only need to discuss the material that has been presented to you in lectures, text, and video. With that being said, there are a few things that will ease some of the pressure of reciting this learned material.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Dig Deeper The best way to start preparing for an oral exam is to take a personal interest in the material. Knowing more about your topic than what is mandatory will help you predict questions that your teacher might ask. It will also give you more to talk about. Learn the background story of historical figures, authors, scientists, and explorers, even if you don’t think you need to. Many of the world’s greatest mathematical and scientific discoveries were only made because of something that happened in the discoverer’s person life. Did you know that Darwin was going to turn down his trip to the Galapagos because his father disapproved? The person we have to thank for On the Origin of Species is Darwin’s uncle (and father-in-law) who firmly believed Darwin’s discoveries would provide evidence to support Biblical claims.   Not only does digging deeper give you a better understanding of your topic, but you also have more content to talk about. If you if fully understand the ins and out of your subject, you won’t ever run out of things to say.   Predict Questions Now that you know your subject, you can begin to contemplate what your teacher might ask you. The best place to start is with the material you already have. Use previous quizzes and exams, essay prompts, and even the questions at the end of chapters to help you formulate answers. It will also be helpful for you to understand the general theme and purpose of your exam. Knowing the purpose of your exam–the topic on which you are being tested–makes crafting answers easier because you have a goal in mind. For example, if your geography teacher asks you how the climate and geographical feature affected the U.S. troops in Vietnam, you know that your answer should be built off of mountains, rivers, and weather patterns more than the success or failure of the troops because the exam is about geography. Similarly, your French teacher may ask you about a film you recently saw, but the content of the film doesn’t matter as much as your ability to conjugate verbs and use the past tense. When predicting questions, remember that one question can best asked a hundred different ways. Words like outline, describe, and detail are different ways of saying â€Å"tell me about†¦Ã¢â‚¬  Be prepared for these trigger words by asking yourself the same question a few different ways. â€Å"Chunk† Your Content When crafting your answers, try to â€Å"chunk† or group bits of information together rather than trying to remember everything as a whole. Think about the way a book is written–not as one massive piece of text, but a story divided into digestible bits with a common thread that ties them all together. Turn your exam into a story so when your teachers asks you about the economic climate of Thailand after colonization, you can follow your thread through your story without being overwhelmed, and you can easily recall and answer confidently that Thailand was never technically colonized. Use Intentional Movements It is perfectly normal to move around when you are nervous–to fidget with your clothes, to not sit still, to pace back and forth–because movement is a way to release some of that nervous energy, but it can detract from what you are saying because your exam administrator is more focused on your actions. In order to combat distraction while still releasing nervous energy, practice intentional movements. Watch Yourself The best and easiest way to practice is to first know how you move. Sit or stand in front of a mirror or use a camera or a cell phone to you can record and re-watch yourself answering questions. Don’t think too much about how you should or shouldn’t move; this is just a self-assessment. Once you understand how you tend to release nervous energy, you can take the appropriate steps to make your movements more intentional and useful for your exam. Watch Others The greatest presenters and speakers in the world aren’t those who sit or stand completely still, but rather those who use movement and nonverbal communication to emphasize what they are saying. For example, speakers will often take three or four long strides toward the audience to emphasize the importance what they are saying. They use hand gestures and facial expressions that add to the significance of understanding of a topic. Before your oral exam, take some time to watch other speakers and presenters. This can be as simple as watching TED Talks on YouTube. Note how speakers sit, stand, or walk, how they gesture, and how they answer questions. Develop Intentional Movement Practice answering questions using movements and nonverbal communication that you have observed. Lay newspaper on the floor or under your seat to make you more conscious of your movements. If you can’t seem to steady your hands, hold on to a paperclip during your exam. And remember, movement to release nervous energy is perfectly normal, and the most important focus for your oral exam is the content, not your gestures. Physical and Mental Wellness You might have spent days, weeks, or even months preparing for your exam, but if you drink too much coffee or don’t get enough sleep, all that preparation could be in vain. Remember that taking care of yourself, both physically and mentally, is reflected in your capabilities and how you perform. Take care of your mind and body, and in turn, they will take care of you.   Nutrition In the days leading up to your exam, drink enough water (aim for eight large glasses every day), get enough sleep (adults need no less than seven hours of sleep per night), and eat whole, healthy foods. On the morning of the exam, eat a light, energizing breakfast, and limit your caffeine intake. You don’t need any extra jitters!   Exercise Remember that nervous energy we talked about earlier? It is caused by cortisol, the stress hormone. Increasing your heart rate eliminates cortisol. If you can, try to get to the gym in the days leading up to your exam.   Presentation There is something to be said about the clichà ©, dress well, test well. Pick out your clothes the night before so you don’t have to fumble through your closet in the morning. Wear something comfortable and breathable that you won’t need to tug at during your exam.   Take Your Time Teachers firing questions at you can feel overwhelming, but remember that there is no need to rush into your answers. Take a moment after each question to digest what information has just been requested from you and organize your thoughts accordingly. If your teacher asks you to describe Christopher Columbus’s voyage to the Americas, take a moment to recall what your know about Columbus. You know how the voyage was funded, you know the names of the ships, you know how long the journey took because you prepared for the exam. Now that your thoughts are in order, begin to tell your teacher the story of the legendary voyage across the sea.   Ask For Help Your teachers and professors want you to succeed. They are there to help you reach your goals and prepare you for future career endeavors. Visit them before or after school, during breaks, at lunch, or during office hours. Meet with them if you are confused or stuck or you simply want to talk through an idea. Teachers are also normally the ones administering the oral exams, meaning they have created the criteria you need to meet to be successful. They are your most valuable resources and your strongest allies.

Evaluation of the 2011 Policy of the Bank of England Essay

Evaluation of the 2011 Policy of the Bank of England - Essay Example This essay discusses that in 2011, the Bank of England maintained the interest rate low even when the inflation rate was higher than the targeted level. Is this policy sound? The â€Å"monetary policy objective is to deliver price stability --- low inflation --- and, subject to that, support the Government’s economic objectives including those for growth and employment†. Low inflation itself is not defined but â€Å"price stability is defined by the Government inflation target of 2%†. Maintaining t a 2% inflation rate is the continuing target of the United Kingdom through the Bank of England which is the central bank of the UK. Yet, as indicated by Table 1, inflation was 2.1% in 2005, 2.33% in 2006, 2.32% in 2007, 3.6% in 2008, 2.17% in 2009, 3.29% in 2010, and 0.5% in 2011. If the inflation rate â€Å"target is missed by more than 1 percentage point on either side ---i.e. if the annual rate of CPI inflation is more than 3% or less than 1%---the Governor of the Bank must write an open letter to the Chancellor explaining the reasons why inflation has increased or fallen to such an extent and what the Bank proposes to do to ensure inflation comes back to the target†. During the period 2005-11, annual average bank interest rate decreased from 4.65% to 0.5% when the usually logical action to take is to increase the interest rate given the overall trend of an increasing inflation rate. If she wants to, the Bank of England can influence bank interest rates through several policy instruments such as her control over government. Over the period 2005-11 or 7 years, inflation rate was above 2% and, yet, interest rate has been made extremely low. Inflation has been on the uptrend since 2005 but interest rates were on the downtrend beginning the same year. The United States sub-prime crisis that became the trigger for the ongoing world crisis started to express itself sometime 2007. In the United Kingdom, the gross domestic product dropped in 20 09 and recovered its 2008 level in 2010 but the GDP per capita figures probably continued to decrease. UK inflation, on the other hand, has been increasing since 2005. This indicates that the ongoing UK inflation is independent from the United States crisis and its aftershocks. At the same time, this also implies that it may be possible to address the two problems separately or that specific measures are needed to address UK inflation independent from the measures needed to address the fallouts on the UK from the U.S. sub-prime crisis. Nominal GDP or GDP in current values decreased in 2009 despite an inflation of 2.17% during the year. Needless to say, the impact of this double hit of a decrease in the nominal value of the GDP combined with inflation is that the quality of life deteriorated for at least several households in the United Kingdom. Chart 1. Quarterly GDP change, 1955 to 2011 Source: Roger, et al. 2012 Using Chart 2 for looking at the period 2000-2011 within a longer ter m horizon or between 1955 to 2011, it is to see that 2000-2011 is a period wherein GDP change on a per quarter basis is lower compared to the GDP change on a per quarter basis over the period 1955 to 1980. A lower growth rate should imply a lower demand for money and provides a merit for higher levels of interest rates. Chart 3 also suggests that the pattern of

Against nuclear power - Research Paper Example However, there is equally a somewhat increasing concentration in the mastering of the nuclear fuel succession to ensure there is an adequate supply in terms of the needed nuclear fuel. The major concern involves the aspect of mastering this fuel cycle, meaning that countries trend riskily close to the nuclear weaponry capability. There have been endless protests in both the United States and Europe opposing the operations and construction of the nuclear power centres. Some of the proponents are said to have argued that the extending of the movement focus beyond the atomic plants was likely to end up alienating the government and public target individuals, thus most of the antinuclear alliances appears to have shied from certain issues including socialism and the corporate capitalism. There has been points of tension with the particular one being the amount of the emphasize that ought to be placed upon the elimination of the nuclear weapons. The antinuclear alliances began basically from an environmental initiative concerning the safety of the atomic plants, with several members in the movement calling for an increased stress involving the connections between the nuclear weapons and the nuclear power. Through the endeavoured occupations of the nuclear power plant centres, the modern movements against the atomic power is said to have adopted the civil disobedience being a primary criteria of protest, together with other various legal demonstrations and protests. It will be noted that an unscrupulous concern for the nonviolence seems to have marked attempted occupations of the atomic plants, thus winning some favourable attention on the national as well as the local media. Most of the antinuclear protesters tend to look up to the nonviolence in terms of philosophical manner that guides the whole of political and personal actions, with many others adopting it as a promising

The increasing relevance of appearance in society Essay

The increasing relevance of appearance in society - Essay Example It was mainly injured soldiers who went under the knife for reconstruction surgery (American Society of Plastic Surgeons 2011). However, since the late 1980s, the number of patients who desired cosmetic surgery began to spike; today, cosmetic surgery patients make up most plastic surgery patients. Dr. David Hargraves stated that the majority of his work now centers on aesthetic or cosmetic surgery, whereas before the 1980s he mainly performed surgeries for burns victims (Elliott 16). So, why has there been an increase in the number of patients looking for aesthetic surgery? The answer is that society has become more appearance-oriented, and many factors have contributed to this shift of thought. We can clearly see that society has moved towards a focus appearances when we consider how beauty standards have affected our lives. These days, there is a certain beauty standard that people are likely to pursue. To start with, people try to meet this standard for social reasons. Henderson-K ing and Brooks (134) state that a motivation for enhancing one’s attractiveness through cosmetic surgery is to develop one’s social status. It is a basic human desire to want to look more attractive to others, including one’s partner; this results in feeling a need to undergo cosmetic surgery (Henderson-King and Brooks 134). ... This pressure drives a person to feel dissatisfied with their body. As a result, having a negative image about their body contributes to their thinking about reshaping their bodies through surgery (Park, DiRaddo, and Calogero 110). Also, Henderson-King and Brooks (135) argue that â€Å"one mechanism through which the internalization of standards of attractiveness is likely to happen is through the influence of close others, such as mothers, fathers, and friends.† A person’s concern about being attractive is formed by their close acquaintances, as their family and friends keep transmitting messages to them through appearance-focused behavior and attitudes (Henderson-King and Brooks 135). Basically, this behavior is likely to lead to someone to feeling insecure and less confident, and this intrapersonal reason, as well as the social reason, promotes someone to change their appearance through cosmetic surgery. Among several beauty standards, the most widespread one is know n as ‘white beauty’. Across the globe, many people believe that white equals beauty. In addition, many people have a perception that white skin will result in a better economic and social status (Hunter 153). Due to these beliefs, many immigrants to the United States, such as Asians, Europeans, and African-American women, are now turning to cosmetic surgery to meet this recognized standard of beauty. This has come to be known as ‘ethnic plastic surgery’. The fact that the number of cosmetic surgeries performed from 2000 to 2008 in the United States for African-Americans increased by 145 percent and for Asians by 290 percent proves that ethnic plastic surgery has become

The History of East Timor Essay Example for Free

The History of East Timor Essay Timor is an island on the eastern side of the Indonesian archipelago and to the northwest of Australia. West Timor was a part of Indonesia and East Timor was a Portuguese controlled colony. East Timor was taken under the control of the Portuguese in the 1600s. They were in control until 1975. During 1942 the Japanese invaded East Timor whilst fighting the Australian troops. Around 60,000 East Timorese were killed for protecting the Australian troops. The Japanese were in control of East Timor until 1945. In 1975 on the 28th of November, the Fretilin declared East Timor as independent. On the 5th of December that year the Indonesian forces invaded East Timor; claiming it as a province. The U. N. did not officially recognise the move by the Indonesians. The East Timorese tried to resist the Indonesian invasion, all attempts failed. While the invasion was happening 200,000 East Timorese died. The political climate in 1975 The fear of communism had spread throughout Asia at the Vietnam War. Many countries were afraid of it and the Indonesians accused the East Timorese of trying to become communist. The Indonesian military used this as a scare tactic for the rest of the world. They claimed that they were only trying to keep East Timor under control. But really they just didn’t want them to become independent. The Australian government knew of the invasion but did nothing to help the East Timorese people. The Hawke government didn’t want to risk Indonesia making us enemies. At the time, the Indonesian government had military, political and economic support from countries such as the UK, USA and Australia. It is to be believed that these countries did not aid the East Timorese from the invasion for various reasons, such as the Timor gap, trading and cheap labour interests. The impact of the invasion in 1975 and the future repercussions The invasion of the Indonesians left peoples homes destroyed, their family’s dead and their lives uprooted. Many refugees left East Timor in search of a peaceful new home. In August 1999, the 99% of the people of East Timor voted in a U. N referendum. Four days after the referendum the tally showed that 78% of the East Timorese voted for independence. A militia leader said it bluntly, Peace? Why would we want peace? If the vote is for independence well just kill—kill everybody. Within one week the Indonesian military-backed militia started a terror campaign. Women, children, but mostly men, boys, the educated, nuns, and priests were murdered. The Indonesian government was trying to make it so that East Timor didn’t have any educated people left. The capital, Dili, was set alight as people fled. Homes, churches and even the United Nations compound were attacked. Many refugees left for other Indonesian islands. The only safe places for the East Timorese were the four cantonments in the mountains that were held by the East Timorese armed resistance. At some points in time there were said to be 200,000 to 300,000 refugees with up to 600,000 people displaced. The role of significant individuals Jose Ramos-Horta: Jose Ramos-Horta was born and raised in East Timor. In 1969 he worked as a journalist and in 1974 he was exiled to Mozambique after his attempts to make East Timor independent anger the colonial administration. When Jose Ramos-Horta returned to East Timor he joined the Fretilin in 1974. In October 1975, Jose Ramos-Horta took the group of five journalists to the town Balibo so they can film the Indonesian attack. He left the town only hours before the five men were killed. On the 28th of November that year Jose Ramos-Horta was appointed as the Fretilin’s minister of communications and external affairs. Ramos-Horta had left just days before Indonesia invaded on the 7th of December. He was in New York representing East Timor to the UN Security Council. He successfully made a pass on the resolution demanding that Indonesia withdraw. But Indonesia ignored the UN. From 1977 until 1985 Jose Ramos-Horta became the representative of the Fretilin at the UN. Jose spoke to many different councils, committees and commissions about the human rights violations by the Indonesian military. He had a peace plan that would end all the violence in his country. During his time in exile, he was trained in human rights law in Australia. In February 1996 Jose was awarded the first UMPO prize, Unrepresented National and Peoples Organisation, for his â€Å"unswerving commitment to the rights of and freedoms of threatened people† later on it that year Jose Ramos-Horta and Bishop Carlos Belo were jointly awarded the Nobel Peace Prize. In 2006 Jose Ramos-Horta take a place in the government as caretaker prime minister after many hiccups with the previous government. In 2007 he stepped down from his position while the East Timor’s first presidential election was taking place. Jose won the election with 70% of the vote. Jose Ramos-Horta was shot by rebel soldiers in 2008 and was flown to Australia. He returned to East Timor 2 months later. He continued on as president until the 20th of May 2012. If those in power, wherever we are, whichever country but also at whatever level in society that we are leaders, began working together—we would eliminate abject poverty and ensure that poverty becomes history in twenty years from now. It’s a moral duty of any of us as human beings. † The Balibo 5: In October 1975 five Australian journalists -Greg Shackleton, Tony Stewart, Brian Peters, Malcolm Rennie and Gary Cunningham- landed in East Timor. They travelled through East Timor filming the areas that they passed to show to the world. They were heading to a town called Balibo to film the Indonesian war ships of the coast of East Timor. Indonesian forces killed the five men in Balibo. We don’t know how they were killed but many believe they were burnt along with the footage they had taken on their journey so far. The journalists were reported as missing on the 16th of October. On The 12th of November Indonesian officials, whom handed their remains to the Australian Embassy in Jakarta, confirmed their deaths. These men were important because they were trying to show the world what was really happening in East Timor, not the lies that the Indonesian government were making up.

Theories for the Development of Expertise

Theories for the Development of Expertise The Nature or Nurture of Expertise Historically, expertise has been strongly correlated with inherent ability. Experts were thought to be â€Å"born† and required training only to reach their highest level of performance. This was based on ideas by Galton (1869 as cited by Macnamara et al (2014)), a geneticist, who noted that excellence in the arts and sciences tended to run within families. However, this theory alone is in contrary to what is observed in surgical training, where despite initially showing poor aptitude for practical skill, most novices will progress and become expert surgeons. Therefore, whilst innate ability is undoubtedly an important factor when carrying out a task, is it really necessary for the development of expertise? The current view, first suggested by behavioural psychologist Watson (1930), completely moves away from the need for innate ability, and suggests that experts are â€Å"made† through practice, determination and hard-work (as cited by Macnamara et al (2014)). This theory is supplemented by Ericsson et al (1993), who state that while amount of practice and experience play an important role in the development of expertise, quantity alone is insufficient, but rather quality in the form of sustained deliberate practice is more important in the development of expertise. Ericsson et al (1993) defined this as practising individual skills with the specific aim of improvement, and famously quoted that 10000 hours of deliberate practice (DP) was required to attain expertise, which they based on the estimated cumulative quantity that the best musicians engaged in over their careers. DP hence involves practising the skill at progressively more challenging levels, with feedback and reflection, in an attempt to master it. I am able to relate to this as a musician myself; I was taught never to practise by playing the same piece of music over and over again. Rather I practise my fingering with the specific intention of becoming a better pianist by challenging myself with progressively faster and more technically challenging pieces of music. Thus, whilst frequent repetition may maintain my skill level, DP is crucial for advancement. Similarly, Rees-Lee and Kneebone (2015) describe the process of DP in tailors whereby the initially learn to practice on cloth and then progress to trousers and jackets. While this sequential training is similar to surgery in that the trainee starts with suturing and then progress to operations, the benefit of a graded training program in surgery over the apprenticeship in tailoring is that of a curricula whereby increasing levels of diffi culty are specifically introduced at regular intervals over the course of the training program, thus facilitating DP and development of expertise. On the contrary, Ericsson et al and the theory of DP has been criticised for placing no weight on innate talent. DP alone does not explain why only certain people are able to successfully take up playing a musical instrument. Macnamara et al (2014) argue that the majority of people will stop doing what they are not good at, and thus talent must precede DP. Grantcharov and Reznick (2009) were critical of the 10000 hours within the surgical domain, as it is based on the assumption that surgical trainees learn at the same rate, which is not the case. Recently, Hambrick et al (2014) and a subsequent meta-analysis by Macnamara et al (2014) have shown that within the domains of music, chess, education, sport and professions there is a large variance that cannot be explained by DP. Whilst the effect of DP was strong on music, chess and sport, it was extremely weak on education and professions. This may be because DP isn’t as defined in the latter activities, or alternatively performa nce in these activities is much less predictable (for example handling emergencies in surgery, or teaching students of varying knowledge levels). Subsequently, they concluded that while DP is a very important predictor of individual differences in performance, it isn’t as significant as Ericsson et al have stated. Overall, it seems evident that in both surgical and non-medical professions, the purpose of the selection process is to pick those candidates that demonstrate the innate abilities required to be a member of their community of practice. It is however sustained DP that will allow the individual to become an expert. Sadideen et al (2013) further suggests that innate ability will both speed up the rate at which this expertise is achieved, but will also be the limiting factor to how far one can progress. Efficiency versus Innovation As discussed in the previous section, sustained deliberate practice (DP) plays a critical role in the development of expertise. Through progressive challenges, the purpose of DP is to move the expert away from automation. Thus, the term â€Å"expert† can be split into two types; the routine expert and the adaptive expert (Alderson, 2010). The routine expert is one that has developed high levels of proficiency in a task by sheer volume of repetitive experience, which has subsequently lead to automation of the task. With a limitation to the cognitive process during automation, routine experts will try to adapt a problem to their existing solution, and as such Mylopoulos and Regehr (2007c) use the term â€Å"experienced non-expert† to describe these individuals. This is supported by Gawande (2002 as cited by Alderson, 2010) who argues that anyone can therefore become a routine â€Å"expert† within a narrow range if the environment of the task remains stable. The craft of glass blowing is an example of routine expertise. Here the blower has physical mastery of the materials and tools required to successfully blow glass, and as such it has become an automated process. Atkinson (2013) describes that within glass blowing there is little or no room for alternate approaches or novelty. Tried and tested methods ar e the shared culture of the craft and within this community of practice, the same technique and materials are used worldwide. Pedagogy in glass blowing is not learner-centred, but revolves around the technique, tools and materials, and whilst there is the stability within the craft, there is also a limited routine range. In contrast, expertise in the surgical field requires a greater flexibility due to the highly individualised characteristics of each patient, and greater innovation is required to deal with the regular challenges (Atkinson, 2013). Thus the surgeon must develop adaptive expertise to broaden their knowledgebase rather than just applying it. Adaptive experts seek and utilise new problems and challenges to encourage DP so as to extend their knowledge and boost performance (Alderson, 2010). They treat learning as a continuous ongoing process, developing flexible and creative methods of solving problems, rather than speed and automaticity. In essence, adaptive experts don’t try to do tasks more efficiently, they try to do it better (Mylopoulos and Regehr, 2007c). Subsequently, the adaptive expert continually seeks to move centripetally within the model of legitimate peripheral participation; they are not happy in the periphery unlike their routine expert counterparts (Mylopoulos et al, 2009). Through their flexibility and understanding of their accumulated knowledge, adaptive experts are better able to apply their past knowledge to deal with new problems (Mylopoulos and Regehr, 2007b). Kneebone and Woods (2014) demonstrate this by simulating an operation using a retired surgical team. Here it is evident that within t he right simulated context of the operating theatre and the familiarity of the same team, the adaptive expertise of the surgeon can be utilised many years later to perform the surgery. It can be argued that other non-medical experts such as musicians are also able to do this if asked to play a piece of music many years later. From personal experience as a musician, I would counter-argue that in this situation routine expertise is used as they would just be repeating a piece of music from memory, whilst the surgeon would be utilising their knowledge and applying it to operate on a new case with all of its various anatomical and physiological permutations (adaptive expertise). Wulf et al (2010) suggests that one should push away the automaticity and non-cognitive practice associated with the routine expert, and instead aim for adaptive expertise. Although Alderson (2010) supports this statement, he points out that in surgery the processes of adaptive expertise such as DP, seeking challenges and innovation need to be monitored to prevent harm to the patient that may arise from the overenthusiastic surgeon forever seeking new knowledge and thus persistently â€Å"at the bottom of the procedural learning curve†. On the contrary, Guest et al (2001) argues routine and adaptive expertise are not separate entities, but rather two ends of a continuous spectrum. They argue that while adaptive expertise should predominate in surgery, by automating basic technical skills, this will help to free-up time for the cognitive processes needed to deal with and learn from the more important and complex situation. The true expert has therefore developed resources and p rocesses that allow effective and efficient solutions for the routine problems of practice (e.g. pattern recognition aided by illness scripts and encapsulated concepts), thus allowing a reinvestment of the cognitive area liberated through the automation process towards innovation and extending new knowledge (Mylopoulos and Regehr, 2007c).

  Ã‚  Ã‚  Ã‚   Black women's experiences and those of other women of color have never fit the private -public model.   Rather than trying to explain why Black women's work and family patterns deviate from the alleged norm, a more fruitful approach lies in challenging the very constructs of work and families themselves.

Crude oil and its value to society

Although crude oil may look like earths natural pollution, behind that thick black exterior lies one of the most important raw materials on earth. Crude oil is formed when dying plants and animals become immediately covered by sediments in seas and swamps. This prevents them from decaying and as further sediments build up the plant and animals become buried deeper and deeper. Now this takes place over millions of years and immense pressure and heat (120oc) build up and eventually these organisms turn to oil. Now this raw material is given the name as a fossil fuel because of the fact that it is the fossils remains that are turning into the oil. It can be said that when we are burning the fossil fuel we are in fact using the sun's energy which has been stored as chemical energy in the fossils for millions of years. The relative high carbon content is due to small microscopic plankton organisms.Coke and Pepsi On average, crude oils are made of the following elements or compounds: * Carbon – 84% * Hydrogen – 14% * Sulfur – 1 to 3% (hydrogen sulfide, sulfides, disulfides, elemental sulfur) * Nitrogen – less than 1% (basic compounds with amine groups) * Oxygen – less than 1% (found in organic compounds such as carbon dioxide, phenols, ketones, carboxylic acids) * Metals – less than 1% (nickel, iron, vanadium, copper, arsenic) * Salts – less than 1% (sodium chloride, magnesium chloride, calcium chloride) Crude oil is a complex mixture of hydrocarbons which are basically molecules which contain hydrogen and carbon. The hydrocarbons may vary in length and structure, from straight to branching chains and rings. Now hydrocarbons are the reason why crude oil is so important because it can do two things. 1. Hydrocarbons contain a lot of energy which can be used by man to do numerous tasks e.g. electricity generation, transport, heat etc 2. Hydrocarbons can take many different forms. The smallest formation of hydrocarbons is methane which is a gas that is lighter than air. Longer chains with 5 or more carbons are liquids whilst very long formations may be solid like wax. This is the reason why hydrocarbons are so important is because it is so versatile. By chemically cross linking hydrocarbon chains you can produce almost anything from synthetic rubber to Kerosene. In fact 70% of Britain's organic chemicals are produced due to the hydrocarbons present in crude oil. The major classes of hydrocarbons in crude oils include: * Paraffins * general formula: CnH2n+2 (n is a whole number, usually from 1 to 20) * straight- or branched-chain molecules * can be gasses or liquids at room temperature depending upon the molecule * examples: methane, ethane, propane, butane, isobutane, pentane, hexane * Aromatics * general formula: C6H5 – Y (Y is a longer, straight molecule that connects to the benzene ring) * ringed structures with one or more rings * rings contain six carbon atoms, with alternating double and single bonds between the carbons * typically liquids * examples: benzene * Napthenes or Cycloalkanes * general formula: CnH2n (n is a whole number usually from 1 to 20) * ringed structures with one or more rings * rings contain only single bonds between the carbon atoms * typically liquids at room temperature * examples: cyclohexane, methyl cyclopentane * Other hydrocarbons * Alkenes * general formula: CnH2n (n is a whole number, usually from 1 to 20) * linear or branched chain molecules containing one carbon-carbon double-bond * can be liquid or gas * examples: ethylene, butene, isobutene * Dienes and Alkynes * general formula: CnH2n-2 (n is a whole number, usually from 1 to 20) * linear or branched chain molecules containing two carbon-carbon double-bonds * can be liquid or gas * examples: acetylene, butadienes However, before we get products such as synthetic rubber the crude oil must be extracted from its reserves and then processed. Today the leading producers of crude oil include, Texas, California, Alaska, Iran, Kuwait, the middle-east etc. As you can see oil can be found all over the world and therefore different extraction methods are put into progress. Before an oil-rig/well is dug, scientific methods are put into place to determine where to find the oil. Gravimeters and magnetometers and seismographs are used to identify the subsurface rock formations which could hold crude oil. Drilling for the crude oil can be extremely difficult due to these conditions and is often a risky process e.g. some wells must be dug 7 miles deep before some oil stores are found. Today much of the oil extraction is located off shore on platforms standing on the ocean bed. In order for the oil to come up to the oil rig it has to be pumped up by using water, gas or air to force it out. Once the oil has been collected it is often transported by tanker or pipeline to the refinery. Crude oil in its raw form is a complex mixture of hydrocarbons where the hydrocarbons are of varied mass, have differing boiling temperatures and differing lengths. Now as I have mentioned previously these hydrocarbons can be very useful but before we can use them they must be made into smaller more useful hydrocarbons. This state can be achieved through a process called fractional distillation. The technique for this process uses the differing boiling temperatures of the molecules in the crude oil so that all differing molecules can be separated. The long chained hydrocarbons are broken down into narrower fractions where the boiling point amongst that fraction does not vary immensely. This process takes place in a specially designed fractional distillation column. Process 1. Crude oil is vaporized by passing through pipes in a furnace where the oil is heated to 600 degrees Celsius. 2. The oil will then boil forming vapor (gas) 3. The oil is then fed into the distillation chamber towards the bottom. 4. The distillation chamber may be 100m high and consist of vertically stacking rows of steel trays. The trays have many holes (bubble caps) in them to allow the vapor and the liquids to pass through them. The trays will help to collect the liquids that form at various heights in the column. The liquids will flow down the tray over a wier. 5. The reason why the oil is separated into narrower fractions can be explained by looking at the temperature gradient in the column. At the bottom of the tank it is extremely hot due to the freshly fed oil vapor and at the top it is cool. As the vapor passes through the tray it will come into contact with a slightly cooler liquid. This causes some of the hydrogen molecules to condense in that tray causing more violate hydrocarbons in the liquid to evaporate. This process will take place at each tray and in each tray a unique narrow range of hydrocarbons with similar properties will form. After approx 45 condensations and evaporations have taken place the crude oil has been separated into fractions. 6. The collected liquid fractions may either pass to condensers, which cool them further, and then go to storage tanks. Or go to other areas for further chemical processing. The more volatile hydrocarbons with the low boiling point form at the top of the tank and the least volatile hydrocarbons with high boiling point at the bottom. Once operating the column may be kept in an equilibrium state by maintaining the input of the crude oil at a flow rate which balances the total of the flow rate at which the fractions are removed. When a steady state exists the compositions of the liquid and vapor at any one tray do not vary. This enables the fractions at each tray to be drawn individually when required. Each tray will contain a narrow range of fractions with a narrow range of boiling points. The fractional distillation column will separate the crude oil into the following fractions: Refinery gasses, gasoline and naphtha, Kerosene, gas (diesel), oil and residue. Refinery gasses – Consist of simple alkanes containing up to four carbon atoms. They are used as fuels or as a source for building other molecules. Gasoline – Contains Alkanes with 5 – 10 carbons in the chain and is used in petrol. Naphtha – Most important source of chemicals for the chemical process industry. Kerosene – is used for jet fuel and domestic heating. Gas oil – is used as diesel fuel and as a feedstock for catalyst cracking. Residue – used as a source of lubricating oils and wax and bitumen. Bitumen – when mixed with crushed stone is the tarmac compound used for road surfaces. Although the crude oil has been separated into useful fraction, some of the separated ‘trays' can be further processed to form products that are even more useful. Cracking – To obtain more useful alkanes and alkenes Heating the oil fractions with a catalyst. Under these conditions it can brake-down high molecular mass alkanes into low molecular mass alkanes as well as alkenes. The cracking is a random process by which both C-H and C-C bonds can be broken. Therefore it is possible for by products to be produced like: Hydrogen and branched chain alkane isomers. For example Decane can be broken into: CH3CH2CH2CH2CH2CH2CH2CH2CH2CH3 (Decane) H | à ¯Ã‚ ¿Ã‚ ½CH3CH2CH=CH2 + H3C- C-CH3CH2CH3 (But-1-ene) | CH3 (2-methylpentane) Decane is broken into these two isomers because there is a larger requirement for small chain isomers than larger ones. After the cracking the hot vaporized oil fraction and the catalyst behave as a fluid. This is called the fluidized bed. Some of the hydrocarbon fraction can be broke down into carbon which can block the pores of the catalyst. We can recycle the catalyst by pumping it into the regeneration chamber where the carbon coke is burnt off in air at high temperatures. Isomerisation Is the process which we use to obtain branched alkanes. The process involves heating the straight chain alkanes with platinum catalyst to form Branched chain alkanes: CH3 | CH3CH2CH2CH2CH2CH3 à ¯Ã‚ ¿Ã‚ ½ H3C-C-CH2CH3 | CH3 (Hexane) (2,2-dimethylbutane) However these newly formed branched chain alkanes have to be separated from the straight chain alkanes and this is done by a molecular sieve. The sieve is a type of zeolite that has pores through which the straight chain alkanes can pass through but the branched chain alkanes cannot due to there bulky shape and thus they are separated off. The straight chain alkanes may then be recycled to the reactor. Reforming This involves the conversion of alkanes to cycloalkanes or cycloalkanes to arenes using a bimetallic catalyst. For example a cluster of platinum and rhenium atoms is very effective in removing hydrogen atoms from methylcyclohexane to form methylbenzene. (Methylcyclohexane) (Methylbenzene) A catalyst containing Clusters of iridium atoms and platinum enables conversions of straight chain alkanes to arenes: CH3CH2CH2CH2CH2CH3 + 4H2 (Hexane) The metal clusters have to be between 1 and 5nm thick and are deposited on an inert support such as aluminum oxide. The Rhenium and the iridium help prevent the build up of carbon deposits which reduce the activity of the catalyst. Why are Alkanes fuels? The reason for this is because of their reaction with oxygen. Alkane (fuel) + Oxygen (or other oxidizer) à ¯Ã‚ ¿Ã‚ ½ Oxidation products + Energy transfer This basically means that a fuel must react with oxygen to release large amounts of energy and Oxidation products that aren't extremely harmful to mankind. Although different chains of alkanes can produce different energy amounts and byproducts and are used for different purposes, they all comply with this equation. Below I will list the ideal characteristics which all fuels must have. * A fuel must react with an oxidizer to release large amounts of energy. * A Fuel must be oxidized fairly easily, ignite quickly and sustain burning without further intervention. * A fuel should be readily available, in large quantities and at a reasonable price. * A fuel should not burn to give products that are difficult to dispose of, or are unpleasant and harmful. * A fuel should be convenient to store and transport safely without loss. So obviously different fuels are used in different environments. In Industry For example larger fuels that produce a lot of energy that may give off lots of harmful gasses can be used. This is because in industry it will have the relevant equipment to extract the dangerous fumes and dispose of them safely. In homes however where there won't be the relevant equipment to handle toxic fuels, more environmental friendly fuels can be used like gas. And for transport we have to consider the transporting of fuel issue so petrol which is a liquid can be used rather than more environmental friendly hydrogen as there is a possibility of leakage as it is a gas. However the world is subject to change so in 10 years time other fuels maybe used in place of these. Problems with these fuels There are various problems with these fuels. One of the major ones is that we as a nation rely on them too much (Coal, oil and gas). As they are fossil fuels they are in effect none renewable resources. At our rate of consumption it is predicted that these resource will be depleted within 100 years. Also the fossil fuels are the raw materials which supply the feed stock for our chemical industry. They can be processed to produce useful products such as; Polymers, medicines, solvents, adhesives etc. So how long can we afford to burn our chemical feedstock? There is also the issue of carbon dioxide emissions of these fuels. This is the major contributor to the greenhouse effect which causes the temperature of our environment to increase dramatically. Due to this, precautions are being made to reduce these emissions. Britain has been set a target to reduce its emissions by 35%. This could be achieved by the outright ban of coal and oil but nations are reluctant to do this as they have become so reliant on these resources. There is also the possibility of a spillage which can pollute rivers and streams and the environment. This can cause death to animals and plant life and there is also the enormous cost of cleaning it up after the disaster. If the carbon based fuel does not completely combust in the furnaces, carbon monoxide is produced and this can cause death by interfering with the blood stream. 2C + O2 à ¯Ã‚ ¿Ã‚ ½ 2CO (impartial oxidation to give carbon monoxide) Also sulphur and nitrogen dioxide can be produced which contribute to harmful acid rain. Development of renewable resources As our reserves of fossil fuels are limited we must find alternative sources of energy. In the search for the alternatives, chemists and other scientists are now working to develop renewable resources such as: Biofuels This is when plants are grown to be used directly as fuels e.g. wood, animal waste and plant waste to produce alcohol and using waste products to produce biogas. Advantages – Renewable, help to reduce waste, used with simple technology. Disadvantages – Not large enough supply to replace fossil fuels at present rate of use. Nuclear Fuels Chain reaction involving the nuclei of isotopes of uranium 235 splitting to produce vast amounts of energy. Advantages – No carbon, nitrogen or sulphur as polluting byproducts. Disadvantages – Radioactive waste products are difficult to store and treat; which is a very expensive process Moving air: wind Energy of moving air is transferred into the motion of windmills and wind turbines Advantages – Renewable pollution and waste free; can be used in locality where energy is needed Disadvantages – Expensive, not reliable, noisy and ugly to the environment Hydroelectricity Water stored behind dams and waterfalls can be released and generate electricity by turning a generator. Advantages – Renewable, predictable, waste free and can be used on large scale. Disadvantages – Expensive to install, environmental impact of dams etc. Solar panels Panels of solar heat collectors, used to heat water in parts of world were sun is plentiful. Advantages – Renewable, no pollution Disadvantages – Require a lot of sunshine, Expensive initial cost, Very large scale to be suitable. Hydrogen Hydrogen is extracted quite cheaply from water by electrolysis and is used as a fuel. Advantages – No pollution as water is the only waste product. Disadvantages – Too dangerous and explosive, difficult to store and to use for transport or in domestic situations.
