Introduction Decision analysis provides powerful techniques to structure complex problems, identify optimal choices, and facilitate communication between the decision analyzer and the person makes the decision. One of the most important values of these techniques is that they enable decision making to be rational rather than intuitive or holistic. They provide a framework for rational decision making in an uncertain environment. As modern decision analysis has been studied for more than five decades, there has been significant improvements in the practices used. These methods have been implemented by companies and organizations and proved to be successful as well as constructive. However, there are also plenty of examples when the recommendation were not implemented or even if they were, they failed to truly support the decision maker(s). Kusnic and Owen found that the implementation rate decreases with the importance of the problem (1992). These cases, however, enabled scientists detect the major deficiencies of this approach, and helped them to work out new developments to help overcome these limitations. The aim of this paper is to give insight into the process of decision analysis with the help of real life examples and case studies, and show the extent to which the approach has proven to be beneficial. The paper also going to summarize the limitations of decision analysis as well as the techniques that have been developed over the time.

There are plenty of scary and damaging myths about HIV, most of which exist because people are scared of it. You cannot get it from kissing, sharing exercise equipment, animal scratches, sneezing, and you will not even catch it if somebody ejaculates onto your skin unless they do it onto an open and bleeding wound. 1 - You Can Catch It From Lipstick Women sharing lipstick will not pass HIV along, nor will kissing women that have shared lipstick. You can catch other things such as Herpes from kissing, and even from sharing lipstick. 2 - HIV Started With A Man Humping A Monkey This is a very untrue myth. HIV is a disease that affects certain primates. In some it lies dormant and does nothing, but in humans it causes the degradation and destruction of the human immune system. It was and is passed through humans eating primate (monkey) flesh without cooking it properly. 3 - You Can Get HIV From Being Poked With A Needle This myth came from both a misunderstanding and an urban legend. The urban legend is that people would tie syringes under handrails in tower blocks. People would walk down the stairs with their hands on the rail and be poked by the needle underneath. To the side of the rail is the words, Welcome to the world of AIDs. That is the urban legend, but the truth is that it is very difficult to become infected with HIV that way.

Members of this group have spent time in jail for sometimes simple actions which violated this law. This minority group has been the target of racial violence as well. These attacks of resulted in everything from minor injury to death. In this chapter we will discuss the historical hardships faced by this minority group. The experiences of African Americans throughout the history of the United States of America have be intense, tragic and challenging to this racial group. The earliest experiences of African Americans in this country would be as they were bought and brought in as slave labor. These were African natives captured during battle and sold to slave traders from around the world. They were forced in to unsafe shipping holds where many died on the trip over. They were then sold and treated like cattle. African Americans we renamed by their new owners, told what they would do, when they would do it and how they would complete the task. We will write a custom essay sample on Historical Adversity Faced by African Americans or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Families were separated, marriages were dissolved and children were taken from their parents. They were forced to breed to make better workers and forced to remain uneducated. When slaves were freed, African Americans found a new set of problems. The only skills they had were what they were forced to do while owned. This meant they were limited to the same work and were paid almost nothing in comparison to members of the majority group performing the same task. Nearly a century later, as the skill sets of this minority group had drastically widened, African Americans found themselves forced in to separate facilities by law. As the battle to eliminate these boundaries began, violence often occurred. Members of this racial group often found themselves the victims of hate group aggression and violence, often resulting in death. These experiences were harrowing and held not only physical and psychological ramifications but lead to a great deal of political, social and cultural tension as well. Facing such intense issues throughout their time in this country, African Americans faced great number of social, political and cultural issues. Even as far back as the time of slavery, politics came in to play. Many slave owners treated slaves as property but wished to use them as a way to carry more political sway. They used the number of slaves they owned to count as partial votes. This meant that plantation owners would vote once but count as many votes. The act of freeing slaves was a political gesture which achieved nothing but was done to make a political statement. After slavery was abolished, social and cultural issues began to come in to play. Newly freed, slaves needed to establish their own culture and quickly found themselves forced in to separation from the rest of society. As time went on and culture was developed, society began to reduce the drastic manner of separation between African Americans and the majority but still left the group segregated. African Americans began fighting for the removal of segregation through political means. This fight caused a violent reaction in communities. In order to fight this, social and cultural boundaries were redrafted. However, African Americans were fighting not only societal discrimination but also laws in place to enforce much of this discrimination. Unfortunately, for a large portion of our countries history, laws were in place to enforce segregation and unequal treatment. The most notable of these laws were those governing segregation. This was legislation passed to keep members of the African American community forcibly separated from the majority group. These laws forced members of this racial group to relinquish seats on public transportation, use separate restrooms and attend separate schools. While the argument was made that these facilities were separate but equal. In the 1960Ã¢â¬â¢s the National Association for the Advancement of Colored People, or NAACP, began fighting many of these civil rights issues. The group fought to use the Brown v Board of Education ruling across the country to work towards desegregating schools nationwide. The group also began pushing for equality in employment, working towards equal pay and equal opportunity for member of the African American community. Since the NAACP began pushing for equality many laws have been enacted to help promote equality. In 1963 John F Kennedy pushed a piece of equal rights legislation in to congress before he was assassinated. In 1964 Lyndon B Johnson worked hard to persuade congress to pass legislation seeking to eliminate employer discrimination. Since then this legislation has taken the concept even further. Affirmative action is a prime example of this evolved civil rights legislation. The idea was to encourage employers to not overlook minorities for positions or promotions based on race. The idea was to punish employers avoiding more qualified candidates based on race. The changes in legislation from hindering to helping have done a great deal to bring about equality for African Americans.

An example of a polymer is PH (polyhydroxybutyrate) -PH is a natural polyester polymer produced by the bacteria/enzyme Allegiances Torturous as an energy storage material. Production To produce the polymer PH, genetically modified bacteria such as Allegiances Torturous is placed in an aqueous medium and supplied with a rich carbon based food source such as glucose, providing growth(bacteria getting bigger) and proliferation(bacteria dividing and multiply). Once the population is large enough it is moved to a different environment where certain nutrients such as nitrogen is restricted from the nutrient supply so the organism stops reproduction and the bacteria produces PH as a nutrient source to be metabolites later. -When the process is done the bacteria is lased (cut open) and cleaned, PH is extracted with a solvent which can be a number of different substances, this too is separated from the remaining mass.By placing the solvent into water, PH will precipitate into a fine white po wder with a purity of at least 98%, the solvent is also usually recycled in a closed system. We will write a custom essay sample on Monomer or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page -The powder collected in the extraction stage can be made into pellets or small chunks using machinery, to improve durability and trench, plasticizer can be added, these pellets can be used in moulds or made into larger pieces by compaction.Properties -High tensile strength of mamma(with additives) -Thermoplastic (softens when heated, flexible, easily reshaped and is recyclable) -Insoluble in water -High PM -Biodegradability -Absorbability/Non-TOXicity -Brittle however it can be genetically manipulated with additives in order to make it more durable. Uses -Can be used in the fast food industry for things such as utensils, cups and plates because PH is insoluble in water, non-toxic, high tensile strength and degradable -The biodegradability of PH has great appeal for the potential replacement of widely used polymers derived from petrochemicals.Petrochemicals such as polypropylene and polyethylene are often used for packaging, although they are hazardous to the environment, as when th ey are discarded they do not decompose. -PH could thus be a replacement for disposable nappies and packaging in the form of bottles, plastic bags and cling film as PR is flexible, biodegradable and non-toxic. -This would eliminate the need for recycling without fear of pollution, for PH can be impolitely decomposed by bacteria into only carbon dioxide and water. The absorbability and biodegradability of PH also open it to many other uses, which are currently not possible with other petrochemical products. -PH is currently being utilized in the medical industry, where plates can be made from PH to be left in place to heal fractured bones due to its strength and once the bones heal PH is slowly broken down within the body without any adverse effects. Sutures Can also be made from PH as it is non-toxic and objectionable meaning that it wont be rejected from the human body as it is insoluble in water meaning that it wont dissolve in the body Advantages -It is biodegradable so unlike polyethylene and other petroleum derived plastics it will help to reduce the levels of rubbish in landfills. -It is compatible with organisms (objectionable) so therefore it is not rejected by our bodys immune system so it can be used safely -It is a renewable resource Disadvantages -The main disadvantage of PH is that it is extremely expensive to produce, costing approximately 4 times that of polyethylene. The demand for PH currently is not high enough for its production to be economically viable -The reduct ion of PH requires medical professionals which in summary WOUld increase the cost of production -Extremely brittle so therefore it cannot sustain high impacts while being used however currently this has been solved by adding plasticizer and other additives yet this increases the cost of production. -The recovery of the polymer can be difficult while giving only modest yields.Evaluation and Current progress -Currently PH is considered not an efficient alternative to petroleum based polymers such as ethylene due to its cost as it is approximately 4 times for expensive than ethylene. However as technology advances it may one day become an efficient alternative as modifications such as additives are used to make the polymer more cost-effective as well as different production are being sought out. -For example, experiments are being done to find an alternative for nutrient sources.They are starting to be derived from waste material such as molasses and other agricultural wastes. This will in turn reduce the cost of production greatly -Also recent genetic engineering results have proven that transferring the enzyme, Allegiances Torturous into E. Coli acetate will create an environment that will allow faster growth, higher yields and easier recovery meaning that one day PH can become a viable alternative to petroleum based polymers.Discuss the need for alternative sources of the compounds presently obtained from the petrochemical industry -Many polymers and fuels are currently derived from petrochemicals such as crude oil which are convenient and economical Petrochemicals are chemicals made from compounds of natural gas, coal and petroleum -Over the last century the use of petrochemicals has increased dramatically since it serves as a primary source f energy for transportation , while it is also used to produce materials such as plastic. However the world reserves of petrochemicals are dwindling due to: There nature of being a non-renewable and unsustainable resource Increasing rates of consumption and demand Rising costs due to its depletion Substantial environmental issues such as pollution from the combustion of these petrochemicals and the release Of greenhouse gases. -Currently, it is predicted that the Australias crude oil and petroleum reserves will last around another 10-20 years and since fossil fuels are not renewable they will non run out -Therefore we need an alternative source of petrochemicals that are renewable and sustainable and that source is biomass. Biomass: carbon based material produced by living organisms, mainly plants -Alternative sources such as biomass would be favorable to use as it would prevent problems such as: Facing the same problem of exhaustion that petroleum will be facing soon Causing the release of more carbon into the carbon pool in the form of carbon dioxide Explain what is meant by a condensation polymer -A polymer formed when monomers combine via a chemical process called indentation which involves the elimination of a small molecule (often water or methane) as by-product when pairs of monomer molecules join together.Examples of condensation polymers include natural ones such as cellulose, starch, cotton and also synthetic (man made) ones such as polyester, nylon and PET Describe the reaction involved when a condensation polymer is formed -In a condensation reaction two monomers chemically combine by eliminating a small molecule as by-product (usually water or methane) Two molecules join together and rele ase another. The type of end product resulting from a indentation popularization is dependent on the number of functional end groups of the monomer which can react -Usually formed by the reaction of 2 functional groups egg.C-NAH (amine), C-OH (alcohol), O=C-OH (carboxylic acid), O=C-NAH (Amide) n(HO-C6H1004-B) + (n 1)H2O -In the formation of cellulose seen above, n p glucose monomers combine to form the cellulose chain and (n 1) molecules of water where n is the number of monomers When two ; glucose monomers react, a hydroxyl group from each combine to condense a water molecule, leaving an oxygen atom linking the two monomers. This process repeats to form a long chainDescribe the structure of cellulose and identify it as an example of a condensation polymer found as a major component of biomass -Cellulose consists of a hexagonal carbon based rings with five carbons and a lone oxygen atom in each ;-glucose monomer. The bottom 4 carbons each have a hydrogen and hydroxyl group link ed where it has free electrons and the lone carbon on top has a hydrogen and COACH group -Cellulose as said in the previous dot point is a natural condensation polymer that undergoes a condensation reaction with the removal of water For bonding to occur, every second glucose molecule must be inverted.This results in the COACH group to be inverted, resulting in a linear structure Of the polymer. Strong H bonding between OH groups makes cellulose strong hard and resistant to chemical attack and insoluble in water since the hydroxyl groups cannot interact with water and they therefore cannot break the hydrogen bonds. This is an example of why cellulose can be used in building material such as wood and insulation -Also the bulky COACH substitutes makes accounts for cellulose rigidness and high crystalline. The existence of both intra-chain (within chains) and inter-chain (between chains) hydrogen bonding makes cellulose a very strong and hard to separate monomer. -Since cellulose has hundreds and thousands of ;-glucose monomers in a chain it is hard, rigid and has a high melting point. -In summary there are many factors that make cellulose a very strong and rigid polymer. Cellulose is the most abundant polymer in nature since it is used in cell walls to provide strength -Normal dry plant matter (which forms a large proportion of the earths biomass) are made of about 50% cellul ose, and plants on earth produce approximately 500 billion tones of the substance each year. Therefore it is the most abundant component of the biomass. It is a renewable source that is formed during photosynthesis Identify that cellulose contains the basic carbon-chain structures needed to build petrochemicals and discuss its potential as a raw material -The basic carbon-chain structures that are used to make petrochemicals are short- chained alikeness such as ethylene, propane and butane and since glucose contains six carbons it has the potential to be used to convert into the alikeness aforementioned Cellulose to Ethylene -Cellulose is a major component of biomass where cellulose itself can be Rosen down and since it is from biomass It is renewable. This means that cellulose contains the basic carbon chain structures that can be used to build compounds that are presently obtained from petrochemicals -However before it can be used in petrochemicals it must be converted in to ethylene through these steps: 1 . Break the cellulose down into glucose using either Decomposition with Noah and cellulose or Acid Hydrolysis (with heating) Th e reason for using these methods is that there are many hydrogen bonds between chains making cellulose quite compact and hard to separate. 2. Fermentation of glucose into ethanol Yeast and bacteria ferment the glucose down into ethanol, releasing CA Egg.

Ghostwriting A Lesser Known Career Path that Pays Big Graduating with an engineering degree, I had no clue I would end up being a freelance writer. I chose to be one, as it best suited my life during the recession period back in 2009. Like many other writers who get stuck with low paying content mills like Elance (now Upwork), I started my career earning peanuts. That changed when I did research for a blog post in 2013 about how much ghostwriters earn. That research taught me that I was highly undercharging at $1 per page. The first eBook I ever ghostwrote for a client was over 50 pages long and paid only $50. And that included ElanceÃ¢â¬â¢s and PayPalÃ¢â¬â¢s fees, too! Today, in 2018, I charge as much as $1-$2 per word. I charge more for creative work or fiction than for nonfiction. If the work requires extensive research, the rate runs higher. This means ghostwriting a 10k words novella would easily earn me $10,000. Now, imagine what a full-length novel of 60,000 to 100,000 pays. Ghostwriting is a lucrative niche that many writers donÃ¢â¬â¢t know much about. Why Ghostwrite? The truth is: I have tried self-publishing. This requires time to market and sell your books. Ghostwriting is a lot easier, less stressful, involves less marketing, and pays well. When I started my career as a freelance writer, I was trying to raise a family while still being a Ã¢â¬ËgoodÃ¢â¬â¢ housewife. I needed, at this point in my life, to work from home. Ghostwriting seemed to fit my lifestyle perfectly. How I Land Ghostwriting Gigs Ghostwriting just fell into my lap, but logically it is a small leap from freelance writing. I was writing blogs and articles when one of my repeat clients asked if IÃ¢â¬â¢d be interested in ghostwriting ebooks. I ultimately wrote a large number of them for the same client. He was kind enough to spread the word to his peers which landed more work. As the owner of a writing business now, I acquire most of my work through my Facebook page. ItÃ¢â¬â¢s not that my clients are too lazy or inept to write their own work. They are just too busy with careers or family to create the work they wish to market, which is the norm in todayÃ¢â¬â¢s world. Networking helps me too. When I meet someone new and introduce myself as a ghostwriter, people are keen to share brilliant ideas or stories for their books and have me jot them down for them. So many people have a story, but not the skill nor time to bring them to fruition. Is Ghostwriting for You? If you are attached to your writing, probably ghostwriting isnÃ¢â¬â¢t a good fit for you. However, if you enjoy playing with othersÃ¢â¬â¢ ideas and molding them into your own words, it might just be your niche. Does Ghostwriting Pay Better than Traditional writing?Ã It sure does, but you donÃ¢â¬â¢t get rich overnight. There are some freelance ghostwriters claiming six figures a year. They do earn that amount, but they didnÃ¢â¬â¢t right away. Build upon your portfolio and reputation first. Initially, ghostwriting will pay your bills; your ghostwriting money. I enjoyed my first holiday to the south of France and then in the States in 2015 and 2016 respectively. In 2017, my family went to Spain and Pakistan. For 2018, IÃ¢â¬â¢ve planned a special surprise as we will be celebrating our 10th wedding anniversary in December. All thanks to ghostwriting, I am enjoying a life that many just dream of. Brief
