Examining The Bromination And Debromination Of Cholesterol Biology Essay

Examining The Bromination And Debromination Of Cholesterol Biology Essay Bromination/debromination which is an important organic reaction that aims in purification of crude cholesterol from impurities which include 3-cholestanol, 7-cholesten-3-ol, and 5,7-chlestadien-3-ol was performed in a laboratory scale for two weeks. Due to steric constraints, only cholesterol reacted with bromine and crystallized from the solution making it possible to be separated (Feiser, and Williamson 63). The dibromocholesterol formed is regenerated by reacting with Zinc dust. In addition, three methods were used to evaluate the effectiveness. These were Sodium Iodide test, Silver Nitrate test, and Sulfuric acid test. NaI test showed a positive response as color changed to yellow. The formation of the precipitate also indicated a positive result. The sodium iodide reagent reacted with 1 ° and 2 ° alkyl halides through an SN2 mechanism.  On the other hand, the silver nitrate reagent reacted with 2o and 3 ° alkyl halides through an SN1 mechanism.   Negative results were observed for both the commercial cholesterol and 1-chlorobutane (Zubrick 38). Conversely, the t-butyl chloride gave a positive result for the AgNO3  test and a negative result for the NaI test. The synthesized cholesterol was 0.29 gram and the theoretical yield was 1.08 gram. This gave a percent yield of 26.9 gram. Although this was a low yield the TLC analysis confirmed a high purity of the synthesized cholesterol. The melting point of the synthesized cholesterol and commercial cholesterol seems to fall in the same range. This confirms the purity of the synthesized cholesterol. TLC analysis was carried out to confirm the purity of the analysis. The distance traveled by commercial cholesterol was 5.5 whereas that travelled by the synthesized cholesterol was 4.6. The absence of other spots on the TLC plate confirms that there were no contaminations present in the sample. Introduction Cholesterol is an important steroidal compound found in both animals and plants. Despite the fact that cholesterol causes diseases, it plays a vital role in life. For example, cholesterol is the main structural component in cell walls and in myelin sheath formation. It is also a major precursor for most steroid hormones. Crude cholesterol is isolated from natural sources and various methods have been used in its purification. Crude cholesterol contains approximately 3-5% contamination. Some of the contaminants are 3-cholestanol, 7-cholesten-3-ol, and 5,7-chlestadien-3-ol shown below. Figure 2: Some common contaminants of commercial cholesterol The main objective of this experiment was to purify commercial cholesterol using organic reaction chemistry, including the use of the electrophilic addition. For complete purification of cholesterol from the above impurities is achieved by a reaction of bromine with cholesterol to generate dibromocholesterol. Because of the steroid ring structure present in these compounds that causes steric constraints, only cholesterol reacts with bromine to form an insoluble diaxial dibromo compound through electrophilic addition. On the other hand, cholestanal does not react with bromine and the other two contaminants are dehydrogenated by bromine leading to formation of soluble dienes and trienes respectively. The dibromo-cholesterol precipitates as a solid leaving the other impurities in the reaction solvent. A purification step such as solvent washing or crystallization is carried out to separate the solid from the impurities. The so lid dibromo-cholesterol is then reacted with zinc in order to regenerate pure cholesterol. Figure 1: Reaction Scheme for the Bromination/Debromination of Cholesterol To test the effectiveness of this reaction three different chemical tests namely sodium iodide in acetone, silver nitrate in ethanol test, and sulfuric acid test, were performed. Each of these tests is selective for a specific functional group. Dibromocholesterol contains both primary and secondary alkyl halides and reacts with a sodium iodide in acetone and silver nitrate in ethanol to form a precipitate or a cloudy solution. In addition, the presence of double bonds in dibromocholesterol in form of alkene makes it possible for the formation of a fluorescent green sulfuric acid layer and a red chloroform layer when reacted with sulfuric acid (Landgrebe 78). Material and Methods 1g of commercial cholesterol was added to a 25 mL Erlenmeyer flask. 7 mL t-butylmethyl ether was measured with a graduated cylinder and added to the flask containing the cholesterol and a magnetic stir bar. A water bath was then set up on the hotplate in the hood. The Erlenmeyer flask contain the reaction solution was inserted into the water bath and clamped as shown below. The heat and the stirrer were turned on and gently heat until all the cholesterol dissolved in t-butylmethyl ether. Figure 3:   Set-up for bromination reaction (Note: the actual reaction mixture is not blue) The flask was removed from the water bath after all the cholesterol was completely dissolved and allowed to cool to room temperature. After the cholesterol solution was cooled, the flask was clamped to the ring on the hot plate as shown in figure 4 and stirred without heating. A burette was then used to dispense 5 mL of bromine solution into the flask. A precipitate solution formed almost immediately. Figure 4:   Set-up for the Addition of Bromine The water bath was replaced with ice and tap water and the reaction solution stirred intermittently with a glass stir rod for ~ 10 minutes to complete the crystallization of the product. About 20 mL of the t-butylmethyl ether acetic acid solution was then dispensed in a clean 50 mL Erlenmeyer flask which was clamped to a ring stand and allowed to cool in the ice bath. A vacuum filtration was done using a Buchner funnel and filter paper. The solid in the filter was washed using ~10 mL of the cooled solution of t-butylmethyl ether acetic acid and then with ~10 ml of methanol. The solid was then allowed to dry with the vacuum on for about 5 minutes. the dibromocholesterol melting point was measured and recorded. The dry solid was weighted and sealed in a vial and stored for next experiment. To debrominate cholesterol, 20 mL of t-butylmethyl ether, 5 mL of acetic acid and 0.2 g of Zn dust were added into the Erlenmeyer flask containing the dibromocholesterol solid. The mixture was swir led for 5-10 minutes in the hood and sonicated in 5 minutes to allow the reaction to go completion. After sonication the solids present were removed by gravity filtration method into a clean 125 mL Erlenmeyer flask. The filtrate was transferred to a 125 mL separatoryHYPERLINK http://community.acphs.edu/bbcswebdav/institution/Arts%20and%20Sci/Courses/CHE211/Common/lab/Organic-sde/BP-Dist/BP_General.html funnel in which 20 mL of deionized water was added, shaken and allowed to separate into layers. The two layers formed were then separated as water layers and organic (ether) layers. The ether layer was washed with 20 mL of 10% NaOH and then 20 mL of saturated NaCl solution. 100mg of the drying agent magnesium sulfate was added to the organic layer and the solution swirled until dry. The drying agent was removed by gravity filtration using a glass funnel fluted filter paper and a very dry 50 mL Erlenmeyer flask. The flask was placed in a warm water bath and then ice cooled for 10 minut es until all but 5 mL of the ether remained following a precipitate formation from the solution. The remaining solvent was decanted and the synthesized cholesterol transferred and allowed to dry in the hood for 20 minutes.The dry solid was weighed and the weight recorded. In addition the melting point was also taken and recorded. To evaluate the effectiveness of the bromination reaction three chemical reactions mentioned above were carried out. NaI in acetone test Five test tubes labeled A, B, C, D and E were used for this test.   About 30 mg of the commercial cholesterol starting material was added to tube A; ~30 mg of dibromocholesterol to tube B; ~30 mg of the synthesized cholesterol product to tube C; ~0.3 mL of 1-chlorobutane to tube D; and ~ 0.3 mL of t-butyl chloride to tube E.   In addition, about 3 mL of acetone was added to each tube to completely dissolve all the compounds.   Solutions A-E was used to do the NaI in acetone test as well as the AgNO3 in ethanol test. Tubes A-C did the TLC as well. The NaI in Acetone and AgNO3 in Ethanol tests were performed by setting up a test tube rack containing ten small test tubes. The test tubes were labeled N1 N5 and A1 A5. 1 mL of NaI in acetone reagent was added to test tubes N1 N5, and 1 mL of AgNO3 in ethanol reagent to test tubes A1 A5. This was followed by adding 5-8 drops of A solution to test tube N1 and tube A1, 5-8 drops of solution B to test tube N2 and tube A2, 5-8 drops of solution C to to test tube N3 and tube A3, 5-8 drops of solution C to test tube N4 and tube A4, and 5-8 drops of solution C to test tube N5 and tube A5. The test tubes were heated for a while and all the observations recorded. The sulfuric acid for alkenes test was performed by additional solutions of cholesterol and dibromocholesterol with five dry-cleaned test tubes 1-5. 10 mg of commercial cholesterol was placed in tube 1, ~10mg of the dibromocholesterol to tube 2 ~10 mg of your synthesized cholesterol to tube 3, ~10 mg of 2-chlorobutane to tube 4, and 10 mg of cyclohexene to tube 5.  About 1 mL of chloroform (CHCl3) was added to each tube and vortex to completely dissolve all solids.   In addition, 0.5 mL of H2SO4 was then added to each tube. The observation for this reaction was recorded in the notebook. The TLC analysis of cholesterol and dibromocholesterol was performed by obtaining a silica gel TLC plate and setting it up to run TLC analysis on solutions A-C above. The plate was spotted with each solution and developed by placing the plate using 30% ethyl acetate: 70% hexane as the mobile phase. The developed plates were viewed under UV lamp and in the I2 chamber and observations recorded.

The theoretical yield was 1.08 grams. The actual yield was calculated by taking the difference of the weight of the round bottom flask and the synthesized cholesterol by the synthesized cholesterols weight alone. The percent yield was calculated to be 26.9 percent. The synthesize process was not efficient due to the low yield and percent yield of the synthesized cholesterol. The melting point of the synthesized cholesterol and commercial cholesterol seems to fall in the same range. This confirms the purity of the synthesized cholesterol. NaI test showed a positive response as color changed to yellow. The formation of the precipitate also indicated a positive result. The sodium iodide reagent reacted with 1 ° and 2 ° alkyl halides through an SN2 mechanism.  On the other hand, the silver nitrate reagent reacted with 2o and 3 ° alkyl halides through an SN1 mechanism.   Negative results were observed for both the commercial cholesterol and 1-chlorobutane. Conversely, the t-butyl chloride gave a positive result for the AgNO3  test and a negative result for the NaI test. The stationary phase of the TLC test was the silica gel TLC plate and the mobile phase was 30% Ethyl Acetate/70% Hexane (Table 6). The distance traveled by commercial cholesterol was 5.5, and for the synthesized cholesterol was 4.6. The difference in the distance traveled and the R f values of the samples commercial and synthesized cholesterol were pure. Since there were no other spots visible on the TLC plate was a clear indication that there were no contaminations of other chemical compounds present in the sample.

The Oedipus Complex in Oedipus the King :: Sophocles

In Oedipus the King, once upon a time in a kingdom far, far away Queen Jocasta was expecting a baby boy, but one day Tiresias (a blind prophet) dropped by one day to see the queen to give her bad news about her baby. Tiresias said "My queen, the son you will bear will kill his father and marry his mother!!!" The queen was appalled by this news, thus, after the queen had her son she immediately drove him away, by leaving him in the dark, verdant woods. A herder from another kingdom found the baby boy and immediately notified his king about the baby. The king adopted the newborn boy and named it Oedipus. When Oedipus was grown up (in his twenties) he heard a legend that a prince from a kingdom far, far away will kill his father and marry his own mother. Oedipus was frightened that he will kill his father and own marry his own mother so he embarked on a journey to escape the myth. When Oedipus was traveling in his chariot he met a man in the middle of the desert, and the young arrogant Oedipus killed the man. (He did not know that he just killed his biological father) In the gates of Thebes, a sphinx was guarding the kingdom slithering back and forth. Oedipus finally talks to the sphinx, ?Maybe you can spare us some food, my kingdom was shambling into death.? ?Well, well, do you want to enter the kingdom to speak to the queen?. ? ?Yes,? replied Oedipus ?I have a riddle for you my child. If you answer it correctly, you may talk to the queen and you have heard about our king who has been missing for days. We assumed he is rotting in the middle of the desert. I guess the vultures will have a feast? In addition to talking to the queen about your discrepancies you can also marry the widowed queen.? The sphinx asked Oedipus, ?What walks on four legs in the morning, two at noon, and three in the evening?? ?A man,? Oedipus replied and he was correct. So basically he can marry the queen of Thebes and that makes him the king of Thebes. (But keep in mind Oedipus is going to marry his own mother.) The King had the Queen of Thebes four children, two sons, Eyocles and Polynices and two daughters, Ismene and Antigone.

Not the Sound of Silence Footnoting the Pop/Rock Sounds of the Library :: Essays Papers

Not the Sound of Silence Footnoting the Pop/Rock Sounds of the Library While in the University of Arizona's Music Library evaluating their reference collection for a class project, I came across the following book and annotated it for my pathfinder: Green, J. (2002). The Thematic Guide to Popular Music, Nashville: Professional Desk References. This massive guide categorizes music by lyrical theme(s) and/or song titles. For instance, there are listings of songs by days of the week, women's first names and cities around the world. The perennial themes of love, romance and relationships are broken down into 25 sub-categories. Paging through it spurred me to wonder about songs written about or songs referring to libraries or librarians. While there were song listings galore referring to books (e.g., "Book of Love" by the Monotones and "Little Red Book" by Burt Bacharach/ Hal David), librarians and libraries were not even a category, subcategory or even crossed-referenced! This void gave me the impetus to do my own brief exploration and survey, drawing upon the vast resources of the web, friends, and my record collection, of the brief instances where the music world danced in library land. Tori Amos-"Tales of a Librarian" Classmate and Health Science librarian Virginia Sanchez filled me in on this one. I looked it up on Allmusic.com and found it was a collection of her hit songs. The record reviewer MacKenzie Wilson even writes, "Tales of a Librarian: A Tori Amos Collection is not only one of the most intriguing titles for a hits compilation, but the package itself captures only the best from Amos' years spent with Atlantic." BiblioTech editor Lori Ito Hardenbergh recently mentioned that songs on this album are even organized according to the Dewey Decimal Classification (DDC) system! Check out the following link from Library Journal, which succinctly provides "an abstract" to her recorded tales: http://www.libraryjournal.com/article/CA341766 The Librarians A now defunct power-pop band from Oakland, CA who used librarian stereotypes as part their shtick. For example, their band logo includes an illustration of a pair of black-framed glasses with one shattered lens. A photograph of the same motif appears on the back cover of their lone CD (properly clogging the used CD racks of the Bay Area). While they do have a song titled "Peace & Quiet, " I would have bestowed them all with "Superstar Reader" awards if they recorded a concept album where every song had a library theme.

How Useful Is the Boy in Striped Pyjamas About Telling Us?

How useful is the Boy in the Striped Pyjamas in telling us about the Holocaust? The Boy in the Striped Pyjamas, shows what life was like in Germany when the Nazis were taking over. The film tells us about two young boys with two different lives. The Boy in the Striiped Pyjamas is useful about some topics based in that time however it can also be unreliable in others. The Holocaust was mainly a target for Jewish people, black people, homesexuals, gypsies and the physically disabled, the mentally disabled and those involved in resistance movements against Hitler..The Jewish people were the main traget and this chatastrophe started when Hitler came into power. The holocaust was a bruital place for those people, they had no other choice but to do slave labour, such as people had to work in tunnels and starve to death. The Boy in the Striped Pyjamas explains the Age of the Victims. The film suggests that age tended to vary from young children to old men. This showed a unuseful report beca use during that time Nazis would kill those who were old of age and useless at working.This rule would automatically apply for those who were physically and mentally disabled. The Boy in the Striped Pyjamas only showed one child which meant the rest were adults. This was useful because sources show that there were the odd few of children but mainly adults in the concentration camps. This was because adults are more useful in terms of working. The film also explains the gender of the victims the film showed that there were only men in the camps. This was unreliable because other sources show that the gender also tended to vary with women also.However the sources did show that there were more men than women, so this meant men were stronger than women and could work more than women. There has been disagreement however whether or not men are stronger then women. â€Å"Men were stronger so would live longer†, I disagree with this statement because if women survived they would form a friendship with each other and therefore be able to support one another if they were sick and so could rely on each other. Also, the film showed what the work was like in the camps for a person.The film showed that people were forced to build and manufacture and they would all were the same uniform to represent that they were not and individual in the camps. The film also showed they were allowed to work outside of camps and work indoors with other families and work as a slave in their homes. This was reliable because everyone who were in the camp all had to wear the same uniform, and they did build and manufacture. But they also had to work in the tunnels , mining but mostly they worked until they died or were no longer fit to work and were sent to die.The rule that applied while working was if you could work well you would live, if not you would die. The film showed the small amount of food the people were getting. The young boy Shmall, explained the lack of food they were gett ing. The film showed Bruno bringing food to Shmall and how he ate it like a beast out of starvation. This was reliable because this represented that they did not get much to eat and some were forced to starve. Sources explains that each victim in the camp would get a slice of bread and sometime margarine and marmalade in the morning.Midday they would get potato soup and maybe a little of meat. Although the film did not show this they did show that the victims were skinny and many were starving. The film however did not show any escape from any victims in the camps. But showed that the electric fence surrounding the camp was that there was only one however sources show there were two so this meant, the Boy in the Striped Pyjamas was unreliable. Escape from the camps was almost impossible but I believe it was all done by luck. At least on stats, 802 attempted to escape and only 144 succeeded.The victims who did escape did not realise the consequences that 10 people, selected randomly, by luck, in the camp would be killed if one victim escaped from the camp. The film did not show any survival in the camp which shows that the film is unreliable. Sources show that surviving in the concentration camp had to fight against the harsh conditions they were living in. There was less food, space and less opportunity to be with friends or family. The labour was even more difficult and exhausting; there was constant punishment and stricter rules and regulations regarding every intimate detail of life.The Boy in the Striped Pyjamas also showed death in the concentration camps. They showed how men were beaten if they had done something wrong, spilt wine accidentally on the soldier and had used gas chambers to kill the people, by tricking them thinking it was a shower. This was reliable, however there were quotes made such as â€Å"Luck was the only reason people survived†, I agree with this statement because Viktor Frankl, worked as a kitchen carrier supplier, and how h e explained how he explained how without his job he wouldn't have survived by eating crumbs from the floor.There were other bruital ways of dying in the camps, some soldiers will allow you to starve to death by not giving you your breakfast or lunch, some others were immediately shot dead if they had done something wrong. I believe the Boy in the Striped Pyjamas is unuseful because it has given inaccurate accounts such as, men were the only people in these camps or no one escaped from the camps. It has however given some information such as how some people were killed in the gas chambers, but did not show how other people had died in more bruital impact other than a gas chamber.Also it has given an inaccurate account by implying that the people only worked by building and manufacuring when there were more jobs, working in the mines and dug holes for those who had lost their lives in the concentration camp. So summarising my view points I think the Boy in the Striped Pyjamas is unuse ful and unreliable, because it has shown an inaccurate account of what life was like inside the camp and in my personal opinion was much more brutal than they had shown.

A Problem Critical to the Education in the 21st Century Essay

In the 21st century I believe that inequitable opportunity is the most critical education problem. Inequitable opportunity impacts people of different racial backgrounds in various ways. It limits the knowledge a student receives, the rate at which they learn, funds available to the school, the students ability to succeed in the workforce upon graduating, it even affects the knowledge or lack of knowledge a student learns at home. Though this may affect the teaching staff in ways, minorities from a lower income family are the ones impacted most. These students often fail because they are not prepared for success. Students from a lower social class have fewer resources available to them; therefore they do not make it to the top. Schools in poverty stricken areas receive less funding, and this severely impacts the students. The school is unable to provide students with up to date technology, and the resources needed to compete with their peers from more privileged backgrounds. The school will not be able to provide ESL classes for Latino students. Students will more than likely drop out; the ones who actually manage to graduate will probably be less qualified to perform essential job duties. These students will not be as knowledgeable because they may be using outdated texts, and they are not able to learn how to fully utilize technology needed to survive in today’s workforce. Schools that are in a low income neighborhood do not have modern buildings, the school buildings are very out dated. The air conditioning and heating may not be working properly creating a very uncomfortable learning environment. This may discourage students from wanting to go to school and it definitely does not attract quality faculty. Another issue that impacts the student severely is the lack of parent participation in the education process. This is crucial to the development of the child from a very early age; it is imperative that a parent be involved in preparing their child for life, as well as reinforcing things learned at school. Education starts at home and moves to the public arena where social interaction, behavior skills and knowledge are enhanced. Poor parent participation may be the result of work schedules, transportation issues, language barriers, or suitable clothing. Once again children from low- income families suffer the most. Both parents may have to work just to pay the bills, and in some situations there is just one parent, forcing some students to help care of siblings at after school when they should be focusing on homework or studying. As the child ages less attention will be paid to the individual as class size increases, the number of teachers increase with diverse classes, and overall s ize of the school grows. At this point the child will need extra help completing assignments and requiring encouragement to continue the education process consistently and for the duration through some college. The parent is not exempt from the learning process because of inadequacy or exempt because of poor education. As briefly mentioned earlier, in this setting the teaching staff is likely to be under qualified, once again this impacts the student. By the teaching staff not being qualified the type of skill the students will learn will not be up to par. Classroom Managers should also be aware of how they are engaging their students. They should have high expectations of all of their students. There seems to be a lot of racial stereotyping in minority communities. Teachers should know that all Asian students aren’t smart and that all African American students inferior learners. If teachers establish a high expectation of learning from all of their students and expect all of their students to do well then those expectations will be seen by the student. Students are then able to work at their highest potential and are not limited; a teacher should believe that all students are capable of learning at a higher level. The teacher of the 21st Century need to be more culturally responsible and they need to be more aware of what is going on in the classroom. Educators need to be trained in a way that is going to be more beneficial to the educational process as a whole. For example if a teacher has a classroom where the majority of the students are not being successful then that teacher and/ or teaching techniques should be reevaluated. The classroom is not a place where a student is just given work to perform and the teacher is detached, the classroom of the 21st century needs to be an interactive classroom where teachers and students comes together to share ideas, and engage each other in the learning process. Unless a Teacher can step out of the conventional box and begin to assess themselves and what they actually bring to the classroom, it will not evolve. Teachers should interact with students on a more personal level in the classroom and get to know their students as individuals; some children can get lost in the classroom for a number of reasons; including personal problems at home, and learning disabilities. By being involved more with the student’s teachers are better to adapt to a student that is having problems because they are unable to read well, or a student that is simply having problems seeing the board. Without establishing some type of a relationship with the children it is very hard for a teacher to recognize the problems students are having and how to effectively deal with these problems. Just because a student is unable to keep up with fashion, technology receives free lunch does not mean that this student does not have the ability or the will to learn. There are successful people that grew up in poverty, and have gained success through hard work and education. Everyone should have the same opportunity to receive quality education. Students are taught that education is the key to success, so how can one succeed when the education is not equal to their peers, the ones they will be competing against for their spot in the future. Education is the poor man’s dream to a better life. With minorities and Latinos making up a large amount of students in school the effects of inequitable opportunities has a larger impact on them. Students who come from an inferior social-economic level are just as motivated as students who come from a higher social class. You have Latinos who hardly speak English and are attending schools that are incapable of accommodating them; therefore they do not earn a degree and are forced to take a low paying job. â€Å"Status† may have an impact on a student in a social environment, but in the educational system this should not be a factor. The students from a lower social class are being prepared for failure, while the students from a higher social class are being prepared for success. In the 21st century I believe that inequitable opportunity is the most critical education problem. Recognizing the problem is the first step, however we as a society need to find solution on how to better level the playing field in the educational comm unity in order to make schools work for everyone. One thing we can to is to not only encourage proper funding for schools in low income areas but to also make sure that this funding get appropriated to do what is needed in order to make sure that the children have a proper learning environment. Bills and referendums continue to be passed in education s in order to make sure that schools are up to par but sometimes this money does not get to the prosper schools. Some schools get new buildings and a/c systems while other schools just get paint. We need to come together to demand to our elected officials that something be done about the conditions of certain schools. We need to make sure that these school schools have the materials that they need in order for them to produce successful students. Books need to be provided to every student not only in class but also at home as a reference for homework and studying. Computers need to be provided in these schools so that the students don’t fall behind on technology and become inferior to their peers. We elect these officials and we need to demand that they begin to look out for the betterment of our schools. We should go online and see how they are voting on the issues that affect us. If they are not pushing the type of educational reform that we need in our communities and in our school then we need to elect someone who will. Parents need to become more involved in their students learning. We must understand that a lot of parents are working, and most low income households are being led by a single parent; we need to find a way to get these parents involved to help their children so that they don’t continue to fall behind. Even if it’s just educating them on the process of following up with their elected officials and making sure they vote and their vote counted and is heard. Opening up the schools for parent participation and PTO and PTA meeting on a weekend rather than on a school night would make it easier for parents to become more involved. Also, schools could try social networking, and sending up dates to parents Facebook or Twitter pages to keep them up on what’s going on in the schools. This is a new era and the American household has changed and the educational sytem needs to keep up in order to keep these parents involved and up to date on what’s going in their child’s school. Teacher also need to be developed in the classroom and become more responsible for what is going on and have high expectations for all of their students. This will ensure that all student as are working to their best ability to learn. This can be done by giving existing teachers additional training and giving new teachers the training they need to be successful in the 21st century classroom.

Marriot and Body Shop Aims and Objectives Essay

introduction Marriot is an international brand however the purpose of this controlled assessment, they will be my local business known as London Heathrow Marriott-LHM. Marriott is currently a private limited company (PLC) and has two other private investors as owners of the company. The Marriott hotel was founded in 1993 and is located in Harlington, Hayes. Currently its labour turnover for the month of September (2010) is an increase of 10.1%. Marriott acquires approximately 133,000 employee’s world wide and between 8,000-9,000 employees in the UK. My other local business is The Body shop. The Body Shop is an international business Definition of Aims The long-term goals a business wants to achieve. Goals that a business wants to achieve to be successful. Explain what aims are Definition of objectives The specific steps taken by a business to achieve a goal Objectives have to S.M.A.R.T, this stands for: * Specific * Measurable * Achievable * Realistic * Time Marriott’s aims * Guest Satisfaction Superiority * Marriott Profitability & Owner Return on Investment * Associate Satisfaction Marriott’s objectives * GSS (Customer Target) 75% (satisfied with overall service) * Sales turnover of  £20m per annum * Labour turnover less than or equal to 25% Summarising Marriott’s aims and objectives Marriot have set themselves three aims that they hope to achieve. These three aims vary from making a profit on their investment to guest and employee satisfaction. Marriott’s first aim and objective focuses on customer satisfaction. They are going to meet this goal by being customer focused and meeting customer needs. To achieve this they will do everything in their power to keep their customers happy to give recommendations to other people and for them to keep coming back to their hotel. They need to deliver the â€Å"wow factor† by providing the best quality of service. They intend to meet this aim by encouraging their guests to complete a â€Å"Guest Satisfaction Survey†. To achieve their aim they need 75% of their customers to be satisfied. The management team reviews all these surveys to find out what they need to improve on to make the hotel and make it the best in the industry. They also focus on associate satisfaction which focuses on the employees. They are striving for labour turnover less than or equal to 25% therefore Marriott hope not to lose more than 1 in 4 of their employees. They aim to make employees satisfied by ensuring their staff is happy. They will achieve this aim by motivating their staff and rewarding them with staff benefits for example LHM offer â€Å"Valuable room rate, food and beverage, and retail discounts at global Marriott locations.† This gives the employees the feeling that Marriott cares about them. Also the amount of pay that is offered by Marriott is higher than most equivalent jobs. This makes the employees want to stay as they know that there is a very slim chance that they will find this amount of pay anywhere else, or they may not get the same amount of bonuses-motivating them to do better- The want the communication between the staff and Marriott management to be strong as this gives the employees the sense that they are involved within the business. Their third aim and objective focuses on Income and money made. Marriott want to make a profit and have a sales turnover of  £20m per annum.

The Negative Effects of Casinos

As stated in the â€Å"Harvard Mental Health Letter, pathological gambling has 0 symptoms, which include :†preoccupation with gambling, gambling with increased amounts of money, returns to gambling after losing money In order to recover the losses, and asking others for money to solve financial problems caused by gambling. † According to calendaring. Com, â€Å"about 2. 5 million adults in America are pathological gamblers and another 3 million of them should be considered problem gamblers, 15 million adults are at a risk for problem gambling and about 148 million are low-risk gamblers. There were many sociological and psychological tests done on the subject f casinos and gambling addictions; these tests support my final thought and opinion, that casinos will do more harm than help; although, I will show both views. They will cause many problems and may even cause a domino effect starting with personal problems, than expanding to sociological issues, and leading to gove rnmental tragedy. We will first look at the earliest effects of casinos which are the ones that effect Americans personally. When one enters a casino for their first time, they don't realize the trouble lurking closely behind them.Upon premature gambling problems, most addicts don't even realize there Is a problem. Herbert A. Bloch stated In The American Journal of Sociology. â€Å"Its danger Lies In the fact that It interferes with the normal assumption of responsibility which organized society compels. Simply implies that gambling most dangerous attack is the one in which impairs our Judgment of social and psychological norms to the point where we cannot make responsible decisions. Because of this, addictions may become larger and may bring on other addictions, such as alcohol and drug abuse.Casinos cause financial problems In many lives of Americans, which also leads back to drug ND substance abuse because people use these to cope with their problems. An example of the snare of addictions, which originate from the habit of gambling, would go hand and hand with a person who reads the literary work, The Lottery, by Shirley Jackson. In the story the reader has no idea of the horror involved with the lottery; they assume it to be a normal money type reward, until the devastating end of the story, when the winner Is to be stoned.It Is Important to heed warnings and place Limitations when going to a casino, because If a casual drinker can turn Into an alcoholic, a casual gambler can turn into a compulsive gambler. Scripturally gambling is wrong, and many Christians believe it isn't a godly thing to do because you may win some other person's money that they over spent and now have no bill or grocery money. In 1 Corinthians 8:13 it reads, â€Å"Wherefore, if meat cassette my brother to offend, I will eat no flesh while the world standees, lest I make make my brother to offend. KAVA)† They also believe that It Is wrong to be a bad example to others, so If a Eternal or Tamely memoir NAS Ana a gambling problem In ten past, Its Test to not associate with that person in a casino so they will not have any temptation. Gambling significantly affects the finances of many Americans. Casinos bring in over 500 billion dollars a year as stated by calendaring. Com. Sometimes the gambler puts his/her addiction before what is really important in life, causing problems with work, friends, and even family.Spending budgeted money is a big issue within a family and causes problems, but an even bigger argument is the fact that the time used in gambling is being robbed from the people who truly deserve it, like children. MUSM Kayak states in an article on canticles. Mom, â€Å"the spending of money is not the only devastating affect that this can have on kids, they can also suffer from other kinds of abuse such as verbal, physical and emotional. As these people tend to suffer from an enormous amount of stress, which will effectively make them angrier and more anxious. The psychological effects of gambling cause problems within the family, which may potentially break it up either by divorce or child services. The stress put on the gambler can come on so strong, that they feel helpless. They feel like there is no way out of the trap that they are in and resort to suicide. Many studies are now being done on this subject, to see if the rise in suicide ratings has any correlation with the effects of casinos, though there are many cases that prove this to be true.A wider view of how casinos negatively affect Americans is by taking a look at the reactions within societies. A society is the bigger picture which is less personal, and more collective. We can view society as the people, areas and environments surrounding the casino. First, we see the amount of crime increase within and surrounding casinos. This has been proven recently in Bangor, Minneapolis, where he local paper â€Å"Bangor Daily News,† had an article stating, â€Å" In 2008, crime increased to 65. 07 per 1,000 and this year [2010], the rate eclipsed 70. The increase was due to a casino, and they came to this conclusion, because other areas near or surrounding Bangor, had decreasing crime rates. The main 5 crime rates that increased were homicide, domestic violence, robbery, forgery, and drugs. Prostitution is also a big factor around casinos. Murders and armed robberies happened more often in parking lots of casinos due to stalkers inside of the casino, that follow big winners. The crime helps with the dilapidation of neighborhoods, which is basically the deterioration of a community. Neighborhoods look run down, and are filled with litter.When this occurs, property values go down, homes become abandoned, drug propaganda elevates (also with the crime rates), and the neighborhood is considered to be, at all costs unsafe. Traffic elevates in areas that contain casinos causing higher averages of pollution. Gas franchisers increase the prices of ga s and fuel around casinos because of the guaranteed flow of traffic. Another bad result in society is an increased rate of accidents, hit and runs, and Duds; all caused by either anxiety, rage, or being under the influence of alcohol or a substance.The biggest view to see how casinos negatively affect America is to look at its government. Look and view how the economy is, in today's realm, and answer to yourself if casinos can help. With people using their paychecks at casinos, they fall deeper into debt. People these days want easy money, but gambling is an extremely risky way to retrieve it. Especially because people believe that they have a 50/50 chance at winning, when in reality (it has been proven) to actually be 60/40- 70/30 in en salons Tabor. Casino taxes are extremely sustainable, Delving at ten Nell rate AT 21. % back in 2008, nevertheless, we have yet to see improvement on roads and in schools, which are where the tax payers wish see the funds go the most. And while fund s have Just been mentioned, I must bring up the concern for loss of budgeting in many cases, by way of casinos. Because of crime, many more police officers are needed in the surrounding areas of the casino. Especially for the ones opened for 24 hrs. The funds used to pay for police officers come from federal and county funds, which could be used in more important fields. Unemployment rates have sky rocketed lately.And it has been true in many cases that unemployment money has been used within casinos, leaving families in need, bills unpaid, and debts accumulating and some even with interest. Sadly the unemployment rates continue to rise and extensions continue to be placed on many cases. Casinos are only hurting the financial of the addicted. Many families are also on welfare, due to the lack of money. And with the numbers of both unemployment and welfare rising, we can only expect our nation's economy to go into a bigger deficit. If anything, we should raise gambling taxes. It is t he right of an American to go to a casino.Most people who do go into a casino do not have a strong or addictive gambling problem. It is their individual decision which they are free to make. If humanity could not make decisions, we would have a world or society like the one in the literary work of Any Rand, Anthem, which states,† We are one in all and all in one. There are no men but only the great WE,One, indivisible and forever. (19)† Americans have many freedoms, it is possible for us to drink, to use medicine rugs, and even to gamble, but many Americans have proven that strength is needed when engaging in any of these.Just like the alcoholic starts off as a casual drinker, it is very possible for a casual gambler to become a pathological gambler. Casinos do provide Jobs for many Americans, but it robs the Americans that do have Jobs. The basic argument that faces us is freedom verses right/wrong. That is up to you as an individual to decide. To conclude, you have see n the negative effects that are overcoming many Americans. Many problems, in which are controllable, but even more importantly avoidable. The only way to actually avoid these problems would be to eliminate casinos all together.Fewer financial problems within the family, society, and government is a great plus; greener, cleaner neighborhoods with less traffic will help society; fewer men and women on unemployment and welfare, and less police needed in and around the casinos area will provide more money for our nation eliminating some devastating debt. I believe that the best option for America would be to prohibit the building of anymore casinos and to begin shutting down the ones that are open now, starting with the larger ones.
