The heat energy produced by propanol Essay Example

The heat energy produced by propanol Essay Example The heat energy produced by propanol Paper The heat energy produced by propanol Paper The energy released by a fuel depends on two things. Firstly the number of bonds to be broken and made and secondly the type of bonds involved. Therefore from the preliminary work I can see that propanol has similar type bonds to ethanol, but it has more of them. This means that proponal will use more energy to break the bonds and; therefore more energy will be released to make more new bonds. Also, the greater the surface area and the greater the force of attraction between the molecules, will make it harder to vaporise. Therefore more energy will be released. Fair Test I would like to gain the most reliable results possible using the equipment and conditions provided; therefore I will have to consider certain factors, which if I do not control, may enforce my results to become less reliable. I will, * Keep a constant water temperature at the beginning. * Keep the distance of the copper can away from the flame at 5cm. * Have a constant water mass. * Keep the temperature from which the experiment is terminated fairly constant. * Stir the water with the thermometer before each temperature reading, which will distribute the heat evenly. Results Fuel Mass of Fuel Used Average Ethanol Analysis I will use the averages for ethanol and propanol to work out the total energy transfer and then I will use this to find the mass of fuel burnt per mole. The workings below show what I found out and what this suggests. Ethanol Q = M x C x t The letter Q is the energy in joules and what I want to find out, M is the volume of water in the copper can, C is the specific heat capacity of water and At is the rise in temperature during the experiment. All of these were kept the same throughout the experiment; therefore, M = 100cm3 C = 4. 2 t = 200C This gives the equation,Heat produced. The mass of ethanol burnt is 1. 4g and the relative molecular mass is 46, which I have already worked out previously. In order to work out the number of moles in 8400KJ I will use the equation, Number of Moles = mass/Relative Molar Mass If I put these numbers into the equation to give, Moles of ethanol burnt = 1. 4g/46 = 0. 03 moles. I will then use this to calculate the energy in one mole, 8400/0. 03 = 280000J = -280KJ Propanol I will use the same equation using the same numbers as before as they were kept the same in this experiment as well. This should give,Heat ProducedThe mass of propanol burnt is 1g and the relative molecular mass of propanol is 60, which I again worked out beforehand in my plan. I will use the equation, Number of Moles = mass/Relative Molar Mass I will put the numbers in the equation appropriately to give, Moles of propanol burnt The above figure can be used to work out the energy in one mole0KJ I did not use 0. 4 for the propanol average, because it does not follow the general trend; therefore it is anomalous. If I had included this result it may have affected my results slightly. The results that I obtained clearly show that the propanol did have the greatest energy loss; therefore my prediction was correct and theoretically my preliminary work was very successful in helping me gain the correct prediction. This is shown whereby for ethanol the energy give out per mole is -280KJ, whereas propanol gives out a slightly bigger -420KJ. From this experiment I have learnt that if there are too many carbon atoms present in a fuel then the energy given out as heat through combustion is increased, whereas if there are too few carbon atoms then the energy given out as heat from combustion decreases. If I compare my results with my preliminary work there is an immense difference in figures, whereby for ethanol the energy produced from one mole using the scientific figures is -1031KJ, whereas my results show that there is -420KJ of energy released. Also the scientific results for propanol are -2076, whereas my results show that for proponal -420KJ of energy was released. This significant difference was probably due to the extreme mass of heat loss during the experiment from the copper can, the spirit burner and the water; therefore less heat was transferred to energy. Also average bond energies shown in the data book were taken at 250C, whereas I took my results at a temperature of 200C, which means that a higher temperature the molecules would have had more energy as the bigger the temperature the faster the reaction; therefore more energy would have been transferred as heat after the breaking and making of the bonds. Evaluation I think that my experiment was fairly successful considering the limited equipment and conditions, as I managed to gain a set of fairly reliable results in order to draw a firm conclusion. There was only one anomalous result, which happened when testing the propanol whereby there was a result of 0. 4; therefore I did not include this in my average taking. This could have occurred for a number of reasons these are, The amount of water put into the can may not have been measured completely accurately because of the way the level of the water is seen in the measuring cylinder.   There may have not been a totally consistent height above the spirit burner. The spirit burner was not covered up during experiment; therefore the fuel could have evaporated. The length of the wick varied.   Heat could have escaped out of the sides of the spirit burner during combustion.   The copper can meant that it absorbed and transferred heat well but it lost heat to the air as well. These reasons could have had an slight effect on my results overall, whereby it will have made my results lower than the theretical results, as shown in my analysis. If I were to do this experiment again I would, Weigh the water in the copper can using burette instead of a measuring cylinder. Measure the distance between the can and the sprit burner between each fuel burnt.   Cut the wick to the same length after each fuel is burnt.   Insulate the copper can at the sides. User a Bomb Calorimeter so that draughts can be prevented and so that there is restrictions to the heat lost. The diagram below shows what the bond calorimeter would look like and how it would be set up. I think that despite the problems that occurred I still managed to gain a fairly reliable set of results in order to imply whether the energy loss for ethanol or propanol was bigger. If I were to experiment further I could experiment with a much wider range of fuels to see whether their energy loss is bigger then propanol. Also I could investigate other factors that affect the energy loss from combustion, such as, the length of the wick, the heat source and the heat capacity. In doing this I can broaden my understanding in this section of chemistry.

Quantile Hedging Dissertation Example | Topics and Well Written Essays - 8250 words

Quantile Hedging - Dissertation Example As the report dceclares investors, security analysts, investment bankers, portfolio managers, bond-rating agencies, and corporate financial analysts are concerned about the insecurity of the returns on their investments. To minimize the risks of losing in the financial market, hedginga is done by these market traders. Hedging is a method to protect one's investments. Financial derivative instruments made hedging of these risks possible. Hedgers can sell the risks to speculators, or buyers of risks, but only when these risks show some form of stability. According to the report findings when the price of the securities increases, the trader gains profit from the main securities bought, but exhibits loss on the securities that were sold short. On the other hand, when the industry declines, the trader will earn from the short sold securities and lose from the long ones. Thus, hedging also brings risk when the securities appreciate in value. But the possible loss is not as much as when hedging is not done. The classic practice evolved into more sophisticated means as new mathematical tools or models are introduced. All types of hedging techniques generally involve distribution between the actual market value and theoretical value, and aim to gain profits when these values converge. Common types of hedging are applied in insurance, credit risks, foreign exchange and equities. An option is a contract which gives the holder the right to buy or sell stocks or securities either at a given price or a specified period of time but without any o bligation. These assets are called derivatives because their value is derived from another investment's worth. Call options give the holder the right to buy the securities while put options give the holder the right to sell. Option pricing strategies can be traced back in history since about 1877 when a book entitled "The Theory of Options in Stocks and Shares" was written by Charles Castelli. He presented in his book the speculation and hedging aspects of options but there was no significant theoretical base. There were several more dissertations done since then that presented the analytical valuation of options and pricing models (Rubash, n.d., p.3). The modern option pricing models being used now were based on these dissertations done decades ago. These option pricing models common to traders and analysts now are the Bachelier model, Black-Scholes model, Merton model, and the Cox-Ross-Rubinstein model or the Binomial Option Price model.

Juvenile delinquency Research Paper Example | Topics and Well Written Essays - 2000 words

Juvenile delinquency - Research Paper Example Statistics showed that the young people are the ‘most active part of the population involved in illegal activities’ based on different forms of risks factors such as peer pressure, lack of parental or adult guidance, etc. thus, resulting into different forms of crimes such as substance abuse, and even murder in the most serious case scenarios (2005). Juvenile delinquency is an issue that affects both the legal and social aspects of the society. Although the problems related to delinquent behaviors can be rooted to the biological risk factors and parental supervision, the solutions undertaken by the society transcends the boundaries of personal and family life. The legal aspects and the establishment of the juvenile justice system can be considered as the main intervention established by the social and political leaders to resolve the problems related to juvenile delinquency. Juvenile justice is directly related to juvenile delinquency on the precept of finding solutions to the problems related to the latter. The main focus of juvenile justice includes the crimes that are committed and/or affected the youth. These cases had been recorded through history and each period had established certain rules and guidelines to handle these types of problems but the cases of problematic youth still continue. Based on the work by William Sanders in 1970, it had been de noted that juvenile offenders of the law had been recorded for 1000 years and such problems had been known even earlier (Shoemaker and Wolfe, 2005, p.3). The juvenile justice had started prior to the formal establishment of juvenile courts. During the early part of history, e.g. the era of feudalism, social control can be considered as the most stringent in every aspect of the society. Due to the social structure, the family was considered as the basic unit of social control. But

The Role of Medical Laboratory Assistants Assignment

The Role of Medical Laboratory Assistants - Assignment Example But the main duty of MLAs is to process the sample so the MLA should have a sound knowledge about the sampling and the processing techniques as well as the local recommendations of the regional medical legislative authority. The main principles of planning a test include the propose of carrying out the test, the knowledge of the clinical suspicion for a particular disease. Then the time frame of performance is planned followed by the list of the equipment and the chemical used and then the standard procedures for the investigation are gone through in detail to exclude the possibility of missing anything. Basically, the responsibility of accurate and timely reporting of test results lies on the personnel working in the laboratory as there are many problems which can arise even before the sample has undergone the analytical process. These errors can only be tackled properly if the prior understanding of the process, as well as the capability to identify any error in these processes, is present in the MLAs. In addition to this, controlled and correct interpretation of results needs a comprehensive knowledge of analytical, biological and pathophysiological variability and the extent of this change. There should also be sound knowledge about the time span in which changes can occur in the sample resulting in the variations and errors in the final results. Reproducibility shows the relation of the results of the tests carried out with different operators, test apparatus and in different laboratories, it is usually expressed in the form of standard deviation. It is directly related to the accuracy of the results and MLAs should be able to reproduce the results which are accepted worldwide. The process review techniques should be quick and easy as it will save the time of quality control supervisors.  

Critical Response Teen Magazines A Critical Analysis English Language Essay

Critical Response Teen Magazines A Critical Analysis English Language Essay Magazines aimed at the young teenage women market may give the impression of being a girls best friend. Of course, like everything, they have their strengths and weaknesses but do the strengths outweigh the weaknesses? It seems more likely for the negative effects of teenage magazines to be more prominent than the positive effects but is this really the case? This response reviews the way teenage magazines address issues relevant to young women today, especially from the point of view of promoting healthy body image, safe sex and leading social justice issues. All these aspects are emphasised by techniques used in the composition of these magazines with article structure, visual collages and informal language being the most common. Are the issues they cover and the extent to which they cover them appropriate for their readers? Teenage magazines, such as Dolly and Girlfriend, are often the first place teenagers turn when they have a problem and that is when segments like Dolly Doctor  [1]  are most commonly used. This reinforces the need for the magazines content to be appropriate for their readers; however, this is not always possible. Magazines, such as Cleo and Cosmopolitan, are in a difficult position; whilst they are aimed at the young adult market, 18 to 35-year-old women, a large proportion of their readers are between the age o f 14 and 17. As reported in the respective magazines readership profiles, 35.16 per cent of Cosmopolitan readers  [2]  are aged between 14 and 17 and 29.11 per cent of Cleo readers.  [3]  How does this effect the teens who read these magazines? It appears that these effects are positive, such as encouraging their readers to exercise, as well as negative, for instance lowering their self-esteem. Why are teenage magazines so popular? Issues facing teenagers Teenage magazines play an important role in the average female teenagers life. They provide a wide range of information, from social issues such as smoking and drinking, to issues of a less important nature, such as what to wear to the formal, or how to talk to boys.  [4]  It is, therefore, important that they address the relevant issues teenagers face in society today. One of the biggest issues addressed in teenage magazines is sex, and more importantly, safe sex. The impression you acquire when you pick up a teenage magazine is that they assume that if girls are not sex savvy then they want to be.  [5]   One teenage reader asked the question concerning Chik  [6]  magazine: wheres all the sex stories?  [7]  This simple question supports the theory that teenage magazines are not necessarily successful for the correct reasons. Amongst some groups in society, such as the Christian churches, such articles are often perceived as immoral. It also makes these acts seem more common in society, which is not necessarily true. In fact, 80 percent of 16 year-olds have not had sexual intercourse but by the age of 18 theres a 50 per cent probability that they have.  [8]  Being a virgin is generally criticised by other teenagers. Despite the fact that magazines promote safe sex, research has shown that safe sex does not exist unless two virgins are having sex for the first time and remain with each other for life.  [9]   On the other hand, these magazines run articles on what their readers want to know. If Dolly magazine receive a letter asking for help about not wanting to have sex, they will run an article about abstinence. Or if they receive a letter about date rape, they will run an article about date rape and what to do about it. In the same respect, if a reader asks Dolly, what is masturbation? they will respond with an appropriate article.  [10]   There seems to be a common perception that reading teenage magazines has contributed heavily to readers low self-esteem. As a result of this perception, today teenage magazines seek to promote a health body image. Dolly magazine has a specific section in every issue called the Body Confidence Club  [11]  that is dedicated to motivating teenagers to be content with their body. This ranges from advice on exercising and meditation to healthy eating. Often it will include real-life stories to help teenagers to believe if it worked for them, it can work for me! The deputy editor of Dolly magazine said: We never publish diets or ever say that a girl should lose weight, its only ever about toning up if thats what you want to feel better about yourself.  [12]   The Body Confidence Club is a reader forum where Dolly talks about a body issue and does it in a way that is inspirational. Stories will reflect the problem and show solutions, stimulating teenagers to think that they can change too. Publishing articles on healthy body image next to fashion spreads glorifying all that is tall and skinny  [13]  can have a negative effect. What girls need to remember is that Marilyn Monroe was a size 14 and she was still considered beautiful.  [14]   Even Cosmopolitan has dealt with the issue of body image, introducing the Body Love Initiative in October 2001. This policy states that Cosmopolitan will use models from size 6 to size 16 in every issue, as well as all races. Alongside the models, Cosmopolitan will not publish a diet and has not done so for around seven years. They also ensure that their advertisers do not place unnecessary emphasis on the need to be skinny and consistently publish articles to help readers feel more confident and love the skin they are in. These guidelines were put into place after readers became outraged over a photo shoot, Lingerie Gets Real, featuring women in their underwear.  [15]  Cosmopolitans philosophy is: Healthy eating, healthy body image but being within your healthy body weight range all about feeling good in your own skin.  [16]   Another issue addressed by these magazines concerns popularity amongst peers. This is an important issue in the minds of teenagers, especially in the school environment. The common perception that you have to be cool to obtain the attention of a boy increases the pressure of becoming popular. To quash this assumption Dolly magazine focuses on the fact that popularity is not as important as being confident. Therefore they run stories about how to talk to people, both boys and girls, and how to be more confident in different situations.  [17]  However, confidence is just one part of it. If a teenager does not feel popular she is less likely to be confident. So it is important to address popularity as an issue of concern. Mental health and wellbeing are important issues to address for teenagers. They need to gain understanding of the causes, occurrences and management of these disorders. Without this knowledge there are often misconceptions about disorders such as schizophrenia and depression. Suicide, bipolar disorder, anxiety disorders and self-harm are all common topics of discussion in Dolly magazine because of the many letters received requesting information about certain mental illnesses. The deputy editor of Dolly states that: In all of those stories we do talk to experts about the issue and get information that the girls can use.  [18]   Cosmopolitan, on the other hand, always runs feel-good articles in the magazine each month to help their readers overcome their own anxiety and stress  [19]  but they do not run articles to increase the awareness of mental illnesses. Illnesses such as schizophrenia and bipolar disorder are rarely mentioned in Cosmopolitan. Physical impairment is another issue that needs to be dealt with. This is to ensure that teenagers acknowledge that people with physical impairments are not different. Dolly often publishes articles on the life story of someone with a physical impairment to show the readers that despite this impairment and the obstacles in their life they still live normally and they are like any other person. However, Cosmopolitan and Cleo fail to cover issues about physical impairment. How magazines are composed How do magazines persuade people to read so many articles and view the visual images constructed in each monthly issue? This is achieved through the language and visual techniques that are used and accentuated to capture the attention of the reader. These include structure, interviews, language features, pull-quotes, rhetorical questions and visual texts. Firstly, the structure of most feature articles is changing. They are beginning to be separated by many sub-headings. By using sub-headings it allows the reader to go straight to the part of the article they are particularly interested in. For example in the Dolly article, The Rise of the Straight Edgers,  [20]  if a person knew what a Straight Edger is, but was wondering where the name came from they can go to the sub-section, Whats with the name?  [21]  Or if they wanted to find out more, they are directed to the section, Wanna know more?  [22]  This means that a person can get what they want out of the article quickly without having to read the entire article. The types of articles also vary from stories, interviews and notes. Stories are effective in entertaining as well as informing. The investigation into the statistic that 1 in 5 women will experience violence during pregnancy  [23]  is informing the reader about the risks of violence during pregnancy as well as telling the stories of women who lost their lives at the hand of the father of their unborn child. The use of interviews creates the impression that the reader is communicating with the interviewee, and not reading it second hand. An interview, such as Tammin Sursoks subtitled, The first time I ,  [24]  gives the reader the feeling of having a conversation with your best friend about the first time you kissed a boy had sex fell in love à ¢Ã¢â€š ¬Ã‚ ¦Ã‚  [25]  This creates the effect that the reader is getting to know the celebrity personally, instead of just reading a magazine interview. The use of first person also emphasizes this in the mind of the reader. This approach is taken in most interviews in magazines in an attempt to personalize the article for the reader. Notes allow the reader to go straight to short bits of information. In Rags to Riches  [26]  the reader can quickly obtain small pieces of fact from the spreadsheet of information. These text formats allow different readers to access the information that is of specific interest to them. The language used amongst teenage magazines is informal, conversational and full of jargon and slang. This is because these magazines try to speak to the reader, not speak at them. You could imagine that if one of these magazines happened to use formal language it would appear as though the magazine is a text book and very serious. Informal language creates a much more carefree approach to topics of discussion positioning the reader to relate more easily. For example, if this sentence: When you look at Jade, she strikes you as just another spunky chick, in miniature  [27]   was written formally it would say something along the lines of: Upon viewing Jade, your first impression of her would be, a short but fashionable woman. Instead, using informal language helps to keep the teenagers interested and they are more likely to read and understand what is being said. It also fits in with each magazines philosophy  [28]   to be the readers friend and adviser. Jargon and slang reaches the teenagers on their level. In this particular sentence slang is adopted strongly and still manages to communicate its message: You probably heard Paris [Hilton] threw a tanti when she saw her porn vid being sold by her local newsstand owner  [29]   Words such as tanti and vid are slang for tantrum and video. The purpose of this language is to relate to the teens by communicating to them using their own jargon. Emotive language is used to create a response in the reader and is present in sections like Dolly Doctor  [30]  and Sex, Body and Friends Advice  [31]  . Its intention is to convey the message that the writers at each magazine truly care about the issues people are asking about and they offer genuine advice to help their reader. When Girlfriend Advice was questioned about bullying, their response was: All of us here at GF [Girlfriend] feel very strongly that you have a right to feel totally safe at school.  [32]   The expression of concern for the girl being bullied helps the girl to believe that they really care. Dolly magazine also does the same thing. When Dolly counsellor, Louise Redmond, was asked about whether there is something wrong with a girl who keeps being excluded from her friendship groups plans she responds: Theres absolutely nothing wrong with you! Hard as it is, dont take it personally.  [33]   As a result of this expression of kindness and concern the person asking the question then feels compelled to follow the advice handed out to them by the magazine. The use of second person addresses the reader. Its inclusiveness embraces each readers concerns. Pull-quotes are used within articles to compel you to read an article. A pull-quote is a quote from the article that is selected and highlighted amongst the text in a different coloured and larger sized font. This device is used to draw the readers eye to the page. The quote is chosen on its strength and whether or not it is interesting, funny, exciting or riveting.  [34]  For example, in the article titled, Im a teenage mum of three,  [35]  the pull-quote, All of my friends lost their virginity before me, but I wanted to wait until I felt ready to have a baby  [36]   interests the reader into reading the article to find out why this teenager has three children by the age of seventeen. This is effective in attracting interest and attention to the article. However, other pull-quotes can seem completely irrelevant to the story. For example, an article titled My parents are both blind  [37]  with a pull quote: If someones playing kickball I run off coz Im scared about it hitting me  [38]   This pull-quote seems completely out of context, however, by causing confusion about the article teenagers are more likely to read the article. If only to find out how that pull-quote relates to an article about something perceivably different. Rhetorical questions invoke thought about the issue being addressed. If the issue is not a well-known topic questions such as: Does he love it? Hate it?  [39]   strategically placed at the beginning of the article encourages readers to engage in reading and contemplating the article. The composers of the magazines have, therefore, reached its purpose to persuade people to read their publications. Emphasised questions help to make the reader focus on what an article is addressing. The majority of the questions asked are answered within the body of the article. What can you do to stop the symptoms?  [40]   is answered, Learn new and better ways to deal with stress. Eat a varied diet and avoid foods that have a high fat content  [41]   This allows the reader to gain closure on the topic of discussion. If you were to pick up the latest Dolly magazine to find that there were no pictures at all, what would you think? Without images these magazines would have no appeal, people would just walk straight past them in a shop. The problem begins at the appropriateness of these visual images. Often an article would not survive without images or be overlooked if it was not for the suggestive images surrounding the text. The most prominent visual technique is a collage, especially on the front cover. It is the most effective way of putting a lot of information into a small space. A collage is used in Dollys Style section  [42]  and presents to the reader four celebrities, their fashion style, and the clothing articles and accessories they can obtain to achieve the same fashion style. Some articles, such as How Old Is She?  [43]  , could not exist without pictures. How do you demonstrate that a person looks young or old for their actual age without images? These pictures, however, seize the readers attention and intrigue them to find out how old these girls really are. Other pictures are used to tease the reader into reading the article. Images such as the one in Great Places To Kiss  [44]  catches the readers eye and provokes them to read the article. Even the image for the article Stop Texting Me!  [45]  provokes the reader. They see a girl with a mobile phone and quickly examine the article to see if it is of any interest to them. In Cosmopolitans fashion workshop  [46]  visual images are essential to explain why you should not wear certain types of underwear for different body shapes. However, Cosmopolitan has taken some poetic licence. In the images showing the reader what not to wear they place the model in an unflattering pose and appearing self-conscious. This creates the effect that it is not something the reader would want to wear. Of course, when the model is wearing what ultimately looks better she appears to be happy and confident, posing with a smile. A recurring way of presenting photos is in the notice board style. Each photo has a thick white border and a paper clip or thumb-tack in the corner, giving the effect that the photos are up on a notice board, attached to a personal profile or even part of a personal notebook.  [47]  Personalising these photos involves the reader in the magazine and creates a carefree atmosphere. Consequently, the combination of these techniques makes a teenage magazine intriguing to the reader. This results from being positioned by the composer in a location easily accessible to read or view the text. By making these magazines intriguing and easily accessible allows the magazines to sell many copies of each monthly issue. Magazines and Appropriateness Many people tend to focus on the negative aspects of what teenagers are reading in magazines. Christopher Bantick, The Age journalist, wrote: Besides the heavy emphasis on sex and problematic sex at that teenage girls magazines capitalize on adolescent insecurity.  [48]   Although this is accurate, Bantick could be optimistic and, instead of reinforcing common beliefs about magazines, he could address the fact that these magazines do aim to reach out to teenagers at their level and help them with their insecurities, whether that would be about sexual intercourse or not. Magazines have implemented sections within the magazines where their readers can write in to ask for advice  [49]  about something they feel uncomfortable asking their parents or even their friends. Many parents do not like what their daughters are reading in these teenage magazines, as evident by the Your Say section of The Age,  [50]  but many more are actually dejected that their daughters are growing up too fast and interested in such topics of discussion. Articles regarding Sex Exotica  [51]  would seem inappropriate for a 14-year-old female to be reading. Such an article may be appropriate for Cosmopolitans market audience, 18 to 35 year olds. However, the editors should take into account that a large percentage of the readers, 35.16 per cent  [52]  to be exact, are aged between 14 and 17. However, if Cleo and Cosmopolitan were to change their content to suit the younger readers than they may lose readers and they would not be aimed at the 18 to 35 year old market any longer. It seems, with these two magazines in particular, they are mostly focused on topics such as sexual intercourse. Parents feel these magazines are not appropriate because of a perceived breach of moral standards. Cosmopolitans morals were questioned when a monthly issue was on sale in a Woolworths store. They received many complaints about a headline regarding a guide to a mind-blowing blow-job.  [53]  Cosmopolitan were forced to place stickers over this headline as it was inappropriate for the consumers in a supermarket. Many critics consider it inappropriate for young teenagers to be reading material such as that in Cosmopolitan and Cleo, and it is just as inappropriate for pre-teenagers to be reading Dolly or Girlfriend with the content they represent. Magazines have the potential to influence young minds about what is acceptable and unacceptable in society as well as altering their way of thinking about sexual intercourse and gender roles. There are other reasons why teenage magazines appeal to a young audience. Firstly, there are the striking colours, secondly, the famous boy or girl splashed across the cover page and thirdly, the desire to be cooler and mature for their age. These magazines reveal little about the value of academic achievement and intellectual challenges. It is fair to say that the brain is not the hot organ at the centre of the teenage magazine world. This lack of concern about formal education is reflected in Dolly and Girlfriend with less than 20 per cent  [54]  of articles focused on education and/or intelligence. Only Cosmopolitan and Cleo frequently publish articles about careers. However, of the articles published in each magazine, less than 5 per cent  [55]  of the articles are based on careers. The effects of these magazines Teenage magazines can affect teenagers in many ways, both positively and negatively. However because people tend to focus on the negatives it appears as though most of these effects are, in fact, negative. A study by the British Medical Association  [56]  has shown that: The media are a significant and pervasive influence in modern society, and provide information about gender roles, fashion and acceptable body image which may be particularly influential on those young children and adolescents who are heavily exposed to its content  [57]   And: Young women may compare themselves to extremely thin models à ¢Ã¢â€š ¬Ã‚ ¦ and perceive themselves as fat in comparison, rather than healthy and attractive  [58]   This sort of influence on an already insecure teenager could result in social and psychological problems. These include eating disorders such as anorexia nervosa and bulimia nervosa, anxiety problems, depression and low self-esteem in susceptible personalities. Such problems are not healthy for the individual and restrict their quality of life. These problems, especially anxiety and low self-esteem, may arise from viewing the cover of any teenage magazine. This visual imagery may cause teenagers to feel insecure about their own body image, out of touch with the latest trends and even confused. Positioned on the cover of Dolly  [59]  magazine, April 2005, is an image of singer, Jessica Simpson, who is thin, toned, tanned, blonde, beautiful and in public view is her tight stomach and ample bust. For any girl who is not one hundred per cent comfortable with her outward appearance that image can be disheartening and depressing. Those who do not recognise the name or face of the latest guys youd sell your best friend for  [60]  can feel as though they are not up with the latest gossip or workings of, so to speak, girl-world. Those who do not understand the headline Stuck in Bloat Town?  [61]  can become confused even before opening the magazine. All of these thoughts and feelings occur before the person has even open ed the magazine. Once the magazine is opened, however, the feelings may continue or cease, it all depends on what part of the magazine the reader focuses on. The advertisements tend to send a completely different message than the articles they are placed next to and results in vulnerable teenage girls feeling uncertain about what message the magazine is trying to send. This mainly occurs when an article about healthy body image is placed next to image displaying a perceivably flawless, thin model.  [62]   Another impact on teenagers is caused by the fashions that models are seen wearing in magazines. These fashions influence the readers preferences. Teenagers will believe that if they wear that brand of clothing and that style of clothing they will look better and impress. This is not always the case, the clothes in magazines are often suggestive and send the wrong message. It could be interpreted that shes asking for trouble and a rebel when she is only following trends being fed by the magazines. Males can also be affected by these magazines, as well as females.

Medicinal Uses of Rainforest Plants It is estimated that nearly half of the world's estimated 10 million species of plants, animals, and micro-organisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation. Rainforest plants are complex chemical storehouses that contain many undiscovered compounds which are a vital part for the growth and development of the world. Therefore, we can only gain access and knowledge to these materials if we study and conserve the species that contain them. Rainforests currently provide sources for one-fourth of today's medicines, and 70 percent of the plants found have anti-cancer properties. However, they are only found in the rainforest. The rainforest and its immense undiscovered biodiversity holds the key to unlocking tomorrow's cures for today's devastating diseases. In 1983, there were no US pharmaceutical manufacturers involved in research programs to discover new drugs or cures from plants. However, today over 100 pharmaceutical companies and several branches of the US government, including Abbott, Merck, Bristol-Meyers, Squibb and the National Cancer Institute are actively engaged in plant-based research projects for possible drugs and cures for viruses, infections, cancer, and AIDS. However, I am presenting the preservation of the world=s rainforests by showing how much more valuable plants are standing rather than cut down. Indeed, it is a race against a clock whose every tick means another acre of charred forest. Yet, in a competitive market, whoever presents new evidence in chemical bioprospecting will secure health and a piece of scientific immortality.

No Zero Policy Essay

In most schools in many states, teachers and parents consider a grade of zero acceptable for incomplete homework. It is common for teachers to give zeros for late or slacked off assignments. Unfortunately, few teachers or parents question the usefulness of the consequence, and students continue to reap the consequences without benefit. Giving zeros as an punished measurement produces failure rather than performance. Administrators conjure up the fact that raising questions about grading procedures could induce powerful emotional responses from all the teachers. Even when school policies exist, teachers often deviate from the prescribed standard to reflect the teacher’s personal preferences for evaluating students. Grading policies usually develop from teachers’ personal school experiences without questioning or considering the validity of the process. Most teachers agree that grades are a measurement of learning and should reflect the effort of the student rather than the knowledge. However, many grading policies promise zeros for things like not doing homework, having incomplete or late assignments, being tardy, coming to class without books, chewing gum, or failing to follow through with any other required classroom rules. Unfortunately, many teachers combine behavior issues with a students’ academic measurement. Giving zeros for behavior issues is an inaccurate reflection of the student’s academic performance. Academic measurement should only measure learning. A zero is a mathematically imbalanced measurement as the normal grading scale for most school. Conant using the unbalanced tipped scale for certain performance classes. Letter grades usually have a ten point range or less. For instance, A would be 90-100, B is 80-89, C is 70-79, D is 60-69. Using this method, an evaluation for an â€Å"F† should be F as 50-59. It is not required for the â€Å"F† to carry 59 points (0-59) while all other grades carry 10 points. An â€Å"A† averaged with an â€Å"F† should make a â€Å"C.† However, if the â€Å"A† is 100 and the â€Å"F† is 0, averaged they equal a 50 which is still an â€Å"F†. Teachers usually use zeros to motivate students to do better. However, zeros kill motivation. Two zeros, whether just or unjust, can destroy a good average. Zeros produce a sense of hopelessness and certain failure. Many students fail courses due to a lack of organizational abilities rather than defiance. When teachers give zeros for homework assigned for extra credit rather than for the actual learning process, they are using grades as a behavior punishment. Recording a failing grade for assignments not intended for the means of simple knowledge is not reasonable. Assigning zeros for homework issues is especially common for students with organizational issues and dysfunctional homes that lack parental support. The grade of a zero does not benefit the motivation of a child’s education. Students through laziness take zeros as an easy way out of doing the assignment. Students often avoid assignments like research papers, essays, and reports by taking a zero instead of doing the work. The student barely passes to the next grade without having gained these vital learning experiences. Students with organizational problems do not increase performance skills through the automatic zero. Neither does the automatic zero help students who do not understand the assignment gain the knowledge intended. In fact, the automatic zero threatens failure. Teachers need to use logical consequences rather than a full blown zero when work is not completed. There are several possible alternatives to giving a zero. The school can include tardiness and other behavior issues in its own discipline policy rather than in the grading system. If the teacher must give a failing grade, give a grade no more than ten points lower than the last passing grade to make the measurement equitable. The teacher can have a homework detention hall after school to help those who struggle with completing assignments. The student receives a grade of incomplete until the student completes major assignments such as research papers, essays, and reports. The final average for the term is recorded only when the assignments are all received and graded. The student cannot earn credit for the course until these valuable assignments are completed and turned in. A minimal passing grade would be appropriate for extremely late assignments. For many years teachers have followed grading procedures learned from their teachers without evaluating their effectiveness or appropriateness. Grades should measure academic learning not the slacking effort of the student, for they may have their reasons. Receiving a zero for not putting your name on a paper or failing to do homework does not reflect a student’s lack of knowledge. Zeros promote failure rather than the student gaining more knowledge. Three 100’s averaged with one zero gives a score of 75. The zero forces failure and is not an evenhanded measurement of learning. Anything that is inequitable is unjust. If it is unjust, it is unethical. Therefore, giving zeros as an academic measurement is not proper to the safe learning environment of High Schools.

Phrases With Mangiare There are lots of great words and phrases with the word â€Å"mangiare† as a base, and as you go through them, try directly translating them from Italian to English as it makes them easier to remember. For example, â€Å"mangianastri,† which is â€Å"cassette player,†Ã‚  directly relates to â€Å"eat tape.†Ã‚  Italian compound nouns (nomi composti) with a form of mangiare include the following: fare da mangiare per: to cook forfinire di mangiare, finire tutto il pasto: to eat upil mangiafuoco: blusterer, braggart, swashbuckler, fire-eateril mangiamoccoli: hypocritically self-righteous person (popular term)il mangiapagnotte: someone who receives a public salary working with little effortil mangiapane a tradimento: scrounger, freeloaderil mangiapreti: a person who does not believe in the power of those religiously ordainedmangiare a saziet: to eat your fillmangiare bene: to eat wellmangiare come un maiale: to eat like a pigmangiare da cani: to eat badlymangiare fuori: to dine outmangiare la polvere: to bite the dustmangiarsi le mani: to kick oneselfmangiarsi le parole: to mumblela mangiatoia: manger, troughla mangiatrice di uomini: maneateril mangiatutto: big eater (also a kind of green beans, also known as â€Å"taccole† or â€Å"fagioli mangiatutto†) The verb mangiare is also the basis for the character name Mangiafuoco (Fire-Eater), the fictional wealthy director of the Great Marionette Theatre in The Adventures of Pinocchio.

In Italy, given the geopolitical background of its former city-states, the expressed animosity can be especially pronounced (and creative!). In Italian, there are  terms used to refer to individuals from other regions- admittedly pejorative given the context- that include the verb mangiare. Unfortunately, poking fun (or scorn) on anyone on account of their dietary habits or economic status  is not uncommon.

Ethics in the Workplace - Research Paper Example They also reported that the mine operators were notified by about 204 violations by the Mine Safety and Health Administration (Cooper & Urbina, 2010). The above report clearly shows that both the mine operators and the authorities were aware of the problems and still took no serious actions to rectify it. In other words, the lives of the mine workers were given least value by the authorities and the Upper Big Branch Mine operators. Mine works are considered to be one of the most dangerous works in the world because of the complexities of conducting underground operations. Bob Drogin and Nicole Santa Cruz have written on Los Angeles Times dated: 06 Apr 2010 that the Massey Energy Co., the mine owner...Officials said they didn't yet know the cause of the accident. They also reported that the federal inspectors who have inspected the company earlier found a lot of violations and have fined the company more than $382,000 for repeated serious violations (Drogin& Cruz, 2010). The argument of the company management that they don’t know the reason of accident itself shows that how less seriously they are addressing such a serious accident. They are deliberately trying to hide the fact that the company was caught and fined on many occasions for safety violations. They never learned lessons from their earlier mistakes. Both the company and the authorities are equally responsible for this accident. Loopholes in the governmental rules and regulations on mine operations were also contributed heavily to the Upper Big Branch Mine accident. Authorities even though enforced some fines, never tried to take any strong actions against the company. The authorities could have asked the company to close down their operations till all the  safety measures were in place. They failed to do so and satisfied with some routine inspections and fines. The company, on the other hand, was aware that the authorities may not implement any strong actions against them and continued playing with the human lives. In short, both the management of the Upper Big Branch Mine and the authorities like The Mine Safety and Health administration are equally responsible for the above accident.

Unit 2 Discussion art and Humanities Research Paper

Unit 2 Discussion art and Humanities - Research Paper Example According to the stylistic features seen in the portrait, it can be assumed that Andy Warhol did not show some seriousness in his work. This was so because many artists perceived designing of a self portrait to be very difficult for it involved a lot of research. Though this particular portrait is considered to be one of the most famous portraits in the world, it still does not meet the viewers’ expectations (Frei and George, 202). The portrait in this case does not earn fame because of the stylistic features used but being the first self portrait to be designed. Actually, no one still understands the main purpose of the portrait as it does not display the real Warhol. The viewers of this portrait are still expecting more insight and depth as they claim that there is nothing displayed but a whitish brown sketch that is behind sunken eyes (Fieldman and Jorg, 193). This shows that the color background of the portrait was not also well set as it tend to resemble or match that of the main portrait hence making it very difficult to see the portrait clearly. Some hidden parts of the portrait such as the eyes appear to be dark hindering clear view. From the features seen in this portrait, it can be concluded that the portrait is one of the famous self portraits that from which many artists drew their experience from. This portrait only brought some idea in the artistic industry as it showed that there is a possibility in designing a self portrait. The designing of portrait though took decades; it is considered a sketch work that only a partial image of the artist. This is also considered to have been so because Warhol who was the designer of this portrait was only advised to do so by a friend after designing many portraits and art works in the art industry.
