Break even

Breakeven is the point at which the company is not generating either profits or losses. This is the point at which the company is generating just the level of revenue which compensates for both the variable costs and the fixed costs. Variable costs fluctuate with the level of patients arriving for the scans. The greater the number of incoming patients for MRI scans, the greater the variable costs. However the fixed costs, which involve the lease payments, which are periodic, will not vary regardless of the number of patients coming in for the scan.Therefore, while greater number of patients means greater variable costs, it also means that there will be greater scope for the company to cover the fixed costs. That is of course given the fact that the price is higher than per unit variable cost. That is the case under the present scenario. The price that each customer pays for an MRI scan is $2100 while the cost that the company has to incur for each scan is $1200. The difference betwee n the price and the variable cost goes towards covering the fixed costs. That is why the breakeven equation stands as it does.As mentioned before, breakeven is the point at which there are neither profits nor loses for the company. As a result profit at this point can be considered as zero. The level of sales at which profit is zero means that under the present circumstances, the number of MRI scans that the hospital has performed cover for not only the variable costs but fixed costs as well. In the present scenario the payment that the hospital receives in return for performing the MRI scan is $2100 which is much higher than the cost of performing that scan which is $1200. Therefore, the company will have no problem in covering for the variable costs.What the hospital has to worry about is covering the fixed cost. Therefore the objective here is to determine the number of patients at which the difference between total revenue and total variable costs equals the fixed costs. The equ ation generates the 100 patients that R Squared must scan each month to cover not only the variable costs of performing each scan but also the fixed costs of operating the MRI scan equipment. 100 patients indicate the minimum number of patients that R Squared must scan each month in order to be able to stay in business, i.e. get back both the variable cost and the fixed costs. However General Hospital is ensuring 125 patients each month. This is very good for R Squared because at that number of patients, the hospital will be generating a level of profit that is higher than the $10000 calculated in question 2. Therefore R Squared will accept this contract. Question 4 If R Squared does not accept this contract it could reach an agreement with General Hospital whereby part of the costs for operating the equipment could be borne by General Hospital.This will reduce both the variables costs and the fixed costs for R Squared. In that scenario the management of the company could afford to accommodate a lower number of patients as it has to cover for a lower level of costs. Of course since 125 patients on a monthly basis means nearly $22500 of profits, there is no reason for the management not to accept this contract. However the management could be targeting a higher level of profits from its MRI division. In that case, a strategic alliance in the form of cost sharing as mentioned before could help both parties reach an agreement.

Social Influence on Bullying in Schools

Social Influence on Bullying in Schools Introduction There is no globally agreed definition of bullying. Tattum (1993) defines bullying as, â€Å"the desire to hurt or put someone under pressure†.Advertising We will write a custom research paper sample on Social Influence on Bullying in Schools specifically for you for only $16.05 $11/page Learn More Bullying is the most malicious and malevolent form of deviant behavior widely practiced in schools and yet it has received only scant attention from national and local authorities (Tattum Lane, 1998). The vast cases of bullying take place in on school premises and most students in playgrounds are affected (Whitney and Smith, 1993). It is therefore vital to understand better the interactions and activities of students in schools in order to place specific behaviors like bullying into context. Over the past two decades, there has been a growing awareness of the extent of bullying in schools. Research in this area, inspired by the work of Olweus in Scandinavia, has done much to focus attention on characteristics of bullies and victims. A good deal of research on bullying in schools has developed around a concern with personality and other individual attributes of bullies and the victims. This is obviously vital but can sometimes obscure the situational and social influences on bullying behaviors (Blatchford, 1993). The fact is that most bullying in schools goes undetected for the very good reason that the victims are too terrified to report their suffering for fear of reprisals which can often be brutal (Pepler, Rigby, Smith, 2004). The characteristics which typify a student who is being regularly bullied are known to us. Once a student has fallen foul of the bullying menace, and demonstrates that he will not ‘split’, the bullying becomes more intense and the ensuing terror increases (Pepler, Rigby, Smith, 2004).Advertising Looking for research paper on education?

Get you r first paper with 15% OFF Learn More Social Influences of Bullying Behaviors Much has been written about the reciprocal interplay among the individual, family, peer group, school, community and cultural influences on human behavior (Espelage Swearer, 2011). Social dominance theory, Demographics, School and Family characteristics are very strong factors which affects the behavior of bullying in schools. Social Dominance Theory A social biological or evolutionary perspective offers a view of peer harassment through the social dominance theory (Sanders Phye, 2004). The theory helps us to understand that the behavior of bullying has to do with the bully-victim interaction with the individual who bullies (Sanders Phye, 2004). According to Pellegrini Long (2002), social dominance theory is, â€Å"harassing or bullying behavior which occurs to force someone into a position of submission, which can especially be seen in boys during the transition from primary to second ary schools as they figure out the new social hierarchy†. According to this theory the evidently stronger students in any school will tend to dominate over the weaker ones (Sanders Phye, 2004). This is the core reason why physical bullying has to do with the size and strength of an individual subjecting his colleagues to bullying (Carney Merrell, 2001). The theory helps us to understand why the stronger members of the school population are likely to â€Å"rule† over the weaker members of the school as described in the social hierarchy concept in the theory (Sanders Phye, 2004). For example, within-groups aggression can take place in the context of the school as a whole, a grade within the school, a particular classroom within a grade, or a friendship group (Sanders Phye, 2004). One clear method of establishing social hierarchies and status within groups is through the use of aggression (Sanders Phye, 2004).Advertising We will write a custom research paper s ample on Social Influence on Bullying in Schools specifically for you for only $16.05 $11/page Learn More Perhaps aggressive students are admired by peers because rather that threatening group cohesion they actually promote a clear hierarchical organization within the groups (Sanders Phye, 2004). This theoretical approach sheds some light on why the aggressive victim group of students is so disliked and rejected by classmates (Sanders Phye, 2004). These are the students who have the capacity to destabilize the hierarchy, thus making individual group members feel uncomfortable (Sanders Phye, 2004). Aggressive students have been found to attack both weaker and stronger individuals, whereas â€Å"pure† bullies most frequently bully weaker students (Sanders Phye, 2004). Social dominance theory provides rationale for occurrence of peer harassment across the lifespan (Sanders Phye, 2004). However, an evolutionary/developmental approach to this theory can expl ain why using peer harassment as a means to establish social hierarchies might be especially prevalent and important during adolescence (Sanders Phye, 2004). Demographics and Bullying Demographic factors such as family, self-esteem, peers, ethnicity and socio-economic status also have an impact on the bullying behavior in schools. Students who portray low self-esteem are usually at great risk of being bullied and being forced to submission to the aggressive individuals (Hinduja Patchin, 2010).Advertising Looking for research paper on education? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, it must be pointed out that, self-esteem is not the key factor that makes a student to be victimized. There is simply a correlation between low self esteem and being a bullied. The way children are taken care of by their parents is also a contributing factor to bullying behaviors in schools. According to Wang, et al. (2009), â€Å"higher parental involvement led to children being less involved in all forms of bullying†. Wang, et al also notes that, parents who have over protective behaviors for their children and also over involved in their children’s affairs predisposes their children to bullying victimization at school (Juvomen Graham, 2001). Friendship also affects bullying behaviors in schools. A student with more friends is likely to be less physically, verbally and relationally bullied. On the other hand, a student with few friends is more likely to be physically, verbally and relationally bullied (Wang et al., 2009). Socio-economic status is also a fac tor which leads to bullying behaviors in schools. A survey conducted by National Association of Health Education Centers in 2004 found that, students from low socio-economic status families in Black/Hispanic schools were more likely to be bullies. There is high correlation between being a bullying victim and the socio-economic status of the student’s family. Due et al. (2009) asserts that, â€Å"Adolescents who attend schools with larger economic inequality among students, and adolescents who live in countries with larger economic inequality, are at elevated risk of being victims of bullying† (p. 907). School and Family Characteristics Associated With Bullying Because school culture varies by individual schools and school climate is created by staff and student attitudes, it logically follows that school and family characteristics are linked to bullying and victimization (Espelage Swearer, 2011). A study conducted by Kasen and Cohen helps us to understand bullying at the school level (Kasen Cohen, 1990). Through their study this authors reveals to us the impact of school climate on the intersection of personality and bullying. They concluded that students who are bullied perceive less social support in their peers and students who are bullying perceive less social support from parents and teachers (Espelage Swearer, 2011). Conclusion It is imperative that the role of social support is an important contextual factor in bullying prevention and intervention programming (Espelage Swearer, 2011). The research base regarding bullying has grown exponentially since Dan Olweus’ pioneering intervention research in the late 19th Century. However, the field is still in a relatively early phase of development (Espelage Swearer, 2011). Several types of measures have been developed to assist school professionals in monitoring the progress of bullying interventions (Espelage Swearer, 2011). It is recommended that practitioners and educators work toge ther to identify a set of measures for determining the most effective school based bully based prevention programs.

But in fact, obesity IS seen as the bane of existence for women around the world in developed countries as they are De chivied by the beauty industry resulting in eating disorders in order to measure up to an unrealistic and unhealthy weight. As Shower author of beauty Standards states: Eating disorders occur in societies where food is abundant and the body ideal is thin. They do not occur where food is scarce and people have to worry about where e their next meal is coming from. For example, there is a lower incidence of eating disorder errs among women living in monoester, non industrialized nations and among certain et hon. minorities in the United States. Immigrants to Western countries are more like Ely to develop eating disorders than those who remain in their country of origin. As economic changes occur in monoester societies, the incidence of eating disorders is in creasing. They are becoming common clinical problems in young women in high income e Asian societies such as Japan, Hong Kong, Singapore, Taiwan, and the Republic of K area . Kim 3 They have also appeared in major cities in allowance Asian countries such as China, Malaysia, the Philippines, and Indonesia . They have even been identified in u unexpected locations such as India and Africa. In addition, ideal standards of beauty in any culture Re communicated and passed down to new generations in various ways, including personal example, through story ling, poetry, fiction, art, and, in modern times, the mass media (Sheerer). It is through the e fads of beauty that women aspire to follow, even though at one point todays ideals of beauty y would have been scandalous. Likewise, the worlds culture of the human body is redesigning, r escaping, and refashioning ourselves to satisfy or meet the standard s of our social means d urine different time periods Cowboy Culture). Every culture has their own unique standards of BEA duty dependent of what is popular or mainstream at the time. During the Renaissance period, the e ideal women had red lips and cheeks, white skin, blond hair, dark eyebrows, a long slender neck k, firm, round reacts with pink nipples, small feet, and a slim waist (Sheerer). During the 16th century in Europe, the emphasis on pale skin indicated delicacy and purity, a female virtue u Compared to darker or more vivid tones, which were regarded as masculine (Sheerer). Alls o, it was for several centuries that China emphasized the importance and beauty in small f et as foot binding was the key to a womans beauty. For Chinese women who did not have small feet during the Five Dynasties Period was suicide because foot binding was essentially Amanda Tory step and duty in order to gain a husband can provide for them. Equally important, the West erne standard of beauty is becoming the global standard of beauty. Some critics argue that by accepting a Westernizes global standard of beauty, ethnic groups around the world are to sing aside important elements of their culture. Others assert that standards of beauty AR e overcharging and Kim 4 cannot be defined strictly by history. Celebration Concepts of Beauty). M rover, throughout the globe, thinness is the new fad that defines beauty, and whom en not just in the United States, develop serious eating disorders like bulimia, anorexia nervous , and more. About vive to ten million Americans are affected by eating disorders, and among too SE millions, it is estimated that 5 to 15% of people are diagnosed (Smiling). Regarding eating d crosiers, the problem begins when Satisfaction changes into a distorted and extremely negative image and this excessive preoccupation with the idea that some part of a persons p hysterical appearance is deformed or ugly is the definition of body dystrophy disorder which is IM packed by the media and the members of the community (Body Dystrophy Disorder). Co untiringly, social and economic status has become based on beauty. The body culture reflect[ s], therefore, the social ten sions, culture, and politics of the period (Body Culture). Beauty is n to found in the body but expressed through the body. The cultivation of the human body all owed people to create a sense of sulfanilamide and personal agency (Body Culture). The concept of beauty is a global issue concerning the young women of today because the modern world is too focused on perfection, and in certain cultures, to pro cure it is to go through series Of painful procedures. In fact, in a world where beauty comes first, people will whose to cut, reshape, and fix their face and body to fit the standards of.. Hat is seen in magazines, in movies, and on television (Mimes). Another problem facing whom en is the restriction beauty proposes to women, and in countries like the United States, England, China, and Korea, it incarcerates women and prevent women from being free. More over, society puts restrictions on women by valuing beauty above other attributes. Certain tattoo so, beauty marks, hairstyles, and body shape roughly indicates peoples position in a commun ity Also, the mass Kim 5 media pressures women fainting to look perfect by promoting cosmetic us Gerry. The picture perfect models that graces the cover Of magazines are promoted in a twisted kind of beauty as it is nearly impossible for humans to be perfect because we are not. Instead of appreciating and loving their looks, Women undergo sometimes painful processes with the AI m of being considered beautiful, and thus desirable (Magenta). Programs like Photos p alter, distort, and fix the natural body in magazines, movies, etc. The issue rampant around the e world, especially in more developed countries like the United States and the Great Britain, and in these countries omen are most susceptible to the dangers of the media and their standards of beauty. Mass communication and media has made international standards of beauty convey rage; the Western features are slowly but surely dominating and changing the beauty standards of the world. This is an issue because other groups and nations lose their own identity and cult re as they try to fit in with what is mainstream. The loss and fading of a cultures identity is fourth re a restriction on women. Not all women are of the same background, culture, or even have the e same physical features yet many women from the African American and Asian cultures try t change their own identity to fit the Western image. By engaging in beauty practices women try yet live up to the beauty images communicated to them via their male partners, advertising, FAA scion designers, (porn) movies, and others, and by doing so, women are restricted (Charisma) Pressures not only from family and peers but also the media to diet can fourth re distort body image, which lead to Abnormal eating behaviors and increase the risk of eating disorders. Having a healthy body image means you are accepting and appear dative of your body and realistic about your body size. The most common body image problems I include dissatisfaction with your body and distortion, which is the inability to see your self as you really Kim 6 are. Body image problems can affect eating behavior and increase the risk of eating disorders (Smi ling). In countries like the Unites States, Europe, and Asia, the ideals and s tankards of beauty are the sources of all evil as women are bound to the beauty industry, and in some cue Trees like Bangkok where women will go through dangerous cosmetic prop dress for the sake of beauty, the chains and the grip the body culture has on women become dig term and tighter (Bangkok Deadly Obsession with Beauty). Sheila Jeffrey, a scholar, author, p lattice activist, has similar opinions in which she has a vision of a world without harmful BEA duty practices which seems to be a utopian one in a world organized into along capitalist line sees (Charisma). Along with pressures to conform to Western beauty standards, ideals of thin news in Asian American women are influenced in anorexic or bulimic behaviors (Low). Ho waver, the stereotypical standpoint of eating disorders being a white womans issue ha s gone beyond just white women. Thinness, in todays society, is the ultimate goal women must achieve in order to be considered beautiful or even just fit in with the main crowd. Thinness is not just a headache in Caucasians, but also in other cultures such as African Americans, Latino, Asians, and more. The ideal of thinness is the supreme restriction on women in these e cultures as being thin is the first big step to being close to the ideal. Furthermore, among the Mended people of the Sierra Leone in Africa, women aspire to be as beautiful as Tangoing, a merman id in Mended mythology, who is regarded as perfection, and the mythological mermaid who chi is considered to be the ideal woman, in this culture, has long, thick, strong hair, an imports NT focus of appearance for Mended women, as well as some other feature-?eyes, head, BRB seats, hands, legs, or buttocks (Sheerer). Furthermore, African American women are affected by t he problem Of beauty as they allow the Western features to dominate and dictate what is De med beautiful. It is Kim 7 wrong that African women have allowed the West to dictate to us what a BEA dutiful woman should look like because this kind of thing makes African women feel inferior to white women (Adjoin). The West promotes long, straight hair and African American women hide their curly hair by weaving or getting a straight perm. Beauty plays an important role in classifying people to their respective social hierarchy. Beauty standards can have a strong impact on social attitudes and interpret Anal relations. Studies have shown that people tend to hold certain attitudes toward those t hey find attractive (Sheerer). Thus, practices related to the cultivation of the human body have served as means to symbolically reinforce social distinctions (Body Culture). Beauty comes Han d in hand with ones social hierarchy as beauty determine s her social status and judgment. To people who find those attractive, more positive and charming comments are rendered rather t Han a condescending judgment. In other words, in todays world, the beautiful people of all sexes have a greater choice of sexual partners, and more chances of raising their status by fair me anus or foul (Martin). Continuing, outward appearance directly correlates to peoples such sees and freedom in society. In fact, as stated by Smiling, an author of Nutrition and Eating Dish orders: In North America, where young women are particularly concerned with body I age, being thin is associated with beauty, success, intelligence, and vitality. No Am Rican girl wants to be plump. Young women find themselves in a world where they are expected to be independent, have a prestigious job, maintain a successful love relationship p, bear and nurture children, manage a household, and stay in fashion. These pressures may make them feel they are unable to control all aspects of their life, so they turn to of do intake and body weight as an area in which they can exercise control. These are Nat rural choices, Kim 8 because society tells us that being thin brings success (Smiling). Additionally, the borrowing of western culture and the fashion and entertain meet industries, which set the pace and trend for almost every aspect Of our lives h eave not helped issues with the stiff competition to appear perfect (Cheating Nature With Coos emetic Surgery! ). In the film King Kong, King Kong mistakes the main character for another whom an with blonde hair and fair skin, this shows how only people with characteristics like the maim n character is beautiful. Sherry McCarthy, who writes in Blonde Is Beautiful Mystique on USA Today, admits that she was disturbed by its gender message: that foreordained blond news is the essence of female beauty, so powerful an aphrodisiac that it can tame a savage beast. The beauty industry is dramatic in that it emphasizes and alters possible beau Toto impossible. Advertisers want people to think that the beauty promoted by the e media is obtainable by using their products. This is a trap that the media has created s o that people will spend more and more. It is a way for advertisers to make money (Negative B DOD Image). Evidence as follows from Negative Body Image: The Beauty Industry you see them every. Where-?perfect, beautiful women an d men. Anywhere you look-?magazines, television, movies, even video games-?you c ant get away from seeing females and males who either look like or actually are fish on models, staring you down and making you feel less than perfect. But the truth is, these e perfect models look this way for many reasons. First of all, they are usually wearing h eave makeup (even to achieve the natural much that you probably would dont even recognize models if you saw them on the street without their makeup. Special I camera angles and lighting add to the illusion of perfection. Most pictures of women I n fashion Kim 9 Gaines are airbrushed or altered by a computer. This means that after the photo is taken, professionals use special tools to correct any imperfections that show up in the photo and might make the model look less than ideal , and According to a r search study on social issues, todays media ideal of thinness for females is achievable e by less than 5 percent of the female population. No wonder that a 1995 study found that after just three minutes of looking at a fashion magazine, 70 percent of women nit reviewed felt depressed and guilty. In 1 999, Anne Becker, director of research at the Harvard rd Eating Disorders Center, reported that when she surveyed teenage girls on the island d of Fiji in 1998, only thirtieth months after the medium of television first became via label on the island, 74 percent reported feeling too big or fat at least sometimes. Too SE who watched TV at least three nights per week were 50 percent more likely than to hers to see themselves as too fat, and 30 percent more likely to diet, even though they w arent overweight. Solutions in alleviating the problems caused by beauty include: promoting diva resist instead of focusing on Western features, helping women to have more confine dunce in the body, ND help change the impossible beauty the media promotes to standards that t are realistic. For example, by being open to and promoting the beauty of what other cultures a ND nations find beautiful, there will be more diversity. Allowing more diversity will help alleviate ate the restrictions as it will provide women with more to consider and appraise as b dutiful than just the hootenannies features. Women who do not fit the image of the Western CUL true, especially women from other ethnic groups, will be less restricted and free. Furthermore e, by promoting and helping others, especially women, to have confidence in their natural body an and its flaws will Kim 10 decrease the restrictions on women. Also making changes to the distorted IM ages the media brainwashes can help the future generations to grow up with more truth. Insist dad of promoting the deceitful pictures of Victoria Secret models or the ambiguous commercial s on television, the media should advertise the real body culture. The f act that many people have become obsessed with beauty either do not know w how it affects them negatively or are not doing anything to change this reality has become problematic.

It should include the sales goals, which should be specific and measurable. The goal bases on the nature of product and breaks it down into manageable parts. For example, sell 50 units to end-users in 30 days and sell 100 units to local independent retailers in six months. Through this, the management will be able to know the projection of profits they would be able to make at a certain time (Ellis, Fitchet, Higgins, Jack, Lim, Saren and Tadajewski 25-26). The company should ensure it has sales activities, which would help the management develop a plan that makes sales. The sales can be direct-to-consumer through a website or via craft shows. In addition, the sales may include activities like developing a sell sheet, to send to independent retail stores (McLeish 45). This will enable the company realize more sales with more strategic sale plans in place since the management will know what to undertake at different times of economic downturns. With the growth use of the social site in UAE, the marketers should consider marketing the product on the website. ... Inconveniences arise to its customers if the number of distribution channels is too few, while too many distribution channels may increase its operating cost. There should therefore be a retail store with easy access and more convenient to the consumer (Ulph 98). The company should seek to adopt e-commerce fully at the stage of webpage promotion of products and services. This increases the chances of online sales and marketing at large. Summit sportswear should also seek to franchise its distribution channels, not only to increase its incomes, but also to minimize its operating cost and unify its operation mode to enhance its brand identity. In coming up with the retail prices, the company should research its competitors' prices and manufacturer suggested prices to determine product pricing. Once the product has moved from the wholesale, the retailers should decide on what type of retail prices to set. They can determine price by using three pricing models: cost-based pricing, compet ition-based pricing or customer-based pricing. Cost-based pricing sets the retailer’s price based on product and operating costs. Competition-based pricing uses local competitors' prices to decide on retail charges. Customer-based pricing sets retail prices based on how much the products is in demand (Ellis, Fitchet, Higgins, Jack, Lim, Saren and Tadajewski 180). In determining retail prices and the willingness of the customers to buy, the managers should review the manufacturer suggested retail price as a starting point. This would give managers an idea of the value of the product from the manufacturer's perspective. The organization should set prices close to his competitors (Synder 98).

Serenity in My Bedroom at Past Midnight - Essay Example I selected Khaled Hosseini’s The Kite Runner. I longed to travel to another culture, time, and place. I wanted to know about Afghan beliefs and practices, as well as their food, music, literature, and clothing. Mom prepared my favorite chicken sandwich with generous chicken breast strips and low-fat mayonnaise. She always puts diced onions, several slices of pickled cucumber, and tomatoes and used toasted wheat bread. I sat on my comfortable reading chair with sufficient light for my reading session. I took a moderate bite size of my sandwich and tasted the spicy, salty, sour mixture of the mayonnaise, pickled cucumber, onions, and pepper. The chicken tasted moist and fresh, as well as the tomatoes and crisp tomato. The cold wind rushed in spurts from my window. I sipped hot green tea for every bite of my oven-baked sandwich. The warmth of my green tea relaxed me further. The feel and smell of a good book refreshed my spirit. I prepared to embark on a long and wonderful journe y to a faraway place. â€Å"Some Good Things are Too Good to be True† But sometimes, good things come to an abrupt end, which began when I forgot to lock my door. My eight-year old cousin visited us this afternoon. Or rather, his parents left him overnight. They wanted some precious â€Å"us† time, and now I understand why. ... His shirt reminded me of a tire that ran on mud with stones and twigs sticking out. My mind somehow disconnected from my physical body, as it felt the horror of a good night saying goodbye. I saw my reading self as an image breaking into pieces, and I heard the clattering of the pieces on tiled floors. Then, I went back to the real world. I heard him whining about our outdated PlayStation and asked when we would purchase a suitable Xbox for his recreation purposes. And I smelled something else that did not register immediately in my nostrils. He had some green puke matter on his collar. I sensed his sticky hand on my arm, while he said that I was not listening to him. I felt sick to my stomach, and soon my sandwich tasted like iron. Heat rose to my neck. I must have turned into an eggplant by then. My perfect night laid in ruins, as I listened to him chatter about his computer games. Rhetorical Analysis I created these two different impressions of the same time and place through usin g the tools of description, narration, and example and illustration. Narration refers to telling about events and characters. I used narration to describe myself as a character in my own story and to narrate the events of my story. The first paragraph showed that I enjoyed classical music and set aside time for recreational reading: â€Å"I played Wolfgang Amadeus Mozart’s Piano Sonata No.16 In C Major to set the mood for my planned late night reading last Friday.† This paragraph also included my mother, who prepared an amazing chicken sandwich, one of my favorite comfort foods ever.

The first reason why it would be important to use these project management techniques and processes in the Ashleigh Music Festival is because the project management team will be provided with the opportunity to take charge of the available resources so as to ensure that the team produces the highest quality deliverables that are on time and within the set budget (Bradford, Duncan & Tarcy 2000). This is much easier when project management techniques and processes are used to plan and execute a project (Cleland 1994). The second reason why it would be important to use project management techniques and processes in the Ashleigh Music Festival is to ensure that all set deadlines for the project are met and that all the necessary actions have a timeline at which they should be executed and a chieved (Burt, Dobler & Starling 2003). When project management techniques and processes are applied, deadlines for each action are given. This means that all the actions will have a timeline during which they should be carried out and completed successfully (Cleland & Gareis 2006). This increases the chances of the entire project succeeding as opposed to when there are no set deadlines. Defining the scope of the project is important because it will help the project to focus on what it is set to achieve, and nothing else. It will enable the project team to remain on course and focus their attention on only what the project is set to achieve. Producing a project plan will outline all the processes that need to be conducted and show how they shall be executed. The plan will act as a guide for all the actions that take place during the project’s life cycle. Getting the right team together is also one of the most important factors that will determine whether the project is succes sful or not. The project team is the heart of the project because it is responsible for planning for it and executing it. Creating a business case is necessary because it will provide a solution to the problems likely to be experienced in the project. Essentially, project management entails a number of processes and standard control systems that will ensure the success of projects like the Ashleigh Music

Lab report Essay A molecular diffusion experiment of acetone-air (redundant w/ last sentence. . concise)was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment, acetone was placed in a test tub 3mm OD, 2mm ID . . (is that correct? ) NMR tube? e and was allowed to diffuse into non-diffusing air that was passed over the test tube. The air that passed over the tube was from natural circulation in the room and no air was forced over the top of the test tube. The diffusion occurred over a period of approximately eight hours, with readings taken each hour. After analyzing the data collected from the performance of this experiment, tThe diffusion coefficient was calculated to be 0. 098 + 0. 02 cm2/s at T = ?. After completing our calculations, oOur results were then compared using the Chapman-Enskog equation as well as the Fuller, Schettler, and Giddings method. The diffusion coefficient calculated by the Chapman-Enskog was 0. 990 + 0. 001 cm2/s and the result of the Fuller, Schettler, and Giddings method was 0. 104 + . 002 cm2/s. The literature value found in Perry’s Chemical Engineer’s Handbook was 0. 125 + 0. 00 cm2/s. (at T = ?. . . or extrapolated from? ) The agreement of our method with the other methods available for calculating the diffusion coefficient was very good (how good is â€Å"very† good. .. significant discrepencies or not? ), and also agreed well with the literature value found. This led to a conclusion that this method of determining the diffusion coefficient of acetone into air can be aconsidered a reasonably reliable method. BACKGROUND Molecular diffusion is the transfer or movement of individual molecules through a fluid by random molecular movements (Geankoplis 412, year of publication). In the diffusion process, the molecules of interest flow from regions of high concentration to low concentration. Molecular diffusion can occur in both directions with the system. In the case of the diffusion tube experiment, however, acetone diffuses through non-diffusing air, which is passed over the top of the test tube containing the acetone. The air is allowed into the test tube, but does not diffuse into the acetone. Molecular diffusion of gases has been studied for many years. Molecular diffusion is a mass transport process Motivation for its study comes from the fact that chemical separation processes such as distillation, drying, ion exchange systems as well as many other processes depend on molecular diffusion (Kirk-Othmer Vol 8, p 149(check format)). EXPERIMENTAL METHODS For the performance of this experiment, a small test tube was filled approximately a third full of acetoneBe specific. . how small, starting height, diam, etc. This test tube was then vertically placed in a 10mL graduated cylinder which contained small beads. The purpose of the beads was to ensure that the test tube remained vertical. This assembly was then placed on a digital scale. The amount of air movement provided by the ventilation system was assumed to be adequate so as to ensure that the concentration of the acetone at the top of the tube was zero. An initial acetone level in the test tube was taken, as well as the mass of the assembly and the temperature of the area surrounding the assembly. After this initial data was taken, the area temperature and mass of the assembly were taken approximately every hour for the next eight hours. The final level of the acetone in the test tube was taken when the final temperature and mass reading were taken. DISCUSSION OF RESULTS From the data collected from the experiment, the diffusion coefficient was calculated using equation 6. 2-26 from Geankoplis: (Equation 1) As the z value was only recorded at the beginning and the end of the experiment, the intermediate values of z had to be calculated. The following equation was used for the calculation of the intermediate z values: (Equation 2) Thus, all values but DAB were known and could be plotted versus time to obtain a linear plot. By rearranging equation 1, it can be seen that the slope of this plot will be equal to 1/ DAB : (Equation 1. 1) The initial plot of data which includes all points is shown below in Figure 1. This plot contains all points and has an R2 value of 0. 9478. From this plot the molecular diffusivity coefficient was determined to be 0. 108 + 0. 022 cm2/s. Figure 1: First plot of data in Equation 1 The second point in the data (t=2700s) showed no diffusion occurred in the first 45 minutes, which seems unlikely (yes, good- sensitivity of balance, etc). If this point is taken as erroneous, the R2 value goes up to 0. 9639 (more important here will be the confidence interval on the slop. . . get that from Tools- Data Analyis-Regression menu in Excel or else in Polymath or TableCureve, etc) and the molecular diffusivity calculates out to be 0. 098 + 0. 021 cm2/s. The plot of the experimental data excluding the second point is presented below in Figure 2. Figure 2: Second plot of data in Equation 1. . forcing through zero point is good. . . looks to me like first FOUR points would give a lower Dab then the last 4. Problems with next 3 that lie below line? Anytihing suspicious happening here? To determine the time it takes for the system to reach steady state, the following equation can be used to calculate the fraction of steady state the system is at: (Equation 3) By plotting the value of ((NA)t/(NA)t=? ) versus time, the curve in Figure 3 was generated which demonstrates the systems approach to steady state. Wow, great! Cite source.  (still wonder about SST conditions of 1st 4 pts though. . . Figure 3: Fraction of steady state versus time From this plot, it could be said that the system achieves steady state in 115 minutes; however, there is strong evidence this may not be accurate. As mentioned earlier, the second point may be erroneous. This would change the path of the curve. In addition, data was not collected at a high enough frequency for this curve to be highly accurate at predicting the time to steady state. If in fact the second point is erroneous, the system could have come to steady state well before 115 minutes. This time of 115 minutes at best, could be the upper bound (or lower bound according to Whitaker’s criteria in his article (handout). . . not sure!! for the time it takes for the system to come to steady state. The scatter in the data can be attributed to various factors in the experiment. The scatter could be attributed to the changes in temperature, as the temperature did fluctuate slightly through the duration of the experiment – Good!. At what time did it stabilize?. The change in temperature would cause a change in the partial pressure of the acetone leading to further deviations. In addition, there was no measure of airflow past the tube. Changes in the airflow could also have contributed to the scatter as it could effect the concentration of the acetone at the top of the test tube (Good! ). The diffusion coefficient was also calculated using the Chapman Enskog equation, (Equation 4) and the Fuller, Schettler and Giddings method. (Equation 5) A literature value was also found for acetone at K(check Perrys), which was corrected to our experimental temperature using the correlation (Equation 6) The values obtained with these methods as well as those from the experimental data are presented in Table 2. Table 1: Values of molecular diffusivity coefficients found. ** ** A very good way to show this graphically in Excel would be to use a bar graph showing the values of Dab as height of a bar by method used, and error bars to easily demonstrate any overlap of uncertainty, discrepancy, etc. Example: The Chapman Enskog method is accurate within 8% and the Fuller Schettler and Giddings value has a lower accuracy than the Chapman Enskog (Geankoplis 425). The Chapman Enskog value is less than 1% different than the experimental value and the Fuller Schettler and Giddings value only about 6% different. From this analysis, it seems these equations predicted the experimental value very well. These calculated values are about 20% lower than the literature value. This variance may come from the inconsistent temperature in the room or from pressure fluctuations in the room caused perhaps by the starting and stopping of the HVAC systems. For the derivation of Equation 1, several assumptions are made. Beginning with the general equation (Geankoplis 6.  2-14): (Equation 7) One assumption was that because the case examined was a diffusing A (acetone) into non-diffusing B (air), the diffusion flux of air into the acetone (NB) was equal to zero. Another assumption made was that since the total pressure was low, the acetone gas diffusing into air was an ideal gas. This allowed for the term c to be replaced with its ideal gas equivalent, P/RT. Add itionally, the air passing over the test tube was assumed to contain no water vapor. An average air velocity that was uniform was passing over the acetone containing test tube was also assumed. There are non-idealities that exist in the molecular diffusion of acetone into air. Some of these non-idealities are corrected for in the journal from Lee and Wilke. Acetone displays surface tension effects which, instead of having a perfectly horizontal liquid surface, give the liquid acetone a slightly downward curved liquid level. Because of this curvature, the actual diffusion path length that the acetone travels is smaller than what the diffusion length would appear to be based on center liquid level or calculated liquid volume (Lee 2384). Along with a non ideal liquid surface, the air passing over the open end of the tube may cause some turbulence to exist in the top portion of the tube. With its existence, the turbulent area of the tube will cause a length to exist inside the tube where the concentration of acetone is zero. With the presence of this acetone vapor-free region, the diffusion length is again shorter than it would appear to be. To account for the non-idealities in the diffusion process, Lee and Wilke do not use the apparent diffusion path. Instead, they use an effective average diffusion path which they give by: (Equation 8) Where x is the effective average diffusion path, ? xs is the length of the curvature of the non-ideal liquid to account for the surface tension forces, ? xe is the length of the tube where the acetone vapor-free region exists due to turbulence that exists from the passage of the air, and ? x ­ is the sum of ? xs and ? xe (Lee 2384). When this is substituted back into the diffusion equation, it becomes the following: (Equation 9) Where Da is the apparent diffusion coefficient and D is the true diffusion coefficient based on the true diffusion path (Lee 2384). The way our experiment was setup, the driving force for the air across the test tube was natural air flow and did not employ forced air flow. Because of this, the length of the tube where the turbulence existed in the Lee and Wilke journal would most likely not have been present in our experiment. Also, the initial liquid acetone level selected in our experiment was such that the length of the curvature due to the surface tension forces on the acetone would have been negligible when compared to the apparent diffusion length of the tube. The initial height of the liquid in the tube for this experiment was chosen wisely. The reason for this is that with the initial level that was chosen, a sufficiently long diffusion path existed such that the non-idealities that were accounted for in the Lee and Wilke journal entry would have had a very insignificant impact on the results of our experiment. CONCLUSIONS AND RECOMMENDATIONS From the data collected an analyzed, it has been determined that the experimental procedure used here can determine the molecular diffusivity coefficient with some level of accuracy. For future experiments, some form of air flow regulation should be investigated. Something as simple as a room fan could be placed next to the scale to ensure a more constant air flow. Another increase in accuracy could be achieved by regulating the temperature with more consistency. If the experiment could be performed in a large insulated room, the temperature may not vary as much.
