Lab Protocols :: essays research papers

Lab Protocols Through trial and error my class and I have learned that screwing around and misbehaveing in lab not only results in multiple page papers, but can also be harmful, dangerous, and costly to our teacher and school. There are many rules or "protocols" that should be followed in a lab enviroment. In this situation there are ten basic rules that must be followed at all times while participating in lab experiments. These are here for our own safety and should be followed for this reason. The first rule is that everyone in the lab should wear eye protection. In a lab enviroment eye injury is very common. Eye protection greatly reduces this risk of injury. The second is no horseplay. Horseplay can cause injury to yourself others and can cause damage to the laboraty. The third rule is that you should only interact with your partner and the teacher. This will prevent distraction from your set experiment. The fourth rule is that you should not leave your experiment unattended whether you think it is dangerous or not. This rule is completely self explanatory for safety purposes. The fifth rule is to be extremely careful with equipment. Not only for money purposes but also for your own personal safety. The sixth rule is to not touch anything that the teacher or the lab specifically instructs you to. Because you don't need to. The seventh rule states that activities should only be done if they are specifically discussed in your lab. This is for safety purposes and for the liability of the school. The eighth rule is that you are not to contaminate chemicals by using equipment in more than one substance without washing it thoroughly. Doing this can cause explosion, fire, bodily harm, poisonous gasses, or possibly death. Also do not return chemicals to the original container after they have been used. The ninth rule is that you must read your lab handout thoroughly before experimenting in a lab environment. It is a good idea to ask any necessary pertinent questions prior to partaking in your lab. Follow directions exactly. This is to prevent possible harmful mistakes that may result in death, poisonous gasses, bodily harm , explosion , or fire. Last but not least the tenth rule is that before taking leave of the

Race and Gender Schemas Essay

A person’s gender schema affects how they treat all other people regardless of age, race, or social position; because we assume that everyone fits into one of two categories: male or female. There are other cultures that do not have a binary gender schema, and allow people to occupy a â€Å"third position† combining traits that Americans would see as male or female. It is unfortunate that gender schemas are so restrictive and create expectations and judgments about people’s authentic selves that can damage the psyche (Valian, 208). As a way to navigate the social world, gender schemas can be important, but like schemas for race and social class, they can reinforce hierarchies that restrict a large part of the population. Below, I will talk about my own gender schema, how I view the gender schema of my society, and how it could be changed to better As media becomes an ever more powerful force in shaping the world’s perception of itself, an individual’s struggle to maintain a unique identity and self-understanding apart from media influence becomes increasingly difficult. Damaging to the idea of the self are the racial, gendered, and class-based stereotypes (always artificial and frequently physically, fiscally, and emotionally unattainable), which are broadly perpetuated and, because of their persistence, are apparently not broadly questioned. The prevalence and power of gender (especially female) stereotypes in the media are addressed in this p My own gender schema has changed radically from when I was younger. I can remember asking my mother â€Å"is that a boy or a girl? about a person whom my mother identified as a woman, but who had a very square, angular face with large eyes. Later, I learned to incorporate larger scale features (curvy hips or breasts; large shoulder-to-waist ratio) into my schema. Although I was raised as a girl and have always looked female (if not always perfectly feminine), I don’t always â€Å"act like a girl† – I am somewhat aggressive when playing sports, I’m not shy about asking questions, and I’m sometimes stoic about my emotions. This reflects my gender schema for males: â€Å"typical men† are aggressive in sports, readily ask questions, and do not express emotions. By contrast, â€Å"typical females† in my gender schema are concerned with their appearance, are not aggressive on the playing field, tend to be shy if they ask questions, usually assume that they are not in a position of authority, and express their emotions freely. My schematic representation of male and female physical features has relaxed slightly since childhood; plenty of the women I was with in high school were more angular than curvy. Even though I grew up in a fairly enlightened part of the world, men and women still used nonconformity to gender stereotypes/schemas to insult each other across group lines (women insulting men for being too female-like; men insulting women for being too male-like). Also, I was more cautious of people who did not fit my gender schema, because these schemas predict behavioral and cognitive tendencies, however unreliably. Although our society has changed significantly even in the past 30 years, gender schemas themselves are still very restrictive. It may be the case that fathers have increased their contribution to childrearing time so little because the gender schema for males still dictates that a man spend the best hours of his day at his job (TenenbaumLeaper, 616). Women are expected to conform to people’s gender schemas by liking children and being caring, sympathetic people – all qualities of good mothers. However, it is never clear that every woman you meet wants to be, or is even capable of being, a mother. Many people still retain a gender schema that does not allow for women in positions of power in the workplace. The industrialized nations’ gender schemas â€Å"support a sexist society by propagating an ideology of an innate and entirely pervasive, sex determined social structure† (Devor, 147). This is as bad for men as it is for women. For every woman passed over for promotion at work because their boss’s gender schema classifies them as a â€Å"mothering type,† unsuited for the fast-paced world of their chosen industry, there is probably a man in a high-pressure job that would like to ask for paternity leave, but doesn’t want to be belittled by â€Å"the guys. From my perspective as a woman, and as someone who has felt pressure to conform to a feminine gender schema, it seems like women get a worse deal if everyone uses the male/female gender schema in which typically-feminine behavior includes letting other people have their way, assuming you are not in a position of authority, and paying more attention to your appearance than your skill set. For gender schemas to change in society at large, gender schemas must change for children. The best way to do this is by exposing children to gender-atypical men and women in an accepting way, expanding children’s gender schemas and symbolically making it acceptable for men and women to be as â€Å"masculine† or â€Å"feminine† as they feel like. Another way to take the claws out of the American gender schema would be to legitimize between-gender roles, either by working towards acceptance of transgendered and transsexual populations or by studying the gender schemas of other cultures as a way to shift our own prejudices about what constitutes â€Å"maleness† and â€Å"femaleness. Shifting our gender schemas will allow people’s inherent strengths and weaknesses, rather than their adherence to stereotypes, to be the most important determinant of how we treat others. Heightened public awareness of both the existence of and potential damage caused by these stereotypes is essential if they are to be eliminated. Frequently, though, they are d ifficult to combat and even to identify because of the ways in which they are presented. Overwhelming amounts of time and energy are devoted to uplifting a small, specially selected portion of the population as models of physical perfection. These individuals are, predominantly, television and movie celebrities, fashion models, and sports figures. The glamorous ways in which these occupations are portrayed by the media are seemingly impossible to separate from the physical appearance of the people who hold them. The glamour that surrounds the media presentation of the lives and careers of these individuals extends, not surprisingly, to the clothes that they wear and the way that they look. In fact, so much attention is given to celebrity appearances that entire television programs are devoted to little else but visual exploitation of celebrity clothing and their tangible products of their latest fad workouts. The media presentation of the celebrity body has a single unifying thread, regardless of the specific job title of a given celebrity. Celebrity bodies are desired, both subjectively and objectively. The media, without question, shapes this public response. It can be argued (and has been, on many occasions) that, because the media portrays celebrities’ bodies as attractive, desirable, and â€Å"good,† they become national symbols of these characteristics. Conversely, bodies that do not meet this lofty goal frequently are, consciously or unconsciously, regarded as â€Å"bad† or ugly. Consider the most recent (and extremely popular) advertising tack used by Subway, the national fast food sandwich chain. Jared,† the protagonist of the recent slew of television commercials, allegedly lost hundreds of pounds while on a diet consisting primarily of the chain’s fare. Jared’s â€Å"before† pictures show him considerably larger than his current size, but they also show him alone, with no friends or family. In stark contrast, however, his â€Å"after† action shots consistently show him not only thinner, but also constantly in the presence of a beautiful woman, presumably his significant other. The advertising message is clear: fat=bad, ugly, unhappy and alone, thin=happy and with attractive partner. Through these commercials, Jared has assumed celebrity status, solely on the basis that his body has changed to approximate more closely the current standard of attractiveness. Sadly, though, there is a severe disconnect between the male and female body types lauded in the media and those of the public at large. A shockingly small minority of the population has the genetic dispensation to match with what the media purports to be attractive. For women, â€Å"desirable† physical characteristics (as they are portrayed in the media) include being thin, long-legged, slim-hipped, and large-breasted. The media-portrayed â€Å"desirable† physical characteristics for men include being muscular and possessing a full head of hair. Some characteristics are portrayed as desirable in both sexes, such as being tall, fit, athletic, young, and light-skinned. In the gap between what is implicitly beautiful in the eyes of the media and the physical reality of the popular majority flourishes a market of â€Å"self-improvement† products and services, ranging from hair dye and makeup to tanning salons, dieting, and plastic surgery. It seems as though nearly everyone, at some point in his or her life attempts to alter him- or herself in a physical way, in order to conform more closely to the marketed â€Å"norm† of attractiveness and desirability. Television, magazines, and newspapers are filled with advertisements promoting self-loathing, while offering â€Å"miracle,† body-altering â€Å"cures. † The body that does not conform to a sexy, sleek stereotype becomes a thing to be hated, improved upon, and generally tortured into submission. A portion of the damage caused by such a mentality is quantifiable, though observation of the huge profits accumulated yearly by various diet programs and plastic surgeons. The harm of this presentation of the human body can also be seen in our current societal epidemic of disordered eating, including anorexia, bulimia, over-exercising, excessive dieting, and over-anxiety over food. While the population subset living with and recovering from disordered eating is still predominately composed of women, the number of men with disordered and dangerous eating habits is on the rise. In addition to physical damage, intangible psychological harm results from body image problems to which the media contributes daily. When men and women are faced with the implication that their bodies, if they fail to conform to an impossibly stringent set of standards, are unattractive, unhealthy, and unlovable, they begin to lose confidence in themselves. The perception that a single, narrow range of body types is acceptable and healthy for men and women is not only in error, but contributes to widespread social discontent. Instead of celebrating the diversity and beauty of the human form, the media stifles our desire to feel comfortable with ourselves in an attempt to fool us into supporting a billion dollar self improvement market, from which the media garners tremendous financial benefits. In addition to (and perhaps more devastating than) the physical and emotional damage caused by the current media-driven obsession with achieving an arbitrary physical â€Å"perfection,† our society faces losing serious social perspective. As it is currently used in the media, the body is stripped of its uniqueness and forced into frustratingly narrow constraints: good/bad and attractive/unattractive. Little or no public attention is given to the countless other factors around which a person’s identity is structured: kindness, generosity, honesty, friendliness, work ethics, personal motivation, intelligence, and spirituality. By focusing too intensely on the physical, our society risks losing sight of the fuller sense of what people are, and what makes us truly beautiful. My LAP is going to talk about a personal experience that I have encountered with a family member. I have a brother who fits the schemas that we have spoke about in class. I feel that my brother has been dealing with identity issues for a long time since his childhood. How do you deal with being something that you don’t feel you are? Being in this class has me see that everything is not black and white. Schemas are just a stereo type and everyone that may be something does not always seem to be the case. Sometimes there are many reasons that people feel that they are a part of a schema it can be caught up in how people act. Many things on TV make people want to try things like being attracted to the same sex. But sometimes it can be what is going on in your environment. Sometimes I feel that I am a part of a schema I am one of the only black females at my job that is around wide variety of Reform Jews and to me I feel sometimes that I am not suppose to be there but I hold my head up high and keep my enthusiasm very high. So schemas are every day and it just does not have to be about sexuality.

Introduction Archers Organic Foods plc is a producer and distributor of organic foods. The company is looking to expand the business by acquiring a farm in the North of England. Don’t waste time! Our writers will create an original "Archers Organic Foods Essay Download Pdf" essay for you Create order This report analyses the financial viability of two farms by using a number of investment appraisal methods. The two farms differ in their initial investments, sales and costs. The freehold of option 1 farm will be acquired at the beginning of the project. The farm in option 2 will be taken on a 10-year lease with deposit and annual rent payments. The report makes a recommendation on the final selection of a farm by evaluating the results, strengths and weaknesses of four investment appraisal methods. The four investment appraisal methods used in this report are the Accounting Rate of Return (ARR), payback period, Net Present Value (NPV) and Internal Rate of Return (IRR). The results of the four investment appraisal methods may not be similar because of differences in their approaches and calculations. Hence, it is beneficial to use more than one investment appraisal method and understand the benefits and limitations of each method before making a final decision. II. Investment appraisal methods The four investment appraisal methods can be classified into two main categories. The ARR and payback period are non-discounting methods whereas the NPV and IRR are discounting methods. The ARR method measures the accounting profit rate by dividing the average income by the average investment (Hansen and Mowen, 2007, p. 568). The method is simple to use but has major limitations. It ignores the time value of money which is a major drawback in case of projects with long lives. Also, a benchmark rate is required for comparison. The payback period calculates the time required to recover initial investment from the operating cash flows of a project (Brigham and Houston, 2007, p. 373). Shorter payback period projects are preferred as they generate cash equal to initial investment in a shorter duration and this can be viewed as a proxy of risk. However, the payback period method ignores the time value of money (Kinney Raiborn, 2011, p. 655). It also ignores the cash flows after th e payback period which could result in a selection of a project that adds less value. The NPV method calculates the net value of a project by discounting the cash flows at a rate which reflects the risks of those cash flows. The discounting of the future cash flows is a major advantage of the NPV method over the non-discounting methods. This is very important for valuing the two alternatives as cash flows are spread over 10 years. The drawback of the NPV method is that it assumes constant gearing to maintain same cost of capital. This rarely happens as cash inflows over the period change the gearing. A company will have to issue debt regularly to maintain same gearing (Delaney, 2008, p. 37). This is difficult to do due to administrative issues and costs. It is also not easy to calculate cost of capital that is used for discounting cash flows (Howe, 1992, p. 34). Finally, the NPV method is not useful on its own when a company faces capital rationing. The profitability index may have to be used along with the NPV to evaluate investments in a capital rationing scenario. IRR method also discounts the future cash flows and gives the cost of capital at which the NPV would be zero. This gives an idea about the margin of safety that is available in terms of possible decline in the rate of return before it equals cost of capital. The limitation of the IRR method is that it can give two IRRs for same set of cash flows if the pattern of cash inflows and outflows reverses more than once during the life of a project (Brigham and Daves, 2009, p. 421). It also assumes that cash inflows during the life of a project will be reinvested at the IRR which may not be true as the firm may not have similar opportunities to invest in. The investment appraisal methods have their pros and cons and it is useful to use more than one method to get a better picture. III. Results of investment analysis The first option is the freehold acquisition of a farm at  £1,500,000. The calculations and results of the investment appraisal methods of option 1 are shown in appendix I. It is assumed that the farm will be sold for  £1,500,000 at the end of 10 years. It implies that the average investment over the period will be  £1,500,000. ARR = Average profit / Average investment =  £313,000 /  £1,500,000 = 20.83% The cumulative cash flows turn positive for the first time in year 6. Payback period = 5 + (245,000/360,000) = 5.68 years. The NPV of option 1 is  £739,000 and the IRR is 19.43%. The second option is to lease a farm for 10 years. A down payment of  £300,000 will be made at the beginning of the 10-year period. It is assumed that the down payment will be returned at the end of 10 years. The average investment will be  £300,000. The calculations and results of the investment appraisal methods of option 2 are shown in appendix II. ARR = Average profit / A verage investment =  £190,000 /  £300,000 = 63.33% The cash flows are adjusted to reflect the fact that annual rents will be paid in advance. The rent for year 1 will be paid at the beginning and hence shown in year 0. The rent for year 10 will be paid at the end of year 9 and hence  £150,000 cash is added back to the profits of year 10. The cumulative cash flows turn positive for the first time in year 5. Payback period = 4 + (160,000/190,000) = 4.84 years. The NPV of option 2 is  £623,000 and the IRR is 27.48%. IV. Analysis of results The ARR of option 1 is 20.83%. There is no benchmark available for comparison but it is significantly more than the cost of capital of 12% and hence the ARR method approves investment in option 1. The payback period is 5.68 years. Though the payback period is significantly lower than the 10-year life of the project, it does not meet the 5-year cut-off period set by the finance director. Hence, the investment in option 1 is not approved under the payback period method. The NPV of option 1 is very high and positive  £739,000. Purchase of the farm will increase the net value of the firm by  £739,000 over a period of 10 years and hence the investment is approved under the NPV method. Finally, the IRR of 19.43% is also higher than the cost of capital of 12% which again approves the purchase of firm. The ARR of option 2 is 63.33% which is substantially higher than the cost of capital of 12% and hence the ARR method approves investment in option 2. The payback period is 4.84 yea rs and it meets the 5-year cut-off period set by the finance director. The investment in option 2 is also approved under the payback period method. The NPV of option 2 is positive  £623,000. Option 2 is also approved under the NPV method. Finally, the IRR of 27.48% is also higher than the cost of capital of 12% which again approves the purchase of firm. Option 2 is preferred over option 1 by the ARR, payback period and IRR methods. However, the option 1 is preferred over option 2 by the NPV method because the NPV of option 1 is more than that of option 2. The difference results under the various investment appraisal methods are not unexpected. The ARR and payback period methods do not discount the future cash flows. This is a major drawback in this case as cash flows are spread over a long life of 10 years. Also, the cost of capital is a high 12% and not discounting the cash flows does not reflect the risk of the investment. In view of the above arguments, the results of the ARR and payback period methods should be viewed with caution. The NPV method favours option 1 as its NPV is  £116,000 higher than the NPV of option 2. However, option 1 uses higher initial investment and this is reflected in its IRR which is lower than that of option 2. The company should opt for option 1 as it adds the maximum net value to shareholders. However, if funding is restricted than option 1 should be preferred because it adds higher net value per unit of investment. The net value per unit investment is  £2.08 for option 2 as compared to  £0.49 for option 1. In addition to the above analysis, the investment decision should take into account few other but important points into consideration. Firstly, in the analysis of option 1, it was assumed that the farm will be sold for  £1,500,000 after 10 years. However, the prices of land and farms have increased in the recent years. The table below shows the sensitivity of the NPV to the changes in price of the farm. An annual farm price inflation of 6% over a 10-year period would substantially increase the NPV to  £1,121,000. This is a significant jump. Even if the annual farm price inflation is -2%, the NPV is still positive. On the other hand, the changes in farm prices would not have any impact on the NPV of option 2. The possible significant benefit from purchase of a farm should also be included in final decision making. Secondly, the evaluations are also sensitive to changes in cash flows. Projections are rarely met in practice (Arya et al., 1988, p. 499). It is difficult to accurately predict cash flows over a 10-year period because of a number of factors. The demand may change due to economic-wide changes. The costs of raw materials and labour may rise faster than anticipated. Adverse weather may also play havoc on the production. Hence, it is beneficial to do a sensitivity analysis of cash flows. It is assumed that the variable costs will move in direct proportion to the changes in revenues. The tables below show the sensitivity of the NPVs to changes in sales and variable costs. The above tables show that option 2 is more sensitive to the changes in sales and variable costs. At 80% of the base case sales and variables costs, the NPV of option 1 is significant positive but that of option 2 is marginally positive. The option 2 will turn into a negative NPV investment if actual cash flows are just less than 80% of the projected cash flows. Thirdly, the NPV is also sensitive to changes in the cost of capital. The tables below show the sensitivity of the NPVs of two options to changes in the cost of capital. Option 1 is more sensitive to changes in the cost of capital. The company should analyse the likely increases in the cost of capital over 10 years before making a final decision. In addition to the above-discussed points, the company should also analyse some of the key non-financial matters to ensure that the investment will yield positive results. It should analyse whether there would be local demand for organic foods in case of each option. Organic foods are sold at a premium to inorganic foods. The buying power of consumers is linked to the general overall economic conditions. The UK economy is passing through a tough phase with consumers concerned about government cuts in public expenditure. This may make it difficult for the company to sell its produce in the local region. The company should also consider the resources that would be involved in effective monitoring of the farm in the North as opposed to current operations in the South. Monitoring and control is important for success of an investment and long-distance could hamper it. V. Conclusions The results of four investment appraisal methods did not match and there is no unanimous choice. Option 2 is preferred on the basis of the ARR, payback period and IRR methods. Option 1 is the preferred option because of its higher NPV and the possibility to gain from an increase in farm prices. The NPVs of two options are also sensitive to a number of factors like cost of capital and changes in sales and variable costs. The NPV of option 2 is more sensitive to changes in cash flows whereas the NPV of option 1 is more sensitive to changes in the cost of capital. VI. Recommendations The recommended option is option 1 because of its higher NPV and also the potential to reap even higher benefits due to increase in value of farm over 10 years. If the project does not meet sales expectations, the company will have the option to sell the farm and exit early in option 1. On the other hand, the company will end up paying lease rent for 10 years in option 2. References Arya, A., Fellingham, J.C., and Glover, J.C., 1988.
