Anyone Can Write a Research Paper!

1. Begin early We as a whole do it. We hold up until the LAST day to begin a task, and after that, something turns out badly finally, and Oops! We get an awful review by Best Research Paper Writing Services in USA. Continuously begin your articles early. This is the thing that I suggest. Mainly since composing an examination paper requires more exertion than a customary paper may. 2. Read the Guidelines Ever removed a shirt from the dryer to discover it has contracted 10 sizes too little? This is on the grounds that the shirt likely wasnt intended to go in the dryer, and in the event that you had perused the tag, youd have spared yourself one entire piece of attire! Before you even START on composing an exploration paper, READ THE GUIDELINES. 3. Conceptualize look into paper themes Once in a while were appointed papers where we know precisely what we need to expound on before we begin. Compose an exposition on my most loved place to movement I know where I will pick! Be that as it may, there are presumably more occasions where we DONT know precisely what we need to expound on, and we may even experience an inability to write. Heres a case of a mind-delineate simply improved the situation Influential People! By composing whatever rung a bell and interfacing those musings, I could concoct many powerful individuals to expound on — I could think of EVEN MORE in the event that I continued composition!! Following this strategy, you can decide your own particular research paper subjects to expound on in a way that is fast and easy. 4. Work out your inquiries To get the BEST research, you need to make inquiries. Inquiries on inquiries on questions. The thought is that you get to the foundation of whatever you are discussing so you can compose a quality article on it. Suppose you have the inquiry: How would I compose an exploration paper? Would you be able to answer this without more data? 5. Do the examination It IS an examination paper, all things considered. In any case, you would prefer not to type every one of your inquiries into Google and pick the principal source you see. Few out of every odd snippet of data on the web is valid, or precise. Heres a way you can undoubtedly check your hot spots for validity: Look for the who, what, and when. WHO Who is the creator of the source? What are they known for? Do they have extensive experience with the subject they expounded on? Does the creator reference different sources? Are those sources believable as well? WHAT What does the Primary or Home page of a site resemble? Is it proficient looking? Is there an association supporting the data, and do they appear to be true blue Do they represent considerable authority in the subject? At the point when At the point when was the source produced — today, a week ago, multi-month, a year prior? Has there been new or extra data given since this data was distributed? Twofold check every one of your sources along these lines. Since this is an examination paper, your written work is good for nothing without different sources to back it up.

Harriet Jacobs essays

Harriet Jacobs essays Harriet Jacobs tells the story of her life in slavery in Incidents in the Life of a Slave Girl. Though born a slave in 1813 in North Carolina, Harriets early years were spent under a kind mistress. Her mother and father, both slaves, were permitted to live together as a family. Due to her fathers sought after carpentry skill, he was able to hire himself out for work, even though he was a slave. Because of her mistresses kindness and her familys living situation, she did not realize that she was indeed a slave until the age of six. Harriets understanding that she was someone elses property set in after her mothers death. In 1825, the kind mistress passed away and Harriett became the property of the mistresses five year old niece. Due to the girls young age, her father Dr. Flint, was in charge of Harriet Under the roof of Dr. and Mrs. Flint, Harriet had to endure his sexual abuse and his wifes jealous mistreatment. When she becomes involved with Mr. Sands, a white, unmarried attorney, she feels both freedom from Dr. Flint and guilt for violating her moral principles. She eventually has two children, Joseph and Louisa, by Mr. Sands. Dr. Flints jealousy of Mr. Sands causes him to become even more controlling of Harriet. It seems that because Harriet had such a positive early childhood, it was even more difficult for her to accept the intolerable position of life as a slave. When the situation is finally to much to bear, Harriet escapes her owner and goes into hiding in the garret of her grandmother's house in Edenton. She remained in this self-imposed hiding for seven years before escaping in 1842to the North in . Ten years later, Harriet is finally freed from slavery when her friend and employer Cornelia Willis, buys her freedom for the price of three hundred dollars. ...

3 questions - statistics related Assignment Example | Topics and Well Written Essays - 500 words

3 questions - statistics related - Assignment Example According to the table above, the mean average miles per gallon are 28.3792 when the total sample of purchasers is 24. In the same manner, out of the 24 sampled data, the sample variance is 8.859 whereas the sample standard deviation is 2.97643 as shown in the SPSS output table above. Under the sample of 24, which is below 30, the most appropriate statistical test, using the 0.5 significance level is the student’s t-distribution test. Under this test, the sample must be 30 or less, and the arithmetic mean is not normally distributed. According to the output table above, the Adjusted R squared is 0.030, meaning that only 3% of the variables explain the dependent variable Int. 2. The adjusted R squared helps in predicting how the regression model predicts responses for the explained observations. In this case, it is the fraction by which the variance of the errors that depends on the sum of squares is less than the variance of the dependent variables. Thus, as argued above, only 3% of the independent variables can predict the dependent variable statistically. When the ANOVA test is run in determining the means among populations, the f statistical value versus the critical value are determined. Under the corrected model, the f statistics is 3.227. Under the assumptions of the hypothesis tests, when the f statistic in attest is lower than the critical f value, then the null hypothesis is rejected. The value obtained means that under the purchase intensions implied by the data above, the null hypothesis is accepted and the independent variables in the states sampled explain the purchase variations. Also as shown in the second table, the means of the states in terms of consumptions are 37.0.18, 50.357, and 51.459 for the states IL, LA, and TX respectively. The standard error is also 4.339, 4.965, and 4.597 respectively as shown in the table

Is OIL a Resource Curse Essay Example | Topics and Well Written Essays - 250 words

Is OIL a Resource Curse - Essay Example This is because the citizens are unable to account on the spending of the money derived from exporting oil. Additionally, the resource leads to unprecedented rate of conflict. In fact, the wealth of resources in any country appears to correlate with conflict. This is because government relies on resources and delinks itself from people. This arises due to lack of accountability that could have been achieved by taxing. However, such governments do not need to tax its people as oil generates enough resources to run the government. This makes the government unaccountable to its people. However, there are ways in which some of the government are solving the resource curse. This involves use of some of the resources generated to offer incentives to the citizens. Moreover, the money is also channelled to social welfare to cater for the aged and less privileged in the society. In addition, some governments have focused on ensuring there is accountability in the sector. This takes place through offering information about the nation revenue and expenditure (Stapleton n.d). Additionally, other governments are in the process of developing legislation to address transparency in the oil sector. All these initiatives are believed to offer solutions to resource curse

Fast Food Restaurants And Problem Of Hygiene English Language Essay

Fast Food Restaurants And Problem Of Hygiene English Language Essay Today it is very important for food industry operators to concern about their level of hygiene as today s customer have become more alarmed about risks allied with food. This report will identify the problems of hygiene associated with various fast food restaurants, it will also highlight whether these problems of hygiene in fast food restaurants affects their sales, whether it changes the behaviour of customers and also some of the solutions that can improve the hygiene level of these fast food restaurants. In addition to this it also focuses on what consumers wants government to do to improve hygiene of these outlets. Analysis is made on Background Information of fast food Restaurants and problem of hygiene associated with them, which includes use of allergic ingredients and lack of cleanliness of workers, kitchens. Examples of hygiene issue that happened with one of the most reputed fast food restaurant Kentucky Fried Chicken and other restaurants like Arbys, Sonic, and Jack in Box etc are shown. Some of the Key findings of Research Conducted show that improper hygiene does affect the sales because it affects the behaviour of customer towards the restaurants which are not following proper hygiene system. Example of restaurants like KFC, Hamburgers, and Fresh City etc are given whose sales were cut down because of improper hygiene. In addition some of the respondents gave decent solutions which can be adopted by fast food restaurants to improve their hygiene level. Table of Contents No Particulars Page No 1 Introduction 2 Research Method Used And Its Limitation 3 Research Findings 4 Conclusions And Recommendations 5 References And Appendix Research Motivation and Problem Definition Whether it is onion rings or double cheese burgers or variety of sandwiches fast food is growing at the fastest speed as compared to other food types. This is because it is reasonable in price, quickly and readily available. Today fast food restaurants are also growing very fast in world, especially in urban areas. Some of the examples of biggest fast food restaurants are KFC, Subway, Mc Donalds, and Burger King Etc. But as today customers are more anxious about their food safety, concern over fatness, food poisoning and BSE (mad cow diseases) , the industry of fast food are forced to give attention on their sanitation factor that includes food quality ,cleanliness etc. Today more than 60 % of fast food restaurants have experts, which can also be called as benchmark for judging their cleanliness other than this various types of rules are putted into place by management ,inspectors , the food and drug administration etc, but still there are some issues which arise regarding their hygi ene and cleanliness. Problem of Using Allergic Ingredients The most common problem is the use of allergic ingredients in food making, but they dont express us which are they, some of examples are as follows; A sausage burrito available at Mc Donalds contains harsh chemicals and preservatives in addition to its normal ingredients. Beyond these the hash browns are cooked with animal products. The pasteurised eggs used by Mc Donalds in breakfast have, citric acid, monosodium phosphate and sodium acid pyrophosphate which are used to maintain colour. These were some issues about Mc Donalds, but there are more hygiene issues with other big fast food restaurants. In case of Burger King, there are three salads to choose, these salads can be dressed up by putting their Kens Fat Free Ranch which includes titanium dioxide (an artificial colour) and also harmful ingredient like monosodium glutamate. On the other end Subway which is considered as a healthiest sandwich centre has also some issue if the ingredients used by them is considered, the problem with Subway is that they dont use Whole meal bread for their sandwiches, their breads contains Ammonium sulphate (a fertilizer) and azodicarbonamide which is totally banned in UK , Australia because safety executive has acknowledged that the consumption of this may cause the problem of asthma, also most of meats of subway contains MSG and/or sodium nitrite. Even KFC, which is one of the biggest fast food Restaurants has also various issues about their ingredients, monosodium glutamate is added to the chicken gravy and rice. Today fries are not made with 100% potatoes, because most of the restaurants use frozen fries, fries become discoloured if it is kept freezing for longer period of time ,to avoid this sulphur dioxide is used to bleach the fries and give them fine white colour. So these was all about the ingredients that these fa st food restaurants adopt, there are also issues with their cleanliness of the restaurants, cleanliness of their workers, of the place where food is been made. Problem of lack of Cleanliness The other most common violation is the lack of cleanliness of employees as they might be hired on low salary, in some of the fast food restaurants workers do not wash their hands, there are no hand washing gel in their washrooms, some of restaurants have improper food holding temperature and also undercooked meat, unclean counters, tables and also the kitchen which can broaden germs that results in to food poisoning. This can be proved by the recent issue of KFC. KFC was fined 19000 pound after a cockroach was found eating chips at one of the most reputed branch in Britain located at Leicester Square in west end lane of London. It was also heard that during the inception the officer also found rat, flies and dried blood on the floor. The other example is Arbys one of the famous beef roast joint , the fact is dirty meat slices were found at two different locations in US which resulted into sickness of more than 70 people. Same happened with Jack in Box, 12 year girl was lapsed in coma after eating at the restaurant and $15.6 million settlement was awarded. In addition to these, Sonic comes on 3 among all restaurants following improper asepsis according to NBC, healthinspection.com reviewed 7000 hygiene issue records on Sonic and amongst them one was a black mold founded on an onion ring cover. Objective of Report: Thus the main objective of this report is to discern the problem of hygiene connected with fast food restaurant, whether the hygiene level of the fast food restaurants affects the behaviour of the customers towards them and at last does this hygiene level affects their sales, according to people what government should do to improve hygiene of fast food restaurants. In addition to these, the report will also discover some of the solutions that can be used by these fast-food restaurants to advance their hygiene factor. Literature Review; In past many researchers tried to make research around the issue of food hygiene and safety, for example a research was made by Green Street Berman on how a restaurant can improve its hygiene. While there was also another research made by the author Denise M Rennie, Lecturer in the Environmental Health and Housing Department, University of Salford, Salford, UK. He proposed in his report that personnel should be trained to improve hygienic matters in the food industry. He also mentioned in his report that training programs which are run more closely to the site of the work are more effective if they are supported by the reinforcement of hygiene message. The main objective of this report was derived by these early researches as they do not clarify that how improper hygiene of fast food restaurants affects consumer behaviour and how this affects the sales. Frame work of the Report Effects Research Methods and Their Limitation There are two basic methods used to collect information 1. Secondary method. 2. Primary method. Secondary data collection Method and Its Justification In order to collect secondary data Internet, Articles and various magazines are used. The reasons of using secondary method in order to carry out research are as follows; 1. It is less time consuming and easy to access; one can find information very easily. 2. Generally the cost to acquire information through secondary data collection method is less. Primary data collection Method and Its Justification In order to collect primary data, survey is carried out using QUESTIONAIRE. The reasons behind using questionnaire in order to carry out primary research are as follows: 1. The response can be gathered in a more effective way even more than interviews, because sometimes while taking interview one might forget to ask certain questions. 2. The response can be gathered from large proportion of people while in focus groups or interviews one can get information only from certain number of people. Manual method is used to get output information after analysing data. Sampling plan.; The criterion of this sampling plan will be as follow: People who often goes to fast food restaurants. Importance of hygiene of fast food restaurant to individual taking food from it. Some of the recommendations in order to improve the hygiene level of the restaurants. Sample size; Sample size used 50. Time Schedule; Total estimated time used to complete report will be 7 weeks Gantt chart Activities Week1 Week 2 Week 3 Week 4 Week 5 Week 6 Week 7 Identifying problem Primary data collection Secondary data collection Analysis Completion Limitations of the Research Method Used; In case of Secondary method data is collected from various Articles, magazines, newspapers etc are used. Various limitations related with this method are as follows; 1. The data available from secondary data were quite vague. 2. The writer of secondary data might be biased. 3. The sample worn to accumulate secondary data may be small. The organisation or company who collected secondary may not be reputable In primary method Questionnaire is used to collect data. There are various limitations linked with Questionnaire. Some of them are as follows; 1. One major disadvantaged of report is difference in response. Different individual gives different responses. So it was complicated to generalise the information. 2. It is time consuming method and costly, as it takes more time to find individuals who can give their time to fill questionnaire. It costs more to print questionnaire. 3. Some response might have given wrong information in a hurry to fill questionnaire. 4. Some responses given by respondent were incomplete. . Research Findings The Purpose of the research was to know whether hygiene level of fast food restaurants affects their sales, whether it affects the behaviour of consumer towards the restaurants, according to civic, what steps should government take to improve the sanitation and some of the improvement that can be adopted by Fast food restaurants outlets .Results indicate that, hygiene is the most important in every food especially in fast food which is not considered as healthy as other food. After making analysis, about the views of hygiene of people it can be understood that people do considered hygiene as an important issue in fast food restaurants, it do affect their behaviour about the restaurant which is not following proper hygiene altitude and at last if this restaurants are not having hygiene level up to what people desires, it will cut down their sales. This can be proved by following findings: 1. More than one out of two gave importance to hygiene factor of fast food restaurants. Research shows that in hygiene factor people first give to importance to the cleanliness of the workers who are preparing the food. In addition to these, People are also concerned about the kitchen where food is prepared. Other than this People give importance to the ingredients which are used to prepare food, handling, storage etc. while other 2 % of people gave more importance to taste than hygiene. 2. The study examines, that hygiene altitude of fast food restaurants do affects the behaviour of customer towards it, one of the example was given by a sample about a pizza place in Greece, the pizza maker mixed six types of sperm inside the pizza which created the health problem to the people who eat that, people stopped going at pizza place and at last the place was shut down. [Referred TO Questionnaire in Appendix]. In addition to these as mentioned in the Third point, it happened to KFC. Same was found in case of pizza hut , about 28 % of total random people said that they stopped going to the place because they consider the cleanliness of the eatery was not up to the mark , that led them to choose other chophouse. 3. (1.1) Kentucky Fried Chicken better known as KFC one of the best fast food restaurant faced decrease in sales and also minor difference in the points of hygiene level given by people after the issue of dirty kitchen and floor, that happened in one of the its branch at Leicester Square in London. The sales of KFC as shown in figure 1.3 (Appendix) had gone down by 4 % at the end of third quarter of September 6 2009, it s worldwide sales was $9843 which reduced to $9413 in 2009 ,5300 unit chain faced an operating loss and there was also decrease of 4 points in hygiene level given by people after the issue of hygiene problem, that means there is also decrease in people who want to eat food of KFC, which shows there is decrease in frequency of people in KFC because of change in their behaviour about KFC s hygiene. So in order to change the notion they organised a health campaign called Fresh Tastes Best it was a TV campaign. (1.2)Another example is closure of North Andover Franchise of Fresh City one of the famous restaurants for salads, after four year establishment, local news commented that the closure of Fresh city was because of lack of cleanliness and violation made by health board. (1.3)Other than this Mc Donalds also took its 169 franchises because they were not performing well and their sales were continuously going down, the reasons were lack of satisfaction of customers and that was because of lack of cleanliness and improper quality of product. (1.4)Other example is of famous Hamburger, the sales of hamburger cut down because of lack of cleanliness. 4. As per figure 1.4 (Appendix) 50 % of individuals think that government should increase fine to improve the hygiene in fast food restaurants , while other 20 % of people that government should force the owner of the restaurant to close it , if it is following improper hygiene. Other 17 % of respondents said that government should force the fast food restaurants to organise compulsory training sessions for staff, to improve sanitation level of restaurants. Rest 13 % of respondents alleged that administrative should increase the frequency of health officers visiting all fast food restaurants to know , whether they are following proper hygiene altitude. While in case of improvement in hygiene stage of fast food restaurants, there are number of recommendations given by respondents, some of them are as follows, Recommendations given by samples 1. One third of total sample indicated that the fast food restaurants should clean their floors regularly and kitchen regularly. 2. About 10 % people said workers should be given more training in regardless to wash their hands before and after making food and they should have at least one separate sink for washing hands only or they should wear plastic gloves while preparing food, they should keep their hands away from nose, hair, ears all time and should use new gloves with new order. In addition to these workers should wear cap while making food. 3. Some of the people suggested to change the storage system of restaurants, they suggested to keep separate storage for each food so that the risk of cross-contamination which leads bacterial disease such as Salmonella can be concentrated, additionally all frozen food must be stored 5 degree Celsius. 4. About 10 % people suggested that the restaurants should recruit more people in regardless with cleaning. 5. Couple of people suggested, the restaurant that is not following proper scepticism should follow other restaurant that is following proper hygiene and try to implement it. 6. Some people indicated that restaurant should make all food in front of us And also they can advance the fast food by putting some more fresh fruits in it. Conclusion -After making above analysis following conclusion can be made; These days, the problem of hygiene in fast restaurants have increased, which includes several problems like lack of cleanliness especially in kitchen, various harmful chemical mixed ingredients, dirty employees working there, uncooked food etc. And all big reputed restaurants like KFC, MC Donalds, Subway, and Pizza Hut etc were spotted for following improper sanitary level. The reason behind this careless attitude might be to reduce the cost of getting pure ingredients or laziness of workers to maintain proper asepticism or lack of awareness of local manager. But today as people have became extra apprehensive towards the peril linked with fast food and as improper hygiene of the restaurant do affect their behaviour towards the food outlet, it is very necessary for the restaurant to give attention to their hygiene if not than it will be a time when no one will go to eat at fast food restaurants. Some of the big restaurants like KFC , Mc Donald s , Fresh City etc started showing out these picture as there was huge decrease in sales in KFC after it was noticed following improper hygiene, many franchisee of Mc Donalds and famous restaurant Fresh City were closed because of same reasons. In addition to this government should become tighter towards those who are not following suitable sanitation by implement new rules and regulation APPENDIX Figure 1.1.

Wilbur and Orville Wright and the First Airplane Essay -- dream, aircra

In 1903, I can only imagine that the single thought inside of both Wilbur and Orville Wright’s minds was to get their airplane off the ground. Because of their dream of heavier-than-air flight, mankind has gone from a flight of 120 feet, in an aircraft designed largely out of wood, using bicycle drive technology (World Digital Library, 2013), to a spacecraft that is about to leave our solar system (Voyager I). To quote American author, Napoleon Hill (1992), â€Å"Whatever the mind of man can conceive and believe, it can achieve.† When we stop to consider how far we have come in just over one hundred years, is it even possible to conceive what air travel might look like a hundred years from now? From the Wright Flyer to the aircraft we fly today, they all started as a dream that later turned into a design. NASA is not sending astronauts into space at the moment, but that has not stopped the engineers at NASA from working on advanced aerodynamic designs and technologies that would help us achieve the dream of traveling farther, faster and higher. Improved materials such as carbon-fiber give an aircraft lighter weight, improved performance and lower fuel consumption. NASA’s newest design in carbon-fiber is called â€Å"PRSEUS† (Pultruded rod, Stitched, Efficient, Unitized Structure), a material that will be stronger than current carbon-fiber technology and will greatly reduce the need for rivets and other fasteners that lead to structural fatigue. NASA believes this new material will help Boeing achieve its goal of an aircraft of blended wing design (Sloan, 2011).

The r? value of 0. 9416 re presents that there is a good relationship in the data between the concentration of sucrose solution and the percent change in mass. The relationship between the data can also be proven by the error bars, representing the standard deviation from the data points and the amount of uncertainty.With the small error bars we know that the data is reliable; although as the last few points overlap this indicates that the data is similar. Conclusion: I found that as the concentration of sucrose increased, the change in mass and percentage of the change in mass decreased. This data did support the hypothesis, as we knew from the term osmosis. Osmosis is the process of diffusion of water molecules from an area of higher concentration to lower concentration. The concentration gradient between the potato and the sucrose solution lead to the amount of molecules coming in and out of the potato.Therefore, the data supports the hypothesis as when the water concentration was lower in the potato than in the sucrose solution, the water molecules moved through the semi-permeable membrane into the potato which caused it to gain weight. With a higher concentration of water in the potato, the result would be the opposite. Hence the prediction that the lower the concentration of sucrose, the higher the final weight of the potato was reinforced. The hypothesis is supported by the evidence of the graph. With a concentration of 0. M sucrose solution the increase in the change of mass was 1. 6g and a percentage change of 22. 3%. In comparison, the 0. 8M sucrose solution had a change in mass of -3. 5g and a loss of 31. 7%. Although in Figure 1 the r? value gives the impression that the data is very reliable, some of the error bars do overlap. While observing the data there are no outliers present, although when inspecting the change in mass the development between the 0. 8M concentration of sucrose and the 1. 0M numbers slightly increase; when accurately they would continue decreasing.This may perhaps be the result of certain potential errors. Evaluation: My results, while mostly concrete, had particular places where a few errors could have occurred; as they diff from the hypothesis that with a higher concentration of glucose there should be a decrease in the change of mass. As our class only had a certain amount of time to complete the lab, each group completed the lab with three different sucrose solutions. At the end of collecting our data, our classes’ results were compiled together to compare.An error is the fact that each group’s statistics came from different potatoes. As different potatoes were used, the pores in the membrane of each potato are different, causing a different amount of water molecules to be able to pass through and into the solution. This could prove the overall data to be unreliable. To fix this deviation, with more time a group can complete their own lab with the full data with a single potato. Another error is the factor of te mperature. Temperature affects osmosis as with a higher temperature the molecules are moving faster, causing osmosis to increase.As we left our beaker s with the potato cores inside the classroom overnight, the classroom temperature may have increased or decreased which would affect the rate of osmosis inside the beaker. Due to the fact that it’s September, we can assume that the classroom temperature would decrease overnight; including the consequences that perhaps a window or door would have been left open. As the temperature in the classroom decreased, the rate of osmosis did as well. To fix this normal variation error, the temperature of the classroom could be recorded as we placed the beakers around the classroom to be left.Overnight it would be made sure that no windows or doors are left open, and that the temperature stays the same throughout the experiment. A systematic error has to do with the scales that were used. The scales were a necessity for this lab; itâ€℠¢s important that they’re working correctly. While planning for this lab not at one point were the scales that we were using checked to make sure that they were fully functioning. This could establish the scale giving off false numbers which changes our entire experiment. At the beginning before proceeding with the lab it must be made sure that the equipment is regularly checked and operative.To do so, we can take an object that we can identify the weight of, and test it on the scale to make sure it’s correct. As an extension to this investigation, it could be completed again but testing osmosis with more of a variety of the amount of sucrose solution- it could exceed a concentration of 1M to extend to 2M. This experiment could also be completed using different time frames; instead of letting the potatoes rest for one day they could be let stand for one hour, or two hours to test how osmosis works within this shorter time frame.To fix our errors stated above, we must f irst make sure that all of our equipment is running properly and that the temperature of the room does not vary overnight.
