Summary of I Am Because We Are pg 338-pg356 Essay

Summary of I Am Because We Are pg 338-pg356 - Essay Example Woodson claims that more than fifty years ago at his time, something was wrong with the path that the African American were being educated, and this provided an impetus for the Afrocentric approach to the education in America. In this article, Molefi examines the scope and nature of this approach by Woodson. He shows its necessity and further suggests how it can be developed and disseminated all through the levels of education (340). The two guide propositions that this article makes use of are the definitions of education and school. Education is defined as a fundamentally social phenomenon that purposes to socialize a learner. School is a reflexive of societies and develops from them. Afrocentricity is defined as a frame of reference that enables someone particularly a researcher to develop of phenomena in regards of the African person. Molefi emphasizes that the afrocentricity should not be mistaken to a black version of Eurocentricity. Eurocentricity is generally based on the notion of white supremacist that purposes to protect white privilege and the importance in economics, education and politics among others (347. The issue of Multiculturalism has also been featured illustrating that education must begin with a proposition that diverse people have contributed to the development of education. The American education does not include the African ethnic groups showing how the systems have victimized the teaching force (344). However, Afrocentricity gives the Americans an opportunity to examine the African person perspective in the society and globally. Afrocentricity is not anti-white like some people claim but is pro-human. The Afrocentric curriculum aim is not to divide America, but to make it flourish. 348. In the second article, Learning to talk the race, Cornel west talks about an event that happened in Los Angeles explaining why it is neither a race riot nor a rebellion associated with a

Absorption of Nuclear Radiation Essay Example for Free

Absorption of Nuclear Radiation Essay The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values, putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph was created, it was possible to apply a linear fit and using that, it was possible to determine the slope of the line. The slope was then used to calculate the mass thickness attenuation factor which ended up being (0.197m  ± 0.008) g/cm2. This value was then compared to the theoretical value of 0.2 g/cm2 through a percent difference computation. The percent difference was found to be a mere 1 percent which allowed for the conclusion that the results were very accurate. This was further supported by the graph that was generated because it showed the trend that was expected to be seen. Overall, the experiment was quite successful with only one minor, possible source of error and that being a slight misreading of the intensity apparatus which would explain the 1 percent difference. Objectives: In this experiment there were a couple different objectives. The first objective was to gain an understanding of mass thickness attenuation through an investigation using beta rays and polyethylene sheets of different thicknesses. The second objective was to gain practice with new and unfamiliar laboratory instruments. Experimental Procedure: For this experiment, there were multiple parts to the procedure. The first part was to find the voltage at which the specific G-M counter operates. This was done by first setting the timer to auto and placing the beta tray in the G-M tube. Next, the counter set up was powered on, reset, and started by pushing the button labeled â€Å"count.† The voltage was increased in small increments until the unit began to continue to increase on its own. Once this occurred, it meant that the threshold voltage had been determined. After this, 75 volts was added to the threshold voltage and the machine remained at this level for the rest of the experiment. The next part of the procedure was to determine the background radiation that was present within the environment. This was done by simply turning on the counter, at the previously determined voltage, and taking a ten minute measurement. Once this was completed it was possible to determine what radiation was coming from the samples and what was just coming from the environment. The relative error for the intensity number found during this part of the procedure was then calculated and both values were recorded. The next part of the procedure was performed to discover the mass thickness attenuation coefficient of beta rays through polyethylene sheets of varying thickness. This was done by placing the beta source in the second level of the counter, placing the polyethylene sheet in the unit also, turning on the counter, and taking a one minute reading. This same procedure was repeated 6 more times, with 6 other polyethylene sheets of varying thicknesses. Each count for all seven polyethylene sheets was recorded, along with the varying thicknesses of the sheets, and both values were used in the final calculations. Experimental Results: The plot that was generated from the results can be found on attachment one. The calculations to come to these results can be found on attachment two. Data Analysis and Discussion: In this experiment an apparatus was used to observe the way the mass thickness attenuation factor changed when multiple polyethylene sheets of a variety of thicknesses were used. The apparatus that was used, measured the intensity of the radiation in a unit know as counts. Because it is not possible to completely exclude the background noise that is naturally occurring in the environment, it was necessary to take this into account when performing the calculations. For each polyethylene sheet that was used (of which there were seven), the I_corr was calculated. This was done by taking the intensity value given by the apparatus, subtracting the background noise value that was found previously, and then dividing by ten. Once all of these values were calculated, they were then used to find the natural log of I_corr, which ended up being the y value on the graph. After generating the ln(I_corr) versus thickness graph, a linear fit was applied. It was from the information provided by the linear fit that allowed comparisons to be made between the theoretical and experimental values. The slope of the linear fit was used to calculate the experimental mass attenuation factor and its error which was found to be (0.197m  ± 0.01) g/cm2. This value was then compared to the theoretical value of 0.2 g/cm2 through the percent difference equation. The percent difference was found to be 1.35%. The most probably source of error that caused this percent difference is a slight misreading by the apparatus used to measure intensity. In order to have decreased the possibility of this happening, the unit should have been tested beforehand to ensure that it was working at its full potential. Because the percent difference is so small, however, it can be concluded that not only are the experimental results precise, but that they are also very accurate and can be accepted as the mass attenuation factor. This is also supported by the graph. The value for intensity seen on the graph decreases in an almost linear fashion, as the thickness of the polyethylene sheets increased as was expected. This indicated that as the polyethylene sheets increased in thickness, the intensity of radiation decreased, suggesting that more beta rays were being absorbed. Conclusion: Overall, the objectives of the experiment were accomplished. Not only was mass thickness attenuation looked at in great detail throughout the experiment, but it was also investigated further after the fact through comparison of the theoretical and experimental values. According to the results, the beta rays scatter and absorb at a mass thickness attenuation factor of (0.197m +/- 0.01) g/cm2. When this value was compared to the theoretical value of 0.2 g/cm2, it was concluded that indeed it was accurate because it had a percent difference of a mere 1 percent. Furthermore, this percentage could be explained by a simple misreading of the unit used to find the intensity values. Had the unit not made any slight misreading, the percent difference would have been even smaller and the experiment would have been even more successful.

William Wordsworth Essay example -- English Romantic Poets Biography B

William Wordsworth William Wordsworth is considered to be the greatest among all of the English Romantic poets. Although he did not always get the recognition that he rightfully deserved in the early part of his career, only through trials and tribulations did he reach the pinnacle of the literary world. "Wordsworth said of "the Prelude" that it was "a thing unprecedented in the literary history that a man should talk so much about himself": " I had nothing to do but describe what I had felt and thought" and " therefore could not easily be bewildered.""(Sinatra, 1) Wordsworth's innovative concept of nature and his frank exploration of his feelings and philosophical ideas created his own original poetic theory. Asserting himself as a noted figure in the English literary world, his accomplishments are unprecedented through out the world. William born at Cockermouth in the Lake District of Cumberland, England to John and Anne Cookson Wordsworth, on April 7th of 1770. Unfortunately Wordsworth lost his mother at the early age of eight, and the loss of his father five years later made him depend on his uncle for a good education." Schooling at Hawkshead was followed by matriculation at Cambridge University, where he entered St. John's college in 1787. Upon Graduation he revisited his beloved France to both learn the language and to develop himself into a man."(Frank N. Magil et al, 2200) His primary goal was the learn French due to his admiration of French society. "Much besides language, however drew the attention of young Wordsworth, much to the influence of his surroundings, William found himself developing two passions, one for Annete Vallon and the other for the French Revolution."( Frank N. Magill et al, 2200) ... ..., with his writing. Affecting the way I think and see things in the world. His depiction of nature adds rippling effects to minds young or old, the way he puts emotion into every word makes a person think of how deep of a person Wordsworth really was. William Wordsworth truly revolutionized both the Literary and artistic worlds. Bibliography: ï‚ · Drabble. The oxford companion in English Literature.

Learning to Read and Write Summary Essay

In â€Å"Learning to Read† an excerpt from his autobiography, Frederick Douglass writes about the steps he took to learn to read and write. He shows all the steps in this excerpt. He was a slave in a house; he didn’t have any opportunity to go to school or get any educations but the mistress in the house helped him and taught him the alphabet. But then Douglass’s master asked his wife to stop teaching him. She listened to her husband and turns into inhuman, an evil woman, Douglass could not recognize her anymore. Douglass writes, â€Å"She finally became even more violent in her opposition than her husband himself† (36). She changed and she became more evil, more violent than the master. But then that didn’t make Douglass stop and stand hopelessly, he found another way to learn. He tricked a kid from his neighborhood and makes that kid teach him how to read and it went well. After that he continued to find more way to learn, and try improving his reading. He found a book named â€Å"The Columbian Orator†. He used every opportunity he got try to read this book and learn the words in there. That was the final step that he took to learn to read. Some years later, after he went to a shipyard and saw and board with words, letters, and he wanted to write. He tried to copy the letters from the board. He didn’t stop; he wanted to know more about writing. He found a boy and asked him to teach him write. The boy taught him to write all the alphabet letters. Finally, the last step he took to learn to write was that he took a book and copy all the words in there and try to remember what the words looked like. That was long and not so easy time for him to learn how to read and write but it didn’t stop him from his interest in reading and writing. Even though he didn’t have any opportunity as a slave to have education, he became strong and found any way that could help him to learn. He keep reading and writing until he could read and write excellently. Finally he succeeded in learning how to write. Douglass, Frederick. â€Å"Learning to Read.† The Norton Mix. Ed.

Introduction to Marketing

PrimaryQuestionnaires: Questionnaires consist of a list of questions that can be used to obtain feedback such as a spoc which is used at colleges to find out information such as if a student is enjoying their course etc. The Oldham College recently gave all of the students a spoc which was to get their feedback about the college for e.g. if they feel safe and satisfied by their course. By doing a spoc the college is able to find out how many students are satisfied with their course, tutors and so on; this helps the college as they can use their research to see who’s happy and who isn’t, thereon they are able to make changes if necessary for their market plan.Suggestion box: A suggestion box is a box that is used for people to put suggestions inside, this is a good way for a college to get and consider suggestions as people may want to make their suggestions anonymously. The Oldham College students are able to make suggestions to the college through their suggestion box; if the majority of the students make the same suggestion then the college could consider making changes in their marketing plan.Student reps: The students union of The Oldham College are able to talk with each other and hear out the students suggestions, ideas and any complaints there may be; therefore they are there to put forth suggestions or complaints on behalf of the students, if the college feels that the suggestions made are necessary or that it may be of benefit they could consider making changes to their marketing plan to satisfy their students.SecondaryGov stats: Government statistics are official data collected from colleges, schools etc. which is released to the public; a person can then see which college has better success rates and how many people join them and so on. When government statistics are released showing the achievements and how  many students are joining the different colleges such as their competitor’s, this helps The Oldham College to evaluate t heir different aspects; this allows them to take good measures.Newspapers: Newspapers are a good way of collecting data, such as how colleges advertise their courses to the public; when competitors advertise courses in the newspapers and/or magazines The Oldham College is able to see what kind of courses they advertise and how; for e.g. if it’s plain text or images and so on. This gives them an idea of what courses are mainly being advertised and will help their marketing plan as they can do the same or do it and improve their advertising compared to their competitors.Competitor’s website: A competitors website can be looked at by its rival such as The Oldham College as they can see their competitor’s website to gather data from them such as what courses they offer and how they advertise their courses through their website; this helps The Oldham College’s marketing plan as they are able to see if there is any way they can improve their way of advertising and even their website with the aim of attracting new students to the college, this would be done through making changes to their existing marketing plan. Introduction to Marketing What is marketing? Marketing is the function that connects businesses to their target audiences’ needs. It is how a business presents and distributes their product to their audience. For example, a business can market their product by advertising it to the public. This can be seen in many forms of media; such as: on television, via web, posters or on billboards.Marketing is the management procedure in which the product or service is moves from concept to the customer. It includes the co-ordination of the 4 P’s of marketing: product, price, placement and promotion. [tutor2u.net]The concepts of marketing Production The production concept is when businesses are more focused on making profit from their sales; the quality isn’t necessarily important as the company’s main concern is making sales. For instance, supermarkets such as Sainsbury’s and Tesco distribute their own products to the public. The production of products is also kept at a low cost.Produ ct The product concept is when businesses focuses more on the quality of the product rather than how many of them are being sold. The business is more concerned with the high standards of the product set by customers and is prioritised. For example, smartphones have become more popular within society because of their many features.Selling The selling concept is when businesses are concerned with promoting a product even further to increase sales. For example, Coca-Cola advertises the same products over and over again; they introduced names to target people with that certain name.Marketing The marketing concept is when a business allows their customers to decide on the features of their product or service, before it is created. A business would use market research and use research & development to discover the customers’ needs and wants for a product/service.Aims and objectives of two contrasting businesses Private sector business: Apple Inc. Apple’s objectives are to c ontinuously sell the same products that are of high standards and quality.Market leadership in Apple Market leadership is when a business has the most customers/users due to their sales or service. Steve Jobs suggested these techniques to assist in becoming a market leader Be in possession of and have control over the relevant technology Take in and implement better technologies immediately as soon as they have availability, regardless of whether or not there are organisations using them beforehand Create new technologies/products before anyone else and make it an industry standardBrand awareness in Apple Apple raises brand awareness by creating adverts and allowing their stocks to be released online. This can be effective because potential customers will know whether not to purchase a product based on the stocks.Perceptions of customers in Apple Customers of Apple are aware of the product by seeing advertisement and by live streaming press conferences that are held by Apple. The ef fectiveness of live press conferences is that the potential customers will know what features the product has.Public sector business: National Health Service (NHS) Their aims are to aid people who are applicable to use their service. They are non-profit and are Governmental, which means that the Government funds the NHS by using a portion tax-payers’ money.Market leadership in the NHS The National Health Service is the only health service that is free in the country. This makes it the market leader.Awareness in the NHS One way in which the NHS raises awareness is by endorsements from the news or magazines. This can be effective because the news is something the majority of the public intakes.Perceptions of users in the NHS Users of the NHS become aware of this industry via real-life happenings. Some of these perceptions can be negative; as recently, a celebrity received a free surgery which wasn’t life threatening in any way. It wasted tax-payers’ money and the majority of the nation was unimpressed by this.
