Warren Buffet Essay Example for Free

Warren Buffet Essay Executive Summary: Warren E. Buffett is one of the worlds richest men with a net worth estimated at $44 billion by Forbes magazine. Buffett is known for his patient approach to investing and making long-term investments in steady, predictable industries that generate positive cash flow. It was announced that MidAmerican would purchase the regulated electric utility PacifiCorp from Scottish Power, for $5.1 billion in cash and $4.3 billion in liabilities and preferred stock. This would be the second largest purchase of his career. After the announcement, stock prices for both PacifiCorp and Berkshire Hathaway increased, by 2.4% and 6.28% respectfully, which suggests market approval for the acquisition of PacifiCorp. Problem: From the increase in stock price, we can assume that investors believe that the deal was a fair price and that acquiring PacifiCorp was a good investment to benefit Berkshire Hathaway. In fact the market added more value enhancement to Scottish Power than Berkshire, which leads investors to consider why Scottish Power gained more benefit than Berkshire Hathaway and if Berkshire Hathaway paid a reasonable price. Analysis: From Exhibit A, on the following page, we can analyze the range of values for PacifiCorp. From this we can see that the only significant various between median and mean value arises in EBIT, which indicates outliers for revenues, operating expenses, or depreciation. Intrinsic value refers to the actual value of a company or stock without reference to its market value and is calculated through the discounted cash flow of a business during its remaining life. Intrinsic value can also encapsulate how well the company is run, cash flow, and management competency. According to Buffett, intrinsic value indicates the â€Å"present value of the future expected performance† and can be predicted through calculating the discounted cash flow of a business for its remaining life. This estimate allows Buffett to identify stocks or businesses that are undervalued. Other alternatives to intrinsic value as book value and accounting profit, which can fall short when determining what  the inve stment is really worth and accurate aggregate value. Stock price is the most accurate way to determine a company’s present value of expected cash flows. However, as a private company, the market value of PacifiCorp could not be determined by its share price. In order to calculate Berkshire’s discount rate we must use the capital asset pricing model (CAPM) to determine a required rate of return. This is calculated by adding the risk free rate (yield on a U.S. Treasury Bond) to beta multiplied by the difference of the expected market return and risk free rate. A U.S. Treasury Bill has a yield of 5.76%, Berkshire’s beta is .7, and expected market return is 10.5%, therefore the rate of return would be 9.07%. This can then be used to determine the present value of this investment over one year, $4.68 billion. Therefore, Berkshire’s offer to purchase PacifiCorp for $5.1 billion is slightly overvalued, but still a fair price for both companies. Berkshire Hathaway performed tremendously well between the periods of 1965 and 1995, where its stock prices grew 24%, in comparison to the SP 500, which averaged 10.5% a year. This is a remarkable occurrence to beat the market growth rate, and is even more rare to beating it for 30 consecutive years. Berkshires shares have been among the highest-priced shares on the New York Stock Exchange. Berkshire also holds majority shares in Coca-Cola Co., American Express Co., Gillette Co., and Wells Fargo, all of which have had consistent growth and stability over the companies’ lifetime. Buffet’s philosophy contradicts many of the common principles the average investor swears by. His philosophy relies on little diversification and avoiding risk. The biggest stand out in this regard is his dislike of broad diversification. Instead referring to diversification as protection against ignorance and an unstable market, Buffet believes it to be the lazy way out. Buffet believes that we must invest in our expertise areas and therefore will have greater knowledge in a handful of stocks and should not diversify our portfolio by purchasing shares of companies we know nothing about. While I understand where Buffet is coming from, this seems very risky. Recommendation This case shows a prime example of the link between a company’s valuation and the behavior of investors in the capital market. Through Berkshire Hathaway`s increase in share price the investors reflected that they agreed with the deal through an increase in share price. And even though it seems odd that both the selling and buying company should have an increased share price, we can see through calculating PacifiCorp’s intrinsic value, that the purchase was reasonable. This acquisition also added more diversification to Berkshire’s investment portfolio to provide more stable returns.

Carbon nanotubes

Carbon nanotubes Introduction Carbon nanotubes are the allotops of carbon , they have a cylindrical nano structure. Nano structure are construct with a length to diameter ratio of 28000000:1 , this is significantly larger than any other material. They have many novel properties and are many useful in nanotechnology , electronics , optics , material science and architectural field. They have great strength and unique electrical properties . However their useusge is limited in day to day life because of their toxicity . includes the spherical bucky ball (c60). It is often see that end of nanotube are hemispherical buckyball structure . It is qurt intresting to know that the radius of a nanoube is approximately 1/50000of the human hair. The nature of the bonding of a nanotube is described by appling orbital hybridation . They have sp2 bonds as graphite have . Most single-walled nanotubes (SWNT) have diameter close to 1nanometer, with a tube length is many millions of times longer. The structure of a SWNT can be conceptualized by wrapping a one-atom-thick layer of graphite called graphene into a seamless cylinder. The way the graphene sheet is wrapped is represented by a pair of indices (n,m) called the chiral vector. The integersnandmdenote thenumber of unitvectoralong two directions in the honeycomb crystal latticeof graphene. Ifm= 0, the nanotubes are called zigzag. Ifn=m, the nanotubes are called armchair. Otherwise, they are called chiral. ( The (n,m) nanotube naming scheme can be thought of as a vector (Ch) in an infinite graphene sheet that describes how to roll up the graphene sheet to make the nanotube.Tdenotes the tube axis, anda1anda2are the unit vectors of graphene in real space.) Single-walled nanotubes exhibit electric properties that are not shared by the multi-walled carbon nanotube (MWNT) . Single-walled nanotubes are the most likely candidate for miniaturizing electronics beyond the micro electromechanical scale currently used in electronics. The most basic building block of these systems is the electric wire, and SWNTs can be excellent conductors. Application of SWNTs are useful in the development of the first intramolecularfield effect transistor(FET). Production of the first intramolecularlogic gateusing SWNT FETs has recently become possible .To create a logic gate you must have both a p-FET and an n-FET. Because SWNTs are p-FETs when exposed to oxygen and n-FETs otherwise, it is possible to protect half of an SWNT from oxygen exposure, while exposing the other half to oxygen. This results in a single SWNT that acts as a NOT logic gate with both p and n-type FETs within the same molecule. Single-walled nanotubes are still very expensive to produce, around $1500 per gram as of 2000, and the development of more affordable synthesis techniques is vital to the future of carbon nanotechnology. If cheaper means of synthesis cannot be discovered, it would make it financially impossible to apply this technology to commercial-scale applications. Multi-walled nanotubes (MWNT) consist of multiple rolled layers (concentric tubes) of graphite. There are two models which can be used to describe the structures of multi-walled nanotubes. Russai doll model, sheets of graphite are arranged in concentric cylinders, e.g. a (0,8) single-walled nanotube (SWNT) within a larger (0,10) single-walled nanotube. In theParchamenmodel, a single sheet of graphite is rolled in around itself, resembling a scroll of parchment or a rolled newspaper. The interlayer distance in multi-walled nanotubes is close to the distance between graphene layers in graphite, approximately 3.3 Ã…. The special place of double-walled carbon nanotubes (DWNT) must be emphasized here because their morphology and properties are similar to SWNT but their resistance to chemicals is significantly improved. This is especially important when functionalizationis required (this means grafting of chemical functions at the surface of the nanotubes) to add new properties to the CNT. In the case of SWNT, covalent functionalization will break some C=C, leaving holes in the structure on the nanotube and thus modifying both its mechanical and electrical properties. In the case of DWNT, only the outer wall is modified. DWNT synthesis on the gram-scale was first proposed in 2003by the CCVD technique, from the selective reduction of oxide solutions in methane and hydrogen. A nanotorus is theoretically described as carbon nanotube bent into atorus(doughnut shape). Nanotori are predicted to have many unique properties, such as magnetic moments 1000 times larger than previously expected for certain specific radii. Properties such as magnet moment, thermal stability etc. vary widely depending on radius of torus. Carbon nanobudare a newly created material combining two previously discovered allotropes of carbon: carbon nanotubes and fullerenes. In this new material fullerene-like buds are covalently bonded to the outer sidewalls of the underlying carbon nanotube. This hybrid material has useful properties of both fullerenes and carbon nanotubes. In particular, they have been found to be exceptionally good field emitters. In composite materials, the attached fullerene molecules may function as molecular anchors preventing slipping of the nanotubes, thus improving the composites mechanical properties. Strength Carbon nanotubes are the strongest and stiffest materials yet discovered in terms oftensil strenghtandelectic modulas respectively. This strength results from the covalent sp ² bonds formed between the individual carbon atoms. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63gigapascal(GPa). (This, for illustration, translates into the ability to endure tension of 6300kg on a cable with cross-section of 1mm2.) Since carbon nanotubes have a low density for a solid of 1.3 to 1.4g ·cm−3,itsspecific strenghtof up to 48,000kN ·m ·kg−1is the best of known materials, compared to high-carbon steels 154kN ·m ·kg−1. Under excessive tensile strain, the tubes will undergoplastic deformation, which means the deformation is permanent. This deformation begins at strains of approximately 5% and can increase the maximum strain the tubes undergo before fracture by releasing strain energy. CNTs are not nearly as strong under compression. Because of their hollow structure and high aspect ratio, they tend to undergobuckingwhen placed under compressive, torsional or bending stress. Kinetic Multi-walled nanotubes, multiple concentric nanotubes precisely nested within one another, exhibit a striking telescoping property whereby an inner nanotube core may slide, almost without friction, within its outer nanotube shell thus creating an atomically perfect linear or rotational bearing. This is one of the first true examples ofmolecular nanotechnology, the precise positioning of atoms to create useful machines. Already this property has been utilized to create the worlds smallest rotationalmotor. Future applications such as a gigahertz mechanical oscillator are also envisaged. Because of the symmetry and unique electronic structure of graphene, the structure of a nanotube strongly affects its electrical properties. For a given (n,m) nanotube, ifn=m, the nanotube is metallic; ifn−mis a multiple of 3, then the nanotube is semiconducting with a very small band gap, otherwise the nanotube is a moderatesemiconductor. Thus all armchair (n=m) nanotubes are metallic, and nanotubes (5,0), (6,4), (9,1), etc. are semiconducting. In theory, metallic nanotubes can carry an electrical current density of 4 Ãâ€" 109A/cm2which is more than 1,000 times greater than metals such ascopper . All nanotubes are expected to be very goodthermal conductorsalong the tube, exhibiting a property known as ballistic conductor, but good insulators laterally to the tube axis. It is which transmits 385 W ·m−1 ·K−1. The temperature stability of carbon nanotubes is estimated to be up to 2800 °C invacuumand about 750 °C in air. Potential and current applications The joining of two carbon nanotubes with different electrical properties to form adiodehas been proposed The strength and flexibility of carbon nanotubes makes them of potential use in controlling other nanoscale structures, which suggests they will have an important role innanotechnologyengineering. The highest tensile strength an individual multi-walled carbon nanotube has been tested to be is 63GPa. In electrical circuits Carbon nanotubes have many properties—from their unique dimensions to an unusual currentconductonmechanism—that make them ideal components of electrical circuits. For example, they have shown to exhibit strong electron-phonon resonances, which indicate that under certain direct current (DC) bias and doping conditions their current and the average electron velocity, as well as the electron concentration on the tube oscillate at terahertz frequencies[. These resonances could potentially be used to make terahertz sources or sensors. Nanotube based tranistorhave been made that operate at room temperature and that are capable of digital switching using a single electron. One major obstacle to realization of nanotubes has been the lack of technology for mass production. However, in 2001 IBM researchers demonstrated how nanotube transistors can be grown in bulk, somewhat like silicon transistors. Their process is called constructive destruction which includes the automatic destruction of defective nanotubes on thewafer. The IBM process has been developed further and single-chip wafers with over ten billion correctly aligned nanotube junctions have been created. In addition it has been demonstrated that incorrectly aligned nanotubes can be removed automatically using standardphotolithoraphy equipment. The first nanotube integrated memory circuit was made in 2004. One of the main challenges has been regulating the conductivity of nanotubes. Depending on subtle surface features a nanotube may act as a plainconductoror as a semiconductor. A fully automated method has however been developed to remove non-semiconductor tubes. Most recently, collaborating American and Chinese researchers at Duke University and Peking University announced a new CVD recipe involving a combination of ethanol and methanol gases and quartz substrates resulting in horizontally aligned arrays of 95-98% semiconducting nanotubes. This is considered a large step towards the ultimate goal of producing perfectly aligned, 100% semiconducting carbon nanotubes for mass production of electronic devices. Another way to make carbon nanotube transistors has been to use random networks of them. By doing so one averages all of their electrical differences and one can produce devices in large scale at the wafer level.This approach was first patented by Nanomix Inc (date of original application June 2002). It was first published in the academic literature by theusa navel reacherch labority in 2003 through independent research work. This approach also enabled Nanomix to make the first transistor on a flexible and transparent substrate. Nanotubes are usually grown on nanoparticles of magnetic metal (Fe, Co), which facilitates production of electronic (spinotic) devices. In particular control of current through a field-effect transistor by magnetic field has been demonstrated in such a single-tube nanostructure. Large structures of carbon nanotubes can be used for thermal management of electronic circuits. An approximately 1mm-thick carbon nanotube layer was used as a special material to fabricate coolers, this materials has very low density, ~20 times lower weight than a similar copper structure, while the cooling properties are similar for the two materials. As paper batteries Apaper battery is abatteryengineered to use a paper-thin sheet ofcellulose (which is the major constituent of regular paper, among other things) infused with alignedcarbon nanotubes .The nanotubes act aselectrods; allowing the storage devices to conduct electricity. The battery, which functions as both a lithium-ion battery and asupercapacitor can provide a long, steady power output comparable to a conventional battery, as well as a supercapacitors quick burst of high energy—and while a conventional battery contains a number of separate components, the paper battery integrates all of the battery components in a single structure, making it more energy efficient. Solar cells Solar cells developed at the new jerrsyinstitute of technology use a carbon nanotube complex, formed by a mixture of carbon nanotubes and carbonbulkyball to form snake-like structures. Buckyballs trap electrons, although they cant make electrons flow. Add sunlight to excite thepolymer, and the buckyballs will grab the electrons. Nanotubes, behaving like copper wires, will then be able to make the electrons or current flow. Ultracapacitors Mit uses nanotubes to improveultracapicator. The activated charcoal used in conventional ultracapacitors has many small hollow spaces of various size, which create together a large surface to store electric charge. But as charge is quantized into elementary charges, i.e. electrons, and each such elementary charge needs a minimum space, a significant fraction of the electrode surface is not available for storage because the hollow spaces are not compatible with the charges requirements. With a nanotube electrode the spaces may be tailored to size—few too large or too small—and consequently the capacity should be increased considerably Optical properties of carbon nanotubes Withinmaterial science, theoptical properties of carbon nanotubesrefer specifically to theabosorbtion,photoluminesence, andRaman spectroscopyofcarbon nanotubes. Spectroscopic methods offer the possibility of quick and non-destructive characterization of relatively large amounts ofcarbon nanotubes. There is a strong demand for such characterization from the industrial point of view: numerous parameters of thenanotube synthesiscan be changed, intentionally or unintentionally, to alter the nanotube quality. As shown below, optical absorption, photoluminescence and Raman spectroscopies allow quick and reliable characterization of this nanotube quality in terms of non-tubular carbon content, structure (chirality) of the produced nanotubes, and structural defects. Those features determine nearly any other properties such as optical, mechanical, and electrical properties. carbonnanotubesare unique one dimensional systems which can be envisioned as rolled single sheets ofgraphite(or more preciselygraphene). This rolling can be done at different angles and curvatures resulting in different nanotube properties. The diameter typically varies in the range 0.4-40nm (i.e. only ~100 times), but the length can vary ~10,000 times reaching 4cm. Thus the nanotubeaspect ratio, or the length-to-diameter ratio, can be as high as 28,000,000:1,which is unequalled by any other material. Consequently, all the properties of the carbon nanotubes relative to those of typical semiconductors are extremelyanisotropic(directionally dependent) and tunable. Whereas mechanical, electrical and electrochemical (superconductor) properties of the carbon nanotubes are well established and have immediateappplications, the practical use of optical properties is yet unclear. The aforementioned tunability of properties is potentially useful in opticsandphotonics. In particular, light-emitting diodes (LEDs)photo-dectors ased on a single nanotube have been produced in the lab. Their unique feature is not the efficiency, which is yet relatively low, but the narrow selectivity in the wavelenghtof emission and detection of light and the possibility of its fine tuning through the nanotube structure. In addition,bolometerand optoelectronic memorydevices have been realised on ensembles of single-walled carbon nanotubes.[2] Carbon nanotubes as a black body An idealblack bodyshould haveemissivityorabsorbanceof 1.0, which is difficult to attain in practice, especially in a wide spectra range. Vertically aligned forests of single-wall carbon nanotubes can have absorbances of 0.98-0.99 from thefar-ultraviolet(200nm) tofar-infrared(200ÃŽ ¼m) frequencies.Super black, a coating based on chemically etched nicle-phopsphoras alloy, is another material approaching the absorption of 1.0. These SWNT forests (buckypaper) were grown by the super-growth CVD method to about 10 ÃŽ ¼m height. Two factors could contribute to strong light absorption by these structures: (i) a distribution of CNT chiralities resulted in various bandgaps for individual CNTs. Thus a compound material was formed with broadband absorption. (ii) Light might be trapped in those forests due to multiple reflections Nanotubes As Space Elevators A space elevator would extend 22,000 miles above the Earth to a station, and then another 40,000 miles to a weighted structure for stability Scientists from Cambridge University have developed a light, flexible, and strong type of carbon nanotube material that may bring space elevators closer to reality. Motivated by a $4 million prize from NASA, the scientists found a way to combine multiple separate nanotubes together to form long strands. Until now, carbon nanotubes have been too brittle to be formed into such long pieces.[3] Conclusion Carbon nano tubes are very important material and are precious in day to day life , space research, nanotechnology , telecommunication , optics etc. However they are still not been used in their full extent because they are very expensive and are toxic in nature. We have to somehow find a cheap source of carbon nanotubes in the future.

The Effectiveness of a Multicultural and Bilingual Education Essay

The Effectiveness of a Multicultural and Bilingual Education 1 There is a lot of controversy concerning our public educational programs. Opinions and lifestyles differ; [-- often] Often what is beneficial for one group of people is counterproductive for another group. Educational issues are complex and sensitive; [-- therefore] Therefore, we must analyze both sides of the issue before we make a decision. Two controversial issues in today's public educational program are multicultural and bilingual education. 2 Some experts believe there are many benefits we, as Americans, can experience in a multicultural education. James A Banks states; "An education that reflects the experiences of a nation across its racial, gender and socioeconomic boundaries-benefits all students." (96) [This is from the book editor, not from Banks.] Banks is a professor and director of the Center for Multicultural Education at the University of Washington in Seattle. [Put this before the quotation.] He also believes that an important goal should be to educate students so they can participate successfully in the workforce and in their civic communities to help the nation actualize ideals such as justice, equality and freedom (Banks 97). Studies show that student participation and test scores are increased when taught with group-oriented strategies consistent with their community cultures. Research indicates [whose authority?] students from diverse ethnic backgrounds do better in school when they have a better un derstanding of each other?s cultures (Banks 99). 3 Gena Dagel Caponi associate professor of American Studies at the University of Texas in San Antonio states; "Studying any one part of us does not divide us, it educates us.

Mitsuyo Maeda :: essays research papers

Mitsuyo Maeda In 1904, "Judo's founder Jigoro Kano sent one of his strongest young judoka, Mitsuyo Maeda (1880-1941) with Jojiro Tomita to the White House to assist in a judo demonstration for President Teddy Roosevelt. After a formal demonstration, an American football player in the audience issued an impromptu challenge." The less adept Tomita took to the floor instead of Maeda. "Tomita failed with a throw and was pinned helplessly beneath the football player's bulk. Maeda, abashed by Tomita's poor showing and frantic to reassert the superiority of Kodokan Judo, stayed on. He persuaded some Japanese businessmen to stake him $1,000 in prize money and embarked on a long career of challenging all comers throughout North and South America. The 5'5'', 154-pound Maeda was said to have engaged in over 1,000 challenge matches, never once losing a judo-style competition and only once or twice suffering defeat as a professional wrestler. In Brazil, where he eventually settled he was feted a s Conte Comte ("Count Combat") and his savage system of fighting, now called 'Gracie Jujutsu,' is employed by certain fighters in present-day 'no-holds-barred' professional matches." 1 B I O G R A P H Y It was Maeda who brought Jiu-Jitsu to Brazil. As a member of the Kodokan, Maeda went to America with his kohai Satake, etc. as Judo ambassadors. He was said to have fought more than 100 fights and in Spanish-speaking countries in Latin America, he was respected as Count Koma (Conde Koma). Maeda was born in Aomori Prefecture in 1878. When he was a boy, he learned Tenshin (Tenshin Shin'yo) Jiu-Jitsu. He moved to Tokyo when he was about 18 and went to Tokyo Senmon School. He began practicing Judo and a record of him entering the Kodokan is dated 1897. He was very persistant and never gave up on anything. He was naturaly talented in judo and rose through the ranks quickly to establish himself as the most promising young judoka in the Kodokan. Maeda was a small man at 164 cm, 70 kilo. In 1904, he travelled to the U.S. with one of his instructors, Tsunejiro Tomita. The first and only place they demonstrated judo together was at the U.S. Army academy in West Point. Contrary to what has been published, they never went to the White House to meet the President, Teddy Roosevelt. It was the Kodokan great, Yoshitsugu Yamashita who taught Roosevelt judo at the White House and later engaged in a match with a wrestler nearly twice his size at Roosevelt's request, which took place at the U.

An Interview Of International Students Education Essay

In order to acquire more precise information and direct consequences, the research was conducted by two chief methodological analysiss, which are interview, and concentrate group. Interview is one of the most effectual and direct manner to analyze the premise made antecedently and compares the consequences with expected 1s. It is besides a manner for participant to acquire involved and speak about their positions and the interviewees are able to discourse their perceptual experience and reading in relation to a given state of affairs. Some argued the interview is non merely concentrated on roll uping informations about life: it is portion of life itself ; its human embeddedness is ineluctable ( Cohen, et al. , 2000 ) . As my research is focused on certain groups of people ‘s life behaviour, therefore interview would be the primary method to be used. Structured interview was considered at first as I thought it would hold more control of the interview and it could be easier to compare all the consequences. However, as the inquiries are instead unfastened, replies are really different from each and during the interview, interviewee would give some reply that may raise another valuable inquiry. The information interviewee are able provide is really more than I thought earlier and it may be better to merely utilize semi structured interview and allow it be more free and that manner I could besides acquire more meritable consequences. Although different inquiries might be used during questioning different pupils, all the inquiries are relevant to the chief research intent. Furthermore, the flexibleness of semi structured interview could overpower the restrictions on statistical analysis that would ensue. And flexibleness in planing and polishing the interview ushers and in put to deathing interviews is perchance the most important key to success in utilizing this method ( Horton, et Al, 2004 ) . Corbetta ( 2003 ) illustrate points like for semi structured interview, within each subject, the interviewer is free to do the conversation as he thinks tantrum, to inquire the inquiries he finds appropriated in the words he considers best, to explicate the inquiries and inquire for elucidation if the reply is non clear and to make his ain manner of conversation. In semi structured interview, a specific hypothesis does non necessitate to be tested needfully by the interviewer ( David & A ; Sutton, 2004 ) . Because the research is seeking to happen out a consequence instead than to turn out a hypothesis, it may be better to follow this type of interview. Ten International pupils from different states were interviewed meanwhile five Chinese pupil were interviewed every bit good. The 15 interviewees claimed they all drink before the interviews officially start. In order to make a relaxed and private ambiance, all the interviews took topographic point in interviewees ‘ room and all of interviewees have their single room in No.11th edifice ( international pupils ‘ abode, No. 12th Building ( postgraduate pupils ‘ abode ) and No. 16th edifice ( Male pupils abode ) . Due to the turning away of mistranslation between Chinese and English, the interviews were conducted wholly in English and the replies were recorded by handwriting drumhead in English every bit good. Some inquiries were added after a few interview were done as comparing the replies between some Chinese pupil interviewees gave and some international pupil interviewees, there will be valuable inquiries emerged. And that could be seen as countries I did non expec t. Semi structured interview gives me chances to examine for thoughts and sentiments of the interviewee. Probing is understood as a manner for the interview to research new waies which were non ab initio thought ( Gray, 2004, p.217 ) . Besides cardinal subjects and sub-questions from interviewee give research worker a sense of order to make inquiries from unplanned brushs ( David & A ; Sutton, 2004, p.87 ) . For illustration, one inquiry was which manner of imbibing do you prefer: the typical Chinese pupil manner of imbibing ( i.e. purchase a bottle and blend it with soft drinks and portion it ) or typical Western pupil manner of imbibing ( i.e. everyone purchase their ain drink ) and why. Most of Chinese pupil and international pupil interviewee answered sooner typical Chinese pupil manner ; nevertheless Chinese pupil interviewee besides claimed they think international pupil by and large would non prefer the typical Chinese pupil manner of imbibing. Consequently a inquiry for inte rnational pupil interviewee â€Å" why do you believe some Chinese pupil claim they think international pupil would non prefer the typical Chinese pupil manner of imbibing † is add up. Furthermore, with the purpose of acquiring more in depth consequences, the model of focal point group were used as 2nd method. A focal point group is a structured group interview. It is an exploratory technique that sets out to happen a scope of sentiments about a peculiar subject ( Hawe et.al. , 1990 ) . Focus groups are particularly effectual for capturing information about societal norms and assortment of sentiment or positions within a population. The population of this research would be two peculiar group- international and Chinese pupils in UNNC. Denzin and Lincoln ( 1994, p.365 ) demonstrate that the term â€Å" concentrate group † could be used to a state of affairs in which the interviewer ask group members really specific inquiries about a subject after comparatively big research has already been completed. Because non everyone will hold the same positions and experiences and due to different in age, gender, entree to resources, and other factors-many different point of view will probably be expressed by participants. Within a survey, focal point groups are typically one method among many that are used to make a complete image of how given issue affects a community of people. Focus groups contributes to this wide apprehension by supplying reasoned informations on societal and cultural norms, the pervasiveness of these norms within the community, and people ‘s sentiment about their ain values. Denzin and Lincoln ( 1994, p.365 ) demonstrate that the term â€Å" concentrate group † could be used to a state of affairs in which the interviewer ask group members really specific inquiries about a subject after comparatively big research has already been completed. Because semi-structured interview had already been done at earlier phase and I want to happen out wider and more in de epness consequence, two focal point groups was formed, and participant were indiscriminately selected, and participants are wholly different from those who took portion in the interview. Harmonizing to Merton et Al, the size of the group should seemingly be determined by tow considerations: it should non be excessively big to manage and non to be excessively little it fails to supply better coverage that an interview with one person. Nevertheless, the figure of participants besides depends on the aims of the research ( Stewart & A ; Shamdasani, 1990 ) . Smaller groups including four to six people can be preferred when the participants have a great trade to portion the subject or hold had adequate experience with the subject that is traveling to be discussed ( Kreuger, 1988, p. 94 ) . Because of deficient clip and I am seeking to cut down cost, besides international pupils and Chinese pupils are both familiar with the research subject and they have their enthusiasm replying the inqui ries, each group consists of five members, of whom the first group with international pupils discusses four inquiries, the 2nd group with all Chinese pupils discoursing the same inquiries. Furthermore, a focal point group should be carefully planned treatment designed to ask perceptual experiences in a defined country of involvement in a permissive, non-threatening environment ( Kreuger, 1988, p. 18 ) . All the inquiries were pre planed and under the way of non being insistent as interview inquiries and the first group treatment took topographic point in a kitchen of international pupils abode, where is regarded like a common room for international pupils and the topographic point they have drinks and socialise. This manner all the participants may experience less intense and more permissive. To do certain the 2nd group participants have a relaxed atmosphere every bit good, the treatment occurred in the juice saloon, a topographic point where Chinese pupils ever like to socialise, l oosen up and holding treatment at that place. The process of the treatments were recorded by tape recording equipment and summarized in word paperss. Ethical motives: Ethical jobs and concerns are portion of mundane pattern of making all sorts of research, particularly in qualitative research. It is argued there are at least two major dimensions of moralss in qualitative research ( Guillemin & A ; Gillam, 2004 ) . The first 1 is â€Å" procedural moralss † that usually involves seeking blessing from a relevant moralss commission to set about research affecting worlds. The 2nd one is â€Å" moralss in pattern † that ethical issues originate in making the research. About the utility in turn toing ethical issues that originate in pattern, professional ethic codifications may be non practical and applicable but merely serve as general guidelines ( Guillemin & A ; Gillam, 2004 ) . Procedural moralss of my research would be evaluated. There are some countries in which ethical jobs face the judge such as keep backing the nature of the rating research from the participant, exposing participants to Acts of the Apostless that would harm them ; invasion of participant ‘s privateness and keep backing benefits from participant and so on ( House, 1993 ) . As for my research, ethic would be examined from the facets of informed consent, confidentiality and privateness. Informed consent in qualitative research is frequently consider unsafe as it indicate that the research worker knows before the event that what it will be in the terminal and its possible effects, nevertheless this is non the instance in qualitative research ( Eisner, 1991 ) . Although as my research is qualitative, I am non able to state the participants what the consequences would be and what effects it would convey, I did informed and explained all the participants the nature of the probe before the interview and concentrate group was initiated. Piccolo & A ; Thomas ( 2008 ) illustrated that the topic should show his/her credence of digesting fraudulence and incommodiousness and the research worker must vouch the safe calabash of confidentiality and the public assistance of the participant. Capable must be made feel that they could discontinue the survey at any clip without any penalty and reverberation. In my instance, all the participants were asked whether if they are willing t o reply the inquiries of their imbibing behaviour and besides give information about their parents ‘ imbibing behaviour as there are inquiries related in the interview. Additionally, they were informed if they feel uncomfortable replying some inquiries they could merely decline to reply it or discontinue the interview or treatment at any minute. Qualitative judges could ever cover with confidentiality by trying procedure and through proficient precautions when the information is analyzed ( Shaw, 2003 ) . The United States National Institution of Heath grants certifications of confidentiality for some probe incorporate private information that may take to stigmatisation or favoritism, information related to utilize of intoxicant, drugs or other habit-forming substances is one of them. Because my research is linked with the use of intoxicant, confidentiality is needed without any uncertainty. In order to do informations drumhead easier, I had asked all of the participants ‘ full name, age and nationality. Their information along with interview responds transcript is traveling to be destroyed after informations analysis is done. The record tape and the paperss that have all the information in would be destroyed and deleted. Interviewees and participants were told their information would be vanished after the research is d one and they gave their information voluntarily. Furthermore, I chose to hold the interviews and concentrate group in participants ain room protected participants ‘ privateness as they were speaking their ain behaviour. Restrictions The restrictions of this survey Begin with me, as a research worker. I am restricted with timing, deficiency of certain cognition and entree. Basically, being an undergraduate pupil, non-professional and missing in assurance due to this being the first research survey could impact what I have to show. One restriction of my research could be related to reflexiveness as semi structured interview is one of the method I used in the research. The interview has been important for deconstructing the production of cognition within research, taking to concerns over how we understand another individual ‘s â€Å" universe position † , however, when it comes to concerns over method or analysis within the academy, reflexiveness is frequently limited to either an analysis of the kineticss between the interviewer and the interviewee or warning of biased caused by temperament of the research worker ( Briggs, 2002 ) . As mentioned earlier, there were some inquiry of the interview were added and modified after a few interview as done, responds of some early interviewee have effects on the coevals of the inquiry. Their replies changed my perceptual experience of some certain country before planing the inquiries and I have to alter and add inquiries in the terminal to acquire more accura te and specific informations. Furthermore, being a Chinese pupil making interview that contains inquiries about other people ‘s position of Chinese pupils ‘ imbibing behaviour, interviewee sometimes may believe twice before replying some inquiries and being conservative non give all the responds they want because my nationality is impacting them. Besides there might be some grade of demand features existed during the interview. A demand characteristicA refers to an experimental artefact where participants form an reading of the experiment ‘s intent and unconsciously change their behaviour consequently. There are some of the inquiry of the interview could be misdirecting the interviewee give replies they anticipant the interviewer would desire. For illustration inquiry No. 17 assumed Chinese pupil would travel to the ideal pupil saloon on a regular basis, this may give them the incorrect thought I want the reply that there would be more interaction between Chinese a nd international pupils if there was of all time a ideal pupil saloon. Other restrictions could non be neglected every bit good. Due to the ground this is my first research, I am a comparatively inexperient interviewer, which may ensue non able to inquire prompt inquiries and some relevant informations might non be gathered. With the method of semi structured interview itself, non merely the informations could be inaccurate, but besides it could hold undependable informations as it is non-standardized and different inquiries were asked for the interview. And the cogency could be questionable as I am non able to happen out if the respondents were lying. Furthermore, sample of my research could be excessively little as I merely interviewed 15 interviewees and the figure of Chinese pupil participants and international pupils participants were non the same, this could make colored consequences. Meanwhile, the usage of focal point group may hold similar defects. Datas could be undependable and cogency should be argued every bit good as the little figure of r espondents bounds generalisation to the wider population. Besides during the procedure of making focal point group interview, there was a group member of international pupils ‘ group being over strong and dominant of the treatment which could do colored consequences.

Caase study

The two primary functions of Varian Magna Agricultural Cooperative Society (EVANS) are procurement of agricultural produce from the farmers & marketing it to the amandine, and procurement & supply of agricultural inputs to the farmers. The objective is to devise a strategy for EVANS for efficient use of funds with respect to procurement and sale. Criteria Benefit of the farmers should be the top priority while planning the strategy.Financial planning must be done carefully in view of the limited supply of funds. Variation of prices of payday as well as fertilizers during different seasons must be used to the advantage of EVANS. Since the society shares a good relationship with the bank, this must be leveraged to suit required credit facilities. Options We assume that EVANS maintains minimal liquid cash to handle administrative expenses and interest.Some of the relevant options are listed below: Option 1: Option 2: Option 3: Evaluation Option 1 Farmers get sufficient funds to plan lon g term Losing out on higher margins by selling payday at current price Cost benefit on early arches of fertilizers is marginal Initial cash balance Cash paid to farmers Revenue from payday sales +500000 Fertilizers purchase expense Overheads -35000 ODD Extension Option 2 Cost benefit by postponing payday sales is high Insurance for payday -10000 From reserves Option 3 Farmers get their part of their share on time Cost benefit on early purchase of fertilizers can also be leveraged Credit limit extension translates to higher interest Part payment to farmers -250000 -38000 -298000 Interest -15000 Decision The high cost of storage, labor and equipment and the low savings margin make the early purchase of fertilizers an unattractive option.On the other hand, there would be a significant loss with regard to opportunity cost since we are selling payday at the current price of INNER 5000 per ton. Moreover, a marginal extension of Overdraft limit is required to support operations. The higher margin on payday sales can be leveraged by holding the stock in storage for 6 months. The high overheads of storing fertilizers can be avoided. Since we have sufficient reserves, we can support daily operations with minimal funds. The objective of the Co-operative society is to benefit the farmers over the long run. If the members agree to give up part payment towards procuring fertilizers at the discounted price, they can get the coupled benefits of the higher margins on payday and reduced fertilizer costs. Therefore, we recommend option 3.Action Based on the calculations below, accounting for minimum and maximum possible price of payday in 6 months, we can bring about a substantial reduction in cost per bag of fertilizers. Min Max 630000 750000 Profit margin 130000 250000 (-) Interest Net profit from payday sales 210000 Fertilizer cost 475000 38000 Total Cost 513000 (-) Net profit from payday sales Revised Total Cost of Fertilizers 423000 303000 Revised cost per bag of Fertilizer s 222. 63 159. 47 Contingency Since our recommended option requires deferring part payment, the farmers do not receive the entire sale revenue right away. This option also requires the bank to allow an extended overdraft limit to EVANS. In the circumstance, that either or both parties are unwilling to accept this proposal, we recommend option 2 as a backup.

Prejudice †Montan 1948 & Snow Falling on Cedars Essay

The conventions of the concept, ‘prejudice and hatred are never right in a just society’ are explored in Larry Watson’s 1993 fictional novel, ‘Montana 1948’ and also in the film, ‘Snow Falling on Cedars’, directed by Scott Hicks. Specifically, the two compositions delve into this notion by mainly focusing on the prejudices that are placed on those who are not of the Caucasian race. For example, in ‘Montana 1948’ the Indians are discriminated against and American-Japanese citizens are victimized in ‘Snow Falling on Cedars’. These prejudices are similarly portrayed in both texts; however there are also some contrasting features. Varying techniques such as changing from present to past text to emphasise the continuous use of memory, various panning shots and most importantly, dialogue, are all used to convey that prejudice and hatred are never right in a just society. In ‘Montana 1948’, written by Larry Watson, we are instantly introduced to David, the narrator of the story. David immediately reveals that the story will be told as a memory; he establishes this in the first sentence of the prologue, â€Å"From the summer of my twelfth year I carry a series of images more vivid and lasting than any others of my boyhood and indelible beyond all attempts the years make to erase or fade them†. This is written in past tense which instantly shows the audience that story is a memory of David’s. The sentence also creates an element of mystery as David mentions he has attempted to forget the summer of his twelfth year. After instantaneously establishing the importance of memory in this novel, Watson then begins to weave racial prejudices which are the other key feature in the composition. â€Å"A young Sioux woman lies on a bed†¦Ã¢â‚¬  is the second sentence of the prologue and by using the word ‘Sioux’ makes the audience aware of the underlying racial issues about to become apparent. As the story continues, we are made aware. We find that the story is set in a small community, Bedrock, which has a nearby reservation filled with Sioux Native Americans. The story is set in 1948 and is told from David’s perspective; however this constantly changes from present to past tense, which emphasises that the composition is a memory. With this fluid, constant conversion, the story is given more depth and the audience is provided with more information to truly understand every aspect of the focal story. Language used in the text; mainly colloquial within the characters’ dialogue portray the issues of prejudice. We are given the impression that David likes the Indians and thinks of them as equals; especially since David talks of his love for Marie and his fondness of Ollie. However, not everybody feels this way. **We are also made aware of the Indians status within society due to the language and dialogue used throughout the text. â€Å"My father did not like Indians†, â€Å"We want them white† and â€Å"little squaw† highlight such language conventions.
