Statistical Problems - Essay Example The approximation becomes better with increasing sample size The simple random sample of 50 women with one job is greater than 30. Therefore, in this case Central Limit Theorem is applicable and the distribution of the sample can be assumed as normally distributed. (b) The percentage of all samples of 50 women with one job that have the mean length of time employed within 20 weeks of the population mean is (approximately) equal to the area under the normal curve with parameters  µ and 13.01 that lies between  µ - 20 and  µ + 20. The corresponding z-scores are: (c) No. If I bought one bag of water-softener salt and it weighed 39 lb, I would not consider this evidence that company’s claim is incorrect. Because there is 25.14% probability that the weight of one randomly selected bag of water softener salt will be 39lb or less. (d) Yes. If I bought 10 bag of water-softener salt and it mean weight was 39 lb, I would consider this evidence that company’s claim is incorrect. Because there is only 1.74% probability that the mean weight of 10 randomly selected bag of water softener salt will be 39lb or

Explain and discuss how Globalisation has affected the growth of Essay

Explain and discuss how Globalisation has affected the growth of international business - Essay Example In any case, it has been proved that globalisation can highly affect the growth of international business but the process used for the achievement of this target is not standardized. The involvement of globalisation in the growth of international business has been highlighted in the literature and the empirical research; however, academic researchers have employed in order to justify the power of globalisation on international business. In accordance with Dunning (1999), globalisation offers to businesses the chance to expand their activities in the global market, either physically or through the Internet. Reference is made, for example, to the case of the communications industry where globalisation has given ‘enormous opportunities for expansion and high profits for the industry’s major firms’ (Dunning 141). Another example used in the study of Dunning for showing the relationship between globalisation and international business is that of the financial services firm Merrill Lynch, a firm ‘operating in about 31 countries’ (Dunning 141). In accordance with the view of Dunning, as presented above, globalisation can support the development of businesses internationally; however, such benefit is expected to be available only to large firms, which have the resources necessary for enjoying the benefits of globalisation. Small and medium sizes firms would face many difficulties in entering the global market; moreover, the firms of this size could not compete international firms. In other words, globalisation could support the growth of businesses internationally, but such prospects would involve mostly in firms of large size – as also explained in the study of Dunning (1999) above. A different perspective of globalisation is highlighted in the study of Worthington & Britton (2009); in accordance with the above study, the international market is not related only to international businesses; it is suggested that ‘businesses of all sizes should be aware of their international context’ (Worthington & Britton 45). Moreover, it is made clear that one of the key benefits that globalisation can offer to businesses internationally is the provision of an extended market for their products/ services. In other words, for the above researcher, the concept of globalisation reflects the existence of a market, which is geographically expanded as possible – covering the markets of all countries worldwide. In the study of Wall and Minocha (2009) emphasis is given on the use of globalisation for achieving benefits in a wide area of activities/ areas, including trade, politics and sociology. Regarding specifically trade, globalization is expected to have specific benefits: improvement of the quality and the level of trade developed among states and organizations internationally (Wall & Minocha 2009); moreover, globalisation could help toward the ‘increase of the international capital flows’ ( Wall and Minocha 2009, p. 14). Also, globalization could help towards the increase of ‘capital flows worldwide’ It is expected that businesses, which operate globally, would be also strongly benefited from globalisation. However, an important implication of the view of Wall & Minocha (2009) on globalisation would be the following one: not all firms of large size are able to compete their rivals; the lack of effective management would not allow firms of small/ medium size to get access to the international

Nanoprobes used to Fight Breast Cancer Tumors Essay

Nanoprobes used to Fight Breast Cancer Tumors - Essay Example The prevalence rates are quite similar throughout the world with the United States leading in the number of incidences and China showing the least. Historically, Eastern Europe and the Far East have had low rates of breast cancer which however, have begun to rise rapidly (Babb et al, 2001). The age related incidence is also very significant in this disease as, the age group most at risk are women over 50 years old (80% of cases) and the highest number of cases is in this 50-69 age group (Office for National Statistics, London, 2008). The treatment for breast cancer is dependent on various factors like, the type of breast cancer, the size and histopathology of the tumor, the stage of the disease and the presence or absence of certain biomarkers. The general health of the patient is also a major factor in determining the mode of treatment. The options range from unilateral to bilateral mastectomies, lumpectomy, with additional chemotherapy or radiation therapy or chemotherapy and radiation on their own. Tamoxifen, an endocrine targeting drug which acts by interfering with the activity of estrogen, a female hormone is the largest selling drug for breast cancer. Tamoxifen has been used for more than 30 years to treat breast cancer in women and this too, has side effects that cannot be overlooked and in most cases is usually an additional therapeutic drug. All these treatments are painful in different degrees both physically and emotionally. The recovery time is long, especially in older patients and the nature of th e disease, that it could reoccur, is an emotionally exhausting variable to live with. The invasive and painful features of the currently available treatment options and the high incidences, makes this a very important disease in which to fund research. The awareness, on the rising numbers and the need to address the methods of diagnosis and treatment has been heeded by many countries and organizations. Technological advances in one area serendipitously affect applications in other areas. Nanotechnology is one such science that has influenced developments in many spheres of science, technology and medicine. Nanotechnology involves the creation of practical substances, devices, and systems which can be used in different applications on an incredibly small scale. The size and scale we are referring to here is in nanometers and hence the name nanotechnology. Nanotechnology works between 1 and 100 nanometers, a nanometer being, one billionth of a meter. To put this in proportion we can compare this to being the same as about ten times the diameter of a hydrogen atom. Advances in this technology have had applications in treatment options for many diseases including cancer. Introduction Significance of the Issue Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in women (http://www.cancer.gov/statistics/). Breast cancer incidences and statistics are calculated and processed by gender, age, geographic variation, trends over time and prevalence. Breast cancer is the most common cancer in the United Kingdom although the incidence in men is minute compared to other cancers. In 2005 there were 45,947 new cases of breast cancer that were diagnosed, of these 45,660 (over 99%) were in women and 287 (less than 1%) in men. As mentioned earlier the lifetime risk of being diagnosed with

Online Discussion for Accounting class Essay Example | Topics and Well Written Essays - 250 words

Online Discussion for Accounting class - Essay Example The financial performance of a company can be analyzed either using single date statements or by comparing the performance across time. The four financial statements are the income statement, balance sheet, statement of retained earnings, and statement of cash flow (Weygandt, Kieso, Kimmel, 2002). These statements provide a summary of the financial performance of a company during a financial period. The balance sheet shows the position of the company at a specific point in time. The use of ratio analysis is one of the best ways to evaluate the performance of a company during a period. Another methodology to assess the performance of a company is by using comparative statements. Two financial techniques that can be used to compare financial statements are vertical and horizontal analysis. I think that techniques that compare performance across time are more effective because they show trends in financial performance. Companies that have rising performance across time are more desirabl e than firms that have declining

MOZARTS REQUIEM Term Paper Example | Topics and Well Written Essays - 1500 words

MOZARTS REQUIEM - Term Paper Example He started composing music from the age of five and also played before the royalty. He travelled widely, with a penchant for performing. He had also performed before the European royalty at a very early age. There was always a search for a better position, leading him to change places and compos with a lot of regularity. While on a visit to Vienna in the year 1781, he faced dismissal from the position at Salzburg. He stayed on at Vienna, but the financial security was much lesser. The final years in Vienna were extremely productive, with the composition of a number of pieces. The part that we would concentrate on is the Requiem. It was one of his most important works, but was left in an unfinished state for most part. The situation that led to his death has been a subject of folklore, with a number of interpretations doing the rounds. Mozart learned the art from a lot of the other musicians, with the compositions straddling both worlds. Some of the compositions are very light in the constitution, while some of the others are extremely dark. The body of his work is very elaborate, with over six hundred pieces, and many of them have been taken as the best in symphony, concert ante and other forms of music. He had been an inspiration to some of the other leading lights, including Beethoven; who was inspired by him. He was the youngest one among seven, children; five of whom had died in infancy. His father, Leopold Mozart was a minor composer in the court of the Count of Salzburg. It can be noted that Leopold was a devoted teacher to his son, the young Mozart. It can be also said, that Mozart wanted to progress beyond the teaching given by his father. Alongside conventional music, he also taught Mozart academic subjects. He and his sister were considered to be child prodigies. All of the concerts began with the concerts at Munich, going on to the courts of Vienna and Prague. The tour lasted for almost three and a half years, ending through the cities of Zurich. Moz art was influenced by a number of composers during that period. Some of the most famous names include the individuals like Bach. The trips of the family were often done in the conditions, which were not conducive for travel. In the year 1769, Mozart and his father again left for travel, which took them through many places. They finished the travel by the year 1771. Leopold, his father had hoped for some kind of appointment in the courts of Italy, but it never materialized. In the year 1777, Mozart resigned from the position at Salzburg, and went in to travel in different parts of Europe like Munich and Paris. Mozart fell ill in the year 1791 during the premier of an opera, which was written as a part of the responsibilities for the emperor’s coronation. But, he kept on performing most of the functions, and also had the premiere of the play. The deterioration of health became more evident on the 20th November of same year, making him bedridden. He started to suffer from pain, vomiting and swelling in the joints. Mozart was looked after in the final times by his wife and her sister. He was also attended by the family doctor Thomas Franz Closset. During that period, he was occupied with the creation of Requiem, which was the last of his seminal works. This is one of the reasons, why it has been chosen for writing this paper. THE REQUIEM The Requiem written by Mozart was one of the finest works by the composer. The fact that it was written during the final years of his life, further makes it more important. It was left in an unfinished state by the composer, and was finished after the death of the composer on December 5. The completed copy was sent to Count

Vodafone Group PLC - Essay Example We will use the same conduct fundamental analysis of the company to assess whether the stock is likely to increase or decrease in value in the short- and long-term and whether the stocks current price is an accurate reflection of its value (Street.com, Inc.,2007) Revenues exhibited growths within the range of 10% to 33% for the last five year period except for the decline from 2004 to2005 by 21%. Despite the decline in 2005 from 2004, gross margins were noticeably high from 29% for the years 2003 and 2004 respectively and still high at 22% and 21% respectively for the years 2005 and 2006 respectively. This means that decline in company revenues for a given year which could have been an indication of lower output did not cause the company to suffer the decline in terms of productivity or efficiency since the gross margins were still high, although the decline was still felt since the gross margin from2004 to 2005 also declined from 29% to 22%. The apparent decline in mark up due to decline in revenues from 2004 to 2005 was remarkably offset by the increase in bet profit margin relative to the years where changes were noted. The lower gross margin for the year 2006 and 2006 as against 2004 and 2003 did not necessarily resulted to lower net profit margin for the corresponding years under study, since net profit margin for the years 2006 and 2005 stood at both similar rates of 22% which were surprisingly higher than for 2004 and 2003 respectively. This difference in the results could only mean better efficiency for the years 2006 and 2005 over the year 2004 and 2003. Viewed from perspective of improving management performance in terms of efficiency, the management has indeed shown resiliency and disciple for the latter years as compared against the earlier years. This is however not to lose the remarkable achievement net profit margin 1n 2002 which got reflected at 69%. What clearly showed an increasing trend without sign of going down are the

Martin Bernal and describes Essay Example for Free

Martin Bernal and describes Essay Black Athena is the works of Martin Bernal and describes the Afro-asiatic roots of classical civilization in ancient Greece. Martin examines the perception of ancient Greece in relation to its African and Asiatic neighbours especially in West Europe. This occurred in the 18th century onwards and exhibits the denial by the western academia and the influence of the Greek culture on civilization. In his work Bernin does not support the Greek civilization as being founded by the Aryan settlers whose trace is Europe. He gives proves as to the arguments of the famous great Grecian thinkers like Plato, Socrates and Aristotle that Phoenician civilization originally colonized Greece. In this basis he comes up with a theory based on the methodology of these historians and this theory states that Greece was colonized by northern invaders with their existing colony established in Phoenicia. (Moore, 2001) He uses several examples to explain that countries of Africa like Egypt and those on the west are being admired by prominent European leaders because of their historical backgrounds. The current Greek language spoken in classical Grecian world has its roots in the proto Greek language and influence from other Anatolian languages that were spoken nearby. The culture in Greece is believed to have been developed as a result of comparison of unity of elements. Bernam puts great emphasis on the elements of Africa that shaped the Grecian history. He compares the 19th and 20th century eurocentrism with the development of the western appropriation culture and its development. He argues that the western world influenced the Modern Greek language terming the contact between the indo European languages and the culturally influenced Egyptian and Semitic languages as very key in the determination of the modern Grecian culture and language. He gives examples of some words being used in the modern language of Greece to have been from these origins. He estimates the introduction of the Greek alphabet to have been between the period 1800 and 1400 BC. (Moore, 2001) Bernal came to the conclusion that the relationship between ancient Greek and Egyptian influence should not be taken lightly. His background traces to the interests he had on Egypt since childhood and the inspirations by his father. He is further encouraged to take this direction by the discovery of the works of Cyrus Gordon and Astour. Afrocentrism which is now the most felt model in the North American primary and secondary schools has been noted to be the most significant and challenging developments in higher education systems and curriculums. It’s a model which encompasses both multi cultural and Afro Hellenic orientations. This simply means that it’s grounded in ethnic and cultural diversity and the aspect that it is attributed to Africa. In contrast with the black Athena which attributes the development of modern Greece to the western world, the Afrocentric model attributes it to be an abstract, intellectual civilization which is grounded in the traditional orientations of western civilization. Bernal’s discovery of the black Athena is the modern thinking of how the Greek world came into being but has been criticized as not with definite reasons as afrocentric movement. His was of a different order that racist and anti Semitic scholars only showed the historical facts from the Bronze Age onwards making the culture of Greece to be a product of only Egyptians and Levantines. He argues that for the complete concealing of the origin of the Greek culture we need to consider the north of Athens and the medditerenian island of Crete, civilizations which took place in the third millennium. Bernal’s case is different from the afrocentric models because it rests upon on legend and myth. It relies upon the stories told by the ancient Greeks like Aristotle and Aristotle. He interprets these stories as the memories of the Egyptian and Phoenician developments. There is a critic about this however because we need to ask ourselves ‘of what benefit is myths and legends? ’ (Bernal, 1987) Bernal attributes archaeology, myth and linguistic borrowings as evidence to the development in Greece. The history and development of Greece is of much importance to the culture adopted today in Greece. Without the historical base Bernal suggests that tracing of the Greek history and civilization would be very complicated. Bernal claims that approximately 30% of Greek is of Semitic origin, 20% from Egyptian origin and the rest from the ancient Greek origin. Critics however have suggested that his demonstrations is only based on the resemblance merely and not the principles of linguistic adaptation. Bernal takes the similarity of a few words and tries to generalize. The afro centric orientation is based on the western world and argues that linguistic development in Greek civilization has been natural like the development of any other language. (Bernal, 1987) The contention that the Egyptians were the greatest civilization in history is critically opposed by the Afrocentrists. Afrocentrists view the Egyptians as only blacks who cannot contribute anything to the civilizations which took place especially in Greece. Bernal regarded the developments of Greeks like the scientific and mathematical orientations as very important movements. It’s however criticized by the afrocentrics as a total disregard of the facts of chronology. Conclusion The black Athena and the afrocentric movements have had an influence to the history and civilizations of the current Grecian histories. In our study of the two models we need to understand the fact that the current ancient civilization is as a result of amalgamation of the two models. Bernal in his book Black Athena: The afroasiantic roots of Classical civilization addresses the issues which have made the Greek world today be the way it is. Reference: Bernal, M. (1987) Black Athena: Afroasiantic roots of Classical Civilization, Rutgers University press. Moore, D. (2001) Black Athena writes back, Duke University press.
