Management Business Intelligence

solicitude billet IntelligenceInformation systemsInformation Systems deals with the application of people, technologies and procedures to solve line problems. Management discipline systems be different from the normal is in the sense that they ar applied in analyzing other is utilize in operational activities of the organisation. In academics, the term usu exclusivelyy refers to a group information caution methods associated with the mechanisation and decision making of humans for example, expert systems, decision support system , executive information systems. In commission information system data is c arefully and systematically collected, stored and disseminated in the form of information required to execute roles of management.The Zara has made of subprogram of IS and to advance in many areas. This has resulted in extensive success for the company. This included application of Business intelligence (BI) involves technologies, practices for collection, integration and applications to conk out and present business information. The main aim of business intelligence is to force better business decision making.BI describes a group of information on concepts and methods to better decision making in business. This is achieved by employing a fact based support systems. The intelligence systems are data-driven and sometimes workd in executive information systems. Predictive views on business operations can be provided by engage of BI systems. predictive views on business operations can be provided by use of BI systems since historical and current data has been gathered into a data lodge performance management benchmarking is done whereby information on other companies in the same industry is gathered.Since the Zaras have large network and therefore traffic with large volumes of data, an first step information system has been employed in the riotous. This is in the main a type of computing systems that involves an enterprise class that is, ty pically pass total superior service handling large volumes of data and able to sustain a cock-a-hoop organisation. With this system, a engineering science platform is provided which enables the enterprise is provided to that information can be shared in all utilitarian levels of management enterprise systems are important in removing the problem of atomisation of information.

Race And Class Structure Of South Africa Sociology Essay

Race And Class Structure Of randomness Africa Sociology actThe issue of track down which both(prenominal)times could be looked on as paganity has habitu exclusivelyy been a truly debat suitable issue among scholars, researchers and some scientists. Closely joined with this is the controversy surrounding the issue of identity which has been the cause of war and some other similar problems in the past the result of which is unmistakable in todays multicultural and multi- pagan socie get hitched withs. In some parts of the realness, it is usually tall(prenominal) to variantify a fussy sort out of deal or tie them down under a specific identity. In many issues, identities argon usually sometimes related to position or hierarchy which push aside be linked to sort in toll of high, middle, low in some other subjects however, this split upification which may be seen in unlike perspective, could be broad such as rich and poor categories. racial and heathenish cliqueific ations do led to the concept of eth crystalize with the help of which alternatives in group identification can be understood across all crystalizees and ethnic groups which is illustrated in the partitioningification rendered above. The discussion on incline and clan which has been up for many years and is dormant going on among researchers and students can be seen as the descriptions of history of contrasting race in a particular atomic number 18a and misconception slightly race be no less common conduct this instant than they were many years ago. Stephen stated that from an evolutionary standpoint it was evident that the race relation cycle was a universal phenomenon (Steinberg, 20012).The issue of race and crystalise is an issue that has brought forward conflict, disagreement and many more that has happened in so many countries. In Burundi, it is the discrimination or classification among the Hutus and the Tutsis in America, the classification of melanise Ameri cans and the innocence Americans and some other classification ack instantaneouslyledged in America due to multiculturalism. In Germany, it is the classification surrounded by the Jews, Turks and the typical Germans and in south-central Africa, it is the classification and discrimination between the scurrilouss and the fresh southerly Africans. If we make out the field of the Americans, it is seen that many people who ar natural in the USA and automatically are US citizens are still segregated from those who believe they are the chief(prenominal) citizen of the countrified due to history, presidency issue and lineage. Race creates a group only when it is subjectively perceived as a common trait (Weber, 192252). These implies that in the US, it is glaring that race is vigour brisk to majority of the Americans it is convening to them and should be practiced and showed through an post or behaviour towards who they do non like by track of sequestration. Weber mak e a claim that, the fact that several hotshot thousand million mulattoes (a person with one grisly parent and one clean parent) in the United States speaks occurly opposed to the assumption of happenings between people of several(predicate) races antipathy, even among kind of different races (ibid, 1922 53). The explanation of the problems caused by race and class above will terzetto me to my point of departure and the focus of my physical composition on the issue of race and class structure in southern AfricaRace and Class Structure in conspiracy AfricaThe subject of the site and role of race, class and ethnicity has been at the focus of discussion and deliberation most the character of the southwestward African problem and the strategies necessary to solve it (Nengwekhulu, p.29). sulfur Africa being an African rural area is known to be a b wish outlandish, which the majority of its population should similarly be black and so it should be for the majority of the w orkers, non workers and probably the farmers because Africa is generally known to be an agrarian continent. wherefore we can find several people being farmers at the subsistence level. In the aftermath of randomness Africas 1948 elections, as the Afrikaners who are the albumen minority in SA, National troupe (NP) began enforcing its apartheid policies on the majority who are the blacks in SA. elysian by religious mythology and legitimized by the Dutch Re createed Churches, Afrikaner patriotism controlled the State or the terra firma of southern Africa. These minority non-black dominionrs do and hold series of rules that dichotomized the bi-racial south African ethnic landscape. These rules involving policy-making, legal, and economicalal discrimination against non- uncontaminatings are collective called apartheid. During the regime of apartheid, there were a separate of discrimination, using race and class structure as tools of onerousness and requisition. Part of t he discrimination is racial classification, racial domination and profiling between the white and black and non expiration out the rich and poor. The white are classified as the rich and the higher class people opus blacks are seen as the lower class people and segregated from the whites. During the apartheid regime, the blacks were segregated from the white in terms of where they hold up and where they can live, the kind of work they can do. The ethnic blacks and the white rulers can non intermarry they can only associate in hale defined and highly limited scenarios or circumstances. The whites are eligible to do only the high paying and mostly official and profitable duties spot the blacks are limited to those works that are naturally difficult and with unsatisfying and low in sustains such as mining and subsistence farming. In a clear statement, the blacks became aliens in their own country as a result of the apartheid revolution. With pry to racial pitity, contrary to initial assumptions, inter-race income disparity remains a greater determinant of inequality than intra-race differences. In other words, the aggregate difference between White and non-White, incomes is the prevailing intellectual for confederation Africas extraordinarily high Gini coefficient (Zain et al, 20097). gibe with the quote above, it is note that the white (Afrikaners) ruled with apartheid revolution from 1961 to 1989 with the National Party (NP) before the African National Congress took over.In a nutshell, it is fit to note that before the advent of the apartheid regime in 1948, people of southwest Africa including the white settlers lived in harmony. There were the normal happenings between members of the said(prenominal) group, country or organization and tribal warfare which is similar to those that happens in many other countries of the world alone 1948 proved to be a gelid point in the history of south Africa whereby the white minorities, mainly the descen dants of the anglo-dutch people that have been ruling since the 18th century decided to demo laws that favours ethnic segregation, discrimination, racial classification, racial domination and profiling and the general universe of class structure. The foregoing led Nengwekhulu to ob work on that the white racism and the reefer of racial spirit by blacks cannot therefore just be cut on the basis that they are expression of false consciousness and epiphenomena of the economic base (Nengwekhulu, p.29). The scheme of grand apartheid, which begun at that time and lead to the define separate schooling, stemmas, pay and places to live, and deprived most black Africans of citizenship in second Africa. Forgetting the fact that Africans has the tradeive and growing majority in southeasterly Africa, while whites are the minority national liberation there would mean a profound substitute in who ruled. Nengwekhulu, in his article, explain further in the problems faced by the atomic nu mber 16 African people with the illustration that South African situation and in formulating strategies for the elimination of black domination and using whilst according to both race and ethnicity a place and role in this summary and formulation of a strategy for black liberation and for complaisant change (ibid, p.30). In other words, we can say the affair of race, class and ethnicity is not only of crucial abstractive only it is too a matter of antecedentful political significance for it is on the basis of the closedown of this top dog that the proper ground work can be fit(p) not only for political strategies for the repugn against black exploitation but also for the construction of a future South Africa. Race discrimination, prepossess and ideology in South Africa are therefore not what happens or what people do without trying to change anything or oppose them in fundamentals of whose existence is determined automatically. They are however social matter which is no t fully understood with a relative autonomy. For this reason, race discrimination and prejudice has always existed between the blacks and white and the colours in South Africa now they interact with each other while maintaining their identities. The incidence of apartheid in South Africa from 1948 to 1994 could be linked in retrospect to a form of social misnomer that is opposed to the classical form of Marxism. Marxism is based upon a materialist definition of history. Taking the persuasion that social change occurs because of the contest between different classes and races indoors society who are under contradiction of one against the other. The loss analysis leads to the conclusion that capitalist economy, the currently prevalent form of economic management, leads to the oppression of the lying-in as in the case of the South African apartheid era, who not only make up the majority of the worlds populace but who also spend their lives working for the benefit of the cautiou sie, or the squiffy ruling class in society. From the foregoing, I will attempt to explore the Marxist ideals and how it could be extended to explain the socio-economic dis-enfranchisation of the black majority as it happened in the apartheid in South Africa.MarxismThe Marxist vision of society and history was presented in the 1848 communistic Manifesto in dramatic narrative form, sketching out the rise of capitalism and burgess society and its revolutionary overthrow by the industrial proletariat (Harrington, 2005154). According to Karl Marx, Marxism is as a philosophy of history couple with an economic doctrine. He further explains Marxism also as a theory of revolution and the basic explanation for how societies go through the edge of change (Marx, p 2). He explains his idea by using two basics of ideas that is in demonstrating and explaining his idea of Marxism which they are MATERIALISM and CLASS STRUGGLE. By Materialism of Marxism, Marx aimed that the railway locomotive t hat drives society is the economy. Economic forces are more complex and pervasive than we gauge According to Marx, they even determine how we think Consciousness is from the genuinely stem a social product (Mazlish, 1984, p. 94). That is, the way at which people corporate there things in when we talk about compassionate being material intent shapes every part of humans life including the most important aspects that could include general character of the societal, society, public, political, and spiritual or religious practice of life. This could also be that it does not have to be that the swell up being of human that can prove the fact of their state of being but having in mind that the social life of human can also be a determinant in their consciousness. By Class Struggle which is the idea that is applicable to the problem of class structure in South Africa. Marxist analysis takes historical materialism a step further. All of human history can be explained and predicted by the competition between contrastive economic classes, or as Marx perpetrate it, The history of all til now existing society is the history of class struggles. In political terms, this federal agency that the social classes are competing in essence for control of the state-or, as Marxists would wander it the class that controls the Mode of Production also controls the State (Marx, 1818-1883,p 4). The existence of class struggle that brought about the Marxist idea is applicable to the situation of South Africa because South Africa in the time of the apartheid government or ruler was one of the most hideously racist administrations during the time of twentieth century, a very obvious case of the bourgeois ruling class oppressing the majority proletariats (Zain, 20098). This struggle lead to the idea that social change occur due to class and race problem of discrimination between white and black South Africans.The existence of class struggle which is one of the basic tenets of M arxism as understandably evident in the case of South Africa sought to overcome the principle and reductionism of Stalinism and Trotskyism, to engage with history as a living process rather than a mechanical formula, to found a historical consciousness linking local struggles to global processes, and implant itself in a working-class faeces which sought to control its own destiny, openly and democratically, rather than submitting to the authority of nationalism or pseudo-science (Nash, 199966). In other words, it can also be noted that the regime of the apartheid in South Africa in the seventies can be seen as Western Marxism as portrayed in Douglas Kellner article. In terms of the Western Marxism, South Africa started with the recognition in the midst of white students that are not among the social force that could bring about innovative change into the country South Africa. In a global context, this generation of South African Marxists played a vital role in translation for th e Western left hand, in the terms of their own thought, a struggle which had come to be crucial to the whole history of our time (ibid 199966, quoted in Sweezy and Magdoff, 1986). In the analysis of Marx and Engels who are the author of Marxism, cultural ideas of a period serve is always to the comfort of the ruling class, providing ideologies that justifiable the domination of class. They make analysis of Ideology clarifying it as a critical term for Marxian that describes how dominant ideas of a ruling class promote the inte respires of that class and help pretend oppression, injustices, and negative aspects of the specific culture, society or country. The introduction of the apartheid in South Africa includes the above mentioned in the case whereby most of the blacks were separated from the white. The blacks South Africans were leaving in a place where they can be classified as the lower class group and the white due to the kind of job and the place they live are seen as the hi gh class and that is what the brass of the apartheid illustrate segregation. At every situation in South Africa, white students or the white ethnic group were in a lot of ways allowed to their opinions and decisions on their own different individualities, with limitation that could do as ethical individuals that has no living history of struggle to be set with, which includes the family relationship to their history.Marxism as the political and economic theories of Karl Marx during the 1818 1883 that should soften details of the changes, alterations, modifications and developments in a particular society or country that is implanted by implementing fabianism. The implementation of socialism was supposed to be based on the look that everyone has the same equal right in a countrys at which the government would have to own and control the main industries and not by private settings. But in the case of South Africa, the ruling system by the apartheid regime was not for equal rig ht or for the development of the changes that were altered, but it brought differences between the black and the white which could be seen as racial dominant in South Africa. In other words, instead of the implementation of socialism, the case of South Africa led to capitalism. That is, instead of equal right as socialism represent it was a system at which South Africa countrys businesses and industry are controlled and run for profit by private owners (the Afrikaners (whites)) which means I am not free to be open to the other as a person. I have to manipulate the other in such a way as to obtain things. And to manipulate the other I have to manipulate myself (Wolpe, 198021). In other words, capitalism did not basically take advantage of human beings whose underlying identity or personality was left otherwise indifferent by their experience of class mismanagement. The regime of apartheid which is that practices of capitalism in South African can be viewed as the focussed and attent ion to the relationship between the countrys economy and its polity, specifically on the relationship between class and race to build differences, racial capitalism and segregation between the working class people and the lower class people and South Africa being an Africa and a black country at voluminous which was ruled by the white government who came up with the system of apartheid which was viewed as racial domination.Thus, the Marxism ideology is used to analyze the situation that occurred in the 1970s to 1980s till the end of apartheid in 1994 in South Africa. This is because when the white (the Germans, French, Irish and the British) who are known at the long run as the Afrikaners because of their way of life, and due to believes and culture and also that the Afrikaners view themselves as Africans and not as white people. They brought churches and believe into South Africa and because of the culture and believe they brought, these made the main South Africa people to believ e in them and be rest assured of their words and whatever they promised of doing. Even though they are seen as the minority, they still have principal contributions to what is happening in the country and to the state of matter and donts in South Africa. With these minds of the Afrikaners, they created a political party that promised the people and the ethnic South Africans as a result of their trusts and basic cultural beliefs and ideologies allowed the white Afrikaans to have their ways. Part of the campaign during the election was the introduction of Apartheid which was introduced in 1948 to be practiced. Thereafter they implemented series of laws that promises a lot as the ideology portrays which is supposed to be for socialism but instead lead to segregation of the white and the blacks in South Africa. The idea of Marxism is to create equal right for everyone in the country while the government alone rule the country at which the Marxist theory is implemented. On the contrary in an unfortunate manner, most of the countries at which the Marxist theory was implemented did not survive with the Marxist theory due to the wrong implementation of the theory. The question of the place, role and relationship of race, class and ethnicity is not only of crucial theoretical significance but it is also a matter of billetful political significance (Nengwekhulu, p 30). The white South Africas used the apartheid and the implementation of Marxism which they promised during the campaigns to determine economic advantages and these economic advantages they never want to lose for any reason because it is of a great impact to their racist regime. A similar accompaniment in some other countries has led to serious outcomes. If we take the case in France during the 18th century, the practices of oppression lead to war between the bourgeois and the proletariats. In their case, the bourgeois are the upper class people, the ruling class, and wealthy people while the proletariats are the working class people. Therefore because the bourgeois are the ruling class, they believe in power and used their power in differentiation and segregation between the working and the ruling class which later lead to war. As a result of these in South Africa, equal right as the theory portrays, the white goes to different schools, live in a separate environment, work in separate place and they have no say in what is going on within the country. The apartheid government isolate and keep apart the education, health care, and other community work, thereby make available black people with lower services compare to those of white people. Apartheid and the non-implementation of the straight tenets of Marxism, led to recondite class member between races and classes in South Africa failed because theirs was an oppressive form of government that put class wedges between different races and classes in the country. The race, class and separation of the white from the black in South Africa eventually lead to the struggle of class and race structure. In the manner, the black South Africans struggle for their race and class.The black South Africans during the racist regime in the 1970s to the 1980s which was the apartheid regime, after being promised a lot but instead was initiated with differences, maltreatment and segregation lost trust in the National Party (NP) people and had to struggle for their right which is equal right for everyone. In other words, non implementation of the true ideals of Marxism led to deep divide between the races and classes of people in South Africa. Nowadays, since 1994 onwards, we have a succession of governments that tries to practice equality among the disparate genders and classes of South Africa. The issue of racial discrimination and ethno-centric profiling has been reduced to the barest minimum. People are no longer hounded or massacred when they demand for their rights under the ethics citizenship as opposed to what happened in the Sharpeville massacre of the 1950s. Although we still have to a quite subliminal level the issue of class relating to the economic situations of the different classes of South Africans but the same is what is happening in many other countries that practices relax form of Marxism laced with high doses of Socialism such as the case of South Africa. It still remains a highly agrarian country but in the general case, it is no longer at the subsistence level. The proletariats that are majorly involved in the mining business now have a satisfying sense of belonging. Racial desegregation of South Africa has brought about unwashed economic emancipation to the hitherto different classes of people as people that use to initially feel disenfranchised in their homeland now seems to have enhanced sense of belonging.The country still have its normal problem of crime, intrinsic economic instabilities, manipulation of governmental policies and general increase in awareness among the popula ce of the lassitude of their economic drive, but the same trend is being witnessed in several other developing countries that are middle ranked in the committee of nations such as South Africa. No longer do we have issues that relate to economic flatness provoked by racial disparities and ethnic discrimination. South Africa in concomitant years as a country is still trying to disunite from the lethargy and scariness harbingered by the Apartheid era but we now have in the country peace occasioned by sense of belonging.The general feelings in South Africa now are revealed through one of the speeches of Nelson Mandela after voting in the outset South African democratic election and took the office in 1994, which initiates a new regime. Now we moved from a regime of doubt, separation, limited opportunities, disoblige and conflict. In other word, a new era is starting to give hope, resolution and to build the nation. Thus a genuinely cast of elector results will give prospect to al l the South Africans and make them wee the country is theirs and they are one nation.The speech thus goes that the fundamental requirements of majority of the citizens will be talked, such as the provision for employment, accommodation, and the initiation of power supply. Including the constructions of schools and hospitals, providing free, compulsory quality education, running water, paved roads (Natal, 1994) stating that these are their main concern which includes the minorities the white (Afrikaners). He made clear citizens should have self-assurance also that there would be security to those who are bothered that by these transformations and revolutions, which might not be of benefit or improvement to them. I again repeat that I have throughout my life as I pointed out in the Rivonia Trial I have fought very firmly against white domination. I have fought very firmly against black domination. I cherish the idea of a new South Africa where all South Africans are equal and work t ogether to bring about security, peace and democracy in our country. I sincerely hope that the mass media will use its powerful position to ensure that democracy is installed in this country (ibid 1994). Since this historic speech at Inanda, Kwazulu Natal in April 1994, South Africa has continued to grow in leaps and bounds albeit with the normal problems that a bud and truly developing country might experience. From the foregoing, it could be inferred that any country that intermarry the basic tenets of the proletariat Marxism with democratic ideals may very well reap the benefits. However, the practices of these ideals must be in sync with true paying attention for the basic and fundamental rights of the citizenry. No nation may be able to move forwards if these ideals are violated.In many other countries of the world such as Iran in 1979, Russia in 1917 and France in 1789-1799, ruler ships by potentates and maximum rulers were done away with due to their well documented lack of c are for the needs of the proletariats and the masses in their charge. In these countries, the initial deep chasm between the rulers and the proletariats were very well abridged due to introduction of class and ethnic declassification. So also in South Africa, the gain of racial declassification since 1994 and the introduction of almost a classless society is still blossoming and times will be able to show if truly the new trend could be maintained well into the future and if it will truly continue to benefit the entire people of South Africa.

Simulation Module for Patients with Hypoglycemia

Simulation Module for Patients with HypoglycemiaDevelopment and valuation of Simulation Module for Patients with HypoglycemiaINTRODUCTIONBackgroundHuman unhurried simulator (HPS) has been used in medical didactics (Alinier, Hunt, Gordon, Harwood, 2006) for al about four decades. Since framework utilize high-fidelity has begun by applying crisis intervention occupying on suck up anesthetist (Fletcher, 1995), over the past 10 years, exemplar has been rapidly spread out in c be for education (Dunn, 2004).Simulation education is not skillful closely obtaining simple knowledge and techniques but rather have been considered as a kind of new education mode that digest train nurse care might by reproducing solid-like clinical federal agency in a safe environment (Hodge, Martin, Tavernier, Perea-Ryan, Alcala-Van Houten, 2008 Steadman et al, 2006). Moreover, pretension education have been speed up by shortening of the forbearings admission period and modified chances of care for scholars participation due to elevated expectations on the medical staff by the patients.Through excuse education, student await out physical examination directly on simulator and immediately separate physiological changes on the monitor. After implementing the proper intervention, they can get feedbacks from results (Bremner,Aduddell,Bennett, VanGeest, 2006). accordingly education utilize seeming is becoming the most eventful defeat in current breast feeding education as a method acting that can break problem solving ability and critical idea of students in clinical situation (Corbridge, McLaughlin, Tiffen, Wade, Templin, Corbridge, 2008 Feingold, Calaluce, Kallen, 2004).Since a simulation pattern method has been introduced to the nursing practice educating in South Korea ten years ago, many a(prenominal) meditate results on the effect of simulation education have been inform in the area of pediatric nursing (Yoo, 2013 Shin, Shim, lee(prenominal), 201 3), maternity nursing practicum (Kim, Ko, Lee, 2012 Kim, Lee, Chae, 2012 Lee Kim, 2011), psychiatric nursing (Choi, 2012), and critical and emergency care unit (Kim, Choi, Kang, 2011 Kim Jang, 2011). original scenario that can be used in simulation education is not still genuine variously in sub-major nursing areas in Korea. and so case is not appropriate to situation so there is a difficulty of having simulation practice. Especially, diabetes mellitus is prevalent disease in middle ages. However, it can be controlled by both concrete assessment for differentiation and anticipatory management. And because patients with diabetes mellitus should always manage blood glucose in their life, nursing education to foreclose hypoglycemia is essential education essences. In nursing student education, simulation practice for critical thinking training to identify symptoms and plan nursing care as precedingity due to hypoglycemia is effective and important nursing problem.In this translate, we tried to test the applicability of the simulation by growing simulating education scenario based on the case of hypoglycemia and evaluating students performance after using it. The study was d hotshot to improve nursing students critical thinking on nursing problems and clinical decision-making ability by developing scenario with high-fidelity SimMan simulator based on clinical real situation. The purpose of this study is to develop a scenario and evaluate students performance and expiation in simulation learning of care for patients with hypoglycemia.METHODDesignThis study used a mixed method design which captured both vicenary and qualitative data to evaluate degree of performance and satisfaction as development and applying simulation module with hypoglycemia. In disciplines such as nursing, the phenomena canvass are often complex and mixed-method approaches can expand the impact and enhance the flexibility of research designs (Sandelowski, 2000)ParticipantsA convenience sample of 55 nursing students participated from a university located in Seoul, South Korea. We have decided that triplet year nursing students who have enough basic knowledge on pathophysiology entrust not have difficulty in applying simulation education on patient with hypoglycemia and developed simulation scenario targeting them. The inclusion criteria to collide with hypoglycemia included (a) junior nursing students, (b) completion of fundamental and internal secretion system nursing course with the same credits and textbook, and (c) no prior participation in a simulation class focused on diabetes mellitus.The participants ages ranged from 21 to 25 years. The majority of students 89% were women.Ethical conside rationsApproval to apportion this study was obtained from the Sahmyook university institutional review board (SYUIRB-2013-074). Written informed have consist of issues of voluntary participation, anonymity, and confidentiality. It explained the purpose o f study, the researchers credentials, and information regarding confidentiality. Collected data will be managed in the researcher office and will be rip up after coding. The IRB proved that there were no factors to this study that would deprive pitying ethical right, and that all contents and processes confirm to proper research ethics. performance of module developmentScenario developmentContents of scenario were developed based on real patients situation which admitted to emergency unit with blast symptom due to hypoglycemia. In addition, we searched more information on nursing care for hypoglycemia from nursing textbook and protocol. Scenario was focused on developing of students ability round assessment and problem naming by critical thinking. For this, the purpose of scenario formulation was to differentiate the origin of profane symptom between hypoglycemia and increasing of intracranial pressure. For testing of validity, v experts consisted of tierce nursing professor s, deuce nurses who have worked in emergency unit over 10 years reviewed contents of scenario. The scenario was pilot tested using flipper students (not included in the present study) to determine feasibility and clarity of instructions. No problems were identified.Development of evaluation checklistThe evaluation checklist focused on the advance of critical thinking ability rather than implementation skill and was divided into three categories assessment, problem identification, and interventions. Finally, 4 percentage points were deleted and 16 items reached by consensus (Table 1). The items were selected, reviewed, and analyzed by a seven expert panel including two nursing professors, five advanced practice nurses.Process of question question questions were also developed focused on critical thinking as three stage process. Description phase What decision did you make when patient complains dyspnea? wherefore did you do? Analysis phase Did you have an enough understandin g about nursing care for patient with hypoglycemia after this simulation practice? and Application phase How can you cope real nursing situation in future through what you learned?. These three phases for questioning are based on clinical judgment model by tan (2006). After taking simulation practice, students had debriefing time for about 2030 minutes per group of four students. The nursing students were encouraged to strike on their critical thinking.Data collection procedureData were serene from May6, 2013 to June 28, 2013. The studys purpose and its procedures were explained to the participants prior to obtaining informed consent. All participants enrolled in this study voluntarily and anonymously, were made aware that there was no injustice to nonparticipation as well as information regarding confidentiality. In addition, the data would be reported as a whole and not individually. The ratio of participation was 98%.Before the simulation, students received an orientation th at included how to lease the simulator, simulation learning objective, the scenario information, and patients health status. Four nursing students have teamed up to have a discussion of the simulation scenario. Students were asked to erosion uniforms and to treat these as actual professional situations. The simulations were scheduled in simulation rooms in which the high-fidelity patient simulators were used. One operator and one instructor observed the simulations from the control room. Each simulation lasted 20 minutes, with the simulation module including debriefing taking about two hours per group. The evaluation checklist was evaluated as a group and was handed to two instructors in a cockeyed envelope. After simulation module, student satisfaction was measured using the cheer of Simulations Experience (SSE).InstrumentsThe evaluation checklist tool using 3-point Likert scale (1 not fulfill, 2 partially fulfill, 3 fulfill) was a researcher-developed tool designed to assess s imulation-based performance. The high the evaluation checklist nock, the better the performance. Content validity was conducted from nurse educators, simulation experts, and clinicians (n=10). The results of the content validity index were above 80% (Waltz and Bausell, 1981). Inter-rater reliability between two independent raters was established using Cohens kappa.Satisfaction which students felt about simulation practice was measured just after finishing the debriefing session using the Satisfaction of Simulations Experience (SSE) scale developed by Levett-Jones and colleagues (2011). This scale consists of 18 items in the area of debrief and reflection (9 items), clinical reasoning (5 items), and clinical learning (4 items). Each item was scored on a 5-point Likert scale. Higher scores indicated higher satisfaction. Cronbachs alpha coefficient in this study was .94.Data analysisThe evaluation checklist and the SSE were analyzed using SPSS 18.0 for Windows to take descriptive st atistics including reputes and standard deviations. Debriefing data were analyzed using the Matrix Method (Garrad, 2007). Four researchers was analyzed all papers cogitate to debriefing. It were photocopied and organized as a review matrix that, once designate appropriately, would serve as a structured abstract of all of the documents. The 3Cs (i.e., codes, categories, and concepts) of analysis was used to capture key characteristics of interest, thereby summarizing a epic amount of textual information into pissedingful themes (Lichtman, 2006).RESULTScenario of simulation-based hypoglycemiaThe patients case was developed based on scenario objectives and performance measures. The phoney patient was a 55-year-old man admitted via the emergency unit complaining of giddiness and sweating. The algorithm proceeded as follows assessment, problem identification, intervention (Fig. 1).Evaluation ChecklistThe evaluation checklist consisted of three categories and 16 items. To identify a statistical measure of inter-rater agreement for items, Cohens kappa was measured. Cohens kappa for the evaluation checklist was 0.61, good strength of agreement, and each category ranged from 0.33 to 0.97.The mean score of each category and item is shown in Table 1. The mean score is average of numbers of two measurers. The total mean score was 2.68 (.129). The mean score of assessment was 2.56 (.199), problem identification was 2.91 (.193), and intervention was 2.71 (.192).DebriefingStudent comments about the simulation birth were grouped 2 categories, 9 subcategories, and 303 significant statements using content analysis (Table 2). The categories were as followed Self-reflection and Improvement of competency. The most frequent subcategories, in order, were nursing intervention, coping ability deficiency, perception of real situation, clinical thinking deficiency, knowledge deficiency and communication.Satisfaction with simulation experienceThe SSE scale was used to assess part icipation in the simulation experience. The total mean score of SSE was 4.15 (.68). The mean score for debrief and reflection was 4.21 (.58), clinical reasoning was 4.09 (.50), and clinical learning was 4.08 (.46). The highest score item in SSE was I received feedback during the debriefing that helped me to learn, and the last-place was The facilitator made me feel comfortable and at ease during the debriefing (Table 3).

Forced Vibrations Of Simple Systems English Language Essay

Forced Vib dimensionns Of Simple Systems English Language assayMechanical, acoustic, or electrical quiverings atomic number 18 the comes of fit in medical specialtyal operators. some(a) familiar examples atomic number 18 the vibproportionns of caravans violin, guitar, piano, etc. bars or rods xyloph champion, glockenspiel, chimes, and clari mavent reed, membranes (drums, banjo), plates or shells (cymbal, gong, bell), logical argument in a furnish (organ pipe, brass and woodwind presentzs, marimba resonator), and advertize in an enfold container (drum, violin, or guitar body). In most instruments, conk merchandise dep hold backs upon the collective behavior of some(prenominal) vibrators, which may be weakly or strongly coupled together. This coupling, along with nonlin ear feedback, may ca handling the instrument as a whole to be experience as a coordination compound vibrating administration, even though the individual elements atomic number 18 relatively st raightforward vibrators (Hake and Rodwan, 1966).In the first seven chapters, we go forth discuss the physics of mechanical and acoustical oscillators, the way in which they may be coupled together, and the way in which they radiate sound. Since we ar non discus the pitsg electronic musical instruments, we exit not deal with electrical oscillators except as they swear bug out us, by analogy, to go steady mechanical and acoustical oscillators.According to Iwamiya, Kosygi and Kitamura (1983) many objects are candid of vibrating or oscillating. Mechanical vibrations require that the object possess cardinal basic properties a stiffness or spring like quality to provide a restoring force when displaced and inertia, which causes the resulting deed to overshoot the equilibrium position. From an animation stand psyche, oscillators keep a manner for storing probableity energy (spring), a means for storing energising energy ( troop), and a means by which energy is gradu altoget hery lost (damper). vibratory movement involves the alternating transfer of energy in the midst of its kinetic and potential forms. The inertial mass may be either concent layd in one location or distri justed throughout the vibrating object. If it is distributed, it is usu bothy the mass per building block continuance, area, or glitz that is important. Vibrations in distributed mass organisations may be viewed as standing waves. The restoring forces depend upon the elasticity or the compressibility of some material. just about vibrating bodies obey Hookes law that is, the restoring force is proportional to the translation from equilibrium, at to the low degree for minuscular supplanting.Simple harmonical motion in one markMoore (1989) has mentioned that the straightforwardst kind of periodic motion is that experienced by a depict mass lamentable along a straight line with an speedup directed toward a fixed draw a bead on and proportional to the infinite from that p oint. This is c exclusivelyed simple harmonic motion, and it chiffonier be set forth by a sinusoidal function of time, where the bounteousness A describes the supreme extent of the motion, and the absolute oftenness f tells us how often it repeats.The period of the motion is inclined byThat is, each(prenominal)(prenominal) T bet ons the motion repeats itself.Sundberg (1978) has mentioned that a simple example of a system that levitates with simple harmonic motion is the mass-spring system shown in Fig.1.1. We assume that the measuring stick of stretch x is proportional to the restoring force F (which is true in most springs if they are not stretched too far), and that the mass slides freely without personnel casualty of energy. The equation of motion is easily obtained by combining Hookes law, F = -Kx, with Newtons trice law, F = ma =. Thus,andWhere=The constant K is called the spring constant or stiffness of the spring (expressed in Newtons per meter). We define a co nstant so that the equation of motion becomesThis well-known equation has these dissolving agents) work up 2.1 Simple mass-spring vibrating system radical Cremer, L., Heckl, M., Ungar, E (1988), Structure-Borne Sound, 2nd edition, Springer VerlagFigure 2.2 Relative anatomy of switching x, velocity v, and acceleration a of a simple vibratorSource Campbell, D. M., and Greated, C (1987), The Musicians Guide to Acoustics, Dent, LondonorFrom which we recognize as the ingrained angular relative frequency of the system.The natural frequency fo of our simple oscillator is given by and the amplitude by or by A is the initial stagecoach of the motion. Differentiation of the displacement x with respect to time gives be expressions for the velocity v and acceleration a (Cardle et al, 2003),And.Ochmann (1995) has mentioned that the displacement, velocity, and acceleration are shown in Fig. 1.2. Note that the velocity v leads the displacement by radians (90), and the acceleration leads (or lags) by radians (180). Solutions to second- secern differential equations have devil arbitrary constants. In Eq. (1.3) they are A and in Eq. (1.4) they are B and C. Another alternative is to describe the motion in enclosures of constants x0 and v0, the displacement and velocity when t =0. Setting t =0 in Eq. (1.3) gives and setting t = 0 in Eq. (1.5) gives From these we give the axe obtain expressions for A and in terms of xo and vo,andAlternatively, we could have set t= 0 in Eq. (1.4) and its derivative to obtain B= x0 and C= v0/ from which.2.3 composite amplitudesAccording to Cremer, Heckl and Ungar (1990) another approach to solving linear differential equations is to use exponential functions and tangled variables. In this description of the motion, the amplitude and the phase of an oscillating quantity, such as displacement or velocity, are expressed by a decomposable number the differential equation of motion is change into a linear algebraic equation. The advantages of this formulation depart become more(prenominal) apparent when we con sider driven oscillators.This alternate approach is based on the mathematical identity where j =. In these terms,Where Re stands for the real smash of. Equation (1.3) evoke be written as,Skrodzka and Sek (2000) has mentioned that the quantity is called the complex amplitude of the motion and re dis gos the complex displacement at t=0. The complex displacement is writtenThe complex velocity and acceleration becomeDesmet (2002) has mentioned that individually of these complex quantities cigaret be thought of as a rotating vector or phase rotating in the complex plane with angular velocity, as shown in Fig. 1.3. The real time dependence of each quantity send packing be obtained from the projection on the real axis of the corresponding complex quantities as they rotate with angular velocityFigure 2.3 Phase representation of the complex displacement, velocity, and acceleration of a linear oscillatorSource Bang tsson E, Noreland D and Berggren M (2003), roll optimization of an acoustic horn, Computer Methods in Applied Mechanics and Engineering, 1921533-15712.4 a oscillation-the-clock systems in one dimensionStrings and barsThis section focuses on systems in which these elements are distributed continuously throughout the system rather than seem as discrete elements. We begin with a system composed of several discrete elements, and then allow the number of elements to grow larger, eventually hint to a continuum (Karjalainen and Valamaki, 1993).Linear array of oscillatorsAccording to Mickens (1998) the oscillating system with two masses in Fig. 1.20 was shown to have two transverse vibrational agencys and two longitudinal trends. In both the longitudinal and transverse p dividing lines, at that place is a mode of low frequency in which the masses move in the aforementioned(prenominal) direction and a mode of prouder frequency in which they move in opposite directions. The lingui stic rule modes of a terce-mass oscillator are shown in Fig. 2.1. The masses are constrained to move in a plane, and so there are six normal modes of vibration, trinity longitudinal and tierce transverse. from each one longitudinal mode testament be higher(prenominal) in frequency than the corresponding transverse mode. If the masses were free to move in three dimensions, there would be 3*3 =9 normal modes, three longitudinal and six transverse.Increasing the number of masses and springs in our linear array increases the number of normal modes. Each new mass adds one longitudinal mode and (provided the masses move in a plane) one transverse mode. The modes of transverse vibration for mass/spring systems with N=1 to 24 masses are shown in Fig. 2.2 note that as the number of masses increases, the system takes on a wavelike appearance. A similar diagram could be drawn for the longitudinal modes.Figure 2.4 radiation pattern modes of a three-mass oscillator. Transverse mode (a) has the lowest frequency and longitudinal mode (f) the highestSource Jaffe, D and Smith, J (1983), Extension of the Karplus-Strongplucked background algorithm, CMJ 72, 43-45Figure 2.5 Modes of transverse vibration for mass/spring systems with different add up of masses. A system with N masses has N modesSource Beranek L (1954), Acoustics. McGraw-Hill, New YorkAs the number of masses in our linear system increases, we take less and less notice of the individual elements, and our system begins to agree a vibrating power train up with mass distributed uniformly along its distance. Presumably, we could describe the vibrations of a vibrating gear by writing N equations of motion for N equation spaced masses and letting N go to infinity, but it is often simpler to consider the precondition of the string as a whole (Bogoliubov, and Mitropolsky, 1961). stand up wavesConsider a string of aloofness L fixed at x=0 and x= L. The first limit y (0,t) = 0 requires that A = -C and B = -D i n Eq. (2.9), so development the sum and resi cod formulas, sin(xy) = sin x cos y cos x sin y and cos(xY = 2A sin kx cos= 2A cosThe second condition y (L, t) =0 requires that sin kL =0 or . This restricts to comforts Thus, the string has normal modes of vibration (Obrien, Cook and Essl, 2001)These modes are harmonic, because each fn is n multiplication f1= c/2L.The general solution of a vibrating string with fixed ends can be written as a sum of the normal modesand the amplitude of the ordinal mode is. At any pointAlternatively, the general solution could be written asWhere Cn is the amplitude of the nth mode and is its phase (Keefe and Benade, 1982).2.5 Energy of a vibrating stringMcIntyre et al (1981) has mentioned that when a string broods in one of its normal modes, the kinetic and potential energies alternately take on their maximum value, which is equal to the total energy. Thus, the energy of a mode can be numberd by considering either the kinetic or the potential energy. The maximum kinetic energy of a segment vibrating in its nth mode isIntegrating over the entire length givesThe potential and kinetic energies of each mode have a time average value that is En/2. The total energy of the string can be ensnare by summing up the energy in each normal modePlucked string time and frequency analysesAccording to Laroche and Jot (1992) when a string is excited by condescending, plucking, or striking, the resulting vibration can be considered to be a combination of several modes of vibration. For example, if the string is plucked at its center, the resulting vibration will consist of the fundamental plus the odd-numbered harmonics. Fig. 2.5 illustrates how the modes associated with the odd-numbered harmonics, when each is present in the right proportion add up at one instant in time to give the initial shape of the center-plucked string. Modes 3,7,11, etc., moldiness be opposite in phase from modes, 1, 5, and 9 in order to give maximum displacement at the center, as shown at the top. decision the normal mode spectrum of a string given its initial displacement calls for frequency abstract or fourier analysis.Figure 2.6 snip analysis of the motion of a string plucked at its midpoint through one half cycle. Motion can be thought of as due to two pulses travelling in opposite directionsSource Gokhshtein, A. Y (1981), portion of behaviorow modulator in the excitation of sound in wind instruments, Sov. Phys. Dokl. 25, 954-956Since all the modes shown in Fig.2.6 have different frequencies of vibration, they quickly get out of phase, and the shape of the string changes rapidly after plucking. The shape of the string at each moment can be obtained by adding the normal modes at that particular(a) time, but it is more severe to do so because each of the modes will be at a different point in its cycle. The declaration of the string motion into two pulses that propagate in opposite directions on the string, which we might call time analysi s, is illustrated in Fig.2.6 if the constituent modes are different, of course. For example, if the string is plucked 1/5 of the exceed from one end, the spectrum of mode amplitudes shown in Fig. 2.7 is obtained. Note that the 5th harmonic is missing. Plucking the string of the distance from the end suppresses the fourth harmonic, etc. (Pavic, 2006).Roads (1989) have mentioned that a time analysis of the string plucked at 1/5 of its length. A sheepcote rush along back and forth within a parallelogram boundary can be viewed as the resultant of two pulses (dashed lines) travelling in opposite directions. Time analysis through one half cycle of the motion of a string plucked one-fifth of the distance from one end. The motion can be thought of as due to two pulses moving in opposite directions (dashed curves). The resultant motion consists of two sheepcotes, one moving clockwise and the other counter-clockwise around a parallelogram. The normal force on the end support, as a funct ion of time, is shown at the bottom. Each of these pulses can be described by one term in dAlemberts solution Eq. (2.5).Each of the normal modes described in Eq. (2.13) has two coefficients and Bn whose values depend upon the initial excitation of the string. These coefficients can be determined by Fourier analysis. Multiplying each side of Eq. (2.14) and its time derivative by sin mx/L and integrating from 0 to L gives the following formulae for the Fourier coefficientsBy using these formulae, we can calculate the Fourier coefficients for the string of length L is plucked with amplitude h at one fifth of its length as shown in intent.2.8 time analysis above. The initial conditions arey (x,0) = 0y (x,0) = 5h/L .x, 0 x L/5,= 5h/4 (1-x/L), L/5 x L.Using the first condition in first equation gives An=0. Using the second condition in second equation gives==The individual Bns become B1 =0.7444h, B2 =0.3011h, B3 =0.1338h, B4 =0.0465h, B5 =0, B6= -0.0207h, etc. Figure 2.7 shows 20 log fo r n=0 to 15. Note that Bn=0 for n=5, 10, 15, etc., which is the signature of a string plucked at 1/5 of its length (Shabana, 1990).Bowed stringWoodhouse (1992) has mentioned that the motion of a gesture string has interested physicists for many years, and untold has been written on the subject. As the bow is drawn across the string of a violin, the string appears to vibrate back and forth smoothly between two curved boundaries, much like a string vibrating in its fundamental mode. However, this appearance of informality is deceiving. Over a hundred years ago, Helmholtz (1877) showed that the string more tight forms two straight lines with a sharp bend at the point of intersection. This bend races around the curved path that we see, making one round trip each period of the vibration.According to Chaigne and Doutaut (1997) to observe the string motion, Helmholtz constructed a vibration microscope, consisting of an eyepiece attached to a tune fork. This was driven in sinusoidal mot ion parallel to the string, and the eyepiece was focused on a bright-colored spot on the string. When Helmholtz bow down the string, he saw a Lissajous account. The figure was stationary when the tuning fork frequency was an integral function of the string frequency. Helmholtz noted that the displacement of the string followed a triangular pattern at whatever point he observed it, as shown in Fig.2.7Figure 2.7 Displacement and Velocity of a motion string at three positions along the length a) at x = L/4 b) at the center, and c) at x = 3L/4Source Smith, J (1986), Efficient pretension of the Reed-Bore and Bow-String Mechanisms, Proc. ICMC, 275-280The velocity waveform at each point alternates between two values. Other early work on the subject was produce by Krigar-Menzel and Raps (1891) and by Nobel laureate C. V. Raman (1918). More recent experiments by Schelleng (1973), McIntyre, et al. (1981). Lawergren (1980), Kondo and Kubata (1983), and by others have verified these early findings and have greatly added to our transforming of bowed strings. An pure discussion of the bowed string is given by Cremer (1981). The motion of a bowed string is shown in Fig.2.8Figure 2.8 Motion of a bowed string. A) Time analysis of the motion showing the shape of the string at eight successive times during the cycle. B) Displacement of the bow (dashed line) and the string at the point of contact (solid line) at successive times. The letter correspond to the letters in (A)Source McIntyre, M., Woodhouse, J (1979), On the Fundamentals of Bowed-String Dynamics, Acustica 432, 93-108Dobashi, Yamamoto and Nishita (2003) have described that a time analysis in the above figure 2.8 (A) shows the Helmholtz-type motion of the string as the bow moves ahead at a constant speed, the bend races around a curved path. Fig. 2.8 (B) shows the position of the point of contact at successive times the letters correspond to the frames in Figure 2.8(A). Note that there is a single bend in the bow ed string. Whereas in the plucked string (fig. 2.8), we had a double bend. The go through of the bow on the string is often described as a stick and slip action. The bow drags the string along until the bend arrives from (a) in figure 2.8 (A) and triggers the slipping action of the string until it is picked up by the bow once again frame (c). From (c) to (i), the string moves at the speed of the bow. The velocity of the bend up and down the string is the usual . The envelope around which the bend races the dashed curve in Figure 2.8 (A) is composed of two parabolas with maximum amplitude that is proportional, within limits, to the bow velocity. It also increases as the string is bowed nearer to one end.2.6 Vibration of aura columnsAccording to Moore and Glasberg (1990) the familiar phenomenon of the sound obtained by blowing across the open and of a reveal shows that vibrations can be set up in an air column. An air column of expressed length has a definite natural period of vib rations. When a vibrating tuning fork is held over a tall glass is pured gradually, so as to vary the length of the air column, a length can be obtained which will resound loudly to the note of the tuning fork. thence it is the air column is the comparable as that of the tuning fork.A vibration has three important characteristics namely frequenceAmplitudePhase2.6.1 Frequency-Frequency is defined as the number of vibration in one second. The whole is Hertz. It is normally denoted as HZ. Thus a sound of gm HZ means 1000 vibrations in one second. A frequency of 1000 HZ can also be denoted as 1 KHZ. If the frequency range of audio equipment is mentioned as 50 HZ to 3 HZ it means that audio equipment will function within the frequency range between 50HZ and 3000 HZ.2.6.2 Amplitude-Amplitude is defined as the maximum displacement experienced by a particle in figure will help to understand amplitude. Let us consider two vibrating bodies having the same frequency but different amplitudes . The body vibrating with more amplitude will be louder than the body vibrating with less amplitude. The following figure represents two vibrating bodies having the same frequency but different amplitudes (Takala and Hahn, 1992).2.6.3 Phase-Phase is defined as the stage to which a particle has reached in its vibration. Initial phase means the initial stage from which the vibration take downs. The following will help to understand the concept of phase. From the source travels in the form of waves before reaching the ear sound cannot travel in vacuum. Sound needs mass medium for its travel. The medium may be a solid or liquid or gas (Brown and Vaughn, 1993).Support a glass tube open at both ends in a vertical position, with its light and dipping into water contained in a wider cylinder. Hold over the upper end of the tube a vibrating tuning form. Adjust the reinforcement of the sound is obtained. Adjust the distance of the air column till we get actually the ring or eleemosynary note. Repeat the adjustments and take the average of the results from the observation. It will be found from the repeated experiments, that the longer the air column is produced when the tuning fork becomes identical.Vibration of air column in a tube open at both ends-Obrien, Shen and Gatchalian (2002) have described that if they think of an air column in a tube open both ends, and try to imagine the ways in which it can vibrate we shall readily appreciate that the ends will always be antinodes, since here the air is free to move. surrounded by the antinodes there must be at least one node, and the ends, the moving air is either moving towards the center from both ends or away from the effect at both ends. Thus the simplest kind of vibration has a node at the centre and antinodes at the two ends. This can be mathematically expressed as followsWave length of the simplest kind of vibration is four times the distance from node to antinode 2L where L is the length of the pipe.Vibrati on of air column in a tube closed at one endThe distance from node to antinode in this case is L, the whole length of the pipe, the wavelength is therefore = 4L.2.7 Resonance-sympathetic vibrationSloan, Kautz and Synder (2002) have described that everybody which is capable of vibration has natural frequency of its own. When a body is made to vibrate at its neutral frequency, it will vibrate with maximum amplitude. Resonance is a phenomenon in which a body at rest is made to vibrate by the vibrations of another body whose frequency is equal to that of the natural frequency of the first. Resonance can also be called sympathetic vibrations. The following experiment will help to understand resonanceConsider two stretched stings A and B on a sonometer. With the help of a standard tuning form we can adjust their vibrating lengths length between the bridges to have the same frequency. Thus we can place a some publisher riders on string B and pluck string A to make it vibrate. The string B will start vibrate and paper riders on it will flutter vigorously and sometimes A can be stopped simply by touching it. Still the string B will continue to vibrate. The vibration in the string B is due to resonance and it can be called as sympathetic vibration. If kind of of the fundamental frequency one of the harmonics of string B is equal to the vibrating frequency of string A then the string B will start vibrating at that harmonics frequency. But in the case of harmonics the amplitude of vibration will be less. In Tambura when the sarani is sounded the anusarani also, vibrates thus helping to produce a louder volume of sound. The sarani here makes the anusarani to vibrate. In all musical instruments the material, the shape of the body and enclosed volume of air make use of resonance to bring out increased volume and desired upper partials of harmonics.2.8 modulationsSpiegel and Watson (1984) have described that during the course of the history of music, several of music inte rvals were proposed aiming at a high degree of maturing consonance and dissonance played important role in the evolution of musical cases. scantily intonation is the result of standardizing perfect intervals. Just Intonation is limited to one single-key and aims at making the intervals as consentient as possible with both one another and with the harmonics of the keynote and with the most associate tones. The frequency ratio of the musical notes in just Intonation is given below.Indian note Western note Frequency ratior C 1K2 D 9/8f2 E 5/4M1 F 4/3P G 3/2D2 A 5/3N2 B 15/8S C 2Ward (1970) has mentioned that most of the frequency ratios are expressed is terms of comparatively small numbers. Constant harmonics are present when frequency ratios are expressed in terms of small numbers. The interval in frequency ratio areBetween Madhya sthyai CSa and Tara sthayi csa is 2 1*2=2.Between Madhya sthyai CSa and Madhya sthayi Gpa is 3/2 1*3/2=3/2.Between Madhya sthayi DRi and Madhya sthayi EGa is 10/9 9/8*10/9=5/4Between Madhya sthyai EGa and Madhya sthayi FMa is 16/15-5/4*16/15=4/3.Between Madhya sthyai FMa and Madhya sthayi GPa is 9/8-4/3*9/8=3/2.Between Madhya sthyai GPa and Madhya sthayi ADha is 10/93/2*10/9=5/3.Between Madhya sthyai ADha and Madhya sthayi BNi is 9/8-5/3*9/8=5/8.Between Madhya sthyai SaC and Ri2D there is a svarasthanam CH. Hence the interval between SaC and Ri2D and Ga2E is known as a tone. But there is no svarasthanam semitone between Ga2E and Ma1F. Hence the interval between GaE and Ma1F is known as a semitone. Between PaG and DhaA we have a tone. Between mathya styayi Ni2B and Tara sthyai CSa we have a semitone.In just Intonation we find that tones are not all equal. But the semitones are equal. In just Intonation the modulation of key of musical notes will be difficult for example, if the keynote is changed from SaC to PaG then the frequency of etatusruthi Dhairatam A will change from 1.687, time the frequency of Sac. A musical instrument tun ed in just intonation to play sankarabaranam ragam cannot be used to play kalyani ragam. Hence the modulation of key of musical notes will be difficult in just Intonation (Doutaut , Matignon, and Chaigne, 1998). agree temperatureLehr (1997) has described that the above mentioned line in just Intonation can be solved in the rival Temperament scale. In Equal temperament all the 12 music intervals in a sthayi octave are equal. The frequency ratios of semitones in Equal temperament scale was first calculated by the French Mathematician Mersenne and was published in Harmonic Universelle in the year 1636. But it was not put into use till the latter half of seventeenth century. All keyboard instruments are tuned of Equal Temperature scale. Abraham pandithar strongly advocated Equal Temperament scale and in his celebrated music treatise karunamitha sagaram he tried to prove that the Equal Temperament scale was in practice in ancient Tamil music.A simple mathematical exercise will help to under the basis of Equal Temperament scale.Equal TemperamentMadhya sthayi Sac frequency ratio=1=2 .Tara sthayi Sai frequency ratio = 2=212/12=2.Frequency ratios of 12 svarasthanams are given below.S R1 R2 G1 G2 M1 M2 P D1 D2 N1 N2 20 21/12 22/12 23/12 24/12 25/12 26/12 27/12 28/12 29/12 210/12 2n/12S212/12All semitones are equal is Equal Temperament scale. Each represents the same frequency ratio 1.05877. The great advantage in Equal Temperament scale is that music can be played equal well in all keys. This means that any of the 12 semitones can be used as Sa in a music instrument tuned to Equal Temperament scale. in that location is no need to change tuning every time the Raga is changed. Since keyboard instruments are pre-tuned instruments they follow Equal Temperament.2.9 Production and transmission of sound-According to Boulanger (2000) the term sound is related to quite definite and specific sensation caused by the stimulation of the mechanism of the ear. The extern al cause of the sensation is also related to sound. Anybody in vibration is an external cause of the sensation. A veena after plucking or violin after blowing in a state of vibration is an external cause of the sensation. A body in a state of vibration becomes a source of sound. A vibration is a periodic to and fro motion about a fixed pointIwamiya and Fujiwara (1985) have mentioned that the pitch of a musical sound produced on a wind instrument depends on the rate or frequency of the vibrations which cause the sound. In obedience to Natures law, the column of air in a tube can be made to vibrate besides at certain rates, therefore, a tube of any particular length can be made to produce only certain sounds and no others as long as the length of the tube is un-altered. Whatever the length of the tube, these mingled sounds always bear the same relationship one to the other, but the actual pitch of die serial will depend on the length of the tube. The player on a wind instrument, b y varying the intensity of the air-stream which he injects into the mouthpiece, can produce at will all or some of the various sounds which that particular length of tube is capable of sounding thus, by compressing the air-stream with his lips he increases the rate of vibration and produces higher sounds, and by decompressing or slackening the intensity of the air-stream he lowers the rate of vibration and produces lower pitched sounds. In this way the fundamental, or lowest note which a tube is capable of sounding, can be elevated becoming higher and higher by intervals which become small and smaller as they ascend. These sounds are usually called harmonics or upper partials, and it is convenient to preserve to them by number, counting the fundamental as No. t, the octave harmonic as No. 2, and so on. The series of sounds available on a tube approximately 8 feet in length is as followsTsingos et al (2001) has mentioned that a longer tube would produce a corresponding series of sounds proportionately lower in pitch according to its length, and on a shorter tube the same series would be proportionately higher. The entire series available on any tube is an octave lower than that of a tube half its length, or an octave higher than that of a tube double its length thus, the approximate lengths of tube required to sound the various notes C are as follows Fundamental Length of tubeC, 16 feetC 8 ,.c 4,,c 2,,c I bumc 1/2,,Shonle and Horen (1980) has mentioned that the addition of about 6 inches to a 4-foot tube, of a foot to an 8-foot tube, or of 2 feet to a i6-foot tube, will give the series a tone lower (in B flat), and a proportionate bring down of the C tubes will raise the series a tone (D) on the same basis, tubes which give any F as the fundamental of a series must be about midway in length between those which give the C above and the C below as fundamental.

Their supremascy as rock icons remain unchallenged to this day, decades after their breakup in 1970. (Jansen, Lloyd 2005) however when couching praise in specific terms, it is hard to convey the scope of the Beatles achievements in a simple paragraph or dickens. They synthesized all that was good close to aboriginal rock roll, and flipd it into both(prenominal)thing original and veritable(a) more exciting. They conventional the prototype for the self-contained rock convocation that wrote and performed their avouch bodily. As bers, their craft and melodic inventiveness were entropy to none, and key to the evolution of rock from its blues/RB-based forms into a style that was farther more eclectic, provided equally visceral. As utterers, both John Lennon and jacket of Minnesota McCartney were among the best and most expressive outspoke nists in rock the crowds harmonies were intricate and exhilarating.As performers, they were exciting and photogenic when they retreated into the studio, they were instrumental in pioneering advanced techniques and multi-layered arrangements. (Jansen, 2005)They were overly the low gear British rock throng to achieve worldwide prominence, scratch appearance a British Invasion that made rock truly an international phenomenon.HistoryMore than any opposite top assort, the Beatles success was very(prenominal) often a case of the sum being greater than the parts. Their phenomenal cohesion was due in large degree to most of the conferenceing having known each other and played together in Liverpool for about five years before they began to have stimulate records. Guitarist and adolescent rebel John Lennon got hooked on rock roll in the mid 1950s, and formed a band, the Quarrymen, at his high school. Around mid-1957, the Quarrymen were get together by another guitarist, Paul M cCartney, nearly two years Lennons junior. A bit later they were joined by another guitarist, George Harrison, a conversancy of McCartneys.The Quarrymen would change lineups constantly in the late 50s, eventually reducing to the substance trio of guitarists, whod proven themselves to be the best musicians and most personally compatible psyches within the band. (Turkalo, David M 1990)The Quarrymen changed their name to the Silver Beatles in 1960, quickly drop the Silver to become just the Beatles. Lennons art college fri leftover Stuart Sutcliffe joined on bass voice, but finding a permanent drummer was a vexing difficulty until Pete vanquish joined in the summer of 1960. He successfully auditioned for the combo just before they left for a several-month stint in Hamburg, Germany.Hamburg was the Beatles baptism by fire. Playing grueling sessions for hours on give the axe in one of the most notorious red-light districts in the world, the stem was forced to expand their reperto ire, tighten up their chops, and invest their show with teeming manic energy to keep the tough crowds satisfied. When they contributeed to Liverpool at the end of 1960, the band was suddenly the most exciting act on the local circuit. They consolidated their following in 1961 with constant gigging in the Mersey military position area, most often at the legendary Cavern Club, the incubator of the Merseybeat sound.They too returned for engagements in Hamburg during 1961, although Sutcliffe dropped out of the band that year to concentrate on his art school studies there. McCartney took over on bass, Harrison settled in as bakshis guitarist, and Lennon had rhythm guitar everyone sang. In mid-1961, the Beatles made their first transcriptions in Germany, as a backup group to a British rock guitarist/singer based in Hamburg, Tony Sheridan. The Beatles hadnt fully developed at this point, and these recordings many of which (including a couple of Sheridan-less racecourses) were issued only after the bands rise to fame found their talents in a most embryonic state. The Hamburg stint was withal notable for gaining the Beatles sophisticated, aesthetical fans much(prenominal) as Sutcliffes girlfriend, Astrid Kirchherr, who influenced all of them (except Best) to restyle their quiffs in the moptops that gave the musicians their most distinctive visual trademark. tightfitting the end of 1961, the Beatles exploding local popularity caught the attention of local record store manager Brian Epstein, who was soon managing the band as well. He used his contacts to swiftly hire a January 1, 1962, audition at Decca Records that has been severely bootlegged (some tracks were officially drop offd in 1995). afterwards weeks of deliberation, Decca turned them down, as did several other British labels. Epsteins perseverance was ultimately rewarded with an audition for producer George Martin at Parlophone, an EMI subsidiary Martin signed the Beatles in mid-1962. By this meter, Epstein was assiduously grooming his charges for national success by influencing them to smarten up their appearance, dispensing with their whip jackets and trousers in favor of tailored suits and ties.One more major change was in the offing before the Beatles made their Parlophone debut. In August 1962, drummer Pete Best was kicked out of the group, a controversial decision that has been the cause of much conjecture since.There is still no solid consensus as to whether it was because of his solitary, moody spirit the other Beatles jealousy of his popularity with the fans his musical comedy shortcomings (George Martin had already told Epstein that Best wasnt good enough to drum on recordings) or his refusal to wear his hair in bangs. (Turkalo, 1990)What seems most resemblingly was that the Beatles simply found his personality incompatible, preferring to enlist Ringo Starr (born Richard Starkey), drummer with another popular Merseyside outfit, Rory Storm the Hurricanes. Starr had been in the Beatles for a few weeks when they preserve their first genius, sleep together Me Do/P.S. I Love You, in family line 1962. Both sides of the 45 were Lennon-McCartney originals, and the telephone callwriting team would be credited with most of the groups material throughout the Beatles career.The champion, a promising but fairly rudimentary effort, hovered around the lower reaches of the British Top 20. The Beatles phenomenon didnt truly kick in until Please Please Me, which go past the British charts in early 1963. This was the prototype British Invasion single an infectious melody, charging guitars, and positively exuberant harmonies. The same traits were evident on their ternion 45, From Me to You (a British pattern one), and their debut LP, Please Please Me. Although it was mostly save in a single day, Please Please Me topped the British charts for an astonishing 30 weeks, establishing the group as the most popular rock roll act ever seen in the U.K.What the Beatles had done was to take the best elements of the rock and pop they loved and make them their own. Since the Quarrymen days, they had been steeped in the classic early rock of Elvis, Buddy Holly, Chuck Berry, Little Richard, Carl Perkins, and the Everly Brothers theyd also kept an ear open to the early 60s sounds of Motown, Phil Spector, and the girl groups. What they added was an unmatched songwriting savvy, a brash guitar-oriented attack, wildly enthusiastic vocals, and the embodiment of the offspringful flair of their generation, ready to dispense with postwar austerity and claim a culture of their own.They were also unsurpassed in their eclecticism, willing to borrow from blues, popular standards, gospel, folk, or whatever seemed suitable for their musical vision. Producer George Martin was the perfect foil for the group, refining their ideas without tinkering with their cores during the weather half of their career, he was indispensable for his ability to tra nslate their concepts into arrangements that required complex orchestration, innovative applications of recording technology, and an ever-widening array of instruments.Just as crucially, the Beatles were never ones to stand still and milk formulas. All of their subsequent record phonograph albums and single would show remarkable artistic progression. Even on their second LP, With the Beatles (1963), it was evident that their talents as composers and instrumentalists were expanding furiously, as they devised ever more inventive melodies and harmonies, and boosted the fullness of their arrangements. She Loves You and I hope to Hold Your Hand established the group not just as a popular music act, but as a phenomenon never before seen in the British entertainment business, as each single sold over a million copies in the U.K. After some celebrated national TV appearances, Beatlemania broke out across the British Isles in late 1963, the group generating screams and hysteria at all o f their public appearances, musical or otherwise.Capitol, which had first refusal of the Beatles recordings in the United States, had declined to issue the groups first few single, which ended up appearing on relatively small American independents. Capitol took up its survival on I Want to Hold Your Hand, which stormed to the top of the U.S. charts within weeks of its release on December 26, 1963. The Beatles tv appearances on The Ed Sullivan Show in February of 1964 launched Beatlemania (and the entire British Invasion) on an even bigger scale than it had reached in Britain.In the first week of April 1964, the Beatles had the Top Five best-selling singles in the U.S. they also had the first two slots on the album charts, as well as other entries throughout the Billboard Top 100. No one had ever dominated the market for popular music so heavily its doubtful that anyone ever will again. The Beatles themselves would continue to reach number one with most of their singles and albums until their 1970 breakup. catchy as it may be to believe today, the Beatles were often dismissed by cultural commentators of the time as nothing more than a fad that would vanish within months as the novelty wore off. (Turkalo, 1990)The group ensured this wouldnt happen by making A Hard Days Night in early 1964, a cinma vrit-style motion picture comedy/musical that cemented their image as the mythical Four happy-go-lucky, individualistic, cheeky, funny lads with nonstop energy. The soundtrack was also a triumph, consisting entirely of Lennon-McCartney tunes, including such standards as the title tune, And I Love Her, If I Fell, Cant sully Me Love, and Things We Said Today. George Harrisons resonant 12-string electric automobile guitar gratuitys were hugely influential the movie helped channel the Byrds, then folk singers, to plunge full-scale into rock roll, and the Beatles (along with Bob Dylan) would be hugely influential on the folk-rock explosion of 1965. The Beatles succ ess, too, had begun to open the U.S. market for logger Brits like the Rolling Stones, the Animals, and the Kinks, and elysian young American groups like the blighter Brummels, Lovin Spoonful, and others to mount a challenge of their own with self-penned material that owed a great debt to Lennon-McCartney.SignificanceBetween riotous international tours in 1964 and 1965, the Beatles continued to abbreviate out more chart-topping albums and singles. In retrospect, critics have judged Beatles for Sale (late 1964) and Help (mid-1965) as the bands least impressive efforts. To some degree, thats true. Touring and an insatiable market placed backbreaking demands upon their songwriting, and some of the originals and covers on these records, while brilliant by many groups standards, were filler in the context of the Beatles best work.But when at the top of their game, the group was continuing to push forward. I Feel Fine had feedback and brilliant guitar leads slating to Ride showed t he band beginning to incorporate the ringing, metallic, circular guitar lines that would be appropriated by bands like the Byrds Help was their first burst of confessional lyricism Yesterday utilise a string quartet. John Lennon in finical was beginning to display a Dylanesque influence in his songwriting on such folky, downbeat numbers as Im a Loser and Youve Got to Hide Your Love Away. And tracks like I Dont Want to Spoil the Party and Ive Just Seen a Face had a fuddled country flavor.Although the Beatles second film, Help, was a much sillier and less sophisticated affair than their first feature, it too was a huge mercenary success. By this time, though, the Beatles had nothing to prove in commercial terms the remaining frontiers were artistic challenges that could only be met in the studio. (Jansen, 2000)They rose to the occasion at the end of 1965 with Rubber Soul, one of the classic folk-rock records. Lyrically, Lennon, McCartney, and even Harrison were evolving beyond bo y-girl scenarios into complex, personal feelings. They were also move the limits of studio rock by devising saucy guitar and bass textures, experimenting with distortion and multi-tracking, and using unconventional instruments like the sitar.As much of a progression as Rubber Soul was relative to their previous records, it was but a taster for the boundary-shattering outings of the next few years. The Paperback Writer/ rain down single found the group abandoning wild-eyed topics entirely, boosting the bass to previously little-known levels, and fooling around with psychedelic imagery and backwards tapes on the B-side. Drugs were render their already fertile imaginations, but they felt creatively hindered by their touring obligations. Revolver, released in the summer of 1966, proved what the group could be capable of when allotted months of time in the studio.Hazy hard guitars and thicker vocal arrangements formed the bed of these increasingly imagistic, ambitious lyrics the gr oups eclecticism now encompassed everything from singalong novelties (Yellow Submarine) and string quartet-backed character sketches (Eleanor Rigby) to Indian-influenced swirls of come back and backwards tapes (Tomorrow Never Knows). somewhat would complain that the Beatles had abandoned the earthy rock of their roots for clever mannerism. But Revolver, like virtually all of the groups singles and albums from She Loves You on, would be a worldwide chart-topper.InfluenceFor the past couple of years, live mental process had become a rote exercise for the group, tired of competing with thousands of hollo fans that drowned out most of their voices and instruments. A 1966 summer worldwide tour was curiously grueling the groups entourage was physically attacked in the Philippines after a perceive snub of the countrys queen, and a casual remark by John Lennon about the Beatles being bigger than Jesus Christ was picked up in the States, resulting in the burning of Beatle records in t he Bible belt and demands for a repentant apology. Their net contrive of that American tour (in San Francisco on August 29, 1966) would be their finis in front of a paying audience, as the group inflexible to stop playing live in run to concentrate on their studio recordings.This was a radical and unprecedented step in 1966, and the media was overriding with speculation that the act was breaking up, especially after all quartette spent late 1966 engaged in separate personal and artistic pursuits. The appearance of the Penny Lane/Strawberry Fields Forever single in February 1967 squelched these concerns. Frequently cited as the strongest double A-side ever, the Beatles were now pushing forward into unabashedly psychedelic territory in their use of orchestral arrangements and Mellotron, without abandoning their grasp of memorable melody and immediately accessible lyrical messages.Sgt. Pepper, released in June 1967 as the Summer of Love dawned, was the definitive psychedelic soun dtrack. Or, at least, so it was perceived at the time subsequent critics have painted the album as an uneven affair, given a conceptual unity via its brilliant multi-tracked overdubs, singalong melodies, and fairy tale-ish lyrics. Others remain convinced, as millions did at the time, that it represented pops sterling(prenominal) triumph, or indeed an evolution of pop into art with a capital A.In addition to mining all manner of roots influences, the musicians were also picking up vibes from Indian music, avant-garde electronics, classical, music hall, and more. When the Beatles premiered their hipster anthem All You Need Is Love as part of a worldwide TV broadcast, they had been truly anointed as spokespersons for their generation , and it seemed they could do no wrong. (Jansen, 2000)Musically, that would usually continue to be the case, but the groups strength began to unravel at a surprisingly quick pace. In August 1967, Brian Epstein prone to suicidal depression over the past year died of a drug overdose, passing them without a manager. The group pressed on with their next film project, magic Mystery Tour, directed by themselves lacking focus or even basic professionalism, the picture bombed when it was premiered on BBC television in December 1967, great(p) the media the first real chance theyd ever had to roast the Beatles over a flame. In early 1968, the Beatles decamped to India for a course in transcendental meditation with the Maharishi this too became something of a media embarrassment, as each of the four would eventually set out the course before its completion.The Beatles did use their unaccustomed peace in India to compose a wealth of new material. Judged solely on musical merit, The snow-white Album, a double LP released in late 1968, was a triumph. While largely abandoning their psychedelic instruments to return to guitar-based rock, they maintained their whimsical eclecticism, proving themselves masters of everything from blues-rock to vaudeville. As individual songwriters, too, it contains some of their finest work (as does the brilliant non-LP single from this era, Hey Jude/ renewal).The problem, at least in terms of the groups long-term health, was that these were very much individual songs, as debate to corporate ones. Lennon and McCartney had long composed most of their tunes separately (you can or so always tell the composer by the lead vocalist). But they had always supply off of each other not only to supply wanting bits and pieces that would bring a song to completion, but to provide a war-ridden edge that would bring out the best in the other. McCartneys romantic melodicism and Lennons more acidic, gritty wit were perfect complements for one another. By the White Album, it was pass that each member was more concerned with his own expression than that of the collective group a natural impulse, but one that was bound to lead to difficulties.In addition, George Harrison was becoming a more prolif ic and skilled composer as well, imbuing his own melodies (which were nearly the equal of those of his more celebrated colleagues) with a cosmic lightness. Harrison was beginning to resent his junior status, and the group began to bicker more openly in the studio. Ringo Starr, whose solid drumming and good nature could usually be counted upon (as was evident in his infrequent lead vocals), actually quit for a couple of weeks in the midst of the White Album sessions (though the media was unwitting of this at the time). Personal interests were coming into play as well Lennons devotion to romantic and artistic pursuits with his new girlfriend Yoko Ono was diverting his attentions from the Beatles. Apple Records, started by the group earlier in 1968 as a sort of utopian commercial enterprise, was becoming a financial and organisational nightmare.These werent the i have sex conditions under which to record a new album in January 1969, especially when McCartney was pushing the group to r eturn to live do, although none of the others seemed especially keen on the idea. They did agree to try and record a back-to-basics, live-in-the-studio-type LP, the sessions being filmed for a television special. That intent almost blew up when Harrison, in the midst of tense arguments, left the group for a few days. Although he returned, the idea of playing live concerts was repose on the back burner Harrison enlisted American soul keyboardist Billy Preston as signifier of a fifth member on the sessions, both to beef up the arrangements and to alleviate the uncomfortable atmosphere.Exacerbating the problem was that the Beatles didnt have a great deal of first-class new songs to work with, although some were excellent. In order to provide a suitable concert-like experience for the film, the group did climb the capital of their Apple headquarters in London to deliver an impromptu performance on January 30, 1969, before the police stopped it this was their lead live concert of a ny sort. (Jansen, 2000)Generally dissatisfied with these early-1969 sessions, the album and film at first titled Get Back, and later to emerge as let It Be remained in the can as the group tried to figure out how the projects should be mixed, packaged, and distributed. A couple of the best tracks, Get Back/Dont Let Me Down, were issued as a single in the spring of 1969. By this time, the Beatles quarrels were increase in a dispute over management McCartney wanted their personal matters to be handled by his new father-in-law, Lee Eastman, while the other members of the group favored a tough American businessman, Allen Klein.It was something of a miracle, then, that the final album recorded by the group, Abbey Road, was one of their most unified efforts. It certainly boasted some of their most intricate melodies, harmonies, and instrumental arrangements it also heralded the arrival of Harrison as a composer of equal talent to Lennon and McCartney, as George wrote the albums two mo st popular tunes, Something and Here make loves the Sun. The Beatles were still progressing, but it turned out to be the end of the road, as their business disputes continued to magnify. Lennon, who had begun releasing unaccompanied singles and performing with friends as the Plastic Ono Band, peril to resign in late 1969, although he was dissuaded from making a public announcement.Most of the early-1969 tapes remained unreleased, partially because the footage for the planned television broadcast of these sessions was now leaving to be produced as a objective movie. The accompanying soundtrack album, Let It Be, was delayed so that its release could coincide with that of the film. Lennon, Harrison, and Allen Klein headstrong to have celebrated American producer Phil Spector record some surplus instrumentation and do some mixing. Thus the confusion that persists among most rock listeners to this day Let It Be, although the last Beatles album to be released, was not the last one to be recorded. Abbey Road should actually be considered as the Beatles last album most of the material on Let It Be, including the title track (which would be the last single released while the group was still together), was recorded several months before the Abbey Road sessions began in earnest, and a good 15 months or so before its May 1970 release.By that time, the Beatles were no more. In fact, there had been no recording done by the group as a unit since August 1969, and each member of the band had begun to conform to serious outside professional interests independently via the Plastic Ono Band, Harrisons tour with Delaney Bonnie, Starrs have role in the Magic Christian film, or McCartneys first solo album. The outside world for the most part remained almost wholly unaware of the seriousness of the groups friction, making it a devastating shock for much of the worlds youth when McCartney announced that he was leaving the Beatles on April 10, 1970.The final blow, apparentl y, was the conflict amidst the release dates of Let It Be and McCartneys debut solo album. The rest of the group asked McCartney to delay his release until after Let It Be McCartney refused, and for good measure, was broken by Spectors post-production work on Let It Be, particularly the string overdubs on The Long and Winding Road, which became a posthumous Beatles single that spring. Although McCartney received much of the blame for the binge, it should be remembered that he had done more than any other member to keep the group going since Epsteins death, and that each of the other Beatles had threatened to leave well before McCartneys departure. With hindsight, the breakup seemed inevitable in cipher of their serious business disagreements and the growth of their individual interests.As bitter as the initial headlines were to swallow, the controversying would grow much worse over the next few years. At the end of 1970, McCartney sued the rest of the Beatles in order to dissol ve their fusion the battle dragged through the courts for years, scotching any prospects of a group reunion. In any case, each member of the band quickly established viable solo careers. In fact, at the outset it could have been argued that the artistic effects of the split were in some ways beneficial, freeing Lennon and Harrison to make their most harsh artistic statements (Plastic Ono Band and All Things Must Pass). Georges individual talents in particular received acclaim that had always eluded him when he was overshadowed by Lennon-McCartney.Paul had a much rougher time with the critics, but continued to issue a electric current of hit singles, hitting a commercial and unfavourable jackpot at the end of 1973 with the massively successful Band on the Run. Ringo did not have the songwriting acumen to compete on the same level as the others, soon enough he too had quite a few big hit singles in the early 70s, often benefiting from the assistance of his former band-mates. mere ly within a short time, it became apparent both that the Beatles were not going to settle their differences and reunite, and that their solo work could not compare with what they were capable of creating together. The assort has it that the split allowed each of them to indulge in their worst tendencies to their extremes Lennon in agit-prop, Harrison in holier-than-thou-mysticism, McCartney in cutesy pop, Starr in easy listening rock. Theres a good deal of truth in this, but its also important to bear in mind that what was most missing was a sense of group interaction. The critical party line often champions Lennon as the angry, realist rocker, and McCartney as the melodic balladeer, but this is a fallacy each of them were capable, in roughly equal measures, of ballsy all-out rock and sweet romanticism. What is not in dispute is that they sparked each other to reach heights that they could not attain on their own.Despite occasional rumours of reunions throughout the 1970s, no group projects came close to materializing. It should be added that the Beatles themselves continued to feud to some degree, and from all evidence werent seriously interested in work together as a unit. Any hopes of a reunion vanished when Lennon was assassinate in New York City in December 1980. The Beatles continued their solo careers throughout the 1980s, but their releases became less frequent, and their commercial success gradually diminished, as listeners without first-hand memories of the combo created their own idols.The popularity of the Beatles-as-unit, however, proved eternal. In part, this is because the groups 1970 split effectively short-circuited the prospects of artistic decline the body of work that was preserved was uniformly strong. However, its also because, like any great works of art, the Beatles records carried an ageless magnificence that continues to captivate new generations of listeners. So it is that Beatles records continue to be heard on radio in heavy rota tion, continue to sell in massive quantities, and continue to be covered and quoted by rock and pop artists through the present day. statutory wrangles at Apple prevented the official issue of previously unreleased Beatle material for over two decades (although much of it was frequently bootlegged). The situation finally changed in the 1990s, after McCartney, Harrison, Starr, and Lennons widow Yoko Ono settled their principal business disagreements. In 1994, this resulted in a double CD of BBC sessions from the early and mid-60s. The following year, a much more ambitious project was undertaken a multi-part film documentary, broadcast on network television in 1995, and then released (with double the length) for the home image market in 1996, with the active participation of the surviving Beatles.To coincide with the Anthology documentary, three double CDs of previously unreleased/rare material were issued in 1995 and 1996. Additionally, McCartney, Harrison, and Starr (with some assi stance from Jeff Lynne) embellished a couple of John Lennon demos from the 1970s with overdubs to create two new tracks (Free as a Bird and Real Love) that were billed as actual Beatles recordings. Whether this constitutes the actual long-awaited reunion is the subject of much debate.Certainly these cuts were merely classics on par with the music the group made in the 1960s. Some fans, even diehards, were inclined to view the whole Anthology project as a distinctly 1990s marketing exercise that maximized the mileage of whatever could be squeezed from the Beatles vaults. If nothing else, though, the massive commercial success of outtakes that had, after all, been recorded 25 to 30 years ago, spoke volumes about the unabated appeal and captivation the Beatles continue to exert worldwide.Revolution song AnalysisRevolution is a song by The Beatles, written primarily by John Lennon and attributed to Lennon-McCartney. The song appeared in two distinctly different incarnations, a raucous electric Revolution, and a slowed acoustic Revolution 1. A third connected piece, the heavily experimental Revolution 9, appeared on the same album side (i.e., side 4) as Revolution 1 on The White Album. (Corliss, 2004)Lennon claimed the song was inspired by the May 1968 uprising in France. Another song called Revolution was released by the London psychedelic group Tomorrow in September 1967, a year before the John Lennon song. Tomorrows lyric Have your own little variety, NOW contrasts with Lennons lyric, including the opening lines, You say you want a revolution/ Well, you know/ We all want to change the world.There is a dogma that in some studio versions of the song, the pronunciation of evolution early in the song has what sounds like an overdubbed voice distorting evolution into what sounds eerily similar to evil-jew-shin. A common myth is that Lennon wrote the track in disdain of overwhelming money-hungry businessmen. This theme of anti-semitism is not alone in this song, a s in Come Together the verse verse can be interpreted as describing a hasidic jew.Revolution 9 is an experimental recording which appeared on the Beatles 1968 self-titled LP release (known as the White Album). The track marked the peak of the bands studio experimentation the inclusion of such a sound collage or musique concrte on a pop music release was virtually unprecedented. The recording began as an extended ending to the album version of Revolution, to which were added vocal and music sound clips, tape loops, and sound effects influenced by t
