Loss of Biodiversity free essay sample

The definition of biodiversity encompasses the degree of variations in organisms and/ or species within an ecosystem. The loss of biodeversity would be the diminishing of dfferent species within that ecosystem. For example, a lake may be the home to many types of fish. A change in the lakes temperature or chemistry may affect a food source for a certain type of fish. This type of fish may die out and leave the lake with one less species in it. The loss of one fish or food source may impact other populations and furthe diminish species diversity. Cause Invasive Species plants or animals which have moved to a habitat where they were not naturally found and are more successful than local species. Habitat loss Agriculture, housing and industry are destroying the habitats of many plants, animals and microbes. Our development means we must destory or decrease the natural ecosystems. Many animals have a certain range that they must maintain in order to live.

Pollution Our oceans, rivers, lakes and lands have become rubbish bins for societys industrial and organic waste. Plastic in our garbage causes enormous problems. It kills or injures many marine animals and birds either through accidental entanglement or ingestion of the material in the mistaken belief that the plastic is food. For example, sometimes bags are misidentified as jellyfish. Climate Change Many plant and animal species are unlikely to survive climate change. For some species there will no longer be anywhere to live. Exploitation We have drastically reduced some fish populations, hunted some whales to the verge of extinction and destroyed whole forests and their ecosystems. Blast fishing is another practise which reduces the coral reefs in the sea. It is practiced in many areas. This is the process whereby dynamite is placed into an area in order to catch a large quantity of fish. Coral reefs especially are devastated by this activity. It is most prominent in undeveloped countries where this practice has existed for years. Effect The ecosystems deteriorate to an unsustainable level, at which the results would be incredibly expensive to reverse (ex. in Bangladesh and India, the over-logging of trees and forests makes floods during the monsoon seasons deadly. environmental changes Loss of one species may cause a chain reaction, resulting in a change to the ecosystem itself. gives us less choice as humans If certain species are lost, they are no longer available to us either as food, as enjoyment, or as resources for things we may not even know about yet. For example, if we deplete all the yellowfin tuna in the ocean, we no longer have this species avail able for our consumption. If we are divers or underwater explorers, we no longer can see this fish in its own environment and receive pleasure from this act. Solution Stop climate change from running out of control. In order to tackle climate change world needs international climate deal that would reduce greenhouse gas emissions on global level. Stop deforestation. Tropical rainforests are the areas of the richest biodiversity in our planet, providing living environment for millions of different species. Reduce environmental pollution. Pollution is not only happening in land but also in our oceans having very negative impact on marine biodiversity. Animals and plants cant thrive in polluted environment. Education and the Media Through educating people about the severity of this issue, there will be (hopefully) less exploitations of resources, pollution, and habitat losses. In addition, the media could be used to spread these types of thoughts and again, emphasize the importance of biodiversity, the detrimental effects it has on ecosystems, and how it impacts us. Biodiversity also needs to be more studied in order to give us the necessary knowledge needed to protect animal and plant species from going extinct.

The Nurture Of Gender Roles

The Nurture Of Gender Roles The ideas and expectations of men and women in American society are established and secure in the nation's mind. More women stay home during the day to take care of the house and children than men, and more men hold political offices than women. These traditional gender roles are the way of life in America, and rarely ever opposed. However, did you ever stop to think about why you associate cooking with women or leadership with men? Was there ever a time you did not feel this way? Surely, you must have learned these values at some point, and most likely when at a young age. Images of the stereotypical housewife and bread-winning husband are constantly being flashed on the television. Commercials, news programs, and even cartoons illustrate a male dominated society. During prime-time television men outnumber women two or three to one. Television not only feeds the principle of stereotypical gender roles, but also reinforces it with every change of the program, showing the same images of men and women.American Academy of PediatricsWith the average American watching at least 3 hours of television a day, the standard is set in our minds.The mind is more easily influenced during childhood, while development is still taking place. Information gathered during this stage will settle much longer than in adults. Dr. Nancy Signorielli stated in the official news magazine for the American Academy of Pediatrics (AAP News) "Television plays a central role in most youngsters' social lives". The media is a major part

The History of the Italian Language

The History of the Italian Language You’re always hearing that Italian is a romance language, and that’s because linguistically speaking, it’s a member of the Romance group of the Italic subfamily of the Indo-European family of languages. It is spoken principally in the Italian peninsula, southern Switzerland, San Marino, Sicily, Corsica, northern Sardinia, and on the northeastern shore of the Adriatic Sea, as well as in North and South America. Like the other Romance languages, Italian is a direct offspring of the Latin spoken by the Romans and imposed by them on the peoples under their dominion. However, Italian is unique in that of all the major Romance languages, it retains the closest resemblance to Latin. Nowadays, it’s considered one language with many different dialects. Development During the long period of Italian’s evolution, many dialects sprang up, and the multiplicity of these dialects and their claims upon their native speakers as pure Italian speech presented a peculiar difficulty in choosing a version that would reflect the cultural unity of the entire peninsula. Even the earliest popular Italian documents, produced in the 10th century, are dialectal in language, and during the following three centuries Italian writers wrote in their native dialects, producing a number of competing regional schools of literature. During the 14th century, the Tuscan dialect began to dominate. This may have happened because of Tuscany’s central position in Italy and because of the aggressive commerce of its most important city, Florence. Moreover, of all the Italian dialects, Tuscan has the greatest similarity in morphology and phonology from classical Latin, which makes it harmonize best with the Italian traditions of Latin culture. Finally, Florentine culture produced the three literary artists who best summarized Italian thought and feeling of the late Middle Ages and the early Renaissance: Dante, Petrarca, and Boccaccio. The First 13th Century Texts In the first half of the 13th century, Florence was preoccupied with the development of trade. Then interest began to broaden, especially under the lively influence of Latini. Brunetto Latini (1220-94): Latini was exiled to Paris from 1260 to 1266 and became a link between France and Tuscany. He wrote the Trà ¨sor (in French) and the Tesoretto (in Italian) and contributed to the development of allegorical and didactic poetry, along with a tradition of rhetoric upon which dolce stil nuovo and Divine Comedy were based.The dolce stil nuovo (1270-1310): Although in theory they continued the Provenà §al tradition and counted themselves members of the Sicilian School of Federico IIs reign, the Florentine writers went their own way. They used all their knowledge of science and philosophy in a delicate and detailed analysis of love. Among them were Guido Cavalcanti and the young Dante.The Chroniclers: These were men of the merchant class whose involvement in city affairs inspired them to write tales in the vulgar tongue. Some, such as Dino Compagni (d. 1324), wrote about local conflicts and rivalries; others, like Giovanni Villani (d. 1348), took on much wider E uropean events as their subject. The Three Jewels in the Crown Dante Alighieri (1265-1321): Dantes Divine Comedy is one of the great works of world literature, and it was also proof that in literature the vulgar tongue could rival Latin. He had already defended his argument in two unfinished treatises, De vulgari eloquentia and Convivio, but to prove his point it needed the Divine Comedy, this masterpiece in which Italians rediscovered their language in sublime form (Bruno Migliorini).Petrarch (1304-74): Francesco Petrarca was born in Arezzo since his father was in exile from Florence. He was a passionate admirer of ancient Roman civilization and one of the great early Renaissance humanists, creating a Republic of Letters. His philological work was highly respected, as were his translations from Latin into the Vulgate, and also his Latin works. But it’s Petrarchs love poetry, written in the vulgar tongue, that keeps his name alive today. His Canzoniere had enormous influence on the poets of the 15th and 16th centuries.Boccaccio (1313-75): This was a man from the rising commercial classes, whose principal work, ​​Decameron, has been described as a merchants epic. It consists of one hundred stories told by characters who are also part of a story that provides the setting for the whole, much like The Arabian Nights. The work was to become a model for fiction and prose writing. Boccaccio was the first to write a commentary on Dante, and he was also a friend and disciple of Petrarch. Around him gathered enthusiasts of the new humanism. La Questione Della Lingua The question of the language, an attempt to establish linguistic norms and codify the language, engrossed writers of all persuasions. Grammarians during the 15th and the 16th centuries attempted to confer upon the pronunciation, syntax, and vocabulary of 14th-century Tuscan the status of a central and classical Italian speech. Eventually, this classicism, which might have made Italian another dead language, was widened to include the organic changes inevitable in a living tongue. In the dictionaries and publications of the, founded in 1583, which was accepted by Italians as authoritative in Italian linguistic matters, compromises between classical purism and living Tuscan usage were successfully effected. The most important literary event of the 16th century did not take place in Florence. In 1525 the Venetian Pietro Bembo (1470-1547) set out his proposals (Prose della volgar lingua - 1525) for a standardized language and style: Petrarca and Boccaccio were his models and thus became the modern classics. Therefore, the language of Italian literature is modeled on Florence in the 15th century. Modern Italian It wasn’t until the 19th century that the language spoken by educated Tuscans spread far enough to become the language of the new nation. The unification of Italy in 1861 had a profound impact not only on the political scene but also resulted in a significant social, economic, and cultural transformation. With mandatory schooling, the literacy rate increased, and many speakers abandoned their native dialect in favor of the national language.

Applied theory Essay Example | Topics and Well Written Essays - 1500 words

Applied theory - Essay Example Besides Beyonce and her husband Jay Z, the article talks about other popular bands such as U2 and its lead singer Bono and Coldplay, the major artists expected to perform at the summer music festival in Glastonbury (Topping, 2011: 15). From this article, the emergence of the popular culture in form of music can be evaluated by considering theories of industrialization and of cultural studies. Popular culture is a broad term that incorporates common aesthetic or life practices in qualitative and statistical dimensions (Arnold, 1964:31). However, modern day theorists regard popular culture as a common tradition that has arisen in the modern times and it differs from folk tradition because it is mass-produced and different from high life because it is consumed in mass (Arnold, 1964:32). From this article on Beyonce, it is apparent that popular culture has undergone a lot of transformation from the last century. The current popular culture is characterized by extensive use of the mass me dia to publicize the events and elaborate organization by the artist and event organizers. Gans (1974:61-62) defines popular culture as an epitome of the society, reflecting the transformations occurring in the society. According to Giddens (1979:29), European and American societies underwent profound transformation in the 18th and 19th centuries. These changes resulted to massive social reorganization especially in the western European spheres where many people moved to work in urban areas in the emerging industries. Transformation from the rural peasantry to mass production in industries not only influenced the economic aspect of the workers, but their culture took a different turn (Giddens, 1979:49). Arnold (1964:85) noted that industrialization also brought with it capitalism in addition to increased interactions and mixing of diverse cultures. A combination of these factors in addition to the strenuous activities in the industries resulted to creation of a homogeneous society, with shared experiences across the regions. In addition, the increasing social density in the community and division of labor due to capitalism accelerated creation of distinct social classes, especially at the middle class level. Archer (1995:116-125) argues that a combination of capitalism ideology and its austere administrative structure resulted to increasing literacy levels especially to the middle class creating a formidable social, economic and cultural hegemony that changed the popular culture immensely. In this regard, capitalism resulted to sudden change in power that eventually caused social differentiation in the society. Archer (1995: 19) argues that the raise of the popular culture does not only involve a large group of individuals, but people who have high level of organization pertaining to their tastes and preferences. This class plays a very critical role in the cultural industry that has developed to meet the artistic aspirations of the middle class. Another influ ential factor in the middle class towards the popular culture is the high literate levels. According to Archer (1995: 49), the increasing levels of literacy in the middle class resulted to more economic empowerment that lead to accelerated social differentiation that enabled the people to realize new possibilities and discover new and limitless dimensions of their lives for exploration. Therefore, the middle class did not wish to be just machines working in the emerging industries for survival, but as beings with another dimension for fun and recreation. The high culture was not initially intended for entertainment, but it provided the middle class with opportunities for expressing their frustrations, achievements, joys and aspirations in their working places. Burke, (1978 b: 113) noted that the emergence of the

Human Service Agencies Essay Example for Free

Human Service Agencies Essay Human service agencies are formed by and for the public. As communities grow and change, the need to respond to the demands of these dynamic societies also increases. Not only does the society lay itself open to positive opportunities, it is also exposed to the negative drawbacks of this dynamism. In fact, there are so many social issues that individuals alone cannot resolve. These are matters concerning the society that need sufficient and appropriate attention also from the society. These agencies do serve as intermediaries between solutions to problems and individuals, families, and societies. There are many issues that individuals, families and societies have that need communal action. I believe that these important issues include the most rampant problems nowadays encountered by people. Even the simplest problems like underage alcoholism, drug dependence, compulsive gambling, widespread crimes†¦ these are social issues that need immediate attention. Issues starting in individuals or within families also necessitate consideration. Some of these are problems of child and women abuse, violence within and outside families, severe and persistent illnesses, including contagious ones, severe emotional disturbances experienced by people, and the like. I think, these ‘simple’ matters must be acted upon immediately by service organizations like human service agencies. This is to mediate and assure proper assistance to individuals and families, thereby assuring their safety, peacefulness, health and wellness, and the society’s as well. I also believe that there are no least important issues, as long as individuals or families, or members of the society are involved, they are considered issues that must be resolved†¦ immediately. I arrived at this standpoint because I myself am a member of this society. Directly or indirectly, I rely and I may rely in the future in these human service agencies for betterment, improvement, protection and the like. And I must not be concerned only about myself but also about the welfare of the whole society.

Frankenstein And Schizoprenia (My Teacher LOVED This Paper) :: essays research papers fc

Schizophrenia and Frankenstein In a psychoanalytic view of Mary Shelley’s Frankenstein, Robert Walton develops, during a â€Å"dreadfully severe† trip through the Arctic, a type of schizophrenia; this mental condition enables him to create a seemingly physical being representing each his superego and his id (9). In his mind, Walton creates Victor as his very own superego and the monster as his id. The superego and the id battle throughout the story to produce the final result: Walton, the ego. Many of the qualities Walton develops during his trip are symptoms of schizophrenia. His letters exude an aura of depression, loneliness, In his second letter, Walton emphasizes an obsession with his aspiration to lose his loneliness. He â€Å"desires the company of a man who could sympathize with [him]† (Shelley 7). According to Merrell Dow, Preoccupations†¦are fixed ideas, not necessarily false (like delusions) but overvalued. They take on extraordinary importance and take up an ordinate amount of thought time. One idea often returns and returns†¦Characteristically, the worry grows and becomes unrealistic (par 16). Walton reiterates his loneliness; even though he is surrounded by people on his ship, he â€Å"[has] no friend† (Shelley 7-8). Contributing to this feeling of isolation, Walton uses a tone of depression in his letters, a recurring feeling he experiences. He hints in nearly every letter clues indicating his fear of death. He wants his sister to â€Å"remember [him] with affection; should [she] never hear from [him] again† (Shelley 10). By constantly mentioning the possibility of his own death in his letters, Shelley stresses Walton’s overvalued worry of dying. Walton longs to see his sister; his mental condition leads him to even consider himself abandoned. Walton admits that success during this mission will lead to â€Å"many, many months, perhaps years† before they would meet again; however, failure results in either quick departure for home, or death (Shelley 6). Whether he succeeds or fails, he will have negative results. These constant recurrences emph asize the validity of his mental illness. As he develops the mental disease, Walton creates a world that makes sense in his mind, and his mind alone; he â€Å"[lives] in a Paradise of [his] own creation† with characters whom spawn from his own psyche (Shelley 5). Once schizophrenia becomes severe, Walton develops two seemingly real characters in his imagination. Walton’s mental condition and obsessive longing for someone to connect with leads him to separate himself mentally from his superego and id.

Education, Teaching and Curriculum Essay

Education has always been an important aspect in the course of personal and societal development as a whole. Every individual has an urge and personal willingness to learn valuable information that varies from either practical knowledge o scientific ones. However, all of these relevant informations are very much needed by every individual to be able to develop their own self and become self-sufficient and productive members of the society. Education has many methodologies from which one individual can attain it in a scientifically formulated pattern. This is actually the main pattern accepted and utilized by all educational institution in their formal learning process and even implemented by those who implement informal ones. Gradual and progressive pattern is the most effective and easiest way used in learning process because it mainly accommodates normal brain development and innate learning abilities of the person. In this learning process, the main methodology commonly used in the per curriculum basis encompassing teaching instructions for learning individuals. Curriculum is literally defined in education as a set of courses regarding different classes or subjects offered in different educational institutions such as a school or a university. Embedded in its process are different specific classes for minor and major aspects that are all conjoined in adherence to the course objective of the entire curriculum. This is actually formulated and expressed in terms of its learning outcomes and for the development of the students taking up the said curriculum. Curriculums in general, whatever its subject or class is, are all created to envelope the learning process of individuals learning their specific course to develop and acquire valuable and relevant skills in that specific field. The main learning approach commonly used in the curriculum teaching is based on a set of instruction, which are all directed to guide the students in the gradually process of learning in the curriculum. Instructions are a basic aspect of the learning process. They are all formulated to guide students in their gradual learning process in their respective fields. In educational curriculum, instructions serve as a form of communicated information that has a command and explanation nature. Thus, instructions are descriptive explanations for how an action, behavior, method, or task is to be begun, completed, conducted, or executed. Because of their significant relevance to the learning process of individuals, instructions are explicitly used in the approach system and learning process in a curriculum. Learning instructions are generally formulated and given to students to guide them in discovering and thus learning the different specific informations and processes that are significant in the execution and completion of their respective subjects that are enveloped in their curriculum. With consideration of the definition and significant or the two main aspects in the learning process, curriculum and instruction have a direct relationship with each other. In the education aspect, curriculums are generally composed of specific set of instructions in specific subjects based on its respective course. Instruction are formulated and applied by the educational institutions to guide and educate explain to their students the knowledge and information in the different subjects encompassed in the gradual learning process of their different curriculums in every courses or fields. Thus, curriculum and instructions go side-by-side in systematically developing and directing the educational system to better address the normal mental development and innate learning process of the students thus encouraging more productive and efficient learning approach for the society. In terms of the higher level of educational set up, the curriculums offered as well as the regulations are diversely changed to apply to the demands required for the learners. Obviously, the requirements of concentration and focus from the students are heightened. However, this does not add the directly instructional as compared to that of the lower levels of learning. Obviously, this is primarily because of the fact that the students in this level are already matured enough to be still instructed on what they are supposed to do. The students are rather expected to place higher concentration and intend to pursue in a better level of focus on the proper learning attitude needed for them to survive this particular stage of learning. The instance of being able to survive the scholastic challenges presented by the higher and more demanding environment of education is a primary achievement among those who are concentrating to attain the best out of their learning in this level of educational state. Most of the time, the students are known to be pressured in this set up, but all these procedures are strongly applied to actually help in the process of making the students see the real implications of their lessons in actual life.

Minimum Wage Increase Essay Essay

Most people would agree that raising the minimum wage sounds like a good idea, but arguments arise concerning if this increase would benefit the economy. Jared Bernstein believes that a minimum wage increase would positively affect the American economy. He argues that the economy is driven by consumer spending and low ­income workers are very likely to spend their extra earned money. On the contrary, Douglas Holtz ­Eakin strives to make the point that raising the minimum wage would not be beneficial to the economy. He argues that there would be no reduction in poverty because only a small percent of minimum wage workers are in poverty, while most are unemployed. An examination of raising the minimum wage will reveal why it will benefit American society. According to Jared Bernstein raising the minimum wage would help. Bernstine suggests that the American economy is made up of 70 percent consumer spending. He argues that an extra dollar earned by a wealthy person is less likely to be spent than an extra dollar earned by a low ­income person. In addition Bernstein points out that this leads to the low ­income worker being much more likely to consume their extra dollar of earnings. Similarly one might argue that a minimum wage increase that directly raises the pay of a relatively small share of the workforce by a small amount is unlikely to be a big deal. Raising the minimum wage is a growth strategy and should be used to try to revive our economy. The wage increase would help families struggling on minimum wage salaries. These families would see these new earni ngs as a chance to spend on new things and will slightly help macroeconomic growth. Helping the economy on the margin while also helping these families make ends meet. One should conclude that raising the minimum wage will help families in need and in terms help the economy. According to Douglas Holtz ­Eakin Raising the federal minimum wage will neither reduce poverty nor boost growth. Holtz ­Eakin suggests that increasing the minimum wage would ensure that m illions of Americans got raises that they would presumably turn right around and spend. He argues that unfortunately the money for a raise has to come out of the wallet of another American. In addition Holtz ­Eakin points out that the minimum wage hike for one low ­wage worker comes directly out of the pocket of another. In contrast one might suggest that the wage increase is neither anti ­poverty nor stimulus. According to Holtzs article companies may not be able to hire as many workers if the wage is increased. The money may not come directly from another working americans pocket but it has to come from somewhere. Businesses may suffer from the increase. Some businesses may not even be able to hire as many employees as necessary, taking away jobs. One should conclude that increasing the wage may harm other americans not directly affected by the increase. According to Jared bernstein the moderate increases in the minimum wage boost the earnings of most low ­wage workers without leading to large employment losses. He argues that The increase favored by the president and congressional Democrats, would place the real value of the wage floor back where it was in th e late 1960s. In addition Bernstein suggests that this increase would directly affect about 13 percent of the workforce. He argues a vast majority of low wage families would benefit from the increase. Similarly one might suggest that some families struggling to make ends meet have 2 or 3 minimum wage jobs. These families with multiple minimum wage jobs will greatly benefit from the increase. This research does not put into account that many families struggling on minimum wage have multiple minimum wage jobs. Now these families would have extra earnings to make ends meet and stimulate the economy. Since minimum wage workers are more likely to spend their extra dollars,the american economy will benefit from extra consumer spending. One should conclude that raising the minimum wage would help lower class families who depend on minimum wage. According to Douglas Holtz ­Eakin the minimum wage is a poor tool to fight poverty because it does not target those in poverty. Holtz ­Eakin suggests that only 2 percent of workers earn the minimum wage, and only 20 percent of those are in poverty. He argues that the reality is that the dividing line between being poor and being non ­poor is having a job. In addition Holtz ­Eakin points out that only 7 percent of those who have a job are in poverty, while more than 27.5 percent of those without jobs are poor.

Profile of The Beatles

Profile of The Beatles The Beatles were an English rock group that  shaped not only music but also an entire generation. With 20 songs that hit #1 on Billboards Hot 100 chart, the Beatles had a large  number of ultra-popular songs, including Hey Jude, Cant Buy Me Love, Help!, and Hard Days Night. The Beatles  style and innovative music set the standard for all musicians to follow. Dates: 1957 1970 Members: John Lennon, Paul McCartney, George Harrison, Ringo Starr (stage name of Richard Starkey) Also Known As Quarry Men, Johnny and the Moondogs, Silver Beetles, Beatals John and Paul Meet John Lennon and Paul McCartney first met on July 6, 1957, at a fete (fair) sponsored by St. Peters Parish Church in Woolton (a suburb of Liverpool), England. Although John was only 16, he had already formed a band called the Quarry Men, who were performing at the fete. Mutual friends introduced them after the show and Paul, who had just turned 15, wowed John with his guitar playing and ability to remember lyrics. Within a week of meeting, Paul had become part of the band. George, Stu, and Pete Join the Band In early 1958, Paul recognized talent in his friend George Harrison and the band asked him to join them. However, since John, Paul, and George all played guitars, they were still looking for someone to play bass guitar and/or the drums. In 1959, Stu Sutcliffe, an art student who couldnt play a lick, filled the position of bass guitarist and in 1960, Pete Best, who was popular with the girls, became the drummer. In the summer of 1960, the band was offered a two-month gig in Hamburg, Germany. Re-naming the Band It was also in 1960 that the Stu suggested a new name for the band. In honor of Buddy Hollys band, the Crickets- of whom Stu was a huge fan- he recommended the name of The Beetles. John changed the spelling of the name to Beatles as a pun for beat music, another name for rock n roll. In 1961, back in Hamburg, Stu quit the band and went back to studying art, so Paul took up the bass guitar. When the band (now only four members) returned to Liverpool, they had fans. The Beatles Sign a Record Contract In the fall of 1961, the Beatles signed a manager, Brian Epstein. Epstein succeeded in getting the band a record contract in March 1962. After hearing a few sample songs, George Martin, the producer, decided he liked the music but was even more enchanted with the boys witty humor. Martin signed the band to a one-year record contract but recommended a studio drummer for all recordings. John, Paul, and George used this as an excuse to fire Best and replace him with Ringo Starr. In September 1962, the Beatles recorded their first single. On one side of the record was the song Love Me Do and on the flip side, P.S. I Love You. Their first single was a success but it was their second, with the song Please Please Me, that made them their first number-one hit. By early 1963, their fame began to soar. After quickly recording a long album, the Beatles spent much of 1963 touring. The Beatles Go to America Although Beatlemania had overtaken Great Britain, the Beatles still had the challenge of the United States. Despite already having achieved one number-one hit in the U.S. and had been greeted by 5,000 screaming fans when they arrived at the New York airport, it was the Beatles February 9, 1964, appearance on The Ed Sullivan Show that ensured Beatlemania in America. Movies By 1964, the Beatles were making movies. Their first film, A Hard Days Night portrayed an average day in the life of the Beatles, most of which was running from chasing girls. The Beatles followed this with four additional movies: Help! (1965), Magical Mystery Tour (1967), Yellow Submarine (animated, 1968), and Let It Be (1970). The Beatles Start to Change By 1966, the Beatles were growing weary of their popularity. Plus, John caused an uproar when he was quoted as saying, Were more popular than Jesus now. The group, tired and worn out, decided to end their touring and solely record albums. About this same time, the Beatles began to shift to psychedelic influences. They started using marijuana and LSD and learning about Eastern thought. These influences shaped their Sgt. Pepper album. In August 1967, the Beatles received the terrible news of the sudden death of their manager, Brian Epstein, from an overdose. The Beatles never rebounded as a group after Epsteins death. The Beatles Break Up Many people blame Johns obsession with Yoko Ono and/or Pauls new love, Linda Eastman, as the reason for the bands break up. However, the band members had been growing apart for years. On August 20, 1969, the Beatles recorded together for the very last time and in 1970 the group officially dissolved. John, Paul, George, and Ringo went their separate ways. Unfortunately, John Lennons life was cut short when a deranged fan shot him on December 8, 1980. George Harrison died on November 29, 2001, from a long battle with throat cancer.

Example of Goodness of Fit Test

Example of Goodness of Fit Test The chi-square goodness of fit test is a useful to compare a theoretical model to observed data. This test is a type of the more general chi-square test. As with any topic in mathematics or statistics, it can be helpful to work through an example in order to understand what is happening, through an example of the chi-square goodness of fit test. Consider a standard package of milk chocolate MMs. There are six different colors: red, orange, yellow, green, blue and brown. Suppose that we are curious about the distribution of these colors and ask, do all six colors occur in equal proportion? This is the type of question that can be answered with a goodness of fit test. Setting We begin by noting the setting and why the goodness of fit test is appropriate. Our variable of color is categorical. There are six levels of this variable, corresponding to the six colors that are possible. We will assume that the MMs we count will be a simple random sample from the population of all MMs. Null and Alternative Hypotheses The null and alternative hypotheses for our goodness of fit test reflect the assumption that we are making about the population. Since we are testing whether the colors occur in equal proportions, our null hypothesis will be that all colors occur in the same proportion. More formally, if p1 is the population proportion of red candies, p2 is the population proportion of orange candies, and so on, then the null hypothesis is that p1 p2 . . . p6 1/6. The alternative hypothesis is that at least one of the population proportions is not equal to 1/6. Actual and Expected Counts The actual counts are the number of candies for each of the six colors. The expected count refers to what we would expect if the null hypothesis were true. We will let n be the size of our sample. The expected number of red candies is p1 n or n/6. In fact, for this example, the expected number of candies for each of the six colors is simply n times pi, or n/6. Chi-square Statistic for Goodness of Fit We will now calculate a chi-square statistic for a specific example. Suppose that we have a simple random sample of 600 MM candies with the following distribution: 212 of the candies are blue.147 of the candies are orange.103 of the candies are green.50 of the candies are red.46 of the candies are yellow.42 of the candies are brown. If the null hypothesis were true, then the expected counts for each of these colors would be (1/6) x 600 100. We now use this in our calculation of the chi-square statistic. We calculate the contribution to our statistic from each of the colors. Each is of the form (Actual – Expected)2/Expected.: For blue we have (212 – 100)2/100 125.44For orange we have (147 – 100)2/100 22.09For green we have (103 – 100)2/100 0.09For red we have (50 – 100)2/100 25For yellow we have (46 – 100)2/100 29.16For brown we have (42 – 100)2/100 33.64 We then total all of these contributions and determine that our chi-square statistic is 125.44 22.09 0.09 25 29.16 33.64 235.42. Degrees of Freedom The number of degrees of freedom for a goodness of fit test is simply one less than the number of levels of our variable. Since there were six colors, we have 6 – 1 5 degrees of freedom. Chi-square Table and P-Value The chi-square statistic of 235.42 that we calculated corresponds to a particular location on a chi-square distribution with five degrees of freedom. We now need a p-value, to determines the probability of obtaining a test statistic at least as extreme as 235.42 while assuming that the null hypothesis is true. Microsoft’s Excel can be used for this calculation. We find that our test statistic with five degrees of freedom has a p-value of 7.29 x 10-49. This is an extremely small p-value. Decision Rule We make our decision on whether to reject the null hypothesis based on the size of the p-value. Since we have a very miniscule p-value, we reject the null hypothesis. We conclude that MMs are not evenly distributed among the six different colors. A follow-up analysis could be used to determine a confidence interval for the population proportion of one particular color.

Cheating in Educational Institutes - Essay Example This report stresses that academic cheating is not a new phenomenon; it has been present since the evolution of different examination tools used in the academic arena. Davis reports that students, who believed that they would fail in a particular class or test that was being scored, resorted to cheat in order to avoid failure. This paper makes a conclusion that cheating in previous years mainly included copying someone else’s homework and presenting it as one’s own work or cheating used to take place during examination sessions while students used to carry small pieces of paper with them to copy from it during examination. Previously, cheating even constituted of asking answers from fellow students during examination sessions while ensuring that the invigilators and teachers were not aware of the event taking place. According to Staples, cheating gas becomes quite subtle and that is mainly due to information that is available over the internet. Staples state that now students tend to copy information directly from the internet and simply present them to their instructors as their own work and this form of cheating is mostly conducted by students who have just enrolled in college level of education and are not aware that this activity is even regarded as cheating under student code of conduct of almost every educational institute. Cheating is an outcome of relaxed rules as well as corrupt teaching faculty and their aim of advancing their own self interest over the interest of others. A student cannot escape after conducting the act of cheating until he/she has assistance from those who are provided with the authority of ensuring that such activities do not occur. Educational standards in developing areas are quite low, the teaching
