Personal Experience with Ageism and Adultism Essay

Personal Experience with Ageism and Adultism - Essay Example The essay "Personal Experience with Ageism and Adultism" talks about the age as a factor that distinguishes individuals in the society. To begin with, when I was young, during my third-grade year, my elder brother, who was in twelfth grade at the time, and his friends once discussed an issue which all of them seemed quite unaware of. Their discussion was mainly marred by speculation and imagination of what a new education policy was about and the implication it would have on the education system. Even though I was not part of the discussion, I was sitting with them in the living room, and had an upper hand over them, having watched the broadcast about the policy and its implication on national television. They kept arguing speculatively with one of them particularly explaining a completely distorted version of the policy to the rest. At some point, I joined in the discussion, giving the true version of the policy and its implication just as I had watched on television. They took it t o another side of the argument, giving it little attention, maybe because it did not come from one of their peers, and more so, it had come from a younger person whom they did not seem to believe had the command on such matters. Even after I had told them that I had watched it on national television, they still ignored my version and continued with the argument using their own speculated versions. As the debate continued and after I had given up on convincing them, my father arrived in the house and found the debate raging on.

The Federal Sentencing Reform Act of 1984 and Social Control Essay

The Federal Sentencing Reform Act of 1984 and Social Control - Essay Example By 1970s, however, both progressivism and populism lost their appeal as stand-alone policies (Vito & Allen, 1981). While progressives had failed to provide an alternative to indeterminate sentencing, populism was seen as something that negated the spirit of the law and it was declared that "Federal judges are not responsive to the pulsations of humanity." These themes dominated SRA for some time and culminated in the development of Federal sentencing Act of 1984 with one primary aim i.e. to be fair in the purposes of imprisonment.The US Congress played a slight and indirect role in federal sentencing for about a century or so by vesting into the sentencing judge an unbarred discretion to figure out the appropriate punishment from usually a diverse ambit of potential sentences as been described by law. This rendered the judge to be in total control of sentencing and it was up to the judge only to envisage various aspects of sentencing the relevant aggravating and mitigating circumstan ces and how these all factors jointly contributed to the commissioning of the sentence. The judicial sentences were virtually subject to no review on appeal. The underlying rationale of the whole exercise was based upon "coercive rehabilitation." That invariably involved judge deciding an extensive punishment of long duration and the parole board contemplating release on the grounds of adequate rehabilitation. That whole system relied heavily on the personal discretion of the judge without much accountability. This was naturally bound to criticism as with problems caused as a result of authority wielding undeterred personal discretion and seen largely as foot loose and fancy free scenario. Congress was acutely aware by 1970s of the growing unease among the general public and pervasive problems in the judicial system that were emanating due to the lack of well defined parameters in sentence commissioning. The disparity in the sentencing system lead to a thorough evaluation by Congres s in 1984 in which it was known that the whole system was in the dire need of reform and had lost the necessary credibility required to sustain the public confidence to serve as a sufficient deterrent to crime. It was concluded in that study the inconsistency and disparity in the sentencing system was due to the inadequate sentencing application by the judiciary. Congress took initiative to redress the problem by enacting the Sentencing Reform Act of 1984. The Sentencing Reform Act of 1984 is also commonly stated as SRA; it drew a comprehensive outline for restructuring of judicial sentencing discretion that essentially changed altogether the sentencing in the federal justice system. The SRA's prime objective was to overcome the chasm of sentencing disparity. The first step that Congress took was to reject the prevalent view of rehabilitation as the foremost goal of sentencing. It redefined the objectivity of sentence as retributive, educational, and deterrent (Howell, 2004). By enacting SRA Congress sought to bring the whole judicial process above board ultimately helping it regain the trust of masses important to discourage crime, revitalizing the system by modifying its dynamics, curbing over dependence on imprisonment and upholding the dignity and discretion of judges faculty. The important points(USSC, 1991) of SRA could be summarized as follow: 1. There should be a clear and comprehensive statement of sentencing of federal law along with

Case Study Report - Essay Example Multinational companies have realised that human resource management is important as it provides global strategies that would help in managing the workforce, thus gain success and a significant market share in foreign countries (Shah et al. 2012: 28). This paper will explore globalisation and internationalisation of business firms, the structures and strategies of multinational companies and how they influence human resource management. Globalisation is a concept that has been in existence for many years. Multinational corporations emerged as a result of globalisation. In order to ensure that their businesses run smoothly, multinational corporations have developed different strategies in line with their different structures. These strategies influence human resource management to carry out different activities regarding to the recruitment, selection, training and performance of the workforce. These strategies bring some benefits and limitations to the organisation. This paper will discuss the preceding issues relating to multinational corporations and human resource management (Barber and Alegre, 2010: 11). The term globalisation has different meanings in reference to different contexts, and in this situation it refers to the quick, uninterrupted inter-border flow of technology, services, money, information, goods, ideas, and cultures all over the globe. Through globalisation firms are able to operate in many countries, utilising local and foreign labour, capital and technology, marketing, management skills and therefore, becoming Multinational corporations. Firms internationalise to look for markets, exploit firm-specific advantages and to gain access to various factors of production, labour being a key factor. Multinational corporations utilise local and foreign work forces, therefore, require an effective human resource management that will successfully manage the workforce and ensure productivity. Multinational

To determine enthalpy change Essay Chemistry Lab report 1) Experiment No: 8A 2) Objective: To determine the heat of formation of calcium carbonate. 3) Date: 26th Nov, 2010 4) Theory: The experiment consists of 2 parts: a) In the 1st part, an accurately weighed known mass of calcium is added to a given dilute hydrochloric acid. During the addition, the following occurs: Ca(s) + 2H+(aq) Ca2+(aq) + H2(g) With the help of the data of heat change of the solution mixture, the average heat evolved by one mole of calcium during the reaction can be calculated. b) In the 2nd part, an accurately weighed known mass of calcium carbonate is added to a given dilute hydrochloric acid. During the addition, the following occurs: CaCO3(s) + 2H+(aq) Ca2+(aq) + CO2(g) + H2O(l) With the help of the data of heat change of the solution mixture, the average heat evolved by one mole of calcium carbonate during the reaction can be calculated. After that, by using a suitable energy-cycle diagram, and applying Hesss law, the heat formation of formation of calcium carbonate can be calculated. 5) Procedure: Please refer to the lab. manual 6) Data: 1st Part: Reaction of calcium with dil.

Note: No temperature drop can be observed after the max temperature is attained for 4 readings. Extrapolation procedure cannot be done. Therefore, the temperature change of 1st part exp. = 28-25 = +3oC the temperature change of 2nd part exp = Enthalpy change in 2nd parts reaction Hf [H2O(l)] = -242000 J mol-1 Hf [CO2(g)]= -393500 J mol-1 source: physical chemisty I of Fillans By Hesss law: Hf[CaCO3(s)] = H1 + Hf [H2O(l)] + Hf [CO2(g)] H2 = -688. 79 kJ mol-1 8) Discussion 1. Why is the exact concentration of hydrochloric acid unimportant? The exact concentration of the hydrochloric acid was unimportant as it was present in excess, that was, to provide enough H+(aq) to react with calcium. At the same time, the exact concentration of hydrochloric acid would affect the calculation afterwards. 2. State the law which you use for calculating the heat of formation of calcium carbonate. On which thermodynamic principle does it depends? The law used was the Hesss law. It depends on the standard enthalpy change of a reaction is independent of the route by which the chemical reaction takes place, which only depends on the difference between the standard enthalpies of reactants and products, i. e. conservation of energy. 3. Why is this law useful? This principle is useful as the standard enthalpy change of some reaction might not be able to find directly, and thus Hesss law can be used and the standard the enthalpy change of the reaction can be calculated indirectly by this method. 4. Discuss the possible sources of errors. State how to minimize the possible errors. A. The solid labeled calcium is suspected to be calcium oxide, which show white color but not grey shinny color. B. Heat produced the reaction might heat up the air inside the beaker, which cannot be avoided. C. Error in reading thermometer D. Error in weighing.

Fusion :: essays research papers

Fusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei must be produced. In a gas at extremely high temperature, the average nucleus contains sufficient kinetic energy to undergo fusion. Such a medium can be produced by heating an ordinary gas of neutral atoms beyond the temperature at which electrons are knocked out of the atoms. The result is an ionized gas consisting of free negative electrons and positive nuclei. This gas constitutes a plasma.   Ã‚  Ã‚  Ã‚  Ã‚   Plasma, in physics, is an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states. When energy is continuously applied to a solid, it first melts, then it vaporizes, and finally electrons are removed from some of the neutral gas atoms and molecules to yield a mixture of positively charged ions and negatively charged electrons, while overall neutral charge density is maintained. When a significant portion of the gas has been ionized, its properties will be altered so substantially that little resemblance to solids, liquids, and gases remains. A plasma is unique in the way in which it interacts with itself with electric and magnetic fields, and with its environment. A plasma can be thought of as a collection of ions, electrons, neutral atoms and molecules, an photons in which some atoms are being ionized simultaneously with other electrons recombining with ions to form neutral particles, while photons are continuously being produced and absorbed.   Ã‚  Ã‚  Ã‚  Ã‚   Scientists have estimated that more than 99 percent of the matter in the universe exists in the plasma state. All of the observed stars, including the Sun, consist of plasma, as do interstellar and interplanetary media and the outer atmospheres of the planets. Although most terrestrial matter exists in a solid, liquid or gaseous state, plasma is found in lightning bolts and auroras, in gaseous discharge lamps (neon lights), and in the crystal structure of metallic solids.

Lives Of Saints: Christinas Strength In Resisting Societys Demands :: essays research papers

Lives of Saints: Christina's Strength In Resisting Society's Demands As you grow older it is inevitable that you will change in many ways. As a matter of fact it is impossible to survive without the ability to adapt to situations and surroundings. This ability is acquired as you age, learn and experience life. It is a part of growing up and society demands that you adapt and conform to their mores and customs. It is always difficult to veer from the path of uniformity which society leads. Many times you are able to slip by unnoticed with a minor variance from this path. However, when someone decides to blatantly blaze their own trail, often society makes their further growth and development a difficult task. As a result the community only tolerates acquiescence and conformity. Like the character Cristina in Nino Ricci's novel Lives of the Saints, it is only the most tenacious that can resist caving in to the pressure. Often, this deviance can harm others, not just the dissident. Vittorio is continually badgered for the deeds his mother performed, and he is too innocent to realize that, her independence of spirit is the reason. As well, Cristina's father does not see past the cloud which has slowly been built up in Valle del Sole. The cloud which prevents most people from seeing how the failure to be an individual rules the town, and how anyone with the nerve to be unique is ostracized. Cristina's father's failure to understand this leads to the decline and eventually their total destruction of the family structure. In many ways, the story of the character Cristina in the novel is similar to the story of Saint Christina. They both endure considerable suffering for standing up for their beliefs. In both cases they have whole villages opposing them, and neither of them give in, thus proving how strong they are. In the end, Santa Christina and Cristina end up leaving behind these villages for a better existence. The villagers continuous attention to whatever Cristina does, prevents her from living her life as she would like. Cristina's only choice is to keep to herself and go about the tedious and repetitive housework she does day in and day out. This prevents any advance in her development and growth, she is left like a skipping record playing the same thing over and over, not making any Lives Of Saints: Christinas Strength In Resisting Societys Demands :: essays research papers Lives of Saints: Christina's Strength In Resisting Society's Demands As you grow older it is inevitable that you will change in many ways.

Jazz: Urban and Rural Reactions In the 1920s Essay

Subject Area: Music and American CultureTopic: Jazz: Urban and Rural Reactions in the 1920sIn parallel with the uproar of jazz during the 1920s came the commotion of different critics from various geographical settings. Many of the white people living in rural areas disliked and rejected jazz as a musical genre. However, the urban city-dwellers were more fond of it; therefore, it was more generally accepted and frequently found in city nightclubs and radio stations. Several characteristics of cities also allowed jazz to survive in urban areas over the rural ones, such as: diversity, tolerance, a more progressive attitude, technology (media, radio), more entertainment locations, and a more educated populace. Cities were known for the more relaxed and less-religious atmosphere; in contrast with cities, the rural setting was dominated by a more religious and conservative mood with a homogenous population that was more opposed to the cultural liberalism found in the cities, jazz, and the black society in general. Unlike the rural areas of the time, the socio-cultural dynamic of urban areas, with respect to tolerance, diversity, education, nightlife, and the media, allowed jazz to thrive and become a huge part of American culture. The formation of jazz occurred between the years 1897 and 1917. When jazz bands started playing, they had no way of recording their music until 1917; and even then, the quality of these recordings were atrocious. Another aspect of early jazz was that anything that was played was ever written. Jazz evolved from the blues, ragtime, brass band music, and other musical works that were all around the United States. â€Å"One important factor that existed only in New Orleans, namely, the black Creole subculture† allowed jazz to emanate from the mentioned city (Weinstock). Another aspect of New Orleans that allowed jazz to thrive in this city was the medley of â€Å"ethnic, cultural, and musical conditions [†¦] [and] the necessary philosophical impetus for [j]azz i.e., [†¦] freedom of individual expression supported by group interaction† (Weinstock). This implies that New Orleans was one of the cities, and most likely one of the first, that hosted the new counter-culture that would soon spread throughout the United States. â€Å"The preeminence of New Orleans as a Jazz center came to an end in 1917 during World War I as a result of still another ordinance when Storyville [(an area of New Orleans that was full of dance halls and bordellos where Jazz was the  dominant music)] was closed by the Navy Department† (Weinstock). As a whole, the United States embraced jazz, but there were still many groups of people who disliked jazz and all that it represented. These close minded people, especially those in small-town America, were afraid of the fast changes that were occurring in society and that jazz was the â€Å"cause of [the] loosening [of] morals and frightening dislocations† (Roaring 1). The New York American published an article expressing the views of many conservative, white Americans who thought that â€Å"moral disaster [was] coming to hundreds of young American girls through the pathological, nerve-irritating, sex-exciting music of jazz†¦Ã¢â‚¬ (Roaring 2). White audiences in the southern part of the States were ruthless towards black people and their music. The north appeared to be more tolerant, but there were still many confrontations between blacks and whites. Jazz was a part of modernism which helped pave the way for liberals who felt pinned down by the older conservative generations. It also served as a medium for white musicians searching to liberate themselves from the conservative constraints of their time. One can see that the northern part of the states, where cities were mostly located, accepted jazz more easily and quicker. The predominance of racism and general intolerance towards the black culture was another aspect of rural areas that did not allow jazz to thrive. Since jazz was also rejected because of its African American origins, and not only because of the supposed moral decay that it provoked in the youth of America, racism also tied into the calumniation of jazz. This also affected the conservative populace of the suburbs who were afraid their young girls were mesmerized by the â€Å"black music.† Jazz was so closely tied with to African American culture that it was often referred to as being â€Å"the accompaniment of the voodoo dancer† (Roaring 2). By referring to jazz in this manner, critics were trying to degrade and undermine everything that it meant to the black community. They were also trying to lure white Americans into their train of thought and trying to get them agree with their mind mapping accusations. â€Å"Many [†¦] Americans were appalled to see their children dancing to music that was believed to have emerged from [†¦] [the] Negro brothels of the south†(Roaring 2). In addition, a plethora of jazz critics  became famous for voicing their dislike of jazz. But in fact, they hid behind their critiques of jazz in order to express, not the dislike of the music, â€Å"but the social and political dislike of the black population† (Anderson 135). The problem that worried white conservatives the most was interbreeding between black and white young people who were really into jazz mainly because it belonged to the new counter-culture. Jazz served as the highway that joined blacks and whites. Whites were not only racists towards blacks emotionally, but their prejudice expanded to influencing their physical behavior as well. Many times did the racist, anti-jazz white population try to sully jazz to something much dirtier than it truly was. Since jazz came from the black population, who were once slaves, jazz was not socially accepted as a real musical genre. It often occurred that jazz musicians were characterized as viruses that tried to infect the general population through their music. Jazz was labeled Mumbo-Jumbo (meaning non-sense) by many critics, and by this discounting jazz as any kind of music where talent is needed. It seemed like the white trend was being against jazz and it’s black producer. According to an article in the September 1918 issue of the Current Opinion: â€Å"One touch of [j]azz makes savages of us all† (Anderson 138). The goal of white critics was to undermine black music and culture. Hate towards jazz and jazz musicians in general came to such extremes as to where they were threatened through magazine articles. These articles suggested lynching, kidnappings, and murders, among others, to scare the black population. Even though that by the 1920s and early 1930s jazz had gained an international reputation and was already part of the American culture, the â€Å"racial innuendoes in articles on jazz continued† (Anderson 141). The white population continuously tried to limit jazz’s growth, by letting the jazz musicians know that their music was not welcome through critical and controversial magazine and newspaper articles. The main goal of the critics who published articles dehumanizing blacks and bashing jazz was to disenfranchise the jazz industry and to label blacks as savages who wanted to recruit more and more people to their music. â€Å"[M]usic soothes the savage beast, but we never stopped to consider that an entirely  different type of music might invoke savage instincts†(Anderson 141-42). With this, Anderson is trying to imply that blacks are savages and those who listen to jazz will turn into savages as well. By the latter part of 1924, jazz had gained many white musicians and had also grown in popularity among the white crowd. The white population came to believe that notion that â€Å"[†¦] when white people play jazz, it is jazz music, but when black people play jazz, it is jungle noise† (Anderson 144). So, in order to accept this, many critics came to the conclusion that white and black jazz were different and that white jazz was pleasing while black jazz tried to make music but only succeeded in producing noise. Critics played a huge role in dehumanizing jazz and the black population. During the late 1920s to early 1930s, Jazz became so big that it came to shape and represent the new American culture of the cities and the people of this time. â€Å"Jazz music [†¦] became a symbol for all the modern innovations that traditionalists despised[:] the new leisure, city life, Freud, and other elements of the 1920s cultural modernism†(Peretti 2). Peretti is implying that jazz became a huge part of America in a way that it helped shape the culture to what it is today. In fact, it became such a big influence, that during the 1930s white jazz musicians tried to get all the credit for jazz and succeeded in many places. Audiences would consider many white performers (i.e. Benny Goodman) symbolic to jazz. However, in big cities like Chicago, blacks were credited with the invention of jazz and their seemed to be more cooperation between black and white musicians. Chicago was one of the main destinations for black musicians who moved from rural to urban areas of the country in order to play and promote their music. It is speculated that white musicians only exploited jazz because of the commercial gain and the huge public attention that it had. It is also believed by some that they played the music in parody: in order to mock the black musicians and jazz. In many places, whites tried to take all the spotlight for inventing jazz while whites in other locations stepped out and let the black culture shine. The big cities of America were famous for their animated and wide ranging nightlife that allowed jazz to be heard by a manifold of people. Many clubs  around the states opened their doors to jazz and jazz musicians from various ethnicities, though mainly white and black. Jazz nightlife reached its peak in Harlem, New York during the 1920s. This era was also known as the Harlem Renaissance. During this time one of the most eminent clubs in that area was the Cotton Club. The elite would frequently congregate at this location which was famous for having alcohol, during the age of prohibition, and because of its jazz. Although jazz and black jazz musicians were welcomed and most of the time the protagonists on the stage, they were not allowed to be part of the regular crowd or mingle with the white throng; admission to the Cotton Club was strictly limited to whites. This was an example of how the white population discriminated the black people but embraced their music and part of their culture. American cities, like New Orleans, New York, and Chicago, were the birthplaces of jazz and allowed jazz to spread throughout the other states. Another northern city that was also affected by the ‘big bang’ of jazz music and its culture was Chicago. This was also a scene where prohibition loomed and nightclubs defied it. Big jazz bands were many times features in lavish shows put on in cabarets. Many Chicago residents turned to these destinations in search of a fun night. For many city-dwellers, joining the jazz scene was a way of protesting against prohibition. â€Å"Biting and incisive, jazz personified this protest, this direct, raw approach to life, which offended the â€Å"solid† citizen and was looked upon as sinful by puppeteers and preachers and as cheap and tawdry by small-minded classicists†(Dexter 34). Chicago was not only the scene of protest against prohibition, but also the place where many young musicians moved to with a goal to start and succeed at their own musical careers. Many prospered, but many more did not; Chicago became such a hotbed for jazz, that there were too many musicians trying to spread their sounds. One of the places where musicians could go to listen and talk to other musicians was the Three Deuces (later known as the Off-Beat Club). It was a â€Å"convenient and cheap place to meet and jam between jobs†¦Ã¢â‚¬  (Dexter 38). When jazz was on the verge of expansion, numerous small clubs appeared in many cities were jazz musicians could congregate and listen to different songs and interpretations. The invention of the â€Å"talkie†, an early form of the jukebox, had a great impact on the spread of jazz. At first, many musicians had no idea how the talkie could revolutionize the music scene. At this time, the only way to listen to music was to presence it live. The talkie allowed for a raunchy reproduction of several tunes, which became the perfect tool for the spread of the popularity of jazz. These talkies were soon spotted and nightclubs, diners, bars, and other locations, for their customers to listen to jazz (or any form of music) freely. The talkie sparked a new interest for jazz, which later led to the dispersion of many musicians from Chicago who moved on to accept jobs in other cities (especially New York). The invention of the talkie gave people from all around the country access to jazz anytime they pleased. Jazz owes all its fame, glory, and expansion to the great cities of the 1920’s America. Full of diverse people, vast places for entertainment, the radio and a more educated populace that yielded more tolerance to new ideas and forms of expression, cities opened their doors to jazz and all that this new music represented. They were responsible in allowing for the formation of jazz to what it is today; embedded in the American culture, jazz has become the only true American form of music. Though often challenged by close-mindedness, jazz managed to prosper. Jazz has not only maintained its original form through the interpretation of some talented musicians but it has also evolved to influence the popular music of today.
