What Can Replace Conventional Fossil Fuel - 930 Words

What can replace conventional fossil fuel? Aviation industry has been booming over the couple of years. This would mean that the usage of fossil fuels to power the airplanes is increasing annually. Using rough calculations, it is shown that there are over 100, 000 flights flown everyday [1] . To get a clearer picture on the usage of fossil fuels used, let’s assume every usage of flight consumes 10,000 litres of jet fuel per day, so approximately 1 billion litres of fuel would be consumed. Over the course of a year, the total usage of jet fuel would be roughly 100 billion litres. However, fossil fuels are non-renewable resource that would run out one day. According to data shown below, there are only 53.3 years before we run out of fossil fuels. Therefore, alternative fuels plays a big role in turning the situation around on depending solely on fossil fuel to power an aircraft. There are various alternative fuels on market, but algae oil and liquid fuel derived from gamma-valerolactone (GVL) Source: BP Statistical Review of World Energy 2014) The main concern of finding an alternative source for jet fuel is the feasibility of the fuel for large scale usage and also the economic viability of the fuel. High cost price of the alternative fuel would only discourage companies to adapt to the new alternative fuel as it would reduce the profit of the company. The efficiency of the fuel is also a major factor that could help the persuasion of switch from conventional fossil fuel toShow MoreRelatedScience Debate : Alternative Energy1157 Words   |  5 PagesScience Debate: Alternative Energy is Better Good morning/afternoon fellow peers and staff members.

The Effects of Outsourcing in America Essay - 1299 Words

â€Å"It is the maxim of every prudent master of a family, never to attempt to make at home what it will cost him more to make than to buy† (Taylor). This quote by Adam Smith, cited by Timothy Taylor, defines outsourcing as a task that can be done within a group, but is instead done by a third-party group for less money. While outsourcing service benefits American firms, studies show it takes jobs from middle-class Americans and adversely affects the American economy; however, other research proposes that outsourcing might actually benefit the American economy. One effect of outsourcing is that it economically benefits American firms both domestically and abroad, and these benefits are the reason outsourcing is so prevalent in today’s world.†¦show more content†¦Although it may have positive effects on American firms, outsourcing does not benefit the workers who lose their jobs to outsourcing, but in fact, it hinders their ability to support themselves or their families and lead middle-class lives. Outsourcing also affects U.S. unemployment and the middle class lifestyle because it takes service-producing jobs from Americans. One study found that, â€Å"Today, the total number of manufacturing jobs in the U.S. computer industry is just 166,000, Grove notes. That’s lower than it was in 1975. Meanwhile, employment in Asia’s computer sector has swelled to 1.5 million workers† (Lamphier). This excerpt manifests that outsourcing has removed jobs from America, leaving fewer workers in certain jobs than 35 year s ago, yet it has benefited Asia whose workers are paid very low wages. Another researcher concluded, â€Å"We’ve lost 105,000 manufacturing jobs since 2000† (Trumka). This passage explains that outsourcing is rapidly decreasing the number of jobs available to Americans in certain careers and is increasing the number of jobs being outsourced. Another researcher argues, â€Å"Outsourcing places downward pressure on U.S. wages in general: American workers who are in competition with workers in low-wage countries will have a tougher time earning enough to buy a home, save for retirement, or pay for a child’s education.

Basing Theories Of Crime On The Individual free essay sample

Features Of Offenders Is Like Blaming Sick People For Their Diseases Essay, Research Paper Many theories have been developed which address the issue of whether people are born felons in footings of their physical, familial, or psychological profile, Or whether as sociologists would reason felons are made by the environment and fortunes which they encounter during their life. There have been theories put frontward to propose that a individuals physical features can find how he/she behaves. The earliest theories were in the 18th century, Lavater survey on countenance this suggests that you can state individuals character by their facial features. Some of these happening still exist in modern twenty-four hours biass / old married womans tales i.e. he s got devious eyes. Or his eyes are excessively close together Subsequently the survey of phrenology besides looked at the development of people s caputs. Gall, did an extended survey of the encephalon and how the encephalon worked. He developed the theory that the balls on the skull were where in some people certain countries of the encephalon were disproportional and this caused the balls. His survey identified 26 maps of the encephalon and those relevant to criminology were destructiveness, closeness, acquisitiveness and militance. Lombroso an Italian physician, while analyzing the skull of a felon had the idea that the nature of criminology ballad in reversion ( an evolutionary atavist. ) He felt the physical features such as tremendous jaw, high zygomatic bones, and stick outing ears supported his theory as these features were found in felons, barbarians and apes. Lombroso subsequently developed this theory further and produced a list of physical features found in felons. The list included physical characteristics such as ; dissymmetry of the face, abnormality in the eyes, ears. Nose, lips, dentitions or mentum, supernumary mammillas, fingers and toes, and inordinate arm length. Lombroso so tested his theory on a figure of convicted felons and found that 21 % had one anomalousness and 43 % had five or more this he suggested showed that felons were born felons. He did other trial with soldiers and felons and once more the felons had more anomalousnesss. Lombroso published his theories in his book The Criminal Man. He subsequently developed his theories further by including the insane felon, the epileptic felon and the occasional felon who could be influenced by environmental factors. These early theories were non decently evaluated or objectively compared to wider groups in society but these theories formed the footing for future theories in criminology. Others were critical of Lombroso and one of these was an English physician Charles Goring. He went on to make his ain research as a manner of disputing Lombroso s theories. Goring ain research found that felons were shorter and lighter than others were and he hence suggested they were of lower intelligence. There was unfavorable judgment of Goring work as in his avidity to confute Lombroso he may hold overlooked fact, which could hold proved Lombroso s theory. Again this was a wider survey and looked at more factors but it failed to be nonsubjective as it set out to confute a theory instead than measure and look for alternate accounts. Hooton so tested Goring s theory and researched a big figure of captives with a much smaller figure of non-criminals. He selected people for the research based on their physical features. He found that some characteristic were found more normally in felons than in others these were ; low brows, inclining shoulders, thin lips and tattoos. He besides went on to propose that certain physical types committed different types of offenses. Those smaller in character he said would steal while those with stockier physique would perpetrate more violent offenses. Hooton besides believed that felons with unusual physical features were besides likely to be mentally inferior. It would be of import to compare a wider non-offending group with similar features. By merely comparing one group or a limited assorted group you are more likely to corroborate your initial ideas. The impact of societies response to these physical differences would besides necessitate to be considered in footings of its impact on the felon. In 1921 Kretschmer, a Psychiatrist looked a organic structure types and mental unwellness he identified three organic structure types and suggested that different types of condemnable behavior was associated with the organic structure shapes. Sheldon developed the theory of organic structure types and linked organic structure forms to personalities. These organic structure types are still used to depict organic structure forms and personalities today. These are: 1 ) Endomorph this describes people whose organic structures are soft unit of ammunition figures that are relaxed and extravert personalities. 2 ) Mesomorphs have more athletic physiques and are more aggressive in their personality. 3 ) Ectomorph are physically thin and frail and are more introspective in their personality. Sheldon carried out research affecting two 100 delinquents and two 100 pupils who had no known record of delinquency. Through this work he found that there were more mesomorphs in the delinquent group than in the pupil group. The Gluecks did a further survey taking into history more factors including societal factors and the kid rise uping techniques and the type of subject, which the groups received as kids. From this survey the Gluecks they discovered that 60 % of the delinquents were mesomorph types where merely 31 % of the non-delinquent group were mesomorphs. However the Gluecks took their sample of delinquents from establishments and there is no history taken of institutionalisation on piquing behavior. Or how body types can impact parent s reactions/ adhering to their kids. R / gt ; Cortezs and Gatti besides conducted research into organic structure types but they used a broad choice of delinquent and non-delinquents and they besides found a higher figure of mesomorphs in the delinquent groups. Physical type theory may be accurate in placing groups of organic structure forms and the links with types of personalities but this can non account for condemnable activity entirely or all people with this organic structure type would act in the same manner so at that place must other things which affect the felons behaviour. Environmental factors can besides impact organic structure types people who are hapless may non be able to afford a balanced diet and this can impact growing. Lack of fondness can besides do kids to be little. Small kids may besides be the mark of strong-arming which can subsequently impact their assurance or do them to contend back. Taking organic structure types entirely is non an nonsubjective manner of measuring condemnable behavior but combined with other theories it may give a greater cognition about wrongdoers. Developments in recognizing chromosome abnormalcies have besides allowed other theories to develop. Persons sex is decide by whether they have X-chromosomes or Y-chromosomes Females have xx chromosomes and males have xy chromosomes. If the cell divide abnormally a individual may hold three chromosomes. Some people with xxy chromosomes were found to be intellectually subnormal. Work force with excess Y-chromosomes were besides found to be over represented in the prison population and they were thought to be more aggressive. Again this theory is limited to analyzing a group of males already in establishments and non compared to people in the community with similar chromosome abnormalcy. If an excess Y chromosome leads to more aggressive behavior does it besides affect work forces in other ways physical expressions and could people be reacting to this. Could this group of work forces be being penalised more often by the tribunals that other groups. Whether felons are born or made continues to be discussed and research into genetic sciences has helped this treatment. A survey by Lange looked art 30 work forces, 13 were indistinguishable twins and 17 were fraternal twins. All 30 work forces had been in prison when Lange looked at the work forces brothers he found 77 % of the indistinguishable brother had besides been in prison but merely 12 % of the fraternal brother had been in prison. He besides looked at a group of 200 braces of brothers ( non twins ) and found that 8 % of work forces whose brothers had been in prison another brother had besides been in prison. Lange felt this proved that piquing behavior was familial. Newman did a similar survey and found a higher per centum of similar condemnable offending in indistinguishable and fraternal twins. It is hard to turn out familial factors as twins will see the same environment during their up delivery. Even more so that other brothers where fortunes within the place could hold changed between one kid being born and the following. Society besides treats twins otherwise and expects them to be the same and have the same likes and disfavors this could besides impact how they see other people. Other surveies have looked a condemnable behavior in people who were adopted Crowe studied 52 people who had been adopted where it was known that the natural female parent had strong beliefs. He besides studied 52 other people who where the same sex, race and age at the clip of acceptance. Eight of the 52 from condemnable female parents had been arrested compared to merely two in the other group. Surveies of adoptees in other states have produced similar findings and the piquing rate is even higher if the natural parent have condemnable records and the adoptive male parent has a condemnable record. This could demo that criminalism is familial but other factors would hold to be considered. At what age was the kid adopted? What had the kid s environment and attention been like prior to the acceptance. Had they had contact with their natural parents or were they placed for acceptance at birth? Where they adopted by relations or people with no contact with their natural parents? All of these things can impact the findings. If the kid had lived with the natural parents they may hold witnessed piquing behavior. The kid may hold been placed for acceptance because the kid could hold been neglected or received hapless attention and non loved. This could so impact the kid in ulterior life. If the kid is adopted by a comparative that relation could besides be piquing or state the kid could happen out about hoe the household experience about his natural parents. Adopted kids can experience a sense of separation from their natural parent and this can impact their behavior. Adoptive parents may fear the kid will hold its parent s condemnable inclinations and someway convey this to the kid. Other influences on condemnable theory have been they development of psychotherapeutics from Freud to clinical psychologists in the 1960 s who placed a batch of importance on the affects of a kid injury and how this affected them when they were grownups. Social work and work with people who are mentally sick have besides provided other theories, which have influenced developments in criminology. Decision. The argument about whether felons are born or made will go on. The history of criminology will assist to supply the footing for farther research. Future developments in genetic sciences will give farther findings to enable this work to go on. But people are affected by the universe around them and their experience impact how they respond to other people. Although people have physical, familial or psychological features non all go on to perpetrate offenses. We still need to see what are the factors, which make some people respond otherwise. We know that poorness, rearing manner and community influences can all impact individuals behaviour, so it would be hard to impute any one theory as a cause for condemnable behavior.

Peking Opera Essays - Vocal Music, Peking Opera, Aria, Recitative

Peking Opera David Widoff Topics in Music 251 March 15, 1999 Peking opera first started to gain national recognition in the 19th century, as is probably the best-known Chinese traditional music-theater in the West. Though known to the West as Peking opera, it is referred to in China as jing ju, translated as capital theater. This musical genre contains such diverse characteristics including virtuosic singing in romantic scenes involving young lovers, stylized battle scenes at land our at seas featuring spectacular acrobatics, comical slapstick often with underlying themes of political satire, and dramatic scenes of betrayal, revenge, retribution, and triumph. The origins of the plots of Peking opera come mostly from popular legend, historical events, novels, and other narrations. Peking opera is divided into five main categories and their subcategories according to age, sex, social status and character. These include the following: Sheng (male role), Dan (female role), Jing (painted face role), Mo (a minor old-male role), and Chon (male comic role). The basic musical elements of Peking opera include arias, musical speech (recitatives), and instrumental music. Though instrumental music has many functions in Peking opera, its most important function is to accompany the singing and the physical movements and dance. The instrumental ensemble is made up of two components: the melodic (wenchang) and the percussion (wuchang). The percussion ensemble is basically made up of five instruments. The danpigu (single-headed drum), ban (paired wooden clapper), xiaoluo (small going that produces rising pitch), and naoba (small pair of cymbals). The music of the percussion ensemble is comprised of sixty conventional rhythmic patterns, all which help to indicate kinds of dramatic situations, atmospheres, or moods. Other functions that these percussion pattern perform include accompanying fighting scenes, producing sound effects, and indicating entrances and exits of dramatic personages and their social status to name just a few. The instruments of the melodic ensemble of the Peking opera are mostly comprised of strings and winds, as well as a set of ten small, suspended pitched gongs called the yunluo. The strings include the jinghu (2-stringed bamboo spiked fiddle with high, piercing pitch), the erhu, the yueqin, and a small sanxian. The winds are the dizi transverse flute, the sheng, and the big and small suona (double-reed oboes). The primary functions of the melodic ensemble are to play introductions and interludes for arias, to accompany arias, and to play incidental music for dance and miming movements. The instrumental ensemble only contains nine players in the entire ensemble. Therefore, the players are obviously very versatile, and can usually play more than one instrument. For instance, one who plays both the single-headed drum and the clapper also plays the big and small barrel drum. Vocal music in Peking opera is comprised of arias, recitatives, and heightened speech. Heightened speech is used exclusively, however, by important characters and characters of high social status, while everyday speech is used by the comics and the characters of lower social status. All Peking-opera arias derive from a group of about thirty pre-existent tune-and-rhythm patterns called ban. By setting the same melodic-rhythmic type to a different text, a new aria is produced. Defined in terms of their rhythm, tempo, and timbre, five main aria types can be identified: the narrative aria, lyrical aria, animated aria, dramatic aria, and interjected aria. In conclusion, in the Peking opera, the oral and visual elements are both equally important. The actors have both mastered highly stylized acting techniques, just as thoroughly as singing. Also, audiences of Peking operas have been shrinking rapidly. One reason is because conventions of this opera-type are deeply rooted in an old society based on Confusion moral precepts and political outlooks. Although the government has tried to remedy this by taking certain form measures, it has not caused for a significant change. Theater
