The land I love essays

The land I love essays Bruce Springsteen writes a majority of his songs about prolific times in the great American past, which most Americans have vowed to forget. He stresses the importance of the mindset we must have as Americans, throughout harsh and painful times we inevitably endure. Not many people find comfort in reminiscing about the many innocents killed in Vietnam or the souls destroyed by racial profiling in the race riots of the 1960s. In Born in the U.S.A, No Surrender, and My Hometown, Springsteen engages the listener in a patriotic mode, and makes us Americans, proud to be who we are. Vietnam was a War in America that many want to forget. It was a war plagued by unexplained deaths and fought by innocent and mentally unprepared civilians Got in a little hometown jam so they put a rifle in my hand, Sent me off to a foreign land to go kill the yellow man. Many suffered extreme losses Had a brother Khe Sahn fighting off the Viet Cong, Theyre still there hes all gone. Springsteen knew Americans needed a sense of patriotism when discussing times of negativity, such as Vietnam. Throughout Born in the U.S.A Springsteen reaches out to his listeners, because both he and us were Born in the U.S.A. Us Americans need to feel as if we are that ...cool rocking Daddy in the U.S.A. in order to change our moods and focus on other aspects of life such as rock and roll, rather than War. In Springsteens No Surrender references are made to Vietnam War, yet Springsteen forces Americans once again, to feel patriotic. Tonight I can hear the neighborhood drummer sound, I can feel my heart begin to pound. Drum rolls are necessary in funerals of those who die serving our country. He recognizes Americans feel our situation in Vietnam is worthless, and recognizes many of the soldiers are indeed tired and scared, yet Springsteen lets them remember We made a promise we swore we...

Pharmacology - Assignment Example Activated tyrosine kinase in turn activates the signalling pathways such as protein kinase C pathway, Scaffolding proteins, Ras/Raf mitogen – activated protein kinase pathway, and phosphoinositol 3’ – kinase/Akt pathway (Arora and Scholar, 2005). These activated pathways alter the DNA synthesis along with cell growth, differentiation, and others. Almost all the TKI have side effects. The common side effects of TKI are anaemia, neutropenia, oedema, thrombopenia, hypothyroidism, diarrhoea, and vomiting (Hartmann et al., 2009). At the same time, TKI molecules are now approved for clinical trials in human. TKI application for cancer treatment in dogs and cats was approved earlier, with TKI drugs such as Palladia (Toceranid), Gleevec (imatinid) and Kinavet (mastinib) (London, 2009). Before conducting the safety pharmacology tests, the regulatory guidelines for testing the undesirable pharmacodynamics effects on physiological functions should be focused. This is because, in the early phase pharmacology studies, all risk factors can be found out and eliminated. TKI are found to have adverse cardiovascular effects. So, when testing TKI in dogs and cats, telemetry has to be used for the continuous monitoring of systemic arterial pressure and chronotropic effects. The pharmacodynamic effects of TKI can be determined in the organs using tumor specimens. Surrogate marker can be used as an alternative approach. These tissues act as human models and TKI effect on these tissues reveals the potential effects of TKI molecules. (Kufe et al., 2003). These pharmacological screening methods enable the scientists to find out the adverse effects of TKI, and facilitate them to come up with ways on how the programme should be modified for human safety. The effect of the drug in or gan function, and importantly the relevance of its potential in humans

Leading Figures in American History Essay Example | Topics and Well Written Essays - 1000 words

Leading Figures in American History - Essay Example Benjamin Rush - Monticello, Sep. 23, 1800) perfectly reveal his visionary ideas. He believed in an ever changing society, in the power of every new generation to make better laws, better constitutions, he believed in a form of progress which can only become possible if the man has the freedom of thinking and expressing ideas. If he came to our century he would realize that he had given America an identity and drafted the individuality of this nation. The Declaration has been the foundation on which his descendents continue to build the dream. Benjamin Franklin was acknowledged by many writers as a "versatile genius "as he had notable achievements in many areas. He was prolific not only in writing, but also in science, as he invented The Franklin stove, bifocals, a flexible catheter and the lightning rod. As a statesman and politician he is known as the only person who signed three major documents in the American history: the Declaration of Independence, the peace treaty with Britain, and the Constitution. He would proudly read his ideas and principles in today's Constitution, the most important book in the American legislation, to the writing of which he actively participated almost 250 years ago. Frederick Douglass, another remarkable figure in the American history, once said: "What was possible for me is possible for you. Do not think because you are colored you cannot accomplish anythingSo long as you remain in ignorance, so long will you fail to command the respect of your fellow men." He was a freethinker who really believed in the power of knowledge and fought for equal rights among all people, becoming a leader in the abolitionist movement and the first black citizen who hold a high rank in the American government. The present would offer him his envisioned perspective of this nation, where the Afro-Americans have equal rights, and unlimited, in any form, possibilities in the actual emancipated society.Abraham Lincoln had a difficult task to accomplish in leading the country through the Civil War. "With malice toward none, with charity for all" (Second Inaugural Address, Mar.4, 1865), he led his fight for the abolition of slavery. He spoke the words later, but they had been living in his dream long before they were expressed. Were he able to join us today, he would see a united nation, the greatest power in the world, who adopted his beliefs and struggles to act accordingly, by giving fair opportunities to all his people. Elizabeth Cady Stanton dedicated her life to the constant fight for women's rights especially for the right to vote. Gifted with a brilliant mind she had to suffer because she was born in a time when women had no right to receive proper education and had no political power. She struggled to put an end to this unjust situation, but unfortunately she died before her dream came true. Nevertheless, it did come true, 20 years after her death, and nowadays, America has a new, moral and ethical face to show to this brave freethinker. Her fight was not in vain, the American women won their right to express themselves not only in politics but in all other existing areas. These were the promoters of the freedom of thinking, they put the basis of a country where racial, sexual and religious discriminations no longer exist. Devoted to their dream, they would see it come true if the time machine drove them to the present, because

Anthropogenic Factors Leading To Climate Change Environmental Sciences Essay

Anthropogenic Factors Leading To Climate Change Environmental Sciences Essay There is great uncertainty surrounding the science of global warming and climate change. The Earths history is full of abrupt climate changes [1]. The Intergovernmental panel on climate change at the Kyoto protocol determined in 2007 that most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations [2]. Furthermore, based on the assumption that significant anthropogenic warming has taken place over the past 50 years over each continent except Antartica, it has been concluded that anthropogenic climate change is having a significant impact on physical and bilogical systems globally [3]. Climate change is occuring on all continents and in most oceans. Changes in the natural system since 1970 have been occuring where temperature increase has taken place. These changes cannot be explained by natural climate variations alone. This implies that climate change is primarily attributable to anthropogenic factors. The Intergovernmental Panel on Climate Change (IPCC) conclude that the earth is warming and that humans are probably the cause. Technologies to decrease greenhouse gas emissions and strategies for carbon sequestraion have been found to be essential as species extinction has been found to be related to climate warming [4]. German Biologist Josef Reichholf contradicts the conclusions of the IPCC stating that there have been much faster climate changes in the past and that these did not automatically lead to a global extinction of species [5]. However the IPCC found that climate change is primarily based on anthropogenic factors but with the help of technologies, the effects could be minimized. This essay will focus on four aspects of anthropogenic factors believed to be contributing to climate change. These will explore factors such as burning of fossil fuels and deforestation. Some of the natural factors which may cause climate change will be described, such as the effects of volcanoes. Introduction: Climate change has become one of the major global issues of our times. The Earths climate is changing rapidly, due to a rise in the average temperature of the global which has a subsequent impact on a variety of geographical factors. These include rising sea levels, melting of polar ice caps, flooding of land, hotter days and colder nights, and heat waves. All these phenomena bear a threat to the Earth, its ecosystems and its inhabitants, most importantly the human race. Problems such as global food shortages, natural disasters and health risks are on the rise posing severe threat to millions of lives. The risk of floods, hurricanes and heavy rains leaves major chunks of population living in potential danger of becoming homeless at any time. Changing weathers render portions of land arid and foodless, creating food security threats. A growing population only aggravates the problem. The impact of climate change is thus extremely hazardous, and it becomes important to ide ntify the root of this problem. Climate change is a direct product of global warming. As heat from the sun reaches the Earth, some of it is absorbed by the surface and the atmosphere, and the rest is reflected back into space. However, due to global warming, more and more of this heat is being trapped into the Earths atmosphere, resulting in high temperatures. The Earths surface has warmed by more than 0.8 degree Celsius in the past century and almost by 0.6 degree Celsius in the 1970s-2000s [5]. Causes: The rise in temperature is attributable mainly to human activities which are termed anthropogenic factors. Global warming has increased over the years due to human activities of burning of fossil fuels which release harmful gases, deforestation and emission of chemicals. Other concerns are the use of gases such as Chlorofluorocarbons in refrigerators and aerosol sprays and the means of transport. Most of this damage has occurred after to the heavy industrialization over the past three centuries, from 1750 the time of industrial revolution. The impact was scientifically proven and presented by the Intergovernmental Panel for Climate Change (IPCC) in a series of reports. In 2007, the IPCC published its last assessment on the subject in which it asserted that human factors have in fact contributed widely to the resultant climate change. It is very likely that human factors are responsible for sea level rise, changing wind patterns, risk of heat waves and droughts. In fact, had it not been for the anthropogenic factors, the solar waves and volcanoes would more likely have cooled the Earth rather than warming.[6] The IPCC incorporates into its findings the concept of radiative forcing, a term which empirically measures the impact of each factor on the climate change. Radiative forcing is defined as How the energy balance of the Earth-atmosphere system is influenced when factors that affect climate are altered. The word radiative arises because these factors change the balance between incoming solar radiation and outgoing infrared radiation within the Earths atmosphere. This radiative balance controls the Earths surface temperature. The term forcing is used to indicate that Earths radiative balance is being pushed away from its normal state.[7] Thus, if a factor has a positive forcing, it means that it is contributing to an increase in overall temperature. Typically, carbon dioxide has a forcing measure of more than 1.5 watts per square meter, which is the largest forcing caused over this period. GHGs:Greenhouses gases have increased by about 70% ever since 1750, bearing direct relation with the problem of global warming.[8] These include carbon dioxide, methane, nitrous oxide. The emission of carbon dioxide gas has contributed 80% to the heating up of the Earths atmosphere.[9] Carbon dioxide is produced due to the burning of fossil fuels, such as natural gas and coal. Humans burn fuel for cooking, for deforestation, for protection from the cold. The industrialization has led to the use of fossil fuel in industries, for running of machines, and in cars. In fact, the burning of fossil fuel contributes towards 80-85% of the carbon dioxide in our atmosphere. Methane is another gas being emitted in the process which all have served to increase the greenhouse effect. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, It has increased by 145% due to human activity. These gases increase the concentration of particles in the atmosphere, which prevents heat from the sun to reflect back into the space. As a result, most of the incoming radiation becomes trapped in the atmosphere, heating up the Earths surface. Deforestation: Deforestation is another issue created by the needs of fossil fuel, agricultural land, food and space. In most developing countries, the basic need for fuel is satisfied by forest wood. Hence, forests are being burnt down by rural families on a daily basis. In addition, as agricultural land becomes less and less for the needs of growing population, people extend their space by clearing up the forests. However, the land beneath forests tends to be unproductive and devoid of natural chemicals of fertile lands. It serves as source of food for a few years, after which it becomes unfertile and useless, its nutrients get depleted, and exposure to heavy winds leave it deserted. Forest removal results in various problems such as destruction of natural ecosystems, wildlife extinction and aggravation of floods and natural hazards [10]. Forest removal not only contributes to warming due to increase in atmospheric carbon dioxide, but also, it decreases the evapotranspiration efficiency, and decrease roughness of earth surface. Both of these factors contribute to warming of the Earth. Climate change as a natural phenomenon: There is another school of thought which repudiates the claims made by IPCC regarding the climate change. According to this school, anthropogenic factors cannot be held responsible for the overall climate change, which is infect a natural phenomenon. Kininmonth in his book Climate Change: A Natural Hazard provides an alternative explanation for climate change by saying that the IPCC in its global warming model ignores the regional variation in Earths climate. Earth is a sphere, and radiation from sun is absorbed differently by different portions. The tropics absorb more incoming heat, whereas outgoing radiation is far greater than incoming radiation at the poles. Hence, the Earth is not heating up as a whole due to the effect of radiation. Moreover, circulations of the ocean current and atmosphere help distribute this energy through Earth, leaving tropics cooler as well. The excess heat in the tropics is also absorbed by the enormous ocean laye r of the tropical oceans which serve as an energy reservoir. Therefore, the resulting climate change is not caused by the anthropogenic factors, rather it is a natural variation which Earths atmosphere is prone to. Kininmonth has argued that it is a flaw in the computer models of research that has led us to blame human activities as the causal factor.[11] Similarly, it is also asserted that deforestation actually leads to both negative and postive radiative forcing. If forests are replaced by grassland, it has a cooling effect which counters the heating effect discussed earlier. Thus, deforestation may or may not be a negative concern.[12] It has also been a finding that volcanic eruptions may be a natural factor contributing to climate change. Research models developed at the Max Planck Institute of Technology showed that while volcanoes have a cooling effect on global troposphere, they may lead to a clear winter warming pattern of surface air temperature over Northern Hemisphere continents.[13] Implications and Solutions: Yet, despite the debate on the real cause of climate change, it is evident that the change is in fact occurring and the threats it poses are very real. They have strong implications, and the future may be very tumultuous for many regions of the Earth.These particularly leave developing countries vulnerable to the problems of agriculture and population growth [14]. In order to cope, it is necessary to adapt ourselves to the situation. This does not only require measures to prevent global warming, such as banning CFCs but also to become less vulnerable to its impacts by eliminating factors that aggravate the situations. Some of such measures proposed include improving agricultural management, development of efficient irrigation systems, access to sanitation and health facilities for everyone, and development of buffer systems against floods and rising sea levels. Preventive measures include development of greener technology, environment-friendly means of tra nsportation and technology for efficient utilization and redistribution of energy [15]. Conclusion: In order to mitigate and solve the problems of global warming, it is essential to identify the realistic measures that can be taken. Given the current state and rate of industrialization in our globe, it ibis very difficult to curb the production of greenhouse gases and the process of deforestation. Population growth is another factor which needs to be plugged into the overall equation of sustainable growth. In addition, and more importantly, we should identify exactly where the problem lies, and if in fact some other factor aside of anthropogenic factors is responsible for climate change. Further research needs to be carried out to understand the natural causes of climate change, as promoted by the second school of thought. References: [1] Carey, J. Shapiro, S.

The Silver-tongued Rapist in Vladimir Nabokovs Lolita Essay -- Naboko

The Silver-tongued Rapist in Lolita    You can always count on a murderer for a fancy prose style. So says Humbert Humbert at the start of Lolita in his account to the "Ladies and gentlemen of the jury" (9). He refers to himself as a murderer (he is, after all, "guilty of killing Quilty"), not as a rapist, the far more serious offense Lolita levels at him. That I, and everyone else who reads the book, call Dolores Haze by the name "Lolita" demonstrates the efficacy of Humbert's fancy prose style - under the spell of his aesthetic mastery, we, the jury, must bend to his subjective vision through memory, and thus we see the twelve-year-old nymphet as Lolita, as she is in Humbert's arms. It is difficult to castigate Humbert when we see the world through his European eyes.    Humbert's main strength is his sense of humor. Nabokov is sure to throw Humbert's way all the American kitsch he can handle - mostly in the form of Charlotte Haze. His sly insults sail over her head, but Humbert wins our approval by making sure we understand them. Similarly, we admire him be...

Crimminal Detection Essay

â€Å"Criminal investigations, in the standard case, are oriented towards cracking unsolved crime, identifying perpetrators, launching prosecutions, proving guilt at trial and bringing offenders to justice† (Paul Roberts in Tim Newburn et al, 2007: 95). How are criminal detection and/or investigation moulded and shaped by political, social and/or cultural forces? Criminal detection and proceedings never exist or function independently, the system, as a whole is an inherently complex network of interacting parties, procedures and forces. The shaping of criminal detection by both social and political forces arguably has positive and negative implications for the efficiency and effectiveness of the criminal justice system. The role and influence of information as knowledge or data shapes the investigation socially, there is a reliance on them to solve or reconstruct the crime in the most accurate way possible. The control of policy and legislation over the investigation both facilitates and constrains the pursuit of justice within the criminal justice system. The lack of research, transparency and understanding of investigative practices has resulted in a number of miscarriages of justice that evidently illustrate that politics has a substantial influence on the criminal detection and investigation process. Criminal detection and investigation is inevitably shaped by its social surroundings, as the nature of crime scene investigation has progressed and changed throughout history the external influences have also changed â€Å" criminal proceedings inevitably reflect their broader social environment â€Å" (Williams & Johnson, 2007). The reactive nature of criminal investigation calls for the collection of information in the form of data and knowledge. Knowledge is based around roles of individuals at the crime scene, potentially having beneficial and adverse effects on shaping the outcom e of the investigation. Police have the power to establish a crime scene under Parts 7 of Law Enforcement (Powers and Responsibilities Act 2002 (NSW) however can failure to recognize and do just that. The recognition of a crime scene and the first respondents actions can shape the remainder of the investigation, failure to establish a crime scene can result in the loss of evidence and loss of potential witnesses â€Å"the sooner the recording of the scene begins, the more confident the crime scene examiner (and the investigator) can be in their perspectives and opinions regarding the event (Garrison 2003:73). Furthermore the effective control of a crime scene inregards to roles, coordination and order is shaped by the relationships and understandings between relevant parties. Not understanding the chain of command, policies and procedures can be problematic as each separate party acting as sole entities can result in a an inefficient crime scene and wasted resources. The reliance on expert opinion in today’s society is reflected in criminal detection, â€Å"evidence law requires opinions about forensic interpretation to be presented by a person with specialized knowledge based on training, study or experience that substantially or wholly supports the opinion.† (Gans and Urbas, 2002) However consequently there are issues of relevance, over extended expertise and disagreements or differing opinions on evidence presented. It is normal for reports to encourage the production of reconstruction account of the actions of suspects of crime without indicating how it was made possible, it is formulated general matter based on accumulation professional experts (Williams & Johnson, 2007). Problems with exerts is further extended by the relationship they may have with other parties such as police, pressure and anxiety on forensic scientist to make findings of certainty can result in the misinterpretation or intentional or unintentional obscuring of facts. â€Å"relevant body samples were obtained, their secure transportation to a laboratory, their analysis and the detection and recording of DNA profiles can all come under scrutiny in the court process.† (Gans and Urbas, 2002) The law under Police investigation and questioning powers – Part 9 of †¨Law Enforcement (Powers and Responsibilities) Act 2002 †¨(NSW) stipulates the way information can be gained from individuals however statutory safeguards such as the ‘right to remain silent’ and human nature (unclear memory or description) can result in false or fragmented information. The corroboration or falsification of knowledge obtained through interviews with suspects, witnesses, victims and experts is done through the collection of knowledge through data. Criminalistics and trace-centred forensics is motivated by â€Å" the desire to overcome the ambiguities and interpretative flexibility inherent in human perception† Burney and Pemberton (2013). Data is obtained through the collection of samples of blood, hair, finger prints etc. Data as a means of detection is grounded in Locard’s (1910) theory that if two or more items come into contact, there will be a transfer of material between the two. Development in technology has resulted in an  increased reliance on detection through forensic science measures such as DNA profiling and fingerprint analysis, with DNA featuring in Australian cases from 1989 to the present-day. (Freckelton & Selby 2002,) Forensic evidence and DNA matching from the scene can help to confirm suspicion if there is a posit ive match or insinuate innocence if the match is negative. As in a larger societal context there is an assumption that science deluges ‘ the truth’ in a criminal detection process this can have detrimental affects and has results in cases of miscarriages of justice â€Å"In Australia there have also been several prominent miscarriages of justice, including convictions based substantially on questionable scientific evidence (Carrington et al. 1991). DNA is not always relevant to cases and does not automatically correlate to guilt for example the presence of semen does not prelude rape, as the issue is based on consent. Criminal detection and investigation is shaped by the political landscape in which it exists. The polices, regulations and expectations set by the government and criminal justice system affect the manner is which the investigation is carried out there is a â€Å" background were biometric technologies have been eagerly embraced by the government, and where claims have been made about their efficiency and authorit y† (Williams & Johnson, 2007). The law both constrains and facilities the pursuit for justice in regards to investigation. There is a need for police to find those responsible for criminal actions and protection of the public but also maintain a balance with individual liberties and human rights legislation. The manner in which policing is shaped by policy is evident in the investigative process of obtaining DNA. Police are bound by the Crimes (Forensic Procedures) Act 2000 (NSW), under which they are able to obtain DNA from individuals in various forms through both ‘intimate’ and ‘non-intimate’ procedures. Magistrates can ultimately overall individuals who do not consent to testing, resulting in intrusive procedures and breach’s of privacy all in the pursuit if justice. The political landscape further affects the investigation process through the procedures surrounding the presentation of DNA in courts. DNA evidence can and has been misinterpreted by the Jury and the Magistrate, for example R v Doheny and Adams [1997] 1 Cr App R 369. Prosecutor’s fallacy evidently depicts the issue power and influence of DNA in regards to sentencing and the need to reach a conviction â€Å"an error in relation to  probabilities that usually favors the prosecution. The forensic scientist could make the error in presenting DNA evidence by misrepresenting its probative value.† (Australian Law Reform Commission, 44.28) Polices in regard to presenting DNA need to reflect the complexity and interpretive nature of criminal forensics. Politics significantly shapes the criminal investigative process, evidently not always in a positive way. There is an understandable need to protect the community, however the issues in retrieving and presenting samples of DNA raise serious concerns of human rights issues and politics shaping criminal investigation in an undesirable way. The criminal justice system does not operate in a vacuum; it is influenced by its surroundings in both a political and social way. Evidently individuals participating in the criminal detection and investigative process are influenced by their professional relationships, roles and duties they have. The collection of data to reconstruct crimes presents issues with establishment, control and coordination of crimes scenes and how the effectiveness and efficiency is shaped by the interaction of relevant individuals. Technology’s influence and prominent position within society and everyday life unmistakably influences the criminal detection process. With a shift towards relying on new technologies such as DNA analysis and finger printing to provide the ‘truth’. Furthermore the political context in which the investigation and detection process exist plays a major role. External political pressure to prosecute affects the investigative process. Politics shapes the way in which police can carry out their job, they are both constrained and facilitated by the law. in the same context individual liberties and rights are subject to manipulation during the investigative process in the search for justice. Social and political forces influence the criminal investigation and detection process in a multifaceted and complicated way, which changes as the external environment changes.

oppertunities and challenges of the internet essays

oppertunities and challenges of the internet essays Opportunities and Challenges of the Internet In a world of light-speed data transmission, any individual with little training and expertise can make a fortune from the Internet. Many companies, like E-bay or Amazon.com, thrive from business done only through Internet transactions. As computer technology progresses, data transmission becomes faster, and as high level encryption becomes available for public use, the amount of Internet consumers also grows. Technology advances also allow employees to work from home faster and safer. A manager's first challenge is to create a presence on the web. With a phone line, computer, and HyperText Markup Language (HTML) authoring tools, a business can advertise or do business over the Internet. HTML authoring tools can be freeware, like Sausage Software's Hot Dog, or advanced and expensive utilities like Microsoft Front Page. Any computer user familiar with a word processor can effectively use these applications with minimal training. Putting the HTML and graphic files on an Internet service provider's (ISP) servers is sufficient for relatively low traffic sites. Some online businesses, like Amazon.com, handle hundreds of thousands of people, or hits, everyday. They require specialized hardware and cabling to control the vast amount of traffic on there site per day. A manager's second challenge is to make the business's web site visible on the Internet. The first step in this process would be registering a domain name. Every computer connected to the Internet has a unique number attached to it called an IP address. To simplify finding specific computers on the 'Net, the numbers where substituted with alias called domain names. The names come in two levels, before and after the "dot".

Tone (In Writing) Definition and Examples

Tone (In Writing) Definition and Examples In composition, tone is the expression of a writers attitude toward subject, audience, and self. Tone is primarily conveyed in writing through diction, point of view, syntax, and level of formality. In  Writing: A Manual for the Digital Age (2012),  Blakesley and Hoogeveen make a simple distinction between style and tone: Style refers to the overall flavor and texture created by the writers word choices and sentence structures. Tone is an attitude toward the events of the story- humorous, ironic, cynical, and so on. In practice, theres a close connection between style and tone. EtymologyFrom the Latin, string, a stretching Tone and Persona If persona is the complex personality implicit in the writing, tone is a web of feelings stretched throughout an essay, feelings from which our sense of the persona emerges. Tone has three main strands: the writers attitude toward subject, reader, and self. Each of these determinants of tone is important, and each has many variations. Writers may be angry about a subject or amused by it or discuss it dispassionately. They may treat readers as intellectual inferiors to be lectured (usually a poor tactic) or as friends with whom they are talking. Themselves they may regard very seriously or with an ironic or an amused detachment (to suggest only three of numerous possibilities). Given all these variables, the possibilities of tone are almost endless. Tone, like persona, is unavoidable. You imply it in the words you select and in how you arrange them. (Thomas S. Kane, The New Oxford Guide to Writing. Oxford University Press, 1988) Tone and Diction The main factor in tone is diction, the words that the writer chooses. For one kind of writing, an author may choose one type of vocabulary, perhaps slang, and for another, the same writer may choose an entirely different set of words. . . .Even such small matters as contractions make a difference in tone, the contracted verbs being less formal: It is strange that the professor had not assigned any papers for three weeks.Its strange that the professor hadnt assigned any papers for three weeks. (W. Ross Winterowd, The Contemporary Writer: A Practical Rhetoric, 2nd ed. Harcourt, 1981) Tone in Business Writing Tone in writing . . . can range from formal and impersonal (a scientific report) to informal and personal (an email to a friend or a how-to article for consumers). Your tone can be unprofessionally sarcastic or diplomatically agreeable. Tone, like style, is indicated in part by the words you choose. . . . The tone of your writing is especially important in occupational writing because it reflects the image you project to your readers and thus determines how they will respond to you, your work, and your company. Depending on your tone, you can appear sincere and intelligent or angry and uninformed. . . . The wrong tone in a letter or a proposal might cost you a customer. (Philip C. Kolin, Successful Writing at Work, Concise 4th ed. Cengage, 2015) Sentence Sounds Robert Frost believed sentence tones (which he called sound of sense) are already there- living in the cave of the mouth. He considered them real cave things: they were before words were (Thompson 191). To write a vital sentence, he believed, we must write with the ear on the speaking voice (Thompson 159). The ear is the only true writer and the only true reader. Eye readers miss the best part. The sentence sound often says more than the words (Thompson 113). According to Frost: Only when we are making sentences so shaped [by spoken sentence tones] are we truly writing. A sentence must convey a meaning by tone of voice and it must be the particular meaning the writer intended. The reader must have no choice in the matter. The tone of voice and its meaning must be in black and white on the page.(Thompson 204) In writing, we cant indicate body language, but we can control how sentences are heard. And it is through our arrangement of words into sentences, one after another, that we can approximate some of the intonation in speech that tells our readers not only information about the world but also how we feel about it, who we are in relationship to it, and who we think our readers are in relationship to us and the message we want to deliver. (Dona Hickey, Developing a Written Voice. Mayfield, 1993) We are not won by arguments that we can analyze but by the tone and temper, by the manner which is the man himself. (Attributed to novelist Samuel Butler)

The Changes in Healthcare Industry Research Paper

The Changes in Healthcare Industry - Research Paper Example This paper explores the changes that the healthcare industry has experienced in the last decade and also assesses possible challenges the industry is likely to face in the next ten years. It is no secret that the healthcare industry has undergone an extensive change in the previous decade. The healthcare industry has in the last ten years experienced numerous ups and downs. The life expectancy of individuals has increased amazing compared to that in 1980s. There have been numerous medical breakthroughs both in terms of health equipment and drugs. The advancement in technology has seen health care delivery services become better each year, increasing the overall efficiency of the healthcare industry. The healthcare industry has grown from less efficient to the efficient industry through technological innovations. Computers have resulted in a massive reduction in medical errors. Health records are now processed and stored in electronic form eliminating massive paperwork and minimizing possible errors altogether. Competition has also heightened in the last decade pushing health care providers to fine-tune the services they offer to clients (Ginsburg, 2005). However, the industry has not been without its downs. The cost of health care has escalated over the years. It is now more expensive to obtain quality health care than it was ten years ago. The increasing number of uninsured indicates how expensive health care has become. Healthcare has become evidently unaffordable to many people over the last decade. Nonetheless, the government has been doing its best to curb this undesirable scenario. For instance, Obama care, though faced with numerous challenges, is aimed at making health care affordable to all people. Healthcare industry is likely to experience numerous changes in the next decade. Of all the likely changes, improvement in technology stands to be the biggest change in the next ten years. The advancement in technology has been on the positive side and the healthcare industry is likely to benefit from this in the next decade.  Ã‚  

Ernest Rutherford Essay Cont Example | Topics and Well Written Essays - 750 words

Ernest Rutherford Cont - Essay Example In 1971, Earnest continued to make contributions in the field of physics through a series of experiments and would later discover that it was possible to disintegrate nuclei of light elements like nitrogen using energy from alpha particles of radioactive materials. Therefore, Earnest was the first to induce an artificial nuclear reaction, and his idea is the basis for nuclear reactions in the modern world for producing energy and weaponry. He is famous for coining the names alpha, beta, and gamma rays in a bid to classify the various forms of rays since the concept was barely understandable in those days (Nobel Media 1). In this case, the scientist made a significant contribution to electromagnetic radiation. Furthermore, Ernest observed that radioactivity of objects reduced with time (Rutherford 17). Eventually, he came up with the term half-life as the time it takes for the radioactive materials to disintegrate thus the scientist was the one who set the laws governing radioactive decay. In addition, Rutherford is the scientist behind the nuclear model of atoms where he inferred that an atom comprise a nucleus that is surrounded by many orbiting electrons and his conclusion is how modern science view atoms (Weisstein 1). Earnest‘s contribution in nuclear physics has contributed to a great deal in the area of modern physics and chemistry (Weisstein 1). The concept of radioactivity, especially the alpha, beta, and gamma rays is the basis for understanding how solar radiation reaches the earth and the overall effect on atmospheric temperature. Earnest found that gamma rays were of high frequencies and if they reached the earths surface, the temperatures could be high and unbearable for the inhabitants (Rutherford 1). In this case, Earnest made an important contribution for the modern scientists to understand how issues like global warming and
