Research about the Radiation Safety - Essay Example This paper aims at discussing radiation and its safety, how radiation can be measured, how it affects the lives of human beings and how these negative effects can be reduced. Radiation is majorly categorized into either non-ionizing or ionizing radiation. This classification is done in accordance to whether the radiation ionizes or does not ionize common compound matter. A radiation that ionizes ordinary chemical matter is referred to as ionizing radiation while that that does not cause ionization to chemical matter is known as non-ionizing radiation. The term radiation is under various circumstances used in referring to ionizing radiations. The most common forms of ionizing radiation are X-rays and gamma rays (Gale and Lax 123). However, radiation might also be used in referring to non-ionizing radiations such as microwaves, radio waves, heat, or visible light. During radiation, wave radiate or particles travel away from the source in every direction. This characteristic enables a t echnique of physical units and measurements applicable in both ionizing and non-ionizing radiations (Pettigrew 98). Both forms of radiation’s power trail an inverse-square law that relates to its source’s distance. This is because of the fact that both types of radiation tend to expand as they travel through space. This law only applies when the radiation is travelling in a vacuum. Radiation with the required high energy has the capability of knocking electrons off atoms thus creating ions. As much as both types of radiations can be dangerous to living organisms, ionizing radiation is by far more dangerous per unit of energy deposited. This is because even the powers from law ionizing radiations have the capability of causing DNA damage in living things. Because the cells of living things and DNA in the cell can be negatively affected by the ionization, then this type of radiation can easily lead to higher chances of getting cancer. Given that a single living cell cons ists of billions of atoms, only a small fraction of the atoms will be affected by radiation with low powers (Gale and Lax 187). Therefore, the possibility of cancer being caused by ionizing radiation on the amount of radiation that has been absorbed and the sensitivity of the tissue or organism. Particles and photons the energy of more than 10 electron volts (eV) should be referred to as ionizing. Beta particles, gamma rays, cosmic rays, X-rays, and alpha particles have enough energy that can ionize atoms. Free electrons can also be ionizing due to their ability have attraction with matter. Free electrons might occur as a result of ionization. Ionizing radiations originate from X-ray tubes, radioactive materials, particle accelerators, and some also naturally exist in the environment. Ionizing radiation is usually invisible and cannot be easily detected by any of the other four human senses. This is the reason as to why the equipment like Geiger counters are always needed to detect the presence of ionizing radiations. Ionizing radiation can be might lead to the production of some visible light when they interact with matter, as experienced during radio-luminescence and Cherenkov radiation ionizing radiation can be used in many ways in the field of medicine but can be a health hazard if not used in an appropriate way (Kudriashov 145). Exposing someone to ionizing radiation can result to the damage of his/ her living tissues. Higher doses of exposure to

Essay On Political Parties In India Essay Example for Free

Essay On Political Parties In India Essay Posted in National Issues of India by Vijay Jaiswal On August 29, 2013. No comments In a modern democratic political system of India, with governments based on Parliamentary model, political parties are central to the working of the political system. Political parties in Indian Democracy grow up the as spokesman of organized interests. Thus a Political party system in India is an organization of like minded people based together either to preserve and promote group interests or to promote a particular ideology. Usually every party seeks to promote some particular interest and ideology. The political party constantly seeks to capture governmental powers to secure its ends. In a democracy, the party gets into power through elections. In a Parliamentary system such of India, the political party winning the majority of seats in the Lower House of the Parliament forms the Government, while the Party or Parties failing to get the majority constitutes the opposition. Thus the Parliamentary government is always a Party government. It may be the government of a single party or it may be the government of a coalition of parties. The nature of political party system in India was characterized by Morris Jhones as a dominant one party system. It means that India basically has a multi-party system but one among the many parties is dominant party and monopolizes governmental power. Since independence up to the 4th general election in 1947 this was precisely the picture. The Congress party was in power during all the twenty years from 1947-67 both at the centre and in the states with a brief exception in Kerala in 1958. The 1967 elections saw the fall of the Congress monopoly in several states where unstable coalitions were established. The sixth General Election in 1977 witnessed the fall of the Congress at the centre. The Janata Government was established. But the Janata experiment soon failed. For Janata was in reality an unstable coalition. The Congress gained back its power in 1980. Then there was a B.J.P. coalition government at the centre and in few states. On the basis of their influence and aspirations, parties in India fall into two categories: All India politicalparties and regional political parties. Thus the Congress (I) or the Jananta Dal or the Bharatiya Janata Party (BJP) – are truly All India parties having some sort of influence throughout India and having All India aspirations. There are some other political parties which are professedly All India parties but their influence is limited to particular regions. They may be classed us regional parties with All India aspirations. The Communist Party of India (Marxist), the Communist Party of India, the Forward Block, the Revolutionary Socialist Party (R.S.P) etc. fall into this category. The influence of the C.P.I. (M) for example is concentrated in West Bengal, Kerala and Tripura. The regional political parties are those which are frankly regional in their aspirations emphasizing their ethnic or linguistic identities. The D.M.K. or the A.I.A.D.M.K. in Tamil Nadu, the Telugu Desham in Andhra, and the A.G.P. in Assam or the National Conference in Jammu and Kashmir fall into this category. There are also some frankly communal parties like the Shib Sena emphasizing their religious identity. On the basis of ideology, Indian parties may be classified into conservative, liberal democratic and revolutionary parties. The B.J.P. for example is a conservative party. The Janata Dal and the Congress are liberal democratic parties. The Communist Parties, the Revolutionary Socialist Party etc. are revolutionary parties seeking restructuring of the society along Marxian Lines, while the B.J.P. may be said to occupy the extreme right position in the political spectrum, the Congress, the Janata Dal stand at the centre while the Communist Parties and  the R.S.P. occupy the extreme left position.

The Token Black Guy In Teen Movies Essay -- tokenism film Hollywood

The Token Black Guy In Teen Movies â€Å"Throughout history, the powers of single black men flash here and there like falling stars, and die sometimes before the world has rightly gauged their brightness.† - W.E.B.

Atticus Finch as a Moral Character Essay

Throughout literature, there are numerous examples of characters who serve to reinforce moral values of both other characters, and the reader. These characters consistently choose to do the â€Å"right† thing in the face of severe adversity. For example, in the Parable of the Good Samaritan, the Samaritan man goes against all societal values to help the Jew after he had been left for dead by muggers. In To Kill a Mockingbird by Harper Lee, Atticus Finch serves as a shining beacon of morality in the face of the prejudice-ridden early 20th century Alabama. Atticus helps to develop healthy and moral attitudes in his children by encouraging them to avoid unnecessary conflict, to always strive to be the better person, but also to still be prepared to accept a challenge if it is necessary for doing what is morally right, which demonstrates his truly moral character. Being passive and avoiding conflict is often viewed as being weak, but in many cases, avoiding conflict can be the only responsible, morally correct choice. This is specifically demonstrated by Atticus Finch after Bob Ewell spits in his face. Atticus displays extreme restraint by refusing to fight Ewell. When asked to comment on the incident, he simply remarks, â€Å"I wish Bob Ewell wouldn’t chew tobacco† (Lee 291). In this case, Atticus demonstrates that he is perfectly willing to swallow his pride and do what is right. Secondly, Atticus further expands on this attitude by teaching his children that it is wrong to fight with neighbours, no matter what insults are said to them. After Mrs. Dubose tries to antagonize Jem, Atticus advises: â€Å"†¦hold your head up high and be a gentleman. It’s your job to not let her make you mad† (Lee 133). On this occasion, Atticus is teaching his children the old proverb of â€Å"sticks and stones† – that people should learn to ignore things that others say about them. By being peaceful and restrained towards Bob Ewell, and requiring his children to do the same to Mrs. Dubose, Atticus is teaching his children how to avoid conflict and handle situations properly, which is a critical element of acting morally. It is often difficult to travel on moral high ground, especially when there is pressure not to, but experience teaches us that it is always the best option. In To Kill a Mockingbird, Atticus provides a clear example of how to be the better person when forced into an uncomfortable situation. After Jem  destroys Mrs. Dubose’s garden, Atticus has to teach his children that people are not always going to be kind to them, especially with Atticus’ role in the Tom Robinson case, but they must still treat everybody with respect. Atticus tells Scout, â€Å"It’s not fair for you and Jem, I know that, but sometimes we have to make the best of things† (Lee 139). In this example, Atticus is teaching his children that no matter what happens, always try to be positive about it, and never to let their detractors bother them. Additionally, Atticus does not condone his children fighting. Once again, Atticus knows that there are always going to be people that are unkind to them, but that fighting will not make the situation any better. Scout mentions, â€Å"Atticus had promised me he would wear me out if he ever heard of me fighting anymore; I was far too old and big for such childish things, and the sooner I learned to hold in, the better off everybody would be† (Lee 99). In this instance, Scout remembers that Atticus does not permit her to fight with others because it is immature and damaging, regardless of what caused the fight. Therefore, Atticus’ attitude towards conflict, to be the better person, demonstrates that he understands how to behave morally when presented with conflict. Doing the right thing is often significantly tougher than indecision, or even doing the wrong thing. In To Kill a Mockingbird, Atticus Finch proves that doing the right thing might be difficult, but it is always the preferable choice, and that it is never impossible. In 1930s southern Alabama, racist or otherwise prejudiced attitudes are plentiful. This can make morally correct choices difficult. When Atticus Finch took the Tom Robinson case, he knew that the popular opinion of the residents of Maycomb would be against him. However, he understands that taking the case was the right thing to do, and that he must do it. When Atticus is explaining his decision to take the Tom Robinson case, he states, â€Å"This case, Tom Robinson’s case, is something that goes to the essence of a man’s conscience – Scout, I couldn’t go to church and worship God if I didn’t try to help that man† (Lee 139). By saying this, Atticus is acknowledging that although Maycomb may be against him, he knows he has to help Tom Robinson because it is the only way to do what is morally right. Later, Tom Robinson’s life is threatened by a mob who want to break into the jail and murder him. Atticus  is warned of this, and he goes to the jail in order to help Tom. Atticus prevents the mob from reaching Tom, telling them, â€Å"You can turn around and go home† (Lee 202). At this time, Atticus understands that he could be attacked and potentially injured, but he knows that he must make the morally correct, albeit challenging choice, and go to the jail to protect Tom. Based on this evidence, it is clear that Atticus understands that some of the choices that he has to make will be difficult, such as defending Tom Robinson in court, or protecting him from the mob. However, Atticus knows that they are the only morally right choices, and therefore the only choices he may permit himself to make, as he is a strong moral character. Acting morally does not require perfection, and any person or character will have minor flaws and imperfections. In Harper Lee’s To Kill a Mockingbird, Atticus Finch serves as a near-perfect role mode in contrast to the chaotic environment of 1930’s Alabama. His desire to avoid inane conflict, always strive to be the better person, and accept challenges in the process of doing what is right demonstrate his true sense of righteousness, and call us to act as better people in the face of adversity. If adopted by everyone, Atticus’ actions, attitudes and principles would make the world a much more pleasant place to live in.

Fake Myth

How Shadows Came To Be In the kingdom of Ridonicorn, there was a peculiar king named Shade. He claimed that he could stalk anyone without being seen. The Olympians knew him well, for his boasts were somewhat true. Often times, they bet on him to see if he tail people. Poseidon and Hermes almost always won the bets since they usually on the same side. If there was ever an argument, Artemis would settle it by choosing the right side of the bet. One day, Hermes and Poseidon didn’t place the same bet.Artemis was not there to settle the argument. This may seem trivial but it greatly upset the Olympians. They were so confused that no one else placed a bet. Poseidon thought Shade would not be able to follow the mysterious citizen and Hermes thought he would. Shade had already followed the citizen one mile into the enchanted forest near Ridonicorn when he heard a voice telling him to come into the bushes. He obeyed silently and went off his path. â€Å"What dost thou want? † sa id Shade to the voice.Then, right before his eyes, an old man with a cane came out of nowhere and said to him; â€Å"Only to help my king. † Shade was curious at his response In his weird manner of talking, he said; â€Å"What would thou doest to helpeth me in my quest from the gods? † â€Å"I have an enchanted necklace,† replied the old man. â€Å"that will make it so that no one can see hear you but the gods. † â€Å"Give it to me now! † ordered Shade. The old man gave it to him and Shade immediately put it on. â€Å"Did it work? † he asked the old man.Deceivingly, the old man replied; â€Å"Shade? Where did you go? † Shade was filled with happiness and continued his peculiar errand. He did not know that the old man was Hermes and could indeed see and hear him. Hermes was trying to â€Å"secure† his success of his bet with the necklace. However, no one knew that the person who Shade was stalking could see and hear him perfect ly. She was Artemis. She had left Olympus to take a break and hunt since she was not a good mood. When she noticed that Hermes was trying to win a bet, she was filled with nger. She shot an arrow right past Shade’s head. Shade was surprised since he thought he could not be noticed. â€Å"You think I can’t see you, mortal? † Shade shuddered. The way she said â€Å"mortal† made it seem as if she wasn’t. He was too late to notice and Artemis placed a curse on him. He and his offspring were forced to follow everyone without secrecy. Poseidon won the bet, Hermes had to do Poseidon’s chores for a millennium, and Shade (now Shadow) and his children had to follow everyone while always being seen for eternity.

Anecdote for Fathers essays

Anecdote for Fathers essays The age of Romanticism is characterized by the need for emotions and communication of feelings. The artwork of the period emphasizes sentimentality and passion, the use of imagination, and creativeness. There is sympathy towards the environment and towards the person being more nature-involved. Romantic artwork brought back the forgotten medieval epoch while augmenting elements of feeling. In music, exotic and remarkable symphonies were created under the influence of Romantic ideas. Many composers of the period were inspired by poetry that had been written. In sculpture as well, artists were able to use their imagination and work free of past carvings that may have, at one point, been thought to be competition. Romanticism placed a large emphasis on a persons individuality; man was thought to be good-natured. William Wordsworth is one of the most recognized poets of the Romantic era. He strongly asserted feeling into his writing which keeping it serene. According to Wordsworth, a poet is a reflective man who recollects his emotion in tranquility. In his Anecdote for Fathers, Wordsworth portrays the characteristics of Romanticism. He glorifies beauty and the importance of nature. The poem itself describes the point of view of a father who has been strongly influenced by his childs thoughts. The clear yet detailed description gives the reader a good idea about the setting. (In the Romantic era, a descriptive setting would have been a foremost element of the text.) The green earth echoed to the feet of lambs that bounded through the glade, From shade to sunshine, and as fleet From sunshine back to shade. This description of the setting is vivid and depicts the real image. The poem takes place with surroundings of the beautiful country. There is a conflict in the poem as to where the boy wanted to live versus where the father wanted to. Both locations, Kilve and the Liswyn farm, are illustrated to...

Biography of Francis R. (Dick) Scobee

Biography of Francis R. (Dick) Scobee Since the Space Age began, astronauts have risked their lives to further the exploration of space. Among these heroes is the late astronaut Francis Richard Dick Scobee, killed when the space shuttle Challenger exploded on January 28, 1986. born on May 19, 1939. He grew up fascinated by airplanes, so after graduating from Auburn High School (Auburn, WA) in 1957, he joined the Air Force. He also attended night school and acquired two years of college credit. This led to his selection for the Airmans Education and Commissioning Program. He received his bachelor of science degree in Aerospace Engineering from the University of Arizona in 1965. Continuing his Air Force career, Scobee received his wings in 1966 and went on to several assignments, including a combat tour in Vietnam, where he received the Distinguished Flying Cross and the Air Medal. Flying Higher He next attended the USAF Aerospace Research Pilot School at Edwards Air Force Base in California. Scobee logged more than 6,000 hours in 45 types of aircraft, including the Boeing 747, the X-24B, the transonic aircraft technology (TACT) F-111 and the C-5. Dick was quoted  as saying, When you find something you really like to do, and youre willing to risk the consequences of that, you really probably out to go do it. So, when he had the opportunity to apply for a position with NASAs astronaut corps, he jumped at it. He was selected in January 1978, and completed his training and evaluation period in August, 1979. Besides his duties as an astronaut, Mr. Scobee was an Instructor Pilot on the NASA/Boeing 747 shuttle carrier airplane. Beyond the Sky Scobee first flew into space as pilot of the space shuttle Challenger during STS-41C on April 6, 1984. Crew members included spacecraft commander Captain Robert L. Crippen, and three mission specialists, Mr. Terry J. Hart, Dr. G. D. Pinky Nelson, and Dr. J. D. A. Ox van Hoften. During this mission, the crew successfully deployed the Long Duration Exposure Facility (LDEF), retrieved the ailing Solar Maximum Satellite, repaired the orbiting Challenger on board, and replaced it in orbit using the robot arm called the Remote Manipulator System (RMS), among other tasks. Mission duration was 7 days before landing at Edwards Air Force Base, California, on April 13, 1984. That year, NASA honored him with the Space Flight medal and two Distinguished Service awards. Scobees Final Flight The next mission was as spacecraft commander of   the shuttle mission STS-51L, also aboard the space shuttle Challenger. That mission launched on January 28, 1986. The crew included the pilot, Commander M. J. Smith (USN) (pilot), three mission specialists, Dr. R. E. McNair, Lieutenant Colonel E. S. Onizuka (USAF),and Dr. J. A. Resnik, as well as two civilian payload specialists, Mr. G. B. Jarvis and Mrs. S. C. McAuliffe. One thing made this mission unique. It was scheduled to be the first flight of a new program called TISP, the Teacher In Space Program. The Challenger crew included mission specialist  Sharon Christa McAuliffe, the first teacher to fly in space. The mission itself was delayed due to bad weather and other issues.     Liftoff was initially scheduled at 3:43 p.m. EST on January 22, 1986. It slipped to the  23rd, then to January 24th, due to delays in mission 61-C, and then to January 25th because of bad weather at transoceanic abort landing (TAL) site in Dakar, Senegal.   The next launch date was January 27th, but another technical glitch delayed that one, too.   The ​space shuttle  Challenger finally lifted off at 11:38:00 a.m. EST.  Dick Scobee died along with his crew when the shuttle exploded 73 seconds into the mission, the first of two shuttle disasters. He was survived by his wife, June Scobee, and their children, Kathie Scobee Fulgham and Richard Scobee. He was later  inducted into the Astronaut Hall of Fame. Edited by Carolyn Collins Petersen.

Advantages and weaknesses portrayed by GAP with regard to contemporary Essay

Advantages and weaknesses portrayed by GAP with regard to contemporary technology - Essay Example The company to focus on in the paper is GAP which has had tremendous impact on people with regard to clothing. Research Problem What are some of the value chain advantages and weaknesses portrayed by GAP with regard to contemporary technology? Literature Review Gap is one of the oldest clothing companies in the United States of America. Since its founding in the year 1969, the company has had numerous milestones that it has overcome. This built the company’s reputation in the 1990s making it one of the top clothing sellers in the United States. Despite the fortune that it made, its market went down with the dawn of the new century due to numerous factors. However, the year 2010 saw the company begin rising again against all economic odds. It is imperative to analyze the internal situation of Gap amongst other factors in an effort to gain an in-depth understanding of the company. Analyzing the resource capabilities of the company, one major aspect to observe is the incorporatio n of intangible assets. Overlooking of these assets is a contemporary trend when understanding the structure of a company because people pay more attention to the corporeal assets within a company. However, it is important to understand that these assets play a key role in either the success or failure of a company. Technology is the intangible asset to focus on. In an effort to uphold quality inventory in its earlier years, Gap ensured that it had innovative technology that would also help the company reach a larger audience. The easy to navigate website captured the attention of many customers making it very simple for people to order clothing. As years have gone by, the company has incorporated modern age technology in an effort to increase the market value of its products. In 2009, Gap introduced a software package that would assist in monitoring its workflow and make forecasts on the effects caused by various real estate decisions made. Moreover, it acquired a system that would help intensify its e-commerce trades by faster processing of orders. With the advent of new technology, the company is bound to make even higher sales (Fleisher, 2008, 48). With relation to tangible resources, it is important to note that the company has made numerous strides in an effort to keep in touch with advancements in the industry. The company has had the ability to buy new machinery that has assisted in cutting down the costs per production. This is from the fact that in earlier years, the company had faced numerous challenges having to outsource some of its departments facing the uneven market demographics. Human resource has also worked to ensure that the company gets back to its high market position that it enjoyed in the 1990s. This is from the increased number of retail shops around the world majoring in the sale of Gap products Understanding the relative price position of Gap is also vital in comprehending the internal situation of the company. With the increase in i ts sales over the 90s decade, Gap made the mistake of lowering the quality of its products due to high demands and also increased the prices of its products. However, by the year 2003, the company had reduced its income from the loss of customers. The company thus reduced the prices of its commodities with an effort to lure back the customers but it faced numerous challenges from the market entrance of other clothing lines. The year 2010 saw the company increase the sales of its products from the moderation of prices innovation introduced by a new Chief Executive. By the month of May that year, the net sales had increased by

The Health Care Dilemma Essay Example | Topics and Well Written Essays - 1000 words

The Health Care Dilemma - Essay Example Essentially, it nationalized health care, reformed the American private health insurance sector and will work to provide universal coverage for all Americans through the â€Å"individual mandate† concept, which rules all Americans to buy insurance otherwise they will face a fine. This federal legislation is a flawed policy that needs to be repealed or amended, at the least. The fact is that it is unconstitutional, un-American and half-baked piece of legislation that has been passed in order to save President’s Obama’s face in his drive to deliver an election campaign promise. Un-American Universal coverage or the mandate for everyone to buy insurance is against American values. The United States has thrived and prospered through the freedom by which its enterprises and its citizens conducted their affairs. With the nationalized health care, the government would be encroaching on the rights of individuals to choose and decide what is best for themselves. In addition, the government is taking more responsibility for welfare than what is necessary. The country has trudged on and has actually grown in the past decades, with the government taking a laissez faire attitude and giving free rein to enterprises and nurturing capitalism. The nationalized health care law is pandering to the people through its mantra of social justice but the fact is that it is against the American ethos that defines poverty and how individuals are responsible for their own fates. Elaborate welfare systems such as the Obamacare, are inherently misguided because, instead of the social justice or a ddressing inequality, they are more prone to breed social ills simply by promoting the rejection of individual responsibility. Obamacare is against the American individualism and liberal policies that has worked for the American experience and the country to its current economic status and to sacrifice it just to satisfy some presidential rhetoric is tantamount to eroding the American economic fabric and social fabrics. Constitutional Question The Obama administration, with all its policies that advances welfare and big government is ensuring an American transition towards socialism. This development cannot proceed without sacrificing certain of civil liberties. This is already being demonstrated in the nationalized health care. The legislature has taken upon itself sweeping powers in order to curtail certain constitutional rights in order to pass the Obamacare legislation. With the law, the federal government is, in effect, forcing Americans to qualify under health coverage require ments, threatening them with punishments in the process. For many legal experts, this is unconstitutional. The state of Virginia, for instance, has already filed a lawsuit against the healthcare law, arguing that there is a legal precedence outlawing such an act. Particularly, it stated: Regulation of non-economic activity under the Commerce Clause is possible only through the Necessary and Proper Clause... The Necessary and Proper Clause confers supplemental authority only when the means adopted to accomplish an enumerated power are 'appropriate', are 'plainly adapted to that end', and are 'consistent with the letter and spirit of the constitution.' Requiring citizen-to-citizen subsidy or redistribution is contrary to the foundational assumptions of the constitutional compact (5-6). The above ruling explicitly cites how the nationalized health care is unconstitutional by virtue of its mandatory redistribution of service and wealth with the subsidy to the entire

International Conflict Analysis - Essay Example However, since the war ended in 2002, there have been several positive developments like conducting elections and involving the youth. Of course, one has to keep ones’ fingers crossed as earlier attempts at peacemaking have usually resulted in breakdown given the greed and grievance of the warlords and the presence of thousands of brainwashed soldiers ready to do their bidding. The role of the international community is also discussed and some criticism expressed for the way in which their non-intervention caused avoidable suffering and casualties. Given the interplay of the resource argument (the so-called conflict diamonds) with that of a failed state where a â€Å"free for all† was the norm rather than the exception, the peace that the citizens of Sierra Leone are experiencing now is indeed welcome from all aspects. Finally, the conflict in Sierra Leone is also notable for the way in which the post cold war illusions about durable peace and establishment of a new wor ld order were disabused. The end of the cold war produced diametric reactions from intellectuals and foreign policy experts. Whereas writers like Francis Fukuyama were quick to predict the â€Å"End of History† and proclaim that the democratization of the nations of the world would give us the meaning that we have always sought, other writers like Samuel Huntington warned of a coming â€Å"Clash of the Civilizations† where who you were mattered more than what you were or which side you were on (Huntington, 1996, 14). The former is the â€Å"new war† hypothesis that posits the view of how conflicts in the last two decades are about economic reasons and identity whereas the latter is the â€Å"old war† theory about the cold war which was essentially an ideological battle. However, there are many who see the so-called new wars as a continuance of those fought earlier just that the international order does not have the

Key Areas Essay Example | Topics and Well Written Essays - 250 words

Key Areas - Essay Example Town hall meetings are an effective strategy because they offer opportunities for the nurses to discuss a policy issue with a policy maker in the presence of community members (Stewart et al., 2009). These structured discussions offer the nurses and the policy maker to listen to the community and identify some of the concerns and ways of dealing with the issue. In addition, the nurses can inquire for follow up questions to clarify some of the responses (Mason et al., 2011). Additionally, when people are going for a town hall meeting, they are aware of the issue at hand and try to get more information to ask the host (Mason et al., 2011). In this regards, it acts as a way of helping people get more information within the society to learn about its effects, prevalence and ways on how to control it. However, town halls are not an effective strategy because the people may become â€Å"numb† to town halls especially if there have been numerous others that have not addressed their concerns (Stewart et al., 2009). Therefore, in order to make town halls effective, it would be imperative to address the concerns aired and adopt some of the solutions offered. Stewart, P. A., Salter, F. K., & Mehu, M. (2009).

Astronomy 1 - Research Paper Example The space between the universal objects is not vacant and contains gases that are distributed in the space. Due to this phenomenon, absorption lines are created into the universe that are called intercellular lines of gases. Due to expansion of the universe, the stars and other stellar objects are moving farther and faster as compared to speed of light. Therefore, Hubble law is used to find the distance in the universe (Goldsmith & Owen, 2001). Stars are just like light emitting bodies. Decrease in brightness can be observed if one moves them further away. Simple mathematical rule is applied for notifying change in obvious brightness of stars as a function of its distance from us. . The mathematical formula is as follow. Luminosity of star is also used to write inverse square law. Luminosity is energy that star emits in each seconds which is measured in watts. It can be described in following manner. If luminosity of star is known then brightness can be measured. Then brightness is used for calculating distance (Goldsmith & Owen, 2001). Geologists have assumed that rocks in earth structure are some 4 billion years old. The stones came from moon and mars also seem to be having same history. It is assumed that earth and planets formed at the same time when sun was formed. Thus our sun is about 5 billion years old approximately. It is huge ball of gas mostly containing hydrogen which is contained due to gravity (Goldsmith & Owen, 2001). The new energy source of sun was proposed by a British astronomer at the end of world war one. He puts three ideas together. Astronomers knew that presence of hot and dense gases at center of sun are helpful in supporting its weight. Expanding high pressure hot gases maintain the outer layer of sun.

The Report – Part II Introduction Wrest Park is located ? miles east of Silsoe which is halfway between Luton and Bedfordshire on A6. Wrest Park is considered to be the birth place of the traditional English garden and currently is a beautiful showcase developed over three centuries, consisting of French, Dutch, Italian and English garden landscapes, added on over the years. It is an inspirational journey through art in landscaping. There is plenty to see and do here at the park, including shopping, visiting the cafe for lunch, checking in at the visitor’s centre for all the places to visit on t he grounds, including travel cart rental sign-up. Visitors can visit the Wrest Park mansion to see the home where the de Grey family has lived for over 600 years and also visit the formal gardens just behind the mansion (Wrest Park Online 2012). Building the Communication Strategy The goal of any communication strategy is to inform the target market about the product or the service, and in this case, it is the Wrest Park as a historically artistic landscape. The goal is to provide a communication which brings in more customers who will pay fees to enter and walk or ride through the park, shop and eat lunch at the grounds cafe. The money brought in will help sustain the operations in maintaining the park to its fullest grandeur as a historical archive in landscape art. The more people who know about the park and visit it, the more they will share their experiences with others who will, in turn, come to visit too. The park has many benefits and features for visitors and it is importan t to emphasize those (Boone 1999). The communication strategy is developed first with determining the target audience through research, which also includes members on the database, then deciding on the objectives of the communication message. The next part is designing the message through content, structure and format. Following that process comes the important part of deciding how to send out the message to the right target audience to maximize the return on investment (ROI). The last part is deciding where the message comes from. The communication must be accurate, timely and relevant (Jain 1997: Zikmund

Consumer Behaviour Essay Example | Topics and Well Written Essays - 1750 words

Consumer Behaviour - Essay Example While the youth and children are the primary decision makers on certain categories of products, among the adults the decision rests with the one who contributes the maximum towards household expenses. Based on these factors Starbucks is advised to cater to the discerning consumers products and service that would make them feel distinguished. Table of Contents 1. Introduction 1 2. Motivation & Benefit 2.1 Theory of Planned Behavior 1 2.2 Self-identity 1 2.3 Uniqueness Theory 2 2.4 Scarcity and attractiveness 3 2.5 Organic coffee and its impact 3 2.5 Customer preferences 4 2.6 Physical environment 4 2.7 Recommendations for Starbucks 5 3. Family Life Cycle and Family Decision-Making 5 3.1 Family Life Cycle 5 3.2 Stages in FLC and choices 7 3.3 Family decision-making 8 References 10 1. Introduction Starbucks is an upscale, recognized coffee brand enjoying competitive advantage. They have 17,000 stores in 49 countries and their greatest strength is their strong brand image and a considera ble market share. The UK coffee market, according to a study by Mintel in 2010, is expected to grow and is forecast to be worth GBP976 Million by 2015 (PR Newswire, 2010). On an average adults consume about two cups of coffee per day and Starbucks has less than 1% of the global market share (Kotha & Glassman 2003). Competition being intense, Starbucks needs to understand the motivation and benefits that consumers seek. 2. Motivation & Benefit 2.1 Theory of Planned Behavior Consumer behavior is associated with idealized people and communicates information about consumers (Smith, Terry, Manstead, Louis, Kotterman & Wolfs, 2008). It communicates their personal values and their self-identity. The Theory of Planned Behavior (TPB) suggests that behavioral decisions are not spontaneous but the result of a reasoned process in which behavior is influenced, even if indirectly, by attitudes, norms and perceptions of control over the behavior (Smith et al. 2008). The attitudes, norms and the pe rception of control over behavior influence behavior through their impact on behavioral intention. Food choices including the intention of consuming environmentally friendly products are all influenced by the TPB. 2.2 Self-identity People buy a product for the value they can deliver. The purpose, the product and the person interact to shape consumer behavior and any changes on any of these could impact consumer behavior (Ratneshwar, Shocker, Cotte and Srivastava (1999). How the product or service contributes to their self-identity and well being influences consumer behavior. The teenagers, for instance, like to be seen at trendy places. To them the social experience and the perceived brand value hold importance (Lockyer 2009). Self-identity is the extent to which the individual sees him- or herself as a typical consumer of a product, and may play a role in the context of the consumer (Smith et al. 2008). Self-identity, an important determinant of behavior, reflects the label people use to describe themselves. To boost their self identity consumers can consume food and also consume food at places that would help distinguish them. Self-identity predicts intentions to consume fair trade products and unique products. 2.3 Uniqueness Theory Food can either be consumed publicly or privately. Consumers like to experience goods and services that will distinguish them from others. Hence advertising should be unique in its appeal to the coffee consumers.

Native Americans and European Colonists Essay Example for Free

Native Americans and European Colonists Essay At the start of the seventeenth century, Native Americans greeted European settlers with much excitement. They regarded settlers as strange, but were interested to learn about the new tools and weapons Europeans brought with them. The native people were more than accommodating to the settlers, but as time passed, Europeans took advantage of their generosity. â€Å"Once these newcomers disembarked and began to feel their way across the continent, they forever altered the course and pace of native development. † Native Americans and Europeans faced many conflicts due to their vast differences in language, religion and culture. European settlers’ inability to understand and respect Native Americans lead to many struggles that would eventually erupt into violent warfare. Many natives thought the armed Europeans would be able to protect them from their more powerful native enemies. In many cases, Europeans did help natives in warfare. Samuel de Champlain, a critical figure in the establishment of the New France colony, aided the Montganais, Algonkaian and Hurons in their fight against the Iroquois. Champlain and his tribes used European firearms to frighten and defeat their enemies. â€Å"The Iroquois were much astonished that two men should have been killed so quickly, although they were provided with shields made of cotton thread woven together and wood, which were proof against their arrows. † In decades to come, Europeans were not be so friendly toward Native Americans, using firearms to take native lands and resources. Native Americans relied on â€Å"gift exchange† system that allowed different tribes to specialize in the production of a certain goods. They would trade their goods with other native tribes. Native Americans hoped to incorporate Europeans into this system. For a while, natives did trade skins and hides, receiving wampum, sacred blue and white shell beads, in exchange from the settlers. â€Å"Exchange is meant not only the trading of material goods but also exchanges across community lines of marriage partners, resources, labor, ideas, techniques and religious practices. † Natives generously shared their belongings, supplies, food, and the skills necessary for survival in the New World with the settlers. In exchange, settlers gave Natives disease, death and robbed them of their lands. Within ten years of the first arrival of European settlers, the Natives welcome had worn out. The settlers had appeared on the scene with two objectives in mind in regards to the Native Americans: obtain their land and convert them to Christianity. Europeans judged natives for their different language, their lack of clothing, and the absence of government and religion in their society. The Europeans established their own set of laws on native soil and held natives accountable to these laws. Any breach of European law by Natives residing in the area resulted in public humiliation, a practice unfamiliar to Native society. More complications accumulated due to their vast differences in language, religion and culture, but it was the differing views of land, that caused violent conflict. With more and more Europeans arriving in America, they needed more land to settle and grow crops. Also, at this time, the demand of tobacco was greatly increasing. The tobacco industry amounted for most of the settlers’ exports. To grow tobacco, settlers needed large plots of land. In the Native American’s eyes, the land was to be shared with the European. Natives had no understanding of the selling of land to European settlers. Europeans used this to their advantage, acquiring large plots of land without fully explaining the terms of the negotiation to the natives, or properly paying them. At first, natives sold land to Europeans, believing that this agreement would still allow them to use the land. Later, they realized that Europeans were rapidly establishing private uses on these lands. Colonists strongly objected to native settlements on the lands that they hoped to establish businesses on. Many more problems arose since the arrival of Europeans in America. Europeans introduced a variety of deadly diseases to North America that Native Americans had never been exposed to before. The colonists and explorers brought measles, smallpox, cholera, and yellow fever, which drastically devastating the Native American population. â€Å"The collected wisdom of generations could vanish in a matter of days if sickness struck older members of the community who kept sacred traditions and taught special skills. † Not only did the natives fear for their own lives, they feared for the future generations of native people. They feared that their traditions and culture would be forever lost. The relationship between Native Americans and Europeans began as a way for Europeans to learn about the lands they wished to inhabit. Natives can be given credit for teaching the first settlers how to survive in the new land. Due to the greed and arrogance of the European settlers, relations with natives turned sour. This struggle of co-existence would continue into the nineteenth century, resulting in the devastating mistreatment of Native Americans. [ 1 ]. James H.

Colonial Democracy? Essay -- essays research papers

Did democracy exist in the colonies during the eighteenth century before the American Revolution? Democracy is rule by the people, simply put. This on a large scale is nearly impossible. How could all the people of America, then or now, or even of a decent size town today all come together to vote on issues. We today have a representative Democracy, which in itself is a logistical compromise on a true democracy. In analyzing the government they had in the colonies and comparing it to the â€Å"Democracy† that we have today there are enough similarities that I would have to call the form of colonial government Democratic.   Ã‚  Ã‚  Ã‚  Ã‚  In the colonies, not everyone was allowed to vote this was certainly not democratic, but the criteria to be able to vote weren’t very extensive. The only real requirement was the owning of land. This today we might see as a hard thing to obtain. In those days land was very cheap. To make it even easier to obtain, laborers were paid well. This gave immigrants the ability to earn enough money to buy land in a short time, and farm it on their own. This also is the reason labor was in high demand, so many of the labors bought their own land and moved off to it. Labor was in short supply for this reason, and thus laborers were paid well. More than ninety percent of the people were farmers, most of who owned their own land. All these people would be able to vote.   Ã‚  Ã‚  Ã‚  Ã‚   If you were to compare the percentage of thos...

Do not go gentle into that good night by Dylan Thomas :: Poetry

"Do not go gentle into that good night" by Dylan Thomas is a poem about death. Dylan Thomas wrote this poem during the last illness of his father's life. The author creates an image of death with the use of the sons pleading words asking his father to fight against the darkness that is taking over and leading him into the afterlife. Dylan Thomas meticulously creates an image of death through the use of cunning words and by giving each word a deeper significance than its literal connotation. The author uses the image of death in every paragraph of the poem. It is one of despair and gloom. Dylan Thomas uses the words "night (1.1)" and "dark (2.1)" to describe the certain outcome of the father. Thomas declares "Rage, rage against the dying of the light (1.3)" to generate the feeling that death is unpleasant therefore forming a grim image for the reader. The author also uses numerous literal undertones throughout the poem to produce a melancholy attitude in the reader. He speaks of "wise men (2.1)", "good men (3.1)", "wild men (4.1)" and "grave men (5.1)" all coming to their death without any hope of life continuing thus encouraging the guarantee that everyone will come to their end. The literary element of tone is also present in this poem. Thomas sets the tone by conveying his anger about death by using grim words coming together to create a poem only nineteen lines long. Thomas also repeats "Rage, rage against the dying of the light (1.3)" and "Do not go gentle into that good night (1.1)" several times, communicating a dreadful tone to the reader. By using these strategically placed words and phrases, he forms a word-repeating pattern that is often found in the tone of anger.

Citizenship Birthright Under Fire

Citizenship Birthright Under Fire Summary During one morning in Washington, DC, Senator Mitch McConnell who is the Senate minority leader, argued with Senator Lindsey Graham of South Carolina about the 14th Amendment to the Constitution. The 14th Amendment grants citizenship to anymore born in the United States. Graham spoke out saying the Amendment was a mistake because children of illegal immigrants could become citizens if they were born in the United States automatically.He also stated as well as granting legal status to millions of illegal immigrants, he would also amend the 14th Amendment in order to nullify future unauthorized immigration. Republican and Democratic lawmakers were surprised with Graham’s proposal since he was basically the only Republican to negotiate with Democrats to create an immigration overhaul bill. This debate has been centered on the citizenship clause â€Å"All persons born or naturalized in the United States, and subject to the jurisdiction th ereof, are citizens of the United States and of the state wherein they reside. People against this amendment have argued that illegal immigrants are not under U. S. jurisdiction and therefore America-born children should not be automatically become citizens. The amendment has been practiced since the 1860’s and if the law were changed it would make babies born from Mexican mothers illegally they would become immigrants at birth. Opponents against the amendment say that Mexican mothers would have the babies here in the U. S. so that hopefully the mothers would receive citizenship. The only thing is by law American citizen children must wait until they are 21 years old to apply for legal residency for their parents.About 4 million citizen children have at least one parent who is an illegal immigrant. Even though Graham is pushing to reconstruct the amendment it would be huge political proposition. Opinion I woke up this morning, proud to be an American. I do not usually think w ould if I was born somewhere else or would if my relatives never came over to America? Or even would if the 14th Amendment was never thought of or brought up? I just go about my day as usual. If I really look into it and think about it, if my relatives never came to America, I would not be sitting here in this comfortable chair, typing this paper for my government class.As a matter of fact I, as a human being, would not be here. My grandfather’s roots are from Mexico and my grandmother’s are from Germany. If it was not for the 14th Amendment, they would have not met or have been able to be in this country. People come to America for a better life and opportunity. The U. S. is very diverse with different cultures, religions, and races and yet some people whose ancestors came over here are arguing that it is not fair for other people to have an opportunity to succeed. Yet I sort of see why they are complaining because America gets bigger every year due to people coming o ver

Free Time

There are lots of pleasure grounds all over the world. I think everywhere there are pubs, discoes, clubs, etc. We go out with my friends especially to pubs where we can chat, listen to music, dance and eat something. But the garden parties are more friendlier and cheaper. We usually organize barbecues with children, this time they can play and run in the garden. I usually go to a wellness-weekend with my husband once a year in winter because we work a lot all of the year.There are some well-known spas in Hungary, for example, Hà ©và ­z and Hajdà ºszoboszlà ³, and many people, including foreigners, go there. A hobby is an activity that you like doing and do quite often. Hobbies are a form of recreation. If you have a hobby, it’s easier to regain energy after a hard day’s work. Depending on the type of the hobby, you can also make friends. Unfortunately many Hungarians spend their free time at home watching TV. But there are some who do some physical activities regula rly, like swimming, aerobics or hiking.Nowadays many young people spend much of their time playing computer games either at home or in internet cafes. I think men and women usually have different kinds of hobbies, for example, very few women go fishing and they are not so interested in extreme sports, either. On the other hand, men generally aren’t interested in needlework or pottery. In my opinion both men and women do gardening but they tend to do different jobs in the garden.Women like dealing with flowers, they weed the flowerbeds, plant new varieties and they design the whole garden. Men usually prune the trees, trim the hedges and mow the lawn. Collecting stamps, coins, autographs, phone cards, beer mats or napkins, model building, doing needlework or woodwork, pottery, basketry, playing an instrument and dancing are indoor hobbies, while hiking, mountaineering, caving, sailing, fishing, canoeing and bird-watching are outdoor hobbies. My sister’s hobbies are coll ecting phone cards and diary writing.I like reading about feng-shui and I like to be an Avon consultant. I used to play handball for years, nowadays I only watch handball games on TV. As far as I know, the English like playing golf and cricket, and there are quite a few soccer fans among them. They often mow the lawn and wash their cars at weekends, while some British people go to horse races to bet or just to watch the race. Some Americans go to baseball and basketball games regularly to support their teams.But there are others who prefer staying at home and watching these games on TV while eating snacks. I think Hungarian people collect the same things that people like collecting all over the world, mostly stamps and coins. If we considered a sport that many people pursue popular, the most popular sport in Hungary are football, handball, hiking and aerobics. If a popular sport means a sport that many people watch, besides football and handball, the most popular sports are Formula 1 racing, water polo and boxing.

Mission and Vision Statement Essay

A mission statement is a formal short written statement of the purpose of the company or organization. The mission statement should guide the actions of the organization, spell out its over all goal, provide a sense of direction, and guide decision making. It provides the framework or context within which the company’s strategies are formulated. A mission statement talks about the present leading towards the future. Your mission statement may change, but it should still tie back to your core values, customer needs and vision. A vision statement takes into account the current status of the organization and serves to point the direction of where the organization wishes to go. As means of setting a central goal that the organization will aspire to reach, the vision statement helps to provide a focus for the mission of the corporation, business or non profit entity.

In the United States the Group's associated undertaking operates as Verizon Wireless. During the last two financial years, the Group has also entered into arrangements with network operators in countries where the Group does not hold an equity stake. Under the terms of these Partner Network Agreements, the Group and its partner networks co-operate in the development and marketing of global services under dual brand logos. At 30 September 2007, based on the registered customers of mobile telecommunications ventures in which it had ownership interests at that date, the Group had 241 million customers, excluding paging customers, calculated on a proportionate basis in accordance with the Company's percentage interest in these ventures. Vodafone seeks to be the worldwide communications leader in over the period of the next 2-5 years. In order to accomplish this, they will first and foremost have to deal with telecommunication industry regulations (Damien & Kerf 2003). Vodafone also consistently has to address customer complaints that stem from their competitors. International trends also play a factor, including "the liberalization of the terminal equipment market and the market for value-added services" (Bauer 1994). In order to stay ahead of the g... ing against global sourcing decisions across companie, and provid[ing] compliance measurement reports," as well as perfect the use of cellular phones for "tracking persons through the global positioning system" (Bauer 1994). According to Balsinde et al.: Multiple opportunities are open for Vodafone. One, cheaper UK-US phone calls would divert traffic from Europe to be routed via London to the US, turning Britain into a vital telecommunications hub. Two, There is still a huge market which is still untapped for mobile services. About 78 out of a hundred UK residents still do not have mobile phone services; this is a potential market that Vodafone needs to address. Three, Vodafone can create a strong market niche in the 3G telephone systems set-up since it has the technological advantage, financial expertise and marketing network to compete with other major players. The fourth strength is the full liberalization of the telecommunications market will enable Vodafone to make its presence felt in the new member countries of the European Union (EU). The fifth strength is that once the benefits of EU industry regulation outweigh their potential costs, Vodafone can operate unhampered in the EU. The efficient allocation of regulatory resources will result in consistent regulatory decisions across EU member-states. The sixth strength is that the UK economy offers low business taxes, low real interest rates, robust growth in demand, substantial falls in equipment prices and the effect of a strong stock market in reducing the cost of capital. These positive factors favor business growth in areas which require the installation of substantial new capital such as the mobile phone business. The seventh strength is that the overall picture of telecommunications in the UK is one

Journal of Korean Melodrama Christmas in August (1998) Movie Review

Journal of Korean Melodrama Christmas in August (1998) - Movie Review Example Jung decides and tries his best not to get into a relationship with her but eventually they form one. The film tends to have a weak plot but there is a strong in-depth look at both the characters that the audience can implicitly feel. The audience see and feel how Jung experiences the illness and how he deals with the people during the last days of his life. There is a silence among the members of his family because they are the only ones aware of it. Jung also holds back his emotions when he is with his friends and that is a painful moment. The relationship with Da-rim and Jung is the central focus of this story. Da-rim affects him deeply and how he responds to her is a beautiful feeling in the film. People often take others for granted but Jung’s character gives an emotional sensation to the audience on how painful it is when you know you don’t have time. In addition, the interesting thing about this film is that there are not many dialogues throughout the film. This is a strong point but it may as well start seeming to be a negative point as it drags the movie in some scenes. But this technique works for the emotional audience as the awkward and meaningful silences bring out the feel between the characters even in scenes when Jung is working alone and there is silence which expresses his isolation, pain, and loneliness. There is another major element in this film which is the subtleness. The audience get a sense that Jung and Da-rim have fallen in love but the film doesn’t really show a formal acceptance or declaration of their love. Jung would never talk about his illness but it is evident how it is affecting his relationship. The film does not even disclose the actual illness that Jung is going through and thus the movie is subtly explained through the actions and expressions of the characters that have done a great job on screen. This fact may leave the film open to several interpretations; it would also make this film thought

The relationship between price and Money Supply Research Paper

The relationship between price and Money Supply - Research Paper Example This is done by issuing sufficient monetary instruments when required. The Central banks also help the government in designing the currency of the country, which includes all the unique features. 2. It is involved in regulating and co-coordinating with the government and the stated economic policies of the country. 3. The interest rates are also controlled by the central banks to maintain price stability within the country. It also has to keep a track of the inflation in the market. The Central Banks of all the countries have an effective plan for managing the public debts. They do this through the sales and purchase of government papers such as bonds and securities. 4. The Central Bank is also known as a banker's bank. This means that the commercial banks of the countries are also regulated by the Central banks of the respective country. The Central bank not only regulates them but also provide adequate financial assistance in time of need. 5. The central bank needs to ensure the pr oper functioning of the financial systems within the county. They regulate the banking system within the country and are answerable to the world market (Downes & Vaez-Radeh, 1991). Balance Sheet Analysis The Balance Sheet of Central Banks has the list of all the liabilities and the assets that the Central Bank possesses. It is important to study the balance sheet of the Central banks in order to understand how they implement the monetary policy because the balance sheet reflects the sales, purchase records of the Central Bank and also states the holding. The Central Bank is the in charge for issuing the country's currency and it also posses the power to eliminate the power of the currency. In short, we can say that the balance sheet shows the true picture of the actions of the Central Bank. The balance sheet of a Central Bank focuses on three main components: bankers to commercial banks, Issuing the nations' currency and banker to the government of the country (Jadhav, 2006, p. 246) . The Balance Sheet needs to be analyzed from two viewpoints such as: as an issuer of currency and duty to maintain the price stability and the growth of the economy through attaining the monetary policies of the countries' economy. It is important to know certain important perspectives to understand the balance sheets of the Central banks. Firstly, the central banks are fully government owned. There are very few exceptions, but in that case there are certain restrictions on the share-holding patterns. Secondly, Central banks are the only banker for the government of ever nation. Finally, the Central bank also has to take care of the public debt. It has to always see that the net foreign asset is higher compared to the currency, so as to see that the domestic demand of foreign currency is duly met The monetary base The two components of money supply are monetary base and money multiplier. Monetary base includes the reserves and the outstanding currency of the economy. It comes in th e asset side, in the balance sheet, of the central bank. It links the central banks to the other measures of the money supply. So we can

Human resources Essay Example | Topics and Well Written Essays - 500 words - 3

Human resources - Essay Example Current competitive environment has made employees more devoted towards their work and they end up having issues with their personal life (Friedman 2008). Various relationships have experienced breakups due to increased devotion towards work by either one or both members of the couples. Due to problems in personal life, organizations end up paying higher costs (Beard 2011). Researchers have proven that increase in work-life imbalance has resulted in high employee turnover rate, increase in number of days when employees are absent from work, health issues, dissatisfaction from job and life, and increased pressure on managers (Imam 8644). All of these problems are directly linked with decrease in productivity of an organization. When the rate of employee turnover increases, work is halted until empty positions are filled (Beard 2011). When employees do not attend work, the amount of production that they would have been able to conduct is compromised. Dissatisfaction from working condit ions results in de-motivating the workers to work efficiently and effectively, which decreases the quality and the quantity of goods produced. The organizations do not only face loss of productivity due to work life imbalance, they even end up paying higher cost incurred for employee’s psychological health, which is disturbed by this imbalance. Various ways have been continuously pointed out to solve the problem of work-life imbalance; managers need to assess these ways and create programs constituting these methods to increase productivity and increase work-life balance. Managers can offer flexible work timings to employees, for example, managers have to allot a specific number of hours for an employee to work and the employee can decide what bracket of hours he choose to work (Kanter 2010). Managers can assign a work day of 5 hours to an employee and the employee can choose whether to work from 9am to 2pm or 2pm to 7pm etc.

Asthma. Pathologic basis of disease Research Paper

Asthma. Pathologic basis of disease - Research Paper Example Asthma can be divided into different groups on the basis of severity of attacks that are mild intermittent, mild, moderate and severe persistent asthma. But typically the asthma is classified into extrincsic asthma and intrinsic asthma. Extrinsic asthma is set off by type 1 hypersensitivity reaction caused by an extrinsic antigen. Intrinsic asthma is initiated by various mechanisms including pulmonary infections caused by viruses especially, cold, stress, exercise and inhaled irritants. Some categories classify asthma in accordance to the agent that causes the constriction of air passages for example seasonal asthma, exercise asthma, occupational asthma, drug induced asthma and asthmatus bronchitis. The genetic susceptibility to type 1 hypersensitivity, chronic inflammation and bronchial hypersensitivity are the major factors that cause asthma. Our immune system contains Type 2 helper T cells (Th2) which is type of CD4+ helper T cell secretes interleukins. The interleukins then promote allergic inflammations and stimulate B cells to produce IgE and different antibodies. Type 1 helper T cells (Th1) are also a type of CD4+ helper T cell which secretes interferon-ÃŽ ³ (gamma) and intereukin-2. The interferon-ÃŽ ³ (gamma) and interleukin-2 activates the macrophages and cytotoxic T cells which kills the viruses and other invading organisms. These two types of helper T cells form an immunoregulatory loop that is the cytokines from type 1 helper T cells inhibit type 2 helper T cells and cytokines from type 2 helper T cells inhibit type 1 helper T cells. These two types of helper T cells respond to different immunogenic stimuli and try to destroy them. Any imbalance in the regulatory loop of these two types of helper T cells makes it easier for the viruses and agents to attack the bronchopulmonary tree and cause inflammation which leads to asthma. In patient suffering from hypersensitivity as occur in asthma, when an antigen is presented to the skin, a wheal and flare reaction occurs. This wheal and flare reaction is clear example of hypersensitivity type 1. In air passages when the allergen reaches the epithelial lining it stimulates the induction of type 2 helper T cells (Th2). The type 2 helper T cells secrete various cytokines such as interleukin 4 (IL-4) and interleukin 5 (IL-5). The interleukin 4 (IL-4) then triggers the production of immunoglobulin IgE by the B cells and promotes the growth of mast cells. The interleukin 5 promotes the growth and activation of eosinophills. The reaction mediated by IgE to the allergens elicit an acute response and late phase reaction. The acute response to the allergens consist of bronchoconstriction, edema, mucous secret ion and in rare cases the decrease of blood pressure. The acute response occurs by this mechanism; the contact of antigens to the mast cells stimulates the secretion of mediators which mediate the reaction. In the case of air passage diseases when the allergens reach the mucosal surface, the reaction of allergens first occurs with the mucosal mast cells. In this reaction mediators are secreted which opens the tight junction in between the mucosal cells and improve the entrance of the antigens to the submucosal mast cells. This reaction causes the broncoconstriction, edema and mucous secretion which is acute response. Vagal stimulation in lungs also called bronchoconstrictio

They’re all wasted! Essay Example for Free

They’re all wasted! Essay â€Å"They’re all wasted! † proclaims The Who’s Roger Daltrey in 1971’s â€Å"Baba O’Riley,† a song widely and mistakenly believed to be titled â€Å"Teenage Wasteland† because of the refrain. Putting an emphasis on â€Å"all,† this is a sweeping indictment: the youth are all wasted, not just one group or in one way, but everywhere and in every faculty. Every potentialfor rebellion, discipline, pleasure, beliefhas been squandered. But The Who were far from the first to imagine this modern wasteland. T. S. Eliot’s poem, â€Å"The Wasteland,† provides a wide-ranging critique of modernity, while also modeling the aesthetics of the new epoch, that makes statements like The Who’s intelligible while building on established literary and social conventions. The historical context for Eliot’s poem can be divided into three major components. First, there is the literary tradition writ large, the collected textual productions of the world over the last several millennia. â€Å"The Wasteland† makes reference to the Bible (20-3), Buddhism (173), Dante (62-5), Shakespeare (172), Greek tragedy (218), and many more sources: the Norton Anthology’s cup runneth over with footnotes. Second, there is English literature. It is more likely that Eliot’s peers would measure him against the immediate backdrop of national history, not least because education in excellence in English literature is also education of the excellence of English literature. Thus Eliot must be able to demonstrate knowledge of Shakespeare and Marvell at the minimum, but also make an original contribution to the English literary tradition coming out of the nineteenth century. As in â€Å"The Love Song of J. Alfred Prufrock† Eliot addresses nineteenth century British Romanticism with modern inversions of the celebration of unadulterated nature. In the opening paragraph we have a modernized parallel of Wordsworth’s â€Å"A Beauteous Evening, Calm and Free†: Summer surprised us, coming over the Starnbergersee With a shower of rain; we stopped in the colonnade, And went on in sunlight, into the Hofgarten, And drank coffee, and talked for an hour. (8-11) The natural world is pleasing and comforting to humanity in this miniature. The surprise of rain does not seem to dampen the spirits of the characters but rather, through the stop in the colonnade, causes them to pause and so appreciate the reappearance of the sunlight. The construction â€Å"Summer surprised us† gives the natural world and its seasons a kind of playful agency, as in the Romantic tradition. However, we cannot think of Eliot as remaining within the Romantic tradition despite his utilization of it as a literary option. The third vital context is the recently concluded World War I. Hence the agency of the natural world, insomuch as Eliot images such agency for literary purposes, is as ambivalent as human nature. The opening lines, also drawing on literary precedent in Chaucer’s â€Å"Canterbury Tales,† depict a less loving nature. April is the cruellest month, breeding Lilacs out of the dead land, mixing Memory and desire, stirring Dull roots with spring rain. (1-4) The April showers that bring May flowers, to paraphrase Chaucer, bring a conflation of life and death instead of pilgrims. April is personified, as in Romanticism, but here it is so that it can be labelled cruel. Life is not an abstractly generative force: since at least Sidney’s â€Å"Astrophel and Stella† and Shakespeare’s â€Å"Sonnets,† English literature has had a rich tradition of sexual metaphorics, using phrases like â€Å"Dull roots† for phallic impotence and â€Å"spring rain† for ejaculatory procreation. But Eliot cannot simply celebrate this cycle of rebirth in the shadow of the muddy graves of World War I. The â€Å"mixing / memory and desire† recasts the common literary relationship between sex and death in a perverse light, since â€Å"memory† transgresses the partition between the living and the dead, the present and the past. Memory exhumes what is past, does not allow it to die and rest in peace. This corpse is now also the object of â€Å"desire. † The cycle of death and rebirth has been stalled in modernity and in the vision of â€Å"The Waste Land. † Eliot’s poem both represents and partakes of this modern problem; in fact, the necessity of participating in the forces of social infertility to represent it might be one of the most distinctively modern aspects that Eliot represents here. The broad scope of historical literature that he can draw on is the result of the British empire contacting and importing cultural products from around the globe. His knowledge of languages and availability of translations when necessary further speak to world literature as a thoroughly modern phenomenon. The need to reject or critique prior traditions is also part of the modern awareness of the dialectical nature of history. Of course, this also marks (ironically) a point of continuity with Victorians like Baudelaire (67). The fragmented form of â€Å"The Waste Land† is part of this modern rejection of tradition, but to depict this fragmentation Eliot must also gather together multiple traditions. They are juxtaposed with each other but without a master narrative to organize them. To further drive the point home Eliot also uses non-standard grammar or spelling, or seemingly nonsense words and sounds: â€Å"O O O O O that Shakespeherian Rag† (128). This ambiguity then contrasts with the grim and undecorated conversation circling, like Hemingway’s â€Å"Hills Like White Elephants,† around an abortion: â€Å"I can’t help it, she said, pulling a long face, / It’s them pills I took, to bring it off, she said† (158-60). Stylistic innovation and rejection of stifling â€Å"rules† of art allow Eliot to create a radically new expression of the human experience, but in doing so he simultaneously duplicates the rootlessness and anomie he is seeking to overcome. â€Å"The Waste Land† articulates combatting notions of history, progress, and form that do not reach any conclusive resolution in the poem or in its subsequent readings. With the aid of hindsight the critic can understand Eliot’s growing religious conservatism in subsequent works like â€Å"Journey of the Magi. † By trying to include every literary and theological mode, he winds up putting them all at a discount; even if one’s chosen credo is somewhat arbitrary it at least allows entrance into the myth of rebirth. The forces in tension in â€Å"The Waste Land† chart two continuing political alignments. The will or willingness to subscribe to any belief is most darkly visible in the rise of the Third Reich; the willingness to subscribe to none is most visible in our inability to decisively commit to the prevention of subsequent atrocities. Eliot’s poem provides a space for considering these questions without prejudicing the question through contemporary political affiliations. The political question can be momentarily set aside if we imagine, for the time being, that this is merely art for art’s sake. Works Cited Eliot, T.

Efficiency Rise in PCDTBT:PC70BM Organic Solar Cell

Efficiency Rise in PCDTBT:PC70BM Organic Solar Cell Efficiency Rise in PCDTBT:PC70BM Organic Solar Cell Using Interface Additive Rashmi Swami, Rajesh Awasthi, Sanjay Tiwari Abstract Solar cell can be designed with photoactive layer of organic and inorganic materials. Organic materials, particularly polymers, are a promising alternative to traditional semiconductors as the active material for solar cell because of their low cost, low temperature energy processing, low material requirement, can be used on flexible substrate, can be shaped to suit architectural application. Low efficiency is one of the biggest problem with organic solar cell. In order to increase the efficiency of bulk hetero-junction organic solar cell we are using interface surfactant additive poly(oxyethylene tridecyl ether) (PTE) with blend photoactive layer. Here we are reporting on the enhanced photovoltaic (PV) effects by means of a polymer bulk-hetero-junction (BHJ) layer having PCDTBT which is poly(N-9-heptadecanyl-2,7-carbazole-alt-5,5-(4,7-di-2-thienyl-2,1,3†²-benzothiadiazole)) as a low-band gap e’ donor/HTL polymer and PC70BM which is [6,6]-phenyl C70 butyric acid methyl e ster as an acceptor/ETL, doped with poly(oxyethylene tridecyl ether) (PTE) which is an interface surfactant additive. For PCDTBT:PC70BM organic solar cell , we recorded 0.886 V open-circuit voltage (VOC), 11.7 mA/cm2 short-circuit current density (JSC), and 47.3% fill factor (FF) and PCE of 4.9%. For PCDTBT:PCBM70:PTE organic solar cell, we recorded VOC of 0.904 V, higher values of JSC of 13.8 mA/cm2, FF of 48.2% and improved PCE of 6.0% for a PTE concentration of ca. 0.164 wt%. Power conversion efficiency (PCE) reaches to 6.0%, by the addition of PTE to a PCDTBT:PC70BM system which is much higher than a reference device not including the additive (4.9%). Increase in efficiency is because of the increase in lifetime of charge carrier, which is due to the existence of PTE molecules at the interfaces sandwiched between the BHJ photovoltaic active layer and the anode and cathode, in addition to the phase-separated BHJ domains interfaces. Keywords – Organic Solar Cell, PCDTBT, PCBM, PTE, IPCE, Bulk hetero-junction. Introduction The global rising demand for low-priced electricity has triggered deep research on solar cells comprising organic semiconductors. Organic solar cell (OSC) technology has received significant attention over the past decade due to the simple, flexible nature of polymer photovoltaics and the potential to develop a clean, cost-efficient renewable energy source. The key development of organic solar cells has been made with the pioneering concept of ‘‘bulk hetero-junction (BHJ)’’ photoactive layers [1-2].The bulk hetero-junction (BHJ) PSC [1][3] is of particular interest, due to the efficient photo-induced generation of charge in its blended photovoltaic (PV) layer, that is consisted of interpenetrating, channel-like domains of separated fullerene and polymer. Following the annealing of the BHJ structure at elevated temperatures, PSCs with PV layers of P3HT which is poly(3-hexylthiophene) and PCBM60 which is phenyl C61-butyric acid methyl ester have shown high pow er conversion efficiencies (PCEs) of 3-5%. Efficiency of P3HT:PCBM organic solar cell is upto 5% because of the limitations of conventional P3HT, whose bandgap lies at around 1.9 eV, which limits absorbance to wavelengths below 650 nm [4]. To improve the efficiency of PSC we need new active materials having lower bandgap to harvest more solar photons. More recently, a PCE of 5-6% was reported for a BHJ PSC that used a blend of PCBM70 and PCDTBT having a bandgap of 1.88 eV [5,6]. Using ‘processing additives’ PCE of organic solar cell can be increased [7-9]. To increase carrier lifetimes (reduce recombination loss) we modify the BHJ interfaces between the phase-separated domains of the donor-conjugated polymer and the acceptor fullerene, and added a non-ionic surfactant poly(oxyethylene tridecyl ether) (PTE) as an additive to the PV layer. In this paper we investigated J-V characteristic and IPCE spectra of PCDTBT:PC70BM organic solar cell with and without PTE. 1.1 Donor molecule Next generation HTL/donor material for organic photovoltaics is Poly[[9-(1-octylnonyl)-9H-carbazole-2.7-diyl]-2.5-thiophenediyl-2.1.3 benzothiadiazole-4.7-diyl-2.5-thiophenediyl] (PCDTBT) shown in Fig. (1) which can produce better efficiencies and lifetimes. The main qualities of PCDTBT are lower HOMO and LUMO levels narrow band gap Increased open circuit voltage Longer wavelength absorption Lower concentration and material usage Improved stability under ambient conditions High electron and hole generation rate and high mobility of electron and hole. Fig. 1. Molecular structure of PCDTBT. 1.2 Acceptor molecule Extremely symmetrical cage-shaped molecules of carbon atoms is Fullerenes as shown in Fig. (2). For the separation of photoexcited exciton into free charge carriers blending of conjugated polymers (electron donor) with fullerenes (electron acceptors), is extremely efficient way. Fig. 2. Molecular structure of PC70BM. 1.3 PTE additive Poly(oxyethylene tridecyl ether) (PTE) shown in Fig. (3) as an additive have low (- 8.1 eV) highest- occupied-molecular-orbital (HOMO) and high (à ¯Ã¢â€š ¬Ã‚ ­2.1 eV) lowest-unoccupied-molecular- orbital (LUMO) [10–12]. Fig. 3. Molecular structure of PTE. Experimental Details The sample BHJ PSCs were fabricated in a sandwich structure with an anode of indium tin oxide (ITO) and an Al:Li/Al cathode. Patterned 80-nm-thick ITO glass was cleaned by sequential ultrasonic treatment in detergent, deionized water, acetone, and isopropanol, and then treated in an ultraviolet-ozone chamber for 15 min. Then, a ca. 40-nm-thick hole-collecting PEDOT:PSS buffer layer was spin-coated onto the ITO electrode. On the top of the PEDOT:PSS layer spin coat the blended solution of PCDTBT (0.456 wt%), PCBM70 (1.824 wt%), and PTE additive in dichlorobenzene. The PV layer was about 85 nm thick. Finally, for the cathode, a ca. 1-nmthick Al:Li alloy (Li: 0.1 wt%) layer and a pure Al (ca. 50-nm-thick) layer were created on the photovoliaic layer through thermal deposition (0.5 nm/s), at a foundation pressure below 2Ãâ€"10-4 Pa. The sample device structure studied was therefore [ITO/PEDOT:PSS/PCDTBT:PC70BM:PTE/Al:Li/Al] as shown in Fig. (4). The active area of the fabricated device was 3Ãâ€"3 mm2. For comparison, a reference PSC was fabricated with the structure [ITO/PEDOT:PSS/PCDTBT:PC70BM/Al:Li/Al] as shown in Fig. (5). In 100 mW/cm2 illumination intensity produced by an AM 1.5G light resource, the performance of the PSCs was measured,. With the help of a source meter (Keithley 2400) the photocurrent-versus-voltage (J-V) characteristics were measured. The IPCE (incident photon-to-current collection efficiency) spectrum were measured for the PSCs studied using an IPCE measurement system. Fig. 4. ITO/PEDOT:PSS/ PCDTBT:PC70BM:PTE /Al:Li/Al Organic Solar Cell. Fig. 5. ITO/PEDOT:PSS/ PCDTBT:PC70BM /Al:Li/Al Organic Solar Cell. Results And Discussion As shown in Fig. (6) for PCDTBT:PC70BM organic solar cell , under an illumination of AM 1.5G and 100 mW/cm2, we recorded 0.886 V open-circuit voltage (VOC), 11.7 mA/cm2 short-circuit current density (JSC) and 47.3% of fill factor (FF) and PCE of 4.9% a value comparable with those reported by others [6]. For PCDTBT:PC70BM:PTE organic solar cell, we recorded VOC of 0.904 V, higher values of JSC of 13.8 mA/cm2, FF of 48.2% and improved PCE of 6.0% for a PTE concentration of ca. 0.164 wt%. These increased values resulted in an improved efficiency of 6.0%, which led to a PCE that was up to 22% higher than that of PCDTBT:PC70BM based organic solar cell. Fig. 6. The current-voltage characteristics of BHJ OSCs with and without the PTE additive. We further investigated the PV performance of the OSCs that incorporated the PTE additive by studying the IPCE spectra. Fig. (7) shows the observed IPCE spectrum of the PSC devices. It can be seen that the IPCE values are consistent with the variations in JSC for the OSCs with and without the PTE additive. The maximum IPCE was 73.0% at 470 nm for the sample device with the PTE additive, which corresponded to the highest JSC (13.8 mA/cm2 ), while the IPCE value was about 60.9% for the reference device without the additive, which had the lowest JSC (11.7 mA/cm2 ). Fig. 7. IPCE spectra of PCDTBT:PC70 BM OSCs with and without the PTE additive. Conclusions In conclusion, we have reported on the use of a low-bandgap PCDTBT:PC70BM-based PV layer that incorporates a PTE surfactant, which was used to the BHJ interfaces in OSCs. We have shown that BHJ OSCs that contain the interface PTE additive are more efficient than conventional OSCs. A high PCE (6.0%) was obtained for our PCDTBT:PC70BM (1:4 w/w) OSC device using 0.164 wt% of the PTE additive, which yielded improvements in PCE of up to 22%. This improvement may be attributed to the increased selective flow of dissociated charge carriers, not only at the interfaces of the PV layer and the electrodes, but also at the BHJ interfaces between the PCDTBT and PC70BM domains. Our findings show that a combination of PTE interface additives and high-performance low-band gap PV materials holds great potential for the development of a new generation of highly efficient OSCs.
