Recommend the ideal country in Latin America where Intel should open Assignment

Recommend the ideal country in Latin America where Intel should open its manufacturing plant, based on the evidence in the case study - Assignment Example However, as only one country needs to be chosen, Intel should consider the benefits and risks associated with manufacturing and operating in either of these countries. It should be noted that Intel's main concern in opening a microprocessor manufacturing plant in Latin America is to strengthen its position in the global market. The rationale of choosing a Latin American country is to distribute risk as it already has a number of production plants in Asia. Also, the preference of a Latin American country is its proximity in the US where the microprocessors will be shipped. Most importantly, Intel is also aware of the more intense rivalry between players in the global market which significantly drives down the price of microprocessors. The company is very concerned with finding a possible way of reducing the cost of production in order to offer the final products at a more competitive rate. Aside from these considerations which were directly mentioned by Intel, the case also developed the idea that the company prefers a country where its expatriate employees who will be in operation and supervision of the manufacturing plant during the start-up stage will be comfortable in the selected site. Also, Intel also explicitly stated its preference for a deal which is done in a transparent and legal way. Intel strongly opposes "special deals" or "special incentives" as it will post problems for the company in the future. 4.0 Alternatives As stated above, four countries which include Brazil, Chile, Costa Rica and Mexcico were short listed as the preferred locations. The appendix summarized the result of the research and on-site visit of the site selection team. In terms of workforce availability, all the countries under consideration satisfy Intel's requirements except Costa Rica which still needs further training. It should be noted however, that labor cost in Chile is relatively higher. Costa Rica is the best choice in terms of labor unions and regulations as all the other countries mentioned are significantly unionized. Infrastructure and transportation are excellent and impressive in Chile, Brazil, and Mexico. Though Costa Rica's land transportation is fine, regular flights which are imperative in Intel's operations are lacking. Electricity is cheapest in Mexico at $0.02. As Costa Rica is very much eager to capture huge foreign investments, the government provides various exemptions in terms of tax holidays and discounts. All the other countries are hesitant in giving investment incentives. Expatriates are seen to be better off in Costa Rica and Mexico. Operating in Brazil will require huge taxes while the distance from US and Chile is a concern. 5.0 Recommendation Based on the discussion above, this report recommends that Intel locate its microprocessor manufacturing plant in Costa Rica. This decision is based on the fact that the country has a stable political environment, low level of corruption, attractive investment incentives, and a government which is willing to comply with Intel's requireme

The culture high Movie Review Example | Topics and Well Written Essays - 750 words

The culture high - Movie Review Example Although the position supported in a film is arguable, its creators did a good work to make â€Å"The Culture High† informative and engaging to watch. The plot of the film is centered on the discussion of the current status of marijuana in the United States with its creators openly arguing for marijuana legalization. A significant part the film is dedicated to explaining the side of proponents of legalization, who state that marijuana is not more dangerous or harmful than alcohol, but its prohibition allows underground business and cartels to prosper and conduct more violence. As it is argued, â€Å"marijuana does not cause lung cancer while more than 5 millions annually die from tobacco worldwide.† (The Culture High) Further, it is exposed that criminalization of marijuana can be linked to the government and other private organizations making profit from it by massively incarcerating the population. However, at this time, other sectors of the economy are in need of funds. Since President Richard Nixon declared the â€Å"War on Drugs†, millions were imprisoned on minor marijuana charges. (The Culture High) As a resul t, rose the need for private prisons, which according to Howard Bloom, â€Å"make it profitable to incarcerate people† (The Culture High) Subsequently, it is suggested that marijuana prohibition is needless, but is still maintained not for the sake of keeping order in the society and protecting a common citizen, but for continuing militarization of the police forces and gaining profit while denying Americans their rights, manipulating and misleading them. Although â€Å"The Culture High† mostly operates with popular arguments, it is quite informative for a person who is not an adept at the issue being raised. From one side, the film contains much information that has been actively and often discussed in the media, leaving little space for a kind of a discovery to be made.

Haber-Bosch Process Alternatives

Haber-Bosch Process Alternatives â€Å"Should resources be invested in searching for an alternative to the Haber-Bosch process†. Introduction: Ammonia’s ongoing consumption in the world is startling. The production of ammonia (NH3) was the turn of the 20th century, a startling breakthrough in organic chemistry for the world to stand in astonishment. Two scientist; Fritz Haber and Carl Bosch, made this breakthrough through the chemical procedure called the: ‘Haber-Bosch Process,’ (N2+ 3 H2→ 2 NH3.) However they weren’t the first to try the synthesis of ammonia from its elements (www.nobelprize.org, 1920.) prior to the discovery of synthetic ammonia and long before the commercial application of it, early farmers knew that certain properties of carbon based by-products which led to: human waste being scattered in Chinese farmlands, grinding of skeletons in Europe and the exploitation of Peru’s readily-available guano, due to its natural nitrogenous compounds, and the discovery of Nitrogen Fixation Processes (www.firt.org, 2012.) The need for Ammonia was directly related to the worldâ₠¬â„¢s survival, the fixed nitrogen from the air is an incredible and needed ingredient for fertilizing. Many principles of chemical and high—pressure processes were discovered and expended for the optimisation of the known nitrogen fixation process. Industries in the 19th and 20th century saw the ongoing need for nitrogen and turned to their already in use factories for producing coal to use the by-product of coking, ammonia sulphate. This along with the previously mentioned methods was how ammonia was produced pre-Haber-Bosch Process. From these early discoveries evidence can be seen as to why the Haber Bosch process is the best way of producing ammonia for the growing world. Two more scientists by the name of Priestly and Cavendish used electrical sparks in the air to produce nitrates, done by dissolving the oxides of nitrogen to form alkalis. Nitrogen Fixation, fixating Nitration as calcium cynamide proved evasive for commercial use, but later proved useful for the produc tion of chemicals requiring the cynamide configuration. There were numerous other process ect. Thermal Processing, cyanide formation, aluminium nitride formation and the slow process of decomposing to ammonia were deemed to elusive for sustainability due to the scarce amount of chemical components for the organic production to be made, resulting in to high of cost. With Habers-Bosch large-scale catalytic synthesis of ammonia from elemental hydrogen and nitrogen gas which had reactants that were inexpensive (Hydrogen, Nitrogen and Iron as a catalyst.) Using high pressure (~5000c) alongside high pressure (~150-200 atm), the process involved forcing almost completely unreactive gaseous nitrogen and hydrogen to have the product of Ammonia. This high-energy process has undergone extensive modifications in the 21st century which goes on to prove that resources should not be devoted in the search for an alternative to the currently used Haber-Bosch process because the structure of the proc ess is the most balanced of the mentioned processes of making ammonia even in the 21st century with a need of 150 million metric tonnes of ammonia (Chemical and Engineering News, 1996); 80% of which is used in agriculture where 48% of the resulting produce is responsible for the world’s ongoing consumption, however there are a few methods that give an idea for very good alternatives that could replace Haber-Bosch, but would not be as efficient. Discussion on Methods: What has made the Haber Bosch process so great is its low cost and readily available materials as seen in this method, this however has been as previously mentioned modified many times since Haber’s work: Ammonia synthesis from nitrogen and hydrogen, a reversible reaction is as follows: (1) And the equilibrium constant is (2) (www.ias.ac.in, 2012) From our understanding of organic chemistry we can see that production of ammonia is a exothermic reaction with a exponential amount of heat released. As previously mentioned the reaction is reversible, the forward reaction being ammonia synthesis, and the reverse reaction being ammonia decomposition. The decrease of the volume derives from the decrease in the number of moles of gas from the equations, two and one. With the use of Le Chatelier’s Principle (See appendix one), from this it can be seen that by increasing the pressure in the reaction causes the equilibrium to shift to the right resulting in a higher yield of ammonia produce since there is a pressure drop accompanying the transformation; the decrease in the temperature then also causes the equilibrium position to move to the right again resulting in a higher yield of ammonia since the reaction is exothermic as previously mentioned. Figures 1A and B show the effect of temperature and pressure on the equilibrium mole fraction of ammonia. It can be seen that the ammonia mole fraction decreases as the temperature increased just as the pressure increases. Figure one. (A is the mole fraction of ammonia in the state of equilibrium at varying temperatures to result in a given value of pressure. B is difference pressures at fixed values of temperature in Kelvin, data supplied by www.ChemWiki.org Temperature (K) Pressure (Atm) The conclusion then that ammonia synthesis according to the first equation is an equilibrium reaction that is favoured by low temperature and high pressure which. The reaction does not proceed at ambient temperature because nitrogen requires a lot of activation energy for the dissociation to happen (www.Topsoe.com). In the gas phase of the reaction, the dissociation occurs only at around 3000 °C (ChemWiki.com). Looking at the hydrogen molecule in the reaction, which has a weaker molecular bond, only dissociates markedly happened at temperatures above ~1000 °C (ChemWiki.com, 2012). Which shows that the reaction cannot be performed at lower temperature because it needs high activation energy to happen, if there was an increase in the temperature with a enough level, the reverse reaction predominates (www. http://abacus.bates.edu/, 2010). This is where scientist decided to have the role of the iron catalyst come in. Figure two below shows the energy profiles for ammonia synthesis in the absence and presence of the catalyst. The hydrogen and nitrogen molecules lose their translational ability to be bound to the catalyst surface. This reduces the activation energy dramatically and makes the forward reaction go faster, which makes sense to us because catalyst can’t do nothing else but speed the reaction up. Other minor components of the catalyst includecalciumandaluminium oxides, which are there to support the absorbent iron catalyst and help it maintain its surface area over time, andpotassium, which increases theelectrondensity of the catalyst and so improves its activity (ChemWiki.com, 2012). This means that scientist can rid the need for extremely high temperature conditions, a problem Haber encounted while trying to find commercial success. Something for us to know it the use of lower temperature reaction conditions means there is limited reverse reaction which is energy saving as well, this reinforces the idea of the Haber-Bosch Process being the bes t there is. For industrial use however, there is still a need for reasonably high temperatures (250–400 °C) to dissociate the N2 and H2. (Figure two, the effect of catalyst on the activation energy). Supplied by www.Chemguide.uk. Now that we know the advantages of the current Haber – Bosch Process, we can look into how carbon-free ammonia comes into the world. Licht wrote a paper on the two current chemical reactions that are now used most widely in ammonia synthesis: CH4+ 2H2O→4H2+ CO2 N2+ 3H2→2NH3 These won’t be explained because they already have previously. 3CH4+ 6H2O +4 N2→ 3CO2+8NH3 Licht wrote of a proposal for the use of ammonia as a fuel for automobiles. Although Licht did not specify the products of the ammonia oxidation, it looked into the possibility that this fuel cell might prove reversible in the case where a product was nitrogen gas, which looks into the fixation of Nitrogen, an electrochemical path to ammonia. However scientist need to overcome the extreme stability of the nitrogen-nitrogen bond in N2gas, nitrogen fixation always requires the need of gas with a metal (www.theenergycollective.com, 2012), which in biological systems the metal in question is molybdenum (as well as the used iron as the catalyst), making molybdenum, along with iodine, the only elements in the periodic table that are essential to this project.Haber he speculated that there was a better catalyst, uranium which we will look at later. A metal catalyst is required in the electrochemical process as stated, in this process the catalyst is iron, but in this case it is necessary that the iron, present as an oxide in the process, be in the form of nanoparticles suspended in molten alkali hydroxides, where future research can be done on the use of other molten oxides, notably, cesium hydroxide, which may prove superior however the variables in the process with respect to temperature, operating voltage, current and the physical nature electrodes will also need to be detailed in research before this can happen. (www.atomicinsight.com,2012). For this processto happen a eutectic melting mixture of KOH and NaOH, potassium and sodium hydroxides respectively; the authors explored also the use of other molten oxides, notably, cesium hydroxide, which may prove as a better source for the process. These hydroxides are only molten at higher temperatures, and steam and air or pure nitrogen gas are bubbled through the molten hydroxide s ( in the case of air, carbon dioxide, meaning that with the removal of this gas from the air would be a side benefit of the process, a benefit to the Haber-Bosch process.)The precise stoichiometry of the reaction varies with the conditions, but one form of reaction mentioned by the authors, this done through a controlled environment, is this: N2+ 10H2O → 2NH3+ 5O2+ 7H2 Both pure oxygen and hydrogen are important to the reaction, and goes to show that the reaction offers many potential synergies for the benefit of the scientist. The gases on the right side are not produced as an explosive mixture, because ammonia and hydrogen are formed on one side of the cell, at the cathode, whereas the oxygen is formed at the anode (www.atomicinsight.com).The mixture of cathodic gases, ammonia and hydrogen in the reaction, are easily separated by compression as Lecht found. The overall electrochemical efficiency is quite high compared to other attempts at the electrochemical reduction of nitrogen to ammonia gas, which is around 46%, an efficiency that may well be competitive with Haber-Bosch process ammonia synthesis, however this does not include the heat penalty associated with melting the alkali metal hydroxides and keeping them molten which is the reason nitrogen fixation was proved a commercial disaster when Haber was working, where 38% of the land would be needed and the cost being severely higher, Haber’s process uses only 14% of the land to produce ammonia. What else could aid in the Haber-Bosches super process? A better catalyst. Haber sought for a better catalyst in the 20th century with investigations into uranium. With an understanding of the activity of the key component of the Haber-Bosch process which is the catalyst, could help to better the industrial nitrogen fixation still further from what we previously discussed and remove the need for high temperatures and pressures. Ruthenium, osmium, uranium and cobalt-molybdenum can all catalyse the Haber-Bosch process (ChemWiki.com, 2012), but iron catalysts are cheap. It’s the most commonly used catalyst which was developed more than a century ago and is a potassium-doped iron catalyst. A soluble version of such a catalyst might be even more efficient because it could overcome the rate-limiting step of nitrogen dissociation from a solid catalyst surface, which was demonstrated before. Scientist have found that soluble iron catalysts have proven ineffective for the process in its need to be reducing the N-N triple bond as seen in figure three and also cannot produce large amounts of ammonia for commercial use. Germany has developed a molecular iron complex that can react with (Figure three, The N-N Triple bond, a problem that persist in the formation of an improved haber-bosch process). nitrogen gas in the presence of a potassium reducing agent to generate a complex containing two nitrides bound to the iron and potassium cations which contain a mixed iron (2+/3+) nitride.Germany suggests that the formation of this developed core structure has three iron atoms working together to break the dinitrogen triple bond through a six-electron reduction (NewScientist.com, 2014). The resulting nitride of the reaction then reacts with hydrogen gas to generate a high yield of the product ammonia. Unfortunately, this process leads to the use of the iron and so is not catalytic, a problem for the process as it reduces the yield on ammonia because with an absence of a catalyst the reaction is so slow that virtually no reaction happens in a reasonable time (ChemWiki.com, 2012). The catalyst ensures that the reaction is fast enough for a dynamic equilibrium to be set up within the very short time that the gases are actually in the reactor. Germany’s work on the core provides i mportant clues as to precisely how nitrogen cleavage and N-H bond formation occurs, which might allow them to build a complex that does work catalytically in solution, something that can be further investigated in the future. This is great because it means the Haber-Bosch Process can be simplified and eventually bring a greater yield of product, seeing the growth of ammonia grow in the world. Conclusion: Through economic situations, the Haber-Bosch Process is the most essential to the world, however it’s also the most relevant in terms of the future. Nitrogen Fixation as we looked at can potentially be a competitor to the Haber-Boch Process, due to it’s overall electrochemical efficiency which as stated is quite high in comparison to other attempts at the electrochemical reduction of nitrogen to ammonia gas, it is around 46%, an efficiency that may well be competitive with Haber-Bosch process ammonia synthesis. Unfortunately there is no process being studied in thermodynamics to reduce the heat loss from the process, ChemGuide.uk states that â€Å"A 46% increase is substantial for the future of Ammonia production, but heat loss is an issue for it that so far, can’t be reduced with what we know today†. The next thing we looked at was the catalyst in the current Haber-Bosch Process. Haber dwelled into Uranium but backed out of the idea because of the money, however with the advance we discussed in the study on catalytic effects it’s clear and hypothesises that there is a high possibility that in the future Ruthenium, osmium, uranium and cobalt-molybdenum can all be used in the synthesis of ammonia with a high yield in produce, which is being investigated currently. Advances in the Haber-Bosch Process are our best approach for the future, scientifically and economically, that is until thermodynamics are better understood. Appendix Summary of Le Chatelier’s Principle by www.ChemWiki.ucdavis.edu (1) If the concentration of a reactant is increased, the equilibrium position shifts to use up the added reactants by producing more products. (2) For gaseous reactions, gas pressure is related to the number of gas particles in the system; more gas particles means more gas pressure. Consider a reaction which is accompanied by decrease in number of moles, such as, ammonia synthesis (equation one). Increasing the pressure on this equilibrium system will result in the equilibrium position shifting to reduce the pressure, that is, to the side that has the least number of gas particles. (3) In an endothermic reaction, energy can be considered as a reactant of the reaction while in an exothermic reaction, energy can be considered as a product of the reaction. Consider an exothermic reaction which is accompanied by release of heat, such as ammonia synthesis (equation one). Reducing the temperature of this equilibrium system (which result in taking the heat away) will result in the equilibrium position shifting to increase the temperature (producing more heat), that is, to shift the equilibrium position to the right.

Evaluation of Advert :: essays research papers

Evaluation of Advert My advert uses a woman’s moisturiser and places it along side a man. This is challenging the representation of men because in a normal advert it would of featured a women because it it’s aimed at women.   Ã‚  Ã‚  Ã‚  Ã‚  I started by placing a blue and white gradient background. This is plain and minimalistic but at the same time adding some colour to the advert whereas plain white would have appeared bland. I used blue because it is a very cool colour and is linked with cold colours and ice. I am trying to put across that the product is cool and ‘Smooth’ so cool blues play an important part in the colour scheme. I then added a picture of the product. I placed this in the top right and is quite big. This is to get across the product so there is no confusion in what is being advertised. I surrounded this with a black stroke to make it stand out even more and seeing as the top of the background was nearly white, and having a white bottle the two were hard to tell apart.   Ã‚  Ã‚  Ã‚  Ã‚  I then placed the name of the product next to it in cool, stylish colours but at the same time they contrast the blue and white and stand out really well. I used and effect that is help created by the program I used that appears as the letters are 3d and are ‘gel’ like.   Ã‚  Ã‚  Ã‚  Ã‚  These were then complimented by a ‘And be’ which is the start of the slogan I chose to add. They are in big, Bold and black letters with a white outline to help it, again, stand out. This was placed in the centre of the advert so that they start to read the line and then it is followed through by the rest of the slogan.   Ã‚  Ã‚  Ã‚  Ã‚  The came the rest of the slogan which was ‘Smoooothe’ with too many O’s on purpose to stress the effect. These are in metallic green colours which are bold and vibrant. I stretched the first letter to kind of give the effect of the word zooming in at fast speed.   Ã‚  Ã‚  Ã‚  Ã‚  Then I added a male model in black and white in the bottom left, He has an open, revealing and seducing shirt to attract people.   Ã‚  Ã‚  Ã‚  Ã‚  I then added a bold blue and green border that uses the same gel like effect as the name of product.

Race Ethnicity and Literature Essay

I have had an opportunity to read three great short stories. The short stories were â€Å"The Welcome Table, Country Lovers, and Child of the Americas. † All of them were amazing stories, betraying ethnic challenges, and some responsibilities. I think overall, everyone should read those stories in order to get certain perspective on culture, and understanding on how they lived during the time frame in their life. I also think the short stories provide an understanding in some respects, of how racial divide was apparent during that timeframe. As far as a declarative statement on this matter, I would like to show examples of the literature readings as it correlates with the perspectives of the racial divide, segregation, and overall trials in which ethnic individuals have had to go through. The assertion, I would like to provide is that, short stories can be a direct reflection on time periods that are occurring in life in spite of it being fiction. Our ancestors lived in a time of slavery and segregation. There was no unity between mankind unless the skin color was the same. There was no equality between man and woman and there was no justification to why anyone would be treated superbly unless they were white. It was thought that black people were diseased, filthy and inferior. Over the years, it took people like Dr. Martin Luther King, Jr. , Rosa Parks, and Harriett Tubman to make a statement and help change the future for all other races, not just African Americans. Today, although racism still exists, it is illegal to discriminate against anyone for any reason to include race. The Literary works such as â€Å"Alice Walker’s The Welcome Table, Nadine Gordimer’s Country Lovers, and Aurora Levin’s Morales’s Child of the Americas† give feeling, and meaning to the different angles of racial segregation and acceptance. These literary pieces open one’s eyes and heart to what has been experienced by many if not by one personally. The Welcome Table by Alice Walker is a story about an old, African American woman who is looked down on by the white community. On her way to church, she was stared at with disgust, with pity and with fear. Once inside the church, it was made clear that she didn’t belong and was not welcomed there. â€Å"Under the old woman’s arms they raised their fists, flexed their muscular shoulders, and out she flew through the door, back under the cold blue sky† (Clugston. , 2010)Upon being thrown out, the old woman saw Jesus approaching and soon walked away with him. She walked herself to death and yet no one ever spoke of the ragged old women. No one cared what happened to her for she was just an old black woman who stepped in to the house of God, the God of the white race, a place in which she didn’t belong. It is stories like these that make you wonder of the cruelty that was endured by many in the past. Alice Walker made it clear in her short story the feeling and thought that many had toward African American. Her description of the old woman was strong enough to paint a vivid picture of what the woman looked like. â€Å"She was angular and lean and the color of poor gray Georgia earth, beaten by king cotton and the extreme weather† (Clugston, 2010). African Americans worked harder than everyone else on the farms of the past. They were owned by the white farmers during slavery and even after slavery was abolished, they still were employed by the white farmers. Walker makes it easier to understand that although slavery was no longer, segregation and hatred to all who were African American was still very strong. There was no acceptance from anyone regardless of the fact that most of the white families were taken care of or raised by African Americans. There was no sympathy, just disgust and disapproval. Unlike Walker’s piece, Country Lovers by Nadine Gordimer shows a slightly different side of race and segregation. In Walker’s piece, there was no acceptance, no love, no feeling of mutuality. Gordimer on the other hand, talks about children playing together in the yard and fields. Race having no impact on how they interact, the kids play together and get along like family. As the time goes on and the kids get older, they begin to go their separate ways. The white children are sent off to school while the black children begin to work around the house and farm. A white boy and black girl from the story grow up together as close friends. They establish a relationship that compares to no other. When the boy goes off to school, he continues to stay friends with the girl. As he gets older and he hangs out more with his white school friends, he hides his friendship with his childhood friend. The friendship between the two had bloomed to something more, it had bloomed into a secret love. What would the rest of his family or friends think or say had they known that he loved this girl? A black employee to the boy’s father like in â€Å"The Welcome Table,† black people were looked down and were only good and useful to tend to the fields and the house work. They were not meant for friendship or relationships; they are not accepted as social beings. They are strictly workers. At the end of the story, the sexual and loving relationship that once was, is brought to an end by the birth of a baby that was unwanted and denied by the white boy. He refuses to admit his love and to differ from the world around him. Why wouldn’t he profess his love for this girl now that they have a child together? I believe this piece shows how society plays such a great role in the actions, feelings, and thoughts of humans everywhere. Had racial segregation been something of a distant dream, would the outcome be the same. Why do people act based on the perception and thought of those around them? Race plays a major role in Gordimer’s story. It determines the outcome of the story from start to finish. How many people have gone through a situation of the sort? For those who do not know what it feels like to be discriminated against because of race, this story takes a very personal subject and ties it in emotionally. Many people have experienced love and parenthood. How would one feel if the love of their life denied them in front of everyone because of their skin color? What if their child was denied or killed because of what others would say or do? Losing someone is never easy but to lose someone over something uncontrollable like race, it is heartbreaking. Readers are able to relate and feel what this young black girl is feeling as she grows up and away from the boy she has always loved. The relationship starts as one that everyone can relate to; a story of friends and soon turns in to a heart-felt, pain stricken story of betrayal and solitude. It was not until after the Civil War that segregation became illegal. There were still many states that were fighting for complete desegregation but African Americans were able to do things that their ancestors could only dream (Cozzens, 1995). Although integration of races was put into order by law, people found other ways to show their disapproval for what they believed was the inferior race: African Americans. Political groups formed in retaliation to the integration laws that had been passed and were taking effect. In the 1960’s, following many Civil Rights movements, a group known as the Ku Klux Klan became very active and violent towards who they thought were un-American. This abuse and hatred was towards more than just African Americans, it went towards Jews, Catholics and immigrants as a whole (Newton, 2007) Knowing that African Americans were not the only ones in the world hated by the white American society, Aurora Levin’s Morales’s poem Child of the Americas the acceptance of one’s race regardless of the thoughts of society. In this poem, Morales describes herself as an American, Puerto Rican, Taina, Mestiza, Caribbean, European, African, and altogether, an immigrant (Clugston. , 2010). She goes on to talk about how she lives her life in a certain way particular to each individual race. Each piece lives within her and she is happy and proud of the person she is. In today’s society, many people are not happy with themselves and try to conform to what they feel is socially acceptable. Morales’s poem opens up the hearts and minds to those who are mixed or born outside of the United States. Many feel like outsiders, like they do not belong. Instead of being themselves and being happy whether they get the approval of all or not, many sell themselves short in order to please. I believe Morales’s poem paints a very clear and concise picture across the page. The poem show that no matter what society thinks, one will never be happy or satisfied without being happy or satisfied with oneself. Morales using very distinguishing actions that one could relate to being Hispanic or a â€Å"child of the Americas†. She uses everyday life experiences that many can relate to vice fictional ideas that would make ones imagination do all the work. It is almost as if she was speaking not only for herself but for every Latin American that lives in the United States. â€Å"I was born at the crossroads and I am whole† (Clugston. , 2010). â€Å"Title VII of the Civil Rights Act of 1964 protects individuals against employment discrimination on the bases of race and color, as well as national origin, sex, and religion. Title VII applies to employers with 15 or more employees, including state and local governments. It also applies to employment agencies and to labor organizations, as well as to the federal government† (The U. S. Equal Employment Opportunity Commission, 2011). It is laws like these that keep our country somewhat free from races and cultures being treated as inferior. Although there are many different laws against racism, segregation and discrimination, it still occurs in today’s world. Each literary piece described above is different in many ways. There are underlying factors which give each story its own theme but at the end, race is represented very strongly within them all. Had the world not been so racial divided, would these storied have the same meaning? Would these pieces even exist? Race and how it is looked upon is the main theme that each story has in common. Although unconditional love, self-acceptance and social standing are also a theme within the three pieces, it is hard to look over the common denominator. Many times, writers can write about similar stories but different underlying themes change the way the stories are interpreted and what is taken from the story as a lesson learned. For example, had another write wrote a poem about being mixed in race but being widely accepted or being the popular person in society, the focus would be put on the social life vice the personal acceptance and gratification of being a happy individual that Morales shows in her piece. Had Walker’s piece been focused more towards Jesus and his acceptance of all regardless of race, the outcome of the story may have changed. The story may have revolved on praise and worship vice who treated the old woman poorly and why. As we learn to read and divulge in many different literary works, we learn to notice different themes and meanings behind each piece. Themes like race are very noticeable and very strong themes that get the wheels turning in the mind. Not many people can realize a theme in a story but the three pieces discussed in this paper all have very obvious and very strong themes that anyone and everyone can empathize and relate to. How can one read something of the sort and not relate or imagine feeling? It is nearly impossible especially since it is something that was fought for by many for years on end. It is something that many have witnessed or heard stories about; a part of history that will never be forgotten. Although literary works may be similar in theme or topic they are far from written the same way. The literary pieces discussed are all just as different as they are similar. Each work is written differently, conveys different emotions and reactions and overall expresses a different level of understanding. Point of view differs within each piece and with the difference it makes the reader’s perception of the story different. For example, Morales writes her piece using the first person point of view. It gives the reader a personal insight to what the writer is feeling and trying to express. Third person point of view leaves the readers mind open to visualization of many different things. There are many stories out in the world that touch base with issues such as racism, segregation, and discrimination. Whether in first person or third person; whether fact or fiction, these stories and poems all have share similar meaning and theme. Writers of racial themes put across the pain and chaos that these difference cause. Many people often times fail to see the pain behind things such as discrimination but through symbolism, metaphors, and other key literary terms these feelings, emotions and experiences are brought to light. Race is an issue that many people deal with on a day to day basis regardless what side of the spectrum they are on. Having read each piece of work, I can say that themes in each were very different yet strong and imaginative. A reader can never say that the imagination was not stimulated with the thought and understanding of each piece of work. Each piece establishes a sense of strength, love and personal experience throughout the piece. As a reader, I can say that after reading each piece I felt connected to the characters within whether it is imaginatively or realistically. Racism exists even to this day. We witness it through hate crimes committed in some of what are thought to be the safest places, like schools and churches. The Jena 6 controversy in Louisiana was a situation in which a white student was beaten up by a group of African American students after three nooses were left hanging on a tree where one of the African American students sat the day before. This tree was said to be a hangout for white students only (â€Å"The case of the Jena six: black high school students charged with attempted murder for schoolyard fight after nooses are hung from tree [Radio series episode].,† 2007). This controversy became a national headline in the news because many saw it as African Americans being portrayed as inferior and the root of all evil. People did not see any wrong from anyone else but the African Americans and vice versa. This and other such issues leave people with the feeling that racism and discrimination is something that is among us all and subject to come out when we least expect it. Can literary works like the ones discussed open up the eyes of the readers to the feelings that hatred and racial segregation causes? I believe that each one of these literary works has a strong racial theme and each one can impact a reader in a way that was not expected. As we become strong and more in depth readers, themes like these will become more vibrant and obvious to see. Race and ethnicity is nothing more than an exterior color and difference in geographical location (Hallam, 2004). The authors make it clear that these difference cause lots of separation and heartache. These themes not only educate on historical experience but on what should be put to rest as an unhappy and disapproving issue that is ongoing in society.

Hide and seek by Vernon Scannell Essay

‘Hide and seek’ by Vernon Scannell is about a young, excitable infant playing the childhood game of hide and seek. It begins by revealing the juvenile excitement experienced by a child when playing a game – ‘Call out. Call loud: I’m ready! Come and find me!’ Through the poets use of exclamation marks we can see the child’s joy at partaking in the game. It is exhilarating and fun time for the child, but it is also very competitive. The manner in which he hides shows this competitiveness; he meticulously hides under dirty sacking in the garden shed and makes sure that his feet aren’t ‘sticking out’ . Also when his friends are seeking him, they are portrayed as ‘prowling in’, and ‘whispering at the door’. This further intensifies the degree of competitiveness within the game. However he is determined to win the game, and after a lengthy space of time he thinks, ‘It is time to let them know that you’re the winner’. By know the child is supremely confident that he has emerged the victor, however it only exaggerates his betrayal and feeling of abandonment when he finds out the truth. Finally when the boy victoriously emerges from his hiding place, and shouts ‘I’ve won, I’ve won! Here I am!’ he is greeted by a scene of nothingness -‘The darkening garden watches. Nothing stirs’. His childish dreams of a grand procession in his honour are dashed immediately, and we begin to sympathise with the boy as he tragically realises that he has been betrayed and deserted by his friends. The most important theme explored in ‘Hide and seek’ is the individual status of one human being. The poem asks the contentious question, how much do we really matter? The poet divulges into this topic and comes to the conclusion that we are not individually important in the wider scheme of things than we think. ‘Half-past Two’ by U.A. Fanthorpe concentrates more on the idea of time and the ways in which it governs society. The poem revolves around a child being  punished for doing ‘Something Very Wrong’. The use of capital letters gives the impression that the act committed must have something very serious, and also describes the angered tone of voice that the teacher may have used when admonishing him. However the next line contrasts sharply with these thoughts by saying – ‘(I forget what it was)’. The punishment given by the teacher is to make him stay in the ‘schoolroom till half-past two’. However, the words ‘half-past two’ are meaningless to the boy because ‘She hadn’t taught him Time’, and he was too scared to remind her of that. The boy is always respectful towards the teacher, and their social difference is exaggerated by the capital letter at the beginning of the word ‘She’. The teacher is perceived as a god-like figure to the boy, who has no power or say in any of her imperatives. The unfortunate boy has no comprehension of time and therefore ‘half-past two’ is double-dutch to him. The boy’s definition of time comes from aspects of his own family life – ‘Timeformykisstime’, ‘Gettinguptime’ and ‘TVtime’. The child, although not pre-linguistic, is not practiced in the use of regular time and hence must use time by thinking of things connected with it. His compound ‘time-words’ shows his inability to associate with the ‘alien’ abstract time that the adults in his environment repeatedly use. As a result, he does not know when it is time for him to leave the schoolroom to return home. This causes him to forget that time exists, and he begins to dream about the ‘smell of old chrysanthemums’ and ‘the air outside the window’. This is a typical example of an epiphany, where the boy becomes unimpeded by the constraints of time, shown by the use of the words ‘into ever.’ He is liberated by the bounds of time for a short while, that is until his startled teacher returns to find him still there. The teacher is profusely apologetic and tells him that he can go home. The ensuing stanza is probably the most important – ‘And he never forgot how once by not knowing time/He escaped into the clockless land of ever/ Where time hides tick-less waiting to be born. A feeling of reminiscence is shown by the use of the words ‘he never forgot.’ The ending is particularly affirmative as it shows the happiness felt by the boy as his imagination runs wild and he eludes time into the ‘clockless land of ever.’ The most pertinent theme explored in ‘Half-past Two’ is that of time, and the way it governs our lives. The poem is articulates the adversities of time and contrasts it with the liberty and bliss experienced by the boy when he was freed from time. The cruel aspect is that all human beings eventually run out of time; we get old, lonely and eventually die due to time. Isolation is a major theme within both poems because it affects both boys concerned in a different but dominant way. The child in ‘Hide and Seek’ is purposefully forgotten and is left alone to his own senses: ‘floor is cold’. Isolation is a key element in ‘Half-past two’ because the child in question is forgotten about in detention and he begins to reverie in his own world. It is a more commanding theme in ‘Hide and Seek’ because of the harsh nature in which the boy is abandoned. One of the most foremost similarities in themes between the two poems is that they both concentrate profoundly on greater social forces. This is seen by the use of the words ‘She’ in ‘Half-past two’ and ‘They’ in ‘Hide and Seek’. The boy in ‘Half-past two’ is completely controlled by his authoritative teacher; and one may argue that the ‘prowling’ and ‘whispering’ are quite threatening thus causing the boy to hide because of his fear of society, not simply because he is playing a game. Time is a comparable theme explored in both poems, but more so in ‘Half-past two’. In ‘Hide and Seek’, time symbolically passes to show the transition of friendship to loneliness; and ‘Hide and Seek’ discusses how the world is restrained by the limits of time.

The Animation of Waking Life essays

The Animation of Waking Life essays The Animation of Waking Life Richard Linklater accomplished a vision that he had almost scrapped until the immergence of a new technique in rotoscoped animation. Waking Life is a film infused with the power of animation that takes us through a journey of dreams and makes one question their own reality. The method of animation used was the step to making this powerful piece of cinema a reality and would not have happened without it. Rotoscoping was inventing in 1915 by animation pioneer Max Fleischer. It is a method that takes live action footage and traces over the images to produce very realistic movement. It is because of this tracing method that some feel rotoscoping is a sort of a cheat or easy way out. However, rotoscoping and other forms like it are a way to explore animation and its creativity even further; it allows animators more artistic freedom by saving labor: To not use these labor saving methods and tools would take us back to the days when acetate cells werent invented and you had not only to animate every frame but had to redraw the background every time as well. It was this type of freedom that allowed everyone involved with the piece to create a film that is just as visually stunning as it is narrativly. Director Richard Linklater wanted to bring artist, like painters, who did not necessarily know anything about producing animation and involve them in the process as animators. To accomplish this Linklater enlisted animator Bob Sabiston as art director. Sabiston brought with him his own developed software nicknamed RotoShop. This software was the tool that allowed artists of all animation levels to create their visions. It is a system that allows artists to trace over the video (Quicktime) with Wacom pens and tablets with results that are very close to brush strokes on a canvas. This method is accelerated due to the softwares interpolation system, which automat...

Gallium Spoon Tricks

Gallium Spoon Tricks Gallium is a shiny metal with one property in particular that makes it perfect for science tricks. This element melts just above room temperature (around 30Â °C or 86Â °F), so you can melt it in the palm of your hand, between your fingers, or in a cup of hot water. A classic set-up for gallium tricks is to make or purchase a spoon made from pure gallium. The metal has about the same weight and appearance as stainless steel, plus once you melt the spoon, you can reshape the gallium to use it again and again. Gallium Spoon Materials You need either gallium and a spoon mold or else a gallium spoon. Its a bit more expensive, but if you get the mold, you can make a spoon over and over. Otherwise, youll need to mold the metal by hand to re-use it as a spoon. The Mind-Bending Gallium Spoon Trick This is a classic magician trick in which the trickster rests a gallium spoon on a finger or else rubs it between two fingers, appears to concentrate, and bends the spoon with the power of his mind. Youve got a couple of ways to pull off this trick: Rest the spoon on a finger that you warmed up right before the trick. Easy ways to warm your hand are to hold a cup of hot tea or coffee or simply put your hand under your armpit briefly.Rub a section of the spoon between two fingers. Friction generates heat, which will soften the spoon. The weight of the spoon will cause it to bend. The Disappearing Spoon Trick If you stir a warm or hot cup of liquid with a gallium spoon, the metal melts almost immediately. The spoon disappears into a cup of dark liquid or pools visibly at the bottom of a cup of clear liquid. It behaves much like mercury (a metal that is liquid at room temperature), but gallium is safe to handle. I dont recommend drinking the liquid, though. Gallium isnt particularly toxic, but its not edible.

Awesome Ball Girl and Perception Essay Example for Free

Awesome Ball Girl and Perception Essay In the short video of â€Å"Awesome Ball Girl†, there is a young ball girl working in the field that makes such a great catch, most professionals would not have been able to make. At the start of the video you would think that you are about to see a home run after a great hit, but my eyes were drawn elsewhere; just like the crowd and two teams. This shows the first stage in the perception process: selection. Selection occurs when one or more of your senses are stimulated, where your mind and body help you choose what stimuli to attend to (Floyd 109). Of my five senses, this video affected my vision and my hearing since I was watching a screen; more senses would have been affected if I would have been in the crowd. We do not necessarily make conscious decisions about which stimuli to notice and which to ignore. Research indicates that there are three characteristics that make a particular stimulus more likely to be selected for attention. (Floyd 109) The first characteristic is that something unusual or unexpected will make a stimulus stand out. Second, that repetition or how frequently you have been exposed to something will make it stand out. Third, the intensity of a stimulus will affect how much you take notice to it. From the video â€Å"Awesome Ball Girl†, two of the characteristics that stood out the most for me were repetition and intensity. I do not watch baseball often so since I am not exposed to that sport often, it stood out to me. In addition to not watching that sport often, the intensity of the crowd made me more interested because I knew something big was happening due to hearing the cheering and gasping. By the end of the video, all of my attention was focused on the young ball girl who just made an amazing catch. Once you have noticed a particular stimulus the next step of the perception process is to classify it by organization, the second stage of the perception process. Organization is the process of categorizing information that has been selected for attention – the mind will apply a perceptual schema to it for a mental framework for organizing information (Floyd 109). Perceptual schemas help us organize sensory information in some meaningful way so that we can move forward with the process of perception. There are four types of schema that help to classify the information we notice about people: physical constructs, role constructs, interaction constructs and psychological constructs. (Floyd 110) Physical constructs emphasize appearances and objective characteristics (height, age, ethnicity, body shape) as well as subjective characteristics (attractiveness). Role constructs emphasize social or professional position (teacher, accountant, father, community leader). Interaction constructs emphasize behavior (outgoing, shy, aggressive, sarcastic, considerate). Psychological constructs emphasize thoughts and feelings (angry, insecure, jealous, worried). (Floyd 110) Looking back on watching this video, I feel like I could apply all of these constructs to the young ball girl. She was a younger white female; her appearance was average height for a woman, not tall and not short with an athletic build – which is known to be attractive. The announcer for the game calls her the ball girl as well as the title of the video which gave the role construct. The interaction I could see was that she was a â€Å"go-getter† and that she was not shy about going after the ball that the professional player missed. After the catch, she was walking back to her seat; she seemed insecure and or worried like she was thinking maybe it was a bad idea to catch the ball now that all attention is on her. Stage one, selection, helped me with stage two, organization because I knew what caught my attention. Seeing a girl running down the side of the field, hearing the crowd cheering and the announcer going crazy made me realize that something spectacular was happening even though I don’t watch baseball often. Once my attention was focused on the ball girl, I was able to use the types of schemas to classify the information that my mind noticed. The third and final stage of the perception process is interpretation. Interpretation in the perception process is assigning all of the information from selection and organization and forming a personal meaning. Three factors: experience, knowledge and closeness can all affect how you interpret something that you perceive (Floyd 111). Every person’s interpretations will most likely differ. For me, experience plays the biggest role since I used to play softball. I know how hard it can be to catch a ball at the rear of the outfield, let alone trying to scale a wall before catching the ball; which proves to me that this young ball girl has a lot of talent. To some people that may be avid baseball fans that attend a lot of games, this could be an event they will never forget, but for me, it is just a very impressive video that I will probably potentially forget about due to my lack of interest in baseball. I do not have doubts that this video is not real or accurate. Crazier things happen every day! After going step by step through the perception process, I see a very talented young girl that has the potential to be a great player on a ball team. Awesome Ball Girl and Perception.

Detailed explanations of the IOT (internet of things) and implications Essay

Detailed explanations of the IOT (internet of things) and implications technology - Essay Example This will be made possible through the increased connectivity between the physical items and the virtual world (Mattern & Floerkemeier, 2010). The Internet of Things is not created by a single novel technology. However, it is made up of a variety of technical developments that create the capacity to bridge the existing gap between virtual and physical world. The capacities that would be created include communication and cooperation, addressability, identification, sensing, actuation, embedded information processing, localization and user interfaces (Mattern & Floerkemeier, 2010). The objects through communication and cooperation would have the capabilities to network between each other as well as with the internet sources, and to update their state using data and services. In addressability, the objects have the capacity to be remotely configured and interrogated through effective location and address through discovery. The physical objects will also be uniquely identified. The optically readable bar codes and the Near Field Communication are just a few of the technologies that incapacitate passive objects that lack inbuilt energy resources to be identifiable. With sensing, the objects will be or are equipped with sensors enabling them to collect data, record and interpret it accordingly then forward or reacts to it. They also have actuators for environment manipulation. They have microcontrollers, processors, in addition to storage capacities. By localization, the objects are conscious of their physical locations or better still can be located. With the user interfaces, the objects are able to effectively communicate with people in appropriate and relevant manner. The concept is premised on the trends witnessed towards the end of the 20th century, where there exist gradual advances in communication and information technology, as well as in microelectronics. These changes

Compare the logic of Mill's utilitarianism with what he references as Essay

Compare the logic of Mill's utilitarianism with what he references as its compliance with the golden rule of Jesus of Nazareth - Essay Example The philosophy of utilitarianism is a theory found in the subsection of normative ethics. The theory proposes that every course of action taken by an individual is governed by the outcome of the result. In most cases, as the theory proposes, the action is justifiable if it has a positive impact to the lifestyle of an individual. The rationale behind this impression made by the theory is based on the fact that if a specific course of action makes one happy then the action is justifiable. The action may not fall in line with the ethics of the society but it is valid in the theory of utilitarianism. Such justifications are what that make the theory dismissed by most people in the society. This is because the members of the society hold high levels of ethics in relation to the action of different individuals. As long as a specific course of action negatively affects the lifestyle of another person, then the action should be considered as unjustifiable and unethical. Basically, utilitaria nism is a self centered concept that focuses on the on the impact of the action on the person taking the action (Meredith 2011). It tends to overlook the impact of the action to the recipient. ... The comparison of the theory to this rule to the theory of utilitarianism shows that the two concepts are in line with each other. This is based on the fact that Jesus proposes that one should unto others what he/she would like others do unto them. In this case one would tend to do unto others things that bring happiness. In this case, the course of action taken by an individual would be focused on the impact that the action has on personal life. Therefore, if a specific action would evoke feelings of happiness to oneself, the person would tend to take the course of action towards the people around him/her with the rationale that he/she would have wanted the same course of action to be directed towards his personal life. On the concept of love your neighbor as you love yourself, the same rationale applies. This is where one would engage in actions that show love to those around him because of the sense that it is the same thing that he or she would want from the person affected by th e action. Utilitarianism is solely focused on the maximization of happiness to the lifestyle of an individual. This is the base line for any course of action taken by an individual. The theory may appear to be self centered because the actions of an individual are not focused on the affected parties by the action. The theory’s main focus is on the lifestyle of the person engaging in the act. Therefore, the affected party by the course of action is not of great significance in the theory. This therefore is the reason as to why the theory is dismissed by most members of the society because it only focuses on one side for a specific course of action taken by an individual. Many societies

The Evolution of Skateboard Photography Essay Example | Topics and Well Written Essays - 750 words

The Evolution of Skateboard Photography - Essay Example llenweber 16). A common fact is that skateboarding has evolved from just another hobby to an internationally recognized sport. It is no longer considered to be a preserve of daredevils and adolescents who seek a way to vent their frustrations. For instance, in 1990, people used to skateboard mainly in parks and on the streets (if they found the opportunity to). Skateboarders and their fans then decided that they needed to shed the bad image that was associated with the hobby and turn it into something more appealing and enriching not just to them but also their fans. Eventually, the various skateboarding associations decided that they would market their hobby as a sport by growing it from the community. They established various skateboarding competitions in different neighborhoods different states in America and within no time the trend had caught on. Every neighborhood wanted to have a skateboarding association cum team, and this made the competition stiffer. A short time after this , the various stakeholders decided to make the participation worthwhile by offering prizes to the best performers. They sought financial assistance from local companies and community-based organizations (CBOs) who recognized it as a way of getting young people off the streets and giving them something to do and look forward to. Many young people sat up and took notice, and eventually most of them decided to join this latest ‘trend†. Within a short time, there were skateboarding championships being held in various states and soon after a national championship was established. Now, it is common knowledge that by the time there is a national championship anywhere (especially in a country like the United States), it means that a sport or hobby has garnered enough attention to warrant such a move (Wu?llenweber 26). Firms started tapping into this new frenzy in order to use it as an advertising avenue (it was particularly strategic because of its popularity among young people) . Through advertising, those companies managed to get the media to cover or even mention skateboarding. By 2009, we had professional skateboarders who supported themselves using the financial benefits they incurred from skateboarding. They were earning thousands of dollars by doing something they loved, and the media had no option but to take notice and accommodate this new sport. Now we have the World Cup of Skateboarding, a global skateboarding federation that organizes the formal World Championships of Skateboarding series that is held in many cities across the world (Bolster & Gesmer 12).

Summary An Economic way of looking at life by Gary Becker Essay

Summary An Economic way of looking at life by Gary Becker - Essay Example Economic way of looking at life helps individuals to know moral pathways and how to be ethical in economics. In chapter 7, social issues that are discussed are termed as labor supply, which in it you find household production, the family, and the life cycle which can be well analyzed by economic way of looking at life. In making household decisions, certain factors have to be in mind. Some of these factors are, the economy, time, income and individuals involved. In household decision making, one of the key attribute is the size. For instance the size of the family and number of children dictate the economic way of living of that family. Often, women in society have a role in bearing and raising a certain number of children and carrying out farm works as opposed to men who work in outside jobs in various offices. Economic analysis of this kind of decision shows that the labor force is low compared to the size of the family. This is because, the income from the couple would be more compared to when only the male individual is working. If the latter is used it would mean poor living standards as the family is growing. As regards to whether families uses more by consuming purchased goods as opposed to home made goods also differs if we analyze using our knowledge on economic way of looking at life. Although there is no such a big difference between the two, if things such as labor and the time spent to produce the home made goods are considered, economic wise consuming household good will carry the day since leisure is achieved and no supervision when producing them. In a later age, household decision on when to retire comes in. The topic about taking care of yet grown up children and on the other hand, older children taking care of the aged parents is dominant. These two are interconnected and each of them is crucial and important. Analysis of this economically

Methods of Study in Economics Essay Example for Free

Methods of Study in Economics Essay This method is also called as abstract, analytical and priority method. Under this method, laws are deduced in a logical manner. On the basis of certain fundamental assumptions or accepted axioms (principles) or truths which have been established and handed down from generation to generation, the required conclusions are found out. This method is called as abstract since it is based on abstract reasoning and not actual facts. However, actual situation may differ from what deductive logic suggests. For example, it is assumed that the man is rational and on the basis of this it is deduced that he will buy cheap and sell dear ones. However, in actual situation this may not happen because of the absence of proper knowledge and market conditions. The principle steps in the process of deriving economic generalizations through deductive logic are: 1.perception of the problem; 2.defining the technical terms and making the appropriate assumptions; 3.deducing hypothesis and; 4.testing of hypothesis deduced. Through the use of deductive method, many theories and generalizations have been established in economics. It is called as inverse relationship between the price and quantity demanded, the direct relationship between the price and quantity supplied etc. However, this method also suffers from certain handicaps such as (i) assumptions generally turn out to be untrue or partially true; (ii) valid conclusions cannot be drawn in the absence of proper knowledge of the whole situation and (iii) it is dangerous to claim universal validity for the economic generalizations so deduced. Inductive method: According to this method, conclusions are drawn on the basis of collection and analysis of the facts which are relevant to the inquiry. The logic in this case proceeds from the particular to the general. The generalizations are based on observation of individual examples. The principle steps in this method are †¢Perception of the problem; †¢Collection, classification and analysis of data by using appropriate statistical techniques; †¢Finding out the reasons for the relationship established through statistical analysis and to set rules for the verification of the principles. Many researches in macroeconomics have been obtained through inductive method such as principle of acceleration describing the factors which determine investment in an economy, the nature of consumption function describing the relationship between income and consumption etc. Inductive method is increasingly being used on account of the under mentioned facts: †¢Statistical induction leading to precise, exact and measurable conclusions; †¢It underlines the importance of relativity of economic laws and †¢It shows that generalizations are valid only under certain conditions. †¢However, this method suffers from †¢Risk of hurried conclusions having being drawn from an insufficient number of facts; †¢Difficulties involved in the collection of facts; †¢The fact that observation and experimentation have very limited application in a science that deals with human activities.

Definitions of Styles and Learning Styles

Definitions of Styles and Learning Styles 2.1.1.1 Definitions of Styles and Learning Styles Styles Before reviewing the literature of learning styles, it is necessary to know the definition of styles. The concept of styles was first put forward by cognitive psychologists. Brown (2002: 104) defines style as a term that refers to consistent and rather enduring tendencies or preferences within an individual. Therefore, styles are those general characteristics of intellectual functioning (and personality type, as well) that especially pertain to one as an individual, that differentiate one from someone else. Learning Styles Regarding studies of learning styles, the most serious problem is the confusion of its definitions. In the past two decades, the learning styles has been used in various and sometimes confusing ways in the literature. It is very common to hear different opinions on its definitions based on different findings in this comparatively new research field of learning styles, for each study defines it from particular perspectives. However, there is not an agree-upon definition of learning styles. Learning styles can be defined in the following ways. Keefe (1979, cited in Brown, 2002:10) defines learning styles as the characteristic cognitive, affective and physiological behaviors that serve as relatively stable indicators of how learners perceive, interact with and respond to the learning environment. Dunn et al. (1978:11) defines learning styles as the way in which each person absorbs and retains information and/or skills; regardless of how that process is described, it is dramatically different for each person. Sims Sims (1990, cited in Reid, 2002) put forward that learning styles are typical ways a person behaves, feels, and processes information in learning situations. Therefore, learning style is demonstrated in that pattern of behavior and performance by which an individual approaches educational experience. Oxford et al. (1991) briefly defines the learning style as the general approaches students used to learn a new subject or tackle a new problem. Tan Dingliang (1995: 12) defines learning styles as: the way that a learner often adopts in the learning process, which includes the learning strategies that have been stabilized within a learner, the preference of some teaching stimuli and learning tendency. Reid (1995) summarizes definitions of learning styles as internally based characteristics of individuals for the intake or understanding of new information. Essentially learning styles are based upon how a person perceives and processes information to facilitate learning. 2.1.2 Categories of Learning Styles Confusion also exists in the literature on categories of learning styles for many same or similar factors researched under the same name. Reid (1995) divides learning-style research into three major categories: cognitive styles, sensory learning styles, and personality learning styles. 2.1.2.1 Cognitive Learning Styles Cognitive learning styles which include field-independent/field-dependent, analytic/global, reflective/impulsive learning styles, and Kolb experiential learning model, belong to the aspects of psychology. Among them researches on field -independent/field-dependent (FI/FD) attract the most attention of SLA domain (Ellis, 1994). According to Reid (1995), field-independent learners learn more effectively step by step, or sequentially, beginning with analyzing facts and proceeding to ideas. They see the trees instead of the forest; whereas field-dependent (field-sensitive) learners learn more effectively in contexts, holistically, intuitively, and are especially sensitive to human relationships and interactions. They see the forest instead of the trees. Chapelle (1995) explains that FI/FD refers to how people perceive and memorize information. Reid (1995) defines that analytic learners learn more effectively individually; prefer setting own goals, and respond to a sequential, linear, step-by-step presentation of materials; whereas global (relational) learners learn more effectively through concrete experience, and by interactions with others. According to Reid (1995), if learners can learn more effectively given time to consider options before responding, they are reflective learners; and they are often more accurate language learners; whereas if learners can learn more effectively being able to respond immediately and to take risks, they are impulsive learners; and they are often more fluent language learners. 2.1.2.2 Sensory Learning Styles According to Reid (1995), sensory learning styles include two dimensions: perceptual learning styles and environmental learning styles. Perceptual learning styles contain four types of learning styles which are auditory, visual, tactile and kinesthetic styles. Auditory learners learn more effectively through the ears; visual learners learn more effectively through the eyes (seeing); tactile learners learn more effectively through touch (hands-on); kinesthetic learners learn more effective through concrete complete body experiences (whole-body movement). Physical and sociological styles belong to the environmental learning styles. Physical learners learn more effectively when such variables as temperature, sound, light, food, mobility, time, and classroom/study arrangement are considered. Sociological learners learn more effectively when such variables as group, individual, pair and team work, or levels of teacher authority are considered. 2.1.2.3 Affective/Temperament Learning Styles Learning styles of this type are based on affect, personality, tolerance of ambiguity and brain hemisphere. Myer and Briggs (1987, cited in Reid, 1995) report that affective and personality factors influence learners learning styles a great deal. Mayer-Briggs team tested four dichotomous styles of functioning in their Mayer and Briggs Temperament Styles (MBTI) which include extraversion-introversion, sensing-perception, thinking-feeling, and judging-perceiving. According to Reid (1995), extroverted and introverted styles belong to extraversion-introversion. Extroverted learner learns more effectively through concrete experience, contract with the outside world, and relationships with others; whereas introverted learner learns more effectively in individual, independent situations that are more involved with ideas and concepts. Sensing-perception contains sensing and perception styles. Sensing learner learns more effectively from reports of observable facts and happenings; prefers physical, sense-based input. Conversely, perception learner learns more effectively from meaningful experiences and from relationships with others. In thinking-feeling styles, thinking learner learns more effectively from impersonal circumstances and logical consequence; whereas feeling learner learns more effectively from personalized circumstances and social values. And in judging-perceiving styles, judging learner learns more effectively by reflection, and analy sis, and processes that involve closure; conversely, perceiving learner learns more effectively through negotiation, feeling, and inductive processes that postpone closure. Reid (1995) suggests that tolerance of ambiguity styles also belong to the affective/temperament learning styles. Ambiguity-tolerant learner learns more effectively when opportunities for experiment and risk, as well as interaction, are present; whereas ambiguity-intolerant learners learns more effectively when in less flexible, less risky, more structured situations. Reid (1995) also claims that whether the learner is left-brained or right-brained will influence learners learning styles. Left-brained learners tend toward visual, analytic, reflective, self-reliant learning; conversely, right-brained learners tend toward auditory, global/relational, impulsive, interactive learning. 2.1.3.1 Sensory Learning Styles Visual styles Visual students enjoy reading and they prefer material in a classroom environment to be presented in a visual format such as books, board work, and handouts. Auditory styles Auditory students enjoy lectures, conversations and oral directions. They prefer material in a classroom environment that is presented as auditory input such as radio, oral instruction, oral communication and audiotape. Hands-on styles Hands-on students like lots of movement and enjoy working with collages, flashcards, and tangible objects. They prefer to be physically involved with tasks, tending to prefer activities such as Total physical Response (TPR) and role-play. 2.1.3.3 Personality Learning Styles Extroversion/Introversion The dimension of styles particularly influences classroom management, especially grouping of students. Extroverted students perform most productively in a group environment, enjoying activities that involve other students, such as role-play, conversation and other interaction favoring social goals as opposed to impersonal rewards. Conversely, introverted students are stimulated most by their own inner world of ideas and feelings. They like working alone or else in a pair with someone they know well. They dislike lots of continuous group work in the ESL/EFL classroom. This contrast is somewhat similar to the categories of group/individual style made by Reid (1987). In conclusion, according to Reid (1995), the role of learning styles in foreign language learning has some fundamentals of learning styles. She claims that learning styles in the ESL/EFL classrooms is based on six hypotheses: Every person, students and teachers alike, has a learning style and learning strengths and weaknesses; Learning styles are often described as opposite, but actually they exist on wide continuum; Learning styles are value-neutral; that is, no one style is better than others (but it is true that there are students with some learning styles work better than those with some other learning styles); Students must be encouraged to stretch their learning styles so that they will be more empowered in a variety of learning situations; Students strategies are often linked to their learning styles; (6) Teachers should allow their students to become aware of their learning strengths and weaknesses.

Ethnicity :: Personal Narrative Racial Papers

Ethnicity While I was first contemplating this project, I was sitting on my older-than-the-hills brown couch in my apartment. My roommate, Michelle, plopped on the couch opposite me and asked, â€Å"What do you want to do for lunch?† â€Å"I dunno,† I responded while channel surfing through the five channels we receive. â€Å"Let’s go out and try something new,† she said daringly. I thought to myself, hmm, I could do a project and eat out at the same time? â€Å"Ok, where should we go?† Suddenly, as if it was a sign from above, a commercial for Santa Lucia’s, the Greek restaurant in town, appeared on the television. Instantly, we knew it was the place to go. â€Å"Good Better Best, Never Let it Rest, Until the Good Becomes Better and the Better Becomes the Best,† the commercial kept echoing in my head on the way there-wait, no that was my roommate who would not quit repeating Santa Lucia’s motto. On the way there we looked at each other and said simultaneously, â€Å"Should we have dressed up for it?† â€Å"Well,† I said, â€Å"on the commercial it doesn’t look like too classy of a place. I think we are fine.† â€Å"Good, I hope so,† said Michelle as she looked down at our jeans and t-shirts. Our hopes were confirmed as we pulled into the parking lot of the restaurant, which is tucked away in the corner behind West Park Auto Plaza. There were beer signs littering the windows. It could not be that classy of a place. Right? â€Å"What do they serve here, Heather? Am I going to like it?† asked Michelle, who by the way is the pickiest eater in the world. â€Å"I hope so,† I responded as we entered the building. â€Å"Uh-oh. Maybe we should have dressed up,† I thought to myself out loud for a moment while taking in the view. When you enter from the street into the building it’s like you are entering a completely different world. The lighting is dim. Tables for two, four, six and eight are scattered throughout the room in the usual non-smoking and smoking sections. The tables themselves are unique looking. The wooden tables and chairs are set on the plush carpet. The black tablecloths are topped with a shiny glass cover. The tables are set with silverware and wine glasses with a napkin creatively set inside. The one thing that caught my eye was the statue and the fountain.

Loyset Compère Motets (Orlando Consort) :: Composer Music Musical Musician Essays

Loyset Compà ¨re Motets (Orlando Consort) Loyset Compere, an accomplished yet not very well-known composer of the 15th century, has been neglected as a figure in musical history. Historians through the ages have somehow left him out of most of their writings. Therefore, as modern researchers and discoverers, we have very little resources from which to gather information about Compere. In fact, even his date and place of birth are argued upon by historians. Thus, our study is limited to what we see on the pages of his music and what we glean from the music we hear (MCD 1490, Carapetyan). It is believed that Compere wrote some motets for the French Royal court during his years there. Among these motets was the canon Asperges me Domine, a beautiful four-part canon in 4ths. It was written sometime between 1500-1505, although the exact date is not known for sure. This was towards the end of Compere's life when his experience as a composer was at its peak (Carapetyan and Finscher 255). The canon was a popular musical form of this period; however, a canon in 4ths was not. There are many aspects of this piece that make listening to it fascinating. The following pages will explore the intrigues of Aperges me Domine including its structure and its ties between music and text. Asperges me Domine is broken up into three sections, each section starting with a solo chant from the superius voice. After the chant, each section then continues with a canon starting in one of the four voice parts. The first section, which we will call section I, starts with the opening chant and ends with a strong cadence on measure 18. It uses six overlapping phrases to express the first sentence of text. The first canon starts with the bassus voice, but the starting voice changes throughout the piece. However, each canon, throughout, is sung at the fourth. There are four strong cadences, m. 2, m. 5, m.10, and m. 18, each marking the end of a thought in the text. There are also many other places that exhibit a kind of pseudo-cadence where the modern ear expects to hear a resolution, and the resolution is reached; however, movement among the middle parts nullifies the effect of the cadence. For example, in m. 12, the superius and the bassus parts seem to reach a cadence point, but the tenor and alto parts continue to move catching the listeners attention away from the cadence point.

The Best Tour I’ve Ever Had

As a 11 years old kid, I have had many vacations before. Those vacations include trips to Spain, Australia, Canada, Japan, Korea and many other places. Pictures of volcanoes, oceans, Islands were taken. Each of them represents an amazing vacation that I had. However, none of them can be compared to the â€Å"Winter vacation, the one to Alaska by cruise. This trip left me a fantastic memory. I favor the vacation to Alaska. We had a chance to watch the whales in the ocean. I had desired to watch the whales in Juneau. I was so excited that I almost dropped my telescope into the deep, blue water. I could see a whale flipping in the water.It plashed the waves with its huge, flat tail and dived into the water. The captain drove the boat closer to the whales. One of them Jumped out in a curved position. As it dived into the water, its tails waved back and forth. Water was splashed out on the top of a blue whale's head. Looking there from the telescope, it looked like a fountain. This trip was extra-entertaining because I went dog sledding with the huskies. I remember the cold day when snow was falling from the sky, piling up on the ground. My parents and I went to a snow-covered mountain at Skagway. We went there by helicopter. The dog-sledding part was so entertaining.At first I held on to the handles steadily, but soon I became bored. I stuck my feet into the snow. I didn't notice it when the musher speeded up the sled. I fell on my belly. I held on to the handles with my hand and screamed. It was an enjoyable experience even though I got myself totally wet. Another beauty of this trip is that I went to Alaska by cruise. Sometimes on a vacation, I would want to sit back and rest. The cruise provided dfferent shows and exercises for us. Basically every night I went to watch a show or a concert. There was a pool on the 12th deck. I could go swimming any time I wanted to.The freezing cold water penetrated me, but I still went swimming once a while. I had a relaxing ti me on board. This trip was absolutely enjoyable. I never had such a trip that satisfied me. I'll never forget the excitement of whale watching, dog sledding and the relaxing time on board. This is definitely the best trip ever! The Best Tour I've Ever Had By Limandan volcanoes, oceans, islands were taken. Each of them represents an amazing vacation that I had. However, none of them can be compared to the â€Å"Winter† vacation, the one I would want to sit back and rest. The cruise provided different shows and exercises

Biological Effects Of Radiation Environmental Sciences Essay

Radiation describes a procedure in which energetic atoms or moving ridges travel through a medium or infinite. There are two distinguishable types of radiation ; ionising and non-ionizing. The word radiation is normally used in mention to ionising radiation merely holding sufficient energy to ionise an atom but it may besides mention to non-ionizing radiation illustration like wireless moving ridges or seeable visible radiation. The energy radiates travels outward in consecutive lines in all waies from its beginning. This geometry of course leads to a system of measuring and physical that is every bit applicable to all types of radiation. Both ionising and non-ionizing radiation can be harmful to beings and can ensue in alterations to the natural environment. Radiation with sufficiently high energy can ionise atoms. Most frequently, this occurs when an negatron is stripped from an negatron shell, which leaves the atom with a net positive charge. Because cells are made of atoms, this ionisation can ensue in malignant neoplastic disease. An single cell is made of millions of atoms. The chance of ionising radiation doing malignant neoplastic disease is dependent upon the dose rate of the radiation and the sensitiveness of the being being irradiated. Alpha atoms, Beta atoms, Gamma and X-Ray radiation, and Neutrons may all be accelerated to a high plenty energy to ionise atoms. Alpha atom: In alpha atom, the self-generated procedure of emanation of an alpha atom from a radioactive karyon. Alpha atom is by and large termed as alpha decay. An alpha atom is emitted by a heavy karyon. The karyon, called parent karyon has a really big internal energy and is unstable. An alpha atom is a He nucleus holding two protons and two neutrons. When two negatrons revolving around the karyon of He atom are knocked out wholly, we have double ionized He atom known as alpha atom. Beta atom: a beta-particle is a fast moving negatron. The self-generated procedure of emanation of beta-particle from a radioactive karyon is called beta decay. Beta decay is of three types: beta-minus, beta-plus, and electron gaining control. Beta-minus: beta-minus is like an negatron. It is surprising that nucleus contains no negatron, so a karyon can breathe negatron. In the neutron inside the karyon is converted in to a proton and an negatron like atom. This negatron like atom is emitted by the karyon during beta-decay. In beta-minus decay, neutron in the karyon is converted in to a proton and a beta-minus atom is emitted so that the ratio of neutron to proton lessenings and therefore the nucleus becomes stable. Beta-plus: In a beta-plus decay, a proton is converted in to a neutron and a antielectron is emitted if a karyon has more protons than neutrons. Electron gaining control: In negatron gaining control, nucleus absorbs one of the interior negatrons go arounding around it and hence a atomic proton becomes a neutron and a neutrino is emitted. Electron gaining control is comparable with a antielectron emanation as the procedures lead to the same atomic transmutation. However, in negatron gaining control occurs more often than antielectron emanation in heavy elements. This is because the orbits of negatrons in heavy elements have same radii and hence orbital negatrons are really near to the karyon. Gamma beam: Gamma beams are the high energy packages of electromagnetic radiation. Gamma radiations have high energy photons. They do non hold any charge and their comparative remainder mass is zero. Gamma-decay it is the self-generated procedure of emanation of high energy photon from a radioactive karyon. When a radioactive karyon emits a beta atom, the girl karyon is excited to the higher energy province. This aroused karyon beams are emitted by the girl nucleus so it is clear that the emanation of gamma beams follows the emanation of alpha or beta atom.Non ionising radiation:Non-ionizing signifiers of radiation on life tissue have merely late been studied. Alternatively of bring forthing charged ions when go throughing through affair, the electromagnetic radiation has sufficient energy to alter merely the rotational, quiver or electronic valency constellations of molecules and atoms. However, different biological effects are observed for different types of non-ionizing radiation Radio moving ridges: Radio moving ridges whose wavelengths range from than 10^4m to 0.1m, are the consequence of charges speed uping through carry oning wires. They are generated by such electronic devices as LC oscillators are used in wireless and telecasting communicating system. Infrared beams: Infrared radiations have wavelength runing from about 0.3m to 10^ -4m and besides generated by the electronic devices. The infrared radiation energy absorbed by a substance as internal energy because the energy agitates the object ‘s atoms, increasing their quiver or translational gesture, which consequences temperature increases. Infrared radiation has practical and scientific application in many countries, including physical therapy, infrared radiation picture taking, and quiver spectrometry. Ultraviolet radiation: Ultraviolet radiation screen wavelength runing from about 4X10^4m to 6X10^-10m. The Sun is an of import beginning of ultraviolet radiation visible radiation, which is the chief cause of tan. Sunscreen locations are crystalline to seeable visible radiation but greater per centum of UV visible radiation absorbed. Ultraviolet beams have besides been implicated I the formation of cataracts. Most of the UV visible radiation from the Sun is absorbed by ozone molecules in the Earth upper ambiance, in a bed called stratosphere. This ozone shield converts lethal high energy UV radiation to infrared radiation, which in bends warm the stratosphere. X raies: X raies have the scope from approximately10^-8 to 10^-12m. The most common beginning of X raies is halting of high energy negatrons upon the pelting a metal mark. X raies are used as nosologies tool in medical specialty and as the intervention for certain signifiers of malignant neoplastic disease. Because X raies can damage or destruct living tissue and being, attention must be taken avoid necessary exposure or over-exposure. X raies are besides used in the survey of crystal construction because x-rays wavelengths are comparable to the atomic separation distance in solids. Electromagnetic radiation: The wave nature of electromagnetic radiation explains assorted phenomena like intervention, diffraction and polarisation. However, wave nature of electromagnetic radiation, could explicate phenomena like photoelectric consequence, Compton Effect. The cathode rays consist of negative charged atoms called negatrons which are the component of an atom and therefore the component of affair. Harmonizing to the construct of radiation illustration light moving ridge ‘s wireless moving ridges, X raies, microwaves etc. are assumed to transport energy in packages or packages known as photons or quanta.Biological consequence of radiation:In biological consequence of radiation, there are many unsafe effects of our wellness and organic structure. Biological effects of radiation are typically can be divided into two classs. The first category consist of exposure to high doses of radiation over shots period of clip bring forthing ague or short term effects. The 2nd class represents exposure to low doses of radiation over an drawn-out period of clip bring forthing chronic or long term effects. High dosage ( acute ) : high doses tend to kill cells, while low doses tend to damage or alter them. High doses can kill so many cells that tissues and variety meats are damaged. This is bend may do a rapid whole organic structure response frequently called the ague radiation syndrome ( ARS ) . Low doses ( chronic ) : low doses spread out over long periods of clip do n't do an immediate job to any organic structure organ. The effects of low doses of radiation occur at the degree of the cell, and the consequences may non be observed for many old ages. Although we tend to tie in high doses of radiation with ruinous events such as atomic arms detonations, there have been documented instances of persons deceasing from exposures to high doses of radiation ensuing from tragic events. High effects of radiation: high effects of radiation are skin Burnss, hair loss, asepsis, cataracts. Effectss of skin include ( blushing like tan ) , dry ( skining ) , and moist ( vesicating ) . Skin effects are more likely to happen with exposure to moo energy gamma, x-ray, or beta radiation. Most of the energy of the radiation sedimentation in the skin surface. The dosage required for erythematic to happen is comparatively high, in surplus of 300 radiations. Blistering requires a dosage in surplus of 1,200 radiations. Hair loss, besides called epilation, is similar to clamber effects and can happen after acute doses of about 500 radiations. Asepsis can be impermanent or lasting in males, depending upon the doses. To bring forth lasting asepsis, a dosage in surplus of 400 radiations is required to the generative variety meats. Cataracts ( a clouding of the lens of the oculus ) appear to hold a threshold about 200 radiations. Neutrons are particularly effectual in bring forthing cataracts, because the oculus has high H2O content, which is peculiarly effectual in halting neutrons.High dose effects:Dose ( radiation ) consequence observed15-25 blood count alterations. 50 blood count alteration in single. 100 Vomiting ( threshold ) . 150 Death ( threshold ) .Classs of effects of exposure to low doses of radiation:There are three general classs of effects ensuing from exposure to low doses of radiation. These are: Familial: the consequence is suffered by the progeny of the person exposed. Bodily: the consequence is chiefly suffered by the person exposed. Since malignant neoplastic disease is the primary consequence, it is sometimes called the carcinogenic consequence. In-utero: some erroneously consider this to be a familial effect of radiation exposure, because the consequence, suffered by a development is after birth. However, this is really a particular instance of the bodily consequence, since the embryo is the 1 to the radiation. Radiation hazard: the approximative hazards for the three chief effects to degree of radiation are: In familial consequence, hazard from 1 paradoxical sleep of radiation exposure to the generative variety meats about 50 to 1,000 clip ‘s less than self-generated hazard for assorted anomalousnesss. In bodily consequence, for radiation induced malignant neoplastic disease, the hazard estimation is developing any type of malignant neoplastic disease. However non all malignant neoplastic diseases are associated with exposure to radiation. The hazard from deceasing from radiation induced malignant neoplastic disease is about one half the hazard of acquiring the malignant neoplastic disease. In utero: Spontaneous hazards of foetal abnormalcies are about 5 to 30 times greater than hazard of exposure to 1 paradoxical sleep radiation. However, the hazard of child goon malignant neoplastic disease from exposure in utero is about the same as the hazard to grownups exposed to radiation exposures. Linear no-threshold hazard theoretical account: general consensus among experts is that some radiation dosage by a additive, no threshold theoretical account. This theoretical account is accepted by the NRC since it appears to be most conservative. Linear: an addition in dose grownups in a relative addition in hazard. No-threshold: any dosage, no affair how little, produces some hazard. The hazard does non get down at 0 because there is some hazard of malignant neoplastic disease, even with no occupational exposure. Exposure to radiation is warrant of injury. However, because of the additive, no-threshold theoretical account, more exposure means more hazard, and there is no dosage of radiation so little that it will non hold some consequence.Effects OF RADIATION ON CELLSIonizing radiation absorbed by human tissue has adequate energy to take negatrons from the atoms that make up molecules of the tissue. When the negatron that was shared by the two atoms to organize a molecular bond is dislodged by ionising radiation, the bond is broken and therefore, the molecule falls apart. This is a basic theoretical account for understanding radiation harm. When ionising radiation interacts with cells, it may or may non strike a critical portion of the cell. We consider the chromosomes to be the most critical portion of the cell since they contain the familial information and ins tructions required for the cell to execute its map and to do transcripts of it for reproduction intents. Besides, there are really effectual fix mechanisms at work invariably which fix cellular harm – including chromosome harm.Uses of radiation: Nuclear natural philosophies application are highly widespread in fabrication, medical specialty in biological science, we present a few of these application and implicit in theories back uping them. Tracing: Radioactive tracers are used to track chemicals take parting in assorted reactions. One of the most valuable utilizations of radioactive tracers in medical specialty. For illustration, I, a food needed by the human organic structure, is obtained mostly through consumption of iodinated salt and sea nutrient. Radiation therapy: Radiation causes much harm to quickly spliting cells. Therefore, it is utile in malignant neoplastic disease intervention because tumour cells divide highly quickly. Several mechanisms can be used to present radiation to a tumour. In some instances, a narrow beam of X ray or radiation from a beginning such as 60co is used. In other state of affairs, thin radioactive acerate leafs called seeds are implanted in the cancerous tissue. The radioactive isotope 131I is used to handle malignant neoplastic disease of the thyroid. Black organic structure radiation: An object at any temperature emits electromagnetic moving ridges in the signifier of thermic radiation from its surface. The features of this radiation depend on the temperature and belongingss of the object ‘s surface. Thermal radiation originates from accelerated charged atoms in the atoms near the surface of the object ; those charged atoms emit radiation much as little aerials do. The thermally radiation agitated atoms can hold a distribution of energies, which accounts for the uninterrupted spectrum of radiation emitted by the object. The basic job was in understanding the ascertained distribution of wavelengths in the radiation emitted by a black organic structure. A black organic structure is an ideal system that absorbs all radiation incidents on it. The electromagnetic radiation emitted by the black organic structure is called black body radiation. Radiation harm: Radiation harm means that electromagnetic is all about in the signifier of wireless moving ridges, microwaves, light moving ridges so on. The grade and type of harm depend on several factors, including the type and energy of the radiation and belongingss of the affair. Radiation harm in biological being is chiefly due to ionization effects in cells. A cell ‘s normal operation may be disrupted when extremely reactive ions are formed as the consequence of ionising radiation. Large those of radiation are particularly unsafe because harm to a great figure of molecules in a cell may do to decease. In biological systems, it is common to divide radiation harm in two classs: bodily harm and familial harm. Bodily harm is that associated with any organic structure cell except the generative cells. Bodily harm can take to malignant neoplastic disease or can earnestly change the features of specific being. Familial harm affects merely generative cells. Damage to the cistrons in generative cells can take to faulty cells. It is of import to be the aware of the consequence of nosologies interventions, such as X raies and other signifiers of radiation exposure, and to equilibrate the important benefits of intervention with the detrimental effects. Damage caused by the radiation besides depends on the radiation ‘s perforating power. Alpha particles cause extended harm, but penetrate merely to shoal deepness in a stuff due to strength interaction with other charged atoms. Neutrons do non interact via the electric force and hence penetrate deeper, doing important harm. Gamma beams are high energy photons that can do serve harm, but frequently pass through affair without interactions. For example- a given dosage of alpha atom causes approximately 10 times more biological harm produced by radiation than equal dosage of X raies. The RBE ( comparative biological effectivity ) factor for a given type of radiation is the figure of rads of X ray or gamma radiation that produces the same biological harm as 1-rad of the radiation is being used. Radiation sensors: Atoms go throughing through affair interact with the affair in several ways. The atoms can, for example- ionize atoms, spread from atoms, or be absorbed by atoms. Radiation sensors exploit these interactions to let a measuring of the atom ‘s energy, impulse, or alteration and sometimes the very being of the atom if it is otherwise hard to observe. Assorted devices have been developed for observing radiation. These devices are used for a assortment of intents, including medical diagnosings, radioactive dating measuring, mensurating back land radiation, and mensurating the mass, energy, and impulse of atoms is created in high-energy atomic reaction.Consequence OF RADIATION ON HUMANSA really little sum of ionising radiation could trip malignant neoplastic disease in the long term even though it may take decennaries for the malignant neoplastic disease to look. Ionizing radiation ( x-rays, radon gas, radioactive stuff ) can do leukaemia and thyroid malignant neop lastic disease. There is no uncertainty that radiation can do malignant neoplastic disease, but there still is a inquiry of what degree of radiation it takes to do malignant neoplastic disease. Quickly spliting cells are more susceptible to radiation harm. Examples of radiosensitive cells are blood organizing cells ( bone marrow ) , enteric liner, hair follicles and foetuss. Hence, these develop malignant neoplastic disease foremost. If a individual is exposed to radiation, particularly high dosage, there are predictable alterations in our organic structure that can be measured. The figure of blood cells, the frequence of chromosome aberrances in the blood cells and the sum of radioactive stuff in piss, are illustrations of biomarkers that can bespeak if one is exposured high dosage. If you do non hold early biological alterations indicated by these measurings the radiation exposure will non present an immediate menace to you.Radiation toxic conditionRadiation toxic condition, radiation illness or a crawl dosage, is a signifier of harm to organ tissue caused by inordinate exposure to ionising radiation. The term is by and large used to mention to acute jobs caused by a big dose of radiation in a short period, though this besides has occurred with long term exposure. The clinical name for radiation illness is acute radiation syndrome as described by the CDC A chronic radiation syndrome does be but is really uncomm on ; this has been observed among workers in early Ra beginning production sites and in the early yearss of the Soviet atomic plan. A short exposure can ensue in acute radiation syndrome ; chronic radiation syndrome requires a drawn-out high degree of exposure. Radiation exposure can besides increase the chance of developing some other diseases, chiefly malignant neoplastic disease tumours, and familial harm. These are referred to as the stochastic effects of radiation, and are non included in the term radiation.Radiation ExposureRadiation is energy that travels in the signifier of moving ridges or high-velocity atoms. It occurs of course in sunshine and sound moving ridges. Man-made radiation is used in X-rays atomic arms, atomic power workss and malignant neoplastic disease intervention. If you are exposed to little sums of radiation over a long clip, it raises your hazard of malignant neoplastic disease. It can besides do mutants in your cistrons, which you could go through on to any kids you have after the exposure. A batch of radiation over a short period, such as from a radiation exigency can do Burnss or radiation illness. Symptoms of radiation illness include sickness, failing, hair loss, skin Burnss and decreased organ map. If the exposure is big plenty, it can do premature aging or even decease.
