Do Voilent Video Games Cause Violence in Children?

Carolina Hernandez Do Violent Video Games Cause Violence In Children? 1. Introduction A. Attention Catcher: Imagine you’re in your room, all the lights are off, and you TV is on, you sit there holding a game controller, the words GAME OVER are flashing on the screen. The game was hard, you killed as many zombies as you could, and this is what you get?! A game over screen?! You play the level again. Mid-way through the level, someone opens the door to your room.The light stings your eyes, momentarily forgetting about the game, your character dies because a zombie ate his brains. You get so angry; you punch the person who made you lose the game! B. Listener Relevance Link: Most of you in this room play video games, right? Do you ever feel†¦angry after playing a violent video game? If you’re one of the people who don’t, it’s mostly because of your personality. If you’re an angrier person by nature, these video games should affect you more if you a re. C. Speaker Credibility Statement:Let me start this off by saying I love video games. I have a video game in my backpack right now. Most of the video games I play are adventure games that involve fighting. Usually I’m not affected by them, unless I get competitive about it. My brother and I used to fight after playing a game if one of us lost, and sometimes it would result in fist fighting. My brother and I don’t play video games together that much anymore. Still, after playing a particularly violent game, I will not be angry, but my brother will.This is because we’re different types of people with different personalities, which results in different reactions. Video games never made me want to kill someone. D. Thesis Statement: All this results in one questions, do violent video games affect the player’s violent tendencies? E. Preview: In this speech, I’ll talk about the research done on this topic, and it’s results on how it affects chil dren and teen’s violent tendencies. 2. Body A. First Main Point These days, video games about violence are the most popular types of games.The rating system the games are put through should be the answer, but when states have tried to keep underage children from playing â€Å"M† games, they are often challenged in court in favor of the said child who wants to play the game. Though video games DO cause violence, they are over-dramatized to how MUCH violence they cause. In one of my sources, the mild-manner personality types were least affected, while angry people by nature where affected more. 1. Sub Point Professor Patrick Markey Says â€Å"Their personality made a big difference.People who are extremely angry tend to be much more affected by violent videogames than people who are not angry and of course the opposite is true that people who are not angry are virtually unaffected by violent videogames. So it’s both the person and, in essence, the situation. â₠¬  B. Second Main Point In 2003, teenager Devin Moore shot and killed 3 people in a police station in Alabama. After being found and caught by the police, Moore told them in a police interview â€Å"Life is like a video game. Everybody’s got to die sometime. This resulted in a lawsuit against the advertisers of Grand Theft Auto, the game that two of the families of the victims claimed compelled him to do what he did. (The game is like a simulated cop-killer. ) 1. Sub Point What I just told you was an extreme case of violent video games gone wrong. Most of the people who do play Grand Theft Auto play it for fun. Nicholas Hammer, a law student at the time who was demonstrating the video game for the source, says he, like every other person who plays violent video games, plays them for fun.But did you ever think that the reason a person did this was not just the video game, but the person itself and their environment? 2. Sub Point Moore was compelled to do what he did is based on his environment. Moore came from a troubled home and bounced from foster family to foster family. When you are a teenager, the part of your brain that manages things like impulse control and urges, is under development during teen years, not fully developed until our early twenties.David Walsh, a Children’s psychologist says â€Å"†¦ when a young man with a developing brain, already angry, spends hours and hours and hours rehearsing violent acts, and then, and he's put in this situation of emotional stress, there's a likelihood that he will literally go to that familiar pattern that's been wired repeatedly, perhaps thousands and thousands of times,† So it was not really the video game in this scenario, but the type of person and their respective environments.C. Third Main Point Many states have tried to ban sales of rated â€Å"M† video games to those under 17; Minnesota even tried to make a law that would fine children caught with â€Å"M† video games that was unsuccessful. I believe that there should be certain laws made against minors buying â€Å"M† video games. 1. Sub Point I believe that there should be a law that prohibits minors from buying rated â€Å"M† games unless there is a parent or guardian there with them.This would make it harder for children to buy video games that are â€Å"M† because their parents would most likely not approve of them. 2. Sub Point Demos of the video game should be offered to parents for the parent to play before buying it for their child. If a parent is offered a demo, they are more likely to play it to see if they want their child to be playing this before they give them the actual game. 3. Sub PointVideo game stores should have a mandatory ID or Driver’s License check when a minor is buying a rated â€Å"M† video game. 3. Conclusion A. Thesis Restatement Video games don’t really have a large part in violent tendencies, but it still depends on the type of person or their environment. But there should still be laws not allowing minors to buy rated â€Å"M† games. B. Main Point Summary These main points are all about how video games, and how to stop minors from buying rated â€Å"M† games. C. ClincherWhether or not, in the end, video games have a large affect on a certain type of person’s mindset, something should be done to stop minors from playing games that are inappropriate for their age. 4.

The arguments put forth by Camille Pecastaing

The arguments put forth by Camille Pecastaing, in her article named â€Å"A Brief History of the Next War,† are mainly based on the international system. While analyzing the book ‘Iran, The Choice of Arms?’ an international security analysis by Franà §ois Heisbourg, she exposes the major chinks in the author’s arguments. She draws a clear distinction between fact and speculation.Franà §ois Heisbourg, in his theory which is in fact speculation interlaced with facts, argues that a nuclear Iran will be the most serious threat to the world peace. Camille Pecastaing has rightly called his bluff when she points out that such a scenario simply does not exist.Instead she emphasizes on the unforeseen economical fallout on the world economy in the wake of any unilateral strike by the US. Iran’s capability to block the straits of Hormuz is real and if the tactics employed by Iran in the Afghanistan and Iraq are any indication, the strike will only damage Amer ica’s own economy and the international standing than that of Iran. So she stresses that it is in America’s interest not to think of such a misadventure.The arguments of Camille Pecastaing in this article reflect a realist thought process. It examines the international security scenario analysis and possible remedial actions proposed by another author who takes inferences from the actions and imaginary intentions of certain countries.Ambition of Iran to acquire nuclear deterrent is seen by the West as a threat to world peace, fearing regional proliferation and irresponsible posturing. But she sees no imminent danger to the world peace by the actions of Iran and on the contrary, as she understands it, will lead only to a more mature behavior on the part of Iran and Israel as in the case of India and Pakistan.The question of proliferation does not arise as the neighboring countries are too dependent on US military know how and support that they cannot think of acquiring a nuclear weapon.I am in complete agreement with the arguments of Camille Pecastaing. In order to prove Heisbourg’s arguments wrong in saying that the Iranian bomb is ‘apocalyptic’, and it needs to be stopped at any cost, she depicts the futility of strike without a ground invasion, the prospect of failure similar to the one America now faces in Iraq and Afghanistan, the possible negative fallout on America’s already troubled economy and the weakening clout of the dollar. Iran is in a position to cause more damage to the world economy in general and the US economy in specific than the damage the US action can cause to the Iranian economy.The argument of Heisbourg that Iran will slip into anarchy and the nuclear arsenal will fall into the hands of Hezbollahis is only a wishful thinking. As she rightly points out, in all probability, an Iranian nuclear weapon will make both Iran and the nuclear Israel more responsible and the chances of further confrontation s between these two countries and the related chaos that may ensue, will only decline.It is evident from the above paragraph that I am in complete agreement with Camille Pecastaing and it is needless to say that my opinions belong to the realist school of thoughts. To further my arguments in that favor, I can point out some of the past events that led to the invasion of Iraq.American intelligence and spy agencies had manufactured false evidences to strengthen their claim that Iraq is in the process of building weapons of mass destruction which will threaten the world peace and this was believed by the other countries without any doubt who in turn lend their support for an American invasion.Later, when it was found out that it was only a fear psychosis created by the US, it was too late to rectify the damage and the difficulties it caused in Iraq. Moreover, the monumental expenditure for the Iraq war has only put the US economy in undue trouble.

Free Trade Zones in UAE and Economic Development Research Paper - 1

Free Trade Zones in UAE and Economic Development - Research Paper Example In a free trade zone, all the imports are free from duties and all the exports from this region are free from restrictions but only when those goods reach to other destinations, they become subject to the local custom rules. Ireland was the first country to come up with this idea and the main purpose was to industrialize the rural areas of the country and attract foreign investment to induce the economy and provide better employment to the locals (Davidson, 2008). United States, China, Brazil, Indonesia, India, Malaysia, Philippines and many other countries have various free trade zones, all for the same purpose (Krane, 2009). United Arab Emirates is the recent addition to the list of the countries, which are looking for aggressive economic growth and one of the approaches taken for the same is setting up various free trade zones in order to encourage foreign direct investment (Oxford Business Group, 2010). The country has over 20 free trade zones and the paper is an attempt to shed some light on the free trade zones of Dubai Media City and Abu Dhabi Airport (Barrett, 2010). The paper will discuss their positive and negative contributions to the economy of UAE, benefits to investors and strategies for growth. Furthermore, the paper will also shed some light on the differences between employment rules in the free trade zones and other areas of the country. Discussion Dubai Media City It was in the year 2001 when the Dubai government launched Dubai Media City as a free trade zone that has now become the regional hub of media companies in the Middle Eastern regions. Reputable media companies such as CNN, BBC, GEO Tv, ARY Digital, Bloomberg, Cartoon Network, CCTV Orbit Showtime, CNBC and others have set up their regional headquarters and broadcasting centers in the city. Furthermore, Financial Times, The Sunday times, The Economist and other well known print media companies have their regional centers in the Dubai Media City. McGraw Hill, Forbes, ITP Publishing Gro up and other leading players in the publishing are also located in the city. On top of these, the city takes great pride in the fact that headquarters of the ICC (international Cricket Council, the supreme governing body of cricket worldwide) is located in Dubai Media City. Over 1400 companies are registered and operating in the Dubai Media city (Krane, 2009). Over the past decade of its existence, the Dubai Media City has been instrumental in boosting the economic growth of the country. Furthermore, not only it has helped to provide employment to the local people however as of today, Dubai Media City is the home to thousands of people skilled, trained, experienced and learned in media related jobs. Many foreign students come to Dubai for their media studies considering the exposure that they could get from Dubai Media City. Foreign Direct Investment has kept on increasing and the tourism and hospitality industry has received great deal of business (Kanna, 2011). The downside of all this economic growth is the fact that this economic growth cannot be termed as sustainable or long-term growth. Despite the fact that the GDP of the region and the country has increased greatly due to the presence of huge media companies, however, these companies have ended up with employing a significant majority of expatriates, non-locals and non-Emiratis (Oxford Business Group, 2010). These percentages range from 80 percent to 99 percent. The point

Final - Essay Example The North/South conflict in The Octoroon elaborated on the consequence of the secession of southern states, particularly Louisiana, from the United States. It gave rise to the prohibition from marriage of Whites and Octoroons or those which bears 1/8 black heritage. The segregation between Whites and those with black heritage were presented so critical in the play. In Shenandoah, marriage or romantic relationship was not emphasized. The North/South conflict was introduced as it is. Conflict of interest due to the regional associations of the character which complicated issues relating to personal engagements. In the latter, the political facet of the North/South conflict was stressed. [Student’s Last Name] 2 2. From the late 19th century to early 20th century, there were significant changes in the entertainment as a business. What were those changes and how do they reflect what we see in the entertainment today? In the later part of the 19th century, the United States develope d home entertainment, theatrical shows and folk music and dances as observed and eventually copied from different countries like Ireland, Canada and Germany. The entertainment industry in the United States focused more on consolidating different types of culture into one state aiming for a centralized entertainment that would attract more audience around the globe. Immigration surged and many foreign artist were recruited for different theatrical and musical productions which contributed a lot to the entertainment industry of the US. In 1880, years after the Civil War and the widespread emancipation of Blacks, a great variety of performers and artists flocked into one. As we can see today, Blacks are given equal opportunity. Also, more and more foreign artists are immigrating to the US to pursue career in music. 3. How were the immigrant/ethnic acts in vaudeville different from the other entertainments we’ve studied that featured people who were different from the â€Å"norm al† citizen? In principle, foreign citizens or immigrants or both essentially had their individual upbringing. Since they have grown up with the kind of culture which is customary and prevalent in their mother nations, it would most likely be reflected on their entertainment style, whether it is in music, dance, comedy, magic or any other type of artistic skill. [Student’s Last Name] 3 In 1880, years after the American Civil War, the United States started to embrace variety in entertainment. There was a mixture in the entertainment industry with different races and colour transpired into the performances of many immigrant performers. The acts in vaudeville of immigrants differ from the normal citizen largely because of cultural variations and customary influence which until now is still apparent just like musicals which play in Broadway that depict some of the old English love stories and events. PART II 1. Compare the character of the American people as it is exhibited in The Octoroon with the character as seen through Buffalo Bill’s Wild West. What changed and what remained the same? How do they compare with our attitudes about similar issues today? More than just the recurring scenes featuring cowboys, shooting and horses, Buffalo Bill’s Wild West highlighted the kind of life there was in the west or the so-called

Questions about Gender and Generation Management in the workplace Essay

Questions about Gender and Generation Management in the workplace - Essay Example the organisations achievement of objectives (Bagilhole & White, 2013) It helps in coordinating the various generations in the workplace because all their opinions matter and everyone’s input is valued and incorporated in the firm’s means of achieving the objectives. 2. I would prefer working with generation X due to the fact that it’s a generation made of young people who can make quick decisions and have innovative minds. Their fast decision making tendencies helps in moving the firm forward and achieving the set objectives which increases the value of the firm. Also, the innovative minds helps in coming up with new ways of doing things and processes gives the firm a competitive edge against competitors. 3. Generation Y would be most challenging to manage and lead due to the fact that it is made up of quite older people who are a bit resistant to change. Most of them get stuck with rules and procedures set earlier, and are not willing to change. This makes incorporating valuable changes in an organization difficult; and of course this means that the firm cannot move forward as fast as expected or as planned. 4. The average age for retiring from work is 60. Some of primary reasons as to why people should retire are; it is a state requirement for civil servants to retire, they are no longer as productive as before and also to concentrate on something else they had wished to do. The reasons are individual and others come from external forces like the state requirement for civil servants to retire in order to give way for other qualified citizens to get the chances to work. 5. Generation X is impatient and at the same time dismissive. Most children born during this era display a lot of impatience in most things they undertake in their day to day activities, including undertakings at school, work and even at home. They also dismiss most of the ideas offered by other people mostly the older generation including their parents and other older siblings. On the

Health Promotion Teaching Plan - Research Paper Example at the rules stipulated in the memo can be reviewed and a thorough checking be conducted in order to ensure that the students have obeyed them to the letter. The historical exercise of â€Å"hands on† teaching in healthcare professions, whereby students learn through practice on real stress reduction strategies, diet and exercise under supervision, may not be justifiable as the principal model for preparing healthcare experts. This challenge could be aggravated by the advance of directed health plans; patients paying for their own healthcare may refuse to serve as â€Å"teaching material,† the price traditionally paid for receiving care at a teaching hospital or public clinic. Consequently, real people with wellness problems are needed to avoid of caregivers shortages under such situations ( Riley, 2008). The instructor will listen to how the other nursing students respond to a given incident and provide guidance where needed. The observational notes will be look over during the next class with all students. Nursing students learn in two ways, through text books, and by being in a hospital environment, which allows them to familiarize themselves with real life situations; as such, the lesson provide a way for the students to practice in an environment that is comparable to a real life situation. This will better prepare the students for their upcoming healthcare nursing studies (Loyd, Lake, & Greenberg, 2004). The main challenge faced by nursing students is that they are not familiar with carrying out proper procedures during circumstances that are covered in their textbooks, and it is for that reason that nursing students need to be able to have a way to practically apply the proper procedures of the medical field’s practices, especially in health and wellbeing. The practice of using role-playing scenarios at random throughout a course of study considerably helped students to be prepared to act on any situation as if they were in a real situation ( Sanchez,

Critical analysis worksheet Essay Example | Topics and Well Written Essays - 1000 words

Critical analysis worksheet - Essay Example Low nutrition expensive food is in the market not because of farmers’ equipment prices have soared, the consolidation is the real evil behind it. When someone walks into a shop, they see a huge number of brands selling different food products. This might seem like a good thing as more players enter in a market, competition increases and hence the quality and price remain under control. However the reality is far from it, those thousands of brands represent only a handful of companies, their parent companies, their real owners. There is one major distributor of organic food in the country and United National Food Inc. (UNFI) and Whole Foods are its major customers (Breaking up the Foodopoly, 2013). Companies use food science to make people addicted to the processed food – fat, sugar and salt are put in perfect combination so that the brain reaches nirvana, and releases dopamine; the brain sets up a neuro-circuit of eating food as a reward. Consolidated companies and food quality boards control everything, even the nutrition requirements, politicians are involved in it too, but there is still hope as things are improving. While such news would not get spotlight on mainstream media channels but with the boom of social media people can talk and create awareness. Along with voting with fork, people also need to vote for better politicians that are interested in people’s health rather than corporate profits. 2. What questions would you ask the author (at least 2 questions) The two questions I would ask the author would be; 1) How can average American (or anyone in the world) create active awareness regarding foodopoly? What do you suggest people should do other than updating statuses on social media websites and liking news articles such as yours? 2) What can be done to develop a board or a committee that can keep an eye on the standard of food and food prices? The companies involved in this business are very strong and they can hire lawyers that can win them any case, so how do we fight on this platform that we need an independent board (independent of politics and corporate influence) that would make decisions about food pricing and quality solely on scientific and economic reasoning? 3. Do you agree with the main premise of the reading? Why or why not? What evidence or personal experience would you offer to? I completely agree with the premise of the article, there is consolidation; there is food-monopoly (foodopoly). One doesn’t need to be an expert to realize what is going on in the food market. A little search on the internet reveals the massive scale on which consolidation is being done in the food market. Corporates controlling food industry is devastating, people can’t avoid food, and it’s not a luxury. People get hungry and they need to eat. So controlling (or consolidating) the market means one controls people’s hunger and their wants and needs. Corporates can put up a television comme rcial showing a doctor telling the public how important it is to have an egg in the breakfast and some cereals and wash it down with milk. Everyone knows it’s just a commercial to sell milk, cereals and eggs, but the subconscious takes it all in, the brand name too. So when it comes to

Technology - Essay Example For a school setup, the preeminent suggested computer placement arrangement entails the use of laboratories. In this setup, the placement of the machines should be done in the two 30-station computer labs. This method is suitable in this particular setting since the student’s improvement in learning computers can be closely scrutinized. Moreover, the vulnerability of destruction of the machines will be significantly reduced. In addition, the computer teachers are able to monitor the computers in order to avoid cases connected to theft of computers and the peripheral devices. According to the lab station method, the computers are arranged in the room in an organized manner to prevent learners and other individuals from stumbling over the peripheral devices. In the arrangement of computers, in a lab, there are three main arrangement setups. They include computers arranged in clusters of four, horse shoe facing the walls and rows of computers facing the front board (Andrew, 2010). Experts prefer the use of the horse shoe organization method. This is because the lecturer is able to move around the lab pretty effortlessly in case any novice needs aid on something (Andrew, 2010). In the horseshoe setting, the wiring method will be from the mains circuit to the feeder wires that will transmit power to the computers in the lab. In terms of security, the school should install an alarm system for the two lab rooms, and also introduce strict rules that will protect the computers from damage by the learners. Also, the arrangement setup should also consider that the lab is well aerated to prevent the machines from overheating. This will improve the effectiveness and performance of the computers (Tison, 1991). On the one hand, the school board should pick apt and learned individuals who will be responsible for maintaining the computers and the computer labs. The selection made

Demand Curve and Supply Curve Essay Example for Free

Demand Curve and Supply Curve Essay Demand and supply have been generalized to explain macroeconomic variables in a market economy. The Aggregate Demand-Aggregate Supply model is the most direct application of supply and demand to macroeconomics. Compared to microeconomic uses of demand and supply, different theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. The AD-AS or Aggregate Demand-Aggregate Supply model is a macroeconomic model that explains price level and output through the relationship of aggregate demand and aggregate supply. It is based on the theory of John Maynard Keynes presented in his work â€Å"The General Theory of Employment, Interest, and Money†. It is one of the primary simplified representations in the modern field of macroeconomics and is used by a broad array of economists, from libertarian, monetarist supporters of laissez-faire, such as Milton Friedman to Post-Keynesian supporters of economic interventionism, such as Joan Robinson. Brief history of demand curve and supply curve According to Hamid S.  Hosseini, the power of supply and demand was understood to some extent by several early Muslim economists, such as Ibn Taymiyyah who illustrates- â€Å"If desire for goods increases while its availability decreases, its price rises. On the other hand, if availability of the good increases and the desire for it decreases, the price comes down†. In 1691, John Locke worked on some considerations of the consequences of the lowering of interest and the raising of the value of money. It includes an early and clear description of supply and demand and their relationship. In this description demand is rent: â€Å"The price of any commodity rises or falls by the proportion of the number of buyer and sellers† and â€Å"that which regulates the price of goods is nothing else but their quantity in proportion to their rent. † The phrase supply and demand was first used by James Denham-Steuart in his Inquiry into the â€Å"Principles of Political Oeconomy† which was published in 1767. Adam Smith used the phrase in his book â€Å"The Wealth of Nations† (1776) and David Ricardo titled one chapter of his work â€Å"Principles of Political Economy and Taxation† (1817) On the Influence of Demand and Supply on Price. In The Wealth of Nations, Smith generally assumed that the supply price was fixed but that its value would decrease as its scarcity increased, in effect what was later called the law of demand also. Ricardo, in Principles of Political Economy and Taxation, more rigorously laid down the idea of the assumptions that were used to build his ideas of supply and demand. Antoine Augustin Cournot first developed a mathematical model of supply and demand in his 1838 Researches into the Mathematical Principles of Wealth including diagrams. In1870, Fleeming Jenkin in the course of Introducing the diagrammatic method into the English economic literature published the first drawing of supply and demand curves including comparative statics from a shift of supply or demand and application to the labor market. The model was further developed and popularized by Alfred Marshall in the textbook â€Å"Principles of Economics† (1890). The Standard demand curve and the aggregate demand curve The standard demand curve represents the quantity of a good that a consumer will buy at a given price, holding all else constant. For example, consumer A might buy zero oranges at $1 each, one orange at 75 cents each, and two at 50 cents each, while consumer B might buy one at $1, two at 75 cents, and three at 50 cents. When charted on a grid with price on the vertical axis and quantity purchased on the horizontal axis, these points form the individual demand curves for consumers A and B. The aggregate demand curve represents the total quantity of all goods (and services) demanded by the economy at different price levels. An example of an aggregate demand curve is given in Figure 1. The vertical axis represents the price level of all final goods and services. The aggregate price level is measured by either the GDP deflator or the CPI. The horizontal axis represents the real quantity of all goods and services purchased as measured by the level of real GDP. Notice that the aggregate demand curve, AD, like the demand curves for individual goods, is downward sloping, implying that there is an inverse relationship between the price level and the quantity demanded of real GDP. The standard supply curve and the aggregate supply curve The standard supply curve is a graph showing the relationships between the price of a good and the quantity supplied. The supply curve slopes upward because other things equal, a higher price means a greater quantity supplied. The aggregate supply curve shows the relationship between the price level and the quantity of goods and services supplied in an economy. The equation for the upward sloping aggregate supply curve, in the short run, is Y = Ynatural + a (P Pexpected). In this equation, Y is output, Ynatural is the natural rate of output that exists when all productive factors are used at their normal rates, â€Å"a† is a constant greater than zero, P is the price level, and Pexpected is the expected price level. This equation holds only in the short run because in the long run the aggregate supply curve is a vertical line, as output is dictated by the factors of production alone. An aggregate supply curve is shown in Figure 2. The aggregate supply curve equation means that output deviates from the natural rate of output when the price level deviates from the expected price level. The constant, a, shows how much output changes due to unexpected deviation in the price level. The slope of the aggregate supply curve is (1/a) which depicts the short-run aggregate supply curve and the long- run aggregate supply curve. The vertical axis is the price level. The horizontal axis is output or income. The short-run aggregate supply curve is downward sloping with slope equal to (1/a) while the long-run aggregate supply curve is vertical with no slope. The reason that the short-term aggregate supply curve is upward sloping is a bit more complex. Factors that determine the slope of AD-AS curve model The slope of AD curve reflects the extent to which the real balances change the equilibrium level of spending, taking both assets and goods markets into consideration. An increase in real balances will lead to a larger increase in equilibrium income and spending, the smaller the interest responsiveness of money demand and the higher the interest responsiveness of investment demand. An increase in real balances leads to a larger level of income and spending, the larger the value of multiplier and the smaller the income response of money demand. This implies that the AD curve is flatter, smaller is the interest responsiveness of the demand for money and larger is the interest responsiveness of investment demand. Also, the AD curve is flatter; the larger is the multiplier and the smaller the income responsiveness of the demand for money. We know that aggregate demand is comprised of C(Y T) + I(r) + G + NX(e) = Y. Thus, a decrease in any one of these terms will lead to a shift in the aggregate demand curve to the left. The first term that will lead to a shift in the aggregate demand curve is C(Y T). This term states that consumption is a function of disposable income. If disposable income decreases, consumption will also decrease. There are many ways that consumption can decrease. An increase in taxes would have this effect. Similarly, a decrease in incomeholding taxes stablewould also have this effect. Finally, a decrease in the marginal propensity to consume or an increase in the savings rate would also decrease consumption. The second term that will lead to a shift in the aggregate demand curve is I(r). This term states that investment is a function of the interest rate. If the interest rate increases, investment falls as the cost of investment rises. There are a number of ways that investment can fall. If the interest rate rises, say due to contractionary monetary or fiscal policy, investment will fall. Similarly, in the short run, expansionary fiscal policy will also cause investment to fall as crowding out occurs. Another interesting cause of a fall in investment is an exogenous decrease in investment spending. This occurs when firms simply decide to invest less without regard for the interest rate. The term variable that will lead to a shift in the aggregate demand curve is G. This term captures the whole of government spending. The only way that government spending is changed is through fiscal policy. Recall that the budgetary debate is an ongoing political battlefield. Thus, government spending tends to change regularly. When government spending decreases, regardless of tax policy, aggregate demand decrease, thus shifting to the left. The fourth term that will lead to a shift in the aggregate demand curve is NX(e). This term means that net exports, defined as exports less imports, is a function of the real exchange rate. As the real exchange rate rises, the dollar becomes stronger, causing imports to rise and exports to fall. Thus, policies that raise the real exchange rate though the interest rate will cause net exports to fall and the aggregate demand curve to shift left. Again, an exogenous decrease in the demand for exported goods or an exogenous increase in the demand for imported goods will also cause the aggregate demand curve to shift left as net exports fall. An example of this type of exogenous shift would be a change in tastes or preferences. The aggregate demand curve also can shift right as the economy expands. When the aggregate demand curve shifts right, the quantity of output demanded for a given price level rises. Therefore, a shift of the aggregate demand curve to the right represents an economic expansion. A shift of the aggregate demand curve to the right is simply affected by the opposite conditions that cause it to shift to the left. A change in one or more of the following determinants of aggregate supply will shift the aggregate supply curve in the short run. Change in the input prices (domestic or imported resources price), change in productivity, change in legal institutional environment (business taxes and government regulation). An increase in short-run aggregate supply will shift the curve rightward; a decrease will shift the curve leftward. The long run aggregate supply curve is vertical. Similarities between the Ad-AS curve model and the standard demand-supply curve model The conventional aggregate supply and demand model is actually a Keynesian visualization that has come to be a widely accepted image of the theory. The Classical supply and demand model, which is largely based on Says Law, or that supply creates its own demand depicts the aggregate supply curve as being vertical at all times. The both demand curve and the aggregate demand curve is negatively sloped from left to right and both curves represent the law of demand. The short-run aggregate supply curve or SRAS curve has similarities the standard supply curve. Both are positively sloped. Both curves relate price and quantity. Differences between the Ad-AS curve model and the standard demand-supply curve model In aggregate demand curve, there is no substitute effect because we cannot substitute all goods. But in standard demand curve it exists. The aggregate demand curve has no income effect because a lower price level actually means less nominal income for the resource suppliers’ e. g. lower wages, rents, interests, and profits. But in standard demand curve it exists. The major differences between the standard supply curve and the aggregate supply curve are as follows- for the market supply curve, the vertical axis measures supply price and the horizontal axis measures quantity supplied. For the short-run aggregate supply curve, however, the vertical axis measures the price level (GDP price deflator) and the horizontal axis measures real production (real GDP). The positive slope of the market curve reflects the law of supply and is attributable to the law of diminishing marginal returns. In contrast, the positive slope of the short-run aggregate supply curve is attributable to: (1) inflexible resource prices that often makes it easier to reduce aggregate real production and resource employment when the price level falls, (2) the pool of natural unemployment, consisting of frictional and structural unemployment, that can be used temporarily to increase aggregate real production when the price level rises and (3) imbalances in the purchasing power of resource prices that can temporarily entice resource owners to produce more or less aggregate real production than they would at full employment. Conclusion Whereas the standard supply and demand curve model discusses on individuals, the aggregate supply and demand curve model works with the whole economy. This model is built on the assumption that prices are sticky in the short run and flexible in the long run. This model also highlights the role of monetary policy. This model shows how shocks to the economy cause output to deviate temporarily from the level implied by the standard model. By this model, we can observe the economy more efficiently than before.

God bless Essay The novel WICKED WITCH OF THE WEST by Gregory Maguire focuses upon an evil soul of a witch, the dialog, One never learns how the witch became wicked, or whether that was the right choice for heris it ever the right choice? p. 231 explains how the wickedness of the witch cannot be truly explained or her personality assessed by the writer, it is up to the reader to decide on a conclusion regarding the motivations behind it. The four travellers Dorothy, Scarecrow Nick Chopper, Cowardly Lion’s discussion of the rumours about the witch while she herself listens to their talk decides to confront Dorothy next time. The writer also writes in detail about the birth of the witch as well as her family background, relating religion with the evil characters. Its people who claim that theyre good or anyway better than the rest of us, that you have to be wary of. (Maguire p. 357). The readers are being warned about the different natures of the characters in the end the domination of good against evil by stating, In the life of a Witch, there is no after, in the ever after of a Witch there is no happily; in the story of a Witch, there is no afterward. (Maguire P. 406) Thesis: In this society when we encounter evil, it is not only due to person’s own act but whole of the society is involved in the evil act. Every person has something good and bad in his character but sometimes society creates circumstances that a person is forced to become evil. Body 1 [Plot] This story begins with the birth of Elphaba the daughter of Frex and Melena, Melena was alone at the time when she give birth to Elphaba, as despite of being with his wife at the birth of their first child Frex had traveled to preach, specifically, the Clock of the Time Dragon. Melena give the birth to the daughter with green skin color which was very odd, for many years they hide this secret but when Elphaba grown up she was sent to the schools and college. Galinda was Elphaba first roommate but Galinda always ignore her, later on they become friends Galinda was working with Dr Dillamond, he was killed in this story from this point the sad part starts, Elphaba blame Madame Morrible and her robot-like assistant, Grommeti. But later on Fiyero comes into Elphaba life’s’ he, as she was alone they both had the affair but after few time he consider that Elphaba has murdered Madame Morrible, Fiyero was as well killed, and later on she was known as the witch of town as she did not fights against rumors about her and at last she died because of bucket of water which was throw on her to save her from fire. â€Å"The funeral was modest, a love-her-and-shove-her affair† (Maguire, p 154) The main character of this novel is Elphaba, an individual who was born with distinct features personality. The appearance is mocked by others living around her, A green child will be an open invitation for scorn and abuse. (Maguire P. 48). The interesting feature is the transformation of this person from a naive girl to the one seeking revenge thus attains the nickname WICKED WITCH OF THE WEST thanks to her malevolence. However this is justified by the extreme love the suffering in result she feels for her family friends. Another character Dorothy a young innocent girl, along with her escorts Scarecrow, Nick Chopper, Cowardly Lion is the opponent of the witch, but loved by the other people. She is also responsible for the witch’s death in the end of the novel.

DNA Transformation in Bacteria

DNA Transformation in Bacteria 1.0 Introduction and Objectives The ability of bacteria to incorporate DNA from external sources is the primary reason for their survival and proliferation. Bacteria can take DNA from their surroundings or from other bacterial cells by cell wall-transfer. While an interesting phenomenon to examine for scientists, practically it is of great concern for the human race and a source of constant challenge for the Pharmaceutical Industry. The ability of bacteria to modify their genetic information has given rise to problems such as antibiotic resistance wherein bacteria become resistant to medications that were once effective in eliminating them. In this experiment, we examine the development of antibiotic resistance in bacteria. Circular DNA called plasmids are introduced in bacteria whose cells have been modified to promote uptake of plasmid DNA. This plasmid DNA will give rise to antibiotic resistance in the bacteria, which can be observed by allowing the bacteria to proliferate in an environment containing the antibi otic. Modification of genetic information in bacteria may be a source of concern, but that ability in the hands of humans has always been coveted. Genetic engineering is an increasingly popular research area given the breakthroughs made in recent years and the potential for commercial application. Various applications require large quantities of specific DNA sequences and this is where the bacterial ability to uptake DNA and reproduce it is beneficial. Introducing plasmids containing desired sequences into bacteria, allowing bacteria to reproduce and then isolating the required DNA is a common method used to obtain large quantities of particular DNA sequences. This aspect is also explored in this experiment. 1.1 Objectives The objectives of this experiment are to: a) Observe and examine the phenomenon of DNA Transformation. b) Observe the development of antibiotic resistance in bacteria through the process of gene transformation. c) Inculcate proper Sterile Technique for laboratory procedures involving bacterial strains. 2.0 Principles This section explores the underlying concept behind the experiment. Genetic Transformation is a process of horizontal gene transfer whereby DNA from the environment is taken up by a host cell. In this experiment bacterial cells are transformed. Escherichia Coli bacteria, which are generally non pathogenic are used in this experiment. The plasmids which constitute the external DNA contain a gene that makes the cell ampicillin resistant. Ampicillin is a bacteriostatic and will normally prevent the reproduction of E. Coli bacteria. This provides us with an easy way to test if gene transformation has occurred and to what extent by means of calculating the transformation efficiency. The introduction of genetic material within the bacterial cell is done by the process of electroporation. Electroporation involves applying an electrical voltage across the bacterial cells containing the plasmids. The ionic concentration of the DNA is kept low to prevent arcing. When the voltage is applied, holes open up in the walls of the bacteria. The plasmids can then enter the bacterial cells through these holes. Application of the voltage is done for a very short period of time. As soon as electric current stops flowing, the holes in the cell wall begin to close. A nutrient rich medium is then added to the bacterial cells, some of which will have transformed, to aid cell recovery. Incubation is then carried out, after which the cell suspension is diluted further and applied to agar plates containing the antibiotic. The cells are left to incubate for up to 24 hours and then the number of colonies determined. Calculating the transformation efficiency gives us a method to determine the extent to which the transformation occurred. 3.0 Methods and Materials 3.1 Materials The equipment and materials required for this experiment are outlined in this section. Equipment Required: A shaking incubator operating at 37ÃÅ'Ã…  C A non-shaking incubator An electroporator Materials Required: Cells treated for competency 2 agar plates with ampicillin with a concentration of 100 Â µg/ml pUC-19 plasmids 0.1 cm cuvettes Ice in an ice-box Deionised ultrapure water S.O.C. medium at room temperature 2 tubes with snap caps with a volume of 15 ml 3.2 Sterile Technique Sterile Technique is a must when handling pathogenic strains of bacteria. In this experiment, nonpathogenic bacterial strains are employed. However, using sterile technique is still good experimental procedure and promotes safety. Using sterile technique prevents errors in experimental results by preventing contamination from the surroundings. It also prevents contamination of the surrounding environment by the bacterial strain. Steps employed to prevent contamination included: Carrying out the experiment in an uncluttered area. Utilizing a fume hood to perform all procedures involving the bacteria. Washing hands both before as well as after the experiment Disposing off all bacterial waste in the appropriate container for bio-hazardous materials. 3.3 Procedure 3.3.1 Preparation for Electroporation The 0.1 cm cuvettes were cooled on ice. The electroporator was prepared based on prescribed settings. In order to bring the S.O.C. medium to room temperature, it was removed from the ice box. The cells and plasmids were allowed to thaw in the ice-box. Plates were heated at 37ÃÅ'Ã…  C to prepare for the incubation process. 3.3.2 Procedures I Â µl of pUC19 control DNA and 1 Â µl of ultrapure water were added to 2 separate microcentrifuge tubes with the aid of a pipette. The tube was then placed in the ice-box. 25 Â µl of competent cells were added to each of the microcentrifuge tubes. The contents of the tubes were gently mixed. Care was taken to avoid usage of the pipette for mixing. The tubes were then returned to the ice-box for 1 minute. The contents of each microcentrifuge tube were transferred to a cuvette using a pipette. It was ensured that the cells made contact with the cuvette walls and that no air-bubbles were present. This step was done rapidly to prevent heating up of the cells. The cuvettes were then electroporated. 250 Â µl of S.O.C. medium was added to the cells immediately after electroporation. Each of the two suspensions was transferred to a 15 ml tube. The shaking incubator was then set to 225rpm and used to incubate the cells for an hour to allow expression of the acquired antibiotic resistance. 10 Â µl of the transformed sample was then added to 90 Â µl of S.O.C. medium. The plates containing the ampicillin were then used. 20 Â µl of each of the two diluted samples from step 7 was added to a plate. Even spreading of the sample on the agar medium was ensured. Using the non-shaking incubator, the plates were incubated at 37 ÃÅ'Ã…  C for a day and the results recorded. 4.0 Results and Discussion 4.1 Results Answers to Questions (1) Schematic of observations of the agar plates: Figure 1: Results as Indicated by the Agar Plates (2) Count the colonies and calculate the transformation efficiency. Number of colonies observed = 13 Figure 2: Calculation of Transformation Efficiency Using the formula shown in figure 2, Transformation efficiency = 1.78 1010 transformants/Â µg plasmid DNA 4.2 Discussion Answers to Questions (1) Define the vocabulary used in this experiment: transformation, electroporation, host, plasmid, and competent. -Transformation Transformation is a process of horizontal gene transfer whereby DNA present in the environment of a cell is taken up by the cell. In this experiment the transformation involves the uptake of a plasmid containing a marker that results in ampicillin resistance by E. Coli bacteria through electroporation. -Electroporation Electroporation involves subjecting cells to an electric voltage to create holes in the cell wall. External material can then enter the cell through these holes. Natural processes then cause the hole to close and return the cell to its original state. -Host An organism that harbours a parasite is called a host. -Plasmid A plasmid is circular extra-chromosomal DNA. -Competent A competent cell is one which can internalise DNA present in its external environment. Competence can either be natural or artificial. (2) State why E. coli is used in many genetic engineering experiments. The popularity of Escherichia Coli for genetic experiments is due to various reasons. Firstly, most E. Coli strains are non-pathogenic and pose no harm to humans. Safety is a significant factor in the laboratory and E. Coli use is generally safe. Secondly, E. Coli grow easily and can be duplicated through metagenics. Thirdly, their genetic make-up is relatively simple and can be manipulated with ease. Fourthly they have been extensively studied and a lot is known about them. This makes it easier for researchers and they therefore prefer to use E. Coli for genetic engineering experiments. (3) Explain why competent cells, ampicillin, and S.O.C. medium were used for the transformation. Competent cells are necessary as transformation involves taking external genetic material into the cell. If cells are not competent this cannot happen and the experiment cannot be carried out successfully. Ampicillin is an antibiotic. Specifically, it is a bacteriostatic for E. Coli. It helps distinguish between bacteria that have taken up the plasmid and those that have not. This is because the plasmid contains a marker that causes ampicillin resistance. E. Coli cells do not naturally contain the genetic sequence that causes ampicillin resistance. Thus, ampicillin selection is possible to distinguish between transformed cells and untransformed cells. S.O.C. medium contains the nutrients required to help cells stabilise after electroporation. Electroporation introduces holes into the cell wall of the cell and therefore causes destabilisation of the cell. S.O.C medium contains yeast extract and other nutrient sources that help the cell recover. Once the cell has recovered and if the plasmid has entered the cell during electroporation, the cell will multiply and give rise to a colony during the incubation period. (4) Explain the purpose of the controls in this experiment. The control in this experiment constitutes bacteria without the plasmid that inculcates antibiotic resistance. Without this extra piece of genetic information to enable the bacteria to mount defences against the attack of the antibiotic, ampicillin is this case, the bacterial cells will be unable to multiply in a medium that contains the antibiotic. The cells that were treated such that they could incorporate the plasmid DNA into their genetic make-up will be able to multiply in a medium where ampicillin is present as long as there are enough nutrients available for growth. Thus, the control helps us show that the DNA plasmid was indeed taken up and incorporated into their genetic make-up by the bacteria. The only way for E. coli to have survived with ampicillin present is if they had taken up the plasmid and transmitted it to all generations when they reproduced after uptake of the plasmid. Hence, the control serves to confirm uptake of the plasmid as well as its transmission to fol lowing generations by comparing it to cells in the control that did not have the extra DNA. (5) Explain how the colony growth relates to gene transformation. A colony of bacteria stems from the binary fission of one single bacterial cell. When bacteria reproduce vertical genetic transfer occurs whereby the offspring has the exact copy of the genetic material of the parent. In this experiment, bacteria are introduced into a medium containing the antibiotic ampicillin. E. Coli bacteria with their original genetic make-up will be unable to reproduce due to the presence of the antibiotic as they do not have the means necessary to resist antibiotic attack. This is what is expected in the control sample as ampicillin is a bacteriostatic.. The positive sample on the other hand has bacteria which have undergone horizontal gene transfer by transformation. The plasmid DNA that was used for the transformation process contains genetic code that results in E.Coli developing ampicillin resistance. Thus, bacteria that can incorporate this plasmid and pass it on to their offspring by vertical gene transfer can grow in the environment. This is how colony growth relates to gene transformation. (6) Describe how ionic strength of DNA solution affects electroporation. The ionic strength of DNA solution comes into play due to the electroporation stage where holes are created in the bacterial cell wall to allow uptake of the plasmid by transmission of an electric voltage. For this step, the ionic strength of the solution must be low. If the ionic strength is high, arcing will occur. Arcing is visible during the experiment by sparks and a sound like a micro-scale thunderclap. It can cause cell death as well as equipment damage. Thus, for the experiment to be carried out successfully and to safeguard the apparatus, the DNA solution must be of low ionic strength. (7) If your transformation efficiency is lower than 1 109 cfu/ÃŽ ¼g, conjecture and explain potential reasons for the low efficiency. The transformation efficiency is greater than the benchmark stated above. This corresponds to good transformation efficiency and indicates a successful transformation process. However, the close clustering of the colonies makes it possible that some of the colonies are satellite colonies rather than transformed colonies. The experiment could be repeated with a higher concentration of ampicillin to obtain more reliable results. (8) Discuss current and potential applications of gene transformation techniques in biotechnology. Gene transformation techniques play a crucial role in biotechnology. This is because gene transformation provides a method to produce copies of desired DNA sequences. This is especially useful in the pharmaceutical industry to develop medications that are target specific. Also, this could potentially lead the way to genetic engineering, where defects to the genetic code could be repaired and desired traits inserted through addition of the corresponding DNA sequences. Gene replacement therapy could prove to be the cure for nearly all diseases that take human lives contemporarily. In the future gene transformation could be used to engineer human beings and other animals and plants according to desired specifications. Genetic transformation is also used in the development of pest-resistant crops, which could potentially increase the productivity of the land. This could be key to feed the ever-growing population as the quantity of agricultural land decreases. Understanding the evolution of drug resistance could help us devise ways of preventing drug resistance as well as developing drugs that can overcome resistance. In this arena gene transformation plays an important role horizontal genetic transfer is a natural process in bacteria. 4.3 Sources of Error and Suggestions for Improvement There are a few sources of error that could result in incorrect conclusion being drawn from experimental results. (i) The number of colonies seen need not correspond to the bacteria that transformed. This could be due to the growth of satellite colonies. Large bacterial colonies will secrete beta lactamase, which is what causes ampicillin resistance. Thus, the area around the colony will contain this secretion and be ampicillin-free. A satellite colony could grow in this area from untransformed cells. To avoid this problem, the incubation period should strictly be restricted to 24 hours. Satellite colonies emerge after a delay. By ensuring that results arr recorded promptly, the interference in results brought about by satellite colonies can be minimised. Another method is to use a higher concentration of ampicillin. More time will be required to create a antibiotic-free zone around a colony if the concentration of antibiotic is high. (ii) Identifying the number of colonies can be difficult, especially if the size of the colony is miniscule. This could result in an incorrect calculation of transformation efficiency. In order to increase accuracy of results, a different selection marker can be used. Some selection markers have properties that can be distinguished by shining UV light and other such techniques which result in a high contrast. Using these markers may result in higher reliability of results. (iii) Distinguishing between colonies can be difficult if they grow close to one another and appear to be one large colony. Also, closer colonies would also result in a higher chance of there being satellite colonies. To minimise this problem, crowding on the plate must be minimised. For that, a higher concentration of ampicillin could be used, carbenicillin selection could be used instead of ampicillin selection (although expensive) or the nutrient dilution could be adjusted such that it discourages very rapid proliferation. 5.0 Conclusions The objectives of this experiment were to explore the phenomenon of gene transformation and the development of antibiotic resistance in bacteria as well as to inculcate the practice of sterile technique for handling bacteria. Gene transformation was observed with the development of ampicillin resistance in transformed Escherichia Coli bacteria. The bacteria not exposed to the plasmids containing the genes for antibiotic resistance did not grow in an environment containing the antibiotic while the transformed bacteria formed colonies in the same environment. A calculation of transformation efficiency returned a value of 1.78 1010 transformants/Â µg of plasmid DNA, which is greater than the threshold of 109, indicative of a successful experiment. However, the possibility of some of the 13 colonies of bacteria being satellite colonies as opposed to transformed colonies reduces the reliability of the results. Methods to increase reliability of results were therefore suggested. References 1. Port, Tami. (2008, June 14). Bacteria Horizontal Gene Transfer. suite101.com.

The Many Benefits of Hunting Essay -- Hunting Debate

When a Minnesota dentist killed a prized African lion named "Cecil" he received an onslaught of criticism and reignited the debate concerning hunting. Those who oppose hunting often have no understanding of the many benefits provided by hunting. Hunting provides free census animal data, as well as money to sustain clean rivers and forests and to manage wildlife populations. Animals are treated more humanely by a hunter’s bullet than by a slaughterhouse’s blade. There are two categories of hunters, the poachers and the traditionalists. However, people seem to classify hunters only by the practices of poachers. At first, I use to be one of them (people with no knowledge about the positive effects of hunting). I thought hunting was a merciless sport. Killing an animal for its antlers, fur, or their body parts. I saw hunters as unethical humans and so did most of the people I ran into. Then again this was before I did my research on hunting. After my research, I found some facts that were compelling. Hunting after all was not what I had perceived it to be. Nevertheless, there are still people that have the wrong impression about hunting because they don’t fully understand its meaning. Hunting has been around as long as humanity has existed. Hunting has played a key role in humanities fight for survival. Without hunting our ancestors may not have been able to survive. In his article, â€Å"Hunting and Human Values† author Paul Shepard states, that hunting may be a behavior that is inherent and about 95 percent of the time humanity has existed we have been hunters. Hunting has formed humanity and to take it away would take away a significant part of history and heritage. Hunting should be protected by laws such as Bill 273 s... ...nd a way for one to connect with nature in this modern world. Hunting has a positive impact on the wildlife and economy helping sustain animal populations while maintaining clean forests and rivers. It also helps the economy by generating revenue through hunting tags and permits. Works Cited "Division of Wildlife Resources Financial Overview." Utah Division of Wildlife Resources. 5 Oct. 2014.

Battered Womens Syndrome :: essays research papers

Battered Women's Syndrome: A Survey of Contemporary Theories Domestic Violence   Ã‚  Ã‚  Ã‚  Ã‚  In 1991, Governor William Weld modified parole regulations and permitted women to seek commutation if they could present evidence indicating they suffered from battered women's syndrome. A short while later, the Governor, citing spousal abuse as his impetus, released seven women convicted of killing their husbands, and the Great and General Court of Massachusetts enacted Mass. Gen. L. ch. 233, 23E (1993), which permits the introduction of evidence of abuse in criminal trials. These decisive acts brought the issue of domestic abuse to the public's attention and left many Massachusetts residents, lawyers and judges struggling to define battered women's syndrome. In order to help these individuals define battered women's syndrome, the origins and development of the three primary theories of the syndrome and recommended treatments are outlined below. I. The Classical Theory of Battered Women's Syndrome and its Origins   Ã‚  Ã‚  Ã‚  Ã‚  The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), known in the mental health field as the clinician's bible, does not recognize battered women's syndrome as a distinct mental disorder. In fact, Dr. Lenore Walker, the architect of the classical battered women's syndrome theory, notes the syndrome is not an illness, but a theory that draws upon the principles of learned helplessness to explain why some women are unable to leave their abusers. Therefore, the classical battered women's syndrome theory is best regarded as an offshoot of the theory of learned helplessness and not a mental illness that afflicts abused women.   Ã‚  Ã‚  Ã‚  Ã‚  The theory of learned helplessness sought to account for the passive behavior subjects exhibited when placed in an uncontrollable environment. In the late 60's and early 70's, Martin Seligman, a famous researcher in the field of psychology, conducted a series of experiments in which dogs were placed in one of two types of cages. In the former cage, henceforth referred to as the shock cage, a bell would sound and the experimenters would electrify the entire floor seconds later, shocking the dog regardless of location. The latter cage, however, although similar in every other respect to the shock cage, contained a small area where the experimenters could administer no shock. Seligman observed that while the dogs in the latter cage learned to run to the nonelectrified area after a series of shocks, the dogs in the shock cage gave up trying to escape, even when placed in the latter cage and shown that escape was possible.

Attending High School Essay -- Education Papers, high school experienc

High School Do you remember your high school days? High school for me has proved to be a learning experience and also a challenge. There are many lessons that can be learned. You can learn more about yourself, who your friends are, what kind of help is offered to you, and what your strengths and your weaknesses are. Attending High School helped build my confidence because my classmates were supportive, my teachers taught me how to study for tests, and the math tutors helped me overcome my fear of math. My classmates were supportive in many ways. I used to attend study groups for the subjects that I was struggling in. In these meetings with each other,we would study our notes and review the chapters that we would be tested on. My classmates would also tutor one another in subjects that they were strong in and others were weak in. My classmates would even talk and try to comfort me when I was having personal problems and help me get my priorities straight that took place outside of school. So without my clas...

Pepsi’s Strategy in Entering India Essay

?o had been trying to enter the Indian market for quite some time with no success. In 1988 Pepsi received a letter from George Fernandes, the General Secretary of one of the country’s leading political parties, Janata Dal. He wrote, â€Å"I learned that you are coming here. I am the one that threw Coca-Cola out, and we are soon going to come back into the government. If you come into the country, you have to remember that the same fate awaits you as Coca-Cola. † This scared PepsiCo a bit knowing that their rival was forced to leave the country in 1977 after the Janata Dal came to power. PepsiCo had to think of a way to get in without facing the same consequences Coca-Cola had to face. In May 1985, PepsiCo joined with one of India’s leading business houses, the R P Goenka (RPG) group, to begin operations in the India. The company, along with the RPG group company Agro Product Export Ltd. , planned to import the cola concentrate and sell soft drinks under the Pepsi label. PepsiCo’s decision linked its entry with the development and welfare of the state was aimed at winning the government over. The fact that Punjab boasted a healthy agricultural sector played a role in PepsiCo’s decision. PepsiCo claimed that it would play a central role in bringing about an agricultural revolution in the state and would create many employment opportunities. It promised to create 50,000 jobs in the nation. Pepsi began by setting up a fruit and vegetable processing plants at Zahura village in Punjab’s Hoshiarpur district. The plant then was focused on processing tomatoes to make tomato paste. Pepsi had a tough time convincing farmers to work for the company. Its experts from the US had to interact extensively with the farmers to explain how they could benefit from working with the company.

An Analysis of Robert Bresson’s a Man Escaped

Robert Bresson’s 1956 film A Man Escaped, is a film that is based on the true story of Andre Devigny, a member of the French Resistance who managed to break out of prison just hours before he was to be executed. In the opening sequence of the film the viewer is able to establish that the main character Fontaine, (Played by Francois Leterrier) has been escorted to prison. Fontaine notices that the men beside him are cuffed, but he is not. He tries to get away when the car stops but is recaptured and beaten upon the head.From his actions, the viewer is able to recognize Fontaine’s intelligence and that he is insistent on making an escape. The title of the film is a forewarning to the viewer and that â€Å"A Man Escaped†, and that warning causes the viewer to question if the title alludes to Fontaine, or another prisoner. The drama is built upon that upfront information and it is heightened the further into the duration the viewer gets, up until the final escape seq uence. The scene for analysis takes place at approximately Twenty minutes into the duration of the film.The scene opens with a medium shot focused on Fontaine amidst his isolation. Fontaine looks up toward the ceiling with a facial expression that reads as saddened or lonesome, which slowly fades out, and fades back in, to a medium long shot of the character crouching in a vulnerable position next to the door. A close shot of Fontaine’s face really shows his emotion, very saddened and depleted of hope. It appears that Fontaine is analyzing the wooden door.From his remarks, the viewer can gather that the character has previous knowledge of wood and that dismantling the door is a possibility in his plan to escape the prison. Bresson is persistent on the close-up of the potential escapist’s hands, feeling the wood, working with tools, etc. The character receives an iron spoon, an item that will aid him in moving the panels in the door. Followed by another close-up of the main characters hands, sharpening his new tool, which dissolves into the next medium shot of him standing in his prison cell.Fontaine is able to pry the panels of wood apart. Fontaine hides his new tool and moves toward the window in his cell, The camera pans up, following him, and the scene fades out. This is one of the most important scenes in the film, and really is the turning point for Fontaine because he acknowledges the possibility in getting through his prison cell door and acquires a tool that is capable of helping him â€Å"dismantle† the panels in the door. I think this gives him a small amount of hope and a goal to work towards.Bresson’s minimalist approach to the cinematography intensifies his use of non- diegetic sound in the film. Bresson uses sound beyond the image, to inform the viewer of actions going on around Fontaine’s prison cell. like footsteps outside the cell or noises made by other prisoners. Sound is used to put emphasis on Fontaineâ⠂¬â„¢s actions, like the chiseling of the panels or the sharpening of the spoon. As with the images, dialogue is reduced to the essential. Fontaine does the narration in the film and he only indicates the most important details to the viewer.

Birth Weight And Parity Relationship Health And Social Care Essay

World Health Organization defined low birth weight as a per centum of unrecorded Born babies that weigh less than 2500 g, for a given clip period. Infant mortality addition particular to deliver weight if they weigh less than 2500 gms ( 1 ) . Low birth weight is caused by short gestational age or intrauterine growing deceleration or a combination of both. Low birth weight is an of import cause for infant mortality in United Kingdom ( 2 ) and can impact baby ‘s wellness in approaching old ages. Birth weight is associated with perinatal mortality and morbidity every bit good as with diseases like type 2 diabetes and cardiovascular disease in maturity ( 3 ) . New born babes with birth weight of less than 2500g history for 7 % of all unrecorded births in developed states ( 4 ) . Low birth weight varies widely in adult females of different socio-economic position e.g.in early 1890ss, in England and Wales the per centum of low birth weight births was 8.2 % in unskilled societal categ ory V versus 5.4 % in professional societal category I based on the business of the male parent ( 4 ) . Smoke is the 1 of the major modifiable hazard factor lending to low birth weight of new born babes. Babies born to female parents, who smoke, weigh on mean 200g less than babes born to female parents, who does non smoke. Harmonizing to Messecar et al the tobacco users have twice the incidence of low birth weight as compared to non-smokers ( 7 ) .Socio-economic position strongly affects smoking surcease in gestation. Womans with lower income, instruction and unemployed are far more likely to go on smoking than adult females from higher socioeconomic position groups ( 8 ) . Smoking surcease reduces the prevalence of low birth weight and increase birth weight among pregnant adult females who stop smoke as a consequence of successful intercession ( 9 ) . We conducted a prospective observational survey, in which we recruited pregnant adult females showing to the labour ward of local District General Hospital in active labors in May 2004.We included adult females who were willing to take part with singleton gestation dated by ultrasound. Mean age of participants were 31.33 ( old ages ) .Women who were non in labor, non willing to take part, with learning disablements, terminal unwellness and with Intrauterine deceases or still births at the clip of presentation were excluded. We gave eligible adult females the elaborate information cusps sing our survey and a trained wellness attention professional took consent from willing female parents. We used structured signifier to roll up the information and used instance notes of voluntaries to roll up this information. We collected informations on maternal age ( uninterrupted variable ) , gestational age ( uninterrupted variable ) , on smoke position ( categorical variable ) , BMI ( uninterrupted variable ) and gender of new born ( categorical variable ) . General demographic information was besides collected. We used standard mensurating graduated table in labour ward to enter the birth weight ( uninterrupted dependant variable ) of the new Born and used units of gms for weight measuring. Data was analysed with the aid of statistician based at the section of Basic Health Sciences University of Leicester. We used SPSS16 package bundle to analyze the information. Over a period of 30 yearss we invited all eligible adult females to take part in our survey from the labour ward of local District General infirmary, merely 150 volunteered to take part. In our informations one individual has all losing values except birth weight, there were two other outliers in birth weight values, these were non justifiable i.e. birth weight of 20g and 1265g.We did informations cleansing by canceling these three values. Mean birth weight was 3390 gms runing from 2300g to 4520g with standard divergence of 487.37.Womens age scope was from 19years to 43 old ages with average age of 31 old ages. Gestational age among participants ranged from 24weeks to 43 hebdomads with mean of 39 and standard divergence of 2.80.Out of 149 adult females 23 were tobacco users and 126 did non smoke during gestation. Majority of tobacco users in our survey were multiparous i.e. 73.9 % . Approximately 55 % primiparous adult females and 45 % multiparous adult females did non smoke during g estation. Among the new born babies 76 were males and 73 were females. Birth weight is a dependent variable and it is usually distributed. Parity of female parent is one of the forecasters and is besides usually distributed. Pearson coefficient trial was important ( important 2 tailed P value=0.01 ) demoing significance correlativity between two variables. We used parametric trial i.e. independent T trial and found that average birth weight of new born in primiparous ( n=74 ) was 3288g which was 205g ( 95 % CI-49.4-361.1 ) less than the average birth weight ( 3493 ) of new Borns of multiparous adult females ( n=73 ) .The Levine ‘s Test is non important ( p=0.92 ) , the two discrepancies i.e. primiparity and multiparty are non significantly different and we can presume that the discrepancies are about equal. In our T trial the value of T is 2.63.We have 145 grades of freedom and 2 tailed significance= 0.10 which is more than.005 rejecting our void hypothesis. We checked the relationship between gestational age and birth weight and found this to be linear.We used spearman ‘s trial to see this relationship and found this to be important ( p value 2 tailed =0.01 ) . Birth weight is non dependent on gender of babe ( p value- 0.028 with Mann Whitney trial ) .The interaction between para and smoke to impact the birth weight is non important ( p=0.858, F=0.32 ) and is no more than would be expected by opportunity. Test for difference in average birth weight by gestational age is important ( p=0.00 ) .Test for difference in average birth weight by Body mass index ( p=0.76 ) , smoking ( p=0.89 ) is non important. Dependent variable is birth weight which is usually distributed. This is prospective survey look intoing the association of babies birth weight with para of their female parents. In our survey consequences Infants birth weight ranged from 2300grams to 4520grams. Harmonizing to WHO any infant born with a weight of less than 2500 gms is considered to be of low birth weight.There are many cause of low birth weight in babies including female parents body aggregate index, female parents age, nutritionary and smoke position ( 5 ) .We found that infant born to primiparous female parents weigh less so multiparous adult females. In subsequent gestations birth weight of babies increases our consequences are consist with finings of Macleod S et Al who found that birth weight additions from para 1 to para 3 but they besides found that birth weight dropped markedly in higher para group ( 13 ) ( 10 ) . We did non analyze the birth weight relationship as per figure of para as they did and we felt that this is one of failing of our survey. It is observed that mat ernal age and para of female parent affect birth weight by interfering with intrauterine growing, non by impacting gestational age ( 13 ) . Different theories were proposed in literature to explicate the intrauterine growing deceleration in female parents of different age and para groups. Many research workers reported that immature female parents in their teenage could non run into the demands of their growth fetus because of their ain turning organic structure demands and therefore taking to intrauterine growing deceleration ( 13 ) . Same sort of account can be given for multiparous female parents as nutritionary demands change over clip. There are other physiological factors which could play a portion in birth weight of babies in subsequent gestations like co-existing unwellness in female parents ( 14 ) , pregnancy attention etc and this was non looked in our survey. Appropriate for gestational age is term used for Babies whose weight is appropriate for their gestational age, big for day of the months is the term used for babies heavier than their gestational age, and those smaller than expected are considered little for gestational age. We looked at the relationship of gestational age with infant birth weight. We found that this was important and it was straight relative i.e. with increasing gestational age, birth weight besides increased. This is another country for farther research to see any relationship between para and gestational age of babies. We besides noticed that at both extremes of maternal age i.e. in teenage female parents and in older adult females birth weight of babies tends to be on lower side. In our survey sample minority of adult females continued to smoke during gestation.Because of our little sample size we could non happen any association between smoke and birth weight, nevertheless it is good known fact that smoke is an of import cause of intrauterine growing deceleration and low birth weight of babies. We could non happen any association between gender of new born babies and their birth weight.

Throwaway Confidential Informants Essay

The article, â€Å"The Throwaways†, by Sarah Stillman, is an account of confidential informants being used as inexpensive and off the record pawns in the drug war. A confidential informant is a person who has been caught for a crime, usually illegal narcotics, and has been offered to have their slate wiped clean or their punishment reduced if they help bust a higher up criminal. The police treat these informants as if they are nothing else but a tool to catch the criminals at the top of the food chain. The police do not stop to think that the informants are often productive people in society, even if they decide to partake drug use. I have a close friend who was asked to be an informant after being busted with just a small amount of marijuana. I strongly advised against this for his safety, and my friend instead had to spend nearly four thousand dollars on a lawyer. It is unjust and immoral for police officers to use these people with no formal guarantee that their charges will be dropped, as well as putting them in extremely dangerous situations. â€Å"The Throwaways† is an article about four young confidential informants who had their lives cut short because they decided to cooperate with law enforcement and help bust drug dealers. Every single informant’s fate led 6 feet underground. Rachel Hoffman was a twenty-three year old girl who had plans to go to culinary school and open a new type of rehabilitation center. Rachel was found dead the next day fifty miles from where the cops were supposed to be tracking her every move. Lebron Gaither testified against a man in court and was then ordered to try and buy narcotics from the same man he had just testified against; he was tortured, shot with a handgun as well as a shotgun, ran over by a car, and then dragged by a chain into the woods. Shelly Hilliard was caught with a half ounce of pot, threatened with prison, and agreed to be an informant. Hilliard’s body was found on fire beneath a mattress on a service road. The last informant in the article, Jeremy Mclean, agreed to be an informant because he did not want to bring disgrace to his family name. The police continued to make Jeremy bust drug dealers until he helped lead to the arrest of a heroin trafficker. The officers said that the heroin trafficker, William Vance Reagan, Jr., was harmless and not to worry. Reagan shot Jeremy in the back of the neck 3 times and once in the face. He was sentenced to life in prison without parole (Stillman). Narcotics officers use informants  as a disposable tool to get to people, or places that they cannot get to alone. According to the article, over eighty percent of drug busts involve informants (Stillman 38). There are usually no contracts and the informants have to trust that the officers will keep their word. I think that this is insane and it endangers the lives of mostly young people who have their entire life ahead of them. At the time, the opportunity to be a confidential informant and having all of their charges dropped seems like a better option than time in jail or huge fines. It is too dangerous to bust a drug dealer. The word would get out that they got arrested, and the informant would be the number one suspect. I have a close friend who was smoking pot at a Wiz Khalifa concert in his car before going in, because he had been told that there were cops inside and that the security guards searched you before you went in. While smoking he saw two men walking up by his car, one a big strong white man and the other a smaller African American man. As they walked past his car, he took a sip of his drink because his throat burned slightly from the smoke. The two men saw him do this, pointed at his car and walked off. My friend felt that something was wrong because of the way they pointed at the car, so he got out to go into the concert. The next thing he knew, both of those men had chased him down and were interrogating him about what he had been drinking. He did not look stoned, because he had put in eye drops and said he wasn’t drinking anything but a coke. The men pulled out their badges and fifteen other cops circled around him. They reached in his pocket, took out his keys and unlawfully searched his car, because he had been seen drinking a coke. When they found marijuana in the car, they were surprised. They didn’t read him his Miranda rights nor have probable cause to search the car. The smaller African American man asked my friend to step aside and asked him if he knew where he could get an ounce or more of pot. He said yes and then he offered for him to be an informant, he gave him his number and said to call him J. The man said that this is how it would go down if he agreed; J would give my friend money and he would walk in and buy a gram of pot, walk out and give J the marijuana. Then a couple days later he would have to introduce J to the dealers and they would both buy some marijuana. Then J would attempt to get over an ounce of pot. After a couple weeks passed, the police would come to the dealer’s house and arrest him. My friend could have had his charges dropped completely. Although he could have  also ended up like Jeremy and perform more sting operations, or even worse dead. There are no contracts, it is completely based on the cop’s word and that is a huge problem. You never know what could set a person off and make them mad enough to kill you. For example; in a neighborhood near mine a drug dealer shot and killed four teenagers because they did not pay him for two grams of weed worth forty dollars. I think that using confidential informants at all should be outlawed due to the excessive risk in every situation, but I am very biased because of my friend. The current law regarding informants requires special training for the officers, t he informant’s age and emotional state to be considered, and for the level of risk to be taken into account. (Stillman 47) There are still no real guidelines, just certain things that the officers must consider. There either needs to be much more strict guidelines, such as the informant must be a legal adult, or the use of confidential informants should be made completely illegal. The tragic stories that are presented in this article should be enough for anyone with a conscience to know that the use of informants is wrong. The police use informants as a cheap way to bust dealers by scaring the people into cooperating. I have a personal experience in my life that impacts my opinion on the use of informants. My friend could have been killed while doing the law enforcement’s dirty work, because he decided to smoke a small amount of marijuana. The decision to become a confidential informant should not be one of the last decisions a person must make in his or her life. It should be completely illegal for trained police officers to endanger the lives of citizens by offering them to be an informant. I believe police officers should protect and serve, that means not aiding the deaths of ordinary people. Works Cited Stillman, Sarah. â€Å"Re: The Throwaways.† New Yorker. N.p., 17 Sept. 2012.

Change and Conflict Management in Nursing

Change and Conflict Management in Nursing Jon Teegardin Change and Conflict Change and conflict occur in all aspects of our society. In nursing, it is important to identify and embrace change, address and resolve conflict, and do so in an effective and efficient manner. This paper will present descriptions of change theories, conflict theories, and how a nurse’s ability to handle both can enhance or hinder effective leadership. Additionally, the leader as a change agent will be discussed. Change Theories While there are numerous theories of change that exist, in the profession of nursing there are three main theories that are consistently seen throughout the healthcare industry. These theories are Lewins theory of change, Rogers change theory, and Spradley’s change theory. Lewins change theory Probably the most recognizable theory of change is that presented by Kurt Lewin. His theory involves three stages to change: unfreezing, moving, and refreezing (Stolley, 2005). Two forces are present in this theory, the driving force, or those pushing for a particular change, and the resistant force, those who are resistant to the change. For change to occur the driving force or agents for change, must be stronger than the resistant force. In the unfreezing stage, the driving force develops a method that allows people to let go of the current, unproductive way of doing something. By finding this method, individual resistance to the change is overcome. In the moving phase, individuals are encouraged to change their way of thinking, feeling, or behavior to the new method. Finally, in the refreezing stage, this change becomes the new habit and ultimately the standard operating procedure. Lewins theory is also referred to as the force field theory that states an organization attempts to maintain a state of equilibrium between change forces and restraining forces (Swanson, & Creed, 2014). Change agents are the forces for change and must overcome the restraining forces to make the change successful. Rogers change theory Everette Rogers’s theory is a modification of Lewin’s change theory and involves five stages. The stages are awareness, interest, evaluation, implementation and adoption (Boston University School of Health, 2013). Roger’s theory is typically applied to long term projects. In the awareness stage, individuals are exposed to the new idea or process but lack all of the information about it. In the interest stage, the individual is interested in the new idea and seeks out additional information. The next stage is the evaluation stage where the individual determines how to apply the idea or process to their situation and decides whether or not they want to try it. The implementation stage occurs when the individual decides to make full use of the idea or process. Finally, in the adoption stage, the individual decides to continue to use the new idea or process. Roger’s theory is an example of social cognitive theory. Change does not occur im mediately among all those presented with the change. There are actually five groups of people that implement the change over time. These groups are innovators who are leaders that embrace the change immediately, early adopters who are also leaders but will follow innovators, the early majority who are the bulk of the followers, the late majority who include skeptics of the change, and finally laggards who are resistant to change (Kaminski, 2011).
