Cold War Final - Essay Example Somewhere in the range of 1947 and 1991, the Soviet Union looked up to the United States and its partners in a political strain that undermined the tranquility of other uninvolved countries. With the two gatherings having atomic capacities, the world about endured because of contrasts. While none of the two really occupied with military assaults against one another, dangers were given as conciliatory lines seethed on (Totten, 2013). Shockingly, despite the fact that the line included just two gatherings, whatever else occurred on the planet was to a great extent directed by the situations developing between the two.

Totten (2013) claims that the status of US training and the world everywhere was enormously influenced by the deadlock. Before the war heightened, the impacts were not felt that much yet that circumstance changed as the power of the war took higher than ever.

Agoraphobia Symptoms and Treatment Options

Agoraphobia Symptoms and Treatment Options More in Panic Disorder Symptoms Diagnosis Treatment Coping Related Conditions Currently, panic disorder is diagnosed as occurring with or without agoraphobia. It is also possible to be diagnosed with agoraphobia without a history of panic disorder. Doctors and other mental health providers use the criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders (DSM) to determine which diagnosis is most appropriate. Below you will find information straight from the DSM, including diagnostic criteria, features, prevalence, and treatment options for agoraphobia. This information covers five common FAQs about agoraphobia that you should know. What Is Agoraphobia? Agoraphobia is defined as a fear of having a panic attack in a situation where it would be challenging or embarrassing to escape. This fear often leads to persistent avoidance behaviors, in which the person begins to stay away from many places and situations in which they fear panic may occur. For example, some commonly avoided circumstances include driving a car, leaving the comfort of home, shopping in a mall, traveling by airplane, or simply being in a crowded area. Due to these avoidance behaviors, the life of a person with agoraphobia can become very restrictive and isolating. Agoraphobia can greatly affect a person’s personal and professional life. For example, heightened fears and avoidance behaviors can make it difficult for a person with agoraphobia to travel for work or to visit with family and friends. Even small tasks, such as going to the store, can become extremely difficult to do. Fear and avoidance can become so severe that the agoraphobic person becomes secluded to their own home. How Is Agoraphobia Different From Other Phobias? The avoidance behaviors present in agoraphobia differ from the diagnostic criteria of a specific phobia. For instance, a person with agoraphobia may avoid traveling by airplane due to a fear of having a panic attack on a plane and not necessarily due to aerophobia, or a fear of flying. Similarly, an agoraphobic may avoid crowds, fearing the embarrassment of having a panic attack in front of a lot of people. Such a fear is not the same as social anxiety disorder, which is a separate mental health condition that involves anxiety about being negatively evaluated by others. Can Agoraphobia Occur Without Panic Disorder? Although rare, it is possible to be diagnosed with agoraphobia without having a history of panic disorder. When this occurs, the person still has a fear of being stuck in a situation where escape would be difficult or humiliating. However, they do not fear to have full-blown panic attacks. Rather, they are afraid of having some of the frightening physical symptoms of panic and anxiety or other intense physical issues, such as vomiting or having a severe migraine. For instance, the person may be afraid that they will lose control of their bladder in public or faint without any help being available. Prevalence Approximately one-third to half of those diagnosed with panic disorder will also develop agoraphobia. The National Institute of Mental Health (NIMH) reports that agoraphobia occurs to approximately 0.8% of adults in the U.S. population in any given year. This condition typically develops in adulthood. However, agoraphobia can emerge earlier in adolescence. Treatment Options If a person does develop agoraphobia with panic disorder, symptoms typically begin to occur within the first year that the person starts having recurring and persistent panic attacks. Agoraphobia can get worse if left untreated. For the best outcomes in managing agoraphobia and panic symptoms, it is important to seek treatment as soon as symptoms arise. Treatment options typically include a combination of both medication and psychotherapy. The treatment process may include some systematic desensitization, in which the agoraphobic person gradually confronts avoided situations. Many times, the person will fare better in facing their fears if accompanied by a trusted friend. Through the support of family and friends and professional help, a person who is struggling with agoraphobia can begin to manage their condition. Through medication and psychotherapy, a person with agoraphobia can expect to eventually experience fewer panic attacks, fewer avoidance behaviors, and a return to a more independent and active life.

Discrimination Affect On Individuals and Society - Free Essay Example

Sample details Pages: 5 Words: 1403 Downloads: 4 Date added: 2019/04/01 Category Society Essay Level High school Tags: Discrimination Essay Did you like this example? America is the greatest, freest and most decent society in existence. (Dinesh DSouza) If this were to be true, why do poverty, violence, crime, and discrimination still exist? Moreover, discrimination is an issue of great consequence. Discrimination: the unjust treatment of different people or things, especially on the grounds of race, age, or sex (English by Oxford Dictionaries). Don’t waste time! Our writers will create an original "Discrimination Affect On Individuals and Society" essay for you Create order Hispanic discrimination began around 1848 when the United States won the Spanish-American War. If America is a great, free, and decent society, why is discrimination still a problem today, after all of these years? According to a Pew Research Center survey on race in America, 50% of high school graduates said they had regularly or occasionally experienced discrimination. The discrimination against Hispanic high school students is a major issue that can lead to mental health issues such as depression, aggression, and low efficacy. One of the major health issues caused by discrimination in high school is depression. The young minds of teenagers are fragile and sensitive, and discrimination drastically affects ones mindset. A study led by Selcuk Sirin, associate professor of applied psychology at NYU Steinhardt, surveyed 173 Hispanic teens, grades 10-12 in New York City high schools. There were higher depression issues found in students in the eleventh and twelfth grade. The increase in symptoms of depression was a result of discrimination-related stress (Harrison 6 7). Depression leads to changes in appetite, sleep, energy level, concentration, and daily behavior. It also leads to other unhealthy issues, such as low self-esteem, isolation, and suicide. The outcome of these negative effects on teens will follow them in the future when entering society. Notably, some people believe the cause of depression is actually created outside of school. They believe that it may result from disputes or personal conflicts f rom home. This is proven incorrect by the article Discrimination Leads to Depression in Minority Children by Elements Behavioral Health. The article claimed, although personal reasons may be a cause, discrimination at school is more likely the cause of depression in students. The most common forms of discrimination were by being called insulting names or being accused unfairly of disrupting the class. The population of Hispanic students is continuously rising in America. These teenagers are the next growing generation; they are the future of society. Due to discrimination, their newly developing minds continue to be contaminated. This corruption prevents Hispanic students from entering the world with a full, healthy mindset. The second major issue caused by discrimination in Hispanic students is aggression. The result of aggression in students from discrimination can lead to violence, which includes bullying, threats, and shootings. Aggression could also cause other behavioral issues such as alcohol consumption and drug use. The article, The Relationship Between Community Violence, Ethnic Discrimination, and Aggression claimed research reported exposure to higher levels of ethnic discrimination was positively related to aggression (?–zdikmenli-Demir 8). The outcome of the aggression and experience of discrimination could lead to threats of others and puts teens at a higher risk of criminal activities. The outcomes not only affect those Hispanics but affect other students around them, as well. An opposing view of aggression would be that it only affects the person and not those surrounded by their presence. The aggressive behavior from one student involves others since the behavior can consist of a rguing with a teacher, blaming others, physical fighting and the disruption of class. Students who are discriminating are not punished for their actions. When a student discriminates, the ramifications that follow are simply receiving detention or a short-term suspension. This allows them to continue with those behaviors since there is no authority over them. Thus, a cycle of discrimination, consisting of those who get away with their actions, is created. When the victim disrupts class from the anger held inside, not only are they held accountable, but they also prevent themselves and others from learning. Those who are discriminated are then forced to believe they are to blame for their aggressive behavior which can lead to dangerously low self-esteem. The consequences of discrimination acted upon Hispanic students, in turn, affects society and can brutally affect the country. The increase of criminal activity, violence, exposure to alcohol and drug abuse pollutes the good of socie ty. Those who are affected by aggression from discrimination are most likely to pass down their traits to their children. With a growing population in America, the risk of discrimination to Hispanics affects future generations in which, the rotting of society will continue. The third mental health issue caused by discrimination against Hispanic students is low efficacy. Discrimination to a student can take a toll on their mental health by leading to a lack of confidence and efficiency. Lacking efficiency affects the persons ability to overcome obstacles and makes them more likely to cease effort early and fail. The authors of a 2011 Child Development study, based at the University of Texas at Austin and UCLA, noted, when students lose confidence in themselves, they lose their ability to be self-efficacious (Thaler 2). The level of confidence one has contributes to how they approach goals, challenges, or tasks. Students having low self-efficacy instills difficult tasks to be avoided instead of mastered, further blocking them from reaching their potential. Individuals who are discriminated have low self-efficacy and are more likely to have unsuccessful outcomes in the future, which also diminishes their ability to achieve goals and tasks. A distinct opini on regarding efficacy would be that it does not affect the students education. To be efficient means to achieve maximum productivity with minimum wasted effort or expense. Since low efficiency is an effect of discrimination, it affects the students amount of productivity. Having low productivity helps create a loss of interest to input effort and becomes a cause of the students struggle academically compared to their peers. A Hispanic student having low efficiency discourages their growth and skill development in which they may find tasks to be harder than they may be. Low self-efficacy strongly relates to their work performance in the future. Lacking confidence and low efficiency allow students to doubt themselves. In a society that is constantly moving and constantly advancing, when one has low efficiency, it negatively affects their ability to advance and create a stable living condition in the future. When this occurs, a cycle of slacking students is created and passed down amon g new generations, affecting the productivity of society. Depression, aggression, and low efficiency are three mental health issues that result from the discrimination of Hispanic high school students. Due to harsh experiences, high school students fresh, evolving minds are damaged, thus preventing them from growing to their full potential. Constant discrimination against Hispanic students calls for the build-up of aggression, because of this, students grow accustomed to becoming violent. Following the increase of violence is room made for criminal activity to rise, creating a dangerous environment. As students continue to face discrimination, they encounter the loss of efficacy, thus resulting in them deprived of overcoming obstacles at the best of their ability. These factors of discrimination altogether affect the students ability for full growth when becoming an adult. It deprives them of making sensible choices for the future. If those Hispanic teens cannot succeed in the future, where does that leave society? Discrimination not only i mpacts the individual but as a consequence, will lead to the disunity and endangerment of the peace of the society. With the expanding population of Hispanic teens, if discrimination continues to rise, the society will be bound to dissolve. Works Cited The Brutal History of Anti-Latino Discrimination in America.

Comparing The Crucible and Salem Witch Trials Essay

The purpose of my paper is to compare and contrast Arthur Miller’s The Crucible with the actual witch trials that took place in Salem in the 17th Century. Although many of the characters and events in the play were non-fictional, many details were changed by the playwright to add intrigue to the story. While there isn’t one specific cause or event that led to the Salem witch trials, it was a combination of events and factors that contributed to the birth and growth of the trials. Some of these events included: a small pox outbreak that was happening at the time, the revocation of the Massachusetts Bay Colony charter by Charles II, and the constant fear of Native attacks. These helped in creating anxiety among the early Puritans that†¦show more content†¦A few years later, he was called before the House Committee on Un-American Activities.

A man’s career could be ruined if he were merely asked, â€Å"Are you now or have you ever been a member of the Communist party?†Ã¢â‚¬  In 1954, Miller was denied a passport by the State department when he had planned to attend the opening of his play in Brussels and this was not the end of Miller’s government troubles over the next few decades. He was called before Representative Francis Walter’s Committee on Un-American Activities where he talked to the members on various subjects. At this encounter, Miller was asked about his attendance at a Communist writers’ meeting in which he admitted to attending but was not willing to name any other attendees. Refusing to answer the questions of the committee, Miller was tried and found guilty on two counts of contempt. Sadly though, Arthur Miller passed away in 2005 at the age of 89.

Why are there so many more male offenders than female Free Essays

Why are there so many more male offenders than female? Crime is generally committed by the male pursuit but more and more women are starting to play a role init. There are many Factors which contribute to why there are more male prisoners than female. This assignment will go into depth and detail discussing all evidence behind it. We will write a custom essay sample on Why are there so many more male offenders than female? or any similar topic only for you Order Now It will overall provide an explanation to why there is more criminal behaviour in males than females. This will include criminological theories which will be put forward to explain criminal behaviour in both genders. Firstly the key issue surrounding this topic is why there are more male prisoners than female and make sense to why this is. Generally the crimes female commit differ from male criminality. Women appear as offenders in all categories of offences from the least serious to the most serious (Hedenson, 1989). Robert 1977 in United States males are more dominant in burglary, drunkenness, auto theft, robbery, driving under influence, posseion of weapons and sex offences. Females predominate in offences relating to prostitution. Murders are more predominant in male’s activity. (Wilson) majority of victims of murders are males. 2001 indicate that 42% of female. The crime committed by women has more of an emotional characteristic then those committed by men. The pattern of women committing fewer crimes than men continues as there are only 19% of known women offenders. Women are more likely experience domestic violence. Their current or former partner murders two women every week and 44 % of violent incidents against women are domestic. Facts and Statistics are looked at thoroughly in England and Wales by the Home Office and provide the following picture of male and female offending. In 2002; 81 per cent of known offenders were male, and 19 per cent female. Soothill et al (2002) have estimated that 35 per cent of males born in 1958 will have had a criminal conviction by the age of thirty-five; and for women the figure is 9 per cent. According to the statistics of female offenders in prison, most are in for drugs, theft and handling stolen property offences, these accounts for 60% of known female offenders. 15% of sentenced female prisoners have previously been admitted to a psychiatric hospital and over 40% of sentenced women prisoners have been reported as being dependent on drugs in the year before coming to prison. An estimated 20% of women in prison have gone through separation from their parents and have spent some time in care. There have been major controver sies on the different roles played by each gender in accordance to crime. Theorists have been questioning this by looking at social, biological and psychological explanations. They have been used to develop theories to explain why females commit crime and why they commit less crime than males. Theories have over the years developed progressively further by the body work on gender in criminology and social sciences in general. Theorist has stated the casual role of biological and psychological factors in female crime show masculine factors. Cesare Lombroso puts forward the explanation that ‘criminals are atavistic throwbacks and that crime results from a reversion to their more primitive state’. He studied the skulls and bones of women criminal and prostitutions. He also compared factors such as history of both criminal and non-criminal females.Lombroso declared that ‘any physical characteristic that were more common in the criminal group were atavistic’. He viewed women as a’ lower form of life than men.’ Judging from his experiences (and prejudices) lead him to believe that criminals were different physically from normal people and had physical characteristics of savages and inferior animals. The term ‘Born criminals’ that had atavistic qualities and had committed crimes due to mental conditions e.g. general paralysis, dementia, pellagra, alcoholism, epilepsy, idiocy, or hysteria. He also claimed that women are able to adapt to unappealing environment than men hence why they turn to prostitution as an alternative to crime. Lombroso and Ferrerero book titled ‘The Female Offender’ described females as deceitfulness, cunni ng, spite, amongst others which they claim none of which appeared among males. This indicates that criminal females are more genetically like males than none criminal females and such biological abnormal.Moreover, according to Tarde, Lombroso’s theory did not explain the lower rate of criminality among women having the same stigmata. Other theorists such as WI Thomas accepted Lombroso’s account of inferiority and passivity of women, however he did not agree on the theory that criminal women are more like men. In his book, ‘The Unadjusted Girl’ blames female crime on the traditional constraints placed upon them. Resulting from these women have the desire for recognition, and in order to obtain this many females get involved in illegal activities. He discusses that everyone has four main duties in life, desire for new experiences, security, and response, and recognition. Thomas considered that women maintain their virtue until marriage, but these women used their sexuality to obtain whatever they want. Women were seen having feeling confined under monogamy, and having a lot sexual energy, this was released in criminal acts. Sigmund Freud suggested that the explanation to why women commit crime may be due to not being able to fully resolve the Oedipus complex. As they have a great deal of need for the males to approve them they rule out the risk by committing crime. The exceptional female who does offend is seen as suffering from extreme penis envy and, in a desire to be a man, takes an aggressive, non-conforming attitude that may result in criminal behaviour. Freud believed that all individuals are born with a potential to become a criminal due to basic instinct leading to anti-social behaviour. By analysing boys and girls Freud came to the conclusion that due to genetic differences women are more passive than men. Freud agreed with Lombroso in that female criminality rejects passivity and tries very hard to be like men. However, whil e, in theory, women have similar opportunities as men to commit crime these may be limited by other factors such as employment, as fewer women than men work, less opportunity exists. Women are also more likely than men to have primary responsibility for are child-care, which restricts opportunities for various types of criminal behaviour. It is perhaps true that female crime can often explain as women’s unusual response to lack of opportunity and school failure. It is a desperate attempt to escape from poverty rather than, as in the case of many men, an aggressive response to their social situation. Courts may deal more leniently with females. However, it appears that when women commit crimes that go against male stereotypes of femininity, women tend to be more harshly punished than men are. This can be seen with crimes involving violence. Scientists have suggested that the brain differences between male and female is an essential reason why women are more likely to stay out of harm’s way. Current research has demonstrated that females, on average, have a larger deep limbic system than males. Due to this, women are more in touch with their feelings; they have an increased ability to bond and are connected to others.Allen’s study is exceptional in suggesting that violent women offenders received more sympathetic sentences and justice than men did. Typical Cultures where the female stays at home doing housework and looking after the children also reduces female crime rate as there would be less opportunities to commit crime. Females undergoing domestic violence due to culture can however commit one of the biggest crimes. True story by Kiranjit Ahluwalia and Rahila Gupta describes how Kiranjit went through 10 years of domestic violence and eventually loses it one night and sets her husband on fire whilst he was sleeping. Though this story is based on the life of Kiranjit Ahluwalia, parallels can be drawn to the lives of many women who are the victims of domestic violence. It also shows how culture, family value and honour are misconstrued and misinterpreted to allow women no freedom and men no restrictions. Gang culture affects the skew of sexual assaults to being predominant in male activity, violence and rape is cheered on in males as masculinity. Another factor to consider is feminisation poverty (currie 1985). High proportions of women tend to commit crime such as burglary in order to put food on the table for their children for the same reason benefit fraud could be committed. Survey conducted 1994 women in prisons are mostly mothers who have committed an offence for the following reasons; having no money (54%) mixing with the wrong crowd (46%) need to support children (38%) drink and drugs (35%) family problems(33%) having no job (33%) however males tend to engage in burgulary for more or less the same reason. Pasko (2004) stated young females tend to commit crime through the rough experience they live through. An example would be young female runaways who experience abuse and then being returned home by caring professionals who end up experiencing more abuse. Age is another factor that has a relationship between offending behaviour and sex. Tarling 1993 showed criminal statistics for England and Wales showing that the peak age of young males offending was 18 in 1990 and for female it was 15. Males are more likely to commit offences that would be committed by young people offenders were as females tend to commit crime that are done by older people. Females may be committing crime committed by older people due to the family responsibilities they may have therefore this might be re-labelled a ‘crime and responsibility thesis. More Males are likely to commit crime at a younger age due to the environmental influences they encounter as they develop through age. Influences such as violent video games, TV, films and violent role models may play a key role to why there are so many more male offenders than females. â€Å"By the time the average U.S. child starts elementary school he or she will have seen 8,000 murders and 100,00 acts of vio lence on TV.†(New Scientist, 2007). The relationship between gender differences, and criminal behaviour is complex and varied, there are no simple answers. A number of factors must be taken into account, and the environmental influences and cultural traditions can be seen as the most important ones. Bibliography Home office. (2003). Gender crime.

How and why is federalism enshrined in the US Constitution free essay sample

How and why is federalism enshrined in the Constitution? (15 marks) Federalism is the system of government in which power is dispersed between central and state governments, each level of government having different responsibilities. Article four of the constitution is devoted to outlining the federal-state government relationship. Section one states that all states will honour all of the other states laws; this ensures that a marriage in Florida is also considered marriage in Arizona. Similarly, section two guarantees that citizens of one state are treated fairly and equally like all citizens of other states. For example, it enshrines that a person fleeing a crime from a state with certain punishments, shall be returned by another state if necessary. Moreover, the 10th amendment in the Bill of Rights reserves powers to the states and to the people that aren’t in the federal governments’ domain. Essentially meaning, powers not mentioned in the constitution that don†™t deal with national issues are left for the states to decide on. A key example being policing and other local matters. British oppression had made the Founding Fathers fearful of unchecked centralized power. The Tenth Amendment was enacted to limit federal power. The sheer size of the U.S. means that states such as Alaska have different cultures and demands compared to California. As a result, governing the enormity from Washington would be very difficult. This is why states have their own legislatures with significant responsibilities such as education, healthcare and judiciary procedure. The states are funded in part by the federal government which allows states to allocate their funding for the pressing issues in their region, which might not be an issue in a state. This enables a more democratic process as citizens elect officials on a state basis who are more understanding of local issues and ideas whilst also electing a President and Congress to look after the general welfare and security of the United States. Federalism means that the central government lays claim to less powers and responsibi lities than it would do if it weren’t for the states. It could be argued that federalism adds another check and balance-the federal government may be rich in tax revenues but has little influence within America and plays a bigger role internationally than domestically. The constitution was drawn up in response to tyrannical rule by Britain; fearful of a strong, distant and central power ignorant of the people, fearful of this being repeated, Federalism was seen as the best  option. It was a compromise between self-governing autonomous states and a strong, overpowering central power. It meant at the time, that resources could be allocated accordingly to state demands whilst the federal government could unite forces in the event of an attempted invasion by a foreign power. ‘Transformed beyond recognition from the vision of the Founding Fathers’. Discuss this view of the modern US constitution. (45 marks) The US constitution has been the blueprint for countries around the world seeking to emulate a democratic system of governance. The constitution today still stands strong and is treated with the utmost respect by many Americans and its words are biblical to fundamentalists such as ‘Tea Party’ Republicans. The constitution was drawn up in wake of the tyrannical rule by the British Empire, over-taxed and underrepresented; the 13 colonies on the eastern coast were no longer content with the status quo and declared independence from their colonial rulers. Judging from the historical context, it is clear that the Founding Fathers wanted to prevent a situation similar to this ever arising again. This is why a constitution was drawn up compromising autonomous states and a strong central power which would oversee issues of national and international importance. Article 1 of the constitution established congress as the national legislature, giving it specific powers and responsibilities such as those to ‘coin money’ and ‘declare war’. It is slightly ironic that this so far specific article is also home to the most enigmatic aspect of the U.S. constitution; â€Å"provide for the common defence and general welfare of the United States’ and to make all â€Å"nec essary and proper laws†. The generalisation in these terms has led Article 1, Section 8 to be labelled as the ‘elastic clause’ of the Constitution. These terms don’t mention anything specific which has led them to be widely interpreted and argued over. The constitution has without doubt changed since its ratification in 1788, but because the Founding Fathers’ foresaw the necessity for change. They realised that it had to be designed to live and grow as the nation grows, which indeed it has and is evident in the fact that it is a global superpower and is home to the world’s currency reserve. Article 5 is a living testament to this as a sign that the Philadelphia convention delegates knew that it would have to change with the times. This article reserved the responsibility of amending the constitution to congress and the states’ providing both could deliver a  Ã¢â‚¬Ëœsuper majority’. Only 27 amendments to the constitution have ever been ratified (including the 10 in the Bill of Rights), demonstrating the religious nature of the constitution. Apart from the abolition of slavery, no subsequent amendments to the constitution have dramatically changed its nature. This demonstrates the almost religious nature of the constitution-changed so few times as to protect its power and standing in the governance of America. The constitution is living document, designed to be relevant for whatever period of time. However, despite this, the Bill of Rights, effectively apart of the constitution, is aimed at protecting citizens rights from a tyrannical government. But, recently, certain articles have been the source of controversy. A notable example being the 2nd amendment, the â€Å"right of the people to keep and bear arms† to enable citizens to defend themselves from an autocratic ruler. This is a source of national debate, events such as the Sandy Hook massacre have led gun control campaigners to demand laws passed to make the supply of guns much tougher. But, opposition in the form of Republicans, see it as a violation to the 2nd amendment. Unlike the rest of the constitution, this is an archaic clause, only suitable for the circumstances in which the constitution was written, and not in the 21st century when the threat of a foreign power invading/a violent government has gradually diminished. The Founding Fathers’ established the Bill of Rights to â€Å"sugar the constitutional pill† which gave an immense degree of power to the federal government and its branches. The 2nd amendment is not part of the elasticity of the constitution which sought to establish freedom and individual liberties. In fact, it could be argued that it detracts from the nature of freedom as citizens live their lives with the threat of gun violence whilst the constitution legalises it. This clearly wasn’t the intentions of the Founding Fathers’. The federal government over the last century has undertaken some of the responsibilities that traditionally belonged to the states. The changing federal-state relationship has primarily occurred under Democrat presidents, such as Franklin Roosevelt with the New Deal and President Obama with his economic stimulus package in 2009 and his flagship reform; ‘Obamacare’. Such packages stipulate that states commit to providing certain services and invest in specific infrastructure projects. Traditionally, the 10th amendment protected states autonomy but Democrats have used the elastic clause of  Article 1 to claim that they are providing for the â€Å"general welfare† of the United States. But, many Republicans argue that the federal government is encroaching state rights with its demands for road building, improvements to education and compulsory healthcare insurance from employers. Although the central governments demands have been legitimate and well intended, the federal two-tier relationship was designed for two different layers of government doing different roles. But, elasticity of the constitution has led to the tax-rich Washington based administrations take action in times of economic hardship. Federalism has had to be diminished for the national good, which in itself is approved of in the constitution. The main body of the constitution and the Bill of Rights conflict with each other as providing for the general welfare of the country and passing â€Å"necessary† laws may take away part of the state legislatures reason for being. The 1st amendment was established to guarantee the most basic and fundamental rights of religion; freedom of speech and freedom of press. Since the threat of terrorism has plagued western society, organisations such as the NSA and CIA have infringed on citizens rights to free speech by listening into private phone calls a nd the scanning of emails and social network accounts. Many argue that these federal agencies have long exploited the excuse of protecting national security whilst bearing the hallmarks of an overbearing government preventing its citizens from expressing themselves freely without fearing reprimand and insecurity in their everyday lives. The revelations of Edward Snowden have given us an insight into just how extensive government spying is. Again, the federal government has defended its actions by using the elasticity clause, stating that it is acting to protect the national welfare. But, it is clearly unacceptable for a self-proclaimed democratic country to be suspicious of its subjects in this manner. The Founding Fathers’ could have never foreseen this situation in which technology is used to â€Å"protect citizens†. But, since the system they established gives the government power to this, it can still carry on its extensive spying programs. Moreover, attempts have been made to make flag burning illegal under the constit ution. Flag burning is commonly used as a publicity stunt by Islamist extremists who feel that their religious beliefs conflict with American life. Banning of flag burning would prevent a specific section of American society from expressing their religious and personal views even if  they do sometimes condone terrorism. It is unclear, again, what the Founding Fathers’ views were on the 1st amendment. As the constitution is a living document designed to evolve with the times, it is the responsibility of the current generation of citizens to interpret it and act accordingly. Total freedom given to extremists expressing their opinion could lead to citizens fearing for their lives in the event of a terrorist attack. Like most aspects of the constitution, freedom in one area could undermine it in another. The 8th amendment strictly prohibits â€Å"cruel and unusual punishments†. This short and vague term has led many to believe that capital punishment should be abolished as it takes citizens lives. Some activists in favour of capital punishment believe that the 8th amendment technically allows for it to exist, many claim that the punishment in the form of lethal injection is not â€Å"cruel† because as opposed to other methods such as death by firing squad or electric chair, the convicted feels very little pain and dies in a more humane circumstance than the latter two options. The Supreme Court has never declared capital punishment as ‘unconstitutional’, despite many unsuccessful reviews. It is perfectly legitimate for some forms of the death penalty to be considered humane and not cruel within reason. The Founding Fathers’ established a broad framework for subsequent generations to alter as necessary. No matter, capital punishment seems anomalous for a country whose constitution stipulates the prohibition of cruel and unusual punishments. Like with many other constitutional arguments, the historical context must be taken into account. At the time, the 13 colonies wanted to create a civilised and stable society. In conclusion, the constitution has evolved simultaneously with the United States. The country that the Founding Fathers’ created has expanded and transformed beyond recognition through time. Therefore, it is legitimate for the constitution to mirror this. Except, it hasn’t. The constitution still stands in its exact form as it did upon creation, excluding the Bill of Rights which was an addition also enacted by the Founding Fathers’, only 17 amendments have been passed. None of which have directly affected the nature of the historical document. Although the constitution might have stayed the same, the arguments and its purposes have developed dramatica lly. Both left and right, citizens respect the constitution and try to exploit its hollow meaning clauses for their own policies. It is treated reverently and still serves its purpose today;  ensuring accountability at every level of government. Perhaps it is too rigid in some aspects by granting the â€Å"power of the purse† to a partisan Congress and nearly allowing America to default on its debts. Their vision will still be upheld so long as the Supreme Court continues to function as the umpire of constitutional debates.

Essay Writing Advice Structure It Up!

Essay Writing Advice Structure It Up! Essay Writing Advice: Structure It Up! If you are looking for essay writing advice, look no further. Writing an essay requires that you include the basic elements of a five paragraph essay. Even if your writing task is a bit more involved, the same elements must be included. Introduction When you are writing your introduction you want to pay attention to the exact word choice you have. This is your first and, in some cases, your last opportunity to leave a positive impression on your reader. This is not only where you talk about your subject for the first time, but where you also explain to the reader how you are going to talk about your subject. You should be putting a higher level of energy into your introductory area, totaling about 20% of your overall writing efforts. And if you do this you will be rewarded positively. Body Paragraphs The second step is a body paragraph where you need to present your 1st strongest argument or your best illustration or example. Much like the previous section of your writing assignment, the first sentence needs to have a hook which naturally transitions from the hook located at the end of the previous paragraph. The subject of this paragraph or the main idea needs to be presented in the topic sentence immediately after. You want to make sure that you relate the main idea here to your thesis statement much the same as you did in the previous section. And finally, once you have done this you need to include your transitional hook in order to help the reader move along once again to the 2nd body paragraph. The 2nd body paragraph is where your weaker argument is located and it should be followed after the transitional hook with your topic sentence. Once again the evidence and support that you present need to relate back to your thesis statement. Never assume that the reader will know what you intend to say or will be able to pick up on what you are hinting at. Instead, make sure that you state your purpose explicitly. Once this is done you need to end. With a transitional hook which signals that your final point has been made and that they will now reach the end of your document. Conclusion The conclusion is the end of your writing but it does not serve as an afterthought. The final paragraph is the final opportunity you have to restate your case and it needs to be very rigid in its format. You want to try and paradoxically think of the conclusion as the second introduction because it will contain many of its features. You want each sentence to be well-crafted and you want to make sure you have an effective concluding transition after which you restate your thesis. Remember, the best essay writing advice revolves around laying out each component of the traditional writing tasks, including introductions, body texts, and conclusions. These make up the basic structure of your work. By incorporating all of these components, you can enjoy a well put together essay.

Tobacco Companies and Product Safety Essay Example | Topics and Well Written Essays - 2500 words

Tobacco Companies and Product Safety - Essay Example The unethical activities by a firm appear in different forms and nature (Curwen and Whalley, 2005). In this report, analysis of one such case will be carried out. Hence, a brief overview of the case chosen for this study is detailed below. The case entails about the significance of product safety and the role played by companies in managing these safety standards. The case highlights a real life incident of 2004 where the US district court ruled eminent tobacco manufacturing and marketing companies such as Liggett, Philip Morris and Reynolds to pay a hefty fine of $ 280 billion if the US Department of Justice (DOJ) proves that these companies are continually deceiving the customers despite knowing the risks of smoking and its addictive nature. The case also highlighted about the fact that tobacco manufacturing companies have formed a committee so as to carry out research and developmental works on the adverse effects of Tobacco. However, the committee deceived people by denying the f act that smoking causes cancer or any other type of health effects. Ironically, research carried out by other researchers clearly showcased that smoking did causes cancer. Furthermore, the case also made it evident that Tobacco companies advertised that nicotine is not an addictive material and even campaigned to target teenagers. One of the key findings from the case was that tobacco is a product that kills around 400,000 American people in a calendar year. Regarding this matter, DOJ claimed that it is the duty of the firms to design a safe product and at the same time test its quality before launching in the market. Even these companies have also intentionally not warned the customers about the ill effects of nicotine consumption. Hence, the case makes it evident that it is a sheer violation of the ethical norms and morality of business for such kind of finds is a subject of question. This report seeks to investigate the ethical and moral issues associated with the selling of good s in the market and along with that moral and ethical issues will also be highlighted. The duty of a company towards its customer is another vital area which will be covered during the course of the study. In addition, theories and literature pertaining to this area will be highlighted in the study in order to strengthen and justify the claims made in the study. The study will begin with a brief summary of the duties that a company has towards its consumers. Duties to Consumer Ethics have been defined as one branch of philosophy that deals with the systematization and recommendations related to the conception of right or wrong. It helps in addressing to the issues that are arising in moral diversity. Now the question arises that what is morality. Morality can be described as a systematic procedure that helps to differentiate between what is right and what is wrong. Moral theories provide exact framework for analysing, discussing and finally evaluating all the moral disputes in very reasoned manner. As mentioned earlier, it is the emergence of globalization which has lead to increase of the need of business ethics. Generally an organization has three main goals: One being incur of high profits, the second being responsible environmentally and the third one being responsible socially. In order to attain such goals, it is significant that the organizations perform certain responsibilities

A Perky Way to Productivity Case Study Example | Topics and Well Written Essays - 750 words - 1

A Perky Way to Productivity - Case Study Example Having such an organized work setup gives rise to a culture in the organization that has a great impact on the psychology of the organizational personnel. The importance of employee benefits as a strategic component of fulfilling the goals of human resource management in either of the two companies cannot be overemphasized since employee benefits play a fundamental role in increasing employees’ satisfaction and keeping them motivated to use their optimal potential in the work. Achievement of the workers’ satisfaction is a pre-requisite for the obtainment of the strategic goals of Genentech and Zappos. By providing their employees with benefits, both companies generate this message to their workers that they do not just care for their workers, but they actually possess them. Especially when the benefits extend to include the families of the employees, it creates a dual-action on the employees to keep working in the same company in which, the company’s management a nd the family are the two motivating entities for the employees. Employee retention enables the companies to achieve their strategic goals since every employee that has worked with a company for some while understands the company’s culture and objectives, and the skills of the employee have been customized to the individualistic needs of the company, which is what makes the employee special for the company and a means of attaining its strategic goals. 2. Genentech and Zappos use employee benefits as a motivating tool in a variety of ways. They provide their respective employees with a wide array of benefits that include but are not limited to rewards for longevity, increments, bonuses, provision of free meals both to the workers and their families, free child care, and frequent leaves and vacations. Both companies have a strong organizational culture that places huge emphasis on equality among workers and easy flow of communication across all channels.

Advantages And Disadvantages Of Hybrid Cars Engineering Essay

Advantages And Disadvantages Of Hybrid Cars Engineering Essay Even by recently introducing hybrid vehicles to the worldwide transportation system, the need to reduce transport generated CO2 emissions is still a matter of high significance. One promising and at the same time environmentally friendly solution in terms of limiting the greenhouse gas (GHG) emissions is considered to be the introduction of hybrid electric vehicles (HEVs). In this technical report HEVs will be compared to conventional internal combustion engine vehicles (ICEs) and battery electric vehicles (BEVs), by surveying their technical characteristics and performance, their total cost of ownership (TOC) and their GHG and air pollution (AP) emissions. HEVs can be classified either as parallel or series due to differences at their powertrain configuration. They both use an electric motor and an engine but only parallel HEVs can use simultaneously either of them as a main power source. At series HEVs the engine charges an on-board battery unit that transmits power to the electri c motor. Reduced engine capacity, regenerative braking ability and engine shut-off capability are the main discernible characteristics of HEVs in confrontation to their equivalent conventional models.1Some of the most generally acceptable advantages of the HEVs are their low local emissions combined with a high fuel economy, the long driving range and their commercial availability but they still depended on fossil fuels and they are more expensive than conventional ICEs.2 Technical characteristics and performance Vehicle efficiency and primary energy efficiency, or otherwise well-to-wheel efficiency are the measures used in this study to compare those different drivetrain vehicles. We define the Vehicle efficiency: and, the Primary efficiency where = the useful energy at the wheels, = the energy supplied to the vehicle and = the primary energy.3 Hybrid Electric Vehicle (HEV): For both parallel and series HEVs the vehicle efficiency is 29%. Internal Combustion Engine Vehicle (ICEV): The max efficiency ay ICEs is achieved near the max load point. The mean efficiency is relatively low since no max power can be achieved in normal driving conditions. At mean required power of 10kW the efficiency is low around 18% whereas around 60-90kW reaches up to 35-40%.4 Battery Electric Vehicles (BEV): An electric motor, connected with a generator and a system of transmission forms the main function of BEVs. Due to the development of advanced electronic control systems, the mean energy efficiency over a normal drive schedule has increased both for generators and electric motors.5 The potential vehicle efficiency is 61%. The difference in efficiency between hybrid and conventional vehicles can be partly justified by the use of Atkinson-cycle in the hybrid vehicle engines instead of the Otto cycle in the ICEs.6 In cases where the Atkinson cycle is applied to a well modified Otto cycle engine it results to high fuel economy that can be explained by the lower per displacement power than the traditional ICE four stroke engine. When more power is needed, an electric motor can supplement the engine power which is the basis of an Atkinson cycle working hybrid-electric drivetrain. Bigger work output and higher thermal efficiency than the Otto cycle while operating under similar conditions leads to higher primary efficiency in HEVs.7 In terms of acceleration, BEVs are better than both HEVs and ICEs but in high speed performances ICEs are faster than HEVs with BEVs to be the slowest.8 Total Cost of Ownership The total cost of ownership is by estimation the sum of the purchase price (Components, retail margin, battery, initial on-road costs), the operating costs (fuel, electricity, servicing) and the resale value. The purchase price is fixed for each vehicle (excluding the uncertainties in the battery prices) but in order to define the operational cost we first have to settle a representative drive cycle. In this study we will work with the AUDC (Australian Urban Drive Cycle) which is a bit more intense in the driving behavior than the common ones but still close to the NEDC (new European drive cycle) and the ARTEMIS cycle (150000 km travelled per vehicle lifetime) .9,10 Due to the large uncertainty in the vehicle battery prices we took a baseline value of $800(kWh)-1 or $16.800 [brooker,4] Furthermore, we estimated a base fuel price at $1.4 L-1 as well as a base electricity price at $0.175 kWh-1.11 In order to determine the operational cost of each vehicle we need to define the fuel and electricity consumption of our modeling vehicles. For a Class E parallel HEV the fuel consumption in L/km was calculated 5.7 whereas for the same category the CV had a consumption of 9.4 L/km. The electricity consumption of a Class E BEV is 0.11 kWh/km. It is clear that despite the entailed increase in vehicle electrification in the purchase price it is compensated with a decrease in the operational costs. Only by comparing each vehicles purchase price, the CV is the most cost effective solution of both HEVs and BEVs with the lasts to be the most costly ones mainly because of the high battery costs. On the other hand even though the BEVs have the lower running costs it is shown that the parallel HEVs are the ones with the lower Net Present value. Finally in a recent study it was suggested that even hybrid cars are a quite more expensive than the conventional ICE vehicles thay may reduce fuel consumption by 34-47% compared to them which decreases their NPV even more.12 Environmental evaluation In order to determine the environmental impact of each vehicle we will examine their air pollution and greenhouse gas emissions. To estimate the total CO2 emissions we use the product of carbon intensity (CO2e/MJ) by fuel producers, energy intensity (MJ/km) by car producers and demand (km) by car drivers. In Hybrid (gasoline) vehicles the CO2 emissions are 20 gCO2/MJ and 220 gCO2/MJ delivered to vehicle wheels during production and vehicle life cycle respectively. In ICEs the emissions during production and life cycle are 50 gCO2/MJ and 300 gCO2/MJ whereas in BEVs (electricity production from coal) are 320 gCO2/MJ and approximately 0 gCO2/MJ respectively. It is interesting to notify that in case were electricity production comes from renewable sources (wind) the emission at the production stage of BEV are almost defeasance.13,14 Table1 Environmental impact associated with vehicle production stages Type of car GHG emissions (kg) AP emissions (kg) Conventional 3595.8 8.74 Hybrid 4156.7 10.10 Electric 9832.4 15.09 In both HEVs and BEVs we must also consider the environmental impact of batteries. We assume that both vehicles use NiMeH batteries of 53kg (1,8kWh capacity) and 430kg( 27kWh capacity), respectively. The production of those batteries require 1.96MJ of electricity and 8.35MJ of liquid petroleum gas.15 With those data and considering that the number of batteries per life of vehicle is 2 for hybrids and 3 for electrics, the total GHG emission per life of vehicle are more than 12 times higher in BEVs. Finally in order to compare the total GHG and AP emissions for ICE, BEV and HEVs we will consider the scenario that electricity is produced only from renewable energy sources. In that case ICE vehicles are the most polluting ones with almost double GHG and AP emissions than hybrid vehicles and 10 times more than BEV vehicles (450/235/40 g CO2,equivalent /mile respectively).16 Table2 Total environmental impact for different vehicles Car Type GHG emissions(kg) /100 km of travelling AP emissions(kg) /100 km of travelling Conventional ICE 21.4 0.0600 Hybrid HEV 13.3 0.0370 Electric BEV 2.31 0.00756 The average travelling distance during a 10 year vehicle life time is 241,350km.17 We must say here that in any scenario for electricity production the BEV are still the most environmentally friendly vehicles. Furthermore, hybrid cars may reduce Well-to-wheel GHG emissions to 89-103 gCO2 comparing to conventional ICE gasoline vehicles.18 Georgios Fontaras, Panayotis Pistikopoulos, Zissis Samaras, 2008, Experimental evaluation of hybrid vehicle fuel economy and pollutant emissions over real-world simulation driving cycles, Atmospheric Environment 42, 2008, 4023-4035.

Construction resources Essay

Construction resources make use of physics in many of their products. Two that I have picked are solar collectors and their use of insutation. Insulators have the purpose of preventing conduction, convection and radiation to unwanted areas. There are a wide range of techniques and materials used in doing this and I am going to look in depth at this idea. The company uses solar collectors in many different ways, their main purpose is to collect solar energy and heat energy. They can be used to heat and power many different appliances. Photovoltaic cells: Photovoltaic cells transfer the energy carried by the electromagnetic waves that make up sunlight directly to an electrical circuit in order to make a current flow. Light excites electrons to move from one layer to another through semi conductive silicon materials. Only a fraction of a volt is produced so a large array is needed to produce appreciable currents, usually about 20W to 100W. The Photovoltaic cells produce DC current so if alternate current AC is desired then an inverter is required. AC form is commonly available from the mains. Solar cells: Sunlight may also be used to heat water directly. This can be done in two ways, water can be circulated through pipes which run through the back of the solar cells, producing water at around 60oC suitable for household use. The other method is to focus sunlight from a large are to a small spot using an array of mirrors, this can produce temperatures of up to 4000oC and it’s quite feasible to produce power stations from this, however it has not been implemented yet. Here is on way in which the hot water can be used, this is quite economical and environmentally friendly. Solar panels are quite versatile and can be put on many roofs of simply in the garden, which makes them popular when it comes to heating swimming pools of hot water for showers. Any material that is a poor conductor of heat and electricity can be used as an insulator. Thermal insulating materials reduce the flow of heat between hot and cold regions. Thermal insulation may have to fulfill one or more of three functions: to reduce thermal conduction in the material, in which heat is transferred by electrons; to reduce thermal convection currents, which can be set up in air- or liquid-filled spaces; and to reduce radiation heat transfer, in which thermal energy is transported by electromagnetic waves. These are three ways in which heat energy can be transferred. Conduction, where heat energy is transferred through solid materials, metals are normally the best conductors. There are a number of factors that affect thermal conductivity. Increasing the area of the cross-section of the solid through which hear flows increases the rate of flow, however increasing the thickness of the wall decreases the flow of heat. Provided that a steady state has been reached (where the temperature of any point is not changing through time) then the rate of flow of heat ? Q/? t is given by: ?Q/? t –> A ? T/? x Besides the physical dimensions of the materials, another factor affecting rate of flow is the properties of the material, the Thermal Conductivity of the materials ? through which the heat energy is travelling is the constant of proportionality in this relationship, so:?Q/? t = -? A ? T/? x The units for thermal conductivity are watts per metre per kelvin. The Quantity ? Q/? t is called the temperature gradient. On my visit to Construction resources I noticed that they have used these Physical conclusions in there insulation. One in particular is ‘Homatherm’ a wall and roof insulator. The slabs are thick which means less flow of heat, and have a thermal conductivity is only 0. 04 W/mK. Conduction in terms of particles: The particles in metals and non-metals are arranged differently, which gives them their different characteristics. In a non-metal the particles have forces between them that can be described like springs. When heat is delivered to the solid the oscillations of the particles being heated will increase in amplitude. For heat to be conducted the neighboring particles must also receive the extra energy, as particles oscillations increase in frequency the neighboring particles also gradually increase in frequency as heat is transferred to them. This is a very slow process. In a metal the arrangement is different, metallic boding occurs between metal atoms where a ‘sea of delocalized’ electrons hold the positive metal ions together in a lattice. It is these free electrons that are responsible for the high conductivity character of metals. When a metal is heated the metals ions vibrate with an increase frequency. When an electron hits these ions with extra energy, they receive this extra energy and move faster. This electron can then travel to another parts of the lattice, to an ion that hasn’t received any of this heat energy and collide with it, transferring its energy to this ion. Now that ion has extra energy and vibrates with a greater frequency. This process is a lot faster as there are many electrons in a metal lattice. U-Values: Architects and heating engineers use U-Values to calculate the flow of heat energy through building materials. The U-Values is quoted for a given thickness of a particular material, and is based on actual measurements made using the material. The U-Value is defined as: U-value = Rate of energy flow Area X Temperature difference Construction resources uses this knowledge of U-Values when designing building materials to reduce the energy wasted in the form of heat going out of the build and to achieve the ultimate goal of reducing CO2 emissions. But there are obvious limitations with reducing thermal conductivity, you can only reduce it to a certain amount, 0. 025 in air, so there will always be heat loss. Also too much insulation in the house will lead to what construction resources refers to as internal pollution. This has lead to construction resources researching in trying to lower the energy that is used to build and transport he construction materials. Bibliography: Microsoft Encarta Heinemann Advanced Science Salter’s Horner’s AS Advanced Physics Strengths and Limitations of Photovoltaic cells: Since one photovoltaic cell only produces a small fraction of a volt, large arrays are required to produce appreciable voltages. This requires a lot of space and the cells need to be in a place where no shadows will be cast on them. This limits what they can be used for. Also the amount of power produced by the photovoltaic cells directly depends on the amount of sunlight, so they cannot be relied on to produce power for something that constantly needs it. The only way this can be overcome is if some power was stored for a rainy day. But this again would take up space. Also an array of solar collector will be expensive and have a long ‘pay back’ time. However it is environmentally friendly and after the pay back time, savings can be made. Also photovoltaic cells can be made look attractive depending on where they are placed. Strengths and Limitations of solar cells: The solar cells have similar limitations to the photovoltaic cells in regards to positioning and cost but a small array is only required to produce enough hot water for something like residential showers or central heating. This is economical and environmentally friendly and solar cells are quite versatile.

How Will Science and Technology Change Our Lives Essay

The Contribution of India to the world of Science & Technology dates back to ancient times. India had the best of the scientists in different fields of science and technology – mathematics, medicine, architecture, astronomy, geometry, chemistry, metallurgy, etc. Aryabhatta was a fifth century mathematician, astronomer, astrologer and physicist. He introduced the concept and symbol for Zero and the decimal place value system to the world of mathematics. Bhaskaracharya introduced Chakrawat Method or the Cyclic Method to solve algebraic equations. Kanad, a sixth century scientist developed the atomic theory which says that the material universe is made up of anu/atom, which cannot be further subdivided and they are indivisible and indestructible. This is what the modern atomic theory says. In the field of medicine, India was a front runner. Susruta was a pioneer in the field of surgery. Charak, considered the father of ancient Indian science of medicine, was the first to talk about digestion, metabolism and immunity as important for health and so medical science. The science of Yoga was developed in ancient India as an allied science of Ayurveda for healing without medicine. India was a pioneer in many technologies such as metallurgy (steel making, iron, zinc, bronze etc) and Architecture. The findings in Moganjatharo civilisation stand testimony to this fact. The structures such as Iron Pillar in Delhi, Taj Mahal, Gol Gumbaz, Mahabalipuram, Tanjore Periya Kovil are some examples of India’s supremacy in the Architecture. Science and Modern India Indian scientists have played a stellar role in the development of India. In the short span of its post-independence history India has achieved several great scientific achievements. Indian scientists have proved their mettle in the face of international sanctions and have made India one of the scientific powerhouses of the world. Sir M. Visvesvaraya, Sir CV Raman, Jagadish Chandra Bose, Subramaniam Chandrasekar, Srinivasa Ramanujam, Homi Bhaba, Vikram Sarabhai are some of the names leading the pack of Indian scientists. How technology impacts people’s life? Technology affects people’s lives by improving medicines, provides better treatment for diseases and insures a longer life. It improves transportation by helping people move from one corner of the world to other in hours by using transportation services such as Airways, Railways, or even Bus Transportation. Modern Technology changed people’s lifestyle and the way they live. For example, now it’s possible to surf Internet on TV, watch programs, pause Live TV, and even playback live shows. Internet surfing is a technology revolution. Because of that technology, a person could know what is happening on the other side of the world. Due to Internet, it is now possible to say that the world is at your fingertips. Recent discoveries and scientific breakthroughs such as Cracking the DNA code and Mapping the Genome may completely change the way people look even before they are born. Diseases that are passed through generations, like diabetes, chronic diseases may be eliminated from the unborn child. What India should do? While India is uniquely positioned to use technology for progress, it has in the recent past lagged behind in the quality and spread of science research. The need for a strong science eco-system based on a sound research foundation is the need of the hour for India to become a Global Power house. The key to continued success for India in a globalised knowledge-driven economy is building a higher education system that is superior in quality and committed encouragement of relevant research in science and technology. To achieve this, the government, universities, companies, venture capitalists, and other stakeholders should come together to enable Research and Development to achieve superiority in the field of science and technology.
