Hysteria Comparison of the Salem Witch Trials and the...

Andria Garza 11/30/12 English Final Draft Hysteria comparison of the Salem Witch Trials and the Holocaust During both the devastating Holocaust in the Germany and the tragic Salem Witch Trials in the small town of Salem, innocent people were brutally killed, causing hysteria among the people. Both groups of people endured hardships because of the hysteria that occurred among them. This hysteria caused people to react in ways that they would not usually act. Both of these events are very historical and help The United States of America be a unified and prosperous country that it has grown to become today. Hysteria is defined as an uncontrollable outburst of emotion or fear, often characterized by irrationality, laughter, weeping†¦show more content†¦The elderly people in the holocaust had no say so in anything and often they were looked at as a complete waste of space. According the Nazis, the vicious soldiers who ran these brutal camps, the elderly people could easily be killed so that they could make room inside of the often over crowded work camps. Poor people were also were frowned upon during the Salem Witch Trials. Many of the people, who had money and were well off, thought of them as scum. In a lot of cases there are people that tend to think that because someone does not have money they cannot make logical choice or decision. In the Holocaust many people that were poor were imprisoned. These people were not considered important. They were often considered to be the lowest of the low. During both of these events it is sad that just because someone is old or someone that lacks money could be treated as any less of a person that was younger or had money. There were deep rooted issues in both Germany and Salem that led to these dysfunctional occurrences that caused a mass hysteria among the people. Unity was the key factor that lacked among the people in the town Salem and the country Germany. Although Germany was united patriotically they were not united religiously. In Salem the people lacked a religious unity. They were not confident in their faith in God. If they were strong in their faith they would have had some sort of conscience and feel badShow MoreRelatedThe Human Lust For Power By Arthur Miller1689 Words   |  7 Pageshighlights a different facet of power: the means by which individuals strive to obtain it.

Family Origin Paper - 1821 Words

Trever Sorenson Valerie Wall Individual, Family, and Society October 29, 2012 Family of Origin Paper To start my family origin paper we have to go way back to 1976 when my parents met in Alamo, North Dakota; a town of about 200 people in the northwestern part of the state. They met while going through school playing sports, mainly basketball. Both were pretty good at the sport and won some awards and had chances to play more but decided to get married and start a family instead. Both grew up around the whole farming scene. My mom actually lived on a farm growing up and also as she started her own family. My dad lived in the small town but his grandpa had a farm not far from where he grew up and also helped a lot of the local†¦show more content†¦My dad would wake us up at six in the morning and we would drive all the way to town for school at eight. My brothers and I did not want to attend country school because when we lived in town those first couple of years we had made some friends and our parents wanted us to have a healthy social life. I think also they wanted us to participate in sports more, which we did. Growing up it seemed that every night we had to stay in town until at least 8 because one of us had a sport practice or game going on. So I think that the competitiveness in sports that my parents faced growing up they wanted my brothers and I to experience that. My brothers and I loved to play sports, a lot of the time when we were not helping my dad we would be playing some sort of competitive sport which usually ended in a fight. Once we moved farther into the country my brothers and me became older and more capable of helping my dad on the farm with chores. So it was in these early years where were learn a work ethic. With having all the cows we did my dad did need help. For me being the youngest I didn’t have to help as much as my brothers. I spent more time helping my mom around the house with things she needed help with. But my dad always made sure I got my hands dirty in the corrals, whi ch I can see helped me with just being able to do manual labor with no problems, and also made me a very observant learner from watching my dad do thingsShow MoreRelatedRole Of Homeobox Geness1022 Words   |  5 Pagesof conserved genes that belong to the homeobox family.

Once You Open Your Eyes free essay sample

When a human being is a victim, they need to have courage and follow their ways, no matter what others say. Jem and Scout see people become victims of prejudice, rumors, poverty, and other atrocities in their own little town, as they grew older. In To Kill a Mockingbird, the children learn life lessons from witnessing people striving to survive different situations within Maycomb. When a challenge causes one to struggle, the children see that person, or themselves, have to have courage to do as they have before. Jem and Scout see their small town judge the Radleys, but the Radleys still do what they have done for as long as any single person can remember. They never talk to their neighbors or open their doors and windows on Sunday. Since they have odd habits, from other’s perspectives, and keep to themselves, citizens of Maycomb start rumors about them, saying â€Å"Radley pecans [will] kill you† (Lee 9). These rumors criticized the Radleys and made people afraid of them. Calpunia had something to say about them, stating one day that Mr. Radley was â€Å"the meanest man God ever blew breath into† (Lee 12). Since he was â€Å"mean,† that held more rumors to be made about them. The stories make children believe Boo was locked up in a damp basement in the courthouse for years and is now chained up in his house. The Radleys stay the way they are; despite the rumors, remaining removed from human contact. The Radleys are victims of misunderstanding and people’s cruel stories â€Å"unwilling to discard their initial suspicions† (Lee 9). Jem and Scout witness the Radleys to stick to their ways since they go against the crowd, despite society’s wants. The Finch children begin to notice many children’s families are victims of poverty, especially the Cunninghams, but the Cunninghams are different; they never take charity or have to depend on others. The Cunninghams are one of the poorest families in Maycomb, but they have the strongest determination to survive; and are the hardest workers. They have a great deal of pride and are respectable people. â€Å"‘The Cunninghams never [take] anything from anybody, they get along with what they have,’ † states Scout (Lee 20). Walter Cunningham would not even take a quarter of a dollar to buy a lunch because of how he was raised. The Finch children realize the Cunninghams are a brave family to live under their circumstances and not accept anyone else’s charity. If one does not accept others’ charity, they suffer more and do not always know when they are receiving their next paycheck. It is scary to not know these things, but the Cunninghams are proud and brave when to not accept the offerings of other people. The Finch children understand this from listening to Atticus talk about the Cunningham family. Tom Robinson suffered because of people and their prejudice beliefs. He also suffers from others misdeeds and died as innocent as a mockingbird. Jem becomes a victim when Tom Robinson was found guilty. He realizes the court does not always work. Jem became a victim of the system’s flaws and shortcomings. He used to believe that the court always worked, but learned it did not, when a jury found a clearly innocent man guilty. This crushed him, but it made him grow up and learn to accept things like this, because when maturing, one has to realize the world isn’t perfect. He had to have courage to accept this factor in life. It is a atrocious crime to take a persons life to merely keep the truth in the shadows; but with the pain of Tom’s death blooms a new hope of equality for the town of Maycomb, with just a baby step. Like all other children, Scout and Jem have to face all the challenges of growing up, but they have to keep going on with their lives, no matter what problems arise for them. Scout experiences the challenges of growing up when her aunt moved in. She criticized Scout for wearing pants and not acting in a lady-like manner, but that was only a small problem, and Scout stayed herself. She kept wearing pants and speaking her mind because she wanted to be an individual. Scout is surprised by prejudice, while going up. She was not aware that prejudice existed. She witnesses others victimize each other because they are different, either because of their color, friends, how they act, or many other reasons. She learns and sees this happen when listening to neighbors gossip about the Radleys, her teacher bad-mouth African Americans, or even her own self be criticized by the way she speaks her mind. Scout does not understand why people are like this, putting labels on certain types of people, like African Americans, saying â€Å"all Negroes lie, that all Negroes are basically immoral beings, that all Negro men are not to be trusted around our women† (Lee 204). Scout knows that not all people are perfect. She has to accept that some humans do not always treat others with kindness. Both Jem and Scout have to be brave and deal with the changes in the world. Scout and Jem learn from people, or themselves, when they are victims of different situations, but they are still brave. Atticus points out that real courage is when someone goes through life, still fighting, even if they are victims of prejudice, rumors, lies, hate, misunderstanding, or life’s shortcomings; to not give up even if you’ve already lost . Jem and Scout learn to keep their ways, adjust, and not judge people without knowing the full truth about them. They hope for the world to be a more understanding place.

Sick Around the World by Frontline Essay Example

Sick Around the World by Frontline Essay The documentary film Sick Around The World deals with the topic of healthcare systems across the world. In the film, five capitalist democratic countries are chosen for analysis. The rest of this essay will briefly describe these, scrutinize their pros and cons and identify the best among the lot. The essay finally attempts to find ‘the best’ system’s suitability to the United States economy and the possible consequences in the event of being applied. In terms of ‘cost to patient’, the United Kingdom’s healthcare system is the undisputed leader in the world. The government acts in twin roles of 1.healthcare provider and 2.patient insurer. The government gathers funds for healthcare costs beforehand through an ingenuous method of taxation. Of course, as could be expected with a â€Å"socialized medicine† model, there are the usual bureaucratic hassles. But apart from that, the UK healthcare system boasts an enviable record of health management and impressive patient outcomes. The National Health Service (NHS) is the central government agency that takes care of all aspects of catering to citizens’ health. The film then goes on to show the workings of the healthcare system of Japan. Here, the system is slightly different, in that, it is a â€Å"social insurance† system, wherein the costs are distributed between the employers, non-profit community organizations and citizens. While insurance com panies and hospitals in Japan are predominantly in the private sector, they are very well regulated. In this system, monthly premiums cost only $280 for an entire family.

Those who cannot afford to pay their premiums get covered by taxpayer money. It is a sound system, where premiums are pegged to family incomes and the co-pay is often marginal. The only drawback of this single-payer-system is that it provides fewer choices for medical practitioners, whose monthly income is below par when compared to most European nations. The Swiss system comes closest to the American system in that the premiums are highly priced (about $750 per month per family). The system has generated better patient outcomes than in the United States. The other nation discussed in the film is Taiwan, which spends only 6.3 percent of its total GDP on public health. If one system among the five discussed above were to be picked, it would have to be the UK’s system. Firstly, a sizeable share (8.3%) of GDP is spent on the healthcare system without directly exposing the citizen to any of the costs. By a sophisticated taxation policy, the government bears the costs of running healthcare facilities, paying doctors and support staff and also procedural, medicinal expenses. The most impressive aspect of this model is its focus on preventative care, which would prove to be the perfect antidote for the ailing American healthcare system which holds the worst record for patient outcomes in the industrial world. Excepting for such features as Medicare and Mediclaim, the healthcare industry in the United States is privately run. Hence, a sudden transfer to the â€Å"socialized medicine† model is not only practically not feasible but also not prudent. An ideal solution would be the expansion of provisions within Social Security to cover basic he althcare needs. Such a move would also reduce administrative costs. While the American healthcare industry, including the hospitals, practitioners and insurers would take home paycheques for lesser amounts, the nation’s citizens belonging to all strata of society will be much healthier. Triggle,Nick. Soaring costs prompt rethink of long-term care planning, Nursing Management 19.10 (Mar 2013) 6-7. The article talks about how the public health budget in the UK has steadily grown over the years. It has now superceded military spending and consumers 8.2% of national GDP. But the bad news is that this trend is expected to continue in the future and could grow to 20% of GDP by 2061. Considering an ageing population and shortage of funding and resources the country is faced with a large crisis in the near future. In the article, some constructive suggestions were put forward by experienced healthcare professionals and policy makers. One important idea is to integrate social care and health care so that cost efficiencies are achieved. This is especially true for palliative, chronic or mental health issues. Another important idea is focussing on preventative health measures so that instances of hospitalization are reduced. .

In what ways did the British government attempt to hide the effects of the Blitz from the people of Britain Essays

In what ways did the British government attempt to hide the effects of the Blitz from the people of Britain Essays In what ways did the British government attempt to hide the effects of the Blitz from the people of Britain Essay In what ways did the British government attempt to hide the effects of the Blitz from the people of Britain Essay When war broke out in 1939, there was an air of reluctance among the British people. The horror of the First World War was fresh in peoples minds and many did not want to experience that again. The government recognised the need to keep up morale, because if it were destroyed then the war would be lost, and designated a department, the Ministry of Information, for the production of propaganda and the organisation of censorship. When the Blitz started in 1940, the government thought it especially important to safeguard the public spirit due to the damaging effects of civilian bombings, both physical and psychological. They used a variety of tools to accomplish this, such as radio broadcasts, newsreels, and poster campaigns. However, it was not a simple matter of hiding information from the public. Some things were censored, but it was more about presenting a carefully crafted image to people and using scenes of destruction to convey positive, morale-boosting messages. One of the ways in which the British government attempted to control public opinion was through the use of propaganda. Multiple poster campaigns were commissioned and Ministry of Information newsreels were watched by thousands every week. Radio broadcasts, listened to by a large proportion of the country, were also heavily influenced by the government. The only radio station available was owned by the BBC, which was in constant communication with the Ministry of Information about how events should be reported. Even light entertainment on the radio often contained an underlying message. Censorship was also carried out. Journalists had to submit articles for checking and some newspapers which breached these regulations were officially banned. Several pictures and clips of film footage deemed not suitable for public viewing, such as a film of a mass burial following raids on Coventry, were concealed and not unearthed until after the war. The government felt a need to censor images which were particularly distressing or which showed the country not coping well with disaster. A photograph of the bombed playground of Catford Girls School is an example of an image that was not shown to the public. Dead bodies in bags are seen strewn all over the ground. Photographs of this nature were unlikely to have been approved for publication because actual, rather than implied, death is clearly shown. This might have disturbed people, especially those who had not had a personal experience of sufferings of this magnitude. Actually to see a picture of the dead bodies of children just casually lying around is far more depressing than an impersonal, relatively meaningless list of casualty figures. Also, the viewing of images showing despair or intense grief was restricted. The government wanted to put across the message that Britain was coping well and pulling together; being psychologically unaffected. Film clips such as one of a bereaved woman overcome with grief after a funeral would not corroborate this and so were banned. However, many scenes of physical destruction were not censored, but used as pieces of propaganda. This was so that the people of Britain could be shown rising above the devastation around them and emerging as a united, confident, glorious nation. The film Neighbours Under Fire shows many newly-made homeless people who are singing, laughing and apparently pulling together as a community. This courage is made more startling by the repeated shots of the completely wrecked buildings around them. Their homes and belongings may have been destroyed, as we are constantly reminded, but their spirit has not. This use of propaganda was not directly hiding the effects of the Blitz but rather slightly misrepresenting the psychological and social ramifications. We see a country whose spirit is completely unaffected by the hardship; which is becoming a stronger nation because of it. There is no mention of the terrified residents of Coventry trekking out every night and sleeping in the fields or the vast, fearful crowds gathering to force the government to open the Tube stations as shelters. Also, if the message of the propaganda had been that Britain was barely affected at all then the anger of the people who knew otherwise would have been aroused and little notice would have been taken of the material. The films were made more plausible by the showing of some measure of destruction and this actually helped to disguise the real situation because people would have seen little reason to question the image of unity and perseverance conveyed. The British government tried to hide the effects of the Blitz by these means to preserve the morale of the people. They knew that a nation without patriotic resilience could not sustain the multi-faceted war effort at home and so through radio broadcasts, newsreels and poster campaigns sought to manage the public perception of and reaction to the Blitz.

Analyse Porphyrias lover by Robert Browning Essays

Analyse Porphyrias lover by Robert Browning Essays Analyse Porphyrias lover by Robert Browning Paper Analyse Porphyrias lover by Robert Browning Paper Essay Topic: Poetry The Secret Life Of Bees Porphyrias lover is one of the most dramatic monologues written by a Victorian poet. Many tried to grasp new concepts of sensuality and brutality but it was Browning who captured these themes perfectly. As the Victorian society developed its understanding on sexuality and morality, people realized how many problems they have to face due to the idea of bad and wrong. Consciousness was a new idea so many poets didnt look at the normal side of the society but tried to develop their understanding and reflection of the insane minds. Porphyrias lover is a great example of such a reflection. Through the monologue we are pushed to face the conflict within the mind, the most twisted endeavors of our souls and the tip of a huge mountain of insanity. The narrator of this great piece is a complex multi layered character who shows us the problems and conflicts within his mind. Browning unfolds the secrets of the narrator very subtlety. The murder is described with a passive and apathetic voice which makes this poem seem so unreal and abstract. The author touches the most delicate and dark sides of our mind and shows us what would happen if the was no conscious present or if it was understood differently. The narrator describes his actions as I found a thing, thing to do,( )and strangled her. This is a very passive description of a action. It tells us that the narrator believed it was a natural action; killing the girl. Her love was so dear to him, that he decided to keep it in her for eternity. This action could theoretically be considered romantic. However, isnt killing someone a brutal action. Here we are facing a great conflict. Were his actions romantic or rather brutal, is taking someone elses life a loving or a evil action? The narrator doesnt even see other possibilities. He is so satisfied with the love and compassion she is showing him ( happy and proud; at last I knew Porphyria worshiped me) On the other hand Browning tells us there was some questioning to his actions. No pain felt she, Im quite sure she felt no pain the narrator is reassuring himself that his actions were right and loving. This tells us that there was some rational thinking in his head. However, rational doesnt mean the same thing to everyone. There is no clear description of what is rational or not. If there is enough evidence to back up your action then it may as well be considered rational. The point is that the narrator does back up his actions with reasoning, unfortunately his reasoning and his action do not weigh each other out meaning that in our modern reality his mind is unbalanced and incorrect. To show the deep complexity of ones mind, Browning uses a very particular rhyme pattern through out the piece ABABB. The intensity and asymmetry of the pattern suggests the madness concealed within the speaker’s reasoned self-presentation. The speaker uses a few great metaphors. As a shut bud that holds a bee, I warily opened her lids. This could indicate the reflection upon his actions. As we know bees sting, the narrator doesnt want to feel the painful truth. A beautiful flower has died with his love hidden inside. It is now not visible so he opens her eyes again, afraid of what he might see; pain, horror, hate. Hes scared that once the bud id open his love will sting him and fly away. In the last line of the poem the author talks about the result of his actions, and yet God has not said a word. This tells us that the narrator knows his actions could be considered as bad but yet no one has done anything. No one stopped him from doing what he had done therefore it was right. This also indicated that our speaker is religious and is scared aware of heaven and hell, this could suggest that to hold Porphyrias love and passion was so dear to him it was worth more than being a good man or going to heaven.

Misuse of DNA Evidence in Homicide Cases Research Paper - 1

Misuse of DNA Evidence in Homicide Cases - Research Paper Example Several barriers exist that limit the contribution of DNA technology to homicide investigations. They include failure by law enforcement to effectively analyze DNA evidence, lack of appropriate communication between law enforcement and crime laboratory, insufficient resources that may not justify the use of DNA technology and use of incompatible DNA analysis systems. There are inherent problems with DNA technology that could lead to wrong convictions. These include cross-contamination, mislabeling of samples, and intentional planting of DNA and misinterpretation of test results. The government’s initiative to create DNA databases also violates privacy laws and therefore calling for the need for transparency on the use of personal information held in DNA laboratories. Given the challenges in the use of DNA evidence in homicide cases, it thus makes sense for prosecutors and investigators to work carefully, using accessible resources most competently. This will mean that DNA stud y should presently be carried out only when compulsory and required to establish an element of the crime. Primarily, it is for identification and also to prove presence or contact of a suspect at the scene of crime, when it is has been denied by the suspect (Butterfield, 1996). DNA is a fundamental building block of the genetic makeup of an individual. It is contained in almost every single cell of the entire human body and is unique to every human being including identical twins. DNA samples collected from the scene of crime can be used like a fingerprint to exclude or include a suspect in a given case. Since its discovery, DNA technology has proved to be a powerful tool in the provision of evidence to homicide investigators and other law enforcement agents. DNA can be found in a number of sources such as saliva, blood, hair, teeth, semen and bones. As early as 1980s, states began to enact laws that required the collection and analysis of DNA samples. In 1994, the
