Disaster and Emergency Management

The Philosopher Aristotle said that â€Å"the greatest virtues are those which are most useful to other persons† and former US President John Adams also said that â€Å"if we do not lay out ourselves in the service of mankind whom should we serve? † I believe that I have lived up to the sayings of a great thinker and a leader and nothing is more rewarding than to give my life to safeguard the security of Canada and my countrymen. After my Bachelors degree in Criminology in York University, I worked as a Signal Operator in the Canadian Forces Army Reserve Toronto Communication Regiment for seven years.As a Signal Operator, I have installed and operated satellite communication systems and digitized high-frequency in order to facilitate effective emergency communications during domestic emergency operations. The job also allowed me to manage local area networks (LANs) and local distribution networks, operate cryptographic equipment, generate key material, coordinate circui t restoration in communications and information networks, plan communications services, and perform in land operations.Due to my skills and abilities, I have managed three member mobile radio detachment units in various extreme weather conditions, taught new recruits on the use of communications equipment at the Canadian Forces School of Communication and Equipment and manage the safekeeping of top secret communications equipment. In the army, I am tasked to fight as infantry and use personal weapons, reconnaissance and section level tactics when the need arise.From November 5, 2007 to present, I have been working as a Border Service Officer to safeguard the security and protection of the Canadians from people who are entering the border. I have to assure my country that these people will not threaten their lives and no prohibited goods will pass through the border. All people and goods getting into Canada must comply with Canadian laws and regulations. In a fight against terrorism, I assist in combating money laundering activities, prohibit the entry of firearms and detain people who pose as threat to my country.To safeguard the health of our people, I have to be on guard against the introduction of human, animal and plant diseases as well as the flow of narcotics and other illegal and prohibited substances.

In August 2006, I completed my BS Criminology degree with Honours and I was placed on the Dean’s Honour Roll List as well as the Sessional AcademicAchievement list at York University.With my academic achievement, knowledge and skills, I am confident that I would make an excellent addition to the graduate program in Disaster and Emergency Management at York University. My passion for public safety and security will be enhanced when I obtain a Masters degree as I will learn to design and implement effective policies related to eme rgency response and preventative techniques for the Canadian soldiers in order to increase the protection at our borders and airports.Upon completion of the program, I will be prepared to occupy the senior management level position and write new policies, procedures and regulations as well as updating existing ones. I will also be deployed to Afghanistan and several overseas missions throughout my career. The knowledge and skills that I will gain will be used to aid Canadian soldiers, NATO allies and UN personnel who are affected by natural disasters and acts of terrorism. The 911 incidence awakened my passion to be totally committed in safeguarding Canada and protecting the lives of my countrymen.The potential threat to our security has increased tremendously after 911. Something has to be done and I believe that I have a role and a mission in protecting the interest of the Canadians. The birth of the Masters in Disaster and Emergency Management program at York University is the to ol that will help me become professional in this field. The battle cry for a secured and peaceful Canada can never be ignored and nothing can stop me from reaching my goals. References: HeartQuotes (2007).   â€Å"HeartQuotes: Quotes of the Heart†.

Francis Bacon

Francis Bacon's Essay of Love Sir Francis Bacon was a famous English essayist, lawyer, philosopher and statesman who had a major influence on the philosophy of science. In his time Bacon wrote sixty different essays. He devoted himself to writing and scientific work. His experiences make him an expert on the topic of love. Francis Bacon's essay Of Love is an essay about love. The purpose of the essay is to explain love and the affects It has on all kinds of people.The essay Informs the redder that no matter what type of person you are love will have an effect on you, There Is no escaping It. Bacon states, â€Å"For there was never proud man thought so absurdly well of himself, as the lover doth of the person loved; and theretore it was well said, that it is impossible to love, and to be wise. † The translation of this statement is that love makes us do crazy things. Bacon's intended audience to his essay is everyone who has been in love or contemplated about being in love. No one type of audience is excluded from this essay because love affects everyone.The author assumes that we all know what love is but he wants us to understand that love, whether contemplated by persons with strong characters r weak characters, love has the power to affect both, The example 3acon uses Is Marcus Antonius who Is described as voluptuous and Inordinate, meamng given to excess. He also uses the example of Appius Claudius who Is described as austere and wise These two men are very different in character, but that does not matter. Love is going to affect them in one way or another.Bacon states, â€Å"Love can find entrance, not only into an open heart, but also into a heart well fortified, if watch be not well kept. † Bacon's point of view is directly stated in the essay. It says, â€Å"By how much the more, en ought to beware of this passion, which loseth not only other things, but itself! † What Bacon is trying to say is that mankind needs to be aware of the powers of love. The key problem that Bacon addresses Is that people may think that because they possess certain characterlstlcs that love cannot affect them or they think they have some sort of control over It.Bacon wants his readers to understand that love Is does not respect character. No matter who you are or who you think you are love will affect you one way or another throughout your lifetime. The thesis of the essay is stated learly in the first sentence of the first paragraph. Bacon states, â€Å"You may observe, that amongst all the great and worthy persons (whereof the memory remaineth, either ancient of recent) there is not one, that hath been transported to the mad degree of love: which shows that great spirits, and great business, do keep out this weak passion. One key passage In the essay states. â€Å"This passion hath his floods, In very times of weakness: which are great prosperity, and great adversity; though this latter hath been less observed: both which times k indle love, and make It more ervent, and therefore show it to be the child ot folly. Bacon tries to explain here that love affects whether in good or bad times. Bacon also wants his reader to understand to keep love in its place instead of letting it rule other aspects of life.The essay's example of this is the key passage, â€Å"They do best, who if thy cannot but admit love, of life; for if it check once with business, it troubleth men's fortunes, and maketh men, that they can no ways be true to their own ends. † There was no point in this essay that I could predict its organization. The organization is confusing because of he difficulty of the language. Bacon's essay is written in the form of one big paragraph, so there are no signals to new sections of the essay. Bacon speaks on the same topic throughout the entire essay.He uses descriptions of other people's experiences as evidence as well as to support the thesis. Bacon's tone in the essay is preachy. It is like that of a sermon because he uses examples for you to follow. If you cannot control your love or passions then keep love in its place. Dont let your love effect or control the aspects of life that it doesnt need to effect. The sentences and the vocabulary are very difficult. Words like, austere and reciproque are used. These are obviously not everyday used words.Understanding the vocabulary makes understanding the entire essay easy. The key word that is recurred throughout the entire essay is the word love. Before the essay even begins a side note that Bacon has is, â€Å"The stage is more beholding to love, that the life of man. For as to the stage, love is ever matter of comedies, and now and then of tragedies; but in life it doth much mischief; sometimes like a siren, sometimes like fury. Here, Bacon is trying to get across that love goes through many different stages in life.Bacon states in the last sentence of the essay, â€Å"Nuptial love maketh mankind; friendly love perfecteth it; but wanton love corrupteth, and embaseth it. † Here Bacon is trying to get across to his reader's that the love between a man and a woman make mankind, the love of friends perfects mankind, but immoral and cruel love corrupt mankind. In 1 Corinthians 13:4-8 and13 of the Bible states, â€Å"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.Love does not delight in evil but rejoices with the truth. It always hopes, always perseveres. Love never fails. And now these three remain: faith, hope and love. But the greatest of these is love. † And because love is all these things Bacon wants his readers to understand there is no escaping love. Love is all around us, no matter who you are love, affects us all. After reading this essay my opinion is the same as Bacon's. I do believe there is no escaping love. It asnt until researching Bacon a little bi t that I found that my interpretation of this essay was wrong.Bacon preferred masculine friendship to heterosexual love, he states â€Å"although nuptial love maketh mankind, friendly love perfecteth it. † His essay on heterosexual love is a critique of the â€Å"weak passion. † He is speaking of love between men when he says â€Å"a crowd is not company and faces are but a gallery of pictures, and talk but a tinkling cymbal, where there is no love,† and â€Å"If a man have not a friend, he may quit the stage. † This comes from his essay â€Å"Of Friendship. â€Å" Francis Bacon Francis Bacon’s Philosophy of Science In 1620, Francis Bacon; the philosopher and creator of Empiricism made a great contribution in defining the course of modern science by a breakthrough in process of scientific reasoning and method. Bacon did not propose an actual philosophy of science rather a method of developing philosophy. He demanded science based on induction. While being the first in the philosophy of science, Bacon discovered that Aristotle methods taught scientists nothing about the universe.The contributions Bacon made to the philosophy of science impacted the involvement of psychology today. Bacon was greatly influenced by the Renaissance period and made an impact in the modern era of knowledge (Ochulor, 2011). Francis Bacon believed that empiricists gathered important information, but had little idea on how to use their knowledge. Bacon made many contributions to the history of the philosophy of science, but the biggest was the idea of experimental science. He b elieved research could be used to test real world observations. According to Bacon, science should include no theories, no hypotheses, no mathematics, and no deductions but should involve only the facts of observation† (Esper, 1964). Bacon had little trust in rationalism due to its emphasis on words, and he distrusted mathematics because of its emphasis on symbols. He trusted only the direct observation and recording of nature. With Bacon being a radical empiricist, he stated the ultimate authority in science was to be empirical observation. Positivism was later the name of Bacon’s approach to science.Bacon advocated the theory of dual truth; truth of reason and truth of revelation. Bacon referred reason to revelation as the source of philosophical and scientific reasoning which can lead one to believe him as a rationalist but more of an empiricist. â€Å"For Francis Bacon, it is only through the concept of experimentation and observation that one can arrive at true kn owledge† (Ochulor, 2011). The idea of the inductive method was brought into modern science and philosophy and believed it was the surest way to knowledge. Francis Bacon had many contributions to modern science, but he had many weaknesses to follow.The major weakness Francis Bacon had was the lack of hypothesis. Throughout history one knows in order to prove something in science is to have a hypothesis. Bacon suggested, â€Å"One may look at facts and the hypothesis would suggest itself† (Ochulor, 2011). Although Francis Bacon’s life was not without controversy, he remained a leading thinker in philosophy and was well versed in the field of scientific methodology. Bacon as well as other Empiricists believed that the mind was a blank slate and that all knowledge and ideas developed though the senses and through experiences.Francis Bacon used the idea of inductive reasoning to develop the idea that science prospers through observation and experience. This included t he study of the mind. The study of science and the study of the mind came about through Francis Bacon’s efforts as well as others that influence Psychology today. References Esper, E.

Refugees Essay Example | Topics and Well Written Essays - 500 words

Refugees - Essay Example by reporting on the High Level Dialogue on International Migration and Development’s 2013 meeting, which was hosted by the Permanent Observer Mission to the Holy See to the UN to discuss response to the refugee crisis (cmsny.org, 2013). In discussing the refugee crisis, the article highlights the countries that have had to deal with the refugee crisis, as well as the main challenges they face in hosting refugees. According to the writer, other countries should be doing more to assist in the refugee crisis by giving more aid and assistance to the host countries and partnering with them for long-term solutions. This is important to ensure that the situation is not made worse by inability of host countries to admit refugees. The article’s main argument holds that the slow response by the international community, aside from Syria’s neighbors, will worsen the already critical refugee situation. The refugee crisis has resulted in over one million children living in refugee camps and camps for the internally displaced, which has placed them in danger of exploitation through trafficking, early marriage, and child labor (cmsny.org, 2013). In addition, the crisis has also affected fellow refugees from Palestine, Iraq, Sudan, Afghanistan, and Somalia, who have had to flee most parts of the country. This mass exodus of humans from Syria to neighboring countries has burdened host countries with extra budgetary expenses, which will only worsen as the war drags on. Any more significant numbers of refugees will place huge economic and social burdens on the host countries (cmsny.org, 2013), which may turn refugees to maintain their own countries’ socio-economic wellbeing. In making this argument, the writer makes the assumption that there will be no cessation of hostilities and that the refugee crisis will only get worse as more of Syria becomes a war zone. In my opinion, it is important that other countries become in the mitigation of the Syrian refugee crisis. This is

Specific Language Impairment Term Paper Example | Topics and Well Written Essays - 500 words

Specific Language Impairment - Term Paper Example In some cases, they are due to a physical problem such as hearing loss; in others the delay is short and children catch up quickly with their peers. But about 4 per cent of children have a specific impairment that has no physical cause but requires clinical attention (Watkins, 1994). These language impairments take several different forms. Some children have problems with making the correct sounds, others with classifying speech sounds (not recognizing that ‘pat’ and ‘potato’ begin with the same sound, for example) or get sounds in the wrong sequence. Grammar can also pose problems: some children aged six or seven talk in a babyish way, using short, ungrammatical sentences such as â€Å"yesterday I go to school† (Watkins, 1994). Professor Dorothy Bishop, a Welcome Trust Principal Research Fellow at the University of Oxford’s Department of Experimental Psychology, has been investigating this complex group of deficits and their many associated risk factors and syndromes (Leonard, 2004). Using a wide range of techniques – including experimental psychology, electrophysiology, genetics and language assessment – she is working to characterize the disorders and understand their origins. Professor Bishop has found that most children with specific language impairment have several underlying problems. The picture emerging is that there are multiple risk factors for specific language impairment that do not cause problems if they occur alone, but in combination with other deficits they do (Watkins, 1994). For example, electrophysiological studies have found that some children show unusually rapid decay of memory for incoming sounds. This is also found in the parents, even if they have no language difficulties themselves. Impairment results when this poor short-term memory is combined with other traits such as poor discrimination of word sounds (Watkins, 1994). In studies on twins and the parents of

Re-evaluation before the Development of Technology Essay

Re-evaluation before the Development of Technology - Essay Example Man required various tools for use in hunting, gathering fruits and tubers used as food, as well as weaponry for protection against the attack by animals. This led to the use of stone tools, which were shaped appropriately, then, to the wooden and later to the metallic tools, which required further systems of shaping and designing them for appropriate application (Berkman, 1962). With the need to shape the metallic tools, technological need arose, which would melt the metal and then shape them into various tools. Secondly, the need for locomotion started with forging rafters to be used for moving across streams, paving way for the development of masts to harness the wind and use it to propel the boats, and later the development of steam-powered engines. All these were steps in the technological development. b. Near past The controversy in the Near Past phase of technological development is the environmental degradation, the negative effects of the GMO food on human health and the une mployment caused by the replacement of the human workers by machines in industries and various business firms. The near past technological development counts for the period between the 20th and the 21st century, where technological advancement emerged in the form of development of road transport and the automotive industry, office work technologies, manufacturing and other business operational technologies, as well as advancement in air industry (Swaminatha, 2011). Further alternative sources of energy such as nuclear were exploited, while great strides were made in the agricultural sector with the development of the genetically modified organisms (GMOs), as well as various agricultural production technologies. Further advancements were made in the field of medicine and public health with organ transplants technologies evolving, as well as many other life-saving technologies. The communication technology further advanced with the arrival of mobile phones and other communication devi ces. c. Currently i. Current status of the issue The controversy in the current phase of technological development is the threat posed by the internet and cybercrimes on the welfare of the people, as well as the threat of the nuclear weaponry development, which is posing the threat of a third World War, which may have worst consequences, than any other war that has been experienced in the world. The current phase of technological development is marred with computer technology, internet technology and the nuclear weapon technology, all of which have made the fear of the worst war ever occurring. Through the internet and the computer technology, the threats of terrorism in the world have increased immensely, while the online frauds and financial scams have posed a great threat to the online business operations (Swaminatha, 2011). ii. Division in attitude towards the claim There are major supporters of the technological development due to the advantages it has brought to the modern wor ld such as the ease of communication through the mobile devices as well as the internet platforms such as social media, the ease of buying and selling commodities through online marketing platforms and the improved knowledge creation and sharing through the internet

Psychological Testing and Assessment Selection Paper Research

Psychological Testing and Assessment Selection - Research Paper Example An expectancy table provides an indication or prediction of the possibility that the scores of a person taking test will lie within interval on the measuring criterion that qualify categorization as failing, passing or acceptable. For instance, an expectancy table applied in experimental test on personnel in an employment setting may show that the higher the score of a worker on a new test is a prelude that the worker may be gain approval as successful. Commonly used expectancy tables include Naylor-Shine tables and Taylor-Russell tables (Cohen, Swerdlik & Sturman, 2013). Decision theory and test utility are another combination or resources that can help a counselor select a psychological test or assessment. Decision theory provides guidelines for setting cutoff point for particular scores recorded from tests. Another tool that counselors can use in selecting a psychological test or assessment is the Brogden-Cronbach-Glaser formula (Ployhart & MacKenzie, 2011). This is mostly useful in calculating the amount of dollar of utility retrievable from the use of particular instrument selected under a given condition. A counselor selecting a psychological test for a client needs to consider the four issues that include difficult-index of an item, reliability and validity indices of items and discrimination index. To determine an item’s difficulty index, one has to calculate the proportion of the number of test takers that answered an item in correct way. Usually, a lower case â€Å"p† helps in denoting item difficulty with subscript to show an item’s number. Cohen, Swerdlik and Sturman (2013) educate that the value of item index can range from zero incase everyone failed the item and one incase everyone passed the item. The larger the item difficulty index, the easier is the item, and the smaller the item difficulty index, the tougher the item. Easier items scored by all people and difficult items failed by all test takers are inappropriate

Hamlet Essay Example for Free

Hamlet Essay What have you come to understand about the intense human relationships of Hamlet? How has this understanding been affected by the perspectives of others? In you response you should focus on 3 scenes in the play and a range of perspectives. The intense human relationships of Hamlet have been viewed through numerous perspectives yet all have reached the same conclusions. With the exception of just one, the friendship of Hamlet and Horatio, all the relationships are dishonourable, dysfunctional and destined to fail. Being a revenge tragedy it is immediately clear this play is filled with lies, deceit and treachery. The exact time of Hamlet’s composition is unknown, however it is assumed to be between 1599 and 1602. This was a dark, melancholy time in Shakespeare’s life with the death of his father in 1601 and the death of his only son, Hamnet aged 11, in 1596. It is believed that these events had a significant impact on the writing of Hamlet as the play is heavy with death and has a great similarity with this son’s name. Some perspectives that have been adopted to view and understand the intense human relationships of Hamlet are a religious, psychoanalytic and feminist perspective. When Shakespeare first wrote Hamlet he lived in a strongly religious society where people could be fined for not attending church. Therefore, at this time in history many people had a religious attitude and perspective on the play. The psychoanalytical perspective focuses on the unconscious mind and how it dictates behaviour. This perspective became popular when Sigmund Freud, a well-known psychologist, began developing his psychoanalytic theory, The Oedipus Complex, in 1897. The feminist perspective is often centred around strong women and became particularly popular in the 1950’s being a post world war 2 period. Women were involved in many aspects of the war and made ground in their equality with men. However, when the war ended, women were encouraged to return to their household duties and this sparked much controversy. The family relationship between Hamlet and Gertrude is one of the most intense in the entire play. Their relationship reaches a climax in act 3 scene 4 when Hamlet confronts his mother about her relationship with Claudius and her involvement in the murder of King Hamlet, â€Å"mother, you have my father much offended†. Hamlet sees Gertrude as an adulteress for marrying her husband’s brother two months after his death and believes she is aware that Claudius killed King Hamlet, â€Å"Almost as bad, good mother, As kill a king and marry with his brother†. When exploring this scene from a feminist perspective it can be seen that Gertrude cares deeply for her son yet he scorns her for her recent actions, â€Å"You go not till I set you up a glass where you may see the inmost part of you†. Despite there being no evidence that Gertrude is aware of Claudius’s deed, Hamlet does not trust his mother and this consequently results in his inability to trust other women. The Oedipus Complex comes to the fore when the relationship of these two characters is examined with a psychoanalytical perspective. Freud’s complex suggests that every boy from the age of 3-4 years begins to have unconscious sexual desires for his mother and regards his father as his rival. Through studying this scene from a psychoanalytical perspective it is prominent that Hamlet has an obsession with his mothers sexual relationship with Claudius. He claims that she lives â€Å"In the rank sweat of an enseamed bed†. The scene takes place in Gertrude’s bedroom, which is important as its privacy and intimacy allows Hamlet to express himself fully to his mother and being a place where sexual activity occurs, suggests Hamlets repressed sexual desires. The scene ends with Hamlet possessively demanding her â€Å"but go not to my uncle’s bed† and uses multiple sexual references when he tells her to not let Claudius â€Å"Pinch wanton on your cheek, call you his mouse†. Relating this to the Oedipus complex, Hamlet appears to be more like a jealous lover than a concerned son. Examining act 3 scene 4 from different perspectives gives varied insights into Gertrude and Hamlet’s relationship, yet each perspective deduces that it is a dishonourable relationship with no mutual trust or respect. Another dishonourable family relationship in Hamlet is that between Ophelia and her father Polonius. Polonius manipulates Ophelia for his own benefit, treating her like a tool rather than a person. Their relationships becomes pitiful when she receives orders from her father and responds with â€Å"I shall bey, my lord†, implying that she is at the service of her father. Through the analysis of act 4 scene 5 a deeper understanding can be reached about Ophelia’s relationship with her late father. Following the death of Polonius, Ophelia’s mind becomes unhinged as she drifts into insanity, speaking in songs and rhymes. Considering this scene from a feminists perspective it can be thought that Ophelia went mad with guilt having her desire for Hamlet to kill her father so that they can be together fulfilled. This theory strongly supports the idea that the relationship between Ophelia and Polonius was dysfunctional as she felt she’d never be free to make her own choices until her father was dead. The friendship between Hamlet and Horatio is the only admirable one. Horatio is the one character that Hamlet speaks to openly and confides in. He remains loyal and swears himself to secrecy about the ghost and the pretence of Hamlets madness. He conspires with Hamlet to prove Claudius killed King Hamlet and he stands by him through Ophelia’s death. It is the final scene of the play when the true extent of their friendship is confirmed. Act 5 scene 2 begins with Hamlet confiding in Horatio and reciting the fate of Rosencrantz and Guildenstern to him. This further validates their friendship and Hamlets trust in his loyal friend. The scene draws to a close with Horatio wishing to join Hamlet in death. This selfless declaration and his final words to Hamlet before he dies â€Å"good night sweet Prince, and flights of Angels sing thee to thy rest† convey his everlasting faithfulness to Hamlet. Through examining the friendship of Hamlet and Horatio from the beginning of the play to the end, it is clear that, unlike all the other relationships, there is never a doubt about the sincerity of their friendship. Through the close and critical analysis of Hamlet, you can come to the understanding that all but one of the intense human relationships within the play are dishonourable, dysfunctional and destined to fail. Considering this interpretation in the light of other perspectives the same conclusion can be drawn about the relationships.

Possible theories for crime: Nature versus Nurture.

Possible theories for crime: Nature versus Nurture. Crime is a matter of popular interest and focus; it is everywhere you look from newspapers to cinemas. Criminal acts have the ability to repel and fascinate us at the same time. When violence occurs we want answers. One of the questions people often ask when hearing of a crime, whether it be burglary or murder, is why? What causes criminal behaviour? Unless we know what causes an act of violence it is hard to put it behind us. The search for the causes of crime continues to form the basis of most criminological studies. There are numerous explanations for crime; biological, economical, geographical, psychiatric, psychological, sociological. However, broadly speaking these causes generally fall into two basic schools of thought, nature and nurture, and while most of us will embrace notions from both sides, some criminologists tend to lean more in one direction than the other. Psychological theories of crime hold the view that individual differences in behaviour may make some people more predisposed to committing criminal acts. These differences may arise from personality characteristics, biological factors or social interactions. As there are so many theories for criminal behaviour this paper will focus on the biological and environmental factors, which may account for the growing social problem of violent and antisocial conduct. It was an urgeà ¢Ã¢â€š ¬Ã‚ ¦.a strong urge, and the longer I let it go the stronger it got, to where I was taking risks to go out and kill people-risks that normally, according to my little rules of operation, I wouldnt take because they could lead to arrest. Edmond Kemper (cited on http://www.crimelibrary.com) Where does this urge come from? Do we all possess it and if so, what stops some people from committing crimes, whether it be murder, as in this case, or something less, whilst others cannot control this urge. It could be said that criminals have no control over their impulses, whereas we do; no matter how angry we get there is something that stops us from taking this anger out on other people. According to Sigmund Freud (1856-1939) all humans have natural drives and urges repressed in the unconscious. More importantly he also claims that all humans have criminal tendencies. It is through the process of socialisation that these tendencies are curbed by the development of inner controls that are learned through childhood experiences (Eysenck, 1977). Maybe the thing that stops us is the thought of the punishment we would receive if caught, or maybe it is morality or social programming. It may even be that we are afraid that if we commit a crime and are caught, we risk losing the social bonds that we have with other people, as they will then think less of us. Humans are knowledgeable people who understand a great deal about the conditions and consequences of what they do in every day life (Farrell, Bowling, 1999). Once convicted of a crime and in court, there is an increased emphasis upon the free will and moral responsibility of the offender for their actions. However the conception of the offender being genetically at risk has now emerged. There have been numerous studies carried out on twins to determine whether genetic influences play a part in criminal behaviour. Christiansen (1977) reported on the criminality of a total population of 3,586 twin pairs from Denmark. He found that 52% of the twins were concordant for criminal behaviour for identical twin pairs, whilst 22% of the twins were concordant for fraternal twin pairs. These results suggest that identical twins carry some form of biological characteristic that increases their risk of becoming involved in criminal behaviour (McLaughlin, Muncie, Hughes, 2003). However, the thought that criminal behaviour is due to genetics poses many questions. At a personal level, people wonder about how much actual choice they have over their lives. Accepting genetic causes for their traits can relieve guilt about behaviour they want to change, but cannot. According to Gibbons (1968), the genetic theory indicates that inherited traits are specific in nature, i.e. so that a person inherits green eyes and blonde hair. However criminal behaviour is not specific, it covers a wide range of criminal activities from petty theft to mass murder. Also, many criminals engage in a range of these activities, not always one specific type of crime, therefore how can the genetic theory account for this variability? It could be suggested that criminals inherit general tendencies to break laws. However criminals do not break all laws, they obey to most. It is very difficult to demonstrate any feasible mechanism for the inheritance of criminality (Eysenck, 1977). A disorder such as Cystic Fibrosis is a disorder produced entirely by hereditary causes. The cause is known and understood and the presence of the disorder can be determined with accuracy. With this in mind, what kind of structure can be imagined to underlie the cause of crime? What is criminal in one country may not be criminal in another country; the purchasing of marijuana is legal in Amsterdam whilst illegal in many other countries. Also, what is a crime at one time may not be a crime at another time, i.e. it is a citizens duty to kill in war but outside of war it is a crime. People are able to understand the differences in situations like these. What some people do find difficult is the thought that a gene or chromosome may cause the difference between a criminal and a non-criminal (Eysenck, 1977). In a study carried out by Bernhardt (1930) on two groups of siblings, group one had both parents as none criminal, but criminality was among the grandparents or other close relatives, and the second group had no criminal parents or other relations. He found twice as high a crime rate among siblings in group one, than in group two, and postulated that this difference must be endogenously caused, as both groups of children grew up in non criminal homes. As can be seen from this study, it is difficult to eliminate environmental factors. There is always the possibility of direct influence from grandparent to grandchild. It may also be assumed that grandchildren of criminal grandparents are exposed to less favourable environmental influences via the intermediate parental link. Plus, the probability that the environment the parents create for their children is much the same as the grandparents created for the parents, is very likely. The biological side of criminal behaviour can be studied through mental patients. In a ten year follow up of criminality in Stockholm mental patients, Belfrage (1998) found new evidence for a relationship between mental disorder and crime. The study was carried out on 1056 mental patients with the diagnosis of schizophrenia, affective psychosis or paranoia. After they had been discharged from mental hospitals in 1986, they were followed up ten years later. It was found that of those who were forty years old or younger at the time of discharge, nearly 40% had a criminal record, compared to less than 10% of the general public. According to Soothill, Peelo and Taylor (2002), on a typical day, four mentally disordered offenders are admitted from the courts to Broadmoor hospital, Rampton hospital or Ashworth hospital on hospital orders. Also, about one offender a day is transferred after sentence from a prison service establishment to a hospital. However some criminologists regard biological evidence with alarm. Nelkin and Lindee (1995) believe that genetics, in relation to crime, deflects attention from the need for social reform, education and rehabilitation in tackling the violence in society. The study carried out by Komiya (1999) highlights the importance of environmental factors, such as families, schools and companies, concerned with the individual. This study was concerned with looking at the low crime rate in Japan in relation to the cultural background. It found that reasons for low crime rate were due to factors such as low unemployment, high educational standards, strict justice in relation to the control of firearms and drugs and the certainty of arrest, self-discipline and the high level of self-control. This latter is regarded as the strongest weapon for survival in Japan and they learn the value of self-control at a very early stage in life. It is the most important stage of socialization in Japan, whereas in Western countries a self of sense is most important. The socialization in Japan happens through/in families, schools and companies. In the family, children are under strict discipline. They learn to accept parental authority; therefore they are driven by parental expectations. There is lots of body contact i.e. bathing with parents. This is the opposite of Western families who encourage their children to have their own bedroom. In the school there are lots of regulations and children also have peers. The companies provide security i.e. lifetime employment, medical support, retirements benefits. For this, Japanese workers must accept strong informal social control by their company. As can be seen through this study Japan has a strong sense of security and an infinite number of repressive rules. These two elements act together to produce high levels of self-control, which acts as a strong force restraining people from committing crimes. The Japanese legal culture contributes to the prevention of crime by controlling the individuals behaviour. This is the opposite to the Western worlds emphasis on the permissive nature of rules and the relative freedom of action. According to Komiya (1999) this suggests there is a trade off between low crime rates and a strong awareness of freedom. If individuals have a strong sense of responsibility, a society can lower its crime rate without undermining freedom. It could be said that a persons environment depends to a certain extent on his/her own choice (Horwitz, Christiansen, 1983). It could also be that some individuals within certain areas are drawn into crime (McGuire, Mason, OKane, 2000). A case in which the latter may apply is institutional upbringing. There seems to be a stigma attached to children raised in an institute; they are labelled as social deviants. However it must be remembered that children placed in these institutes, before being removed to the institute, are already in a rather threatened situation. Therefore it should be expected that these children would show increased delinquency rates. However once a person is stigmatised by a label, the response is often to fulfil the label given and commit further acts of deviance. To take a quote from http://www.crimelibrary.com, I have several children who Im turning into killers. Wait till they grow up. David Berkowitz This illustrates how much of an impact the environment in which a child grows up in has later on in life. Reading this quote would definitely worry criminologists who believe that the environment shapes a person and influences later life choices. Some parents believe that by being harsh on a child will toughen the child up. Instead, it often creates a lack of love between parent and child that can have disastrous effects later on in life. If a child does not bond with his/her carers there is no foundation for trusting others later in life (http://www.crimelibrary.com). Bowlby (1957) carried out a study on 44 thieves at a psychiatric clinic. He believed that a long separation from the mother during the first five years of a childs life is a leading cause in the development of socially incapable, troublesome and delinquent personalities. Other studies claimed that the absence of the father might also create an equally dangerous risk (Horwitz, Christiansen, 1983). Andry (1955) found tha t the absence of the father was as equal a risk as the absence of the mother, and re-established the father as an equally important figure (Horwitz, Christiansen, 1983). Either way, both researchers found that parents are very important in the development of children. A criminal can often be heard blaming his/her actions on a number of traditional explanations; childhood abuse, genetics, exposure to traumatic events and perceived social injustices to name a few. However the problem with this is that many people have been exposed to one or more of these traumas, yet they do not turn to crime. Maybe it is an interaction of a number of factors. Yet in the case of Jeffrey Dahmer, who had an apparently normal upbringing, environment does not seem able to explain the behaviour displayed. If there is a genetic explanation, it is difficult to explain, as we do not see entire families of, in this case, serial killers. Another aspect of crime, which is of interest, is understanding how and why offenders stop committing offences. This is crucial for the development of effective crime prevention and criminal justice practises. Without a theory as to why people stop offending it is difficult to know which policies and practises are best needed to stop it. Some criminologists believe that by searching for the causes of criminality, the attention is taken away from the pressing task of crime management (McLaughlin, Muncie, Hughes, 2003). This essay has only just begun to skim over the causes of criminal behaviour. As can be seen it would be difficult to credit one theory for the explanation of crime, there is a continual interaction between both genetic an environmental factors; they are functionally interdependent. No one study carried out can be said to provide conclusive evidence for either genetic factors or environmental factors (Horwitz, Christiansen, 1983). However if genetics were to be seen as the cause of criminality, this would pose future problems; it may lead to genetic screening for the interest of risk assessment. This could lead to genetic discrimination, which could then lead to loss of employment or denial of insurance or other benefits (Rose, 2000). If crime were due to genes, the individual would not be to blame yet they would be punished through the mentioned ways. There must be something in the child himself which the environment brings out in the form of delinquency. This quote by Aichorn (Gibbons, 1968) demonstrates the importance of both nature and nurture acting together. Certain aspects of each theory help us to understand the criminals behaviour, and it is through this interaction that we are able to further our knowledge on criminology. Awareness of Students in Junk Food Consumption | Proposal Awareness of Students in Junk Food Consumption | Proposal Izyan Hanim Binti Ibrahim THE AWARENESS OF STUDENTS IN PUSAT PERMATA PINTAR NEGARA IN CONSUMING JUNK FOOD CHAPTER 1 INTRODUCTION INTRODUCTION World Health Organisation has stated that the dispersion of disease mainly is caused by the unhealthy eating lifestyle (As cited in CSE 2012). However, the adolescence really love eating junk foods including burgers, carbonated drinks, instant noodles, French fries, hotdogs, sweets, potato chips and biscuits (Arya Mishra 2013). According to Arya Mishra (2013), they have classified adolescence stage into three stages which early adolescence, ranging from 11-14 years old, middle adolescence, teenagers of age 15-17 years old and lastly late adolescence that have ages of 18-21 years old. Those stages are the most important stages in human life cycle because during early adolescence is the emotional management stage due to it is a puberty level. Moreover, in the middle adolescence is the try-and-error stage because teenagers tend to try many new things and experiences and last but not least teenagers will figure out his or her future plan during the late adolescence stage. The study has stated that wrong consumption of nutrients at this level will result a prolong impacts to them. Students of Pusat Permata Pintar Negara are the gifted students and their specialties should be preserved. This study will survey the awareness level of them in taking in the junk foods to make them realise how dangerous is the action. Students who live far away or without parents have higher tendency to consume or buy junk foods. A study has discovered that foods rich in nutrient have higher price index in marketing fields compared to the unhealthy foods like junk foods ( Deakin University 2008). Finally, this research project will reveals the frequency of those students in consuming junk foods from schooling session until living in the dorms session with others. Despite all of this, the researcher will investigate how the examination year will affect the frequency of their consumption towards junk food in order to enhance the cognitive level. BACKGROUND Junk foods are categorised as any types of meals that can be prepared in short time and does not require much energy to make it (Johnson et al. 2012). However, Escalante et al. (2004) has stated about the intake of beneficial nutrient decrease as the consumption of junk food increase in children’s meal. This is one of the implication the over exposed children to the junk food advertisement continuously in front of television. For instances, the advertisement that make a non-stop promotion is Koko Krunch, Coca Cola, Pepsi Co and biscuits. Yosifon(2006) also support this claim about the effect of advertisement in monopoly the young generation’s mind. In addition, World Health Organisation (WHO) has come out with a result those actions is one factor that contributes to the increase of statistical analysis on the Body Mass Index (BMI). Company of junk food will target the new generation as their marketing customers to exploit the profit (Yosifon 2006). Junk food is rich with salt, trans fat, sugar and many chemical contents as their preservative and addictive agent. Monosodium glutamate is the most well-known food addictive agent in junk food. Monosodium glutamate is one of a dangerous chemical that always being related with the development of cancer cell. As has been stated before, junk food is a food rich with fat. The consumption of high fat meals will make the signal of appetite-supress is being ignored and leads to increase of appetite and gaining weight (Johnson et al. 2012). Not to be forgotten, Johnson et al. (2012) also have made a study on the effect of junk food on brain. The study has proved that junk food can reduce the volume of brain. The reduction of brain capacity will lead to the neuro diseases. For students, the ability to memorise is important for the process of cognitive. So, the risk to be effected with Alzheimer’s disease should be lower by taking care of intake of junk food and aware with the intake of nutrients. 2 As conclusion, this research mainly wants to study the awareness of gifted students in the consumption of junk food and to determine whether examination year will affect the consumption of junk food in their diets. PROBLEM STATEMENT Teenagers are the main target for any company of junk food to be their customers. So, junk food has becomes one of their favourite food. Besides, the problem that has been observed by the society about this issue is the source to get this junk food can easily bought by the students and there is no restriction. For examples, many types of junk food can be bought from the vending machines, school canteens and the nearby grocery shop (Datar Nicosia 2009).As students; they should spend the money wisely. So, they eat junk food because it is affordable and cheap. However, obesity cases among the young generation is rising up and continuously year by year (Escalante et al. 2004). PURPOSE OF RESEARCH The purpose of conducting this research is to study the awareness level among students of Pusat Permata Pintar Negara in consuming junk food in their diets. Junk food contains many types of chemicals and the most well-known chemicals present in that food is monosodium glutamate. Monosodium glutamate can produce an addictive flavour that enhances the taste of the foods (Husarova Ostatnikova 2013). As students, the frequency of taking junk food will be investigated by the researcher and to determine whether the examination year for Form 5 student, that will facing Sijil Pelajaran Malaysia, will control them from taking the junk food. RESEARCH OBJECTIVES To determine whether students of Pusat Permata Pintar Negara aware about the intake of junk food. To study the frequency of students consuming junk food. 3 To investigate whether the examination year will affect their intake of junk food. RESEARCH QUESTIONS The research questions are: Does the students of Pusat Permata Pintar Negara aware about the intake of junk food? How frequent is the students consume junk food in their life routine? Does the examination season will affect the intake of junk food among the students of Pusat Permata Pintar Negara? RESEARCH HYPOTHESIS Alternative hypothesis, : The examination will affect the frequency of consuming junk food by the students. Null hypothesis, : : The examination will not affect the frequency of consuming junk food by the students. SIGNIFICANCE OF RESEARCH This research is mainly done because teenagers nowadays are known as junk food generation because there are many of them that take in junk food as their main dishes every day. So, this research is one of a step towards reducing the intake of junk food especially among the students. The significance of this research is to enlighten the society about the dangerousness of junk food in harming the health. Besides, this research will highlight the seriousness 4 level of consuming the junk food in diets of students. LIMITATIONS The samples of this research are just from a small population of Pusat Permata Pintar Negara which have a total number of students of. Due to small population, the sample used for this experiment will be a small sample size. The small sample size may not have a statistical support due to insignificant result of the finding for this research project. DEFINITION OF TERMS The definition of each main concept in the research is as follows: AWARENESS The awareness of students in Pusat Permata Pintar Negara in this research is about how they control the intake of junk food even they know its implication on health. Moreover, it becomes serious when students tend to chewing something during study or revise in the night. FREQUENCY The frequency of eating the junk food gives an idea to the readers about the number of consumption of junk food per day or per week. COGNITIVE The ability of students to understand their studies CONCLUSION The awareness of students in Pusat Permata Pintar Negara should be investigated through this research since they are the gifted students that need to preserve their specialities. Through this survey, maybe next research can study how to raise their awareness and decrease the consumption of junk food. 5 CHAPTER 2 LITERATURE REVIEW 2.1 INTRODUCTION Junk food is defined as any food that contains less in nutrients but rich in the inappropriate things such as the preservative and the additive agents. Junk food can contribute to obesity and encourages the eaters to skip their breakfast because of improper meals time (Gopal et al. 2012). The study by Gopal et al. (2012) has claimed about the bad effect of consuming junk food that the society does not realise is about the decreasing absorption of calcium in humans. Based on the survey by Gopal et al. (2012), their outcome of survey has shown that the biggest factor for the students to consume junk food probably is because of the taste of junk food itself. Almost 70% of the eaters agree with this factor and unfortunately almost half of them never care about the long-term effects. 2.2 CHEMICALS IN JUNK FOOD Chemical in junk food has a high glycaemic index and will suppress the appetite of the eaters. In addition, chemicals in junk food can higher the level of sugar more rapidly compared to other type of food (Vartanian et al. 2007). Monosodium glutamate, MSG, is a well-known chemical agents used in junk food and many studies has been conducted by using the animals as the samples to prove its effect on health. The usual experiment was conducted to study the implication on reproductive organs, central nervous system and adipose tissue (Husarova Ostatnikova, 2013). Overconsumption of junk food can reduce the size of lumen within age 30 and has a high risk to be attack by the coronary disease (Johnson et al. 2012). 6 2.3 METABOLIC SYNDROME Metabolic syndrome is defined as any disease that can lead to heart attack. For examples, high blood pressure, obesity, diabetes and obesity (Alberti et al. 2006). Husarova Ostatnikova (2013) has stated that chemical contents used in junk food can interrupt the metabolism process in humans’ body. â€Å"Junk food can increase the parameters of insulin, fatty acid and triglycerides in serum† (Husarova Ostatnikova 2013). They has been added that monosodium glutamate can increase the production of bile and the most dangerous element regarding this food addictive is it can change the structure of ovaries and fallopian tube. Besides, MSG can cause headache but the studied show there is no relationship between asthma and the uptake of junk food. Not only that, medical staff at Harvard University and University of Murcia can make the young men to distorted their reproductive system and development because the sperm produced will be the unhealthy sperm to fertilize with the ov um( Johnson et al. 2012). 2.4 PREVIOUS RESEARCH A study has proved that junk food’s nutritional content is approximately has zero content of nutrition. Furthermore, it has a large quantity of trans fat. Trans fat acts like the saturated fat which contributes to the increase in the statistics of obesity (Johnson et al. 2012). A statistical by World Health Organisation (WHO) shows that 2.8 million of humans were killed yearly due to the problems of body weight or obesity. This implication of junk food has been supported by British Heart Foundation (2014) that excess consumption of junk food will higher the risk of obesity. As the obesity has stated in an individual life, he or she will has a higher tendency to be infected by mane other diseases. The most common disease is the coronary disease. Not to be forgotten, illness that related to the obesity is high blood pressure, diabetes type II and development of cancerous cell. A recent article by Gutierrez (2014) states that junk food makes the eaters become addictive to it and the addictive level is like craving for heroin. In addition, the article also has claimed about the effect of over consumption of junk food will make the person will 7 refuse to the healthy meals and they prefer to starve themselves. When chemical content from junk food was entered the human body system, the biological content of brain will be deteriorated (Michelle 2014). It has been added that the entire body system will be interrupted especially the digestive system due to inappropriate digestive flow. A report by the Military Leaders for Kids (2010) has come out with a statement by the army that want all sources of junk food to be eliminated in school compounds either in canteens or vending machines. However, as a started step in order to remove the sources, conspiration between American Heart Association and the beverages companies was setting up to decrease 88% of the calories present in their product that will be in the school compound in United States. 2.4 CONCLUSION Consuming excess salt, sugar and many other unbeneficial needs to be controlled at the early age because obesity in young age will has a high probability to develop into adult obese (British Heart Foundation 2014). The awareness level of students in Pusat Permata Pintar Negara in consuming junk food should be studied so that next research can be conducted to find the appropriate ways in increasing their awareness. Students of Pusat Permata Pintar Negara are the gifted students that need to be preserved their intellectual level. 8 CHAPTER 3 RESEARCH METHODOLOGY 3.1 RESEARCH DESIGN Survey research method will be the research design for this study. 162 copies of questionnaires will be distributed among the students of Pusat Permata Pintar Negara, Universiti Kebangsaan Malaysia. The samples will be divided into three groups which is Form 4, Form 5 and Asasi Pintar students. Those groups have 54 samples each and a total of 162 students will be involved. There are three different levels of students because the researcher want to know whether the examination year will affect the consumption of junk food which is Form 4 students are not in examination year, Form 5 students are in examination year (Sijil Pelajaran Malaysia) and Asasi Pintar students are in the post-examination year. The questionnaire that will be distributed is from the Codman Academy. 3.2 RESEARCH PROCEDURE Based on Krejcie and Morgan table, the researcher can decide an appropriate number of samples. With the total number of population which is 280 students, Krejcie and Morgan table shows that the number of samples that should answer the Codman Academy questionnaire that will be distributed is at least 162 students. The result of the survey will have a valid result for the researcher to analyse. The questionnaire that will be distributed is taken from Codman Academy Junk Questionnaire Survey which already has its own validity. Therefore, pilot test is not necessary in this study . The questionnaire will be distributed among students of Pusat Permata Pintar Negara, Universiti Kebangsaan Malaysia. There are 15 questions involving questions on frequency of consumption of junk food by students of Pusat Permata Pintar Negara. The duration for collecting the questionnaires with the answers will be about 5 days. 9 The questionnaire will be analysed and the researcher will study on the frequency of consumption of junk food. In addition, the frequency of the Form 5 students for the intake of junk food will be compared with respondents from Form 4 and ASASIpintar students because the researcher wants to investigate about the effect of examination year on the frequency of taking junk food. 3.3 SAMPLE AND POPULATION 3.3.1 RESEARCH POPULATION The population for this research is the students of Pusat Permata Pintar Negara, Universiti Kebangsaan Malaysia that will answer the questionnaire. The total number for the population is 280 students including Form 4, Form 5 and Asasi Pintar students. 3.3.2 INCLUSION CRITERIA FOR THE STUDY SAMPLE The samples should be studying in Form 4 and Form 5 because they already pass the maturation stage in thinking skill. So, the answer can be more relevant and it is more valid to analyse it as the research result. 3.3.3 EXCLUSION CRITERIA FOR THE STUDY SAMPLE Students which are in Foundation phase or in Form 1 level cannot be selected to answer the questionnaire because some of them have matured but some of the students still have the immature way of thinking. So, the answer will be the irrelevant answers. The lecturers or teachers are excluded from the sample because the researcher want to study the awareness in the consumption of junk food among the students due to they are known as the junk food generation. 10 3.3.4 STRATIFIED SAMPLING METHOD The population will be grouped based on the age and the level of studying in school either the students are from Form 4 (16 years old), Form 5 (17 years old) or the post Sijil Pelajaran Malaysia candidates which are in ASASIpintar (18 years old). The sampling method will be conducted from each of the age of students’ ages. 3.4 INSTRUMENT 3.4.1 KREJCIE AND MORGAN TABLE This table gives the researcher a guideline in choosing the number of respondents needed for a certain number of population. The study will be conducted in Pusat Permata Pintar Negara which has a total number of 280 students including Form 4, Form 5 and Asasi Pintar students. So, a valid number of samples needed are 162 students. 3.4.2 CODMAN ACADEMY JUNK FOOD QUESTIONNAIRE Codman Academy Junk Food Questionnaire is taken as the questionnaire for this survey. The language used for this questionnaire is English language because it is a universal language. So, the respondents can answer the questionnaire without any obstacle due to language. 3.5 DATA ANALYSIS The result from the questionnaire will be analysed by using the statistics software known as SPSS. Results will be presented through frequency counts and other descriptive statistics. From the analysis, the researcher can get the statistical analysis on the result of the awareness of students in Pusat Permata Pintar Negara towards the intake of junk food. The hypothesis testing will be done by the researcher to make a decision. The decision is either to reject the null hypothesis or fail to reject null hypothesis. Microsoft Excel 2010 will be used to tabulate the data. 11 3.6 PRELIMINARY BUDJET 12 REFERENCES British Heart Foundation. 2014. Briefing: Junk food marketing to children campaign Husarova, V.

Wounded Knee :: American America History

Wounded Knee Wounded Knee was a terrible event in US history. It showed how the US government didn't understand the Native Americans and treated them badly and unfairly. Big Foot was the chief of a subtribe of the Lakota called Miniconjou. He was very old and had pneumonia. He was taking his tribe to the Pine Ridge Reservation in south-western South Dakota. Most of the women and children in Big Foot's tribe were family members of the warriors who had died in the Plains wars. The Indians had agreed to live on small reservations after the US government took away their land. At the Wounded Knee camp, there were 120 men and 230 women and children. At the camp, they were guarded by the US Seventh Cavalry lead by Major Samuel Whitside. During the year 1890 a new dance called the Ghost Dance started among the Sioux and other tribes. The Sioux's Christ figure, Wovoka, was said to have flown over Sitting Bull and Short Bull and taught them the dance and the songs. The Ghost Dance legend was that the next spring, when the grass was high, the Earth would be covered with a new layer of soil, covering all white men. Wild buffalo and horses would return and there would be swift running water, sweet grass, and new trees. All Indians who danced the Ghost dance would be floating in the air when the new soil was being laid down and would be saved. The Gh ost Dance was made illegal after the Wounded Knee massacre though. On December 28, 1890 the Seventh Cavalry saw Big Foot moving his tribe and Big Foot immediately put up a white flag. Major Samuel Whitside captured the Indians and took them to an army camp near the Pine Ridge reservation at Wounded Knee. Whitside took Bigfoot on his wagon because it was more comfortable and warmer, and Big Foot was sick. Whitside had orders to take the Indians to a military prison in Omaha the next day, but it never happened. That night Colonel James W. Forsyth took over. The Cavalry provided the Indians with tents that night because it was cold and there was a blizzard coming. The next day, December 29, 1890, the Cavalry gave the Indians hardtack for breakfast. There was a seize of arms and the soldiers took all the Indian's guns away. A medicine man named Yellow Bird told the Indians to resist the soldiers and not give up the guns, he did a few steps of the Ghost Dance.

Face to Face with Death in Hagar :: Hagar Essays

Face to Face with Death in Hagar As Hagar faces implications of growing old, she starts on a tumultuous journey, not one of her own choice, but one of destiny. She goes through different stages of denial, anger, bargaining, depression and finally acceptance of the fact that death will come, invited or not. At one time every individual is faced with death, horrific to the young, or inviting to the sick and the old. Death is interpreted as the end of existence, but to those who believe in the afterlife, as a whole new chapter of the unknown. When Hagar realizes the proximity of death, she is in denial. She comes to live in a world of memories in the past. She created her own illusion because she cannot understand the weakness coming forth in her, like her tears "the incontinent wetness of the infirm" (pg. 31). All her life, she was hard, never showing emotion, even through the death of John. You can see her softening near the end, although she would not admit it. In addition to denial, she reaches a stage of anger and indignance with herself and others in the small world that is her life. She can no longer perform the simplest tasks such as dressing herself or walking down the stairs. It irks her to need help, which is one of the reasons she can't stand Doris. She is also angry at the lack of emotional control as she perceives how "laden with self‑pity" (pg. 31) her voice sounds when arguing with Marvin in one instance. She cannot control how her "mouth speaks by itself, the words flowing from somewhere, some half hidden hurt" (pg. 68). After the denial and anger begin to fade, she attempts a short bargaining period where she wonders what if. She even tells God to bless her or not "just as You please" (pg. 307), but she would not beg. But even though she attempts to wrestle against the inevitable, there is always a constant reminder. She places her belief in herself only and faults other's credibility, such as Doctor Tappen's, to maintain the illusion now hanging by a flimsy thread. When Hagar realizes she cannot control or stop the process of old age, she becomes depressed and distant. When she hears about Silverthreads, she is "overcome with fear, the feelings one has when the ether mask goes on, when the mind cries out to the limbs, 'flail against the thing', but the limbs are already touched with lethargy, bound and lost" (pg.

German Barbarians :: essays research papers

Just outside the boundaries of the Roman empire of the first and second centuries, beyond the Rhine River, and occupying the area of Central Europe of what is today Germany, lived the tribes of the Germanic people. In Germania, the Roman historian Cornelius Tacitus gave an account of the lifestyles and organization of these peculiar barbarians. These descendants of modern Germans proved peculiar in that they adopted many qualities typical of barbaric cultures, yet they simultaneously practiced virtues more befitting of advanced civilizations, values more ethical than even the Roman empire of the time. The German warriors had a rigid code that defined how to live honorable lives and shameful acts to avoid committing, and the warriors also adhered to strict tradition in their relationship with their king or chief.   Ã‚  Ã‚  Ã‚  Ã‚  The climate of Germany suited the warriors well. The combination of â€Å"wild scenery and harsh climate† (Tacitus, Germania) had given the barbarians an inherent endurance towards cold and hunger over time. To cope with their surroundings, the warriors had developed powerful physiques, yet their abundant resources of strength and stamina proved not to be a source of pleasure for them, for the warriors had â€Å"no fondness for feats of endurance or for hard work† (Tacitus, Germania). In earthly matters, Germany’s apparent lack of precious metals made the warriors quite utilitarian in regards to physical possession. They preferred silver to gold, as silver could be more easily fashioned into useful objects. Only the tribes of warriors on the borders of the Roman empire recognized gold and silver as trading commodities, while the ‘backwoods’ tribes traded through the simple practice of barter, yielding one item in exchange for anot her (Tacitus, Germania).   Ã‚  Ã‚  Ã‚  Ã‚  The Germanic tribes were by no means idle people. Not content with the quietness characteristic of daily lives built on routine, â€Å"for rest is unwelcome to the race† (Tacitus, Germania), the tribes warred with their neighbors. In most cases, the tribes did not engage in voluntarily combat to gain or defend land or to right some alleged wrong against them; they mostly fought for two reasons. They first believed that it was easier to distinguish one’s self in the uncertainty of war, rather than in the predictability of routine. So war became a way for the barbarians to prove their honor, or sometimes expose their shame, as the abandonment of the shield during combat was â€Å"the height of disgrace† (Tacitus, Germania).

Plato’s and Aristotle’s Views on Knowledge

Plato and Aristotle view knowledge and the process whereby it is obtained. They both point out that many epistemological concepts which they believe where knowledge comes from and what it is actually. Most of them have been astonished me in certain ways, but I found that rationalism and â€Å"wisdom consists in knowing the cause which made a material thing to be what it is† make the most sense to me regarding the nature of knowledge. As the following, we will discuss about why these two philosophical viewpoints are superior and the others are inferior. Aristotle believes that sensory perception of material objects is knowledge and he says, â€Å"Our senses begin the process of finding the answer, because they are physically close to our minds. † However, sensations and feelings are very subjective, and the results of sensation vary from person to person and even within the same person, depending on the circumstances. What to one person is cold might be warm to another, one person may be more fatigued in the afternoon than in the morning, so that his or her perceptions may temporarily less accurate. Therefore one cannot claim that sensations provide sure knowledge for human beings. | On the other hand, Aristotle sustains that the perceptions of the senses form the foundation which leads to true knowledge. The senses â€Å"give the most authoritative knowledge of particulars† (individual material objects). The senses, especially sight, â€Å"make us know and bring to light many differences between things. † The senses thus provide a foundation that will ensure that human knowledge is true or accurate. Back and forth, we have already discussed that sensations cannot provide true knowledge for humans because of subjectivity, as in this case, this is not necessarily that perceptions of senses form the foundation which leads to true knowledge for humans. Plato believes that innate knowledge of eternal Forms that exist separately from material objects is true knowledge because innate knowledge does not require that the mind interact with the external world in order to be apprehended. It is present in the mind at birth, for it is God given, and has always been resident in the mind. Nevertheless, how does one know there is a God? For all we know, the existence of god cannot be proven by scientific methods, and this is for certain. In this case, how can humans get knowledge from god or gods? Therefore, innate knowledge should not be viewed as the origin of knowledge nor to help one to obtain true knowledge. For Aristotle's substance, it states that when one knows the substance (matter and form) or essential nature of a material object, one knows the first cause that made it to be what it is. This knowledge is true wisdom and is therefore true knowledge. I felt this philosophical viewpoint when I first saw it; however, this knowledge begins in sensory perception. Stated in premise, sensations and feelings cannot assist individuals to acquire true knowledge. For this reason, I do not fall in this epistemological concept afterwards. Moreover, a syllogism also cannot help one to acquire human knowledge. To Aristotle, these universal ideas are self-evident. The mind, having received appropriate sensory input, immediately sees that they are true. Although premises are formed as the result of inductive reasoning, it is based on sensory perception. Consequently, human beings cannot acquire knowledge by a syllogism. I personally fall with rationalism and wisdom lead us to attain knowledge. Plato and Aristotle both believe that thinking, defined as true opinion supported by rational explanation is true knowledge; however, Plato is a rationalist but Aristotle is not. Plato thinks that the external world can be obtained proceeding from the inside out. Thus, the foundation of true knowledge for the rationalists is that it originates in the faculty of reason. Furthermore, reason has the capacity to discover ideas or beliefs independently of the senses. These ideas or beliefs are self-validating and therefore have the status of knowledge because the rational faculty, which has discovered them, is the most accurate of the means by which human beings obtain knowledge. In Plato's Theaetetus, he says, â€Å"Any one forms the true opinion of anything without rational explanation, you may say that his mind is truly exercised, but has no knowledge. † This is quite true that when one can state a true opinion supported by a rational explanation, one's opinion constitutes knowledge, since perceptions of senses are excluding in this case. Moreover, a rational explanation does not contain any subjectivity, it is an objective entity for humans to understand true knowledge. For this reason, I fall with rationalism and believe it is a superior philosophical viewpoint about the nature of knowledge. Aristotle sustains that wisdom consists in knowing the cause which made a material thing to be what it is. For Aristotle, wise people know more than just what something is; they also know why it is what it is, or what causes it to be what it is. People with wisdom, for instance, a master worker understand not only that fire is hot, but also know why it is hot. Those with experience only, who do not know why something works in a certain manner, cannot teach. Say physicians understand that there is a relationship between the medical condition of this class of patients and the ingredients in this particular drug. They are then motivated to learn why the drug works on these people, or what causes it to be more effective with this group of patients than with others. In achieving this knowledge, one achieves wisdom. Once the physicians found out what causes the drug works, it will increase the confidence of other physicians to use it with similar patients of their own. If they just used it because it â€Å"works,† they might be more hesitant. Knowing why it works makes them feel more certain that it will be helpful. Moreover, by understanding how the ingredients work, another researcher might find another use for the drug on a related but different medical infirmity. Thus, the ability to teach something is important to one because it implies that the person who teaches has knowledge. In these cases, I believe wisdom is the ability to teach something to someone and it also contains a path for one to acquire true knowledge, therefore, it is also a superior philosophical viewpoint for individual to understand true knowledge. In my own life, I believe that one's knowledge is taught by parents, teachers, peers, and culture, and this is the reason for humans to have education. Our knowledge is received from the earlier generation to the next generation and so on. When I was a kid, I did not know why I had acne at that time. Now I am a teen, I know that during adolescence, hormones called androgens become active and stimulate oil glands in one's skin, increasing oil production. This, in turn, clogs pores, causing pimples and blackheads. I am educated in school and I understand the causes of acne now. In this case, I have true knowledge about what acne is and the causes of it because I have the ability to teach someone about acne, and it constitutes wisdom. This example fits in Aristotle's thought which wisdom consists in knowing the cause which made a material thing to be what it is, and therefore, the origin of knowledge. On the other hand, a study states that sunlight can prevent some types of cancer because vitamin D is manufactured in the skin when it is exposed to sunlight and it is this vitamin that may have a protective effect against certain cancers by preventing the overproduction of cells. In this case, a true opinion is supported by a rational explanation, and this study can help one to acquire knowledge because the study itself is knowledge. In this essay, we have examined different epistemological concepts of Plato and Aristotle about what knowledge is and the process whereby it is obtained. Since sensations are subjective, many of their philosophical viewpoints have been objected. Rationalism and â€Å"wisdom consists in knowing the cause which made a material thing to be what it is† make the most sense to me because they are not perceived by sensations, and they can be observed in our daily lives. Those are the reasons that I found these two concepts are superior to others.

Haemochromatosis

In medicine, Iron overload Indicates accumulation of iron In the body from any cause. The most important causes are hereditary haemochromatosis, a genetic disorder. and transfusional Iron overload, which can result from repeated blood transfusion. Terminology Haemochromatosis or haemoslderosls Historically, the term haemochromatosis was initially used to refer to what is now more specifically called haemochromatosis type 1 . Currently, haemochromatosis Is mostly defined as iron overload with a hereditary/primary cause, or originating from a metabolic disorder.However, the term is currently also used more broadly to refer o any form of Iron overload, thus requiring specification of the cause, for example, hereditary haemochromatosis. Hereditary haemochromatosis is an autosomal recessive disorder with estimated prevalence In the population of 1 In 200 among patients with European ancestry, with lower incidence in other ethnic groups. The gene responsible for hereditary haemochromatosis is located on chromosome 6; the majority of hereditary haemochromatosis patients have mutations in this HFE gene.Hereditary haemochromatosis Is characterized by an accelerated rate of Intestinal iron absorption and progressive iron deposition in various tissues that typically egins to be expressed in the third to fifth decades of life, but may occur In children. The most common presentation is hepatic cirrhosis in combination with hypopituitarism, cardiomyopathy, diabetes, arthritis, or hyperpigmentation. Because of the severe sequelae of this disorder if left untreated, and recognizing that treatment is relatively simple, early diagnosis before symptoms or signs appear is Important.In general, the term haemoslderosls Is used to Indicate the pathological effect of iron accumulation in any given organ, which mainly occurs in the form of haemoslderln. Sometimes, the simpler term siderosls Is used Instead. Other definitions distinguishing haemochromatosis or haemosiderosis that are oc casionally used include: Haemosiderosis Is haemochromatosis caused by excessive blood transfusions, that is, haemosiderosis is a form of secondary haemochromatosis.Haemoslderosls is haemoslderln deposition within cells, while haemochromatosis Is haemosiderin within cells and interstitium. Haemosiderosis is iron overload that does not cause tissue damage, while haemochromatosis does. Haemosiderosis Is arbitrarily differentiated from haemochromatosis by the reversible nature of the iron accumulation In the reticuloendothelial system. Clinical presentation Organs commonly affected by haemochromatosis are the liver, heart, and endocrine glands.Haemochromatosis may present with the following clinical syndromes: Cirrhosis of the liver Diabetes due to pancreatic islet cell failure Cardiomyopathy Arthritis Testicular failure Tanning of the skin Joint pain and bone pain 1 OF3 causes The causes can be distinguished between primary cases and less frequent secondary cases . People of Celtic, Br itish, and Scandinavian origin have a particularly high incidence of whom about 10% are carriers of the gene and 1% sufferers from the condition.Primary haemochromatosis The fact that most cases of haemochromatosis were inherited was well known for most of the 20th century, though they were incorrectly assumed to depend on a single gene. The overwhelming majority actually depend on mutations of the HFE gene discovered in 1996, but since then others have been discovered and sometimes are grouped together as â€Å"non-classical hereditary haemochromatosis†, â€Å"non-HFE related hereditary haemochromatosis†, or â€Å"non-HFE haemochromatosis†. Most types of hereditary haemochromatosis have autosomal recessive inheritance, while type 4 has autosomal dominant inheritance.Secondary haemochromatosis Severe chronic haemolysis of any cause, including intravascular haemolysis and ineffective erythropoiesis Multiple frequent blood transfusions, which are usually needed ei ther by individuals with hereditary anaemias or by older patients with severe acquired anaemias such as in myelodysplastic syndromes Excess parenteral iron supplements, such as what can acutely happen in iron poisoning Excess dietary iron Some disorders do not normally cause haemochromatosis on their own, but may do so in the presence of other predisposing factors.These include cirrhosis, teatohepatitis of any cause, porphyria cutanea tarda, prolonged haemodialysis, and post-portacaval shunting. Diagnosis There are several methods available for diagnosing and monitoring iron loading including: Serum ferritin Liver biopsy MRI Serum ferritin is a low-cost, readily available, and minimally invasive method for assessing body iron stores.However, the major problem with using it as an indicator of iron overload is that it can be elevated in a range of other medical conditions unrelated to iron levels including infection, inflammation, fever, liver disease, renal disease, and cancer. Also, total iron binding capacity may be low, but can also be normal. The standard of practice in diagnosis of haemochromatosis was recently reviewed by Pietrangelo. has been extensively validated. More than 11,000 FerriScans have now been conducted in over 120 medical centres across 25 countries.FerriScan is now specifically recommended as a method to measure liver iron concentrations in clinical practice guidelines for thalassaemias, sickle cell disease myelodysplastic syndrome and hereditary haemochromatosis. Family members of those diagnosed with primary haemochromatosis may be advised to be screened genetically to etermine if they are a carrier or if they could develop the disease. This can allow preventative measures to be taken. Prognosis A third of those untreated develop hepatocellular carcinoma.

Homemade Lava Lamp Essay

My science project is on the No Light Lava Lamp. I will record what happens when I mix vegetable oil and water in an empty water bottle. Most materials are classified into two different categories in relationship to the way they mix water. Hydrophobic substances are chemically unable to mix with water (the word hydrophobic means â€Å"water-fearing†). Hydrophilic (meaning â€Å"water-loving†) substances, can easily dissolve in water. In addition to the density difference, the reason that you will always see a distinct oil layer above the water layer is because of oil’s hydrophobic nature. Vegetable oil is a fatty substance obtained from certain plants. Manufactures obtain most vegetable oils from seeds and fruits. Most of these oils are liquids, but a few including cocoa butter, coconut oil, and palm oil are solids at room temperature. Water is the most common substance on Earth’s surface. It also covers then seventy% of the Earth’s surface area. It fills the oceans, rivers, and lakes and it’s in the ground air we breathe. Water is also everywhere. When you put the water in then put the vegetable oil in the jar the vegetable oil will float straight to the top because the vegetable oil is more dense then the water. Water and vegetable oil are like magnet’s that don’t like to stick to each other. If you shake the water and vegetable oil hard then it will get mixed up. When you put the salt in the bottle it will look like it’s going to stay at the top, but it will float to the bottom. When you put the cap on while some of the gases are still forming the lid will come off and you would have to clean up the mess and the bottle will start to break in half. Salt is a very small mineral, and can be used in many different foods, and it also has been used in ancient times. Salt also consists of the elements such as sodium and chloride. Salt also has a nickname the nickname is Halite. Halite or salt usually forms clear crystals that are almost shaped like cubes or circles. When salt is put in with ice the ice point is lowered. Salt is also used in a wide range of other products those products include ceramic glazes, livestock weed, medicines, oil refining, and water softening. Trucks spread salt by driving on highways during the winter to melt snow and ice. Twenty percent of salt is consumed in the United States for the deicing.  Seawater consists about two point five percent salt and about one percent other minerals in the water, mostly compounds of calcium, potassium, and magnesium.
