Rebuttal Argument - Essay Example Wild animals still entail the intrinsic trait of being unsecure. Therefore, people ought to vision beyond their passions and seek to secure themselves. Another reason for not legalizing the taming of exotic animals is that of common sense (USA Today). Wild animals are meant to be as such. Therefore, people should cage normal pets as opposed to the exotic ones. This is because there are animals designated to be pets and others meant to stay in the natural stay. This general sense is what those keeping wild animals lack. In addition, wild animals can never be pets because of passion for the exotic animal. This refers to the verity that certain people take to mistreating the exotic animals. This happens when they fail to bestow their liberty of nature. Moreover, wild animals thrive in conditions with provisions of nature. Therefore, when someone takes to mistreating the animals, this depicts that they entail no fairness. Opinion countering that of the editorial is that there are exceedingly low chances of deaths caused by exotic animals. For instance, statistics prove that only 3.25 Percent of people become executed by exotic animals (USA Today). Therefore, wild animals depict exceedingly limited risks pertaining to people’s safety. There are no explanations as to why people should evade exotic animals becoming their pets. Another reason is that having wild animals as pets eradicates strain on the natural populace (USA Today). This explains that competition among wild animals becomes exceedingly negligible. Therefore, resources become sufficient for the other masses. On the contrary, tamed animals are availed with necessities by the owner. This is ensures that natural endowments are ample for animals. According to The Humane Society of the United States, another reason is that exotic populace acts as a backing for extinction of the wild life. This means that in events where wild animals become rare, the tamed ones save the situation.

Why Internet Privacy Matters to Consumer Essay Example | Topics and Well Written Essays - 500 words

Why Internet Privacy Matters to Consumer - Essay Example As Cronin points out there is billions of customer data existing on computers across the world today, including bank accounts, credit card accounts, mortgage information, retirement fund details, medical claims and much more, and 'the web seamlessly links it all together' (Cronin, 1). Search Engines are a great mine of information. Privacy concerns range from popular search engines like Google and Yahoo which track IP addresses, time of search and search details. When search history, registration details and email details are taken together, you can have a comprehensive personal profile of any user. Cronin in her essay contends that many users 'are not aware that their online behavior is so readily recorded and analyzed' (Cronin, 2). Legal bodies in many countries have addressed the privacy issues, though this has not translated to new legislation. For example, a body in Norway has stated that Google's retaining for information for 18-24 months is too long a duration. Cronin argues that 'unless there is some external pressure to place limits on how much information is collected, or how it is being used, it seems that data mining practice will be fine tuned and expanded' (Cronin, 3). E-commerce sites command personal information including credit card information and purchase history.

Participation in higher education and women empowerment

Participation in higher education and women empowerment In the research conducted by Samina Malik and Kathy Courtney the finding from Maliks 2005 study was summarized. It was from his study that the wanted to investigate that to what extent does women empowerment was dependant on the gaining of higher education by women. In the research the importance of the prevailing culture and norms on women empowerment was also highlighted as they play a key role in preventing women from claiming the rights that they have been given by law which includes having equal rights to education. As Pakistan is a developing country it has been rated s the nation with the widest gender gap and discrimination against women (UNICEF 2006). The united nations population information network gave the understanding that women empowerment has five major components, which include women sense of self-worth, their right to have and to determine choices, their right to have access to opportunities and resources, their right to have power to control their own lives, both within and outside the home, their ability to influence the direction of social changes to create a more social and economic order, nationally and internationally,(POPIN n.d) However it has come to notice that overall the girls and women are at disadvantage and the movement to bring about any change in their position or their standard of living has failed. Forming a conclusion from the research it has been proven that the attainment of higher education in particular is accepted as a means for social change. The participation in education has many advantages for the women one of the most important one being economic independence. As agreed upon by Iram, samiullah, tanveer, bedi-uz-zaman, shujaat and Ali women empowerment is a social phenomenon. Women in Pakistan are subject to very little participation in the economic sphere of life. Usually they are either underpaid or unpaid workers in the agricultural background. I their research the authors also subject that women empowerment can be measured based on their participation in politics. However the most important aspect being catered to in their study is the impact of male youths views on women empowerment. Since Pakistan is clearly a male dominated society and the views of the male segment plays either a supportive or opposing role towards women empowerment. It was concluded after the study that the prevailing view of women empowerment from the eyes of the male youth has different aspects of acceptance. Regarding ownership of property, vote casting and registration the response was fairly positive. It was also positive towards equal job opportunities, traini ng program and membership of union and organization but political participation and participation in public protests and political campaigns was a negative. Overall however the attitude of youth towards women empowerment was considered a positive but the family practice of the positive attitude was very limited which may be due to the parents background and quality of education. According to Malik hassaan the reason for women being neglected and lookdown upon may lie in some common factors which stem from the history of the country. The social norms and cultures and the menace of poverty have been put down on the shoulders of the women of this country since its birth. The idea proposed that economic development to actual take place in a nation requires the participation of the entire citizens of the nation by Malik is crucial to this country. The concept highlighted is the importance of poverty and government intervention in the developing worlds. The history bearded by the developing nations plays an important part also in another study relevant to this is by Ndrit. Assie-Lumumba regarding the women and empowerment in Africa. The idea being discussed by both the authors lie in the fact that the nations having participated in many international betterment and development programs and organizations the implementation of laws pro-women have been poor due to the history of poverty and culture prevailing in these nations. The insignificant intervention of the government and the lack of positive will towards this idea not only hinder the social well-being but also the e economic wellbeing of these developing nations. As Assie-lumumba explains the participation of women I higher education and universities are extremely low due to which any research conducted from these institutions dont show the actual picture. Although the educational system has been taken from the wests example, the persisting lack of participation by the female sector cannot be ignored. The reason for the lack of involvement doesnt however lie solely with the historic practices but also by the recent practices which have stemmed out from the historic practices in essence strengthening them. The issue being that without access to primary and secondary education the female masses cannot have the opportunity to advance into higher education. The practice of not allowing equal opportunity at the initial levels of education is a major hindrance for the women of Africa. The other main issue discussed in the study relates to the lack of power to have time, equipment and finances being allocated to women in the African society. This also raises the gender gap and in essence reduces the ability of women to participate in education. The absence of proper policies and implementation of these policies thus result in the discriminatory policies regarding education and women in the African continent. The idea that most of the conclusive research done in the developing countries result from the research conducted in the university setting, the absence of women form these institutions result in a lack of information and authentic research. The formation of policies also rest on the information collected therefore the lack of information subsequently result in improper and insufficient efforts being conducted in the way to women empowerment. Lumumba also rightly concludes based on assessment that the role of the researchers are highly crucial in the forward view of the continent and it is their responsibility to interrogate all analyze all the social sectors to finally come up with conclusions. Therefore educating the female masses of the nation is essential to not just economic wellbeing and eradication of poverty but also a healthier social standing of the nation. The same standing is put forth by Malik Hassan in his research that poverty and economic sustainability of Pakistan rests on the shoulders of policy makers and researchers. There is a crucial need for proper research and data availability and a dire need of the policy makers, the government to shape up reforms and implement them in the most efficient and effective manner as without this the nation will not be able to move from the developing category to the developed. The nuisance of poverty and the economic instability is directly related to the no participation of the entire nation towards there amputation. In his conclusion Malik also explains the importance of awareness amongst the citizens, capacity building of women, research and documentation on the achievements of women and advocacy for policy in political parties as essential and substantial requirements to overcome the structural obstacles and lack of awareness in the country. The importance of women participation in policy formulation and their representation at all levels of the government is necessary for the wellbeing and progress of Pakistan. Women empowerment is defined as a change I the context of a womens life that will enable her to lead a fulfilling human life, it being reflected both in external qualities and internal qualities (human development in south Asia (2000) as quoted by Mathew (2003). In the research by purusottam nayak and bidisha mahanta it is found that women of India, another developing nation, are relatively disempowered and given a lower status than their male counterparts. The existing of this gender gap exists basically with regards to education and employment. Different aspects of the study focused on different factors that were looked at by the researcher. These include women having the right to education and employment; domestic violence and say on spending their earnings; womens exposure to media and heir involvement in politics. After a clear view it was concluded that women were subject to unequal treatment b the male dominating society. Dr suvarna sen and ishita mukherjee also in their study look at the prevailing trends of role of women in India and they also examine the employment levels, wages, literacy and school enrolment; their participation in politics and personal health issues. They also suggest from their study that women are being subject to socio-economic biases which in retrospect affect their status in society. The most alarming find from both these studies show the acceptance of this unequal and bias treatment by the women in general. All these factors are either the result of governments shift from raising actual awareness and or implementation of policies structured for women empowerment. The major role of higher education and employment is the conclusive factor in both the studies. It has been seen in Dr surarna sen and ishita mukherjees finding that rising of awareness and education are the only forums which may result in ability to combat these practices. The entire idea of is also supported by purusottam nayak and bidisha mahanta in their findings that access to education and employment are the only enabling factors to empowerment. However in similarity the studies also conclude that the hindrance towards this goal is mainly due to the lack of government support. The idea that government does not support encouragingly the institutions set to formulate policies regarding the bettermen t of the female population and also doesnt take steps in helping in the implementation of these policies for proper coverage and benefits. The idea of empowerment if not wholly supported by the mass of male population and the authoritarian of the country, cannot flourish and bloom. The presence of education plays a pivotal role for women in helping them realize and understand their rights and their rewards. Without which they may not be able to come out of the current situation and remain to believe themselves subjugate to domestic vigilance and gender bias. Another study conducted by purusottam nayak and bidisha mahanta examines the impact of women empowerment in Assam. In this study as well the women empowerment quotient is judged on the basis of indicators such as education, employment, household decision making power, financial autonomy, and freedom of movement, exposure to media, political participation and experience of domestic violence. Assam is one of the states of India and the largest state in the region of North east India on basis of population. Although it is free from a lot of social evils like dowry, sati, female feticide and infanticides it is still ranked very low in the scale of female empowerment. There is a wide gender gap in the state which is even not found in other comparable states in India. the study concludes that the development of the state is being affected by the widening inequality in gender and that the development process is not gender neutral as women are subject to lower status as even when compared to the rest of the states in India. There does seem to be political involvement of the woman segment in the state however other than that the educational and employment status is very low. Also the access and reach over resources is very low as well. Meetika Srivastava In her study gives a profound view on women empowerment. She begins by explaining the importance of women in the society and their pivotal role in shaping the nations future as mothers, teachers etc. she also very clearly signifies the women rights that are considered under the act of humanitarian law worldwide. The basic human right that woman is entitled to live in dignity and esteem. Have freedom of want and freedom from fear just as her male counterparts. The importance of this equality has been underscored by its inclusion as one of the Millennium Development Goals. However she goes on to explain further that even though worldwide gender equality has been given an important stature it remains to a practically neglected avenue. Violence and discrimination is a very common practice however now economic discrimination has also joined in the list of inequalities which include health and education. Despite a lot of controversy and a lot of this agenda being raised by the international organizations, women are still more likely to be ill, poor, illiterate and tortured than men. Another important factor for empowerment measurement is the control of their own fertility. This aspect is so crucial that it is considered sometimes, as the benchmark for empowerment as said in the study that, when a woman can plan her family, she can plan the rest of her life. Srivastava 2009 Ms Srivastava is on the right path when she concludes by her study that women empowerment is a strong factor towards development. She explains further that despite the said progress that is made the female segment of the society is the most neglected segment as yet. Especially with regards to basic health and education they seem to be suffering magnanimously. she goes on to close with the fact that no kind of social empowerment, legal empowerment or economic empowerment may be able to take place without focusing on women empowerment. In his study of women empowerment in India, Mr. gagandeep kaur explains that the empowerment assumed to be prevalent in the society where women are known in literature and religious scrolls as devis or shakti is all a faà §ade. It doesnt exist and all the rights and privileges so called adhered to women in the Indian society are just on paper in ink and not in real life. He goes on to explain that the status of women cannot change by the mere idea of introducing the terms but it requires a complete change of metal setup which is deep rooted in not just the minds of the people but also of the woman herself. The biggest problem is that women are unaware of their own rights and what world of opportunities lies for them. Various efforts are being conducted by free lance NGOs, media and welfare organizations, but what is most important is the involvement of the government he says. Gary S Becker, William H J Hubbard and Kevin M Murphy follow on the research that they conducted regarding the worldwide boom in higher education with regard to women education. In their research they explain that there has been a high increase in the education of female and males around the globe. They d agree that citizen in developing nations and developed nations do get different share of education however according to new statistics there has been a substantial increase in both the worlds higher education trend. The most important factor that they have come to notice is that the research provides them with sufficient facts that the increase in higher education is due to women. In their research they provide a model of supply and demand in market for college educated workers. They also examine the effects of the costs of college education and difference in gender and also means and distribution of skills.

The Supernatural in Shakespeares Macbeth :: GCSE English Literature Coursework

The Supernatural in Macbeth Displays of supernatural activities were used throughout Macbeth, and evidence of this was brought out in the appearances of the three Witches. In Shakespeare's day, special effects were not used in his plays. Therefore, the dramatic performances and the suspenseful scenes were the fundamental qualities to making a great play. Shakespeare used the element of the unknown to evoke fear in the minds of his audience. By allowing the Witches to see into the future, it made Macbeth more suspenseful. With their prophecies about Macbeth?s future, they intrigue the audience to see if they are correct. The Witches were a symbol of evil, and Shakespeare uses this fear of the devil to give his plays an additional eerie and haunting effect. Shakespeare also used an evil character that can easily influence the main character in his stories, in this case, it was Lady Macbeth. It is essential that   Lady Macbeth and the three Witches create the plot of Macbeth. Without the Witches powers of forete lling the future and the evil persuasions of his wife, Lady Macbeth, Macbeth would have never become king.   Ã‚  Ã‚   The expression "weird sisters", used from the 1400's, means "Fatal sisters". The word "weird" or in Old English Wyrd was a noun meaning Fate. In Act 1, Scene 3, The three Witches describe themselves as fore-tellers of   destiny, and they all introduce themselves to Macbeth and Banquo as "The weird sisters, hand in hand". The appearance that the three Witches possess is that of pure evil. In the starting of the scene, each of the three Witches describe their wickedness with a proud manner. For example, when they asked the Second Witch where she had been, she replied, "Killing swine". This statement shows how the Witches enjoyed being devilish. The impression that the audience gets of Witches is that they are hideously evil. In Shakespeare's time, witches were believed to have supernatural powers, they could transform themselves into other shapes, usually animals. When the First Witch describes where she had been, she referred to sailing across the sea in a sieve and tra nsforming into a rat without a tail, But in a sieve I'll thither sail, and like a rat without a tail, I'll do, I'll do, and I'll do?. Witches were also believed to   fortunetellers. The three Witches prophecies in Macbeth, foreshadow later events in the play.

Acknowledging Female Stereotypes in Much Ado About Nothing Essay

Women in the Elizabethan age were extremely repressed and discriminated against. Most would not have gone to school or received any type of formal education. They were not allowed to vote, own property, or freely voice their opinions. They were seen as the property of a man, subject to his wants, needs, and not allowed to have their own; men held extremely stereotypical views of their female counterparts that helped them justify the way they treated them. Shakespeare exposes many of these injustices and biases in his stage plays, which are still commonly read and performed today. In Much Ado About Nothing, Claudio moves from seeing women (specifically Hero) as goddesses and wives to adulterers, and then back again to his original views. Claudio initially views Hero according to the established stereotypes, in Act 1, Scene 1 as property. When first speaking of Hero, he refers to her as the â€Å"daughter of Signor Leonato;† while this appears to be simply for identification purposes, he actually relinquishes the power of her name to her guardian (1. 1. 119). Instead of calling her by her given name, Hero, Claudio names her in relation to her more powerful male owner. He goes on to ask Benedick if she is a â€Å"modest young lady,† not wondering only if she is sweet, but if she is literally a virgin (1. 1. 121). A woman’s virginity was extremely valuable in Elizabethan England, and determined her worth as a potential wife. This outright inquiry into her purity foreshadows the later scandal surrounding it. Benedick asks Claudio if he would buy her, and Claudio responds with a seemingly noble hypothetical question: â€Å"Can the world buy such a jewel?† (1 1 134). While his question seems to imply that she is so valuable that the entire world’s money could not purchase her, it still perpetuates the stereotype that women are pieces of property, albeit very beautiful and expensive ones. Later in the same scene, Claudio demonstrates Elizabethan men’s views of women through Shakespeare’s thematic messages. He remarks that â€Å"in mine eye, [Hero] is the sweetest lady that ever I looked on† (1 1 139). This introduces a reoccurring theme of Much Ado About Nothing of seeing and perception. Here, and later on in the play, Claudio bases his opinions of Hero on her outward beauty and appearance of piety. In addition, the words â€Å"mine† and â€Å"I† stress the importance of Claudio himself, the important, powerful male in the situation. One notes Shakespeare’s wordplay in the pun implied when â€Å"eye† and â€Å"I† sound interchangeable when spoken aloud. Another theme surfaces in the use of the word â€Å"sworn† in line 144 of Act 1, Scene 1, whereby Claudio makes evident that his honor depends on people’s perception of him and, by proxy, his future wife, Hero. Also notable is the hope he expresses that Hero would â€Å"be [his] wife†, in that he uses language again pertaining to himself; where he could have wished that Hero would â€Å"marry him† or something similar, he instead wishes her to become his property. Claudio reveals that he has had an interest in Hero for a while before their present conversation about her. He admired her before he went away to war, but more pressing, important, masculine issues took his mind off her. This implies that matters of the heart were less valued by men than duty and honor, and that his current infatuation with Hero is sort of an afterthought, something to pursue as he is now bored. This distant, material admiration for Hero quickly turns to contempt when he thinks that Don Pedro has taken her for himself in Act 2, Scene 1. When Don John and Borachio tell him about his friend’s betrayal, Claudio seems to be angrier with Hero than with the man who stole his prospective bride. He claims â€Å"beauty is a witch, against whose charms faith meltheth into blood† (2 1 135-6). This demonstrates the stereotype that Elizabethan men held of women being easily turned to adulterers – it seems to be her evil beauty that lured Don Pedro into supposedly winning her over for his own. This is again an insult to Claudio’s pride; Don John and Borachio use forms of the word â€Å"swear† when recounting Don Pedro’s supposed conquest of Hero, calling to mind how Claudio swore to marry her in the first act. Claudio denounces Hero, and wishes Don Pedro â€Å"joy of her,† once again suggesting women to be objects of personal property, solely existing to fulfill the desires of man. When it is confirmed that Don Pedro was indeed just performing his friendly duties, Claudio instantly reverts to his view of Hero as a perfect, virginal, almost goddess-like potential wife. He says to Hero: â€Å"Lady, as you are mine, I am yours: I give away myself for you, and dote upon the exchange† (2 1 233-4). Claudio acknowledges that Hero is now his property, and as that is an accepted custom in Elizabethan England, it is therefore deemed heroic that he gives himself to her, as well. Using the word â€Å"exchange† suggests a formal transaction of property, which is what is really transpiring between Claudio and Leonato. Claudio expresses his anticipation for the wedding, as time moves slowly â€Å"till love have all his rites† (2 1 269-70); the two meanings of rites as the actual ceremony and rights as a husband provide insight into this. He feels a necessity for their union to be official, as legally marrying Hero will give him legal ownership of her, and her property. Though he claims to love her, his affection could ultimately be seen as a want of her dowry. Claudio shows his opinions of women in his comical description of Beatrice’s love for Benedick in Act 2, Scene 3. He describes her grief over her unrequited love in a ridiculous way, saying that she threw a savage fit. This implies Beatrice, and by extension all women, to be controlled and weakened by their emotions. Claudio says that Hero had told him that Beatrice would surely die if her situation with Benedick progresses in any direction, again poking fun at women’s irrationality. He suggests she wear herself out by talking to someone about her love, as though she were a small child throwing a temper tantrum. Like most men of his time, Claudio appears to believe that women’s perceived lack of control of their emotions made them less worthy of esteem. His view of women again turns cynical again when he receives news in Act 3, Scene 2 that leads him to believe that Hero has had an affair with another man. Don John uses the word â€Å"disloyal† to describe her actions, and Claudio repeats that word in outrage and confusion about this blow to his honor (3 2 76). Being â€Å"disloyal† seems worse than most other things, in that it has wounded Claudio’s pride and reputation. The prefix â€Å"dis† is extremely negative and poignant. He emphasizes that if he sees anything with his own eyes, he will believe these accusations. He describes the issue as â€Å"mischief strangely thwarting,† and extends that description to all women in general; here he shows that he has moved from seeing women as wives and goddesses to adulterers and shrews. At their wedding ceremony in Act 4, Scene 1, Claudio spitefully and ironically addresses Hero with all sorts of virginal, innocent, pure language like â€Å"maid† (4 1 19). He again describes her as property in calling her a â€Å"rich and precious gift,† yet this time it is with an air of contempt and scorn (4 1 23). Continuing the theme of perception and sight, he calls Hero â€Å"but the sign and semblance of her honor,† implying that she merely put on a facade of virginity and purity (4 1 28). He asks the attendees of the wedding and, by extension, the audience, to acknowledge that her innocence is merely a show. Claudio accuses her girlish blush to be truly that of guilt and shame. Where previously he has referred to Hero as a maid, here he calls her only â€Å"like† a maid; this literal comparison emphasizes his change of feeling toward her and her sex. He facetiously describes her as the goddess of chastity and the moon, Diana, and of an unopened flower bud – virgin in appearance only. Then he compares her to Venus, goddess of sexuality, and even to mindless beasts that act only on impulse and instinct. In the line â€Å"Marry that Hero, Hero itself can blot out Hero’s virtue,† he proclaims that women are the source of their own downfall (4 1 75). Where her outward appearance was that of a virtuous young lady, her perceived actions lead Claudio to believe her to be a whore. Although one could argue that Claudio’s view of women was that of all Elizabethan men, including Shakespeare himself, the development of Benedick’s opinions show that this is not true. He begins the play disliking the idea of marriage and especially marriage to Beatrice, yet, through the dramatic action, he learns to love and appreciate her for her previously detested intelligence and wit. Benedick learns to value women for the humans they are, and yet Claudio still sees them as property at the end of the play. This suggests that Shakespeare realizes that, although he can bring attention to the issue of gender equality in his works, he cannot expect the audience to fully accept his ideas. Claudio constantly moves between stereotypes in his views of women in this play: he alternatively sees Hero as wife, goddess, adulterer, and everything in between. Shakespeare’s specific word choice and themes revealed in Much Ado About Nothing provide insight into how women were actually thought of and treated in Elizabethan England, and how the author himself believed they should be. Today, the centuries-old fight for gender equality is far from over. But, like Shakespeare, we can hope that all women will eventually be respected as equals, like Beatrice.

Belonging Essay

Belonging is the finest thing in the world that knows how to belong to oneself. You have to belong to yourself before you belong to society. Belonging is a quite a hard concept, as you can argue that people who don’t want to belong actually â€Å"belong† to a group of people who don’t want to belong. But what is belonging? One idea is that you belong when you feel comfortable with people who have similar objectives, goals, and aims as you. But, as i realised while analysing a film in fact it’s for this unit, if you don’t feel comfortable with the group you believe you belong to, then even if you have the same goals for example cricket. Even though everyone’s goal is to win, should the team not befriend you, make you feel like you are excluded from the team, then you don’t really feel that you belong to the team so it’s basically what belonging is about. My first text is about a song by my island home by Christina Anu and how the singer portrays aspects of belonging through her song lyrics. Firstly she explores the idea that belonging to people or places shapes our identity and then she explores how the barriers which prevent belonging can create a need to belong. The song Island Home shares her perception that belonging to certain people or place creates our ideology of life and where we rightfully belong. We live by the sea and My home is Australia this use of language shows pride and belonging to Australia. This creates and brings belong into place where our perspective of belonging to be one of happiness. Belonging is evident in the song in the boat on the sea again, and I holding that long turtle spear, and I feel close to where it must be. The composer emphasises the point that her home must be by the sea because that’s where she is from and where she feels that she belongs, the pride of her belonging. We create our own identity from the feelings and affections we have with belonging to certain societies and their way of life. Inclusion and isolation demonstrates our personal identity which portrays who we are. Our perspectives and views are changed depending upon what we belong to. My home is Australia; we are a land bound by sea to show that Australia is a part of her which will never be lost is also shown as her the composer is from a native background (aboriginal). She emphasises on how her and land are one, and it is this affection that had shaped her identity. Belonging in the song My Island Home? which I find is people who had experienced belonging to a place or community. But the song conveys the composer as; these glimpses are obviously not enough to make you feel the same way real belonging makes others feel. The composer shows the barriers she has to overcome like modernisation, family and living far away from the place she belongs to and this belonging is felt by her. The composer shows the importance of belonging by using a reflection question to compare her life in the present time and when she belonged. Will this place ever satisfy me this shows how much she wants to belong again, which portrays her strong love for her place of belonging. The composer only reveals through her dreams how she feels towards belonging. Six years I have lived in the desert, every night i dreamt of the sea shows the identity of the composer since Australia is covered in desert lands ad this shows the connection she has with Australia through her. Ahhh already it has taken so long to type this up for you to read , hope you are bored because you have a lot more to read so stay awake and read it ahah. My second text is on Edward scissor hand by Tim Burton, I was actually going to Life of Pie by Ang Lee but it was quite tough to relate to belong so I went with Edward scissor hands plus I got a bit help my English teacher for this movie so it make my life a bit easier. At the beginning of the film we see that Edward lives alone in a gothic castle. He has been isolated in the castle for an indeterminate time. Below the castle is a small town a close knit community and barely visits the castle, not knowing that Edward lives there. Peg feels sorry for him and decides to take him back to live with her in the town. At first Edward is being treated well because he is a great novelty. No one has ever seen someone like him before and he quickly becomes a celebrity. He is embraced by the townspeople; they think he is very useful with his scissors (haircutting, gardening etc. ) one of the town women thinks he is sexy and tries to seduce him. He refuses and runs away. This incident becomes the catalyst for Edwards’s rejection and alienation from the community. Edwards’s personality consists of innocent, naive, limited social skills, very gentle and very experienced at relationships with people, no idea of sex, manners etc. Other than what his creator taught him from books. He is very trusting until he finds himself he victim of a setup. After things become worse, Edward finds he is a victim and cannot remain in the community. Techniques used to convey the context relevant to belonging is that Edwards’s clothes and appearance is a complete contrast to town’s people. When he first arrives Peg him clothes to wear which he puts on over his own costume. This helps him develop a sense of belonging to the family and the community and reduces his difference to the townspeople. However the fact that he doesn’t remove his clothes indicates that he wants to maintain his identity. Later in the film he becomes angry and feelings of rejection and alienation by the town cause him to rip off. Music is used in a number of ways to show Edwards innocence and purity. His character is linked to Kims in the way music and lighting are used, the haunting they’re music, together with soft/bright lighting plus show plus the slow motion of the camera reinforces the innocence and the nature of their love for each other. At the end of the film, when it becomes impossible for Kim and Edward to belong to each other in a proper relationship. He goes back into the castle and she to the town. All though they cannot belong together physically they will always belong together emotionally. This is shown at the end of the film as Edward continues to make snow from the ice and flashback to the narrator at the child’s bedside. Alright you only got a bit more reading for go so sit back and read the rest and tell me how I went. For my third text I have chosen the picture the island by Armin greder. The picture book, The Island portrays belonging as impossible if there is an ignorant and fearful dominant culture. The book portrays to the responder into almost alienation and new comer into a strongly built and well organized society. The alien is portrayed as thin and white-white and unclothed showing that the new comer is an empty canvas to be painted opinions onto. The new comer is also thin and innocent looking showing how the character is reliant on acceptance to survive. Whilst the dominant society is given the appearance of large, over bearing, they are always portrayed as a collective group portraying their dominance. They are in black clothing, they all appear to look the same- again representing there collectiveness, and they are holding pitch forks portraying their feelings towards the new comer unwelcomed. The dominant society belong together they appear to look the same, and have much of the same views, they have collectively created a community that are dependent on each other and there likeness. The society is well established and fearful of anything that will imbalance its structure and that is different from their social, cultural and historical similarities. The new being does not offer any change, it does not do anything to radicalize the community but just its presence of being different offers physiological fear to the dominant society. The book demonstrates the effect of fear, what it does to a community and the object being feared. Through fear of this unknown the community alienated the unknown, trying to forget its existence when this did not work the community they contemplated integrating the being. But the overbearing fear of the effect the being would have on their system led them to cast out the different being. The being that was submitted to the dominant cultures fear was treated as inferior, become the dominant society did not want the unknown to belong they create a barrier around themselves in fear of the unknown and it defining themselves as exclusive. Because the dominant society was afraid of the unknown they showed ignorance and a lack of open thinking which creates difficulties to them from acceptance and understanding of anything other than their own people. Therefore Belonging is a way of life which characterises us humans and creates our individuality. Due to the complex and abstract nature of the concept of belonging, a true sense of belonging can be found in different circumstances for different people. As each individual has their own desires, needs and values, they find their place in the world and a genuine sense of belonging in various avenues. Many individuals find the strongest sense of belonging through relationships, due to the fact that by nature these connections fulfil the human need for social interaction and enrich the lives of the persons involved.

Tsunamis essays

Tsunamis essays All around the world natural disasters such as earthquakes, volcanoes, tornadoes, and hurricanes, are waiting to strike like a time bomb waiting to explode. Once unleashed, these natural disasters could become deadly. One of natures tremendous natural disasters is the great waves of the mighty ocean. In the past people referred to them as tidal waves a name that is misleading because these great waves are not related to the tides in any way. The Japanese, who have felt the waves destructive power for many generations, gave them the name Tsunami pronounced soo-nahmee. The word Tsunami means harbor wave which references the giant waves ability to penetrate the protected harbors along Japans coast (Koenig, Science). Although these natural disasters are not as common as others, people need to be aware that Tsunamis can be very devastating and destructive, more so than tornados or other storms. People need to educate themselves on how tsunamis are formed, the destruction they ca n cause, and the warning and support centers that have been established before the clock runs out and its too late. Before one can truly understand the devastation and destruction these natural disasters can cause, one must first understand what causes tsunamis and how they are formed. There are many causes of tsunamis such as landslides, volcanoes, eruptions, and explosions, but the most common cause are earthquakes. The relationship between earthquakes and tsunamis has been known for more than 2,000 years ever since the Greek historian Thucydides connected an Aegean Tsunami in 426 B.C. to the quake that preceded it (Koenig, Science). However, in order for a disturbance to generate a tsunami, the disturbance must occur underneath or near the ocean, be extremely large, and cause movement in the seafloor. When earthquakes occur a plate usually plunges dow...

Analysis - Article Example The researchers justified the use of qualitative method because they asserted that certain dimensions of nursing errors remain unexplored. They did not explain the philosophical underpinnings of their research method, although they highlighted that they believe that there is enough confusion, ambiguity, and diversity on the definitions and perceptions of medical errors, which warrant the need for more contextual exploration on critical care nursing’s understanding of nursing errors in particular. The researchers explained their purpose sufficiently when they stated that they aimed to explore how critical care nurses perceive nursing error and its causes. They believe that their study is important in providing a specific perspective on what constitutes nursing errors and what factors may cause them. To collect data, the researchers used the qualitative content analysis method which generally uses interviews and other qualitative data collection methods and content analysis in conducting the research. The method is compatible with the purpose of the research because the research necessitates exploratory questions that are more open-ended than close-ended, since the researchers want to know the actual range of perceptions of critical care nurses, and not to test specific models or theories about nursing errors. Moreover, the method adequately addresses the phenomenon of interest since the researchers are interested in knowing what the target subjects think about nursing errors and its causes, so they need to ask open-ended questions to collect answers in an exhaustive manner. In addition, the researchers completed the study using the qualitative content analysis method because they conducted deep, semi-structured interviews that are based on general open-ended questions which can encourage participants to think deeply and extensively about their

Sec in Southwestt Asia Essay Example | Topics and Well Written Essays - 1500 words

Sec in Southwestt Asia - Essay Example This requires an urgent ceasefire between the two countries to restore good relations. As earlier stated, the conflict between India and Pakistan has impacted on the entire South Asian region. The United States is one of the many countries that have been concerned with the war making it a priority agenda (Lamb 1966, p.12). For instance, during the handing over of the presidency from Clinton to George Walker Bush, the former advised Bush that the persistent antagonism between India and Pakistan needed to prioritized because of the dangers posed by the nuclear capabilities of the two countries (Misra 2010, p.32). The objective of this paper is to explore the reasons for the continued hostility between India and Pakistan relations. It will also discuss steps that can be taken to develop and sustain cordial relations between the two countries. Indo-Pak conflict has been a long-standing political conflict that began in 1947 immediately after independence (Brines 1968, p.35). The war has s ince persisted with the two countries being suspicious of each other. Report indicates that the two countries have fought three deadly wars since independent because of the continued friction between the two countries (Raja 2013). ... The war ended in 1949 following a ceasefire leaving the state of Kashmir split into two with India being handed two-thirds of the eastern side of Kashmir (Sareen 2012). Pakistan, on the other hand, gained control of the remaining third of the western Kashmir. However, due to continued hostility over Kashmir, the two countries again engaged each other in war in 1965, with the war ending in a military stalemate with the division of Kashmir remaining unchanged. Ever since, there has been a disagreement over which county owns Kashmir, with both countries claiming rightful ownership. According to Pakistan, Kashmir is the â€Å"K† in Pakistan- a Muslim dominated territory that according to the two-nation theory should rightfully belong to Islam (Sareen 2012). In this regard, Pakistan claims that, as a Muslim majority in Kashmir, the territory should have rightfully formed part of Pakistan at the time of partition in 1947. Therefore, merging Kashmir with Pakistan, according to Pakist anis is termed as â€Å"unfinished business of Partition,† which they intend to ensure, becomes fulfilled (Karim 1996, p.22). Indians, on the other hand, opposes this claim arguing that their possession of Kashmir province is a clear demonstration that Muslim dominated state can exist in India. This according to Indians is a good example of how India embraces people from different faiths. As a result, Indians believe that relinquishing Kashmir territory to Pakistan will threaten Indian unity. Some Indians also believe that additional partitioning of Kashmir according to religion would not do any good, but reopen the status of Muslim as Indian citizens and remind people of the wounds caused by the partition. This struggle has been persistent with both countries claiming

Thailand the Struggle for Success Essay Example | Topics and Well Written Essays - 1250 words

Thailand the Struggle for Success - Essay Example The import substitution policy was then replaced in the mid-1970s with the policies to boost exports. The impact of this shift in policy meant that not only Thailand now had a strong agrarian and industrialized economy but it also diversified in a sense that its economic structure became export-led which had a portfolio as diversified that it included textiles, electronics, chemicals, iron and steel, and minerals. One of the reasons for this diversity in the portfolio was the abundance of labor and natural resources. Thus, Thailand took complete advantage of globalization and its economy reported a growth in its average real GDP of 6.6% from 1960 to 1996 (The Brooker Plc p.8-9). This growth is the average growth rate in these years, there were also years in which Thailand witnessed exponential growth rate in terms of GDP and until 1997, Thailand was all set become the regional hub of the business and commerce activities in the region. Before 1997 Thailand implemented a policy of fixed exchange rate. Its exchange rate was pegged against the dollar. This effectively reduced the transaction costs attached to the inflow and outflow of investments. This obviously resulted in speedy growth as a result of the foreign direct investment. Unfortunately, the lack of foresight and anticipation on the part of Thai government led to the settlement of an economy which was heavily dependent on this direct investment. This policy saw its negative ambiance when in 1997 the investors lost confidence in the recovery of their investments and thus began to keep a check on their investments. The trigger down effect led to heavy speculations against baht and the local investors sold baht and bought more dollars. This caused the capital outflows from the country. But the real impact was felt when the government decided to float the exchange rate.

LLM EC Competition law Essay Example | Topics and Well Written Essays - 750 words

LLM EC Competition law - Essay Example Within the UK Articles 81 and 82 EC have been incorporated into the Competition Act 1998 (CA). The aim of these articles and the CA is to prohibit agreements, business practices and behaviors that have, or are intended to have, a damaging effect on competition in the UK (in the EU for the EC Articles).1 Article 81 prohibits any dealings that will distort competition within the EU, which includes any agreement from insider trading through to companies discriminating to supply goods or services on the basis of preferential businesses. The sale and supply of goods and services should be open to all members of the class that the company deals with. Also the sale of goods and services should be based on fair and open grounds, examples that the Office of Fair Trading and the EC use to illustrate anti-competitive agreements, in addition to cartels, include: The basis that the EC has used to identify what grounds are anti-competitive can arguably be determined as not economic, but more socially based. On economic grounds could such agreements as shown above not be a way to create a more competitive market, because if the present competitors agree to limit output does this not open the door for new businesses to open up in order for supply to meet the demand. Therefore it is questionable whether the current system of law is really dealing with what is economically competitive on economic grounds3. This is even more apparent with Article 82 EC, which deals with identifying what equates to abusive behavior by a company in respect to EC competition law. In order to be abusive under the company must be in a dominant position, which raises a question on the fairness of this article because if a company is not in a dominant position why is it not abusive This seems to be more of a social rather than an economic factor, because it means that if you are NOT a powerful and dominant company you can do as you wish.4 This illustrates that the grounds that EC law is determining on abuse in fact favors one sector of the economy over others, i.e. the underdogs. Is this not an abuse of competition law, because in certain instances dominant companies are a natural part of the industry's landscape, e.g. water, natural resources and fuel. This indicates that the current approach to determining a breach of competition law is in fact ironically a breach itself. The definition of dominance comes from the cases of United Brands5 and Hoffman-La Roche6 where the ECJ (European Court of Justice) defined the concept of dominance as: A position of economic strength enjoyed by an undertaking which enables it to prevent effective competition being maintained on the relevant market by affording it the power to behave to an appreciable extent independently of its competitors, customers and ultimately of its consumers.7 It is commendable that the ECJ indicates the need to protect the interests of the consumer; however is this determination on the basis of the economic grounds of

The Physiology of the Nervous System Research Paper

The Physiology of the Nervous System - Research Paper Example The central nervous system is divided into two sections: the central nervous system and the peripheral nervous system. The central nervous system is composed of the Brain and the spinal cord. This system controls behavior of a person. All body sensations are transmitted to the central nervous system in order to be interpreted and acted upon (Chiras 34). All nerve impulses that stimulate muscles to contract and the glands to secret substances get all their instructions or messages from the central nervous system. The peripheral nervous system on the other hand is composed of a network of nerves. This is the systems pathway to the brain for all the five senses and helps human beings I adjusting to the world around them (Givens and Reiss 55). The brain is the central organ of the nervous system in all vertebrates. It is a complex organ whose functioning is essential to the survival of any animal. It consists of four main parts: the cerebrum, the cerebellum, the brain stem and the diencephalon or the forebrain stem. The brain is composed of two matters, the gray matter which the active part of the brain that receives and stores impulses and the white matter that carries impulses from and to the gray matter. The cerebrum is divided into two hemispheres each with four lobes namely frontal lobe, temporal lobe, parietal lobe and occipital lobe (Glees 42). These are responsible for various functions such as hearing vision, speech, judgment etc. The cerebellum is responsible for maintaining equilibrium, receipt of relayed tactile, auditory and visual input and fine motor coordination. The mid brain provides conduction pathways and provides a center for righting, postural and audio visual reflexes. The brain stem also called Medu lla oblongata is the center for regulation of vital centers that include respiration, heartbeat and basomotor activators. The diencephalon consists of the thalamus responsible for arousal and conscious recognition of crude sensations such as temperature and pain and the hypothalamus responsible for many functions such as monitoring chemical composition of blood, control of hormone secretion, control of sleep and appetite (Glees 45). The spinal cord is a cylindrical structure that extends from the foramen magnum through the spinal foramina of the vertebral column to the upper portion of the lumber region. It houses both the motor and the sensory nerves. Basically the spinal cord is an extension of the brain that runs down the back protected by the vertebral column. It is surrounded by a fluid called the cerebrospinal fluid to protect the nerve tissues against injury.it is also protected by the meninges, a layer of three membranes, that guard it and the brain from bacteria. It is comp osed of millions of nerve fibers that transmit information to all body parts (Swan 55). The peripheral nervous system is composed of the nerves that connect the central nervous system to other remote parts of the body. It is divided into the cerebrospinal nervous system: which consists of cranial nerves that perform different functions ranging from sensing to controlling movements. The autonomic nervous system which regulates actions of secretory activity of glands and the involuntary contraction of smooth muscles in blood vessels, skin heart etc. it operates without conscious control. It is composed of the sympathetic system and the parasympathetic system. The spinal nerves carry impulses between the spinal cord, skin muscles and other structures. They are 31 in total (Givens and

The Methods of Data Collection and Analysis Term Paper

The Methods of Data Collection and Analysis - Term Paper Example A researcher’s expertise, knowledge, and thoughts influence the research to a large extent.   There are several situations in which qualitative research is more suitable such as to gain better understanding of lesser know phenomenon, or gather more information or new viewpoints. Since there are no standardized methods of qualitative inquiry practitioners usually follow a generally accepted sequence of steps. The first step towards designing qualitative research is to ascertain the focus of the study and the objectives which should also be able to justify the need for a qualitative research paradigm. This is followed by the identification and location of the sample group and size. Data collection, recording, interpretation strategies and timeline also need to be planned ahead. Sampling in qualitative research is mostly done through purposive method so that a specific population is targeted to receive in-depth information and build a case study. Purposive sampling is also of many types such as snowball, convenience and needs to be decided according to the objectives of the research. Data collection techniques in qualitative research usually employ interview focus group discussions and observation methods as well as the secondary review of available data. Inter views are open ended and can be in the form of informal conversations, semi-structured or standardized interviews. On the other hand, observations provide rich data about respondents in their natural settings. It allows the researcher to interpret a lot of information about the subjects without them even being aware of. Observations also allow the opportunity to record verbal and non-verbal cues in given settings, situations and among other people. At times, a researcher may also become a participant and get involved in the groups activities to gain insider knowledge about he subjects, especially when studying cultures. In addition to conducting first hand interviews and observations, review of documents, reports, notes or published data effectively supplements data collection efforts. Literature review also forms one of the first steps to gain more understanding of the area that needs to be researched.

The role of scientific paradigms in the assessment of thought Essay Example for Free

The role of scientific paradigms in the assessment of thought Essay Thomas Kuhn, in his work entitled The Structure of Scientific Revolutions, discusses the very nature and necessity of what he calls scientific revolutions. In this particular work, Kuhn sees an apparent parallelism between political revolutions on the one hand, and scientific revolutions on the other. Kuhn writes, â€Å"Scientific revolutions†¦ those non-cumulative developmental episodes in which an older paradigm is replaced in whole or in part by an incompatible new one† (2000, p.503). On a preliminary note, paradigms are frameworks in and through which we approach phenomena, in general. They are models, so to speak. The idea is rather simple. Let us consider the choice of models in epistemological theory. The traditional epistemological schools of thought [rationalism and empiricism] have different models. The model adopted by the rationalists was pure mathematics, whereas the empiricists adopted experimental or empirical science. As one may have already noticed at this point, it is not difficult to see why rationalism and empiricism stand as rival epistemological theories. The choice of model is significant to their fundamental disagreements. Naturally enough, different models employ different methodologies, different methodologies in turn, generate different types of knowledge, which, consequently, have different criteria of proof or validity. Scientific development, as Kuhn contends, may appropriately be characterized by paradigm shifts and this he calls scientific revolutions. It is important to note that scientific developments do not occur in a vacuum. For the aforementioned reason, there is a felt need to situate scientific developments in the historical context within which they are conceived, proposed and ultimately, institutionalized and integrated as part of society’s shared knowledge. This is to say that scientific revolutions are also proper objects of historical analysis and discourse in as much as political revolutions are. Kuhn contends that there is a parallelism between political and scientific revolutions. As pointed out earlier, it is important to note that he characterizes scientific revolutions as â€Å"those non-cumulative developmental episodes in which an older paradigm is replaced in whole or in part by an incompatible new one. † Kuhn’s characterization emphasizes two important points. First, â€Å"that there is a replacement of an old paradigm by a new one†. Second, â€Å"that the new paradigm is not merely something new; it is also incompatible with the old paradigm†. This is to say that the incompatibility or the irreconcilability of the new paradigm with the old paradigm serves as warrant for the necessity of such a revolution. Although there are significant differences in both scientific and political developments, Kuhn argues that one may be justified in using the notion of revolution as a metaphor for understanding them. He writes, â€Å"Political revolutions are inaugurated by a growing sense often restricted to a segment of the political community, that existing institutions have ceased adequately to meet the problems posed by the environment that they have in part created. In much the same way, scientific revolutions are inaugurated by a growing sense, again often restricted to a narrow subdivision of the scientific community that an existing paradigm has ceased to function adequately in the exploration of an aspect of nature to which that paradigm itself had previously led the way† (2000, p.503). Kuhn’s parallelism is thus, founded on the idea that in both cases, a sense of malfunction [in our institutions as for the case of the political, and in our paradigms as for the case of the scientific] necessitates for the occurrence of a revolution.

Properties of Enzyme Catalysts

Properties of Enzyme Catalysts Introduction Enzymes:Enzymes are single or multiple -chain proteins that act as a biological catalysts with the ability to promote specific chemical rxn under the mild condition that prevail in most living organism. Over-view of Enzymes catalysts All reaction in the body are mediated by enzymes, which are protein catalysis that increase the rate of reaction without being changed in overall process. Among the many biologic reaction that are energetic possible, Enzyme selectively channel reactant called substrate into useful pathways. Enzynes thus direct all metabolic events. Enzyme are Protein Catalyst that increase the velocity of the chemical rxn, and are not consumed during the rxn they catalyse. Some type of RNA act like a Enzyme, RNA with catalytic activity are called Ribozymes. Enzymes are protein catalysts, they influence the kinetics but not the thermodynamics of a reaction Increase the rate of a chemical reaction Do not alter the equilibrium Properties of enzymes Enzyme molecules contain a special pocket called a active site. The active site contain amino acid side chain that create a three dimention surface complementary to the substrate . the active site bind the substrate , forming an enzyme substrate (ES) complex. The ES is converted to enzyme product(EP), which subsequently dissociated to enzyme and product. Catalytic efficiency: Most enzyme catalytic rxn are highly efficient , proceeding from 103 to 108 times faster than the uncatalysed rxn. Eacg enzyme molecule is capable of transforming 100 to 1000 substrate molecules into product each sec. The number of molecules of substrate converted to product is called the turnover no. Characterstic of Enzymes Certain substance is small amount have unique capacity of speedingup chemical rxn without being alter after the rxn, they acceleration the velocity of the rxn without necessary initially it. Substance that behave in this manner are called catalyst or catalytic agent. For eg hydrogen and oxygen do not combine to any appreciable extent under normal atmospheric condition. However unlike platinum , while is inorganic , enzyme are organic compound produce by living organism. Thus we may define enzyme as organic catalyst produced by a organic cell. The three distinctive characterstic are 1)specificity. 2)high Catalyst rate 3)high capacity for regulation. A general model of reaction kinetics of biological systems Dyanamic mathematical model in biotechnology require beside the information require the stoiciometry ok the biological rxn system.. The identification of a priori unknown reaction kinetics is often a critical task due to the non-linearity and (over-) parameterization of the model equations introduced to account for all the possible modulation phenomena. The contribution of this paper is to propose a general formulation of reaction kinetics, as an extension of the Michaelis-Menten kinetics, which allows limitation/activation and inhibition effects to be described with a reduced number of parameters. The dianamic model of a perfectly stirred tank bioreactor is usually derived from a mass balance which lead to a differential eq systwm for the concentration vector ) = c0; r(c(t))=q(c(t))cx0(t) The matrix âÅ'ˆâ‚ ¬R^m*n contains the information on the stoichiometry of the reaction system and is usually timeinvariant. The biological reactions r â‚ ¬ R ^ m are catalysed by the viable biomass, whose concentration is denoted by cx0(t); and the specific reaction rate vector q â‚ ¬R^m is usually a non-linear function of the concentrations. Dâ‚ ¬ R is the renewal (or dilution) rate and u â‚ ¬ R^ n containsthe reactor input/output conditions. There are a large variety of mathematical descriptions of the reaction kinetics available in the literature. A systematic approach is, therefore, necessary to find the best model structure and the best values ofthe model parameters with respect to some imposed criterion. For instance, in terms of model identification, the optimal structure is characterised by minimal correlations between parameters and maximal identifiability properties. In terms of state estimation and control, however, simplicity and (non-)linearity play impo rtant roles.[5] ENZYME CATALYST Most of the rxn that occur in living organism are catalyst by molecule called enzyme. Most enzymes are proteins (certain RNA molecules also act as enzyme). An enzyme is in specific in its action. Many enzymes catalyst only the conversion of a particular reactant to a particular product ;other enzyme catalyst only a certain class of rxn(by ester hydrolysis) . Enzyme speed up rxn rate very substantionally and in their absent most biological rxn occur . The molecule an enzyme act on is called the substrate.the substrate bind to a specific active site on the enzymeso form as enzyme substrate complex. Some physiological poison act by binding to active site of an enzyme,there blocking the action of the enzyme.the structure of an inhibitor may resemble the structure of enzyme substrate .Cyanide act by blocking the enzyme cytochrome oxidase. The single called Escherichia coli, a bacterium that flourished in human colons, contain about 2500 different enzymes .[6] Enzyme Kinetics 1 Michaelis-Menten Kinetics 2.Lineweaver-Burk Kinetics 3. Hanes-Woolf Kinetics 4. Eadie-hofstee 5. Reversible Inhibition[7] K1 k2 E+S ↔ ES ↔ E+P k-1 k-2 E is the free enzyme , S is the substrate, ES is the enzyme substrate complex p is the product. Thp overall rxn is s gives p. The enzyme is assumed in step 1 and rearranged in step 2.Enzymes can catalyze up to several million reactions per second 2.Enzyme rates depend on solution conditions and substrate concentration. Conditions that denature the protein abolish enzyme activity, such as high temperatures, extremes of pH or high salt concentrations, while raising substrate concentration tends to increase activity. To find the maximum speed of an enzymatic reaction, the substrate concentration is increased until a constant rate of product formation is seen. This is shown in the saturation curve on the right. Saturation happens because, as substrate concentration increases, more and more of the free enzyme is converted into the substrate-bound ES form. At the maximum velocity (Vmax) of the enzyme, all the enzyme active sites are bound to substrate, and the amount of ES complex is the same as the total amount of enzyme. However, Vmax is only one kinetic constant of enzymes. The amount of substrate needed to achieve a given rate of reaction is also important. This is given by the Michaelis-Menten constant (Km), which is the substrate concentration required for an enzyme to reach one-half its maximum velocity. Each enzyme has a characteristic Km for a given substrate, and this can show how tight the binding of the substrate is to the enzyme In most experimental studies on enzymes kinetics, the enzyme concentrationis much less than the substrate concentration; [E] [ES]-[E][P] 0=([E] -[E][S])(k[E][S]-[P])-(+)[ES] If [is the initial enzyme concentration than [E]=[E]+[ES].since the conc is [E]during the rxn is generally not known while [E] is known , we replace [E] by [E] The const rate is =- R=[E][S]-[ES] R=[E][S]-([S]+[ES] Since the concentration of the intermediate ES is very small, we have Usually,the rxn is followed only to a few percent completion and the initial rate determined. Setting the product concentration [P]equal to 0 and [S]equal to [S] We get as the initial rate r where the Michaelis Menten const is defined by . The reciprocal of above eq is 1/r= 1/ Equation 2 is the Michaelis Menten eq , and above eq is the Lineweaver Burk eq. One measure r for several [S] values with [E] held fixed. The constant Since [E] is known . strictly speaking r is not the rate at t=0 , since there is a short induction period before steady state condition are establish . Although many exp studies on enzyme kinetic give a rate law in agreement with the Michaelis Menten eq .the mech ‘a is grossly over simplified. For one thing , there is much evidence that , while the substrate is bound to the enzyme , it generally undergoes a chemical change before being released as product . hence a better model is E + S ES ↔ EP ↔ E+ P The above model gives a rate law that has the same form as the Michaelis Menten eq but the const are replaced const with diff significance . Enzyme rxn are quite fast but can be studied using â€Å"classical† methods by keeping [E] and [S]very slow. Lineweaver- Burk Equation The method describe for the determination of is someone complex and therefore simpler method have been devised. Two such method are given below: First method-a convient means of evaluating and is to plot kinetic data as the reciprocals of v and (S) where v velocity and (S) is the total conc of substrate. such a double reciprocal was proposed by Hans Lineweaver and Dean Burk in 1934. If one take the reciprocal of Michaelis Menten eq, the following eq is formed This is known as Lineweaver- Burk Equation. This eq is the form y=mx+b, if one condition the variable to b and 1/(s). When one plots a graph against these two variable , a straight line is obtained . the slop of this line corresponds to and the 1/v intercept corresponds to 1/. Since can be determine from the intercept , the can be calculated . Second method: another graphical method for the measurement of for experimentel data on V as a measure of (S) makes use of the above Lineweaver- Burk Equation . multiplication on sides of the by (S) gives: A plot of verses (S) gives a straight line on axis is and the slope is and can be obtained from intercepy of the slope. A lineweaver burk plots provide a quick test for adhereance to Michaelis Menten eq kinetic and allows easily evaluation of the critical const . it also allow the discrimination between diff kinds of enzyme inhibition and regulation. A disadventure of lineweaver-Burk plot is that a long extrapolation is often require to determine , which corresponds uncertainty in the result. Consequently , other way of plotting the data are sometimes used. Alternate plot are based on Hanes-eq: [s]/v So that v/[s] is plotted against v. The relative merit of the Lineweaver-Burk, Hanes and Edlie-Hoffstee eq for the determination of and are llustrated below in fig. Using the same set of e ixperimental values of v for a series of substrate concentration . it can be seen that the lineweaver-Burk eq gives the unequal distribution of points and greater emphasis to the points at low substrate concentration that are subject to a greater experimental error, whilst the Edlie-Hoffstee eq and a Hans eq gives a better distribution of points. In the case of the Hans plot , greater emphasis is placed on the experimental data at higher substrate 1)Lineweaver plot 2)Hanes plot 3) Eadie-hofstee plot Lineweaver burk, Hanes and Eadie hofstee plot the same set of experimental data of the effect of substrate conc. [S] on the initial rate v of the enzyme catalyst rxn. Reversible Inhibition Now consider the effect of reversibly-binding inhibitors on an enzyme. If an inhibitor binds reversibly at the same site as the substrate, the inhibition is referred to as competitive. If the inhibitor binds to another site on the enzyme, the binding is described as noncompetitive. These two alternative behaviors may be distinguished by their effects on Lineweaver-Burk or Hanes-Woolf plots. If a reversible inhibitor can bind to the enzyme active site in place of the substrate, it is described as a competitive inhibitor. In pure competitive inhibition, the inhibitor is assumed to bind to the free enzyme but not to the enzyme-substrate (ES) complex. The binding is described as shown below: Here Ki is the dissociation constant for the EI complex. EI does not react to form E + P, and the enzyme is unable to bind both S and I at the same time. There are several graphical methods for detecting and analyzing competitive inhibition. The Michaelis-Menten, Lineweaver-Burk, and Hanes-Woolf equations can all be modified to include a term that describes the inhibition by I. Choose one of the cases below to consider each of these in more detail: The Michaelis-Menten equation for competitive inhibition is: The Lineweaver-Burk equation for competitive inhibition is: The Hanes-Woolf equation for competitive inhibition is: Noncompetitive Inhibition If a reversible inhibitor can bind to the enzyme at a site that is distinct from the active site, it is described as a noncompetitive inhibitor. In pure noncompetitive inhibition, the inhibitor binds with equal affinity to the free enzyme and to the enzyme-substrate (ES) complex. The binding is described as shown below: Here Ki is the dissociation constant for either the EI complex or the IES complex. Neither of these complexes can react to form E + P. There are several graphical methods for detecting and analyzing noncompetitive inhibition. The Michaelis-Menten, Lineweaver-Burk, and Hanes-Woolf equations can all be modified to include a term that describes the inhibition by I. Choose one of the cases below to consider each of these in more detail: The Michaelis-Menten equation for noncompetitive inhibition is: The Lineweaver-Burk equation for noncompetitive inhibition is: The Hanes-Woolf equation for noncompetitive inhibition is: Limiting Kinetics of Enzyme-Catalysed Reactions At very low concentrations of substrate many enzyme-catalysed reactions display approximately second-order kinetics, with rate given by the following equation: v = kA [E]0 [A] . . . . . . . in which the symbol kA (or, in general, kR for a reactant R) is the apparent second-order rate constant or specificity constant and [E]0, which may also be written as [E]t or [E]stoich, is the total or stoichiometric concentration of catalytic centres. The rationale for the subscript 0 is that the total enzyme concentration is normally the concentration at the instant of mixing, i.e. at time zero. Conversely, at very high substrate concentrations the same reactions commonly display approximately first-order kinetics (zero-order with respect to substrate): v = k0 [E]0 . in which k0, which may also be written as kcat is the apparent first-order rate constant. Although these limiting types of behaviour are not universally observed, they are more common than Michaelis-Menten kinetics)and provide a basis for classifying inhibitory and other effects independently of the need for Michaelis-Menten kinetics. The quantity k0[E]0 is given the symbol V and the name limiting rate. It is particularly useful when k0 cannot be calculated because the total catalytic-centre concentration is unknown, as in studies of enzymes of unknown purity, sub-unit structure and molecular mass. The symbol Vmax and the names maximum rate and maximum velocity are also in widespread use although under normal circumstances there is no finite substrate concentration at which v = V and hence no maximum in the mathematical sense. The form Vmax is convenient in speech as it avoids the need for a cumbersome distinction between capital V and lower case v. When a true maximum does occur the symbol vmax (not Vmax) and the name maximum rate may be used for the true maximum value of v but care should be taken to avoid confusion with the limiting rate. Enzyme Mechanism: Enzyme kinetic studies,together with the other typeof investigation have led to inside into the way in which enzyme exert their catalytic action.aspects of this are of special interest . This specificityof enzymes is explained in terms of the an elaborating of Fischers â€Å"lock and key†which is concerned with the way in which an enzyme and the substrate fixed together in forming a Enzyme substrate complex and in undergo subsequent rxn . the second aspect is the very high effectiveness of enzyme in comparison with other catalyst. the high effectiveness of catalyst almost always is associate with a low energy of activation for the rxn. in some cases the effect has been attributed to the fact that the enzyme is acting as a bifunctional catalyst, in tha two catalytic group are presentside by side at the active centre. Transition state : When a chemical reaction occurs, the energy content of the reacting molecule or atom increases. This is why most chemical reactions, whether they release heat or absorb heat, happen faster as the temperature is raised. The high-energy state of the reactants is called the transition state. For example, in a bond-breaking reaction, the transition state may be one where the reacting bond, although not completely broken, is vibrating at a frequency high enough that it is equally likely to split apart as to reform. Forming reactants or products results in the loss of energy from the transition state. This principle is shown in Figure 1 , where the increased energy of the transition state is represented as a hill or barrier on the energy diagram. Catalysts reduce the height of the barrier for achieving the transition state. General Catalytic Mechanism Catalysed reaction occur by a wide variety of mechanism.There is however one pattern that applies to a no of single substrate rxns catalysted by surfaces,enzymes, acids and bases. It is useful to consider this schmene of rxn first show as to appreciate the similarities that exist between certain rxn that are catalysted by different type od catalyst. The rxn schme: C + S ↔ X + Y X + W ↔ P + Z Here C represent the catalyst and s is the substrate; X and Y are intermediate , the first of which undergoes a second rxn with a species W to give final product or products P together with the addition substance Z. This scheme shows only the kinetically significance reactions; the substate Y and Z undergo other process that do not have any effect on yhe kinetic behaviour. To simplify the treatment it is assumed that the second rxn does not in the reverse direction ; this can b ensured if the product P is removed as far as it is formed. In surface catalysis X is an adsoption complex, Y and W are non exitance. The const in this case are first order rate const, while is the second order const. In catalysis by acid and base however Y and W play important role. Thus i c is an acid catalyst, rxn 1 involces the transfer of a proton to S,so that Y is the base conjugate to the acid C. In acid catalyst the intermediate X is the protonated substrete SH+ and a rxn 2 is proton is transferred to a species W. The species W therefore has basic properties and it may b molecule of a solvent and a solute. For eg It may be the species Y formed in 1 step . we will see that the kinetic behaviour depends in an important way on wheather the intermediate X transfers its proton to solvent molecule or to a solute molecule. Conversely in base catalyst Y is the acid conjugate to the base C.the intermediate X is the substrate Molecule minus a proton., and in rxn 2 it accepts a proton from W.again we have a solvent molecule or a solute molecule.in some situations a rate with which a intermediate X undergoes rxn 2 may be sufficiently slow that the first rxn may b regarded as being at equilibrium.the exact condition for this is [W][X][Y].since this case corresponds to Arrhenius concept of an intermediate in eq with the reactants, such intermediate have being called Arrhenius intermediates. The converse case is that the condition is [X][Y]the concentration of X is small and the steady state treatment may be appliedto it. Intermediate of this kind have been called Vant Hoff intermediates. If neither of this of this extreme condition applies , the kinetic situation is more complicated , and the appropriate differential eq have to be solved. Only the equolibium and steady-state treatments are considered here. Equilibrium Treatment : Arrhenius intermediates In this case the equation : Applies. However , the concentration of C and S do not correspond necessary to yhe initial concentration [C] and [S]. Since appreciable amount of C and S have been used to form a intermediate X. These initial concentration may be expressed as [C]=[C] + [S] [S]= [S] + [X] As long as attention is confined to initial rates. Eq a become This is quadratic in [X] and can be solve for [X]. Yhen the expression for rate equal to k[X][W] , can be written down. However it os, more useful to consider two special cases. Case 1: if the initial conc of the substrate is much greayer than that of yhe catalyst, that is, if [S][C], it follows that [S] [X] is very close to [S], since [X] cannot exceed [C]. Eq b there fore reduces to : And thus The rate of rxn therefore V=[X][W]= This rate eq correspond toa variation of rate of all type represent .At lower substrate conc , when K[S][Y], the rate become independent of [S], as long as the condition [S]>>[C] holds, however the rate varies linear with [C]. This type of behaviour is characteristic or single-substrate rxn on surfaces and of enzyme rxn. For both of these the species Y and W are nonexistence and eq c become: The eq is also eq to the Michaelis Menten eq for enzyme rxn. This eq usually written Where is the Michaelis const , is equal to 1/k in the present treatment. In rrn catalysed by acid and base it will be seen that the rate remain linear with the substrate concentration ; this is because of the special type of equilibrium that are rapidly established in the sol. Case 2: on the other hand , if the catalyst is greatly in excess of the substrate, that is [C]>>[S] eq a reduces to And the rate of rxn is The rate now varies linearily with the concentration of substrate , but the variation with the catalyst concentration . (b)The rate of reaction as a function of substrate conc for the case in which [S]>>[C] (a) rate of rxn as a function of catalyst concentration for the case[C]>>[S] Steady-state Treatment:Van,t hoff intermediate If the condition [W]>> applies, the concentration of X is small and the steady state treatment is available. The steady-state is substitution of [C] -[X] for [C] and of [S]-[X] for [S} gives since [X] is very small the term in can be neglected ; with its approximation above eq gives the rate is therefore this eq again indicates that at low conc of either catalyst or substrate the rate is proportional to either [C] or [S] ; at a higher concentration of either the rate become independent of that concentration . in catalyst by surface and enzymes , W and Y are nonexistence and the rate eq become An eq of essentially this form was first derived by Briggs and Haldane for enzyme reaction Catalyst By Enzyme Catalysis by enzyme , the biological catalyst , is much more specific than that by acids and bases. soe enzyme shows absolute specificity ; an eg is urease, which only the catalyzed of Urea. A lower degree of specificity is shown by such enzyme as the proteolytic enzymes, which catalyst the hydrolysis of the peptide linkage provided that certain structural condition are specified in the neighbourhood of the linkage.; this is known as group specificity. many enzyme exhibit stereochemical specificity, in that the catalyze the rxn of one stereochemical form and not the other.the proteolytic enzyme.The enzymes are protein but may be associated with non protein substance that essential to the action of enzyme.the action of enzyme shows some resemblance to the catalytic action of acids and bases but is more complicated. the present treatment of enzyme kinetics is confined to the influence concentration, ph, and temperature and to some brief comments about enzymes mechanisms. Measurement of the kinetics of biological systems at elevated temperatures utilizing flow techniques Continuous flow-type reactors have been used to study the kinetics of biological systems for quite some time. For continuous media sterilization, tubular flow reactors are particularly useful being simple in character and easy to control. However, one aspect quite often neglected in sterilization calculations is the residence time distribution of the reactor system. Serious errors in estimating the degree of bacterial destruction can be encountered if the residence time distribution is neglected; especially when a high degree of destruction is desired. This paper reports a study made to characterize and use the residence time distribution of a tubular reactor in the interpretation of high-temperature, short exposure time data for inactivation of Bacillus stearothermophilus spores. Mathematical models accounting for the residence time distribution of the tubular reactor have been proposed and employed to obtain high-temperature death-rate data.[14] Result Since enzymatic reactions are so important to biological chemical reactions, it is of great interest to be able to model them. By use of the study of chemical kinetics, it is possible derive rate equations for the steps involved in an enzymatic reaction. These rate equations are differential equations and can be used to model theconcentrations of each compound in the system. However, this system of differential equations is hard to determine experimentally because of the difficulty of determining the rate equations into theMichaelis-Menten enzyme equation. Many benefits stem from this transition. One benefit is the fact that it is now easy to determine the constants related to the enzyme equations. However, how do we know the Quasi-Steady-State Assumption is valid? It seems reasonable from a physical argument. Byuse of dimensional analysis, we can give a more rigorous mathematical argument for the Quasi-Steady-State Assumption. The Michaelis-Menten enzyme equation is very important i n the study of cellular systems by allowing a model that can be easily derived through experimentation.
