Freedom Essay

Freedom- what so many people wish for. It was summer of the year 2010, a time when I could finally enjoy myself and be comfortable for who I am. Summer was a time that everyone loved but going back to the year 2008 for me it was a time of darkness. All the girls on the beach showing off their new bikinis and all the boys being shirtless and showing off their looks and then there is me†¦. A girl named Page Duncan aged 15 who have no friends because she weighs 70 kg.In November 2007 it was starting to get hot so all my friends and I decided to go to the beach. As we arrived the temperature was getting hot so everyone decided to put on their bikinis for a swim but I didn’t feel comfortable because of my body so I chose to wear a one piece. As I got back from the change rooms some of my friends made comments saying â€Å"oh my god you’re so fat† and â€Å" I didn’t know whales could stay on the sand that long† and as they were saying it they all la ughed. When the girls said that to me it made me cry and be really upset so I decided to ring my mum to pick me up. Whilst on the phone with mum she asked me why I wanted to leave so early so I lied to her saying â€Å"I feel sick† so she wouldn’t know.After this day I no longer had friends, I was no longer comfortable with my self, and I was always upset about my body weight. The next day I went to school, as I arrived the whole school laughed at me and again calling me fat. Clearly this was because of yesterday. As the day went I got bullied time after time again. Finally the day ended where I found my self in my room free from all bullying until I went on Facebook. I opened up my message box and received messages saying, â€Å"You’re so fat†, â€Å"go kill your self†, â€Å"you’re ugly†. When I had read this I found my self in so much pain and anger.Today I don’t want to go to school so I am going to ask mum if I can stay ho me because I am feeling sick. Mum thank God approved so I locked my self in then  room and started crying. After a while I had soaked in so much anger and decided to cut my self. This felt good and I realised it released my anger so I did it again and again and again. Eventually I stopped because I found myself bleeding that much that I had blood on my blankets that was red as cherry.The next day mum calls me for breakfast but I am not hungry so I replied with â€Å"mum I’m not hungry†. Mum then walks into the room and see the scars on my arm and sees the blood on the blankets and asks me â€Å"honey what’s wrong with your arm?† so I reply with â€Å"mum it’s okay I just scratched me arm† so she replied with a â€Å"oh okay be careful next time and go put a band aid on and also come get breakfast†. I chose to stay in my room so I can starve my self so I can have a perfect body.As the days went on I find myself cutting my self more a nd more and also not eating and I love it. I finally am getting happy with my body, as I have lost 20 kg, which means I am now 50 kg.One day in October 2009 mum confronts me because she again notices my scars and notices I have lost weight so she wants to take me to the doctors so we did to find out that there was nothing wrong with me. Mum tells me she is still not satisfied so she decides to take me another doctor but again nothing is wrong.When I got home I decided to cut my self again, whilst doing it I cut a vein all of sudden BOOM I have past out†¦A few minutes later mum walks into my bedroom and finds me passed out with blood everywhere. Mum starts panicking and rings triple zero, she then applies pressure till the ambulance come to slow down the loss of blood. The ambulance finally arrives and takes me to hospital.Page Duncan wakes up†¦ â€Å"Hello there, I’m your nurse, you nearly died with the amount of blood you  lost. You have been unconscious for 2 days. I m also here to tell you that you have been diagnosed with depression† mum then walks into the room and is upset she asks me â€Å"why are you doing this†, mum the reason I am doing this is because I am fat and I have no friends. ‘Mum cries’ Mum please don’t be upset and she replies with â€Å" look I am upset about this but that’s okay know because I am going to fix this†.When I finally get out of hospital mum decides to have a talk. She says, † Look Page back in my day I actually was diagnosed as well but I got through it and so can you. I know this is going to be tough but we are going to get through it. I have arranged an interview with the teacher so that they are aware and can help you, I have got you medicine and also if you are that concerned about your weight you can go on a weight program if you’re interest† okay thanks mum I really appreciate it, I really didn’t know you experienced this. I’m sorry.2010 summer came and I am healthy, I am happy, 2 years later at 60kg, confident and now have friends that appreciate for who I am, I can now put a bikini and not be conscious and most in importantly I owe it all to my mum for getting me through this. After all this time I decided to go to the beach and not be scared about what others think and accept that if people want to bully me they are not true friends.In conclusion you do not have to be skinny or good looking to have fun or put on a bikini or be shirtless, it’s all about appreciating what you have. You don’t need these things to have freedom. Page Duncan was diagnosed with depression because of what other people thought. She then overcame this with the help of others and now realises that you don’t have to be skinny or good looking or smart to be free and happy. Her w eight does not longer get the better of her because she knew if they said hurtful things that they weren’t true friends. The best way to describe is â€Å"if you believe you will achieve†.

The Debate surrounding the Legalization Marijuana and your position on Research Paper

The Debate surrounding the Legalization Marijuana and your position on the issue - Research Paper Example The drug was essentially sold as tincture which was a medicinal tea and was quickly adapted by the English cultures. The Indian government regulated the circulation of the drug where it required the importing nations to use it for medicinal and scientific purposes only. Today, marijuana can be consumed through different forms which include smoking, as a vaporizer, cannabis tea or as edibles. Cannabis can be termed as hemp; if it is an annual herb used for non drug purposes (Jonathan, Hawken, Kilmer and Kleiman 4). The product is used for industrial purposes which are licensed by the government. The industrial hemp produces fiber which is used as fuel as a by-product. The hemp seeds can further be consumed as food by human beings. The use of marijuana has the benefit of improving the economy of the States. The benefit can be realized through taxation which generates income to the legalized States and the nation as a whole. The income realized can be used to fund government projects and promote educational campaigns across institutions (Burnham 23). According to Burnham Para 44 marijuana legalization promotes the creation of jobs. The marijuana industry is exponentially growing which can directly and indirectly promote the creation of jobs. The industry employs numerous people, who are engaged in the cultivation, manufacturing, distribution, consumption and advertising of the drug. Decriminalization of marijuana necessitates the reduction of crime. The sale and distribution of the drug can be regulated so as to prohibit illegal trading which can be upheld by educational campaigns so as to reduce marijuana related offenses (Burnham 76). The offenders can further be educated on the effective measures to curb frustrations and their illegal motives. Burnham 102 confirms marijuana contains active components of cannabinoids which have medical benefits in the human life. The cannabinoids have potential elements which modulate pain, increase

English class - Essay Example Thus, the article finds that a general apprehension exists that video games cause violent behavior in children. However, the article challenges this contention as it does not seem tenable, though it concedes to the notion that to a certain extent, video games may impact children’s behavior. The article focuses on the premise that video games contain a lot of violence, bloodshed, objectification of females and sexual content. However, it emphasizes a more significant concern that viewing experience in the media, in terms of audio visual components, are â€Å"extraordinarily life like, and these effects can be particularly striking in violent games† (Video Games and Violence 1). It also concedes to the fact that despite the existence of rating systems by the ESRB, children disregard the classification and even those below 13 years watch the content that is permissible to those in the age group of 17. The article also refers to research studies that â€Å"lend credence to concerns about the impact of violent video games† (Video Games and Violence 3). However, this does not prove that games such as GTA cause violent behavior in children. The article, further, challenges this concept by arguing that there is â€Å"little or no evidence to support any of these theories† which purport that violence in the video games such as GTA can provoke violent behavior in children (Video Games and Violence 2). I believe that exposure to violent media or video games alone cannot make children to indulge in violent behavior. My research premise is based on the concept that many factors such as genetic framework, social circumstances, psychological reasons etc cause violent behaviors in humans. Therefore, children who possess any such specific traits or who remain exposed to any of the causative elements, stand the chance of displaying violent behavior. I do not agree with the evidence based on a study among 1254 students, which indicates that violent games cause aggression in

Sustainability 351 wk 6 forum - Research Paper Example The company has been extremely careful to ensure that the recycled boxes are contamination free and are safe for use (Thomas, 2010). Becoming packaging neutral simply means to cut out the cycle of the useful cardboard being wasted and going directly into the landfills. The focus is to help cut out the cycle and to give a new life to the packaging material, thereby reducing the wastage and prioritizing the use of the packaging materials. Yes, the box as seen in the video clearly does meet the requirements as mentioned above (WalMart, 2014). The packaging neutral is simply a means to cut down the levels of trash, and the volumes of pollution and a means to simply expand the pace consumption of the Walmart forests. The focus and attention is to reduce the use of natural resources to the maximum possible extent. Hence, this is in the true sense in line with the definition of the ‘packaging neutral’ aspect of the

Emotions In the Workplace Essay Example | Topics and Well Written Essays - 250 words

Emotions In the Workplace - Essay Example Many employees experience negative emotions because of mental health disorders. â€Å"Symptoms of mental health disorders may be different at work than in other situations† (Harvard University, 2014). A controlling boss can also induce sadness in the employees. It is human nature to want autonomy and freedom. Controlling bosses make the employees feel like they work in a confined space like servants. Employees do not feel respected in such a place and thus become sad. Another very important cause of sadness is workplace accidents because they lower the moral of the employees (Franklin, 2014). Negative emotions disrupt the environment and culture of an organization. Negative emotions foster an unhealthy culture. An individual’s performance at work is just as good as the individual’s feelings about the work. Negative emotions not only affect the person who experiences them first but also others who work with him/her in the same office. Nobody likes working or deali ng with a depressed, sad, or mentally ill

Information Systems - Essay Example The spare capacity if available can be used for different purposes. The remote hosting at the third-party facilities as well leads the company to the curtailing of the costs while maintaining the internal control over hardware, software and communications and keeping its established relationship with the third party. Hosting at the Surebridge’s facilities, on the other hand, has the advantage of sparing the customer worry about establishing and maintaining its own IS infrastructure, investing into hardware etc. Moreover, customer receives over-the-clock access to the monitoring tools and gets a dedicated manager who is well aware of the company’s specifics and recent history. To make a sound choice, more information about both the options and the company’s particular needs is desirable in order to successfully match one with another. On the Surebridge’s side, additional required information would include price, total cost of ownership, connectivity and speed of connection, security standards with regards to transfer and processing of the commercial data, set-up time, reliability of the back-up system and assurance of operations continuity, additional services provided. On the company’s side, it would be necessary to know whether its operations and needs are quite similar to those of other companies in the industry, or does it need the customized solutions and treatment. It is also important to know if the company already has a modern IS infrastructure and some trained personnel, or an agreement on hosting with a third party in place. Moreover, the required speed and volume of processing stemming out of the scope of the company’s operations and necessity of the computers and IT infrastructure to be deployed for other purposes should also be considered. A possibility to visit Sharebridge’s facilities would be an exciting experience. I would like to start by looking at the

Business Functions and Processes Essay Example | Topics and Well Written Essays - 5000 words

Business Functions and Processes - Essay Example Primary activities are mainly associated with the creation of a particular product, whereas support activities involve assignments that support the primary activities and each other. Three of the support activities that include procurement, human resource management and technology development can be connected to primary activities, while the fourth activity (firm infrastructure) is responsible for supporting the entire value chain. The concept of value chain postulated by Porter (1985) explains that attaining competitive advantage begins with the effort to build organizational proficiency in conducting specific competitive value chain activities. The underlying aim behind performing such activity is to attempt harnessing those capabilities, which strengthen competitiveness and strategy of an organization. Given the fact that one or more of these abilities become the cornerstone of a company’s strategy and more resources are then allocated towards building greater expertise in performing these activities, the targeted abilities may ultimately become sustainable core competencies (Roper, Du and Love, 2008). In order to understand significance that Porter had attached to the value chain, it is imperative to recognize that there are two distinct and basic sources of competitive advantage. One source is a lower relative cost advantage and the other is a sort of differentiation. Although empirical research scholars have argued on the fact that many companies (specially Japanese) have been largely successful in combining the two sources mentioned above into one source, Porter continued to seek ways whereby both the sources could be developed separately (Hansen and Birkinshaw, 2007). Porter’s primary emphasis was on the argument that attaining low cost advantage or differentiation largely relies upon the disconnected activities performed by an organization. By disaggregating these activities in strategically pertinent groups, managers will be

A Raisin In The Sun English Literature Essay

A Raisin In The Sun English Literature Essay Who is Lorraine Vivian Hansberry? Lorraine was born In Chicago on May 19, 1930 She based most of her novels on her life, she was 28 years old when she wrote her first play A Raisin in the Sun which won The Drama Critics Award for best play of the year and made Hansberry the first black, youngest person, and fifth woman to win that prize. She was the youngest of four children Carl, Jr., Perry, and Mammie. Her parents were well educated successful black citizens who publicly fought discrimination against black people. Her father, Carl Augustus Hansberry, Sr., was from Gloucester, Mississippi, he moved to Chicago after attending Alcorn College, and became known as the kitchenette king after subdividing large homes that were vacated by whites who were moving to the suburbs he then sold these small apartments or kitchenettes to African American migrants from the South. Hansberrys mother, Nannie Perry, a schoolteacher and, later, ward committeewoman, was from Tennessee. At the time of Lorr aines birth, she had become an influential society matron who hosted major cultural and literary figures such as Paul Robeson, Langston Hughes, and Joe Louis. Lorraine and her siblings enjoyed privileges unknown to their schoolmates; the parents filled their children with racial pride and civic responsibility. They founded the Hansberry Foundation; an organization designed to inform African Americans of their civil rights, they also encouraged their children to challenge the segregation policies of local restaurants and stores. (Cliffnotes, James, Rosetta). When Hansberry was a child she and her family lived in a black neighborhood on Chicagos Southside. During this time segregation enforced the separation of whites and blacks which was still legal and spreaded throughout the South, Northern States. This was including Hansberrys own Hometown Illinois. Carl and Nannie Hansberry challenged defensive real estate agreements by moving into an all-white neighborhood. Hansberrys family became one of the first to move into an all white neighborhood but, a mob of whites gathered in front of the house and threw a brick through the front window, narrowly missing eight-year-old Lorraine this forced the family to move out. Her father won a narrow victory over restrictive agreements from the Supreme Court, but the decision failed to set examples on their issue. Hansberry still attended Betsy Ross Elementary and Englewood High School even though her family stayed in a all white neighborhood it didnt change her right to get a education with all the other white kids because of her skin color she still had to attend a segregated public school for blacks .Lorraine Hansberry became interested in theater in high school, and pursued this interest in college. Her familys move into a restricted white neighborhood in 1937 helped her battle with injustice; this filled her with a sense of social activism. Their struggle would become the subject of her first major play. Departing from the family tradition of attending black colleges, Hansberry enrolled at the University of Wisconsin at Madison, a predominantly white university, to study journalism, but became equally attracted to the visual arts while she was there. She also attended the University of Wisconsin and the Art Institute of Chicago and studied in Guadalajara, Mexico, from 1948 to 1950. She became more politically active after moving to New York City and writing for freedom magazine. While participating in a demonstration at New York University, she met Robert Barron Nemiroff, the son of progressive Russian Jewish immigrants, and after a short intimate relationship, she married him on June 20, 1953. After having earned his masters degree four months earlier at New York University, he had begun writing a book on Theodore Dreiser, The young couple moved to Greenwich Village and Hansberry began to write massively about the people and lifestyles that she observed around her. She was already an experienced writer and editor, having published articles, essays, and poetry in Freedom, New Challenge Magazine and other political magazines.(Shmoop, A raisin in the Sun). After leaving Freedom in 1953 to concentrate on her writing, Hansberry worked various odd jobs including tagger in the garment industry, typist, program director at Camp Unity (an interracial summer camp), recreation leader for the physically disabled, and teacher at the Marxist-oriented Jefferson School for Social Science. When her husband co-wrote Cindy Oh Cindy (1956), a ballad that became an instant hit, the profits freed Hansberry to devote her full energies to a play about a struggling, working-class black family, like the families who rented her fathers properties on Chicagos South Side A Raisin In the Sun . A Raisin In the Sun reflects the frustrations of a black family whose dreams of economic progress have been let down in 1961, it was produced as a film with most of the original cast and won a special award at the Cannes Film Festival. During this period, Hansberry was much in demand as a public speaker. She expressed her belief that art is social and that black writers m ust address all issues of humankind. As the civil rights movement climaxed, she helped to organize fund-raising activities in support of organizations such as the Student Nonviolent Coordinating Committee (SNCC), called for the abolition of the House Un-American Activities Committee, and declared that President John E. Kennedy had endangered world peace during the Cuban Missile Crisis.(Answers.com, A raisin in the Sun). During the last four years of her life, Hansberry worked hard on several plays. The Sign in Sidney Brusteins Window was produced on Broadway in 1964, but critics were less open to this play that challenged the Greenwich Village intellectuals. During its short run, Hansberry battled pancreatic cancer, diagnosed in 1963. She died on 12 January 1965, the same night that her play closed.(Grade Saver, Sherrod, Cheryl.Berkow, Jordan). Lorraine Hansberry left behind several plays some are listed below: (Answers.com, A raisin in the Sun). Nonfiction the Movement: Documentary of a Struggle for Equality, Simon Schuster, 1964.

Hansberry wrote that she always felt the tendency to record her experiences her sense of history and the confusing role of women in history are also shown in her work. She was named most promising playwright. Raisin in the Sun ran for 530 performances from 1959 to 1965; A Raisin in the Sun was a play that Lorraine based on her life while living n Chicago during segregation.(Sparknotes,A raisin in the Sun). It talked about the life of a family called the Youngers some other characters Include: Walter Lee Younger  Ã‚  The central character of the play. Walter is a dreamer. He wants to be rich and devises plans to acquire wealth with his friends, particularly Willy Harris. When the play opens, he wants to invest his fathers insurance money in a new liquor store venture. He spends the rest of the play endlessly preoccupied with discovering a quick solution to his familys various  problems. Beneatha Younger (Bennie)  Ã‚  Mamas daughter and Walters sister. Beneatha is an intellectual. Twenty years old, she attends college and is better educated than the rest of the Younger family. Some of her personal beliefs and views have distanced her from conservative Mama. She dreams of being a doctor and struggles to determine her identity as a well-educated black woman. Lena Younger (Mama)  Ã‚  Walter and Beneathas mother. The head of the family, Mama is religious, moral, and caring. She wants to use her husbands insurance money as a down payment on a house with a backyard to fulfill her dream for her family to move up in the  world. Ruth Younger  Ã‚  Walters wife and Traviss mother. Ruth takes care of the Youngers small apartment. Her marriage to Walter has problems, but she hopes to rekindle their love. She is about thirty, but her weariness makes her seem older. Constantly fighting poverty and domestic troubles, she continues to be an emotionally strong woman. Her almost unenthusiastic sarcasm helps her to survive. Travis Younger  Ã‚  Walter and Ruths sheltered young son. Travis earns some money by carrying grocery bags and likes to play outside with other neighborhood children, but he has no bedroom and sleeps on the living-room sofa. Joseph Asagai  Ã‚  A Nigerian student in love with Beneatha. Asagai, as he is often called, is very proud of his African heritage, and Beneatha hopes to learn about her African heritage from him. He eventually proposes marriage to Beneatha and hopes she will return to Nigeria with him. George Murchison  Ã‚  A wealthy, African-American man who courts Beneatha. The Youngers approve of George, but Beneatha dislikes his willingness to submit to white culture and forget his African heritage. He challenges the thoughts and feelings of other black people through his arrogance and flair for intellectual competition. Mr. Karl Lindner  Ã‚  The only white character in the play. Mr. Lindner arrives at the Youngers apartment from the Clybourne Park Improvement Association. He offers the Youngers a deal to reconsider moving into his (all-white) neighborhood. Bobo  Ã‚  One of Walters partners in the liquor store plan. Bobo appears to be as mentally slow as his name indicates. Willy Harris  Ã‚  A friend of Walter and coordinator of the liquor store plan. Willy never appears onstage, which helps keep the focus of the story on the dynamics of the Younger family. Mrs. Johnson  Ã‚  The Youngers neighbor. Mrs. Johnson takes advantage of the Youngers hospitality and warns them  about moving into an all white  neighborhood. A Raisin In the Sun portrays a few weeks in the life of the Youngers, an African-American family living on the South Side of Chicago in the 1950s. When the play opens, the Youngers are about to receive an insurance check for $10,000. This money comes from the deceased Mr. Youngers life insurance policy. Each of the adult members of the family has an idea as to what he or she would like to do with this money. The head of the family, Mama, wants to buy a house to fulfill a dream she shared with her husband. Mamas son, Walter Lee, would rather use the money to invest in a liquor store with his friends. He believes that the investment will solve the familys financial problems forever. Walters wife, Ruth, agrees with Mama, however, and hopes that she and Walter can provide more space and opportunity for their son, Travis. Finally, Beneatha, Walters sister and Mamas daughter, wants to use the money for her medical school tuition. She also wishes that her family members were not so interest ed in joining the white world. Beneatha instead tries to find her identity by looking back to the past and to Africa. As the play progresses, the Youngers clash over their competing dreams. Ruth discovers that she is pregnant but fears that if she has the child, she will put more financial pressure on her family members. When Walter says nothing to Ruths admission that she is considering abortion, Mama puts a down payment on a house for the whole family. She believes that a bigger, house will benefit them all. The Youngers future neighbors find out that they are moving to an all white neighborhood, and they send Mr. Lindner, from the Clybourne Park Improvement Association, to offer the Youngers money in return for staying away. The Youngers refuse the deal, even after Walter loses the rest of the money to his friend Willy Harris, who persuades Walter to invest in the liquor store and then runs off with his cash. In the meantime, Beneatha rejects George Murchison, who she believes to be shallow and blind to the problems of race. She receives a marriage proposal from her Nigerian boyfriend, Joseph Asagai, who wants Beneatha to get a medical degree and move to Africa with him. The Youngers eventually move out of the apartment, fulfilling the familys long-held dream. Their future seems uncertain and slightly dangerous, but they are determined to live a better life. They believe that they can succeed if they stick together as a family and resolve to defer their dreams no longer. During Act 1 Scene 1 of the play which is entitled Friday Morning it is morning at the Youngers apartment. Their small home on the South Side of Chicago has two bedrooms one for Mama and Beneatha, and one for Ruth and Walter Lee. Travis sleeps on the couch in the living room. The only window is in their small kitchen, and they share a bathroom in the hall with their neighbors. Ruth is the first one in the house to wake up so she starts to cook breakfast and this awakes Walter and Travis while Travis is getting ready Walter and Ruth talk in the kitchen they do not seem happy as they engage in some slight humor they keep mentioning a check Walter scans the front page of the newspaper and reads that another bomb was set off, and Ruth responds with anger. Travis asks them for money he is supposed to bring fifty cents to school and Ruth says that they do not have it. His constant nagging quickly irritates her. Walter, however, gives Travis an entire dollar while staring at Ruth. Travis th en leaves for school, and Walter tells Ruth that he wants to use the check to invest in a liquor store with a few of his friends. Walter and Ruth continue to argue about their unhappy lives.(Bookrags, A raisin in the Sun). Act 1 Scene 2 The Following Morning The next day, Saturday, the Youngers are cleaning their apartment and waiting for the insurance check to arrive. Walter receives a phone call from his friend Willy Harris, who is coordinating the potential liquor store investment. It appears that their plan is moving smoothly. The insurance check is all Walter needs to pursue his liquor store. He promises to bring the money to Willy when he receives it. Meanwhile, Beneatha is spraying the apartment with insecticide in an attempt to get rid of cockroaches. Beneatha and Travis start fighting, and Beneatha threatens him with the spray gun. The phone rings, and Beneatha answers. She invites the person on the phone over to the still-dirty apartment, without concerning Mama. After hanging up, Beneatha explains to Mama that the man she has spoken to on the phone is Joseph Asagai, an African intellectual whom Beneatha has met at school. She and Mama discuss Beneathas worries about her familys ignorance abo ut Africa and African people. Ruth returns from seeing a doctor, who has told her that she is two months pregnant. She reveals this information to Mama and Beneatha. Walter returns home and wants to talk about his liquor store plans. Ruth wants to discuss her pregnancy with him and becomes upset when he will not listen.(Cummings study guide, A raisin in the Sun). Act 2 Scene 1 Later that same day Later on the same Saturday, Beneatha comes out from her room dressed in the Nigerian clothes that Asagai has brought her. She dances around the apartment, claiming to be performing a tribal dance while shouting OCOMOGOSIAY and singing. Mama comes home and announces that she has put a down payment on a house with some of the insurance money. Ruth is happy to hear this news because she too dreams of moving out of their current apartment and into a more spacious home. Meanwhile, Walter is noticeably upset because he wants to put all the money into the liquor store. They all become worried when they hear that the house is in Clybourne Park, an entirely white neighborhood. Mama asks for their understanding it was the only house that they could afford. She feels she needs to buy the house to hold the family together. Ruth regains her pleasure and rejoices, but Walter feels betrayed, his dream swept under the table. Walter makes Mama feel guilty, saying tha t she has crushed his dream. He goes quickly to his bedroom, and Mama remains sitting and worrying.(enotes, Marie Rose Naiper Kowski). Act 2 Scene 2 Friday Night a few weeks later On a Friday night a few weeks later, Beneatha and George return from a date. The Youngers apartment is full of moving boxes. George wants to kiss Beneatha, but she does not want to kiss. She wants to engage George in a conversation about the life of African-Americans. It seems that George wants to marry a nice, simple, sophisticated girl. Mama comes in as Beneatha kicks him out Mrs. Johnson the Youngers neighbor visits. Mama and Ruth offer her food and drink, and she gladly accepts. She has come to visit to tell them about a black family who has been bombed out of their home in a white neighborhood. Walters boss calls, telling Ruth that Walter has not been to work in three days. Walter explains that he has been wandering all day (often way into the country) and drinking all night (at a bar with a jazz duo that he loves). He says that he feels depressed, and useless as the man of the family(Sparknotes,A raisin in the Sun). Act 2 Scene 3 Saturday moving day, one week later On Saturday, a week later, it is moving day. Ruth shows Beneatha the curtains she has bought for the new house and tells her that the first thing she is going to do in their new house is take a long bath in their very own bathroom. Ruth comments on the changed mood around the household, noting that she and Walter even went out to the movies and held hands the previous evening. Walter comes in and dances with Ruth. Beneatha teases them about acting in a stereotypical fashion but does not really mean any harm. A middle-aged white man named Karl Lindner appears at the door. He is a representative from the Clybourne Park Improvement Association, and he tells the Youngers that problems arise when different kinds of people do not sit down and talk to each other. The Youngers agree, until he reveals that he and the neighborhood coalition believe that the Youngers presence in Clybourne Park would destroy the community there. When Mama comes h ome, Walter, Ruth, and Beneatha tell her about Mr. Lindners visit. It shocks and worries her, but she supports their decision to refuse the buyout offer. Then, as she is making sure that her plant is well packed for the trip, the rest of the family surprises her with gifts of gardening tools and a huge gardening hat. Mama has never received presents other than at Christmas, and she is touched by her familys generosity. Just as the whole family begins to celebrate, Bobo, one of Walters friends, arrives. After some stumbling, he announces that Willy Harris has run off with all of the money that Walter invested in the liquor store deal. It turns out that Walter had invested not only his $3,500 but also the $3,000 intended for Beneathas education. Mama is angry and begins to beat Walter in the face. Beneatha breaks them up. Weakness overcomes Mama, and she thinks about the hard labor her husband endured in order to earn the money for them. She prays heavily for strength.(123 help me, A raisin in the Sun). Act 3 An hour later One hour later on moving day, everyone is still unhappy. Walter sits alone and thinks. Asagai comes to help them pack and finds Beneatha questioning her choice of becoming a doctor. She no longer believes that she can help people. Mama enters and announces that they are not going to move. Ruth protests. Walter returns, having called Mr. Lindner and invited him back to the apartment he intends to take his offer of money in exchange for not moving to Clybourne Park. Everyone objects to this plan, arguing that they have too much pride to accept not being able to live somewhere because of their race. Walter, very agitated, puts on an act, imitating the stereotype of a black male servant. When he finally exits, Mama declares that he has died inside. Beneatha decides that he is no longer her brother, but Mama reminds her to love him, especially when he feels hopeless.(Pink Monkey, Sauder,Dianne). The movers and Mr. Lindner arrive. Mama tells Walter to deal with Mr. Lindner, who is laying out contracts for Walter to sign. Walter starts hesitantly, but soon we see that he has changed his mind about taking Mr. Lindners money. His speech builds in power. He tells Mr. Lindner that the Youngers are proud and hardworking and intend to move into their new house. Mr. Lindner appeals to Mama, who defers to Walters statement. Ultimately, Mr. Lindner leaves with his papers unsigned. Everyone finishes packing up as the movers come to take the furniture. Mama tells Ruth that she thinks Walter has finally become a man by standing up to Mr. Lindner. Ruth agrees and is noticeably proud of her husband. Mama, who is the last to leave, looks for a moment at the empty apartment. Then she leaves, bringing her plant with her.(Cliffnotes, James Rosetta). While reading a raisin in the sun I came to a conclusion that it is essentially about dreams, as the main characters struggle to deal with the depressive circumstances that rule their lives. The title of the play refers to a line that Langston Hughes famously said in a poem he wrote about dreams that were forgotten or put off. He wonders whether those dreams shrivel up like A raisin in the Sun. Every member of the Younger family has a separate, individual dream Beneatha wants to become a doctor, for example, and Walter wants to have money so that he can afford things for his family. The Youngers struggle to attain these dreams throughout the play, and much of their happiness and depression is directly related to their achievement of, or failure to attain, these dreams. As the play progressed The Youngers eventually move out of the apartment, fulfilling the familys long-held dream. Their future seems uncertain and slightly dangerous, but they are determined to live a better life. They believe that they can succeed if they stick together as a family. By the end of the play, they learn that the dream of a house is the most important dream because it unites the family, And so did I.

Bilayer Organic Solar Cell in MATLAB

Bilayer Organic Solar Cell in MATLAB Chapter 3 Modelling and Simulation 3.1 Introduction This thesis is based on simulation of design characteristic of bilayer organic solar cell in MATLAB so it is very essential to be familiar with modelling and simulation. This chapter explains about modelling and simulation, characteristics of simulation, mathematical modelling (analytical and numerical both) and its properties, electrical modelling, work done in the field of modelling and simulation of OSC and finally small introduction of MATLAB which shows it’s features because of which this simulation work is in MATLAB. 3.2 Modelling and Simulation Modelling and simulation [1-4] is obtaining related data about how something will act without really trying it in real life. MS is using models either statically or over time, to build up data as a basis for making technical decisions. The terms modelling and simulation are often used interchangeably. Simulation skill is the tool set of engineers of each and every application domains and included in the knowledge body of engineering management. Modelling and simulation is a regulation on its own. With the addition of dynamic factor, simulation systems develop their functionality and allow to calculate predictions, estimates, optimization and what-if analyses. The meaningful abstraction of reality, follow-on in the proper necessity of a conceptualization and fundamental assumptions and constraints, is known as modelling. Simulation is execution of a model over time. Conceptualization is targeted by modelling, means modelling belongs to abstraction level and implementation is targeted by simulation, means simulation belongs to implementation level. Conceptualization (modelling) and implementation (simulation)– are the two activities that are jointly dependent, but can nevertheless be conducted by separate individuals. Modelling and simulation has helped to reduce expenses, enhance the feature of products and systems, and document. 3.2.1 Features of Simulation Interest in simulation applications are increasing gradually because of the following reasons- Use of simulation is cheaper and safer as compared to conduction of experiment. As compared to the conventional experiments, simulations can be more realistic because it permits free formation of surroundings parameters that are obtained in the active application area of the final product. As compared to real time, execution of simulation is faster because of this quality it can be used in if-then-else analysis of unlike alternatives, in particular when the essential information to initialize the simulation can simply be founded from functioning data. Tool box of conventional decision support system is being added a decision support simulation system with the use of simulation. Set up of a coherent synthetic environment is permitted by simulation which allows addition of simulated systems in the premature analysis phase through mixed virtual systems with virtual check surrounding to first prototypical elements for concluded system. If managed perfectly, the surrounding can be migrated from the growth and test domain to the domain of training and learning in resulting life cycle phases for the systems. 3.2.2 Steps for Modelling For modelling four basic steps are as follows †¢ Step 1: Monitor – In the first step conceptual model of ground profile and job objectives are developed. †¢ Step 2: Measure – In the second step theoretical model is developed which is used to explain the main processes running in the problem. †¢ Step 3: Describe – In the third step mathematical explanation of these processes are developed and to get a perfect solution verification is also done. †¢ Step 4: Verify – In the fourth step under the light of experimental physical reality, results of mathematical expression is interpretated. Confirm the suggestion, get additional measurements, enhance the complexity or precision of the mathematical result, or modify your conceptual understanding until you have complete understanding of the physical actuality. 3.3 Mathematical Modelling Fig 3.1, shows the simplest explanation of modelling – the method through which we can take out a complex physical actuality from a suitable mathematical reality on which designing of system is based. Development of suitable mathematical expression is done in numerical modelling. Mathematical modelling is a group of mathematical expressions that show the variation of a system from one state to another state (differential equations) and dependence of one variable to the other variable (state equations). The use of mathematical words to describe the performance of a system is mathematical modelling. Performance of photovoltaic system [5-7] is also illustrated by mathematical modelling. Number of different parameters (like – series and shunt resistance, ideality factor, reverse saturation current, open circuit voltage, short circuit current, fill factor, photo-generated current, efficiency) of photovoltaic system can be calculated by mathematical modelling. Fig. 3.1: Simple definition of modelling. 3.3.1 Properties of Mathematical Modelling We prefer mathematical modelling because of the following reasons With the help of mathematical model we can understand and investigate the meaning of equations and useful relations. It becomes very simple to make a educational environment in which preliminary person can be interactively occupied in guided inquiry and hands on actions with the help of mathematical modelling software (like – Stella II, Excel, online JAVA, MATLAB). Mathematical model is build up after the development of conceptual model of physical system. It is used to calculate approximately the quantitative presentation of the system. In order to spot a model’s strengths and weaknesses, quantitative outcomes obtained from mathematical modelling can be compared with observational information. The most important element of the resultant â€Å"complete model† of a system is mathematical model. Complete model is an assembly of theoretical, physical, numerical, visualization and statistical sub-models. 3.4 Types of Mathematical Modelling These can also be divided into either numerical models and analytical models. 3.4.1 Numerical Modelling – It is one of the type of mathematical modelling in which numerical time stepping method is used to obtain model response over time. Results are presented in the form of graph or table. In this thesis numerical modelling is used to analysis the design characteristic of Bilayer Organics Solar Cell. 3.4.2 Analytical Modelling – Modelling having a closed form results is called analytical modelling. In closed form results, mathematical analytic functions are used to present the response to the equations that describe variation in a system. 3.5 Electrical Modelling In this section, the electrical model for bilayer organic solar cell is described. One of the important characteristics of organic materials is their extremely small mobility, which makes modelling of their electrical properties difficult. Another problem in the electrical modelling of organic thin film devices (e. g. planar organic solar cells) was the lack of unique and precise electrical parameters for very thin layers of materials and occasionally lack of any information. Here with the aid of a self consistent loop between the Poisson equation and continuity equations for electrons and holes, the I-V curve of the device is calculated. It is assumed that the electrical current is due to the drift-diffusion transport of carrier. Consequently, in order to model the drift diffusion equations, a self consistent loop between the solutions of Poissons equation and two separate continuity equations for electrons and holes is needed. The design of the loop should be in a way such that the solution of each equation can be used as the initial conditions for the others, to generate a self correcting mechanism. The model that is used is based on the following assumptions: The generated excitons are separated right after absorption and the numbers of the generated electron-hole pairs are directly imported into the continuity equations as the generation rate . The transport properties of the organic materials can be totally modelled by mobility, DOS, bimolecular recombination term and doping levels. The connections between different layers follow the physical rules of hetero-junction connections between conventional semiconductors interfaces. The other two equations, which are solved in a closed loop with the mentioned Poisson equation, are two separate continuity equations one for the electrons and one for the holes. The flowchart of the electrical model using the mentioned equations is shown in Fig. 3.2. Fig. 3.2 : Flowchart of electrical model. 3.6 Work Done in Modelling and Simulation of OSC Pettersson et al (1999)[8] have reported a model based on the experimental short circuit light generated current action spectrum of poly(3-(4’-(1†,4†,7†-trioxaoctyl)phenyl)thiophene) (PEOPT)/C60 fullerene hetero-junction photovoltaic devices. This modelling was completely based on the assumption that generation process of photocurrent is the result of creation, diffusion and dissociation of excitons. Using complex refractive indices and layer thickness, internal optical electric field was computed. We got values for exciton diffusion length of 4.7 and 7.7 nm for PEOPT C60 respectively. Computed photocurrent and electric field distribution were used to study the effect of geometrical architecture with respect to the efficiency of device. Cheknane et al (2007)[9] has reported a photovoltaic cell in which photo-active layer of MDMO-PPV and PCBM material is sandwiched between ITO and Al electrodes, there is an additional interfacial layer of PEDOT/PSS on the top of ITO. Comparision between V-I characteristics of device with and without extra interfacial layer is done and modelled by electrical equivalent circuit. Simulation results show that V-I characteristics of bulk hetero-junction solar cell is affected by extra interfacial layer of PEDOT/PSS. Hwang et al (2007)[10] has reported drift-diffusion time dependent model of OSC based on blends of P3HT and red polyfluorene copolymer. In this model electron trapping and field dependent charge separation is used to investigate the device physics. This model is used to reproduce practical light-generated current transients observed in response to variable intensity step function excited light. Vervisch et al (2011)[11] has reported OSCs simulation using finite element method. Using finite difference time domain process, optical modelling is done and electrical characteristics is obtained by solving Poisson’s and continuity equations. Simulation results show the effect of physical parameters like exciton lifetime on OSC performance. Casalegno et al (2013)[12] has reported numerical approaches that give valuable information of microscopic processes underlying generation of photo-current in OSC. Here 3D master equation approach is used in which equations explaining particle dynamics rely on mean field guess and result is obtained numerically. Reliability of this method is tested against Kinetic Monte Carlo simulation method. V-I curve shows that the result of this method is very close to the exact result. Because of the adoption of mean field approximation for electrostatic interactions, we get biggest deviation in current densities. Strong energy disorder can also affect response quality. Simulation results show that master equation approach is faster than Kinetic Monte Carlo approach. Foster et al (2013)[13] presented a drift-diffusion model to obtain V-I curves and equivalent circuit parameters of bilayer organic solar cell. Minority carrier densities are neglected and final equations are solved with internal boundary condition on material interface and ohmic boundary condition on contacts. From the solution of this model V-I curves are calculated. 3.7 Introduction to MATLAB MATLAB [13] is a high performance language for technical computing. It integrates calculation, visualization and programming in a simple to use surroundings where troubles and solutions are presented in well-known mathematical notation. MATLAB can solve technical computing troubles faster than conventional programming language (like – Forton, C, C++). Typical uses include – Financial modeling and investigation Computational biology Math and computation algorithm development Data acquisition modeling Simulation and prototyping data study Exploration and visualization Graphics application development for scientific and engineering field Graphical user interface building Matrix laboratory is the full form of MATLAB. Basic data element in MATLAB is an array which does not need dimensioning. With the help of MATLAB number of technical computing troubles mainly those with vector and matrix formulations can be solved in a fraction of time. Basically it was written to give simple access to matrix software. For advance science, mathematics, engineering field and high productivity industrial research, progress and study MATLAB is very important instruction tool. Comprehensive collection of MATLAB functions are toolbox. Toolboxes of MATLAB permit us to study and apply specific technology. Toolboxes are available in different areas like – neural network, communication, signal processing, fuzzy logic, simulation, control system and many others. Differential equations are solved very easily in MATLAB [14-17]. We can also do modeling and simulation of solar cell using MATLAB [18,19]. 3.8 Conclusions This chapter explains about modelling and simulation. Presentation of physical configuration or activities of device by conceptual mathematical model that approximates this behavior, is called modeling. Model may either be closed form equation or arrangement of simultaneous equations that are numerically solved. Analytical and numerical both type of analysis can be used in modeling. Simulation is process of imitating the physical system behavior by considering the characteristic of an analogous but different system without resorting direct practical experimentation. For simulation we are using MATLAB which is a high performance technical computing language. We get that MATLAB integrates calculation, programming and visualization in a simple to use surroundings where mathematical expressions are used to express troubles and solutions. Because of all these qualities of MATLAB a system of number of numerical equations used for electrical modelling of bilayer organic solar cell are solved easily and in better way as compared to other programming languages. 3.9 References [1] B.

The Awakening :: Personal Narrative Essays

The Awakening As I strolled through the door of the old stone building of the Danish Folk High School in Sønderborg, Denmark, I had no inclination of what I was supposed to be thinking. From the moment when we arrived in Copenhagen, the concept of the Folk High School was thrown at us in many different ways and I, maybe still in a wary state of jetlag, never grasped it. When we first arrived, I could not fathom the concept of a high school student finishing their studies and, en-lieu of moving on to college, chooses instead to give up a precious year of his or her life to go to a folk high school. "A school with no grades?" I balked back at a professor of mine who was telling us of the origins of the schools, "why would anyone want to waste their time going to one of them?" It was with this preconceived stereotype of mine that I reluctantly entered the building. "Bizarre," I remember as the first word spoken from my lips to a friend of mine as we were gathered in a large group together in the school's auditorium for the opening lecture. "This place reminds me of the YMCA back in my home town," I added, trying to make a common ground with something I was very familiar with in my life. It was not that I was trying to put the school down on a first judgment, for the place did in fact remind me a great deal of my local Y. With it's small, cramped dorm-rooms, musty pool and locker-room facilities, and tiny, hardwood floor gyms, it's a wonder I did not break down in a fit of home-sickness. Through the entirety of the Principal's speech, I remember wondering back to my original thought of why a high-school graduate would want to go to one of these schools. The Principal only touched upon this pressing issue of mine from a very distant perspective. He noted how the Folk High School we were currently visiting had a sports oriented curriculum, and thus most of students went on to work as a trainer or a head coach of a particular sport. I was not that naïve to believe that of the ninety plus students currently enrolled in the school, all ninety would go on to a sports related job in their future.

Teaching Philosophy Statement :: Education Teachers Classroom Essays

Teaching Philosophy Statement â€Å"I touch the future. I teach.† Christa McAuliffe’s statement about touching the future is how I feel about teaching. Being passionate about teaching and wanting to help and inspire the youth of America is my philosophy. Teaching is not always thought of as the noblest career choice, but in my eyes it is. Without the inspiration of good teachers there would be no doctor, lawyers or other teachers. I agonized over the decision of what career path to take, but it all became so clear my senior year of high school. I thought of all the teachers who had inspired me in years past to do my best and not to give up, and that is when I decided I wanted to be a teacher. There were a few teachers that made me feel they really cared about my education and my future. That is the kind of teacher I strive to be. I hope I can inspire my students to do something great with their lives. Although I was happy with my decision everyone I told thought I was crazy to want to purs ue such a â€Å"thankless job† as they called it. I saw it in another light though; teaching is something I knew would be right for me. Teachers have the ideal work schedule I think. I may have some paper work to do or school functions to attend, but this job will allow me to spend time with my family. If I decided to have children this would allow me to have the quality time I want to spend with them also. Overall the positive aspects of teaching greatly out weigh the negative ones from my point of view. My major is physical education and health, which will allow me to teach something I am passionate about; physical fitness. I believe for a student to be well balance they have to feel good and feel good about themselves. In today’s society of video games and computers children are leading more and more sedentary lifestyles. As a P.E. teacher I hope to change that and teach kids healthy habits for long-term fitness. As part of the â€Å"New P.E.† generation I think the skill-based learning with be more effective than simply just letting kids play games that they don’t have the skill for.

Heroes and Cowards in A Farewell To Arms, by Ernest Hemingway :: A Farewell To Arms

   War creates only two types of men: heroes and cowards.   In the book, A Farewell To Arms by Ernest Hemingway, Mr. Frederic Henry was an American Lieutenant ambulance driver in the Italian Army. "The army was staying in Gorizia, a little town that had been captured by the Italian army" (5). The town looked across a river and the plains to the mountains. There was fighting going on in those mountains, only a mile away. One evening when Frederic came in the house after doing some work on his ambulance, his friend Rinaldi took him to a hospital to meet a nurse who was a friend of Rinaldi's. Frederic thought that Miss Barkley was very pretty and good looking. Frederic started seeing Miss Catherine Barkley on a regular basis. "Frederic got orders to take two ambulances and three other drivers and go to the war front, up the river in Plava" (54). They were to pick up as many of the wounded as they could and deliver them to the hospitals where their papers said to take them. When he got up to Plava late in the evening, Frederic found out that there was a plan for a military strike that night. They were ordered to stay there and wait for the strike to take place before they left, so they wouldn't get hit by the bombardment. All of the drivers were to stay in a dugout in the riverbank while the strike was going on. There was all kinds of gun fire and bomb shells being shot back and forth. "The drivers were all in the dugout eating noodles and cheese while drinking wine" (55), when a bomb shell hit the dugout, killing one of the drivers and wounding Mr. Henry as well as one of the other drivers. Frederic was hit in the legs by the objects that were in the bomb, one of his knees was blown down around his shin. One of the drivers took him to the medical tents to get bandages put on his legs until they could get him back to a hospital. "The army sent Frederic to an American hospital in Milan" (77). This hospital had just been built and they needed nurses there. The hospital in Gorizia transferred Miss Barkley to the hospital in Milan. She was one of the nurses looking after Frederic while he was in the hospital.

How Can We Explain the Difference in Achievement with Boys and Girls?

How can we explain the differences in achievement between boys and girls? Statistics show that it is clear that girls achieve more A* to C grades at GCSE then boys. This obviously shows that girls do better and achieve more in schools. In fact, since 1980 to the present day, the percentage of boys who have achieved these grades has risen. But so has the girls. When it comes to girls and boys choosing their options for GCSE, although they are open to pick the same subjects, there still seems to be a split. Girls tend to op for cookery, design technology and sociology. Whereas boys tend to op for resistant materials, P.E and science. So it is clear that there are the ‘boys’ and ‘girls’ subjects. One way the difference is shown in achievement is by setting and streaming in different schools. It is more common for girls to be placed in top set for all their subjects then it is for boys. Girls tend to do better in school then boys. This could be influenced by a t eacher (self- fulfilling prophecy). If girls and some boys are told that they are capable of getting great grades in school, then they are bound to achieve better than other students that are put in bottom set and are told they can only get a D or E, which are mostly boys.This shows that there is a difference between the achievement of boys and girls because girls are more likely to be placed in top set and are encouraged by their teachers to do well, whereas boys are not. Another way the difference is shown is by society and through the jobs that different gender roles take. There has been a divide in women and men jobs for a while. However now, there are increasing job opportunities for women. It is still known that women are more likely to take up jobs like nursing, caring, teaching and so on then it is for men.Men usually take up the job of mechanics, firemen, policemen etc. So in schools, they prepare the students for the job they believe is right for their gender. This shows t hat there are differences because boys must need to be more educated for the jobs they are required to get, whereas girls don’t need to be as much. If boys are ‘more’ educated then girls, then they are more likely to get better grades, but that still doesn’t explain why girls are achieving better than boys! Individual attitudes have a big impact on how a student achieves.Girls tend to always do their homework, always be well behaved and are in the pro- school subculture. Whereas boys tend to never do their homework, always misbehave and are in the anti-school subculture. This shows that girl want to do well in school to have a good life and a well-paid job, but it also shows that boys don’t really care about school and haven’t really thought about their future. This shows that there is a difference in achievement between girls and boys because girls have a better opinion of school and so will achieve better grades then boys as they have a neg ative opinion of school.It’s not that boys’ do less well. Boys’ achievement has been improving but girls have been improving more. All the matters that I have stated are linked. They all seem to state that girls achieve better in school than boys and that boys take their education for granted. There is also a link with boys and girls attainment. Boys tend to be at school less than girls and girls have better punctuality then boys. So, we can conclude that girls achieve better than boys because of their positive attitudes, actually wanting a good life and a good education.

Mrs Bennet’s character in ‘Pride and Prejudice’ Essay

Analyse Mrs Bennet’s character in ‘Pride and Prejudice,’ by looking closely at her attitude and behaviour. Comment on what you think Mr Darcy and Elizabeth think of her, as well as your own views. ‘She was a woman of mean understanding, little information, and uncertain temper.’ Mrs Bennet, the mother of five girls; Jane, Elizabeth, Mary, Kitty and Lydia, most resembles her youngest daughter, Lydia; a shallow and flirtatious girl. Similarly, Mrs Bennet is very excitable and pronounces her fondness for ‘red coats’ when she was Lydia’s age. This declaration of her affection is quite endearing and reveals Mrs Bennet’s younger side. Mrs Bennet and Lydia are the pinnacles of the kind of characters who talk far too much and fuss about silly things. An example demonstrating this aspect of her character is how Mrs Bennet does not worry herself with the moral consequences of Lydia’s ‘infamous elopement’ but fusses about trivial, frivolous things such as wedding clothes and ‘where the best warehouses are.’ This also demonstrates her stupidity and lack of insight into human nature which prevents her from realising how close Mrs Bingley comes to being outright rude. She believes that Mr Bingley’s sisters were ‘charming women.’ Then goes on to comment, ‘I never in my life saw anything more elegant then their dresses.’ Apart from being utterly wrong about them, she demonstrates perfectly her superficiality. She obviously is taken with the sisters because she sees them dressed incredibly ornately, and knows how rich they are, fogging her view of their personality. From the very beginning of the novel, Mrs Bennet comes across as a woman obsessed about marriage. The first event in the entire book is Mrs Bennet gossiping about a young man of good fortune, Mr Bingley, who has just moved into the area. Mrs Bennet is already planning for one of her daughters to marry Mr Bingley, even though she has never met him and doesn’t know anything about him apart from the he is ‘a single man of large fortune; four or five thousand a year.’ She says, ‘What a fine thing for our girls!’ This clearly shows that Mrs Bennet aims to get her daughters married to wealthy men, not minding if her daughter’s love them or if they are nice people or not. This demonstrates an element of foolishness especially as she of all people should know about the problems of such an ‘unsuccessful marriage.’ This, along with the evidence of Mrs Bennet’s silliness seems to suggest that Mr Bennet married Mrs Bennet for convenience and for her looks rather than for love and her personality. Their love-hate relationship relies upon her gullibility and moodiness, and his love of teasing her which keeps Mr him going. Their barely surviving relationship should have shown Mrs Bennet the defects of a marriage for money and convenience, but she has in fact not learnt anything. She is so determined that she even wants Elizabeth to settle for marrying Mr Collins. However, her actions could be seen in a very different light. Perhaps it demonstrates her true love for her daughters. Maybe she wants them to marry rich because when Mr Bennet dies they will not inherit the house or any money because they are girls. The law says that the next male relative has to inherit everything. For this reason Mrs Bennet feels that she needs to secure her daughters future, making sure that they are settled. Mrs Bennet cannot accept not having her way and uses the blackmail, ‘you have no compassion for my nerves’ when she is not granted what she wants. One instance when she uses this excuse is when Mr Bennet refuses to speak to Mr Bingley and invite him over. It is very important to Mrs Bennet that Mr Bingley comes over so that she can try and get one of her daughters married to him. But when Mr Bennet gets in the way of her plan by not visiting Mr Bingley, Mrs Bennet shows that she gets very annoyed. The fickle side of her character is displayed when Mr Bennet finally admits that he has seen Bingley. Mrs Bennet’s mood changes very suddenly and she immediately gets excited and becomes happier. She says, ‘How good it was of you, my dear Mr Bennet,’ showing that she is superficial and that her feelings quickly change, cheering up at the thought of being able to marry off one of her daughters. Although it could also be seen that she is just a very determined person, whose resolution is to get her daughters married. Her determination, however, is sometimes taken a step too far, especially when Jane was invited to Netherfield. Jane requested the carriage to take her to the estate, but Mrs Bennet, excited by the chance for Jane to get to know Mr Bingley better, insisted that she ‘had better go on horseback,’ because it seemed ‘likely to rain.’ Mrs Bingley was in fact hoping that it would start to rain, so that Jane would have to stay at Netherfield, therefore having more time to get to know Bingley. Despite her lack of intelligence, this shows a very shrewd, scheming side to her character forming a plan to keep Jane at Netherfield. Furthermore, she could even be interpreted as uncaring. When it does indeed start to rain, Mrs Bennet’s foolishness surfaces, as she comments on it being a ‘lucky idea’ of hers to have sent Jane on horseback. She shows no regard for Jane’s health, but on the contrary, smugly praising herself for the success of her cun ning plan. On the surface, she does not seem bothered about her daughter’s health, but is more concerned about the achievement of her life’s aim; getting her daughters married. In this respect she seems more aware of her responsibilities as a parent than her husband. Later, she finds out that Jane is unwell, but is not even slightly worried, saying, ‘I am not afraid of her dying. People to not die of trifling colds. She will be taken good care of.’ Despite her unconcerned exterior, I think it is likely that deep down she really does care about her daughters, even though her number one priority is always to get her daughters married. Evidence of her deep down affection for her daughters is when she goes to Netherfield and ‘would have been very miserable’ had she found Jane in any danger. Another redeeming feature of Mrs Bennet is that she is loyal, for example when she stuck up for Elizabeth after Mr Darcy had refused to dance with her. She tells Elizabeth to not dance with Darcy next time, even if he asks her. This is perhaps her way of comforting Elizabeth, because she probably understands that Elizabeth must have been offended. From this point onwards, Mrs Bennet’s impression of Darcy changes completely from being ‘much handsomer than Mr Bingley’ to being a most disagreeable, horrid man, not at all worth pleasing.’ Her attitude towards him changes completely, and she forgets that she ever liked him in the first place. This reveals her fickleness and superficial judgement. When she didn’t know him, she presumed that he was a really nice person just because she knew he was rich, but just as easily as she formed her first opinion of him, she changed her mind. Near the end of the novel she once again changes her opinion of Darcy. Although she has disliked him throughout the whole book, declaring that he is ‘so high and so conceited,’ she is overjoyed at the news of Elizabeth’s engagement to him. She again changes her mind starting to really like him. The rest of the family were worried that she had made the wrong decisions about Darcy and may have been forced to marry him, but Mrs Bennet was not even slightly worried about that. She was just extremely happy that Elizabeth had found a rich husband, and that she only had two more daughters to get married. Her changeability is also brought to surface through her opinion of Mr Collins. Mr Collins is Mr Bennet’s closest male relative, and so is destined to inherit Mr Bennet’s house after his death. According to the law, girls could not inherit anything after their father’s death and so Mr and Mrs Bennet were relying on the fact that they would bear a son. Unfortunately, after conceiving five girls it became obvious that the possibility of having a son was very unlikely, by when it was already too late to start saving money to pay their daughter’s dowry and provide for them for the future. Mrs Bennet particularly didn’t like Mr Collins for this reason, as she blames him for inheriting her house, even though it is not his fault. Even before she has met him or found out anything about him, she has already decided that he is an ‘odious man’, out for what he can get. She goes on to say to Mr Bennet, ‘If I had been you, I should have tried long ago to do something or other about it,’ referring to the fact that his estate has been entailed to Mr Collins. From this, it is apparent that Mrs Bennet blames Mr Bennet for their problems, not being clever enough to understand that it is the law and that there is nothing Mr Bennet could do about it. She proclaims that she ‘hates false friends,’ which is very judgemental of her, but when she realises that Mr Collins wants to marry one of her daughters, her attitude completely changes. She is no longer hostile towards him, and forgets about her grudge against him. However, Elizabeth, being much more sensible than her mother, refuses the offer of marriage because she understands that marriages without love do not work. She has seen her mother and father ‘passing’ their lives, not really understanding each other and sees ‘the defects of such a marriage.’ This decision agitates Mrs Bennet incredibly, who tells Mr Collins that Elizabeth ‘is a very headstrong, foolish girl and does not know her own interests; but I will make her know it.’ Mrs Bennets is very determined to have Elizabeth marry, and she suspects it would be quite had to get such as opinionated girl a husband. She is sure that she will be able to persuade or force Elizabeth to accept the offer of matrimony and doesn’t understand Elizabeth not wanting to marry Mr Collins or that they are incompatible. The way she sees it is that he has money, and will soon inherit Longbourne, so Elizabeth should accept the offer of marriage. This again seem s to suggest that she does not care about her daughter’s happiness but is more consumed with her own security for the future. Mr Collins, having given up on Elizabeth, marries Charlotte Lucas which outrages Mrs Bennet. She irrationally holds Sir William and Lady Lucas responsible for the whole situation, insisting that they must have convinced Elizabeth not to marry Mr Collins, an absurd idea showing how paranoid she is. She often passes blame onto other people, not accepting any responsibility for anything that goes wrong. She is so ‘vexed’ that she is impulsively rude to Sir William and Lady Lucas, spoiling their friendship because of her jealousy. Another aspect of her character is that she is very unsubtle and rude. Even though she spends most her time trying to find suitors for her daughters, she generally has the opposite effect and almost drives away suitors entirely. An illustration of her indiscretion is when she visits Jane at Netherfield. She believes that she is being very subtle in insulting Darcy, but in fact she is quite blatant with her insults and gives Darcy the impression that she is very loud in speech, foolish and insensitive. He is also offended by her lack of breeding and dislikes her since their first meeting at the Ball. He was annoyed at the way that Mrs Bennet would make judgements about people even without knowing them. She declares Mr Darcy to be ‘The proudest, most disagreeable man in the world.’ Without knowing him, Mrs Bennet had already made out his character, which annoyed him greatly. He also didn’t like the way that he would talk loudly about other people, thinking that this was insensitive and completely demonstrated her lack of breeding. He also considers her to be very foolish, and in his letter to Elizabeth he wrote that he tried to break Bingley and Jane up because of their class difference. He also commented on the fact that their mother was foolish, and so he could not let Bingley marry Jane. Elizabeth also considers her mother to be an embarrassment and very foolish. She thinks that her mother is insensitive and not very intelligent for example, when she sent Jane to Netherfield on horseback. Elizabeth was extremely worried about Jane and walked all the way to Netherfield to visit her sister. Her mother embarrasses her on many occasions such as when her mother misunderstands Mr Darcy’s comment on country people and reveals hostility towards him. This shows a lack of breeding and Elizabeth ‘blushes for her mother,’ trying to change the subject. The extreme diffence in character and sense between Elizabeth and Mrs Bennet makes Mrs Bennet look even more foolish and stupid. Mrs Bennet is like a literary caricature of an interfering matchmaker. Her faults are magnified to excessive proportions, making her character almost funny and therefore providing comic relief at tense moments in the play. Her role in the play is to be an obstacle which Darcy needs to overcome and accept in order to show that he truly loves Elizabeth. This is very difficult for Darcy as she is almost his complete opposite. She is silly, obsessive, hysterical and tactless, but in the end he accepts her because of his love for Elizabeth. In conclusion, Elizabeth, Mr Darcy and the reader may feel that Mrs Bennet is a foolish, insensitive woman, appearing to be loud, superficial and quickly irritated, but equally rapidly calmed down. This is because, throughout the novel, Jane Austin allows her more negative aspects to surface at different times throughout the novel by emphasising them through her words and actions. However, I feel that she is in fact a very caring and affectionate mother, who always has her daughter’s best interests at heart. Yet, this side of her personality is not often portrayed, forcing Mrs Bennet to be seen as an interfering, thoughtless woman.

Native Americans in the United States and Hardy Individualism Essay

Prompt: Although the development of the Trans-Mississippi West is popularly associated with hardy individualism, it was in fact largely dependent on the federal government. Assess the validity of this statement with specific reference to western economic activities in the 19th century. In the late 1800s and early 1900s, the idea of the far west captivated many. The chance to begin life anew attracted thousands of individuals and families alike to move out west and escape their current life, which was usually full of poverty and for some, full of discrimination. As the west expanded and grew into an important part of the United States, westerners found it somewhat difficult to survive with important resources going scarce. Although the development of the Trans-Mississippi west is mainly associated with hardy individualism, the westÂ’s development as a whole was largely the result of the aid of the federal government by constructing railroads, promoting and protecting the land, and removing the Indian tribes. Railroads were an integral part of the west; without them the West would not be successful. The distance of the west from the rest of the country was large and the only way to reach the west was through a long, tiresome journey by wagon. The Pacific Railroad Act of 1862 paved the way for the expansion of the railroads. The Act gave companies land to build railroads. The faster the company built the railroad, the faster they could get more land, which they usually sold for profit later on. The construction of the railroad benefitted many who were not living in the west, namely Chinese immigrants. With thousands of workers, railroad companies had to ensure their safety to prevent being sued and frowned upon by the public. To prevent that, railroad companies provided many necessities for their workers like shelter.

Pros and Cons of Kyoto Protocol Essay

Kyoto Protocol is an attempt of global community to encourage industrialized countries to lower on emissions of GHG (greenhouse gas) emissions was signed in 1997 and till date there are multiple debates going on whether or not it was a step to foster a global cooperation to address current environmental issues or just a governmental endeavor to take under control a free market spot. First, the protocol is seen as a starting point for effective collaboration aiming to achieve global good and face climate change (Hamish McRae). The journalist is sure that the deal has shown the commitment of countries to sacrifice their short-term needs at micro level in order to follow the â€Å"long-term global environmental aims†. In contrast, Kyoto Protocol is poorly designed and does not have any clear influences in perspective â€Å"unlike the Montreal Protocol, which had a clear objective and clear benefits†, notes the author. All things considered can help to draw a conclusion that the Protocol is rather controversial in its future perspectives but is a significant leap of â€Å"a wider global process of conservation† (Hamish McRae). Second, carbon is traded like any other commodity: the treaty expects the countries that do not exceed their carbon emissions limits to sell the surplus to the countries which due to their industrial needs are beyond the allocated quotas. On the other hand, â€Å"carbon market† has plenty of opponents ready to state that even though the carbon trading is being constantly advertized as a key solution to coping with climate change, it is just a small part of the dilemma. Tamra Gilbertson and Oscar Reyes are sure that â€Å"today’s climate challenges require a paradigm shift in our thinking and approaches† (3). The Carbon Trade Watch researchers state that the adoption of proposed schema was a way to â€Å"make climate problems fit market solutions† (9). In any case, despite its bright perspectives in reality Kyoto Protocol leaves very less room for adequate decisions in environment pollution control and gives a way to corporations and governments to speculate on their emissions targets. Third, it is worthy to take a look at nowadays situation and whether or not â€Å"Son of Kyoto† can be considered a success reaching its initial targets and objectives. The recent United Nations Climate Change Conference (COP18/CMP8) prolonged the lifeline of â€Å"of the Kyoto Protocol beyond 2012 keeps it alive as the sole legally binding plan for combating global warming† for eight more years (Alister Doyle and Barbara Lewis). This can be seen as a constant struggle of humanity to overcome or at least control the situation with growing GHG emissions in spite of all the imperfection and criticism of the Kyoto initiative. Some of Doha decisions were questioned by Russia as well as neighboring Ukraine and Belarus asking to â€Å"be allowed extra credit for the emissions cuts they made when their industries collapsed† (Roger Harrabin). However, the query was not given a credit which left Russia no room for objection. This fact claims that there is still no unity in common decisions and universal outlook on the problem of climate change preventive measures. On the whole, Kyoto Protocol is rather controversial instrument in global climate change arena. The deal should be taken as a serious step toward improving the future generations living conditions as well as preventing possible natural disasters. At the same time its coherence should be periodically reviewed and corrective actions taken based on the comprehensive scientific and environmental research not only on pure calculation and monetary estimates.
