Boys and Girls

...Commentary of “Boys and Girls” by Alice Munro Alice Munro is a Canadian short-story writer. She grew up in a rural environment such as is featured in the story “Boys and Girls”. This story is collected in her first collection of short stories, “The Dance of the Happy Shades”, which has been published in 1968. In the story, the protagonist experiences a process in which she leaves childhood. However, if we have to sum up the main idea of the text in a sentence, it would be the title with a few words more, “The education in boys and girls”. Therefore, we can see that the whole text is subordinate to this concept: characters’ attitude, characters’ comments, character’s name, indeed the style and the horses that appear in the story. Firstly, we will focus on the style. It is a first person narrator who shows us all the thoughts and impressions of the protagonist, this fact help us to understand how the influence of the other characters affects her. Secondly, we have to stress two characteristics of the personages that normally have unimportant role. One feature is the character’s names or more specifically the lack of name in some of them, because no female characters have a name, neither the main, so this fact helps to emphasize the distinction between women and men. Although neither the father has name, this could be explained in the sense that the author wants to stress that Laird, the son, is the winner because this sexist education is favorable to the men side. The other...

Boys and Girls

...ENG/125 July 16, 2012 Literature in Society In the story "Boys and Girls" by Alice Munro, she tells a story about a young girl whom resists womanhood during the time of society where men and women were not considered equal. A mother’s role was in the house and a man’s was outside the house. Men were the dominant figures in the household whereas the women were subservient. This story occurs on a family farm outside Jubilee, Ontario, Canada during the 1940s. Munro's narrator has no identity and therefore remains unnamed, compared to her younger brother Laird. Her brother's name, which is a synonym for "Lord," comes from a Scottish origin (Laird - Origin and Meaning, 2012). Munro uses these names to represent how a male child was more important than a female child in a family. The narrator resisted the role a woman was expected in life to lead. She worked outside with her father rather than inside the home with her mother. "I hated the hot dark kitchen in the summer" (p. 775). Because the narrator was female, she was not regarded as essential help to her father. "Could of fooled me," said the salesman. "I thought it was only a girl" (p. 774). She was still under appreciated even though she could work more than her younger brother. "Wait till Laird gets a little bigger, then you'll have a real help" (p. 775). This shows that girls were expected to stay inside the home doing chores whereas boys were allowed out to do the things that they wanted instead. ...

Boys and Girls

...Boys and Girls Recent history boldly notes the protests and political unrest surrounding the Vietnam Conflict during the 1960s and 70s. However, equally important in this era are the women who pushed for gender role and publicly rebelled against the established social norm of a woman's "place." Although Alice Munro may not have been burning her bra on the courthouse steps, threads of a feminist influence can be found in "Boys and Girls." Munro's main character, a girl probably modeled after Munro's own childhood experiences on an Ontario farm, faces her awakening body and the challenge of developing her social identity in a man's world. "The girl," an unnamed character, acts as a universal symbol for the initiation of a girl into womanhood. Through first-person narrative, Munro shoes the girl's views of her budding femininity and social identity by describing the girl's conceptions of her parents' work, her parallel to the wild mare Flora, and the "mysterious alterations" (Munro 474) in her personal nightly stories. As if to forsake her femininity and forego a life of confinement and housework, the girl reveres her father's work and condemns her mother's duties. The sum of the girl's respect seems to lie with her father, as is evident in her reference to his work outdoors as "ritualistically important" (468). On the other hand, while the girl recognizes that her mother is busy, she still considers her mother's "work in the house [to be] [·] endless, dreary and peculiarly...

Girls and boys meet old-fashioned standard and way of thinking early, which trip up for the single free challenge – in kindergarten, school and the surrounding society. It is not just restricted for the single person, it also means, that we e.g. get a very gender-segregated education system. Four out of ten choose educations, where more than 75% are one gender. That means, that we don’t get all talents in the game, and the Danish labour market gets very inflexible. More than 40% of all educations have got more than 75% of one gender. Over 99% of the students in the bricklayer-, paver-, and carpenter educations are men. Women dominate the educations for midwifes-, dental clinic assistant-, and sick nurse.

Boys Against Girls

...Boys Against Girls Summary: Discusses the academic and social rivalry between boys and girls. Findings of a study conducted by the American Association of University Women regarding the issue; Gap between men and women in the sciences; Strengths and weaknesses of boys and girls. GENDER A 1992 study by the American Association of University Women reported that schools shortchange girls--letting them lag behind boys in science, silencing them in class and damaging their self-esteem. But some experts are arguing that it's boys who lose out. "The Columbine killings have been a wake-up call," says Judith Kleinfeld, Ph.D., professor of psychology at the University of Alaska at Fairbanks. "Boys also have their problems." Kleinfeld refutes the findings of the AAUW study: With the exception of the (rapidly narrowing) gap between men and women in the sciences, she says, "most of the other findings are misleading or false." Studies show, for example, that girls receive better grades and more awards than their male counterparts. They also have superior verbal skills and are more likely to attend college. But while many schools sponsor interventions to coach girls in physics and math, few have tried to remedy boys' poor reading and writing abilities. And contrary to popular belief, many boys have a well-hidden low self-esteem, believing that schools are hostile towards them. "Women have been shortchanged in other areas of life," says Kleinfeld. "But schools, with their...

Sexism In Boys And Girls

...The Effects of Sexism in “Boys and Girls.” The world is a place where everyone calls “home” but is it really considered a home when sexism exists everyday? When someone thinks about home, it is a place where a person can do anything without being judged or told what to do. Everyone is a human being but why is it that sexism gets to decide what a person's role is? In society, people are “labelled” to do specific tasks because of their gender. Sexism is the main social issue that should not restrict what a gender can or cannot do. There are three main effects of sexism that restricts what a gender can do or cannot do and the three effects are sexism in the work force, roles of the household, and how males and females are portrayed as.

Every day the epidemic if violence grows either by the statistics of death of young black male, the inner city kids mastering the street, and social influences. A teenage boy pointed a gun in his face on the street, the worst part was his father beat him for letting himself get robbed by a boy. Recently they were a statistic report that shows how young people died. 24,600 people died as the victims of homicides. This converts into a homicide percentage of 8.9 per 200,000 populace. The homicide percentage for male teenagers ages 13-21 is 21.8 per 100,000. The homicide percentage for young African American males in this age group is 84.8 per 100,000. The overall homicide percentage for male teenagers in the US was between 6 and 83 times greater than the homicide percentage for male teenagers in any other nation.

A Word to the Resourceful

...January 2012 A year ago I noticed a pattern in the least successful startups we'd funded: they all seemed hard to talk to. It felt as if there was some kind of wall between us. I could never quite tell if they understood what I was saying. This caught my attention because earlier we'd noticed a pattern among the most successful startups, and it seemed to hinge on a different quality. We found the startups that did best were the ones with the sort of founders about whom we'd say "they can take care of themselves." The startups that do best are fire-and-forget in the sense that all you have to do is give them a lead, and they'll close it, whatever type of lead it is. When they're raising money, for example, you can do the initial intros knowing that if you wanted to you could stop thinking about it at that point. You won't have to babysit the round to make sure it happens. That type of founder is going to come back with the money; the only question is how much on what terms. It seemed odd that the outliers at the two ends of the spectrum could be detected by what appeared to be unrelated tests. You'd expect that if the founders at one end were distinguished by the presence of quality x, at the other end they'd be distinguished by lack of x. Was there some kind of inverse relation between resourcefulness and being hard to talk to? It turns out there is, and the key to the mystery is the old adage "a word to the wise is sufficient." Because this phrase is not only overused...

Why Girls Outpreform Boys

...Since the early 1990’s, girls have begun to outperform boys at most levels of the educationsystem. According to Pirie in Item A, the modular courses and continuous assessment found ineducation today has been seen to favour the systematic approach of girls, compared to the oldO level exam which typically favoured boys. These changes within the education system are seenas the main result of gender differences in education, nevertheless, external factors such asthe impact of feminism and changes in the job market may also have influenced the increase ingirl’s attainment.Firstly, it may be argued that the way pupils are assessed has favoured girls and disadvantagedboys. Gorard found that the gender gap in achievement was stable from 1975 up until 1988 whenit increased rapidly. This was when GCSE and with it coursework was introduced. Mitsos andBrowne support the view that GCSE’s favoured girls as they were more successful in courseworkdue to the fact that girls are seen to be more careful with their work, more likely to spendlonger on their work and meet deadlines. However, Ellwood argues that although coursework hashad some influence, exams themselves have a greater influence in the final grade. Thereforethis does not create a significant gap between gender differences.Secondly, the way in which teachers interact with pupils differs. Sociologist Jane and PeterFrench argue that classroom interaction between teachers and boys was not that different tothat of girls in terms of academic...

...false hope. “Boys and Girls” by Alice Munro is an excellent example that indicates that people’s reality can get tangled up with their dreams. Similarly, “A Handful of Dates” by Tayeb Salih is also a brilliant example of dreams versus reality. Although, there are obvious differences between “Boys and Girls” and “A Handful of Dates”, they still have many similarities. Both stories demonstrate that a person’s in this case the protagonist, can easily be engrossed in a dream or illusion, causing conflict which can lead to personal growth through dreams, conflicts and symbols.

Boys and Girls Left Alone

...Outline of “Letters to the Editor” There are two letters one from each side of two different views on filming children left alone, making their own decisions on living life, and then broadcasting it. There is one pro the idea and one against it. The letter pro the idea comes from Andrew Mackenzie, head of factual entertainment and he writes that every show that is broadcasted had to follow Ofcoms’ guidelines. That means that the children were in good hands throughout the whole program. The parent was always nearby and had the opportunity to intervene whenever they wanted, and withdraw their kid from the program. This gave the parents the insight on their kids’ behaviour when they are not around. The opposite letter was written by Dr Richard House, Senior lecturer in psychotherapy from Roehampton University. He makes it clear in his letter that it is impossible to secure the inner environments for any people no matter who you are, especially children. The psyche of children is very fragile, and is not to be toyed with. Andrew Mackenzie also states that all of the children participating were carefully casted and screened by experts so that the children could cope the whole situation and experience. The parents had access to advice and support at any time needed, and all safety measures were taken care of. The children’s wellbeing were at all time the top priority. As an answer to that Dr Richard House states that it is simply impossible to select and pick out children that...
