Four Advantages of Single-Sex Schools

Research has shown that single-sex schools have many advantages for their students. On the whole, students educated in single-sex schools have more confidence than their coed peers and perform better academically. In addition, these students tend to not feel the pressures of gender roles and learn to pursue areas that interest them no matter what is considered socially acceptable for their biological sex. Though its impossible to make true generalizations about all same-sex schools, the following are commonalities of most of them. A More Relaxed Environment Even though many boys and girls schools demonstrate high standards of education, they often have more relaxed environments than their co-ed counterparts. These are cultivated in the absence of gendered desires to impress. When students are among peers that are physically similar to them, they do not feel as if they have to prove something about their biological sex, as is often the case for girls and boys in traditional schools. In addition to being true to themselves and behaving as they please, students in single-sex schools are more willing to take risks when they are not afraid of failing in front of the opposite sex. The resulting classrooms are often dynamic, free, and bursting with ideas and conversation—all hallmarks of a great education. Same-sex schooling also reduces the formation of cliques in some cases. With oppressive gender stereotypes and gender distraction out of the picture, students can concentrate on their studies and extracurriculars. Some experts say that this lack of pressure and competition gives rise to more welcoming attitudes toward peers of the same biological sex and the easier formation of platonic relationships as well. Less Gender Stereotyping Gender stereotypes rarely find their way into and impact same-sex schools, though they persist outside of them. In co-ed schools, students speak and behave in the interest of affirming their gender-related self-concept. In same-sex schools, this is a much less prominent issue and students worry less about whether their behavior is masculine or feminine enough for how theyd like to be perceived. Teachers in traditional schools tend to unconsciously (and unfairly) differentiate between males and females in their classroom when it comes to academics, behavior, and discipline—sex-segregated schools couldnt do this even if they wanted to. Overall, students in same-sex schools are less likely to feel pressured to act correctly in terms of cultural standards for their sex in the eyes of their teachers and peers. A Curriculum Tailored to Student Needs and Interests Some same-sex schools train their teachers in gender-specific teaching so that they can take full advantage of the opportunities a sex-segregated classroom affords. Same-sex schools make certain studies more productive and meaningful than co-ed schools. Teachers at all-male schools can teach books that speak to the male experience. A class discussion of Hamlet in these schools might involve studying the complicated formation of a young mans identity. In an all-female school, students can read books with strong heroines such as Jane Eyre to understand how womens lives are affected by prevailing attitudes toward their sex and how they prevail in spite of these. Carefully-selected topics can benefit students by speaking to the nuanced experiences of a single sex. Note that same-sex schooling only eliminates gender stereotypes when teachers do not make assumptions about the sex they teach. For example, a teacher in an all-male school can educate their students about how their bodies will change through puberty without making assumptions about their sexual orientation or gender identity. Teachers in all schools should only draw on what they know to be universally true of either sex and keep in mind that sex is not binary. Article edited by  Stacy Jagodowski

Breast Cancer And Its Effects On The World - 2813 Words

Breast cancer is a malignancy of the breast tissue, which can occur in both women and men. Worldwide, the most prevalent cancer in the world is breast cancer (4.4 million survivors up to 5 years following diagnosis). Global Scenario: It is estimated 1.67 million new cancer cases diagnosed in 2012 (25.2% of all cancers), with 5, 21,817 deaths accounting 14.7% mortality world over and ranks first overall (GLOBOCAN (IACR), 2014). It is now the most common cancer both in developed and developing regions (Jemal et al., 2011 Global cancer statistics). Incidence rates vary from 19.3 per 100,000 women in Eastern Africa to 89.9 per 100,000 women in Western Europe, and are high (greater than 80 per 100,000) in developed regions of the world (except†¦show more content†¦It is expected that in the coming decades, these countries would account for majority of new breast cancer patients diagnosed globally. Breast cancer cases are expected to increase by 26% by 2020 and most of these will be seen in developing countries (Anonymous, 2009). It is estimated that by 2030 the global burden of breast cancer will increase to over 2 million new cases per year (IARC, 2011) (GLOBOCAN, 2008).Such alarming statist ics of occurrence and mortality rates make it one of the most important health hazards. Indian Scenario: breast cancer is the most common malignancy among women with respect to incidence, frequency, and mortality (Yeole, 2008). According to recent IARC report, annual incidence of breast cancer in India is 1, 44,937 with a mortality of 90,659 (GLOBOCAN 2012). It is estimated that by 2030 the number of new cases of breast cancer in India will reach just under 200000 per year (Ferlay J, 2010). In the urban areas of India, cervical cancer had the highest incidence of cancer 15 years ago but has been overtaken by breast cancer as the most commonly diagnosed cancer among women (Pal and Mittal, 2004). As per the ICMR-PBCR data, breast cancer is the commonest cancer among women in urban registries of Delhi, Mumbai, Ahmedabad, Kolkata, and Trivandrum where it constitutes 30% of all cancers in females (National Cancer Registry Programme,

How Does The Carbon Cycle Work Environmental Sciences Essay Free Essays

The C rhythm can be defined as the uninterrupted biological procedure through which the C is exchanged between the environment and the beings. It besides refers to the thermonuclear reactions which are brought about by karyon of a C -12 atom when it absorbs protons. The sporadic clime alterations being experienced in the universe today are attributable to the break of C rhythm in one manner or the other. We will write a custom essay sample on How Does The Carbon Cycle Work Environmental Sciences Essay or any similar topic only for you Order Now Top of the possible causes of this break are human activities. States are loath to accept their portion of incrimination on the whole issue taking to a blasted game. Unless the universe unites against this common cause, the worst is expected to come. This paper covers the C rhythm, how it works and how it ‘s altering in response to human activities. Carbon is found in the ambiance in signifier of the C dioxide gas. Other ambiance gases which contain C dioxide include CFCs and methane. The deficiency or the improper operation of this rhythm can be really awful since workss and animate beings wholly depend on this rhythm during their major biological procedures. The work of the C rhythm can be evaluated or assessed in conformity to the different procedures that change or move C from one signifier to another. These procedures are viz. decomposition, photosynthesis, natural weathering of stones, respiration and the ignition of fossil fuels. During the procedure of photosynthesis C which remains in the ambiance as the C dioxide gas enters into the web of consumers and manufacturers or what is referred to as the ecological nutrient web. After its entry the photosynthetic beings ( algae, workss ) absorb the C dioxide through the bantam pores found in their foliages. Via photosynthesis the workss can now utilize the captive C dioxide an d change over it into simple sugars which are indispensable in the workss growing and reproduction. Plants besides pass C to the animate beings particularly when the animate beings feed o the workss since they do non hold the ability to do their ain nutrient ( Ryn and Cowan 87 ) . Respiration procedure is besides found in the C rhythm but it is unlike photosynthesis because it occurs in the decomposers, workss and animate beings. The respiration procedure besides produces C because the constituent of O is used in interrupting down organic compounds into the C dioxide gas and H2O. Through this procedure of respiration C atoms which start out as the compounds of C dioxide are absorbed through the organic structure of human being and so passed to the ambiance ready for another recycling. Decomposition happens to be the major procedure through which C is passed to the ambiance in signifier of C dioxide. This is achieved through the usage of decomposers ( microorganisms ) which are chiefly found in dirt and H2O. These decomposers normally take in dead and waste merchandises which are chiefly found in signifier of decomposing remains of animate beings and workss. At the same clip they release C dioxide through the procedure of respiration. As before stated, enduring of stones is the other procedure through which C atoms are released. For illustration the calcium hydroxide stone ( an ocean floor rock formed by marine plankton shells ) traps many C atoms. These C atoms are released sometimes after a million old ages when the ocean Waterss recede and the calcium hydroxide stone becomes exposed. Scientifically, it ‘s noted that when a calcium hydroxide stone is set out to the natural procedure of enduring it releases the already trapped atoms becomes a really active portion of the C rhythm one time. Human activities/processes besides increase the C dioxide in the ambiance. One of these activities is the burning of the fossils fuels. Due to the rapid enlargement of industrial revolution many people have been firing the fuels which contain oil and coal to power their engines. The changeless production of these fuels has resulted into immense sums of C dioxide in the ambiance. Most of the C dioxide produced by the burning of these fuels is nevertheless absorbed by workss, oceans and dirts therefore cut downing the increasing effects of planetary heating ( Scienceclarified.com 1 ) . The human activities that influence the C rhythm Human activities have greatly interfered with the procedures involved in the C rhythm. An illustration of these human activities is deforestation. Deforestation is the remotion of natural happening woods through cutting and firing of trees in any forested country. Peoples cut trees to utilize them as fuel, to utilize the land for grazing land, farming and to construct colonies. Active deforestation means that there will be no trees which emit O while devouring C constituents ( C dioxide ) . This leads to increased C dioxide than its consumed therefore destructing the C rhythm. The addition in C constituents in the air consequences into planetary heating ( inordinate warming o the Earth ‘s and oceans surface ) . This inordinate warming consequences into dried rivers or decreased volumes of H2O in the earths surface because the hydrological rhythm will be affected by higher rates of precipitation ( Miller 217 ) . Harmonizing to White ( 1203 ) , the ecologies have greatly been changed by overgrazing, terrassing, irrigation and the film editing of trees. For illustration he says that the Romans used to cut trees to construct ships which were used to contend Carthaginians. He besides states that the Bankss on the lower parts of the river Nile are now a human artefact alternatively of the African jungle which nature could hold created alternatively of adult male. He besides talks of historic ecological alteration which has been caused by the agricultural innovation. Farming prompts deforestation because there must be cutting down of trees to make more infinite for farming. This ecological alteration will be contributed by the addition of C constituents in the air since the forest screen is non available. The green house sort of agriculture is one of the major agricultural subscribers to the break of the C rhythm. This is because the green houses emit gases which are non utilised therefore conveyi ng about planetary heating. Some of the gases emitted include the signifier of C referred to as CFCs. It therefore transpires that the sum of the C produced is higher than the sums consumed. Another human activity which has contributed vastly to the break of the C rhythm is the burning of fuels. This is because of the increased combustion of fuels emits immense sums of C constituents. This will take to greater volumes of C dioxide in the air which will non be consumed therefore doing the C rhythm in effectual. White ( 1204 ) provinces that by 1925, London had experienced a smog job which was caused by the uninterrupted combustion of soft coal. He besides suggests that the current burning of fossil fuels is high up to the point of endangering to alter the universe ‘s ambiance as a whole. White besides suggests that war was another human activity which resulted in to ecological alterations including the break of the C rhythm. He asserts that the first cannon were fired in the early fourteenth century and this affected the ecology because workers were forced to the woods and mountains to scramble for more, S, potassium hydroxide, Fe ore and wood coal where by some res ulted into eroding and deforestation. He besides warns that a war fought with H bombs can change the genetic sciences of life. For illustration it will impact the procedures of the C rhythm between human existences and workss. Harmonizing to Mackenzie ( 1 ) , angling and whaling activities will impact the planetary C rhythm. This is because the uninterrupted remotion of the Marine biology has resulted into increased atmospheric C dioxide. She besides suggests that the rise of C dioxide or C has been caused by progressive fishing which has caused biomass depletion of the universe ‘s ocean. Nowadays, the marine productiveness is now comparatively lower than it used to be when there was a kept up C balance in the ocean-atmosphere. Another signifier of human activities which have influenced the flow of the C rhythm is air conditioning and infrigidation. This is because they utilize the C available in the air which is in signifier of CFC therefore suppressing the continuity of C rhythm between workss and animate beings. These human activities are nevertheless really of import in the universe because they cut down the effects of planetary heating by absorbing the excess C available in the air. Another huma n activity that has influenced the C rhythm is the transition of wild lands and agricultural lands into colonies. These human colonies are the major subscribers to the increased emanations of the planetary C dioxide. They affect the C rhythm through the direct emanations of the C dioxide ensuing from burning of fuels, the changes of the works and C rhythms during the transition of wild lands to urban and residential land screen and the indirect effects of urban and residential land screen on energy usage ecosystem C cycling. In human colonies the dirt C is lost through the dirt perturbations caused by the transition from natural to urban or sub-urban land screen type. The transition of good settled and managed land screen into human colonies consequences into higher rates of C segregation and storage due to big inputs of fertiliser, H2O and organic affair ( Pataki et al 1 ) .

Facebook s Influence On Facebook Essay Example For Students

Facebook s Influence On Facebook Essay I remember when my cousin introduced me to Myspace. I became obsessed with this website because it allowed me to find all of my friends from school. I could look at their pictures, their favorite song, which of their â€Å"top 10† friends were, and I could also message them. To me this was the most wonderful thing I had ever seen. I would pray I could get home sooner just to log on and see if I had missed any important post or if I had any new messages from friends. It was until a friend introduced me to Facebook that I realized Myspace wasn’t as great as I thought it was. It became my new fascination because I was in love with the idea of looking at my friends various interests, like their favorite movies, books, colors, authors, etc. Facebook allowed your profile to be a lot more personal. I found out things about my best friends that I didn’t even know until I saw their profile on Facebook and at times I doubted if I really knew them. There were days that I would find myself on Facebook for hours, lurking from profile to profile and judging people from their status and wall posts. By the age of 19 I had about 1,000 â€Å"friends† on Facebook, but I only spoke to about 50 or so. I knew a lot of those friends I had but I would never speak to them outside of the comfort of Facebook. At one point, I had strangers sending me messages and asking how I knew them and why I had added them. Most if the time I had no idea of how or why I had requested to be their friends, yet I still managed to have a conversation with them. I found myself talking to my friends more on Facebook than at school. Socializing was made easier through Facebook and we saw this as a good thing, but in reality it just made us more uncomfortable when it came to having a con. . tion. We don’t have to post everything we do through out the day. We don’t have to share our feelings to the world only to get hurt by them. This way of life isn’t satisfying. We are not meant to communicate through any kinds of screens. We have a voice for a reason and lately we don’t use it. We’re afraid of being judged for the sound that our mouth makes when we speak. We’re afraid of saying the wrong things, which is why we type and re-read what we typed at least 10 times before we hit send. We are becoming into â€Å"over thinkers†. But we forget the old saying, â€Å"Over thinkers get depressed.† I live this quote every day. I voice my opinion even if I get judged. I also tweet and post my opinion, and I like to talk about my feelings on Twitter all the time. Nothing beats a face to face conversation with my best friend though. FaceTime will never be able to replace her.
