Neo-Colonialism, the Last Stage of imperialism by Kwame Nkrumah - 0 views

    • wstrahan
       
      Neo-colonialism isn't a problem until it's being used to impoverish less developed countries, rather than help develop them.
  • Non-alignment, as practised by Ghana and many other countries, is based on co-operation with all States whether they be capitalist, socialist or have a mixed economy. Such a policy, therefore, involves foreign investment from capitalist countries, but it must be invested in accordance with a national plan drawn up by the government of the non-aligned State with its own interests in mind.

      Countries like Ghana choose not to align with an economic policy like capitalism or socialism in order to trade with all countries based on their own national plan.

  • The growth of nuclear weapons has made out of date the old-fashioned balance of power which rested upon the ultimate sanction of a major war. Certainty of mutual mass destruction effectively prevents either of the great power blocs from threatening the other with the possibility of a world-wide war, and military conflict has thus become confined to ‘limited wars’. For these neo-colonialism is the breeding ground.
    • wstrahan
       
      Nuclear weapons have increased the growth in neo-colonialism. Larger economic countries such as the U.S. and Russia would rather avoid a world war and nuclear mass destruction by fighting "limited wars"
  • Limited war, once embarked upon, achieves a momentum of its own. Of this, the war in South Vietnam is only one example. It escalates despite the desire of the great power blocs to keep it limited. While this particular war may be prevented from leading to a world conflict, the multiplication of similar limited wars can only have one end-world war and the terrible consequences of nuclear conflict.
  • Neo-colonialism is also the worst form of imperialism. For those who practise it, it means power without responsibility and for those who suffer from it, it means exploitation without redress.
  • In the days of old-fashioned colonialism, the imperial power had at least to explain and justify at home the actions it was taking abroad.
  • Neo-colonialism, like colonialism, is an attempt to export the social conflicts of the capitalist countries.
  • The problem which faced the wealthy nations of the world at the end of the second world war was the impossibility of returning to the pre-war situation in which there was a great gulf between the few rich and the many poor. Irrespective of what particular political party was in power, the internal pressures in the rich countries of the world were such that no post-war capitalist country could survive unless it became a ‘Welfare State’. There might be differences in degree in the extent of the social benefits given to the industrial and agricultural workers, but what was everywhere impossible was a return to the mass unemployment and to the low level of living of the pre-war years.
  • In the past it was possible to convert a country upon which a neo-colonial regime had been imposed — Egypt in the nineteenth century is an example — into a colonial territory.
  • The essence of neo-colonialism is that the State which is subject to it is, in theory, independent and has all the outward trappings of international sovereignty. In reality its economic system and thus its political policy is directed from outside.
  • e, but neo-
  • Where neo-colonialism exists the power exercising control is often the State which formerly ruled the territory in question, but this is not necessarily so. For example, in the case of South Vietnam the former imperial power was France, but neo-colonial control of the State has now gone to the United States.
  • The neo-colonial State may be obliged to take the manufactured products of the imperialist power to the exclusion of competing products from elsewhere. Control over government policy in the neo-colonial State may be secured by payments towards the cost of running the State, by the provision of civil servants in positions where they can dictate policy, and by monetary control over foreign exchange through the imposition of a banking system controlled by the imperial power.
  • The control of the Congo by great international financial concerns is a case in point.
  • The struggle against neo-colonialism is not aimed at excluding the capital of the developed world from operating in less developed countries. It is aimed at preventing the financial power of the developed countries being used in such a way as to impoverish the less developed.
  • The result of neo-colonialism is that foreign capital is used for the exploitation rather than for the development of the less developed parts of the world. Investment under neo-colonialism increases rather than decreases the gap between the rich and the poor countries of the world.
  • The system of neo-colonialism was therefore instituted and in the short run it has served the developed powers admirably. It is in the long run that its consequences are likely to be catastrophic for them
  • Neo-colonialism is based upon the principle of breaking up former large united colonial territories into a number of small non-viable States which are incapable of independent development and must rely upon the former imperial power for defence and even internal security. Their economic and financial systems are linked, as in colonial days, with those of the former colonial ruler.
  • In the neo-colonialist territories, since the former colonial power has in theory relinquished political control, if the social conditions occasioned by neo-colonialism cause a revolt the local neo-colonialist government can be sacrificed and another equally subservient one substituted in its place.
  • The introduction of neo-colonialism increases the rivalry between the great powers which was provoked by the old-style colonialism. However little real power the government of a neo-colonialist State may possess, it must have, from the very fact of its nominal independence, a certain area of manoeuvre. It may not be able to exist without a neo-colonialist master but it may still have the ability to change masters.
  • The ideal neo-colonialist State would be one which was wholly subservient to neo-colonialist interests but the existence of the socialist nations makes it impossible to enforce the full rigour of the neo-colonialist system. The existence of an alternative system is itself a challenge to the neo-colonialist regime. Warnings about ‘the dangers of Communist subversion are likely to be two-edged since they bring to the notice of those living under a neo-colonialist system the possibility of a change of regime.
  • In fact neo-colonialism is the victim of its own contradictions. In order to make it attractive to those upon whom it is practised it must be shown as capable of raising their living standards, but the economic object of neo-colonialism is to keep those standards depressed in the interest of the developed countries.
  • Their manufacturers naturally object to any attempt to raise the price of the raw materials which they obtain from the neo-colonialist territory in question, or to the establishment there of manufacturing industries which might compete directly or indirectly with their own exports to the territory.
  • In the end the situation arises that the only type of aid which the neo-colonialist masters consider as safe is ‘military aid’.
  • Once a neo-colonialist territory is brought to such a state of economic chaos and misery that revolt actually breaks out then, and only then, is there no limit to the generosity of the neo-colonial overlord, provided, of course, that the funds supplied are utilised exclusively for military purposes.
  • Military aid in fact marks the last stage of neo-colonialism and its effect is self-destructive. Sooner or later the weapons supplied pass into the hands of the opponents of the neo-colonialist regime and the war itself increases the social misery which originally provoked it.
  • Nowhere has it proved successful, either in raising living standards or in ultimately benefiting countries which have indulged in it.
  • This book is therefore an attempt to examine neo-colonialism not only in its African context and its relation to African unity, but in world perspective. Neo-colonialism is by no means exclusively an African question. Long before it was practised on any large scale in Africa it was an established system in other parts of the world
  • ‘The industrial nations have added nearly $2 billion to their reserves, which now approximate $52 billion. At the same time, the reserves of the less-developed group not only have stopped rising, but have declined some $200 million. To analysts such as Britain’s Miss Ward, the significance of such statistics is clear: the economic gap is rapidly widening “between a white, complacent, highly bourgeois, very wealthy, very small North Atlantic elite and everybody else, and this is not a very comfortable heritage to leave to one’s children.”
  • ‘For the vast majority of mankind the most urgent problem is not war, or Communism, or the cost of living, or taxation. It is hunger. Over 1,500,000,000 people, some-thing like two-thirds of the world’s population, are living in conditions of acute hunger, defined in terms of identifiable nutritional disease.
  • What is lacking are any positive proposals for dealing with the situation. All that The Wall Street Journal’s correspondent can do is to point out that the traditional methods recommended for curing the evils are only likely to make the situation worse.

Stem Cell Research at the Crossroads of Religion and Politics | Pew Research Center's R... - 0 views

  • For patients and their families, embryonic stem cell research offers the hope of cures for chronic and debilitating conditions, such as juvenile diabetes, Alzheimer’s disease, Parkinson’s disease, spinal cord injuries and blindness. For scientists, it represents a revolutionary path to discovering the causes and cures for many more human maladies. Embryonic stem cells are pluripotent, that is, they have the unique ability to develop into any of the 220 cell types in the human body. In addition to their versatility, embryonic stem cells are easier to grow in the laboratory than adult stem cells.

  • For the Catholic Church and many other Christian groups, life begins at conception, making the research tantamount to homicide because it results in the destruction of human embryos. “Human embryos obtained in vitro are human beings and are subjects with rights; their dignity and right to life must be respected from the first moment of their existence,” the late Pope John Paul II wrote in his 1995 encyclical, The Gospel of Life.

  • National polls indicate that a slim majority of Americans support the research. According to a 2007 national poll by the Pew Forum on Religion & Public Life and the Pew Research Center for the People & the Press, 51 percent say it is more important to conduct stem cell research that could result in new medical cures than to avoid destroying the potential life of human embryos. The same poll found that 35 percent say it is more important not to destroy embryos.

      This is very important data about Americans support of stem cell research. The previous highlighted region in this article said that many Christians aren't in favor of stem cell research, yet the national polls indicate otherwise. So it can be inferred that some Christians are in favor of stem cell research, to the point of where there is a slim majority of Americans in support of the research. This may proof to be a definite curve ball in an argumentative research inquiry paper.

  • While these states have taken action to move forward on stem cell research, the issue is unsettled in much of the country. Because the U.S. government allows the research as long as no federal money is spent, state universities and private, nonprofit and corporate laboratories are free to pursue it, except in states that prohibit it.

  • An accidental president, who came to power because of Anwar Sadat's assassination on October 6, 1981, Mubarak initially calmed the public, stressed the rule of law, released political prisoners and encouraged parliamentary elections. However, as soon as he began his second term, in 1987, he refused to reform the constitution, extended the state of emergency, promulgated laws to exclude opposition parties from local councils and tightened the grip of the ruling National Democratic Party (NDP) over parliament. He denounced opposition groups for criticizing his policies and asserted, threateningly, "I am in charge, and I have the authority to adopt measures…. I have all the pieces of the puzzle, while you do not."1
  • after the Islamist groups renounced violence in 1997, emergency and military courts continued to operate. They prosecuted civilians charged with nonviolent infractions, such as Muslim Brothers who met to prepare for professional syndicate elections or journalists who "slandered" regime figures. Police increasingly harassed people on the street, demanding bribes from shop owners and minivan drivers and free food from vendors and restaurants. They seized and beat people in order to coerce false confessions or to pressure them to become informers. They harassed people who came to the police station to get IDs or other routine documents, and they nabbed those who "talked back" to them. Amnesty International concluded that torture was "systematic in police stations, prisons and [State Security Investigations] SSI detention centers and, for the most part, committed with impunity…. [Security and plainclothes police assault people] openly and in public as if unconcerned about possible consequences."

  • 3 Even the government-appointed National Council on Human Rights, in its first annual report (2004), expressed deep concern about the 74 cases of "blatant" torture and 34 persons who had died in police or SSI detention that year.4 A U.S. diplomat cabled in 2009 to Washington that Omar Suleiman, director of the Ge
  • neral Intelligence Directorate, and Interior Minister Habib al-Adly "keep the domestic beasts at bay, and Mubarak is not one to lose sleep over their tactics."5
  • All aspects of public life were controlled, ranging from censorship of cultural and media production to the operation of labor unions.
  • Workers were banned from striking and, since the change in the labor law in 2003, were often hired on short-term contracts, under which they had no medical — or social — insurance benefits. The monthly minimum wage had not been raised since 1984, when it was set at LE 35 (in 2011 the equivalent of $6).6 The ETUF enforced government policy rather than represented its millions of members.
  • Private-sector workers suffered even more, as the 2003 labor law failed to provide any protection to employees negotiating length of contract, salary level, hours at work, overtime compensation, vacation or lunch breaks. Workers often lacked health and injury insurance. Many private-sector firms forced new hires to sign, along with the contract, Form No. 6, which allowed the employer to fire them without warning, cause or severance pay.
  • The exclusion of opposition forces from the political arena in fall 2010 was accompanied by systematic crackdowns on the media, cultural expression and university life. The regime wanted to prevent critical commentary from being aired in independent newspapers and on private satellite stations. The government closed down 19 TV and satellite channels, hacked or blocked several websites, and pressured private businessmen to cancel outspoken critics' positions as editors, opinion writers and talk-show hosts. The Association for Freedom of Thought and Expression (AFTE) concluded: "The Ministry of Mass Media and Communication has tightened its fist over all media channels to markedly reduce the space for freedom of expression, especially [during and] after the last parliamentary elections."13
  • Already, press and cultural output were managed through myriad control boards. Journalists were beaten, jailed and/or fined if they investigated corruption or police brutality and were charged with incitement or libel when they criticized government policies or political leaders. AFTE also reported heavy-handed censorship of movies, plays and books.
  • The crackdown on university life accelerated after the 1979 student charter was amended in 2007 to give administrative bodies — and, behind them, the SSI — the right to bar students from running in university elections. By th
  • en, the SSI was interfering deeply in university operations: approving the appointment of rectors and deans, exercising a veto over teaching-staff employment and promotions, vetting graduate teaching assistants, determining the eligibility of students to live in dormitories, and interfering in scientific research, textbooks choices, and faculty permissions to travel abroad to participate in conferences.14 The SSI presence was overtly threatening; guards stood at the gates and at each building. Plainclothes SSI officers quelled demonstrations as well as threatening and arresting student activists. Then, in October 2010, the government refused to implement the Supreme Administrative Court ruling that banned SSI guards from the campuses and also blocked anti-regime candidates from contesting seats in the student-union elections.15

  • Given the overwhelming power of the state, the severe restrictions imposed by the State of Emergency on public gatherings, and the unchecked violence by police and security forces, people were fearful of protesting in the streets. Nonetheless, there were many efforts to expose the conditions. Novels and films highlighted corruption, police brutality, urban poverty and sexual harassment.29 Some art exhibits displayed in-your-face paintings depicting torture and military repression. Human-rights groups reported on poverty in the countryside and cities, deteriorating environmental conditions, harassment of women and activists, restrictions on the press, police coercion, and thuggery during elections.
  • There was public outrage at the very public beating-to-death just before midnight on June 6, 2010, of 28-year-old Khaled Said, seized as he entered an internet café in Alexandria.35 Late that night 70 young men and women gathered across from the police station, demanding that the police be brought to justice. They received the usual response: beaten, dragged along the street, attacked by police dogs, and arrested. Protests continued throughout the summer: funeral prayers at Sidi Gaber mosque, attended by 600 mourners who spilled out into the street afterwards; a vigil outside the Ministry of Interior headquarters in Cairo; a silent protest along waterfronts and bridges throughout Egypt; and numerous violently suppressed protests in downtown areas not only involving well-known politicians and protest groups but also people who felt that Khaled Said could have been themselves, their son, or their grandson. A teenager reflected this perspective, saying: "This is an extraordinary case. This guy was tortured and killed on the street. I did not know him but I cannot shut up forever."36 "For the sake of Khaled! For the sake of Egypt!" (ashan Khalid, ashan masr) became a rallying cry, voiced in fear as well as in the determination to restore individual and collective dignity (karama). On the fortieth day commemorating his death, people shouted outside the High Court: "Our voices will not be silenced… We've waited for 25 years, but our condition has not improved. Tomorrow the revolution will come."37
  • Dozens of Facebook groups supported the cause, of which "We Are All Khaled Said" became the most famous. They circulated reports about poli
  • ce brutality, many of which had been posted in the past but had not received such intense scrutiny. These included the video of police sodomizing a 21-year-old minivan driver in January 2006. Filmed by police officers in Boulaq al-Dakrour station, the police mailed it to the cell phones of other van drivers to intimidate them. "Everybody in the parking lot will see this tomorrow," they boasted.38 Hafez Abu Saeda, head of the Egyptian Organization of Human Rights, noted: "Police brutality is systematic and widespread… The humiliation of the simple citizen has become so widespread that people are fed up."39 Their anger, he warned, could spark a rebellion.
  • Nonetheless, the protesters themselves agree that it took the swift removal of Ben Ali to make them think that, if sudden change was possible in Tunisia, it might be possible in Egypt.
  • Even when people broke the barrier of fear on January 25, played cat-and-mouse with security forces on downtown streets on January 26 and 27, and withstood the onslaught all day and night on January 28, they faced a formidable regime, supported by the security forces and the entrenched NDP. The revolution would have been much bloodier if the armed forces had stood by the president. President Mubarak and Interior Minister Habib al-Adly hastened their own demise by unleashing extreme violence on January 28, followed by Adly's abrupt withdrawal of all police forces that night. Enraged, the public created neighborhood watches to ensure the safety of their communities.
  • Mubarak miscalculated by ordering the armed forces into the streets, even though their loyalty was to the nation — not to the person. He further miscalculated that he could offer minor concessions — such as appointing a vice president, changing the prime minister, and saying that he would not seek another term — on January 28 and again on February 1 and yet follow those placating words by unleashing fierce attacks on February 2. Over the next week, protesters held their ground, thousands of people flooded to city squares to call for dignity and freedom, labor strikes spread, employees in public institutions joined the movement, and lawyers, doctors, and professors marched in their professional garb. Finally, the Supreme Council of the Armed Forces ended its silent watch and forced Mubarak's hand. When Mubarak resisted leaving, the generals compelled the newly-appointed vice president to inform the president that, if he didn't step down, he would face charges of high treason.
  • Suddenly on Friday, February 11 — as millions of people surged angrily through the streets — Mubarak vanished. Anger transformed into tears of joy and celebration. And the next morning, young people cleaned up the public spaces, symbolically starting the huge task of cleansing Egypt of the corrupt regime and rebuilding the country. How they would rebuild Egypt remained uncertain, but their mobilization instilled a new and powerful pride, coupled with determination to take control over their future and not be cowed again by any authoritarian ruler.

How the Media Affects the Self Esteem and Body Image of Young Girls | Divine Caroline - 0 views

  • The medias harmful affect on the self body image and self esteem of young girls has brought about some of these three damaging effects: eating disorders, mental depression, and physical depression.
    • braxtondn
       
      It is interesting and sad knowing that new media has this affect on young teens. Something should be done in order to help prevent such negative affect. The media needs to recognize that everybody will come in different shapes and sizes, instead of just focusing on one specific image.
  • “Women may directly model unhealthy eating habits presented in the media, such as fasting or purging, because the media-portrayed thin ideal body type is related to eating pathology”(Stice, Schupak-Neuberg, Shaw & Stein, 1994)
  • In Allie Kovar’s article, Effects of the Media on Body Image, she mentions that “the national eating disorder Association (2006) reports that in the past 70 years national rates of incidences of all eating disorders have dramatically increased across the board . . . Bulimia in women between the ages of 10 to 39 has more than tripled.” (Kovar, 1).
    • braxtondn
       
      The media's "thin ideal' is causing young teens to feel so poorly about themselves that it is causing more women to become diagnosed with eating disorders. There is no reason that the media should be having that much of an affect on teens that it is tripling the amount of eating disorders. The media ( actresses, models, and celebrities) should be looked upon by their success not by their body image.

Speed of light - Wikipedia, the free encyclopedia - 0 views

  • The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its value is exactly 299,792,458 metres per second, a figure that is exact because the length of the metre is defined from this constant and the international standard for time.[1]
  • The first quantitative estimate of the speed of light was made in 1676 by Rømer (see Rømer's determination of the speed of light).[83][84] From the observation that the periods of Jupiter's innermost moon Io appeared to be shorter when the Earth was approaching Jupiter than when receding from it, he concluded that light travels at a finite speed, and estimated that it takes light 22 minutes to cross the diameter of Earth's orbit. Christiaan Huygens combined this estimate with an estimate for the diameter of the Earth's orbit to obtain an estimate of speed of light of 220000 km/s, 26% lower than the actual value.[105]
  • Beginning in the 1880s several experiments were performed to try to detect this motion, the most famous of which is the experiment performed by Albert A. Michelson and Edward W. Morley in 1887.[128] The detected motion was always less than the observational error. Modern experiments indicate that the two-way speed of light is isotropic (the same in every direction) to within 6 nanometres per second.[129]
  • ...1 more annotation...
  • In 1972, using the laser interferometer method and the new definitions, a group at NBS in Boulder, Colorado determined the speed of light in vacuum to be c = 299792456.2±1.1 m/s. This was 100 times less uncertain than the previously accepted value. The remaining uncertainty was mainly related to the definition of the metre.[Note 8][104] As similar experiments found comparable results for c, the 15th Conférence Générale des Poids et Mesures (CGPM) in 1975 recommended using the value 299792458 m/s for the speed of light.[136]

  • Soon the robots learned to follow the signals of others who’d gathered at the food. But there wasn’t enough space for all of them to feed, and the robots bumped and jostled for position. As before, only a few made it through the bottleneck of selection. And before long, they’d evolved to mute their signals, thus concealing their location.
  • “Evolutionary robotic systems implicitly encompass many behavioral components … thus allowing for an unbiased investigation of the factors driving signal evolution,” the researchers wrote Monday in the Proceedings of the National Academy of Sciences. “The great degree of realism provided by evolutionary robotic systems thus provides a powerful tool for studies that cannot readily be performed with real organisms.”

Human Trafficking in East Asia | Foreign Policy Journal - 0 views

  • Interestingly, reports estimate that 30% to 40% of this is unregulated traffic. It is unclear how much of this migration flow is human trafficking, but it is clear that at the very least, a significant portion of it is.
  • An amplification in the demand for domestic servants in developed countries combined with unemployment of women in developing countries has seen the growth of entire organized crime gangs devoted to fulfilling this need, albeit illegally.
  • according to the United Nations Office of Drugs and Crime (UNODC), sexual exploitation is the “most commonly-identified form of human trafficking.”

  • Consider the one-child policy in China that has lead to a skewed gender ratio. Because of this, brides are ‘sold’ for a premium across China.
  • Trafficking plays a cyclical role with organized crime, and we must strike at both to render the world safe.

China and Nigeria: Neo-Colonialism, South-South Solidarity, or Both? | Daniel Wagner - 0 views

  • Bilateral relations between China and Nigeria will likely take one of two paths in the long term: either China will remain the overwhelmingly dominant actor or Nigeria will become a regional superpower, evening out the playing field. If China remains the stronger player it will shape Nigeria in its own interests (commonly referred to as "Chinese Imperialism").
  • During the first eleven years of its independence, Nigeria and China had no diplomatic relations. The Nigerian government's view of China grew especially sour after Mao officially supported the secessionist state in Biafra by supplying the Biafran administration with weapons.
  • During the period of General Abacha's military rule (1993-1998), Beijing's no-strings-attached development projects were increasingly well received. Nigeria's leaders grew resentful of Western conditions for aid and investment, and many Nigerians began to question what a generation of economic dependence on the West achieved for Nigeria.

  • Abuja subsequently adopted a new approach to international trade, balancing traditional Western partners and China.
  • The evolution of Nigerian-Chinese relations mirrors that of China's relationship with other African states (such as Angola, Sudan, and Zimbabwe) that sought alternative forms of aid and development packages following the imposition of sanctions by Western nations based on alleged human rights violations.
  • Today, more than 200 Chinese firms operate in Nigeria.
  • China agreed to provide Nigeria with a soft loan of $1.1 billion loan in exchange for Nigeria agreeing to increase its daily supply of oil to China ten-fold (from 20,000 barrels per day to 200,000) by 2015.
  • China recently embraced a new foreign policy in West Africa that contrasts with its traditionally passive approach to the spread of Islamic terrorism and extremism in Africa. Last year a Chinese diplomat in Mali pledged support for the Economic Community of West African States (ECOWAS)'s military campaign to dislodge Al Qaeda-affiliate groups in northern Mali.
  • China's number one concern in West Africa is access to natural resources and new consumer markets
  • While many Nigerians consider China's growing presence to be nothing short of a God send, others have raised concerns about Nigerian sovereignty, bearing in mind the impact Chinese trade and investment has had on other African countries.
  • The Chinese model of importing its own workers to build infrastructure projects, for example, does not sit well with many Nigerians.
  • A number of Nigerians have also voiced objections to the "slave-like" labor conditions in Chinese-operated factories across Nigeria. Attention was first brought to these conditions when 37 Nigerian workers died after being trapped inside a locked Chinese-owned factory that caught fire in 2002
  • Western powers that claim a desire to help Nigeria develop are often perceived as insincere, with their own aid being viewed as an infringement on Nigeria's sovereignty, since it often comes with strings attached.

Recognising the proteins that indicate cancer : News : News + Events : National Physica... - 0 views

  • All diseases have proteins, or concentrations of proteins, specifically linked to them called biomarkers, and identifying these can prove a powerful diagnostic tool. Antibodies can be used to test for specific biomarkers because they only bind to specific molecules or groups of molecules. Problems can arise when they bind to groups of similar molecules, leading to false positives and unreliable information.

USATODAY.com - Do thin models warp girls' body image? - 0 views

  • "We have done studies of grade-school girls, and even in grade 1, girls think the culture is telling them that they should model themselves after celebrities who are svelte, beautiful and sexy."
    • braxtondn
       
      Being sexy doesn't mean you have to be skinny. As long as the skin you're in makes you feel sexy and beautiful thats all that should matter. People don't need advice from a celebrity, who also struggled with their body image, to tell them that in order to be considered sexy by the media and today's society, you have to be skinny.
  • Some girls can reject that image, but it's a small percentage: 18% in Murnen's research
    • braxtondn
       
      That is a shame that only 18% are unaffected by media's new idea of an acceptable look. They must either have a high self-esteem or do not interact with the media as much as the other 82%.
  • those who were exposed to the most fashion magazines were more likely to suffer from poor body images.

      This shows that magazines such as Seventeen and Vogue are held responsible for the negative image that they are putting into teens' mind. They do not need to be skinny enough to put on a magazine cover, they need to accept the skin they are in and show it.

  • t's not surprising that women want to be slender and beautiful, because as a society "we know more about women who look good than we know about women who do good," says Audrey Brashich, a former teen model and author of All Made Up: A Girl's Guide to Seeing Through Celebrity Hype and Celebrating Real Beauty.

      Hearing this from a teen model who was probably in the 18% of young women who weren't effected by the media, is amazing because she knows what is most important. Although looks play a major part in being successful, the hard work is more important. Media is taking away the important concept and forcing a lesser concept to become the main focus.
