VALUE-FRAMING ABORTION IN THE UNITED STATES: AN APPLICATION OF MEDIA SYSTEM DEPENDENCY THEORY

This paper is in the tradition of social analysis aimed at creatingframeworks to join mass media and public opinion processes (e.g.Clarke and Evans, 1983; Gamson, 1975; Gitlin, 1980; Hall, 1977;Iyengar and Kinder, 1987; Lang and Lang, 1968, 1983; Lippman,1922; Mollotch and Lester, 1974; Noelle-Neuman, 1974; Paletzand Entman, 1981; Shaw and McCombs, 1977; Turner and Paz, 1986).After a brief review of media system dependency (MSD) theory,we illustrate how it may apply to public opinion processes thatentail contested issue ‘value-frames’ (Ball-Rokeachand Rokeach, 1987). In such cases, the media system is directlyimplicated in the negotiation of legitimacy of opposing positionson an issue. Our illustrative case is the abortion issue asit has been played out in the United States over recent decades(Luker, 1984). We focus upon the respective capacities of pro-and anti-abortion movements to control the value-frame of mediacoverage of the issue (Guthrie, 1989). A value-frame may beconceived as ‘... the main substantive theme of a moralityplay’ (Ball-Rokeach and Tallman, 1979) wherein the distinctionbetween ‘good’ and ‘bad’ hangs in thebalance; in this case, between positions on abortion. We suggestthat change in the value-frame of media coverage and publicdiscourse may be understood, at least in part, as an outcomeof change in contestants' MSD relations.     

Social Welfare,the Neo‐conservative Turn and Educational Opportunity

This essay examines the educational opportunities of people in poverty who receive social welfare assistance. The dominant political theory underlying social policy (including education policy) in the United States has evolved from 1960s and 1970s welfare liberalism into 1980s and 1990s style neo‐conservatism—a theory that embraces principles of the market and individual liberty as paramount social values. Against this backdrop, I review two recent books that provide compelling evidence for this turn and I call for increased understanding of the relationship between social welfare policies and higher education opportunities for those in poverty.     

群众自我健身意识的现状与对策

2001~2010年是《全民健身计划纲要》实施第二期工程的时期,本时期的目标是:经过十年的努力,把全民健身工作提高到一个新的水平,基本建成具有中国特色的全民健身体系。然而在纲要的实施过程中,发现群众的自我健身意识不强,存在赌博、迷信、懒惰的现象,败坏家庭和社会的风气。特别是近年来因体育活动不足而引起“亚健康”人员的增多,重新提出“全民健身计划”尤为必要。
