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. 相似文献

The study investigated how well report card grades communicate to students and parents that state educational standards are
being met, standards that are objectively measured by infrequently administered mandated assessments. Data sources were report
card grades and external assessment scores for 2006–09 for Ontario Canada. The information that parents and students received
about student performance from report cards and external assessments were similar (r
s
= .47) to the r = .40–.60 range previously reported. Teachers assigned higher grades than external assessments warranted, even after a major
source of construct irrelevant variance in report card grades (teacher ratings on multiple scales measuring student effort
and school commitment) was controlled. The relationship of grades to assessment scores was robust across genders, school district
types (Public versus Catholic) and language (English and French). Agreement of assessments was higher for grade 6 than for
grade 3 and for Writing than for Reading or Mathematics. Report cards provided information about students’ future achievement
that was accurate and delivered up to 2 years prior to the administration of external assessments. Seventy to 80% of students
who reached the provincial achievement standard on one or both prior report cards were successful on the subsequent external
assessment, compared to 30–50% of students who failed to meet the report card standard at least once. 相似文献

Eccentric contractions that provide spring energy can also cause muscle damage. The aim of this study was to explore leg and vertical stiffness following muscle damage induced by an eccentric exercise protocol. Twenty active males completed 60 minutes of backward-walking on a treadmill at 0.67 m/s and a gradient of ? 8.5° to induce muscle damage. Tests were performed immediately before; immediately post; and 24, 48, and 168 hours post eccentric exercise. Tests included running at 3.35 m/s and hopping at 2.2 Hz using single- and double-legged actions. Leg and vertical stiffness were measured from kinetic and kinematic data, and electromyography (EMG) of five muscles of the preferred limb were recorded during hopping. Increases in pain scores (over 37%) occurred post-exercise and 24 and 48 hours later (p < 0.001). A 7% decrease in maximal voluntary contraction occurred immediately post-exercise (p = 0.019). Changes in knee kinematics during single-legged hopping were observed 168 hours post (p < 0.05). No significant changes were observed in EMG, creatine kinase activity, leg, or vertical stiffness. Results indicate that knee mechanics may be altered to maintain consistent levels of leg and vertical stiffness when eccentric exercise-induced muscle damage is present in the lower legs. 相似文献

This book review essay discusses and analyzes how introductory textbooks on correctional administration, written primarily for the American university market, frame the discourse on this subject matter. The writer presents both quantitative and qualitative empirical evidence of coverage given to prison administration. In addition to traditional content analysis methods, the authors of these books were contacted and asked to explain the decision‐making processes they used for content inclusion, exclusion and/or minimization. The paper concludes with a handful of recommendations on improving texts in this subdiscipline. 相似文献

This article examines how career portfolio programs at two secondary schools establish corporeal regimes. Both programs require students to compose portfolios that plot their trajectories through school and into paid work. Prior to graduation, students defend their portfolios before panels of educators and businesspeople. Employing the Bourdieusian concepts of capital and habitus, this article investigates how these programs set up systems that value certain kinds of bodies. Further, it examines how students negotiate these systems and display different kinds of bodies in different kinds of ways. Ultimately, it is argued these disparate bodily performances are read by authorities as indicators of the types of paths students are travelling or should travel into the future. 相似文献
