In the first weeks of 1980, Public Broadcasting Service affiliates across the United States aired Free to Choose, a television series featuring the economist Milton Friedman. This article focuses on the production team, which brought Friedman’s small-government, market-focused perspective via privatizing the production of public television. Specifically, executive producer Robert Chitester’s success in bringing the series to air stemmed from two factors: first, he expressed social imaginaries that helped coordinate funding relationships with underwriters; and second, he drew on his institutional knowledge of public television production to navigate zones of regulatory ambiguity without running afoul of broadcast rules and regulations.  相似文献

An implicit assumption that fostering inclusion means having shared systems encompassing the needs of all children is evident in many aspects of policy development over the past decade. Reflecting this, the implementation of ‘baseline assessment’ schemes (i.e. testing at around age 5 years) is a statutory requirement on all state-maintained special and mainstream schools in England since 1998. Our argument is that the enthusiasm for commonality has obscured the need to question the value and validity of baseline assessment schemes for children with special educational needs (and possibly some others such as children having English as an additional language). We illustrate this position with reference to data from our recent study on baseline assessment in England. The study encompassed survey data from a national sample of 982 schools, of which 107 were special schools. Between them, these special schools used 42 different baseline assessment schemes. Comparisons between our mainstream and special school respondents indicated that there were similarities in the nature and perceived value of the schemes used. However, special schools were less satisfied with their schemes. We suggest that a reappraisal of the nature and purpose of baseline assessment for pupils with special educational needs warrants greater critical debate. Without this, there is a danger that a stress on commonality, veiling an inclusion orthodoxy, will ultimately be counterproductive.  相似文献

Though there is a long tradition of band members quitting the group or taking a hiatus, the rock group as an organization to produce music continues to be both popular and economically viable. The research question addressed in this paper is whether or not it is a good idea to quit or take a hiatus from the group. We begin with a discussion of the framework for understanding why groups are formed and why they may be difficult to keep together. We then discuss differences between groups in the decade of the 1960s versus today. We argue that there is something unique about the output of the group even with the changes in the structure of contracts, compensation, and consumer focus on the artist that explain the resilience of the rock band as an organizational form within which to create music. We compare the charting success of bands that have members leave the group with the charting success of the members who left the group. We identified the groups in five representative years: 1965, 1975, 1985, 1995, and 2005. We then analyzed the entire Billboard Hot 100 charting careers of those groups and the artists who quit those groups. Our main finding is that when charting success is divided equally among members, going solo pays off—there is a clear economic rationale because solo acts have greater average charting success than the original bands they started in. The other ensuing side projects: duos, collaborations, and other groups are not as lucrative as the original bands. These findings are valid for members of charting groups from each of the 5 years examined. Despite the difficulties in keeping a rock band together, there are fewer band breakups today and remaining with the group generally results in a longer and more productive charting career. Thus, the rock group remains an important organization for producing contemporary music. However, there remains a compelling incentive to go solo. Superstars may benefit from solo projects, but for the average, non-superstar group member, in many circumstances it is better for the band to stay together if the income is divided equally.  相似文献

ABSTRACT

This study aimed to translate movement patterns, technical skills and tactical actions associated with high-intensity efforts into metrics that could potentially be used to construct position-specific conditioning drills. A total of 20 individual English Premier League players’ high-intensity running profiles were observed multiple times (= 100) using a computerised tracking system. Data were analysed using a novel high-intensity movement programme across five positions (centre back [CB], full-back [FB], central midfielder [CM], wide midfielder [WM] and centre forward [CF]). High-intensity efforts in contact with the ball and the average speed of efforts were greater in WMs than CBs, CMs and CFs (effect sizes [ES]: 0.9–2.1, < 0.05). WMs produced more repeated efforts than CBs and CMs (ES: 0.6–1.3, < 0.05). In possession, WMs executed more tricks post effort than CBs and CMs (ES: 1.2–1.3, < 0.01). FBs and WMs performed more crosses post effort than other positions (ES: 1.1–2.0, < 0.01). Out of possession, CFs completed more efforts closing down the opposition (ES: 1.4–5.0, < 0.01) but less tracking opposition runners than other positions (ES: 1.5–1.8, < 0.01). CFs performed more arc runs before efforts compared to CBs, FBs and WMs (ES: 0.9–1.4, < 0.05), however, CBs completed more 0–90° turns compared to FBs, CMs and WMs (ES: 0.9–1.1, < 0.01). The data demonstrate unique high-intensity trends in and out of possession that could assist practitioners when devising position-specific drills.  相似文献

The purpose of this study was to investigate whether a linear factor analytic method commonly used to investigate violation of the item response theory (IRT) unidimensionality assumption is sensitive to measurable curricular differences within a school district and to examine the possibility of differential item performance for groups of students receiving different instruction. For grades 3 and 6 in reading and mathematics, personnel from two midwestern school systems that regularly administer standardized achievement tests identified the formal textbook series used and provided ratings of test-instructional match for each school building (classroom). For both districts, the factor analysis results suggested no differences in percentages of variance for large first factors and relatively small second factors across ratings or series groups. The IRT analyses indicated little, if any, differential item performance for curricular subgroups. Thus, the impact of factors that might be related to curricular differences was judged to be minor.  相似文献

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children.  相似文献
