Producing Milton Friedman’s Free to Choose: How Libertarian Ideology Became Broadcasting Balance     

Caroline Jack 《广播与电子媒介杂志》2018,62(3):514-530

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   

High-intensity efforts in elite soccer matches and associated movement patterns,technical skills and tactical actions. Information for position-specific training drills     

Jack Ade  John Fitzpatrick 《Journal of sports sciences》2016,34(24):2205-2214

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 (n = 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, P < 0.05). WMs produced more repeated efforts than CBs and CMs (ES: 0.6–1.3, P < 0.05). In possession, WMs executed more tricks post effort than CBs and CMs (ES: 1.2–1.3, P < 0.01). FBs and WMs performed more crosses post effort than other positions (ES: 1.1–2.0, P < 0.01). Out of possession, CFs completed more efforts closing down the opposition (ES: 1.4–5.0, P < 0.01) but less tracking opposition runners than other positions (ES: 1.5–1.8, P < 0.01). CFs performed more arc runs before efforts compared to CBs, FBs and WMs (ES: 0.9–1.4, P < 0.05), however, CBs completed more 0–90° turns compared to FBs, CMs and WMs (ES: 0.9–1.1, P < 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   

Knowledge acquisition by computerized audiovisual feedback     

Fischer  Peter Michael  Mandl  Heinz 《European Journal of Psychology of Education - EJPE》1988,3(2):217-233

The present article gives an outline of the state of art in computer assisted intervention by learning-concomitant differential feedback. Based on the spectrum of possible meanings and interpretations given to the concepts ‘interaction’ and ‘interactive’ this concept is elaborated and illustrated by prototypical theoretical approaches. Based on our own empirical findings arguments are given showing that sophisticated audiovisual interactive new technologies can properly be used even on the small machines available in schools if the content materials and the flow of control given to the learner are carefully designed and based on principles of cognitive science.

Policy change in Austrian higher education: indications of a new approach     

Karl Heinz Gruber 《Higher Education》1991,21(4):607-619

Despite significant expansion in participation over the last three decades, Austrian higher education has been slow to change either its elitist self-concept or structure. But, as is the case elsewhere, the Austrian academic community is beginning to be confronted with such concepts as efficiency, strategic planning, deregulation, and performance evaluation. Inadequate admission policies, extreme overcrowding, and high dropout rates are but three factors placing pressure on Austrian higher education to reform. The system is not only in need of increased budget allocations, but also requires new policies to guide it into the 21st Century.  相似文献   

US inflation with trace and simultaneous fear conditioning     

Jack Edward Sherman 《Learning & behavior》1978,6(4):463-468

Two experiments with rat subjects in a conditioned punishment paradigm are reported. These experiments attempted to determine if the events entering into association with the CS following conditioning with informative (forward) and noninformative (simultaneous) CSs were comparable. In Experiment 1, exposure to intense shock alone following trace (ISI = 10 sec) conditioning with moderate shock enhanced the suppressive effects of a 2-sec CS. A similar manipulation following explicitly unpaired CS-US presentations (ISI = 2 min) had no effect. These data were taken as evidence that the CS and US were associated during trace conditioning. Experiment 2 showed that exposure to intense shock following simultaneous conditioning also enhanced suppression to the CS. These results suggested that simultaneous and forward conditioning procedures yield similar forms of associative learning.  相似文献   

Racism,Ideology and Education: the last word on the Honeyford affair?     

Jack Demaine 《British Journal of Sociology of Education》1993,14(4):409-414

The paper begins with a brief reference of some of the inaccuracies in accounts of the so called ‘Honeyford affair’. The main purpose of the paper, however, is not to compare differing accounts, but rather to examine aspects of Honejford's discourse in its own terms. These aspects include his notion of ‘racism’, his concern with ‘tolerance and coherence’ and his account of what he refers to as ‘the human character’.  相似文献   

PASS cognitive processes,phonological processes,and basic reading performance for a sample of referred primary‐grade children     

Laurice M. Joseph  Megan E. McCachran  Jack A. Naglieri 《Journal of Research in Reading》2003,26(3):304-314

The purpose of this study was to explore the relationships among cognitive processing, phonological processing and basic reading skill performance. Cognitive theorists propose that Planning, Attention, Simultaneous and Successive (PASS) processes are related to various phonological skills. A sample of 62 Primary Grade children referred for reading problems were administered measures of cognitive processes (Cognitive Assessment System), phonological processes (Comprehensive Test of Phonological Processing) and basic reading achievement (Woodcock‐Johnson Tests of Academic Achievement‐III). Findings indicated that some cognitive processes were significantly related to phonological processes as well as basic reading skills. The strongest relationships were found between phonological memory and successive processes and between phonological awareness and basic reading performance.  相似文献   

教育中的新制度主义     

海因兹-迪特·迈尔  布莱恩·罗万  郑砚秋 《北京大学教育评论》2007,5(1):15-24

制度理论一直将教育领域作为一个重要的研究对象。近十几年来,在教育领域出现了三个显著的变化,它们分别是教育服务提供从单一走向多元、教育系统结构从松散变为紧密以及教育制度重要性的增加。这些教育制度变化的新对于以往制度理论的基本命题提出了挑战,要求重新审视一些制度关系,如同形性与多样性、合法性与效率、松散性与紧密性、制度约束与制度创新、政府与市场等。这预示着对于教育领域进行制度研究的广阔前景。  相似文献
