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

Sexual Health Equity in Schools: Inclusive Sexuality and Relationship Education for Gender and Sexual Minority Students     

Emily Meadows 《American journal of sexuality education》2018,13(3):297-309

ABSTRACT

This paper offers a review of school-based sexuality and relationship education as it relates to gender and sexual minority (GSM) students. Framed by a queer theory lens, the paper examines four main topics: (a) sexual health and relationship risks for GSM youth, (b) comprehensive school-based sexuality education as a protective factor for sexual health and relationship risks, (c) the current availability of relevant sexuality education for GSM students in the United States, and (d) inclusive schools as a social determinant of health. The author advocates for health equity, and offers suggestions for inclusive, comprehensive sexuality and relationship education to provide relevant, accurate, positive information for all students.  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   

Experientially learning how to communicate science effectively: A case study on decoding science     

Monique L. R. Luisi  Shelly Rodgers  Jack C. Schultz 《科学教学研究杂志》2019,56(8):1135-1152

The need for science communication programs is matched with the need for program evaluation. This case study is an evaluation of the “Decoding Science” program (DSP) [Rodgers et al. (2018). Science Communication, 40(1), 3–32], a science communication training program, and examines key experiential-learning themes [Kolb, D. A. (1984). Experiential learning: Experience as the source of learning and development. Englewood Cliffs, NJ: Prentice-Hall]. Specifically, we discuss the program's emphasis on learning that science communication is a process that (a) is continual, (b) involves conflict resolution, (c) requires adaptation to the world, (d) requires environmental interaction, and leads to (e) knowledge creation. Additionally, we discuss our analysis of student feedback. Results suggest that the DSP successfully utilizes experiential learning to facilitate the learning of science communication techniques and that future evaluations can lead to the development and improvement of science communication training programs.  相似文献   

Concurrent validity of the Woodcock-Johnson tests of cognitive ability with the WISC-R: EMR children     

Jack A. Cummings  David Sanville 《Psychology in the schools》1983,20(3):298-303

The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) were administered in a counterbalanced order to 30 children referred for a three-year reevaluation. All children were currently placed in an educable mentally retarded (EMR) program. The children ranged in age from 8-0 to 12-5 years, with a mean of 10-6. The correlation coefficient between the WISC-R and WJTCA was observed to be .72. Significant mean differences were found between the WISC-R and WJTCA full scale standard scores. The implications of the findings are discussed relative to the placement of children in classes for the mentally retarded. Explanations for the mean differences between the WJTCA and WISC-R also are explored.  相似文献   

Teacher pupil control ideology and pupils' projected feelings toward teachers     

Frederick C. Lunenburg  Jack W. Stouten 《Psychology in the schools》1983,20(4):528-533

The relationship between teacher pupil control ideology and pupils' projected feelings toward teachers was examined. The Pupil Control Ideology Form, based on a custodial-humanistic continuum, served as the operational definition for teacher views toward pupil control. Lemeshnik's Draw-A-Teacher technique, a projective device based on a negative-positive continuum, served as the operational definition of pupils' projected feelings toward teachers. A sample of 131 teachers and their students responded to these instruments, respectively. Pearson product-moment correlations indicated that custodialism in teacher pupil control ideology was directly related to pupils' negative feelings toward teachers. Multiple regression analysis indicated that pupil control ideology, followed by teacher sex and grade level, predicted pupils' feelings toward teachers. Further analysis revealed that boys projected more negative feelings toward teachers than did girls.  相似文献
