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   

Within‐High‐School Versus Across‐High‐School Scaling of Admissions Assessments: Implications for Validity and Diversity Effects          下载免费PDF全文

Jack W. Kostal  Paul R. Sackett  Nathan R. Kuncel  Philip T. Walmsley  Melissa S. Stemig 《Educational Measurement》2017,36(1):39-46

Previous research has established that SAT scores and high school grade point average (HSGPA) differ in their predictive power and in the size of mean differences across racial/ethnic groups. However, the SAT is scaled nationally across all test takers while HSGPA is scaled locally within a school. In this study, the researchers propose that this difference in how SAT scores and HSGPA are scaled partially explains differences in validity and subgroup differences. Using a large data set consisting of 170,390 students each of whom matriculated at one of 114 separate colleges, the researchers find that awarding SAT scores by ranking SAT within a high school generally results in substantial reduction in the size of subgroup mean differences for this predictor. However, validity for predicting first‐year GPA is also reduced by a small amount. Conversely, placing HSGPA onto a nationally normed metric through the use of multiple regression procedures results in a moderate increase in the size of subgroup mean differences, while also producing a small increase in validity. Taken together, these findings suggest that differences in predictor scaling can partially explain differences in the size of subgroup mean differences between HSGPA and SAT scores and have implications for predictive power.  相似文献   

Social reproduction and education policy     

Jack Demaine 《International Studies in Sociology of Education》2013,23(2):125-140

The last half-century of sociology of education is littered with the debris of functionalist theories about social reproduction, inequality and class. This article discusses 'progressive 'and 'conservative 'readings of arguments about social reproduction and explores the consequences for the sociology and the politics of education with reference to supposed 'influence ' and 'audience'. New Labour's embrace of the school effectiveness/improvement movement and the introduction of the Sure Start programme illustrate that while 'social reproduction' is still a concern for sociologists of education, policy-makers have more 'practical' concerns.  相似文献
