The effect of television viewing on ethnic prejudice against immigrants: A study in the Italian context     

《Int J Intercult Relat》2015

Television viewers construct many different meanings from the programs they watch. Here, we investigated whether ethnic prejudice is differentially influenced by the genre of television programs in their portrayal of ethnic minorities. We also wanted to determine whether a higher educational level reduces ethnic prejudice and television use. A self-reported questionnaire was administered to 401 Italian adults. Structural equation modeling was used to analyze the relationships between ethnic prejudice and television program contents and educational level. Viewing Reality and Variety Shows was positively related to ethnic prejudice, News and Public Affairs was negatively related, and Films and TV series had no apparent influence on prejudice. Educational level was negatively related to both ethnic prejudice and watching Reality and Variety Shows, and positively related to viewing News and Public Affairs and Films and TV series programs.  相似文献   

Timescales for exploratory tactical behaviour in football small-sided games

The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games.  相似文献

大学适度规檩的取值条件分析     

刘志民 《黑龙江高教研究》2004,(11):6-9

规模经济理论被应用于大学适度规模研究，是基于大学资源优化配置后能产生规模效益的认识，已经采用的研究方法主要有：统计成本分析法、适生存检验法和MR与MC分析法。规模经济理论及研究方法的局限性及高等教育的特殊性，使得大学最小有效规模或最佳规模的研究结果有很大差异。因此，大学在选择适度规模时应综合考虑基本办学条件、学校发展定位、教育市场需求等约束条件，根据自身资源利用与再生潜力确立一个相对合理的规模区间。  相似文献   

Being and becoming a university teacher     

Wendy McMillan 《高等教育研究与发展》2017,36(4):777-790

This study examined how one academic framed the enablements and constraints to her project of being and becoming an academic. Complexity facilitated reflection in that it provided a visual representation of data, which was used to generate a concept map, which represented as equal all the component parts of her landscape. Five spaces with emancipatory potential to assist the academic in her professional development emerged, namely: communities of practice, academic freedom, position statements, development opportunities and a supportive environment. Rather than suggesting any generalisability in the findings, the authors argue that the significance of this study is theoretical and methodological. Complexity theory has the potential to help academic development practitioners understand the landscapes in which their academics operate, and guide appropriate development opportunities.  相似文献
