英国公共服务广播面临的问题及对策

公共服务广播(Public Service Broadcasting,在本文中主要指电视广播)在英国的历史由来已久,公营的立法体制保证了节目较为丰厚的资金来源,也催生了高品质的节目内容.英国公共广播电视机构出品的节目通常是由本国制作的原创性作品,内容精良,创意新颖,很少是来自国外的舶来品.为了保证公共广播电视节目的公众服务性,英国广播电视和通信的最高管理机构--通信办公室(the Office of Communications,Ofcom)还会定期对公共广播电视机构进行评估,考察它们是否达到了公共服务广播的目标,并对之如何保持和加强公共广播的高品质服务提出建议.

The powerful image and the imagination of power: the ‘new visual turn’ of the CPC’s propaganda strategy since its 18th National Congress in 2012

This paper adopts the academic tool of discourse analysis to examine the ‘new visual turn’ of the Communist Party of China’s propaganda work since the 18th CPC National Congress when Xi Jinping was inaugurated as the leader of Chinese Communists. A thorough review of the new visual means the Party uses for photojournalism, TV news, animated cartoons and online promotional videos points to three developments markedly different from traditional discursive strategies: a full embrace of Confucian ethics, articulation of the Internet-based popular culture and subcultures, and an effort to fortify Xi’s personal authority as a political idol. The paper concludes that the ‘new visual turn’ of CPC propaganda after the 18th Party Congress suggests that the Communist discourse has evolved to a new stage where sophisticated manipulation of sleek technological tools substantiates a rigorous, dynamic CPC discursive system more at ease with itself and more powerful than ever in shaping the mainstream political culture in China.     

The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.     

Cross-Cultural Adaptation and Psychometric Properties of the Portuguese Version of the Life Skills Scale for Sport

ABSTRACT

This research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants.
