This article explores the British and West German public service radio’s abilities to reflect on and to address the specific needs and expectations of migrant groups in their programmes between the 1960s and 1980s. Mechanisms of social inclusion and exclusion alike can be investigated here. Empirically, it is based on comparisons of radio broadcasts on and for different immigrant communities, produced by BBC Radio Leicester on/for the post-war Asian migrants in England and by West German public service broadcasting on/for ‘Gastarbeiter’ (foreign workers) as well as for ‘Spätaussiedler’ (German repatriates from East Europe). Radio is studied as an agent of identity management and citizenship education. Not only did radio talk about migrants and migration to introduce these topics and the newcomers to the local population. It also offered airtime to selected migrant communities to cater for their needs and interests as well as to facilitate their difficulties of adjusting to an unfamiliar environment. 相似文献

This article elaborates on media-induced nostalgia as a mixed emotion elicited by remembering past media content and characters. It argues that social components of media consumption such as parasocial relationships (PSRs) play an important part in the elicitation of nostalgia. In an online study, participants (N = 96) remembered their individual media use and preferred media characters as children. Results show that media-induced nostalgia is significantly associated with PSRs to characters in the past. These findings are evaluated concerning their implications for future research on nostalgia and PSRs. 相似文献

For sports actors, social media provide the opportunity to bypass sports journalism's gatekeeping function and to disseminate sports-related information to target groups directly. Thus, social media have been conceptualized as a competitor to journalism. We argue that the relation is much more diverse. We differentiate between competitive, integrative, and complementary facets of the relationship between sports journalism and social media. Our study focuses on complementarity and analyzes how far social and mainstream media serve as sources for each other. Therefore, we combine an online survey among 122 German sports journalists, an analysis of the Twitter networks of German sports journalists during the Winter Olympics 2014, and a content analysis of the most popular news items in social media. Results suggest that sports journalists perceive social media accounts of athletes as beneficial news sources, especially to gather inside information. Huge sports events influence the social media activities of sports journalists as they tend to have stronger connections to athletes at these times. Whereas social media appear to be significant sources for sports journalism, sports media content receives little attention in social media. However, our results indicate that sports journalism and social media indeed maintain a complementary relation. 相似文献

Low energy availability, defined as low caloric intake relative to exercise energy expenditure, has been linked to endocrine alterations frequently observed in chronically energy-deficient exercising women. Our goal was to determine the endocrine effects of low energy availability in exercising men. Six exercising men (VO2peak: 49.3 ± 2.4 ml · kg?1 · min?1) underwent two conditions of low energy availability (15 kcal · kg?1 fat-free mass [FFM] · day?1) and two energy-balanced conditions (40 kcal · kg?1 FFM · day?1) in randomised order. During one low energy availability and one balanced condition, participants exercised to expend 15 kcal · kg?1 FFM · day?1; no exercise was conducted during the other two conditions. Metabolic hormones were assessed before and after each 4-day period. Following both low energy availability conditions, leptin (?53% to ?56%) and insulin (?34% to ?38%) were reduced (P < 0.05). Reductions in leptin and insulin were independent of whether low energy availability was attained with or without exercise (P > 0.80). Low energy availability did not significantly impact ghrelin, triiodothyronine, testosterone and IGF-1 (all P > 0.05). The observed reductions in leptin and insulin were in the same magnitude as changes previously reported in sedentary women. Further research is needed to understand why other metabolic hormones are more robust against low energy availability in exercising men than those in sedentary and exercising women. 相似文献

Recent research on metacognition points out the crucial role of on-line methods when endeavouring to conduct valid assessments
of metacognitive skills. Presently, different on-line methods are used, however, it is still a question of research whether
and how they affect students’ learning behaviour and learning outcome. Thus, the aim of this study is to quasi-experimentally
analyse the effects of two on-line verbalisation methods on learning performance. By means of the thinking-aloud method, students
in one experimental group (n = 24) were instructed to read and think aloud during learning. With the reflection when prompted method, students of another
experimental group (n = 24) were prompted at each navigational step to reflect on the reasons why they chose specific information. Students in
the control group (n = 22) learned without being instructed to verbalise. All three groups were treated identically except for the different use
of verbalisation assessment methods. The students’ task was to learn the concepts and principles of operant conditioning presented
in a hypermedium within 30 min. The students’ learning sessions were videotaped and learning performance was obtained immediately
afterwards. Based on Ericsson and Simon’s (Protocol analysis: Verbal reports as data, MIT, Cambridge, 1993) model, no performance differences between the thinking aloud and the control group were hypothesised.
However, prompting students for metacognitive reflection should affect learning performance positively, which is confirmed
by the results only in tendency for transfer performance. Implications for on-line assessment methods of metacognitive skill
will be discussed. 相似文献

This study analyses the use of a group space on the social networking site Facebook as a way to facilitate research supervision for teams of learners. Borrowing Lee’s framework for research supervision, the goal was to understand how supervision and learning was achieved in, and shaped by, the properties of a social networking space. For this purpose, the discourse between supervisor and learners was analysed along with the structural properties afforded by the space. Using the empirical findings and further literature, a conceptual framework was developed that illustrates the ways in which functional supervision, enculturation, emancipation, critical thinking and relationship development are achieved and formed by the interplay of the technological, functional, multimodal and the wider sociocultural, political and sociolinguistic structures associated with social media space. 相似文献
