Using football cultures as a vehicle to improve mental health in men: the case of the Redcar and cleveland boot room

This paper sets out to appraise (from the perspective of members) the impact of a localized, football-based mental health intervention. Commissioned in late 2015, the ‘Redcar and Cleveland Boot Room (BR)’ was implemented in response to mass redundancy in the local area, coupled with regional suicide rates in men that exceed the national average. Interactive discussions with BR members revealed that: (a) the language of football and shared identity were important for initiating and sustaining engagement in the BR; (b) peer-support and mentoring combined with member-led activities were active ingredients of the BR and (c) that the BR was an effective vehicle for building mental health resilience. This evaluation adds to the evidence base on the value of football as a context to engage adult males in community-based interventions targeting mental health resilience.     

‘Who is zooming who’? A study of young PE-students in their figurations

The article presents an analysis of 93 essays written in an upper secondary school context. The essays were collected in relation to a larger research project, which went on for 5 years in a Danish upper secondary school (2010–2015). The material represents both genders and the students are 15–17 years old. We deploy a theoretical framework taken from Norbert Elias’ notion on established-outsider relations [Elias, N., &; Scotson, J. L. (1994 [1965]). The established and the outsiders. London: SAGE] as well as his use of personal pronouns [Elias, N. (1978). What is sociology? London: Hutchinson, Elias, N. (2001). The society of individuals. New York: The Continuum International Publishing Group] in illustrating how people negotiate, position and navigate within figurational contexts [Elias, N. (1994 [1939]). The civilizing proces. Oxford: Blackwell.]. We do this in an effort to interpret how young people negotiate ‘we-I-relations’ when it comes to their sporting identity. Elias’ processual framework provides a tool for a much needed analysis of how young people continually orientate and develop their sense of selves. The web of human interdependencies and processes of change are key words when it comes to understanding the social practices and doings of the students’ constructions of self-steering. What social scientists may see as laziness and drop-outs of sports [Seippel, Ø. (2016). Prek, vekker og kjedelig? Trening og mening blant ungdom: 1985–2013. In Ø. Seippel, M. K. Sisjord, &; Å Strandbu (Eds.), Ungdom og Idrett. Oslo: Cappelen Damm Akademisk] can in the essays of students be analysed as a struggle for group connectedness and social inclusion in the classroom. The results of our research show that identity is a multiple concept and an ongoing process of emotional work [Elias, N. (1987). On human beings and their emotions: A process-sociological essay. Theory Culture Society, 4, 339–361], but also a power balance of playing and presenting what is imagined as the right performance as not being shamed as outcasts.     

Heritage sporting events: theoretical development and configurations

ABSTRACT

Although sports heritage is increasingly recognized as a potential catalyst of tourism, heritage sporting events (HSEs) are still an emerging concept in the academic literature. Notions that associate sports events and heritage remain rare, and are usually analysed through the scope of nostalgia sport tourism. This can be partly explained by an inclination to associate the notion of heritage with conventional ideas about folklore and traditional culture. Through a constructivist approach of heritage, this contribution argues that contemporary sports events, which would generally have competition as their primary focus, might also be perceived as HSEs. A comprehensive framework, built on a multi-disciplinary literature review, is presented to show the process that transforms an initial resource (a sports event) into an accomplished resource (a HSE), which might represent a competitive advantage for the territory. A qualitative–comparative analysis is conducted among 24 sports events in the French-speaking part of Switzerland, to observe the configurations of HSEs and understand which characteristics are necessary for the perceptions of a sports event as a heritage good. Interestingly, this contribution shows that if the event needs to be sustainable in the territory to be perceived as a HSE, it is not sufficient. Indeed, a differentiation strategy should be set up to distinguish the event from other more or less similar events, to be perceived as an authentic feature of the territory by the local population.     

Exploring athletes’ perceptions of coach stress in elite sport environments

The present study aimed to extend research that has focused on the identification of stressors associated with coaching practice by systematically evaluating how such stressors effect athletes, and more broadly, the coach–athlete relationship. A total of 13 professional- and national-level athletes were interviewed to address the three study aims: how they detect when a coach is encountering stressors, how coach experiences of stress effects them as an athlete, and how effective the coach is when experiencing stress. Following content analysis, the data suggested athletes were able to detect when a coach was experiencing stress and this was typically via a variety of verbal and behavioural cues. Despite some positive effects of the coach experiencing stress, the majority were negative and varied across a range of personal influences on the athlete, and effects on the general coaching environment. It was also the broad view of the athletes that coaches were less effective when stressed, and this was reflected in performance expectations, perceptions of competence, and lack of awareness. The findings are discussed in relation to the existing theory and with reference to their implications for applied practice, future research, and development of the coach–athlete relationship.     

A knock to the system: A new sociotechnical systems approach to sport-related concussion

Broader contextual factors that influence concussion management have tended to be overlooked. To address this, the present study used a sociotechnical systems approach to identify perceived responsibilities and applied strategies for three domains of concussion management (i.e., prevention, identification and treatment). Participants were 118 members of the community rugby union system in Australia (69.2% male). Participants from throughout the rugby system (e.g., players, parents, coaches, club management) were asked open-ended questions about their perceived responsibilities and the strategies they use for concussion management. It was found that (a) proper training, technique correction and education were recurrent prevention themes; (b) the majority of key stakeholders felt that they could consistently identify concussion; however, medical aids (medics) were the only system actors who stated a responsibility to use standardised concussion assessment measures and (c) less than one third of the respondents indicated their involvement in treating concussion. This study identifies specific junctures in the system that prevents effective concussion management strategies. A sociotechnical systems approach improves the understanding of concussion prevention, and management beliefs and behaviours.     

Student Management of Web-Based Hypermedia Resources During Open-Ended Problem Solving

Abstract

Twelve middle school students' use of computer tools to manage and manipulate Internet-based hypermedia resources was investigated. Tools were proposed to support higher order thinking about hypermedia resources to help students find, frame, and resolve open-ended science problems. Tools alone were insufficient to help students manage hypermedia information for solving open-ended problems. Students more frequently applied lower order tool functions (e.g., information collection) than higher order tool functions (e.g., reasoning). Students typically resolved problems with original solutions, but tools were used infrequently to develop evidence-based arguments justifying new ideas. Computer tools alone may be insufficient to help students manage extensive hypermedia resources. Together with additional support structures, however, tool potential may be realized.     

Globalization,public policy,and ‘knowledge gap’: Ethiopian youth and the HIV/AIDS pandemic

Set against trans‐ or supra‐national policy initiatives which have framed the HIV/AIDS pandemic as in part a pedagogical issue, this paper critically explores local understandings of sexual practices (generally) as well as of HIV/AIDS (more specifically) among young people in the sub‐Saharan African country of Ethiopia. Ethiopia has the third largest number of HIV/AIDS infections in the world, behind only South Africa and India. Like many countries dealing with this pandemic, the Ethiopian government has articulated its response to a broader set of global presses, including those around information and education. Such responses, we will argue, are helpful but have important limitations. As this study shows, knowledge about safer sex practices and the dangers of HIV/AIDS are by now well known among many Ethiopian youth. Yet, this knowledge does not always effect behavioral change. Taking condom use as a key exemplar, we will look at how Ethiopian youth narrate their own sexual experiences, conduct, and practices. Deeply informed by the work of Pierre Bourdieu, we look to open new ‘thinking tools’ for a range of actors addressing this global pandemic in situated contexts. In particular, we challenge the ‘pedagogical subject’ – a subject lacking key information – interpolated into many of these policies. We highlight, instead, new disjunctures between emergent discourses around sex and sexuality as well as long‐standing, conservative attitudes toward gender.     

媒介内容分析的相关理论

媒介内容分析作为传播学研究解决特定课题的辅助性工具和手段而存在,特定传播研究课题的理论定位和价值取向便决定了它的差异性,形成彼此不同甚或相互冲突的内容分析目的和指向。传统内容分析的根本特征或它的有效性,最终还是体现在贝雷尔森定义中的“显现传播内容”和“描述”这两个中心词的关系之上。它的最成问题之处在内容的分类上。结构主义／符号学方法,在处理定性的媒介内容时,无疑要比传统内客分析略胜一筹。它能描述媒介内容深层或潜隐的结构关系,显示信息传播过程必然涉及的文化意义。媒介内容分析的多种方法或可能性,显示它的任何结果都具有相对性。
