The objective was to investigate the relationship between IL-1B rs16944, IL-6 rs1800795, and CASP8 rs3834129 genetic polymorphisms and concussion severity. Rugby players from high school, senior amateur, and professional teams completed a concussion severity questionnaire and donated a DNA sample. Participants (n = 163) were split into symptom severity groups around the median number and duration of symptoms. The frequency of participants with high symptom counts (more than five symptoms) increased across the IL-1B (C/C: 35%; C/T: 51%; T/T: 56%; P = 0.047) and the IL-6 (C/C: 31%; C/G: 44%; G/G: 58%; P = 0.027) genotypes. The C–C inferred interleukin allele construct frequency, created from combining the IL-1B and IL-6 genotype data, was lower in participants reporting a high symptom count (18%), compared to those with a low symptom count (fewer than six symptoms, 36%, P = 0.002). Similarly, the C–C inferred interleukin allele construct frequency was lower in those reporting prolonged symptom duration (more than one week, 16%), as opposed to short symptom duration (less than one week, 34%, P = 0.015). This study provides evidence of novel inflammatory pathway genetic associations with concussion severity, which supports the hypothesis implicating neuroinflammation in the development of concussion symptoms.  相似文献   

Examining the antecedents of sport team brand equity: A dual-identification perspective     

Michael Chih-Hung Wang  Ya-Yun Tang 《Sport Management Review》2018,21(3):293-306

Although the practice of building brand equity in the context of professional sport teams is popular, the formation of sport team brand equity in the sport marketing literature is still relatively unknown and incompletely understood. In this study, the authors propose a dual-identification model to examine the formation of sport team brand equity in an Asia-based professional team sport setting. Baseball fans (N = 548) of the Chinese Professional Baseball League (CPBL) in Taiwan participated in the self-administered survey. A Partial Least Squares Structural Equation Model analysis revealed that marketplace characteristics (including group experience, salient experience, team history, and fan rituals) and brand-identified-related factors (including self-congruity and team brand prestige) were significantly related to identification with sport team and identification with sport team brand, respectively. In turn, both identification with sport team and identification with sport team brand were significant predictors of sport team brand equity. These findings highlight the importance of studying a dual-identification model in order to understand how sport team brand equity forms and suggest implications for sport team managers.  相似文献   

Leveraging community sport organizations to promote community capacity: Strategic outcomes,challenges, and theoretical considerations     

Gareth J. Jones  Michael B. Edwards  Jason N. Bocarro  Kyle S. Bunds  Jordan W. Smith 《Sport Management Review》2018,21(3):279-292

Community sport organizations (CSOs) provide valuable contexts for promoting community development. These initiatives are most effective when they involve local stakeholders in the process of development. A key first step to achieving this objective is building community capacity, defined as local stakeholders’ skills, knowledge, and resources that may be leveraged for change. Interestingly, despite this conceptual importance, few researchers have focused on capacity building in the sport context. This has limited the theoretical advancement of community capacity theory as it relates to CSOs and community development. Using a qualitative case study approach, the authors analyze the outcomes and challenges of implementing community capacity building strategies in an American CSO, and draw on the empirical data to contribute to this theoretical conversation. Interviews, participant observation, and document analysis were used to generate data, and deductive techniques were used for thematic analysis. The results highlight the outcomes of the capacity building strategies and challenges associated with implementation. In addition, the conclusion focuses on theoretical contributions to community capacity theory, namely the role of sport in facilitating inter-community relations across social groups and the link with process models of organizational capacity.  相似文献   

Match-Fixing in Cornish Wrestling during the Nineteenth and Early Twentieth Centuries     

Michael Tripp 《国际体育史杂志》2018,35(2-3):157-172

Abstract

During the first half of the nineteenth century, Cornish wrestling, which was distinctive to Cornwall, was the county’s most popular sport, with a large number of wrestlers competing for lucrative prizes at numerous tournaments and watched by thousands of spectators. Its popularity also extended to London, where sporting entrepreneurs, mainly publicans, organized and promoted wrestling in the Cornish style, when the best wrestlers were lured to the capital to compete for large prizes, witnessed by substantial crowds, which often included members of the nobility. During the second half of the nineteenth century, Cornish wrestling suffered a serious decline in popularity with fewer wrestlers, tournaments, and spectators. By 1900 the sport had almost died out and only survived due to the efforts of a small group of talented wrestlers who inspired a minor revival in the years leading up to 1914. One factor that contributed to the decline was the practice of ‘faggoting’, which was a form of match-fixing that involved wrestlers agreeing with opponents to share any prize money. Consequently, the sport developed a bad reputation and became very unpopular with spectators. In order to eradicate the practice, wrestling organizers issued regular warnings to wrestlers or excluded them from tournaments.  相似文献   

Can alcohol sponsorship be diluted by health messaging?     

Sarah Jane Kelly  Michael Ireland  John Mangan  Harley Williamson 《Sport in Society》2018,21(3):434-451

Concerns surround the association between alcohol advertising and alcohol consumption amongst audiences. Research has examined the link in broadcast sports, yet limited attention is directed towards newer media. This paper examines whether there is a link between alcohol sponsorship in sports games and alcohol brand recall, recognition and choice, and whether in-game health messages moderate this association. Simulated games designed specifically for this study are used to observe whether in-game alcohol sponsorship combined with embedded health messages affect the player’s brand awareness. Findings highlight the influence of in-game alcohol sponsorship placement on brand awareness, yet embedded health messages do not impact consumer behaviours. This research provides evidence suggesting regulations in games may be warranted and further examination of health messaging in sponsor brand placement necessary.  相似文献   

Testgütekriterien der „Profilanalyse nach Grießhaber“. Evaluation eines Verfahrens zur Erfassung grammatischer Fähigkeiten von ein- und mehrsprachigen Grundschulkindern     

Birgit Ehl  Michèle Paul  Gunnar Bruns  Elisabeth Fleischhauer  Miriam Vock  Anna Gronostaj  Michael Grosche 《Zeitschrift für Erziehungswissenschaft》2018,21(6):1261-1281

A diagnostic goal of the “Profile analysis according to Grießhaber” is the assessment of the grammatical ability to place verbs in German sentences in the correct syntactical position. To evaluate the test quality for the first time, 403 monolingual and multilingual primary school children were randomly assigned to three different test materials: Test material that specifically stimulated the target competence led to the best test results. This indicates a low objectivity of application. In addition, ceiling effects for primary school children were detected, which means that the profile analysis can only slightly differentiate among the grammatical abilities of the children. Retest reliability and objectivity of analysis are also too small. In summary, the test quality of the assessment tool should be improved with respect to all of the test quality criteria considered. Hence, we recommend standardizing the profile analysis better and adding more sensitive diagnostic criteria for primary school aged children. Other aspects of profile analysis, for example the improvement of diagnostic competencies of teachers, are recommended for future research.  相似文献

Inquiry-based learning in China: Do teachers practice what they preach, and why?   总被引：1，自引：0，他引：1  

David Yun Dai  Kathryn A. GERBINO  Michael J. DALEY 《Frontiers of Education in China》2011,6(1):139-157

China is undergoing an education reform that calls for a change from a rigid, fixed curriculum and didactic pedagogy to a more flexible, school-based curriculum and more inquiry-based pedagogy. This study investigated the extent to which Chinese middle and high school teachers (a) endorse an inquiry-based approach and underlying learning principles, (b) practice this mode of teaching, and (c) believe that the approach is practically viable in the current educational contexts in China. A structured survey was developed to solicit Chinese teachers’ responses to the above three issues. A total of 582 valid responses were collected, representing middle and high schools in different geographic locations. The results show that Chinese teachers are receptive to inquiry-based pedagogy but find practical constraints in fully implementing it. Several cultural and pragmatic reasons are explored. Policy implications are discussed with respect to teacher education/development, capacity building for the new pedagogy, and teaching/evaluation alignment. Finally cultural issues are discussed regarding using inquiry-based learning to enhance critical thinking and nurture independent thinkers.  相似文献   

A novel approach to the dissection of the human knee     

F. Richard Clemente  Philip A. Fabrizio  Michael Shumaker 《Anatomical sciences education》2009,2(1):41-46

The knee is one of the most frequently injured joints of the human body with injuries affecting the general population and the athletic population of many age groups. Dissection procedures for the knee joint typically do not allow unobstructed visualization of the anterior cruciate or posterior cruciate ligaments without sacrificing the collateral ligaments. In many cases, the relationships of the intraarticular structures are lost as dissection systematically removes superficial structures to gain access to deeper structures. The authors present an alternative technique for dissection of the human knee joint that allows maximal visualization of intraarticular structures such as the cruciate ligaments and menisci with minimal disturbance to the tibial and fibular collateral ligaments, thus preserving the relationships of the ligamentous and intraarticular structures.
