Abstract

At the 2012 Olympic Games, eight badminton players were disqualified from the women’s doubles tournament for intentionally losing matches in the group stage. The incident marks the largest mass disqualification of athletes from multiple countries for match-fixing at the Olympic Games in the twenty-first century. Significantly, it is also the first time that female athletes have been disqualified from a Summer Olympic Games for match-fixing not related to betting or gambling. This essay weaves together two interdependent arguments. First, it is suggested that the incident can be understood through the lens of three separate but interconnected issues: the history of match-fixing, the growth of code of conduct documents in sports, and the regulation of women’s bodies in sports. Second, it is argued that the athletes’ gender is a critical element of the incident. The primary aims of the article are to position the 2012 badminton scandal as a key moment in the history of match-fixing and to suggest that the incident is important for future research and policy creation.  相似文献

A longitudinal study was performed to determine differences in physiologic variables, health behaviors, risk factors, or clinical status between former athletes (FA) (N = 345) and nonathletes (NA) (N = 75). The subjects, 420 self-referred white males aged 25-60 years old, were examined for prior athleticism and health. Athleticism was determined through self-reported high school or college athletic history. Baseline physiologic and health behavior characteristics were not different between the two groups. Of those study participants (N = 203 FA, 48 NA) who were sedentary at baseline, 208 (N = 167 FA, 41 NA) voluntarily began an exercise program during the followup period (average followup = 56 months). These numbers correspond to exercise adoption rates of 82 and 85% for FA and NA respectively, and were not statistically different (95% CI FA = 0.76, 0.88, NA = 0.73, 0.97). Repeated measures analysis of covariance was performed to determine if physiologic responses to adoption were different between FA and NA. No statistically significant difference was found between the two groups, time effects were similar in the two, and no significant interaction of time by group was observed. We conclude that prior athleticism has little apparent impact on health and health behaviors, thus suggesting that contemporaneous exercise has more impact on clinical variables.  相似文献

Abstract

This study introduces a novel application of structural equation modeling (SEM) for the analysis of cortisol data that are collected using a pre–post–post design. By way of an extended example, an SEM model is developed that permits an examination of both the overall level of cortisol, as well as changes in cortisol (reactivity and regulation), as predictors of cognitive (executive) and behavioral functioning in 3- to 5-year-old children (N = 171) attending Head Start. The SEM model makes use of the parameterization of latent curve models. Throughout the extended example, the strengths of using an SEM approach for the analysis of cortisol data that are collected using pre–post–post designs is highlighted.  相似文献

This study examines whether changes in classroom quality predict within-child changes in achievement and behavioral problems in elementary school (ages spanning approximately 6–11 years old). Drawing on data from a longitudinal study of children in predominantly low-income, nonurban communities (n = 1,078), we relied on child fixed effects modeling, which controlled for stable factors that could bias the effects of classroom quality. In general, we found that changes in classroom quality had small and statistically nonsignificant effects on achievement and behavior. However, we found that moving into a high-quality classroom, particularly those rated as high in Classroom Organization, had positive effects on achievement and behavior for children with significant exposure to poverty in early life.  相似文献

The critical role of communication in schools cannot be understated. Communication skills are a necessity both in the academic and social atmosphere of the school environment. Unfortunately, there are a large number of children in the schools today identified with speech and language disorders. This special edition of Psychology in the Schools examined issues that impact the academic and social functioning of such children. Several articles are focused on potential early intervention strategies or services surrounding literacy and social skills that may enhance the success of children with communication disorders and/or at risk for communication disorders (e.g., Chapman, Denning, & Jamison, 2008; Thatcher & Fletcher, 2008; van Kleeck, 2008). Two other articles tackle promising strategies that may be used in academic settings with children who stutter (Logan, Mullins, & Jones, 2008) or with children with cognitive impairments (Gillette & DePompei, 2008). Despite promising avenues of intervention and practice, there are also barriers to providing instruction to children with communication disorders in a regular classroom (Pufpaff, 2008). Each article provides insight into the importance of communication skills for academic and social success in the schools. The key to the success of children with or at risk for communication is for all school personnel to be aware of and proactive with children with communication disorders. © 2008 Wiley Periodicals, Inc.  相似文献

This article examines findings from a qualitative investigation of how school district administrators in four mid to large sized urban school districts (10,000–50,000) identify and address differences in school performance. The analysis explores the interaction between district policies and actions that centralize and standardize expectations for teaching, learning, and leadership, and those that lead to the differentiation of district support to schools depending upon their identified needs. The findings demonstrate variability in district orientation and capacity to understand school needs to improve performance, as well as in district strategies for actually differentiating support to schools. Differentiated assistance can focus both on strengthening implementation of district expectations in order to improve school performance, and on supporting experimentation with non-standard solutions to performance challenges that are not solvable through use of established programs and practices.  相似文献

BackgroundProfessional health organizations are not currently recommending Tai Ji Quan alongside aerobic exercise to treat hypertension. We aimed to examine the efficacy of Tai Ji Quan as antihypertensive lifestyle therapy.MethodsTai Ji Quan interventions published in English and Chinese were included when they involved healthy adults, reported pre- and post-intervention blood pressure (BP), and had a non-exercise/non-diet control group. We systematically searched 11 electronic databases for studies published through July 31, 2018, yielding 31 qualifying controlled trials. We (1) evaluated the risk of bias and methodological study quality, (2) performed meta-regression analyses following random-effects assumptions, and (3) generated additive models representing the largest possible clinically relevant BP reductions.ResultsParticipants (n = 3223) were middle-aged (56.6 ± 15.1 years of age, mean ± SD) adults with prehypertension (systolic BP (SBP) = 136.9 ± 15.2 mmHg, diastolic BP (DBP) = 83.4 ± 8.7 mmHg). Tai Ji Quan was practiced 4.0 ± 1.4 sessions/week for 54.0 ± 10.6 min/session for 22.3 ± 20.2 weeks. Overall, Tai Ji Quan elicited significant reductions in SBP (–11.3 mmHg, 95%CI: –14.6 to –8.0; d+ = –0.75) and DBP (–4.8 mmHg, 95%CI: –6.4 to –3.1; d+ = –0.53) vs. control (p < 0.001). Controlling for publication bias among samples with hypertension, Tai Ji Quan trials published in English elicited SBP reductions of 10.4 mmHg and DBP reductions of 4.0 mmHg, which was half the magnitude of trials published in Chinese (SBP reductions of 18.6 mmHg and DBP reductions of 8.8 mmHg).ConclusionOur results indicate that Tai Ji Quan is a viable antihypertensive lifestyle therapy that produces clinically meaningful BP reductions (i.e., 10.4 mmHg and 4.0 mmHg of SBP and DBP reductions, respectively) among individuals with hypertension. Such magnitude of BP reductions can lower the incidence of cardiovascular disease by up to 40%.  相似文献
