Male teamsport athletes have traditionally been described as some of the most homophobic and femphobic men in North American culture. However, in this ethnographic research of an education-based soccer team at a small Catholic university in a rural part of Middle America, I use inclusive masculinity theory to highlight that a softer version of masculinity is in operation. I use participant observation and 22 in-depth interviews to show that these men are gay friendly, that they avoid fights, and that they use reciprocal disclosure and homosocial tactility to emotionally bond. Although the type of masculinity the men on this team exhibit retains some orthodox behaviours, it is nonetheless far removed from the traditional model of hegemonic masculinity commonly attributed to teamsport athletes found in American institutes of sport and education.  相似文献

Abstract

One result of globalization is that more of what people consume comes from distant regions through complex transactions hidden from ordinary view. To illuminate such flows, scholars often trace commodity chains following one product from inception to sale. Although most of us cannot escape being involved in commodity chains, we can participate with greater or less responsibility. This article outlines the advantages of studying the coffee chain to understand its relationship to consumer choice and environmental issues.  相似文献

The aim of this study was to quantify movement patterns of batsmen scoring 100 runs (century), including analysis at 50, 80, and 100 runs, in Test and One-Day international (one-day) matches and between the first and second 50 within a Test century. Test centuries (n = 13) and one-day scores above 80 (n = 12) filmed during the 2005 - 2006 Australian international season were analysed for movement patterns of standing, walking, jogging, striding, sprinting, shot playing, and turning. At each run target, differences in total time, duration of individual movement pattern, movement pattern frequency, and number of balls faced were determined between Test and one-day matches (analysis of variance). Differences within Test centuries were assessed using paired t-tests. A similar fractional predominance of time spent in low-intensity activity (standing and walking) between Test and one-day matches at each run target (94 and 96% respectively) was observed, with no differences in duration of striding or sprinting (Test: 1.1 min, s = 0.5; one-day: 0.9 min, s = 0.5 for sprinting: P = 0.28). A 37% longer total duration occurred in Tests, resulting in longer recovery bouts between high-intensity efforts. There were no differences between the first and second 50 runs of a Test century for any measure (P at best = 0.34). In summary, Test and one-day centuries are characterized by much low-intensity activity and patterns of high-intensity activity similar to many repeat-sprint team sports and greater recovery breaks in longer matches.  相似文献

The purpose of this study was to determine if a relationship exists between purposeful heading in soccer and neuropsychological test performance. Automated Neuropsychological Assessment Metrics throughput scores were derived on seven subset variables that measure a variety of neurocognitive abilities. Simple Spearman's rank correlations were calculated between headers per game (HPG) and the criterion variables. Interestingly, math processing speed (Spearman's rho = .160) and continuous performance test #2 (rho = .124) had small but significant correlations; both showed improvement in performance pre- to postseason. There were no significant correlations between HPG and the other five variables. This study found no detrimental relationship between the number of purposeful headers and the neurocognitive measures in this population.  相似文献

The determination of the ventilatory threshold has been a persistent problem in research and clinical practice. Several computerized methods have been developed to overcome the subjectivity of visual methods but it remains unclear whether different computerized methods yield similar results. The purpose of this study was to compare nine regression-based computerized methods for the determination of the ventilatory threshold. Two samples of young and healthy volunteers (n = 30 each) participated in incremental treadmill protocols to volitional fatigue. The ventilatory data were averaged in 20-s segments and analysed with a computer program. Significant variance among methods was found in both samples (Sample 1: F = 11.50; Sample 2: F = 11.70, P < 0.001 for both). The estimates of the ventilatory threshold ranged from 2.47 litres.min(-1) (71% VO2max) to 3.13 litres.min(-1) (90% VO2max) in Sample 1 and from 2.37 litres.min(-1) (67% VO2max) to 3.03 litres.min(-1) (83% VO2max) in Sample 2. The substantial differences between methods challenge the practice of relying on any single computerized method. A standardized protocol, likely based on a combination of methods, might be necessary to increase the methodological consistency in both research and clinical practice.  相似文献

Vallerand et al. (2003) developed a dualistic model of passion, wherein two types of passion are proposed: harmonious (HP) and obsessive (OP) passion that predict adaptive and less adaptive interpersonal outcomes, respectively. In the present research, we were interested in understanding the role of passion in the quality of coach-athlete relationships. Results of Study 1, conducted with athletes (N=157), revealed that HP positively predicts a high-quality coach-athlete relationship, whereas OP was largely unrelated to such relationships. Study 2 was conducted with coaches (N=106) and showed that only HP positively predicted the quality of the coach-athlete relationship. Furthermore, these effects were fully mediated by positive emotions. Finally, the quality of the coach-athlete relationship positively predicted coaches' subjective well-being. Future research directions are discussed in light of the dualistic model of passion.  相似文献

Feminist and hegemony theorizing are used to explicate how sport and its ancillary organizations and occupations have managed to reproduce its masculinized nature despite the gains of second wave feminism that characterizes the broader culture. The author shows that contemporary sporting institutions largely originated as a political enterprise to counter the first wave of feminism, and describe how gender-segregation and self-selection permits sports’ gatekeepers to near-exclusively draw upon a relatively homogenous group of hyper-masculine, over-conforming, failed male athletes to reproduce the institution as an extremely powerful gender-regime. The author suggests that, because orthodox notions of masculinity are institutionally codified within sport, it will take more than affirmative action programs to bring gender equality off the pitch; it will also require gender-integration on the pitch.  相似文献

The application of symmetrical components to the solution of steady state problems in power systems engineering suggests the application of the same or similar components in the study of transient phenomena on the network calculating board by means of oscilloscope and synchronous switch. However, it is found upon rigorous examination that symmetrical components are applicable to such problems in but a few types of switching. Part II of this paper will deal with a system of components which serve well in all cases of transient phenomena produced by short circuits, the operation of circuit breakers or other apparatus.  相似文献
