Galatzer‐Levy and Cohler's (1993) definition of “ self” allows for the possibility of a “ plural self,” that is, moments when an individual locates the center of initiative for action, feeling, and awareness among a group of people. Using observations and interviews, this investigation explores the ways four basketball teams used players’ bodies to create such a plural self, transforming autonomous individuals into interconnected, deindividualized members. One set of somatic practices made the team perceptible as a whole: huddles, team movements, hand slapping, and certain passing drills. A complementary set of practices encouraged the players to incorporate the team into their bodies. Examples presented of such incorporation are communal relaxation of bodily tension, the rhythms of shared ritual music, and a “sixth sense” of the location of teammates. Acute pain interferes with the emergence of this plural self in both injured and healthy players. The possibility is raised that for many athletes this temporarily realized plural self continues as a possible self and invites the development of certain virtues and failings.  相似文献

The importance of early literacy instruction and its role in later reading proficiency is well established; however, measures and procedures to screen and monitor proficiency in the area of early literacy are less well researched. The purpose of this study was to (a) examine the technical adequacy and validity of early curriculum-based literacy measures, Letter–Sound Correspondence, Onset Phoneme Identification, and Phoneme Segmentation, developed for use within the problem-solving model in the Minneapolis Public Schools and (b) describe the district-wide implementation of these measures. In general, these measures were found to have adequate reliability and validity, have moderate to moderately high correlations with criterion measures (oral reading, report cards), and be sensitive to growth across the school year. A case study of how these measures are used for screening and progress monitoring to improve reading achievement within 1 school is included. Limitations and future directions are also presented.  相似文献

Project GRAD (Graduate Ready for Activity Daily) evaluates a university course to promote physical activity. In a randomized study, 338 university seniors participated in either an intervention or control course for academic credit, and posttest data were collected on 321. The control course was knowledge-oriented. The intervention course taught behavior change skills in weekly lectures and peer-led labs. Physical activity was assessed with 7-Day Physical Activity Recall interviews. The intervention had no significant effects on men. Among women, the intervention increased total physical activity during leisure, strengthening exercises, and flexibility exercise. This university course had the intended effects of promoting healthful patterns of physical activity among women, but no effects were observed on men, who were more active than women at baseline.  相似文献

The purpose of this study was to determine whether there is a significant difference in the co-efficient of friction (Fc) between old versus new wrestling shoes and mats and to investigate the effect of perspiration. Fc was measured by dragging a weighted shoe over a wrestling mat surface and measuring the vertical and horizontal forces produced. Three different shoe conditions were assessed over two mat types for both wet and dry conditions for a total of 12 conditions. To simulate the wet condition, saline solution was smeared over the surface of the mat. There was a significant effect of shoe, mat, and wet/dry conditions. In addition, significant interactions of shoe by mat, shoe by dry/wet, and mat by dry/wet were observed. Overall, Fc was 36% higher for the new wrestling mat compared to the old wrestling mat. Application of the saline solution reduced Fc by 14% compared to the dry condition. Comparison of the mean Fc for all three shoe types revealed the Fc for the older design shoe was 23% to 28% lower than the brand new shoe and the worn newer design, respectively. A high Fc, such as in the new mat/new shoe combination, has the potential to increase the risk of knee and ankle injuries by fixing the foot more securely to the ground.  相似文献

The kinematic analysis of competition breaststroke swimming has tended to focus on the mean values of swimming speed, stroke rate and stroke length; values in individual lengths, as well as the start, turns and finish, have largely been ignored. This study includes all such variables and aims to improve the coach's holistic understanding of breaststroke racing by determining the relationships and differences between and within these selected kinematic variables. We also compare 100-m events with 200-m events to determine if there are characteristic differences between them. Competitive breaststroke swimming performances in 100-m events (males: n = 159, finishing time = 65.05 +/- 2.62 s; females: n = 158, finishing time = 74.04 +/- 3.66 s) and 200-m events (males: n = 159, finishing time = 141.47 +/- 6.15 s; females: n = 158, finishing time = 158.66 +/- 7.87 s) were collected and analysed from 12 world, international and national championships. The better 100-m and 200-m breaststroke swimmers were found to demonstrate greater competency in the kinematic variables measured, except stroke kinematics, which were unique to each individual. These findings suggest that coaches should place emphasis on all of the kinematic components in training and that they should attempt to identify the stroke rate to stroke length ratio most appropriate for the individual. Finally, characteristic differences do exist between the 100-m and 200-m events, which has implications for how swimmers might train for each event.  相似文献
