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

Citrulline has been proposed as an ergogenic aid, leading to an interest in watermelon given its high citrulline concentration. The aim of this study was to determine the effects of a single, pre-exercise dose of l-citrulline, watermelon juice, or a placebo on the total maximum number of repetitions completed over 5 sets, time to exhaustion, maximal oxygen consumption (VO2max), anaerobic threshold, and flow-mediated vasodilation. A randomised double-blind within-participants study design was used to examine these effects among 22 participants (n = 11 males). Supplementation included either a 7.5% sucrose drink containing 6 g of l-citrulline, 710 mL of watermelon juice (~1.0 g citrulline), or a 7.5% sucrose placebo drink. Supplementation was administered 1 or 2 h before exercise testing to investigate a timing effect. There was no significant effect between the three supplements for the total number of repetitions, time to exhaustion, VO2max, anaerobic threshold, or flow-mediated vasodilation. There was also no interaction observed relative to gender or supplement timing (P > 0.05). A single dose of l-citrulline or watermelon juice as a pre-exercise supplement appears to be ineffective in improving exercise performance; however, greater doses of l-citrulline have been shown to be safe and are currently left unexamined. 相似文献

This paper discusses the relative merits of discrete versus continuous perspectives on innovation, technical change, and economic growth. It discusses the innovation time series literature in some detail to extract the continuous and clustering properties of the historical record on innovation. It then proposes a mosaic/avalanche model based on percolation theory and self-organized criticality to address this question. 相似文献

Assessment of the personalities of medical students could enable medical educators to formulate strategies for the best development of academic and clinical competencies. In this article, we focus on the experience of students in the anatomy dissecting room. While there have been many attempts to evaluate the emotional responses of medical students to human cadaveric dissection, there has been no investigation into how different personality traits affect the responses. The main hypothesis tested was that there is a relationship between personality traits and attitudes toward the dissection room. For the present study, a group of French medical students (n = 403; mean age 21.3 ± 1.6; 65.3% female) completed a "Big Five" personality inventory and a questionnaire to assess their attitudes in regard to human dissection. The findings are consistent with our hypothesis, in that we found a relationship between reporting anxiety and four of the "Big Five" dimensions (all except openness). The rated level of anxiety was positively correlated with negative affectivity, more strongly at the beginning than at the end of the course. There were significant gender differences in attitudes toward dissection. The findings are discussed in relation to the possibility of preparing students for the dissecting room experience and also in relation to the students' understanding of mortality issues. 相似文献
