许多运动队将全程比赛分析作为教练员的指导工具,研究己方和对方运动员的类型、战术和技术特点.网球项目中,拥有个人分析师的运动员并不多见,大部分运动员和教练员使用分析设备和程序提供的客观、可靠的反馈信息,自己进行赛前及赛后分析.很多教练员采用其他教练员的有效训练模式,因为不是所有人都有时间去分析1000h的大满贯录像来找出战术差异,但可利用他人的分析结果.赛事录像记录的客观数据提供了充足的反馈信息,教练员可根据这些反馈信息调整技战术,进行针对性的训练. 相似文献

Ninety-nine NASP members participated in a study designed to investigate bias in the early stages of the referral process (i.e., in the decision to administer psychological tests). Each school psychologist received one of eight case studies, which described a child referred for academic learning problems. The case studies included typical referral information and varied student race (Black, White), socioeconomic status (higher, lower), and group achievement test scores (average, below average). The decision to administer individual psychoeducational tests was not influenced by the student's race or socioeconomic status. School psychologists were influenced by the group achievement test data. Students who showed lower achievement test results were more likely to be recommended for testing than were those who showed average performance levels. Thus, these school psychologists were not biased by knowledge of a child's race or socioeconomic status, but were influenced by instructionally relevant data (i.e., achievement test scores). In addition, when objective test data indicated average achievement levels, the psychologists did not generally recommend subsequent individual psychoeducational testing. The findings suggested that, under certain conditions, testing may not automatically follow receipt of a referral. 相似文献

The Fourth Edition of the Stanford-Binet and the WISC-R were compared as instruments for assessing the intellectual strengths and weaknesses of students classified as learning disabled in the primary and secondary grades. Results found only a 3.28-point difference (p≥.0001) between the S-B Composite score and the WISC-R Full Scale score. Correlations between the four broad areas of the S-B and the three scales of the WISC-R ranged from .494 (S-B Abstract/Visual Reasoning with WISC-R Verbal) to .920 (S-B Composite with WISC-R Full Scale). All correlations were found to be significant. Implications of the research findings were discussed. 相似文献

This study assessed the differential contribution of personality to the explanation of variance in achievement in the mother tongue and mathematics at the high school level. The results indicated that personality, as measured by the HSPQ, aided the explication of variance in achievement in the mother tongue significantly, but had little influence on mathematics. Personality contributed as much to the explanation of variance in the mother tongue as did the composite cognitive variable. The influence of personality on achievement in mathematics was shown to be negligible. Some practical implications for the teaching of the first language are drawn. 相似文献

Compared intrachild variability of five-year-old children (49 black, 34 white) on the Primary Mental Abilities Test when subjects reached their fifth birthday after completing at least two years of preschool enrichment. Conclusions, although qualified on the basis of limited sample size, revealed wider intrachild variability with minority children. This suggests that abandonment of testing may increase instructional problems and possibly lower the quality of instruction provided minority and poor children. 相似文献

This essay builds on the growing, but underdeveloped, role of communication in work based on Social Identity Theory (SIT) as it relates to identity and identification in the organization. Five existing areas of connection between communication and SIT in organizational identification research are documented and assessed. These include salience of dual/multiple identifications, computer-mediated communication and virtual work related to identification, relationally focused work identities, organizational-level identities, and disidentification and related forms. 相似文献

AbstractIn the fall of 2017, the Clark Library at the University of Portland undertook an investigation of ethics in academic libraries to understand ethical practices in the library’s day-to-day work. The self-study was a year-long, library-wide project with directed activities within small groups, individually assigned readings and responses, and discussions at all-staff meetings. The project culminated in three specific deliverables: an annotated bibliography focused on ethical issues by functional area, a Clark Library Statement of Ethics, and a Statement of Ethical Information Use for inclusion in University syllabi. 相似文献

Abstract Body composition is a key consideration in the physical make-up of professional soccer players. The aims of the present study were to determine whether the body composition of professional soccer players varied according to playing position, international status or ethnicity, and to establish which variables best distinguished the soccer players from a reference group. Body composition was assessed using dual-energy X-ray absorptiometry in 64 male professional soccer players. Measured variables included bone mineral density and the relative amounts of lean and fat mass. Data were analysed using analysis of variance and stepwise discriminant function. The soccer players recorded better values than a reference group (n = 24) for all body composition compartments. Percent lean mass and bone mineral density were the variables best able to identify the soccer players (95.5% correctly classified). Differences in body composition were evident between goalkeepers and outfield players, but not between outfield playing positions. No differences were found on the basis of international status. The non-Caucasian players demonstrated significantly lower percent body fat (9.2 ± 2.0%) than the Caucasian players (10.7 ± 1.8%). It was concluded that body composition is important for elite soccer players, but that homogeneity between players at top professional clubs results in little variation between individuals. 相似文献
