Abstract The purpose of this investigation was to study the intelligence and skill of 375 college women in relation to their success in round-robin singles competition in badminton or tennis. Intelligence was measured by the Otis quick-scoring mental ability test; skill was determined by the subject's combined T-score on two standardized tests of badminton or tennis skill; and success in tournament play was expressed by the percentage of points won out of the number possible during tournament play. Prior to the competition, subjects were classified on the basis of skill by means of a skill test and placed into leagues of between eight and eleven players each. Tests of equivalence were applied to determine the equality of leagues with respect to skill and intelligence. An analysis of variance employing success as the dependent variable and involving two levels of skill and intelligence (high and low) and two levels of sport (badminton and tennis) resulted in a highly significant F ratio for the skill variable and nonsignificant F ratios for intelligence and sports. Interaction factors were generally nonsignificant. Correlation coefficients between skill and success in badminton and tennis were .65 and .60 respectively, and coefficients between intelligence and success were essentially zero. 相似文献

This study tested the reliability of nine scales assessing psychosocial mediators of HIV-risk and protective behaviors of young minority women in New York City. Sixty-nine age-eligible women were approached during clinical sessions, 90% (n = 62) agreed to participate, and 83% (n = 57) completed a web-based survey. With one exception, scale measures were reliable. The exception was the scale assessing frequency of sexual communication with partners. This scale did not demonstrate adequate interitem reliability for Black women. Findings provide program planners with a reliable set of measures that may be useful for preintervention needs assessments of young minority women at-risk of acquiring HIV. 相似文献

ABSTRACT This study investigated the between-limb asymmetry in kinetic and temporal characteristics during bilateral plyometric drop jumps from different heights. Seventeen male basketball players performed drop jumps from 3 heights on two platforms in randomized orders. Vertical ground reaction force data were analysed with respect to the lead limb (i.e. the limb stepping off the raised platform first) and trail limb. Peak forces and loading rates of each limb were calculated. The absolute time differential between the two limbs at initial ground contact and takeoff were determined. The frequency of symmetrical landing and taking off with “both limbs together” were counted using 3 time windows. Results showed that the lead limb displayed higher peak forces and loading rates than the trail limb across all heights (p <.05). As drop height increased, the absolute time differentials decreased at initial ground contact (p <.001) but increased at takeoff (p =.035). The greater the preset time window, the more landings and takeoffs were classified as bilaterally symmetrical. In conclusion, higher drop heights allowed subjects to become more bilaterally symmetrical in the timing of landing but this reduction in temporal asymmetry did not accompany with any reduction in kinetic asymmetry. 相似文献

This paper discusses several approaches to Web-based learning, on-line learning and IT instruction that have been implemented at the University of Hawaii, including studio-based learning, techniques for implementing critical evaluation skills when utilizing on-line sources, virtual museum use, the use of metacognitive prompts in on-line instruction and outreach to other Pacific Island communities. The paper also addresses aspects of ICT and on-line instruction and community building in multicultural settings that represent some of the most geographically isolated regions on the planet, with socioeconomic disparities spanning the digital divide. This paper shows how technology can be used to promote higher order thinking, metacognition and critical evaluation skills that encourage students to use ICT in more discriminatory and evaluative ways. The paper also shows that using virtual museums for sharing cultural knowledge and using metacognitive prompts for critical analyses are other ways of enriching knowledge through the use of the Internet. Furthermore, technology can be used for communicating with different populations regardless of income or ethnicity, and the Internet can improve access to higher education for rural populations that would not consider university access a possibility without being provided with the support that technology can give. 相似文献

This article proposes the use of a new technology to assure student anonymity and reduce bias hazards: identifying students by using bar codes. The limited finding suggests that the use of bar codes for assuring student anonymity could potentially cause students to perceive that grades are assigned more fairly and reassure teachers that they are avoiding identity bias to the greatest extent possible. The authors recommend further implementation of bar code usage to investigate whether students and faculty could achieve positive perceptions as well as whether there are any drawbacks to such use. 相似文献

OBJECTIVE: This study assembles information about the large number of maltreatment reports that are determined by social services to be unsubstantiated. Specifically, we assess whether the status of a maltreatment case (substantiated vs. unsubstantiated) has implications for recidivism. Recidivism rates for substantiated and unsubstantiated maltreated juveniles were also compared to juvenile offenders. METHOD: Juvenile court records for 15,812 juveniles were assessed over a 3 year period. The data included 2558 maltreatment cases. Fifty-four percent of these cases were unsubstantiated. Logistic regression analysis was employed to assess the probability of recidivism based on time one referral status. RESULTS: Youth whose maltreatment allegations were unsubstantiated had significantly lower odds of recidivating than abused youth. Having a case recorded as unsubstantiated lowered a youth's odds of subsequent offending by 55% relative to being abused. The probability of recidivating was highest for juvenile offenders, followed in order by maltreated youth and youth whose reports were unsubstantiated. DISCUSSION: This is one of the first studies to examine the court histories of substantiated and unsubstantiated maltreatment cases. If the subsequent outcomes following maltreatment investigations are used as an indicator of seriousness, our results suggest that assessment caseworkers are successfully sorting out the serious from the less serious cases. 相似文献

A theoretical scheme was suggested which distinguished between absolute and relative class concepts and differentiated class from relational concepts. Four monkeys were trained to respond differentially to green and nongreen objects (absolute class) and four responded differentially to odd and nonodd objects (relative class). All monkeys met stringent criteria of performance on their respective tasks, the green-nongreen group in a median of 600 trials and the odd-nonodd group in a median of 1,600 trials (p = .014). Possible explanations for the performance differences and some implications of the theory for comparative, nonhuman conceptual research were discussed. 相似文献
