Cheating and rule violations in intercollegiate athletics continue to be relevant issues in many institutions of higher education because they reflect upon the integrity of the institutions in which they are housed, causing concern among many faculty members, administrators, and trustees. Although a great deal of research has documented the numerous rule violations in NCAA intercollegiate athletics, much of it has failed to combine sound theory with practical solutions. The purpose of this study was to examine the possible extensions of the organizational justice framework to the problem of rule violations in intercollegiate athletics. In doing so, the current study examined (a) perceived areas of injustice among coaches at NCAA Division I institutions, (b) avenues by which coaches resolve these injustices, and (c) potential solutions for resolving injustices in an attempt to reduce NCAA violations. Six NCAA Division I basketball coaches from various parts of the country (four from men's teams and two from women's teams) were interviewed using a semi-structured format. Despite the NCAA's efforts to create parity, results showed that coaches perceived several areas of inequities in recruiting, including financial resources and academic standards. The interviewed coaches described several means that are currently used to resolve these inequities and offered recommendations for changes to reduce injustice in the future.  相似文献

The effect on gross locomotor activity of irrelevant stimuli, prior exposure to these stimuli and two dosages of amphetamine were assessed on rats with lesions in the dorsal hippocampus. These animals were significantly more active post-operatively than sham-lesioned subjects. Prior exposure to the irrelevant stimuli increased post-operative differentiation between stimuli, whereas the introduction of amphetamine had the reverse effect. Changes in locomotor activity occurred at lower dosages of amphetamine than in previous studies, suggesting that the irrelevant stimuli have an arousal effect which acts additively with amphetamine and hippocampal impairment.  相似文献

Three experiments were done to test the hypothesis that the spacing effect results from a voluntary decision by the subject to pay little attention to the second presentation (P2) of an item when it occurs shortly after the first (P1)- In all three experiments, the spacing of repetitions was varied. In Experiment I, allocation of attention was manipulated by pairing P2 of some pictures with a signal that indicated high payoff for later retention. In Experiment II, attention was controlled more directly by requiring the subject, in one condition, to recite words aloud. In both experiments, the dependent variable was judged frequency. In neither experiment did the effect of the attention manipulation interact with that of the spacing of repetitions. In Experiment III, the number of eye fixations given a picture was taken to be a measure of attention. The number of fixations dropped from P1 to P2 to P3, but was unaffected by the spacing of repetitions. The experiments provide no support for a voluntary attention explanation of the spacing effect.  相似文献

As adolescent anxiety is common and costly, identifying effective strategies to reduce symptoms is a priority. This study tested whether adolescents could learn to use cognitive reappraisal strategies to attenuate fear during extinction learning. Fifty-seven participants (12–15 years) viewed images of two neutral faces, one which was paired with a fearful expression and shrieking scream (conditioned threat stimulus) and the other that was never paired with the aversive outcome (conditioned safety stimulus) during fear acquisition. Before extinction, participants either received cognitive appraisal training, which explored alternative, benign meanings associated with the scream or a control activity. Self-reported fear ratings in the cognitive reappraisal group were significantly lower to both the conditioned threat and safety stimuli after extinction than the control group. These findings did not characterise fear-potentiated startle data. Potential reasons for the lack of consistency between measures are considered.  相似文献

In an era of specialty medicine, genetic counselors are becoming increasingly focused in their service provision. The Alpha-1 Association Genetic Counseling Program, established in September 2007, specializes in confidential toll-free genetic counseling provided by a certified genetic counselor for Alpha-1 Antitrypsin deficiency, a co-dominant condition associated with lung and/or liver disease. The program received more than 600 callers in its first 2 years. Sixty-seven percent of new callers were family members, carriers, or health professionals. The number of callers increased between the first 2 years, with the greatest increases being family members and health professionals. Testing options and explanation of results encompassed 60% of initial reasons for calls. Seventy-two percent of referrals came from family and friends, test result letters, and the Alpha-1 Association. Between year 1 and 2 family member referrals showed the largest increase. This disease-specific genetic counseling program provides a model that may be useful for other rare disease communities.  相似文献
