The authors recruited college students (N = 648) and investigated relationships among academic and social self–efficacy, relational aggression from parents and peers, and nonsuicidal self–injury (NSSI). Results indicated that both types of self–efficacy were related inversely to NSSI. Academic self–efficacy mediated the relationship between parental emotional abuse and NSSI, whereas social self–efficacy mediated the relationship between peer victimization and NSSI. Clinical implications of these findings for college counselors are discussed. 相似文献

This paper considers the nature of citizenship found in recent republican cosmopolitan work within political theory. It argues that republican cosmopolitanism, which seeks to recognise the importance of both cosmopolitan and active citizenry within global political communities, offers important insights through which the nature of global citizenship education may be understood. After identifying the central substantive tenets of republican cosmopolitanism, key issues raised by these for citizenship education are discussed. It is suggested that citizenship education can benefit conceptually from understanding and interrogating global issues from a republican cosmopolitan perspective, and that in turn recourse to republican cosmopolitan ideas raises important questions concerning the nature and focus of global aspects of the citizenship curriculum. 相似文献

The resistance against a cyclist while riding on rollers is due mainly to rolling resistance produced by the deformation of the tyre as it rolls against small diameter drums. Resistance is then combined with wheel speed to set power output. The effect of tyre pressure and cross-section on power was investigated by systematically altering the pressure (552 kPa, 690 kPa, and 827 KPa) in a 20c, 23c, 25c, and 28c tyre of the same design while riding at a wheel speed of 45 kph. Average power over 1 minute was measured with a Power Tap Hub (Tune Corporation, Cambridge, Massachusetts, USA) on five occasions. Statistical significance was evaluated at p < 0.05. Power requirements increased significantly with each reduction in tyre pressure for all tyres and pressures except the 25c between 690 and 827 kPa. The 20c tyre required significantly more power from the cyclist at each tested tyre pressure when compared to the other tyres (which were not different from each other). The differences in resistance from tyre size were not observed when ridden on the road. Additionally, a slightly different tyre design from the same manufacturer responded similarly in the 20c, but was significantly different in the 23c size. It was also observed that power requirements increased significantly when both the wheels were ridden on the rollers as compared to just the rear wheel. These results indicate that the power requirements may be significantly altered by the cyclist by adjusting tyre pressure, tyre cross-section size, tyre type, and with the number of wheels contacting the rollers. However, the magnitude of these power requirements may not be suitable for intense workouts of trained cyclists. 相似文献

Planning a new library and developing a book and journal collection for the College of Veterinary Medicine at Iowa State University are described. The Veterinary Medical Library is a self-contained unit (6,800 square feet) for print material within the Veterinary Medical Building. Seating for 140 patrons is available. The collection is designed to provide basic materials for teaching and research in veterinary and comparative medicine. Indexing and abstracting tools permit access to local, state, and national resources as well. At present the collection totals over 17,000 volumes and over 500 serial titles. A working collection of 25,000 volumes will be maintained in the Veterinary Medical Library, and the University Library will continue to function as the principal backup source. 相似文献

A random sample of 55 WRAT-R protocols, completed by nine practitioners for a metropolitan school district in the South, was analyzed for examiner errors. All nine practitioners made errors, which occurred on 95% of the protocols and averaged 3.0 errors per protocol. The most frequent errors included failures to obtain a correct ceiling or basal, and failures to record examinees' responses. Correction of the examiner errors resulted in changes in 11 standard scores, and 3 additional changes in grade equivalent scores. These results indicate that WRAT-R administration and scoring are not as objective as assumed by the test developers, and that examiner errors on this test can adversely affect diagnostic decisions. 相似文献

Judgments Regarding Appropriate Child Supervision to Prevent Injury: The Role of Environmental Risk and Child Age 总被引:13,自引:0,他引:13
Parents, social service workers, and medical personnel failed to differ in the amount of time they estimated that children of 11 differing ages should be left without adult supervision within 5 different supervision domains. More hazardous circumstances dramatically reduced the amount of time respondents said children should be left unsupervised. Amount of unsupervised time increased with age, with clear developmental cutoffs that varied by level and type of risk. When the moderate center of the distribution was examined, 3 clear areas of consensus emerged. For most domains, constant supervision was recommended for preschool children. For early elementary school children, nearly constant (0–5 min without supervision) or close (0–15 min without supervision) supervision was recommended in safer locations, with constant supervision still recommended in high-risk situations. Only with older children was there an absence of consensus regarding supervision. The implications of these results for future injury prevention research are discussed. 相似文献

Summary For the technical, sociological-psychological, and political benefits of teacher participation in evaluation to occur, new structures and policies concerning evaluation must be put into place. Teachers must be given stagewise support in developing increased involvement and control. But finally, those policy makers, evaluation program designers and researchers who plan for teacher evaluation must act to more completely include teachers in their own evaluation. A great deal of good is at stake in the opportunity to increase teacher participation in teacher evaluation. 相似文献
