Abstract The author suggests being wary of looking ahead and thinking you can track truly significant changes. It’s worth being reminded that all the new tools in the world will only enhance but won’t replace the special, even magical, experience afforded by direct contact with original works of art. 相似文献

Since the 1970s, using his world-systems analysis, Immanuel Wallerstein has developed a wide-ranging framework for the social
sciences, with potential applications for comparative educational research. In this paper we outline key aspects of Wallerstein’s
theorising, and then analyse the uptake, understandings, and applications of his analysis in the field of comparative and
international education, through a case study of the Comparative Education Review (CER) journal from 1980 to 2008. This paper examines how, and how widely, his analysis has been adopted and interpreted.
Our analysis highlights significant and—given the broader emphasis in comparative education on questions of education and
development—surprising absences in the application of this approach. We conclude by arguing for the use and development of
three critical features of his analysis in comparative work, as relevant and timely interventions in the field. 相似文献

Purpose: The objectives were to develop and validate the Coaches’ Interpersonal Style Questionnaire. The Coaches’ Interpersonal Style Questionnaire analyzes the interpersonal style adopted by coaches when implementing their strategy of supporting or thwarting athletes’ basic psychological needs. Method: In Study 1, an exploratory factor analysis was performed with 265 Spanish male athletes, between 11- and 17-years-old, to confirm the internal structure of the questionnaire. Study 2 was conducted with 430 athletes, also between 11- and 17-years-old. Both confirmatory factor analysis and exploratory structural equation modeling were used to test a set of alternative models to find the best measurement model. Results: The hierarchical exploratory structural equation modeling model showed the best fit to the data and acceptable standardized factor loadings. Concurrent validity was revealed through correlational analysis of the basic psychological need satisfaction and frustration. Conclusion: This study provides a multi-dimensional questionnaire to assess coaches’ interpersonal style perceived by athletes. 相似文献

In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to ligament sprains or carpal and forearm bone fractures. Wrist protectors are worn by snowboarders in an effort to reduce injury risk, by decreasing peak impact forces and limiting wrist extension to prevent hyperextension during falls. There is no international standard or universally accepted performance specification that snowboarding wrist protectors should conform to, resulting in an inability to judge which designs offer the best protection. This study investigated how surrogate arm design affected the stiffness of wrist protectors during quasi-static mechanical testing. Three surrogate arms with increasing design complexity were used to test three wrist protectors. The results show that surrogate design does influence the stiffness of snowboarding wrist protectors. Given that the surrogate does influence protector performance, it is recommended that a standard surrogate design is established for research and product testing. 相似文献

Strength training with isometric contractions produces large but highly angle-specific adaptations. To contrast the contractile mode of isometric versus dynamic training, but diminish the strong angle specificity effect, we compared the strength gains produced by isometric training at four joint angles with conventional dynamic training. Thirty-three recreationally active healthy males aged 18?–?30 years completed 9 weeks of strength training of the quadriceps muscle group three times per week. An intra-individual design was adopted: one leg performed purely isometric training at each of four joint angles (isometrically trained leg); the other leg performed conventional dynamic training, lifting and lowering (dynamically trained leg). Both legs trained at similar relative loads for the same duration. The quadriceps strength of each leg was measured isometrically (at four angles) and isokinetically (at three velocities) pre and post training. After 9 weeks of training, the increase in isokinetic strength was similar in both legs (pooled data from three velocities: dynamically trained leg, 10.7%; isometrically trained leg, 10.5%). Isometric strength increases were significantly greater for the isometrically trained leg (pooled data from four angles: dynamically trained leg, 13.1%; isometrically trained leg, 18.0%). This may have been due to the greater absolute torque involved with isometric training or a residual angle specificity effect despite the isometric training being divided over four angles. 相似文献

This study examines the relationships between information and communication technologies (ICT) usage, the benefits a company derives from membership in a rural business cluster, and the success of rural companies. Analysis of 333 rural businesses located in northern lower Michigan showed a strong relationship between (a) ICT adoption and benefits derived from the membership in business clusters, (b) ICT adoption and self-reported business success, and (c) benefits derived from business clusters and business success. Although analysis indicates that these relationships may be industry specific, results suggest that ICT adoption by rural enterprises may have advantages for the region's social capital and business success and may help reduce the digital divide experienced in rural communities. 相似文献

This paper briefly summarizes the initial development of a computer-supported collaborative learning environment and evaluates its effects in relation to the productivity of CSCL groups. The design of the SIDE-VIEW system is driven by the social identity approach to understanding group behaviour and is premised upon the need to establish congruity between the self-definition of group members and their collaborative learning tasks. We begin by outlining the rationale for the system in relation to productivity and the emergence of team players within collaborative learning groups. We then describe aspects of the design that are intended to enhance both, and report on a field trial of the initial prototype on international groups of higher education students. The preliminary results of the field study indicate that aspects of the design encourage the emergence and influence of team players within groups, with consequential improvements to the quality of the group output. The role of team players in CSCL groups is contrasted with that of group leaders. 相似文献
