This article explores the history of photography in Zuni and provides a context for the forthcoming request from Zuni religious leaders that they be allowed to exercise some control over sensitive images held by museums. This request is part of the debate over whether Native Americans should exercise some degree of control over historic photographs of their religious ceremonies. Some Zuni community members always considered photography of religious ceremonies to be inappropriate. How it happened sheds light on how Zunis incorporated the then-new technology into their traditional beliefs and social organization. Similarly, existing museum policy toward sensitive images is a result of the way photography has been incorporated into European and American legal and ethical thinking. In addition to lending weight to the contention that forthcoming requests from Native Americans are based on long-held beliefs rather than simply contemporary political expediency, history also suggests the parameters for an equitable solution to this issue.  相似文献

The purpose of this study was to determine the effects of plyometric exercise on unilateral balance performance. Nine healthy adults performed baseline measurements on the dominant limb that consisted of: a 20-s unilateral stability test on a tilt balance board, where a higher stability index represented deterioration in balance performance; isokinetic plantar flexion torque at 0.52 and 3.14 rad s(-1); muscle soreness in the calf region; and resting plantar flexion angle. Plyometric exercise consisted of 200 counter-movement jumps designed to elicit symptoms of muscle damage, after which baseline measurements were repeated at 30 min, 24, 48, and 72 h. Perceived muscle soreness of the calf region increased significantly following the plyometric exercise protocol (F(4,32) = 17.24, P < 0.01). Peak torque was significantly reduced after the plyometric exercise protocol (F(4,32) = 7.49, P < 0.05), with greater loss of force at the lower angular velocity (F(4,32) = 3.46, P < 0.05), while resting plantar flexion angle was not significantly altered compared with baseline values (P > 0.05). The stability index was significantly increased (F(4,32) = 3.10, P < 0.05) above baseline (mean 2.3, s = 0.3) at 24 h (3.3, s = 0.4), after which values recovered. These results indicate that there is a latent impairment of balance performance following a bout of plyometric exercise, which has implications for both the use of skill-based activities and for increased injury risk following high-intensity plyometric training.  相似文献

Best practice for improving strength and power through resistance strength training has been the subject of much research and subsequent conjecture. Much of the conjecture can be attributed to methodological discrepancies. The type of dynamometry used in testing, the training experience of research participants, the specific technique employed in a lift, and the methods of collection and calculation all impact on the final variables of interest. This review examines contraction force specificity by first addressing the methodological issues surrounding our interpretation of the results. Then we address the kinematics and kinetics associated with single and multiple repetitions in relation to the development of strength, power, and functional performance. This discussion provides the delimitations for analysis of subsequent training studies. Finally, recommendations are formulated with the aim of assisting assessment and training practice as well as providing directions for future research. The results of this review suggest that the enhancements in performance resulting from resistance training are context specific in experienced resistance-trained participants. Thus, specific conditioning could be required to achieve improvements in functional performance in this group.  相似文献

ABSTRACT

This paper draws upon learning from three action research projects conducted as part of a Europe-wide project exploring young people’s social and political participation. Challenging dominant discourses about what ‘counts’ as participation and what does not, the paper explores how, through the action research projects, young people engaged in knowledge democracy in ‘new democratic arenas’. Building upon experiential knowing and creating knowledge and learning through practice, the young people explored their own democratic knowledge production, communication and engagement within a context of shifting discourses of participation, democratic engagement and active citizenship. The increasing preference of young people for more informal forms of participation as lived practice reflects a shift to young people constructing their own modes of participation and ‘remaking democracy’ in their own vision and according to their own needs. By working outside of the confines of normative assumptions of democratic practice and participation, young people exercised their own ‘political’ agency in response to their own priorities, interests and concerns and, in doing so, illustrated that new forms, understandings and practices of knowledge democracy can emerge that reflect the promise of inclusive democratic societies more meaningfully.  相似文献

Nigel Carden, deputy head of Kirkleatham Hall School, Redcar, Cleveland, describes how the work of a consortium funded through the Technical and Vocational Initiative (TVEI) has complemented school-based developments, giving rise to a broader but realistic science curriculum.  相似文献

This paper presents a case study for use in the teaching of bioprocess design. Taking the production and isolation of an intracellular protein from S. cerevisae , it demonstrates how undergraduates can use a range of data to construct and then to investigate the range of process flowsheet options available for such a process duty. The paper considers the role of newer operations, such as expanded bed technology, alongside more traditional process routes. An integrated view of bioprocess design is developed to demonstrate how unit operations interact and hence enable students to determine the eventual overall process performance that is achieved.  相似文献

There is currently renewed interest in transnational education (TNE) amongst UK universities as a means of taking education to the 98% of tertiary students worldwide who are geographically immobile. In this discourse, the home universities are characterised as the dominant players, seeking strategic opportunities to commercially expand into foreign markets. This paper argues that, in contrast, there are four key stakeholders in TNE—the home university, the partner organisation, the host government and students in the host country—and a TNE partnership is shaped by their relative power and motivations. The paper finds that unless the motivations of stakeholders are broadly aligned to the form of TNE partnership, it is unlikely to succeed. It highlights the fluid nature of these motivations which change over time—often slowly, but sometimes abruptly when there is a change in university strategy or policy on the part of the host government.  相似文献

The Education Reform Act 1988 gave independence to polytechnics and the major colleges of higher education. From a position where they were the subject of tight and bureaucratic control by the maintaining local authorities, they have moved to one where responsibility for conducting their affairs in the hands of the small group of persons who constitute their governing bodies. This paper examines the composition of governing bodies in order to see the range of sizes adopted and how boards have been constituted within the permissible limits of the Act. It also touches upon some of the difficulties and ambiguities which have been created by the present legislation. A survey reveals that most institutions have decided to have larger boards which are not dissimilar to those which existed previously and few institutions have taken advantage of the flexibility of the Act and chosen to have small boards. It remains to be seem whether size and composition have any relevance to an institution's success or otherwise in the challenging years ahead.  相似文献
