The contribution of Arab universities to the public good is being greatly compromised by the political and economic instability of the Arab Spring. To understand the role Arabian universities are playing in the public sphere and their ability to contribute to the public good, we interviewed 74 professors from 14 countries. Analysis of the faculty interviews yielded four major challenges: motivation and rewards for conducting research, security and safety issues, lack of a research infrastructure, and the challenges of international recognition. Our findings suggest universities should focus on the two most critical issues over which they have some control: securing safety for the faculty and creating an effective research infrastructure.  相似文献

面对世界经济的深刻变革,文化产业的勃兴已引起全世界高度关注.大力发展文化产业对我国的极端重要性,要求我们必须尽快建立健全文化产业统计制度.文章围绕建立健全我国文化产业统计制度这一主题,提出了我国文化产业统计的目标、要求以及建立文化产业统计指标体系应遵循的基本原则,具体构筑了我国文化产业统计指标体系,重点构建了测度文化产业科学发展状况统计指标子体系(一系列指数),特别是借鉴引进国际做法设置了"人文发展指数",并指出了完善我国文化产业统计应把握的几个辨证关系.  相似文献

The effects of test stimulus range on generalization gradients in humans were assessed for discriminations between faces that varied in brightness, faces that varied in orientation in the picture plane, and morphed faces. In Experiment 1, significant range effects, predicted by adaptation level theory, occurred when faces varied along the brightness or orientation dimension, but not for morphed faces. Changing the difficulty of discrimination of both training and test stimuli for Experiment 2 produced range effects in morphed faces. Experiment 3 explored training and testing stimulus factors as determinants of range effects in morphed faces. The results suggest that sufficiently biased testing ranges create shifts in response distributions (generalization gradients), and this may be amplified by using relatively difficult discriminations between training stimuli.  相似文献

This paper provides new empirical evidence on primary pupils’ views on school attendance in Wales at Key Stage 2. The research was conducted as part of the specific evidence commissioned by the Welsh Assembly Government (WAG) for the National Behaviour and Attendance Review (NBAR) in Wales which was chaired by the lead author. The findings indicate that nearly every child and young person who participated in the specially convened focus groups, in practically every setting, had a good awareness of the benefits of attending school regularly. They were all acutely aware of the potential consequences of non‐attendance both within their current setting and as it could potentially affect their later chances in life. They also understood the law regarding school attendance. They were clear about the attendance regulations within their own school settings. They were however, particularly concerned about bullying in all its forms, the use of supply teachers and “boring” teaching styles. Rewards for good attendance were generally appreciated. The implications of the findings are considered. This paper is the first of its kind to be undertaken in Wales and in the field of school attendance and opens up considerable possibilities for further research.  相似文献

It has become increasingly apparent, internationally, that childhood is a crucial life-stage in the formation of predispositions towards sports participation and that parents are increasingly investing in the sporting capital of their children via a process of ‘concerted cultivation’. It is surprising, therefore, that parents’ involvement in the development of their children's sporting interests has received so little attention in Norway, given that sport is a significant pastime for Norwegians and participation has been steadily increasing – among youngsters, in particular – over the past several decades. Through a qualitative case study of a combined primary and secondary school in a small Norwegian city, this study sought to add to recent explorations of the role of parents in children's sporting involvement in Norway. As expected, it was evident that sport becomes taken for granted and internalised very early on in Norwegian children's lives. Less expected was the recognition that children's nascent sporting interests were often generated by sports clubs via early years schooling and, therefore, that parents played only one (albeit very important) part in the formation of their youngsters’ early sporting habits. Thus, parents, sports clubs and early years schooling appeared to form something akin to a ‘sporting trinity’ in youngsters’ nascent sporting careers. These findings may have implications for policy-makers looking towards Norway for a ‘recipe’ for sports participation.  相似文献

Little is known about the reliability, validity and smallest detectable differences of selected kinetic and temporal variables recorded by the Zebris FDM-THQ instrumented treadmill especially during running. Twenty male participants (age = 31.9 years (±5.6), height = 1.81 m (±0.08), mass = 80.2 kg (±9.5), body mass index = 24.53 kg/m2 (±2.53)) walked (5 km/h) and ran (10 and 15 km/h) on an instrumented treadmill, wearing running shoes fitted with Pedar-X insoles. A test-double retest protocol was conducted over two consecutive days. Maximal vertical force (Fmax), contact time (CT) and flight time (FT) data from 10 consecutive steps were collected. Within- and between-day reliability, smallest detectable differences (SDD) and validity (95% limits of agreement (LOA)) were calculated. ICC values for the Zebris for Fmax were acceptable (ICC ≥ 0.7) while CT and FT reliability indices were predominantly good (ICC ≥ 0.8) to excellent (ICC ≥ 0.9). The Zebris significantly underestimated Fmax when compared with the Pedar-X. The 95% LOA increased with speed. SDD ranged between 96 N and 169 N for Fmax, 0.017s and 0.055s for CT and 0.021s and 0.026s for FT. In conclusion, Zebris reliability was acceptable to excellent for the variables examined, but inferior in comparison with Pedar-X. With increased running speeds, a bias effect (underestimation) existed for the Zebris compared with Pedar-X.  相似文献
