The training of information personnel at the middle level in Africa is discussed. The data were derived from the latest issues of the prospectuses of the library schools at the University of Ibadan and Botswana as well as a questionnaire designed to ascertain the characteristics of the trainees in both institutions. The study reveals that the curricula of both schools extend beyond preparing trainees for the techniques and processes of a library. The trainees in both schools have sufficient educational background and library/information work experience to enable them to manage the many one-man libraries scattered all over Africa effectively, after undergoing the diploma training. It is recommended that an amalgam of the curricula of both schools can be made the standard curriculum for any institution involved in a training programme for information personnel at this level.  相似文献

The author claims that neoliberal discourse plays “hide and seek” with the state, which appears at the same time absent and present, negated, and necessitated. In order to test its limits, the paper historicizes such discourse by engaging with the Italian case. More specifically, this study examines the most representative figure of Italian neoliberalism, former prime minister and media tycoon, Silvio Berlusconi, and his ambiguous relationship with the state. Drawing on Marx and Gramsci's conceptualization of the state, the paper sheds light on the Italian context as well as the more general characteristics of the neoliberal state.  相似文献

This paper presents a comparative analysis of the structure of national higher education networks in six European countries using interlinking data. We show that national HE systems display a common core–periphery structure, which we explain by the lasting reputational differences in science, as well as the process of expansion and integration of HE systems. Furthermore, we demonstrate that centrality in national networks (coreness) is associated with organizational characteristics, reflecting that interlinking is motivated by access to resources and the status of the organizations concerned, and that national policies impact network structures by influencing the level of inequality in the distribution of resources and status. Finally, we show that, as an outcome of the core–periphery structure, the strength of ties between two HEIs is largely determined by their individual coreness, while the impact of distance is too small-scale to alter the network structure generated by organizational attributes.  相似文献

This article presents in summary a selection of the work conducted by OECD in the field of technology and education, which has been an on-going focus of OECD work since the 1980s. Recently, much of this has been under the heading of ‘New Millennium Learners’, but it has also included the widening of student achievement surveys towards digital literacy; reviews of e-learning in higher education, surveys on Open Education Resources (OER); technology as a source of innovation; and analyses of the digital resources market and educational technology patents. The article proposes the more holistic focus on ‘learning environments’ through which to analyse the very diverse ways in which technology can be integrated into education and as a design framework. This is drawn from a report of the OECD Innovative Learning Environments (ILE) project to be published in 2013, itself based on 40 case studies from different countries and regions. It suggests that contemporary learning environments should be: i) Innovating the ‘pedagogical core’; ii) Engaging the ‘Design/Redesign Leadership Circle’; iii) Widening connections and capacity through partnerships; and iv) Promoting 21st century effectiveness (based on the principles derived from the 2010 ILE learning research review). The article then applies this framework to show how technology shapes learning environments in many different ways. The article questions over-reliance on individuals navigating successfully to access non-formal learning opportunities and rejects the argument that learning institutions should simply adapt more adequately to available technologies. Instead, technology should be fully exploited in well-designed learning environments.  相似文献

Improved understanding of mobility performance in wheelchair basketball is required to increase game performance. The aim of this study was to quantify the wheelchair-athlete activities of players in different field positions and of different playing standard during wheelchair basketball matches. From video analysis, absolute and relative duration and frequency of wheelchair movements and athlete control options were examined in 27 national standard and 29 international standard players during entire wheelchair basketball matches. Between-group factorial analysis of variances identified that national players drove more forward (42.6 ± 6.8 vs. 35.4 ± 3.7%; effect size Cohen’s d (ES) = 1.48) and started more often driving forward (33.9 ± 2.6 vs. 31.8 ± 2.8; ES = 0.77) during a match while the mean activity duration for a single driving forward activity was longer (4.3 ± 0.9 vs. 3.7 ± 0.6 s; ES = 0.75) than for international players. Furthermore, national players performed fewer rotational movements (21.8 ± 4.0 vs. 28.9 ± 7.8%; ES = –1.30) and started less often with the rotational movements (35.0 ± 3.6 vs. 40.5 ± 5.5; ES = –1.21) while the mean activity duration for a single rotation activity was shorter (2.1 ± 0.3 vs. 2.3 ± 0.3 s; ES = –0.67) than for international players. Differences in mobility performance among guard, forward and centre players were minimal. The results should help wheelchair basketball coaches specify wheelchair-handling training techniques and means to optimise wheelchair-athlete configurations.  相似文献

The aim of the current study was twofold: (1) to validate the use of action sport cameras for quantifying focus of visual attention in sailing and (2) to apply this method to examine whether an external focus of attention is associated with better performance in upwind sailing. To test the validity of this novel quantification method, we first calculated the agreement between gaze location measures and head orientation measures in 13 sailors sailing upwind during training regattas using a head mounted eye tracker. The results confirmed that for measuring visual focus of attention in upwind sailing, the agreement for the two measures was high (intraclass correlation coefficient (ICC) = 0.97) and the 95% limits of agreement were acceptable (between ?8.0% and 14.6%). In a next step, we quantified the focus of visual attention in sailing upwind as fast as possible by means of an action sport camera. We captured sailing performance, operationalised as boat speed in the direction of the wind, and environmental conditions using a GPS, compass and wind meter. Four trials, each lasting 1 min, were analysed for 15 sailors each, resulting in a total of 30 upwind speed trials on port tack and 30 upwind speed trials on starboard tack. The results revealed that in sailing – within constantly changing environments – the focus of attention is not a significant predictor for better upwind sailing performances. This implicates that neither external nor internal foci of attention was per se correlated with better performances. Rather, relatively large interindividual differences seem to indicate that different visual attention strategies can lead to similar performance outcomes.  相似文献

This article investigates experimentally the effects of sensational content on viewing choices and satisfaction in television consumption. The authors found that the presence of verbal violence in one program causes subjects to watch more of that program. However, subjects do not experience higher satisfaction with the program. In addition, they report lower satisfaction with the overall viewing experience. These findings are robust to the use of different program types for the experimental manipulation. Overall, the results pose a challenge to the use of audience figures as a measure of enjoyment or satisfaction.  相似文献
