ABSTRACTThis research explores two ongoing professional development (PD) modalities for early childhood teachers and their effect to teachers’ performance. We compare training, teacher study groups and a combination of both to a control group in the Albanian preschool context. We aimed to obtain mоrе cоmplеtе understanding оf different facеts оf thе ongoing professional development оf еarly childhооd tеachеrs and its pоtеntial impact оn program quality and children’s dеvеlоpmеnt in different еarly childhооd sеttings, especially in countries of low and middle income. This study has led to policy changes in mоrе еfficiеntly planning rеsоurcеs, not only fоr еarly childhood tеachеrs’ PD, but tо tеachеrs and оthеr practitiоnеrs in thе field as well. This research has pushed for evidence-based policy reforms in teacher professionalization and career advancement in Albania. 相似文献

The aim of the present study was to investigate loading effects on kinematic and kinetic variables among elite-weightlifters in order to identify an optimal training load to maximize power production for clean-movement. Nine elite-weightlifter (age: 24 ± 4years, body-mass: 77 ± 6.5kg, height: 176 ± 6.1cm and 1RM clean: 170 ± 5kg) performed 2 separate repetitions of the clean using 85, 90, 95% and 100%, in a randomized order, while standing on a force platform and being recorded using 3D-capture-system. Differences in kinematics (barbell displacement, velocity and acceleration) and kinetics (power, vertical ground reaction force (vGRF), rate of force development (RFD), and work) across the loads were statistically assessed. Results revealed significant load effects for the majority of the studied parameters (p < 0.01) and showed that typical bar-displacement, greatest bar-velocity and peak-power were achieved at 85 and 90% 1RM (p < 0.001). Additionally greater average power was shown for 90 and 95% (p < 0.01) and greater work and vGRF were shown for 90, 95 and 100% than 85% 1RM (p < 0.05). Load had no significant effect on peak-vGRF and peak-RFD (p > 0.05). The results of this study, suggest 90% 1RM to be the most advantageous load to train explosive-force and to enhance power-outputs while maintaining technical efficiency in elite-weightlifters. 相似文献

The use of external knowledge for innovation (i.e., inbound or outside-in open innovation) has received substantial attention in the innovation literature. However, the “human side” of open innovation is still poorly understood. We consider the role of employee characteristics with respect to predicting firm-level openness. Drawing on the human capital, learning and creativity literatures, we theorize that knowledge diversity of the firm’s employees is positively associated with employees’ ability to identify and absorb external knowledge, which aggregates to increased firm-level openness—that is, firms’ use of external knowledge in their pursuit of innovation. Based on a combination of three data sources, namely, two survey data sources and register data, we find support for our hypothesis that employees’ educational diversity is positively associated with firm-level openness. However, we find no direct association between employees’ work history diversity and firm-level openness but rather—as also hypothesized—a conditional relationship based on educational background, which implies that diverse work history only has a positive impact at higher levels of educational diversity. To reduce endogeneity concerns, we undertake a series of robustness checks. 相似文献

The aim of this article is to review the situation regarding legislation on library and information services, and in particular, the changes that have taken place over the past 20 years in French-speaking African countries. Our study concerns 24 African countries, located in North Africa (Algeria, Morocco, Tunisia), West Africa (Benin, Burkina Faso, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo), as well as East and Central Africa (Burundi, Cameroon, Central African Republic, Chad, Congo, Democratic Republic of Congo, Gabon, Rwanda), Djibouti, the Comoros, Madagascar and Seychelles.The institutions examined in this study are primarily national libraries and documentation centres. Nevertheless, we will also look at legislative decisions affecting national information systems and public and university libraries, as well as some decisions governing the practice of the librarian profession.The main changes that took place over the past two decades concern the setting up of international Francophone institutions and the support provided to information and library infrastructures in developing countries. We also note a definite improvement in documentation systems, due largely to a greater priority placed on information and the action of professionals trained in library science faculties and colleges, who continue to promote the need for adequate legislation to ensure well-performing institutions. 相似文献

The central goal of this study is to clarify to what degree former education and students’ personal characteristics (the ‘Big
Five personality characteristics’, personal orientations on learning and students’ study approach) may predict study outcome
(required credits and study continuance). Analysis of the data gathered through questionnaires of 1,471 Universities of Applied
Sciences students make clear that former Education did not come forth as a powerful predictor for Credits or Study Continuance.
Significant predictors are Conscientiousness and Ambivalence and Lack of Regulation. The higher the scores on Conscientiousness
the more credits students are bound to obtain and the more likely they will continue their education. On the other hand students
with high scores on Ambivalence and Lack of Regulation will most likely obtain fewer Credits or drop out more easily. The
question arises what these results mean for the present knowledge economy which demands an increase of inhabitants with an
advanced level of education. Finally, implications and recommendations for future research are suggested. 相似文献

We evaluate article-level metrics along two dimensions. Firstly, we analyse metrics’ ranking bias in terms of fields and time. Secondly, we evaluate their performance based on test data that consists of (1) papers that have won high-impact awards and (2) papers that have won prizes for outstanding quality. We consider different citation impact indicators and indirect ranking algorithms in combination with various normalisation approaches (mean-based, percentile-based, co-citation-based, and post hoc rescaling). We execute all experiments on two publication databases which use different field categorisation schemes (author-chosen concept categories and categories based on papers’ semantic information).In terms of bias, we find that citation counts are always less time biased but always more field biased compared to PageRank. Furthermore, rescaling paper scores by a constant number of similarly aged papers reduces time bias more effectively compared to normalising by calendar years. We also find that percentile citation scores are less field and time biased than mean-normalised citation counts.In terms of performance, we find that time-normalised metrics identify high-impact papers better shortly after their publication compared to their non-normalised variants. However, after 7 to 10 years, the non-normalised metrics perform better. A similar trend exists for the set of high-quality papers where these performance cross-over points occur after 5 to 10 years.Lastly, we also find that personalising PageRank with papers’ citation counts reduces time bias but increases field bias. Similarly, using papers’ associated journal impact factors to personalise PageRank increases its field bias. In terms of performance, PageRank should always be personalised with papers’ citation counts and time-rescaled for citation windows smaller than 7 to 10 years. 相似文献

Increasingly, innovative collaboration between industry and schools is being exploited as a way of improving the quality and relevance of education. Even though these innovations appear to have substantial benefits, often the impact proves to fade away after their implementation. A better understanding of how to sustain complex innovations seems important. Unfortunately, only a limited amount of research investigates the ‘inside’ of complex innovations. This article reports on a three-year, large-scale industry–school programme in the Dutch Leisure sector. The research, from start to finish, adopted a qualitative case study methodology with a mixed-methods approach, drawing upon social capital theory as lens to understand the dynamics of processes and effect on outcomes. Findings indicate that the social capital theory helps to unravel crucial factors of processes and outcomes. The researched innovation process depended not so much on formal project plans and objectives but largely built on the quality of social relationships at all levels. Sustaining this social capital proved crucial, while managing according to a planned change strategy appeared to be counterproductive. The outcomes show to be twofold, in terms of new knowledge and products for the organisations and of sustainable benefits for the professionals, in terms of new abilities. 相似文献
