Educating the teacher educator—A Ugandan case study

Who educates teacher educators? How are teacher educators educated and prepared for their roles and tasks? This article uses a review of a two-year full-time Diploma in Teacher Education (DTE) for teacher educators in Uganda to engage with these questions. The article begins with a presentation of the Ugandan teacher education context and a literature review, focusing mainly on teacher educator knowledge, preparation, roles and tasks. It then presents the review process and discusses the main findings that emerged, exploring their implications for the education of teacher educators in Uganda and internationally. The main implications concern the critical role of teacher education pedagogy, context, teacher educator knowledge, tasks and roles, reflective practice, practitioner research, and the background, capacities and education of the educator of teacher educators.     

Hot hands,cold feet? Investigating effects of interacting constraints on place kicking performance at the 2015 Rugby Union World Cup

Place kicks in Rugby Union present valuable opportunities to score points outside the spatiotemporal dynamics of open play but are executed under varying performance constraints. We analysed effects of specific task constraints and relevant contextual factors on place kick performance in the 2015 Rugby Union World Cup. Data were collected from television broadcasts for each place kick. In addition to kick outcomes, contextual factors, including time of the kick in the match, score margin at the time of the kick, and outcome of the kicker’s previous kick, were recorded. Effects of spatial task constraints were analysed for each kick, using distance (m) and angle (°) of the kick to the goalposts. A binomial logistic regression model revealed that distance from, and angle to, the goalposts were significant predictors of place kick outcome. Furthermore, the success percentage of kickers who missed their previous kick was 7% lower than those who scored their previous kick. Place kick success percentage in the 10 minutes before half-time was 8% lower than the mean tournament success percentage, which was 75% (95% CI 71–78%). The highest kick success percentage was recorded when scores were level (83%; 95% CI 72–91%). Our data highlighted how subtle changes in task constraints and contextual factors can influence performance outcomes in elite performers in international competition. Fluctuations in place kick success suggested that individual constraints, such as thoughts, emotions and fatigue, induced during competition, could interact with perceptions to influence emergent performance behaviours.     

The interplay of cognitive and relational social capital dimensions in university-industry collaboration: Overcoming the experience barrier

The use of university-industry collaboration in the innovation process is viewed as a major driver of firm competitiveness. The organizational dynamics underlying successful external relationships, however, remain poorly understood. Using longitudinal case studies of 15 innovation projects, we examine how firms with varying degrees of experience in collaborating with universities and public research organizations rely on different social capital dimensions to achieve successful collaborations. We find that experienced firms establish external collaborations on the basis of cognitive social capital, but this basis is reinforced by relational social capital over time. Conversely, less experienced firms initially base their university collaborations on relational social capital, which is reinforced by cognitive social capital over time. Based on these findings, we theorize on the interplay of different dimensions of social capital in university-industry collaborations over time. Our study has important implications for the management of collaborative innovation projects. In particular, it provides guidance to enable less experienced firms to develop successful collaborations with university partners.

广西产业结构及第三产业结构的灰色关联分析

良好的产业结构有利于一个地区的快速发展,不断优化产业结构是促进经济又好又快发展的重要举措.广西自治区的第三产业已成为地区三次产业的领头羊,但是,第三产业在数量上的领先并不意味着对地区经济总量的影响一定最大,也不能说明三次产业的内部结构一定合理.通过对广西与长三角两省一市的三次产业对地区生产总值分析,第三产业内部各部门和第三产业以及地区生产总值之间的灰色关联分析,我们认为广西的产业结构仍需进一步调整优化,尤其是第三产业内部.     

Inter-organizational relationships and knowledge sharing through the relationship and institutional orientations in supply chains

Sharing knowledge in inter-organizational relationships is one way to enhance strategic competitiveness. It is generally agreed that the development of close relationships facilitates such sharing among partners. This paper presents a research model comprises five research hypotheses with four constructs, including relationship orientation, institutional orientation, relational risk and knowledge sharing. This study develops a conceptual model that relational risk as a mediating construct to examine the inter-relationship effects that affect knowledge sharing and these relationships. We analyze data collected from 312 of the top 1000 Taiwanese manufacturing firms in 2011 listed in Business Weekly. The results of the empirical study suggest that the role played by relationship orientation and institutional orientation is critical in ensuring the inter-organizational knowledge sharing as it mitigates the relational risk in the process. The findings of the study provide practical insights into how supply chain members should reinforce their relational and institutional view of relational governance and manage relational risks so as to improve their collaborative behaviors and in turn achieve the competitive advantage of knowledge sharing for the supply chain as a whole.     

Improved sentence retrieval using local context and sentence length

In this paper we propose improved variants of the sentence retrieval method TF–ISF (a TF–IDF or Term Frequency–Inverse Document Frequency variant for sentence retrieval). The improvement is achieved by using context consisting of neighboring sentences and at the same time promoting the retrieval of longer sentences. We thoroughly compare new modified TF–ISF methods to the TF–ISF baseline, to an earlier attempt to include context into TF–ISF named tfmix and to a language modeling based method that uses context and promoting retrieval of long sentences named 3MMPDS. Experimental results show that the TF–ISF method can be improved using local context. Results also show that the TF–ISF method can be improved by promoting the retrieval of longer sentences. Finally we show that the best results are achieved when combining both modifications. All new methods (TF–ISF variants) also show statistically significant better results than the other tested methods.
