Dijkstra算法的优化

Dijkstra算法是许多工程解决最短路径问题的理论基础,可用来找出图中指定节点到其他节点的最短距离,有着广泛的应用。文章通过分析传统Dijkstra算法的设计思想,提出该算法在实现方法上存在的一些不足之处,并从节约存储空间和提高运算效率方面对其进行了改进,并通过复杂性分析比较,得出这种改进算法的效率优于传统的Dijkstra算法。     

How do principals make sense of school leadership in Norwegian reorganised leadership teams?

A growing body of research has emphasised the importance of school leadership practice for quality improvement in schools. Yet, little attention has been paid to the investigation of how principals reshape their leadership role and leadership practices when schools reorganise the leadership team with the purpose of increasing the number of formally assigned leaders. As such, this study provides additional insight into how moments of transitions may reshape institutional logics regarding principal leadership practice. Drawing on interviews and contextual observations of five principals in lower secondary schools, framed within a distributed perspective and theory of sense-making, we address this issue by demonstrating that regulative changes influence the normative and cognitive aspects of institutions. We argue that principals re-conceptualise leadership when they move from being solo leaders to sharing leadership, and this allows for subjective interpretations. We have identified two approaches for principal leadership practice which the reorganised leadership team can provide – the exchanging information – and collaborative discussion approaches.

No room at the top? The glass wall for professional services managers in pre-1992 English universities

Pre-1992 English universities are changing the way they appoint their deputy and pro-vice-chancellors (PVCs). Traditionally, PVC posts were filled by internal secondment from within the professoriate, but these days an increasing number are appointed by means of external open competition involving advertisement and/or executive search. So has this ‘opening up’ of PVC positions created new career progression opportunities for professional services managers? Findings from a census, online survey and interviews with a range of senior university managers suggest not. Despite the PVC role becoming more managerial, those getting the jobs remain overwhelmingly career academics. Professional services managers confront a glass wall, excluded from consideration by a non-negotiable requirement for academic credibility. Aware they have little chance of getting a PVC job, they are unlikely to apply. The continued monopolisation of PVC posts by academic managers represents a form of social closure that serves to maintain their elite status.

邕剧里的壮族历史文化元素

国家级非物质文化遗产项目邕剧,虽然是汉民族创造的皮黄戏曲剧种,但长期在壮族聚居的桂西南地区流动演出,其舞台语言、音乐、化妆"行头"、剧目内容等,自然融进了壮族的历史文化元素,成为西南各民族共有的戏曲艺术,具有动人的艺术魅力。研究邕剧与壮族历史文化元素交融的现象,可为振兴民族传统文化艺术提供有益的启示。
