应急物资是否足量储备是影响后续救援调度的关键。现实世界的应急物资储备方式是多源的,因此多源物资的协同储备就成为应急准备阶段的关键问题。根据实地调研的数据计算出上海市某区域的交通事故的密度函数,借用需求连续随机的存储模型对该地区的最优资源存储量进行计算,发现区域内应急救援物资储备的绝对数量不足,而且多个储备源间的调度障碍很大,应急救援调度会出现严重的困难。针对该问题,使用结构方程模型,通过调查问卷的形式得出应急救援物资储备协同的影响因素。问卷数据验证了模型的有效性和拟合程度,进一步通过路径系数检验出结构方程模型整体的拟合度。研究发现:事件因素、技术因素、部门权限因素以及部门沟通因素均可以通过正向影响信息沟通共享机制进一步正向影响应急救援资源的协同储备能力。并对该地区的应急救援物资协同制度改进路径提出可行性的建议。 相似文献

利用自编的"全国研究生培养质量满意度调查"问卷,分析不同学科博士研究生在培养质量总评价及课程教学、导师指导和学术支持三方面的满意度情况。结果表明,医学门类博士研究生培养质量的总评价最高,农学门类研究生培养质量的总评价最低。医学门类博士研究生在课程教学、导师指导和学术支持三方面也获得了博士研究生的较高评价,在多个要素上明显好于其他学科。 相似文献

课堂观察的方法与工具,需要在观察前进行整体设计。只有根据观察主题与任务选择合适的方法与工具,课堂观察和观察后的评课、议课才能有的放矢。当前中小学的课堂观察准备过程必须要明确其类型,确定其原则,掌握其基本流程;这样才能进行精准、有效的研究,为直接提高课堂教学效益发挥其应有的作用。 相似文献

This paper provides a review of school leadership preparation and development in Australia through considering the requirements for becoming a principal, how leadership preparation and development occurs, and consideration of recent developments to provide an Australian standard for school leaders. Australian educators have relied mostly on a self-identification and self-managed system in which individuals decide that they want to pursue leadership opportunities and then seek out the support and experiences to help them. Support is available and provided through system, university, and service organization programmes, and the support of colleagues and senior leaders in schools. Whilst there is an extensive range of support provided by systems, universities and service organizations, there is little evidence of their impact on schools. At the school level there needs to be far greater support in identifying and developing leaders. Developments in creating a national leadership standard might lead to some type of credentialing programme that could allow individuals to benchmark their development, and ensure that preparation and support programmes are of the highest quality. An alternative view is to reinforce greater individual responsibility for leadership development and career progress, encourage schools and systems to focus less on individual leadership and more on collective leadership, and consider more innovative ways of providing leadership development. 相似文献

In recent times, a growing consensus has emerged, among researchers and policy-makers, that a well-educated, competent and adequately supported workforce is crucial for the quality of early childhood education and care (ECEC). Despite governmental initiatives aimed to enhance the professional preparation and continuing development of early years practitioners being high on the political agenda of many EU member states, very few studies are analysing professionalisation policy developments and their implications within the national contexts of ECEC. Against this background, the article describes the key features of ECEC policies in Italy and their current trends by focussing specifically on the professionalisation of early childhood practitioners working across 0–3 and 3–6 services. Drawing on the data collected from documentary sources and interviews with key informants, this paper will critically review policy discourses as well as recurring themes and tensions arising from the academic and political debate. The findings from our analysis highlight that the increasing discontinuity characterising professionalisation initiatives across the 0–3 and 3–6 sector might lead to widening the gap among professionals working in such services. The risks that are associated with this trend are, on the one side, to devalue the educational role of 0–3 services and, on the other, to produce the schoolification of educational practices in 3–6 services. In addition, our analysis identified inconsistencies between initial and continuing professional development policies, which are progressively creating a dichotomy between initial and in-service training. The consequences of this process might produce, on the long term, the fragmentation of the ECEC system across public and private not-for-profit provision with the subsequent risk of impoverishing the local culture of childhood on which the Italian ECEC system has traditionally built its strength. 相似文献

Even though there are increasing numbers of PhD students in the distance mode, our current understanding of PhD candidature at a distance is limited and incomplete. On the one end of the spectrum are accounts of unhappy and isolated doctoral students who are separated from communities of practice. At the same time, literature offers accounts of PhD students at a distance who view themselves as agential and autonomous and are happy not to get sidetracked by others. In this reflection we ask what distinguishes the conventional PhD student from one who is studying at a distance, and invite more research on self-efficacy and vicarious learning of PhD students at a distance. 相似文献

考察基于问题的学习(PBL)对非英语专业博士生国际学术交流意识的影响。前期对40名博士生导师和2008级60名非英语专业博士生进行的问卷调查结果显示:非英语专业博士生英语应用能力和"可迁移技能"差,缺乏真实的学习环境与教学语料,不利于其培养国际学术交流意识。教学实验前后针对2009级59名学生有关程序性和元认知性知识的问卷数据对比分析发现:PBL教学有助于学生获取这两方面的知识;在对英文摘要与信件写作文本进行双样本T检验分析中未见其在促进学生获得陈述性知识方面具优势。此外,采用Ant Conc软件对2009和2010级共60名接受PBL教学的学生有关课程感受的描述性写作文本进行主题词提取,总体反映出PBL教学对博士生国际学术交流意识的培养具有积极作用。 相似文献
