针对中美联合教育项目留学生在美国大学校园生活和学习的适应状况,本研究从多维的角度调查项目学生在学业方面遇到的主要问题及学生的性别、年龄、教育层次、在美时间等因素对学生文化学习适应的影响;调查项目留学生在美大学校园文化生活满意度与其对美国的态度、思乡、文化休克之间的关系,以期为国内大学发展与之相关的出国留学生适应辅助项目提供支持,为留学生出国前的语言培训、学业和心理准备提供帮助。 相似文献

The integration of climate change adaptation considerations into management of the coast poses major challenges for decision makers. This article reports on a case study undertaken in Christchurch Bay, UK, examining local capacity for strategic response to climate risks, with a particular focus on issues surrounding coastal defense. Drawing primarily on qualitative research with local and regional stakeholders, the analysis identifies fundamental disjunctures between generic concerns over climate change and the adaptive capacity of local management institutions. Closely linked with issues of scale, the problems highlighted here are likely to have broad and continuing relevance for future coastal management elsewhere. 相似文献

Abstract Marine and coastal zone policy represents a collaboration of people managing and people managed. This paper takes a holistic stance in suggesting that marine communities are viewed properly as networks of focused interest groups, policymakers, professionals, and publics. The interplay between culture and marine and coastal policy is appropriately one topic of applied social research. Seven ethnographic studies in this domain are introduced in this theme issue and help us to understand sociocultural processes and institutions bearing on marine affairs. 相似文献

基于瞳孔面积变动的公路隧道明暗适应时间 总被引:1,自引:0,他引:1
公路隧道进出口照度剧烈变化,容易造成驾驶员明暗视觉适应困难,也是导致交通事故的重要原因,因此驾驶员明暗适应时间的确定是解析隧道视觉安全的基础问题.以26条典型公路隧道为例,利用IViewX HED Laptop眼动仪系统,对公路隧道路段驾驶员的视觉适应性进行了试验研究.根据大量试验数据建立了隧道进出口瞳孔面积及面积变化临界速度定量关系.在此基础上利用瞳孔面积速度/瞳孔面积临界速度比率κ来评价隧道路段视觉负荷,并建立了基于λ值的视觉明暗适应时间指标,最终得到隧道长度与视觉明暗适应时间的定量关系.对于中长隧道,暗适应时间一般不超过23 s,明适应时间不超过13s. 相似文献

This paper develops a model, based on Bayesian beliefs networks, for representing mental maps and cognitive learning into micro-simulation models of activity-travel behavior. Mental maps can be used to address the problem that choice sets in models of travel demand are often ad hoc specified. The theory underlying the model is discussed, a specification is derived and numerical simulation is used to illustrate the properties of the model. 相似文献

人非共板断面通过机动车与非机动车高差进行分离,减少机非碰撞的交通事故;避免非机动车对机动车通行的影响,但也不可避免地带来人非冲突予盾增加,非机动车频繁起伏,舒适性下降等问题;结合道路红线宽度、机动车、非机动车交通组织等因素,研究人非共板断面在路段及交叉口范围的交通模式,从而分析总结人非共板断面的适用范围. 相似文献
