Investigation on transformation process of trip mode choice for planned special events

This paper aims to provide a decision-making method for the transportation management strategies in guiding the transformation of trip mode choice during planned special events. The Expo 2010 Shanghai is taken as an example, and a structural equation model is employed to analyze the dynamic mechanism of trip mode choice behavior and the effectiveness of the transportation management measures at different stages. Based on the difference between the objective-oriented stated preference （SP） survey results and the objectives, together with the feedback from the previous stage survey, some adjustments on the transportation management measures are made in the next stage of the planning process until the objectives are eventually achieved. The results indicate that the adjustments on transportation management measures at different stages can effectively raise the transit share to 88.6%. Nonlocal visitors are inclined to choose nonstop modes of transportation and the companion attributes have the most significant effects on the trip mode choices of visitors. The research method is proved to be an effective way to support the decision making process of transportation management measures during planned special events in the future.

男性产业工人抑郁症状影响因素研究

目的 基于结构式方程模型评价分析男性产业工人人格特质、生活事件与抑郁症状的相关性,识别抑郁症状高危因素.方法 对首钢迁安公司工人分层随机整群抽样,通过生活事件量表（LES）、大五人格简表（NEO-FFI）以及流调用抑郁自评量表（CES-D）进行评价;应用最大似然法估计结构式方程模型参数,通过修正指数确定最终模型.结果 本研究中抑郁症状（CES-D≥16分）检出率为41.05％,神经质、外向性、宜人性以及负性生活事件对抑郁症状有显著预测作用（r=0.356、-0.304、-0.135、0.227）;正性与负性生活事件、神经质与外向性、外向性与责任感、神经质与宜人性共变关系显著,相关系数分别为0.614、-0.469、0.432、-0.402,抑郁症状测量模型中情绪症状、躯体症状及人际关系症状因素载荷分别为0.779、0.678、0.464.结论 男性产业工人抑郁症状发生与神经质、外向性、宜人性以及负性生活事件有关,相关部门应当采取措施对高危工人进行疏导和干预,加强抑郁症的预防.
