预应力拱支双层网壳的静力性能研究

双层曲面网壳在结构的稳定性方面较单层网壳有优越性,在一些跨度较大或支撑较弱的建筑中更多地采用双层曲面网壳结构。预应力拱支双层网壳结构体系是在综合双层网壳和预应力拱结构等优点的基础上,构思出的一种新型大跨空间结构形式。该文主要采用一算例讨论预应力拱支双层网壳结构在三种工况下的内力及变形特点等受力性能,显示出该新型杂交结构体系整体性能得到改善,具有一定的应用前景。     

基于“行为经济学理论”的旅游者行为分析

传统的旅游者行为分析方法,主要是进行定性的分析,将各个因素进行框架分析,而对旅游者行为的影响因素分析深度不够。借助行为经济学的理论和分析方法,从旅游者的心理活动角度入手,注重旅游者的心理变量分析,应用前景理论和心理账户分析旅游者行为,充分考虑了情境因素和体验因素,使得关于旅游者的行为分析更加细化和接近现实生活。     

泰山旅游需求时空分布规律及旅游者行为特征的初步研究

泰山旅游需求存在着明显的时空分布规律．调查显示．游人数量的日变化、周变化和年内变化十分显著；客源地主要分布于山东及其周边省市；旅游区内部以泰山中路和岱顶的需求强度最大。最后对旅游交通方式、旅游消费、旅客职业构成双重游率等旅游者行为特征进行了分析。     

基于SEM的农户绿色农业生产行为研究——来自新疆352个样本农户的证据

目的 农户作为生产经营的主体,农户的绿色生产行为决定着绿色农业的发展方向。此研究分析影响农户绿色农业生产意愿及行为的相关因素及路径。方法 文章基于新疆各地州的352份农户调研数据,运用结构方程模型实证分析各影响因素对农户绿色生产行为的影响程度以及各影响因素的形成机理。结果 （1）农户对绿色农业的认知、政策的引导、感知利益和绿色生产意愿与农户的绿色生产行为呈正比,感知成本则对农户绿色生产意愿和行为具有负向作用。（2）农户的绿色认知越清晰,绿色生产意愿越强烈,政府的政策补贴和推广力度越强,越能刺激农户进行绿色生产行为。（3）农户感知到花费的金钱、劳动和精力越多,则会削弱农户的绿色生产行为。结论 行为态度、主观规范、行为控制和感知利益对农户绿色生产行为均有正向作用,其中各项指标对农户绿色生产意愿和行为的影响程度各不相同,但相对而言,农户的行为态度和主观规范对绿色生产意愿的影响更为显著,感知利益对农户绿色农业生产行为影响更强。     

Optimal social security tax with myopic agents

Myopic agents lack the foresight to save for their own old age. It is generally believed that correcting myopia is a rationale for a pay-as-you-go (PAYG) pension system. This view has been supported by existing literature showing that the optimal PAYG social security tax should increase when people are more myopic. In this paper we obtain new results opposed to the traditional view. By establishing a very standard general equilibrium OLG model with myopic agents and endogenized marginal product of capital, we show that the optimal social security tax should be lower when people are more myopic. Our numerical analysis also shows that the welfare cost of the social security tax increases with people's degree of myopia. These results suggest that correcting myopia is not a clear rationale for the PAYG social security.     

Influence of Ecuadorian Homosexual Subculture in Consumption Culture: Study about Information Consumption on Twitter

Abstract

This qualitative research examines the Ecuadorian homosexual subculture and determines how gender, images, texts, and objects are referred to consumption culture. The netnography method was used to collect data from Twitter conversations. Categorization and classification of the conversations showed how the information was created, the purpose of the message, and the target audience. Results reveal common subjects in relation to news, human rights, and gender equality. Subjects were conceptualized based on the consumption of information in social, cultural, and political environments. It was concluded that images, texts, and objects included in the conversations provide significant information about the homosexual subculture consumption behavior.     

Social exchange: Empirical examination of form and focus

We investigate similarities and differences among prominent types of social exchange (psychological contract fulfillment, perceived organizational support, trust in the organization, leader-member exchange, and trust in the supervisor) and propose that two higher-order factors represent social exchanges with the organization and with the supervisor. We investigate their prediction of important employee work attitudes, citizenship behaviors, and performance. Based on data from 448 employees, empirical tests support the existence of organization- and supervisor-directed social exchanges. Tests using structural equation modeling support unique predictions of attitudinal and behavioral work outcomes.     

消费者创新性的结构测量及对创新性行为的影响

现有文献比较全面地揭示了消费者创新性与新产品创新性行为之间的多重关系,并探讨了这些关系产生的条件和机制。但绝大多数的理论和经验研究都将消费者创新性视为一个单维构念来进行操作性界定和测量,很少有研究去探索其内在结构并在此基础上检验每个维度与新产品创新性行为之间的关系。文章旨在探讨消费者创新性的结构维度并在此基础上观察不同类型的消费者创新性对创新性行为的影响。结论表明,消费者创新性是一个包括感知创新性和认知创新性的双维构念;作为整体的消费者创新性与新产品采用行为并没有显著的相关性,只有认知创新性才与新产品的采用行为正向相关,而感知创新性只与新产品的创新性信息搜寻正向相关。上述结论为消费者创新性提供了一个新的认识,也为今后学者从该角度来研究有关消费者创新性的其他问题提供了变量测量的工具,而且还为新产品的营销实践提供了新的管理启示。     

中国渐进式改革中政府行为的成本及成因分析

中国渐进式改革模式的成本是巨大的,突出地表现为由政府行为所导致。地方政府官员的寻租行为、隐蔽其他信息、地方政府间竞争造成的资源配置扭曲、宏观经济失序等负面影响的根本原因在于预算软约束、监督缺位以及经济分权和政府集权的体制。     

责任型领导对员工绿色行为的影响:道德反思的中介作用及同理心的调节作用

基于社会学习与情感事件理论视角,探讨了责任型领导对员工绿色行为的影响机制。通过对山东省、上海市多家企业317名人员的问卷调查,实证分析结果显示责任型领导显著正向影响员工绿色行为,道德反思在责任型领导与员工绿色行为之间起部分中介作用;同理心负向调节道德反思与员工绿色行为之间的关系,同理心越弱,道德反思对员工绿色行为的影响越显著;同理心还调节责任型领导通过道德反思影响员工绿色行为这一中介机制,同理心越弱,中介效应越显著。研究结果为责任型领导激发员工绿色行为提供了新的视角,对于增加组织的环保行为具有重要的现实意义。
