旅游电子商务发展迅猛,互联网购物平台的虚拟性和远程性强化了消费者感知风险,它也成为影响旅游电子商务发展的重要因素之一.文章聚焦消费者感知风险,运用SPSS 19.0及AMOS 21.0软件,构建以5个维度的感知风险为自变量、购买意愿为因变量、信任为调节变量的结构方程模型,探讨变量间相关关系.结果发现:感知风险对信任的影响差异较大,仅经济风险感知与信任呈显著负相关;感知风险对购买意愿总效应皆呈负相关;信任作为中介变量存在明显的调节作用,有效地降低了感知风险对购买意愿的负向影响.  相似文献

Climate change is a complex, multifaceted problem involving various interacting systems and actors. Therefore, the intensities, locations, and timeframes of the consequences of climate change are hard to predict and cause uncertainties. Relatively little is known about how the public perceives this scientific uncertainty and how this relates to their concern about climate change. In this article, an online survey among 306 Swiss people is reported that investigated whether people differentiate between different types of uncertainty in climate change research. Also examined was the way in which the perception of uncertainty is related to people's concern about climate change, their trust in science, their knowledge about climate change, and their political attitude. The results of a principal component analysis showed that respondents differentiated between perceived ambiguity in climate research, measurement uncertainty, and uncertainty about the future impact of climate change. Using structural equation modeling, it was found that only perceived ambiguity was directly related to concern about climate change, whereas measurement uncertainty and future uncertainty were not. Trust in climate science was strongly associated with each type of uncertainty perception and was indirectly associated with concern about climate change. Also, more knowledge about climate change was related to less strong perceptions of each type of climate science uncertainty. Hence, it is suggested that to increase public concern about climate change, it may be especially important to consider the perceived ambiguity about climate research. Efforts that foster trust in climate science also appear highly worthwhile.  相似文献

Perceptions of infectious diseases are important predictors of whether people engage in disease‐specific preventive behaviors. Having accurate beliefs about a given infectious disease has been found to be a necessary condition for engaging in appropriate preventive behaviors during an infectious disease outbreak, while endorsing conspiracy beliefs can inhibit preventive behaviors. Despite their seemingly opposing natures, knowledge and conspiracy beliefs may share some of the same psychological motivations, including a relationship with perceived risk and self‐efficacy (i.e., control). The 2015–2016 Zika epidemic provided an opportunity to explore this. The current research provides some exploratory tests of this topic derived from two studies with similar measures, but different primary outcomes: one study that included knowledge of Zika as a key outcome and one that included conspiracy beliefs about Zika as a key outcome. Both studies involved cross‐sectional data collections that occurred during the same two periods of the Zika outbreak: one data collection prior to the first cases of local Zika transmission in the United States (March–May 2016) and one just after the first cases of local transmission (July–August). Using ordinal logistic and linear regression analyses of data from two time points in both studies, the authors show an increase in relationship strength between greater perceived risk and self‐efficacy with both increased knowledge and increased conspiracy beliefs after local Zika transmission in the United States. Although these results highlight that similar psychological motivations may lead to Zika knowledge and conspiracy beliefs, there was a divergence in demographic association.  相似文献

新生代农民工过于频繁的离职行为导致企业用工成本上升,同时也阻碍了农民工的城市融入进程.基于组织支持和互惠理论,采用问卷调查的方式,实证检验了组织支持感、城市融入感及互惠与新生代农民工离职意愿之间的关系与作用机制.研究结果表明,组织支持感负向影响新生代农民工的离职意愿,城市融入感在其中起到了中介作用.同时,新生代农民工的互惠倾向对城市融入感与离职意愿的关系具有强化调节作用,并进一步调节城市融入感在组织支持感与离职意愿之间的中介作用,也即新生代农民工的互惠水平越高,城市融入感的中介作用越强.文章首次测度了新生代农民工的互惠倾向,并且验证了微观企业的组织支持能够促进新生代农民工的城市融入.研究结论为用工企业更好地理解新生代农民工心理行为机制,从而建立有效的管理措施提供了理论指导,同时为寻找新生代农民工城市融入的实现路径提供了依据.  相似文献

围绕我国“农村扶贫政策在何种程度上减缓贫困”的争论性议题,从2950篇相关研究中筛选出159篇实证研究样本文献,提取531个效应值,运用Meta Analysis系统评价了改革开放以来我国财政扶贫的减贫效应及其结构和路径。采取FAT-PET-PEESE策略的计量结果显示:扶贫政策对农民收入增长和降低贫困发生率总体上具有正向作用,其中,增收效应接近中等程度,降低贫困发生率的作用则相对较弱;从结构上看,减贫力度从高到低依次为产业扶贫、教育扶贫、搬迁扶贫、社保扶贫和生态扶贫。此外,贫困人口的行为能力差异被证明是减贫效应的可能作用路径。新时期扶贫政策应保持基本的连续性,政策实施应以强化农民反贫困能力建设为核心,探索建立相对贫困治理的长效机制。  相似文献

在复杂快变的竞争环境中,中层管理者的内部创业行为对公司内部创业战略的成败至关重要.基于公司内部创业和社会认知理论,以280名在职中层管理者为样本,实证分析感知的创业环境对中层管理者内部创业行为的影响及其作用机理.研究表明,感知的创业环境对中层管理者内部创业行为有积极的影响,而创业自我效能感在感知的创业环境与中层管理者内部创业行为之间起中介作用.由此,尝试打开感知的创业环境对中层管理者内部创业行为影响机制这一“黑箱”,丰富公司内部创业行为研究,同时为企业激发中层管理者内部创业行为提供有益的启发.  相似文献

基于37家企业和1 211名员工的问卷调研数据,依据心理契约理论和工会理论,探讨了中国转型经济背景下劳动关系氛围和工会直选对员工的心理契约破裂感知和工会承诺关系的跨层次影响。研究结果表明,劳动关系氛围同工会承诺正相关;心理契约破裂感知同工会承诺负相关;心理契约破裂感知在劳动关系氛围与工会承诺的关系中起中介作用;工会直选在心理契约破裂感知和工会承诺的关系中起调节作用,即在实现工会直选的企业,员工的心理契约破裂感知同工会承诺的负相关关系较弱。此外,对研究发现进行分析,并指出对管理实践的启示。  相似文献

ABSTRACT

Are female and male trainees similar or different in their reaction to training programmes, specifically regarding their subjective task value and motivation to transfer? According to the gender similarities hypothesis, women and men are alike on most psychological variables. However, according to research in organizational behaviour, female and male employees differ on certain aspects, such as their job satisfaction and work identity. To test these two views on gender similarities and differences in the context of human resource development and training evaluation, the present study examined the extent to which gender moderated reactions to training. Based on the expectancy-value theory of motivation and self-determination theory, a web-based questionnaire was used to measure six training reactions: intrinsic value, attainment value, utility value, perceived relative cost, autonomous motivation to transfer, and controlled motivation to transfer. The results indicated that women and men differed in their ratings of attainment value but were similar for the remaining five reaction measures. These outcomes support the gender similarities hypothesis. The findings are discussed in terms of their theoretical implications for modelling gender effects in HRD research and their practical significance for promoting training effectiveness and transfer of training.  相似文献
