感知风险对在线旅游产品购买意愿的影响分析

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.     

Social service purchasing in China: Rationale,features, and risks

As part of a broader program of market reform, China's local governments are progressing an agenda of purchasing child welfare and other social services from the nongovernment sector, primarily to expand capacity and address vast unmet need. This paper draws on current research evidence to explore the approaches to purchasing emerging in China, examining the rationale for purchasing and models of supply, competition, and regulation. While some approaches are modeled on direct service contracting, direct purchasing of social service “posts” is also used, aimed at achieving goals of professionalization alongside service expansion. Overall, the review shows purchasing is helping to rapidly expand service scale and capacity; however, regulatory strategies for managing and mitigating risks to quality and access appear lacking. This highlights the need for further scholarship aimed at developing the robust risk management strategies which are required to support high quality, sustainable provision of purchased services.     

组织支持、城市融入与新生代农民工离职:一个被调节的中介模型

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.     

Media Disaster Reporting Effects on Public Risk Perception and Response to Escalating Tornado Warnings: A Natural Experiment

Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event.     

基于TRA理论的旅游电商平台的消费者行为意愿研究

O2O模式拥有广泛的发展空间和巨大潜力。文章以旅游业中的在线订房服务作为代表，研究消费者线上预订行为，针对网站特性探析消费者在线订房意愿，为互联网行业发展提出实质性建议，同时也可为其他新兴产业发现更有价值的商业模式。以理性行为理论(TRA)作为基础架构，构建以信任为中介变量的关系模型，包括6个构面（感知规模、声誉、信任、态度、感知利益、在线订房意愿）,并提出7条假设。通过实证研究验证了各因素之间的相互作用关系，其中6条假设成立并呈现出不同程度的影响，而感知利益与在线订房意愿之间的假设不被支持。本研究为管理者吸引消费者进行在线订房提供了有效可行的管理建议，亦为学术界在未来探索消费者信任在不同类型网站中的影响提供了理论基础。     

政府向社会力量购买服务改革的制度障碍及对策

政府向社会力量购买服务不仅是推动政府职能转变的重要着力点,而且是扶持社会力量发展的重要措施。各地在推动这项改革过程中取得了很大成效,但也存在着制度设计不严密、制度衔接不顺畅等问题和障碍。将这项改革深入推进下去,需要坚持有层次地放开政府资源,加强对整个购买过程的动态管理以及建立政府购买公共服务改革同其他改革之间的联动机制等多项措施的推动。     

ECM-IS视角下移动政务APP用户持续使用意愿影响因素研究

随着“互联网+”时代的到来，移动政务APP快速发展，但也存在功能单一、满意度不高、用户持续使用意愿较低的问题，要促使其健康发展，必须重视用户的使用体验和使用意愿。本研究以ECM-IS模型理论为基础，构建了移动政务APP用户持续使用意愿影响因素模型，据此设计调查问卷并进行实证研究。研究结果显示，移动政务APP的系统质量是满足用户期望的重要因素，而用户感知对于提升用户的满意度以及促使持续使用具有重要的意义，其中，感知便利性和感知有用性的积极作用尤为明显。最后，从促使用户持续使用的角度，提出了完善移动政务APP系统功能、突出实用优势，兼顾趣味功能，以及重视用户感知、强调人文关怀等对策和建议。     

Responding to violence with guns: Mass shootings and gun acquisition

Although some sources have observed an increase in the number of gun purchases following mass shootings, empirical research investigating this pattern is limited. Appraisal Theory suggests that mass shootings contribute to fear of victimization through media exposure. Desire for self-protection is the primary reason many individuals own and purchase guns. This paper examines this link by assessing the effects of six mass shootings that took place in the 2000–2010 time period. This study examines effects for gun acquisition nationally and regionally as well as timing-specific patterns in gun acquisition following these events. Gun acquisition counts are approximated from the National Instant Criminal Background Check System (NICS). Results indicate a positive but delayed association between mass shootings and the number of NICS background checks. Implications of this finding for violence and possibilities for future research are discussed.     

Supportive organizational environment,work-life enrichment,trust and turnover intention: A national survey of PRSA membership

Based on an online survey of a national random sample of the PRSA membership (n?=?650), this study is among the first to explore public relations employees’ own turnover intention and propose three contributing factors for employers to keep top talent in PR industry: a family-supportive organizational environment; the positive, enriching impact of professional work upon practitioners’ life; and PR practitioners’ trust toward employers. Theoretical and practical implications are discussed.     

技术特征、关系结构与社会化购买行为

社会化媒体技术与社会关系网络促进了社会化商务(SC)的价值创造，如何有效利用技术与用户的关系结构是 SC 企业提高其平台购买转化率的关键． 从双重视角探索技术与关系如何影响用户购买决策，基于刺激―机体―反应框架，构建了以技术可供性和强、弱关系为刺激因素，信息诊断性和意外发现性为内在机体状态，社会化购买意向为“反应”的理论模型，探索了用户社会化购买行为的发生机制． 以具有社会化购买体验的微信用户作为研究对象，运用 SmartPLS 3.0 对模型进行了路径检验和假设分析． 研究结果发现: 技术可供性与弱关系对信息诊断性和信息意外发现性具有正向影响; 弱关系对信息意外发现性的影响作用大于强关系; 信息诊断性正向影响信息意外发现性，信息诊断性与意外发现性对社会化购买意向均有显著正向影响; 然而，强关系对信息意外发现性的影响不显著． 信息诊断性与信息意外发现性部分中介了技术可供性对社会化购买意向的影响，完全中介了弱关系对社会化购买意向的影响，信息诊断性部分中介了强关系对社会化购买意向的影响． 为进一步探究社会化购买行为提供 了理论基础和实践指导．
