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.     

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.     

“三鹿奶粉事件”中生鲜乳收购站的产品责任分析

将初级农产品作为产品责任法中的"产品",其生产者认定为产品责任承担主体,加大对消费者的保护力度,是世界产品责任立法的发展趋势.我国应将生鲜乳等初级农产品纳入产品责任的"产品"范围之内,让缺陷初级农产品生产者对受损害的消费者直接承担产品责任,以有效遏制和防范产品质量安全事件的频发.在 "三鹿奶粉事件"中,缺陷生鲜乳的生产者--收购站应承担产品责任.在产品责任构成要件方面,应该适当降低消费者对因果关系的证明标准.     

语篇视角下隐喻的意义构建

隐喻的意义构建体现了发话人的意图,具有较高的信息性,受到语境的直接影响和支配。在受话人寻求可接受性的推理过程中,隐喻被赋予了与语境相符、与上下文衔接、使语篇连贯的意义。     

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．     

论话语音图的传递

话语参与者的共有知识和会话原则是话语意图得以有效传递的前提和保障。话语意图的传递分两步一是说者在意图的控制并指导下说出话语;二是听者在对该话语进行理解时领会说者的意图。     

Impact of job characteristics on turnover intention and the mediating effects of job satisfaction: experiences of home visiting geriatric care workers in Korea

This study investigated the effects of job characteristics on turnover intention and the mediating effects of job satisfaction. A survey of 317 Korean care workers currently providing in-home elderly care service in the city of Seoul and its suburbs was conducted. The results of multiple regressions and an analysis of mediating effects indicated that role ambiguity and workload had significant effects on turnover intention. In addition, job satisfaction had a mediating effect on the influence of role ambiguity and workload on turnover intention. Finally, theoretical and practical implications are discussed.     

Watching online videos interactively: the impact of media capabilities in Chinese Danmaku video sites

In China, the implementation of a Danmaku social media system to sustain and raise user interest in online video sites is an increasingly widespread phenomenon. Danmaku technology is used to display users’ messages in written text on the online video stream. Little is known about the effects of this form of interactive enhancement. The aim of this empirical study is to evaluate the evolving media capabilities of the Danmaku system and their effects on users’ perceptions of interactivity and their intentions to continue using Danmaku. We draw on media synchronicity theory and apply it to a stimulus-organism-response model. Using this framework, we hypothesize that the media capabilities of the Danmaku system, namely its transmission velocity, parallelism, symbol sets, rehearsability, and reprocessability, elicit increased interactivity, which influences users’ instantaneous intentions to share and to continue the use of the Danmaku system. The results showed that both users’ instantaneous intention to share and their intention to continue to use were significantly affected by the perceived interactivity. Unlike the results of previous studies, our findings showed that all five media capabilities positively affected the users’ perceptions of interactivity. The potential theoretical and practical implications of our findings are discussed.     

汉代文人五言诗的交际意图探究

汉代文人五言诗有着作者丰富的交际意图,这些交际意图是通过诗歌中的前景化设置和话语暗含表达出来的。"游子"形象的前景化设置表达了汉代文人对仕途的追求;"思妇"形象的前景化设置表达了汉代文人对爱情的渴盼。从话语暗含的角度来看,汉代文人五言诗中的思妇诗在一定程度上也是作者追求仕途的寄托之作。     

从汇率谜团到汇率决定的社会福利平价

汇率及汇率制度之争的根本在于真实汇率的确定,而众多的汇率理论及实证模型得出的结论难以统一,有的甚至背道而驰。汇率及汇率制度理论发展至今,仍然存在诸多谜团。总结汇率理论及理论、实证汇率模型的根本假设在于购买力平价、利率平价和生产力差异。从汇率形成原理和人类经济发展角度以及东西方文明的最高诉求而言,以其作为汇率及汇率制度理论的基本假设,都不甚合理。社会福利平价是我们提出的一个有关汇率及汇率制度的新的基本假设,在此基础上,可以从一个侧面更好地揭示汇率及汇率制度选择的本质,特别是关于新兴市场经济国家汇率确定及汇率制度选择的依据问题。
