Understanding the role of consistency during web–mobile service transition: Dimensions and boundary conditions

With the advancement of mobile technologies, numerous web service providers have begun to extend their web services to the mobile context. To understand users’ mobile service adoption behaviour in the context of the web–mobile service transition, this study investigates the role of consistency between web and mobile services by proposing a typology of consistency and examining the extent to which and the boundary conditions under which consistency works. Specifically, consistency is classified into behavioural consistency (e.g., operational consistency) and object-based consistency, which includes consistency in information, system and service in terms of the information systems success model. We also contend the mediating effect of operational consistency and the interaction effect of trust in web services and operational consistency. A field survey with 235 mobile service users confirms our mediating and moderating hypotheses. The implications for theory and practice are also discussed.

基于期望确认的信息系统持续使用模型研究:一项荟萃分析

[目的/意义] 建立在期望确认理论上的信息系统持续使用模型自提出后,被广泛用于预测用户持续使用意愿的研究中,但所得结论存在着不一致甚至彼此矛盾的情况。因此,需要对模型变量关系的稳定性给出客观评价,为后续研究提供指导和参考。[方法/过程] 选择荟萃分析作为研究方法,提取108篇文献中的样本量、相关系数等数据信息,进行描述性分析,计算效应值、失效安全系数等。[结果/结论] 研究表明,模型中五组变量关系的效应值和失效安全系数均通过稳定性检验,但其中"感知有用性-持续使用意愿"感知有用性-满意度"两组变量关系的效应值和失效安全系数偏低,对此进行了原因剖析并给出建议。     

信息系统提升企业敏捷性的机制研究

信息系统应用是否能提升企业敏捷性一直未形成共识。基于IT过程观、资源观以及动态能力观等理论,构建了信息系统能力、信息系统应用能力、企业敏捷性以及企业绩效之间关系的理论模型。利用我国201家企业的有效样本,通过验证性因子分析验证了信息技术能力、企业敏捷性以及企业绩效的构成。研究结果表明信息系统应用能力是影响企业敏捷性的直接原因。信息系统能力与企业敏捷性不存在正相关关系,信息系统能力通过信息系统应用能力的中介作用提升企业敏捷性。

非英语专业本科生跨文化敏觉力调查

跨文化敏觉力被认为是成功进行跨文化交际的首要条件,而进行跨文化敏觉力培养的首要步骤便是跨文化敏觉力的调查与评估。该论文基于陈国明和Starosta关于跨文化敏觉力的理论,应用其设计的跨文化敏觉力量表,从大学文、理、工科学生中分别抽取样本来评估非英语专业大学生的跨文化敏觉力。对评估结果进行分析的基础上,作者发现了非英语专业本科学生在跨文化敏觉力的五个维度上的具体表现,并针对大学英语教学中如何提升学生的跨文化敏觉力提出了一些建议。     

The construct of information systems use benefits: Theoretical explication of its underlying dimensions and the development of a measurement scale

As a key construct for the IS success model (DeLone & McLean (1992, 2003), information systems benefits for individuals (ISBI) has received considerable attention from researchers over the years. However, much remains to be explored to develop and validate the underlying theoretical dimensions for this crucial construct. Further, a major weakness of the extant research in this area is that most reported studies have been conducted in the context of individual IS application instead of the overall IS in the organization. To fill these gaps in research, we will first present a theoretical conceptualization of the ISBI construct, and then develop and validate a measurement scale for the construct. Drawing from the ERG theory (Alderfer, 1972), Job Characteristic Theory (Hackman & Oldham, 1975, 1976) and other theoretical perspectives, we developed a theory-based TJW framework which consists of three levels: Task performance, Job interaction, and Work enrichment. The nomological validity of the scale was then successfully demonstrated by a partial test of the IS success model using the ISBI measure and a measure of the overall IS use. Finally, we demonstrated the diagnostic power of the construct through an exploratory research model which showed that, while task performance benefits have insignificant effect on satisfaction, both job interaction benefits and work enrichment effects have substantial effects on satisfaction. These study results have thus deepened our understanding on the underpinnings of IS usage behaviors and contributed to the cumulated research on IS success.     

用三维运动学模型研究行星际激波与共转高速流的相互作用

利用三维运动学模型模拟研究行星际激波与共转高速流(CHSS)的相互作用。通过改变模式输入条件中耀斑的强度及位置,研究相互作用对CHSS到达地球时间的影响,以及对激波的传播和激波形态的影响。模拟结果表明:(1)行星际激波与CHSS相互作用对彼此到达地球时间都有影响;(2)有激波比没有激波条件下的CHSS到达地球时间要早,且CHSS到达地球时间与驱动激波的耀斑的强度以及扰动源区的位置有关,耀斑的强度越大、扰动源区与CHSS前的电流片的经度距离越近,则CHSS到达地球时间也越早;(3)激波在以CHSS为背景的太阳风中传播比在没有CHSS的均匀背景场中传播得快,但激波与CHSS的相互作用对激波到达地球时间的影响远没有对CHSS到达地球时间的影响大;(4)当耀斑位于CHSS前电流片的东边时,耀斑驱动的激波与CHSS相互作用可能会使激波形态发生改变,呈双峰结构。     

基于信息系统资源的企业动态能力提升研究

在文献分析基础上,以流程融合为中介变量,构建基于信息系统(IS)资源的企业动态能力提升的研究框架。实证分析表明,动态能力具有五维度结构;IS资源中由外而内的资源和跨越的资源对动态能力有积极影响;流程融合对于由外而内的资源与动态能力间关系中起到部分中介作用,对于跨越的资源与动态能力间关系起到完全中介效应,而对由内而外的资源与动态能力间关系的不存在中介效应。企业可以通过相应IS资源的获取与积累促进动态能力的提升。     

The impact of past performance on information valuation in virtual communities: Empirical study in online stock message boards

Unlike other types of virtual communities, individuals participate in online stock message boards for their material needs rather than non-material needs (e.g., sense of belonging). They may seek and read others’ opinions to make better investment performances. The value of information in online stock message boards may vary from person to person according to their past investment experiences. However, little is known regarding how their past investment performance influences the value of others’ opinions. Therefore, our study investigates how individuals process others’ opinions on stock message boards for their investment decisions when they have different levels of past investment performance. We proposed the unique research model with two paths consisting of both online stock message board factors and individual factors to determine continuous use of online stock message boards. We conducted SEM analysis with 452 questionnaire data. The results, first, showed that message boards factors (e.g., satisfaction using others’ opinions) have a positive impact on continuous intention to use while their own satisfaction with past investment activities has a negative impact on continuous intention to use. In addition, we believe that this is one of the few papers to examine the moderating role of self-attribution bias on the effects of stock investment performance. Our results indicated that investors with strong self-attribution bias lower the usefulness of opinions when losing money while they increased confidence in their investment-related abilities when achieving a profit from investment. This study will help to support and extend the theory of IS continuance model while providing practical insights for online stock message board managers by suggesting ways to vitalize online stock message boards.
