The efficiency of mobile media richness across different stages of online consumer behavior     

《International Journal of Information Management》2020

The popularity of mobile devices has ushered in the prosperity of mobile commerce, yet research on mobile advertising and mobile marketing remains scant. Marketing ads possessing higher media richness generally have a positive effect on consumer decision-making, because rich media conveys more information, but mobile ads with richer media imply higher costs for both the marketer and the audience. The limitations of mobile devices have further highlighted the difficulty of mobile advertising and the issue of advertising costs. Selecting which media to deliver the appropriate information is the latest research trend, but few studies have applied the media richness theory to explain mobile ads’ effect on consumer behavior. This research thus explores the impact of media richness on consumer behavior at different AISAS (attention, interest, search, action, and share) stages, adopting experimental research, convenient sampling, and online questionnaire to collect data. From a total of 424 valid questionnaires, we find that media richness has a greater influence on the three early stages of AIS while having a lower impact on the later stages of AS. This research thus suggests that firms employing mobile ads should choose high richness media for those potential customers who are at the early stage of consumer behavior (AIS). For those who at the later stage (AS), it is good enough for marketers to utilize medium richness mobile ads. Following this suggestion, marketers can place mobile ads more precisely, thus improving the likelihood of a reduction in advertising costs for both the marketer and audience. As mobile ads with high media richness are more effective for high perceived risk products, firms need to use high richness media when they are promoting high perceived risk products even when potential consumers are at the later stage of AS. This research contributes to marketers dedicated to using a mobile advertisement strategy and helps refine both online consumer behavior and the media richness theory when including the context of mobile commerce.  相似文献   

Mobile application security: Role of perceived privacy as the predictor of security perceptions     

《International Journal of Information Management》2020

Despite mobile applications being at the frontier of mobile computation technologies, security issues pose a threat to their adoption and diffusion. Recent studies suggest that security violations could be mitigated through improved security behaviors and attitudes, not just through better technologies. Existing literature on behavioral security suggests that one of the main predictors of users’ perceptions of security is their perceived privacy concerns. Using communication privacy management theory (CPM), this study examines the effects of privacy-related perceptions, such as privacy risk and the effectiveness of privacy policies, on the security perceptions of mobile app users. To empirically test the proposed theoretical model, two survey studies were conducted using mobile apps requesting less sensitive information (n = 487) and more sensitive information (n = 559). The findings show that the perceived privacy risk negatively influences the perceived security of the mobile apps; the perceived effectiveness of a privacy policy positively influences user perceptions of mobile app security; and perceived privacy awareness moderates the effect of perceived privacy risk on the perceived security of mobile apps. The results also suggest that users have different privacy-security perceptions based on the information sensitivity of the mobile apps. Theoretical and practical implications are discussed.  相似文献   

Overcoming pathological IT use: How and why IT addicts terminate their use of games and social media     

《International Journal of Information Management》2020

IT addiction scholarship indicates that pathological use of IT such as games or social media is on the rise. While pathological IT use, such as addictive behavior, can negatively affect private, social and work life, individuals displaying addictive behavior toward an IT are challenged to overcome their addiction. In this study, we aim to offer insights into how and why IT addicts stop their pathological IT use by terminating to use the IT. We interview individuals who have overcome their IT addiction to games and social media, finding that some IT addicts terminate their use of the IT without external support because they had a strong intrinsic or extrinsic motivation or because they felt stressed, frustrated or guilty. Other IT addicts required external support, contacting a therapist after unsuccessful attempts to quit or after experiencing a shocking event. This study establishes a new strand of research into ending pathological IT use and becoming an ex-user. We theorize IT addiction as part of the IT lifecycle alongside adoption, usage and discontinuation. We also offer practical insights into why some individuals can terminate pathological IT use on their own, while others require external support.  相似文献   

Digital payment and banking adoption research in Gulf countries: A systematic literature review     

《International Journal of Information Management》2020

The global spread and use of internet and mobile contributed to the development of digital payments and baking. There is a lack of research which provides comprehensive synthesis and analysis of factors affecting the use and adoption of digital banking and payment methods in GCC countries. Thus, the aim of this paper is to provide a comprehensive literature review and perform weight and meta-analysis. By reviewing 46 studies, it was found that best predictors for digital payment and banking adoption in GCC countries are trust, perceived security and perceived usefulness. Based on the extensive literature review, the conceptual of factors affecting adoption digital banking and payment methods in Gulf countries model was proposed, which will set agenda for future research. Practitioners will be able to use the findings from this study to improve adoption and quality of digital banking and payment services  相似文献

Designing a learning curriculum and technology’s role in it     

Sue Gerber  Logan Scott 《Educational technology research and development : ETR & D》2007,55(5):461-478

This paper presents a case study of the design and implementation of a master’s level research course. Factors that defined the curriculum design problem included the subject matter, a view of learning as a change in identity, and the role of technology in curriculum design. Both the design process and results of research on the implementation of the course are described. The paper concludes with a retrospective discussion of lessons learned, including parallels of (a) user-centered technology design with our final approach to curriculum design and (b) socially constructed views of technology with socially constructed views of learning.  相似文献
