摘要：While information technology benefits society in numerous ways, it unfortunately also has potential to create new vulnerabilities. This special issue intends to stimulate thought and research into understanding and mitigating these vulnerabilities. We identify four mechanisms by which ubiquitous computing makes various entities (people, devices, organizations, societies, etc.) more vulnerable, including: increased visibility, enhanced cloaking, increased interconnectedness, and decreased costs...

摘要：To motivate user contributions, user-generated content sites routinely deploy incentive hierarchies, where users achieve increasingly higher statuses in the community after achieving increasingly more difficult goals. Yet the existing empirical literature remains largely unclear whether such hierarchies are indeed effective in inducing user contributions. We gather data from a large online crowd-based knowledge exchange to answer this question, and draw on goal setting and status hierarchy the...

摘要：Developing countries, such as India and China, are the fastest growing economies in the world. The successful implementation of information and communication technologies (ICTs) in these countries is likely to hinge on a set of institutional factors that are shaped by the environmental tension between two competing forces, emergent catalysts, such as new economic policies and reform programs, and traditional challenges, such as infrastructure and traditional value systems. To unearth the tempo...

摘要：Logistics outsourcing has increased with the commercialization of the Internet, implying a reduction in the corresponding transaction costs. The Internet-with its universal connectivity and open standards-radically enhanced information technology (IT) capabilities, and we hypothesize this has reduced external transaction costs relatively more than internal governance costs. Using transaction cost theory as a lens, we examine whether the commercialization of the Internet coincided with a move t...

摘要：Jump bidding, which refers to bidding above the minimum necessary, is a robust behavior that has been observed in a variety of ascending auctions in the field as well as the laboratory. However, the phenomenon has yet to be studied in combinatorial auctions, which are a type of multiobject auction that allows bidders to bid on a set of objects. Such auctions have been found to be beneficial when objects exhibit synergy, e.g., are complementary. In this paper, we explore jump bidding behavior i...

摘要：Since the advent of the AIS Grand Vision Project of ICT-enabled Bright Society (in short, Bright ICT), there has been significant excitement as well as confusion about the concept. To resolve ambiguities about the types of research that are consistent with this vision, the notions of Restorative Bright ICT Research and Enriching Bright ICT Research are defined. In addition, we propose three perspectives that can differentiate Bright ICT research from traditional research approaches to create a...

摘要：We examine the role of granular privacy controls on dynamic content-sharing activities and disclosure patterns of Facebook users based on the exogenous policy change in December 2009. Using a unique panel data set, we first conduct regression discontinuity analyses to verify a discontinuous jump in context generation activities and disclosure patterns around the time of the policy change. We next estimate unobserved effects models to assess the short-run and long-run effects of the change. Res...

摘要：System-generated alerts are ubiquitous in personal computing and, with the proliferation of mobile devices, daily activity. While these interruptions provide timely information, research shows they come at a high cost in terms of increased stress and decreased productivity. This is due to dual-task interference (DTI), a cognitive limitation in which even simple tasks cannot be simultaneously performed without significant performance loss. Although previous research has examined how DTI impacts...

摘要：Extant research has focused on the detection of fake reviews on online review platforms, motivated by the well-documented impact of customer reviews on the users' purchase decisions. The problem is typically approached from the perspective of protecting the credibility of review platforms, as well as the reputation and revenue of the reviewed firms. However, there is little examination of the vulnerability of individual businesses to fake review attacks. This study focuses on formalizing the v...
