摘要：Computer-mediated deception threatens the security of online users' private and personal information. Previous research confirms that humans are bad lie detectors, while demonstrating that certain observable linguistic features can provide crucial cues to detect deception. We designed and conducted an experiment that creates spontaneous deception scenarios in an interactive online game environment. Logistic regression, and certain classification methodologies were applied to analyzing data col...

摘要：It is by now almost accepted as a stylized fact that offering deal promotion (such as via Groupon or LivingSocial) deteriorates local merchants' online reputations (e.g., the average of Yelp review ratings). However, in this paper we show that the stylized fact is not true in certain circumstances. We theorize that the valence and volume of prior reviews can play an important moderating role in the effect of deal promotion. Empirically, we show that restaurants with a relatively low prior aver...

摘要：Eye-tracking technology has exhibited promise for identifying deception in automated screening systems. Prior deception research using eye trackers has focused on the detection and interpretation of brief oculometric variations in response to stimuli (e.g., specific images or interview questions). However, more research is needed to understand how variations in oculometric behaviors evolve over the course of an interaction with a deception detection system. Using latent growth curve modeling, ...

摘要：Malicious insiders continue to pose a great threat to organizations. With their knowledge and access to organizational resources, malicious insiders could launch attacks more easily that result in more damaging impacts compared to outsiders. However, empirical research about malicious insiders is rare due to the unavailability of data. With few exceptions, many studies focus on a small number of cases. In order to identify common characteristics of a large number of malicious insiders, this st...

摘要：Motivated by the rise of social media platforms that achieve a fusion of content and community, we consider the role of word-of-mouth communications (WOM) structured through a network. Using a data set from YouTube, we examine how cascades of WOM interactions enhance the popularity of videos. We first estimate the impact of channel influence and other network parameters in initiating WOM communications. The probit estimation considers the selection effect in videos that are likely to be associ...

摘要：Trust underlies much of the online shopping behavior. We compare trust in online shopping in four countries: (1) the United States, a mature online market; (2) Germany; (3) China, the fastest growing online market, where consumers are plagued by counterfeits, forgeries, and spoiled or defective items; and (4) Singapore. We performed laboratory experiments in all four countries. We used three experimental treatments: (1) no assurances; (2) promises of product quality and authenticity; and (3) p...

摘要：Enterprise resource planning (ERP) software is a platform for innovation with high failure rates due to its complexity. In China, failure rates of ERP are also high, with key differences between China and Western countries in terms of development, cultural, and organizational structure. Even when Chinese firms successfully adopt ERP, many fail to assimilate ERP and consequently never experience the full benefits of the innovation. The purpose of this study is to examine the predictors of adopt...

摘要：The past few years have witnessed millions of credit/debit cards flowing through the underground economy and ultimately causing significant financial loss. Examining key underground economy sellers has both practical and academic significance for cybercrime forensics and criminology research. Drawing on social media analytics, we have developed the AZSecure text mining system for identifying and profiling key sellers. The system identifies sellers using sentiment analysis of customer reviews a...

摘要：Crowdfunding platforms offer founders the possibility to collect funding for project realization. With the advent of these platforms, the risk of fraud has risen. Fraudulent founders provide inaccurate information or pretend interest toward a project. Within this study, we propose deception detection support mechanisms to address this novel type of Internet fraud. We analyze a sample of fraudulent and nonfraudulent projects published at a leading crowdfunding platform. We examine whether the a...
