摘要：Virtual communities continue to play a greater role in social, political, and economic interactions. However, how users value information from these communities and how that affects their behavior and future expectations is not fully understood. Stock message boards provide an excellent setting to analyze these issues given the large user base and market uncertainty. Using data from 502 investor responses from a field experiment on one of the largest message board operators in South Korea, our...

摘要：Universal access (UA) to the Internet and the associated information infrastructure has become an important economic and societal goal. However, UA initiatives tend to focus on issues such as physical access and geographical ubiquity, and they measure adoption through penetration rates. In this paper, we apply an interpretive case study approach to analyze the Philadelphia wireless initiative to provide insights into the nature of UA and extend this concept to also consider universal use (UU)....

摘要：In a social network, adoption probability refers to the probability that a social entity will adopt a product, service, or opinion in the foreseeable future. Such probabilities are central to fundamental issues in social network analysis, including the influence maximization problem. In practice, adoption probabilities have significant implications for applications ranging from social network-based target marketing to political campaigns, yet predicting adoption probabilities has not received ...

摘要：Despite the popular use of social media by consumers and marketers, empirical research investigating their economic values still lags. In this study, we integrate qualitative user-marketer interaction content data from a fan page brand community on Facebook and consumer transactions data to assemble a unique data set at the individual consumer level. We then quantify the impact of community contents from consumers (usergenerated content, i.e., UGC) and marketers (marketer-generated content, i....

摘要：Topical locality on the Web is the notion that pages tend to link to other topically similar pages and that such similarity decays rapidly with link distance. This supports meaningful Web browsing and searching by information consumers. It also allows topical Web crawlers, programs that fetch pages by following hyperlinks, to harvest topical subsets of the Web for applications such as those in vertical search and business intelligence. We show that the Web exhibits another property that we cal...

摘要：Firms nowadays are increasingly proactive in trying to strategically capitalize on consumer networks and social interactions. In this paper, we complement an emerging body of research on the engineering of word-of-mouth effects by exploring a different angle through which firms can strategically exploit the value-generation potential of the user network. Namely, we consider how software firms should optimize the strength of network effects at utility level by adjusting the level of embedded so...

摘要：The Internet has provided IS researchers with the opportunity to conduct studies with extremely large samples, frequently well over 10,000 observations. There are many advantages to large samples, but researchers using statistical inference must be aware of the p-value problem associated with them. In very large samples, p-values go quickly to zero, and solely relying on p-values can lead the researcher to claim support for results of no practical significance. In a survey of large sample IS r...

摘要：We examine how network centrality and closure, two key aspects of network structure, affect technology adoption. In doing so, we consider the content of potential information flows within the network and argue that the impact of network structure on technology adoption can be better understood by separately examining its impact from two groups of alters-current and potential adopters. We contend that increased network centrality and closure among current adopters contribute positively to adopt...
