摘要：The bursts and multiplicity of Internet advertising have made multichannel attribution an immediate challenge for marketing practitioners. Existing attribution models predominantly focus on analyzing consumers' conversion paths with respect to one focal firm while largely overlooking the impact of their interactions with competing firms, leading to biased estimates of advertising effectiveness. We address this problem by developing an integrated individual-level choice model that considers con...

摘要：The proliferation of smartphones and other mobile devices has led to numerous companies investing significant resources in developing mobile applications, in every imaginable domain. As apps proliferate, understanding the impact of app adoption on key outcomes of interest and linking this understanding to the underlying mechanisms that drive these results is imperative. In this paper, we explore the changes in user behavior induced by adoption of a mobile application, in terms of engagement an...

摘要：Legacy information systems consume a large portion of information technology budgets and often impose serious limitations on organizations 'flexibility and innovation. Despite the extensive literature on how organizations adopt and use new IS, we know little about how organizations discontinue their legacy IS. Current studies suggest some actions and events to cease mechanisms such as legitimization, learning, and routinization that give continuity to the systems. However, we do not know when ...

摘要：All knowing is material. The challenge for Information Systems research is to specify how knowing is material by drawing on theoretical characterizations of the digital. Synthetic knowing is knowing informed by theorizing digital materiality. We focus on two defining qualities: liquefaction (unhinging digital representations from physical objects, qualities, or processes) and open-endedness (extendable and generative). The Internet of Things (IoT) is crucial because sensors are vehicles of liq...

摘要：Online hacker forums offer a prominent avenue for sharing hacking knowledge. Using a field dataset culled from multiple sources, we find that online discussion of distributed denial of service (DDOS) attacks in hackforums.net decreases the number of DDOS-attack victims. A 1% increase in discussion decreases DDOS attacks by 0.032% to 0.122%. This means that two DDOS-attack posts per day could reduce the number of victims by 700 to 2,600 per day. We find that discussion topics with similar keywo...

摘要：Grounded in the aging and complexity literature, this experimental study investigated the moderating role of individuals' cognitive age on the impact of recommendation agent (RA) comprehensiveness (i.e., amount of detail involved in using an RA) on users' perceptions regarding RA complexity and RA usefulness. An experiment involving 140 online shoppers was conducted to understand the experiences of cognitively younger and older adults while using low or high comprehensiveness RAs designed for ...

摘要：This research examines hospital digital advantage, defined as a hospital's technological edge relative to its competitors across a composite of technologies supporting the hospital's various functions and processes. Drawing on Bourdieu 's forms of capital and the logic of digital options, we develop an integrative conceptual framework to identify and organize antecedents of digital advantage, which can translate to hospital performance through the creation of digital options. Focusing on the a...

摘要：Society's growing dependence on computers and information technologies has been matched by an escalation of the frequency and sophistication of cyber attacks committed by criminals operating from the Darknet. As a result, security researchers have taken an interest in scrutinizing the Darknet and other underground web communities to develop a better understanding of cybercriminals and emerging threats. However, many scholars lack the capability or expertise to operationalize Darknet research a...

摘要：Identity theft has impaired e-commerce. To combat the crime, many identity theft countermeasures (ITC) have been proposed. As investments in ITC are substantial and the benefits of such investments are intangible, companies are often hesitant to adopt such measures. This was the motivation for this study of the impact of 526 ITC adoption announcements on short- and long-term market value. The event study shows that such announcements result in positive market return of about U.S. $583 million ...

摘要：Crowdsourcing contests are contests by which organizations tap into the wisdom of crowds by outsourcing tasks to large groups of people on the Internet. In an online environment often characterized by anonymity and lack of trust, there are inherent uncertainties for participants of such contests. This study focuses on crowdsourcing contests with winner-take-all prizes. During these contests, submissions are made sequentially and contest hosts can provide public in process feedback to the submi...
