摘要：We consider an ad firm that acts on behalf of advertisers to execute mobile, in-app, ad campaigns. The firm commits to provide an advertiser a specified number of ad placements (impressions) on mobile apps, usually in a specified location, and within a specified time horizon. The supply for ad space arrives, in real time, in the form of bid requests from one or more mobile ad exchanges. The ad firm needs to bid on each impression in such a way that the goals of several ongoing campaigns are me...

摘要：Although facial recognition (FR) payment technology can be more convenient for customers, it is still not consistently used by many customers in retail. Using transaction data from three retail chains, we develop econometric models and an estimation strategy for examining the social presence and herding effects that affect FR payment technology use. Our key findings are as follows: (1) Customers are less likely to use FR payment technology when more customers are in line behind them, waiting a...

摘要：A pervasive, unbroached phenomenon is how once-modern systems age into unmaintainable albatrosses. We conceptualize this phenomenon from first-principles as system atrophy. We construct a trace data set from 190 million lines of evolving code in 1,354 systems spanning 25 years to corroborate it. Our middle-range theory introduces system atrophy into the conversation on information systems evolution, showing how small increments in modularity slow atrophy but lose potency with age. Atrophy even...

摘要：This paper presents methods to choose individuals to test for infection during a pandemic such as COVID-19, characterized by high contagion and presence of asymptomatic carriers. The smart-testing ideas presented here are motivated by active learning and multi-armed bandit techniques in machine learning. Our active sampling method works in conjunction with quarantine policies, can handle different objectives, and is dynamic and adaptive in the sense that it continually adapts to changes in rea...

摘要：Whereas modern medicine has enabled humans to live longer and more robust lives, recent years have seen a significant increase in chronic care costs. The prevention of threats to mobility, such as falls, freezing of gait, and others, is critical for chronic disease management. Researchers and physicians often analyze data from wearable motion sensor-based information systems (IS) to prevent falls because of their convenience, low cost, and user privacy protection. However, prior studies on fal...

摘要：Radical, terroristic organizations pose threats to business, government, and soci-ety. The ubiquity of the modern Web and its participatory architecture have enabled such groups to become full-blown online propaganda machines. Today, radicalization that eventually leads to acts of terror occurs predominantly on the Web. Radical ideologies can be spread, in many cases unchecked, by malicious actors who take advantage of the fre-quently lax surveillance apparatus of online social platforms. This...

摘要：Supply chain agility has been recognized as a key capability for firms working to achieve superior performance in uncertain business environments. Supply chain agility is challenging to achieve, however, because it requires the firm and its supply chain partners to collaborate closely yet flexibly across organizational boundaries. Extending the boundary object literature to the supply chain context, this study unveils the mechanism through which interorganizational systems (IOS), widely deploy...

摘要：Darknet markets have been used increasingly for the transaction of drugs in the last decade. The growth of illicit drug transactions on darknet markets has led enforcement agencies to invest a greater proportion of time and effort to monitor and crack down on criminal activities on darknet websites. Whereas large-scale site-shutdown efforts involving policing agencies across various countries can help in slowing down the growth of these markets, such enforcement strategies may not be sustainab...

摘要：Online communities (OCs) have become common, both in work settings and in the personal lives of individuals. Communication among members of OCs is similar in many ways to communication among members of work and nonwork teams (e.g., both synchronous and asynchronous communication are possible). Historically, knowledge repositories have been the focus of OCs, but as OCs add more synchronous communication, it is important to understand how different communication capabilities influence user commi...

摘要：We study, using three sequential field experiments, collaborative problem solving in knowledge work enabled by information technology within the context of the customer support function in a leading high-technology firm. Experiment one examines the performance change after introducing a new collaborative problem-solving process, specifically whether the use of a team of experts across departments to solve problems can help reduce problem-solving costs. In addition to the extant process of supp...
