摘要：Social media communications offer valuable feedback to firms about their brands. We present a targeted approach to Twitter sentiment analysis for brands using supervised feature engineering and the dynamic architecture for artificial neural networks. The proposed approach addresses challenges associated with the unique characteristics of the Twitter language and brand-related tweet sentiment class distribution. We demonstrate its effectiveness on Twitter data sets related to two distinctive br...

摘要：Information systems (IS) integration is a critical challenge for value-creating mergers and acquisitions. Appropriate design and implementation of IS integration is typically a precondition for enabling a majority of the anticipated business benefits of a combined organization. Often, IS integration projects are subject to deficiencies (e.g., loss of the target firm's business capabilities with expedited integration) that limit value creation. Drawing on a configurational perspective, we reana...

摘要：Organizations increasingly use virtual groups for many types of work, yet little research has examined factors that make groups perform better across multiple different types of tasks. Previous research has proposed that groups, like individuals, have a general factor of collective intelligence, an ability to perform consistently across multiple types of tasks. We studied groups that used computer-mediated communication (CMC) to investigate whether collective intelligence is similar or differe...

摘要：Despite the increasing relevance of online social interactions on platforms, there is still little research on the temporal interaction dynamics between electronic word-of-mouth (eWOM, a form of opinion-based social interaction), popularity information (a form of action-based social interaction), and consumer decision making. Drawing on a panel data set of more than 23,300 crowdfunding campaigns from Indiegogo, we investigate the dynamic effects of these social interactions on consumers' fundi...

摘要：Problematic use of social networking sites (SNS) and its adverse consequences have become prevalent, yet little is known about the conceptualization and etiology of problematic use of SNS. This study draws on dual-system theory (DST), borrowed from cognitive neuroscience (also known as reflective-impulsive theory of the mind and fast and slow thinking) to investigate what drives this phenomenon. The statistical analyses of time-lagged data collected from 341 Facebook users implicate an imbalan...
