Experimenting with a new dataset of 1.6M user comments from a Greek news portal and existing datasets of English Wikipedia comments, we show that an RNN outperforms the previous state of the art in moderation. A deep, classification-specific attention mechanism improves further the overall performance of the RNN. We also compare against a CNN and a word-list baseline, considering both fully aut...

The implementation of internal social collaboration technologies confronts corporations with new challenges. Former unidirectional information flows become multidirectional and usercontent driven networks. Prior research describes the successful implementation as a challenging management task with employees’ usage at the center of attention. Consequently, corporations need to select a moderatio...

The Great Moderation refers to the fall in U.S. output growth volatility in the mid-1980s. At the same time, the United States experienced a moderation in inflation and lower average inflation. Using annual data since 1890, we find that an earlier, 1946 moderation in output and consumption growth was comparable to that of 1984. Using quarterly data since 1947, we also isolate the 1969–83 Great ...

The Great Moderation refers to the fall in U.S. output growth volatility in the mid-1980s. At the same time, the United States experienced a moderation in inflation and lower average inflation. Using annual data since 1890, we find that an earlier 1946 moderation in output and consumption growth was comparable to that of 1984. To assess the impact of these moderations, we also isolate the 1969–...

Why did the volatility of U.S. real GDP decline by more than the volatility of final sales with the Great Moderation in the mid-1980s? One possible explanation is that firms shifted their inventory behaviour towards a greater emphasis on production smoothing. In this paper, we investigate the role of inventories in the Great Moderation by estimating an unobserved components model that identifie...

The economy of the United States was markedly less volatile in the past two to three decades than in prior periods. The nation enjoyed long economic expansions in each of the last three decades, interrupted by recessions in 1990-91 and 2001 that were mild by historical standards. While it has proven difficult to conclusively pinpoint the causes of the reduced volatility, candidates include stru...

A common approach towards the role of the moderator in Internet discussions is to see him as a filter. In this article I want to show that the moderator in government-initiated Internet discussions about public issues can be seen as a democratic intermediary, and that this role has the potential to enhance the quality of those discussions as forms of deliberative democracy. I develop a conceptu...

Customer satisfaction is generally acknowledged as a key determinant of the value a customer contributes to a firm. Following the widespread recognition that the relationship is nonlinear and possibly even asymmetric, the authors develop a framework for understanding and predicting functional differences across consumers and situations. The resultant conceptualization proposes two general categ...

OBJECTIVE This study compares moderators of initiation and maintenance of health behavior changes. METHODS Data come from a cluster-randomized, 12-month telephone counseling intervention for physical activity and diet, targeting type 2 diabetes or hypertension patients (n=434, Australia,2005-2007). Demographic and health-related characteristics, theoretical constructs, and baseline behavioral...
