In social psychology, emotional contagion describes the widely observed phenomenon of one person’s emotions being influenced by surrounding people’s emotions. While the overall effect is agreed upon, the underlying mechanism of the spread of emotions has seen little quantification and application to computational agents. In this paper, we explore computational models of emotional contagion by i...

During social interactions, people tend to automatically align with, or mimic their interactor's facial expressions, vocalizations, postures and other bodily states. Automatic mimicry might be implicated in empathy and affiliation and is impaired in several pathologies. Despite a growing body of literature on its phenomenology, the function and underlying mechanisms of mimicry remain poorly und...

Nosocomial tuberculosis did not receive the respect it deserved during the 198Os, for several reasons. First, tuberculosis was thought to be a disappearing disease, to the extent that a Program for Elimination of Tuberculosis was created by the Centers for Disease Control (CDC).’ Second, rather than its previous pattern as a disease of the entire population, by the 198Os, tuberculosis had becom...

Social processes play a key role in health behavior. Understanding the underlying mechanisms of such processes is important when designing health interventions with a social component. In this work, we apply a computational model of social contagion to a data set of 2,472 users of a physical activity promotion program. We compare this model’s predictions to the predictions of a simple linear mo...

In this paper we propose a factor contagion model for correlated defaults. The model covers the heterogeneous conditionally independent portfolio and the factor infectious default portfolio as special cases. The model assumes that the hazard rate processes are driven by external common factors as well as defaults of other names in the portfolio. The total hazard construction method is used to d...

We model aggregate credit losses on large portfolios of financial positions contracted with firms subject to both cyclical default correlation and direct default contagion processes. Cyclical correlation is due to the dependence of firms on common economic factors. Contagion is associated with the local interaction of firms with their business partners. We provide an explicit normal approximati...

Three experiments investigated the phenomenon of war contagion in the context of international relations, hypothesizing that past inter-(but not intra-) state war will facilitate future, unrelated interstate war. Americans showed stronger support for violent responses to new, unrelated interstate tensions after being reminded of an historical war between the U.S. and another state, as compared ...

Based on the theory of emotional contagion and goal content, this study explored the positive associations between a leader's work passion and employees' work passion. This study investigated 364 employees and their immediate leaders from China, constructed a moderated mediation model, and used SPSS-PROCESS in conjunction with the Johnson-Neyman technique to analyze the data. The results showed...

This paper investigates the abandonment of an administrative innovationcorporate venture capital (CVC) programs by information technology (IT) corporations. CVC programs are modeled upon the venture capital (VC) practices of finding, funding, and guiding entrepreneurial startups. We draw upon prior research on organizational learning and innovation diffusion to empirically examine the role of i...
