There has been extensive research into friend-oriented and professional social networking websites, but relatively little work on passion-oriented sites designed to connect strangers around a shared passion. In this study, we extend the work on passion-oriented social networking through an examination of pet-oriented social networks. We address two questions. First, do people interacting in sem...

Historians of science have often neglected the eighteenth century because it lacks famous figureheads like Isaac Newton or Charles Darwin, yet this was a crucial period when science started to become established and gain prestige, writes Patricia Fara in a new book*. With their Enlightenment contemporaries, Carl Linnaeus in Sweden and Joseph Banks in Britain illustrate how scientific research w...

Vallerand et al. (2003) developed a dualistic model of passion, wherein two types of passion are proposed: harmonious (HP) and obsessive (OP) passion that predict adaptive and less adaptive interpersonal outcomes, respectively. In the present research, we were interested in understanding the role of passion in the quality of coach-athlete relationships. Results of Study 1, conducted with athlet...

Across five experiments, we explore how reframing a socially inappropriate emotional expression (distress) by publicly attributing it to an appropriate source (passion) can shape perceptions of, and decisions about, the person w...

The Dualistic Model of Passion (Vallerand et al., 2003) shows that people can experience a harmonious or an obsessive passion toward an activity.

Specifically, it was proposed that people with an obsessive...

In this paper we merge three datasets individual income data, patenting data, and IQ data to analyze the determinants of an individual’s probability of inventing. We find that: (i) parental income is positively associated with the probability of inventing, yet the estimated impact of parental income is greatly diminished once parental socioeconomic status, parental education, and the individual...

Based on self-determination theory(1) and the dualistic model of passion,(2) the authors hypothesized that high levels of basic psychological need satisfaction would foster harmonious passion for video play, supporting the subjective sense that play is something one wants to do. I...

A model of inventing new signals is introduced in the context sender-receiver games with reinforcement learning. If the invention parameter is set to zero, it reduces to basic Roth-Erev learning applied to acts rather than strategies, as in Argiento et. al. (2009). If every act is uniformly reinforced in every state it reduces to the Chinese Restaurant Process also known as the Hoppe-Pólya urn ...
