Video-based and in vivo (face-to-face) contact have been shown to be effective ways to change stigmatising attitudes and behaviours. The two approaches reflect the strengths and weakness of sometimes conflicting priorities in anti-stigma programmes: broad audience v. grassroots control. Regardless of perspective, anti-stigma interventions have the greatest impact when contact is targeted, local...

Although the functional interplay between mutant and wild-type Ras in driving tumor initiation and growth has been described, a clear picture of the precise ramifications and mechanisms of this association remains elusive, sometimes with conflicting conclusions. A report in this issue of Cancer Discovery tackles this question, which may have important implications for therapeutic strategies to ...

One is therefore likely to be trustful towards information communicated by others. On the other hand, communication can be used to manipulate others.

Punishment is a potential mechanism to stabilise cooperation between self-regarding agents. Theoretical and empirical studies on the importance of a punitive reputation have yielded conflicting results. Here, we propose that a variety of factors interact to explain why a punitive reputation is sometimes beneficial and sometimes harmful. We predict that benefits are most likely to occur in force...

This article reports on an effort to explore the differences between two approaches to intuition and expertise that are often viewed as conflicting: heuristics and biases (HB) and naturalistic decision making (NDM). Starting from the obvious fact that professional intuition is sometimes marvelous and sometimes flawed, the authors attempt to map the boundary conditions that separate true intuiti...

The problem to accurately and parsimoniously characterize random series of events (RSEs) present in the Web, such as e-mail conversations or Twitter hashtags, is not trivial. Reports found in the literature reveal two apparent conflicting visions of how RSEs should be modeled. From one side, the Poissonian processes, of which consecutive events follow each other at a relatively regular time and...
