When a threat looms large in people’s minds, they may seek protective measures that could mitigate the negative outcomes associated with this threat. Paradoxically, the possession of such protective measures may, in turn, inspire a sense of safety and reduce the perceived probability of the very threat that had originally triggered their acquisition. Thus, reminding people that they possess a m...

Individuals who experience stereotype threat - the pressure resulting from social comparisons that are perceived as unfavourable - show performance decrements across a wide range of tasks. One account of this effect is that the cognitive pressure triggered by such threat drains the same cognitive (or working-memory) resources that are implicated in the respective task. The present study investi...

In a distributed multi-user environment, the security policy must not only specify legitimate user privileges but also aid in the detection of the abuse of the privileges and adapt to perceived system threat conditions. This paper advocates extending authorization policy evaluation mechanisms with a means for generating audit data allowing immediate notification of suspicious application level ...

In North America and Europe, deer (Cervidae)–vehicle collisions (DVCs) are common and result not only in injury and death to the animals involved, but also human injury and property damage. Given that most DVCs occur during crepuscular periods, we questioned whether the perceived threat to deer posed by vehicle approach could be enhanced. We hypothesized that a vehicle-based lighting system tha...

UNLABELLED We previously demonstrated that male mice display significantly reduced pain behavior on the acetic acid abdominal constriction test when confined in close proximity to a stranger male mouse. We show here the testosterone-dependence (via castration and testosterone propionate replacement) of this phenomenon, likely a form of (social) stress-induced analgesia. However, when similar ma...

We draw on data from a national RDD telephone sample of 1549 adult Americans conducted between October 15, 2001 and March 2, 2002 to explore the impact of a need for security on support for national security policies in the aftermath of the 911 terrorist attacks. In past research, an external threat has been assumed to have uniform impact on an affected population, a claim that has met with gro...

Nature is rich with many different examples of the cohesive motion of animals. Previous attempts to model collective motion have primarily focused on group behaviours of identical individuals. In contrast, we put our emphasis on modelling the contributions of different individual-level characteristics within such groups by using stochastic asynchronous updating of individual positions and orien...

BACKGROUND Health communications often present graphic, threat-based representations of the potential consequences of health-risk behaviours. These 'threat appeals' feature prominently in public health campaigns, but their use is controversial, with studies investigating their efficacy reporting inconsistent, and often negative, findings. This research examined the impact of a threat-based road...

From a clinical viewpoint, graft rejection is one of the greatest threats faced by an organ transplant recipient (OTR). We propose a middle-range theory (MRT) of Perceived Threat of the Risk of Graft Rejection (PTRGR) as a contribution to the practice of transplant nursing. It could also apply to the detection of risky protective behavior, that is, isolation, avoidance, or non-adherence. The pr...
