Abstract
Structured sanitary preparation to mass gatherings is based on the set of instructions and legal requirements which are different for different jurisdictions. In many countries special checklists are used for itemized scrutiny of the sanitary preparation to the event. Those checklists are present in...

Abstract
Crowd behaviour in emergencies has previously been explained in terms of either 'mass panic' or strength of pre-existing social bonds. The present paper reports results from a study comparing high- versus low-identification emergency mass emergency survivors to test the interlinked claims (1) that s...

Abstract
Unrelated passerine birds often join together while mobbing, a widespread antipredator behavior during which birds harass a predator. Although previous analyses concluded that mobbing could not have evolved via reciprocity, Krams and colleagues' field experiments show that birds preferentially join m...

Abstract
We recorded the flight distances of different mouflon group types in a natural population in Sardinia. The comparison of the flight distances of the groups (n groups=375, n mouflons=1303) provided evidence for the key role of lamb presence. Female groups with lambs fled at greater distances than mal...

Abstract
Three studies examined the hypothesis that collective guilt and shame have different consequences for reparation. In 2 longitudinal studies, the ingroup was nonindigenous Chileans (Study 1: N = 124/120, lag = 8 weeks; Study 2: N = 247/137, lag = 6 months), and the outgroup was Chile's largest indige...

Abstract
One of the classic research topics in adaptive behavior is the collective displacement of groups of organisms such as flocks of birds, schools of fish, herds of mammals, and crowds of people. However, most agent-based simulations of group behavior do not provide a quantitative index for determining...

Abstract
Many cases of medically unexplained physical symptoms (MUPS) have been recorded. The sufferers of a large proportion of the more recent cases believe their illness to have been caused by exposure to chemicals in the environment. The evacuation of Melbourne airport in February 2005 exemplifies a rece...

Abstract
We adopt an individual-based model for group formation and subject it to simulated predation and foraging; the haploid individuals evolve via a genetic algorithm based on their relative success under such pressure. Our work suggests that flock or herd formation is likely to be driven by predator avo...

Abstract
Children and families are now in the front line of war, conflict and terrorism as a consequence of the paradigm shift in the nature of warfare and the growth of terror as a weapon. They are as vulnerable as are adults to the traumatizing effects of violence and mass violence. Furthermore, employing...

We need to know what hooligans think in order to anticipate their actions and prevent their violent behaviors. In this paper, I propose a theory of the hooligan's conscious mind, by analyzing the thinking of a real Italian hooligan who was my patient. I will show that violent behaviors of hooligans...
