3,537 men enrolling in 2007 for mandatory army recruitment procedures were assessed for the co-occurrence of risky licit substance use among risky cannabis users. Risky cannabis use was defined as at least twice weekly; risky alcohol use as 6+ drinks more than once/monthly, or more than 20 drinks per week; and risky tobacco use as daily smoking. Ninety-five percent of all risky cannabis users r...

Longstanding theory in behavioral ecology predicts that prey should evolve decreased foraging rates under high predation threat. However, an alternative perspective suggests that growth into a size refuge from gape-limited predation and the future benefits of large size can outweigh the initial survival costs of intense foraging. Here, I evaluate the relative contributions of selection from a g...

epidemiological studies and clinical findings have shown an association between trauma and dissociation; dissociative experiences are also more prevalent among select populations such as substance dependent individuals and criminal offenders. in the present non-systematic review, we explored the association between trauma, dissociation, and high-risk behaviors. we aimed to find if the presence ...

Engineered nanomaterials (ENMs) are used in a broad spectrum of consumer products. The particle size at the nano-range gives ENMs particular physicochemical properties that may lead to exceptional performance regarding parameters such as e.g. surface reactivity, conductivity, porosity, solubility, crystallinity, optical sensitivity, bio-persistence, etc. Apart from a large range of potential be...
