Environmental losses suffered by commercial and residential real estate owners are becoming more frequent and severe due to evolving regulatory regimes and the changing global climate. This article reviews the nature of environmental risk, specifically within the context of a changing climate, and proposes the large-scale installation of green infrastructure as both a business opportunity for insurers and a responsible approach. 相似文献

Scientific opinions differ whether the use of stimulants causes deterioration in driving skills. In 1857 of 8709 cases of driving under the influence of drugs, amphetamine-like drugs (amphetamine, methamphetamine, and methylendioxyamphetamine) were present either alone or together with other licit or illicit drugs. In 338 cases, amphetamines were the only psychoactive substance group in plasma at mean, median, and highest concentrations of 0.18, 0.12, and 1.05 mg/L, respectively. A widespread opinion is that after the consumption of amphetamines, centrally stimulating effects with corresponding consequences on safe driving are expected. In contrast, many cases were observed that rather suggested an influence of centrally sedating substances when considering the psycho-physical conditions. Relations between concentration and effect could not be established. The apparent sedation is probably the consequence of sleep deprivation during an amphetamine binge and the after-effects of the drug. 相似文献

Questionnaire data from 376 undergraduates (mean age=19.3 years) were used to test a model describing interrelationships among deidealization, relatedness, autonomy, and insecurity in late adolescents' relationships with their parents. As expected, deidealization predicted greater autonomy and less relatedness (i.e., more disengagement), greater disengagement predicted greater insecurity, and greater insecurity predicted less autonomy. However, disengagement from parents proved to be a double-edged sword in that it was linked not only to insecurity, but also to feelings of greater separateness and self-directedness in relation, to parents. Additional analyses identified significant associations between the adolescent/parent relationship variables and the adolescents' psychological health and ego identity status.Received her Ph.D. from Yale University.
