This research focused on the nature and frequency of positive emotion in a sample of Scottish and Italian young adults and is part of larger scale on-going cross-cultural studies on positive emotion, well-being and happiness. A total of 1043 positive incidents were collected from 157 students who completed diaries in the two countries. Positive incidents were frequent in the course of daily life and were triggered by a wide variety of personal, social and environmental antecedents. Although each culture had a very similar life-satisfaction rating some cultural differences in the phenomenology of positive incidents and their emotions still emerged. As hypothesised Italian and Scottish cultures differed in the domain of independence and interdependence. Italians reported more social interactions involving talking with another and intimacy with a significant other. The Scots, in contrast, reported positive feelings associated with relaxation and being alone as frequently as other social categories, thus exemplifying independence. Recording positive incidents, as they occur moment to moment deconstructs the global and retrospective study of subjective well-being and happiness and fulfills the necessity for ecologically valid research. 相似文献

The prevalence of suicidal ideation/behavior in 1983 or 1987 and its association with future mental health in 2001 were evaluated in a provincially representative sample of Canadian adolescents (n = 1,248) aged 12 to 16 years. Approximately 13.3% (95% CI = 11.5–15.3) of adolescents self‐reported suicidal ideation/behavior. Adolescent agreement with parent (κ = .07) and teacher (κ = .05) reports at baseline was low because adults identified so few subjects. In adulthood, the associations between adolescent self‐reports of suicidal behavior/ideation and major depression and other mental health indicators were explained by respondent sex and adolescent emotional problems reported in 1983/1987. Adolescents with suicidal behavior/ideation often are not recognized by their parents and teachers and may be at risk for persistent psychiatric problems attributable to coexisting mental health problems early‐on. 相似文献

Justifying intellectual property on the basis of labour is an understandably popular strategy, but there is a tension in basing some intellectual property claims on labour that has gone largely unnoticed in treatments of the subject: many forms of innovation cause people to lose their jobs, which seriously hampers the ability of those who lose work to productively use their own labour. This article shows that even under Lockean and other labour-based justifications of intellectual property rights those who claim property rights to innovations of this type have special obligations to compensate those who lose work because of their inventions. By examining the problem that such innovations create, I hope to contribute to larger debates about automation and the job losses it often brings. Lockean and other labour-based theories of intellectual property are generally taken to secure strong, noninstrumental rights to intellectual property if they are successful. So, if even these theories imply that those who profit from the innovations driving automation have special obligations to those left jobless by it, that is strong evidence that they do in fact have such obligations. 相似文献
