Hierarchical linear modeling was used to examine the relationships between social capital (at the individual, the neighborhood, and the regional levels) and adolescents' fear of crime, while controlling for the main individual (sociodemographics, television viewing, and bullying victimization), neighborhood (neighborhood size and aggregated victimization), and regional (crime rate and level of urbanization) variables. Data were analyzed using a three‐level model based on 22,639 15.7‐year‐old (SD = 0.67) students nested within 1081 neighborhoods and 19 Italian regions. The findings revealed that individual and contextual measures of social capital, modeled at the individual, neighborhood, and regional levels simultaneously, showed negative associations with adolescents' fear of crime. Males and participants with higher family affluence were less likely to feel fear of crime, whereas victimization, both at the individual and neighborhood levels, had a positive association with fear of crime. Strengths, limitations, and potential applications of the study are discussed. 相似文献

The purpose of this study was to explore the idea that there are dark side personality differences in the profiles of people at different levels in organizations. This study replicates and extends existing leadership research by focusing on self‐defeating behavioral tendencies. A Danish consultancy provided data on 264 adults based on assessment reports. This paper explored linear and quadratic relationships between personality and de facto job level. More senior managers scored high on Cluster B/Moving Against Others scales of Bold, Colorful and Imaginative, and low on Cautious and Dutiful. These Danish data are compared to data from Great Britain and New Zealand which show very similar findings. Practice should take into account that dark side personality traits associated with an assertive, sometimes hostile, interpersonal orientation, predict leadership level up to a point. 相似文献

Current research in molecular epidemiology uses biomarkers to model the different disease phases from environmental exposure, to early clinical changes, to development of disease. The hope is to get a better understanding of the causal impact of a number of pollutants and chemicals on several diseases, including cancer and allergies. In a recent paper Russo and Williamson (Med Stud, 2012) address the question of what evidential elements enter the conceptualisation and modelling stages of this type of biomarkers research. Recent research in causality has examined Ned Hall’s distinction between two concepts of causality: production and dependence (Hall in Causation and counterfactuals. MIT Press, Cambridge, pp 225–276, 2004). In another recent paper, Illari (Philos Technol, p 20, 2011b) examined the relatively under-explored production approach to causality, arguing that at least one job of an account of causal production is to illuminate our inferential practices concerning causal linking. Illari argued that an informational account solves existing problems with traditional accounts. This paper follows up this previous work by investigating the nature of the causal links established in biomarkers research. We argue that traditional accounts of productive causality are unable to provide a sensible account of the nature of the causal link in biomarkers research, while an informational account is very promising. 相似文献

While anxiety is typically thought to increase distractibility, this notion mostly derives from studies using emotionally loaded distractors presented in the same modality as the target stimuli and tasks involving crosstalk interference. We examined whether pathological anxiety might also increase distractibility for emotionally neutral irrelevant sounds presented prior to target stimuli in a task where these stimuli do not compete for selection. Patients with anxiety and control participants categorized visual digits preceded by task-irrelevant sounds that changed on rare trials (auditory deviance). Both groups exhibited an equivalent increase in response times following a deviant sound but patients showed a reduction of response accuracy, which was entirely due to an increase in response omissions. We conclude that the involuntary capture of attention by unexpected stimuli may, in patients with anxiety, result in a temporary suspension of cognitive activity. 相似文献

Over thirty years ago Krugman (1965) claimed that learning of advertising messages was much more like an Ebbinghaus nonsense syllable memory task than an exercise in rhetoric. If anything, he seems even more right today in a media environment that continues to become more cluttered. In this article, we investigate the role that memory plays in the development of beliefs within this context and focus on the formation of beliefs that develop with little intention or opportunity to learn. Following on previous work, we investigate the effect of repetition‐induced increases in belief for advertising claims that are hierarchically related: a superordinate general benefit claim (e.g., security of a lock) and multiple subordinate feature claims (e.g., pick resistant and professional installation required). We find that beliefs in feature claims increase monotonically with number of exposures, although at a diminishing marginal rate. We find no evidence of horizontal spillover of repetition‐induced increases in belief from one subordinate feature claim to another. However, we find a substantial amount of vertical spillover of repetition‐induced increases in belief from individual subordinate feature claims to the superordinate general benefit. A dual mediation analysis suggests that the vertical spillover comes from both an increase in familiarity of the general benefit and greater belief in the set of subordinate feature claims. 相似文献

In three experiments, 4‐, 5‐, 6‐ and 8‐year‐olds and adults were asked to draw hierarchical letter and geometric forms from memory. Across the experiments, the number of elements comprising the hierarchical models was systematically varied. For each drawing of a hierarchical form, the quality of the participant’s reproduction of global and local level information was evaluated separately. Results showed that young children demonstrated significant analytic competence. However, the data also suggested that changes in stimulus density were more disruptive, in specific ways, to 4‐ and 5‐year‐old children’s processing than to that of the older children and adults. 相似文献

We argue that the health sciences make causal claims on the basis of evidence both of physical mechanisms, and of probabilistic dependencies. Consequently, an analysis of causality solely in terms of physical mechanisms or solely in terms of probabilistic relationships, does not do justice to the causal claims of these sciences. Yet there seems to be a single relation of cause in these sciences—pluralism about causality will not do either. Instead, we maintain, the health sciences require a theory of causality that unifies its mechanistic and probabilistic aspects. We argue that the epistemic theory of causality provides the required unification. 相似文献
