Twenty-three offenders convicted of homicide or attempted murder/manslaughter, and their respective crimes, were examined to identify any common characteristics. Court documents were assessed, and the most prominent information of the offenders was that they were often single, most of them had no psychiatric diagnoses, the most frequent modus operandi was a knife or sharp weapon (although firearms resulted in more homicides), and the most common homicide typology was domestic disputes, and disputes between friends or acquaintances. Based on a cluster analysis, two profiles emerged: one with so-called traditional criminals and another profile over-represented with offenders who commit domestic crimes.  相似文献

Previous research has examined the newsworthiness of homicide victims and explored many characteristics of victims. To date, there is no research examining homeless homicide victims even though homeless individuals are more susceptible to being victims of violent crimes. This study examines the online media coverage of four homeless homicide victims murdered by a serial killer in 2012 to ascertain how housing status impacts media coverage. Specifically, this study explores through content analysis what kind of coverage homeless individuals receive and how they are portrayed. Findings suggest that housing status is a salient characteristic in the newsworthiness of victims.  相似文献

We set out to investigate the mediating roles of depression, resilience, smoking, and alcohol use, in the relationship between potentially traumatic life events and objective and subjective, physical and mental health in a single study. A face-to-face, population-based survey was conducted in Hong Kong (N = 1147). Information on health conditions and traumatic life events was obtained, and participants completed measures of subjective physical and mental health, depression, and resilience. Smoking and drinking were not significant mediators of the relationship between life events and both objective and subjective health. Depressive symptomatology was found to mediate the relationship between life threatening illness and subjective physical health, the relationship between abuse (physical and sexual) and subjective mental health, and the relationship between the death of a parent/partner and subjective mental health. Resilience was found to mediate the relationships between multiple traumatic life events and subjective physical and mental health. Our results indicate that psychological factors rather than biological are important mediators of the relationship between life events exposure and health. Our findings provide evidence that depressive symptomatology has a mediating role only in the case of specific potentially traumatic life events and that resilience is only a critical factor in the face of exposure to multiple traumatic events, rather than single events. Our results also indicate that behavioural factors, such as smoking and drinking, are not significant mediators of the relationship between life events and health.  相似文献

Previously called Secondary Traumatic Stress (STS), secondary exposure to trauma is now considered a valid DSM-5 Criterion A stressor for posttraumatic stress disorder (PTSD). Previous studies have found high rates of STS in clinicians who treat traumatically injured patients. However, little research has examined STS among Emergency Medicine (EM) physicians and advanced practice providers (APPs). The current study enrolled EM providers (N = 118) working in one of 10 hospitals to examine risk factors, protective factors, and the prevalence of STS in this understudied population. Most of the participants were physicians (72.9%), Caucasian (85.6%), and male (70.3%) with mean age of 39.7 (SD = 8.9). Overall, 12.7% of the sample screened positive for STS with clinical levels of intrusion, arousal, and avoidance symptom clusters, and 33.9% had at least one symptom cluster at clinical levels. Low resilience and a history of personal trauma were positively associated with positive STS screens and STS severity scores. Borderline significance suggested that female gender and spending ≥10% of one’s time with trauma patients could be additional risk factors. Findings suggest that resilience-building interventions may be beneficial.  相似文献

In three experiments, we investigated whether the feedback effect on the accuracy of children’s metacognitive judgments results from an improvement in monitoring processes or the use of the Anchoring-and-Adjustment heuristic. Experiment 1 revealed that adding feedback increased the accuracy of young children’s (aged 4, 6, and 8 years) memory prediction. In Experiment 2, the influence of an external anchor on children’s metacognitive judgment was established. Finally, in Experiment 3, two memory tasks that differed in terms of difficulty were administered. Participants were randomly assigned to an anchoring (high/low/no anchor) and a feedback (feedback/no feedback) condition. Results demonstrated that children in the feedback condition adjusted their predictions toward the feedback, regardless of the task’s difficulty. These findings are consistent with the hypothesis that external information provided by feedback is used as an anchor for judgment. This interpretation is strengthened by the correlation found between the two scores computed to assess participants’ susceptibility to anchoring and feedback effects, which indicates that children who are more sensitive to the anchoring effect are also more sensitive to the feedback effect.  相似文献

Topological relations such as inside, outside, or intersection are ubiquitous to our spatial thinking. Here, we examined how people reason deductively with topological relations between points, lines, and circles in geometric diagrams. We hypothesized in particular that a counterexample search generally underlies this type of reasoning. We first verified that educated adults without specific math training were able to produce correct diagrammatic representations contained in the premisses of an inference. Our first experiment then revealed that subjects who correctly judged an inference as invalid almost always produced a counterexample to support their answer. Noticeably, even if the counterexample always bore a certain level of similarity to the initial diagram, we observed that an object was more likely to be varied between the two drawings if it was present in the conclusion of the inference. Experiments 2 and 3 then directly probed counterexample search. While participants were asked to evaluate a conclusion on the basis of a given diagram and some premisses, we modulated the difficulty of reaching a counterexample from the diagram. Our results indicate that both decreasing the counterexample density and increasing the counterexample distance impaired reasoning performance. Taken together, our results suggest that a search procedure for counterexamples, which proceeds object-wise, could underlie diagram-based geometric reasoning. Transposing points, lines, and circles to our spatial environment, the present study may ultimately provide insights on how humans reason about topological relations between positions, paths, and regions.  相似文献
