The technique of fire investigation is a forensic domain in which expertise and analogies play a central role. To learn how fire investigators use these analogies to support their work, we conducted an ethnographic study in a Swiss forensic police department. To propose a suitable knowledge-management strategy, we also evaluated the knowledge conservation and sharing within the department. Our results highlighted that actionable knowledge is registered mainly in the investigators’ memories of a few, very experienced, individuals. Without experience with fire-incident investigations, an agent generally requires help from a more experienced colleague, who will then use his memory to find a similar case, which can contribute to the solution of the ongoing one. The research also established that knowledge is exchanged orally during on-site investigations and that knowledge receivers are generally those who are present on the scene. Using these findings, we suggest building a case library to support the externalisation and sharing of knowledge. 相似文献

The higher prevalence of insomnia in women has been attributed to biological factors, which are less likely than cognitive and behavioural factors to play a role in perpetuating insomnia. Gender differences in perpetuating factors have not been extensively examined. This study compared men’s and women’s self-reports of factors that perpetuate insomnia; experience of symptoms, perceived severity and impact on daytime functioning; and use of strategies to manage insomnia. Data were collected at baseline, using reliable and valid measures, in a project that evaluated behavioural therapies for insomnia. The sample (N = 739) consisted of women (62.4%) and men (37.6%). Gender differences were found in: (1) perpetuating factors: men took more naps and held more unhelpful beliefs about insomnia, whereas women experienced higher pre-sleep arousal; (2) perception of insomnia severity: higher among women; (3) perceived impact of insomnia: higher fatigue among women; and (4) use of strategies (higher in women) to manage insomnia. Gender differences were of a small size but could be associated with women’s stress, expression of somatic symptoms, and interest in maintaining their own health to meet multiple role demands. 相似文献

基于两个分析性的创新:对社会事实秉持以机制为基础的理解路径和对动态交互影响的强调,作者提出了一个有关族群战争爆发的广义理论,并利用两种元机制——安全困境/螺旋模型和群体间–群体内互动——作为“元综合器”,将战争的影响因素与冲突行为的直接驱动力联系起来,对散布在现有文献中的众多因素和机制加以综合,形成了一个更具整合性且动态的族群战争理论。该理论不但整合了既有文献中已经识别的众多因素和机制,而且揭示了先前被隐藏或被忽视的因素、互动和机制,由此指明未来在这些方向的探究将是硕果累累。 相似文献

Many adolescents living in contexts characterized by adversity achieve positive outcomes. We adopt a protection–risk conceptual framework to examine resilience (academic achievement, civic participation, and avoidance of risk behaviors) among 1,722 never-married 12–19 year olds living in two Kenyan urban slums. We find stronger associations between explanatory factors and resilience among older (15–19 years) than younger (12–14 years) adolescents. Models for prosocial behavior and models for antisocial behavior emerge as key predictors of resilience. Further accumulation of evidence on risk and protective factors is needed to inform interventions to promote positive outcomes among youth situated in an ecology of adversity. 相似文献

Although forensic examiners operate in a stressful environment, there is a lack of understanding about workplace stress and feedback. These organizational and human factors can potentially impact forensic science judgments. In this study, 150 practicing forensic examiners from one laboratory were surveyed about their experiences of workplace stress, and the explicit and implicit feedback they receive. Forensic examiners reported that their high stress levels originated more from workplace-related factors (management and/or supervision, backlogs, and the pressure to do many cases) than from personal related factors (family, medical, and/or financial). The findings showed that a few (8%) of the forensic examiners sometimes felt strong implicit feedback about what conclusions were expected from them and that some (14%) also strongly felt that they were more appreciated when they helped to solve a case (e.g., by reaching a “match” as opposed to an “inconclusive” conclusion). Differences were found when comparing workplace stress and feedback levels across three core forensic science fields (forensic biology, chemistry, and latent prints) and across career stages (early, mid, and late). Gaining insights into the stress factors within a workplace and explicit and implicit feedback has implications for developing policies to improve the well-being, motivation, and performance of forensic examiners. 相似文献

行政生态系统由行政系统和行政生态环境两大系统构成。从目前我国的情况看,我国行政系统和行政生态环境均存在着不和谐因素。构建和谐行政,必须以行政生态学理论为指导,树立人本理念,加强行政主体建设,改革行政体制,完善行政机制,调整行政政策,健全行政法规,优化行政生态环境。 相似文献
