暴力再犯危险性评估是当今再犯危险性评估工作中的重点, 其中, 攻击性是服刑人员暴力再犯行为稳定的个体因素。对攻击性进行研究, 有助于预防和降低服刑人员在假释或出狱后的暴力再犯行为风险, 关系社会的长治久安。研究表明, 遭受儿童期逆境和携带易感基因(如MAOA-uVNTR低活性等位基因)是导致攻击行为的重要因素。但在现有的研究中, 儿童期逆境的计分方式局限于简单的线性加总, 或所依据的统计模型忽略逆境各维度之间的交互作用和非线性关系; 在服刑人员攻击性的评估中未考虑攻击性的亚类, 而且多使用自报告的量表测评, 这些问题制约了评估的有效预测力。本研究拟通过建立潜在类别模型, 分析男性服刑人员和普通成年人群在儿童期逆境上的亚类; 以实验与问卷测量结果、司法行为记录作为攻击性指标, 揭示儿童期逆境如何影响个体的主动性攻击、反应性攻击及暴力犯罪行为, 重点探讨儿童期逆境潜在类别对主动性攻击和反应性攻击的影响, 以及MAOA-uVNTR、COMT Val158Met、5-HTTLPR基因多态性在其中的调节作用。研究结果有助于找出高攻击性个体的生物遗传指标, 从而发现受儿童期逆境经历影响的易感人群, 为暴力行为的风险预测以及针对暴力攻击行为的行为矫正和相关药物设计提供理论和实证参考, 提高相关工作的效率。 相似文献

代谢综合征(metabolic syndrome,MS)的主要组分包括中心性肥胖、高血压、糖耐量异常、脂代谢紊乱,而胰岛素抵抗被认为是MS的病理生理学基础.目前,对MS的认识还存在诸多争议,主要包括MS的命名、病因机制和病理生理学基础、其各组分及其阈值的确定以及对心血管疾病的预测价值.尽管存在争议,MS概念的提出将有助于对高危人群的心脑血管疾病及糖尿病的防治. 相似文献

Bowers, Davis, and Hanley (Bowers, J. S., Davis, C. J., & Hanley, D. A. (2005). Interfering neighbours: The impact of novel word learning on the identification of visually similar words. Cognition, 97(3), B45-B54) reported that if participants were trained to type nonwords such as banara, subsequent semantic categorization responses to similar words such as banana were delayed. This was taken as direct experimental support for a process of lexical competition during word recognition. This interpretation assumes that banara has been lexicalized, which predicts that masked form priming for items such as banara-banana should be reduced or eliminated. An experiment is reported showing that the trained novel words produced the same amount of priming as untrained nonwords on both the first and the second day of training, suggesting that the interference observed by Bowers et al was not due to word-on-word competition. 相似文献

Workforce population trends have increased the numbers and kinds of culturally diverse people who work together. Researchers in organizational behavior have often examined culture through values; however, cultural values can be based on collections of people other than traditional nation states. A cultural mosaic is presented as a framework to identify demographic, geographic, and associative features underlying culture. An individual's unique collage of multiple cultural identities yields a complex picture of the cultural influences on that person. Developments in chaos and complexity theories are proposed as a theoretical base for study on the complexity of culture at the individual level. Additional developments in network theory serve as a theoretical base for cultural research at the group level. The cultural mosaic is described as a complex system with localized structures, linking cultural tiles in ordered and chaotic ways. Research propositions examining multiple cultural identities at individual and group levels are discussed. 相似文献

Personal autonomy is central to people's experiences of agency and abilities to actively take part in society. To address the challenges of supporting autonomy, we propose a functional model of autonomy, according to which the experience of agency is a function of the opportunity to determine what to do, when to act and how to act in goal-pursuit. We tested the model in three experiments where the three goal-pursuit components could be constrained by another person or an artificial intelligence (AI) agent. Results showed that removing any of the three components from one's own decisions reduced experienced agency (Study 1a and 1b) and lowered motivation to pursue goals in organisational contexts (Study 2). In comparison to the strong and robust main effects, interactions between the components and the effects of the source of restriction (human vs. AI) were negligible. Implications for personal autonomy, algorithmic decision-making and behaviour change interventions are discussed. 相似文献

Traditionally, individuals who prioritize work over other aspects of life have been lauded as ideal employees. Individuals vary in the extent to which they endorse the beliefs that work should be prioritized over other aspects of life, known as the Belief in Work Priority (BWP). Various lockdown restrictions imposed due to the COVID-19 pandemic have blurred work-family boundary, which consequently made prioritizing work over family responsibilities challenging. A repeated cross-sectional study was conducted to examine the relationship between BWP and employee wellbeing during (vs. before) the pandemic outbreak. We recruited 398 participants who were employed and resided in the U.S. Results revealed that during the pandemic, BWP and employee wellbeing showed a negative relationship through increased work-family conflict. Furthermore, such relationship was particularly strong among married employees and male employees. 相似文献

父母-青少年亲子沟通的研究 总被引:29,自引:1,他引:28
父母-青少年亲子沟通已成为家庭与青少年心理发展研究中的一个重要课题,从上个世纪70年代起,西方研究者就开始对亲子互动的内在运行机制——亲子沟通展开了研究。该文研究从亲子沟通的特点(如沟通内容、频率、主动性、沟通问题等),影响亲子沟通的因素(沟通对象、青少年年龄、家庭环境等),亲子沟通与青少年的社会适应(自尊、学业、心理健康)、问题行为(犯罪等问题行为)的关系、亲子沟通的研究方法方面进行综述,为我国开展该领域的研究提供一些借鉴。 相似文献
