认知诊断中的Q矩阵及其作用

Q矩阵作为连接认知和测量的桥梁,在认知诊断中起重要作用。本文梳理了应用Q矩阵解决认知诊断相关问题的理论与方法。首先整理Q矩阵的相关概念、算法、性质及其在认知诊断中的作用;并根据Q矩阵可计算理论构念效度、可以构成格等,指出Q矩阵是特殊的关联矩阵;接着介绍Q矩阵理论研究方面的几个近期发展;并对Q矩阵未来的应用研究作出展望。期望本文能为测量工作者更灵活地利用Q矩阵提供参考和帮助。     

In focus. Life after BioethicsLine: a reply to Joyce Plaza

The recent closure and removal of BioethicsLine led many researchers to wonder where to turn for their research needs. Joyce Plaza wrote that the closure is a mistake. In this essay I maintain, contra Plaza, that due to its cross-disciplinary nature researchers can find bioethics literature in other databases. In developing the search strategy the researcher needs to consider what the problem is about. If the researcher has a philosophical approach in mind, a wise choice would be to use Philosopher's Index; a legal approach suggests using Academic Universe, Westlaw, Lexis or legal databases freely available through state and federal websites. Further, in so far as the National Library of Medicine is integrating citations in BioethicsLine into the NLM Gateway databases (PubMed and LOCATORplus) I point out suggestions on using the latter databases effectively. There is a wealth of information readily available and researchers have much to learn by trying the alternatives.     

Self-supporting personality and psychological symptoms: The mediating effects of stress and social support

This study examined relations among self-supporting personality, stress, social support, and psychological symptoms in a sample of 782 Chinese undergraduate students using the Self-Supporting Personality Scale for Adolescent Students (SSPS-AS), Adolescent Self-Rating Life Event Checklist (ASLEC), Multidimensional Scale of Perceived Social Support (MPSSS), and Symptoms Check List 90 (SCL-90). As predicted, results from cross-sectional structural equation analyses suggested that stress and social support mediate the relationship between four self-supporting personality traits and psychological symptoms; an alternative stress-moderation model was not supported.     

Marital Problems and Marital Satisfaction Among Brazilian Couples

As the practice of marriage and family therapy is spreading across the world, it is important for knowledge regarding marital processes and patterns to expand to countries outside of North America and Europe. This study examined common marital problems faced by Brazilian couples. The sample consisted of 80 married couples living in Porto Alegre, Brazil. Results showed that money, children, jealousy, and sex were common problems faced by Brazilian couples. There were few gender differences found. Sex and alcohol had a significant impact on marital satisfaction of wives, and sex had a significant impact on marital satisfaction of husbands.     

道德自我调节对亲社会行为和违规行为的影响

本文通过两个研究探讨道德自我调节对亲社会行为和违规行为的影响。研究一中,被试随机分为三组,分别抄写“正性特质词语”“负性特质词语”或“中性词语”,并回忆自己所经历的与关键词有关的事情。启动完成后,考察其捐助行为。结果发现,正性特质启动组被试愿意捐助的数目显著高于负性特质和中性词语启动组。研究二用同样的方法改变被试的道德自我知觉,然后对被试的作弊行为进行了考察。结果发现,正性特质启动组的作弊严重程度显著低于中性词语启动组,负性特质启动组的作弊发生率和作弊严重程度显著低于中性词语启动组。本研究表明,道德自我调节过程不一定遵循负反馈机制：虽然“道德净化效应”在本研究中得到了部分验证,但是我们的实验结果不符合“道德许可效应”的预期。     

冠状动脉造影及介入治疗选择的临床决策

冠心病是当今威胁人类健康的重要疾病之一,其主要病理生理机制是冠状动脉狭窄或闭塞所致的心肌缺血或坏死.目前,冠状动脉造影(CAG)及经皮冠状动脉介入治疗(PCI)已广泛应用于冠心病的确诊和治疗,众多患者为之受益.然而,我们也发现其中部分患者可能不必要接受CAG,或CAG后可能不必要或不宜接受PCI.鉴于此类技术的有创性、风险性、高费用等因素,同时为避免过度诊疗,充分评估已知冠心病介入治疗的选择及未知胸痛或其他情况CAG的选择,正确进行临床决策十分必要.     

Perceived Parental Protectiveness Promotes Positive Friend Influence

Friend influence over prosocial behaviour and delinquent behaviour was examined as a function of relative parental protectiveness in a community sample of Lithuanian high school students (M = 16.5 years old). Participants completed self‐reports describing commitment to personal values, delinquent behaviours, prosocial behaviours, and perceived parental protectiveness. Mutual friends (158 male dyads, 241 female dyads) were identified from peer nominations. Distinguishable dyad Actor–Partner Interdependence Model analyses illustrate how parenting promotes positive peer influence. The results indicate that friend influence is greatest in the context of protective parenting: Adolescents who perceived more parental protectiveness were positively influenced by the strength of their friend's personal values, whereas adolescents who perceived less parental protectiveness were not.

Dying to Believe or Dying to Belief? Systemic Violence and the Possibilities of Constructive Nihilism in Pastoral Theology

This article draws upon pragmatist and post-metaphysical philosophy and theology to understand the potential dangers that inhere in metaphysical and foundationalist thought, giving particular attention to the way certain anthropological understandings contribute to the perpetration of systemic violence. The effects of systemic violence are taken into account as a pastoral concern at the intersection of politics and pastoral care. The article offers a proposal of “constructive nihilism” as a potential way forward toward the reduction of systemic violence.     

自我批评与青少年自伤:有调节的中介效应

采用情绪调节量表、自我批评量表、心理痛苦量表和自伤行为量表对914名中学生进行测查,从中筛选出311名有自伤行为的青少年进行统计分析,探讨自我批评与青少年自伤行为的关系,并在此基础上提出一个有调节的中介模型,考察心理痛苦的中介作用和认知重评的调节作用。结果表明:(1)在控制了性别和是否独生子女的影响后,自我批评可以显著正向预测青少年的自伤行为,心理痛苦在二者之间起中介作用;(2)自我批评通过心理痛苦对自伤行为的间接效应受到认知重评的调节,认知重评可以减弱自我批评对自伤行为的间接影响。
