医务人员言语偏误的伦理评介

通过具体临床言语资料的分析,发现医惠交际中存在着言语信息失量、言语态度失衡、言语策略失慎和言伴信息失却等问题.医务人员对患者缺乏必要的人文关怀和伦理照应是问题产生的关键.加强医务人员的言语伦理修养,是对传统医学伦理的尊重,也是新形势下促进医惠关系和谐发展的一项重要举措.     

调节匹配对期望与绩效关系的影响

以往研究发现了调节定向、调节期望与绩效的关系。本研究基于调节匹配理论,以149名大学生为被试、通过与个体长期调节定向相一致或不一致的任务框架(收获/无收获vs无损失/损失)操作调节匹配性,进一步研究了调节匹配对期望与绩效关系的影响。结果显示,调节匹配会进一步加强以往研究中发现的调节定向对期望和绩效关系的调节模式,不匹配会起到削弱作用。当促进定向占主导的个体完成强调有无收获的任务时,高期望对绩效的促进作用显著高于完成强调有无损失的任务;而当预防定向占主导的个体完成强调有无损失的任务时,低期望对绩效的促进作用显著高于完成强调有无收益的任务。     

Pathways Between Marriage and Parenting for Wives and Husbands: The Role of Coparenting

As family systems research has expanded, so have investigations into how marital partners coparent together. Although coparenting research has increasingly found support for the influential role of coparenting on both marital relationships and parenting practices, coparenting has traditionally been investigated as part of an indirect system which begins with marital health, is mediated by coparenting processes, and then culminates in each partner's parenting. The field has not tested how this traditional model compares with the equally plausible alternative model, in which coparenting simultaneously predicts both marital relationships and parenting practices. Furthermore, statistical and practical limitations have typically resulted in only one parent being analyzed in these models. This study used model-fitting analyses to include both wives and husbands in a test of these two alternative models of the role of coparenting in the family system. Our data suggested that both the traditional indirect model (marital health to coparenting to parenting practices), and the alternative predictor model where coparenting alliance directly and simultaneously predicts marital health and parenting practices, fit for both spouses. This suggests that dynamic and multiple roles may be played by coparenting in the overall family system, and raises important practical implications for family clinicians.     

CTPI和CTA在椎底动脉系统TIA诊断中的互补性

研究CT灌注成像(CTPI)和CT血管造影(CTA)对椎底动脉系统短暂性脑缺血发作(TIA)的诊断价值.采用64排螺旋CT对30例患者进行常规CT、CT灌注成像和CT血管造影检查.30例CT平扫无责任病灶.CT灌注成像正常14例,异常16例.CTA正常4例,异常26例,CT灌注成像和CT血管造影联合应用有利于椎底动脉系统短暂性脑缺血发作的诊断和治疗方案的选择.
