ICU生命末期患者死亡质量量表的汉化及信效度评价

为了翻译并修订重症监护病房生命末期患者死亡质量量表(QODD-3.2A),形成中文版QODD-3.2A,并对其进行信效度检验,先采用Brislin翻译模式对QODD-3.2A进行翻译、回译、专家咨询、预调查后形成中文版QODD-3.2A,之后采用便利抽样方法,对湖北省两所综合医院182例死亡患者的死亡质量进行调查并评价其信效度。通过分析,中文版QODD-3.2A量表有6个维度,共24个条目,累计方差贡献率为67.47%,总量表的Cronbach'sα值为0.891,折半系数为0.801,量表水平的内容效度指数为0.94。中文版QODD-3.2A具有较好的信效度,可作为国内ICU生命末期患者死亡质量的评估工具。     

Exercise Is In! Implicit Exercise and Sedentary‐Lifestyle Bias Held by In‐Groups1

This research examined implicit exercise‐related bias between exercising groups. Participants (N = 53) completed an Implicit Association Test with neutrally valenced exerciser or couch potato exemplars. Participants who explicitly identified as exercisers had greater positive bias toward exercisers and against couch potatoes than did participants who identified as nonexercisers. Similarly, participants who reported greater exercise had significantly greater positive bias toward exercisers than did participants who reported less exercise. Our results expand on existing research on anti‐fat and exercise‐related stereotypes by providing evidence of implicit biases for exercisers and against couch potatoes among those who are already active.     

On‐again/off‐again dating relationships: How are they different from other dating relationships?

This article explores the understudied yet prevalent phenomenon of on‐again/off‐again (on‐off) dating relationships. Study 1 (N= 445 U.S. college students) showed that almost two thirds of participants had experienced an on‐off relationship. Analyses of open‐ended responses about relationship experiences showed on‐off partners were less likely to report positives (e.g., love and understanding from partners) and more likely to report negatives (e.g., communication problems, uncertainty) than partners who had not broken up and renewed. Study 2 (N= 236), employing quantitative measures, substantiated these findings and further showed a greater number of renewals was associated with greater negatives and fewer positives. Results highlight the need for further investigation regarding on‐off relationships, and theories potentially useful in explaining these relationships are discussed.     

先天易的数学基础初探——试论先天卦序与二进位制

本文从自然数及其记数法的基本慨念出发。辨析了与二进位制相关的几个容易混淆的概念,指出序数概念的引入在近代数学发展中有重要意义。作为邵雍数学学派的数学基础,先天易是数学史上第一个专门定义的序数体系,该序数体系在数学史上率先采用了二进位制记数法。先天易作为二进制序数体系这一事实在明清时期引起不同的反响,反对者认为它使易道沦落,大数学家汪莱则从P进制的角度论证它的优越性。本文最后还对近年来反对先天易与二进制有关的两种典型观点进行了剖析．指出其谬误所在。
