正确看待新生儿包皮环切术

新生儿包皮环切术通常被认为能减少尿路感染、成人阴茎癌甚至艾滋病毒感染危险,许多国家和地区常规为新生儿行包皮环切术.但近年来许多学者从医学和伦理等角度对此提出疑问,主张慎重对待新生儿包皮环切术.     

阅读障碍儿童的语言特异性认知缺陷

以41名五六年级的阅读障碍儿童和41名正常儿童为研究对象,系统考察了语言认知能力和一般认知能力与阅读成绩之问的关系.结果发现,障碍儿童在所有的语言认知测验中显著落后于正常儿童,较高比率的儿童存在能力缺陷.而在非语言特异性的一般认知能力测验中,未发现两组存在显著差异的证据,这意味着阅读障碍儿童的认知能力缺陷主要集中在语言认知领域.     

Measuring Sexism, Racism, Sexual Prejudice, Ageism, Classism, and Religious Intolerance: The Intolerant Schema Measure

Despite similarities between sexism, racism, sexual prejudice, ageism, classism, and religious intolerance, investigators do not routinely investigate these intolerant beliefs simultaneously. The purpose of this project was to create a brief, psychometrically sound measure of intolerance reflecting these 6 constructs. Data from existing measures (Attitudes Toward Women Scale, Neosexism Scale, Modern and Old-Fashioned Racism Scale, Modern Homophobia Scale, Frabroni Scale of Ageism, Economic Beliefs Scale, and M-GRISM) and from items created by the authors were obtained from several college samples to create the Intolerant Schema Measure (ISM). Results support the internal consistency, test–retest reliability, and factor structure of the questionnaire. Expected relationships between measured concepts, social dominance, social desirability, and across key demographic groups support the validity of the instrument.     

西方指导关系的理论概述

指导关系研究是西方组织行为学界近30年来比较关注的话题,然而国内对它的介绍却非常少。作者总结了大量的国外文献,从指导关系的定义、功能、发展阶段和类型四个方面进行了详细的论述。现在西方指导关系的研究已经从理论建构转向了影响指导效果的因素上,结合国内的企业背景,文章最后提出了一些相关的研究建议     

主动性人格的研究现状与展望

近年来,越来越多的研究者与管理者开始关注员工的主动行为,主动行为能够改善组织的效率和提高竞争力。主动行为受到许多因素的影响,其中一个因素即主动性人格。主动性人格是一种稳定的主动行为倾向。许多研究表明：主动性人格与许多行为结果都有密切联系,包括工作绩效、职业生涯成功、领导能力、团队绩效、创业等。今后的研究需要探讨一些问题,如主动性人格与关系绩效、职业生涯成功新标准的关系     

分配公正、程序公正、互动公正影响效果的差异

以大学生奖学金评比为例,探讨了组织公正各维度影响效果的差异。以661名大学生为被试,采用2×2×2的完全随机设计,以情境故事法（scenarios）呈现刺激,研究了奖学金评比中分配公正、程序公正、互动公正对大学生学习投入、班级荣誉感、班级归属感、与辅导员的关系的影响。结果表明,组织公正三个维度与效果变量之间存在清晰的对应影响关系：分配公正主要影响具体、以个人为参照的效果变量;程序公正主要影响与组织有关的效果变量;互动公正主要影响与上司有关的效果变量。     

Ⅱ型糖尿病人认知功能特点

综述了近10国内外关于Ⅱ型糖尿病人认知功能特点的研究。结果表明：（1）流行病学筛查因天花板效应难以发现认知损伤。（2）采用对年老化较敏感的行为学指标证实,60~70岁的糖尿病人认知能力显著低于对照组;但60岁以下或70以上病人则少有类似表现。认知阈限理论可解释这一年龄相关现象。（3）Ⅱ型糖尿病人认知功能损伤主要表现为语词记忆损伤、学习能力下降、脑电（P300）潜伏期延长等。（4）认知损伤程度与血糖和胰岛素水平相关,也受高血压等共病因素的影响。控制糖代谢可改善认知功能。糖尿病人的认知损伤与年龄相关,但其机制不同于正常年老化过程中的认知衰退     

Evaluating the predictive validity of a single stimulus engagement preference assessment.

Most preference assessments require individuals to choose among two or more stimuli. More recently, the duration of engagement with items has been used as an index of preference. In the current study, the predictive validity of a single stimulus engagement (SSE) preference assessment was evaluated with 4 individuals. Stimuli were presented singly for a brief period while engagement with that stimulus was recorded. Although SSE preference rankings closely matched paired stimulus preference assessment rankings for only 2 of the 4 participants, relative preference rankings based on duration of engagement predicted relative reinforcer effectiveness for all participants in a subsequent concurrent‐schedule reinforcer assessment. The SSE procedure took less time to administer than the paired stimulus procedure but produced less stable preference rankings across administrations. The SSE procedure may be appropriate for individuals who have difficulty selecting one stimulus from among two or more stimuli, and it may be well suited for evaluating activities that are difficult to present in a paired stimulus format.     

Prime time: Fatigue and set effects in the perception of reversible figures

Subjects viewed unambiguous versions of both stationary and rotating Necker cube illusions for varying durations prior to the presentation of the standard ambiguous figure. In each case, the subjects were more likely to report the ambiguous figure to be (1) in the same configuration as that of the preceding prime following brief preexposure periods and (2) in the opposite configuration from that of the preceding prime following long preexposure-periods. In addition, the number of reversals of the figure during the test period was also strongly related to the duration of the preexposure period, with progressively fewer reversals reported following longer preexposure periods. The results are interpreted as revealing the concurrent roles of “set” effects in the brief preexposure conditions and neural fatigue effects in the long preexposure conditions. Furthermore, the ability of the proposed two-process model to integrate the myriad of empirical effects in the reversible-figure literature is emphasized..     

Supervisory styles index: Examining supervisees' perceptions of Supervisory Style

The goal of this research was to develop an instrument, the Supervisory Styles Index (SSI), that would examine supervisory style. Style has been described as the way in which the personality and convictions of the supervisor are demonstrated in the supervisory relationship (Leighton, 1991). This study focuses on the interplay between supervisory style and the influence of sex and gender. The findings of this study reveal that female supervisees discern their supervisors to be more self-disclosing than do male supervisees. Implications of the findings and utilization of the index are discussed.Portions of this paper were presented at the 52nd annual conference of the American Association for Marriage and Family Therapy, Chicago, Illinois, November, 1994.
