字形系联与幼稚园的识字教学

本研究根据汉字形义系联的特性设计字形系联识字法,并且进行教学实验。研究发现采用字形系联识字法较诸传统识字法,无论在形音义的辨认正确率都有显著差异．而且时问越久,差异越大。字形系联识字法的形音义相关系数很高,但教材编排的次序对辨识正确率无显著差异。     

2型糖尿病的营养干预策略

2型糖尿病的发病率日益增加,已成为影响人类健康的主要疾病之一.糖尿病的高糖、高脂状态可使活性氧化物产生增多,造成氧化应激;氧化应激与糖尿病的发生与发展密切相关,通过联合补充抗氧化微量营养素VitE、VitC、Zn及Se,以及多选用含抗氧化物食品,可有效地降低氧化应激,从而阻止或延缓糖尿病病情的进展.     

Screening for borderline personality disorder in outpatient youth

Young people with borderline personality disorder (BPD) commonly seek help but often go unrecognized. Screening offers a means of identifying individuals for more detailed assessment for early intervention and for research. AIMS: This study compared the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Borderline Personality Questionnaire (BPQ), the BPD items from the International Personality Disorder Examination Screening Questionnaire and the BPD items from the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II) Personality Questionnaire. METHOD: 101 outpatient youth (aged 15-25 years) completed the screening measures and were interviewed, blind to screening status, with the SCID-II BPD module. The screening measures were readministered two weeks later to assess test-retest reliability. RESULTS: All four instruments performed similarly but the BPQ had the best mix of characteristics, with moderate sensitivity (0.68), the highest specificity (0.90), high negative predictive value (0.91) and moderate positive predictive value (0.65). Compared to the other three instruments, the BPQ had the highest overall diagnostic accuracy (0.85), a substantially higher kappa (0.57) with the criterion diagnosis, the highest test-retest reliability (ICC = 0.92) and the highest internal consistency (alpha = 0.92). The only clear difference to emerge in the Receiver Operator Curve (ROC) analysis was that the BPQ significantly outperformed the MSI (p = 0.05). CONCLUSION: Screening for BPD in out-patient youth is feasible but is not a replacement for clinical diagnosis.     

大学生生涯成熟状况及与自我同一性关系研究

"职业生涯规划"教育在各高校受到极大关注,但辅导成效甚微,缺少实证研究、缺乏针对性是其深入拓展的障碍.本研究采用自编的<生涯成熟度量表>,测查大学生生涯成熟特点及与自我同一性关系,结果表明:大学生生涯发展的总体水平不是很高;受性别、年级、父母期望、兼职经验等因素影响;不同自我同一性地位大学生的生涯成熟状况存在差异.     

领导行为:企业并购整合研究的新方向

过去一个世纪以来,国际性兼并、收购和战略联盟急剧增多,然而大部分并购案例均以失败告终,无法达到其原定目标,有的甚至使企业陷入困境.导致并购失败的最主要原因是并购后的整合失败,并非战略与财政不当.领导行为在组织变革和组织再造过程中起着关键性作用,但其在组织并购整合过程中的作用却一直被研究者忽视.全球范围内并购浪潮的持续增长要求领导者迅速提升自身的应对能力,但领导在组织并购整合中的作用机制尚待深入研究.本文介绍了企业并购整合过程中所需的基本领导模式、相关研究的理论基础与方向,以期为提高并购整合活动的领导效力及深入研究提供参考.     

群际宽恕的影响因素

群际宽恕(Intergroup Forgiveness)是指对曾经侵犯过本群的外群所具有的报复感、愤怒感以及不信任感的减少, 有意识地去理解、接近对方群体, 并积极地参与到对方群体中去的一种心理过程。学界对影响群际宽恕的因素进行了深入的研究, 分析了低人性化、竞争受害性、群体认同、愤怒、共情、道歉以及群体接触7个因素对群际宽恕产生的影响作用; 同时, 以影响因素的研究结论为基础, 不同的学者提出了提升宽恕水平, 缓和群体关系的干预性建议。但是, 作为一个新的研究主题, 还需要深入探讨群际宽恕的内部过程机制, 积极建立符合本土文化的干预模型。     

The impact of supervisory mentoring on personal learning and career outcomes: The dual moderating effect of self-efficacy

Using survey data from 226 employees and their supervisors in four manufacturing companies in China, we found that employee self-efficacy has a dual moderating effect on the impact of supervisory mentoring on subordinate career outcomes. Path analytic tests of mediated moderation suggested that self-efficacy moderates the mediated effects of supervisory mentoring on job performance and career satisfaction through personal learning such that the mediated effect on job performance is stronger when employees have higher self-efficacy, but the mediated effect on career satisfaction is stronger when they have lower self-efficacy.     

Memory skills mediating superior memory in a world-class memorist

Laboratory studies have investigated how individuals with normal memory spans attained digit spans over 80 digits after hundreds of hours of practice. Experimental analyses of their memory skills suggested that their attained memory spans were constrained by the encoding time, for the time needed will increase if the length of digit sequences to be memorised becomes longer. These constraints seemed to be violated by a world-class memorist, Feng Wang (FW), who won the World Memory Championship by recalling 300 digits presented at 1 digit/s. In several studies we examined FW’s memory skills underlying his exceptional performance. First FW reproduced his superior memory span of 200 digits under laboratory condition, and we obtained his retrospective reports describing his encoding/retrieval processes (Experiment 1). Further experiments used self-paced memorisation to identify temporal characteristics of encoding of digits in 4-digit clusters (Experiment 2), and explored memory encoding at presentation speeds much faster than 1 digit/s (Experiment 3). FW’s superiority over previous digit span experts is explained by his acquisition of well-known mnemonic techniques and his training that focused on rapid memorisation. His memory performance supports the feasibility of acquiring memory skills for improved working memory based on storage in long-term memory.     

数列推理项目的难度模型构建

研究基于数列推理项目的认知模型归纳整合和丰富了数列推理项目的刺激特征,基于这些刺激特征生成了92个数列题目,组成四套不同的测验,共给466名学生施测。结果表明:测验的EAP信度为0.87,其中双层运算项目适合高水平能力被试;刺激特征及其交互作用显著影响题目难度;使用LLTM模型构建项目难度模型,该模型可以有效预测项目难度,预测项目难度和实测项目难度的相关为0.85。这说明研究选择和拓展的刺激特征能够显著增加和预测题目的难度。     

速度与调式在诱发情绪反应中的作用:来自中西方传统音乐的证据

以24名本科生为实验对象,采用12段剪辑音乐为材料,使用多导生理记录仪考察其调式和速度在诱发情绪反应中的作用。结果发现:(1)主观情绪自评指标,速度与调式的主效应及交互效应显著,快速、大调音乐的主观自评值显著高于慢速小调音乐;(2)西方传统音乐在心率指标上,速度和调式主效应显著,快速、大调音乐的心率值高于慢速小调音乐;(3)中国传统音乐在心率、皮电指标上,速度、调式主效应显著,快速、大调音乐的心率和皮电值高于慢速小调音乐,皮温指标上,调式主效应显著,大调音乐的皮温值高于小调音乐。这表明不同速度和调式音乐诱发了不同的情绪反应,不同调式中国与西方音乐在诱发情绪反应上存在差异。
