克龙巴赫α系数研究述评

克龙巴赫α系数足表征测验内部一致性信度的重要指标,在心理和教育测量中应用十分广泛,而其理论上的局限性也备受研究工作者的关注.本文就近年来关于α系数的应用和研究做了简要梳理,并对α系数在实际应用中需要注意的问题进行了总结和探讨.     

Implementation in a Changing Landscape: Provider Experiences During Rapid Scaling of Use of Evidence-Based Treatments

This study examined 133 service providers’ perspectives on a rapid shift to mandated evidence-based treatment delivery, utilizing an inductive coding process to capture themes present in their qualitative feedback. The majority of provider comments were negatively valenced, but attitudes varied considerably across response categories: comments regarding practice context and support were nearly uniformly negative, while comments regarding treatment fit and therapeutic consequences were more balanced. Treatment fit was the most commonly cited category; the fit to therapist (e.g., ease of use) subcategory was predominantly positive in contrast with the fit to client (e.g., flexibility) subcategory, which was predominantly negative. Results illustrate the intended and unintended consequences of large-scale implementation efforts on community providers, and may aid implementation researchers and system decision makers optimize the conditions under which community providers are asked to implement evidence-based treatment.     

中国心理学研究的现状与发展——基于第二十二届全国心理学大会的分析

采用Bicomb及SPSS软件对第二十二届全国心理学大会进行统计分析,探讨中国心理学的研究现状及发展趋势。本届会议分为31个专题,共收录1295篇论文摘要,产生42个高频关键词。研究结果表明,中国心理学目前仍处在蓬勃发展期,门类分支较细,研究成果丰硕,研究机构主要以师范类院校及专业研究结构为主; 关键词共词分析发现中国心理学研究具有五个热点领域。未来应进一步做好纵向研究,采用更为先进的研究方法,并结合心理学分支领域的会议来判断中国心理学研究的现状及发展。     

群际态度与群际信念:耦合还是分离?

群际态度是人们对于某一群体的喜欢或不喜欢,包括外显群际态度和内隐群际态度,它是一个群体对另一群体正负连续体的评价。群际信念是人们对某一群体特性的刻板印象。以往研究认为,群际态度和群际信念是耦合关系,相互影响,相倚存在。但群际态度和群际信念也存在分离性证据,即存在矛盾性和非统一性。为何形成耦合或者分离,文化定型论、群际态度补偿机制(低地位群体的创造策略、高地位群体的慷慨策略),以及认知差别等都成为调节性平衡点。探讨群际态度和群际信念的分离性关系和作用机制对于干预和消弭群际边界与群际冲突,缓和群际关系具有深远影响,可以支持其独立路径予以针对性干预方案。     

Career adaptability,calling and the professional competence of social work students in China: A career construction perspective

Based on career construction theory, the current research examined individual and contextual predictors for the professional competence of Chinese undergraduates majoring in social work (N = 270). Results showed that career concern and career curiosity predicted social work students' professional competence, with these relations mediated by the calling in social work. It was also found that the positive effect of calling on professional competence was stronger among students who perceived a lower level of career-oriented learning environment. The corresponding moderated mediation model was supported such that the indirect effects of career concern and career curiosity on professional competence were stronger among students who perceived a lower level of career-oriented learning environment. These findings carry implications for research on career construction theory, as well as career education and career counseling practices.     

一日龄小鸡的记忆保持及其与脑内加压素（AVP）含量的相关研究

以一日龄小鸡为实验对象,进行一次性厌恶回避反应训练,并应用加压素的放射免疫测定法,分析比较记忆保持测验中,成绩优、劣及对照组动物与其脑内加压素含量的相关。实验结果表明,记忆保持良好的动物,脑内加压素含量明显低于对照组和记忆不良组,而记忆不良组与对照组之间则无明显差异。提示在正常生理状态下,加压素参与记忆过程的调制,并可能在这一过程中有一定的耗竭或合成减少,如适时得以补充,则对记忆的巩固和再现起易化作用。     

氯丙嗪、氯丙嗪-苯丙胺颉颃作用对猕猴学习和行为的影响

精神药物对学习和行为影响的实验研究。开始于氯丙嗪和二乙基麦角酰胺(LSD)的诞生。自从1954年首次报道氯丙嗪对精神病患者的疗效后,精神药物对学习和行为影响的研究一直十分引人注意。早期的研究强调精神药物和学习的动机有关,因此以食物巩固为基础的正动因学习和以电击巩固为基础的负动因学习间,被认为存在本质差     

活体肝移植的伦理学问题

目前,肝移植已成为治疗终末期肝病的有效手段,活体肝移植术部分解决了供肝短缺的问题,10多年来其发展迅速,并取得了良好的疗效,由于活体肝移植需从活的供体身上切取部分肝脏,且供体多为患者家属,故存在着供体的选择,供体的贡献与代价,患者的家庭,心理,社会等伦理等问题。因此在提高活体肝移植技术水平的同时,必须充分考虑活体肝移植的伦理学问题,遵守伦理原则,使活体肝移植不但能从技术上达到,在伦理学方面也是可行的。     

《老君戒经》及《老君音诵诫经》中的道乐史料研究

北魏时期是道教改革和道乐形成的重要时期,此期间道乐史料集中于北天师道领袖寇谦之。由于以往学术界在史料挖掘研究上未臻佳境,致使对寇氏的评价失之拔高。本文基于两种重要原始资料的整理研究,对寇氏在道乐史上的作用和地位提出新的认识和评价。
