大学生对心理健康必备能力认知的年级与性别特点

本研究以200名大学生为被试,以访谈及问卷的方式对大学生心理健康必备能力的认知特点进行了调查研究,在大学生心理健康必备能力认知结构模型的基础上,对大学生心理健康必备能力认知的年龄与性别特点进行了研究。结果表明:大学生对心理健康必备能力的认知得分在自我调控、社会应对、学习和人际交往四个因子上没有显著的年级和性别主效应;在“社会应对”和“学习”两个维度上,性别和年级存在显著的交互作用,进一步分析发现,二年级男生在“社会应对”方面能力的认知得分显著高于女生,在“学习”维度上,一年级女生得分显著高于男生。     

不同背景噪音干扰下的数字短时记忆研究

以三种类型(交通噪音、生活噪音、舒缓乐音)三种声级(40.7dBA、56.4dBA、73.3dBA)的环境噪音作为无关声音刺激,考察其对数字短时记忆广度和Sternberg任务的影响,发现:(1)背景噪音的不同对个体数字短时记忆广度影响没有显著差异;(2)背景噪音声级的不同对个体删除极端数值后正确反应的反应时及对“极错总比率”都有显著的影响;(3)对于删除极端数值后的正确反应来说,在不同背景噪音存在下,随着记忆集的增大,反应时仍然呈直线上升趋势。     

浅谈内隐学习在大学英语教学中的应用

内隐学习是一种自动的、不易觉察的、对复杂规律敏感的学习,内隐学习与学科教学的结合是近年来内隐学习研究取得的新进展。结合大学英语教学的实际,对内隐学习在大学英语教学中的应用进行了思考并提出了几点认识。     

两种水化疗法对预防对比剂肾病的效果研究

比较两种水化疗法对对比剂肾病(contrast-induced nephropathy,CIN)的预防效果。将150例患者随机分为氯化钠水化组(50例)、碳酸氢钠水化组(50例)和常规治疗组(50例),检测患者造影前3天内及造影后第3天、7天的血肌酐、尿素氮和尿β2微球蛋白。分析三组患者CIN的发病率。结果两水化组CIN的发病率均显著低于常规治疗组(P0.05),两水化组间CIN的发病率无明显差异(P0.05)。结果提示两种水化疗法对CIN的预防效果相仿。     

急性高原病易感人群筛选研究的一些思考

高原缺氧存在易感人群,目前对高原易感人群的筛查主要从进入高原前后人体功能、组织因子及蛋白的变化等方面进行研究,有学者开始从基因水平筛查高原易感人群,基因研究虽然面临许多困难,但它可能是高原易感人群筛查中最有前景的研究方法,应是今后研究的重要方向。

缺血后适应脑保护的耗散结构基础与脑缺血损伤的非线性特征

脑缺血损伤的机制十分复杂,主要内容涉及谷氨酸兴奋毒性、Ca2＋毒性、自由基损伤、一氧化氮损伤、炎性反应以及内质网和线粒体功能障碍等,这些复杂的机制网络具有耗散结构的非线性特征。近年发现缺血后适应可能通过P13K、Akt、MAPK、PKC等通路,KATP通道,抗凋亡等方式阻止或减轻损伤,从而实现脑保护,而形成一个复杂的信号转导体系。而对复杂的生命系统的研究起着指导作用的耗散结构理论是从更高水平层次研究复杂系统的系统科学,文中将从哲学的角度阐释缺血后适应产生大脑保护的耗散结构基础。     

Internet-delivered physical activity intervention for college students with mental health disorders: a randomized pilot trial

The prevalence of mental health disorders among college students is rising and the increasing rates of anxiety and depression have important societal implications. Physical activity has been proposed as an adjuvant to traditional treatment approaches (i.e. psychotherapy or pharmacotherapy), and the internet is a potentially useful means of delivering physical activity information to the college-aged population. This randomized pilot trial examined the effects of an internet-based physical activity intervention on physical activity, self-efficacy, depression, and anxiety in college students (n?=?47) receiving mental health counseling. Physical activity, depression, anxiety, exercise self-efficacy, and barriers self-efficacy were assessed at baseline and post-intervention. There was a significant time effect for physical activity, with both groups increasing their physical activity levels across the 10-week intervention but with a larger increase in the intervention condition (d?=?0.68) than the control condition (d?=?0.05). Exercise and barriers self-efficacy declined across the intervention, but more so in the control than intervention condition. Effects on depression and anxiety were nonsignificant. Finally, correlation analyses showed increases in physical activity were associated with increases in exercise self-efficacy (r?=?0.62) and barriers self-efficacy (r?=?0.63) and decreases in depression (r?=?-0.44) in the intervention condition, but not in the control condition. These results suggest that an internet-delivered physical activity intervention may be a promising approach to promoting physical activity among college students undergoing mental health counseling.     

Standard back-translation procedures may not capture proper emotion concepts: a case study of Chinese disgust terms

We present data questioning the adequacy of standard back-translation procedures for investigating emotion states across cultures (Brislin, 1970). Our data indicate that the Chinese back-translation of the term disgust has led cross-cultural researchers to accept terms whose themes, goals, and motivations are more akin to the English term anger. Evidence is presented showing that, compared with the standard back-translation method, a more painstaking interview method found a better translational Chinese equivalent for the English term disgust. Implications for the use of back-translation in cross-cultural research are considered.     

目标定向、自我效能感与主观幸福感的关系

以207名企业员工为研究对象,探讨了目标定向、自我效能感与主观幸福感的关系及自我效能感在目标定向和主观幸福感之间的中介作用。结果表明:学习目标定向、工作自我效能感和社交自我效能感均对主观幸福感有着显著的正向影响;主观幸福感对任务绩效有着显著的正向影响;同时,工作自我效能感在学习目标定向和主观幸福感之间起着完全中介作用。
