布鲁默学习测验(BLT)中文测题册试用本的编制报告

布鲁默学习测验（ＢＬＴ）是一项以学习模式为研究内容的学习过程测验。作为ＢＬＴ中文版修订工作的首要阶段,课题组在研究ＢＬＴ理论原理,测验结构和内容和基础上,结合我国中小学教学实际,以简单常用的部首和汉字为主要测验材料编制出ＢＬＴ中文版测题册试用本,并作了试测和数据分析。结果表明,试用本具有较高的信度和效度,并保持了作为学习过程测验的特色,达到了研究目的。     

词素的结构对称效应:结构对称汉语成语认知特点的进一步研究

运用词素启动作业,进一步考察了结构对称性汉语成语的识别过程.结果发现(1)无论是用成语的前二个字还是后二个字启动,在成语识别过程中都存在明显的词素结构对称效应,即结构对称成语中的词素启动效应明显大于非对称成语中的词素启动效应.(2)成语的结构对称性、熟悉度和启动词素位置之间存在显著的三阶相互作用.简单效应的分析表明无论成语前二个字还是后二个字启动,词素的结构对称效应均只在低熟悉度成语的识别过程中显著;在前二个字启动时,非对称成语的识别还存在熟悉度效应.     

Evaluation and classification of types of Chinese handwriting deficits in elementary schoolchildren

The handwriting problems of elementary schoolchildren were investigated in this study. A questionnaire for evaluation of Chinese handwriting was developed and then administered to 165 children with handwriting deficits. Factor analysis indicated that the questionnaire has six major dimensions, including construction of characters, accuracy, developmental delay, pencil grip, gross movement, and emotional reaction. These six dimensions were utilized to search for subtypes of handwriting deficits. By further sampling, another 209 children were administered the handwriting evaluation questionnaire to classify their handwriting deficits. According to the severity of deficits on different dimensions of the questionnaire, K-means clustering was utilized to classify the children into four subtypes of mild, severe, motor-originated, and academic learning dysfunction subtypes. The classification by subtype might be helpful in planning interventions for children with handwriting deficits.     

Personality, psychopathology, and demographic correlates of medical vs behavioral reasons for referral in alcoholic men

The personality, psychopathological, and demographic differences between 330 alcoholic men referred for behavioral problems and 104 alcoholic men referred for medical problems were examined. The Minnesota Multiphasic Personality Inventory-2 indicated that those referred for behavioral problems showed more antisocial characteristics, while those referred for medical reasons had more subjective distress, were more highly introverted, and showed greater somatic preoccupation. Hispanic alcoholic men had a significantly higher proportion of medical referrals than Caucasian and African-American alcoholic men.     

真实的思想

哲学在于“指引”。思想是“真”,而非“实”。思想不是某种现实的东西,“真”也不在于符合实在,而在于意义本身。思想是“真”、“实”的统一体。分析哲学运动在“形式化”的进程中,更多地运行在“实”的而非“真”的层面上,因此这场“哥白尼式”的革命运动需要重新审视和定位。     

辩证分析兴奋性氨基酸对神经细胞的双重作用

兴奋性氨基酸（ＥＡＡｓ） 广泛分布于中枢神经系统,参与多种生理过程包括学习、记忆和伤害感受等。然而,ＥＡＡｓ 受体的过度兴奋却可引发一系列细胞事件,最终导致神经元的损伤与死亡。许多神经退行性疾病如早老性痴呆、癫痫和肌侧索硬化症等都与ＥＡＡｓ 的兴奋毒作用有关。目前的研究表明,由ＥＡＡｓ 受体过度兴奋所引发的细胞内钙超载是导致神经元死亡的最终途径     

Perception of classroom environment in Hong Kong: differences between students in junior and senior forms

In Hong Kong secondary schools, students in the senior forms take competitive examinations to proceed to the next level, whereas those in the junior forms have to attend school regardless of their ability and motivation. It was hypothesized that this produces different classroom climates. To test this hypothesis, 602 Chinese secondary school students were administered the short version of the Classroom Environment Scale. Significant differences were found, varying by type of school, on the dimensions of Involvement, Task Orientation, Teacher Support, Competition, Order and Organization, Affiliation, Innovation, Rule Clarity, and Teacher Control. These findings are discussed.     

Uptake of Cardiac Screening and Genetic Testing Among Hypertrophic and Dilated Cardiomyopathy Families

Cardiomyopathy is a genetically and clinically heterogeneous, life threatening disease which affects people of all ages. Recent guidelines provide recommendations for cardiac screening and genetic testing in at-risk relatives, but the uptake and impact of these measures in the United States is unknown. This is a single institution retrospective study that characterizes the uptake of cardiac screening and genetic testing for relatives of a cohort of 57 probands with hypertrophic (HCM) and dilated cardiomyopathy (DCM) who underwent both clinical evaluation and genetic testing. Cardiac screening was indicated for 302 relatives. One hundred and seventy-three (57 %) completed cardiac screening. Forty of the 57 probands were mutation positive and genetic testing was indicated for 213 relatives. Eighty-four (39 %) completed genetic testing. The uptake of cardiac surveillance was greater than the uptake of genetic testing (p?<?0.0001) among relatives of mutation positive probands. Within the group of at-risk, asymptomatic relatives of probands, cardiac screening and genetic testing were positive in 25 % and 40 % of cases, respectively. These data demonstrate the important role and utility of cascade cardiac screening and genetic testing in the care of patients and families with HCM or DCM. The approach to cardiac screening and genetic testing should be family-specific and requires expertise in the genetics of cardiomyopathy.
