想象训练研究现状的分析

本文采用文献资料法对近十年刊载在中美四种主要期刊上的想象训练研究报告作了分析。结果表明想象训练正在从有效性研究向过程变量研究深化 ,研究面也由简单技术向复杂技术扩展 ,指出了目前复杂技术研究明显不足 ,还指出了基础理论在过程变量控制方面的研究严重滞后 ,在一定程度上影响了想象训练研究的进一步深化。本文为想象训练的研究和应用提供了有益的综合信息。     

我国大学生体质评价体系相关指标有效性和可靠性研究

采用文献资料法、体质测试法、数理统计法、逻辑分析法对当前我国19～22岁大学生体质评价体系指标进行有效性和可靠性研究。结果显示：我国大学生体质评价体系指标应增加“皮脂指标”和“台阶试验”；我国大学生体质评价体系指标中刺激强度较大的耐力性指标和容易受精神因素和激励因素影响的指标的可靠性较差。     

Substituting SAT II: Subject Tests for SAT I: Reasoning Tests: Impact on Admitted Class Composition and Quality

Using data from a sample of 10 colleges at which most students had taken both SAT I: Reasoning tests and SAT II: Subject tests, we simulated the effects of making selection decisions using SAT II scores in place of SAT I scores. Specifically, we treated the students in each college as forming the applicant pool for a more select college, and then selected the top two thirds (and top one third) of the students using high school grade point average combined with either SAT I scores or the average of SAT II scores. Success rates, in terms of first-year grade point averages, were virtually identical for students selected by the different models. The percentage of African American, Asian American, and White students selected varied only slightly across models. Appreciably more Mexican American and Other Latino students were selected with the model that used SAT II scores in place of SAT I scores because these students submitted subject test scores for the Spanish test on which they had high scores.     

DC steady-states analysis of lossy uniform transmission lines

1 Introduction In the past 20 years with the rapid development of VLSI (very large scale integration) circuits and continual spread of electric power system scale, theories on transmission lines have become an important research field where finding the analytic solutions to lossy transmission line equations remains a tough nut. Since the mathematical tool cannot provide effective help, there is no universal method to solve transmission line equations [1]. A number of researchers have obtaine…     

农村信息化公众满意度指数模型研究

文章首先定义了农村信息化公众满意度指数的内涵,然后在定性研究和数理检验的基础上开发了农村信息化公众满意度测量表,并建立了农村信息化公众满意度指数模型.最后,依据上海郊区农村信息化调查数据,运用结构方程模型估计技术对测评模型进行了检验和参数求解.研究表明,文章建立的农村信息化公众满意度指数模型拟合度较高;另外,通过样本数据,得到了各潜在因子之间的路径系数以及可测变量的载荷系数,并对各潜在变量之间的相关关系进行了系统分析,文章在最后就研究发现的农村信息化过程不足提出了建议.     

Evaluation of True Criterion Validity for Unidimensional Multicomponent Measuring Instruments in Longitudinal Studies

Longitudinal studies offer unique opportunities to identify the specificity variance in the components of a psychometric scale that is administered repeatedly. This article discusses a procedure for evaluation of the relationship between true scale scores and criterion variables uncorrelated with measurement errors in longitudinally presented measures comprising unidimensional multicomponent instruments. The approach provides point and interval estimates of the true scale criterion validity with respect to a criterion that is assessed once or repeatedly, as well as a means for testing temporal stability in this validity. The outlined method is based on an application of the latent variable modeling methodology, is readily applicable with popular software, and is illustrated using empirical data.     

行政行为在刑事诉讼中的证据效力研究

行政行为在证据法上的问题,主要是其在诉讼中能否被采纳为证据及其证据的价值问题,也就是它作为证据的可接受性与证据效力问题。     

改进血型实验方法,培养学生综合能力

改进血型定性实验为综合性实验,试制血型诊断抗体和诊断红细胞悬液,满足中学生血型实验试剂需求。自正常A、B型血样分离血清或红细胞,玻片法定性倍比稀释定量检测抗A、抗B,滤菌后冷藏;生理盐水洗涤红细胞,离心沉淀,冷藏。用自制诊断抗体和诊断红细胞悬液与标准试剂对比检测样本60例。自制诊断抗体与诊断红细胞悬液的诊断结果与标准试剂无显著性差异。大学生自制诊断抗体与诊断红细胞悬液基本达到生物制品诊断试剂的标准,大大降低学校用血型试剂成本,也有利于培养大学生综合技能。     

美国一流大学心理健康教育工作的特色分析

美国一流大学的心理健康教育工作具有十分鲜明的特色,主要表现为:心理健康的实质内涵重在健康而非仅指心理;工作形式上注重实效而不断探索有效方式,通过组织研讨活动、学生自我保健教育以及提供健康图书资料等形式深入浅出地对学生进行教育和服务;工作内容上通过专业化道路来提高服务的精深度,日益显现出工作机构专门化、工作人员专业化以及工作趋向医疗化的特点.这些方面充分表明美国一流大学心理健康教育工作的有效性,值得借鉴和学习.     

中国竞技体育生产制度有效性评析

对中国竞技体育"举国体制"予以分析,认为:从中国竞技体育"举国体制"形成的初始条件,到中国竞技体育生产要素禀赋现实,结合中国竞技体育生产项目考察,中国现行的"举国体制"有其存在的一定合理性及优势.然而从制度体系内部的协同性及与外部环境的相容性角度考察,中国竞技体育生产制度并未能发挥其制度优势,制度有效性不足,提出促进中国竞技体育"举国体制"有效性发挥的对策与建议.
