从教育测验到教育评论相关概念及其关系的辨析

人类对教育进行事实判断和价值判断,走过了从教育测验到教育评论的历程,形成了教育测验、教育统计、教育测量、教育评估、教育评价、教育评论理论,并且这一学科群落已经形成。但由于这些理论和学科群落并不成熟,许多人对该学科群落的相关概念及其关系认识不清。因此,很有必要从多角度对该学科群落的相关概念及其关系进行辨析,并对该学科群落建设进行有益的探索。     

零售商态度承诺和供应商权力使用间的互动关系研究

本文研究了零售商不同的态度承诺与供应商权力使用间的互动关系。通过对中国346对家用电器零售商--供应商关系的问卷调查,利用因子分析及结构方程模型验证了概念模型及假设。本文研究结果表明:供应商强制性权力的使用会增加零售商的算计性承诺,降低其忠诚性承诺,而供应商非强制性权力的使用会增加零售商的忠诚性承诺。同时零售商的算计性承诺会促使供应商更多地使用强制性和非强制性权力,而零售商的忠诚性承诺则会减少供应商强制性权力的使用,增加供应商非强制性权力的使用。     

图书馆学的科学化与合理性

提出图书馆学的科学化和合理性问题。认为以图书馆这一人文社会现象作为自己研究对象的图书馆学,不可能实现绝对科学化和客观性,图书馆学科学化的实质是图书馆学的合理性,即合规律性与合目的性的统一,构建合理性图书馆学理论必须坚持科学实证与哲学人文建构相结合。     

Association between mandibular posterior alveolar morphology and growth pattern in a Chinese population with normal occlusion

Objective:To investigate the relationship between growth patterns and mandibular posterior tooth-alveolar bone complex morphology in a Chinese population with normal occlusion.Methods:Forty-five patients with normal occlusion(23 males,22 females) were included in this study.Among these patients,20 displayed the vertical growth pattern,and 20 had the horizontal growth pattern,while the remaining patients displayed the average growth pattern.All of the patients underwent dental cone beam computed tomography(CBCT),which included the region of the mandibular posterior teeth and the alveolar.A linear regression analysis and a correlation analysis between the facial height index(FHI) and the alveolar bone morphology were performed.Results:The inclination of the molars,the thickness of the cortical bone,and the height of the mandibular bone differed significantly between patients with the horizontal growth pattern and those with the vertical growth pattern(P<0.05).Significant positive correlations were found between:the FHI and the inclination of the molars;the FHI and the thickness of the cortical bone;and the FHI and the height of the mandibular bone.Conclusions:The mandibular posterior tooth-alveolar bone complex morphology may be affected by growth patterns.     

从跨文化角度看《红楼梦》中的称谓翻译

中文中的称谓语往往体现着交际双方的身份地位、学识修养以及亲疏程度,但英文中的称谓语却很难体现出这些。因此如何将汉语的称谓语准确无误地翻译成对应的英语称谓语显得非常重要。在《红楼梦》的两大译本中霍克斯和杨宪益都尽其所能对称谓语进行了翻译,通过对比他们对称谓语的翻译,可以得出在翻译称谓语时,首先应该注重原文称谓语的所指,其次应该注重原文称谓语的文化内涵。     

浅谈如何跨越试题中的“陷阱＂

我们把试题针对学生学习和研究物理问题在认识上的片面性而有意设置时干扰信息和障碍，称为“陷阱”．这类试题充分体现了素质教育的基本要求和考核方向，笔者通过对试题的分析，认为这类试题可分为五类，解题时只要明确目的，理清思路，就能发掘和跨越“陷阱”．

Novel high torque bearingless two-sided rotary ultrasonic motor

Applications are limited at present because the currently available ultrasonic motors (USMs) do not provide suffi-ciently high torque and power. The conventional travelling-wave USM needs the bearing to support, which required lubricant. To solve the above problem, a bearingless travelling-wave USM is designed. First, a novel structure of the two-sided USM consisting of a two-sided teeth stator and two disk-type rotors is designed. And the excitation principle of the two-sided travelling-wave USM is analyzed. Then, using ANSYS software, we set up the model of the stator to predict the excitation frequency and modal response of the stator. The shape of the vibration mode was obtained. Last, the load characteristics of the USM are measured using ex-perimental method. The maximum stall torque and the no-load speed were obtained. The results showed that the characteristics of the two-sided USM are better than those of the conventional one-sided USM.     

大学教学质量定位的新视角：基于契约理念的分析

契约理念主要包括自由意志观念、义务责任观念与诚实信用观念。随着教育实践的深刻变革,学校与学生之间已经形成了实然的契约关系。在契约理念指导下。大学由“行政管理规训者”转变为“教学服务的提供者”,“学生产品观”已转变为“服务产品观”,教学服务的适切性与敏捷性成为教学质量的内在要求。
