原位反应烧结制备生物陶瓷

羟基磷灰石是人体硬组织中主要的无机成分,与人体组织具有良好的生物相容性,并能与骨组织形成骨性结合.对不同配方的原料预先进行压制成型,采用原位反应法在1 100℃烧结70 min制备多孔生物陶瓷,并对陶瓷的物相、微观相貌及吸水率进行了研究.实验结果表明:添加Y2O3,对合成HA的反应的催化效果最好,生成的生物陶瓷性能最佳.     

心理测验的效度与长度的关系探析

信度与效度是衡量心理测验质量的重要指标。增加测验长度是提高测验信度和效度的重要方法之一。由于各学者对效度的代表符号规定不一，导致对于说明测验长度与测验效度关系的公式及其计算结果难于理解和解释。根据经典测量理论对代表测验长度与测验效度关系的公式进行分析和讨论，提出测验效度与长度关系的表达公式。     

Building the vocational phase of the computerized motor skills testing system for use in the Electronics and Electrical Engineering Group and Hospitality Group

Technical and vocational education emphasizes the development and training of hand motor skills. However, some problems exist in the current career and aptitude tests in that they do not truly measure the hand motor skills. This study used the Nintendo Wii Remote Controller as the testing device in developing a set of computerized testing tools to measure the hand motor skills. Through literature analyses, expert reviews, and analysis of the experimental data, it has been confirmed that these computerized testing tools are stable and effective; in addition, the test results were not influenced by gender or prior experiences with using sensor devices. Moreover, the computerized test was capable of diagnosing and measuring the hand motor skills of participants in a safe, low-cost, virtual testing environment. In focusing on the learning experiences from vocational school practice classes, this study provides a reference for decision-making regarding further education and career development.     

Emission Performance of Motorcycles in Real-Road Conditions

WMTC,which means a worldwide motorcycle testing cycle,is now regarded as the most possible choice for the global motorcycle emission testing cycle,but whether or not it can be used in China is still unknown.In this study,a large number of data on the speed-time trace of motorcycles were sampled from various kinds of roads in 5 cities in China.Based on a series of criterion numbers defined,the driving character of motorcycles in the real-road conditions of China was obtained.With the aid of a specially designed program,an emission testing cycle that can indicate the driving characteristics of motorcycle in the real-road conditions was synthesized,and the exhaust emission tests of 20 motorcycles under the synchronized cycle and WMTC were carried out based on a CVS system and a motorcycle chassis dynamometer.The results show that although there do exist differences in some criterion numbers between the real-road condition and WMTC,such as proportion of idling mode,mean speed,mean running speed and the average acceleration and deceleration rates,the driving behaviors are similar.The results of exhaust emission tests indicate that the emission values of motorcycles under the synchronized cycle and WMTC have a relatively strong correlation.This means that WMTC can be introduced as a standard motorcycle emission test regulation into China.     

4～7岁儿童空间认知和推理能力的测试研究

4~7岁儿童对空间图形的正确认识总体上处于较好水平.对图形和空间认知成绩的快速提高期出现在5岁半~5岁11个月(学龄前),对点数、推理能力的认知成绩的快速提高期出现在7岁~7岁5个月(初入学).与自然因素、基因遗传相比,人与环境间的互动作用,是儿童发展的主要的和根本的原因.我们既不能忽视自然成熟的因素,又须重视教育的重要影响.     

Testing agile requirements models

This paper discusses a model-based approach to validate software requirements in agile development processes by simulation and in particular automated testing. The use of models as central development artifact needs to be added to the portfolio of software engineering techniques, to further increase efficiency and flexibility of the development beginning already early in the requirements definition phase. Testing requirements are some of the most important techniques to give feedback and to increase the quality of the result. Therefore testing of artifacts should be introduced as early as possible, even in the requirements definition phase.     

School Counselors' Perceptions of Career Counseling and Career Testing: Preferences, Priorities, and Predictors

Limited information on the actual and preferred career counseling and career testing activities of school counselors exists. An analysis of a statewide school counselors' survey revealed career counseling and testing preferences, priorities and predictors. Results revealed counselors preferred trait/factor approaches to career counseling, including Holland's RIASEC theory, Person-Environment-Correspondence theory and Cognitive Information Processing theory, respectively. With respect to career counseling and career testing priorities, means comparisons indicated that elementary, middle, and high school counselors' actual time performing career counseling duties is minimal; however, they desire to spend significantly more time on career counseling and testing. Multiple regressions revealed important predictor variables for actual and ideal time spent on career counseling and career testing. Limitations and recommendations for further research are discussed.     

Improving student outcomes in high‐enrollment statistics classes with the structured writing approach

The article describes an assignment that makes writing‐to‐learn feasible in high‐enrollment statistics classes. It combines the principles of structured writing with Bloom's taxonomy. The assignment helped improve related exam scores and was easy to implement and grade for instructors.
