以大工程意识指导工程训练教学基地建设

近些年，许多院校参照香港理工大学工业中心的经验和模式，利用世行贷款、211工程或自筹资金建设了各具特色的工程训练中心。哈尔滨理工大学在工程训练中心的规划和建设中以大工程意识为指导，将工程训练中心建设成为以金工实习为主，相关课程实验、大学生创新制作和科技竞赛、地区性职业培训和工程认证、新产品孵化和中试等为辅的综合性训练基地，并为机械工程等相关学科建设服务。     

Formative assessment: the role of participatory action research in blending policy and practice in Uganda

This paper documents teachers’ assessment practices and pupils’ learning to read and write in large classes. To gain insights into the assessment practices and pupils’ learning, the principles of Vygotsky’s zone of proximal development and participatory action research (PAR) design were adopted. Collaboratively, teachers reflected on their assessment practices, developed, implemented and monitored the assessment practices. Through observation, in-depth interview and review of exercise books, data were obtained. We argue that teachers’ involvement in PAR has contributed to changing assessment practices in large classes and in improving pupils’ competencies in reading and writing. On the other hand to promote better assessment practices, we advocate for reduced number of pupils in a class and teachers’ workload to enable them offer more support to the pupils during assessment of reading and writing.     

中美高等工程教育课程设置比较

20世纪90年代以来,美国工程教育掀起了“回归工程”的浪潮,提出建立“大工程观”。要想实现大工程观所要求的高等工程教育改革,必须在课程体系和内容的改革上下功夫。通过对中美高等工程教育在政府和市场对课程设置的影响程度,课程体系建设,学科之间联系以及对学生能力培养等方面的比较,可以看出,美国在高等工程教育的课程设置和教学改革方面积蒜了丰富的经验,值得我国高等工科院校借鉴。     

大型循环流化床环形炉膛中气固流动特性的CPFD数值模拟

环形炉膛理论上可有效解决大型循环流化床中二次风穿透不足的问题,其内外环壁面的设计也为更多的受热面提供了充足的空间,是一个具有明显优势的新型炉膛结构.本文使用CPFD数值模拟方法,对循环流化床环形炉膛冷态实验台内气固流动特性进行研究.模拟得到的炉内轴向压力分布和返料流率均与实验结果吻合较好.在此基础上分析炉内气固流动特性以及炉膛出口气固流动不均匀性,研究结果为环形炉膛的设计优化提供有价值的信息.

英国集团公司债务的大股东责任问题研究

英国法以法人格独立性为基础,来处理集团公司的债务责任。一般情况下,作为大股东的母公司对子公司并不承担任何债务责任。但是,英国通过１９８６年支付不能法和１９８９年公司法,建立了大股东对集团公司债务承担责任的法律根据,这对我国企业集团立法具有积极的启示。     

Examining Chi-Square Test Statistics Under Conditions of Large Model Size and Ordinal Data

This study examined the effect of model size on the chi-square test statistics obtained from ordinal factor analysis models. The performance of six robust chi-square test statistics were compared across various conditions, including number of observed variables (p), number of factors, sample size, model (mis)specification, number of categories, and threshold distribution. Results showed that the unweighted least squares (ULS) robust chi-square statistics generally outperform the diagonally weighted least squares (DWLS) robust chi-square statistics. The ULSM estimator performed the best overall. However, when fitting ordinal factor analysis models with a large number of observed variables and small sample size, the ULSM-based chi-square tests may yield empirical variances that are noticeably larger than the theoretical values and inflated Type I error rates. On the other hand, when the number of observed variables is very large, the mean- and variance-corrected chi-square test statistics (e.g., based on ULSMV and WLSMV) could produce empirical variances conspicuously smaller than the theoretical values and Type I error rates lower than the nominal level, and demonstrate lower power rates to reject misspecified models. Recommendations for applied researchers and future empirical studies involving large models are provided.
