一流大学建设背景下教师绩效评价的思考     

胡赤弟  王依琳 《宁波大学学报(教育科学版)》2020,(1):67-72

“双一流”建设的一项重要任务就是要加快一流教师队伍建设。在梳理了高校教师绩效评价制度发展历程的基础上,发现当前大多高校教师绩效评价存在评价导向不统一、评价标准不协调、评价主体行政化、反馈机制不畅通等问题。因此,高校教师绩效评价要体现战略导向,树立以人为本的理念,扩大评价的参与度和参与面,创新评价的方式方法,打造高素质的教师队伍,为一流大学建设目标的实现奠定夯实的人力资本基础。  相似文献

Adaptive Observer-Based Fault Estimate for Nonlinear Systems     

宗群  刘文静刘利 《天津大学学报(英文版)》2006,12(6):425-428

In recent years, fault detection and isolation(FDI) technologies have been developing rapidly.Among them the observer-based fault detection andisolation technology for nonlinear systems are the mostattractive research areas, and lots of promising resultscan be found in survey papers[1]. Generally, thereare several kinds of strategies for observer-based FDIin nonlinearsystems such as unknown inputs observer-based FDI[2], and adaptive observer-based FDI[3].

Study of CNG/diesel dual fuel engine's emissions by means of RBF neural network     

刘震涛  费少梅 《浙江大学学报(A卷英文版)》2004,5(8):960-965

Great efforts have been made to resolve the serious environmental pollution and inevitable declining of energy resources. A review of Chinese fuel reserves and engine technology showed that compressed natural gas (CNG)/diesel dual fuel engine (DFE) was one of the best solutions for the above problems at present. In order to study and improve the emission performance of CNG/diesel DFE, an emission model for DFE based on radial basis function (RBF) neural network was developed which was a black-box input-output training data model not require priori knowledge. The RBF centers and the connected weights could be selected automatically according to the distribution of the training data in input-output space and the given approximating error. Studies showed that the predicted results accorded well with the experimental data over a large range of operating conditions from low load to high load. The developed emissions model based on the RBF neural network could be used to successfully predict and optimize the emissions performance of DFE. And the effect of the DFE main performance parameters, such as rotation speed, load, pilot quantity and injection timing, were also predicted by means of this model. In resume, an emission prediction model for CNG/diesel DFE based on RBF neural network was built for analyzing the effect of the main performance parameters on the CO, NOx emissions of DFE. The predicted results agreed quite well with the traditional emissions model, which indicated that the model had certain application value, although it still has some limitations, because of its high dependence on the quantity of the experimental sample data.  相似文献

Numerical investigation of microtexturing rings’ structure on the friction performance of bearing cells     

PENG Yun-feng  KANG Shuang-yang  SU Xing 《重庆大学学报(英文版)》2017,16(3):98-112

We presented a numerical examination of the effect of microtexturing negative rings’ structure on the tribological performance of parallel bearing couples’ cell. Three mcirotexturing rings, which are circle, square and ellipse, were chosen and the analysis model were established. We used the Reynolds equation coupled with finite difference method and successive over relaxation Gauss-Seidel iterative method to solve the Newtonian flow’s hydrodynamics within a bearing couple. The effect of texture density and radius ratio (thickness) of the microtexturing rings were investigated on the tribological performance under the similar operating conditions. The numerical simulation reveals that: 1) The microtexturing rings’ structure can homogenize the local pressure much uniformly within the bearing cell. 2) The tribological performance is determined mainly by the microtexturing rings’ geometry and texture density, and the thickness of the rings’ structure can help to change the quantitative values. 3) The square and circle rings’s microtexturing surface can slightly improve the frictional performance with the bearing cells’ gap, while the ellipse ring’s surface may decrease the frictional performance. 4) The ellipse rings’ microtexturing surface can achieve the minimum spacing gap but the maximum friction coefficient of the bearing couple, and then the circle and square rings’ structure take the second and third place, respectively  相似文献   

Investigating gender differences in mathematics by performance levels in the Italian school system     

《Studies in Educational Evaluation》2021

Amongst the extensive research conducted about girls’ lack of interest in STEM subjects, an issue that is frequently examined is the learning of mathematics. This research investigates the gender gap in mathematics among Italian students based on performance levels, using standardised large-scale data from INVALSI tests. We performed a quantile regression to better understand the differences along the entire score distribution. A latent class model was then estimated to identify groups of students with similar performance levels, taking into account the gender covariate. The results indicate that boys are already ahead from primary education and that there is a general decrease in the performance as students progress through the education stages.  相似文献

资源整合视角下高职院校产教融合绩效评价研究     

陈新民  高飞  张朋  王一涛 《高等工程教育研究》2021,(2):155-162

从资源整合视角出发,产教融合即院校通过与产业界的合作,推动不同资源的重组与优化,从而实现双方的共生演进、有机融通及协同创新。以应用型人才培育能力、科学研究综合竞争能力和市场需求直接满足能力三个维度为切入点设计12项指标,选取718个样本2018年的数据进行分析得出如下结论:高职院校产教融合已推进到主要领域并取得一定成效,但是绩效的整体水平尚待提升,此外绩效的不均衡性也逐步凸显。高职院校产教融合绩效的改进需要政策引导、运行优化以及市场驱动等多重路径的共同作用。本研究对高职院校的高水平建设以及本科院校的应用型转型都具有启发意义。  相似文献
