论马克思主义学院在课程思政改革中的实践价值

课程思政是各高校落实立德树人根本任务,做好思想政治工作的重要举措。当前各高校课程思政改革由理论研究转向实践阶段普遍陷入了瓶颈。究其原因,关键是缺乏主导力量,责任主体不明确。因此,在课程思政改革中充分发挥马克思主义学院的核心地位、主导作用和建设力量,逐渐形成“三位一体”的课程思政改革的实践方案,是实现“三全育人”新格局的关键。     

职业教育“就业导向型”人才培养模式探讨

职业院校普遍存在毕业生就业难的问题,其原因在于职业院校的专业设置不合理、教师队伍素质有待提高、学生实践能力差、缺乏创新意识与合作精神,毕业生数量增长过快也是一个重要因素。构建“就业导向型”人才培养模式,就要科学地进行专业设置及课程设置。加强师资队伍建设,加强就业指导队伍建设,强化实践教学环节,提高学生心理素质。

Distribution of Welding Residual Stress of Mixed Steel U-Rib-Stiffened Plates

To analyze the effects of width and thickness of each composition element of mixed steel U-rib-stiffened plates on the welding residual stress distribution, the distribution of the U-rib and the plate residual stress was calculated using a simplified calculation method. The method involved welding the mixed steel U-rib-stiffened plates for a structure with different sizes and different strength ratios of U-rib to plate. Based on a welding residual stress numerical simulation method validated by the blind hole method test, the distribution law of the mixed steel U-rib stiffened plate was studied. The results showed that the change of plate width has little impact on the welding residual stress and that the ratio of the thicknesses of the plate to U-rib stiffeners, the thickness of the plate, and the thickness of the U-rib has a great influence on the distribution of the welding residual stress. The thickness of plate and steel strength also greatly influenced the distribution width of the residual tensile stress. While analyzing the compression capacity of U-rib-stiffened plates, the simplified distribution of welding residual stress was used.     

3D brain glioma segmentation in MRI through integrating multiple densely connected 2D convolutional neural networks

To overcome the computational burden of processing three-dimensional(3 D) medical scans and the lack of spatial information in two-dimensional(2 D) medical scans, a novel segmentation method was proposed that integrates the segmentation results of three densely connected 2 D convolutional neural networks(2 D-CNNs). In order to combine the lowlevel features and high-level features, we added densely connected blocks in the network structure design so that the low-level features will not be missed as the network layer increases during the learning process. Further, in order to resolve the problems of the blurred boundary of the glioma edema area, we superimposed and fused the T2-weighted fluid-attenuated inversion recovery(FLAIR) modal image and the T2-weighted(T2) modal image to enhance the edema section. For the loss function of network training, we improved the cross-entropy loss function to effectively avoid network over-fitting. On the Multimodal Brain Tumor Image Segmentation Challenge(BraTS) datasets, our method achieves dice similarity coefficient values of 0.84,0.82, and 0.83 on the BraTS2018 training; 0.82, 0.85, and 0.83 on the BraTS2018 validation; and 0.81, 0.78, and 0.83 on the BraTS2013 testing in terms of whole tumors, tumor cores, and enhancing cores, respectively. Experimental results showed that the proposed method achieved promising accuracy and fast processing, demonstrating good potential for clinical medicine.     

二语心理词汇中英语动词的组织

通过单词联想测试探讨二语心理词汇中不同词频的英语动词的组织,可以看出低水平二语学习者和高水平二语学习者对于不同词频的动词反应有着明显差异,两组学习者对高频动词的反应均以组合型为主,但是对于低频动词来说,前者的反应以语音为主,而后者的反应仍以组合型为主。因此,不能笼统的认为二语心理词汇的组织是以某一种方式为主,词性、词频以及语言水平等因素都在二语心理词汇的组织中起一定的作用,从而导致二语心理词汇的性质既有语音的又有句法的。
