当下我国师范教育改革进入了以产出导向为改革理念的新阶段,即以师范生的学习结果和能力表现来评价师范教育培养质量。本研究突破在师范教育阶段内讨论师范生水平的局限,采用问卷调查和访谈调查法,以毕业后任教1个月的新教师为研究对象,通过新教师自评和老教师他评的对比,呈现师范毕业生的职业能力水平与存在的主要问题。再结合新教师在真实教育情境中的适应性和对在学阶段所接受的师范教育课程的满意度评价,逆向审视师范教育课程存在的问题。以“服务终端”的理念进行课程设置、嵌入前沿属性优化课程教学、数字技术支持“具身拟态”提高实训效果、创设“人人交往”机会消解人机互动带来的沟通弱化等,以推动师范教育的课程改革。

尘封百余年的文献史料中隐藏着一个有关武汉大学筹办的重要史实,即在国立武汉大学成立之前,武汉大学校名即已被先期使用,并有过近20年的三段倡办经历。第一段经历始于清末,源自英美传教士提出的“联合大学建议”,并在选址武汉后引出“武汉大学计划”,但终因经费筹措未果而宣告中止;第二段经历始于武昌起义之后,一批辛亥革命志士为了纪念武昌首义之功,倡议国人自己“设立武汉大学”,后因经费不足而最终未能如愿,但却促成了被作为武汉大学基础而先行开办的国立武昌商业专门学校的诞生;第三段经历起自国立武昌商业专门学校开办之后,由北洋政府鄂籍要员黎元洪等接续筹办武汉大学,曾大张旗鼓地掀起过不小的筹办高潮,其间一度传闻黎元洪将校名更改为江汉大学,并最终留下遗嘱而由其子给国立武汉大学捐款建造了一座现代体育馆。

算法感知是对批判性算法控制研究范式的重要突破,其强调普通用户在算法情境下通过非专业知识来感知算法、理解算法、认识算法,这种基于算法情境的主观感知具有引导和影响后续反馈的潜能。但目前对算法感知及反馈行为关系的研究以“工具性算法”为理念展开,并未从“情境性算法”的分析逻辑对其深层机制进行深度挖掘,研究尝试对此给予补充。以2021年出台的“双减”政策等内容为例,以情境性算法为分析框架,以情景式APP原型为展示场景,探讨用户浏览APP时产生的算法感知及其对反馈行为的影响机制。通过实证分析,提出算法感知影响反馈的三条路径:页面布局影响反馈,既定算法认知影响反馈,算法存在感知影响反馈。在特定情境下,页面布局的影响是基础性的;既定算法认知中的算法运用程度、算法APP的信任、算法喜爱、算法推荐信息容忍度、算法能力等不同程度地影响反馈;算法存在感知在特定情境下正向影响反馈,甚至其还会消解页面布局、既定算法认知对反馈的影响。

Dear Editor,Type 2 diabetes mellitus (T2DM) has been identified as a risk factor for increased severity in acute pancreatitis (AP)(Mikóet al,2018).However,to date,no studies have simultaneously included healthy individuals,T2DM patients,and AP patients to investigate which diabetes-associated metabolites are linked to AP severity.

Optoelectronics Letters 2025年

作者： ZHAO yan LIN Maohua DU Shengzhi TONG Jigang LIU Bin HAN Fangfang School of Electrical Engineering and Automation， Tianjin University of Technology Tianjin Key Laboratory for Control Theory and Applications in Complicated Systems Department of Electrical Engineering， Tshwane University of Technology

In order to identify the tilt direction of the self-mixing interference (SMI) signals under weak feedback regime interfered by noise， a deep learning method is proposed. The one-dimensional U-Net (1D U-Net) neural network can discriminate the direction of self-mixing fringes accurately and quickly. For experimental SMI signals， the 1D U-Net can be used for discriminant direction after a one-step normalization. Simulation and experimental results show that the proposed method is suitable for SMI signals with noise within the whole weak feedback regime， and can maintain a high discrimination accuracy for signals interfered by 5dB noise. Combined with fringe counting method， accurate and rapid SMI signal displacement reconstruction can be realized.

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.
