Mural paintings hold significant historical information and possess substantial artistic and cultural ***, murals are inevitably damaged by natural environmental factors such as wind and sunlight, as well as by human activities. For this reason, the study of damaged areas is crucial formural restoration. These damaged regions differ significantly from undamaged areas and can be considered abnormal targets. Traditional manual visual processing lacks strong characterization capabilities and is prone to omissions and false detections. Hyperspectral imaging can reflect the material properties more effectively than visual characterization methods. Thus, this study employs hyperspectral imaging to obtain mural information and proposes a mural anomaly detection algorithm based on a hyperspectral multi-scale residual attention network (HM-MRANet). The innovations of this paper include: (1) Constructing mural painting hyperspectral datasets. (2) Proposing a multi-scale residual spectral-spatial feature extraction module based on a 3D CNN (Convolutional Neural Networks) network to better capture multiscale information and improve performance on small-sample hyperspectral datasets. (3) Proposing the Enhanced Residual Attention Module (ERAM) to address the feature redundancy problem, enhance the network's feature discrimination ability, and further improve abnormal area detection accuracy. The experimental results show that theAUC(AreaUnderCurve), Specificity, andAccuracy of this paper's algorithmreach 85.42%, 88.84%, and 87.65%, respectively, on this dataset. These results represent improvements of 3.07%, 1.11% and 2.68% compared to the SSRN algorithm, demonstrating the effectiveness of this method for mural anomaly detection. © 2024 The Authors.

“课程思政”是高校思想政治教育在时空交织中的逻辑延展,是课程发展中生成的新的结构性要素。课堂是“课程思政”落地落实的“主渠道”和“主阵地”,而课堂结构是“课程思政”从理念到实践的逻辑中介。吉登斯的结构化理论因赋予结构与行动之间关系的新解释并构建了具有内在逻辑的有机理论系统而彰显其独特性和影响性。鉴于这一视角研究认为“课程思政”课堂结构是课堂教学行动的结果和媒介,它是由以使动性和制约性“二重”属性为逻辑前提、以课堂行动者及其能动作用为逻辑基础、以课堂规则和课堂资源为逻辑展开等主要要素及其相互关系所生成的具有内在逻辑的有机系统。通过对12所一流大学及其13门课程教案文本的分析发现,“课程思政”课堂结构生成的现实困囿包括课堂行动者的角色障碍、课堂规则的症结和课堂资源的瓶颈,而其实践路径应围绕重塑课堂行动者的角色、健全课堂规则和优化课堂资源的逻辑进路开展。

Visible Light-Induced Photocatalysis:Self-Fenton Degradation of p-CIPhOH Over Graphitic Carbon Nitride by a Polyethylenimine Bifunctional Catalyst

Deep degradation of organic pollutants by sunlight-induced coupled photocatalytic and Fenton (photo-Fenton) reactions is of immense importance for water purification. In this work, we report a novel bifunctional catalyst (Fe-PEI-CN) by codoping graphitic carbon nitride (CN) with polyethyleneimine ethoxylated (PEI) and Fe species, which demonstrated high activity during p-chlorophenol (p-ClPhOH) degradation via H_(2)O_(2) from the photocatalytic process. The relationship between the catalytic efficiency and the structure was explored using diff erent characterization methods. The Fe modification of CN was achieved through Fe-N coordination, which ensured high dispersion of Fe species and strong stability against leaching during liquid- phase reactions. The Fe modification initiated the Fenton reaction by activating H_(2)O_(2) into ·OH radicals for deep degradation of p-ClPhOH. In addition, it eff ectively promoted light absorption and photoelectron-hole (e-h ^(+) ) separation, corresponding to improved photocatalytic activity. On the other hand, PEI could significantly improve the ability of CN to generate H_(2)O_(2) through visible light photocatalysis. The maximum H_(2)O_(2) yield reached up to 102.6 μmol/L, which was 22 times higher than that of primitive CN. The cooperation of photocatalysis and the self-Fenton reaction has led to high-activity mineralizing organic pollutants with strong durability, indicating good potential for practical application in wastewater treatment.

交叉学科是高校学科发展的重要趋势和培养创新型人才的重要通道。而资源是交叉学科发展的重要保障,从资源依赖理论视角出发,有助于深入理解高校交叉学科发展的资源依赖及路径。相较于成熟的传统独立学科而言,新兴的交叉学科兼具两个层次的外部环境,且对资源的需求与依赖更为显著。主要表现为对源学科院系和学校层面组成的内层外部环境与政府、社会和企业组成的外层外部环境有形和无形的资源依赖。有形资源包括资金、人力、空间、设施设备、生源、就业岗位资源,无形资源包括制度、权力、文化、政策法律、公信力、信息和技术资源。基于此梳理导向,高校交叉学科发展的路径既要坚持凝练特色和内涵式发展、坚持问题解决和需求导向及遵循学科知识发展的逻辑规律;也要创建交叉学科发展的组织、完善交叉学科发展的制度、搭建交叉学科发展的平台及培育交叉学科发展的文化。

人才引进政策具有重要的价值导向作用,“双一流”建设背景下高校都将人才引进作为促进发展的重要战略行动。通过对部属师范高校引才政策文本进行分析发现,其在青年人才引进中具有优待“人才称号”、注重荣誉和科研能力、重视“海归”背景、偏向高学历、引才成本逐渐提高及旨在为实现“双一流”建设目标服务等共性特征。而引才政策中可能存在的非理性因素容易造成以下问题:过于热衷按“人才称号”选才易使学校教育的原生态受到挑战;过分注重青年人才的科研能力会使“轻教学”之风更加盛行;过度差别化待遇引才不利于高等教育可持续发展;非正常的“人才崇洋”必然会使人才流动市场秩序受到影响。鉴于此,应加强人才引进的科学规划,防范“双一流”政策的负面驱动;坚持科学的人才引进观,构建灵活多样的选才机制;遵循学科发展逻辑,实施差异化的人才引进评价体系;转变人才引进模式,建设人才引进的“软环境”。
