基于三维场景的地质遗迹景观精细化遥感解译

针对目前复杂地形区地貌景观地质遗迹形态特征调查困难的问题,提出应用倾斜摄影测量技术构建三维模型以提高调查精度.本文以流纹质火山岩地貌景观调查为例,以仙居神仙居国家地质公园为研究区开展研究,首次进行了复杂地貌区大范围倾斜摄影测量与基于三维场景的地质遗迹景观精细化遥感解译研究.首先应用倾斜摄影测量技术开展研究区测量获取高精度三维地形和遥感影像数据,并建立研究区地貌三维实景模型;其次基于三维场景开展典型流纹质火山岩地貌景观精细化遥感解译,对复杂地貌单体形态特征进行精细化量算,对纵向崖壁等微地貌特征进行精细化解译,获取地貌景观单体精确形态特征参数和崖壁微地貌特征信息,定量化定义了峰、嶂、谷等典型流纹质火山岩地貌类型.本文成果对其他类型复杂地貌区地质遗迹调查具有参考意义.     

“雨课堂+QQ”的综合日语混合式教学研究

混合式教学模式是教育现代化的内在要求。针对传统教学中存在的“以教为主”“缺乏互动”“学情不清”的问题,结合雨课堂与QQ对综合日语Ⅰ~Ⅳ开展了混合式教学改革,基本实现了“以学为主”“实时互动”“明确学情”的有效转向。问卷调查结果表明,改革使学生的学习主体性确立,日语能力提高,专业学习自信增强。     

大学图书馆面向年轻馆员的人才培养策略探析——以上海交通大学图书馆为例

运用恰当、有效的策略吸引、培养和留住年轻馆员,是高校图书馆保持核心竞争力的关键.近十年来,就如何建设一支高素质的年轻馆员队伍,上海交通大学图书馆在人才招聘、岗位聘任、薪酬管理、职务晋升、馆员培训、国际交流和考核评估等方面进行了系统性的探索,并就"十四五"期间大学图书馆如何培养年轻馆员人才队伍进行了思考.     

图书馆核心价值浅论

核心价值研究是图书馆服务转型过程中绕不开的热点问题。文化权利,知识自由,开放、平等、包容、隐私等主流观点更多倾向价值观念而非价值本身,难以达成行业共识。文章从价值哲学视角分析图书馆价值及其主要价值关系:馆员、读者与文献信息三者之间的推广关系与阅读关系共同构成图书馆阅读推广体系。文献信息资源、读者资源和馆员队伍共同构成图书馆核心竞争力。阅读推广从“满足阅读”到“推进阅读”、从“被动服务”到“主动服务”,发挥图书馆在全民阅读中的主体地位与引领作用,成为图书馆核心价值。     

以科技竞赛为核心搭建多维实践教学平台的研究

实践教学是巩固理论知识以及提升大学生综合技能素质的重要环节。要针对物联网专业学生培养过程中实践教学平台存在的问题,结合本科院校物联网专业建设特点,以科技竞赛为核心驱动力,在"一个核心、两个平台、三个建设、多方合作"的指导原则下,搭建适合物联网专业的多维实践教学平台。要通过实践教学平台全面辐射整个实践教学环节,培养出优秀的具有市场竞争力的大学生,满足社会对物联网专业人才不断扩大的需求。     

论hyponymy等术语命名及翻译的认知逻辑理据

hyponymy作为重要的语义学术语,不仅自身较为复杂,而且关涉到meronymy,taxonomy等概念。更为关键的是,这些术语之所以获得各自现行的称谓形式,其背后一定存在着相应的缘由或动因,而学界对此关注不够,如时下的一些不当翻译恰恰是由于对相关术语命名理据缺乏充分认识导致的。鉴于此,依据认知语言学"基本层次范畴理论"和逻辑语言学中的对称及非对称关系类型等思想,分别探讨相关术语命名的认知理据及其翻译的逻辑理据。这对于其他语言学术语渊源探究具有借鉴价值和启示意义。     

论教师课程执行力的内涵、表征及功能

课程是实现教育方针政策的基本载体。教师作为课程执行的直接责任人,其执行水平和效果是反映课程场域中立德树人实现情况的重要指标。教师课程执行力的内涵可概括为“五度”,即教师执行课程的法度、教师执行课程的尺度、教师执行课程的刚度、教师执行课程的速度、教师执行课程的效度。教师课程执行力具有“知力”“能力”“行力”“效力”四大基本表征。教师课程执行力的发挥对正确认识课程、发展课程、以及实现课程育人等,都具有重要意义。

Teaching About Love and Practicing Feminist Pedagogy in a College Classroom

Being a feminist teacher, working on gender equity education, including teaching, reading, writing, and doing research on this topic, has become a commitment for me. I have frequently reflected my teaching practices and occasionally found new teaching strategies in the classroom. I always try to bring new topics or issues into the classroom in order to raise students' gender consciousness. I also try hard to figure out what can be done to empower students. Teaching about love is one way I use to empower college students in the gender course. This article is about my teaching experiences. I intend to discuss the teaching strategies, particularly focusing on the topic of love, to explore the possible ways of practicing feminist pedagogy.     

Effects of hypoxic exercise training on microRNA expression and lipid metabolism in obese rat livers

To investigate the effects of hypoxic exercise training on microRNA (miRNA) expression and the role of miRNA expression in regulating lipid metabolism, 20 dietary-induced obese SD rats were divided into a normoxic sedentary group (N, n=10) and a hypoxic exercise training group (H, n=10). After four weeks, measurements were taken of body weight, body length, fat mass, serum lipid concentration, miRNAs differentially expressed in rat liver, and gene and protein expression levels of peroxisome proliferator activated receptor α (PPARα), fatty acid synthetase (FAS), and carnitine palmitoyl transferase 1A (CPT1A) in rat liver. Body weight, Lee’s index, fat mass, fat/weight ratio, and serum levels of total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) were all significantly lower in the H group than in the N group (P<0.01). Six miRNAs expressed significantly differently in the liver (P<0.05). Specifically, expression levels of miR-378b were significantly lower in the H group than in the N group (P<0.05). Compared with the normoxic sedentary group, hypoxic exercise training resulted in a lower ratio of FAS mRNA to CPT1A mRNA (P<0.05), as well as lower CPT1A protein levels (P<0.01), while a higher ratio of FAS to CPT1A protein levels (P<0.01) was observed. In conclusion, hypoxic training may elevate the resistance of high fat diet induced obesity in rats by reducing the expression of miR-378b, and decrease the fatty acid mitochondrial oxidation in obese rat livers by decreasing the protein expression of CPT1A and increasing the protein expression ratio of FAS/CPT1A.
