推进制度创新 提升高校教研室整体教研水平

教研室是高等院校组织完成各项教学和科研任务的基层组织。制度创新有利于充分发挥 教研室在集体备课、新教师培养、集体评卷、教师整体水平提高等方面的作用。     

低频电磁场对大鼠肺组织红外谱影响研究

通过光镜下的组织病理学观察,采用高分辨率的傅里叶变换红外光谱仪,对长期暴露在高场强低频电磁场环境中的大鼠肺组织和对照组大鼠肺组织进行了对比研究,力求从分子水平上揭示暴露组大鼠肺组织和对照组大鼠肺组织的红外吸收光谱存在差别的原因,为进一步探讨高场强低频电磁场造成生物体组织损伤的作用机制提供实验依据。

水库地区路基断面设计与防渗设计

设计水库路基时，应根据水库的运行特点，考虑库水浸泡、渗透、水位升降、渡浪侵袭、水流冲刷、库岸坍塌、水库淤积和地下水壅升引起的湿陷等影响。通过工程实例，分析了造成库区路基病害的原因，从填土造地、渗透稳定、滑坡治理、塌岸防护等综合治理和综合利用的原则出发，探讨了库区新建路基和改造路基的形式及构造。研究了路基本体和地基的渗流计算分析与控制方法，详细阐述了各种路基断面形式、防渗设施布置形式以及路基填料等在不同水位差条件下的适用性和有效性。     

从"断章取义"到"以意逆志"——孟子复原式解释理论的产生与演变

孟子"以意逆志"说历来被公认为中国文论中关于文学解释的最具影响力的理论。尽管学界深谙这一理论的历史意义,却很少有人关注过先前观诗传统对它的影响,后来《毛诗序》对它的彻底改造亦研究不多,正是这些忽略阻碍了我们对其起源及演变的认识。到底是什么样的天才灵感使得孟子将一种倾听理解赋诗或引诗的方法转化成一个以读者为中心的复原式解释理论呢?汉代及以后的注《诗》、评《诗》家是怎样对这一理论加以运用的呢?文章力图对这两个重要问题作出粗浅的解答。     

异型截面环件径向轧制的数值模拟研究

建立了异型截面环件轧制的有限元模型,基于Deform软件模拟分析了环件径向轧制全过程,揭示了芯辊进给速度、主辊转速对主轧制力的影响规律。[HTK]结果表明,环件径向轧制的毛坯结构应与成品结构具有相似性,计算机数值模拟对优化毛坯结构,制定工艺参数,提高轧制效率具有重要的意义。     

《榆林日报》对陕北民歌及陕北音乐文化宣传和报道的版块综合分析

《榆林日报》是榆林市委机关报,它作为陕西北部的地方性的报纸,在其创建多年历史中,对陕北民歌及陕北音乐文化进行了大量的宣传和报道,对榆林民间音乐的传播起到了不可忽视的作用,对榆林地区的广大群众尤其是对榆林青少年的影响是巨大的,更在对陕北民歌等非物质遗产文化的传承与保护方面做出了一定贡献。同时它也在榆林地区特有的文化环境中,形成了自己的地方性特色。本文通过对《榆林日报》进行简单介绍,对其陕北民歌及陕北音乐文化宣传和报道版块的现状、特点、发展的趋势和重要性进行综合分析,并对其特色形成原因进行初步探索,又与其同级别报纸《延安日报》的类似版块进行了对比,最后对存在的问题提出了建议。

Women’s experiences of intrapartum care and recovery in relation to planned caesarean sections: An interview study

Problem and backgroundApproximately one third of women in high-income countries give birth by caesarean section (CS). Better understanding of women’s CS experiences is vital in identifying opportunities to improve women’s experience of care.AimTo identify opportunities for service improvement by investigating Australian women’s experiences of care and recovery when undergoing a planned CS.MethodsQualitative telephone interview study with 33 women who had a planned CS at one of eight Australian hospitals. Semi-structured interviews were conducted to elicit women’s perspectives, experiences and beliefs surrounding their planned CS. Interviews were transcribed verbatim and analysed inductively using NVivo-12.ResultsWomen’s experiences of CS care were mixed. Regarding intrapartum care, many women stated their planned CS was a positive experience compared to a previous emergency CS, but was scarier and more medicalised compared to vaginal birth. CS recovery was viewed more negatively, with women feeling unprepared. They reported disliking how CS recovery restricted their role as a mother, wanting more time in hospital, and greater support and continuity of care.DiscussionWomen reported largely positive intrapartum experiences of planned CS but relatively negative experiences of CS recovery. They wished for time in hospital and support from staff during recovery, and continuity of care.ConclusionBy incorporating shared decision-making antenatally, clinicians can discuss women’s birth expectations with them and better prepare them for their planned CS and recovery.
