基于标准病例的案例教学法在普外科见习教学中的应用探讨

目的:探讨基于标准病例(SP)的案例教学法(CBL)在普外科见习教学中的应用效果。方法:选取2014年6月至2015年6月我院见习的五年制临床本科医学生共112人,利用随机数字表的方法将其分为对照组和研究组,两组人数各56人。对研究组采取基于SP的CBL教学法,而对照组则使用传统临床带教方法,1个月后对理论、技能进行评价,并对学生和教师的满意进行问卷调查。结果:在技能考核和病例分析方面,研究组学生的得分显著高于对照组(P0.05),理论成绩无明显差异(P0.05)。对学生满意度的调查中,在"课堂气氛活跃"、"对学习兴趣的激发"、"利于理论与实践结合"以及"有利于形成正确临床思维"四个方面,研究组的满意度显著高于对照组(P0.05)。在对教师满意度调查中,认为试验组教学法的效率要高于对照组教学法(P0.05),而在"易实施性"满意度低于对照组教学法(P0.05),在"可操作性"方面差异无统计学意义(P0.05)。结论:与传统教学模式比较,基于SP的CBL教学法具有显著的优势,能更直观的展示某种疾病的特征,使学生通过实践巩固对基础知识的记忆,值得进一步探索并推广。     

Creating the conditions for peacemaking: theories of practice in ethnic conflict resolution

Establishing the conditions for effective intergroup peacemaking is a formidable task in severe ethnic conflicts. Conflict resolution practitioners argue that a critical first step is developing preconditions which convince competing groups that there are opponents to whom it is worth talking, that it is possible to create structural changes conducive to a stable peace, and that an agreement is possible which can meet each side's basic concerns and needs. This article compares six theories of practice of ethnic conflict resolution: community relations, principled negotiation; human needs; psychoanalytically rooted identity; intercultural miscommunications and conflict transformation, examining how each understands ethnic conflict; the goals it articulates; the effects of good practice on participants in interventions; the mechanisms by which the project achieves its impact; and the dynamics of transfer affecting the course of a wider conflict. It is argued that clearer articulation of these assumptions will improve both theory and practice in the search for settlements to severe ethnic conflict.

Narratives of success among Irish and African Caribbean migrants

This paper compares the narratives of two men in midlife who migrated to the UK from Ireland and from the Caribbean as children, in the middle of the last century. We examine how success is narrated over the life course to show how migrants’ positioning of themselves differs from the ways in which they are positioned by outsiders, including in policy and public discourse. We conclude that while outsider narratives often polarise success and failure, insider understandings of success are dynamic and culturally and historically situated.     

细胞生物学教学改革初探

细胞生物学是生命科学专业的一门必修的专业基础课,占有非常重要的地位。鉴于我院细胞生物学课程课时安排少、实验少、与已修课程有重复内容、相关科学前沿知识不能及时更新、"填鸭式"教学模式和传统的以"讲"为主的教学方法等严重影响该课程教学质量的教学现状,提出了从课程结构体系、课程教学内容,教学方法及考核方式等方面的一系列改革探究,课程结构体系方面由专业任选课变更为专业基础课,适当增加了理论课时;从课程内容来看,取缔与已修课程的重复内容,适当补充最新科研动态、介绍相关的诺贝尔奖,积极鼓励学生参与教师的相关科研项目和申报大学生科研创新活动项目,培养学生的科研创新能力;从教学模式来看,教师要积极利用图文并茂的多媒体教学、适时放映学生喜欢看的相关电教视频、课堂上多以讨论和提问的方式教学;考核采用平时成绩加期末成绩的方式,不断提高教学效率和课堂管理水平,促进教学质量的提高。     

欧洲云杉的扦插基质选择和穗条效应研究

以欧洲云杉6年生母树为采穗母株,系统研究了不同插穗条件对生根和幼苗生长的响应,同时观测了网袋容器基质配比对扦插幼苗生长的影响.结果表明:扦插后20 d愈伤组织开始形成,37 d时根尖开始出现,50～65 d是生根的高峰期和根系发育期,65 d时扦插苗根系基本形成.不同基质对欧洲云杉插穗生根率影响达到极显著水平,1份泥炭...

Recent novel approaches for population genomics data analysis

Next‐generation sequencing (NGS) technology is revolutionizing the fields of population genetics, molecular ecology and conservation biology. But it can be challenging for researchers to learn the new and rapidly evolving techniques required to use NGS data. A recent workshop entitled ‘Population Genomic Data Analysis’ was held to provide training in conceptual and practical aspects of data production and analysis for population genomics, with an emphasis on NGS data analysis. This workshop brought together 16 instructors who were experts in the field of population genomics and 31 student participants. Instructors provided helpful and often entertaining advice regarding how to choose and use a NGS method for a given research question, and regarding critical aspects of NGS data production and analysis such as library preparation, filtering to remove sequencing errors and outlier loci, and genotype calling. In addition, instructors provided general advice about how to approach population genomics data analysis and how to build a career in science. The overarching messages of the workshop were that NGS data analysis should be approached with a keen understanding of the theoretical models underlying the analyses, and with analyses tailored to each research question and project. When analysed carefully, NGS data provide extremely powerful tools for answering crucial questions in disciplines ranging from evolution and ecology to conservation and agriculture, including questions that could not be answered prior to the development of NGS technology.
