Relational identities and intergenerational learning in an undergraduate critical food studies course

Abstract

Environmental education (EE) scholars view intergenerational learning as a means to influence adult understandings of and relationships with the environment. Yet EE researchers have studied intergenerational learning in a limited fashion, with no emphasis on its role in higher education. The purpose of this article is to use feminist posthumanist theories to broadly explore intergenerational learning in critical food studies courses taught at the university level. We rely primarily on student coursework and post-course interviews as data sources that convey student perceptions of interactions with their families and the natural world, demonstrating how students develop relational identities shaped by personal experience as well as experiences in the course. To conclude, we discuss both the limitations and implications of this research for the field of EE.     

基于Internet环境的毕业设计初探

毕业设计(论文)是完成专业培养目标的一个重要教学环节。构建基于Internet环境的毕业设计模式,其目的主要是为学生提供丰富的毕业设计资源,为毕业设计小组成员之间、指导教师与学生之间提供实时和非实时的交互工具,充分利用Internet工具为学生的毕业设计工作服务。     

民国时期社会教育师资的培养方式及其特征

社会教育的师资培养与学校教育相比,有许多自身的特点。民国时期社会教育师资培养主要采用设立学制体系内的学校教育和开办短期培训班两种方式,具有培养方式和途径的多样化、生源地域化、注重课程设置专业性和师范性以及师资培养全面性等明显特征。探寻民国时期社会教育师资的培养方式及其特征,不仅有助于深入了解社会教育发展的历史,也可以为今天成人教育、社会教育师资培养提供有益的思考。     

"时代精神"与"以大为美":闻一多辞赋评论二题

闻一多先生是“现当代赋学研究史上不专治赋学而对赋有独到认识”的批评家。他在研究《楚辞.天问》的同时论及汉赋,并且提出了关于辞赋的重要观点:研究辞赋作品要明了并探讨其“时代背景”和“共同精神”;《天问》和汉赋的伟大之处就在于它们是“以大为美”,故而汉赋作品要以读《天问》的观点和从“以大为美”的角度去欣赏评价。     

Dimensions of academic interest among undergraduate students: passion,confidence, aspiration and self-expression

We investigated psychological dimensions of academic interest among undergraduate students (N = 325) using a global academic interest scale. The scale was administered together with measures of academic performance, educational aspiration, career planning, goal setting, life satisfaction, attitudes towards leisure, personality and value. Exploratory factor analyses revealed four dimensions of academic interest: passion for learning, confidence in the future, career aspiration and self-expression. All four dimensions were significantly related to career planning, goal setting and life satisfaction. On the other hand, specific pairings of significant relationships were found between different dimensions of academic interest and personality and value, suggesting that students with different personalities and different sets of values are likely to appreciate and respond to different aspects of academic interest. We conclude with implications for research on academic interest development across a more diverse range of age groups.     

论现代电影中的“封闭空间”

＂封闭空间＂是现代电影空间中常见且重要的类型。＂封闭空间＂更加注重叙事的功能,主要有三个方面的特性：其一,封闭性与开放性,二者相辅相成;其二,独特的时空关系,其中空间表征法更好地彰显了人物的性格及其命运;其三,它的符号特征,特别是象征和隐喻的作用以及诸多空间意象的叙事功能。＂封闭空间＂成为现代电影重要的表现舞台,其中燃烧着电影的激情、任想象驰骋。它在彰显自身艺术魅力的同时,也暗含着一种诗意的境界,产生一种从本质上可以打动人心的强烈情感效果。     

乌索酸固体分散体含量测定方法的研究

目的:建立反相高效液相色谱法测定固体分散体中乌索酸的含量,并检测其色谱峰的纯度。方法:色谱柱为Nova-Pak C18(3.9×150 mm,4μm),流动相为甲醇-水(88∶12),流速1.0 mL/min,检测波长210nm,柱温25℃。结果:乌索酸在0.86~14.62μg范围内线性关系良好(r=0.9995),平均回收率为99.0%,检出限0.2 mg/L(3σ)。结论:方法简便,准确,重现性好,线性范围宽,适用于乌索酸制剂的质量评价。     

中学生课外补习时间投入对学业成绩的影响——基于PISA2015我国四省市数据的实证研究

基于PISA2015中国四省市数据,采用多层线性模型,研究中学生各科课外补习时间投入对学业成绩的影响效应.研究发现:课外补习时间与学业成绩之间存在先降后升的非线性关系,表明学科补习具有门槛效应,当补习时间超出某个阈值,学业成绩才会出现质的提升;数学补习时间投入差异扩大了不同家庭背景学生间数学成绩的差距,会造成教育结果的不均等;校内课程时间对学生成绩的影响呈先升后降的非线性关系,相较于补习时间,校内课程时间能更有效地提升学生成绩.因此,中学生及家长应基于实际的补习需求,合理投入补习时间;学校应保证学生校内课程学习时间,发挥学校教育的主导作用;政府应重视课外补习对教育公平的冲击,加强对校外培训机构的监管,还要为经济困难家庭学生提供必要的课外补习机会,缩小因课外补习带来的教育结果不均等,努力促进校内外教育公平.     

Intelligent Control Scheme of Engineering Machinery of Cluster Hybrid System

In a hybrid system, the subsystems with discrete dynamics play a central role in a hybrid system. In the course of engineering machinery of cluster construction, the discrete control law is hard to obtain because the construction environment is complex and there exist many affecting factors. In this paper, hierarchically intelligent control, expert control and fuzzy control are introduced into the discrete subsystems of engineering machinery of cluster hybrid system, so as to rebuild the hybrid system and make the discrete control law easily and effectively obtained. The structures,reasoning mechanism and arithmetic of intelligent control are replanted to discrete dynamic, continuous process and the interface of the hybrid system. The structures of three types of intelligent hybrid system are presented and the human experiences summarized from engineering machinery of cluster are taken into account.     

论唐宋诗词的时空结构形态

时间和空间是一切事物同时也是古典诗词得以存在的基本形式。由此出发，章将唐宋诗词里利用时间和空间关系构章谋篇的样式归纳为三种，即时空平行、时空错综、时空隐喻；这不失为进一步透析古诗词章法意境的一个角度。
