生物饵料培养课程教学改革的探索与实践

介绍了“激发学生学习兴趣—优化课堂理论教学—强化实验教学”模式在生物饵料培养课程教学中的探索与实践。提出增强教学的趣味性、改革课程考核方法、合理安排实验课顺序及加强学生实验操作能力的培养等途径改革教学方法。通过问卷对此教学模式进行调查,结果表明生物饵料培养的教学改革取得较好的效果。     

人居环境治理视域下地质文化村建设路径研究

地质文化村是脱贫攻坚和乡村振兴背景下衍生出的乡村地质遗迹保护和开发利用相结合的新概念,目前正在全国多地推广设立,现有研究主要集中在内涵分析和规划设计方面,其具体建设过程中缺乏科学的路径参考。本研究从乡村人居环境治理的视角出发,首先,在讨论的基础上将地质文化村归类于人居环境“景区化治理”的一种形式;其次,基于扎根理论的研究方法将筛选的39篇“人居环境治理”主题文献作为研究资料,利用NVivo11对文献内容进行编码,构建了“人居环境治理”主题分析框架;最后,在归纳和借鉴人居环境领域研究成果的基础上,从“响应国家战略”、“建设思路”、“保障措施”“建设手段”四个方面提出了地质文化村的建设路径。     

我国地质文化村（镇）空间分布特征及影响因素研究

地质文化村（镇）是地质文化科普的重要窗口,也是所在区域经济社会发展的重要依托,对其空间分布特征及影响因素的研究对我国地质文化村（镇）的进一步评定和可持续发展具有重要意义。运用最邻近指数、不平衡指数、核密度分析和地理探测器方法,对我国50个地质文化村（镇）的空间分布特征及其影响因素进行研究,研究表明：①地质文化村（镇）的空间分布类型为随机分布型;②各省（市、区）地质文化村（镇）数量差异明显,空间分布不均衡,呈“东多西少”格局;③地质文化村（镇）形成1个高密度核心区、2个次高密度集聚区、1条核心延长带;④影响我国地质文化村（镇）空间分布格局的因素由特色地质资源、自然条件以及社会经济与人文资源3个一级指标构成,其中社会经济与人文资源对地质文化村（镇）空间分布影响最大且效果显著。在今后地质文化村（镇）的评定建设中,应加强中西部地区地质文化村（镇）的建设和申报;适当给予中西部地区地质文化村（镇）评定倾斜;加大地质文化村（镇）宣传力度;充分发掘地质特色及民俗文化,加强地质文化村（镇）与文化的融合。     

新文化地理学的理论统一性与话题多样性

新文化地理学起源于20世纪80年代,是对传统文化地理学研究范式的激进反思甚至颠覆。首先,新文化地理学具有理论基础的统一性。其反对伯克利学派"超有机体"的文化观,认为"文化"并非具象的"物体",而是在特定的社会情景或社会关系之下由社会群体自下而上地建构或生产的。自然、景观、地方、空间等地理学要素也并非"文化"被动的表达或容器,而是建构意义与价值系统的关键维度。其次,新文化地理学具有研究话题的多样性。这种多样性不应该被简单理解为研究视角的分散性或破碎性,而是新文化地理学的文化观带来的必然结果。新文化地理学关注草根群体自下而上的文化实践、不同群体与不同尺度的文化事项、以及瞬息万变的日常生活经验。因此,这极大地拓展了其研究话题的广度。目前,中国地理学中有关文化的研究还处在比较边缘化的位置,但现代中国社会的高速变迁迫切地要求文化地理学者从文化的社会性与空间性出发,探讨社会成员赋予自然、景观、地方、空间等地理学要素的文化意义,以及文化这一维度在经济地理学、城市地理学等研究中的重要作用。     

苏轼诗歌与北宋文化的议论精神和淡雅精神

北宋文化吸纳了前此数千年的历史积淀 ,而皮毛落尽 ,精神独存 ,不仅各个文化领域、各类文化形式、各种雅俗文化百花齐放 ,更以独树一帜的北宋文化精神卓然自立。苏轼的诗歌正是在北宋这一特定历史时期的文化背景下孕育成长起来的。作为中国传统文化最具典型性的“文人”代表 ,苏轼通过其二千七百余首包赡丰富、变化万状的诗作 ,展现出了一幅北宋文化绚丽多彩的历时性的“清明上河图”。尤其引起我们注意的是 ,北宋文化精神中最为突出的两个方面———议论精神和淡雅精神 ,对苏轼诗歌产生了更为直接、更为深刻的影响 ,而苏诗的议论化和崇雅尚淡倾向又更为突出、更为集中、更为典型地代表了北宋文化的议论精神和淡雅精神     

REGIONAL VARIATIONS IN DENOMINATIONAL SWITCHING AMONG WHITE PROTESTANTS*

This study examines the hypothesis that the determinants of denominational switching vary regionally among white American Protestants. Data for the analysis are taken from the National Opinion Research Center's General Social Survey for 1974 through 1984. Using logistic regression, the analysis compares the determinants of switching among respondents residing in the nine Census regions of the U.S. Results reveal significant regional differences in the determinants of switching, especially in the effects of conversion, childhood affiliation and interdenominational marriage.
