乡村振兴背景下农村基本公共服务与多维贫困的时空耦合特征研究

村级尺度上探索农村基本公共服务与区域贫困之间的关联特征以及二者耦合作用机理,是实现精准扶贫与乡村振兴战略有机结合的重要一环。本文分别建立农村基本公共服务和多维贫困综合发展监测模型,结合时空探索性分析和耦合协调分析方法,综合揭示两者的时空发展分布特征及其耦合关联关系。2015—2018年研究区内58个行政村的实证结果表明：①研究区内农村基本公共服务的发展呈中段高、南北段低的空间非均衡性分布,整体发展差异呈缩小趋势;②研究区内贫困村的多维贫困状况在空间分布上呈现出中北段地区贫困程度较轻、南段贫困程度较深的格局;③农村基本公共服务与多维贫困存在空间负相关性关联与明显耦合,且自实施乡村振兴战略以来,贫困村多转为同步型发展。研究结果可为现阶段乡村振兴战略的实施提供科学的决策依据和参考。     

巴马盘阳河流域季节性移民社区类型与形成机理

季节性移民聚居现象受到西方学术界的极大关注,而我国鲜有研究。采用观察法和访谈法,对巴马盘阳河流域"一地多类"的季节性移民社区的形成过程、类型特征与作用机理进行归纳与揭示。研究表明：①季节性移民社区演变历经萌芽、快速参与和转型发展三个阶段,社区人口结构、聚居空间、经济业态、景观设施及人文氛围在不同时期呈现出不同的特征;②季节性移民社区形态存在差异,可以归类为交融性社区、优势性社区,共享性社区,纯粹性社区。③季节性移民社区是差异化的"美好生活"需求、独特的长寿资源及乡村生活环境、外来商业资本、地方政府调控和利益共生等"五力驱动"的结果,不同发展阶段其主导动力和作用方式存在差异。     

Chemical and Microscopic Study of Masonry Mortar in Ancient Pagodas in East China

Ancient mortars played a crucial role in the construction of historical architectures due to their physical and chemical compatibility with traditional building materials such as stones and bricks. Therefore, the analysis and optimization of the ancient mortar formula are significant in the restoration and preservation of historical sites. In this work, 20 mortar samples selected from five ancient stone pagodas in Zhejiang Province, China, were analyzed. The results showed that mud, lime-soil mortar, lime-sand mortar, and lime-gypsum mortar were used as binders in these pagodas. The Ca(OH)₂/aggregate ratio ranging from 0.3 to 2.7 was usually used to prepare lime mortar. Protein and polysaccharide were also found in some samples.     

让材料自己说话——浅论当前历史传记写作的一种趋势

《陈寅恪的最后二十年》、《顾颉刚和他的弟子们》、《束星北档案》等著作,代表了当前历史传记写作的一种趋势。《陈寅恪的最后二十年》的文本近似历史叙事散文;《顾颉刚和他的弟子们》的文本更接近史学论文;而《束星北档案》则类同电视记录片的文稿。这些著作共有的特点是:在修撰方式上,大量运用了第一手材料;在文本风格上,力求作品深入浅出、雅俗共赏;在写作理念上,坚持真实第一,尊重历史。这一趋势非常值得重视。     

Neighbourhood food environments revisited: When food deserts meet food swamps

This study uses service area–based coverage and various count regression methods to assess neighbourhood-level healthy and unhealthy food environments, and food access associated with different socio-economic groups in Edmonton, Canada. We identify three types of vulnerable neighbourhoods according to different food environments: food deserts (i.e., neighbourhoods lack sufficient access to healthy foods); food swamps (i.e., neighbourhoods have excess access to unhealthy foods); and those with overlaps of food swamps and food deserts. We also identify neighbourhoods with superior access to healthy foods (i.e., food oases). Additionally, our results from regression analyses indicate: (1) child population is negatively associated with both healthy and unhealthy food resources; (2) good access to public transportation is associated with good coverage of all healthy food outlets and convenience stores; and (3) deprived neighbourhoods with higher percentages of minority populations have better coverage of both healthy and unhealthy foods in general. The results from this study can help the City of Edmonton identify the key neighbourhoods with high potential for local business and the hotspot neighbourhoods that require particular support. Tailored strategies are proposed to effectively and efficiently improve food environments with limited resources.     

经济行为与环境变化:清前期台湾野生鹿消失探析

鹿曾经是台湾数量最庞大的野生动物群之一。明末以来,随着台湾贸易交流的活跃,鹿成为大宗出口商品,土著居民由原先捕鹿作为民生用品逐渐发展至为市场服务;清前期大陆移民入台的农业垦殖又破坏了鹿原有的生态环境。人类经济行为引发的环境变化,最终导致了野生鹿在台湾渐趋消失。

宋代江南地区慈善事业研究

宋代江南地区社会慈善事业的发达,集中体现在官方慈善事业的繁荣和民间慈善事业的勃兴两个方面.官方通过兴建慈善机构、设置慈善粮仓、实施应急救济等手段来推动慈善事业的发展.民间则通过成立慈善组织、实施族内济助、自发捐资行善等方式来促进慈善事业的进步.宋代江南地区的慈善事业具有机构设置早、规模大、设施全、济助对象多、慈善活动制度化等特点.政府高度重视、经济高度发达、古代慈善思想的影响以及社会各界人士的积极参与等,是宋代江南地区社会慈善事业迅速发展的主要原因.     

兔儿爷：从兔神和儿童玩具到民间艺术品

在20世纪50年代初之前兔儿爷在北京是一个流行的节日物件儿,那时候这个泥塑的兔神在中秋节是孩子们必备的玩具,同时也是中秋拜月的偶像,而今兔儿爷是民间艺术品,在旅游纪念品和民间工艺品商店还有春节庙会上都可以买到。兔儿爷里的“儿”是北京话里的儿化音,并没有实际的意思;“爷”在这里是神的意思。
