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.     

现代仪器分析技术在皮质文物保护中的应用

随着现代科学技术的不断发展,越来越多的仪器分析技术和方法被应用到皮质文物保护领域。分析检测是获取文物病害信息和评估保护效果的重要途径,可以为文物保护修复提供科学依据。文章介绍了表面分析、光谱分析和波谱分析、热分析以及联用技术等现代仪器分析方法和技术的特点和优势,以及它们在皮质文物保护中的应用情况。皮质文物本身蕴含着大量丰富的信息,对皮质文物开展系统全面分析研究,从宏观和微观等不同层面定性和定量研究环境因素对皮质文物物理、化学性质以及微观结构的影响。建立皮质文物检测结果数据库和皮质文物病害标准图库,以及构建皮质文物劣化和病害防治保护效果评价体系是未来研究的主要发展方向和趋势。     

旅游目的地选择行为的收入群体差异——以北京、武汉、西安城镇居民为例

以北京、武汉、西安城镇居民为例,探究旅游目的地选择行为的收入群体差异。研究发现,不同收入群体的旅游目的地选择行为存在明显差异,具体表现在：①不同收入群体的景区到访率均随距离的增加呈e指数衰减,但衰减速率存在收入群体差异,收入越高的群体,到访率距离衰减速率相对越小。②中国城镇居民的国内旅游目的地选择行为具有“距离择近,景点择高,经济择富”的“三择”倾向,但不同收入群体的“三择”程度不同,收入越低的群体,“距离择近,经济择富”的倾向越明显。③不同收入群体到访率空间分异趋势一致,但高到访率空间大小不同,收入越高的群体,高到访率空间越大。④目的地亲景度存在收入群体差异,收入越高的群体,目的地亲景度越高。     

“Catching the Yellow Ghost”: A Case Study of Popular Religious Activities and Social Transformation in Rural North China

This article studies the relationship between local society and social change in rural north China from the late Qing dynasty to the People’s Republic of China period through the activity of “Zhuo huanggui” (literally, “Catching the Yellow Ghost”). “Catching the Yellow Ghost” is a ritual activity in Guyi village, Wu’an county, Hebei province. According to villagers there, “Catching the Yellow Ghost” has been celebrated since the late Qing dynasty. However, due to political pressures in the 1950s, it was not until the 1980s that “Catching the Yellow Ghost” began to be revitalized. Since that time, “Catching the Yellow Ghost” has gained rapid popularity and fame in north China. Through the lens of the “Catching the Yellow Ghost” ritual, this article explores social transformation in China from the late 19th to the early 21st century. By analyzing the continuity and discontinuity of “Catching the Yellow Ghost,” this article offers a new understanding of the relationship between local society and social change in rural north China.     

山地聚落历史人口的重建:以近三百年云南峨山沿河村为例

重建山地聚落人口变化的时空过程对认识历史时期人口发展有重要意义。本文以西南山地聚落沿河村为例,以田野调查资料为主,辅以历史文献和档案,利用估算户数和户均口数的方法重建了沿河村近三百年的人口变化过程。户数以某一时点占主导的世代可婚男子数作为代用指标进行折算;户均口数使用家庭结构模型,以流域内多个聚落人口的婚姻、生育和死亡数据推算出时段上的平均值,再通过1953年流域人口的年龄构成和多个聚落的户均子女和老人数得到平均值作为经验值,代入1920年之前户均口数的重建中,得到长时序的户均口数。重建结果通过对比检验,表明该方法能较好地重建历史时期山地聚落代际分辨率的人口序列。分析发现,该山地聚落人口变化具有大起大落和阶段性发展的特征,且大落的速度比大起的速度快。     

广州榄园岭遗址先民祭祀遗迹的炭屑和植硅体分析

祭祀是先民生活的重要组成部分之一。尽管贵族祭祀活动的研究较多,但平民祭祀遗迹却由于发现较少而难以深入分析。广州榄园岭遗址春秋时期墓葬群中发现了越文化中常见的碎物祭祀坑。本研究对若干墓葬和相关祭祀坑中的填土开展了炭屑和植硅体分析。结果表明,先民在祭祀坑中有意燃烧过植物类祭品;用作祭品的植物种类较杂,包含扇型、棒型、方型或刺球型等植硅体。结合其他遗址中出现的类似现象,榄园岭先民的祭祀活动,应是在因地制宜、就地取材的基础上,吸收了苗蛮文化的因素,同时影响了其他地区。这一发现为探索先秦古人的祭祀行为提供了丰富信息;此外,炭屑和植硅体分析为确定祭祀遗迹提供了新的研究范式。     

Compositional Analysis of Ceramics from Goguryeo Fortified Sites in Central Korea

The aim of this paper is to investigate whether the ceramics from the Goguryeo fortified sites of the Han River region in central Korea were manufactured and consumed locally during the southern expansion of the Goguryeo State (475–551 ce ). For this research, 88 ceramic samples from seven contemporary sites in the southern territories of Goguryeo were sampled and analysed by ceramic thin‐section petrography and neutron activation analysis (NAA). In addition, to establish a possible chemical fingerprint at Hongryeonbong Fort 2, five clay specimens were also gathered and analysed from the pottery firing structure. The results of this analytical study indicate that the majority of the ceramics from the Goguryeo fortified sites of central Korea were produced and circulated within this newly acquired region. In addition, it is highly probable that Hongryeonbong Fort, which contains the remains of what may be ceramic firing architecture, is the place of production for the ceramics.     

Development of Collaborative Structure Analysis (CSA) System and Its Application to Investigate Effects of Soil-Structure Interaction

In this article, a collaborative structure analysis (CSA) system is developed for integrating different finite-element simulation programs. In this system, a simulated structure is divided into multiple substructures, and the interaction between the substructures is considered. Interfaces for the commercial finite-element program ABAQUS and for an open-source framework for structure analysis, OpenSees, are developed to achieve CSA integration. The CSA system is applied to analysis of a soil-structure interaction (SSI) problem, and the effects of SSI are investigated, and the efficiency and accuracy of the system are demonstrated.
