Caddoan Area archaeology since 1990

This paper summarizes recent archaeological research efforts, and changing perspectives, about the native history of the Caddo peoples who lived in the Caddoan Archaeological Area, which centers on the Great Bend of the Red River in Oklahoma, Texas, Arkansas, and Louisiana. Of particular focus are the origins and early developments of the Caddoan tradition, regional diversity, subsistence changes and agricultural intensification, sociopolitical dynamics, and Caddoan-European interaction.     

Spatial optimisation of fire service coverage: a case study of Brisbane,Australia

In the context of changing demand for fire services, spatial optimisation of fire coverage has attracted little scholarly attention despite its potential to improve emergency response and to inform future service planning for fire stations. Drawing on small area population forecasts, this paper extends the application of the Maximum Coverage Location Model to compute and delineate the spatial coverage of current and proposed new fire stations to align with population growth estimates for Brisbane, Australia. Our results reveal important gaps in fire cover that are likely to emerge as a result of predicted population growth, the spatial patterns of which varies across the Brisbane metropolitan area. We draw on these results to delineate a series of new potential sites for fire stations to ameliorate the reduction in spatial coverage as a consequence of predicted population growth demonstrating the utility of our analytic approach for decision‐making and operational planning in the fire services.     

闽台财政改革与各方权力纠葛--雍正朝台湾县知县周钟蠧案解析

雍正三年,台湾县知县周钟蠧被控贪污,由于牵涉到闽台财政改革的大背景,此案引起了雍正皇帝的高度关注,并演变为震动闽台官场的一桩大案,涉案人等都被卷入了皇权与地方官员博弈的大漩涡。案件的审理过程,伴随着闽台财政改革的全过程,从清查仓谷亏空,到耗羡归公和养廉银制度化的最终完成。透过考察周钟蠧案,闽台地区财政改革的过程得以完整呈现。在皇权的强势施压下,闽省官员提出的耗羡归公方案显得仓促而草率。     

L'identification des zones calmes et un diagnostic d’équité environnementale à Montréal

Quiet urban areas are places with low noise levels that can help people to support physical and mental wellness. This paper has two objectives: to identify quiet urban areas in Montreal and to check for the presence of environmental inequities in access to such areas for vulnerable groups (children, older people, low‐income individuals, and visible minorities). Using a GIS‐based methodology, 2,282 quiet urban areas were identified in Montreal. The results of a mixed effects logistic regression model analysis showed that there are no major inequities in access to quiet urban areas for the population groups studied. The analysis did, however, revealed substantial spatial disparities in terms of the distribution of quiet urban areas across the boroughs and municipalities examined.     

Does clean air increase the demand for the consumer city? Evidence from Beijing

Cities offer a large menu of possible employment and leisure opportunities. The gains from such consumer city leisure are likely to be lower on more polluted days. We study the association between daily consumption activity and outdoor air pollution in China and find evidence in favor of the hypothesis that clean air and leaving one's home for leisure trips are complements. Given the high levels of air pollution in cities in the developing world, regulation induced improvement in environmental quality is likely to further stimulate demand for the consumer city.     

六世纪中后期的中国联珠纹织物

联珠纹在中国虽有更早的源头,但它从6世纪中期才开始流行。那时中国的联珠纹虽以粟特地区为中介受到萨珊艺术的影响,但也融入了自身的文化理解和艺术形式,这令联珠纹在很大程度上丧失了原有的萨珊图案寓意、改变了西方原貌。邺城等黄河中下游的丝织重镇,应是联珠纹织物在内地的重要产地。     

襄樊邓城区域楚墓地考析

襄樊邓城区域是楚文化遗存分布的一个重要区域。1971年以来先后发掘了四处楚文化遗址和八处楚文化墓地,并出土了大量的楚文化遗物,其时代可分为春秋早、中、晚期和战国早、中、晚期。本文对该区楚墓地的分布、特点、性质、墓主人身份和与邓城遗址及周围遗址的关系等进行了初步研究。     

21世纪的"海洋破碎带"

本简析了海洋的争夺史,在此基础上提出了本的中心议题—21世纪的“海洋破碎带”。探析了“海洋破碎带”形成的七大因素,即：①海洋霸权主义对海洋国际贸易通道的争夺;②国际间对海洋国土的争夺;③海洋生物资源的争夺;④海洋矿产资源的争夺;⑤南极大陆的争夺;⑥海军军备竞赛;⑦海缘政治形势日益恶化。阐释了21纪“海洋破碎带”分布的海域。最后指出,中国不仅是一个陆地国家,也是一个海洋国家,中国的海上安全已近底线。为此,中国必须树立新的海洋观念,建立强大的海军,保卫国家的每一寸海洋国土。     

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.
