SPACE–TIME MEASURES OF DEMAND FOR SERVICE: BRIDGING LOCATION MODELLING AND ACCESSIBILITY STUDIES THROUGH A TIME‐GEOGRAPHIC FRAMEWORK

Demand for service in location modelling is often evaluated based on the spatial proximity of fixed and static reference locations of demand (e.g. home) to a facility, which ignores person‐specific activity–travel patterns and the temporal changes in demand for service throughout the day. To address these limitations, this study draws upon recent developments in space–time measures of individual accessibility to explore the spatial and temporal structures of demand by considering individuals' space–time constraints and impact of existing urban structures. Based on a time‐geographic framework, eight space–time demand measures were developed and compared with three conventional location‐based demand measures for 12 hospitals through an empirical study conducted in Columbus, Ohio. The results show that geographic proximity between clients' home and facilities may not be an effective indicator for service demand, and conventional demand measures tend to underestimate potential demand for service in most situations. The study concludes that space–time demand measures that take into account people's activity‐travel patterns in space–time would lead to better estimation of demand for service in most cases.     

梅调鼎生平事迹考释

一．生平及家史 现存最早的关于梅调鼎生平的史料,当推1930年出版的忻江明《四明清诗略续稿》卷四引慈溪冯歼《回风堂脞记》对梅调鼎的评论,而后人转引的材料却大多是1943年出版的《赧翁集锦》卷首慈溪叶伯允撰写的《赧翁小传》。     

透光摄影在古书画修复与研究中的应用

透光摄影由常规可见光摄影发展而来，是针对中国古书画等能被可见光穿透的文物开发的一项无损摄影检测技术。通过实践发现透光摄影在古书画的修复与研究领域具有多项作用：观察书画命纸、背纸拼接等装裱情况；发现前人加固、补缀等修复痕迹；获取画面底稿内容；强化伤况视觉效果以便于分析文物伤况病害。透光摄影能够提供直观可靠的深层视觉信息，辅助修复人员了解文物内部状态，在古书画的修复与研究中发挥重要作用。     

嵌入、认同、责任：地方社区中的旅游小企业

围绕旅游小企业根植于地方社区的社会理性本质,本文借助嵌入理论探讨旅游小企业经济活动背后社会责任行为的成因。研究发现：①旅游小企业主的地方认同对企业社会责任行为有着显著的正向影响;②旅游小企业主的社区嵌入对地方认同有着显著的正向影响;③旅游小企业主的地方认同在社区嵌入对企业社会责任影响中扮演着显著的中介作用;④旅游小企业主的地方身份特征在社区嵌入对地方认同的影响中起着显著的调节作用,社区嵌入中获得更多社会资源的外来小企业主比本地小企业主对地方认同的影响更强。本文揭示了旅游小企业社会责任的地方空间特征,形成了地理学人—地关系研究的新方向,并为社区嵌入管理和商业环境塑造等工作提供了实践启示和建议。     

汉代对羊纹金饰片初探

1968年,河北满城中山靖王刘胜墓出土5件金饰片(原文称金叶),上面捶揲对称的侧面羊首。无独有偶,1983年广州象岗山南越王赵眜墓也出土8件形制类似的金饰片(原文称金叶)。2004年,在江苏扬州西汉刘毋智墓的收缴文物中,再次见到了同样形制的金饰片。     

A framework for path-dependent industrial land transition analysis using vector data

Industrial land is under transition globally. Insights into this transition are important to plan a sustainable future. Since industrial land follows parcel shapes and the transition process requires multi-year data to observe the impacts of such changes, multi-year vector data should be used to analyse industrial land transition. This paper presents a framework to analyse path-dependent regional industrial land transition processes using vector data. A step by step instruction is presented. In the analysis, the changed percentages of land use in the surroundings of appeared or disappeared industrial land are visualized. The visualized surrounding land use compositions give planners an idea on what causes land use transitions, the most frequent transition forms and their impacts on the surroundings, purely from a land use point of view to reduce data collection efforts. The North Brabant region in the Netherlands is used as a case study. The region is split into urban and non-urban areas to show the generic applicability of this framework.     

Distance in Spatial Analysis: Measurement,Bias, and Alternatives

Distance is an important and basic concept in geography. Many theories, methods, and applications involve distance explicitly or implicitly. While measuring the distance between two locations is a straightforward task, many geographical processes involve areal units, where the distance measurement can be complicated. This research investigates distance measurement between a location (point) and an area (polygon). We find that traditional polygon-to-point distance measurements, which involve abstracting a polygon into a central or representative point, could be problematic and may lead to biased estimates in regression analysis. To solve this issue, we propose a new polygon-to-point distance metric along with two algorithms to compute the new distance metric. Simulation analysis shows the effectiveness of the new distance metric in providing unbiased estimates in linear regression.     

旅行的意义:大众旅游者自我发展的视角

旅游已成为个体寻求自我发展的一种手段。本文以大众旅游者个体为研究对象,探索旅游对旅游者自我发展的影响及其作用机制。研究运用扎根理论研究方法,对所搜集的资料逐级编码、概念化和范畴化,发现大众旅游者自我认知的变化具有普遍性,构建了旅游者情境自我发展过程的框架,最终得到核心范畴——旅游者自我发展。研究发现,旅游者在旅游过程中或结束后对自我的内省能够促进自我发展;影响旅游者内省行为的两条路径分别是情绪过程和意志过程;情绪过程受到旅游者对旅游情境因素的知觉和出游动机的双重影响;意志过程主要受旅游者出游动机的影响。     

Power,ideology and economy cultural policy in China

Abstract: Relying on the institutionalist framework, much literature conflating the structures of public action in the field of culture has been produced (e.g. papers concerning the targets of cultural administrations, levels of action, ways of financing cultural policies). In this context, cultural institutions have been considered as something given, but the question of their origins and shape has hardly ever been at stake. In other words, institutionalist theories make comparisons possible, but they deny any form of inner life to cultural administrations. It allows one to make static comparisons, but it fails to explain why national cultural administrations differ from each other. Hermeneutic philosophy mixed with historical institutionalism could then be used to refine traditional models. My point will be made with references to the French and American case-studies.     

关于佟养性研究中的几个问题

佟养性是清入关前的重要历史人物之一,学界研究清前吏的论著中多有涉及佟养性者,有些说法值得商榷.如佟养性的族属问题,即他究竟是满族人抑或汉族人;皇太极在组建汉军旗时,佟养性是否被任命为固山额真;佟养性的先祖佟达礼在明朝初年站在明廷一边,为其招抚女真人,而佟养性在明朝末年却站在后金一方,为反对明延而战,应当作何评价.笔者对这几个问题谈谈个人的看法.
