长江三角洲大都市区划分研究——兼论中美大都市区界定指标体系的比较

本文运用中国大都市区界定指标体系,根据2002年数据对长江三角洲大都市区进行了重新划分。从划分的结果看,后者与前者相比发生较大变化。而中国大都市区界定指标体系对这种变化表现出了一定的不适应性,因此本文试图通过中美大都市区界定指标体系的比较研究为中国大都市区界定指标体系的修订提供参考。     

北宋御辽战略的演变与"澶渊之盟"的产生及影响

北宋初确定了通过北伐收复燕云地区,以扭转被动局面的御辽战略思想。宋太宗在两次北伐失败后,放弃以往的主动战略,转而实施全面防御的部署。宋真宗朝继承了“守内虚外”的思想,因此最终与辽达成“澶渊之盟”。“澶渊之盟”的订立,固然维持了长期的北部和平局面,但却给宋朝的国防战略带来了极大的消极影响,使宋廷过分依赖议和的手段,轻视了武备建设,从而令边防陷入长期被动挨打的境地。

1924-1945年国民党海外部与侨务工作考论

针对目前学术界在民国侨务政策、侨务工作方面的研究对象主要是侨委会,对于海外部仅粗略涉及的现状,依据相关档案及其它文献资料,对国民党海外部的沿革、职能、其侨务工作实绩及与侨务委员会之间的关系等方面做了分析和阐述。认为国民政府的侨务委员会与国民党海外党部从党政两个权力系统推展侨务工作,二者分工合作,相辅相成。抗战前,以侨委会为主;抗战爆发后,特别是太平洋战事发生以及日本推行南进政策后,以海外党部为代表的党务系统在侨务工作中发挥了更大的作用。     

一种古籍修复用纸伸缩性检测方法的探讨

补纸选配是古籍修复中的重要环节,但其伸缩性尚未引起足够重视。古籍修复补纸均为传统手工抄制,浸水后强度较低。按现行国家标准浸湿法检测补纸伸缩性时易产生撕裂、变形等问题,适用性较差。本研究探讨了一种古籍修复补纸的伸缩性检测方法——喷润法。利用水分检测仪对补纸相对含水量进行测定,从测量时间和可操作性的角度验证了该方法的可行性。通过十余种常用补纸的伸缩性检测结果发现,喷润法与浸湿法所得结果具有较好的一致性。随后探讨了古籍书叶伸缩性检测的适用性,并结合具体案例,建议在修复前分析古籍书叶与补纸的伸缩性匹配度。喷润法有效避免了补纸浸湿后的拉伸变形或破裂,既适用于古籍修复补纸,也适用于古籍书叶的无损检测,可为古籍修复策略的制定提供科学依据和参考。

In this article, I discuss the role of the three Scandinavian central banks in the establishment of the Bank for International Settlements (BIS) in 1930, and in the international lender of last resort operation towards Austria in 1931. I argue that small central banks were reluctant supporters in the establishment of the BIS and free riders in the Austrian crisis, even though there were marked differences in their attitude to international cooperation. These results run counter to the views of those International Political Economy (IPE) theorists who argue that small states should be in favour of international cooperation. On the other hand, the evidence seems to confirm Kindleberger's hypothesis that small countries were free riding during the international financial crisis of 1931, and that therefore there is a need for some coordinating mechanism, or a hegemon, in such crises.     

Solutions and frictions in civic hacking: collaboratively designing and building wait time predictions for an immigration office

Smart and data-driven technologies seek to create urban environments and systems that can operate efficiently and effortlessly. Yet, the design and implementation of such technical solutions are full of frictions, producing unanticipated consequences and generating turbulence that foreclose the creation of friction-free city solutions. In this paper, we examine the development of solutions for wait time predictions in the context of civic hacking to argue that a focus on frictions is important for establishing a critical understanding of innovation for urban everyday life. The empirical study adopted an ethnographically informed mobile methods approach to follow how frictions emerge and linger in the design and production of queue predictions developed through the civic hacking initiative, Code for Ireland. In so doing, the paper charts how solutions have to be worked up and strategies re-negotiated when a shared motivation meets different data sources, technical expertise, frames of understanding, urban imaginaries and organisational practices; and how solutions are contingently stabilised in technological, motivational, spatiotemporal and organisational specificities rather than unfolding in a smooth, linear, progressive trajectory.     

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.     

Poland in the ‘Paris system’: self‐determination,stereotypes, and decisions in 1919

One of the most important questions at the 1919 Paris Peace Conference was what to do about the newly re‐created state of Poland. The Paris peacemakers realised the importance of the settlement, thanks in part to dire warnings about Poland's future, and the leaders spent much time discussing the territorial settlement. Yet discussions of this important question regularly strayed from debates about policy to incorporate understandings of Polish national character. In particular, the leaders of the so‐called Big Three, Britain, France, and the United States, connected expert opinion and the broader political landscape to stereotyped understandings of national character, among other factors. With reference to scholarship on stereotyping, this article analyses how developing attitudes on Polish national character became integrated into the complex settlement of Poland's borders. The peacemakers' decisions, which were a compromise between different points of view, reflected interconnected understandings of the Polish settlement.
