Being genealogical in digital geographies

In this intervention, I trace the genealogies of the recent heralding of digital geographies as a boundary object for scholarship and scholars foregrounding the digital in geography. Building off of previous efforts to be technopositional in digital geographies, I make an entreaty for further being genealogical by attuning to the insider/outsider positionalities that have informed this particular endeavour of intellectual community‐making in Anglo‐American geography. While genealogy is not an exercise in historical narration, it works against dehistorical narratives of digital technologies and of the disciplinary frameworks within which they are engaged, destabilizes technopositional privileges, and has the potential to engender more inclusive digital geography futures.     

清代东北八旗界官研究

清代东北地区基层社会的官制,长期具有"旗民分治"的特点。在各处八旗驻防地,尽管八旗制度长期存在,但在八旗制度内部,为应对旗人越旗居住、耕种,以及同一村屯内旗民杂处等若干新问题,各地方旗署将驻防地的村屯按照地域划分成若干界,拣选在旗当差的佐领、防御及世职云骑尉等,委为一界之界官,专办管界内的各项差务。清代东北各八旗驻防地的界官名称不同,设置时间不一,所司职责呈现一定的时空差异,但其旗界内基层承管官的角色不曾改变。界官所承办差务繁杂,主要是维护管界内的社会治安,承办界内旗民人等的涉农事务,督倡本界旗民的风俗教化等。东北地区的八旗界官,在咸丰至同治年间发展到鼎盛时期,自同治朝以降的同光宣三朝,因民治地方官的增设,练、防军及乡团练勇的募练,尤其是光绪末年至宣统年间四乡巡警的创办,八旗界官的职权被分割,因而迅速走向衰亡,但其作为清代东北八旗驻防地区基层行政官制演进中重要一环的地位无可替代。     

Zionist identity and the British Mandate: Palestine's internment camps and the making of the Western native

This paper examines the relationship between British police officers, Jewish guards, and German internees in Palestine's internment camps during World War II. Using the reports of the Jewish guards, the paper investigates the role of Western‐identified actors in the Zionist identity‐making project. The reports evince a surprising rapport between the British and their German prisoners and the mistreatment of the Jewish guards by their British superiors. The paper analyses these Jewish accounts in the context of identity‐ and ethnic boundary‐making and argues that they illustrate Zionism's intent to construct itself as a Western but noncolonial movement and Zionists in Palestine as natives but not “Orientals.” The reports also reveal a breach between the formal hierarchy—British officers, Jewish guards, German internees—and the ethnic order, which situated British and Germans at the apex and the Jews at the bottom. The paper highlights the utility of researching group‐making interactions in different contexts to develop a more nuanced understanding of identity‐making processes.     

邓承修与中法桂越段边界交涉——以台北“故宫博物院”典藏桂越段边界条约档案为中心

清中期以前,越南被视为藩属,清廷未曾与其划分明确界线。中法战争后清廷与法国签订《中法会订越南条约十款》,越南与清朝藩属关系断绝,划界之议遂启。光绪十一年,清廷派邓承修与法国官员进行划界事宜谈判,经过冗长的交涉辩论,最终双方签订界约、绘制界线舆图。台北“故宫博物院”藏邓承修与法国勘界官员所订条约、界图和相关档案,是还原这段桂越段边界交涉情形的重要资料。     

固定和浮放条件下文物展柜动力响应分析与试验研究

目前对文物保护的研究主要以试验为主,本研究试图用数值方法分析文物展柜的动力学特性,以解决试验分析方法所导致的缺陷。为此,对固定和浮放两种不同边界条件的文物展柜进行地震作用和简谐激励下的动力响应分析,给出了展柜展台面处的加速度动力放大系数(简称放大系数)上限值。以某博物馆展柜为原型,按1∶1/0.39进行缩尺振动试验,得出两种边界条件下展柜展台面处的放大系数。对试验展柜建立有限元模型,通过与试验对比,验证模型及分析方法的正确性。然后,建立展柜模型的有限元模型,对5种尺寸的展柜进行了动力响应分析,并考虑激励幅值、激励频率等对放大系数的影响。分析结果有助于指导文物的防震保护工作。     

Illustrating the Phaenomena: Celestial Cartography in Antiquity and the Middle Ages

Abstract

The Ordnance Survey's Boundary Survey, carried out between 1841 and 1888, was a major undertaking which resulted in the local administrative boundaries of the whole of Great Britain being reliably mapped for the first time. This was not achieved by imposition but by the use of local knowledge of boundaries, thus making permanent a communal memory of administrative geography and rendering it globally accessible through maps. The Boundary Survey aided the reform of local government areas, a process which started during the same period and provided derived data for the burgeoning collection of statistics in the nineteenth century.     

Boundary spanning in social and cultural geography

This article situates interactions between German- and English-language social and cultural geographies since the mid-twentieth century within their wider intellectual, political and socio-economic contexts. Based on case study examples, we outline main challenges of international knowledge transfer due to nationally and linguistically structured publication cultures, differing academic paradigms and varying promotion criteria. We argue that such transfer requires formal and informal platforms for academic debate, the commitment of boundary spanners and supportive peer groups. In German-language social and cultural geography, these three aspects induced a shift from a prevalent applied research tradition in the context of the modern welfare state towards a deeper engagement with Anglophone debates about critical and post-structuralist approaches that have helped to critique the rise of neoliberal governance since the 1990s. Anglophone and especially British social and cultural geography, firmly grounded in critical and post-structuralist thought since the 1980s, are increasingly pressurized through the neoliberal corporatization of the university to develop more applied features such as research impact and students’ employability.     

行政边界区域土地利用与空间发展模式研究——以长株潭结合部为例

以长株潭结合部暮云镇为例,主要采用2004与2010年土地利用数据,从动态变化与多维综合视角,对行政边界区域土地利用与空间发展的特征、机制及问题进行系统分析,在此基础上归纳理论模式。研究表明:①暮云镇土地利用结构由农村型向城镇型快速转变,城镇用地比重年均约增加2个百分点,其中居住、教育科研、交通和工业等用地增加显著;②受主体功能定位、过境通道建设、周边城市辐射差异和规划管理制度变迁等因素影响,暮云镇空间格局与扩张模式快速演变,芙蓉大道沿线新增城镇用地占全镇82.78%,北、中、南区域开发强度分别上升20.95%、7.96%和1.58%,城镇用地平均图斑面积增长2.04倍。③研究区土地利用与空间发展存在诸多阶段性和结构性问题,应加强综合路网建设、公共设施用地供给、建设用地优化布局与集约利用以及生态环境保护。     

Chemical modification of pyroclastic rock by hot water: an experimental investigation of mass transport at the fluid–solid interface

Hydrothermal water–(pyroclastic) rock interactions were examined using flow-through experiments to deduce the effect of mass transport phenomena on the reaction process. A series of experiments were conducted over the temperature range 75–250°C, with a constant temperature for each experiment, and at saturated vapour pressure, to estimate the apparent rate constants as a function of temperature.
Based on the chemistry of analysed solutions, the water–rock interaction in the experiments was controlled by diffusion from the reaction surface and by the existence of a surface layer at the rock–fluid interface, which regulated the chemical reaction rate. The reaction progress depended to a high degree on flow velocity and temperature conditions, with element abundances in the fluid significantly affected by these factors. Mass transport coefficients for diffusion from the rock surface to the bulk solution have been estimated. Ca is selectively depleted under lower temperature conditions ( T  < 150°C), whereas Na is greatly depleted under higher temperature conditions ( T  > 150°C), and K reaction rates are increased when flow velocity increases. Using these conditions, specific alkali and alkali earth cations were selectively leached from mineral surfaces. The 'surface layer' comprised a 0.5–1.8 mm boundary film on the solution side (the thickness of this layer has no dependence on chemical character) and a reaction layer. The reaction layer was composed of a Si, Al-rich cation-leached layer, whose thickness was dependent on temperature, flow velocity and reaction length. The reaction layer varied in thickness from about 10⁻⁴ to 10⁻⁷ mm under high temperature/low fluid velocity and low temperature/high fluid velocity conditions, respectively.
