Geographical knowledge and policy: the positive contribution of discourse studies

The 'discursive turn' has been blamed for a lack of engagement between geographers and policymakers. This paper argues that such a view is fundamentally flawed. It ignores the positive contribution that discourse analysis has made to policy studies and the particular role that geographers have played in developing such analyses. It is based on a misconceived view of the policy process and how knowledge can contribute to policy outcomes. A closer attention to policy discourses reveals exactly how knowledge is constructed within the policy process and can help identify how policy may be improved through discursive means.     

Research relevance, 'knowledge transfer' and the geographies of CASE studentship collaboration

The Co-operative Awards in Science and Engineering (CASE) studentship programme of the UK Research Councils provide one example of wider efforts internationally to encourage so-called 'knowledge transfer' and thereby harness publicly supported university research more closely to the goals of national competitiveness, regional economic development and local regeneration. In this paper we describe the implications of how the various UK research councils have interpreted the objectives and beneficiaries of 'knowledge transfer', both for the relative opportunities available to human and physical geographers for collaboration through CASE and for the sorts of values that their research must serve. Then, we draw on unpublished data from the Economic and Social Research Council (ESRC) to explore the geographies of CASE studentship allocation and participation. The broad regional and institutional patterns of participation we describe have important implications for ongoing debates in the UK about research selectivity and the role of the university as an engine of local development, while the striking disciplinary patterns of CASE participation, and in particular the overwhelming success of geographers in this competitive programme, provide an opportunity to reassess claims about whether and for whom geographical research is relevant.

Looking for the critical geographer, or why bodies and geographies matter to the emergence of critical geographies of Latin America

This paper argues that critical geographies of Latin America begin with an analysis of how and why the bodies and geographies of geographers themselves matter. To focus on the geographer as a producer of knowledge is not to advocate the kind of navel gazing so abhorrent to many scholars. Rather, it is an effort to call attention to and critically assess how the geographer's embodied social position and geographic location inform the production of knowledge about and representations of Latin American people and nature. To illustrate how and why bodies and geographies matter, I draw from feminist and post-colonial theory and include examples from my own experiences and those of other researchers doing fieldwork in Latin American countries. I conclude by exploring the notion of situated knowledge as a tactic that writes bodies and geographies into academic texts. Ultimately, situating knowledge represents a political intervention and contribution to the broader goals of emancipatory politics shared by critical human geographers.     

基于规则的OpenStreetMap数据模型转换

周边区域地理信息的获取是我国地缘环境研究中的一个难题,志愿者地理信息(volunteered geographic information,VGI)的兴起为解决该难题提供了一个可行的方法。在目前一系列的VGI项目中,OpenStreetMap(OSM)是比较领先的应用,但OSM数据模型不同于我国周边应用的专业矢量数据模型,因此,利用OSM数据时首先需要对其进行模型转换。有鉴于此,本文提出了一种基于规则的OSM数据到专业应用矢量数据模型转换方法。该方法首先利用OSM定义的几何类型与地物属性作为分类依据,建立了模型转换基本规则库;对于志愿者根据自己的理解自行标注未包含在基本规则库中的目标采用人机交互方式进行模型转换,并在此过程中不断完善规则库,利用越南与巴基斯坦数据进行实验,最终形成了包括2 344条转换规则的模型转换规则库,为OSM数据模型到专业应用矢量数据模型的转换提供了一条可行途径。     

重要性权值的驾车导航POI表达规则

在导航电子地图中,针对驾车任务的POI自适应表达是提高导航电子地图信息传输效率的关键。针对这一问题,提出了基于重要性权值的驾车导航POI表达规则。首先,分析了POI重要性权值的影响因素;其次,从影响因素出发,研究了基于权值的POI规则表达的各规则项;最后,设计了POI自适应表达规则库,并在嵌入了数据处理规则库的绘图软件上进行了技术实现。试验结果表明,利用基于权值的POI表达规则进行地图表达,可以提高地图内容的层次性与清晰性,优化驾车导航服务。     

论虚拟地理环境对地理知识的表达与共享

地理知识是通过对地理科学领域独特的背景、过程和结果进行解释而得到的知识。如何有效表达和共享地理知识是地理学研究和应用中的重要问题。本文首先将地理知识划分为3个层次,事实型知识、规则及控制型知识和决策型知识,分析了不同阶段地理语言对地理知识表达与共享的支持能力。对比地图和GIS语言,发现新一代地理语言—虚拟地理环境VGEs(Virtual Geographic Environments)能够较为全面地支持3个层次的地理知识。针对VGEs,从多个角度分析了其服务于地理知识表达与共享的能力,包括虚实结合理论、地理模型库及管理系统、动态可视化表达和异地协同工作环境。结合面向珠江三角洲地区空气质量研究问题的虚拟地理环境平台,对上述各方面进行了阐述。最后从地理知识生成、管理与应用角度对未来研究提出展望。     

《地图学》多元教学方法改革与实践

针对测绘工程专业传统的《地图学》课程教学中存在的只注重理论教学、教材内容陈旧、缺乏贴近学生实际和当前测绘科技发展的问题,该文提出《地图学》的多元教学方法,即将教书育人理念融入课堂教学、现代教学手段融入传统课堂及书本理论教学融入实践体验的教学方法。     

“To Understand the Place”: Geographical Knowledge and Diplomatic Practice

Diplomats produce a great deal of geographical knowledge: By reporting on distant places to their governments, they create particular understandings of political space. Yet these professionals rarely link their work to geography: What a geographer might call a geographical sensibility is labeled cultural knowledge by a diplomat. This article clarifies the relationship between geographical knowledge and diplomatic practice. Empirically, it draws from nearly 100 interviews with foreign policy professionals to offer a more “peopled” or quasi-ethnographic account of diplomacy than is usually available in scholarly literature. Conceptually, the article contributes to our understanding of how geographical knowledge is created inside diplomatic and bureaucratic institutions.     

胶东金翅岭金矿构造控矿规律及找矿预测

金翅岭金矿是胶东招远北部的一个典型石英脉型金矿,构造是金矿最为重要的控矿因素。在前人资料的基础上,综合分析了矿区构造控矿特征,总结了构造控矿规律:矿脉分支复合,表现为NE向矿脉产生SN,NNE向次级矿脉,NNE向矿脉产生NE向次级矿脉;矿体厚度与金品位呈负相关,深部次级矿脉群在P4脉下盘出现;矿脉侧伏角和倾伏向变化处矿体富集,表现为SW向侧伏的P4矿脉,矿体富集于-240 m,侧伏角变大,同时倾伏向由SW向转变为NW向的部位。最后建立了平面和剖面P4矿脉的波形函数,并对深部进行了预测。
