Sense of place and migration histories Idiotopy and idiotope

The aim of this article is to explore a methodological approach relevant to the study of population mobility. The approach considers not only the whole migratory process and the sequence of connected movements, but also what happens between each of them. The study of mobility is considered inseparable from the study of passage, permanence and settlement. This paper establishes the interest in elaborating concepts that express the interaction between people and places, and how these interactions contribute to an understanding of migratory processes and of 'place histories'. In this sense, geographical identification (idiotopy) and place identification (idiotope) are put forward as useful concepts.     

Structuring subjectivities? Using Q methodology in human geography

This paper presents a critical and reflexive account of using Q methodology in human geography. Q methodology has a long pedigree in psychological, political and sociological research, but is only recently beginning to be used by human geographers. We discuss, in particular, the parts of the process(es) of Q methodology that are often glossed over in the literature, through reflecting on our learning in using Q within a project examining the use and production of environmental science by NGOs. We conclude that Q may be a useful supplement to existing methods in human geography, as long as it is used creatively and reflexively and with full awareness of its interpretative dimensions.     

The Swedish Geotechnical Society’s methodology for risk management: a tool for engineers in their everyday work

The Swedish Geotechnical Society has adopted a general methodology for risk management in geotechnical engineering projects to reduce the costs related to negative outcomes of geotechnical risks. This technical note highlights the main features of the methodology and strives to inspire the international geotechnical community to apply sensible risk management methods. In the authors’ opinion, a successful geotechnical risk management needs to be structured, be tailored to the project, and permeate the engineers’ everyday work. Then, sufficient quality can be achieved in the project with larger probability.     

经济地理学制度理论的发展与建构的重要方向

在中国制度差异显著与目前区域发展不平衡不充分的现实下,经济地理学与制度相结合的研究显得尤为必要。通过系统地梳理经济地理学与制度的关系发现,经济地理学与制度在历史上存在先分离后融合的情况,并且目前经济地理学与制度研究结合态势不容乐观,制度研究在本体论、方法论、时间维度、空间尺度、研究方法等方面仍然存在不足。通过文献梳理与理论分析,认为经济地理学的制度理论应基于演化经济地理学进行建构,并提出了建构的方向:1)以系统论、层级观为指导,注重构建制度的层级结构;2)以反还原论为基础,寻求方法论的突破;3)借助演化的思想与路径依赖理论,强调时间在制度系统中的作用;4)加强对各空间尺度的制度研究;5)注重工具方法的借鉴与创新。     

Application and comparison of two symptom-based eutrophication-assessment methods in Jiaozhou Bay,China

Increasing numbers of approaches to assess eutrophication, such as estuarine trophic status, the Oslo-Paris Commission Common Procedure, and the Water Framework Directive, focus on the symptoms of eutrophication. In China, however, nutrient index methods dominate the assessment of coastal waters. In this study, an integrated method that includes both water quality and ecological response was compared with the Northwest Pacifi c Action Plan (NOWPAP) Common Procedure. Observation data from Jiaozhou Bay, Shandong, China, were used in a comparison of the two methods in a trophic status study. Overall, both clearly revealed a high level of nutrient enrichment in the bay, indicated by high nutrient concentrations. Though the two methods diff ered in their methodological design in the assessment of the ecological eff ects of nutrient enrichment, they have acquired similar results: the integrated method suggested that the status was good, and the NOWPAP Common Procedure suggested that the status was low (indicating that the bay had no serious eutrophication problem). The introduction of fi lter feeders (shellfi sh aquaculture) into the bay on a reasonable scale may have been eff ective in mitigating eutrophic conditions, and perhaps explains the low ecological impacts there. Our results will be useful to ecosystem-based eutrophication management in the bay and in similar areas.     

基于WSR框架的《开发区土地集约利用评价规程》指标体系分析

旨在剖析我国《开发区土地集约利用评价规程》中指标体系存在的问题并提出改进建议。在界定开发区土地集约利用内涵基础上,从要素特征(W维)、利用目标(R维)和评价过程(S维)等3个维度阐述了开发区土地集约利用评价的系统要求,构建关联分析矩阵,对《规程》中评价指标体系的特征差异化、层次完整性和目标关联性等3个方面进行了分析讨论。针对当前《规程》中存在的评价对象混杂、开发区类型需要细化、指标体系不完整、计算方法需修正等问题提出了相应修改建议。
