RELAXING ASSUMPTIONS OF PERFECT INFORMATION IN PARK VISITATION MODELS*

Variables related to urban park awareness are identified and methods for relaxing assumptions of perfect information in park use models are discussed. Park awareness is related to park characteristics (age and degree of development of the park), population characteristics (race, age, length of residence, recreation participation), and distance. Park attributes are stronger predictors of both park awareness and use than is distance. These findings parallel similar research on the cognitive aspects of shopping decisions.     

Towards models of strategic spatial choice behaviour: theory and application issues

Models of spatial choice behaviour have been around in geography urban planning for decades to assess the feasibility of planning actions or to predict external (competition) effects on existing destinations. Although these models differ in terms of complexity and key concepts, they all have in common that spatial choice behaviour is predicted as a function of the attributes of the choice alternatives and distance or travel time separation only. None of these models do take into account that the attributes of choice alternatives and travel time may be highly non-stationary and that often the utility that people derive from visiting a particular location also depends on the choice behaviour of other individuals. Under these circumstances, individuals may exhibit strategic choice behaviour. That is, they will choose particular choice options taking into account their expected behaviour of others such as to maximize their own utility. The purpose of the proposed paper is to discuss possible models of strategic choice behaviour for these urban planning problems. Theory will be outlined and some critical issues in the application of such models to problems of spatial choice will be discussed.

卫星云图、雷达回波在人工增雨时机选择中的应用

概述了干旱期间选择飞机和高炮人工增雨作业时机的方法，以2000年6～7月哈尔滨地区特大干旱期间进行的飞机和高炮人工增雨作业为例，利用卫星云图和雷达回波资料选择的作业时间和作业区域应是比较有利的。因为从卫星云图中的水汽图、红外和可见光云图上可分析出云系中的含水量、云顶温度、云系强度，在此基础上利用天气雷达跟踪订正，可直接指挥飞机和高炮在有利的区域和时间内进行作业，获得了明显的效果。     

The evolution of the electronics industry in Johor (Malaysia): Strategic coupling,adaptiveness, adaptation,and the role of agency

Bringing together concepts from the global production networks and evolutionary economic geography literature, this article empirically examines the trajectory of the electrical and electronics industry in Johor (Malaysia). Based on trends in firm entries and exit as well as interviews with companies, we find limited robustness in the industry’s trajectory. While there is evidence of the role of ‘structure’ in this outcome, we argue that human agency – particularly the actions of subnational policy-makers – is key. This is manifest in a preference for fostering regional ‘adaptiveness’ through the often uncritical promotion of a diversity of economic sectors. This compromises the meaningful pursuit of regional ‘adaptation’ in the form of new and more complex branches emerging from existing industries. This arrested development, in turn, hinders an effective strategic coupling between the regional economy and multinational corporations, thus undermining regional resilience.     

区域综合地质调查助力乡村振兴的关键内容、战略路径与未来对策

区域综合地质调查是助力乡村振兴的基础性工作和重要技术支撑。本研究基于地质视角解读乡村振兴,围绕乡村人地安全、产业发展、地质文化、环境保护等方面进行剖析,提出地质灾害调查、工程地质评价、水文地质调查、农业地质调查、旅游地质遗迹调查等区域综合地质调查助力乡村振兴的关键内容;为提高助力效率效果,需做好项目顶层设计、制定乡村地区区域地质调查技术要求等标准、构建服务地方工作机制、开展系统人才培训培养等战略路径。未来乡村发展中,应进一步解决区域统筹部署与重点发展村镇选择、综合地质调查与乡村规划建设空间尺度匹配、综合地质调查和纵向专业性调查配合使用、工程地质评价与乡村地下空间集约利用、地质文化村建设与乡村规划建设衔接等问题,不断提高区域综合地质调查技术方法的服务能力,为乡村可持续振兴提供解决思路和方案。     

Household dependence on solid cooking fuels in Peru: An analysis of environmental and socioeconomic conditions

Solid fuel use is linked with adverse effects on the environment and human health. Yet, solid fuels remain an important energy source for households in developing countries. Even when country-level dependence on solid fuels is modest, there is often significant variation in within-country patterns of solid fuel use. This study examines a range of environmental and socioeconomic conditions to understand the relationship between them and household energy use within a country. While our results are derived from a study of regional patterns of solid fuel dependence in Peru, the contribution of this study is broad: variables that we include in our models of households’ fuel choice decisions are likely to shape such decisions in most developing countries. Our findings indicate that environmental conditions, such as elevation and forest cover, are associated with solid fuel use. Socioeconomic factors, including urbanization, poverty and female literacy, are similarly important. In addition, we identify nuanced links between types of female employment and indigenous population, on the one hand, and solid fuel use, on the other.     

Managing by principle: A critical analysis of the European principles of Integrated Coastal Zone Management (ICZM)

A set of eight principles is contained in the European Recommendation on Integrated Coastal Zone Management. The principles have been adopted with the minimum of critical review. The six core principles form two groups, one concerned with strategic goals and one that has a local focus. The principles are presented as a menu of free-standing options, with no prioritization either within or between groups. This can produce irreconcilable differences in strategy. The principles require clarification, prioritization of the strategic principles and recognition that they are an indivisible integrated set which should not be used to select principles to advance a particular agenda.
