Out of the Closet: The Importance of Stories and Storytelling in Planning Practice

This article argues that story has a special importance in planning that has neither been fully understood nor sufficiently valued. Planning is performed through story, in a myriad of ways. The aim here is to unpack the many ways we use story: in policy, in process, in pedagogy, in critique, as a foundation, and as a catalyst for change. A better understanding of the work that stories do can make us better planners in at least three ways: by expanding our practical tools, by sharpening our critical judgment and by widening the circle of democratic discourse.     

对我国地区经济发展中几个问题的思考和对策

地区经济如何发展直接影响着国民经济的大局。这是一个大课题,本文仅就其中的工业经济发展情况作初步剖析。此外,笔者在对大量资料进行分析的基础上,提出了一些对策,并以“影子价格”作为资源配置优化的原则。     

双波长激光共聚焦生物芯片检测与图像处理

基于共聚焦检测原理,建立了双波长生物芯片检测系统。采用体全息滤光片,利用其反射衍射和带阻滤光特性,无需切换或改变光路,在同一光路中即可实现Cy3与Cy5荧光双波长扫描检测。提出了基于顺序形态变换的生物芯片荧光点阵图像的网格化处理方法,并对Cy3与Cy5荧光试剂点样玻片进行了扫描实验,对实验所得荧光点阵图像进行了网格化处理。实验结果显示,系统的检测灵敏度达到0.1 fluo/μm2,网格化算法简单、有效。     

平面包络环面蜗杆啮合型面的数据矩阵

研究了平面包络环面蜗杆啮合齿面方程，并探讨建立基于网格矩阵的啮合型面的矩阵模型方法。采用网格划分表面点的矩阵表达模式，建立了基于数据矩阵的啮合型面模型，为实现平面包络环面蜗轮副啮合型面的进一步分析奠定了基础。

Path-breaking books in regional science

This article presents a collection of regional science books that longstanding members of the Regional Science Association International (RSAI) identified as path-breaking books. The most frequently nominated books include the classics by Isard, the seminal books in urban economics by Alonso, Muth and Mills, methods books by Miernyk, Wilson, Anselin, and Cliff and Ord, textbooks by Beckmann and Richardson, as well as the recent contribution by Fujita, Krugman and Venables. Reviews of these books, written by leading scholars from different continents, make up the major contribution of this article and are a testimony to the far-reaching influence of regional science in the academic literature.JEL Classification: A2, B2, B3, C00, R00With contributions by Michael Batty, Manas Chatterji, Kieran Donaghy, Bernard Fingleton, Arthur Getis, Michael J. Greenwood, Daniel P. McMillen, Gordon F. Mulligan, Jan Oosterhaven,Peter V. Schaeffer, Daniel Shefer. See the Appendix for contributors affiliations and contact information.     

数字区调新技术新方法—RS_OrthoMapper系统研制开发

为了适应当今数字区调工作的需要,开发一套3S技术有机结合简单实用的数字区调野外工作平台或软件系统,已成为燃眉之急。论文介绍了数字区调新技术新方法--RS_OrthoMapper系统研制与开发的基本需求、系统的总体结构与设计、系统实现等,并给出了系统中一些重要的逻辑视图。该系统在西藏昌务场和青海阿拉克湖等地区数字区调填图中示范应用,获得良好效果。     

基于网格划分策略的改进人工鱼群算法

人工鱼群算法是一种新型的随机搜索优化算法，初步研究表明该算法具有许多优良的性质。通过引入网格划分策略和禁忌搜索算法．对基本人工鱼群算法进行了改进，减少了迂回搜索的无用计算，同时也使人工鱼可以在解空间内进行更为全面的搜索，提高了搜索效率，加快了系统满意解域的确定；通过对变量空间进行网格划分，提供了获取系统最优解的方法，而且加强了对鱼群公告板信息的使用。实验表明，与基本人工鱼群算法相比，该方法具有明显的优越性。
