SHAKING TABLE DYNAMICS: RESULTS FROM A TEST-ANALYSIS COMPARISON STUDY

This paper presents the results of a comprehensive comparison study between the analytically predicted and experimentally identified dynamics of the shaking table system built recently in the Structural Engineering Laboratory at Rice University in Houston, Texas. The primary objectives of the research presented here are two-fold: (1) to shed light into the dynamic performance of asmall-tc-medium size, uni-axial, servo-hydraulic, displacement-controlled shaking table system, and (2) to validate a linearised dynamic model of the system (in the form of the total shaking table transfer function) developed earlier by the authors from basic principles. The analytical model incorporates the inherent dynamic characteristics of the various components of the shaking table system (i.e. controller, servovalve, actuator, test specimen, and reaction mass) and their dynamic interaction.

The test-analysis correlation study performed over a wide range of operating and payload conditions provides useful information on the sensitivity of the shaking table transfer function to control gain parameters and how it can be used to tune the shaking table controller for optimum performance under various payload conditions. The good test-analysis correlation results obtained validate the analytical shaking table model, show its robustness, and provide keen insight into the underlying coupled dynamics of a shaking table system. In order to achieve this good test-analysis correlation, it was crucial to include a time delay in the analytical model of the shaking table system (innovative feature of the model to account for the time lag in the response of the servovalve-actuator system). The expected significant dynamic interaction between payload and shaking table is also confirmed by this study.     

游客出游意愿影响因素研究——基于突发公共卫生事件的实证

本文在目标导向行为模型的基础上,构建了游客在面对突发公共卫生事件时各种影响因素对出游意愿影响的理论模型,为系统性的进行影响游客出游意愿的因素研究奠定了基础。在对经历过突发公共卫生事件后有出游经历的游客进行实证研究后,发现出游态度、感知行为控制和积极的预期情感对出游欲望有显著的正向影响;消极的预期情感对出游欲望有显著的负向影响;出游欲望对出游意愿有显著的正向影响。     

LOCAL PUBLIC SERVICES COSTS AND THE GEOGRAPHY OF DEVELOPMENT: EVIDENCE FROM FLORIDA COUNTIES

Theory suggests that the spatial distribution of development within a local jurisdiction affects the costs of providing local public services. We use GINI coefficients to characterize these distributions at the county level and estimate the effects on real per capita expenditures from reductions in the spatial concentration of all buildings and nine alternative types of development. We also estimate the effect on expenditures from expansions in the developed area of a county. The results obtained from a panel of Florida counties confirm our theory and suggest that the geography of development within a county affects public services costs.     

现代艺术运动发展演变的地理学研究

现代艺术是目前唯一在国际上占统治地位的艺术现象。本文从地理学角度出发研究现代艺术的发展演变。首先回顾了现代艺术的发展过程,重点分析了现代艺术的地域性特征,指出国际现代艺术体系有"中心-边缘"性的分布格局,从流派数量和艺术主题的变化方面总结了其发展演变特点,并且总结了历史上三次重要的艺术扩散过程。其次分析了我国现代艺术发展的时空分布和地理格局,指出我国现代艺术的中心位于东部沿海大城市,具有分布不均、在国际体系中地位不高的特征。最后指出我国城市积极参与国际现代艺术体系、提升文化艺术地位的重要性和途径。

EMPTY HOUSING SPACE: AN OVERLOOKED RESOURCE

The nature of the housing problem in the United States has changed over the years while the posed solutions have not. Today the U.S. has both a surplus of housing and a shortage–the housing space is not effectively distributed. This article suggests the magnitude of underutilization of our housing space and discusses the federal and local policies which encourage over-consumption and discourage voluntary redistribution. Some pertinent recent Supreme Court decisions are discussed.     

枢纽经济及其发展机制——以中国交通枢纽经济为例

枢纽经济是当前很多省份的重要区域发展战略,但是对枢纽经济内涵、发展机制等核心问题的讨论还不足以指导现实枢纽经济发展。文章构建并检验枢纽经济的发展机制,一方面界定枢纽经济内涵,从系统论的自组织和他组织视角使用区域循环累积因果模型推演出枢纽经济发展的四个阶段;另一方面以交通枢纽经济为例使用省级2007—2017面板数据检验主要变量的定量影响,并判断我国枢纽经济的当前所处阶段。主要结论:枢纽经济发展受经济系统自组织和政府他组织影响,是由初始变化形成阶段、次级强化形成阶段、产业竞合上升发展阶段、成熟阶段组成的循环累积因果过程;经验检验表明劳动力数量、公共基础设施配套、制度创新和技术水平显著影响枢纽经济;当前我国枢纽经济发展处于初始形成阶段,政府政策是触发关键;提高丝绸之路经济带沿线西部省份的枢纽数量和质量能有效拉动枢纽经济发展。     

古村落旅游开发的公共管理问题研究

与其它遗产地不同的是,古村落首先是生活着的村落,原住民及其生活是古村落的核心,这不仅导致古村落旅游目的地资源产权公私交错及其开发管理的复杂化,也使旅游开发利益主体及其利益诉求多元化。古村落的特殊属性决定了古村落旅游开发管理的特殊性和国家有关主管部门介入实施公共管理的必要性。本文从公共管理的视角,对古村落基本属性、古村落旅游地开发保护中公共管理问题的界定,以及实施公共管理的机制途径等问题进行分析。得出以下结论,古村落旅游地现状问题的核心是多方利益主体的利益诉求与社区核心利益之间的矛盾,政府为主导的公共管理对古村落旅游地开发管理具有不可替代的作用,制度约束与规范管理是现阶段古村落旅游地政府治理的重要途径。     

CALCULATING THE COST OF TRANSFERRING STUDENTS FROM PAROCHIAL TO PUBLIC SCHOOLS: AN EXAMINATION AND CRITIQUE

Public sector aid to K-12 parochial schools is often justified on the basis that providing assistance is cheaper than having to absorb all those students into public school systems. But is it? The cost of transferring students from parochial to public K-12 schools has never been satisfactorily calculated. This article points to the weaknesses in previous efforts and outlines the elements that must be present in a comprehensive estimate of transfer costs.     

转型中国的地方管治:海外学者的观点

改革开放以来,中国的城市与区域在分权化、全球化和市场化的宏观背景下,经历了剧烈的政治、经济和社会转型,地方管治成为城市地理学研究的热点问题。本文对海外研究中国地方管治的有关文献进行综述,总结了目前主流理论对中国地方管治变革的两种观点-强势的地方政府与低效的地方政府,并做出评述。研究同时也指出深化中国地方管治研究和地方政府间关系研究的新方向。     

城市发展研究的整体主义初探

科学发展观的提出以及复杂性科学的兴起,要求必须立足整体主义开展城市发展研究。在这种背景下,提出城市系统工程的命题,其本质是一种城市发展研究的整体主义方法论。城市系统工程的核心内容包括:时空观作为研究理念,城市与发展作为研究主题,城市系统、城市逻辑与城市制度作为研究维度,以及发展阶段、发展规律、发展战略和发展调控作为研究问题。针对城市系统工程的三种研究维度,给出了对应的研究方法体系。     

AN UPPER PALAEOLITHIC FLINT AND CHERT ASSEMBLAGE FROM HOWBURN FARM,SOUTH LANARKSHIRE,SCOTLAND: FIRST RESULTS

This paper describes the discovery of the first open‐air Upper Palaeolithic site to be found in Scotland, at Howburn, near Biggar in South Lanarkshire. An account is given of the composition and distribution of the lithic assemblage, which is discussed in terms of its British and north‐west European context. Provisional parallels drawn are with the Late Hamburgian (Havelte) sites and assemblages of southern Scandinavia, northern Germany and the Netherlands. There is no absolute dating evidence for the site, but an age in the region of 12,000 ¹⁴C yr BP, towards the end of the earlier (Bølling) Lateglacial Interstadial stage, is proposed on the basis of the lithic artefacts.     

从南京城市地理格局研究古都风貌规划

历史时期自然地理格局对于南京古都景观形成有至关重要作用。目前我国的古都风貌保护规划往往是从建筑学角度出发,而缺少对产生历史城市的自然环境变迁分析,以及相应的从地理研究角度的古都风貌保护规划。探查地理系统中的历史城市起源和发展的山水脉络,这对研究城市持续发展与特色继承有重要作用。现代南京城市发展支离破碎地分解了历史上的连绵山峦整体,河流水系网络已经断断续续。顺延山峦与河流脉络调查分析古都遗址是本文研究思路。本篇探讨以地理景观分析并规划形成南京古都风貌保护的地理格局网络:以连绵丘岗山系、河流城濠为骨干,保持山体轮廓的连续性,河流水网的完整性;以自然山水地形为纽带贯通各自相对独立的历史遗迹;以明朝城垣、历史街区为网络,以及分散在各地的重点建筑保护范围,构成完整的古都风貌保护的格局。     

历史文化保护区旅游开发的社区参与模式研究

近些年来,为了充分利用资源发展区域经济和满足社会的旅游需求,历史文化保护区(尤其是古城镇、古村落等)纷纷进行旅游开发,演化成旅游社区。社区居民以资产、人力资源、社区文化等不同的社区参与要素参与历史文化保护区的旅游开发,获得不同利益,形成三种不同的社区参与模式。论文在对三种参与模式进行分析的基础上,对当前历史文化保护区社区参与旅游开发存在的主要问题进行思考并探讨其解决的途径,提出应激励投入增大总效用、认定和提高社区居民的分利能力以及构建"社区参与"的利益保障机制等。
