区域形象测量内容的研究综述

本文将区域形象理解为区域客观状况的存在方式,并从实体形象、投射形象与感知形象三个层面对区域形象的测量内容进行综述。区域实体形象的测量内容大多围绕区域的客观属性展开,从区域规划设计角度强调区域现实资源的竞争力;区域投射形象测量通过对信息源及信息的内容分析,将样本内容中出现的高频特征词作为测量内容,以体现区域在媒体世界中的形象;区域感知形象测量则从目标受众的认知与情感两个方面进行,明确目标受众对区域现状、特征的主观看法与态度倾向。     

浅谈利用MAPGIS进行数字化地形图图斑拓扑及属性编辑

如何高效,准确地从数字化地形图中量取图斑面积及属性是测绘工程技术人员经常遇到的问题。本文主要叙述通过对数字化地形图中地形、地物等符号的线型转换,利用MAPGIS软件解决这个问题的工作流程。     

试论联合国大学与世界型学府的构建

全球化的加剧催生越来越多的知名高校走向国际化。以联合国大学为研究对象,在重点揭示联合国大学的决策、行政、学术管理机制的基础上,探讨了联合国大学属性,并较为全面地研究了联合国大学成立和运转的条件。从政治性上看,联合国大学属于国际组织;从经济性上看,联合国大学属于知识联盟;从学术性上看,联合国是一所大学或者研究机构;从社会性上看,联合国大学又是学术共同体。通过研究分析得出,一所真正的世界型大学必须具备5个特征:人力资源全球化;培养方式全球化;管理全球化;治学和教育理念全球化;决策权相对自主。期望所做的研究与分析为真正意义上的世界型学府构建提供理论支持和依据。     

BOT项目风险多属性群决策识别方法

本文提出的BOT项目风险识别方法可以客观计算专家的权重和风险属性的权重,反映不同专家、不同属性对决策结果的影响。通过把BOT项目风险决策矩阵转化成多维向量,用两向量的夹角余弦计算专家的相似度和差异度;利用熵值推导得到属性的权重,如果某个属性对决策所起的作用越大,则其熵值就越小、权重越大,并根据综合决策值排序得到风险识别结果。最后,本文通过一个典型的BOT项目验证了该识别方法的可行性和有效性。     

A comparison of citizen and “expert” preferences using an attribute-based approach to choice

This paper explores whether expert judgements can be taken as a proxy for citizen preferences for determining investment strategies for public goods. As an illustration, we focus on the provision of Public Rights Of Way (PROW) by Local Government Authorities in England. These provide rights of passage over property to those other than the owners, and little information is available on the welfare effects of changes in the provision and use of PROW. Given limited funds, reliance on expert judgement could be a cost effective alternative for decision-making compared with stated preference surveys of citizens. Two methods are compared. The Analytic Hierarchy Process (AHP) is used to elicit expert judgement to proxy citizen preferences for different attributes of PROW. The Choice Experiment (CE) technique is then used to derive preferences directly through personal interviews with citizens. Overall it was found that judicious use of AHP by experts can, in this instance, be used to represent citizen views. However, this result may not be easily generalisable to other settings.     

我国东西部地区技术相似度测度与差异分析

采用标准的技术相似度测量方法,定量测度了我国东西部各省份间的技术相似度,发现西部与东部省份之间存在技术结构差异,与北京和上海的差距尤其显著。分别以与北京、上海的技术相似度为基准,对东西部省份进行排序,证实了我国各省份之间的技术结构和地理分布、经济水平类似,东西部也是具有明显差异的。并通过分析东部省份之间、西部省份之间以及东西部省份之间的技术相似度水平,以找出西部各省潜在的技术转移来源地。     

上海市楼宇经济的发展形式及其对策研究

在知识经济革命背景下,正朝国际大都市迈进的上海应选取既具有知识密集型属性又具有都市型属性的产业来引领未来产业结构的调整与升级。具有高聚集度和高辐射力的楼宇经济不仅具有上述的双重属性,而且在上海的发展前景广阔。上海市楼宇经济中比较有发展空间的是总部楼、众师楼和知识传媒楼,针对其聚集度不高的问题,提出规划和布局应从整体入手、走产业集群道路、发展成高度聚集的"发展极"等对策。

Advancing formative measurement models

Formative measurement models were first introduced in the literature more than forty years ago and the discussion about their methodological contribution has been increasing since the 1990s. However, the use of formative indicators for construct measurement in empirical studies is still scarce. This paper seeks to encourage the thoughtful application of formative models by (a) highlighting the potential consequences of measurement model misspecification, and (b) providing a state-of-the art review of key issues in the formative measurement literature. For the former purpose, this paper summarizes findings of empirical studies investigating the effects of measurement misspecification. For the latter purpose, the article merges contributions in the psychology, management, and marketing literatures to examine a variety of issues concerning the conceptualization, estimation, and validation of formative measurement models. Finally, the article offers some suggestions for future research on formative measurement.     

Confirmatory tetrad analysis in PLS path modeling

The authors propose a CTA-PLS assessment routine for measurement models. This routine applies confirmatory tetrad analysis (CTA) in a manner which is consistent with partial least squares (PLS) path modeling assumptions. The conceptualization employs a bootstrapping procedure to accomplish an appropriate statistical test examining vanishing tetrads in CTA-PLS. The approach allows distinguishing a formative indicator specification from a reflective indicator specification. Applications using experimental and empirical data demonstrate the usefulness and effectiveness of CTA-PLS. As a means of evaluating PLS path modeling results, the routine assists researchers in avoiding potentially unrepresentative consequences of measurement model misspecification.
