基于内隐联结测验的旅游目的地形象偏好测量研究

传统的旅游目的地形象测量只关注旅游者外显层面的认知过程,即测量旅游者外显评价,而忽略了对旅游者内隐认知的测量。本研究将内隐联结测验引入旅游目的地形象研究领域,同时结合自陈式问卷以香港和韩国为例探讨旅游目的地形象外显测量结果与内隐测量结果是否存在差异。研究结果表明,被试对香港和韩国的外显旅游目的地形象的认知不存在显著差异,而对两地内隐旅游目的地形象的认知存在显著差异。本研究有助于推进旅游者行为的内隐认知研究,同时丰富旅游目的地形象的测量方法并对旅游目的地营销具有重要的实践意义。     

北京市公共服务设施供需协调发展的时空演化特征——以教育医疗设施为例

公共服务设施的优化配置是构建和谐社会、改善民生的内在要求。本文通过构建协调发展度模型,对北京市2001年和2012年16个区县教育医疗设施供需关系及二者协调发展的时空演化特征进行研究。研究认为:①教育设施"供不应需",供需差距增大;协调发展等级总体较低且有下降趋势;协调发展水平由"东高西低"向"南高北低"格局演变,空间差异增大。②医疗设施"供不应需",供需差距缩小;供需协调发展等级较低但有上升趋势,空间格局由"中心集聚"向"南高北低"演变,空间差异减小。     

陕西省农村土地流转迟缓的供求影响因素与机制探析

农村土地流转长期受到决策者的鼓励,但我国农村土地使用权流转率一直偏低,西部地区尤其如此。本文试图以陕西省为例,通过问卷调查和访谈,分析农地社会保障功能等因素影响农地使用权流转率的作用机制;并从供给和需求两个方面,分析了经济落后地区农村土地使用权流转率偏低的原因。研究结果表明,农地流转受到现行的以提供社会保障为基本目的的农地制度的约束,任何旨在提高农地流转率的改革措施,都必须考虑现行农地制度的社会保障功能和地区差异,实行因地制宜的农地流转制度。     

What Determines Homeland Security Spending? An Econometric Analysis of the Homeland Security Grant Program

The distribution of State Homeland Security Grants has been characterized as pork barrel spending, where political considerations and not terrorism risk are determining the allocation each state receives. Using revealed preference analysis, we test this claim. From 2004 to 2006, measures of terrorism risk are found to be positive determinants of funding while measures of political influence and party affiliation of elected officials show no positive relationship with grant funding. These results are not compatible with the assertion that funding is distributed due to political factors.     

从楚墓出土丝织品的色彩看楚人“尚红”

楚人有“尚红”之俗,以红色为贵。本文以楚墓出土的丝织品为主要考察对象对楚人的“尚红”习俗进行了进一步探讨,认为红色在楚人的色彩观念中占据重要地位,以红色为贵,明确带有政治和社会功能,表现了鲜明的等级观念,可以说,红色是楚人上层社会的标志之一。我们不能把”尚红”简单地理解为楚地流行红色或以红色为主。     

人工神经网络：一种新的旅游市场需求预测系统

本探究了人工神经网络(ANN)作为一种新型的预测系统在旅游市场需求研究中的重要性,并指出：在对旅游需求进行预测时,人工神经网络较之多元回归分析方法适用范围更广,显性更强。     

中国旅游业地域不平衡分析

由于多种因素:中国自然地理条件、社会历史文化、经济状况等的区域差异,使我国旅游业表现出地域差异。因此本文根据三大地区的划分,着重比较了各地区的供给与需求的差异,并分析了其差异性的根源。在旅游供给的地域不平衡部分,对旅游供给的四个部分:旅游资源及其开发阶段与趋势、旅游设施、旅游服务、旅游基础设施进行分析。在需求的地域不平衡部分,对国内旅游、海外旅游、出境旅游逐个进行了分析。最后提出了我国区域旅游业发展的策略。     

大都市区居民对新兴边缘城市的认知与迁居意向——以天津大都市区为例

目前天津经济技术开发区(TEDA)已发展成为天津大都市区的新兴边缘城市。本文以居民问卷调查的第一手资料为基础,分析天津大都市区内各地区居民对TEDA的认知程度与迁居意向以及地域选择性特征,为以TEDA为核心的人口反磁力中心建设为主导的天津大都市区人口调整对策提供科学依据。     

ESTIMATION OF NEAR-SOURCE GROUND MOTION AND SEISMIC BEHAVIOUR OF RC FRAMED STRUCTURES DAMAGED BY THE 1999 ATHENS EARTHQUAKE

On September 7, 1999 an earthquake with magnitude M _W =5.9 occurred close to the city of Athens in Greece. More than 80 buildings collapsed, about 150 deaths and hundreds of injuries were reported. Soon after the event a damage investigation was carried out by two of the authors in the most heavily struck areas. The most serious damages were observed in the northern suburbs of Athens, where reinforced concrete frames and masonry buildings represent the prevalent construction systems. The hysteretic energy demands imposed on RC buildings should have been rather severe considering the structural systems characteristics and the inadequate construction details. However, over-strengths, redundancy and especially the presence of infill walls, provided a significant increase of the seismic capacity and contributed to the survival of many buildings.

The objective of the present work is to reproduce and analyse the response of typical RC frames subjected to the 1999 Athens earthquake in areas where the observed damage was particularly severe but no recordings of the ground motion were available. After a general overview of the seismotectonic environment, seismological data, observed macro-seismic intensities, structural typologies and observed building behaviour, an attempt is made to identify representative excitations in the meizoseismal area. Specifically, the required accelerograms are obtained by modifying available records so as to reproduce a given global energy content and to be consistent with the observed damage. To study the seismic response of RC models, the obtained accelerograms are used to perform nonlinear dynamic analyses.     

EVALUATION OF DEFORMATION CAPACITY FOR RC T-SHAPED CANTILEVER WALLS

If RC structural walls are properly designed and proportioned, these walls can behave in a ductile manner. To achieve this goal, the designer should provide adequate strength and deformation capacity of structural walls corresponding to each performance level (e.g. immediate occupancy, life safety and collapse prevention). This study investigates the drift and ductility capacities of T-shaped structural walls on the basis of results from experimental tests and sectional analyses. To determine proper deformation capacities for T-shaped structural walls, structural performances of T-shaped walls were evaluated with several parameters such as longitudinal reinforcement ratio, distribution of longi-tudinal reinforcement, lateral confinement ratio, and axial load ratio. Based on these results, the level of deformation capacity specified in current design provisions (ICBO, UBC 1997), which were expressed as both strain-based damage limit and interstorey drift ratio, were evaluated.
