研究会展社会影响尺度与独立变量的相关性是会展社会影响研究的重要组成部分,对于扩大积极的会展社会影响和控制消极影响有着重要的实践意义。研究了11个独立变量与会展社会影响尺度的3个公共因子之间的相关关系,结果表明,独立变量对公共因子的影响有限,只有性别、居住地、居住时间、文化程度、收入和在相关行业工作等6个独立变量与会展社会影响感知显著相关。广交会案例表明:第一,性别方面,女性的个人收益感知强于男性。第二,居住地方面,海珠区居民对广交会社会影响的正面感知最弱,负面感知最强;天河区和广州其他区居民对广交会社会影响的正面感知相对较弱,负面感知相对较强;而越秀区的居民对广交会的正面感知最强,负面感知最弱。第三,在广州居住年限越长的居民对广交会社会影响的感知越消极。第四,文化程度越高的居民,对于广交会社会影响的感知越消极;第五,收入方面,居民月均实际收入越高,对个人收益感知越弱;第六,在相关行业工作的居民的个人收益感知比不在相关行业内工作的居民感知更强烈。  相似文献

本文将主客观评价法相结合,对北京市紫竹院公园视觉景观质量影响因素进行分析。课题组实地评价并拍摄照片,室内请评判者给照片打分评出美景度分值,请专家对主观性因子评价,与实地评价结果做一致性检验;对两种方式获取的数据进行方差分析、相关分析,并建立线型回归模型。结果表明:主观性因子的实地评价和室内问卷评价结果具有一致性;专业背景不同不影响评判者对景观美景度的评判结果;美景度与区内因子呈正相关,与区外因子呈负相关;区内的3个因子更能影响对景观的评判,其中,自然景观所占比例影响最为显著。  相似文献

河南省县域贫困程度及影响因素分析   总被引:1,自引:0,他引:1  
贫困地区的地理识别,是区域扶贫政策精准、有效实施的前提。以经济指标衡量河南省县域相对贫困程度,并借助有序logit回归模型分析社会经济发展、自然条件、区位交通、历史基础4类变量16个影响因子对区域贫困状况的影响程度。分析发现,河南省县域综合经济发展水平存在较大的区域差异,经济发展水平相对较低的县域多分布在豫西和豫东南,且区域内存在部分潜在贫困县。回归分析结果表明,工业化水平、居民储蓄水平、气温、湿度、到最近城市的距离、国道道路密度、期初经济水平7个因子对县域贫困程度影响显著。地区扶贫政策实施过程中,在重视经济因素的减贫效应时,也应重视自然因素的致贫效应,政府主导,因地制宜,逐步实现区域协调发展。  相似文献

Thanks to pioneering work within anthropology, students of international migration acknowledge that most immigrants do not sever their ties with the homeland, but rather maintain them through a variety of cross‐border relationships. While scholarly work has proliferated, since the early 1990s, over the transnational economic and political activities of immigrants, to date, only few analysts have examined the religious practices with which immigrants sustain memberships in multiple locations. In addition, most available studies on transnational migration has dwelled on qualitative methods, such as participant observation, focus groups discussions and in‐depth interviews with a handful of informants, with little or no inclination towards the quantitative measurement of key variables implicated in the process. The prevalence of ethnographic methods in this area of research has, quite understandably, engendered charges of exaggeration, given the tendency of such techniques ‘to sample on the dependent variable’, to borrow the phrase of Alejandro Portes. Using data collected from a survey among Ghanaian immigrant congregations in Toronto, this study seeks to statistically predict the propensity to engage in transnational religious practices by way of a binary logistic regression analysis. In addition, the study examines how the transnational religious activities of the sampled immigrants relate to, overlap with, and differ from other kinds of transnational practices they pursue.  相似文献

We consider the history of woodland clearing in central western New South Wales, Australia, which has led to the present highly cleared and fragmented landscape. A combined approach is used examining available historical land‐use data and using regression analysis to relate the pattern of cleared and wooded areas in the recent landscape to environmental variables, taking into account the contagious nature of clearing. We also ask whether it would be possible to apply a simple simulation modelling approach to reconstruct a credible historical sequence of clearing in the study area. The historical data indicate that annual clearing rates have varied substantially in the study area and selective tree removal (ringbarking and thinning) has been common. These findings make it unlikely that a simple simulation approach would replicate the spatial and temporal sequence of woodland loss. Our regression results show that clearing patterns can be related to environmental variables, particularly annual rainfall and estimated pre‐European vegetation type, but that patterns are dominated by contagion.  相似文献

Breathless: Schools, Air Toxics, and Environmental Justice in California   总被引:3,自引:0,他引:3  
The exposure of children to environmental disamenities has emerged as a key policy concern in recent years, with some analysts and activists suggesting that minority children are disproportionately impacted. Utilizing a dataset that combines air toxics at the census tract level with school-based demographic and other information, this article indicates disparate exposures for students of color in California schools and suggests that there may be negative impacts on one measure of academic performance, even after controlling for other factors usually associated with test scores. Policy implications include a special focus on school remediation and strengthening overall efforts to reduce emissions "hot spots."  相似文献

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.  相似文献

中国的快速城镇化推动了乡村发展转型与空间重构,农村居民对于土地退出、定居的想法正发生着变化。基于2014 年在南京市江宁区的问卷及访谈调查,本文探索了发达地区大都市边缘区中农村居民针对宅基地退出和未来定居的意愿。通过运用访谈资料和回归模型,本文发现村庄属性、一些个人主客观因子都影响着农村居民对于土地退出和未来定居的决策。本文还发现,相当多的农村居民倾向于在邻近小城镇定居,对宅基地退出普遍持负面态度。随着宅基地财产功能的提升、城乡一体化进程推进等方面的变化,关于宅基地流转制度的改革势在必行。  相似文献

In this study, we employed Geographical Information Systems and remote sensing techniques to investigate the impact of land‐use/cover change on land surface temperature (LST) in a rapidly urbanisation city, Kunming in south‐west China. Spatial patterns of LST and land use for 1992 and 2006 were derived from Landsat images to examine how LST responded to urban growth. Remote sensing indices were used to quantify land‐use types and employed as explanatory variables in LST modelling. The geographically weighted regression (GWR), a location dependent model, was performed to explore the influences of the spatially varied land‐use conditions on the LST patterns. Results revealed that rapid urbanisation in Kunming altered the local thermal environment, particularly in increasing the LST in the zone surrounding the urban core. Remote sensing indices demonstrated that water and vegetation played an important role in mitigating the urban heat island effect, while built‐up and barren land accounted for the increase in LST. The GWR improved the goodness‐of‐fit for LST modelling and provided insights into the spatially varied relationship between LST and land‐use conditions.  相似文献
