Exploring the Association of Communication Satisfaction with the Oil and Natural Gas Industry and Risk Perceptions of Shale Energy Development     

Gene L. Theodori  Richard S. Bello 《社会与自然资源》2019,32(7):841-847

Despite the vast literature on shale energy development, surprisingly little empirical research has been conducted on the shale energy communicators, communication practices, and community outreach programs. Using data drawn from a random sample of individuals in two counties in the Eagle Ford Shale region of south Texas, we present a newly-constructed unidimensional scale that can be used to measure stakeholders’ level of satisfaction with the oil and natural gas industry’s communication performance. We then examine the relationship between individuals’ level of communication satisfaction with the oil and gas industry and their perceptions of risk in regard to shale energy development in the Eagle Ford Shale. We find substantial support for the hypothesis that communication satisfaction with the oil and natural gas industry is negatively associated with risk perception. We conclude the paper with several suggestions for future research.  相似文献   

澳门居民对“自由行”政策支持意向研究:地方依恋的调节作用     

胡孝平  李玺 《世界地理研究》2019,28(2):179-190

居民态度是影响旅游地持续发展的关键因素。借助态度ABC模型的标准学习层级理论,运用结构方程模型研究澳门居民对自由行政策支持意向的形成机理,并对地方依恋在其中的调节作用进行验证。结果表明：澳门居民对自由行政策支持意向主要受正面影响感知和积极情感的影响,澳门居民对自由行政策的经济与社会作用感知能激发其对旅游发展的满意感,并抑制对内地自由行游客的厌恶感,社会成本感知将导致居民对自由行游客的厌恶感,居民满意感对其支持行为意向有显著正向影响,地方依恋在澳门居民态度形成过程中发挥部分调节作用。根据研究结论,提出了提升澳门居民对自由行政策支持意向的管理举措。  相似文献

COMPARATIVE STUDY ON RESIDENTS＇ PERCEPTION OF TOURISM IMPACT AT TOURIST PLACES—A Case Study of Xidi, Zhouzhuang and Jiuhua Mountain     

SUQin CAOYou-hui LINBing-yao 《中国地理科学(英文版)》2005,15(1):70-79

Based on the questionnaire investigation, the authors make a comparative study on local residents‘ perception of tourism impacts in Xidi, Zhouzhuang and Jiuhua Mountain. The result shows that residents of the three places tend to have strong and consistent perception of its positive economic, socio-cultural and environmental impacts, but distinctly diverse ones of its negative impacts. Residents in Xidi and Zhouzhuang also have noticeable perception of its negative environmental impacts while those in Jiuhua Mountain have weaker perception of them.The research confirms the fact that residents are more liable to have positive perceptions at the early stage of the life cycle of the tourist places. The authors conclude that there exists a nonlinear relationship between residents‘ perception and tourism development stages, and that tourism socio-cultural impact may appear at an early stage of tourism development instead of being no universal.  相似文献

电子地图的色彩配合实验     

陈毓芬 《测绘学院学报》2000,17(1):53-56

在地图的色彩设计中,设计人员不仅要考虑色彩单独使用的效果,而且要考虑地图上各素的色彩配合,即各种色彩在图面上的整体感受效果。电子地图由于有极大的色彩选择空间,背景色不局限于白色,因而选色、配色比纸质地图更加复杂。用哪种简称颜色作为背景视觉效果较好？图面上各要素的色彩如何配合？针对这两个问题,作者设计了电子地图的一个色彩感受实验－色彩配合实验,利用自编的电子地图视觉感受测试构件（ＴＥＶＰ）进行了实验  相似文献   

Public perceptions of sharks: Gathering support for shark conservation     

《Marine Policy》2014

With increasing evidence of the destructive impacts of human activities on the ocean there is a growing call for stronger public engagement in marine governance. An understanding of marine issues and pro-environmental values are key elements that influence an individual׳s engagement in conservation and pro-environmental behaviour. This paper presents a study on public perceptions of sharks and shark conservation in the UK. The study investigated knowledge of and attitudes towards sharks of a group of individuals with a clear interest in the marine environment, as well as possible factors that might influence their perceptions of sharks, in order to make recommendations on how to foster engagement in shark conservation. The key finding was that important prerequisites for engagement in shark conservation exist among parts of the UK public. However, this does not seem to be enough to motivate actual engagement. The study discusses a number of specific challenges with regard to sharks which might be influencing the way in which society connects to shark related issues. It concludes with priority recommendations for further investigation into potential catalysts for public engagement in shark conservation.  相似文献   

基于城市园林树木景观三维模拟的绿视率估算方法     

江锋  唐丽玉  林定  陈晓玲  冯先超  陈崇成 《地球信息科学学报》2021,23(12):2151-2162

城市生态景观功能主要是绿色植物对人的视觉作用。绿视率被认为是一种比较好的衡量绿色空间视觉感受的描述因子。目前绿视率的估算主要基于静态的图像或者街景数据,而绿视率是一种动态的量,不同视点有不同的值,且植物是生长变化的。因此,本文提出一种基于数据和模型综合驱动的园林树木三维模拟景观的绿视率计算方法,其利用虚拟地理环境、虚拟植物等技术,通过道路、建筑物等硬质景观数据和树木模型驱动,建立城市园林树木三维景观;根据视觉成像原理,构建虚拟相机,模拟不同视点园林景观的视觉图像,然后识别表征植被信息的像素,从而计算绿视率。本文研发了园林树木景观三维模拟及绿视率估算原型系统,并以城市道路树木景观为例,模拟分析了机动车道中车辆乘客可获得的绿视率,与街景图像提取的绿视率值相近。该方法和系统可用于包含时间变量的不同生长阶段园林树木景观的绿视率评估,支持交互设置不同的视点参数,估算城市任意位置和任意方向的绿视率,评价过去、现在和未来的园林景观绿化质量,以人的视觉感知角度为城市绿地规划提供参考。  相似文献   

Fishers' perception of a multiple-use marine protected area: Why communities and gear users differ at Mafia Island,Tanzania     

《Marine Policy》2014

This study examined the perceptions of fishers from two fishing communities with differing use histories and involvement in the long-standing (16 yr) multiple use Mafia Island marine protected area (MIMP), Tanzania. A randomly distributed questionnaire indicated that 94% of fishers believed that without the MIMP, there would be overfishing, dynamite use, destroyed habitats, and few fish. Fishers were more positive about core zones (no-take fishery closures) than general use zones (areas allowing selective fishing) as a consequence of increases in fishing pressure. Those that reported increased catches and sizes of fish since the creation of the MIMP were more likely to agree with present zone locations and more positive in general about fisheries and conservation planning. Most thought that fish size and gear restrictions were preferable to permanent closures. Perceptions differed among communities and gear users. Community and gear type explained 46% of the variance in responses about the perception that fisheries and conservation are compatible goals. Somewhat surprisingly, these effects were more important than catch increases or involvement in MIMP-related activities. The differences in perception between communities may be partly attributed to different fishing histories. Multiple-use zoning provides a means to identify and resolve conflicts and achieve what are likely universal objectives for fisheries sustainability and conservation.  相似文献   

Spatial differentiation of tourism impact based on the perception of residents in mountainous valley resorts   总被引：1，自引：1，他引：0

Valley economy is a type of economy that comprehensively utilizes the natural economic and social resources of the region based on environmental protection. This economy utilizes the basic role of the market in disposing resources and achieving regional development and social progress. In this paper we studied the town of Yanqi, a valley resort that has developed tourism-based valley economy for several years in the mountainous area of Beijing. This research identifies the spatial differentiation of tourism-related economic, socio-cultural, and environmental impact and level of support for tourism according to the perception and attitude of residents of Yanqi. The research area was divided into three zones （i.e., core, transition, and peripheral） according to the standard proposed by Jaakson. The residents in all three zones showed a positive attitude toward the tourism industry, and the residents in the core zone had a stronger perception toward the impact of tourism. However, several items indicated the converse. Correlation analysis and analysis of variance were used to explore the correlative factors associated with the attitudes of residents toward the tourism industry. Results indicated major differences among the three zones. Multiple factors, including natural conditions, policies, scenic spots, dependence on the tourism industry, and external investment in the three zones resulted in the spatial differentiationof the perception and attitude of residents toward the impact of tourism.  相似文献
