This paper examines the viability of maintaining a heritage of low carbon comfort as an alternative to the energy intensive comfort regime of mechanical air conditioning. In many parts of the world, the carbon footprint of buildings is increasing significantly due to the widespread adoption of air conditioning. Current trends around indoor comfort are unsustainable, and alternative, less energy intensive comfort regimes need to be maintained or cultivated. To date, studies on this topic in heritage and preservation studies have focused on the architectural designs of ‘passive cooling’. This paper seeks to expand this conceptualisation of ‘cool living heritage’ to incorporate other forms of material culture and comfort practice.  相似文献

The cruise industry has seen its revenues more than double since the year 2000. Hence, it has become even more important for planners and managers to pinpoint those destination attributes that make a difference in satisfying cruise ship passengers. This is especially crucial since the extant literature established that visitors' overall satisfaction with the destination strongly influences intent to return or recommend the destination to others. The purpose of this paper is to explore how the satisfaction of cruise visitors regarding various destination attributes may relate to their satisfaction with the destination and how this may influence declared intent of repeat visits or intent to recommend the destination to those within their social and professional networks. This study is based on the data collected for the island of Oahu in 2013 in Honolulu, Hawaii. Our analysis makes use of the logistic regression, and our results indicate that distance deters passengers from repeat visits, whereas the influence of satisfaction with the destination is positive not only for revisits, but also for word-of-mouth recommendations. Satisfaction with attributes such as transportation, safety and prices strongly influences satisfaction with the destination, whereas satisfaction with other attributes such as on-shore activities or sightseeing tours were found not to be as influential. The results delineate the factors planners and managers should focus on in their efforts to increase visitor satisfaction with a destination and thereby increase the likelihood of repeat visits and positive word of mouth.  相似文献

Changes in riparian vegetation extent in northern Queensland, Australia were assessed using aerial photographs from 1944 and 2000. Change in riparian extent was recorded as vegetation gain or loss. Changes in density were recorded as vegetation thickening. Riparian forest coverage increased by 22 ha during this time period in the Mossman River catchment. A total of 124 ha of riparian forest were gained, while 101 ha of riparian forest were lost. A further 59 ha of forest increased in density over this time period. Clearing, changes in farm management practices and natural stream channel movement have been identified as three potential causes for these changes. Areas with little or no riparian vegetation were identified and categorised into priority levels for potential revegetation efforts.  相似文献

为加强博物馆藏品的预防性保护,需全面掌握博物馆馆舍内外空气质量的现状,对其进行评估,进而采取有效措施治理改善,妥善保护人类文化遗产。本馆采用美国普滤(Purafil)公司研发并提供的检测技术,在馆舍内外选定八个测试点进行了腐蚀试片测试。根据监测数据得知,本馆处于高浓度极具腐蚀性的二氧化硫气态物质的包围中,已造成对金属、纸张等文物的危害,治理改善收藏环境迫在眉睫。创造保存各类藏品的微环境空间,是治理改善博物馆收藏环境的有效手段。  相似文献

基于空气污染的环境公正研究在国际上受到较多关注,但在发展中国家、尤其是中国,相关研究较为缺乏。本文使用2010年河北省人口普查和空气质量数据,采用空间分析、描述性统计以及空间回归模型等方法对基于乡镇街道层面的空气污染和死亡人数的空间分布、社会分布及其关系进行研究。结果表明,河北省空气污染和死亡人数在城市和农村地区存在显著差异;基于乡镇街道层面,河北省的婴儿(1岁及以下)、老年人(60岁及以上)、失业者和省外农村流动人口更多地居住在空气污染比较严重的地区;婴儿、老年人、使用固体燃料或住房无洗澡设施的家庭户聚集的乡镇街道其死亡人数较多;空气污染与死亡人数之间存在显著的正相关。本研究旨在促进对中国环境公正与健康不平等的理解和认识,为发展更为公平、有效的环境健康政策提供科学依据。  相似文献

This paper explicates the role of community-level intermediaries in post-liberalized economic sectors. Focusing on nascent commercial markets for improved, smokeless cookstoves in southwestern Maharashtra, I describe how development is encountered by three analytic groups – artisans, female stove users and NGO field officers. This study highlights patterns of strategic intermediary action, or forms of brokering, used to negotiate the commercialization process for individuals involved in the fabrication, distribution and use of improved cookstoves. A close analysis of the mediating agent can strengthen theories on how individuals and communities encounter sector privatization and state retrenchment. This study reveals a diverse set of brokering activities and actors, and shows how intermediaries combine tasks associated with traditional conceptions of the political fixer and market broker by working within and between groups of market, village and state operatives to transform market supply chains. Mediating agents coordinate counter regulating activities within civil society in the absence of heavy state intervention and play a crucial role in activating and connecting community interests to latent neoliberal state resources.  相似文献

跟踪心理地理学相关网站信息和心理地理学情境主义“漂移”论代表性研究成果,开发一个二维的心理应激主观评测方法,通过情境下的深度访谈旨在从情境再现时空难暴露人群心理活动视角揭示其心理应激作用机制,将其具体概括为一个由时间过程特征和空间接近特征、个体心理应激行为和群体心理应激行为、消极心理反应和积极心理反应组成的相对应与互转化的组合范式,进而进行风险感知水平、心理意识力、区域差异的讨论,以说明情境“漂移”论对心理应激研究的支持。这项研究的特色在于将空难暴露人群心理应激机制研究建立在心理地理学情境“漂移”论的基础上,从而体现心理地理学的学科意义。  相似文献

Two China-based transportation geographers examine trends and developments revealed by the release of the most recent official data on traffic and airport capacity within mainland China's domestic air passenger transport system. The focus of the study is the uneven spatial distribution of airports and airport service hinterlands, as well as the hierarchical nature of passenger flows centered within the axis Beijing-Shanghai-Guangzhou (Hong Kong, Macau, and Taiwan are not included in the analysis). Among the questions investigated are the efficiency/balance within the system, as well as the extent to which the distribution of airports and air passenger flow volumes reflect basic patterns of economic and urban development within the country, and conform with a hub-and-spoke model.

A Hong Kong—based economic geographer presents an array of statistical data through 2007 that place Hong Kong among the world's leading financial, foreign trade, and air cargo handling centers. The paper's main focus is the economic relationship with Mainland China, which has grown and expanded since the change of the city's sovereignty in 1997. Included in the presentation is a review of economic integration before and after the handover by the UK to China, the pattern of cross-border investments and foreign trade, the growth of the logistics and tourism industries, and the challenges posed by changing economic relations, partly due to the rapid development of Hong Kong's hinterland. Journal of Economic Literature, Classification Numbers: O16, O18, O20, R11. 2 figures, 5 tables, 64 references.  相似文献
