During the past 20 years, findings have indicated that nature plays an active role in helping people recover from stress and fatigue. Two of the most cited theories in this field are Rachel and Stephen Kaplan's theory of recovery from Directed Attention Fatigue in nature and Roger Ulrich's theory of aesthetic and affective responses to natural environments and stress recovery. One aim of the present study is to test whether being outdoors in a green recreational environment causes people to be more focused, compared to being in a room indoors (in line with hypotheses suggested by the Kaplans). Another aim is to test whether people experience stress reduction, i.e. as evidenced by changes in blood pressure and heart rate, if they are placed in an environment with many green elements (in line with hypotheses suggested by Ulrich). The overall study design is that of an intervention study. Fifteen elderly persons living at a home for very elderly people participated. Their powers of concentration, blood pressure and heart rate were measured before and after an hour of rest in a garden or in an indoor setting. Seven elderly people were randomly chosen to have their first series of tests in a garden, while eight elderly people had their first series of tests indoors. The results indicate that powers of concentration increase for very elderly people after a visit to a garden outside the geriatric home in which they live, compared to that after resting indoors in their favourite room. The results did not show any effects on blood pressure or heart rate. It is suggested that having a one-hour rest outdoors in a garden setting plays a role in elderly people's powers of concentration, and could thereby affect their performance of activities of daily living. One important factor in this study was that both the outdoor environment and the indoor environment at the home were highly valued by participants.  相似文献

This review paper contends that by paying attention to the quality of life issues raised by older people, planners may promote better places for all. Recent research in the UK that asked older people to identify quality of life criteria revealed that health, income, social networks, community participation, information, activities, home, neighbourhood and mobility are key areas where old age can be enriched. The paper argues that of these, home, neighbourhood and mobility are paramount for four reasons. Firstly, older people are seen as situated, even fixed, in domestic environments; secondly, society has responded to later life by creating age-segregated spaces; thirdly, lessening mobility may increase the importance of the local arena and fourthly the interplay between the self and the environment underpins or undermines independence. The significance of place means that planners, even more than other professionals, need to be age aware. Drawing on recent national and international research this paper contemplates what a more age-friendly place might be like and considers how issues of age can interact with the broader planning agendas of sustainability, cohesion and liveability to create places that promote well-being for every member of the community.  相似文献

The numbers of English public houses or “pubs” have reduced significantly in the last two decades. Politicians have called on the planning system to resist their closure but, at the same time, demand further controls over high-street bars. This paper explores the reasons for the decline and the rationale for supporting the continuation of the “traditional” English pub. Using evidence drawn from a wider study of the relationships between places and youth drinking cultures, the paper discusses young adults' use of pubs. While recognising the adverse effects of heavy drinking, arguments are put forward in support of the traditional pub as a site for restrained and responsible social interaction for young adults. The paper discusses the issues this raises for the UK planning system in the context of responsibilities for social sustainability and public health.  相似文献

为筛选水冬瓜叶抗炎镇痛活性成分,采用高效液相色谱(HPLC)建立不同采收期10批次水冬瓜叶药材指纹图谱,对其进行主成分分析,并基于皮尔逊相关分析法探讨不同采收期水冬瓜叶药材抗炎镇痛的谱效关系。结果显示,不同采收期水冬瓜叶药材HPLC指纹图谱中有17个共有峰,10批次药材的相似度为0.875~0.973。聚类分析将不同采收期水冬瓜叶药材分为3类。主成分分析共得到3个主成分。经皮尔逊相关分析,峰17、峰14、峰12、峰15、峰13、峰5、峰16和峰4可能为水冬瓜叶药材镇痛作用的物质基础,峰6、峰8(异槲皮苷)、峰11、峰7(金丝桃苷)、峰5、峰3、峰4、峰13、峰9和峰1可能为水冬瓜叶药材抗炎作用的物质基础。  相似文献
