Ageism: A Factor in the Nutritional Vulnerability of Older People?

Unlike other population groups, the rights, needs and contributions of older people in developing countries are not well understood. With the absence of information about how to assess the nutritional status and vulnerability of older people, HelpAge International joined forces with the London School of Hygiene and Tropical Medicine in the early 1990s to launch a research programme. Seven years later some of the basic questions can now be answered but there remains much more to do.
Although older people are increasingly acknowledged as a vulnerable group in emergencies, NGO responses often fail to meet their needs. The question is whether there are real difficulties in service adaptation or whether ageism is one of the greatest barriers to the provision of appropriate services for older people.

Historical and contemporary indigenous marine conservation strategies in the North Pacific

Strategies to reduce, halt, and reverse global declines in marine biodiversity are needed urgently. We reviewed, coded, and synthesized historical and contemporary marine conservation strategies of the Kitasoo/Xai'xais First Nation in British Columbia, Canada to show how their approaches work. We assessed whether the conservation actions classification system by the Conservation Measures Partnership was able to encompass this nation's conservation approaches. All first-order conservation actions aligned with the Kitasoo/Xai'xais First Nation's historical and contemporary marine conservation actions; hereditary chief management responsibility played a key role. A conservation ethic permeates Kitasoo/Xai'xais culture, and indigenous resource management and conservation existed historically and remains strong despite extreme efforts by colonizers to suppress all indigenous practices. The Kitasoo/Xai'xais's embodiment of conservation actions as part of their worldview, rather than as requiring actions separate from everyday life (the norm in nonindigenous cultures), was missing from the conservation action classification system. The Kitasoo/Xai'xais are one of many indigenous peoples working to revitalize their governance and management authorities. With the Canadian government's declared willingness to work toward reconciliation, there is an opportunity to enable First Nations to lead on marine and other conservation efforts. Global conservation efforts would also benefit from enhanced support for indigenous conservation approaches, including expanding the conservation actions classification to encompass a new category of conservation or sacredness ethic.     

自主研发、技术引进与能源消耗强度——基于中国工业行业的实证分析

本文运用1998-2007年中国工业32个行业面板数据,将工业各行业研发总支出划分为自主研发、国外技术引进和国内技术转移三个部分,在估算自主研发存量和技术引进存量的基础上,研究了自主研发、技术引进对工业能源消耗强度的影响,并考察了能源相对价格、FDI的进入程度以及工业内部行业结构等因素.研究表明,自主研发和国外技术引进对能源强度的影响存在行业差异.自主研发对全工业行业和高能源强度行业的能源强度有显著负效应,对低能源强度行业的影响不显著;国内技术转移对全工业行业和低能源强度行业的能源强度有显著负的影响,对高能源强度行业的影响不显著;国外技术引进在所有样本中对能源强度的影响均不显著.研究还发现,在低能源强度行业中,自主研发并没有与国外技术引进互为补充共同促进能源强度的下降;在高、低能源强度行业样本中,自主研发没有与国内技术转移形成互补优势,有助于能源强度的下降.     

Public support for river restoration. A mixed-method study into local residents' support for and framing of river management and ecological restoration in the Dutch floodplains

In many European countries, accommodating water has become the dominant paradigm in river management. In the Netherlands, extensive river restoration projects are being implemented, many of which draw serious opposition from the public. To investigate the causes of such opposition, a comprehensive study of public attitudes towards river restoration was conducted in three floodplains, both before and after river restoration. The study combined quantitative questionnaires (N = 562) with open interviews (N = 29). This paper describes how local residents perceive the effects of river restoration on landscape quality and how residents and protest groups use landscape quality in combination with other arguments to strategically frame river management policies. Results show that measurement of the perceived outcomes of nature restoration needs to be complemented by a more dynamic type of research, focusing on the social processes of the framing of restoration plans. Theoretically, the paper aims to contribute to the development of a rigorous research strategy to study framing processes in environmental management, using a mixed-methods approach.

强化土著微生物处理硝基苯和苯胺污染地下水

以硝基苯、苯胺为主要污染物的污染地下水为研究对象,加入激活剂(乳糖、Na2HPO4、乳糖+Na2HPO4、乙醇、牛肉膏、蛋白胨)激活土著微生物,并考察其对土著微生物生长及硝基苯、苯胺降解效果的影响。加入激活剂3d后测各个水样的脱氢酶活性,对培养9d后的水样进行气相色谱/质谱(GC/MS)分析。结果表明,加入乳糖的水样中,其微生物相对增长率达157.2%,硝基苯、苯胺的相对去除率分别为14.90%和0.79%;加入Na2HPO4和乙醇的水样中,其微生物增长和硝基苯、苯胺降解情况均没有明显变化;加入乳糖+Na2HPO4的水样中,微生物相对增长率达180.3%,硝基苯、苯胺的相对去除率分别为24.20%和1.21%;加入牛肉膏的水样中,微生物的相对增长率为830.7%,硝基苯、苯胺的相对去除率分别为99.99%和99.67%;加入蛋白胨的水样中,其微生物相对增长率为686.0%,硝基苯、苯胺的相对去除率分别为99.33%和58.94%。GC/MS分析结果表明,加入激活剂后对氯苯胺、1-甲基-4-硝基苯等其他有机物的降解率均有提高。由此可见,通过激活土著微生物修复有机物污染地下水是可行的。     

Relationships between street characteristics and perceived attractiveness for walking reported by elderly people

Walking is important for the health of elderly people. Previous studies have found a relationship between neighbourhood characteristics, physical activity and related health aspects. The multivariate linear regression model presented here describes the relationships between the perceived attractiveness of streets for walking along and (physical) street characteristics. Two hundred and eighty-eight independently living elderly people (between 55 and 80 years old) participated in the study. Street characteristics were assessed along homogeneous street subsections defined as ‘links’. Positively related to perceived attractiveness of links were the following street characteristics: slopes and/or stairs, zebra crossings, trees along the route, front gardens, bus and tram stops, shops, business buildings, catering establishments, passing through parks or the city centre, and traffic volume. Litter on the street, high-rise buildings, and neighbourhood density of dwellings were negatively related to perceived link attractiveness. Overall, the results suggest that three main aspects affect perceived attractiveness of streets for walking, namely tidiness of the street, its scenic value and the presence of activity or other people along the street. The results are discussed within the context of these three aspects.     

Mobilising social energy against environmental challenge: understanding the groundwater recharge movement in western India

This paper explores a large-scale and growing popular movement to augment groundwater recharge in the Saurashtra region of western India, an area that has been facing acute water scarcity and other associated problems. As a social phenomenon, the movement is at an early stage of its development. However, it is interesting to study it for many reasons. First, even a decade after it began, it is still growing in scale and following. Second, it is entirely spontaneous and internally driven, necessitating no public resources or support. Third, early indications are that its social and ecological impacts are beneficial and highly significant. Fourth, the movement was catalysed and spearheaded by spiritual and religious institutions, which made ingenious use of non-economic messages and motivators in forging a new natural resource ethic based on a broad, collective rationality among movement members. It appears, however, that beyond a threshold, the movement acquired a logic and energy of its own which might fuel its future sustainability and growth. Finally, the movement has important lessons to offer because mobilising social energy on such a scale and intensity can perhaps be one of most effective responses to many of the environmental challenges the world faces today.
