纳米铁强化的混凝-沉淀-过滤工艺对典型印染废水中有机物去除

以东江流域某典型印染企业尾水为研究对象,将混凝剂与少量的纳米铁进行复合投加,再结合多介质过滤器对印染尾水进行深度处理实验研究.结果表明,新型混凝剂HPAC-9对极性有机物具有较强的去除能力,但对非极性或弱极性有机物去除效果不很理想.通过将纳米铁与HPAC-9复合投加并结合多介质过滤工艺,对印染企业尾水中的有机污染物进行...     

Using corporate social responsibility benchmarking framework to identify and assess corporate social responsibility trends of real estate companies owning and developing shopping centres

Shopping centres that include retail activities have come in for criticism as to their environmental, architectural and social impacts. However, the sector has been applying corporate social responsibility (CSR) practices. In an attempt to identify the best practices regarding CSR and trends therein we developed a CSR benchmarking of companies from the real estate sector owning and developing shopping centres. Based on information from websites, annual, environmental and sustainability reports, and customer services department’s information, in 2004 and 2010, a comparative CSR benchmarking was performed on 23 real estate companies with shopping centres based in Europe, China, Australia and the USA. The CRS benchmarking framework focused on reported CSR practices and included categories and sub-categories of evaluation in four domains: (1) external results, (2) internal results, (3) management processes and (4) learning and innovation. The framework was inspired by the sustainability balanced scorecard structure. The United Kingdom real estate sector’s companies studied did relatively well when evaluated by the framework used in this study. The highest ranked real estate companies applied sustainable or environmental buildings standards and did show a commitment to transparency and CSR disclosure. The positive evolution of CSR practices in the 23 companies studied in 2004 and 2010 may reflect efforts to improve competitiveness and the reputation of the companies with shopping centres through CSR initiatives.     

The social impact of natural hazards: a multi‐level analysis of disasters and forms of trust in mainland China

This study aimed to assess the multi‐level effects of natural hazards on trust in Chinese society. Drawing on the Chinese General Social Survey conducted in 2012 and provincial disaster damage records, it examined the association between individuals’ past experiences of disasters and province‐level damage (measured by the number of affected people, deaths, and economic loss) and various forms of trust: in‐group; out‐group; generalised; and political. The findings indicate that Chinese individuals with experience of disasters have higher levels of out‐group trust but lower levels of political trust. Similarly, at the province level, damage owing to disasters over the past three years (2009–11) positively impacted on residents’ out‐group trust while negatively affecting their political trust. However, when provincial damage was aggregated for disasters over the past five years (2007–11), which included the devastating Sichuan earthquake on 12 May 2008, only total deaths had a positive effect on generalised trust.     

生态社会主义及其双重价值研究

生态社会主义是当代西方一种具有重要影响的左翼社会思潮,它致力于生态原则与社会主义的结合,要求超越资本主义与现存的社会主义模式,主张在对资本主义进行批判和建议的基础上,建立新的绿色社会、生态现代化的社会和全面发展的社会。生态社会主义具有历史的进步性与理论和实践上的局限性双重社会价值,我们应当汲取生态社会主义的积极思想,为中国生态文明建设提供有益借鉴。

Scapegoat Ecology: Blame,Exoneration, and an Emergent Genre in Environmentalist Discourse

This essay identifies and examines scapegoat ecology, an emergent genre in online environmental discourse. In scapegoat ecology, a public of environmentally minded individuals focuses attention and vitriol on a single person for being particularly harmful to the environment. This essay argues that such discourse deflects attention from more complex and systemic environmental factors and implicitly exonerates the broader community, assuring it of its own environmental commitments while excusing it from further ecological action. The essay describes the form and appeal of scapegoat ecology, then provides a series of illustrative case examples before highlighting the implications of such discourse for both environmental communication and broader social/political conversations.     

Are national biodiversity strategies and action plans appropriate for building responsibilities for mainstreaming biodiversity across policy sectors? The case of Finland

The Convention on Biological Diversity's national biodiversity strategies and action plans (NBSAPs) are major mechanisms for mainstreaming biodiversity into national policies. This article examines whether and how the NBSAPs contribute to mainstreaming biodiversity across policy sectors in Finland in order to halt biodiversity loss. We have developed an innovative analytical framework where the concept of responsibility addresses how motivations for mainstreaming can be built, and the concept of social learning outcomes addresses the extent of institutional changes for biodiversity. The Finnish NBSAP processes have been able to build diverse forms of responsibility (liability, accountability, responsiveness and care) in different policy sectors by providing new knowledge, careful process design and developing institutional linkages. Despite pro-biodiversity outcomes in the targeted policy sectors, the responsibilities do not diffuse from the environmental administration to other policy sectors to a sufficient extent. Closing this ‘responsibility gap’ is a key challenge for building effective environmental policies.     

Urban sustainability – a segmentation study of Greater Brisbane,Australia

Setting universal goals for sustainability is problematic and may hinder the adoption of sustainable pathways as different sectors of society often have differing opinions on not just what sustainability means for them, but also what is of priority to them. This paper tests a set of psychographic, behavioural, lifestyle and social identities to segment the public on sustainability. We evaluate general knowledge, apply social-choice tools to identify public priorities, and then apply segmentation to reveal broad strata of community profiles around these choices. We discuss our findings in the context of moving beyond knowledge on sustainability and general public choices, to more nuanced messaging and engagement that respects differences in sustainability orientations. We suggest that by focusing on what matters most for different segments of society, there is potential to design effective processes to engage with people and acquire better ownership of sustainability.     

Opponents,waverers or supporters: the influence of place-attachment dimensions on local residents' acceptance of a planned biosphere reserve in Austria

A supportive attitude of residents towards protected areas is crucial for successful implementation and management, particularly in densely populated regions such as Central Europe. While previous studies have revealed that emotional and cultural drivers, as well as information level and group membership, can influence attitudes towards protected areas, the effect of place-attachment dimensions remains unclear. A postal survey among local residents (N = 460) explored factors influencing attitudes towards the Lungau (-Nockberge) Biosphere Reserve in Austria before its official recognition. Results indicated societal support throughout all socio-demographic strata. A logistic regression showed that, besides socio-demographics and information level, place attachment had a significant influence on the acceptance of the biosphere reserve. Supporters and opponents showed both high place identity and dependence, while waverers scored low on these dimensions. Results indicate that place attachment is relevant for the design of participatory processes as well as for developing management policies for biosphere reserves.
