Rehabilitation in Complex Political Emergencies: Is Rebuilding Civil Society the Answer?

The paper examines the challenge of rehabilitation from complex political emergencies (CPEs) and identifies a strategy that is characterised as a civil society rebuilding approach. It focuses on Somalia and a case study of a CARE project that aims to build the capacity of local NGOs. The paper argues that civil society in CPEs is simultaneously being undermined and contested by warring parties and emerging after state collapse. The scope of the paper is limited to one case study and that case study examines only a single aspect of civil society: national and international NGOs. The paper therefore presents tentative and preliminary results based on limited research. However, in reviewing the literature and presenting a way of approaching the subject, it aims to suggest a starting-point for developing a theoretical framework for such research. The paper finds that international agencies have tended to focus on civil society institutions simply as conduits for aid money and that this has tended to create organisations which lack downward accountability, are dependent on donors and are not addressing the wider roles for civil society envisaged in the approach. Rebuilding civil society does hold out the promise of giving non-military interests a stronger voice and starting a process of changing the aid delivery culture. Achieving these objectives, however, will be a slow and largely indigenous process and there is a need for lowered expectations about what outside assistance can achieve     

厌氧氨氧化微生物的吸附、包埋固定化效果初探

以活性炭、陶瓷生化环、陶瓷生化球、珊瑚砂、火山石和生化棉为吸附固定化载体,以海藻酸钠(SA)和聚乙烯醇(PVA)制成的SA、PVA、PVA-SA和PVA-SA-活性炭小球为包埋固定化载体,研究了厌氧氨氧化微生物固定化的脱氮效果.结果表明,吸附固定化的大部分处理和包埋固定化的部分处理均能维持较高的厌氧氨氧化活性.吸附固定化脱氮效率优于包埋固定化,其中,活性炭吸附固定化脱氮效果最好,初期可以提高活性达30%以上.通过对活性炭吸附固定化的中长期连续运行监测发现,活性炭固定化第6次反应过程的厌氧氨氧化活性是对照的3.5倍.因此,活性炭吸附固定化还具有稳定持续的中长期效应,不失为一条有效提高厌氧氨氧化活性的固定化途径.

基于农户行为的土地利用人工社会模型的构造与应用

为探讨人工社会在土地利用变化研究领域中的应用,研究创建了一个模拟土地利用变化过程的人工社会模型(LUC-ASM)。该模型以农户和农民为两类主体(agents),模拟分析不同社会经济条件和政策影响下,两类主体对自己承包土地利用方式的微观决策所可能产生的宏观效应及其时空变化特征。以鄱阳湖区一个现实村落为主要研究对象,以农户从事各类生产活动的行为特征为准则,利用LUC-ASM模型模拟未来30年内该村落土地利用变化过程。结果表明,未来这一地区土地利用的变化与人口增长结构调整方式、国家土地利用与环保政策、社会经济发展态势等因素密切相关;在城市化的影响下,该地区的农业劳动力将会出现短缺,农村土地有可能被撂荒,需要及早采用政策措施予以避免。总体而言,LUC-ASM模型能够形象地反映土地利用变化过程的微观驱动机理及各种社会经济与环境因素影响的宏观效应,有助于深化我们对人与自然环境相互作用的认识。

采用聚乙烯醇（PVA）包埋硝化效能良好的活性污泥制备固定化颗粒,针对不同初始氨氮浓度的模拟废水,基于序批式间歇反应器小试实验,探讨了包埋颗粒的传质效能与氮去除过程特性.实验结果表明：颗粒体积投加率为10%,实验水温为26~30℃,pH值为7.5~8.5,反应器DO浓度为4~5mg/L的条件下,各初始氨氮浓度（50~400mg/L）稳定期包埋颗粒最大氨氮去除负荷为61.8~242.3mgN/（L-particles·h）.包埋颗粒对氨氮的去除较符合零级反应动力学模型,其最大氨氧化速率（μ_max）为271.40mgN/（L-particles·h）,半饱和常数K_s为66.69mg/L,包埋颗粒内氨和氧的有效扩散系数（D_e）分别为0.467×10^-9m²/s、0.279×10^-9m²/s.SEM观察和比表面积测试结果表明,与新鲜颗粒相比,稳定期颗粒内部的比表面积和平均孔径增加.包埋颗粒,活性污泥,包埋颗粒与活性污泥混合3种体系对比实验表明,各初始氨氮浓度条件下混合体系可显著强化生物硝化与脱氮过程,并发生同时硝化反硝化现象.     

Relationships of the dimensions of sustainability as measured by the sustainable society index framework

This article presents a study of the interrelationships between the different dimensions of sustainability as measured by the sustainable society index framework. We examine the statistical relationships between the four indices making up the sustainable society index framework. The analysis uses the complete existing data set provided by Sustainable Society Foundation for the years 2006, 2008, 2010 and 2012 and for 151 countries. While the time period where data are available is quite short, we can make some preliminary observations about the apparent trends in the interrelationships of the different dimensions of sustainability. This study shows that the three dimensions of sustainability are far from all being synergic and positively correlated. There is a strong negative correlation between human well-being and environmental well-being. This is problematic from the point of view of the Brundtland Commission’s three-pillar definition of sustainability. However, the trade-off relationship between economic and environmental development measured by the economic well-being index and environmental well-being index is decreasing and the dimensions are becoming more de-linked. This trend is promising from the sustainability perspective.     

The design of decision-making: participatory budgeting and the production of localism

This paper examines participatory budgeting (PB) as an instrument of localism – the devolution of political governance with the aim to produce sustainable democratic communities. This will be achieved through a detailed exploration of the decision-making mechanisms for creating local governance through PB schemes designed and organised by the Cornwall Council (UK). First introduced in the UK by the previous Labour administration in 2008, PB has become a tool of the Conservative-Liberal Democrat coalition government and is central to the neoliberal ethos of Big Society and localism. In a time of rapid political change, we respond to Eaton's [2008. From feeding the locals to selling the locale: adapting local sustainable food projects in Niagara to neocommunitarianism and neoliberalism. Geoforum, 39, 994–1006, 996] suggestion that greater attention be paid to “the specificities of particular neoliberal projects” by focusing on the micro-politics of PB. We draw upon empirical evidence from PB pilot schemes run in rural Cornwall in 2008, examining the effect of “nudging” decision-making. Grounding this inquiry in the existing literature on neoliberal statecraft, this paper investigates the role of government technologies which seek to frame local governance using mechanisms of libertarian paternalism [Painter, J., 2008. European citizenship and the regions. European Urban and Regional Studies, 15, 5–19; Painter, J., 2010. Rethinking territory. Antipode: A Radical Journal of Geography, 42, 1090–1118; MacLeavy, J., 2008. Neoliberlising subjects: the legacy of new labour's construction of social exclusion in local governance. Geoforum, 39, 1657–1666]. We argue in this paper that neoliberal ideology has integrated the epistemology of behavioural economics. We draw conclusions commensurate with the outcomes of PB projects conducted in Latin America, namely that citizens can be steered towards making certain decisions. We assert that in order to direct decision-making successfully, governmental “top-down” frameworks and goals need to be married with local geographies and “bottom-up” local desires and aspirations, thereby enabling a “countervailing power” [Sintomer, Y., Herzberg, C. and Rocke, A., 2008. Participatory budgeting in Europe: potentials and challenges. International Journal of Urban and Regional Research, 32, 164–178] to develop. This power is exercised by a participating and scrutinising citizen that contribute towards, and balance, governmental practices of PB. With a wider governmental emphasis on designing or “architecting” choice in opportunities for local governing, there is now an even greater necessity to recognise the context of geography in local government community-orientated initiatives.     

Mapping civil society: the ecology of actors in the Toronto region greenbelt

ABSTRACT

Civil society’s potential as a force for solving complex societal problems – particularly those that require a challenge to the status quo – has provoked practical and theoretical interest, with its potential largely reliant on the perception that it is a ready if variable source of social capital resources. However, there are no guarantees that civil society will use its social capital for the greater good. Civil society encompasses a range of groups, some more inward-looking and oriented to private interests, and others more outward-looking and oriented to public interests. This divergent character of civil society was evident in the three campaigns for greenspace protection that eventually led to the creation of the Toronto region greenbelt, where civil society organisations (CSOs) from both growth and conservation camps contended for influence, each succeeding at different times. But over time (a time when state actors were increasingly in need of non-state partners to help solve complex governance problems), coalitions of environmental CSOs in the three campaigns – to protect the Niagara Escarpment, Oak Ridges Moraine and surrounding countryside – became more effective at influencing government to protect greenspace. A comparison of the coalitions using a framework based on key attributes of CSOs – missions and memberships – suggests that the environmental coalitions were more effective when they recruited more members with a diverse set of resources arising from both bonding and bridging social capital. In general, the more inclusive and public-interested the CSOs, the more effective the challenge to the status quo.     

Review and future of active disassembly

Disassembly has been widely accepted as a disadvantageous end-of-life activity, but with increasing pressures from directives, such as waste on electrical and electronic equipment, and with increasing pressures to become sustainable disassembly is becoming necessary. Current disassembly methods, including both manual and automated disassembly, need improvements to meet this necessity. This paper will introduce the improvements needed and suggest through literature the validity of active disassembly (AD) to provide these improvements. Past and current research will also be considered to provide a future path for AD. This future path for AD will consider a collaborative effort to solve problems with materials, environmental triggers and costs seen with AD.
