Targeting vulnerability after the 2005 earthquake: Pakistan's Livelihood Support Cash Grants programme

The 7.6 magnitude (Richter scale) earthquake that struck northern Pakistan on 8 October 2005 was devastating. This paper gauges success in targeting vulnerable families during the transition from relief to reconstruction through cash assistance provided by the Livelihood Support Cash Grants (LSCG) programme. Families without a male member, with a disabled male member aged between 18 and 60 years or with more than five children, defined as vulnerable, were provided with USD 50 per month for six months via a bank transfer. The LSCG scheme enrolled around 750,000 families and selected 267,402 vulnerable families to whom it disbursed a total of USD 86.95 million. Using a community‐based survey, this paper assesses leakage and under‐coverage (exclusion). Approximately 30 per cent of families received the cash grant. However, only one in two was eligible for the benefit, and one in two deserving families was excluded. This is a matter of grave concern.     

Business recovery: an assessment framework

This paper presents a Business Recovery Assessment Framework (BRAF) to help researchers and practitioners design robust, repeatable, and comparable studies of business recovery in various post‐disruption contexts. Studies assessing business recovery without adequately considering the research aims, recovery definitions, and indicators can produce misleading findings. The BRAF is composed of a series of steps that guide the decisions that researchers need to make to ensure: (i) that recovery is indeed being measured; (ii) that the indicators of recovery that are selected align with the objectives of the study and the definition of recovery; and, where necessary, (iii) that appropriate comparative control variables are in place. The paper draws on a large dataset of business surveys collected following the earthquakes in Canterbury, New Zealand, on 4 September 2010 and 22 February 2011 to demonstrate the varied conclusions that different recovery indicators can produce and to justify the need for a systematic approach to business recovery assessments.     

Can the commons be temporary? The role of transitional commoning in post-quake Christchurch

ABSTRACT

In recent work on commons and commoning, scholars have argued that we might delink the practice of commoning from property ownership, while paying attention to modes of governance that enable long-term commons to emerge and be sustained. Yet commoning can also occur as a temporary practice, in between and around other forms of use. In this article we reflect on the transitional commoning practices and projects enabled by the Christchurch post-earthquake organisation Life in Vacant Spaces, which emerged to connect and mediate between landowners of vacant inner city demolition sites and temporary creative or entrepreneurial users. While these commons are often framed as transitional or temporary, we argue they have ongoing reverberations changing how people and local government in Christchurch approach common use. Using the cases of the physical space of the Victoria Street site “The Commons” and the virtual space of the Life in Vacant Spaces website, we show how temporary commoning projects can create and sustain the conditions of possibility required for nurturing commoner subjectivities. Thus despite their impermanence, temporary commoning projects provide a useful counter to more dominant forms of urban development and planning premised on property ownership and “permanent” timeframes, in that just as the physical space of the city being opened to commoning possibilities, so too are the expectations and dispositions of the city’s inhabitants, planners, and developers.     

高盐条件下染料酸性橙7的生物降解特性

对偶氮染料废水厌氧-好氧生物处理中的高盐度抑制生物活性和芳香胺自氧化问题,通过多种强化策略,考察了NaCl为100g/L时酸性橙7(AO7)的生物降解特性.结果表明,加入葡萄糖(0.5g/L)、蛋白胨(1g/L)和酵母粉(0.5g/L)有利于高盐条件下AO7的生物降解.进水中加入酸性红B对AO7的脱色有加速作用.耐盐污泥中加入蒽醌形成的蒽醌-污泥自固定化体系可以促进AO7脱色,当蒽醌浓度为100mg/L时,AO7最大脱色率约为92%.以活性炭毡作为生物载体,厌氧和好氧体系均可实现稳定运行,且体系污泥沉降性良好,脱色速率达26.67mg/(L×h),且可有效抑制脱色中间产物1-氨基-2-萘酚的好氧自氧化,使COD去除率始终保持在90%以上.

Changes in housing in Guatemala following the 1976 earthquake: With special reference to earthen structures and how they are perceived by disaster victims*

This paper reports on what has happened to earthen structures in 26 Guatemalan communities studied over a 4-year period since the 1976 earthquake. The data were obtained from three waves of personal interviews with 1472 randomly sampled household heads. The results show that adobe, which was the primary housing material before the earthquake was heavily damaged in that event. As a consequence the number of adobe structures and of other earthen structures has been drastically reduced. The people of Guatemala individually and because of agency housing programs have abandoned adobe as a building material and turned to concrete block and wood. Surviving earthen structures have not been improved substantially and remain with largely the same structural features as before the earthquake. The greatest improvement is in the use of comer posts or columns in the walls but most of these are made of untreated crude logs or lumber, subject to rot and termite damage. Little information on aseismic housing seems to have spread either within the earthquake area or in the unaffected areas surrounding it. A program to spread information on how to use adobe in aseismic designs needs to be conducted along with one to assist citizens to aquire the resources necessary to improve the earthquake vulnerability of houses.

应用极值理论研究台湾和华东地区中强地震活动的相关性

运用极值分布理论对1970～1999年间台湾和华东地区的地震资料进行统计性研究,得出其地震相应震级的复发周期[T(M)]、理论发震次数(η)和华东地区中强地震的发震概率阈值(PO)。通过对T(M)的同比分析,发现两地中强地震存在着较好的相关性。用以上研究的结果对华东地区5级以上地震的发震概率、发震时间和地震强度进行综合判定,效果较好。
