Using clues from transaction cost economics this note develops an intertemporal agricultural household model to explain the demand-side credit rationing from formal financial institutions in agrarian economies. The model employs ex-ante transaction costs, namely search cost and negotiation cost to explain this phenomenon. The model shows that with market failure an agricultural household's production decision is not separate from its consumption decision. This is when the policy analysis household approach, which includes simultaneous decision making in production and consumption side, becomes essential.  相似文献

Policies developed at national levels can be unresponsive to local needs. Often they do not provide the rural poor with access to the assets and services they need to allow them to innovate and adapt to the ways that increased climate variability and change exacerbate challenges to basic securities – food, water, energy, and well-being. In development deficit circumstances, common pool resources are important for climate adaptation purposes. In order for climate adaptation actions to deliver resilience, local perspectives and knowledge need to be recognised and given due priority in formal planning systems. Basing formal adaptive development planning on local strategies can support and strengthen measures that people have been tested and know to work. Local climate adaptation through collective action can address current increases in climate variability, future incremental changes, and the need to transform existing systems to deal with qualitative shifts in climate. These types of adaptation can work in cumulative ways. The results of local adaptation collective action that have benefits of low rivalry between users while being highly inclusive can be considered “local public goods”. Evidence is beginning to emerge that when local governance systems facilitate high levels of participation in planning collective action for climate adaptation, and direct access to resources for implementing local plans, “local public goods” can be created and common pool resources better managed.  相似文献

To understand resilience to climate and environmental changes in fragile and conflict-affected societies is particularly important but equally challenging. In this paper, we first develop a conceptual framework to explore the climate-fragility-conflict and climate-resilience-peace nexus. Second, we discuss approaches to promote pathways from climatic changes to peace. We draw on the relevant literature and International Alert's experience in fragile and conflict-affected societies to stress the key role of resilience. To build resilience, climate, development, peacebuilding, and government actors would have to overcome bureaucratic and institutional barriers and cooperate across thematic and regional silos.  相似文献

Over the past few decades home garden research has emphasised the promotion of home gardening for nutritional and other welfare benefits for the poor in urban areas. Still, the urban communities who cultivate plants in their home gardens are in general represented as rather uniform groups, and no distinction is made in terms of caste, ethnic groups, or social class. This article asserts that social stratification represents an important aspect that needs to be taken into account while devising educational programmes and community projects for the promotion of home herbal gardens in urban areas.  相似文献

This article aims to provide knowledge and practical guidance to managing and implementing within the framework of endogenous development. The paper gives a theoretical overview of endogenous development, linked to issues of globalisation and poverty, and ongoing work among European institutions and academics that suggest shifts in Europe from exogenous to endogenous development approaches. It then makes a case for a paradigm shift – an African alternative to modernisation and development, namely endogenous development – using experiences with two NGOs in Ghana and Zimbabwe to locate theory in practice. The paper concludes with some empirical pre-requisites for conducting endogenous development with rural communities.

This article is prompted by the requests of my students at the University for Development Studies, Ghana, for knowledge and information, and practical guidance to managing and implementing within the framework of endogenous development. I start by giving a theoretical overview of the concept of endogenous development and link it with current issues of globalisation and poverty. I briefly mention current work among European institutions and academics that suggest shifts in Europe from exogenous to endogenous development approaches. Encouraged by such developments, I then make a case for a paradigm shift – an African alternative to modernisation and development, endogenous development. I bring to light the experiences with endogenous development in two NGOs – CECIK (Ghana) and AZTREC (Zimbabwe) – in order to locate theory in practice (praxis). I conclude by providing some empirical prerequisites for conducting endogenous development with rural communities, which demonstrate one way of conducting experimentation with farmers within the context of endogenous development.  相似文献

An algorithm incorporating multidetector computed tomography (MDCT), digital radiographs, and external examination was used to triage cases for noninvasive or complete autopsy after a natural disaster. The algorithm was applied to 27 individuals who died during or soon after the earthquake that struck the Republic of Haiti on January 12, 2010. Of the 27 cases reviewed, 7 (26%) required a complete autopsy to determine cause and manner of death. In the remaining 20 (74%), cause and manner of death were determined with a reasonable degree of medical certainty after review of circumstances, an external examination, and postmortem imaging by MDCT and digital radiography (noninvasive autopsy). MDCT was particularly useful in detecting skeletal fractures caused by blunt force injury which were not evident on digital radiographs. The algorithm incorporating postmortem MDCT can be useful in the triage of human remains for autopsy after a natural disaster.  相似文献

In many criminal and civil cases in China, the most commonly questioned documents are those written with gel pen ink. An important task for forensic document examiners is to identify whether two or more ink entries in one or more documents were written with the same ink type. The identification of the age of gel ink entries made poses an important and difficult problem for forensic document examiners. In this paper, the volatile components of gel ink were determined and the gel ink was classified by gas chromatography with a flame ionization detector. Calibration curves were created to express the relationship between the content of volatile gel ink components and the age of gel ink entries stored under natural and UV‐induced aging conditions. The correspondence between the natural and UV‐induced aging conditions was also established. The experimental results showed that GC was useful in the analysis of black gel ink and applicable for determining the relative age of gel ink entries under certain conditions.  相似文献

本文聚焦于城市化背景下的"抱团养娃"实践,深入探讨在抚育职责被"家庭化"的当下,抚育实践如何在一定程度上重新跨越"家庭"的边界。以社区共育为基点,妈妈们的努力既从私人层面上为在陌生城市中资源不足的小家庭找到更多社会支持,又在公共层面上带动孩子们以温度和情感重塑社区认同、黏合社会转型带来的制度缝隙,体现出独特的现实意义与支持力量。"以共同育儿为业"背后,是女性试图在既有的结构约束下找到被私人化的抚育照料重担与公共生活之间的连接点,在本研究中体现为共育支持网络的形成、共育友好空间的营造、亲子活动内容的生产和共育文化的建构四个方面。这为思考如何将"社会"重新带回抚育实践中提供了想象,也拓宽了对女性主体性的理解。  相似文献

ABSTRACT

Even though voters may irrationally blame the incumbent for natural disasters, democratic accountability can still hold if voters also reward the government for good responses. This article approaches the response-reward question by exploring the election impact of typhoon dayoff decisions in Taiwan. County mayors are responsible for deciding the dayoffs before a typhoon, so voters can easily and immediately observe the quality of the mayor's decision and fully attribute the outcome to him. Results combining 2005–2014 weather, election, and ten survey datasets show that a correct dayoff, which a dayoff was announced and the storm was tomorrow is harmfully strong, can significantly increase the incumbent's vote share. The effect is larger in the election year. Meanwhile, Taiwanese voters also slightly reward the incumbent for a bonus dayoff, which the storm is unexpectedly weak. Evidence also shows that mayors exploit the incumbent advantage by announcing more correct and bonus dayoffs.  相似文献

In 2010, the Government of Ontario, Canada passed the controversial Far North Act. The Act purportedly aims to promote land use planning and sustainable development while recognising Aboriginal and Treaty rights. There are, however, early warning signs that the Act could be a breeding ground for future conflict between Indigenous peoples and other stakeholder groups. This article adopts a ‘sons of the soil’ conceptual framework to explore the mechanisms that could give rise to the escalation of Indigenous vs. non-Indigenous conflict. The findings provide important insights for theorising the contentious politics around land and territory in diverse settler-colonial contexts.  相似文献
