This paper uses a computable general equilibrium (CGE) macro–micro model to explore the distributional effects of price reform in the electricity sector of Senegal. In the first part of the paper we analyse the distribution of electricity in Senegal by income quintiles, between 1995 and 2001. The analysis demonstrates that poor and rural households are not the main beneficiaries of the expanded network. The results of the CGE model show that direct price effects are weaker than general equilibrium effects on poverty and inequality. Moreover, compensatory policies tested can help attenuate some adverse effects.  相似文献

Agricultural intensification, or increasing yield, has been a persistent theme in policy interventions in African smallholder agriculture. This article focuses on two hegemonic policy models of such intensification: (1) the ‘Alvord model’ of plough-based, integrated crop-livestock farming promoted in colonial Zimbabwe; and (2) minimum-tillage mulch-based, Conservation Agriculture, as currently preached by a wide range of international agricultural research and development agencies. An analysis of smallholder farming practices in Zimbabwe's Zambezi Valley, reveals the limited inherent understanding of farmer practices in these models. It shows why many smallholder farmers in southern Africa are predisposed towards extensification rather than intensification, and suggests that widespread Conservation Agriculture adoption is unlikely.  相似文献

This article aims to critically examine Rwanda's security sector reform and disarmament, demobilisation and reintegration (ssr–ddr) process through a theoretical framework outlining four different models of peace processes in order to identify the sort of peace that can emerge from Rwanda's ssr–ddr approach. The author analyses how the Rwandan government has managed to keep the process ‘locally’ owned, while largely financed by external actors, despite strong criticism of its apparent lack of democratisation. The ‘genocide credit’, the Rwandan government's preference for national, rather than international solutions and its recent troop contribution to peacebuilding operations in the region are identified as the main reasons for this development. The paper argues that the peace emanating from the ssr–ddr process may be considered a hybrid form of state formation and state building, because of the local agency's preference for security and stability while simultaneously enjoying financial and technocratic support for its ‘liberal’ peacebuilding actions in the region.  相似文献

Urban development, and particularly the improvement of basic services delivery, is still approached in mostly technical terms by international development actors and municipalities of the Global South. Sanitation planning, for instance, remains the realm of engineers despite decades of evidence that conventional approaches focusing on infrastructure upgrading have failed to tackle socio-environmental challenges. Against this background, this paper explores sanitation planning in Mandalay, the second largest city of Myanmar. Here, the Asian Development Bank and a French consulting firm have seized the opportunity created by the country’s recent opening to embark with the municipality on a multi-million dollar scheme: the Mandalay Urban Services Improvement Project (MUSIP). Drawing upon insights from critical development studies, the paper argues that the MUSIP can be interpreted as an ‘anti-politics machine’ that ignored local needs and proposed disputable solutions to local sanitation challenges. The paper further explores how this machine jeopardised urban development in Mandalay more generally, and was eventually challenged by the municipality. The paper concludes that the case is not unique and illustrates how urban development is today being reshaped throughout Myanmar, while it also shows the continued relevance of the ‘anti-politics’ framework to understand contemporary urban development assistance projects.  相似文献

In recent years, voluntary associations and political organizations have increasingly relied on Internet-based mobilization campaigns, replacing traditional forms of face-to-face recruitment and mobilization. Within the literature, one can observe an intensive debate about the possible consequences of this transition. Most importantly, the question is whether political mobilization through the Internet is just as effective as mobilization in a face-to-face setting. In this article, we report on a mobilization experiment using both traditional (face-to-face) and modern (Web site) incentives for mobilization. The experiment was conducted among undergraduate students in Belgium and Canada and included a test of medium-term mobilization effects. Results suggest that the Internet is successful in transferring knowledge and raising issue salience among respondents, but neither experimental manipulation led to significant behavioral changes. We do not find any indication that among this experimental sample Internet-based mobilization would be less effective than traditional face-to-face forms of mobilization.  相似文献

Dental identification of unknown human remains continues to be a relevant and reliable adjunct to forensic investigations. The advent of genomic and mitochondrial DNA procedures has not displaced the practical use of dental and related osseous structures remaining after destructive incidents that can render human remains unrecognizable, severely burned, and fragmented. The ability to conclusively identify victims of accident and homicide is based on the availability of antemortem records containing substantial and unambiguous proof of dental and related osseous characteristics. This case report documents the use of digital comparative analysis of antemortem dental models and postmortem dentition, to determine a dental identification. Images of dental models were digitally analyzed using Adobe PhotoshopTM software. Individual tooth anatomy was compared between the antemortem and postmortem images. Digital superimposition techniques were also used for the comparison. With the absence of antemortem radiographs, this method proved useful to reach a positive identification in this case.  相似文献

Weight is often one of the few recoverable data when analyzing human cremains but references are still rare, especially for European populations. Mean weights for skeletal remains were thus documented for Portuguese modern cremations of both recently deceased individuals and dry skeletons, and the effect of age, sex, and the intensity of combustion was investigated using both multivariate and univariate statistics. The cremains from fresh cadavers were significantly heavier than the ones from dry skeletons regardless of sex and age cohort (p < 0.001 to p = 0.003). As expected, males were heavier than females and age had a powerful effect in female skeletal weight. The effect of the intensity of combustion in cremains weight was unclear. These weight references may, in some cases, help estimating the minimum number of individuals, the completeness of the skeletal assemblage, and the sex of an unknown individual.  相似文献

We report the case of a man who died twelve hours after ingesting powdered iboga root, commonly taken for its stimulant and hallucinogenic properties. Ibogaine and ibogamine were quantified in the powder ingested and the victim's body fluids by GC‐MS/MS after liquid–liquid extraction (Toxi‐tubes A®). The concentrations of ibogaine measured in the blood samples taken at the scene and in the peripheral blood, urine, and gastric fluid samples taken during the autopsy were 0.65, 1.27, 1.7, and 53.5 μg/mL, while the iboga content in the powder was 7.2%. Moreover, systematic toxicological analyses of biological samples showed the presence of diazepam and methadone in therapeutic concentrations. Death was attributed to the ingestion of a substantial quantity of iboga in the context of simultaneous methadone and diazepam consumption.  相似文献

In the early decades of the nineteenth century the small European societies in Madras (now Chennai) and Bombay (now Mumbai) were divided by disputes of such intensity that the authorities in London feared for the future of British power in India. The divisions were legal and social. In law, the Governors and the Supreme Courts of both cities contested the scope of their respective roles with the arguments focusing on the rights of Indians. Again and again, government took alarm at the ‘pro-Indian’ views of reforming judges. The debates were reflected in European social divisions, thereby making them all the more intransigent; legal allegiance became linked to social allegiance. It was this mixture of the legal and the social which gave the wives and other female relatives of the judges a role in the process of reform. Normally confined to multiple pregnancies and restrained social functions, the divisions in European life gave these women an opportunity to influence legal change. Without making official public statements they took part in the development of ideas about Indian rights.  相似文献
