This article investigates off-farm work decisions by smallholder farm households. Using data on 1,101 households from Burkina Faso, it demonstrates that in addition to the usual household socio-demographic characteristics, remittances, access to information and beneficiary of specific training affect off-farm work decisions, as well as rainfall factors and idiosyncratic health shocks. Community characteristics such as accessibility and number of inhabitants are also key factors. While suggesting that off-farm work is less likely to be undertaken for accumulation purposes, these results have important policy implications. In particular, policy measures should consider each segment as a separate entity.  相似文献

International development agencies, with the help of the central government, support building state of art Bus Rapid Transit (BRT) in low-income Asian cities. However, BRT investment over indigenous modes of mobility is creating socio-political tensions at the local level. This article uses multi-level governance as a theoretical lens to examine the relationships among actors in BRT investment decisions in Bandung and Surabaya, Indonesia. The research finds that local stakeholders can distort national and supranational policy initiatives totally or in a way that while projects are delivered, they are of limited use to the local communities they intended to help.  相似文献

This viewpoint reflects on how to improve the process of introducing facilitated industrial symbiosis programmes (FISPs) to small and medium enterprises (SMEs) in developing countries. Although FISPs are a long-established industrial practice, their formal introduction to SMEs in developing countries has only recently begun, mostly through support from international development agencies. Based partly on anecdotal evidence from Gauteng, South Africa, we identify six key questions which need to be addressed to improve the process of facilitating FISPs.  相似文献

The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.  相似文献

对于自然资源,需要在利用与保护之间寻找到合适的平衡点,并以法律的形式将其确定下来。通过自然资源物权配置,把以对资源的用益为目的的各种物权形态,依照法律规定的条件和方式投入市场,最大限度实现国家所有权利益。同时,规范行政主管机关职责,完善行政管理的程序法律规范,将公法上的权力和私法上的权利相分离,使行政机关的宏观管理职能与自身部门利益相脱钩。  相似文献

Blood previously acidified with aqueous saturated ammonium chloride solution was extracted with ethyl acetate. The dried extract was subjected to acetonitrile–hexane partition. The acetonitrile portion was analysed for the presence of acidic and neutral drugs by HPLC–DAD (200 mm×2.1 mm I.D. microbore ODS-Hypersil column) and GC–FID (25 m narrow-bore×0.25 mm I.D. HP-5 column with 0.33 μm film thickness). The protocol was found to be suitable for both clinical toxicology (including emergency toxicology) and postmortem toxicology. At least 66 drugs of interest were unequivocally identified by RRTs (HPLC) and UV spectra (DAD) match while another 12 were unequivocally identified by double RRTs match (HPLC and GC). Quantitation was facilitated by incorporating calibration blood standards in each assay batch. The five drugs most commonly encountered in clinical blood specimens (1150 cases) were: paracetamol (47.4% of the cases); chlormezanone (6.6%), theophylline (1.74%), naproxen (1.65%) and mefenamic acid (1.56%). The following drugs were detected in toxicologically significant quantities in postmortem blood specimens (245 cases): phenobarbitone (1.22% of the cases), naproxen (0.82%), chlormezanone (0.82%), theophylline (0.82%), carbamazepine (0.41%) and paracetamol (0.41%).  相似文献

权利是它的所有者通过法律、道德、秩序或其他形式而获得的有利地位。实证性权利既包括制度性的经验事物如国家和契约,也包括观念性的现实事物如自由和习惯。由于无论国家还是契约,自由还是习惯,都有其不能脱离先在的权利来谈论的局限,因此,权利的来源往往被追溯到具有逻辑先在性的东西那里。传统自然法理论把自然权利看作是实证权利的前提,现代人权理论则否认有脱离制度安排的抽象权利。从地位而不是从来源出发来理解人权,是现代人权概念区别于传统自然权利概念的最大特点。  相似文献

二十世纪八十年代后,毒品在中国又开始死灰复燃。针对日益严重的毒品违法犯罪,国家制定了一系列法律法规,在禁毒斗争中发挥了巨大作用。但是,由于毒品问题的特殊性和我国国情,仅全国统一禁毒立法还不够,尚需地方立法的细化和补充。本文根据对天津毒品问题的分析和对其他省、市、自治区已有地方禁毒立法的研究比较,指出了制定天津地方禁毒立法的必要性,提出了天津禁毒条例的体系设想,力求为天津的禁毒立法提供某些启示和借鉴,推动我市地方禁毒立法进程。  相似文献

确定嫌疑人是否吸毒及吸食毒品的种类是打击毒品违法犯罪必不可少的程序。毒品检验是打击毒品犯罪的一个有力工具。可用于毒品检验的方法很多,检测的物质也不尽相同。本文着重介绍用酶联放大免疫分析法所能检测的毒品簇及具体检测物质。  相似文献
