African farmer-led irrigation development: re-framing agricultural policy and investment?

The past decade has witnessed an intensifying focus on the development of irrigation in sub-Saharan Africa. It follows a 20-year hiatus in the wake of disappointing irrigation performance during the 1970s and 1980s. Persistent low productivity in African agriculture and vulnerability of African food supplies to increasing instability in international commodity markets are driving pan-African agricultural investment initiatives, such as the Comprehensive Africa Agricultural Development Programme (CAADP), that identify as a priority the improvement in reliability of water control for agriculture. The paper argues that, for such initiatives to be effective, there needs to be a re-appraisal of current dynamics of irrigation development in sub-Saharan Africa, particularly with respect to the role of small-scale producers’ initiatives in expanding irrigation. The paper reviews the principal forms such initiatives take and argues that official narratives and statistics on African irrigation often underestimate the extent of such activities. The paper identifies five key characteristics which, it argues, contradict widely held assumptions that inform irrigation policy in Africa. The paper concludes by offering a definition of ‘farmer-led irrigation’ that embraces a range of interaction between producers and commercial, government and non-government agencies, and identifies priority areas for research on the growth potential and impact of such interactions and strategies for their future development.     

An agenda for the study of Public Administration in Developing Countries

Developing nations demand a different scholarly approach in the field of public administration. We advance an agenda for research that stands on four pillars. First, in the absence of easily accessible data scholars of developing world public administration must assemble it for themselves. Second, building and testing theory plays a paramount role because researchers face limited information. Third, in developing countries, multi‐national and non‐governmental organizations are often crucial and must be considered in studying public administration. Fourth, given the novelties and ambiguities researchers face, qualitative information must be integrated throughout the research process. Our article—and the articles in this volume—constitute a call for developing country research to contribute to the study of public administration writ large, informing our understanding of both developing and developed states.     

Economic effects estimation for the Eurasian Economic Union: Application of regional linear regression

This paper aims to provide a coherent analysis of the economic impact accession to the Eurasian Economic Union has had on the economies of current member states and what affect membership would have on the economy of Azerbaijan. By applying a Linear Regression Model we find that membership to this regional bloc has yielded minimal financial benefits for the existing members. However, for most states, accession has increased the trade deficit with Russia and that a membership would likely produce a similar negative outcome for Azerbaijan in addition to undermining national economic and energy policy making.

A群猪轮状病毒胶体金免疫层析试纸条的研制

为建立一种快速、简便的猪轮状病毒检测方法,采用柠檬酸三钠还原法制备胶体金颗粒,标记纯化的抗猪轮状病毒VP6蛋白单克隆抗体,在硝酸纤维素膜上喷加纯化的抗猪轮状病毒VP6蛋白多克隆抗体和羊抗鼠IgG,制成检测猪轮状病毒抗原的胶体金免疫层析试纸条。结果表明,所制备的试纸条用于检测猪轮状病毒感染的MA104细胞培养物,在检测线处出现红色反应带,未感染病毒的细胞培养物在检测线处未出现反应条带,上述培养物在质控线处均出现红色反应条带;进一步试验表明,试纸条检出病毒培养液(TCID50是10-6.25/0.1 mL)的最低限为1∶32稀释;用不同批次的试纸条重复检测,结果无差异;该试纸条不与相关的腹泻病毒猪传染性胃肠炎病毒、流行性腹泻病毒发生反应,所制备的试纸条具有一定的敏感性和特异性,重复性良好。     

牛D型产气荚膜梭菌肠毒血症间接ELISA诊断方法的建立

根据菌体蛋白可以刺激机体产生相应抗体的原理,建立了以产气荚膜梭菌粗提菌体蛋白为抗原的检测牛D型产气荚膜梭菌抗体的间接ELISA.结果显示,D型产气荚膜梭菌菌体裂解抗原最适包被浓度为50 μg/mL,最适包被条件为37 ℃ 1 h;被检血清的最适稀释度为1∶100,酶标二抗的最适工作浓度为1∶1 000,血清与酶标二抗的反应时间均为37 ℃ 1 h;最适封闭时间为37 ℃ 1 h;PBST稀释液中脱脂乳的浓度为30 g/L;底物最适反应条件为室温25 min;阴阳性临界值为0.032.对采集于吉林省延边州的100份牛血清样品采用建立的间接ELISA进行了检测;结果,阳性率为11.0%.经特异性试验、重复性试验和与琼脂扩散抗体检测法比较,采用裂解菌体蛋白为抗原建立的ELISA方法具有良好的特异性、敏感性和重复性.     

我国生态环境公益诉讼发展之进路

生态环境公益诉讼是贯彻“绿水青山就是金山银山”生态环保理念的司法实践,为打好污染防治攻坚战、实现生态环境治理能力现代化、健全公平正义制度保障提供了一条法治进路。历经十几年的发展,我国生态环境公益诉讼破除了旧有的法制藩篱,原告范围逐渐扩宽,司法救济不断强化。新时代,为进一步推进司法改革,完善生态环境公益诉讼制度,必须制定专门立法,强化检察职能,切实解决执行难问题,为建设美丽中国构筑坚固的法治屏障。     

论完善巡视监督的重要意义及现实路径

党的十九届四中全会首次将党和国家监督体系建设纳入中国特色社会主义制度体系,使其成为国家治理体系和治理能力现代化建设的重要组成部分。同时,对党内监督重要内容之一的巡视制度提出新要求,要求重点加强对党的高级干部、各级主要领导干部的监督,破解“一把手”监督和同级监督难题,强化政治巡视,推进纪律监督、监察监督、派驻监督、巡视监督统筹衔接,完善巡视整改落实情况报告制度等。新时代,我们党对巡视制度的高度重视,使普通党员干部和人民群众成为权力制约与监督的坚实基础和依靠力量,极大促进了党风廉政建设,具有重要意义。     

政治经济学批判视域中的恩格斯辩证法

围绕辩证法,一些西方学者常常得出恩格斯和马克思对立的观点。反驳这种错误观点有一条重要路径:恩格斯的辩证法并非局限于自然领域,而是以政治经济学批判的方式融入社会—历史当中。具体而言,它主要体现在三个方面:一是将辩证法奠基于现实经验的基础之上;二是准确阐释了马克思辩证法作为唯一正确的思想发展形式;三是进一步完善了政治经济学批判方法与对象的统一理论。这些贡献表明:一方面,在现实基础、基本形式、实践旨趣方面,恩格斯辩证法和马克思辩证法在根本上是一致的;另一方面,恩格斯对黑格尔辩证法有着深刻的理解,能够准确把握它与马克思辩证法的区别。这将有助于澄清对恩格斯辩证法的曲解和误解,也是对“矮化”恩格斯辩证法、制造恩格斯和马克思关于辩证法的思想对立的有力回应。
