Six years ago, the International Initiative for Impact Evaluation (3ie) launched a programme to promote and fund replication studies of impact evaluations in international development. We designed the programme with the objective of improving the quality of evidence for development policy-making, using replication research to both validate the results of published impact evaluations and build the incentives for more transparent and high quality research going forward. The programme’s focus is internal replication, which uses the original data from a study to address the same question as that study. This Journal of Development Studies special issue compiles the majority of completed 3ie-funded replication studies initiated in the first years of the programme. In all cases the pure replication components of these studies are generally able to reproduce the results published in the original article. Most of the measurement and estimation analyses confirm the robustness of the original articles or call into question just a subset of the original findings. These replication studies mostly focus on providing additional information about the impacts of the interventions – especially additional information that can be important for interpreting the articles for the purpose of policy-making.  相似文献

Fairy tales encapsulate the enduring myths of a culture, encoding the traditions and the moral values by which we like to think we live. (Garton 289) Ce que le monde fournit au mythe, c est un r el historique, d fini, si loin qu il faille remonter, par la fa on dont les hommes l ont produit ou utilis ; et ce que le mythe restitue, c est une image naturelle de ce r el. […] Le mythe ne nie pas les choses, sa fonction est au contraire d en parler: simplement, il les purifie, les innocente, les fonde en nature et en ternit , il leur donne une clart qui n est pas celle d explication, mais celle du constat. (Barthes, Paris, 230) What the world supplies to myth is an historical reality, defined, even if this goes back quite a while, by the way in which men have produced or used it; and what myth gives in return is a natural image of this reality. […] Myth does not deny things, on the contrary, its function is to talk about them; simply, it purifies them, it makes them innocent, it gives them a natural and eternal justification, it gives them a clarity which is not that of an explanation but that of a statement of fact. (Barthes, New York, 142-43)  相似文献

ABSTRACT

Drawing on the education production function literature, we examine the short-run impact of comprehensive education reforms in Barbados on primary school student outcomes. Using a variety of specifications to test the robustness of our results, we find modest and mixed changes in student test scores. Our findings are discussed in the context of management challenges that resulted from the need to coordinate a multi-faceted project in a rapidly developing nation; alignment of goals and schedules of two multi-national development banks, the Ministry of Education, Youth Affairs and Sports (MES), and the Government of Barbados; and, a very rapidly changing information technology environment that led, in part, to changes in planned capital improvements in schools, equipment needs, and had implications for teacher training.  相似文献

Research on social movement outcomes focuses on the publicly visible stages of government policymaking. It rarely opens the black box of government's translation of movement demands beyond the agenda‐setting stage and before their materialization into legislative bills. Using a bureaucratic politics perspective, we suggest that bureaucrats play a central role in translating movement agendas into concrete problems and policy solutions, which they tend to link with their bureaus' missions and existing programs. We further suggest that relative consensus among bureaucrats when coupled with politicians' disinclination to intervene in the translation process tends to advantage conservative interpretations of movement agendas. Conversely, interbureau confrontation and political intervention are associated with more radical policy responses. Empirically, we examine the responses of the Israeli government to the large‐scale mobilization, in 2011, surrounding the rising costs of housing and living. We build on archival research and interviews with senior bureaucrats located in 11 central‐government ministries.  相似文献

Mandible is the hardest and most durable bone of the skull exhibiting a high degree of sexual dimorphism. Especially ramus of mandible is subjected to greater stress than any other bone of the skull because of the process of mastication. This study has been performed to establish the osteometric standards for practical use in forensic context over Indian population using mandibular ramus. The sample consists of 116 mandibles of Northern Indian population (M:F; 92:24, mean age 37.4 years), collected from the Department of Forensic Medicine, IMS, BHU, Varanasi. Osteometric informations about five metric parameters (coronoid height, projective height, condylar height, and maximum breadth and minimum breadth of ramus) were taken with sliding calipers. These parameters were subjected to different discriminant function analysis using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.001 in all cases) with an overall accuracy of 80.2%, and coronoid height was the single best parameter providing an accuracy of 74.1%.  相似文献

The authors have developed a method for molecular-genetic analysis of DNA from isolated cells for the purpose of forensic medical diagnostics. The method is based on the use of the laser capture microdissection (LCM) technology in combination with typing of mitochondrial DNA. Optimization of the conditions for amplification of polymorphic mtDNA loci in preparations containing minimal amounts of the genetic material was accomplished at the initial stage of the work. To this effect, the two-round polymerase chain reaction was employed that allowed the amplified material to be accumulated in the amount sufficient for sequenation. At the next stages, the system thus obtained was tested on the cell model (using isolated cells of human buccal epithelium). It was shown that the proposed method is suitable for the analysis of specific mtDNA characteristics in a single human cell.  相似文献
