This article examines the design and implementation of the Expanded Public Works Programme, drawing from the lessons of the Gundo Lashu programme on labour-intensive construction in the road sector. The aim of the study was to examine major barriers to the design and implementation of the programme. The article is based on the analysis of data that were gathered from the Gundo Lashu programme. The data were collected using a structured questionnaire, face-to-face interviews with the project participants as well as reviewing key secondary data from the project documents. The study found that the projects under the Gundo Lashu programme have clearly demonstrated the importance of labour-intensive approaches, especially in the road sector. However, these projects were constrained by a wide range of challenges, ranging from a lack of community participation to poor product quality and inadequate planning for sustainable financing.  相似文献

Statistical issues arising in modelling univariate extremes of a random sample have been successfully used in the most diverse fields, such as biometrics, finance, insurance and risk theory. Statistics of univariate extremes (SUE), the subject to be dealt with in this review paper, has recently faced a huge development, partially because rare events can have catastrophic consequences for human activities, through their impact on the natural and constructed environments. In the last decades, there has been a shift from the area of parametric SUE, based on probabilistic asymptotic results in extreme value theory, towards semi‐parametric approaches. After a brief reference to Gumbel's block methodology and more recent improvements in the parametric framework, we present an overview of the developments on the estimation of parameters of extreme events and on the testing of extreme value conditions under a semi‐parametric framework. We further discuss a few challenging topics in the area of SUE. © 2014 The Authors. International Statistical Review © 2014 International Statistical Institute  相似文献

基于绍兴实践的跟踪审计组织管理探析   总被引:1,自引:0,他引:1  
跟踪审计是践行免疫系统理论的有效方式。笔者结合近年当地开展跟踪审计的实践,力求从多角度对跟踪审计的组织管理进行探讨。文章首先分析了目前制约跟踪审计发展的一些因素,主要包括法律依据、人才支撑和风险防控等方面的欠缺。笔者认为推动跟踪审计深入发展,需要加强跟踪审计的组织管理,据此文章围绕跟踪审计计划的制定、目标的确定、方式的选择、力量的整合以及过程的控制等方面开展了详细的分析论述。文章还在加强跟踪审计组织管理基础上,就如何进一步优化跟踪审计管理效果进行了思考,提出了找准审计定位、强化技术支持和有效化解风险等观点。  相似文献

思想政治教育是公共危机管理的重要方式和手段,在高校危机管理中具有预防危机、规范导向、整合资源、稳定局势、修复秩序等功能。创新高校危机管理中的思想政治教育,这既是新时期高校有效治理危机和维护校园和谐稳定的必然要求,也是推进高校治理体系和治理能力现代化的重要课题。高校危机管理中思想政治教育创新应坚持以人为本、预防为主、组织动员、迅速反应的原则,并从强化师生主体地位、增强思想政治教育预防功能、推行思想政治教育网格化、改革思想政治教育方式路径等四个维度来展开。  相似文献

Previous literature calls for further investigation in terms of precedents and consequences of learning approaches (deep learning and surface learning). Motivation as precedent and time spent and academic performance as consequences are addressed in this paper. The study is administered in a first-year undergraduate course. Results show that the accounting students have a slightly higher score for deep learning compared to surface learning. Moreover, high intrinsic motivation and extrinsic motivation have a significant positive influence on deep learning. Next, deep learning leads to higher academic performance; surface learning on the other hand leads to lower academic performance. The effect of deep learning on performance still holds, when we control for time spent, gender and ability. Consequently we can conclude that a deep learning approach is much more than ‘simply’ spending a lot of time on studying.  相似文献

Objectives: Complexities in the neuropathic-pain care pathway make the condition difficult to manage and difficult to capture in cost-effectiveness models. The aim of this study is to understand, through a systematic review of previous cost-effectiveness studies, some of the key strengths and limitations in data and modeling practices in neuropathic pain. Thus, the aim is to guide future research and practice to improve resource allocation decisions and encourage continued investment to find novel and effective treatments for patients with neuropathic pain.

Methods: The search strategy was designed to identify peer-reviewed cost-effectiveness evaluations of non-surgical, pharmaceutical therapies for neuropathic pain published since January 2000, accessing five key databases. All identified publications were reviewed and screened according to pre-defined eligibility criteria. Data extraction was designed to reflect key data challenges and approaches to modeling in neuropathic pain and based on published guidelines.

Results: The search strategy identified 20 cost-effectiveness analyses meeting the inclusion criteria, of which 14 had original model structures. Cost-effectiveness modeling in neuropathic pain is established and increasing across multiple jurisdictions; however, amongst these studies, there is substantial variation in modeling approach, and there are common limitations. Capturing the effect of treatments upon health outcomes, particularly health-related quality-of-life, is challenging, and the health effects of multiple lines of ineffective treatment, common for patients with neuropathic pain, have not been consistently or robustly modeled.

Conclusions: To improve future economic modeling in neuropathic pain, further research is suggested into the effect of multiple lines of treatment and treatment failure upon patient outcomes and subsequent treatment effectiveness; the impact of treatment-emergent adverse events upon patient outcomes; and consistent and appropriate pain measures to inform models. The authors further encourage transparent reporting of inputs used to inform cost-effectiveness models, with robust, comprehensive and clear uncertainty analysis and, where feasible, open-source modeling is encouraged.  相似文献

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires.  相似文献

Self-efficacy influences students’ activities, effort and persistence, and it can help predict their motivation and academic performance. This study attempts to investigate the relationship between self-efficacy, preferred learning methods, and academic performance under different learning methods in a unique hospitality course setting. The results indicate that hospitality management students prefer a “learn by doing” approach instead of computer-based learning and lecturing. This study concludes that self-efficacy affects the academic performance in both lecturing and practical learning in hospitality education. However, students’ preference in terms of learning methods does not influence their academic performance. Emphasizing “learn by doing” in the hospitality higher education curriculum is recommended in addition to recruiting faculty members with extensive industry experience. Conversely, it is recommended that faculty find the means to increase students’ self-efficacy when adopting different teaching approaches.  相似文献
