论学校违纪处分的司法审查

受教育权是公民的一项受宪法保护的基本权利,当其受到不当行为侵害时理应得到司法的有效救济.学校具备行政主体资格,其违纪处分权是一种教育行政管理权,不当或违法的违纪处分侵犯了学生的合法权益.因此,学生不服学校违纪处分所产生的纠纷应该纳入行政诉讼受案范围.同时为了保障学校教育的自治权,行政诉讼应该遵守行政复议前置和司法审查有限两项原则.     

购买力平价理论的实证检验法综述

本文介绍了自 2 0世纪 70年代以来开放经济理论的基石———购买力平价及实际汇率的相关实证检验方法。以发达国家双边汇率作为样本数据进行检验 ,发现在样本期间足够长、样本数量足够多的情况下 ,PPP假设成立。此外 ,由于实际汇率对PPP的均值复归呈现出显著的非线性特征 ,今后的研究方向应当是建立非线性汇率动态模型。

国有银行贷审委的分离决策均衡激励约束机制探讨

目前的银行贷审委集体决策的体制往往导致贷款责任难以划分,集体负责实际变成无人负责。本文提出一个贷审委的分离决策均衡激励约束机制,使每个贷审委委员每次信贷决策均得到奖惩,从而解决贷审委集体决策无人负责的激励困境问题,决策基金帐户的设置则使贷审委委员无论调到何处,均需为他的每一次决策负责。     

Review: Food loss and waste in Sub-Saharan Africa

The research, development practitioner, and donor community has begun to focus on food loss and waste – often referred to as post-harvest losses (PHL) – in Sub-Saharan Africa. This article reviews the current state of the literature on PHL mitigation. First, we identify explicitly the varied objectives underlying efforts to reduce PHL levels. Second, we summarize the estimated magnitudes of losses, evaluate the methodologies used to generate those estimates, and explore the dearth of thoughtful assessment around “optimal” PHL levels. Third, we synthesize and critique the impact evaluation literature around on-farm and off-farm interventions expected to deliver PHL reduction. Fourth, we suggest a suite of other approaches to advancing these same objectives, some of which may prove more cost-effective. Finally, we conclude with a summary of main points.     

Structuration theory in accounting research: Applications and applicability

Ever since Giddens’ structuration theory (ST) was introduced into the accounting literature some 25 years ago, it has strengthened its position as one of the major schools of thought used to explore accounting as organizational, social and political phenomena. The purpose of this study is to review how ST has been applied, and can be applied, in this sizeable literature. Overall, the review of some 65 published papers, suggests that not only has ST contributed to challenge the assumptions of ‘inherent and functional’ features of accounting systems per se characterizing mainstream research, but also to develop other alternative theoretical perspectives. However, our review also suggests several limitations. These include that the accounting community has not really worked as a collective to develop a structurationist understanding of accounting practices, and that most researchers remain largely uncritical to ST as a theory. We also find that accounting scholars have not yet developed a mutual understanding of how to interpret ST (i.e. there are conceptual unclarities and even inconsistencies), or how to apply ST methodologically in empirical research. Based on these limitations, and the identification of a number of ‘black spots’ in the literature, we suggest several directions for future scholarly effort.
