Risk‐Utility Paradigms for Statistical Disclosure Limitation: How to Think,But Not How to Act

Risk‐utility formulations for problems of statistical disclosure limitation are now common. We argue that these approaches are powerful guides to official statistics agencies in regard to how to think about disclosure limitation problems, but that they fall short in essential ways from providing a sound basis for acting upon the problems. We illustrate this position in three specific contexts—transparency, tabular data and survey weights, with shorter consideration of two key emerging issues—longitudinal data and the use of administrative data to augment surveys.     

建设项目全程造价控制分析

工程造价控制贯穿项目建设全过程,建设项目造价控制存在很多问题,要抓好各个阶段的造价控制,尤其是设计阶段的造价控制.     

财政透明度的限度与效率:对一个分析框架的诠释

推进财政透明度是一个循序渐进的过程,需要关注披露信息的限度与效率。当前我国社会正处于转型期,财政透明度要避免陷入"过犹不及"的误区。因此,要以改革政府预算制度为契机,通过建立与完善规范的预算报告制度,搭建公民参与的平台,构建高效率的公共财政治理机制。     

解析地勘单位改革发展的三大体制性障碍

总体上看,十多年来地勘单位的改革方向是正确的,成效是显著的,但还存在一些突出的深层次问题.主要表现在三方面:一是地质找矿成果交易的有限性;二是地勘队伍"戴事业帽子、走企业路子"的局限性;三是地勘单位经营实体管理的不规范性."十二五"是国有地勘单位改革发展的关键时期,地勘体制机制改革将进入"深水区".认清地质工作体制障碍、事企混合运行体制障碍、内部产权管理体制障碍等三大体制性障碍,对做好地勘体制机制改革制度设计具有积极意义.     

能量收集无线传感器网络中的排队分析

在能量收集无线传感器网络中,节点可充电电池的容量和缓存大小会直接影响系统性能。因此,正确理解电池容量和缓存大小对性能产生的影响,对节点的设计具有重要意义。然而现有文献通常把数据到达和能量到达简化成泊松过程,无法刻画传感器数据和能量到达均具有突发性的实际情况。为了准确刻画数据和能量的到达过程,采用两状态Markov调制的on-off流模型描述数据和能量的突发到达过程,利用虚拟队列刻画数据缓存的占用情况和能量状态之间的相关性,并对虚拟队列进行排队分析,得到丢包率和平均延迟的表达式。通过数值研究和仿真验证了不同数据缓冲区大小、电池大小对传感器性能的影响,并针对不同数据到达突发度提出了缓冲区大小和电池大小的设置建议。     

WTO争端解决规则的完善能走多远

世界贸易组织争端解决制度是对关税与贸易总协定时期争端解决制度的变革。世界贸易组织成员和学术界肯定其运行效果的同时,也提出了一系列的完善主张和建议。对这些完善主张和建议的分析表明,从关税与贸易总协定时期演变而来的世界贸易组织争端解决制度与世界贸易组织成员权利义务的特征是紧密联系的,不可能突破权利义务双向性、违法措施既往不咎的基本理念和制度。应充分利用这一多边制度,捍卫双边权利、寻求双边救济。     

某些财务比率存在的不足与改进

On Solving the Multirotational Timber Harvesting Problem with Stochastic Prices: A Linear Complementarity Formulation

This article develops a two-factor real options model of the harvesting decision over infinite rotations assuming a known stochastic price process and using a rigorous Hamilton–Jacobi–Bellman methodology. The harvesting problem is formulated as a linear complementarity problem that is solved numerically using a fully implicit finite difference method. This approach is contrasted with the Markov decision process models commonly used in the literature. The model is used to estimate the value of a representative stand in Ontario's boreal forest, both when there is complete flexibility regarding harvesting time and when regulations dictate the harvesting date.     

The Warsaw limit: medieval unbreakable and unconscionable

The role of the Warsaw Convention in the modern world is increasingly under scrutiny. This paper focuses on the carrier's right to limit its liability under Warsaw as amended by the Hague Protocol, and examines three questions in particular. First, what are the origins of limitation of liability? Second, can one can ever really hope to break the limit under Article 25 of the Warsaw Convention? Third, can we really justify limiting passenger claims any longer? The answer to the first question is ‘medieval’ and the (not unsurprising) conclusion on the second and third questions is ‘no’ to each. The notion of breaking the limit is a chimera. And the notion that the present regime of limitation against passenger claims under Warsaw should continue to exist into the 21st century is, to the author's mind (and others), unthinkable. The industry must address the disquiet regarding limitation of passenger claims before the momentum to sweep away all forms of limitation becomes unstoppable.     

所有权社会化的演变与思考

所有权社会化是近现代民法的一种发展思潮,它是西方社会对所有权神圣与绝对不受限制的反思结果,其主要表现在所有权负义务,受到公共利益的限制,因此,所有权社会化具有一定的历史合理性。我国物权法对所有权也相应作出了规定,但由于长期以来对个人私有财产保护缺乏明确法律规定,同时公共利益本身又难以明确界定,因此,应当对所有权社会化给予合理限定,以防止其对个人私有财产的侵犯。
