新贫困视域下乡村转型的困厄与重构路径

中国社会转型的重要背景之一是全球消费社会的到来。 这使得新穷人现象日渐凸显,并成为影响甚至主导整个社会转型的核心线索。 作为新穷人的典型表现,乡村新贫困既包括在城乡二元结构下,村民难以获得以城市生活方式为参照的社会公认生活水准而引发的结构性贫困,也包括由消费欲望激发的社会心理性贫困。 由此,乡村消费转型表现为如下困境:私人消费中,个体消费认同在地和脱嵌的困境以及家庭消费规范物质化和人伦的两难;集体消费中,消费品“上移冶和“下乡冶的悖论。 为应对这些困境,必须从消费角度,破解“新穷困冶的结构性和文化困境,实行新型城镇化和新农村建设并举。     

我国省级地方政府预算细化与腐败的关联性研究

预算细化会改变现有预算参与方的利益,减少地方政府的寻租腐败空间,从源头上预防腐败.基于我国31个省级地方政府的面板数据,可对预算细化的反腐败效应进行实证检验.研究结果表明:财政透明度与腐败呈显著的正相关;非税收入占财政收入比例的回归系数值为负数且不显著;财政分权与腐败也呈负相关且不显著;公务员工资水平与腐败呈显著的正相关.由此可见,为了提升预算反腐的有效性,应落实全口径预算,将政府的所有收支纳入预算,规范化管理非税收入;并完善财政分权体制,赋予地方政府实质性的财权和事权;同时要健全与完善追究机制、晋升考核机制等相关制度.

车用天然气储气技术

天然气用作汽车的代用燃料,具有储量丰富、价格便宜;辛烷值高、燃烧充分;低硫、低氮、无灰、环境污染少等优点。但是,目前的压缩天然气储气技术存在储气压力高、储气量小、续驶里程短等缺点,严重制约着天然气汽车应用领域的扩展。对5种车用天然气储气技术进行了分析讨论后,指出了吸附储存和近临界流体储存天然气技术在天然气汽车领域将有着广阔的应用前景。     

A new approach to statistical efficiency of weighted least squares fitting algorithms for reparameterization of nonlinear regression models

We study nonlinear least-squares problem that can be transformed to linear problem by change of variables. We derive a general formula for the statistically optimal weights and prove that the resulting linear regression gives an optimal estimate (which satisfies an analogue of the Rao-Cramer lower bound) in the limit of small noise.     

Comparison as a Universal Learning Action

This article explores ‘comparison’ as a universal metasubject learning action, a key curricular element envisaged by the Russian Federal State Educational Standards. Representing the modern learner’s fundamental pragmatic skill embedding such core capacities as information processing, critical thinking, robust decision-making, and effective problem solving, the universal learning action of ‘comparison’ has become a new professional challenge for educators, in terms of both understanding the underlying theoretical framework and ensuring that appropriate instructional models are deployed. The author seeks to clarify either of these aspects by providing a plain discussion of how the basic mechanisms of comparison as a cognitive device can be incorporated into clear and simple classroom aids and algorithms supporting goal-directed learning.     

Transient detailed balance and product form for reaction networks

This paper explores the boundary of the set of reaction networks that have an exact transient (truncated) multidimensional Poisson or product-form distribution for the number of particles of different types. Motivated by the birth–death process, we introduce the notions of transient detailed balance and delay functions, and use these notions to obtain the novel transient product-form distribution in a coagulation-fragmentation process for polymers with a tree-like structure from that of the pure coagulation process.     

How to Evaluate Government Performance while Building a Rule of Law Government in China*

Building a law-based government is a central element of the comprehensive framework for promoting the rule of law in China, while using evaluation to catalyze growth is in line with the incentive principle of management studies. Since China started to implement reform and opening up over thirty years ago, rule of law development and organizational evaluation have gone through several stages, each with different characteristics. Efforts to build a law-based government have met with success, but what the country now has is essentially still goal-oriented assessment. At present, this suffers from the lack of a clear goal orientation or definition of functions, an imperfect technical system and unsound motivation mechanisms, not to mention the practical problems of each government department going its own way, duplicating evaluations or being left rudderless. Drawing on a combination of value rationality and instrumental rationality and using government performance evaluation to promote the building of a law-based government not only conforms to the spirit of the rule of law and value rationality in government performance, but also strengthens the role of evaluation as an instrument for organizational management. Therefore, we need to create new evaluation theories, expand public participation, introducing diversified evaluating entities, improve technical systems, strengthen institutional buildup, and foster a performance-based culture. In addition, replacing goal-oriented assessment with performance evaluation will help the emergence of a new discipline—the performance evaluation of rule of law government, thus promoting multidisciplinary efforts to integrate and create new public administration theories in China.
