农地产权结构变迁视域下土地增值收益的公平分享

农地产权结构是搭建土地增值收益分配与宪法秩序有效链接的重要桥梁.从农地产权结构变迁的视角看,我国传统土地增值收益的国有化机制实际在很大程度上符合1982年宪法所确立的社会主义地租国有原则及地利共享秩序.然而,由于宪法土地条款一开始就被注入了地利分配具有倾向性的思想基因,长此以往便忽视了农民作为整体分享土地增值收益的"另一半宪法秩序".新型城镇化背景下,国家进行了"同地同权"、赋权于"民"的农村土地管理制度改革,其实质是宪法秩序的延续而非替代,我国土地增值收益分配的主要机制仍是征地补偿制度.要实现我国土地增值收益的公平分享,必须回到社会主义"国家—集体"一元论的完整地利共享秩序中来,并遵循实质平等的要求,通过以"人的城镇化"为目标对区片综合地价进行限定、采取倾向于农村及农业发展的"土地财政"政策、打破城乡户籍二元制实现城乡一体化发展等方案,推动农民全过程参与、共享土地利益.

Abstract

Characterizing relations via Rényi entropy of m-generalized order statistics are considered along with examples and related stochastic orderings. Previous results for common order statistics are included.     

Design selection for strong orthogonal arrays

Strong orthogonal arrays (SOAs) were recently introduced and studied as a class of space‐filling designs for computer experiments. An important problem that has not been addressed in the literature is that of design selection for such arrays. In this article, we conduct a systematic investigation into this problem, and we focus on the most useful SOA(n,m,4,2 + )s and SOA(n,m,4,2)s. This article first addresses the problem of design selection for SOAs of strength 2+ by examining their three‐dimensional projections. Both theoretical and computational results are presented. When SOAs of strength 2+ do not exist, we formulate a general framework for the selection of SOAs of strength 2 by looking at their two‐dimensional projections. The approach is fruitful, as it is applicable when SOAs of strength 2+ do not exist and it gives rise to them when they do.

The quantile-based flattened logistic distribution: Some properties and applications

In this paper, the quantile-based flattened logistic distribution has been studied. Some classical and quantile-based properties of the distribution have been obtained. Closed form expressions of L-moments, L-moment ratios and expectation of order statistics of the distribution have been obtained. A quantile-based analysis concerning the method of matching L-moments estimation is employed to estimate the parameters of the proposed model. We further derive the asymptotic variance–covariance matrix of the matching L-Moments estimators of the proposed model. Finally, we apply the proposed model to simulated as well as two real life datasets and compare the fit with the logistic distribution.     

Computing maximum likelihood estimates from type II doubly censored exponential data

It is well-known that, under Type II double censoring, the maximum likelihood (ML) estimators of the location and scale parameters, θ and δ, of a twoparameter exponential distribution are linear functions of the order statistics. In contrast, when θ is known, theML estimator of δ does not admit a closed form expression. It is shown, however, that theML estimator of the scale parameter exists and is unique. Moreover, it has good large-sample properties. In addition, sharp lower and upper bounds for this estimator are provided, which can serve as starting points for iterative interpolation methods such as regula falsi. Explicit expressions for the expected Fisher information and Cramér-Rao lower bound are also derived. In the Bayesian context, assuming an inverted gamma prior on δ, the uniqueness, boundedness and asymptotics of the highest posterior density estimator of δ can be deduced in a similar way. Finally, an illustrative example is included.     

公共政策的社会观基础

本文从一个新的视角──社会现的视角──审视了公共政策。因为在过去的有关公共政策的定义中，我们无法看出各个政策的重大区别，而事实上它们在是否符合人性的需求，充分考虑民意的基础并有效促进了人民的自由与福利等方面是有着重大区别的。本文将公共政策界定为是一定的权利中心在众多备选的计划、规划或可行之行动方案中作出选择并采取行动的这样一个过程。由此对选择的社会观基础进行考察，社会观影响到了人们对待集体行动的态度，进而又影响到社会秩序观。而持有不同的社会秩序观的人对公共政策有着根本不同的看法，最终得出好的公共政策的基本的制度安排。

鲍靓符箓道术考论

两晋之际,琅邪人鲍靓出任南海太守,在岭南传播符箓道术,成为迄今有史可考最早进入岭南的道教符箓派人物。鲍靓的符箓术及其符箓派,无论对岭南道教乃至中国道教的发展,抑或对岭南人的思想意识、民风习俗和宗教信仰均产生了深远影响。     

唐五代敦煌的宴饮坐向和座次研究

朱德与中共第一代领导集体的形成

朱德进入中共中央第一代领导集体 ,凭藉的是他的卓越的军事贡献和丰富的政治经验。从“红军之父”到“中国军人的伟大导师” ,从“人民的救星”到“党的领袖” ,既表明了他对党和人民事业的无限忠诚 ,也蕴含着党和人民给予他的极大光荣 ,反映了他追求进步 ,服从真理 ,实事求是 ,不断创新的卓越品质。第一代领导集体形成的标志时期是党的七大。朱德在第一代领导集体中的地位非常重要 ,他实际上起了一个稳定的中和的作用 ;从194 5年到 195 6年 ,朱德在中共中央和中央军委的职务、地位和威望仅次于毛泽东。
