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.     

Rényi entropy of m-generalized order statistics

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.     

诗与士人的精神世界:试以王维的生命史和编年诗为例的社会学探索

费孝通先生晚年倡导面向“精神世界”的社会学研究，不仅强调了社会学的人文性格，而且指明了回溯和整理传统思想资源以理解人心的意义。古代士人在仕隐之间的进退趋避是精神世界研究的重要课题，盛唐诗人王维可作为重要个案。本文运用“知人论世”的方法，以王维的生命史、编年诗及他与其他诗人的交往为线索，考察其如何在仕隐之间调适精神世界的矛盾冲突。王维通过人际和诗文往来形成的社会交游空间、自然山水空间和灵性佛理空间，构成一个融和自然与人文的“人生圜局”，以寻求精神世界在“入世有为”和“消极退避”之间的平衡，而其精神苦痛也可以从这个圜局的层级变动或缺失中探寻根源。本文认为，把握世风民情、生命史的再现以及理解和体会的功夫，是研究士人精神世界的重要门径。     

从抽象王国到现实世界--读《费尔巴哈论》

恩格斯在《费尔巴哈论》中从历史观的高度揭示马克思主义哲学同它的直接理论来源之间的内在联系 ,这一联系的实质是从抽象王国走向现实世界。因此 ,从抽象王国到现实世界是《费尔巴哈论》一书的真正主题。     

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.     

话题转换的顺应性研究

根据顺应理论,使用语言的过程是一个进行选择的过程,语言使用者不仅选择语言形式,同时还选择使用策略。话题转换现象是对社会规约和心理世界的一种顺应。话题转换不当,会产生负面影响,妨碍交际的进行。     

论马克思主义哲学的生命力

马克思主义哲学在新的历史条件下面临着新的挑战 :诞生于 19世纪的马克思主义哲学是否还适用于今天 ?2 0世纪世界范围内的科技革命的兴起是否造成了它的过时 ?社会主义运动在实践上的挫折应否由马克思主义哲学负责 ?其实 ,马克思主义哲学是一个具有自我超越能力的开放体系 ,它仍然是我们时代精神的精华 ,社会主义历史实践的失误恰恰是由于违背了马克思主义哲学的基本原则造成的。对马克思主义哲学进行创造性的阐释 ,使它保持一种开放的对话姿态 ,并避免其沦为狭隘利益的工具 ,乃是保持它的生命力的根本途径。     

马克思的社会形态理论辨正

马克思的社会形态理论是五形态理论 ,该理论在马克思那里有充分的文本根据 ,马克思始终坚持了该理论。理解五形态理论的视角至关重要 ,须从“世界历史”的视角去理解它。马克思的五形态理论不是社会发展的单线论 ,而是既坚持社会发展规律的普遍性 ,又承认单个国家发展道路特殊性的辨证决定论。马克思不仅精辟地分析了在“世界历史”的大环境下个别国家超越式发展的深层原因 ,而且还提出了社会发展的三种基本的模式
