公共产品类型、绩效与政府满意度差异

利用北京大学中国国情研究中心2010年公共产品与政府服务调查数据,探究了公共产品类型和绩效对中央和地方政府满意度的不同影响。根据民众对政府公共产品提供责任的期望,将公共产品分为完全政府型、政府主导型和个体主导型3类。回归结果显示,公共产品提供绩效对中央政府满意度影响较小,对地方政府满意度影响较大。其中,中央政府受政府主导型公共产品影响最为显著,地方政府受个体主导型公共产品影响较大。     

Analysis of incomplete data in the presence of dependent competing risks from Marshall–Olkin bivariate Weibull distribution under progressive hybrid censoring

This article considers the statistical analysis of dependent competing risks model with incomplete data under Type-I progressive hybrid censored condition using a Marshall–Olkin bivariate Weibull distribution. Based on the expectation maximum algorithm, maximum likelihood estimators for the unknown parameters are obtained, and the missing information principle is used to obtain the observed information matrix. As the maximum likelihood approach may fail when the available information is insufficient, Bayesian approach incorporated with auxiliary variables is developed for estimating the parameters of the model, and Monte Carlo method is employed to construct the highest posterior density credible intervals. The proposed method is illustrated through a numerical example under different progressive censoring schemes and masking probabilities. Finally, a real data set is analyzed for illustrative purposes.     

What Do Interpolated Nonparametric Confidence Intervals for Population Quantiles Guarantee?

The interval between two prespecified order statistics of a sample provides a distribution-free confidence interval for a population quantile. However, due to discreteness, only a small set of exact coverage probabilities is available. Interpolated confidence intervals are designed to expand the set of available coverage probabilities. However, we show here that the infimum of the coverage probability for an interpolated confidence interval is either the coverage probability for the inner interval or the coverage probability obtained by removing the more likely of the two extreme subintervals from the outer interval. Thus, without additional assumptions, interpolated intervals do not expand the set of available guaranteed coverage probabilities.     

Bernstein type inequalities for self-normalized martingales with applications

For self-normalized martingales with conditionally symmetric differences, de la Peña [A general class of exponential inequalities for martingales and ratios. Ann Probab. 1999;27(1):537–564] established the Gaussian type exponential inequalities. Bercu and Touati [Exponential inequalities for self-normalized martingales with applications. Ann Appl Probab. 2008;18:1848–1869] extended de la Peña's inequalities to martingales with differences heavy on left. In this paper, we establish Bernstein type exponential inequalities for self-normalized martingales with differences bounded from below. Moreover, applications to t-statistics and autoregressive processes are discussed.     

就明代进士祖上的生员身份与何炳棣再商榷——以天一阁藏《明代进士登科录》为中心

本文通过对天一阁藏《明代进士登科录》的爬梳,确认明代进士祖上三代生员出身少的现象乃史籍缺载所致。事实上,明代生员概率接近常态;何炳棣采集的史料若特指生员而言,其来源本身就有局限性,由此统计的数据不宜当作明代进士社会流动率高的一个依据。天一阁藏《明代进士登科录》在讨论明代B类进士时,具有不可替代的作用。明代进士祖上三代生员身份的有限记载,主要来自民间的《进士同年录》而非官方的《进士登科录》。生员身份是否有资格作为进士家状的基本内容之一,必载于或应载于《明代进士登科录》?若是,又始于何年?作者求教于方家。     

宅基地使用权流转的路径

宅基地使用权禁止流转制度使得实践中规避法律的行为十分普遍,形成错综复杂的农村宅基地使用权和住房交易的"隐形市场",为土地使用权的正常流转埋下了隐患,严重影响了社会的稳定.宅基地使用权流转势在必行."房随地走、地随房走"原则已成为宅基地使用权流转的障碍.如何在现有制度框架下通过循序渐进的改革方式,解决宅基地使用权的流转应是研究的方向.通过"两步走"的完善方式,先建立宅基地有期限、有偿使用制度及完善的农村宅基地使用权登记制度,最终实现集体土地的国有化,纳入统一的土地流转方式.由此既解决了现实存在的宅基地使用权流转问题,又从根本上解决了宅基地属性问题,因此,是经济成本、社会成本较低的合理解决方式.     

论广州城市管理中的公众参与

为确保公众参与城市管理,实现城市管理的＂以人为本＂,建设公众参与城市管理平台,使公众自下而上地参与和政府自上而下地管理形成合力,更好地为提高城市综合竞争力、提升城市人居环境质量服务,广州市进行了公众参与城市管理的有益的尝试。针对广州公众参与城市管理提出相应对策的多种思路,提出了促使广州公众参与、上台阶的三大对策。
