建国以来民主党派政治资源的配置特点及合理性研究

民主党派的政治资源主要包括制度性资源、功能性资源、组织性资源、社会性资源和政策性资源,其配置格局与民主党派在我国政治体系以及多党合作制度中的政治定位密切相关.建国以来民主党派政治资源的配置状况,随着中国共产党对民主党派的性质、地位和作用的认识不断深化以及对政党关系定位日渐清晰、准确而日趋合理,其参政领域和选配职数不断扩大.     

A general approximation to quantiles

For many continuous distributions, a closed-form expression for their quantiles does not exist. Numerical approximations for their quantiles are developed on a distribution-by-distribution basis. This work develops a general approximation for quantiles using the Taylor expansion. Our method only requires that the distribution has a continuous probability density function and its derivatives can be derived to a certain order (usually 3 or 4). We demonstrate our unified approach by approximating the quantiles of the normal, exponential, and chi-square distributions. The approximation works well for these distributions.

Penalized empirical likelihood inference for sparse additive hazards regression with a diverging number of covariates

High-dimensional sparse modeling with censored survival data is of great practical importance, as exemplified by applications in high-throughput genomic data analysis. In this paper, we propose a class of regularization methods, integrating both the penalized empirical likelihood and pseudoscore approaches, for variable selection and estimation in sparse and high-dimensional additive hazards regression models. When the number of covariates grows with the sample size, we establish asymptotic properties of the resulting estimator and the oracle property of the proposed method. It is shown that the proposed estimator is more efficient than that obtained from the non-concave penalized likelihood approach in the literature. Based on a penalized empirical likelihood ratio statistic, we further develop a nonparametric likelihood approach for testing the linear hypothesis of regression coefficients and constructing confidence regions consequently. Simulation studies are carried out to evaluate the performance of the proposed methodology and also two real data sets are analyzed.

Bayesian analysis of a multiple-recapture model

In the Bayesian analysis of a multiple-recapture census, different diffuse prior distributions can lead to markedly different inferences about the population size N. Through consideration of the Fisher information matrix it is shown that the number of captures in each sample typically provides little information about N. This suggests that if there is no prior information about capture probabilities, then knowledge of just the sample sizes and not the number of recaptures should leave the distribution of Nunchanged. A prior model that has this property is identified and the posterior distribution is examined. In particular, asymptotic estimates of the posterior mean and variance are derived. Differences between Bayesian and classical point and interval estimators are illustrated through examples.

联网通用与我国银行卡组织的反垄断

作为新兴产业的我国银行卡业发展缓慢,并严重滞后,联网通用问题尤为突出.我国银行业的高度垄断性是阻碍联网通用发展,也是延缓整个银行卡产业规模扩大的重要原因.中国银联作为人民币转接市场唯一的服务机构,其不断受到来自商户和商业银行的垄断质疑,其实施的限制竞争行为也是阻碍联网通用不能有效实现的重要原因.随着银行卡产业的发展,我国银行卡产业亟需反垄断规制.
