市场纠纷与政府介入——一个风险转化的解释框架

本文讨论市场治理中的政府介入问题,即宣称为规则制定者或市场监管者的地方政府为何会深度介入市场主体之间的交易纠纷。结合社会学和经济学的制度分析,本文建构了一个风险转化的理论框架,并用其解读温州民间借贷服务中心的一起借贷纠纷案例。研究表明,政府介入交易纠纷的过程,涉及经济风险向政治风险转化以及政府对风险转化的回应两个方面;法律的完备性、政府与市场主体的关联性、政府之于社会的可退出性,是影响风险转化的三个结构性因素;面对风险转化,政府感知到的潜在政治风险强度越大,越容易介入交易纠纷。本文为市场转型中的政府角色研究和市场制度的社会建构研究提供了新的分析路径。     

Nonparametric Bayesian inference for multivariate density functions using Feller priors

Multivariate density estimation plays an important role in investigating the mechanism of high-dimensional data. This article describes a nonparametric Bayesian approach to the estimation of multivariate densities. A general procedure is proposed for constructing Feller priors for multivariate densities and their theoretical properties as nonparametric priors are established. A blocked Gibbs sampling algorithm is devised to sample from the posterior of the multivariate density. A simulation study is conducted to evaluate the performance of the procedure.     

论伊德的科学价值观

伊德"非中性"的科学价值观揭示的是科学的本体论意义上的价值维度,而传统的科学价值观是事实与价值分离的"中性论"的价值观。伊德认为,传统的科学的价值观没有深入到本体论、生成论意义层次,是缺乏深度的知识论意义上的价值观。停留于此基础上的价值观,难免导致科学的"乌托邦"或"敌托邦"。     

Modeling the Adenoma and Serrated Pathway to Colorectal CAncer (ASCCA)

Several colorectal cancer (CRC) screening models have been developed describing the progression of adenomas to CRC. Currently, there is increasing evidence that serrated lesions can also develop into CRC. It is not clear whether screening tests have the same test characteristics for serrated lesions as for adenomas, but lower sensitivities have been suggested. Models that ignore this type of colorectal lesions may provide overly optimistic predictions of the screen‐induced reduction in CRC incidence. To address this issue, we have developed the Adenoma and Serrated pathway to Colorectal CAncer (ASCCA) model that includes the adenoma‐carcinoma pathway and the serrated pathway to CRC as well as characteristics of colorectal lesions. The model structure and the calibration procedure are described in detail. Calibration resulted in 19 parameter sets for the adenoma‐carcinoma pathway and 13 for the serrated pathway that match the age‐ and sex‐specific adenoma and serrated lesion prevalence in the COlonoscopy versus COlonography Screening (COCOS) trial, Dutch CRC incidence and mortality rates, and a number of other intermediate outcomes concerning characteristics of colorectal lesions. As an example, we simulated outcomes for a biennial fecal immunochemical test screening program and a hypothetical one‐time colonoscopy screening program. Inclusion of the serrated pathway influenced the predicted effectiveness of screening when serrated lesions are associated with lower screening test sensitivity or when they are not removed. To our knowledge, this is the first model that explicitly includes the serrated pathway and characteristics of colorectal lesions. It is suitable for the evaluation of the (cost)effectiveness of potential screening strategies for CRC.

民间传说与文献记载的关联：以巫山神女传说为例

现有文献中有关巫山神女的记载较多,三峡地区也有不少关于神女传说的版本,只是其与文献记载的神女故事情节相差甚远。民众在创作民间传说时,会根据具体的自然环境、社会伦理道德要求、自身的价值观、主流社会的需要以及文化传播等多种因素,完成传说情节的塑造。     

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.
