"百苗图"源流考略--以《黔苗图说》为范本

“百苗图”是历史背景较为复杂的一种反映贵州古代少数民族的地方文献,其版本众多。据考,它们是源自清人陈浩著的《八十二种苗图并说》。关于其母本的产生历史,学术界纷争不一。《黔苗图说》是贵州省博物馆收藏的一部较为典型的百苗图册页。本文以它为例,试对“百苗图”的源流做一些考证。并认为其母本并非某一时代实地调查的第一手资料,而主要是利用许多地方文献的相关材料编纂成册。     

Testing Serial Correlation in Partially Linear Additive Errors-in-variables Models

This article considers testing serial correlation in partially linear additive errors-in-variables model. Based on the empirical likelihood based approach, a test statistic was proposed, and it was shown to follow asymptotically a chi-square distribution under the null hypothesis of no serial correlation. Finally, some simulation studies are conducted to illustrate the performance of the proposed method.     

Validation of Nonparametric Two-sample Bootstrap in ROC Analysis on Large Datasets

The nonparametric two-sample bootstrap is applied to computing uncertainties of measures in receiver operating characteristic (ROC) analysis on large datasets in areas such as biometrics, speaker recognition, etc. when the analytical method cannot be used. Its validation was studied by computing the standard errors of the area under ROC curve using the well-established analytical Mann–Whitney statistic method and also using the bootstrap. The analytical result is unique. The bootstrap results are expressed as a probability distribution due to its stochastic nature. The comparisons were carried out using relative errors and hypothesis testing. These match very well. This validation provides a sound foundation for such computations.     

Bayesian variable selection approach to a Bernstein polynomial regression model with stochastic constraints

This paper provides a Bayesian estimation procedure for monotone regression models incorporating the monotone trend constraint subject to uncertainty. For monotone regression modeling with stochastic restrictions, we propose a Bayesian Bernstein polynomial regression model using two-stage hierarchical prior distributions based on a family of rectangle-screened multivariate Gaussian distributions extended from the work of Gurtis and Ghosh [7 S.M. Curtis and S.K. Ghosh, A variable selection approach to monotonic regression with Bernstein polynomials, J. Appl. Stat. 38 (2011), pp. 961–976. doi: 10.1080/02664761003692423[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]]. This approach reflects the uncertainty about the prior constraint, and thus proposes a regression model subject to monotone restriction with uncertainty. Based on the proposed model, we derive the posterior distributions for unknown parameters and present numerical schemes to generate posterior samples. We show the empirical performance of the proposed model based on synthetic data and real data applications and compare the performance to the Bernstein polynomial regression model of Curtis and Ghosh [7 S.M. Curtis and S.K. Ghosh, A variable selection approach to monotonic regression with Bernstein polynomials, J. Appl. Stat. 38 (2011), pp. 961–976. doi: 10.1080/02664761003692423[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]] for the shape restriction with certainty. We illustrate the effectiveness of our proposed method that incorporates the uncertainty of the monotone trend and automatically adapts the regression function to the monotonicity, through empirical analysis with synthetic data and real data applications.     

Did State Children’s Health Insurance Program Affect Married Women’s Labor Supply?

While the relationships between health insurance and the labor supply of women have been explored in the literature, little is known about the effects of offering public health insurance on the labor supply decisions of married women. This paper examines how the enactment of the State Children’s Health Insurance Program (SCHIP) affected the labor supply decisions of married women. Our empirical analysis showed that certain groups of married women reduced their number of hours worked upon SCHIP implementation. The results imply it is possible that some wives decreased their labor supply in order to make their children eligible for public health insurance.

智力资源对物质资源的部分替代与我国集约经济的发展

任何生产活动都需要一定的资源,投入资源之间会形成一定的比例。在很多情况下,投入资源之间的比例是可变的,即资源之间存在着一定程度的替代关系。理想的状况是,是根据各种资源的稀缺程度、效率等因素对其进行合理组合。根据我国经济发展的状况以及资源秉赋,我国应增加智力资源的投入、减少物质资源的消耗,即实现智力资源对物质资源的部分替代,这种替代具有很强的必要性、可能性和现实性。     

试论洪大容的实学思想

朝鲜李朝后期的“北学派”肇始于洪大容,他的实学思想具有开创意义,尤其在宇宙自然观方面,为“北学派”实学奠定了宇宙自然观、世界观的基础。他的“实心实学”也受到当代韩、日两国实学界的关注。在“北学派”实学家中,洪大容最先到了中国,考察了京、热、冀、辽的经济、政治、文化、社会民情、风土文物,最早提出了北学中国的主张,因此,具有重要的文化史意义和开风气的作用。
