民国初期广西三关对外贸易商品结构分析(1912～1931)

近代梧州、南宁、龙州三海关是广西最重要的对外贸易口岸,在我国近代对外贸易中占有一席之地。广西对外贸易出口商品基本是初加工或是未经过加工的农副产品,以技术含量低,技术附加值低的劳动密集型产品占主导地位。出口商品以农民自发的个体小规模经营为主,成规模经营极为少见。进口商品以日常生活所需的生活资料为主,其商品结构与我国的进口商品结构相似。随着对外贸易的发展,大宗进口商品的数量、价格都在不断增加。本地土产的产品在市场竞争中最终不敌洋货,洋货市场需求与日俱增,洋货的价格也在不断上扬,大量洋货的涌入,不仅加速了自然经济的崩溃,而且加重了百姓生活的经济负担。     

"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.     

Opportunities for woman-initiated HIV prevention methods among female sex workers in southern China

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.

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.
