Functional Partial Linear Single‐index Model

This paper deals with the problem of predicting the real‐valued response variable using explanatory variables containing both multivariate random variable and random curve. The proposed functional partial linear single‐index model treats the multivariate random variable as linear part and the random curve as functional single‐index part, respectively. To estimate the non‐parametric link function, the functional single‐index and the parameters in the linear part, a two‐stage estimation procedure is proposed. Compared with existing semi‐parametric methods, the proposed approach requires no initial estimation and iteration. Asymptotical properties are established for both the parameters in the linear part and the functional single‐index. The convergence rate for the non‐parametric link function is also given. In addition, asymptotical normality of the error variance is obtained that facilitates the construction of confidence region and hypothesis testing for the unknown parameter. Numerical experiments including simulation studies and a real‐data analysis are conducted to evaluate the empirical performance of the proposed method.     

后现代语境下我国马克思主义社会学批评境遇的思考

马克思主义的社会学批评在上个世纪中国的文学舞台上经历了两次的浮沉,但是社会学批评的这两次式微却存在着本质的不同。本文通过分析后现代语境对马克思主义"社会学批评"在创作主体、批评主体、真理、理性、"宏大的历史叙事"、文学经典、唯物史观、读者身份等方面的颠覆和消解,试图凸现马克思主义"社会学批评"在第二次式微过程中面临的理论挑战,提出重新定位和理论发展的问题。     

特征AHP在高校教师教学质量评定中的应用

本文针对高校教师教学质量的评定提出了一种特征层次分析法。首先通过分析教学质量的影响因素,建立三层层次分析模型。在其基础上引入特征法,选取特征群并确定特征群中个体的权重,利用反算法根据组合权重及方案层权重,求取准则层评定指标权重,避免了不同质指标间对比的不确定性,摒除了专家直接给出评定指标对比矩阵的主观性,减少了对教师评定过程的不一致性和不完备性。     

谈热奈特的叙事时序理论

叙事时序理论是热奈特在叙事时间研究中取得的重要成果.热奈特认为时间倒错包含追叙和预叙两种形式,但是笔者认为这种概括不全面,还应有第三种情况分叙.国内学者大多将"追叙"(flashback)译为"倒叙",分析了两者的差异.     

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.

一座新型的开启桥——梅江南开启桥

一、概述 开启桥是一种兼顾道路交通和水路通航的特殊桥梁,建造开启桥需要机械、电气、钢结构、土木工程等技术的综合应用.现代的开启桥按开启方式可分为三大类:平转式、立转式和垂直提升式.国际上有很多的开启桥不仅解决了城区内河流和港口桥梁的通航问题,而且成为了当地一种特色建筑,为城市景观增添光彩.建造开启桥最多的国家是美国,上个世纪70年代,美国已建有不同形式的开启桥2200余座,并制定了公路开启桥规范.
