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.

事实、价值与道德选择

在道德选择的理论与实践中,必然遇到事实与价值的关系问题。事实与价值统一于"实际活动着的人"自身。正确的道德选择应建立在价值判断与事实判断统一的基础上,忽视了事实判断作用的道德选择,必然会最终导致对道德价值自身的否定。从人格完善过程的角度来分析,道德选择又是德行与智慧的统一。     

Bayesian t-tests for correlations and partial correlations

In this paper, we develop Bayes factor based testing procedures for the presence of a correlation or a partial correlation. The proposed Bayesian tests are obtained by restricting the class of the alternative hypotheses to maximize the probability of rejecting the null hypothesis when the Bayes factor is larger than a specified threshold. It turns out that they depend simply on the frequentist t-statistics with the associated critical values and can thus be easily calculated by using a spreadsheet in Excel and in fact by just adding one more step after one has performed the frequentist correlation tests. In addition, they are able to yield an identical decision with the frequentist paradigm, provided that the evidence threshold of the Bayesian tests is determined by the significance level of the frequentist paradigm. We illustrate the performance of the proposed procedures through simulated and real-data examples.
