现代汉语形容词的词缀与附加式构词法

本文运用现代语言学形态学理论,从形容词的词缀与词根的区别、词缀与助词的区别角度切入,界定了现代汉语形容词词缀概念的内涵和外延,分析了现代汉语形容词的构词词缀和构形词缀这两种词缀类型;重点探讨了附加式形容词的词缀、构词方式及语法功能,详细分析了现代汉语形容词的"词缀+词根"、"词根+词缀+词根"、"词根+词根+词缀"和"词根+词缀"四种组合方式及其具体类型,进而从一个侧面揭示了现代汉语形容词的形态特征.     

Conditional Generalized Liouville Distributions on the Simplex

Liouville and generalized Liouville distributions on the simplex have been proposed for modeling compositional data and have been shown to be free from the extreme independence structure that characterizes the Dirichlet class. In this article, generalized Liouville distributions are shown to be rich enough to distinguish some lesser modes of independence as well. Unfortunately, it is noted that the applicability of the Liouville family will be limited, owing to the lack of invariance with respect to the chosen fill-up value. As an alternative, a new family of simplex distributions is proposed, one that admits invariance with respect to choice of fill-up value, as well as the ability to differentiate among many forms of independence.

可持续发展的产业分类理论——立体产业分类理论

本世纪 60年代以来 ,自然资源产业、环保产业、高新技术产业 (包括信息产业 )等新兴产业迅速发展 ,其对可持续发展的促进作用 ,已经为各国经济发展的实践所证明 ,也给产业经济研究提出了现实的问题。传统产业分类理论没有对新兴产业的内涵、归属及其在产业结构中的地位等加以揭示 ,使得建立在传统产业分类理论基础上的产业结构演进理论解释现象、指导经济实践的能力减弱。作者在深入分析传统产业分类理论的局限的基础上 ,提出可持续发展的产业分类理论     

Welfare generosity, pregnancies and abortions among unmarried AFDC recipients

Even before the 1996 overhaul of the U.S. welfare system, a number of states had ended the practice of paying extra benefits to families who have additional children while receiving welfare. Proponents believe that this reform can reduce births to recipients, however many worry that it may encourage women to obtain abortions. Using a sample of unmarried AFDC recipients from the NLSY, we estimate a bivariate probit model of pregnancy and, conditional on becoming pregnant, the probability of abortion. Our results lend some support for the proposition that reducing incremental AFDC benefits will decrease pregnancies without increasing abortions. Received: 16 April 1998/Accepted: 11 March 1999     

中国干群矛盾的类别、发展趋势及缓解机制研究

干群矛盾是中国社会矛盾中最特别、最具有爆炸性的类型,全面解析干群矛盾是社会矛盾预警及治理的重要环节.文章从性质、主体、地域、表现形式、发展阶段、激烈程度等方面对干群矛盾进行分类,把握其发展的现状,概括出具有普遍性、局部激化、振荡调整、危害性大等特征,指出主要诱因包括政治利益冲突、经济利益冲突和情感利益冲突.预测其发展趋势将更为激烈.而且成为其他社会矛盾演化成大规模冲突的催化剂.提出了"一个中心三个层面"、预警机制、综合控制机制等缓解、化解干群矛盾的机制.

A comparison of classification models to identify the Fragile X Syndrome

The main models of machine learning are briefly reviewed and considered for building a classifier to identify the Fragile X Syndrome (FXS). We have analyzed 172 patients potentially affected by FXS in Andalusia (Spain) and, by means of a DNA test, each member of the data set is known to belong to one of two classes: affected, not affected. The whole predictor set, formed by 40 variables, and a reduced set with only nine predictors significantly associated with the response are considered. Four alternative base classification models have been investigated: logistic regression, classification trees, multilayer perceptron and support vector machines. For both predictor sets, the best accuracy, considering both the mean and the standard deviation of the test error rate, is achieved by the support vector machines, confirming the increasing importance of this learning algorithm. Three ensemble methods - bagging, random forests and boosting - were also considered, amongst which the bagged versions of support vector machines stand out, especially when they are constructed with the reduced set of predictor variables. The analysis of the sensitivity, the specificity and the area under the ROC curve agrees with the main conclusions extracted from the accuracy results. All of these models can be fitted by free R programs.
