摘要： 合同的法定形式要求对合同的效力和合同的救济可能产生不同的影响 ,而我国合同法对于合同法定形式的规定还过于原则 ,不具有可操作性。本文通过对我国合同法有关规定进行比较研究 ,最后提出相应的完善建设。

摘要： 从理论界对合同诈骗罪犯罪故意的形式是否包括间接故意的争论分析 ,只能得出本罪犯罪故意是直接故意的结论 ;从刑法理论应适应经济发展的需要分析 ,应将间接故意也作为本罪犯罪故意的一种形式。

摘要： 我国《合同法》第 1 2 2条规定在违约责任与侵权责任发生竞合的情况下 ,受害人一方可选择提起违约之诉或侵权之诉。笔者认为此项规定是源于过去的理论 ,与其他法律不协调 ,脱离我国实际。在发生违约责任与侵权责任竞合的情况下 。

摘要： In computer-aided diagnosis (CAD), a frequently used approach for distinguishing normal and abnormal cases is first to extract potentially useful features for the classification task. Effective features are then selected from this entire pool of available features. Finally, a classifier is designed using the selected features. In this study, we investigated the effect of finite sample size on classification accuracy when classifier design involves stepwise feature selection in linear discriminant analysis, which is the most commonly used feature selection algorithm for linear classifiers. The feature selection and the classifier coefficient estimation steps were considered to be cascading stages in the classifier design process. We compared the performance of the classifier when feature selection was performed on the design samples alone and on the entire set of available samples, which consisted of design and test samples. The area A(z) under the receiver operating characteristic curve was used as our performance measure. After linear classifier coefficient estimation using the design samples, we studied the hold-out and resubstitution performance estimates. The two classes were assumed to have multidimensional Gaussian distributions, with a large number of features available for feature selection. We investigated the dependence of feature selection performance on the covariance matrices and means for the two classes, and examined the effects of sample size, number of available features, and parameters of stepwise feature selection on classifier bias. Our results indicated that the resubstitution estimate was always optimistically biased, except in cases where the parameters of stepwise feature selection were chosen such that too few features were selected by the stepwise procedure. When feature selection was performed using only the design samples, the hold-out estimate was always pessimistically biased. When feature selection was performed using the entire finite
