刑法溯及力原则立法上的缺失——兼论中间时法的生存之理

<中华人民共和国刑法>对溯及力问题作了从旧兼从轻的原则性规定,这是我国刑法向科学化、民主化方向发展的重要表现,然而刑法在其动态运行中又产生了中间时法的问题.本文通过对中间时法的产生及其机理的分析,并结合中间时法在我国实践中的作用,探讨了刑法对中间时法效力亟待完善的问题.     

Fuzzy K-means clustering models for triangular fuzzy time trajectories

We focus our attention on the classification of fuzzy time trajectories with triangular membership function, described by a given set of individuals. To this purpose, we adopt a fullyinformational approach, explicitly recognizing the informational nature shared by the ingredients of the classification procedure: the observed data (Empirical Information) and the classification model (Theoretical Information). In particular, by supposing that the informational paradigm has a fuzzy nature, we suggest three fuzzy clustering models allowing the classification of the triangular fuzzy time trajectories, based on the analysis of the cross sectional and/or longitudinal characteristics of their components (centers and spreads). Two applicative examples are illustrated.     

抗战前重庆近代报业情况研究 --以《商务日报》为例

20世纪初,随着资产阶级革命运动的兴起,国内报刊活动空前活跃.重庆近代报业也伴随时代风潮产生、发展起来.作为新兴媒介,同这一特殊历史时期的国家一样,经历了种种风云变幻、艰难屈辱,却最终顽强坚韧地壮大起来.以重庆当时土生土长、在本地刊行时间最长的<商务日报>为样本,分析研究近代重庆地方报业的发展情况及特点.     

论风险投资的退出机制

风险资本的退出是风险投资运作的最后一个环节,风险投资的成败在很大程度上取决于风险投资家能否成功地退出投资。文章在参考国内外有关文献的基础上,对风险投资退出方式、退出时机、退出程度,以及退出决策进行较为系统的评述,以期促进我国风险投资业的发展。     

Residual analysis for spatial point processes (with discussion)

Summary.  We define residuals for point process models fitted to spatial point pattern data, and we propose diagnostic plots based on them. The residuals apply to any point process model that has a conditional intensity; the model may exhibit spatial heterogeneity, interpoint interaction and dependence on spatial covariates. Some existing ad hoc methods for model checking (quadrat counts, scan statistic, kernel smoothed intensity and Berman's diagnostic) are recovered as special cases. Diagnostic tools are developed systematically, by using an analogy between our spatial residuals and the usual residuals for (non-spatial) generalized linear models. The conditional intensity λ plays the role of the mean response. This makes it possible to adapt existing knowledge about model validation for generalized linear models to the spatial point process context, giving recommendations for diagnostic plots. A plot of smoothed residuals against spatial location, or against a spatial covariate, is effective in diagnosing spatial trend or co-variate effects. Q – Q -plots of the residuals are effective in diagnosing interpoint interaction.     

连续时延神经网络的Hopf分岔现象研究

讨论了带连续时延神经网络的Hopf分岔现象。对于强核和弱核的情况,利用平均时延作为分岔参数,证明了模型经历了Hopf分岔过程。在带弱核的神经网络模型中,得到了分岔周期解稳定性准则。给出了一些数值例子,通过计算机仿真验证了所得结论的正确性。
