A questionnaire survey has been conducted on 396 parents of children with autism selected in Guangdong Province.The results are summarized as follow.(1)The level of post-traumatic growth of parents raising children with autism is above average.(2)The milder the symptoms of the children are,the higher the family income is,and the higher the level of post-traumatic growth of their parents is.Parents with a bachelor's degree or above have significantly higher levels of post-traumatic growth compared to those without such a degree.(3)The post-traumatic growth level of first married parents is significantly high-er than those of non-first married(remarried,divorced,widowed)parents.(4)There is a prominent positive correlation among so-cial support,quiet ego,psychological capital,and post-traumatic growth.Support by friends,optimism,and inclusive identity posi-tively predict post-traumatic growth with friends'support owing the greatest explanatory power.
With the advent of big data, massive amounts of high-dimensional data have been accumulated in many fields. The assimilation and processing of such high-dimensional data can be particularly challenging. Manifold learning offers a means for effectively dealing with this challenge. However, the results of applying manifold learning to supervised classification have remained unsatisfactory. The out-of-sample extension problem is a critical issue that must be properly solved in this regard. Genetic algorithms (GAs) have excellent global search capabilities. This paper proposes a generalized regression neural network (GRNN) optimized by a GA for the solution of the out-of-sample extension problem. The prediction performance of a GRNN mainly depends on the appropriateness of the chosen smoothing factor. The essence of the GA optimization is the determination of the optimal smoothing factor of the GRNN, the optimized form of which is subsequently used to forecast the low-dimensional embeddings of the test samples. A GA can be used to obtain a better smoothing factor in a larger search space, resulting in enhanced prediction performance. Experiments were performed to enable a detailed analysis of the important parameters that affect the performance of the proposed algorithm. The results confirmed the effectiveness of the algorithm.
睡虎地秦简《编年记》简二八,云:"(秦王政)廿一年,韩王死.昌平君居其处,有死□属."综合有关材料和研究,其中的阙字应释读作"为",而"昌平君居其处,有(又)死"当单独断句.由此可知,昌平君应死于秦王政二十一年.故而《史记·秦始皇本纪》所记秦王政二十三年,秦军虏荆王负刍和项燕立昌平君为荆王、反秦于淮南一事,是值得重新审视的.考《六国年表》《楚世家》《蒙恬列传》《王翦列传》等,这些篇目相关记载的史源均是《秦记》,一致记述了荆王负刍被虏于秦王政二十四年,且都没有昌平君反秦的身影.清人梁玉绳又指出《本纪》自身存在的一些史事发展矛盾.因此,有关项燕立昌平君反秦的记述虽载于《本纪》,但其可靠性应该被审慎对待.

自元戏曲兴起,各朝代戏曲家基于不同创作意图,将杨贵妃之死搬演上戏曲舞台,这些剧演各具特色:元白朴《梧桐雨》抒发贵妃之怨,元王伯成《天宝遗事诸宫调》表达贵妃之怒,明吴世美与屠隆肯定贵妃之情真,清洪昇《长生殿》赞赏贵妃之忠于情义.通过比较各剧书写马嵬坡杨贵妃之死的异同,可细细体会不同时代、不同经历的作者对杨贵妃的不同态度及对安史之乱这段历史的不同解读.
