A nonparametric allocation scheme for classification based on transvariation probabilities

In this paper, a nonparametric discriminant analysis procedure that is less sensitive than traditional procedures to deviations from the usual assumptions is proposed. The procedure uses the projection pursuit methodology where the projection index is the two-group transvariation probability. Montanari [A. Montanari, Linear discriminant analysis and transvariation, J. Classification 21 (2004), pp. 71–88] proposed and used this projection index to measure group separation but allocated the new observation using distances. Our procedure employs a method of allocation based on group–group transvariation probability to classify the new observation. A simulation study shows that the procedure proposed in this paper provides lower misclassification error rates than classical procedures like linear discriminant analysis and quadratic discriminant analysis and recent procedures like maximum depth and Montanari's transvariation-based classifiers, when the underlying distributions are skewed and/or the prior probabilities are unequal.     

思政课新课程方案下教师队伍建设研究

高校思政课新课程方案对教师队伍的整体结构和整体素质提出了新的更高的要求。要优化教师队伍结构和素质,必须严格按照课程教学需要考核和接收新教师,选派现有教师参加培训和进修,鼓励中青年教师攻读高学历(学位),定期组织教师开展内部培训和岗位练兵,广泛开展校际经验交流,促进教师在校际间的流动,并将教师队伍建设同学科建设、课程建设、教材建设紧密结合起来。     

Detection of concordance for extreme ranks

When analysing ranking data from one or more groups of judges one may wish to allow for the possibility that the judges have paid more attention to the allocation of the extreme ranks, rather than to the intermediate ranks. In some cases they may have only worried about assigning the top ranks (1 and 2, say) while randomly allocating the remaining ones.

In another context, the analystmay wish to only take account of the agreement among judges with respect to extreme ranks (top or bottom, or both),

In such situations an analysis of concordance within, and between groups, if appropriate, should be able to deal with extreme ranks specifically. We propose a data analyticapproach, related to an analysis of diversity,which actyally permits an analysis of concordance for each rank separately.     

On some alternative procedures using ranks for the analysis of experimental designs

The analysis of data from eseperisental designs is often hampered by the lack of more than one procedure available for the analysis, especially when that procedure is based on assumptions which do not apply in the situation at hand. In this paper tvo classes of alternative procedures are discussed and compared, One is the aligned ranks procedure which first standardises the data by subtracting an appropriate estimate of location, then replaces the data with ranks t and finally uses an appropriate test statistic which has asymptotically a chi-square distribution The second procedure is the rank transform which first replaces all of the data with the ranks, and then employs the usual parametric methods, but computed on the ranks instead of the data Some Monte Carlo simulations for a test of interaction in a two way layout with replication enable the robustness and pover of these tvo methods to be compared with the usual analysis of variancs.     

从居延汉简看汉代民爵八级的政治地位

据居延汉简简文,汉代民爵八级,从一级公士到八级公乘,在居延屯戍区内既可担任各种官职(实为百石小吏),也可以当兵。当官凭本人才能,与爵位无关,当兵说明爵位八级已失去免役等特权,成为有名无实的荣誉头衔。汉简中反映的公乘当官者多、当兵者少,公士当兵者多、当官者少的情况,说明爵位高低还有一定影响,但这影响是建立在实力基础上的,并无法律保证。汉代这种以才能任官的政策是进步的。     

以"三个代表"为指导,建设一支高素质的干部队伍

建设一支高素质的干部队伍,要坚持以三个代表为指导,切实转变干部作风,不断提高干部的领导水平和抵御凤险、拒腐防变的能力,全面提高干部的素质,在深化干部制度改革中进一步加强对领导干部的监督和管理。     

中国的"制造业吸纳"与区位优势提升

当前,对制造业国际转移的不断吸纳使中国获得了一次难得的发展机会。在今后相当一段时间内,这种吸纳在中国的工业化进程中仍将担当十分重要的角色。然而,中国是否能够继续保持这种吸纳的强劲势头,并在此过程中不断向产品价值链的高位区逼近,将在很大程度上取决于中国能否使自己的区位优势得到保持与提升。     

邓小平人才强国战略思维之育才思想研究

邓小平理论中蕴含丰富的人才强国战略思想,而育才思想是邓小平人才强国战略思想的重要组成部分。其育才思想主要体现在人才标准建构、人才基地建设和人才队伍打造三大方面,三者相辅相成,共同构成邓小平育才思想的有机整体。     

《二年律令》所见二十等爵对西汉初年国家统治秩序的影响

张家山汉简《二年律令》包含较多有关西汉初年二十等爵的史料。从这些史料可以看出,二十等爵与西汉初年国家统治秩序有密切的联系。这种联系表现为,二十等爵与授田制结合,二十等爵国家治安制度结合,二十等爵与养老制度结合,二十等爵与国家赏赐制度结合。二十等爵贯穿于这些制度之中,对稳定西汉初年国家统治秩序,所起到的积极作用,是不可忽视的。     

加强和创新高等学校学生工作的若干思考

学生工作是高等学校党建和思想政治教育工作的重要内容,是培养高素质人才不可或缺的关键环节。加强和创新高等学校学生工作必须全力夯实学生安全稳定这＂一个＂基础,突出把握大学生就业创业、学风建设＂两个＂重点,积极深化大学生心理健康教育、文明创建活动、资助平台建设等＂三项＂建设,努力推进思想政治教育精细化、辅导员队伍建设专业化、学生工作考核评价科学化、学生管理信息化和主题教育品牌化等＂五化＂工作的落实,加强和创新高等学校学生工作。
