关于反腐倡廉对策的思考

理想教育、宗旨教育、传统教育、法制教育是反腐倡廉的基础。完善制度、健全法律 ,严格依法办事是反腐倡廉的保证。普及权力监督意识、强化监督功能 ,健全监督机制、增强监督力度 ,狠抓落实问题 ,使监督落到实处 ,是反腐倡廉的关键。只有三管齐下 ,反腐倡廉才能真正取得实效     

“拈花惹草”补释

对成语“拈花惹草”，几部常见常用、影响很大的辞书，将其词义释为“指男子乱搞男女关系或狎妓”“比喻(男子)挑逗、勾引异性”。这些释义是有问题的，至少是不够准确的；它与一些典范的作品的用例是不相符的。这样的释义会误导人们对“拈花惹草”的正确运用。“拈花惹草”的词义可补释为：拈，用手指夹、捏取物，引申为“习弄、摆弄、玩弄”；惹，招引、挑逗；花、草，借指异性。比喻挑逗、玩弄异性；今多比喻男子挑逗、勾引、玩弄异性。     

适当放宽年龄限制 充分发掘人力资源——对人才招聘年轻化的再思考

知识经济的初见端倪使得终生教育成为 2 1世纪社会发展的必然趋势。许多在职人员为了适应社会发展的需要重返校园 ,继续深造。但传统的人事制度对人才年轻化的要求日益影响着这些人的重新就业 ,从而直接影响了在职人员对终生教育的热情。本文拟从教育部最近取消高考年龄及婚否限制的政策分析入手 ,通过剖析现行人事制度中年轻化要求的历史背景及其在现实中的局限性 ,阐明适当放宽大龄毕业生重新就业年龄限制的必要性及其现实意义     

金融危机视域中的农民工再就业及其法律应对——从“被动返乡”农民工谈起

金融危机的冲击使得我国沿海地区外贸依存度很高的劳动密集型企业关停并转，导致大批农民工“被动返乡”，从而使得农民工再就业问题凸显。解决农民工再就业问题需要从多方面入手，其重要途径是依靠法律。强化农民工就业的法律保障，是要求树立以人为本的法律理念、完善农民工就业的法律规定、严格施行农民工就业的法律规定。     

Increasing the sample size at interim for a two‐sample experiment without Type I error inflation

For the case of a one‐sample experiment with known variance σ²=1, it has been shown that at interim analysis the sample size (SS) may be increased by any arbitrary amount provided: (1) The conditional power (CP) at interim is ?50% and (2) there can be no decision to decrease the SS (stop the trial early). In this paper we verify this result for the case of a two‐sample experiment with proportional SS in the treatment groups and an arbitrary common variance. Numerous authors have presented the formula for the CP at interim for a two‐sample test with equal SS in the treatment groups and an arbitrary common variance, for both the one‐ and two‐sided hypothesis tests. In this paper we derive the corresponding formula for the case of unequal, but proportional SS in the treatment groups for both one‐sided superiority and two‐sided hypothesis tests. Finally, we present an SAS macro for doing this calculation and provide a worked out hypothetical example. In discussion we note that this type of trial design trades the ability to stop early (for lack of efficacy) for the elimination of the Type I error penalty. The loss of early stopping requires that such a design employs a data monitoring committee, blinding of the sponsor to the interim calculations, and pre‐planning of how much and under what conditions to increase the SS and that this all be formally written into an interim analysis plan before the start of the study.

青海地区古代农业的起源与发展

青海地区农业起源可追溯到六千年前。中国历代王朝及青海地方官员都先后采用“戍边屯田”、“移民屯田”、交流引进、教民农桑、引进先进的生产工具和农耕技术、兴修农田水利等促进措施,推动农业生产不断进步。     

论尼采的政治哲学

弗里德里希·威廉·尼采 ( Friedrich Wilhelm Nietzsche,公元 1 844— 1 90 0年 )是德国由自由资本主义向帝国主义过渡时期最敏锐地反映资产阶级要求的哲学家和政治思想家。他的政治哲学形成于 1 9世纪 70— 80年代。他从当时德国资产阶级实际发展的状况出发 ,宣称要摧毁“一切旧的价值体系”,并重新估价一切价值 ,创立以“权力意志”论为基础 ,以“超人”学说为核心的强者的价值体系。尼采的政治哲学就是建立在这种价值体系之上的 ,具有浓重时代气息的社会政治思潮 ,对当时德国资本主义的发展产生了重要影响     

Practical approaches for design and analysis of clinical trials of infertility treatments: crossover designs and the Mantel–Haenszel method are recommended

Crossover designs have some advantages over standard clinical trial designs and they are often used in trials evaluating the efficacy of treatments for infertility. However, clinical trials of infertility treatments violate a fundamental condition of crossover designs, because women who become pregnant in the first treatment period are not treated in the second period. In previous research, to deal with this problem, some new designs, such as re‐randomization designs, and analysis methods including the logistic mixture model and the beta‐binomial mixture model were proposed. Although the performance of these designs and methods has previously been evaluated in large‐scale clinical trials with sample sizes of more than 1000 per group, the actual sample sizes of infertility treatment trials are usually around 100 per group. The most appropriate design and analysis for these moderate‐scale clinical trials are currently unclear. In this study, we conducted simulation studies to determine the appropriate design and analysis method of moderate‐scale clinical trials for irreversible endpoints by evaluating the statistical power and bias in the treatment effect estimates. The Mantel–Haenszel method had similar power and bias to the logistic mixture model. The crossover designs had the highest power and the smallest bias. We recommend using a combination of the crossover design and the Mantel–Haenszel method for two‐period, two‐treatment clinical trials with irreversible endpoints.
