纳西祭仪中隐含的文化主题

纳西人把祭天视为每年周期性举行的最为重要的仪式。祭天仪式中的三颗神树分别被称为美、达、许,即天神、地神和中央许神。在祭天的这则迎娶天女的神话中,透露的是一个纳西社会母系与父系错综的婚姻与繁衍生殖乃至于社会关系变迁的历史。     

体育——构建和谐社会的新力量

党的十六大把“社会更加和谐”作为全面建设小康社会的目标之一提出来，党的十六届四中全会又把“提高构建社会主义和谐社会的能力”作为党执政能力的一个重要方面明确提出。为了实现这一目标，各行各业都要为此付出坚实的努力，体育界同样如此。体育是构建和谐社会的重要力量之一。     

和谐社会视域下的效率观

构建社会主义和谐社会,是我们党以马克思列宁主义、毛泽东思想、邓小平理论和“三个代表”重要思想为指导,全面贯彻落实科学发展观,从中国特色社会主义事业总体布局和全面建设小康社会全局出发提出的重大战略任务。如何全面贯彻和落实党的十六届六中全会精神,构建和谐河南,成为摆在我们面前的一项迫切的历史任务。《和谐社会视域下的效率观》一文,以科学发展观为统领,以和谐社会的视域重新审视效率,阐述了效率与和谐的正相关性与负相关性,倡导确立科学的效率观。建设和谐社会,各级政府承担着重要责任。《政府责任与经济社会生活秩序》一文,针对市场经济的不发达与市场缺陷两大问题并存的现实,提出应在政府与市场、企业、社会、公民的多维关系中认识政府责任,并切实履行其责任。《构建和谐中原重在培育和谐发展的思维方式》一文指出,科学发展观本质上是一种和谐发展的新理念,也是一种全新的思维方式。转变河南干部群众原有的思维方式,培育和谐发展新思维,同样是构建和谐河南的一项重要任务。     

在先验与经验之间——论哈贝马斯普遍语用学的经验与先验问题

哈贝马斯普遍语用学是经验性的,但其是在先验的规范分析的操作下进行的,不是经验主义的;同时,哈贝马斯普遍语用学又是先验性的,但却是诉诸经验分析的。哈贝马斯普遍语用学的经验与先验的二重性在交互主体理想的交往情景的持续重建中葆有一种内在的张力。     

归化还是异化——谈影响翻译策略选择的若干因素

归化和异化作为两种翻译方法或翻译策略,从根本上讲是在原语和译语间存在差异的基础上产生的。在翻译实践中,译者选择归化或异化的翻译策略要受到多种因素的影响,如原作文本类型、译者的语言水平、译者的翻译目的、译作读者水平、原语文化和译语文化的强弱等。多数情况下,归化论者和异化论者都努力保持一种平衡以避免走向极端。     

确定抽油杆疲劳断裂常数的一种实用统计方法

针对疲劳裂纹扩展性能的统计性质,提出了一种确定抽油杆疾劳断裂材料常数的实用方法,该方法确定出的常数位与存活率相对应,与其它方法的结论基本一致。对抽油杆疲劳裂纹扩展寿命的分布和常数c与m之问的关系作了初步脸证。

Parenting Practices,Autonomous Motivation,and Adolescent Diet Habits

Guided by self‐determination theory, the aim of this study was to examine whether adolescents’ autonomous motivation for making healthy diet choices mediates the association between parenting practices regarding diet and adolescent food choices. We analyzed data from the NCI FLASHE study, a survey of demographically diverse parents and their adolescent children (N = 1,646 dyads). Path models supported self‐determination theory’s assertion that indirect, encouraging parenting practices fostered internal motivation; in contrast, regulation was both positively and negatively linked to motivation depending on the model. Models also yielded direct paths between parenting practices and healthy and unhealthy diet choices. Overall, regardless of what predicted motivation, adolescents’ autonomous motivation was linked with their consumption of healthier foods and drinks. As such, cultivating a sense of internal motivation during these formative years may put young people on a path toward healthy patterns of self‐regulation later in life.     

Estimation of the additive hazards model with interval-censored data and missing covariates

The additive hazards model is one of the most commonly used regression models in the analysis of failure time data and many methods have been developed for its inference in various situations. However, no established estimation procedure exists when there are covariates with missing values and the observed responses are interval-censored; both types of complications arise in various settings including demographic, epidemiological, financial, medical and sociological studies. To address this deficiency, we propose several inverse probability weight-based and reweighting-based estimation procedures for the situation where covariate values are missing at random. The resulting estimators of regression model parameters are shown to be consistent and asymptotically normal. The numerical results that we report from a simulation study suggest that the proposed methods work well in practical situations. An application to a childhood cancer survival study is provided.

Bayesian sample‐size determination methods considering both worthwhileness and unpromisingness for exploratory two‐arm randomized clinical trials with binary endpoints

A randomized exploratory clinical trial comparing an experimental treatment with a control treatment on a binary endpoint is often conducted to make a go or no‐go decision. Such an exploratory trial needs to have an adequate sample size such that it will provide convincing evidence that the experimental treatment is either worthwhile or unpromising relative to the control treatment. In this paper, we propose three new sample‐size determination methods for an exploratory trial, which utilize the posterior probabilities calculated from predefined efficacy and inefficacy criteria leading to a declaration of the worthwhileness or unpromisingness of the experimental treatment. Simulation studies, including numerical investigation, showed that all three methods could declare the experimental treatment as worthwhile or unpromising with a high probability when the true response probability of the experimental treatment group is higher or lower, respectively, than that of the control treatment group.
