Hypothesis testing for quantitative trait locus effects in both location and scale in genetic backcross studies

Testing the existence of a quantitative trait locus (QTL) effect is an important task in QTL mapping studies. Most studies concentrate on the case where the phenotype distributions of different QTL groups follow normal distributions with the same unknown variance. In this paper we make a more general assumption that the phenotype distributions come from a location-scale distribution family. We derive the limiting distribution of the likelihood ratio test (LRT) for the existence of the QTL effect in both location and scale in genetic backcross studies. We further identify an explicit representation for this limiting distribution. As a complement, we study the limiting distribution of the LRT and its explicit representation for the existence of the QTL effect in the location only. The asymptotic properties of the LRTs under a local alternative are also investigated. Simulation studies are used to evaluate the asymptotic results, and a real-data example is included for illustration.     

教师教育“教育学”教材专业化缺失与重构

教师职业专业化呼唤专业化的教育学教材，但现有教师教育“教育学”教材无论内容还是形式大多是教育学学科专业相关教材的“翻版”，缺乏鲜明的专业独立性。作为专业化的职业教育，教师教育教育学教材从专业属性讲不是学科性的，而是与教师职业的典型问题和经验活动密切相关的；从培养目标上看，教育学教材应造就以教师职业能力为核心的专业化人才，而非理论性工作者；从教材形态看，教育学教材应以鲜活的生命性姿态促进学习者的对话、反思、建构，发挥教材的多维教育功能，以期构建属于每个从业者个人的专业化“教育学”。

Integration of Behavioral Frequency and Intention Information in Young Children's Trait Attributions

Two experiments examined three‐ to six‐year‐olds' use of frequency and intention information to make trait attributions and behavioral predictions. In experiment 1, participants were told a story about an actor who behaved positively once or four times on purpose or incidentally. Children were most likely to make trait‐consistent behavioral predictions after hearing about several positive, intentional behaviors. Trait attributions were largely positive. Experiment 2 examined children's use of the same cues concerning negative behavioral outcomes. Participants tended to predict that actors who engaged in negative behavior would do so again, irrespective of intention, although younger children required more exemplars than older children. Participants were most likely to make negative trait attributions after hearing about multiple intentional behaviors; however, there was reluctance with age to describe actors as mean. Implications for children's ‘theory of personality’ are discussed.     

M31. Least squares solutions over interval restrictions

In this article, the three-parameter I.G. distribution is standardized with zero mean and unit variance. The third standard moment α₃ is employed as the shape parameter. Tables of the cumulative probability function are given as a function of the standardized variate z, and of the shape parameter, α₃. Various comparisons are made with the lognormal, Weibull, and gamma distributions.     

中国少数民族服饰的文化内涵及其对外传播探析——以《中国妇女》（英文月刊）为例

本文选择最具代表性的中国文化核心概念之一（天人合一的思想）加以论述,探讨人与自然的四种关系,根据《中国妇女》（英文月刊）中的中国少数民族服饰对外传播材料进行分析。中国少数民族服饰着的是自然的色彩,表的是中华民族的情愫,体现的是中国天人合一的文化精华。本文说明服饰对外传播不是停留在绚丽服饰的浅层次上,而是深深地植根于中国文化的肥沃土壤中,在对外交流中,其承载的中国文化的自然性与西方的神性可以交融互补。中国少数民族服饰对外传播对全球性对话和中国软实力建设具有重要作用。

Comparison of different computational implementations on fitting generalized linear mixed-effects models for repeated count measures

ABSTRACT

In modelling repeated count outcomes, generalized linear mixed-effects models are commonly used to account for within-cluster correlations. However, inconsistent results are frequently generated by various statistical R packages and SAS procedures, especially in case of a moderate or strong within-cluster correlation or overdispersion. We investigated the underlying numerical approaches and statistical theories on which these packages and procedures are built. We then compared the performance of these statistical packages and procedures by simulating both Poisson-distributed and overdispersed count data. The SAS NLMIXED procedure outperformed the others procedures in all settings.
