自由端摩擦纱捻度结构的理论分析

本文根据在自由端摩擦纺凝聚和加捻过程中纤维的运动规律，推导获得了摩擦纱捻度结构的理论公式。由此公式所得到的摩擦纱的捻度结构形式为外层蓬松，中层紧密，核心无捻。这一结果与实验结果相一致。本文分析表明，摩擦纱这一独特的捻度结构的产生原因是当纤维进入纱尾时将不可避免地发生反向捻回现象，这一现象也是导致摩擦纺加捻效率甚低的主要原因。     

元曲公案戏中的清官与阴阳文化

用我国传统文化中的阴阳理论分析元杂剧公案戏,将压迫者一方视为阳,被压迫一方视为阴,随着双方力量对比的变化,阳可压制阴,阴也可压制阳。清官则高居阴阳之上,调整阴阳运动,维护阴阳平衡,从而达到稳定社会秩序的目的。

The accessibility of contraceptives and service quality in drug stores in Shanghai

This news brief reports findings from a 1996 survey of contraceptive accessibility and service quality in Shanghai, China. Surveys were administered among 100 attendants from 58 drug stores in 5 districts and counties in Shanghai. Drug stores are a primary source of supply of contraception. Findings indicate that 80% of respondents in Nanshi, 85% in Putuo, 45% in Baoshan, 80% in Qingpu, and 70% in Fengxian were satisfied with drug stores as a source of supply of contraception. The mean score on knowledge of contraception among attendants was 68.4; the range was 85.5-27.6. The mean score of ever trained attendants was higher (72.4), compared to 65.8 among untrained attendants. 80% of attendants served customers with consideration and answered questions willingly. Attendants were not able to provide adequate answers to some questions about contraceptives due to deficits in their own knowledge relative to contraception.     

Modeling longitudinal binomial responses: implications from two dueling paradigms

The generalized estimating equations (GEEs) and generalized linear mixed-effects model (GLMM) are the two most popular paradigms to extend models for cross-sectional data to a longitudinal setting. Although the two approaches yield well-interpreted models for continuous outcomes, it is quite a different story when applied to binomial responses. We discuss major modeling differences between the GEE- and GLMM-derived models by presenting new results regarding the model-driven differences. Our results show that GLMM induces some artifacts in the marginal models at assessment times, making it inappropriate when applied to such responses from real study data. The different interpretations of parameters resulting from the conceptual difference between the two modeling approaches also carry quite significant implications and ramifications with respect to data and power analyses. Although a special case involving a scale difference in parameters between GEE and GLMM has been noted in the literature, its implications in real data analysis has not been thoroughly addressed. Further, this special case has a very limited covariate structure and does not apply to most real studies, especially multi-center clinical trials. The new results presented fill a substantial gap in the literature regarding the model-driven differences between the two dueling paradigms.     

Statistical methods for handling missing data to align with treatment policy strategy

The International Council for Harmonization (ICH) E9(R1) addendum recommends choosing an appropriate estimand based on the study objectives in advance of trial design. One defining attribute of an estimand is the intercurrent event, specifically what is considered an intercurrent event and how it should be handled. The primary objective of a clinical study is usually to assess a product's effectiveness and safety based on the planned treatment regimen instead of the actual treatment received. The estimand using the treatment policy strategy, which collects and analyzes data regardless of the occurrence of intercurrent events, is usually utilized. In this article, we explain how missing data can be handled using the treatment policy strategy from the authors' viewpoint in connection with antihyperglycemic product development programs. The article discusses five statistical methods to impute missing data occurring after intercurrent events. All five methods are applied within the framework of the treatment policy strategy. The article compares the five methods via Markov Chain Monte Carlo simulations and showcases how three of these five methods have been applied to estimate the treatment effects published in the labels for three antihyperglycemic agents currently on the market.     

京津冀区域大气污染现状、治理难点及协同治理路径

近年来,京津冀区域整体空气质量形势严峻,偏重的产业结构加剧了大气污染的程度和治理难度。大气污染治理具有艰巨性、复杂性和长期性,面临治理成本较高的问题;区域发展不平衡、治理主体间的利益竞争以及生态补偿的缺失等影响了大气污染协同治理的积极性。基于此,需要建立区域利益补偿机制、推动区域科技联动机制、协调区域政府间的利益公平机制、构建区域相关主体协同治理机制,从而实现京津冀区域大气污染的联防联控和协同治理。     

被“妖魔化”的女大学生,谁来为你正名？——福州大学城某高校女大学生婚育观调查

女大学生作为同龄女性中的佼佼者,她们对爱情的不同体验、不同选择,不仅关系到其自身的发展与成才,更关系到校园文化的建设与社会风气的导向,甚至关系到中国未来社会的发展与稳定。文章以福州大学城某高校大一、大二、大三的三个年级各100名女生为调查对象,分了其恋爱观、婚育观。其恋爱观、婚育观理性、现实,趋于成熟;理想化的成份渐渐褪去。对当代女大学生的婚恋观进行理性思考是高校思想政治工作不容忽视的课题之一。

跨文化交际中的非言语行为

正确理解对方的有声语言并不一定意味着跨文化交际的成功。非语言交际在跨文化交际中起着重要的作用。它包括身势语、体触语面部表情等等。而同一种非言语行为如身势语 ,体触语 ,在不同的国家可能有不同的涵义。因此本文旨在介绍几种跨文化交际中使用比较频繁的非言语行为 ,比较不同国家的异同 ,促进跨文化交流的目的
