固体低频内耗力学模型及其测量研究

综述了固体低频内耗的力学模型及其测量的研究进展.固体的内耗有滞弹性和粘弹性内耗,低频内耗常用的测量方法有自由衰减法和强迫振动法.固体内耗的典型力学模型有两参量和三参量的Voigt模型和Maxwell模型,都可用来描述固体内耗,但都有一定局限性,目前还没有一个理想的力学模型来描述粘弹性内耗,尤其是非线性粘弹性内耗.

Attention Demands of Precision Pistol-Shooting as a Function of Skill Level

This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional internal model was retained in which motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Some redundancy among the dimensions was observed. Internal reliabilities ranged from very good to excellent. Practical recommendations for the CCS are given in the Discussion section.     

Exploring Social Theory as a Framework for Social and Cultural Measurements of the Information Society

Using Layder's domain theory (1997) Layder, D. 1997. Modern social theory:Key debates and new directions, London: UCL Press.  [Google Scholar] as an analytical framework, this article shows how the information society can be measured through various levels of society. Layder's notions of psychobiography, situated activity, social setting, and contextual resources help identify cultural and social indicators for understanding changes in the information society. With the help of empirical indicators for each domain, this article uses the case of Estonia to show that there is often more to the information society than what is captured by traditional measures. This article calls for a context-sensitive approach, which takes into consideration social and cultural indicators. Measurements from all four domains are necessary for understanding the complexity of information-society-related issues.     

英语作文论点句的拟定与完善

许多大学生在写作时中心不明确或思路不清晰，给人一种词汇堆砌的感觉。其原因主要是许多学生在写作时不会拟定主题句。而主题句的制定是写好文章的关键。本文就如何构思、如何拟定及如何完善主题句提出一系列建议，希望和同仁及对英文写作感兴趣的师生交流、磋商。     

“资产建设”理论视域下农民工城市创业精准教育与培训研究——基于CHIP数据的分析

迈克尔·谢若登的“资产建设”理论为农民工城市创业精准教育与培训提供了一个恰切的理论视角。CHIP（“中国家庭收入项目调查”数据库,包括“城镇住户”“农村住户”“外来务工住户”三大类调查数据）数据表明:农民工创业比例高,聚集于低端服务业,劳动流转率低,收入较高;社会保险等无形资产累积不足;有形资产具有一定的固定资产累积和闲置资金,但资产配置简单,创业本身负债不显著,资产抗风险能力低。据此,笔者提出将“资产建设”纳入农民工创业精准教育与培训,增加有形资产和无形资产建设内容,依据资产水平建立精准培训筛选机制等发展建议。     

What History Can Teach Us About Science: Theory and Experiment, Data and Evidence

Scientists often use more than the results of experiment to arrive at a result; they use anticipation and analogy to arrive at the results that fit their theories, and sometimes they correct results in the light of analogy. They also need to be clear about the difference between accuracy and precision. They do all this using not only theories, but also apparatus, and the interplay between apparatus and the development of concepts and theories is often crucial. Historians of chemistry (notably including the recent work of Usselman, Rocke, and Holmes) furnish us with plenty of examples of such interplay, and of the selection of data in the light of theory. Lavoisier, Dalton, and Liebig can each teach us a good deal about the way that good scientists arrive at reproducible results.
