Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.     

A meta-cognitive approach to doping in sports: The effects of thought validation on attitudes related to doping

ABSTRACT

To better understand doping-related attitude change, it is important to consider not only the amount of thinking (i.e., elaboration) done by message recipients, but also the favourability of their thoughts in response to the proposal, as well as the perceived validity in their thoughts. The main goal of the present study was to analyse the effects of a meta-cognitive process (i.e., thought validation) on attitudes related to doping. Thus, we randomly assigned participants to read a message either against or in favour of legalising several doping behaviours. Participants listed their thoughts regarding the proposal and indicated the perceived validity in their thoughts, then reported their attitudes. As hypothesised, the message against legalisation elicited more unfavourable thoughts and attitudes than the message in favour of legalisation. Most relevantly, the effects of the message direction on attitudes were greater for participants with higher (vs. lower) levels of thought validity. Furthermore, consistent with the thought validation process, results revealed that thought favourability was a better predictor of attitudes for participants with higher (vs. lower) perceived thought validity, indicating that perceiving one’s thoughts as valid plays an important role in persuasion. These findings provide novel insights for research and interventions regarding doping in sports.     

我国体育新闻传播教育的现状、问题及发展方向

采用文献资料和实证调查等研究方法,对我国体育新闻传播教育状况进行研究。认为:由于新闻事业和体育事业的迅猛发展以及国家教育政策的调整,使我国体育新闻传播专业办学规模不断扩大,呈现报考和招收人数持续上升与体育新闻传播专业教育“硬件不硬、软件太软”的矛盾。提出:应遵循体育新闻传播教育的办学规律,进一步整合资源,调整结构,加强软、硬件建设,提高教学质量,实现体育新闻传播教育的可持续发展。     

军事体能训练的大脑机能能力和特征研究

采用测量实验法对大脑机能能力与军事体能训练评定体能等级的相关性进行研究，发现大脑机能能力和特征的稳定、均衡和灵活能提高体能评定水平。同时，不同大脑机能能力被试在体能训练的发展上存在明显的差异，即体能评定等级高大脑机能能力较强。

如何认识和控制我国当前的财政债务规模

我国财政债务规模包括中央财政规模和隐性、或有债务规模。为此,只有全面认识财政债务的实际规模,并分析其不断扩大的原因,才能在实践中采取有效措施,控制和缩减当前的财政债务规模。     

西部大开发战略的经济学思考

西部大开发战略的提出标志着我国经济发展战略的重大转变,也是实现经济均衡发展的重要举措,如何实现西部经济快速起飞,关键在于实现三个转变：经济发展战略从“梯度推移论”到西部跳跃发展;经济发展环境从偏向沿海地区向西部地区转移;经济发展重点从城市偏向改革到注重农村市场开拓。     

强光束小尺度调制的非线性演化规律

Bespalov-Talanov关于小尺度自聚焦的经典理论在调制场的非线性演化阶段不适用。本文将这个理论推广到大信号非线性增长情形。结果表明，小尺度调制场和本底场在传输过程中经历周期性的能量交换过程。数值模拟验证了解析结果。
