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. 相似文献

不同练习手段组合对田径跳跃运动员专项力量训练效果的实验研究 总被引:6,自引:1,他引:5
选择八种常用手段,将三种双腿跳跃练习进行组合,另把五种单腿跳跃练习进行组合,对两组14名跳跃项目运动员进行8周的训练,获取了5项身体素质和BIODEX等速测力仪及KISTLER三维测力台的各项指标训练前后的测试数据.实验研究发现,不同的力量练习手段对人体作用是不一样的,轻负荷、重负荷、单腿练习、双腿练习对人体肌肉的影响有各自的特异性.因此,在力量训练中,选择正确而有效的手段和适宜的运动负荷与强度,把各种不同手段进行合理组合,才能求得最佳的综合整体效益. 相似文献

A modern approach to the diagnosis of artistic heritage makes use of non-destructive techniques which avoid damage to artworks or signs of interaction with the analytical technique used. For this reason, today, the employment of X-rays to study artistic heritage is quite widespread. Computed tomography (CT) Imaging was first used as specialized medical diagnostic tool in the early 1970s. Today, CT scanners have become more common, and non-destructive three-dimensional imaging has found an increasing number of uses in different areas such as materials research, geology, archaeology, and museum conservation. In this work, a new generation of clinical CT (based on the Dual Energy and multi-slice acquisition principle) is used to investigate an Egyptian wooden mummy board with a total acquisition time of 93.23 seconds and a voxel size of 0.078?×?0.078?×?1.5?mm. The use of two distinct techniques of image post-processing, the two-dimensional multi-planar reconstruction (MPR) and the three-dimensional volume rendering technique (VRT) allowed us to: evaluate the state of conservation of the mummy board, determine how the wooden object was implemented, recognize a nineteenth-century intervention of consolidation, and advance the hypothesis that the wooden planks were reused. In particular, we highlight the use of the cardiovascular and pulmonary filter with VRT reconstruction, which allows a virtual elimination of different parts of the mummy board to investigate those areas otherwise accessible only by removing parts of the board and thus damaging the work. 相似文献

Recent articles on the gifted self are characterized by theoretical confusion and lack of definitional clarity. This article, anchored in current self psychology theory, defines the self experience as the person's subjective experience of organization and meaning, the maintenance of which is crucial to normal functioning. Interactions with others are a formative part of the self experience. Traits of giftedness, and the reactions of others to these, contribute to the gifted self experience. Social and emotional problems of giftedness, such as those that arise with asynchronous development and perfectionism, are based on a compromised sense of cohesion and unity of the self experience. 相似文献

主观世界的心理物质、自我心理和心理社会三个心理区域称为主观世界的三维空间。心理素质的发展实质就是在教育和环境的影响下,自我心理世界内部的和谐变化导致的心理物质和心理社会世界三维心理空间的膨胀。研究心理三维空间目的主要是为了探讨主观世界的运动的量变转化为质变机制,从而更好地研究不同个体的心理素质特征,为心理健康教育和心理素质教育提供理论依据。在辩证唯物主义指导下,结合客观世界的运行规律,研究主观世界运行规律和机制,科学系统地构建心理世界的三维空间理论对于研究个体心理素质的和谐发展,提高个体的心理健康水平,建立具有中国特色的原创心理学理论具有重要的现实意义。 相似文献
