The advantage of mixing examples in inductive learning: a comparison of three hypotheses

Mixing examples of different categories (interleaving) has been shown to promote inductive learning as compared with presenting examples of the same category together (massing). In three studies, we tested whether the advantage of interleaving is exclusively due to the mixing of examples from different categories or to the temporal gap introduced between presentations. In addition, we also tested the role of working memory capacity (WMC). Results showed that the mixing of examples might be the key component that determines improved induction. WMC might also be involved in the interleaving effect: participants with high spans seemed to profit more than participants with low spans from interleaved presentations. Our findings have relevant implications for education. Practice schedules should be individually customised so society as a whole can profit from differences between learners.     

Key somatic variables associated with,and differences between the 4 swimming strokes

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).

高职思政课实践教学与工学结合叠加教学探索

实践教学是思政课及工学结合不可或缺的重要组成部分。积极推进思政课实践教学与专业顶岗实习的有机结合，重构与工学结合相适应的思政课实践教学体系，以发挥二者间的叠加教学效应。这既是高职培养“全面发展和适应社会需要”的人的题中应有之意，也是高职思政课实践教学改革要着力探索的一种新型方式和途径。     

论网络环境下的高校思想政治工作创新

网络条件下思想政治工作与传统思想政治工作相比，具有民主化、信息化、社会化等时代特征。现代网络技术为当代高校思想政治工作带来发展机遇的同时，也带来了严重的负面影响。因此，必须从如下几个方面创新高校思想政治工作机制：理顺管理体制；加强网络研究，探索传播规律；强化法制意识，规范网上行为；采用新的工作内容、方法和技术。     

Thermographic analysis of bronze sculptures

In this work we investigate various aspects of the finishing process in ancient bronze sculptures by means of active infrared thermography (IRT). Active IRT provides information on surface and sub-surface features of the investigated artefact, by analysing the heat diffusion process induced within the sample by appropriate thermal stimulations usually produced by absorption of light emitted by different sources. The aim of this research is, in particular, to investigate the processing of bronze surfaces, revealing repairs like plugs, fillings, local castings and concealed marks.
