Where do you come from,where do you go? Assessing skills gaps and labour market outcomes for young adults with different immigration backgrounds     

《International Journal of Educational Development》2021

Using PISA and PIAAC data from twelve OECD countries, we examine the gap in cognitive skills among immigrants and natives and evaluate how those differences have evolved over time. We also consider how demographics, family background and school quality explain the development of cognitive skills of young people with immigrant backgrounds. The results show, first, that some convergence in skills occurs between second-generation immigrants and natives over time. Second, demographics, family background and school quality variables all contribute to the achievement gaps across different groups.  相似文献

我国马拉松跑者深度休闲特质的质性研究     

田海波  周文婷  邱亚君  齐震 《沈阳体育学院学报》2020,(1):54-60

在"马拉松热"的背景下,对跑步参与过程中马拉松跑者的深度休闲特质进行探究。采用滚雪球抽样方式,对20名马拉松跑者进行半结构式访谈,通过质性分析软件NVivo 11.0对访谈资料进行分析。研究结果表明马拉松跑者具有深度休闲的6个特质:坚持不懈、生涯性、显著的个人努力、强烈的认同感、独特的文化、持久的收益。本研究进一步丰富了已有研究成果,其中坚持不懈中的"毅力"和"自我管理"两方面体现了马拉松项目的特点。对马拉松跑者来讲,经济回报和团队发展并不是明显的持久收益。本研究结果拓展了对我国"马拉松热"现象的理解,未来应采用定量方法进行深入研究。  相似文献   

A mathematical model for decision-making in the classification of para-footballers with different severity of coordination impairments     

Diego Pastor  María Campayo-Piernas  Jesús Tadeo Pastor 《Journal of sports sciences》2019,37(12):1403-1410

Classification is a defining feature of Para-sport, and sports-specific classification systems determined through multidisciplinary scientific research are required, i.e., evidence-based and focused on the relationship between the impairment and the key performance determinants. Data envelopment analysis (DEA) was applied as a classification tool using a directional distance function (DDF) model. The aim of the study was to test the DEA as a possible classification tool in cerebral palsy football. We analyse the performance of 56 international para-footballers with hypertonia, ataxia or athetosis, who completed a 20-test battery with DEA models. Five of the tests are included in the model (change of direction: Illinois agility test; jumping: standing broad jump, four bounds for distance, and triple hop with the non-dominant leg; 10-m sprint/acceleration; and ball dribbling, both in a straight line and following a trajectory), showing that players with less impairment exhibit the highest efficiency. This outcome suggests that DEA models might be feasible for detecting and discriminating the performance and magnitude of impairment in cerebral palsy football, with an objective ranking of the athletes in relation to different physical performance tests. This study also provides reference scores for decision-making during classification and guidance for further research in team Paralympic sports.  相似文献   

Using the Information Structure Model to Compare Profile-Based Information Filtering Systems     

Yuval Elovici  Bracha Shapira  Paul B. Kantor 《Information Retrieval》2003,6(1):75-97

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher.  相似文献
