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

Team identification and sports fandom as predictors of fan aggression: The moderating role of ageing     

《Sport Management Review》2019,22(2):194-208

In the current study, the explored the moderating role of ageing in the relationship between team identification/fandom and fan aggression. The authors used an online panel-based survey that offered access to a realworld population of sports fans. Participants were 740 fans of Israeli professional basketball. Results from structural equation modelling demonstrated that older fans reported higher levels of mere sports fandom and lower levels of self-reported aggression and acceptance of aggression. Moreover, age moderated the relationships between team identification (or fandom) and self-reported aggression, such that team identification (or fandom) was more strongly associated with selfreported fan aggression among younger fans than among older fans. The moderating role of age in the relationships between team identification (or fandom) and perceptions of appropriateness of aggression was not supported. The findings contribute to our theoretical understanding of the role of ageing in the relationship between fan identification and fan aggression. Based on these findings, the authors assert that managers might particularly benefit from leveraging the potential, but often neglected, segment of senior fans, since older fans can play a key role in reducing the level of aggression during competitive sports events. Suggestions for future research are also discussed.  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
