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   

Rethinking participation in the Aarhus as European Capital of Culture 2017 project     

Leila Jancovich  Louise Ejgod Hansen 《Cultural Trends》2018,27(3):173-186

This paper examines the relationship between cultural participation and regional development with reference to the European Capital of Culture in 2017. From the bidding stage, Aarhus 2017 claimed it put “participation” at the heart of its strategic plans, through consultation at roadshows and exhibitions. In addition, it aspired to use culture as a catalyst for development not only in the city of Aarhus but across the region of Central Denmark. This paper, therefore, examines how participation is defined and implemented to address regional development in the Aarhus 2017 process through textual analysis of documentation from Aarhus 2017 and delivery partners as well as over 20 interviews with managers and participants involved in a range of 2017 projects. The paper argues against the common prioritisation of urban and professional cultural institutions and makes the case for decentralised cultural provision that supports both amateurs and professionals through a regional networked structure.  相似文献   

Tracking user-role evolution via topic modeling in community question answering     

Chaogang Fu 《Information processing & management》2019,56(6):102075

Community question answering (CQA) services that enable users to ask and answer questions are popular on the internet. Each user can simultaneously play the roles of asker and answerer. Some work has aimed to model the roles of users for potential applications in CQA. However, the dynamic characteristics of user roles have not been addressed. User roles vary over time. This paper explores user representation by tracking user-role evolution, which could enable several potential applications in CQA, such as question recommendation. We believe this paper is the first to track user-role evolution and investigate its influence on the performance of question recommendation in CQA. Moreover, we propose a time-aware role model (TRM) to effectively track user-role evolution. With different independence assumptions, two variants of TRM are developed. Finally, we present the TRM-based approach to question recommendation, which provides a mechanism to naturally integrate the user-role evolution with content relevance between the answerer and the question into a unified probabilistic framework. Experiments using real-world data from Stack Overflow show that (1) the TRM is valid for tracking user-role evolution, and (2) compared with baselines utilizing role based methods, our TRM-based approach consistently and significantly improves the performance of question recommendation. Hence, our approach could enable several potential applications in CQA.  相似文献

高校田径教学存在的问题及对策研究     

陶月  王磊 《体育科技文献通报》2020,(2):59-60,99

在高校教育中,田径课程是一门价值深远的体育课程,它不仅有增强人体机能、改善体内系统的效能,同时还有拓展视野、扩大交际范围和增强自我能力的作用,作为在高校体育中占有重要位置的一门课程。在社会经济不断深入发展的历史新时期里,传统的田径教学同大学生的自我能力发展要求已经不相适应,本文在此基础上,总结了几点主要问题和几项解决措施,希望能够为相关高校的田径教学工作者提供参考。  相似文献   

从传统走向现代：瑜伽精神实践的认知转向与模式转型     

刘丽云 《体育学刊》2020,(1):25-29

探讨了瑜伽现代化过程中精神实践的认知转向与推广模式转型及其影响。瑜伽在传统文化环境中是印度本土宗教中实现宗教目的的修行方式,是传统哲学中达到自我完满状态的重要途径,是通过离群苦修达到“梵我合一”的手段。在现代化过程中,瑜伽通过融合心灵哲学、引入世俗目标、融入现实生活等方式实现了精神实践的认知转向。在现代瑜伽推广过程中,通过增强主体的多元性、形式的时代性、内容的功能性等方式实现了推广模式的转型,为世界“瑜伽热”提供助力,也为中国传统体育运动的发展传播提供了启示。  相似文献

儒家“五常”思想在大学生创新创业精神培育中的运用     

肖华碧 《清远职业技术学院学报》2020,(2):82-85

中国儒家“五常”思想承载了丰富的创新创业品质。高校创新创业教育应从儒家“五常”思想中汲取精髓,深入挖掘其中有助于培育大学生创新创业教育的思想资源,积极将儒家“五常”思想融入大学生创新创业精神培育的全过程。儒家“五常”思想与大学生创新创业精神培育在修身立业、财富积累、人际交往、终身学习、信誉至上等观念的培养上具有高度的契合性。儒家“五常”思想融入大学生创新创业教育,需要在观念、思想和文化上与时俱进,实现“三个转变”,设置切实可行的实践路径。  相似文献   

离岸集装箱码头新装卸工艺模式下陆域集疏运堆场堆存空间分配     

杨晓斌  余思勤  沈一帆 《上海海事大学学报》2020,41(4):8-14

离岸集装箱码头因其岛屿面积限制，难以通过扩建码头内部堆场增加吞吐能力。为解决这个问题，提出一种离岸集装箱码头新装卸工艺模式。新装卸工艺模式是通过在离岸集装箱码头附近的陆域地带建设陆域集疏运堆场,与离岸集装箱码头进行协同装卸作业的模式。陆域集疏运堆场堆存空间分配的目标是满足离岸集装箱码头装卸作业预翻倒要求;单批次输送集装箱的量受到陆岛运输最大通行能力限制。根据上述目标与特点，构建新装卸工艺模式下陆域集疏运堆场堆存空间分配模型，并设计蒙特卡洛树搜索算法进行求解。通过算例分析验证模型的有效性。结果表明该方法能够满足陆域集疏运堆场堆存空间分配需求并提高离岸集装箱码头的吞吐能力。  相似文献
