Measuring labour market success: a comparison between immigrants and native-born Canadians using PIAAC

Canadian society is characterised by a plurality of immigrants and Canadian migration policy and corresponding recognition approaches are strongly geared to economic criteria, qualifications and skills. This paper addresses the question how immigrants who have acquired their highest qualification outside Canada are able to use their foreign qualifications and skills in their current job. The analyses are conducted to verify the assumptions of human capital theory as well as the lack of transferability of human capital across country borders. To answer these questions a labour market success index is developed, which is used as a dependent variable in regression models. The results show that traditional operationalisations of human capital (years of education, years of work experience and skills) have a positive effect on individual labour market success. At the same time, being born abroad and having acquired one’s highest qualification abroad in comparison to Canada, especially in a Non-Western country, has negative effects on the overall labour market success of an individual. Detailed comparisons regarding different indicators of labour market success also prove these comparatively negative effects. The results demonstrate the limited explanatory power of human capital theory and the necessity to complement it with Bourdieu’s concepts of social and cultural capital.     

Teacher Perceptions of Parent Engagement at a Cyber High School

A growing number of adolescents are taking all or most of their courses online. This places a greater responsibility on parents to support and facilitate their students' learning. This case study used teacher surveys and interviews to better understand how teachers perceived and supported parents' attempts to support their online students at a single online charter school. The results indicated that teachers observed multiple ways in which parents supported their students by (a) organizing and managing students' schedules, (b) nurturing relationships and interactions, (c) monitoring and motivating student engagement, and (d) instructing students when necessary. However, teachers believed that parents could act as obstacles to their students' learning by being overly engaged in certain types of learning activities. Additional research is needed that examines parent engagement in a variety of online learning environments. Research that identifies best practices could also be especially valuable to online teachers and administrators wishing to improve the quantity and quality of parental engagement in their programs.

ICT/media uses and college entry for students from diverse backgrounds

This study examined the effects of two types of Information communication technology and media (ICT/media) use on college access using ICT/media to obtain college information as a mediator paying focused attention to English language learners. The study analyzed the Educational Longitudinal Study (ELS) from the US Department of Education, employing a survival analysis with structural equation modeling components. The results demonstrated that the frequent use of a computer for independent learning had significantly positive direct, indirect, and total effects on college entry for both English language learners and native English-speaking students. However, the digital gameplay had significantly negative effects. The study discusses the implications of using ICT/media.     

BAF复合物和转录因子NF1/CTF与RNA聚合酶Ⅱ的联系

BAF是哺乳动物细胞中的染色体改构复合物,通过重构核小体的结构来促进基因的转录活动·NF1/CTF是一种重要的转录因子,可以和CCAAT-box结合,参与基因转录活动.有研究表明,BAF复合物与糖皮质激素共同作用可以增加NF1/CTF转录活性[1,2].另有文献报道在CSF-1启动子上,BAF复合物激活

Strengthening ‘the foundations’ of the primary school curriculum

The low status of the foundation subjects (e.g. Music and Physical Education (PE)) in English primary schools is well documented. Using PE as an illustrative example, a thematic analysis of 51 PE trainee students’ assignments, based on their perceptions of a two-week experience in a primary school, highlighted a number of areas of concern (e.g. limited/inadequate preparation; insufficient teacher knowledge/confidence; variable/limited subject leadership and non-qualified teachers delivering the curriculum). The possibility of teachers, coaches and other external specialists learning collaboratively with and from each other within a community of practice/learning is proposed as one way of strengthening the foundation subjects within the primary school curriculum.
