Motivation and Attribution at Secondary School: The role of ethnic group and gender

Some 985 secondary school students completed a questionnaire as part of an investigation into the experiences of Asian girls in a secondary school arising out of a larger project concerned with motivational factors in educational attainment. Results indicated that (1) Asian girls enjoyed all aspects of school life as much or more than their non-Asian counterparts; (2) across both ethnic groups girls enjoyed all aspects of school except sports and clubs more than boys; (3) enjoyment of subjects followed sex stereotypical lines, irrespective of ethnicity: girls rated English, French, German, drama, music and home economics as significantly more enjoyable, and boys rated science, craft, design and technology, physical education, information technology and mathematics as more enjoyable; (4) irrespective of gender, Asian students reported more enjoyment of religious education, and lower enjoyment of drama, physical education and home economics; (5) irrespective of ethnic group, girls reported that there was not enough choice of subjects; and (6) Asian students of both sexes rated parents and friends as more important in contributing to academic success. These results are critiqued in a context that questions the desirability of conducting investigations such as this which dichotomise students into groups on the grounds of ethnicity.     

A typology for a social justice approach to assessment: learning from universal design and culturally sustaining pedagogy

This paper aims to provide a tentative roadmap for ensuring that higher education policy makers and practitioners are apprised of what might be done to advance a concept of socially just assessment praxis. It extends current thinking around the notion of social justice approaches to assessment by further developing the conceptual framework proposed in McArthur's recent work (2016). It does so by extending understandings of how a socially just perspective might be realised. Drawing upon recent conceptual developments within both Universal Design for Learning (UDL) and Culturally Sustaining Pedagogy (CSP), the paper proposes a typology for praxis and organisational change. Crucially, this typology focuses upon enhancing learning outcomes for all learners, but it is particularly concerned with enhancing educational experiences and learning outcomes for students that have been systematically marginalised by the normative procedural practices that have traditionally informed the nature of supposedly objective assessment.     

Inhibitory activities of microalgal extracts against Epstein-Barr virus DNA release from lymphoblastoid cells

This study aimed to assess the inhibitory activities of methanol extracts from the microalgae Ankistrodesmus convolutus, Synechococcus elongatus, and Spirulina platensis against Epstein-Barr virus (EBV) in three Burkitt's lymphoma (BL) cell lines, namely Akata, B95-8, and P3HR-1. The antiviral activity was assessed by quantifying the cell-free EBV DNA using real-time polymerase chain reaction (PCR) technique. The methanol extracts from Ankistrodesmus convolutus and Synechococcus elongatus displayed low cytotoxicity and potent effect in reducing cell-free EBV DNA (EC(50)<0.01 μg/ml) with a high therapeutic index (>28000). After fractionation by column chromatography, the fraction from Synechococcus elongatus (SEF1) reduced the cell-free EBV DNA most effectively (EC(50)=2.9 μg/ml, therapeutic index>69). Upon further fractionation by high performance liquid chromatography (HPLC), the sub-fraction SEF1'a was most active in reducing the cell-free EBV DNA (EC(50)=1.38 μg/ml, therapeutic index>14.5). This study suggests that microalgae could be a potential source of antiviral compounds that can be used against EBV.
