Tackling Teaching: Understanding Commonalities among Chemistry, Mathematics, and Physics Classroom Practices.

Abstract: Education research in chemistry, mathematics, and physics tends to focus on issues inherent to the discipline, most notably content. At this time, little literature evidence exists that documents fruitful collaborations between education specialists across the STEM disciplines. This work seeks to unite the disciplines by investigating a common task: teaching. This study explores how discipline-specific practices influence the common act of reformed teaching pedagogy with a focus on the use of inquiry. We seek to identify commonalities among classroom teaching practices in these disciplines and contribute to the development of analytical tools to study STEM teaching

Norwegian Women's experiences of 20th-century migration to England: Narratives of changing gender roles

This article discusses migratory gender roles within a north/north movement context. Using the case of older Norwegian women migrating to England while young, actively making migration part of their lives, it combines life course theory and migration theory about transnationalism, and presents three migratory life trajectory typologies. These are developed from life course interviews, based on class and gender role differences. One, upper-class based, is about transnational marriage as a key to leaving a small Norwegian community and becoming a ‘European’ housewife. Another, working-class based, is about using an au pair job as a stepping stone to migration and marriage, doing family-life-adapted paid work in Norwegian workplace ‘niches’. The third, middle-class based, is about using the migratory process for strengthening a professional identity. The article shows how a feeling of transnational ambiguity is exceeded the more the migratory gender role is about realising one’s own potentials, moving towards gender equality.publishedVersio

Trust and knowledge are two concepts that are considered important for understanding consumers’ engagement with organic products, but the concepts are often used at random. This article explores the configuration and generation of consumer trust in organics and investigates the relationship between knowledge and trust. The article is based on a multi-method study of Danish consumers’ perceptions of organics that included a consumer survey, a focus group, and individual interviews. The inquiry documents that Danish consumers’ display a high degree of trust in organics, and have overly positive expectations regarding organics, but know little about the difference between organic and non-organic products. Many respondents express no interest in acquiring additional knowledge, indicating that Danish consumers embody a blind trust of organics, but one that is also fragile because it might easily turn into distrust. Our results indicate that once consumers have decided to trust organics, they tend to seek confirmation of their belief and avoid conflicting knowledge that might challenge their decision. Our findings suggest that the general trust in organics is trumped by personal experiences and pragmatic concerns such as price, taste and appearance

Immunogenicity of HLA Class i and II double restricted influenza a-derived peptides

The aim of the present study was to identify influenza A-derived peptides which bind to both HLA class I and-II molecules and by immunization lead to both HLA class I and class II restricted immune responses. Eight influenza A-derived 9-11mer peptides with simultaneous binding to both HLA-A02:01 and HLA-DRB101:01 molecules were identified by bioinformatics and biochemical technology. Immunization of transgenic HLA-A02:01/HLADRB101:01 mice with four of these double binding peptides gave rise to both HLA class I and class II restricted responses by CD8 and CD4 T cells, respectively, whereas four of the double binding peptides did result in HLA-A02:01 restricted responses only. According to their cytokine profile, the CD4 T cell responses were of the Th2 type. In influenza infected mice, we were unable to detect natural processing in vivo of the double restricted peptides and in line with this, peptide vaccination did not decrease virus titres in the lungs of intranasally influenza challenged mice. Our data show that HLA class I and class II double binding peptides can be identified by bioinformatics and biochemical technology. By immunization, double binding peptides can give rise to both HLA class I and class I restricted responses, a quality which might be of potential interest for peptide-based vaccine development.Fil: Pedersen, Sara Ram.
