Informal learning contexts in the construction of physical education student teachers' professional identity

This study aimed to investigate the significance of informal learning contexts in physical education (PE) student teachers’ professional identity construction. It addressed two research questions: How do informal learning contexts contribute to the construction of PE student teachers’ professional identity? What forms of relationships can be identified between the informal and formal contexts of learning in PE student teachers’ professional identity construction? The data consisted of 20 semi-structured interviews with PE student teachers during the final teaching practice period. The data were analysed using structural and pattern coding methods. The analysis revealed that informal learning contexts contributed to three elements of professional identity construction: professional ambitions, professional values and principles, and professional knowledge and competencies. Three distinct forms of relationships between informal and formal learning contexts in the construction of professional identity were also discovered: complementary, reconstructive and disconnected. Informal learning contexts appear highly influential in the construction of professional identity. The results also point towards a holistic notion of professional identity, where professional and personal aspects of identity merge and overlap in the construction of professional identity.publishedVersionPeer reviewe

A region on chicken chromosome 2 affects both egg white thinning and egg weight

We describe the results from genetic dissection of a QTL region on chicken chromosome 2, shown to affect egg weight and quality in an earlier genome scan of an F2 intercross between two divergent egg layer lines. As the 90% confidence intervals for the detected QTL covered tens of centiMorgans, new analyses were needed. The datasets were reanalysed with denser marker intervals to characterise the QTL region. Analysis of a candidate gene from the original QTL region, vimentin, did not support its role in controlling egg white thinning. Even after reanalysis with additional seven markers in the QTL area, the 90% confidence intervals remained large or even increased, suggesting the presence of multiple linked QTL for the traits. A grid search fitting two QTL on chromosome 2 for each trait suggested that there are two distinct QTL areas affecting egg white thinning in both production periods and egg weight in the late production period. The results indicate possible pleiotropic effects of some of the QTL on egg quality and egg weight. However, it was not possible to make a distinction between close linkage versus pleiotropic effects

Professional identity among student teachers of physical education : the role of physicality

In this study, we investigate the role of physicality in the professional identities of physical education (PE) student teachers. Twenty PE student teachers participated in semi-structured interviews during their final teaching practice. Data were analysed using qualitative thematic analysis (Braun and Clarke 2006) and typologies (Patton 2002). The results showed substantial diversity in the student teachers’ conceptions of physicality and the ways these conceptions were embedded in their developing professional identities. The results also brought to light criticism directed at traditional notions of the body and physicality in PE and PE teacher education (PETE). We suggest that conceptions of the body and physicality represent a central element of PE teachers’ professional identity. The results also indicate a relationship between conceptions of physicality and pedagogies implemented in the future. Time and place for student teachers to discuss body-related matters should be provided in PETE.peerReviewe

Genes and pathways revealed by whole transcriptome analysis of milk derived bovine mammary epithelial cells after Escherichia coli challenge

Abstract Mastitis, inflammation of the mammary gland, is the costliest disease in dairy cattle and a major animal welfare concern. Mastitis is usually caused by bacteria, of which staphylococci, streptococci and Escherichia coli are most frequently isolated from bovine mastitis. Bacteria activate the mammary immune system in variable ways, thereby influencing the severity of the disease. Escherichia coli is a common cause of mastitis in cattle causing both subclinical and clinical mastitis. Understanding of the molecular mechanisms that activate and regulate the host response would be central to effective prevention of mastitis and breeding of cows more resistant to mastitis. We used primary bovine mammary epithelial cell cultures extracted noninvasively from bovine milk samples to monitor the cellular responses to Escherichia coli challenge. Differences in gene expression between control and challenged cells were studied by total RNA-sequencing at two time points post-challenge. In total, 150 and 440 (Padj < 0.05) differentially expressed genes were identified at 3 h and 24 h post-challenge, respectively. The differentially expressed genes were mostly upregulated at 3 h (141/150) and 24 h (424/440) post-challenge. Our results are in line with known effects of E. coli infection, with a strong early inflammatory response mediated by pathogen receptor families. Among the most significantly enriched early KEGG pathways were the TNF signalling pathway, the cytokine-cytokine receptor interaction, and the NF-kappa B signalling pathway. At 24 h post-challenge, most significantly enriched were the Influenza A, the NOD-like receptor signalling, and the IL-17 signaling pathway
