ABSTRACTIn recent decades, the work of teachers worldwide has undergone deep change. We have seen that teachers have encountered recent challenges differently and adapted to educational changes to a different extent depending on their personal disposition, but also school leadership and workplace support. This study focuses on the example of Estonian vocational teachers that serves as an interesting case for analysing how the interplay of the transitional context and neo-liberal policy trends adopted since Estonia regained its independence in 1991, after 50 years under Soviet rule, have affected the individual trajectories of teachers’ lives. This paper aims to understand how the interplay of the institutional context and individual (work) lives shapes Estonian vocational teachers’ understandings of their work and professionality. We suggest that certain periods of practice are visible in teachers’ narratives and those periods might be considered as enabling different degrees of agency. However, our interviews also revealed that different reform periods have been perceived and responded to differently. In the context of 25 years of the educational reform process, the policies and requirements introduced have been refracted at different levels (Goodson & Rudd, 2017), including that of the vocational field, the schools and individual teachers. Our results confirm that teachers individual, social, cultural and material resources such as competence, career stage, relations and networks, school leadership and prevailing culture at schools have their role in enabling or hindering the agency of teachers. 相似文献

Bio-electrosprays (BESs) provide a means of precisely manipulating cells and thus have the potential for many clinical uses such as the generation of artificial tissues∕organs. Previously we tested the biological safety of this technology with a variety of living cells and also embryos from the vertebrate model organisms Danio rerio (zebrafish) and Xenopus tropicalis (frog). However, the viability and fertility of the treated embryos could not be fully assessed due to animal licensing laws. Here we assay the viability and fertility of Drosophila melanogaster (fruit fly) embryos in conjunction with the bio-electrospray procedure. Bio-electrosprayed Drosophila embryos developed into fully fertile adult flies that were indistinguishable from wild-type. Thus, we demonstrate that the bio-electrospray procedure does not induce genetic or physical damage that significantly affects the development or fertility of a multicellular organism. This study along with our previous investigations demonstrates the potential of this approach to be developed for the precise manipulation of sensitive biological materials. 相似文献

Findings are presented on a U.K. study of 41 gay father families, 40 lesbian mother families, and 49 heterosexual parent families with an adopted child aged 3–9 years. Standardized interview and observational and questionnaire measures of parental well‐being, quality of parent–child relationships, child adjustment, and child sex‐typed behavior were administered to parents, children, and teachers. The findings indicated more positive parental well‐being and parenting in gay father families compared to heterosexual parent families. Child externalizing problems were greater among children in heterosexual families. Family process variables, particularly parenting stress, rather than family type were found to be predictive of child externalizing problems. The findings contribute to theoretical understanding of the role of parental gender and parental sexual orientation in child development. 相似文献
