Health and welfare practitioners in the United Kingdom have experienced and continue to experience considerable turbulence as services and occupational boundaries undergo restructuring. To a significant extent such turbulence is driven by policies that promote interprofessional agendas. This paper reports on an evaluation of a higher education programme that adopted a social policy approach to the analysis of interprofessional working. The retrospective views were sought of nursing, midwifery, social work and community and youth work post-qualifying students with use of semi-structured questionnaires and focus groups. Although difficulties were encountered with the political science focus to the programme, overall the participants very positively evaluated the opportunity to engage in policy analysis in a shared learning environment. Given the highly politicised, complex and shifting environment of interprofessional working, it is suggested that the study lends support to the argument that 'policy acumen' is a central skill for contemporary health and welfare practitioners. The paper, therefore, starts to explore issues of particular relevance for educationalists involved in developing frameworks for interprofessional programmes particularly in higher education. 相似文献

Simulation offers an opportunity for realistic assessment of nurse competency. Designing a simulation competency testing process for a specialty setting such as radiology requires careful thought regarding purposes of assessment and fair uses of assessment for further learning or personnel decisions. Development of an assessment process includes identifying objectives, creating a scenario, choosing the type of simulation strategy, validating the scenario, implementing the process, and evaluating the outcomes. 相似文献

Alanine substitutions and selected deletions have been used to localize amino acids in QnrB essential for its protective activity. Essential amino acids are found at positions i and i−2 in the pentapeptide repeat module and in the larger of two loops, where deletion of only a single amino acid compromises activity. Deletion of 10 amino acids at the N terminus is tolerated, but removal of 3 amino acids in the C-terminal dimerization unit destroys activity. 相似文献
