An interdisciplinary workshop was organized using a focus group format and the transcript of the discussion was interpreted by means of the qualitative content analysis. The most important research priorities for improving the care of depressed elderly persons, implementation levels, theoretical approaches as well as possible outcomes were analysed on individual consumer, healthcare system, and policy level. A wide range of theories and methods are necessary to identify and explain implementation processes and results. Qualitative and quantitative methodologies in combination with knowledge synthesis were discussed. In addition, the need to summarize the literature in terms of specific issues was emphasized. In conclusion, the implementation strategies for improving the care of depressed elderly persons should be addressed on three levels: individual consumer, healthcare system and policy. Although some aspects of the implementation model may need to be enhanced, the fact that it includes conditions on individual level, i.e. self-management support, is of importance. The expansion and maintenance of evidence-based care generate potential for change in mental healthcare, thus improving outcomes for individual elderly patients. Areas that require further research are organization, cost and leadership. The use of mixed methods could strengthen future studies. Implementation researchers need a broad repertoire in order to plan and perform evidence-based research. To improve practice, implementation strategies should be developed in clinical and community guidelines.展开更多

How to explore teaching characteristics and advantages of higher vocational education, and distinguish and complement teaching direction of traditional "academic" university is an urgent task of higher vocational college. Studio teaching construction has been accepted by more and more higher vocational colleges. However, there is not relatively mature running mode and teaching experience for the new thing. School of Arts and Design, Nanjing Vocational Institute of Industry Technology actively carries out the exploration and construction of "art workshop" teaching mode in recent years, which obtains better echo and recognition of society, teachers and students. It plays a leading role in research and exploration of studio teaching mode in higher vocational college, and could be taken as a typical case for analysis and summary.展开更多
