Little is known about challenges and transition that medical students from different cultural backgrounds face with regard to complementary medicine (CM). This paper explores such students’ experiences and perspectives of socio-cultural and academic difference with regard to CM and experiences of intercultural relations. Using a constructivist grounded theory approach, 30 in-depth qualitative interviews were conducted with medical students across 10 Australian medical schools. The data were rigorously analysed through a systematic process of coding, categorisation and theoretical development. The findings indicate that students adapted considerably to the host culture. Students with Western backgrounds integrated better socio-culturally and academically compared to students with non-Western backgrounds. Although nationality represented cultural identity, students’ construction of cultural difference was informed by their perception of diverging value systems within the specific educational environment. These values were, in turn, reflected in students’ reported behaviours, attitudes, and levels of engagement in socio-cultural and academic aspects of university life. Adaptation employed by students was evidenced largely due to their conflicting sense of responsibility towards familial culture regarding CM and focus on fitting in. While students’ tendency to gravitate towards cultural peers was evident, most students adapted to their host environment regarding CM to fit into normal intercultural encounters during medical school. In conclusion, students’ intercultural contact with regard to CM was both complex and problematic. At a time of significant diversification within the higher education student body, this paper highlights the role medical education institutions can play in fostering intercultural and academic guidance and support.  相似文献

为了解《山东医药》近6年刊载文章统计学方法的应用情况,并对存在的问题提出意见和建议,随机抽取《山东医药》2009-2014年发表的论文进行统计学方法系统分析.结果发现统计学错误最常见的是t检验代替方差分析、不注明所用的统计学方法和不具体写出统计值.认为医学论文作者要充分认识统计学的重要性,编辑部应加强统计学方法审查工作.  相似文献

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.  相似文献

Objectives

This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.

Method

Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.

Results

Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.

Conclusion

Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.  相似文献
