To uncover how different backgrounds influence teacher beliefs,a multiple case study was done to three pre-service and three in-service EFL teachers through semi-structured interviews.The results show that pre-service and in-service teachers hold a general belief that while English exposure is important,the use of Chinese as the L1 is complementary.Nonetheless,teachers’rationale reflects influence from prior learning experience,teacher education and classroom practice.The findings provide implications for career development of EFL teachers. 展开更多

目的分析L型细菌感染与慢性结石性胆囊炎患者腹腔镜胆囊切除术(LC)术后手术部位感染(SSI)的关联性,为临床预防SSI提供干预措施。方法采用前瞻性巢式病例对照研究方法,收集2016年9月至2020年6月在贵州医科大学第三附属医院行LC的慢性结... 目的分析L型细菌感染与慢性结石性胆囊炎患者腹腔镜胆囊切除术(LC)术后手术部位感染(SSI)的关联性,为临床预防SSI提供干预措施。方法采用前瞻性巢式病例对照研究方法,收集2016年9月至2020年6月在贵州医科大学第三附属医院行LC的慢性结石性胆囊炎患者作为研究对象。术后随访观察时间为手术之日起1个月内,详细记录患者一般资料、围手术期情况、胆囊内容物L型细菌检出情况、术后SSI等指标,以及术者术前完成LC例数。根据术后是否发生SSI按照1∶4比例进行配对分组:SSI组和对照组。多因素logistic回归分析LC术后发生SSI的危险因素。结果共有695例患者被纳入研究,其中男性248例,女性447例,年龄(46.0±15.0)岁。SSI组(n=139)与对照组(n=556)L型细菌感染率分别为45.32%与30.94%,SSI组L型细菌感染率显著高于对照组(P<0.05)。L型细菌感染(OR=2.082,95%CI:1.335~3.197,P=0.001)、胆囊破裂(OR=2.249,95%CI:1.352~3.740,P=0.002)、胆囊及周围组织粘连(OR=1.903,95%CI:1.133~3.194,P=0.015)、术中出血量多(OR=2.247,95%CI:1.418~3.561,P=0.001)可增加慢性结石性胆囊炎患者LC术后发生SSI的风险,而术者术前完成LC例数多(OR=0.549,95%CI:0.340~0.888,P=0.014)可降低SSI风险。结论L型细菌感染是SSI的危险因素之一,加强慢性结石性胆囊炎患者L型细菌感染筛查,提高手术操作技能,重点注意胆囊及周围粘连患者的手术操作,减少术中出血量,避免胆囊破裂,可减少LC术后发生SSI的风险。 展开更多

It is driven by the need to improve English classroom instruction for university students in China (Wen, 2016). It is also motivated by the aspiration to enhance the quality of foreign language education in other similar pedagogical contexts outside China. A volume of research has been done by Wen Qiufang and her research team, to formulate the theory of POA and to test its effectiveness in classroom pedagogy (e.g. Wen, 2016, 2015; Yang, 2015; Zhang, 2015). At the moment, the POA is still at an early stage of theory building and almost all empirical research is done in the Chinese context. In order to improve the quality of this theory and to make it intelligible to the international academic community, a one-day symposium was held in Beijing Foreign Studies University on May 15, 2017. The symposium was entitled 'The first international forum on innovative foreign language education in China: Appraisal of the POA'. In the forum, leading experts in applied linguistics were invited to discuss the strengths and weaknesses of the POA and the directions for its future development. The symposium was the first attempt for the POA research team to discuss its latest work with international scholars. This Viewpoint section collects the responses of four experts who participated in the symposium, listed in alphabetical order. The collection of articles covers three topics related to the POA: its pedagogical application, its use for teacher training, and its research. Alister Cumming is Professor Emeritus and the former Head of the Centre for Educational Research on Languages and Literacies, University of Toronto, Canada. His article focuses primarily on POA research as an exemplary case of design-based research. Rod Ellis is Research Professor in the School of Education at Curtin University, Australia. He discusses POA in terms of pedagogy, teacher training and research, with both critiques and constructive suggestions. Paul Kei Matsuda is Professor of English and Director of Second Language Writing at Arizona State University, the writed states. He responds to POA from the perspective of an expert researcher and teacher of L2 writing. Charlene Polio is Professor and Associate Chair in the Department of Linguistics & Germanic, Slavic, Asian & African Languages atMichigan State University, the writed states. She conceptualises POA as a useful method to address some issues in pre-service teacher development. Overall, the articles in this section are insightful and reader-friendly. They are not only useful for the development of POA in particular, but may also be valuable to a broad range of researchers as they touch upon pertaining issues, as well as emerging topics, in the field of applied linguistics. We therefore find it necessary to make them accessible to a wide readership. 展开更多
