Engagement resources are linguistic resources of inter- subjective positioning,through which writers or speakers open up or close down dialogic space for putative reader and try to align or disalign readers on the ground of solidarity. This study applies engagement system to analyze political commentaries. It focuses on the denial resources in detail. In political commentaries, by using denial resources, the commentator invokes, and then directly rejects different opinions or beliefs the putative readers may have. Through strategy of dialogic resources, commentators try to make up for disalignments caused by denial and form the grounds for solidarity.展开更多

The publication date was limited to the period from January 1996 to June 2015. The search terms "headache", "headache disorders", "cephalalgia", "migraine", "tension-type headache", "practice guideline", "consensus ", "statement", "regulation", and "recommendation" were used in the "Me SH" and "Free-text" fields. The guidelines were independently appraised by four researchers using the Appraisal of Guidelines for Research and Evaluation Ⅱ instrument.RESULTS: A total of 23 guidelines published between 1998 and 2014 were reviewed. The overall consistency of the four appraisers was good [interclass correlation coefficient 0.84; 95% confidence interval(CI) 0.82-0.86]. The mean(standard deviation) scores for scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability, and editorial independence were 52.1(18.0), 39.5(17.1), 33.4(21.0), 49.8(21.9),23.8(19.3), and 24.2(23.7). Only two guidelines were recommended, 12 were recommended with modification, and nine were not recommended.CONCLUSION: Physical Traditional Chinese Medicine therapies were recommended to treat headache. The overall quality of headache guidelines was low in China, but evidence-based guidelines are gradually becoming mainstream. Guideline developers should carefully consider, in particular,three domains: rigor of development, applicability,and editorial independence.展开更多
