A Critique of Authenticity and Recognition

While forms of ethics based upon authenticity and recognition are holding sway in contemporary philosophical debates (Ferrara, Honneth, Fraser, etc.), many of the implications of both processes – conceptual, moral, political – are still insufficiently reflected upon. The talk will offer a “critique” (in the Kantian sense) of both, based upon an analysis of the “semiotics” of authenticity and the resulting perpetuation of a regime of authority of experts, as well as commenting upon the striking absence of the realm of literature and the arts from this debate, except in some references to a rather abstract notion of Aesthetics. It will also critically revaluate the concept of agency implicit in an ethics of authenticity and recognition.

The evidence from systematic reviews and meta-analyses published in orthodontic literature. Where do we stand?

AIM To analyse meta-analyses included in systematic reviews (SRs) published in leading orthodontic journals and the Cochrane Database of Systematic Reviews (CDSR) focusing on orthodontic literature and to assess the quality of the existing evidence. MATERIALS AND METHODS Electronic searching was undertaken to identify SRs published in five major orthodontic journals and the CDSR between January 2000 and June 2014. Quality assessment of the overall body of evidence from meta-analyses was conducted using the Grading of Recommendations Assessment, Development and Evaluation working group (GRADE) tool. RESULTS One hundred and fifty-seven SRs were identified; meta-analysis was present in 43 of these (27.4 per cent). The highest proportion of SRs that included a meta-analysis was found in Orthodontics and Craniofacial Research (6/13; 46.1 per cent), followed by the CDSR (12/33; 36.4 per cent) and the American Journal of Orthodontics and Dentofacial Orthopaedics (15/44; 34.1 per cent). Class II treatment was the most commonly addressed topic within SRs in orthodontics (n = 18/157; 11.5 per cent). The number of trials combined to produce a summary estimate was small for most meta-analyses with a median of 4 (range: 2-52). Only 21 per cent (n = 9) of included meta-analyses were considered to have a high/moderate quality of evidence according to GRADE, while the majority were of low or very low quality (n = 34; 79.0 per cent). CONCLUSIONS Overall, approximately one quarter of orthodontic SRs included quantitative synthesis, with a median of four trials per meta-analysis. The overall quality of evidence from the selected orthodontic SRs was predominantly low to very low indicating the relative lack of high quality of evidence from SRs to inform clinical practice guidelines.
