What are the benefi ts of random allocation in clinical studies? John Worrall, a philosopher of science, recently questioned whether evidence-based medicine’s advice to base therapeutic decisions on the results of randomised controlled trials (RCTs) could be justifi ed.1 2 Here we provide a response to Worrall and others who challenge the epistemological value of RCTs. Worrall’s primary target ...

Awareness of the level of river flow and its fluctuations at different times is one of the significant factor to achieve sustainable development for water resource issues. Therefore, the present study two hybrid models, Wavelet- Adaptive Neural Fuzzy Interference System (WANFIS) and Wavelet- Artificial Neural Network (WANN) are used for flow prediction of Gamasyab River (Nahavand, Hamedan, Iran...

although public policy analysis is essential for public policy systems, the lack of public policy analysis is one of the most important problems of public policy making system in iran. thus, this research implemented to achieve a model for analyzing public policies, using multiple grounded theory method, to create theories and models compatible with the country`s conditions. for this purpose, p...
