چکیده

The problem of aggregation processes in alignments is the subject of a paper published recently in a Statistical Physics Journal (Physica A230, 174-188, 1996). Two models are presented and discussed in that paper. First the energy landscape model proposed by Axelrod and Bennett (B. J. Pol. S. 23, 211-233, 1993), is analysed. The model is shown not to include most of its claimed results. Then a second model is presented to reformulate correctly the problem within statistical physics and to extend it beyond the initial Axelrod-Bennett analogy. ∗Laboratoire associé au CNRS (URA n◦ 800) et à l’Université P. et M.

The study of Health in All Policies (HiAP) is gaining momentum. Authors are increasingly turning to wide swathes of political and social theory to frame (Program) Theory Based (or Informed) Evaluation (TBE) approaches. TBE for HiAP is not only prudent, it adds a level of elegance and insight to the research toolbox. However, it is still necessary to organize theoretical thinking appropriately. ...

The article by Oortwijn, Jansen, and Baltussen (OJB) is much more important than it appears because, in the absence of any good general theory of “evidence-informed deliberative processes” (EDP) and limited evidence of how they might be shaped and work in institutionalising health technology assessment (HTA), the best approach seems to be to accumulate the experience of...

The re-conceptualization of knowledge translation (KT) in Kitson and colleagues’ manuscript “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation” is an advancement in how one can incorporate implementation into the KT process. Kitson notes that “the challenge is to explain how it might help in the healthcare policy, practice, and research communities.” We propose th...

ON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES

Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale ${0,1}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow to transfer the results from some particular class of extended Boolean functions, e.g., from c...
