In this paper we build upon previous works of Hájek and Vychodil on the axiomatization of truthstressing and depressing hedges as expansions of BL logic by new unary connectives. They show that their logics are chain-complete, but standard completeness is only proved for the expansions over Gödel logic. We propose weaker axiomatizations that have as main advantages the preservation of standard ...

Slowly but surely, intuitionistic fuzzy sets are giving away their secrets. By tracing them back to the underlying algebraic structure that they are defined on (a complete lattice), they can be embedded in the well– known class of L–fuzzy sets, whose formal treatment allows the definition and study of order–theoretic concepts such as triangular norms and conorms, negators and implicators, as we...

In recent years, Serratia marcescens has become established in certain localities as an agent of hospital infection and cross-infection (Clayton & von Graevenitz, 1966; Wilfert, Barrett & Kass, 1968; Davis, Foltz & Blakemore, 1970; Wilkowske, Washington, Martin & Ritts, 1970). In general, strains of S. marcescens isolated from infective lesions differ from those from other sources in being non-...

OBJECTIVE The use of mindfulness-based therapy (MBT) in oncology settings has become increasingly popular, and research in the field has rapidly expanded. The objective was by means of a systematic review and meta-analysis to evaluate the current evidence for the effect of MBT on symptoms of anxiety and depression in adult cancer patients and survivors. METHOD Electronic databases were search...

evidence occupies a paramount position in any logical endeavor and research article is consensually considered a predominant site of such an endeavor. one interesting area of rhetoric which addresses the source and reliability of evidence is quality metadiscourse. in this qualitative study, quality metadiscourse strategies (i.e., evidentials, hedges, boosters and disclaimers) are examined to in...
