Transcultural comparisons taking the differences and commonalities into consideration in the fields of mental health and ill mental health have always been a focus of scientific interest. The ‘East’ and ‘West’ comparisons in this regard, could be the one most widely deliberated. ‘East and West’, as a human-made conceptual construct, has evolved to signify many social, cultural, political, economic and psychological realities and meanings, beyond its geographical references. Such conceptualizations both reflect and re-construct our realities. -/- Beyond the inequalities and (...) discrepancies in resources, the ‘East and West’ dualism has an impact on mental health theory and praxis in a many different ways. The range, content, patterns and expression of psychopathology and psychiatric symptomatology; the explanatory models of mental disorders; the diagnostic and classification systems; the psychopharmacological and psychotherapeutical interventions; the role of family and psychosocial support systems; basic conceptualizations of mental health and disease are some of the main areas of diversity. -/- This chapter, after briefly discussing the historical roots of the conceptualization of ‘East and West’, will be focused on the relations of mental health and ill mental health with this and related conceptualizations. It is concluded that, in this day of globalization, to improve the quality of psychiatric theory and praxis within a framework of high ethical standards, a paradigm focusing on the unity in diversity and embracing a non-dualistic, non-categorical, and non-hierarchical humanistic approach to cultural differences would bring all the colours of humanity and therefore psychiatry onto the canvas.

We use an algebraic argument to prove that there are exactly two premaximal extensions of \’s consequence. We also show that one of these extensions is the minimal structurally complete extension of the unique maximal paraconsistent extension of \. Precisely, we show that there are exactly two covers of the variety of Boolean algebras in the lattice of quasivarieties of Sugihara algebras and that there is a unique minimal paraconsistent quasivariety in that lattice. We also obtain a corollary stating that (...) the set of paraconsistent extensions of \ forms a complete sublattice of the lattice of all \’s extensions. (shrink)

The article shows a simple way of calibrating the strength of the theory of positive induction, ${{\rm ID}^{*}_{1}}$ . Crucially the proof exploits the equivalence of ${\Sigma^{1}_{1}}$ dependent choice and ω-model reflection for ${\Pi^{1}_{2}}$ formulae over ACA 0. Unbeknown to the authors, D. Probst had already determined the proof-theoretic strength of ${{\rm ID}^{*}_{1}}$ in Probst, J Symb Log, 71, 721–746, 2006.

We prove that everyn-modal logic betweenKnandS5nis undecidable, whenever n ≥ 3. We also show that each of these logics is non-finitely axiomatizable, lacks the product finite model property, and there is no algorithm deciding whether a finite frame validates the logic. These results answer several questions of Gabbay and Shehtman. The proofs combine the modal logic technique of Yankov–Fine frame formulas with algebraic logic results of Halmos, Johnson and Monk, and give a reduction of the representation problem of finite relation (...) algebras.
