It is shown that in a linearly ordered MV-algebra A , the implication is unique if and only if the identity function is the unique De Morgan automorphism on A . Modulo categorical equivalence, our uniqueness criterion recalls Ohkuma's rigidness condition for totally ordered abelian groups. We also show that, if A is an Archimedean totally ordered MV-algebra, then each non-trivial De Morgan automorphism of the underlying involutive lattice of A yields a new implication on A , which is not (...) isomorphic to the original implication.

It seems that the choice for the subject "Christian Ethics in Ukrainian Culture" was made by everyone: the so-called "traditional Churches" and the authorities. The move, however, leaves much room for thought. First, who will teach this subject in educational institutions? We propose to use the experience not only of the western regions of Ukraine, including Lviv, Ivano-Frankivsk, etc., but also of the Ostroh Academy National University. When on March 24, 2000, the Rivne Regional Council decided to introduce the subject (...) of Christian ethics in Rivne schools, the National University "Ostroh Academy" became one of the basic training centers for teachers of Christian ethics. The creation of a faculty for the training of teachers of Christian ethics caused, accordingly, the recruitment of students. (shrink)
Wal-Mart received widespread praise for its response to Hurricane Katrina when it hit the Louisiana coast in August 2005 and low prices at the world’s largest retailer are estimated to save consumers billions of dollars a year. Nonetheless, it was coming under increasing criticism for corebusiness practices, ranging from detrimental effects on communities when Wal-Mart stores are established, to abusive labour practices, to alleged sourcing from sweatshops. This case looks at the benefits and the potentially harmful consequences of the Wal-Mart (...) business model. The focus is on supply chain issues and, more specifically, a lawsuit brought by the International Labor Rights Fund charging that Wal-Mart failed to meet contractual obligations specified in its Standards for Suppliers Agreement. However, the retailer must respond to a range of criticisms that chief executive Lee Scott recognizes are harming its reputation. Scott asks, in reference to Wal-Mart’s response to Katrina, “what would it take for Wal-Mart to be that company, at our best, all the time?” More fundamentally, the case asks, how sustainable is Wal-Mart’s business model?

The geometric system of deduction called N-Graphs was introduced by de Oliveira in 2001. The proofs in this system are represented by means of digraphs and, while its derivations are mostly based on Gentzen's sequent calculus, the system gets its inspiration from geometrically based systems, such as the Kneales' tables of development, Statman's proofs-as-graphs, Buss' logical flow graphs, and Girard's proof-nets. Given that all these geometric systems appeal to the classical symmetry between premises and conclusions, providing an intuitionistic version of (...) any of these is an interesting exercise in extending the range of applicability of the geometric system in question. In this article we produce an intuitionistic version of N-Graphs, based on Maehara's LJ' system, as described by Takeuti. Recall that LJ' has multiple conclusions in all but the essential intuitionistic rules, e.g., implication right and negation right. We show soundness and completeness of our intuitionistic N-Graphs with respect to LJ'. We also discuss how we expect to extend this work to a version of N-Graphs corresponding to the intuitionistic logic system FIL (Full Intuitionistic Logic) of de Paiva and Pereira and sketch future developments.

"In the aftermath of New Historicism and Cultural Materialism, the field of Shakespeare Studies has been increasingly overrun by post-theoretical, phenomenological claims. Many of the critical tendencies that hold the field today--post-humanism, speculative realism, ecocriticism, historical phenomenology, new materialism, performance studies, animal studies, affect studies--are consciously or unwittingly informed by phenomenological assumptions. This book aims at uncovering and examining these claims, not only to assess their philosophical congruency but also to determine their hermeneutic relevance when applied to Shakespeare. More specifically, (...) Unphenomenal Shakespeare deploys resources of speculative critique to resist the moralistic and aestheticist phenomenalization of the Shakespeare playtexts across a variety of schools and scholars, a tendency best epitomized in Bruce Smith's Phenomenal Shakespeare "--.

The present research aims to explore and describe the opinion of primary education teachers about performance evaluation. It is applied in the State of Tlaxcala, Mexico. The focus of the study is quantitative, since a questionnaire is applied based on a Likert scale, the data are analyzed with the program Statistical Package for Social Sciences. The results show that the study population is mostly at odds with the evaluation.
This anthology provides the definitive theoretical sources of contemporary thinking about identity, including explorations of race, class, gender, and nationality. Explores the long and rich tradition of philosophical analysis and debate over the genesis, contours, and political effects of identity categories. Provides the definitive theoretical sources and contemporary debates by leading theorists such as selections from Hegel, Marx, Freud, DuBois, Beauvoir, Lukács, Fanon, Hall, Guha, Hobsbawm, Wittig, Butler, Halperin, R. Robertson, Said, and LaClau. Combines general and specific analyses of particular (...) identity categories: race/ethnicity, gender/sexuality, class, nationality. Allows for a comparative study of identities through multiple theoretical frameworks. (shrink)

In this paper we shall introduce the variety FWHA of frontal weak Heyting algebras as a generalization of the frontal Heyting algebras introduced by Leo Esakia in . A frontal operator in a weak Heyting algebra A is an expansive operator r preserving finite meets which also satisfies the equation?? b V, for all a,b? A. These operators were studied from an algebraic, logical and topological point of view by Leo Esakia in . We will study frontal operators in weak (...) Heyting algebras and we will consider two examples of them. We will give a Priestley duality for the category of frontal weak Heyting algebras in terms of relational spaces where is a WH space , and R is an additional binary relation used to interpret the modal operator. We will also study the WH- algebras with successor and the WTf- algebras with gamma. For these varieties we will give two topological dualities. The first one is based on the representation given for the frontal weak Heyting algebras. The second one is based on certain particular classes of WH-spaces. (shrink)

Strong evidence shows that exposure and engagement with the natural world not only improve human wellbeing but can also help promote environmentally friendly behaviors. Human-nature relationships are at the heart of global agendas promoted by international organizations including the World Health Organization’s “One Health” and the United Nations “Ocean Decade.” These agendas demand collaborative multisector interdisciplinary efforts at local, national, and global levels. However, while global agendas highlight global goals for a sustainable world, developing science that directly addresses these agendas (...) from design through to delivery and outputs does not come without its challenges. In this article, we present the outcomes of international meetings between researchers, stakeholders, and policymakers from the United Kingdom and Brazil. We propose a model for interdisciplinary work under such global agendas, particularly the interface between One Health and the UN Ocean Decade and identify three priority research areas closely linked to each other: human-nature connection, conservation-human behavior, and implementation strategies. We also discuss a number of recommendations for moving forward. (shrink)
David E. Over is a leading cognitive scientist and, with his firm grounding in philosophical logic, he also exerts a powerful influence on the psychology of reasoning. He is responsible for not only a large body of empirical work and accompanying theory, but for advancing a major shift in thinking about reasoning, commonly known as the ‘new paradigm’ in the psychology of human reasoning. -/- Over’s signature mix of philosophical logic and experimental psychology has inspired generations of researchers, psychologists, and (...) philosophers alike over more than a quarter of a century. The chapters in this volume, written by a leading group of contributors including a number who helped shape the psychology of reasoning as we know it today, each take their starting point from the key themes of Over’s ground-breaking work. The essays in this collection explore a wide range of central topics—such as rationality, bias, dual processes, and dual systems—as well as contemporary psychological and philosophical theories of conditionals. It concludes with an engaging new chapter, authored by David E. Over himself, which details and analyses the new paradigm psychology of reasoning. -/- This book is therefore important reading for scholars, researchers, and advanced students in psychology, philosophy, and the cognitive sciences, including those who are not familiar with Over’s thought already.
