This paper is devoted to the study of some subvarieties of the variety Q of Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q subscript 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Q is far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q subscript 3 and we construct (...) the lattice of subvarieties lambda (Q subscript 3) of the variety Q subscript 3. (shrink)

The present work is motivated by recent experiments aimed to measure the propagation velocity of bound electromagnetic field that reveal no retardation in the absence of EM radiation. We show how these findings can be incorporated into the mathematical structure of special relativity theory that allows us to reconsider some selected problems of classical and quantum electrodynamics. In particular, we come to the conclusion that the total four-momentum for a classical system “particles plus fields” ought to be a present state (...) function of moving charges if EM radiation is negligible. In quantum domain, we analyze novel definition of the momentum operator recently suggested in the study of quantum phase effects. It implies that bound EM field energy and momentum are to be present state functions, too. Being in agreement with reported experiments, these conclusions suggest the necessity to carry out more precise experimental verifications for additional and independent determination of propagation properties of bound EM fields. A scheme of a possible experiment on this subject is also proposed. (shrink)

A Q -Heyting algebra is an algebra of type such that is a Heyting algebra and the unary operation ∇ satisfies the conditions ∇0=0, a ∧∇ a = a , ∇=∇ a ∧∇ b and ∇=∇ a ∨∇ b , for any a , b ∈ H . This paper is devoted to the study of the subvariety QH L of linear Q -Heyting algebras. Using Priestley duality we investigate the subdirectly irreducible linear Q -Heyting algebras and, as consequences, we (...) derive some properties of the lattice of subvarieties of QH L and find equational bases for some of these subvarieties.

En la ontología del Barroco hispano es supuesta una espectral despresencia de lo infinito en la finitud del mundo. A ella están vinculadas una erraticidad de lo humano y del mundo mismo. Esta errancia implica una comprensión trágica de la existencia. En el espacio contemporáneo, esta ontología reaparece como Transbarroco, inmanentizando el infinito. Una de sus expresiones fundamentales tiene lugar en el pensamiento de la diferencia de M. Heidegger (en el que es finalmente obstruida), así como en el de J. (...) Derrida y J.-L. Nancy, que radicalizan al primero y reabren lo transbarroco, aunque a costa de afirmar una errancia sin tragedia. (shrink)

Imagining Dewey' features productive (re)interpretations of 21st century experience using the lens of John Dewey's 'Art as Experience', through the doubled task of putting an array of international philosophers, educators, and artists-researchers in transactional dialogue and on equal footing in an academic text. This book is a pragmatic attempt to encourage application of aesthetic learning and living, ekphrasic interpretation, critical art and agonist pluralism.0There are two foci: (a) Deweyan philosophy and educational themes with (b) analysis and examples of how educators, (...) artists, and researchers envision and enact artful meaning making. This structure meets the needs of university and high school audiences, who are accustomed to learning about challenging ideas through multimedia and aesthetic experience.00Contributors are: James M. Albrecht, Adam I. Attwood, John Baldacchino, Carolyn L. Berenato, M. Cristina Di Gregori, Holly Fairbank, Jim Garrison, Amanda Gulla, Bethany Henning, Jessica Heybach, David L.

Aim: Patients with advanced cancer need information about end-of-life treatment options in order to make informed decisions. Clinicians vary in the frequency with which they initiate these discussions.Patients and methods: As part of a long-term longitudinal study, patients with an expected 2-year survival of less than 50% who had advanced gastrointestinal or lung cancer or amyotrophic lateral sclerosis were interviewed. Each patient’s medical record was reviewed at enrollment and at 3 months for evidence of the discussion of patient wishes concerning (...) ventilator support, artificial nutrition and hydration , resuscitation and hospice care. A Kaplan–Meier analysis was also performed and 2-year survival calculated.Results: 60 cancer and 32 ALS patients were enrolled. ALS patients were more likely than cancer patients to have evidence of discussion about their wishes for ventilator support , ANH , DNR and hospice care . At 6 months, 91% of ALS patients were alive compared with 62% of cancer patients; at 2 years, 63% of ALS patients were alive compared with 23% of cancer patients .Conclusions: Cancer patients were less likely than ALS patients to have had documented advanced care planning discussions despite worse survival. This may reflect perceptions that ALS has a more predictable course, that advanced cancer has a greater number of treatment options, or differing views about hope. Nevertheless, cancer patients may be less adequately prepared for end-of-life decision-making. (shrink)

I explore some of the ways that assumptions about the nature of substance shape metaphysical debates about the structure of Reality. Assumptions about the priority of substance play a role in an argument for monism, are embedded in certain pluralist metaphysical treatments of laws of nature, and are central to discussions of substantivalism and relationalism. I will then argue that we should reject such assumptions and collapse the categorical distinction between substance and property.

Causation is at once familiar and mysterious. Neither common sense nor extensive philosophical debate has led us to anything like agreement on the correct analysis of the concept of causation, or an account of the metaphysical nature of the causal relation. Causation: A User's Guide cuts a clear path through this confusing but vital landscape. L. A. Paul and Ned Hall guide the reader through the most important philosophical treatments of causation, negotiating the terrain by taking a set of examples (...) as landmarks. They clarify the central themes of the debate about causation, and cover questions about causation involving omissions or absences, preemption and other species of redundant causation, and the possibility that causation is not transitive. Along the way, Paul and Hall examine several contemporary proposals for analyzing the nature of causation and assess their merits and overall methodological cogency.The book is designed to be of value both to trained specialists and those coming to the problem of causation for the first time. It provides the reader with a broad and sophisticated view of the metaphysics of the causal relation. (shrink)

The project review as outlined in this article explores the questions: What is transformative research and what is transformation as far as the community stakeholders are concerned? To what extent has the transformative research achieved its intended outcomes? The Bokamoso project (founded by Lesego Serolong as facilitator and investor) is an integrated development project designed to create employment and to enable the community to learn while they make a living through a diverse range of farming activities. The participatory research as (...) discussed here is part of the University of South Africa’s research and community engagement programme, and is set in a remote, arid zone. This research coupled with community engagement aims to transform lives and create opportunities by enhancing their participation in education, training and employment creation. The project (which has been running since 2015) supports indigenous ways of being, knowing and doing and has succeeded in enabling the farmers trained through Bokamoso to be less dependent on social benefits (government grants).

A cross-sectional study to ascertain what the Singapore population would regard as material risk in the anaesthesia consent-taking process and identify demographic factors that predict patient preferences in medical decision-making to tailor a more patient-centered informed consent. A survey was performed involving patients 21 years old and above who attended the pre-operative evaluation clinic over a 1-month period in Singapore General Hospital. Questionnaires were administered to assess patients’ perception of material risks, by trained interviewers. Patients’ demographics were obtained. Mann–Whitney U (...) test and Kruskal-Wallis one-way analysis of variance was used. Statistical significance was taken at p < 0.05. Four hundred fourteen patients were eligible of which 26 refused to participate and 24 were excluded due to language barrier. 364 patients were recruited. A higher level of education, being employed and younger age group are factors identified in patients who wanted greater participation in medical decisions. Gender, marital status, type of surgery, and previous surgical history did not affect their level of participation. The complications most patients knew about were Nausea, Drowsiness and Surgical Wound Pain. Patients ranked Heart Attack, Death and Stroke as the most significant risks that they wanted to be informed about in greater detail. Most patients wanted to make a joint decision with the anaesthetist, instead of letting the doctor decide or deciding for themselves. Discussion with the anaesthetist is the preferred medium of communication compared to reading a pamphlet or watching a video. Age and educational level can influence medical decision-making. Despite the digital age, most patients still prefer a clinic consult instead of audio-visual multimedia for pre-operative anaesthetic counselling. The local population appears to place greater importance on rare but serious complications compared to common complications. This illustrates the need to contextualize information provided during informed consent to strengthen the doctor-patient relationship. (shrink)

Critical study of Sufism and Islamic philosophy with special reference of Ibn-i al-ʻArabī, 1165-1240.

We praise Arbib et al.'s Neural organization for its support of the integration of different levels of analysis, while noting that it does not always achieve what it advocates. We extend this approach into an area of neuropsychological activity in need of the structure offered by Organization at the intersection of the conflated fields of executive function and frontal lobe function.

It would be no exaggeration to say that our art is presently undergoing a revolutionary stage in its development. The revolutionary renewal that has seized all spheres of life is being ever more forcefully represented in artistic culture as well. That culture is beginning to free itself from bureaucratic regimentation, incompetent pressure from above, inflated authorities, lifeless cliches, and opportunism of the moment. Art is actively seeking its place in perestroika, and is in turn in many respects defining the moral (...) climate of perestroika. Recent works such as Fire [Pozhar] by V. Rasputin, the Sad Detective Story [Pechal'nyi detektiv] by V. Astaf'ev, The Execution Block [Plakha] by Ch. Aitmatov, the paintings of G. Korzhev and V. Sidorov, the sculpture of V. Klykov, etc., are actively working for renewal. (shrink)

In the 21stcentury, there is a turn of thinking toward its reorientation first of all to the human as an author of thought and not to the nature, existing independently of us and of the process of scientific knowledge obtaining. It is possible to see the difference of these two types of thinking in the context of dialogue between W. Whewell’s philosophy and the scientific investigations after the scientific revolution in the beginning of the 20thcentury. In the philosophy of 21stcentury, (...) man is a social being and this is the basis of social philosophy. The artificial world around us is created by a human, it has its foundation in the laws of thinking but not the laws of nature. The foundations of both systems are quite different. In what way can we achieve mutual understanding between them? From both sides some aspects can be put forward, for instance, the concept of a mediator of a thought. This concept is studied actively by W. Whewell and by philosophers of our time, and this leads in both cases to some unexpected interpretation of the basic question of philosophy: the border between thing and thought is becoming less noticeable. We can come to the same result, going by different ways. Whewell finds common qualities for some group of things. Social philosophers are interested in what makes things different. Not one of these idealizations corresponds completely to the reality. Always something is not taken into consideration. A thinker chooses out of real world some of its characteristics that become a basis of a thought system, which explains everything but in its own way. The paper demonstrates the way of possible creation of a new type of thinking. (shrink)
