By weakening an inference rule satisfied by logic daC, we define a new paraconsistent logic, which is weaker than logic \ and G′ 3, enjoys properties presented in daC like the substitution theorem, and possesses a strong negation which makes it suitable to express intutionism. Besides, daC ' helps to understand the relationships among other logics, in particular daC, \ and PH1.

In the Eudemian Ethics Aristotle states that human beings are starting points of things that could be otherwise and that the eph’hemin are this kind of things. Famously, in the Nicomachean Ethics Aristotle endorses the thesis of habits’ unidirectionality, according to which the agent who already possesses moral habits, hexeis, will perform only actions consistent with the habits she possesses. Despite this apparent inconsistency, I aim to show that the two texts can be harmonized and that the Eudemian Ethics can (...) actually provide a theoretical background for habits’ unidirectionality.

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

Recently, Brass and Dix showed 143–165) that the well founded semantics WFS can be defined as a confluent calculus of transformation rules. This led not only to a simple extension to disjunctive programs 167–213), but also to a new computation of the well-founded semantics which is linear for a broad class of programs. We take this approach as a starting point and generalize it considerably by developing a general theory of Confluent LP-systems CS . Such a system CS is a (...) rewriting system on the set of all logic programs over a fixed signature L and it induces in a natural way a canonical semantics. Moreover, we show four important applications of this theory: most of the well-known semantics are induced by confluent LP-systems , there are many more transformation rules that lead to confluent LP-systems , semantics induced by such systems can be used to model aggregation , the new systems can be used to construct interesting counterexamples to some conjectures about the space of well-behaved semantics.

Nel 1589 Hercole Filogenio scrisse un discorso che intitolò _Dell’eccellenza della donna_, con l’intento di allinearsi “all’opinione di coloro che si sforzano scoprire l’errore di molti, quali tanto si affannano in avilire il feminil sesso” e dedicò il suo scritto a Flavia Peretti Orsina, donna distinta e dallo spirito inquieto, che con i suoi interessi contribuì allo sviluppo della società dell’epoca. Nel suo tentativo di preservare le donne dal biasimo manifestato dal maschilismo egemone e, allo stesso tempo, elogiare le loro (...) virtù, Filogenio propone due conclusioni, l’analisi e l’approfondimento delle quali, per mezzo di un’argomentazione valida, costituiscono il nucleo testuale della sua opera. L’articolo presenta e analizza i ragionamenti che Filogenio sviluppa nella seconda parte del suo discorso sui quali intende imperniare la dimostrazione della seconda conclusione: che la Donna non è superiore né inferiore all’Uomo, ma simile e uguale per nobiltà, eccellenza e perfezione.

ObjectivesThe aims of this research were to compare the levels of physical activity of eHealth users and non-users, to determine the effects of these technologies on motivations, and to establish the relationship that could exist between psychological constructs and physical activity behaviors.MethodsThis cross-sectional study involved 569 adults who responded to an online questionnaire during confinement in France. The questions assessed demographics, usage of eHealth for exercise and physical activity, and behavioral levels. The questionnaire also measured the constructs of Social Cognitive (...) Theory, the Theory of Planned Behavior, and automaticity facets toward eHealth for exercise and physical activity.ResultsParticipants who were users of eHealth for exercise and physical activity presented significantly higher levels of vigorous physical activity and total physical activity per week than non-users. The chi-square test showed significant interactions between psychological constructs toward eHealth and physical activity levels. Self-efficacy was significantly and negatively correlated with walking time per week. Concerning the automaticity facets, efficiency was positive and significantly correlated with vigorous physical activity levels per week. Then, regressions analyses showed that self-efficacy and automaticity efficiency explained 5% of the variance of walking minutes per week and vigorous physical activity per week, respectively.ConclusionThis study has shown that people during confinement looked for ways to stay active through eHealth. However, we must put any technological solution into perspective. The eHealth offers possibilities to stay active, however its benefits and the psychological mechanisms affected by it remains to be demonstrated: eHealth could be adapted to each person and context.

We show that arbitrary tautologies of Johansson’s minimal propositional logic are provable by “small” polynomial-size dag-like natural deductions in Prawitz’s system for minimal propositional logic. These “small” deductions arise from standard “large” tree-like inputs by horizontal dag-like compression that is obtained by merging distinct nodes labeled with identical formulas occurring in horizontal sections of deductions involved. The underlying geometric idea: if the height, h(∂), and the total number of distinct formulas, ϕ(∂), of a given tree-like deduction ∂ of a minimal (...) tautology ρ are both polynomial in the length of ρ, |ρ|, then the size of the horizontal dag-like compression ∂ᶜ is at most h(∂)×ϕ(∂), and hence polynomial in |ρ|. That minimal tautologies ρ are provable by tree-like natural deductions ∂ with |ρ|-polynomial h(∂) and ϕ(∂) follows via embedding from Hudelmaier’s result that there are analogous sequent calculus deductions of sequent ⇒ρ. The notion of dag-like provability involved is more sophisticated than Prawitz’s tree-like one and its complexity is not clear yet. Our approach nevertheless provides a convergent sequence of NP lower approximations of PSPACE-complete validity of minimal logic. (shrink)

This paper proposes a reconciliation between libertarian freedomand causal indeterminism, without relying on agent-causation asa primitive notion. I closely examine Peter van Inwagen's recentcase for free will mysterianism, which is based in part on thewidespread worry that undetermined acts are too chancy to befree. I distinguish three senses of the term ‘chance’ I thenargue that van Inwagen's case for free will mystrianism fails,since there is no single construal of the term ‘change’ on whichall of the premises of his argument for (...) free will–causalindeterminism incompatibilism are true. By use of a particularevent-causal indeterminist account of free action, I support thecase for free will–indeterminism compatibilism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Theology of Play and the Play of Theology in Thomas AquinasDavid L. Whidden IIISTUDENTS OF THOMAS AQUINAS have argued over many issues in the last 150 years or so; in fact, it is nearly impossible to get out of the very first question of the Summa Theologiae without entering into a century-long debate about the status of sacred doctrine as an Aristotelian science. We ponder whether theology meets (...) the requirements of a scientia and argue about just how to understand the task of theology in the face of Aquinas’s concern about theology as a scientia. Part of this ongoing argument is shaped by the philosophical and epistemological needs of theologians attempting to justify their positions in an academic world driven by the secular and scientific norms of the Enlightenment. Additionally, some interest in theology as a scientia is driven by the desire to provide a philosophically acceptable alternative to secular forms of reason—thus Leo’s XIII’s promotion of Thomistic philosophy.The interest in theology as a science was shaped by the historical work of Chenu in his influential articles on the topic and then by almost every other important Thomist in the last fifty years.1 Theology as a scientia is such a pressing topic that it would almost be fair to say that Thomists have developed their own scientia of theology as a scientia. [End Page 273]Beyond the modern and, perhaps, postmodern concerns driving this interest, there are good reasons to pay attention to Aquinas on the status of theology. If we focus on theology as a scientia, it is because Aquinas invites us to do so by taking up this question in one form or another at the beginning of his major theological syntheses. We are, after all, only following his lead and pondering with him just what we are thinking about, and how we are thinking, when we think about God.Within the Thomistic corpus there is, however, a minority report with regard to the status of theology. In his prologue to his commentary on Boethius’s Hebdomads, Aquinas looks at theology in a very different way, one that can supplement our understanding of sacred doctrine in its role as both an intellectual and an affective enterprise. In this commentary Aquinas journeys into a different territory and explores theology, not as a scientia, but as a kind of play—a play that evokes delight and pleasure in the one who pursues wisdom.My approach will be first to describe Aquinas’s theology with regard to regular play—the kind of recreational activities we all engage in, whether they are physical or verbal. He takes up the question of the morality of play in several places and in a way that will inform our understanding of what he means when he describes theology as play. With this understanding of regular play in place, we will then explore theology as play, based on the supposition that there is something analogical between regular play and theology as play. I will finish with some reflections on how this might contribute to our present understanding of theological work.IWhile he scatters comments about play across his corpus and mentions it in all of his theological syntheses, Aquinas gives sustained attention to play in two places: first, in his commentary on Aristotle’s Ethics, and second, in question 168 of the Secunda secundae (in the treatise on temperance) of the Summa theologiae. From the outset one will notice that one of [End Page 274] the difficulties in thinking about play with Aquinas is that the Latin word for play, ludo, is multivalent, difficult to translate, and so can sometimes mean recreational games, sometimes word play, and sometimes making fun of or deriding someone.2 Even the context does not always make it clear exactly how Aquinas is talking about play.In these two sustained treatments of play Aquinas is concerned with two main issues: first, the purpose of play; second, the morality of games and how they can be approached virtuously—with proper order. That is, he is concerned with the why and the how of games.Aquinas pursues these issues in his commentary... (shrink)

Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)

We have arrived at an inflection point, a moment in history when the sentience, conscious- ness, intelligence, agency, and even the moral agency of many nonhuman animals can no longer be questioned without ignoring centuries of accumulated scientific knowledge. Nowhere is this more true than in our understanding of nonhuman primates (NHPs). A neu- roethics committed to probing the ethical implications of brain research must be able to respond to and anticipate the challenges ahead as brain projects globally prepare to (...) increase the use of NHPs in research. This requires adopting a less anthropocentric focus that includes nonhuman animals within its scope. But the Neuroethics Roadmap represents a missed opportunity to critically examine the future direction of research with NHPs in an ethically-responsive neuroscience. (shrink)

Our interpretive resources enable us to make sense of, navigate, and communicate about our shared world. These resources not only carve the world up into categories, but also guide how we, individually and collectively, are oriented towards it. In this thesis, I examine how these resources, and the dispositions they guide, may be harmful. A vital kind of interpretive resources are frames, which equip us with unified perspectives on the world. Perspectives are suites of open-ended interpretive (inquisitive, attentional, inferential, evaluative, (...) and affective) dispositions. Frames thereby guide how we interpret, respond to, and navigate the world. I show that these perspectives are epistemically powerful and indispensable. I argue that flawed perspectives, and the distorting frames that produce them, are deeply pernicious and I examine their relationship to oppression. (shrink)

Organ donation after the circulatory determination of death requires the permanent cessation of circulation while organ donation after the brain determination of death requires the irreversible cessation of brain functions. The unified brain-based determination of death connects the brain and circulatory death criteria for circulatory death determination in organ donation as follows: permanent cessation of systemic circulation causes permanent cessation of brain circulation which causes permanent cessation of brain perfusion which causes permanent cessation of brain function. The relevant circulation that (...) must cease in circulatory death determination is that to the brain. Eliminating brain circulation from the donor ECMO organ perfusion circuit in thoracoabdominal NRP protocols satisfies the unified brain-based determination of death but only if the complete cessation of brain circulation can be proved. Despite its medical and physiologic rationale, the unified brain-based determination of death remains inconsistent with the Uniform Determination of Death Act. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS Metaphysics as a Guide to Morals. By IRIS MURDOCH. Harmondsworth: Allen Lane; New York: Viking, 1992. $35.00. Dame Iris Murdoch is familiar to most people as a witty and en· gaging novelist whose twenty-four hooks of fiction can he read on a variety of levels. They are wonderful stories, hut the philosophically acute reader will also enjoy Murdoch's judgments, polemics, and inhouse jokes about philosophers and philosophical (...) views. Comparatively few people are aware of Murdoch's previous scholarly studies: Sartre, Romantic Rationalist, The Sovereignty of the Good, The Fire and the Sun; and Acastos. Even so, those familiar with these hooks will recognize the profound impact she has had on debates within moral philosophy. She has been at the forefront of the move· ment that has rehabilitated the central importance of such notions as goodness, the Good, virtue, and the moral life as a journey. So it is not surprising that Murdoch has returned to the genre of philosophical argument to advance her views on the relationship between metaphysics and morals. But it is surprising that her argument exhibits neither the clarity of thought characteristic of the analytic philosophy in which she was trained nor the dramatic narrative of her novels. Indeed the hook reads like a collage of lecture notes, complete with extensive quotations from other people's thoughts with minimal com· mentary. Further, the chapter titles (e.g., " Fact and Value," " Schopenhauer," " Consciousness and Thought-I," " Derrida and Struc· turalism," " Consciousness and Thought-II," "Notes on Will and Duty," " Axioms, Duties, Eros," " Void ") shed little light on the overall structure or argument of the hook. One cannot help hut have the impression that Murdoch spent less time crafting the argument of this hook than she does in crafting the story line and characters of her novels. This is not to say, of course, that there is not much to he learned from Murdoch's perspective. She is remarkably erudite, and her discussion of various themes, figures, and issues often yields fascinating insights. But the whole is considerably less than the sum of its often interesting parts. I have already suggested that this is partly because of the structure and style in which the hook is written. But the hook 687 688 BOOK REVIEWS is also disappointing, and perhaps more determinatively, because of the overall perspective she seeks to deploy and defend. Readers of Murdoch's work have heretofore often wondered about the relationship between her avowed Platonism and her interest in Christianity. Metaphysics as a Guide to Morals has the virtue of clarifying that relationship, hut the result is unpersuasive. At the heart of Murdoch's Platonism is her recasting of the allegory of the cave from The Republic. The moral life is an arduous struggle to ascend from the cave (represented, as in her earlier works, by " the fat, relentless ego ") by a dispossession of the self so that we can apprehend a little less imperfectly the perfect form of the Good. As Murdoch puts it, Plato assumes the internal relation of value, truth, cogmtion. Virtue (as compassion, humility, courage) involves a desire for and achievement of truth instead of falsehood, reality instead of appearance. Goodness involves truth.seeking knowledge and ipso facto a discipline of desire. ' Getting things right ', as in meticulous grammar or mathematics, is truth-seeking as virtue. Learning anything properly demands (virtuous ) attention. Here the idea of truth plays a crucial role (as it does also in Kant) and reality emerges as the object of truthful vision, and virtuous action as the product of such vision. This is a picture of the omnipresence of morality and evaluation in human life (p. 39). Such a depiction ought to resonate quite deeply with Christians, something not lost on Murdoch when she writes a few pages earlier: "There are innumerable points at which we have to detach ourselves, to change our orientation, to redirect our desire and refresh and purify our energy, to keep on looking in the right direction: to attend upon the grace that comes through faith " (p. 25). But Murdoch's "grace" and her "truth-seeking as virtue," among other themes, involve something quite different from what Christians... (shrink)
