In the care of patients with disorders of consciousness (DOC), some ethical difficulties stem from the challenges of accurate diagnosis and the uncertainty of prognosis. Current neuroimaging research on these disorders could eventually improve the accuracy of diagnoses and prognoses and therefore change the context of end-of-life decision making. However, the perspective of healthcare professionals on these disorders remains poorly understood and may constitute an obstacle to the integration of research. We conducted a qualitative study involving healthcare professionals from an (...) acute care university medical center. A short questionnaire captured demographic data as well as the experience of participants with DOC patients. A semi-structured interview was used to explore attitudes toward ethical issues identified in a previous literature review. Qualitative content analysis of interviews was conducted with the NVivo software. Accurate diagnosis among DOC is often regarded as a challenge, but this was generally not the case for our participants because most reported high confidence in DOC diagnoses. However, participants reported struggling with prognosis, especially because of its essential role for end-of-life decision making and communication with families. Variability of opinion between healthcare professionals was reported and identified by some as a minor issue while others stressed how families struggle with different medical opinions. End-of-life decision making encompassed a large proportion of ethical challenges in these patients, and the removal of artificial nutrition and hydration created significant discomfort in a minority of participants. The concept of futility was subject to wide-ranging understandings with both favorable and unfavorable opinions. Our data suggest that to ensure the incorporation of new evidence-based advances, attention should be directed to the real-world practices and challenges of accurate diagnosis and prognosis. Given pervasive challenges in end-of-life care, we recommend improved training of healthcare professionals in the care of patients with DOC, particularly in end-of life care, understanding the context of decision making, and determining how to optimally integrate new neuroscience research on the care of patients with DOC.

We study the relationship between Maxwell and Dirac equations for a class of solutions of Maxwell equations that can represent purely electromagnetic particles.

We present the opinion of some authors who believe there is no force between a stationary charge and a stationary resistive wire carrying a constant current. We show that this force is different from zero and present its main components: the force due to the charges induced in the wire by the test charge and a force proportional to the current in the resistive wire. We also discuss briefly a component of the force proportional to the square of the current (...) which should exist according to some models and another component due to the acceleration of the conduction electrons in a curved wire carrying a dc current (centripetal acceleration). Finally, we analyze experiments showing the existence of the electric field proportional to the current in resistive wires. (shrink)

Building on theoretical and empirical insights and applying the thriving theory as the conceptual framework, the authors developed two new teacher-specific scales, namely the Teacher Stress Scale and the Teacher Thriving Scale. The goal of this investigation was to evaluate the psychometric properties of these two scales. Data were collected through an online questionnaire administered to a national sample of 122 participating early childhood teachers teaching in preschool through third grade in 26 states of the United States during the 2020–2021 (...) school year amidst COVID-19. This study revealed some important psychometric results. First, with respect to their internal structures, both the TSS and the TTS appeared to be best represented as bifactorial and trifactorial, respectively. Specifically, the TSS comprised two constructs: Inadequate School-based Support, and Teaching-related Demands; and the TTS encompassed three constructs: Adaptability and Flexibility, Personal Strengths and Professional Growth, and Positive Mindset. Second, the negative correlation between the TSS and the TTS provided discriminant evidence for each other’s construct validity, while the positive correlations between the TTS and six conceptually cognate constructs demonstrated convergent evidence for construct validity for the TTS. Third, both the overall TSS and the overall TTS as well as their subscales exhibited good internal consistency reliability. Fourth, both the overall TSS and the overall TTS also demonstrated test–retest reliability. (shrink)

Peace is a hallmark of human societies. However, certain ant species engage in long-term intergroup resource sharing, which is remarkably similar to peace among human groups. We discuss how individual and group payoff distributions are affected by kinship, dispersal, and age structure; the challenges of diagnosing peace; and the benefits of comparing convergent complex behaviours in disparate taxa.

Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5-6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor (...) evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.

Ce travail s’insère dans un projet intitulé « Le discours aux frontières du social », qui vise à analyser, dans des films documentaires, l’entrecroisement des différents matériaux en jeu dans ces productions. Pour comprendre comment se formule la critique sociale, j’ai choisi d’analyser deux documentaires ayant pour thème des conflits sociaux : Tereza (« Thérèse », qui met en scène la vie des détenus dans une prison de Campinas) et Boca de Lixo (« Décharge publique », qui présente la vie (...) de personnes qui habitent et travaillent dans les dépôts d’ordures).

This piece replies to a recently published article in the European Journal for Philosophy of Religion by J. L. Schellenberg and Paul Draper. They contend that the field of African philosophy of religion needs renewal, and they make several recommendations on how to achieve this. I agree with their recommendations, but I argue they have omitted a crucial problem and solution to renew the field; namely, a fundamental problem of the field is that it systemically excludes non-Western philosophies and scholars (...) and, therefore, the field needs to be decolonised.

Proof-theoretic semantics provides meanings to the connectives of intuitionistic logic without the need for a semantics in the standard sense of an attribution of semantic values to formulas. Meanings are given by the inference rules that, in this case, do not express preservation of truth but rather preservation of availability of a constructive proof. Elsewhere we presented two paraconsistent systems of natural deduction: the Basic Logic of Evidence and the Logic of Evidence and Truth. The rules of BLE have been (...) conceived to preserve a notion weaker than truth, namely, evidence, understood as reasons for believing in or accepting a given proposition. \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$LET_{J}$$\end{document}, on the other hand, is a logic of formal inconsistency and undeterminedness that extends \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$BLE$$\end{document} by adding resources to recover classical logic for formulas taken as true, or false.

This paper reviews the central points and presents some recent developments of the epistemic approach to paraconsistency in terms of the preservation of evidence. Two formal systems are surveyed, the basic logic of evidence (BLE) and the logic of evidence and truth (LET J ), designed to deal, respectively, with evidence and with evidence and truth. While BLE is equivalent to Nelson’s logic N4, it has been conceived for a different purpose. Adequate valuation semantics that provide decidability are given for (...) both BLE and LET J . The meanings of the connectives of BLE and LET J , from the point of view of preservation of evidence, is explained with the aid of an inferential semantics. A formalization of the notion of evidence for BLE as proposed by M. Fitting is also reviewed here. As a novel result, the paper shows that LET J is semantically characterized through the so-called Fidel structures. Some opportunities for further research are also discussed. (shrink)

In this article I examine the metaphysical foundations of Guido de Ruggiero’s liberalism and ask what these can tell us about his changing view of Giovanni Gentile's actualism, which was such an influence on de Ruggiero before the First World War. I argue that de Ruggiero’s ‘actualism’ was never the same as Gentile’s, but was drawn from the same intellectual sources; that the actualist conception of free and self-conscious agency runs through both versions of the doctrine, though interpreted in different (...) ways; and finally that the contrasts between de Ruggiero’s and Gentile’s political allegiances result from something other than their differing interpretations of actualism, which serves, in the end, not so much as a theory as a set of basic principles, images and ideals that each philosopher tried to modify and match to the political circumstances in which he found himself.

J.L. Chretien is a French public intellectual, philosopher and poet, widely published and revered in his home country and in academic circles worldwide. This translation makes his work available to an English-language audience for the first time and a crucial contribution to our understanding of the phenomenology of religious experience.

With contributions by leading scholars in the field, this book is the first collection in the English language devoted to Baumgarten’s aesthetics.

I argue physicalism should be characterized as the thesis that all behavior is law-governed. This characterization captures crucial desiderata for a formulation of physicalism, including its broad import and worldview defining features. It also has more local virtues, such as avoiding Hempel’s dilemma. A particularly important implication, I argue, is that this thesis makes the question of the mind’s physicality turn on what the mind can do- rather than what experience is like.

Information we use to structure our lives is increasingly stored digitally, rather than in biomemory. (Just think: if your online calendar went down, would you know where you are supposed be and at what time next week?) Likewise, with breakthroughs such as those from Google DeepMind and OpenAI, discoveries at the frontiers of knowledge are increasingly due to machine learning (often, applied to massive datasets, extracted from a fast-growing datasphere) rather than to brainbound cognition. It’s hard to deny that knowledge (...) retention and production is becoming increasingly – in various ways – digitised. -/- Digital Knowledge: A Philosophical Investigation is the first book to squarely and rigorously investigate digital knowledge: what it is, how to make sense of it in connection with received theories of knowledge, and where it is going. Key questions J Adam Carter examines along the way are the following: -/- How is mere digital information converted into reliable digital knowledge? To what extent can digital knowledge be vindicated against sceptical challenges, and in what ways might digital knowledge stand distinctively subject to defeat? What is the epistemically optimal way for us to decide which tasks to outsource entirely to intelligent machines, and to what extent is further outsourcing appropriate (or not) to verify the results of that same outsourced cognition? Are there any ways in which the expansion of the datasphere threatens to make knowledge more, rather than easy, to come by? If so, are there any promising ways to safeguard, epistemically, against such threats? Using fascinating examples throughout, such as the recent chess match between Stockfish and Google’s AlphaZero, smartphones and personalisation, Digital Knowledge: A Philosophical Investigation is an ideal for researchers investigating this fascinating area of research at the intersection of traditional mainstream epistemology, the philosophy of cognitive science, the philosophy of technology, and computer science.

In a recent and provocative paper, Matthew Fisher, Mariel Goddu and Frank Keil (2015) have argued, on the basis of experimental evidence, that ‘searching the internet leads people to conflate information that can be found online with knowledge “in the head”’ (2015, 675), specifically, by inclining us to conflate mere access to information for personal knowledge (2015, 674). This chapter has three central aims. First, we briefly detail Fisher et al.’s results and show how, on the basis of recent work (...) in virtue epistemology (e.g., Tiberius and Walker 1998; Roberts and Wood 2007; Tanesini 2016), their interpretation of the data supports the thesis that searching the internet is conducive to the vice of intellectual arrogance. Second, we argue that this arrogance interpretation of the data rests on an implicit commitment to cognitive internalism. Thirdly, we show how the data can be given a very different explanation in light of the hypothesis of extended cognition (e.g., Clark and Chalmers 1998; Clark 2008) – one which challenges the extent to which Fisher et al. are entitled to insist that subjects are actually conflating access to knowledge for personal knowledge in the first place. We conclude by suggesting how, against the background of extended cognition rather than cognitive internalism, we have some reason to think that searching the internet might actually foster (in certain circumstances) virtuous intellectual humility.

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.

Task unrelated thought (TUT) refers to thought directed away from the current situation, for example a daydream. Three experiments were conducted on healthy participants, with two broad aims. First, to contrast distributed and encapsulated views of cognition by comparing the encoding of categorical and random lists of words (Experiments One and Two). Second, to examine the consequences of experiencing TUT during study on the subsequent retrieval of information (Experiments One, Two, and Three). Experiments One and Two demonstrated lower levels of (...) TUT and higher levels of word-fragment completion whilst encoding categorical relative to random stimuli, supporting the role of a distributed resource in the maintenance of TUT. In addition the results of all three experiments suggested that experiencing TUT during study had a measurable effect on subsequent retrieval. TUT was associated with increased frequency of false alarms at retrieval (Experiment One). In the subsequent experiments TUT was associated with no advantage to retrieval based on recollection, by manipulating instructions at encoding (Experiment Two), and/or at retrieval (Experiment Three). The implications of the results of all three experiments are discussed in terms of recent accounts of memory retrieval and conscious awareness. (shrink)
