PurposeThe COVID-19 pandemic caused a massive healthcare crisis. To investigate what makes healthcare system resilient and physicians better at coping during a crisis situation, our study investigated the role risk exposure, such as working at COVID-19 entry points, sleep, and perceived work safety played in reducing negative psychological functioning at work, as well as their effects on adverse and potentially fatal incidences of compromised safety and medical errors.MethodsOur study included a representative sample of 1,189 physicians, from all 12 Slovenian regions (...) and all medical occupations, as registered by the Medical Chamber of Slovenia. For the purposes of this study, a Questionnaire of Sleep and Psychological Functioning at Work was developed in the form of an online retrospective self-report. Additionally, our study included items assessing physicians perceived work safety and frequency of negative outcomes during the first month of the Covid-19 epidemic.ResultsPhysicians working at COVID-19 entry points were more likely to experience night awakening, slept less than 5 h per night, experience nightmares, and had lower levels of psychological functioning in comparison to other physicians. Both hypothesized models showed adequate fit. A higher score on the sleep scale has been shown to predict lower levels of negative psychological functioning at work and, indirectly, reduced incidences of compromised safety and medical errors. Contrary to our expectations, no significant direct effect of sleep on compromised safety and medical errors was found. When perceived work safety was added into the model, the model showed improved fit, with perceived work safety predicting better sleep, less negative psychological functioning at work, and less compromised safety.ConclusionSleep and safety both play an important role in reducing negative psychological functioning at work and, by doing so, decreasing the negative and potentially fatal incidents during the pandemic, such as compromised safety and medical errors. Further, research is needed to see how medical guidelines can be updated to ensure physicians sleep and that their safety is protected. (shrink)

Crosslinguistically, the same modal words can be used to express a wide range of interpretations. This crosslinguistic trend supports a Kratzerian analysis, where each modal has a core lexical entry and where the difference between an epistemic and a root interpretation is contextually determined. A long-standing problem for such a unified account is the equally robust crosslinguistic correlation between a modal’s interpretation and its syntactic behavior: epistemics scope high (in particular higher than tense and aspect) and roots low, a fact (...) which has led to proposals that hardwire different syntactic positions for epistemics and roots (cf. Cinque’s hierarchy). This paper argues that the range of interpretations a modal receives is even more restricted: a modal must be keyed to certain time-individual pairs, but not others. I show that this can be captured straightforwardly by minimally modifying the Kratzerian account: modals are relative to an event—rather than a world—of evaluation, which readily provides a time (the event’s running time) and (an) individual(s) (the event’s participants). I propose that this event relativity of modals can in turn explain the correlation between type of interpretation and syntactic position, without stipulation of an interpretation-specific height for modals.

In the World Library of Psychologists series, international experts themselves present career-long collections of what they judge to be their finest pieces – extracts from books, key articles, salient research findings, and their major practical theoretical contributions. Elizabeth Valentine has an international reputation as an eminent scholar and pioneer in the field of philosophy and history of psychology. This selection brings together some of her best work over the last thirty years. A specially written introduction gives an overview of her (...) career and contextualises the selection in relation to changes in the field during this time. The first section on 'Philosophy' covers work on different theoretical approaches to psychology, introspection and the study of consciousness, the mind-body problem, and different types of explanation in psychology including reductionism. The second section, 'From Philosophy to History', includes work on the philosophical psychologists G. F. Stout and James Sully, among others. The third section on 'History' covers Valentine's more recent historical work on the development of psychology in London – both institutional and biographical – and includes accounts of both Bedford College and University College, and the role of pioneer women psychologists. The book enables the reader to trace developments in the philosophy and history of psychology over the last thirty years. It will appeal to anyone with interests in these areas as well as being an invaluable resource for graduate and advanced undergraduate courses in conceptual and historical issues. (shrink)

Hybrid deduction–refutation systems are deductive systems intended to derive both valid and non-valid, i.e., semantically refutable, formulae of a given logical system, by employing together separate derivability operators for each of these and combining ‘hybrid derivation rules’ that involve both deduction and refutation. The goal of this paper is to develop a basic theory and ‘meta-proof’ theory of hybrid deduction–refutation systems. I then illustrate the concept on a hybrid derivation system of natural deduction for classical propositional logic, for which I (...) show soundness and completeness for both deductions and refutations.

Wer bin ich, wenn nicht mein Gehirn? Das menschliche Gehirn ist eine besonders eindrucksvolle Blüte am Baum der biologischen Vielfalt. Dieser Stammbaum hat seine Äste in der Welt entwickelt und ist mit seinen Wurzeln tief in der Natur verankert. Wer aber erkennt die Gesetze der Natur und beobachtet die wundersame Entwicklung des Lebendigen, wenn nicht das Gehirn selbst? Bei dieser Spiegelung des Gehirns in der Welt und der Welt im Gehirn schließt sich ein Kreis, in dem Geist und Stoff nicht (...) mehr als unvereinbare Elemente erscheinen. Im Mittelpunkt der philosophisch-naturwissenschaftlichen Gedanken von Valentin Braitenberg steht der Begriff der Information, der in der Form der Lebewesen als ein Wissen über die Welt aufscheint. Ein geistreicher Fundus für alle, die Lust haben, unsere Existenz in dieser Welt zu verstehen, wie Forscher, Mediziner, Philosophen... Die italienische Ausgabe dieses Buches, "L'immagine del mondo nella testa", wurde mit dem renommierten italienischen Medienpreis "Premio Galileo 2000"L'immagine del mondo nella testa", wurde mit dem renommierten italienischen Medienpreis "Premio Galileo 2000" für das Jahr 2009 ausgezeichnet. Prof. Dr. Dr. h.c. Valentin Braitenberg, Hirnforscher, war u.a. Direktor am Max-Planck-Institut für biologische Kybernetik in Tübingen und Honorarprofessor an den Universitäten Tübingen und Freiburg. Braitenberg bringt das Kunststück fertig, kurzweilig viele Fragen auf amüsante und ebenso intelligente Weise anzureißen und damit den Leser selbst zu befähigen, darüber zu meditieren, wie das Bild der Welt in dessen eigenen Kopf kommt. Gerade in einer Zeit, in der Meditation gerne als gedankenloses Singen von Mantras missverstanden wird, gereichen die cartesianischen Meditationen à la Braitenberg jedem denkenden Menschen zu einem ganz privaten Vergnügen der besonderen Art.

The paper reveals some mostly unnoticed and unexpected trends in reception of novel ideas in science. The author formulates certain principles of the reception of these ideas by scientific communities and justifies them by examples from modern mathematics and non-classical logic.

This is a review of the book: Sheehan H. Marxism and the Philosophy of Science. A Critical History. The First Hundred Years. (L.: Verso, 2017. XII. 450 p.). The keynote of the book serves the conviction that Marxism is a sort of “super-theory” that can explain not only any social and political life, but also profound philosophy of science, including natural science. Science is presented in the book as a form of social practice. The main idea of the Marxist philosophy (...) of science is the status of the theory of dialectical materialism. The author shows that Marxist ideas could be considered as the origins of many disciplines: the sociology of science, the history of science, the history of technology; they had a noticeable effect on non-Marxist thought as well. However, Stalinism and Lysenkoism significantly decelerated the development of the Marxist philosophy of science. (shrink)

Hyperboolean algebras are Boolean algebras with operators, constructed as algebras of complexes (or, power structures) of Boolean algebras. They provide an algebraic semantics for a modal logic (called here a {\em hyperboolean modal logic}) with a Kripke semantics accordingly based on frames in which the worlds are elements of Boolean algebras and the relations correspond to the Boolean operations. We introduce the hyperboolean modal logic, give a complete axiomatization of it, and show that it lacks the finite model property. The (...) method of axiomatization hinges upon the fact that a "difference" operator is definable in hyperboolean algebras, and makes use of additional non-Hilbert-style rules. Finally, we discuss a number of open questions and directions for further research. (shrink)

In this article, I critically reassess Iris Marion Young's late works, which centre on the distinction between liability and social connection responsibility. I concur with Young's diagnosis that structural injustices call for a new conception of responsibility, but I reject several core assumptions that underpin her distinction between two models and argue for a different way of conceptualising responsibility to address structural injustices. I show that Young's categorical separation of guilt and responsibility is not supported by the writings of Hannah (...) Arendt, which Young draws on, and that it is also untenable on independent systematic grounds. Furthermore, I argue that several of Young's other criteria fail to clearly demarcate two distinct phenomena. I therefore propose to transcend Young's distinction between two models in favour of a related, but conceptually different distinction between two forms of responsibility: interactional and structural. Embracing this terminology facilitates the conceptualisation of the general features of responsibility that are shared by both forms, including their retrospective and prospective time-direction and their applicability to individual, joint and group agency. The distinction between interactional and structural responsibility also yields a more compelling general account of the role of background structures, and of blame within ascriptions of political responsibility.

ABSTRACT The paper studies propositional logics in a bimodal language, in which the first modality is interpreted as the local truth, and the second as the universal truth. The logic S4UC is introduced, which is finitely axiomatizable, has the f.m.p. and is determined by every connected separable metric space.

A complete axiomatic system CTL$_{rp}$ is introduced for a temporal logic for finitely branching $\omega^+$-trees in a temporal language extended with so called reference pointers. Syntactic and semantic interpretations are constructed for the branching time computation tree logic CTL$^{*}$ into CTL$_{rp}$. In particular, that yields a complete axiomatization for the translations of all valid CTL$^{*}$-formulae. Thus, the temporal logic with reference pointers is brought forward as a simpler (with no path quantifiers), but in a way more expressive medium for reasoning (...) about branching time. (shrink)

This dissertation argues that on the basis of their elaboration of and appeal to the Virtual, Henri Bergson and Gilles Deleuze operate a profound transformation of the Kantian conception of the transcendental. This implies a novel account of experience and its conditions, resulting in what I call Transcendental Experience---whereby the primary condition of experience, that is, time, becomes immanent to what it conditions. Through this revaluation of the transcendental, Bergson and Deleuze are ultimately providing us with an alternative to both (...) Kant's and Phenomenology's theories of subjectivity. Rooted in real experience rather than abstract forms, this approach points to the primacy of the unconscious over consciousness as the ground of subjectivity. With Bergson and Deleuze, then, it is ultimately to the ontological unconscious that we must refer thought and experience, thereby accounting for a radically novel conception of subjectivity, in terms of inhuman and inorganic difference or alteration rather than some postulated transcendental ego. ;Hoping to provide a contribution to the current scholarship concerning Bergson and Deleuze, I examine closely both what they have in common and where they diverge. Accordingly, I dedicate the first part of the dissertation to a comprehensive examination of Bergsonian metaphysics. I conclude that through his observation of the immediate data of consciousness, perception and memory in terms of concrete duration, he is able to offer a new philosophical method based in an original notion of intuition---a method which, I claim, eventually allows him to solve the problem of dualism. The second part of this project then turns to an examination of Deleuze's Transcendental Empiricism which, I argue, is directly inspired from Bergson's method of intuition. There, I focus on Deleuze's differential ontology, which leads me to an exploration of the role he ascribes to the Sensible, and consequently, to the artistic experience, as the primary ground---which, he shows, is also an ungrounding---of consciousness. Finally, I argue that over and above Bergson's ultimate privileging of continuity, Deleuze's prioritization of discontinuity allows him to address the great traditional philosophical problems while opening the future for thought and experience.

This book represents a first attempt, after the anti-communist Revolution of 1989, to investigate with analytical methods the reliability of the "official philosophy"in the ex-communist countries - the diamat. It is not a factual, historical or politological approach, but a conceptual analysis of two main topics: the "materialism" and the "dialectics". It is mainly focused on the Romanian case.

We study the general problem of axiomatizing structures in the framework of modal logic and present a uniform method for complete axiomatization of the modal logics determined by a large family of classes of structures of any signature.

The paper deals with polymodal languages combined with standard semantics defined by means of some conditions on the frames. So, a notion of "polymodal base" arises which provides various enrichments of the classical modal language. One of these enrichments, viz. the base £(R,-R), with modalities over a relation and over its complement, is the paper's main paradigm. The modal definability (in the spirit of van Benthem's correspondence theory) of arbitrary and ~-elementary classes of frames in this base and in some (...) of its extensions, e.g., £(R,-R,R-1 ,_R-1), £(R,-R,=I=) etc., is described, and numerous examples of conditions definable there, as well as undefinable ones, are adduced.

Der Begriff »Klassische Deutsche Philosophie« setzt sich zusehends gegenüber der alten Bestimmung »Deutscher Idealismus« durch. Dies geschieht vollkommen zu Recht, denn letztere führt in die Irre. Tatsächlich verfolgen Fichte, Schelling und Hegel zusammen mit Kant das Anliegen, Idealismus und Realismus als einseitige Positionen zu überwinden. Ausgehend von diesem gemeinsamen Vorhaben entspinnt sich zwischen ihnen eine Kontroverse, die in unterschiedlichen Lösungskonzepten mündet. Die vorliegende Arbeit stellt die unterschiedlichen Ansätze zur Vermittlung von Idealismus und Realismus, die in der Forschung bisher eher vage (...) präsent sind, erstmals systematisch anhand ihrer historischen Entwicklung dar. Ein Anhang zur Analytischen Philosophie belegt die Relevanz der Fragestellung auch für die Philosophie der Gegenwart. (shrink)

This paper discusses the interaction of aspect and modality, and focuses on the puzzling implicative effect that arises when perfective aspect appears on certain modals: perfective somehow seems to force the proposition expressed by the complement of the modal to hold in the actual world, and not merely in some possible world. I show that this puzzling behavior, originally discussed in Bhatt (1999, Covert modality in non-finite contexts) for the ability modal, extends to all modal auxiliaries with a circumstantial modal (...) base (i.e., root modals ), while epistemic interpretations of the same modals are immune to the effect. I propose that implicative readings are contingent on the relative position of the modal w.r.t. aspect: when aspect scopes over the modal (as I argue is the case for root modals), it forces an actual event, thereby yielding an implicative reading. When a modal element scopes over aspect, no actual event is forced. This happens (i) with epistemics, which structurally appear above tense and aspect; (ii) with imperfective on a root modal: imperfective brings in an additional layer of modality, itself responsible for removing the necessity for an actual event. This proposal enables us to solve the puzzle while maintaining a standardized semantics for aspects and modals. (shrink)

Most large companies and many smaller ones have adopted ethics codes, but the evidence is mixed as to whether they have a positive impact on the behavior of employees. We suggest that one way that ethics codes could contribute to ethical behavior is by influencing the perceptions that employees have about the ethical values of organizations. We examine whether a group of sales professionals in organizations with ethics codes perceive that their organizational context is more supportive of ethical behavior than (...) sales professionals in companies without codes. After accounting for the effect of several covariates, our results indicated that sales professionals employed in organizations with codes of ethics perceived their work environments to have more positive ethical values than did other sales professionals.

How do children learn the meanings of propositional attitude verbs? We argue that children use information contained in both syntactic distribution and pragmatic function to zero in on the appropriate meanings. Specifically, we identify a potentially universal link between semantic subclasses of attitude verbs, their syntactic distribution and the kinds of indirect speech acts they can be used to perform. As a result, children can use the syntax as evidence about the meaning, which in turn constrains the kinds of pragmatic (...) enrichments they do and do not make in understanding these verbs in conversation.

Accusations of hypocrisy are a recurring theme in the public debate on climate change, but their significance remains poorly understood. Different motivations are associated with this accusation, which is leveled by proponents and opponents of climate action. In this article, I undertake a systematic assessment of climate hypocrisy, with a focus on lifestyle and political hypocrisy. I contextualize the corresponding accusation, introduce criteria for the conceptual analysis of climate hypocrisy, and develop an evaluative framework that allows us to determine its (...) moral significance. I argue that different instances of climate hypocrisy are problematic to different degrees, depending on how detrimental they are to an agent's attainment of environmental integrity. The resulting framework helps clear the confusion caused by disinformation campaigners, by distinguishing objectionable uses of the climate hypocrisy charge from constructive ones motivated by genuine concern for integrity.

In this conceptual paper, we propose that both skill set development and mindset development would be desirable dimensions of negotiation training. The second dimension has received little attention thus far, but negotiation mindsets, i.e., the psychological orientations by which people approach negotiations, are likely to have a considerable influence on the outcome of negotiations. Referring to empirical and conceptual mindset studies from outside the negotiation field, we argue that developing mindsets can leverage the effectiveness of skills and knowledge, increase learning (...) transfer, and lead to long-term behavioral changes. We introduce an integrative negotiation mindset that comprises three inclinations which complement each other: a collaborative, a curious, and a creative one. We also discuss activities that help people to develop and enhance this mindset both in and out of the classroom. Our general claim is that by moving beyond the activities of conventional negotiation training, which focuses on skills and knowledge, mindset-oriented negotiation training can increase training effectiveness and enable participants to more often reach what we define as sustainable integrative agreements.
