Using the concept of progress measure, we give a new proof of Rabin's fundamental result that the languages defined by tree automata are closed under complementation. To do this we show that for certain infinite games based on tree automata, an immediate determinacy property holds for the player who is trying to win according to a Rabin acceptance condition. Immediate determinancy is stronger than the forgetful determinacy of Gurevich and Harrington, which depends on more information about the past, but applies (...) to another class of games. Next, we show a graph theoretic duality theorem for winning conditions. Finally, we present an extended version of Safra's determinization construction. Together, these ingredients and the determinacy of Borel games yield a straightforward recipe for complementing tree automata. Our construction is almost optimal, i.e. the state space blow-up is essentially exponential- thus roughly the same as for automata on finite or infinite words. To our knowledge, no prior constructions have been better than double exponential. (shrink)

Priority setting in health care is ubiquitous and health authorities are increasingly recognising the need for priority setting guidelines to ensure efficient, fair, and equitable resource allocation. While cost-effectiveness concerns seem to dominate many policies, the tension between utilitarian and deontological concerns is salient to many, and various severity criteria appear to fill this gap. Severity, then, must be subjected to rigorous ethical and philosophical analysis. Here we first give a brief history of the path to today’s severity criteria in (...) Norway and Sweden. The Scandinavian perspective on severity might be conducive to the international discussion, given its long-standing use as a priority setting criterion, despite having reached rather different conclusions so far. We then argue that severity can be viewed as a multidimensional concept, drawing on accounts of need, urgency, fairness, duty to save lives, and human dignity. Such concerns will often be relative to local mores, and the weighting placed on the various dimensions cannot be expected to be fixed. Thirdly, we present what we think are the most pertinent questions to answer about severity in order to facilitate decision making in the coming years of increased scarcity, and to further the understanding of underlying assumptions and values that go into these decisions. We conclude that severity is poorly understood, and that the topic needs substantial further inquiry; thus we hope this article may set a challenging and important research agenda. (shrink)

This essay reconstructs the place of utopia in realist political theory, by examining the ways in which the literary genre of critical utopias can productively unsettle ongoing discussions about “how to do political theory.” I start by analyzing two prominent accounts of the relationship between realism and utopia: “real utopia” and “dystopic liberalism”. Elaborating on Raymond Geuss’s recent reflections, the essay then claims that an engagement with literature can shift the focus of these accounts. Utopian fiction, I maintain, is useful (...) for comprehending what is and for contemplating what might be. Ursula K. Le Guin’s novel The Dispossessed deploys this double function in an exemplary fashion: through her dynamic and open-ended portrayal of an Anarchist community, Le Guin succeeds in imagining a utopia that negates the status quo, without striving to construct a perfect society. The book’s radical, yet ambiguous, narrative hence reveals a strategy for locating utopia within realist political theory that moves beyond the positions dominating the current debate. Reading The Dispossessed ultimately demonstrates that realism without utopia is status quo–affirming, while utopia without realism is wishful thinking. (shrink)

The associative theory of creativity states that creativity is associated with differences in the structure of semantic memory, whereas the executive theory of creativity emphasises the role of top-down control for creative thought. For a powerful test of these accounts, individual semantic memory structure was modelled with a novel method based on semantic relatedness judgements and different criteria for network filtering were compared. The executive account was supported by a correlation between creative ability and broad retrieval ability. The associative account (...) was independently supported, when network filtering was based on a relatedness threshold, but not when it was based on a fixed edge number or on the analysis of weighted networks. In the former case, creative ability was associated with shorter average path lengths and higher clustering of the network, suggesting that the semantic networks of creative people show higher small-worldness.

This article highlights the continuing relevance of a classic bioethical text, “Bioethics as a Discipline,” published by the Hastings Center’s cofounder Daniel Callahan in 1973. Connecting the text’s programmatic recommendations with later reflections and interventions Callahan wrote about the development of bioethics illuminates how the vision Callahan established and the reality this vision helped create were interrelated—just not in the way Callahan had hoped for. Although this portrait relies on an individual perception of the development of bioethics, it might nevertheless, (...) through its unique linkage of different bioethical temporalities, contribute to a broader reassessment of what bioethics became and why.

After critical appraisal of mathematical and biological characteristics of the model, we discuss how a classical hippocampal neural network expresses functions similar to those of the chaotic model, and then present an alternative stimulus-driven chaotic random recurrent neural network (RRNN) that learns patterns as well as sequences, and controls the navigation of a mobile robot.

Poly(ADP‐ribosyl)ation is a post‐translational modification occurring in the nucleus. The most abundant and best‐characterized enzyme catalyzing this reaction, poly(ADP‐ribose) polymerase 1 (PARP1), participates in fundamental nuclear events. The enzyme functions as molecular “nick sensor”. It binds with high affinity to DNA single‐strand breaks resulting in the initiation of its catalytic activity. Activated PARP1 promotes base excision repair. In addition, PARP1 modifies several transcription factors and thereby precludes their binding to DNA. We propose that a major function of PARP1 includes the (...) silencing of transcription preventing expression of damaged genes. Concomitant stimulation of DNA repair suggests that PARP1 acts as a switch between transcription and DNA repair. Another PARP‐type enzyme, tankyrase, is involved in the regulation of telomere elongation. Tankyrase modifies a telomere‐associated protein and thereby prevents it masking telomeric repeats providing access of telomerase for telomere elongation. Therefore, poly(ADP‐ribosyl)ation reactions may act as molecular switches in DNA metabolism. BioEssays 23:543–548, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Mathias Frisch provides the first sustained philosophical discussion of conceptual problems in classical particle-field theories. Part of the book focuses on the problem of a satisfactory equation of motion for charged particles interacting with electromagnetic fields. As Frisch shows, the standard equation of motion results in a mathematically inconsistent theory, yet there is no fully consistent and conceptually unproblematic alternative theory. Frisch describes in detail how the search for a fundamental equation of motion is partly driven by pragmatic considerations (...) (like simplicity and mathematical tractability) that can override the aim for full consistency. The book also offers a comprehensive review and criticism of both the physical and philosophical literature on the temporal asymmetry exhibited by electromagnetic radiation fields, including Einstein's discussion of the asymmetry and Wheeler and Feynman's influential absorber theory of radiation. Frisch argues that attempts to derive the asymmetry from thermodynamic or cosmological considerations fail and proposes that we should understand the asymmetry as due to a fundamental causal constraint. The book's overarching philosophical thesis is that standard philosophical accounts that strictly identify scientific theories with a mathematical formalism and a mapping function specifying the theory's ontology are inadequate, since they permit neither inconsistent yet genuinely successful theories nor thick causal notions to be part of fundamental physics.

Much has been written on the role of causal notions and causal reasoning in the so-called 'special sciences' and in common sense. But does causal reasoning also play a role in physics? Mathias Frisch argues that, contrary to what influential philosophical arguments purport to show, the answer is yes. Time-asymmetric causal structures are as integral a part of the representational toolkit of physics as a theory's dynamical equations. Frisch develops his argument partly through a critique of anti-causal arguments and (...) partly through a detailed examination of actual examples of causal notions in physics, including causal principles invoked in linear response theory and in representations of radiation phenomena. Offering a new perspective on the nature of scientific theories and causal reasoning, this book will be of interest to professional philosophers, graduate students, and anyone interested in the role of causal thinking in science.

Cet essai à teneur philosophique s'intéresse à la force d'évocation et d'invocation de la musique. à son charme magique dirait Nietzsche. Comment la musique me parle-t-elle '? Que suggère-t-elle? Pourquoi parle-t-elle de moi? Quelle fonction a-t-elle dans l'humanité '? L'argumentation de l'auteur utilise la philosophie et la psychologie musicales afin d'expliquer la scandaleuse disproportion entre la puissance à dire de la musique et l'inévidence foncière de ce qu'elle dit (pour reprendre les mots de Jankelé?itch). disproportion en laquelle réside selon l'auteur (...) tout son mystère, en laquelle réside tout son sens. Ce texte court mais dense s'adresse aux musicologues ainsi qu'à tout lecteur ou musicien éclairé voulant densifier son horizon de compréhension de la musique et de ses effets. Il puise ses exemples dans de nombreux corpus : musiques classique et romantique, avant-gardes, jazz, musiques de film."--Page 4 of cover. (shrink)

von Lothar Brock Wer dieses Buch zur Hand nimmt, sollte sich einen Autor vorstellen, der einer Gruppe hartgesottener Geschäftsleute aus der Wüste von New Mexico morgens um sieben mit charmanter Leichtigkeit und spärlichen, aber Verbindung stiftenden Gesten einen Vortrag über die EU als einer vorgestellten Gemeinschaft hält und dafür überschwenglich gefeiert wird. Oder einen Theoretiker mit verblüffend praktischen Kenntnissen über Höhenmedizin und der unter bestimmten Umständen lebensrettenden Fähigkeit, panischen Berggefährten den Anblick der Tiefe erträglich zu machen. Oder den lead-Sänger einer (...) ziemlich professionellen Musikgruppe, die sich die öffentliche Pflege des Liedgutes der Rolling Stones zur Aufgabe gemacht hat und als Meister der Reproduktion die Bewunderer des Originals in Taumel versetzt - von Stockholm bis OfIenbach. Auf keinen Fall aber sollte man sich einen Autor vorstellen wie man ihn sich vorstellt, wenn man dieses Buch zur Hand nimmt. Oder doch? Doch! Es könnte ja sein, daß jemand dieses Buch nicht nur als lohnende Strapaze erlebt, sondern auch als Vergnügen, wenn er erst einmal über den Untertitel hinweggekommen ist.

We argue that the two temporal cognition systems are conceptually too confined to be helpful in understanding the evolution of temporal cognition. In fact, we doubt there are two systems. In relation to this, we question that the authors did not describe the results of our planning study on ravens correctly, as this is of consequence to their theory.

Der Band setzt sich mit den Bedingungen und Möglichkeiten internationalen oder globalen Regierens in einer sozialen Umwelt (Weltgesellschaft) unter drei Perspektiven auseinander: der Perspektive von Theorien globaler Ordnung, der Perspektive spezifischer Formen globaler Ordnungsbildung und der Perspektive die Normativität globaler Ordnung. Die Beiträge des Bandes besetzen Schnittstellen in einer Reihe von Diskussionen, die in den Internationalen Beziehungen zu Ordnung und Ordnungsbildung in der internationalen Politik, zum Regieren jenseits des Nationalstaates, sowie zur Stellung internationaler Politik in der Weltgesellschaft geführt werden.

Evolutionary or biocultural theorizing about horror films has been slow to gain traction in film studies, but the field has seen two recent book publications, Mastering Fear by Rikke Schubart and Primal Roots of Horror Cinema by Carrol L. Fry. Unfortunately, neither book is poised to make a substantial impact on evolutionary horror film theory. Mastering Fear ultimately undermines its own engagement with evolutionary social science, and Primal Roots of Horror Cinema stops short of contributing substantially to the field beyond (...) its compelling argument for the relevance of evolutionary social science to film studies. Plenty of work remains to be done at the fertile junction between evolutionary psychology and horror film. (shrink)

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate describing lists of objects. The confederate’s utterances (to which participants responded) were pre‐recorded and varied in whether they ended in a verb or an object noun and whether this (...) ending was predictable or not. We found that response planning in overlap with sentence‐final verbs evokes larger task‐evoked pupillary responses, while end predictability had no effect. This finding indicates that planning in overlap leads to higher processing load for next speakers in dialog and that next speakers do not proactively modulate the time course of their response planning based on their predictions of turn endings. The turn‐taking system exerts pressure on the language processing system by pushing speakers to plan in overlap despite the ensuing increase in processing load. (shrink)

Zusammenfassung Die öffentliche Finanzierung von Sportangeboten erfolgt aktuell in Form der einseitigen und pauschalen Subventionierung selbstverwalteter Sportanbieter. Diese ist in verteilungspolitischer Hinsicht wenig zielgenau und fuhrt in allokativer Hinsicht zu einer Verzerrung des wettbewerblichen Marktprozesses. Deshalb wird als alternative Finanzierungsform die Subjektförderung erörtert. Als konkrete Gestaltungsvariante wird das Sportgeld, eine individuell zu beantragende und zweckgebundene Erhöhung des Einkommens für Nachfrager nach sportlicher Betätigung, präferiert. Das Sportgeld ermöglicht die gezielte Förderung sozio-ökonomisch benachteiligter Gesellschaftsmitglieder und ist weitgehend frei von unerwünschten Nebenwirkungen auf (...) den Marktprozess. Es bietet die Voraussetzung zur Internalisierung der positiven externen Effekte im Sportbereich und lässt insgesamt Wirtschaftlichkeitsvorteile erwarten. (shrink)

Over the last 20 years, cosmopolitan theories have been benefiting greatly from the dialogue between defenders and critics of world citizenship. Yet, the decidedly polemic aspect of this debate, while allowing for intellectual progress, is also responsible for overdrawn generalizations. Instead of entering into the debate directly, this article attempts to refute a specific anti-cosmopolitan claim raised by Chantal Mouffe. Her realist objection to cosmopolitanism, derived from the conceptual framework of agonistic pluralism, is mistaken at a crucial point: a firm (...) dichotomy between politics and morality cannot provide an alternative to theories of world citizenship, because Mouffe’s embrace of multipolarity as a principle of global politics must equally appeal to a set of universal norms governing international relations. This article argues that even the realist model of multipolarity needs to conceive of a minimal morality to create the symbolic ground on which various power centres can be held accountable.

We provide a new link between deductive and probabilistic reasoning fallacies. Illusory inferences from disjunction are a broad class of deductive fallacies traditionally explained by recourse to a matching procedure that looks for content overlap between premises. In two behavioral experiments, we show that this phenomenon is instead sensitive to real-world causal dependencies and not to exact content overlap. A group of participants rated the strength of the causal dependence between pairs of sentences. This measure is a near perfect predictor (...) of fallacious reasoning by an independent group of participants in illusory inference tasks with the same materials. In light of these results, we argue that all extant accounts of these deductive fallacies require non-trivial adjustments. Crucially, these novel _indirect_ illusory inferences from disjunction bear a structural similarity to seemingly unrelated _probabilistic reasoning_ problems, in particular the conjunction fallacy from the heuristics and biases literature. This structural connection was entirely obscure in previous work on these deductive problems, due to the theoretical and empirical focus on content overlap. We argue that this structural parallelism provides arguments against the need for rich descriptions and individuating information in the conjunction fallacy, and we outline a unified theory of deductive illusory inferences from disjunction and the conjunction fallacy, in terms of Bayesian confirmation theory.

Phillips argues that blindsight is due to response criterion artefacts under degraded conscious vision. His view provides alternative explanations for some studies, but may not work well when one considers several key findings in conjunction. Empirically, not all criterion effects are decidedly non-perceptual. Awareness is not completely abolished for some stimuli, in some patients. But in other cases, it was clearly impaired relative to the corresponding visual sensitivity. This relative dissociation is what makes blindsight so important and interesting.

In a recent extended essay, philosopher Daniel Hausman goes a long way towards dismissing severity as a morally relevant attribute in the context of priority setting in healthcare. In this response, we argue that although Hausman certainly points to real problems with how severity is often interpreted and operationalised within the priority setting context, the conclusion that severity does not contain plausible ethical content is too hasty. Rather than abandonment, our proposal is to take severity seriously by carefully mapping the (...) possibly multiple underlying accounts to well-established ethical theories, in a way that is both morally defensible and aligned with the term’s colloquial uses.

Christians, and those of the Roman Catholic Church, have made significant adjustments to their participation in Sunday liturgy in the wake of the coronavirus disease 2019 (COVID-19) pandemic. This is especially the case for Catholic Christians at the ‘Our Lady of Loreto’ (OLL) Church in Kempton Park in South Africa. Sunday Church services that used to be compulsory for most Catholic families and community members, are now attended by few and in some cases none from staunch Catholic families and communities. (...) However, this is not a new phenomenon in the Catholic Church. It signals the extent to which the COVID-19 pandemic has altered and continues to affect Christian families and their commitment to the Sunday liturgy. Drawing from qualitative interviews conducted with eight staunch Catholic community leaders of OLL Church in Kempton Park, Johannesburg, this paper explores the motivations for their continuous participation and/or non-participation in the Sunday liturgy in the wake of the pandemic. The findings reveal that certain behavioural patterns or activities associated with the COVID-19 pandemic motivate Catholic Christians and families to continue to participate and/or not participate in the Sunday liturgy. Contribution: The article explored and examined the way in which COVID-19 has affected Catholic Christians’ ability to attend Sunday liturgy. It discovered that while some Christians returned to church after the pandemic, others have continued to worship from home because of the influence of changes adopted during the pandemic. (shrink)

In legal academia it is highly controversial how to ‘be original’ in legal research. This article will try to maintain an attitude of tolerance in not promoting or discrediting one particular methodology. Instead, it will identify four different ways of ‘being original’. Perhaps the most common approach is to deal with ‘micro-legal questions’. Many legal academics also pursue research in ‘macro-legal questions’. Less common but growing is the importance of ‘scientific legal research’ and research in ‘non-legal topics’.

Should we be concerned with, or alarmed or outraged by, the insincerity and hypocrisy of politicians who apologize for historical injustice? This paper argues that the correct reply to this question is: sometimes, but not always. In order to establish what types of insincerity must be avoided, Judith Shklar?s hierarchy of ordinary vices is critically revisited. Against Shklar?s overly benign account of hypocrisy, the paper then tries to demonstrate that only institutional and harmful forms of hypocrisy must be rejected in (...) political apologies for historical injustice. Employing Melissa Nobles? ?membership theory?, this paper defends the claim that the sincerity standard for political apologies is, in stark contrast to apologies between individuals, agent independent. This means that in political apologies, rather than focusing on the remorse and regret of the agent who apologizes, we must primarily examine the apology?s consequences in terms of renegotiating the legal, political and affective dimensions of citizenship. In domestic affairs, the paper shows that apologies can only be considered sincere if they push the polity towards a more inclusive conception of membership in the political community. (shrink)

This paper argues for a theory of memory that I have coined “the theory of causal memory processes”. The central claim of the paper is that it is more empirically sound to construct theories of memory in accordance with the theory of causal processes rather than in accordance with causality as regulation. In order to put this claim forward I will, first, describe what kind of function causality serves in philosophical theories of memory. Secondly, I will show that regularity theories (...) of causation is dominant in the causal theories of memory. Thirdly, I will account for the theory of causal processes. Lastly, I will sketch a definition of the theory of causal memory processes. (shrink)

Richard Matheson seeded several weird fish in the deep and dark waters of the American myth pool, not least as a prominent screenwriter for the legendary 1960s TV series The Twilight Zone. I Am Legend, a post-apocalyptic science fiction/horror novel, published in 1954 and set in 1976, remains one of his best known works.1 It shows up persistently on "Best of Horror" lists and is generally regarded as a milestone in modern Gothic fiction.
