We study the extension of dependence logic \ by a majority quantifier \ over finite structures. We show that the resulting logic is equi-expressive with the extension of second-order logic by second-order majority quantifiers of all arities. Our results imply that, from the point of view of descriptive complexity theory, \\) captures the complexity class counting hierarchy. We also obtain characterizations of the individual levels of the counting hierarchy by fragments of \\).

We investigate the application of Courcelle’s theorem and the logspace version of Elberfeld et al. in the context of non-monotonic reasoning. Here we formalize the implication problem for propositional sets of formulas, the extension existence problem for default logic, the expansion existence problem for autoepistemic logic, the circumscriptive inference problem, as well as the abduction problem in monadic second order logic and thereby obtain fixed-parameter time and space efficient algorithms for these problems. On the other hand, we exhibit, for each (...) of the above problems, families of instances of a very simple structure that, for a wide range of different parameterizations, do not have efficient fixed-parameter algorithms (even in the sense of the large class XPnu, resp., XLnu) under standard complexity assumptions.

Zusammenfassung Insbesondere im Alter prägen Determinanten sozialer Ungleichheit das sportliche Handeln sowie die körperliche Verfassung und somit das korporale Kapital von Individuen. Von wesentlicher Bedeutung sind dabei die vertikalen Determinanten sozialer Ungleichheit wie kulturelles, soziales und ökonomisches Kapital. Ziel der Studie war es, direkte und indirekte Beziehungen zwischen den Kapitalarten und sportlichem Handeln zu untersuchen. Die Zusammenhänge wurden auf Basis einer Befragung von N = 320 Personen mittels eines Mediationsmodells überprüft. Der Zusammenhang zwischen dem kulturellen und dem korporalen Kapital wurde (...) darin vollständig durch das soziale Kapital und die Sportaktivität vermittelt. Implikationen für die Rolle des sozialen Kapitals in der Entstehung von sozialer Ungleichheit werden diskutiert. (shrink)

Proponents of zetetic encroachment claim that certain zetetic or inquiry-related considerations can have a bearing on the epistemic rationality of one’s belief formation. Since facts about the interestingness or importance of a topic can be the right kind of reasons for inquisitive attitudes, such as curiosity, and inquisitive attitudes are ways to suspend judgement, these facts also amount to reasons against believing. This mechanism is said to explain several contentious phenomena in epistemology, such as the occurrence of pragmatic encroachment. In (...) this paper, I provide two lines of reasoning against zetetic encroachment. First, on any contrastivist understanding of epistemic reasons, the case in favour of zetetic encroachment loses all its motivational force. Second, the thesis of zetetic encroachment is incompatible with the most promising way to understand degrees of inquisitive attitudes. (shrink)

One recurrent objection to the idea that the right kind of reasons for or against an attitude are object-given reasons for or against that attitude is that object-given reasons for or against belief and disbelief are incapable of explaining certain features of epistemic normativity. Prohibitive balancing, the behaviour of bare statistical evidence, information about future or easily available evidence, pragmatic and moral encroachment, as well as higher-order defeaters, are all said to be inexplicable in terms of those object-given reasons. In (...) this paper, I provide a rebuttal to all these challenges by drawing attention to the object-given reasons for and against the third doxastic state, namely the suspension of judgement. First, I introduce an original picture of how suspension relates to belief and disbelief – as ways of being decided – which yields a novel weighing model of the corresponding reasons. Second, I demonstrate that this new take on doxastic deliberation can accommodate all five features of epistemic normativity. Finally, I extend the weighing model to cover practical deliberation and the suspension of intentions. The resulting theory provides an explanation of why epistemic and practical normativity differ in certain respects in terms of a significant difference between doxastic and conative suspension.

The book examines the discourse on attention emerging in the European Enlightenment (1650-1780) with a focus on German philosophy and literature. It argues that this discourse influenced the formation of aesthetic philosophy in the eighteenth century. Notable figures discussed include René Descartes, G.W.F. Leibniz, Christian Wolff, and Alexander Baumgarten.

According to insulationism, a common take on epistemic value, being of epistemic value does not entail being of value simpliciter. In this paper, I explore one version of insulationism which has so far received little attention in the literature. On this view, epistemic value does not entail value simpliciter because it is a form of attributive goodness, that is, being good as a member of a particular kind. While having a significant advantage over some other formulations of insulationism, I argue (...) that the attributive goodness view of epistemic value should be rejected. On the one hand, shifting to a discussion of attributive goodness comes with several contentious commitments, as well as implausible upshots for epistemic axiology. On the other hand, I demonstrate that one can strengthen other forms of insulationism in such a way that the supposed advantage of the attributive goodness view diminishes. (shrink)

Studying teaching behavior in controlled conditions is difficult. It seems intuitive that a human learner might have trouble reliably recreating response patterns over and over in interaction. A robot would be the perfect tool to study teaching behavior because its actions can be well controlled and described. However, due to the interactive nature of teaching, developing such a robot is not an easy task. As we will show in this review, respective studies require certain robot appearances and behaviors. These mainly (...) should induce teaching behavior in humans, be interactive, match the study design, and be realizable in terms of effort. We discuss how remote controlling of the robot or simulating robot capabilities is used as an option. With this review, we introduce the field of research on studying human teaching behavior with robots as a tool in the experimental design. We will provide a structured overview of existing work, and identify main challenges of employing robots in such studies. (shrink)

Research of tutoring in parent-infant interaction has shown that tutors – when presenting some action – modify both their verbal and manual performance for the learner (‘motherese’, ‘motionese’). Investigating the sources and effects of the tutors’ action modifications, we suggest an interactional account of ‘motionese’. Using video-data from a semi-experimental study in which parents taught their 8- to 11-month old infants how to nest a set of differently sized cups, we found that the tutors’ action modifications (in particular: high arches) (...) functioned as an orienting device to guide the infant’s visual attention (gaze). Action modification and the recipient’s gaze can be seen to have a reciprocal sequential relationship and to constitute a constant loop of mutual adjustments. Implications are discussed for developmental research and for robotic ‘Social Learning’. We argue that a robot system could use on-line feedback strategies (e.g. gaze) to pro-actively shape a tutor’s action presentation as it emerges. (shrink)

This paper defends three theses on the normativity of the suspension of judgment. First, even if beliefs have to fit the truth and disbelief the false, suspension can still have satisfiable fittingness conditions. Second, combining this view with specific theses on the link between fittingness and normative reasons in favour of attitudes commits one to the existence of reasons to suspend judgement, which are neither reasons to believe nor reasons to disbelieve. These independent reasons, in turn, generate a form of (...) epistemic permissivism. Finally, I argue that there are different routes to derive this commitment to independent reasons for suspending judgement. Not only fittingness-centred approaches to epistemic normativity but also many analyses in terms of reasons are committed to this form of epistemic permissivism. (shrink)

Modal dependence logic was introduced recently by Väänänen. It enhances the basic modal language by an operator = (). For propositional variables p 1, . . . , p n , = (p 1, . . . , p n-1, p n ) intuitively states that the value of p n is determined by those of p 1, . . . , p n-1. Sevenster (J. Logic and Computation, 2009) showed that satisfiability for modal dependence logic is complete for nondeterministic (...) exponential time.In this paper we consider fragments of modal dependence logic obtained by restricting the set of allowed propositional connectives. We show that satisfiability for poor man’s dependence logic, the language consisting of formulas built from literals and dependence atoms using ${\wedge, \square, \lozenge}$ (i. e., disallowing disjunction), remains NEXPTIME-complete. If we only allow monotone formulas (without negation, but with disjunction), the complexity drops to PSPACE-completeness.We also extend Väänänen’s language by allowing classical disjunction besides dependence disjunction and show that the satisfiability problem remains NEXPTIME-complete. If we then disallow both negation and dependence disjunction, satisfiability is complete for the second level of the polynomial hierarchy. Additionally we consider the restriction of modal dependence logic where the length of each single dependence atom is bounded by a number that is fixed for the whole logic. We show that the satisfiability problem for this bounded arity dependence logic is PSPACE-complete and that the complexity drops to the third level of the polynomial hierarchy if we then disallow disjunction.In this way we completely classify the computational complexity of the satisfiability problem for all restrictions of propositional and dependence operators considered by Väänänen and Sevenster.

This book comprises a series of essays exploring the transformative insights of Fichte, Herder, Humboldt and the Romantics into the seminal role of language and imagination in shaping human experience and art, including how language, self-consciousness and understanding arise through speech. Along with topics concerning the literary work of art, the philosophy of history, German humanities, philology, and semiotics, the author also discusses the place of phenomenology and the concept of interpretation in literary theory. In highlighting ideas from A. W. (...) Vico, F. Schlegel, Novalis, Germaine de Staël, and Schleiermacher, the author also elucidates romantic poetics, translation, discourse and cultural transfer themes. Das vorliegende Werk umfasst eine Reihe hermeneutischer Abhandlungen des Autors, in deren Fokus die Deutung der Sprachauffassungen Fichtes, Herders, Humboldts und der Romantiker steht. Der Autor untersucht dabei die Formierung von Erfahrung und Kunst durch Sprache und Einbildungskraft sowie die Entstehung von Sprache, Selbstbewusstsein und Verstehen in der Rede. Desgleichen behandelt er Semiotik, Philologie und Philosophie der Geschichte, sowie die Rolle der Phänomenologie und des Interpretationsbegriffs in der Literaturkritik. Im Besonderen hebt der Autor die Auffassungen von Vico, A.W. und F. Schlegel, Novalis, Germaine de Staël, F. Schleiermacher hervor und beleuchtet Übersetzungs-, Diskurs- und Kulturtransfertheorien sowie die Poetik der Romantiker. (shrink)

Scientific knowledge should not only be true, it should be as objective as possible. It should refer to a reality independent of any subject. What can we use as a criterion of objectivity? Intersubjectivity (i.e., intersubjective understandability and intersubjective testability) is necessary, but not sufficient. Other criteria are: independence of reference system, independence of method, non-conventionality. Is there some common trait? Yes, there is: invariance under some specified transformations. Thus, we say: A proposition is objective only if its truth is (...) invariant against a change in the conditions under which it was formulated. We give illustrations from geometry, perception, neurobiology, relativity theory, and quantum theory. Such an objectivist position has many advantages. (shrink)

This paper examines the evolving pattern of gender diversity of the boards of directors of leading Norwegian and British companies on a longitudinal basis. The period covered by the study covers the run up to proposed affirmative action legislation in Norway and, as such, affords an insight into corporate actions in this emerging institutional context. The findings demonstrate that, while board diversity has grown substantially in both countries in recent years, it has done so considerably more rapidly in Norway than (...) in the United Kingdom. The analysis highlights the sectoral variation between the countries in the pattern and growth of board diversity and suggests that the vast majority of the overall growth in board diversity is the result of changing firm behaviour rather than sectoral shift in the United Kingdom or Norwegian economies. It is also shown that as diversity has increased there has been no fall in how experienced female directors are; neither is there evidence of a rise in the number of boards that female directors sit on. This suggests that the rapid growth in board diversity has been achieved without any fall in the quality of female directors. (shrink)

The paper investigates the effects of a humanoid robot’s online feedback during a tutoring situation in which a human demonstrates how to make a frog jump across a table. Motivated by micro-analytic studies of adult-child-interaction, we investigated whether tutors react to a robot’s gaze strategies while they are presenting an action. And if so, how they would adapt to them. Analysis reveals that tutors adjust typical “motionese” parameters. We argue that a robot – when using adequate online feedback strategies – (...) has at its disposal an important resource with which it could proactively shape the tutor’s presentation and help generate the input from which it would benefit most. These results advance our understanding of robotic “Social Learning” in that they suggest a paradigm shift towards considering human and robot as one interational learning system. Keywords: human-robot-interaction; feedback; adaptation; multimodality; gaze; conversation analysis; social learning; pro-active robot conduct. (shrink)

Responsible data management is a multifaceted topic involving standards within the research community regarding research design and the sharing of data as well as the collection, selection, analysis and interpretation of data. Transparency in the manipulation of images is increasingly important in order to avoid misrepresentation of research findings, and research oversight is also critical in helping to assure the integrity of the research process. Intellectual property issues both unite and divide academe and industry in their approaches to data management. (...) Central to the realization and promulgation of responsible data management is clear and careful communication of standards and expectations within the research community to trainees as well as among colleagues. These topics are examined and explored in depth in a special issue of Science and Engineering Ethics on responsible data management. (shrink)
