We suggest that the sensorimotor “theory” of vision is really an unstructured collection of separate ideas, and that much of the evidence cited in its favor at best supports only a subset of these ideas. As an example, we note that work on change blindness does not “vindicate” (or even speak to) much of the sensorimotor framework. Moreover, the ideas themselves are not always internally consistent. Finally, the proposed framework draws on ideas initially espoused by James Gibson, but does little (...) to differentiate itself from those earlier views. For even part of this framework to become testable, it must specify which sources of evidence can support or contradict each of the component hypotheses. (shrink)

As the perfect companion to introduction to ethics courses, Dell'Olio and Simon's reader includes the most influential ethical theories without overwhelming the beginning student. It contains a variety of readings encompassing contemporary and classic philosophers, male and female perspectives of both western and non-western ethical traditions, and readings in both theoretical and applied ethics as well as a section on 'living the good life.' Useful introduction with thought provoking study questions and suggestions for further readings accompany each chapter which (...) make it easier for students to understand and appreciate their reading.

Institutional review boards are almost universally considered to be overworked and understaffed. They also require substantial commitments of time and resources from their members. Although some surveys report average IRB memberships of 15 people or more, federal regulations require only five. We present data on IRB meetings at eight of the top 25 academic medical centers in the United States funded by the National Institutes of Health. These data indicate substantial contributions from primary reviewers and chairs during protocol discussions but (...) little from other members, which implies that it may be possible for smaller IRBs to accomplish the same tasks with no reduction in the quality of review.

Protein–protein interactions are thought to be mediated by domains, which are autonomous folding units of proteins. Recently, a second type of interaction has been suggested, mediated by short segments termed linear motifs, which are related to recognition elements of intrinsically disordered regions. Here, we propose a third kind of protein–protein recognition mechanism, mediated by disordered regions longer than 20–30 residues. Bioinformatics predictions and well‐characterized examples, such as the kinase‐inhibitory domain of Cdk inhibitors and the Wiskott–Aldrich syndrome protein (WASP)‐homology domain 2 (...) of actin‐binding proteins, show that these disordered regions conform to the definition of domains rather than motifs, i.e., they represent functional, evolutionary, and structural units. Their functions are distinct from those of short motifs and ordered domains, and establish a third kind of interaction principle. With these points, we argue that these long disordered regions should be recognized as a distinct class of biologically functional protein domains. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

A distorted representation of one's own body is a diagnostic criterion and core psychopathology of both anorexia nervosa (AN) and bulimia nervosa (BN). Despite recent technical advances in research, it is still unknown whether this body image disturbance is characterized by body dissatisfaction and a low ideal weight and/or includes a distorted perception or processing of body size. In this article, we provide an update and meta-analysis of 42 articles summarizing measures and results for body size estimation (BSE) from 926 (...) individuals with AN, 536 individuals with BN and 1920 controls. We replicate findings that individuals with AN and BN overestimate their body size as compared to controls (ES= 0.63). Our meta-regression shows that metric methods (BSE by direct or indirect spatial measures) yield larger effect sizes than depictive methods (BSE by evaluating distorted pictures), and that effect sizes are larger for patients with BN than for patients with AN. To interpret these results, we suggest a revised theoretical framework for BSE that accounts for differences between depictive and metric BSE methods regarding the underlying body representations (conceptual vs. perceptual, implicit vs. explicit). We also discuss clinical implications and argue for the importance of multimethod approaches to investigate body image disturbance. (shrink)

I explore the interrelations between the ontological and aesthetic issues raised by ready-mades such as Duchamp’s Fountain. I outline a hylomorphic metaphysics which has two central features. First, hylomorphically complex objects have matter to which they are not identical. Secondly, when such objects are artefacts (including artworks), it is essential to them that they are the products of creative work on their matter. Against this background, I suggest that ready-mades are of aesthetic interest because they pose a dilemma. Is there (...) really an object, a sculpture, that is distinct from its matter, a urinal, which object is created merely by the artist’s choice of the urinal? Or are we dealing with a case in which an artist passes off something, a urinal, as if it were a sculpture, even though it is not one? (shrink)

I argue that it is rational for a person to believe the conjunction of her beliefs. This involves responding to the Lottery and Preface Paradoxes. In addition, I suggest that in normal circumstances, what it is to believe a conjunction just is to believe its conjuncts.

Dialog is a joint action at different levels. At the highest level, the goal of interlocutors is to align their mental representations. This emerges from joint activity at lower levels, both concerned with linguistic decisions (e.g., choice of words) and nonlinguistic processes (e.g., alignment of posture or speech rate). Because of the high‐level goal, the interlocutors are particularly concerned with close coupling at these lower levels. As we illustrate with examples, this means that imitation and entrainment are particularly pronounced during (...) interactive communication. We then argue that the mechanisms underlying such processes involve covert imitation of interlocutors’ communicative behavior, leading to emulation of their expected behavior. In other words, communication provides a very good example of predictive emulation, in a way that leads to successful joint activity. (shrink)

Loss aversion can occur in riskless and risky choices. We present novel evidence on both in a non-student sample (660 randomly selected customers of a car manufacturer). We measure loss aversion in riskless choice in endowment effect experiments within and between subjects and find similar levels of average loss aversion in both. The subjects of the within study also participate in a simple lottery choice task which arguably measures loss aversion in risky choices. We find substantial heterogeneity in both measures (...) of loss aversion. Loss aversion in riskless choice and loss aversion in risky choice are strongly positively correlated, but on average riskless loss aversion is higher than risky loss aversion. We find that in both choice tasks, loss aversion increases in age, income, and wealth, and decreases in education. Our results provide novel supportive input to the debate about the reality of loss aversion. (shrink)

If science fiction is a genre, then attempts to think about the nature of science fiction will be affected by one’s understanding of what genres are. I shall examine two approaches to genre, one dominant but inadequate, the other better, but only occasionally making itself seen. I shall then discuss several important, interrelated issues, focusing particularly on science fiction : what it is for a work to belong to a genre, the semantics of genre names, the validity of attempts to (...) define genres, and the connections between genre and normativity. One important but neglected clue to the nature of genres lies in the kinds of disagreements they generate over the assignment of works to genres. I conclude by explaining why these disagreements tell us something about the nature of genres, and discussing in some detail two famous cases of disagreement about whether some work or works are science fiction.

This article researches how a corporate code of ethics (CCE) implemented in local government X has influenced the behavior of its employees, middle managers, and managers. Metaphors from the existing and desired CCE elicited by these three groups provided information on how to improve the effectiveness of the CCE. This method proved to be very fruitful. It appeared that continuous systematic attention needed to be paid to the CCE after the CCE had been implemented, particularly by management. Initiatives from management (...) to start discussions about relevant questions of integrity appeared to be also necessary to make the topic a “normal” topic which employees were no longer afraid to discuss. In this way, the possibility could be created to develop collectively a “practical” frame of reference concerning relevant questions of integrity that would help employees to make decisions in difficult situations during their work in the future.

Game theory has a prominent role in evolutionary biology, in particular in the ecological study of various phenomena ranging from conflict behaviour to altruism to signalling and beyond. The two central methodological tools in biological game theory are the concepts of Nash equilibrium and evolutionarily stable strategy. While both were inspired by a dynamic conception of evolution, these concepts are essentially static—they only show that a population is uninvadable, but not that a population is likely to evolve. In this article, (...) we argue that a static methodology can lead to misleading views about dynamic evolutionary processes. We advocate, instead, a more pluralistic methodology, which includes both static and dynamic game theoretic tools. Such an approach provides a more complete picture of the evolution of strategic behaviour. 1 Introduction2 The Equilibrium Methodology3 Common Interest Signalling3.1 Lewis’s signalling game3.2 Static analysis3.3 Dynamic analysis4 The Sir Philip Sidney Game4.1 Static analysis4.2 Other equilibria4.3 Dynamic analysis5 Related Literature6 Static and Dynamic Approaches.

We study the handicap principle in terms of the Sir Philip Sidney game. The handicap principle asserts that cost is required to allow for honest signalling in the face of conflicts of interest. We show that the significance of the handicap principle can be challenged from two new directions. Firstly, both the costly signalling equilibrium and certain states of no communication are stable under the replicator dynamics ; however, the latter states are more likely in cases where honest signalling should (...) apply. Secondly, we prove the existence and stability of polymorphisms where players mix between being honest and being deceptive and where signalling costs can be very low. Neither the polymorphisms nor the states of no communication are evolutionarily stable, but they turn out to be more important for standard evolutionary dynamics than the costly signalling equilibrium.

Certain organoid subtypes are particularly sensitive. We explore whether moral intuitions about the heartbeat warrant unique moral consideration for newly advanced contracting cardiac organoids. Despite the heartbeat’s moral significance in organ procurement and abortion discussions, we argue that this significance should not translate into moral implications for cardiac organoids.

One of the main contributions of Richard Bradley’s book is an elegant extension of Jeffrey’s Logic of Decision that countenances the evaluation of conditional prospects. This extension offers a promising new setting in which to model dynamic choice. In Bradley’s framework, plans can be understood as conditionals of an appropriate sort, while dynamic consistency can be viewed as providing a constraint on the evaluation of conditionals across time. In this paper, we study connections between planning conditionals and dynamic consistency.

Musical Platonists identify musical works with abstract sound structures but this implies that they are not created but only discovered. Jerrold Levinson adapts Platonism to allow for creation by identifying musical works with indicated sound structures. In this paper I explore the similarities between Levinson's view and Kit Fine's theory of qua objects. Fine offers the theory of qua objects as an account of constitution, as it obtains, for example, between a statue and the clay the statue is made out (...) of. I argue that Fine's theory does not adequately characterize the constitution relation and that the problems it faces extend to Levinson's account of musical works as indicated structures. I develop an alternative theory of constitution, based on the notion of being made out of. This approach to constitution enables me to offer an account of musical works as abstract objects that are constituted by sound structures. I argue that my account has several advantages over the Levinson/Fine approach. (shrink)

Memes, of the kind found often on the internet, are an increasingly significant medium of expressive activity. I develop a theory of their ontological nature and, in parallel, an analysis of the concept meme. On my view, memes are abstract artifacts made out of norms for production of instances. The norms say things like ‘use a certain image; add text of a certain kind; the text should be delivered in two chunks, one at the top of the image, one at (...) the bottom, etc.’ Instances of these memes are created when users follow these norms and publish the results. The concept meme is analyzed in terms of the notion of memographic practice, a historically situated form of activity within which memes are created and their instances produced and made public.

We study a low-rationality learning dynamics called probe and adjust. Our emphasis is on its properties in games of information transfer such as the Lewis signaling game or the Bala-Goyal network game. These games fall into the class of weakly better reply games, in which, starting from any action profile, there is a weakly better reply path to a strict Nash equilibrium. We prove that probe and adjust will be close to strict Nash equilibria in this class of games with (...) arbitrarily high probability. In addition, we compare these asymptotic properties to short-run behavior. (shrink)

The handicap principle is one of the most influential ideas in evolutionary biology. It asserts that when there is conflict of interest in a signaling interaction signals must be costly in order to be reliable. While in evolutionary biology it is a common practice to distinguish between indexes and fakable signals, we argue this dichotomy is an artifact of existing popular signaling models. Once this distinction is abandoned, we show one cannot adequately understand signaling behavior by focusing solely on cost. (...) Under our reframing, cost becomes one—and probably not the most important—of a collection of factors preventing deception. (shrink)

Constitution is the relation between something and what it is made of. Composition is the relation between something and its parts. I examine three different approaches to the relation between constitution and composition. One approach, associated with neo-Aristotelians like Mark Johnston and Kathrin Koslicki, identifies constitution with composition. A second, popular with those sympathetic to classical mereology such as Judith Thomson, defines constitution in terms of parthood. A third, advocated strongly by Lynne Baker, takes constitution to be somehow inconsistent with (...) relations of parthood. All of these approaches, I argue, face serious problems. I conclude, tentatively, that constitution and composition have nothing to do with each other. (shrink)

This study analyses the sensitivity of public goods contributions through the lens of psychological motives. We report the results of a public goods experiment in which subjects were induced with the motives of care and anger through autobiographical recall. Subjects’ preferences, beliefs, and perceptions under each motive are compared with those of subjects experiencing a neutral autobiographical recall control condition. We find, but only for those subjects with the highest comprehension of the game, that care elicits significantly higher contributions than (...) anger, with the control treatment in between. This positive influence of the care motive on unconditional giving is accounted for partly by preferences for giving and partly by beliefs concerning greater contributions by others. Anger also affects attention to own and other’s payoffs and perceptions of the game’s incentive structure. (shrink)

In the reported, experiment participants hit a ball to aim at the vertex of a Müller–Lyer configuration. This configuration either remained stable, changed its shaft length or the orientation of the tails during movement execution. A significant illusion bias was observed in all perturbation conditions, but not in the stationary condition. The illusion bias emerged for perturbations shortly after movement onset and for perturbations during execution, the latter of which allowed only a minimum of time for making adjustments . These (...) findings indicate that allocentric information is exploited for online control when people make rapid adjustments in response to a sudden change in the environment and not when people guide their limb movements to interact with a stable environment.

Inspired by Sara Ahmed’s notion of ‘queer use,’ I present and extend a neo-Aristotelian theory of artifacts to capture what I call ‘counter-use.’ The theory of artifacts is based on the idea that what they are, how they come to be, and what their functions are cannot be understood independently from each other. They come to exist when a maker imposes the concept of their substantial kind onto some matter by working on the matter to make an artifact of that (...) kind out of it. The extensions to this core theory that I describe are two. First, I show how using can be a kind of making and how disparate users may form what Benedict Anderson calls an imagined community. Second, I describe what I call an artifact’s historicity and suggest that, like its substantial kind, an artifact’s historicity is essential to it. On this basis, I characterize counter-use as use of an artifact by an imagined community that re-arranges an object’s historicity and hence brings into existence a numerically distinct object. Thus, politically motivated counter-use has genuine ontological implications. (shrink)

In 1956, W.B. Gallie introduced his idea of essentially contested concepts. In my paper, I offer a novel interpretation of his theory and argue that his theory, thus interpreted, is correct. The key to my interpretation lies in a condition Gallie places on essentially contested concepts that other interpreters downplay or dismiss: that the use of an essentially contested concept must be derived “from an original exemplar whose authority is acknowledged by all the contestant users of the concept.” This reveals (...) a similarity between Gallie’s views and the semantic externalist views of Hilary Putnam, and others, about natural kind terms like “water” and “tiger.” I argue that natural kind terms and terms for essentially contested concepts are two species of a single semantic genus. In the case of natural kind terms, a term refers to a natural kind, the exemplars are instances of that kind, and the relation between the exemplars and anything to which the term applies is co-membership of the kind. In the case of terms for essentially contested concepts, a term refers to an historical tradition, the exemplar is a stage or temporal part of that tradition, and the relation between the exemplar and anything to which the term refers is being the heir of. This allows me to understand the contests that alerted Gallie to the phenomenon of essentially contested concepts as contests over the ownership of historical traditions. (shrink)

I argue for the thesis (UL) that there are certain logical abilities that any rational creature must have. Opposition to UL comes from naturalized epistemologists who hold that it is a purely empirical question which logical abilities a rational creature has. I provide arguments that any creatures meeting certain conditions—plausible necessary conditions on rationality—must have certain specific logical concepts and be able to use them in certain specific ways. For example, I argue that any creature able to grasp theories must (...) have a concept of conjunction subject to the usual introduction and elimination rules. I also deal with disjunction, conditionality and negation. Finally, I put UL to work in showing how it could be used to define a notion of logical obviousness that would be well suited to certain contexts—e.g. radical translation and epistemic logic—in which a concept of obviousness is often invoked.
