The classical theory of preference among monetary bets represents people as expected utility maximizers with concave utility functions. Critics of this account often rely on assumptions about preferences over wide ranges of total wealth. We derive a prediction of the theory that bears on bets at any fixed level of wealth, and test the prediction behaviorally. Our results are discrepant with the classical account. Competing theories are also examined in light of our data.

Esta es la versión escrita de una entrevista realizada a Eugenio Bulygin, profesor emérito de Filosofía del Derecho (UBA), con respecto a quien toda presentación podría resultar o bien imcompleta o bien superflua. -/- Nuestra intención al realizar esta entrevista fue indagar acerca de las respuestas que dieron a esos interrogantes las personas que, en ese momento, ocuparon posiciones de toma de decisión en la Facultad de Derecho de la UBA. La elección del entrevistado, Eugenio Bulygin, no podría haber sido (...) mejor. No solo por su lucidez y por haber ocupado un puesto de suma importancia en la transición democrática, el de Decano Normalizador, sino porque, además, ha estado siempre, antes y después de la transición, estrechamente vinculado a la Facultad, de modo que provee un testimonio invaluable de sus transformaciones a lo largo de la segunda mitad del S. XX. (shrink)

Little research has explored the perceptions of military medical providers in the deployed environment and how their perceptions may change over time across an extended military conflict. To our knowledge, no studies have examined military medical providers’ opinions on readiness for their roles in the post-9/11 contingency operations. What has been published indicates that, during the height of Operation Iraqi Freedom, military medical providers often deployed with little notice and minimal formal training. The present report examines data obtained from multiple (...) cohorts of military medical providers (N = 321) deployed to Iraq between 2005 and 2009. Despite varying degrees of support from the U.S. public, our findings indicate that U.S. Air Force military medical providers’ support for the people of Iraq, their belief in the mission, and their ability to influence change did not vary with time.

Despite the lack of invariance problem (the many‐to‐many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side‐stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real‐world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to (...) provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two‐layer network that borrows one element from ASR, long short‐term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human‐like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. (shrink)

In ‘(Really) Defending Exclusionary Reasons’, Monti seeks to defend Raz’ notion of exclusionary reasons from the attack made by Daniel Whiting. Monti agrees with Whiting that exclusionary reasons cannot motivate and so suggests that they operate by guiding rather than motivating. However, Monti’s account of guiding omits the key feature that they can guide even when one’s action is the opposite to what the exclusionary reason seems to recommend. An amended account of what it is to be (...) guided by exclusionary reasons is needed to give the Razian account the explanatory power it is due. (shrink)

Decision making theory in general, and mental models in particular, associate judgment and choice. Decision choice follows probability estimates and errors in choice derive mainly from errors in judgment. In the studies reported here we use the Monty Hall dilemma to illustrate that judgment and choice do not always go together, and that such a dissociation can lead to better decision-making. Specifically, we demonstrate that in certain decision problems, exceeding working memory limitations can actually improve decision choice. We show across (...) four experiments that increasing the number of choice alternatives forces people to collapse choices together, resulting in better decision-making. While choice performance improves, probability judgments do not change, thus demonstrating an important dissociation between choice and probability judgments. We propose the Collapsing Choice Theory (CCT) which explains how working memory capacity, probability estimation, choice alternatives, judgment, and regret all interact and effect decision quality.

Some recent cognitive-scientific research suggests that a considerable amount of intelligent action is generated not by the systematic activity of internal representations, but by complex interactions involving neural, bodily, and environmental factors. Following an analysis of this threat to representational explanation, we pursue an analogy between the role of genes in the production of biological form and the role of neural states in the production of behaviour, in order to develop a notion of genic representation. In both cases an appeal (...) to normal ecological context is used to balance multi-factoral, interactive causal determination against the intuition that certain aspects of the causal nexus play a special role in promoting adaptive success. Certain worries abut this vision help us to get a better grip on the concept of genic representation itself. We end with a puzzle concerning the relation between cognition and representation.

Spike Lee’s film 25 th Hour begins with an act of violence that it does not show: instead, the viewer hears the sounds of a dog being beaten. The dog’s menacing growl is then transformed into the growling image of Montgomery ‘Monty’ Brogan’s car speeding through New York. Monty spots the dog, and stops. It is only then that the viewer witnesses the results of the film’s ‘foundational’ act of violence: the bloody body of a dog beaten to pulp. When (...) Monty approaches the dog, it turns out the animal ‘still has some bite left in him’. Perhaps because the dog is a fighter, Monty decides to save him. Although the dog resists, he ultimately manages to get the dog in the trunk of his car. But Monty does not emerge from the rescue operation unscathed: blood is trickling from a cut in his neck. This scene can be read as a pre-figuration of a stomach-turning scene towards the end of the film, in which Monty’s friend Francis ‘Frank’ Slaughtery will beat up Monty’s face beyond recognition so that Monty will not be raped on his first night in jail. Monty’s face recalls the dog at the beginning of the film. It is through the bloody mess of their bodies that Monty and the dog begin to communicate, to enter into communion. This essay explores how this communion, this communication between Monty and the dog, comes about. I am interested, specifically, in what the significance of such an exploration might be for contemporary conceptions of community. The essay initially approaches this topic against the background of Emmanuel Levinas’ work on ethics, in which the notion of the face has played a crucial role. But its aim is really to situate the film, through the references to the work of Francis Bacon that it includes, in a more contemporary, post-Levinasian debate on an ethics of defacement. I am particularly interested in exploring the significance of such an ethics in the post-September 11 era, which is explicitly evoked at the beginning of Lee’s film. My argument is that Monty and the dog begin to communicate, to enter into a communion, and thus to form a community, through a process of defacement that simultaneously strips them from their ways of life and propels them into a shared ethical and political becoming.

After presenting a variety of arguments in support of the idea that ordinary names are indexical, I respond to John Perry's recent arguments against the indexicality of names. I conclude by indicating some connections between the theory of names defended here and Wittgenstein's observations on naming, and suggest that the latter may have been misconstrued in the literature.

Recent solutions to the curve-fitting problem, described in Forster and Sober ([1995]), trade off the simplicity and fit of hypotheses by defining simplicity as the paucity of adjustable parameters. Scott De Vito ([1997]) charges that these solutions are 'conventional' because he thinks that the number of adjustable parameters may change when the hypotheses are described differently. This he believes is exactly what is illustrated in Goodman's new riddle of induction, otherwise known as the grue problem. However, the 'number of adjustable (...) parameters' is actually a loose way of referring to a quantity that is not language dependent. The quantity arises out of Akaike's theorem in a way that ensures its language invariance. (shrink)

Recent advances in wireless technologies have led to the development of intelligent, in-vehicle safety applications designed to share information about the actions of nearby vehicles, potential road hazards, and ultimately predict dangerous scenarios or imminent collisions. These vehicle safety communication (VSC) technologies rely on the creation of autonomous, self-organizing, wireless communication networks connecting vehicles with roadside infrastructure and with each other. As the technical standards and communication protocols for VSC technologies are still being developed, certain ethical implications of these new (...) information technologies emerge: Coupled with the predicted safety benefits of VSC applications is a potential rise in the ability to surveil a driver engaging in her everyday activities on the public roads. This paper will explore how the introduction of VSC technologies might disrupt the “contextual integrity” of personal information flows in the context of highway travel and threaten one’s “privacy in public.” Since VSC technologies and their related protocols and standards are still in the developmental stage, the paper will conclude by revealing how close attention to the ethical implications of the remaining design decisions can inform and guide designers of VSC technologies to create innovate safety applications that increase public safety, but without compromising the value of one’s privacy in public.

In this paper we will show that Hempel's covering law model can't deal very well with explanations that are based on incomplete knowledge. In particular the symmetry thesis, which is an important aspect of the covering law model, turns out to be problematic for these explanations. We will discuss an example of an electric circuit, which clearly indicates that the symmetry of explanation and prediction does not always hold. It will be argued that an alternative logic for causal explanation is (...) needed. And we will investigate to what extent non-monotonic epistemic logic can provide such an alternative logical framework. Finally we will show that our non-monotonic logical analysis of explanation is not only suitable for simple cases such as the electric circuit, but that it also sheds new light on more controversial causal explanations such as Milton Friedman's explanation of the business cycle.

From high school cafeterias to the floor of Congress, insult is a truly universal and ubiquitous cultural practice with a long and earthy history. And yet, this most human of human behaviors has rarely been the subject of organized and comprehensive attention—until _Toward a Rhetoric of Insult_. Viewed through the lens of the study of rhetoric, insult, Thomas M. Conley argues, is revealed as at once antisocial and crucial for human relations, both divisive and unifying. Explaining how this works and (...) what exactly makes up a rhetoric of insult prompts Conley to range across the vast and splendidly colorful history of offense. Taking in Monty Python, Shakespeare, Eminem, Cicero, Henry Ford, and the Latin poet Martial, Conley breaks down various types of insults, examines the importance of audience, and explores the benign side of abuse. In doing so, Conley initiates readers into the world of insult appreciation, enabling us to regard insults not solely as means of expressing enmity or disdain, but as fascinating aspects of human interaction.

Studies of callosal sexual differentiation have concentrated on global measures of callosal size, using the rat as a model for studies of potential hormonal mechanisms. It is time to shift the study of callosal sexual differentiation to a more cellular level. Finally, there are potential problems with using the female rat as the primary model for understanding hormonal mechanisms during postnatal life.

The framework of Findlay & Walker's target article provides a first attempt to model the saccadic system at all levels. Their scheme is based on two main principles. These are “parallel processing of saccade timing and metrics” and “competitive inhibition through winner-take-all strategies.” In our opinion, however, both concepts are in their strictest sense at odds with the current knowledge of the saccadic system, and need to be refined to make the scheme more relevant.

There is a rather striking video currently used in police training. A firearms officer is caught on video shooting an armed suspect. The officer then gives his account of what happened, and there is no suggestion that he is tying to fabricate evidence. He says that he shot the suspect once; his partner says that he fired two shots. On the video we see four shots being deliberately fired. Memory, it seems, is an unreliable witness in situations of stress.

The aim of this paper is to take the first steps toward providing a refurbished consent theory of political authority, one that rests in part on a reconception of the relationship between the surrender of judgment and the authoritativeness of political institutions. On the standard view, whatever grounds political authority implies that one ought to surrender one's judgment to that of one's political institutions. On the refurbished view, it is the surrender of one's judgment ndash which can plausibly be considered (...) a form of consent ndash that makes political institutions practically authoritative.

This interview with M. Beatrice Fazi explores in detail her work on computation. Focusing in particular upon her recent publications, it covers the themes of contingency and indeterminacy. The questions explore Fazi’s perspectives on computational aesthetics, abstraction and experience. Through an interrogation of the conceptual insights that Fazi’s recent work offers, the interview outlines an agenda for future work in the philosophy of computation and sets forward a series of conceptual policies for seeing the digital, software and data in a (...) fresh light.

The Greeks and Romans have been charged with destroying the ecosystems within which they lived. In this book, however, M. D. Usher argues rather that we can find in their lives and thought the origin of modern ideas about systems and sustainability, important topics for humans today and in the future. With chapters running the gamut of Greek and Roman experience – from the Presocratics and Plato to Roman agronomy and the Benedictine Rule – Plato's Pigs brings together unlikely bedfellows, (...) both ancient and modern, to reveal surprising connections. Lively prose and liberal use of anecdotal detail, including an afterword about the author's own experiments with sustainable living on his sheep farm in Vermont, add a strong authorial voice. In short, this is a unique, first-of-its-kind book that is sure to be of interest to anyone working in Classics, environmental studies, philosophy, ecology, or the history of ideas. (shrink)

Jacob (history, New School for Social Research) proposes that the science of the 17th and 18th centuries was eventually accepted because it was made compatible with larger political and economic interests. A celebration of the recently concluded 33 volume edition of the Collected works of John Stuart Mill, produced over a period of nearly 30 years, the last 20 under the guiding genius (and hand) of general editor Robson. Following a tributary history of the project itself, essays cover Mill's career (...) as a thinker and as a bureaucrat and public servant, exploring the effects of the various milieu--domestic, political, administrative, religious, and cultural--in which he moved.
