© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Hannah Arendt a un problème avec la philosophie. Si elle en joue et provoque, le trait s’avère constant, tout au long de sa vie, publique comme privée. Jamais elle ne cacha son peu d’appétence pour les « diseur[s] professionnel[s] de vérité »1. Elle poussa même le vice jusqu’à déclarer, en réponse à Günther Gauss qui, lors d’une célèbre entrevue datant de 1964 et tel le frais cabri qui, avec candeur et bonheur, se dirige guilleret, primesautier, vers la surprise party que (...) donne le loup en son...

Rémi Tison Dans cet article, je traite de la nature des processus cognitifs sous-tendant nos attributions d’états mentaux aux animaux non humains. Selon la conception traditionnelle, nous n’avons qu’un accès indirect aux états mentaux d’autrui, qui doivent être inférés sur la base du comportement. Cette conception traditionnelle influence autant les débats conceptuels concernant l’esprit des animaux que les recherches empiriques sur la cognition animale. Or de récents travaux sur la cognition sociale humaine avancent plutôt une conception « interactionniste », selon (...) laquelle les états mentaux peuvent parfois être directement perçus dans le comportement. J’applique dans cet article la conception interactionniste à l’attribution d’états mentaux aux animaux. Je conclus que celle-ci rend mieux compte des attitudes du sens commun à l’égard des états mentaux des animaux et est plus féconde pour la recherche empirique sur la cognition animale que la conception traditionnelle.

We argue that thought insertion primarily involves a disruption of the sense of ownership for thoughts and that the lack of a sense of agency is but a consequence of this disruption. We defend the hypothesis that this disruption of the sense of ownership stems from a fail- ure in the online integration of the contextual information related to a thought, in partic- ular contextual information concerning the different causal factors that may be implicated in their production. Loss of unity (...) of consciousness, manifested by incoherent subjective experiences is a general phenomenal characteristic of schizophrenia. This loss of coherence has been hypothesized to reflect a generalized deficit of contextual information integration not conveyed by, but related to, a target event. This deficit is manifested across many cog- nitive domains. We argue that it is also manifested in the process of thinking itself, result- ing in causally decontextualized thoughts that are experienced as inserted thoughts. (shrink)

In this paper, I develop an account of linguistic content based on the active inference framework. While ecological and enactive theorists have rightly rejected the notion of content as a basis for cognitive processes, they must recognize the important role that it plays in the social regulation of linguistic interaction. According to an influential theory in philosophy of language, normative inferentialism, an utterance has the content that it has in virtue of its normative status, that is, in virtue of the (...) set of commitments and entitlements that the speaker undertakes by producing this utterance. This normative status is determined by the normative attitudes shared by members of the utterer’s linguistic community. I propose here an account of such normative attitudes based on the ecological interpretation of the active inference framework. I explain how social normativity can be understood in that framework as the way in which members of a group shape their social niche to make it more predictable. Finally, I apply this account of social normativity to basic communicative practices, thereby explaining how social normative expectations can emerge to regulate these communicative practices, eventually leading to the institution of the sort of normative statuses constitutive of linguistic content.

In this paper, we propose an argumentation formalism that allows for both deductive and abductive argumentation, where ‘deduction’ is used as an umbrella term for both defeasible and strict ‘forward’ inference. Our formalism is based on an extended version of our previously proposed information graph formalism, which provides a precise account of the interplay between deductive and abductive inference and causal and evidential information. In the current version, we consider additional types of information such as abstractions which allow domain experts (...) to be more expressive in stating their knowledge, where we identify and impose constraints on the types of inferences that may be performed with the different types of information. A new notion of attack is defined that captures a crucial aspect of abductive reasoning, namely that of competition between abductively inferred alternative explanations. Our argumentation formalism generates an abstract argumentation framework and thus allows arguments to be formally evaluated. We prove that instantiations of our argumentation formalism satisfy key rationality postulates. (shrink)

Consumer-based datasets are the products of data brokerage firms that agglomerate millions of personal records on the adult US population. This big data commodity is purchased by both companies and individual clients for purposes such as marketing, risk prevention, and identity searches. The sheer magnitude and population coverage of available consumer-based datasets and the opacity of the business practices that create these datasets pose emergent ethical challenges within the computational social sciences that have begun to incorporate consumer-based datasets into empirical (...) research. To directly engage with the core ethical debates around the use of consumer-based datasets within social science research, I first consider two case study applications of consumer-based dataset-based scholarship. I then focus on three primary ethical dilemmas within consumer-based datasets regarding human subject research, participant privacy, and informed consent in conversation with the principles of the seminal Belmont Report.

Considering the urgency of addressing grand challenges that affect human health and achieving the ambitious health targets set by the United Nations’ Sustainable Development Goals, the role of business in improving health has become critical. Yet, our systematic review of the business–health literature reveals that business research focuses primarily on occupational health and safety, health care organizations, and health regulations. To embrace the health externalities generated by business activities, we propose that future research should investigate the conditions under which business (...) articulates and participates in health challenges, engages in multilevel actions toward tackling health challenges, and improves health outcomes and its impact on the health of external stakeholders, including customers and local communities. We also urge business scholars to engage with the public health research community to increase impact. (shrink)

We present and contrast two accounts of cooperative communication, both based on Active Inference, a framework that unifies biological and cognitive processes. The mental alignment account, defended in Vasil et al., takes the function of cooperative communication to be the alignment of the interlocutor's mental states, and cooperative communicative behavior to be driven by an evolutionarily selected adaptive prior belief favoring the selection of action policies that promote such an alignment. We argue that the mental alignment account should be rejected (...) because it neglects the action-oriented nature of cooperative communication, which skews its view of the dynamics of communicative interaction. We introduce our own conception of cooperative communication, inspired by a more radical ecological interpretation of the active inference framework. Cooperative communication, on our ecological conception, serves to guide and constrain the dynamics of the cooperative interaction via the construction and restructuring of shared fields of affordances, in order to reach the local goals of the joint actions in which episodes of cooperative communication are embedded. We argue that our ecological conception provides a better theoretical standpoint to account for the action-oriented nature of cooperative communication in the active inference framework. (shrink)

We show that MRP + MA implies that ITP(λ, ω 2 ) holds for all cardinal λ ≥ ω 2 . This generalizes a result by Weiß who showed that PFA implies that ITP(λ, ω 2 ) holds for all cardinal λ ≥ ω 2 . Consequently any of the known methods to prove MRP + MA consistent relative to some large cardinal hypothesis requires the existence of a strongly compact cardinal. Moreover if one wants to force MRP + MA (...) with a proper forcing, it requires at least a supercompact cardinal. We also study the relationship between MRP and some weak versions of square. We show that MRP implies the failure of □(λ, ω) for all λ ≥ ω 2 and we give a direct proof that MRP + MA implies the failure of □(λ, ω 1 ) for all λ ≥ ω 2. (shrink)

La Metaphysique d'Aristote culmine dans le livre Lambda (XII). Il resume les livres precedents, puis se lance dans une fantastique description de Dieu, Premier moteur immobile de l'univers et Penser se pensant soi-meme.

This paper examines the question of why consumers engage in ethical consumption. The authors draw on self-affirmation theory to propose that the choice of an ethical product serves a self-restorative function. Four experiments provide support for this assertion: a self-threat increases consumers’ choice of an ethical option, even when the alternative choice is objectively superior in quantity (Study 1) and product quality (Study 2). Further, restoring self-esteem through positive feedback eliminates this increase in ethical choice (Studies 2 and 3). As (...) an additional test of the robustness of our results, a final study examined the effect of self-threat on choice in a field setting (Study 4). The findings indicate that ethical purchases are not just altruistic. They hold purposeful individual value and can help in the self-restorative process. Implications for managers making decisions regarding investment in ethical product features are discussed. (shrink)

In this paper, we introduce an ecological account of communication according to which acts of communication are active inferences achieved by affecting the behavior of a target organism via the modification of its field of affordances. Constraining a target organism’s behavior constitutes a mechanism of socially extended active inference, allowing organisms to proactively regulate their inner states through the behavior of other organisms. In this general conception of communication, the type of cooperative communication characteristic of human communicative interaction is a (...) way of constraining interaction dynamics toward the goals of a given joint action by constructing and altering shared fields of affordances. This account embraces a pragmatist view according to which communication is a form of action aiming to influence the behavior of a target, and stands against the traditional transmission view according to which communication fundamentally serves to convey information. Understanding acts of communication as active inference under an ecological interpretation allows us to link communicative and ultimately linguistic behavior to the biological imperative of minimizing free energy and to emphasize the action-oriented nature of communicative interaction.

A new method of observation is currently emerging in psychiatry, based on data collection and behavioral profiling of smartphone users. Numerical phenotyping is a paradigmatic example. This behavioral investigation method uses computerized measurement tools in order to collect characteristics of different psychiatric disorders. First, it is necessary to contextualize the emergence of these new methods and to question their promises and expectations. The international mental health research framework invites us to reflect on methodological issues and to draw conclusions from certain (...) impasses related to the clinical complexity of this field. From this contextualization, the investigation method relating to digital phenotyping can be questioned in order to identify some of its potentials. These new methods are also an opportunity to test psychoanalysis. It is then necessary to identify the elements of fruitful analysis that clinical experience and research in psychoanalysis have been able to deploy regarding the challenges of digital technology. An analysis of this theme's litterature shows that psychoanalysis facilitates a reflection on the psychological effects related to digital methods. It also shows how it can profit from the research potential offered by new technical tools, considering the progress that has been made over the past fifty years. This cross-fertilization of the potential and limitations of digital methods in mental health intervention in the context of theoretical issues at the international level invites us to take a resolutely non-reductionist position. In the field of research, psychoanalysis offers a specific perspective that can well be articulated to an epistemology of networks. Rather than aiming at a numerical phenotyping of patients according to the geneticists' model, the case formulation method appears to be a serious prerequisite to give a limited and specific place to the integration of smartphones in clinical investigation.

Cassirer and Panofsky: A Philosophical Misunderstanding This paper argues that German art historian and iconologist Erwin Panofsky unintentionally misused the concept of "symbolic form" coined by his friend and colleague, philosopher Ernst Cassirer. Although both shared the same neo-Kantian background, I contend that Panofsky clung to Kant’s dualistic theory of knowledge, while Cassirer explicitly adopted a non-dualistic way of thinking largely inspired by Goethean morphology. That is why Panofsky could distinguish between the "natural" space of perception and the cultural space (...) of artistic representation, when Cassirer refused such a possibility. In so doing, Panofsky proved that he totally missed Cassirer’s point: according to the philosopher of symbolic forms, there is no such thing as a "nature," unless this "nature" is grasped as inherently cultural and historical.

To celebrate forty years of publication, we asked people new to bioethics to tell us what should be next on the docket. We received 195 essays. Here are four we especially like. Bioethics has, until now, focused mainly on those who directly influence human health. It worked to establish guidelines for doctors to follow when treating their patients, and it provided a backbone for ethical human research. Bioethics has done a lot of good, but it is time for the field (...) to branch out to things that affect human health in less obvious ways. Of the things that bioethics must turn its focus to, one of the most pressing issues is establishing a duty of care between pharmaceutical companies and the people they .. (shrink)

Unlike majority of classical and contemporary Indian philosophers, Gandhi was a practical philosopher, an experimentalist and a laboratiorian who developed practical instruments and carried out experiments for the existing life problems without bothering to build a consistent structure of philosophy. For this very reason there seems an ambiguity to call Gandhi as a philosopher. However, it seems to me that Gandhi was a practical philosopher who laid a pragmatic approach and method to his new insights for social and political action (...) of national movement and the reconstruction of modern India without disturbing the social equilibrium.Gandhi exercised such tremendous skill in cooperative participation of our national movement and is rudely regarded as the “Father of pridely Nation”. As he is too skillfully organized his ideals in building a nation he rightfully ascertained as philosopher in the light of Homer’s (the Greek poet) definition to a philosopher. The same practical method is extended to the aspect of religion by Gandhi. (shrink)

Over the past twenty years, the concept of intermediality has emerged as a strategic response that has sought to bypass some of the ills that have plagued the university as an institution.1 Indeed, defined as the study of “nodes of relations, of relationship movements slow enough to seem immobile”, intermediality as an approach has helped fight against the hyper-specialization of research in the humanities. By conceiving of relationships as paramount, it has made it possible to view as counterintuitive the fragmented (...) approach to the real and its representations. Thereby, the social and cultural environment has been relocated to the center of analyses.. (shrink)

Unlike the majority of philosophers, Hannah Arendt was not inclined to look down on common sense. She became convinced of common sense’s invaluable significance for our common world, especially when she came to understand that totalitarianism consists of its undermining. No matter how important the role of the concept in her thought, however, its meaning remains ambiguous insofar as it refers to two related, yet different ‘faculties’, common sense as a cognitive faculty on the one hand and common sense as (...) a faculty of judgment on the other. The aim of this two-part paper is to clarify this complicated relation.The first part sketches the development of the concept and demonstrates how the polemic created by Eichmann in Jerusalem sharpened Arendt’s understanding of the difference between truth and opinion, knowing and judging. Subsequently, it focuses on Arendt’s analysis of common sense as a cognitive faculty, i.e. as a ‘sixth sense’ that enables us to grasp the common and worldly context of our experiences and therefore also enables us to tell truth from falsehood. It is not thinking, with its search for meaning, but our common sense that warrants the revelation of truth and with it the possibility of knowledge . Because truth compels the mind and precludes debate, Arendt distinguishes it sharply from opinion, which is never self-evident.Nevertheless, this distinction does not end, as in Plato, in the hierarchical subordination of opinion to truth . At the same time, Arendt was aware of the powerlessness and vulnerability of truth in the public forum, in spite of its compelling character. This paradox calls for a discussion of Arendt’s view on the possibilities and limitations of modern mass-manipulation. (shrink)

Since their emergence in the 1980s, environmental virtue ethics (EVEs) have aimed to provide an alternative to deontological and consequentialist approaches for guiding ecological actions in the context of the global environmental crisis. The deterioration of the ecological situation and the challenges in addressing collective action problems caused by global changes have heightened interest in these ethics. They offer a framework for meaningful individual actions independently of the commitment of other actors. However, by shifting the focus onto individuals, EVEs appear (...) to grapple with the tension between anthropocentrism and respect for nature, as well as between self-flourishing and concern for other living beings. This article argues that this difficulty is rooted in the neglect within EVEs of the communitarian aspect of ancient virtue ethics. Drawing from Baird Callicott’s ecocentric approach and Val Plumwood’s works, this paper explores the possibility of conceiving ecological communities as collective frameworks in which both public and private virtues are defined and practiced.

Un carottage effectué dans le marais de Malia a permis de reconstituer les grandes étapes de l'évolution de l'environnement du site archéologique entre 6500 av. J.-C. et aujourd'hui. L'étude ne prend en compte, pour l'instant, que les données sédimentaires et des datations au carbone 14. Plusieurs séquences ont été identifiées. La première (6400-4700 av. J.-C.) correspond au remplissage de la dépression, la deuxième (4700-1500 av. J.-C.) voit se former et évoluer le marais lui-même, la troisième (non datée) révèle un événement (...) marin bref, la quatrième (190 av. J.-C.-414 ap. J.-C.) traduit la réinstallation brutale du marais, la cinquième (de 414 ap. J.-C. à nos jours) montre que la surface du marais évolue en fonction du tracé plus ou moins interne du cordon littoral. Il se peut que la séquence 3 corresponde au tsunami engendré par l'explosion du volcan de Santorin mais il est également possible qu'il corresponde au tremblement de terre de 365 ap. J.-C. qui a provoqué un mouvement de bascule important de la Crète, le coin Sud-Ouest se soulevant de 8 à 10 m, le secteur Nord-oriental s'enfonçant simultanément. (shrink)

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly (...) correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information-theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments.

Cet article analyse les évolutions des positions de Marx à propos de la colonisation. Il souligne tout d’abord l’invariant de ces réflexions : la dénonciation de la violence coloniale. Au départ, on trouve une interprétation de la colonisation comme processus de modernisation, puis comme dynamique de destruction-régénération, liée à l’« unification du monde ». L’auteur identifie spécialement les inflexions successives de la pensée de Marx – résolument critique –, au sujet des questions coloniale et nationale, du caractère non linéaire de (...) l’histoire, mais aussi de la différenciation des formations sociales.

In the face of challenging circumstances, many teachers turn to spirituality for sustenance and strength. Yet spirituality’s place in education and in educators’ lives has long been a matter of confusion and contention, not least because of the ambiguity of the term in its common usage. What is its relationship to religion? And what defines it? In this article, I submit that the later work of Michel Foucault offers a helpful approach to spirituality that displaces those questions—drawing attention away from (...) beliefs and/or attitudes professed, and towards the process of practical self-transformation that subjects undertake for the sake of a truth that is actualised in the body. To be spiritual in this sense is more a matter of what one does than what one believes or who one is. To offer a sense of why it matters in the lives of educators, I draw on the experiences of a San Diego high school teacher confronting interlocking personal, professional, and political challenges as a detailed example.

The philosophy of emotion has long been divided over the cognitive nature of emotion. In this paper I argue that this debate suffers from deep confusion over the meaning of “cognition” itself. This confusion has in turn obscured critical substantive agreement between the debate’s principal opponents. Capturing this agreement and remedying this confusion requires re-conceptualizing “the cognitive” as it functions in first-order theories of emotion. Correspondingly, a sketch for a new account of cognitivity is offered. However, I also argue that (...) this new account, despite tacit acceptance by all major theories of emotion, in fact rules out some of the most fundamental and controversial claims of one side of the nature-of-emotion debate, emotional cognitivism.

In everything from philosophical ethics to legal argument to public activism, it has become commonplace to appeal to the idea of human dignity. In such contexts, the concept of dignity typically signifies something like the fundamental moral status belonging to all humans. Remarkably, however, it is only in the last century that this meaning of the term has become standardized. Before this, dignity was instead a concept associated with social status. Unfortunately, this transformation remains something of a mystery in existing (...) scholarship. Exactly when and why did "dignity" change its meaning? And before this change, was it truly the case that we lacked a conception of human worth akin to the one that "dignity" now represents? In this volume, leading scholars across a range of disciplines attempt to answer such questions by clarifying the presently murky history of "dignity," from classical Greek thought through the Middle Ages and Enlightenment to the present day.
