© 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)

Abstract The content of an emotion, unlike the content of a perception, is directly dependent on the motivational set of the subject experiencing the emotion. Given the instability of this motivational set, it might be thought that there is no sense in which emotions can be said to pick up information about the environment in the same way that perception does. Whereas it is admitted that perception tracks for us what is the case in the environment, no such tracking relation, (...) it is argued, holds between one's emotions and what they are about. It is to this worry – that the construal of the emotions as perceptions inevitably raises – that this paper tries to respond. In this paper, I suggest that when it is realized that one dimension of perception itself is directly dependent on the perceiver's perspective on her environment, then emotion, which is also essentially perspectival in this sense, bears the comparison with perception very well. After having clarified the nature and the role that perspective plays in perception, I argue that, in the case of emotions, the same perspectival role can be played by agents’ long-standing evaluative tendencies and character traits. The resulting conception of emotion as perception is then tested against possible objections. (shrink)

Is shame social? Is it superficial? Is it a morally problematic emotion? Researchers in disciplines as different as psychology, philosophy, and anthropology have thought so. But what is the nature of shame and why are claims regarding its social nature and moral standing interesting and important? Do they tell us anything worthwhile about the value of shame and its potential legal and political applications? -/- In this book, Julien Deonna, Raffaele Rodogno, and Fabrice Teroni propose an original philosophical account (...) of shame aimed at answering these questions. The book begins with a detailed examination of the evidence and arguments that are taken to support what they call the two dogmas about shame: its alleged social nature and its morally dubious character. Their analysis is conducted against the backdrop of a novel account of shame and ultimately leads to the rejection of these two dogmas. On this account, shame involves a specific form of negative evaluation that the subject takes towards herself: a verdict of incapacity with regard to values to which she is attached. One central virtue of the account resides in the subtle manner it clarifies the ways in which the subject's identity is at stake in shame, thus shedding light on many aspects of this complex emotion and allowing for a sophisticated understanding of its moral significance. -/- This philosophical account of shame engages with all the current debates on shame as they are conducted within disciplines as varied as ethics, moral, experimental, developmental and evolutionary psychology, anthropology, legal studies, feminist studies, politics and public polic.

One puzzle concerning highly idealized models is whether they explain. Some suggest they provide so-called ‘how-possibly explanations’. However, this raises an important question about the nature of how-possibly explanations, namely what distinguishes them from ‘normal’, or how-actually, explanations? I provide an account of how-possibly explanations that clarifies their nature in the context of solving the puzzle of model-based explanation. I argue that the modal notions of actuality and possibility provide the relevant dividing lines between how-possibly and how-actually explanations. Whereas how-possibly (...) explanations establish claims of possible explanations, how-actually explanations establish claims of actual ones. Models, in turn, simply provide evidence for these claims. (shrink)

Widespread preservation of fossilized biomolecules in many fossil animals has recently been reported in six studies, based on Raman microspectroscopy. Here, we show that the putative Raman signatures of organic compounds in these fossils are actually instrumental artefacts resulting from intense background luminescence. Raman spectroscopy is based on the detection of photons scattered inelastically by matter upon its interaction with a laser beam. For many natural materials, this interaction also generates a luminescence signal that is often orders of magnitude more (...) intense than the light produced by Raman scattering. Such luminescence, coupled with the transmission properties of the spectrometer, induced quasi‐periodic ripples in the measured spectra that have been incorrectly interpreted as Raman signatures of organic molecules. Although several analytical strategies have been developed to overcome this common issue, Raman microspectroscopy as used in the studies questioned here cannot be used to identify fossil biomolecules.

The emotions are at the centre of our lives and, for better or worse, imbue them with much of their significance. The philosophical problems stirred up by the existence of the emotions, over which many great philosophers of the past have laboured, revolve around attempts to understand what this significance amounts to. Are emotions feelings, thoughts, or experiences? If they are experiences, what are they experiences of? Are emotions rational? In what sense do emotions give meaning to what surrounds us? (...) -/- The Emotions: A Philosophical Introduction introduces and explores these questions in a clear and accessible way. The authors discuss the following key topics: -/- the diversity and unity of the emotions the relations between emotion, belief and desire the nature of values the relations between emotions and perceptions emotions viewed as evaluative attitudes the link between emotions and evaluative knowledge the nature of moods, sentiments, and character traits. -/- Including chapter summaries and guides to further reading, The Emotions: A Philosophical Introduction is an ideal starting point for any philosopher or student studying the emotions. It will also be of interest to those in related disciplines such as psychology and the social sciences. (shrink)

Since Saul Kripke’s influential work in the 1970s, the revisionary approach to semantic paradox—the idea that semantic paradoxes must be solved by weakening classical logic—has been increasingly popular. In this paper, we present a new revenge argument to the effect that the main revisionary approaches breed new paradoxes that they are unable to block.

We cast doubts on the suggestion, recently made by Graham Priest, that glut theorists may express disagreement with the assertion of A by denying A. We show that, if denial is to serve as a means to express disagreement, it must be exclusive, in the sense of being correct only if what is denied is false only. Hence, it can’t be expressed in the glut theorist’s language, essentially for the same reasons why Boolean negation can’t be expressed in such a (...) language either. We then turn to an alternative proposal, recently defended by Beall (in Analysis 73(3):438–445, 2013; Rev Symb Log, 2014), for expressing truth and falsity only, and hence disagreement. According to this, the exclusive semantic status of A, that A is either true or false only, can be conveyed by adding to one’s theory a shrieking rule of the form A & ~A |- \bot, where \bot entails triviality. We argue, however, that the proposal doesn’t work either. The upshot is that glut theorists face a dilemma: they can either express denial, or disagreement, but not both. Along the way, we offer a bilateral logic of exclusive denial for glut theorists—an extension of the logic commonly called LP. (shrink)

RNA polymerase II (RNAP II) non‐coding transcription is now known to cover almost the entire eukaryotic genome, a phenomenon referred to as pervasive transcription. As a consequence, regions previously thought to be non‐transcribed are subject to the passage of RNAP II and its associated proteins for histone modification. This is the case for the nucleosome‐depleted regions (NDRs), which provide key sites of entry into the chromatin for proteins required for the initiation of coding gene transcription and DNA replication. In this (...) review, recent data on the effects of pervasive transcription through NDRs are summarized and a model is proposed to explain how RNAP II‐driven transcription is able to modify the nucleosomes flanking the NDRs, leading to nucleosome repositioning and NDR closure. Even though much of the mechanistic detail underlying these events remains to be elucidated, such a model provides a basis to explain how non‐coding transcription through NDRs can regulate the initiation of coding gene expression and DNA replication.

How does shame differ from guilt? Empirical psychology has recently offered distinct and seemingly incompatible answers to this question. This article brings together four prominent answers into a cohesive whole. These are that (a) shame differs from guilt in being a social emotion; (b) shame, in contrast to guilt, affects the whole self; (c) shame is linked with ideals, whereas guilt concerns prohibitions and (d) shame is oriented towards the self, guilt towards others. After presenting the relevant empirical evidence, we (...) defend specific interpretations of each of these answers and argue that they are related to four different dimensions of the emotions. This not only allows us to overcome the conclusion that the above criteria are either unrelated or conflicting with one another, it also allows us to tell apart what is constitutive from what is typical of them. -/- .

It is sometimes held that rules of inference determine the meaning of the logical constants: the meaning of, say, conjunction is fully determined by either its introduction or its elimination rules, or both; similarly for the other connectives. In a recent paper, Panu Raatikainen (2008) argues that this view - call it logical inferentialism - is undermined by some "very little known" considerations by Carnap (1943) to the effect that "in a definite sense, it is not true that the standard (...) rules of inference" themselves suffice to "determine the meanings of [the] logical constants" (p. 2). In a nutshell, Carnap showed that the rules allow for non-normal interpretations of negation and disjunction. Raatikainen concludes that "no ordinary formalization of logic ... is sufficient to `fully formalize' all the essential properties of the logical constants" (ibid.). We suggest that this is a mistake. Pace Raatikainen, intuitionists like Dummett and Prawitz need not worry about Carnap's problem. And although bilateral solutions for classical inferentialists - as proposed by Timothy Smiley and Ian Rumfitt - seem inadequate, it is not excluded that classical inferentialists may be in a position to address the problem too.

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

One can find in the literature two sets of views concerning the relationship between understanding and explanation: that one understands only if 1) one has knowledge of causes and 2) that knowledge is provided by an explanation. Taken together, these tenets characterize what I call the narrow knowledge account of understanding. While the first tenet has recently come under severe attack, the second has been more resistant to change. I argue that we have good reasons to reject it on the (...) basis of theoretical models that provide how-possibly explanations. These models, while they do not explain in the strict sense, afford understanding. In response, I propose an alternative epistemology of understanding, broad KAU, that takes cases of theoretical modelling into account. (shrink)

In this paper, we develop a fresh understanding of the sense in which emotions are evaluations. We argue that we should not follow mainstream accounts in locating the emotion–value connection at the level of content and that we should instead locate it at the level of attitudes or modes. We begin by explaining the contrast between content and attitude, a contrast in the light of which we review the leading contemporary accounts of the emotions. We next offer reasons to think (...) that these accounts face substantial problems since they locate the link emotions bear to values at the level of content. This provides the incentive to pursue an alternative approach according to which emotions qualify as evaluations because they are specific types of attitudes, an approach we substantiate by appealing to felt bodily stances. We conclude by considering two reasons why this approach may be resisted; they respectively pertain to the alleged impossibility of drawing the attitude–content contrast in the case of the emotions and to the suspicion that so doing raises qualia-related worries.

In this article, the authors examine and debate the categories of emotions, moods, temperaments, character traits and sentiments. They define them and offer an account of the relations that exist among the phenomena they cover. They argue that, whereas ascribing character traits and sentiments (dispositions) is to ascribe a specific coherence and stability to the emotions (episodes) the subject is likely to feel, ascribing temperaments (dispositions) is to ascribe a certain stability to the subject's moods (episodes). The rationale for this (...) distinction, the authors claim, lies in the fact that, whereas appeal to character traits or sentiments in explanation is tantamount to making sense of a given behaviour in terms of an individual's specific evaluative perspective - as embodied in this individual's emotional profile - appeal to temperaments makes sense of it independently of any such evaluative perspective.

Argumentation has been an important topic in knowledge representation, reasoning and multi-agent systems during the last twenty years. In this paper, we propose a new abstract framework where arguments are associated with a strength, namely a quantitative information which is used to determine whether an attack between arguments succeeds or not. Our Strength-based Argumentation Framework combines ideas of Preference-based and Weighted Argumentation Frameworks in an original way, which permits to define acceptability semantics sensitive to the existence of accruals between arguments. (...) The question of accruals arises in situations where several arguments defending the same position against another argument are unable to individually defeat this argument, but could do it collectively if they combine their strengths. We investigate some of the theoretical and computational properties of our new framework and semantics, and present a reasoning algorithm that is based on a translation of the problem into pseudo-boolean constraint satisfaction. This paper proposes an intuitive framework which allows strength compensations in an argumentation context where attacks may not succeed, completed by an approach which detects accruals throughout the reasoning process without requiring the elicitation of all compensatory combinations of arguments as an input.

Il dinamismo.--L'esistenzialismo.--La dialettica materialista.

El propósito del presente texto es mostrar, a contrapelo de lo que suelen sostener tanto sus detractores como sus abogados, que el neoliberalismo, en su crítica al keynesianismo y al Estado de bienestar, no pretende en absoluto reconducir el laissez-faire promovido por los marginalistas, aunque públicamente no tiene inconveniente en acomodarse de la retórica neoclásica. Antes bien, es consciente de que el libre mercado –por el que aboga– es algo que debe ser instituido y protegido frente a la inercia social; (...) y que, para ello, se precisa de un intervencionismo estatal que ampare el orden de la competencia, así como de un tejido institucional (escuela, prensa, cultura, etc.) que contribuya a la conformación de una subjetividad adaptada al carácter altamente evolutivo e incierto de la sociedad capitalista.

L’auteur donne quelques indications sur la théorie des ramifications qu’il a instituée.

This book is a treatise on cultural globalization and the global political economy. By introducing the transnational public domain in the study of China’s Belt and Road Initiative, the book goes beyond existing theoretical frameworks involving both the ‘clash between civilizations’ and the ‘time-worn division’ of the world into North and South. It advances a new focus on the theoretical and empirical elements that canvass global cultural behaviours and reactionary attitudes to the expanding Chinese economic norms, cultures and values in (...) different national contexts. Readers of political theory, global political economy, globalization, international relations, political sociology, cultural sociology, public policy and foreign policy analysis will find interest in the book. Whereas new nationalism couples with globalism, both concepts are rediscovered through various socio-economic contexts of BRI policy discourses, which produce conflicts, solidarities, new economic partnerships, and cooperation and resistance as types of contemporary nationalism. The new nationalism is approached as a dual-sided, relational, and dialectical phenomenon which readers will capture by paying particular attention to both the global and local scales of the social responses to the BRI.

Why does knowledge matter? Two answers have been influential in the recent literature. One is that it has value: knowledge is one of the goods. Another is that it plays a significant normative role: knowledge is the norm of action, belief, assertion, or the like. This paper discusses whether one can derive one of the claims from the other. That is, whether assuming the idea that knowledge has value — and some defensible general hypotheses about norms and values —, we (...) could derive the claim that it plays the alleged normative role. Or whether, assuming that knowledge does play that role — and some defensible general hypotheses —, we could derive the claim that it has value. It argues that the route from Value to Norms is unsuccessful. The main problem here is that the idea that knowledge has value does not seem enough to derive the idea that one should act on what one knows. It finds the route from Norms to Value more promising, though a complete path is missing. The main idea here is that knowledge is good because it is normatively required to do good things, such as believing the truth and acting in view of true propositions. But since not all normative conditions for doing something good is itself good, we still lack an explanation of why knowledge would be so. The paper finally suggests an alternative perspective, on which we do not try to derive the idea that knowledge has value from its normative role, but rather use its normative role to explain away the idea that it has value.

Taking our lead from Solomon’s emphasis on the importance of the intentional object of emotion, we review the history of repeated attempts to make this object disappear. We adduce evidence suggesting that in the case of James and Schachter, the intentional object got lost unintentionally. By contrast, modern constructivists seem quite determined to deny the centrality of the intentional object in accounting for the occurrence of emotions. Griffiths, however, downplays the role objects have in emotion noting that these do not (...) qualify as intentional. We argue that these disappearing acts, deliberate or not, generate fruitless debate and add little to the advancement of our understanding of emotion as an adaptive mechanism to cope with events that are relevant to an organism’s life.

The ethics of safe sex in the gay community has, for many years, been focused on debates surrounding the responsibility regarding the use of condoms to prevent HIV transmission, once the only tool available. With the development of Truvada as a pre-exposure prophylaxis for HIV, for the first time in the history of the HIV/AIDS epidemic there is the potential to significantly reduce the risk of HIV transmission during sex without the use of condoms. The introduction of PrEP necessitates a (...) renewed discussion about the politics and ethics of safe sex for men who have sex with men. We present the arguments of authors who hold radically opposite positions with regard to the ethics of condom use by gay men, but who currently both criticize the use of PrEP. We offer a critique of their arguments and advance the position that the use of PrEP, even without condoms, can be acceptable and part of a safe sex ethics framework for MSM. (shrink)

It is often argued that fully structural theories of truth and related notions are incapable of expressing a nonstratified notion of defectiveness. We argue that recently much-discussed non-contractive theories suffer from the same expressive limitation, provided they identify the defective sentences with the sentences that yield triviality if they are assumed to satisfy structural contraction.

Contextualist approaches to the Liar Paradox postulate the occurrence of a context shift in the course of the Liar reasoning. In particular, according to the contextualist proposal advanced by Charles Parsons and Michael Glanzberg, the Liar sentence L doesn’t express a true proposition in the initial context of reasoning c, but expresses a true one in a new, richer context c', where more propositions are available for expression. On the further assumption that Liar sentences involve propositional quantifiers whose domains may (...) vary with context, the Liar reasoning is blocked. But why should context shift? We argue that the paradox involves principles of contextualist reflection that explain, by analogy with well-known reflection principles for arithmetic, why context must shift from c to c' in the course of the Liar reasoning. This provides a diagnosis of the Liar Paradox—one that equally applies to two revenge arguments against contextualist approaches, one recently advanced by Andrew Bacon, the other mentioned by Charles Parsons and more recently revived by Cory Juhl.

In this paper, we contrast the different ways in which the representationalist and the attitudinalist in the theory of emotions account for the fact that emotions have evaluative correctness conditions. We argue that the attitudinalist has the resources to defend her view against recent attacks from the representationalist. To this end, we elaborate on the idea that emotional attitudes have a rich profile and explain how it supports the claim that these attitudes generate the wished-for evaluative correctness conditions. Our argument (...) rests on the idea that emotional attitudes manifest a sensitivity to evaluative evidence and that this sensitivity secures the kind of normativity we expect of the emotions. We bring our discussion to a close by assessing whether the psychological underpinnings of this sensitivity to evaluative evidence are such as to threaten the foundation of attitudinalism: the idea that emotions do not represent values. Given the available models of how we might access values prior to emotional experience, we conclude that the attitudinalist is still in the game. (shrink)

When spelled out properly infallibilism is a viable and even attractive view. Because it has long been summary dismissed, however, we need a guide on how to properly spell it out. The guide has to fulfil four tasks. The first two concern the nature of knowledge: to argue that infallible belief is necessary, and that it is sufficient, for knowledge. The other two concern the norm of belief: to argue that knowledge is necessary, and that it is sufficient, for justified (...) certainty. With such a guide in hand infallibilism can be evaluated on its own merits. The most controversial parts are the first and fourth. The idea that knowledge requires infallible belief is thought to be excessively sceptical. The idea that knowledge warrants certainty is thought to be excessively dogmatic. The present paper addresses the first. It argues that knowledge requires infallible belief. (shrink)
