© 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)

I develop a theory of counterfactuals about relative computability, i.e. counterfactuals such as 'If the validity problem were algorithmically decidable, then the halting problem would also be algorithmically decidable,' which is true, and 'If the validity problem were algorithmically decidable, then arithmetical truth would also be algorithmically decidable,' which is false. These counterfactuals are counterpossibles, i.e. they have metaphysically impossible antecedents. They thus pose a challenge to the orthodoxy about counterfactuals, which would treat them as uniformly true. What’s more, I (...) argue that these counterpossibles don’t just appear in the periphery of relative computability theory but instead they play an ineliminable role in the development of the theory. Finally, I present and discuss a model theory for these counterfactuals that is a straightforward extension of the familiar comparative similarity models. (shrink)

The Greek word eoikos can be translated in various ways. It can be used to describe similarity, plausibility or even suitability. This book explores the philosophical exploitation of its multiple meanings by three philosophers, Xenophanes, Parmenides and Plato. It offers new interpretations of the way that each employs the term to describe the status of their philosophy, tracing the development of this philosophical use of eoikos from the fallibilism of Xenophanes through the deceptive cosmology of Parmenides to Plato's Timaeus. The (...) central premise of the book is that, in reflecting on the eoikos status of their accounts, Xenophanes, Parmenides and Plato are manipulating the contexts and connotations of the term as it has been used by their predecessors. By focusing on this continuity in the development of the philosophical use of eoikos, the book serves to enhance our understanding of the epistemology and methodology of Xenophanes, Parmenides and Plato's Timaeus.

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

Boorse’s biostatistical theory states that diseases should be defined in ways that reflect disturbances of biological function and that are objective and value free. We use three examples from contemporary medicine that demonstrate the complex issues that arise when defining the boundaries of disease: polycystic ovary syndrome, chronic kidney disease, and myocardial infarction. We argue that the biostatistical theory fails to provide sufficient guidance on where the boundaries of disease should be drawn, contains ambiguities relating to choice of reference class, (...) and is out of step with medical processes for identifying disease boundaries. Although proponents of the biostatistical theory might regard these practical issues as irrelevant to the aim of providing a theoretical account of disease, we take them to indicate the need for a theoretical account that is adequate for current needs—including limiting new forms of medicalization that are driven by the identification of disease based on dysfunction. Our processes for determining the boundaries for disease need to recognize that there is no value-free method for making these decisions. (shrink)

The aim of this thematic literature review is to explore nurses' perceptions of ethical issues in the care of older people. Electronic databases were searched from September 1997 to September 2007 using specific key words with tight inclusion criteria, which revealed 17 primary research reports. The data analysis involved repeated reading of the findings and sorting of those findings into four themes. These themes are: sources of ethical issues for nurses; differences in perceptions between nurses and patients/relatives; nurses' personal responses (...) to ethical issues; and the patient—nurse relationship. The findings reveal that ageism is one of the major sources of the ethical issues that arise for nurses caring for older people. Education and organizational change can combat ageist attitudes. Wider training is required in the care of older people, workplace skills, palliative care and pain management for older people. The demands of a changing global demography will necessitate further research in this field. (shrink)

The recent philosophy of Quantum Bayesianism, or QBism, represents an attempt to solve the traditional puzzles in the foundations of quantum theory by denying the objective reality of the quantum state. Einstein had hoped to remove the spectre of nonlocality in the theory by also assigning an epistemic status to the quantum state, but his version of this doctrine was recently proved to be inconsistent with the predictions of quantum mechanics. In this essay, I present plausibility arguments, old and new, (...) for the reality of the quantum state, and expose what I think are weaknesses in QBism as a philosophy of science. (shrink)

James Frederick Ferrier James Frederick Ferrier was a mid-nineteenth-century Scottish metaphysician who developed the first post-Hegelian system of idealism in Britain. Unlike the British Idealists in the latter half of the nineteenth century, he was neither a Kantian nor a Hegelian. Instead, he largely develops his idealist metaphysics via his defense of Berkeley and … Continue reading Ferrier, James Frederick →.

Ancient Greek and Roman philosophy is often characterised in terms of competitive individuals debating orally with one another in public arenas. But it also developed over its long history a sense in which philosophers might acknowledge some other particular philosopher or group of philosophers as an authority and offer to that authority explicit intellectual allegiance. This is most obvious in the development after the classical period of the philosophical 'schools' with agreed founders and, most importantly, canonical founding texts. There also (...) developed a tradition of commentary, interpretation, and discussion of texts which itself became a mode of philosophical debate. As time went on, the weight of a growing tradition of reading and appealing to a certain corpus of foundational texts began to shape how later antiquity viewed its philosophical past and also how philosophical debate and inquiry was conducted. In this book leading scholars explore aspects of these important developments. (shrink)

It has become increasingly clear that social learning and culture occur much more broadly, and in a wider variety of animal communities, than initially believed. Recent research has expanded the list to include insects, fishes, elephants, and cetaceans. Such diversity allows scientists to expand the scope of potential research questions, which can help form a more complete understanding of animal culture than any single species can provide on its own. It is crucial to understand how culture and social learning present (...) in different communities, as well as what influences community structure and culture may have on one another, so that the results across these different studies may most effectively inform one another. This review presents an overview of social learning in species across a spectrum of community structures, providing the necessary infrastructure to allow a comparison of studies that will help move the field of animal culture forward.

People frequently gesture when a word is on the tip of their tongue (TOT), yet research is mixed as to whether and why gesture aids lexical retrieval. We tested three accounts: the lexical retrieval hypothesis, which predicts that semantically related gestures facilitate successful lexical retrieval; the cognitive load account, which predicts that matching gestures facilitate lexical retrieval only when retrieval is hard, as in the case of a TOT; and the motor movement account, which predicts that any motor movements should (...) support lexical retrieval. In Experiment 1 (a between‐subjects study; N = 90), gesture inhibition, but not neck inhibition, affected TOT resolution but not overall lexical retrieval; participants in the gesture‐inhibited condition resolved fewer TOTs than participants who were allowed to gesture. When participants could gesture, they produced more representational gestures during resolved than unresolved TOTs, a pattern not observed for meaningless motor movements (e.g., beats). However, the effect of gesture inhibition on TOT resolution was not uniform; some participants resolved many TOTs, while others struggled. In Experiment 2 (a within‐subjects study; N = 34), the effect of gesture inhibition was traced to individual differences in verbal, not spatial short‐term memory (STM) span; those with weaker verbal STM resolved fewer TOTs when unable to gesture. This relationship between verbal STM and TOT resolution was not observed when participants were allowed to gesture. Taken together, these results fit the cognitive load account; when lexical retrieval is hard, gesture effectively reduces the cognitive load of TOT resolution for those who find the task especially taxing.

What am I? There are a number of possible answers: I am a person, a mind, a human animal, a soul, part of a human being (e.g., a brain), I do not exist, and even more. Philosophers have been asking this for thousands of years and were not satisfied. In the contemporary analytic tradition, philosophers are attracted to a naturalistic, scientific ontology hence a materialistic personal ontology that matches the huge success in scientific discoveries. They think that we are material (...) objects. However, their views do not match our intuition about some cases regarding our survival. Also, the possibility of an afterlife is eliminated. In my thesis, I explain the shortcomings of current philosophical theories, and develop a better account. I propose the Conscious Subject View, according to which (1) I am a subject of experience, a mental entity whose essential property is to be conscious, and (2) Subjects have haecceities, a property that makes an object a different object from other objects even if they are qualitatively identical with it. I provide two arguments for the claim that we are essentially subjects. The first is the Essentiality Argument. I first define an egoistic concern as one such that necessarily, my concern about X can be egoistic if and only if I exist and persist as X. Furthermore, I argue that necessarily, I can be egoistically concerned with an entity E if and only if E is numerically identical with my subject of experience. I then conclude that we are essentially subjects of experience. My second argument, which I call the Argument of Persistence, is that we have the intuition that we persist only when there is the gradual replacement of the brain. I argue that the best candidate to explain this intuition is that we persist as subjects of experience. I further offer a conceivability argument for the claim that haecceity of the subject determines its persistence. I defend a mentally-oriented proposal regarding our nature by examining the essential properties of our existence. It solves most of the problems with the materialistic personal ontology and shows the theoretical advantages of a long-neglected approach. (shrink)

In the last few years, justice has emerged as a matter of concern for the contemporary constitution of technoscience. Increasingly, both practicing scientists and engineers and scholars of science and technology cite justice as an organizing theme of their work. In this essay, I consider why “science and justice” might be arising now. I then ask after the opportunities, but also the dangers, of this formation. By way of example, I explore the openings and exclusions created by the recent conjugation (...) of science and justice in the field of personal genomics. Finally, I conclude with reflections on what other forms “science and justice” might take, and what might be gained or lost in fostering them. (shrink)

Algorithms wield increasing control over our lives—over which jobs we get, whether we're granted loans, what information we're exposed to online, and so on. Algorithms can, and often do, wield their power in a biased way, and much work has been devoted to algorithmic bias. In contrast, algorithmic neutrality has gone largely neglected. I investigate three questions about algorithmic neutrality: What is it? Is it possible? And when we have it in mind, what can we learn about algorithmic bias?

In this essay, I argue that to create a genomics that offers more gifts than weights, central attention must be paid to questions of justice. This will require expanding bioethical imaginations so that they grasp and can respond to questions of structural inequity. It will necessitate building novel coalitions and collaborations that turn the attention of bioethical governance away from narrow individual questions such as, “Do I consent?” and toward the broader collective question, is this just? What kind of lives (...) and collectivities are made possible? What rights and principles should govern them? The essay ends with one example of this novel coalition building arising from the Science and Justice Research Center at the University of California, Santa Cruz. It draws lessons from this effort to build new alliances that bridge the social sciences and natural sciences, arts and engineering, to create new kinds of training and thinking that create a genomics that more adequately responds to fundamental questions of justice.

Written for English-speaking readers, it describes the varied traditions within 19th- and 20th-century European philosophy, reflecting the dynamism and plurality within the European tradition and presenting opposing points of view. It deals with both French and German philosophers, plus Kierkegaard, and is not (...) confined to any one school of thought. It has been purged of jargon but contains a glossary of important technical terms. There is a bibliography of further reading and website information at the end of each chapter. (shrink)

Our daily experience, dominated by the corporate clock that so many of us contort ourselves to fit inside, is destroying us. It wasn't built for people, it was built for profit. This is a book that tears open the seams of reality as we know it-the way we experience time itself-and rearranges it, reimagining a world not centered around work, the office clock, or the profit motive. Explaining how we got to the point where time became money, Odell offers us (...) new models to live by--inspired by pre-industrial cultures, ecological, and geological time--that make a more humane, more hopeful way of living seem possible. In this dazzling, subversive, and deeply hopeful reframing of time, Jenny Odell takes us on a journey through other temporal habitats. As planet-bound animals, we live inside shortening and lengthening days, alongside gardens growing, birds migrating, and cliffs eroding. The stretchy quality of waiting and desire, the way the present may suddenly feel marbled with childhood memory, the slow but sure procession of a pregnancy, or the time it takes to heal from injuries--physical or emotional. Odell urges us to become stewards of these different rhythms of life, to imagine a life, identity, and source of meaning outside of the world of work and profit, and to understand that the trajectory of our lives--or the life of the planet--is not a foregone conclusion. In that sense, "saving" time-recovering its fundamentally irreducible and inventive nature-could also mean that time saves us. (shrink)

Does the real difference between non-consequentialist and consequentialist theories lie in their approach to value? Non-consequentialist theories are thought either to allow a different kind of value (namely, agent-relative value) or to advocate a different response to value ('honouring' rather than 'promoting'). One objection to this idea implies that all normative theories are describable as consequentialist. But then the distinction between honouring and promoting collapses into the distinction between relative and neutral value. A proper description of non-consequentialist theories can only (...) be achieved by including a distinction between temporal relativity and neutrality in addition to the distinction between agent-relativity and agent-neutrality.

The core idea of social constructivism in mathematics is that mathematical entities are social constructs that exist in virtue of social practices, similar to more familiar social entities like institutions and money. Julian C. Cole has presented an institutional version of social constructivism about mathematics based on John Searle’s theory of the construction of the social reality. In this paper, I consider what merits social constructivism has and examine how well Cole’s institutional account meets the challenge of accounting for the (...) characteristic features of mathematics, especially objectivity and applicability. I propose that in general social constructivism shows promise as an ontology of mathematics, because the view can agree with mathematical practice and it offers a way of understanding how mathematical entities can be real without conflicting with a scientific picture of reality. However, I argue that Cole’s specific theory does not provide an adequate social constructivist account of mathematics. His institutional account fails to sufficiently explain the objectivity and applicability of mathematics, because the explanations are weakened and limited by the three-level theoretical model underlying Cole’s account of the construction of mathematical reality and by the use of the Searlean institutional framework. The shortcomings of Cole’s theory give reason to suspect that the Searlean framework is not an optimal way to defend the view that mathematical reality is socially constructed. (shrink)

The frequency and severity of natural disasters and extreme weather events are increasing, taking a dramatic economic and relational toll on the communities they strike. Given the critical role that entrepreneurship plays in a community’s viability, it is necessary to understand how small business owners respond to these events and move forward over time. This study explores the long-term dynamics and trajectory of individuals within the broader business community following a natural disaster, paying particular attention to the influence of social (...) identity. Results suggest that the community identity changes over the course of recovery and rebuilding, underscoring the need for a holistic approach so that intervening agencies can achieve the sustainable economic recovery desired.

What Is Race? Evidence from Scientists is a picture book for schoolchildren published by UNESCO as part of its high-profile campaign on race. The 87-page, oblong, soft-cover booklet contains bold, semi-abstract, pared-down images accompanied by text, devised to make scientific concepts ‘more easily intelligible to the layman’. Produced by UNESCO’s Department of Mass Communication, the picture book represents the organization’s early-postwar confidence in the power of scientific knowledge as a social remedy and diplomatic tool. In keeping with a significant component (...) of the race campaign, What Is Race? presented genetics as the route to an enlightened, scientific, non-prejudiced understanding of race. This article seeks to explain the book’s management, aesthetics and framing in the context of postwar disciplinary and international politics. Viewing UNESCO’s race campaign as a high point for an internationalist ideology of mass education, this article also analyses the visual and literary arguments of What Is Race? and proposes that the enduring image of genetics as technical and neutral knowledge was in part shaped by UNESCO’s efforts to communicate scientific authority to an apparently ‘popular’ audience.
