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)

This is a Critical Notice for the general philosophical journal, Philosophy, of the anthology 'Many Worlds? Everett, Quantum Theory and Reality', edited by Simon Saunders, Jonathan Barrett, Adrian Kent and David Wallace.

Despite a growing body of literature focused on understanding experiences of workplace dignity, attention has centered almost exclusively on employees with lower-level jobs. As a result, little is known about how workplace dignity and indignity are experienced by employees with middle- and upper-level jobs and how their experiences differ from those with lower-level jobs. We address these absences by interviewing employees from a diversity of lower-, middle-, and upper-level jobs about their experiences of indignity at work. We outline common dignity (...) threats, along with typical emotional responses and recourses employees use at each level. We find lower-level employees experience chronic dignity threats from being disrespected, devalued, demeaned, and dehumanized, to which their most typical response is endurance. Middle-level employees experience periodic dignity threats due to undermining of their work, confidence, and reputation. For them, the typical response is strategizing. Finally, on the rare occasions upper-level employees experience dignity threats, it usually is due to a disregard of their special expertise or denial of special rights, to which they respond by rising above.

What would it mean to apply quantum theory, without restriction and without involving any notion of measurement and state reduction, to the whole universe? What would realism about the quantum state then imply? This book brings together an illustrious team of philosophers and physicists to debate these questions. The contributors broadly agree on the need, or aspiration, for a realist theory that unites micro- and macro-worlds. But they disagree on what this implies. Some argue that if unitary quantum evolution has (...) unrestricted application, and if the quantum state is taken to be something physically real, then this universe emerges from the quantum state as one of countless others, constantly branching in time, all of which are real. The result, they argue, is many worlds quantum theory, also known as the Everett interpretation of quantum mechanics. No other realist interpretation of unitary quantum theory has ever been found. Others argue in reply that this picture of many worlds is in no sense inherent to quantum theory, or fails to make physical sense, or is scientifically inadequate. The stuff of these worlds, what they are made of, is never adequately explained, nor are the worlds precisely defined; ordinary ideas about time and identity over time are compromised; no satisfactory role or substitute for probability can be found in many worlds theories; they can't explain experimental data; anyway, there are attractive realist alternatives to many worlds. Twenty original essays, accompanied by commentaries and discussions, examine these claims and counterclaims in depth. They consider questions of ontology - the existence of worlds; probability - whether and how probability can be related to the branching structure of the quantum state; alternatives to many worlds - whether there are one-world realist interpretations of quantum theory that leave quantum dynamics unchanged; and open questions even given many worlds, including the multiverse concept as it has arisen elsewhere in modern cosmology. A comprehensive introduction lays out the main arguments of the book, which provides a state-of-the-art guide to many worlds quantum theory and its problems. (shrink)

This article morally assesses alkaline hydrolysis as a means of final bodily disposition. Arguing from the Catholic social and theological principles of human dignity, the doctrine of bodily resurrection, subsidiarity, and the common good, the author shows that, while alkaline hydrolysis has some advantages over burial and cremation, Catholic conferences should be encouraged to resist its legalization, provided they focus renewed energy on teaching the faithful about the significance of Christ’s victory, by the Resurrection, over the corruption of bodily death.

The claim that the cult of Artemis of Ephesus included a rite of initiation, conducted by the kouretes, should be doubted. Various Ephesian magistrates in Roman Imperial times, but not the annual kouretes, declare that they celebrated “all the sacrifices and mysteries”. This however can be merely the increasingly pretentious terminology of the age, “mysteries” meaning no more than “holy rites”. Ancient authors show no knowledge of initiation to Artemis at Ephesus. In contrast, the inscriptions unambiguously attest initiation to Dionysus (...) and probably to Demeter, as we would expect in a Greek city. And in one dedication to Aphrodite, we do find again “mysteries”, but in this case metaphorical: they refer to marriage. (shrink)

Current computational models predict reward based solely on learning. Real motivation involves that but also more. Brain reward systems can dynamically generate incentive salience, by integrating prior learned values with even novel physiological states (e.g., natural appetites; drug-induced mesolimbic sensitization) to cause intense desires that were themselves never learned. We hope future computational models may capture this too.

The speaker of Demosthenes 56 had lent money to a ship-owner Dionysodorus for a commercial voyage, and now is prosecuting him for breach of contract. The prosecutor is usually thought to be a metic. In the course of the speech he does not identify himself; but Libanius in his Argumenta of Demosthenes supplies a name, Darius: Arg. 54.1 Δαρεῖος καὶ Πάμφιλος Διονυσοδώρῳ δανείζουσι and 2 ὡς δὲ Δαρεῖος λέγει. The manuscripts of the Argumenta, which begin in the tenth century, are (...) numerous; Foerster and Dindorf/Blass cite no variant for the name. Libanius’ source for this information is unrecoverable. (shrink)

In the course of his ethnography of Sicily, Thucydides gives this account of the settlement of Eryx and Egesta in the west of the island : Upon the fall of Troy, some of the Trojans, fleeing the Achaeans by ship, came to Sicily and settled as neighbours to the Sicans; as a group they were called Elymi, while their cities were called Eryx and Egesta. There joined with them in the settlement also some Phocians who were carried from Troy on (...) the same occasion first to Africa by a storm, later from there to Sicily. (shrink)

In the course of describing the events of the 160s b.c.e., 2 Maccabees presents the texts of four letters: the Seleucid general Lysias to the Jews granting some concessions and referring their other demands to the king ; two letters of Antiochus, to Lysias and to the Jews, granting various concessions; and Roman envoys to the Jews endorsing Lysias’ concessions. The third and fourth letters have at their ends the same date, 15 Xanthikos of Seleucid year 148, c. March 164 (...) b.c.e. The second has no date. The first, Lysias’ letter, is dated ἔτους ἑκατοστοῦ τεσσαρακοστοῦ ὀγδόου, διοσκορινθίου τετράδι καὶ εἰκάδι: year 148 on the 24th of a month; but the month name, standardly printed as Διὸς Κορινθίου, is impossible.

Psychopathy is a disorder characterized by severe and frequent moral violations in multiple domains of life. Numerous studies have shown psychopathy-related limbic brain abnormalities during moral processing; however, these studies only examined negatively valenced moral stimuli. Here, we aimed to replicate prior psychopathy research on negative moral judgments and to extend this work by examining psychopathy-related abnormalities in the processing of controversial moral stimuli and positive moral processing. Incarcerated adult males (N = 245) completed a functional magnetic resonance imaging protocol (...) on a mobile imaging system stationed at the prison. Psychopathy was assessed using the Hare Psychopathy Checklist–Revised (PCL-R). Participants were then shown words describing three types of moral stimuli: wrong (e.g., stealing), not wrong (e.g., charity), and controversial (e.g., euthanasia). Participants rated each stimulus as either wrong or not wrong. PCL-R total scores were correlated with not wrong behavioral responses to wrong moral stimuli, and were inversely related to hemodynamic activity in the anterior cingulate cortex in the contrast of wrong > not wrong. In the controversial > noncontroversial comparison, psychopathy was inversely associated with activity in the temporal parietal junction and dorsolateral prefrontal cortex. These results indicate that psychopathy-related abnormalities are observed during the processing of complex, negative, and positive moral stimuli. (shrink)

The Institutional Animal Care and Use Committee is entrusted with assessing the ethics of proposed projects prior to approval of animal research. The role of the IACUC is detailed in legislation and binding rules, which are in turn inspired by the Three Rs: the principles of Replacement, Reduction, and Refinement. However, these principles are poorly defined. Although this provides the IACUC leeway in assessing a proposed project, it also affords little guidance. Our goal is to provide procedural and philosophical clarity (...) to the IACUC without mandating a particular outcome. To do this, we analyze the underlying logic of the Three Rs and conclude that the Three Rs accord animals moral standing, though not necessarily “rights” in the philosophical sense. We suggest that the Rs are hierarchical, such that Replacement, which can totally eliminate harm, should be considered prior to Reduction, which decreases the number of animals harmed, with Refinement being considered last. We also identify the need for a hitherto implicit fourth R: Reject, which allows the IACUC to refuse permission for a project which does not promise sufficient benefit to offset the pain and distress likely to be caused by the proposed research.

Behavior, language, development, identity, and science—all of these phenomena are commonly characterized as 'social' in nature. But what does it mean to be 'social'? Is there any intrinsic 'mark' of the social shared by these phenomena? In the first book to shed light on this foundational question, twelve distinguished philosophers and social scientists from several disciplines debate the mark of the social. Their varied answers will be of interest to sociologists, anthropologists, philosophers, psychologists, and anyone interested in the theoretical foundations (...) of the social sciences. (shrink)
