© 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)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

This book explores the role of aggression in primate social systems and its implications for human behavior.

It is still commonly supposed that Descartes based his argument for the mind-body distinction on the law of the indiscernibility of identicals. I argue that this interpretation is very unlikely to be correct. I explain three contemporary versions of this interpreta- tion and say why I reject it. Basically, use of this law for Descartes’s conclusion would require reference to human bodies or else the supposition, for the purpose of the argument, of reference to human bodies. But at the time (...) Descartes formulated his argument, he would not have allowed either. Instead, I amend a different interpretation which others have found, and briefly defend it against one famous objection. (shrink)

An examination of Russia's philosophical heritage. It extends from the Slavophiles to the philosophers of the Silver Age, from emigre religious thinkers to Losev and Bakhtin and assesses the meaning for Russian culture as a whole.

Systemism and social mechanisms, as articulated by Bunge, are concepts with great potential for application to assessment of research progress. This study will use the conceptual tools made available by systemism and social mechanisms to evaluate the International Crisis Behavior (ICB) Project as a scientific effort toward the greater understanding of crises in world politics. Systemism and social mechanisms are articulated as key concepts in the quest for scientific progress. The goals and basic characteristics of the ICB Project as a (...) scientific venture then are described. The ICB Project is assessed in terms of how well it lives up to standards for scientific progress. Finally, conclusions and ideas about future research are presented. The basic finding of this study is that the ICB Project is quite successful in meeting the standards for scientific progress entailed by the concepts of systemism and social mechanisms. Key Words: scientific progress • international relations • international crises • paradigm. (shrink)

In the conventional analysis of human behaviour, power and ethics are frequently considered contrary principles, in that power enforces, while ethics elicits a free response. But, as James Mackey forcefully shows, a more adventurous philosophical study of human morality escapes the sense of contraries, and sets us on a quest for the kind of power that liberates human creativity. It then becomes possible to establish the framework for a critical assessment of the kind of power that ought to be (...) operative in the major structures of human society, civil or ecclesiastical, state governments and church hierarchies. Mackey analyses the religious question which then quite naturally emerges, as to whether this Eros-type power so manifest in human society originates from beyond the more empirical structures of churches, states and 'nature'; and the effort to detect the specifically Christian characterisation of an allegedly ultimate power working in us for final well-being finds its natural context.

Clement Dore has offered a demonstration that God is possible. This is important because the Ontological Argument shows that if God is possible, it is necessarily true that God exists. Dore’s demonstration parallels Descartes’s Meditation V argument: (roughly) God by definition has all perfections; but (Dore proposes) possible existence is a perfection; therefore, God is possible. However, Leibniz recognized that Descartes’s argument is incomplete, omitting proof that the concept of God is consistent. Dore’s demonstration fails for just this reason. Dore’s (...) defense misses this objection. If the concept of God is consistent, that directly establishes that God is possible, making assumptions about perfections irrelevant. (shrink)

Far from merely reinvigorating relativism, postmodernism has detected and expressed in our time a powerful nihilating process of which truth and reality itself are the final casualties; and with these morality and religion. Beginning from the theological reaches of philosophy, this book argues that gods played a crucial part in modern philosophy, even when it was most critical of them; that the dominant nihilism of Derrida is really an excessive and misleading outcome of a contemporary philosophy which could otherwise resonate (...) with all that is best in our evolutionary image of the universe; that moralists who turn to art in order to overcome the fact-value version of this deadly dualism do not thereby rule out religion; and that a Christian theology which recognises the evolutionary/historical conditions of faith and revelation is once again producing a theology that builds upon the best of contemporary philosophy and science.

Donald R. Gregory has recently argued that the monk Gaunilo's response to St Anselm's ontological argument succeeds in showing what is fundamentally wrong with any ontological argument, including modern modal versions. He holds that the Gaunilo strategy in fact demonstrates what it alleges, that reasoning which parallels the form and intent ofAnselm's reductio argument can ‘prove’ a priori the existence of quite unacceptable entities.

In lieu of an abstract, here is a brief excerpt of the content:The Case against Rational Egoism in Dostoevsky’s Notes from Underground*James P. ScanlanWriting in his own voice, in letters, notebooks, and diaries, Fyodor Dostoevsky frequently attacked the philosophy of the Russian “nihilists,” as he typically called them—Nikolay Chernyshevsky, Dmitry Pisarev, and other representatives of the radical Russian intelligentsia in the third quarter of the nineteenth century. But because Dostoevsky also used fiction to argue against them, if we wish (...) to discern the full contours of his opposition, we must turn to his stories and novels; and there we face the problem of determining to what extent, if any, the statements of his narrators and characters express his own views.This problem is particularly challenging in regard to the radicals’ “Rational Egoism,” to use the label by which the Russian variant of the theory of enlightened egoism came to be known. 1 Dostoevsky’s most sustained and spirited attack on that aspect of “nihilist” philosophy is found in Part One of Notes from Underground (1864), but it is voiced by one of the darkest, least sympathetic of all his characters—the nameless narrator and protagonist known as the Underground Man. Was this repellent creature speaking for Dostoevsky? The Underground Man, moreover, can easily be viewed as a sheer irrationalist whose rejection of Rational Egoism is a tortured emotional outburst with no logical credentials. Robert L. Jackson, in his groundbreaking study of 1958, describes the Underground Man’s thinking at one point as follows: “It is impossible to argue [End Page 549] with the rationalists: reason is on their side. All that remains is irrationally to negate reason.” 2 If those words were to be taken not simply as a moment in Jackson’s rich analysis but as a comprehensive description of the Underground Man’s attitude, it would be senseless to expect philosophically nuanced arguments from him. And we would have no grounds for thinking that Dostoevsky’s own treatment of Rational Egoism went beyond emotional rejection.Critics from Vasily Rozanov to Joseph Frank have debated the Underground Man’s stance toward Rational Egoism and its relation to Dostoevsky’s, with no sign yet of a definitive resolution. Frank’s recent treatment, presented in the third volume of his monumental literary biography of Dostoevsky, offers a helpful history of the dispute as well as his own finely elaborated interpretation of the Underground Man as an irrational opponent of Rational Egoism. 3 Frank reads Notes from Underground as satire, and he contends that the Underground Man is caught in an agonizing self-contradiction: intellectually, he accepts the basic premises of the Rational Egoists’ outlook, such as the denial of free will; but he finds that, “despite the convictions of his reason,” he cannot live with the amoral and dehumanizing implications of those premises, which strip human beings of moral responsibility. 4 From a rational point of view, of course, rejection of the implications should force the Underground Man to reject the premises as well (by the hoary logical law of modus tollendo tolens), and indeed he does at times passionately condemn them. But according to Frank, these condemnations simply show the depth of his predicament: his “intellectual acceptance” of Chernyshevsky’s determinism is conjoined with “simultaneous rejection of it with the entire intuitive-emotional level of personality identified with moral conscience,” causing him to respond irrationally in a multitude of instances. 5 Frank’s Underground Man, then, is an intellectual disciple but an emotional critic of Rational Egoism; and he is triply an irrationalist: his thinking is mired in self-contradiction, he acts irrationally as a result, and his opposition to Rational Egoism has not a rational but an “intuitive-emotional” basis.But where does this leave Dostoevsky? Must we conclude that he, too, is somehow suspended between acceptance and rejection of Rational Egoism and for that reason has created in Notes from Underground a Bakhtinian equilibrium in which neither position is clearly privileged? For Frank, certainly not. It follows from Frank’s analysis that Dostoevsky himself, unlike the Underground [End Page 550] Man, is a fully consistent opponent of Rational Egoism, for that theory is the target of the inverted irony at the core of his satire; “the...

This article presents texts recovered by post-processing of multispectral images from the fifth- or sixth-century underwriting of the palimpsest Codex Climaci Rescriptus. Texts identified include the Anonymous II Proemium to Aratus’ Phaenomena, parts of Eratosthenes’ Catasterisms, Aratus’ Phaenomena lines 71–4 and 282–99 and previously unknown text, including some of the earliest astronomical measurements to survive in any Greek manuscript. Codex Climaci Rescriptus also contains at least three astronomical drawings. These appear to form part of an illustrated manuscript, with considerable textual (...) value not merely on the basis of its age but also of its readings. The manuscript undertexts show significant overlap with the Φ Edition, postulated as ancestor of the various Latin Aratea. (shrink)

We review an argument that proposes two moralities—“everyday” moral norms and “adversarial” moral norms—are required for business contexts. We take issue with an implication of this idea, namely that competitive actions do not need to be in accord with “everyday” moral norms. After showing that the argument for two moralities in business does not succeed, we propose a distinction between two types of competitive actions: principled, those actions which comport with every day morality, and merely self-interested, those actions that do (...) not comport with every day morality. The merits of this distinction are discussed. (shrink)

The experience of causation is a pervasive product of the human mind. Moreover, the experience of causing an event alters subjective time: actions are perceived as temporally shifted towards their effects [Haggard, P., Clark, S., & Kalogeras, J.. Voluntary action and conscious awareness. Nature Neuroscience, 5, 382-385]. This temporal shift depends partly on advance prediction of the effects of action, and partly on inferential "postdictive" explanations of sensory effects of action. We investigated whether a single factor of statistical contingency could (...) explain both these aspects of causal experience. We studied the time at which people perceived a simple manual action to occur, when statistical contingency indicated a causal relation between action and effect, and when no such relation was indicated. Both predictive and inferential "postdictive" shifts in the time of action depended on strong contingency between action and effect. The experience of agency involves a process of causal learning based on statistical contingency. (shrink)

This paper is an investigation of the relationship between G\"odel's second incompleteness theorem and the well-foundedness of jump hierarchies. It follows from a classic theorem of Spector's that the relation $\{(A,B) \in \mathbb{R}^2 : \mathcal{O}^A \leq_H B\}$ is well-founded. We provide an alternative proof of this fact that uses G\"odel's second incompleteness theorem instead of the theory of admissible ordinals. We then derive a semantic version of the second incompleteness theorem, originally due to Mummert and Simpson, from this result. Finally, (...) we turn to the calculation of the ranks of reals in this well-founded relation. We prove that, for any $A\in\mathbb{R}$, if the rank of $A$ is $\alpha$, then $\omega_1^A$ is the $(1 + \alpha)^{\text{th}}$ admissible ordinal. It follows, assuming suitable large cardinal hypotheses, that, on a cone, the rank of $X$ is $\omega_1^X$. (shrink)

We investigate the processes underlying the feeling of control over one’s actions . Sense of agency may depend on internal motoric signals, and general inferences about external events. We used priming to modulate the sense of agency for voluntary and involuntary movements, by modifying the content of conscious thought prior to moving. Trials began with the presentation of one of two supraliminal primes, which corresponded to the effect of a voluntary action participants subsequently made. The perceived interval between movement and (...) effect was used as an implicit measure of sense of agency. Primes modulated perceived intervals for both voluntary and involuntary movements, but the modulation was greatest for involuntary movements. A second experiment showed that this modulation depended on prime–movement contiguity. We propose that sense of agency is based on a combination of internal motoric signals and external sensory evidence about the source of actions and effects. (shrink)

The emergence of shared symbol systems is considered to be a pivotal moment in human evolution and human development. These changes are normally explained by reference to changes in people's internal cognitive processes. We present 2 experiments which provide evidence that changes in the external, collaborative processes that people use to communicate can also affect the structure and organization of symbol systems independently of cognitive change. We propose that mutual‐modifiability—opportunities for people to edit or manipulate each other's contributions—is a key (...) constraint on the emergence of complex symbol systems. We discuss the implications for models of language development and the origins of compositionality. (shrink)

This essay examines asset development for the poor as an approach to reducing poverty. Because there has been very little discussion of this approach by Christian ethicists, my primary purpose is to introduce and defend the rationale for developing assets for the poor. I begin with a discussion of conservative and liberal approaches to poverty reduction, arguing that the favored policies of both are founded upon the belief that poverty is best understood as a state of consumption deprivation brought on (...) by deficient levels of income. I suggest that the focus on consumption and income, while obviously important in light of the material deprivations of the poor, is not in itself a sufficient response to the needs of the poor. This leads to a discussion of past and present public policies that have stimulated asset development. A characteristic feature of many of these policies is that they have provided both material and institutional support for asset development, but only for the nonpoor. If public policies have helped the nonpoor to save, why should we not develop policies that help the poor do the same? Some suggested approaches to developing assets for the poor are then reviewed. Finally, I briefly discuss points of convergence between Catholic social thought and asset-development approaches to poverty reduction. (shrink)

Examines the perennial issues that keep science and religion at arm's length, clarifies those issues, and fits them into an historical framework—from Plato, to Aquinas, to today's thinkers.

Historical narratives can satisfy basic individual psychological needs. However, an over-reliance on a group's past can marginalize those who think differently – thus, homogenizing the culture and stifling creativity. By revising narratives to balance the power of collective narratives with the richness of individuality, we foster groups that encourage varied identities.

This book is a rebuttal of the common charge that the moral doctrine of utilitarianism permits horrible acts, justifies unfair distribution of wealth and other social goods, and demands too much of moral agents. Bailey defends utilitarianism by applying central insights of game theory regarding feasible equilibria and evolutionary stability of norms to elaborate an account of institutions that real-world utilitarians would want to foster. With such an account he shows that utilitarianism, while still a useful doctrine for criticizing (...) existing institutions, is far more congruent with ordinary moral common sense than has been generally recognized. A controversial attempt to support the practical use of utilitarian ethics in a world of conflicting interests and competing moral agents, Bailey's work uniquely bridges the abstract debate of philosophers and the practical, consequence-based debates of political scientists.

This paper describes what could be labeled “best practices” in teaching ethics to those entering the criminal justice, criminology and related professional fields. The underlying focus of the discussion is on the “self” and reflects the beliefs of the authors in the pedagogic thesis that ethics awareness begins with individual social actors and their existing world views. Thereafter, self awareness of ethical dilemmas and internal safeguards against unethical behavior are defined by those same individuals. Lastly, the process continues when the (...) social actor gains an internalized, self-generated, accountability for one’s own actions. That self accountability may morph over time, depending on circumstances, but individual social actors remain effectively protected from unethical behavior as they master their own ethical challenges and live within their individualized sense of ethical purpose. To make these arguments the authors describe the background for an effective learning paradigm for the study of ethics that can be used in university level criminal justice courses, criminology classes, and police training sessions. This pedagogic approach is theoretically informed and used in classes designed to teach ethics to criminal justice professionals, criminology students who are entering a variety of professions.
