© 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)

"Understanding Scientific Progress constitutes a potentially enormous and revolutionary advancement in philosophy of science. It deserves to be read and studied by everyone with any interest in or connection with physics or the theory of science. Maxwell cites the work of Hume, Kant, J.S. Mill, Ludwig Bolzmann, Pierre Duhem, Einstein, Henri Poincaré, C.S. Peirce, Whitehead, Russell, Carnap, A.J. Ayer, Karl Popper, Thomas Kuhn, Imre Lakatos, Paul Feyerabend, Nelson Goodman, Bas van Fraassen, and numerous others. He lauds Popper for (...) advancing beyond verificationism and Hume’s problem of induction, but faults both Kuhn and Popper for being unable to show that and how their work could lead nearer to the truth." —Dr. LLOYD EBY teaches philosophy at The George Washington University and The Catholic University of America, in Washington, DC "Maxwell's aim-oriented empiricism is in my opinion a very significant contribution to the philosophy of science. I hope that it will be widely discussed and debated." – ALAN SOKAL, Professor of Physics, New York University "Maxwell takes up the philosophical challenge of how natural science makes progress and provides a superb treatment of the problem in terms of the contrast between traditional conceptions and his own scientifically-informed theory—aim-oriented empiricism. This clear and rigorously-argued work deserves the attention of scientists and philosophers alike, especially those who believe that it is the accumulation of knowledge and technology that answers the question."—LEEMON McHENRY, California State University, Northridge "Maxwell has distilled the finest essence of the scientific enterprise. Science is about making the world a better place. Sometimes science loses its way. The future depends on scientists doing the right things for the right reasons. Maxwell's Aim-Oriented Empiricism is a map to put science back on the right track."—TIMOTHY McGETTIGAN, Professor of Sociology, Colorado State University - Pueblo "Maxwell has a great deal to offer with these important ideas, and deserves to be much more widely recognised than he is. Readers with a background in philosophy of science will appreciate the rigour and thoroughness of his argument, while more general readers will find his aim-oriented rationality a promising way forward in terms of a future sustainable and wise social order."—David Lorimer, Paradigm Explorer, 2017/2 "This is a book about the very core problems of the philosophy of science. The idea of replacing Standard Empiricism with Aim-Oriented Empiricism is understood by Maxwell as the key to the solution of these central problems. Maxwell handles his main tool masterfully, producing a fascinating and important reading to his colleagues in the field. However, Nicholas Maxwell is much more than just a philosopher of science. In the closing part of the book he lets the reader know about his deep concern and possible solutions of the biggest problems humanity is facing."—Professor PEETER MŰŰREPP, Tallinn University of Technology, Estonia “For many years, Maxwell has been arguing that fundamental philosophical problems about scientific progress, especially the problem of induction, cannot be solved granted standard empiricism (SE), a doctrine which, he thinks, most scientists and philosophers of science take for granted. A key tenet of SE is that no permanent thesis about the world can be accepted as a part of scientific knowledge independent of evidence. For a number of reasons, Maxwell argues, we need to adopt a rather different conception of science which he calls aim-oriented empiricism (AOE). This holds that we need to construe physics as accepting, as a part of theoretical scientific knowledge, a hierarchy of metaphysical theses about the comprehensibility and knowability of the universe, which become increasingly insubstantial as we go up the hierarchy. In his book “Understanding Scientific Progress: Aim-Oriented Empiricism”, Maxwell gives a concise and excellent illustration of this view and the arguments supporting it… Maxwell’s book is a potentially important contribution to our understanding of scientific progress and philosophy of science more generally. Maybe it is the time for scientists and philosophers to acknowledge that science has to make metaphysical assumptions concerning the knowability and comprehensibility of the universe. Fundamental philosophical problems about scientific progress, which cannot be solved granted SE, may be solved granted AOE.” Professor SHAN GAO, Shanxi University, China . (shrink)

Arguments for feature creation receive support from studies of young infants forming category representations from perceptual experience. A challenge for Schyns et al. will be to determine how a feature creation system might interface with a perceptual system that appears constrained to follow organizational principles that specify how edge segments should be grouped into functional units of coherent object representations.

We use the Drozd-Warfield structure theorem for finitely presented modules over a serial ring to investigate the model theory of modules over a serial ring, in particular, to give a simple description of pp-formulas and to classify the pure-injective indecomposable modules. We also study the question of whether every pure-injective indecomposable module over a valuation ring is the hull of a uniserial module.

This research compares the importance of moral values for corporations' managements, as reported by 97 knowledgeable employees in eight corporations. Does an employee consensus emerge within corporations and does it differ between corporations? To answer this question, an analysis of covariance technique was used to compare the importance of moral values between corporations versus within corporations. Results corroborate the hypothesis that closely matched corporations do differ significantly from one another in the importance of prevailing moral values. Evidence also suggests that (...) the importance of prevailing moral values may be inversely related with company size. Implications for future research and for the practice of management are delineated. (shrink)

Paul C. Taylor provides an accessible guide to a well-travelled but still-mysterious area of the contemporary social landscape. The result is the first philosophical introduction to the field of race theory and to a non-biological and situational notion of race. Provides the first philosophical introduction to the field of race theory. Outlines the main features and implications of race-thinking; asks questions such as: What is race-thinking? Don’t we know better than to talk about race now? Are there any races? (...) What is it like to have a racial identity? Engages with the ideas of such important figures as Linda Alcoff, K. Anthony Appiah, W.E.B. Du Bois, Howard Winant, and Naomi Zack. Explores the enduring significance of race in relation to culture, personal relationships and social justice. (shrink)

In this paper I shall argue that useful correspondences can be drawn between the role of depiction in showing a view of the world and the realisation that would view God as a picture of experience in the world, since both can be seen to illustrate an art of interpretation. The perceptual insight that is gleaned in mystical-philosophical consciousness converges on the idea of a realm that is marked as divine, and by exploiting mental and linguistic imagery this mindful awareness (...) can be made concrete in the form of a written text, which can be seen to be analogous to a pictorial representation. The writer of a text purportedly sees and knows the domain of divine reality through sensible and conceptual means and then reduces this consciousness to a planar form, which is observable as an artistic rendering. The reader, who is at the same time a viewer, is invited to perceptually and imaginatively attend to the artifact as a manifestation of the experient's understanding of the functional nature of God, and in this apprehension of the divine scenario in the textual picture the interpretative motif of God-in-the-painting is revealed.

The process of condensation of an amorphous solid into a rigid matrix can often trap molecules in reversible binding sites. Exchange of the same molecular species with such sites is known to be sensitive to small chemical differences and to distinguish between enantiomers. In addition to their usefulness in chromatographic processes, such materials can separate, by solid phase extraction, specific compounds from complex mixtures. Furthermore, the trapped molecules can have their reactions guided and catalytically changed. The combination of this spontaneously (...) formed system of templates and catalytic sites may support a type of replication cycle, and suggests some pathways from simple chemistry toward the complexities of biology. © 2005 Wiley Periodicals, Inc.

Corporate Social Responsibility (CSR) is a tortured concept. In this paper, we reframe CSR into a number of discrete Corporate Social Responsibilities (CSR’s), each of which can have a positive or negative social impact, and each of which has an endogenous managerially driven component, and an exogenous stakeholder driven component. Using an industry-level sample drawn from the KLD data base, we test the impact of hypothesized drivers of CSR on various CSR’s.

The last‐half of seventeenth‐century England witnessed an increasing number of works published questioning the traditional notions of God's work of creation and providence. Ascribing agency to matter, motion, chance, and fortune, thinkers ranging from Hobbes, Spinoza, modern‐Epicureans, and other presented a challenge to the Anglican defenders of social and ecclesiastical order. By examining the genesis of the Boyle Lectures that began in 1692 with a bequest from Robert Boyle, we can see that while the Lecturers—three of whom will be examined (...) in detail (Richard Bentley, John Harris, and William Whiston)—assiduously defended classical notions of the God–world relationship, they did so without a great sense of panic or pessimism. This transitional period in the mode of conflict or concord between religion and science sheds interesting lights on matters such as argument from design, biogenesis without purposive, personal agents, and scriptural exegesis and scientific inquiries.

Wolf stories, including the systematic and government-sponsored killing of Yukon wolves, provide a context for the examination of assumptions about Western epistemology, and particularly science, in light of the “ethics-based epistemology” presented by Jim Cheney and Anthony Weston, with implications for research, responsibility, and animal welfare. Working from a premise of universal consideration, andminding the ethical basis of knowledge claims, enables richer conceptions of environmental ethics and creates new possibilities for animal welfare and managing for wildlife.

Paul C. H. Lim offers an insightful examination of the polemical debates about the doctrine of the Trinity in seventeenth-century England, showing that this philosophical and theological re-configuration significantly impacted the politics of religion in the early modern period.

The concept of responsibility for health is a significant feature of health discourse and public health policy, but application of the concept is poorly understood. This paper offers an analysis of the concept in two ways. Following an examination of the use of the word ‘responsibility’ in the nursing and wider health literature using three examples, the concept of ‘responsibility for health’ as fulfilling a social function is discussed with reference to policy documents from the UK. The philosophical literature on (...) moral responsibility is introduced, and in considering two versions, reactive attitudes and accountability, it is argued that in application both can be regarded, though with different emphasis, as being constituted in three parts: a responsible agent; having obligations ; and being susceptible to being held responsible if he fails to meet them. The three‐stage model is consistent with the examples of the word responsibility in use, but application to the social function model causes a number of problems for healthcare practice, especially for the reactive attitudes account. Apart from considerable problems in stating what exactly the obligations are and how they can be justified; and how blame might justly be apportioned and by whom, the very ideas of obligation and blame are in conflict within healthcare systems and professional nursing practice which have foundations deeply embedded in the notion of the supremacy of personal autonomy. It is concluded that current application of the concept of responsibility for health is conceptually incoherent, and if it is to retain its place in health policy and discourse, urgent remedy is required.

The underlying modules of existentially closed ▵-algebras are studied. Among other things, it is proved that they are all elementarily equivalent, and that all of them are existentially closed as modules if and only if ▵ is regular. It is also proved that every saturated module in the appropriate elementary equivalence class underlies an e.c. ▵-algebra. Applications to some problems in module theory are given. A number of open questions are mentioned.

Research targeting emotion’s impact on relational episodic memory has largely focused on spatial aspects, but less is known about emotion’s impact on memory for an event’s temporal associations. The present research investigated this topic. Participants viewed a series of interspersed negative and neutral images with instructions to create stories linking successive images. Later, participants performed a surprise memory test, which measured temporal associations between pairs of consecutive pictures where one picture was negative and one was neutral. Analyses focused on how (...) the order of negative and neutral images during encoding influenced retrieval accuracy. Converging results from a discovery study (N = 72) and pre-registered replication study (N = 150) revealed a “forward-favouring” effect of emotion in temporal memory encoding: Participants encoded associations between negative stimuli and subsequent neutral stimuli more strongly than associations between negative stimuli and preceding neutral stimuli. This finding may reflect a novel trade-off regarding emotion’s effects on memory and is relevant for understanding affective disorders, as key clinical symptoms can be conceptualised as maladaptive memory retrieval of temporal details.

Although psychoanalysis and Zen Buddhism derive from theoretical and philosophical assumptions worlds apart, both experientially-based traditions share at their heart a desire for the understanding, development, and growth of the human experience. Paul Cooper utilizes detailed clinical vignettes to contextualize the implications of Zen Buddhism in the therapeutic setting to demonstrate how its practices and beliefs inform, relate to, and enhance transformative psychoanalytic practice. The basic concepts of Zen, such as the identity of the relative and the absolute and (...) the foundational principles of emptiness and dependent-arising, are given special attention as they relate to the psychoanalytic concepts of the unconscious and its processes, transference and countertransference, formulations of self, and more. In addition, through an analysis of apophasis, a unique style of discourse that serves as a basic structure for mystical languages, he provides insight into the structure of the seemingly irrational Zen koan in order to demonstrate its function as a pedagogical and psychological tool. Though mindful of their differences, Cooper’s intent throughout is to illustrate how the practices of both Zen and psychoanalysis become internalized by the individual who engages in them and can, in turn, inform one another in mutually beneficial ways in an effort to comprehend the ramifications of an individual or collective expanding vision.

One of the central problems arising from just the descriptive aspect of Kuhn's theory of scientific development by revolutions concerns the problem of generality. Is Kuhn's theory general enough to encompass the development of all the sciences, including both the natural sciences and the social sciences? The answer to this question is no. It is argued that this negative answer is due not to the nature of the sciences themselves but to the nature of Kuhn's theory and, in particular, its (...) local and reductionistic perspective. First steps toward the construction of a more global and more pluralistic descriptive theory of scientific development are taken. The development of significant episodes in the history of sciences other than physics and chemistry are considered. The immediate goals are to correct the narrow base from which Kuhn starts, to show how some of his basic ideas might be preserved, and to indicate how a theory of types would proceed. (shrink)

This essay uses the concept of reconstruction to make an argument and an intervention in relation to the practice and study of black aesthetics. The argument will have to do with the parochialism of John Dewey, the institutional inertia of professional philosophy, the aesthetic dimensions of the US politics of reconstruction, the centrality of reconstructionist politics to the black aesthetic tradition, and the staging of a reconstructionist argument in the film, Black Panther (Coogler 2018). The intervention aims to address the (...) fact that arguments like these tend not to register properly because of certain reflexive and customary limits on some common forms of philosophical inquiry. The sort of professional philosophy I was raised to practise and value tends not to be particularly inclusive and open-minded, especially when it comes to subjects that bear directly on the thoughts, lives, and practices of people racialized as black. black aesthetics, by contrast, is an inherently ecumenical enterprise, reaching across disciplinary and demographic boundaries to build communities of practice and exchange. Hence the need for an intervention: to create the space for arguments and the people who work with them to function across disciplinary and demographic contexts. (shrink)

We study the relations between abelian groups B and C that every universal (resp. universal-existential) sentence true in B is also true in C, and give algebraic criteria for these relations to hold. As a consequence we characterize the inductive complete theories of abelian groups and prove that they are exactly the model-complete theories.

A mathematical approach to heuristics is proposed, in contrast to Gigerenzer et al.'s assertion that laws of logic and probability are of little importance. Examples are given of effective heuristics in abstract settings. Other short-comings of the text are discussed, including omissions in psychophysics and cognitive science. However, the authors' ecological view is endorsed.

On Obama examines some of the key philosophical questions that accompany the historic emergence of the 44th US president. The purpose of the book is to take seriously the once-common thought that Mr. Obama had ushered in a post-historical age. Three questions organize the argument of the book. Has the US become post-racial? Does Obama’s pragmatism show the way to a post-partisan approach to politics? And does the reining in of US power and ambitions signal the emergence of a post-imperial (...) moment? The book does not answer these questions directly, but considers how Mr. Obama’s public image and career raise the questions, and experiments with some lines of thought that emerge in their light.
