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)

Allthough small business accounts for over 90% of businesses in U.K. and indeed elsewhere, they remain the largely uncharted area of ethics. There has not been any research based on the perspective of small business owners, to define what echical delemmas they face and how, if at all, they resolve them. This paper explores ethics from the perspective of small business owner, using focus groups and reports on four clearly identifiable themes of ethical delemmas; entrepreneurial activity itself, conflicts of personal (...) values with business needs, social responsibility and the impact of owners' personality on business ethics. The mechanisms for resolving ethical dilemmas is not at all clear, as there appears to be a web of filters which are used in an inter-connected way. However a common starting point for resolving an ethical delemma which involves others is based on identifying who it is (e.g., a friend or institution) and the quality of the relationship with that person. The research yielded a rich source of material on business ethics and it is clear that future researchers must focus on this sector if business ethics is to make significant advances. (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.

Mealey's excellent target article rests on several assumptions that may be questioned, including the overarching assumption that sociopathy reflects the failure of a small minority of males to cooperate with the larger group. I suggest that violent competition in ancestral bands cheatinggame was the primary evolutionary precursor of sociopathy. Today's violent sociopath is far more a than a failed cooperator.

In lieu of an abstract, here is a brief excerpt of the content:Editors’ IntroductionElizabeth S. Radcliffe and Mark G. SpencerThis issue opens with the winning essay in the Third Annual Hume Studies Essay Prize competition: “Hume beyond Theism and Atheism” by Dr. Ariel Peckel. Dr. Peckel’s essay was chosen as the winner from among papers submitted by emerging scholars from August 2022 through July 2023. Please see the full prize announcement with information about this talented Hume scholar elsewhere in this (...) issue.

The contest is open to authors ten or fewer years from the Ph.D. and closes on August 1, 2024. If you are eligible, please consult our “Call” for further details!In other Hume Studies news, we have once again acquired a new printer. Christensen Printing (Lincoln, Nebraska), whose work for us was excellent, suddenly closed its business when its owner retired this past year and had no one to succeed him. We received the news just when our November issue was ready to go to press. With the assistance of our friends at the Philosophy Documentation Center, we obtained estimates from three printers and have now engaged Bailey Printing in Charlottesville, Virginia. Our November issue was published on-line by November 1 (at the Philosophy Documentation Center website, the Project Muse website, and the Hume Society website), but the print issue took longer to get to subscribers.For a second time, we want to bring to the attention of our readers that Hume Studies will be marking its 50th year of publication in 2025. As we have previously noted, we are planning an anniversary issue for 50:1 (April 2025). We hope to include among the special features of that issue paragraphs or statements from our readers in answer to this query: “Of all of the articles that have been published in [End Page 7] Hume Studies over the past 50 years, which one is most noteworthy to you?

Pronouns often convey information about a person’s social identity (e.g., gender). Consequently, pronouns have become a focal point in academic and public debates about whether pronouns should be changed to be more inclusive, such as for people whose identities do not fit current pronoun conventions (e.g., gender non-binary individuals). Here, we make an empirical contribution to these debates by investigating which social identities lay speakers think that pronouns should encode and why. Across four studies, participants were asked to evaluate different (...) types of real and hypothetical pronouns, including binary gender pronouns, race pronouns, and identity-neutral pronouns. We sampled participants from two languages with different pronoun systems: English (N = 1,120) and Turkish (N = 260). English pronouns commonly denote binary gender (e.g., he for men), whereas Turkish pronouns are identity-neutral (e.g., o for anyone). Participants’ reasoning about pronouns reflected both a familiarity preference (i.e., participants preferred the pronoun type used in their language) and—critically—participants’ social ideologies. In both language contexts, participants’ ideological beliefs that social groups are inherently distinct (essentialism) and should be hierarchal (social dominance orientation) predicted relatively greater endorsement of binary gender pronouns and race pronouns. A preregistered experimental study with an English-speaking sample showed that the relationship between ideology and pronoun endorsement is causal: Ideologies shape attitudes toward pronouns. Together, the present research contributes to linguistic and psychological theories concerning how people reason about language and informs policy-relevant questions about whether and how to implement language changes for social purposes.

This article examines the responses of two communities to hate crimes in their cities. In particular it explores how community understandings of responsibility shape collective responses to hate crimes. I use the case of Bridesberg, Pennsylvania to explore how anti-racist work is restricted by backward-looking conceptions of moral responsibility (e.g. being responsible). Using recent writings in feminist ethics.(1) I argue for a forward-looking notion that advocates an active view: taking responsibility for attitudes and behaviors that foster climates in which hate (...) crimes are more likely to occur, even when a person's individual actions do not contribute directly to harms. Using the case of Billings, Montana, I explain how recent Not In Our Town campaigns take responsibility for hate crimes in the ways feminist literature suggests. -/- I take as my point of departure hate crimes committed against the family of Bridget Ward, an African American woman, who moved into the suburb of Bridesburg in 1996. When issues of responsibility for racism arose in the local press, most Bridesbergers insisted that their community was not racist; they blamed only the individual vandals. This narrow blame-assigning focus is in keeping with most Anglo-American definitions of responsibility as belonging essentially to individuals and not to communities. Traditionally, moral and legal theory construct responsibility from a perspective that looks downward and back. These perspectives are preoccupied with punishment and reward, praise and blame; they assume justice is done when guilty parties are found and tried. -/- This focus masks deeper community problems. As Elizabeth Spelman remarks, "tolerance is easy if those who are asked to express it need not change a whit." (2) Focus on praise and blame is, in part, a function of race privilege. Bridesberg is 98% white, and part of "the arrogance whitely behavior" is positioning one's self as a judge, expert, and problem solver. (3) The view from this particular subject position limits attention to individuals and their actions, rather than to communities and their practices; it shifts attention away from the fact that Bridesberger's collective practice of distrusting outsiders has lead to hate crimes in the past. Pointing to vandals and claiming "they are racist" does not free one's community of racism. It reinscribes a community spirit that is resistant to change. -/- The second part of this essay explores what communities like Bridesberg might have done to prevent violence. Often there is little individuals alone can do to stop racial violence, but that there is a sense in which community members are obligated to organize themselves. Strategies that focus community responsibility on retribution rather than long-term change, are short lived and ineffective. Anti-racist activism requires a forward-looking view of responsibility: one that aims at inoculating the community against increased risk of violence. This requires taking responsibility for the fact that one's town might foster climates in which hate crimes are more likely to occur. It requires that we begin inquiry in the lives of those harmed. -/- Collective citizen efforts to prevent Aryan groups from gaining a foothold in Billings, Montana offers a clear illustration of how to take responsibility for hate crimes using strategies designed consciously to prevent further hate crimes (e.g., when Black Churches were threatens, all community members attended services there; when a rock was thrown through a window with a menorah, many homes displayed menorahs). The community responses in Billings are a stark contrast to those of Bridesburg, and serve as a powerful example of how forward-looking notions of responsibility can translate into effective political strategy. Although, these strategies are not in and of themselves feminist, they are powerful illustrations of what feminists mean by forward-looking views. The success of resident's collective action and coalition building gave rise to a national Not In Our Town campaign used in about a dozen cities today. (shrink)

Intuitionistic logic is presented here as part of familiar classical logic which allows mechanical extraction of programs from proofs. to make the material more accessible, basic techniques are presented first for propositional logic; Part II contains extensions to predicate logic. This material provides an introduction and a safe background for reading research literature in logic and computer science as well as advanced monographs. Readers are assumed to be familiar with basic notions of first order logic. One device for making this (...) book short was inventing new proofs of several theorems. The presentation is based on natural deduction. The topics include programming interpretation of intuitionistic logic by simply typed lambda-calculus (Curry-Howard isomorphism), negative translation of classical into intuitionistic logic, normalization of natural deductions, applications to category theory, Kripke models, algebraic and topological semantics, proof-search methods, interpolation theorem. The text developed from materal for several courses taught at Stanford University in 1992-1999. (shrink)

Ancient allures the postmodern social subject trapped in the strangeness of time—the time after the end of history. For that time-beaten subject ancient is the unconscious of coherence, predictability, and certainty. Or perhaps that ancient is a glory fled. Whatsoever, ancient is generally sacralized—irrespective of the type of socialization that happened in the past—and journey to the ancient is often deemed to be a pilgrimage. When ideas of the ancient in their individuality and totality inter alia become the natural intellectual (...) resource for rebuilding postmodern societies, discriminative ingenuity becomes an essential faculty. Any uncritical reverence of the ancient becomes antithetical to modern social and political values, inviting the risk of reproducing inequities of the past. This article problematizes such uncritical dependence on the ancient using Ancient Indian Jurisprudence, which has been looked up on as a repository of moral and legal values, as a case in point. It meditates from the experiences and perspectives of an imaginary ‘teaching subject’ on the many pitfalls and possibilities of the ancient as it builds a framework of teaching and learning, and a representative scheme of evaluation for Ancient Indian Jurisprudence.

In the book, basic principles of syncretic logic (sycretics) are expounded upon, with the help of which group relationships of a philosophical nature are treated. Classical philosophical laws are analyzed, new assertions are formulated, laying claim to the position of laws. Syncretic logic is used for constructing the axiomatic theory of carriers and the analysis of its consequences. The problem of the origins of life is considered, the connection between the course of existence and the laws of conservation in physics (...) is expounded upon, the universal scheme of logical operations is described, the components of the structure of a world view are specified. The work is intended for a wide circle of individuals with philosophical and general scientific interests. (shrink)

This fundamental and straightforward text addresses a weakness observed among present-day students, namely a lack of familiarity with formal proof. Beginning with the idea of mathematical proof and the need for it, associated technical and logical skills are developed with care and then brought to bear on the core material of analysis in such a lucid presentation that the development reads naturally and in a straightforward progression. Retaining the core text, the second edition has additional worked examples which users have (...) indicated a need for, in addition to more emphasis on how analysis can be used to tell the accuracy of the approximations to the quantities of interest which arise in analytical limits.

Over the past two years, debate about the use of data taken from Nazi concentration camp experiments has intensified. Many survivors of the Holocaust have been particularly offended at the publication of hypothermia or other data. This article argues against the use of unethically obtained data, and considers the debate from the perspective of the rights of Holocaust victims.

The sequencing of the human genome and decreasing costs of sequencing technology have led to the notion of ‘personalized medicine’. This has been taken by some authors to indicate that personalized medicine will provide individualized treatments solely based on one’s DNA sequence. We argue this is overly optimistic and misconstrues the notion of personalization. Such interpretations fail to account for economic, policy and structural constraints on the delivery of healthcare. Furthermore, notions of individualization based on genomic data potentially take us (...) down the road of genetic reductionism obscuring the role of environmental factors in disease and ill health. We propose that one should see personalized medicine as a way of using personal genomic information to stratify individuals into subpopulations and suggest that personalized medicine be seen within a broader idea of personalized healthcare, reflecting healthcare that integrates personal genomic data into cultural, environmental and personal contexts.

The problem of psychological pain caused by discussions of do not resuscitate status with patients is addressed. Case histories of patients with such distress are given. We propose that not all patients should be informed of their do not resuscitate status, that the information about such status be given incrementally, and that the giving of further information be guided by the patient's reaction to earlier information. While some affirm the duty of the physician always to inform the patient about his (...) or her do not resuscitate status, we affirm the duty of the physician to determine whether the patient wishes to enter into this discussion.

In lieu of an abstract, here is a brief excerpt of the content:102 HISTORY OF PHILOSOPHY historical circumstances a suprahistorical, eternal significance, and that a historian or interpreter of a philosophy will do it justice only if he grasps this lasting truth and content, in addition to comparing it with the opinions of other earlier or later thinkers. One cannot see how a thinker who considered Plato as valid while treating him and others historically could have arrived at a different (...) conclusion. But it is a position admirably expressed that would deserve greater attention and a wider following among the present practitioners of the history of philosophy. Hoffmann's method and style in this, as in most of his other writings, deserve the highest praise, for he combines simplicity with density. His manner of expression reflects his commitment to truth (a commitment curiously omitted by many contemporary existentialists), and the integrity of his character: Hoffmann was one of the few German scholars who made no concessions to Nazism because he was a faithful representative of that German tradition which was incompatible with Nazism: classical humanism in its scholarly, literary and educational meaning, philosophical idealism, and liberal protestantism. Guided by Plato, Kant and Goethe, Hoffmann was untouched by the Romantic and nationalistic strands of German thought. His work transmits to us the precious heritage of a life completely devoted to philosophy and to scholarship, and of an important period in the history of German thought. He omits many things which we have learned in the last few years, or which we may still learn through future studies. Yet he can teach us many important things that are too easily forgotten in our present discussions: the role of Platonism in the history of philosophy and of the sciences, and the fundamental impact of ancient philosophy upon early Christian, medieval and modern thought. It is a heritage which we should try to enlarge, if we can, but also strive to preserve, and to keep alive. PAUL OSKARKRISTELLER Columbia University Studies in Epicurus and Aristotle. By Philip Merlan. (Wiesbaden: Harrassowitz [Klassisch-Philologische Studien, Heft 22], 1960. Pp. viii + 112. P1. 4. DM 12.--) Ever since the publication in 1936 of Bignone's L'Aristotele perduto e la formazione filosofica di Epicuro there have been attempts to define the exact nature of the debt which Epicurus owes to the Peripatos. In this collection of essays, the author of From Platonism to Neoplatonism turns his keen powers of analysis upon a number of specific problems deriving from Plato's Laws and carrying us via Aristotle's Metaphysics and Ethics to Epicurus's theology and beyond. In the first chapter, "Hedone in Epicurus and Aristotle," the author takes us on a generous stroll through hedonist materials, BOOK REVIEWS 103 including an ode by Schiller, to explore the precise meaning of the term hedone. More especially he is concerned to show how close the Epicurean understanding of the term is to that of Aristotle in at least some of his writings, notably Protrepticus and Nic. Eth. H and Met. A. The results of this investigation may be stated in the author's own words: Whether it occurs in Epicurus or in Aristotle, the term hedone can mean anything between gross sensual "pleasure" and entirely spiritual "joy." And on the whole it seems preferable to speak of the philosophy of Epicurus as a philosophy of joy rather than of pleasure. As far as Aristotle is concerned, it seems more appropriate to say that his Changeless Changer (or Changeless Changers) live a life that is filled with joy rather than pleasure, and that his hedonism is ultimately rooted in that of Eudoxus. Chapter 2, "How Many Kinds of Divinities Did Epicurus Recognize?," argues from the theory of the existence of indiscernible non-identicals (Cicero,4cademica 2.17.55; Philodemus De Pietate col. 80 = fr. 40 Us.) and from the theory of "isonomia," i.e., the balancing of one class of things by an equally large class of a different or opposite character (cf. C. Bailey, Greek Atomists, p. 461 ff.) that the Epicureans recognized two types of worshippables, as is indeed suggested by schol. Diog. Laert. 10.139: (I) the popular traditional divinities who are kar arithmon, i.e., severally unique, and... (shrink)

Abstract Philosophical discussion of Alan Turing’s writings on intelligence has mostly revolved around a single point made in a paper published in the journal Mind in 1950. This is unfortunate, for Turing’s reflections on machine (artificial) intelligence, human intelligence, and the relation between them were more extensive and sophisticated. They are seen to be extremely well-considered and sound in retrospect. Recently, IBM developed a question-answering computer (Watson) that could compete against humans on the game show Jeopardy! There are hopes it (...) can be adapted to other contexts besides that game show, in the role of a collaborator of, rather than a competitor to, humans. Another, different, research project --- an artificial intelligence program put into operation in 2010 --- is the machine learning program NELL (Never Ending Language Learning), which continuously ‘learns’ by ‘reading’ massive amounts of material on millions of web pages. Both of these recent endeavors in artificial intelligence rely to some extent on the integration of human guidance and feedback at various points in the machine’s learning process. In this paper, I examine Turing’s remarks on the development of intelligence used in various kinds of search, in light of the experience gained to date on these projects. (shrink)

I address questions about values in model-making in engineering, specifically: Might the role of values be attributable solely to interests involved in specifying and using the model? Selected examples illustrate the surprisingly wide variety of things one must take into account in the model-making itself. The notions of system, and physically similar systems are important and powerful in determining what is relevant to an engineering model. Another example illustrates how an idea to completely re-characterize, or reframe, an engineering problem arose (...) during model-making. I employ a qualitative analogue of the notion of physically similar systems. Historical cases can thus be drawn upon; I illustrate with a comparison between a geoengineering proposal to inject, or spray, sulfate aerosols, and two different historical cases involving the spraying of DDT. The current geoengineering proposal is seen to be like the disastrous and counterproductive case, and unlike the successful case, of the spraying of DDT. I conclude by explaining my view that model-making in science is analogous to moral perception in action, drawing on a view in moral theory that has come to be called moral particularism. (shrink)

Twenty years ago in "Turing's Two Tests for Intelligence" I distinguished two distinct tests to be found in Alan Turing's 1950 paper "Computing Machinery and Intelligence": one by then very well-known, the other neglected. I also explained the significance of the neglected test. This paper revisits some of the points in that paper and explains why they are even more relevant today. It also discusses the value of tests for machine intelligence based on games humans play, giving an analysis of (...) some twentieth century TV game shows and how they relate to the tests for machine intelligence in Turing's paper and in some other tests for machine intelligence that have been proposed since. Their value in distinguishing between 'wise' and simply ‘clever’ AI is discussed. (shrink)
