© 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)

According to the principle of alternative possibilities (PAP), a person is morally responsible for what he has done only if he could have done otherwise. Widerker (Philosophical Perspectives 14: 181-201, 2000) offers an intriguing argument for PAP as it applies to moral blameworthiness. His argument is known as the “What-should-he-have-done defense” of PAP or the “W-defense” for short. In a recent article, Capes (Philosophical Studies 150: 61-77, 2010) attacks Widerker’s argument by rejecting the central premise on which it rests, namely, (...) the premise that a person is blameworthy for his action only if in the circumstances it would be morally reasonable to expect him not to have acted as he did. In this paper, I show that Capes’ criticism does not undermine this premise and, to this extent, Widerker’s argument is safe from Capes’ attack. (shrink)

As the expansion of the Internet and the digital formatting of all kinds of creative works move us further into the information age, intellectual property issues have become paramount. Computer programs costing thousands of research dollars are now copied in an instant. People who would recoil at the thought of stealing cars, computers, or VCRs regularly steal software or copy their favorite music from a friend's CD. Since the Web has no national boundaries, these issues are international concerns. The contributors-philosophers, (...) legal theorists, and business scholars, among others-address questions such as: Can abstract ideas be owned? How does the violation of intellectual property rights compare to the violation of physical property rights? Can computer software and other digital information be protected? And how should legal systems accommodate the ownership of intellectual property in an information age? Intellectual Property is a lively examination of these and other issues, and an invaluable resource for librarians, lawyers, businesspeople, and scholars. (shrink)

We address how listeners perceive temporal regularity in music performances, which are rich in temporal irregularities. A computational model is described in which a small system of internal self‐sustained oscillations, operating at different periods with specific phase and period relations, entrains to the rhythms of music performances. Based on temporal expectancies embodied by the oscillations, the model predicts the categorization of temporally changing event intervals into discrete metrical categories, as well as the perceptual salience of deviations from these categories. The (...) model's predictions are tested in two experiments using piano performances of the same music with different phrase structure interpretations (Experiment 1) or different melodic interpretations (Experiment 2). The model successfully tracked temporal regularity amidst the temporal fluctuations found in the performances. The model's sensitivity to performed deviations from its temporal expectations compared favorably with the performers' structural (phrasal and melodic) intentions. Furthermore, the model tracked normal performances (with increased temporal variability) better than performances in which temporal fluctuations associated with individual voices were removed (with decreased variability). The small, systematic temporal irregularities characteristic of human performances (chord asynchronies) improved tracking, but randomly generated temporal irregularities did not. These findings suggest that perception of temporal regularity in complex musical sequences is based on temporal expectancies that adapt in response to temporally fluctuating input. (shrink)

Spirit of the Environment brings spiritual and religious concerns to environmental issues. Providing a much needed alternative to exploring human beings' relationship to the natural world through the restrictive lenses of 'science', 'ecology', or even 'morality', this book offers a fresh perspective to the field. Spirit of the Enironment addresses: * the environmental attitudes of the major religions; * the relationship between art and nature; * the Gaia hypothesis; * the non-instrumental values which have inspired environmental concern. Contributors range from (...) a variety of disciplines including philosophy, comparative religion, education and social anthropology, providing students with an intriguing survey on the role that spirituality and religion play in nature. This is a vital collection for those eager to examine the relationship between the spiritual and the environment. (shrink)

We address the problem of musical variation (identification of different musical sequences as variations) and its implications for mental representations of music. According to reductionist theories, listeners judge the structural importance of musical events while forming mental representations. These judgments may result from the production of reduced memory representations that retain only the musical gist. In a study of improvised music performance, pianists produced variations on melodies. Analyses of the musical events retained across variations provided support for the reductionist account (...) of structural importance. A neural network trained to produce reduced memory representations for the same melodies represented structurally important events more efficiently than others. Agreement among the musicians' improvisations, the network model, and music‐theoretic predictions suggest that perceived constancy across musical variation is a natural result of a reductionist mechanism for producing memory representations.

[Open access] In this book symposium the author takes up questions from phenomenology, hermeneutics, ethical theory, and intellectual history raised by a group of scholarly interlocutors from a range of backgrounds. In the course of engaging with these issues, he discusses, inter alia, McDowell’s realism, Jonathon Lear’s work on the end of a world, Michael Oakeshott’s view of selfhood, Heidegger’s conception of Jemeinigkeit, Uexküll’s notion of Umwelt, and Gadamer’s hermeneutic conception of truth.

David Miller elegantly and provocatively reformulates critical rationalism—the revolutionary approach to epistemology advocated by Karl Popper—by answering its most important critics. He argues for an approach to rationality freed from the debilitating authoritarian dependence on reasons and justification. "Miller presents a particularly useful and stimulating account of critical rationalism. His work is both interesting and controversial... of interest to anyone with concerns in epistemology or the philosophy of science." —Canadian Philosophical Reviews.

David Miller is the foremost exponent of the purist critical rationalist doctrine and here presents his mature views, discussing the role that logic and argument play in the growth of knowledge, criticizing the common understanding of argument as an instrument of justification, persuasion or discovery and instead advocating the critical rationalist view that only criticism matters. Miller patiently and thoroughly undoes the damage done by those writers who attack critical rationalism by invoking the sterile mythology of induction and justification (...) that it seeks to sweep away. In addition his new material on the debate on verisimilitude is essential reading for all working in this field. (shrink)

This paper articulates and defends a noncognitive, care-based view of identification, of what privileged psychic subset provides the source of self-determination in actions and attitudes. The author provides an extended analysis of "caring," and then applies it to debates between Frankfurtians, on the one hand, and Watsonians, on the other, about the nature of identification, then defends the view against objections.

"In the first study of its kind, David W. Johnson's "Watsuji on Nature" reconstructs the astonishing philosophy of nature of Watsuji Tetsurō (1889-1960), situating it in relation both to his reception of the thought of Heidegger and to his renewal of core ontological positions in classical Confucian and Buddhist philosophy. Johnson shows that for Watsuji we have our being in the lived experience of nature, one in which nature and culture compose a tightly interwoven texture called "fūdo". By fully (...) unfolding Watsuji's novel and radical claim that this is a setting that is neither fully external to human subjectivity nor merely a product of it, this book also sets out what still remains unthought in this concept, as well as in the relational structure that underwrites it. Johnson argues that what remains unarticulated is nothing less than the recovery of a reenchanted conception of nature and an elucidation of the wide-ranging implications of a relational conception of the self for questions about the disclosive character of experience, the distinction between fact and value, and the possibility of a place-based ecological ethics. In an engagingly lucid and deft analysis, "Watsuji on Nature" radically expands our appreciation of twentieth-century Japanese philosophy and shows what it has to offer to a global philosophical conversation"--Provided by publisher.

Many philosophers have taken there to be an important relation between personal identity and several of our practical concerns (among them moral responsibility, compensation, and self-concern). I articulate four natural methodological assumptions made by those wanting to construct a theory of the relation between identity and practical concerns, and I point out powerful objections to each assumption, objections constituting serious methodological obstacles to the overall project. I then attempt to offer replies to each general objection in a way that leaves (...) the project intact, albeit significantly changed. Perhaps the most important change stems from the recognition that the practical concerns motivating investigation into personal identity turn out to be not univocal, as is typically thought, such that each of the different practical concerns may actually be related to personal identity in very different ways.

In this paper, I attempt to show that the moral/conventional distinction simply cannot bear the sort of weight many theorists have placed on it for determining the moral and criminal responsibility of psychopaths. After revealing the fractured nature of the distinction, I go on to suggest how one aspect of it may remain relevant—in a way that has previously been unappreciated—to discussions of the responsibility of psychopaths. In particular, after offering an alternative explanation of the available data on psychopaths and (...) their judgments of various sorts of norm transgressions, I put forward a hybrid theory of their responsibility, suggesting how they might be criminally responsible, while nevertheless failing to meet the conditions for an important arena of moral responsibility.

In our age of globalization, we need a theory of global management consistent with our common human nature. The place to begin in developing such a theory is the philosophy of traditional cultures. The article focuses on African philosophy and its fruitfulness for contributing to a theory of management consistent with African traditional cultures. It also looks briefly at the Confucian and Platonic-Aristotelian traditions and notes points of agreement with African traditions. It concludes that the needed theory of global management (...) should regard the firm as a community, not a collection of individuals, and should understand the purpose of management as promoting the common good.

Attacks nothing less than the currently prevailing worldphilosophy--humanism, which the author feels is exceedingly dangerous in itshidden assumptions.

David Hume's writings on history, politics and philosophy have shaped thought to this day. His bold scepticism ranged from common notions of the 'self' to criticism of standard theistic proofs. He insisted on grounding understandings of popular religious beliefs in human psychology rather than divine revelation, and he aimed to disentangle philosophy from religion in order to allow the former to pursue its own ends. In this book, Professors David W Purdie and Peter S Fosl decipher some of (...) Hume's most challenging texts for the modern reader, while preserving the sharp intellect and undaunted nerve for which Hume is famous. Hume's spirit is brought alive for contemporary times and his writing is made accessible for its intended audience: the general public."-- Back cover. (shrink)

This paper argues that explicit reading instruction should be part of lower level undergraduate philosophy courses. Specifically, the paper makes the claim that it is necessary to provide the student with both the relevant background knowledge about a philosophical work and certain metacognitive skills (e.g. their ability to reflect on the learning process) that enrich the reading process and their ability to organize the content of a philosophical text with other aspects of knowledge. A “How to Read Philosophy” handout and (...) student reactions to the handout are provided. (shrink)

Originally published in 1957, the primary aim of this study was to shed light upon the logical character of the psychology of perception. D.W. Hamlyn begins by delimiting the field of psychological inquiry into perception, then gives a detailed account of the types of explanation appropriate in the field. He maintains that these explanations have certain important peculiarities which distinguish them from other scientific inquiries. In view of the central importance of Gestalt Theory in this field an account is given (...) of its origins, and its main features are critically discussed. The work should still be of considerable interest to both philosophers and psychologists, as well as to all those interested in the relations between the two subjects. (shrink)

The interest in and enthusiasm for urban agriculture (UA) in urban communities, the non-profit sector, and governmental institutions has grown exponentially over the past decade. Part of the appeal of UA is its potential to improve the civic health of a community, advancing what some call food democracy. Yet despite the increasing presence of the language of civic agriculture or food democracy, UA organizations and practitioners often still focus on practical, shorter-term projects in an effort both to increase local involvement (...) and to attract funding from groups focused on quantifiable deliverables. As such, it seems difficult to move beyond the rhetoric of food democracy towards significant forms of popular participation and deliberation within particular communities. In this paper we provide a theoretical framework—deep democracy—that helps to contextualize nascent attempts at civic agriculture or food democracy within a broader struggle for democratic practices and relationships. We argue that urban agriculture efforts are well positioned to help citizens cultivate lasting relationships across lines of difference and amidst significant power differentials—relationships that could form the basis of a community’s collective capacity to shape its future. We analyze the theory of deep democracy through recent experiences with UA in Denver, Colorado, and we identify ways in which UA can extend its reach and impact by focusing more consciously on its political or civic potential.

If we want to see justice done with regard to responsibility, then we must either (i) allow that people are never morally responsible, (iia) show that luck is not ubiquitous or at least that (iib) ubiquitous luck is not moral, or (iii) show that ascriptions of responsibility can retain justice despite the omnipresence of luck. This paper defends (iii); ascriptions of responsibility can be just even though luck is ubiquitous.

Derek Parfit claims that, at certain times and places, the metaphysical units he labels *'selves" may be thought of as the morally significant units (I.e., the objects of moral concern) for such things as resource distribution, moral responsibility, commitments, etc. But his concept of the self is problematic in important respects, and it remains unclear just why and how this entity should count as a moral unit in the first place. In developing a view I call *'Moderate Reductionism," I attempt (...) to resolve these worries, first by offering a clearer, more consistent account of what the concept of *'self ' should involve, and second by arguing for why selves should indeed be viewed as moral (and prudential) units. I then defend this view in detail from both *'conservative" and *'extreme" objections. (shrink)

This book discusses the development of Edward Tolman's purposive behaviourism from the 1920s to the 1950s, highlighting the tension between his references to cognitive processes and the dominant behaviourist trends. It shows how Tolman incorporated concepts from European scholars, including Egon Brunswik and the Gestalt psychologists, to justify a more purposive form of behaviourism and how the theory evolved in response to the criticisms of his contemporaries. The manuscript also discusses Tolman's political activities, culminating in his role in the California (...) loyalty oath controversy in the 1950s. Tolman was involved in a number of progressive causes during his lifetime, activities that drew the attention of both state legislators in California and the Federal Bureau of Investigation. It treats Tolman's theoretical and political activities as emanating from the same source, a desire to understand the learning process in a scientific manner and to apply these concepts to improve the human condition.

In this paper we study abstract elementary classes using infinitary logics and prove a number of results relating them. For example, if is an a.e.c. with Löwenheim–Skolem number κ then is closed under L∞,κ+-elementary equivalence. If κ=ω and has finite character then is closed under L∞,ω-elementary equivalence. Analogous results are established for . Galois types, saturation, and categoricity are also studied. We prove, for example, that if is finitary and λ-categorical for some infinite λ then there is some σLω1,ω such (...) that and contain precisely the same models of cardinality at least λ. (shrink)

This paper attempts to reconcile two ideas that seem fundamentally opposed to one another: the reality of the self and the doctrine of no-self. Buddhism offers a form of spiritual equanimity that turns on the denial of a self. Nonetheless, there seem to be good reasons to hold onto the reality of the self. The existence of a self enables us to account for praise and blame, the hopes for oneself that motivate actions, and attachments to the selves of others (...) in bonds of love and affection. I show how it may be possible to reconcile the reality of the self with a particular interpretation of the no-self doctrine by engaging with the work of thinkers from the phenomenological tradition such as Merleau-Ponty, Zahavi, Gallagher, and Petitmengin.

While a number of classical pragmatists crafted their philosophies in conjunction with a careful study of Hegel's works, others saw their philosophies emerge in antagonism with proponents of Hegel. In this paper, we offer an instance of the latter case. Namely, we show that the impetus for Charles S. Peirce's early articulation and avowal of realism (the claim that some generals are real) was William Torrey Harris's claim that the formal laws of logic lacked universal validity. According to Harris, the (...) leading representative of Hegelism in the United States, the universal validity of the laws of logic rested on a nominalistic metaphysics that a Hegelian-realism showed to be false. In response to this charge, we articulate how Peirce's attempt to prove the universal validity of the laws of logic resulted in avowing a realism that differed from both nominalism and Harris's Hegelian-realism.

Two experiments using a realistic version of the selection task examined the relationship between participants' probability estimates of finding a counter example and their selections. Experiment 1 used everyday categories in the context of a scenario to determine whether or not the number of instances in a category affected the estimated probability of a counter-example. Experiment 2 modified the scenario in order to alter participants' estimates of finding a specific counter-example. Unlike Kirby 1994a, but consistent with his proposals, both studies (...) showed that probability estimates significantly predicted selection. Overall results point to the value of understanding selections in terms of their subjective expected utility. (shrink)

Cooperative learning processes have been rediscovered and are being used throughout the country on every level. The basic elements of cooperative goal structure are positive interdependence, individual accountability, face-to-face interaction, and cooperative skills. The teacher's role in structuring cooperative learning situations involves clearly specifying lesson objectives, placing students in productive learning groups and providing appropriate materials, clearly explaining the cooperative goal structure, monitoring students, and evaluating performance. For cooperative learning groups to be productive, students must be able to engage in (...) the needed collaborative skills. Cooperative skills and academic skills can be taught simultaneously. The implementation of cooperative learning needs to be coupled with the implementation of collaborative professional support groups among educators. Both the success of implementation efforts and the quality of life within most schools depend on teachers and other staff members cooperating with each other. Support for the program takes as careful structuring and monitoring as does cooperative learning. (JD). (shrink)

ABSTRACT:Although business ethicists have theorized frequently about the virtues and vices of employee loyalty, the concept of loyalty remains loosely defined. In this article, we argue that viewing loyalty as a cognitive phenomenon—an attitude that resides in the mind of the individual—helps to clarify definitional inconsistencies, provides a finer-grained analysis of the concept, and sheds additional light on the ethical implications of loyalty in organizations. Specifically, we adopt the psychological contract perspective to analyze loyalty's cognitive dimensions, and treat loyalty as (...) an individual-level construction of perceived reciprocal obligations. Based upon this perspective, we present a three-tiered framework of loyalty that provides a psychologically informed definition of the concept, specifies the variety of obligation types that loyalty can imply, and anticipates the potential for asymmetrical loyalty configurations between employers and employees. We use the framework to articulate moral issues associated with both symmetrical and asymmetrical loyalty configurations and discuss the implications of the framework for theory and practice.

This is a study of J.G. Fichte’s philosophy of mathematics and theory of geometry. It investigates both the external, formal & internal, cognitive parallels between the axioms, intuitions and constructions of geometry and the scientific methodology of the Fichtean system of philosophy. In contrast to 'ordinary' Euclidean geometry, in his Erlanger Logik of 1805 Fichte posits a model of an 'ursprüngliche' or original geometry. – That is to say, a synthetic and constructivistic conception of geometry grounded in ideal archetypal elements (...) that are grasped through geometrical or intelligible intuition. -/- Accordingly, this study classifies Fichte’s philosophy of mathematics as a whole as a species of mathematical Platonism or neo-Platonism, and concludes that the Wissenschaftslehre itself may be read as an attempt at a new philosophical mathesis, or a “mathesis of the mind.” -/- .

Agricultural decision making is characterized by two challenges common to multiple arenas: linking science to decision making and linking science and decision making across multiple levels. The U.S. agricultural research, education, and extension system was designed to address these challenges. By investigating this system, this study deepens the understanding of science and decision making, specifically exploring the notion of boundary organizations in two significant ways. First, it provides a preliminary test of the hypothesis that boundary organizations mediate between the shifting (...) domains of science and policy, finding that they are instrumental in creating and maintaining an integrated system of assessment and decision making for addressing depletion of the High Plains Aquifer. Second, it extends the concept of boundary organization beyond the science-policy dimension to incorporate the dimension of levels of organization—not only bridging science and policy but linking science and policy across different levels.

Within political theory there has been a recent surge of interest in the themes of loss, grief, and mourning. In this paper i address questions about the politics of mourning through a critical engagement of the work of Judith Butler. I argue that Butler's work remains tethered to an account of melancholic subjectivity derived from her early reading of Freud. These investments in melancholia compromise Butler's recent ethico-political interventions by obscuring the ambivalence of political engagements and the possibilities of achieving (...) and sustaining non-dogmatic identities. To overcome this impasse I argue for an alternative framing of mourning by turning to the psychoanalytic theory of Melanie Klein. An account of mourning that leans upon Klein's work cashes in on the ethical and political promises that are immanent yet unrealized in Butler's recent work while providing a new orientation for mourning in, and for, democratic politics.

Some philosophers have argued recently that the content of perception is either entirely or mainly non- conceptual. Much of the motivation for that view derives from theories of information processing, which are a modern version of ancient considerations about the causal processes underlying perception. The paper argues to the contrary that perception is essentially concept- dependent. While perception must have a structure derived from what is purely sensory, and is thereby dependent on processes involving information in the technical sense which (...) Gibson said amounted to structure, the information which perception provides about the world depends on the concepts which we have. (shrink)

Processes governing the creation, perception and production of spoken words are sensitive to the patterns of speech sounds in the language user’s lexicon. Generative linguistic theory suggests that listeners infer constraints on possible sound patterning from the lexicon and apply these constraints to all aspects of word use. In contrast, emergentist accounts suggest that these phonotactic constraints are a product of interactive associative mapping with items in the lexicon. To determine the degree to which phonotactic constraints are lexically mediated, we (...) observed the effects of learning new words that violate English phonotactic constraints on phonotactic perceptual repair processes in nonword consonant-consonant-vowel stimuli. Subjects who learned such words were less likely to “repair” illegal onset clusters and report them as legal ones. Effective connectivity analyses of MRI-constrained reconstructions of simultaneously collected magnetoencephalography and EEG data showed that these behavioral shifts were accompanied by changes in the strength of influences of lexical areas on acoustic-phonetic areas. These results strengthen the interpretation of previous results suggesting that phonotactic constraints on perception are produced by top-down lexical influences on speech processing. (shrink)

Some psychiatrists believe that “demoralization syndrome” is a diagnosable cognitive disorder characterized in its extreme form by morbid existential distress. If they are right, then it should be an important part of our thinking about end of life decisionmaking. A demoralized patient would be unable to think reliably about the remainder of her life, and therefore incompetent to decide to commit physician‐assisted suicide.
