An account of how a rational agent should revise beliefs in the light of new evidence.

Our regimentation of Goodman and Myhill’s proof of Excluded Middle revealed among its premises a form of Choice and an instance of Separation.Here we revisit Zermelo’s requirement that the separating property be definite. The instance that Goodman and Myhill used is not constructively warranted. It is that principle, and not Choice alone, that precipitates Excluded Middle.Separation in various axiomatizations of constructive set theory is examined. We conclude that insufficient critical attention has been paid to how those forms of Separation fail, (...) in light of the Goodman–Myhill result, to capture a genuinely constructive notion of set.

Informally rigorous mathematical reasoning is relevant. So too should be the premises to the conclusions of formal proofs that regiment it. The rule Ex Falso Quodlibet induces spectacular irrelevance. We therefore drop it. The resulting systems of Core Logic C and Classical Core Logic C+ can formalize all the informally rigorous reasoning in constructive and classical mathematics respectively. We effect a revised match-up between deducibility in Classical Core Logic and a new notion of relevant logical consequence. It matches better the (...) deducibility relation of Classical Core Logic than does the Tarskian notion of consequence. It is implosive, not explosive. (shrink)

The one-page 1978 informal proof of Goodman and Myhill is regimented in a weak constructive set theory in free logic. The decidability of identities in general (⁠|$a\!=\!b\vee\neg a\!=\!b$|⁠) is derived; then, of sentences in general (⁠|$\psi\vee\neg\psi$|⁠). Martin-Löf’s and Bell’s receptions of the latter result are discussed. Regimentation reveals the form of Choice used in deriving Excluded Middle. It also reveals an abstraction principle that the proof employs. It will be argued that the Goodman–Myhill result does not provide the constructive set (...) theorist with a dispositive reason for not adopting (full) Choice. (shrink)

Cet article expose, à partir de deux cas, certaines difficultés de l’adoption. Il vise à montrer le décalage entre le désir des adoptants et la réalité parfois très dure qu’ils vont devoir affronter. Surtout lorsqu’il s’agit d’enfants de plus de cinq ans, porteurs d’un passé traumatique qui reste non dit. La création de liens forts se fait cependant au milieu de ce vécu difficile et, dans le meilleur des cas, les parents y jouent alors un rôle de soignants.

As the new Cell-free DNA (Cf-DNA) prenatal screening test for Down syndrome was being introduced into the UK’s fetal anomaly screening program, Down syndrome charities had an opportunity to participate. An experience of co-production where we were the minority voice then followed. This paper explores that process and our experience as a charity. Institutional and societal structures meant that it was difficult to be heard and a significant amount of bias was noted within the program. Consequently, our viewpoints were often (...) considered and then dismissed. However, at times we were listened to, and feel that there were some valuable changes made resulting from our involvement. The end product was far from reflective of all that we stand for, and there are still lessons to be learned in England about the need to place a higher value on minority voices of lived experience in a co-production exercise.

Towards Identity in the Psychoanalytic Encounter addresses the theme of identification and identity in the psychoanalytic clinic as elaborated by Jacques Lacan over the course of his teaching. In psychoanalysis the subject who is summoned "to speak himself", is by definition lacking in identity. His question is "What am I?" but, as he is only represented by his words, his being is "always elsewhere", within other words that are yet to come. Thus a paradox: one seeks via speech the identity (...) of a being who, through his speech, is not identifiable. Yet the fact remains, he has a body, and he is riveted to sufferings that psychoanalysis, from Freud to Lacan, identified, which are not accidental, which we call repetition and symptom, and which shift the question of identity, because a One, real, is at play in them. Towards Identity in the Psychoanalytic Encounter will be key reading for the study and research of Lacanian psychoanalysis and all practitioners interested in Lacan's teaching, as well as other discourses such as philosophy, art, literature and history.

The late Vivienne Westwood sketched a role for fashion that elevates it from the prosaic to the status of art, as something important, life-enhancing, and worthy of pursuit. Here, a philosophical treatment of Westwood’s vision of fashion that does justice to the artistic and life-enhancing value that fashion can realise is offered, using an emergent theory in contemporary analytic aesthetics. The virtue theory of art delineates the intrinsic worth of art in terms of the opportunities it provides for us to (...) exercise and cultivate virtues such as courage, self-expression, imagination, wit, or authenticity. Our engagement with art can subsequently be genuinely life-enhancing in lieu of the constitutive role the virtues play in living well. The present study takes Westwood’s claims as a jumping-off point, considering how they speak not just to her own designs but to our relationship with our clothes more broadly. Fashion is defended as a practice that performs this function in analogous ways to other genres of art and thus has clear artistic value as well as enables us to live well. Given this potential, just as Westwood claimed, there are reasons to perform the practice well because it has importance for the ways in which it can realise artistic value and aid us in living well.

Has Jacques Lacan's impact on psychoanalysis really been assessed? His formulation that the Freudian unconscious is "structured like a language" is well-known, but this was only the beginning. There was then the radically new thesis of the "real unconscious". Why this step? Searching for the Ariadne's thread that runs throughout Lacan's ever-evolving teaching, this book illuminates the questions implicit in each step, and sheds new light on his revisions and renewals of psychoanalytic concepts. In tracing these, the author brings out (...) their consequences for the clinic, and in particular, for the subject, for symptoms, for affects, and for the aims of treatment itself. The last section of the book examines the political import of these developments. If many analysts since Freud have dreamt of reinventing psychoanalysis, the author shows the ways in which Lacan succeeded in this reinvention. (shrink)

Chaque fois que nous chantons dans le choeur ou jouons dans l'orchestre, comme lorsque nous pénétrons dans un monument fédérant l'espace urbain, tout notre être s'éprouve soudain d'une façon inédite et multi-dimensionnée. Nous contemplons alors un espace-temps rendu holistique, tout en détaillant les singularités linéaires de mouvements spiralés rythmiques, mélodiques et harmoniques, dont la synergie provoquera, par rebond, notre accession à une dimension d'ouverture, d'écoute et d'être, d'autant plus supérieure qu'y est intimement présente la dimension communautaire. Ainsi apprenons-nous, par et (...) au sein de l'invariant et du géométrisme qui structurent toute oeuvre d'art, à penser de façon entière et globalisée, à travers un espace mental infiniment élargi – particulièrement à l'altérité, seule apte à rassembler et fonder tout l'ensemble de notre activité à tous les plans, du plus physique au plus conceptuel et de l'idée à sa dimension la plus spirituelle.

Over the past 50 years the diversity of higher education faculty in the mathematical, physical, computer, and engineering sciences has advanced very little at 4-year universities in the United States. This is despite laws and policies such as affirmative action, interventions by universities, and enormous financial investment by federal agencies to diversify science, technology, mathematics, and engineering career pathways into academia. Data comparing the fraction of underrepresented minority postdoctoral scholars to the fraction of faculty at these institutions offer a straightforward (...) empirical explanation for this state of affairs. URM postdoc appointments lag significantly behind progress in terms of both undergraduate and Ph.D.-level STEM student populations. Indeed, URM postdoc appointments lag well-behind faculty diversity itself in the MPCES fields, most of which draw their faculty heavily from the postdoctoral ranks, particularly at research-intensive universities. Thus, a sea-change in how postdocs are recruited, how their careers are developed, and how they are identified as potential faculty is required in order to diversify the nation’s faculty, and particularly the R1 MPCES professoriate. Our research shows that both Ph.D. students and postdocs benefit from intentional structure at various levels of their respective “apprentice” experiences, a factor that we believe has been neglected. Several key structural approaches are highly effective in these regards: A collaborative approach in which leading research universities collectively identify outstanding URM candidates; Faculty engagement in recruiting and supporting these postdocs; Inter-institutional exchange programs to heighten the visibility and broaden the professional experiences of these postdocs; Community-building activities that create a sense of belonging and encourage continuing in academia for each cohort; and Continuing research based on outcomes and new experimental approaches. The California Alliance, consisting of UC Berkeley, UCLA, Caltech, and Stanford, has been engaged in such a program for almost a decade now, with most of the California Alliance URM postdocs now in tenure track positions or on the path toward careers as faculty at research intensive institutions. If this approach was brought to scale by involving the top 25 or so URM Ph.D.-producing R1 institutions in the MPCES fields, about 40% of the national URM postdoctoral population in these fields could be affected. Although this impact would fall short of bringing URM MPCES faculty ranks up to full representation of the United States population as a whole, it would vastly improve the outlook for URM students and their aspirations to take on leadership roles as scientists and engineers.

An ethic of care acknowledges the centrality of the role of caring relationships in moral education. Care ethics requires a conception of ?care? that differs from the quotidian use of the word. In order to teach care ethics more effectively, this article discusses four interrelated ways that teachers? understandings of care differ from care ethics: (1) conflating the term of reference ?care? with its quotidian use; (2) overlooking the challenge of developing caring relationships; (3) tending toward monocultural understandings of care; (...) and (4) separating affect and intellect. Awareness of these conceptions of care supports teacher educators to teach care ethics in more meaningful and relevant ways. We explore stories and their dramatization as a medium to facilitate effective and in-depth teaching of care ethics. (shrink)

Cet ouvrage propose une exploration de l'aventure doctorale dans le regard de celles et ceux qui la vivent, les doctorant·e·s, au travers du prisme des émotions. Il aborde, dans une perspective psychopédagogique, les défis inhérents à cette formation exigeante dont l'une des finalités est la construction individuelle et sociale des connaissances. À partir de deux constats préoccupants - le taux d'abandon élevé et l'état de santé critique des doctorant·e·s - l'ouvrage questionne les conditions individuelles et situationnelles qui soutiennent ou entravent (...) le processus d'apprentissage et d'appropriation créative, en présumant que le bien-être constitue la pierre angulaire de la (trans)formation. Après quelques balises théoriques, des éclairages sur l'expérience doctorale sont amenés en deux volets complémentaires. Le premier dresse un panorama international de sept tendances issues de 70 recherches réalisées au cours des vingt dernières années. Le deuxième présente les résultats de l'étude longitudinale menée par l'autrice entre 2016 et 2017 auprès de 26 doctorant·e·s d'une université suisse. Les leviers et les freins du quotidien sont décrits à partir de 256 évènements signifi catifs. Puis, 26 vignettes d'évènements particulièrement (dé)mobilisateurs illustrent comment ces doctorant-e-s se (trans)forment durant leurs activités au contact de leur environnement. L'ouvrage se termine par une réfl exion critique sur l'accompagnement du doctorat et la culture pédagogique dans laquelle il s'inscrit. Des recommandations sont proposées à l'usage des actrices et acteurs de la formation doctorale, pouvant inspirer plus largement celles et ceux de la formation post-obligatoire"--Page 4 of cover.

Unquenched desire, the dividing up of the drives, repetition, and symptom are the keywords for the effects that the unconscious, as deciphered by Freud, has on the body. Harmony is not on the agenda, but rather the discordance, unlinking, and arrogance of cynical jouissances. It seems that the discourse of capitalism is today increasing their deleterious consequences - with all of these demonstrative suicides, but also suicides as diverse as those of terrorists, Tibetan monks, those beleaguered by the capitalist enterprise, (...) and all the hopeless of our time. Hence the question that Lacan posed concerning the possible "humanisation" of this denatured animal, about whom Freud did not hesitate to say that he is a wolf to man, even though he has always made community. What will the psychoanalyst say about possible solutions, he whose act excludes the call to norms of any kind? Humanisation? is the 2013-2014 volume of the annual seminar held by the author at the Clinical College of the Lacanian Field in Paris. (shrink)

The Taming of the True continues the project Neil Tennant began in Anti-realism and Logic of investigating and defending anti-realism. Tennant’s earlier book anticipated a second volume, in which issues related to empirical discourse would be addressed in greater detail. The Taming of the True provides this sequel. It also attempts a ground-clearing project, by addressing challenges to some of the presuppositions and implications of Tennant’s anti-realist position. Finally, it takes an opportunity to revisit some of the (...) issues examined in the earlier book, in light of the evolving debate over realism and anti-realism. (shrink)

Cochlear implants electrically stimulate surviving auditory neurons in the cochlea to provide severely or profoundly deaf people with access to hearing. Signal processing strategies derive frequency-specific information from the acoustic signal and code amplitude changes in frequency bands onto amplitude changes of current pulses emitted by the tonotopically arranged intracochlear electrodes. This article first describes how parameters of the electrical stimulation influence the loudness evoked and then summarizes two different phenomenological models developed by McKay and colleagues that have been used (...) to explain psychophysical effects of stimulus parameters on loudness, detection, and modulation detection. The Temporal Model is applied to single-electrode stimuli and integrates cochlear neural excitation using a central temporal integration window analogous to that used in models of normal hearing. Perceptual decisions are made using decision criteria applied to the output of the integrator. By fitting the model parameters to a variety of psychophysical data, inferences can be made about how electrical stimulus parameters influence neural excitation in the cochlea. The Detailed Model is applied to multi-electrode stimuli, and includes effects of electrode interaction at a cochlear level and a transform between integrated excitation and specific loudness. The Practical Method of loudness estimation is a simplification of the Detailed Model and can be used to estimate the relative loudness of any multi-electrode pulsatile stimuli without the need to model excitation at the cochlear level. Clinical applications of these models to novel sound processing strategies are described. (shrink)

This book surveys the vast body of medieval Jewish philosophy, devoting ample discussion to major figures such as Saadiah Gaon, Maimonides, Abraham Ibn Ezra, Judah Halevi, Abraham Ibn Daoud, and Gersonides, as well as presenting the ancillary texts of lesser known authors. Sirat quotes little-known texts, providing commentary and situating them within their historical and philosophical contexts. A comprehensive bibliography directs the reader to the texts themselves and to recent studies.

In spite of the numerous efforts made to control their transmission, parasite schistosomes still represent a serious public health concern and a major economic problem in many developing countries. Praziquantel (PZQ) is the drug of choice for the treatment of schistosomiasis and the only one that is available for mass chemotherapy. However, its widespread use and its inefficacy on juvenile parasites raise fears that schistosomes will develop drug resistance, and make the development of alternative drugs highly desirable. Protein tyrosine kinases (...) (PTKs) are key molecules that control cell differentiation and proliferation and they already represent important targets for molecular cancer therapy. The recent characterization in Schistosoma mansoni of several cytosolic and receptor PTKs, with properties similar but also divergent from their vertebrate counterparts, opens new perspectives for the development of novel strategies in chemotherapy of schistosomiasis, which could be based on the use of parasite‐specific tyrosine phosphorylation inhibitors.

Affect is a high-stakes topic in psychoanalysis, but there has long been a misperception that Lacan neglected affect in his writings. We encounter affect at the beginning of any analysis in the form of subjective suffering that the patient hopes to alleviate. How can psychoanalysis alleviate such suffering when analytic practice itself gives rise to a wide range of affects in the patient’s relationship to the analyst? Lacanian Affects: The Function of Affect in Lacan’s Work, is the first book to (...) explore Lacan’s theory of affect and its implications for contemporary psychoanalytic practice. In it, Colette Soler discusses affects as diverse as the pain of existence, hatred, ignorance, mourning, sadness, "joyful knowledge," boredom, moroseness, anger, shame, and enthusiasm. Soler’s discussion culminates in a highlighting of so-called enigmatic affects: anguish, love, and the satisfaction related to the end of an analysis. Lacanian Affects provides a unique and compelling account of affect that will prove to be an essential text for psychoanalysts, psychiatrists, psychotherapists, psychologists, and social workers.

I examine the consistency between contemporary environmentalist ideals and Buddhist philosophy, focusing, first, on the problem of value in nature. I argue that the teachings found in the Pāli canon cannot easily be reconciled with a belief in the intrinsic value of life, whether human or otherwise. This is because all existence is regarded as inherently unsatisfactory, and all beings are seen as impermanent and insubstantial, while the ultimate spiritual goal is often viewed, in early Buddhism, as involving a deep (...) renunciation of the world. Therefore, the discussion focuses mostly on the Mahāyāna vehicle, which, I suggest has better resources for environmentalism because enlightenment and the ordinary world are not conceived as antithetical. Still, many contemporary green ideas do not sit well with classical Mahāyāna doctrines. Mahāyāna philosophers coincide in equating ultimate reality with ‘emptiness,’ and propose knowledge of this reality as a final soteriological purpose. Emptiness is generally said to be ineffable, and to involve the negation of all views. An important question is how to reconcile environmentalism with the relinquishing of views. I consider several prevalent themes in environmentalism, including the philosophy of ‘Oneness,’ and other systems that are often compared with Buddhism, like process thought. Many of these turn out to have more in common with an extreme view that Buddhism seeks to avoid, namely, eternalism. I attempt to outline an environmental position that, like the doctrine of emptiness, traverses a Middle Path between eternalism and nihilism. I conclude by proposing that emptiness could be regarded as the source of value in nature, if it is seen in its more positive aspect, as ‘pliancy.’ This would imply that what Buddhist environmentalists should seek to protect is not any being in its current form, nor any static natural system, but the possibility of adaptation and further evolution.

Most restoration projects are designed to approximate the species composition and ecotypes ecologists and historians determine were present in an area at some point in the historical past. In most cases, although somewhat arbitrary, the specific time chosen is based on an understanding of historic species composition and anthropogenic disturbances.Although restoring an area to the estimated, historical vegetation types is widely accepted, the exclusory nature of the restoration process often actively eliminates not just invasive species, but also non-invasive, nonnative species (...) as well as displaced native species. These exclusory activities echo patterns of domination and degradation that led to a need for restoration in the first place. Although the domination present in restoration stems from an earnest desire to repair harms inflicted by human carelessness, it at the same time enforces a human conception of the ideal landscape. Attending to ecofeminist concepts such as inclusivism and pluralism, and embracing their rejection of dualistic thinking and the logic of domination demands an expanded tolerance within the practice of ecological restoration. An expanded ecofeminist conceptualization of restoration, a restorashyn, attempts to reduce the presence of overt human domination of the land. Doing so may ultimately mean that the species composition of an ecofeminist restorashyn will not be purely native, but may instead include a diverse mix of both native and non-invasive, nonnative species.

Kalrnaric. We set out a system T, consisting of normal proofs constructed by means of elegantly symmetrical introduction and elimination rules. In the system T there are two requirements, called ( ) and ()), on applications of discharge rules. T is sound and complete for Kalmaric arguments. ( ) requires nonvacuous discharge of assumptions; ()) requires that the assumption discharged be the sole one available of highest degree. We then consider a 'Duhemian' extension T*, obtained simply by dropping the requirement (...) ()). T* is a proper subsystem of intuitionistic relevant logic. Our main result is that T* is a double negation consistency companion to classical logic. Thus all one needs to add to T* to obtain classical logic is the (intuitionistic) absurdity rule, and the (classical) rule of double nega-. (shrink)
