Surgeons have an ethical obligation to ensure all patients, regardless of their personal characteristics, receive the same quality of care. Established surgeons also have an obligation to ensure equal treatment for their peers and for those who would like to join the field. The commitment to ethical hiring and working standards entails making certain all individuals have the same opportunities free from discriminatory practices. The world of business has long realized the positive implications of having a diverse and inclusive workforce. (...) Studies have shown a positive correlation between increased racial and gender diversity and company performance. Diversity can lead to an increase in knowledge by sharing ideas with individuals who come from different life experiences and breakdown cultural barriers. We have already begun to see the impact of ignoring the importance of diversity within healthcare, including surgery. Healthcare disparities are defined by the NIH as “differences in the incidence, prevalence, mortality, and burden of diseases and other adverse health conditions that exist among specific population groups.” Healthcare disparities persist despite decades acknowledging their existence, and they are pernicious and prevalent in surgery. One proposed method to help reduce or eliminate healthcare disparities is to increase the diversity of the workforce treating the patients, which would in turn reduce potential bias the patients face in the healthcare setting. Implicit bias can play a key role in interactions with patients and colleagues and needs to be explored on an individual basis. Cultural competence training can also provide surgeons the ability to effectively communicate with not only a diverse population of patients but also a diverse surgical workforce. All surgeons regardless of their role can have a positive impact on diversity as it relates to patient care and the surgical workforce. (shrink)

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

John Haugeland aimed throughout his career to determine what it is for an entity to count as having intelligence or thought, and at each stage he developed the idea from the phenomenological tradition that genuine thought requires intentionality. His most mature essay to do this, “Authentic Intentionality,” shows how the intentional directedness of thought requires that thinkers understand themselves as responsive to entities they think about, that they be committed to maintaining the socially shared forms of understanding of those entities, (...) and yet that they be self-critically open to the possibility of needing to revise or reject those forms of understanding. In this essay I argue that, while Haugeland’s account of intentionality sheds much light on empirical thought (thought directed at different kinds of things in the world), it doesn’t address what it takes for thought to intend or think its own form—and so it fails to describe the kind of transcendental thought of which the account itself is an instance. Building on Haugeland’s own rich picture of self-understanding, I show how we can remedy this omission, and that when we do, we see that transcendental thought is performed by each of us as concrete individuals and yet takes place from a perspective outside of, and thus free from, the normative demands and existential situations of our empirical lives. It is thus of at most therapeutic use in them, even as it is valuable for its own sake as an exercise of our finite freedom. (shrink)

One of the characteristics that define us as Dasein, according to Heidegger, is that our being is at issue for us. Most readers interpret this to mean that we each, as individuals situated in the world with others, face the questions of who, how, and whether to be within our unique situations. Yet what Heidegger identifies as Dasein’s being is a general structure—care—that is the same for all individuals. Adapting and modifying John Haugeland’s account of understanding as projecting entities upon (...) their constitutive ontological possibilities, I argue that it is this general, ontological structure that Heidegger means to say is at issue for us, and that understanding ourselves in terms of it is a condition of possibility of understanding ourselves as particular individuals faced with the questions of who, how, and whether to be in our respective situations. I then show how this allows us to begin to address Heidegger’s view of the role philosophy plays in an individual’s existence as it makes explicit the ontological structure which she normally only tacitly understands. (shrink)

I begin with a brief exposition of what is positive in Haugeland's interpretation of Heidegger. At the same time, I show how Haugeland subtly shifts the ground so as to make it possible to read into the texts his own idea that being is the entity-beholden, variable, normative basis for ways of life. I then argue that what Heidegger himself says about the being of available (zuhanden) entities, i.e., things of use or equipment (Zeug), doesn’t fit with Haugeland’s normativity-oriented account. (...) I develop this argument further through a look at Heidegger’s treatment of occurrent (vorhanden) nature as he elaborates that in his reading of Kant. This allows us to see how Heidegger follows Kant in thinking of the forms of being as spontaneous but non-arbitrary creations we produce for ourselves via what Kant called imagination, which activity Heidegger takes to be the self-temporalizing of Dasein identified but only opaquely described in SZ. From there, I show how we might generalize from Heidegger’s Kant’s treatment of the occurrent to a broader account in which other regional understandings of being, including that of the available, may also be understood as emerging from our temporalizing/imaginative activity. This shows what Heidegger’s overall project of fundamental ontology looks like, and how it could be completed in a way he himself didn't, if an understanding of being is an understanding of forms not norms.

With the exception of solidity, Locke's list of primary qualities matches his list of ideas of "divers senses," that is, ideas that are perceived in multiple sensory modalities. I argue that for these ideas, the fact that they are robust in our sensory experience in a way that single-modality ideas are not provides the main reason for taking them to be ideas of primary qualities. Solidity, however, is taken as primary because it is ineliminable from experience in a way that (...) other ideas are not, and because the multiply-sensed ideas are all tied to it. Since solidity is experienced through touch, Locke is thus offering us an account of primary quality perception grounded in our embodied interaction with the world. (shrink)

Although Glowacki proposed that peace developed from the relatively recent advent of intergroup norms and tolerance for out-group members, we submit that (a) positive intergroup relations developed from a psychology grounded in the regulation of intragroup relations, (b) the “default” intergroup orientation is uncertainty, and (c) positive intergroup relations likely existed early in our evolutionary history.

Against the background of a recent exchange between Cristina Lafont and Hubert Dreyfus, I argue that Heidegger's method of ?formal indication? is at the heart of his attempt in Sein und Zeit to answer ?the ontological question of the being of the ?sum?? (SZ, p. 46). This method works reflexively, by picking out certain essential features of one's first-person singular being at the outset of its investigation that are implicit in the question ?what is it to be the entity I (...) am?? On the basis of these features, various further a priori, ontological structures (care and temporality) that constitute one as a first-person singular entity then become accessible. Formal indication is thus formal in two senses: it officially designates or signals certain first-person singular phenomena as the topic of investigation, and it picks out features which define the ontological form of the entity in question. It is thereby the method by which a legitimately transcendental account of our being may be begun to be generated by each of us from out of our factical, immanent existence. (shrink)

Heidegger’s early project aims to articulate the form of our being as Dasein, and he says that for this usually hidden form to become accessible, a certain kind of “mood” is required of the philosopher. This “ground-mood” he identifies in Sein und Zeit as anxiety. He also, however, presents anxiety as a mood anyone, philosopher or not, experiences when there is some significant breakdown in the living of her life. I argue here that there are largely unrecognized problems with this (...) conflation of methodological and “existential” moods, but that there is nevertheless a compelling methodological account of anxiety that can be teased apart from the existentialist one: methodologically understood, anxiety is a self-affected state of the ontologist, one that results from her asking ontological questions of herself, and, by imagining crisis or breakdown, withdrawing from her determinate situation to a position where she can see the form of her own activity as questioner and imaginer. I draw out some consequences this has for how we should understand the place of ontological understanding in living one’s life, and I conclude by briefly showing how my reading helps us see Heidegger as developing key elements in the work of Descartes and Kant.

Abstract: Heidegger's Sein und Zeit (SZ) is commonly viewed as one of the 20th century's great anti-Cartesian works, usually because of its attack on the epistemology-driven dualism and mentalism of modern philosophy of mind or its apparent effort to ‘de-center the subject’ in order to privilege being or sociality over the individual. Most who stress one or other of these anti-Cartesian aspects of SZ, however, pay little attention to Heidegger's own direct engagement with Descartes, apart from the compressed discussion in (...) SZ§§19–21. I here show through a careful reading of Heidegger's lectures on Descartes from the years immediately preceding SZ that, while he has sharp criticisms of Descartes and certain ‘Cartesian’ aspects of modern philosophy along the lines commonly recognized, he also aims to disclose what he calls the ‘positive possibilities’ in Descartes and the philosophy he inspired. I detail a number of these and then show that they force us to see Heidegger's own early project as largely unconcerned with dualism and mentalism per se, and much more with questions of the philosophical methodology that gives rise to them. Moreover, I show that a careful reading of Heidegger's treatment of the cogito makes clear that he is no serious way attempting to ‘de-center the subject’ and that the fundamental question of the ‘analytic of Dasein’ is one that takes Descartes as an immediate jumping off point: how can I articulate what I understand myself to be as the general kind of entity I am, and on what besides me does my being depend?

Evolution - both the fact that it occurred and the theory describing the mechanisms by which it occurred - is an intrinsic and central component in modern biology. Theodosius Dobzhansky captures this well in the much-quoted title of his 1973 paper 'Nothing in biology makes sense except in the light of evolution'. The correctness of this assertion is even more obvious today: philosophers of biology and biologists agree that the fact of evolution is undeniable and that the theory of evolution (...) explains that fact. Such a theory has far-reaching implications. In this volume, eleven distinguished scholars address the conceptual, metaphysical and epistemological richness of the theory and its ethical and religious impact, exploring topics including DNA barcoding, three grand challenges of human evolution, functionalism, historicity, design, evolution and development, and religion and secular humanism. The volume will be of great interest to those studying philosophy of biology and evolutionary biology. (shrink)

Cristina Lafont's recent reading of Heidegger offers a powerful formulation of the widespread view that once one recognizes our `facticity' and the role of language in shaping it, there is no room left to talk about transcendental structures of meaning or experience. In this article I challenge this view. I argue that Lafont inaccurately conflates what Heidegger calls our `understanding of being' with that which language discloses. In order to show that the philosophical motivation for this conflation is unsound, I (...) also argue that Lafont's own positive theory of meaning itself tacitly assumes a distinction between factical and transcendental, and so rests on exactly what she finds problematic in Heidegger. This still leaves a puzzle as to how factical individuals are actually able to grasp anything transcendental, so I conclude by sketching Heidegger's method of `formal indication', which is meant to show precisely how this can be done.

The spacing effect is among the most widely replicated empirical phenomena in the learning sciences, and its relevance to education and training is readily apparent. Yet successful applications of spacing effect research to education and training is rare. Computational modeling can provide the crucial link between a century of accumulated experimental data on the spacing effect and the emerging interest in using that research to enable adaptive instruction. In this paper, we review relevant literature and identify 10 criteria for rigorously (...) evaluating computational models of the spacing effect. Five relate to evaluating the theoretic adequacy of a model, and five relate to evaluating its application potential. We use these criteria to evaluate a novel computational model of the spacing effect called the Predictive Performance Equation. Predictive Performance Equation combines elements of earlier models of learning and memory including the General Performance Equation, Adaptive Control of Thought—Rational, and the New Theory of Disuse, giving rise to a novel computational account of the spacing effect that performs favorably across the complete sets of theoretic and applied criteria. We implemented two other previously published computational models of the spacing effect and compare them to PPE using the theoretic and applied criteria as guides. (shrink)

To function well in an unpredictable environment using unreliable components, a system must have a high degree of robustness. Robustness is fundamental to biological systems and is an objective in the design of engineered systems such as airplane engines and buildings. Cognitive systems, like biological and engineered systems, exist within variable environments. This raises the question, how do cognitive systems achieve similarly high degrees of robustness? The aim of this study was to identify a set of mechanisms that enhance robustness (...) in cognitive systems. We identify three mechanisms that enhance robustness in biological and engineered systems: system control, redundancy, and adaptability. After surveying the psychological literature for evidence of these mechanisms, we provide simulations illustrating how each contributes to robust cognition in a different psychological domain: psychomotor vigilance, semantic memory, and strategy selection. These simulations highlight features of a mathematical approach for quantifying robustness, and they provide concrete examples of mechanisms for robust cognition. (shrink)

The authors' proposal for the evolutionary origins of historical myths does not hold up to scrutiny, as illustrated by a simple mathematical model. Group-level explanations, such as defining the conditions for in-group membership, are dismissed by the authors but are far more plausible, as illustrated by the ongoing war in Ukraine.

Looking at the breadth of Joan Didion's writing - from journalism, essays, fiction, memoir and screen plays - it may appear that there is no unifying thread, but in this original exploration of her work Matthew R. McLennan argues that 'the ethics of memory' - the question of which norms should guide public and private remembrance - offers a promising vision of what is most characteristic and salient in Didion's works. By framing her universe as indifferent and essentially precarious, (...) McLennan demonstrates how this outlook guides Didion's reflections on key themes linked to memory: namely witnessing and grieving, nostalgia, and the paradoxically amnesiac qualities of our increasingly archived public life that she explored in famous texts like Slouching Towards Bethlehem, The Year of Magical Thinking and Salvador. McLennan moves beyond the interpretive value of such an approach and frames Didion as a serious, iconoclastic philosopher of time and memory. Through her encounters with the past, the writer is shown to offer lessons for the future in an increasingly perilous and unsettled world. (shrink)

This book provides a focus for future discussion in one of the most important debates within historical theology within the protestant tradition - the debate about the definition of a category of analysis that operates over five centuries of religious faith and practice and in a globalising religion. In March 2009, TIME magazine listed ‘the new Calvinism’ as being among the ‘ten ideas shaping the world.’ In response to this revitalisation of reformation thought, R. Scott Clark and D. G. Hart (...) have proposed a definition of ‘Reformed’ that excludes many of the theologians who have done most to promote this driver of global religious change. In this book, the Clark-Hart proposal becomes the focus of a debate. Matthew Bingham, Chris Caughey, and Crawford Gribben suggest a broader and more historically responsible definition for ‘Reformed,’ as Hart and Scott respond to their arguments. (shrink)

Most philosophical defences of the state’s right to exclude immigrants derive their strength from the normative importance of self-determination. If nation-states are taken to be the political institutions of a people, then the state’s right to exclude is the people’s right to exclude – and a denial of this right constitutes an abridgement of self-determination. In this paper, I argue that this view of self-determination does not cohere with a group-agency view of nation-states. On the group-agency view that I defend, (...) a nation-state is the kind of group-agent that does not supervene on the intentionality of member/citizens. If we think that a nation-state is an intentional group-agent in its own right, then we should think that self-determination resides with the institutions of the state rather than with the citizens. If nation-states do not supervene on the intentionality of citizens, then it is unclear why citizens might have the right to control membership in the state as a feature of self-determination.

Conspiracy theories are a popular topic of conversation in everyday life but are often frowned upon in academic discussions. Looking at the recent spate of philosophical interest in conspiracy theories, The Philosophy of Conspiracy Theories looks at whether the assumption that belief in conspiracy theories is typically irrational is well founded. -/- The Philosophy of Conspiracy Theories is aimed at both the philosopher and the non-philosopher. It is a qualified defence of belief in conspiracy theories: belief in conspiracy theories can (...) be rational in some circumstances. It covers such issues as: who might be considered a qualified conspiracy theorist; how do we analyse claims of disinformation; is our reliance on official theories a good reason to be suspicious of rival conspiracy theories; and what should we do when official theories and conspiracy theories are in conflict? -/- Matthew Dentith is a New Zealand-based philosopher whose research includes analyses of why we have grounds to be suspicious of official theories, the reliability of the transmission of rumours, and the role of trust in the acceptance of theories.

History, Philosophy and Science Teaching argues that science teaching and science teacher education can be improved if teachers know something of the history and philosophy of science and if these topics are included in the science curriculum. The history and philosophy of science have important roles in many of the theoretical issues that science educators need to address: the goals of science education; what constitutes an appropriate science curriculum for all students; how science should be taught in traditional cultures; what (...) integrated science is; how scientific literacy can be promoted; and the conflict which can occur between science curriculum and deep-seated religious or cultural values and knowledge. In part, answers to these questions hinge on views about the nature of science, views that are best informed by historical and philosophical study. Outlining the history of liberal, or contextual, approaches to the teaching of science, Michael Matthews elaborates contemporary curriculum developments that explicitly address questions about the nature and the history of science. He provides examples of classroom teaching and develops useful arguments on constructivism, multicultural science education and teacher education. The book will appeal to school and university science teachers, educators of science teachers, and historians and philosophers of science. (shrink)

Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing of symbolic fractions. Participants completed modified Stroop tasks in which they selected the larger of two symbolic fractions while the ratios of the fonts in which the fractions were printed and the overall sizes of the (...) compared fractions were manipulated as irrelevant dimensions. Participants were slower and less accurate when nonsymbolic dimensions of printed fractions were incongruent with the symbolic comparison decision. Results indicated a robust basic sensitivity to nonsymbolic ratios that exceeds prior conceptions about the accessibility of fraction values. Results also indicated a congruity effect for overall fraction size, contrary to findings of prior research. These findings have implications for extending theory about the nature of human number sense and mathematical cognition more generally. (shrink)

Conspiracy theories are typically thought to be examples of irrational beliefs, and thus unlikely to be warranted. However, recent work in Philosophy has challenged the claim that belief in conspiracy theories is irrational, showing that in a range of cases, belief in conspiracy theories is warranted. However, it is still often said that conspiracy theories are unlikely relative to non-conspiratorial explanations which account for the same phenomena. However, such arguments turn out to rest upon how we define what gets counted (...) both as a ‘conspiracy’ and a ‘conspiracy theory’, and such arguments rest upon shaky assumptions. It turns out that it is not clear that conspiracy theories are prima facie unlikely, and so the claim that such theories do not typically appear in our accounts of the best explanations for particular kinds of events needs to be reevaluated.
