We attempt to identify and evaluate the association between key characteristics of not-for-profit hospitals and market concentration, as measured by the Herfindahl–Hirschman Index, using data available from the American Hospital Association, the Centers for Medicare and Medicaid Services, and the Internal Revenue Service Form 990. Our goal is to provide decision support to policy makers on factors that contribute to market competitiveness, which has been linked to improvements in efficiency, costs, and access to health care. We find that contributions are (...) positively associated with market concentration. This could indicate that well-run NP hospitals are rewarded both financially as well as with increased market share. We also find that a higher percentage of Medicare patients is positively correlated with market concentration. This could be explained by the fact that Medicare reimbursement rates are generally lower than those paid by private insurers ; thus, hospitals might not necessarily choose to operate in areas with high Medicare populations. Further, median income is negatively associated with market concentration. One explanation for this effect could be the fact that a population with a higher median income is in a better position to pay for services, making them attractive to hospitals as a potential market. Finally, we find that the presence of managers with voting rights on the boards of directors has no significant impact. (shrink)

Israel Scheffler's ground-breaking essay, On Human Potential, deserves to be more widely known among educational policy analysts, especially in light of the popularity in educationist circles of W.E. Deming's organizational philosophy known as Total Quality Management . In what follows,I argue that the heuristical value of Deming's perscriptions are entailed in Scheffler's On Human Potential. More importantly, I argue, where Deming's work falls short, especially in being naive about the human condition, Scheffler's analysis provides a foundation for management theory in (...) education that insures the flourishing of an optimal number of contributing participants. In fashioning these ideas, Scheffler brings pioneering thinking to the emerging fields of management studies generally and educational policy specifically. (shrink)

Paul Weithman offers a fresh, rigorous, and compelling interpretation of John Rawls's reasons for taking his so-called "political turn.".

Extant theoretical work on the political resource curse implies that dependence on resource revenues should decrease autocracies’ likelihood of democratizing but not necessarily affect democracies’ chances of survival. Yet most previous empirical studies estimate models that are ill-suited to address this claim. We improve upon earlier studies, estimating a dynamic logit model that interacts a continuous measure of resource dependence with an indicator of regime type using data from 166 countries, covering the period from 1816-2006. We find that an increase (...) in resource dependence at time t - 1 increases the likelihood of autocratic persistence at t, but has no appreciable effect on democratic survival. We go beyond existing empirical studies to show that increases in resource dependence have persistent and substantial cumulative effects on autocracies' likelihood of becoming democratic over the long-term, showing that the total effect of resource dependence on regime type is much larger than the short-term (one period) effect indicates.

Research on positive psychology demonstrates that specific individual dispositions are associated with more desirable outcomes. The relationship of positive psychological constructs, however, has not been applied to the areas of business ethics and social responsibility. Using four constructs in two independent studies (hope and gratitude in Study 1, spirituality and generativity in Study 2), the relationship of these constructs to sensitivity to corporate social performance (CSCSP) were assessed. Results indicate that all four constructs significantly predicted CSCSP, though only hope and (...) gratitude interacted to impact CSCSP. Discussion focuses upon these findings, limitations of the study, and future avenues for research. (shrink)

In recent years there has been substantial support for heart rate variability biofeedback (HRVB) as a treatment for a variety of disorders and for performance enhancement ( Gevirtz, 2013 ). Since conditions as widely varied as asthma and depression seem to respond to this form of cardiorespiratory feedback training, the issue of possible mechanisms becomes more salient. The most supported possible mechanism is the strengthening of homeostasis in the baroreceptor ( Vaschillo et al., 2002 ; Lehrer et al., 2003 ). (...) Recently, the effect on the vagal afferent pathway to the frontal cortical areas has been proposed. In this article, we review these and other possible mechanisms that might explain the positive effects of HRVB. (shrink)

This symposium begins with a critique by Paul Hirst of Wilfred Carr's ‘Philosophy and Education’(Journal of Philosophy of Education, 2004, 38.1), where Carr argues that philosophy of education should be concerned with ‘practical philosophy’ rather than ‘theoretical philosophy’. Hirst argues that the philosophy of education is best understood as a distinctive area of academic philosophy, in which the exercise of theoretical reason contributes critically to the development of rational educational practices and their discourse. While he acknowledges that these practices (...) and their discourse must of their nature be directly developed in the exercise of practical reason, or phronesis, the notion of ‘practical philosophy’ is rejected as ultimately incoherent and illusory. In his reply to Hirst's critique, Carr identifies three central claims in Hirst's argument and takes issue with each of these. He reaffirms the need to draw upon the resources afforded by the Aristotelian tradition of practical philosophy in order to identify inadequacies in our present understanding of how philosophy is related to education. He suggests that it is only through bringing their own ‘prejudices’ into critical confrontation with this tradition that philosophers of education will be able to assess whether practical philosophy is incoherent and illusory, as Hirst claims, or whether it is indispensable to the future development of their discipline. In a rejoinder to Carr, Hirst, defends the claim that philosophy of education is a social practice concerned with developing justifiable propositional accounts of the conceptual relations, justificatory procedures and presuppositions of educational practices. He rejects the argument that this ‘theoretical philosophy’ approach must be replaced by that of a new ‘practical philosophy’. (shrink)

The paper asks under what conditions deductive reasoning transmits justification from its premises to its conclusion. It argues that both standard externalist and standard internalist accounts of this phenomenon fail. The nature of this failure is taken to indicate the way forward: basic forms of deductive reasoning must justify by being instances of 'blind but blameless' reasoning. Finally, the paper explores the suggestion that an inferentialist account of the logical constants can help explain how such reasoning is possible.

In a wide-ranging study of unusual interest, Paul Weiss, Sterling Professor of Philosophy at Yale University, applies the principles and methods of philosophy to athletics. Every culture, he notes, has games of some kind; few activities seem to interest both children and young men as much as sports do; and few attract so many spectators, rich and poor. Yet none of the great philosophers, claiming to take all knowledge and being as their province, have made more than a passing (...) reference to sport, in part, Professor Weiss suggests, because they thought that what pleased the vulgar was not worth sustained study by the leisured. This seminal book breaks new ground and explores new paths: psychological and sociological forms of human behavior exhibited in games; the physiology of athletics, and the efforts of training and conditioning; and the motivation of athletics—the rhythm and aims of contests and games, and the meaning of team play. More importantly, however, Professor Weiss’s unique contributions lie in his discussions of the distinct contributions that sport makes to civilization. Professor Weiss discusses at length such topics as the Olympic Games and men and women as amateur and pro­fessional athletes—and their sacrifices, defeats, and humilia­tions. And he delineates the stages the athlete must go through in his progress toward self-completion. (shrink)

The aim of appraisal theory in the psychology of emotion is to identify the features of the emotion-eliciting situation that lead to the production of one emotion rather than another². A model of emotional appraisal takes the form of a set of dimensions against which potentially emotion-eliciting situations are assessed. The dimensions of the emotion hyperspace might include, for example, whether the eliciting situation fulfills or frustrates the subject’s goals or whether an actor in the eliciting situation has violated a (...) norm. Richard Lazarus’s well-known model of emotional appraisal has six dimensions, and the regions of the resulting hyperspace that correspond to particular emotions are summarized by Lazarus as the ‘core relational themes’ of those emotions. Anger, for examples, is elicited by the core relational theme ‘a demeaning offence against me and mine’, sadness by ‘having experienced an irrevocable loss’ and guilt by ‘having transgressed a moral imperative’ (Lazarus, 1991).

How should we go about identifying the particular non-semantic property of a given word that is responsible for its meaning? And what sort of property will that turn out to be? The use theory, as I want to develop it, offers answers to these questions. It begins with the observation that the meaning of a word is a common factor in the explanations of its various occurrences and proceeds to argue, on that basis, that each word means what it does (...) in virtue of the acceptance conditions of certain specified sentences containing it. For the sake of concreteness here are some examples of the sort of meaning-constitution claims that may issue from UTM. (shrink)

The recognition of extracellular molecules by cell surface receptors is the principal mechanism used by cells to sense their environment. Consequently, signals transduced as a result of these interactions make a major contribution to the regulation of cellular phenotype. Historically, particular emphasis has been placed on elucidating the intracellular consequences of growth factor and cytokine binding to cells. In addition to these interactions, however, cells are usually in intimate contact with a further source of complex structural and functional information, namely (...) immobilised extracellular matrix and/or cell surface adhesion proteins. A key question in recent years has been whether cells use the myriad of adhesion protein‐receptor interactions purely for structural and migratory function, or whether these interactions also make a more varied contribution to cell phenotype. Here we review dynamic aspects of the function of one major class of adhesion receptor, the integrins. In particular, we focus on the evidence for shape changes in integrin molecules, the mechanisms responsible for regulating ligand binding, and the signals transduced following integrin occupancy.

I explore some of the ways that assumptions about the nature of substance shape metaphysical debates about the structure of Reality. Assumptions about the priority of substance play a role in an argument for monism, are embedded in certain pluralist metaphysical treatments of laws of nature, and are central to discussions of substantivalism and relationalism. I will then argue that we should reject such assumptions and collapse the categorical distinction between substance and property.

The contributors to this volume were asked the following questions: The term "Humanism" is widely used, as are the terms "ethical" Humanism, "scientific" Humanism and "religious" Humanism. What is Humanism? Can you define it? If there is in your judgment no clear definition in the literature, you may wish to propose one. You may also wish to focus on the relationship of Humanism to atheism, science, its ethical position, or some other theme. Those who have contributed represent a wide spectrum (...) of Humanist opinion in the world today. They are primarily philosophers, psychologists, social scientists, ethical and religious leaders. Among the themes they discuss are historic roots of Humanism, the general problem of definition, the relationship of Humanism to ethics and morality, Humanism and religion, Humanism and atheism and Humanism on the world scene. Most of the varieties of Humanism are represented, including naturalistic Humanism, liberal Humanism, atheistic Humanism, humanistic psychology, behaviourism, Marxism, and Zen. If there is a common thread running throughout this volume, it is the conviction that Humanism is committed to the method of reason as the chief means of solving problems and the belief that mankind can survive and humans can enjoy a significant life. This conviction and this belief, however, can be realized only if men continue to have confidence in their own natural powers and abilities and the courage to use them. (shrink)

Let CH be the class of compacta (i.e., compact Hausdorff spaces), with BS the subclass of Boolean spaces. For each ordinal α and pair $\langle K,L\rangle$ of subclasses of CH, we define Lev ≥α K,L), the class of maps of level at least α from spaces in K to spaces in L, in such a way that, for finite α, Lev ≥α (BS,BS) consists of the Stone duals of Boolean lattice embeddings that preserve all prenex first-order formulas of quantifier rank (...) α. Maps of level ≥ 0 are just the continuous surjections, and the maps of level ≥ 1 are the co-existential maps introduced in [8]. Co-elementary maps are of level ≥α for all ordinals α; of course in the Boolean context, the co-elementary maps coincide with the maps of level ≥ω. The results of this paper include: (i) every map of level ≥ω is co-elementary; (ii) the limit maps of an ω-indexed inverse system of maps of level ≥α are also of level ≥α; and (iii) if K is a co-elementary class, k ≥ k (K,K) = Lev ≥ k+1 (K,K), then Lev ≥ k (K,K) = Lev ≥ω (K,K). A space X ∈ K is co-existentially closed in K if Lev ≥ 0 (K, X) = Lev ≥ 1 (K, X). Adapting the technique of "adding roots," by which one builds algebraically closed extensions of fields (and, more generally, existentially closed extensions of models of universal-existential theories), we showed in [8] that every infinite member of a co-inductive co-elementary class (such as CH itself, BS, or the class CON of continua) is a continuous image of a space of the same weight that is co-existentially closed in that class. We show here that every compactum that is co-existentially closed in CON (a co-existentially closed continuum) is both indecomposable and of covering dimension one. (shrink)

A central question in neuroscience and psychology is how the mammalian brain represents the outside world and enables interaction with it. Significant progress on this question has been made in the domain of spatial cognition, where a consistent network of brain regions that represent external space has been identified in both humans and rodents. In rodents, much of the work to date has been done in situations where the animal is free to move about naturally. By contrast, the majority of (...) work carried out to date in humans is static, due to limitations imposed by traditional laboratory based imaging techniques. In recent years, significant progress has been made in bridging the gap between animal and human work by employing Virtual Reality (VR) technology to simulate aspects of real-world navigation. Despite this progress, the VR studies often fail to fully simulate important aspects of real-world navigation, where information derived from self-motion is integrated with representations of environmental features and task goals. In the current review, we provide a brief overview of animal and human imaging work to date, focusing on commonalties and differences in findings across species. Following on from this we discuss VR studies of spatial cognition, outlining limitations and developments, before introducing mobile brain imaging techniques and describe technical challenges and solutions for real-world recording. Finally, we discuss how these advances in mobile brain imaging technology, provide an unprecedented opportunity to illuminate how the brain represents complex multifaceted information during naturalistic navigation.

The emergence of new obstetrical and neonatal technologies, as well as more aggressive clinical management, has significantly improved the survival of extremely low birth weight infants. This development has heightened concerns about the limits of viability. ELBW infants, weighing less than 1,000 grams and no larger than the palm of one's hand, are often described as of late twentieth century technology. Improved survivability of ELBW infants has provided opportunities for long-term follow-up. Information on their physical and emotional development contributes to (...) developing standards of practice regarding their care. (shrink)

In this paper, I present a solution to the Doomsday argument based on a third type of solution, by contrast to, on the one hand, the Carter-Leslie view and, on the other hand, the Eckhardt et al. analysis. I begin by strengthening both competing models by highlighting some variations of their original models, which renders them less vulnerable to several objections. I then describe a third line of solution, which incorporates insights from both Leslie and Eckhardt’s models and fits more (...) adequately with the human situation corresponding to DA. I argue then that this two-sided analogy casts new light on the reference class problem. This leads finally to a novel formulation of the argument that could well be more plausible than the original one. (shrink)

Explanations of cognitive processes provided by traditional artificial intelligence were based on the notion of the knowledge level. This perspective has been challenged by new AI that proposes an approach based on embodied systems that interact with the real‐world. We demonstrate that these two views can be unified. Our argument is based on the assumption that knowledge level explanations can be defined in the context of Bayesian theory while the goals of new AI are captured by using a well established (...) robot based model of learning and problem solving, called Distributed Adaptive Control (DAC). In our analysis we consider random foraging and we prove that minor modifications of the DAC architecture renders a model that is equivalent to a Bayesian analysis of this task. Subsequently, we compare this enhanced, “rational,” model to its “non‐rational” predecessor and a further control condition using both simulated and real robots, in a variety of environments. Our results show that the changes made to the DAC architecture, in order to unify the perspectives of old and new AI, also lead to a significant improvement in random foraging. (shrink)

Paul Elmer More's philosophy was self-styled ‘dualism’, and because developed initially from a student's enthusiasm instigated by a book on Manicheism, has often been misinterpreted. In this paper, on the basis of More's long development, I shall try to survey the nuances of his ‘dualism’ or ‘dualisms’, the various aspects of ‘dualism’ which he developed largely through case studies of thinkers of the past. In a significant way, to parody William James, the Shelburne Essays might well be called ‘The (...) Varieties of Dualistic Experience’, and of course for More ‘dualistic’ was virtually a synonym for ‘religious’. Out of these studies issued a Christian Platonism, or more precisely, a philosophy of the Incarnation, particularly in Christ the Word . The subsequent volume in a series called ‘The Greek Tradition: From the Death of Socrates to the Council of Chalcedon’ is The Catholic Faith . Although More called his dualism ‘absolute’, and it is sometimes presented as ‘absolute dualism’, the ‘sacramental idea’ at the heart of Christianity is said to rest ‘ultimately upon a dualistic conception of the world, in accordance with which matter and spirit are essentially distinct yet mutually interdependent. It implies on the one side that matter can be indefinitely adapted to spiritual uses, and on the other side that spirit requires now, and, so far as our knowledge and imagination reach, will always require the aid of some sort of corporeal instruments. It points to a divine purpose unfolding itself in a continuous process wherein the stuff of existence is…transmuted into an ever finer medium of order and beauty and righteousness and joy. (shrink)

Mindfulness, derived from Buddhist psychology and philosophy, has gained broad popularity in the last decades, due importantly to scientific interest and findings. Yet Buddhist mindfulness developed in Asian pre-scientific culture and religion, and is predicated upon long-term cultivation of introspective awareness of lived experience, not highly accessible to empirical study. Further complicating the ‘science' of mindfulness, mindfulness's very definition is multifaceted, resistant to dismantling and requires substantial amounts of personal practice to gain expertise. Most scientists investigating mindfulness have not achieved (...) a high level of this expertise. Here I address how mindfulness is currently being invented as a scientific fact or object of inquiry. The intrinsic porosity of subjective and objective factors influencing the investigation of mindfulness is highlighted: the evolving body of ‘scientific' experts, instruments used to measure mindfulness, the alliances of funders and other supporters of mindfulness research, and the public representation of the related findings.
