Attentional focus is an area that has garnered considerable attention in the sport psychology and motor performance literature. This is unsurprising given that attentional focus has been directly linked to performance outcomes and is susceptible to coaching input. While research has amassed supporting benefits of an external focus of attention on motor performance using verbal instruction, other studies have challenged the notion that an EFA is more beneficial than an internal focus of attention for sport-related performance. Further, it is unclear (...) what type of instructions may serve to direct an athlete to an EFA and, in particular, if coaching can utilize imagery to orient an athlete toward an EFA. In the present exploratory study, we evaluate the effectiveness of instruction to improve free-throw shooting performance with an emphasis on an EFA brought about by implementing techniques borrowed from the imagery literature. This was tested relative to an alternate approach with an IFA induced through an emphasis on technique, devised to more closely resemble input typical of coach-to-athlete instruction. Twenty-five male and female university basketball players completed both conditions in a fully counterbalanced within-subject design. Results confirmed that participants in the EFA imagery condition had greater shooting accuracy than in the IFA technique condition. The study provides initial evidence that EFA coaching can borrow from imagery techniques, though future research should elucidate the underlying mechanisms of the effect. (shrink)

ONE OF THE MOST prominent theorists of anarcho-capitalism is Hans- Hermann Hoppe. In what is perhaps his most famous result, the argumentation ethic for libertarianism, he purports to establish an a priori defense of the justice of a social order based exclusively on pri- vate property. Hoppe claims that all participants in a debate must presuppose the libertarian principle that every person owns himself, since the principle underlies the very concept of argumentation. Some libertarians (e.g., Rothbard 1988) have celebrated Hoppe’s (...) argument as the final nail in the coffin for collectivism of any type; following Hoppe, they believe that to deny the libertarian ethic is not only wrong, but also internally contradictory. On the other hand, a number of other prominent libertarians characterized Hoppe’s initial statement of his case as “one muddle after another” (Steele 1988, p. 47) or “a tissue of bald assertions” (Yeager 1988, p. 45).

Background: Medical tourism involves patients travelling internationally to receive medical services. This practice raises a range of ethical issues, including potential harms to the patient's home and destination country and risks to the patient's own health. Medical tourists often engage the services of a facilitator who may book travel and accommodation and link the patient with a hospital abroad. Facilitators have the potential to exacerbate or mitigate the ethical concerns associated with medical tourism, but their roles are poorly understood. -/- (...) Methods: 12 facilitators were interviewed from 10 Canadian medical tourism companies. -/- Results: Three themes were identified: facilitators' roles towards the patient, health system and medical tourism industry. Facilitators' roles towards the patient were typically described in terms of advocacy and the provision of information, but limited by facilitators' legal liability. Facilitators felt they played a positive role in the lives of their patients and the Canadian health system and served as catalysts for reform, although they noted an adversarial relationship with some Canadian physicians. Many facilitators described personally visiting medical tourism sites and forming personal relationships with surgeons abroad, but noted the need for greater regulation of their industry. -/- Conclusion: Facilitators play a substantial and evolving role in the practice of medical tourism and may be entering a period of professionalisation. Because of the key role of facilitators in determining the effects of medical tourism on patients and public health, this paper recommends a planned conversation between medical tourism stakeholders to define and shape facilitators' roles.

This volume centers on debates about how far moral judgments bind across traditions and epochs. Nowadays such debates appear especially volatile, both in popular culture and intellectual discourse: although there is increasing agreement that the moral and political criteria invoked in human rights documents possess cross-cultural force, many modern and postmodern developments erode confidence in moral appeals that go beyond a local consensus or apply outside a particular community. Often the point of departure for discussion is the Enlightenment paradigm of (...) a common morality, in which it is assumed that certain unchanging beliefs inhere in the structure of human reason. Whereas some thinkers continue to defend this paradigm, others modify it in diverse ways without abandoning entirely the attempt to address a universal audience, and still others jettison virtually all of its distinguishing features. Exhibiting a range of positions Western participants take in these debates, this volume seeks to advance the substance of the debates themselves without prejudging the outcome. Rival assessments of the Enlightenment paradigm are offered from various philosophical and theological points of view. In addition to the editors, the contributors include Robert Merrihew Adams, Annette C. Baier, Alan Donagan, Margaret A. Farley, Alan Gewirth, David Little, Richard Rorty, Jeffrey Stout, and Lee H. Yearley. (shrink)

The question of the existence of intelligent life on other worlds has never been a purely scientific one. Philosophical, religious and literary issues have been intertwined with scientific ones throughout the history of the “plurality of worlds” debate. This collection of papers in –Studies in History and Philosophy of Science– explores the interrelation of science, philosophy, religion and literature in debates about extraterrestrial life.

The preparation of layers of amorphous Se by plasma-enhanced CVD using the hydride H2Se as precursor gas is described. Information concerning the structure of the films was obtained from Raman spectroscopy. The spectra of amorphous Se indicated that the dominant molecular structure is the eight-membered ring and/or a chain with Se8 molecular fragments. This material exhibited reversible photodarkening when illuminated at 77 K. In order to explain this phenomenon, we propose a mechanism which takes into account the role of the (...) lone-pair electron orbitals of Se in their contribution to structural ordering. Illumination can cause a distortion in the normal bonding direction between nearest-neighbour Se atoms and induce in this way intrinsic defect states located at the band edges. In the photo-darkened state, optical transition will occur between these defect states. (shrink)

This volume has a two-fold purpose: reference and research. As a work of reference, it is designed to provide accessible, objective, and accurate summaries of contemporary developments within the problem of evil. As a work of research, it is designed to advance the dialectic within the problem of evil by offering novel insights, criticisms and responses from top scholars in the field. As such, the volume will serve as a guide to both specialists within the philosophy of religion and nonspecialists (...) alike. Each section of the book opens with an historical essay that frames the essays that follow in a rich historical context. The volume is subdivided into three parts. Part one sketches various “Problems of Evil,” particularly those that have morphed into arguments for atheism. Part two includes responses to problems of evil that go some way towards explaining why our world would have certain evils in it on the assumption that it was created by God. Part three includes responses to evil that admit no explanation for the evils in our world but insist that the problem of evil is not an evidential problem for theists nonetheless. In other words, part two includes theodicies, and part three includes various skeptical replies including defenses and skeptical theism. (shrink)

Stable heavy isotopes co‐exist with their lighter counterparts in all elements commonly found in biology. These heavy isotopes represent a low natural abundance in isotopic composition but impose great retardation effects in chemical reactions because of kinetic isotopic effects (KIEs). Previous isotope analyses have recorded pervasive enrichment or depletion of heavy isotopes in various organisms, strongly supporting the capability of biological systems to distinguish different isotopes. This capability has recently been found to lead to general decline of heavy isotopes in (...) metabolites during yeast aging. Conversely, supplementing heavy isotopes in growth medium promotes longevity. Whether this observation prevails in other organisms is not known, but it potentially bears promise in promoting human longevity. (shrink)

Both unipolar and bipolar depression have been linked with impairments in executive functioning. In particular, mood symptom severity is associated with differences in common EF, a latent measure of general EF abilities. The relationship between mood disorders and EF is particularly salient in adolescence and young adulthood when the ongoing development of EF intersects with a higher risk of mood disorder onset. However, it remains unclear if common EF impairments have associations with specific symptom dimensions of mood pathology such as (...) blunted positive affect, mood instability, or physiological arousal, or if differences in common EF more broadly relate to what is shared across various symptom domains, such as general negative affect or distress. To address this question, bifactor models can be applied to simultaneously examine the shared and unique contributions of particular mood symptom dimensions. However, no studies to our knowledge have examined bifactor models of mood symptoms in relation to measures of common EF. This study examined associations between common EF and general vs. specific symptom dimensions using structural equation modeling in adolescents and young adults with varying severity of mood symptoms. A General Depression factor capturing shared variance across symptoms statistically predicted lower Common EF. Additionally, a factor specific to physiological arousal was associated with lower Common EF. Anhedonia-specific and Mania-specific factors were not significantly related to Common EF. Altogether, these results indicate that deficits in common EF are driven by, or reflect, general features of mood pathology that are shared across symptom dimensions but are also specifically associated with physiological arousal.

Is evil evidence against the existence of God? Even if God and evil are compatible, it remains hotly contested whether evil renders belief in God unreasonable. The Evidential Argument from Evil presents five classic statements on this issue by eminent philosophers and theologians and places them in dialogue with eleven original essays reflecting new thinking by these and other scholars. The volume focuses on two versions of the argument. The first affirms that there is no reason for God to permit (...) either certain specific horrors or the variety and profusion of undeserved suffering. The second asserts that pleasure and pain, given their biological role, are better explained by hypotheses other than theism. -/- Contributors include William P. Alston, Paul Draper, Richard M. Gale, Daniel Howard-Snyder, Alvin Plantinga, William L. Rowe, Bruce Russell, Eleonore Stump, Richard G. Swinburne, Peter van Inwagen, and Stephen John Wykstra. (shrink)

On doxastic theories of propositional faith,necessarily,S has faith that p only if S believes that p. On nondoxastic theories of propositional faith, it’s false that,necessarily,S has faith that p only if S believes that p. In this article, I defend three arguments for nondoxastic theories of faith and I respond to published criticisms of them.

Does faith that p entail belief that p? If faith that p is identical with belief that p, it does. But it isn’t. Even so, faith that p might be necessarily partly constituted by belief that p, or at least entail it. Of course, even if faith that p entails belief that p, it does not follow that faith that p is necessarily partly constituted by belief that p. Still, showing that faith that p entails belief that p would be (...) a significant step in that direction. Can we take that step? In this essay, I assess, and reject, seven reasons to think we can. Along the way, I discuss having faith in a person, being a person of faith, believing something by faith, and believing a person. (shrink)

This essay is a detailed study of William P. Alston’s view on the nature of Christian faith, which I assess in the context of three problems: the problem of the skeptical Christian, the problem of faith and reason, and the problem of the trajectory. Although Alston intended a view that would solve these problems, it does so only superficially. Fortunately, we can distinguish Alston’s view, on the one hand, from Alston’s illustrations of it, on the other hand. I argue that, (...) although Alston’s view only superficially solves these problems, Alston’s illustrations of it suggest a substantive way to solve them, a way that I sketch briefly. (shrink)

Reprinted in Philosophy of Religion: An Anthology, Wadsworth 2015, 6th edition, eds Michael Rea and Louis Pojman. What is propositional faith? At a first approximation, we might answer that it is the psychological attitude picked out by standard uses of the English locution “S has faith that p,” where p takes declarative sentences as instances, as in “He has faith that they’ll win”. Although correct, this answer is not nearly as informative as we might like. Many people say that there (...) is a more informative answer. They say that, at the very least, propositional faith requires propositional belief. More precisely, they say that faith that p requires belief that p or that it must be partly constituted by belief that p. This view is common enough; call it the Common View. I have two main aims in this paper: (i) to exhibit the falsity of the Common View and the paucity of reasons for it, and (ii) to sketch a more accurate and comprehensive account of what propositional faith is.

Reprinted in Philosophical and Theological Essays on the Trinity, Oxford, 2009, eds Michael Rea and Thomas McCall. In this essay, I assess a certain version of ’social Trinitarianism’ put forward by J. P. Moreland and William Lane Craig, ’trinity monotheism’. I first show how their response to a familiar anti-Trinitarian argument arguably implies polytheism. I then show how they invoke three tenets central to their trinity monotheism in order to avoid that implication. After displaying these tenets more fully, I argue (...) that Trinitarians would do well to hold Moreland’s and Craig’s trinity monotheism at arms length. (shrink)

BonJour argues that there can be no basic empirical beliefs. But premises three and four jointly entail ‘BonJour’s Rule’ — one’s belief that p is justified only if one justifiably believes the premises of an argument that makes p highly likely — which, given human psychology, entails global skepticism. His responses to the charge of skepticism, restricting premise three to basic beliefs and noting that the Rule does not require ‘explicit’ belief, fail. Moreover, the Rule does not express an epistemic (...) duty. Finally, his argument against this fails since it is false that if an experiential state has representational content, then it is in need of justification. I venture the diagnosis that BonJour mistook the representational content of a cognitive state for the assertive functional role of a belief. Foundationalism may well be false, but not for BonJour’s reasons. (shrink)

This essay critically examines a questionable presupposition of contemporary science—that science is an instrumental means to human ends and as such is a value- neutral project. According to this presupposition, the responsibility for the ethical evaluation of science concerns only the uses to which science is put by society and thus does not belong properly to the scientific profession. This view, which C. P. Snow called “the myth of ethical neutrality,” is critiqued along ethical, philosophical, and theological axes of analysis. (...) Once we recognize that science is essentially a form of power, it becomes clear that science is morally ambiguous because the power over nature that science enables contains the potential for domination over humanity. From the Christian perspective, which holds that all worldly power is “fallen,” it is evident that science also is in need of being “ransomed” from evil uses and reoriented toward the priorities of God’s Kingdom. Accordingly, to be responsible science must be accountable to transcendent values and must be in dialogue with other disciplines, including ethics, philosophy, and theology. (shrink)

Abstract:Gene editors such as CRISPR could be used to create stronger, faster, or more resilient nonhuman animals. This is of keen interest to people who breed, train, race, and profit off the millions of animals used in sport that contribute billions of dollars to legal and illegal economies across the globe. People have tried for millennia to perfect sport animals; CRISPR proposes to do in one generation what might have taken decades previously. Moreover, gene editing may facilitate enhancing (...) animals’ capacities beyond their typical limits. This paper describes the state of animal use and engineering for sport, examines the moral status of animals, and analyzes current and future ethical issues at the intersection of animal use, gene editing, and sports. We argue that animal sport enthusiasts and animal welfarists alike should be concerned about the inevitable use of CRISPR in sport animals. Though in principle CRISPR could be used to improve sport animals’ well-being, we think it is unlikely in practice to do so. (shrink)

It is ironic that, with few exceptions, the now vast body of critical literature about Diego Velázquez’s Las Meninas fails to link knowledge to understanding—fails to relate the encyclopedic knowledge we have acquired of its numerous details to a convincing understanding of the painting as a whole. Las Meninas is imposing and monumental; yet a large portion of the literature devoted to it considers only its elements: aspects of its nominal subjects, their biographies, and their roles in the household of (...) the queen or the king. Niceties of court etiquette; concerns about clothing, and shoes , and the small cup of water offered to the Infanta Margarita .This increasingly intimate discussion of the painting’s details is not altogether beside the point; some of this information deserves to be integrated into descriptions of the painting as a whole. But a reader of these descriptive accounts soon begins to suspect they are offered in the hope that some new details might provoke an understanding of the entire painting, might prove to be the key to our comprehension of it. In fact, Las Meninas invites such analysis. Some nineteenth-century critics called it “photographic” in its naturalism , in the profusion of its detail, and in the alleged “snapshot” quality of its composition.1 The underlying motive of this understanding ought not to be dismissed, even thought the photography analogy is clearly grotesque, in terms both of history and visual sensibility. Although we know a great deal about the contention, in seventeenth-century Spanish art theory, that a major function of art is the perfecting of nature according to ideal standards, Las Meninas nonetheless is most commonly taken to be a pure spectacle memorializing an incidental moment, seemingly explicable solely in terms of what is apparent in it. 1.

The heme‐containing cytochromes P‐450 are a ubiquitous family of monooxygenase isozymes responsible for the oxidative metabolism of a wide variety of endogenous as well as exogenous compounds. Many of the compounds metabolized by this enzyme system are effectively detoxified and converted to derivatives more easily eliminated from the organism. However, some compounds can be activated to reactive species capable of eliciting a cascade of toxic lesions, including cancer. Since its discovery nearly 30 years ago, the cytochrome P‐450 enzyme system has (...) received a great deal of attention, particularly in the areas of their mechanisms of metabolism, range of substrate specificity, the purification and characterization of the multiple isozymes and, more recently, the regulation of expression of specific forms. This review will discuss current notions concerning the expression of at least one cytochrome P‐450 isozyme and future directions that should lead to a more complete understanding of cytochrome P‐450 gene expression in general, particularly as it impacts upon biochemical pharmacology.

Clinical gene transfer research has both a unique history and a complex and layered system of research oversight, featuring a unique review body, the Recombinant DNA Advisory Committee. This paper briefly describes the process of decision-making about clinical GTR, considers whether the questions, problems, and issues raised in clinical GTR are unique, and concludes by examining whether the RAC's oversight is a useful model that should be reproduced for other similar areas of clinical research.Clinical GTR is governed by the (...) same oversight system as most clinical trials, with a significant addition: the RAC. Like other research with human subjects, GTR, if it is affiliated with a federally funded institution, must be approved by an institutional review board whose activities are governed by the common rule, that is, the federal regulations for protection of human subjects in research. Like other research intended to produce a drug, device, or biologic to be marketed in the United States, GTR is also overseen by the Food and Drug Administration. (shrink)

Children's competence to refuse or consent to medical treatment or surgery tends to be discussed in terms of the child's ability or maturity. This paper argues that the social context also powerfully influences the child's capacity to consent. Inner attributes and external influences are discussed using an analogy of the genes and the stars.

Behavioural phenotypes have been explained by genetic and environmental factors (E) and their interaction. Here we suggest a rethinking of the E factor. Passively incurred environmental influences (E pass) and actively copied information and behaviour (E act) may be distinguished at shared and non-shared level. We argue that E act underlies mutation and selection and is the base of gene-independent heritability.
