In his book, The Principles of Mathematics , the young Bertrand Russell abandoned the common-sense notion that the whole must be greater than its part, and argued that wholes and their parts can be similar, e.g. where both are infinite series, the one being a sub-series of the other. He also rejected the popular view that the idea of an infinite number is self-contradictory, and that an infinite set or collection is an impossibility. In this paper, I intend to re-examine (...) Russell's wisdom in doing both these things, and see if it might not have made more sense, and caused his enterprise fewer problems, if he had simply stuck to our commonplace ideas. To this end, I shall also be considering his treatment of certain paradoxes that he claims can only be resolved by the abandonment of the above notions, as well as certain others which his theories appear to have generated.

Recall that a group G has finitely satisfiable generics (fsg) or definable f-generics (dfg) if there is a global type p on G and a small model $M_0$ such that every left translate of p is finitely satisfiable in $M_0$ or definable over $M_0$, respectively. We show that any abelian group definable in a p-adically closed field is an extension of a definably compact fsg definable group by a dfg definable group. We discuss an approach which might prove a similar (...) statement for interpretable abelian groups. In the case where G is an abelian group definable in the standard model $\mathbb {Q}_p$, we show that $G^0 = G^{00}$, and that G is an open subgroup of an algebraic group, up to finite factors. This latter result can be seen as a rough classification of abelian definable groups in $\mathbb {Q}_p$. (shrink)

Public health policies designed to improve individual and population health may involve coercion. These coercive policies require ethical justification, and yet it is unclear in the public health ethics literature which ethical concepts might justify coercion, and what their limitations are in applying across contexts. In this paper, we analyse a number of concepts from Western bioethics, including the harm principle, paternalism, the public interest, and a duty of easy rescue. We find them plausible justifications for coercion in theory, but (...) when applied to case studies, including HIV testing in Malawi, vaccine mandates in South Africa, and prohibitions of antibiotic use in livestock in the EU, their limitations become clear. We argue that the context-specificity of ethical justifications for coercion has been overlooked, and there is more work needed to identify context-relevant ethical justifications for coercive policies in various settings and for various populations, rather than relying on universalising Western bioethical justifications across all contexts.

Overestimation of one’s ability to argue their position on socio-political issues may partially underlie the current climate of political extremism in the U.S. Yet very little is known about what factors influence overestimation in argumentation of socio-political issues. Across three experiments, emotional investment substantially increased participants’ overestimation. Potential confounding factors like topic complexity and familiarity were ruled out as alternative explanations. Belief-based cues were established as a mechanism underlying the relationship between emotional investment and overestimation in a measurement-of-mediation and manipulation-of-mediator (...) design. Representing a new bias blind spot, participants believed emotional investment helps them argue better than it helps others ; where in reality emotional investment harmed or had no effect on argument quality. These studies highlight misguided beliefs about emotional investment as a factor underlying metacognitive miscalibration in the context of socio-political issues. (shrink)

In this paper, a novel efficient algorithm is presented for locating and tracking object parts in low resolution videos using Lowe's SIFT keypoints with a nearest neighbor object detection approach. Our interest lies in using this information as one step in the process of automatically programming service, household, or personal robots to perform the skills that are being taught in easily obtainable instructional videos. In the reported experiments, the system looked for 14 parts of inanimate and animate objects in 40 (...) natural outdoor scenes. The scenes were frames from a low-resolution instructional video on cleaning golf clubs containing 2,405 frames of 180 by 240 pixels. The system was trained using 39 frames that were half-way between the test frames. Despite the low resolution quality of the instructional video and occluded training samples, the system achieved a recall of 49% with a precision of 71% and an F1 of 0.58, which is better than that achieved by less demanding applications. In order to verify that the reported results were not dependent on the specific video, the proposed technique was applied to another video and the results are reported. (shrink)

We demonstrate that Statistical significance (Chow 1996) includes straw man arguments against (1) effect size, (2) meta-analysis, and (3) Bayesianism. We agree with the author that in experimental designs, H0 “is the effect of chance influences on the data-collection procedure . . . it says nothing about the substantive hypothesis or its logical complement” (Chow 1996, p. 41).

BackgroundRobust ethics consultation services cannot be sustained by all hospitals; consultative service from a high-volume center via teleconferencing is an attractive alternative. This pilot study was conceived to explore the feasibility and understand the practical implications of offering such a service.MethodsHigh-definition videoconferencing was used to provide real-time interaction between the rounding clinicians and a remote clinical ethicist. Data collection included: (1) evaluation of the hardware and software required for teleconferencing, and (2) comparison of ethics trigger counts between the remote and (...) on-site ethicist during rounds.ResultsIssues with audio represented the majority of technical problems. Once technical difficulties were addressed, the onsite ethicist’s count of “triggers” was not statistically different from the count of the remote ethicist.ConclusionRemote clinical ethics rounding is feasible when the equipment is optimized. Remote ethicists can identify similar numbers of “triggers” for possible ethical issues when compared to on-site ethicist numbers. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:166 BOOK REVIEWS Those who read this handsome book and study the paintings and sculptures of Zarlenga in excellent color will be able to follow the phases of his artistic development and find many subjects for medita· tion and enjoyment. Aquinas Institute of Theology St. Louis, Missouri BENEDICT M. ASHLEY, O.P. The Thought of Thomas Aquinas. By BRIAN DAVIES, O.P. Oxford: Oxford University Press, 1992 (cloth); Oxford: Clarendon Press, (...) 1993 (paper). Pp. xv + 391. An establishing circumstance of the ' restoration ' of Christian philosophy at the end of the last century, and the turn of this century, was that the medieval authors whom Christian philosophers turned to were, by profession, theologians whose appropriation of philosophy was for explicitly theological ends. By and large, however, the modern authors who set about retrieving medieval thought had an agenda quite different from that of their medieval luminaries. Still reeling from the philosophical fall-out of the Enlightenment, and encountering rationalism, idealism, and empiricism on all sides, committed Christian thinkers sought a source of philosophical reflection and, perhaps more importantly, justification, that could buttress the claims made by Christianity for those who were within the believing community, and defend the faith from the intellectual attacks of those who were not. The enduring philosophical inheritance of the Middle Ages, and particularly the philosophia perennis of St. Thomas Aquinas, was that source, wrote Leo XIII in his Aeterni patris, and Catholic philosophers soon collected. But the inheritance was not fully collected. With distinctive philosophical goals in mind, Christian philosophers focused upon the putative philosophy of medieval writers, particularly Aquinas, and largely left theological reflection alone. And, when theological contentions on the part of medieval authors did make their way into the discussion, they were almost inevitably appropriated as a legitimate incorporation of revealed teaching into what somehow remained the philosophical project. The result was 'Christian Philosophy.' Although this resulted in the flurry of Catholic philosophical study during the first half of this century, the picture that emerged of the medieval authors, and of Thomas in particular, was inevitably one-sided, and incomplete. An overly pessimistic assessment of the situation would be to say that, for all the hard work of the Gilsons and Maritains, Van Steenberghens and DeKonincks, we are no nearer to Thomas today than we were in the 1870s. BOOK REVIEWS 167 Brian Davies's endeavor seeks to change that, because it attempts to provide the modern reader with a comprehensive introduction to the great expanse of Thomas's thought according to the manner in which Thomas himself presented it in his mature theological masterpiece, the Summa theologiae. Fr. Davies has succeeded magnificently, and his book will become, as it should, a mainstay on the bookshelves of university libraries, students, and teachers alike. Professional philosophers whose work never leads them to Thomas's discussion on Christ, say, can readily get a good working knowledge of how Thomas approaches this center of Christian faith and practice. And the student who is altogether new to Aquinas can grasp something of the ' movement ' of Thomas's thought by reading, and re-reading, Davies judicious renderings of Thomas's doctrine on human acts. This is a book of many uses, all of them instructive and helpful. Considering this book to be an introduction, as Fr. Davies does (p. viii), does not do justice to the quantity of his achievement in writing it, or of the student's investment in reading it. The work occupies some 391 pages, reading made difficult by the tightly-knit character of Thomas's thought, though Davies' easy writing helps to allay the burden. The physical constitution of the book, in slightly off-white octavo paper and an 11-point base font, makes for comfortable reading. Davies has avoided excessive footnoting, giving references to Thomas's text judiciously, and he also provides a well-tailored and impressively diverse bibliography at the end.of the volume which can be effectively consulted by his reader. The author himself is a foundational theologian at Blackfriars in Oxford, so one might expect him instinctively to address the particular audience he encounters in his work. But, save on a very few occasions, Fr. Davies is mindful that in... (shrink)

The contributors to The Moral of the Story, all preeminent political theorists, are unified by their concern with the instructive power of great literature. This thought-provoking combination of essays explores the polyvalent moral and political impact of classic world literatures on public ethics through the study of some of its major figures-including Shakespeare, Dante, Cervantes, Jane Austen, Henry James, Joseph Conrad, Robert Penn Warren, and Dostoevsky. Positing the uniqueness of literature's ability to promote dialogue on salient moral and intellectual virtues, (...) editor Henry T. Edmonson III has culled together a wide-ranging exploration of such fundamental concerns as the abuse of authority, the nature of good leadership, the significance of "middle class virtues" and the needs of adolescents. This collection reinvigorates the study of classic literature as an endeavor that is not only personally intellectually satisfying, but also an inimitable and unique way to enrich public discourse.

We give an example of a dense o-minimal structure in which there is a definable quotient that cannot be eliminated, even after naming parameters. Equivalently, there is an interpretable set which cannot be put in parametrically definable bijection with any definable set. This gives a negative answer to a question of Eleftheriou, Peterzil, and Ramakrishnan. Additionally, we show that interpretable sets in dense o-minimal structures admit definable topologies which are “tame” in several ways: (a) they are Hausdorff, (b) every point (...) has a neighborhood which is definably homeomorphic to a definable set, (c) definable functions are piecewise continuous, (d) definable subsets have finitely many definably connected components, and (e) the frontier of a definable subset has lower dimension than the subset itself.

This paper responds to Philipona & O’Regan (2006), which attempts to account for certain color phenomena by appeal to singularities in the space of “accessible information” in the light striking the retina. Three points are discussed. First, it is unclear what the empirical significance/import is of the mathematical analysis of the data regarding the accessible information in the light. Second, the singularity index employed in the study is both mathematically and empirically faulty. Third, the connection drawn between their findings and (...) some data from the World Color Survey is lacking in quantitative analysis in places where it is needed. The difficulties raised prevent Philipona & O’Regan’s conclusions from being accepted. (shrink)

In [16], Peterzil and Steinhorn proved that if a group G definable in an o-minimal structure is not definably compact, then G contains a definable torsion-free subgroup of dimension 1. We prove here a p-adic analogue of the Peterzil–Steinhorn theorem, in the special case of abelian groups. Let G be an abelian group definable in a p-adically closed field M. If G is not definably compact then there is a definable subgroup H of dimension 1 which is not definably compact. (...) In a future paper we will generalize this to non-abelian G. (shrink)

Las ideas filosóficas del ámbito de la actividad física suelen estar sustentadas en concepciones que trascienden la propia disciplina de estudio aludida, de modo que es importante estudiarlas en profundidad. Este ensayo tiene por objetivo comprender la interpretación de los términos movimiento humano y motricidad humana desde la mirada de tres corrientes filosóficas que han sido utilizadas por referentes de la actividad física, el deporte y la Educación Física. La primera corriente filosófica analizada es la de corte idealista, que entiende (...) el movimiento humano como un acto esencialmente mecánico y biológico. La segunda perspectiva filosófica es la materialista, que entiende el movimiento humano como una manifestación de la motricidad, la cual sería inmanente a la esencia del ser humano. Es decir, estaría dotada de intencionalidad. La tercera corriente sería una mirada ecléctica de las dos anteriores, asemejando el concepto de movimiento humano con el de las contemporáneas interpretaciones de motricidad. En otras palabras, el movimiento humano sería parte de la potencia y el acto. Se concluye que, según diferentes perspectivas filosóficas, es posible utilizar el concepto de movimiento y/o motricidad para trascender la mirada idealista o moderna del movimiento humano. (shrink)

Comments on: “Just War Theory in Comparative Perspective: AReview Essay” by Simeon O. Ilesanmi Journal of Religious Ethics 28.1 (Spring 2000).

Background: Managing HIV treatment is a complex multi-dimensional task because of a combination of factors such as stigma and discrimination of some populations who frequently get infected with HIV. In addition, patient-provider encounters have become increasingly multicultural, making effective communication and provision of ethically sound care a challenge. Purpose: This article explores ethical issues that health service providers in the United States and Botswana encountered in their interaction with patients in HIV care. Research design: A descriptive qualitative design was used (...) to collect data from health service providers and patients using focused group discussions. This article is based on responses from health service providers only. Participants and context: This article is based on 11 focused group discussions with a total sample of 71 service providers in seven US sites and one Botswana site. Ethical considerations: Ethical review boards at all the study sites reviewed the study protocol and approved it. Ethical review boards of the study’s coordinating centers, Rutgers University and the University of California at San Francisco, also approved it. The study participants provided a written informed consent to participate. Findings: HIV service providers encountered ethical challenges in all the four Beauchamp and Childress’ biomedical ethics of respect for patients’ autonomy, beneficence, justice, and nonmaleficence. Discussion: The finding that HIV service providers encounter ethical challenges in their interaction with patients is supported by prior studies. The ethical challenges are particularly prominent in multicultural care and resource-constrained care environments. Conclusion: Provision of HIV care is fraught with ethical challenges that tend to pose different issues depending on a given care environment. It is important that strong partnerships are developed among key stakeholders in HIV care. In addition, health service providers need to be provided with resources so they can provide quality and ethically sound care. (shrink)

This volume is the first scholarly edition of Samuel Johnson’s translation of Jean Pierre de Crousaz’s _Commentaire sur la traduction en vers de M. Abbé Du Resnel, de l’Essai de M. Pope sur l’homme, _published in 1739. Included are notes comparing Johnson’s translation with the French original to show his method of translation and historical annotations. Of special interest are several lengthy footnotes that Johnson added to his translation. Among these are thoughts relating to the problem of (...) evil, particularly the ruling passion and the necessity of free will. Many of the ideas first given expression here were to occupy Johnson’s mind for the remainder of his life. (shrink)

Much recent work on Kant's argument that the Categorical Imperative is the fundamental principle of morality has focused on the gap in that argument between the conclusion that rational agents conform to laws that apply to every rational agent, and the requirement contained in the Universal Law of Nature formula.1 While it seems plausible – even trivial– that a rational agent, insofar as she is a rational agent, conforms to whatever laws there are that are valid for all rational agents, (...) there does not appear to be any obvious route from this seemingly trivial claim to the controversial and substantive principle of acting only on maxims that one can at the same time rationally will every rational agent to act on.2 In what follows, I argue that the connection between rational agency and mere conformity to universally valid laws is not as trivial as it may seem. Many readers, I suspect, assume that Kant makes the trivial claim about rational agency because rational agency is rational, and being rational requires conforming to those laws that apply to all rational beings. For instance, this assumption is implicit in Onora O'Neill claim that "the interest of a Kantian universality test is that it aims to ground an ethical theory on notions of consistency and rationality rather than upon considerations of desire and preference."3 But, as I contend in what follows, the requirement to conform to laws valid for all rational agents is based on the fact that rational agency is, not rational, but agency. Indeed, the arguments leading to the first formulation of the Categorical Imperative rely on the idea of rational willing as a kind of causation in order to show this. And, as it turns out, the claim that the concept of causation contains the idea of conformity to universally valid laws is not a trivial claim. (shrink)

James Turner Johnson is the foremost scholar of the just war tradition working today. His treatment of the historical development of the just war tradition has been hugely important, influencing a generation of theorists. Despite this, Johnson's work has not generated much in the way of critical commentary or analysis. This paper aims to rectify this oversight. Engaging in a close and critical reading of Johnson's work, it claims that his historical reconstruction of the just war tradition (...) is bounded by two key thematic lines — the imperative of vindicative justice and the ideal of Christian love — and occasionally betrays an excessive deference to the authority of past practice. By way of conclusion, this paper sums up the promise and limits of Johnson's approach, and reflects upon its contribution to contemporary just war scholarship. (shrink)

Disturbances of consciousness, including fluctuations in attention and awareness, are a common and clinically important symptom in dementia with Lewy bodies. In the present study we investigate potential mechanisms of such disturbances of consciousness in a clinicopathological study evaluating specific components of the cholinergic system. [3H]Epibatidine binding to the high-affinity nicotinic receptor in the temporal cortex differentiated DLB cases with and without DOC, being 62–66% higher in those with DOC. The were no differences between DLB patients with or without DOC (...) in 125I-labeled α-bungaratoxin binding to the low-affinity nicotinic receptor, [3H]pirenzepine binding to the muscarinic M1 receptor, or in choline acetyltransferase activity. These findings provide support for the hypothesis that cholinergic activity is an important neural correlate if consciousness and suggest a mechanism of DOC in DLB involving alterations in the nicotinic receptor, composed of predominantly α4 and β2 subunits.
