We present a formalization of first-order predicate calculus with equality which, unlike traditional systems with axiom schemata or substitution rules, is finitely axiomatized in the sense that each step in a formal proof admits only finitely many choices. This formalization is primarily based on the inference rule of condensed detachment of Meredith. The usual primitive notions of free variable and proper substitution are absent, making it easy to verify proofs in a machine-oriented application. Completeness results are presented. The example (...) of Zermelo-Fraenkel set theory is shown to be finitely axiomatized under the formalization. The relationship with resolution-based theorem provers is briefly discussed. A closely related axiomatization of traditional predicate calculus is shown to be complete in a strong metamathematical sense. (shrink)

Non-Invasive Prenatal Testing is a technology which provides information about fetal genetic characteristics very early in pregnancy by examining fetal DNA obtained from a sample of maternal blood. NIPT is a morally complex technology that has advanced quickly to market with a strong push from industry developers, leaving many areas of uncertainty still to be resolved, and creating a strong need for health policy that reflects women’s social and ethical values. We approach the need for ethical policy-making by studying the (...) use of NIPT and emerging policy in the province of Ontario, Canada. Using an adapted version of constructivist grounded theory, we conducted interviews with 38 women who have had personal experiences with NIPT. We used an iterative process of data collection and analysis and a staged coding strategy to conduct a descriptive analysis of ethics issues identified implicitly and explicitly by women who have been affected by this technology. The findings of this paper focus on current ethical issues for women seeking NIPT, including place in the prenatal pathway, health care provider counselling about the test, industry influence on the diffusion of NIPT, consequences of availability of test results. Other issues gain relevance in the context of future policy decisions regarding NIPT, including funding of NIPT and principles that may govern the expansion of the scope of NIPT. These findings are not an exhaustive list of all the potential ethical issues related to NIPT, but rather a representation of the issues which concern women who have personal experience with this test. Women who have had personal experience with NIPT have concerns and priorities which sometimes contrast dramatically with the theoretical ethics literature. These findings suggest the importance of engaging patients in ethical deliberation about morally complex technologies, and point to the need for more deliberative patient engagement work in this area.

Abstract:While the medical ethics literature has well explored the harm to patients, families, and the integrity of the profession in failing to disclose medical errors once they occur, less often addressed are the moral and professional obligations to take all available steps to prevent errors and harm in the first instance. As an expanding body of scholarship further elucidates the causes of medical error, including the considerable extent to which medical errors, particularly in diagnostics, may be attributable to cognitive sources, (...) insufficient progress in systematically evaluating and implementing suggested strategies for improving critical thinking skills and medical judgment is of mounting concern. Continued failure to address pervasive thinking errors in medical decisionmaking imperils patient safety and professionalism, as well as beneficence and nonmaleficence, fairness and justice. We maintain that self-reflective and metacognitive refinement of critical thinking should not be construed as optional but rather should be considered an integral part of medical education, a codified tenet of professionalism, and by extension, a moral and professional duty.

There are clear associations between the overall quantity of input children are exposed to and their vocabulary acquisition. However, by uncovering specific features of the input that matter, we can better understand the mechanisms involved in vocabulary learning. We examine whether exposure to wh-questions, a challenging quality of the communicative input, is associated with toddlers' vocabulary and later verbal reasoning skills in a sample of low-income, African-American fathers and their 24-month-old children. Dyads were videotaped in free play sessions at home. (...) Videotapes were transcribed and reliably coded for sheer quantity of fathers' input as well as the number of wh-questions fathers produce. Children's productive vocabulary was measured at 24 months using the McArthur Bates Communicative Development Inventory MCDI, and children's verbal reasoning skills were measured 1 year later using the Bayley Scales of Infant Development. Results indicate that the overall quantity of father talk did not relate to children's vocabulary or reasoning skills. However, fathers' use of wh-questions related to both vocabulary and reasoning outcomes. Children's responses to wh-questions were more frequent and more syntactically complex, measured using the mean length of utterance, than their responses to other questions. Thus, posing wh-questions to 2-year-olds is a challenging type of input, which elicits a verbal response from the child that likely helps build vocabulary and foster verbal reasoning abilities.

Doig, Meredith The promise from new Victorian Premier, Daniel Andrews, to make Victoria the 'education state' is welcome and timely.

This book addresses how Plato, Kant, and Iris Murdoch view the connection aesthetic experience has to morality. While offering an examination of Iris Murdoch’s philosophy, it analyses deeply the suggestive links between Plato’s and Kant’s philosophies. Meredith Trexler Drees considers not only Iris Murdoch’s concept of unselfing, but also its relationship with Kant’s view of Achtung and Plato’s view of Eros. In addition, Trexler Drees suggests an extended, and partially amended, version of Murdoch’s view, arguing that it is more (...) compatible with a religious way of life than Murdoch herself realized. This leads to an expansion of the overall argument to include Kant’s affirmation of religion as an area of life that can be improved through Plato’s and Murdoch’s vision of how being good and being beautiful can be part of the same life-task.

Nineteenth-century optical toys that showcase illusions of motion such as the phenakistoscope, zoetrope, and praxinoscope, have enjoyed active “afterlives” in the twentieth and twenty-first centuries. Contemporary incarnations of the zoetrope are frequently found in the realms of fine art and advertising, and they are often much larger than their nineteenth-century counterparts. This article argues that modern-day optical toys are able to conjure feelings of wonder and spectacle equivalent to their nineteenth-century antecedents because of their adjustment in scale. Exploring a range (...) of contemporary philosophical toys found in arts, entertainment, and advertising contexts, the article discusses various technical adjustments made to successfully “scale up” optical toys, including the replacement of hand-spun mechanisms with larger sources of motion and the use of various means such as architectural features and stroboscopic lights to replace traditional shutter mechanisms such as the zoetrope’s dark slots. Critical consideration of scale as a central feature of these installations reconfigures the relationship between audience and device. Large-scale adaptations of optical toys revise the traditional conception of the user, who is able to tactilely manipulate and interact with the apparatus, instead positing a viewer who has less control over the illusion’s operation and is instead a captive audience surrounded by the animation. It is primarily through their adaptation of scale that contemporary zoetropes successfully elicit wonder as scientific spectacles from their audiences today. (shrink)

_Wittgenstein, Mind and Meaning_ offers a provocative re-reading of Wittgenstein's later writings on language and mind, and explores the tensions between Wittgenstein's ideas and contemporary cognitivist conceptions of the mental. This book addresses both Wittgenstein's later works as well as contemporary issues in philosophy of mind. It provides fresh insight into the later Wittgenstein and raises vital questions about the foundations of cognitivism and its wider implications for psychology and cognitive science.

I discuss Peter Singer’s claim that the interests of animals merit equal consideration with those of human beings. I show that there are morally relevant differences between humans and animals that Singer’s rather narrow utilitarian conception of morality fails to capture. Further, I argue that Singer’s formal conception of moral equality is so thin as to be virtually vacuous and that his attempts to give it moresubstance point to just the kind of differences between humans and animals that undermine his (...) equalitarian thesis.

A classic problem in cognitive science concerns how listeners perceive and understand speech as comprised of discrete words. We propose a Syllable Inference account of spoken word recognition and segmentation, under which alternative hierarchical models of syllables, words, and phonemes are dynamically posited from cues that include current and past speech rate, with a goal of maximal prediction of sensory input. Three experiments using the Visual World eye‐tracking paradigm provide evidence supporting our proposal.

This paper explores the use of chemical symbolism in works by the new media artist Sonya Rapoport, with a focus on the pivotal Cobalt series from the late 1970s. These works, drawings on computer printouts generated by research at the Lawrence Berkeley Laboratory, respond to experiments in nuclear chemistry. They mark the beginning of three productive decades in which Rapoport produced a variety of images related to chemistry in her work. She states, “I looked for authentic research projects that were (...) interesting to me, preferably with captivating pictorial subject matter. Then came the creative chaotic process of resolving a cohesive product that combined scientific research with art concept.” Rapoport had an unusual degree of access to scientific materials through her husband, organic chemist Henry Rapoport, a faculty member at the University of California, Berkeley. At the time of production, these works were outside mainstream art world interests and they have received little critical attention. This paper examines the development of Rapoport’s images and places her use of chemical references in context in her lifetime of work. (shrink)

In this short text, a distinguished philosopher turns his attention to one of the oldest and most fundamental philosophical problems of all: How it is that we are able to sort and classify different things as being of the same natural class? Professor Armstrong carefully sets out six major theories—ancient, modern, and contemporary—and assesses the strengths and weaknesses of each. Recognizing that there are no final victories or defeats in metaphysics, Armstrong nonetheless defends a traditional account of universals as the (...) most satisfactory theory we have.This study is written for advanced students, but as Armstrong goes considerably beyond his earlier work on this topic, it will interest professional scholars as well. Carefully plotted and clearly written, Universals is both a paradigm of exposition and a case study on the value of careful analysis of fundamental issues in philosophy. (shrink)

A review of the literature on corporate governance serves to demonstrate the applicability of many governance solutions to the university setting. Based on a review of university scandals, most of which are recent but some of which took place decades ago, it is possible to categorize them as follows: sex scandals, drugs, cheating, hazing, admissions and diplomas, on-the-job consumption, athletics, and murder. Several examples are provided in the paper, along with their impact on various stakeholders. The paper then discusses a (...) variety of solutions designed to either preempt the activities potentially leading to scandal, to deter them or to punish perpetrators. Some of these involve structural changes, institutional policies and procedures, fines, terminations, and sanctions. The paper emphasizes the proactive safeguards which govern and monitor to make sure that universities do not suffer on the back end and that their reputations do not suffer into the future. (shrink)
