ObjectiveTo compare techniques for computing clustering and switching scores in terms of agreement, correlation, and empirical value as predictors of incident cognitive impairment.MethodsWe transcribed animal and letter F fluency recordings on 640 cases of ICI and matched controls from a national epidemiological study, amending each transcription with word timings. We then calculated clustering and switching scores, as well as scores indexing speed of responses, using techniques described in the literature. We evaluated agreement among the techniques with Cohen’s κ and calculated (...) correlations among the scores. After fitting a base model with raw scores, repetitions, and intrusions, we fit a series of Bayesian logistic regression models adding either clustering and switching scores or speed scores, comparing the models in terms of several metrics. We partitioned the ICI cases into acute and progressive cases and repeated the regression analysis for each group.ResultsFor animal fluency, we found that models with speed scores derived using the slope difference algorithm achieved the best values of the Watanabe–Akaike Information Criterion, but with good net reclassification improvement only for the progressive group. For letter fluency, different models excelled for prediction of acute and progressive cases. For acute cases, NRI was best for speed scores derived from a network model, while for progressive cases, the best model used clustering and switching scores derived from the same network model. Combining variables from the best animal and letter F models led to marginal improvements in model fit and NRI only for the all-cases and acute-cases analyses.ConclusionSpeed scores improve a base model for predicting progressive cognitive impairment from animal fluency. Letter fluency scores may provide complementary information. (shrink)

This collection, the first of its kind, brings together specially commissioned academic essays to mark fifty years since the death of John Kennedy Toole.

Debriefing is a standard ethical requirement for human research involving the use of deception. Little systematic attention, however, has been devoted to explaining the ethical significance of debriefing and the specific ethical functions that it serves. In this article, we develop an account of debriefing as a tool of moral accountability for the prima facie wrong of deception. Specifically, we contend that debriefing should include a responsibility to promote transparency by explaining the deception and its rationale, to provide an apology (...) to subjects for infringing the principle of respect for persons, and to offer subjects an opportunity to withdraw their data. We also present recommendations concerning the discussion of deception in scientific articles reporting the results of research using deception. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A THEORY OF BASIC GOODS: STRUCTURE AND HIERARCHY* I. FTEN, PERHAPS ALWAYS, moral theory emerges from particular problems. Just how is obscure. The logic of discovery is elusive; and it is harder to explain how we have come to see matters rightly than to recognize that we do, in fact, see them rightly. What counts as a theory, moreover, calls for explication as much as does a theory's emergence. (...) When we have in mind a theory that shapes our social vision, there is a progression from a central set of propositions, keyed to a range of paradigm cases and seen as a logical structure, to a " way of thinking " widely enough embraced to have political significance, at least for a given oommunity. In this essay I want to explore some fundamental questions raised by Germain Grisez's theory of natural law ethics.1 These questions are chiefly conceptual. But neither they nor Grisez's theory should be seen in a vacuum. Rather, I would begin by suggesting that the importance of his work, its emergence in some Catholic circles, is linked with two specific moral and political problems. The first is abortion; the second is the superpowers' policy of nuclear deterrence. *I thank David Blake, Robert Gordh, Carroll Kearley, Gary Mar. Martin Woods, and Linda Zagzebski for their comments on an earlier version of this essay. 1 For the theory's fullest presentation, see Germain Grisez, The Way of the Lord Jesus, vol. one, Ohristian Moral Principles, with the help of Joseph M. Boyle, Jr., Basil Cole, O.P., John Finnis, John A. Geinzer, Robert G. Kennedy, Patrick Lee, William E. May, and Russell Shaw (Chicago: Franciscan Herald Press, 1983). Especially critical are chapters two through twelve. 221 JAMES G. HANINK As a point of chronology, Grisez's early study of rubortion was the context for one of the first formulations of his natural law ethics.2 But why should this have been so? And why should abortion so engage Catholic thinkers, some of whom had felt a distance from explicitly Catholic positions, that Grisez's work should become pivotal? Answers to such questions must be tentative, but they include the following considerations. In a brief period, no more than a decade, legal abortion in the West became entrenched social policy.8 It was a policy, too, supported by dominant intellectual forces. But the new policy, defended in terms of individual freedom and a right to privacy, struck many Catholicsand non-Catholics-as vicious and tragic. It was vicious in that it made expendable the weakest and most vulnerable human beings. Human rights somehow became restricted to the strong and self-sufficient. The policy was tragic in its denial of human community. We are not, however much radical individualism supposes, merely a collection of separate egos. l/Ve are, rather, a community tied to a past and pledged to a future, so pledged, in part, by the children we bear and nurture.4 For in hearing and nurturing children we carry on the love of parents who have done as much for us; and we carry ourselves into a future where we hope our own love will be thus extended. But abortion, and surely unrestricted abortion, betrays this community of trust. Still, a policy so vicious and tragic can make us look for a fresh moral vision. And, of course, to the extent that we have contributed to,a climate in which abortion could become entrenched -either by our failures to support women in need or 2 Germain Grisez, Abortion: The Myths, the Realities, and the Arguments (New York and Cleveland: Corpus Books, 1970). a A milepost, of course, was the United States Supreme Court decision, Roe v. Wade, in 1973. Recent U.S. Government figures indicate that there are now well over a million legal abortions annually in this country. 4 For a provocative discussion of this theme, see Stanley Hauerwas's " The Moral Value of the Family " in his A Commimity of Character (Notre Dame: University of Notre Dame Press, 1981).

Moral enhancement is an ostensibly laudable project. Who wouldn’t want people to become more moral? Still, the project’s approach is crucial. We can distinguish between two approaches for moral enhancement: direct and indirect. Direct moral enhancements aim at bringing about particular ideas, motives or behaviors. Indirect moral enhancements, by contrast, aim at making people more reliably produce the morally correct ideas, motives or behaviors without committing to the content of those ideas, motives and/or actions. I will argue, on Millian grounds, (...) that the value of disagreement puts serious pressure on proposals for relatively widespread direct moral enhancement. A more acceptable path would be to focus instead on indirect moral enhancements while staying neutral, for the most part, on a wide range of substantive moral claims. I will outline what such indirect moral enhancement might look like, and why we should expect it to lead to general moral improvement. (shrink)

Human life and death should be defined biologically. It is important not to conflate the definition of death with the criteria for when it has occurred. What is distinctively "human" from a scientific or normative perspective has nothing to do with what makes humans alive or dead. We are biological organisms, despite the fact that what is meaningful about human life is not defined in biological terms. Consequently, as in the rest of the realm of living beings, human beings die (...) when they no longer function biologically as organisms. In contrast, a determination of exactly when death has occurred, required to serve various social purposes, combines social and normative considerations with biological facts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:FDA Releases Draft Guidance on Regulation of Genetically Engineered AnimalsJohn P. Gluck (bio) and Mark T. Holdsworth (bio)On 18 September 2008, the U.S. Food and Drug Administration (FDA) issued a draft set of guidelines for those involved in developing genetically engineered animals with heritable recombinant DNA (rDNA) constructs and is requesting comment from industry and the public about their content. The document does not impose new regulations but details (...) how existing laws and regulations apply to genetically engineered (GE) animals and offers advice to developers on how to negotiate the laws in the most efficient and productive manner. The draft guidance document is not legally enforceable at this juncture, but the guidelines are recommendations reflecting the FDA's "current thinking on a topic."The modification of GE animals being developed for commercialization, which are the focus of the document, fall into six categories: modifications intended to (1) enhance food quality—e.g., faster growing fish and meats with better nutritional profiles; (2) improve animal health via increased resistance to disease—e.g., mastitis in dairy cattle and Bovine Spongiform Encephalopathy (BSE); (3) create so-called "biopharm" animals capable of producing therapeutic products such as insulin, clotting factors, and tissues for human transplantation; (4) reduce the barriers to human animal interaction—e.g., hypoallergenic pets; (5) develop valid animal models of human disease—e.g., Parkinson's disease, Lesh-Nyhan's syndrome, and cancer; and (6) improve production of industrial or consumer products such as fiber. The timing of the guidelines coincides with the FDA's belief in an expected boon in the number of GE animals approaching the stage of commercialization.The FDA's involvement in the approval process emerges from the new animal drug provisions of the Federal Food Drug and Cosmetic Act and the definition of what constitutes a drug. The Act defines a new animal drug as "an article (other than food) intended to affect the structure or any function of the body of... animals." A rDNA construct intended to affect the structure or function of an animal meets the definition of a new animal drug, regardless of whether the resulting GE animals are intended for human food or the production of pharmaceuticals or any other substances. [End Page 393]Before proceeding to a review of the draft guidelines, it is important briefly to set the controversies around GE animals in historical and ethical context.The Ethical DebateFrom its inception, the intentional genetic modification or genetic engineering of molecules, plants, and animals by the techniques of gene splicing has consistently elicited strong responses from both the scientific community and the public. There are some data to suggest that although the concerns of scientists fall primarily into the category of possible biohazards, those of the public also reflect great concern about the intrinsic moral issues, such as whether there is something fundamentally wrong with this line of work, making it a form of forbidden knowledge (see, e.g., Gaskell 1997). When news of Paul Berg's attempts in 1970 to graft the primate tumor virus (SV 40) onto the intestinal tract bacteria Escherichia coli for the purpose of studying how normal cells may be transformed into cancerous cells was shared with colleagues, he was strongly encouraged to reflect on the potential public health risks if somehow the altered bacteria broke containment and entered the environment. Thanks to Berg's leadership, these concerns soon resulted in conferences held in Asilomar, California, and New Hampton, New Hampshire, where the ethical responsibilities of microbiologists involved in this research were discussed. These initial discussions resulted in what has come to be known as "The Moratorium Letter" (Shattuck 1996) published in the journal Science in 1974. This letter, signed by 11 leaders in the field, actually recommended restrictions on several types of experiments that were considered to be particularly risky and stated "that adherence to our major recommendations will entail postponement or possibly abandonment of certain types of scientifically worthwhile experiments" (Berg 1974). An international conference on the issues came to similar conclusions about the need for a research moratorium for the sake of public safety. Recommendations arising from conference participants led to the formation of the National Institutes... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aquinas on the Beginning and End of Human Life by Fabrizio AmeriniJohn LanganReview: Fabrizio Amerini, Aquinas on the Beginning and End of Human Life, trans. Mark Henninger, Harvard University Press, 2013The ongoing and apparently interminable debate over the moral and legal status of abortion has come over the years to resemble the Western front in World War I, with two contending armies facing each other with limited maneuvering (...) room, familiar and overused weapons, periodic artillery barrages, increasing casualties, not much new to report, and a deadly ‘no man’s land’ between them in which virtually nothing survives. Against the gloomy monotony of the abortion wars, in which reductivist accounts of the opponents’ views and repetitious restatements of familiar and cherished views predominate, this book by Fabrizio Amerini, a professor of philosophy at the University of Parma, appears as a refreshing surprise. It is surprising for a number of reasons, which I shall present later. But its refreshing character comes primarily from its moderate tone and the care with which its arguments are presented. Amerini is clearly familiar with the Catholic tradition on abortion and euthanasia; he is respectful of this tradition, which he does not directly challenge, but his sense of scholarly integrity prevents him from simply presenting Aquinas as a defender and synthesizer of all the positions championed in that tradition or by its papal custodians. He has an impressive command of the relevant texts in Aquinas and the Fathers of the Church, which he joins with a scrupulous style of [End Page E-103] philosophical argument which has an affinity with the clarifying labors of G. E. Moore in the early days of analytic moral philosophy. The result is not easy reading, but the reader can be confident that the desire to score rhetorical points and political victories will not distort the philosophical and historical analysis. The book is intended primarily for those who can benefit from careful scholarship, but it should be instructive for all who regard the questions of abortion and euthanasia as genuinely difficult and as deserving our best intellectual efforts.The most important surprise is Amerini’s focus on the issue of delayed versus immediate hominization in the development from embryo to complete human being. Since Pius IX in 1867, the Vatican has insisted that from the moment of conception the embryo becomes a human person whose life is sacred and deserves full protection. This view is ordinarily discussed as ‘immediate hominization’. In Amerini’s view, the embryo lacks the development and differentiation of organs which would enable it to have a sustainable potentiality to perform the acts which are proper to a human person, particularly reasoning and choosing. In the Vatican’s view, the soul is immediately infused by God, though it obviously requires many years of development before it is able to function as a complete and distinct human person. Amerini regards this position as untenable within Aquinas’s metaphysical system and finds in Aquinas’s own texts evidence that he teaches a discontinuous process in fetal life. Amerini regards the insistence on immediate hominization as an arbitrary effort to maintain an absolute uniformity of moral status in all the stages of embryonic and fetal life. He sees the Vatican’s position as leading to an equation of abortion and homicide which he regards as unjustified. He does, however, affirm that there is an identity of subject running from the embryo to the developed person and also that this grounds an ethic of respect for life in all of its stages. The practical conclusions in bioethics he would draw from this position “could allow space for a judicious and discriminating ethical evaluation of individual cases,” as he puts the matter in the concluding sentence of the book.Other surprises are the author’s discovering from a careful reading of Aquinas’s texts that he taught a progressive plurality of substantial forms in the development of the embryo. For Aquinas, it is the substantial form which answers the question about what sort of being the object of our inquiry is. In the case of human persons, the substantial form is the soul, which includes the intellectual properties of... (shrink)

The article elucidates and defends whitehead's claim that john locke anticipated the main positions of the philosophy of organism. It is argued that the major philosophical categories of locke's epistemology and whitehead's process philosophy perform similar functions. The functional parallels between the mind and the actual entity, Simple ideas and objectified actual entities, Mental operations and concrescence, Ideas and objects, And power and the ontological principle are delineated and examined. The conclusion extends a necessary caveat in assessing the philosophy (...) of organism via locke's epistemology. (shrink)

Edible insects are a potentially less burdensome source of proteins on the environment than livestock for a majority of rural consumers. Hence, edible insects are a timely idea to address the challenges of the supply side to sustainably meet an increasing demand for food. The objective of this paper is twofold. The first is to identify and compare rural-households’ intentions to consume insect-based foods among households drawn from two regions in Kenya—one where consumption of insects is common and the other (...) where the practice is uncommon. The second is to explore consumers’ trust in sources of information regarding quality and appropriateness of food items. The study employed an extended theory of planned behaviour and involved 432 participants. Results indicate that rural households have positive intentions to consume insect-based foods and those intentions are higher for individuals who are more familiar with the practice. Results also show that information sources from industry are more trusted than those from the media. Further, the study revealed that control variables such as perceived availability of insect-based foods and their level of fit with the culinary practices have a higher influence on consumption intentions than general attitudes. In addition, age of the respondent, gender, household size and level of formal education, significantly influence the consumption intentions. The study discusses the implications of these findings in the development of sustainable agri-food systems. (shrink)

Mark Johnson argues in favour of embodied experience as the basis for knowledge. An important implication of his analysis is that these experiences instigate pervasive metaphorical systems. Johnson 's argument involves reductionist problems, chicken-and-egg problems and, at times, unclear criteria for what counts as a basic experience and a metaphor.

In lieu of an abstract, here is a brief excerpt of the content:“Unduly Iterative Ethical Review?”Franklin G. MillerMadam:Renée C. Fox and Nicholas A. Christakis have written a provocative article, “Perish and Publish: Non-Heart-Beating Organ Donation and Unduly Iterative Ethical Review” (KIEJ, December 1995). The language of their argument and some of the implicit assumptions on which it rests deserve critical scrutiny. They describe the articles presenting and commenting on the University of Pittsburgh protocol as “disquieting” because the display “trial-and-error ethics.” (...) To dismiss “trial-and-error ethics” implies that we antecedently possess all the moral knowledge we need to evaluate and regulate developments in medicine. Should we summarily reject experimentation in ethics, particularly with respect to complex issues involving scientific and technological changes? For if we need to reconsider and possibly revise what counts as moral knowledge, the proposing an experimental approach to the ethics of a novel practice, which is presented publicly and made open to revision, as in the Pittsburgh protocol, may be precisely the best way to proceed.Fox and Christakis resort to invidious insinuation in their criticism of ethicists who have written, and journals that have published, articles about non-heart-beating organ donation. Publication on this issue has given ethicists the opportunity of “adding numerous items to their vitae.” Their appraisal of the vitae-boosting behavior represents an interesting rhetorical specimen: “Although there is nothing inherently dishonorable about this it does create tension between two motives: conviction about the importance of perfecting ethical conduct, on the one hand, and the desire to advance one’s professional career, on the other” (p. 340). I am not sure what the authors mean by “perfecting ethical conduct.” Yet they suggest that a group of reputable scholars, who have taken diverse positions on the ethics of non-heart-beating organ donation, have come perilously close to venality.Finally, in order to avoid further legitimating what they consider to be an ethically objectionable practice, the authors advocate that journals exercise “restraint” in publishing articles about this topic. Perhaps in a future pronouncement they will enlighten us about how enforcing a publication policy that avoids the vice of “unduly iterative ethical review” might work without compromising freedom of discussion.

In the end, even the creative achievements of Shakespeare and Bach must be eradicated by death and nothingness, when the earth is burnt up in the sun. But the temporality of human existence and meaning does not invalidate the quest for meaning-for even that future universe, as dead as it must be will have some meaning, in that it contains the artifacts, even in ashes, of the sometime existence of human life and consciousness.

Kennedy shows that Plato gave his dialogues a similar musical structure, dividing each dialogue into twelve parts and inserting symbols at each twelfth to mark a musical note. These passages are either harmonious or dissonant and traverse the ups and downs of a known musical scale. Many of Plato's early followers insisted that Plato used symbols to conceal his own views within the dialogues, but modern scholars have denied this. Kennedy, an expert in Pythagorean mathematics and music theory, (...) is able to show that Plato's dialogues contain a system of symbols that are undetectable by those without knowledge of obsolete Greek mathematics. The book begins with a concise and accessible introduction to Plato's symbolic schemes and the role of allegory in ancient times. The author then annotates the musical symbols in two of Plato's most popular dialogues, the Symposium and Euthyphro, and shows that Plato used the musical scale as an outline for structuring his narratives.

In a case-history, Ben, a university-graduate blind adult, is shown to draw a cube as if it were folded out, but with slim rectangles for the sides around a central square. This form is drawn by sighted 8-year-olds. It might involve foreshortening and parallel projection, despite the presence of more sides than would be present in parallel projection in a single direction. Also, Ben drew a glass’s brim as both a straight line and as an ellipse, a form common in (...) drawings by sighted 8-year-olds that may include the circular brim foreshortened to an ellipse in a ¾ view. In several drawings made later in the testing session Ben only showed aspects of the depicted object facing one direction. In elevation and plan drawings, he showed aspects facing to the side of the object or above the object. Also, Ben’s use of foreshortening advanced in sophistication in the testing session. We hypothesize that the blind and the sighted are on the same drawing developmental trajectory. (shrink)

In his famous 1982 paper, Allen Newell [22, 23] introduced the notion of knowledge level to indicate a level of analysis, and prediction, of the rational behavior of a cognitive arti cial agent. This analysis concerns the investigation about the availability of the agent knowledge, in order to pursue its own goals, and is based on the so-called Rationality Principle (an assumption according to which "an agent will use the knowledge it has of its environment to achieve its goals" [22, (...) p. 17]. By using the Newell's own words: "To treat a system at the knowledge level is to treat it as having some knowledge, some goals, and believing it will do whatever is within its power to attain its goals, in so far as its knowledge indicates" [22, p. 13]. In the last decades, the importance of the knowledge level has been historically and system- atically downsized by the research area in cognitive architectures (CAs), whose interests have been mainly focused on the analysis and the development of mechanisms and the processes governing human and (arti cial) cognition. The knowledge level in CAs, however, represents a crucial level of analysis for the development of such arti cial general systems and therefore deserves greater research attention [17]. In the following, we will discuss areas of broad agree- ment and outline the main problematic aspects that should be faced within a Common Model of Cognition [12]. Such aspects, departing from an analysis at the knowledge level, also clearly impact both lower (e.g. representational) and higher (e.g. social) levels. (shrink)

It is difficult to find just one place to look for children and childhood in the American philosopher John Dewey’s work. This is not because he uses the terms so often, but because the concept of childhood pervades his opus in and through another set of terms—development, growth, experience, plasticity, habit, impulse, and education. In Dewey’s language, none of these terms mean quite what they mean in other thinkers’ language, and especially not in the language of the human development (...) theorists of the early twentieth century and after, who based their thinking on a monological, unidirectional developmental trajectory that could be applied at all levels of the evolutionary continuum. Dewey is an interactionist through and through, and thus all his terms should be understood as dialectical. He does not invoke the concept “child” without invoking the concept “adult,” nor does he describe anything that does not have a normative dimension, which by definition belies “pure” description. His is a language of possibility, and the limits of human possibility are incalculable. This is why the concept of childhood is so important in his work. In this text we present selections from two works, the first emerging at the sickening epicenter of the Great War, in 1916—a war in which youth was sacrificed to what he calls adult “infantilisms” on a historically unprecedented scale, and a war that, arguably, effectively suppressed the educational possibilities his work represents for the rest of the century. Democracy and Education is his magnum opus on education, and characteristically both garrulous and brilliantly pointed, maddeningly oblique and trenchantly critical, painfully dull and fitfully enthralling, explicitly conservative and implicitly radical. The next selections are from Human Nature and Conduct , published in 1922, when the orgiastic death-feast of the tyrants, the politicians, and their hosts of blind acolytes was over. (shrink)
