PURPOSE:To report the localization of a gene causing drusen and macular degeneration in a previously undescribed North American family. METHODS:Genetic mapping studies were performed using linkage analysis in a single family with drusen and atrophic macular degeneration. RESULTS:The clinical manifestations in this family ranged from fine macular drusen in asymptomatic middle-aged individuals to atrophic macular lesions in two children and two elderly patients. We mapped the gene to chromosome 6q14 between markers D6S2258 and D6S1644. CONCLUSIONS:In a family with autosomal (...) dominant drusen and atrophic macular degeneration, the gene maps to a 3.2-cM region on chromosome 6q14. This locus appears to be distinct from, but adjacent to, the loci for cone-rod dystrophy 7 (CORD7) and North Carolina macular dystrophy (MCDR1). Future identification of the gene responsible for the disease in this family will provide a better understanding of macular degeneration. (shrink)

As successful as a book of this type could be, with one exception: the selection of recent and contemporary philosophers is all too arbitrary, with its heavy emphasis on British academics reflecting the array of mostly British contributors to the volume. Many fine photographs are included.--J. E. M.

Helpful and thorough as an introduction to Santayana's aesthetic theory, Ashmore's presentation is an exposition of Santayana's views; he does not judge these views or attempt to develop them further. According to Ashmore, Santayana held a single aesthetic theory all his life, the nucleus of which was contained in his early poetry. However, he developed different aspects of this theory at different stages of his life. During the first stage, Santayana emphasizes aesthetic experience. In considering this topic Ashmore discusses aesthetic (...) value, and the psychological analysis that Santayana gives of this value. Next Santayana focuses on poetry and its criticism. Thus Ashmore examines topics such as the relation between poetry and religion, the relation between poetry and philosophy, and Santayana's formulation of a scale for judging poetry. The chapter entitled "Rational Art" presents the third major stage of Santayana's development; here Ashmore considers Santayana's construction of a theory of art. For Santayana, art, as distinct from fine art, is a rational activity in the pursuit of happiness. Ashmore concludes with a discussion of Santayana's final work, considering the additions to and modifications of his earlier views.—E. M. (shrink)

Remarkable for its array of distinguished contributors, the volume begins with a modest autobiography, followed by some twenty-one essays which delve into various aspects of Broad's philosophy. Broad displays a tenacity for the main outlines of his philosophy in his "Reply to My Critics," and concludes by noting that his philosophy is antiquated "without having yet acquired the interest of a collector's piece." This handsome volume is a fine rebuttal.--J. E. M.

In the late 1960s and early 1970s David Marr produced three astonishing papers in which he gave a detailed account of how the fine structure and known cell types of the cerebellum, hippocampus and neocortex perform the functions that they do. Marr went on to become one of the main founders of Computational Neuroscience. In his classic work 'Vision' he distinguished between the computational, algorithmic, and implementational levels, and the three early theories concerned implementation. However, they were produced when (...) Neuroscience was in its infancy.Now that so much more is known, it is timely to revisit these early theories to see to what extent they are still valid and what needs to be altered to produce viable theories that stand up to current evidence. This book brings together some of the most distinguished scientists in their fields to evaluate Marr's legacy. (shrink)

A partire dalla metà del Novecento, dopo una modernità dominata da prospettive di stampo deontologistico o utilitaristico, la filosofia pratica contemporanea ha visto il sorgere di una ripresa di interesse per un’etica “in prima persona”, in grado di offrire una prospettiva integrale sul soggetto e centrata sullo sviluppo del suo carattere e della sua personalità; in breve, si è assistito a un nuovo potente ingresso in scena dell’idea del bene, e, con essa, della virtù quale via maestra per conseguire il (...) fine adeguato della vita umana. Il volume si propone di rendere conto – anche in correlazione al ruolo delle emozioni, ma non solo – del percorso filosofico della virtù: dall’indagine delle sue fonti “classiche”, all’inizio del suo declino nella modernità, al risorgere della sua vitalità negli ultimi decenni nelle diverse aree linguistico-culturali, tenendo anche conto delle differenti discipline con cui si è interfacciata. Esso non pretende di esaurire i percorsi e le suggestioni che una tematica così vasta presenta, né di coprirne tutta la storia; piuttosto, vuole rappresentare uno stimolo alla ricerca, ponendo in connessione tagli disciplinari e metodologici differenti per offrire una riflessione a tutto campo, che metta in dialogo studiosi provenienti da ambiti diversi ed apra nuove prospettive.Saggi di: Francesco Camera, Angelo Campodonico, Elisabetta Cattanei, Michel Croce, Elisa Cuttini, Marco Damonte, Elisa Grimi, Simona Langella, Alberto Masala, Alma Massaro, Letterio Mauro, Giacomo Samek Lodovici, Maria Silvia Vaccarezza, Paolo Vignola, Lodovica Maria Zanet, Matteo Zoppi.

“A fine collection of essays exploring, and in many cases extending, Jim Buchanan’s many contributions and insights to economic, political, and social theory.”– Bruce Caldwell, Professor of Economics, Duke University, USA"The overwhelming impression the reader gets from this very fine collection is the extraordinary expanse of James Buchanan's work. Everyone interested in economics and related fields can profit mightily from this book."– Mario Rizzo, Professor of Economics, New York University, USA This book explores the academic contribution of James (...) Buchanan, who received the Nobel Prize for economics in 1986. Buchanan’s receipt of the Prize is noteworthy because he was a maverick within the economics profession. In contrast to the preponderance of economists, Buchanan made little use of mathematics and no use of econometrics, preferring to used logic and language to insert his ideas into the scholarly community. Moreover, his ideas extended the domain of economic inquiry along many paths that numerous economists subsequently pursued. Buchanan’s scholarship brought economics and political science together under the rubric of public choice. He was also was a prime figure in bringing economic theory into closer contact with moral and social philosophy.This volume includes essays distributed across the extensive domain of Buchanan’s scholarly contributions, reflecting the range of his scholarly interests. Chapters will examine Buchanan’s scholarly work on public finance, social insurance, public debt, public choice, economic methodology, constitutional political economy, law and economics, and ethics and social theory. The book also examines Buchanan in relation to other prominent economists, both from the distant past and the recent past. (shrink)

YoungWilliam Thomas Jones, a friend and supporter of this journal since its inception, died on September 30, 1998, in Claremont, California, at the age of eighty-eight. Born in Natchez, Mississippi, Will was educated at Swarthmore, Oxford (as a Rhodes scholar), and Princeton. After a legendary teaching career spanning nearly fifty years, thirty-four at Pomona College and another fifteen at the California Institute of Technology, (...) Will retired in 1985. He published a host of articles and books, among them the highly regarded five-volume A History of Western Philosophy, now in its fourth edition. Will received numerous awards and honors, including Lippincott, Procter, Ford Faculty, and Guggenheim Fellowships; he was also a Phi Beta Kappa Visiting Scholar, and twice a Resident Scholar with the Rockefeller Foundation at Villa Servelloni. In 1969–70, he was President of the American Philosophical Association’s Pacific Division.In 1961, Will joined Karl Aschenbrenner, John D. Goheen, Paul O. Kristeller, Oskar Piest, Benson Mates, Ernest Moody, Richard H. Popkin, Herbert W. Schneider, and E. W. Strong (as chair) to form the Executive Committee (now Board of Directors) of the Journal of the History of Philosophy. The first issue of the JHP appeared some two years later.

We join Will’s family, friends, colleagues, and students in mourning the loss of a fine historian, philosopher, and teacher.Copyright © 1999 Johns Hopkins University Press... (shrink)

Here we discuss the challenge posed by self-organization to the Darwinian conception of evolution. As we point out, natural selection can only be the major creative agency in evolution if all or most of the adaptive complexity manifest in living organisms is built up over many generations by the cumulative selection of naturally occurring small, random mutations or variants, i.e., additive, incremental steps over an extended period of time. Biological self-organization—witnessed classically in the folding of a protein, or in the (...) formation of the cell membrane—is a fundamentally different means of generating complexity. We agree that self-organizing systems may be fine-tuned by selection and that self-organization may be therefore considered a complementary mechanism to natural selection as a causal agency in the evolution of life. But we argue that if self-organization proves to be a common mechanism for the generation of adaptive order from the molecular to the organismic level, then this will greatly undermine the Darwinian claim that natural selection is the major creative agency in evolution. We also point out that although complex self-organizing systems are easy to create in the electronic realm of cellular automata, to date translating in silico simulations into real material structures that self-organize into complex forms from local interactions between their constituents has not proved easy. This suggests that self-organizing systems analogous to those utilized by biological systems are at least rare and may indeed represent, as pre-Darwinists believed, a unique ascending hierarchy of natural forms. Such a unique adaptive hierarchy would pose another major challenge to the current Darwinian view of evolution, as it would mean the basic forms of life are necessary features of the order of nature and that the major pathways of evolution are determined by physical law, or more specifically by the self-organizing properties of biomatter, rather than natural selection.

This is a fine work that purports to serve as an introduction to philosophic problems surveyed from the historical perspective. Hartnack chooses to focus on a single work or theme of those philosophers who have significantly contributed to the development of philosophy starting with Heraclitus and ending with Wittgenstein. He renders concise and uncomplicated accounts that capture the nucleus of the problems. What makes this book stand out among so many other similar endeavors is that the expositions are not (...) only true to the problem but, refreshingly, they say neither too little nor too much. Rather they afford the reader a taste of the author’s wares whetting the appetite to further sample the original sources in hopes of finding the solutions to the problematics offered. For the freshman with little or no previous encounter with philosophy this can be an immeasurable bonus since too often he is victimized by arid and tedious readings. Hartnack makes good use of cross referencing providing the work with a thread of continuity, and it is only in his chapter on Kant’s epistemology that we note a deficiency in this area. Had he spelled out the influence of Hume’s skepticism on Kant’s Critique he might have approached the chapter in terms of the question which seems to be most central to Kant’s project, i.e., "Is metaphysics as a science possible?" rather than start out with an analysis of the antinomies that only indirectly point to this problem. However, if there is a deficiency in this chapter, it is offset by an excellent account of Kant’s moral philosophy. Notwithstanding this negative criticism plus the fact that there are several typographical errors, this is a scholarly accomplishment and deserves to be on the bookshelf of not only the beginning philosophy student who wishes to have a viable resource but also for those who have passed beyond this stage and wish to possess a valuable reference tool. Included at the end is a short but worthwhile bibliography.—K.R.M. (shrink)

The relationship between corporate social responsibility (CSR) and leadership has received considerable research attention in recent decades. While there have been several qualitative reviews, quantitative and systematic reviews of CSR–leadership links remain absent. The current paper seeks to address this gap by using a bibliometric method to analyze and visualize the evolution and research trends within the CSR–leadership domain. Drawing from a sample of 1432 peer-reviewed articles, we map the landscape of the CSR–leadership research domain and identify key developments and (...) patterns over the period 1994–2020. In addition to highlighting a range of publication trends including key theoretical influences, the findings also reveal an acceleration in the volume and breadth of CSR–leadership research. Seven subdomains (or clusters) are further identified (i.e., board characteristics, responsible leadership, emerging country context, team efficacy, CEO pay fairness, shareholder wealth, and cross-sector social partnership) and discussed based on the keywords using the log-likelihood ratio clustering algorithm. The analysis is further divided into three stages: namely, the initial stage (1991–2003), the rapid development stage (2004–2011), and the maturation stage (2012–present). These stages are used to present more fine-grained insights into the research patterns over time. We conclude by discussing implications of the bibliometric analysis and presenting several opportunities for future research. (shrink)

In a recent study of astrophysical “fine-tunings” (or “coincidences”), Robert Klee critically assesses the support that such astrophysical evidence might be thought to lend to the design argument (i.e., the argument that our universe has been designed by some deity). Klee argues that a proper assessment indicates that the universe is not as “fine-tuned” as advertised by proponents of the design arguments. We argue (i) that Klee’s assessment of the data is, to a certain extent, problematic; and (ii) (...) even if Klee’s assessment of the data is correct, it provides a necessary but not a sufficient response to the design argument. However, an adequate skeptical rejoinder to the design argument can be made by appealing to the anthropic principle. (shrink)

The greatest diversity of butterflies and their host plants occurs in tropical regions. Some groups of butterflies in the tropics exhibit monophagous feeding in the larval stage, exploiting only one family of plants; others are polyphagous, feeding on plants in two or more distinct families. The two major types of tropical habitats for butterflies, namely primary and secondary forests, offer very different evolutionary opportunities for the exploitation of plants as larval food. Butterflies are faced with the major logistical problem, as (...) are many other herbivorous insects, of depositing eggs on the correct plant for successful larval feeding. This paper, using the concepts of phenotype set and spatial patchiness of resources, attemps to make some predictions as to the optimal phenotypic systems for monophagous and polyphagous feeding in tropical butterflies, as related to the spatial patchiness of larval host plants in primary and secondary forests. In addition to the secondary compound chemistry of larval host plants as playing a role in the evolution of monophagy and polyphagy, the assumption is made that the spatial patchiness of host plants within and among different families also acts as a major factor in determining optimal ranges of phenotypes for different patterns of larval feeding. Owing to the high spatial patchiness of primary forest species of canopy trees and vines, it is predicted that butterflies exploiting these will be mostly polyphagous, whereas secondary forests having stable formations of fewer plant species and larger patches of these plants, will have mostly monophagous species. Forest understories may have both monophagous and polyphagous species, depending upon the layer of forest and the general type of understory (i.e. palmaceous or dicotyledonous). Field data on some groups of butterflies from tropical America support these predictions. Polyphagous butterflies are predicted to possess a genetic system of mixed morphs with a population being polymorphic as a whole; monophagous butterflies are predicted to have individuals all more or less similar genetically, and with a high amount of genic variation within individuals. Other forms of monophagy may evolve in species that are essentially monomorphic but with various mechanisms (physiological, developmental, behavioral) of phenotypic flexibility at the individual level. Although the environment is essentially coarse-grained for larvae since most are sedentary and polymorphism is an optimal adaptive strategy, the oviposition strategy of the adult must also be considered and some situations (i.e. forest canopy) have resources (host plants) distributed in a fine-grained fashion. Other forms of limited polyphagy may result from monomorphic genetic systems in which there is considerable phenotypic flexibility. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Whose Antigone? The Tragic Marginalization of Slavery by Tina ChanterM. D. UsherTina Chanter. Whose Antigone? The Tragic Marginalization of Slavery. Albany: State University of New York Press, 2011. xli + 233 pp. Cloth, $90; paper, $29.95.Tina Chanter’s book sets out to re-read Sophocles’ Antigone in light of two modern reworkings of the play from sub-Saharan Africa—Athol Fugard’s The Island (1974), which is based on an actual all-male performance (...) of Antigone by prisoners on Robben Island (where Nelson Mandela was incarcerated), and Fémi Òsófisan’s Tègònni: An African Antigone (1999), a version highlighting racial tensions that is set in British-colonial Nigeria. But Chanter’s book is about much more than that, as she spends a good deal of time critiquing, on the one hand, the interpretive tradition of Western psychoanalysis, which sees gender and kinship relations as the defining themes of the Oedipus cycle, while decrying, on the other, Hegelian readings that view Antigone as an aesthetically pure, ethical heroine caught between obligations to family and state. The thesis of the book is perhaps best captured in Chanter’s own words: “It turns out that the issues raised by Òsófisan and Fugard... far from being tangential to those of Sophocles, are inscribed at the very heart of the Oedipal cycle. Yet their inscription has proved difficult to read by interpreters of Antigone who have inherited ways of reading inflected by philosophical and psychoanalytic legacies, which are themselves implicated in imperialism, bolstered by new world slavery” (143). Chanter’s critique of the West’s reception of Antigone is often illuminating, but the proposition that colonialism per se is the culprit of blindered readings and that slavery lies [End Page 159] somehow at the heart of Sophocles’ original play fails to convince. There are disclaimers that this is not in fact the argument. For example: “The argument is [not] that Sophocles’ Oedipal cycle is really about the question of slavery” (xiii) and “I hope it is clear that my effort here is not to produce a universal narrative in which the truth about Antigone turns out to be that it is really about slavery” (144). But so much of Chanter’s discussion focuses on the topic of slavery—e.g., “A central task of the book is to demonstrate that Antigone’s discrimination of her brother Polynices from a slave is part of a larger complex of themes concerning the status of outsiders, foreigners, and slaves that informs the Oedipal cycle”(x)—that such comments read more like palinodes than as attenuations of the argument. The three whole paragraphs of unanswered, unsubstantiated rhetorical questions about the supposed centrality of slavery to the Antigone and its reception at pages 89–90 reinforce this impression.Chanter does, however, offer informed and sensitive readings of Fugard’s and Osófisan’s works (chaps. 3 and 4). These form the best parts of the book, to which end the plot synopses of those plays on pages 147–49 will be helpful to the reader who is unfamiliar with them. Also good is the analysis/critique of Hegel’s views on tragedy, and on the Antigone in particular (chap. 2). But the book is bloated at the ends: a 38-page preface is followed by a 27-page introduction. Add to that 46 pages of endnotes and the total is 111 pages of prolegomena and epilegomena, much of which is, in this reader’s judgement, parerga. What remains are 124 pages (of a total 235, excluding bibliography and index) of actual evidence and development of the thesis. This feature of the book is due in large part to repetitiveness: Chanter has some fine turns of phrase, to be sure, but statements made once or twice are repeated again and again throughout with no appreciable gain in thought, giving a snowball effect to the development of the argument, which at times is difficult to unpack. A lot of additional space is taken up by metadiscourse: e.g., “this book concerns itself with” (xxxvii); “my overarching approach” (20); “one of the aims of this book” (this on p. 22, after 38 pages of...

The thesis of this book is that Herbert Marcuse is "indispensable to the theory and practice of the New Left." The one-dimensional quality of contemporary everyday life is to be disrupted by a critical theory of society based upon the works of Karl Marx as interpreted and brought to bear upon the 20th Century. Hence, this collection of six New Left studies on Herbert Marcuse is called Critical Interruptions. The contributors are former students of Marcuse and all are younger than (...) thirty-five. The work is dedicated to Theodor W. Adorno and Ho Chi-Minh. The book is poorly edited; not only does the heavy Marcusean terminology make intelligibility slow; but poor rhetoric, grammar and punctuation also add to the slowness of the pace. The content of the essays, however, is uniformly very worthwhile and the book deserves a careful reading. The Marcuse Festschrift of 1967, edited by Kurt H. Wolff and Barrington Moore, Jr., entitled The Critical Spirit, was a collection of essays "in honor of Herbert Marcuse." This 1970 book, Critical Interruptions, is addressed to the exposition, up-dating and critique of Marcuse himself. Therefore, this present work is of immediate help to all readers and students of Marcuse. Paul Breines, the editor, wrote the first essay, "From Guru to Spectre: Marcuse and the Implosion of the Movement"; this is a history of Marcuse's relation to the New Left over the past few years. The second essay, "Individuation as Praxis," by Shierry M. Weber, is an incisive and insightful critique of the New Left while studying the meaning of praxis, the personal dimensions of individuality and exploring realistic alternatives for a viable counter culture. "Reversals and Lost Meanings" by Russell Jacoby is a short attempt at dialectics. William Leiss' study, "The Critical Theory of Society: Present Situation and Future Tasks," is a fine review of the major representatives of the Frankfurt School of social philosophers. "On Sexuality and Politics in the Work of Herbert Marcuse" by John David Ober, explains the continuity and development in Marcuse's thought on sexuality from Eros and Civilization through One-Dimensional Man. Finally, the last essay, "One-Dimensionality: The Universal Semiotic of Technological Experience" by Jeremy J. Shapiro is an extended commentary on Marcuse's most recent thought as applied to the advancing technology of the age. The editor openly disclaims any inner unity to the six essays. The studies, however, reveal that at least these six students of Marcuse from the New Left understand the Master very well and are able to extend his thought successfully to key contemporary issues. At the end, there is a greater unity to the book than the editor anticipated.--E. W. R. (shrink)

We analysed research ethics committee (REC) letters. We found that RECs frequently identify process errors in applications from researchers that are not deemed “favourable” at first review. Errors include procedural violations (identified in 74% of all applications), missing information (68%), slip-ups (44%) and discrepancies (25%). Important questions arise about why the level of error identified by RECs is so high, and about how errors of different types should be handled.

Although very young children have unprecedented access to touchscreen devices, there is limited research on how successfully they operate these devices for play and learning. For infants and toddlers, whose cognitive, fine motor, and executive functions are immature, several basic questions are significant: Can they operate a tablet purposefully to achieve a goal? Can they acquire operating skills and learn new information from commercially available apps? Do individual differences in executive functioning predict success in using and learning from the (...) apps? Accordingly, 31 2-year-olds were compared with 29 3-year-olds using two commercially available apps with different task and skill requirements: a shape matching app performed across 3 days, and a storybook app with performance compared to that on a matched paper storybook. Children also completed the Minnesota Executive Functioning Scale. An adult provided minimal scaffolding throughout. The results showed: toddlers could provide simple goal-directed touch gestures and the manual interactions needed to operate the tablet after controlling for prior experience with shape matching, toddlers’ increased success and efficiency, made fewer errors, decreased completion times, and required less scaffolding across trials, they recognized more story content from the e-book and were less distracted than from the paper book, executive functioning contributed unique variance to the outcome measures on both apps, and 3-year-olds outperformed 2-year-olds on all measures. The results are discussed in terms of the potential of interactive devices to support toddlers’ learning. (shrink)
