Decades of psychological research have been aimed at modeling how people learn features and categories. The empirical validation of these theories is often based on artificial stimuli with simple representations. Recently, deep neural networks have reached or surpassed human accuracy on tasks such as identifying objects in natural images. These networks learn representations of real‐world stimuli that can potentially be leveraged to capture psychological representations. We find that state‐of‐the‐art object classification networks provide surprisingly accurate predictions of human similarity judgments for (...) natural images, but they fail to capture some of the structure represented by people. We show that a simple transformation that corrects these discrepancies can be obtained through convex optimization. We use the resulting representations to predict the difficulty of learning novel categories of natural images. Our results extend the scope of psychological experiments and computational modeling by enabling tractable use of large natural stimulus sets. (shrink)

First published in 1975, this is a book of general intellectual interest about the role of the university in contemporary society and that of university teachers in relation to their subjects, their students, and their wider political commitments. Alan Montefiore offers preliminary analyses of the family of concepts most often invoked in discussions of these problems, taking the central dispute to be between those who hold a 'liberal' view of the university and those who regard this notion as illusory, dishonest (...) or undesirable. Six academics, representing, discuss issues of substantive conflict in light of Montefiore's initial distinctions. The volume is of particular interest to students of political and social philosophy, and political and educational theory. It is also intended for a wider readership among those who care about the political status of the universities and recognize the importance and difficulty of the problems involved in this. (shrink)

Equilibrium explanations use an equilibrium to represent and explain a system’s dynamic behavior. They provide a system with the property of global stability: a system will converge towards and remain in equilibrium regardless of its initial conditions and dynamic process. Thus, equilibrium explanations are generally treated as non-causal explanations. There are two claims subsumed under that comprehensive thesis. The first claim is that equilibrium explanations do not identify any causes because a system with global stability resists manipulation. The second claim (...) is that even if equilibrium explanations do identify causes by manipulation, those causes are embedded in a system’s deeper, underlying structural relationships, and those causes are irrelevant to explaining a system’s behavior. Only the system’s structural relationships are relevant. But equilibrium explanations are not monolithic. I compare dynamic systems with multiple, competing equilibria to systems with a globally stable equilibrium. Equilibrium explanations of the former use intervention on a system’s initial conditions and dynamic process to manipulate equilibria, which identifies causes. Furthermore, a system’s initial conditions and dynamic process are relevant to explaining why one equilibrium is selected instead of another. I then apply these lessons to systems with a globally stable equilibrium and discuss when their corresponding equilibrium explanations have a proper role in the parent sciences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Callimachus and His CriticsFrederick T. GriffithsAlan Cameron. Callimachus and His Critics. Princeton: Princeton University Press, 1995. xiv + 534 pp. Cloth, $49.50, £37.50."Elegy was the great preoccupation of the age of Callimachus, and it was naturally the style appropriate for elegy rather than epic that Callimachus addressed in the prologue to his own original and polemical new elegy" (437). Professor Cameron's keenly anticipated argument (outlined in TAPA 122 (...) [1992] 305-12) does not disappoint, especially now that he includes among the "critics" not only such ancient "Telchines" as Asclepiades and Posidippus but also the Roman Callimacheans and "moderns with Hesiodic initiations on the brain" (415). To counter "the curious modern preoccupation with Hellenistic epic and epyllion" (ix), seen most starkly in interpretation of Catullus and the Augustans, Cameron interweaves two ambitious projects.First, the organizing argument is a reconstruction and dating of the Aetia so as to establish that the prologue (frag. 1 Pf.) introduced books 1 and 2 ca. 270 [End Page 339] B.C. amid debates about contemporary elegy. In place of the now generally discredited "feud" with Apollonius over monumental epic, Cameron posits a quarrel with Asclepiades and Posidippus over the epicizing Antimachean mode of elegy. The prologue is not a recusatio of grand epic (a Roman preoccupation); indeed, "... there is no mention of epic in the Aetia prologue" (457), and elegy would be a curious medium for dictating taste in hexameter. Nor does the prologue claim novelty for the Aetia as catalogue-style "Hesiodic elegy," which had been in fashion since the Lyde, and indeed so much so that "it was pseudo-Hesiodic rather than pseudo-Homeric writing that aroused Callimachus's ire" (363). The "Telchines" are the admirers of the Lyde, a poem that Callimachus assails as an "epic pastiche" (483), a monotonous, and the stylistic antithesis of the interesting subjectivity and personal voice demonstrated in his own Cydippe (ca. 279-274). For having compromised the distance of elegy from epic, Antimachus is left pointedly unnamed next to Mimnermus and Philitas (316) and further overshadowed by allusion to Aratus (in, frag. 1.11) as the proponent and paragon of. In sum, the prologue's polemic lies more completely within the moment and between the lines than has been suspected, and entirely within elegy but outside of theory: "So Callimachus's famous literary theories do not really amount to much-as theories" (452).Second, to understand how the Aetia speaks for its age we must understand the age rightly. To provide "a prolegomena to the study of Hellenistic (and so also Roman) poetry" (ix) Cameron pauses frequently in his reconstruction of the Aetia to launch diatribes against the folly of reducing Hellenistic poetry to the aestheticism and obscurantism of the "ivory tower," or to genre inversion (contra Rossi), Buchpoesie (contra Bing), or, worst of all, some "contest of Homer and Hesiod" about big and small epics. This rarefied "Alexandria" existed first in Rome and at a great remove from the continuities of Hellenic culture that shaped Callimachus' "real literary context, a world of cities as well as courts, a world of private symposia and public festivals" (ix). Multibook epics were too rare (contra Ziegler) to require recusatio, while the popularity of short hexameter poems precluded controversies such as are implied by the term of "epyllion" (contra Gutzwiller) or imputed to Theocritus (Id. 7, 13, and 22) and Callimachus (H. Apollo and Hecale). "To judge from the debate about the Lyde, it was elegy that preoccupied the more reflective poets and critics of the age" (451).Only a scholar with Cameron's range, good ear, and courage could undertake a two-pronged offensive of this sort, which is not less "original and polemical" than the elegy it celebrates. Recently published papyri, Byzantine misreaders, and the shifty tribe of epigrammatists have all been marshaled with equal authority for what is in part the elegiac pre-history to his distinguished The Greek Anthology from Meleager to Planudes (Oxford 1993). By the nature of the fragmentary evidence, both the elegy-centered age and its important (if not definitive) Aetia can be reconstructed only at the level of hypothesis, and readers will differ as...

Critics of synergism often complain that the view entails Pelagianism, and so, critics think, monergism looks like the only live option. Critics of monergism often claim that the view entails that the blame for human sin ultimately traces to God. Recently, several philosophers have attempted to chart a middle path by offering soteriological accounts which are monergistic but maintain the resistibility of God’s grace. In this paper, we present a challenge to such accounts of the resistibility of grace, namely that (...) they imply that human beings are praiseworthy for omitting to resist God’s grace. Even if such views escape Pelagianism as it is typically defined, they fail to avoid the worry at the heart of prominent criticisms of Pelagianism concerning the praise for a human being’s salvation. At the end of the paper, we suggest three possible solutions to this problem. (shrink)

Most cognitive psychology experiments evaluate models of human cognition using a relatively small, well-controlled set of stimuli. This approach stands in contrast to current work in neuroscience, perception, and computer vision, which have begun to focus on using large databases of natural images. We argue that natural images provide a powerful tool for characterizing the statistical environment in which people operate, for better evaluating psychological theories, and for bringing the insights of cognitive science closer to real applications. We discuss how (...) some of the challenges of using natural images as stimuli in experiments can be addressed through increased sample sizes, using representations from computer vision, and developing new experimental methods. Finally, we illustrate these points by summarizing recent work using large image databases to explore questions about human cognition in four different domains: modeling subjective randomness, defining a quantitative measure of representativeness, identifying prior knowledge used in word learning, and determining the structure of natural categories.

In an era defined by the global surge in the adoption of AI-enabled technologies within public administration, the promises of efficiency and progress are being overshadowed by instances of deepening social inequality, particularly among vulnerable populations. To address this issue, we argue that democratizing AI is a pivotal step toward fostering trust, equity, and fairness within our societies. This article navigates the existing debates surrounding AI democratization but also endeavors to revive and adapt the historical social justice framework, maximum feasible (...) participation, for contemporary participatory applications in deploying AI-enabled technologies in public administration. In our exploration of the multifaceted dimensions of AI’s impact on public administration, we provide a roadmap that can lead beyond rhetoric to practical solutions in the integration of AI in public administration.

This book is a collection of edited interviews from The Free Will Show-a podcast that provides a beginner-friendly introduction to free will while also highlighting recent developments on the topic. The book includes original material as well, including an introduction to the interviews and an afterward with reflections on the podcast by the authors (who are cohosts of The Free Will Show). The book also includes a bibliography and suggestions for further reading after each interview and a glossary of terms (...) at the end of the book. The book will serve well either as a textbook or as an accessible entry-point to the free will debate, whether for an interested non-specialist or a philosopher who works in another area. The first half of this book introduces the main issues and arguments in philosophical debates about free will, including various apparent threats to free will (fatalism, foreknowledge, and determinism), the Consequence Argument, and the problem of luck, among others. The second half of this book introduces the main positions in the debate about free will and determinism, including several varieties of libertarianism and compatibilism, a version of free will skepticism, and some other positions that do not fit neatly into these categories.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Theocritus and the Archaeology of Greek PoetryFrederick T. GriffithsRichard Hunter. Theocritus and the Archaeology of Greek Poetry. Cambridge: Cambridge University Press, 1996. xii 1 207 pp. Cloth, $54.95.To locate Theocritus on the evolving map of third-century culture, Richard Hunter forgoes mapmaking itself in favor of the scattered “sites” found in seven nonbucolic mimes, hymns, and erotic poems. He introduces these lively and learned essays with the observation that (...) “too often ‘Hellenistic poetry’ is treated as an entity in which the whole is easier to grasp, and in some ways more interesting, than the parts” (x). Theocritus’ Nachleben deepens the distortion: “Concentration on Theocritus’ ‘bucolic poems’ has tended to obscure the fact that the range and variety of his poems are very characteristic of the poetic milieu of the period” (20). Successive chapters find Theocritus crossing paths with Apollonius Rhodius, Aratus, Herodas, and Callimachus. As ever, all roads lead back to Homer, but Hunter pointedly directs our view elsewhere. Different as they are, Helen (Idyll 18), Hiero II (16), the Alexandrian housewives (15), the Dioscuri (22), and three languishing paederasts (12, 29, 30) commonly witness to the third century’s interest in the “song culture” of the archaic age, an age with many centers and patrons, a “rich tapestry of poetic forms” (p. 2), and a performance culture not overshadowed by the dramatic festivals of Athens.Philology’s erstwhile handmaiden, archaeology, presides as a tenth Muse both over Theocritus’ learned “recuperation” of archaic song and, at another level, over Hunter’s revival of these underappreciated Idylls. Even “the poems themselves dig deeply into a (real or constructed) archaic world for much of their matter and their form” (196). The figure of science gestures to his seamless [End Page 468] integration of papyrology, dialectology, and metrics and inevitably digs up artifacts with more cultural residue than some “intellectual exercise divorced from any meaningful social or ideological context” (11). Hunter undermines the “ivory tower” currently under siege by Alan Cameron and others. The book’s signal contribution comes, however, from questions of “performative context” (4) that may betray the trope. “Musical archaeology” (101) creaks in describing Theocritus’ “rescue” of archaic musical forms. “Locating the Site” (chapter 1) in fact excavates performance and dialect more than anything else. What Hunter’s gritty “archaeology” importantly is not is the stale, library-bound trope of “aetiology.” His introduction proceeds (“Toward Theocritus,” 1–13) via the Fragmentum Grenfellianum and Heracles’ nursery (24.1–9) rather than from Callimachus’ Aetia, which as a project does not figure in these six essays. It is Philitas and, less conventionally, Erinna and Asclepiades who pave the way for Theocritus (“The Poetic Context,” 14–28). Chapter 1 ends with an important survey of “the languages of Theocritus” (28–45), which can be recommended to students and general readers as an introduction to literary dialects in Theocritus, here presented with rare sensitivity to their literary use.Were Hunter starting from “life and times” rather than “site,” familiar topics would at once impose themselves: patronage, religion, the pandectic hexameter, and the elite appropriation of “subliterary” forms. These obligations are agreeably distributed over the five chapters of readings, or perhaps one might better say, “five performances.” For Hunter never marches through an Idyll from end to end but instead selects, restages, and defamiliarizes key passages against the backdrop of, inter alia, recently recovered papyri, hieroglyphic decrees, Old and New Comedy, instrumental performance, meditations on mimesis and mummification, and snatches of Alcman or Theognis not already fossilized in commentary. Of what should be a conventional ag ¬ n between thumos and reason in Idyll 12 he observes: “The irony of the poem lies in the fact that it is the speech of the thumos which is then characterized by an appeal to reason, whereas the lover hectors his thumos like a comic father lecturing his wayward son” (182). We were not expecting Terence: “Cf. perhaps Ter. Ad. 685–95.” With his sharp ear, timing, and fluency in all ages of Greek and Roman verse, Hunter has more than enough fresh insights to hold the attention of both generalists and Theocriteans.“‘All the Twos’: Idyll 22” (chapter 2) works from astute...

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 122.3 (2001) 440-444 [Access article in PDF] Arnd Kerkhecker. Callimachus' Book of Iambi. Oxford: Clarendon Press, 1999. xxiv + 334 pp. 5 plates. Cloth, $85.00. The Iambi have been slow to profit from Callimachus' recent popularity, even though our much changed sense of the archaic iambicists, especially Archilochus, makes the collection due for a major reassessment. In Hellenistica Groningana 1 (1993), the Iambi claim scarcely (...) two pages out of two hundred, and in Alan Cameron's iconoclastic Callimachus and His Critics (1995) a bit more than five out of five hundred. Though Callimachean polyeideia cannot be well understood without the Iambi, readers continue to be daunted by these difficult fragments, which in places are little more than a tale told by a diegete, signifying nothing very certain.Now, twenty years after Dee Lister Clayman's fine, short survey of the Iambi, we have not one, but two, book-length readings of the collection. As if the [End Page 440] poet had suddenly risen to sow discord while preaching eunoia, Kerkhecker's formidable Oxford dissertation of 1997 comes to us already in pitched disagreement with Benjamin Acosta-Hughes's Stanford thesis (1995), forthcoming from the University of California Press as Polyeideia: The Iambi of Callimachus and the Archaic Iambic Tradition. Callimachus would not have it any other way.These rival projects complement each other as well as disagree. Acosta-Hughes accommodates the Greekless reader with translations of the Diegesis and the ten Iambi he discusses; in addressing classicists generally, Kerkhecker provides close guidance to the papyri for nonspecialists. As his title indicates, Acosta-Hughes focuses on aesthetics; Kerkhecker revives J. K. Newman's question, "Do the Iamboi make no moral appeal?" (9). Where Acosta-Hughes reads the collection by thematic groupings, Kerkhecker reads the Iambi in sequence and, importantly, as a single composition in thirteen parts. The operative word in his title is "book." I limit myself below to Kerkhecker's monograph, which provides an indispensable ancilla to and partial updating of Pfeiffer's edition, and which constructs as strong a case as can be imagined, on the current evidence, for the designed unity of the Iambi: "Callimachus is not just collecting and editing his own poems, much like those of others; he is composing with the collection in mind, with a view to the scholarly edition, for the Book" (290).Kerkhecker presents an impressive range of mastery, from papyrology to connoisseurship of a later Aufklärungszeitalter. Wieland, Lessing, Herder, and even Fielding offer a reminder of what was once at stake in debates about art. Kerkhecker writes lucid, lively, and often witty prose that is worthy of his tastes and subject. To counter the current age of theory, he reasserts a reminiscently Enlightenment faith in the text; "social text" and "intertext" join Euhemerus in silence and disgrace. Kerkhecker reads the Iambi as a self-enclosed poetic universe, without relying on speculations about chronology, Ptolemaic patronage, designed correspondence to the Aetia, Horatian imitation, or Cameron's questions about performance. On Greek "poetry books," Cameron and Kerkhecker stand in diametrical opposition. In Kerkhecker's view, Callimachus' book articulates a "new Iambic Spirit" (293) by looking inward: to manners more than morals, to Selbstkritik rather than Zeitkritik, and to self-parody beneath feigned polemic. As in later ages, the mark of such hermetic and self-conscious Buchdichtung is multilayered irony.Reconstructions of Greek poetry books proceed against stiff resistance, but Kerkhecker's monograph securely earns a place on the shelf near Pfeiffer by the rigor and erudition of his interpretation on all levels. Chapters on individual Iambi begin with a reassessment of Pfeiffer's edition based on Kerkhecker's collation of the papyri and with an explanation of Pfeiffer's rationale in combining papyri, quotations, and other evidence. Kerkhecker discusses unpublished readings by Coles, Maas, and Rea, and differs in some sixty places from Pfeiffer, whose authority survives this scrutiny intact. Until the now faded Oxyrhynchus Papyri VII.1011 can be reedited, the reader has a full and fair assessment of how the evidence stands. Kerkhecker forthrightly discloses the extent of his own...

A limiting factor in ethics education in medical training has been difficulty in assessing competence in ethics. This study was conducted to test the concept that content analysis of pediatric residents’ personal reflections about ethics experiences can identify changes in ethical sensitivity and reasoning over time. Analysis of written narratives focused on two of our ethics curriculum’s goals: 1) To raise sensitivity to ethical issues in everyday clinical practice and 2) to enhance critical reflection on personal and professional values as (...) they affect patient care. Content analysis of written reflections was guided by a tool developed to identify and assess the level of ethical reasoning in eight domains determined to be important aspects of ethical competence. Based on the assessment of narratives written at two times (12 to 16 months/apart) during their training, residents showed significant progress in two specific domains: use of professional values, and use of personal values. Residents did not show decline in ethical reasoning in any domain. This study demonstrates that content analysis of personal narratives may provide a useful method for assessment of developing ethical sensitivity and reasoning. (shrink)

Normative game theory unsatisfactorily explains rational behavior. Real people do not behave as predicted, and what is prescribed as rational behavior is normally unattainable in real-life. The problem is that current normative analysis does not account for people's cognitive limitations – their bounded rationality. However, this paper develops an account of bounded rationality that explains the rationality of more realistic behavior. I focus on the Centipede Game, in which boundedly rational players explore and test others' immediate behavior, until they can (...) apply limited backward induction. The result is that the game has a solution in the form of a subjective Nash equilibrium, which boundedly rational players can possibly realize. (shrink)

Policies promoted and adopted for allocating ventilators during the COVID-19 pandemic have often prioritised healthcare workers or other essential workers. While the need for such policies has so far been largely averted, renewed stress on health systems from continuing surges, as well as the experience of allocating another scarce resource—vaccination—counsel revisiting the justifications for such prioritisation. Prioritising healthcare workers may have intuitive appeal, but the ethical justifications for doing so and the potential harms that could follow require careful analysis. Ethical (...) justifications commonly offered for healthcare worker prioritisation for ventilators rest on two social value criteria: instrumental value, also known as the ‘multiplier effect’, which may preserve the ability of healthcare workers to help others, and reciprocity, which rewards past usefulness or sacrifice. We argue that these justifications are insufficient to over-ride the common moral commitment to value each person’s life equally. Institutional policies prioritising healthcare workers over other patients also violate other ethical norms of the healthcare professions, including the commitment to put patients first. Furthermore, policy decisions to prioritise healthcare workers for ventilators could engender or deepen existing distrust of the clinicians, hospitals and health systems where those policies exist, even if they are never invoked.
