Human experts are the source of knowledge required to develop computer systems that perform at an expert level. Human beings are not, however, able to reliably express what they know. As a result, experts often develop non-authentic accounts of their own expertise. These accounts, here termed reconstructed methods of reasoning, lead to computer systems that perform at a high level of proficiency but have the disadvantage that they often do not reflect the heuristics and processing constraints of a system user. (...) Reconstructed methods of reasoning are compared with authentic methods derived from the study of expert human behavior. Tests are proposed to establish the authenticity of reasoning methods and examples from medical diagnosis are used to illustrate how authentic methods of reasoning can be incorporated into an expert computer system.

An investigation is presented in which a computer simulation model (DIAGNOSER) is used to develop and test predictions for behavior of subjects in a task of medical diagnosis. The first experiment employed a process‐tracing methodology in order to compare hypothesis generation and evaluation behavior of DIAGNOSER with individuals at different levels of expertise (students, trainees, experts). A second experiment performed with only DIAGNOSER identified conditions under which errors in reasoning in the first experiment could be related to interpretation of specific (...) data items. Predictions derived from DIAGNOSER's performance were tested in a third experiment with a new sample of subjects. Data from the three experiments indicated that (1) form of diagnostic reasoning was similar for all subjects trained in medicine and for the simulation model, (2) substance of diagnostic reasoning employed by the simulation model was parable with that of the more expert subjects, and (3) errors in subjects' reasoning were attributable to deficiencies in disease knowledge and the interpretation of specific patient data cues predicted by the simulation model.

The work presented here investigates the process by which one group of individuals solves the problem of detecting deceptions created by other agents. A field experiment was conducted in which twenty‐four auditors (partners in international public accounting firms) were asked to review four cases describing real companies that, unknown to the auditors, had perpetrated financial frauds. While many of the auditors failed to detect the manipulations in the cases, a small number of auditors were consistently successful. Since the detection of (...) frauds occurs infrequently in the work of a given auditor, we explain success by the application of powerful heuristics gained from experience with deceptions in everyday life. These heuristics implement a variation of Dennett's intentional stance strategy, which is based on interpreting detected inconsistencies in the light of the Deceiver's (i.e., management's) goals and possible actions. We explain failure to detect deception by means of perturbations (bugs) in the domain knowledge of accounting needed to apply these heuristics to the specific context of financial statement fraud. We test our theory by showing that a computational model of fraud detection that employs the proposed heuristics successfully detects frauds in the cases given to the auditors. We then modify the model by introducing perturbations based on the errors made by each of the auditors in the four cases. The resulting models account for 84 of the 96 observations (i.e., 24 auditors × four cases) in our data. (shrink)

This is an analysis of the nature, causes and consequences of the crisis of modern society. Professor Sorokin asserts that the whole of modern culture is undergoing a period of transition brought on by the struggle between the forces of the largely outworn materialistic order and the emerging, creative forces of a new idealistic order. On the outcome of this struggle, the author contends, rests the progress and survival of mankind.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Tragic Vision of African American ReligionPaul E. CapetzThe Tragic Vision of African American Religion Matthew V. Johnson New York, N.Y.: Palgrave Macmillan, 2010. 189 pp. $75.00Matthew Johnson’s profound book The Tragic Vision of African American Religion sheds new light upon the distinctive nature of African American religion. Adequate interpretation of this topic requires understanding the traumas inflicted upon Africans sold into slavery, their existential predicaments (...) before and after emancipation, and the ongoing plight of their descendants whose psyches have been indelibly scarred by this traumatic history. Johnson avails himself of the resources of philosophical theology, psychoanalytic theory, and literary criticism to argue his thesis that African American religion expresses a tragic vision of reality. Besides providing an illuminating analysis of the traumatic experience underlying this religious vision, Johnson presents a compelling constructive proposal as to the broader implications of his thesis for Christian theology at large.As a student of David Tracy and Langdon Gilkey, Johnson sees the necessity for rigorous philosophical reflection in theology. Because the spirituality of the black church stands in some real tension with the traditional theological categories inherited from Europe, Johnson proceeds with “a phenomenological orientation grounded in a philosophical hermeneutical approach” that allows him to excavate the traumatic experiences informing this spirituality (4). He skillfully uses the concepts of mourning, loss, longing, and desire developed in psychoanalytical theory to probe the significance of trauma for grasping the dynamics of African American spirituality. He engages literary criticism and argues convincingly for a distinction between “tragedy” as a literary genre and the tragic vision it articulates. Indeed, the tragic vision is prior to tragedy. The tragic is not the encounter with meaninglessness per se but “the always already aesthetic representation of the encounter, which preserves its terrible truth in a transfigured vision of reality” (6). This vision affirms life while facilitating “the recognition and embrace of the darker, more fundamental truths of life” (7).Cognizant that other theologians have declared the incompatibility of Christian faith with a tragic vision of reality, Johnson believes otherwise. He insists that the tragic is fundamental to human experience as such, although it is frequently evaded by strategies of foreclosure—including those of Christian theology—that falsify the experience. Yet the distinctive thing about the black religious experience is the way African Americans made the Christian faith [End Page 215] their own by transforming it at a deep spiritual level through their tragic vision. Mildly critical of previous formulations of black theology, Johnson contends that this involved much more than the affirmation that God cares about the sociopolitical liberation of oppressed people. The Christian tragic vision of the black experience offers the possibility of a new basis for “theology in an African American key” (6). Since he understands himself primarily as a Christian theologian, however, Johnson addresses an audience consisting of more than fellow black theologians. He rightly highlights a profound truth that white theologians have largely failed to grasp: the contribution of the black church “transcends the confines of African American culture to speak meaningfully to a Christian faith struggling to remain viable in a meaningful way” (10).James Cone once issued this challenge: “Why don’t white theologians make racism their issue?” White theologians who ponder Johnson’s book will begin to understand the full import of this challenge: by opening ourselves unreservedly to the pain of our black sisters and brothers, we may discover anew the meaning of that genuine humanity to which the gospel summons all people. A theological reformulation of Christian faith as tragic in the light of the traumas of the black experience could occasion a much needed reformation of the white churches in America.Paul E.

Background: Therapeutic misconception, the misunderstanding of differences between research and clinical care, is widely prevalent among non-incarcerated trial participants. However, little attention has been paid to its presence among individuals who participate in research while incarcerated. Methods: This study examined the extent to which 72 incarcerated individuals may experience therapeutic misconception about their participation in one of six clinical trials, and its correlation with participant characteristics and potential influences on research participation. Results: On average, participants endorsed 70% of items suggestive (...) of therapeutic misconception. The tendency toward therapeutic misconception was significantly higher among African Americans and Latinos compared to Whites, among older and less educated participants, and among enrollment in a substance-abuse-related trial; it was also correlated with a belief that the trial was the only way to obtain needed treatment. Conclusions: Therapeutic misconception may be particularly high among select incarcerated individuals and is associated with a perceived lack of treatment options. Further examination of therapeutic misconception among incarcerated research participants is needed. (shrink)

Mary Wollstonecraft was one of the most influential and controversial women of her age. No writer, except perhaps her political foe, Edmund Burke, and her fellow reformer, Thomas Paine, inspired more intense reactions. In her brief literary career before her untimely death in 1797, Wollstonecraft achieved remarkable success in an unusually wide range of genres: from education tracts and political polemics, to novels and travel writing. Just as impressive as her expansive range was the profound evolution of her thinking in (...) the decade when she flourished as an author. In this collection of essays, leading international scholars reveal the intricate biographical, critical, cultural, and historical context crucial for understanding Mary Wollstonecraft's oeuvre. Chapters on British radicalism and conservatism, French philosophes and English Dissenters, constitutional law and domestic law, sentimental literature, eighteenth-century periodicals and more elucidate Wollstonecraft's social and political thought, historical writings, moral tales for children, and novels.

All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Culture and Enlightenment are the two words that best characterise the essence of György Markus's career, in whose honour this book is published. Markus devoted the last twenty years of research towards a theory of cultural objectivations and their pragmatics, and the great depth of his knowledge of the history of culture and philosophy informs all his teaching and writing. The pursuit of Enlightenment ideals attains reflective self-consciousness in Markus' works; forged in the knowledge of its own historicity, of the (...) embeddedness of rationalities in culture and in an awareness of the paradoxes that cling to the conscious affirmation of ideals which are no longer self evident or beyond questioning. In taking up the challenge of these paradoxes, Markus spans the whole history of modern philosophy and culture with a matchless authority.This book draws together contributions from leading figures in contemporary philosophy, who are also friends, colleagues and former students of György Markus. The book is divided into two sections: the first presents critical assessments of various aspects of Markus' wide-ranging works; the second presents contributions in celebration of his influence and his wide interests. In their critical assessment of Markus' work and in the demonstration of his influence, the contributors hope to convey something of the breadth and something of the excitement of doing philosophy in the company of György Markus.

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Much later he wrote to Dr. Johnson in America, saying that he did not have the energy to do something so disagreeable as writing the same thing twice? This manuscript contained Berkeley's ethics and metaphysics, but in spite of its (...) loss, there is much to be learned about Berkeley's moral philosophy from his extant writings. Surprisingly, very little has been written about Berkeley's ethics, and what has been written usually concentrates on Passive Obedience and virtually ignores the rest of his worksY Most of the terminology now used to classify and criticize ethical theories was, of course, unknown to Berkeley. In spite of this, much of what he says may be fruitfully compared with some of the claims of modern ethicists.

Berkeley was first and last a Christian clergyman, and he therefore believed in the existence of a personal, wise, and benevolent God whose being was relevant to our daily lives. He was convinced that the natural world provides evidence for this belief, evidence as sound as that which we have for the existence of other minds. Given that the esse of objects consists in their being perceived, that only minds are active, and that no human perceiver perceives all things at all times, it follows that a cosmic mind maintains the universe it created. Moreover, the system of nature is not random, but regular; it is, in fact, a divine language in which God makes his intentions known to us, and demonstrates his wisdom... (shrink)
