For the safe and economical construction of embankment dams, the mechanical behaviour of the rockfill materials used in the dam’s shell must be analyzed. The characterization of rockfill materials with specified shear strength is difficult and expensive due to the presence of particles greater than 500 mm in diameter. This work investigates the feasibility of using an extreme gradient boosting computing paradigm to estimate the shear strength of rockfill materials. To train and validate the proposed XGBoost model, a total of (...) 165 databases obtained from the literature are chosen. The XGBoost model was compared against support vector machine, adaptive boosting, random forest, and K-nearest neighbor models described in the literature. XGBoost beats SVM, RF, AdaBoost, and KNN models in terms of performance evaluation metrics such as coefficient of determination, Nash–Sutcliffe coefficient, and error in the root mean square ratio to the standard deviation of the measured data. The results demonstrated that the XGBoost model has the highest prediction performance with, followed by the SVM model with, RF, the AdaBoost model with and the KNN model with. A sensitivity analysis has been conducted to ascertain the impact of each investigated input parameter. This study demonstrates that the established XGBoost model for estimating the shear strength of rockfill materials is reliable. (shrink)

Commercialism first became a major problem for medicine in the decade of the 1970s, when huge quantities of new money began to flow into the healthcare system, as a result of Medicaid and Medicare, and the rapid expansion of private, employer-based insurance. Of course, physicians benefited, but most of this new money went to insurance plans and medical care delivery institutions, like hospitals, nursing homes, diagnostic services, and ambulatory care facilities of many kinds. Many of these were newly established for-profit (...) businesses. A vast number of satellite enterprises sprang up to serve the growing needs of the new businesses by providing services like marketing and advertising, brokering, consulting, information technology, financial services, case and disease management, billing and collecting, and so forth.

A definition of ?alienation? is proposed which is a rational reconstruction of the term as it is used in primarily moral contexts. Special attention is given to the Marxist tradition. It is argued that the earliest, moral form of Marx's economic determinism can be expressed in terms of the principle of the sufficiency of unalienated labor. In this connection four main kinds of alienation are distinguished. In the final section, it is argued that while ?alienation? has and should have an (...) important theoretical role in the context of moral discourse, social scientists, and in particular sociologists, would be better off if they eliminated ?alienation? from their scientific vocabulary.

The arguments contained in books criticizing American social scientists by C. Wright Mills ( The Sociological Imagination) and Bernard Crick (The Science of American Politics) are discussed, compared and criticized. It is argued that Mills' criteria of evaluation and constructive alternatives to the tendencies he criticizes are immeasurably sounder than those found in Crick's book. An effort to supplement Mills' argument by providing a more explicit statement of its moral underpinnings is made. Finally, it is argued that though both critiques (...) have serious empirical flaws, the authors have undeniably demonstrated that important tendencies for irresponsible thought and action do exist within the American social sciences.

The idea of human rights gained prominence at a time when the rising bourgeoisie viewed the state as the main obstacle to commercial expansion, private property as the major protection against dependency, and material scarcity as an indelible condition of society. As moral concepts are largely shaped by the social forces that call them into being, it is not surprising that the very language of rights was early tailored to suit the needs of an expanding, acquisitive, increasingly powerful segment of (...) society.

Examination of human activities and their outcomes is a basic function of philosophy. Historically such examination has tended to conform to one of two patterns.

Professor Toynbee observes in his Study of History that as he walked down Whitehall one day in the spring of 1918, and passed the Board of Education offices which had been commandeered for a new department of the War Office, “improvised in order to make an intensive study of trench warfare,” he found himself repeating the passage from St. Matthew's Gospel.

Few residency training programmes explicitly require substantive exposure to issues in medical ethics and fewer still have a formal curriculum in this area. Traditional undergraduate medical ethics courses teach preclinical students to identify ethical issues and analyse them at a theoretical level. Residency training, however, is the ideal time to establish the critical behavioural link which makes ethics truly useful in clinical medicine. The General Internal Medicine Residency Training Program at Rhode Island Hospital has developed an integrated, three-year curriculum with (...) the goals of helping residents to perceive ethical issues in clinical practice, to utilise basic philosophical principles in resolving ethical dilemmas and to communicate these issues clearly and sensitively to patients. The curriculum has been well received by residents and has had a hospital-wide impact. We believe that training residents in medical ethics and communication skills is an effective approach to developing physicians' humane qualities. (shrink)

Over the course of three decades, in works spanning questions of theory, technique, and clinical practice, Charles Brenner has emerged as one of the preeminent analysts of his generation, a thinker whose probing estimation of mental conflict has promoted the evolutionary growth of analysis as theory even as it has clarified the clinical import of analysis as therapy. In _Psychoanalysis: The Science of Mental Conflict_, distinguished theorists and clinicians pay homage to Brenner by presenting original essays that converge in their (...) estimation of analysis as "the science of mental conflict." In sections that encompass "The Theory of Psychoanalysis," "The Concepts of Psychoanalysis," "The Technique of Psychoanalysis," "The Clinical Practice of Psychoanalysis," "The Teaching of Psychoanalysis," and "The Application of Psychanalysis," the contributors show how the perspective of conflict - broadened and refined by the clinical findings of recent decades - offers a vehicle for creative theory-building and, as such, a conceptual handle for apprising the indications for, and action of, psychoanalytic therapy. Arnold Richards' comprehensive overview of Brenner's ranging contributions to theory and practice, along with Martin Willick's critical introductions to the various sections of the book, round out a collections whose scope is complimented by its unusual coherence and thematic unity. Taken together, the essays comprising this book present readers with a cogent summary of current psychoanalytic thinking, along with an exciting preview of where it is heading in the future. As such, this volume will be welcomed not only by analysts, but by all mental health professionals who draw on, and learn from, the psychoanalytic assessment of conflict in mental life. It is a work that follows Brenner's own example in promoting the critical understanding of a generation of theorists, clinicians, and educators. (shrink)

ABSTRACT:In a series of reports the United Nations Special Representative on the issue of Human Rights and Transnational Corporations has emphasized a tripartite framework regarding business and human rights that includes the state “duty to protect,” the TNC “responsibility to respect,” and “appropriate remedies” for human rights violations. This article examines the recent history of UN initiatives regarding business and human rights and places the tripartite framework in historical context. Three approaches to human rights are distinguished: moral, political, and legal. (...) It is argued that the tripartite framework’s grounding of the responsibility of TNCs to respect human rights is properly understood as moral and not merely as a political or legal duty. A moral account of the duty of TNCs to respect basic human rights is defended and contrasted with a merely strategic approach. The main conclusion of the article is that only a moral account of the basic human rights duties of TNCs provides a sufficiently deep justification of “the corporate responsibility to respect human rights” feature of the tripartite framework.

Background:Nurses must balance their perceived duty to care against their perceived risk of harm to determine their willingness to report during disaster events, potentially creating an ethical dilemma and impacting patient care.Research aim:The purpose of this study was to investigate nurses’ perceived duty to care and whether there were differences in willingness to respond during disaster events based on perceived levels of duty to care.Research design:A cross-sectional survey research design was used in this study.Participants and research context:Using a convenience sample (...) with a snowball technique, data were collected from 289 nurses throughout the United States in 2017. Participants were recruited through host university websites, Facebook, and an American Nurses Association discussion board.Ethical considerations:Institutional review board approval was obtained from the University of Texas at Tyler and the University of Arkansas.Findings:Analysis of willingness to report to work based on levels of perceived duty to care resulted in the emergence of two groups: “lower level of perceived duty to care group” and “higher level of perceived duty to care group.” The most discriminating characteristics differentiating the groups included fear of abandonment by co-workers, reporting because it is morally the right thing to, and because of imperatives within the Nursing Code of Ethics.Discussion:The number of nurses in the lower level of perceived duty to care group causes concern. It is important for nursing management to develop strategies to advance nurses’ safety, minimize nurses’ risk, and promote nurses’ knowledge to confidently work during disaster situations.Conclusion:Level of perceived duty to care affects nurses’ willingness to report to work during disasters. Primary indicators of low perceived duty to care are amenable to actionable strategies, potentially increasing nurses’ perceived duty to provide care and willingness to report to work during disasters.

In _Buddhists, Brahmins, and Belief_, Dan Arnold examines how the Brahmanical tradition of Purva Mimamsa and the writings of the seventh-century Buddhist Madhyamika philosopher Candrakirti challenged dominant Indian Buddhist views of epistemology. Arnold retrieves these two very different but equally important voices of philosophical dissent, showing them to have developed highly sophisticated and cogent critiques of influential Buddhist epistemologists such as Dignaga and Dharmakirti. His analysis--developed in conversation with modern Western philosophers like William Alston and J. L. Austin--offers (...) an innovative reinterpretation of the Indian philosophical tradition, while suggesting that pre-modern Indian thinkers have much to contribute to contemporary philosophical debates. In logically distinct ways, Purva Mimamsa and Candrakirti's Madhyamaka opposed the influential Buddhist school of thought that emphasized the foundational character of perception. Arnold argues that Mimamsaka arguments concerning the "intrinsic validity" of the earliest Vedic scriptures are best understood as a critique of the tradition of Buddhist philosophy stemming from Dignaga. Though often dismissed as antithetical to "real philosophy," Mimamsaka thought has affinities with the reformed epistemology that has recently influenced contemporary philosophy of religion. Candrakirti's arguments, in contrast, amount to a principled refusal of epistemology. Arnold contends that Candrakirti marshals against Buddhist foundationalism an approach that resembles twentieth-century ordinary language philosophy--and does so by employing what are finally best understood as transcendental arguments. The conclusion that Candrakirti's arguments thus support a metaphysical claim represents a bold new understanding of Madhyamaka. (shrink)

As a way to address both ominous and ordinary threats of artificial intelligence, researchers have started proposing ways to stop an AI system before it has a chance to escape outside control and cause harm. A so-called “big red button” would enable human operators to interrupt or divert a system while preventing the system from learning that such an intervention is a threat. Though an emergency button for AI seems to make intuitive sense, that approach ultimately concentrates on the point (...) when a system has already “gone rogue” and seeks to obstruct interference. A better approach would be to make ongoing self-evaluation and testing an integral part of a system’s operation, diagnose how the system is in error and to prevent chaos and risk before they start. In this paper, we describe the demands that recent big red button proposals have not addressed, and we offer a preliminary model of an approach that could better meet them. We argue for an ethical core that consists of a scenario-generation mechanism and a simulation environment that are used to test a system’s decisions in simulated worlds, rather than the real world. This EC would be kept opaque to the system itself: through careful design of memory and the character of the scenario, the system’s algorithms would be prevented from learning about its operation and its function, and ultimately its presence. By monitoring and checking for deviant behavior, we conclude, a continual testing approach will be far more effective, responsive, and vigilant toward a system’s learning and action in the world than an emergency button which one might not get to push in time.

Premodern Buddhists are sometimes characterized as veritable "mind scientists" whose insights anticipate modern research on the brain and mind. Aiming to complicate this story, Dan Arnold confronts a significant obstacle to popular attempts at harmonizing classical Buddhist and modern scientific thought: since most Indian Buddhists held that the mental continuum is uninterrupted by death, they would have no truck with the idea that everything about the mental can be explained in terms of brain events. Nevertheless, a predominant stream of (...) Indian Buddhist thought, associated with the seventh-century thinker Dharmakirti, turns out to be vulnerable to arguments modern philosophers have leveled against physicalism. By characterizing the philosophical problems commonly faced by Dharmakirti and contemporary philosophers such as Jerry Fodor and Daniel Dennett, Arnold seeks to advance an understanding of both first-millennium Indian arguments and contemporary debates on the philosophy of mind. The issues center on what modern philosophers have called _intentionality_--the fact that the mind can be about other things. Tracing an account of intentionality through Kant, Wilfrid Sellars, and John McDowell, Arnold argues that intentionality cannot, in principle, be explained in causal terms. Elaborating some of Dharmakirti's central commitments, Arnold shows that despite his concern to refute physicalism, Dharmakirti's causal explanations of the mental mean that modern arguments from intentionality cut as much against his project as they do against physicalist philosophies of mind. This is evident in the arguments of some of Dharmakirti's contemporaneous Indian critics, whose critiques exemplify the same logic as modern arguments from intentionality. Elaborating these various strands of thought, Arnold shows that seemingly arcane arguments among first-millennium Indian thinkers can illuminate matters still very much at the heart of contemporary philosophy.

EDITORIAL NOTE.—Arnold Hauser died in February 1978 shortly after returning to his native Hungary; he had lived nearly half of his 85 years in a kind of self-imposed exile. He is considered, by those who know his work, to be perhaps the greatest sociologist of art, though his last years were spent in comparative neglect and obscurity. We present here as a testament to the importance of both the critic and the discipline he helped shape a section from the (...) translation of his Sociology of Art . Hauser's work draws on the influences of his teachers, Simmel, Bergson, Lukács, Mannheim, Sombart, and Troeltsch. He developed in his immense Social History of Art the groundwork for a sociological analysis of art ranging from prehistoric cave painting to film. In his later works—The Philosophy of Art History , Mannerism: The Crisis of the Renaissance and the Origins of Modern Art , and The Sociology of Art—he continued to redefine his brilliant defense of art for society's sake. The theory of l'art pour l'art wants nothing to do with this contradiction and denies not only the moral and social usefulness of art but its every possible practical function as well. "Nobody would write poetry," says Eugenio Montale, "if the problem of literature consisted in making oneself understood." It has been doubted whether the capacity of making oneself understood, the unambiguous communication of feelings and experiences, even lies within the power of art. What Eduardo Hanslick asserts about music in Von musikalischen Schönen, namely, that its relation to everything which is nonmusical, everything which has emotional content, is vague and noncommittal, is to some extent true for all arts. Just as music expresses something which cannot be translated into any other form, so literature expresses something which is eminently literary, linguistic, something locked into words and syntactic structures. In the same way the untranslatable content of a painting, a pictorial idea, a vision, can only be seized and held onto in optical forms. The composer thinks in tones, the painter in lines and colors, the poet in words, tropes, and rhythms. Indubitable as this is, it is not the whole truth; side by side with the content which can only be expressed adequately in a particular form, there is an intrinsic value which can be translated into any form. Kenneth Northcott, translator of this essay, is professor of older German literature and of comparative literature at the University of Chicago. He is currently engaged in the translation of The Sociology of Art and in the study of late medieval satire in Germany and the works of Harold Pinter, in whose plays he also delights to act. (shrink)
