An important application of cognitive architectures is to provide human performance models that capture psychological mechanisms in a form that can be “programmed” to predict task performance of human–machine system designs. Although many aspects of human performance have been successfully modeled in this approach, accounting for multitalker speech task performance is a novel problem. This article presents a model for performance in a two-talker task that incorporates concepts from psychoacoustics, in particular, masking effects and stream formation.

The question of whether lies by those who govern are acceptable receives a clear focus and an ideal case in the Republic. Against C. D. C. Reeve, and T. C. Brickhouse and N. D Smith, I argue that the Republic’s apparent recommendation of administrative lies is incoherent. While lies may be a necessary part of the City’s administration, the process and practice of lying undermines that nature which is necessary for any suitable ruler – rendering the ideal impossible. I argue (...) that this analysis, while concerned with an ideal case, also applies to the political realist’s regrettable-but-necessary defence of such practices. (shrink)

Can civic engagement rescue the humanities from a prolonged identity crisis? How can the practices and methods, the conventions and innovations of humanities teaching and scholarship yield knowledge that contributes to the public good? These are just two of the vexing questions David D. Cooper tackles in his essays on the humanities, literacy, and public life. As insightful as they are provocative, these essays address important issues head-on and raise questions about the relevance and roles of humanities teaching and (...) scholarship, the moral footings and public purposes of the humanities, engaged teaching practices, institutional and disciplinary reform, academic professionalism, and public scholarship in a democracy. Destined to stir discussion about the purposes of the humanities and the problems we face during an era of declining institutional support, public alienation and misunderstanding, student ambivalence, and diminishing resources, the questions Cooper raises in this book are uncomfortable and, in his view, necessary for reflection, renewal, and reform. With frank, deft assessments, Cooper reports on active learning initiatives that reenergized his own teaching life while reshaping the teaching mission of the humanities, including service learning, collaborative learning, the learning community movement, and student-centered and deliberative pedagogy.

Hannah Arendt's work inspires many to stand in solidarity against authoritarianism, racial or gender-based violence, climate change, and right-wing populism. But what if a careful analysis of her oeuvre reveals a darker side to this intellectual legacy? What if solidarity, as she conceives of it, is not oriented toward equality, freedom, or justice for all, but creates a barrier to intersectional coalition building? In Arendt's Solidarity, David D. Kim illuminates Arendt's lifelong struggle with this deceptively straightforward yet divisive concept. (...) Drawing upon her publications, unpublished documents, private letters, radio and television interviews, newspaper clippings, and archival marginalia, Kim examines how Arendt refutes solidarity as an effective political force against anti-Semitism, racial injustice, or social inequality. As Kim reveals, this conceptual conundrum follows the arc of Arendt's forced migration across the Atlantic and is directly related to every major concern of hers: Christian neighborly love, friendship, Jewish assimilation, Zionism, National Socialism, the American republic, Black Power, revolution, violence, and the human world. Kim places these thoughts in dialogue with dissenting voices, such as Thomas Mann, Gershom Scholem, Jean-Paul Sartre, James Baldwin, Frantz Fanon, James Forman, and Ralph Ellison. The result is a full-scale reinterpretation of Arendt's oeuvre. (shrink)

When The Absurd Hero in American Fiction was first released in 1966, Granville Hicks praised it in a lead article for the Saturday Review as a sensitive and definitive study of a new trend in postwar American literature. In the years that followed, David Galloway’s analysis of the writings of John Updike, William Styron, Saul Bellow, and J. D. Salinger became a standard critical work, an indispensable tool for readers concerned with contemporary American literature. The New York Times described (...) the book as “a seminal study of the modern literary imagination." David Galloway, himself an established novelist, later extensively revised The Absurd Hero to include authoritative discussions of more than a dozen novels which had appeared since the first revised edition was released in 1970. Among them are John Updike’s Couples, Rabbit Redux, and The Coup; William Styron’s The Confessions of Nat Turner and Sophie’s Choice; and Saul Bellow’s Mr. Sammler’s Planet and Humboldt’s Gift. Through detailed analyses of these works, Galloway demonstrates the continuing relevance of his own provocative concept of the absurd hero and provides important insights into the literary achievements of four of America’s most influential postwar novelists.

Political science faces a challenge from a “Mr. Perestroika,” who decries the hegemony of formal and statistical analysis in the discipline. Although not connected with this movement, Bent Flyvbjerg makes the best case for a renewed dominance for qualitative and case study work throughout the social sciences. This article challenges Flyvbjerg’s call for a phronetic as opposed to an epistemic discipline. It challenges as well the unqualified call for pluralism advocated by many in the perestroika movement. It offers instead an (...) integrated tripartite method in which narrative, statistics, and formal modeling fill in a scientific frame. (shrink)

Here I discuss findings that suggest a universal mechanism for proteins (and RNA) to recognize and interact with various binding partners by selectively binding to different conformations that pre‐exist in the free protein's conformational ensemble. The tandem RNA recognition motif domains of splicing factor U2AF65 fluctuate in solution between a predominately closed conformation in which the RNA binding site of one of the domains is blocked, and a lowly populated open conformation in which both RNA binding pockets are accessible. RNA (...) binding to U2AF65 may thus occur through the weakly populated open conformation, and the binding interaction stabilizes the open conformation. The conformational diversity observed in U2AF65 might also facilitate binding to diverse RNA sequences as found in the polypyrimidine tracts that help define 3′ splice sites. Similar binding pathways in other systems have important consequences in biological regulation, molecular evolution, and information storage. (shrink)

Physicians and other healthcare professionals are increasingly finding ways to use artificial intelligent decision support systems in their work. IBM Watson Health, for example, is a commercially available technology that is providing AI-DDS services in genomics, oncology, healthcare management and more.1 AI’s ability to scan massive amounts of data, detect patterns, and derive solutions from data is vastly more superior than that of humans. AI technology is undeniably integral to the future of healthcare and public health, and thoughtful consideration of (...) the legal, ethical and moral issues surrounding this technology is a must. The authors of the article, Responsibility, Second Opinions, and Peer-Disagreement—Ethical and Epistemological Challenges of Using AI in Clinical Diagnostic Contexts, provide an informed discussion of how AI-DSS may be used, both practically and ethically, to assist healthcare professionals in cooperative diagnostic processes2. The authors propose a process, whereby AI-DSS would provide a physician a second opinion, and when there is a mismatch between opinions, another physician would provide a third opinion. This approach maintains a ‘physician-in-charge’ perspective, and suggests that decision-making must ultimately be made by a person. This approach is also consistent with the ‘physician in-the-loop’ concept, such that even when increasingly autonomous AI-DSSs are put to use, physicians will still be providing checks and overseeing clinical decisions. The authors conceptualise AI as a replacement of human cognitive labour. That is, AI is used to supplant a human professional in particular functions …. (shrink)

When considering submissions ethics committees should be consistent in all aspects of their review. A wide variation in performance is likely to result in the unfair dismissal of good research on the one hand with inadequate ethical review on the other, neither of which is acceptable. The recent annual reports for UK MRECs suggest that the level of unfavourable opinion ranges from 6.9% to 24.2% Although a certain level of inconsistency is inherent in the system of ethical review there is (...) little research to determine how much of that inconsistency in inevitable and how much of it is the result of poor process. The time has come for high quality research to be done to assess the consistency and hence the validity of ethical review. (shrink)

An alternative approach to emotion is presented here, which differs from that of Kagan and others. It orders emotion along a continuum of the embodiment of emotion, starting with a clear but rare case of pure emotion and at the other extreme discusses Damasio’s intelligent prefrontal patients who could not feel emotions critical to social life.

Ensuring that research is of high quality and is based on sound ethical principles is not easy; it requires a fine balance between adequate oversight and suitable facilitation. The current state of research ethics governance is an ideal environment to maintain a governance ‘ratchet’ rather than produce a well-organized and carefully thought out ‘dial’.

The history of the book is everywhere, so widely diffused that it merits comparison with the famously elusive Scarlet Pimpernel, whose pursuers sought him without success. Like that figure, book history passes among us in disguise, reluctant to reveal its presence even as it gains ever-greater recognition. In some quarters, it lurks within the domain of bibliography, a field of scholarship dedicated to describing the histories of printed texts and, in the service of this enterprise, concerned with the details of (...) book-making. Elsewhere, book history installs itself within descriptions of libraries and education, sharing, with the first of these, a concern for how old books were accumulated and classified and, with the second, for the many ramifications of literacy and the fashioning of schoolbooks. Together with the history of journalism it studies how news was disseminated and ponders the significance of periodicals, be these newspapers or magazines. Political history has been another convenient site of disguise in the wake of efforts to connect the public sphere and concepts of nation with the emergence of print culture. And, of course, book history has enjoyed a long and fruitful kinship with literary history, a relationship freshly energized in recent decades as literary historians turned to describing the rise and remaking of a canon and to emphasizing the mediations that all texts undergosociology of texts,” to borrow a phrase made famous by D. F. McKenzie. To this list we can add the version of intellectual history that reconstructs the reading of a person or group and employs this data to generalize about the coming of the Enlightenment and similar formations.

A fascinating collection of revealing memoirs by sixty-four philosophers discussing how they fell in love with philosophy, their calling to this life in pursuit of wisdom, and how they eventually or suddenly became philosophers.

As the latest tool for disseminated information and editorial comment shaping public opinion, blogging is quickly gaining popularity, prominence, and power. One major controversy for the new medium of circulating news and commentary is to what extent or even whether blogs should have codes of ethics. We examined 30 politically-oriented weblogs. Of these, only a few had a code of ethics, stated or implied. Little cohesion existed between the codes of ethics, but a few themes emerged. Qualitative analysis of the (...) codes of ethics shows that what bloggers valued most included accuracy, credibility, and etiquette. We further provide evidence to support the prevailing thought that, while appearing to be "ethical" seems important to bloggers, blogging ethics and credibility are difficult to operationalize.

"An admirable accomplishment.... Roberts provides valuable insights into the current debate on the nature of historical knowledge in our present 'postmodern' time. Anyone concerned with the philosophy of history will need to reckon with this book."--Allan D. Megill, author of "Prophets of Extremity".

Informed consent is crucial in most research but written consent is not without its drawbacks. Written consent serves to protect the researcher more than it serves to protect the participant and this can present a barrier to their relationship. In certain circumstances it can undermine the trust important in research. For ‘simple’ studies, where treatments are largely interchangeable or where consent is implied, written consent can be considered not only to be unnecessary, but actually harmful. Research ethics committees should consider (...) removing the requirement for written consent in these studies. (shrink)

ABSTRACT In The Longing for Total Revolution, Bernard Yack claims not to account for totalitarianism but simply to unearth a new, specifically modern mindset. Still, the problem of totalitarianism, and whatever connection it might have had with that mindset, lurks throughout his book. Yack convincingly posits a relationship between a troubling new sense of historical embeddedness and novel totalist thinking. But his sense of the range of responses to historicity proves too limited to illuminate the connection between the longing for (...) total revolution and the advent of totalitarianism. Another look at Yack’s two culminating figures, Marx and Nietzsche, suggests a more illuminating alternative. (shrink)

Despite suggestions that the end of metaphysics leaves us with nothing but history, essential questions about the place of history in a post-metaphysical culture have been neglected. In one sense history "weakens" as the scope for "realism" or a teleological master narrative fall away. But it invites overreaction to suggest that history becomes a "process of weakening" insofar as things have come to be as they are not as the resultants of full, meaningful origins, but only through the "dread accident" (...) of the historical process. The world that has resulted from history is the only one we have, and it weighs on us; in that sense history does not weaken but strengthens. Still, the historical process enveloping us is not Hegelian and necessary but weak and contingent, its outcomes subject to further contest. Conversely, although truth is weak, finite, and provisional, it is not merely consensual or relative precisely because it is historical. To grasp the sense it which history both weakens and strengthens enables us to grasp the scope for learning more deeply from our historical experience. A fuller range of historical questions about modernity would enable us better to understand the ongoing dangers and possibilities of modern politics. (shrink)

For a patient to make an informed decision about participation in research, it is fundamental that they can understand what is involved. COREC has produced a model information sheet and consent form that researchers are encouraged and sometimes forced to use by LRECs. By applying readability statistics to these documents we have shown that the majority of the UK population would not be able to read this proposed text.
