Depuis une vingtaine d'années, l'oeuvre de C. E. Shannon semble être l'objet d'un relatif oubli dans l'ensemble disciplinaire nommé en France « Sciences de l'information et de la communication ». Cet article essaie d'en saisir les raisons, après en avoir rappelé le succès. Il plaide pour une relecture épistémologique du fameux schéma de la mesure d'information de Shannon. C'est ainsi que le « nombre de bits », terme à peu près incompréhensible du côté des sciences humaines, peut se (...) voir donner un sens et être appréhendé comme le nombre de questions pour identifier un objet. Ceci permet alors de considérer que l'élaboration shannonienne pourrait constituer un matériau fondamental pour la cyberculture, entendue comme réflexion sur notre rapport informationnel au monde physique et social.For twenty years, the work of CE Shannon seems to be the subject of a relatively neglected in all disciplinary named in France "Information Science and Communication." This article tries to understand the reasons, after having recalled the success. He argues for a reinterpretation of the famous epistemological schema information measure of Shannon. Thus the "number of bits", a term almost incomprehensible side humanities, can be given a meaning and be understood as the number of questions to identify an object. This then allows to consider the development shannonienne could be a fundamental material for cyberculture, understood as a reflection of our informational report to physical and social world.

This study concerns the role of reflective judgment in both aesthetical appreciation and one’s self-understanding in relation to an unfamiliar other. Pillow’s thesis is that “Sublime reflection can provide … a model for a kind of interpretive response to the uncanny Other ‘outside’ our conceptual grasp. It thereby advances our sense-making pursuits even while eschewing unified, conceptual determination”. His principal focus is on Kant’s development of sublime judgment in the third Critique, where this form of reflective judgment becomes central to (...) Pillow’s greater theme: “I privilege sublime reflection in particular because it best models our interpretative search for meanings in things … furthermore, this reflection acknowledges the constitutive limitations of context-dependent understanding, its incapacity to determine fully the sense-making wholes it reaches to comprehend”. Hegel is drawn into the study ostensibly for two reasons. First, he has a more extensive, and determinate, idea of the content of aesthetical appreciation, whereas Kant adheres to a formalistic notion; second, Hegel is the foil for Pillow’s postmodern approach to the significance of reflective understanding. Since Hegel’s Aesthetics presents “the content of an art work … [in] a single fixed theme wholly available to conceptual analysis,” it stands opposed to Pillow’s view that the relation between the self-understanding subject and the other must remain “open” and foreign. Between and above Kant and Hegel floats Lyotard whose deconstructionist work on practical reason forms the impetus in Pillow’s study. (shrink)
Warrior cultures throughout history have developed unique codes that restrict their behavior and set them apart from the rest of society. But what possible reason could a warrior have for accepting such restraints? Why should those whose profession can force them into hellish kill-or-be-killed conditions care about such lofty concepts as honor, courage, nobility, duty, and sacrifice? And why should it matter so much to the warriors themselves that they be something more than mere murderers? The Code of the Warrior (...) tackles these timely issues and takes the reader on a tour of warrior cultures and their values, from the ancient Greeks and Romans to the 'barbaric' Vikings and Celts, from legendary chivalric knights to Native American tribesmen, from Chinese warrior monks pursuing enlightenment to Japanese samurai practicing death. Drawing these rich traditions up to the present, the author quests for a code for the warriors of today, as they do battle in asymmetric conflicts against unconventional forces and the scourge of global terrorism.

After decades of single issue movements and identity politics on the U.S. left, the series of large demonstrations beginning in 1999 in Seattle have led many to wonder if activist politics can now come together around a common theme of global justice. This book pursues the prospects for progressive political movements in the 21st century with case studies of ten representative movements, including the anti-globalization forces, environmental interest groups, and new takes on the peace movement.
Symbolic arithmetic is fundamental to science, technology and economics, but its acquisition by children typically requires years of effort, instruction and drill1,2. When adults perform mental arithmetic, they activate nonsymbolic, approximate number representations3,4, and their performance suffers if this nonsymbolic system is impaired5. Nonsymbolic number representations also allow adults, children, and even infants to add or subtract pairs of dot arrays and to compare the resulting sum or difference to a third array, provided that only approximate accuracy is required6–10. Here (...) we report that young children, who have mastered verbal counting and are on the threshold of arithmetic instruction, can build on their nonsymbolic number system to perform symbolic addition and subtraction11–15. Children across a broad socio-economic spectrum solved symbolic problems involving approximate addition or subtraction of large numbers, both in a laboratory test and in a school setting. Aspects of symbolic arithmetic therefore lie within the reach of children who have learned no algorithms for manipulating numerical symbols. Our findings help to delimit the sources of children’s difficulties learning symbolic arithmetic, and they suggest ways to enhance children’s engagement with formal mathematics. We presented children with approximate symbolic arithmetic problems in a format that parallels previous tests of non-symbolic arithmetic in preschool children8,9. In the first experiment, five- to six-year-old children were given problems such as ‘‘If you had twenty-four stickers and I gave you twenty-seven more, would you have more or less than thirty-five stickers?’’. Children performed well above chance (65.0%, t1952.77, P 5 0.012) without resorting to guessing or comparison strategies that could serve as alternatives to arithmetic. Children who have been taught no symbolic arithmetic therefore have some ability to perform symbolic addition problems. The children’s performance nevertheless fell short of performance on non-symbolic arithmetic tasks using equivalent addition problems with numbers presented as arrays of dots and with the addition operation conveyed by successive motions of the dots into a box (71.3% correct, F1,345 4.26, P 5 0.047)8..

The inconclusiveness of previous research on the association between gender diverse boards and corporate social performance has led us to revisit the question in light of stakeholder management and institutional theories. Given that corporate social responsibility is a multidimensional concept, we test the influence of GDB on various groups of stakeholders. By considering the interaction between stakeholders’ power and directors’ personal motivations toward the prioritization of stakeholders’ claims, we find that GDB are positively related to CSR dimensions that are related (...) to less powerful stakeholders such as the environment, contractors, and the community. However, GDB do not appear to have a significant impact on CSR dimensions that are associated with stakeholders who benefit from more institutionalized power, such as employees and customers.

Examined as an isolated situation, and through the lens of a rare and feared disease, Mr. Duncan's case seems ripe for second-guessing the physicians and nurses who cared for him. But viewed from the perspective of what we know about errors and team communication, his case is all too common. Nearly 440,000 patient deaths in the U.S. each year may be attributable to medical errors. Breakdowns in communication among health care teams contribute in the majority of these errors. The culture (...) of health care does not seem to foster functional, effective communication between and among professionals. Why? And more importantly, why do we not do something about it? (shrink)
Drawing on philosophy, history, moral psychology, and ethics, this revised and expanded edition of French’s The Code of the Warrior examines historical and contemporary warrior cultures and their values, arguing that today’s warriors need a code, as their ancestors did, to prevent them from crossing the thin but critical line that separates warriors from murderers in the battle against global terrorism.
How is a disease contracted, and how does it progress through the body? Answers to these questions are fundamental to understanding both basic biology and medicine. Advances in the biomedical sciences continue to provide more tools to address these fundamental questions and to uncover questions that have not been thought of before. Despite these major advances, we are still facing conceptual and technical challenges when learning about the etiology of disease, especially for genetic diseases. In this review, we illustrate this (...) point by discussing the causal links between molecular mechanisms and systems-level phenotypes in molecular diseases. We begin with an examination of sickle cell anemia, and how mechanisms of the disease have been comprehended over the last century. While sickle cell anemia involves a mutation in a single protein in a single cell type, other diseases involve mutations in networks with many protein interactions and in diverse cell types. We introduce the challenges that result from these differences and illustrate the current obstacles by discussing the RASopathies, a recently discovered class of developmental syndromes that result from mutations in signaling networks. Methods to study mutant genotypes that lead to mutant phenotypes are discussed, particularly the use of model organisms and mutant proteins to study protein interactions that may be important for development of disease. These studies will point toward the future of diagnosing and treating genetic disease. (shrink)
Disciplinary boundaries become increasingly unclear when grappling with “wicked problems,” which present a complex set of policy, cultural, technological, and scientific dimensions. “T-shaped” professionals, i.e. individuals with a depth and breadth of expertise, are being called upon to play a critical role in complex problem-solving. This paper unpacks the notion of the “T-shaped expert” and seeks to situate it within the broader academic literature on expertise, integration, and developmental learning. A component of this project includes an exploratory study, which is (...) aimed at evaluating the emergent attributes of T-shaped expertise in two different educational programs completed between January and May in 2015. The two programs build disciplinary knowledge in science, technology engineering, and mathematics fields at the core, while expanding the students’ awareness and comprehension of other expertise. The courses introduced science and engineering students to case study topics focusing around complex human-technological-ecological systems in a nanotechnology and society course; and the governance of genetically modified organisms in a science, technology, and society course. We analyze pre- and post-test data from this pilot project before presenting findings that pertain to student learning, as well as variants in the methodology and reflect on the utility of the selected methodology for evaluating expertise as it evolves over time. The paper closes with a discussion of a theory of acquisition with implications for delineating early attributes and characteristics of T-shaped expertise. (shrink)
The following study departs from the lecture, entitled “Creative thinking”, delivered by ClaudeShannon in 1952 at the Bell Laboratories. This paper includes an interpretive and critical account of the necessary conditions, as well as the desirable procedures, which must be satisfied in the scientific and technological invention, within the frame of the so-called scientist’s spontaneous philosophy.
