In human groups performing oscillatory tasks, it has been observed that the frequency of participants' oscillations reduces when compared to that acquired in solo. This experimental observation is not captured by the standard Kuramoto oscillators, often employed to model human synchronization. In this work, we aim at capturing this observed phenomenon by proposing three alternative modifications of the standard Kuramoto model that are based on three different biologically-relevant hypotheses underlying group synchronization. The three models are tuned, validated and compared against (...) experiments on a group synchronization task, which is a multi-agent extension of the so-called mirror game. (shrink)

This paper uses a non-distributive system of Boolean fractions (a|b), where a and b are 2-valued propositions or events, to express uncertain conditional propositions and conditional events. These Boolean fractions, 'a if b' or 'a given b', ordered pairs of events, which did not exist for the founders of quantum logic, can better represent uncertain conditional information just as integer fractions can better represent partial distances on a number line. Since the indeterminacy of some pairs of quantum events is due (...) to the mutual inconsistency of their experimental conditions, this algebra of conditionals can express indeterminacy. In fact, this system is able to express the crucial quantum concepts of orthogonality, simultaneous verifiability, compatibility, and the superposition of quantum events, all without resorting to Hilbert space. A conditional (a|b) is said to be "inapplicable" (or "undefined") in those instances or models for which b is false. Otherwise the conditional takes the truth-value of proposition a. Thus the system is technically 3-valued, but the 3rd value has nothing to do with a state of ignorance, nor to some half-truth. People already routinely put statements into three categories: true, false, or inapplicable. As such, this system applies to macroscopic as well as microscopic events. Two conditional propositions turn out to be simultaneously verifiable just in case the truth of one implies the applicability of the other. Furthermore, two conditional propositions (a|b) and (c|d) reside in a common Boolean sub-algebra of the non-distributive system of conditional propositions just in case b = d, their conditions are equivalent. Since all aspects of quantum mechanics can be represented with this near classical logic, there is no need to adopt Hilbert space logic as ordinary logic, just a need perhaps to adopt propositional fractions to do logic, just as we long ago adopted integer fractions to do arithmetic. The algebra of Boolean fractions is a natural, near-Boolean extension of Boolean algebra adequate to express quantum logic. While this paper explains one group of quantum anomalies, it nevertheless leaves no less mysterious the 'influence-at-a-distance', quantum entanglement phenomena. A quantum realist must still embrace non-local influences to hold that "hidden variables" are the measured properties of particles. But that seems easier than imaging wave-particle duality and instant collapse, as offered by proponents of the standard interpretation of quantum mechanics. (shrink)

In a recent paper in Science and Engineering Ethics (SEE) Elliott proposed an ethics of expertise, providing its theoretical foundation along with its application in a case study devoted to the topic of hormesis. The application is based on a commentary in the journal Nature, and it includes assertions of ethical breaches. Elliott concludes that the authors of the commentary failed to promote the informed consent of decision makers by not providing representative information about alternative frequency estimates of hormesis in (...) the literature, thereby hindering the capacity of the scientific community to promote informed consent relating to chemical regulation. This paper argues that Elliott should have incorporated due process into his system of evaluation. His argument is also seriously deficient technically, in that it misinterprets the toxicological issues, misrepresents the scientific literature with respect to the frequency of hormesis, and incorrectly assesses the extent to which the Nature paper revealed opposing/alternative views on hormesis. Given the seriousness of assertions of noncompliance to ethical norms, there must be procedures to protect those whose ethics were called into question, to fairly evaluate the technical justification for an assertion, and to enable corrections in the event of errors. If a journal is willing to publish assertions that individuals acted in an ethically questionable way, it should be guided by a documented code of ethics and meet a standard of responsibility far greater than normal peer-review processes for papers that do not entail such ethical judgments.

The work of Sophocles shows the human suffering which might be caused by evil without the presence of guilt. Within the historic confrontation of the Athenian political stage, the presentation of the tragic conflict opposes the illustrated omnipotence: to present that what is divine as incomprehensible is one of the traditional features of Sophocles’ work and his announcement of anti-modernity. “Not-understanding” is the banner of silence when faced with the limit of natural reason. As a response to sophist thought, which (...) replaced the divine paradigm, the preponderance of the gods in the work of Sophocles might be seen as an affirmation. What is characteristic of the traditional restoration proposed by Sophocles is not only the appearance of the Gods in his works, but the particular way in which they reveal themselves. Knowing that what is divine is not characteristic of men because it is not a feature of the former to be understood to a lesser degree than that of its own nature. That is exactly the stage where the struggle between the reality of knowing and the relative appearance of knowing occurs. Bearing this interpretative intention in mind, the aim of the paper is to highlight the way in which evil reveals itself in Oedipus the King, as a device chosen by the gods to trigger the unfolding of the nature of the hero.

To study the interaction of forces that produce chest wall motion, we propose a model based on the lever system of Hillman and Finucane :951–961, 1987) and introduce some dynamic properties of the respiratory system. The passive elements are considered as elastic compartments linked to the open air via a resistive tube, an image of airways. The respiratory muscles force is applied to both compartments. Parameters of the model are identified in using experimental data of airflow signal measured by pneumotachography (...) and rib cage and abdomen signals measured by respiratory inductive plethysmography on eleven healthy volunteers in five conditions: at rest and with four level of added loads. A breath by breath analysis showed, whatever the individual and the condition are, that there are several breaths on which the airflow simulated by our model is well fitted to the airflow measured by pneumotachography as estimated by a determination coefficient R2 ≥ 0.70. This very simple model may well represent the behaviour of the chest wall and thus may be useful to interpret the relative motion of rib cage and abdomen during quiet breathing. (shrink)

In recent decades, psychological research on the effects of mindfulness-based interventions has greatly developed and demonstrated a range of beneficial outcomes in a variety of populations and contexts. Yet, the question of how to foster subjective well-being and happiness remains open. Here, we assessed the effectiveness of an integrated mental training program The Art of Happiness on psychological well-being in a general population. The mental training program was designed to help practitioners develop new ways to nurture their own happiness. This (...) was achieved by seven modules aimed at cultivating positive cognition strategies and behaviors using both formal and informal practices. The program was conducted over a period of 9 months, also comprising two retreats, one in the middle and one at the end of the course. By using a set of established psychometric tools, we assessed the effects of such a mental training program on several psychological well-being dimensions, taking into account both the longitudinal effects of the course and the short-term effects arising from the intensive retreat experiences. The results showed that several psychological well-being measures gradually increased within participants from the beginning to the end of the course. This was especially true for life satisfaction, self-awareness, and emotional regulation, highlighting both short-term and longitudinal effects of the program. In conclusion, these findings suggest the potential of the mental training program, such as The Art of Happiness, for psychological well-being. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rhetoric, Hermeneutics, and Translation in the Middle AgesMichael CalabreseRhetoric, Hermeneutics, and Translation in the Middle Ages, by Rita Copeland; xiv & 295 pp. Cambridge: Cambridge University Press, 1991, $64.95 cloth, $22.95 paper.In this deeply learned book, Rita Copeland studies the history of rhetoric and grammar and their shifting roles in the history of translation, commentary, and interpretation from classical antiquity through the Middle Ages. Copeland examines the ideological (...) nexus of history, authority, and power in which commentary and vernacular translation function. “Vernacular writing,” she says, can “authorize itself by taking over the function of academic discourse” (p. 8). Her book then traces the history of this “authorization” and this “dis-placement” of Latin sources by the increasingly academically privileged vernacular. All in all, Copeland tells the story of how medieval literary culture articulated its translatio studii by confronting and preserving its Classical inheritance and also developing a role for the vernacular as an active, creative agent in the production of authoritative works. [End Page 413]Ultimately “rhetoric” is the star of Copeland’s book, and in essence she is telling its Roman and medieval life stories. By “rhetoric” we are to understand critical academic language that points toward ethics and practical action. Throughout the Middle Ages every modification or appropriation of critical tools expands the role of commentary and adds new forms of interpretive invention to the translation process. As Copeland puts it, “The medieval practice of translation as a form of appropriation and substitution will be conditioned, as in Roman contexts, by rhetorical theories of invention” (p. 36).The hermeneutical costar is grammar, for as part of the complex appropriation of classical practice, medieval readers recoup the “debased” Roman category of grammar, so that by the time of Martianus Capella it can “claim for itself the whole compass of literary activity” (p. 56). As grammar expands its power, so does rhetoric, a civic Roman art which gets “revalued in terms of service to theology” (p. 59). Medieval commentary now “assumes the character of rhetorical performance” (p. 86) and takes on a “primary productive character,” as it “continually refashions the [studied] text for changing conditions of understanding” (p. 64). What is emerging from all these developments is a medieval translation theory—and practice—which is informed by both academic and practical, ethical goals, that is, a hermeneutics forged by the link of grammar and rhetoric.The rest of the book studies the shifting status and the evolving role of the vernacular in this medieval hermeneutical drama. Copeland addresses the Ovide moralisé and the French translations of the Consolatio, and then Chaucer’s Legend of Good Women and Gower’s Confessio Amantis. We witness here how vernacular products take on authority by “inventing themselves” through authoritative discourse. In Gower’s Confessio we see the fusion of hermeneutics and rhetoric; the poem uses academic modes of discourse in the service of ethics or action. We thus see that by the late Middle Ages vernacular literature plays an authoritative role in the medieval translatio studii, as Gower seeks to “open the institution of learning to the widest possible audience and thereby empower it as a persuasive tool, leading to knowledge of the good” (p. 220). Overall, Copeland has told the story of the “leveling” of academic and vernacular discourse, so that the later, while not dispelling or overthrowing the former, can claim access to its traditional authority.Copeland’s prose is Latinate, at times pedantic and, at times, just plain Latin; reading the book can be a wearing experience. But it is all part of a history she knows in remarkable detail, a history that lies behind many assumptions we have about medieval ethical poetics. To have presented this history is a major scholarly feat. Copeland allows us to see medieval authors as both products and producers of methods of appropriation, imitation, conquest, and preservation—all strategies for “translating” the past and creating a present that can leave its intellectual mark on the future. One might now want to employ Copeland’s history of classical and medieval hermeneutics as a tool for [End Page 414] examining our own, contemporary academic rhetorics and for analyzing the “state of...

This paper assesses possible reasons why Hermann J. Muller avoided peer-review of data that became the basis of his Nobel Prize award for producing gene mutations in male Drosophila by X-rays. Extensive correspondence between Muller and close associates and other materials were obtained from preserved papers to compliment extensive publications by and about Muller in the open literature. These were evaluated for potential historical insights that clarify why he avoided peer-review of his Nobel Prize findings. This paper clarifies the basis (...) of Muller’s (Muller HJ, Sci 66 84-87, 1927c) belief that he produced X-ray induced “gene” mutations in Drosophila. It then shows his belief was contemporaneously challenged by his longtime friend/confidant and Drosophila geneticist, Edgar Altenburg. Altenburg insisted that Muller may have simply poked large holes in chromosomes with massive doses of X-rays, and needed to provide proof of gene “point” mutations. Given the daunting and uncertain task to experimentally address this criticism, especially within the context of trying to become first to produce gene mutations, it is proposed that Muller purposely avoided peer-review while rushing to publish his paper in Science to claim discovery primacy without showing any data. The present paper also explores ethical issues surrounding these actions, including those of the editor of Science, James McKeen Catell and Altenburg, and their subsequent impact on the scientific and regulatory communities. This historical analysis suggests that Muller deliberately avoided peer-review on his most significant findings because he was extremely troubled by the insightful and serious criticism of Altenburg, which suggested he had not produced gene mutations as he claimed. Nonetheless, Muller manipulated this situation (i.e., publishing a discussion within Science with no data, publishing a poorly written non-peer reviewed conference proceedings with no methods and materials, and no references) due to both the widespread euphoria over his claim of gene mutation and confidence that Altenburg would not publically challenge him. This situation permitted Muller to achieve his goal to be the first to produce gene mutations while buying him time to later try to experimentally address Altenburg’s criticisms, and a possible way to avoid discovery of his questionable actions.

Resumen Este artículo estudia la transformación de las bases del escepticismo antiguo en el pensamiento agustiniano; para presentar el proceso se parte de la crisis que supuso la ruptura con experiencia maniquea, se distingue su preocupación y consideración sobre el modo y los límites del conocimiento y se analiza la función de la imagen mítica de Proteo en Contra Académicos; esta imagen permite ponderar la capacidad de la representación mítica como contrafuerte del carácter discursivo del saber humano. Mediante este recurso, (...) san Agustín afirma que la razón no puede quedar aislada de otros modos complementarios de comprensión, hace propio el núcleo de la actitud escéptica y amplía la noción de racionalidad para la filosofía cristiana.This paper studies the transformation of the foundations of ancient skepticism in Augustinian thought; to present the process we start from the crisis that led to the break with Manichaean experience, we distinguished their concern and consideration about the mode and limits of knowledge and analyzed the function of Proteo's mythical image in Contra academicos; this image allows us to weigh the capacity of mythical representation as a buttress of the discursive character of human knowledge. Through this resource, St. Augustine affirms that reason cannot be isolated from other complementary modes of understanding, appropriates the core of the skeptical attitude and broadens the notion of rationality for Christian philosophy.

A leading young Italian semiologist scrutinizes today's cultural phenomena and finds the prevailing taste to be "neo-baroque"--characterized by an appetite for virtuosity, frantic rhythms, instability, poly-dimensionality, and change. Omar Calabrese locates a "sign of the times" in an amazing variety of literary, philosophical, artistic, musical, and architectural forms, from the Venice Biennale through the "new science" to television series, video games, and "zapping" with the remote control device from channel to channel! Calabrese admits that he begins the book (...) with a refusal to distinguish between "Donald Duck and Dante." Avoiding hierarchies or ghettos among works, he takes his readers on a fast-paced expedition through contemporary culture that closes with an elegant essay on evaluation and classical form. According to Calabrese, the enormous quantity of narrative now being produced has led to a new situation: everything has already been said, and everything has already been written. The only way of avoiding saturation has been to turn to a poetics of repetition. The author shows that pleasure in texts is now produced by tiny variations, and a certain kind of citation from other works has taken on a central importance that would have been unthinkable only a few years ago. In describing this development, and others shared by both avant-garde and mass media, he makes us aware of the rapid shrinkage in the once ample space between "highbrow" and "lowbrow." Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

La reflexión de Friederich Schleiermacher sobre la universidad se centra en las dificultades que observa para superar el estancamiento de la educación alemana a principios del siglo XIX y establece, en ella, dos niveles: por un lado, la excesiva burocratización de la vida universitaria, que le quita lo que tiene precisamente de vital y, por otro, desde la perspectiva propiamente del profesor, la imposibilidad de cultivar el talento de los alumnos mediante clases farragosas, en las que se repite lo que (...) ya está escrito y en las que la memoria es la única medida del conocimiento. La mayoría de los profesores se encuentran en esta situación porque los conocimientos se perciben de manera fragmentaria y, por lo tanto, se transmiten sin el contenido de su unidad profunda. La Facultad de Filosofía tiene el cometido de construir el camino hacia la unidad de conocimiento y fundamentar el sentido profundo de la vida universitaria. Por ello, los cimientos de la universidad moderna descansan sobre el profesor que investiga y transmite en sus clases el pathos de aquella tarea; también descansan sobre el alumno, a quien hay que ayudar a comprender la dimensión de su talento y desde allí, emprender la tarea de la auto-educación.

In this analysis of St. Augustine’s concept of natural law, the focus will be on the way he presents, in a continuous development, the ideas of moral compulsion and personal growth. In Augustine’s interpretation of the biblical text, the foundations of natural law are provided, such that morality is not simply the fruit of consensus. Man is seen not only as a product of history, even though he cannot be understood outside of it. The natural order and the supernatural order (...) are this way tied together. (shrink)

This essay represents a serious but fictional obituary of a scientific concept called the Threshold Dose–Response Model, which has long dominated the fields of toxicology and the broader biomedical sciences. Recent evidence indicates that the Threshold Dose–Response Model has long outlived its utility to predict low‐dose effects. In fact, so poorly does this model predict low‐dose responses that the idea arose that it should receive a symbolic burial recounting its achievements and failings, hence this obituary.

The purpose of the article is to show that the foundations of a dualistic theology of Christian roots are found in the point of connection between platonic metaphysics, gnostic myths and exegesis. It highlights the way in which platonic metaphysics was developed in a completely different way than what is known as “Metaphysics of Exodus”. It considers that myth ─as an expressive vehicle of religious experience and having a polyvalent logic─ was a decisive element for the transmission of gnostic tradition. (...) Thus, the article concentrates on the gnostic understanding of “The Prologue of John”, which focuses on the Christological function of Jesus, bearing in mind the difficulties involved in the indifference with which this tradition dealt with Incarnation. The tools for the exegesis are taken from Hellenic tradition as a form to clarify the gnostic intuition concerning the stages of the propagation of the divine, both before and after the Fall.

Partimos de la consideración de los saberes de las humanidades, y de la con-secuente formación humanística, para observar su injerencia y justificación en los resultados culturales, según la narrativa de Thomas Mann. Con el marco de la situación histórica del autor y dentro de la confrontación entre el burgués y el artista, analizamos el diagnóstico del autor sobre la época capitalista y su agotamiento; nos detenemos en la idea de evolución-transición operada por el arte, en particular por la música, como (...) lenguaje para renovar la tradición. La descripción de las formas ficcionales se realiza a través del aparente contraste de Doktor Faustus entre el narrador testigo, Serenus Zeitblom, y el protagonista, Adrián Leverkuhn, que revela la unidad de visión. Las conclusiones refieren a la dudosa energía de los saberes de las humanidades, y a la complicidad de sus mutaciones, bajo paradigma de racionalidad instrumental, para favorecer la crisis del individuo occidental.
