Medical and public health research includes surveys, interviews, and biospecimens — techniques that do not present substantial risks to subjects. Consequently, this research is exempt from regulation under the Federal Common Rule. Nevertheless, at many institutions, exempt research is frequently subject to the same regulatory process that is required for non-exempt research, requiring the consumption of time and resources for review by Institutional Review Board members or staff. The federal government has indicated an intention to reform and centralize this system, (...) but has not yet specified the form that it will use instead. By examining the policies of the top 50 research institutions, this article assesses institutional practices surrounding exempt research, quantifies the extent of exempt-research review requirements, documents a problem of “over-compliance,” and makes recommendations for reform.

Circumcision is often claimed to be simpler, safer and more cost-effective when performed in the neonatal period as opposed to later in life, with a greater benefit-to-risk ratio. In the first part of this paper, we critically examine the evidence base for these claims, and find that it is not as robust as is commonly assumed. In the second part, we demonstrate that, even if one simply grants these claims for the sake of argument, it still does not follow that (...) neonatal circumcision is ethically permissible absent urgent medical necessity. Based on a careful consideration of the relevant evidence, arguments and counterarguments, we conclude that medically unnecessary penile circumcision—like other medically unnecessary genital procedures, such as ‘cosmetic’ labiaplasty—should not be performed on individuals who are too young (or otherwise unable) to provide meaningful consent to the procedure.

Media exposure can shape audience perceptions surrounding novel innovations, such as artificial intelligence (AI), and could influence whether they share information about AI with others online. This study examines the indirect association between exposure to AI in the media and information sharing about AI online. We surveyed 567 US citizens aged 18 and older in November 2020, several months after the release of Open AI’s transformative GPT-3 model. Results suggest that AI media exposure was related to online information sharing through (...) psychological proximity to the impacts of AI and positive AI performance expectancy in serial mediation. This positive indirect association became stronger the more an individual perceived society to be changing due to new technology. Results imply that public exposure to AI in the media could significantly impact public understanding of AI, and prompt further information sharing online. (shrink)

The evolution of the equation of mass conservation in fluid mechanics is studied. Following early hydraulic approximations, and progress by Daniel and Johann Bernoulli, its first expression as a partial differential equation was achieved by d’Alembert, and soon given definitive form by Euler. Later reworkings by Lagrange, Laplace, Poisson and others advanced the subject, but all based their derivations on the conserved mass of a moving fluid particle. Later, Duhamel and Thomson gave a simpler derivation, by considering mass flow into (...) and out of a fixed portion of space. The later propagation of these derivations in nineteenth-century British textbooks and treatises is also examined, including Maxwell’s on the kinetic theory of gases. (shrink)

Two prevailing paradigms explain the diversity of sex-determining modes in reptiles. Many researchers, particularly those who study reptiles, consider genetic and environmental sex-determining mechanisms to be fundamentally different, and that one can be demonstrated experimentally to the exclusion of the other. Other researchers, principally those who take a broader taxonomic perspective, argue that no clear boundaries exist between them. Indeed, we argue that genetic and environmental sex determination in reptiles should be seen as a continuum of states represented by species (...) whose sex is determined primarily by genotype, species where genetic and environmental mechanisms coexist and interact in lesser or greater measure to bring about sex phenotypes, and species where sex is determined primarily by environment. To do otherwise limits the scope of investigations into the transition between the two and reduces opportunities to use studies of reptiles to advance understanding of vertebrate sex determination generally. © 2004 Wiley Periodicals, Inc.

La première partie du livre IV met apparemment en œuvre le programme didactique des Géorgiques, Virgile multipliant les conseils à l’apiculteur, quant au choix du lieu pour la ruche, à la sélection des espèces, aux aliments à mettre à disposition, à la récolte du miel, mais surtout aux précautions à prendre pour éloigner les abeilles des nombreux dangers potentiels qui les menacent, qu’il s’agisse du climat trop rigoureux ou de prédateu...

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

From the observation that global education systems are failing to produce beaming adults, this article questions the meaning of the words generally used to discuss education and new teaching methods. Sidestepping the panacea of technology as the holy grail, it suggests ideas for exploring other possible educational forms, such as those guided by the renewal of humanism or neurosciences. Then, this article presents a model of understanding of man and his activities, leading to the conception of a work system that (...) makes the most of the evolution of contemporary sciences, such as transdisciplinary thinking and transpersonal psychology. It gives an example of a concrete organization in vocational training for future teachers and proposes an evaluation of five years of practices that have encouraged transformations towards individual and collective achievement.

La formación docente es indispensable para responder a los requerimientos de la compleja sociedad actual. De su conocimiento, iniciativa, praxis y creatividad depende el éxito o el fracaso del sujeto que aprende. Al modificar el rol del docente se transforma la actitud de los estudiantes. ¿Cómo entender la formación filosófica transdisciplinar? Este texto responde a este y otros cuestionamientos: ¿cuáles son los planteamientos pedagógicos afines a la era digital? ¿en qué medida las TIC se encuentran al servicio de una filosofía (...) educativa transdisciplinar?, ¿cómo se explica ese enfoque en la formación del docente?, ¿cuál es la función de la formación en la innovación educativa?, ¿cómo formar para la ciudadanía mundial?, ¿cuáles son las contribuciones de las nuevas ciencias para la formación educativa? El crecimiento exponencial de la ciencia y de la tecnología nos obliga a pensar en procesos formativos innovadores. En tal sentido, resulta imprescindible el estudio de estas problemáticas. (shrink)

Anne Pasquier | : Le sermon Dolbeau 26 provient d’un manuscrit datant de la deuxième moitié du xve siècle qui sortit de l’oubli grâce à la publication, en 1990, d’un catalogue de manuscrits de la Stadtbibliothek de Mayence. Découvert par François Dolbeau, ce sermonnaire contient 63 sermons d’Augustin et un de Césaire d’Arles. L’intérêt pour ces oeuvres est d’autant plus grand que plusieurs des sermons sont partiellement ou complètement inédits. C’est le cas du sermon D. 26 en lequel s’élaborent (...) plusieurs réflexions qu’Augustin exprimera par la suite dans la Cité de Dieu. Dans le cadre de cet article, seront examinés les thèmes et les enjeux identitaires que l’on peut déceler en particulier dans les chapitres 1 à 9 de ce sermon. | : The sermon called Dolbeau 26 is part of a manuscript dating from the second half of the 15th century which came out of oblivion thanks to the publication, in 1990, of a catalogue of manuscripts in the Stadtbibliothek Mainz. Discovered by François Dolbeau, this manuscript contains 62 different sermons from Augustine, and one from Caesarius of Arles. The fact that 26 of those sermons from Augustine are partially or completely unknown explains their great interest. This is the case of the sermon D. 26 in which Augustine develops many reflections that will be later expressed in the City of God. In the context of this article, will be examined the identity issues that can be detected particularly in chapters 1-9 of this sermon. (shrink)

Research has repeatedly confirmed that farmer field schools can serve as a bridge between science and farm practice, enhancing simultaneously rural social energy. However, even though social capital is a burgeoning topic in FFS research, it is not clear whether and how it mediates FFS performance. In this mixed-methods study, using data from two FFS projects conducted in Greece, we examined if social capital among trainees facilitates the co-creation of knowledge and the co-development of agricultural innovations by farmers. A thematic (...) analysis was performed to analyse qualitative data, whereas regression models were employed for the quantitative strand of analysis. Results revealed that social capital evolves progressively during FFS, enabling the achievement of the project’s aims by enhancing in-group communication, establishing affective ties, instilling a sense of community, and triggering motivational contagion among participants. Statistical analyses confirmed that the “softest” sides of social capital significantly contribute to knowledge and innovation co-production. Although this work was based on data derived only from two FFS projects that took place in Greece, our findings underline the importance of social capital for the success of any FFS project and emphasise the need for identifying routes to nurture social capital within FFS.

La quatrième Géorgique n’est pas le simple entrelacs d’une didactique et d’une esthétique délicate et raffinée. Un troisième fil complique et parachève la tresse : la description ethnographique de la vie des abeilles.

On a pu parler à ce propos de « communiste monarchique » : les abe...

Peu à peu, tandis que Virgile achève la description ethnographique de la ruche, un glissement s’opère dans son propos : il célèbre d’abord la chasteté des abeilles, et le renouvellement de l’espèce par une miraculeuse génération spontanée ; il explique ensuite leur admirable organisation sociale par un lien privilégié avec la divinité, puisque les abeilles posséderaient une « parcelle d’intelligence divine » ; après ce bref aperçu d’une mystique panthéiste, i...

Control measures, such as “lockdowns”, have been widely used to suppress the COVID-19 pandemic. Under some conditions, they prevent illness and save lives. But they also exact an economic toll. How should we balance the impact of such policies on individual lives and livelihoods (and other dimensions of concern) to determine which is best? A widely used method of policy evaluation, benefit–cost analysis (BCA), answers these questions by converting all the effects of a policy into monetary equivalents and then summing (...) them up. A different method, social welfare analysis, proceeds by determining the effects of a policy on individual wellbeing and then applying an aggregation formula to them to evaluate the overall effects of a policy. In this chapter, we survey these methods and argue that social welfare analysis has important advantages. One crucial advantage is that it enables ethical considerations relating to the impact of policies on individual wellbeing and its distribution to be incorporated into policy assessments in a transparent way. We illustrate this with a simple numerical model for evaluating pandemic policies that vary in terms of the stringency of the controls that they impose on individual behaviour, showing how the evaluation depends on the ethical significance accorded to their impact on the wellbeing of different age and income groups.

Scholars have long pointed to the power of music as a primary source in instruction for bringing past actors into sharper view and engender deeper connections with the past. By employing Dimitri Shostakovich's 7th Symphony, composed amidst the Nazi siege of Leningrad during the Second World War, we sought to explore, more precisely, the nature of how music, as a primary source, enhances the study of history among students. Through the formulation, execution, and assessment of a two-day lesson with students (...) in five secondary history classes, three of which listened to the symphony and two of which did not, we found that the incorporation of the symphony resulted in students’ enhanced empathetic understanding of the past. Implications include details regarding profound opportunities for, as well as challenges to, cultivating historical empathy through the use of music as a primary source. (shrink)

Depuis son retour, j’étais rongé. J’abrégeais les conversations, évitais son regard.

Social scientists have not integrated relevant knowledge from the biological sciences into their explanations of human behavior. This failure is due to a longstanding antireductionistic bias against the natural sciences, which follows on a commitment to the view that social facts must be explained by social laws. This belief has led many social scientists into the error of reifying abstract analytical constructs into entities that possess powers of agency. It has also led to a false nature-culture dichotomy that effectively undermines (...) the place of biology in social scientific explanation. Following the principles of methodological individualism, we show how behavioral explanations supported by data and theory from the neurosciences can be used to correct the errors of reificationist thinking in the social sciences. We outline a mechanistic approach to the explanation of human behavior with the hope that the biological sciences will begin to find greater acceptance among social scientists. (shrink)

La complejidad del mundo actual demanda de nuevas formas de pensar, diferentes a las convencionales. La educación exige cambios acelerados en la formación de los seres humanos. Cambios impredecibles que toman por sorpresa, quizá se está frente a una transformación en contextos geográficos, comunicación, convivencia con los ‘otros’; todo ello afectado por las transformaciones constantes. A la par de estas transformaciones, las grandes problemáticas sociales, ambientales, políticas, económicas continúan creciendo, no se logra alcanzar una sostenibilidad en el estilo de vida (...) de las sociedades. Es cierto que estamos en un mundo globalizado gracias a la Internet y a las Tecnologías de la Información y la Comunicación (TIC), por consecuente la información está al alcance de la mayoría de los seres humanos. Si el planeta está al frente de una globalización tecnológica, la educación también debe globalizarse, sin perder la identidad local. De ahí nace el desafío de reinventar los procesos de formación, direccionarlos hacia la transformación social, y al desarrollo de competencias profesionales básicas como el ‘aprender a vivir juntos’ bajo los cánones éticos que como civilización históricamente se practica.

Active inference offers a unified theory of perception, learning, and decision-making at computational and neural levels of description. In this article, we address the worry that active inference may be in tension with the belief–desire–intention model within folk psychology because it does not include terms for desires at the mathematical level of description. To resolve this concern, we first provide a brief review of the historical progression from predictive coding to active inference, enabling us to distinguish between active inference formulations (...) of motor control and active inference formulations of decision processes. We then show that, despite a superficial tension when viewed at the mathematical level of description, the active inference formalism contains terms that are readily identifiable as encoding both the objects of desire and the strength of desire at the psychological level of description. We demonstrate this with simple simulations of an active inference agent motivated to leave a dark room for different reasons. Despite their consistency, we further show how active inference may increase the granularity of folk-psychological descriptions by highlighting distinctions between drives to seek information versus reward—and how it may also offer more precise, quantitative folk-psychological predictions. Finally, we consider how the implicitly conative components of active inference may have partial analogues in other systems describable by the broader free energy principle to which it conforms.

It is argued that the constraints placed on the non-law premisses of a D–N explanation are irrelevant to their function and will not salvage the deductive requirement from triviality.
