The coronavirus disease 2019 pandemic is altering dynamics in academia, and people juggling remote work and domestic demands – including childcare – have felt impacts on their productivity. Female authors have faced a decrease in paper submission rates since the beginning of the pandemic period. The reasons for this decline in women’s productivity need to be further investigated. Here, we analyzed the influence of gender, parenthood and race on academic productivity during the pandemic period based on a survey answered by (...) 3,345 Brazilian academics from various knowledge areas and research institutions. Productivity was assessed by the ability to submit papers as planned and to meet deadlines during the initial period of social isolation in Brazil. The findings revealed that male academics – especially those without children – are the least affected group, whereas Black women and mothers are the most impacted groups. These impacts are likely a consequence of the well-known unequal division of domestic labor between men and women, which has been exacerbated during the pandemic. Additionally, our results highlight that racism strongly persists in academia, especially against Black women. The pandemic will have long-term effects on the career progression of the most affected groups. The results presented here are crucial for the development of actions and policies that aim to avoid further deepening the gender gap in academia. (shrink)

Beaucoup de « géomètres » du XIXe siècle - Bernhard Riemann, Hermann von Helmholtz, Felix Klein, Riccardo De Paolis, Mario Pieri, Henri Poincaré, Federigo Enriques, et autres - ont joué un rôle important dans la discussion sur les fondements des mathématiques. Mais, contrairement aux idées d'Euclide, ils n'ont pas identifié «l'espace physique» avec« l'espace de nos sens». Partant de notre expérience dans l'espace, ils ont cherché à identifier les propriétés les plus importantes de l'espace et les ont posées à la (...) base de la géométrie. C'est sur la connaissance active de l'espace que les axiomes de la géométrie ont été élaborés ; ils ne pouvaient donc pas être a priori comme ils le sont dans la philosophie kantienne. En outre, pendant la dernière décade du siècle, certains mathématiciens italiens - De Paolis, Gino Fano, Pieri, et autres - ont fondé le concept de nombre sur la géométrie, en employant des résultats de la géométrie projective. Ainsi, on fondait l'arithmétique sur la géométrie et non l'inverse, comme David Hilbert a cherché à faire quelques années après, sans succès. (shrink)

The purpose of this cross-sectional investigation was to examine the item characteristics, factor structure, reliability, convergent validity, and construct validity of the Psychobiosocial States in Physical Education (PBS-SPE) scale. In Study 1, a sample of 1,030 students (582 girls and 448 boys, 10 to 19-year-olds), drawn from middle or high schools, rated the intensity of the 20 items version of the PBS-SPE scale thinking about the feelings they had usually experienced in physical education classes. In Study 2, an additional sample (...) of 1,025 students (578 girls, 447 boys, 10 to 19-year-olds), rated the 16 items of the final version of the scale. Two subsamples also completed an affective-related measure (i.e., the Physical Activity Enjoyment Scale) and two motivation scales often used in the physical education domain (i.e., the Teacher-Initiated Motivational Climate in Physical Education Questionnaire and the Situational Motivation Scale). Exploratory structural equation modeling and confirmatory factor analyses of the data showed that a two-factor, 16-item solution (i.e., 8 pleasant/functional items and 8 unpleasant/dysfunctional items) of the PBS-SPE scale reached satisfactory fit indices. Multi-group comparisons provided support for measurement and structural invariance across samples, gender, and age. Convergent and construct validity was also upheld. Overall, the findings offer support for the use of a new instrument in the assessment of psychobiosocial states in physical education settings. (shrink)

Severe acute respiratory syndrome‐coronavirus (SARS‐CoV)‐2′s origin is still controversial. Genomic analyses show SARS‐CoV‐2 likely to be chimeric, most of its sequence closest to bat CoV RaTG13, whereas its receptor binding domain (RBD) is almost identical to that of a pangolin CoV. Chimeric viruses can arise via natural recombination or human intervention. The furin cleavage site in the spike protein of SARS‐CoV‐2 confers to the virus the ability to cross species and tissue barriers, but was previously unseen in other SARS‐like CoVs. (...) Might genetic manipulations have been performed in order to evaluate pangolins as possible intermediate hosts for bat‐derived CoVs that were originally unable to bind to human receptors? Both cleavage site and specific RBD could result from site‐directed mutagenesis, a procedure that does not leave a trace. Considering the devastating impact of SARS‐CoV‐2 and importance of preventing future pandemics, researchers have a responsibility to carry out a thorough analysis of all possible SARS‐CoV‐2 origins.

L’agiografia fa parte dei generi letterari nei quali si esprimono con più libertà concezioni teologiche e morali non convenzionali, che ci svelano un Medioevo meno uniforme di come lo si immagina. L’articolo presenta alcuni esempi tratti da testi originari di diverse aree, dal Mediterraneo greco all’Irlanda, dall’epoca tardoantica al basso Medioevo. Di santi come il bretone Macuto, Epifanio di Salamina, i martiri edesseni e svariati abati irlandesi si narrano azioni mosse da permalosità, vendicatività, gelosia, competizione. Ancora nelle storie di santi (...) irlandesi, tra cui Brigida, compare il miracolo dell’eliminazione di un feto indesiderato dal grembo della madre. Il bolognese Procolo è celebrato per aver assassinato a sangue freddo il suo persecutore. La greca Irene è assunta fisicamente in cielo. Nella Navigatio Brendani, infine, la figura di Giuda è oggetto di una pietà del tutto eccezionale. Tutte queste anomalie generano alcune reazioni di censura e mitigazione nella ricezione e trasmissione dei testi, ma fondamentalmente sono accettate e conservate, testimoniando l’apertura e varietà dottrinale ancora possibile in epoca medievale. Hagiography is one of the literary genres in which unconventional theological and moral conceptions are most freely expressed, revealing a less uniform Middle Ages than we imagine. The article presents some examples from texts originating in different areas, from the Greek Mediterranean to Ireland, from late antiquity to the late Middle Ages. Saints such as the Breton Macutus, Epiphanius of Salamis, the Edessenian martyrs and several Irish abbots are described as acting out of touchiness, vindictiveness, jealousy and competition. In the stories of other Irish saints, including Bridget, we read the miracle of the elimination of an unwanted foetus from his mother’s womb. The Bolognese Proculus is celebrated for having cold-bloodedly murdered his persecutor. The Greek Irene is physically assumed into heaven. Finally, in the Navigatio Brendani, the figure of Judas is granted a quite exceptional piety. All these anomalies arouse some reactions of censorship and mitigation in the reception and transmission of these texts, but fundamentally they are accepted and preserved, testifying to the doctrinal openness and variety still possible in medieval times.

The article considers three episcopal assemblies held in Gaul, which the manuscript tradition has not preserved, all involved in doctrinal debates on grace and free will. The first two, the council of Arles and the synod of Lyon, took place in the second half of the fifth century and concerned the affair of the presbyter Lucidus. The third is the Council of Valence that met just before the Second Council of Orange (529), that is, the council that marks the “resolution” (...) of the conflict and also the only documented. With the idea that the history of the councils occupies important points in the reconstruction of the debate on grace and free will, even in the case of councils whose acts have not been transmitted, the article seeks to enhance these three events by reconsidering indirect sources. The episcopal meetings of Arles, Lyon, and Valence are, indeed, an integral part of the doctrinal work on grace and free will, which for about a century interested monastic and ecclesiastical circles in Gaul. Moreover, the recovery of their history restores well the complexity of the cultural, religious and political climate in which they took place. (shrink)

This article examines the story of Jesus’ birth as it is presented in some of the so-called Apocryphal Infancy Gospels that have always aroused great interest in popular culture and in the arts. These texts describe the birth of Jesus by means of an important ‘narrative expansion’: the childbirth of Mary takes place in a cave, one or more midwives as well as two animals, the ox and the donkey, are added to the scene. These narratives do not relate the (...) preaching of Jesus, his death on the cross and his resurrection, but they present the event of his birth as a new beginning for all mankind. In doing so they reflect early Christian questions concerning Jesus’ nature. Examining some characteristic elements of this narrative development of the birth of Jesus, this article tries to show how this nativity may correspond to the construction of a myth. (shrink)

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

The book offers insights on whether international law can shape the politics of the Security Council and, conversely, the extent to which the latter contribute to the development of international law. By providing a systematic analysis of the quantity and quality of international legal instruments referred to in the text of resolutions, the book reconstructs patterns of the Security Council's behavioural regularities and assesses them against the provisions of the United Nations Charter, which establishes its mandate. The analysis is divided (...) into three periods - the origins and Cold War period, post-Cold War period and the twenty-first century - and assesses the resolutions passed in each period by thematic category. The book argues that while international law plays an important role in shaping the politics of the Security Council, the Council's resolutions do not contribute significantly to the development of international law.

Resumen: El presente artículo distingue principios epistemológicos que darían forma al oficio investigativo de la antropología. Se trata de presupuestos teóricos que encauzarían la práctica de una disciplina basada en un método de observación cualitativa, y en el registro sistemático de aquello observado bajo la forma de una huella subjetiva. En este trabajo se reflexiona sobre la postura ética implicada en el reconocimiento y explicitación de un locus investigativo, que sustentaría, a su vez, la articulación de un discurso aclaratorio con (...) carácter demostrativo. Un hipotético investigador será consciente de la representación multidimensional y subjetiva del fenómeno que observa, manteniéndose a resguardo de la acción interpretativa inmediatista y prescriptiva. En el marco conceptual que nos provee Bourdieu, la interpretación entrañará, en este caso, un “modus operandi” como expresión práctica y un “sentido común” como manifestación cultural. Se propone aquí una observación meditativa, que derivaría en la co-implicación del sujeto antropológico en aquello que intenta explicar.: This paper identifies epistemological principles that would come to define the task of anthropological research. These principles are theoretical assumptions which would inform the practice of a discipline based on a method of qualitative observation, and on the systematic recording of the things observed with a markedly subjective tone. In this study, I offer a proposal on the ethical stance implicit in the acknowledgement and explicitation of the locus of research, which would in turn underpin the articulation of an explanatory discourse that is demonstrative in nature. A hypothetical researcher would be aware of the multi-dimensional and subjective representation of the phenomenon observed and shun immediatist or prescriptive interpretations. In the conceptual framework offered by Bourdieu, interpretation in this case would entail a modus operandi as a practical expression and “common sense” as a cultural manifestation. What is proposed here is a meditative observation that would result in the co-involvement of the anthropological subject in that which the anthropologist seeks to explain. (shrink)

Este artículo contiene una reflexión, en primer lugar, sobre la vinculación que se establece entre la lengua de la madre –en su variedad experiencial cualitativa y determinaciones históricas– y el fenómeno de la locura y el dolor existenciales. En particular, se aborda el vínculo entre la mencionada lengua y el equívoco encauzamiento de una emocionalidad “no sabida”, esquivada o negada, hacia actos y acciones del habla. En segundo lugar, se observa la relación entre la lengua materna y formas de locura (...) existencial, en experiencias de fragmentación comunitario-familiar y de secuelas de exilios y diásporas del siglo XX. En tercer lugar, examina la experiencia, autobiográfica y crítica, de la escritura etnográfica y testimonial de la lengua. En cuarto lugar, ensaya una mirada fenomenológica de una ‘locura oral’, condicionada por secuelas de exterminios históricos. No es fácil notar, a primera vista, el ambiguo nexo de los sujetos plurales con la lengua materna, su reflejo en la psique colectiva como forma solapada de locura, monomanía, alienación y subjetividad fragmentada. Así como tampoco se advierte el impacto de esta particularidad en la acción comunicativa y convivencia lingüística gregaria. (shrink)

Así como tampoco se advierte el impacto de esta particularidad en la acción comunicativa y convivencia lingüística gregaria.: This article contains, in the first place, a reflection on the link established between the mother's tongue -in its qualitative experiential variety and historical determinations- and the phenomenon of existential madness and grief, particularly with the distorted guiding of an “unidentified” emotionality, eluded or denied, towards speech acts. In the second place, the relationship between the mother’s tongue and different types of existential madness, in the context of community-family fragmentation experiences and sequels of exiles and diasporas of the twentieth century, is observed. In the third place, the autobiographical and critical experience of ethnographic and testimonial writing of the language is examined. Finally, this article aims to establish a phenomenological view of an ‘oral madness’, conditioned by sequels of historical extermination. It is not easy to notice, at first glance, the ambiguous nexus of plural subjects with the mother’s tongue, its reflection in the collective psyche as a concealed form of madness, monomania, alienation and fragmented subjectivity. Likewise, the impact of this particularity on communicative action and gregarious linguistic coexistence is neither easily noticed. (shrink)

The purpose of this essay is to elucidate the philosophical tools developed in George Steiner’s marvelous body of work. In his writings, he carries on a lucid observation and description of human spirit’s linguistic creation and formulation. His observations do not deviate from the way of a strict ethics inherited from ilustrated spiritual Judaism. His legacy about thought on language and his role as a contemporary culture’s critic leads us to a reflection on our continent and history. As an anthropological (...) work, it aims at a practical comprehension of gregariousness and to a psychic and physiological elucidation of the human phenomena. (shrink)

La autora realiza una aproximación crítica a la cultura jurídica de la izquierda, principalmente comunista, tomando como eje de su examen la posición interna o externa respecto del Estado adoptada por dicha cultura. El análisis se centra de manera especial en el problema de la "legislación de emergencia" y en sus consecuencias tanto en el tejido social como a efectos del problema de la legitimidad política.

The paper presents and discusses the processes and the results of a Systematic Review of the scientific literature conducted with the aim to become aware of how the antisocial behaviour of adolescents are understood and educationally managed. The results show how the phenomenon is understood mainly through an explanatory and experimental epistemological and methodological approach. Such approach aims at identifying several risks and protection factors that determine/influence AB as well as at defining indications on the practices to be implemented for (...) the design of adequate prevention programmes. Based on these results, the paper proposes some critical reflections on a deterministic conception of AB. (shrink)

Both Carnap and Quine made significant contributions to the philosophy of mathematics despite their diversedviews. Carnap endorsed the dichotomy between analytic and synthetic knowledge and classified certainmathematical questions as internal questions appealing to logic and convention. On the contrary, Quine wasopposed to the analytic-synthetic distinction and promoted a holistic view of scientific inquiry. The purpose of thispaper is to argue that in light of the recent advancement of experimental mathematics such as Monte Carlosimulations, limiting mathematical inquiry to the domain of (...) logic is unjustified. Robustness studies implemented inMonte Carlo Studies demonstrate that mathematics is on par with other experimental-based sciences. (shrink)

This paper investigates the emotional import of literary devices deployed in fiction. Reflecting on the often-favored approach in the analytic tradition that locates fictional characters, events, and narratives as sources of readers’ emotions, I attempt to broaden the scope of analysis by accounting for how literary devices trigger non-cognitive emotions. I argue that giving more expansive consideration to literary devices by which authors present content facilitates a better understanding of how fiction engages emotion. In doing so, I also explore the (...) somatic dimension of reading fiction. (shrink)

Postcolonial science studies entails ostensibly contradictory critical and empirical commitments. Science studies scholars influenced by Bruno Latour and Isabelle Stengers embrace forms of realist, radical empiricism, while postcolonial studies scholars influenced by Jacques Derrida trace the limits of the knowable. This essay takes their common use of the term cosmopolitics as an unexpected point of departure for reconciling Derrida’s program with Stengers’s and Latour’s. I read Derrida’s critique of hospitality and Stengers’s and Latour’s ontological politics as necessary complements for conceiving (...) a care-oriented subalternist cosmopolitics, a process of composing common worlds that remains attentive to the limits of representation.

This paper concerns late 1920 s attempts to construct unitary theories of gravity and electromagnetism. A first attempt using a non-standard connection—with torsion and zero-curvature—was carried out by Albert Einstein in a number of publications that appeared between 1928 and 1931. In 1929, Tullio Levi-Civita discussed Einstein’s geometric structure and deduced a new system of differential equations in a Riemannian manifold endowed with what is nowadays known as Levi-Civita connection. He attained an important result: Maxwell’s electromagnetic equations and the gravitational (...) equations were obtained exactly, while Einstein had deduced them only as a first order approximation. A main feature of Levi-Civita’s theory is the essential use of the Ricci’s rotation coefficients, introduced by Gregorio Ricci Curbastro many years before. We trace the history of Ricci’s coefficients that are still used today, and highlight their geometric and mechanical meaning. (shrink)
