Este estudio buscó describir e interpretar las teorías subjetivas sobre la identidad profesional docente que se construyen y difunden noticiosamente durante la educación de emergencia por la pandemia de COVID 19. Se utilizó un estudio de análisis documental, metodología cualitativa y un diseño de estudio de casos. El muestreo intencionado y por conveniencia corresponde a 40 noticias de prensa escrita en español, sobre el profesor(a) en pandemia y publicadas en diferentes medios que fueron recolectadas a través de Google Noticias desde (...) el 11 de marzo de 2020 y hasta el 01 de noviembre de 2020. A partir de una codificación temática, los resultados evidenciaron teorías subjetivas asociadas a las exigentes características, roles, funciones y valores con los que se identifica al profesorado durante la pandemia. El análisis mostró los distintos sentidos del ejercicio profesional y las competencias asociadas a su desempeño en la prensa. En la discusión, se utilizaron estudios relativos a la práctica docente para interpretar estos resultados. (shrink)

We consider the problem of measurement using the Lindblad equation, which allows the introduction of time in the interaction between the measured system and the measurement apparatus. We use analytic results, valid for weak system-environment coupling, obtained for a two-level system in contact with a measurer (Markovian interaction) and a thermal bath (non-Markovian interaction), where the measured observable may or may not commute with the system-environment interaction. Analysing the behavior of the coherence, which tends to a value asymptotically close to (...) zero, we obtain an expression for the time of measurement which depends only on the system-measurer coupling, and which does not depend on whether the observable commutes with the system-bath interaction. The behavior of the coherences in the case of strong system-environment coupling, found numerically, indicates that an increase in this coupling decreases the measurement time, thus allowing our expression to be considered the upper limit for the duration of the process.

Atualmente, biotecnologias são empregadas na forma de protocolos a fim de sincronizar o crescimento folicular e a ovulação, bem como permitir que vacas atuem como receptoras de embriões visando melhorar o potencial genético do rebanho. O objetivo desse estudo foi avaliar o efeito da utilização de implantes intravaginais de progesterona de 1º, 2º e 3º uso no protocolo de transferência de embriões em tempo fixo (TETF) sobre a taxa de prenhez em receptoras girolandas. O experimento ocorreu em uma fazenda localizada (...) no município de São Sebastião do Maranhão (MG). Foram utilizadas 74 vacas submetidas aos seguintes protocolos: No dia 0 (D0) administrou-se 2 ml de 17β-Estradiol e progesterona e foi colocado o implante intravaginal de progesterona. Estes implantes foram colocados de forma aleatória, sendo de 1° uso (grupo 1; n=15), 2° (grupo 2; n=24) ou 3° (grupo 3; n=35).No D8, os implantes foram retirados e administrou-se 2 ml PGF2α; 1,5 ml de eCG e 1 ml de 17β-Estradiol e progesterona. A inovulação dos embriões in vitroo correu no D (16) para todas as vacas que apresentaram um corpo lúteo. As variáveis qualitativas (prenhe ou não prenhe) foram comparadas em tabelas de contingência e analisadas pelo teste de qui-quadrado a 5% de probabilidade. Neste estudo não houve diferença estatística entre os grupos protocolados em relação ao aproveitamento como receptoras: 1º uso (53,3%), 2º (79,2%) e 3º (68,65). Ademais, observou-se uma taxa de prenhez entre os grupos de 37,5% para o 1º uso, 42,1% para o 2º e 33,3% para o 3º (P>0,05). Dentre as vantagens ao reaproveitamento dos implantes multiusos destaca-se a redução dos custos dos protocolos hormonais, já que a progesterona é o hormônio mais oneroso, desta forma, a maximização do uso reduz o valor final do protocolo sem prejuízos a taxa de prenhez.

The numerical study of a glycolytic model formed by a system of three delay differential equations reveals a multiplicity of stable coexisting states: birhythmicity, trirhythmicity, hard excitation and quasiperiodic with chaotic regimes. For different initial functions in the phase space one may observe the coexistence of two different quasiperiodic motions, the existence of a stable steady state with a stable torus, and the existence of a strange attractor with different stable regimes (chaos with torus, chaos with bursting motion, and chaos (...) with different periodic regimes). For a single range of the control parameter values our system may exhibit different bifurcation diagrams: in one case a Feigenbaum route to chaos coexists with a finite number of successive periodic bifurcations, in other conditions it is possible to observe the coexistence of two quasiperiodicity routes to chaos. These studies were obtained both at constant input flux and under forcing conditions. (shrink)

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

Depuis une vingtaine d'annees, on assiste un peu partout a un regain d'interet pour les ecrits socratiques de Xenophon. Que Xenophon ne nous donne pas davantage que Platon un portrait historiquement fiable de Socrate peut etre considere comme un acquis de la critique du XXe siecle. Laissant transparaitre dans son temoignage des options profondement differentes de celles de Platon, Xenophon temoigne par la meme, cependant, des tensions, voire des oppositions qui traversaient le milieu socratique autour du souvenir et de la (...) comprehension de la personne de Socrate: cette seule consideration suffit a faire de Xenophon une source essentielle pour notre connaissance de l'immediat apres Socrate et, par dela, pour notre intelligence de l'histoire de la reception de Socrate dans les siecles ulterieurs. Le colloque dont sont issues les etudes rassemblees dans ce volume, organise a l'Universite de Provence (Aix-Marseille I) du 6 au 9 novembre 2003, s'inscrit dans cette perspective. Plus qu'un bilan de la nouvelle orientation des etudes xenophontiennes, qu'il est encore trop tot pour etablir, on y verra l'illustration de la diversite d'approches dont est susceptible le temoignage de Xenophon sur Socrate. Due a Louis-Andre Dorion, une bibliographie des etudes sur les ecrits socratiques de Xenophon publiees dans le dernier quart de siecle temoigne de la vitalite retrouvee de ce domaine de recherche.

Cells are the fundamental building blocks of organisms and their organization holds the key to our understanding of the processes that control Development and Physiology as well as the mechanisms that underlie disease. Traditional methods of analysis of subcellular structure have relied on the purification of organelles and the painstaking biochemical description of their components. The arrival of high‐throughput genomic and, more significantly, proteomic technologies has opened hereto unforeseen possibilities for this task. Recently two reports(1,2) show how much can be (...) gleaned from the combination of analytical centrifugation, mass spectrometry and advanced statistical techniques focused on a high‐throughput analysis of the content and organization of plant and animal cells. The results reveal intriguing possibilities for the future and the possibility of mapping much of the known proteome onto our current map of the cell.

The scientific literature highlights the risk of the appearance of internalizing and externalizing symptoms, together with difficulties in the academic area, linked to diagnosis of Attention Deficit Hyperactivity Disorder. This is normally assessed by teachers and primary caregivers, disregarding the self-perception of the adolescents themselves, which limits detection of this disorder at an evolutionary stage. Our aim was to analyze the psychometric properties of a self-report for ADHD in adolescence and its relationship with psychopathology and academic performance. This study assessed (...) an incidental sample of 267 students from secondary schools in the Region of Murcia, Spain, using the EDAH questionnaire adapted for self-report, in order to analyze its psychometric properties in assessing ADHD. The Youth Self-Report and the Brief Self-Control Scale were also used to determine their association with psychopathological, self-control and academic performance variables. An ADHD prevalence of between 3.7 and 13.1% was observed depending on the established cut-off point. The adapted EDAH showed adequate reliability indices and explained a high variance percentage. Adolescents with anxiety/depression difficulties, dissocial behavior, aggressiveness, and poor performance in mathematics showed a higher amount of ADHD symptoms. Moreover, self-control, dissocial behavior, age, and performance in Social Sciences acted as predictors of the disorder. The good psychometric properties of this questionnaire and its adequate correspondence with other variables of interest suggest it is an appropriate self-report instrument to assess ADHD in adolescence.

This paper takes the view that compensated donation and altruism are not incompatible. In particular, it holds that the arguments against giving compensation stand on weak rational grounds: the charge that compensation fosters “commodification” has neither been specific enough to account for different types of monetary transactions nor sufficiently grounded in reality to be rationally convincing; although altruism is commendable, organ donors should not be compelled to act purely on the basis of altruistic motivations, especially if there are good reasons (...) to believe that significantly more lives can be saved and enhanced if incentives are put in place, and offering compensation for organs does not necessarily lead to exploitation—on the contrary, it may be regarded as a necessity in efforts to minimise the level of exploitation that already exists in current organ procurement systems.

A proposal to allow prisoners to save their lives or to be eligible for commutation of sentence by donating kidneys for transplantation has been a subject of controversy in the Philippines. Notwithstanding the vulnerabilities associated with imprisonment, there are good reasons for allowing organ donations by prisoners. Under certain conditions, such donations can be very beneficial not only to the recipients but to the prisoners themselves. While protection needs to be given to avoid coercion and exploitation, overprotection has to be (...) avoided. The prohibition on the involvement of prisoners in organ transplantation constitutes unjustified overprotection. Under certain conditions, prisoners can make genuinely independent decisions. When it can be reasonably ascertained that they are able to decide freely, society should recognise an obligation to help them implement their decisions, such as when they intend to donate an organ as a way of asserting their religious faith and performing a sacrifice in atonement for their sins.

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

Dans une lettre à son épouse, Sade fait l'éloge de la bizarrerie et l’élève au rang de catégorie esthétique sous le nom de « principe de délicatesse ». Cela peut sembler paradoxal, comme l'a bien remarqué Michel Delon, que celui qui énonce le devoir de délicatesse est celui-là même dont le nom est devenu synonyme de brutalité. Le terme est en effet ambigu et possède dans l'oeuvre du marquis plusieurs sens: de l'échange de soins entre Juliette et sa maîtresse préférée (...) La Durand, en passant par une simple manie sexuelle, jusqu'à la fantaisie « la plus bizarre et la plus singulière de toutes », celle qui dépend d'une richesse fastueuse et qui ne s'achève que sur un tas de corps baignés de sang. Il s'agit d'abord d'examiner les différents sens du terme chez Sade ; puis d'analyser les interprétations que Roland Barthes, Annie Le Brun et Michel Delon donnent de la délicatesse scélérate ; enfin de mettre en évidence sa spécificité par rapport à la prodigalité luxurieuse.

Le statut théorique du rapport cognitif entre sujet et objet a été refusé par Sartre depuis ses premiers textes phénoménologiques et surtout dans L?Être et le Néant . C?est justement le rapport existentiel et immédiat de la conscience au monde, c?est-à-dire la conscience (de) soi, qui nous donne le point le plus substantiel dans la description phénoménologique sartrienne de la liberté. La conscience est plongée dans le monde et elle ne peut jamais lui échapper. Toutefois, elle peut quand même essayer (...) de se cacher à elle-même dans une conduite de mauvaise foi, bien que dans ce cas elle soit vouée à l?échec. C?est à partir du concept de mauvaise foi que la morale même devient possible dans la pensée du Sartre phénoménologue. La possibilité de conversion est ce qui permet de la préciser et de la définir ; autrement dit, d?envisager l?authenticité de la conscience dans sa relation à autrui. La description de la conversion, c?est ce qui nous renvoie au sens moral de la liberté à travers son rapport pratique dans le monde. Nous essayerons de reconstituer brièvement le parcours qui a amené Sartre à cette idée fonda­mentale. 1. Le refus du théorétisme dans la philosophie existentielle sartrienne La phénoménologie sartrienne des années 1930 et même celle de L?Être et le Néant s?est développée dans un dialogue constant avec Husserl. Bien qu?une influence plus nette de Heidegger soit apparue plus tôt à partir. (shrink)

La vida y obra del polígrafo granadino Lisān al-Dīn Ibn al-Ḫaṭīb (m. 776/1374) sigue siendo fuente de importantes estudios y traducciones habida cuenta de que su prolija producción literaria está repleta de valiosos testimonios históricos y personales que sitúan a su autor como un personaje destacado en la transmisión del conocimiento en el Mediterráneo islámico. En la difusión de su obra y prestigio jugó un papel fundamental la copia manuscrita de su obra al-Iḥāṭa fī aḫbār Ġarnāṭa que Ibn al-Ḫaṭīb envió (...) en vida (768/1366), a través de su hijo ʿAlī, a la ḫānqāh de Saʿīd al-suʿadāʾ de El Cairo, regida por el tremeceno Ibn Abī Ḥaǧala (m. 776/1375). El conocimiento de esta copia ha llegado hasta nosotros a través de otro tremeceno, al-Maqqarī (m. 1041/1632) y su monumental obra, Nafḥ al-ṭīb, en honor al sabio granadino. Gracias a ella sabemos, entre otras cosas, que esta copia fue profusamente consultada y comentada en sus márgenes. Dos autores destacan por encima de los demás: el hijo del autor Abū l-Ḥasan ʿAlī (m. s. IX/XV), y el magrebí Ibn Marzūq (m. 781/1379). A través del estudio y la traducción de las notas manuscritas de este manuscrito cairota, este estudio pretende poner de relieve el valor de los marginalia como fuente documental, así como arrojar un poco más de luz sobre estas dos figuras, junto con al-Maqqarī, como piezas importantes en la transmisión y pervivencia de la obra de Ibn al-Ḫaṭīb en el Oriente islámico hasta al menos el siglo XI/XVII.

The role played by the movement of the ‘novatores’ determined the introduction of philosophical scientific European thought in Spain and was essential for the later development of Enlightment in Spain. Juan de Nájera represented the standard of modern thinker at the begining of the century and he intended to reconcile modern ideas with more traditional positions. He was a very example of a trend shared by most ‘novatores’ in early Eighteenth Century in Spain.

La evidencia comparativa reciente sugiere que algunas especies no humanas sienten empatía hacia otros congéneres, la cual es una capacidad necesaria para la presencia y evolución de la moralidad. Por otro lado, la Hipótesis del Cerebro Social plantea relaciones entre la evolución de la neocorteza cerebral en primates y el tamaño de sus grupos sociales. Este artículo vincula estas ideas al señalar que: (i) la empatía y la moralidad son subproductos de la expansión de la neocorteza cerebral, y (ii) la (...) función de tales capacidades es facilitar la cooperación entre individuos, aumentando su cohesión social. Recent comparative evidence suggests that some nonhuman species feel empathy towards fellow group members and empathy is a necessary capacity for the presence and evolution of morality. On the other hand, the Social Brain Hypothesis suggests relationships between the evolution of brain's neocortex in primates and the size of their social groups. This paper links these ideas by suggesting that (i) empathy and morality are by-products of the expansión of brain's neocortex, and that (ii) the function of such capacities is to facilitate cooperation between individuals, increasing their social cohesion.

En este artículo se analizan las características de la transferencia de conocimiento desde unas disciplinas concretas, las humanidades y ciencias humanas, hacia sus respectivos sectores de aplicación. En primer lugar, se pone en evidencia que la transferencia de conocimiento es un concepto complejo y en evolución. En segundo lugar, se caracteriza la transferencia de conocimiento en estas disciplinas; para ello, se analizan los factores que influyen en la transferencia sobre la base del modelo de Bozeman (2000) y de la información (...) obtenida a partir de entrevistas realizadas a responsables de grupos de investigación de este ámbito en el Consejo Superior de Investigaciones Científicas. Los resultados obtenidos muestran que las características de las diversas dimensiones del proceso de transferencia (agentes, contenidos, medios, destinatarios y entorno), las barreras y los mecanismos más adecuados para lograr una eficiente transferencia de conocimiento, son notablemente diferentes en las humanidades que las que se dan en las ciencias experimentales o las ingenierías.

This article explores the relationship between Heidegger’s philosophy and poetry in his habilitation and his first lectures in Freiburg. Although poetry as a particular phenomenon was not yet thematized by Heidegger, philosophy and language developed in its proximity since the habilitation text. Subsequently, a tragic quotation exemplifies the characterization of language as a premundane generality in his first lessons. The article elaborates an interpretation of the implicit relationship between philosophy and poetry based on the pre-mundane language [Vorweltliche] and its critique (...) of neo- Kantianism. This relationship is the phenomenological possibility of letting see through language, especially the phenomena of world and meaning. Therefore, phenomenology and poetry came together in Heidegger’s thought around those two central phenomena of his later ontology. (shrink)

Reply to a commentary by Felicitas Holzer and Ignacio Mastroleoon “Models of Consent to Return of Incidental Findings in Genomic Research.”.

Se analiza, en este estudio, la sintáctica, la semántica y la pragmática del conflicto en una muestra de 359 profesores de enseñanza no universitaria en España. Se establece la vinculación entre las dimensiones de la sintáctica del conflicto y los modos o estrategias de afrontamiento del conflicto propuestos por Kreidler, 1984. Los resultados apuntan hacia una visión negativista de la realidad del conflicto como fruto de la cultura, aunque con ciertos indicios de positividad en cuanto a la pragmática del conflicto.
