In his thesis 'Para uma Teoria Geral dos Homomorfismos' (1944) the Portuguese mathematician José Sebastião e Silva constructed an abstract or generalized Galois theory, that is intimately linked to F. Klein’s Erlangen Program and that foreshadows some notions and results of today’s model theory; an analogous theory was independently worked out by M. Krasner in 1938. In this paper, we present a version of the theory making use of tools which were not at Silva’s disposal. At the same time, we (...) tried to keep in mind, so much as possible, the gist of his standpoint. (shrink)

This is a broad overview of how the prevalent family systems in the developing world influence sex preference for children. Son preference is evident in the data in East Asia and South Asia, and in the Middle East and North Africa, where patriarchal family systems make sons more valuable than daughters to parents in terms of economic, physical, and emotional sustenance. In sub-Saharan Africa, Latin America and Southeast Asia, there is little difference between the levels of support parents can expect (...) from sons and daughters—and little revealed sex preference in the data.

Le recueil d'études Contempler l'infini invite le lecteur à étudier la fonction de l'acte contemplatif dans son rapport à l'espace et au temps, en s'interrogeant notamment sur la valeur et la portée épistémiques de cet acte (d'un point de vue mathématique, philosophique, phénoménologique, esthétique, artistique, linguistique et poétique) lorsqu'il se détermine en relation à une réalité représentée comme "infinie" (Dieu, âme, cosmos, etc.). Ce livre est conçu dans un contexte éminemment interdisciplinaire, l'objectif étant de comprendre comment cette articulation subtile des (...) deux concepts peut être abordée selon des méthodologies et des lexiques très différents mais bien souvent complémentaires sur le plan épistémologique. Le recueil regroupe les études et les réflexions des chercheurs français et hongrois de différentes spécialités (mathématiques, philosophie, esthétique. phénoménologie, théologie, linguistique et littérature).

Body awareness refers to the individual ability to process signals originating from within the body, which provide a mapping of the body’s internal landscape and its relation with space and movement. The present study aims to evaluate psychometric properties and validate in French two self-report measures of body awareness: the Postural Awareness Scale, and the last version of the Multidimensional Assessment of Interoceptive Awareness questionnaire. We collected data in a non-clinical, adult sample using online survey, and a subset of the (...) original sample also completed the retest control. Factor analyses and reliability analyses were conducted. Construct validity of the PAS and the MAIA-2 were examined by testing their association with each other, and with self-report measures of personality, alexithymia and dispositional trait mindfulness. Factor analyses of the PAS supported the same two-factor structure as previously published versions. For the MAIA-2, factor analyses suggested that a six-factor structure, excluding Not-Worrying and Not-Distracting factors, could successfully account for a common general factor of self-reported interoception. We found satisfactory internal consistency, construct validity, and reliability over time for both the PAS and the MAIA-2. Altogether, our findings suggest that the French version of the PAS and the MAIA-2 are reliable self-report tools to assess both components of body awareness. (shrink)

Laymen occasionally have to write texts in specialized domains, such as when interacting with the public administration. However, in Spanish, most studies related to administrative texts have focused on texts written by the administration for laymen rather than texts that average citizens write to the administration. Against this backdrop, this article aims to carry out the following: a linguistic analysis on a corpus of Spanish-language texts from five textual genres written by laymen and addressed to the public administration on the (...) textual, lexical and discourse levels; a contrastive analysis that applies statistical techniques to quantitative data to identify significant differences among these textual genres. The results show a detailed and comprehensive understanding of the characteristics of each genre. Also, the statistical results indicate that there are significant differences among some of the analyzed genres. (shrink)

O ponto de partida do presente ensaio é o entendimento de que a arte constitui um dos motivos catalisadores, se não mesmo um dos temas maiores da reflexão de Maurice Merleau-Ponty. Na interpretação do autor, o filósofo da percepção, aquele que, de todos os pensadores contemporâneos, conferiu ao corpo po um estatuto que a reflexão do século XX ainda não lhe concedera, chegou à arte por necessidade intrínseca do seu próprio caminho especulativo, vindo a reflexão sobre a expressão artística a (...) dar um contributo essencial para a constituição do seu próprio pensamento, contributo esse que se vai adensando, desde a Fenomenologia da Percepção até O Visível e o Invisível e O Olho e o Espírito, a ponto de poder dizer-se que na arte, particularmente na arte moderna, encontrou Merleau-Ponty uma filosofia à l'oeuvre, apesar da ausência do conceito, a que é, de facto, alheia a expressão artística.

Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental health (...) was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)
