SummaryPedigree structures of 161 uncle/niece-aunt/nephew and 4420 first cousin consanguineous marriages registered during the 19th and 20th centuries in two large and very different Spanish regions have been analysed and their genetic consequences evaluated. The frequencies of the different pedigree subtypes within each degree of relationship were quite similar in both populations despite significant heterogeneity in inbreeding patterns. The mean X-linked inbreeding coefficient for each type of cousin mating was calculated and compared to that expected for autosomal genes. The effect (...) of genealogical structure on theFx/Fradio was compared to different cultural populations worldwide. Preferentiality and avoidance of close consanguinity along with specific types of pedigrees are discussed on the basis of premarital migration and sociocultural rules still deeply rooted in certain human groups. By admitting that the observedFxcoefficient is usually higher thanFin most human populations some remarks have been made in terms of population genetic risk. (shrink)

SummaryRecord linking provided information on the complete reproductive schedules of a sample of 1102 couples with at least two children born alive from a rural Spanish community characterised by very high extramarital reproduction. Birth spacing was analysed considering final family size as well as the legitimate–illegitimate status and sex of the newborn, and survival of the preceding sibling.

Si l’« explosion sociale » chilienne a rassemblé une série de mouvements sociaux, il est certain que les féminismes ont joué un rôle fondamental dans l’établissement de revendications contre les abus, les inégalités et la précarité de la vie. Malgré l’échec du rejet de la nouvelle Constitution, cet article approfondit deux normes minimales historiques que les féministes ont réussi à établir au niveau institutionnel et social : la parité dans la participation politique et la condamnation généralisée de la violence à (...) l’égard des femmes.

This essay examines the relationship between Eric Voegelin and Leo Strauss in order to show the central themes necessary to elucidate their philosophical positions. The essay reveals the centrality of the figure of Plato as a point of departure to understand the agreement and the disagreement concerning fundamental questions (such as the way of reading ancient texts, the importance of the historical perspective or the importance of the study of the past in order to orient the modern science) which revolves (...) around the issue of the relation between revelation and philosophy. The work concludes with an identification of the common core of both thinkers that allows us to understand their differences (homogeneity or heterogeneity of reality and the human) and, moreover, identifies both perspectives with a «foundational» (Voegelin) or «negative» (Strauss) interpretation of Plato’s thought.

Resumen: La sociedad requiere de forma creciente la realización efectiva de instancias participativas dirigidas a fomentar la colaboración entre distintos ámbitos organizacionales, disciplinarios y socio-culturales. Los desafíos intrínsecos a este tipo de instancias requieren el desarrollo de metodologías que permitan insertar reflexividad dentro del ámbito dialógico y orientar el mismo hacia la creación de “boundary objects” que pueda servir de referente entre las distintas perspectivas involucradas, constituyéndose en un facilitador para la colaboración futura. Para responder a estas necesidades, el artículo (...) elabora, a partir del concepto de metálogo originariamente propuesto por Gregory Bateson, una propuesta sistémico-constructivista de observación e intervención contextual, dirigida a fomentar reflexividad a partir de la promoción de observación de segundo orden. En este contexto de mayor reflexividad, se promueve la co-construcción de documentos donde se coordinen las perspectivas de los participantes y las expectativas de los arreglos estructurales y organizacionales en los que estos operan. El artículo justifica teóricamente y describe la técnica del metálogo, además de destacar aprendizajes, buenas prácticas y reflexiones derivadas de su aplicación en diversas experiencias transdisciplinarias en Chile.: Contemporary society shows an increasing demand for participatory instances able to effectively foster the collaboration of diverse organizational, disciplinary and socio-cultural areas. The challenges intrinsic to such participatory instances require the development of methodologies that may allow for the insertion of reflexivity within the dialogical interaction, while also promoting the collective construction of "boundary objects": such objects, in turn, by serving as a common reference for the different perspectives involved in the dialogue, have the potential of facilitating the future collaboration among such perspectives. To respond to these demands -and inspired by the notion of metalogue originally introduced by Gregory Bateson- this paper elaborates a systemic-constructivist proposal of observation and contextual intervention, aimed at fostering reflexivity within dialogical-participatory instances by inducing their participants to perform a second-order observation of the distinctions mobilized within the interaction. Building upon this reflexivity, the metalogue pursues the co-construction of documents able to coordinate the perspectives of the participants and the expectations of the structural and organizational arrangements in which they operate. In addition to justifying and describing the technique of the metalogue, the paper highlights some lessons learned, good practices and proposals derived from its application in various transdisciplinary experiences in Chile.
