Narrar la propia biografía después de un divorcio : notas de un estudio cualitativo de interés para la demografía

En este artículo se discuten algunos resultados de un estudio cualitativo sobre las trayectorias familiares que siguen hombres y mujeres que han vivido una ruptura de una unión en la que hubo hijos. Primero se presenta el diseño de la metodología cualitativa y luego se ofrecen algunos resultados del trabajo de campo realizado en áreas metropolitanas de España donde el divorcio tiene una intensidad mayor. Las narraciones de nuestros biógrafos y biógrafas permiten discutir a fondo el significado mutante de la familia y los vínculos afectivos en la llamada moderna sociedad líquida, y revisar de forma crítica tres conceptos básicos del análisis demográfico de las biografías de rupturas de unión: familia, la datación de los acontecimientos y los llamados factores determinantes.In this article some outcomes of a qualitative study on the familiar trajectories that follow men and women who have experienced a break-up of union in which there were children are discussed. The design of the qualitative methodology is first presented before showing some results of the fieldwork done in metropolitan areas of Spain where the divorce has a greater intensity. The narrations of our biographers allow us to discuss the meaning of the family and the affective ties in the so-called liquid modern society and to review three basic concepts of the demographic analysis of the biographies of union ruptures: family, timing of the events and the determinant factors.Dans cet article on discute quelques résultats d'une étude qualitative sur les trajectoires familiales qu'ils suivent des hommes et des femmes qui ont vécu une rupture d'une union dans laquelle il y a eu des enfants. On présente d'abord la conception de la méthodologie qualitative et on offre ensuite quelques résultats de la recherche effectué dans des secteurs métropolitains de l'Espagne où le divorce a une intensité plus grande. Les narrations de nos biographes permettent d'examiner en profondeur la signification mutant de la famille et les liens affectifs dans la moderne société liquide, et de réviser de manière critique trois concepts de base de l'analyse démographique des biographies de ruptures d'union: famille, datation des événements et facteurs déterminants

Maladaptive plasticity in levodopa-induced dyskinesias and tardive dyskinesias: old and new insights on the effects of dopamine receptor pharmacology.

Maladaptive plasticity can be defined as behavioral loss or even development of disease symptoms resulting from aberrant plasticity changes in the human brain. Hyperkinetic movement disorders, in the neurological or psychiatric realms, have been associated with maladaptive neural plasticity that can be expressed by functional changes such as an increase in transmitter release, receptor regulation, and synaptic plasticity or anatomical modifications such as axonal regeneration, sprouting, synaptogenesis, and neurogenesis. Recent evidence from human and animal models provided support to the hypothesis that these phenomena likely depend on altered dopamine turnover induced by long-term drug treatment. However, it is still unclear how and where these altered mechanisms of cortical plasticity may be localized. This study provides an up-to-date overview of these issues together with some reflections on future studies in the field, particularly focusing on two specific disorders (levodopa-induced dyskinesias in Parkinson's disease patients and tardive dyskinesias in schizophrenic patients) where the modern neuroimaging approaches have recently provided new fundamental insights
