Modos históricos de construcción de una excepcionalidad normalizante en los márgenes del estado argentino

Este trabajo responde a la convocatoria de los organizadores del “Primer Encuentro Patagónico de Teoría Política: Justicia, igualdad, poder popular” de repensar los supuestos y preguntas que llevamos adelante en nuestros equipos de investigación. En este sentido, se aborda una propuesta teórica para reflexionar, en líneas generales, sobre las formas de incorporación de los indígenas en Patagonia al estado nación argentino a partir de las campañas de ocupación militar a fines del siglo XIX y en particular a la relación que se constituye entre ambas agencias a partir del genocidio perpetrado por el estado en ese proceso. Por otra parte se propone indagar la relación entre soberanía y excepcionalidad y entre el estado y sus márgenes a partir del análisis histórico de la existencia de campos de concentración en el proceso del sometimiento indígena y el devenir de estos en la primera mitad del siglo XX.This article is aimed to answer the invitation of the organizers of the “First Patagonian Encounter on Political Theory: justice, equality, popular power” in order to rethink the assumptions and questions that we deal with in our research teams. Therefore, this piece deals with a theoretical approach that enables us to analyze the incorporation and expropriation of indigenous peoples and lands in Patagonia by the Argentinean national state since the genocidal process that began with the military campaigns of occupation by the late nineteenth century. At the same time, this article explores the relationship between sovereignty and exceptionalness as well as between the state and its margins from the historical research on the existence of concentration camps during the Campaign of the Desert and the aftermaths of this process during the first half of the twentieth century.Fil: Pérez, Pilar María Victoria.

Estado, indios y casas comerciales: el espacio social en el territorio nacional de Río Negro a principios del siglo XIX

A través de un análisis pormenorizado de un expediente proveniente de la Justicia Letrada, este artículo se propone profundizar en algunos supuestos de la historia regional, teniendo en cuenta la relación entre indígenas, comerciantes y funcionarios estatales en la zona andina rionegrina en las primeras décadas del siglo XX. Por medio de este análisis detallado se busca visibilizar diversos mecanismos de subalternización para con los indígenas que permiten historizar la relación entre el estado y sus márgenes y, al mismo tiempo, repensar la construcción del estado nacional a nivel local.Through a detailed analysis of a legal file, this paper proposes to review some common assumptions of Patagonian regional history. The focus is placed on the relationship between indigenous people, businessmen and state bureaucrats in the National Territory of Río Negro during the first decades of the twentieth century. Through this thorough study, different mechanisms of subalternization towards the indigenous population are visibilized. These mechanisms allow the researchers to historicize the relationship between the national state and its margins and, at the same time, it enables to refocus the study of the national state.Fil: Pérez, Pilar María Victoria.

La educación no formal : una vía para la participación de los padres en los centros educativos

Desde la educación no formal existen vías para que la familia y la escuela mantengan cauces de mutuo entendimiento que favorezca el desarrollo del alumnado en todas sus dimensiones. Actualmente, la participación de la familia en los centros educativos es muy baja, por diferentes motivos. Es por ello, que tanto desde las aulas, como desde la administración pública tiene que haber un apoyo para que poco a poco se vayan estrechando los lazos de unión entre estas dos instituciones que forman parte de nuestra vida diaria.The non-formal education is provided with means that enable the family and the school to keep streams of mutual understanding which favour students’ development in all its dimensions. Currently, family participation in educational centres is very low for different reasons. For this reason, there must be support from both classrooms and public administration in order to tighten the bounds of union between these two institutions which are part of our daily life

¿Qué tienen en cuenta los profesores cuando seleccionan el contenido de enseñanza? Cambios y dificultades tras un programa de formación

The selection and sequencing of syllabus content is one of the main tasks the teacher has to approach in his/her new role as curriculum designer. The teaching proposals produced should be theoretically-driven so that specific procedures are suggested for the analysis of disciplinary content and pupils' characteristics. Knowledge regarding teachers' beliefs about these proposals, the difficulties involved in learning them and their scope of application is necessary in order to analyze how adequate they might be for inducing educational changes. In this paper, we present the initial teaching beliefs and teaching practices of a group of secondary school teachers who had previously received a training course in which a teaching proposal was presented. Also, some information is outlined concerning their assessment of the proposal as well as the learning and educational changes effected

Volatiles from Subtropical Convolvulaceae That Interfere with Bacterial Cell-to-Cell Communication as Potential Antipathogenic Drugs

Increasing chronic bacterial infections create an urgent need for new antimicrobial agents or strategies for their control. Targetingvirulence is one of the alternative approaches to find new medicines to treat persistent infections due to bacteria with biofilmphenotypewhich are more resistant to antibiotics than their planktonic counterparts having an extreme capacity for evading the host defences. A bioguided study of sixteen extracts from flowers and leaves of four subtropical Convolvulaceae species provided evidence of the occurrence of antipathogenic natural products active against Gram positive and negative bacteria.Particularly, volatile metabolites from Merremia dissecta creeper, a food and medicinal plant, were able to interfere with the Pseudomonas aeruginosa quorum sensing system by a strong decrease of N-acyl homoserine lactone (AHL) biosynthesis (63?75%), which attenuated the virulence factor expression like biofilm (55%) and elastase activity (up to 27%), key factors thatenable the colonization and dissemination of the infection in the host. Control of the P. aeruginosa biofilm and the QS process by phytochemicals, such as (+) spathulenol, isolated from a bioactive extract of M. dissecta leaves would be a good strategy for the development of new and effective antipathogenic drugs.Fil: Luciardi, María Constanza.

The role of parenting styles on behavior problem profiles of adolescents

Parental behavior is one of the most influential factors on the development of adolescent externalizing and internalizing behavior problems. These behavioral problems are closely related and often co-occur. The objectives of this work were: (i) to identify adolescents profiles according to their behavior problems; (ii) to explore individual, family, and social characteristics associated with these profiles; and (iii) to analyze the potential role of parenting styles in belonging to adolescents’ profiles. A total of 449 Spanish adolescents (223 from families declared at-risk and enrolled in Child Welfare Services and 226 from families from the general population) participated in this study. The analyses revealed three profiles of adolescents based on external and internal behavior problems (adjusted, external maladjustment, and internal maladjustment). Parenting styles explained the adolescents’ belonging to different profiles, in which the indulgent style was the most favorable in general terms. The distinctive role of parenting styles on two types of maladjustment profiles was confirmed. The relationship between parenting styles and adolescent adjustment is a key component that should be included in interventions according to adolescents’ behavior problem profiles. Furthermore, the results shed light on the need that family interventions are complemented with individualized interventions with adolescents that accumulate stressful life events.Ministerio de Economía y Competitividad EDU2013-41441-
