Predictors of Growth and Distress Following Childhood Parentification: A Retrospective Exploratory Study
Abstract While most of the existing literature has focused on the risks associated with parentification, we examined the potential benefits (i.e., posttraumatic growth) associated with parentification. Predictors of posttraumatic growth explored in our study included: attachment, differentiation of self, parentification, and resiliency. Partial support was found for the predictor variables leading to posttraumatic growth, with resilience emerging as the strongest predictor; resilience explained 14% of the variance in posttraumatic growth. These findings suggest that future research might explore additional resiliency factors that explain positive psychological outcomes related to childhood parentification

Production of rVSV-ZEBOV in serum-free suspension culture of HEK 293SF cells.
Abstract Ebola virus disease is an urgent international priority. Promising results for several vaccine candidates have been reported in non-human primate studies and clinical trials with the most promising being the rVSV-ZEBOV vaccine. In this study, we sought to produce rVSV-ZEBOV in HEK 293SF cells in suspension and serum-free media. The purpose of this study was to establish a process using the HEK 293SF production platform, optimise the production titre, demonstrate scalability and the efficiency of the generated material to elicit an immune reaction in an animal model. Critical process parameters were evaluated to maximize production yield and process robustness and the following operating conditions: 1–2 × 106 cells/mL grown in HyClone HyCell TransFx-H media infected at an MOI of 0.001 with a temperature shift to 34 °C during the production phase and a harvest of the product after 48 h. Using these conditions, scalability in a 3.5 L controlled bioreactor was shown reaching a titre of 1.19 × 108 TCID50/mL at the peak of production, the equivalent of 4165 doses of vaccine per litre. The produced virus was shown to be thermostable in the culture media and, when concentrated, purified and administered to mice, demonstrated the ability to induce a ZEBOV-specific immune response

Sustentabilidad vitivinÃcola para diferentes tipos de agricultores vitivinÃcolas
Un Desarrollo Rural Sustentable requiere de sistemas agrÃcolas sustentables, que sean ecológicamente adecuados, económicamente viables y socio culturalmente aceptables Abbona et al, (2004). Sarandon, (2010), define la agricultura sustentable como aquella que es: suficientemente productiva, económicamente viable, ecológicamente adecuada y cultural y socialmente aceptable. En el contexto de cambio de la vitivinicultura, se hace necesario conocer la sustentabilidad de los mismos. En este caso se usó la tipologÃa que propuesta por MartÃn, (2009) que plantea tres tipos sociales: productores descapitalizados pluriactivos, productores familiares capitalizados y empresarios. El objetivo de este trabajo fue: analizar, mediante el método propuesto por Sarandón (2002) y el uso de indicadores, la sustentabilidad predial de tres modelos productivos vitivinÃcolas: productores descapitalizados pluriactivos, productores familiares capitalizados y empresarios, de la 1º zona de Mendoza. La propuesta de metodológica estuvo basada en la metodologÃa de Sarandón (2002) y estaba propuesto realizar tres etapas, de 2 años cada una. En una primera etapa se desarrollaron dos acciones. Lo primero fué buscar y analizar antecedentes e información regional sobre el tema y la segunda acción fue buscar y seleccionar 2 fincas del departamento de Lujan de Cuyo que fueran representativas, para cada tipo social, factibilidad de acceso y predisposición de los agricultores. En una segunda etapa se caracterizarÃa, a través del enfoque sistémico, el funcionamiento de los agroecosistemas en tres dimensiones: ambiental-ecológica, tecnológica, y socioeconómica. Y en una tercera etapa: se construirán indicadores para evaluar la sustentabilidad de los sistemas agrÃcolas, Se logró la primera etapa y se pudo: conceptualizar y profundizar el concepto de sustentabilidad integral y su aplicación en la agronomÃa, proponer variables con potencial de indicadores de sustentabilidad y seleccionar las fincas.A Sustainable Rural Development requires sustainable agricultural systems that are environmentally suitable, economically viable and culturally acceptable (Abbona et al, 2004). Sarandon (2010) defines sustainable agriculture as one that is: productive enough, affordable, ecologically appropriate and culturally and socially acceptable. In the context of the viticulture changes, it is necessary to study their sustainability. In this case we take the typology proposed by Martin, 2009 that summarizes it in three social types: pluriactive undercapitalized producers, family farmers and entrepreneurs capitalized. The objective of this work was to analyze, through the method proposed by Sarandón (2002) and the use of indicators, the property sustainability of three vitivinÃcolas production models: pluriactively de-capitalized producers, capitalized family producers and entrepreneurs, from the first zone of Mendoza. The methodological proposal was based on the methodology of Sarandon (2002) and was proposed to perform three stages, each of 2 years. In the first stage two actions were developed. The first was to seek and analyze regional background and information on the subject; And the second action was to search and select 2 farms in the department of Lujan de Cuyo that were representative for each social type, feasibility of access and predisposition of farmers. In a second stage, the systemic approach would characterize the functioning of agroecosystems in three dimensions: environmental-ecological, technological, and socioeconomic. And in a third stage: indicators will be constructed to evaluate the sustainability of agricultural systems, The first stage was achieved and it was possible to: conceptualize and deepen the concept of integral sustainability and its application in agronomy, propose variables with potential for sustainability indicators and successful selection of farms.Trabajo publicado en Filippini, MarÃa Flavia (comp.).

Letter processing and font information during reading: beyond distinctiveness, where vision meets design
Letter identification is a critical front end of the
reading process. In general, conceptualizations of the identification process have emphasized arbitrary sets of distinctive features. However, a richer view of letter processing incorporates principles from the field of type design, including an emphasis on uniformities across letters within a font. The importance of uniformities is supported by a small body of research indicating that consistency of font increases letter identification efficiency. We review design concepts and the relevant literature, with the goal of stimulating further thinking about letter processing during reading
