In most economic transactions involving software development projects, differences in the amount and quality of information possessed by economic agents (i.e. producers and customers) can lead to significant market inefficiencies. This paper describes the way the information derived from the functional size of software measured using the ISO 19761 COSMIC measurement standard that can help reduce information asymmetry in software development transactions, and lead to increased competitiveness in the software industry.

Valdés S,Gloria;
Revista médica de Chile , 2011, DOI: 10.4067/S0034-98872011000300019
Abstract: this review analyses the changes in immunological tolerance, and the systemic and local hemodynamic changes observed along human pregnancy. to underscore the conceptual importance of tolerance and adaptation the background isprovided by the two main advocates ofthese ideas: gandhi and darwin. the cognate factors that determine immunological tolerance (it), systemic (sa) and local adaptation (la) are múltiple; it = desensitisation to paternal antigens, absence of hla-a, roles of hla-g, natural killer cells and their receptors; sa = decreased vascular resistance, plasma volume expansión, increased cardiac output and plasma renin activity; la = prostacyclin, nitric oxide, kallikrein-kinin system, vasodilator arm of the renin angiotensin system, vascular endothelial growth factor (vegf). a possible role of vasodilators in the crucial process of trophoblast invasión and uterine artery transformation is supported. the relevance ofan adequate adaptation to pregnancy is highlighted not only by the intragestational complications derivedfrom a defective process, such as intrauterine growth restriction, preterm birth, and preeclampsia -its foremost expression- but also by the long term cardiovascular complications ofthe mother and her offspring.
El lugar que habita el padre en Chile contemporáneo. Estudio de las representaciones sobre la paternidad en distintos grupos sociales
Ximena Valdés S.
Polis : Revista de la Universidad Bolivariana , 2009,
Abstract: Frente a un proceso histórico de larga data inscrito en las transformaciones de la familia, el final del siglo pasado ha visto declinar la autoridad paterna propia de la matriz familiar patriarcal y moderno-industrial, abriendo un nuevo lugar al padre. Sobre la base de treinta entrevistas, este artículo analiza los cambios en las representaciones de la paternidad en distintos grupos sociales chilenos, las rupturas intergeneracionales y los modelos de paternidad contemporáneos, poniendo en evidencia los límites del cambio del orden de género tradicional aunque los padres actuales se muestren más involucrados y cercanos a sus hijos en un contexto en que convive el padre moderno con el "amo" que gobierna la familia restaurando la tradición.

Abstract: This review analyses the changes in immunological tolerance, and the systemic and local hemodynamic changes observed along human pregnancy. To underscore the conceptual importance of tolerance and adaptation the background isprovided by the two main advocates ofthese ideas: Gandhi and Darwin. The cognate factors that determine immunological tolerance (IT), systemic (SA) and local adaptation (LA) are múltiple; IT = desensitisation to paternal antigens, absence of HLA-A, roles of HLA-G, natural killer cells and their receptors; SA = decreased vascular resistance, plasma volume expansión, increased cardiac output and plasma renin activity; LA = prostacyclin, nitric oxide, kallikrein-kinin system, vasodilator arm of the renin angiotensin system, vascular endothelial growth factor (VEGF). A possible role of vasodilators in the crucial process of trophoblast invasión and uterine artery transformation is supported. The relevance ofan adequate adaptation to pregnancy is highlighted not only by the intragestational complications derivedfrom a defective process, such as intrauterine growth restriction, preterm birth, and preeclampsia -its foremost expression- but also by the long term cardiovascular complications ofthe mother and her offspring.
