Statistical Prediction of Wet and Dry Periods in theComahue Region (Argentina)  [PDF]
Marcela H. González, Diana Dominguez
Atmospheric and Climate Sciences (ACS) , 2012, DOI: 10.4236/acs.2012.21004
Abstract: General features of rainy season with excess or deficits are analyzed using standardized precipitation index (SPI) in Limay and Neuquen River basins. Results indicate that most of dry and wet periods persist less than three months in both basins. Furthermore, an increase of rainfall variability over time is observed in the Limay river basin but it is not detected in the Neuquen river basin. There is a tendency for wet (dry) periods to take place in El Ni?o (La Ni?a) years in both basins. Rainfall in both basins, have an important annual cycle with its maximum in winter. In addition, possible causes of extreme rainy seasons over the Limay River Basin are detailed. The main result is that the behavior of low level precipitation systems displacing over the Pacific Ocean in April influences the general hydric situation during the whole rainy season. In order to establish the existence of previous circulation patterns associated with interannual SPI variability, the composite fields of wet and dry years are compared. The result is that rainfall is related to El Ni?o- Southern Oscillation (ENSO) phenomenon and circulation over the Pacific Ocean. The prediction scheme, using multiple linear regressions, showed that 46% of the SPI variance can be explained by this model. The scheme was validated by using a cross-validation method, and significant correlations are detected between observed and forecast SPI. A polynomial model is used and it little improved the linear one, explaining the 49% of the SPI variance. The analysis shows that circulation indicators are useful to predict winter rainfall behavior.

LA AGENCIA DE LA NI A Y EL NI O EN LA CONDICIóN PRE-CIUDADANA AGENCY (CHILDHOOD IN THE PRE-CITIZEN CONDITION)
González Coto, Marcela
Revista Electrónica Actualidades Investigativas en Educación , 2012,
Abstract: Resumen: El presente ensayo se deriva del trabajo que recientemente han desarrollado la Fundación PANIAMOR y la Dirección General del Programa CEN-CINAI del Ministerio de Salud, sobre la formación ciudadana de los ni os y las ni as costarricenses en la primera infancia. Las acciones conjuntas se han enfocado en la capacidad de agencia de los ni os y las ni as, entendida como la disposición para explorar, reflexionar, actuar y valorarse en sus entornos como sujetos políticos. Para este fin, en este ensayo se lleva a cabo un análisis crítico de los modelos ideológicos y culturales que, en la sociedad contemporánea, legitiman y fomentan la condición de “pre-ciudadanía” de la infancia, mermando su desempe o, presente y futuro, como ciudadanos plenos de la sociedad. El análisis se sustenta en materiales diversos, de distintos orígenes, todos relativos a las condiciones actuales de la infancia y las formas como se restringen estas capacidades de agencia. El ensayo también aborda las dificultades y obstáculos que enfrenta un replanteamiento de las relaciones entre adultos y ni os. También se documentan los esfuerzos recientes, tanto locales como internacionales, para crear marcos alternativos desde los cuales replantear la relación institucional entre unos y otros. Como principal resultado del ensayo, se delinean un conjunto de directrices, con expresión curricular, que pueden sustentar el desarrollo de las capacidades de agencia infantil con una manifestación directa en la ni ez ciudadana, la cual, se plantea, se articula en tres dimensiones o ejes de desarrollo (la responsabilidad, la autonomía y el pensamiento complejo).Abstract: This essay is derived from the works that have recently developed the PANIAMOR Foundation and the General Board of Directors of the CEN-CINAI Program of the National Ministry of Health, on the civic education of Costa Rican children in early childhood. Joint activities have focused on the ability of agency to children in this age, understood as a willingness to explore, reflect, act and valued in their environments as political subjects. For this goal, this paper conducts a critical analysis of the ideological and cultural models, in the contemporary society, that legitimize and promote the status of "pre-citizens" of the children, diminishing their performance, present and future, as full citizens of their society. The analysis is based on different materials from distinct origins, all relating to the current conditions of childhood and the ways in which these capabilities are diminished. The essay also discusses the difficulties

Trabajando contra la violencia de sexo/género
Marcela González-Barrientos
Boletín Científico Sapiens Research , 2011,
Abstract: The article proposes to reflect on the sex/gender violence problem from a feminist psychoanalytic perspective revealing and heightening the significant dissemination, ie, the work with words, it tries to deconstruct the gender's notions from a political dimension and historicize the regulations of hegemonic thinking, favoring the femininity approach from the sexual difference issue point of view. This approach allows the expansion of the possible meanings and their visibility beyond the discourse, what's not said operates in a decisive matter constructing subjectivities, even more so when it comes to strengthening the control of one sex over the other. In this context, the text begins by addressing the importance of the denomination under which each country places the gender violence problem, revealing concepts that are to be reinforced with the name and which underlie to such designation. So forth, it discusses the theoretical path, clinical and political work against violence, carried out by a renowned Chilean feminist institution that allows us to extract reflections, lessons and most of all new questions to think about a clinic for the difference. Finally, some recent government initiatives have been criticized, such as the femicide integration and visibility as a statistical indicator of such problem and creation of treatment centers for men accused of violence against women, an ambitious project that opens us to reflect on the quality of love between men and women.

Abstract: El objetivo del presente estudio es detectar indicadores de circulación que se relacionen con la variabilidad interanual de la lluvia en la llanura chaquena. La precipitación media en regiones definidas se correlacionó con la temperatura de la superficie del mar, altura geopotencial en 1000, 500 y 200 Hpa, presión a nivel del mar, humedad específica en 925Hpa, viento zonal y meridional en 850 Hpa, simultáneamente y en el mes previo. El aumento de la precipitación estival se asocia al debilitamiento del anticiclón del Atlántico y altos valores de humedad específica en el noreste de Argentina. En la región noreste además se asocia a viento este y debilitamiento del viento del norte mientras que la región noroeste es la más influenciada por La Nina. En primavera el rasgo fundamental es la relación en el noreste con la fase cálida del ENOS. El rasgo más importante es que se asocia la precipitación estival en las tres subregiones con el debilitamiento del anticiclón del Atlántico durante el mes previo mientras que en la primavera la senal más importante se relaciona con el ENOS.
