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 HISTORIA Y LAS RELACIONES INTERNACIONALES: DE LA HISTORIA INTERNACIONAL A LA HISTORIA GLOBAL
rojas,diana marcela;
Historia Crítica , 2004,
Abstract: in exploring the connections between international relations and history, we find a link that contributes to the redefinition of the discipline itself. in fact, international relations as a rational discourse on one aspect of the social sphere constitutes a historical object in itself. the aim of the article is to sitúate ir on its historical voyage in order to identify the development of three different international-system models throughout the course of the past three centuries. this overview leads us from a history between nations to a world history and, finally, to a global history, the nature of which allows us to outline certain coordinates in the international scenario at the dawn of the 21st century and indicate the elements that make the international idea lose its specificity and confronts us with the challenge of reformulating our own understanding of today's world.

La Falla Estatal Y La Globalización
Rojas,Diana Marcela;
Análisis Político , 2007,
Abstract: state failure, more than a simple "anomaly" in the international system, reveals a deep transformation of statehood under the influence of globalization process. the so called "failed", "collapsed" or "unviable states" correspond only to the most extreme cases of a spectrum in which the limits of statehood "normality" turn out to be difficult to define and the modern concept of state-nation shows its inadequacy regarding the changes in the contemporary state. therefore the need of a theory that comprises the model or models of statehood that would be in formation under this new global order.

La Falla Estatal Y La Globalización State Failure And Globalization
Diana Marcela Rojas
Análisis Político , 2007,
Abstract: La falla estatal, más que una simple "anomalía" en el sistema internacional, revela una profunda transformación de la estatalidad bajo el influjo del proceso de globalización. Los llamados "estados fallidos", "colapsados" o "inviables" corresponden sólo a los casos más extremos de un espectro en el que los límites de la "normalidad" estatal resultan difíciles de fijar y el concepto moderno de estado-nación muestra su inadecuación frente a los cambios en el estado contemporáneo; de allí la necesidad de una teoría que dé cuenta del modelo o los modelos de estatalidad que se estarían configurando bajo este nuevo orden global. State failure, more than a simple "anomaly" in the international system, reveals a deep transformation of statehood under the influence of globalization process. The so called "failed", "collapsed" or "unviable states" correspond only to the most extreme cases of a spectrum in which the limits of statehood "normality" turn out to be difficult to define and the modern concept of state-nation shows its inadequacy regarding the changes in the contemporary state. Therefore the need of a theory that comprises the model or models of statehood that would be in formation under this new global order.
