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.

Arbeláez,Juan Camilo; Franco,Luis Ceferino; Betancur,César; Murillo,Juan Guillermo; Gallego,Paula Andrea; Henao,Viviana María; Londo?o,Johana Andrea; Mejía,Claudia Marcela; Palacio,Diana Marcela; Salazar,Elizabeth; Salazar,Luisa Fernanda; Valderrama,Natalia; Varela,Diana Carolina;

Abstract: its main objective is to succinctly present a description of the models considered the most relevant in the wide range of possibilities for the quantification of operational risk. the article is structured in the following form: first it briefly contextualizes operational risk in the frame of financial risks in general, and in the frame of the current regulations world-wide. in the following section the basic models (basic indicator approach, indicator standard approach and alternative standard approach) proposed for the quantification of the operational risk are described. then it describes the minimum general, qualitative and quantitative requirements, in the light of the new basilea agreement, that should be met by the advanced measurement approach that financial organizations try to submit to approval of the regulating institutions. later, it shows some recent specific local and world-wide studies and finally some conclusions are obtained.
Cooperativismo de trabajo asociado y estrategia: Revisión de literatura
Bustamante Salazar,Alina Marcela;
Pensamiento & Gestión , 2009,
Abstract: cooperativism and strategy have been in recent days important topics in the academy and at research level. cooperativism is an alternative model that aims at the organization of production and work. strategy, on the other hand, is a study and practical field, whose understanding depends on the characteristics of the people who study and define them. this paper follows the hafsi, séguin and toulousse's strategy model in order to explain how this topic has been understood in submitted articles about worker's cooperatives, through literature review in academy journals in cooperativism and management.
Cooperativismo de trabajo asociado y estrategia: Revisión de literatura The associated working cooperativism and strategy: Literature review
Alina Marcela Bustamante Salazar
Pensamiento & Gestión , 2009,
Abstract: Cooperativismo y estrategia han sido, en el curso de las últimas décadas, asuntos de interés en el plano académico e investigativo. El primero constituye un modelo alternativo de organización de la producción y el trabajo; la segunda, un campo de estudio y de práctica, cuya comprensión varía de acuerdo con la concepción de la empresa, el modelo de negocio y las características situacionales de quienes las definen y las estudian. Siguiendo el modelo propuesto por Hafsi, Séguin y Toulousse (2000), este documento se propone explicar cómo ha sido comprendida la estrategia en los artículos publicados sobre cooperativas de trabajo asociado, a partir de la revisión de literatura en revistas académicas especializadas en gestión y cooperativismo. Cooperativism and strategy have been in recent days important topics in the academy and at research level. Cooperativism is an alternative model that aims at the organization of production and work. Strategy, on the other hand, is a study and practical field, whose understanding depends on the characteristics of the people who study and define them. This paper follows the Hafsi, Séguin and Toulousse's strategy model in order to explain how this topic has been understood in submitted articles about worker's cooperatives, through literature review in academy journals in cooperativism and management.

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.
