Application of the Cross Wavelet Transform to Solar Activity and Major Earthquakes Occurred in Chile  [PDF]
Patricia Alejandra Larocca
International Journal of Geosciences (IJG) , 2016, DOI: 10.4236/ijg.2016.711095
Abstract: Historical earthquakes registered in Chile (from 1900 up to 2015) with epicenters located between 17?30'S and 56?0'S latitude and yearly mean total sunspot number have been considered in order to evaluate a significant linkage between them. The occurrence of strong earthquakes along Chile and the sunspots activity are analyzed to inspect possible influence of solar cycles on earthquakes. The cross wavelet transform and wavelet coherence analysis were applied for sequences of sunspots and earthquakes activity. An 8 - 12 years modulation of earthquakes activity has been identified.
Períodos perturbados: disipación de energía y corrientes geomagnéticas inducidas
Larocca,Patricia A.; Silbergleit,Virginia M.;
Geoacta , 2010,
Abstract: in a typical event (12-13 june 2005), solar wind energy rate and total energy dissipation rate in the magnetosphere (e and ut respectively) and increased induced currents in a gas pipe located in the auroral zone are studied. for the period geomagnetic indices ae and dst, and the bz component of the interplanetary geomagnetic field are analyzed as indicators of the development of the troubled period. ring current decay times are calculated using different approaches in accordance with the phases of the storm. during this period there were significant geomagnetic variations due to geomagnetic substorms and induced currents on the pipeline located in the otawa river valley, this fact could produce corrosion increases in its structure.
Períodos perturbados: disipación de energía y corrientes geomagnéticas inducidas

Abstract: Se estudia, en un evento típico (12-13 de junio de 2005) las energías entrante y disipada en la magnetosfera ( y Ut respectivamente) y el aumento de corrientes inducidas en un gasoducto ubicado en altas latitudes. Se analizan para el período citado los índices geomagnéticos AE y Dst, y la componente Bz del campo geomagnético interplanetario como indicadores del desarrollo del período perturbado. Se calculan los tiempos de decaimiento del anillo de corriente utilizando distintas aproximaciones de acuerdo con las fases de la tormenta. Durante este período se observaron variaciones geomagnéticas importantes que originaron corrientes geomagnéticas inducidas significativas sobre el gasoducto de la empresa Transcanada ubicado en la zona del valle del río Ottawa; pudiendo ser afectada la vida útil del mismo.

Multitud o exclusión: El necesario debate en torno a las consecuencias de las transformaciones en el mundo del trabajo
Collado,Patricia Alejandra;
Estudios de filosof?-a pr??ctica e historia de las ideas , 2006,
Abstract: the transformations in the labor world, due to changes in global capital, have given way to a range of opinions over the new characteristics taken on by the 'social question'. analyzing -from a social sciences point of view- the different ways the effects of these recent changes are being characterized, gives way to two categories that take on a new meaning in the current context: multitude and exclusion. in this work, the potentials and restrictions of these categories are considered to bring to light their critical and explicatory potential in relation to the wide-ranging and pres sing issues that are tearing the social fabric in this unique historic moment.
El arte de amar de Ovidio: una lectura sociocrítica
Calvelo,Patricia Alejandra;
Cuadernos de la Facultad de Humanidades y Ciencias Sociales. Universidad Nacional de Jujuy , 2001,
Abstract: in the present work, that is fitted within the general frame of the studies of sort, i carry out a reading of love the ars poem of publio ovid nasón (s. i a.c.) using the contributions of the sociocrítica, and i make a boarding of the text from the methodology of the semiótica of statements. to the effects of the analysis that i carry out in these pages, the sociocrítica contributes the fundamental approach. this theoretical field sets out to discover how the social thing in texts registers. said of other words, its purpose consists of the search of the forms of joint between two systems: textual and the social one. in this study in individual, i set out to recognize ideologemas present in the mentioned ovidiano poem. for it, i follow the concept of ideologema of edmond cros, that defines it as a "semio'tico-ideological microsystem that sublies in a functional and significant unit of the speech" (lexía). the components of this microsystem are semas and the social values, that fluctuate according to the historical circumstances. two hypotheses - first, of theoretical nature, and second, of methodologic order they guide my work: 1. in love ars of ovid, the words dominate (that normally had to make reference to the "owner", the roman housewife) and virtus constitutes ideologemas inasmuch as they work like enunciation places in where new semantic contents and social values are generated and found, establishing therefore the historical-social coordinates of the text. 2. ideologemas can identify by means of the contextual definitions, instrument forged by the semiótica de enunciados. the methodology of the semiótica de enunciados contributes to a series of analytical operations that work indeed on the saying, which allows to recover the positive meaning which they are attributed to the terms based on the material context and in that they appear. the conclusions to which arrival allows me to confirm that it is the indicated methodology to recognize ideologemas. the main co
Visibilidad e invisibilidad: Acerca del trabajo y las mujeres
Collado, Patricia Alejandra;
Revista Katálysis , 2009, DOI: 10.1590/S1414-49802009000200007
Abstract: the crisis of employment, combined with theories about the end of work, place labor at the center of the agenda. given this situation, it is found that debates around labor in general (its productive and reproductive spheres), its relation with employment and the visible and invisible forms of conducting work have been approached by one of the most neglected traditions of social thinking: feminism. feminist thinkers have questioned the meaning of work and non-work in relation to the constant increase of the participation of women in the labor market. although feminist proposals have different levels of analysis and emphasis, it is necessary to return to their unique production, in order to unveil the situation of greater exploitation and oppression, of workers in general and in particular of women. this situation is facilitated by the apparent "invisibilization" or by the loss of the centrality of labor.

Constructing Pedagogical Models For E-learning
Patricia Alejandra Behar
International Journal of Advanced Corporate Learning (iJAC) , 2011, DOI: 10.3991/ijac.v4i3.1713
Abstract: This article brings forth an overview of the paradigmatic crisis and the introduction of new pedagogical practices. It also discusses the relationship between paradigm and pedagogical model, presenting a theoretical discussion on the concepts of pedagogical model for E-learning and its pedagogical architecture. To do so, the elements that are part of it such as organizational aspects, content, methodological and technological aspects are discussed. This theoretical discussion underlies the construction of a new pedagogical model for E-learning taking into account the grounds over which today′s net society is based on: time and space. Examples of E-learning pedagogical models are presented.
Desventuras de la evaluación en Etnomatemática
Alejandra Santillán,Patricia Zachman
Revista Latinoamericana de Etnomatemática , 2008,
Abstract: La evaluación se define como un proceso para obtener información sobre el aprendizaje, formular juicios y tomar decisiones. En la actualidad, no hay separación estricta entre las actividades de aprendizaje y las de evaluación Las estrategias evaluativas influyen tanto en la formación del pensamiento y las actitudes como enla autoestima del individuo evaluado.Si desde la etnomatemática, la ense anza de la matemática es un proceso de enculturación cuyo objetivo es facilitar que los alumnos se apropien de una parte específica de su cultura: cómo se evalúan dichas prácticas?, con qué parámetros? el conocimiento etnomatemático, es evaluable?Esta investigación aborda dos posturas con respecto a la formulación de juicios sobre la etnomatemática: la evaluación y la validación del conocimiento etnomatemático.
Una experiencia de capacitación en Etnomatemática
Alejandra Santillán,Patricia Zachman
Revista Latinoamericana de Etnomatemática , 2009,
Abstract: El presente trabajo describe las experiencias de capacitación, llevadas a cabo en la ciudad de Pdcia R. Sáenz Pe a, provincia del Chaco (Rep. Argentina), en el marco del Programa de Actualización y Perfeccionamiento 2008 en servicio a los docentes de la provincia en el nivel medio y superior. Mediante la documentación narrativa se pretende compartir tiempos, espacios y recursos para que los colegas puedan compartir con las autoras lo que pasa y pasó en ellos cuando tuvieron un primer acercamiento académico con la etnomatemática. La propuesta apunta amalgamar ense anza con investigación, aproximándose hasta el punto de delinear un modelo de ense anza cuya base fundamental es la investigación, que nutre a la acción y ayudaa los profesores a teorizar acerca de su ense anza.
