Wavelet analysis of the ionospheric response at mid-latitudes during the April 200 storm using magnetograms and vTEC from GPS

In this work we pursue the idea of computing a parameter that allows us to estimate the local ionospheric response to a geospheric event that triggers an ionospheric storm. For that, wavelet technique has been chosen because of its ability to analyze non-stationary signals. The advantage of the time-frequency analysis method called Wavelet Transform resides in providing information not only about the frequencies of the event but also about its location in the time series. Specifically, we compute the Scale Average Wavelet Power (SAWP) of two parameters that describe the local geomagnetic field variation at the Earth surface caused by a geospheric storm and ionospheric response to the storm event. In particular, we propose the time delay between the maximum values of SAWP applied to the vTEC (vertical Total Electron Content) and the horizontal component of the geomagnetic field (H) variations as parameters to characterize the local behavior of the ionospheric storm. We applied the parameter to the geomagnetic and ionospheric disturbances caused by a coronal mass ejection (CME) that took place on April 4, 2000. We used vTEC values computed from GPS observations and H at the surface of the Earth, measured in stations near to each GPS station chosen. The vTEC values used came from the GPS permanent stations belonging to the global IGS (International GNSS Service) network. We chose stations located at magnetic mid-latitudes. Moreover, three-longitude bands representing the ionospheric behavior at different local times (LT) were studied. Because the April 2000 storm has been extensively studied for many authors, the results are compared with those in the literature and we found a very good agreement as expected.En este trabajo perseguimos la idea de estimar un parámetro que nos permita calcular la respuesta ionosférica local a un evento geosférico desencadenante de una tormenta ionosférica. Para ello, se eligió la aplicación de la técnica ondeleta debido a su capacidad para analizar señales no estacionarias. La ventaja del método de análisis en tiempo y frecuencia llamada Transformada Ondeleta reside en el hecho de que provee información, no sólo acerca de las frecuencias del evento, sino también sobre su ubicación en la serie de tiempo. En concreto, se calcula el promedio por escalas de la potencia de la transformada ondeleta (SWAP, de su sigla en inglés Scale Average Wavelet Power) para dos parámetros que describen la respuesta local de la magnetosfera y la ionosfera a una tormenta. En particular, se propone el retraso de tiempo entre los valores máximos de SAWP aplicadas al vTEC (Contenido Electrónico Total en dirección Vertical) y la componente horizontal del campo geomagnético (H), como parámetros cuyas variaciones caracterizan el comportamiento local de la tormenta ionosférica. El parámetro propuesto se aplicó a las perturbaciones geomagnética e ionosférica causadas por una eyección de masa coronal (CME, Coronal Mass Ejection), que tuvo lugar el 4 de abril de 2000. Se utilizaron valores vTEC calculados a partir de las observaciones GPS y H en la superficie de la Tierra, medida en las estaciones cercanas a cada estación de GPS elegida. Los valores de vTEC utilizados provinieron de las estaciones GPS permanentes que pertenecen a la red del servicio internacional IGS (International GNSS Service). Entre todas, elegimos estaciones situadas en latitudes magnéticas medias. Por otra parte, estudiamos tres bandas de longitud que representan el comportamiento de la ionosfera a distintas horas locales (LT). Debido a que la tormenta de abril de 2000 ha sido ampliamente estudiada por muchos autores, los resultados se comparan con los de la literatura y nos encontramos con un muy buen acuerdo entre los datos publicados y nuestros resultados, tal y como se esperaba.Fil: Fernandez, Laura Isabel.

Parental Support of Latinos in Higher Education

Many universities grapple with Latino student retention issues. Latinos are the largest and fastest-growing ethnic group in the United States, yet they also are the group that has the least amount of formal education. The literature suggests that parental support helps Latinos succeed academically in elementary, middle, and high schools. However, there has been little research on how or even whether Latino parental support influences academic success at the postsecondary level. Consequently, there is a lack of knowledge about (a) Latino parental behavior and attitudes during the years their children attend college and (b) the relationship between parents\u27 behavior and attitudes, on the one hand, and Latino college student academic achievement and retention, on the other. This study provides information about the role parental support plays in promoting the academic success and retention of Latino students in higher education. Central to this study is qualitative analysis of Latino parent narratives which focus on how parents feel about their children attending college, the impact that college attendance has on their child and the family, and the support they provide their children as they navigate the academic environment. The study also gathered data about parental perceptions of how the University supports—or fails to support—their children while in school, and how these perceptions impacted parents\u27 support efforts and strategies. A case study/cross-case analysis design was used in the study. Parent participants were randomly selected from the parents of students who participate in the Educational Opportunity Program at a public four-year Hispanic Serving Institution. Findings suggest that Latino parents support their children in non-traditional ways. For example, they used, often quite consciously, public expressions of pride in their children\u27s accomplishments to demonstrate support and motivate their children; also promoted self-respect and respect for others as foundational, ingrained values that they believed helped their children navigate through the challenges of university life. Parents also indicated that, in contrast to their direct involvement with schools in the K-12 years, they found few opportunities to be involved with the university. Still, they trusted the university to provide the sort of help that their children required

Annual and semiannual variations of vertical total electron content during high solar activity based on GPS observations

Annual, semiannual and seasonal variations of theVertical Total Electron Content (VTEC) have been investigatedduring high solar activity in 2000. In this work we useGlobal IGS VTEC maps and Principal Component Analysisto study spatial and temporal ionospheric variability. The behaviorof VTEC variations at two-hour periods, at noon andat night is analyzed. Particular characteristics associated witheach period and the geomagnetic regions are highlighted.The variations at night are smaller than those obtained atnoon. At noon it is possible to see patterns of the seasonalvariation at high latitude, and patterns of the semiannualanomaly at low latitudes with a slow decrease towards midlatitudes. At night there is no evidence of seasonal or annualanomaly for any region, but it was possible to see the semiannualanomaly at low latitudes with a sudden decrease towardsmid latitudes. In general, the semiannual behavior showsMarch–April equinox at least 40% higher than Septemberone. Similarities and differences are analyzed also with regardto the same analysis done for a period of low solar activity.Fil: Natali, Maria Paula. Universidad Nacional de La Plata.
