La Argentina y el mundo frente al bicentenario de la Revolución de Mayo : Las relaciones exteriores argentinas desde la secesión de España hasta la actualidad

The Argentina and the world from the bicentennial of the may revolution not intended to be a story acontecimental but a working analytical and interpretive on our insertion in the successive international scenarios forms, marked by a tension between the separatist schemes and inclusion to the dominant powers in the successive global scenarios since the 19th century. It is divided into three thematic nuclei: 1. birth, peak and end of the traditional Argentine foreign policy: the secondment to the British influence. (1810-1946); 2. External policies against instability and tension between the inclusion and autonomy (1946-1983); 3. The a recent model of foreign policy: the end of the tension between the inclusion and autonomy?)

Satellite-based daily lake areas in the Yangtze Basin, China, 2000-2011

The Yangtze River Basin downstream of China's Three Gorges Dam (TGD) (thereafter referred to as "downstream" basin) hosts the largest cluster of freshwater lakes in East Asia. These lakes are crucial water stocks to local biophysical environments and socioeconomic development. Existing studies document that individual lakes in this region have recently experienced dramatic changes under the context of enduring meteorological drought, continuous population growth, and extensive water regulation since TGD's initial impoundment (i.e., June, 2003). However, spatial and temporal patterns of lake dynamics across the complete downstream Yangtze basin remain poorly characterized. Using daily MODIS imagery and an advanced thematic mapping scheme, this study presents a comprehensive monitoring of area dynamics in the downstream lake system at a 10-day temporal resolution during 2000-2011. The studied lakes constitute ~76% (~11,400 km**2) of the total downstream lake area, including the entire +70 major lakes larger than 20 km**2. The results reveal a decadal net decline in lake inundation area across the downstream Yangtze Basin, with a cumulative decrease of 849 km**2 or 7.4% from 2000 to 2011. Despite an excessive precipitation anomaly in the year 2010, the decreasing trend was tested significant in all seasons. The most substantial decrease in the post-TGD period appears in fall (1.1%/yr), which intriguingly coincides with the TGD water storage season. Regional lake dynamics exhibit contrasting spatial patterns, manifested as evident decrease and increase of aggregated lake areas respectively within and beyond the Yangtze Plain. This contrast suggests a marked vulnerability of lakes in the Yangtze Plain, to not only local meteorological variability but also intensified human water regulations from both the upstream Yangtze main stem (e.g., the TGD) and tributaries (e.g., lakes/reservoirs beyond the Yangtze Plain). The produced lake mapping result and derived lake area dynamics across the downstream Yangtze Basin provides a crucial monitoring basis for continuous investigations of changing mechanisms in the Yangtze lake system.

Land Surface Temperature continuous time series from SSM/I passive microwave radiometers, over northern latitudes (Latitudes > 45°N), during summer snow free period (2000-2011), with links to NetCDF files

Remote sensing instruments are key players to map land surface temperature (LST) at large temporal and spatial scales. In this paper, we present how we combine passive microwave and thermal infrared data to estimate LST during summer snow-free periods over northern high latitudes. The methodology is based on the SSM/I-SSMIS 37 GHz measurements at both vertical and horizontal polarizations on a 25 km × 25 km grid size. LST is retrieved from brightness temperatures introducing an empirical linear relationship between emissivities at both polarizations as described in Royer and Poirier (2010). This relationship is calibrated at pixel scale, using cloud-free independent LST data from MODIS instruments. The SSM/I-SSMIS and MODIS data are synchronized by fitting a diurnal cycle model built on skin temperature reanalysis provided by the European Centre for Medium-Range Weather Forecasts (ECMWF). The resulting temperature dataset is provided at 25 km scale and at an hourly time step during the ten-year analysis period (2000-2011). This new product was locally evaluated at five experimental sites of the EU-PAGE21 project against air temperature measurements and meteorological model reanalysis, and compared to the MODIS LST product at both local and circumpolar scale. The results giving a mean RMSE of the order of 2.2 K demonstrate the usefulness of the microwave product, which is unaffected by clouds as opposed to thermal infrared products and offers a better resolution compared to model reanalysis.

Attitudes towards disability in education through the SSCI (2000-2011): a topical and bibliometric analysis

Introduction. The purpose of this study is to describe and characterize the international sci-entific output relating to “attitudes towards disability in education”, using a battery of bibliometric indicators that make it possible to analyze and monitor international scientific activity. Method. This ex post facto retrospective study analyzed 925 papers published in the Social Sciences Citation Index (SSCI) database during the period 2000-2011. Results. The number of publications increased steadily between 2006 and 2010. The results reported here include the most productive authors, the journals that deal with this topic, and the articles cited most often. An analysis of research types showed a tendency toward empiri-cal studies. A total of 18 categories were identified when considering article content, and the distribution of the research studies across stages of education was found to be uneven. Discussion and Conclusion. The results reveal a topic that is highly current in today’s scien-tific community, and offer us a view of the traits that have characterized research on "attitudes towards disability in education" for the last eleven years.

Recepción, audiencias y consumo cultural en Venezuela (período: 2000-2011)

Analizamos el estado del arte de los estudios de recepción, audiencias y consumo cultural en Venezuela durante el período 2000-2011. Examinamos enfoques teóricos sobre el campo de la recepción mediática y cultural, desde las propuestas conceptuales de Aguirre, Barrios y Hernández Díaz. Se pudo constatar, en esta revisión documental, que los estudios de recepción en Venezuela abordan cuatro campos de estudio: 1) Educación para la recepción. 2) Influencia de la televisión. 3) Ciber-recepción. 4) Consumo cultural.

Familia y discapacidad intelectual: un estudio bibliométrico de 2000-2011 a través del Social Science Citation Index

El objetivo de este estudio fue realizar un análisis bibliométrico de la producción científica publicada entre el año 2000 y 2011 sobre familia y discapacidad intelectual, con la finalidad de ofrecer una descripción global del estado actual de la investigación en dicho ámbito. La base de datos empleada ha sido Social Science Citation lndex extrayendo una muestra de 952 artículos. Fueron analizados el año de publicación, las revistas, el índice de autoría, las temáticas, el tipo de investigación, las citas y el idioma. A por1ir de los resultados, se observó una periodicidad estable en cuanto a los indicadores de producción y una identificación de temáticas que mantienen una relación con la realidad social y las necesidades que envuelve este campo de conocimiento. El presente trabajo permite conocer la evolución que ha seguido el estudio de la familia y la discapacidad intelectual en el periodo temporal indicado y ofrece un amplio conocimiento sobre las investigaciones realizadas al respecto.
