¿Estás nervioso? Las elecciones desde una villa del Gran Buenos Aires

En este artículo pretendo explorar la política en el Gran Buenos Aires a partir de un análisis de las elecciones legislativas de 2009 desde mi etnografía en una villa de La Matanza en proceso de urbanización. A partir de allí, intentaré dar cuenta de una serie de perspectivas que quedan opacadas en los análisis centrados en procesos electorales. Mientras éstos enfocan hacia las estrate-gias de campaña de los candidatos y los entramados políticos desde los cuales construyen apoyos para explicar los resultados electorales (o intentar predecir-los), el punto central de este artículo consiste en mostrar cómo las elecciones se imponen y son apropiadas localmente a partir de una perspectiva centrada en la urbanización de la villa.The purpose of this paper is to explore Great Buenos Aires's politics analyzing midterm elections (2009) from my ethnography in a shantytown of La Matanza under a process of urbanization. I will try to show some outlooks which are usually darkened by electoral analyses. While these researches usually focus on campaign strategies and political networks in order to explain (or predict) electoral results, the main contribution of this paper is to show how elections are generally imposed and locally appropriated from a local perspective oriented towards the urbanization of the shantytown

Wavelet Analysis of Coherent Structures Above Maize and Soybean Crops

Turbulent coherent structures developed in the atmospheric surface layer are responsible for a large part of momentum and scalar fluxes exchanged with canopy layers. Their participation in processes such as evapotranspiration, pathogen infections, mechanical damage due to wind gustiness, modifies crop yield, with generally negative effects. Although South America has a variety of land covers, studies of these subjects are not common in the region. Here, we characterize the time scales of turbulent coherent structures above extensive maize and soybean crops using the wavelet methodology. The role of canopy-height changes associated with crop growth on turbulent structures development is analyzed. The effect of atmospheric stability on the characteristics of the structures detected is also studied. Wavelet analysis shows that both momentum and sensible heat are transported mostly by eddies of 350–400 s periods and also by more intense eddies of 40–50 s period. For momentum fluxes, the former period range prevails under strongly unstable conditions, while the second is present mostly under near-neutral situations. On the contrary, 40–50 s-lasting structures dominate the sensible heat transport under free convection conditions, while longer-lasting eddies transport heat in near-neutral conditions. Stability is the main factor allowing the coherent-structure topological classification, while the crop height is not important. Structures are identified through measurements performed at relative heights greater than those usually discussed in the literature, which indicates the need for further research into coherent-structure modelling.Fil: Curto, Lucia.

Actual evapotranspiration and the pattern of soil water extraction of a soybean (Glycine max) crop

Crop evapotranspiration knowledge during different phenological stages helps determine crop water requirements and water use efficiency. This study was intended to estimate evapotranspiration of soybean grown under field conditions using the water balance equation and to characterize root water extraction across different soil layers analyzing daily values of its availability. In order to estimate the crop daily water consumption, temporal and spatial variability (vertical) of soil water content up to a depth of 1.10 m was investigated. At the beginning of the experiment, measurements showed that the soybean crop extracted water from the upper levels, and as it continued to grow, water uptake at deeper levels increased. The highest water uptake occurred during reproductive growth stages, which matched the period of highest atmospheric demand. The crop showed a better response to atmospheric demand under water availability, whereas under stress conditions, both evapotranspiration and soil water content decreased.Crop evapotranspiration knowledge during different phenological stages helps determine crop water requirements and water use efficiency.

Evapotranspiración real y patrones de extracción de agua del suelo de un cultivo de soja (Glycine max)

Conocer la evapotranspiración de un cultivo durante sus distintos estadios fenológicos ayuda a determinar los requerimientos de agua del mismo y la eficiencia del uso de agua. Los objetivos de este trabajo fueron estimar la evapotranspiración de un cultivo de soja desarrollado bajo condiciones de campo, utilizando la ecuación de balance hídrico, y caracterizar la extracción de agua por parte de las raíces en las distintas capas del suelo, analizando los valores diarios de su disponibilidad. Para determinar los consumos diarios del cultivo se estudió la variabilidad temporal y vertical del contenido de agua en el suelo hasta 1.10 m de profundidad. Al comienzo de las mediciones, el cultivo de soja extrajo agua de los niveles superiores, y a medida que se desarrollaba, aumentó el consumo en niveles más profundos. El mayor consumo de las plantas se dio en los estadios reproductivos, coincidiendo con el período de mayor demanda atmosférica. El cultivo mostró una mejor respuesta a la demanda atmosférica bajo la disponibilidad de agua, mientras que, en condiciones de estrés, tanto la evapotranspiración como el contenido de agua en el suelo disminuyeron.Crop evapotranspiration knowledge during different phenological stages helps determine crop water requirements and water use efficiency.

Estudio de las diferencias de adquisición del español en adultos emigrantes búlgaros en Valladolid

La adquisición de segundas lenguas (L2) es un proceso cognitivo por el que un hablante aprende y usa de manera continuada una lengua distinta a la materna. Los diferentes niveles de aprendizaje son los estadios de interlengua o protolenguaje, que suponen una simplificación lingüística de las marcas formales de las lenguas naturales humanas. En la adquisición de L2, superar el nivel del protolenguaje y adquirir la lengua natural dependerá de los siguientes factores. Primeramente, el cierre del periodo crítico, que afecta eminentemente a la adquisición de la primera lengua (L1), dificulta la adquisición natural e inconsciente de la L2. La edad de inicio de aprendizaje de la L2 hace que cuanto antes se aprenda la lengua, haya más probabilidades de adquirirla completamente. Finalmente, el entorno y las relaciones sociales incentivan el uso de la L2, y la intención comunicativa propicia el uso de estrategias comunicativas y expresivas en la L2.Second language acquisition (L2) is a cognitive process by which a speaker learns and uses continuously a language other than the mother tongue. The different levels of learning are the stages of interlanguage or protolanguage, which entails a linguistic simplification of the formal marks of the natural human languages. In L2 acquisition, surpassing the level of protolanguage and acquiring the natural language will depend on the following factors. Firstly, the closure of the critical period, which eminently affects the acquisition of the first language (L1), hinders the natural and unconscious acquisition of L2. The age of onset of L2 learning means that the earlier the language is learned, the more likely it is to acquire it completely. Finally, the environment and social relations encourage the useDepartamento de Lengua EspañolaGrado en Español: Lengua y Literatur
