VALIDACIóN DE LA ESCALA DE EXPRESIVIDAD EMOCIONAL EN UNA MUESTRA DE UNIVERSITARIOS ARGENTINOS
Piemontesi,Sebastián Eduardo;
Suma Psicológica , 2012,
Abstract: emotional expressivity, defined as the ability to express emotional states in observable behaviors, is essential for individuals healthy functioning, and was positively associated with wellbeing, self-esteem, life satisfaction and negativelyrelated with diseases such as schizophrenia, depression, personality disordersand post traumatic stress disorder. to answer the need for an instrument which can evaluate this construct in a valid and reliable manner, this study explored the psychometric properties of the emotional expressivity scale adapted into spanish. for this reason, an exploratory factor analysis replicating the one-dimension solution was performed, a coefficient alpha of .94 was obtained, gender differences with higher scores in women, and test-retest coefficients for a 4-week interval with values of .88 in women and .86 in men. additionally, confirmatory factor analyzes were performed separately for each gender obtaining appropriate values for all fit indices, but not in men. finally the results, scope and limitations of this paper are discussed.

Processes in Social Cognitive and Affective Neuroscience to Social Understanding and Interaction: An Integrative Framework.
Piemontesi, Sebastián Eduardo
Revista Argentina de Ciencias del Comportamiento , 2010,
Abstract: This review aims to provide an integrating framework of the basic processes studied by the Social Cognitive and Affective Neuroscience that are involved in the ability of people to understand and interact with others. For this, are reviewed the main findings about cognitive, social and emotional processes, by indicating the brain areas where they are located, and are analyzed according if are automatic or controlled processes, if they focus on internal or external characteristics of individuals, and if they are simple or complex processes. This article proposes a functional-anatomic distribution where automatic and controlled processes are located on ventral and dorsal areas respectively, externally and internally focused processes in lateral and medial areas, respectively, and simple and complex processes in the caudal and rostral areas respectively. Finally, limitations and future directions of research are discussed.
Psychometric properties of the revised Spanish version of the German test anxiety inventory (GTAI-AR) in Argentinean university students [Propiedades psicométricas de la versión en espa ol revisada del inventario alemán de ansiedad ante exámenes (GTAI-AR) en universitarios argentinos]

Universitas Psychologica , 2012,
Abstract: In the present study was evaluated the psychometric properties of the Spanish version of the German Test Anxiety Inventory in argentinean university students. Was conducted an exploratory and confirmatory factor analysis using items parcels. Was evaluated the fit of three possible models according to the theoretical background, one that supports the unidimensionality of the test anxiety, other that distinguishes the cognitive and affective components, and one that comprising four dimensions, worry, interference, lack of confidence and emotionality like primary factors and total test anxiety like secondary factor. Fit indices for the last model were all adequate. Are discussed the results, the use of items parcels and the importance of multidimensional instruments of test anxiety in Spanish language
Estrategias de aprendizaje y ansiedad ante los exámenes en estudiantes universitarios
Luis Alberto Furlan,Javier Sánchez Rosas,Daniel Heredia,Sebastián Piemontesi
Pensamiento Psicológico , 2009,
Abstract: Diversas investigaciones coinciden en se alar que la elevada ansiedad frente a los exámenes está asociada a la baja habilidad para el estudio y al uso de estrategias superficiales de procesamiento de la información, existendo influencias recíprocas entre dichas variables. De acuerdo a esta perspectiva, se evaluó el uso de estrategias de aprendizaje en 816 estudiantes universitarios con elevada, media o baja ansiedad frente a los exámenes. Adicionalmente, se analizaron las relaciones entre las cuatro dimensiones de la ansiedad y las estrategias de aprendizaje. Los estudiantes con elevada ansiedad utilizaron más frecuentemente estrategias de repetición y búqueda de ayuda académica y los de baja ansiedad, estrategias de estudio reflexivo. La falta de confianza correlacionó negativamente con estrategias de estudio reflexivo, repetición, búsqueda de ayuda académica y regulación del tiempo y esfuerzo. En sentido opuesto, la preocupación se asoció positivamente con tres de estas estrategias.
El abordaje comparativo de 'La conquista' en dos autores mestizos: Garcilaso de la Vega y Ruiz Díaz Guzmán
Pardo,Sebastián Eduardo;
Memoria americana , 2011,
Abstract: this paper analyses the representation of colonial domination, process commonly known as "the conquest", in the work of two writers belonging to the first half-breed generations of the early 17th century: garcilaso de la vega and ruy díaz de guzmán. the selection is based on two fundamental criteria: on the one hand both declare themselves as "naturales" and reveal a strong sense of belonging regarding the cultural areas they describe; on the other hand, both attach themselves to opposite ethnic identities, thus maintaining a different relationship with the complex problems of mestizaje and miscegenation -while garcilaso claims to be an inca, ruy díaz de guzmán introduces himself as a spaniard. therefore, the biographies of both authors are discussed in order to understand their life trajectories, ideologies and work from a comparative point of view.

Abstract: El artículo propone analizar la representación del proceso de dominación colonial, coloquialmente conocido como "La Conquista", en los trabajos de dos autores pertenecientes a las primeras generaciones de mestizos de principios del siglo XVII: Garcilaso de la Vega y Ruy Díaz de Guzmán. La elección responde a dos cuestiones fundamentales; por un lado, ambos expresan un fuerte sentido de pertenencia regional al autodenominarse "naturales" de las áreas culturales sobre las cuales escriben; por la otra, ambos mantienen una relación compleja pero bien diferenciada con respecto a la problemática del mestizaje adscribiendo a identidades étnicas opuestas: mientras Garcilaso se presenta como inca, Ruy Díaz de Guzmán lo hace como espa ol. En este sentido se discutirán las trayectorias de los mencionados autores para llevar a cabo el análisis comparado de sus vidas, sus ideologías y sus obras.

Intersecciones en antropolog?-a , 2007,
Abstract: this paper presents archaeological and historical data obtained from valleys and foot-hills around the central sierras de córdoba, argentina, known as the sierras grandes. a preliminary analysis of late pre-hispanic social processes (ca 900-1573 ad) and continuities in native organization during the early spanish colonial period (1573-1620) is offered on the basis of these data. the late pre-hispanic period is defined by the development of processes of agricultural expansion in the region. the mountain societies integrated this agriculture into their traditional hunter-gatherer practices. in relation to this economic transformation, the evolution of the way of life (modo de vida) articulated several innovations and continuities. a small productive system, defined by little use of technology and high levels of loss, was configured. the reproduction of this system permitted population dispersal and the continuity of a period characterized by political fragmentation. at the same time, a significant intensification of extractive practices has been recorded, implying a continuity of mechanisms such as seasonal dispersion and the rise of group contexts for the appropriation and consumption of wild resources. the complexity of these processes is a warning about the limitations of some categories and concepts used to describe the population in the case study area: small agriculturalist societies, formative adaptation, tribal organization, neolithization, etc.

Abstract: Se efectúa un breve repaso de la información arqueológica e histórica disponible para los diferentes valles y piedemontes que rodean al cordón central de las Sierras de Córdoba (Argentina), también conocido como Sierras Grandes. A partir de la misma se plantean consideraciones generales sobre los procesos sociales del período prehispánico tardío (ca. 900-1573 DC), así como en relación a algunas persistencias de la organización nativa durante los inicios del régimen colonial espa ol (1573-1620 DC). El período tardío es definido por el advenimiento de la producción agrícola que las sociedades serranas integraron a sus tradicionales prácticas de caza y recolección. La evolución del modo de vida articuló, a partir de esta transformación económica, una serie de innovaciones y permanencias. Se configuró un peque o sistema productivo, caracterizado por la escasa tecnificación y los elevados niveles de pérdida, cuya reproducción favoreció la dispersión poblacional y el sostenimiento de un escenario de alta fragmentación política. En forma paralela, se registra una marcada intensificación de las prácticas extractivas, a través de la continuidad de mecanismos como la dispersión estacional y el surgimiento de contextos grupales de apropiación y consumo de recursos silvestres. La complejidad de estos procesos advierten sobre las dificultades de algunas categorías y conceptos utilizados para describir y especificar el caso de estudio: sociedades agrícolas de peque a escala, adaptación formativa, organización tribal, neolitización, etc. This paper presents archaeological and historical data obtained from valleys and foot-hills around the central Sierras de Córdoba, Argentina, known as the Sierras Grandes. A preliminary analysis of late pre-Hispanic social processes (ca 900-1573 AD) and continuities in native organization during the early Spanish colonial period (1573-1620) is offered on the basis of these data. The late pre-Hispanic period is defined by the development of processes of agricultural expansion in the region. The mountain societies integrated this agriculture into their traditional hunter-gatherer practices. In relation to this economic transformation, the evolution of the way of life (modo de vida) articulated several innovations and continuities. A small productive system, defined by little use of technology and high levels of loss, was configured. The reproduction of this system permitted population dispersal and the continuity of a period characterized by political fragmentation. At the same time, a significant intensification of extractive practices
Fluoride retardation from quartz sand-packed column tests
Usunoff,Eduardo; Weinzettel,Pablo; Dietrich,Sebastián;
Geoacta , 2009,
Abstract: inasmuch as both low and high concentrations of f- in groundwater have different detrimental effects on human health (increased dental caries, and mottled enamel or even severe structural bone deformations, respectively), many efforts have focused on the movement of such anion in aqueous systems. it is so because water drinking is the main intake of f- by humans. this paper presents the results of seven dynamic experiments in which solutions of varying [f-], ph, and flow velocities circulated through columns packed with clean quartz sand. the breakthrough data were analyzed by means of a computer code adapted to the estimation of equilibrium and non-equilibrium solute transport parameters from miscible displacement experiments in a steady-state, uniform flow field using a pulse-type or continuous source. it was found that larger retardation factors (r) are associated with low ph, low [f-] in the feed solutions, and larger flow velocities. such results appear to be related to the form of the f species, the rather weak bond between the adsorbate and the quartz sand, and stronger anion repulsion at low pore velocities. the estimated values for r vary between 1,22 and 1,50, whereas the distribution coefficients were in the range of 0,1 to 0,05 l kg-1. it should be said that the breakthrough curves display hysteresis, leading to a desorption behavior that proceeds faster than the adsorption process.
