The Dialogic Turn in Educational Psychology

The increasing presence of and claim for dialogue in today"s society has already had an impact on the theory and practice of learning. Whereas in the past individual and cognitive elements were seen as crucial to learning, since about two decades ago, scientific literature indicates that culture, interaction and dialogue are the key factors. In addition, the research project of highest scientific rank and with most resources dedicated to the study of school education in the Framework Program of the European Union: INCLUD-ED shows that the practices of successful schools around Europe are in line with the dialogic approach to learning. This article presents the dialogic turn in educational psychology, consisting of moving from symbolic conceptions of mind and internalist perspectives that focus on mental schemata of previous knowledge, to theories that see intersubjectivity and communication as the primary factors in learning. The paper deepens on the second approach.

Lésions induites par les pistolets à impulsion électrique de type Taser [Health Risks Concerning Electronic Control Devices]

Les pistolets à impulsion électrique (PIE) sont de plus en plus fréquemment utilisés en Europe ces dernières années, le modèle le plus connu étant le Taser®. Les connaissances scientifiques concernant les PIE et leurs effets potentiels restent toutefois limitées. Nous avons conduit une revue de littérature afin d'évaluer les implications potentielles de leur utilisation en termes de sécurité, de morbidité et de mortalité. Une exposition unique chez un individu sain peut généralement être considérée comme peu dangereuse. Les sujets à risque de complications sont les individus exposés à de multiples décharges, les personnes sous l'influence de substances psychoactives, ceux qui montrent des signes d'agitation extrême, ou encore les individus présentant des comorbidités médicales. L'éventail des complications pouvant survenir lors de leur exposition est large et inclut les lésions provoquées par les impacts des électrodes, les traumatismes liés à la chute induite par la paralysie transitoire ou des complications cardiovasculaires. Dans ce contexte, les personnes exposées doivent être examinées attentivement, et les éventuelles lésions traumatiques doivent être exclues. The use of electronic control devices (ECD), such as the Taser®, has increased in Europe over the past decade. However, scientific data concerning the potential health impact of ECD usage remains limited. We reviewed the scientific literature in order to evaluate the safety, mortality, and morbidity associated with ECD use. Exposure of a healthy individual to a single ECD electroshock can be considered generally safe. Complications can, however, occur if the patient is subject to multiple electroshocks, if the patient has significant medical comorbidities, or when exposure is associated with drug abuse or agitated delirium. The broad spectrum of potential complications associated with ECD exposure includes direct trauma caused by the ECD electrodes, injuries caused by the transient paralysis-induced fall, and cardiovascular events. An ECD-exposed patient requires careful examination during which traumatic injuries are actively sought out.

Autoarchivo de artículos biomédicos en repositorios de acceso abierto

Introducción y desarrollo. El acceso abierto es el acceso digital, en línea y libre de barreras económicas, o al menos de algunos derechos de explotación (copyright), a la producción científica o académica de nuestros profesores e investigadores. El autoarchivo o depósito de estos trabajos en repositorios institucionales (vía verde) está cada vez más presente entre las actividades de la comunidad científica. Además de beneficiarse de sus ventajas, los autores son, cada vez con más frecuencia, requeridos por las instituciones financiadoras de la investigación y por las suyas propias para que depositen sus trabajos en repositorios. En el entorno biomédico esto es más necesario, por la repercusión que puede tener en la salud de las personas que los profesionales dispongan o no de la mejor evidencia científica. Para que esto sea posible, los autores deben conocer qué es y cómo funciona un repositorio y deben saber manejar herramientas fáciles como Sherpa/RoMEO o DULCINEA para averiguar qué derechos retienen como autores y si éstos les permiten llevar a la práctica el autoarchivo. PubMed Central y sus homólogos británico y canadiense son los principales repositorios temáticos del ámbito biomédico. En nuestro país no existe ninguno de naturaleza similar; sin embargo, la mayoría de las universidades y el Consejo Superior de Investigaciones Científicas disponen de un repositorio institucional en funcionamiento. Conclusión. La mayor visibilidad de los resultados de investigación y su repercusión en una mayor y más temprana citación es uno de los beneficios más esgrimidos del acceso abierto, así como la eliminación de las barreras económicas en el acceso a la información contrastada para colectivos habitualmente excluidos

La percepció social entorn al delicte i els condicionants que operen en aquesta percepció al municipi de Sant Joan de Vilatorrada

L'objectiu general d'aquesta investigació social és aprofundir en el coneixement de la percepció social entorn al delicte, així com en els condicionants que operen en aquesta percepció al municipi de Sant Joan de Vilatorrada. S'incidirà en el coneixement d'aquesta percepció a partir de la por al delicte i la inseguretat ciutadana, dos fenòmens similars, però no exactament iguals. I els condicionants responen als factors que tenen una influència sobre la por al delicte i la inseguretat ciutadana. D'aquests factors se n'han detectat 34, i només s'estudiaran els nou més rellevants amb la finalitat de saber quin d'ells és el més influent. Tal com s'ha comentat, l'àmbit d'estudi és la població de Sant Joan de Vilatorrada, tot justificant-se pel fet de permetre incorporar el factor de tenir un centre penitenciari al mateix municipi en el qual es resideix. La metodologia escollida és la quantitativa, tot utilitzant la tècnica de l'enquesta. Per altra banda, la mostra és de 2.030 subjectes, tenint present que s'ha obtingut a partir d'una fórmula destinada a calcular les poblacions finites. Finalment, s'han presentat quatre limitacions de l'estudi, tot optant per aportar diverses solucions.

Le sentiment de gratitude en soins palliatifs : un facteur contribuant au bien-être et à la qualité de vie ? [Gratitude in palliative care: is it a psychological factor contributing to well-being and quality of life?]

En s'appuyant sur la littérature scientifique et l'état de la recherche, cet article a pour objectif de montrer pourquoi la prise en compte du sentiment de gratitude peut s'avérer utile dans le contexte palliatif en mettant en évidence dans quelle mesure cette émotion ou disposition individuelle: 1) entre en résonance avec le concept de croissance posttraumatique et certains enjeux relationnels chez les patients en fin de vie; 2) représente un facteur favorisant le bien-être et la qualité de vie; 3) peut être considérée comme un facteur protecteur contre les troubles psychopathologiques. Based on the scientific literature and the state of research, this article aims to show why the feeling of gratitude may represent a point of interest for palliative care. We will highlight the following in this article: 1) why this feeling of gratitude resonates with the concept of post-traumatic growth and relational challenges in end-of-life patients; 2) in which measure this feeling represents a factor contributing to well-being and quality of life; 3) in which measure this feeling may be considered as a protective factor against psychopathological troubles.

An analysis of the determinants in economics and business publications by spanish universities between 1994 and 2004

The objective of this study consists, firstly, of quantifying differences between Spanish universities’ output (in terms of publications and citations), and secondly, analysing its determinants. The results obtained show that there are factors which have a positive influence on these indicators, such as having a third-cycle programme, with public financing obtained in competitive selection procedures, having a large number of full-time researchers or involvement in collaborations with international institutions. However, other factors which appear to have the opposite effect were also noted. These include a higher number of students per lecturer or a lower proportion of lecturers with recognised six-year periods.

Patrones de publicación internacional, (ssci) de los autores afiliados a universidades españolas, en el ámbito económico-empresarial (1994-2004)

In this paper we analyse the status of scientific publications in Economics and Business in Spain (1994-2004). We focus our research in showing the preferred journals of the authors affiliated to Spanish universities, the quality of these journals and also the evolution along the decade. Throughout the paper we study deeply the areas of knowledge: which are more productive and also how the articles are distributed among Universities considering the areas of knowledge. The results show an important stability concerning the growth of published articles considering different levels of quality of journals. A second result is the important concentration in a few areas of knowledge: Fundamentals of Economic Analysis and Applied Economics. We observe a degree of specialization of several universities. Last, we display the relationship between journal publication and university’s publication pattern.

Entrenamiento de la fuerza orientado a la mejora de la velocidad de golpeo en tenis

El golpeo de la bola a velocidades elevadas, es un factor determinante para el rendimiento en el tenis moderno. Durante los últimos 20 años se ha producido una gran evolución del juego y los cambios en el juego moderno se han traducido en el uso de poderosos servicios y golpes de fondo. Aunque la fuerza es una capacidad determinante desde la perspectiva de la condición física, ha habido poca investigación para fundamentar la eficacia de los programas de entrenamiento de fuerza para los jugadores de tenis. El objetivo de este estudio es realizar una revisión sobre los criterios básicos para dirigir correctamente el entrenamiento de la fuerza orientado a la mejora de la de la velocidad de golpeo de la pelota. Aunque las necesidades de fuerza dinámica máxima (FDM) en los golpeos son bajas, la literatura científica parece apuntar que unos adecuados niveles de FDM ejercen efectos positivos sobre el aumento de velocidad de golpeo en el tenis. La mejora y mantenimiento de esta manifestación de fuerza se busca a expensas de factores neurales. Los entrenamientos de fuerza útil deben utilizar medios que permitan ejecutar el gesto técnico, implicar las mismas cadenas musculares, rango de movimiento o velocidades de ejecución. En este sentido, se han propuesto la utilización de pelotas medicinales, mancuernas de peso ligero, gomas elásticas, máquinas multifuncionales de resistencia neumática o poleas.

Nomenclatura na língua portuguesa em cromatografia multidimensional abrangente

Comprehensive Multidimensional Chromatography is a relatively new analytic technique, which is receiving growing attention in many parts of the world, including recently in Brazil. This work presents terms in Portuguese which are commonly used in Comprehensive Multidimensional Chromatography in order to help standardize the vocabulary employed in this area in the scientific literature. It also includes some symbols, their nominations, and explanation of some terms, whenever necessary. This proposal does not intend to be comprehensive or definitive; on the contrary, it intends to be a first step in the process of establishing a standardized nomenclature, serving as a base for a further sound discussion in the scientific community realm.

Natural Science in the Bothnian Sea During 1975-2008: A Review

The Baltic Sea is one of the most studied areas in the world. However, parts of its northernmost reach, the Bothnian Sea, seem to be under represented in the natural scientific literature compared to other parts of the Baltic. The Bothnian Sea represents a unique inland sea environment for the scientific community to study due to its shallowness and low salinity. The natural sciences research carried out on the Bothnian Sea has been reviewed between 1975 and 2008. This time period was chosen to continue on from an earlier review paper ending in 1974. Along with the number of papers published the goal was also to review the content of the papers, indentifying dominating themes to evaluate gaps in the current knowledge on the Bothnian Sea and provide recommendations for topics of future research focus. In a classification into specific research topics biodiversity was the leading research focus followed by chemical and physical oceanography, pollution and toxins, and fish biology and fisheries. The current good condition of the Bothnian Sea is highly valued with its historically less eutrophic and clearer waters when compared to the Baltic. However, today the Bothnian Sea is facing eutrophication resulting from nutrient-rich water transported by the many rivers draining into it from Sweden and Finland making it an area in need of protection and preservation. More human activity will also concentrate on the Bothnian Sea in the future. Therefore the use of the sea and its coastal areas must be planned carefully to minimize the harmful effects of this increasing human activity. To achieve this more information is needed for the basis of Integrated Coastal Zone Management (ICZM) and maritime spatial planning (MSP). For example, for the Bothnian Sea the information on the underwater nature which is essential for ICZM is so far missing to a large extent. Specific biological, chemical and physical oceanographic information is needed to combine with economic analyses and environmental policies regarding this region. More research of a multidisciplinary nature is required on the unique Bothnian Sea environment and this we feel is best achieved through a joint Finnish-Swedish research strategy.

La promoción del pensamiento crítico en el Aprendizaje Basado en Problemas (ABP). Un análisis a partir de los instrumentos de medición

[spa] La literatura científica sobre el Aprendizaje Basado en Problemas (ABP) ha dedicado una atención creciente a la cuestión del pensamiento crítico a lo largo de las dos últimas décadas. Los trabajos de investigación que se han llevado a cabo en los distintos contextos disciplinares de la educación superior presentan definiciones e instrumentos de medición del pensamiento crítico dispares. El presente artículo parte de dicha apreciación y trata de revisar sistemáticamente los mencionados trabajos con un doble objetivo: por un lado, esbozar una clasificación de los instrumentos de medición del pensamiento crítico de estudiantes de ABP y, por el otro, mostrar una panorámica de las evidencias hasta ahora obtenidas; todo ello con la finalidad de animar a profesores, estudiosos y autoridades académicas a seguir avanzando en esta línea de investigación. [eng] Critical thinking has received growing attention from scientific literature on Problem-Based Learning (PBL)during the last two decades. The research carried out in different disciplinary contexts of higher education presents disparate definitions and measuring instruments of critical thinking. This article aims to review systematically the mentioned literature with a dual purpose: on the one hand, to outline a classification of instruments measuring PBL students' critical thinking, on the other, to show an overview of the evidence so far obtained; all of this with the ultimate purpose of encouraging teachers, scholars and academical authorities to proceed further in this line of research.
