El reto del conocimiento en la practica del Trabajo Social

2005

En el presente artículo se pretende subrayar la importancia de que desde el Trabajo Social y la Educación Social se profundice en el conocimiento y la utilización de las Tecnologías de la Información y la Comunicación (TIC) como recurso y requisito para la intervención socioeducativa. Unas tecnologías que cada vez ostentan un mayor protagonismo en nuestra sociedad y ante las que, además, es preciso constituir una adecuada respuesta desde las entidades que habrán de asumir, tarde o temprano, la responsabilidad de atender las nuevas situaciones de exclusión a las que se podrán ver sometidos aquellos que no tengan posibilidad de acceder a ellas. En este sentido, se destaca la necesidad de que …

Cross-lagged associations between problem behaviors and teacher-student relationships in early adolescence

2017

This study investigated the cross-lagged associations between teacher-student relationships and problem behaviors in a sample of 440 Finnish students (half of them identified as being at risk of reading difficulties). The degree to which these associations were moderated by a child’s gender, academic performance, risk for reading difficulties, parental education, and having the same teacher over 2 years was examined. The teachers evaluated the students’ problem behaviors and reported closeness and conflict with a particular student. The results showed that the higher the students scored on externalizing problems in Grade 4, the more conflict teachers reported 2 years later. Moderator analy…

Environmental journalism as area of specialization in university classrooms

2014

Este número lleva por título "La comunicación en la profesión en la universidad de hoy". Informar sobre los asuntos relacionados con el medio ambiente se ha convertido en los últimos años en un área de especialización periodística consolidada al mismo tiempo que la actualidad demuestra que los asuntos ambientales son asuntos políticos, económicos y sociales. La enseñanza universitaria del Periodismo no puede ser ajena a la necesidad de conocer esta realidad transversal. Las exigencias de la implantación del Espacio Europeo de Educación Superior en nuestras universidades obliga a considerar nuevas fórmulas para la integración del medio ambiente en las aulas. Report environment issues has bec…

Note brevi a margine della proposta di riforma dei reati ambientali del gruppo di studio dell'associazione dei professori di diritto penale

2022

A partire dall’analisi della proposta di riforma dei reati contro l’ambiente elaborata dal Gruppo di studio dell’Associazione italiana dei Professori di Diritto Penale, il contributo riflette sui principali problemi teorici del diritto penale ambientale (tipizzazione dell’evento lesivo nelle fattispecie di inquinamento e di disastro ambientale, imputazione soggettiva dei delitti aggravati dall’evento, contrasto penale alle c.d. “ecomafie” nel settore dei rifiuti ecc.), mettendo a confronto le soluzioni suggerite nel testo con le prospettive di riforma contenute nella recente Proposta di Direttiva del Parlamento europeo e del Consiglio sulla Protezione dell’ambiente at- traverso il diritto p…

Starting from the analysis of the proposal for the reform of crimes against the environment drawn up by the Study Group of the Italian Association of Professors of Criminal Law the paper reflects on the main theoretical problems of environmental criminal law (typification of the event in pollution crime and environmental disaster crime mental element of crimes aggravated by the event fight to the so-called “ecomafie” in the waste sector etc.) comparing the solutions suggested in the text with the recent Proposal for a Directive of the European Parliament and of the Council on the Protection of the Environment through Criminal Law that replaces Directive 2008/99.Settore IUS/17 - Diritto Penale

Actuaciones de alumnos instruidos en la resolución algebraica de problemas en la hoja de cálculo y su relación con la competencia en el método cartes…

2013

Presentamos resultados de una investigación en la que, entre otros objetivos, se pretendía determinar cómo influía la enseñanza de la resolución algebraica de problemas en la hoja de cálculo en la competencia en el método cartesiano. La comparación de los cuestionarios administrados antes y después de la enseñanza puso de manifiesto un aumento del uso polisémico de la equis cuando se resolvía con lápiz y papel, y una disminución del uso del lenguaje del álgebra en los problemas de edades. Mostramos que estos resultados pueden atribuirse a la aparición de estrategias de resolución en la hoja de cálculo en las que las situaciones descritas en el enunciado se modelizaban mediante relaciones fu…

Some extensions of multivariate sliced inverse regression

2007

Multivariate sliced inverse regression (SIR) is a method for achieving dimension reduction in regression problems when the outcome variable y and the regressor x are both assumed to be multidimensional. In this paper, we extend the existing approaches, based on the usual SIR I which only uses the inverse regression curve, to methods using properties of the inverse conditional variance. Contrary to the existing ones, these new methods are not blind for symmetric dependencies and rely on the SIR II or SIRα. We also propose their corresponding pooled slicing versions. We illustrate the usefulness of these approaches on simulation studies.

Analysis of Word Problems in Primary Education Mathematics Textbooks in Spain

2021

A textbook constitutes the hegemonic material of the educational institution. It acts as a mediator between the official curriculum and the educational practice. Given its potential influence in the classroom, this study analyzes the treatment of word problems included in the mathematics textbooks published by the publishing houses with the greatest diffusion in Spain at every primary education grade. Three variables were analyzed: their semantic structure, their degree of challenge, and their situational context. The results indicate that most of the problems included in textbooks are characterized by low complexity and variability regarding their semantic structure. They are also characte…

Dificultades para Codificar, Relacionar y Categorizar Problemas Verbales Algebraicos: dos estudios con estudiantes de secundaria y profesores en form…

2014

En resolución de problemas verbales por transferencia, la activación de problemas ya conocidos que sirvan de guía, depende de las analogías percibidas entre éstos y el problema a resolver. Se desarrollan dos estudios relacionados para analizar en qué características se basan los estudiantes para codificar problemas y detectar sus analogías, en tareas de categorización (sorting). Se utilizaron técnicas cuantitativas y cualitativas combinadas. Primero se analizó cómo los estudiantes de secundaria son influidos por diferentes variables características de problemas de ciencias. Una gran proporción de sujetos no fue capaz de percibir las analogías y diferencias adecuadas entre problemas. El segu…

Symmetry of minimizers with a level surface parallel to the boundary

2015

We consider the functional $$I_\Omega(v) = \int_\Omega [f(|Dv|) - v] dx,$$ where $\Omega$ is a bounded domain and $f$ is a convex function. Under general assumptions on $f$, G. Crasta [Cr1] has shown that if $I_\Omega$ admits a minimizer in $W_0^{1,1}(\Omega)$ depending only on the distance from the boundary of $\Omega$, then $\Omega$ must be a ball. With some restrictions on $f$, we prove that spherical symmetry can be obtained only by assuming that the minimizer has one level surface parallel to the boundary (i.e. it has only a level surface in common with the distance). We then discuss how these results extend to more general settings, in particular to functionals that are not differenti…

Enhancing Collaborative Governance to Build Active Citizenship through Social Inclusion in Historical Neighborhood Regeneration: A Dynamic Performanc…

2021

Active citizenship and collaborative governance can be supported to enhance urban regeneration and social inclusion through Dynamic Performance Governance (DPG). The problem of urban decay and urban decline is identified as the main problem that continues to affect cities and urban areas. The study focuses on the urban regeneration experience of the historic urban neighborhood of Ballaro which is located in the historic city of Palermo. Urban regeneration is essential for transforming urban neighborhoods which are at risk of decline and blight. However, the lack of a social aspect such as social inclusion through active citizenship was identified to affect the sustainability of urban regene…
