Búsqueda colaborativa para el apoyo a la recomendación de Objetos de Aprendizaje

Este trabajo propone un marco para la búsqueda, selección, valoración y recomendación tanto individual como en grupo de objetos de aprendizaje implementado dentro del sistema de recomendación hibrido DELPHOS. Para facilitar la búsqueda colaborativa se utilizan varias aproximaciones de creación de grupos. También se van a facilitar varias funciones colaborativas como la calificación, el etiquetado y la posibilidad de comentar los objetos. Finalmente se proporcionan varias actividades sociales para poder añadir o recomendar objetos a un grupo, visualizar y calificar objetos añadidos por otros usuarios del grupo, y comunicarse mediante chat o correo electrónico con otros miembros del mismo para llegar a tomar decisiones sobre los objetos más adecuados para los intereses del grupo.

¿Qué caracteriza el conocimiento del profesor de matemáticas en la planificación del concepto de límite al infinito de una función para su enseñanza?

Se reportan avances de una investigación que se interesa por determinar las características del conocimiento matemático para la enseñanza del concepto de límite al infinito de una función que pone en acción el profesor en la planificación del tópico. El estudio se fundamenta en el modelo Conocimiento Matemático para la Enseñanza (MKT). En el estudio participan dos profesores de matemáticas de España y uno de México. Los datos se obtienen mediante una entrevista semiestructurada que involucró aspectos sobre los datos personales, el aula de clases, la planificación del profesor y del investigador sobre el tópico. El análisis de los daros se realiza en tres fases: generación de las unidades de análisis, agrupamiento en categorías de dichas unidades y determinación de las características del conocimiento del profesor. Los resultados evidencian que el profesor pone en acción los subdominios del MKT cuando planifica la enseñanza del concepto de límite al infinito de una función.

Is the cinematic newsreel the strongest weapon? The "Luce" newsreel reception during fascism

The Luce newsreel was a fascist-pivotal propaganda instrument. Mussolini thought movies were the strongestweapon; however, the efficiency of cinematographic propaganda on people did not work as well as expected,especially nonfiction. This article intends to value, through oral testimonies, the influence of Lucenewsreel on the Italian population during fascism, the degree of truth of film news, and which of those piecesof news were more repeated, as well as the influence of the Italian and its leader image on the collective mind.

Gender stereotypes: sexuality and contraception in Mexican university students of middle class

Since feminist studies and gender perspective, sexuality and reproduction continue to be a topic of interest in Mexico. The objective of this study was to identify gender stereotypes in sexuality and contraception practices in Mexican university students of middle class. We used a qualitative methodology with in-depth interviews, using as analysis axes the sexual and contraception practices. The results showed gender stereotypes in university students as active, seductive and conquerors, characterized by a double standard of morality in the type of relationship: Formal where love, affection, trust and commitment are present, and Informal, where a love relationship or sexual exclusivity is not incorporated.

Return Migration in the Ecuadorian and Bolivian population: motivations, strategies and discourses

This article analyses the motivations for return migration among the Ecuadorians and Bolivians who, after living in Spain, returned to their countries of origin during the economic crisis that started in 2008. From the analysis of 22 interviews in-depth which took place in Ecuador and 38 in Bolivia to women, men and young people from migrant families, this decision-making process is shown to be embedded into a gendered dynamics of relationships. Particular detail is given to affective and economic elements that had an influence on the decision to return, as well as to the strategies deployed to project their readjustment back in origin. Males and females occupy differential positions within the family, work and social circle, their expectations being built in a gendered manner. Despite the fact migration has brought women greater economic power within the family group, their reintegration upon return redefines their role as main managers in the household and the dynamics that allow their social reproduction. Men, for their part, aspire to refresh their role as providers in spite of their frail labour position upon return. Social mobility for females is passed on through generations by a strong investment on education for their daughters and sons, while for males this mobility revolves around setting up family businesses and around their demonstrative abilities.

Ecuadorian migration and family strategies of social mobility: dialectic relation between emotional and financial capital

This text deals with transnational strategies of social mobility in Ecuadorian migrant households in Spain. We apply the capital accumulation model (Moser, 2009) for this purpose. The main target of this article is, beyond thinking in terms of capital stock and accumulation, the analysis in depth of the dynamics of the different types of capital, that is to say, how they interact with each other in the framework of the social mobility strategies of the migrants and their families. We are bringing into light the way some households adopt investing decisions in capitals that don't translate into any addition or earnings in all cases, on the contrary, concentrating all their efforts on the accumulation of a certain asset they may, in some cases, lead to a loss of another. We will concentrate our analysis primarily on the dynamics between the physical and financial capital and the social and emotional capital, showing the tensions produced between these two types of assets. At the same time, we will highlight how migrants negotiate their family strategies of social mobility in the transnational area. Our study is based in empirical material obtained from qualitative fieldwork (in-depth interviews) with families of migrants in the urban district of Turubamba Bajo -(south of Quito) and in Madrid. A series of households were selected where interviews were carried out in the country of origin as well as in the context of immigration, with different family members, analysing the transnational social and economic strategies of families of migrant members. Family members of migrants established in Spain were interviewed in Quito, as well as key informants in the district (school teachers, nursery members of the staff, etc.). The research was framed within the projects "Impact of migration on the development: gender and transnationalism", Ministry of Science and Innovation (SEJ2007/63179) (Laura Oso, dir. 2007-2010),"Gender, transnationalism and intergenerational strategies of social mobility", Ministry of Economy and Competitiveness (FEM2011/26210) (Laura Oso, dir. 201-1-2015) and “Gender, Crossed Mobilities and Transnational Dynamics”, Ministry of Economy and Competitiveness (FEM2015-67164).
