Elements traça en esfalerites i galenes del dipòsit de Cierco (Pb-Zn), Alta Ribagorça, Pirineu Central

El diposit consisteix en dos filons E-W, tallats per un altre N-S. El rebliment filonia és zonat amb esfalerita- galena-calcita als nivells profunds i galena-baritina als superiors. Els elements traca en esfalerites i galenes, plenament separades, han estat analitzats mitjancant fluoresckncia de raigs X. Els resultats mostren que l'esfalerita concentra la majoria d'elements traca, preferentment Fe, Co, Cd, Sn, Sb, Ga, Cu, Ge i Ag, amb una bona correlació entre els sis primers. La galena concentra únicament Sb, Ag i As, amb bona correlació entre els dos primers. Els continguts en elements traca estan homogkniament distribuits en tot el diposit

Contextualizing gender issues and inclusive education: an analysis of the perceptions of primary education teachers

This study explores the experiences and perceptions of primary education teachers regarding the struggle for gender equality in schools located in an area in northern Spain. In addition, it analyses the measures carried out in classrooms and schools to achieve this objective that are influenced by social and cultural factors, and does so within a scenario consisting of an inclusive school that advocates equality as one of its fundamental ethical principles. The study is included in the paradigm of qualitative research, and eight teachers from three public schools were interviewed. The teachers expressed their broad dissatisfaction with the generally limited involvement of the schools and the educational community in promoting gender equality, which is influenced by different social and cultural dynamics. Lines of action are proposed that motivate teachers to take responsibility for their teaching practice in order to guarantee gender equality in a context of cultural diversity

Links between ease of use, perceived usefulness and attitudes towards technology in older people in university: A structural equation modelling approach

Technological resources have the potential to improve the quality of life in a context in which social pressure for the use of these tools is increasing. In this sense, the adoption of technological resources by the elderly is a highly complex issue because numerous and varied factors are involved. Precisely for this reason, this study aims to analyze the effects that exist between a series of dimensions related to the perception of older people regarding the ease of use, the perceived usefulness of technological tools, attitudes towards technology and their intention to use them in everyday life. To do this, 415 adults (M = 66.27 years) enrolled in a program at the University of Experience in the Spanish context completed an online questionnaire. The application of a Structural Equations Model for data analysis highlights that the perceived ease of use of the technology has a positive effect on the perceived usefulness of these resources. Similarly, an indirect effect of the perceived usefulness of technology on the intention to use these resources is observed through the manifestation of positive attitudes towards the use of digital tools
