Abstract Background Alcohol consumption is popular among adolescents and young people and adolescent non-drinkers may be socially excluded and/or stigmatized. The aim of this qualitative study was to explore the social life of young non-drinkers (14–20 years old), to understand how they live their non-drinking and how they are perceived by their drinking peers. Methods We conducted a qualitative research on non-consumption of alcohol in the French-speaking region of Switzerland. Our study included 63 young people divided into 12 focus groups aged 14 to 20 years. Results Overall, young non-drinkers would be a minority in their peer groups, leading some of them to feel out of the norm. Participants reported that not drinking alcohol is generally questioned and non-drinkers are almost always asked to justify their non-consumption. Finally, non-drinkers are sometimes automatically designated as resources who have to control the drinking of others and/or are the ones who help their drinking-peers if they are drunk and need help, a status that can put them under pressure. Conclusions It is important to normalize the non-consumption of alcohol and make non-drinkers visible by including them in school-based prevention interventions.

El objetivo principal de esta investigación es analizar las propiedades psicométricas de la Escala Gencat de Calidad de Vida en una muestra de 72 personas usuarias de la Oficina Municipal de Atención para Personas en Situación de sin Hogar de la ciudad de Lleida. El análisis de los 69 ítems se ha basado en la Teoría Clásica de los Test y en la Teoría de Respuesta al Ítem. Los resultados del alfa de Cronbach muestran valores adecuados, situándose entre .749 y .853. Según el modelo de Escalas de Clasificación la confiabilidad es alta con valores superiores a .95 en todas las dimensiones. La mayoría de ítems se ajusta al modelo. La limitación más importante del estudio es el tamaño de la muestra, que disminuye su confiabilidad. A pesar de ello se puede concluir que la escala posee evidencias suficientes de fiabilidad para poder evaluar la calidad de vida de las personas sin hogar.

La Convención de los Derechos del Niño (CDN, 1989) es actualmente el tratado internacional más ratificado. Distintos autores han puesto de relieve su potencialidad para una educación moral y en la ciudadanía. Aun así, paradójicamente, distintas investigaciones informan de su incorporación escasa u ocasional en las prácticas escolares. En este artículo se realiza una aproximación a las experiencias escolares sobre participación, la tercera P de la CDN, desde la pluralidad de voces y actores de la comunidad educativa, mediante 14 grupos de discusión en 11 comunidades autónomas del estado español. El análisis de los discursos evidencia bajos niveles de participación del alumnado en la vida escolar. Pero, a la vez, se constata un escenario educativo propicio para el desarrollo de proyectos que contribuyan a la participación infantil, así como a la incorporación de la CDN como elemento motor de la vida del centro y referente integrador de los distintos proyectos de centro.

Fundamentos: El sobrepeso y la obesidad infantil han aumentado progresivamente en las últimas décadas, especialmente en países del sur de Europa. El objetivo del estudio fue identificar la prevalencia de sobrepeso, obesidad y sus determinantes en escolares de 8-9 años de Barcelona. Métodos: Estudio transversal descriptivo de una muestra representativa de 3.262 escolares en 2011. Se calculó el Índice de Masa Corporal (IMC) siguiendo los criterios establecidos por la Organización Mundial de la Salud (z-scores). Se estudiaron variables sobre conducta alimentaria, actividad física y uso de nuevas tecnologías mediante 2 cuestionarios. Se ajustaron modelos de regresión logística, obteniendo odds ratio ajustadas e intervalos de confianza (95%). Resultados: La prevalencia de sobrepeso fue del 24,0% y de obesidad del 12,7%. La obesidad fue significativamente mayor en niños que en niñas (14,8% vs. 10,8%). No se observaron diferencias estadísticamente significativas según IMC en el cumplimiento de las recomendaciones de práctica de actividad física ni uso de nuevas tecnologías. Los factores asociados a la obesidad en niños fueron asistir a escuela situada en barrios de nivel socioeconómico desfavorable [ORa=1,88 (1,35-2,63)], pertenecer a familia inmigrante [ORa=1,57 (1,12- 2,20)], no comer en el colegio [ORa=1,76 (1,20-2,59)] y hacer alguna comida solo [ORa=1,95 (1,27-3,00)]. En niñas fueron pertenecer a familia monoparental [ORa=1,58 (1,06-2,34)] y familia inmigrante [ORa=1,53 (1,07-2,18)]. Conclusiones: La prevalencia de obesidad infantil en Barcelona es alta. Es más frecuente en niños, siendo los determinantes sociales los factores asociados de mayor relevancia.

'Translanguaging' has become the most popular term in discussions about how to use learners' languages as resources for target language teaching/learning, but it has also become ambiguous because it is being developed in proposals adopting different perspectives on multilingualism. The first aim of this article is to offer an overview of the two main current proposals of translanguaging together: García and colleagues' 'spontaneous translanguaging' and Cenoz and Gorter's 'pedagogical translanguaging'. 'Spontaneous translanguaging' argues that languages in the mind are represented as one single system and that the notion of transfer, consequently, must be rejected. This article argues that this view may not be practical because it makes it difficult for teachers to conceptualise what they are doing when raising awareness of similarities between learners' languages. 'Pedagogical translanguaging', by contrast, centres around transfer. Whereas transfer is traditionally seen as unintentional 'interference', pedagogical translanguaging considers it a phenomenon that learners can use intentionally and creatively, and which teachers could promote by raising learners' awareness of similarities between their languages. However, very little is known about how learners use transfer unintentionally versus intentionally. This article discusses key findings and implications from Fuster's (2022) initial study on intentionality in lexical transfer within pedagogical translanguaging.

Even though malaria was eradicated from Europe after the mid-20th century, in 2017, more than 8000 imported cases were reported in the continent. Due to travel routes to endemic areas, climate change, and the presence of native vector mosquitoes (genus Anopheles), the re-establishment of autochthonous malaria transmission is a current concern. Anopheles atroparvus (Van Thiel, 1972) is one of the 11 sibling species within the Palearctic Anopheles maculipennis complex, which formerly were considered the main vectors of the disease in the European continent. The microbiota (bacteria and viruses) of vector species has been demonstrated to play a significant role in the biology of these organisms, including their infection susceptibility and their capacity to transmit disease-causing agents. Recently, with the improvement of metagenomics techniques, several viruses that naturally infect vector mosquitoes have been identified. The purpose of the present study was to characterize, for the first time, the virome present in An. atroparvus from the Ebro Delta and assess its evolution after ten generations in the laboratory. Small RNA sequencing was used to characterize the virome from wild-caught An. atroparvus females and from the tenth generation produced under controlled laboratory conditions. Through this approach, we were able to identify viral linages previously reported in other invertebrates, such as Chaq virus and several Partiti-like viruses. A reduction in the viral composition was observed during the colonization process. The present study contributes to the understanding of the viral diversity of a medically relevant vector species in its natural setting and under confinement, and sets a baseline for further studies to assess the potential implications of these viruses in the transmission of pathogens.

Worldwide, emerging and re-emerging infectious diseases (EIDs) are a major burden on public and animal health. Arthropod vectors, with mosquitoes being the main contributors of global disease, transmit more than 70% of the recognized EIDs. To assess new alternatives for arthropod-borne viral diseases surveillance, and for the detection of new viruses, honey-baited Flinders Technology Associates (FTA) cards were used as sugar bait in mosquito traps during entomological surveys at the Llobregat River Delta (Catalonia, Spain). Next generation sequencing (NGS) metagenomics analysis was applied on honey-baited FTA cards, which had been exposed to field-captured mosquitoes to characterize their associated virome. Arthropod- and plant-infecting viruses governed the virome profile on FTA cards. Twelve near-complete viral genomes were successfully obtained, suggesting good quality preservation of viral RNAs. Mosquito pools linked to the FTA cards were screened for the detection of mosquito-associated viruses by specific RT-PCRs to confirm the presence of these viruses. The circulation of viruses related to Alphamesonivirus, Quaranjavirus and unclassified Bunyavirales was detected in mosquitoes, and phylogenetic analyses revealed their similarities to viruses previously reported in other continents. To the best our knowledge, our findings constitute the first distribution record of these viruses in European mosquitoes and the first hint of insect-specific viruses in mosquitoes’ saliva in field conditions, demonstrating the feasibility of this approach to monitor the transmissible fraction of the mosquitoes’ virome. In conclusion, this pilot viromics study on honey-baited FTA cards was shown to be a valid approach for the detection of viruses circulating in mosquitoes, thereby setting up an alternative tool for arbovirus surveillance and control programs.

Dispersal is a critical determinant of animal distribution and population dynamics, and is essential information for management planning. We studied the movement patterns and the influence of habitat and biotic factors on Mediterranean brown trout (Salmo trutta) by mark-recapture methods in three headwater streams of the Ebro Basin (NE Iberian Peninsula). Fish were sampled by electrofishing on five occasions over 18–24 months and movements of over 3,000 individually tagged trout (age 1+ onwards) were recorded. Most of the tagged fish exhibited limited movement and were recaptured within 100 m from the initial capture section. Small seasonal differences in the movement pattern were observed, but in two of the streams, displacement distances increased prior the spawning period in autumn. The frequency distributions of dispersal distances were highly leptokurtic and skewed to the right and fitted well to a two-group exponential model, thus trout populations were composed of mobile and stationary individuals, the latter being the predominant component in the populations (71.1–87.5% of individuals). The mean dispersal distances, for fish captured at least in three sampling events, ranged 20.7–45.4 m for the stationary group and 229.4–540.5 m for the mobile group. Moving brown trout were larger than non-moving individuals and exhibited higher growth rates in two of the streams. Habitat features were not consistently linked to movement rates, but there were some interaction effects between stream and habitat characteristics such as depth, cover and water velocity.

La Convención de los Derechos del Niño (CDN) es una herramienta fundamental para la educación de niños, niñas y adolescentes. Ésta debe entenderse como el marco de referencia universal que contribuye a formar niños y niñas capacitados para ejercer sus derechos de ciudadanía. Sin embargo, conocemos muy poco sobre cómo los derechos de la infancia y la ciudadanía global se integran en el sistema educativo español. El objetivo de este trabajo es identificar las necesidades formativas que tiene la comunidad educativa en relación a la CDN desde las dimensiones cognitiva, metodológica y actitudinal. Se trata de una investigación cualitativa que ha contado con la participación de 124 personas representantes de la comunidad educativa (alumnado, docentes, padres y madres) distribuidas en 14 grupos de discusión desarrollados en 11 Comunidades Autónomas del territorio español. El análisis de contenido muestra la escasa incorporación en los centros escolares de la CDN, así como una la visión parcial de ésta por parte de los integrantes de la comunidad educativa. Se observan necesidades en la falta de estrategias de enseñanza-aprendizaje que fomenten la autonomía y la participación infantil en el aula y el centro. Finalmente, se observa la dificultad de posicionar a la infancia como sujeto de derechos con facultades para ejercer su ciudadanía.

Background: Childhood obesity preventive interventions should promote a healthy diet and physical activity at home and school. This study aims to describe a school-based childhood obesity preventive programme (POIBA Project) targeting 8-to-12- year-old. Design and methods: Evaluation study of a school-based intervention with a pre-post quasi-experimental design and a comparison group. Schools from disadvantaged neighbourhoods are oversampled. The intervention consists of 9 sessions, including 58 activities of a total duration between 9 and 13 hours, and the booster intervention of 2 sessions with 8 activities lasting 3 or 4 hours. They are multilevel (individual, family and school) and multicomponent (classroom, physical activity and family). Data are collected through anthropometric measurements, physical fitness tests and lifestyle surveys before and after the intervention and the booster intervention. In the intervention group, families complete two questionnaires about their children’s eating habits and physical activity. The outcome variable is the cumulative incidence rate of obesity, obtained from body mass index values and body fat assessed by triceps skinfold thickness. The independent variables are socio-demographic, contextual, eating habits, food frequency, intensity of physical activity and use of new technologies. Expected impact for public health: It is essential to implement preventive interventions at early ages and to follow its effects over time. Interventions involving diet and physical activity are the most common, being the most effective setting the school. The POIBA Project intervenes in both the school and family setting and focuses on the most disadvantaged groups, in which obesity is most pronounced and difficult to prevent.

The hydrological connectivity between the salt marsh and the sea was partially restored in a Mediterranean wetland containing isolated ponds resulting from former salt extraction and aquaculture activities. A preliminary assessment provided evidence that ponds farther from the sea hosted very large numbers of the endangered Spanish toothcarp, Aphanius iberus, suggesting that individuals had been trapped and consequently reach unnaturally high densities. In order to achieve both habitat rehabilitation and toothcarp conservation, efforts were made to create a gradient of hydrologically connected areas, including isolated fish reservoirs, semi-isolated, and connected salt marsh-sea areas that could allow migratory movements of fish and provide some protection for A. iberus. The fish community was monitored prior to, and for three years after rehabilitation. Results showed an increase in the number of fish species within semi-isolated areas (Zone A), whereas areas adjacent to the sea (Zone B) increased the number of marine species and decreased that of estuarine species (ES). Yet overall differences in fish assemblages were much higher between zones than among study years. Generalized linear models (GLMs) evidenced that distance to the sea was the most important variable explaining the local diversity of the fish community after restoration, with occasional influence of other factors such as temperature, and depth. The abundance of A. iberus was consistently higher in semi-isolated areas at greater distances from the sea, but a decline occurred in both zones and in isolated reservoir ponds after restoration efforts, which may be attributable to interannual differences in recruitment success and, to a lesser extent, to dispersal into adjacent habitats. A negative effect of restoration works on fish population cannot be excluded, but the final outcome of the intervention likely needs a longer period.

Objetivo: Conocer la prevalencia y los factores asociados al consumo de riesgo de alcohol entre los jóvenes de la Cataluña Central durante el curso 2011-2012 según el ámbito de residencia. Método: Estudio transversal, con una muestra de 1268 alumnos de 4° curso de ESO de la Cataluña Central. Resultados: El consumo de riesgo de alcohol es superior en los jóvenes que viven en un ámbito rural (59,6% versus 49,8%). Las borracheras de hermanos y amigos, tener expectativas positivas frente al consumo y haber comprado alcohol se asociaron al consumo de riesgo. En el ámbito rural se asociaron la situación familiar de convivencia diferente a la biparental y el bajo nivel académico, y en el ámbito urbano el alto nivel socioeconómico. Conclusiones: El consumo de riesgo de alcohol es muy superior entre los jóvenes del ámbito rural. Los principales factores asociados son los consumos de figuras del entorno familiar y escolar.

In this article we pretend to prove the relations between two lines of research and inno-vation in the teaching of history and social sciences, both have important points of contact, although they belong to different scientific traditions. One is the development of historical consciousness; the other is the so called education for the future. The most obvious relation-ship between both traditions is their conception of the time and the importance that is given to the concept of future. Historical consciousness is temporal consciousness and helps us to relate the past with the present and with our ideas and ideals about the future. Education for the future aims to analyze the images that society has built for the future and at the same time, help to build capacities to think of alternative or desirable futures and act accordingly with responsibility and social commitment. In our opinion, both traditions are becoming more and more closer, as the historical–temporal consciousness points strongly to the future–present, and the education for the future needs to think about the past and the learning of temporality.

El porcentaje de fracasos y recaídas en el tratamiento de la obesidad es alto. Siempre que sea posible, la prevención de la obesidad para modificar hábitos alimentarios y estilos de vida ha de ser la conducta preferente. Este trabajo pretender ofrecer un marco de evidencia sobre los componentes más efectivos de las intervenciones para el abordaje de la obesidad infantil, tanto de su prevención como de su reducción, cuando esta ya está instaurada. A partir de la literatura científica, se presentan los aspectos que debe contemplar la prevención, tanto universal como selectiva, de la obesidad infantil. Habida cuenta también de la controversia sobre los instrumentos de registro y control del problema, se aportan algunos criterios clarificadores. Finalmente, se diferencia el abordaje de la prevención del sobrepeso y la obesidad con una perspectiva comunitaria, ofreciéndose 2 protocolos breves que esquematizan un procedimiento básico a seguir.

Current knowledge about functional connectivity in obsessive-compulsive disorder (OCD) is based on small-scale studies, limiting the generalizability of results. Moreover, the majority of studies have focused only on predefined regions or functional networks rather than connectivity throughout the entire brain. Here, we investigated differences in resting-state functional connectivity between OCD patients and healthy controls (HC) using mega-analysis of data from 1024 OCD patients and 1028 HC from 28 independent samples of the ENIGMA-OCD consortium. We assessed group differences in whole-brain functional connectivity at both the regional and network level, and investigated whether functional connectivity could serve as biomarker to identify patient status at the individual level using machine learning analysis. The mega-analyses revealed widespread abnormalities in functional connectivity in OCD, with global hypo-connectivity (Cohens d: -0.27 to -0.13) and few hyper-connections, mainly with the thalamus (Cohens d: 0.19 to 0.22). Most hypo-connections were located within the sensorimotor network and no fronto-striatal abnormalities were found. Overall, classification performances were poor, with area-under-the-receiver-operating-characteristic curve (AUC) scores ranging between 0.567 and 0.673, with better classification for medicated (AUC = 0.702) than unmedicated (AUC = 0.608) patients versus healthy controls. These findings provide partial support for existing pathophysiological models of OCD and highlight the important role of the sensorimotor network in OCD. However, resting-state connectivity does not so far provide an accurate biomarker for identifying patients at the individual level.
