An innovative platform to promote social media literacy in school contexts
2021
In spite of the impressive number of adolescents using social media, only a minority is aware of the risks associated with the use of the Internet. Hate speech, violation of personal rights, psychological attacks, deceiving people with fake accounts, as well as cyberbullying, harassment and insults are some examples of toxic content that can jeopardize adolescent well-being on the Web. Social Media literacy paths in school contexts provide students with the proper defence instruments to face these problems. Furthermore, it is important to underline the role of social media on both the intrinsic and extrinsic motivation of adolescents which has short-and long-term influences when using these…
Digital participation in service environments among senior electricity consumers in Finland
2018
Research to date suggests that older adults engage with digital technologies less frequently than young adults. Studies typically focus on chronological age, ignoring the effects of life course factors on the adoption and use of digital technologies. By utilising multiple triangulation, the article investigates the role of age and life course stage in the usage of an electricity company's online services among senior consumers. The data are derived from an internet-based survey study (N = 1366) and six focus group discussions involving Finnish electricity consumers (N = 29). The results suggest that online consumers aged 50 and over utilise electricity company online services more frequentl…
Paleontología y ambientes del Triásico Medio en el sector noroccidental de la cordillera ibérica (provs. de Soria y Guadalajara, España)
1991
El Triásico Medio del sector noroccidental de la Cordillera Ibérica está compuesto por dos formaciones carbonáticas, que se corresponden con la unidad carbonática superior del Muschelkalk, y que hacia el NW pasan lateralmente a una formación terrígena. El registro fósil se encuentra en ambos tipos de formaciones. Tanto el estudio tafonómico como sedimentológico, permiten inferir la presencia de elementos acumulados que podrían corresponder a asociaciones autóctonas, compuestas en su mayoría por bivalvos infaunales de medios marinos someros y sometidos a fuerte influencia de terrígenos. Se caracterizan en la zona tres asociaciones faunísticas: 1. Asociación CostatoriaLyriomyophoria, que apar…
Understanding adults’ strong problem-solving skills based on PIAAC
2017
Purpose Research has shown that the problem-solving skills of adults with a vocational education and training (VET) background in technology-rich environments (TREs) are often inadequate. However, some adults with a VET background do have sound problem-solving skills. The present study aims to provide insight into the socio-demographic, work-related and everyday life factors that are associated with a strong problem-solving performance. Design/methodology/approach The study builds on large-scale data of the Programme for the International Assessment of Adult Competencies (PIAAC) and gives insight into VET adults (N = 12,929) with strong problem-solving skills in 11 European countries. Find…
Análisis de la construcción de entornos virtuales en los “Centros Educativos Inteligentes”
2013
El propósito de este artículo es plantear una metaevaluación de los primeros resultados obtenidos en un proyecto de investigación sobre la iniciativa ministerial Escuela 2. 0. en la que han participado 12 universidades. Nuestra aportación se centra en el análisis de cuatro estudios de casos, todos ellos Centros Educativos Inteligentes de la Comunidad Valenciana. Con los datos e información recabada se inicia el tratamiento de la muestra con una metodología mixta para analizar cómo estos centros se van transformando progresivamente en entornos virtuales de enseñanza y aprendizaje en colaboración. Transformación en la que la micropolítica de estas organizaciones es tanto o más relevante que l…
Past aquatic environments in the Levant inferred from stable isotope compositions of carbonate and phosphate in fish teeth
2019
Here we explore the carbon and oxygen isotope compositions of the co-existing carbonate and phosphate fractions of fish tooth enameloid as a tool to reconstruct past aquatic fish environments and harvesting grounds. The enameloid oxygen isotope compositions of the phosphate fraction (δ18OPO4) vary by as much as ~4‰ for migratory marine fish such as gilthead seabream (Sparus aurata), predominantly reflecting the different saline habitats it occupies during its life cycle. The offset in enameloid Δ18OCO3-PO4 values of modern marine Sparidae and freshwater Cyprinidae from the Southeast Mediterranean region vary between 8.1 and 11.0‰, similar to values reported for modern sharks. The mean δ13C …
L’innovazione tecnologica e il Faculty Development.
2023
La crisi pandemica ha accelerato la diffusione di ambienti di apprendimento caratterizzati dall'uso intensivo della tecnologia. Questa novità rappresenta un obiettivo trasversale della professionalizzazione del docente universitario, con una particolare declinazione sul versante pedagogico-didattico-valutativo quale questione strategica per lo sviluppo dell’alta formazione. Il contributo illustra i risultati di una ricerca condotta con 119 docenti universitari neoassunti e 20 Direttori di dipartimento. La finalità della ricerca è stata, da una parte, rilevare la percezione dei docenti neoassunti relativa alle proprie competenze didattiche, metacognitive e valutative, con riferimento alla di…
Unveiling distribution patterns of freshwater phytoplankton by a next generation sequencing based approach.
2012
The recognition and discrimination of phytoplankton species is one of the foundations of freshwater biodiversity research and environmental monitoring. This step is frequently a bottleneck in the analytical chain from sampling to data analysis and subsequent environmental status evaluation. Here we present phytoplankton diversity data from 49 lakes including three seasonal surveys assessed by next generation sequencing (NGS) of 16S ribosomal RNA chloroplast and cyanobacterial gene amplicons and also compare part of these datasets with identification based on morphology. Direct comparison of NGS to microscopic data from three time-series showed that NGS was able to capture the seasonality in…
Research focusing on plant performance in constructed wetlands and agronomic application of treated wastewater – A set of experimental studies in Sic…
2019
Constructed wetlands are sustainable technologies for the treatment of wastewater. These biological systems have been widely studied throughout the world for more than 30 years; however, most studies have focused on the effects of design and engineering on pollutant removal from wastewater. Undoubtedly, agro-technical aspects have been given too little consideration by research. This paper reports the main results of a set of experiments carried out on two pilot horizontal subsurface flow systems in Sicily (Italy). Festuca, Lolium and Pennisetum spp. in combination and three emergent macrophytes-Arundo donax L., Cyperus alternifolius L. and Typha latifolia L.-alone, were assessed. The aim o…
Carbon stock increases up to old growth forest along a secondary succession in Mediterranean island ecosystems.
2019
The occurrence of old-growth forests is quite limited in Mediterranean islands, which have been subject to particularly pronounced human impacts. Little is known about the carbon stocks of such peculiar ecosystems compared with different stages of secondary succession. We investigated the carbon variation in aboveground woody biomass, in litter and soil, and the nitrogen variation in litter and soil, in a 100 years long secondary succession in Mediterranean ecosystems. A vineyard, three stages of plant succession (high maquis, maquis-forest, and forest-maquis), and an old growth forest were compared. Soil samples at two soil depths (0-15 and 15-30 cm), and two litter types, relatively undec…
