    Digital Rights and Responsibility in Education: A Scoping Review

    Get PDF
    Studies on digital rights in education have both gained attention and provided a framework for research, policy and practice in educational research within the field of educational technology. The potential benefits we appreciate in Internet use are inseparable from the maximum risks involved. Faced with this responsibility, individuals demand that their rights and freedoms be guaranteed in the digital environment according to their various roles as students, teachers, families or staff. This scoping review selects and analyses 54 theoretical and empirical studies from the last decade (2013-2023), identifying the main topics investigated as privacy protection in online environments, right to digital security or cybersecurity, and right to digital education. The review underscores the need to guide efforts towards digital education for citizens because the legal regulation of rights and responsibilities is necessary but insufficient. The paper also makes arguments about acceptance, limitations and implications for teacher training.European Regional Development Fund’s 2014-2020 Operational Program, the Andalusian Government, and Spain’s Department of Economic Transformation, Industry, Knowledge and Universities (Project A.SEJ.46.UGR 2020)

We show that for every integer k with [ n 2 ] ≤ k ≤ n − 1 there is a nonsingular holomorphic foliation of dimension k on X all of whose leaves are closed and g-complete. The same is true if 1 ≤ k < [ n 2 ] provided that there is a complex vector bundle epimorphism T X → X × Cn−k . We also show that if F is a proper holomorphic foliation on Cn (n > 1) then for any Riemannian metric g on Cn there is a holomorphic automorphism Φ of Cn such that the image foliation Φ∗F is g-complete. The analogous result is obtained on every Stein manifold with Varolin’s density property.MCIN/AEI/10.13039/ 501100011033/, Spain: PID2020-117868GB-I00MCIN/AEI/10.13039/ 501100011033/, Spain: “Maria de Maeztu” Excellence Unit IMAG, CEX2020-001105-MEuropean Union: ERC Advanced HPDR, 101053085ARRS, Republic of Slovenia: P1-0291, J1-3005, N1- 0237Universidad de Granada/CBU

    Aedes albopictus in a recently invaded area in Spain: effects of trap type, locality, and season on mosquito captures

    Get PDF
    Mosquitoes are primary vectors of pathogens impacting humans, wildlife, and livestock. Among them, the Asian tiger mosquito, Aedes albopictus, stands out as an invasive species with a global distribution, having established populations on every continent except Antarctica. Recent findings incriminate Ae. albopictus in the local transmission of several pathogens causing human diseases, including dengue, chikungunya, and Zika viruses and worm parasites as Dirofilaria. In Spain, the establishment of Ae. albopictus occurred in 2004 and it rapidly expanded, currently reaching southern provinces and creating novel epidemiological scenarios in recently invaded areas. In this study, we conducted captures of Ae. albopictus from May to November 2022 in two provinces, Granada and Malaga, situated near the current edge of the species' expanding range in Spain. The objective was to identify the primary factors influencing their captures in these regions. Mosquitoes were captured using BG-Sentinel traps baited with CO2 and BG-Lure, and miniature CDC-UV traps in five different localities. Our findings underscore the influence of both extrinsic factors, such as locality, and intrinsic factors, including mosquito sex, on the abundance of captured Ae. albopictus. A higher abundance of Ae. albopictus was observed in the Malaga province compared to localities in the Granada province. Furthermore, similar numbers of Ae. albopictus mosquitoes were captured in more urbanized areas of Granada, while the lowest counts were recorded in the less urbanized area. These results were compared to captures of another common species in the area, specifically Culex pipiens. Overall, these results represent the first monitoring of invasive Ae. albopictus in the area and are discussed in the light of the potential importance of the species as a nuisance for humans and vectors of pathogens of public health relevance.This study was financed by the PID2020-118205GB-I00 grant to JMP funded by MCIN/AEI/ Additional support derived from the CNS2022-135993 grant of the Ministerio de Ciencia e Innovación (MCIN/AEI/ with funding from European Union NextGenerationEU.

    The Daugavet equation for polynomials on C⁎-algebras and JB⁎-triples

    Get PDF
    We prove that every JB∗-triple E (in particular, every C∗- algebra) satisfying the Daugavet property also satisfies the stronger polynomial Daugavet property, that is, every weakly compact polynomial P : E −→ E satisfies the Daugavet equation IdX +P = 1 + P . The analogous conclusion also holds for the alternative Daugavet propert

    Intra-facility equity in discrete and continuous p-facility location problems

    Get PDF
    We consider facility location problems with a new form of equity criterion. Demand points have preference order on the sites where the plants can be located. The goal is to find the location of the facilities minimizing the envy felt by the demand points with respect to the rest of the demand points allocated to the same plant. After defining this new envy criterion and the general framework based on it, we provide formulations that model this approach in both the discrete and the continuous framework. The problems are illustrated with examples and the computational tests reported show the potential and limits of each formulation on several types of instances. Although this article is mainly focused on the introduction, modeling and formulation of this new concept of envy, some improvements for all the formulations presented are developed, obtaining in some cases better solution times.Project TED2021-130875B-I00, supported by MCIN/AEI/ 10.13039/ 501100011033 and the European Union ‘‘NextGenerationEU/PRTR’’Research project PID2022- 137818OB-I00 (Ministerio de Ciencia e Innovación, Spain)Agencia Estatal de Investigación (AEI), Spain: PID2020-114594GB-C2; Regional Government of Andalusia, Spain P18-FR-1422 and B-FQM-322-UGR20 (ERDFIMAG-Maria de Maeztu, Spain grant CEX2020-001105-M/AEI/10.13039/ 501100011033Funding for open access charge: Universidad de Granada / CBU

    Evaluating the whiteness of spectroscopy-based non-destructive analytical methods – Application to food analytical control

    Get PDF
    Recent advancements in analytical chemistry in the food quality field have emphasized ecofriendly analytical techniques eschewing chemicals and solvents. Various methodologies exist for assessing the sustainability of analytical methods, however none has provided guidance for appraising non-destructive methods, especially predevelopment. Among these, the RGB approach stands out, evaluating method colour via three main criteria: analytical performance, environmental impact, and practical efficiency. This framework offers a comprehensive evaluation, aiming for a "white" colour denoting excellence across all three categories. This article introduces an adapted RGB method for ex-ante evaluation of new non-destructive analytical methods pre-development. It outlines key steps for evaluating method "whiteness". As a guiding example, the approach was applied to three analytical methods focussed on quality and authenticity control of edible vege- table oils utilizing solvent-free spectroscopic techniques. Results underscored a priori feasibility assessment value, aligning evaluative objectives with intended method goals.Project (ref.: CPP2021-008672), funded by MCIN/AEI/501100011033 (Spanish Ministry of Science and Innovation)European Union NextGenerationEU/PRTR"Funding for open access charge: Universidad de Granada / CBU

However, the surging demand for olive oil has led to its susceptibility to adulteration with cheaper oils, such as soybean, peanut, hazelnut, and sunflower oil. Notably, extra virgin olive oil (EVOO), commanding a premium price, is particularly prone to adulteration with lower-cost alternatives. This adulteration poses a significant risk to health, necessitating the development of methods to detect and separate these impurities, thereby ensuring the quality and safety of olive oil. In order to address this concern, chromatographic techniques have emerged as pivotal tools in the purification and detection of adulterants in olive oil. Commonly employed methods include Thin Layer Chromatography (TLC), Gas Chromatography (GC), Liquid Chromatography (LC), and High-Performance Liquid Chromatography (HPLC). These techniques play a crucial role in differentiating between pure and impure olive oil in the market. This article focuses on the most prospective chromatographic methods for the detection and identification adulteration in olive oil. The outcomes of this research have the potential to pave the way for new directions in food security research, contributing to overall sustainability. Moreover, the insights gained from this study can be valuable for young students, serving as a concise reference for analytical methods in this field.Resumen: El aceite de oliva destaca como uno de los aceites más beneficiosos para la salud humana, ofreciendo medidas preventivas contra un espectro de problemas de salud, incluyendo problemas cardiovasculares, cáncer, osteoporosis y diversas enfermedades crónicas. Sin embargo, la creciente demanda de aceite de oliva ha llevado a su susceptibilidad a la adulteración con aceites más baratos, como el de soja, cacahuate, avellana y girasol. Es importante destacar que el aceite de oliva virgen extra (AOVE), que tiene un precio premium, es particularmente propenso a la adulteración con alternativas de menor costo. Esta adulteración representa un riesgo significativo para la salud, lo que hace necesario el desarrollo de métodos para detectar y separar estas impurezas, asegurando así la calidad y seguridad del aceite de oliva. Para abordar esta preocupación, las técnicas cromatográficas han surgido como herramientas fundamentales en la purificación y detección de adulterantes en el aceite de oliva. Los métodos comúnmente empleados incluyen la Cromatografía en Capa Fina (TLC), la Cromatografía de Gases (GC), la Cromatografía Líquida (LC) y la Cromatografía Líquida de Alta Resolución (HPLC). Estas técnicas desempeñan un papel crucial en diferenciar entre aceite de oliva puro e impuro en el mercado. Este artículo se centra en los métodos cromatográficos más prometedores para la detección e identificación de adulteraciones en el aceite de oliva. Los resultados de esta investigación tienen el potencial de abrir nuevas direcciones en la investigación de seguridad alimentaria, contribuyendo a la sostenibilidad general. Además, las percepciones obtenidas de este estudio pueden ser valiosas para los estudiantes, sirviendo como una referencia concisa para los métodos analíticos en este campo.The research received financial support from the "SUSTAINABLE" project, which is funded by the European Union's Horizon 2020 Project H2020-MSCA-RISE-2020, under Grant Agreement 101007702
