    El crecimiento exponencial del Derecho internacional desde la perspectiva de su contenido sustantivo ha tenido entre sus consecuencias el planteamiento de un riesgo de fragmentación del mismo en distintos sub-ordenamientos que ha sido advertido por la doctrina y ha merecido atención por parte de la Comisión de Derecho Internacional. Ese riesgo resulta entre otros factores del hecho de que los distintos ámbitos materiales cubiertos por el ordenamiento jurídico internacional no se conforman en la práctica como compartimentos estancos, sino que constituyen distintos planos de una misma realidad interdependiente. En consecuencia, su enfoque fragmentado desaprovecha la oportunidad de establecer sinergias entre la acción desarrollada en cada uno de esos ámbitos, aprovechando los posibles avances que pudieran registrarse en unos para progresar en el desarrollo de otros. O, lo que es incluso peor, genera respuestas desde el Derecho a los problemas existentes en un ámbito determinado que pueden dificultad el logro de los objetivos pretendidos en otros ámbitos

    Este estudio tuvo como objetivo analizar el impacto de la gamificación como estrategia pedagógica en la adquisición de competencias profesionales vinculadas a la Investigación-Acción Participativa (IAP) en estudiantes del Grado en Trabajo Social de la Universidad de Zaragoza. Para ello, se diseñó una experiencia didáctica gamificada, aplicada durante un semestre, basada en misiones, retos, recompensas simbólicas y narrativas colaborativas. La metodología combinó enfoques cuantitativos y cualitativos. Se utilizaron cuestionarios pretest y postest con escala Likert, registros de participación, rúbricas de evaluación formativa y un grupo focal final. El análisis cuantitativo se realizó mediante estadística descriptiva e inferencial, incluyendo ANOVA de medidas repetidas e intervalos de confianza; mientras que los datos cualitativos se codificaron temáticamente. Los resultados mostraron una mejora estadísticamente significativa en dimensiones como el trabajo en equipo, la planificación participativa y la comunicación efectiva, así como una mayor implicación crítica del alumnado en su proceso de aprendizaje. Se concluye que la gamificación, cuando es diseñada con intencionalidad pedagógica, puede potenciar la enseñanza de metodologías complejas como la IAP, facilitando un aprendizaje transformador. El estudio recomienda avanzar en la formación docente en diseño gamificado y en la integración curricular de metodologías activas en la educación superior.

    Valorizing Ibericus traditional melons for organic farming: Crop limitations, use of grafting, and impact on agronomic performance and fruit quality

    No full text
    Melon (Cucumis melo L.) is a major crop in Spain, where traditional cultivars of the Ibericus group, selected by local farmers over centuries, are still grown for local markets and self-consumption. These landraces are valuable for organic and sustainable farming, but their productivity is limited by biotic and abiotic stresses. Understanding the limiting factors is essential to guide cultural or genetic strategies that help mitigate their impact. This study evaluated the agronomic performance and fruit quality of 17 Ibericus cultivars, cultivated as non-grafted and grafted onto commercial Cucurbita and experimental Cucumis rootstocks. Trials were conducted over two years in three contrasting organic fields: (i) a non-stressed location without prior melon cultivation, (ii) a pathogen and virus-prone location with a long melon-growing history, and (iii) a site with saline conditions. Viral (WMV, CMV, CABYV, ToLCNDV), powdery mildew, and soilborne pathogens (Macrophomina phaseolina, Neocosmospora spp., Fusarium spp.) severely affected yield. While salinity had minimal impact on yield, it increased SSC in Piel de Sapo, Amarillo, and Rochet cultivars. Under extreme salinity and low rainfall, pathogen dynamics changed, affecting plant development. Grafting reduced plant mortality and increased yield across cultivars, though rootstocks varied in their pathogen resistance profiles. Cucumis rootstocks, especially F1Pat81, maintained fruit quality better than Cucurbita. Varieties 03PS ('Piel de Sapo'), 22AM-GO ('Amarillo'), and 32BL ('Blanco') demonstrated favourable performance under saline conditions, particularly when grafted onto F1Pat81 or Cucurbita rootstocks, and are recommended for organic farming. Overall, traditional Ibericus melons demonstrate strong potential for organic systems; however, breeding for improved pathogen resistance and rootstock optimization remains essential to promote their cultivation

    Rethinking the fight against pig-related human salmonellosis in the European union

    No full text
    The prevalence of human salmonellosis associated with pork products remains a significant concern for public health authorities within the European Union. Despite the implementation of national programs in some member states with the objective of controlling the infection of Salmonella in farms, the proportion of human cases involving swine-associated Salmonella serotypes has remained constant in recent years, and the majority of these programs were either discontinued or reduced to biosecurity guidance. This article discusses the reasons for the lack of success of these programs, including the focus on the growing-finishing period without consideration of earlier stages of production, the structure of the pig sector, the limited and unrepresentative sampling carried out in the programs, and the use of imperfect serological tests, which have likely resulted in biased estimates of the true health status of the herds. A potential comprehensive approach is proposed, based on predicting the risk of Salmonella shedding prior to the arrival of pigs at the slaughter. This knowledge would be combined with the administration of on-farm additives (i.e. organic acids, bacteriophages) during the days prior to slaughter. It would help to reduce shedding in those batches with a high risk of shedding and decrease slaughter environmental contamination. Furthermore, this approach would contribute to obtain more accurate information regarding the Salmonella status of the pig farms

    Polymeric dye-loaded electrospun fibers for antimicrobial photodynamic therapy

    As an alternative to the extensive use and misuse of antibiotics, antimicrobial photodynamic therapy stands out as a non-selective, broad-spectrum, locally and spatially controlled antimicrobial therapy. Reactive oxygen and nitrogen species, generated by appropriate light on specific photosensitizers in the presence of tissue oxygen, cause rapid bacterial damage with reduced chances for bacteria to develop adaptive mechanisms of acquired or genetic resistance. Herein, we developed a light-responsive advanced wound dressing based on electrospun polycaprolactone (PCL) nanofibers decorated with PLGA microparticles (MPs) encapsulating a polymethine cyanine dye (Br-CY5). This bilayer system was designed to enable bacterial inactivation upon light irradiation while providing sustained dye release and mechanical stability suited for chronic wound environments. The hybrid dressing was evaluated against Staphylococcus aureus, which is a bacterial pathogen commonly present on chronic infected wounds, addressing a 99.9 % reduction in the bacterial load after irradiating the dressing with a 640 nm LED for 15 min. Additionally, the cytotoxicity of the free dye and the developed dressing was assessed on various eukaryotic cell lines to ensure cytocompatibility. These results highlight the potential of this bilayered photodynamic system as an effective and safe antimicrobial wound dressing for managing chronic infections

    Clinical Variability and Genotype–Phenotype Correlation in Spanish Patients with Type 1 Gaucher Disease: A Focus on Non-c.[1226A>G]; [1448T>C] Genotypes

    The clinical heterogeneity of type 1 Gaucher disease (GD1) underscores the limited correlation between the GBA1 genotype and phenotype. This study examined GD1 patients from the Spanish Gaucher Disease Registry carrying heterozygous GBA1 genotypes distinct from NM_000157: c.[1226A>G](N370S); [1448T>C](L444P). Among 374 patients with GD1, 195 (52.1%) had alternative heterozygous combinations, including variants corresponding to severe (37.9%) or moderate (42.1%) mutation, whereas only 20% patients harbored mild variants—all of them in combination with N370S. Descriptive statistics and predictive models based on logistic regression and decision trees were applied. Patients carrying N370S with a different L444P variant showed significantly higher rates of advanced bone disease (59.9%) compared to those with homozygous N370S (38.3%) or N370S; L444P (41.0%) (p = 0.002). Decision tree analysis identified the bone marrow burden score (S-MRI) as the strongest predictor of osteopenia/osteoporosis at diagnosis. Genotype also emerged as a key discriminator for Parkinson’s disease: patients with non-N370S; L444P genotypes showed a markedly higher likelihood of developing Parkinsonism. Overall, GD1 patients with genotypes other than N370S; L444P present more severe phenotypes, particularly with greater skeletal involvement and neurological complications. These findings highlight the importance of genotype stratification and predictive modeling in improving risk assessment and clinical management in GD1

    El Trust Joyero de Zaragoza, "la casa preferida por las personas inteligentes y de buen gusto"

    Get PDF
    Con el inicio de la Edad Contemporánea, Europa asistió al nacimiento de nuevos espacios comerciales, en buena medida vinculados a la formación de la urbe decimonónica y a la aparición de nuevos ritos cotidianos y formas de consumo. Uno de esos nuevos establecimientos fueron los almacenes de joyería, platería y relojería que, bajo la denominación de El Trust, se caracterizaron por la elegancia de sus instalaciones. Los primeros fundados en España abrieron sus puertas en Madrid en 1906 y, dos años después, se instalaron en Zaragoza. En este artículo se pretende trazar la historia de El Trust de Zaragoza y valorar su importancia como lugar de consumo de objetos suntuarios. At the beginning of the contemporary era, Europe witnessed the emergence of new commercial spaces, largely connected to the formation of the nineteenth-century city and to new everyday rituals and ways of consumption. Among those novel establishments were the jewellery, silver and watch shops, which, under the name of El Trust, were characterised by the elegance of their premises. The first ones founded in Spain opened their doors in Madrid in 1906 and, two years later, they settled in Zaragoza. This article aims to outline the history of El Trust in Zaragoza and to emphasise the importance of the establishment as a place for the consumption of sumptuary objects

    Remote monitoring of rock art shelters: an innovative application in the Cultural Park of Albarracín

    Get PDF
    The Sierra de Albarracín (Teruel, Spain) hosts notable post-Palaeolithic rock art, including the Toros del Prado del Navazo shelter. Although the Rock Art of the Mediterranean Arc is a World Heritage Site, its conservation faces environmental and human threats. Since 2013, monitoring in Aragón’s cultural parks has depended on periodic on-site data collection, limiting timely analysis. The integration of Internet of Things (IoT) technology at Toros del Prado del Navazo has improved conservation by enabling continuous remote environmental monitoring. This reduces the need for physical visits, lowering annual greenhouse gas emissions by 75% (from 197.20 to 49.30 kg CO₂eq) and minimising data gaps from 36% with traditional dataloggers to 5.9% in this particular case. IoT-based diagnostics allow faster decision-making, enhancing the preservation of rock paintings and promoting a sustainable, integrated management model for long-term protection of cultural heritage
