Proporciona información clara, sencilla y accesible sobre los procedimientos, requisitos y oportunidades que ofrece la contratación pública. Está especialmente pensada para apoyar a las entidades del TSC en su camino hacia una participación más activa en este ámbito, aprovechando las posibilidades que ofrecen las cláusulas sociales y los criterios de contratación responsable. Esta guía se ha desarrollado con tres objetivos específicos: Recoger y sintetizar información relevante sobre el sistema de contratación pública, enfocándose en las características y necesidades del TSC; Ofrecer contenidos accesibles y fáciles de entender, con el apoyo de recursos visuales como diagramas y gráficos que ayuden a clarificar conceptos; Incluir herramientas prácticas que faciliten el uso del manual y su aplicación directa en los procesos de licitación. Guía de acceso a la contratación pública para el Tercer Sector de la Comunicación es parte del Proyecto de I+D+i «Sostenibilidad del Tercer Sector de la Comunicación. Diseño y aplicación de indicadores» (SOScom), el cual comprende el diseño, validación y aplicación de un modelo de indicadores sintéticos y de un índice de sostenibilidad para los medios del Tercer Sector de la Comunicación (TSC). Además, incluye el análisis y difusión de distintas propuestas, medidas y buenas prácticas de cara a mejorar la viabilidad y resiliencia del sector. 2025-01-01T00:00:00Z http://hdl.handle.net/10498/40548 Corrigendum to ‘Consumer preferences towards the management of fish escapes from aquaculture: A choice experiment’(Marine Policy, (2026), 188, C, (107082), (S0308597X26000527), 10.1016/j.marpol.2026.107082) Perni Llorente, Ángel; Barreiro-Hurlé, Jesús; Ruiz Chico, José; Toledo-Guedes, Kilian The authors regret that the affiliations were incorrect in the original publication, as part of them should have been written in Spanish (i.e., the name of the universities involved in the research).

It is essential to continue exploring the factors associated with mathematical performance, including cognitive, attitudinal, and methodological aspects. Given the presence of open scientific questions, this study aimed to contribute to theoretical and empirical knowledge in mathematical cognition by comparing students from instructional contexts using a traditional approach with those from contexts using the Open Algorithm Based on Numbers (ABN) method. The comparison focused on general mathematical competence, specific mathematical skills, and cognitive and attitudinal factors. Another key objective was to assess the association of these cognitive and attitudinal factors with mathematical competence. The sample consisted of 244 upper primary school students, divided into two groups (ABN and non-ABN). Various mathematical skills, cognitive variables (short-term memory, working memory, fluid intelligence, and processing speed), and negative predisposition toward mathematics were measured. The study followed a ex post facto design, and available socioeconomic and educational indicators were examined to support the comparability of the groups. The results showed differences between instructional contexts, with students from contexts using the ABN methodology obtaining higher scores in most assessed mathematical skills. Positive correlations were found between cognitive factors and mathematical competence, while a negative correlation was observed with negative predisposition. Additionally, cognitive and attitudinal variables accounted for 48.7% of the variance in general mathematical competence. In conclusion, the findings highlight the relevance of instructional context, together with cognitive and attitudinal factors, for understanding mathematical performance in Primary Education, and should be interpreted cautiously given the associational rather than causal nature of the study. 2026-05-27T00:00:00Z http://hdl.handle.net/10498/40518 Beyond emotions: Social cognitive predictors of COVID-19 vaccination intentions before and after vaccine roll-out Manoli, Athina; Kyprianidou, Maria; Lamnisos, Demetris; Lubenko, Jelena; Presti, Giovambattista; Squatrito, Valeria; Constantinou, Marios; Nicolaou, Christiana; Papacostas, Savvas; Aydin, Gökçen; Yu Chong, Yuen; Chien, Wai Tong; Cheng, Ho Yu; Ruiz, Francisco; Garcia-Martin, Maria B.; Obando-Posada, Diana P.; Segura-Vargas, Miguel A.; Vasiliou, Vasilis S; McHugh, Louise; Höfer, Stefan; Baban, Adriana; Neto, David Dias; da Silva, Ana Nunes; Monestès, Jean-Louis; Álvarez Gálvez, Javier; Paez-Blarrina, Marisa; Montesinos, Francisco; Valdivia-Salas, Sonsoles; Ori, Dorottya; Kleszcz, Bartosz; Lappalainen, Raimo; Ivanovic´, Iva; Gosar, David; Dionne, Frederick; Merwin, Rhonda M.; Karekla, Maria; Gloster, Andrew T.; Kassianos, Angelos P. Understanding the drivers of COVID-19 vaccination intentions remains relevant as public health systems prepare for future pandemics. This study examined how emotional and social-cognitive factors influence COVID-19 vaccination intentions during two key phases of the COVID-19 pandemic: before (April-June 2020) and after (January-February 2021) vaccination rollout. A total of 586 adults completed an online survey assessing beliefs about COVID-19, self-efficacy to adhere to protective behaviours, perceived stress, affect, psychological flexibility, and prosociality. Self-efficacy, prosociality, psychological flexibility and positive affect significantly declined after vaccination rollout. Higher self-efficacy and perceived severity of the disease consistently predicted stronger vaccination intentions across time points. Perceived susceptibility was negatively associated with vaccination intention before, but not after rollout. The psychological variables were not significant predictors of intentions. These findings underscore the importance of social-cognitive factors, especially self-efficacy and perceived severity, in shaping vaccination-related decisions, with implications for designing effective communication strategies in future health emergencies. 2026-01-01T00:00:00Z
