A scoping review of the research evidence of the developmental assets model in Europe
Get PDFIntroduction: Positive Youth Development (PYD) is a strength-based perspective
that focuses on the resources to promote a successful transition to adulthood,
derived from the Relational Developmental Systems theory. In this line, the
Developmental Assets (DA) model focuses on describing the personal resources
(Internal Assets) and contextual resources (External Assets) that help to reach
PYD. Most research from this approach has been carried out in United States
and, to a lesser extent, in the European continent. The aim of this scoping review
was to examine the evidence collected for the DA model in Europe.
Methods: Web of Science database was used to search for articles published
between 2013 and February 2024. Initially, there were 55 possible articles to
be included, but after applying the exclusion criteria, this number was reduced
to 11.
Results: The findings suggested that the evidence for DA in Europe was in line
with North American research, so that a higher presence of DA was related to
higher well-being, better psychological adjustment, and lower risk behaviors.
Internal Assets were the most influential assets, with the Positive Identity category
being especially remarkable. Commitment to Learning and Social Competencies
were also highlighted in the studies included in the review. Concerning External
Assets, Positive Boundaries-expectations and Empowerment were emphasized
as protective factors in youth development. These assets were found to present
a protective effect against risk behaviors and were positively associated with PYD
and socioemotional skills.
Discussion: Thus, these findings support the applicability of the DA framework
in promoting PYD in European context, and some intervention strategies are
discussed considering cultural diversityThe author(s) declare that financial support was received for the research, authorship, and/or publication of this article.

The Educational Potential of Video Games: Its Evaluation Through a Rubric
Get PDFEl videojuego es un recurso de ocio muy extendido asociado a entretenimiento, distensión y evasión mediante el juego. La investigación indaga sobre su potencial educativo. El objetivo del estudio es aportar una rúbrica capaz de evaluar la educatividad de cualquier videojuego. No se tiene constancia de una herramienta comparable aplicable a cualquier videojuego. Se optó por una metodología cualitativa y fenomenográfica. Se realizaron 40 entrevistas a maestros y a expertos de la industria del videojuego. De la revisión teórica y el análisis de los testimonios se obtuvo como resultado la herramienta CEV 5* («Clasificación Educativa de Videojuegos 5*»). La conclusión más relevante fue que el potencial educativo de un videojuego es una información evaluable y transferible a evaluadores de videojuegos, padres, profesores, usuarios, técnicos de la industria del videojuego y la sociedad en general. Así, el CEV 5* puede servir de referencia para el diseño y consumo del recurso, así como para un mayor discernimiento de hasta dónde puede un videojuego llegar en la educación de una persona. Su intención práctica es aportar el dato de su educatividad de un modo fácil e intuitivo: de 0 a 5 estrellas. Podría ser un modo de que usuarios, educadores, empresas y la sociedad en general puedan ser más conscientes del potencial formativo de cualquier videojuego, para su diseño, uso, compraventa, selección, etcVideo games are a widespread leisure resource associated with entertainment, relaxation and escape through play. The research questions its educational potential. The aim of the study is to provide a rubric capable of evaluating the educational potential of any video game. There is no record of a comparable tool applicable to any video game. A qualitative and phenomenographic methodology was chosen. Forty-two interviews were conducted with teachers and experts from the video game industry. From the theoretical review and the analysis of the testimonies, we obtained as a result the ECV 5* (“Educational Classification of Video games 5*”) tool. The most relevant conclusion was that the educational potential of a video game is evaluable and transferable information.

Its practical intention is to provide the data of its educational value in an easy and intuitive way: from 0 to 5 stars. It could be a way for users, educators, companies and society in general to be more aware of the educational potential of any video game, for its design, use, purchase and sale, selection, etcPedagogí
Las donaciones de obra impresa en el periodo parlamentario del trienio liberal en España
Get PDFEl Trienio Liberal fue el primer periodo de monarquía parlamentaria en España. Un primer intento de eliminar el yugo absolutista del Antiguo Régimen. En este marco legislativo del primer cameralismo, y a lo largo de los debates de las diferentes leyes que la prolífica acción de los diputados realiza, llegan al hemiciclo como donaciones 83 obras de autoría nacional y otras 13 de escritores extranjeros. Con este trabajo hemos realizado una descripción, tanto cuantitativa como cualitativa, de los textos que, en su mayoría, van nutriendo a las comisiones que tuvieron el encargo de realizar la legislación que se gestaba en la cámara. El hecho de que los diputados no se limitaran a aceptar las obras que iban llegando, sino que las distribuyeran entre las comisiones, sugiere que se preocuparon por elaborar leyes de calidad, depuradas no solo a partir del debate del hemiciclo, sino también a través de lecturas especializadas en cada materia.Enfermerí

Experimental study of 6He Coulomb breakup as an indirect measurement of 4He(2n,γ)6He reaction rate for the astrophysical r-process
Get PDFIn this work, we report the measurement of elastic and Coulomb break-up channels in 6He+208Pb collisions at Elab = 19.3 MeV, close to the Coulomb barrier of this system ∼ 19 MeV. In the context of the astrophysical r-process, the reaction 4He(2n,γ)6He has been proposed to be a key reaction in the path of synthesizing seed nuclei for the r-process, as 12C, in an environment composed mainly of alpha particles and neutrons. Based on a theoretical approach for treating three body reactions by means of which its reaction rate can be inferred, our experimental approach aims to obtain an indirect measurement of the reaction rate of 4He(2n,γ)6He by measuring the Coulomb breakup of 6He under the intense electric field produced by a 208Pb target nucleus. The experiment was carried out at the TriSol facility operated in the Nuclear Science Laboratory of the University of Notre Dame, USA, which delivered a 6He beam together with other contaminants. Particular care must be taken for the alpha particles produced in the production reactionPart of the collaboration was partially or totally supported by the National Science Foundation under Grant No. OISE-1927130 (IReNA, International Research Network for Nuclear Astrophysics, https://www.irenaweb.org/) in the participation of the experiment at NSL-University of Notre Dame.

Intolerance of Uncertainty, Job Satisfaction and Work Performance in Turkish Healthcare Professionals: Mediating Role of Psychological Capital
Get PDFObjective: Psychological capital refers to internal resources including self-efficacy, hope,
optimism and resilience to overcome adverse life events. The current study sought to
examine the mediating role of psychological capital in the relationship between intolerance
of uncertainty and job satisfaction and work performance in healthcare professionals.
Methods: Participants were 302 healthcare professionals [48% females; M(SD)age = 34.0
(7.5)] and completed measures of intolerance of uncertainty, psychological capital, work
performance, and job satisfaction.
Results: The findings indicated that intolerance of uncertainty was negatively correlated
with psychological capital, work performance, and job satisfaction, whereas psychological
capital was positively correlated with job satisfaction and work performance. More
importantly, the findings revealed that these relationships were mediated by
psychological capital.
Conclusion: The results provide several contributions that help to understand the role of
psychological capital in the relationship between intolerance to uncertainty and job
satisfaction and work performance.Sociología, Trabajo Social y Salud Públic
Maternal Perception of Pregnancy Loss: Protocol for a Thematic Synthesis
Get PDFIntroduction: The number of women who present this perineal loss is high. Identifying the existing knowledge about the women’s
experiences and perceptions of pregnancy loss is essential to understand the impact of the phenomenon on women. This identification
is also crucial to adapt and improve the healthcare provided.
Subjects and Methods: A systematic literature review, meta-synthesis, of qualitative studies will be developed with the goal of
obtaining a comprehensive understanding of mothers’ perception of pregnancy loss and identifying their specific support needs.
Inclusion Criteria: This review will consider qualitative investigations that study the perceptions or experiences of adult women who
have suffered prenatal loss. All studies published in English, Spanish or Portuguese between January 1, 2012, and December 31, 2022
will be considered. This systematic review will follow the Joanna Briggs Institute statement for systematic reviews of qualitative
design. The Psychology and Behavioral Sciences Collection, Scopus, CINAHL®, MEDLINE® and Cochrane Database of Systematic
Reviews (CDRS) databases will be utilized for research. Data extraction will be performed in-peers by the researchers, using the
Joanna Briggs Institute model. Finally, the available data will be analysed using a meta-aggregation approach.
Conclusion: A better understanding of this phenomenon will be useful, identifying, on the one hand, the support needs of women
who have suffered fetal loss and, on the other hand, also identifying the support and interventions that can be implemented by health
professionals.Sociología, Trabajo Social y Salud Públic
Extended Lipkin model: Proposal for implementation in a quantum platform and machine learning analysis of its phase diagram
Get PDFBackground: In recent years, the implementation of nuclear physics models in quantum computers has emerged as a promising and novel area of research. Simultaneously, the study of quantum shape phase transitions in nuclear models has gained significant attention. Specifically, the phase diagram of the interacting boson approximation (IBA) has been extensively explored, particularly in connection with large-particle-number-limit considerations. Interestingly, the extended Lipkin model (ELM) serves as a valuable alternative for mimicking the IBA phase diagram and holds the advantage of being more straightforward to implement within a quantum computing platform.
Purpose: We explore the ELM and provide: (i) calculations of the ground-state energy using a variational quantum eigensolver; (ii) a comprehensive formulation for implementing the dynamics of the ELM within a quantum computing platform, enabling the experimental exploration of the IBA phase diagram for systems with a small number of particles; and (iii) a determination of the phase diagram of the model using different machine learning (ML) methods. We note that in the ELM, unlike the usual Lipkin model, both first- and second-order
quantum shape phase transitions take place depending on the model parameters.
Methods: Initially, we employ the adaptive derivative-assembled pseudo-Trotter ansatz variational quantum eigensolver (ADAPT-VQE) to calculate the ground-state energy of the ELM. Next, we introduce the essential formulation and procedures required to implement this model effectively in a quantum computing environment. Finally, we use ML techniques to identify the different phases and critical points of the ELM.
Results: We successfully reproduce the ground-state energy of the ELM across the complete phase space of the model using the ADAPT-VQE algorithm. We provide the necessary framework for implementing the ELM in a quantum computing platform, ensuring that the model can be executed with controlled errors. Finally, we obtain meaningful ML predictions that allow us to determine the phase diagram of the model.
Conclusions: Our findings offer compelling evidence that the implementation of a nuclear model like the ELM in a quantum computing environment is not only feasible but can also be achieved with manageable error rates. This realization opens the door to detailed experimental investigations of the phase diagram of the ELM (and indirectly of the IBA) in a quantum computer, further advancing our understanding of quantum shape phase transitions and nuclear structure.Ciencias Integrada

Get PDFEsta investigación explora el papel de los recursos didácticos inclusivos en un taller de resolución de
problemas con alumnado con Trastorno del Espectro Autista-Síndrome de Asperger. Siguiendo una
metodología exploratoria y de observación, las unidades de información extraídas de las
videograbaciones de las sesiones del taller y las producciones del alumnado han permitido analizar el
tipo de recurso empleado y cómo han influido en el taller, considerando sus funciones y su carácter
inclusivo. La estructuración visual, propiciada a través de distintos formatos de representación, ha
resultado un elemento clave para que los participantes gestionen, comprendan, ejecuten y revisen su
proceso de resolución de problemas. Se han evidenciado distintas funciones inclusivas de los recursos
y un vínculo con los principios del Diseño Universal de Aprendizaje, aunque también la necesidad de
adaptar y diseñar los recursos para propiciar el desarrollo de estrategias en otros contextos de
enseñanza, como el aula ordinaria de educación primaria.This research explores the role of inclusive teaching resources in problem-solving with students with
Autism-Asperger Syndrome. Following an exploratory and observational methodology, units of
information from the students’ productions and video recordings are analysed regarding the type of
resource used, its influence on the participants’ decision-making, their functions and inclusive
character. Resources deployed visual structures, which have become key elements for the
participants to manage, understand, execute, and review their own problem-solving process. The use
of the materials has evidenced several inclusive resources functions and a connection to the
principles of Universal Design for Learning, but also the need for adapting and designing them to
promote strategies in other teaching contexts, such as the ordinary classroom of primary education.PedagogíaDidácticas IntegradasPedagogí
Radiological assessment of both unperturbed and agricultural soils from southern Ecuador
Get PDFThe radiological background in soils across various areas in Southern Ecuador, such as Vilcabamba, Loja, Palanda, Catamayo, and Taquil, was studied to understand the impact of agriculture and fertilizer usage on soil radiological composition. Areas impacted by agricultural activities alongside reference areas unaffected by human intervention were chosen, encompassing comprehensive analyses including gamma and alpha radiation measurements, isotopic ratio determinations, and assessments of radioactive decay chain disequilibrium. Key radiological parameters such as the radium equivalent index, the external gamma absorbed dose rate and the external hazard index were calculated. The external gamma absorbed dose is equal or lower than 57 nGy h 1 (mean value worldwide in the Earth’s crust). The remaining indexes as well as the annual dose rate are far from the limits allowed for public. Fallout due to 137Cs is negligible and below the minimum detectable activity (MDA). Ratios 238U/232Th varies from 0.55 in Catamayo to 1.11 in Taquil. These values show disequilibrium between the two radioactive chains and it is possible to assume A (238U)~0.64 A (232Th) (excluding Taquil, value 1.11). Furthermore, the radiological composition of commonly used fertilizers, including urea, NPK, NH4NO3, KNO3 and compost, was analyzed, identifying 40K and 210Pb as significant radionuclides. Interestingly, no correlation was found between the types of fertilizers used and the radiological composition of soils. The predominance of the radiological background provided by the parent rock remains the main factor influencing soil composition. The radiological background values for 226Ra, 228Ra, and 40K were established, with a mean value of 23 ± 5 Bq kg 1, 30 ± 4 Bq kg 1, and 450 ± 80 Bq kg 1, respectively. Finally, the distribution of 210Pb in unperturbed soils suggests a higher concentration in the top layer, which is indicative of natural deposition patterns, except in areas affected by erosion such as Vilcabamba, Loja, and CatamayoThis research was funded by the following projects: Operative FEDER
