Luchas de poder, conflictos en el espacio público y desigualdades de género entre escritores de graffiti
No full text264 p.La investigación buscar explicar de forma exhaustiva todos los procesos sociales que influyen en las trayectorias de los y las escritoras de graffiti. Desde el comienzo de su actividad, el proceso de construcción identitaria como grupo social hasta el abandono de la misma. Para responder a estos interrogantes se llevaron a cabo 49 entrevistas en profundidad y 16 observaciones de escenas de graffiti, en Granada y Bilbao.La principal tesis que sostiene el conjunto de interpretaciones sobre el comportamiento del colectivo es que los y las escritoras de graffiti se comportan como jugadores de un campo social, como lo definió P. Bourdieu. Dentro de este campo social se ponen en juego dinámicas de discriminación hacía las mujeres y diferentes luchas simbólicas por imponer una determinada definición de graffiti. En base a esta premisa también se explican los diferentes niveles de implicación política del colectivo, en función de la posición relativa que ocupe cada persona en el campo del graffiti.Por último, se analiza la influencia de la facultad de Bellas Artes o las ordenanzas municipales en las dinámicas internas del colectivo. En este sentido, se concluye que las ordenanzas muy restrictivas empujan a estas personas a la realización de un graffiti rápido y menos elaborado. Respecto a las facultades, aunque no influyen en la construcción de significados, sí operan como espacios que posibilitan la ampliación de capital social entre jugadores del camp
An open-source reference framework for the implementation of type 3 Asset Administration Shells
No full textSeamlessly integrating assets into distributed digital ecosystems based on Industry 4.0/5.0 demands measurable impact: lower engineering cost, interoperability and adaptability. SMIA (Self-configurable Manufacturing Industrial Agents) addresses this as an reference framework for implementing autonomous digital counterparts of assets, unifying industrial and software standards. Its dual-layer architecture combines machine-interpretable semantic modeling with distributed functional software, enhancing interoperability, flexibility, and autonomy. SMIA represents assets by executing domain-specific tasks and performing peer-to-peer communication through standardized interfaces. Following open scientific software principles, it integrates mature technologies and provides reproducible deployment artifacts (e.g., Docker), ensuring traceability and extensibility while reducing engineering effort and technological fragmentation.University of the Basque Country (EHU) [grant number PIF23/223]

The effect of a hybrid educational escape room on undergraduate nursing students’ nursing process knowledge
No full textThis study examined differences in declarative knowledge acquisition between a hybrid educational escape room and traditional lecture-based learning (LBL), and explored students’ experiences with the gamified intervention.
A quasi-experimental pre-test/post-test design was conducted with 152 second-year nursing students. The experimental group completed a hybrid escape room combining on-site and digital tasks, while the control group received LBL. Declarative knowledge was assessed in both groups, and game-related experiences were measured in the experimental group.
Students in the experimental group showed significantly greater improvements in learning outcomes compared to those in the control group. Participants also reported positive experiences, including enjoyment, activation, creative thinking, autonomy and absorption.
Hybrid educational escape rooms can enhance learning outcomes while fostering positive learning experiences. Implications for international audience: Hybrid escape rooms may be effective across diverse educational systems, suggesting that knowledge gains can occur independently of changes in motivation or subjective enjoyment
La automarginación del Consejo de Seguridad en la lucha armada contra el terrorismo internacional
No full textAunque los Estados que han emprendido acciones armadas contra grupos terroristas se han amparado fundamentalmente en el supuesto derecho a la legítima defensa contra actores no estatales o la intervención por invitación, el Consejo de Seguridad de Naciones Unidas también ha autorizado el uso de la fuerza contra el terrorismo internacional en algunos casos. En este artículo, a través del estudio de las diferentes resoluciones que autorizan el uso de la fuerza en este supuesto, se determina la actitud del Consejo de Seguridad en lo que respecta a la lucha militar antiterrorista. Así, se concluye que el órgano decidió automarginarse en este aspecto. Esta actitud tiene efectos muy nocivos para el órgano, la lucha antiterrorista y el conjunto del derecho internacional
Partial privatization and the degree of corporate social responsibility of private investors
No full textA significant issue for study is what type of private investor governments should sell public firms to: those who care about corporate social responsibility (CSR) or those who are profit-maximizers. To analyze this issue we measure CSR concern through consumer surplus and consider a market in which a private and a public firm compete. We find that the decision taken by the government crucially depends on the social concern of the rival private firm. When that firm cares about CSR, selling part of the public firm to socially concerned private investors is no worse than selling to profit-maximizing investors. However, when the private firm maximizes profits the opposite result is obtained. In addition, from a social welfare viewpoint, when social concern is not high it is desirable for all private investors to engage in CSR. Otherwise, it is preferable for them not to care about society.This work was supported by the Ministerio de Ciencia, Innovación y Universidades (grant number PID2019-105291 GB-I00 MCIN/AEI/10.13039/501100011033); the Basque Government (grant number IT1461-22); and Grupos UPV/EHU (grant number GIU23/013)
Imagen texto y peritexto: elementos característicos en 11 libros álbum destinados al fomento de la lectura en estudiantes de 9 a 13 años
No full text326 p.El presente estudio doctoral considera la relevancia del libro álbum para el fomento de la lectura. Su objetivo general es examinar la presencia e interacción de texto, imagen y peritexto como elementos característicos en 11 libros álbum recomendados para el fomento de la lectura literaria en lectores de 9 a 13 años. Su marco teórico se fundamenta en los elementos peritextuales del soporte que aportan contenido al lector, el lenguaje textual que se manifiestan en toda narración, en los elementos de la imagen como parte de la narración y en la relación entre texto e imagen. El diseño metodológico se remite a la aplicación del paradigma cualitativo apoyado en la técnica de una investigación documental cuyo análisis de contenido se desarrolló en dos niveles. El primero es un análisis descriptivo de 11 libros álbum recomendados para el fomento de la lectura literaria en lectores de 9 a 13 años y el segundo es un análisis interpretativo de tres elementos característicos del libro álbum: soporte como espacio peritextual, texto como elemento en la construcción narrativa y la imagen como elemento narrativo. Como conclusión general se resalta la riqueza del libro álbum como una nueva forma de producir lectura literaria no tradicional para lectores entre 9 y 13 años. Se subraya la importancia de los elementos estudiados, dado que aportan a la lectura en pro de una apropiación en la comprensión y de un papel activo del lector

Environmental taxes when firms care about environmental corporate social responsibility
No full textThis paper studies the incentive by governments to implement emissions taxes when firms are environmentally friendly. We find that the decision of governments on whether to establish a tax or not depends on three factors: the degree of environmental concern of the firms, the R&D knowledge disclosed by them and whether governments cooperate in setting taxes. When countries do not cooperate and firms do not share their knowledge both countries set emissions taxes for low levels of the concern, while either firm sets taxes if the concern is sufficiently high. If countries cooperate, they want to implement taxes for higher values of the concern. Under full information disclosure, when countries do not cooperate an asymmetric equilibrium arises: only one country implements a tax for intermediate values of the concern. However, when countries cooperate they levy taxes for all the values of concern. Thus, cooperation encourages governments to implement environmental policies
Everyday nationalism in individualised political practices. Young left-wing Basque nationalists experiencing the nation in changing times
No full textThis article is based on a qualitative case study focusing on the ways in which young leftwing
nationalists in the Basque Country experience the nation in different areas of their
lives, outside of political organisations. The analysis shows, on the one hand, the
emergence of individualisation processes of youth practices in the current project of
reconstruction and reformulation of left-wing Basque nationalism and the incorporation
of these practices into everyday life. On the other hand, it confirms the diversification of
meanings attributed to the nation, which runs parallel to the inclusion of global political
agendas of the contemporary social movements in this current of nationalism, and the
plurality of interests and positions which the different young nationalists use to assert their
agency
Temperature and vector bending sensing with a supermode fiber Bragg grating
No full textDue to their multiple advantages, single-mode fiber Bragg gratings (FBGs) are widely used in a myriad of practical sensing applications. However, their concurrent sensitivity to strain and temperature makes a reference sensor necessary in several situations. Here, we demonstrate that a single supermode FBG can be used to measure bending and temperature. A specially designed two coupled-core optical fiber (TCCF) that supports two supermodes was fabricated in which gratings were inscribed with femtosecond or ultraviolet lasers. The interrogation of the gratings was carried out with a conventional FBG sensor interrogator. It was found that the reflection spectrum of the supermode grating depended on its inscription in the TCCF. So, it was possible to fabricate samples in which the reflection spectra exhibited two narrow peaks very close to each other with well-defined Bragg wavelengths and reflectivities. Cross sensitivities and polarization effects on the devices were studied. It was found that two Bragg wavelengths and two reflectivities provided abundant data to measure bending of the TCCF, temperature, and to discriminate in which direction the TCCF was bent. Thus, we believe that the results reported here can pave the way for next-generation grating-based specialty optical fiber devices that are capable of multiparameter sensing. The results and approaches proposed here can also expand the use of Bragg grating technology.This work was funded in part through Projects PDC2022-133885-I00; PID2023-152763NB-I00; INNOFIBER PID2023-152314OB-I00, and SMARTMOORING Cetp-2022-00382, PCI2023-145987-2 funded by the Spanish MCIU/AEI /10.13039/501100011033 and the European Union Next Generation EU/PRTR, IT11452-22 funded by the Basque Government and P2022-06 funded by the EU Horizon2020 Actphast4R GA 825051.
