Automatically Generated Subtitles and Closed Captions: ESP Students’ Perceptions of Artificial Intelligence Hallucinations
Full text linkThis article is an exploratory study which re-evaluates the use of automatically generated subtitles and closed captions inside and outside the classroom with the help of questionnaire responses from twenty-eight students of Chemical and Process Engineering who were learning English for Specific Purposes (ESP) as part of their compulsory classes. By focusing on AI errors in closed captions and subtitles this research explores an area that is presently absent from the literature. This article gives an insight into how students perceive the AI errors or hallucinations they encounter and establishes three learner profiles based on their answers. The findings show a large degree of autonomy in students’ use of captions and subtitles while at the same time giving insight into their beliefs about generative AI
A Systematic Review of Generative Artificial Intelligence-based Tools to Improve Oral Skills in English as a Foreign Language
Full text linkThe emergence of artificial intelligence (AI) and chatbots has completely revolutionised language teaching practices. The power AI holds in EFL language instruction is evident: supporting students through material creation, providing continuous feedback, and facilitating tailored learning pathways, offering greater autonomy, creativity, and confidence. Through scaffolding, student-centred strategies, and inquiry-based approaches, AI facilitates and ensures an inclusive, adapted educational experience for all students, regardless of their levels, needs, or interests (Dennis, 2024; Lee et al., 2024; Mai & Carson-Berndsen, 2024; Sayed et al., 2024).
Chatbots play a vital and multifaceted role in the development of EFL oral skills, enabling tailored and targeted instruction in pronunciation, vocabulary, grammar, and other communicative aspects essential for successfully navigating real-life communicative situations (Fathi et al., 2024; Tai & Chen; 2024). They provide instant feedback, continuous accessibility and personalised learning strategies, contributing not only to enhanced language accuracy but also to fostering learners' confidence, motivation, and autonomy in communicative situations, helping students address and overcome specific linguistic challenges (Zou et al., 2024). Nonetheless, despite their potential, AI tools also present various challenges and complexities that must be considered to ensure their effective use, such as a lack of context, coherence, or meaningful interaction (Shikun et al., 2024). Thus, this paper presents a systematic review of 14 relevant studies from the Web of Science (WOS) and Scopus databases, focusing on AI and EFL oral skills. It examines the impact of AI chatbots on the oral skill acquisition process, identifying key areas for further exploration. Consequently, the following study aims to contribute to current research in the field by exploring the multiple possibilities of these advanced tools, enhancing ELT practices and providing learners with a more holistic and higher-quality education
Current relevance of the historic construction technique of Bousillage using Spanish moss, golden broom, and Posidonia oceanica
Full text linkBousillage is a traditional construction technique used to build vertical and horizontal enclosures in tropical, West European, and Mediterranean regions. It uses a timbered structure called colombage and a fibrous filler made from natural waste. This research paper confirms the current practice of this ancient technique by analyzing its structural, hydrothermal and environmental peculiarities through the examination of three persistent solutions that use golden broom, Spanish moss, and Posidonia oceanica as binders. The methodology begins with a theoretical framework that confirms the technique’s historical roots according to context. Then, field and hygrothermal data is collected for each vegetal binder type. The main objective is to test the initial hypothesis that bousillage is a symbiotic construction method which creates a balance between nature and anthropocentrism in the local ecosystem—regardless of the plant waste used or the climatic context in which it is developed. The research results clarify that this environmental balance is achieved when waste discarded by nature is used as an active component in thermal building improvements. This benefits both the fauna and flora species, as well as anthropized neighborhoods. In conclusion, reviving this traditional technique in accordance with the current ecological situation, creates necessary anthroponatural interdependence for the long-term survival of the ecosystem

Visibilidad y organización espacial en las necrópolis de cuevas artificiales prehistóricas de Menorca
Full text linkThis paper presents an intervisibility study applied to a set of necropolises on the island of Menorca. 25funerary complexes have been analysed, each comprising a variable number of funerary units. These complexes include caves from different prehistoric periods, ranging from the Late Bronze Age to the Second Iron Age and the Roman period. Among them, both natural caves and the so-called artificial caves (rock-cut tombs) are documented. These artificial caves exhibit notable morphological variability, either for chronological reasons or due to their inherent structural differences. The intervisibility analyses aim to identify mesospatial patterns in the arrangement of caves within each complex, to determine which ones exert greater visual control over the rest and which are more exposed. The results have been cross-checked against previous studies of cumulative visibility and related to the typology of the tombs, examining them from a morpho-architectural perspective. It should be noted that some of the caves that are structurally more complex show a significantly greater investment of labour in their external elements, in some cases, through moulded bands framing the entrances; in other cases, one can observe the excavation of open courtyards in the rock at the funerary chambers entrance. For the analyses, the research team used the Visibility Analysis plugin available in QGIS, a free and open-source software under the GNU GPL license. First, a 1-m-resolution digital terrain model (DTM)was generated from light detection and ranging (LiDAR) point clouds available as open data from the Spanish National Geographic Institute (IGN). Subsequently, intervisibility calculations were run for each funerary complex and the data were compared with the cumulative visibility results obtained in previous work. Raster-based calculations were used to identify the funerary units that exercised greater visual control over the rest and those that, applying spatial statistics, commanded a larger portion of the surrounding territory. To sum up, this set of analyses makes it possible to recognize the caves that play a predominant role within the funerary complexes under study, as well as to formulate hypotheses, both about their spatial articulation and about its possible reflection in the social order of the prehistoric communities that inhabited Menorca during the first millennium BCE.En este trabajo se presenta un estudio de intervisibilidad aplicado a un conjunto de necrópolis de la isla de Menorca. Se han analizado 25 conjuntos funerarios, cada uno de ellos integrado por un número variable de unidades funerarias. Estos conjuntos incluyen cuevas pertenecientes a distintos momentos prehistóricos, que abarcan desde el Bronce Final hasta la Segunda Edad del Hierro y la época romana. Entre ellas se documentan tanto cuevas naturales como las denominadas cuevas artificiales. Estas últimas presentan una notable variabilidad morfológica, ya sea por razones cronológicas o por diferencias estructurales propias. Los análisis de intervisibilidad realizados tienen como objetivo tanto identificar los patrones meso-espaciales en la disposición de las cuevas dentro de cada conjunto, como determinar cuáles presentan un mayor control visual sobre el resto y cuáles se hallan más expuestas. Los resultados se han contrastado con estudios previos de visibilidad acumulada y se han puesto en relación con la tipología de las tumbas, examinándolas desde una perspectiva morfo-arquitectónica. Cabe señalar que algunas de las cuevas más complejas desde el punto de vista estructural evidencian una inversión de trabajo significativamente mayor en sus elementos externos, en algunos casos, mediante bandas molduradas que enmarcan los accesos; en otros casos, se observa la excavación de patios abiertos en la roca a la entrada de las cámaras funerarias. Para la realización de los análisis se empleó el complemento Visibility Analysis disponible en QGIS, un software libre con licencia GNU GPL. En primer lugar, se generó un modelo digital del terreno (MDT) con resolución de 1 m, a partir de las nubes de puntos LiDAR (‘Light Detection and Ranging’) disponibles en acceso abierto en el Centro de Descargas del Instituto Geográfico Nacional. Posteriormente, se ejecutaron los cálculos de intervisibilidad para cada uno de los conjuntos funerarios y se cruzaron los datos con los resultados de visibilidad acumulada obtenidos en trabajos anteriores. Mediante cálculos efectuados sobre los datos ráster, se identificaron aquellas unidades funerarias que ejercían un mayor control visual sobre el resto y aquellas que, aplicando estadísticas espaciales, dominaban una mayor porción del territorio circundante. En definitiva, este conjunto de análisis permite reconocer las cuevas que desempeñan un papel predominante dentro de los conjuntos funerarios estudiados y formular hipótesis sobre la articulación espacial de los mismos, así como sobre su posible traducción en el orden social de las comunidades prehistóricas que habitaron Menorca durante el I milenio a.n.e
El diagrama en la ideación arquitectónica de Eisenman, Tschumi, OMA y SANAA
Full text linkThe social and cultural transformations we are experiencing have given impetus to new ideas in architectural production and systems of representation. Within these systems, the diagram has become an essential tool for architectural design in some of the most influential studios. This is the case with OMA, SANAA, Tschumi and Eisenman. The aim of this article is to study the use of the diagram by these studios as it has become an essential means of conceptualising and representing their architecture. In the case of OMA, we observe how the diagram serves to develop the programmes that characterise many of their architectural projects; at SANAA, there is a relationship between diagram and spatial resolution, their architecture having been interpreted as diagrammatic; and in the cases of Tschumi (The Manhattan Transcripts; Notations. Diagrams & Sequences) and Eisenman (Diagram Diaries; Feints) is conceived as the theoretical basis and formal development of their architecture. On the other hand, the comparison of the diagrams selected as a methodology not only shows a relationship between them, but also establishes a series of categories for rethinking this system of representation and graphic strategy within the context of contemporary architecture.Las transformaciones sociales y culturales que estamos viviendo han impulsado nuevas ideas en la producción de la arquitectura y en sus sistemas de representación. Dentro de estos sistemas, el diagrama se ha convertido en herramienta esencial para la concepción arquitectónica de algunos de los estudios más influyentes. Es el caso de OMA, SANAA, Tschumi y Eisenman. El objetivo del artículo es estudiar el uso del diagrama por parte de estos estudios al cristalizarse como un medio esencial en la ideación y la representación de su arquitectura. En el caso de OMA, observamos cómo el diagrama sirve para la elaboración de los programas que caracterizan muchas de sus arquitecturas; en SANAA se produce una relación entre el diagrama y la resolución espacial, habiéndose interpretado su arquitectura como diagramática; o en los casos de Tschumi (The Manhattan Transcripts; Notations. Diagrams & Sequences) y Eisenman (Diagram Diaries; Feints) se concibe como base teórica y desarrollo formal de su arquitectura. Por otro lado, la comparación de los diagramas seleccionados como metodología, además de mostrar una relación entre ellos, también establece una serie de categorías para repensar este sistema de representación y estrategia gráfica en el marco de la arquitectura contemporánea
Foldcast. Optimización de estructuras de hormigón con encofrado de papel
No full textConcrete is the most widely used building material worldwide, valued for its availability, strength, durability, and versatility. However, its extensive use makes it one of the largest contributors to CO₂ emissions in the built environment, despite having lower embodied carbon per unit volume than many alternatives. A transition toward more sustainable construction therefore requires reducing material consumption and minimizing waste. Foldcast addresses this challenge by enabling up to 50% material savings in structural elements through the use of low-cost, recyclable paper formwork. This method combines structural optimization strategies with digital fabrication technologies to produce large-scale concrete elements. Two full-scale applications for a ribbed concrete slab and a precast staircase demonstrate the potential of this approach to significantly reduce the carbon footprint of concrete structures while enhancing architectural design flexibility. Furthermore, the affordability and compatibility of paper formwork with conventional construction practices highlights its promise for widespread adoption in the building industry.El hormigón es el material de construcción más utilizado en todo el mundo, valorado por su disponibilidad, resistencia, durabilidad y versatilidad. Sin embargo, su uso extensivo lo convierte en uno de los mayores emisores de CO₂ en el entorno construido, a pesar de tener menos carbono incorporado por unidad de volumen que muchas alternativas. Por lo tanto, una transición hacia una construcción más sostenible requiere reducir el consumo de materiales y minimizar los residuos. Foldcast aborda este desafío permitiendo un ahorro de hasta un 50% de material en elementos estructurales mediante el uso de encofrados de papel reciclable y de bajo coste. Este método combina estrategias de optimización estructural con tecnologías de fabricación digital para producir elementos de hormigón a gran escala. Dos aplicaciones a escala real para una losa de hormigón nervada y una escalera prefabricada demuestran el potencial de este enfoque para reducir significativamente la huella de carbono de las estructuras de hormigón, a la vez que mejora la flexibilidad del diseño arquitectónico. Además, la asequibilidad y la compatibilidad del encofrado de papel con las prácticas de construcción convencionales demuestran su potencial para una adopción generalizada en la industria de la construcción

Levantamiento y análisis arquitectónico de la capilla y antiguo colegio "Sta. Mª de Jesús" (Sevilla). Estudio de su proceso evolutivo
Full text linkThe College of “Santa María de Jesús” is an early 16th-century building located at the Puerta de Jerez, one of the main entrances to the city of Seville. The building is recognized as the founding headquarters of the University of Seville and, over the centuries, underwent a complex and eventful construction process that culminated in its partial demolition during the city’s urban transformations in the late 19th and early 20th centuries. Of that original complex, only the chapel remains, recognizable to the public as an example of Gothic-Mudéjar architecture but generally perceived as an isolated element. This work aims to highlight the value of this sacred space through a comprehensive study of the building of which it was a part. To this end, a HBIM model is generated to synthesize the construction evolution of the college and its urban surroundings, as the first step in a strategy for managing the existing documentation and knowledge about it.El Colegio de “Santa María de Jesús” es una construcción de principios del siglo XVI situada en la Puerta de Jerez, uno de los accesos a la ciudad de Sevilla. El edificio se reconoce como sede fundacional de la Universidad de Sevilla y a lo largo de los siglos ha experimentado una azarosa evolución constructiva que alcanzó hasta su demolición parcial con las transformaciones urbanísticas de la ciudad a finales del XIX y principios del XX. De aquel conjunto pervive en la actualidad la capilla, reconocible por la ciudadanía como espacio exponente del gótico-mudéjar, pero entendida generalmente como un elemento aislado. Este trabajo trata de poner en valor en valor este espacio sacro a través del estudio global del edificio del que formaba parte. Para ello se recurre a la generación de un modelo HBIM que sintetiza la evolución constructiva del colegio y su entorno urbano, como primer paso de una estrategia destinada a la gestión de la documentación y del conocimiento existente sobre el mismo
La revolución de las formas barrocas en zonas sísmicas
Full text linkThe design of masonry in seismic zones requires the use of construction elements, conceived as hidden passive devices, to reduce damage caused by earthquakes. It was the fundamental need for these hidden structures that led to a clear division between "appearance" and "structure" in building design, forcing designers to push their technical knowledge to the limit. These advances in building construction are the central theme of this article. In particular, the use of these elements in the design of Baroque forms in seismic zones between the 18th and 20th centuries will be analyzed, elements that were concealed by stuccos and cladding. The case of the use of "disconnected buttresses" built against the main façades of churches, which lead to the concave façades typical of Baroque architecture, will be presented, along with the use of "blind arch" lunettes to counteract and redistribute horizontal actions. Some illustrative case studies from Mexico and Italy will be presented. To explain the use of "blind arch" lunettes and "disconnected buttresses" in the design, reference will be made to the fundamental treatises by Borgnis and Rondelet from the first half of the 19th century.El proyecto de edificios de fábrica en zonas sísmicas requiere el empleo elementos constructivos, concebidos como dispositivos pasivos ocultos, para reducir los daños producidos por terremotos. Fue la necesidad básica de estas estructuras ocultas la que provocó una clara división entre «apariencia» y «estructura» en el proyecto de los edificios, y obligó a los proyectistas a llevar al límite sus conocimientos técnicos. Estos avances en la construcción de edificios son el tema central de este artículo. En particular, se analizará el uso de estos elementos en el proyecto de formas barrocas en zonas sísmicas entre los siglos XVIII y XX, elementos que quedaban ocultos por estucos y revestimientos. Se expondrá el caso del uso de “contrafuertes desconectados” construidos contra las fachadas principales de las iglesias, que conducen a las fachadas cóncavas típicas de la arquitectura barroca, junto con el uso de lunetos de “arcos ciegos” para contrarrestar y redistribuir las acciones horizontales. Se presentarán algunos casos prácticos ilustrativos de México e Italia. Para explicar el uso de los lunetos de «arcos ciegos» y «contrafuertes desconectados» en el proyecto se hará tomando como referencia los tratados fundamentales de Borgnis y Rondelet de la primera mitad del siglo XIX
