Bayarri-Porcar, V. et. al. Exploring the Use of Eye Tracking to Evaluate Usability Affordances: A Case Study on Assistive Device Design (Dataset)
No full textThis dataset contains eye-tracking and usability evaluation data collected for the study entitled “Exploring the Use of Eye Tracking to Evaluate Usability Affordances: A Case Study on Assistive Device Design”. The study involved 64 participants (mean age: 39.2 years; SD: 11.3) and was structured in two phases. In the first phase, participants viewed 3D-rendered images of six different jar-opening devices, each presented in two design variants—with and without rubber grip elements—while their gaze was recorded. In the second phase, participants physically interacted with the same devices in a hands-on usability task. For each device, participants rated six affordances: robustness, comfort, easiness to grip, lid slipperiness, effort level, and easiness to use.
The dataset includes eye-tracking metrics (e.g., fixation durations, fixation counts, and visit durations) from the visual inspection phase. The dataset is valuable for research in human factors, product ergonomics, and user-centered design, particularly in the context of early-stage evaluation of assistive technologies
Impact of generational diversity on organisational culture
No full textTreball Final de Grau en Psicologia. Codi: PS1048. Curs: 2024/2025The coexistence of multiple generations in today’s workplace represents one of the main challenges
and opportunities for organisations. Differences in values, expectations, communication styles, and
ways of understanding work can directly influence motivation, job satisfaction, and the
organisational climate. This study presents a systematic review of the scientific literature with the
aim of: (1) identifying whether intergenerational differences affect the functioning of organisations;
(2) understanding how each generational cohort values work and how these differences impact the
work experience; and (3) analysing the role of reverse mentoring as a strategy to foster
intergenerational collaboration. The review was conducted using the PRISMA convention, following
the guidelines of Moher et al. (2021). Structured searches were carried out in the PsycINFO and
Scopus databases, selecting empirical studies published between 2015 and 2024 that employed
structured questionnaires and robust statistical analyses.
The results reveal relevant generational differences in relation to the meaning of work, job
expectations, organisational commitment, and methods of communication and collaboration.
However, common ground was also identified across generations, as well as a tendency to
exaggerate certain differences based on stereotypes not always supported by empirical evidence.
Additionally, reverse mentoring emerges as an effective tool for reducing tensions, encouraging
mutual learning, and strengthening cohesion between generations. Under favourable organisational
conditions—such as inclusive leadership, a respectful climate, and strong organisational
identification—generational diversity can become a driver of innovation, performance, and
long-term sustainability.La convivencia de múltiples generaciones en el entorno laboral actual representa uno de los
principales retos y oportunidades para las organizaciones. Las diferencias en valores, expectativas,
estilos de comunicación y formas de entender el trabajo pueden influir directamente en la
motivación, la satisfacción laboral y el clima organizacional. Este trabajo presenta una revisión
sistemática de la literatura científica con el objetivo de: (1) identificar si las diferencias
intergeneracionales afectan al funcionamiento de las organizaciones; (2) comprender cómo cada
cohorte generacional valora el trabajo y cómo estas diferencias impactan en la experiencia laboral; y
(3) analizar el papel de la mentoría inversa como estrategia para fomentar la colaboración
intergeneracional. La revisión se ha llevado a cabo aplicando la convención PRISMA, siguiendo las
directrices de Moher et al. (2021). Se realizaron búsquedas estructuradas en las bases de datos
PsycINFO y Scopus, seleccionando estudios empíricos publicados entre 2015 y 2024 que emplearan
cuestionarios estructurados y análisis estadísticos robustos.
Los resultados muestran que existen diferencias generacionales relevantes en cuanto al significado
del trabajo, las expectativas laborales, el compromiso organizacional y las formas de comunicarse y
colaborar. Sin embargo, también se identifican puntos comunes entre generaciones y una tendencia
a sobredimensionar ciertas diferencias bajo estereotipos no siempre fundamentados.
Además, la mentoría inversa se presenta como una herramienta eficaz para reducir tensiones,
promover el aprendizaje mutuo y fortalecer la cohesión entre generaciones. Bajo condiciones
organizativas favorables—como un liderazgo inclusivo, un clima de respeto y una fuerte
identificación con la organización—la diversidad generacional puede convertirse en un motor de
innovación, rendimiento y sostenibilidad organizativa
Exploring the accessibility creative continuum on streaming platforms: A contrastive multimodal analysis of subjectivity and objectivity in audio description
No full textThe suitability of objective or subjective audio description (AD) is still an ongoing topic with opposite views. While AD guidelines used by some countries and streaming platforms support the traditional perspective of providing an objective or denotational description, growing interest has developed among researchers towards a more narrative, subjective, or interpretative description. In this paper, we explore whether the AD provided by different streaming platforms can be located at the same point along an accessibility creative continuum in terms of objectivity and subjectivity. To fulfil our aim, a multimodal analysis based on audiovisual texts’ meaning codes was used to operationalize how objectivity and subjectivity interact in a corpus of AD in English from Netflix, Amazon Prime Video, Disney+, and Apple TV+. Our results show, firstly, that both objectivity and subjectivity appear in the AD excerpts from every platform. Secondly, our findings point to dissimilarities when comparing the frequency of objective and subjective elements that interact in each platform’s AD. More specifically, whereas Apple TV+ seems to be closer to the objectivity end of the creative continuum, Disney+ can be located near the subjectivity end, with both Amazon Prime Video and Netflix being roughly in the middle. In conclusion, if we consider pure objectivity and subjectivity in AD as two opposite poles of a continuum, the AD provided by these streaming platforms displays different degrees of creativity

Unraveling the Role of Open Metal Sites and Their Capping Ligands in MOFs Stability and Liquid-Phase Separation
No full textThe stability of metal–organic frameworks (MOFs) is crucial for their practical applications. Open metal sites (OMS), essential active sites in various applications, also significantly impact stability, yet their role remains insufficiently understood. This study investigates MOF-808, a zirconium-based MOF with six OMS per cluster, revealing its higher stability in liquid water compared to gaseous water. Coordination of formic acid at OMS notably enhances water stability, while recrystallization experiments elucidate the mechanisms of instability in gaseous water. Thermal stability is determined by the decomposition temperature of capping ligands on OMS. In liquid-phase adsorption of high-value bio-oil compound creosol, uptake results demonstrate that capping ligand polarity modulates pore hydrophilicity/hydrophobicity, affecting adsorption selectivity. Remarkably, MOF-808 capped with pentafluorobenzoic acid achieves 100% selective pore occupancy during adsorption. This study highlights OMS as critical to MOF stability and emphasizes the role of capping ligands in improving stability and tuning adsorption properties. It underscores nonstructural ligand modifications as a powerful strategy to enhance MOF performance, broadening their application potential in challenging environments.This work was supported by the National Natural Science Foundation of China (22471027, 22101039, 22311530679), the State Key Laboratory of Catalysis (2024SKL-A-006, N-23-01), the Foundation of State Key Laboratory of Coal Conversion (J24-25-611), the Fundamental Research Funds for the Central Universities (DUT24LK004), the Open Research Fund of Guangdong Advanced Carbon Materials Co., Ltd.

The Map of Employment Relationships in Spain
No full textEste estudio es el primer intento de mapear un atributo empresarial clave de la Gestión de Recursos Humanos (GRH): la relación laboral. Utilizando un diseño de investigación exploratorio, se clasifican los municipios españoles según la prevalencia de empresas que siguen un determinado tipo de relación laboral y se identifica su distribución geográfica en España a través de mapas coropléticos interactivos (véase https://datawrapper.dwcdn.net/sbinS/1/). Además,
se examina cómo los tipos de relaciones laborales se asocian con diversas características demográficas (i.e., urbanización y envejecimiento). Los resultados ilustran el perfil típico de las relaciones laborales en los municipios españoles, donde predomina la relación laboral contractual. Las relaciones laborales y los factores demográficos interactúan, enfatizando el arraigo de la GRH en el contexto social y la concepción del municipio como un ecosistema de recursos humanos.This study represents the first attempt to map a critical business attribute related to human resource management (HRM): the employment relationship. Using an exploratory research design, it classifies Spanish municipalities based on the prevalence of companies adopting specific types of employment relationships and visualises their geographical distribution across Spain through interactive choropleth maps (see https://datawrapper.dwcdn.net/RLhX0/2/). Furthermore, it explores the associations between different types of employment relationships and various demographic characteristics (i.e., urbanisation and ageing). The findings reveal the typical profile of employment relationships in Spanish municipalities, where the quasi-spot contract employment relationship is predominant. The study highlights the interplay between employment relationships and demographic factors, underscoring how HRM is embedded in the societal context and framing the municipality as a human resource ecosyste

Dynamic Viscosity and Specific Heat Capacity of Near Eutectic Gallium–Indium–Tin Alloy
No full textThe study presents experimental data of the viscosity and specific heat capacity of the near eutectic gallium–indium–tin alloy. Viscosity data cover the temperature range from the alloy’s melting point of 283.85 K (10.70 °C) to about 370.47 K (97.32 °C). Two independent teams using a capillarity viscosimeter and an oscillating cup viscosimeter obtained almost identical values. Below 373 K (100 °C) the data follow the Arrhenius correlation. Specific heat capacity data result from differential scanning calorimetry measurements and reach from 236 K (− 37 °C) to 340 K (67 °C). The Neumann–Kopp rule gives neither the solid nor the liquid state a satisfactory representation of the data. Approximation functions represent these two regions separately in an excellent manner. The study discusses several issues related to the thermophysical properties, namely melting and crystallisation, and a possible liquid-to-liquid crossover
Mental health and academic performance in adolescents : elucidating the role of psychological well-being and psychological distress. DADOS Study
No full textAdolescents' mental health and academic performance are subjects of paramount interest. Previous studies have revealed a strong association between these constructs during school years. However, there is little evidence about the dual-factor model of mental health, which includes a combination of psychological well-being and distress indicators, and there is no clear consensus on the possible differences by sex. Therefore, the aims of this study were to analyze the association between the dual-factor model of mental health and academic performance and to analyze sex differences in a sample of secondary school students. The sample was formed by a total of 265 adolescents (126 females) aged 13.9 ± 0.3 years old, from the DADOS study. Mental health status was self-reported through the Behavior Assessment System for Children and Adolescents. Academic performance was assessed through academic grades and the Test of Educational Ability. The findings showed that the emotional symptoms index was negatively associated with academic grades. Psychological well-being was positively associated with academic grades, while psychological distress was negatively associated with academic grades, except for anxiety. Stratified analyses by sex showed largely similar results. These results expand the current knowledge, supporting the idea that promoting mental health during adolescence could help to enhance academic grades.Funding for open access charge: CRUE-Universitat Jaume
