Memoria final del proyecto Prados-Castillo, Juan Francisco; Gálvez-Sánchez, Francisco Jesús; Liébana Cabanillas, Francisco José; Lara Rubio, Juan; Martínez Torres, Virginia El proyecto se ha diseñado con el propósito de analizar los factores que condicionan la adopción de la tecnología blockchain desde una perspectiva multidimensional. En particular, se ha abordado la brecha existente entre el elevado potencial tecnológico de esta tecnología y su adopción efectiva por parte de consumidores, organizaciones y administraciones públicas. La literatura científica ha señalado que blockchain ofrece beneficios relevantes asociados a la trazabilidad de las transacciones, la transparencia de los sistemas de información, la automatización mediante contratos inteligentes y la reducción de intermediarios. No obstante, también se han identificado diversos factores que han limitado su expansión, entre los que se han destacado la complejidad percibida, la falta de confianza en las plataformas, la incertidumbre regulatoria, los costes de implementación y las dudas sobre la sostenibilidad económica de determinados modelos de negocio. Con el fin de abordar estas cuestiones, el proyecto ha adoptado un enfoque analítico que ha integrado tres dimensiones complementarias. En primer lugar, se ha analizado la dimensión psicológico-conductual vinculada a las percepciones y actitudes de los usuarios hacia la tecnología. En segundo lugar, se ha examinado la dimensión sectorial y estratégica relacionada con la aplicación de blockchain en sectores económicos concretos. Finalmente, se ha considerado la dimensión económico-regulatoria, centrada en la identificación de barreras institucionales y fiscales que condicionan la implementación de esta tecnología. A pesar de tratarse de un proyecto precompetitivo con un presupuesto final reducido, la investigación se ha orientado a maximizar el retorno científico mediante una estrategia basada en una revisión rigurosa de la literatura, el desarrollo de contrastes empíricos y la generación de resultados susceptibles de publicación en revistas científicas internacionales.

In this context, communication-based regulations that aim to reduce car dependency can support both environmental and health goals. This study evaluates the introduction of mandatory health and environmental warnings in car advertising as an emerging policy instrument to promote sustainable and healthy mobility, drawing on evidence from Granada (southern Spain). Methods A qualitative design was employed, using focus group discussions with 37 adults private car users segmented by age and level of environmental concern. The study explored participants’ awareness of car-use warnings, their perceptions of message credibility, and the behavioural and cognitive responses these warnings elicited. Results Findings indicate that many participants overlooked or dismissed the warnings as symbolic, particularly when the messages were small, poorly integrated, or perceived as inconsistent with broader transport and health policies. Nevertheless, the warnings prompted moral reflection and cognitive engagement among younger and more environmentally concerned participants, suggesting their potential contribution to gradual cultural change in mobility attitudes. Conclusions Policy coherence, visibility, and credibility are critical conditions for the success of communication-based interventions. When integrated into broader strategies that promote active and sustainable travel, warning labels can complement public health efforts to reduce emissions, sedentary lifestyles, and traffic injuries. The study offers practical insights for policymakers seeking to design credible, health-aligned information tools that foster behavioural change toward healthier and more sustainable mobility. https://hdl.handle.net/10481/111937 https://hdl.handle.net/10481/111877 Unlocking the future of paytech: exploring biometric payment card adoption patterns Liébana Cabanillas, Francisco José; Irimia-Diéguez, Ana; Albort Morant, Gema; Zarco, Carmen With the transition to a cashless society and the evolving regulatory framework gov erning electronic payments, the advent of novel payment systems has become increas ingly apparent. In this context, biometric payment cards have emerged as a promising alternative to enhance security, convenience, and efficiency in electronic transactions. An online questionnaire was administered to a sample of users experienced in mobile payment systems, and structural equation modeling was utilized to identify the vari ables significantly affecting usage and recommendation. The results confirm the pro posed hypotheses, except for those related to social influence and perceived risk. This study provides a unique contribution by investigating the factors influencing the adop tion and word‑of‑mouth (WOM) of biometric payment cards, integrating elements from the unified theory of acceptance and use of technology 2 (UTAUT2), general risk theory, and trust theory. This research is highly relevant for financial institutions, tech companies, marketers and policymakers, as it informs user strategy development for businesses operating within the biometric payment sector and suggests guidelines for enhancing consumer trust and reducing perceived risks associated with biometric payments. https://hdl.handle.net/10481/111877 https://hdl.handle.net/10481/111603 Eyes on the Prize: Eye-Tracking Evidence of Attentional Biases Toward Gambling and Natural Rewards Sánchez-Fernández, Francisco-Luis; Viedma Del Jesús, María Isabel; Ibáñez Zapata, José Ángel; Sánchez Fernández, Juan; Montoro Ríos, Francisco Javier The present study investigates attentional biases (ABs) in gamblers and non-gamblers, focusing on both gambling-related and food-related stimuli to examine the relationship between these biases and the Incentive Sensitization (IS) and Reward Deficiency Syndrome (RDS) models of addiction. Using an eye-tracking methodology, we assess how ABs differ across three conditions involving two types of images: Food vs. Gambling, Food vs. Neutral, and Gambling vs. Neutral. Gamblers showed a significant AB toward gambling-related stimuli compared to neutral cues, supporting the IS model. However, when gambling and food images were compared, no significant difference in AB was found, partially disconfirming the hypothesis that gamblers exhibit a stronger bias toward gambling stimuli. In contrast, non-gamblers demonstrated a clear preference for food-related images, as predicted by the IS model. Additionally, group differences revealed that gamblers allocated more attention to gambling-related cues than non-gamblers. However, food images elicited similar levels of attention from both gamblers and non-gamblers when compared to neutral images, rather than gambling-related images. These findings highlight the role of ABs in the development and maintenance of gambling behaviour, supporting the IS model but not the RDS model. The study also explores the association between AB and severity of gambling and other relevant psychological factors in gambling disorder, providing new insights into the cognitive mechanisms underlying gambling addiction. These results suggest that ABs could be targeted in interventions aimed at modifying attention patterns and reducing gambling-related cravings.
