Abstract
PurposeWithin the sports industry, fan tokens have appeared as an instrument for fostering fan engagement and empowering them to participate in club-related decision-making processes via voting mechanisms (e.g. voting rights in decisions like the design of the equipment or the bus, and the ability to win rewards such as VIP experiences with the players).Design/methodology/approachDrawing on the technology acceptance model and consumer behaviour theories, a conceptual model was established to analyse the relationship of perceived ease of use, usefulness, and financial value, brand love, brand engagement, trust, social influence and its influence on the intention to purchase fan tokens. This study also analyses the generation of positive electronic word-of-mouth (e-WOM) derived from the intention to purchase fan tokens. To achieve the proposed objective, a quantitative study was conducted, collecting data through an online survey from football fans with an interest in fan tokens. The conceptual model was analysed using partial least squares (PLS) structural equation modelling (SEM).FindingsResults show that the financial perceived value was the dimension that most contributed to explaining the purchase intention. It was also found that perceived ease of use, trust in fan tokens and brand engagement positively influence the intention to buy fan tokens. Furthermore, findings demonstrate that purchase intention positively drives e-WOM, highlighting that fans' behavioural intentions extend beyond adoption to active digital advocacy.Originality/valueResults offer effective insights for both researchers and sports practitioners, while also presenting an original conceptual model applicable to diverse sports contexts and crypto assets-related research.

Abstract
Contemporary transformations in the world of work, together with the growing emotional and physical demands in nursing, have led to the emergence of new labor phenomena such as quiet quitting, which reflects changes in professional engagement and in the management of nurses' well-being. Objective: To translate, culturally adapt, and validate the Quiet Quitting Scale for European Portuguese, evaluating its psychometric properties among the nursing population. Methods: A cross-sectional validation study was conducted following COSMIN guidelines. The process included forward and back translation, expert panel review, and pretesting with 30 nurses. The psychometric evaluation was carried out with 347 nurses from Northern Portugal. Data were analyzed using descriptive and inferential statistics, internal consistency measures (Cronbach's alpha and McDonald's omega), and confirmatory factor analysis (CFA) with maximum likelihood estimation to assess construct validity. Results: The Portuguese version (QQS-PT) maintained the original three-factor structure (Detachment/Disinterest, Lack of Initiative, and Lack of Motivation). The model showed satisfactory fit indices (CFI = 0.936; GFI = 0.901; AGFI = 0.814; TLI = 0.905; RMSEA = 0.133). The overall internal consistency was excellent (alpha = 0.918; omega = 0.922), with subscale alpha ranging from 0.788 to 0.924. Composite reliability (CR) ranged from 0.815 to 0.924, and average variance extracted (AVE) from 0.606 to 0.859, confirming convergent and discriminant validity. Conclusions: The QQS-PT demonstrated a stable factorial structure, strong reliability, and solid validity evidence. It is a brief and psychometrically sound instrument for assessing quiet quitting among nurses, providing valuable insights for research and management of professional engagement and well-being in healthcare contexts.

Abstract
A flexible wearable sensor utilizing a balloon-shaped interferometer structure, created from a bent standard single-mode fiber and a 3D-printed piece, was introduced and shown for respiratory monitoring. The interferometer is a compact, cost-effective, and easily fabricated sensor. The fiber's curvature causes interference between the core and cladding modes, which in turn results in the sensor operation. In the balloon-shaped curving section, light traversing the core partially escapes and interacts with the cladding. The preliminary results demonstrate an average displacement of 9.3 nm and the capability to evaluate breathing rate.

Abstract
People around the globe struggle with health issues requiring regular medication. Children, in particular, suffer more and more from chronic illnesses. In 2024, a team of six EPS@ISEP students chose to design a solution for this problem, followed by the assembly and testing of the corresponding proof-of-concept prototype. The aim was to design a solution for children to take the right medication, at the right time and in the right dose, in a pleasant and engaging way, based on technical, ethical, sustainability and market analyses. Focusing on children between the ages of 8 and 12, the team decided to incorporate a motivational system based on rewards to ensure that they take their medication correctly. The outcome is billy, a pill dispenser controlled via an app which allows carers to plan doses and release rewards, and children to autonomously take their medication. The system dispenses up to 21 doses of medication to the child through fingerprint authentication, and photographs the child taking the medication to reassure carers.
