However, the construct remains conceptually fragmented, with existing measures often limited to affect or job satisfaction. This study addresses these limitations by proposing and preliminarily validating a multidimensional instrument that integrates hedonic and eudaimonic dimensions of workplace happiness: emotional well-being and purpose, work–life balance, and work relationships and support. Using a multi-phase research design, including expert content validation, a pilot study (n = 100), and large-scale psychometric testing (n = 354), the study applies exploratory and confirmatory factor analyses. Results provide initial evidence of strong structural validity, internal consistency, and convergent and discriminant validity (CFI = 0.971; TLI = 0.959; RMSEA = 0.078). Workplace happiness is conceptualised as a synergy of affective fulfilment, meaningful contribution, and supportive relationships. Despite cross-sectional and non-probabilistic limitations, the instrument offers a robust foundation for future validation and human-centred organisational research Mon, 01 Dec 2025 00:00:00 GMT https://repositorio.cetys.mx/handle/60000/2003 2025-12-01T00:00:00Z https://repositorio.cetys.mx/handle/60000/2000 Title: Effects of happiness management and organisational justice on organisational commitment Authors: Galván Vela, Esthela; Martínez Arvizu, Orlando Josúe; Salazar-Altamirano, Mario Alberto; Ravina-Ripoll, Rafael Abstract: Purpose – The results confirm that Human Resource Practices (HRPs) positively influence both happiness management and brand pride, but not performance directly. In contrast, both happiness management and brand pride significantly affect job performance. Furthermore, a marginal mediation of happiness management is also observed in the relationship between HRPs and performance (p 5 0.051), which suggests a near-significant emotional mechanism. Significant mediations of brand pride and happiness management are also found between pride and performance. Design/methodology/approach – A quantitative cross-sectional design was employed with 408 participants. Data were analysed using covariance-based structural equation modelling (CB-SEM) to assess the direct and indirect relationships proposed in the theoretical model. Findings – The results reveal that happiness management is positively associated with both organisational justice and commitment, with justice partially mediating this relationship. Research limitations/implications – The cross-sectional design and non-probabilistic sampling restrict causal inference and generalisability. Future studies should employ longitudinal approaches and test moderators such as leadership style or perceived organisational support. Practical implications – The findings guide higher education leaders to implement emotional and psychological training programmes that foster happiness, fairness and commitment through transparent workload allocation, fair promotion systems and participatory decision-making. Social implications – Promoting organisational cultures grounded in happiness and justice strengthens equity, well-being and institutional resilience, contributing to the Sustainable Development Goals SDG 4 (Quality Education) and SDG 8 (Decent Work and Economic Growth). Originality/value – The study provides novel evidence in the Ibero-American context by integrating four constructs into a single explanatory model, extending social exchange theory from an emotional perspective. It highlights that happiness management constitutes a management strategy and an ethical and cultural responsibility for building more human and sustainable organisations. Practical implications include promoting emotionally intelligent communication,symbolic recognition practices and a culture thatfosters employee pride and well-being.

Desktop implementations of deep learning achieved state-of-the-art performance on TSC benchmarks; however, they are unsuitable for real-time embedded systems due to resource limitations. We propose an Efficient GPU-Embedded Network (EGENet) for embedded platforms, such as NVIDIA’s Jetson, to overcome these drawbacks. When implemented on a desktop system with NVIDIA GeForce RTX 2080, EGENet can reduce the number of parameters by 24 million while speeding up by 2.59×. EGENet introduces a new concept called Asymmetric Depth Dilated Separable Convolution (ADDSC), which enables a reduction in parameters and inference time while maintaining the receptive window size. A novel evaluation metric is proposed, considering frames per second (FPS), accuracy, and deployment on embedded GPU devices with constrained resources, targeting at least 98.85% accuracy and a frame rate of more than 30 FPS. Thorough evaluations were performed on the NVIDIA Jetson Xavier AGX and Jetson Nano, utilizing limited resources, to validate EGENet’s real-time performance. Evaluation of GTSRB and LISAC datasets demonstrates outperforming results, with an accuracy of 99.58% and 98.18% and a response time of 253 FPS and 90 FPS on Jetson Xavier AGX and Jetson Nano devices, respectively. Our work contributes to efficient TSC systems based on embedded GPUs and offers a comprehensive performance evaluation methodology for autonomous driving. We present exhaustive statistical comparative tests against state-of-the-art systems.

A quantitative, cross-sectional survey was conducted with 319 entrepreneurs, and the data were analyzed using structural equation modeling. The results show that openness to experience, conscientiousness, and low neuroticism significantly increase perceived happiness, while agreeableness has no effect, challenging prior assumptions. These findings contribute to the literature by identifying personality-based predictors of entrepreneurial happiness and highlight the importance of psychological resources in entrepreneurship. In practice, the study offers insights for designing support programs and public policies that foster emotionally sustainable entrepreneurial ecosystems.
