Facial emotion recognition with AI
2024-04-23 - Ballesteros, Jesús A.; Ramírez V., Gabriel M.; Moreira, Fernando; Solano , Andrés; Pelaez, Carlos Alberto
The paper presents a work with AI on using computer vision algorithms to detect human emotions in the context of the video when the user looks at different video images. This work aims to present the development of software that detects emotions by recognizing users’ facial expressions using AI algorithms and image process pipelines. The process of seeing emotions is done by evaluating users with images, which has allowed the application of computer vision algorithms that detect images according to the authors of the discipline of psychology, who propose the emotions and how they can be recognized. In this work, it has been demonstrated that it is possible to recognize emotions with the algorithms used and the development and training of the software performed from facial expressions. However, for a correct interpretation of emotions, the system must be trained in a context with more images and other complementary algorithms that allow differentiating emotions represented by facial expressions with very similar patterns to improve certainty and accuracy.
The contribution of the labour practices to organizational performance: The mediating role of social sustainability
2024-04-18 - Lopes, João M.; Gomes, Sofia; Nogueira, Elisabete
In the fiercely competitive global business environment, the attainment of excellence is contingent upon the efficient management of human resources and their alignment with sustainable development goals. This study examines the interplay between labour practices, social sustainability and organizational performance, with a focus on the often-ignored perspectives of employees. Employees, often neglected as critical stakeholders, shape corporate values and strategy. The study uses a quantitative approach, having applied the partial least square method for the proposed research model. Questionnaire responses from 574 Portuguese employees reveal that labour practices (employee development, employee participation and equal opportunity) positively influence perceived social sustainability. Perceived social sustainability positively influences perceived organizational performance. The examined labour practices only exhibit a positive influence on perceived organizational performance when perceived social sustainability acts as a mediator. Companies must place a high priority on the perceptions of their employees to achieve social sustainability. This involves incorporating inclusive, participative and proactive policies regarding human resources policies, thereby leveraging the mutual advantages derived from labour practices. This demonstrates the pivotal role of social sustainability in companies' decision- making processes, as it substantially contributes to enhancing organizational performance. This study emphasizes the importance of integrating social sustainability to maximize organizational performance, providing valuable insights for business leaders. The original model, social sustainability-driven organizational performance, which is based on employees' perceptions, identifies labour practices as antecedents of social sustainability, and the influence of social sustainability, both directly and as a mediator, on organizational performance, is presented
