Affective mechanisms linking role ambiguity to employee turnover

Purpose: This study relied on the job demands and resource model to understand employees’ turnover intentions. Recent studies have consistently lent support for the significant association between role ambiguity and turnover intentions; however, only a handful of studies focused on examining the potential mediators in this association. We argued that role ambiguity positively influences turnover intentions thro...

Harmonizing emotions in the workplace: Exploring the interaction between emotio...

The globalized environment has undeniably provided new opportunities for organizational growth. This expansion has brought about various changes that are reflected in the way cultural diversity is managed (Inegbedion et al., 2020). The ability to understand and manage emotions, both one's own and those of others, is essential for building effective relationships in multicultural teams (Brett et al., 2020). Ther...

Mobile augmented reality games for authentic science learning: perspectives of ...

The use of mobile devices in formal learning situations is a controversial issue as it is widely associated with leisure time and distraction, although it can be used to engage, enhance, complement, and even redefine learning strategies. In a technology-driven society, teachers can take advantage of the pervasiveness of technological devices to innovate their pedagogical practices to promote student engagement ...

Mobile augmented reality app with 3D models: the EduCITY app

The use of Augmented Reality (AR) technology has recently improved education and training methods. This technology has provided alternatives to the way people learn and relate to their environment. This work-in-progress study presents an approach to develop a smart learning city environment using AR games to change citizens’ sustainable development competences, the EduCITY. The EduCITY – “Smart and Sustainable ...

Fuzzy-Set QCA on Performance and Sustainability Determinants of Ports Supportin...

The present study explores the relationship between the characteristics, performance, and sustainability of ports that will, in the future, support the logistical chains of new floating offshore wind farms, considering the crucial advancement and expansion of the offshore wind energy sector for the transition to a low-carbon economy. Through a detailed analysis, which includes international case studies in Amer...

Unfocused laser ignition of high-pressure He–H2-O2 combustible mixtures

We report consistent ignition of high-pressure (p(fill)>20-30 bar) hydrogen-oxygen mixtures diluted with helium in two different combustion vessels, using an unfocused Nd:YAG laser. This corresponds to laser irradiances several orders of magnitude below the minimum ignition energies reported in the literature. This unusual phenomena has led us to try to measure the amount of laser radiation absorbed by the gas ...

The role of satisfaction with the performance appraisal: A comparative study be...

Purpose – To study in Portugal (a) whether satisfaction with the performance appraisal (PA) differs depending on the sector where the workers perform their functions (private versus public), and (b) whether the relationship between workers’ perception of usefulness and accuracy of the performance appraisal process (PAP) and satisfaction with the outcome of their last PA is mediated by their satisfaction with th...

Multitask and transfer learning for cardiac abnormality detection in heart sounds

We present a deep learning model for the automatic detection of murmurs and other cardiac abnormalities from the analysis of digital recordings of cardiac auscultations. This approach was developed in the context of the George B. Moody PhysioNet Challenge 2022. More precisely, we consider multi-objective neural networks, with several Transformer blocks at their core, trained to perform 3 distinct tasks simultan...

Synthesis and antimicrobial activity of a new class of azoimidazoles

Synthesis and antimicrobial activity of a new class of azoimidazoles

The emergence of infectious diseases caused by new pathogens or multidrug-resistant (MDR) strains has been a global health threat over the last decades.1 These infections are among the most severe healthcare problems and have been associated to several deaths and heavy economic burden per year.2,3 The imidazole ring is present in several natural and synthetic molecules with biological activity namely on effecti...
