Prosocial rule-breaking and public value in public procurement: informal practices in pre-tender design and post-contract continuity

Purpose This paper aims to examine how three informal practices in Portuguese public procurement – informal suggestion of invitees, supplier input to specifications and indirect continuity of incumbent resources – emerge and become justified in a highly regulated procurement envi...

Self-sacrificing mothers or empowered sexual subjects? Tensions between motherhood and sexuality in the construction of mothers’ erotic experiences and identities

Western representations of motherhood have historically existed in tension with those of female sexuality, as exemplified by the 'madonna-whore' dichotomy. This paper's goal was to understand the cultural tension between discourses of female sexuality and motherhood and attempt t...

Artificial Intelligence and AI-Adjacent Digital Technologies in Nursing Practice Within Gastroenterology: A Scoping Review of Current Applications, Challenges, and Future Directions

Background/Objectives: Artificial intelligence (AI) is increasingly integrated into clinical gastroenterology, with emerging applications in nursing contexts. However, the extent and nature of these applications in gastroenterology nursing remain under-explored. This scoping revi...

Structure-aware feature-to-image encoding with convolutional neural networks improves peer-to-peer credit default prediction compared with conventional tabular models

Abstract Background Peer-to-peer (P2P) lending has expanded rapidly, exposing individual investors to credit default risk typically absorbed by traditional bank intermediation. Methods This study proposes a hybrid deep learning framework for credit default prediction using 1,335,...

What explains global patterns of climate activism? A macro-level, cross-national analysis of collective environmental action

Activism in response to climate and ecological breakdown is a defining feature of 21st-century societies. Yet, the factors underpinning its global variation remain insufficiently understood. We address this research puzzle through a cross-national analysis of collective environme...

Typology and critical analysis of structural and institutional barriers to sustainable intensification education in Nigeria and Ghana: A systematic review

Background The ongoing issues of food insecurity, poverty, and environmental degradation in West Africa make sustainable intensification (SI) essential. To combat these challenges, scholars and policymakers increasingly agree that training and education in SI is necessary, partic...

“Uroboros” circle: a multilevel study on leader–follower and follower–leader crossover

Purpose The literature on the crossover theory (Westman, 2001) typically focuses on how leaders influence followers’ well-being by exchanging psychological states and resources (Hobfoll et al., 2018). However, the role of followers in influencing leaders’ well-being has been less...

Women's entrepreneurship and resilience: focusing on a Central European entrepreneurial setting

Purpose Despite extensive research on resilience in established organizations, scholarship intersecting entrepreneurial resilience and women's entrepreneurship has been slow to progress. Much of the academic discourse within this research stream often centres on women's negative...

Through the door or the looking glass? Comparing in-person and virtual hospital clowning impact on parents’ anxiety and children’s negative emotions

Abstract This study compared in-person and virtual hospital clown interventions to a control group, assessing children’s negative emotions and parental anxiety before and after intervention. Ninety-five children (52 girls, aged 4–17, M = 9.75) and their parents were assigned to i...

Boosted training strategy for physics-informed neural networks in modeling non-linear computer virus dynamics with vertical transmission

Computer-virus propagation in networked systems is often modeled by epidemic-type derivative equations. Still, standard quantitative solvers can become computationally demanding and may exhibit small stability for long-term predictions. This work develops a Physics-Informed Neura...

Revisiting the association between musical expertise and second-language proficiency

Abstract Musical expertise is frequently correlated with second-language (L2) proficiency, but it remains unclear whether this association generalizes across languages and measures. Here, we examined links between musical expertise and L2 proficiency among native speakers of Port...

Between Individual Belief and National Context: Relative Positioning and Expectations of Collective Climate Action in Europe

Expectations regarding collective climate action are multidimensional and should be understood in relation to the social contexts in which they are embedded. This study examines whether these expectations are associated with the country-level average belief in the anthropogenic o...
