Methodology: The cross-sectional study included a sample of 25 teams (N = 135) from various economic sectors in Slovakia. We conducted multilevel correlation and regression analyses, factor analyses, and structural modelling. Results: The multilevel correlation analysis showed positive correlations with job satisfaction for all scales of the Bochum Inventory of Personality (ranging from 0.097 to 0.406), 10 of which were statistically significant. The results indicate that job competencies predict job satisfaction, and that job satisfaction correlates positively with employees' organisational citizenship behaviour. However, the moderating effect of organisational agility on the relationship between job competencies and job satisfaction could not be demonstrated. We found a statistically significant positive relationship between the maturity level of agility and job satisfaction. We discuss possible causes, highlight the limitations, and suggest implications. Conclusion: Appropriate professional skills and a people-centred approach are key to long-term success in a competitive environment and, along with organisational agility, can contribute to employee job satisfaction. 2026-01-01T00:00:00Z http://hdl.handle.net/10563/1012814 Environmental transparency: A catalyst for SMEs’ environmental disclosure and financial outcomes Afful, Charles Randy; Dvorský, Ján Environmental transparency enhances corporate competitiveness, as legal constraints and stakeholder demands have increased global interest in ethical business practices. This study examines 302 Ghanaian manufacturing small and medium-sized enterprises (SMEs) in an emerging market context. This study investigates the impact of environmental disclosure (ED) and corporate reputation on the financial performance (FP) of SMEs. We adopted a quantitative approach through hypothetical testing, using partial least squares structural equation modeling (PLS-SEM) and the purposive sampling technique. Our findings show that ED and business reputation (BR) influence the financial success of SMEs in emerging markets. Additionally, business strategies positively moderate BR and ED. The results indicate that ED practices can guide managerial policies through regulatory compliance in meeting United Nations Sustainable Development Goals targets and improve environmental transparency and reputation demanded by stakeholders. A strategic policy alignment with the firm’s ED framework influences SMEs’ environmental transparency, competitiveness, and FP, offering both theoretical and practical insights for SMEs. © 2026 International Council for Small Business. 2026-01-01T00:00:00Z http://hdl.handle.net/10563/1012816 Migration Models Based on Diffusion and Determinants Gradients: Beyond the Gravity Theory Martyniuk, Petro; Vasa, Laszlo; Mishchuk, Halyna; Silberg, Slavka The article proposes an alternative approach to study migration flows based on gravity models. This approach does not reject gravity theory; on the contrary, it expands it to some extent. The relevant models are suggested to be described using diffusion-convection approaches. The intensity of human flows is proposed to identify on the basis of determinant gradients, and the very structure of the domain for studying these processes can be represented as a graph with nodes in the form of continuous areas of social space. The proposed approach is suitable for different dimensions of mobility studying, i.e. permanent migration decisions, touristic flows, academic mobility, transportation etc. The developed conceptual approach and mathematical formalization allow for understanding the patterns of migration applying fundamental principles of mathematic physics for economic processes. © 2025, Bucharest University of Economic Studies.

Their reliable use in outdoor environments, however, requires a clear understanding of how natural weathering influences their performance and durability. While most previous research has addressed long-term or accelerated ageing conditions, the onset of environmental degradation of MRE remains insufficiently explored. Therefore, this study investigated the early-stage degradation of MRE, embedded with irregular electrolytic iron particles (MRE-EIP) over six weeks of natural weathering exposure. Weekly samples (W0-W6) were analysed using vibrating sample magnetometer (VSM), rheometer and low vacuum scanning electron microscope and the results were correlated with weathering data from the Malaysian Meteorological Department, Kuala Lumpur. The saturation magnetization, Ms finding shows minimal change from 111.63 Am2/kg in W0 to 113.79 Am2/kg in W6, likely attributed to the exposure of EIP following the removal of the aged localized surface over the six week exposure. Strain sweep results meanwhile, revealed the progressive stiffening, with the storage modulus (G′) increased from 0.22 MPa (W0) to 0.53 MPa (W6), accompanied by a narrowing linear viscoelastic (LVE) region, indicative of early embrittlement of the samples. Nevertheless, a temporary reduction in G′ for W3 suggested a moisture-induced plasticisation, from increased rainfalls that week. Besides, the absolute MR effect, ΔG′ increased from 0.23 MPa (W0) to 0.34 MPa (W6), indicating greater responsiveness of exposed EIP to the magnetic fields which enhanced the G′ accordingly. Morphological analysis confirmed the development of localized surface depressions suggests combine effects of UV-driven embrittlement and moisture plasticisation from rainfall, leading to localised EIP exposure, while the cross-sectional structure integrity remained intact. These findings provide the first detailed account of early-stage degradation in MRE-EIP under natural weathering, offering valuable insights into early failure mechanisms and guiding durability driven material design for outdoor smart material applications. 2026-01-01T00:00:00Z
