From the available studies, it can be concluded that the traditional theories of demand in tourism and the various model approaches are applied for its investigation. Therefore, a sufficient space is created for the improvement of techniques, approaches, methods, and tools that enable obtaining new outcomes for the decision-making processes and for the construction of policies. The main goal of this study was to develop a fuzzy model for evaluating the level of tourist movement to infrastructure and accessibility in the regions of the V4 countries, based on travel satisfaction relative to the expected and actual experience of participants in the tourist movement. For the first time, a model offuzu logical inference of level of travel satisfaction relative to expected and actual experience from infrastructure and accessibility is developed. The research results were tested, and the developed model was verified on real data from 2,343 participants of the tourist movement for the regions of the V4 countries. The effective policies and the efficient decision-making processes are one of the most important ways to eliminate the regional disparities and discrepancies impacting the economic, health, social, and environmental fields of each country.

While conducting the analysis, publication trends, influential authors, citations, and keywords are all taken into consideration in order to uncover the intellectual structure and development of the field. It is clear from the findings that the BSC continues to be an essential instrument for coordinating strategic goals with operational procedures. This is demonstrated by the fact that it is frequently mentioned and holds a central position in the research literature. Emerging topics such as sustainability, business intelligence, and technological integration are examples of how the focus on contemporary challenges is shifting along with the times. On the other hand, the study identifies research gaps, particularly in the areas of applications for the public sector and the incorporation of advanced digital tools.

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.

One crucial aspect of producing butadiene by the Lebedev process is the high-temperature stability of ethanol to acetaldehyde conversion. However, copper-based catalysts, despite exhibiting high activity and selectivity, suffer from sintering and coking and need to be improved for successful industrial applications. Herein, we show Cu-based (similar to 2.5 wt %) catalysts doped with Ni and Zn (0.028-0.36 wt %) to improve the catalytic performance of nanoparticles. The catalysts were prepared by hydrolytic sol-gel and dry impregnation methods. STEM analysis determined the nanoparticle sizes in the 1.9-2.8 nm range. Ni-doped catalysts outperformed the parent Cu catalysts in ethanol dehydrogenation activity at lower temperatures (185-220 degrees C) but suffered from faster deactivation. The Zn-doped catalysts exhibited improved high-temperature stability. For these materials, acetaldehyde selectivity fluctuated around similar to 90% and acetaldehyde productivity reached 3.63 g g-1 h-1 at 290 degrees C and a WHSV of 4.73 h-1. The improved stability of the Zn-doped samples was correlated with lower coke formation (XPS, TG analysis, and Raman spectroscopy).
