The results of empirical analyses confirm that analysed unsystematic factors, the Stock-to-Flow index (S2F), and information on the Bitcoin (BTC) are directly correlated with BTC values. These results are expected and in line with the economic theory; however, this research paper aimed to investigate the impact of unsystematic factors on the value of decentralised virtual cryptocurrency BTC. Its aim was also to analyse the reasons for significant oscillations of market values in relation to the S2F and S2FX model and thus confirm the reliability of these models in the estimation of BTC value. The research further confirms the strong influence of non-technical information directly linked with the BTC. The limitations of this paper are the lack of possibilities for examining the impact of non-technical information affecting the Bitcoin price deviation regarding the S2F model. In addition to all mentioned limitations, the research results indicate the relevance of the S2F and S2FX models and show a strong impact of (half) the information on the value of cryptocurrencies.

Non-financial reports enable corporations to demonstrate their Environmental, Social, and Governance (ESG) aspects transparently. Social aspect reports sustainability efforts in creating a positive work environment, promoting social justice and inclusion, and maintaining good relations with local communities. The primary objective of this paper is to investigate the impact of key factors (legal form, number of employees, reporting obligation, completeness, transparency, and comprehensibility) on the overall assessment of published information about the social aspects of non-financial reports of Croatian corporations. The research sample analyzed the non-financial reports of twenty corporations. There is no statistically significant difference between the key characteristics of corporations and the overall assessment of published information on social aspects based on Pearson's correlation coefficient. Chi- Square Tests confirmed that there was no statistically significant difference between mandatory and voluntary reports concerning Global Reporting Initiative (GRI) grades. The introduction of uniform European Sustainability Reporting Standards (ESRS) in sustainability reports 2024, together with this paper's results, will contribute to greater transparency in displaying companies' efforts to create a positive work environment, promote social justice and inclusion, and maintain good relations with local communities.

Green projects have become essential in contemporary econom­ic conditions due to an increasing emphasis on environmental preserva­tion and sustainable development. including investing in renewable ener­gy sources. The main aim of this study is to explore the factors influencing the economic viability of investing in photovoltaic systems, including initial investments, return on investment, access to financing, infrastructure avail­ability, maintenance costs, system reliability, price competitiveness of out­put, and the legislative framework in Croatia. The study addresses the ex­tent to which some of these factors influence the decision to invest in re­newable energy sources using photovoltaic systems. The research was con­ducted on 103 respondents who are users of photovoltaic systems. The first hypothesis, that the decision to invest in renewable energy sources by in­vesting in photovoltaic power plants is influenced not only by subsidies but also by investment returns, increased property value, increased energy in­dependence, and long-term protection against rising electricity prices is ac­cepted. The second hypothesis was not confirmed because legislative and other constraints do not affect investment decisions alongside an excellent financial investment structure.

Project Sustainable Economy is a unique project approach to busi­ness that balances and solves the project’s environmental, social, and eco­nomic aspects with the primary objective of effectively addressing the cur­rent requirements of stakeholders, according to the authors from two Project Management Institute definitions. For all projects aimed at business growth, development and sustainability, the quality of teams is crucial. This research aims to investigate the factors within project teams that have an impact on the success of sustainable business projects. The research identifies suc­cess-contributing factors in the Project Sustainable Economy, such as decision time, team dynamics, acceptance of proposed methods, a defined plan, qual­ity of relationships, successful project managers, and constructive conflict res­olution. The paper’s substantive contribution lies in empirical research con­ducted on a sample of 102 project team members. The findings underscore that enhanced communication and interpersonal relationships among team members emerge as pivotal factors fostering success within the ambit of the sustainable economy project.

S obzirom na izraženu ulogu organizacijske kulture u sektoru financijskih usluga, ovaj rad analizira povezanost organizacijske kulture i zadovoljstva poslom u hrvatskim leasing društvima,. Studije niza autora potvrđuju utjecaj radnog okruženja i razine motivacije na zadovoljstvo poslom kao posredničkom varijablom. Istraživačka tema ovoga rada je odabrana i zbog porasta značaja usluga i poslovnih aktivnosti leasing društava koja u Republici Hrvatskoj pokazuju konstantno povećanje imovine, broja i vrijednosti novih ugovora. Cilj rada je ispitati u kojoj su mjeri dimenzije organizacijske kulture – upravljanje promjenama, postizanje ciljeva, koordinacija timskog rada, orijentacija na klijente i snaga kulture – povezane s razinom zadovoljstva zaposlenika poslom. Empirijsko istraživanje provedeno je 2024. godine na uzorku od 150 zaposlenika iz 15 leasing društava putem online upitnika. Organizacijska kultura mjerena je prilagođenom verzijom OCAQ instrumenta, dok je zadovoljstvo poslom procjenjivano prilagođenim česticama iz JSS modela. Primijenjene su deskriptivna statistika i Pearsonova korelacijska analiza. Rezultati pokazuju statistički značajnu pozitivnu povezanost svih dimenzija organizacijske kulture sa zadovoljstvom poslom, pri čemu se snaga kulture ističe kao najsnažniji prediktor. Nalazi sugeriraju da jačanje zajedničkih vrijednosti te kvaliteta interne komunikacije i podrške promjenama mogu biti povezani s višom razinom zadovoljstva zaposlenika.
