1. Processed food intake assortativity in the personal networks of older adultsMarian-Gabriel Hâncean, Jürgen Lerner, Matjaž Perc, José Luis Molina González, Marius Geanta, Iulian Oană, Bianca-Elena Mihǎilǎ, 2025, original scientific article Abstract: Existing research indicates that dietary habits spread through social networks, yet the impact on populations in Eastern Europe, particularly in rural areas, is less understood. We examine the influence of personal networks on the consumption of high-salt processed foods among individuals in rural Romania, with a specific focus on older adults. Using a personal network analysis, we analyze data from 83 participants of varying ages and their social contacts through multi-level regression models. The inclusion of participants across a wider age range allows us to capture the broader dynamics of social networks, reflecting the intergenerational nature of rural communities. Our findings reveal assortativity in dietary habits, indicating that individuals cluster with others who share similar food consumption patterns. Our results underscore the need for public health interventions that account for the influence of social networks on dietary behavior, as addressing high salt intake and its associated health risks may require considering the broader social context beyond older adults. The study contributes to understanding the social determinants of dietary behaviors and highlights the role of personal networks in shaping food choices in vulnerable populations.

2. Behavioral expectations of business school students concerning extreme climate events : regional insights and implications for Southeast EuropeNikša Alfirević, Darko Rendulić, Sonja Mlaker Kač, 2025, original scientific article Abstract: Abstract: This article presents the role of environmental attitudes and self-efficacy in shaping the behavioral expectations of business students in Southeast Europe regarding extreme climate events. Conducted across twelve public and private business schools in five countries, the study provides a baseline for comparison with similar empirical research. Using multiple linear regression, we analyze the relationship between the proenvironmental attitudes and environmental self-efficacy to the students’ climate change expectations. Our results indicate that pro-environmental attitudes significantly predict the students’ expectations of extreme climate events, while environmental self-efficacy plays a secondary but statistically significant role. These findings extend the extant literature by focusing on the role of sustainability in business school curricula and the potential positive outcomes of experiential learning methods and approaches.

3. First record of the Asian seed beetle Megabruchidius dorsalis (Fåhræus, 1839) (Coleoptera, Chrysomelidae, Bruchinae) in CroatiaEva Horvat, Nina Šajna, 2021, original scientific article Abstract: The seed beetle Megabruchidius dorsalis is an alien species first found in Europe in 1989 in Italy. Since then, it has been recorded in many European countries, developing inside the seeds of the ornamental trees Gleditsia triacanthos and Gymnocladus dioicus. Mature G. triacanthos pods were collected from the ground in Zagreb, Croatia in February 2020. Four adult specimens of M. dorsalis emerged from the collected material by the end of May 2020, which confirms the first record of this species in Croatia. We also provide a temporal distribution map of M. dorsalis and another species, M. tonkineus, in Europe.

4. Additional records of Megabruchidius dorsalis (Fåhræus, 1839) (Coleoptera, Chrysomelidae, Bruchinae) in Zagreb, CroatiaEva Horvat, Mirjana Šipek, Nina Šajna, 2022, original scientific article Abstract: In this paper, we report two new locations of the alien invasive seed beetle Megabruchidius dorsalis in Zagreb, Croatia. Additionally, we confirm for the second time the presence of M. dorsalis at one location in the same city. All beetles were reared from mature Gleditsia triacanthos pods collected from the ground (three locations) and from trees (one location). These records contribute to the knowledge of the distribution of M. dorsalis in Europe.

5. Big data usage in European Countries : cluster analysis approachMirjana Pejić Bach, Tine Bertoncel, Maja Meško, Daila Suša-Vugec, Lucija Ivančić, 2020, original scientific article Abstract: The goal of this research was to investigate the level of digital divide among selected European countries according to the big data usage among their enterprises. For that purpose, we apply the K-means clustering methodology on the Eurostat data about the big data usage in European enterprises. The results indicate that there is a significant difference between selected European countries according to the overall usage of big data in their enterprises. Moreover, the enterprises that use internal experts also used diverse big data sources. Since the usage of diverse big data sources allows enterprises to gather more relevant information about their customers and competitors, this indicates that enterprises with stronger internal big data expertise also have a better chance of building strong competitiveness based on big data utilization. Finally, the substantial differences among the industries were found according to the level of big data usage.

Logistični procesi pri nabavi kemijskih materialov v podjetju Hisense Gorenje EuropeKlara Šmon, 2023, undergraduate thesis Abstract: Diplomsko delo smo razdelili na dva dela: teoretični in praktični. V teoretičnem delu smo opredelili, kaj je to logistika, opisali logistične podsisteme in elemente logistike s poudarkom na nabavni logistiki. V praktične delu pa se bomo omejili na logistične procese pri nabavi kemijskih elementov v podjetju Hisense Gorenje Europe.
Metode, ki smo jih pri raziskovalnem delu uporabili bodo poslovne, saj bomo v diplomski nalogi proučevali poslovno (nabavno) funkcijo podjetja. Uporabljene metode se lahko opredeli tudi kot dinamične, saj se poslovne funkcije spreminjajo in prilagajajo okoliščinam poslovanja. K raziskovanju smo pristopili deskriptivno, saj bomo s pomočjo strokovne literature in spletnih virov opredelili logistiko, opisali njene podsisteme in elemente. Podatke za pripravo diplomskega dela smo pridobili s pomočjo intervjuvanja mentorja, ki nam ga je dodelilo podjetje.
Hipoteza iz katere smo izhajali je bila, da dobro organizirana nabavna logistika pozitivno vpliva na delovanje podjetja Hisense Gorenje Europe.
Keywords: logistika, nabava, Hisense Gorenje Europe, skladiščenje, transport, logistični procesi.

7. Impact of car sharing on urban sustainabilityVasja Roblek, Maja Meško, Iztok Podbregar, 2021, review article Abstract: The article gives us an insight into the key issues of car sharing and its impact on urban sustainability. A selection of 314 articles published in peer-reviewed journals from the Scopus database were analysed using Leximancer 5.0 for Automated Content analysis. A total of seven themes were identified explaining the researched topic of the car sharing situation in Europe, which are sharing, economy, model, systems, electrical car sharing, policy and travel. There are two ways of sharing owned cars in Europe; access to cars from the fleet of private organisations and P2P car sharing. Sustainable environmental solutions in the context of the electrification of cars are used. Car sharing usually takes place online and can be free or for a fee as defined by The European Economic and Social Committee. The article provides an overview of understanding the concept of urban car sharing in Europe.

8. Factors affecting attitudes towards COVID-19 vaccination : an online survey in SloveniaLuka Petravić, Rok Arh, Tina Gabrovec, Lucija Jazbec, Nika Rupčić, Nina Starešinič, Lea Zorman, Ajda Pretnar Žagar, Andrej Srakar, Matjaž Zwitter, Ana Slavec, 2021, original scientific article Abstract: While the problem of vaccine hesitancy is not new, it has become more pronounced with the new COVID-19 vaccines and represents an obstacle to resolving the crisis. Even people who would usually trust vaccines and experts now prefer to wait for more information. A cross-sectional online survey was conducted in Slovenia in December 2020 to find out the attitudes of the population regarding COVID-19 vaccination and the factors that affect these attitudes. Based on 12,042 fully completed questionnaires, we find that higher intention to get vaccinated is associated with men, older respondents, physicians and medical students, respondents who got the influenza vaccination, those who knew someone who had gotten hospitalised or died from COVID-19 and those who have more trust in experts, institutions and vaccines. Nurses and technicians were less likely to get vaccinated. In answers to an open question, sceptics were split into those doubting the quality due to the rapid development of the vaccine and those that reported personal experiences with side effects of prior vaccinations. Although the Slovenian population is diverse in its attitudes towards vaccination, the results are comparable to those found in other countries. However, there are potential limitations to the generalizability of the findings that should be addressed in future studies.

9. What drives the usage of management tools supporting industry 4.0 in organizations?Zlatko Nedelko, 2021, original scientific article Abstract: The main purpose of this study was to examine how personal and organizational drivers influence the utilization of management tools aimed at supporting organizational working in Industry 4.0 settings. We built our research upon the recognized importance of management tools for organizational working under Industry 4.0 settings and explored the key personal and organizational drivers of management tool usage. Calculations were performed based on the responses of 222 employees working in organizations across Europe. The results revealed that, among personal drivers, a higher level of education leads to significantly higher usage of six sigma, rapid prototyping, outsourcing, customer relationship management, knowledge management, core competencies, and strategic planning. More experienced employees use significantly more six sigma, total quality management, supply chain management, knowledge management, and core competences than their less experienced peers. The impact of organizational drivers is substantially weaker, where only industry shows significant influence, indicating that lean production, six sigma, and supply chain management are used more in manufacturing than in service organizations. Gender, one’s position in the organization, and the organization size do not play a substantial role in management tool usage. Managers should recognize the role of personal and organizational drivers of management tool usage in order to more quickly implement Industry 4.0 principles in organizations.

10. Knowledge, attitude and behaviour of university students regarding salt and iodine: a multicentre cross-sectional study in six countries in Europe and AsiaGeorgios Marakis, Antonios Katsioulis, Lamprini Kontopoulou, Anke Ehlers, Katharina Heimberg, Karen Ildico Hirsch-Ernst, Tomaž Langerholc, Hanna Adamska, Ewa Matyjaszczyk, Renuka K. D. Silva, Chathurika K. A. Madumali, Tai-Sheng Yeh, Ling-Jan Chiou, Mei-Jen Lin, Georgios Karpetas, Anke Weissenborn, 2021, original scientific article Abstract: Background: Strategies to reduce salt intake are encouraged to be implemented in parallel with those that aim to ensure iodine adequacy at the population level. The aim of the present study was to assess and compare knowledge, attitudes and behaviours related to salt and iodine among students in Europe and Asia.
Methods: A multicentre cross-sectional study was conducted with 2459 university students in total (42.7% males, median age 21 years) from four countries in Europe and two countries in Asia. Data were collected with the use of a self-administered questionnaire, and univariate and multivariate statistical analyses were performed to explore any association between variables.
Results: Only 6.5% of all participants knew the correct salt recommendations. Nearly a quarter of them (24.4%) found salt recommendations confusing and/or contradictory. There were significant differences between European and Asian participants, with those from Europe being better informed about salt recommendations, but significantly less knowledgeable about iodine. The reported frequency of use of salt and salt-containing sauces either at the table or for cooking, as well as knowledge about ways to reduce salt intake among those who indicated to make conscious efforts to do so, differed significantly between countries. Significant differences between countries were also observed with respect to the type of salt used, with about one third of all participants (34%) not being aware of the kind of salt they used.
Conclusion: The results of this survey highlight serious salt- and iodine-related knowledge gaps among university students in Europe and Asia. Raising awareness and conducting information campaigns is needed to promote changes in behaviour that would result in a reduction of salt intake and conscious use of iodised salt at the individual level.
