Opis: Background and purpose: The purpose of this research is to examine how Machiavellianism and the desire for money can influence entrepreneurial intentions. It could be assumed that the desire for money and Machiavellian tendencies can develop the desire for success in people and eventually entrepreneurial intention. Methodology: Respondents were surveyed using a questionnaire. Four hundred students were from three faculties at two universities in Serbia responded the questionnaire. The study utilized Smart PLS software. Results: It was shown that there is a statistically significant positive impact of Machiavellianism and money intention on entrepreneurial intentions. Money intention is also a mediator in the relationship between Machiavellianism and entrepreneurial intentions. The theoretical contribution of the research is that these influences on entrepreneurial intentions have not been sufficiently examined so far, especially the influence of money intention. The practical significance of the research is the observation of the possibility that people who have a high level of Machiavellianism and money intention can be identified, understood, and systematically directed towards entrepreneurship. Conclusion: Although the observed characteristics can be considered negative, people who possess them also possess entrepreneurial potential, and can create social good. These motives are not desirable, but such people can be useful for society: it is certainly better to spend energy on entrepreneurial ventures and further development of their own company, than on something else, less useful, or even destructive.

Opis: The research presented in this paper aims to determine to what extent hotels in Serbia use social media components on their websites. A total of 378 hotel websites in the Republic of Serbia were analysed. For each analysed hotel, the following attributes were observed: region, category, type, and size of the establishment, while the presence of valid links to social networks, the presence of a blog, Google Map, or a link to it, and the number of versions of the site in a foreign language were analysed on their websites. Descriptive statistics and the chisquare test were applied in data processing. The research has shown that hotels in Serbia insufficiently use social media components on their websites. These findings can be useful for hotels as they may indicate ways to improve their websites.

Opis: This paper examines sustainable industrial practices in Serbia, particularly in the mining and energy sector, focusing on the potential of flotation tailings and fly ash, as materials with the largest share in disposed waste in Serbia in 2023 (95%). It highlights the environmental challenges of mining waste and explores innovative approaches to waste management within the circular economy framework. The study analyzes the current state of mining waste in Serbia, particularly in copper mining regions in the east of the country. It discusses the potential for metal recovery from waste and its reuse in various industries. The research also investigates the use of fly ash from thermal power plants as a valuable resource in the construction industry and other sectors. The paper reviews existing initiatives and legislation in Serbia in order to promote sustainable mining practices and waste utilization. By presenting case studies and potential applications, the study demonstrates how implementing circular economy principles in the mining sector can contribute to environmental protection, resource conservation, and economic growth in Serbia. The comprehensive overview of the current state in Serbia provides a solid foundation for establishing a higher degree of circularity in the mining and energy sectors.

Opis: Background: The global epidemic of nosocomial diarrhea caused by Clostridioides (Clostridium) difficile started in 2000, with high mortality rates and emergence of a new hypervirulent strain NAP1/BI/027. The aim of this study was to assess the presence of ribotype 027 and other C. difficile ribotypes in a Serbian University Hospital, compare the temporal variability of ribotypes 3 years apart, as well as to compare clinical, demographic and laboratory characteristics and disease outcome among patients infected with 027 and non-027 ribotype. This was a prospective observational cohort study addressing 4-month intervals during 2014/2015 and 2017/2018. Results: Ribotyping was performed in 64 non-duplicate C. difficile strains. Ribotype 027 was the most prevalent, and was detected in 53 (82.8%) patients (43/45 and 10/19 patients in 2014-2015 and 2017/2018, respectively). Other detected ribotypes were 001/072 in 4 (6.3%), 002 in 4 (6.3%), 014/020 in 2 (3.1%) and 176 in 1 (1.5%) patient. The percentage of the patients infected with ribotype 027 significantly decreased during the 3-year period, from 95.6 to 52.6% (p < 0.001). Ribotype 027 infection was associated with fluoroquinolone treatment more frequently than infection with other ribotypes [33 (62.3%) vs. 2 (18.2%), p = 0.010)]. A severe C. difficile infection was diagnosed more often in patients with the detected ribotype 027 compared to those infected with non-027 ribotypes (p = 0.006). No significant difference in the mortality and recurrence rates was found between the patients infected with ribotype 027 and those infected with other ribotypes [10/53 (18.8%) vs. 2/11 (18.2%), p = 0.708, and 10/35 (28.6%) vs. 0/2 (0%), p = 1.000, respectively]. Conclusion: Clostridium difficile ribotype 027 was the most prevalent ribotype among patients in a large Serbian hospital, but there is a clear decreasing trend.

Opis: The Deliblato Sands Special Nature Reserve (DSSNR; Vojvodina, Serbia) is facing a fast successional process. Open sand steppe habitats, considered as regional biodiversity hotspots, have drastically decreased over the last 25 years. This study combines multi-temporal and -spectral remotely sensed data, in-situ sampling techniques and geospatial modelling procedures to estimate and predict the potential development of open habitats and their biota from the perspective of antlions (Neuroptera, Myrmeleontidae). It was confrmed that vegetation density increased in all parts of the study area between 1992 and 2017. Climate change, manifested in the mean annual precipitation amount, signifcantly contributes to the speed of succession that could be completed within a 50-year period. Open grassland habitats could reach an alarming fragmentation rate by 2075 (covering 50 times less area than today), according to selected global climate models and emission scenarios (RCP4.5 and RCP8.5). However, M. trigrammus could probably survive in the DSSNR until the frst half of the century, but its subsequent fate is very uncertain. The information provided in this study can serve for efective management of sand steppes, and antlions should be considered important indicators for conservation monitoring and planning.
