The paper points out the leading role of the HR department in crisis situations, with special emphasis on the crisis caused by the COVID-19 pandemic, which affected the whole world in early 2020. Regardless of the intensity and form in which they occur, crises threaten the functioning and survival of organizations. The HR department is an important factor in the successful functioning of organizations and, in a period of crisis, this department takes a leading role in the process of crisis management and subsequent recovery. During COVID-19 pandemic, the HR department of every organization had to confront new challenges in order to protect the health of employees, while ensuring the normal functioning of organizations. In order to find out how this department dealt with crisis that occurred, empirical research with a specially designed questionnaire was conducted and filled in by 108 respondents from Serbia, Bosnia and Herzegovina, and Croatia in 2020. The research results showed that HR department has taken a leading role in preserving the health and safety of employees, as well as in the process of adapting organizations to function in crisis conditions. According to results, the key activities carried out by the HR department in organizations are work from home (wherever the nature of the work allowed), flexible working hours, reorganization of the working space to achieve the required physical distance between employees, improved hygiene measures, etc. In addition, the research results showed that, during the global COVID-19 pandemic, the HR departments took an active role in providing psychological assistance to employees to adapt to new conditions and ways of working.

: The objective of this study was to test the inhibitory effect of five newly synthesized arylmethylene-bis(3-hydroxy- 5,5 -dimethylcyclohex-2-en-1- one) derivatives. The structural characterization and stereochemistry of synthesized compounds were deduced from analyses of experimental FT- IR, 1 H, 13 C NMR spectra and theoretical methodology of DFT study based on the global chemical reactivity indices calculated using the 6- 31G** level of theory. the stability of the newly synthesized compounds, the reactivity descriptors obtained at B3LYP level ( E gap , dipole moment, μ , η , ω ) were computed. The docking study and the selected quantum chemical descriptors computed for compounds 1 −5 exhibit a good agreement. The strongest inhibitors showed 25 to 30 % inhi bition of tyrosinase activity. Results were supported by docking studies of the binding of the strongest inhibitors to the enzyme. The results suggest that tetraketones of this type, due to their tyrosinas e inhibitory effect, represent potential agents in the treatment of various types of melanomas and skin hyperpigmentation. 189.42 3´), 190.75 - C -1´).

Th is article presents the results of testing the social-entrepreneurial intention model on a student sample at the University of Bihać. Th e classical model of the Th eory of planned behavior was used as a theoretical framework. Regression analysis determined that signifi cant direct predictors of social entrepreneurial intention are personal attitude towards social entrepreneurship ( β =0.212; p=0.007) and perceived behavioral control ( β =0.644; p=0.000), while subjective norms were not confi rmed as a statistically signifi cant direct predictor. Th e model explains 54.4% of the variance of social entrepreneurial intention. 53.8% of respondents have an entrepreneur in their close family. Students who have an entrepreneur in their immediate family achieve statistically signifi cantly higher values in perceived behavioral control, but also statistically signifi cantly lower values in personal attitude, compared to students who do not have a close person who is an entrepreneur. Th at is, students who have a person in their close family who is an entrepreneur, compared to students who do not have such a person, may feel more capable of starting a social entrepreneurial venture, but they may also have a lower degree of desirability to become social entrepreneurs. Due to the lack of quantitative studies in the fi eld of social entrepreneurship, which is still in the phase of building theoretical models, we believe that the results of testing the model of social entrepreneurial intention, presented in this article, will contribute to a better understanding of the application of the theory of planned behavior in the fi eld of social entrepreneurship.

Purpose: This paper examines direct and serial indirect effects of creativity supported at the university on male and female entrepreneurial behavior through entrepreneurial self-efficacy and individual entrepreneurial intent. Methodology: The hypothesized model (which we tested) was a serial mediation model with two mediators. To examine the question of whether the relationship between variables varies by gender, model 6 in PROCESS macro (Hayes, 2018) was utilized separately for male (n = 218) and female (n = 385) students from nine different universities in Bosnia and Herzegovina. Results: Serial mediation of entrepreneurial self-efficacy and individual entrepreneurial intent in the relationship between creativity supported at the university and student entrepreneurial behavior were supported in both male and female samples. Conclusion: Serial mediation analyses indicated that a higher level of creativity supported at the university will improve student entrepreneurial self-efficacy, which may increase their entrepreneurial intent, and consequently, their entrepreneurial behavior. When the university encourages students to produce new ideas and examine old problems in new ways, it improves student confidence in their ability to mobilize cognitive, motivational, and behavioral facilities to perform entrepreneurial tasks successfully, and, in response, students demonstrate a higher level of individual entrepreneurial intent and a greater propensity for entrepreneurial behavior. However, it should be noted that an indirect effect of UC on EB only through EI was not significant in the female sample, which highlights the importance of ESE in the relationship between UC, female EI, and female EB. The results opened up a new field of research on how other types of creativity and other types of university support may affect students’ entrepreneurial behavior.
