1. Socio-demographic and health factors drive the epidemic progression and should guide vaccination strategies for best COVID-19 containmentRene Markovič, Marko Šterk, Marko Marhl, Matjaž Perc, Marko Gosak, 2021, original scientific article Abstract: We propose and study an epidemiological model on a social network that takes into account heterogeneity of the population and different vaccination strategies. In particular, we study how the COVID-19 epidemics evolves and how it is contained by different vaccination scenarios by taking into account data showing that older people, as well as individuals with comorbidities and poor metabolic health, and people coming from economically depressed areas with lower quality of life in general, are more likely to develop severe COVID-19 symptoms, and quicker loss of immunity and are therefore more prone to reinfection. Our results reveal that the structure and the spatial arrangement of subpopulations are important epidemiological determinants. In a healthier society the disease spreads more rapidly but the consequences are less disastrous as in a society with more prevalent chronic comorbidities. If individuals with poor health are segregated within one community, the epidemic outcome is less favorable. Moreover, we show that, contrary to currently widely adopted vaccination policies, prioritizing elderly and other higher-risk groups is beneficial only if the supply of vaccine is high. If, however, the vaccination availability is limited, and if the demographic distribution across the social network is homogeneous, better epidemic outcomes are achieved if healthy people are vaccinated first. Only when higher-risk groups are segregated, like in elderly homes, their prioritization will lead to lower COVID-19 related deaths. Accordingly, young and healthy individuals should view vaccine uptake as not only protecting them, but perhaps even more so protecting the more vulnerable socio-demographic groups.

2. Examining determinants of leadership style among Montenegrin managersAnđelko Lojpur, Ana Aleksić, Sanja Vlahović, Mirjana Pejić Bach, Sanja Peković, 2015, original scientific article Abstract: As a leader’s behavior can have a strong impact on different employee work- related outcomes, various approaches have been put forth in an effort to determine the most effective form of leadership and determinants of individuals’ choice of leadership style. This paper analyzed whether one’s choice of leadership style is due more to personal or organizational characteristics. We used survey data to investigate the determinants of leadership style among Montenegrin managers. Our analysis showed that, although demographic characteristics such as gender, age, and education do not influence the choice of leadership style, internal organizational characteristics such as hierarchical level, managerial orientation to tasks/people, and decision-making characteristics such as decision- making style and decision-making environment are positively associated with the choice of democratic leadership style. This contributes to recent research in leadership that shows how some personal characteristics are considered to be less important in developing certain styles and that the choice of style is more dependent and contingent on external influences and situations.

3. The demographic ageing of population in Bosnia and Herzegovina : causes and consequencesAlma Kadušić, Alija Suljić, Nedima Smajić, 2016, original scientific article Abstract: In this paper the age structure and the ageing population process in Bosnia and Herzegovina in the second half of the 20th century and the beginning of the 21st century is analyzed. The main reasons that caused changes in the age composition of the population and the population ageing in Bosnia and Herzegovina have been researched. The main causes of the population ageing in Bosnia and Herzegovina in the second half of the 20th century were primarily trends in fertility rates and secondarily trends in mortality rates. The economic growth of Bosnia and Herzegovina after World War II conditioned changes in the economic and educational structure of the population and with that the changes in the natural increase rates and migration balance. The war was the main cause of negative demographic changes in Bosnia and Herzegovina in the period from 1992 to 1995, and the post-war adverse socioeconomic, political and other circumstances have been the cause of negative demographic trends after 1995. The aim of this paper is to determine the level of population ageing in Bosnia and Herzegovina and the consequences this process could have on the demographic future of this country.

4. Rural amenity and rural change in temperate Australia : implications for development and sustainabilityNeil Argent, Matthew Tonts, Roy Jones, John Hubert Holmes, 2009, original scientific article Abstract: Many rural areas in the developed world are experiencing planning and development challenges related to processes of population change. The nature, direction and regional manifestations of these changes are strongly related to the varying levels of local amenity. These result from the qualities of the local social, economic and physical environments and contribute to the ability of rural regions to attract and retain residents. In turn the presence or absence of this attractive ability is likely to engender development and sustainability challenges related to growth, decline or (where the attractive forces are demographically specific) social mix. This paper considers these challenges in the context of high amenity rural regions in temperate Australia.

5. Influence of demographic factors on employee satisfaction and motivationSnežana Urošević, Milijić Nenad, 2012, original scientific article Abstract: Nowadays, human resource management and development is becoming more significant due to the fact that a man has gained a new place and a new role in all social processes and in their management. The sheer employees' characteristics, i.e., demographic factors, besides the organisational factors, have a certain influence in this area. By adequate understanding of both demographic factors and their influence, it is possible to apply measures to make the employees satisfied and motivated. This paper points out such influences on the employees' satisfaction and motivation. Also, the interaction of certain demographic factors is presented, such as the professional qualification, years of working experience and age, onto employees perceiving satisfaction and motivation and onto respective consequences. In order to determine the employee satisfaction and motivation, the responses from the employees to questions divided into six groups (material conditions, security, acceptance and social component, respect and status, self-confirmation and loyalty), were used. The research was done on a set of 328 employees in the telecommunications sector in Serbia.

6. Correlates of depression in the slovenian working populationZalika Klemenc-Ketiš, Borut Peterlin, 2013, original scientific article Abstract: This multicentre, cross-sectional observational study aimed to determine the prevalence of depression among the working population of Slovenia and identify factors correlating with higher prevalence of depression. It was conducted in three occupational medicine practices within major Slovenian primary health care centres. The study population consisted of 1,474 respondents [73.7 % of the invited participants, 889 (60.3 %) men and 585 (39.7 %) women with mean age of (40.5±9.8) years] who visited these practices for their regular check-ups from November 2010 to June 2012 and were asked to fill in a self-developed questionnaire and score depression on the Zung’s self-rating depression scale. According to the rating, 50 (3.4 %) respondents suffered from depression. In the multivariate analysis, depression correlated with the following independent variables: self-perceived exposure to chronic stress, positive family history of depression, and primary school education.
