2. Correlation of trust and work engagement : a modern organizational approachAna Nešić, Slavica Mitrović Veljković, Maja Meško, Tine Bertoncel, 2020, izvirni znanstveni članek Opis: In modern organizations, in which changes are happening faster and more unpredictably, employees are gaining a more complex role and increasing importance. New approaches to employee insight, based on the heavy work investment concept (HWI), bring together different theoretical and practical approaches that attempt to explain the causes and consequences of certain organizational behaviors. The fundamental issue is determining whether engagement and trust, remain two of the critical factors of an organizations success, or are their roles in effectively organized systems significantly changed or reduced. This research aims to establish a correlation between trust and work engagement in on 787 respondents from 16 organizations in Serbia. Trust in organizations is measured through the dimensions of benevolence, integrity, competence and predictability. Engagement of employees is measured through the dimensions of energy, dedication and absorption. The results showed a significant correlation between dimensions of trust: benevolence/integrity and competence, with all work engagement dimensions. The strongest correlation is established between the trust dimension of benevolence/integrity and the work engagement dimension - energy. The significance of the research is reflected in the elucidation of behavioral factors of employees in organizations burdened with transitional changes.

3. Clostridioides difficile ribotype distribution in a large teaching hospital in SerbiaMiloš Korać, Maja Rupnik, Nataša Nikolić, Milica Jovanović, Tanja Tošić, Jovan Malinić, Nikola Mitrović, Marko Marković, Ankica Vujović, Sanja Peruničić, Ksenija Bojović, Vladimir V. Đorđević, Aleksandra Barać, Ivana Milošević, 2020, izvirni znanstveni članek 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.

4. Electricity prices and consumer behavior, case study Serbia - randomized control trials methodIztok Podbregar, Sanja Filipović, Mirjana Radovanović, Olga Mirković-Isaeva, Polona Šprajc, 2021, izvirni znanstveni članek Opis: The aim of this research was to identify energy saving instructions effect on household’s electricity consumption. The research was conducted using Randomized Control Trials, which implied defining a treatment and control group on a sample of 330 households. The research was carried out in Republic of Serbia, where electricity prices are the lowest in Europe and electricity is used inefficiently. For quantitative analysis of data, the Difference in Difference method was used, which compares the changes in electricity consumption over time between the treatment and control group and estimates the overall impact of the energy saving instructions. The research showed that in situations where electricity price is very low, energy saving information does not have the significant impact on change in consumer behavior. However, inefficient use of electricity might be due to the different efficiency of heating devices used. Not only that the low impact of information on energy saving habits may be a consequence of the low will to change habit, but also of the impossibility to change the habit (unless changing the heating device, but this implies expenditures). Results can be used for consideration of changes in organization and regulation of the electricity market in all South Eastern European countries (SEE).

5. GIS-based modelling reveals the fate of antlion habitats in the Deliblato SandsDanijel Ivajnšič, Dušan Devetak, 2020, izvirni znanstveni članek 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.

6. How do job-related constructs determine employee turnover? : Serbian hotels exampleMarija Cimbaljević, Milena Nedeljković Knežević, Dunja Demirović Bajrami, Milosav Dunjić, Hamid El Bilali, Milica Rančić Demir, 2020, izvirni znanstveni članek Opis: In the hospitality industry, employee turnover is extremely high. It is often caused by minimal growth opportunities, intensive work, lack of flexibility, limited opportunities for promotion, lack of recognition, etc. Investment in human resources, strategies that maintain an adequate workforce and improve employee engagement is quite justified cost with multiple returns. The specific issue is that hospitality leaders often do not know the relationships between employee satisfaction, employee motivation and employee engagement, which may be the basis for understanding their intention to leave the job. The purpose of this study was to examine the relationship between the three job-related constructs: motivation, job satisfaction, and work engagement, as well as to examine their impact on employee turnover. The results confirmed a positive relationship between job satisfaction and motivation, satisfaction and work engagement, as well as the relationship between motivation and engagement. On the other side, the results showed that job satisfaction, dedication, and vigor negatively predict employee turnover. The findings may provide hotel managers with a foundation to understand this issue and assume where to direct their research and how to improve job conditions.

7. The influence of organizational factors on the adoption of energy efficiency measures in companiesAleksandar Vučković, Marija Džunić, 2023, izvirni znanstveni članek Opis: This paper aims to research the organizational factors influencing the implementation of energy efficiency measures in companies. The analysis was performed on a sample of companies from Serbia included in the World Bank Enterprise Survey. The raw data collected by the World Bank were utilized to analyze the correlation between various organizational factors and the adoption of energy efficiency measures. The analysis revealed a statistically significant correlation between management maturity and the implementation of energy efficiency measures in companies. These findings suggest that improving energy efficiency is not an isolated process but rather closely related to the maturity of management practices, highlighting the importance of comprehensive organizational development for achieving optimal energy management.

8. Ekonomski učinki “Mini Schengena” na države zahodnega BalkanaStefan Pasinechki, 2021, diplomsko delo Opis: The concept of open borders between Western Balkan countries has gained a lot of traction in recent years. The idea gained traction after the leaders of Albania, North Macedonia, and Serbia agreed to begin implementing the "Mini Schengen" or "Open Balkans" plan, which includes opening the three nations' internal borders. In this thesis, we have analyzed the economic effects such a move will have on these three countries using already available data and studies done on Schengen Area countries. We used these studies and data to forecast the economy for the next few years if Albania, North Macedonia, and Serbia joined the Schengen or Mini Schengen in the years 2021-2025. We discovered that open borders would significantly benefit the economies, increase cooperation, and improve relations of these countries, as well as provide numerous economic opportunities for individuals and businesses.

9. Public video surveillance : a puzzling issue for Serbian lawmakersMilan Žarković, Zvonimir Ivanović, Ivan Žarković, 2016, izvirni znanstveni članek Opis: Purpose:
This paper examines the status of and practical problems in the use of public video surveillance for police and criminal procedural purposes.
Design/Methods/Approach:
The approach in this research paper entailed a comparative legal analysis of the Serbian system with regard to public video surveillance and the use of recorded material as evidence in different procedures. Our research also examined reactions to the use of such material by various government agencies, such as the Ombudsman, the Commissioner for Information of Public Importance and Personal Data Protection, as well as the procedures and activities of the police department when dealing with criminal investigations. This paper examines this issue from the perspective of the European Convention on Human Rights (ECHR), the jurisprudence of the European Court of Human Rights, and their implementation in Serbia.
Findings:
The results provide different perspectives on changes made in Serbian law. They also guided us in the interpretation of strategically important decisions and led us to construe methods and procedures for implementing different solutions and approaches in surveillance.
Research Limitations / Implications:
Although the findings of this paper are strictly connected with the Serbian legal system, their implications and proposed solutions are universal in their possible application.
Originality/Value:
While in Serbia there have already been studies covering public video surveillance, evolutionary changes in certain crucial laws have lagged behind. This paper critically deals with such strategic imperfections.

10. Prisoner rehabilitation in SerbiaŽelimir Kešetović, Biljana Simeunović-Patić, 2010, pregledni znanstveni članek Opis: Purpose:
The paper gives a brief overview of the history and past developments of prison rehabilitation in the Republic of Serbia, as well as a more detailed description of present situation in the domain of the execution of institutional penal sanctions, in both normative and practical aspects.
Design/Methodology/Approach:
For the purpose of the analysis, legislative documents were taken into account, as well as official data and reports of the Prison Administration of the Ministry of Justice and NGOs reports.
Findings:
The new treatment concept is based on the latest scientific achievements on crime and experiences of modern and developed penal systems Europe-wide. It is primarily focused on better classification of convicted persons by the level of risk, individual characteristics, needs and ability to adopt positive interventions through the penal system. Particularly important is that external control of work of penal institutions is provided, through the institution of Protector of Citizens. However there is still need of further developments in the domains of prison rehabilitation/treatments, and particularly of aftercare and post-penal assistance, in order to reach the substantial improvements in ex-prisoners’ social inclusion, reduction re-offending rates and crime prevention.
Research limitations/implications:
More reliable conclusions on overall effects of prison rehabilitations could be derived only on the basis of particularly tailored comprehensive longitudinal research. Rather new legislation and ongoing reform of the concept of prison administration are objective external research limitations.
Practical implications:
This paper emphasises the importance of after care and post-penal assistance as a problem that should be addressed in comprehensive manner by Ministry of Justice, together with other relevant ministries and agencies in Serbian government.
Originality/Value:
This paper is among few attempts of Serbian prisoner rehabilitation evaluation.
