Keeping in mind the fact that organizations in the region of Vojvodina are moving from a negotiated to market economy, this study aims to analyze how the dimensions of collaborative climate affect the various activities of knowledge management. The degree to which collaborative climate influences knowledge work is investigated on 190 participants in the region of the Province of Vojvodina (Serbia). Two standardized questionnaires were used to collect data: a knowledge management questionnaire, which included 32 questions, and a collaborative climate questionnaire of 20 questions. To test the hypothesis of the study, the technique used was descriptive statistics, confirmatory factor analysis, and structural equation modeling. The results show that only the organizational culture as a dimension of collaborative climate contributes to the explanation of all the activities of knowledge management, except the activity of leaving knowledge, which fails to achieve a statistical relationship with any dimension of collaborative climate. This study provides useful insights for practitioners wanting to improve an organization’s performance and to increase organizational sustainability and learning. It is a useful base to expand further research in a way of better understanding the impact that collaborative climate has on the implementation of knowledge management in a transition towards a knowledge economy.

On average, approximately 22 thousand tons of new lubrication oil were marketed annually in Serbia in the period 2015–2019. Less than 20% of the waste lubrication oil (WLO) generated was treated, whereas the remainder was mostly uncollected or improperly disposed of. The purpose of this study is to examine different WLO management scenarios that could be implemented in Serbia in the future and to quantify their potential environmental benefits. Different WLO treatment processes (namely the re-refining of used oil for base oil recovery, the use of WLO as a substitute to fossil fuels in cement kilns, and the combustion of WLO in waste incinerators with energy recovery) were evaluated using the life cycle assessment (LCA) and ReCiPe 2016 impact assessment methods. The LCA results obtained indicate that no single WLO treatment process consistently exerts diminished environmental impacts according to all the impact categories considered. From a human health perspective, the incineration of WLO in waste incinerators was found more favourable than the other treatment processes considered, whereas the combustion in cement kilns was the most favourable approach with regard to ecosystem protection. In terms of fossil fuel savings, re-refining technologies performed slightly better than the other processes considered. This can be accounted for by significant amounts of marketable co-products generated in the re-refining process, which can be used as a substitute to fossil-based primary products. Furthermore, a total of four possible WLO management scenarios were developed on the basis of the annual quantities of untreated WLO and a mix of treatment options. The results obtained indicate that up to 22,100 t CO₂ equivalent and 34,300 t oil equivalent could be saved annually in Serbia provided the most favourable WLO management scenario is considered.

This research investigates current preferences in wine purchase patterns and factors that affect the online purchase of wine by Generation Y and older cohorts in the Republic of Serbia. Our research utilizes descriptive statistics, chi-squared tests, the Mann–Whitney nonparametric test, and binary logistic regression. The results indicate that wine purchasing is conducted on an occasional basis—mostly monthly and weekly—with a tendency to buy wine throughout the whole year. The older cohort has a more pronounced rank, compared to Generation Y, regarding WTP for wines with a specific geographical origin and local wines. Although Generation Y and the older cohort have no habit of buying wine online, the information on geographical origin represents the most important online information related to online purchase intention. The strongest influence on online wine purchasing among members of the older cohort is a link that connects producers with consumers to allow the latter to obtain additional information and send remarks, suggestions, and/or praise, as well as a link to the winemakers’ association website, and the very significant influence of female gender. The strongest influence on online wine purchasing in Generation Y is the information on geographical origin. Female gender and income are also very significant. As wine consumption in the Republic of Serbia is gradually increasing, a growing interest in online wine purchases is expected. Our findings can provide useful information for building profiles of online wine consumers, depending on age cohort.

This paper examines the existence of the need and willingness of media companies in Serbia to organize professional training for their employees, with the aim of improving their knowledge and skills and for the sake of their career growth, analyzed in the context of business sustainability, as well as the sustainability of human resources in a very competitive media industry. The main purpose of the paper is to determine the relationship between professional training for media professionals and their career growth. It looks into the subjective assessment of the need for training, the subjective assessment of the usefulness of training, and organizational support related to training and development in order for media professionals to achieve career growth. A correlation study was conducted on a sample of 150 media professionals using three scales of a job training and job satisfaction survey questionnaire to determine the subjective assessment of the need for professional training, the subjective assessment of the usefulness of professional training and organizational support to training, while a modified organizational career growth scales questionnaire was used to determine career growth. Research results confirmed that employees believe that additional training has an impact on the development of their career, as well as that attending additional training has a positive effect on their career growth. This paper provides useful guidelines for company management regarding professional training and its implications on career growth, theoretical and practical implications, as well as suggestions for future research.

The research on Bus Fleet Management (BFM) has undergone significant changes. It is unclear whether these changes are accepted as technological change or as a paradigm shift. Perhaps unintentionally, BFM is still perceived as routing and scheduling by some, and by others as maintenance and replacement strategy. Therefore, the authors conducted a Systematic Literature Review (SLR) to overview the existing concepts and school of thoughts about how stakeholders perceive the BFM. The SLR post-study exposed that BFM should be acknowledged as a multi-realm system rather than a uniform dimension of fulfilling timely service. Nonetheless, the work encapsulates BFM evolution which shows the need for the multi-realm research abstracted as "Bus Fleet Mobility Management" and "Bus Fleet Asset Management". The difficulties of transport agencies and their ability to switch from conventional to Zero-Emission Buses (ZEBs) illustrates why we propose such an agenda, by which the research is validated through needs both in academia and in practice.

The purpose of this study was to determine the effects of an experimental treatment on morphological characteristics as well as basic and specific motor abilities of young karate trainees. 12 morphological, 12 basic motor variables and 5 specific motor variables were applied on 82 boys aged 10-12 years. There were statistically significant differences in morphological characteristics at p<.001. The greatest effects were seen for skin folds, which were significantly lower after treatment. Significant differences were also found for most motor skills at p<.001 (for 9 variables; for one at p<.05). However, no differences were determined in foot tapping and balancing on one foot on a balance beam. The results showed that quite satisfactory effects were achieved, particularly in those abilities with no genetic limitations, which can be considered a significant contribution to sport science and theory of sport and sports training.Key words: boys; differences; influence; Olympic sport; physical education. Â ---Â Cilj ovoga istraživanja bio je utvrditi utjecaj eksperimentalnoga programa vježbanja na morfološke karakteristike, bazične i specifične motoričke sposobnosti kod mladih polaznika treninga karatea. Na uzorku 82 dječaka, u dobi od 10 do 12 godina, primijenjeno je 12 morfoloških, 12 bazičnih i 5 specifičnih motoričkih testova. Utvrđeno je da postoje statistički značajne razlike (p < 0,001) u testovima za procjenu morfoloških karakteristika. Najveći učinci transformacijskoga procesa vježbanja uočavaju se na varijabli kožnih nabora koji su nakon kineziološkog tretmana bili znatno niži. Uočene su i statistički značajne (p < 0,001) razlike kod 8 testova za procjenu motoričkih sposobnosti te za jednu varijablu na nivou značajnosti p < 0,05. Međutim, nije bilo statistički značajne razlike kod testa taping nogom i ravnoteža na jednoj nozi. Rezultati ukazuju kako su postignuti sasvim zadovoljavajući učinci, posebice kod onih sposobnosti koje nisu jako genetski determitirane, što se može smatrati značajnim doprinosom znanosti o sportu i teoriji sporta te sportskoga treninga karatea.Ključne riječi: dječaci; olimpijski sport; razlike; tjelesna i zdravstvena kultura;utjecaj.
