Nowadays, collaborative learning is proving to offer solutions to new inclusivity research challenges, and most importantly, can help ensure sustainable education. Collaborative learning can strengthen positive attitudes towards learning, improve performance in academic results, and enhance self-esteem, by promoting interaction and mutual support among young people. Extended reality (XR), associated with collaborative learning, offers a further advantage by facilitating deep comprehensive learning. An online survey was conducted to investigate respondents’ views on the impact and influence of virtual technologies on work, study, and social life. Respondents (n = 1032) were recruited from Serbia, Romania, and Hungary, from five public and private universities. The study reveals students’ perceptions of e-learning and XR immersion. The data were analyzed by using a combination of descriptive techniques from PSPP (GNU open source SPSS—Statistical Package for the Social Sciences, Free Software Foundation, Boston, MA, USA), and by designing a regression model to evaluate the work-life balance. This regression model shows that the work-life balance is positively influenced by the inclusion of XR facilities in the e-learning process, along with an increased level of culture and living standard. The higher living standard of a student is associated with higher digital competence and more financial resources available to invest in technology.

Green Public Procurement (GPP) became an efficient instrument to achieve the objectives of environmental policy expressed by the European Commission in its Communications. At the same time, it must be addressed by the public authorities as a complex process, in which all purchased goods and services must integrate perfectly into an entire puzzle-like system of legislation, the construction field, innovation, healthcare, food, and education. Scientific references published in the Web of Science (WoS) mainly between 2017 and 2020 were investigated, and they analyze the implications of green public procurement in various fields, as presented by scientific communities. This article brings as a novelty in this context the identification of some barriers in the adoption of these processes, so that they can be overcome. Based on good practices and international standards and trends, the article shows how aspects related to the implementation of green procurement in society can be taken into account. In the second stage, we added a case study on Romanian green agriculture and discussions regarding inter-correlation between different fields and GPP.

Nowadays, firms have to face challenging economical cirses, like the one caused by the COVID-19 pandemic, where volatility, uncertainty, complexity, and ambiguity are manifested. Strategic management is seen as one of the key approaches that firms can choose to implement sustainable smart working (on the support of Internet of Things and smart technologies) and to face global competition. In this article, as a response to the current crisis, we study the influence of Smart Working on Eco-innovation within EU 28 countries. Specifically, we evaluate the relationship between Eco-innovation index for EU 28 countries and Smart Working, by using a clustering analysis. The results show that the increased labor productivity and employees’ eco-innovation are associated, to a higher extent, with the companies agreeing to a flexible and comfortable environment. These companies agree with the introduction of special programs such as working from home. We also prove that Smart Working is implemented by innovative leaders gaining economic sustainability. This study also provides several theoretical and practical contributions. We provide (i) an overview of sustainable management, including the diverse theoretical and methodological perspectives; and (ii) the recommendation of an innovation model through the bilateral collaboration for the constructs of performant sustainable strategies.

The objective of this research is to demonstrate the importance of supply chain management strategy, logistics and marketing to overall company performance. We considered supply chain management strategy based on universality and integration, i.e., their company performance will be increased with implementing this strategy in breweries in Serbia. The strategy based on the universality and integration includes three parts: universality and integration with customers, suppliers, and in intra-organizational processes and activities. In this paper, logistics performance called fundamental item for evaluating supply chain management strategy performance. All managers in breweries in Serbia are considered as subjects of this study. A number of 110 managers are selected as sample through random sampling method. The present study carried out through the use of questionnaire and SPSS software, correlation statistics test and multiple regressions have also been used for the data analysis. The results of correlation test showed that supply chain management strategy has significant relationship with the logistics performance and company performance and has the highest relationship and correlation with the logistics performance. Due to the observance to the multiple regression results, we found that performance of the breweries feel the highest effect from marketing performance and marketing performance also feels the highest effect from the logistics performance and consequently, implementation of supply chain management strategy is obtained. So, it can be said that organizational performance is increased as a result of implementation of supply chain management strategy.

The aim of this paper is to highlight the important issues of the budget deficit and public debt and their impact on economic growth. This paper considers the twin deficit hypothesis, which argues that there is a strong correlation between the current account deficit for an economy and government budget deficits. In the last ten years, Serbia is faced with a situation of simultaneous fiscal deficit and current account deficit. However, the growth of gross domestic product and the maturity of the debt obligation indicate that the debt burden increases, the weak development of the economy and the debt, and the power of the state and threatened to open debt crisis, the emergence of foreign insolvency. To explore the effects of budget deficits and public debt in macroeconomic relations and aggregates applied the methods of descriptive statistics, and used the official data of the relevant national and international institutions. The main results of the analysis indicate a crisis of public finances, which are accumulated for many years, with a growing budget deficit and the dominant external financing of the budget deficit.

At the beginning of the paper, the question was raised as to whether the content criminal law regulation as a primary protective object can act preventively on the potential conduct of new criminal offenses against the economy and thus be a significant factor of total economic stability. In the paper, the normative method was first applied, complemented by analytical and deductive methodological approach, and basic quantitative data analysis. The primary legislative source consulted in the work is the Criminal Code. The consequences of all individual criminal offenses can very strongly affect certain aspects of economic relations. Every criminal offense has its own specific object of the act, while the passive subject is in fact the Republic of Serbia and all its citizens. With the content of criminal law, we do a lot in the field of economic stability. The state that nurtures and improves the criminal justice system is the state that holds the most dangerous crimes effectively under control, which directly affects stability and prosperity.
