The use of paper is widespread. It could be used in many purposes, starting from printing industry, over different type of packaging etc. At the same time significant amount of waste paper is generated. As material, paper has excellent recycling properties. Paper could be recycled several times, retaining its original quality. The main goal of this research is to present the current situation in the management of waste paper in the Republic of Serbia. It is evident that awareness of citizens is not satisfying in terms of paper disposal. This is also shown by surveys carried out in the cities Zrenjanin and Novi Sad, which can present the general situation in our country. The research presents the public opinion focused on potential causes of low recycling rate. Using STAN software and Material Flow Analysis (MFA), based on the available amount of waste paper, it is estimated which amount of paper is used as a secondary raw material, and which part of the waste paper ends on sanitary and unsanitary landfills. The results of the assessment may be the starting point for some further research. [ABSTRACT FROM AUTHOR]

To encourage proper waste management for electrical and electronic devices (e-waste), it is necessary to invest heavily in the development of recycling technologies. One way to improve the process is to automate separating the shredded parts of e-waste using a robot. This paper's literature review, utilizing the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) framework, showcases potential robotic technologies for e-waste separation. However, the intricate design of these devices can pose significant challenges in their implementation. Various legal, organizational, and sociological obstacles have left Serbia's e-waste management practice underdeveloped, resulting in an unsatisfactory recycling rate. In this paper, we examined the possibility of using robots in the precise example of recycling refrigerators in a recycling center in Eastern Serbia, concluding that such a solution would have multiple positive effects, both on the employees and the working environment, on the operations of the recycling center itself, and on increasing the e-waste recycling rate in the country.

The repository of the Faculty of Chemistry, University of Belgrade, and the Innovation Center – Cherry presents a well-organized digital library of the institution’s scientific outputs. For the purpose of this paper a research was done on the change in the number of citations contained in the repository, based on data from the external application Authors, projects, publications. The application has integrated parameters for examining the number of citations from Scopus and Web of Science databases. In this paper the change in number of citations from publications which appear in Altmetric – a platform for alternative metric were also used. Two methods of research were applied: the first method examines the change in number of citations for all deposited records of publications in the repository, and the second method enables to examine the change in number of citations on the level of all records of a specific author. The author whose publications were examined for the research via the second method was pronounced the most cited author in the yearly report for 2021 of the Faculty of Chemistry. Both methods examine three types of records with varying levels of accessibility: permanetly restricted, available after an embargo period (green open access) and permanent open access (gold open access). The metadata of all three kinds of publications recorded in the Cherry repository are accessible to the public with strict control of the librarian – repository manager. The research subject of this paper notes the difference that arises in the number of citations of individual records in September 2021 and a year later, in September 2022. The aim of the paper is to present a possible method to establish a correlation between the accessibility of publications and their citation count. There is a special regard to publications in the green open access, which form the basis for monitoring the relevance of the repository to the Faculty of Chemistry, University of Belgrade, and the Innovation Center as well as to other institutions which are parts of the established infrastructure of repositories in Serbia.

The number of published scientific paper grows rapidly each year, totaling more than 2.9 million annually. New methodologies and systems have been developed to analyze scientific production and performance indicators from large quantities of data available from the scientific databases, such as Web of Science or Scopus. In this paper, we analyzed the international scientific production and co-authorship patterns for the most productive authors from Serbia based on the obtained Web of Science dataset in the period 2006–2013. We performed bibliometric and scientometric analyses together with statistical and collaboration network analysis, to reveal the causes of extraordinary publishing performance of some authors. For such authors, we found significant inequality in distribution of papers over journals and countries of co-authors, using Gini coefficient and Lorenz curves. Most of the papers belong to multidisciplinary, interdisciplinary, and the field of applied sciences. We have discovered three specific collaboration patterns that lead to high productivity in international collaboration. First pattern corresponds to mega-authorship papers with hundreds of co-authors gathered in specific research groups. The other two collaboration patterns were found in mathematics and multidisciplinary science, mainly application of graph theory and computational methods in physical chemistry. The former pattern results in a star-shaped collaboration network with mostly individual collaborators. The latter pattern includes multiple actors with high betweenness centrality measure and identified brokerage roles. The results are compared with the later period 2014–2023, where high scientific production has been observed in some other fields, such as biology and food science and technology.

In response to the first three articles that appeared in the Agora on Kosovo, this paper argues that there is a right of unilateral secession based on the right of external self-determination. According to the authors, the latter right is applicable outside a colonial context, in limited circumstances resembling the colonial paradigm. Modern customary international law provides the legal basis for a right of “remedial secession”, an argument that is supported by relevant State and institutional practice. After having discussed the conditions of this right and its legal basis, the authors apply their findings to the Kosovo case, in order to answer the question whether the Kosovo Albanians had a right of unilateral secession under international law.

Heterozygous familial hypercholesterolaemia (FH) is among the most common genetic metabolic lipid disorders characterised by elevated low-density lipoprotein cholesterol (LDL-C) levels from birth and a significantly higher risk of developing premature atherosclerotic cardiovascular disease. The majority of the current pediatric guidelines for clinical management of children and adolescents with FH does not consider the impact of genetic variations as well as characteristics of vascular phenotype as assessed by recently developed non-invasive imaging techniques. We propose a combined integrated approach of cardiovascular (CV) risk assessment and clinical management of children with FH incorporating current risk assessment profile (LDL-C levels, traditional CV risk factors and familial history) with genetic and non-invasive vascular phenotyping. Based on the existing data on vascular phenotype status, this panel recommends that all children with FH and cIMT ≥0.5 mm should receive lipid lowering therapy irrespective of the presence of CV risk factors, family history and/or LDL-C levels Those children with FH and cIMT ≥0.4 mm should be carefully monitored to initiate lipid lowering management in the most suitable time. Likewise, all genetically confirmed children with FH and LDL-C levels ≥4.1 mmol/L (160 mg/dL), should be treated with lifestyle changes and LLT irrespective of the cIMT, presence of additional RF or family history of CHD.

This paper aims to identify, evaluate, and analyze determinants of the profitability of food enterprises from the Republic of Serbia. The paper determines the nature of the relationship between defined determinants and profitability by applying a panel regression model on a sample of 189 small, medium, and large food enterprises from Serbia in the period from 2011 to 2021. The analysis results showed that the profitability of food enterprises is positively influenced by liquidity and sales growth rate. On the other hand, the indebtedness, size, and materiality of assets have a negative impact on the profitability of food enterprises. Of all analyzed variables, only liquidity does not affect profitability at a statistically significant level. The results of the analysis should be added to the fact that smaller food enterprises, with a lower degree of indebtedness and a smaller share of fixed in total assets, achieve a higher degree of profitability.

With the increasing use of renewable energy sources and decentralized power systems, certain challenges have emerged in meeting consumers' electrical energy demands. The intermittent nature of renewable energy generation means that it cannot always align with consumers' needs, resulting in periods of excess energy production when it is not required. To bridge this gap between production and consumption, energy storage systems are necessary. This paper defines the work of an isolated microgrid, which consists of renewable sources (wind and PV) for energy production, households with electric vehicles as consumers, and a combined storage system. This storage system is made from batteries, hydrogen storage, and a control system that defines the best use of the storage. Stored energy is utilized through fuel cells to generate electricity for consumption when renewable sources cannot meet the demand. This paper presents the principles of electrolysis and models of individual elements within such a system, as well as the definition and principle of control of the system functionality based on rules and conditions. The proposed control system aims to increase the energy storage lifecycle by deciding when and how to utilize which type of storage and define a self-sufficient microgrid based on renewable sources of production. An economic analysis of the storage part of the system was carried out in which the levelized cost of energy stored and the NPC of the storage systems are calculated. A simulation of the system's operation is conducted using one-hour measurements of wind turbines, solar panels, and household consumption in Serbia. To analyze the system's behavior, a one-week time horizon is considered. [ABSTRACT FROM AUTHOR]

The paper presents a specific method of environmental impact assessment applied in Strategic Environmental Assessment (SEA) for the National Emission Reduction Plan (NERP) in the Republic of Serbia, based on air quality. The specificity of the approach is in the application of a semiquantitative method of multicriteria evaluation based on air dispersion modeling and the integration of SEA goals, indicators and criteria for assessing the impact of the NERP on the quality of air and other environmental elements in this method. When predicting changes in air quality for the planning horizon to 2028, the physical, geographical and climatic characteristics of the area were taken into account, as well as technical measures to reduce SO2 emissions, since this was the dominant pollutant from the Serbian coal-fired power plants studied by the NERP. Air pollution modeling was carried out using the AERMOD software package based on the data collected, and the quantitative results obtained were used in a multicriteria evaluation as part of the SEA. The results of the research indicated the importance of applying this approach in order to significantly increase objectivity in the SEA process, since it is an important element of decision making at the strategic level. In addition, a comparative presentation of the modeling results before and after application of the NERP was an important part of the SEA process, and it provided a clear insight into expected changes in the air quality. This is a key argument for making appropriate policy decisions on spatial, energy, environmental and socio-economic development in the Republic of Serbia, which, like other developing countries, is sluggishly following global trends in energy transition.

The largest and the deepest landslides in Serbia occurred on the right valley side of the Danube. General conclusions about landslides along the Danube were obtained on the basis of their comprehensive, detailed investigations: the Sloboda bridge in Novi Sad, the Beška bridge, the large settlement of Bocke, and the high-speed railway viaduct in Čortanovci. These areas are actually large, unstable slopes with deep and shallow landslides. Deep landslides consist of several sliding blocks with 20–40 m in depth. All these landslides were formed in clays and sands of the Pliocene age in the decayed crust of these sediments. The general conclusions about landslides presented in this paper will be of great use for the construction of new facilities in the entire unstable area along the Danube, which is about 100 km in length.

Research question: The objective of this paper is to examine the level of the development of spa tourism with a special review of the wellness tourist offer of the Republic of Serbia, and also which factors of this tourist offer we should pay special attention to and improve, to achieve the highest level of tourist loyalty. Motivation: The tourism potential of the Republic of Serbia has not been sufficiently researched and that served as a basic motivational factor. Idea: Considering the tourist potential that Serbia has and partly the work of Han et al., (2017), the fact that spa tourism is the fastest-growing sector in the entire tourism industry, and that the wellness tourism offer is a very important segment of spa tourism, there is a need to identify factors that influence the visitors' loyalty formation for such tourist destinations. As the Republic of Serbia has a lot of wellness centres, it represents a very convenient location for conducting such research. Data: This research included 298 guests of wellness centres in Vrnjačka Banja: "Solaris", "Aleksandar", "Merkur", "Zepter", "Kralj", "Slatina" and "Iwa Wellness Centre". Data collection was performed during July and August 2019. Methods: The PLS-SEM method was used in this paper to test the defined research hypotheses. Factors that contribute to loyalty and revisit for the wellness and spa tourist destination were investigated, and they were measured by the appropriate number of questions: quality of wellness and spa tourism, the value of wellness and spa services, attraction of wellness and spa tourist destination and satisfaction with wellness and spa tourist destination. All attitudes were measured using a five-point Likert scale. Results: The quality and value of wellness and spa services positively impact the affection for wellness and spa tourist destination and satisfaction with wellness and spa tourist destination, while the attraction of wellness and spa tourist destination positively affects satisfaction with wellness and spa tourist destination and tendency to revisit by tourists. The existence of a positive influence of satisfaction with wellness and spa tourist destination and the desire to revisit the tourist loyalty formation was also shown. Contribution: Improving the quality, value, and effect with the Republic of Serbia as a wellness and spa tourist destination will increase the satisfaction of visitors and their desire to revisit this tourist destination, which will lead to greater loyalty in the future. This will increase the revenue generated from this type of tourism and accelerate local and regional development. [ABSTRACT FROM AUTHOR]

Research Question: This paper recommends the method for selecting the optimal ammunition caliber for the automatic rifle that will be used to equip Serbian Army units. Motivation/idea: The selection of adequate caliber does not only represent a challenge for the decision-makers in the military, but also provides information to the industry to adjust to given requests. In the current conditions, the purpose-built industry of the Republic of Serbia is faced with two key tasks that are completely correlated: meeting the needs of the Serbian Army for quality ammunition and being competitive on the market. Accordingly, the purpose of this paper is to develop a qualitative model based on the DEX method and DEXi software applied in the selection of caliber ammunition for automatic rifles for the needs of members of the Serbian Army. This paper connects for the first time the qualitative DEX method with a product of this industry. Data / Tools: In order to meet the requirements of the multi-criteria decision-making, we developed the DEX model to be used to solve the problem of making decisions about the selection of optimal caliber for rearming the Serbian Army, as well as its cost-effectiveness. The alternatives are calibers for automatic rifles 7.62 mm and 5.56 mm that are currently in use in the Serbian Army, as well as the new 6.5 mm caliber which has been announced by the expert authorities. We defined the selection of criteria functions from technical and logistic standpoints. Using the DEX method and DEXi software enables us to obtain independent recommendations by applying different criteria. Findings: Results of this research show that the caliber is a very important component when it comes to army's armament. At the same time, this question poses a challenge for the sustainable development of the weapons industry. As the optimal caliber, among the offered, after processing the input data in the DEXi software, the authors propose a caliber of 5.56 mm. This caliber dominates in most criteria and as such, it represents the best choice. Contribution: This paper contributes to the creation of sustainable development policies on the national and regional levels and it helps the key decision-makers in the military make decisions. Results of such and similar research, and the fact that the international market has a growing need for ammunition of this caliber should be guidelines for the domestic weapons industry for future development and investment.

Background: The main goal of the paper is to review the existing state and propose a model solution for the introduction of the waste-to-energy concept in the Republic of Serbia and Bosnia and Herzegovina, as these Balkan countries are a source of high pollution due to the inefficient use of fossil fuels and the operation of coal-fired power plants. Besides, these countries have very low level of waste management, which results in the uncontrolled disposal of a large amount of waste which consists of plastic and microplastic materials which are difficult to decompose in natural ecosystems. Methods: Considering the type and objectives of the study, a mixed research method was chosen as a combination of exploratory research, descriptive research, explanatory research, and modeling. Results: The main result of the research shows the unfavorable situation in the field of waste management in the Republic of Serbia, as well as in Bosnia and Herzegovina. Both countries have adopted adequate strategies and plans, but waste management is not implemented accordingly, Nevertheless, numerous problems create considerable opportunities for improvement, especially regarding the potential for energy production from waste, which is an important approach to implementing the circular economy model. The study showed that the situation is particularly unfavorable in rural areas. Hence, the research proposes (a) a novel model for waste-to-energy governance and (b) a novel model for waste-to-energy management in rural areas. The research was done, and models were developed based on the examples of the Republic of Serbia, and Bosnia and Herzegovina. However, the results can be used in countries with a similar level of waste management and with a larger share of rural areas. Conclusions: The paper emphasizes the importance of a holistic and systemic approach to waste management, with emphasis on using waste-to-energy concept as particularly applicable in the transition to circular economy. This study proposes a model for the integration of waste management (with emphasis on plastic and microplastic) and energy efficiency, presenting a model of approach that can be used in countries that are at the beginning of introducing a circular economy.

Secondary analysis is employed to address new research questions by analysing previously collected data. This paper reports on the secondary analysis of qualitative data where the original research investigated the preschool education reform in Serbia from the perspective of Hungarian ethnic minority kindergarten pedagogues. The choice to apply a secondary analysis fulfilled the aims of (i) investigating traces of socialism in Early Childhood Education and Care (ECEC) provision in Vojvodina, a northern region of Serbia; and (ii) exploring the complexity of Christmas celebrations in nurseries. In order to address the aims, a secondary analysis of 12 semi-structured transcripts was carried out. This analysis revealed important additional findings for the original study. In light of the education reforms in Serbia we found that, first, there are strong connections between the 'socialist past' ECEC practices and what these practices may look like in the future; and, second, the traditional celebration of religious holidays outside of church organizations, such as Christmas, may change in the nurseries. This paper also offers insight regarding the importance of secondary analysis which provides an opportunity to making use of existing resources. [ABSTRACT FROM AUTHOR]

After appearing only in medical law for a long time, advance directives and other forms of voluntary measures are increasingly also being recognised as an effective protector of the right to self-determination in family law. The aim of the paper is to consider the Croatian model of advance decision making in family law, observing it in the context of European, international and comparative law. In this sense, the paper first provides an overview of relevant international and European documents, then briefly analyses different solutions to the discussion in question that exist in the national legislations of the selected European countries, namely, Germany, Slovenia, the Czech Republic, Serbia, and finally a detailed analysis of Croatian law. The paper aims to point out certain doubts and ambiguities that exist in Croatian law, give suggestions for improving the legislation, and encourage the continuation of scientific research in this legal field.

The objective of this paper is to emphasize, branding as one of the possible ways to take concrete steps towards reaffirming the local values and traditional knowledge of rural populations in Serbia. Based on information gathered in the field, as well as from existing literature sources, the main goal of this study is to promote products from the Visok microregion. Due to very alarming demographic data, this may be the last chance for revitalizing this region. In this study, we highlighted the following products: Pirot kilim (Pirot rug), Pirot/Stara Planina lamb, Pirot Kachkaval cheese, Stara Planina honey, and Stara Planina potato. Besides agriculture, micr oregion Visok also has exceptional tourist potential. The conclusion of this paper emphasizes that the only viable path to revitalization is through planned investment. Such investment would facilitate the development of local infrastructure and help restore the population, thus enabling the creation of sustainable development. [ABSTRACT FROM AUTHOR]

The paper deals with index-based crop insurance as a tool for managing flood and drought risks in agriculture. We introduce a novel model for determining premium rates in index-based crop insurance which combines the loss cost method and the average yield method. The proposed model was applied to data related to the production of selected crops in Serbia to calculate unique premium rates for index-based insurance for cereals, industrial crops and fodder plants. The paper also outlines the prerequisites for index-based crop insurance to become technically, operationally, and financially feasible in Serbia. We propose the introduction of mandatory index-based crop insurance, along with necessary legislative amendments and subsidization of insurance premiums. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to examine the influence of the most significant organizational factors on primary school achievements, with a note that the achievement of the school is expressed through the quality of outcome knowledge. The research was conducted on a sample of 460 employees, from 21 primary schools, of which 439 are professionals and 21 are principals in the South Bačka County, Republic of Serbia. The collected data were processed using the Gretl software and AMOS for modelling structural equations. More precisely, the research is based on the application of exploratory and confirmatory factor analysis. A neural network based on a standard multilayer perceptron model was used in the paper to test the validity of the obtained results of the AMOS model. The results of the research show that school management is the most important factor in school achievement and that this influence is most pronounced through teaching staff and school infrastructure. The results, also show that teachers' competencies have the strongest direct influence on the quality of outcome knowledge. The results obtained indicate that decision-makers and creators of social policies must pay special attention to the selection of school principals as well as their professional education, while school principals to the selection of teachers. Future researchers are recommended to use the Sobel test to precisely determine the indirect influences of school management on school achievement. [ABSTRACT FROM AUTHOR]

This paper focuses on the possible impact of the thermal soil regime on the occurrence of forest fires in the Zaječar administrative district in Eastern Serbia. The study uses data on soil temperature from the Republic Hydrometeorological Service of the Republic of Serbia and the ERA5-Land gridded reanalysis dataset for monthly temperature and volumetric soil water of the soil level 1 (0-7 cm), and soil level 2 (7-28 cm) with horizontal resolution of 0.1°C (approximately 12 km × 12 km) during the period of 2009-2021. Differences in soil temperature at depths of 2 cm, 5 cm, 10 cm, and 20 cm at the meteorological station in Zaječar for the periods 1961-1990 and 2009-2021 are observed. By analyzing the data on the registered number of forest fires for the period 2009-2021, pronounced oscillations in the dynamics of forest fires can be observed. The minimum number of forest fires (0) is registered in 2014, when the maximum of soil moisture in the soil levels 1 and 2 is observed. A high number of forest fires corresponds to high soil temperatures in 2012 and 2017. Soils drier and hotter than the average are registered in 47.0% of all months with the fire occurrences. About 50% of fires occurred in dry and hot soils during 2012 and 2017. This percentage was zero in 2014, when there were no fires. [ABSTRACT FROM AUTHOR]

In this paper, the genus Vitrea Fitzinger, 1833 in Serbia is reviewed. All previous literature data on this genus from Serbia are summarised and used to discuss its distribution in the country and create distribution maps, supplemented by new material collected by the authors. All Serbian species are figured. For each species, a brief description of the examined specimens, data on previous findings in Serbia, the material (including types) that were analysed, the distribution and habitats in Serbia they inhabit, as well as remarks on specific species are given. A new species, Vitrea virgo Gojšina & Dedov, sp. nov., is described from a pit on Mt. Devica in eastern Serbia. Vitrea pygmaea (O. Boettger, 1880) is reported for the first time for the territory of Serbia. As some Vitrea species have a narrow geographical range and prefer certain habitats, they are particularly vulnerable to habitat changes, which is also discussed in the paper. An identification key for all hitherto known Serbian species is given. [ABSTRACT FROM AUTHOR]

The paper argues that vaccines could be viewed as artifacts which communicate various social messages and are used as instruments for fulfilling different sociopolitical goals besides meeting public health needs. It further suggests that such social, cultural and political influences may have real effects on the choices of vaccine technologies or vaccine production, and aims to demonstrate their importance in the area which is normally seen as the domain of objective science. This is demonstrated by using the example of the locally produced oral polio vaccine (OPV) in Serbia during the socialist and post-socialist periods in the country's history. [ABSTRACT FROM AUTHOR]

The critical role of energy in contemporary life and the environmental challenges associated with its production imply the need for research and exploration of its novel resources. The present review paper emphasizes the continuous exploitation of non-renewable energy sources, suggesting the transition toward renewable energy sources, termed 'green energy', as a crucial step for sustainable development. The research methodology involves a comprehensive review of articles, statistical data analysis, and examination of databases. The main focus is biomass, a valuable resource for bioenergy and biopesticide production, highlighting not only its traditional diverse sources, such as agricultural waste and industrial residues, but also non-edible invasive alien plant species. This study explores the utilization of invasive alien species in circular economy practices, considering their role in bioenergy and biopesticide production. The potential conflict between bioproduct acquisition and food sector competition is discussed, along with the need for a shift in approaching non-edible biomass sources. The paper emphasizes the untapped potential of under-explored biomass resources and the necessity for policy alignment and public awareness. Species with a significant potential for these sustainable strategies include Acer negundo L., Ailanthus altisima (Mill.) Swingle., Amorpha fruticosa L., Elaengus angustifolia L., Falopia japonica (Houtt.) Ronse Decr., Hibiscus syriacus L., Koelreuteria paniculata Laxm., Paulownia tomentosa Siebold and Zucc., Partenocissus quenquefolia (L.) Planch., Rhus typhina L., Robinia pseudoacacia L. and Thuja orientalis L. In conclusion, the paper highlights the intertwined relationship between energy, environmental sustainability, and circular economy principles, providing insights into Serbia's efforts and potential in adopting nature-based solutions for bioenergy and biopesticides acquisition.

Different capital structures and their impact on firm performance are one of the most studied topics in the finance literature. This study is an attempt to assess the impact of financial structure on profitability of agricultural enterprises in the Republic of Serbia, with the aim of evaluating the importance and nature of the contribution of the total, short-term and long-term aspects of debt to the success of the company. The financial performance of the selected sample of 38 medium and large agricultural enterprises in the Republic of Serbia was analysed in the period from 2018 to 2021. The findings of this paper indicate that total debt and short-term debt significantly determine the return on equity, while the effect of long-term debt is insignificant. The nature of the impact of all three aspects of financial structure is negative. The inclusion of size and growth of sales in the regression models showed that only annual sales growth significantly positively determines profitability. [ABSTRACT FROM AUTHOR]

This research paper considers performance determinants at firm and industry level from the perspective of agricultural industry since this industry is recognized as one of key drivers of Serbian national economy. Sample is consisted of 115 large and medium-sized firms as they participate around 50% in total sector turnover, during years 2017 - 2021. The Generalized Method of Moments was used to analyze how firm factors (lagged profitability, leverage, labor cost, size, liquidity, sales growth) and industry factors (market share and capital intensity) affect profitability. Research results showed that profitability is strongly positively affected by its past values and stronlgy negatively affected by leverage, labours costs and industry factor capital intensity. The results suggest that internal factors are key determinants of the performance of agricultural firms rather than external factors and that leverage is the most significant determinant of profitability therefore managers should pay more attention to debt policy.

The study uses linguistic corpus tools in order to establish in what contexts the issue of migration in Europe was addressed in the Serbian press in the period 2007–2017. About 20,000 randomly chosen texts from the dailies Politika and Danas were subjected to topic modelling, collocational profiling, and also a contextual examination in the case of the paper editions. The interpretation of the data considered the effect of the medium’s ideological slant on the discourse structures used. It emerged that the selection of topics and the arrangement of texts in the liberal daily Danas corresponded to its pro-European profile. Politika, in turn, seemed to be gradually shifting towards the portrayal of Europe as being mired in crisis. In addition, the procedure used in the study enabled reflection on the usefulness of the results of topic modelling for media discourse analysis. [ABSTRACT FROM AUTHOR]

Research Question: The aim of this paper is to present the effect of corporate income tax on capital structure in the food industry of the Republic of Serbia. Motivation: Based on the empirical results of Moradi & Paulet (2018) and Kuc & Kalicanin (2021), the author's aim of the research conducted in this paper is to analyse the impact of corporate income tax on the capital structure in the Republic of Serbia as a developing country with an underdeveloped capital market and to support the results of this sporadically researched area of corporate finance in the Republic of Serbia. Idea: The author believes that by determining the optimal capital structure, it could be possible to reduce the burden of corporate income tax. Given that the food industry is one of the most significant and profitable industries in the Republic of Serbia, the results of this theoretical and empirical research would be of a great benefit to the local Tax Authority and to large taxpayers. Data: The research was conducted on a sample of 250 most active companies that operated within the food industry of the Republic of Serbia in the period from 2017 to 2019. The source of data for the purposes of this research are the official financial reports of companies registered with the Serbian Business Registers Agency. Tools: Elemental descriptive statistics techniques and panel regression analysis were applied throughout the data analysis. For the purpose of data processing the author used STATA statistical software. Findings: The results confirmed the existence of a negative and statistically significant relationship between tax savings based on depreciation costs and profitability on the one hand, and capital structure, on the other. Thus, the results indicate the need of profitable companies to use high depreciation costs to provide a reduced burden of corporate income tax with a capital structure shifted to accumulated own financial resources. In addition, the results of the regression model showed the absence of a statistically significant effect of tax savings based on interest costs on capital structure. Contribution: The contribution of this paper is reflected in additional support to existing discussions on impact of corporate income taxes on capital structure. Further, the paper contributes to business practice by determining how corporate income tax burden could be reduced by choosing optimal financial mix. [ABSTRACT FROM AUTHOR]

Sustainable housing is a worldwide challenge, while the case of Serbia could be an example of how complex the circumstances can be and how difficult it is to see the path towards sustainability. This paper sets out to answer multiple challenges; can energy-efficient, low-impact housing enter the market and respond to the needs of its population, potentially contributing to a more affordable and futureproof housing reality in Serbia? And does this demand rather different measure than the ones conventionally explored in innovative housing approaches elsewhere? To answer these questions, the paper starts from the preview of circumstances, then the methodology is proposed and explained, after which the possible building materials and technical installations for pilot multi-apartment Passive House are selected, and in the end, results are given and conclusions are drawn. Since the building is intended for a housing co-operative, both the affordability of the proposed solution and the environmental footprint has been comprehended by the methodology proposed. In the end, by carefully balancing the benefits of individual measures – favouring those that are cost-effective and discouraging the implementation of measures that are not, a viable pilot project that could step into the market-oriented society is selected.

The paper analyzes fruit and vegetable juice production sectors in Serbia and Croatia, with a special emphasis on the analysis of financial performance indicators. Cost-effectiveness, profitability and liquidity indicators over the five-year period have been calculated on the basis of financial data. The aim of the paper is to examine whether there is a statistically significant difference between these indicators in the sectors of the two countries. Having in view that previous research results indicate a lower level of technical effectiveness of Serbian agriculture compared to EU countries, the paper examines the potential of the processing sector in generating new value and the possibility of creating a new product from primary agricultural products with considerably better business results. Based on the statistically significant difference in the mean values of financial indicators, the conclusion is that this sector in Serbia is more liquid and profitable than the counterpart sector in Croatia.

This paper aims to explore the worldview of young people in Serbia (defined here as roughly those aged 18-30) who are experiencing prolonged youth due to the repercussions of critical events that shaped their formative years, from the viewpoint of one particular friendship group. By documenting the "nodal points" and rituals of a group of young people in a small Serbian city, utilizing research gathered through a variety of methods, including direct observation, ethnographic participation, and formal interviews, this paper seeks to open a window of understanding to the liminal space occupied by youth in the face of the material and economic forces shaping the sociopolitical background of their lives. This paper also aims to contextualize the current social and economic climate that young Serbians are facing. [ABSTRACT FROM AUTHOR]

The Environmental Protection Agency of the Republic of Serbia continuously monitors and collects air quality parameters at numerous measuring points throughout the country. The results revealed that the levels of air pollution recorded during the lockdown differed from those recorded during the same period the previous years. In this paper, we examined pollutant concentration trends in 2020 and a few previous years to determine the underlying causes of these trends. Pollutants are measured at five stations in Belgrade from the beginning of March to the end of July between 2015 and 2020. Because no hourly data were available, NO2, SO2, and suspended particles PM10 and PM2.5 are average daily values, whereas CO and ozone are daily 8-hour maximums. Concentrations were compared and averaged only when data for the same period over time was available, i.e. when comparing 2020 to previous years. The results were compared to the annual and daily limit values (for ozone and CO 8 hours maximum, respectively), as well as the variations in concentrations over time. The goal of calculating and displaying these values is to specifically identify a change in air pollution during the COVID-19 virus pandemic isolation period. In general, for Belgrade in 2020, NO2 concentrations are lower at four stations, PM2.5 concentrations are lower at two stations, PM10 concentrations are higher at one station and lower at another, and SO2 concentrations are higher than in previous years (2015-2019).

Research Question: This study investigates both direct and indirect effects of employee ICT skills on business e-commerce potential, evaluated through e-commerce website functionality. Motivation: The study aims at expanding the existing knowledge regarding organisational ICT implementation by investigating the relation with e-commerce potential. Idea: The main idea of the paper is to understand how e-commerce potential can be improved by developing the digital skills of employees, mainly in the context of the implementation of cloud computing, portable technologies and e-commerce outsourcing. Data: A sample of 238 businesses from Serbia was considered. Responses were gathered by the Statistical Office of the Republic of Serbia, using EUROSTAT-based questionnaire. Tools: Confirmatory factor analysis and covariancebased structural equation modelling were employed for data analysis. Baron-Kenny approach was used for assessing the mediation effects in the model. Findings: Employee ICT skills showed no direct influence, but were found to have an indirect effect on e-commerce website functionality, which is manifested through organisational implementation of cloud computing and portable technologies. Findings to a certain extent suggest that certain differences between companies from transition and developing economies exist, especially regarding cloud technology adoption. Outsourcing of certain e-commerce activities showed no link with employee ICT skills, but was identified as the most influential factor in website e-commerce facilitation. Contribution: This study contributes to ICT use and e-commerce development literature, as it is the first one to investigate the direct and indirect relation between organisational ICT implementation and website e-commerce potential.

The production of plum and cherry, as stone fruit species, occupy a significant place in the plant agricultural activity of the Republic of Serbia. In this paper, on the basis of data from selected family holdings in the southern part of Serbia, the production results and evaluation of the economic justification of these two fruit species were investigated. Data collected through a survey were used for the research, and the economic evaluation was performed using static calculative methods. The most important economic indicators determined were: cost price, net profit (average amount), accumulativeness expressed through the rate and time period of investment capital. When producing plums, the average annual financial result is from 503,490 RSD/ha to 594,340 RSD/ha. The analysis determined that by investing RSD 100/ha in production of plum, 40 RSD is accumulated, and the average annual net profit is 425,313 RSD/ha. From the average amounts of net profit, investments made in raising plum trees plantations (1,080,000 RSD/ha) can be recovered during the third year of its exploitation. Although the yield of cherry per unit area is lower compared to the yield of plum, better economic results in the amount of 535,800 RSD/ha to 682,920 RSD/ha are achieved due to a much more favorable selling price per unit measure. For every RSD 100 invested in cherry production, 48 RSD of accumulation is achieved. The average net profit amounts to 492,099 RSD/ha, and the investments made in raising plantations of cherry trees (1,020,000 RSD/ha) can be recovered in the third year of its exploitation. In recent years, cherry have been very profitable fruit species in Serbia, due to the high demand and favorable selling price. With permanent education of fruit producers, as well as with various support measures at the state and local level, it is possible to contribute to the improvement of the existing business and improve the profitability of plums and cherry production.

From a global point of view, the Republic of Serbia has favorable conditions for cattle breeding and beef production, because there are favorable soil and climatic conditions, high production of roughage and fodder, available workforce, installed capacities of meat processing industries (for the production of beef and meat products) etc. However, it is not the only, or exclusive, parameter of the development of cattle production, because there are significant differences in the racial composition and production potential of cattle in certain production districts of the Republic of Serbia. The paper shows the period of the movement of the number of cattle, as one of the potentials for the production of beef, and the heifers that provide new heads for fattening. In the observed time period from 2012 to 2022, it is in permanent decline. According to the obtained data of the calculated value of base and chain indices for the observed time period of ten years, there is no hint of stabilization of breeding and increase in the number of cattle for slaughter. The average number of cattle in the Republic of Serbia was 898 thousand head with a tendency to decrease from 2.5% to 3.0%. At the end of 2022, the estimate of slaughter outside slaughterhouses in December was reduced to 16 thousand heads, however, the number of slaughtered heads increased from May and reached its maximum in October with 20.61 thousand heads and in November when there were 26.45 thousand heads. From this data, it can be seen that the total number of heads has been decreasing since December, which means that there has been stagnation in the number of slaughtered heads. [ABSTRACT FROM AUTHOR]
