The objective of this study was the analysis of materials used in five Oriental manuscripts from Bosnia and Herzegovina dating from the 15th - 19th century. The manuscripts were examined using various analytical techniques ranging from a series of preliminary tests (visual inspection, microchemical tests, thin layer chromatography (TLC), acidity status, UV fluorescence) to Fourier-transform infrared (FTIR) spectroscopy, X-ray fluorescence (XRF), optical and scanning electron microscopy (SEM-EDS). The obtained results showed that the manuscripts were made using paper, ink and pigments derived mainly from natural sources. The paper was made from either flax fibers or the combination of flax and hemp fibres and was often sized with egg white and alum to improve its quality. Both carbon black and iron-gall inks were used for the main text, whereas vermillion was chosen only for red ink. This research provides a valuable insight into the production techniques used in Oriental manuscripts from Bosnia and Herzegovina during that period. It also represents a template approach for manuscript characterisation and science-based paper conservation. [ABSTRACT FROM AUTHOR]

Winter sports are sports considered as most attractive sports all around the world. Visiting mountains gives people feeling of: relaxation, pleasure and it influences on their health and cardio vascular and respirator system. This study included sample subjects of 6 magazines, which are available on the web pages. Magazines from the period of 2009-2019 are taken into consideration i.e. magazines in the last 10 years. METHODS: Method of analysis is used for data processing. That is procedure of scientific research by breakdown of complex terms and conclusions on the simplest parts and elements. All magazines are analyzed by years and each paper is analyzed, in detail. Analysis of 6 magazines from different cities of Bosnia and Herzegovina (Sarajevo, Mostar, Travnik, Tuzla and Banja Luka) and one magazine from Croatia (Zagreb), showed that there is small number of papers on winter sports in sport scientific magazines. Most papers on winter sports, was founded in magazine Kinesiology Zagreb and magazine Sport Logia Banja Luka. CONCLUSION: Sport presents every aspect of entertainment, fun and play and physical exercise and through contest and competition asks for measurable effect of work i.e. sport result.

Research shows that there is a significant resources waste in construction, and accordingly lagging in productivity behind the productivity of the global economy and industry in particular. There is also a small number of papers and studies on this waste. On the other hand, a higher productivity level requires small waste of material, energy and other inputs. Therefore, construction companies are deciding to introduce lean as one of the leading methods of waste reduction. This paper deals with the introduction of lean in construction companies in BiH, currently at very low level. Bearing in mind that most construction companies in BiH are small, it concludes that introducing lean and thus reducing the resources waste and increasing productivity and competitiveness requires more information and particularly skills improvements.

The paper presents the chemical composition of the fruits of three apple cultivars (Jonagold Decosta, Red Idared and Gala Schnitzer Schniga) fertilized with three treatment: T1 (control-without fertilization); T2 (300 kg/ha NPK (6:18:36) + 150 kg/ha N (calcium ammonium nitrate-CAN)) and T3 (foliar nutrition-mixture organic-mineral fertilizer commercially named 'FitoFert Kristal' (0.6%) (10:40:10) + 'FitoFert Kristal' (0.6%) (20:20:20) + 'FoliFetril Ca' (0.5%) (N:Ca) in Bosnia and Herzegovina during two years (2020-2021). Significant differences of contents of soluble solids, total sugars, inverted sugars, sucrose, total phenolic content, content of flavonoids and antioxidant activity were found among cultivar/treatment combinations, cultivars, treatments and years. Differences in total acids content among treatments and years were not statistically significant, but significant differences among cultivars and cultivar/treatment combinations were found. The contents of soluble solids, total sugars and sucrose were the highest in fruits of cultivar Jonagold Decosta, while the highest contents of inverted sugars, total acids, total phenolics, flavonoids and antioxidant activity were found in fruits of Red Idared cultivar. The fertilization treatment T2 significantly influenced the content of soluble solids, total sugars, inverted sugars, total acids, total phenolic, flavonoids and antioxidant activity in the apple fruits. According to the results obtained, we can say that fertilization treatment T3 do not have much effect on bioactive ingredients, with the exception of the sucrose content. Among mineral elements, four were macroelements that were represented present in large amounts: potassium (K) (1266.15 mg kg-1 to 1652.89 mg kg-1), calcium (Ca) (122.76-474.90 mg kg-1), phosphor (P) (86.14-124.84 mg kg-1) and magnesium (Mg) (57.36-70.68 mg kg-1). On the other hand, four microelements were determined: boron (B) (1.06-14.25 mg kg-1); iron (Fe) (2.79-4.62 mg kg-1); manganese (Mn) (0.27-0.46 mg kg-1) and zinc (Zn) (0.15-0.48 mg kg-1). Results showed that contents of macroelements and microelements have been strongly affected by cultivar/treatment combinations, cultivars, treatments and years. [ABSTRACT FROM AUTHOR]

An eighteenth-century transcription of the Qur'anic text, originating from Istanbul but now housed at the Mesudija Library in Bosnia and Herzegovina, underwent a series of analyses prior to conservation. The artefact characterization included preliminary analyses accompanied by microscopy such as determination of the fiber composition, paper typology, and microchemical tests. The acidity status of the paper was established by measuring the pH, and proteins of the sizing material were confirmed by employing thin layer chromatography. Foxing stains were examined by UV fluorescence and optical microscopy. Selected pigments of the illumination, the black ink, and the gilded book cover were examined using X-ray fluorescence. The identity of pigments was confirmed by Fourier transform infrared spectroscopy. The obtained results indicate that this lavishly illuminated manuscript was created by choosing the finest and least deteriorating materials of its time including carbon-based ink, gold for illumination, lignin-free paper, and protective layers consisting of egg white, alum, and starch. Collectively, these findings provided valuable guidelines for the conservation processes of this manuscript. [ABSTRACT FROM AUTHOR]

"Mass atrocities and the police: A new history of ethnic cleansing in Bosnia and Herzegovina" edited by Christian Axboe Nielsen examines the role of the police services in the descent into violence in Bosnia. The book argues that the war in Bosnia began with the police and that understanding the issues of policing and crimes committed by the police is crucial in understanding the war and subsequent peace. The author provides detailed analysis of how politics drove ethnicity and how ethnicity drove politics, leading to the collapse of internal security. The book focuses primarily on the activities of the Bosnian Serbs and their support by the Serbian government, but also touches on the early activities of the Croatian security forces. The author highlights the close cooperation between the Bosnian Serb police and various paramilitary forces, as well as the militarization of the Bosnian Serb police and their role in committing war crimes and crimes against humanity. The book does not extensively address the actions of the Croatian and Bosniak police, but the author argues that further study is needed to provide a more nuanced comparative analysis. Overall, the book provides valuable insights into the overlooked role of the police in the violence in Bosnia. [Extracted from the article]

This paper presents a detailed model of low-frequency oscillations and their damping within the Electric Power System (EPS) of Bosnia and Herzegovina (B&H). The system is modeled using MATLAB software, analysing the steady state and dynamic responses. This research highlights the challenges and impacts of integrating renewable energy sources, such as wind farms, on grid stability and oscillation damping. The paper utilizes eigenvalue analysis to investigate the dynamic characteristics of the system, emphasizing the need for efficient damping strategies to maintain system stability. The methodology includes a comprehensive review of existing literature, the creation of a detailed EPS model of B&H, and the application of eigenvalue and oscillation amplitude analysis to determine damping ratios. The dynamic responses of hydro power plants, HPP Mostar and HPP Jablanica, to transient disturbances are analysed to validate the model and refine damping strategies. The results indicate that the B&H EPS is well-damped, with all eigenvalues possessing negative real parts, and demonstrate the system's resilience to small disturbances. The results are compared with the technical report on the integration of the wind power plant WPP Podveležje. This comparative analysis shows consistent patterns between the modeled calculations and empirical data, confirming the robustness of the EPS model. This alignment underscores the effectiveness of current damping mechanisms and provides a foundational strategy for enhancing system stability with increasing renewable energy penetration. The findings highlight the importance of developing advanced control strategies to sustain system stability as the integration of variable renewable energy sources continues to grow.

In last period many distribution system operators (DSO) invest significant amount of money in smart metering system. Those investments are in part due to regulatory obligations and in part due to needs of DSO (utilities) for knowledge about electric energy consumption. Term - electric energy consumption, refers not only on real consumption of electric energy but also on data about peak power, unbalance, voltage profiles, power losses etc. Data which DSO can obtain from smart meters depend on type of smart metering system. Further, smart meters as source of data can be implemented in transformer stations (TS) MV/LV and in LV grid at consumer level. Generally, smart meters can be placed in any node of distribution grid. As amount of smart meters is greater, the possibility of data analysis is greater. In this paper a smart metering system of J.P Elektroprivreda HZ HB d.d, Mostar, Bosnia and Herzegovina will be presented. One statistical approach for analyzing of advanced metering data of TS MV/LV will be presented. Statistical approach presented here is powerful tool for analyzing great amount of data from distribution grid in simple way. For example, transformer in TS MV/LV can be overloaded for 30%, but overload period can be for example single one-hour period in whole year. With smart meter data, false conclusions can be avoided. In concerned case, grid operation engineer will not make decision of transformer replacing. With knowledge of only max. power of transformer (without time series data), false conclusion can be adopted about transformer replacing. This can increase costs of grid operation for DSO. Smart metering can help in transformer monitoring. Voltage drop in LV buses of TS MV/LV can be 10% for example. It means that quick intervention in grid must be performed. But, period of increased voltage drop can be only single one-hour period in whole year (for example). On other side, TS MV/LV can have voltage drop of 7% for example in halfyear period. These data, obtained by smart meters, can help in issuing of priority grid investments. Main contribution of this paper is in performing of the statistical analysis of smart meter data in distribution grid and using the obtained results in maintenance/investment planning process.

In order to assess the successes and failures of Bosnia and Herzegovina's (BiH) challenging road towards a fully functional democratic state aiming at membership in the European Union (EU), this paper examines the state-building process in BiH, and the transition from the post-Dayton political development, the work of the interim, ad-hoc political institution of the Office of the High Representative (OHR) in BiH, as well as the justification - if any - of its future existence and operation. Guided by the coordination dilemma, the research question of this paper is a reflection on the challenges of self-enforcing democratic institutions and how the OHR substitutes for it. This paper claims that the original purpose of the Dayton Peace Agreement (DPA) was to create a powerful yet limited institution of the OHR, one that is to be given sufficient power to institute behaviour, but is prevented from abusing its power. However, this purpose deviated in the years that followed the signing of the DPA, creating and institution which doings resemble liberal imperialism. The hypothesis of the paper is that the OHR has been abusing its power and that it is time to close it because it is no more a substitute for the self-enforcing democratic institutions. This paper claims that the problem of political officials' lack of respect for the political and economic rights of citizens they administer, as investigated by Weingast, is one of the central features of the operation of the OHR in BiH. The novelty of the paper lies in the attempt to test if OHR could be a case that could serve as a very good field to test Weingast's model (1997). [ABSTRACT FROM AUTHOR]

This paper deals with the analysis of challenges and perspectives of the transition to electric vehicles as a sustainable solution for the transport sector in the context of global energy challenges and the need to reduce negative environmental impacts. With an emphasis on the energy situation in Bosnia and Herzegovina, the paper explores the possibilities of switching to electric vehicles (EVs) and analyses the effects of energy sources on CO2 emissions. The paper highlights the motivation to switch to EVs, driven by the need to reduce greenhouse gas emissions and rely on renewable energy sources. After analysing relevant studies, it is concluded that smaller and lighter electric vehicles have lower CO2 emissions and that the participation of renewable sources in electricity production reduces these emissions. The conducted analysis of the vehicle fleet specifies that the CO2 emissions of electric vehicles are not zero and that they depend on the source of electricity. Furthermore, other factors, such as the production of batteries, also play an important role in the overall environmental impact. Although the motivation to switch to electric vehicles is emphasized to reduce greenhouse gas emissions and use renewable energy sources, it has been shown that the CO2 emissions of electric vehicles (EVs) are not zero and significantly depend on the energy sources. Calculations performed on the vehicle fleet of the Federation of Bosnia and Herzegovina for the year 2021, using Copert as the tool, showed that vehicles driven by fossil fuels emit about 1.6 million tonnes of CO2. In comparison, if all vehicles were replaced with electrical ones, the CO2 emissions would be about 1.15 million tonnes. As for the required electricity to power EVs, it is calculated that the required amount would be about 1,539 GWh per year. This paper acknowledges the presence of emissions associated with battery production, storage, and disposal, as well as vehicles themselves. However, it does not delve into this issue in detail. Future research will aim to address this matter more thoroughly. [ABSTRACT FROM AUTHOR]

The article discusses the establishment of safe areas like Srebrenica on the former Yugoslavia by the United Nations (UN) as a peacekeeping initiative. It is stated that this required the deployment of UN protection forces, but that these were unable to resist nationalist states like Bosnia, who forcibly occupied the safe areas which resulted in casualties. The long-term implications in the breaking up of Yugoslavia should reportedly have been fully understood before it was allowed.

The author examines the lessons learned from the war in Bosnia in the 1990s. He states that the U.S. did not want to interfere in the genocide committed by the Serbs, even if they had the air power to do so, because of a pro-Serb bias by the Europeans, and were content to let them handle the situation. They reportedly only intervened when there was increased brutality in Kosovo. The author stresses that the genocide could have been reduced if it was recognized earlier by more people.

The demand for hydropower production, as a prominent sustainable development strategy, has created a boom in the number of planned hydropower projects, especially small ones. These projects are mainly located in post-socialist transition and developing countries. However, emerging evidence suggests that most of the projects remain on paper. One reason for this is prevalent corruption. In the literature, corruption has been identified in megaprojects but a significant number of hydropower projects are smaller in size. This leaves a literature gap and a subsequent lack of understanding regarding corruption and its potential connection to the absence of hydropower construction. We argue that it also creates a 'safe space' for corrupt actors who use the sector for personal gain. In this paper, we address this nexus of unfinished hydropower projects, sustainable development in transition countries, corruption, and lack of scholarly attention by presenting empirical evidence from Bosnia and Herzegovina. We highlight that sustainability goals associated with hydropower might be distorted, especially in transition countries as they are intermingled with hydropower projects that are embedded in complex bureaucratic structures. We conclude that focusing on the sector might improve its management, thus contributing to sustainable development, and also help to decrease the corruption risk. • Small hydropower projects have an increased risk of corruption. • Overlooking small projects create a "safe space" for corrupt actors. • Administrative complicatedness is one key factor behind corruption in the hydropower sector.

The aim of this paper is to analyze the role of former Arizona senator Dennis DeConcini during the Bosnian War. DeConcini, along with other congressional Bosnia hawks, supported the newly independent country in its self-defense during the 1992–1995 war. DeConcini's activism was mainly through the U.S. Helsinki Commission but he also undertook a number of steps with a view to legislative American foreign policy towards Bosnia in the early 1990s. Based on the congressional archive and DeConcini's papers at the University of Arizona, this article will piece together the story of how an Arizona senator became a champion of Bosnia on Capitol Hill.

In times when AI's development and research is moving at an unprecedented speed, this paper explores its role in retail banking. The results presented are part of a wider research of market readiness and AI acceptance, especially in developing economies. The research was conducted in Bosnia and Herzegovina (B&H). The quantitative portion consisted of a survey completed by 671 respondents. This paper focuses on the influence of social factors (perceived humanness, perceived social interactivity, and perceived social presence) on the attitudes towards – and subsequently acceptance of - AI-based services. Chatbots, specifically ChatGPT-4, were the technology the research focused on. The results indicate that perceived humanness and perceived social interactivity have a positive effect on attitudes – and acceptance – of AI-based services. This research could not prove that there is a positive relationship between social presence and attitudes towards AI-based services. The positive relationship between attitude and acceptance was proven as well. [ABSTRACT FROM AUTHOR]

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.

The aim of this paper is to analyze the relationship between gender, age, education, and thermal satisfaction of employees and users in public buildings, such as schools, public administration, and clinics. The study uses data collected from a randomized stratified sample from Bosnia and Herzegovina. The primary variable of interest is a dummy variable indicating whether individuals are satisfied with the heating of the rooms. Our results revealed that gender and education level might be significant factors. However, when controlling for the type of object, the observed differences were no longer present. Furthermore, our findings show that the results do not differ significantly when the dependent satisfaction variable is measured as binary (dummy) or on a five-point Likert scale. Logistic regression provides an intuitive interpretation in terms of odds. Our study also indicates that age may be a critical predictor in the evaluation of indoor temperature, with older participants reporting the rooms in institutions to be warmer than the younger ones. The outcomes of this research could be valuable in developing policies aimed at improving energy efficiency of buildings. Understanding optimal thermal satisfaction could have significant implications for thermal energy consumption, particularly in the context of how individual characteristics, such as gender, age, and education level, might contribute to the reduction of energy consumption. By addressing the demand side of the energy consumption equilibrium, we might contribute to the better use of existing energy sources. The findings of this paper could also offer useful guidelines when designing more complex studies, especially regarding the debate if the use of a Likert scale is appropriate. [ABSTRACT FROM AUTHOR]

The problem of the unsettled land registry state of real estate generated the appearance of new problems, as such but also of some other nature, whereby some of them, and due to the sensitivity of the question, covered by their reach, at the level of the most complex issues in the legal system of Bosnia and Herzegovina. Under the spotlight of such problems, the paper points to possible directions reforms in the field of public real estate records and real estate rights. In order to choose the appropriate recording model, the most significant reform solutions are also presented in the paper, contained in the provisions of the new entity laws on land registers, i.e. of the law on real rights. With the same goal, the paper points out the importance of following rich legal traditions in the matter of establishing rights to real estate. In this respect, special attention is dedicated to the re-updated system of unique real estate records, as a kind of expression of completely different aspirations in this area.

This paper takes stock of the literature on the monetary transmission mechanism in currency boards and analyzes the process of monetary transmission in Bosnia and Herzegovina. The transmission of monetary signals through the economy is based on the automatic adjustment mechanism of the currency board. Three channels of monetary transmission are discussed in this paper: the interest rate channel, the narrow credit channel, and the exchange rate channel. The empirical analysis shows how exogenous monetary shocks are transmitted through different channels and how long it takes for the automatic adjustment mechanism to restore equilibrium in the economy.

One of the industries that was among the most disrupted by the Covid-19 pandemic was the tourism industry. Hotel owners and managers needed guidelines on how to combat the "new normal" and enable the sustainable economic operation of the hotels they managed. This paper addresses the problem of identifying performance management (PM) indicators hotel managers turned to during the pandemic and the factors which motivated them to do so. Managers of hotels in winter destinations in Serbia and Bosnia and Herzegovina were surveyed on the performance measures they implemented in the hotels they managed. The results of the research show that in the era of the Covid-19 pandemic, hotel managers relied on both organisational and operational measures but found operational indicators more useful. The characteristics of managers, such as business position in the hotel, age, level of education and level of work experience, are related to the choice of indicators and levels of their implementation. Also, the hotel's characteristics, such as size, revenue, and growth rate, proved to have an impact on the level of PM indicators measured. In times of crises, such as pandemics, organisational PM indicators that rely mainly on financial results are not as useful as operational ones. The reliance on operational measures of indicators increased the resilience of hotels. [ABSTRACT FROM AUTHOR]

Context under which it was convened Dayton Peace Conference it was very complex. Among the factors that determined the success of the peace talks were also the decisions on nomination of the delegates and on the framework of negotiations. The first one had to do with the format of the negotiation delegations and the second one with the platforms for negotiations. Both issues were interlinked and demonstrated whether parties in war seriously and constructively were approaching to the idea for peace conference. In Dayton, the interests of the Bosnian state and society, of the Bosnian Serbs and Bosnian Croats were represented by the Presidents of Bosnia and Herzegovina, Serbia and Croatia. That it was an indication that all parties in war gave priority to the dialogue even though the questions on what level must be representation in the peace conference and what mandate the appointed delegates must have very often constituted a challenge in itself during the prenegotiation period. The purpose of this paper it was to understand the political representation in the Dayton Peace Conference by analyzing the format of the negotiation delegations and the frameworks of the negotiations. For that reason, in desk research it was conducted where documents from relevant national and international institutions were analyzed. Interpretation of data it is based on the Berridge's analytical construct regarding the phases of negotiations. [ABSTRACT FROM AUTHOR]

Delay in data transmission is one of the key performance indicators (KPIs) of a network. The planning and design value of delay in network management is of crucial importance for the optimal allocation of network resources and their performance focuses. To create optimal solutions, predictive models, which are currently most often based on machine learning (ML), are used. This paper aims to investigate the training, testing and selection of the best predictive delay model for a VoIP service in a Long Term Evolution (LTE) network using three ML techniques: Multilayer Perceptron (MLP), Support Vector Machines (SVM) and k-Nearest Neighbors (k-NN). The space of model input variables is optimized by dimensionality reduction techniques: RReliefF algorithm, Backward selection via the recursive feature elimination algorithm and the Pareto 80/20 rule. A three-segment road in the geo-space between the cities of Banja Luka (BL) and Doboj (Db) in the Republic of Srpska (RS), Bosnia and Herzegovina (BiH), covered by the cellular network (LTE) of the M:tel BL operator was chosen for the case study. The results show that the k-NN model has been selected as the best solution in all three optimization approaches. For the RReliefF optimization algorithm, the best model has six inputs and the minimum relative error (RE) RE = 0.109. For the Backward selection via the recursive feature elimination algorithm, the best model has four inputs and RE = 0.041. Finally, for the Pareto 80/20 rule, the best model has 11 inputs and RE = 0.049. The comparative analysis of the results concludes that, according to observed criteria for the selection of the final model, the best solution is an approach to optimizing the number of predictors based on the Backward selection via the recursive feature elimination algorithm.

The aim of this paper is considering a brief historical perspective and overview of recent ideas and directions in electrochemistry in Bosnia and Herzegovina. Since the 1950s, dozens of researchers worked and are still working on the study of electrochemistry. The research evolved from polarography in the beginning to electrochemical deposition and/or dissolution of metals, alloys, polymers, nanocomposites and deposition of metal powders, corrosion mechanisms and corrosion protection, different catalysts and energy storage and conversion. Since the electrochemical and chemical industry was developed on the territory of today's Bosnia and Herzegovina in the period from 1950 to the 1980s, researchers and professors were focused on the problems and challenges in the industry, not on publications. The industry was destroyed after the breakup of Yugoslavia, and names of the important researchers are very difficult to find today. That is why only a few individuals can be found on scientific databases in this period. The important validations of electrochemistry schools in Bosnia and Herzegovina are former students who are successful people in the industry or academia worldwide. [ABSTRACT FROM AUTHOR]

This paper studies the extent individuals are willing to undertake energy efficiency measures, with evidence coming from a developing country (Bosnia and Herzegovina). The goal of this paper is to analyze energy-savings behaviors, aiming to understand what is typically meant under the term energy efficiency, who is more likely to know the meaning, and the extent individuals are willing to undertake some energy efficiency measures. The sample size used in this paper is a random stratified sample of 1,415 individuals coming from various backgrounds. Our logistic regression models found no statistically significant predictor across all ten measures used in the study. However, past experience, age, and being married are relatively common across these ten energy-saving behaviors. These results might be beneficial in defining policies in order to promote energy-saving behaviors. [ABSTRACT FROM AUTHOR]

Aggression on Bosnia and Herzegovina started in 1992 and lasted until 1995, where Serbian and Croatian aggressors had an objective of dividing Bosnia and Herzegovina into geographical parts which would result in strengthening territorial capacities of the Republic of Croatia and the Republic of Serbia. Aggression on Ukraine started in 2022 when Russia launched a large-scale invasion by Russian president Putin's decision to authorize the so called special military operations in Ukraine. The similarities between these two wars are the invasion of a neighboring country with the aim of territorial annexation from a smaller country and the path of those smaller, invaded countries, towards NATO and the European Union. This paper will analyze the similarities between mentioned aggressions and how it affects the NATO and EU membership in detail. Additionally, the paper will elaborate the impact of the international community in these events. [ABSTRACT FROM AUTHOR]

Two phenomena have been present in multiethnic/multinational Bosnia and Herzegovina since its independence from SFR Yugoslavia: massive depopulation and strong nationalism(s). Although nationalism influences which nation/ethnic group should produce and how, the links connecting these nationalistic ideologies and pronatalist population policies in the country/entity have been, almost paradoxically, left on the margins of the previous studies. This paper asks to what extent nationalist ideologies are present in the pronatalist population policy discourse in the Serb-dominated entity Republic of Srpska and what nationalism it is. After developing Spectrum of Nationalism(s), a framework underlined by Siniša Malešević's views on nationalism and ethnicity as ideologies, the paper provides an overview of Bosnia's demographic processes and brief insights into Republic of Srpska pronatalist policies through a semi-structured literature review. Keeping in mind that media profoundly influences public opinion, discursively moulding policy debates, two most recent cases of pronatalist campaigns and programs in the Republic of Srpska: Let Our Children Be Born and National Programme of Demographic Revival, are analysed via critical discourse analysis (CDA). Selected media articles predominantly cover the period from 2018 onwards, concentrating on the commentaries of the ruling SNSD political nomenklatura. The analysis displays the powerful influence of nationalism on the discourse on population policies. However, on the spectrum of nationalism(s), civic nationalism seems only to be pro forma defined, while in RS's reality, the abovementioned path has continued toward an ethnonationalism direction.

In studying individual consumption behavior, an important issue is the analysis of the relation between commodity expenditure and income. The subject of this paper is the analysis of clothing, footwear and housing consumption of households in Bosnia and Herzegovina. The aim of this paper is to quantify the impact of income on household expenditure for clothing, footwear and housing, with a focus on examining the validity of Second Engel's law in Bosnia and Herzegovina. Empirical research is based on the econometric modeling of Engel curves applying single equation modeling, using microdata from the Household Budget Surveys in Bosnia and Herzegovina, which are available for four years (2004, 2007, 2011, 2015). The surveys were carried out using the uniform methodology developed by the Statistical Office of the European Union (EUROSTAT). In order to achieve the research objective, six functional forms of Engel curves have been formulated and estimated. The intensity of the impact of income on relative changes in consumption was measured using income elasticities. Based on the estimated parameters and income elasticities derived from them, the hypothesis of unit elasticity of demand for the mentioned product groups in relation to household income was tested. Empirically estimated values of elasticities imply that the validity of the Second Engel's law in Bosnia and Herzegovina was partially confirmed: while clothing and footwear expenditures became elastic over time, expenditures for housing are inelastic in observed years. By comparing the estimated elasticities for different years in which the survey was conducted, it was revealed whether there were significant changes in the preferences of households in Bosnia and Herzegovina in the observed period.

This paper seeks to examine the determinants of the profitability of the B&H banking sector, using an empirical framework that incorporates the traditional SCP - structure conduct-performance and ESX efficiency hypothesis. The main goal of this paper is to measure the level of concentration and investigate how concentration and other determinants influence the profitability of the banking sector in Bosnia and Herzegovina for the period from 2008 to 2017. We also tried to determine whether the profitability of the banking sector is more contributed by concentration, i.e. enlargement of the banking market (SCP) rather than increased efficiency of banking organization (ESX). For this purpose, we use a sample of 26 banks from B&H, and our empirical research is based on panel data analysis. The performance of the banking sector is measured by the conventional return on assets (ROA). Besides concentration as a main industry-specific factor, profitability determinants include bank-specific and macroeconomic profitability factors. Obtained results reveal that concentration has positive impacts on B&H banking profitability. But when we talk about competing concentration hypotheses, the paper results here generally support the ESX efficiency hypothesis rather than the traditional SCP approach. It was confirmed that credit risk, deposit risk and cost to income ratio from bank-specific variables, and GDP growth rate from macroeconomic variables have a statistically significant influence on banking performance.

The paper investigates multidisciplinary factors influencing the quality of experience (QoE) of service users of telecommunication provider as an open-structured stock-company of people who are creators of services and applications and/or proactive service users. The quality of user experience QoE is created and improved over time under multifactorial influences. The aim of this paper is to analyze legal-regulatory, socio-contextual, technological-process and stock-company,factors as input independent variables and subjective-user factors as transition variables of influence on motivation, behavior and user satisfaction in the Model of influences factors (MIF). The output from MIF is dependent variable QoE. MIF was created on a perceptual and reference path with interactively related factors of all influences on QoE through subjective-user assessment. The quality of MIF was verified by statistical significance analysis among variables of paired factors influencing QoE using SPSS technology, regression analysis, and the Boosted Desedions Tree technique of machine learning method.
