Transitional Justice in Albania, Kosovo, and North Macedonia in a Comparative Framework

This thesis aims to enhance transitional justice studies with a focus on the Balkan peninsula, by providing a comparative analysis of the extent of transitional justice mechanisms in Albania, Kosovo, and North Macedonia. With the fall of military dictatorships in Latin America in the 1980s, the breakup of the Soviet Union, and the emergence of new states in the 1990s, the concept of Transitional Justice (TJ) saw a significant rise in the late 1980s and early 1990s. This was further propelled by the fall of the Berlin Wall (1989), the prolonged breakup of the Socialist Federal Republic of Yugoslavia (1992) as well as the fall of the communist dictatorship in Albania (1990). The emergence of new states and the state-building processes that followed the political and social changes also brought new challenges and conflicts, although they marked the end of significantly repressive political regimes. Considering that the implementation of TJ has undergone several changes over time and is dependent on the different settings in which it was employed, it is necessary to conduct extensive comparative research to determine the extent to which TJ differs in post-communist and post-conflict nations. The study has developed three main hypotheses: (1) The limited achievement of lustration law in Albania has conditioned the current status of transitional justice; (2) The state-building process has contributed to the evolution of Transitional Justice in Kosovo; (3) The power-sharing process as a TJ pillar in North Macedonia has fueled TJ in the country. By utilizing a mixed methods approach, data was collected through elite interviews, conducted in the three countries with 44 representatives from academia, politics, media, and civil society. To conclude, two hypotheses are fully upheld in terms of the limited achievement of lustration law and its implications with the current status of transitional justice in Albania; and the contribution of state-building in Kosovo to the evolution of transitional justice. The third hypothesis related to the power-sharing process in North Macedonia as a fueling mechanism for the evolution of transitional justice is partially upheld.    Received: 13 February 2024 / Accepted: 30 April 2024 / Published: 5 May 2024

Energy efficiency as a driver of the circular economy and carbon neutrality in selected countries of Southern Europe: a soft computing approach

BackgroundThe main goal of the paper is to define the level of energy efficiency in the economies of selected countries in the Balkan region that have opted for the EU Green Deal, a circular economy, and a transition to carbon neutrality. Energy efficiency, as a determinant of carbon neutrality, was selected as an indicator for analysis because it records particularly unfavorable indicators in the region under observation. The research was carried out on a sample of seven Balkan countries and their surrounding areas. An initial qualitative analysis was followed by a quantitative analysis based on a combination of statistical methods and soft computing. Six indicators were selected for the analysis covering a period of 30 years (1990–2020).ResultsA significant obstacle to the green transition and the region’s transition to a circular economy and carbon neutrality is energy efficiency and energy related pollution—the reliance of most countries on coal-fired thermal power plants for electricity generation. The research results showed the following: (a) the degree of economic development and membership in the European Union are not significantly related to the level of energy efficiency; (b) most of the sampled countries are in the initial stages of introducing activities to achieve carbon neutrality; and (c) only Slovenia has documented consistent indicators and evident advancements in its efforts to achieve carbon neutrality. Based on the research findings, proposals for improvements were made in the direction of policymaking and in a methodological sense.ConclusionsThe implementation of circularity and carbon neutrality as a long-term goal of the European Union is not necessarily related to the level of economic development, nor can its trajectory be exclusively ascertained by means of data processing and monitoring. A more precise understanding of a carbon-neutral future can be achieved through the incorporation of qualitative data to a greater extent, a realistic evaluation of historical facts and their repercussions, as well as projections of the effects that reality and global developments after 2022 will have on each country.

Tax Debts Pose a Significant Challenge for Tax Institutions

In 2020, the Tax Administration of Kosovo implemented a tax debt collection reform with three main objectives. 1) Consolidation of personnel from 10 regional offices into a centralized facility; 2) Equitable allocation of work responsibilities; 3) Enhancement of debt collection efficiency. During the period from 2020 to 2022, the implementation of the reform resulted in a substantial improvement in debt collection efficiency, exceeding 100% compared to the pre-reform years. Currently, tax officers handle debt collection cases with well-defined responsibilities and tasks, and the distribution of duty is more fair. This study investigates the involvement of top management and staff in the development and reform of the Kosovo Tax Administration's debt collection function. It also compares its participation with that of other Balkan countries. Tax authorities in developed nations have constructed their tax systems around the concepts of taxpayer self-assessment and voluntary tax compliance. Consequently, each tax revenue agency must establish an environment that facilitates taxpayers in declaring and remitting taxes while also implementing measures to combat informal economic activities and promote legitimate business operations. These efforts are crucial for achieving optimal levels of voluntary compliance and fostering public confidence in the tax administration. 

Skull asymmetry in various sheep breeds: Directional asymmetry and fluctuating asymmetry.

Sheep (Ovis aries) play an important role in the economy of Turkey and the Balkan Peninsula due to their use in farming. As a domesticated species, sheep's morphometric and morphological diversity is likely determined by selective breeding practices rather than geographic distribution. This study aimed to analyse four different sheep breed skulls and reveal skull asymmetry using geometric morphometric methods. For this purpose, 2D images of 52 sheep skulls from different breeds were analysed from the dorsal view of the skull, using 28 landmarks. In the comparison of sheep skulls from the dorsal view, the first principal components for directional asymmetry (DA) and fluctuating asymmetry (FA) were 32.98% and 39.62% of the total variation, respectively. Sharri and Ivesi (Awassi) sheep breeds had the broadest distribution of skull shapes among the breeds, while Lara e Polisit was the most conservative breed. DA was used as a measure of biomechanical constraints, and FA was used as an indicator of environmental stress. Consistent with DA, both differences in centroid size and shape between breeds were statistically significant. No differences between males and females related to asymmetry were revealed. Ivesi sheep revealed the highest fluctuating asymmetry. Geometric morphometric methods proved to be a useful tool for distinguishing differences in the shape of the skull of different sheep breeds and also can be useful for taxonomic purposes.

EU Membership of Western Balkan Countries and Digital Citizenship Practices

Following the end of the Cold War, the European Union's interest in the Western Balkans intensified, driven by geopolitical and geostrategic considerations. Moreover, the region holds significance as a transit route for energy lines supplying EU member states. Encompassing a diverse geographical expanse, the Western Balkans includes Croatia, Bosnia and Herzegovina, Montenegro, Bulgaria, Albania, Kosovo, Serbia, North Macedonia, Romania, Greece, and Slovenia. While the EU’s perspectives on the Balkan countries, situated in a geopolitically crucial position, became clearer following the Thessaloniki Summit 2003, they are currently grappling with various challenges. Within the EU, enlargement fatigue has emerged following the enlargements in 2007 and 2013. Concurrently, economic and political crises within the union have prompted restructuring efforts. These reforms, encompassing areas such as the “Rule of Law”, “Functioning Market Economy” and “Democratization and Transparency of Public Administration”, have become imperative amid the evolving global order and globalization trends. Consequently, reforms in digital citizenship have also become inevitable. This study examines the EU membership and digital citizenship practices of the Western Balkan countries.

Динамика на някои биохимични показатели при две местни породи овце в зависимост от сезона, надморската височина и наличието на паразити

The aim of the present study is to evaluate the values of some enzymes and metabolites - ALT, AST, ALP, serum iron and glucose of two herds of Bulgarian native sheep breeds raised at different altitudes, depending on the season, their body condition score (BCS) and the presence of gastrointestinal parasites. The research was conducted with 20 animals each in farms in the village of Mirkovo (715 m above sea level) with Sofia (Elinpelin) sheep breed and in the village of Gubesh (1040 m above sea level) with Central Balkan sheep breed. Body condition assessment was performed during sampling by one individual using an adapted system. Fresh faeces (total sample) were also collected for parasitological tests (coproovoscopy and coprolarvoscopy). Analysis of biochemical parameters was performed in extracted blood plasma with a BTS-350 semi-automatic biochemical analyzer. AST and glucose levels were normal, ALP and Fe were lower in both seasons, and ALT was higher than reference values limits only in summer for both breeds. There were significant differences between the two breeds in summer for BCS, ALT and glucose (p<0.001, p<0.05 and p<0.01 respectively), in winter - only for Fe (p<0.001) and in both seasons for HCT (p<0.001 and p<0.01 respectively), AST (p<0.001 and p<0.05 respectively) and ALP (p<0.001 each). Regarding the activity of AST, there are no significant differences between the two seasons and in both breeds, however, there are such differences only in Central Balkan sheep for BCS and Fe (respectively p<0.01 and p<0.001), and in both breeds together with different degrees of freedom - for all other indicators (HCT, ALT, ALP and glucose).

Genetic diversity of European tree frogs (Hyla arborea group): A systematic review

Amphibian populations are increasingly threatened by global change and the study of their genetic diversity is a major conservation priority. Western palearctic tree frog species of the Hyla arborea group are commonly distributed across Europe and the Middle East and many have declining populations. We performed a PRISMA systematic review to gain insight into the genetic diversity of H. arborea group. Sixteen published studies were included in the final qualitative analysis. While the genetic diversity of H. arborea group species was widely variable, it could often be explained by phylogeographic history. Populations in Western and Northern Europe had lower genetic diversity, with some populations also affected by habitat fragmentation. However, important regions of high genetic diversity were found in the Balkan peninsula for H. arborea sensu stricto and around the Black Sea for H. orientalis. Genetic diversity of H. molleri, H. savignyi, H. meridionalis, H. felixarabica, H. intermedia, H. sarda has been investigated only across extensive phylogeographical studies, while data regarding their genetic diversity at the local level are missing. Through our review, we identify knowledge gaps about the genetic diversity of the H. arborea group that require further investigation, of and illustrate how filling these gaps might translate into future conservation efforts.

A collaborative framework for cross-border disaster management in the Balkans

Disasters, marked by their sudden and profound impacts on human life, property, and the environment, necessitate a comprehensive management approach. This approach comprises mitigation, preparedness, response, and recovery phases, involving the engagement of various stakeholders (state/government, first responders' agencies, humanitarian organisations, emergency management research institutes). Preparedness, in particular, is essential to ensure an effective response to disasters. This research explored disaster management, with a specific focus on cross-border disasters within the Balkan region. Cross-border disasters, which extend beyond international borders and impact multiple countries and communities, present distinctive challenges due to the need for coordination and cooperation between diverse national governments and organisations. The research's exploration concentrated on the dimension of emergency preparedness management in the context of cross-border disasters in the Balkans, with a specific emphasis on the strategic preparedness phase of cross-border emergency management. This endeavor marked the pioneering attempt to provide a holistic and integrated approach to a joint cross-border preparedness disaster management framework for the Balkan region. The developed cross-border framework represents the final elements that needed to be present for all the Balkan countries when dealing together with cross-border disasters. It stems from the unanimous agreement, through the implemented Delphi study, of all the representative emergency management groups of experts from the participating countries. The outcomes serve as the foundation through the framework and hold the potential to lay the groundwork for the establishment of the first Balkan Civil Protection Observatory, providing support to the Balkan nations in civil protection and disaster management.

A Comparison between Bulgarian Tanacetum parthenium Essential Oil from Two Different Locations

Tanacetum parthenium L. (Asteraceae) is a perennial herbaceous plant with a long-standing historical use in traditional medicine. Recently Tanacetum parthenium L. essential oil has been associated with a promising potential for future applications in the pharmaceutical industry, in the cosmetics industry, and in agriculture. Investigations on the essential oil (EO) have indicated antimicrobial, antioxidant, and repellent activity. The present study aimed to evaluate the chemical composition of Bulgarian T. parthenium essential oil from two different regions, to compare the results to those reported previously in the literature, and to point out some of its future applications. The essential oils of the air-dried flowering aerial parts were obtained by hydrodistillation using a Clevenger-type apparatus. The chemical composition was evaluated using gas chromatography with mass spectrometry (GC-MS). It was established that the oxygenated monoterpenes were the predominant terpene class, followed by the monoterpene hydrocarbons. Significant qualitative and quantitative differences between both samples were revealed. Camphor (50.90%), camphene (16.12%), and bornyl acetate (6.05%) were the major constituents in the feverfew EO from the western Rhodope Mountains, while in the EO from the central Balkan mountains camphor (45.54%), trans-chrysanthenyl acetate (13.87%), and camphene (13.03%) were the most abundant components.

Morpho-Anatomical Characteristics and Volatile Profiles of Pinus nigra J.F.Arnold from the Balkan Peninsula and Southern Carpathians

This is the first report on morpho-anatomical and phytochemical differentiation of 19 native populations representing different Pinus nigra J.F.Arnold subspecies (banatica (Borbás) Novák, dalmatica (Vis.) Franco, nigra, and pallasiana (Lamb.) Holmboe) in the Balkans and Southern Carpathians. The 9 morpho-anatomical characteristics and 10 headspace volatiles of needles were analyzed with multivariate statistical analyses. The combination of results from all multivariate analyses with both types of markers revealed that P. nigra is differentiated into three groups within the studied area (the Dalmatian coast, Greece, and the rest of the Balkans with the Southern Carpathians). The first group included the population from an island in Dalmatia that corresponds to P. nigra subsp. dalmatica. The third group consisted of populations from continental Croatia, Bosnia and Herzegovina, Serbia, Romania, and Bulgaria, which corresponds to P. nigra subsp. nigra. In light of the recent molecular data that indicated that the Greek populations (the second group) represent a distinct genetic lineage of P. nigra placed between the populations from the principal area (P. nigra subsp. nigra) and Turkey (P. nigra subsp. pallasiana), one can speculate that there is one more subspecies of P. nigra in this region that corresponds to populations from Greece. Extending our analyses to Asia Minor and Crimea could bring additional results that would be valuable for clarifying the intriguing issue of the diversification of P. nigra in the eastern part of its range.

Navigating brain drain in the Western Balkans

This article analyses the European Commission’s attitude vis-à-vis labour migration and brain drain in the Western Balkans. It uses Croatia’s post–EU accession experience as a focal point. Grappling with elevated migration rates and a decline in natality, the Western Balkan countries are an interesting region in terms of demographic change. Examining how much attention the Commission pays to brain drain, the article notes an increase since 2019; yet this focus appears disproportionately limited considering the potential repercussions for economic growth and social welfare in the countries experiencing it. The Commission’s predominantly negative view of brain drain emphasises that it is the nations affected that are responsible for avoiding it, thereby confirming that it is caused by a skills mismatch. The article recommends integrating brain-drain prevention measures into the enlargement process, and encourages the Commission to improve its focus on the matter in its annual candidate and potential candidate country progress reports.

Causality between Greenfield Investments, Regulatory Quality, and Economic growth: Is the Western Balkans different?

The study aims to examine the causality link between Greenfield Investments, Regulatory Quality, and Economic Growth by using seven Western Balkan countries between 2003 and 2022. Johansen cointegration tests, the VECM model, and multiple empirical unit root tests are the foundation of the empirical analysis. The study's findings indicate that, in the short run, GFI-led growth in Albania and North Macedonia is supported. In the long run, the analysis backs the growth driven by GFI in Serbia and Montenegro and the growth driven by regulatory quality in Albania, Bosnia and Herzegovina, North Macedonia, Serbia, Montenegro, and Bulgaria. The findings support the growth driven by regulatory quality in most Western Balkan countries, reassuring national policymakers that encouraging improvements in regulatory quality and GFI inflows is warranted and will ultimately spur economic growth.

Molecular phylogeny of the common wall lizard Podarcis muralis (Squamata: Lacertideae) in the southern Balkans

Abstract The lacertid wall lizards of the genus Podarcis (Wagler, 1830) originate from Western Europe and are divided into 24-25 species (Speybroeck et al., 2020). Despite the abundance of phylogenetic studies referring to the genus, the relationships among certain species, as well as the taxonomic status of some genealogical lineages, remain unclear due to great genetic diversity. The common wall lizard Podarcis muralis has a relatively wide distribution and despite the existence of various molecular studies focused on this species, its Greek populations had never been thoroughly sampled until now. To fill in this geographical gap, we sampled the species’ Greek distribution and constructed phylogenies that uncovered the presence of at least five monophyletic lineages that correspond to different geographic regions. Furthermore, species delimitation analyses assigned all lineages to a single species diversifying during the early Pleistocene (c. 1.93 mya). The strong association of the genetic lineages with specific geographical regions coupled with the Pleistocene diversification of the group imply the presence of multiple refugia within Greece and, by extension, the Balkan peninsula, supporting a refugia-within-refugia scenario. Finally, in an effort to clarify the position of these new samples within the larger phylogeny of P. muralis, a larger phylogeny was constructed which indicated that the Greek populations cluster with the central European, Italian and Turkish populations of the species.

The Importance of Higher Education Quality for Mobility Intentions. Evidence from a Western Balkan Country

ABSTRACT The Western Balkan region confronts a pronounced brain drain phenomenon, as its highly educated youth seek enhanced opportunities abroad. Grounded in the Social Cognitive Theory, this paper explores the decision-making process of Macedonian youngsters and scrutinizes how personal, social, and educational factors shape their mobility intentions. The findings driven from a survey encompassing 1150 university students, obtained through descriptive analysis using Python 3.7 and Partial Least Squares Structural Equation Modeling via a high-level SEM tool for R, reveal valuable insights that describe the complex interplay of students’ expectations, subjective norms, higher education quality, and professors’ availability, crucial elements in mitigating brain drain trends. The implications delineate explicit obstacles to developing higher education quality, accentuating the importance of tailoring university services to students’ needs in terms of a better understanding of the higher education system’s potential. The conclusions identify indicators that can assist in describing the youngsters’ mobility intentions, contribute to monitoring the brain drain process through higher education attributes, and highlight strategies for facilitating the system’s competitiveness.

Polyphenolic Composition and Antimicrobial, Antioxidant, Anti-Inflammatory, and Antihyperglycemic Activity of Different Extracts of Teucrium montanum from Ozren Mountain.

Teucrium montanum has widespread use in folk medicine on the Balkan peninsula. In order to scientifically justify this use, the composition and biological activity of aqueous, ethanol, and acetone extract were investigated in this study. Moreover, acetone and ethanol extracts were obtained from the plant material previously exhausted by water extraction. A total of 27 compounds were detected in extracts by UHPLC-DAD-MS/MS analysis, with all of them present in acetone and ethanol extracts. Consequentially, the acetone and ethanol extracts showed higher contents of total phenols of 23% and 18%, respectively, compared to the water extract. The results indicated high biological potential in the investigated extracts. Among all extracts, the aqueous extract showed slightly higher antimicrobial potential, especially against Gram-positive strains, probably due to the release of components soluble in water from the dry unexhausted plant material. On the other hand, the acetone and ethanol extracts had significantly higher antioxidative (by 20%), anti-inflammatory activity (up to 3 and 4 times higher, respectively), and α-glucosidase inhibitory potential (3 times higher) than the aqueous extract. The results of this investigation reveal the great potential of the use of T. montanum in various branches of food, cosmetics, and the pharmaceutical industry. An important part of this research is a confirmation that, once exhausted by water extraction, for example by hydrodistillation, T. montanum plant material can be reused for obtaining valuable products with a wide range of biological activities.

The Spatiotemporal Evolution of the Growing Degree Days Agroclimatic Index for Viticulture over the Northern Mediterranean Basin

The agricultural sector faces significant challenges worldwide due to climate change. The pressure exerted by altered thermal conditions drives the zonal shift for various cultivations. This study aims to analyze and present the spatiotemporal evolution of the growing degree days (GDD) index in the northern Mediterranean Basin (NMB). More specifically, this research presents the multiyear analysis of the GDD index, which is focused on a high-value vine cultivation derived from the E-OBS dataset. The investigated time period spans from 1969 to 2018, and the performed analysis indicates a broad shift/expansion in areas with GDDs exceeding 2000 heat units. This is present in traditional winemaker countries such as France and Italy. Still, it is also evident that there is a high positive change in countries such as Serbia, Bulgaria, and other Balkans countries. The findings may be helpful in the strategic planning of the agricultural sector in these countries or on a vinery scale.

Short Run and Long Run Effects of Corruption on Economic Growth: Evidence from Balkan Countries

One of the factors that characterize the different countries of the Balkan area is the level of corruption which, as often stressed by scholars, may significantly influence the economic growth of its countries. However, there is still no agreement on the sign of this effect: there are theoretical arguments and empirical results in favor of a positive correlation between corruption and growth, and there are also theoretical arguments and empirical results that support the opposite view. The argument is that comparing the short-term and long-term impacts can help to explain the disparities. In this perspective, we propose an auto-regressive distributed lag (ARDL) methodology. This approach gives both short-run and long-run results simultaneously and it is robust with small samples. The results are not homogeneous for the eight countries covered by our study (Bulgaria, Croatia, Greece, North Macedonia, Romania, Serbia, Slovenia, and Turkey). The following theoretical intuition could be confirmed: although corruption could be seen as a factor that helps economic growth by speeding up the bureaucratic processing in the short run, conversely, in the long run, the social costs associated with corruption are considerable, making it difficult to sustain the political, economic, and social burdens, thus leading to a high level of corruption. These results confirm certain aspects of Albert Hircshman’s ideas regarding private interests and public action.

Assessment of Balkan Pepper (Capsicum annuum L.) Accessions for Agronomic, Fruit Quality, and Pest Resistance Traits

To maintain the continuous genetic variation and increase the genetic gain, appreciable germplasm diversity and its comprehensive characterization is necessary to further utilize gene sources for pre-breeding. The diversity of pepper forms, cultivation traditions and diverse fruit usages are typical for Balkan countries. Considering this rich diversity, 21 pepper accessions from the Balkan region were evaluated for morphological, biochemical, and insect resistance traits during 2018 and 2019 at Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgaria. Among the studied accessions, the highest productivity was observed in pumpkin shape K1115 and kapia type K1081 accessions, with 0.74 kg and 0.70 kg per plant, respectively. Concerning fruit quality, the highest total polyphenols and ferric reducing antioxidant power (FRAP) were observed in pumpkin shape K712 (203.44 mg GAE/100 g FW) and K1103A (11.49 µmol Fe2+/g FW) accessions, respectively. Concerning insect resistance, 38% of studied accessions showed no infestation of green peach aphid. The kapia type K697 accession was seen as the most reliable resistance source, as it was not infested by aphids and had the least thrips (20% on plants) and cotton bollworm (6.67% on plants and 8.34% on fruit) damage. Based on examined traits, accessions were identified for enhanced fruit quality and promising insect resistance and have been included in further pre-breeding efforts.

A lightweight framework for cyber risk management in Western Balkan higher education institutions.

Higher education institutions (HEIs) have a significant presence in cyberspace. Data breaches in academic institutions are becoming prevalent. Online platforms in HEIs are a new learning mode, particularly in the post-COVID era. Recent studies on information security indicate a substantial increase in cybersecurity attacks in HEIs, because of their decentralized e-learning structure and diversity of users. In Western Balkans, there is a notable absence of incident response plans in universities, colleges, and academic institutions. Moreover, e-learning management systems have been implemented without considering security. This study proposes a cybersecurity methodology called a lightweight framework with proactive controls to address these challenges. The framework aims to identify cybersecurity vulnerabilities in learning management systems in Western Balkan countries and suggest proactive controls based on a penetration test approach.

Health policy developments in the Western Balkan Countries 2000-19: towards European Health and Health Care Policies.

Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have committed to becoming European Union (EU) member states. This, among others, implies that candidate/potential candidate states adopt legally authorized EU policies, including health. The study aims to identify the main country-specific health policy areas critical to the EU accession health policy dimension and present the change in associated selected health indicators from 2000 to 2019. The study draws on published reports and analyses of official statistics over time and cross-country. Health care policy adherence to the European Commission's recommended country-specific health actions was classified into five health policy areas: financing, payment, organization, regulation and persuasion. Key health policy areas for Western Balkan countries (WBCs) were identified. Health progress or lack thereof in catching up to the EU15 population health, health expenditure and the number of health professionals are measured. The European Commission prioritized financing and regulation for all WBCs in the five policy areas. Nine of the 18 analyzed selected health indicators showed divergence, and the other nine converged towards the EU15 averages. WBCs continue to face diverse public health challenges in improving life expectancy at birth, death rates caused by circulatory system diseases, malignant neoplasms, traffic accidents, psychoactive substance use, tuberculosis incidence, tobacco smoking prevalence and public-sector health expenditure. By 2019, there is limited evidence of WBCs catching up to the average EU15 health levels and health care policies. Closer attention towards EU health and health care policies would be favourable.
