Animal remains from the archaeological site "Ancient City of Zaldapa – Tetraconch Church Sector," (NE Bulgaria)
(Plovdiv University Press "Paisii Hilendarski", 2026-10-17) Boev, Zlatozar
This study presents the archaeozoological analysis of animal remains recovered from the archaeological site of the Ancient City of Zaldapa, Tetraconch Church Sector, in northeastern Bulgaria. The examined material comprises 295 bone and tooth fragments and mollusc shells collected from 46 samples during archaeological excavations conducted between 2024 and 2026. A total of 22 taxa were identified, including domestic mammals, poultry, wild mammals, fish, and molluscs.
Challenges and Adaptive Solutions for the Adoption and Scaling of Nature‑based Solutions in three Central and Eastern European regions: A Comparative Regional Analysiс
(Plovdiv University Press "Paisii Hilendarski", 2026-10-12) Popov, Vladislav; Grozdanova, Dafinka; Bileva, Tatyana; Valcheva, Ekaterina; Ivanova, Dafinka; Petrova, Slaveya; Tarau, Gabriela; Nenad, Mirjana
Nature‑based solutions (NbS) are increasingly promoted as a multi‑benefit pathway for climate adaptation, disaster risk reduction, biodiversity recovery, and sustainable regional
development. Yet, mainstreaming NbS into sub‑national planning and investment pipelines remains uneven across Europe. This paper addresses the research question: What are the
challenges and suitable adaptive solutions for the adoption of NbS in the Plovdiv, Centru, and Podravje regions, situated in Bulgaria, Romania, and Slovenia, respectively? Drawing on several EU research project ARCADIA documents, e.g., the regions’ self‑assessment, the comparative analysis of the fellow regions, and review materials, the study team conducted a structured comparative policy and governance analysis using the ARCADIA common assessment pillars (governance, climate risk assessment, and adaptation planning). Results show that (i) Plovdiv region (Bulgaria) combines strong EU policy alignment with fragmented regional execution and NGO‑dependent coordination; (ii) Centru region (Romania) exhibits a comprehensive multi‑tier governance and strategic planning orientation but is slowed by inter‑agency complexity and data and monitoring gaps; and (iii) Podravje region (Slovenia) presents a coherent, performance‑driven model with stronger NbS integration and monitoring, but faces constraints related to municipal‑level funding boundaries, social acceptance, and local decision‑maker knowledge. Across all regions, the most limiting factors include weak vertical coordination, inconsistent monitoring frameworks, and insufficiently institutionalized stakeholder platforms. The study proposes a portfolio of adaptive NbS governance and policy solutions and instruments such as clarifying mandates and establishing regional coordination hubs; adopting KPI‑based and learning‑oriented monitoring; developing co‑innovation labs and twinning pathways for capacity building; and introducing results‑based financing and blended funding structures. The paper concludes with region‑specific and cross‑regional recommendations to accelerate NbS mainstreaming while respecting diverse administrative architectures.
HOW RECENT CJEU RULINGS CHANGED THE FOOTBALL REALITY IN EUROPE?
(Plovdiv University Press, 2026-10-08) Raychev, Kristian
In the period between December 2023 and August 2025, the Court of Justice of the European Union (CJEU) delivered a series of judgments that substantially reconfigured the legal framework governing professional football in Europe. In European Superleague Company (C-333/21), Lassana Diarra (C-650/22), and Royal Football Club Seraing (C-600/23), the Court recalibrated the balance between the autonomy of sport and the requirements of EU law in the fields of competition, free movement, and effective judicial protection. This article examines how, taken together, these three judgments constrain the regulatory discretion of FIFA and UEFA by imposing requirements of transparency, proportionality, and judicial review in areas that have traditionally been governed through private-law sports regulation. Particular attention is devoted to the Diarra judgment and to FIFA’s subsequently adopted Interim Regulatory Framework amending the Regulations on the Status and Transfer of Players (RSTP), assessing whether that framework substantively complies with the reasoning of the CJEU or instead merely seeks to mitigate the immediate effects of the ruling. In conclusion, the article advances the thesis that European football is entering a phase of “controlled autonomy,” in which private sports governance remains legitimate only insofar as it operates within a legally contestable framework compatible with market principles.
CHANGES IN PASSENGER TRANSPORTATION LAW ON A NATIONAL AND REGIONAL LEVEL IN BULGARIA
(Plovdiv University Press, 2026-10-08) Kazandzhiev, Teodor
Frequent amendments of laws and ordinances often cause problems in their application and interpretation. It is no different for the acts which regulate the transportation of passengers. The article aims to find a solution to these issues and attempts to answer the question: “How often should a legal act be changed in order to keep up with social and legal changes and without becoming unclear?” A comparison is made to Roman law, where amendments were seldom implemented, and to Common Law, where certain regulations have remained unchanged for a substantially long period of time which highlights the importance of balanced and well-prepared amendments. The importance of the discussed issue goes beyond the strict framework of Commercial or Roman Law. Nonetheless, the focus is on passenger transportation law, which is regulated by a multitude of laws, ordinances and various other legal acts.
THE CHALLENGE OF CASE LAW OF THE COURT OF JUSTICE OF THE EUROPEAN UNION ON THE REGULATION OF COMMERCIAL TRANSACTIONS
(Plovdiv University Press, 2026-10-08) Koleva, Zhana
Relevant for the study is Directive 2011/7/EU on combating late payment in commercial transactions1. On one hand, the regulations are liberal as they provide free access to the EU internal market and equal treatment of all participants there. On the other hand, they provide high protection of creditors` rights. The Directive does not harmonize fully all the rules relating to late payments in commercial transactions and Member States may adopt different ones. Nevertheless, the new rules must be settled in favor of creditors. However, in accordance with the principle of equality and uniform application of EU law, the concepts of the Directive are autonomous and should be interpreted uniformly in all Member States. This challenges national doctrine and practice and changes long-standing traditions and concepts.
