This study presents the results of indoor radon measurements collected during three survey campaigns, accumulating around 450 data taken in dwellings, public buildings, and workplaces. The first stage of the study focused on refining the database, which included only 220 measurements taken on the ground floors of dwellings. The information collected from the largest cities in twelve administrative areas of Albania showed that approximately 30

The activity concentrations of indoor radon were assessed in the three buildings of the University of Aleksandër Moisiu Durrës. The measurements were conducted utilizing the passive technique that relies on CR-39 solid-state nuclear track detectors. Measurements were performed at various floors during both warm and cold weather conditions. In a specific case, the active technique was used, and radon concentrations were compared between day and night over a span of approximately two weeks. The yearly average radon concentrations were found to vary between 20 and 92 Bq m−3. The average dose due to indoor radon exposure was estimated at 0.6 mSv annually. These findings suggest there was no significant radiological health risk, since the observed activity concentration levels were far below the reference level of 300 Bq m−3 set in Albanian legislation for workplaces.

The tourism industry is highly competitive, and sustaining customer loyalty is crucial for the success of businesses within this sector. In the dynamic and competitive landscape of the tourism industry, understanding the factors that influence customer loyalty is crucial for sustainable business success. This study explores the interplay between perceived value, customer expectations, trust, and their collective impact on customer loyalty within the context of the tourism industry. This reserch is focused on the Albanian tourism industry, especially in 3- and 4-stars hotels that operate in the city of Durres. Statistical tests included descriptive statistics, internal consistency, reliability, validity, correlation, and regression were conducted to determine the relationship and to validate the study. The survey for this study has been applied to 580 tourist that has been accommodated in different hotels of 3 and 4 stars in Durres, from May to September 2023. The study found that there is a positive relationship between perceived value and customer loyalty, customer expectation and customer loyalty, trust and customer loyalty. All those variables are considered predecessors of customer loyalty. By examining these interrelationships, this research contributes valuable insights to the tourism industry, helping hotels in Durres to understand the dynamics that drive customer loyalty in the development of long-term loyalty to contribute to the sustainability and success of their businesses in this competitive industry.

Albania has 270 certified agrotourism establishments generating over €12 million annually. Operators face long waiting times, underutilized capacity, and supply chain delays. We propose an integrated framework combining Graph theory for structural network analysis with Timed Petri Nets for dynamic process modeling, applied to the Shkodra region. Using road distances from GIS and OpenStreetMap, we construct a weighted network of 40+ centers. Structural analysis identifies Harapi (degree 4, betweenness 0.35) and Faqedol (degree 3) as the most central nodes. Accessibility analysis reveals high spatial inequality (CV = 0.52). We build and simulate a Timed Petri Net model in CPN Tools, parameterized with site visit data. The tourist flow model identifies the activity stage as the primary bottleneck (90% utilization). The supply chain model shows processing as the main constraint (4 hours average). We propose a practical step-by-step implementation framework for applying Petri Nets in agrotourism. Combined structural and dynamic analysis shows that targeted interventions can increase throughput by 30%, from 45 to 60 tourists per day.

This paper examines the legal regime governing strategic investments in Albania, established by Law no. 55/2015 "On Strategic Investments in the Republic of Albania", focusing on the tension between encouraging investment and safeguarding transparency and fair competition. Through a dual approach — legal and empirical — the study analyses the normative framework regulating the approval procedures, the status of the strategic investor, and the administrative and fiscal incentives, comparing them with European Union standards. The empirical analysis draws on the register of decisions of the Strategic Investment Committee published by the Albanian Investment Development Agency, on official audit and monitoring reports, and on the findings of the EU Report on Albania, in order to assess whether the practical implementation of the law has led to market concentration in the hands of a limited number of operators. Findings show that, a decade after its adoption, the regime — repeatedly extended and currently in force until December 2026 — has produced 55 grants of strategic status with a declared value of roughly EUR 8.8 billion, concentrated overwhelmingly in the tourism and coastal real-estate sector (about 70 per cent of projects and 71 per cent of declared value) and dominated by domestic rather than foreign investors. The results suggest that the broad discretionary power of decision-making bodies and the lack of strong accountability mechanisms increase the risk of distorting competition and weaken public trust. The paper argues that strengthening transparency, publishing contracts, and ensuring independent oversight are preconditions for compliance with the EU acquis. In conclusion, it proposes concrete recommendations for reforming the law towards a more open, competitive, and transparent investment model
