1. Time-money segment differences in ideation and collaboration readiness in sustainable tourism educationDejan Križaj, 2026, original scientific article Abstract: This study examines whether tourism students’ self-reported time–money use patterns are related to their readiness to collaborate on idea development, and whether sustain- ability emerges spontaneously in their tourism innovation ideas. Using an anonymised dataset of open-ended questionnaire responses from Slovenian higher education tourism students (N = 597; 2019–2025), we applied deterministic rule-based coding to classify the presence of actionable ideas and sustainability framing, as well as collaboration readiness and conditions. Actionable ideas were common (53.4%), but sustainability framing was uncommon (7.5%). Most respondents were unconditionally willing to collaborate (69.3%), while 30.7% expressed conditional willingness or unwillingness. Time–money behavioural segments were significantly associated with collaboration reservations, whereas segment differences in ideation and sustainability framing were not significant. Among students expressing reservations, topic match and perceived team quality were the most frequently stated conditions. These findings indicate that sustainability-oriented tourism education should support both sustainability integration and low-risk collaboration through clear project briefs, topic-based matching, and team-process supports. The conclusions should be interpreted with reasonable caution as they are context-specific evidence based on self- reported, rule-coded responses, particularly for sustainability framing, where positive cases were rare. In this context, segmentation should be regarded as a diagnostic tool for course design rather than as a basis for labelling students.

2. The Osor Aquatorium : An Overview of Underwater Archaeological ResearchZrinka Ettinger Starčić, original scientific article Abstract: In the Kvarner area and the Cres-Lošinj archipelago, Osor is the oldest and most significant island settlement, as well as the best-researched archaeologically. In addition to land-based archaeological surveys and research, ongoing since the late 19th century, the seabed of the entire island area has been systematically surveyed and studied. Particular attention has been given to the Osor seabed, due to the importance and value of the material culture originating from the settlement itself. This article presents all previous research conducted over the past 70 years, chronologically divided into two main periods: the first systematic research during the second half of the 20th century, and more recent systematic and protective research in the early decades of the 21st century. The results of these activities certainly complete the picture of the way and dynamics of life in this island centre throughout different historical periods, especially from the perspective of ancient seafaring, navigation, and Osor’s role in established transport and economic communications.

3. Selected Glass Finds from Apsorus (Osor) – Reflection of Wealth and PrestigeIrena Lazar, original scientific article Abstract: The article focuses on selected glass finds from Osor. The exact provenance of the finds is unknown; most likely, they were discovered in a Roman necropolis of Apsorus. Among the excavated materials, early products of Roman glassmaking, dated to the 1st century AD, stand out and illustrate the remarkable diversity of glassmaking technological practices of the period. Some of them were still made in moulds, others by mould-blowing, but we should also mention the earliest blown products. Imports of these products in Roman towns and cities along the Adriatic reflect the economic strength of the population and an extensive trade network expanding from northern Italy to the Eastern Mediterranean.
Keywords: Osor, Roman glass, moulds and mould-blowing, trade, import

4. International Trade and Economic Growth in an Oil-Dependent Country: Case of NigeriaOludayo Adekunle, 2025, original scientific article Abstract: This paper examines the effect of disaggregated international trade on the economic growth of Nigeria. The data and specified model were analysed with Autoregressive Distributed Lag and Toda-Yamamoto techniques. It was found that both non-oil and oil exports enhance economic growth. However, non-oil and oil imports impede economic growth. Furthermore, overall causality results revealed that while non-oil and oil exports and non-oil imports had bi-directional causality with economic growth, nonoil imports did not have causality with economic growth. Consequently, the government should prioritise export-led policy to facilitate economic performance in Nigeria. Findings emphasised the need for the diversification of the economy for higher economic growth and sustainability inthe long run. The paper enriches the literature on the relationship between international trade and economic growth in Nigeria by adequately disaggregating trade components to reflect the economic structure of the Nigerian economy. Also, it brings new empirical findings on the trade-growth relationship in an oil-dependent developing country. This study can provide a theoretical framework for research in countries that oil dependent.

5. Can Increased Intra-Continental Trade Partnerships Diversify Export Baskets in Africa?Sibusiswe Mchani, Andrew Phiri, 2025, original scientific article Abstract: The study investigates the potential of the African Continental Free Trade Area (AfCFTA) agreement in fostering diversified export baskets through increased intra-continental trade partnerships. It aims to evaluate how these trade partnership influence export diversification within Africa. Using network analysis, it develops three indices to measure the degree, closeness, and prestige of trading partners across 54 African countries from 2000 to 2020. These indices, along with traditional estimators, reveal two key findings. Firstly, the quality of trade partnerships, focusing on ‘who’ a country trades with, holds more significance than quantity. Secondly, there is a geographical imbalance, where the effect of trade partnerships turns negative for countries with higher product diversification. In conclusion, while intra-continental trade diversification shows promise, more advanced African nations may experience diminishing returns, suggesting a need for expanding trade networks beyond the continent for sustained export diversification.
Keywords: trade partner diversification, product diversification, AFCFTA agreement
