1. Time-money segment differences in ideation and collaboration readiness in sustainable tourism educationDejan Križaj, 2026, izvirni znanstveni članek Opis: 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. Occupational and non-occupational device-measured movement behaviours and low back pain : a compositional isotemporal substitution analysisKaja Kastelic, Nejc Šarabon, Michael David Burnard, Željko Pedišić, 2026, izvirni znanstveni članek Opis: Background: Physical activity, sedentary behaviour, and sleep were shown to be independently associated with low back pain (LBP). The aim of this cross-sectional study was to explore the associations between 24-hour movement behaviour compositions and the occurrence, severity, and estimated level of LBP impact on an individual’s life. Methods: A convenience sample of 197 adults (40% females, 37 ± 11 years of age) were asked to wear an activPAL accelerometer for at least 7 consecutive days to assess their time-use composition consisting of moderate- to vigorous-intensity physical activity (MVPA), light- intensity physical activity (LPA), sedentary behaviour (SB), and sleep and to complete a questionnaire on LBP and sociodemographic characteristics. Compositional isotemporal substitution analyses were conducted separately for the non-domain-specific and domain- specific (including occupational and non-occupational domains) movement behaviour compositions. Results: Reallocating time from MVPA to any other movement behaviour or from sleep to LPA was associated with a higher LBP impact score. For example, reallocating 60 min/day from MVPA to LPA was associated with on average 17 points (95% CI: 6 to 28) higher LBP impact score (on a 0-70 scale). We did not find significant associations between the domain- specific time-use composition and LBP impact score (p = 0.060). We also did not find significant associations of the time-use compositions with occurrence and severity of LBP (p- value range: 0.067 to 0.649). Conclusion: Our study suggests that LBP sufferers with higher MVPA and sleep better cope with LBP. The differences in the LBP impact scores associated with theoretical reallocations between movement behaviours may be deemed clinically important. Future longitudinal and experimental studies in population-representative samples are needed to confirm our findings.

3. Adherence and metabolic outcomes of early and late time-restricted eating with energy restriction vs. energy restriction alone : a 6-month follow-upTanja Črešnovar, Bernarda Habe, Nina Mohorko, Saša Kenig, Zala Jenko Pražnikar, Ana Petelin, 2026, izvirni znanstveni članek Opis: Background/Objectives: Long-term weight maintenance remains challenging with conventional dietary strategies due to various barriers. Time-restricted eating (TRE) has recently attracted attention as a potential approach to improve adherence, but evidence on long-term maintenance is limited. We investigated the 6-month follow-up (6FU) of early time-restricted eating with energy restriction (eTRE + ER), late time-restricted eating with energy restriction (lTRE + ER) and energy restriction alone (ER). Methods: This 6FU included 69 of 93 participants from a previously conducted 3-month intervention (3INT). After the intervention, participants returned to free-living conditions without dietary guidance. Outcomes included adherence, perceived barriers, body composition, blood pressure, cardiometabolic risk factors, metabolic hormones, subjective appetite, and dietary intake. Results: Adherence of at least ≥5 days per week was low: 7.7% (eTRE + ER), 18.2% (lTRE + ER), and 9.5% (ER). Reduced adherence during the 6FU was associated with a partial reversal of improvements in body mass, body composition, cardiometabolic risk factors, metabolic hormones, and subjective appetite observed during the 3INT. Analysis of perceived barriers showed that environmental and psychosocial barriers were significant predictors of changes in body mass during the 6FU, while environmental and behavioral barriers were associated with extension of the eating window. These associations were most pronounced in the eTRE + ER group. Conclusions: During the 6FU, differences between dietary strategies gradually diminished, although some remained clinically meaningful. Long-term adherence was low across all three dietary strategies, with psychosocial, environmental, and behavioral barriers particularly evident in the eTRE + ER group. Further research is needed to confirm long-term adherence before TRE + ER interventions can be widely applied in clinical practice.

6. Exploring the drivers of farm sustained participation in agri‑environmental programmesŠtefan Bojnec, Imre Fertő, 2025, izvirni znanstveni članek Opis: This paper examines the socioeconomic and institutional determinants influencing sustained participation in Agri-Environmental Climate Schemes (AECS), drawing on comprehensive panel data from Slovenian farms covering the period 2014–2021. Using discrete-time hazard models and nonparametric duration analysis, we identify economic resilience—characterised by larger farm size, income diversification, and prior participation—as a significant driver of prolonged AECS engagement. Conversely, greater dependence on market-based income is negatively correlated with long-term participation, highlighting inherent trade-offs between short-term economic gains and sustained ecological commitments. Additionally, educational attainment exhibits a modest yet positive association, emphasising the importance of knowledge dissemination and capacity building in facilitating the responsible use and sustained environmental protection. Our findings underscore the necessity for context-specific policy designs, advocating diversified financial incentives, robust extension services, and market-aligned strategies to effectively integrate agricultural productivity with environmental sustainability.

7. Early time-restricted eating with energy restriction has a better effect on body fat mass, diastolic blood pressure, metabolic age and fasting glucose compared to late time-restricted eating with energy restriction and/or energy restriction alone : a 3-month randomized clinical trialTanja Črešnovar, Bernarda Habe, Nina Mohorko, Saša Kenig, Zala Jenko Pražnikar, Ana Petelin, 2025, izvirni znanstveni članek Opis: Background & aims Time-restricted eating (TRE) has attracted increasing attention from researchers and the public. Recent studies suggest that the combination of TRE with energy restriction (ER) may have more favourable effects on both physical and biochemical aspects compared to ER alone. The aim of the present 3-month intervention study was to determine the effects of an 8-h early time-restricted eating and an 8-h late time-restricted eating with ER (eTRE + ER and lTRE + ER) compared to 12-h ER alone on body mass and other anthropometric and cardiometabolic risk factors in participants with overweight and obesity. Methods Participants (n = 108) were allocated to three different groups according to their personal chronotype: eTRE + ER (37 participants), lTRE + ER (37 participants) and ER (34 participants). Ninety-three participants completed the entire 3-month intervention (34 in eTRE + ER, 28 in lTRE + ER and 31 in ER). Anthropometric and cardiometabolic risk factors were measured at baseline and after 1, 2 and 3 months of the intervention. Sleep quality and quality of life were assessed at baseline and after 3 months of the intervention. ER was determined based on the individual's resting metabolic rate. Effects were analyzed using the per-protocol approach. Results Results showed a significant time main effect (p < 0.001), suggesting a decrease in body mass at the end of the 3-month intervention with a mean loss of −5.0 kg (95 % CI, −5.7, −4.3) for the eTRE + ER group, −4.4 kg (95 % CI, −5.2, −3.6) for the lTRE + ER group and −4.3 kg (95 % CI, −5.0, −3.6) for the ER group, with no significant difference between the groups (p = 0.319). eTRE + ER had greater improvements in fat mass (−1.2 % (95 % CI, −2.1, −0.2), p = 0.013) and fasting glucose (−0.35 mmol/L (95 % CI, −0.63, −0.06), p = 0.012) than participants in the lTRE + ER group and greater improvements in fat mass (−1.1 % (95 % CI, −2.0, −0.1), p = 0.022), metabolic age (−3 years (95 % CI, −5, −0), p = 0.028) and diastolic blood pressure (−4 mmHg (95 % CI, −8, −0), p = 0.033) than the participants in the ER group. No significant changes were found between the groups for the other parameters measured. Conclusions There was no difference in body mass between the eTRE + ER, lTRE + ER and ER groups after 3 months of intervention. However, eTRE + ER showed a greater benefit for fasting blood glucose, certain anthropometric parameters and diastolic blood pressure compared to lTRE + ER and/or ER alone. Other anthropometric, biochemical and health-related parameters were not affected by eating window.
