Environmental Deterioration, Renewable Energy, Natural Resource Rents, and Schooling in Türkiye: Does the Degree of Energy Transition Matter for Environmental Quality?
(Academic Press Ltd- Elsevier Science Ltd, 2024) Bulut, Umit; Atay Polat, Melike; Bulut, Ahsen Seda; Atay-Polat, Melike
Within the literature on energy and environmental economics, it is generally acknowledged that renewable energy can improve environmental quality; however, certain papers suggest that an optimal level of the usage of renewable energy sources may exist. Consequently, the utilization of renewable energy sources can result in environmental degradation up to a certain threshold. Then, environmental quality can be enhanced through the continued application of renewables. This indicates that the link between renewable energy and environmental devastation is inverted U-shaped. This paper presents empirical evidence concerning this possible association between renewable energy and environmental destruction in T & uuml;rkiye, a country where fossil energy predominates in the energy mix. Additionally, the paper investigates the environmental influences of natural resource rents and schooling. This study utilizes annual data from 1971 to 2020 and implements time series methodologies that rely on the Fourier approximation. The paper thus accounts for an undetermined quantity of structural breaks. The results suggest that an inverted U-shaped link occurs between renewable energy and environmental destruction, signifying renewable energy initially contributes to a diminution in environmental quality before subsequently improving it. Additionally, environmental quality is positively associated with natural resource rents and negatively associated with schooling, according to the findings. Furthermore, the findings reveal that schooling worsens the combined effect of renewable energy on environmental degradation. These conclusions are discussed in the paper.
Self-Control as a Key Mediator and Moderator of the Relationship Between Psychological Distress and Food Addiction in a Large Community Sample of Adults
(Academic Press Ltd- Elsevier Science Ltd, 2026) Ceylan, Jiyan Aslan; Korkmaz, Aziz; Hatipoglu, Abdulkerim; Akcali, Caglar; Coskunsu, Sedat
Objective: This study investigated the extent to which psychological distress (depression, anxiety, and stress) predicts food addiction (FA) symptoms and examined whether self-control operates as both a mediator and a moderator in these associations. Method: A total of 4234 adults (40.7 % male) participated in a large-scale, community-based, cross-sectional survey conducted in T & uuml;rkiye. FA symptoms were measured via the Yale Food Addiction Scale (YFAS), self-control was assessed via the Brief Self-Control Scale (BSCS), and psychological distress was evaluated via the Depression Anxiety Stress Scales (DASS-21). Statistical analyses were conducted in SPSS, with significance defined at p < 0.05. Results: Overall, 35.1 % of the participants met the criteria for FA, with no significant sex difference (p = 0.19). Logistic regression analyses revealed that greater anxiety (OR = 1.078, p < 0.01) and stress (OR = 1.109, p < 0.01) were significant predictors of increased risk for FA, whereas greater self-control emerged as a protective factor (OR = 0.952, p < 0.01). Mediation analyses confirmed that self-control partially accounted for the effects of psychological distress on FA symptoms, with significant indirect effects observed for stress (beta = 0.025), anxiety (beta = 0.029), and depression (beta = 0.032). Moderation analysis revealed that self-control attenuated the effect of depression on FA symptoms (interaction term: B = 0.002, p < 0.01), although no moderating effects were found for anxiety or stress. Conclusions: This study highlights self-control as both a mechanism through which psychological distress contributes to food addiction and a protective factor that reduces its impact. Enhancing self-control may help mitigate addiction-related eating behaviors.
Tissue Type and Cultivar-by-Isolate Interactions Govern Walnut (Juglans Regia) Resistance to Diaporthe Eres in Türkiye
(Academic Press Ltd- Elsevier Science Ltd, 2026) Orman, Erdal; Ozer, Goksel; Polat, Zuhtu; Dervis, Sibel; Turkkan, Muharrem; Gultekin, Mehmet Akif
Diaporthe eres is increasingly reported as a causal agent of canker, shoot dieback, and fruit rot of walnut (Juglans regia L.) in diverse production regions. In this study, multi-locus phylogenetic analysis using ITS, tef1, and tub2 gene sequences confirmed that two isolates, ED 5/4 (Edirne) and BUR 7/4 (Bursa), belong to D. eres sensu stricto, showing 99-100% sequence identity with ex-type strain AR5193 in BLASTn analysis and clustering with high bootstrap support in Maximum Likelihood phylogenetic trees. Pathogenicity assays conducted on green fruits, current-season shoots, and one-year-old dormant branches of seven cultivars revealed strong and statistically significant cultivar & times; isolate interactions, demonstrating that resistance responses were highly isolate-specific. Isolate BUR 7/4 displayed higher virulence overall than ED 5/4. Lesion development differed markedly among tissue types, with current-season shoots consistently exhibiting substantially greater necrosis than oneyear-old dormant branches, indicating a pronounced influence of tissue ontogeny on host susceptibility. Cultivar performance varied among tissues: 'Chandler' showed the greatest resistance in woody tissues, whereas 'Fernor' and 'Orman 77 ' were consistently susceptible. Fruit assays demonstrated variable husk susceptibility but uniformly severe, cultivar-independent kernel decay, indicating the absence of internal resistance once the husk barrier was breached. D. eres was re-isolated from all symptomatic tissues while controls remained healthy, fulfilling Koch's postulates. These results establish D. eres as an important contributor to walnut canker and fruit rot in Türkiye and emphasize the roles of tissue-specific susceptibility, isolate diversity, and cultivar-dependent responses in shaping disease outcomes and informing resistance-based management strategies.
