Comparing how energy policy uncertainty, geopolitical risk, and R&D investment shapes renewable energy and fossil fuels
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Karlıer Pata, Selin; Pata, Uğur Korkut
This study examines the comparative impact of energy policy uncertainty, geopolitical risk, and R&D expenditures on renewable and fossil fuel consumption in China from 2002m1 to 2022m12, using Fourier ADL, fully modified and dynamic ordinary least squares methods. The analysis aims to clarify how these key factors shape the country’s energy transition. The results show that energy policy uncertainty significantly promotes renewable energy but has no significant impact on fossil fuel consumption. Geopolitical risk increases the adoption of renewables, while fossil fuel consumption decreases, reflecting concerns about energy security. R&D expenditure contributes to the growth of both renewable and fossil fuel consumption, indicating a dual investment path in China’s energy strategy. These findings underscore the importance of consistent energy policies, reduced reliance on imported fossil fuels, and targeted R&D investment to support China’s transition to a low-carbon energy future. To effectively promote renewable energy and reduce dependence on fossil fuels, China should stabilize its energy policy environment, redirect R&D funding to clean technologies, and treat geopolitical risks as a strategic driver to accelerate domestic renewable energy capacity and energy self-sufficiency.
Comparative cranial and postcranial osteology of blanus species (squamata: amphisbaenia) from Türkiye: insights from morphological evolution and phylogeny

The genus Blanus (Amphisbaenia: Blanidae) comprises fossorial, limbless reptiles with cryptic external morphology, making species delimitation particularly challenging. This study presents a comprehensive comparative osteological and geometric morphometric investigation of three Blanus species distributed in Türkiye—B. alexandri, B. aporus, and B. strauchi. Using both dry and cleared-and-stained specimens, diagnostic variations in cranial and postcranial skeletal elements, especially elements within the nasal, maxilla, vomer, squamosal, dentary, and coronoid bones, as well as vertebral counts were identified. A geometric morphometric analysis of the dorsal and ventral cranial morphology revealed distinct shape differences, particularly separating B. alexandri from the other two species along principal component axes. A phylogenetic analysis based on 45 discrete osteological characters supported the monophyly of the eastern Blanus clade, with B. alexandri forming a distinct lineage from B. aporus and B. strauchi. These findings emphasize the significance of skeletal morphology for resolving phylogenetic relationships and highlight the role of osteological characters in refining species boundaries within cryptic reptilian taxa. The integrative approach employed here underscores the evolutionary distinctiveness of Anatolian Blanus and enhances our understanding of morphological evolution in amphisbaenians.
Living with hypertension: an investigation of illness perception from a primary care perspective
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Duman, Handan; Yıldız, Latife Merve
Background: This study aimed to assess the illness perceptions of patients diagnosed with hypertension from a primary care perspective. It also sought to identify the sociodemographic and clinical factors associated with illness perception. Methods: A cross-sectional descriptive study was conducted between February and March 2025, involving 116 hypertensive patients who attended family medicine outpatient clinics at Rize Training and Research Hospital, Turkey. Data were collected using a sociodemographic questionnaire and the Brief Illness Perception Questionnaire (BIPQ). Nonparametric tests, including the Mann–Whitney U test, Kruskal–Wallis H test with Dunn’s post hoc analysis, and Spearman’s correlation analysis, were employed to evaluate the data. Results: The mean age of the participants was 69.01 ± 6.07 years, with 76.7% of the participants aged over 65 years. The median total BIPQ score was 47.0, indicating a moderate illness perception. A significant negative correlation was observed between age and the total BIPQ score (Rho = −0.443, p < 0.001). Higher illness perception levels were significantly associated with lower educational attainment, shorter duration of antihypertensive treatment, and attribution of hypertension to stress, genetic predisposition, diet, and occupational factors (p < 0.05). Conclusions: Illness perceptions among patients with hypertension are shaped by various sociodemographic and clinical determinants. Enhancing awareness of these perceptions in primary care may support improved treatment adherence and better health outcomes. Interventions that strengthen health literacy and offer psychosocial support may contribute to more effective hypertension management.
From the demon to the secret voice: archetypal echoes and oral culture in 19th century romantic poetry
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Öztürk, Gül Mükerrem
The first half of the 19th century witnessed the rise of Romantic poetry, which focused in depth on individual consciousness, inner worlds, and metaphysical inquiries. This poetic orientation became particularly evident in works centred on themes such as solitude, alienation, and existential quests. Within this context, the present study aims to examine the archetypal and poetic resonances of the poetic voice in Mihail Lermontov’s poem The Demon, based on its sixth and final version dated 1841, in relation to Nikoloz Baratashvili’s poem Secret Voice. Lermontov’s poem is analyzed through the English translation by Charles Johnston, published in 1983, while Baratashvili’s poem is discussed based on the 24-line version included in the fifth edition (1895) of the anthology Poems and Letters (Leksebi da Tserilebi). This study explores the thematic and structural similarities between the two poems within the framework of comparative literature and psychoanalytic criticism, focusing on Romantic archetypes, the uncanny, the shadow figure, and ontological solitude. Furthermore, the dialogue established between Lermontov’s demonic narrator and Baratashvili’s introspective poetic voice reopens discussions on the boundaries of cultural memory, oral narrative patterns, and poetic identity. Ultimately, this comparative analysis reveals the implicit influences of The Demon on Georgian poetry and discusses the intercultural resonances of themes such as voice, self, and archetype in Romantic poetry.
Association of low free T3 with disease presence and activity in ankylosing spondylitis
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Çiftel, Enver; Klisic, Aleksandra; Kızılkaya, Bayram; Cüre, Osman; Mercantepe, Filiz; Karakaş, Sibel Mataracı; Ninić, Ana
Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by axial skeletal involvement and systemic metabolic changes. While inflammation is central to its pathophysiology, the potential role of thyroid hormones, particularly free triiodothyronine (FT3), in disease risk and activity remains underexplored. The objective of this study is to evaluate the relationship between serum FT3 levels and both the presence and clinical activity of AS, while also examining other endocrine-metabolic parameters. In this cross-sectional study, 120 AS patients and 117 healthy controls were assessed. Demographic, anthropometric, hematologic, and biochemical parameters were recorded. Disease activity was determined using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), with BASDAI ≥ 4 indicating active disease. Logistic regression models adjusting for age, sex, BMI, and other relevant covariates were applied to identify independent predictors. FT3 levels were significantly lower in AS patients compared to controls (3.25 [3.01–3.58] vs. 3.44 [3.16–3.69] pg/mL, p = 0.037) and in patients with BASDAI ≥ 4 versus BASDAI < 4 (3.20 [2.94–3.48] vs. 3.44 [3.19–3.83] pg/mL, p = 0.004). The reduction was more evident in women, where it reflected disease presence, whereas in men it was associated with high disease activity. Low FT3 independently predicted both AS (OR 0.50, 95% CI 0.28–0.92, p = 0.026) and active disease (OR 0.48, 95% CI 0.24–0.99, p = 0.047). Lower HDL-C, BMI, and creatinine, and higher leukocyte counts were also associated with AS, but not with disease activity. Low-normal FT3 is independently associated with both the presence and activity of AS, reflecting disease presence in women and disease activity in men. This is the first study to demonstrate this sex-specific association after adjusting for metabolic parameters and multiple covariates, highlighting FT3’s potential as a marker of inflammation-driven metabolic dysregulation.
