Article Time-Varying Sectoral Exchange Rate Pass-through and Its Structural Drivers: The Case of Turkish Manufacturing Industries(Springer, 2026-04-29) Saygılı, HülyaThis study examines how exchange rate pass-through (ERPT) varies across manufacturing sectors and which structural factors account for this heterogeneity over time. As a first step, the study constructs sector-level nominal effective exchange rate indices, generating a unique dataset that allows exchange rate movements to be matched directly to sector-specific trade structures. Using these indices, ERPT is estimated for Turkish manufacturing industries within a heterogeneous panel data framework. To enable systemic cross-sector comparison, a relative pass-through measure is developed that benchmarks each sector's ERPT against the manufacturing sector average. The analysis further explores the role of key structural characteristics-including trade openness, productivity, and global value chain participation-in shaping sectoral ERPT dynamics. The empirical results reveal significant disparities in pass-through across sectors, with persistent differences in sensitivity of exchange rate fluctuations. Structural determinants exhibit asymmetric effects: higher trade openness and deeper productivity tends to dampen ERPT. These findings highlights the importance of sector-specific characteristics for inflation dynamics and offer valuable policy insights for monetary and trade policy design.Article The Role of Motivational Interviewing in Enhancing Birth Self-Efficacy and Birth Satisfaction: A Randomized Controlled Study(Springer Publishing Co, 2025-11-25) Ozkan, Birgul; Sari, TugbaChildbirth is a critical and transformative experience in a woman's life; however, it is often accompanied by fear and perceived as a highly stressful event. Fear of childbirth may adversely affect a woman's confidence in her ability to give birth and her perceived competence regarding the birthing process. This study aimed to investigate the effect of motivational interviewing on childbirth self-efficacy and birth satisfaction among pregnant women. The study sample consisted of 85 pregnant women who were randomly assigned to either an intervention or a control group. Participants in the intervention group attended motivational interviewing sessions conducted over a 4-week period. Mode of birth and birth satisfaction were evaluated during the postpartum period. Among women in the intervention group, nearly 70% had a vaginal birth, and approximately 63% reported being satisfied with their childbirth experience. A statistically significant difference was observed between the groups in total childbirth self-efficacy scores following the intervention. The findings indicate that motivational interviewing can enhance childbirth self-efficacy and decrease the preference for cesarean birth.Trial registration: Registered in the ClinicalTrials.gov (NCT06082895).Article The Influence of Postural Load and Early Aging on Dynamic Sound Localization: Evidence for Reduced Cognitive-Motor Reserve(Springer, 2026-04-23) Batuk, Isa Tuncay; Batuk, Merve Ozbal; Karakuluk, IremThis study investigated the effects of head movements and postural stability on sound localization performance in normal-hearing adults and explored age-related differences between individuals aged 20-30 and 30-40 years. A total of 102 participants were divided into two groups: Group 1 (n = 56, 20-30 years) and Group 2 (n = 46, 30-40 years). Using a virtual reality system, localization performance was assessed under three different postural conditions and two listening conditions (head-immobile and head-mobile). Localization errors were measured at a 55-cm distance across four azimuth angles (right-front, left-front, right-back, left-back). Primary outcome measures included Azimuth Error, Front-Back Confusions, and Overall 3D Error. Incorporating head movements resulted in a statistically significant improvement in localization performance across all surface conditions (p < .001). In the head-mobile condition, the sitting posture yielded significantly lower Front 3D Error compared to both firm (p = .005) and foam surfaces (p = .007). Age-related differences were found to influence localization performance across varying levels of postural stability. Group 2 demonstrated significantly higher localization errors than Group 1 in the sitting condition (e.g., Head-Immobile Overall 3D Error: p = .021) and on the foam surface (e.g., Head-Immobile Overall 3D Error: p = .046). Conversely, no significant differences were found between the groups for any parameter on the firm surface. These findings indicate that head movements substantially enhance spatial hearing accuracy. However, localization performance is modulated by postural stability and age. Increased postural challenge appears to impose a dual-task cost, revealing subtle early age-related changes in the cognitive-motor mechanisms underlying auditory-spatial integration.Article Stochastic Comparisons of Mixtures of Heterogeneous Geometric Distributions Associated with Shock Models(Springer Heidelberg, 2026-05-14) Amini-Seresht, Ebrahim; Lorvand, Hamed; Balakrishnan, NarayanaswamyIn this paper, we discuss stochastic comparisons of two finite mixture models of different heterogeneous geometric distributions with different mixing proportions, in terms of usual stochastic, hazard rate, likelihood ratio and mean residual life orders. Finally, an application to shock models is discussed to illustrate the significance of the results established here.Article Reliability Evaluation of a System Protected by Blocks(Oxford Univ Press, 2026-04-30) Eryilmaz, SerkanWe model the reliability of a system with a main component and two auxiliary components for protection, one active, the other on cold standby. The main component performs the system function. The auxiliary components are called protection blocks. The failure rate of the main component depends on whether it is protected or not. The blocks have their own constant failure rate, that is, their lifetimes are exponentially distributed. The reliability of such a system is obtained and the properties of its failure rate are investigated. A necessary condition is obtained to compare the cost-effectiveness of single and two-block protection. Likewise, we obtain necessary conditions for comparing the effectiveness of different three-component designs under the mean time to failure criterion. In this way, the work provides decision support for the designers of systems protected by blocks.Article Music Videos as Destination Marketing Tools: A Mixed-Method Approach Based on User-Generated Content(Routledge Journals, Taylor & Francis Ltd, 2026-05-18) Kozak, Metin; Karaca, Oktay; Sen-Kupeli, TugbaMarketing, as a dynamic concept, updates itself with the current developments both in the supply and/or demand side. The global integration of music, visual storytelling and social media is collectively about to change the marketing strategies of destinations. Therefore, this study aims to evaluate the role of music videos as audiovisual tools that shape destination image and travel intentions through the deeper analysis of user interactions and comments. Using a mixed methods design, 34,667 YouTube comments, qualitative in nature, were analysed and tested within the proposed conceptual model by conversion. As one of the pioneering empirical studies, the current study concludes that music videos are likely to attract potential visitors and improve destination image or awareness. Findings may guide improvements in upgrading the strategies to be applied for destination marketing by suggesting music videos as an effective tool and deepening the methodological perspective by converting qualitative data into quantitative metrics.Conference Object Machine Learning Outperforms Traditional Methods in Predicting Kidney Transplant Outcomes: A Multicentre Cohort Study(Wiley, 2026) Dheir, Hamad; Demir, Erol; Celtik, Aygul; Hosseini, Seyed Amir Tabatabaei; Kocak, Huseyin; Cakir, Ulkem; Sinangil, AyseArticle Improved Imputation-Type Bounds for Means of Record Values for General and Symmetric Distributions(Pleiades Publishing Ltd, 2026-03) Schmiedt, Anja B.; Balakrishnan, N.In this paper, using known values of the expectations of upper record values E(R-2), ... , E(R-m), for some m is an element of {2, ... , n - 1}, we derive improved bounds for E(R-n). Further improvements are obtained in the case of a symmetric underlying distribution. Numerical illustrations of the results are provided for the standard normal distribution. Finally, extensions of the results to k-record values are detailed.Article Global De-Democratization and Women’s Political Empowerment in the 2000s(Pergamon-Elsevier Science Ltd, 2026-07) Ertan, Senem; Keysan, Asuman ÖzgürSince 2000, democratic backsliding led to changes in the gender regime, a deterioration in gender equality, and a decline of women's empowerment demonstrated in many country studies and small-N comparisons. Given the lack of large-N cross-national analyses, this paper seeks to close the gap by examining the impact of dedemocratization on women's political empowerment by comparing 162 countries. The findings highlight that lower levels of democracy are associated with lower levels of women's political empowerment. Indeed, not only cross-national, but also within-country changes in democracy levels have substantial short-term and long-term effects on women's political empowerment. Although securing representative democracy with free political parties, free and fair elections, or an effective parliament is important to politically empower women, this study demonstrates that women's political empowerment is sustained in countries where the rule of law and participatory democratic rule are strongly consolidated.Article Frequency Effect on Electrical and Dielectric Characteristics in InSe-Interlayered MOS Device(Springer, 2026-05) Emir, C.; Sahin, Y.; Ozkara, B.; Erkutlu, N.; Koc, E.; Ocak, S. Bilge; Tataroglu, A.In current study, the electrical and dielectric properties of the metal/oxide/semiconductor (MOS) structure formed with an InSe thin film layer grown by thermal evaporation were investigated over the voltage range of +/- 4 V and frequency range of 1 kHz to 1 MHz. Admittance analysis Y = G + jwC was performed for electrical measurements. Dielectric parameters were derived from the electrical measurement results. The density of states/traps were calculated employing both the Hill-Coleman and low-high frequency capacitance (C-LF-C-HF) methods is consistent with each other, and its decrease with increasing frequency is a result of the surface passivation effect. The series resistance reduces with increasing frequency. Dielectric constant and loss decrease with increasing frequency due to the effect of different polarization mechanisms. oacis independent of frequency in the low frequency region but exhibits a linear increase at high frequency region. The results obtained highlight that the fabricated MOS structure shows potential for storage devices, which are an integral part of electronic circuits and applications.
