Early relational health during the first 24 months of life is a key determinant of child development and wellbeing. During this postnatal period, the parent–infant relationship plays a central role in emotional regulation, bonding, and developmental trajectories. Although the broader early relational health framework encompasses the first 1,000 days of life, this scoping review focuses specifically on the postnatal phase, where parent–infant interactions are directly observable and measurable. However, existing assessment instruments vary widely in their conceptual focus, scope, and characteristics, and no comprehensive review has systematically mapped tools used to assess the parent–infant relationship during early infancy. In response to this gap, a transdisciplinary working group within the COST Action CA22114 – TREASURE collaboratively developed a scoping review protocol to systematically map instruments assessing the parent–infant relationship from birth to 24 months of age. This Brief Report describes the collaborative methodological process underpinning the protocol’s development. The process followed an iterative, consensus-driven approach involving multidisciplinary experts from multiple COST member countries. Through structured online meetings, the group clarified core constructs and established the age range using the Population–Concept–Context (PCC) framework. The JBI methodology for scoping reviews was adopted and aligned with PRISMA-ScR standards to ensure transparency and reproducibility. Progressive drafting, internal peer review, and iterative refinement led to the final protocol, which was registered on the Open Science Framework (DOI: https://doi.org/10.17605/OSF.IO/HRVX9 10.17605/OSF.IO/HRVX9).The resulting protocol provides a replicable methodological framework for mapping instruments that assess the parent–infant relationship in the first two years of life. This Brief Report presents a framework for collaborative protocol development in international research networks, promoting shared knowledge generation in early relational health research and offering potential applicability to other COST initiatives.
Integrated Regime-Aware Wind Power Forecasting using Multi-Altitude Meteorological Features and Hybrid Machine Learning
(Frontiers Media SA, 2026) Işık, Murat; Yalçınkaya, Mehmet Ali
Accurate wind power forecasting is critical for grid stability and renewable energy integration, yet the inherent variability of atmospheric conditions presents significant challenges. This study proposes a unified and scalable pipeline that integrates wind regime detection, temporal sequence modeling, and regime-conditioned deterministic and probabilistic power forecasting. Using 8 years of high-resolution meteorological data from multiple altitudes, we engineer a comprehensive set of physically interpretable features, including wind shear, temperature gradients, and rolling statistics. Regimes are identified via KMeans and Gaussian Mixture Models, with Principal Component Analysis applied post-clustering for visualization and interpretation. Temporal regime dynamics are characterized through both empirical and Markov transition matrices and modeled using Long Short-Term Memory (LSTM) networks for regime sequence prediction. For power forecasting, regime-specific models are developed using tuned ensemble regressors (XGBoost, LightGBM, CatBoost, and Random Forest), complemented by probabilistic approaches including Quantile Regression Forests, quantile-based XGBoost, and Bayesian neural networks. Results show that regime conditioning significantly enhances forecasting performance, with the stacked meta-learning ensemble achieving R2 = 0.997 and over 30% reduction in MAE compared to baseline methods. Probabilistic models produce well-calibrated prediction intervals, providing uncertainty-aware forecasts suitable for operational decision-making. This work contributes a novel end-to-end framework that jointly models regime persistence, transitions, and regime-conditioned power output, incorporating uncertainty quantification through Quantile Regression Forests, quantile-based XGBoost, and Bayesian Neural Networks, thereby bridging a gap in the literature where these components are often treated in isolation. The approach advances both accuracy and interpretability, offering practical value for wind farm operation and renewable energy integration.
Investigation into the Reprocessability of Polycarbonate/Organoclay Nanocomposites
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Tuna, Başak
With the rapid expansion in the use of nanomaterials, ensuring their reprocessability has become a critical consideration for the sustainable development of polymer-based nanocomposites. In this study, the effects of repetitive thermo-mechanical processing cycles on the properties of polycarbonate (PC)/organoclay nanocomposites, as well as the impact of reactive extrusion of reprocessed PC/organoclay nanocomposites using a chain extender, were investigated for the first time. The nanocomposites were processed three times using a twin-screw extruder, and a multi-anhydride functional chain extender was incorporated to counteract the thermo-mechanical degradation observed after the third extrusion cycle. Morphological analysis indicated that the delamination of clay nanolayers within the polymer matrix was slightly enhanced with increasing extrusion cycles, while the addition of the chain extender further promoted nanoclay exfoliation. Despite the improved clay dispersion in PC, both rheological and tensile measurements revealed the detrimental effects of repeated reprocessing on the nanocomposites. The chain extender effectively mitigated this degradation by relinking cleaved polymer chains; consequently, the complex viscosity and storage modulus at 0.1 Hz of the three-times-extruded nanocomposite increased by 248% and 426%, respectively, following chain extender incorporation. The effectiveness of the chain extender was further evidenced by a 27% enhancement in tensile strength. The glass transition temperatures of the samples were not significantly affected by either the extrusion cycles or the addition of the chain extender. The thermal stability of the nanocomposites decreased with increasing numbers of extrusion cycles; however, the incorporation of the chain extender imparted enhanced resistance to thermal degradation, as confirmed by thermogravimetric analysis.
Developing and Validating The Deadly Habits in Marriage Scale: A Choice Theory-Based Measure of Destructive Relational Behaviors
(Springer, 2026) Kurt, Dilek Gençtanırım; Çetin, Sevda; Kargı, Tunahan; Demir, Ziya
This study developed and validated the Deadly Habits in Marriage Scale (DHMS), a Likert-type scale grounded in Choice Theory, which posits that behaviors are self-determined to meet innate psychological needs (e.g., love, power, freedom). Deadly habits—destructive behaviors stemming from external control psychology—undermine marital relationships. Using two independent samples of married individuals in Türkiye (N = 483; N = 314), the DHMS was developed in Turkish through item generation, content validation, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability assessment, and criterion-related validity evaluation. From an initial 45-item pool, EFA identified a five-factor structure—criticizing, blaming, complaining, threatening, and punishing—collapsing seven theoretical habits (including nagging and rewarding to control) into 37 empirically validated items due to overlapping behavioral patterns (e.g., nagging merged with complaining). CFA confirmed this structure, with internal consistency coefficients ranging from 0.74 to 0.90 for subscales and 0.94 overall. The DHMS showed convergent and discriminant validity and negative correlations with marital satisfaction (r=-0.43, p < 0.001) and dyadic trust (r=-0.54, p < 0.001). This reliable and valid tool assesses destructive relational patterns in Turkish marriages, offering applications in clinical practice, marital counseling, and social psychology research. Its potential for cross-cultural adaptation enhances global relevance, with future validation needed for diverse populations. The DHMS provides a robust framework for understanding and addressing maladaptive behaviors in marriage, advancing Choice Theory’s empirical application.
Pierres Errantes: Two Latin Inscriptions transported from the Docimium Quarries to Istanbul
(Phaselis Research Station, 2025) Di̇nç, Senem
This study presents two Latin inscriptions currently exhibited in Sanatçılar Parkı in Ataköy, Istanbul, which originally belonged to the Roman Imperial marble quarries of Docimium (modern Iscehisar, Afyon). One of the inscriptions was previously discovered in the Bacakale sector of the Docimium quarries and was published in 1991. Although the other inscription remains unpublished, it was most likely brought to Istanbul together with the former piece. After situating these fragments within the broader corpus of quarry inscriptions, they are re-examined here in light of the earlier studies by J. C. Fant, M. Christol, and Th. Drew-Bear, with particular attention to their epigraphic and historical contexts. The inscriptions illustrate the use of standard abbreviations designating quarry sections (bracchium, locus), the workshop engineer (officina), and the quarry engineer (caesura), thereby providing evidence for the complex bureaucratic system that regulated production and transport. The paper also addresses the transfer of these inscriptions to Istanbul, while expressing concerns about the ongoing threats that modern quarrying activities pose to archaeological evidence.
