In minority educational contexts, however, students' psychological need satisfaction is also shaped by broader sociocultural conditions that may create additional pressures and sources of chronic stress. Within such environments, parental support may function as a protective factor that helps students cope with educational and cultural demands. Objective: The aim of this study was to explore how parental support contributes to the satisfaction of students' basic psychological needs within a minority educational context where students from the Greek minority attend a bilingual school operating within a Turkish educational framework. Methods: A qualitative design was employed using three focus groups conducted in a minority school located in Gökçeada, Türkiye: one with parents (N = 5), one with lower secondary school students (N = 6), and one with upper secondary school students (N = 6). Interview questions were developed on the basis of Basic Psychological Needs Theory. Data were analyzed thematically by five members of the research team. Results: Findings indicated that parental support influenced students' need satisfaction through practices related to autonomy (e.g., trust, space for mistakes), competence (e.g., encouragement, comparison), and relatedness (e.g., emotional presence, empathy). However, these practices were not experienced in a uniform way. Rather, their meaning and impact were shaped by contextual conditions associated with minority status, including bilingual educational demands, limited resources, and close-knit community dynamics. Conclusions: The study suggests that in minority school settings, parental support operates not simply as a general interpersonal resource but as a contextually mediated protective process. By showing how sociocultural and institutional conditions shape the enactment and experience of autonomy, competence, and relatedness, the findings extend existing BPNT research beyond majority settings and offer a more context-sensitive understanding of students' psychological need satisfaction.Article Psychological Intimate Partner Violence Across Identities: Preliminary Psychometrics of the Multidimensional Measure of Emotional Abuse-Short Form Among Heterosexual, Lesbian, and Bisexual Samples in Türkiye(ARCHIVES OF SEXUAL BEHAVIOR, 2026-03-01) Toplu- Demirtaş, Ezgi; Zurnaci, Burcu; Demirtaş, Ezgi TopluPsychological intimate partner violence (IPV) affects individuals across diverse sexual identities and is often reinforced by romantic myths. Despite its substantial mental health consequences, psychological IPV remains under-recognized and insufficiently researched. One barrier is the scarcity of brief, inclusive, and psychometrically sound tools for assessing psychological IPV across varied populations. To address this gap, the present study aimed to validate the short form of the Turkish version of the Multidimensional Measure of Emotional Abuse (MMEA-TR). This 16-item scale evaluates four subdimensions of psychological IPV (Restrictive Engulfment, Denigration, Hostile Withdrawal, and Dominance/Intimidation) while preserving the original multidimensional framework. Data were collected from four independent samples in T & uuml;rkiye: Bisexual individuals (n = 230, M = 22.88, SD = 4.49), predominantly heterosexual women (n = 237, M = 24.30, SD = 2.51), lesbian and bisexual women (n = 178, M = 29.06, SD = 7.81), and predominantly heterosexual men (n = 160, M = 24.49, SD = 2.54). Confirmatory factor analyses across samples supported the hypothesized four-factor model and demonstrated acceptable fit indices. Subscales showed significant intercorrelations and concurrent validity was supported by theoretically consistent associations with jealousy (Study 1), anxious attachment (Study 2), internalized heterosexism (Study 3), and fragile masculinity (Study 4). Internal consistency reliability ranged from acceptable to high across groups. Overall, findings provide initial evidence for the construct validity, concurrent validity, and reliability of the MMEA-TR short form. This study contributes a brief, inclusive, and psychometrically robust instrument for assessing psychological IPV in both heterosexual and sexual minority populations.Article Longitudinal Norms of Frailty Measured by the Frailty Index: A Cross-National Comparison Using Data from the Survey of Health, Aging, and Retirement in Europe (SHARE)(Elsevier, 2026-06-01) Gutierrez, Angela; Supiyev, Adil; Muniz-Terrera, Graciela; Sevi, Baris; Massa, Fernando; Marroig, AlejandraBackground: Frailty, a geriatric syndrome commonly used to identify vulnerable older adults, is a public health priority. However, the lack of cross-national comparisons of frailty trajectories and their distribution constrains current understanding of normative changes in frailty for residents across different countries. Objective: To derive longitudinal percentiles of frailty using a consistent cross-country approach. Design: Observational study using longitudinal data from the Survey of Health, Ageing and Retirement in Europe (SHARE) between 2004 and 2020. Setting: We fit the distribution of the FI by Generalized Additive Models for Location, Scale, and Shape (GAMLSS), assessed the role of sex (male/female), education (in years), and migration status (migrant/non-migrant), and estimated the longitudinal percentiles of frailty using a consistent cross-country approach for 16 countries. Participants: Individuals aged >= 65 years (N = 42,951) at study entry. Measurements: Frailty index (FI) based on the accumulation of deficits in 40 items. Results: The results show that education is protective against frailty in all countries (a decrease of 1.1 pp. in Switzerland to 5.7 pp. in Slovenia, all p < 0.001). In most countries, women are frailer than men and migrant individuals have higher levels of frailty than non-migrants. FI trajectories showed heterogeneity across countries. The quantiles for women and migrants suggest frailer trajectories than men and non-migrants respectively. Conclusions: Findings from this cross-national comparison provide a framework within which the longitudinal norms of frailty trajectories from different countries can be interpreted.Article Robust HMM-Based Remaining Useful Life Estimation Using a Ridge-Regularized EM Algorithm(MDPI, 2026-02-18) Kucukdag, Halime Beyza; Kirkil, Gokhan; Hekimoglu, MustafaEstimating the remaining useful life (RUL) of engineering systems is crucial for maintenance planning and the reliability of complex mechanical units. Accurate RUL predictions support timely interventions and help to prevent unexpected failures. This study proposes a statistically robust framework that models degradation signals up to the end of life using a hidden Markov model (HMM) with a simple-failure structure and an absorbing terminal state. The proposed method estimates state-dependent linear emission parameters and transition probabilities using a ridge-regularized expectation-maximization (EM) algorithm. The ridge penalty stabilizes slope estimates under limited data, while a robust Huber-based scale estimator reduces sensitivity to outliers in the sensor-derived health indicator. RUL is computed as a weighted expected time to absorption, combining transient-state survival characteristics with smoothed posterior-state probabilities obtained via the forward-backward algorithm. This yields a low-variance state-aware estimator that preserves the probabilistic structure of the HMM. Simulation studies show that the proposed ridge-regularized EM significantly reduces parameter variance and improves predictive accuracy compared with the baseline weighted least squares EM (WLS-EM). A real-data case analysis demonstrates further improvements in RUL estimation accuracy and smoother, more reliable prediction trajectories. Overall, the framework provides a robust and interpretable approach for practical prognostics applications.Article Citation - WoS: 3Citation - Scopus: 6Cross-Cultural Data on Romantic Love and Mate Preferences From 117,293 Participants Across 175 Countries(Nature Research, 2025-07-01) Kowal, Marta; Sorokowski, Piotr; Gjoneska, Biljana; Pisanski, Katarzyna; Pfuhl, Gerit; Aguilar, Leonardo; Prazeres, Filipe; Toplu-Demirtaş, EzgiPsychological studies on close relationships have often overlooked cultural diversity, dynamic processes, and potentially universal principles that shape intimate partnerships. To address the limited generalizability of previous research and advance our understanding of romantic love experiences, mate preferences, and physical attractiveness, we conducted a large-scale cross-cultural survey study on these topics. A total of 404 researchers collected data in 45 languages from April to August 2021, involving 117,293 participants from 175 countries. Aside from standard demographic questions, the survey included valuable information on variables relevant to romantic relationships: intimate, passionate, and committed love within romantic relationships, physical-attractiveness enhancing behaviors, gender equality endorsement, collectivistic attitudes, personal history of pathogenic diseases, relationship quality, jealousy, personal involvement in sexual and/or emotional infidelity, relational mobility, mate preferences, and acceptance of sugar relationships. The resulting dataset provides a rich resource for investigating patterns within, and associations across, a broad range of variables relevant to romantic relationships, with extensive opportunities to analyze individual experiences worldwide. © The Author(s) 2025.
