From Negative Evidence to Learning Opportunities: Investigating Informal Formative Assessment Practices in an L2 Classroom
No full textThis study investigates teachers’ informal formative assessment (IFA) signalled by negative evidence in classroom interactions. In this single-case study, we examined classroom recordings of a language teacher and analysed micro-moments of the interaction using Conversation Analysis (CA). Concentrating on detailed excerpts of classroom interactions, we discuss how negative evidence signals the teacher’s IFA process. We provide evidence that this process paves the way for maximising learning opportunities and shaping learner contributions in the immediate/subsequent turns of speech following a teacher’s assessment and feedback, thus underscoring the concept of Classroom Interactional Competence (CIC). By presenting insights into the interactional patterns of IFA in second language (L2) classes, our findings contribute to the growing body of research integrating assessment and classroom interaction.</p
Childbearing as Continuity and Meaning: A Mixed-Methods Study of Social and Psychological Motivations in Eastern Türkiye
No full textThis study investigates overt and latent motivations for childbearing among married individuals in southeastern Turkey—a region marked by strong patriarchal norms and economic disadvantage. Using a mixed-methods triangulation design, the research combines quantitative data from 399 participants with qualitative insights from 30 interviews. Findings show that motivations are shaped by fertility attitudes, gender, education, income, family type, and child loss. While economic value declines, children retain strong social and emotional meaning—especially as boys symbolize lineage and girls represent emotional closeness. These gendered and cultural constructs significantly influence reproductive decisions. The study underscores the need for culturally attuned fertility policies and highlights the importance of integrating social meaning into reproductive health programs in traditional communities
Exercise-Induced Regulation of Spexin: Implications for Metabolic Health: A Systematic Review and Meta-Analysis
No full textPsychosocial dimension of adolescent pregnancy: a phenomenological study on life experiences
No full textAim: This study aimed to assess the lived experiences of adolescent pregnant young women, with a specific focus on the psychosocial aspect of adolescent pregnancy, using a phenomenological approach. Design: Employing the phenomenological research method, semi-structured in-depth interviews were conducted between 3 August and 18 August 2023 with 15 young women (mean age = 21.86 years; SD = 1.06) living in a province in eastern Turkey who had undergone adolescent pregnancy 3–5 years before. Methods: The criterion sampling method, a form of purposive sampling, was used to form the sample group. Interviews were carried out until data saturation was reached. All interviews were recorded and transcribed, and thematic analysis was utilised to analyse the data. The study adhered to the COREQ checklist for reporting. Results: Through data analysis, three main categories (reflections on adolescent pregnancy, challenges due to adolescent pregnancy, and effects of adolescent pregnancy) and nine sub-themes (emotions, roles and responsibilities, perception of social support, cognitive, emotional, behavioural, mental, physical, and social) emerged. Conclusion: Our study highlights the adverse psychosocial impact of adolescent pregnancy on young women. Young women who got married at an early age before attaining full physical, social, and psychological maturity grappled with the substantial burdens of adolescent pregnancy and adjusting to their new roles. The study’s implications are significant, emphasising the necessity of addressing the psychosocial facets of adolescent marriage and pregnancy, and gaining valuable insights for the future
Optimal photovoltaic system placement on the distribution grid by applying modified honey badger algorithm in the probabilistic framework
No full textThis study presents a method that combines Monte Carlo Simulation (MCS) with Modified Honey Badger Algorithm (MHBA) for the first time to investigate the impact of photovoltaic (PV) system uncertainties on power losses under different solar radiation conditions. Moreover, this research proposes the chance – constrained probabilistic planning by generating probability distribution functions (pdf) of bus voltage and line current and taking into account probability constraints for encouraging more efficient and secure utilization of electricity. This study contributes to the information base concerning the optimal PV system placement by considering chance – constrained method. The simulation results reveal that the MHBA approach demonstrates more advantageous computational performance as compared to Differential Evolution (DE) in the IEEE 118 bus distribution system. By running both algorithms several times, MHBA method produces the best optimal power loss of 531.8649 kW in 1475.6075 s, whereas DE approach gives that of 540.9138 kW in 3373.4966 s for high radiation scenario, respectively. It has been revealed that the power loss may be further reduced by the increasing solar radiation conditions. In order to provide evidence that the proposed methodology is effective, the results of optimization are validated under different scenarios through the application of MCS. In addition, the constraints of network are investigated in order to make a determination regarding the probabilities of exceeding their limits. The validation of optimization results has concluded that the confidence levels of 0.7, 0.8, and 0.9 have been maintained for the low, medium, and high solar radiation scenarios, respectively
BaF2-doped borosilicate glasses for next-generation radiation shielding and optical applications: A hybrid experimental and computational study
No full textBaF2-doped borosilicate glasses were produced using the melt-quenching method with compositions of (56-x)B2O3 + 12SiO2 + 20CaO + 12Li2O + xBaF2 (x = 0, 2.5, 5, 7.5, and 10 mol%). The impact of BaF2 on the structural, optical, and radiation shielding characteristics was examined through experimental techniques and computational modelling. Density measurements indicated an increase from 2.2138 g/cm3 (BSCLB0) to 2.6549 g/cm3 (BSCLB10), attributed to the higher density of BaF2. Optical analysis revealed that the incorporation of BaF2 significantly altered the glass properties. The UV absorption edge shifted toward shorter wavelengths, decreasing the cut-off wavelength from 362.59 nm (BSCLB0) to 338.82 nm (BSCLB10), which suggests enhanced transparency in the UV region. The optical band gap energy for direct transitions increased from 3.835 eV to 4.145 eV, indicating a more compact glass structure. Meanwhile, the refractive index (n) declined from 1.769 (BSCLB0) to 1.558 (BSCLB10), demonstrating that BaF2 enhances optical clarity but may not be ideal for applications requiring a high refractive index. Additionally, the extinction coefficient (k) decreased, signifying reduced optical losses. The Urbach energy (EU), which reflects structural disorder, rose from 0.883 eV to 1.004 eV, implying slight modifications in the glass network due to BaF2 doping. The radiation shielding potential of BaF2-enriched borosilicate glasses was assessed using Monte Carlo simulations, EpiXS software, and Artificial Neural Networks (ANNs). The mass attenuation coefficient (MAC) exhibited a rise from 5.700 cm2/g (BSCLB0) to 17.093 cm2/g (BSCLB10) at 15 keV, indicating superior photon attenuation. Furthermore, the half-value layer (HVL) declined from 2.95 cm to 2.65 cm at 50 keV, confirming improved shielding performance. Glasses with higher BaF2 content displayed elevated effective atomic numbers (Zeff), reaching approximately 50 at 40 keV, which helps in minimizing secondary radiation generation. In terms of neutron shielding, the removal cross-section (ΣR) showed a modest increase, reaching 0.0956 cm−1 for BSCLB10, making these glasses comparable to boron carbide and graphite in neutron attenuation. These findings suggest that BaF2-doped borosilicate glasses are promising candidates for dual-purpose shielding applications, effectively attenuating both gamma rays and neutrons in nuclear and medical environments
