Öğe Türü: Öğe , Artificial Intelligence Research in School Leadership and Management: A Text Mining-Based Computational Literature Review and Future Directions(Frontiers Media SA, 2026) Karaköse, Turgut; Kaptan, Orhun; Kılıç, Gülenay Nagihan; Kocabaş, İbrahim; Yirci, RamazanAs artificial intelligence (AI) becomes increasingly embedded in school leadership and management literature, it is important to understand not only which themes are emerging, but also how coherent, mature, and distinct these themes have become. To address this need, this study conducted a text-mining-based computational literature review of 112 articles published between 2021 and 2026. The corpus was analyzed through three complementary procedures: Structural Topic Modeling (STM), conceptual maturity analysis, and semantic network fragmentation analysis. The STM analysis yielded five thematic axes: AI readiness, adoption, and self-efficacy; ethical and data-informed AI decision-making; AI literacy and digital leadership; teacher leadership and distributed agency in AI-integrated teaching; and governance frameworks for ethical and human-centered AI leadership. Ethical and data-informed decision-making exhibited the highest expected topic proportion and conceptual maturity, while AI readiness and adoption displayed moderate maturity and temporal continuity. By contrast, AI literacy and digital leadership, teacher leadership and distributed agency, and human-centered governance remained less consolidated. The semantic network analysis indicated that, within the controlled concept dictionary, the selected core concepts formed a connected co-word structure rather than a fully fragmented one; however, this pattern is interpreted as semantic convergence among dictionary-defined concepts rather than as evidence of complete theoretical integration. Future research should therefore strengthen conceptual and empirical work on these emergent themes, while extending mature themes through longitudinal, comparative, and intervention-oriented designs.Öğe Türü: Öğe , Assessing State Support for MSMEs in Azerbaijan: Evidence from Concessional Lending (2020-2024)(Visagaa Publishing House, 2026) Mammadova, S.M.; Musayev, Y.E; Huseynov, P.F.; Taghiyev, A.A.; Huseynzade, A.N.This study assesses state support for MSMEs in Azerbaijan by examining concessional lending and its relationship with selected macroeconomic indicators during 2020–2024. The analysis is limited to five observations because pre-2020 MSME indicators were compiled under a different methodology, while 2024 is the latest year with comparable official data. Using descriptive analysis, indexed trends, and Pearson correlations of logarithmically transformed variables, the study identifies strong positive co-movement between concessional lending and MSME value added (r = 0.9278). Concessional lending more than doubled and MSME value added rose by 93%, whereas fixed-capital investment peaked in 2022 and fell below its 2020 level by 2024. The MSME share of GDP declined to 12.8% in 2022 before recovering to 16.8% in 2024. Sectoral structure remained stable in 2023–2024. Given the limited observations, the correlations are interpreted descriptively rather than causally, highlighting the importance of investment dynamics and sectoral structure in assessing state support.Öğe Türü: Öğe , BSN. VIII. Detailed Photometric Modeling of Ten W UMa Contact Binaries and a Revised Empirical Period–Mass Relationship(Institute of Physics, 2026) Poro, Atila; Jafarzadeh, S. Javad; Li, Kai; Coliac, Jean-François; Baudart, Sabrina; Guo, Meng; Wullaert, Patrick; Valls-Gabaud, David; Ben Lassoued, Anis; Verilhac, Daniel; Corp, Laurent; Foguenne, Emmanuel; Lerat, Hervé; Marquette, Jean-Baptiste; Vasseur, Serge; Lekic, Anica; Alicavus, Fahri; Alan, NeslihanThis study continues our ongoing research on contact binary systems by presenting a detailed analysis of 10 targets. Ground-based observations from six different observatories were conducted and used together with TESS data for the analysis process. Photometric data from our observations were reduced with the recently developed AutoWISP pipeline, yielding high-quality light curves with reliable precision for analysis. An investigation of orbital period variations identifies long-term trends in six of the ten analyzed binaries, including three that also display cyclic variations. Four targets show essentially constant orbital periods. The secular trends are attributed to mass transfer. The cyclic modulations in three systems are caused by either magnetic activity cycles or the Light-Travel Time Effect (LTTE) of a third body, while that in the remaining system is solely due to the LTTE. The BSN application was used to model the photometric light curves of the 10 target binaries. Iterative fitting and MCMC refinement provided robust estimates of the system parameters, while starspot modeling was applied for systems showing O’Connell-effect asymmetries. We refine the empirical orbital period–mass relationship for short-period contact binaries by analyzing a homogeneous data set of systems and deriving an updated primary-mass calibration based on the spectroscopic subset. Using this calibrated relation, the fundamental parameters of the studied systems were subsequently estimated.Öğe Türü: Öğe , BSN-VII: Photometric Light Curve Study of Three Cool, Large-amplitude, Low Mass, W-Subtype Contact Binaries(Institute of Physics, 2026) Poro, Atila; Michel, Raul; Zadkhosh, Diana; Fard, Ava Ekrami; Sangdehi, Kian Farhadi; Lekic, Anica; Cellier, Maxime; Da Graca Baptista, Chloé; Pointier, Paul; Aliçavuş, Fahri; Sarvari, Elham; Alan, NeslihanWe present a comprehensive photometric study of three W UMa-type contact binary systems, V1104 Her, V1284 Her, and V2822 Ori, based on a combination of ground-based observations and space-based TESS photometry. The light curves were modeled using the BSN application under a contact configuration, with parameters and their uncertainties estimated through the Markov Chain Monte Carlo (MCMC) approach. The derived solutions indicate that the target systems are in a shallow-contact configuration. The target systems are classified as W-subtype contact binaries, with the more massive component cooler than its companion. The light curve of V1284 Her shows a pronounced O’Connell effect, which is reproduced by introducing a cool starspot on the primary component. Absolute parameters were estimated using the empirical parameter relationship between orbital period and semi-major axis, yielding component masses in the range 0.48–0.86 M⊙ and confirming the low-mass nature of the systems. Orbital period variations were investigated using eclipse timings from the literature, ground-based observations, and TESS data by examining both linear and cyclic models. Statistical model comparison indicates that the cyclic model provides a better description of the eclipse timings for V1104 Her and V1284 Her, whereas the linear model is preferred for V2822 Ori, although the difference between the two models is relatively small.Öğe Türü: Öğe , In Situ EBSD Characterization of Static Recrystallization in a Mg-Zn-Ca (ZX30) Alloy(KeAi Communications Co., 2026) Saraç, Abdülhamit; Berman, Tracy; Venkatesh, Varun S.; Shahani, Ashwin J.; Allison, John; Bucsek, AshleyThe recrystallization behavior of a hot-compressed Mg–3Zn–0.1Ca (ZX30) alloy during static recrystallization was investigated in situ using electron backscatter diffraction (EBSD). The material was subjected to 5% plane-strain compression at 200 °C, and subsequently exposed to successive annealing treatments at 300 °C using a heating stage integrated with a scanning electron microscope (SEM)–EBSD system. The microstructural evolution and recrystallization process were monitored by performing EBSD scans immediately after each annealing step. Within this framework, three questions were addressed: (i) whether recrystallized grains can be reliably identified and quantified using EBSD metrics, (ii) whether recrystallized grains nucleate preferentially at grain boundaries, twin boundaries, or triple junctions, and (iii) whether grains with a Grain Orientation Spread (GOS) below 1 ° accurately represent the recrystallized fraction. Recrystallized grains were identified using grain-neighborhood, centroid, and orientation information through a graph-based approach. At the end of the process, the cumulative recrystallized grain area accounted for 28% of the total grain area. The analysis revealed that initially, approximately 70% of the recrystallized grains nucleated adjacent to twin boundaries, with this fraction gradually decreasing as the twin fraction decreased from an initial 15%. 36% of the recrystallized grains not adjacent to twin boundaries were initially observed to form at triple junctions. GOS maps indicated that many grains exhibited GOS values below 1 ° without undergoing recrystallization, exhibiting only recovery and growth. For the ZX30 alloy deformed to a low strain level (5%) at 200 °C, the present study reveals that the area fraction of grains with GOS below 1 ° could not be used as the sole metric for quantifying the recrystallized fraction. The total number of recrystallized grains as a function of the angle between the c-axis and the normal direction (ND) was determined, revealing a weakening of the basal texture for the annealed ZX30 alloy.
