Embracing the Future: An Investigation into Teacher Educators' Acceptance of Generative AI in Educators Preparation Programs

This study explored teacher educators' acceptance and perceptions of using generative artificial intelligence (GenAI) in their practices, particularly with preservice teachers. Guided by the Technology Acceptance Model Plus Plus (TAM++), this study utilized a comprehensive survey...

Enjoyment and Engagement in AI ‐Mediated Informal Digital Learning of English: A Latent Growth Curve Modelling Study

ABSTRACT Enjoyment and engagement are critical for effective language learning, yet little is known about how these experiences evolve over time in AI‐mediated informal digital English learning (IDLE). Previous studies have mainly relied on cross‐sectional designs, limiting under...

Assessment of social distance toward refugees and related factors among prehospital emergency health care providers

Objective: Social distance towards refugees among health care providers reflects how refugees benefit from health services and empathy, acceptance, and discrimination. Social distance is crucial for Pre-Hospital Emergency Health Care Providers (PHEHCP), who are the first group to...

Comparison of Inoculation Routes for Honeybee Gut Microbiota Assembly Under Laboratory Conditions

The honeybee (Apis mellifera) gut microbiota serves as a model for host–microbe studies, as newly emerged workers provide a low-complexity, nearly germ-free system. Although multiple inoculation strategies are commonly applied under laboratory conditions, their comparative effect...

Towards An In-Situ Capable Method For Measuring Thermal Barrier Coating Thermal Resistance By Induction Phase Radiometry: Experimental Benchtop Demonstration

Abstract This study introduces an in-situ approach to measuring the thermal resistance of thin ceramic coatings deposited on metallic substrates using induction phase radiometry. A one-dimensional analytical heat-transfer model is formulated that relates the phase lag between per...

Undecidability in Quantum Measurement and Separability Surpasses Classical Limits — E8 Intelligence Research

**FINDING:** Undecidability extends to quantum measurement occurrence and separability, revealing a deeper computational limit than classical analogues. **MATH:** No explicit equations or constants derived; core result is that the decision problem "Does a given quantum circuit pr...

Comparative Life Cycle Assessment of Conventional Type IV and Additively Manufactured Hydrogen Pressure Vessel

The transportation sector is a major contributor to global greenhouse gas emissions, driving the need for low-carbon energy solutions. Hydrogen is increasingly recognised as a promising option for decarbonising heavy-duty and long-distance transport; however, hydrogen storage sys...

Supply Chain Resilience and Total Factor Productivity: Evidence from Listed Manufacturing Firms

Background: Manufacturing productivity increasingly depends on reliable interorganizational flows, yet supply chain disruptions can interrupt materials, information, finance, and efficient use of productive inputs. Although supply chain resilience is widely treated as a continuit...

Outcomes of second-generation transoral incisionless fundoplication in a Mediterranean cohort: a retrospective study of the first Turkish experience with typical and extraesophageal gastroesophageal reflux disease symptoms

Performance and Economic Boundary Analysis of an Integrated PV–Solar-Thermal–Battery–Hydrogen System for a Cold-Climate Dwelling: A Case Study in Northern Japan

Cold-climate dwellings can face coincident electricity and domestic hot-water shortfalls in winter, when solar availability is at its lowest. This study evaluates an integrated residential system for Aomori, Japan, combining photovoltaics, evacuated-tube solar water heating, and...

ASSET-LIGHT HYBRID SUKUK: LESSONS FROM INTERNATIONAL MARKETS FOR PAKISTAN'S RIBA-FREE ECONOMIC TRANSFORMATION

The role of Global Practices and Regulatory Readiness in Market Development and Riba Transformation in the context of Asset Light Hybrid Sukuk has been examined in this study and the moderating effect of Institutional Support has been analyzed in this study. A cross-sectional des...

Interrogating Learner Progression Policy in South African Schools Through Teachers’ Perspectives

Learner progression policy in South Africa is intended to promote inclusive education by reducing grade repetition and preventing learner dropout, yet its implementation remains contested, particularly in under-resourced schooling contexts. Drawing on teacher agency and socio-eco...

DETERMINATION OF POTENTIAL LOCATIONS FOR SETTLEMENT DEVELOPMENT BASED ON LAND CARRYING CAPACITY USING CELLULAR AUTOMATA (Case Study: Karangnunggal Subdistrict)

<ns5:p>Abstract Background Karangnunggal has been designated as the prospective capital of the Proposed New Autonomous Region of South Tasikmalaya Regency, a status expected to accelerate population growth and settlement land demand in an area that remains prone to landslides and...

{167--83. \\Spectral Structure and Zeros of the Symmetrized Difference Function $I(s)$}

The central object of this paper is the symmetrized difference function: I(s) = zeta(s)/s - zeta(1-s)/(1-s) initially defined for Re(s) in (0,1). Our approach consists in: Constructing I(s), that is, deriving it from a single foundational integral representation (Riemann's formul...

Physical Interaction Through Non-Intervention: A Process-Regulation Framework for When Embodied AI Should Act, Defer, or Deliberately Remain Physically Inactive

Embodied artificial intelligence is commonly evaluated by what it can perceive, plan, and do. Human-robot interaction research, however, increasingly shows that capability is not sufficient: an agent must also determine when action would interrupt a human, when assistance can be...

Measuring masses of transiting Earth-like planets: first insights from the PLATO RV Data Challenge

Abstract The PLATO Stellar Variability Mitigation Working Group designed a radial-velocity (RV) data challenge to assess the precision and accuracy achievable on RV semi-amplitudes in the context of the future PLATO follow-up. Using Sun-as-a-star observations obtained with HARPS-...

Stigma management, social support, and quality of life among adults with Crohnʼs disease and ulcerative colitis in Saudi Arabia: A cross-sectional study
