Protocols for Integrity Constraint Checking in Federated Databases [PDF]

, 1996
A federated database is comprised of multiple interconnected database systems that primarily operate independently but cooperate to a certain extent. Global integrity constraints can be very useful in federated databases, but the lack of global queries ...

Development and evaluation of artificial intelligence literacy training for teacher education students

British Journal of Educational Technology, EarlyView.
Abstract Teacher education students play double role as present learners and future educators. Hence, they need targeted training to navigate the growing influence of Generative Artificial Intelligence (GenAI) on teaching, learning and professional identity.

High-Q distributed-Bragg-grating laser cavities [PDF]

, 2011
Applying Bragg gratings in Al2O3 channel waveguides, we demonstrate distributed Bragg reflectors with Q-factors of 1.02x10e6. An integrated Al2O3:Yb3+ waveguide laser with 67% slope efficiency and 47 mW output power is achieved with such ...

Collaborative co‐design in action: Reimagining teacher professional development for crisis‐affected contexts

British Journal of Educational Technology, EarlyView.
Abstract This paper focuses on the opportunities and challenges of conducting implementation research when co‐design is central to the project being implemented. A participatory co‐design methodology is proposed to evaluate the co‐design and implementation aspects of a teacher professional development course.

Design‐based implementation research for digitally enabled education reform: Teacher professional development in Tanzania

British Journal of Educational Technology, EarlyView.
Abstract Design‐based implementation research (DBIR) offers a promising approach for refining and theorising the implementation and scale‐up of education interventions. However, integrating technology into national education reforms in resource‐constrained contexts adds complexity, involving multiple government bodies, implementers and researchers with
