Research on Evaluator Education and Training: Conceptual and Practical Bounds for a Scholarship of Teaching and Learning (SoTL)

New Directions for Evaluation, Volume 2025, Issue 187, Page 59-66, Fall 2025.
ABSTRACT In this article, we contextualize research on evaluator education and training (RoEET) within its historical context by grounding it in a RoE framework posed by Mark and a landscape analysis by King and Ayoo. We then link RoEET with contemporary views on philosophical, applied, and empirical dimensions of the scholarship of teaching and ...

Random Matrix Theory-Based Reduced-Dimension Space-Time Adaptive Processing under Finite Training Samples

Remote Sensing, 2022
Space-time adaptive processing (STAP) is a fundamental topic in airborne radar applications due to its clutter suppression ability. Reduced-dimension (RD)-STAP can release the requirement of the number of training samples and reduce the computational ...

Anti-jamming method for STAP based on a bi-phase random-coded signal

The Journal of Engineering, 2019
The scattered-wave sweeping frequency jamming occupies many space-time adaptive processing (STAP) degrees of freedom, which results in a serious decline in STAP performance. To solve this problem, an anti-jamming method of STAP based on a bi-phase random-

Optimizing the number of players and training bout durations in soccer small‐sided games: Effects on mood balance and technical performance

European Journal of Sport Science, Volume 25, Issue 3, March 2025.
Abstract This study aimed to determine the effects of different bout durations (1 × 12 min, 2 × 6 min and 3 × 4 min) of three‐a‐side (3vs3) and four‐a‐side (4vs4) small sided games (SSGs) with goalkeepers, on the profile of mood state (POMS) scores, and technical performance (percentage of successful passes, percentage of successful tackles, percentage

Anti-jamming techniques for multichannel SAR imaging [PDF]

, 2004
An airborne broadband jammer present in the mainbeam of a Synthetic Aperture Radar (SAR) can potentially destroy a large region of the SAR image. In addition to this, multipath reflections from the ground, known as hotclutter or terrain scattered ...
