Pre‐task Vocabulary Support Enhances Lexical Learning but Dampens Positive Emotions: Interactive Task Implementation in English‐as‐a‐Foreign‐Language Classroom

TESOL Quarterly, EarlyView.
Abstract This classroom study explored the effects of vocabulary support on collocation learning and affective responses in task‐based language teaching (TBLT) among English‐as‐a‐foreign‐language (EFL) learners at a Japanese university. For this purpose, 68 EFL learners completed two interactive information‐gap tasks under either vocabulary‐support or ...

Bridging Leadership Development and Hip‐Hop Culture: Empowering Black Students Through Culturally Responsive Educational Approaches

New Directions for Student Leadership, Volume 2025, Issue 185, Page 89-95, Spring 2025.
ABSTRACT Hip‐hop music and culture have existed for decades in the United States. Since the 1970s, five critical elements have been defined as parts of hip‐hop culture: the MC (oral), the DJ (aural), graffiti (visual), knowledge (mental), and breakdancing (physical).

Rayleigh Instability in Hall Thrusters

38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002
Gradient-driven Rayleigh-type instabilities in Hall plasma thrusters are analyzed using linearized two-fluid hydrodynamic equations. Necessary instability conditions and a general criterion for stability of azimuthally propagating perturbations are derived.

Propellant utilization in Hall thrusters

32nd Joint Propulsion Conference and Exhibit, 1996
Fuel optimal trajectories for electrically propelled spacecraft require a varying thrust acceleration. To achieve this requirement the electric thruster has to be operated with a variable thrust to power ratio at the maximum available input power. In order to implement this operating mode with a Hall thruster it is necessary to modify both the mass ...

Computational model of a Hall thruster

Computer Physics Communications, 2004
Correctly modelling the transverse electron mobility is a principle difficulty in computational modelling of Hall thrusters. A 2D hybrid PIC-MCC model is used to test two different electron mobility models. The two models, one based on Bohm diffusion and the other on electron-wall collisions, are applied to two different Hall thrusters (SPT-100 and UM ...
