‘Mere Amateurs’? Elementary Teachers and the Making of Scientific Authority in the British Child Study Movement

History, EarlyView.
Abstract This article offers new perspectives on the relationship between elementary teaching, scientific expertise and the professionalization of the human sciences. Previous scholarship has demonstrated the ready existence of ‘amateur’ science societies in the nineteenth century where cross‐class exchanges were common.

State of the Field: Royal Studies and Court Studies

History, EarlyView.
Abstract Monarchy, as the world's oldest and most enduring form of political organization, is an area that has attracted the attention of scholars from a range of disciplines. Two connected and complementary fields embody this interdisciplinary study of monarchy and monarchies: royal studies, which takes an all‐encompassing approach to monarchy, and ...

‘Sinister Indian‐like Half‐circle’: Tennis, Orientalism and the White Racial Frame in the Twentieth‐Century British Sporting Press

History, EarlyView.
Abstract Examining sport alongside race, media and imperial power opens a rich field for understanding how macro‐level ideologies are shaped and circulated through everyday cultural forms. In twentieth‐century Britain, mass media framed and distributed narratives that rendered the empire's political realities intelligible to a broad public.

Modeling the Hall thruster [PDF]

34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 1998
The acceleration of the plasma in the Hall thruster to supersonic velocities is examined by the use of a steady state model. Flows that are smooth across the sonic transition plane are found. The possibility of generating flows in which the acceleration across the sonic plane is abrupt, is also studied.

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.
