What are the views and experiences of autistic teachers? Findings from an online survey in the UK
Despite significant research into the education of autistic children and young people (CYP) and an increased awareness of the employment needs and rights of autistic adults, little attention has been paid to autistic teachers. We discuss findings drawn from an online survey in the UK in which autistic teachers and other autistic education staff (n = 149) describe the lack of understanding, sensory impacts, mental health issues and the complexities associated with revealing an autism diagnosis as a result of their work. These issues can represent significant impediments to either entering or remaining in the school education profession. Positive experiences were also found and, from a social justice perspective, the possibilities of autistic school staff to constitute a role model for autistic CYP and to facilitate their educational inclusion are considered. Future directions in this under-researched area are also discussed
Videoconferencing via satellite. Opening Congress to the people: Technical report
The feasibility of using satellite videoconferencing as a mechanism for informed dialogue between Congressmen and constituents to strengthen the legislative process was evaluated. Satellite videoconferencing was defined as a two-way interactive television with the TV signals transmitted by satellite. With videoconferencing, one or more Congressmen in Washington, D. C. can see, hear and talk with groups of citizens at distant locations around the country. Simultaneously, the citizens can see, hear and talk with the Congressmen
Cartesian Bicategories II
The notion of cartesian bicategory, introduced by Carboni and Walters for
locally ordered bicategories, is extended to general bicategories. It is shown
that a cartesian bicategory is a symmetric monoidal bicategory
An overview of the fundamental aerodynamics branch's research activities in wing leading-edge vortex flows at supersonic speeds
For the past 3 years, a research program pertaining to the study of wing leading edge vortices at supersonic speeds has been conducted in the Fundamental Aerodynamics Branch of the High-Speed Aerodynamics Division at the Langley Research Center. The purpose of the research is to provide an understanding of the factors governing the formation and the control of wing leading-edge vortices and to evaluate the use of these vortices for improving supersonic aerodynamic performance. The studies include both experimental and theoretical investigations and focus primarily on planform, thickness and camber effects for delta wings. An overview of this research activity is presented
Experimental performance of a 13.65-centimeter-tip-diameter tandem-bladed sweptback centrifugal compressor designed for a pressure ratio of 6
A 13.65 cm tip diameter backswept centrifugal impeller having a tandem inducer and a design mass flow rate of 0.907 kg/sec was experimentally investigated to establish stage and impeller characteristics. Tests were conducted with both a cascade diffuser and a vaneless diffuser. A pressure ratio of 5.9 was obtained near surge for the smallest clearance tested. Flow range at design speed was 6.3 percent for the smallest clearance test. Impeller exit to shroud axial clearance at design speed was varied to determine the effect on stage and impeller performance
