No full textElizabeth Lynn Ray is the Vice President, Mission Support Services for the Air Traffic Organization (ATO) in the Federal Aviation Administration. Mission Support includes various FAA headquarters programs responsible for the rules, policies, and standards for airspace structure, design and allocation; obstruction evaluation; air traffic environmental policy; the design and implementation of area navigation/required navigation performance procedures; the development of air traffic procedures and standards; the production and charting of instrument flight procedures; the development and validation of Air Traffic concepts and requirements; and aeronautical information management. In addition, Mission Support includes the ATO service centers in Atlanta, Dallas, and Seattle. The service centers provide staff support to the Directors of Operation in airspace and procedures, quality assurance, equipment installation and program management, and business and administrative services.
Ray joined the Federal Aviation Administration in 1984, beginning her career as an air traffic control specialist at the Atlanta Air Route Traffic Control Center where she held several positions including that of air traffic manager. She also held a variety of FAA regional office and headquarters positions. In 2007, Ray was selected for assignment to the Joint Planning and Development Office (JPDO) as the Government lead for the Air Navigation Services Working Group as part of the partnership to deliver the Next Generation Air Transportation System. Ray held that position until December 2008 when she was selected as a member of the FAA Executive System as the Director of System Operations Airspace and Aeronautical Information Management in the ATO. She was selected as the Vice President, Mission Support Services in November 2010.
Ray holds a B.S. (with honors) in biology from Milligan College; an M.S. in zoology from the University of South Florida; and a J.D. (with honors) from Georgia State University College of Law. She was admitted to the Georgia Bar in 2001. Ray is also a member of the Air Traffic Control Association and Professional Women Controllers.https://commons.erau.edu/faa-uas-bios/1011/thumbnail.jp

Unimpaired perceptual causality in children with high-functioning autism
No full textBackground:
Observers from six months are sensitive to
physical and social causality in launching
(Michotte 1946/63) and reaction (Kanizsa &
Vicario 1968), schematic events involving
movements of simple geometrical shapes.
Early in development perceptual causality
might support learning about mechanical
interactions of material bodies and about the
social interactions of intentional agents (Leslie
1988; Schlottmann & Surian, 1999).
A deficit/delay in perceptual causality fits with
theories focusing on either the social or
perceptual peculiarities characterising autism.
Ray and Schlottmann (2007) reported a link to
the latter, but not the former in lowfunctioning
young children with autism.
Objectives:
Our study investigated perceptual causality for
launch, reaction and related events in 20 highfunctioning
children with autism (mean
CA=13, VMA=9.7) and 22 typically developing
controls, to consider whether deficits in
launching that appear for younger children
with autism are overcome with higher
age/verbal ability.
Methods:
We employed a picture choice methodology
like Ray and Schlottmann (2007), but with
more articulate verbal instructions. Children
watched 14 animations (designed to test
possible explanations of any launch deficit),
choosing one of three pictures depicting
physical or social causality, or non-causality
for each.
Results:
Children with autism performed similar to
controls, with no deficit on any event.
Conclusions:
Early problems with launch perception are
overcome with age/higher verbal IQ. This
suggests a perceptual causality delay rather
than deficit in autism. Although this might still
interfere with early causal learning, that it is
overcome agrees with the general sparing of
physical reasoning in autism. Deficits on social
animations (Bowler & Thommen, 2000; Klin
2000) may only appear for complex stimuli
requiring mental state rather than goal
attributions. Thus, unimpaired perception of
reaction in autism coexists with deficits in
complex social attributions, suggesting a
discontinuity between the two
The student's guide to completing an author study
No full textThe 'Student's guide to completing an author study' emerged during the early development of the school library resource center program at Glen Stewart Elementary School in Stratford Canada on Prince Edward Island. This research process centered on an author study, with direct teaching and clear assignment. The resulting model has been adapted to various grade levels and subject areas in different schools.Source type: Electronic(1)http://proquest.umi.com/pqdweb?did=49237063&Fmt=7&clientId=65345&RQT=309&VName=PQ
Elizabeth "Liz" Overton Colton Interview Records
No full textElizabeth “Liz” Overton Colton of Asheville, North Carolina was interviewed by Lizzy Ray, a Sewanee student, on November 25th, 2023 on Zoom. While their conversation was primarily on the Black Lives Matter Movement, other topics included discussing Colton’s background and experience in the civil rights movement. We hope that this conversation will assist scholars with a further understanding of race in the United States during the early twenty-first century. Please click on the link to see the full interview
Active X-ray optics for the next generation of X-ray space telescopes
No full textDescribed within is the design, manufacture, metrology and X-ray testing of an active X-ray
prototype intended for the next generation of X-ray telescopes. One of the challenges faced by
the X-ray telescope community is how to combine high resolution and high sensitivity into one
system, as weight limitations place constraints on the optics that can be launched. Therefore the
mandate of the active X-ray prototype is to provide high sensitivity through the ability of the optics
to be nested and to deliver high angular resolution through the active control of the optic’s form.
Piezoelectric unimorph actuators provide the active component: it is intended that they will correct
for figure errors within the optic and therefore increase the angular resolution capability.
The prototype’s design is based upon an ellipsoidal segment which provides point-to-point
focussing of an X-ray source. The prototype itself is composed of an electroformed nickel optic
where the non-reflective surface is populated with 30 piezoelectric actuators and it is the production
of the prototype that is the core of the presented research. Metrology of the actuators’ influence
functions is presented and highlight the prototype’s ability to deform its optic surface by microns.
In addition, the measured influence functions are compared against finite element models and a
distinct similarity between the functions is observed.
The prototype was tested at an X-ray beamline facility in November 2008 and the results
showed the prototype’s ability to correct the optic to achieve an improved angular resolution: from
0.786 arc-minutes to 0.686 arc-minutes in terms of full width half maximum. Finally, difficulties
in the manufacture of the prototype and X-ray testing shall be presented alongside future work in
