Sintering of

PLZT Ceramics: Journal of the
American

Society, Vol.
56, No. 9.
(1973), pp.
479-480.An
improved
atmosphere
sintering
process was
developed for
fabricating
large
transparent
PLZT plates
for
electrooptic
applications.
Cold-pressed
9/85/35 PLZT
slugs were
sintered in O2
in Pt
crucibles for
~45 min at
1180oC and
were then
heat-treated
in air for 60
h at 1200oC in
Al2O3
crucibles
containing
PbZrO3
atmosphere
powder.
Transparent
plates as
large as 8.4
cm in diameter
and I cm thick
were thus
fabricated. A
mechanism is
proposed which
qualitatively
accounts for
the success of
this process.

in the UAE:
Its Effect on
Allergy and
Respiratory
Symptoms: Journal of
Asthma, Vol.
32, No. 2.
(1995), pp.
117-124.The
aim of this
paper was to
study the
effect of pets
and other
domestic
animals on
bronchial
asthma among
United Arab
Emirates (UAE)
schoolchildren
aged 6-14
years. A
cross-sectiona
l study of 850
schoolchildren
living in both
urban and
rural areas
(average age
9.36 ± 2.11
years, 46.8%
boys and 53.2%
girls) was
conducted
using
self-administe
red
questionnaires
between
October 1992
and May 1993.
Prevalence
rate for
asthma,
rhinitis,
wheeze, cough,
and eczema in
children from
families with
and without
animals were
investigated.
A total of
40.7% of
families
studied were
found to keep
animals in
their homes.
Children from
families with
animals were
found to have
a
significantly
higher
prevalence
rate of
respiratory
symptoms than
those without.
The prevalence
rate for
asthma in
children with
animals was
found to be
twice that of
children
without (RR:
2.03; 95% CI:
1.402.95). The
risk of having
chronic cough
(RR: 1.93; 95%
CI: 1.213.10),
breathlessness
/chest
tightness (RR:
2.53; 95% CI:
1.594.02),
chronic wheeze
(RR: 2.10; 95%
CI: 1.203.67),
allergic
rhinitis (RR:
1.53; 95% CI:
1.172.00) was
significantly
higher in
children with
animals than
in children
without.
Similarly, the
risk of having
eczema (RR:
2.55; 95%, CI:
1.743.75) was
significantly
higher among
children with
animals than
among those
without.
Overall, there
was a highly
statistically
significant
difference in
the prevalence
of asthma,
wheeze,
nocturnal
cough, eczema,
and rhinitis
between
children in
families with
animals and
those without
(p < 0.0001).
It is
concluded that
unlike what is
alleged to be
known, a large
proportion of
the national
population
(40.7%) kept
animals at
home, and that
was an
important
aggravating
factor, which
should be
considered in
the management
of asthma in
the UAE.

aesthetics and
utility:
designing
ambient
information
visualizations: Information
Visualization,
2003. INFOVIS
2003. IEEE
Symposium on
(2003), pp.
233-240.Unlike
traditional
information
visualization,
ambient
information
visualizations
reside in the
environment of
the user
rather than on
the screen of
a desktop
computer.
Currently,
most dynamic
information
that is
displayed in
public places
consists of
text and
numbers. We
argue that
information
visualization
can be
employed to
make such
dynamic data
more useful
and appealing.
However,
visualizations
intended for
non-desktop
spaces will
have to both
provide
valuable
information
and present an
attractive
addition to
the
environment -
they must
strike a
balance
between
aesthetical
appeal and
usefulness. To
explore this,
we designed a
real-time
visualization
of bus
departure
times and
deployed it in
a public
space, with
about 300
potential
users. To make
the
presentation
more visually
appealing, we
took
inspiration
from a modern
abstract
artist. The
visualization
was designed
in two passes.
First, we did
a preliminary
version that
was presented
to and
discussed with
prospective
users. Based
on their
input, we did
a final
design. We
discuss the
lessons
learned in
designing this
and previous
ambient
information
visualizations
, including
how visual art
can be used as
a design
constraint,
and how the
choice of
information
and the
placement of
the display
affect the
visualization.

without
attention:
results of a
new method.: Cognit
Psychol, Vol.
24, No. 4.
(October
1992), pp.
502-534.Having
found by the
use of a new
method for
examining
perception
without
attention that
grouping and
texture
segregation do
not seem to
occur (see
Mack, Tang,
Tuma, Kahn, &
Rock (1992)
Cognitive
Psychology,
24, we go on
to ask what is
perceived
without
attention
using this new
method. Our
subjects
receive only
one
inattention
trial in a
sequence of
trials
involving a
visual
distraction
task. In
addition to
the
distraction
task in the
inattention
trial,
subjects
received a
stimulus of
which they had
no prior
knowledge or
expectation
and were
questioned or
tested
directly
afterward for
their
perception of
that stimulus.
Two subsequent
trials
containing
test stimuli
serve as
within-subject
controls. The
results of a
series of
experiments
indicate that
the presence
of one or more
stimulus
objects and
their
locations are
preattentively
perceived, as
is their
color, but
shape is not.
Because
individual
items are
detected
without
attention, we
conclude that
perceptual
organization
is initially
based on a
principle in
which
connected
regions of
uniform
stimulation
are inferred
to be discrete
units (the
principle of
uniform
connectedness)
. One
striking,
unexpected
finding is
that without
attention many
subjects have
no awareness
at all of the
stimulus
object, an
effect we call
inattentional
blindness.

perspectives
from cognitive

Vol. 79, No.
1-2. (April

115-134.Four
basic
approaches
that have been
used to
demonstrate
perception
without
awareness are
described.
Each approach
reflects one
of two types
of
experimental
logic and one
of two
possible
methods for
controlling
awareness. The
experimental
logic has been
either to
demonstrate a
dissociation
between a
measure of
perception
with awareness
and a measure
that is
sensitive to
perception
without
awareness or
to demonstrate
a qualitative
difference
between the
consequences
of perception
with and
without
awareness.
Awareness has
been
controlled
either by
manipulating
the stimulus
conditions or
by instructing
observers on
how to
distribute
their
attention. The
experimental
findings based
on all four
approaches
lead to the
same
conclusion;
namely,
stimuli are
perceived even
when observers
are unaware of
the stimuli.
This
conclusion is
supported by
results of
studies in
which
awareness has
been assessed
with either
objective
measures of
forced-choice
discrimination
s or measures
based on
verbalizations
of subjective
conscious
experiences.
Given this
solid
empirical
support for
the concept of
perception
without
awareness, a
direction for
future
research
studies is to
assess the
functions of
information
perceived
without
awareness in
determining
what is
perceived with
awareness. The
available
evidence
suggests that
information
perceived
without
awareness both
biases what
stimuli are
perceived with
awareness and
influences how
stimuli
perceived with
awareness are
consciously
experienced.
