The purpose of this study was to investigate the effect
of an eight-week instructional program, using different
activities and apparatus, upon the balance performance
of hearing-impaired children, ages 6-12. Balance was
measured by the Bruininks-Oseretsky Test of Motor Proficiency
(Subtest 2: Balance) as a pre- and post-test to
determine if...

could improve the motor performance of their moderately and severely
mentally retarded children through the implementation of the
Data-Based Gymnasium (DBG) Instructional Model as a supplement to the
school program. The DBG Instructional Model is an individualized
system...

effects of three levels of contextual interference on the
acquisition and retention of a sequential motor skill, by
moderately mentally retarded and nonretarded subjects. The
subjects were functioning between an eight and twelve year
level. The dependent measures included; Reaction Time...
The purpose of this research was to study the
effects of cerebral palsy on the ability to plan and
execute a gross motor movement, as measured by the
fractionation of Simple Reaction Time (SRT) into its
premotor (central) and motor (peripheral) components.
The experimental task required subjects (N = 10...
The purpose of this study was to validate a field
test of cardiorespiratory fitness for men with mental
retardation. The subjects were 19 healthy men with
moderate mental retardation whose mean age was 26 years
with a mean IQ of 48. Each subject underwent a
maximal treadmill test utilizing a...
The purpose of this research was to determine the extent to
which parents and professionals were in agreement prior to and
following intervention regarding their Judgement of the gross motor
abilities of the parents' preschool children.
Each child was tested by a professional on the Ulrich Test of
Gross Motor...
Special Olympics International, an organization
committed to providing sport opportunities for children
and adults with mental retardation, has been a major
advocate in promoting competitive experiences for the
mentally retarded. Few studies have focused on the
effects of participation in competitive athletics on
individuals who are mentally retarded. The purpose...
The purpose of this study was to identify competencies
which are perceived as important by Thai adapted physical
educators, to determine the differences that exist in the
way physical education professors and adapted physical
educators judge the level of each competency, and to
recommend a set of competencies for adapted...
The purpose of this study was to investigate the effect of untrained and
trained peer tutors on the motor performance of students with developmental
disabilities in integrated physical education classes. This study utilized a single
subject delayed multiple baseline design across subjects.
Six elementary age students with developmental disabilities and...
The purpose of this study was to investigate the effect of trained hearing peer
tutors on the physical activity levels of deaf students in integrated elementary
physical education classes. This study utilized a single subject multiple
baseline design across subjects.
Eight deaf 4th and 5th grade students and eight hearing...
This study was designed to assess the relationship of selected
factors to the developmental outcome of fundamental motor
skill performance in young children ages 3 to 6 years residing
in foster or adoptive care, and have a documented history of
prenatal exposure to cocaine and other drugs. Using an
ecological...
This retrospective study investigated the incidence, characteristics, and
risk factors of bone fracture among a group of 518 adults with severe mental
retardation between 25 and 75 years old. Data were collected from a large state
developmental center in the Western United States between April 1, 1991 and
March 31,...
Technological growth in agriculture increases crop output but it could lower output price in the market. Economic impact assessment in ex-ante analysis usually does not include these indirect supply responses, which can overestimate the economic potential of new technology. This dissertation provides an integrated farm-level ex-ante impact assessment model to...
This thesis describes in-vitro and in-vivo evaluation of a transdermal atenolol formulation developed at Oregon State University, College of Pharmacy. The formulation was prepared from carbomer as a gel base with propylene glycol, glycerol, ethanol, polysorbate 80 and dimethyl-isosorbide (DMI) as mixture of penetration enhancing agents. The effect of the...
The methodology to perform bioequivalence studies for prodrug products has not been finalized by FDA leaving the investigators to speculate over the proper approach. This study innovatively utilized the bootstrap methods for testing in vivo bioequivalence on both parent drug and metabolite of four prodrug products: Clopidogrel, Prednisone, Allopurinol, and...
Development research and policy aim to improve household welfare by improving access to assets and economic opportunities (Besley & Burgess 2000; Deininger et al. 2003). In rural and agrarian contexts, these goals may be achieved by well-functioning markets for outputs, inputs, off-farm work, and credit. The status of these markets...
Increased temperature and precipitation variability and frequent extreme weather events due to climate change pose a threat to farming operations and agricultural communities. The recent IPCC assessment shows that the projected climate change will, on average, reduce wheat yields by 5% in temperate regions without adaptation and even more if...
The study was devoted to formulating answers to the following
questions:
1. What factors did students report to be influential in their
choice of a community college major ?
2. What factors influenced students in the selection of a
community college to attend?
3. What factors influenced students to continue...
Dissolution profiles of two commercial products (Motrine and Rufen®) were analyzed and compared at 8 pH levels, ranging from pH 2.0 to pH 8.0. It was demonstrated, as expected, that the rate and extent of ibuprofen dissolution dissolution was pH dependent. In vitro dissolution characteristics of the ibuprofen solid dispersion...
A two-part study was conducted with three poorly water soluble
drugs (phenylbutazone, tolbutamide, theophylline) to develop two new
drug delivery systems based on physical-chemical approaches.
In the first part, tolbutamide and phenylbutazone were made into
solid dispersions with various excipients using a lyophilization
technique. In vitro dissolution studies of these...
This thesis is concerned with the development of a unique
parallel sort-merge system suitable for implementation in VLSI.
Two new sorting subsystems, a high performance VLSI sorter and a
four-way merger, were also realized during the development
process. In addition, the analysis of several existing parallel sorting
architectures and algorithms...
An oral Vibrio vaccine for salmonids was developed.
The vaccine was produced by spray coating lyophilized
formalin-killed whole cells of Vibrio anguillarum (VA LS 1-
74) onto non-pareil sugar beads. Then methacrylic acrylic
acid copolymer (Eudragit L-30D) was applied as an enteric
protective coating.
Using x-ray radiographic techniques, it was...
The importance of physical activity is well documented (Haskell et al., 2009a; McReynolds & Rossen, 2004; Steinbeck, 2001). Despite physical activity’s benefits, many individuals are not meeting current weekly physical activity guidelines recommending ≥ 150 minutes of moderate or ≥ 75 minutes of vigorous aerobic physical activity and 2 or...
There is a known relationship between total physical activity (PA) and weight status in children; however, there is a paucity of data examining the prospective relationship between school day PA and obesity among rural elementary school children. A large number of cross-sectional studies have demonstrated that higher levels of PA...
