Improving the prediction of differential item functioning: a comparison of the use of an effect size for logistic regression DIF and Mantel-Haenszel DIF methods
(Texas A&M University, 2007-09-17)
Psychometricians and test developers use DIF analysis to determine if there is possible bias in a given test item. This study examines the conditions under which two predominant methods for determining differential item ...
Damage initiation, progression and failure of polymer matrix composites due to manufacturing induced defects
(Texas A&M University, 2007-09-17)
In polymer matrix composites (PMCs) manufacturing processes can induce de-
fects, e.g., voids, fiber misalignment, irregular fiber distribution in the cross-section
and broken fibers. The effects of such defects can be ...
Genetic analysis of canine hip dysplasia
(Texas A&M University, 2007-04-25)
The morphologic variability seen in the domestic dog, Canis lupus familiaris, is
unique among mammals. Selective pressures imposed by humans have divided dogs into
almost 400 separate breeds. Selection has also led to the ...
Metal interactions and activities of truncated and extended hammerhead ribozyme constructs
(Texas A&M University, 2007-04-25)
The hammerhead ribozyme (HHRz) catalyzes a site-specific
phosphodiester bond cleavage reaction that is enhanced by the presence of
metal cations. Metal cations are thought to aid in the folding and possibly the
catalytic ...
When innovativeness in form matters: the joint impact of form innovativeness and expected innovativeness type on product evaluations over time
(Texas A&M University, 2007-09-17)
Past research in the area of product innovativeness has been dominated by studies
conducted at the firm level. Furthermore, these studies principally lack a consumer
perspective on the product innovativeness - product ...
Mentors' perceptions of the effectiveness of the components and technological venues implemented in online teacher induction programs for novice teachers
(Texas A&M University, 2007-04-25)
This descriptive study provided a synthesis of the form, structure, activity and
relationship components utilized by online teacher induction programs designed to
support novice teachers. Mentors involved in online teacher ...
Genetic diversity and performance of maize varieties from Zimbabwe, Zambia and Malawi
(Texas A&M University, 2007-04-25)
Large scale and planned introduction of maize (Zea mays) in southern Africa was
accomplished during the last 100 years. Since then, smallholder farmers and breeders
have been selecting varieties best adapted to their ...
Work-life variables influencing attrition among beginning agriscience teachers of Texas
(Texas A&M University, 2007-09-17)
The purpose of this study was to describe the perceptions of former beginning agriscience teachers and to explore the relationships between these perceptions, the characteristics of former beginning agriscience teachers, ...
Identification of the membrane association of BV/ODV E26 and the domains in BV/ODV E26 responsible for nuclear trafficking to intranuclear microvesicles
(Texas A&M University, 2007-04-25)
The baculovirus Autographa californica nucleopolyhedrovirus (AcNPV) has two
viral forms, budded virus (BV) and occlusion derived virus (ODV). The envelopment of
these two viral forms occurs at different locations: BV ...
Instrumentation for parallel magnetic resonance imaging
(Texas A&M University, 2007-04-25)
Parallel magnetic resonance (MR) imaging may be used to increase either the
throughput or the speed of the MR imaging experiment. As such, parallel imaging may
be accomplished either through a "parallelization" of the MR ...
