Obesity: a growing concern about fetal nutrition
(University of Missouri--Columbia, 2006)
Obesity is a growing epidemic and a major health concern in the United States and elsewhere. The Fetal Basis of Adult Disease (FBAD) theory holds that events that occur during development can permanently alter gene expression ...
Perfectionism, self-discrepancy, and disordered eating in black and white women
(University of Missouri--Columbia, 2006)
The current study investigates the relation between perfectionism and self-discrepancy, and whether their confluence predicts later disordered eating in a sample of Black and White college women. The combination of high ...
Modeling of molecular and particulate transport in dry spent nuclear fuel canisters
(University of Missouri--Columbia, 2007)
There are two important phenomena associated with the depressurization of a dry spent nuclear fuel canister after the formation of a through-wall pinhole breach. The first phenomenon is the release from the canister of any ...
Mathematics textbooks and state curriculum standards : an analysis of the alignment between the written and intended curricula
(University of Missouri--Columbia, 2007)
This study documented the alignment between state curriculum standards and the treatment of fraction concepts and computation in popular elementary and middle grades mathematics textbooks. Grade-level Learning Expectations ...
Phosphinimines as potential technetium environmental sensors
(University of Missouri--Columbia, 2007)
Phosphinimines, R₃P=NSiMe₃, undergo hydrolysis to form the phosphiniminiumcation, R₃P=NH₂+, which forms the ion pair [R₃P=NH₂+][X-] in the presence of an anion.Preliminary studies show that in the presence of TcO₄-, ...
The 2004 presidential election between George W. Bush and John F. Kerry : an analysis of visually comparative televised advertisements
(University of Missouri--Columbia, 2007)
This study used impression management theory and framing to explore how George W. Bush and John F. Kerry used nonverbal behavior cues (body movement, eye gaze, facial expression, posture, gestures, and dress/clothing) and ...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
I used both demographic modeling and experimental field research to evaluate the role of terrestrial habitat in the population dynamics and conservation of pond-breeding amphibians. I began by using literature data to ...
Young children at-risk for externalizing behavior problems : examination of behavior change utilizing universal positive behavior support strategies
(University of Missouri--Columbia, 2007)
A single-subject multiple baseline research design was used to examine effects of teacher use of universal Positive Behavior Support strategies on the externalizing behavior of four Head Start students who were identified ...
A determination of the reliability and construct validity of the Leadership Capacity School Survey
(University of Missouri--Columbia, 2007)
The purpose of this quantitative case study was to determine the psychometric properties of the Leadership Capacity School Survey (Lambert, 2003). The Leadership Capacity School Survey (LCSS, Lambert) was electronically ...
A study of parametric excitation applied to a MEMS tuning fork gyroscope
(University of Missouri--Columbia, 2007)
The current MEMS ( gyroscopes which normally use the electro static force to excite the comb drive are faced with the limitations such as low precision, coupling problem, and poor robustness. We propose to use parametric ...
Quantitative biological studies at cellular and sub-cellular level
(University of Missouri--Columbia, 2007)
We developed a translational magnetic tweezers for quantitative measurements at cellular and sub-cellular level. In the cellular studies, multiple membrane tethers were extracted simultaneously under constant force transduced ...
Dedications in clay : terracotta figurines in early Iron Age Greece (c. 1100-700 BCE)
(University of Missouri--Columbia, 2007)
This dissertation explores early Greek religion and society through a contextual analysis of the ritual use of terracotta votive figurines in the Early Iron Age, c. 1100-700 BCE. I have compiled the major deposits of ...
Structural and functional studies of proline catabolic enzymes
(University of Missouri--Columbia, 2007)
Catabolism is the oxidation of organic nutrients into simple end molecules to extract energy. For proline, the catabolic pathway involves two enzymes, Lproline dehydrogenase (PRODH, EC 1.5.99.8) and L-[delta]¹-pyrroline- ...
