Investigations Of Storage Root Development In Cassava (Manihot Esculenta Crantz), Yeetoh Chaweewan

Dissertations

The tropical root crop cassava is cultivated for its large starchy storage roots. Understanding critical processes in root tuberization is essential if improvement programs are to secure future yields for farmers. Studies were undertaken to identify critical components of storage root development at the anatomical and gene expression levels. Two types of roots were identified from greenhouse-grown stem cuttings: basal roots, which develop from the stem cut end and are prolific in nature, and nodal roots, which originate from the region of the buried axillary bud. Only nodal roots develop to produce storage organs. Anatomical sectioning was performed to determine …

Effects Of Human Disturbance On Physiology, Behavior, And Ornamentation In The Eastern Bluebird, Lauren Marjorie Gillespie

Dissertations

Overall, few studies have focused on anthropogenic disturbance on wildlife physiology. Research has typically focused on how environmentally contaminated areas or anthropogenic disturbance (e.g. noise, human activity) influences biodiversity, community structure and behavior of individual animals. However, understanding how disturbance influences some aspects of physiology can require sacrifice of the animal, prohibiting ecologically relevant measures of behavior and reproductive success. This research strives to examine covariation between testosterone (T) and corticosterone (CORT), plumage ornamentation, and behavior in two populations of eastern bluebirds (Sialia sialis) that differ in degree to which their habitat is modified by human activity.

Barefoot Vs. Shod: Effects Of Trunk Loading And Body Mass Index On Walking Mechanics, Kevin D. Dames

Dissertations

In this dissertation, the impacts of increased mass and footwear on walking mechanics and energetics were investigated. In the first study, non-obese individuals were asked to walk on a treadmill with added load to the trunk (~15% of body mass) and with and without shoes. Metabolic costs of walking increased ~12% with added load, but walking barefoot did not significantly change metabolic costs. Trunk loading increased knee and hip range of motion but failed to alter spatiotemporal measures. In study 2, non-obese individuals were asked to complete the same tasks, but this time they walked overground instead of on a …

Academic Stress And Working Memory In Elementary School Students, Maile Maria Blashill

Dissertations

Although it is sometimes believed that children do not suffer from stress and its negative consequences as adults do, children are equally affected by the harmful potential of excess stress. Because childhood is a period of rapid neurological growth, the effects of unnecessary stress may be more pronounced and enduring throughout the individual’s life. Past investigations suggest that individuals who experience excessive levels of psychological stress associated with anxiety show reduced executive functioning, especially within the area of working memory ability. Further, poor working memory has been shown to affect educational achievement across many different academic subjects. The purpose of …

Piloting A Screening Tool For Eating And Eating-Related Behavior, Michael N. Reynolds

Dissertations

Obesity is a common medical condition associated with negative health and social outcomes. Obesity has a primary malleable behavioral cause, eating more calories than are metabolized. While metabolic rate is malleable with exercise, eating can more quickly add calories than exercising can subtract them. In the past, behavioral weight-loss treatment studies relied on multi-component package interventions that have shown reliable patterns of participant weight-loss during treatment and weight-regain in follow-up. Those findings could be conceptualized as an ABA withdrawal design, eating behavior returns to baseline after the prosthetic contingencies of the treatment study are withdrawn. We must develop ways to …

N-Terminal Domains Of Copper Atpases In Plasmodium Falciparum, Dictyostelium Dicsoideum, Human Atp7b And A Chimera Of Atox1 With Metal Binding Domain Four Of Atp7b, Javan Kilango Kisaka

Dissertations

Copper transporting ATPases (Cu-ATPases) are essential for mediating copper uptake, maintaining cellular copper levels and prevention of accumulation of toxic copper. The most studied copper ATPases are the Menkes and Wilson proteins in eukaryotes, CopA and CopB found in bacteria. The precise interaction of the metal binding domains with their copper donor, the association of each metal binding domain within the N-terminal portion of the protein, how they communicate with each other, and the eventual metal ion translocation across the membrane, is little known. The variation in number of the cytosolic metal binding domains may also offer clues on the …

Missouri's Missing Education Policy: Support Systems For Districts With High Student Mobility Rates, Mary Lee Hardy

Dissertations

Missing in Missouri is state policy defining student mobility or how to measure it consistently across all districts. High mobility disproportionately impacts schools with a high poverty rate which creates a need for policy centered on this topic. Evidence indicates that children who change to a new school after the start of the regular school term negatively impacts not only that child, but the school district, teachers and staff, as well as the current students. Typically, these children arrive two to three years behind grade level academically and have social concerns. In order to best serve these students, districts need …

Changes In Health And Behavior During The Business Cycle, Mohammad Sediq Sameem

Dissertations

This dissertation considers to what extent changes in the unemployment rate – a proxy for the business cycle – drives changes in mortality and crime. I use a panel of U.S. counties from 1990 to 2013. I allow changes in the unemployment rate to have different effects upon mortality / crime in large versus small counties as well as between increases versus decreases in the unemployment rate. My results show great nuance along both these dimensions, suggesting that the effects of the business cycle are more subtle than what previous studies report. These results also give one greater insight into …
