Inbreeding depression is the reduction in fitness and vigor resulting from mating of close relatives observed in many plant and animal species. The extent to which the genetic load of mutations contributing to inbreeding depression is due to large-effect mutations versus variants with very small individual effects is unknown and may be affected by population history. We compared the effects of outcrossing and self-fertilization on 18 traits in a landrace population of maize, which underwent a population bottleneck during domestication, and a neighboring population of its wild relative teosinte. Inbreeding depression was greater in maize than teosinte for 15 of …

Emerging Themes In The Molecular Pathogenesis Of Enterotoxigenic Escherichia Coli, James M Fleckenstein, Alaullah Sheikh

2020-Current year OA Pubs

Enterotoxigenic Escherichia coli (ETEC) are ubiquitous diarrheal pathogens that thrive in areas lacking basic human needs of clean water and sanitation. These genetically plastic organisms cause tremendous morbidity among disadvantaged young children, in the form of both acute diarrheal illness and sequelae of malnutrition and growth impairment. The recent discovery of additional plasmid-encoded virulence factors and elucidation of their critical role in the molecular pathogenesis of ETEC may inform new approaches to the development of broadly protective vaccines. Although the pathogens have been closely linked epidemiologically with nondiarrheal sequelae, these conditions remain very poorly understood. Similarly, while canonical effects of …

Examining The Effects Of Power Posing On Stress Reactivity And Performance, Mitzi D. Ochoa

Master's Theses

Power posing is a concept that has garnered widespread attention due to claims thatan expansive powerful posture can improve self-perceptions of power, trigger changes in hormone levels, and improve behavioral outcomes including enhanced performance in social evaluative situations. Recently, these claims have been challenged by studies that failed to replicate the power boosting effects of expansive poses. This study aimed to address inconsistencies in the power posing literature and replicate original findings while controlling for potential effects of experimenter bias and touch. It was predicted that a high-power pose would reduce cortisol, increase perceptions of power, and improve performance. To …

The Filipino American Diet: Generational Comparison Of Acculturation, Health Literacy, And Dietary Patterns, Regina Reina

Master's Theses

There is evidence to suggest that Filipino Americans (FAs) are at greater risk for cardiovascular disease (CVD) and chronic conditions when compared to other Asian American subgroups. However, research on possible risk factors for this group is limited as race classifications are seldomly disaggregated. Having limited health literacy is known to be a contributing factor in health disparities among immigrant populations, though it has largely been understudied among FAs. The comparison of dietary intake, acculturation, dietary acculturation, and health literacy between Philippine-born (PBs) FAs and U.S-born (UBs) FAs has not previously been described.

Rapid Enhancement Of Subcortical Neural Responses To Sine-Wave Speech, Fan-Yin Cheng, Can Xu, Lisa Gold, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

The efferent auditory nervous system may be a potent force in shaping how the brain responds to behaviorally significant sounds. Previous human experiments using the frequency following response (FFR) have shown efferent-induced modulation of subcortical auditory function online and over short- and long-term time scales; however, a contemporary understanding of FFR generation presents new questions about whether previous effects were constrained solely to the auditory subcortex. The present experiment used sine-wave speech (SWS), an acoustically-sparse stimulus in which dynamic pure tones represent speech formant contours, to evoke FFR_SWS. Due to the higher stimulus frequencies used in SWS, this …
