Estimation Problems For Pooled Data, Xichen Mou

Theses and Dissertations

In epidemiological applications, individual specimens (e.g., blood, urine, etc.) are often pooled together to detect the presence of disease or to measure the concentration level of a specific biomarker. Due to the advantage of cost efficiency, pooled data are also seen in diverse areas such as genetics, animal ecology, and environmental science. With pooled data, individual observations are masked and new statistical methods are needed to estimate characteristics such as disease prevalence, the underlying density function of a biomarker, etc. We focus on three estimation problems for pooled data. Chapters 2 and 3 propose nonparametric estimators for the density function …

The Role Of The Gut Microbiome In Tumor Development And Response To 5-Fluorouracil In The Apc^Min/+ Mouse, Kristen Michele Hogan

Theses and Dissertations

Colorectal cancer (CRC) is the third most frequent cancer and the second leading cause of cancer related deaths. While CRC is initiated by mutations in critical tumor suppressor genes, its development and progression to malignancy is aided by host derived cells that are recruited to the tumor microenvironment (TME) and by cancer-associated microbiota that constitute the gut microbiome. Components of the gut microbiota have been shown to alter immune cell infiltration into tumors and influence response to therapy, disease stage, and patient survival. In previous studies, we found that ApcMin/+ mice, a model of early colon carcinogenesis, had reduced tumor …

Leveraging For-Cause Physical Activity Events For Physical Activity Promotion: An Investigation Using Self-Determination Theory, John A. Bernhart

Theses and Dissertations

Motivating individuals to live active lifestyles remains a challenging but important public health issue. For-cause physical activity events reach large groups of people, many of whom are not regularly active. However, little research has applied established health behavior theories to explain participation in for-cause events. Therefore, the purpose of this dissertation was to investigate participation in for-cause events through the lens of Self-Determination Theory (SDT).

The first study recruited participants (n=207) registered in a for-cause PA event (i.e., 5K distance or shorter) to complete online surveys that assessed need satisfaction for autonomy, competence, and relatedness; intrinsic motivation; altruism; PA behavior; …

Role Of Heart Rate Variability Biofeedback In Cognitive Performance, Chronic Pain, And Related Symptoms, James P. Winstead

Theses and Dissertations

Over-modulation of the sympathetic nervous system and reduced heart rate variability (HRV) are commonly overlooked components of pain, poor cognition (decreased attention, recall, and cognitive processing), depression, stress, and fatigue. HRV Biofeedback (HRVB) training induces HRV coherence to balance the autonomic system. Paced breathing (~6 breaths/minute) increases HRV coherence. This randomized, controlled intervention trial tested the hypothesis that HRVB would improve HRV coherence, pain (severity, interference, and catastrophizing), cognitive performance, and reduce depressive, stress, and fatigue symptoms and pain medication use in veterans. Participants were randomized to previously established HRVB or control protocols. Each participant completed a Baseline Assessment, 6 …
