Cervical cancer is the fourth most common cancer in women worldwide. Recently it has been shown that microbiota play a role in some types of cancer. Therefore, to understand whether microbes contribute in any way to the development and progress of cervical cancer, we investigated the cervical microbiome via analysis...
Cervical cancer is the fourth most common cancer in women worldwide with human papillomavirus (HPV) being the main cause the disease. Chromosomal amplifications have been identified as a source of upregulation for cervical cancer driver genes but cannot fully explain increased expression of immune genes in invasive carcinoma. Insight into...
Jordan has a higher fertility rate (3.8) than the averages of countries similar in income to Jordan (2.2) and compared to the Middle East and North Africa region as a whole (2.8) (WHO, WB, UNICEF, & DHS, 2011). The findings of the 2009 Jordanian Population and Family Health Survey demonstrated...

Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...
Improper disposal of unused human and pet pharmaceuticals and personal care products (PPCPs) are an emerging public and watershed health threat around the world. Although some waste stream reduction programs such as PPCPs "take-back" exist, there is limited research in current programs on reducing the entry of PPCPs into the...

Complex information environments are often organized as hierarchies. However, computational models of Information Foraging Theory (IFT) have almost entirely ignored this fact. Models and tools for predicting programmer navigations have ignored people’s foraging behavior across hierarchies —called hierarchical foraging. Without modeling hierarchical foraging, our ability to build tools to support...

The aim of this study is to identify material preferences in the building environment in cities and to determine if the building cultural background...
Uncontrolled direct fire rockets exhibit high impact point dispersion, even at relatively short range, and as such have been employed as area weapons on the battlefield. In order to reduce the dispersion of a direct fire rocket, feedback control is employed to fire short-duration solid rocket pulses mounted near the...
"What’s wrong with this AI?" Explainable AI (XAI) researchers are moving beyond explaining an AI’s actions, to helping users detect an AI’s failures. However this detection may not be enough—for actionability, we often need to pinpoint which part failed. We investigate how AAR/AI, a structured assessment process, supports users with...

Lampreys (Petromyzontiformes) have persisted over millennia and now suffer a recent decline in abundance. Complex life histories may have factored in their persistence; anthropogenic perturbations in their demise. The complexity of life histories of lampreys is not understood, particularly for the anadromous Pacific lamprey, Entosphenus tridentatus Gairdner, 1836. Our goals...
Addressing the ongoing decline of Pacific Lamprey Entosphenus tridentatus across its range along the west coast
of North America requires an understanding of all life history phases. Currently, spawning surveys (redd counts)
are a common tool used to monitor returning adult salmonids, but the methods are in their infancy for...
The importance of hormone reservoirs in mature teleost eggs is
unknown. To elucidate the effects of hormones on embryonic development,
