Bobcat Abundance And Habitat Selection On The Utah Test And Training Range, Kyle David Muncey

Theses and Dissertations

Remote cameras have become a popular tool for monitoring wildlife. We used remote cameras to estimate bobcat (Lynx rufus) population abundance on the Utah Test and Training Range during two sample periods between 2015 and 2017. We used two statistical methods, closed capture mark-recapture (CMR) and mark-resight Poisson log-normal (PNE), to estimate bobcat abundance within the study area. We used the maximum mean distance moved method (MMDM) to calculate the effective sample area for estimating density. Additionally, we captured bobcats and estimated home range using minimum convex polygon (MCP) and kernel density estimation (KDE) methods. Bobcat abundance on the UTTR …

Disability Inclusion In 4-H: Aligned With The Mission, Stopped Short By Methods, Jennifer Taylor-Winney, Leanne Giordono, Marilyn Lesmeister, Meghann Fenn

Journal of Youth Development

Quality out-of-school programs can significantly improve youth development outcomes. Youth with disabilities and special health care needs, who represent 19% of all youth, are less likely than their typically developing peers to participate in out-of-school activities. This qualitative study explored factors that influence the inclusion of youth with disabilities in one state’s 4-H program. Factors that facilitated inclusion were personal attitudes and subjective norms, but lack of knowledge and limited resources led to reactive problem solving rather than proactive, organizational planning. By identifying both the factors that facilitate inclusion and those that prevent it or are perceived as barriers, youth …

Agventure: Establishing The Link Between Stem And Agriculture, Becky Ridgeway, Virginia Brown

Lighting A Path To Biofouling Prevention: Investigating The Effect Of Ultraviolet Light On Biofouling, Cierra Rose Braga

Theses and Dissertations

Ultraviolet light (UV) is considered an environmentally friendly antifouling method because it disrupts biological growth without the release of harmful toxins. The application of UV for the marine shipping industry is a relatively new concept, and there still remains many unknowns before it can be fully implemented. This research investigated several aspects of applying UVC for the control of fouling. A novel method of using embedded UV LEDs within a silicone coating for fouling control proved to be very effective at preventing fouling. The research also investigated the effect of using an external UVC light treatment to control fouling on …

Transfer Of Variable Grammars In Third Language Acquisition, Ramsés Ortín, Carmen Fernandez-Florez

Writing and Language Studies Faculty Publications

Research on linguistic variation suggests that usage patterns are deeply embedded in native and non-native speakers’ knowledge of grammar. This study explores the transfer of these variable sociolinguistic patterns at the initial stages of third language acquisition. We elicited narratives in Portuguese from two mirror-image groups of sequential Spanish-English bilingual early learners of Portuguese. Their production of variable subject pronoun expression was analysed. When comparing the two groups with regards to the linguistic factors that constrain subject pronoun expression, evidence of transfer from Spanish and not from English is consistent for both groups. We conclude that variable linguistic information is …

The Role Of Bip Co-Chaperone Sil1 In Marinesco-Sjögren Syndrome Pathogenesis, Viraj Paresh Ichhaporia

Theses and Dissertations (ETD)

Marinesco-Sjögren syndrome (MSS) is a rare, autosomal recessive, multisystem disorder, which is characterized by cerebellar ataxia, early-onset bilateral cataracts, and progressive myopathy amongst other symptoms. MSS has been attributed to mutations in the SIL1 gene, which encodes a nucleotide exchange factor for the endoplasmicreticulum- resident Hsp70 chaperone, BiP. To date, there are 46 MSS-associated mutations that have been reported in SIL1, which occur throughout this gene and are predicted to result in a loss of SIL1’s function. The large majority of these mutations cause deletions of large fractions of the SIL1 protein. Nine MSS-associated mutations are particularly interesting because they …

Signaling Induced By Inflammatory Mediators In The Rodent Pulmonary Microvasculature, Rachel Escue Helms

Theses and Dissertations (ETD)

Acute lung inflammation (ALI), stemming from a disproportionate and detrimental immune response, may arise from or complicate other disease states, leading to the often-fatal acute respiratory distress syndrome (ARDS). Because of the many culpable factors and differing points of induction, pinning down the signaling mechanisms involved in the morbidity of this disorder as well as defining an effective treatment has proved problematic. However, the most detrimental characteristic of this condition is seen regardless of the development of the response: increased microvascular permeability. Because of the architecture and the size of the pulmonary microvascular network, the lungs have a resident, sequestered …

Targeting The Colchicine Binding Site On Tubulin To Overcome Multidrug Resistance And Anticancer Efficacy Of Selective Survivin Inhibitors, Kinsle E. Arnst

Theses and Dissertations (ETD)

Tubulin inhibitors are widely used as chemotherapeutic agents, and their successis attributed to their ability to target microtubule dynamics and disrupt critical cellular functions including cell signaling, motility, intracellular trafficking, and mitosis. Interference with microtubule dynamics consequently disrupts mitotic progression and ultimately leads to apoptosis, validating microtubule dynamics as an excellent target for anticancer agents. While this class of drug has proven to be effective against many cancer types, the clinical efficacy of current tubulin inhibitors is often limited by the development of multidrug resistance. The most common form of resistance to these agents arises from the overexpression of drug …

Molecular Response Of Retinal Pigment Epithelial Cells To Oxidized Lipoproteins: Global And Targeted Studies, Diwa Koirala

Theses and Dissertations (ETD)

Global-scale examinations of biological systems at the molecular level complement targeted approaches to scientific inquiry that focus on specific subsets of biomolecules, or on a single molecule of interest. In this dissertation, we utilized both the discovery-based approach to evaluate the proteomics workflows centered around mass spectrometry as the key technology, and the targeted approach to examine the molecular response of RPE due to oxidized lipoproteins (oxLDL) treatments. A crucial aspect in proteomics studies is the design of bioanalytical strategies that maximize coverage of the complex repertoire of a proteome. A comprehensive, unbiased examination of the proteome represents a powerful …

Genetic Exploration Of Hereditary Immune Diseases, Cheng Tian

Theses and Dissertations (ETD)

An autoimmune disease is a condition arising from an abnormal immune response to a normal body part. There are at least 80 types of autoimmune diseases, rheumatoid arthritis and systemic sclerosis are two of them. My study focuses on these two diseases. Our hypothesis is that mutated genes lead to autoimmune diseases that cause the immune system to attack the human body. The mutated genes cause the gene expression levels to change which fail to properly regulate the body's functions, resulting in immune system diseases. I used existing mouse models to improve the understanding of these two diseases.

The first …

Roles Of Cytosolic Nucleic Acid Sensors In Cancer And Infection, Qifan Zhu

Theses and Dissertations (ETD)

Pattern recognition receptors are innate immune sensors that recognize pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs) with crucial roles in host defense against microbial infection, autoimmune diseases and cancer. Cytosolic nucleic acids including DNA and RNA originate from pathogens or self-cells, which form major groups of PAMPs and DAMPs. A range of nucleic acid sensors have evolved to sense various types of nucleic acids. How different DNA-sensing pathways regulate microbial infection and cancer is the focus of this dissertation.

Stimulator of IFN genes (STING) is a cytosolic innate immune sensor for cyclic dinucleotides that also serves a dual …

Analyzing Policies Through A Dohad Lens: What Can We Learn?, Julia M. Goodman, Janne Boone-Heinonen, Dawn M. Richardson, Sarah B. Andrea, Lynne C. Messer

OHSU-PSU School of Public Health Faculty Publications and Presentations

Social, health, and environmental policies are critical tools for providing the conditions needed for healthy populations. However, current policy analyses fall short of capturing their full potential impacts across the life course and from generation to generation. We argue that the field of Developmental Origins of Health and Disease (DOHaD), a conceptual and research framework positing that early life experiences significantly affect health trajectories across the lifespan and into future generations, provides an important lens through which to analyze social policies. To illustrate this point, we synthesized evidence related to policies from three domains—family leave, nutrition, and housing—to examine the …

Evaluation Of Alternative Valorization Options For Institutional And Industrial Food Wastes, Swati Hegde

Theses

In recent years many countries and several regions in the United States have passed legislation on banning landfilling of organic waste. It is a well-known fact that organic wastes, including food scraps, generate methane under anaerobic landfill environments and contribute significantly to global warming. As more regions are mandated to follow the landfill ban, there is an increasing demand for alternative technologies for the disposal, treatment and upcycling of food wastes. Disposal and treatment may not result in any value-added products and hence are not the most efficient ways to manage food waste. As food waste has a high energy …
