The Effect Of Test Difficulty On Perceived Memory Performance, Phoebe S. Bean

Graduate Student Theses, Dissertations, & Professional Papers

Neuropsychological testing is a critical element of the assessment and treatment of a host of neurological disorders, such as Alzheimer’s Disease, stroke, and traumatic brain injury. Certain non-neurological variables may also affect an individual’s test performance. Such secondary factors may include current psychiatric issues, chronic pain, sleep, and the effort put forth during testing. Little is known, however, about the effect the testing process itself has on people’s actual and perceived cognitive abilities. For example, the process of undergoing memory testing may, through a variety of mechanisms, influence memory performance and impact the person such that their view of their …

Characterization Of Nucleocapsid-Rna Interactions In Rift Valley Fever Virus Infection, Miyuki Hayashi

Graduate Student Theses, Dissertations, & Professional Papers

Rift Valley fever virus (RVFV) is a mosquito-borne virus that infects humans and livestock and exhibits potential for global spread. No vaccine or treatment is currently available for human use. The nucleocapsid protein (N) in RVFV is a multifunctional RNA-binding protein that is necessary for viral replication and dissemination. Because of its essential roles, N is a promising candidate to be targeted for anti-RVFV therapy. The goal of this dissertation is to characterize N-RNA interactions in RVFV infected cells. To achieve this goal, two methods, strand-specific reverse transcription and quantitative PCR (RT-qPCR) as well as multiple reaction monitoring mass spectrometry …

Generation, Characterization, And C-H Bond Activation Reactivity By Mononuclear High-Valent Cobalt(Iv) And Nickel(Iv) Non-Oxo Complexes, Yubin Maria Kwon

Graduate Student Theses, Dissertations, & Professional Papers

The study of terminal high-valent transition metal-oxo complexes has increased significantly over the years as it is believed that they are key reactive intermediates for a wide range of biological and industrial catalytic processes. These complexes are powerful oxidants for the activation of strong C-H bonds. The chemical and physical properties of these complexes remain elusive. It is therefore desirable to study the properties and function of these complexes through synthetic models. There have been many efforts and reports of synthetic high-valent metal-oxo complexes of early and middle transition metals (up to group 8 on the Periodic Table of Elements), …

Management And Conservation Of Westslope Cutthroat Trout In An Impacted, Connected River System, Troy Weant Smith

Graduate Student Theses, Dissertations, & Professional Papers

Westslope cutthroat trout Oncorhynchus clarkii lewisi (WCT) is a native species of high conservation value that historically exhibited partially migratory behavior throughout its range. Long-term persistence of WCT is threatened by human habitat modification, fragmentation, introduction of non-native species, and hybridization. As a result of these changes, remnant populations in Montana have shifted toward resident populations in headwater systems and away from migratory populations in larger connected river networks. This is compounded by the historic introduction of rainbow trout O. mykiss (RBT) that hybridize with WCT, especially in larger river habitats. Rock Creek in western Montana, USA was historically managed …

Policy And Collaborative Governance: Case Studies Of Three Wildlife Crossings, Nicholas Maya

Graduate Student Theses, Dissertations, & Professional Papers

Over the last several decades, the number of wildlife-vehicle collisions in North America has significantly increased, driving substantial loss of human life and wildlife and economic costs. The most effective wildlife-vehicle collision mitigation is wildlife crossing structures (undercrossings and overcrossings), with some studies suggesting they can reduce wildlife-vehicle collisions by 97% when paired with wildlife exclusion fencing. However, cost, funding, jurisdiction, land ownership, and local support are limiting factors in constructing these crossing structures. This paper presents case studies of three crossing projects in Snoqualmie, Washington, Teton County, Wyoming, and Summit County, Colorado, to illustrate the similarities and differences in …

Wildlife-Friendly Fence Policy On Federal Public Lands Managed By The U.S. Forest Service And Bureau Of Land Management, Joshua D. Elliott

Graduate Student Theses, Dissertations, & Professional Papers

Many wildlife species are negatively impacted by the presence of fences on the landscape. Climate change is only exacerbating the problem as home ranges shift and species face heightened levels of stress. In recent decades, wildlife biologists have studied these impacts and devised ways of constructing fences to increase habitat connectivity and significantly reduce fence-related injury and mortality rates. Conservationists attempting to address this issue on a landscape level face significant challenges resulting from complex land ownership patterns, specifically across the western United States.

The two largest landowners in the U.S. are the Bureau of Land Management (BLM) and the …

Sustainability In A Changing Landscape: Identifying The Effects Of Land Use On Vegetation And Mammal Communities, Christopher Paul Hansen

Graduate Student Theses, Dissertations, & Professional Papers

Increases in habitat loss and fragmentation from anthropogenic disturbance present substantial threats to global biodiversity; thus, sustainable land management will be crucial to support current and future generations of humans and wildlife. In the western United States, approximately 70% of the land is grazed by domestic cows (i.e., “cattle”), and urban development is increasing rapidly. These land uses may affect vegetation composition and mammal communities, which could alter ecosystem function through bottom-up or top-down processes. Therefore, understanding the responses of vegetation and mammal communities to these practices is important when considering socio-ecological sustainability.

In this dissertation, I evaluated how cattle …

Using Formulation To Unlock Vaccine Adjuvant Efficacy For Toll-Like And C-Type Lectin Receptor Agonsts, Kristopher Kenneth Short

Graduate Student Theses, Dissertations, & Professional Papers

Ligands for pattern recognition receptors (PRRs) have been isolated or synthesized for use as adjuvants in order to improve the magnitude and quality of the immune response of vaccines. In particular, basic research of toll-like receptor (TLR) and C-type lectin receptor (CLR) families has culminated in the production of novel ligands with agonist activity. To use these PRR agonists as vaccine adjuvants, it is necessary to properly formulate them in delivery systems to unlock their agonist activity. The objective of this work was to develop liposomal and oil-in-water (O/W) emulsion formulations for TLR4 and TLR7/8 agonists and to develop O/W …

Monitoring The Wetland Landscape: White-Faced Ibis (Plegadis Chihi) Breeding Habitat As A Model Assemblage, Shea P. Coons

Graduate Student Theses, Dissertations, & Professional Papers

Wetlands structure landscape biodiversity by providing critical habitat to numerous fish and wildlife species. However, climate change, growing human populations, and shifting land use practices strain limited water supplies that sustain wetlands in the semi-arid western US. Conserving a wetland network with prominent value to wildlife is paramount to ensure future security of habitat and ecosystem processes. Here, I use white-faced ibis (Plegadis chihi; hereafter ‘ibis’) breeding colonies as a model system to identify and monitor a landscape-scale wetland network across the semi-arid western US. Ibis serve an important role in marking ecologically important wetland networks because they require a …

Ensemble Protein Inference Evaluation, Kyle Lee Lucke

Graduate Student Theses, Dissertations, & Professional Papers

The Protein inference problem is becoming an increasingly important tool that aids in the characterization of complex proteomes and analysis of complex protein samples. In bottom-up shotgun proteomics experiments the metrics for evaluation (like AUC and calibration error) are based on an often imperfect target-decoy database. These metrics make the inherent assumption that all of the proteins in the target set are present in the sample being analyzed. In general, this is not the case, they are typically a mix of present and absent proteins. To objectively evaluate inference methods, protein standard datasets are used. These datasets are special in …

Effects Of Prescribed Fire On Drought Resistance And Recovery In Mixed Conifer Forests Of Lassen Volcanic National Park, California, Zachary J. Wenderott

Cal Poly Humboldt theses and projects

Forests throughout much of the western United States are experiencing increasing climatic variability, often resulting in decreased forest productivity and elevated likelihood of tree mortality. Severe drought, such California’s recent 2012-2015 drought, are projected to increase in intensity, frequency, and severity throughout much of this region in coming years. Forest management has long relied on prescribed fire and mechanical thinning to reduce fuel loads and ameliorate potential fire hazards. These treatments may also have the ability to reduce stand density, alleviate competitive pressures, and allow residual trees access to critical resources during periods of extreme stress. Utilizing a long-term National …

Cal Poly Humboldt theses and projects

This study surveyed the diverse families at the HSU Children’s Center who have children ranging in age from infancy to preschool. Since the COVID-19 pandemic, the way the Children’s Center operates has changed in profound ways. The families are no longer able to enter the classrooms to drop off or pick up their children, thereby limiting the daily communication and interactions with staff on how their children are doing. Families opportunities to engage and interact with other families has also been altered, resulting in a sense of loss of community and support among parents.

The purpose of this study was …

The Role Of Hardiness And Autonomy Support On College Student Engagement, Kevin Douglas Cherry

Cal Poly Humboldt theses and projects

The gap between college student enrollment and graduation rates remains a problem for college students and administrators. Literature on persistence in college suggests that factors such as hardiness and autonomy support may contribute to student perseverance through degree attainment. The current study focused on these constructs using a framework based on self-determination theory (SDT; Ryan & Deci, 1985). Factors related to student persistence, namely hardiness and autonomy support, were expected to positively predict college student engagement. Furthermore, hardiness was expected to moderate the relationship between autonomy support and college student engagement. College students from a university and a community college …

The Effect Of Quality Of Life On Cardiometabolic Risk Factors In Postmenopausal Women, Chavela Lynn Riotutar

Write Yourself Awake: The Double Pursuit Of Mindfulness Meditation And Writing, Alysia M. Hegg

Cal Poly Humboldt theses and projects

Contemplative pedagogy involves teaching methods designed to cultivate deepened awareness, concentration, and insight. Contemplative practices work to undo the Cartesian mind–body dualism that says that mental phenomena are non-physical, or that the mind and body are distinct and separable. This project focuses on an understanding that our internal world includes communication with one’s self, acts of imagination and visualization, and recall and memory. These internal experiences foster many things, such as compassion and kindness, as well as resilience and sustainability through connection.

“McMindfulness” is a term that refers to when mindfulness is used for self-serving and ego-enhancing purposes. Symptoms of …

"It Kind Of Polishes All Your Flaws Away": Long-Term Experiences With Psilocybin Mushrooms And The Influence Of Set And Setting, Danielle Nicole Daniel

Cal Poly Humboldt theses and projects

This study explores the experiences and motivations of people who take psilocybin mushrooms long-term. Little scholarly attention has been given to the psilocybin experience outside of a clinical setting. Likewise, there is a dearth of research examining the factors that lead to first-time and ongoing experiences with mushrooms. I conducted in-depth semi-structured interviews with 18 informants who have taken psilocybin mushrooms at least 10 times and for over three years. I encouraged open dialog and storytelling to gain a deeper understanding of their mushroom experiences and motivations to take long-term. Using a grounded theory approach, I identified the following patterns …

Do Beaver Dam Analogues Act As Passage Barriers To Juvenile Coho Salmon And Juvenile Steelhead Trout?, Christopher G. O'Keefe

Cal Poly Humboldt theses and projects

In the Pacific Northwest, the human-caused reduction of quality and quantity of freshwater rearing habitat is a limiting factor for Pacific Salmon populations. Beaver dam analogues (BDAs) increase suitable rearing habitat for juvenile salmonids and promote the restoration of critical stream processes. Installing BDAs is an increasingly popular alternative to more intensive restoration techniques, due to the relatively low cost and effort required to install BDA structures. However, widespread installation of BDAs has been slowed by regulatory agencies’ concerns that BDAs may impede fish passage. Few studies have empirically assessed the extent to which BDAs impede fish passage, and no …

Response Of Coastal Ichthyoplankton Assemblages Off Northern California To Seasonal Oceanographic And Climate Variability, Blair M. Winnacott

Cal Poly Humboldt theses and projects

This study analyzed samples collected along the Trinidad Head Line (41°N) to characterize variability in the ichthyoplankton assemblage in coastal waters off northern California from late 2007 through 2019, a period during which a major marine heatwave (MHW; late 2014-16) strongly perturbed the ecosystem. I augmented visual identification with genetic techniques to resolve the species composition of visually cryptic larval rockfishes (Sebastes spp.). While taxonomic composition off northern California was largely similar to studies off Oregon and Washington, and cross-shelf structure and seasonal patterns in species’ abundance were generally consistent with the distribution and phenology of parental stocks, interannual …

Exploring Zosterophyll Relationships Within A More Broadly Sampled Character Space: A Focus On Anatomy, Megan Nibbelink

Cal Poly Humboldt theses and projects

Important constituents of Siluro-Devonian floras, zosterophylls gave rise to the lycophytes. I explore the relationships of 18 zosterophyll species from 16 genera, maximizing sampling of anatomy. Using phylogenetic and phenetic methods, I (1) assess the influence of tree rooting, taxon sampling, and morphological vs anatomical characters on the stability of relationships; and (2) compare phylogenetic and phenetic methods in terms of relationships recovered. Phenetic analyses show sensitivity to taxon sampling and support placement of Renalia among zosterophylls, but do not provide results that are strongly congruent with those of phylogenetic analyses. Phylogenetic analyses demonstrate that taxon and character sampling significantly …

Oral Versus Gastrointestinal Mucosal Immune Niches In Homeostasis And Allostasis, Lina J Suárez, Silie Arboleda, Nikola Angelov, Roger M Arce

Faculty, Staff and Student Publications

Different body systems (epidermis, respiratory tract, cornea, oral cavity, and gastrointestinal tract) are in continuous direct contact with innocuous and/or potentially harmful external agents, exhibiting dynamic and highly selective interaction throughout the epithelia, which function as both a physical and chemical protective barrier. Resident immune cells in the epithelia are constantly challenged and must distinguish among antigens that must be either tolerated or those to which a response must be mounted for. When such a decision begins to take place in lymphoid foci and/or mucosa-associated lymphoid tissues, the epithelia network of immune surveillance actively dominates both oral and gastrointestinal compartments, …
