Tire-Derived Geo-Cylinders And Polymer Products For Enhancing The Properties Of Base/Sub Base Materials In Pavement Systems, Justin Scott Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

As a critical part of the transportation network, pavements offer a safe means for vehicular traffic. Pavements are subjected to many forms of stress during their service life, and they are susceptible to environment related cracking and failures. Failures can be attributed to poor subgrade, freeze-thaw variations, and fatigue under repetitive axle loadings. Reinforcement products such as tire-derived geo-cylinders (TDGC) which make-up mechanical concrete and geo-polymers have been utilized in civil engineering practice, and this research aims to understand the potential life of tested pavement system components set at displacement limitations when reinforced with TDGCs and geo-polymers from exposure to …

Cortactin Phosphorylation By Casein Kinase 2 Regulates Actin Related Protein 2/3 Complex Activity And Invadopodia Function, Steven Michael Markwell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Malregulation of the actin cytoskeleton enhances tumor cell motility and invasion. The actin-binding protein cortactin facilitates branched actin network formation through activation of the actin-related protein (Arp) 2/3 complex. Arp2/3 complex activation is responsible for driving increased migration and extracellular matrix (ECM) degradation by governing invadopodia formation and activity. While cortactin-mediated activation of Arp2/3 complex and invadopodia regulation has been well established, signaling pathways responsible for governing cortactin binding to Arp2/3 are unknown. In this dissertation we identify casein kinase (CK) 2α phosphorylation of cortactin as a negative regulator of Arp2/3 binding. CK2α directly phosphorylates cortactin at a conserved threonine …

The Principles And Rhetoric Of Autarky: Debate And Decision-Making In Early Colonial Kenya, Ian Michael Ferguson

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study seeks to understand the decision-making process of the colonial government of the East Africa Protectorate by articulating the principles of autarky: financial independence, development, and effective occupation. The principles of autarky, which are both goal and process for the colonial government, strove to bring that government to a state of self-sufficiency, or autarky. These principles created their own rhetoric within official correspondence which dominated the decision-making process. By looking at three different periods, Foreign Office control, the transition to Colonial Office responsibility, and the Soldier Settlement Scheme of 1919, the importance of the principles and rhetoric of autarky …

Cal Poly Humboldt theses and projects

From 1998-2018, over 6,000 migrants have been found dead after attempting to cross into the United States through its southern border; most of the deaths are due to harsh environmental conditions found through the crossing areas. Migrant remains are often found with no belongings or evidence to use to identify the deceased. Forensic anthropologists, medicolegal examiners, and non-governmental organizations such as Humane Borders, Águilas del Desierto [Eagles of the Desert], and the Colibrí Center for Human Rights have worked to recover, identify, and repatriate these remains. To understand the many facets of this process, this thesis explored the relationships between …

Fighting Rape Culture At Humboldt State University: Challenges And Growth In Student Activism, Ariel Rose Fishkin

Cal Poly Humboldt theses and projects

The term Rape Culture is used to describe a culture in which sexualized violence is normalized and encouraged. Resistance to Rape Culture has existed as long as Rape Culture itself. Efforts take on a unique form in institutions of higher education such as Humboldt State University (HSU), in that the organizers of these efforts are often students. I analyzed three efforts to address Rape Culture at HSU with a feminist approach, using participant observation and qualitative interviewing to assess how these programs can be improved for the students organizing them. Take Back the Night is an annual event with a …

Reliability And Validity Of The Humboldt Food Addiction Questionnaire, Sarah R. Taylor

Cal Poly Humboldt theses and projects

Current research shows that foods high in sugar, salt, and fat can illicit addictive responses (Pursey, Stanwell, Gearhardt, Collins, & Burrows, 2014). Although measures of overeating pathology exist, only a few are dedicated to food addiction. Two of these measures are the Yale Food Addiction Scale (YFAS; Gearhardt, Corbin, & Brownell, 2009b) and the Eating Behaviors Questionnaire (EBQ; Merlo, Klingman, Malasanos, & Silverstein, 2009). Given the shortage of food addiction measures, the Humboldt Food Addiction Questionnaire (HFAQ) was developed to supplement the need for additional tools. Recruited from both a university and online, 626 participants completed this study. Reliability of …

Public Perceptions Of Homelessness In Humboldt County, John Thomas Krapf

Cal Poly Humboldt theses and projects

Homelessness is a social and political issue of great importance in the United States. For every 10,000 people in the U.S. 17 are experiencing homelessness (Bishop et al. 2017). Despite being a consequence of structural factors in the economy such as a lack of affordable housing and livable wages, the news media often frames the issue as an outcome of individualistic factors such as deviant characteristics, criminality, and personal flaws like drug addiction and mental illness. This study examines public perceptions of homelessness in Humboldt County. To explore this question, I conducted a content analysis of 94 articles on homelessness …
