Drach, Prüss, And The Fifteenth-Century Book Trade, Jonathan Taylor

Extra-Textual Elements

The development of the moveable-type press in the mid-fifteenth century led to the rise of a new industry, the manufacture and trade of printed books. Before this, written works existed as handwritten manuscripts individually produced by scribes.

The printing press allowed works such as the Malleus maleficarum and Fasciculus temporum contained within Portland State University’s codex to be produced in a significantly more efficient manner. The printers of the two volumes contained in the codex, Peter Drach and Johann Prüss, successfully avoided the pitfalls facing early printers to become successful in their trade, and may have actively cooperated in the …

Woodcuts Of Human Oddities In The Fasciculus Temporum, Brady Brick

Fasciculus Temporum

This paper focuses on two woodcut images of human oddities in Portland State University’s edition of the Fasciculus temporum (Prüss, Strassburg, 1490).

One woodcut shows children with birth anomalies affecting their eyes, arms, and legs. The second is of a cynocephalus or dog-headed man. The history and context of these types of images and their significance within the text are both considered. This paper also examines possible medical explanations for the physical anomalies shown in the woodcut images.

A Dynamic Neural Network Designed Using Analytical Methods Produces Dynamic Control Properties Similar To An Analogous Classical Controller, Wade William Hilts, Nicholas Szczecinski, Roger Quinn, Alexander Hunt

Mechanical and Materials Engineering Faculty Publications and Presentations

Human balance is achieved using many concurrent control loops that combine to react to changes in environment, posture, center of mass and other factors affecting stability. Though numerous engineering models of human balance control have been tested, no methods for porting these models to a neural architecture have been established. It is our hypothesis that the analytical methods we have developed, combined with classical control techniques will provide a reasonable starting point for developing dynamic neural controllers that can reproduce classical control capabilities. In previous work, we tested this hypothesis and demonstrated that a biologically-constrained neural controller that replicates human …

School of Music + Theater Faculty Publications and Presentations

Claude V. Palisca (1921–2001) was a prominent American musicologist and music educator. He authored books and articles about Renaissance and Baroque music theory and developments in musicology, but is most widely known as the founder and first editor of the Norton Anthology of Western Music (NAWM) and coauthor of A History of Western Music, the two music history textbooks that are still in use in classrooms worldwide. In this article, we trace Palisca’s first idea of the NAWM’s structure, content, and purpose through his writings and activities between the 1950s and late 1970s. The central part …

Strengthening The Capacity To Serve Undocumented Students In A Rural California State University, Carlos Alvarado Sanchez

Cal Poly Humboldt theses and projects

Undocumented students face many obstacles while seeking a higher education degree. As undocumented students apply and are accepted to colleges and universities, they should have the means and resources to complete their higher education degree like all students. An array of strategies can be considered and implemented to have educators and school administrators in higher education be better equipped to serve all students, but specifically undocumented students.

Educators and administrators could continue their acquisition of knowledge base and comfortability about the different implications that surround undocumented students. Therefore, this thesis seeks to examine the efficacy of self-reports on a pre- …

Bringing Climate Change Home To Meet Your Community: Stakeholder Perceptions Of Offshore Wind Energy In Humboldt County, California, Ciara R. Emery

Cal Poly Humboldt theses and projects

As impacts from anthropogenic climate change continue to manifest at global and local scales, communities are increasingly seeking solutions to transition the world away from fossil fuels. Novel renewable energy technologies, including offshore floating wind energy, continue to garner developer interest. Technological success, however, is one small piece in the effort to decarbonize. Project developers are required to engage in political and bureaucratic processes and work with communities where projects may be sited. Balancing community perceptions and needs, as well as permitting and leasing processes, with increasing pressure to decarbonize will be key as the fight against climate change continues. …

Electrification Of Domestic Hot Water To Aid The Integration Of Renewable Energy In The California Grid, Alejandro Cervantes

Cal Poly Humboldt theses and projects

Water heating in residential buildings, also known as domestic hot water (DHW), is the third largest use of energy after appliances and space conditioning. About 90% of the residential buildings in the state use natural gas fueled water heaters, 6% use electricity, and a small percent use liquefied petroleum gas (LPG) or solar water heaters. The current energy use associated with residential water heating is small relative to the total amount of energy consumption in the residential building sector, but it is still a contributor of greenhouse gas (GHG) emissions. Improving hot water systems can be beneficial for bill customer …

Aces & Trauma-Informed Practices For Children & Educators In Early Childhood Education, Ariel L. Llorente

Cal Poly Humboldt theses and projects

Adverse Childhood Experiences (ACEs), consist of the negative and traumatic events that have happened in the early years of a person’s life. The focus here is on childhood trauma. There are many types of trauma, including, physical, sexual and emotional abuse, physical and emotional neglect, exposure to domestic and general violence, as well as household substance abuse, mental illness, racism, parental separation/divorce, and others. Trauma produces both physical and psychological challenges and can disrupt the brain’s development from birth through 18 years of age, causing permanent damage and issues, which we will discuss throughout this thesis. This thesis will explore …

Effects Of Multiple Stressors: Hydroperiod, Introduced Bullfrogs, And Food Limitation On Northern Red-Legged Frogs (Rana Aurora), Lindsey L. Gordon

Cal Poly Humboldt theses and projects

As human activities reach every corner of the globe, climate change, invasive species, habitat destruction, and other stressors causing species’ declines no longer act alone. Climate change has the potential to exacerbate (or mitigate) other stressors (e.g. invasive species or pathogens) affecting amphibian populations. I assessed the combined effects of increased pond drying rates (potential impact of climate change), invasive bullfrogs (Lithobates catesbeianus) presence, and food availability on northern red-legged frog (Rana aurora) survival and body size after metamorphosis by rearing tadpoles under incrementally shortened hydroperiods with and without the presence of invasive bullfrog tadpoles in …

Ethnic Identity And Stress Appraisal As Acculturative Stress Processes Among Armenian Americans, Tsolak Michael Kirakosyan

Cal Poly Humboldt theses and projects

The current study examined the role of ethnic identity and stress appraisal as buffers of the relationship between acculturative stress and wellbeing in a national sample of Armenian American adults between eighteen and thirty-nine years old (N = 159; 62.89% women, 32.08% men; mean age = 25.59, SD = 5.30). Acculturative stress positively correlated with depressive symptoms, and negatively with self-esteem and positive stress appraisal. Stronger ethnic identity affirmation and belonging was related to less depressive symptoms, more positive stress appraisal, and greater self-esteem and life satisfaction. In hierarchical linear regression analyses, acculturative stress significantly predicted more depressive symptoms, …

Effects Of Gap Junction Blockage On Regenerating Body Segments Of Lumbriculus Variegatus, Monica K. Richmond

Cal Poly Humboldt theses and projects

Lumbriculus variegatus is a freshwater annelid that is well known for its regenerative capacity. There are many different factors that affect regeneration in animals. Cell-to-cell communication is a key component of regeneration. Gap junctions are made up of proteins that create a channel that connects the cytoplasm of two cells. Many molecules and ions pass through the gap junctions that can affect regeneration. The purpose of this study was to determine if blocking gap junctions would have an impact on regenerating body segments of L. variegatus and what effects it would produce. L. variegatus was exposed to a known gap …

Lethal Floral Patterns: An Examination Of The Effects Of Orientalism On The Sport Of Muay Thai, Timothy R. Macias

Cal Poly Humboldt theses and projects

Edward Said’s 1987 examination of Orientalism suggests that fields of learning are constrained and acted upon by society, cultural traditions, worldly circumstance, and by stabilizing influences. According to Said these fields of learning work to sustain Western notions of superiority and designate what became considered backwards, degenerate, and uncivilized: the Oriental. Just as the West became the creators and keepers of particular domains of knowledge, specific knowledge concerning martial arts has been altered and modified in ways which reflect the appropriation of martial arts for Western consumption, via the processes of Orientalism. The Orientalization of martial arts preceded in a …

Making Connections To The Filipino American Community Using Culturally Responsive Music Pedagogy, Jared Thomas Coyle

Cal Poly Humboldt theses and projects

Positive connections between school and home have been shown to increase student achievement. Currently there are few resources available in the United States that allow teachers to incorporate aspects of Filipino American culture into their instruction practices. Through the use of traditional children’s songs and singing games, the K-6 classroom music curriculum can serve as an effective vehicle to establish these connections.

In interviews with members of the California Filipino American community, we discussed the musical culture of the Philippines. Informants shared how musical traditions are transmitted and shared in the Philippines and United States. Participants also discussed possible ways …

Assessing Convergent Validity Of The Qabf And Tbh Fa Intake Form With Results Of A Functional Analysis, Melissa Cisneros

Cal Poly Humboldt theses and projects

The current study looked to compare and analyze the convergent validity of the Questions About Behavioral Function (QABF) with Trumpet Behavioral Health’s current form, the Functional Assessment Intake Form. Both forms were compared with results gathered from a functional analysis conducted on individuals with identified challenging behaviors (e.g. body dropping and self- injurious behaviors). A multi-element design was used to conduct a functional analysis, and identified functions from the indirect assessments were compared to the results found in the functional analysis. Results indicated that there was no correspondence between the indirect assessments used with the results from the functional analysis. …

Cal Poly Humboldt theses and projects

Survival of juvenile ungulates is known to be highly variable, yet it is fundamental to understanding the dynamics and trends of wildlife populations. Factors influencing calf survival are poorly understood in northwestern California where Roosevelt elk (Cervus canadensis roosevelti) are known to exist. The objectives of this study were 1) to estimate summer and annual survival rates and determine recruitment rates for Roosevelt elk calves in the area, 2) to evaluate differences in calf survival by examining the effects of individual and population level covariates on summer and annual calf survival, 3) to identify factors influencing the timing …

From Screen To Summit: An Investigation Of Claims About Social Media Use For Outdoor Recreation Purposes, Theodora M. Doyon

Cal Poly Humboldt theses and projects

Recent increases in visitation to public lands in the U.S. are often attributed to a rise in social media sharing of outdoor spaces, and particularly to the use of geotagging and hashtagging for location sharing. There are conflicting views on the influence of social media on visitation to public lands, including negative perceptions of social media users, and positive perceptions of social media’s potential to spread information to underrepresented and underserved communities. Due to the growing interest in social media use and its effects on outdoor spaces, it is important to understand how social media use correlates with recreational behavior …

Micronutrient Supplementation In Relation To Hair Loss Syndrome In California Mule Deer, Max W. Marquez

Cal Poly Humboldt theses and projects

The Jawbone deer herd has been monitored on their wintering grounds since the 1950s and recently began decreasing over the last several years. The decline prompted an investigation into the reasons why. Coinciding with the population decline is the appearance of hair loss syndrome and two species of exotic lice. In order to evaluate the effects of hair loss syndrome and the influence of exotic lice infestation, 38 wild does from the herd were used in a modified-before-after-control-impact study. Does were treated with micronutrients selenium and copper via boluses in winter (December 2013-January 2014). Selenium treatment, at a dose of …

Teachers utilized various interactive tools and strategies to teach students in their virtual classrooms. Parental involvement with the child’s education at home increased. Some public school district polices caused greater reductions in student participation than others. Teachers applied various communication strategies to engage students in creative ways while teaching online. This together with curriculum development and assessment design required that …

"The World Has Changed, And The Wiyot Changed With It:" The Socio-Political Processes And Rationale Of Cultural Landscape Decolonization On Wiyot Ancestral Land, Mark C. Adams

Cal Poly Humboldt theses and projects

This thesis examines recent successful efforts by the Wiyot Tribe in Humboldt County, California to resist and reverse forms of settler-colonial oppression with tangible and unprecedented results. The original inhabitants of Humboldt Bay: the Wiyot, and their allies in the local community, have overcome settler socio-political resistance in three contentious, public disputes to preserve and restore tribal sovereignty over ancestral land and culture. While much has been written about the history of the United States as a settler-colonial project, more research is necessary to understand the processes of grassroots decolonization efforts to alter cultural landscapes. Using a combination of feminist …

Understanding Reading In The English Program: An Inquiry Of How Students Are Guided With Advanced Reading Materials, Kelley L. Ellion

Cal Poly Humboldt theses and projects

Reading and writing are connected activities. Research has shown that you cannot truly be successful in one without the other. In post-secondary writing intensive courses, the teaching of reading in regards to advanced academic texts is often forgotten or ignored due to pre-existing conceptions of reading practices. In this project, I have conducted a research study across three (3) FYC courses at Humboldt State University to understand how the teaching of reading is implemented within its FYC program. I specifically study how the reading pedagogy known as the Reading Apprenticeship (RA) framework is used by instructors within their classrooms and …

The Rattle Call: A Female-Specific Vocalization In Steller's Jays, Kachina L. Rowland

Cal Poly Humboldt theses and projects

While the elaborate songs of male passerines are well documented for their role in intrasexual resource competition and mate attraction, vocalizations used in female competition are poorly understood. Research has suggested that the female-specific rattle call of Steller’s jays (Cyanocitta stelleri) is used in competition for access to a territory and mate. I describe structural properties of the rattle call, and compare life history traits of individual females to rattle call occurrence. I used two rates to quantify rattle call occurrence from 20 females: rattles per observation period (RPO), and proportion of observations with a rattle call (POR) …

The Ginger, The Pin-Up, Or The Stepchild? Redheadedness As An Embodied Trope, Morgan Lee Thornburg

Cal Poly Humboldt theses and projects

The study of redheadedness has been largely neglected in the academic community and beyond. Besides a few outdated psychology studies, pop culture books, a handful of student theses, and one dissertation, there has been little investigation regarding how the tropes associated with redheadedness—namely, weakness and unattractiveness in men and unruliness and hypersexuality in women—become embodied. This project considers the way that such tropes are internalized in a variety of “texts”: Scott P. Harris’s documentary, Being Ginger; Marion Roach’s and Jacky Colliss Harvey’s personal narratives; and Tim Minchin’s song (and performance of) “Prejudice,” together with an interview he gave for …
