Differences In Hair Significance Among Black And White Women: An Exploratory Study On Black Hair, Yasmine S. Keen

Cal Poly Humboldt theses and projects

In Western culture, standards of beauty are often based on European characteristics that Black women are inherently unable to meet. African American history and anecdotal accounts suggest that hair in particular can have a significant impact on the perception and body image of Black women, though whether that impact is positive or negative is not clear. The current study takes a quantitative approach to examining women’s relationship with their hair. Black women (n = 146) and White women (n = 1,116) participated in an anonymous online survey regarding time devoted to hair maintenance, money spent on hair upkeep, …

Extending The Fossil Record Of The Polytrichaceae (Bryophyta): Insights From The Early Cretaceous Of Vancouver Island, Canada, Alexander C. Bippus

Cal Poly Humboldt theses and projects

Diverse in modern ecosystems, mosses are dramatically underrepresented in the fossil record. Furthermore, most pre-Cenozoic mosses are known only from compression fossils, which lack detailed anatomical information. Lower Cretaceous deposits at Apple Bay (Vancouver Island, British Columbia, Canada) contain a diverse anatomically preserved flora that includes numerous bryophytes, many of which have yet to be characterized. Among them is a polytrichaceous moss that is described here as Meantoinea alophosioides gen. et sp. nov. Meantoinea alophosioides represents the first occurrence of gemma cups in a fossil moss and is the oldest unequivocal record of Polytrichaceae, providing a hard minimum age for …

The Entangled Student: Identity Control Theory And Student Identity, Joshua Smith

Cal Poly Humboldt theses and projects

This study examines the strengths and opportunities in applying the frame of Identity Control Theory (ICT) to understanding the first-year experiences of students in higher education. Through thirty-one semi-structured interviews with undergraduate and graduate students during their first term in the program of study, different components of the ICT model are explored and tested. Results indicate ICT is modestly effective in explaining the first term experience for these students, but could be enhanced through further development in the areas of identity connectedness, identity exploration and resources/resilience. Recommendations for higher education programming and suggestions for a potential research agenda for ICT …

The Positive Effects On Attitude Among High School Students Towards Students With Autism Spectrum Disorder, Mario Castillo-Urbina

Cal Poly Humboldt theses and projects

Inclusion in the classroom requires that the local education agency provide services (i.e., direct, related) to support each student’s needs. The philosophy guiding inclusion is that these services will allow each student to keep pace or catch-up with his or her typically developing peers (Elkins, Van Kraayenoord, & Jobling, 2003). Students’ attitudes towards their peers with disabilities have been researched and reported through the years however, little work has examined these attitudes in a physical education setting (Archie & Sherrill, 1989; Block & Malloy, 1998; Block & Zeman, 1996; Tripp, French, & Sherrill, 1995). Researchers have reported that individuals avoid …

Using Functional Infrared Thermal Imaging To Measure Stress Responses, Julia Tenaya Kandus

Cal Poly Humboldt theses and projects

The stress response reflects a coordinated pattern of physiological changes that serves the adaptive function of increasing an organism’s ability to cope with situations that require action or defense. The changes in blood flow associated with the stress response may be detectable using the relatively new research technique of functional infrared thermal imaging (fITI). The present study was designed to determine the time-course and topography of temperature changes in human faces during the experience of a stressor. Infrared images were taken from 29 female participants while they completed the mental arithmetic component of the Trier Social Stress Test (TSST). Continuously …

Congruency Between Spoken Language And Guidance Beliefs In Early Childhood Programs, Jennifer Mager

Cal Poly Humboldt theses and projects

The language in a child’s environment either supports or weakens the growth of conflict resolution skills. A study using the language sampled from three early childhood educators, (two in family childcare homes and one in a childcare center) found that those in family child care programs reported stronger beliefs that children can solve problems, teachers support the development of problem solving skills, and conflict can create opportunities for learning than was recorded in practice. This was determined with a frequency count of unilateral strategies employed during perceived conflict. The third participant in a childcare center demonstrated congruency between questionnaire-reported positive …

The Effects Of Forest Degradation On Dna Methylation In Central African Songbirds, Andrew K. Wiegardt

Cal Poly Humboldt theses and projects

Environmentally-induced stress can initiate a molecular response through DNA methylation, which can alter gene expression, thereby serving as a mechanism allowing individuals to acclimate to a changing environment within their lifetime. In addition to DNA methylation, the production and release of corticosterone is a physiological mechanism by which birds can cope with acute environmental stressors. To assess how environmental stress impacted DNA methylation and corticosterone, I collected blood and feather samples from three understory avian species (Alethe castanea, Bleda notatus and Pseudalethe poliocephala), along a disturbance gradient in the lowland Guinean rainforest adjacent to the village of …

Chicana Feminist Participatory Action Research: Collaborative Environmental Justice In The Imperial Valley And The Identifying Violations Affecting Neighborhoods Community Development Project, Kristian Michelle Salgado

Cal Poly Humboldt theses and projects

In 2007 in Imperial County, a community-based organization called Comite Civico del Valle (CCV), along with the Department of Toxic Substances, and concerned residents, created the Identifying Violations Affecting Neighborhoods (IVAN). IVAN is a community-based environmental reporting and monitoring system that is built on the idea that residents are the most knowledgeable about their environment and therefore should have a place at the table alongside environmental regulation agencies. For more than a decade, this has allowed residents to better report environmental concerns. However, for many residents there is still a lack of knowledge about how to properly utilize the IVAN …

Effects Of Manual And Mechanical Ammophila Arenaria Removal Techniques On Coastal Dune Plant Communities And Dune Morphology, Monique R. Silva Crossman

Cal Poly Humboldt theses and projects

The removal of invasive species as part of the restoration process can allow natives organisms to rebound. An ecosystem that incurs damages from invasive species is coastal sand dunes, which are dynamic systems. Some coastal sand dunes on the west coast of the United States have been invaded by Ammophila arenaria. The invasive grass, A. arenaria, is thought to alter and stabilize foredune morphology and reduce populations of native species. The objectives of my research are to examine the effects that manual and mechanical A. arenaria removal techniques have on coastal sand dune morphology and vegetative cover over time. …

Stability For A Small Historic House Museum: Drafting A Collection Management Policy For The Trinidad Museum, Alexandra Mackay Cox

Cal Poly Humboldt theses and projects

A museum exists and is defined primarily by its collection. It is therefore important for a museum to manage its collection effectively while preserving it for long-term use. The size and scope of the museum's collection will determine the complexity of its policy. As such, all museums, including small ones, need a well-defined Collection Management Policy (CMP). This policy outlines what and how to collect, defines the development and use of the collection as well as procedures for the care of the collection, the loaning of items and removing of items from the museum's collection. The Trinidad Museum, a small …

Out Of Sight, Out Of Mind: An Analysis Of Household Food Waste In Arcata, California, Jennifer Michelle Domareki

Cal Poly Humboldt theses and projects

A rising demand for healthy and sustainably grown food has become a trend of our time. However, there is dissonance in contemporary awareness about where food comes from and where it ultimately ends up. Globally, one third of all food produced is never used. In the United States alone, approximately 55 million tons of food is discarded each year (Venkat, 2012). This is problematic because food waste has environmental, economic and social costs associated with it. Organic materials accelerate anthropogenic climate changing greenhouse gas emissions by releasing methane as they decompose in landfills. In addition, unused food embodies and thus …

Treatment Wetland Remediation Via In Situ Solids Digestion Using Novel Blue Frog Circulators, Kyle T. Sipes

Cal Poly Humboldt theses and projects

After 33 years of operation with little maintenance, the treatment wetlands at the Arcata Wastewater Treatment Facility (AWTF) suffer from reduced treatment capacity and internal loading issues, leading to reduced performance in recent years. The next NPDES permit for the facility will regulate discharge ammonia concentrations, and internal ammonia loads, associated with accumulated solids in the system, may lead to future regulation violations.

To begin addressing this problem, the City of Arcata entered into a rental agreement with Absolute Aeration to install two Blue Frog circulators in Treatment Wetland 3 (TW3). The goal of this project was to determine if …

Habitats Of Mind: Dhamma, The World, And Mindful Activism, Michael L. Masinter

Cal Poly Humboldt theses and projects

As a Buddhist, teacher, and a graduate student, coming to know the conflicts and misconceptions that stem from partial views and experiences, I have found it difficult to locate where to stand and how to engage. Buddhist teaching and practice (Buddhadhamma) offers a pragmatic approach to an overarching series of questions and a method of practice designed to address them: What is suffering, its origin, its cessation, and the way leading to its cessation? These are the Ariya-sacca, the four noble truths (or four ennobling realities), which can be applied to the arising of suffering anywhere in nature—whether internal (mind/culture) …

Does Developmental Task Disruption Mediate The Link Between Childhood Adversity And Psychopathy?, Kali C. Williams

Cal Poly Humboldt theses and projects

Research has linked adult psychopathy with abuse or neglect in childhood; however, less is known about how it relates to other adverse childhood experiences. The prevention of psychopathic traits may be possible if the issue is examined from a developmental psychopathology perspective, which attempts to understand how early experiences and disruptions in stage-salient tasks may contribute to pathological behavior. ACEs may disrupt the attachment bond between child and parent and continue to impact adult relational functioning, via cognitive templates of adult attachment styles and difficulties with emotion regulation.

This study examined whether ACEs were related to psychopathic trait scores in …

Dinjik Enjit Nerrzhrii (We Are Hunting For Moose): An Evaluation Of Tribal Co-Management In The Yukon Flats, Interior Alaska, Kelda E. Britton

Cal Poly Humboldt theses and projects

Gwich’in People of Interior Alaska have historically exercised self-governance in the Yukon Flats to protect traditional and customary use practices. A number of factors have challenged Gwich’in self-governance: land ownership in rural Alaska being under multiple jurisdictions, which has created complicated parameters for management of fish and wildlife; and the legal history of the Alaska Native Claims Settlement Act (ANCSA), which has created an arbitrary and fragmented management system. Despite these challenges, Alaska Native communities have been working to reassert their self-governance over important lands and resources. One example is the co-management arrangement between the Council of Athabascan Tribal Governments …

Increasing Uninterrupted Walking Distance For Students With Autism Spectrum Disorder, Steven R. Hinojosa

Cal Poly Humboldt theses and projects

Students with autism spectrum disorder (ASD) do not engage in an adequate amount of physical activity. Often, students with a Level 2 or Level 3 diagnosis of ASD engage in behavior that may make it increasingly difficult for practitioners to encourage the increase of physical activity. The purpose of this study was to determine if preference assessment increase Uninterrupted Walking Distance in students with ASD. Researchers have demonstrated positive outcomes on physical activity levels when students are given the opportunity to choose their most preferred physical activity as a reinforcement. Results from this study showed statistically relevant walking data when …

The Effect Of The Loss Of Lgl1 In Murine Neural Progenitor Cells On Mapk Signaling And Proliferation, Monique R. Lacourse

Cal Poly Humboldt theses and projects

Glioblastoma is an incurable, aggressive, and highly invasive type of brain tumor that harbors tumor initiating cells characterized by disrupted polarized cell divisions. A cell polarity gene lethal (2) giant larvae 1 (Lgl1) has been implicated in gliomas and is a tumor suppressor initially identified in Drosophila with roles in proliferation. The loss of Lgl1 in Drosophila activates the MAPK protein kinase JNK and the Ras pathway and therefore its downstream kinase ERK, a transcription factor modulator. Furthermore, when Lgl1 is knocked out in mice, a phenotype similar to glioma is seen. Loss of the human form of …

Jeweled Spider Flies (Eulonchus Tristis) Are Important Pollinators Of Iris Bracteata, A Rare Siskiyou Mountain Endemic, Jean-Paul E. Ponte

Cal Poly Humboldt theses and projects

Little is known about the pollination biology of the Pacific Coast Irises (Iris: series Californicae, hereafter PCI), especially who visits and pollinates their flowers. In general, Iris flowers are considered bee-pollinated, however, flies in the genus Eulonchus (Acroceridae) are known to visit some PCI members. Therefore, I assessed the relative importance of Eulonchus and other insect visitors to the pollination of a rare PCI species native to the Siskiyou Mountains, I. bracteata.

Methods. I quantified pollinator importance for all flower visitors at sites in northern California and southern Oregon as the product of average visit rate and …

Current Balance Levels In Deaf And Hearing Impaired Children, Megan E. Wink

Cal Poly Humboldt theses and projects

The purpose of this systematic review of literature is to evaluate the current balance levels in deaf and hearing-impaired children. Children with hearing impairments show balance and motor deficits mainly due to damaged or undeveloped areas of the vestibular system. The auditory sense plays a dynamic role in producing functional movements and motor coordination skills. Researchers founded that motor development skills are especially important to Deaf children because better skills lead to participation in Deaf sports as well as increased opportunities for social interaction. For children born or diagnosed as deaf or hearing-impaired, there is still the opportunity to keeping …

Territorialization Of The Internet Domain Name System, Marketa Trimble

Scholarly Works

A territorialization of the internet – the linking of the internet to physical geography – is a growing trend. Internet users have become accustomed to the conveniences of localized advertising, have enjoyed location-based services, and have witnessed an increasing use of geolocation and geoblocking tools by service and content providers who – for various reasons – either allow or block access to internet content based on users’ physical locations. This article analyzes whether, and if so how, the territorialization trend has affected the internet Domain Name System (“DNS”). As a hallmark of cyberspace governance that aimed to be detached from …
