Shifting Sands: Social Cues Influence The Long-Term Dynamics Of Snowy Plover Distribution, Jeremy John Pohlman Mr Jan 2020

Shifting Sands: Social Cues Influence The Long-Term Dynamics Of Snowy Plover Distribution, Jeremy John Pohlman Mr

Cal Poly Humboldt theses and projects

Understanding the social and physical factors that influence the temporal and spatial distribution of a species is imperative for successful management. The Western Snowy Plover (Charadrius nivosus nivosus) selects for wide-open stretches of beach; yet within large expanses of ideal habitat, plover populations tend to be aggregated. Recent evidence suggests plovers may prioritize social information over ideal physical factors alone when selecting breeding locations. I analyzed data collected on an individually marked population of Snowy Plovers in Humboldt County, California from 2001 to 2018 to evaluate the influence of physical (beach width) and social (presence of conspecifics) landscape …


Perceptions Of Academic Achievement In A Community College Sample, Devon Burg Jan 2020

Perceptions Of Academic Achievement In A Community College Sample, Devon Burg

Cal Poly Humboldt theses and projects

Self-reported GPA is often used in academic achievement research when gathering GPA as a variable, though it is not always completely accurate. Previous studies have shown that actual GPA affects self-report as those with higher GPAs tend to be more accurate. Those with lower GPAs tend to inflate their self-reported GPA. Race has also been identified as a variable that affects self-reported GPA as White students tend to be more accurate than non-White students. Gender has had mixed outcomes with accuracy of self-reported GPA.

Previous research showing self-reported GPA to be a valid measure of GPA has used samples from …


Mand Training And Prompt Fading: Teaching Yes-No Manding, Jessica M. Kelly Jan 2020

Mand Training And Prompt Fading: Teaching Yes-No Manding, Jessica M. Kelly

Cal Poly Humboldt theses and projects

Language is a collection of verbal skills which allows the speaker to have some control over how others interact with them. Saying the words “yes” and “no” are fundamental language abilities; The words impact the speaker’s environment by communicating acceptance or rejection of stimuli and experiences. Caregivers, teachers, and friends may have to make choices for an individual who cannot respond to yes-no questions. This skill deficit deprives the individual of autonomy and can lead to challenging behaviors occurring in place of clear communication. Applied Behavior Analysis offers techniques to teach language skills such as saying “yes” and “no” in …

What Student Information Do Teachers Find Valuable Enough To Change Their Practices?, Heather Becksted

Cal Poly Humboldt theses and projects

This Teacher Survey study follows-up my school district’s Parent Interview conducted by teachers on children’s interests, parents’ hopes and fears for their children, how the school can communicate with parents, and areas the school can improve. The intent of the district’s Parent Interview was to improve teacher awareness of student and family needs, influence the teachers to scaffold their curriculum to support student needs and become more motivated to be involved with long-term initiatives that could improve student and family support within the district. However, the Parent Interview did not ask teachers about their views of what, if any, Parent …


Micronutrient Supplementation In Relation To Hair Loss Syndrome In California Mule Deer, Max W. Marquez Jan 2020

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 …


"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 Jan 2020

"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 …


Comparing Environmental Dna And Traditional Monitoring Approaches To Assess The Abundance Of Outmigrating Coho Salmon (Oncorhynchus Kisutch) In California Coastal Streams, Emerson Alan Kanawi Jan 2020

Comparing Environmental Dna And Traditional Monitoring Approaches To Assess The Abundance Of Outmigrating Coho Salmon (Oncorhynchus Kisutch) In California Coastal Streams, Emerson Alan Kanawi

Cal Poly Humboldt theses and projects

Environmental DNA (eDNA) has the potential to dramatically increase the information available to managers regarding species distribution and abundance. Collection of reliable survey information on fish abundance is essential to monitor population trends and restoration efforts for endangered and threatened species. In Northern California, coho salmon are a federally listed species and a focus of ongoing monitoring programs and restoration projects. I examined the feasibility of using eDNA to supplement, or replace, traditional outmigrating juvenile coho salmon monitoring approaches currently used at two existing coho salmon life-cycle monitoring stations. Over the spring of 2018 and spring of 2019, I collected …


Ain't No Love In The Heart Of The Mountains: Hip-Hop, Exclusion, And The White Wilderness, Leonard Alexander Henderson Jan 2020

Ain't No Love In The Heart Of The Mountains: Hip-Hop, Exclusion, And The White Wilderness, Leonard Alexander Henderson

Cal Poly Humboldt theses and projects

The expectations of normative behavior in outdoor recreation are often taken for granted and naturalized within dominant cultural narratives about human/nature interactions. In particular, expectations of silence and an absence of evidence of humans and human sounds (anthrophony), are grounded within an understanding of nature and a wilderness/urban paradigm framed by whiteness. Hip-Hop provides an interesting point of analysis for thinking about the binary opposition of wilderness and urbanness. The intersection of Hip-Hop and wilderness is also the starting point for my research. This research aims to speak to just a few ways that white and masculine social norms in …


A Comparison Of Zinc Levels In Runoff From Rubberized Hot Mix Asphalt And Conventional Pavement, Peter A. Duin Jan 2020

A Comparison Of Zinc Levels In Runoff From Rubberized Hot Mix Asphalt And Conventional Pavement, Peter A. Duin

Cal Poly Humboldt theses and projects

High levels of dissolved zinc in water bodies can be toxic to aquatic organisms. There are currently over 40 waterways in California that have on occasion been in exceedance of Clean Water Act minimum toxicity threshold standards for zinc. Recycled tires that contain 1-2% zinc by mass are commonly used in California paving formulations known as Rubberized Hot Mix Asphalt (RHMA). The addition of tires to RHMA increases the zinc content of the pavement in comparison to conventional HMA. This research assesses the zinc content and leaching rate of RHMA in field and laboratory settings to estimate its contribution of …


Constructing Commonmentalities: Toward Collaborative Governance, Knowledge And Subjectivity, Imil Ferrara Jan 2020

Constructing Commonmentalities: Toward Collaborative Governance, Knowledge And Subjectivity, Imil Ferrara

Cal Poly Humboldt theses and projects

Western society’s intractable social and environmental problems arise outside the bounds of classical liberal ideation, challenging the utilitarian rationality, decision-making faculty, and popular legitimacy of our liberal institutions. Through a qualitative analysis of three collaborative, community-based institutions, this study aims to identify and illuminate alternative conceptions and organizational relationships, which transcend liberal shortcomings and succeed precisely where liberal institutions have failed. It draws on Michel Foucault’s account of liberal governance, discourse and subject formation, but employs a complex-systems lens to move from critical deconstruction to intentional normative construction, from radical subjectivism to a collaborative pragmatic realism, and from the critique …


Decay Of Woody Residues As The Counterfactual Treatment To Mobilization For Bioelectricity Generation, Max A. Blasdel Jan 2020

Decay Of Woody Residues As The Counterfactual Treatment To Mobilization For Bioelectricity Generation, Max A. Blasdel

Cal Poly Humboldt theses and projects

Decay of woody debris is a major carbon flux for forests. Decay processes are not well documented in forest modeling frameworks but play an important role in forest carbon cycling and life cycle assessments of forest-derived products. The main drivers of decay are species, vertical location, and climate. A database of literature values for decay by tree species was created to parameterize a larger model of California forestland carbon cycling. A novel methodology was applied to vary these decay values for each species spatially based on climatic drivers of decay. This resulted in decay values for each species and size …


Relationship Of Parent Academic Socialization To Academic Success Among First Generation College Students, Aubrey Pellicano Jan 2020

Relationship Of Parent Academic Socialization To Academic Success Among First Generation College Students, Aubrey Pellicano

Cal Poly Humboldt theses and projects

Research shows that First Generation College Students (FGCS) have lower rates of college degree attainment than their continuing generation peers. Many of these students face challenges navigating social, academic, financial, and administrative domains when working toward a post-secondary degree. Academic self-efficacy (ASE) is an important predictor of academic success in college. Research suggests that parents can influence ASE through parent academic socialization (PAS), which includes academic expectations set by the parents (PAE), parent academic advice (PAA), and parental attitudes about education (PEA). The current study sought to examine the influence of PAS on ASE in FGCS and its subsequent effect …


Lead Me To Lose: How Leaders, Uncertainty, And Competition Influence Weight Loss Intentions In Groups, Jeffrey M. Beaulieu Jan 2020

Lead Me To Lose: How Leaders, Uncertainty, And Competition Influence Weight Loss Intentions In Groups, Jeffrey M. Beaulieu

Cal Poly Humboldt theses and projects

The rates of obesity in the US was 42.4% in 2017-2018. Engaging people’s social identities through leadership may be an effective method to encourage weight loss. The social identity approach to leadership often examines representative and prototypical leadership as of the average group traits or as leaders who are similar to followers. However, exceptional leaders may also be prototypical. The preference for exceptional (ideal) over similar (representative) leaders may lie in the identity function the leader serves. Here, I hypothesized that ideal leaders (e.g., someone who has already successfully lost weight), who embody extreme positive group attributes are most influential …


Age-Specific And Species-Specific Tree Response To Seasonal Drought In Tropical Dry Forests, Emily A. Santos Jan 2020

Age-Specific And Species-Specific Tree Response To Seasonal Drought In Tropical Dry Forests, Emily A. Santos

Cal Poly Humboldt theses and projects

Millions of people live in or depend on ecoregions dominated by Tropical Dry Forests (TDFs), but due to their high accessibility, convenient topography and mild climate conditions their distribution is fragmented with less than 10% of their original extent remaining in many countries. Despite the vast ecosystem services provided by TDFs, including vital water resources in water limited environments, ecohydrological research in this biome has been limited to a small number of short-term investigations. Similar to worldwide trends, the TDF surrounding Bahía de Caráquez (Bahía), Ecuador, has been severely deforested over the past 400 years. The land use history in …


The Rattle Call: A Female-Specific Vocalization In Steller's Jays, Kachina L. Rowland Jan 2020

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 Usual Course Of Thorax Ct Findings Of Covid-19 Infection Andwhen To Perform Control Thorax Ct Scan, Yasemi̇n Gündüz, Mehmet Hali̇l Öztürk, Yakup Tomak

Turkish Journal of Medical Sciences

: COVID-19 infection, a highly contagious disease caused by the SARS-CoV virus, and the World Health Organization declared this increasingly spreading disease as a global public health emergency (pandemic). In the diagnosis of COVID-19, the polymerase chain reaction (RT-PCR) is considered as the reference standard test. In the early stages, thorax CT findings could be present even before the onset of symptoms, thorax CT has quite high sensitivity in COVID-19 patients with false negative RT-PCR results, and it has a great importance not only in diagnosis but also in follow up. We think that it might be beneficial for our …


Chest Ct Features Of The Novel Coronavirus Disease (Covid-19), Furkan Ufuk, Recep Savaş Jan 2020

Chest Ct Features Of The Novel Coronavirus Disease (Covid-19), Furkan Ufuk, Recep Savaş

Turkish Journal of Medical Sciences

A new type of coronavirus (2019-nCoV) is rapidly spreading worldwide and causes pneumonia, respiratory distress, thromboembolic events, and death. Chest computed tomography (CT) plays an essential role in the diagnosis of viral pneumonia, monitoring disease progression, determination of disease severity, and evaluating therapeutic efficacy. Chest CT can show important clues of 2019-nCoV disease (also known as COVID-19) in patients with an appropriate clinic. Prompt diagnosis of COVID-19 is essential to prevent disease transmission and provides close clinical observation of patients with clinically severe disease. Therefore, radiologists and clinicians should be familiar with the CT imaging findings of COVID-19 pneumonia. Herein, …
