Productivity And Cost Of A Cut-To-Length Commercial Thinning Operation In A Northern California Redwood Forest, Kigwang Baek

Cal Poly Humboldt theses and projects

Cut-to-length (CTL) harvesting systems have recently been introduced to the redwood forests of California’s north coast. These machines are being used to commercially thin dense redwood (Sequoia sempervirens) stands which tend to form clumps of stems that vigorously sprout from stumps after a harvest. One of the challenges is to avoid damaging residual trees which can decrease productivity, increase costs, and lower the market value of trees. The goal of this study was to evaluate the productivity and costs associated with CTL systems used in a redwood forests and use that data to develop equations for predictions. Time …

Technical Feasibility And Life Cycle Cost Assessment Of A Photovoltaic Array On Trinity Dam, Trinity County, Ca, Caleb Aaron Patrick

Cal Poly Humboldt theses and projects

Public lands owned by the Bureau of Land Management are increasingly being used for photovoltaic (PV) system development. Although numerous policies support PV deployment on public lands, those managed by the Bureau of Reclamation have not been considered for PV development. Hydro-electric embankment dams, both publicly and privately owned, may have the potential to be development sites for distributed PV systems. A technical feasibility report was conducted for a case study of a PV installation on Trinity Dam, Trinity County, CA, and found embankment dams could potentially be feasible development sites. A mounting analysis found that a concrete slab reinforced …

Sex-Specific Habitat Selection Of Rough-Legged Hawks (Buteo Lagopus) Wintering In Western North America, Genevieve Christa Rozhon

Cal Poly Humboldt theses and projects

The rough-legged hawk (Buteo lagopus sanctijohannis) is one of the most under-studied raptor species in North America. As a species that exhibits reversed sexual dimorphism, sex-specific habitat preferences may exist. To investigate rough-legged hawk sex-specific habitat selection preferences, we equipped 17 rough-legged hawks (n = eight females, nine males) with GPS backpacks on their wintering grounds (n = six study areas) during the winter months of 2014 and 2015 in five states in western North America. I analyzed rough-legged hawk habitat selection in relation to sex at four spatial scales: nocturnal roosting site, 50% core range, 95% winter …

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 …

Words To Cook By: Changing Meanings Of Eating Local In Humboldt County, Nora E. Mounce

Cal Poly Humboldt theses and projects

Humboldt County has an active food system of small, sustainable farms and a vibrant cottage food industry. Yet, this system fails to address the needs of a diverse population that struggles with a disproportionate degree of poor health outcomes. In order to understand the unique challenges facing the region’s food system – and how local government and advocacy groups should begin to address healthy food policy - this research thesis analyzes key texts about food, which illustrate the language and ideologies of eating local in Humboldt County. This research thesis found that the concept of eating local – consuming foodstuffs …

Evaluating Socioeconomic Dimensions For A Resilient Shellfish Mariculture Industry In Humboldt Bay: Assessing The Strengths, Vulnerabilities, And Potential Of Humboldt’S Expanding Industry, Wyatt G. Smith

Cal Poly Humboldt theses and projects

For nearly 90 years the shellfish mariculture industry in Humboldt Bay has coexisted with various stakeholder groups and the Bay’s delicate ecology. Presently, the shellfish mariculture industry in Humboldt Bay is composed of six shellfish producing businesses ranging in operational size from small-scale to large-scale. Commercial shellfish production from Humboldt Bay yields over 70 percent of California’s mature, market-sized, Pacific oysters (Crassostrea gigas) and Kumamoto oysters (C. sikamea). Shellfish growers in the Bay also produce seed from Pacific oysters, Kumamoto oysters, and Manila clams (Tapes semidecussata).

As the mariculture industry in Humboldt Bay is …

Dynamic Balance Of Experienced And Novice Rock Climbers, Brian G. Shea

Cal Poly Humboldt theses and projects

Climbing requires heavy use of the upper body muscles in the torso and arms to pull the body vertically or traverse horizontally. The upper body profile of climbers has been characterized, however there is little research that has examined the lower body and its contribution to climbing performance. There are studies that have examined postural control while climbing, but no study has evaluated the dynamic balance of the lower extremities in climbers. For this study, lower body dynamic balance was measured using normalized reach distances of the Star Excursion Balance Test (SEBT). Eighteen adult, indoor climbers (n=12) and non-climbers (n=6) …

Framings Of Nature In Planet Earth Ii And Wild Safari Live, Joshua Gross

Cal Poly Humboldt theses and projects

The percentage of the world’s population living in cities continues to grow, while media technologies become ever more ubiquitous. As a result, the mass media’s role in connecting the general public to the natural world will only increase; the wildlife genre of television may have a particularly large role to play in this regard. Unfortunately, previous authors have argued that the over-dramatized depictions of nature in mainstream wildlife programs may serve to disconnect viewers from the natural world. Scholarship has also not kept up with recent developments in wildlife television, with few authors writing about hugely successful programs like Planet …

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 …

Ecological Role Of Burrowing Sea Cucumbers, Holothuria Arenicola, In Abaco, Bahamas, Liberty Boyd

Harriet L Wilkes Honors College Theses 2010 - 2019

Bioturbators serve as ecosystem engineers, influencing community dynamics of the environments in which they are endemic. Currently, the bioturbator, Holothuria arenicola, a species of burrowing sea cucumbers, is listed as data deficient by the IUCN. These animals may affect the structure and function of seagrass beds, which are critical habitats for various species. To assess the ecological role of H. arenicola , I conducted field surveys, calculated mound, and analyzed mound nutrient levels. I gathered data through monitoring study plots, conducting Bran-Blanquette seagrass surveys (Fourqurean et al., 2001), capturing GoPro video, and collecting samples. Results indicate an insignificant difference between …

I answer this question by evaluating companies in the business, scientific, and health arenas and discuss why and how they have used video to market themselves. Further, I also examine the ways in which technology has grown in the past few decades, and discuss the different types of learning and how video can appeal to each type. With the results of this research, I ultimately conclude that video is the most effective marketing type. as the actually commodity being provided. I defend …

Pollution Sensitivity Of Macrolichens On Southern Live Oak (Quercus Virginiana), Christy Folk

Harriet L Wilkes Honors College Theses 2010 - 2019

Lichens in south Florida are poorly documented. I surveyed macrolichens on the bark of Southern live oak trees (Quercus virginiana) present on the John D. MacArthur campus of Florida Atlantic University in Jupiter, Florida, to establish a baseline and to determine how automobile pollution may impact lichen species diversity and density. Ten randomly-selected trees in each of two study areas (adjacent to Parkside Drive versus mid-campus, away from any road) were surveyed for lichen species diversity and coverage. Fifteen species of lichens were identified using identification keys and chemical spot tests. Lichen diversity was similar in the two areas of …

Harriet L Wilkes Honors College Theses 2010 - 2019

Picture a bright blue ball just spinning, spinning free, dizzy with possibilities. The lyrics in the Grateful Dead’s music reflect key themes such as care for environmental health as well as other natural aspects of life. This thesis demonstrates the connection between the history of the Grateful Dead and the rising effectiveness of the green movement that continues to grow today. I examine how the Grateful Dead has inspired generations of environmental activists from the 1960s to the year 2018. I emphasize that the band has emerged as a leader in promoting sustainable music concerts, performing in venues that strive …

The Death Of Dawn: On The Ethics Of Florida Marine Parks, Taylor L. Leach

Harriet L Wilkes Honors College Theses 2010 - 2019

Over the last 80 years, humans have enjoyed and developed a deep connection to bottlenose dolphins (Tursiops truncates) and killer whales (Orcinus orca), starting in 1938 with the opening of the world's first oceanarium to presentday with the current marine parks in Florida. We have learned an immense amount of information about the intricacies of two of the most charismatic marine mammals in the ocean, and as we learn more about these highly social creatures, the more people are demanding the immediate release of them into the wild. This, however, raises an ethical dilemma: either we release the animals into …

The Fight For Federal Intervention: Why Professional Boxing Needs Uniform Regulation, Raul Muniz

Harriet L Wilkes Honors College Theses 2010 - 2019

While professional boxing is subject to some federal regulation, there is still a call for greater uniformity throughout the states. For example, the variation of state procedures for performance-enhancing drug and post-fight neurological testing present a serious threat to an athlete’s health that can lead to physical impairments or even death. I argue professional boxing regulation should be completely uniform, left to the federal government rather than individual states. I review the regulatory system in professional boxing and show how the lack of uniformity leads to undesirable health, safety, and business practices. Founded on a critical analysis of federalism, the …

Visualizing The Connections Between Three Fields Of Psychology Using Network Analysis, Randhikaa Neelavannan

Harriet L Wilkes Honors College Theses 2010 - 2019

The purpose of this research is to create a visual representation of the relationships and interactions between the fields of personality, industrial/organizational, and human factors psychology. References were pulled from select chapters of two different handbooks, the forthcoming SAGE Handbook of Personality and Individual Differences and the Oxford Handbook of Organizational Psychology, in order to create a network structure that graphically illustrated the connections between the authors and their specific topics. This structure was then compared to a pre-prepared network that was created by hand of the expectations for what the network should look like based solely on the chapter …

Eyewitness Memory: Manner Of Motion In Perpetrator Identification, Jonathan Perry

Harriet L Wilkes Honors College Theses 2010 - 2019

Eyewitness testimony is a common form of evidence in the legal system. People generally identify suspects based on characteristics such as their appearance, clothes, voice, and even writing style. But what if you could identify someone based on the way they move (e.g., the way in which they walk)? To determine if identification based on movement would be practical and legally allowed, I examined the legal implications of identification that pertain to the Fifth Amendment, as well as the appropriate scientific applicability test based on movement. I also conducted an experiment to evaluate the reliability of such identifications based on …

Immoral But Not Illegal: A Defense For Michelle Carter, Kahlil Ricketts

Harriet L Wilkes Honors College Theses 2010 - 2019

Charged with involuntary manslaughter, Michelle Carter was said to have used text exchanges and phone conversations to “coerce” her boyfriend, Conrad Roy, into committing suicide. But is Ms. Carter to blame for Mr. Roy’s death? By delving into the moral concepts of duty and coercion, and theories and case law concerning manslaughter and free speech, I argue that although Ms. Carter’s actions were not morally sound that does not mean that they were illegal and worthy of punishment.

Oh, Say Can’T You See?, Brittany Wallace

Harriet L Wilkes Honors College Theses 2010 - 2019

The United States of America has long prided itself on its values of freedom and justice, but recent movements have pushed back against the notion that all are equal and free under the U.S. flag. Disenfranchised Americans across the country are advocating for everything from racial justice and immigrant rights, to white supremacy and isolationism. These calls for change, no matter their Rightness or Wrongness, call into question the true ideals of the land of the free and the home of the brave. Oh, Say Can’t You See? is a collection of nonfiction essays that examine what it means to …

Meso-Scale Simulation Of Size-Dependent Shear Behavior In Glass Fiber Reinforced Polymer Reinforced Concrete Beams Without Stirrups, Sina Khodaie

Theses and Dissertations

There is extensive experimental evidence of the decrease in the shear stress at failure at increasing effective depths in concrete beams reinforced with glass fiberreinforced polymer (GFRP) bars without shear reinforcement. An important practical implication is that extrapolating strength values from typical laboratory-scaled experiments to design larger members may be misleading. The complexity of the underlying mechanics is reflected in the difficulty of using commercially available numerical tools to accurately estimate shear strength irrespective of beam size. This dissertation presents research on a Lattice Discrete Particle Model (LDPM) based model to simulate the response of scaled slender GFRP reinforced concrete …

The Lost Ones: The Cold War State, Child Welfare Systems, And The Battles Over The Rosenberg Children, Megan Bennett

Theses and Dissertations

The conspiracy case against Julius and Ethel Rosenberg was a formative event in the early stages of the Cold War, but it also set their two sons adrift in a domestic climate which emphasized domestic order but feared communists and those connected to communists within their midst. Michael and Robert Rosenberg’s lives remained in various states of instability from their mother’s arrest in August 1950 until they were adopted by Anne and Abel Meeropol in 1958. The placement of the Rosenberg children with the Meeropols came only after years of upheaval and family strife in which the notoriety of the …

The Kingma System Flute: Redesigning The Nineteenth-Century Flute For The Twenty-First Century, Diane Elise Kessel

Theses and Dissertations

This project investigates the development and reception of the Kingma System flute, designed by Dutch flutemaker Eva Kingma. For some time now, flutists have been honing creative techniques to provide imperfect approximations of what composers have specified, but the Kingma mechanism achieves the exact effects desired with ease. Through her close work with composers and performers, Eva Kingma was able to create a mechanism that is comfortable to play, versatile in performance, and beautifully suited for contemporary repertoire. The Kingma flute is an invaluable tool for performers and an exciting new voice for composers, offering unprecedented musical possibilities and yet …

Acoustic Emission Detection In 304h Stainless Steel Due To Intergranular Stress Corrosion Cracking, Joseph W. Hill

Theses and Dissertations

Storage of spent nuclear fuel has become problematic in past decades due to delayed completion of long-term repositories for various reasons. Temporary storage containers called Dry Cask Storage Systems (DCSS) made of stainless-steel and surrounded by reinforced concrete have been in use but are exceeding their designed usage periods. Defects in canisters can be exacerbated in climates susceptible to high humidity and salinity levels. As inspection and relicensing of DCSS increases, more efficient monitoring techniques could save nuclear facilities valuable time and resources. Crack detection of the canister walls or welds in real time may be possible utilizing acoustic emission …
