Applying Landscape Fragmentation Analysis To Icescape Environments: Potential Impacts For The Pacific Walrus (Odobenus Rosmarus Divergens), Anthony Himmelberger, K E. Frey, Florencia Sangermano

Geography

Sea-ice cover across the Arctic has declined rapidly over the past several decades owing to amplified climate warming. The Pacific walrus (Odobenus rosmarus divergens) relies on sea-ice floes in the St. Lawrence Island (SLI) and Wainwright regions of the Bering and Chukchi seas surrounding Alaska as a platform for rest, feeding and reproduction. Lower concentrations of thick ice floes are generally associated with earlier seasonal fragmentation and shorter annual persistence of sea-ice cover, potentially affecting the life history of the Pacific walrus. In this study, 24 Landsat satellite images were classified into thick ice, thin ice or open water to …

Probabilistic Tracking Of Annual Cropland Changes Over Large, Complex Agricultural Landscapes Using Google Earth Engine, Sitian Xiong, Priscilla Baltezar, Morgan A. Crowley, Michael Cecil, Stefano C. Crema, Eli Baldwin, Jeffrey A. Cardille, Lyndon Estes

Geography

Cropland expansion is expected to increase across sub-Saharan African (SSA) countries in the next thirty years to meet growing food needs across the continent. These land transformations will have cascading social and ecological impacts that can be monitored using novel Earth observation techniques that produce datasets complementary to national cropland surveys. In this study, we present a flexible Bayesian data synthesis workflow on Google Earth Engine (GEE) that can be used to fuse optical and synthetic aperture radar data and demonstrate its ability to track agricultural change at national scales. We adapted the previously developed Bayesian Updating of Land Cover …

A Comparison Of Two Generalizations To The Linear Sampling Method For Inverse Scattering, Yeasmin Sultana, James E. Richie

Electrical and Computer Engineering Faculty Research and Publications

The linear sampling method (LSM) is a very popular method for determining the boundary of an object from the scattered field. However, there are instances where LSM provides the convex hull of the boundary rather than the true boundary. There are two common generalizations to LSM: the Generalized Linear Sampling Method (GLSM) and the Multipoles-based Linear Sampling Method (MLSM). In this paper, the ability of GLSM and MLSM to overcome some of the deficiencies of LSM are investigated. It is found that GLSM may be ideal for imaging thin features of scatterers and that MLSM can provide an improvement over …

The Sociology And Psychology Of Innovation: A Synthesis And Research Agenda For Intellectual Property Scholars, Stephanie Plamondon Bair, Laura Pedraza-Fariña

Faculty Scholarship

Intellectual Property (IP) and innovation law scholarship is generally concerned with the question of how to promote socially beneficial innovation. Until recently, the analysis brought to bear on that question in the literature has been dominated by an individual, rational-actor-centered model grounded in the neoclassical economics tradition. Under this model, individual innovators are assumed to respond to innovation incentives in rational ways, unswayed by their social environments or their own psychology.

Of course, as innovation scholars are beginning to recognize, the road to innovation is much more winding and complex than the straight path from incentive to innovation that the …

Coase And Accommodation: A Reply, Frederick Mark Gedicks

Faculty Scholarship

Written for a Festschrift in honor of Michael Perry, this essay responds to the argument that the Coase theorem refutes the third-party harm doctrine, which holds that the Establishment Clause prohibits any religious accommodation imposing material burdens (“harms”) on those who derive no benefit from the accommodation because they do not engage in the exempted practice (“third parties”). In economic terms, the third-party harm doctrine prohibits negative externalities created by religious accommodations which shift material costs of practicing the accommodated religion to a relatively small number of third parties who practice a different religion or none at all.

Enter Coase, …

Reforming State Bail Reform, Shima Baradaran Baughman

Faculty Scholarship

We are waist-deep in the third wave of bail reform. Scholars, policy makers, and the public have realized that the short period of detention before trial creates ripple effects on a defendant’s judicial fate and has lasting impacts on our system of mass incarceration. Over 200 proposed bail bills are pending throughout the states. This is not the first period of bail reform in America—two previous waves of bail reform in the 1960s and 1980s have both ended in increased pretrial detention for defendants. Some of the recent efforts in the third wave of bail reform have also increased detention …

Actively Achieving Greater Racial Equity In The Law School Classroom, Catherine Bramble

Faculty Scholarship

2020 and 2021 continue to illustrate the pervasiveness of implicit and explicit racism in our society. Less well-acknowledged and recognized is the extent to which Socratic pedagogy also reflects those pervasive racist realities while simultaneously resulting in inferior learning based on a teaching method invented 150+ years ago. Despite this racist and outdated reality, the legal academy has been reluctant to alter the traditional method of teaching. Tangible, empirical evidence obtained from data-driven cognitive learning science research demonstrates that active learning not only improves learning outcomes for all students, but also mitigates the structural effects of racism in the classroom …

Foraging Behavior Of Honeybees Exposed To Mosquito Insecticides, Samantha Marie Diel

Cal Poly Humboldt theses and projects

The main aim of this study was to quantify the effects of mosquito insecticides on honey bee (Apis mellifera), foraging behavior, explicitly assessing the impacts of adult mosquito control practices on honey bee health. The extent to which honey bees are exposed to pyrethrum, pyrethrins, permethrin, and pyrethroids is unknown, as are their effects on honey bee health and vitality. This study sought to answer this question by exposing honey bees to D-Phenothrin with the addition of Piperonyl butoxide (PBO), one of many synthetic pyrethroids widely used against adult mosquitoes to control mosquito-borne diseases. Honey bees were exposed to …

Johnson V. M'Intosh: Christianity, Genocide, And The Dispossession Of Indigenous Peoples, Cynthia J. Boshell

Cal Poly Humboldt theses and projects

Using hermeneutical methodology, this paper examines some of the legal fictions that form the foundation of Federal Indian Law. The text of the U.S. Supreme Court’s 1823 Johnson v. M’Intosh opinion is evaluated through the lens of the Convention on the Prevention and Punishment of the Crime of Genocide to determine the extent to which the Supreme Court incorporated genocidal principles into United States common law. The genealogy of M’Intosh is examined to identify influences that are not fully apparent on the face of the case. International jurisprudential interpretations of the legal definition of genocide are summarized and used as …

From The Edge Of A Rib: Pro-Ana Edgeworking Narratives, Casey Dobbins

Cal Poly Humboldt theses and projects

People who deliberately practice eating disordered behaviors as a lifestyle form digital communities known as pro-ana. Pro-ana identity is constructed through the medicalized frameworks of anorexia nervosa that attempt to maximize weight loss and also manage other eating disorder behaviors such as binging and purging. This thesis examines pro-ana materials requested and produced on websites, Whisper, and Reddit, assembling these discursive and image exchanges into discourses that identify and describe eating disorder pathology and recovery. My ethnographic collection consists of screenshots of written materials and images from websites, Whisper posts, Reddit threads, and a Discord. This thesis examines discursive strategies …

Does Bisphenol-A, An Estrogen-Like Environmental Toxin, Disrupt Expression Of The Neuronal Chloride Exporter Protein During Early Brain Development?, Mayra S. Mendez

Cal Poly Humboldt theses and projects

Bisphenol A (BPA), a manufactured compound found in consumer products, is known to adversely affect early brain development by disrupting normal estrogen signaling. Recently, BPA was reported to suppress expression of a gene encoding the neuron-specific chloride ion transporter, KCC2. Human and animal studies show suppressing KCC2 can cause neuronal and behavioral hyperactivity. Therefore, some adverse effects of BPA may be due to KCC2 suppression and consequent neuronal hyperactivity. This study aimed to determine whether BPA exposure during brain development alters KCC2 expression. A secondary purpose was to evaluate whether a new transgenic zebrafish line, KCC2:mCitrine,could be used to track …

Evaluating Science Communication Efforts And Citizen Scientists' Knowledge Of, Attitude Toward, And Behavioral Intentions Related To The North American River Otter, Karlee D. Jewell

Cal Poly Humboldt theses and projects

Citizen Science (CS) and scientific visual, spatial, and graphic art projects have the potential to engage community members, provide opportunities for advances in scientific literacy, increase interest in science and local environmental knowledge, and elevate pro-environmental attitudes. CS depends upon public participation, and motivation for participation is varied, including participants’ desire to learn something new or contribute to science or scientific knowledge. An effective CS project will be rooted in an understanding of individuals’ motivations for participation, striving to meet those motivations, and effectively evaluating not only the scientific outputs of the project but also whether participants’ motivations are being …

A Guidebook For Adapted Physical Educators: Connecting The Domains Of Learning To Evidence-Based Practices, Kalyn G. Ruland

I created a guidebook for Adapted Physical Educators (APE) as a resource on how they can use Evidence-Based Practices (EBP's) created by The National Professional Development Center for Autism Spectrum Disorder (NPDC on ASD) to meet the Domains of Learning. The goal for this guidebook was to help bridge the gap between educational research and practice in the classroom. EBP’s are a form of research based interventions that are made easily accessible for busy educators. The main audience for the guidebook is Adapted Physical Education Teachers, with a secondary audience of Special Education and general education teachers. This guidebook was …

Characterizing The Relationship Of Lgl1 And Akt In Migration Of Murine Neural Stem And Progenitor Cells, Natalie Pedicino

Cal Poly Humboldt theses and projects

Asymmetric cell division and migration are critical for neural stem cell differentiation and brain development. When these processes are dysregulated in neural progenitor cells (NPCs), developmental defects and diseases like glioma can result. Lgl1 is a tumor suppressor gene that was first characterized in Drosophila neuroblasts (Strand et al., 1994). It is best known for its regulation of asymmetric cell division through its association with the Par complex. The PI3K/AKT signaling cascade is involved in cellular migration and is also regulated by Par signaling. Unpublished data from the Sprowles laboratory suggests a potential role of Lgl1 in migration and other …

Carnivore And Ungulate Responses To Cattle In A Grazed Forest Ecosystem, Rebecca Carniello

Cal Poly Humboldt theses and projects

Habitat disturbance, a leading threat to biological diversity, comes in many forms and can alter the behavior of wildlife and reduce the amount of suitable habitat. Livestock grazing, a form of habitat disturbance, is the most widespread influence on native ecosystems of western North America. Research on the impacts of introduced domestic herbivores on wild carnivores and ungulates varies, and the degree to which wildlife species are affected is often species-specific. I used remote trail cameras to compare the activity patterns of black bears (Ursus americanus), coyotes (Canis latrans), bobcats (Lynx rufus), mountain lions …

Market Surveillance To Support Quality Assurance And Consumer Protection For The Solar Payg Products Market In East And West Africa, Hamidah Naishur Nakimuli

Cal Poly Humboldt theses and projects

Off-grid Pay As You Go (PAYG) solar products have become one of the fastest-growing approaches to providing basic electricity services to off-grid households not only in Sub-Saharan Africa but also in many other parts of the world with limited or no access to the grid connection. However, sustainably growing the PAYG solar industry requires paying close attention to product quality from the point of manufacturing to the end user. This research examines how to best design market surveillance programs that ensure quality in off-grid PAYG solar products and strengthen the implementation and enforcement of quality standards in the off-grid solar …

Degradation And Nitrogen Cycling In The Context Of Biodiversity-Ecosystem Function Relationships In The Inquiline Bacterial Community Of Darlingtonia Californica, Megan Teigen

Cal Poly Humboldt theses and projects

Biodiversity-ecosystem function (BEF) research aims to explain how species and their environments interact with each other. Microbial communities engage in vital biogeochemical pathways in a variety of natural ecosystems, and yet there are large knowledge gaps about the specific metabolic pathways in which they are involved. Degradation specifically contributes to nitrogen cycling globally through the breakdown of large organic nitrogen compounds into small inorganic nitrogen that is necessary for the survival of many other organisms. In this study, I focused on the degradative function of the inquiline microbial communities found within the carnivorous pitcher plant, Darlingtonia californica. Darlingtonia grows in …

A Preliminary Study For The Development Of Free Weight Back Squat Muscular Fitness Reference Norms For Adults Aged 19-29, Eden G. Marquez

Cal Poly Humboldt theses and projects

The barbell back squat is a simple and common resistance training exercise that is used to evaluate muscular fitness. Its use as an evaluative method for muscular fitness in the general population is limited due to a lack of published reference values for this free weight exercise in the general population. This study presents reference values for the back squat muscular fitness in healthy active young adults (aged 19-29). This data is made of 399 subjects (51% male/49% female). Mean ±SD for participants in anthropometric data were 23.1±2.8 years of age, 73.0±12.9 kg weight, 170.6±9.4 cm height, and 25.0±3.4 body …

Escherichia Coli And Salmonella Sp. In Domestic Cattle And Wild Roosevelt Elk: Fecal Pathogens At The Wildlife-Domestic Interface, Emily A. Buck

Cal Poly Humboldt theses and projects

Direct or indirect contact between domestic populations of animals and wildlife carries an inherent risk for transmission of pathogens that cause infectious disease. In Humboldt and Del Norte counties of northern California, ongoing conflict between ranchers and Roosevelt elk groups results from elk use of ranching pastures and pastures on private land. Fecal samples from elk in association with cattle, cattle, and from elk not in known association with cattle were assessed for the presence of bacteria Salmonella enterica and pathogenic Escherichia coli to assess whether association with cattle increases risk of infection for elk. Group identity (one of the …

Hormonal Medications And Partner Odor Preferences, Jeffrey Lee Frederick

Cal Poly Humboldt theses and projects

The ability to recognize kin through the olfactory sense has important survival and evolutionary implications when choosing mates. Failing to recognize kin when making a choice of whom to mate with can lead to an increase in detrimental genetic outcomes in offspring. Previous studies have indicated that normally ovulating heterosexual women and men prefer the body odor of those with dissimilar immune systems than those with similar immune systems. The use of hormonal contraceptives has shown a preference for similar immune system odors. The current study examines whether the use of hormonal medications predicts preference for body odor. Importantly, this …

Prevalence Of Rickettsia Sp. Phylotype G022 And Rickettsia Tillamookensis In Ixodes Pacificus Nymphs From Northern California, Erin Rose Trent

Cal Poly Humboldt theses and projects

Back in 2011 an unknown Rickettsia species was discovered in adult Ixodes pacificus and became known as Rickettsiaspecies phylotype G022. Preliminary analyses placed it among the Spotted Fever Group Rickettsia, indicating unknown pathogenicity. Another Rickettsia species previously found in I. pacificus, R. tillamookensis, was only recently the subject of research efforts after its original discovery in the 1960s. The main focus of this research was to determine the prevalence of phylotype G022 in nymphal I. pacificus to gain further insight into this tick-Rickettsia relationship. The prevalence of R. tillamookensis was also a topic of this …

Putin's Invasion Of Ukraine: What's Religion Got To Do With It?, Mark R. Elliot

Occasional Papers on Religion in Eastern Europe

Summary

• As of February 24, 2022, as Russian air strikes, missiles, and tanks began pouring into an outmatched Ukraine, the Byzantine calculus of symphonia, of a mutually interdependent church and state, devolved into an unholy alliance joining at the hip a predatory Putin and a sycophantic Russian Orthodox Patriarch Kyrill.
• Especially over the past decade Patriarch Kyrill has tied the fate of his church to that of his patron Putin, the same tragic mistake made by the same church in its defense of tsarist Russia in its death throes.
• Since his accession in 2009, and emphatically since Russia’s moves against …

A Comparison Of Forensic Populations Using The Validity Scales On The Mmpi-3, Steven W. Steinert

Master's Theses and Doctoral Dissertations

Examining the impact of different factors influencing the validity of an individual’s self-report during a psychological assessment is important in ensuring valid clinical findings and useful recommendations. These factors are often referred to as response biases. There are multiple types of response bias that can negatively influence the validity of self-reports in clinical assessment contexts. Specifically, individuals undergoing an assessment can be impacted by non-contentbased response bias, overreporting, and underreporting of psychological impairment and/or distress. Minnesota Multiphasic Personality Inventory (MMPI) instruments are amongst the leading tools within professional psychology used to identify response bias. The most recent iteration, the MMPI-3, …

Examining The Intention-Behavior Gap: The Impact Of The Food Environment On The Eating Behaviors Of Low-Income African American Women, Karen Glownia

Master's Theses and Doctoral Dissertations

The current study investigated environmental barriers to the intention-behavior gap. The food environment was examined as a moderator between motivation for healthy living and actual eating behavior. A sample of 55 low-income African American women (M_age = 30.25, SD = 7.46) completed self-report motivation and eating behavior questionnaires. The food environment was measured by the number and proportion of healthy and unhealthy food retailers in one’s neighborhood using ArcGIS mapping software. The results showed that greater motivation was associated with less unhealthy eating when there was relatively equal access to nearby unhealthy and healthy food retailers. When given …

Repressive Psychiatry As A Means Of Combating Religious Dissidents In The Soviet Union, Oksana Vysoven, Nina Brehunets, Tetyana Lohvynyuk

Occasional Papers on Religion in Eastern Europe

The article highlights the impossibility of the coexistence of modern civilization in conditions of impunity for crimes against humanity, which have no statute of limitations, but due to the lack of punishment and concealment of information it creates even greater crimes. Many of the unjustly convicted political prisoners have been rehabilitated since the condemnation of Stalin's cult of personality and his crimes in Soviet Ukraine since 1956. As a result of the mass rehabilitation of political prisoners, the regime gained serious opposition, some of whom сonsisted of evangelical Baptist communities who advocated genuine freedom of conscience. The Soviet regime used …

Why Do I Teach Math This Way: A Qualitative Examination Of How Teacher Experiences Impact The Implementation Of Instructional Practices, Carrie A. Heaney

Master's Theses and Doctoral Dissertations

Since the 1960s, there has been an effort among the mathematical education community to shift instructional practices from a focus on arithmetic, memorizing rules, and completing practice worksheets to instructional practices that allow students to see mathematics as content that requires thinking and pattern explorations. Many mathematics teachers have not fully embraced these shifts in instructional practice. This study aimed to examine secondary mathematics teachers’ experiences and how those experiences connect to teachers’ implementation of student-centered instructional practices in the lessons they design. This qualitative study utilized a grounded theory approach to examine how a teacher’s experiences as a student …
