Faculty, Staff and Student Publications

INTRODUCTION: The protocols and criteria used for adrenal venous sampling (AVS) differ across centres. There are no studies from the Indian subcontinent describing AVS-based outcomes in primary aldosteronism (PA). We aim to describe our experience from a single centre.

METHODS: Retrospective records from 2018 to 2020 of patients with confirmed PA who underwent AVS were reviewed. Clinical, imaging, AVS data and outcomes (as per PASO criteria) were recorded. AVS was performed by sequential sampling with cosyntropin stimulation with intraprocedural cortisol and cut-off of selectivity >5 and lateralization >4 by a single radiologist.

RESULTS: Fifteen patients with median age of 50 …

Antimicrobial Activity Of Plasma Rich In Platelets (Prp) On The Ocular Microbiota Of Healthy Horses From Minas Gerais, Luis E C Torres, Camilo O Florez, Jéssica G Oliveira, Giovanna D Vieira, Ilza S Ribeiro, Kelly M Keller, Fabíola O P Leme, Priscila Fantini, Renata P A Maranhão

Faculty, Staff and Student Publications

In equine ophthalmology, ulcerative keratitis is among the most common conditions and, in general, arises as a consequence of some trauma suffered. Secondarily, subsequent contamination by pathogenic or resident bacteria of the horse's ocular microbiota may have undesirable consequences. Under physiological conditions, the normal microbiota coexists with the immune status of the host, serving as a barrier, ensuring the health of the ocular surface, and inhibiting the proliferation of pathogens. However, in the imbalance of immune barriers, the normal microbiota can become pathogenic and lead to infection, acting as an opportunistic agent. The present study aims to demonstrate the antimicrobial …

Assessing The Relationships Between Direct And Vicarious Exposure To Healthcare Discrimination And Erasure, Mistrust In Healthcare, And The Healthcare Utilization Behaviors Among Transgender And Gender Independent Individuals, Kyle L. Mason

Theses and Dissertations

Healthcare inaccessibility through direct exposure (i.e., personal) to myriad forms of gender identity-related discrimination and erasure among the Transgender and Gender Independent (TGI) population has been documented by prior studies. The myriad barriers that individuals who embody TGI identities encounter to accessing healthcare are associated with the underutilization of healthcare, which may further exacerbate the health disparities that exist between this population and cisgender individuals in the United States (U.S.). Although the impacts of the harm that direct exposure to healthcare discrimination and erasure may have on TGI individuals are known, their exposure to such harm vicariously (i.e., through observation …

Exosomal Lipid Biomarkers Of Oligodendrocyte Pathology To Predict Scoliosis In Children With Cerebral Palsy, Nune Darbinian, Emily C Sparks, Armine Darbinyan, Nana Merabova, Tamara Tatevosian-Geller, Katie Calaku, Sarah Bachman, Huaqing Zhao, Shohreh Amini, Laura Goetzl, Solomon P Samuel, Amer Samdani, Michael E Selzer

Faculty, Staff and Student Publications

INTRODUCTION: Cerebral Palsy (CP), the most common cause of disability in children, is phenotypically heterogeneous. Approximately 20% of cases develop severe scoliosis. A pathological hallmark of CP is periventricular leukomalacia (PVL), which is due to dysmyelination, suggesting the possibility of a lipidomic abnormality. Risk factors for CP include perinatal hypoxia, prematurity, multiple gestation, ischemia, infection, and maternal alcohol consumption. There is evidence for low serum levels of omega-3 (ω-3) fatty acids in CP patients, and separately in idiopathic scoliosis. Many effects of free fatty acids (FFAs) are mediated via specific G protein-coupled free fatty acid receptors (FFARs), which play essential …

Maternal Blood Lipid Biomarkers Of Oligodendrocyte Pathology To Predict Fetal Alcohol Spectrum Disorders, Nune Darbinian, Emily C Sparks, Armine Darbinyan, Nana Merabova, Gabriel Tatevosian, Ekaterina Vadachkoria, Huaqing Zhao, Shohreh Amini, Laura Goetzl, Michael E Selzer

Faculty, Staff and Student Publications

INTRODUCTION: Up to 9.9% of children have fetal alcohol spectrum disorders (FASD), the most frequent cause of intellectual disability in the US. FASD may involve abnormal brain development, including dysmyelination, suggesting abnormal development of oligodendrocytes (OLs), which make myelin and are rich in lipids. Indeed, low serum levels of omega-3 fatty acids (ω-3) have been reported in FASD. Free fatty acids bind to specific receptors (FFARs). We have isolated cell type-specific fetal brain-derived exosomes (FB-E) from maternal blood and sampled their contents to search for lipid-related biomarkers that predict FASD.

METHODS: Blood samples were collected from two groups of pregnant …

Documenting Range Expansion Of Two Invasive Tick (Acari:Ixodidae) Species In Eastern South Dakota, Braden Wojahn

Dissertations and Theses

This project documents the expanded zoogeographic ranges of the blacklegged tick (Ixodes scapularis) and lone star tick (Amblyomma americanum) within eastern South Dakota. Ticks are important when considering a “One Health” approach, as many species are competent vectors of zoonotic pathogens causing human diseases and conditions such as Lyme disease, tularemia, rickettsia, and alpha gal syndrome. The research involved constitutes two steps. First, tick surveillance was conducted in eastern counties of South Dakota, spanning March 2021 through August 2022. Surveillance took place along edge habitat at recreation areas, state and public parks, wildlife management areas and refuges, and other natural …

Research On Cloud Manufacturing Service Recommendation Based On Graph Neural Network, Minghui Li, Xiaoqiu Shi, Yuqiang Shi, Yong Cai, Xuewen Dong

Faculty, Staff and Student Publications

There are an increasing number of manufacturing service resources appeared on the cloud manufacturing (CMfg) service platform recently, which leads to a serious information overloading problem to the enterprises that need these resources. To tackle this problem, a graph neural network-based recommendation method for CMfg service resources is proposed, which effectively overcomes some limitations of the traditional recommendation methods. Specifically, we first use different similarity calculation methods (e.g., Cosine similarity, Pearson correlation coefficient, etc.) to calculate the similarities between different resources based on the feature information of CMfg service resources. A resource graph dataset is accordingly established. A graph neural …

Resurrecting 'She Asked For It': The Rough Sex Defence In Canadian Courts, Elizabeth Sheehy, Isabel Grant, Lise Gotell

All Faculty Publications

According to rape crisis centres and women’s shelters in Canada, the US and the UK, women are reporting extreme levels of violence by men who rape them, including strangulation—a particularly dangerous form of violence that is highly predictive of femicide. At the same time, accused men are deploying the “rough sex” defence when the victim—nearly always a woman—has suffered bodily harm or even death as a result of the accused’s actions. This defence is used to suggest that the woman enjoyed strangulation, bondage or other violence as part of “sex play”, inviting judges and jurors to find that she either …

Master of Science in Nursing Family Nurse Practitioner

Do distraction techniques provide adequate pain management in the pediatric population? If so, what is the importance of this topic? Children can develop negative emotional connections to healthcare workers and procedures if they are constantly put through painful experiences. Making these experiences less painful can ensure better healthcare for the future.

Identification With All Of Humanity, Uncertainty, And Beliefs Toward Animals, Andrea Michelle Wilson

Cal Poly Humboldt theses and projects

The current study aims to expand on the human-animal relations literature through a social identity lens, using 231 participants recruited from Amazon’s Mechanical Turk. Americans consume large amounts of meat, yet many people feel morally conflicted by enjoying meat, yet killing animals. These feelings can be tied to one’s identity, through identifying as a vegetarian, meat-eater, or animal lover. Humans tend to attach themselves to a social group, act on behalf of that group’s norms and values, and use their groups to reduce feelings of uncertainty by adopting group normative attitudes and behaviors. People who identify strongly with all of …

Diversity Among University Students In The U.S.: An Analysis Of Student Ethnic Group Preferences And Its Impact On Campus Diversity Perceptions, Joseph Pang

Cal Poly Humboldt theses and projects

Diversity has become a focal point in conversations in higher education in the United States (Nunes, 2021). University systems have employed Diversity, Equity, and Inclusion initiatives to recruit more diverse campus populations (e.g., University of California Board of Regents, 2007). However, this increased number of diverse students prompts the need to better define what diversity looks like on campus and factors that contribute to existing intergroup relations among Black, Indigenous, People of Color (BIPOC). Intergroup contact theory posits that prejudice can be reduced by having groups engage in contact under specific conditions. However, BIPOC have historically been segregated and forced …

Host-Microbe Interactions In Non-Native Estuarine Anemones: Biogeography And Temperature, Parker K. Lund

Cal Poly Humboldt theses and projects

Non-native species are increasing in prevalence around the world, resulting in negative economic and ecological impacts. However, the broad distributions of non-native species also offer a system for investigating the response of host-associated microbial communities to environmental factors across a range of ecological scales. At the broadest scale, I investigated the geography of microbial communities in the non-native estuarine anemone Diadumene lineata on the west coast of the United States of America. Across latitudes, microbial community composition was very similar and displayed a high percentage of Klebsiella spp. at all sites. However, the communities in California tended to exhibit higher …

Cal Poly Humboldt theses and projects

As human development continues to expand, wildlife managers are faced with problems arising from human-wildlife conflict. To address conflict, it is vital to identify how animals view the landscape and move across areas of differing land use. On the North Coast of California, Roosevelt elk (Cervus canadensis roosevelti) are widely considered to be a valuable resource but are viewed by some as a nuisance due to economic losses caused by property damage. The aim of this study was to identify suitable habitat and movement corridors for Roosevelt elk across Humboldt and Del Norte counties in northern California. Suitable …

Estimating Black Bear Population Parameters With Spatial Capture Recapture In A High Desert Mountain Ecosystem, Steffen D. Peterson

Cal Poly Humboldt theses and projects

Black bear (Ursus americanus) populations have grown and recolonized historic range in California, and unharvested populations are currently poorly monitored by existing programs. In the Warner Mountains of northeast California, increasing issuance of bear depredation permits has underscored the importance of black bear population monitoring. To study population density, space-use, and demographics of this unharvested population, I established 10 non-invasive sampling clusters, comprising a 3 x 3 arrangement of 4-km² grid-cells, across a 1,464 km² study area and monitored hair snares over five 10-day sampling occasions in summer 2018. Fourteen microsatellite and two sex-specific genetic markers …

Preimplantation Genetic Testing For Neurobehavioral Traits, Peter K. Zeller

Cal Poly Humboldt theses and projects

Differences in behavioral and mental health traits result from unique interactions of genetic and environmental factors. Genetic information has improved along with technological advancements allowing for more data points to be established and increased data resolution. Because of this, there is a greater ability to identify embryos that carry genetic risk. The approach of Preimplantation Genetic Testing (PGT) is routine for certain genetic diseases but has not been widely used for psychiatric or behavioral traits. This paper critically examines the potential application of PGT-P by focusing on one main example, Alzheimer’s disease (AD). AD is the most prevalent form of …

Technical And Economic Feasibility Of A Microgrid For A Fire Station In Humboldt County, California., Nishaant Kumar Sinha

Cal Poly Humboldt theses and projects

Microgrids are emerging as a promising solution to unreliable grid energy. Today, California is not only witnessing grid resiliency challenges from natural disasters such as wildfires, earthquakes, floods and heatwaves, but it is also seeking to green the grid and bring more renewables online. For example, Humboldt County, where this project is focused, has recently experienced an earthquake of 6.4M (on December 22nd, 2022), which shut down the regional grid for ~20 hours.

Microgrid adoption enables critical facilities to operate seamlessly. The Humboldt Bay Fire Station (HBFS) No.1 is one such example, where first responders work to protect citizens against …

Effects Of Ph, Eelgrass, And Settlement Substrate On The Growth Of Juvenile Magallana (Crassostrea) Gigas, A Commercially Important Oyster Species, Johnny S. Roche

Cal Poly Humboldt theses and projects

Worsening ocean acidification (OA), resulting from ongoing absorption of atmospheric carbon dioxide (CO₂) by the oceans, threatens marine life globally. Calcifying organisms, especially their early life stages, are particularly vulnerable; this includes the economically important Pacific oyster, Magallana (Crassostrea) gigas. Uptake of dissolved CO₂ through photosynthesis by seagrasses, like eelgrass (Zostera marina), may benefit calcifying organisms by increasing pH and carbonate availability. I conducted laboratory and field experiments to quantify carbonate chemistry modification by eelgrass and potential mitigation of OA impacts on growth in juvenile Pacific oysters. In the laboratory experiment, daytime …

Carnivore And Ungulate Occurrence In A Fire-Prone Region, Sara J. Moriarty-Graves

Cal Poly Humboldt theses and projects

Increasing fire size and severity in the western United States causes changes to ecosystems, species’ habitat use, and interspecific interactions. Wide-ranging carnivore and ungulate mammalian species and their interactions may be influenced by an increase in fire activity in northern California. Depending on the fire characteristics, ungulates may benefit from burned habitat due to an increase in forage availability, while carnivore species may be differentially impacted, but ultimately driven by bottom-up processes from a shift in prey availability. I used a three-step approach to estimate the single-species occupancy of four large mammal species: mountain lion (Puma concolor), coyote …

The Relationship Between Prejudice Toward Women And Gay Men And The Role Of Self And Identity Threats, Jacob Steven Crocker

Cal Poly Humboldt theses and projects

The purpose of this research is to further examine the underlying mechanisms of why heterosexual cisgender men perpetuate prejudice toward women and gay men. This work addresses this using a combination of precarious manhood theory with work on masculinity threat and heterosexuality threat under a social identity theory framework. Study 1a explored the effect of masculinity threat and uncertainty on cisgender heterosexual men’s prejudice towards women and gay men. Study 1b was operationally the same, except, instead of masculinity threat, heterosexuality threat was paired with uncertainty. As groups, women and gay men may pose unique threats to men’s masculinity and …

Self-Determination Theory And Exercise Performance For Individuals With Autism., Martin Calderon

Cal Poly Humboldt theses and projects

Individuals with Autism Spectrum Disorder (ASD) tend to demonstrate low levels of physical activity and exercise when compared to their developing peers. Low physical activity levels are associated with multiple factors, including lack of understanding of how to perform exercise movements and low intrinsic motivation. Token economy reward systems have shown to be practical in behavior analysis for changing behaviors however, there is limited research on the effects of token economy reward systems in an exercise setting. The purpose of this study was to determine the impact of a token economy board combined with self-determination theory (SDT) on the exercise …

Intrinsic Foot Muscle Training For Medial Tibial Stress Syndrome, Katherine Newsham, Michelle Boyd, Christine Lauber

Clinical Practice in Athletic Training

Medial tibial stress syndrome (MTSS), a common condition in physically active individuals, is widely studied, yet effective and efficient intervention is elusive. We compared the effects of a 2-week neuromuscular-based intervention to the “usual treatment” in a non-randomized trial involving intercollegiate athletes with complaints of MTSS involving soft tissue. The neuromuscular-based intervention focused on relieving trigger points in the deep compartment and improving intrinsic foot muscle (IFM) function. The control group received “usual treatment” that did not include the study exercises, but did include rest, modalities, stretching, and/or strengthening exercises. Pre- and post-intervention measures included pain at rest, during activities …

Risk Factors Of Medial Tibial Stress Syndrome In Active Adolescents: A Validation Case Series, Daniel Delgado, Matthew J. Drescher, Justin P. Young, Zachary K. Winkelmann, Matthew J. Rivera

Clinical Practice in Athletic Training

Current literature reports that an increase in body mass index (BMI), navicular drop, ankle plantarflexion range of motion (ROM), and hip external rotation ROM are key modifiable risk factors in the development of medial tibial stress syndrome (MTSS) in physically active adults. The purpose of this validation case series was to investigate these four measures as risk factors of MTSS in adolescent athletes. In total, 100 cross country, volleyball, and/or basketball athletes (age = 15.89±1.31 years, 54 assigned female at birth) were included. The competitive sports season was the intervention in this case series and all athletes experienced 6 athlete-exposures …

Nature Of Science: Examining Science Teachers’ Knowledge And Their Instructional Practices, Sharon Bramwell-Lalor

Australian Journal of Teacher Education

This case study focused on a university teacher-education course that included NOS content. An adapted questionnaire was used to collect quantitative data on 83 secondary science teachers’ views about three NOS themes before and after completing the course. Qualitative data were collected from eight of the teachers who were observed teaching during their field experience after completing the course. The teachers’ post-course mean NOS scores were statistically significantly higher than their pre-course scores (t (65) =-10.08, p<.001; Cohen’s d = 1.4). Despite the favourable NOS knowledge among the science teachers, low levels of NOS portrayal were observed in their instructional practices. These findings point to some success in explicitly addressing NOS in science education content courses. However, they raise questions about the transferability of teachers’ NOS knowledge into their classrooms. The findings have implications for teacher-preparation programmes regarding durability of NOS knowledge.

Meaningful Application Of The Australian Professional Standards For Teachers: The Role Of The University Appointed Supervisor, Madlen Griffiths, Mandie B. Shean, Denise Jackson

Australian Journal of Teacher Education

: Preservice teachers undertake mandatory professional experience as part of their journey towards classroom readiness and in-service teaching. Supporting them in this process are supervisors who both guide and assess these novices. Central to this assessment are the Australian Professional Standards for Teachers, which need to be rigorously applied to ensure quality teaching graduates. This article investigates the application of these Standards by the supervisors in both their formative and summative assessment. Data are derived from interviews with final year preservice teachers and supervisors in a primary teaching degree course at one Western Australian university. Findings suggest that there is …

‘We Were All Green And Brand New’: Mentoring In Theories Of Child Development For Australian Early Career Preschool Teachers, Emma Ellis, Andrea Reupert, Marie Hammer

Australian Journal of Teacher Education

Three Australian Government commissioned reports from 2011-2017 convey a longstanding child development theory-practice gap in early childhood education. This study explores what informs mentors’ discussions of theories of child development with early career preschool teachers. Grounded in Interpretative Phenomenological Analysis, themes relate to the wide role of the early childhood teacher, variation in initial teacher education, developing teacher identity, emotional connections, and consolidation and extension of university learning of child development theories. Critical discussion of themes from a Freirean perspective illustrates how mentors conveyed experiences of oppression, marginalisation, and liberation. We offer that though the child development theory-practice gap is …

Integrating Tpack In Pre-Service Teachers’ Efl Course: Impacts On Perception, Knowledge, And Practices, Amira Ali, Hanan Waer

Australian Journal of Teacher Education

Most research that has explored integrating the Technological Pedagogical Content Knowledge (TPACK) framework into teacher education programs primarily utilized context-unspecific self-report instruments. This mixed-methods study explored the efficacy of integrating four domains of the TPACK framework in an EFL course on the perception and knowledge of (30) pre-service teachers in an Egyptian university. The study also investigated the effect of the TPACK-based course on participants’ lesson plans and teaching practices. Data collection instruments included a test, a questionnaire, observation checklists, lesson plans, and semi-structured interviews. Quantitative analysis showed that pre-service teachers’ knowledge and perception of PCK, TCK, TPK, and TPCK …

How Is Trauma-Informed Education Implemented Within Classrooms? A Synthesis Of Trauma-Informed Education Programs, Jacolyn Norrish, Tom Brunzell

Australian Journal of Teacher Education

The purpose of this study was to synthesise the content of trauma-informed education programs with a focus on classroom strategies. Programs (N = 20) were identified that focused on primary and secondary schools and were suitable for application in the classroom by teachers. Program materials available in the public domain were collated and the qualitative research method of reflexive thematic analysis was used to explore commonalities and themes in classroom strategies across different approaches. Classroom strategies were aimed at meeting students’ somatic (i.e., ‘bottom-up’) capacities of safety needs, self-regulatory needs, sensory needs, and relational and attachment needs. Classroom strategies also …
