Schizo-Net: A Novel Schizophrenia Diagnosis Framework Using Late Fusion Multimodal Deep Learning On Electroencephalogram-Based Brain Connectivity Indices, Nitin Grover, Aviral Chharia, Rahul Upadhyay, Luca Longo

Articles

Schizophrenia (SCZ) is a serious mental condition that causes hallucinations, delusions, and disordered thinking. Traditionally, SCZ diagnosis involves the subject’s interview by a skilled psychiatrist. The process needs time and is bound to human errors and bias. Recently, brain connectivity indices have been used in a few pattern recognition methods to discriminate neuro-psychiatric patients from healthy subjects. The study presents Schizo-Net , a novel, highly accurate, and reliable SCZ diagnosis model based on a late multimodal fusion of estimated brain connectivity indices from EEG activity. First, the raw EEG activity is pre-processed exhaustively to remove unwanted artifacts. Next, six brain …

An Aggregation-Based Algebraic Multigrid Method With Deflation Techniques And Modified Generic Factored Approximate Sparse Inverses, Anastasia Natsiou, George A. Gravvanis, Christos K. Filelis-Papadopoulos, Konstantinos M. Giannoutakis

Articles

In this paper, we examine deflation-based algebraic multigrid methods for solving large systems of linear equations. Aggregation of the unknown terms is applied for coarsening, while deflation techniques are proposed for improving the rate of convergence. More specifically, the V-cycle strategy is adopted, in which, at each iteration, the solution is computed by initially decomposing it utilizing two complementary subspaces. The approximate solution is formed by combining the solution obtained using multigrids and deflation. In order to improve performance and convergence behavior, the proposed scheme was coupled with the Modified Generic Factored Approximate Sparse Inverse preconditioner. Furthermore, a parallel version …

Do Games Reduce Math Anxiety? A Meta-Analysis, Pierpaolo Dondio, Viacheslav Filonenko, Mariana Rocha

Articles

In this paper, we meta-analyse the empirical evidence about the effectiveness of game-based interventions to reduce students' level of math anxiety. After performing a search for randomised controlled studies relevant to game-based intervention for math anxiety, 16 experimental studies with a total of 686 participants described in 11 peer-review articles met the selection criteria.A random-effects meta-analysis indicated a small and non-significant reduction of math anxiety (mean effect size ES=-0.32, CI=[-0.64,0.01]). The results were moderated by several factors: non-digital games were more effective, while digital games had a negligible mean effect size of $ES=-0.13$, $CI=[-0.33,0.08]$. The effect size was moderated also …

Articles

The rainfall has an impact on various fields and industries, including transportation, construction, tourism, health, and wildlife preservation. Accurate rainfall prediction is essential for mitigating the negative impact of rainfall on these sectors. However, previous studies on rainfall prediction have been mainly based on datasets from North America, Europe, Australia, and Central Asia, covering different periods. This study proposes using weather datasets covering the past 5 to 10 years to capture recent patterns in weather data. Additionally, the curse of dimensionality can impact model performance and lead to overfitting. Therefore, this study proposes utilizing dimensionality reduction techniques to ensure that …

An Integrated Model For Information Adoption&Trust In Mobile Social Commerce, Fulya Acikgoz, Abdelsalam Busalim, James Gaskin, Shahla Asadi

Articles

ABSTRACT Despite the growing importance of mobile social commerce (ms-commerce), little research has been conducted on the effects of informational and social factors on users’ post-adoption behavior. We, therefore, build on the understanding of mobile social commerce in the UK market and how it affects users’ post-adoption behaviors. Our theoretical model leverages the information adoption model, social support theory, and social influence theory. Data was gathered from 377 ms-commerce users from the UK and analyzed via Partial Least Squares (PLS-SEM). The research findings show that both informational and social factors have a positive impact on information adoption in ms-commerce apps. …

A Descriptive And Visual Analysis Of The North Coast Fall Prevention Survey Data, Mishell Lopez

Cal Poly Humboldt theses and projects

Older adults over 65 will double from 52.4 million in 2018 to 94.7 million in 2060. Among this aging group, falls affect one out of four older adults and are a critical economic concern for our American society, with yearly costs of $50 billion. In older adults, falling can result in negative consequences such as fear of falling, injuries, mobility restrictions, and loss of independence. California has one of the highest costs per fall ($4 billion annually) and a high percentage of adults who have fallen (30.6%) compared to the nation. Moreover, two of California’s northwest rural counties, Del Norte, …

Use Of Foreign Edna Tracers To Resolve Site- And Time-Specific Edna Distributions In Natural Streams, Braden A. Herman

Cal Poly Humboldt theses and projects

Substantial uncertainty in how to interpret eDNA observations motivates a need for a technique to effectively and efficiently measure of system- and time-specific eDNA distributions. Using a technique to robustly calibrate eDNA dynamics in a given system would improve established eDNA methods such as presence and absence and has the potential to refine estimates of organism abundance using eDNA concentration that are less well understood. Particles of eDNA are present in a wide variety of size and type resulting in varying transport dynamics, persistence, decay, among others. This variation likely makes eDNA transport more complex than that of conservative tracers …

Is The Area Postrema Resistant To The Anesthetic Effects Of Ms-222?, Austin T. Csiszar

Cal Poly Humboldt theses and projects

MS-222 is a common fish anesthetic that dampens neural activity by inhibiting neuronal voltage-gated sodium channels (Na_v) required for action potentials. Previous experiments conducted by our lab’s primary investigator using fluorescence calcium imaging in zebrafish neurons resulted in the observation that neurons in the area postrema (AP), a circumventricular organ located in the dorsal hindbrain, displayed prominent fluorescence intensity during MS-222 induced sedation. I used the genetically encoded calcium indicator GCaMP6s to conduct fluorescence calcium imaging with the goal of recording neural activity in the larval zebrafish area postrema and optic tectum to compare the anesthetic effects of …

Does Cleft Repair Surgery Restore Normal Visual And Neural Responses To Infant Faces?, Rachael Leanne Kee

Cal Poly Humboldt theses and projects

Infant faces readily capture our attention and elicit enhanced neural processing, likely due to their evolutionary importance in facilitating bonds with caregivers. Infant facial malformations are associated with a lower degree of parental investment and have been shown to negatively impact early infant-caregiver interactions. Cleft lip or cleft palate is a common facial malformation, estimated to affect 1 in 700 live births worldwide, that is associated with altered visual and neural processing as compared to normal infant faces. Importantly, it is not yet known how craniofacial repair surgery impacts responses to these faces. The current study uses eye tracking and …

Uncertainty, Parenting Attitudes, Risk Perceptions, And Covid-19 Vaccination Intentions, Zoë Royer

Cal Poly Humboldt theses and projects

The COVID-19 pandemic has had a significant impact on the lives of millions of people, particularly parents. Drawing on uncertainty-identity theory and research on intensive parenting attitudes, two studies sought to understand the effects of self-uncertainty, parenting beliefs, and perceived illness and vaccine side effect severity, on parental intentions to vaccinate children against COVID-19. We hypothesized that parents with intensive parenting attitudes would rely on their parenting identity to reduce uncertainty and make decisions about vaccinating their children. The results revealed that parents who perceived illness severity in unvaccinated children as high were more likely to vaccinate their children, while …

Macrolichen diversity and community composition was determined for an area of high botanical interest in the Coast Ranges of Northern California – the Horse Mountain Botanical Area (HMBA) in Six Rivers National Forest. The Coast Ranges have been suggested to have high epiphytic macrolichen diversity, yet detailed site-specific macrolichen surveys are lacking for the area. Here we present comprehensive data on macrolichens of the HMBA integrated with environmental metadata at the landscape level. Twenty 0.4 ha sampling plots were positioned across the varying habitats of the HMBA and macrolichens were intensively sampled from all substrata. Out of 888 total collections, …

The Effects Of Post-Harvest Residue On Plantation Forest Soils And Early Growth Of Redwood And Douglas-Fir Seedlings In Humboldt County California, Robert W. Raibley

Cal Poly Humboldt theses and projects

Forest harvest residue (slash) usefulness has been up for debate among private timberland owners, public land managers, and the timber industry for decades. The disposal of slash, viewed as having low ecological value, has received considerable attention as wildfire risk has made burning it harder. In recent years, forest scientists and ecologists have recognized the importance of decaying wood and its relationship to forest growth and regeneration. At this site in Northern California, we looked at whether forest harvest residue enriches soil near slash windrows through soils coring and lab analyses, looking for primary limited nutrients nitrate (NO₃-N) …

Indigenous Women In Active Drug Abuse Recovery: An Analysis Of Native And Non-Native Programs, Raquel J. Muñoz

Cal Poly Humboldt theses and projects

In general, much has been written on the experiences of prototypical women in drug recovery programs, however there is only a scarcity of research on the experiences of rural women of color in drug recovery programs. Very few Northern American cultures had experience with alcohol before the first wave of European settlers. Responses to intergenerational trauma faced by Native women include substance abuse, depression, anxiety, low self-esteem, suicidal thinking, and more. Due to socioeconomic disadvantages drug and alcohol abuse tends to be a coping mechanism for many Native American women. Drawing on the narratives of ten Indigenous women who are …

Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones

Cal Poly Humboldt theses and projects

Trespass cannabis grow sites, otherwise known as illegal cultivation sites on public lands, are extremely hazardous to the environment and can severely impact wildlife movement and behavior. Trespass grow sites are dangerous to wildlife as they negatively impact the quality of habitat and wildlife behavior through habitat modification, pesticide use, discarding of trash, and poaching on national forests. I researched gray fox habitat selection and habitat use at six different grow sites in the Klamath National Forest and Shasta-Trinity National Forest in northwestern California. I deployed GPS collars on three gray foxes at two of those grow sites and three …

Using Multiscale Ensemble Habitat Models To Identify Wildfire Risk To Habitat For An Iconic Forest Species, Logan Baker Hysen

Cal Poly Humboldt theses and projects

Large and severe wildfires, exacerbated by climate change and human behavior, are occurring more frequently in many forests across the western United States. While wildfire is a natural part of most terrestrial ecosystems, rapidly changing fire regimes have the potential to alter habitat beyond the adaptive capabilities of species. Spatial assessments of wildfire risks to species habitat may allow managers to pinpoint locations for management activities. To illustrate this, I spatially assessed wildfire risk within habitat that supports the nesting activity of the federally threatened northern spotted owl (Strix occidentalis caurina) in the California redwood coast ecoregion. To …

College Students' Autonomy, Self-Regulation, And Academic Self-Efficacy During Covid-19, Madelynne J. Avila

Cal Poly Humboldt theses and projects

The Coronavirus disease 2019 (COVID-19) forced college students to endure challenges that were unusual in the typical university environment. As self-determination theory, self-regulated learning theory, and social cognitive theory would suggest, college students’ need for satisfaction of autonomy and the ability to apply self-regulation may have been neglected due to COVID-related stressors (SDT; Ryan & Deci, 2000; SRLT; Zimmerman, 2012; SCT; Bandura, 2005). College students from a university (N = 94) participated in an online survey regarding their autonomy, self-regulated learning abilities, academic self-efficacy, and COVID-related stress. Using a moderated mediation model, the current study predicted that self-regulated learning …

Nothing About Us: Three Models Of Disability In Three Works Of Literary Fiction, Mary Lipiec

Cal Poly Humboldt theses and projects

This project explores how the three umbrella models of disability (medical, functional, and social) are shown in several disabled characters from three novels published after the passage of the Americans With Disabilities Act: Parable of the Sower by Octavia Butler, The Fault in Our Stars by John Green, and Good Kings, Bad Kings by Susan Nussbaum. Through the utilization of literary analysis from a cultural studies perspective, this project shows that the models of disability, despite the various flaws in their respective designs, prove to be useful lenses to see disability through, both in these novels and in real life, …

Seasonal Growth, Movement, And Survival Of Juvenile Coho Salmon (Oncorhynchus Kisutch) Utilizing Restored Rearing Habitat, Monica S. Tonty

Cal Poly Humboldt theses and projects

The Scott River supports the most robust population of threatened Coho Salmon Oncorhynchus kisutch remaining in the Klamath River basin. Even in the Scott River, low quality and restricted extent of juvenile rearing habitat limits the Coho Salmon population to a small fraction of historic abundance. To support persistence and recovery of Scott River Coho Salmon, the Scott River Watershed Council (SRWC) has constructed a portfolio of restoration projects to improve juvenile rearing habitat, including beaver dam analogs (BDAs). The Scott River BDAs were the first implemented anywhere in California. This study compares juvenile Coho Salmon responses associated with production …

Finding A Nexus Between Qualitative Education And The Intellectually Challenged Children In Nigeria: The School Libraries As Rescue Agents, Monisola Adebanke Osoba, Kolawole Akinjide Aramide, Adesola Faustina Oyesiku

Library Philosophy and Practice (e-journal)

The intellectually challenged children (children with intellectual disability) suffer from a condition which limits their capacity to learn and function in the society. Ensuring qualitative education for this category of children is still an herculean task in Nigeria as at today. Such children suffer from poor memory and have difficulties with abstract thinking and problem solving. Because the conventional educational system is built on skills such as comprehension, memory, abstract thinking and problem solving, intellectually challenged children are at a disadvantage of being excluded in an inclusive education system. In special education, teaching intellectually challenged children have over time evolved …
