Intercropping And Denisity Impacts In A Lettuce And Chard Agroecosystem, Sophia Moser

Master of Science in Environmental Sciences and Management Projects

Conventional agriculture that uses machinery management, synthetic fertilizers, and pesticides, is a contributor to greenhouse gas emissions, reduction of biodiversity and soil health. Agroecological methods, such as intercropping, have the potential to make farming more sustainable, financially feasible and to be implemented on a large scale. Gaps in agricultural research have led to limited information as to how intercropped arrangements can be adapted to be as productive as conventional systems. This research evaluates the ecological and economic performance of a lettuce and chard agroecosystem, specifically investigating the impact that density and intercropping has on plant productivity and profitability. Both species …

A Values-Based Self-Management Program For Undergraduate Students With Remote Delivery: Looking At Emotion Regulation, Sara Elizabeth Johnson

Graduate Theses/Dissertations

College students face significant levels of stress (American College Health Association, 2019) and recent data suggests a high prevalence of diagnostic-level mental health concerns being reported by students and treated by mental health professionals (Blanco et al., 2008). College counseling centers are thus facing an increase in demand for services, creating a growing need for innovative treatment options to flexibly accommodate the demand (Center for Collegiate Mental Health, 2016). In response to the unique needs of college students, Acceptance and Commitment Therapy (ACT)-based interventions have received support for their use in increasing wellbeing in engineering students and graduate students (Abiadbe …

Stimuli Responsive Dye-Containing Peg-Pla Block Copolymer Micelles And Computationally Assisted Design Of A Stapled Peptide Bundle, Tyler L. Odom

Graduate Theses/Dissertations

In this thesis, I report the preparation and characterization of dye-containing PEG-b-PLA block copolymer micelles and the computational design of a novel coiled-coil peptide bundle. The PEG-b-PLA micelles encapsulate hydrophobic molecules into their core and have strong potential as nanocontainers or delivery vesicles. In theory, these internalized molecules can be released upon exposure to mechanical forces that disrupt the micellar structures. This force-responsive nature is one of the inherent properties of micellar systems. However, there is a stark lack of research that utilize this property in applications. Along those lines, I have studied the behavior of …

The Co-Requisite Collaboration: Building Self-Confidence, Self-Efficacy, And Rapport Through Dialogue Journals In A Basic Writing Course, Timothy Jacob Pyatt

Graduate Theses/Dissertations

Research on dialogue journals has grown in the last fifty years, but a gap exists in understanding how and why these dialogue journals work. During the fall of 2020, I conducted a study utilizing quantitative data to examine how dialogue journals impact student’s self-confidence, self-efficacy, and rapport. The data has confirmed that dialogue journals are effective classroom tools and that various aspects such as word count and purpose can be impacted in connection to student’s perceptions of themselves. This project responds to the gap in the literature and provides data to support how and why dialogue journals promote growth in …

Career Development In Sport And Leisure: An Application Of Social Cognitive Career Theory, Nicole Sellars

Dissertations

Utilizing Social Cognitive Career Theory (Lent et al., 1994) this research aimed to determine perception differences related to sport and leisure management employment for undergraduate students in related degree programs with a specific focus on the minority groups of women and People of Color (POC). Given the lack of diversity in sport and leisure enrollment and employment (Adriaanse, 2016; Massengale & Lough, 2013; Shropshire, 2004; Vianden & Gregg, 2017), this research sought to explore whether gender and/or race were predictors of feelings of self-efficacy, outcome expectations, barriers, and supports. An electronic survey was distributed to sport and leisure management undergraduate …

The Impacts Of Aging, Sedentarism, And Exercise On Neurotrophic Factor Expression And Innervation In The Heart And The Effects Of Treatment With Α-Cgrp On Heart Function, Gabriel Almeida Alves

Dissertations

Neurotrophic factors (NFs) are important molecules responsible for development, differentiation, regeneration, and maintenance of new and mature neurons. Neurotrophic factors act as neurocytokines and may assist with the regulation of axonal and dendritic arrangements and synaptic plasticity between neurons themselves or with other non-neural target tissues. In this study, we analyze the levels of two NFs: glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF). Cardiomyocytes produce these neurotrophic factors which assist with the innervation pattern of the heart. The heart is innervated by the two branches of the autonomic nervous system; namely the sympathetic nervous system and …

Induced Cell Proliferation Initiated By Roxarsone (Rox) Is Not Sufficient To Prevent Acrylamide Impairments In Beas-2b Cells., Brett Lavigna Afiwa Tapoyo

Theses (2016-Present)

Natural environmental contaminants and xenobiotic compounds consumed by humans are likely to be deleterious to human health. This study evaluates the effects of the organoarsenic compound roxarsone and the organic compound acrylamide on BEAS-2B cells. Arsenic occurs naturally in the environment in inorganic and organic forms. Inorganic arsenics are carcinogenic to humans. Organic arsenics (organoarsenics) are less toxic, yet their level of toxicity cannot be ignored. Roxarsone (4-hydroxy-3-nitrobenzenearsonate) is a compound used as a poultry feed additive and antimicrobial agent. It promotes cell proliferation and possesses angiogenesis properties. Roxarsone (ROX) can be found in chicken breast meat; along with a …

Too Cynical To Reconnect: Cynicism Moderates The Effect Of Social Exclusion On Prosociality Through Empathy, Bryan K. C. Choy, Kimin Eom, Norman P. Li

Research Collection School of Social Sciences

Extant findings are mixed on whether social exclusion impacts prosociality. We propose one factor that may underlie the mixed results: Cynicism. Specifically, cynicism may moderate the exclusion-prosociality link by influencing interpersonal empathy. Compared to less cynical individuals, we expected highly cynical individuals who were excluded to experience less empathy and, consequently, less prosocial behavior. Using an online ball-tossing game, participants were randomly assigned to an exclusion or inclusion condition. Consistent with our predictions, the effect of social exclusion on prosociality through empathy was contingent on cynicism, such that only less-cynical individuals responded to exclusion with greater empathy, which, in turn, …

Gender Disparity In Host Responses To Hepatitis B-Related Hepatocellular Carcinoma: A Case Series, Rukaiya Bashir-Hamidu, Divya Chalikonda, Hie-Won Hann

Division of Gastroenterology and Hepatology Faculty Papers

Chronic hepatitis B virus (HBV) infection is one of the most common causes of hepato-cellular carcinoma (HCC), a malignant tumor with high mortality worldwide. One remarkable clinical feature of HBV-related HCC is that the risk of development is higher in males and post-menopausal females compared to other females. Increasing evidence also indicates that the prognosis of HBV-associated HCC may involve gender disparity, with females having more favorable out-comes. The proposed mechanism of this gender disparity is thought to be complex and multifactorial. Attributions have been made to gender differences in behavioral risk factors, host stress, immune response, psychology, metabolic risk …

Methods: A retrospective study of 148 patients diagnosed with uterine serous carcinoma from 1997 to 2016 at two academic medical centers in the Detroit metropolitan area was done. A central gynecologic pathologist reviewed all available slides and confirmed the histologic diagnosis of each case of USC. We assessed the prognostic impact of various clinicopathological parameters on overall survival (OS) and endometrial cancer-specific survival (ECSS). Those parameters included race, body mass index (BMI), stage at diagnosis, …

Translating Risk Information To Protective Action: Examining Household Response To Information About Earthquake Hazards And Risk, Carson C. Macpherson-Krutsky

Boise State University Theses and Dissertations

Natural hazards have been a part of the landscape since its existence, but they are becoming more devastating as they intersect with growing populations and as climate change increases their frequency and intensity. As these changes occur, the need to understand how to reduce disaster impacts becomes paramount. Despite growing concern and increasing costs of disasters over the past decade, household preparedness, which is at the foundation of disaster readiness, has seen little to no improvement. Using two research experiments, we adopt the Protective Action Decision Model (PADM; Lindell & Perry, 2004; 2012) as a framework to investigate what motivates …

Laboratory Measurement Of Electrical And Hydraulic Properties Of Regolith Over Granitic Bedrock, Taylor James Bienvenue

Boise State University Theses and Dissertations

Characterizing water flux within the critical zone (CZ) is essential for a multitude of studies and applications related to irrigation, drainage, water management, and contaminant transport. Trying to measure water flux in the critical zone, specifically in the subsurface, is difficult due to the associated structural heterogeneity and complex interactions taking place between biological, chemical, and physical processes. Current methods (i.e., inferred from soil suction and soil moisture measurements) to characterize water flux within the critical zone can be time consuming and are not directly related to water flux. Recent literature has provided evidence that self-potential (SP) is a promising …

The 4d Living Genome, Julianna Arlene Sherman Goelzer

Boise State University Theses and Dissertations

Over the last few decades great advances have been made in our understanding of gene expression and the human genome. In 2003 the human genome was sequenced for the first time, allowing us to discover its true importance in human health. While sequencing the human genome was a great advance, it ultimately created more questions than it answered. It is known that the genomic sequence is extremely important in genome regulation, however recent studies have shown that the 4D (spatiotemporal) organization and dynamics of the living genome plays an equally critical role in regulation of gene expression. A key factor …

Transdiagnostic Classification Of Behavior In Childhood: Profile Analysis And Interrater Stability, Gary Rempe

Dissertations

There is growing concern among both researchers and practitioners that mainstream psychopathological classification schemes inadequately meet the needs of individuals seeking treatment for mental illness. Recent efforts in childhood psychopathology have sought to derive new diagnostic subgroups that are less susceptible to the heterogeneity and comorbidity issues that have been reported with categories specified in more recent versions of the diagnostic and statistical manual of mental illness. These transdiagnostic subgroups are generated by using unsupervised machine-learning algorithms that separate cases into homogenous groups with information from multiple continuous indicators. This dissertation seeks to expand on this work by exploring natural …

Anxiety, Depression, And Perceived Barriers To Adherence Among Parents Of Pediatric Transplant Patients, Alice Marie Wille

Dissertations

Before being listed for an organ transplant, pediatric patients and families undergo a psychosocial pre-transplant evaluation to determine familial strengths and risk factors that may impact the success of transplant. Adherence is considered to be one of the primary factors in the survival of the transplanted organ and existing research has suggested a link between parental functioning and post-transplant adherence. To better understand the relationship between parental mental health and perceived barriers to adherence, this study examined whether parental symptoms of anxiety and depression significantly predicted parent and patient perceived barriers to adherence in the pre-transplant phase (n=65 parents and …

Special Education Directors’ Perspectives On The Written State Complaint Process: A Phenomenological Study, Amy Elizabeth Kilpatrick

Dissertations

The right of parents of students with disabilities to dispute decisions or actions by the school district is one of the tenets of the Individuals with Disabilities Education Act (IDEA). Of the three formal dispute resolution mechanisms under the IDEA, written state complaints (WSC) are the most commonly completed, from start to finish, yet the least researched. Research of the other dispute resolution processes, due process hearings and mediation, suggests that the processes are costly, stressful for all parties, and cause damage to the FPPs. To address this gap in research, this qualitative study investigated the WSC process from the …

Quantifying The Combined Effect Of Abiotic Factors On The Decomposition Of Organic Matter In Semiarid Grassland Soils, Elnazsadat Hosseiniaghdam

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Grassland ecosystems play a critical role in the global carbon cycle, and their cumulative carbon dioxide (CO₂) emissions can be affected by animal grazing where litter (i.e., dead plant material) is trampled into the soil. However, the subsequent effects of trampling on litter decomposition are not well understood. Meanwhile, abiotic factors, especially temperature and soil moisture, are known to strongly affect litter decomposition. Due to the very small number of published studies that have considered litter placement, either litter on top of soil or litter mixed with soil as a factor in litter decomposition under different temperature and …

Género Y Sexualidad En Seis Novelas Del Siglo Xxi, Sandra Chang Raak

Dissertations

From its inception Latin American literature has used gender and sexuality as rhetorical devices to approach the topic of cultural identity. For instance, Hernán Cortés in his Cartas de Relación embodies a type of masculinity that overdetermined the lives of the Amerindian people. Centuries later, the modernismo movement headed by Rubén Darío reacted to a Latin American societal shift towards the prevalence of a materialistic culture brought about by the advent of industrial civilization. During the 1960s Latin American literature experienced a rapid blooming that has come to be known as El Boom. Both landmarks, modernism and El Boom …

Photocatalytic And Photochemical Decomposition Of Various Per- And Polyfluoroalkyl Substances (Pfas) In Water, Nusrat Chowdhury

Civil Engineering Dissertations - Archive

Per- and polyfluoroalkyl substances (PFAS) are anthropogenic compounds comprised of a perfluoroalkyl backbone and a terminal functional group. Their detrimental health effects of in humans, like other halogenated chemicals, have been well documented and thus the frequent occurrence of PFAS in the water environment is a recent global concern. After US Environmental Protection Agency (EPA) released a drinking water health advisory for the two most detected long chain PFAS (such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS)), industrial production and application of short chain PFAS continues to rise. Feasible and sensible treatment strategies are in dire need for environmental …

Application Of In Situ And Ex Situ Characterization Of Atomic Layer Deposition Processes For Gallium Phosphide And Sodium Fluoride, Sara Rose Kuraitis

Boise State University Theses and Dissertations

Atomic layer deposition (ALD) is a vapor deposition technique for synthesizing thin films with nanometer thickness control. ALD films are deposited on a substrate surface in a cyclic layer-by-layer fashion utilizing alternating doses of highly reactive chemical precursors. Precursors are selected to undergo self-limiting chemical reactions with the surface, and desired film thickness is achieved by varying the number of ALD cycles accordingly. Optimization of ALD process parameters and precursor chemistry enables conformal coating of arbitrary substrate geometries, including high aspect ratio features such as trenches. In the decades since its introduction, ALD has been used for applications across many …

Queer Lives In Idaho And The Surrounding Region: Impacts Of Anti-Discrimination Laws, High School Environment, And The Covid-19 Pandemic On Mental Health, Ollie Shannon

Boise State University Theses and Dissertations

The experiences of Queer people in the Intermountain-West are under- documented by the scientific community. Suicide is the 10th leading cause of death in the United States. It was responsible for more than 47,500 deaths in 2019. Members of the Queer community have higher rates of suicidal ideation and attempts than the general population. Theoretically, we may predict that people experience negative mental health outcomes under situations of reduced social contact and support or during periods of exclusion by conspecifics. My research explores mental health in the Queer community utilizing data collected in an online survey during the COVID-19 pandemic. …

Autophagy Regulation By Lipid Factors With Implications For Parkinson's Disease, Alejandro Soto-Avellaneda

Boise State University Theses and Dissertations

Parkinson’s disease is the second most common neurodegenerative disorder. It is characterized by the death of dopaminergic neurons in the substantia nigra and a series of debilitating motor symptoms. Macroautophagy (hereafter referred to as autophagy) is a cellular process by which cells degrade proteins, lipids, organelles or dysfunctional components. Autophagy is thought to play an important role in Parkinson’s disease, because it is the only cellular process known to remove large protein aggregates, such as those seen in Parkinson’s disease pathology. Historically, a large body of work has focused on reporting on protein effectors of autophagy, and regulation of autophagy …

Ai As A Boost For Startups Companies: Evidence From Italy, Irene Di Bernardo, Marco Tregua, Greco Fabio, Ruggiero Andrea

University of South Florida (USF) M3 Publishing

Innovative startups are growing everywhere; clearly, digital transformation is imperative for all businesses to compete, or better survive. Institutions prompt companies and businesses to adopt digital transformation tools, providing funds too, especially to startups (MISE, 2019).In particular, this study analyzes Artificial Intelligence, understanding its implications, ties and features in startups. No commonly agreed definitions are given about AI and startups, thus the tie between them should be deepened. One of the most cited definitions considers startup as a temporary organization looking for scalable business models (Blank, 2013). In literature little attention has been paid to the connection between startup and …

Development Of A Hybrid Hydrogel Drug Delivery System For Treatment Of Ischemic Injury, Andrew Demaria

All Dissertations

In the United States, ischemia resulting from cardiovascular disease and acute trauma affects nearly 50% of all adults. Therapeutic angiogenesis aims to stimulate the formation of new microvasculature that alleviates hypoxia, reduces tissue morbidity, and improves wound healing. The current primary therapeutic approach is vascular endothelial growth factor (VEGF) injection therapy but is hindered by several challenges. Consequently, bioactive small molecules are being used to target hypoxia-inducible factor-1α (HIF-1α), the master regulator of oxygen-sensing pathways that is responsible for activating angiogenesis in response to tissue hypoxia. However, successful clinical translation of small molecules for therapeutic angiogenesis still faces several challenges …
