Therefore, the focus is on palatability of vegetation to livestock, and the effects of livestock management and external factors on the condition of the vegetation and soils.

The first section provides an overview and map, introduces concepts and terms important to understanding arid shrubland management in general, these guides in particular, and includes an economic analysis of the …

Effectively Preparing Art Students For Artistic Careers: A Study On Art Schools’ Relation To The Art Market And Their Approaches To Preparing Students For Career Navigation, William Stewart

MA Theses

Master’s of Fine Arts (MFAs) in visual arts have seen significant growth in their tuition and number of degrees conferred over recent decades. As the popularity of the MFA expanded during this period, the breadth, power, and influence of the global art market has as well. The commercial art market’s structure and competitiveness creates serious barriers to entry for art students attempting to navigate its complexities and strengthen their creative careers. Despite the
/="/">market’s growth, many art schools’ attitudes and curricular offerings have not adjusted to its expanded importance. According to a range of statistical studies and anecdotal accounts, …

Abnormal Thalamic Functional Connectivity Correlates With Cardiorespiratory Fitness And Physical Activity In Progressive Multiple Sclerosis, Francesco Romanò, Robert W. Motl, Paola Valsasina, Maria Pia Amato, Giampaolo Brichetto, Nicolò Bruschi, Jeremy Chataway, Nancy D. Chiaravalloti, Gary Cutter, Ulrik Dalgas, John Deluca, Rachel Farrell, Peter Feys, Jennifer Freeman, Matilde Inglese, Cecilia Meza, Amber Salter, Brian M. Sandroff, Anthony Feinstein, Maria A. Rocca, Massimo Filippi

School of Health Professions

BackgroundAltered thalamic volumes and resting state (RS) functional connectivity (FC) might be associated with physical activity (PA) and cardiorespiratory fitness (CRF) in people with progressive multiple sclerosis (PMS).ObjectivesTo assess thalamic structural and functional alterations and investigate their correlations with PA/CRF levels in people with PMS.MethodsSeven-day accelerometry and cardiopulmonary exercise testing were used to assess PA/CRF levels in 91 persons with PMS. They underwent 3.0 T structural and RS fMRI acquisition with 37 age/sex-matched healthy controls (HC). Between-group comparisons of MRI measures and their correlations with PA/CRF variables were assessed.ResultsPMS people had lower volumes compared to HC (all p < 0.001). At corrected threshold, PMS showed decreased intra- and inter-thalamic RS FC, and increased RS FC between the thalamus and the hippocampus, bilaterally. At uncorrected threshold, decreased thalamic RS FC with caudate nucleus, cerebellum and anterior cingulate cortex (ACC), as well as increased thalamic RS FC with occipital regions, were also detected. Lower CRF, measured as peak oxygen consumption (VO2peak), correlated with lower white matter volume (r = 0.31, p = 0.03). Moreover, lower levels of light PA correlated with increased thalamic RS FC with the right hippocampus (r = − 0.3, p = 0.05).DiscussionPeople with PMS showed widespread brain atrophy, as well as pronounced intra-thalamic and thalamo-hippocampal RS FC abnormalities. White matter atrophy correlated with CRF, while increased thalamo-hippocampal RS FC was associated to worse PA levels. Thalamic RS FC might be used to monitor physical impairment and efficacy of rehabilitative and disease-modifying treatments in future studies.

Ccl2 Suppression In Lewis Lung Carcinoma Model Enhances Host Survival And Immune Response In The Tumor Microenvironment, Nivedita Biswas

Theses and Dissertations

CCL2, a chemokine also referred to as monocyte chemoattractant protein 1 (MCP-1) and small inducible cytokine A, is chemotactic for monocytes. CCL2-induced recruitment of CCR2+Ly6C(hi) monocytes increases vascular permeability CCR2+ endothelium aiding the escape and migration of tumor cells. CCL2 is produced by cancers of varied immunogenicity and augments tumor proliferation and metastasis. Elevated CCL2 expression by tumor cells is linked to poor prognosis.We have previously shown that two bacterially derived superantigens, Staphylococcal enterotoxin G and I (SEG/SEI) stimulate large numbers of T cells in an antigen-independent fashion and promote enhanced survival in the poorly immunogenic B16-F10 melanoma model. Conversely, …

Dyslexia And The Need For General Education Teacher Training, Sheeresa S. Begay

Theses and Dissertations

General education teachers are expected to provide instruction to and promote learning in all students within a general education classroom per state and federal mandates. These mandates ensure students with disabilities like dyslexia are given access to a general education classroom, curriculum, and materials, and provided with support through an Individualized Education Program (IEP) or 504 Plan. However, general education teacher training and professional development programs have often been ineffectual in preparing general education teachers for delivering instruction to and promoting learning in individuals with dyslexia. As a result, many general education teachers are unprepared for supporting students with dyslexia …

Nickel-Titanium (NiTi) alloy, also known as Nitinol, has unique properties such as shape memory and superelasticity, which make it a valuable material for various applications in the medical and aerospace industries. However, due to its high toughness, strength, and ductility, NiTi is difficult to form and machine, leading to severe tool wear and high cutting energy. Conventional manufacturing processes have limitations in producing complex or porous designs, restricting NiTi's potential applications. Additive manufacturing techniques have been explored as a way …

Soil Bacteria Composition In Conservation Reserve Program Grasslands Of The Great Plains, Lydia M. Kantonen

Theses and Dissertations

The Conservation Reserve Program (CRP) is a grassland restoration program that allows landowners to remove degraded land from crop production, seed it with a perennial seed mixture, and leave it fallow for the remainder of the contract, which usually ranges from 10-15 years. While some ecosystem functions quickly improve upon CRP enrollment, soil organic carbon is slow to return to pre-agricultural levels. One explanation is that particulate organic matter left by litter takes several years to degrade even with a full bacteria community. Alternatively, it is possible that different chemical components of organic matter require different bacteria communities for full …

Natural Fractals And Facial Emotion Recognition, Nathaniel Joseph Pagel

Theses and Dissertations

The psychological benefits that come from visually processing natural imagery have been widely studied. The components of natural imagery that provoke positive responses are not fully understood. This study uses a mixed design approach to identify if the acute exposure to statistical fractal imagery, of both a high-range or mid-range complexity, affects cognitive workload, physiological arousal, and gaze patterns in the recognition and identification of emotions through facial expressions. Participants were undergraduate students fulfilling a partial course requirement (N = 87). Eye-tracking metrics were used to compare exposure to fractal complexities. Participants were randomly assigned to either be exposed to …

Childhood Adversity And The Millon Clinical Multiaxial Inventory, Fourth Edition (Mcmi-Iv), Jenna Marie Wolff

Theses and Dissertations

The Millon Clinical Multiaxial Inventory, 4th edition (MCMI-IV; Millon et al., 2015) is a reliable and valid personality assessment based on Theodore Millon’s biosocial learning theory of personality. Millon’s theory evolved to include 15 personality constructs that vary in adaptive and maladaptive response patterns. In his most recent book (Millon, 2011), he presented hypotheses about biological and environmental factors that contribute to development of each personality construct. Many of these hypotheses specify particular adversities in childhood that differentially contribute to each construct. This study is the first to evaluate Millon’s hypotheses about how childhood adversities may contribute to development of …

The Predictiveness Of Gendered Racism On The Well-Being Of Women Of Color, Mallika Chakrabarti

Theses and Dissertations

Research suggests a reduced sense of well-being in women of color who have been experiencing discrimination based on gender or race. Surprisingly, the intersectional discrimination of both gender and race, termed as Gendered Racism, on women of color has received much less attention than the individual variables. The present study seeks to fill a void in literature by offering to examine some effects of gendered racism on aspects of well-being in this population. This study examines the predictiveness of intersectional discrimination based on race and gender – called Gendered Racism - on the well-being of women of color. Well-being was …

The Interplay Between Parp-1 And Histone Modifications In Transcriptional Regulation During Development And Heat Shock Response, Gbolahan Gbenga Bamgbose

Theses and Dissertations

Poly(ADP-ribose) polymerase 1 (PARP-1), a multifunctional nuclear enzyme, plays a crucial role in transcriptional regulation through its three functional domains: the N-terminal DNA-binding domain (DBD), the automodification domain (AD), and the C-terminal domain, which includes the WGR and the catalytic domains. Despite its importance, the mechanisms directing PARP-1 to chromatin remain unclear and PARP-1’s role in development is still poorly understood. In chapter II, we interrogated the role of PARP-1 domains in PARP-1 to chromatin. We used ChIP-seq of YFP-tagged deletional isoforms of PARP-1 and a construct that lacks only the first zinc finger domain (ΔZnI). Interestingly, our findings suggest …

Acaricidal Activity Of The Orally Administered Isoxazoline Drugs (Lotilaner, Fluralaner, And Afoxolaner) In White-Footed Mice Against Larval Ticks, Emily Marie Gisi

Theses and Dissertations

Lyme disease, caused by Borrelia burgdorferi, is currently the most prevalent vector borne disease in North America. With the CDC estimating almost 500,000 new cases every year, methods are needed to control the vector, the black legged tick (Ixodes scapularis). Like other tick-borne diseases, Lyme disease is zoonotic and involves tick parasitism on rodent reservoirs in the wild. The main reservoir host of Lyme disease is the white-footed mouse (Peromyscus leucopus). This study aims to explore the effectiveness of a reservoir targeted control approach by the treatment of white-footed mice with oral isoxazoline class drugs. …

Understanding Nanog's Role During Cell Differentiation, Oluwatobiloba Samuel Aminu

Theses and Dissertations

Pluripotency is characterized by the capacity to self-renew and differentiate into all cell types. This state relies on both extrinsic factors, such as leukemia inhibitory factor and bone morphogenetic protein, and intrinsic factors, including pluripotent transcription factors.While the role of pluripotent transcription factors in stem cell maintenance is well understood, their functions beyond pluripotency remain unclear. In this study, we focused on NANOG, a core member of the pluripotency network, and investigated its roles in two different models of differentiation: the transition from the naive to the primed pluripotent state and neuroectodermal differentiation. Our findings demonstrate that NANOG plays a …

A Deep Review Of Sustainable Approaches For Hydrogen Production For Energy Generation, Patrick Bernard Ferron

Theses and Dissertations

Fossil fuel energy sources such as coal, oil, and natural gas produce greenhouse gases upon combustion. Over time the greenhouse gases trap heat in the atmosphere and cause global temperatures to continually increase. This continued rise in global temperatures has led to severe climate conditions that have resulted in increasing environmental, financial, social, and medical issues. To mitigate the rise in global temperatures, and the negative effects associated with it, the carbon intensity of our energy sources must be substantially reduced or eliminated where possible. In addition, alternate sources of carbon-free energy sources must be pursued and implemented. Hydrogen is …

Computational Framework For Neuro-Optics Simulation And Deep Learning Denoising, Cecilia Ling

Theses and Dissertations

The application of machine learning techniques in microscopic image restoration has shown superior performance. However, the development of such techniques has been hindered by the demand for large datasets and the lack of ground truth. To address these challenges, this study introduces a computer simulation model that accurately captures the neural anatomic volume, fluorescence light transportation within the tissue volume, and the photon collection process of microscopic imaging sensors. The primary goal of this simulation is to generate realistic image data for training and validating machine learning models. One notable aspect of this study is the incorporation of a machine …

Intergenerational Continuity Of Sexual Violence Victimization: A Socio-Ecological Examination Of Risk, Angela Hunter Minnich

Theses and Dissertations

The present study examined intergenerational continuity of sexual violence victimization across the lifespan within mother-daughter dyads. Because increased risk for sexual violence in daughters is not the fault of the mother, this study examined risk factors across socio-ecological levels (i.e., individual, familial, and community risk factors) and the interplay across risk levels. Undergraduate and community dwelling mother-daughter dyads (N=202) completed self-report measures of Childhood Sexual Abuse (CSA), adolescent/adult sexual violence victimization (ASV), demographics, psychopathology, parenting, abuse and abuser characteristics, intimate partner violence (IPV), rape culture, and sexual education characteristics. Multiple mediation, moderation, and DYADIC analyses were implemented to test study …

Teaching Professionalism To Undergraduate Medical Laboratory Science Students Using Virtually Simulated Case Studies, Samantha Peterson

Theses and Dissertations

Professionalism is a required curricular component in accredited medical laboratory science (MLS) programs in the United States and is a critical element for career success and optimal patient care. A standardized definition of professionalism in MLS, however, has yet to be established. This poses a challenge to MLS programs when pertaining to teaching professionalism to MLS students. To explore a novel method for teaching professionalism in MLS, interactive and virtually simulated case studies were designed and built to cover three professional behaviors required of MLS professionals. Before and after case study completion, students (n= 49) responded to a survey designed …

Application Of Artificial Intelligence And Multi-Omics To Understand The Effect Of Heavy Metals Exposure On Human Health, Sonalika Singhal

Theses and Dissertations

IARC classified arsenic (iAs) as “carcinogenic to humans”, but despite the health consequences, there is no molecular signature available yet to predict when exposure may lead to the disease development. In this study, a three-step analysis was employed: (1) the gene expression profiles obtained from diverse arsenic-exposed populations were utilized to identify differentially expressed genes associated with arsenic exposure in human subjects, (2) the gene expression profiles induced by arsenic exposure in different myeloma cancer cell lines were used to define common genes and pathways altered by arsenic exposure,(3) the genetic profiles of human bladder cancer studies were used to …

Plant Composition And Turnover In Great Plains Conservation Reserve Program Grasslands, Lydia M. Westberg

Theses and Dissertations

The Conservation Reserve Program supports grassland reconstruction practices that vary in the number (richness) and identity of species added to enrolled sites. Although the program is administered at the federal level, the methods and species pools used to reconstruct these grasslands have changed over time and vary across the United States. Additionally, while the goal is to augment site species pools with desired species, there is some question as to what extent the prescribed practices result in a diverse species pool over the long term given the immense non-native propagule pressure that can exist on these sites. Unfortunately, no large-scale …

A Molecular Phylogeny Of Ctenuchina Kirby, 1837 (Lepidoptera: Erebidae: Arctiinae: Arctiini: Ctenuchina), Sydney Winterton

Theses and Dissertations

Ctenuchina are a subtribe of tiger moths in the subfamily Arctiinae and are known for their aposematism and mimicry of noxious insects. Their overall appearance signals predators of their unpalatability due to larval sequestration of plant secondary chemicals. The taxonomic history of Ctenuchina is complicated because of convergent phenotypes within the lineage and with other tiger moth groups such as the Euchromiina. Independent evolutionary events that converge on mimetic phenotypes obscure evolutionary relationships and render classifications based on morphology to be suspect. Although morphological phylogenies have since been used less often in favor of quantifiable, molecular-based phylogenies, these studies provide …

Integrating Technology Into Wildlife Surveys, Sally E. Yannuzzi

Theses and Dissertations

Technology is rapidly improving and being incorporated into field biology, with survey methods such as machine learning and uncrewed aircraft systems (UAS) headlining efforts. UAS paired with machine learning algorithms have been used to detect caribou, nesting waterfowl and seabirds, marine mammals, white-tailed deer, and more in over 19 studies within the last decade alone. Simultaneously, UAS and machine learning have also been implemented for infrastructure monitoring at wind energy facilities as wind energy construction and use has skyrocketed globally. As part of both pre-construction and regulatory compliance of newly constructed wind energy facilities, monitoring of impacts to wildlife is …

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 …

Effects Of Peri-Urbanization On Coastal Sage Scrub Ant Species In Baja California, Alejandro E. Mieles, Margaret A. Voss, Estelí Jiménez-Soto

School of Geosciences Faculty and Staff Publications

Increasing urbanization on the Baja California Peninsula threatens ant diversity. Reductions in ant species diminish ecosystem services provided to semiarid coastal scrub areas. Peri-urban areas in particular are at high risk of reductions in ant biodiversity due to development. To document and evaluate ant species diversity and richness in a rapidly developing area, nine sites were sampled within areas of coastal sage scrub (CSS) encircling the urban periphery of Ensenada, Baja California. Forty species and 17 genera of ants were collected, only one of which was non-native. Although the sampled area represents less than 1% of the peninsula and 3% …

Naturally Occurring Vegetation Connectivity Facilitates Ant-Mediated Coffee Berry Borer Removal, Sanya Cowal, Jonathan R. Morris, Estelí Jiménez-Soto, Stacy M. Philpott

School of Geosciences Faculty and Staff Publications

Vegetation connectivity is an essential aspect of the habitat complexity that impacts species interactions at local scales. However, agricultural intensification reduces connectivity in agroforestry systems, including coffee agroecosystems, which may hinder the movement of natural enemies and reduce the ecosystem services that they provide. Ants play an important role in regulating the coffee berry borer (CBB), which is the most damaging coffee pest. For arboreal ant communities, the connections between trees are important structures that facilitate ant mobility, resource recruitment, foraging success, and pest control ability. To better understand how connectivity impacts arboreal ants in coffee agroecosystems, we conducted an …

Room-Temperature Crystallography Reveals Altered Binding Of Small-Molecule Fragments To Ptp1b, Tamar Skaist Mehlman, Justin T. Biel, Syeda Maryam Azeem, Elliot R. Nelson, Sakib Hossain, Louise Dunnett, Neil G. Paterson, Alice Douangamath, Romain Talon, Danny Axford, Helen Orins, Frank Von Delft, Daniel A. Keedy

Advanced Science Research Center

Much of our current understanding of how small-molecule ligands interact with proteins stems from X-ray crystal structures determined at cryogenic (cryo) temperature. For proteins alone, room-temperature (RT) crystallography can reveal previously hidden, biologically relevant alternate conformations. However, less is understood about how RT crystallography may impact the conformational landscapes of protein-ligand complexes. Previously, we showed that small-molecule fragments cluster in putative allosteric sites using a cryo crystallographic screen of the therapeutic target PTP1B (Keedy et al., 2018). Here, we have performed two RT crystallographic screens of PTP1B using many of the same fragments, representing the largest RT crystallographic screens of …

Expandable Intravertebral Implants In Post-Traumatic Vertebral Necrosis - New Classification Suggestion., Diogo Lino Moura, Josué Pereira Gabriel

Trauma and Acute Care Articles

The progressive evolution of post-traumatic vertebral necrosis and consequent loss of structural integrity of the vertebral body along with neurological risk, makes it one of the most feared and unpredictable pathologies in spine traumatology. Several studies have addressed the role of vertebroplasty, kyphoplasty, and corpectomy in its treatment; however, it remains a controversial concept without a defined therapeutic algorithm. The recent emergence of expandable intravertebral implants, which allow, by a percutaneous transpedicular application, the capacity for intrasomatic filling and maintenance of the height of the vertebral body, makes them a viable option, not only in the treatment of acute vertebral …
