Infant Exposure To Potentially Traumatic Events In The Neonatal Intensive Care Unit, Amy L. D'Agata

Doctoral Dissertations

Infants who begin life in the medicalized environment of the neonatal intensive care unit (NICU) do so under adverse conditions. The NICU experience exposes infants to experiences that are different from well newborns. The impact these cumulative adverse conditions have on long-term neurodevelopment has yet to be fully elucidated, however the literature reveals a broad scope of later life challenges for former NICU infants. This dissertation focuses on several novel inquiries that may shed light on individual vulnerabilities. First, a framework of infant trauma is proposed to support improved understanding of the infant experience. Context is provided for the history …

Exploration Of The Range Overlap Between Cynomys Leucurus And Cynomys Ludovicianus, Kenneth D. Choi

Honors Theses

The ranges of two species of prairie dogs, Cynomys leucurus and Cynomys ludovicianus, overlap in a narrow area in the western Great Plains in Wyoming. We used GIS software to map their distributions and infer land cover preferences within and on either side of the zone of overlap. In general, both species used habitats in proportion to their availability and did not display strong selection of their expected vegetation types (based on the literature). However, both species of prairie dogs were overrepresented in areas of human settlements and crops, which may indicate that these species prefer human-modified habitats, or perhaps …

L3 Auditory Interneuron Responses To Dual-Frequency Calling Songs In Female Crickets (Acheta Domesticus), Jeong Bin Lee

Honors Theses

Female crickets exhibit positive phonotaxis in response to calling songs with specific carrier frequencies (4-5 kHz), syllable periods (SP; 50-70ms), and other parameters. Among a number of ascending prothoracic auditory neurons identified, only L3 has been proposed to be involved in SP selective phonotaxis. L3 responds with selective decrement to 5 kHz stimulus with attractive SPs. Furthermore, L3 is highly tuned to 16 kHz auditory stimulus, which has been correlated with aversive phonotactic behaviors. L3’s cellular responses to simultaneous 16 kHz and 5 kHz stimuli were examined through extracellular recording, thereby further establishing the connection between L3’s selective decrement and …

Potential Cellular Mechanisms Of Estrogen's Effects On Maintaining Sperm Production In Aging Rats, Matthew Pate

Honors Theses

Testosterone production by Leydig cells declines during aging in both men and rodent models. Previous results from our lab demonstrated that daily sperm production also declines in aging rats and alterations in the estrogen environment of the testis contribute to this decline. Importantly, estrogen treatment during aging was able to attenuate the age-associated decline in sperm production. However, the cellular and molecular mechanisms by which estrogen maintains sperm production remain unclear. These experiments were designed to further investigate the effects of estrogen on sperm production in an attempt to further define the cellular mechanisms regulated by estrogen within the testis. …

The key developments, the key players and an accurate state of the industry are hereby presented through the eyes of the ISPCS from this past eleventh symposium that spanned two days and was held …

Elevation Promotes Long-Term Survival Of Pinus Elliottii Var. Densa, A Foundation Species Of The Endangered Pine Rockland Ecosystem In The Florida Keys, Grant L. Harley, Justin T. Maxwell, George T. Raber

Faculty Publications

The pine rockland community in southern Florida, which supports numerous state- and federally listed flora and fauna species, is considered endangered. Without its foundation species, Pinus elliottii var. densa, habitat and species diversity are lost to tropical hardwood hammock. Here, we investigate the landscape factors that contribute to the long-term persistence of pine rocklands on the 2 islands that contain the largest remaining habitat in the Florida Keys: Big Pine Key and No Name Key. Plot-level biophysical data and island-scale remotely sensed vegetation data were collected from pine rockland savannas and examined with multi-dimensional analysis. On both islands, vegetation …

Precognition: Bodies In Network, Kate Hoyt

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

Precognition” is an installation that seeks to explore the liminal space between actor and environment, human and technology, and self and Other through the performativity of flow. Deleuze and Guattari use the term “flow” to describe a deliberately imprecise way of knowing or understanding meaning beyond, across, and within the existing category of the form (trans. 1987). Within the materialist ontology of poststructuralism, it is not the form that matters so much as the substance - energies and affects entangle us with our surroundings, affording a radical questioning of the rational, contained self that remains so central to the Western, …

Disrupting Privileged And Oppressed Spaces: Reflecting Ethically On My Arabness Through Feminist Autoethnography, Haneen Ghabra

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

This essay urges for the need to explore one’s privileges and oppressions through Feminist Arabness. Through intersectionality, the author brings forth various experiences as a woman of color. By exploring privileges and oppressions, the goal is to bring contestations of domination into conversation with neoliberalism, reflexivity and ethical communication. Thus, this study is a call to highlight the need for an integrated approach that combines theory, and Autoethnography in order to reflect a richer intersectional analysis that combines both privileges and oppressions as identities. It is also a call towards an intersectional feminist ethic that can in turn identify the …

Demystifying Variance In Performance: Toward A Multilevel Longitudinal Perspective Of Strategic Management, Guangrui Guo

Open Access Dissertations

Drawing upon complexity theory, this dissertation contributes both to inquiry on relative importance of business–unit, corporation, industry, and year effects on firm performance and to development of a multilevel longitudinal perspective of strategy. Empirically, this dissertation generates important new insights about variation in performance. This dissertation is the first to (1) capture substantial stable corporation–industry interaction effects that were confounded with stable effects of business unit, corporation, and industry in results of previous studies, (2) demonstrate that stable effects of corporation, industry, corporation–industry interaction, taken together, are of similar relative magnitude to that of stable BU effects, (3) reveal that …

Exploring Black/White Biracial Female Therapists’ Perceptions And Meaning-Making In The Context Of Providing Therapy, Anna Wheatley Scarbriel

Open Access Dissertations

Individuals born to parents from two or more different racial groups are one of the fastest growing population groups in the United States, with Black/White biracials making up the largest proportion therein. This diversification has permeated the field of psychology and counseling, and people of mixed race will increasingly be clients, colleagues, supervisors, and supervisees. It is imperative that the field of counseling and psychology turn attention not only to serving/treating mixed race clients, but also to providing training and supervision to mixed race professionals. In particular, much work remains to better understand the significance and impact of a mixed …

Gelatinous Zooplankton In Marine Communities And Ecosystems: Fine-Scale Horizontal And Vertical Distribution, Trophic Drivers, And Contribution To Global Carbon Cycling, Jessica Yuchao Luo

Open Access Dissertations

The gelatinous zooplankton (GZ), comprised of cnidarians, ctenophores, and pelagic tunicates, are an abundant, diverse group of organisms that often exhibit boom-and-bust population dynamics. Most of the work on GZ has been focused on the large scyphozoans, while the smaller members of this group (hydrozoans, ctenophores, and pelagic tunicates) are relatively understudied due to their size, fragility, and transparency. Furthermore, spatially and temporally variable GZ populations can have important ecosystem impacts, e.g. to the biological pump via sinking carcasses and fecal pellet production. This dissertation investigates gelatinous zooplankton and their role in marine communities and ecosystems, with respect to 1) …

Oxidative Stress In Avian Embyros, Toshi Tsunekage

Dissertations

Oxidative stress has been implicated in mediating trade-offs in the evolution of life histories. Oxidative stress results from an imbalance in the production of free radicals and an organism’s antioxidant defenses. Higher metabolic rates associated with more rapid growth and shorter development periods may increase oxidative stress and accumulated cellular damage in embryonic tissues. In my dissertation I explored oxidative stress and antioxidant defenses in avian embryos. I measured levels of oxidative stress in tissues of different stage embryos of Japanese quail (Coturnix japonica), and tested if patterns of lipid peroxidation could be explained by changes in the developing embryo’s …

Geographic Variation, Null Hypotheses, And Subspecies Limits In The California Gnatcatcher: A Response To Mccormack And Maley, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda

School of Natural Resources: Faculty Publications

We interpreted the results of nuclear DNA sequencing to be inconsistent with the recognition of California Gnatcatcher (Polioptila californica) subspecies. McCormack and Maley (2015) suggested that our data did support 2 taxa, one of which was P. c. californica, listed as Threatened under the Endangered Species Act (ESA). We summarize here how 2 sets of researchers with access to the same data reached different conclusions by including different analyses. We included the southern subspecies’ boundary from the taxonomy of Atwood (1991), the taxonomic basis for the ESA listing, which resulted in an Analysis of Molecular Variance that …

Multi-Modal Outcomes From Interpersonal Need (Un)Fulfillment: The Emotional, Cognitive And Behavioral Derivatives Of Consecutive Social Contingencies, Kyle Steven Hull

Doctoral Dissertations

The current study assessed the relationship between the core dimensions of interpersonal communication and relationships, power and intimacy, on the activation of individualistic-prosocial affect systems and subsequent interpersonal outcomes. Despite extensive research examining each dimension, mixed findings are prevalent and few have investigated their potential interaction. This study addressed these issues based on current trends in interdisciplinary research. Specifically, manipulated social triumph-defeat was followed by social inclusion-exclusion to examine their combined effect on interpersonal outcomes. Results indicate that the power and intimacy manipulations were successful, however, the relationship between them was not interactive. The current findings contradict the logical expansion …

The First Bromeligenous Species Of Dendropsophus (Anura: Hylidae) From Brazil's Atlantic Forest, Rodrigo Barbosa Ferreira, Julián Faivovich, Karen H. Beard, José P. Pombal Jr

Wildland Resources Faculty Publications

We describe a new treefrog species of Dendropsophus collected on rocky outcrops in the Brazilian Atlantic Forest. Ecologically, the new species can be distinguished from all known congeners by having a larval phase associated with rainwater accumulated in bromeliad phytotelms instead of temporary or lentic water bodies. Phylogenetic analysis based on molecular data confirms that the new species is a member of Dendropsophus; our analysis does not assign it to any recognized species group in the genus. Morphologically, based on comparison with the 96 known congeners, the new species is diagnosed by its small size, framed dorsal color pattern, and …

Genetic Modification Of Human Mesenchymal Stem Cells Helps To Reduce Adiposity And Improve Glucose Tolerance In An Obese Diabetic Mouse Model., Sabyasachi Sen, Cleyton C Domingues, Carol Rouphael, Cyril Chou, Chul Kim, Nagendra Yadava

Medicine Faculty Publications

INTRODUCTION: Human mesenchymal stem cells (MSCs) are multipotent cells that can differentiate into fat, muscle, bone and cartilage cells. Exposure of subcutaneous abdominal adipose tissue derived AD-MSCs to high glucose (HG) leads to superoxide accumulation and up-regulation of inflammatory molecules. Our aim was to inquire how HG exposure affects MSCs differentiation and whether the mechanism is reversible.

METHODS: We exposed human adipose tissue derived MSCs to HG (25 mM) and compared it to normal glucose (NG, 5.5 mM) exposed cells at 7, 10 and 14 days. We examined mitochondrial superoxide accumulation (Mitosox-Red), cellular oxygen consumption rate (OCR, Seahorse) and gene …

Substituent Effects On The Binding Of Halides By Neutral And Dicationic Bis-Triazolium Receptors, Binod Nepal, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The effects of substituent and overall charge upon the binding of a halide anion by a bis-triazolium receptor are studied by M06-2X DFT calculations, with the aug-cc-pVDZ basis set. Comparison is also made between a receptor that engages in H-bonds, with a halogen-bonding species. Fluoride is clearly most strongly bound, followed by Cl-, Br-, and I- in that order. The dicationic receptor engages in stronger complexes, but not by a very wide margin compared to its neutral counterpart. The binding is enhanced as the substituent on the two triazolium rings becomes progressively more electron-withdrawing. Halogen-substituted receptors, whether neutral or cationic, …

Connectivity Of Coastal And Oceanic Ecosystems: Pelagic Habitat Use By Juvenile Reef Fishes In The Gulf Of Mexico, Katie Bowen

HCNSO Student Theses and Dissertations

The assemblage structure, abundance, biomass, and vertical distribution of juvenile reef fishes in the offshore pelagic habitat of the northern Gulf of Mexico are described as part of the NOAA-supported Offshore Nekton Sampling and Analysis Program. The results presented here are from a 3-month, continuous sampling series in 2011 in which discrete depth strata from 0 to 1500 m were sampled using a 10-m² MOCNESS midwater trawl. This is the first study to examine pelagic juvenile reef fish distributions across the entire oceanic northern Gulf of Mexico seaward of the continental shelf break after the Deepwater Horizon Oil Spill. …

Perceptions Of Thermal Comfort: Landscape Design Attributes Based On The Shops At La Cantera In San Antonio, Texas, Krishan Patel

Landscape Architecture Masters & Design Theses - Archive

The focus of this thesis was to understand people’s perceptions of thermal comfort. Understanding design attributes that affect thermal comfort in outdoor spaces is necessary, as it will have a major influence on the design of urban outdoor spaces (Nikolopoulou and Steemers, 2003). The research will have great implications on the field of landscape architecture, architecture, urban design, and planning, Indoor malls are no longer being built. The trend is moving towards lifestyle centers. Lifestyle centers offer an experience that can’t be replicated by indoor malls. Lifestyle centers are open to the sky and as a result, they are exposed …

Linker Histone H1 And H3k56 Acetylation Are Antagonistic Regulators Of Nucleosome Dynamics, Morgan Bernier, Yi Luo, Kingsley C. Nwokelo, Michelle Goodwin, Sarah J. Dreher, Pei Zhang, Mark R. Parthun, Yvonne N. Fondufe-Mittendorf, Jennifer J. Ottesen, Michael G. Poirier

Molecular and Cellular Biochemistry Faculty Publications

H1 linker histones are highly abundant proteins that compact nucleosomes and chromatin to regulate DNA accessibility and transcription. However, the mechanisms that target H1 regulation to specific regions of eukaryotic genomes are unknown. Here we report fluorescence measurements of human H1 regulation of nucleosome dynamics and transcription factor (TF) binding within nucleosomes. H1 does not block TF binding, instead it suppresses nucleosome unwrapping to reduce DNA accessibility within H1-bound nucleosomes. We then investigated H1 regulation by H3K56 and H3K122 acetylation, two transcriptional activating histone post translational modifications (PTMs). Only H3K56 acetylation, which increases nucleosome unwrapping, abolishes H1.0 reduction of TF …

Igf-I Induces Upregulation Of Ddr1 Collagen Receptor In Breast Cancer Cells By Suppressing Mir-199a-5p Through The Pi3k/Akt Pathway., Roberta Matà, Chiara Palladino, Maria Luisa Nicolosi, Anna Rita Lo Presti, Roberta Malaguarnera, Marco Ragusa, Daniela Sciortino, Andrea Morrione, Marcello Maggiolini, Veronica Vella, Antonino Belfiore

Kimmel Cancer Center Faculty Papers

Discoidin Domain Receptor 1 (DDR1) is a collagen receptor tyrosine-kinase that contributes to epithelial-to-mesenchymal transition and enhances cancer progression. Our previous data indicate that, in breast cancer cells, DDR1 interacts with IGF-1R and positively modulates IGF-1R expression and biological responses, suggesting that the DDR1-IGF-IR cross-talk may play an important role in cancer.In this study, we set out to evaluate whether IGF-I stimulation may affect DDR1 expression. Indeed, in breast cancer cells (MCF-7 and MDA-MB-231) IGF-I induced significant increase of DDR1 protein expression, in a time and dose dependent manner. However, we did not observe parallel changes in DDR1 mRNA. DDR1 …
