Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire

Masters Theses

Previous studies have identified that changes in plant phenology are most likely induced by climate variability. One such change is the end of season (EOS) for deciduous forests in the United States. In essence, the EOS represents the end of plant productivity for a given year; the phase in which plant dormancy is reached. However, our wealth of knowledge on plant phenology largely overlooks the phases that occur in autumn, especially the EOS, with many previous studies focusing on spring phenology. This study uses remote sensing MODIS aerial imagery data and historical meteorological data to analyze any relationships that may …

Self-Reflections Through A Screen: Self-Identity, Social Media, And Psychological Well-Being, Jeremy J. Serio

Undergraduate Honors Thesis Collection

Social media use among emerging adults is assumed to be related to a variety of negative psychological outcomes and has, in recent years, become a widely studied phenomenon (Kim, 2017, Pew Research Center, 2018). Despite the widespread assumption, the results from empirical studies of the effects of social media use on mental health in this population have been inconsistent and inconclusive (Keles et al., 2020, Yang et al., 2021). Several meta-analyses (e.g., Keles et al., 2020) demonstrate these inconsistent results across studies and point to the need to consider individual difference factors when researching this issue. Different self-identity styles have …

The Floral Thermal Environment: Physical, Morphological, And Environmental Determinants, And Their Impact On Plant-Pollinator Interactions, Jennifer Apland

All Theses

Anthropogenic climate change is driving major shifts in global temperatures and increases in extreme temperature events that contribute to reduced survival and species loss. To counteract extreme temperatures, many organisms can undergo geographic range shifts or engage in behavioral thermoregulation (e.g., movement to suitable microhabitats). While plants are sessile and thus subject to highly variable ambient temperatures, they have evolved mechanisms to regulate internal floral temperature. Floral thermoregulation may mitigate thermal stress on pollen and ovules and impact plant-pollinator interactions. These mechanisms for thermoregulation are often highly dependent on ambient temperature and solar radiation as most plants are not endothermic. …

Fabrication Of Novel Electropolymerized Conductive Polymer Of Hydrophobic Perfluorinated Aniline As Transducer Layer On Glassy Carbon Electrode: Application To Midazolam As A Model Drug Of Benzodiazepines, Ekram Hany Mohamed, Amr Mahmoud,, , Nancy Nashat, Sally El-Mosallamy

Pharmacy

The objective of this study is to fabricate solid-contact ion selective electrodes (SC-ISEs) that have long term stable potential. Various conducting polymers such as polyaniline and its derivatives have been successfully employed to improve the potential stability in SC-ISEs. Recently, the role of hydrophobicity at the interface between the conducting polymer solid contact and the ion sensing membrane has been investigated and figured out that the hydrophobic interfaces preclude water layer formation that deteriorate the SC-ISEs potential stability and reproducibility. In this work, a hydrophobic polyaniline derivative was fabricated on the surface of a glassy carbon electrode by electropolymerization of …

Open Access Theses & Dissertations

Lizard communities in arid lands can act as model systems of how diversity and abundance are impacted in the face of ongoing climate variability and change, as they are sensitive to shifts in precipitation, temperature, and changing vegetation structure. The main research question we hope to answer is how the community composition of lizards varies between dominant vegetation types (Mesquite dunes, grasslands, and Creosote Bush flats). Nine sites (3 of each dominant vegetation type) with 16 pitfall traps each (n = 144) were surveyed from June 2016 -- June 2017. 12 lizard species were captured, consisting of 923 total captures …

Proteomic Analysis Reveals Fkbp51 And Fkbp52 Interactors Implicated In Androgen Receptor-Mediated Castration Resistant Prostate Cancer, Olga Soto

Open Access Theses & Dissertations

Aberrant signaling mechanisms by the Androgen Receptor (AR) are attributed as the main culprits for the initiation and progression of prostate cancer (PCa). Due to its dependence on androgens, research efforts have focused on developing strategies to directly target androgen-mediated receptor activity. However, given the recurrence and treatment resistance of PCa despite androgen targeted therapies, recent efforts have shifted to find novel targets against the disease. These efforts include further revealing the molecular components and their mechanisms underlying AR signaling in both normal and disease physiological settings. Hence, our lab's work is focused on characterizing and targeting molecular chaperones that …

Towards A Spaceworthy Cots Graphics Processing Unit: Hardware Performance Counter Based Symptomatic Fault Detection, Antonio E. Teijeiro

Open Access Theses & Dissertations

Ionizing radiation remains an obstacle to bringing graphics processing units (GPU) to space. Since radiation-hardened GPU chips are technically infeasible at the moment, an emphasis has been placed on the adaptation of commercial-off-the-shelf (COTS) GPUs to the space domain. At present, GPU error detection methods require redundant computation. This thesis work explores the utilization of hardware performance counters, special registers useful for monitoring internal GPU hardware events, for symptom-based, lightweight error detection. Hardware performance counters are successfully utilized for the detection of anomalous single event upsets in the L0 instruction cache, the load store unit, the arithmetic and logic unit, …

Village-Level Processing Of Pangi (Pangium Edule Reinw.) Seeds By The Obu Manuvu Improves The Edibility And Level Of Some Nutritional Factors [Research Note], Rovi Gem E. Villame-Gayagas, Jennifer P. Fronteras, Maria Christna D. Nacar, Aaron P. Lorilla, Pedro A. Alviola Iv

The Philippine Agricultural Scientist

Pangi (Pangium edule Reinw) seed is known to be a poisonous material. However, it becomes safe for consumption after processing. This study determined the effect of village-level processing by the Obu Manuvu community of Marilog District, Davao City, Philippines on the antinutrient and nutritional composition of Pangi seeds. Processing methods involved washing with running water for about 15 s, boiling in water for 30 min, and soaking in flowing water in a nearby river overnight. Results showed that after processing, the levels of antinutrients such as cyanogenic glycosides and oxalates were reduced significantly (p < 0.05) by 99.15% and 78.23%, respectively. Further, the tannin content was also significantly reduced by 96.15%. The crude fat content significantly increased (p < 0.05) by about 54%. Crude ash and fiber decreased, while protein did not change significantly (p < 0.05). Minerals such as calcium and zinc increased (p < 0.05) by 221.43% and 64.39%, respectively while the iron and manganese levels remained unaffected. Findings of the study suggested that the processing method by the Obu Manuvu effectively reduces the level of antinutrients, thereby improving the edibility and safety of Pangi seeds. Further, the processing method improves the level of some nutrients, specifically crude fat, calcium, and zinc.

Controls Of Benthic Microbial Communities In Headwater Streams Across A Land Use Gradient In Northeastern Usa, Joshua Michael Buonpane

Master's Theses and Capstones

Benthic microbes are important drivers of biogeochemical cycling in streams, influencing the storage, transformation, and emission of carbon and nutrients. While the impact of land use and land cover on water quality has been extensively studied, the connection between water quality and microbial community composition and function remains unresolved. In this study, we examined how the water quality changes accompanying watershed development impact the diversity, composition, and functional potential of benthic bacterial/archaeal, and fungal communities. This was explored in headwater streams across an urbanization gradient in the northeastern US. We did not find a link between urbanization and α-diversity of …

Open Access Theses & Dissertations

Chagas disease (CD), caused by the protozoan parasite Trypanosoma cruzi, affects 7-8 million people worldwide. Lately, the disease has been spread to nonendemic countries and regions, like the U.S. and Europe. The disease can be divided into two phases: the acute and chronic phases, which continue for years or even decades. There are two available drugs for CD treatment: benznidazole (BNZ) and nifurtimox (NFX). These drugs are highly effective in the acute phase but less efficient in the chronic stage. Other limitations of these drugs are their toxicity, leading to serious adverse events and premature treatment termination. Newer clinical trial …

Parent-Child Communication About Adoption From The Adopted Child's Perspective: A Literature Review, Abigial Kent

All Graduate Reports and Creative Projects, Fall 2023 to Present

Discourse in adoptive families is how families create relationships and familial identity. This literature review addresses how parents talk to adoptees and the negative and positive outcomes of these conversations. Parents discuss entrance stories, word choice, and privacy management with their adopted children. When parents are open with adoptees, adoptees are better adjusted and have a strong sense of identity. Parents who had good quality conversations with their children saw children who had a stronger sense of belonging. When parents withhold information, adoptees developed anxious and avoidant attachment styles. Adoptees also felt betrayed and lost trust in their adopted parents. …

Waterbody Size Influences Chemical And Community Characteristics Of North Dakota Prairie Wetlands And Lakes, Julia Renee Hampton

Theses and Dissertations

The Prairie Pothole Region (PPR) of North America is home to dynamic glacier-formed lakes and wetlands that range in size from small intermittent wetlands to large permanently filled basins. Predicting water-related shifts in environmental conditions and biological community responses within these systems has been challenging due to non-linear, scale-specific changes. Furthermore, landscape-level changes in the quantity and distribution of surface water are becoming more frequent. This thesis contributes to our understanding of how waterbody size, and potential size fluctuations, influence chemical and community dynamics of complex PPR glacial lakes and wetlands. We paired remote sensing and discontinuity methods with US …

Language As The Catalyst Between The Relationship Of Subordinates' Communicative Competence And Supervisors' Communicative Behavior: A Canonical Correlation Analysis, Lindsey N. Tan

Journal of English and Applied Linguistics

Communicative competence could be understood as the ability to effectively use language in different contexts, and one of these contexts is the intricate framework of the supervisor-subordinate relationship (SSR). However, studies on SSR are mostly based on supervisors’ communicative behavior (SCB), and there is a scarcity of studies that investigate the role of subordinates’ organizational communication competence (SOCC) on SSR. Consequently, this study aims to investigate the relationship between SOCC and SCB in the SSR framework. Using the canonical correlation analysis, two sets of facets were used to analyze the relationship. The first set is the SOCC, which includes communicative …
