Indirect Aggression And Victimization: Investigating Instrument Psychometrics, Gender Differences, And Its Relationship To Social Information Processing, Taylor Steeves

Electronic Theses and Dissertations

The study of indirect bullying behaviors, relational aggression and social aggression, has been of theoretical importance and interest to researchers and psychologists within the last few decades. In this investigation, using a convenience sample of 451 late adolescents attending a private university in the mid-Atlantic U.S., I examined the factor structure of two measures of indirect bullying, the Young Adult Social Behavior Scale – Victim (YASB-V) and the Young Adult Social Behavior Scale – Perpetrator (YASB-P). Using confirmatory factor analysis (CFA), I found that the YASB-V comprised a four-factor model, differing from the model that had been identified in the …

Conceptions Of Rurality: Examining Beliefs And Their Impact On Teacher Efficacy In A Small Appalachian School, Lori Wickham

Electronic Theses and Dissertations

The current literature documents the historical peripheralization of rural communities and the deficit narratives often imposed upon their schools, students and families. Research further suggests this history of peripheralization is often internalized by those identifying with these communities and that this internalization of deficit orientations may be impacting perceptions of possibility in educational practice. This mixed-methods study investigates more thoroughly if and how these core-periphery dynamics manifest in a small Appalachian school by examining possible connections between educators’ beliefs regarding rurality and their sense of teacher and collective efficacy. The research was guided by the following question:

How do rural …

Population Inference Of Non-Spinning Eccentric Binary Black Holes, Muhammad Zeeshan

Theses

Compact binary mergers produce gravitational waves (GWs), which carry information about their sources. The LIGO-VIRGO-KAGRA network detects GWs signals, and we use those measurements to infer BBHs population properties such as mass, spin, and eccentricity distribution in the universe. Binary component masses and spins are well-known to provide insight into the source formation, evolution, and environment. Unlike these two, eccentricity is a unique and measurable signature of strongly interacting events. Unfortunately, most available parameter estimation results for GWs signals do not include eccentricity: models for binary merger with eccentricity have minimal availability and parameter coverage. Therefore, to assess how well …

Design Of Stormwater Bmps For Surface And Groundwater Protection Based On Site-Scale Soil Properties: Phase I, Kelly Kibler, Lisa Chambers, Melanie Beazley

Florida DOT

Much of Earth’s nutrient cycling takes place in soils. Characteristics of soils control physical, chemical, and biological processes that determine rates of nutrient fluxes, storage, or transformation. As remediation of excess nutrients in stormwater runoff is one function of stormwater Best Management Practices (BMPs), the soil profile constitutes one of the most important factors of BMP design. Variation observed in BMP effectiveness (e.g., why one BMP design works effectively in one place and not another) can often be explained by variations in the soil profile, either through direct means or by a soil’s influence on hydraulics of stormwater flow through …

On The Evaluation Of Entropy Threshold For Debonding During Crack Prorogation Using Dic Technique, A. Mahmoudi, M. R. Khosravani, M. M. Khonsari, Tamara Reinicke

Faculty Publications

The accumulated entropy at the crack tip of a semi-circular bending (SCB) specimen is investigated to obtain a threshold for material fracture and interatomic debonding. The presented approach uses the experimental data obtained from the Digital Image Correlation (DIC) technique and strain maps superposed to SCB specimens to measure the plastic flow at the crack tip. The Swift strain hardening model is utilized to calculate the stress domain at the crack tip and, consequently, the plastic strain energy and entropy accumulation. Results show that the crack surface propagates when the generated entropy at the crack tip reaches a critical limit. …

Can Gulf Ribbed Mussels Enhance Coastal Restoration Projects In A Future With Climate Change?, Skylar Liner

LSU Master's Theses

Living shorelines present one restoration approach using biotic elements (via ecosystem engineers) to stabilize shorelines and increase valuable habitat. Gulf ribbed mussels (Geukensia granosissima) are important ecosystem engineers within brackish and salt marshes in the northern Gulf of Mexico, and can increase nutrient availability, enhance marsh vegetation production, and potentially improve shoreline stability. It is unknown whether mussels will maintain these functions as future climate change predicts increases in temperature and water level, which may exceed the mussel’s tolerance. A field survey conducted during the summer of 2022 identified the daily maximum temperature at the marsh surface, where mussels naturally …

Cloning A Fusion Gene For The Identification Of The Proteins Contained In Ubiquitin-Rich Condensates, Grace M. Whitehead

Undergraduate Honors Theses

Cellular liquid-liquid phase separation (LLPS) is a mechanism by which membraneless organelles such as polyubiquitinated condensates form and function. A non-receptor tyrosine kinase, Tnk1, binds to the polyubiquitin of polyubiquitinated condensates that are labeled for the proteasome for autophagy through its ubiquitin association (UBA) domain. This tyrosine kinase has links to a subset of hematological cancers, so identifying the protein contents within polyubiquitinated condensates is essential for understanding their significance in cancer pathways and to eventually identify potential therapeutic targets. This honors thesis focuses on the cloning of a fusion gene, pcDNA3.1 mNeonGreen–V5–UBA, as well as its deactivated L36D variant, …

We report the first detection of a TeV γ-ray flux from the solar disk (6.3σ), based on 6.1 years of data from the High-Altitude Water Cherenkov (HAWC) observatory. The 0.5-2.6 TeV spectrum is well fit by a power law, dN/dE=A(E/1 TeV)-γ, with A=(1.6±0.3)x10-12 TeV-1 cm-2 s-1 and γ=3.62±0.14. The flux shows a strong indication of anticorrelation with solar activity. These results extend the bright, hard GeV emission from the disk observed with Fermi-LAT, seemingly due to hadronic Galactic cosmic rays showering on nuclei in the solar atmosphere. However, current theoretical models are unable to explain the details of how solar …
