The Moderating Effect Of Organizational Identification And Supervisor’S Organizational Embodiment On Unethical Pro- Organizational Behavior, Taylor Morgan Flinn

Theses and Dissertations

Unethical pro-organizational behavior (UPB) are behaviors that are illegal/immoral but are engaged in with the intention of benefiting their organization. The present study sought to investigate the moderating relationships of organizational identification (OI) and supervisor’s organizational embodiment (SOE), with work engagement as a predictor. The results revealed that there was a weak correlation between work engagement and UPB as well as SOE and UPB. Both OI and SOE did not moderate the relationship between work engagement and UPB. The current study contributed to the literature on predictors of UPB, as work engagement has rarely been used as a predictor of …

Twist-Assisted All-Antiferromagnetic Tunnel Junction In The Atomic Limit, Yullang Chen, Kartik Samanta, Naafls A. Shahed, Haojle Zhang, Chi Fang, Arthur Ernst, Evgeny Y. Tsymbal, Stuart S.P. Parkin

Nebraska Center for Materials and Nanoscience: Faculty Publications

Antiferromagnetic spintronics^1,2 shows great potential for high-density and ultrafast information devices. Magnetic tunnel junctions (MTJs), a key spintronic memory component that are typically formed from ferromagnetic materials, have seen rapid developments very recently using antiferromagnetic materials3,4. Here we demonstrate a twisting strategy for constructing all-antiferromagnetic tunnel junctions down to the atomic limit. By twisting two bilayers of CrSBr, a 2D antiferromagnet (AFM), a more than 700% nonvolatile tunnelling magnetoresistance (TMR) ratio is shown at zero field (ZF) with the entire twisted stack acting as the tunnel barrier. This is determined by twisting two CrSBr monolayers for which the TMR …

Mathematics, Physics, and Computer Science Faculty Articles and Research

A response of global seismic activity to the geomagnetic storms of St. Patrick’s Day (March 17) in 2013 and 2015 is investigated. These two storms occurred during nearly identical storm sudden commencement times and similar solar flux levels. We have revealed a rather similar pattern of the most substantial earthquakes that have occurred since these storms. Two major crust continental earthquakes, in Iran (M = 7.7), 16 April 2013, and in Nepal (M = 7.8), 25 April 2015, have occurred with a time delay of ~30 and ~39 days after geomagnetic storm onsets in 2013 and 2015, respectively. After that, …

Deep Space Observations Of Conditionally Averaged Global Reflectance Patterns, Alexander Kostinski, Alexander Marshak, Tamás Várnai

Michigan Tech Publications

The Deep Space Climate Observatory (DSCOVR) spacecraft drifts about the Lagrangian point ≈ 1.4 − 1.6 × 106 km from Earth, where its Earth Polychromatic Imaging Camera (EPIC) observes the entire sunlit face of Earth every 1–2 h. In an attempt to detect “signals,” i.e., longer-term changes and semi-permanent features such as the ever-present ocean glitter, while suppressing geographic “noise,” in this study, we introduce temporally and conditionally averaged reflectance images, performed on a fixed grid of pixels and uniquely suited to the DSCOVR/EPIC observational circumstances. The resulting images (maps), averaged in time over months and conditioned on surface/cover type …

Development And Characterization Of Automated Screen Mesh-Based Microfluidic Device To Perform Continuous Countercurrent Liquid-Liquid Extraction, Quinn Mcculloch

Nanoscience and Microsystems ETDs

Continuous Countercurrent Microfluidic Liquid-Liquid Extraction (CC-MLLE) shows tremendous potential to generate large numbers of equilibrium stages of separation in a small footprint, with a minimum of pumping, valving, and phase separation steps. However, CC-MLLE rarely appears in literature because it requires a delicate balance between capillary and hydrodynamic forces for deterministic flow.

This dissertation showcases a patented screen mesh-based CC-MLLE invention that performs stable, long-duration (> 36 hr.), countercurrent liquid-liquid extraction and achieves 37 equilibrium stages within a 38.5 μl internal volume. The device is fabricated from chemically resistant polyetheretherketone plastic, using standard machine shop equipment, a plotting cutter, screen …

Parg Is Essential For Polθ-Mediated Dna End-Joining By Removing Repressive Poly-Adp-Ribose Marks, Umeshkumar Vekariya, Leonid Minakhin, Gurushankar Chandramouly, Mrityunjay Tyagi, Tatiana Kent, Katherine Sullivan-Reed, Jessica Atkins, Douglas Ralph, Margaret Nieborowska-Skorska, Anna-Mariya Kukuyan, Hsin-Yao Tang, Richard T. Pomerantz, Tomasz Skorski

Department of Biochemistry and Molecular Biology Faculty Papers

DNA polymerase theta (Polθ)-mediated end-joining (TMEJ) repairs DNA double-strand breaks and confers resistance to genotoxic agents. How Polθ is regulated at the molecular level to exert TMEJ remains poorly characterized. We find that Polθ interacts with and is PARylated by PARP1 in a HPF1- independent manner. PARP1 recruits Polθ to the vicinity of DNA damage via PARylation dependent liquid demixing, however, PARylated Polθ cannot perform TMEJ due to its inability to bind DNA. PARG-mediated de-PARylation of Polθ reactivates its DNA binding and end-joining activities. Consistent with this, PARG is essential for TMEJ and the temporal recruitment of PARG to DNA …

Using Monte Carlo simulations, we investigate the properties of sequentially calculated Bayesian P-values under various conditions, comparing them to frequentist counterparts. Our findings demonstrate advantages including incorporation of prior knowledge, continuous evidence measurement, and adaptability to accumulating data. We explore computational challenges, propose optimized algorithms, and address the impact of prior specification, providing guidelines for choosing appropriate priors. This research contributes to the ongoing discussion about P-values in scientific inference and offers a practical framework for researchers adopting Bayesian methods in sequential analyses. …

P-Adic Quantum Mechanics, The Dirac Equation, And The Violation Of Einstein Causality, Wilson A. Zuniga-Galindo

School of Mathematical & Statistical Sciences Faculty Publications

This article studies the breaking of the Lorentz symmetry at the Planck length in quantum mechanics. We use three-dimensional ℘-adic vectors as position variables, while the time remains a real number. In this setting, the Planck length is 1/℘, where ℘ is a prime number, and the Lorentz symmetry is naturally broken. In the framework of the Dirac-von Neumann formalism for quantum mechanics, we introduce a new ℘-adic Dirac equation that predicts the existence of particles and antiparticles and charge conjugation like the standard one. The discreteness of the ℘-adic space imposes substantial restrictions on the solutions of the new …

Artificial Carbon Sequestration In Utah, Signee Storrud, Kendall Becker, Scott Hotaling

All Current Publications

Carbon dioxide is an important greenhouse gas that helps keep Earth warm and habitable. But since humans began burning large quantities of fossil fuels during the Industrial Revolution, there has been a rapid increase in atmospheric carbon dioxide from approximately 280 parts per million in 1750 to more than 420 parts per million in 2024. Natural carbon storage processes have been unable to keep up with humans’ carbon dioxide emissions, and the sudden rise in atmospheric carbon dioxide has led to rapid global warming and climate change.

Improvements In Computational Techniques For Determining Ideal Class Groups And Class Numbers, Muhammed Rashad Erukulangara

USF Tampa Graduate Theses and Dissertations

The ideal class group is a fundamental concept in algebraic number theory, providing insights into the structure and factorization properties of the ring of integers of a number field. It measures the extent to which unique factorization fails in the ring of integers. Efficiently computing the ideal class group is crucial for exploring unproved heuristics in number theory and solving Diophantine equations. Additionally, the computation of the ideal class group has several cryptographic applications, such as schemes based on the Discrete Logarithm Problem (DLP), the computation of isogenies, and groups of unknown order. Despite its importance, much about the ideal …

Historical Structural Analysis Of The Rileyville Quadrangle, Page County, Virginia, Sydney Fergen

2024 Symposium

The Northwest corner of Virginia, within the Appalachian Mountains, formed during a collision of continents called the Alleghenian Orogeny roughly 250 million years ago(Ma). This event caused tectonic plates to collide, reforming the fractured continental crust back into a new supercontinent, Pangaea. This process took over 100 Ma and closed the Rheic Ocean. These large-scale compressional tectonics had several effects including formation of the Allegheny Plateau and Taconic Mountain range, which has gradually eroded exposing a series of plunging folds and imbricated thrust faults. This poster presents a structural analysis of the Rileyville quadrangle to help decipher regional geologic history …

U/Pb Zircon Ages Of Saltese Upland Conservation Area, Priest River Core Complex, Jessica M. Lawrence, Natalie Potter, Chad Pritchard

2024 Symposium

The Saltese Upland Conservation Area provides a window into the Priest River Core Complex with Lake Hauser gneiss grading to migmatite, garnet-baring amphibolite juxtaposed with felsite to orthogneiss rocks. U/Pb ages from LA-ICP-MS of separated zircon grains show trends very similar to detrital 207Pb/206Pb ages of the Belt Supergroup. The amphibolite displays a much stronger peak at 1.4 to 1.5 Ga , possibly related to the emplacement of Mesoproterozoic dikes. The amphibolite and granitic rocks also contain a number of grains with 238U/206Pb around 60 Ma preserving events from the uplift of the Priest River Complex in the Spokane area. …

Paleohydraulic Analysis Of Megaripples From Outburst Floods In Omak, Washington, Jessica M. Lawrence
