Paradox Lost: Wide Gape In The Ordovician Brachiopod Rafinesquina Explains How Unattached Filter-Feeding Strophomenoids Thrived On Muddy Substrates, Benjamin F. Dattilo, Rebecca L. Freeman, Kyle Hartshorn, David Peterman, Aaron Morse, David L. Meyer, Lindsay G. Dougan, James W. Hagadorn

Earth and Environmental Sciences Faculty Publications

Strophomenoid brachiopods had thin, concavo-convex shells, were ubiquitous colonizers of Palaeozoic muddy seafloors, and are hypothesized to have filter-fed in a concave-upward orientation. This orientation would elevate their line of commissure out of potentially lethal lophophore-clogging mud. The paradox is that epi- biont distributions on strophomenoids support a convex-upward life position, as do studies of strophome- noid stability and trace fossils formed by strophomenoid sediment-clearing. A premise of the concave-upward orientation hypothesis is a narrow gape, which causes narrow, high velocity inhalant currents, leaving strophomenoids vul- nerable to sediment entrainment. Herein we investigate the gape angle of Rafinesquina using serial …

Exploring The Interrelationship Between Anxiety, Academic Apathy, And Avoidance In Community College Students, Katey R. Leverson

Education Doctorate Dissertations

The purpose of this quantitative study was to investigate aspects of mental health and the approaches students take when coping with stress. Specifically, this study sought to understand the interrelationship between anxiety levels, feelings of academic apathy, and the use of avoidance coping strategies. Students from seven public, two-year colleges within a Midwest college and university system served as this study’s sample. Data collection took the form of a non-experimental self-report structure and included the use of three empirically established and valid measures: The Self-rating Anxiety Scale (SAS), Bresso’s Academic Burnout Questionnaire, and the Coping Inventory for Stressful Situations (CISS). …

Contributions Of Mouse Genetic Strain Background To Age-Related Phenotypes In Physically Active Het3 Mice., Jake W Willows, Zahra Alshahal, Naeemah M Story, Michele J Alves, Pablo Vidal, Hallie Harris, Rochelle Rodrigo, Kristin I Stanford, Juan Peng, Peter C. Reifsnyder, David E Harrison, W David Arnold, Kristy L Townsend

Faculty Research 2024

We assessed aging hallmarks in skin, muscle, and adipose in the genetically diverse HET3 mouse, and generated a broad dataset comparing these to individual animal diagnostic SNPs from the 4 founding inbred strains of the HET3 line. For middle- and old-aged HET3 mice, we provided running wheel exercise to ensure our observations were not purely representative of sedentary animals, but age-related phenotypes were not improved with running wheel activity. Adipose tissue fibrosis, peripheral neuropathy, and loss of neuromuscular junction integrity were consistent phenotypes in older-aged HET3 mice regardless of physical activity, but aspects of these phenotypes were moderated by the …

Network-Based Analysis Predicts Interacting Genetic Modifiers From A Meta-Mapping Study Of Spike-Wave Discharge In Mice., Montana Kay Lara, Jeffrey L Brabec, Amanda E Hernan, Rod C Scott, Anna L. Tyler, J Matthew Mahoney

Faculty Research 2024

Absence seizures are characterized by brief lapses in awareness accompanied by a hallmark spike-and-wave discharge (SWD) electroencephalographic pattern and are common to genetic generalized epilepsies (GGEs). While numerous genes have been associated with increased risk, including some Mendelian forms with a single causal allele, most cases of GGE are idiopathic and there are many unknown genetic modi- fiers of GGE influencing risk and severity. In a previous meta-mapping study, crosses between transgenic C57BL/6 and C3HeB/FeJ strains, each carrying one of three SWD-causing mutations (Gabrg2 tm1Spet(R43Q), Scn8a8j or Gria4spkw1), demonstrated an antagonistic epistatic interaction between loci on mouse chromosomes 2 and …

Consumer Preferences For Wood-Pellet-Based Green Pricing Programs In The Eastern United States, Sydney Oluoch, Pankaj Lal, Andres Susaeta, Meghann Smith, Bernabas Wolde

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Co-firing wood pellets with coal is an attractive alternative energy generation method with economic, social, and environmental benefits for the US energy generation sector. One way to sustainably use wood pellets for co-firing is to create consumer-supported green pricing programs (GPPs). Our study surveyed residents of five states (Alabama, New Jersey, New York, Pennsylvania, and Virginia) to investigate preferences for the attributes of a hypothetical GPP. The study applied the Best Worst Choice method, which employs the Best Worst Scaling (BWS) and binary choice (BC) task. The BWS analysis showed that residents of all five states most value the flexibility …

Evaluating The Role Of Titanomagnetite In Bubble Nucleation: Rock Magnetic Detection And Characterization Of Nanolites And Ultra-Nanolites In Rhyolite Pumice And Obsidian From Glass Mountain, California, Stefanie Brachfeld, Kelly N. Mccartney, Julia E. Hammer, Thomas Shea, Thomas Giachetti

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

We document the presence, composition, and number density (TND) of titanomagnetite nanolites and ultra-nanolites in aphyric rhyolitic pumice, obsidian, and vesicular obsidian from the 1060 CE Glass Mountain volcanic eruption of Medicine Lake Volcano, California, using magnetic methods. Curie temperatures indicate compositions of Fe2.40Ti0.60O4 to Fe3O4. Rock-magnetic parameters sensitive to domain state, which is dependent on grain volume, indicate a range of particle sizes spanning superparamagnetic (< 50–80 nm) to multidomain (>10 μm) particles. Cylindrical cores drilled from the centers of individual pumice clasts display anisotropy of magnetic susceptibility with prolate fabrics, with the highest degree of anisotropy coinciding with the highest vesicularity. Fabrics …

Evaluating The Role Of Titanomagnetite In Bubble Nucleation: Novel Applications Of Low Temperature Magnetic Analysis And Textural Characterization Of Rhyolite Pumice And Obsidian From Glass Mountain, California, Kelly N. Mccartney, Julia E. Hammer, Thomas Shea, Stefanie Brachfeld, Thomas Giachetti

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Nucleation of H2O vapor bubbles in magma requires surpassing a chemical supersaturation threshold via decompression. The threshold is minimized in the presence of a nucleation substrate (heterogeneous nucleation, < 50 MPa), and maximized when no nucleation substrate is present (homogeneous nucleation, >100 MPa). The existence of explosively erupted aphyric rhyolite magma staged from shallow (< 100 MPa) depths represents an apparent paradox that hints at the presence of a cryptic nucleation substrate. In a pair of studies focusing on Glass Mountain eruptive units from Medicine Lake, California, we characterize titanomagnetite nanolites and ultrananolites in pumice, obsidian, and vesicular obsidian (Brachfeld et al., 2024, https://doi.org/10.1029/2023GC011336), calculate titanomagnetite crystal number densities, and compare titanomagnetite abundance with the physical properties of pumice to evaluate hypotheses on the timing of titanomagnetite crystallization. Titanomagnetite crystals with grain sizes of approximately 3–33 nm are identified in pumice samples from the thermal unblocking of low-temperature thermoremanent magnetization. The titanomagnetite number densities for pumice are 10¹⁸ to 10²⁰ m⁻³, comparable to number densities in pumice and obsidian obtained from room temperature methods (Brachfeld et al., 2024, https://doi.org/10.1029/2023GC011336). This range exceeds reported bubble number densities (BND) within the pumice from the same eruptive units (average BND ∼4 × 10¹⁴ m⁻³). The similar abundances of nm-scale titanomagnetite crystals in …

Hydroclimatic Trends And Streamflow Response To Recent Climate Change: An Application Of Discrete Wavelet Transform And Hydrological Modeling In The Passaic River Basin, New Jersey, Usa, Felix Oteng Mensah, Clement Aga Alo, Duke Ophori

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The exigency of the current climate crisis demands a more comprehensive approach to addressing location-specific climate impacts. In the Passaic River Basin (PRB), two bodies of research—hydroclimatic trend detection and hydrological modeling—have been conducted with the aim of revealing the basin’s hydroclimate patterns as well as the hydrologic response to recent climate change. In a rather novel application of the wavelet transform tool, we sidelined the frequently used Mann–Kendal (MK) trend test, to identify the hidden monotonic trends in the inherently noisy hydroclimatic data. By this approach, the use of MK trend test directly on the raw data, whose results …

Animal Plaintiffs, Matthew Liebman

Minnesota Law Review Vols. 106:2 onward (2021-present)

From endangered Hawaiian songbirds to dolphins deafened by Navy sonar to a neglected horse named Justice, nonhuman animals increasingly appear as plaintiffs in lawsuits alleging their subjection to extinction, abuse, and other injustices. These cases are far more than mere novelties or publicity stunts; they raise important jurisprudential questions about what it means to be a plaintiff seeking relief. As we learn more about the richness and diversity of nonhuman life, our legal system will have to rethink its exclusions to meet the demands of interspecies justice. Drawing on a diverse body of philosophical, jurisprudential, and scientific scholarship, this Article …

Implementing A New Clinical Note Template To Reduce Documentation Burden At A Pediatric Organization, Nikki Blaze

Translational Projects (Open Access)

Clinical notes of a patient’s visit to a healthcare provider are necessary for patient care, reimbursement, and regulatory compliance with federal and state laws. Over time, non-standardized processes within the EHR have led to the increasing use of copy-paste to complete clinical notes, leading to irrelevant information being captured in the notes. Sinsky et al. (2020) shared that 49% of physicians' time is spent within the EHR, completing their documentation, placing orders, and reviewing the patient's chart. The documentation requirements for billing and coding created tension as clinicians sought ways to reduce the documentation burden. To reduce the documentation burden …

Prevalence Of Adverse Childhood Experiences And Its Dose-Response Association With Anxiety-Related Stress Symptoms In Young Adults Ages 18 To 44 Years Old In The United States, Kenechukwu O. Nwosu

Dissertations and Theses (Open Access)

Introduction: Adverse childhood experiences are common in the United States with about 64% of the population affected. Adverse childhood experiences are predictors of many chronic diseases including mental illnesses like anxiety. Though non-Hispanic whites are mostly afflicted by anxiety compared to their racial counterparts, minority races like non- Hispanic Black/African Americans disproportionately suffer more dire consequences due to the chronicity of untreated conditions which often result from lack of access to care among other barriers. Methods: This is a retrospective cross-sectional study. BRFSS 2022 data set was used to identify 56,598 respondents, ages 18 to 44 years old for analysis. …

Digital Journal of Clinical Medicine

Skeletal dysplasia encompasses a spectrum of over 400 rare inheritable skeletal abnormalities typically manifested early in childhood. Hypertrophic Osteoarthropathy is a clinical syndrome marked by abnormal skin and osseous tissue proliferation at the distal extremities. It is characterized by unique clinical features such as digital clubbing, periostosis of tubular bones, and synovial effusions.

We report three cases of HPOA for further understanding and insight into this infrequent cause of clubbing. Case 1 involved a 25-year-old male presenting with joint pain, primarily in wrists and knees, accompanied by progressive swelling in both lower limbs for the past 3 years. Case 2 …

Understanding University Support For Suicide Bereavement And Bereaved Experiences: A Phenomenological Study, Kristin May Anderson, Neishamia B. Kayizzi, Brittany M. Lee, Addalee K. Lyon

LMU Theses and Dissertations

In recent years, a multitude of literature have discussed the turbulent nature for young adults to navigate the difficulties of suicide bereavement with lack of support. This experience can be further cumbersome when the bereavement is co-occurring within an academic profession, such as attending university. This study explored three participants experience of suicide bereavement support at a university level, utilizing a phenomenological arts-based approach for inquiry. Data analysis revealed eight common themes that reflect the university students' lived experiences of the phenomenon discussed: Acknowledgment of the communicated loss by faculty, provision of academic support, lack/absence of practice, reluctance, emotional response, …
