Accurate chemical compositions of star-forming regions provide a critical diagnostic tool for characterizing the star formation history and gas flows that regulate galaxy formation. However, the abundance discrepancy factor (ADF) between measurements derived from the “direct” optical electron temperature (T_e ) method and those from recombination lines (RLs) introduces a ∼0.2 dex systematic uncertainty in the oxygen abundance. The degree of uncertainty for other elements is unknown. We conduct a comprehensive analysis of O⁺⁺ and N⁺ ion abundances using optical and far-infrared (far-IR) spectra of a star-forming region within the nearby dwarf galaxy Haro 3, which exhibits …

Bodies At Risk When Choice Is A Privilege: Women’S Reproductive Healthcare Accessibility And Health Outcomes Since The Dobbs (2022) Ruling, Dallas Bonnet

Undergraduate Theses

Existing literature has well-documented the disproportionate effects of abortion restrictions upon socioeconomically disadvantaged women and women of color. This thesis builds on that work by exploring the relationship between state-level abortion restrictions and women’s self-reported health, as well as state-level infant mortality rates and maternal mortality rates. This project breaks these relationships down into three separate studies: Study 1 investigates the effect that abortion restrictions have on women’s self perceptions of health. Study 2 assesses the impact of abortion restrictions on infant mortality rates. Study 3 inspects the impact of abortion restrictions on maternal mortality rates. The primary independent variable …

Hands Free Policy Brief, Ryan E. Spohn, Justin Nix, Sadaf Hashimi, Travis Carter, Seth Goldsmith, Nikolas Hahn

Reports

Owning a motor vehicle and a smartphone are modern conveniences that most Nebraskans were accustomed to by 2024. 1 The combination has, however, proven to be a modern challenge for roadway safety. Traffic crashes stemming from cellphone distractions have increased steadily since 2016, and traffic fatalities have fared no better since 2019. 2 Cellphone laws restricting the use of cellular devices while operating a motor vehicle may offer some relief. Although most states, including Nebraska, have text-messaging bans, others have begun instituting additional legislative mandates prohibiting cellphones while driving—often termed a hands-free policy (HFP). The purpose of this policy brief …

Fenced And Feral: Farming And Spread Of Flowerhorn (Amphilophus Spp.) In Lake Sampaloc, Philippines, Janice A. Ragaza, Hannah Nicole Gasmen

Environmental Sustainability

This study examines the spread and ecological impact of invasive Flowerhorn cichlids (Amphilophus spp.) in Lake Sampaloc, Philippines, driven by both accidental release and intentional aquaculture practices. Field observations and literature reveal that these highly adaptable and aggressive fish outcompete native species, contributing to biodiversity decline amid increasing pollution, eutrophication, and microplastic contamination. Their phenotypic plasticity allows them to thrive in degraded environments, further exacerbating ecological imbalance. While local communities have begun utilizing Flowerhorns for ornamental trade and potential aquafeed production, such practices risk reinforcing their proliferation. The study highlights the need for integrated management strategies combining biosecurity, pollution control, …

Pressed For Time: The Role Of Time Pressure And Attentional Awareness On The Mental Health Of Employed Informal Dementia Caregivers, Kate Bishop

University Honors Theses

Informal caregivers for individuals with Alzheimer’s and related dementias (ADRD) experience increased time demands and poorer well-being, especially when caregiving is combined with paid employment. Subjective feelings of high time pressure, which include feeling rushed and short on time, relate to poorer self-reported measures of mental health more than objective task load. Attentional awareness is one of the fundamental components of mindfulness alongside nonjudgmental acceptance; it has been linked with more optimal mental health and feelings of having enough time. This cross-sectional study examined whether higher levels of perceived time pressure would relate to poorer self-reported mental health functioning and …

Survival Politics On A Working Waterfront: Rules Change Faster Than Prices In The South Texas Shrimp Fishery, Owen Temby, Anthony R. Lima

School of Earth, Environmental, & Marine Sciences Faculty Publications

In 2024–2025, the U.S. and Texas governments raced to save Gulf shrimp. Texas passed a truth-in labeling law for food service in restaurants. Federal agencies added antidumping and countervailing duty orders and new tariffs. This case follows Brownsville and Port Isabel, where dock prices slid while boats and crews aged. We frame the response as survival politics: urgent and improvised moves to keep a livelihood going even when imports set the price. Using legislative hearings, agency notices, local reporting, and port records, we show that rules reset faster than prices. Inventories, contracts, and supplier substitution delay any lift at the …

Synthesis, Characterization, And Biological Potentials Of Chalcones Derivatives, Acer Juma Hamad, Hamdia Hateem Jawad, Kadhim Abdulwahid Aadim

Theoretical Construction And Practical Transformation Of “New Science Popularization” In Process Of Chinese Modernization, Ting Wang, Haonan Du, Tian Zhu, Shihui Yang, Rongting Zhou

Bulletin of Chinese Academy of Sciences (Chinese Version)

Rooted in the historical context of China’s national strategy-driven science popularization (SP), this study analyzes the local practical integration of “science popularization” and “science and technology communication”. It proposes a theoretical framework for “new science popularization” suitable for a strong state-strong society collaborative governance environment, based on the fundamental hypotheses of “innovation-driven development”, “systemic coupling”, and “nodal creation”. The core argument introduces the “One Body, Two Wings; Three Layers, Three Stages” dynamic system model. This model elucidates how SP, under the unity of national strategy and human development, achieves a spiral evolution—from knowledge interconnection and literacy co-shaping to ecosystem co-creation—through …

Plant-Based Dietary Patterns Are Associated With Slower Epigenetic Aging, Alexis C Wood, Audrey Ting, Morgan E Grams, Bing Yu, Kelly Ruggles, James S Floyd, Dan E Arking, Casey M Rebholz

Faculty, Staff and Students Publications

Greater adherence to plant-based diets is associated with health benefits. Dietary intake can modify DNA methylation patterns, but it is unknown whether plant-based diets in a largely non-vegetarian population are associated with DNA methylation-based epigenetic aging measures. We examined the associations between 4 different types of plant-based diets indices (PDI) [overall PDI, provegetarian diet, healthy PDI, and unhealthy PDI] and epigenetic aging. We used data from the Atherosclerosis Risk in Communities (ARIC) Study (N=2,810) and National Health and Nutrition Examination Survey (NHANES, N=2,056). PDIs negatively scored higher intake of animal products and positively scored higher intake of all or selected …

Welcome To The Trump Administration’S Board Of Immigration Appeals. The Immigrant Always Loses., Jason A. Cade

Scholarly Works

The first 100 opinions in Volume 29 of the Board of Immigration Appeals’ precedential decisions—issued at more than three times the historical pace—constitute a project. The Trump Administration has used the Attorney General’s self-referral power and a reconstituted, ideologically aligned Board to engineer a body of precedents that reliably produces one result: removal. This Essay organizes these decisions, cataloged in a full Appendix, into five main categories: (1) narrowing relief for noncitizens alleging persecution; (2) expanding mandatory detention while narrowing discretionary release; (3) maximizing the immigration consequences of criminal history and related grounds while foreclosing the relief mechanisms Congress created …

Multi-Objective Optimization Of Waste Incineration For Minimal Carbon Monoxide And Sulfur Dioxide Emission And Rate Maximization: A Case Study Of Mbezi, Mkuranga-Pwani, Tanzania, Grangay M. Nyanghura, Enock W. Nshama

Tanzania Journal of Science

Incineration is widely employed for hazardous waste disposal, but results in harmful flue gas emissions. This study optimizes a double-chamber incineration process to reduce sulfur dioxide (SO2) and carbon monoxide (CO) emissions while maximizing the incineration rate. The effects of waste mass, primary chamber temperature (PT), and secondary chamber temperature (ST) were analyzed using a full factorial design of 27 experiments. ANOVA revealed that mass had the greatest impact on emissions and incineration time, ST had a moderate effect, and PT had little influence. Regression analysis provided models for incineration time, CO, and SO2 emissions. Single-objective optimization using sequential quadratic …
