Assessing Global Citizenship Pathways In A Communication, Advocacy, And Global Citizenship Classroom In The Midwest, Satveer Kaur-Gill

UNL Faculty Course Portfolios

To assess instruction in an undergraduate communication course titled Communication, Advocacy, and Global Citizenship, this qualitative inquiry examined how undergraduate students at a Midwest university engaged with global citizenship as a communicative process by conducting a content analysis of student assignments, guided by three key research questions formulated from four course objectives. The assessment found that place-based learning on global issues enhanced students' understanding of the meaning of global citizenship in a globalized world. Based on a qualitative evaluation of their key assignments, students successfully articulated threads and connections between local community concerns and issues as globally situated communicative phenomena. …

The Second Amendment Rights Of Undocumented Immigrants, Alan Mygatt-Tauber

Nebraska Law Review

In the 2008 case, District of Columbia v. Heller, the Supreme Court, for the first time, held that the Second Amendment protects an individual right to bear arms. Challenges to various federal gun control laws immediately followed, including challenges to 18 U.S.C. § 922(g)(5)(a), which prohibits possession by an undocumented immigrant. Between 2008 and 2022, courts faced with challenges to § 922(g)(5)(a) universally upheld it. Then the Court decided New York State Rifle and Pistol Association v. Bruen, in which it discarded the means-end balancing tests the courts of appeals had adopted, instead preferring a test focused on “history and …

Toward A General Legislative Presumption Of Probation In Nebraska, Velma Lockman

Nebraska Law Review

“It is curious that the Legislature has chosen to give a presumption of probation for more serious felony offenses, but not for lesser misdemeanor offenses.” With those words, Judge Bishop concluded a heart-wrenching opinion in State v. Anderson, which upheld Courtney Anderson’s sentence of 240 days in jail. Despite being sentenced for a first offense Class I misdemeanor and nearly every sentencing factor counseling in favor of probation, the district court decided to separate Ms. Anderson from her two children, one of whom was a newborn. A combination of the Nebraska Supreme Court’s highly deferential standard of review for excessive …

Protecting (Restorative) Justice: An Analysis Of Confidentiality, Admissibility And Privilege Provisions In State Law, Thalia Gonzalez, Aidan Lorraine Tomlinson

Nebraska Law Review

Over the last thirty years, the use of restorative justice within and adjacent to state juvenile and criminal proceedings, including community contexts, has expanded significantly in the United States. As such, what once could be fairly characterized by scholars as a norm and practice at the legal margins has moved widely into the mainstream. As increased legal institutionalization occurred, so too has scholarly attention. Shifting away from foundational “first generation” theoretical and empirical legal studies of practices and programs, a second stream of interdisciplinary legal scholarship has emerged centralizing structural questions as to the legalization of restorative justice. In this …

Posthumous Restorative Justice, Michael L. Moffitt

Nebraska Law Review

Restorative justice (“RJ”) processes typically envision the prospect of voluntary participation by those who suffered harm, by those who caused the harm, and often by the community or communities of people who surround them. When one or more of these potential participants opts not to participate, RJ processes often adapt to provide as many of the restorative benefits as possible to those who do choose to participate. This Article asks what, if any, adaptations of RJ processes may be appropriate in contexts in which some or all of the people listed above cannot participate, because they are now dead.

Restorative Reparatory Justice, Inga N. Laurent

Nebraska Law Review

As global calls for reparatory justice—aimed at addressing “historical” and ongoing harms stemming from genocide, dispossession, assimilation, and enslavement—grow, this Article explores critical challenges in designing transformative processes of reparation. While a host of transitional justice mechanisms, such as reparations, tribunals, and truth and reconciliation processes are at the forefront of these discussions, a critical examination of their limitations will provide the groundwork for their enhancement. Past applications of transitional justice mechanisms have frequently failed to address root causes of violence, which reinforces State power despite its failures to protect its citizens from that violence, causing secondary harm to survivors/victims.

North Korean Archaeology And Archaeological Interpretation In The Twentieth Century, Gabrielle E. Stoddard

Nebraska Anthropologist

This paper examines how political unrest in North Korea during the twentieth century affected Korean Archaeology. During the occupation of the Korean peninsula by the Empire of Japan during 1910–1945, Japanese scholars embarked on the study of archaeology in Korea. Japanese archaeologists used Korean archaeological data and materials to push a colonial viewpoint that Korea was a weak state that could not advance without oversight from a conquering nation. After Korea was liberated by the Soviet Union and the United States in 1945, it was divided into the Democratic People’s Republic of Korea (North) and the Republic of Korea (South). …

From Prometheus To Pygmalion To Pandora: Teaching Greek Mythology With Frankenstein’S “Dark Brides”, Kyle William Bishop

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

As Mary Shelley unambiguously informs readers on the title page of her 1818 novel Frankenstein, her tale of Victor’s discovery of the secret of non-biological reproduction represents the Promethean myth, a morality tale warning against the usurpation of divine authority. In Shelley’s novel, Victor ultimately recognizes the dangerous path he has discovered, and he refuses to create a female companion for his hideous progeny, risking his own life to protect the world from a potential race of monsters. In the cinematic tradition, however, this unrealized “bride” often has been created, and these fantastic narratives realize the Pygmalion myth, that …

Pymelt-Px: A Python Script For Modeling Melting Of A Pyroxenite-Peridotite Bilithological Mantle, Ana L. Jimenez Bustos

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The study of oceanic crust formation is a fundamental building block in our understanding of the processes of planetary formation, necessitating an understanding of the melt generation processes that help form oceanic crust. To aid in this purpose, we present pyMeltPX: a bilithological pyroxenite-peridotite mantle modeling script. Although the mantle is primarily comprised of peridotite, pyroxenite is a minor but ubiquitous feature of the mantle and can contribute a disproportionate amount of melt to crustal generation in mid-ocean ridge and ocean island basalt settings. Our model, pyMeltPX, is a python coded, extensible tool based on the Excel calculator by Lambart …

A Temporal Extension Of Tasselnet With Uncertainty Quantification Using Bayesian Latent Autoregressive Model, Gayara Demini Fernando Muthunama Gonnage

Current studies in this area predominantly focus on training object detection algorithms to enhance prediction accuracy and efficiency. Images for this task are often captured in sequences, meaning they capture the exact location of the maize fields over time. However, existing tassel detection and counting methods typically ignore this sequential nature, …

Early Childhood Educators' Perception Of Burnout: Impact On Educator Self-Efficacy, Teacher-Child Relationships, And Children's Emotional Regulation, Isaac M.D. Bowman

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Early childhood educators (ECE) play a critical role in the academic advancement and nurturing care provided to children in their care, a distinct difference in role and responsibilities compared to traditional K-12 schooling. Published by the Buffett Early Childhood Institute, a report pertaining to ECE turnover revealed a nearly 40% annual turnover rate. Factors ECEs previously attributed to their exit of the early childhood education field involve low wage, low self-efficacy, and dealing with challenging behaviors. While not an exhaustive list, in a field relying predominantly on routine and consistency, ECE turnover rate highlights a necessity in exploring potential indirect …

Assessing The Language And Reading Abilities Of Students With Mosaic Down Syndrome, Emma G. Conradi

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Language and reading are important skills for academic and social success, yet individuals with Down syndrome often face significant challenges developing these skills (Abbeduto et al., 2007; Martin et al., 2009). However, almost all the available research on the language and reading abilities of individuals with Down syndrome comes from research focused on individuals with Full Trisomy 21. To date, there has been virtually no research specifically examining the language and reading skills of individuals with mosaic Down syndrome (Buckley & Bird, 2002), a rare karyotype of Down syndrome. Therefore, the purpose of this study is to describe the language …

Investigating Molecular Rotation And Vibration With Ultrafast Electron Diffraction, Haoran Zhao

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ultrafast electron diffraction (UED) has emerged since the late 20th century as a powerful technique for resolving molecular dynamics. With its high spatial and temporal resolution, UED can now measure rotational motion induced by linearly polarized, nonresonant, nonadiabatic laser pulses—one of the fundamental molecular degrees of freedom with broad applications. By combining laser-induced alignment with UED, new capabilities such as three-dimensional structural retrieval and isotope detection have been demonstrated, as discussed in Chapter 2.

In Chapter 3, three symmetry relations in the coefficients of rotational wave packets are identified and derived, reducing the computational cost of simulating asymmetric-top molecular alignment …

Global, Continental, And Local Scale Paleoenvironmental Reconstruction Methods For Interpreting The History Of Miocene North America And The Great Plains, Willow Hue Nguy

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The Miocene of North America is characterized by dynamic changes in herbivore communities, habitat composition, and global climate. Long-term cooling and drying trends influenced large changes in floral and faunal communities. The Great Plains, North America shifted from closed-canopy biomes to open-canopy biomes with C3-grasses to biomes with C4-grasses. This shift affected the herbivore communities as browsing-adapted ungulates were replaced by grazing-adapted ungulates. Much focus has centered on the Great Plains, so it is not well understood how the changes in biomes compare to other regions of North America. The models used for vegetation density indicate open-canopy biomes since at …

Residential Hvac Installation Faults: Field Prevalence, Drivers, And Energy Impacts, Seyed Ali Rooholghodos

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Faults in residential comfort systems can have detrimental effects on the performance of the system, reducing the energy efficiency, affecting indoor comfort, and shortening equipment lifespan. Many of the faults occur at installation. However, there has not previously been a systematic and nationally representative study to indicate the prevalence of the faults, meaning the distribution of faults by fault type and fault intensity. Understanding true fault prevalence is essential to be able to identify derivers, and to assess the incremental electricity consumption of the new installation systems.

This study presents on-site data from 341 new central cooling systems—air conditioners and …

Detecting Prescribed Fire, Haying And Grazing Events Via Remote Sensing To Create Grassland Disturbance Landcovers For The Ring-Necked Pheasant (Phasianus Colchicus), Megan A. Baldissara

School of Natural Resources: Dissertations, Theses, and Student Research

This dissertation developed disturbance detection models to fulfill the need for remote sensing landcover products describing grassland structure. The use of landcover products derived from remote sensing is increasing over time in pheasant (Phasianus colchicus) research. Such landcover, however, does not provide relevant pheasant structural habitat information (Chapter 1). Pheasants require tall, high-density grassland for nesting, tall grassland with medium density for brood rearing, and tall grassland for wintering. Time since disturbance can serve as a proxy for structure, as it shapes vegetation by removing biomass and resetting succession. Disturbance is easier to detect than structure with current …

On Bayesian Empirical Likelihood-Based Method For Complex Survey Data With Application To Non-Probability Sampling, Md Hasibur Rahman

Department of Statistics: Dissertations, Theses, and Student Research

This thesis develops a Bayesian empirical likelihood (BEL) framework for inference under complex survey designs and extends it to non-probability sampling. Parametric likelihood based methods are difficult to apply to complex survey data because the likelihood is rarely available in closed form. EL provides a flexible alternative by replacing the parametric likelihood with an empirical likelihood constructed from moment conditions. The proposed method first integrates empirical likelihood constraints with survey design features then extends BEL to non-probability sampling through selection models and design consistent restrictions. Posterior inference is carried out using a Metropolis–Hastings MCMC algorithm. A real-data analysis further illustrates …

The Urban Heat Island And Its Role In Shaping Convective Environments: An Observational Study, Benjamin W. Moll

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The continued spread of urbanization and its well-documented effects on regional weather and climate necessitate further research. Urban environments are often warmer and drier than their rural surroundings. This trade-off between a warmer but drier environment could have a complex impact on deep convection and its initiation. Previous studies have noted significant changes in precipitation patterns around cities as well as changes to ongoing deep convection. Given the well-documented theory and past research, it is hypothesized here that urban areas have a significant impact on the PBL thermodynamics of convective environments. The urban heat island (UHI) component of the Micro …

Llm-Assisted Cwe Identification, Severity Assessment, And Vulnerability Description Generation, Mohammad Jalili Torkamani

School of Computing: Dissertations, Theses, and Student Research

Identifying the underlying weakness types and assessing their severity using CWE and CVSS standards are critical steps in software vulnerability management. While timely assessment of vulnerabilities mitigates the impact of severe security incidents, automating joint CWE identification and severity assessment remains challenging due to the heterogeneity of vulnerabilities across different code granularities and programming languages. In addition, generating vulnerability descriptions is often time-consuming, as it requires extensive manual review, validation, and writing by security experts.

In this thesis, we leverage the capabilities of Large Language Models (LLMs) to automate the identification of CWE identifiers and the assessment of their severity …

Realism, Truth, And Commitment: An Exposition And Critique Of Michael Devitt's Constitutive Account Of Realism, Samuel Elias Hobbs

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Michael Devitt argues in Realism and Truth that positive semantic issues are not constitutive of realism concerning the mostly impersonal external world. This is motivated by his second maxim which prescribes that the metaphysical (ontological) issue of realism is to be (sharply) distinguished from any (positive) semantic issue. Devitt’s argument is that his view of realism, entitled ‘Realism’, doesn’t entail and isn’t entailed by any doctrine of truth.

This dissertation presents a critique of the argument indicated above and, thereby, Devitt’s second maxim. I present Devitt’s account of Realism and his overview of theories of truth. I next present Devitt’s …

Evaluation Of Distractor Model Specifications On Assessment Quality Within The Framework Of Assessment Engineering, Sunhyoung Lee

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Responding to the high demand for new test items, model-based item development has emerged as a promising approach for efficient item creation. Item models within Assessment Engineering (AE) offer a systematic framework that effectively generates a large volume of new items. In the development of multiple-choice questions, well-constructed distractors are essential for ensuring item quality, although creating them requires significant time and resources. A distractor model is a sub-model within an item model, producing correct answers and distractors aligned with all potential items to be generated. Various types of distractor models have different characteristics and offer efficient methods for generating …

Reinforcement Learning Based Security Schemes For Distributed Ai Systems, Ashan Chamath Gunawardena

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Distributed machine learning (DML) is a component of modern intelligent systems, enabling collaborative training across devices such as mobile clients, vehicles, and edge networks. However, the decentralized nature of these systems introduces vulnerabilities, particularly data poisoning attacks that compromise model integrity and degrade performance. Traditional defenses, such as statistical filtering, robust aggregation, and privacy-preserving techniques, often struggle to adapt to overwhelming adversaries or operate under strict privacy and real-time constraints. This dissertation proposes the use of reinforcement learning (RL) and deep reinforcement learning (DRL) based misbehavior detection schemes that dynamically identify poisoning attempts in distributed AI systems, including federated learning, …
