A Crust Of Bread: Religious Resistance And The Fourteenth Amendment, Kurt T. Lash, Stephanie Hall Barclay Jan 2025

A Crust Of Bread: Religious Resistance And The Fourteenth Amendment, Kurt T. Lash, Stephanie Hall Barclay

Law Faculty Publications

In Employment Division v. Smith, the U.S. Supreme Court denied heightened constitutional protection to religiously motivated exercise burdened by neutral and generally applicable laws. The history presented in this Article suggests that the Smith approach conflicts with the original understanding of the Fourteenth Amendment. Out of the crucible of religious abolitionist resistance to the Fugitive Slave Act emerged a substantive theory of constitutional religious freedom: American citizens should have the right to obey the Biblical command to care for the needy and provide the hungry a "crust of bread," even if doing so was contrary to neutral and generally …


Secrets Of The Killing State: The Medical Professional Mandate, Corinna Barrett Lain Jan 2025

Secrets Of The Killing State: The Medical Professional Mandate, Corinna Barrett Lain

Law Faculty Publications

When New Jersey reinstated the death penalty in 1983, the state hadn’t conducted an execution in twenty years, so no one knew how to conduct an execution by lethal injection. Doctors at the state prison refused to participate, citing medical ethics that required them to “support life, not end it,” and that left prison officials thinking that they might have to conduct the executions themselves. “That is not an easy task for an amateur,” a reporter covering the quandary wrote. Unsure of what else do to, officials called upon Fred Leuchter, an engineer who had worked with a number of …

Attention's Loop: A Sculptor's Reverie On The Coexistence Of Substance And Spirit, Elizabeth King, Katherine Wetzel Jan 2025

Attention's Loop: A Sculptor's Reverie On The Coexistence Of Substance And Spirit, Elizabeth King, Katherine Wetzel

Attention's Loop

This is a book about attention and memory. I am a sculptor, so it is also a book about size, dirt, artifice, work, and eye. The text is a set of stories and interruptions that pile up to make a play of overlapping loops. My organizing principle is the image of the round-trip, so one may open the book and step into it at any point. Most of Katherine Wetzel’s photographs are of a single sculpture. It is a self-portrait, a particular kind of round-trip, and it is small: one-half life-size. Called Pupil, it is jointed and movable, and …


The Masterplot Of The Market, Allison Anna Tait, Luke Norris Jan 2025

The Masterplot Of The Market, Allison Anna Tait, Luke Norris

Law Faculty Publications

Stories about the family, work, and the market circulate in law, legal discourse, and beyond. The family, we are told by numerous authorities, is a non-market site, centred on emotional attachment rather than economic transaction. It is a site of interpersonal care, growth, and nurturance that acts as a counter to the excesses of an unbridled marketplace. The market, in contrast, is a site where autonomous beings contract, pursuing their interests efficiently and maximising wealth. This is one masterplot of the market, which, as it operates in the United States, constructs certain household members outside of the market and constructs …

A Bounded Custom Gpt Structures Operational Knowledge For Small-Industry Decision Support, Ikhwan Arief, Alizar Hasan, Nilda Tri Putri, Hafiz Rahmann

Knowledge Engineering and Data Science

Small manufacturing and craft-based firms increasingly use Generative Artificial Intelligence (GenAI) through public chat interfaces, low-cost tools, and informal experimentation. However, these firms often make operational decisions with incomplete records, tacit owner knowledge, fragmented spreadsheets, and limited managerial capacity. Under such conditions, open-ended chatbots may generate fluent but unsafe recommendations by overlooking missing information, contradictory evidence, feasibility constraints, and implementation constraints. This study presents Asisten Cerdas Industri Kecil as a bounded Custom GPT artifact for operational diagnosis, priority selection, and short-horizon action planning in small industries. Using a Design Science Research approach, the study develops a documented artifact corpus comprising …


Simulations Of Electron Detection Systematic Errors For A Ucna+ Experiment, Rashika Gupta Jan 2025

Simulations Of Electron Detection Systematic Errors For A Ucna+ Experiment, Rashika Gupta

Theses and Dissertations--Physics and Astronomy

The Ultracold Neutron Asymmetry+ (UCNA+) experiment at the Los Alamos Neu- tron Science Center (LANSCE) Ultracold Neutron source is an upgrade of the UCNA experiment, designed to measure the neutron beta decay asymmetry parameter, A 0 , with a precision of less than 0.2% using polarized ultracold neutrons (UCN). Neutron beta decay is governed by the weak interaction, and a precise measurement of A 0 provides a determination of the axial-vector to vector coupling ratio, λ = gA /gV . When combined with a measurement of the neutron lifetime, this allows the extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element Vud …

Optimizing External Radioactive Calibration Source Strength To Maximize The Livetime Of The Nexo Detector, Thakur P. Bhatta

Theses and Dissertations--Physics and Astronomy

The proposed next Enriched Xenon Observatory (nEXO) experiment aims to detect neutrinoless double beta decay in 136Xe, a rare process with profound implications for particle physics and our understanding of the neutrino. Achieving the required sensitivity demands ultra-low background conditions, making both material radiop urity screening and precise detector calibration essential. This dissertation addresses two key calibration challenges in preparation for nEXO. First, I investigated discrepancies in calibration efficiency measurements of the high-purity germanium (HPGe) detector named as GeIV located 4850 feet under ground at the Sanford Underground Research Facility, Lead, SD. The root cause for the discrepancy was found …


Precision Measurement Of The Muon’ S Anomalous Precession Frequency Using Energy Integrated Analysis In The Fermilab Muon G- 2 Experiment, Joseph Peck Jan 2025

Precision Measurement Of The Muon’ S Anomalous Precession Frequency Using Energy Integrated Analysis In The Fermilab Muon G- 2 Experiment, Joseph Peck

Theses and Dissertations--Physics and Astronomy

This dissertation investigates the anomalous magnetic moment of the muon, aµ, through the Fermilab Muon g -2 Experiment, which aims to measure aµ to a precision of about 140 parts-per-billion.

Muons were injected into a magnetic storage ring where their decay positrons were detected by calorimeters. The changing spin and momentum orientation leads to an oscillation in decay positron counts, known as the anomalous precession frequency ! a. Using the magnetic field and !a measurements, we can determine the value of a µ. This study focuses on the Q-Method determination of !a, which utilizes an energyintegrated reconstruction rather than high-energy …

Structural And Physical Properties Of Solid State Materials: Cegage, Cssni3, And Yb2Si2-XGeXAl, Liam J. Scanlon

Theses and Dissertations--Physics and Astronomy

We present studies of three independent solid state materials: CeGaGe, CsSnI3, and Yb2Si2-xGexAl.

CeGaGe is a magnetic candidate Weyl semimetal. Magnetic Weyl semimetals have possible technological applications due to their electronically conducting bulk states, magnetic states, and topologically protected surface states. We grew single crystals of CeGaGe using the zone-refinement method and flux-growth method. With single crystal X-ray and neutron diffraction, we found that zone-refined CeGaGe crystallizes with the I41md symmetry (space group 109). With single crystal X-ray diffraction, we found that flux-grown samples of CeGaGe have the …

Cognitive Biases In Online Opinion Platforms: A Review And Mapping, Rudolph T. Bedeley

Funded Scholarship

Raising users’ awareness about cognitive biases in online platforms can result in better decisions. However, despite scholarly efforts to examine cognitive biases, there is still a lack of research that systematically analyzes, summarizes, and categorizes the current state of online cognitive biases. To this end, we conducted this systematic review by synthesizing the extant literature to reveal the current state of research on the prevalence and influence of online cognitive biases in the IS discipline. We described the mechanisms of the common cognitive biases, showed how they are studied, and mapped such biases in a six-level information processing model. Our …


Pedagogical Idealism, Race, And The Specter Of Africa In Josefina Aldecoa’S Historia De Una Maestra And Donato Ndongo’S Las Tinieblas De Tu Memoria Negra, Parker Lawson Jan 2025

Pedagogical Idealism, Race, And The Specter Of Africa In Josefina Aldecoa’S Historia De Una Maestra And Donato Ndongo’S Las Tinieblas De Tu Memoria Negra, Parker Lawson

Funded Scholarship

This article examines two contemporary Spanish novels, Josefina Aldecoa’s Historia de una maestra (1990) and Donato Ndongo’s Las tinieblas de tu memoria negra (1987), to assess the status of pedagogical idealism and experimentation with particular attention to Equatorial Guinea. Where previous scholarly attention to Aldecoa’s novel focuses on the protagonist’s credentials as a progressive pedagogue, this article draws attention to Gabriela’s etapa guineana to argue that the text cripples under the weight of postcolonial analysis as regards race, religion, class, and language. Drawing the novel into comparison with Ndongo’s text, the article argues that Spanish colonial pedagogy flattened, or sought …

Wondrous Uncertainty: Transforming Student Educational Experiences Using Restorative Practices, Zachary C. Schafer Jan 2025

Wondrous Uncertainty: Transforming Student Educational Experiences Using Restorative Practices, Zachary C. Schafer

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

One of the primary purposes of education is to help students make sense of their lived experiences. In the process of becoming, students navigate multiple relationships (school, peers, adults, and with self). These relationships often cause conditions of uncertainty which can be managed and transformed using restorative practices in tandem with the academic disciplines taught in school. Over the last decade this has been my inquiry puzzle, “As educators, how can we embrace uncertainty with students as a way of helping to empower them through their dignity, with the academic disciplines as a lens through which relational learning occurs in …

Analyzing Reciprocating Piston Expander Performance In Small-Scale Caes Considering Expansion Mismatch And Residual Mass Losses, Mehrdad Poursadegh

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

Energy storage (ES) has become an essential element of modern energy systems, particularly with the rapid growth of renewable energy sources. While these sources are central to global decarbonization efforts, their intermittent nature creates significant challenges for both grid operators and end users. To address these challenges, a wide range of storage technologies have been developed ranging from large utility-scale to small behind-the-meter units. Among these, Compressed Air Energy Storage (CAES) stands out for its long lifespan, low storage cost per unit of energy, and ability to provide both electricity and thermal energy. However, small- and micro-scale CAES systems, unlike …

In Kenya, climate variability and change threaten smallholder, rainfed farms, with crop failures, yield reductions, and pest infestations. Efficient agroecological strategies, such as Push-Pull intercropping, offer documented benefits including pest control, improved soil fertility, and water conservation compared to traditional maize monocropping. To date, no studies exist comparing traditional maize monocropping and Push-Pull intercropping using earth observation tools over several growing seasons in East Africa. Our research addresses this by harmonizing Landsat 7, 8, 9 with Sentinel-2 remote sensing time series from 2016 to 2023. Phenological metrics of 15 growing seasons are extracted based on a threshold method using the …

Introduction: Fetal alcohol spectrum disorder (FASD) is the leading preventable cause of pediatric cognitive disability and is associated with dysmyelination. We examined possible clinical co-determinants that might interact with EtOH in impairing oligodendrocyte (OL) development. Women who drink, including pregnant women, also disproportionately suffer from depression (mDepression), which we have shown is a risk factor for FASD. Might depression during pregnancy contribute to OL pathology? Maternal obesity (mObesity) also inhibits white matter development in fetal brain. Finally, tobacco exposure inhibits not only OL development, but also the production of structural proteins, such as actin. Our human biobank derived from voluntarily …


Violence And Taoist Ethics In Ursula K. Le Guin’S The Word For World Is Forest, Aleena Achamma Paul, Swathi Krishna S Jan 2025

Violence And Taoist Ethics In Ursula K. Le Guin’S The Word For World Is Forest, Aleena Achamma Paul, Swathi Krishna S

UKL: The Journal of Ursula K. Le Guin Studies

This note critically investigates the ethico-moral intricacies of violence/peace in Ursula K. Le Guin’s The Word for World is Forest (1976) while arguing that her radical political sensibilities are informed by her ardent Taoist worldview. Amidst the urgent tussle for domination by the colonizing Terrans and the struggle for survival by the native Athsheans in the fictional planet Athshe, Le Guin incorporates her incisive critique of imperialist exploitation and militarism while upholding the non-dualistic ethics of Taoism. Moving beyond the moral imperatives and either/or debates, Le Guin illustrates how from time-to-time violence turns to be the singular means of self-preservation …
