The Presentation And Impact Of Compassion Fatigue And Compassion Satisfaction In Occupational And Physical Therapists Working With People Who Have Sustained Burn Injuries, Miranda L. Yelvington

Theses and Dissertations

Therapists who work with burn survivors are frequently exposed to patients who are undergoing or have undergone severe trauma and pain. This exposure places burn therapists at risk for the development of compassion fatigue and diminished professional quality of life. Alternatively, the sense of purpose and altruism experienced by these same therapists have the potential to foster compassion satisfaction. This dissertation explores the prevalence and presentation of compassion fatigue and compassion satisfaction in burn therapists in the United States. This three-paper design focuses on: 1) a scoping review of current literature, 2) a cross-sectional quantitative survey utilizing the Professional Quality …

U.S. Travelers’ Perceived Image Of Latin America As Their Future Travel Destination, Maricela I. Montes-Guerra, Natalia Zapata-Cuervo, Miyoung Jeong

Faculty Publications

This study identified U.S. travelers’ perceptions toward Latin America as their future place to visit, based on their perceived destination attributes, activities, and overall affective image. Selecting nine attractive destinations, this study aimed, first, to develop U.S. travelers’ perceptual mapping of countries by using destination image attributes and activities, second, to determine comparative strengths and weaknesses, and third, to propose destination marketing strategies that will derive U.S. travelers' attention to the country. Overall, Americans have favorable affective image toward the nine tourism destinations in Latin America. Costa Rica was respondents’ most preferred country to visit, followed by Peru and Brazil.

Preparing Students For Life After College: A Mixed-Methods Analysis, Nichole Zumbach Harken

Dissertations and Theses @ UNI

Institutions of higher education work to engage students in high-impact practices throughout their educational journey. Although prior research highlights the increase of stress as students near graduation, little research has explored how students manage the transition out of higher education. The purpose of this study was to investigate graduating students’ concerns, the emotional impact of those concerns, the discovery of information related to adulting practices, and the potential impact of a curriculum-infused exit program. The data were collected at a Midwest, comprehensive, liberal arts institution that confers bachelor, master’s, and doctoral degrees. To develop better praxis, the authentic union of …

Stakeholder Impact On Individual Development Within A Transition Worksite Program: A Case Study, Kong Chen

Dissertations and Theses @ UNI

Emerging adults (Arnett, 2000) struggled with their transition from school to employment (Arnett, 2015). Within that group, individuals with disabilities were in a particularly vulnerable and disadvantaged situation. The 2009 to 2019 employment rates for emerging adults with disabilities (33-39%) were far lower than for those without disabilities (73-79%; U.S. Census, 2019). There are employment programs designed to assist and support individuals with disabilities to transition to and retain employment. One such program, Project SEARCH, has served over 34,000 young adults with intellectual disabilities while achieving an average 72% employment rate when program participants had completed the training. Several studies …

Msdrp: A Deep Learning Model Based On Multisource Data For Predicting Drug Response, Haochen Zhao, Xiaoyu Zhang, Qichang Zhao, Yaohang Li, Jianxin Wang

Computer Science Faculty Publications

Motivation: Cancer heterogeneity drastically affects cancer therapeutic outcomes. Predicting drug response in vitro is expected to help formulate personalized therapy regimens. In recent years, several computational models based on machine learning and deep learning have been proposed to predict drug response in vitro. However, most of these methods capture drug features based on a single drug description (e.g. drug structure), without considering the relationships between drugs and biological entities (e.g. target, diseases, and side effects). Moreover, most of these methods collect features separately for drugs and cell lines but fail to consider the pairwise interactions between drugs and cell …

Claimdistiller: Scientific Claim Extraction With Supervised Contrastive Learning, Xin Wei, Md Reshad Ul Hoque, Jian Wu, Jiang Li

Computer Science Faculty Publications

The growth of scientific papers in the past decades calls for effective claim extraction tools to automatically and accurately locate key claims from unstructured text. Such claims will benefit content-wise aggregated exploration of scientific knowledge beyond the metadata level. One challenge of building such a model is how to effectively use limited labeled training data. In this paper, we compared transfer learning and contrastive learning frameworks in terms of performance, time and training data size. We found contrastive learning has better performance at a lower cost of data across all models. Our contrastive-learning-based model ClaimDistiller has the highest performance, boosting …

A Single-Cell Atlas Of Bovine Skeletal Muscle Reveals Mechanisms Regulating Intramuscular Adipogenesis And Fibrogenesis, Leshan Wang, Peidong Gao, Chaoyag Li, Qianglin Liu, Zeyang Yao, Yuxia Li, Xujia Zhang, Jiangwen Sun, Constantine Simintiras, Matthew Welborn, Kenneth Mcmillin, Stephanie Oprescu, Shihuan Kuang, Xing Fu

Computer Science Faculty Publications

Background: Intramuscular fat (IMF) and intramuscular connective tissue (IMC) are often seen in human myopathies and are central to beef quality. The mechanisms regulating their accumulation remain poorly understood. Here, we explored the possibility of using beef cattle as a novel model for mechanistic studies of intramuscular adipogenesis and fibrogenesis.

Methods: Skeletal muscle single-cell RNAseq was performed on three cattle breeds, including Wagyu (high IMF), Brahman (abundant IMC but scarce IMF), and Wagyu/Brahman cross. Sophisticated bioinformatics analyses, including clustering analysis, gene set enrichment analyses, gene regulatory network construction, RNA velocity, pseudotime analysis, and cell-cell communication analysis, were performed to elucidate …

Comparison Of Physics-Based Deformable Registration Methods For Image-Guided Neurosurgery, Nikos Chrisochoides, Yixun Liu, Fotis Drakopoulos, Andriy Kot, Panos Foteinos, Christos Tsolakis, Emmanuel Billias, Olivier Clatz, Nicholas Ayache, Andrey Fedorov, Alex Golby, Peter Black, Ron Kikinis

Computer Science Faculty Publications

This paper compares three finite element-based methods used in a physics-based non-rigid registration approach and reports on the progress made over the last 15 years. Large brain shifts caused by brain tumor removal affect registration accuracy by creating point and element outliers. A combination of approximation- and geometry-based point and element outlier rejection improves the rigid registration error by 2.5 mm and meets the real-time constraints (4 min). In addition, the paper raises several questions and presents two open problems for the robust estimation and improvement of registration error in the presence of outliers due to sparse, noisy, and incomplete …

A Structure-Aware Generative Adversarial Network For Bilingual Lexicon Induction, Bocheng Han, Qian Tao, Lusi Li, Zhihao Xiong

Computer Science Faculty Publications

Bilingual lexicon induction (BLI) is the task of inducing word translations with a learned mapping function that aligns monolingual word embedding spaces in two different languages. However, most previous methods treat word embeddings as isolated entities and fail to jointly consider both the intra-space and inter-space topological relations between words. This limitation makes it challenging to align words from embedding spaces with distinct topological structures, especially when the assumption of isomorphism may not hold. To this end, we propose a novel approach called the Structure-Aware Generative Adversarial Network (SA-GAN) model to explicitly capture multiple topological structure information to achieve accurate …

Identifying The Serious Clinical Outcomes Of Adverse Reactions To Drugs By A Multi-Task Deep Learning Framework, Haochen Zhao, Peng Ni, Qichang Zhao, Xiao Liang, Di Ai, Shannon Erhardt, Jun Wang, Yaohang Li, Jiianxin Wang

Computer Science Faculty Publications

Adverse Drug Reactions (ADRs) have a direct impact on human health. As continuous pharmacovigilance and drug monitoring prove to be costly and time-consuming, computational methods have emerged as promising alternatives. However, most existing computational methods primarily focus on predicting whether or not the drug is associated with an adverse reaction and do not consider the core issue of drug benefit-risk assessment-whether the treatment outcome is serious when adverse drug reactions occur. To this end, we categorize serious clinical outcomes caused by adverse reactions to drugs into seven distinct classes and present a deep learning framework, so-called GCAP, for predicting the …

Using Geospatial Social Media Data For Infectious Disease Studies: A Systematic Review, Fengrui Jing, Zhenlong Li, Shan Qiao Ph.D., Jiajia Zhang Ph.D., Bankole Olatosi Ph.D., Xiaoming Li Ph.D.

Faculty Publications

Geospatial social media (GSM) data has been increasingly used in public health due to its rich, timely, and accessible spatial information, particularly in infectious disease research. This review synthesized 86 research articles that use GSM data in infectious diseases published between December 2013 and March 2022. These articles cover 12 infectious disease types ranging from respiratory infectious diseases to sexually transmitted diseases with spatial levels varying from the neighborhood, county, state, and country. We categorized these studies into three major infectious disease research domains: surveillance, explanation, and prediction. With the assistance of advanced computing, statistical and spatial methods, GSM data …

Eschatological Consumption Of Leviathan And Behemoth As Revelation Of The Messianic Torah, Andrei Orlov

Theology Faculty Research and Publications

The notion that the righteous would one day feast on Behemoth and Leviathan occupied a prominent place in early Jewish pseudepigraphical accounts, including testimonies found in the Book of the Similitudes, 4 Ezra, and 2 Baruch. Thus, from 1 Enoch 60:24 one learns that “two monsters, prepared according to the greatness of the Lord, will provide food for the chosen and righteous.”

Black Mothers’ Mothering Experiences: Race, Gender And Imprisonment, Ada Gamez

Theses & ETDs

In this study I examine the unique challenges faced by incarcerated Black mothers within the criminal justice system and how their race and gender contribute to the difficulties they face when returning to freedom. I pay particular attention to the way motherhood impacts Black mothers during and post incarceration. This study employs a combination of statistical data and content analysis. Statistical data provides a generalized view of the conditions of incarceration for Black women. Through content analysis of first-hand accounts of 4 incarcerated Black mothers I share in depth insight into how their lived experiences have impacted them in different …

A Scientific Approach To Tech Accountability, David Choffnes, Woodrow Hartzog, Scott Jordan, Athina Markopoulou, Zubair Shafiq

Faculty Scholarship

The Federal Trade Commission can only do so much to hold tech companies accountable. Enforcement agencies and the people they protect need help. One problem is that the inner workings of large organizations and complex algorithmically driven systems remain obscure and opaque while their privacy representations are voluminous and vague. In this Essay, we propose a scientific approach to tech accountability, where academic researchers can play a larger role in privacy policy. This approach involves surfacing a company’s privacy representations and statements, as well as measuring the actual behavior of their systems with respect to algorithms, user interfaces, and data …

Abandoning Animus, Robert L. Tsai

Faculty Scholarship

This Essay presents a preliminary set of arguments against the legal concept of animus grounded in actual practice. After considering the major reasons advanced in support of the animus approach as well as the main objections, I argue that the end of animus may come once we confront the limits of judicial capacity. First, judges have not been willing or able to resort to the animus rationale to call out bigotry where the evidence of hostility is robust. These failures suggest that projects founded upon judicial review to reduce hateful motivations may be overly optimistic. Second, on the occasions the …

Law And Culture, Tamar Frankel, Tomasz Braun

Faculty Scholarship

We often speak of law and culture in one breath. That may be so because both systems impose on each person and organization required rules of behavior. Yet, law and culture are quite different, though they relate to and affect each other. Therefore, it is desirable to examine their similarities and differences and their relationship. While the structures of law and culture are more similar than we might expect, their differences greatly affect the enforcement of the rules issued under each.

To be sure, both systems consist of rules and their enforcement. Most of our thoughts and knowledge, and many …

Un-Erasing Race In A Medical-Legal Partnership: Antiracist Health Justice Advocacy By Design, Danielle Pelfrey Duryea, Peggy Maisel, Kelley Saia

Faculty Scholarship

This Article covers a potential response to a Massachusetts state law which has been interpreted to require health care providers and birthing hospitals to report to state authorities any infant born to a person taking medication of opioid use disorder. While the statute mandates reports where a professional has "reasonable cause to believe that a child is suffering physical or emotional injury" as a result of substance dependence at birth, the Article highlights that many institutions report all infants born to persons with substance abuse disorders, regardless of risk of harm, for fear of penalty for failure to report. As …

Household Intimacy And Being Unmarried: Family Pluralism In The Novels Of Anthony Trollope, Linda C. Mcclain, Allison Anna Tait

Faculty Scholarship

Many critics rightfully claim that the marriage market and an inquiry into its innermost workings are at the heart of Anthony Trollope’s novels, but this Article argues that his novels also depict—on the periphery or sometimes just hiding in plain sight—a set of curiously nonmarital households. These households vary in form, but include widows and widowers living on their own, mothers and daughters living collectively, and male cousins sharing space and the work of daily living. Critics have debated whether Trollope was simply a realistic social historian—chronicling families as he found them— or whether he constructively used literary license to …

Feminist Legal Theory And Praxis After Dobbs: Science, Politics, And Expertise, Aziza Ahmed

Faculty Scholarship

Fifty years ago, in Roe v. Wade, Justice Blackmun set into motion the idea that abortion should be a decision between a woman and her doctor.' That idea traveled from the Supreme Court decision to popular discourse; with it, came the notion that when it comes to reproduction, medical experts are a key part of women's liberation. In Dobbs v. Jackson Women's Health Organization, the court ignored the role of experts and threw the question of who should decide when and how a person has an abortion to the people. In my essay for this symposium issue dedicated to feminist …

Biden V. Nebraska: The New State Standing And The (Old) Purposive Major Questions Doctrine, Jed Handelsman Shugerman

Faculty Scholarship

Chief Justice Roberts’s majority opinion in Biden v. Nebraska does not sufficiently explain how Missouri has standing under established Article III doctrine, nor how the Court approaches the major questions doctrine as a method of statutory interpretation. Clarification can come from other opinions, even other cases entirely, in which Justice’s counterarguments are suggestive of the real arguments underlying the decisions.

MOHELA may have faced a concrete injury from the student debt waiver, but there was no evidence that Missouri would – and the majority had no answer for how Missouri had standing without an injury. A debate over special state …

How Do Prosecutors "Send A Message"?, Steven Arrigg Koh

Faculty Scholarship

The recent indictments of former President Trump are stirring national debate about their effects on American society. Commentators speculate on the cases’ impact outside of the courtroom — on the 2024 election, on political polarization, and on the future of American democracy. Such cases originated in the prosecutor’s office, begging the question of if, when, and how prosecutors should consider the societal effects of the cases they bring.

Indeed, prosecutors often publicly claim that they “send a message” when they indict a defendant. What, exactly, does this mean? Often, their assumption is that such messaging goes in one direction: indictment …

Affirmative Action After Sffa, Jonathan Feingold

Faculty Scholarship

In SFFA v. Harvard (SFFA), the Supreme Court further restricted a university’s right to consider the racial identity of individual applicants during admissions. The ruling has spawned considerable confusion regarding a university’s ongoing ability to pursue racial diversity, racial inclusion, and other equality-oriented goals—whether through “raceconscious” or “race-neutral” means. To assist institutions attempting to navigate the ruling, this article outlines a set of key legal rights and responsibilities that universities continue to possess following SFFA.

Androic, W. Armstrong, J. Arrington, D. Asaturyan, K. Assumin-Gyimah, C. Ayerbe Gayoso, A. Bandari, J. Zhang, Et Al., Hall C. Collaboration

Physics Faculty Publications

The nuclear dependence of the inclusive inelastic electron scattering cross section (the EMC effect) has been measured for the first time in ¹⁰B and ¹¹B. Previous measurements of the EMC effect in A ≤ 12 nuclei showed an unexpected nuclear dependence; 10^B and 11^B were measured to explore the EMC effect in this region in more detail. Results are presented for ⁹Be, ¹⁰B, ¹¹B, and ¹²C at an incident beam energy of 10.6 GeV. The EMC effect in the boron isotopes was found to be similar to …

Two Approaches To Equality, With Implications For Grutter, Keith N. Hylton

Faculty Scholarship

The question “what is equality?”, applied to the distribution of resources across races, suggests the following answer: when there appears to be no need for a policy that focuses on improving the welfare of one race relative to another. There is another way to approach the same question: equality is when traditionally-recognized paths to advancement do not give preference to or disadvantage an individual because of his race. Notice the difference here is between end-state and process-based notions of equality, a distinction Nozick emphasized in his examination of justice in distribution. Nozick rejected end-state theories of justice in distribution. I …

The New Pornography Wars, Julie A. Dahlstrom

Faculty Scholarship

The world’s largest online pornography conglomerate, MindGeek, has come under fire for the publishing of “rape videos,” child pornography, and nonconsensual pornography on its website, Pornhub. As in the “pornography wars” of the 1970s and 1980s, lawyers and activists have now turned to civil remedies and filed creative anti-trafficking lawsuits against MindGeek and third parties, like payment processing company, Visa. These lawsuits seek not only to achieve legal accountability for online sex trafficking but also to reframe a broader array of online harms as sex trafficking.

This Article explores what these new trafficking lawsuits mean for the future regulation of …

Numerical Simulations Of Radiation Reaction Using Lorentz-Abraham-Dirac Formalism, E. Rogers, B. Terzic, E. Breen, E. Johnson, G. Krafft

Physics Faculty Publications

An accelerating charged particle emits electromagnetic radiation. The motion of the particle is further damped via self-interaction with its own radiation. For relativistic particles, the subsequent motion is described via a correction to the Lorentz force, known as the Lorentz-Abraham-Dirac force. The aim of this research is to use the Lorentz-Abraham-Dirac force to computationally simulate the radiation damping that occurs during nonlinear inverse Compton scattering. We build on our previous work and the code which simulates single-emission inverse Compton scattering to incorporate the effect of multiple emissions, thereby modeling the radiation reaction.

The Ghosts Of Chevron Present And Future, Gary S. Lawson

Faculty Scholarship

In the October 2021 term, the Supreme Court decided six cases involving federal agency interpretations of statutes, at least five of which seemingly implicated the Chevron doctrine and several of which explicitly turned on applications of Chevron in the lower courts. But while the Chevron doctrine has dominated federal administrative law for nearly four decades, not a single majority opinion during the term even cited Chevron. Three of those cases formalized the so-called “major questions” doctrine, which functions essentially as an anti-Chevron doctrine by requiring clear congressional statements of authority to justify agency action on matters of great legal and …

Questions Of Intellectual Property And Fundamental Values In The Digital Age, Jessica Silbey

Faculty Scholarship

Today's intellectual property debates, in both law and the larger society, are a bellwether of changing justice needs in the twenty-first century. As the digital age democratizes technological opportunities, it brings intellectual property law into mainstream everyday culture. This generates debates about the relationship between the constitutional interest in "the progress of science and useful arts" and other fundamental values, such as equality, privacy, and distributive justice. These values, which were not explicitly part of intellectual property regimes in prior eras, are especially challenged in today's internet world.

The article (which was presented as the annual Nies Lecture in April …

Large-Scale Network Connectivity And Cognitive Function Changes After Exercise Training In Older Adults With Intact Cognition And Mild Cognitive Impairment, Junyeon Won, Kristy A. Nielson, J. Carson Smith

Psychology Faculty Research and Publications

Background:

Despite growing evidence regarding the association between exercise training (ET) and functional brain network connectivity, little is known about the effects of ET on large-scale within- and between-network functional connectivity (FC) of core brain networks.

Objective:

We investigated the effects of ET on within- and between-network functional connectivity of the default mode network (DMN), frontoparietal network (FPN), and salience network (SAL) in older adults with intact cognition (CN) and older adults diagnosed with mild cognitive impairment (MCI). The association between ET-induced changes in FC and cognitive performance was examined.

Methods:

33 older adults (78.0±7.0 years; 16 MCI and 17 …
