A Right To Be Left Dead, Mark Bartholomew

Journal Articles

Technology forces us to contemplate a counterpart to the right of privacy—Brandeis and Warren’s “right to be let alone”—for the age of artificial intelligence: the right to be left dead. Traditionally, it has been presumed that even if Brandeis and Warren’s right constitutes “the most comprehensive of rights and the right most valued by civilized men,” it does not apply to the dead. The question is whether we need a new approach at a time when technology can reanimate anyone and make them behave in a manner indistinguishable from their living presence. This Article interrogates the need for a right …

A Systems Theory-Based Framework For Uncertainty In Complex System Governance, Teresa Anne Crater

Engineering Management & Systems Engineering Theses & Dissertations

Complex systems are all around. A complex system is a system whose collective behavior is more than the behavior exhibited by the individual parts. Such a system is characterized by an exponential increase in information, complexity, ambiguity, emergence, and high levels of uncertainty (Jaradat, 2015). Uncertainty is intrinsic to complex systems. Uncertainty refers to epistemic situations involving imperfect or unknown information. Uncertainty can refer to the chance of certain anticipated outcomes occurring, or it can refer to the unknown events that are not foreseeable as to when or if one might occur. It applies to predictions of future events, to …

Finding Language For The Experience Of Pltl, A.E. Dreyfuss, Lesley Howell, Maria Cecilia Barone, Sofia Delgado, Sally Faulkner, Ana Fraiman, Robin Frye, Redwan Shahid

Publications and Research

The purpose of this paper is to share a means of communicating why Peer-Led Team Learning (PLTL) has provided a sense of deep connection among practitioners, including Peer Leaders, faculty and administrators. To arrive at finding the qualitative language of emotions, three discussion sessions were facilitated over the course of three days during the 11th Annual Conference of the Peer-Led Team Learning International Society (June 2023, University of Houston Downtown). Facilitators’ techniques, prompts and the necessary pivots used to question assumptions are presented. We found that despite the many variations in the institutions where PLTL is practiced, we are united …

The P-Adic Schrödinger Equation And The Two-Slit Experiment In Quantum Mechanics, Wilson A. Zuniga-Galindo

School of Mathematical & Statistical Sciences Faculty Publications

p-Adic quantum mechanics is constructed from the Dirac-von Neumann axioms identifying quantum states with square-integrable functions on the N-dimensional p-adic space, Q_{p}^{N}. This choice is equivalent to the hypothesis of the discreteness of the space. The time is assumed to be a real variable. p-Adic quantum mechanics is the response to the question: what happens with the standard quantum mechanics if the space has a discrete nature? The time evolution of a quantum state is controlled by a nonlocal Schrödinger equation obtained from a p-adic heat equation by a temporal Wick rotation. This p-adic heat equation describes a particle performing …

On Helly Numbers For Crystals And Cut-And-Project Sets, Alexey Garber

We prove existence of Helly numbers for crystals and for cut-and-project sets with convex windows. Also we show that for a two-dimensional crystal consisting of 𝑘 copies of a single lattice the Helly number does not exceed 𝑘 + 6.

Testing The Reliability Of Chatgpt In Providing Spectral Information Of Organic Molecules, Ana Fraiman, Paola Barron, Brooke Dorsey, Sofia A. Delgado, Emanuel Sanchez

School of Mathematical & Statistical Sciences Faculty Publications

ChatGPT has emerged as a tool for predicting Hydrogen-1 Nuclear Magnetic Resonance (1HNMR), Infrared (IR), and Mass Spectrometry (MS) spectra. In order to rely on ChatGPT as a tool, a proof of concept for its application was essential. Having the ChatGPT outputs be validated by experimental data and databases (SDBS) has proven valuable for future uses. By inference, ChatGPT spectra output can be used to design problems without interference of copyright infringement of existing databases.

Search For Eccentric Black Hole Coalescences During The Third Observing Run Of Ligo And Virgo, A. G. Abac, R. Abbott, H. Abe, Teviet Creighton, Mario C. Diaz, Francisco Llamas Villarreal, Soma Mukherjee, Gaukhar Nurbek, Volker Quetschke, Wenhui Wang

Physics & Astronomy Faculty Publications

Despite the growing number of binary black hole coalescences confidently observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include the effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that have already been identified with searches focusing on …

The Cretaceous Diatom Database: A Tool For Investigating Early Diatom Evolution, Karolina Brylka, Matt P. Ashworth, Andrew J. Alverson, David J. Conley

Biological Sciences Faculty Publications and Presentations

The Cretaceous period is the time of the first appearance of the diatoms in the fossil record. These fossils give us direct evidence of the age and early evolution of the diatom lineage. The fossil record, however, is incomplete and therefore often extrapolated through time-calibrated phylogenies. These two approaches offer different perspectives on the early evolution of diatoms, which is still poorly understood. We compiled the first comprehensive Cretaceous Diatom Database, a tool to investigate the taxonomy, diversity, and occurrence of the earliest known diatom lineages. To further aid the integration and use of the oldest diatom fossils in molecular …

The Middle Domain Of Hsp104 Can Ensure Substrates Are Functional After Processing, Hannah Buchholz, Jane E. Dorweiler, Sam Guereca, Brett T. Wisniewski, James Shorter, Anita L. Manogaran

Biological Sciences Faculty Research and Publications

Molecular chaperones play a central role in protein disaggregation. However, the molecular determinants that regulate this process are poorly understood. Hsp104 is an AAA+ ATPase that disassembles stress granules and amyloids in yeast through collaboration with Hsp70 and Hsp40. In vitro studies show that Hsp104 processes different types of protein aggregates by partially translocating or threading polypeptides through the central pore of the hexamer. However, it is unclear how Hsp104 processing influences client protein function in vivo. The middle domain (MD) of Hsp104 regulates ATPase activity and interactions with Hsp70. Here, we tested how MD variants, Hsp104^A503S and …

Cardiomyocyte Adaptation To Exercise: K+ Channels, Contractility And Ischemic Injury, Robert H. Fitts, Xinrui Wang, Wai-Meng Kwok, Amadou K.S. Camara

Biological Sciences Faculty Research and Publications

Cardiovascular disease is a leading cause of morbidity and mortality, and exercise-training (TRN) is known to reduce risk factors and protect the heart from ischemia and reperfusion injury. Though the cardioprotective effects of exercise are well-documented, underlying mechanisms are not well understood. This review highlights recent findings and focuses on cardiac factors with emphasis on K⁺ channel control of the action potential duration (APD), β-adrenergic and adenosine regulation of cardiomyocyte function, and mitochondrial Ca²⁺ regulation. TRN-induced prolongation and shortening of the APD at low and high activation rates, respectively, is discussed in the context of a reduced response …

Neural And Muscular Contributions To The Age-Related Differences In Peak Power Of The Knee Extensors In Men And Women, David J. Wrucke, Andrew Kuplic, Mitchell D. Adam, Sandra K. Hunter, Christopher W. Sundberg

Physical Therapy Faculty Research and Publications

The mechanisms for the loss in limb muscle power output in old (60–79 yr) and very old (≥80 yr) adults and whether the mechanisms differ between men and women are not well understood. We compared maximal peak power of the knee extensor muscles between young, old, and very old men and women and identified the neural and muscular factors contributing to the age-related differences in power. Thirty-one young (22.9 ± 3.0 yr, 15 women), 82 old (70.3 ± 4.9 yr, 38 women), and 16 very old adults (85.8 ± 4.2 yr, 9 women) performed maximal isokinetic contractions at 14 different …

Reducing 30-Day Post-Stroke Readmissions With A Discharge Checklist Tool, Monika Robinson

All Doctor of Nursing Practice (DNP) Scholarly Projects

Reducing Falls Through Enhanced Staff Compliance With The Fall Bundle, Lester Lubuguin

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem:

Patient falls represent a critical issue that incurs significant health and economic burdens for both individuals and healthcare organizations. Annually, falls and fall-related injuries are responsible for nearly 3 million emergency room visits and 1 million hospitalizations, costing an estimated $50 billion. Evidence suggests that a multi-factorial approach—often referred to as a "fall bundle"—is effective in reducing the incidence of falls. However, staff non-compliance with this bundle can undermine its effectiveness.

Aim of the Project:

The project aimed to reduce the incidence of falls by enhancing staff compliance with fall prevention measures through audits and feedback conducted by designated …

Measuring Religious Evil: Examining The Use Of Single-Item Measures In Religious Research, Tom Clark, Scott A. Desmond, Christoper D. Bader

Sociology Faculty Articles and Research

Multiple-item indexes are ubiquitous within the sociology of religion. However, there are a growing number of articles in other disciplines that have advocated the use of single-item measures in specific circumstances. Using quantitative survey data taken from the United Kingdom, this paper contributes to this literature by exploring the impact of single and multiple item measures of religious evil on a series of social and political attitudes. The findings suggest that belief in the devil is the most consistent predictor within a multiple-item measure of religious evil and the multiple-item measure does not significantly outperform single-item measures. Indeed, the item …

Fear Of Widespread Voter Fraud In The United States, Will Basnight

Political Science Student Papers and Posters

Millions claim the 2020 presidential election was stolen; there was even an insurrection to try and stop the election from being certified. Despite the lack of evidence, too many people trust politicians who claim elections were rigged or stolen. In this paper, I will study the type of person who fears widespread voter fraud, what media sources are pushing voter fraud headlines, as well as the patterns in social media usage when related to fearing voter fraud.

I will do this by using the Chapman survey of American fears, a representative national sample of U.S. adults in 2024. I found …

Entwined Derelict, Alex Teeple

Harrisburg University Other Works

"Entwined Derelict" was my first delve into the Twine interactive fiction engine, and the second game that I consider "feature complete". While a significant focus was put on learning the engine as a whole, particular effort for me was put into a sidebar "journal" of sorts, that took narrative flags from the game and recorded the events in a way that allows players to read back what they have experienced in-game at their leisure. While I greatly enjoyed making the game, and I do consider it a complete experience with some unique pieces within, it is a short adventure without …

Examining Relationships Among Nursing Students’ Views Of Suffering, Positive Thinking, And Professional Quality Of Life, Ruth A. Engbers, Abir K. Bekhet, Teresa Jerofke-Owen, Norah L. Johnson, Maharaj Singh

College of Nursing Faculty Research and Publications

Background:

Exposure to suffering can lead to compassion fatigue in undergraduate nursing students.

Objective:

Guided by resilience theory, a cross-sectional, correlational design was used to investigate the potential moderating effect of positive thinking skills on the relationships between views of suffering, compassion fatigue, and compassion satisfaction.

Results:

In 157 undergraduate nursing students, multiple regressions revealed that views of suffering and positive thinking explained 23.8% of the variance in compassion satisfaction (F11,145 = 4.121, P <  .001), and 21.9% of the variance in burnout (F11,144 = 3.786, P <  .001). The Suffering God view, which stresses the presence of a compassionate deity amid suffering, and positive thinking had significant main effects on compassion satisfaction (β = 0.349, P = .025; and β = 0.309, P <  .001, respectively). Positive thinking, the Suffering God view, and the Random view, in which the occurrence of suffering is random and purposeless, had significant main effects on burnout (β = −0.280, P <  .001; β = −0.392, P = .014; and β = −0.206, P = .014, …

College of Nursing Faculty Research and Publications

Background: As rates of substance use during pregnancy persist, the health and optimal development of infants with prenatal substance exposure remain a key priority. Nurses are tasked with identifying and reporting suspected cases of child maltreatment, including abuse and neglect, which is often assumed to be synonymous with substance use during pregnancy. While policies aimed at protecting infants from child abuse and neglect are well intentioned, literature regarding the short- and long-term social and legal implications of mandatory reporting policies is emerging.

Purpose: In this article, we explore the intersections between the condition of substance use in pregnancy and policies …
