Using Multiple Lenses To See An Invisible Group, Kathleen J. Farkas, Jaroslaw Richard Romaniuk

Faculty Scholarship

Social work in Poland and in the United States shares the values of human dignity and self-determination, but there are often value conflicts in terms of how various groups experience social roles and social expectations. This paper explores the use of multiple lenses to understand the past and current conditions for LGBT+ people in Poland. An international, university-level collaboration uses a framework of “invisible groups” to highlight the needs of those who are on the margins of society and whose human and individual rights are suppressed. The article reviews the results of a recently published on-line survey of LGBT+ populations …

Modified Newtonian Dynamics As An Alternative To The Planet Nine Hypothesis, Harsh Mathur

Faculty Scholarship

A new class of Kuiper Belt objects (KBOs) that lie beyond Neptune with semimajor axes greater than 250 astronomical units show orbital anomalies that have been interpreted as evidence for an undiscovered ninth planet. We show that a modified gravity theory known as modified Newtonian dynamics (MOND) provides an alternative explanation for the anomalies using the well-established secular approximation. We predict that the major axes of the orbits will be aligned with the direction toward the Galactic center and that the orbits cluster in phase space, in agreement with observations of KBOs from the new class. Thus, MOND, which can …

Superfluid Dark Matter In Tension With Weak Gravitational Lensing Data, Tobias Mistele, Stacy S. Mcgaugh

Faculty Scholarship

Superfluid dark matter (SFDM) is a model that promises to reproduce the successes of both particle dark matter on cosmological scales and those of Modified Newtonian Dynamics (MOND) on galactic scales. SFDM reproduces MOND only up to a certain distance from the galactic center, and only for kinematic observables: it does not affect trajectories of light. We test whether this is consistent with a recent analysis of weak gravitational lensing that has probed accelerations around galaxies to unprecedentedly large radii. This analysis found the data to be close to the prediction of MOND, suggesting they might be difficult to fit …

Prevalence Of Adulteration In Dietary Supplements And Recommendations For Safe Supplement Practices In Sport, Andrew R. Jagim, Patrick Harty, Jacob L. Erickson, Grant M. Tinsley, Dan Garner, Andrew J. Galpin

Faculty Scholarship

The prevalence of dietary supplement use among athletes continues to rise with 60–80% of athletes often reporting current or previous use of dietary supplements. While select dietary ingredients have been shown to improve acute performance and enhance training adaptations over time, it is important to still consider the risk vs. reward for athletes before opting to consume a dietary supplement. Previous work has indicated that certain dietary supplements may pose risks for inadvertent doping, may be susceptible to mislabelling, could be banned by certain governing bodies of sport, or pose health risks for certain populations. The purpose of the current …

Shared Cinematic Experience And Emerging Technologies: Integrating Mixed-Reality Components For The Future Of Cinema, James Hutson

Faculty Scholarship

The enduring appeal of traditional cinema viewing in the face of alternative experiences, including streaming services and emerging technologies, such as extended reality, is rooted in its esthetic, cultural, and social significance. While the psychological appeal of shared cinematic experiences has gained attention in scholarship, there is a need to further explore the potential enhancement of these experiences through the integration of immersive technologies. The communal nature of cinema fosters social connection, especially in a post-pandemic context marked by widespread social isolation. This study highlights the psychological benefits of shared cinematic experiences and emphasizes the next phase of cinematic evolution, …

Thermoresponsive Polymers With Lcst Transition: Synthesis, Characterization, And Their Impact On Biomedical Frontiers, Yichun Yuan, Konpal Raheja, Nathalie B. Milbrandt, Sophia Beilharz, Steffy Tene, Solomon Oshabaheebwa, Umut A. Gurkan, Anna Cristina S. Samia, Metin Karayilan

Faculty Scholarship

Advances in thermoresponsive materials have significantly impacted many biomedical fields. The unique behavior of reversible phase transition close to the physiological temperatures makes these types of materials a great candidate for a wide variety of biomedical applications including bioimaging, biosensing, injectables, smart surfaces, adhesives, biomanufacturing, and tissue engineering. Thermoresponsive behavior, mainly lower critical solution temperature (LCST) can be easily tuned by shifting the balance between hydrophobicity and hydrophilicity (e.g., by using comonomers or changing end groups) and modifying the molecular weight and architecture of the polymer. Hence, synthetic and characterization tools are critical in tailoring and precisely determining these properties. …

Hydrodynamic Voltammetry Of Fe2+/3+ In Aqueous Deep Eutectic Solvents Towards Redox Flow Batteries, Desiree Mae Prado, Xiaochen Shen, Robert Savinell, Clemens Burda

Faculty Scholarship

Deep eutectic solvents (DESs) have recently attracted much attention as potential green electrolyte solvents for redox flow batteries. DESs are considered not only as environmentally sustainable but also economically attractive electrolytes because they can be resourced from biological feedstock (alcohols, urea, choline) and are earth-abundant and of low toxicity. Despite these advantages, DESs still have limitations in important aspects such as reactant and ion transport, which is inhibited due to hydrogen-bonding-induced viscosity. Thus, improving the transport properties of redox species in DESs is essential. In addition, we explore the quantitative addition of water to ethaline (a 1:2 choline chloride: ethylene …

Measuring Galaxy Cluster Mass Profiles Into The Low-Acceleration Regime With Galaxy Kinematics, Pengfei Li, Stacy S. Mcgaugh

Faculty Scholarship

We probed the dynamical mass profiles of ten galaxy clusters from the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS) using galaxy kinematics. We numerically solved the spherical Jeans equation and parameterize the dynamical mass profile and the galaxy velocity anisotropy profile using two general functions to ensure that our results are not biased toward any specific model. The mass-velocity anisotropy degeneracy is ameliorated by using two virial shape parameters that depend on the fourth moment of velocity distribution. The resulting velocity anisotropy estimates consistently show a nearly isotropic distribution in the inner regions, with an increasing radial anisotropy toward large …

Aether Scalar Tensor Theory Confronted With Weak Lensing Data At Small Accelerations, Tobias Mistele, Stacy S. Mcgaugh

Faculty Scholarship

Context. The recently proposed aether scalar tensor (AeST) model reproduces both the successes of particle dark matter on cosmological scales and those of modified Newtonian dynamics (MOND) on galactic scales. But the AeST model reproduces MOND only up to a certain maximum galactocentric radius. Since MOND is known to fit very well to observations at these scales, this raises the question of whether the AeST model comes into tension with data. Aims. We tested whether or not the AeST model is in conflict with observations using a recent analysis of data for weak gravitational lensing. Methods. We solved the equations …

Neuroaffirmative Approaches To Extended Reality: Empowering Individuals With Autism Spectrum Condition Through Immersive Learning Environments, James Hutson, Caitlyn Mcginley

Faculty Scholarship

Traditional teaching and working environments often prioritize extroverted qualities, disadvantaging individuals with conditions that impact social engagement, such as autism spectrum condition (ASC). These individuals usually thrive in calmer, low-key learning environments but face challenges in lecture-style classes, and traditional office environments leading to marginalization in academic and professional settings. This study explores the neuroaffirming potential of extended reality (XR) in creating immersive learning and working environments tailored to the unique needs of individuals with ASC. By focusing on four key factors—indirect social engagement, digital communication preferences, sensory sensitivity, and avatar-based communication—XR technologies can provide a supportive and accommodating environment …

Virtual Learning Environments And Digital Twins: Enhancing Accessibility, Diversity, And Flexibility In Training Secondary Educational Administrators, James Hutson, Robert Steffes, Joe Weber

Faculty Scholarship

This study investigates the potential of Virtual Learning Environments (VLEs) and digital twins to overcome geo-graphical, scheduling, and diversity barriers in the training of secondary educational administrators. Recognizing the limitations in traditional in-person visits to schools-particularly for graduate students in rural areas and those working fulltime with dependents-and the current ethnic composition of educational administrators, where White individuals comprise 64.5% of the population in the US (71.01% for principals), this research explores how VLEs can democratize access and foster diversity in educational leadership training. Over the academic year 2022–2023, pre- and post-engagement surveys were administered to students in a Visionary …

Legal Clutter: How Concurring Opinions Create Unnecessary Confusion And Encourage Litigation, Meg Penrose

Faculty Scholarship

Good judges are clear writers. And clear writers avoid legal clutter. Legal clutter occurs when judges publish multiple individually written opinions that are neither useful nor necessary. This essay argues that concurring opinions are the worst form of legal clutter. Unlike majority opinions, concurring opinions are legal asides, musings of sorts—often by a single judge—that add length and confusion to an opinion often without adding meaningful value. Concurring opinions do not change the outcome of a case. Unlike dissenting opinions, they do not claim disagreement with the ultimate decision. Instead, concurring opinions merely offer an idea or viewpoint that failed …

Tutorial: Using Neuron For Neuromechanical Simulations, Hillel J. Chiel, Peter J. Thomas

Faculty Scholarship

The dynamical properties of the brain and the dynamics of the body strongly influence one another. Their interaction generates complex adaptive behavior. While a wide variety of simulation tools exist for neural dynamics or biomechanics separately, there are few options for integrated brain-body modeling. Here, we provide a tutorial to demonstrate how the widely-used NEURON simulation platform can support integrated neuromechanical modeling. As a first step toward incorporating biomechanics into a NEURON simulation, we provide a framework for integrating inputs from a “periphery” and outputs to that periphery. In other words, “body” dynamics are driven in part by “brain” variables, …

Differential Expression Of Genes Involved In The Chronic Response To Intracortical Microelectrodes, Sydney S. Song, Lindsey N. Druschel, E. Ricky Chan, Jeffrey R. Capadona

Faculty Scholarship

Brain-Machine Interface systems (BMIs) are clinically valuable devices that can provide functional restoration for patients with spinal cord injury or improved integration for patients requiring prostheses. Intracortical microelectrodes can record neuronal action potentials at a resolution necessary for precisely controlling BMIs. However, intracortical microelectrodes have a demonstrated history of progressive decline in the recording performance with time, inhibiting their usefulness. One major contributor to decreased performance is the neuroinflammatory response to the implanted microelectrodes. The neuroinflammatory response can lead to neurodegeneration and the formation of a glial scar at the implant site. Historically, histological imaging of relatively few known cellular …

Thieno[3,4-D]Pyrimidin-4(3h)-Thione: An Effective, Oxygenation Independent, Heavy-Atom-Free Photosensitizer For Cancer Cells, Luis A. Ortiz-Rodríguez, Sean J. Hoehn, Heather J. Folkwein, Liraz Levi, Carlos E. Crespo-Hernández

Faculty Scholarship

All-organic, heavy-atom-free photosensitizers based on thionation of nucleobases are receiving increased attention because they are easy to make, noncytotoxic, work both in the presence and absence of molecular oxygen, and can be readily incorporated into DNA and RNA. In this contribution, the DNA and RNA fluorescent probe, thieno[3,4-d]pyrimidin-4(1H)-one, has been thionated to develop thieno[3,4-d]pyrimidin-4(3H)-thione, which is nonfluorescent and absorbs near-visible radiation with about 60% higher efficiency. Steady-state absorption and emission spectra are combined with transient absorption spectroscopy and CASPT2 calculations to delineate the electronic relaxation mechanisms of both pyrimidine derivatives in aqueous and acetonitrile solutions. It is demonstrated that thieno[3,4-d]pyrimidin-4(3H)-thione …

Living Apart After Adoption Or Guardianship: Perspectives Of Adoptive Parents And Guardians, Nancy Rolock, Amy E. Korsch-Williams, Chelsea Flanigan

Faculty Scholarship

Background: For children who are not reunified with their biological family members, the child welfare system promotes legal permanence through adoption or guardianship. The intent of adoption and guardianship is a safe home where children develop familial relationships that last a lifetime. However, issues may arise that result in children or youth living apart (LA) from their families after adoption or guardianship. In this study, LA is defined as a youth living outside the home after adoption or guardianship for two weeks or longer because the youth was receiving treatment in a residential or hospital setting, in a juvenile justice …

Bullying Victimization And Perpetration: Some Answers And More Questions, Dexter R. Voisin, David B. Miller

Faculty Scholarship

The U.S. government has defined bullying victimization as “any unwanted aggressive behavior(s) by another youth or group of youths who are not siblings or current dating partners that involves an observed or perceived power imbalance and is repeated multiple times or is highly likely to be repeated”.1 Conceptualizations of bullying and the use of the term vary by audience and context. For instance, for some, bullying behaviors might include acts of aggression or violence, whereas for others bullying might center on name-calling, exclusionary social practices or even spreading rumors and vicious lies.2

Field Studies Of Perc And Al-Bsf Pv Module Performance Loss Using Power And I-V Timeseries, Alan J. Curran, Xuanji Yu, Jiqi Liu, Laura S. Bruckman, Roger H. French

Faculty Scholarship

We have studied the degradation of both full-sized modules and minimodules with PERC and Al-BSF cell variations in fields while considering packaging strategies. We demonstrate the implementations of data-driven tools to analyze large numbers of modules and volumes of timeseries data to obtain the performance loss and degradation pathways. This data analysis pipeline enables quantitative comparison and ranking of module variations, as well as mapping and deeper understanding of degradation mechanisms. The best performing module is a half-cell PERC, which shows a performance loss rate (PLR) of −0.27 ± 0.12% per annum (%/a) after initial losses have stabilized. Minimodule studies …

The Role Of Faculty In Durable Skills Development In Higher Education, James Hutson, Mark Valenzuela, Shannon Wright, Elizabeth Melick

Faculty Scholarship

Although Emsi and other market researchers have found that employers desire durable skills (formerly known as “soft skills”) in new hires, there have been few studies dedicated to identifying how faculty perceptions of skill development differ in degree and by area, and how that might impact how such skills are embedded in classroom instruction. This study proposes to investigate the perceptions of faculty from different academic backgrounds and how their disciplines and experiences may contribute to their perceived role in curricular, cocurricular or extracurricular offerings that support durable skill development. Results from the study demonstrate the differing perspectives and expectations …

"Knock-Knock" ... "Who's There?": The Fourth Amendment Dilemma Posed By Warrantless Police Encounters At Home, Meg Penrose

Faculty Scholarship

In a world where police abuses of power seem more common, where are the judges-particularly the originalist judges-who strive to protect the Founder's intentions? How is it that people living in certain states seemingly have less robust Fourth Amendment protections than others? This essay seeks to answer these questions and urges the Supreme Court to reassert its constitutional commitment to the Fourth Amendment so that all of us are, in fact, secure in our homes. The Court should accept the responsibility it has to provide uniform protection to all Americans and clarify the limits on constructive entry. If the Court …

Neuroinclusive Workplaces And Biophilic Design: Strategies For Promoting Occupational Health And Sustainability In Smart Cities, James Hutson, Piper Hutson

Faculty Scholarship

This study aims to investigate the impact of biophilic design on occupational health and productivity, with a particular focus on addressing the needs of diverse populations, including the neurodiverse, during the post-pandemic return to work. With an estimated 15 – 20% of the global population considered neurodiverse, it is crucial to understand and accommodate their specific needs, such as those with attention-deficit hyperactivity disorder, autism spectrum condition, and learning disabilities. These individuals face increased occupational stress, necessitating the development of targeted strategies. The renewed interest in sustainability and employee well-being has led to a resurgence of biophilic design in the …

A Theory Of Interests In The Context Of Hybrid Warfare: It's Complex, Cynthia Alkon, Sanda Kaufman

Faculty Scholarship

We will begin with a discussion about how the hybrid warfare context is different from other conflict contexts. We will describe some complexity aspects that make hybrid warfare challenging to negotiators. We will then discuss whether classical negotiation theory prescriptions apply to a hybrid warfare context, especially regarding interests. We will argue that these prescriptions related to classical negotiations are unlikely to work in this context. We will focus our analysis on a subset of hybrid warfare attacks, consisting of short-term, time-sensitive, high-risk crises, where negotiations are possible and necessary, such as ransom demands, rather than on hybrid warfare situations …
