Population and Public Health Science Faculty Publications

Objectives: There is evidence showing that children's proficiency in fundamental movement skills (FMS) is positively related to weight status, physical activity, fitness levels, cognitive development, as well as academic performance. Yet, the feasibility of FMS assessment is challenging, especially with relatively large samples of children. This article presents a new tool named Meu Educativo® to assess children's FMS levels, including its validity and reliability. Methods: We relied on the validity evidence approach based on test content to develop the FMS assessment checklist and the rating system with a team of experts. In this article, we used five FMS (stationary dribbling, …

Absence Of Quantization In The Circular Photogalvanic Effect In Disordered Chiral Weyl Semimetals, Ang Kun Wu, Daniele Guerci, Yixing Fu, Justin H. Wilson, J. H. Pixley

Faculty Publications

The circularly polarized photogalvanic effect (CPGE) is studied in chiral Weyl semimetals with short-range quenched disorder. Without disorder, the topological properties of chiral Weyl semimetals lead to quantization of the CPGE, which is a second-order optical response. Using a combination of diagrammatic perturbation theory in the continuum and exact numerical calculations via the kernel polynomial method on a lattice model, we show that disorder perturbatively destabilizes the quantization of the CPGE.

Links Between Optical And X-Ray Light In Cygnus X-2, Alexander B. Igl, R. I. Hynes, K. S. O'Brien, E. L. Robinson, C. T. Britt

Faculty Publications

We observed the low-mass X-ray binary Cyg X-2 for a total of 18 nights over two observing runs in July and September of 2006, using the Otto Struve Telescope at McDonald Observatory and the Rossi X-ray Timing Explorer. Using discrete cross-correlations, we found peaks occurring at near-zero lags in the flaring branch of the colour-colour diagram, which could signify reprocessing, in addition to an anticorrelation within the normal branch. When comparing optical flux to the system's placement on the Z track, two distinct behaviours were seen: (1) a state with no correlation, and (2) a multivalued (horizontal and normal branches)/correlated …

Magnetars are slowly rotating neutron stars that possess the strongest magnetic fields known in the cosmos (10¹⁴-10¹⁵ G). They display a range of transient high-energy electromagnetic activity. The brightest and most energetic of these events are the gamma-ray bursts (GRBs) known as magnetar giant flares (MGFs), with isotropic energies Eiso10⁴⁴10⁴⁶ erg. Only seven MGF detections have been made to date: three unambiguous events occurred in our Galaxy and the Magellanic Clouds, and the other four MGF candidates are associated with nearby star-forming galaxies. As all seven identified MGFs are bright at Earth, additional weaker …

We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwavelength data during the campaign are likewise shown. The 2-8 keV X-rays exhibit a net polarization degree PD = 1.99% ± 0.13% (68% confidence). The polarization signal is found to increase with energy across the Imaging X-ray Polarimetry Explorer’s (IXPE) 2-8 keV bandpass. The polarized X-rays exhibit an energy-independent polarization angle of PA = −25.°7 ± 1.°8 east of north (68% confidence). This is consistent with being aligned to Cyg X-1’s au-scale compact radio …

Out Of Time Order Correlation Of The Hubbard Model With Random Local Disorder, Chakradhar Rangi, Juana Moreno, Ka Ming Tam

Faculty Publications

The out-of-time-order correlator (OTOC) serves as a powerful tool for investigating quantum information spreading and chaos in complex systems. We present a method employing non-equilibrium dynamical mean-field theory and coherent potential approximation combined with diagrammatic perturbation on the Schwinger-Keldysh contour to calculate the OTOC for correlated fermionic systems subjected to both random disorder and electron interaction. Our key finding is that random disorder enhances the OTOC decay in the Hubbard model for the metallic phase in the weakly interacting limit. However, the current limitation of our perturbative solver restricts the applicability to weak interaction regimes.

The Chemistry Of Heavy Elements: Probing Relativistic Chemical Bonding, Barbara Maria Teixeira Costa Peluzo

Chemistry Theses and Dissertations

The bottommost part of the periodic table has a unique chemistry, where the high velocities of the inner-shell electrons prevent their description by the usual Schrödinger equation. The resulting so-called relativistic effects have numerous chemical implications, on both macro and microscale, ranging from physical properties to reactivity. However, experimental probes on these intriguing atoms are limited by their natural availability and, more importantly, the danger associated with their radioactivity. Quantum chemical calculations, on the other hand, face the challenge of far more complex algebra, which demands substantial computational resources. Relativistic Hamiltonians, which act over all electrons in the system, are …

Reducing Cesarean Sections With Peanut Ball Use: A Quality Improvement Project, Alexi Rivera Bsn, Rn

DNP Projects

Cesarean sections, although sometimes medically necessary, carry multiple risks and complications. Movement and frequent repositioning throughout labor has been shown to support the natural physiologic process of birth, leading to less medical intervention and increased incidences of vaginal deliveries. The peanut ball is a variation of a birthing ball that assists women with this movement and repositioning. The purpose of this quality improvement project was to see if increasing nursing knowledge on peanut ball benefits, risks, and proper technique would reduce cesarean section rates. It is expected that peanut ball use throughout labor would decrease cesarean sections and increase the …

The Blessed Assembly: Irreplaceable Physical Co-Presence In Worship And Healthy Hybridity Reimagined After The Pandemic In The Digital Age, Yvette, Ying Wai Lau

Doctor of Pastoral Music Projects and Theses

Because of the unprecedented and unexpected force of the pandemic since 2020, most churches around the world have experienced some online worship during the lockdown of their cities or the mandated closure of the church buildings. For many people, online worship seems to be an equivalent, if not better, alternative for gathering together—a physical co-presence in worship—even after the pandemic has ended. As necessary and vital as online worship experiences have been for Christians during the pandemic, the witness of the church from Pentecost throughout Christian history indicates that gathered worship in physical spaces is irreplaceable for faith formation and …

Increasing Colorectal Cancer Screening Rates In Adults Aged 45-49 At An Urban Fqhc: A Quality Improvement Project, Meredith Gentes

Imperfect Insanity And Diminished Responsibility, E. Lea Johnston

UF Law Faculty Publications

Insanity’s status as an all-or-nothing excuse results in the disproportionate punishment of individuals whose mental disorders significantly impaired, but did not obliterate, their capacities for criminal responsibility. Prohibiting the trier of fact from considering impairment that does not meet the narrow definition of insanity contradicts commonly held intuitions about mental abnormality and gradations of responsibility. It results in systemic over-punishment, juror frustration, and, at times, arbitrary verdicts as triers of fact attempt to better apportion liability to blameworthiness.

This Article proposes a generic partial excuse: Diminished Responsibility from Mental Disability. This excuse could be asserted as an affirmative defense at …

Taxation Of Information And The Data Revolution, Yariv Brauner

UF Law Faculty Publications

Existing and universal income tax rules are inherently incompatible with an economy in which information-based transactions play a significant role. This Article contends that income taxation is incapable of taxing information effectively. It goes on to argue that this incapability currently necessitates reform, and it offers three viable paths to such reform: consumption taxation, data taxes, and formulary taxation. The Article concludes that formulary taxation is currently the most desirable and plausible path to effective reform, owing to its promise to best stabilize and maintain the legitimacy of the international tax regime.

Explaining The Comprehensive Immigration Reform Stalemate In Congress, Maryam T. Stevenson

Catholic University Law Review

Historically, congressional policy goals on immigration have vacillated from open to restrictive as various micro and macro level factors have changed both inside and outside the Beltway. While Congress has been subjected to some immigration lobbies over time, it has largely been isolated from a general public opinion on immigration policy until fairly recently. Specifically, while Congress was successful at passing a variety of immigration policies through 1990 without much regard to public opinion, it has since failed even amid bipartisan congressional and presidential support. This article will offer a number of theories in order to explain why Congress has …

Dude, Where’S My Data? A Legislative Band-Aid For Data Brokers’ Bullet Hole In Consumer Privacy Protection, Emily Bushman

Catholic University Law Review

The development and proliferation of the Internet, GPS, cell phones, social media, and the associated data that support these now ubiquitous technologies have created a new ecosystem of information making up a person’s digital identity. Our digital footprints have traditionally been subject to different levels of privacy protection depending upon the kind of data at issue. Over time, court decisions have revealed tensions and a lack of consistency on the question of how the protections guaranteed by the Fourth Amendment apply to an individual’s digital footprint and their reasonable expectations of privacy over it. This Comment will examine the gaps …
