A Discrete Choice Experiment Investigating Hiv Testing Preferences In South Africa, P. Chiwire, A. C. Muhlbacher, S. M. Evers, H. Mahomed, Jan Ostermann Ph.D., M. Hiligsmann

Faculty Publications

Background

South Africa (SA) has the world’s highest burden of HIV infection, with an estimated 13.7% of the population living with HIV (PLWH/Persons Living With HIV). The early identification of PLWH and rapid engagement of them in HIV treatment are indispensable tools in the fight against HIV transmission. Understanding client preferences for HIV testing may help improve uptake. This study aimed to elicit client preferences for key characteristics of HIV testing options.

Methods

A discrete-choice experiment (DCE) was conducted among individuals presenting for HIV testing at two public primary healthcare facilities in Cape Town, South Africa. Participants were asked to …

Implementation Of An Automated Grading Tool For Phonetic Transcription Training, Marisha Speights Atkins, Dallin J. Bailey, Cheryl D. Seals

Faculty Publications

Clinical phonetic transcription is regarded as a highly specialised skill requiring hours of practice for mastery. Although this skill is a critical part of students’ clinical preparation to become speech-language pathologists, students often report feeling unprepared to apply the skill in clinical practice. Previous studies suggest that increased opportunities for practice and timely feedback on transcriptions are needed in order to develop skill confidence. However, providing more opportunities for practice can be impeded by the limited resources to manage the grading of additional assignments. The purpose of this study is to show the implementation of a web-based learning management system …

Environment And Co-Occurring Native Mussel Species, But Not Host Genetics, Impact The Microbiome Of A Freshwater Invasive Species (Corbicula Fluminea), Marlène Chiarello, Jamie R. Bucholz, Mark Mccauley, Stephanie N. Vaughn, Garrett W. Hopper, Irene Sánchez González, Carla L. Atkinson, Jeffrey D. Lozier, Colin R. Jackson

Faculty Publications

The Asian clam Corbicula fluminea (Family: Cyneridae) has aggressively invaded freshwater habitats worldwide, resulting in dramatic ecological changes and declines of native bivalves such as freshwater mussels (Family: Unionidae), one of the most imperiled faunal groups. Despite increases in our knowledge of invasive C. fluminea biology, little is known of how intrinsic and extrinsic factors, including co-occurring native species, influence its microbiome. We investigated the gut bacterial microbiome across genetically differentiated populations of C. fluminea in the Tennessee and Mobile River Basins in the Southeastern United States and compared them to those of six co-occurring species of native freshwater mussels. …

Faster Intercalation Pseudocapacitance Enabled By Adjustable Amorphous Titania Where Tunable Isomorphic Architectures Reveal Accelerated Lithium Diffusivity, Wessel Van Den Bergh, Taylor Larison, Maximilliano Jesus Jara Fornerod, Prof. Stefan Guldin, Morgan Stefik

Faculty Publications

Intercalation pseudocapacitance is a faradaic electrochemical phenomenon with high power and energy densities, combining the attractive features of capacitors and batteries, respectively. Intercalation pseudocapacitive responses exhibit surface-limited kinetics by definition, without restriction from the collective of diffusion-based processes. The surface-limited threshold (SLT) corresponds to the maximum voltage sweep rate (vSLT) exhibiting a predominantly surface-limited current response prior to the onset of diffusion-limitations. Prior studies showed increased lithium diffusivity for amorphous titania compared to anatase. Going beyond prior binary comparisons, here a continuum of amorphous titania configurations were prepared using a series of calcination temperatures to tailor both amorphous …

Atmospheric Plasma Spraying To Fabricate Metal-Supported Solid Oxide Fuel Cells With Open-Channel Porous Metal Support, Jie Lin, Haixia Li, Wanhua Wang, Peng Qiu, Greg Tao, Kevin Huang, Fanglin Chen

Faculty Publications

Metal-supported solid oxide fuel cells (MS-SOFCs) have been fabricated by applying phase-inversion tape-casting and atmospheric plasma spraying (APS). The effect of the binder amount of the phase-inversion slurries on the microstructure development of the 430L stainless steel metal support was investigated. The pore structures, the viscosity of the slurry, porosity and permeability of the as-prepared metal supports are significantly influenced by the amount of the binder. NiO–scandia-stabilized zirconia (ScSZ) anode, ScSZ electrolyte and La_0.6Sr_0.4Co_0.2Fe0.8O_3−δ (LSCF) cathode layers were consecutively deposited on the metal support with an ideal microstructure by APS process. The effect …

Maternal Depression Moderated By Family Resources When Children Have Developmental Disabilities., Timothy B. Smith, Terisa P. Gabrielsen

Faculty Publications

Children with developmental disabilities require extensive parental involvement in intervention, but parents with depression may be less able to intervene effectively. We examined prevalence of depression symptoms and predictors among 131 mothers of children with disabilities enrolled in early childhood special education. Participants completed several self-report measures of depression and child and family functioning. Children were directly evaluated using the Battelle Developmental Inventory. One year later, 68 mothers repeated self-report measures. Participants (30%) reported elevated depression symptoms across time. Depression scores were correlated with parental stress and family resources. An interaction between higher maternal depression and higher child functioning with …

Visual Homing For Robot Teams: Do You See What I See?, Damian Lyons, Noah Petzinger

Faculty Publications

Visual homing is a lightweight approach to visual navigation which does not require GPS. It is very attractive for robot platforms with a low computational capacity. However, a limitation is that the stored home location must be initially within the field of view of the robot. Motivated by the increasing ubiquity of camera information we propose to address this line-of-sight limitation by leveraging camera information from other robots and fixed cameras. To home to a location that is not initially within view, a robot must be able to identify a common visual landmark with another robot that can be used …

Development And Structural Organization Of Mexico’S Mangrove Monitoring System (Smmm) As A Foundation For Conservation And Restoration Initiatives: A Hierarchical Approach, María Teresa Rodríguez-Zúñiga, Carlos Troche-Souza, María Isabel Cruz-López, Victor H. Rivera-Monroy

Faculty Publications

Mangroves provide ecosystem services worth billions of dollars worldwide. Although countries with extensive mangrove areas implemented management and conservation programs since the 1980s, the global area is still decreasing. To recuperate this lost area, both restoration and rehabilitation (R/R) projects have been implemented but with limited success, especially at spatial scales needed to restore functional properties. Monitoring mangroves at different spatial scales in the long term (decades) is critical to detect potential threats and select cost-effective management criteria and performance measures to improve R/R program success. Here, we analyze the origin, development, implementation, and outcomes of a country-level mangrove monitoring …

Rights To Nowhere: The Idea's Inadequacy In High-Poverty Schools, Claire Raj

Faculty Publications

The Individuals with Disabilities Education Act (“IDEA”) successfully opened the schoolhouse doors to millions of students with disabilities. But more than forty years after its enactment, the law has proven largely inept at confronting the educational inequities faced by the many students with disabilities attending underfunded, high-poverty public schools. This shortcoming is inconsistent with common conceptions of the IDEA: Advocates and policymakers alike treat the IDEA’s rights and privately enforceable remedies as strong, meaningful tools. This Article theorizes that the IDEA’s under-appreciated failures are overlooked because they are the products of the law’s internal structure, undue judicial deference to schools, …

Taxing Choices, Tessa R. Davis

Faculty Publications

Tax has a choice problem. At all stages of the making of tax, choice plays a role. Lawmakers consider how tax will impact the range and appeal of choices available to an individual. Scholars critique how tax may drive an individual toward or away from a given choice. Courts craft stories of how an individual had either free or deeply constrained choice, using their perception of the facts to guide their interpretation of tax law. And yet for all the seeming relevance of choice to tax, we have no clear definition of what we mean when we talk about choice …

Cortical Source Analysis Of Event-Related Potentials: A Developmental Approach, Stefania Conte, John E. Richards

Faculty Publications

Cortical source analysis of electroencephalographic (EEG) signals has become an important tool in the analysis of brain activity. The aim of source analysis is to reconstruct the cortical generators (sources) of the EEG signal recorded on the scalp. The quality of the source reconstruction relies on the accuracy of the forward problem, and consequently the inverse problem. An accurate forward solution is obtained when an appropriate imaging modality (i.e., structural magnetic resonance imaging - MRI) is used to describe the head geometry, precise electrode locations are identified with 3D maps of the sensor positions on the scalp, and realistic conductivity …

States Can Infringe Upon Your Intellectual Property Rights With Impunity In The Era Of "New Federalism", Homayoon Rafatijo, Dennis D. Crouch

Faculty Publications

Antagonized by half a century of insouciance toward federalism boundaries, the "New Federalism" revival began under Chief Justice Rehnquist. As part of this revival, the Rehnquist Court substantially restrained Congress's authority to regulate commerce, abrogate sovereign immunity, fashion remedies pursuant to Section 5 of the Fourteenth Amendment, and "commandeer" state officials. The New Federalism has continued in the Roberts Court Era, most recently in a case weighing congressionally enacted copyright policy against the sovereignty of individual states to disregard copyright. In Allen v. Cooper, a unanimous Supreme Court held that Congress's express power under Article I is not a …

Search For Gravitational Waves Associated With Gamma-Ray Bursts Detected By Fermi And Swift During The Ligo-Virgo Run O3b, R. Abbott

Faculty Publications

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC-2020 March 27 17:00 UTC). We conduct two independent searches: a generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence …
