Faculty Publications

Blood donation has saved many lives in the past. According to statistics presented by the American Red Cross, a patient is in need of a blood transfusion every two seconds. There are many benefits that arise from blood donation to both the donor and the blood recipients. With blood donation, cancer patients, people involved in accidents, or those battling diseases that require blood donation have access to enough blood to sustain their survival. There is a need to digitize the blood donation booking to facilitate blood donation across the United States, and ensure patients in need of blood, receive their …

Passive Remote Monitoring And Aging In Place: A Scoping Review, Emily Read, Cora Woolsey, Lorie Donelle, Lori Weeks, Norma Chinho

Publications

Passive remote monitoring is a relatively new technology that may support older adults to age in place. However, current knowledge about the effectiveness of this technology in extending older adults' independence is lacking. Therefore, we conducted a scoping review of studies examining passive remote monitoring to systematically synthesize evidence about the technology's effectiveness as an intervention. Our initial search of Embase, CINAHL, PubMed, and Scopus databases identified 486 unique articles. Of these, 14 articles met our inclusion criteria. Results show that passive remote monitoring technologies are being used in innovative and diverse ways to support older adults aging in place …

Increasing numbers of children with known genetic conditions and/or intellectual disability are referred for evaluation of autism spectrum disorder (ASD), highlighting the need to refine autism symptom measures to facilitate differential diagnoses in children with cognitive and language impairments. Previous studies have reported decreased specificity of ASD screening and diagnostic measures in children with intellectual disability. However, little is known about how cognitive and language abilities impact the measurement of specific ASD symptoms in this group. We aggregated a large sample of young children (N = 1196; aged 31-119 months) to examine measurement invariance of ASD symptoms among minimally verbal …

Hair Zidovudine Concentrations Predict Virologic Outcomes Among People Living With Hiv/Aids In China, Yan Wu, Shuaifeng Liu, Liuxi Chu, Quan Zhang, Jin Yang, Shan Qiao, Xiaoming Li Ph.D., Yuejiao Zhou, Huihua Deng, Zhiyong Shen

Faculty Publications

Background: Hair antiretroviral concentrations are an objective and non-invasive measure of adherence to long-term antiretroviral therapy (ART) and can further predict virologic outcomes among people living with HIV/AIDS (PLWH). Zidovudine, one of the mainstream antiretrovirals in China, has been verified to have high reliability in adherence assessment, especially for its hair concentrations. However, data are limited in its predicting virologic outcomes. Therefore, this study aimed to characterize whether hair zidovudine concentrations can predict virologic suppression among Chinese PLWH compared with hair lamivudine concentrations and two self-reported measures, the overall frequency of adherence behaviors and percentage adherence. Methods: This cross-sectional study …

Capturing The Pool Dilution Effect In Group Testing Regression: A Bayesian Approach, Stella Self Ph.D., Ms, Christopher Mcmahan, Stefani Mokalled

Faculty Publications

Group (pooled) testing is becoming a popular strategy for screening large populations for infectious diseases. This popularity is owed to the cost savings that can be realized through implementing group testing methods. These methods involve physically combining biomaterial (eg, saliva, blood, urine) collected on individuals into pooled specimens which are tested for an infection of interest. Through testing these pooled specimens, group testing methods reduce the cost of diagnosing all individuals under study by reducing the number of tests performed. Even though group testing offers substantial cost reductions, some practitioners are hesitant to adopt group testing methods due to the …

Men who have sex with men (MSM) are more likely to use drugs and other substances compared to their heterosexual peers. No studies have evaluated patterns of substance use among MSM adults in Mexico. We used latent class analysis (LCA) to identify MSM subgroups with specific substance use patterns and their associations with sexual behaviors. Methods: Data from 1850 adult MSM were collected at HIV clinics in Mexico City between September 2018 and December 2019. The structural equation modeling approach was used to estimate a LC model to identify patterns of substance use by self-report of substance use (i.e., cigarette …

Nothing Ventured, Nothing Gained: A Meta-Analysis Of Ceo Overconfidence, Strategic Risk Taking, And Performance, Barbara Burkhard, Charlotta Sirén, Marc Van Essen, Dietmar Grichnik, Dean A. Shepherd

Faculty Publications

Although overconfidence is acknowledged as one of the most common managerial decision-making biases, much uncertainty remains about its implications for firm performance. To resolve this uncertainty, we investigate how and why CEO overconfidence is related to firm performance using meta-analytic techniques on a sample of 199 studies. In particular, relying on behavioral decision theory, we develop alternative hypotheses regarding the impact of CEO overconfidence on firm performance. Contrary to the conventional belief that CEO overconfidence is detrimental, this study reveals that CEO overconfidence is, on average, beneficial for firm performance. Drawing on recent refinements of upper echelons theory and theoretical …

Predicting Lattice Vibrational Frequencies Using Deep Graph Neural Networks, Nghia Nguyen, Steph-Yves V. Louis, Lai Wei, Kamal Choudhary, Ming Hu, Jianjun Hu

Faculty Publications

Lattice vibrational frequencies are related to many important materials properties such as thermal and electrical conductivity as well as superconductivity. However, computational calculation of vibrational frequencies using density functional theory methods is computationally too demanding for large number of samples in materials screening. Here we propose a deep graph neural network based algorithm for predicting crystal vibrational frequencies from crystal structures. Our algorithm addresses the variable dimension of vibrational frequency spectrum using the zero padding scheme. Benchmark studies on two data sets with 15,000 mixed-structure and 35,552 rhombohedra samples show that the aggregated R2 scores of the prediction reach …

The Effect Of Social Exclusion On Trust Among Youth Orphaned By Hiv/Aids: Evidence From An Event-Related Potentials Study, Jiaojiao Wan, Qi Zhao, Yafei Zhang, Lili Ji, Junfeng Zhao, Shan Qiao Ph.D., Xiaoming Li Ph.D.

Faculty Publications

Grounded in a follow-up study among children who lost one or both parents to HIV in central China in the early 2000s, we conducted an event-related potentials (ERPs) experiment to explore the effect of social exclusion on trust and the corresponding neurophysiological mechanism among youth orphaned by HIV/AIDS (“AIDS orphans”). A sample of 31 AIDS orphans (26.16 ± 3.34 years old; 15 female) and 32 age and development status matched controls (25.02 ± 3.45 years old; 14 female) participated in the study. They were all assigned to play Cyberball, a virtual ball-tossing game that reliably induced social exclusion (15 orphans, …

Post-Embryonic Phase Transitions Mediated By Polycomb Repressive Complexes In Plants, Valerie Hinsch, Samuel Adkins, Darren Manuela, Mingli Xu

Faculty Publications

Correct timing of developmental phase transitions is critical for the survival and fitness of plants. Developmental phase transitions in plants are partially promoted by controlling relevant genes into active or repressive status. Polycomb Repressive Complex1 (PRC1) and PRC2, originally identified in Drosophila, are essential in initiating and/or maintaining genes in repressive status to mediate developmental phase transitions. Our review summarizes mechanisms in which the embryo-to-seedling transition, the juvenile-to-adult transition, and vegetative-to-reproductive transition in plants are mediated by PRC1 and PRC2, and suggests that PRC1 could act either before or after PRC2, or that they could function independently of each other. …

Predicting Pavement Structural Condition Using Machine Learning Methods, Nazmus Sakib Ahmed, Nathan Huynh, Sarah Gassman, Robert Mullen, Charles Pierce, Yuche Chen

Faculty Publications

State departments of transportation recognize the need to incorporate pavement structural condition in their pavement performance models and/or decision processes used to select candidate projects for preservation, rehabilitation, or reconstruction at the network level. However, pavement structural condition data are costly to obtain. To this end, this paper develops and evaluates the effectiveness of two machine learning methods, Random Forest (RF) and eXtreme Gradient Boosting (XGBoost), for predicting a flexible pavement’s structural condition. The aim is to be able to predict whether a pavement section’s structural condition is poor or not based on Annual Average Daily Traffic (AADT), truck percentage, …

Age-Related Changes In Diffuse Optical Tomography Sensitivity Profiles From Childhood To Adulthood, Xiaoxue Fu Ph.D., John E. Richards

Faculty Publications

Significance: Diffuse optical tomography (DOT) uses near-infrared light spectroscopy to measure changes in cerebral hemoglobin concentration. Anatomical interpretations of the brain location that generates the hemodynamic signal require accurate descriptions of the DOT sensitivity to the underlying cortex. DOT sensitivity profiles are different in infants compared with adults. However, the descriptions of DOT sensitivity profiles from early childhood to adulthood are lacking despite the continuous head and brain development.

Aim: We aim to investigate age-related differences in DOT sensitivity profiles in individuals aged from 2 to 34 years with narrow age ranges of 0.5 or 1 year.

Approach: We implemented …

KH-type splicing regulatory protein (KHSRP) regulates levels of several neuronal mRNAs linked to nervous system development and function.

The KH-type splicing regulatory protein (KHSRP) is an RNA-binding protein linked to decay of mRNAs with AU-rich elements. KHSRP was previously shown to destabilize Gap43 mRNA and decrease neurite growth in cultured embryonic neurons. Here, we have tested functions of KHSRP in vivo. We find upregulation of 1460 mRNAs in neocortex of adult Khsrp(-/-) mice, of which 527 bind to KHSRP with high specificity. These KHSRP targets are involved in pathways for neuronal morphology, axon guidance, neurotransmission and long-term memory. Khsrp(-/-) mice …

Effect Of Behavioural Practice Targeted At The Motor Action Selection Network After Stroke, Jill C. Stewart, Jessica F. Baird, Stacy L. Fritz, Julius Fridriksson Ph.D.

Motor action selection engages a network of frontal and parietal brain regions. After stroke, individuals activate a similar network, however, activation is higher, especially in the contralesional hemisphere. The current study examined the effect of practice on action selection performance and brain activation after stroke. Sixteen individuals with chronic stroke (Upper Extremity Fugl–Meyer motor score range: 18–61) moved a joystick with the more-impaired hand in two conditions: Select (externally cued choice; move right or left based on an abstract rule) and Execute (simple response; move same direction every trial). On Day 1, reaction time (RT) was longer in Select compared …

Creditors’ Rights In Property Subject To A Beneficiary’S Right Of Withdrawal, S. Alan Medlin, F. Ladson Boyle

Faculty Publications

Estate plans often give trust beneficiaries powers of withdrawal for both tax and nontax reasons. For tax reasons, these powers of withdrawal are typically limited, such as a “five or five power” or a so-called Crummey power commonly pegged to the annual gift tax exclusion amount. A central issue with limited powers of with-drawal is the right of a beneficiary’s creditor to reach trust property subject to the beneficiary’s power to withdraw. Recent uniform statutes, such as the Uniform Trust Code and the Uniform Power of Appointment Act, as well as the Restatement (Third) of Trusts, provide guidance. This Article …

Differentiating Pleistocene Alloformations In The South Carolina Coastal Plain Through Lithologic, Textural, Mineralogical, And Cluster Analyses, Charles Andrew Wykel

Theses and Dissertations

Currently, there is no textural or mineralogic basis for identifying and differentiating Pleistocene strand deposits in the South Carolina (SC) Lower Coastal Plain (LCP). Historically, geologic mapping of the SC coastal plain uses geomorphologic and biostratigraphic techniques for identifying and mapping LCP surficial strand deposits. While useful, both approaches have problems. The aim of this study is to develop a cost-effective approach to differentiate and identify strand deposits of different Pleistocene alloformations occurring in the SC LCP. To accomplish this task, four strand samples were taken from the Ten Mile Hill, the Ladson, and Wicomico alloformations in Horry County, SC. …

The Use Of A Clinical Pathway To Increase Child Abuse Screenings Of Young Children With Fractures, Stephanie Li Schaller

Doctor of Nursing Practice Scholarly Projects

Problem Statement: Nationally, infants and young children who present to emergency departments with fractures are not being screened adequately for possible physical abuse with a skeletal survey (Paine & Wood, 2018; Shelmerdine et al., 2014; Wood et al., 2019). Without universal screenings, implicit bias along racial and socioeconomic lines becomes a factor in deciding which children with fractures get screened, resulting in either under-or over-utilization of skeletal survey screenings (Kim et al., 2017; Paine & Wood, 2018). When child abuse is not diagnosed correctly, further abusive injuries or death can occur (Ravischandiran et al., 2010). Purpose: This evidence-based practice project …

Methods: A pretest and posttest intervention design was utilized to determine the outcomes of this study. The setting …

Understanding The Unseen: Invisible Disabilities In The Workplace, Ann Abney, Veronica Denison, Chris Tanguay, Michelle Ganz

Faculty and Staff Publications

Approximately 61 million (or 1 in 4) adults in the United States have a disability. Despite this prevalence, many people cannot name a coworker who is disabled, possibly due to the number of people who have invisible disabilities. This lack of understanding of both causes and prevalence can cause both the disabled and their supervisors or managers to be unaware of how to address a disabled person’s needs. In this article, the authors shed light on how to improve the professional environment for disabled archivists, staff, and patrons. People without disabilities or those with unrealized disabilities can all benefit when …

Climate Change Compliance, Susan S. Kuo, Benjamin Means

Faculty Publications

Unless corporations prioritize climate change mitigation, efforts to control global warming will fail. Yet, the strategies that have been proposed for enlisting corporations are insufficient to the task. In our era of political polarization, a comprehensive “Green New Deal” to transition the U.S. economy away from fossil fuels is a nonstarter. Nor can we expect corporate risk management or social responsibility to fill the gap; there are practical limits to how far corporate managers can depart from strategies designed to maximize profits for investors.

This Article contends that climate change is a compliance issue. Scholars have overlooked compliance as a …

Molecular Theoretical Model For Lipid Bilayers: Adsorption Of Lipidated Proteins On Lipid Bilayers As A Function Of Bilayer Composition And Curvature, Shauna Celeste Kennard

Theses and Dissertations

Protein localization on biological membranes is motivated by either highly selective recognition of specific target membrane components or nonspecific attraction to general physical properties of the membrane, such as charge, lipid heterogeneity, and curvature. Here we discuss the interaction between lipidated proteins and lipid bilayer membranes from a comprehensive examination of how features of the membrane and its lipid constituents, including lipid composition, headgroup size, degree of tail saturation, tail length (bilayer thickness), and membrane geometry, affect the adsorption ability of the proteins. Of key importance is the strong interconnection among these compositional and morphological elements of the membrane in …
