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.

Faculty Publications

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 …

Boys, Reading, And Video Games: A Mixed-Methods Case Study Examining The Effects Of Using A Recreational Video Game To Improve Reading Comprehension Performance At An Elementary School In Texas, Donald Wayne Meyer Jr.

Theses and Dissertations

The fifth-grade boys at an elementary school in Texas consistently perform lower than girls on the State of Texas Assessments of Academic Readiness (STAAR) reading portion. The gender gap in reading is not exclusive to this school. Boys score lower than girls on state-administered reading assessments each year in the United States (U.S.) and have done so for decades (Bozack & Salvaggio, 2013; Clinton et al., 2014; Schwabe et al., 2015; Schwanenflugel & Knapp, 2018). This study explored the effects of using a recreational video game on fifth-grade boys struggling with reading comprehension in a six-week-long reading intervention program.

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 …

Pediatric Patients In Diabetic Ketoacidosis: A Pathway To Improvement, Rebecca Russell Vincent

Doctor of Nursing Practice Scholarly Projects

Problem Statement: Pediatric patients in diabetic ketoacidosis (DKA) frequently present to non-pediatric specific care centers initially for medical management where providers may or may not be familiar with standards and treatment guidelines particular to this specialty population. Purpose: The purpose of this project was to establish a pediatric DKA clinical pathway (CPW). Pediatric patients require precise treatments tailored to age and weight specifications. A pediatric DKA CPW identifies treatment order sets, goals, and outcomes customized to the patient’s metabolic demand. Commonalities within a predictable course of treatment for patients with a shared clinical diagnosis result in accelerated care, improved patient …

Networked Digital Predictive Control For Modular Dc-Dc Converters, Castulo Aaron De La O Pérez

Theses and Dissertations

The concept of power electronics building blocks (PEBB) has driven advancements in highly modularized converter systems with many identical subsystems. PEBBs are distributed subsets of converter systems and thus require communication with a control system for their coordination. For this type of system, the communication latency with hard deterministic deadlines is the driving attribute of communication system requirements. However, inherent communication requirements for PEBB-based converter systems also provide opportunities for coordination of energy flow.

Leveraging developments in Gigabit serial communication channels, a control and communication platform architecture for distributed control schemes based on the 2D-Torus communication network topology was developed …

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 …

Differences In Aggression And Alcohol Use Among Youth With Varying Levels Of Victimization And Popularity Status, Sarah T. Malamut, Molly Dawes, Tessa A.M. Lansu, Yvonne Van Den Berg, Antonius H.N. Cillessen

Faculty Publications

Awareness that high-status adolescents can be targets of aggression has grown in recent years. However, questions remain about the associations of the confluence of victimization and popularity with adjustment. The current study fills this gap by examining the joint and unique effects of victimization and popularity on aggression and alcohol use. Participants were 804 Dutch adolescents (50.2% boys, M_age = 13.65) who were followed for one year. High-status victims were more aggressive and drank more alcohol than lower-status victims. High-status victims were also more proactively and indirectly aggressive and self-reported more bullying than high-status non-victims. Thus, the findings demonstrated …

Distributed Interdigital Capacitor (Idc) Sensing For Cable Insulation Aging And Degradation Detection, Md Nazmul Al Imran

Theses and Dissertations

Nuclear power plants (NPPs) contain myriad power, control, instrumentation, and other types of cables. The polymer insulation and jacket materials of such cables degrade over time due to operation and environmental conditions e.g., heat, humidity, and radiation. Since the life span of NPPs may extend beyond 40-50 years regular monitoring of cable insulation and jacket polymers is critical to ensure safe and reliable operation. The agingrelated degradation of cables causes changes in the relative permittivity or dielectric constant of the insulation and jacket materials. Capacitor sensors, if properly designed and developed can measure this change and thus can provide an …

Using A Multi-Direction Reaching Approach To Investigate Fitts’ Law And The Effect Of Attentional Focus On Motor Learning, Charles R. Smith

Theses and Dissertations

The Index of Difficulty value (ID) derived from Fitts’ Law’s speed-accuracy trade-off is commonly used to determine the difficulty of a targeted reaching movement and balance difficulty in sequence learning tasks. However, this value does not account for the mechanical difficulty of multi-directional movements which could affect both performance and learning. Where we direct our focus when completing a task/skill can also have an effect on how we perform and learn that task, however, the manner in which differing focus instructions affect learning a whole-arm reaching task is relatively unknown. The purpose of this dissertation was to examine 1) how …
