Development Of The Mentalizing Network Structures And Theory Of Mind In Extremely Preterm Youth, Xiaoxue Fu Ph.D., Andy Hung, Aryanne D. De Silva, Tyler Busch, Whitney I. Mattson, Kristen R. Hoskinson, Hudson Gerry, Eric E. Nelson

Faculty Publications

Adolescents born preterm (<37 weeks of gestation) are at elevated risk for deficits in social cognition and peer relationships. Theory of Mind (ToM) is a complex form of social cognition important for regulating social interactions. ToM and the underlying mentalizing network continue to develop across adolescence. The present study recruited 48 adolescents (12–17 years old) who were either born extremely preterm (EPT; <28 weeks of gestation) or full-term (FT) at birth. Cortical thickness, gray matter volume and surface area were measured in four regions of the mentalizing network: the temporoparietal junction, anterior temporal cortex, posterior superior temporal sulcus and frontal pole (mBA10). We also assessed the adolescents’ performance on a ToM task. Findings revealed both group differences and group-by-age interaction effects in the gray matter indices within the temporal lobe regions of the mentalizing network. The EPT group also performed significantly worse than the FT group on the ToM task. The cortical structural measures that discriminated the EPT and FT groups were not related to ToM performance. These results highlight altered developmental changes in brain regions underlying mentalizing functions in EPT adolescents relative to FT controls.

The Formal Institutional Context Of Informal Entrepreneurship: A Cross-National, Configurational-Based Perspective, Joshua K. Ault, Andrew Spicer

Faculty Publications

While previous comparative research has identified the formal institutional conditions that differentiate countries on their degree of informal entrepreneurship, this paper examines the characteristics that shape cross-national diversity in its type. Based on a series of fuzzy-set qualitative comparative analyses (fs/QCA) of 138 country cases, we find evidence of causal heterogeneity in the configuration of institutional conditions associated with entrepreneurial outcomes that are informal and growth-oriented and those that are informal and subsistence-oriented. Given our results, we propose that the formal institutional-based conditions that differentiate between types of informal sectors are best identified by the conjoint mixture of strength and …

Event-Triggered Optimal Adaptive Control Of Partially Unknown Linear Continuous-Time Systems With State Delay, Rohollah Moghadam, Vignesh Narayanan, Sarangapani Jagannathan

Publications

This paper proposes an event-triggered optimal adaptive output feedback control design approach by utilizing integral reinforcement learning (IRL) for linear time-invariant systems with state delay and uncertain internal dynamics. In the proposed approach, the general optimal control problem is formulated into the game-theoretic framework by treating the event-triggering threshold and the optimal control policy as players. A cost function is defined and a value functional, which includes the delayed system output, is considered. First, by using the value functional and applying stationarity conditions using the Hamiltonian function, the output game delay algebraic Riccati equation (OGDARE) and optimal control policy are …

Use Of Equity-Informed Social Media Covid-19 Risk Communication Tools: A Scoping Review Protocol, Anita Kothari, Nedra Peter, Lorie Donelle Phd, Rn, Fcan

Publications

INTRODUCTION: Health agencies and community organisations play a crucial role in disseminating information to the public about COVID-19 risks and events, providing instructions on how to change behaviour to mitigate those risks, motivating compliance with health directives and addressing false information. Social media platforms are a critical tool in risk communication, providing a medium for rapid transmission of messages as well as providing the opportunity for engagement and immediate feedback. Access to health information, services and support are especially important for marginalised and underserved ('equity-deserving') populations who are disproportionately affected by COVID-19. This scoping review aims to review the breadth …

How To Survive College As An Acoa: The Effectiveness Of University Resources On Helping Acoas Socially And Psychologically Succeed During Their Academic Career, Kelly Buchan

Senior Theses

In 2019, 14.5 million people ages 12 and older had Alcohol Use Disorder (AUD), but only 10% received treatment (National Institute on Alcohol Abuse and Alcoholism [NIAAA], 2022). Parental drinking problems can directly affect children, or “Adult Children of Alcoholics.” Of the few studies targeting ACoAs, results show that ACoAs not only have higher risks of mental illness, but they also have lower GPAs and social health (Schroeder & Kelley, 2008). Thus, this study assessed the extent to which perceptions of the college drinking environment are related to higher depression rates in ACoAs, certain drinking motivations, and reluctance to use …

Applications Of Laser Liftoff Technique For Wide Bandgap Power And Flexible Electronics, Md Didarul Alam

Theses and Dissertations

Wide bandgap (WBG) AlGaN/GaN and ultrawide bandgap (UWBG) AlGaN/AlGaN III-nitride high electron mobility transistors (HEMTs) have come a long way since their initial demonstration and are desired for a multitude of applications in deep-scaled high-frequency, high-voltage, high-current, and high-temperature power electronics. Although AlGaN/GaN HEMTs have recently become state-of-the-art in consumer electronics chargers and amplifiers, the performance of the devices is limited by severe self-heating which significantly reduce their efficacy in demanding applications that require high-current density. One strategy to reduce this self-heating effect in GaN HEMTs is to use high thermal conductivity SiC or bulk AlN substrates. While this approach …

Examining The Influence Of Argument Driven Inquiry Instructional Approach On Female Students Of Color In Sixth Grade Science: Its Impact On Classroom Experience, Interest, And Self-Efficacy In Science, Written Argumentation Skills, And Scientific Voice, Paul Duggan

Theses and Dissertations

Four of the eight Engineering Standards in the Next Generation Science Standards (NGSS, 2013) focus on authentic science communication: “asking questions (science) and defining problems (engineering), analyzing and interpreting data, constructing explanations (for science) and designing solutions (for engineering), engaging in argument from evidence, obtaining, evaluating and communicating information” (Sampson et al., 2010, p. 218). Authentic science communication is supported in NGSS through cross-cutting concepts (Driver et al., 2000) that integrate the structure and function of science concepts together with communication strategies that include reading, writing, and peer critique. These cross-cutting concepts include reading strategies that focus on reading informational …

Implementation Of A Bowel Management Care Bundle On The Spinal Cord Injury Patient Population During Acute Recovery, Jessica Rene Baldwin

Doctor of Nursing Practice Scholarly Projects

Over 17,000 Americans suffer from spinal cord injuries (SCI) annually. Although the loss of motor function is a blatantly obvious sequela, the loss of autonomic nervous system control, and its direct effects on various body systems, is scarcely understood. The most frequently reported impairment associated with SCI-related bowel dysmotility is Neurogenic Bowel Dysfunction (NBD), affecting approximately 20-60% of the SCI population. NBD is defined as slow colonic time and is hallmarked by constipation and often impaction, leading to life-threatening complications, such as bowel obstruction, fecal impaction, autonomic dysreflexia, and even death. Identifying dysmotility within the SCI patient population and early …
