Coevolutionary Methods Enable Robust Design Of Modular Repressors By Reestablishing Intra-Protein Interactions, Xian-Li Jiang, Rey P. Dimas, Clement T.Y. Chan, Faruck Morcos

Biology Faculty Publications and Presentations

enetic sensors with unique combinations of DNA recognition and allosteric response can be created by hybridizing DNA-binding modules (DBMs) and ligand-binding modules (LBMs) from distinct transcriptional repressors. This module swapping approach is limited by incompatibility between DBMs and LBMs from different proteins, due to the loss of critical module-module interactions after hybridization. We determine a design strategy for restoring key interactions between DBMs and LBMs by using a computational model informed by coevolutionary traits in the LacI family. This model predicts the influence of proposed mutations on protein structure and function, quantifying the feasibility of each mutation for rescuing hybrid …

Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs (RDDs) are the most robust quasi-experimental design, but current statistical models are limited to estimates for the simple causal relationship between only two variables: the independent and dependent variables. In practice, intervening variables (or mediators) are often observed as part of the causal chain. Mediators explain the why and how a treatment or intervention works. Therefore, mediation and RDD analysis combined can be a useful tool in identifying key components or processes that make intervention programs effective while making causal inferences for improving student achievement, despite natural constraints, limitations, and ethical considerations. Without an integrated framework of …

An Analysis Of Performance-Based Funding Policies At An Open Access Institution, John Brady

Electronic Theses and Dissertations, 2020-2023

Performance-based funding policies have become popular among state legislators seeking ways to hold public higher education institutions accountable. Approximately 30 states currently use performance-based funding policies to tie state appropriations to institutional outcomes according to a defined set of metrics. Despite the popularity of the policy approach, very little empirical evidence exists to suggest that performance-based funding is effective in producing the often-intended outcomes of increased student retention and degree attainment rates. Numerous studies have indicated that these policies may produce unintended outcomes including the restriction of access, the gaming of performance-based funding systems, and the widening of equity gaps. …

Boilerplate Collusion: Clause Aggregation, Antitrust Law, & Contract Governance, Orly Lobel

Minnesota Law Review Vols. 106:2 onward (2021-present)

Contract clauses should be assessed in relation to each other when examining their meaning, validity, and enforcement. In contemporary markets, drafters create impenetrable bundles of clauses and sets of interrelated contracts operating together. This Article exposes the ways that a contract is larger than the sum of its separate clauses and a set of interrelated contracts is more harmful than the aggregation of each contract on its own. The Article further shows that contract adjudication embeds these insights intuitively, but both contract law and antitrust law have yet to develop a principled and consistent analysis of how contract clauses collude …

An Exploratory Investigation Of Grit And Its Relationship To Student Integration In Athletic Training Education Programs, Carlos Gual

Electronic Theses and Dissertations, 2020-2023

Students must enroll in rigorous accredited academic programs and pass the National Board of Certification (BOC) examination to become athletic trainers. Therefore, studies in athletic training and student achievement focus on student persistence/retention and BOC Examination pass rates. The majority of studies conclude that cognitive measures like grade point average (GPA) have a relationship with both retention and exam pass rates. However, research should also consider meta-cognitive factors (i.e., personality traits). The purpose of this study was to examine the relationship between athletic training students' grit (a metacognitive factor) and their academic, clinical, and social integration. The population for this …

Electronic Theses and Dissertations, 2020-2023

"With so many students working, and such large numbers devoting a considerable amount of time to one or more jobs, work is – after going to class- the most common activity in which undergraduates engage" (Kuh, 2018, p. ix). An under-researched factor to investigate why students retain, is participation in an on-campus student employment program. The purpose of the study is to explore the relationship between a student's participation in student employment and if the student retains from their first to second year. Understanding this relationship can provide an opportunity to create positive impact for both the student and institution …

Acoustoelectric Amplification In Piezoelectric-Silicon Micromachined Lamb Wave Devices, Hakhamanesh Mansoorzare

Electronic Theses and Dissertations, 2020-2023

In this dissertation, heterostructured micro-acoustic devices are explored that leverage the interactions between acoustic phonons and electrons to enable radio frequency (RF) signal amplification or attenuation. Thin films of piezoelectric and semiconductor material are tailored into a heterostructure that allows for a strong acoustoelectric (AE) effect due to the combination of high electromechanical coupling and high electron drift velocity in said films respectively. In such devices, the relative electron drift and acoustic velocities could determine whether the RF signal undergoes AE gain or loss, rendering the device non-reciprocal. This is a highly sought-after property for building isolators and circulators which …
