Investigating Disparities And Safety Equity In Pedestrian Nighttime Crashes In Michigan, Sia Isaria Mwende

Masters Theses

For the past eleven years (2011 - 2021) in Michigan, 76 percent of all fatal pedestrian crashes occurred at night. Over the same period, about 36 percent of pedestrian nighttime crashes were fatal or incapacitating (KA), while only 25 percent of daytime pedestrian crashes were fatal or incapacitating (KA). Previous studies suggest that, overall, poor neighborhoods and racial minorities are associated with more pedestrian crashes. With more fatal and incapacitating pedestrian crashes occurring at night, it is imperative to examine how these crashes are distributed by economic status and racial makeup. Therefore, this study aims to investigate the racial and …

Leadership Identity Development Among Aspiring Women Leaders In Higher Education: A Phenomenological Study Of Formal Mentoring, Malia E. Roberts

Dissertations

Men have held the majority of presidencies, vice-presidencies, deanships, and other top administrative positions on college campuses since 1950 (Parker, 2015). The disproportionately low representation of women holding leadership roles in higher education is even more urgent considering few women ever reach the senior most leadership levels (Hannum et al., 2015). As such, the American Council on Education not only identified the need to increase the presence of women in leadership positions and to cultivate a pipeline of future leaders, but also the need to provide formal leadership training opportunities for women (Howard & Gagliardi, 2018). While various higher education …

Using The Lens Of Flourishing To Understand The Professional Well-Being Of K-12 Teachers Who Have Worked In Urban Schools For Over A Decade, Candis M. Thomas

Dissertations

Historically, urban public schools with high concentrations of high-poverty, low-achieving students, report having difficulty attracting, developing, and retaining qualified and effective teachers (Ansley et al, 2019; Petty et.al, 2012; Simon & Johnson, 2015; Wilder, 2012). A common explanation to the attrition crisis in urban schools is that teachers are suffering from stressors (e.g., student characteristics, school climate, concerns for safety, lack of parental support, accountability measures), that leaves them burnt out. Yet, there are experienced and qualified K-12 teachers who are committed to working in these schools. Advances in the field of positive psychology, has spilled over into the educational …

Learning Finite Mixture Of Ising Graphical Models, Chong Gu

Dissertations

The Ising model is valuable in examining complex interactions within a system, but its estimation is challenging. In this work, we proposed penalized likelihood procedures to infer conditional dependence structure when observed data come from heterogeneous resources in high-dimensional setting. The proposed method can be efficiently implemented by taking advantage of coordinate-ascent, minorization–maximization principles and EM algorithm. A BIC-type criterion will be utilized for the selection of the tuning parameter in the penalized likelihood approaches. The effectiveness of the proposed method is supported by simulation studies and a real-world example.

Evaluation Of A Classroom Management Video Training Package, Avner Fraidlin

As a part of such efforts, this dissertation proposes Functional Generalized Linear Mixed Model (FGLMM), which extends classical generalized linear mixed models to include functional covariates. Functional Data Analysis (FDA) is a rapidly developing area of statistics for data which can be naturally viewed as smooth …

Evaluating The Performance Of Estimators In Sem And Irt With Ordinal Variables, Bo Klauth

Dissertations

In conducting confirmatory factor analysis with ordered response items, the literature suggests that when the number of responses is five and item skewness (IS) is approximately normal, researchers can employ maximum likelihood with robust standard errors (MLR). However, MLR can yield biased factor loadings (FL) and FL standard errors (FLSE) when the variables are ordinal. Other estimators are available. Unweighted least squares and weighted least squares with adjusted mean and variance (ULSMV and WLSMV) are known as the estimators for CFA with ordinal variables (CFA-OV). Another estimator, marginal maximum likelihood (MML), is used in the item response theory (IRT), specifically …

Nonparametric Tests For Replicated Latin Squares, Joseph Yang

Dissertations

Two classes of nonparametric procedures for a replicated Latin square design that test for both general and increasing alternatives are developed. The two classes of procedures are similar in the sense that both transform the data so that existing well-known tests for randomized complete block designs can be utilized. On the other hand, the two classes differ in the way that the data is transformed - one class essentially aggregates the data while the other class aligns the data. Within these contexts, the exact distributions and asymptotic distributions are discussed, when applicable. The exact distributions are easily computed using the …

Side-Stepping God: How The Nonreligious Find Success In Alcoholics Anonymous, Caitlin Trombley

Dissertations

This dissertation utilized mixed methods research to examine how nonreligious individuals with substance use disorders navigate recovery within—or in spite of—Alcoholics Anonymous (AA). Both the 12-step program itself and Alcoholics Anonymous have long been criticized for being religious and/or spiritual in nature, and some studies have shown that this is particularly challenging for nonreligious individuals seeking recovery. The purpose of this research was to (a) identify differences in recovery resources (recovery capital) between the religious, the nonreligious, those in AA, and those who have adopted alternative forms of recovery; (b) identify barriers that the nonreligious face as they navigate recovery …

Prospective Mathematics Teachers’ Technological Pedagogical Content Knowledge In Pieces, Nicholas Eric Witt

Dissertations

Productively integrating technology is a vitally important part of teachers’ practice (Barlow, 2021; Bezuk et al., 2017; NCTM, 2018). To adequately prepare Prospective Mathematics Teachers (PMTs) for the demands of teaching professionally, we need to understand more about how teachers and PMTs learn to integrate technology into their classroom. Some models exist related to teachers’ knowledge of integrating technology (e.g., Mishra & Koehler, 2006; Rocha, 2020). However, these models do little to conceptualize the knowledge resources that are activated in the moment of designing technologically-enhanced, conceptually-oriented mathematics tasks. This dissertation draws on ideas from the Knowledge in Pieces (KiP) (diSessa, …

Characterization Of Shinella 6-Hydroxy-(L)-Nicotine Oxidase (6hlno-Se), Kaitrin Funckes

Honors Theses

6-hydroxy-(L)-nicotine oxidase, isolated from the organism Shinella sp. HZN7 (6HLNO-SE), is an enzyme that during the catabolism of nicotine catalyzes the oxidation of (S)-6-hydroxynicotine to 6-hydroxypseudeooxynicotine. This enzyme is a member of the monoamine oxidase (MAO) structural family of flavoproteins, which contain a highly conserved FAD-binding domain. Within the binding domain is a conserved lysine residue that can be traced throughout evolutionary history in this family. 6HLNO isolated from Arthrobacter nicotinovorans serves as a model enzyme for the one isolated from Shinella as both catalyze the same reaction in this biochemical pathway and much has been studied about the Arthrobacter …
