Blacks' Intergenerational Trauma Triggered By Police Misconduct, Anselma Johnayala

Doctoral Dissertations and Projects

A plethora of studies on intergenerational trauma and a nascent body of studies regarding policing are amalgamated in this phenomenological research approach. This phenomenological study aimed to understand the adverse experiences of Black individuals’ interactions with law enforcement and how these involvements contribute to the transmission of trauma. The intergenerational trauma of Blacks’ experiences could be processed through Critical Race Theory (CRT), Personal Construct Theory (PCT), and Bowen’s Multigenerational Family Systems Theory (BMFST). Each theory explains the relationship between a person’s experiences, the generational response and functioning, and the existence of racial bias as proliferated in the oppression of one …

The Impact Of Social Emotional Beliefs On Teachers' Self-Efficacy: A Correlative Study, Amber Davis

Doctoral Dissertations and Projects

The purpose of this quantitative, corelative study was to determine if Social Emotional Learning (SEL) beliefs had an impact on teacher self-efficacy amongst teachers within a suburban school district population. Social Emotional Learning programs aim to address students’ negative social and emotional concerns. These negative social and emotional concerns amongst students also have a negative impact on teachers. This study served to educate and provide school level administration data on whether SEL beliefs impact educator self-efficacy. This investigation can guide school districts on developing appropriate and targeted professional development for specific subgroups of teachers. For this study, a sample of …

Employee Engagement In Public Sector Organizations, Rhonda Isler Dent

Doctoral Dissertations and Projects

Public Administrators recognize Employee Engagement (EE) as a significant component in fostering effective work environments in public sector organizations. EE is a recently established concept on Public Administration's agenda and the mantra for today's workplace, leading organizations to recognize the vested interest in measuring, observing, and increasing employee performance. Evidence suggests EE is vital to an organization's thriving in a competitive global market. The research study evaluated and measured the influences that affect EE in public-sector organizations. A quantitative method using the quasi-experimental design was used to answer the research question and address the corresponding hypotheses. The researcher used the …

Birkhoff Summation Of Irrational Rotations: A Surprising Result For The Golden Mean, Heather Moore

University Honors Theses

This thesis presents a surprising result that the difference in certain sums of constant rotations by the golden mean approaches exactly 1/5. Specifically, we focus on the Birkhoff sums of these rotations, with the number of terms equal to squared Fibonacci numbers. The proof relies on the properties of continued fraction approximants, Vajda's identity and the explicit formula for the Fibonacci numbers.

Ex-Vivo Hippocampus Segmentation Using Diffusion-Weighted Mri, Haoteng Tang, Siyuan Dai, Eric M. Zou, Guodong Liu, Ryan Ahearn, Ryan Krafty, Michel Modo, Liang Zhan

Computer Science Faculty Publications

The hippocampus is a crucial brain structure involved in memory formation, spatial navigation, emotional regulation, and learning. An accurate MRI image segmentation of the human hippocampus plays an important role in multiple neuro-imaging research and clinical practice, such as diagnosing neurological diseases and guiding surgical interventions. While most hippocampus segmentation studies focus on using T1-weighted or T2-weighted MRI scans, we explore the use of diffusion-weighted MRI (dMRI), which offers unique insights into the microstructural properties of the hippocampus. Particularly, we utilize various anisotropy measures derived from diffusion MRI (dMRI), including fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity, for …

The Impact Of Data Preparation And Model Complexity On The Natural Language Classification Of Chinese News Headlines, Torrey J. Wagner, Dennis Guhl, Brent T. Langhals

Faculty Publications

Given the emergence of China as a political and economic power in the 21st century, there is increased interest in analyzing Chinese news articles to better understand developing trends in China. Because of the volume of the material, automating the categorization of Chinese-language news articles by headline text or titles can be an effective way to sort the articles into categories for efficient review. A 383,000-headline dataset labeled with 15 categories from the Toutiao website was evaluated via natural language processing to predict topic categories. The influence of six data preparation variations on the predictive accuracy of four algorithms was …

Library/Life Sciences Undergraduate Poster Competition 2024

In population demographics, each population has an age stage vital rate (fecundity and survival) in its life history that has the greatest influence on the asymptotic population growth rate, λ.

American black bears (Ursus americanus) are found throughout North America. Other studies on population demographics have focused on populations in higher resource availability areas but none in semiarid environments where resource scarcity is a result of the variable climate.

Objective

Our objective was to determine if factors influencing population dynamics of black bears in semi-arid environments were similar to factors affecting population dynamics in mesic environments where …

A Rare Plant In Peril: Conservation Concerns For An Endemic Alpine Plant, Ipomopsis Spicata Ssp Tridactyla, Kainoa Bolinder, Loreen Allphin, Madison Huie, Steven Flinders

Library/Life Sciences Undergraduate Poster Competition 2024

Ipomopsis spicata ssp. tridactyla, (I. tridactyla or IPTR; Fig. 2 & 12), is a rare alpine plant species endemic to the Tushar Mountains and Markagunt Plateau of southern Utah. There is limited knowledge available about population dynamics and community composition. Due to difficult abiotic conditions, alpine environments are more vulnerable to lasting damage from disturbance (Scherrer & Pickering, 2005). Ipomopsis tridactyla is listed as high-priority for conservation (Alexander, 2016). As conservation concerns for alpine plant communities increase due to climate change (Kopp & Cleland, 2013), so does the need for long-term monitoring of plant populations. Thus, we set …

Quantitative Shotgun Proteomic Analysis Of Bacteria After Overexpression Of Recombinant Spider Miniature Spidroin, Masp1, Kathryn Randene, J. Alexander H. Mendoza, Michael Ysit, Craig Vierra

Pacific Faculty Work

Spider silk has extraordinary mechanical properties, displaying high tensile strength, elasticity, and toughness. Given the high performance of natural fibers, one of the long-term goals of the silk community is to manufacture large-scale synthetic spider silk. This process requires vast quantities of recombinant proteins for wet-spinning applications. Attempts to synthesize large amounts of native size recombinant spidroins in diverse cell types have been unsuccessful. In these studies, we design and express recombinant miniature black widow MaSp1 spidroins in bacteria that incorporate the N-terminal and C-terminal domain (NTD and CTD), along with varying numbers of codon-optimized internal block repeats. Following spidroin …

The Homotopy Cardinality Of The Representation Category, Justin Murray

LSU Doctoral Dissertations

Given a Legendrian knot in (R^3, ker(dz − ydx)) one can assign a combinatorial invariants called ruling polynomials. These invariants have been shown to recover not only a (normalized) count of augmentations but are also closely related to a categorical count of augmentations in the form of the homotopy cardinality of the augmentation category. In this article, we prove that that the homotopy cardinality of the n-dimensional represen- tation category is a multiple of the n-colored ruling polynomial. Along the way, we establish that two n-dimensional representations are equivalent in the representation category if they are “conjugate homotopic”. We also …

The Return Of Three-Judge Constitutional Courts, Matt Queen

Duke Law Journal

State courts wield the authority to elevate state constitutional protections above those afforded by the U.S. Constitution. That power is great—so great that some legislatures have intervened in constitutional adjudication, purportedly to undermine forum shopping and check a single judge’s influence. Accordingly, North Carolina and Tennessee require that three-judge trial courts hear constitutional challenges to state laws. These courts echo twentieth-century congressional efforts to trim federal courts’ equitable jurisdiction. They also present new and familiar drawbacks spawned by their federal ancestors.

This Note examines these new constitutional courts through several lenses: their historical context, political development, advantages, and drawbacks. Although …

The Gyrokinetic Dispersion Relation Of Microtearing Modes In Collisionless Toroidal Plasmas, Benjamin D G Chandran, A A. Schekochihin

Faculty Publications

We solve the linearized gyrokinetic equation, quasineutrality condition and Ampere's law to obtain the dispersion relation of microtearing modes (MTMs) in collisionless low- $\beta$ toroidal plasmas. Consistent with past studies, we find that MTMs are driven unstable by the electron temperature gradient and that this instability drive is mediated by magnetic drifts. The dispersion relation that we derive can be evaluated numerically very quickly and may prove useful for devising strategies to mitigate MTM instability in fusion devices.

Closing The Gap Between Theory And Practice To Promote Equity In Stem: Coaching Teachers With Udl Strategies To Empower Students, Debbie Langone

Theses & Dissertations

U.S. schools have witnessed educational reforms that have shifted science curriculum and pedagogy within classrooms. Yet, all these reforms have failed to reduce the racial and gender gaps in STEM fields. In 2016, New York State implemented the New York State Science Learning Standards (NYSSLS) to address these gaps. Problems remain, however, with the NYSSLS standards. The NYSSLS do not offer teachers pedagogical practices with regards to implementation. Students are expected to engage in practices as they emulate scientists, without any direction for teachers to support students through these practices, and they exemplify a deficit mindset by placing the blame …
