District Within A District: De Facto Segregation And White Flight Into And Out Of The School District Of University City (1967-1991), Carlos Javier Diaz-Granados

Dissertations

This auto-ethnographic study explores the impetus behind racial transition in the school district of University City between 1967 and 1991. Factors contributing to the exodus of White families and the influx of Black families are examined through a lens of Critical Race Theory. Exclusively White through the mid 1960’s, The School District of University City was nearly 80% Black by the mid 1980’s. A great deal of this transition was related directly to neighborhood patterns occurring in and around the community. Extensive research for this study utilized the oral histories of former students, parents, staff members, board members, and community …

Impact Of The Serotonin Transporter Polymorphism On Emotion Identification In Healthy Older Adults, Staci Erin Scott

Dissertations

Older adults exhibit reduced accuracy and efficiency for identifying facial emotion expressions yet it is unclear how genetic or cognitive variables influence these findings. This study examined the impact of serotonin transporter polymorphism 5-HTTLPR on patterns of explicit emotion identification accuracy and reaction time (RT) in healthy older adults. The impact of 5-HTTLPR on measures of processing speed, attention, and executive function as well as correlations between cognitive measures and emotion identification measures were also examined. Methods: Forty-one individuals over the age of 50 were genotyped for bi-allelic and tri-allelic variants of 5-HTTLPR and administered an emotion recognition paradigm and …

A New Species And Synonymy Of The Neotropical Eucelatoria Townsend And Redescription Of Myiodoriops Townsend, Diego J. Inclán, John O. Stireman Iii

Biological Sciences Faculty Publications

The New World tropics represents the most diverse region for tachinid parasitoids (Diptera: Tachinidae), but it also contains the most narrowly defined, and possibly the most confusing, tachinid genera of any biogeographic region. This over-splitting of genera and taxonomic confusion has limited progress toward our understanding the family in this region and much work is needed to revise, redefine, and make sense of the profusion of finely split taxa. In a recent analysis of the Neotropical genus Erythromelana Townsend, two species previously assigned to this genus, Euptilodegeeria obumbrata (Wulp) and Myiodoriops marginalis Townsend were reinstated as monotypic genera. In the …

Dynamics Of Propagation Of Premature Impulses In Structurally Remodeled Infarcted Myocardium: A Computational Analysis, Candido Cabo

Publications and Research

Initiation of cardiac arrhythmias typically follows one or more premature impulses either occurring spontaneously or applied externally. In this study, we characterize the dynamics of propagation of single (S2) and double premature impulses (S3), and the mechanisms of block of premature impulses at structural heterogeneities caused by remodeling of gap junctional conductance (Gj) in infarcted myocardium. Using a sub-cellular computer model of infarcted tissue, we found that |INa,max|, prematurity (coupling interval with the previous impulse), and conduction velocity (CV) of premature impulses change dynamically as they propagate away from the site of initiation. There are fundamental differences between the dynamics …

Evidence For (And Against) Progenitor Bias In The Size Growth Of Compact Red Galaxies, Stephanie K. Keating, Roberto G. Abraham, Ricardo Schiavon, Genevieve Graves, Ivana Damjanov, Renbin Yan, Jeffrey Newman, Luc Simard

Physics and Astronomy Faculty Publications

Most massive, passive galaxies are compact at high redshifts, but similarly compact massive galaxies are rare in the local universe. The most common interpretation of this phenomenon is that massive galaxies have grown in size by a factor of about five since redshift z = 2. An alternative explanation is that recently quenched massive galaxies are larger (a "progenitor bias"). In this paper, we explore the importance of progenitor bias by looking for systematic differences in the stellar populations of compact early-type galaxies in the DEEP2 survey as a function of size. Our analysis is based on applying the statistical …

Contributions Of Unique Active Site Residues Of Eukaryotic Udp-Galactopyranose Mutases To Substrate Recognition And Active Site Dynamics, Isabel Da Fonseca, Insaf A. Qureshi, Ritcha Mehra-Chaudhary, Karina Kizjakina, John J. Tanner, Pablo Sobrado

Chemistry Faculty Research & Creative Works

UDP-glucopyranose mutase (UGM) catalyzes the interconversion between UDP-galactopyranose and UDP-galactofuranose. Absent in humans, galactofuranose is found in bacterial and fungal cell walls and is a cell surface virulence factor in protozoan parasites. For these reasons, UGMs are targets for drug discovery. Here, we report a mutagenesis and structural study of the UGMs from Aspergillus fumigatus and Trypanosoma cruzi focused on active site residues that are conserved in eukaryotic UGMs but are absent or different in bacterial UGMs. Kinetic analysis of the variants F66A, Y104A, Q107A, N207A, and Y317A (A. fumigatus numbering) show decreases in kcat/KM values of 200-1000-fold for the …

Engaging Fyc Students With Quality Work Design, Candace Deal

Master of Arts in Professional Writing Capstones

Students learn at deeper levels when engaged with their work; however, engaging students in writing is one of the biggest challenges all composition teachers face. This qualitative study asked Kennesaw State University students to describe the work in English 1101 and English 1102 that they found meaningful and engaging. The data collected was then aligned with research about engaging students in grades K-12 based on the work of Phillip Schlechty. Results from this study reveal that many of the same engagement qualities identified by Schlechty have application in the FYC classroom for engaging students and improving learning.

Biological And Physiological Condition Of Juvenile California Halibut (Paralichthys Californicus) Exposed To A Contamination Gradient In Mission Bay, Ca, Kevin Stolzenbach

Theses

Contaminated sediments in marine environments have been shown to be good indicators of ecological risk and a means to assess anthropogenic impacts on marine habitats and the animals that inhabit them (Long et al. 1995, Rattner 2009). Estuarine sediments are especially complex media with regard to physical, chemical, and biological characteristics that trap, store, modify and sometimes release contaminants to the biota (Long et al. 1995). Especially vulnerable are animals that are in constant contact with the sediments, such as flatfishes that partially bury themselves for camouflage (Costa et al. 2011). Impacts can be assessed in a number of ways, …

Distributions Of Ice Supersaturation And Ice Crystals From Airborne Observations In Relation To Upper Tropospheric Dynamical Boundaries, Minghui Diao, Jorgen Jensen, Laura Pan, Cameron Homeyer, Shawn Honomichl, James Bresch, Aaron Bansemer, Eric Jensen

Faculty Publications, Meteorology and Climate Science

Cirrus clouds are one of the largest sources of uncertainties in predicting future climate. Ice nucleation and ice crystal growth inside cirrus clouds require ice supersaturation (ISS). Previously, remote sensing observations have shown that the locations of cirrus clouds’ cloud top height are highly correlated with the thermal tropopause height (Pan and Munchak, 2011). However, it is unclear if the initial conditions of cirrus clouds – ice supersaturated region (ISSRs) – have similar features in the extratropical upper troposphere and lower stratosphere (UT/LS). In fact, the dynamical processes and conditions that contribute to ISS formation from the microscale (~100 m) …

Women In Kazakhstan: A Multifaceted Approach To Female Political Representation, Ashley Gaile Benedict

Dissertations

This investigation focuses on two competing theories (historical institutionalism and social constructivism) and their explanatory value in regards to female political representation in Kazakhstan. Historical Institutionalism maintains that current institutional dynamics are constrained by past institutional formations, even when these past institutions are no longer relevant. Social Constructivism challenges this theory by upholding that institutions are culturally situated and a reflection of shared ideas rather than material forces as argued by historical institutionalism. Based on Hanna Pitkin’s (1967) four dimensions of representation (formal, descriptive, substantive, and symbolic), I examine how Kazakhstan’s Soviet past and its creation of a Kazakh ethnic-national …

A Representation Of Robotic Behaviors Using Component Port Arbitration, A Paikan, G Metta, L Natale

School of Engineering, Computing and Mathematics

Developing applications considering reactiveness, scalability and re-usability has always been at the center of attention of robotic researchers. Behavior-based architectures have been proposed as a programming paradigm to develop robust and complex behaviors as integration of simpler modules whose activities are directly modulated by sensory feedback or input from other models. The design of behavior based systems, however, becomes increasingly difficult as the complexity of the application grows. This article proposes an approach for modeling and coordinating behaviors in distributed architectures based on port arbitration which clearly separates representation of the behaviors from the composition of the software components. Therefore, …

A More Efficient Nonparametric Test Of Symmetry Based On Overlapping Coefficient, Hani M. Samawi, Robert L. Vogel

Biostatistics: Faculty Publications

In this paper we provide a more efficient nonparametric test of symmetry based on the empirical overlap coefficient using kernel density estimation applied to an extreme order statistics, namely extreme ranked set sampling. Our simulation investigation reveals that our proposed test of symmetry is at least as powerful as currently available tests of symmetry. Intensive simulation is conducted to examine the power of the proposed test. An illustration is provided using cardiac output and body weight of neonates in a neonatal intensive care unit.

Class-Based Interference Management In Wireless Networks, Mohammad Arif Hossain, Mostafa Zaman Chowdhury, Shakil Ahmed, Yeong Min Jang

Electrical and Computer Engineering Student Research

Technological advancement has brought revolutionary change in the converged wireless networks. Due to the existence of different types of traffic, provisioning of Quality of Service (QoS) becomes a challenge in the wireless networks. In case of a congested network, resource allocation has emerged as an effective way to provide the excessive users with desirable QoS. Since QoS for non-real-time traffic are not as strict as for real-time traffic, the unoccupied channels of the adjacent cells can be assigned to the non-real-time traffic to retain QoS for real-time traffic. This results in the intensified bandwidth utilization as well as less interference …

Geochemistry Of Mineral Dust In The Mcmurdo Dry Valleys Region, Antarctica, Kelly M. Deuerling, Ethan Baxter, Jeremy Inglis, William Berry Lyons

Geography and Geology Faculty Proceedings & Presentations

The transport and deposition of windblown materials are major processes in the ice-free areas of polar regions. The deposition of aeolian material provides connectivity within the ecosystems of these regions and is integral in understanding geochemical balances and exchanges between landscape units. We have analyzed materials deposited on glacier and permanent lake-ice surfaces as well as geomorphological features formed by aeolian processes in the largest ice-free area in Antarctica, the McMurdo Dry Valleys (~78 °S) in order to determine the source of this sediment. This presentation will focus on the materials collected from the glacier and lake surfaces. The bulk …

Poly-3-Hexylthiophene Nanorods As A Donor For Organic Photovoltaics, Dharmesh Patel

Mahurin Honors College Capstone Experience/Thesis Projects

Poly-3-hexylthiophene functionalized silsesquioxane nanorods (P3HT-NRs) were prepared by direct hydrolysis and condensation of P3HT-silane precursor using the modified Stöber method. The silane precursor was stirred in a mixture of two solvents in the presence of a base under room temperature for three different reaction times. The size, shape, and morphology of these novel nanostructures were visualized using the transmission electron microscope (TEM) and scanning electron microscope (SEM). The composition of the P3HT-NRs was confirmed by FTIR and its silane by proton NMR. Future work will focus on evaluating photovoltaic performance of these nanorods as a donor for organic photovoltaics.

A Case Study Of Internationalization At Western Kentucky University, Minh Dao

Mahurin Honors College Capstone Experience/Thesis Projects

The study investigates the student levels of satisfaction and engagement with internationalization at Western Kentucky University (WKU). This study surveyed 418 undergraduate students (84.50% domestic and 15.50% international students) on WKU’s main campus to examine how students perceive and interact with various components of the institution-wide internationalization efforts: international-related curriculum and extra-curricular activities, presence of international students and faculty, study abroad opportunities and cross-cultural friendships. Statistical methods were used to analyze student responses. Research findings show that students are more satisfied with international efforts at home when faculty actively engages in promoting international learning in the classroom. Furthermore, students who …
