Creating Equitable Educational Experiences for African American Males through Advanced Academics
Across the United States, African American males face barriers to securing a quality education. Barriers such as educational gatekeeping, and low identification, have caused African American males' enrollment in advanced placement courses to be at a rate lower than all other ethnicity and gender populations. A qualitative approach to research was used to explore how and in what ways district and school leaders created or hindered equitable advanced academic program opportunities for African American males. Through the lens of critical social theory, individual face-to-face interviews with district/campus educators and a focus group interview with African American male students, the lived experiences of participants within the advanced placement program were brought to the fore. Three questions guided the study: 1) How do district and school policies and practices create equitable advanced academic program opportunities for African American males; 2) How and in what ways do district and school leaders create or hinder equitable advanced academic program opportunities for African American males; and 3) What conditions have supported or hindered African American males in their ability to enroll and succeed in advanced academic courses. Findings revealed four themes to creating equity for African American males within the advanced placement program which included, …

Creeks and Open Spaces: Ned Fritz's Environmental Crusades
Edward C. Fritz was one of the most influential environmentalists in Texas history. Although he took a circuitous route to environmental activism, Fritz evolved into a powerful force fighting on behalf of Texan nature. Participating in substantial actions throughout the second half of the twentieth century, Fritz's contributions to environmental activism resulted in the successful preservation of thousands of acres and multiple wildlife species. Fritz parlayed his legal background into effective activism, beginning his career with a successful lobbying campaign for protection of Harris Hawks. He led the campaign to stop a decades old plan for canalization of the Trinity River. The creation of COST combined Fritz's environmental focus with the concerns of economic conservatives to prevent a billion dollar government funded project that would have significantly altered the river. Fritz then led a cadre who took over efforts to establish a preserve in the Big Thicket national forest. He oversaw the foundation of a protected area far larger than original expectations, capitalizing on the growing awareness of environmental issues in the 1970s. Fritz's interest in the Big Thicket led to a fight against the Forest Service's practice of clearcutting and its effect on Red Cockaded Woodpeckers. Through litigation and …

Design of a Wearable Flexible Resonant Body Temperature Sensor with Inkjet-Printing
A wearable body temperature sensor would allow for early detection of fever or infection, as well as frequent and accurate hassle-free recording. This thesis explores the design of a body-temperature-sensing device inkjet-printed on a flexible substrate. All structures were first modeled by first-principles, theoretical calculations, and then simulated in HFSS. A variety of planar square inductor geometries were studied before selecting an optimal design. The designs were fabricated using multiple techniques and compared to the simulation results. It was determined that inductance must be carefully measured and documented to ensure good functionality. The same is true for parallel-plate and interdigitated capacitors. While inductance remains relatively constant with temperature, the capacitance of the device with a temperature-sensitive dielectric layer will result in a shift in the resonant frequency as environmental or ambient temperature changes. This resonant frequency can be wirelessly detected, with no battery required for the sensing device, from which the temperature can be deduced. From this work, the optimized version of the design comprises of conductive silver in with a temperature-sensitive graphene oxide layer, intended for inkjet-printing on flexible polyimide substrates. Graphene oxide demonstrates a high dielectric permittivity with good sensing capabilities and high accuracy. This work pushes the …

Determinacy of Schmidt's Game and Other Intersection Games
Schmidt's game, and other similar intersection games have played an important role in recent years in applications to number theory, dynamics, and Diophantine approximation theory. These games are real games, that is, games in which the players make moves from a complete separable metric space. The determinacy of these games trivially follows from the axiom of determinacy for real games,ADR, which is a much stronger axiom than that asserting all integer games are determined, AD. One of our main results is a general theorem which under the hypothesis AD implies the determinacy of intersection games which have a property allowing strategies to be simplified. In particular, we show that Schmidt's (α,β,ρ) game on R is determined from AD alone, but on Rn for n≥3 we show that AD does not imply the determinacy of this game. We then give an application of simple strategies and prove that the winning player in Schmidt's (α,β,ρ) game on R has a winning positional strategy, without appealing to the axiom of choice. We also prove several other results specifically related to the determinacy of Schmidt's game. These results highlight the obstacles in obtaining the determinacy of Schmidt's game from AD

The Determinants and Consequences of Having a Chief Operating Officer
This study examines the determinant and consequences of having a chief operating officer (COO). Specifically, we investigate chief executive officer (CEO) related factors that affect the choice to employ a COO and look into the impact of having a COO on firm operational efficiency using a data envelopment analysis (DEA)-based measure. Although prior literature has extensively investigated the role of CEOs and chief finance officers (CFOs) on firm outcomes, few studies focus on the impact of COOs. Thus, this study explores characteristics associated with the likelihood that a firm will have a COO. This research also sheds light on the effect of COOs on firm operational efficiency because the core duties of COOs include optimizing operational performance and improving cost efficiency. Our results imply that CEO busyness, CEO ability, CEO demographic characteristics, and CEO network size have a significant impact on the decision to employ a COO. We also find that firms that have a COO have a lower level of operational efficiency than firms that do not. This result implies that the cost of having a COO outweighs the benefit of having one. The effects last for three years on average. Further, we find that firms with a COO …

Determining Event Outcomes from Social Media
An event is something that happens at a time and location. Events include major life events such as graduating college or getting married, and also simple day-to-day activities such as commuting to work or eating lunch. Most work on event extraction detects events and the entities involved in events. For example, cooking events will usually involve a cook, some utensils and appliances, and a final product. In this work, we target the task of determining whether events result in their expected outcomes. Specifically, we target cooking and baking events, and characterize event outcomes into two categories. First, we distinguish whether something edible resulted from the event. Second, if something edible resulted, we distinguish between perfect, partial and alternative outcomes. The main contributions of this thesis are a corpus of 4,000 tweets annotated with event outcome information and experimental results showing that the task can be automated. The corpus includes tweets that have only text as well as tweets that have text and an image.

The Differences in Mental Effort and Task Difficulty between Veterans and Non-Veterans in Bachelor of Applied Arts and Science Degree Programs at Texas Public Universities
This dissertation seeks to determine the differences between veteran and non-veteran students' mental effort and task difficulty within undergraduate online courses in Bachelor of Applied Arts and Sciences (BAAS) programs at three public Texas universities. The BAAS program is geared toward non-traditional students, which includes veterans. The courses are delivered in flexible formats, including online courses, face-to-face courses, and blended courses, which use a combination of online and face-to-face courses. After reviewing literature and utilizing both the cognitive theory of multimedia learning and the cognitive learning theory, a survey was conducted using undergraduate students enrolled in BAAS programs at three public Texas universities. The data was analyzed by conducting a factorial ANOVA and Pearson correlation to determine if there was a difference between veterans and non-veteran students' mental effort and task difficulty within online courses within the BAAS programs. The results indicated that that all three hypotheses failed to reject the null hypotheses that: (1) there is no difference in mental effort of students who had military service, versus those who did not have military service, (2) there is no difference in mental effort of students who had military service, versus those who did not have military service, and (3) …

Discourse Indicative of Computational Thinking within a Virtual Community
This study explores the phenomenon of computational thinking indicated by the use of Bloom's taxonomy's cognitive domain verbs in the Scratch community, the online, collaborative environment for the Scratch Visual Programming Language (VPL). A corpus of 660,984 words from three Scratch community sub-forums provide the data for this study. By semantically aligning cognitive domain verbs of Bloom's revised taxonomy to computational thinking (CT) dimensions, the occurrences of the verbs in Scratch community sub-forums are used to indicate instances of computational thinking. The methodology utilizes qualitative coding and analysis with R® and RStudio®. The findings show language attributes such as expressions of imagination, sharing of creative details, collaborative development ideas, teaching, modeling, innovating, solutions focused, and technical support to be indicative of computational thinking and CT dimensions. The computational thinking dimension referred to as computational perspectives occurs most frequently within Scratch community participant discourse. The environmental factors found to contribute to computational thinking and the CT dimensions are supporting tools, personalized learning, supportive organizational culture, social learning, and organizational support. Common among the three computational dimensions is the contributing environmental factor described as supportive organizational culture, with the computational perspectives dimension prevailing among the corpora. The characteristics of computational perspectives and …

Donor-Acceptor Systems: Photochemistry and Energy Harvesting Applications
Donor-acceptor systems have unique properties that make them ideal candidates for solar energy harvesting through mimicry of natural photosynthesis. This dissertation is focused on unraveling those unique properties in various types of donor-acceptor systems. The systems investigated are categorized as closely linked, push-pull, supramolecular, and multi-unit. As part of the study, photosynthetic analogues based on BF2-chelated dipyrromethene (BODIPY), porphyrin, phthalocyanine, truxene, ferrocene, quinone, phenothiazine (PTZ), perylenediimide (PDI), fullerene (C60), dicyanoquinodimethane (DCNQ), tetracyanobutadiene (TCBD), and triphenylamine (TPA) are investigated. The effects of proximity between donor-acceptor entities, their geometrical orientation relative to each other, push-pull character of substituents, and competitive energy and electron transfer are examined. In all systems, primary events of photosynthesis are observed, that is absorption and energy transfer and/or electron transfer is witnessed. Ultrafast transient absorption spectroscopy is utilized to characterize the photo-induced events, while other methods such as steady-state luminescence, cyclic voltammetry, differential pulse voltammetry, chronoamperometry, and computational calculations are used to aid in the characterization of the donor-acceptor systems, in particular their applicability as solar energy harvesters.

The Ecological Importance and Population Structure of Magellanic Woodpeckers (Campephilus magellanicus) in the World's Southernmost Forests
The Magellanic woodpecker (Campephilus magellanicus), the largest woodpecker in Central and South America, is declining throughout its range. Notably, limited research has been conducted on the Campephilus genus, especially for island populations. Mostly during austral summers 2015-2017, I explored the ecological importance and population structure of Magellanic woodpeckers on Navarino Island, Chile (55°04′S, 67°40′W). First, I assessed how coleopteran larval density and distribution within trees may influence Magellanic woodpecker foraging behavior. Second, I designed an experiment to determine which of three detection methods would best elicit a woodpecker detection. Third, I conducted a population genetics study to elucidate trends within and among Magellanic woodpecker populations to better inform management decisions. I identified two coleopteran species: one lucanid (Erichius femoralis) and one cerambycid (Microplophorus magellanicus) within two lenga (Nothofagus pumilio) trees foraged on by Magellanic woodpeckers. Maximum woodpecker excavation depths were 71-90 mm; most larval gallery depths were 51-70 mm. The drumming device most effectively influenced the likelihood of a woodpecker detection. The odds of a woodpecker responding were 2.14 times more likely than responding to either a playback or control. On Navarino Island, I observed a pattern of isolation by distance among sampled woodpeckers, slight female sex-biased dispersal, and family …

The Effect of Accelerated Instruction on Summer Regression
The purpose of this study was to evaluate the benefit accrued to fifth-grade students who participated in a summer school accelerated instruction program utilizing accelerated instructional practices in a Texas school district. The secondary intent was to determine the program's effect on student regression or retention as measured by Measures of Academic Progress (MAP) scores and State of Texas Assessment of Academic Readiness (STAAR) tests in reading and mathematics. The district provided summer accelerated instruction to fifth-grade students who did not pass reading and/or mathematics portions of STAAR for the May administration. For this study, I focused on the 2018 summer accelerated instruction offered by the district, using a mixed methods design to analyze the effectiveness of accelerated instruction for the students who participated in the summer program. A paired samples t-test was conducted to evaluate if students who failed the May STAAR in either reading or mathematics increased their scores on the June STAAR. Also, a paired samples t-test was conducted to determine if these same students increased their fall MAP test when compared to the spring MAP test. Teachers were interviewed to determine their perceptions of the most beneficial parts of summer school for students who attended. The …

The Effect of Welfare Benefit Levels on Female Headship in the AFDC and TANF Eras
The purpose of this study is to revisit the question of whether welfare benefit levels influence female headship, and whether the effect differs between the two main eras of welfare policy relevant to female headship, Aid to Families with Dependent Children (AFDC) and Temporary Assistance to Needy Families (TANF). This study adds to the existing literature by including more up to date data allowing for a comparison between the AFDC and TANF eras. Results show that the effect of welfare benefits on female headship rates changes from negative to positive after welfare reform occurred among blacks, while no change occured among whites.

Effective Leadership Practices in Improvement-Required Schools
This mixed-methods study identified the effective practices of the principal and leadership team in an Improvement-Required (IR) high school that significantly influenced student achievement and guided their school from IR to a rating of Met Standard in one year. IR or F schools under the new system are schools that failed to meet the state accountability target goals. The high school in this study had a large culturally and economically diverse student population with a high percentage of English learners. The leadership practices were identified through four themes revealed by the qualitative data analysis of focus group and individual in-depth interviews: (a) importance of instructional, collaborative leadership, (b) intentional planning of effective instruction for all students, (c) consistent use of data to guide instruction, and (d) ongoing, data based, targeted staff development. The study findings are significant due to strong corroboration between the qualitative data collected from the interviews and the quantitative results from the faculty survey.

Effectiveness of Child-Centered Play Therapy on Childhood Depression
Depression in childhood is a significant mental health concern, impacting cognitive, affective, social, behavioral, and physical domains. Children who experience depressive symptoms are at an increased risk for physical and mental health, social, and behavioral problems throughout adulthood. Children who are marginalized due to their socioeconomic status, racial and ethnic identities are at an increased risk to experience depression and limited access to mental health care. Further, previous research has demonstrated limited efficacy of depression treatments for young children. In this study, I examined the efficacy of child-centered play therapy [CCPT], a culturally and developmentally responsive treatment, on depression among young children. Participants were 71 children from five Title 1 elementary schools in the southwestern U.S. referred by school personnel for depressive symptoms (49 males, 22 females; ages 5-9, mean age M = 6.21). The sample consisted of 14 (19.7%) African American, 3 (4.2%) Asian American, 15 (21.1%) biracial, 19 (26.8%) Caucasian, and 20 (28.2%) Latino children. Participants were randomly assigned to eight weeks of twice-weekly CCPT treatment group (n = 34) or a waitlist control group (n = 37). Results of doubly multivariate repeated-measures MANOVA revealed statistically significant improvement in depressive symptoms for children who participated in CCPT on …

The Effects of Instructions on Schedule Sensitivity
There are many situations in which human performances appear insensitive to changing contingencies of reinforcement when compared to nonhuman operant performances. Explanations of these discrepancies have appealed to rule-governance and have provided some evidence that instructions produce these differences by restricting response alternatives as well as functioning as discriminative stimuli for other contingencies. In order to further evaluate these potential functions, a canonical study on rule-governance was systematically replicated. Five undergraduate participants were tasked with earning blocks by pressing a button during LED-signaled, fixed-ratio 7 and differential-reinforcement-of-low-rate 5-s schedules of reinforcement. Phase 1 of the experiment switched between these two schedules, with the schedule alternating every 1 minute. Phase 2 added instructions to "Go Fast" and "Go Slow" to the LEDs and programmed the lit LED to switch 30 seconds into each 1-minute session. Phase 3 removed the instructions from the LEDs and returned to the procedures of phase 1, with only one LED lit during each 1-minute session. Results showed that instructions influence the response rates as well as stimulus control over those rates. Results also showed that all participants ignored instructions conflicting with the reinforceable rate by the end of Phase 2. These findings indicate that instances of …

The Effects of Leadership Development on Student Retention in STEM
The Science Teaching and Research (STAR) Leadership Program at Austin College was designed to intentionally include leadership development into the science curriculum and provides an opportunity to determine the effects of student leadership development on the retention of students in science, technology, engineering, and mathematics (STEM). This dissertation used a quasi-experimental design to determine: 1) if STEM retention can be explained though the inclusion of leadership development into the curriculum; 2) if there is a difference between Austin College students who choose a STEM major compared to students who do not; and 3) if there is a difference between Austin College students who complete a STEM degree compared to students who do not. Census data were collected on 2,137 students who enrolled in STEM courses beginning in the fall of 2008 through the spring of 2017, and factors affecting retention were compared across three 3-year time periods that spanned before the program was initiated through wider implementation. A logistic regression showed that there was no significant positive association between leadership development and STEM retention when taking into account other pre-college and demographic factors that have been linked to retention in the literature. However, a one-way ANOVA showed that the academic …

The Effects of Probiotics on Growth, and Metabolism in Juvenile Oreochromis mossambicus (Mozambique Tilapia)
Improving growth, lowering mortality rates, and having a faster turnaround to harvest is essential for the future of commercial aquaculture. The primary goal of this study was to determine if introducing a single strain probiotic Lactobacillus rhamnosus IMC 501 into the feed regimen of a commercially important aquaculture freshwater fish, Mozambique tilapia (Oreochromis mossambicus), would decrease mortality; change metabolic rates; and increase tissue wet mass (MW), standard length, growth rate and feed conversion rate (FCRs). IMC501 was added to the fishmeal in four increasing concentrations and compared to a control without probiotics. Results from two-way ANOVAs showed that both treatment levels and elapsed time had a significant effect on both mean standard length and wet mass; in the latter case, time points and treatments interacted with one another, showing that tilapia grew best with a moderate level of probiotics present. The growth benefits of probiotics continued for months after the initial treatments. Oxygen consumption (metabolic rate) was measured using closed respirometry and resulted in recording the first values for juvenile tilapia treated with probiotics. For oxygen consumption, there were significant treatment and time effects with significant interactions, indicating that metabolism increased with probiotics once the dosage exceeded three times the …

Efficient Solar Energy Harvesting and Management for Wireless Sensor Networks under Varying Solar Irradiance Conditions
Although wireless sensor networks have been successfully used for environmental monitoring, one of the major challenges that this technology has been facing is supplying continuous and reliable electrical power during long-term field deployment. Batteries require repetitive visits to the deployment site to replace them once discharged; admittedly, they can be recharged from solar panels, but this only works in open areas where solar radiation is unrestricted. This dissertation introduces a novel approach to design and implement a reliable efficient solar energy harvester to continuously, and autonomously, provide power to wireless sensor nodes for long-term applications. The system uses supercapacitors charged by a solar panel and is designed to reduce power consumption to very low levels. Field tests were conducted for more than a year of continuous operation and under a variety of conditions, including areas under dense foliage. The resulting long-term field data demonstrates the feasibility and sustainability of the harvester system for challenging applications. In addition, we analyzed solar radiation data and supercapacitor charging behavior and showed that the harvester system can operate battery free, running on the power provided by supercapacitors. A battery is included only for backup in case the supercapacitor storage fails. The proposed approach provides …

Eleven: A Novel
Trauma novel refers to a work of fiction that discloses serious loss or intense fear on individuals and groups. The traumatic experience is repetitious, timeless, and unspeakable. Gayl Jones, Jesmyn Ward, Tayari Jones, Alice Walker, and Toni Morrison are only a few authors who have written this type of novel. The traumatic events that occur in the books are rape, miscarriage of justice, and slavery, to name a few. The experienced trauma manifest as fragmented memory, silence, commitment phobia, intimate distance, and feelings of abandonment. In her book, Quiet As It's Kept: Shame, Trauma, and Race in the Novels of Toni Morrison, J. Brooks Bouson argues that the traumatic experience of slavery and "white racist practices" throughout history produced a "collective African-American experience" which appears in fiction and in the fabric of American culture (4) as intergenerational trauma. African American authors are reimaging history told primarily in first and third person limited, and even if the novel has an omniscient point of view, it can change to third person limited. They use point of view to adeptly navigate the effects of trauma on the psyche interweaving closeness and distance to manipulate the emotional, intellectual, and moral responses the author desires. …

Encouraging Tolerance of and Cooperation with Dental/Medical Routines
The participant is a 61-year-old woman, diagnosed with a generalized anxiety disorder and profound intellectual disability who was referred to a behavior-disorders clinic, to increase cooperation with routine dental procedures. I used a behavioral treatment package consisting of stimulus fading, differential reinforcement, and extinction to establish tolerance of, and cooperation with, routine dental procedures. Results showed that cooperative responding varied throughout the progression of teaching the prerequisite steps (sitting in a chair, sitting in a variety of chairs, then working on sitting in the dental chair). However, by the end of the study, the participant engaged in the behavior of open mouth for 30 s and tolerated/cooperated with the experimenter using a plastic visual inspection tool for 30 s. Further research should evaluate the effectiveness of a similar treatment package to develop a more streamlined and systematic framework to improve compliance and tolerance.

Encrypted Collaborative Editing Software
Cloud-based collaborative editors enable real-time document processing via remote connections. Their common application is to allow Internet users to collaboratively work on their documents stored in the cloud, even if these users are physically a world apart. However, this convenience comes at a cost in terms of user privacy. Hence, the growth of popularity of cloud computing application stipulates the growth in importance of cloud security. A major concern with the cloud is who has access to user data. In order to address this issue, various third-party services offer encryption mechanisms for protection of the user data in the case of insider attacks or data leakage. However, these services often only encrypt data-at-rest, leaving the data which is being processed potentially vulnerable. The purpose of this study is to propose a prototype software system that encrypts collaboratively edited data in real-time, preserving the user experience similar to that of, e.g., Google Docs.
