While computational chemistry methods have a wide range of applications within the set of traditional physical sciences, very little is being done in terms of expanding their usage into other areas of science where these methods can help clarify research questions. One such promising field is Forensic Science, where detailed, rapidly acquired sets of chemical data can help in decision-making at a crime scene. As part of an effort to create a database that fits these characteristics, the present work makes use of computational chemistry methods to increase the information readily available for the rapid identification and scheduling of drugs to the forensic scientist. Ab initio geometry optimizations, vibrational spectra calculations and ESI-MS fragmentation prediction of a group of common psychedelics are here presented. In addition, we describe an under development graphical user interface to perform ab initio calculations using the GAMESS software package in a more accessible manner. Results show that the set of theoretical techniques here utilized, closely approximate experimental data. Another aspect covered in this work is the implementation of a boiling point estimation method based on group contributions to generate chemical dispersion areas with the ALOHA software package. Once again, theoretical results showed to be in …

The thesis implements a vision-based leader-follower tracking algorithm on a ground robot system. One camera is the only sensor installed the leader-follower system and is mounted on the follower. One sphere is the only feature installed on the leader. The camera identifies the sphere in the openCV Library and calculates the relative position between the follower and leader using the area and position of the sphere in the camera frame. A P controller for the follower and a P controller for the camera heading are built. The vision-based leader-follower tracking algorithm is verified according to the simulation and implementation.

Social media has the potential to be a critical force in creating connected educators. The collaborative nature of social media encourages personal connection, professional enrichment, and learning through co-creation of meaning. Secondary teachers are in a place that would permit them to harness these affordances, not only in their personal and professional environments, but also in their classrooms. This qualitative phenomenographic study aimed to uncover how secondary teachers used social media for personal, professional, and instructional purposes. Further, this study sought to understand secondary teachers' attitudes and beliefs toward social media. Their current state of social media use was also of interest, as were the types of relations secondary teachers had with social media. To better understand the stories and experiences realized by these educators, ten secondary teachers were engaged using a semi-structured interview process. These teachers presented with varying backgrounds, education, and teaching focus. The interviews provided a textual representation of their social media stories. Interview transcripts were transposed into thick rich accounts describing their experiences, thoughts, ideas, and how they understood social media in their personal, professional, and instructional lives. It was found that the current state of social media use by secondary teachers was primarily limited to …

This thesis is a study of early modern English travel narratives and the ways they presented the German states and their people to the public through the medium of print. It is based on an analysis of forty seven published travel narratives written by men and women who toured Germany and wrote about their experiences. The study situates these writings in the context of the growing sense of national identity in early modern Europe and offers an assessment of how these travel narratives contributed to a uniquely English understanding of Germany. As English travel narratives about Germany in the early modern period evolved, writers highlighted distinctive characteristics they believed Germans possessed, and compared their subjects to themselves. Travelers presented diverse and even conflicting views on a variety of subjects related to Germany. Nevertheless, by the late eighteenth century, English travelers had fashioned a common set of images, stereotypes, and characteristics of Germany and its people.

Education reform initiatives continue to push schools to improve methods of measuring accountability intended to improve student achievement in the United States. Federal programs like the Teacher Incentive Find (TIF) provide school districts with funds to develop and implement school accountability and leadership programs. Teacher leadership is one of the concepts being formally developed amongst these initiatives. My applied thesis project focused on work I conducted with a team of researchers at American Institutes for Research, where we evaluated a teacher leadership program in its third year of implementation. Teacher leadership is facilitated through distributive leadership. School leaders distribute responsibilities that provide teachers with opportunities to extend their expertise outside of their own classrooms. My thesis explores teacher leadership roles and investigates implementation across the client school district. It also discusses how particular anthropological theories about communities of practice, learning, and identity can provide a foundation for conceptualizing teacher leadership implementation and the social interactions between program actors.

Since the recession of 2008, there has been an increased scrutiny of higher education, with little research done on how this affects high school students' college search process. This study seeks to understand how college perceptions are formed and how they affect the college decision process of high school students in Sioux Falls, South Dakota. In order to gain a holistic perspective of this process, this study utilized a mixed method approach of analyzing public data, conducting interviews with community members and students, conducting a focus group with high school guidance counselors, and administering a survey to high school students. This study found that students in this area form their perceptions of college in three distinct phases and that these phases affect a student's college priorities. Special attention was given to how academics, cost and location contributed to a student's overall college decision. These findings can be used to assist faculty and staff at higher education institutions in creating effective messaging and programming that relate to this group of students.

West Nile virus (WNV) is a geographically endemic mosquito-borne flavivirus that has spread across the United States infecting birds, mosquitos, humans, horses and other mammals. The wide spread nature of this virus is due to the ability of the mosquito vector to persist in broad, ecological diverse environments across the United States. In this study, mosquito populations in North Texas region were sampled for detection of Wolbachia, blood meal source, and WNV. The ultimate goal of this study was to examine the potential of a biocontrol agent, Wolbachia sp. that colonizes the hindgut of various insects, including mosquitos, as a natural means to interrupt virus transmission from mosquitos to other hosts, including humans. In Australia, Wolbachia sp. from fruit flies (Drosophila melanogaster) have been successfully used to block transmission of a similar pathogenic virus from mosquitos responsible for transmission of Dengue fever. Here, mosquitoes were collected using CDC style Gravid Traps in Denton, Texas, from October 2012 through September 2014. Collected mosquitoes were identified, sexed, and categorized as to the amount of host blood in their alimentary system using a Zeiss Axio Zoom microscope (Carl Zeiss Microscopy, LLC, Thornwood, NY). Culex quinquefaciatus was the dominant blood engorged species collected. Smaller …

Custodial grandmothers and grandchild (aged 4 to 12) dyads (N = 170) completed self-report, other-report, and an observational task that captured child HI, expressive social support, and custodial grandmother-grandchild compliance variables. A multivariate analysis of covariance tested differences between high and low hyperactivity-inattention on observed parenting variables while controlling for child age. While overall results were not significant, there were significant differences between child age and observed parenting variables. A hierarchical regression model revealed that, when controlling for age, child hyperactivity-inattention does not moderate the relationship between commands given by a custodial grandmother and child compliance, but revealed that direct commands from the grandmother predicted compliance. A second hierarchical regression model suggested that encouragement and praise (versus criticism and discouragement) from a grandmother moderated the relationship between grandmother commands and child compliance, when controlling for child age. It appeared that when grandmothers gave indirect commands more frequently, encouragement and praise instead of criticism was associated with greater compliance. In dyads with frequent direct commands given, compliance was high, however dyads who scored high in direct commands with criticism and discouragement were most likely to comply. This study adds to the literature by providing insight into the challenges and strengths for …

This dissertation provides a philosophical analysis about the influence colonialism had over capitalism's current configuration and how their intricate interplay impacts both the social and the ecological spheres, in both central and peripheral countries. Such analysis draws from the work of José Lutzenberger, a Brazilian environmentalist. The current capitalist economic system tends to disregard the environment, since it would be greatly affected by negative externalities. A negative externality is an economic activity that imposes a negative effect on an unrelated third party. Many negative externalities are related to the environmental consequences of production and consumption. In addition, this dissertation explores the fact that an ecological crisis is also a social crisis. A genealogical and existential thread going from Brazil's early days as one of Portugal's colonies to the present is drawn, showing how colonialism helped to create the foundations and the conditions for the current exploitative capitalist system, in Brazil and elsewhere. To change this situation, the environment should not be entrusted to private interests but to an institution responsible for the good of society as a whole. Genuinely green economies are more prone to appear on the periphery, but only if global economic justice is achieved first.

The purpose of this study is to evaluate the potential benefit of two hours of activities involving 2D and 3D fabricators on the spatial reasoning skills of children in Grades 4 and 5, ages 9 to 10, from a private school in Southeast Texas. Can the introduction to hands-on activities with products created with these devices and learning about how these devices operate improve spatial reasoning skills? The research also evaluates the use of the Shapes Test as a valid measure of the spatial reasoning skills of children. The Cube Design and Spatial Memory subtests of the UNIT (Universal Nonverbal Intelligence Tests) were used for evaluating the spatial reasoning skills of the participants, based on their respected validity, along with a Shapes Test that is in development. Discussion regarding gender, language, and experiential theories of spatial reasoning skill development are included in the literature review.

A conditional discrimination training procedure was used to establish stimulus-stimulus relations that might lead to the emergence of relations that define playing by ear. The participants were four college students. Overall, the results varied across participants. Of the 3 participants who received Training 1 (hear-note-name/select-key), all 3 participants acquired that relation. Out of those 3 participants, 2 participants showed emergence of the hear-see-key-pressed/say-note-name relation after Training 1. Of the 3 participants who received Training 2, (hear-note-name/select-tone), 2 participants acquired that relation for at least one set. Out of those 3 participants, 1 participant showed emergence of the hear-tone/say-note-name relation. One out of three participants was successful in correctly playing a sequence of four notes by ear at the end of the study. One participant did not complete the study due to availability conflicts. The overall results can suggest that the relations used in this study should be taken into account when training someone to play by ear. However, the current data do not allow us to conclude whether it is necessary to teach or test all of these relations in order to teach playing by ear.

This dissertation seeks to explain the puzzle in the state politics literature which expects females to benefit from the enactment of term limits, but initial research finds the number of female in office decreases after the implementation of term limits. Examining this puzzle involves three separate stand-alone chapters which explore female candidate emergence (1), success rates (2), and women-friendly state legislative districts (3). The goal of the dissertation is to reconcile the puzzle while adding insight into how female candidates behave at the state-level. Overall, I find that term limits increases female descriptive representation by increasing the likelihood a female candidate will run and win an election.

Denton, Texas consistently reaches ozone nonattainment levels. This has led to a large focus of air pollution monitoring efforts in the region, with long-range transport being explored as a key contributor. For this study, the University of North Texas Discovery Park campus was chosen as a prospective location for an extensive air quality monitoring station. Sixteen years of ozone and meteorological data for five state-run monitoring sites within a 25 mile radius, including the nearest Denton Airport site, was gathered from TCEQ online database for the month of April for the years 2000 to 2015. The data was analyzed to show a historical, regional perspective of ozone near the proposed site. The maximum ozone concentration measured at the Denton Airport location over the 16 year period was measured at 96 ppb in 2001. Experimental ozone and meteorological measurements were collected at the Discovery Park location from March 26 to April 3 and April 8 to April, 2016 and compared to the Denton Airport monitoring site. A time lag in ozone trends and an increase in peak ozone concentrations at the proposed location were observed at the proposed site in comparison to the Denton Airport site. Historical and experimental meteorological data …

The effectiveness of memory specificity training (MeST) was compared with standard cognitive processing therapy (CPT) in treatment of individuals with posttraumatic stress disorder. Eighteen adults aged 18-36 were randomly assigned to the MeST intervention (n = 9) or to the active control group (n = 9) of CPT. Both treatments were administered in group format across 6 weeks. MeST consisted of 6 weekly sessions, while CPT consisted of 12 biweekly sessions. The trial was undertaken in the Psychology Clinic of the University of North Texas, with randomization to conditions accomplished via computer random number generator. The primary outcome measure was change in PTSD symptoms post-treatment from baseline. Sixteen individuals (13 women and 3 men; MeST n = 8 and CPT n = 8) completed treatment and their data was analyzed. MeST significantly decreased PTSD symptomology at post-treatment and these results were maintained at 3 months post-treatment. MeST was found to be as effective as the established CPT intervention at reducing PTSD symptomology. Both MeST and CPT significantly increased participants' ability to specify memories upon retrieval at post-treatment, with results maintained at follow-up. There were no significant effects of MeST or CPT in ability to increase overall controlled cognitive processing at …

Research shows that preadolescent females are more prone to negative self-perceptions than their male counterparts which places them at greater risk of developing mental health problems stemming from low self-image. The purpose of this randomized, controlled outcome study was to examine the effectiveness of group activity play therapy (GAPT) compared to an evidenced based social skills/self-esteem group. Participants were 29 fourth and fifth grade girls in two Title I schools in the southwest U.S. referred by teachers and school counselors as presenting with low self-esteem. Participants identified as 45% Latina, 38% Caucasian, 14% African American, and 3% Asian. Children were randomly assigned to either 16 sessions of GAPT (experimental group; n = 15) or 13 sessions of an evidenced based social skills/self-esteem group intervention (control group; n = 14). Results from a 2 (Group) by 3 (Times) repeated measures ANOVA indicated that, compared to the control group over time, the GAPT group reported statistically significant improvement in self-esteem with a moderate to large treatment effect. Teachers did not report a statistically significant difference between the two groups over time. However, teachers reported noteworthy improvement for children in both treatment groups, with generally stronger improvement for the GAPT group. Overall, results …

This thesis dissertation mainly compares and investigates laboratory study of different implementation methodologies of applied control systems and how they can be adopted in industrial, as well as commercial, automation applications. Namely the research paper aims to assess or evaluate eventual feedback control loops' performance and robustness over multiple conventional or state-of-the-art technologies in the field of applied industrial automation and instrumentation by implementing a laboratory case study setup: the ball on beam system. Hence, the paper tries to close the gap between industry and academia by: first, conducting a historical study and background information of main evolutional and technological eras in the field of industrial process control automation and instrumentation. Then, some related basic theoretical as well as practical concepts are reviewed in Chapter 2 of the report before displaying the detailed design. After that, the next Chapter, analyses the ball on beam control system problem as the case studied in the context of this research through reviewing previous literature, modeling and simulation. The following Chapter details the proposed design and implementation of the ball on beam case study as if it is under the introduced distributed industrial automation architecture. Finally, Chapter 5 concludes this work by listing several …

Despite the ruling of Brown vs. The Board of Education of Topeka, segregation in schools is still quite visible with suburban schools educating a student body of more than 70% White and urban schools comprised of mostly Black, Hispanic, and Asian students. Ideally, a school should dispel social and structural inequities through curriculum and quality resources, but fallibly, schools continue to be the vehicles to maintaining the status quo. Students who develop critical awareness and cultivate a critical literacy stance can become agents of change toward a more democratic society. In the current study, urban upper-elementary-age students were asked to engage in a critical literacy event by critically examining the power positions of characters in books that depict historical social injustice. The six female participants met in several sessions to read books and a newspaper article, use a critical reader response tool, and then engage in critical conversations about the books' characters. Their dialogue was recorded and analyzed using a critical discourse qualitative methodology. The findings show that older elementary students are capable of seeing multiple perspectives of an issue and can explain characters' power from born from privilege and fueled by fear and how a shift in power may …

Although there has been research conducted in the area of information seeking behavior in children, the research focusing on young children, more specifically on pre-kindergarten students, is almost nonexistent. Children at this age are in the preoperational developmental stage. They tend to display curiosity about the world around them, and use other people as a means to gain the information they are seeking. Due to the insistence from President Obama to implement pre-kindergarten programs for all low and middle class children, the need to understand the cognitive, emotional, and physical needs of these children is becoming increasingly imperative. To researchers, the actions displayed by these young children on a daily basis remain vital in determining the methods by which they are categorized, studies, and even taught. This study employed Deci and Ryan's self-determination theory (SDT), Dervin's sense-making theory, Kuhlthau''s information search process model (ISP), and Shenton and Dixon's microcosmic model of information seeking via people to lay the theoretical foundational framework. This ethnographic study aimed to fill the age gap found in information seeking literature. By observing young children in the school setting, I gained insight into how these children seek information. The resulting information collected via field observations and …

The purpose of the study was to investigate how the online, computer-based learner's personal learning profile (Preference), the content delivery method supplemented with visual content based on Neil Fleming's VARK (visual, aural, read/write, kinesthetic) model (Content), and the interaction of Preference and Content, influenced learner performance (Performance) and/or learner self-reported satisfaction (Satisfaction). Participants were drawn from a population of undergraduates enrolled in a large public southwestern research university during the fall 2015 semester. The 165 student participants (13.79% completion rate) were comprised of 52 (31.5%) females and 113 (68.5%) males age 18-58+ years with 126 (76.4%) age 18-24 years. For race/ethnicity, participants self-identified as 1 (0.66%) American Indian/Alaska Native, 21 (12.7%) Asian/Pacific Islander, 27 (16.4%) Black, non-Hispanic, 28 (17%) Hispanic, 78 (47.3%) White, non-Hispanic, 10 (6.1%) other. Reported socioeconomic status was 22 (13.3%) withheld, 53 (32.1%) did not know, 45 (27.3%) low, 13 (7.9%) moderately low, 16 (9.7%) middle, 8 (4.8%) upper middle, and 8 (4.8%) upper. This causal-comparative and quasi-experimental, mixed-method, longitudinal study used researcher-developed web-based modules to measure Performance and Satisfaction, and used the criterion p < .05 for statistical significance. A two-way, 4 x 3 repeated measures (Time) analysis of variance (RM-ANOVA) using Preference and Content was …

Superstitions flourish in cultures around the word and in everyday life. Superstitions are so prevalent and influence personal and political decisions, therefore, we sought to develop a classroom demonstration of superstitious behavior that could be used to show quickly and effectively how powerful adventitious reinforcement could be in modifying behavior. An online game was developed and played by one hundred thirteen university students enrolled in a class on critical thinking. Participants gained points (reinforcement) arbitrarily during either 25% or 50% of each game's (A or B) 3 minute duration. Although points were non-contingent, students often engaged in superstations rules or patterns. Results of both self-reports and computer generated data showed, the games were successful in producing superstitious behavior patterns in about 50% of our participants. More students showed superstitious behavior in the 50% game than in the 25% game. We conclude that this is due to the higher reinforcement rate of in 50% game. For future studies, rearranging the stimulus array into a pattern that does not itself strongly control behavior could help refine the results.

Despite an increasing demand for college graduates skilled in science, technology, engineering, and mathematics ("STEM") fields, a substantial number of students who choose these majors leave after taking their first-year "gateway" math and science coursework. Research has shown GPA to be a salient predictor of persistence in STEM majors: Students who earn high grades in gateway courses are more likely to continue, and those who earn low grades are more likely to leave. However, a small number of students defy that expectation: Despite a low gateway course GPA, they persist not just to the sophomore year but all the way to graduation. The purpose of this study was to determine what other experiences, motivations, or attributes aside from academic performance influence these students to persist. A qualitative approach was taken with the use of semi-structured interviews, which provided a means for analysis based on insights directly from students. An invitation was sent to a cohort of graduating math and science majors at a large public institution, and 10 eligible volunteers were chosen to participate. A thematic analysis was conducted to seek common themes in the students' interviews regarding their experiences in their gateway coursework, their feelings towards their chosen major, …
