Theoretical Analysis of Drug Analogues and VOC Pollutants (open access)

Theoretical Analysis of Drug Analogues and VOC Pollutants

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 Design and Implementation of an Effective Vision-Based Leader-Follower Tracking Algorithm Using PI Camera (open access)

The Design and Implementation of an Effective Vision-Based Leader-Follower Tracking Algorithm Using PI Camera

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.

The Implications of Social Media: Secondary Teachers' use of Social Media for Personal, Professional, and Instructional Purposes (open access)

The Implications of Social Media: Secondary Teachers' use of Social Media for Personal, Professional, and Instructional Purposes

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 …

Imagining the Empire: Germany Through the Eyes of Early Modern English Travellers (open access)

Imagining the Empire: Germany Through the Eyes of Early Modern English Travellers

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.

Teacher Leadership Implementation: Change Agents in a Large Urban School District (open access)

Teacher Leadership Implementation: Change Agents in a Large Urban School District

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.

An Exploration of College Attitudes among Sioux Falls High School Students (open access)

An Exploration of College Attitudes among Sioux Falls High School Students

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.

Presence of Wolbachia, A Potential Biocontrol Agent: Screening for Vertebrate Blood Meal Source and West Nile Virus in Mosquitoes in the North Texas Region (open access)

Presence of Wolbachia, A Potential Biocontrol Agent: Screening for Vertebrate Blood Meal Source and West Nile Virus in Mosquitoes in the North Texas Region

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 …

Observed Parenting Aspects of Child Compliance in Custodial Grandfamilies (open access)

Observed Parenting Aspects of Child Compliance in Custodial Grandfamilies

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 …

Environmental Ethics from the Periphery: José Lutzenberger and the Philosophical Analysis of an Unecological Economics (open access)

Environmental Ethics from the Periphery: José Lutzenberger and the Philosophical Analysis of an Unecological Economics

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.
