One schedule of reinforcement that is used to decrease the rate of a target behavior is differential reinforcement of low rates (DRL). During this schedule, reinforcement is delivered for a target response if it occurs after a certain amount of time has passed since the last instance of this target response. The current study used a table-top game called PORTL and college student participants to investigate how collateral patterns develop and are disrupted during DRL schedules. After the participant developed a collateral pattern of behaviors with the objects, the researcher removed one of the objects that was part of the pattern and waited for a new pattern of behaviors to develop. Once the participant developed a new collateral pattern, the researcher removed a second object. This continued until there was only one object present. Results showed that the rate of reinforcement decreased following the removal of each object, then slowly increased as a new pattern developed.

The Austrian army played a crucial role in Napoleon's decisive defeat during the War of the Sixth Coalition. Often considered a staid, hidebound institution, the army showed considerable adaptation in a time that witnessed a revolution in the art of war. In particular, changes made after defeat in the War of the Fifth Coalition demonstrate the modernity of the army. It embraced the key features of the new revolutionary way of war, including mass mobilization, a strategy of annihilation, and tactics based on deep echelonment, mobility, and the flexible use of varied formations. While the Austrians did not achieve the compromise peace they desired in 1814, this represented a political failing rather than a military one. Nevertheless, the Austrian army was critical in securing the century of general European peace that lasted until the dawn of the Great War.

This paper examines the concept of safety as it encompasses the personal and technological spheres as imagined by a group of active duty service members, veterans, a police officer, and civilians, as well as the agency exercised by those with military or police backgrounds when it comes to safety technology. A group of seventeen individuals took part in a battlefield simulation to test a wearable junctional tourniquet created by ARMR Systems, LLC, an innovative advancement in tourniquet technology. After the simulation, participants were interviewed, surveyed, and took part in a focus group to determine not only product suitability but also to explore the underlying reasons for their recommendations for product changes. Results showed that those with military or police background performed safety rituals prior to duty and exercised agency in the desire to obtain the best possible personal safety devices and technology to be used for themselves and their comrade-in-arms. All participants expressed concerns for their safety in regards to technology in general, specifically, the hacking and use of personal data and what is perceived as lack of governmental oversight. Almost all of the changes to improve product safety, comfort, and utility were adapted. The topics discovered during the course …

When governments are unable or unwilling to provide necessary relief to communities, local faith-based congregations (FBCs) step in and fill the gap. Though shown to provide for so many needs following disaster, FBCs have largely been left out of the institutional emergency management cycle. The aim of this study was to explore the role of FBCs in the disaster response and recovery process and investigate how recovery impacts FBCs. The primary objective of this study is to gain a better understanding of FBCs and how to better integrate them into the formal emergency management process.The main questions were as follows: First, what is the role of FBCs during the disaster recovery process? Second, how do FBCs change (temporarily and permanently) during disaster recovery, and what factors may promote or inhibit change? To answer these questions, qualitative semistructured interviews were held to develop a case study of Katy, Texas and its recovery from Hurricane Harvey of 2017. The applied and conceptual implications resulting from this study, which apply to FBCs, researchers, emergency managers, and policy makers, highlight the opportunity to better incorporate FBCs formally into emergency management practices.

Members of Greek Life organizations consume more alcohol and participate in risky drinking behaviors at higher rate than their non-Greek counterparts due to deep rooted social norms within this population. Undergraduate sorority women at college and universities are often overlooked in research regarding trends in alcohol use in Greek Life organizations. However, women between the ages of 18 and 24 are more vulnerable to the consequences of heavy alcohol use compared to men, including liver disease, sexual assault, poor academic outcomes and post-collegiate alcohol use disorders (AUDs). Although higher education institutions are tasked with educating their students about safe alcohol use and protecting students from harm, these interventions are often inadequate in decreasing alcohol related consequences. Among students, sorority women consistently consume higher amounts of alcohol and exhibit higher rates of risky drinking behavior. This thesis aims to examine the unique alcohol-related consequences and risk factors sorority women face. Implications are discussed to guide college administrators, counselors and other supports that are likely to encounter issues associated with alcohol use within this population.

Online fandom communities exist as a hub of subcultural construction for people across the globe. For queer people, fandom represents a space to safely converge over mutual interests. Previous research has focused on queer fans and popular music fans independently, often taking a pathological approach. This study qualitatively examines queer participants in the Katy Perry fandom through surveys and one-on-one interviews. The theoretical backbone of the study is built around uses and gratifications theory, seeking to understand motivations for fandom participation. The concepts of the heteronormative matrix and queer resistance are additionally incorporated to analyze how LGBTQ+ fans combat societal norms. This research found seven motivations for queer fans to participate in online fandom, providing insight into an understudied community.

This work examines the lynching of twelve female victims in Texas from 1885 to 1926.

The appeal of moral panic studies, a once very popular sociological subfield, dropped precipitously around the turn of the century due in large part to debates about disproportionality, the notion a panicked group's concern about a perceived threat exceeds that warranted by its objective harmfulness. Classic theorists claim disproportionality is a panic's essential criterion and that it can be demonstrated by comparing a group's concerned reaction to the available facts. Critics argue it is a value-laden, ideologically tainted construct and often claim it cannot be demonstrated because there are no authoritative facts. These debates were and still are fraught with confusion. Perplexingly, both sides assume a shared definition despite clearly assessing the proportionality of different aspects of the relevant reaction. A typology differentiating the potential types of disproportionality either does not exist in the moral panic literature or remains shrouded in obscurity. In this paper, I review the classic theories, their critiques, and a new postmodern moral panic theory. By juxtaposing the different foci of the orthodox and contemporary theories, I derive a much-needed disproportionality typology. I also develop a new framework through which to assess moral panics predicated on this typology. My hope is these developments will stimulate a …

Sangpuy Katatepan Mavaliyw is a Taiwanese Aboriginal pop artist of the Pinuyumayan ethnic group. His albums have been acclaimed by Aboriginal listeners and Han-Taiwanese mainstream music critics for capturing the traditional Aboriginal sound and evoking the presence of the ancestors. In this thesis, I explore why Sangpuy's songs are understood to evoke ancestral spirit imaginary using a semiotic approach. I compare his music to traditional Pinuyumayan music such as pa'ira'iraw and shamanic songs to demonstrate how he uses similar musical gestures to evoke the sense of ancestral spirits. Other sonic elements such as the inclusion of the soundscape of a Pinuyumayan village provides a direct link to the lived experiences of the Pinuyumayan. I also position Sangpuy's music in the broader context of nationalism in Taiwan and how Sangpuy uses his music to negotiate Aboriginal issues such as land rights and environmentalism. Through this analysis, I demonstrate how Taiwanese Aborigines are incorporating their Indigenous ideology into popular music to carve out a space for themselves in Taiwanese society and garner more support for Indigenous rights in Taiwan.

The current study explored how the variability or lack thereof in interlocking behavioral contingencies (IBC) may be brought under contextual control. Four undergraduates (two dyads) students participated in the current study. Dyads were instructed to play a game on a computer screen with the goal to earn as many "Congratulations" as possible. An ABABAB reversal design was used. A Lag 1 schedule of cultural consequence delivery for IBC topography was set in the variability (VAR) condition. During the repeated (REP) condition only one IBC topography was reinforced. For one of the two dyads, the variability of IBC topography was brought under contextual control. It is important to explore the behavioral processes at the cultural level to understand prediction and control of cultural phenomena.

Through painting, I use materiality to describe the material world. By rooting my practice in visual culture and art history, I seek to extend the meaning of images beyond their initial form. The coalescing of opposing and complimentary formal elements accentuate the visual and contextual friction. This allows the work to exist in an ambiguous state. Seen together, my works appear disparate, but they suggest alternative meanings through association with one another. The works can exist on their own, but engage in dialogue when juxtaposed against each other. Although about specific occurrences, the works afford the viewer their own interpretations.

Memory Beast was a series of experiments in multispecies collaborative storytelling. A new tool was created, a memory beast, a holotype representing our ideas of specific species, based on memories and drawings collected in participatory research. The fabricated memory beasts, placed next to their biological counterparts, made visible the conflation of living species with personal memory and cultural imagery. Using this new tool, implanted with sonic recordings of cows, the beginnings of an interspecies pidgin language was developed. Memory Beast imagined and enacted new pathways to finite flourishing on a wounded earth, planting story seeds for alternative realities.

Each of my oil or pastel paintings is an observation of seemingly mundane familiar places that I encounter day-to-day. I think of my art as a kind of visual journalism, where I examine common human emotions evoked by a careful consideration of the substance of light interacting with spaces or objects. The naturalistically rendered compositions are cropped and depicted in small fragments, allowing the viewer a brief glimpse into a quiet portrayal of the world. Essentially, my art allows me to share my sensibilities and to connect with others through portraits of ordinary, yet intimate, moments in time.

Peregrine falcon subspecies taxonomy is widely debated due to uncertainty in their evolutionary history and unresolved phylogenetic reconstruction using both morphological and molecular data. Previous genetic work has shown limited support for subspecies taxonomy largely as a result of molecular markers used, potential contemporary gene flow, incomplete lineage sorting, and ancestral polymorphisms. With the advent of next-generation sequencing, the cost of generating large amounts of sequence data has dropped significantly, making whole genome re-sequencing (WGR) studies of non-model organisms more tangible. In this study, WGR methods have been utilized to investigate the phylogenetic relationships among all 20 currently recognized peregrine falcon subspecies. By generating whole-genome data for all 20 subspecies, subspecies specific diagnostic SNPs have been identified to aid in subspecies delimitation. Results of this study broadly support current subspecies, however, reveal that further study is needed to investigate regional relationships among subspecies in Asia, Australia, and western North America. With these results, conservation efforts can be further supported by allowing for accurate delimitation of local subspecies and subspecies boundaries.

The client for this study, the Entheogenic Research, Integration, and Education (ERIE), was interested in the use of anthropological methods to examine the experiences of people who use psychedelics beyond the clinical setting. Through collaborative discussions with the client, we decided that the central questions guiding this research are to understand the various reasons why people consume psychedelic substances across the United States as well as examine the self-reported influences of psychedelics in various areas of participants' life and identity. Participants were recruited using stratified sampling and were given a confidential, online survey that also provided an option to arrange a semi-structured interview. In total, there were 103 completed survey responses and 25 interviews. The results of this research indicate that the reasons for participants' psychedelic use often change over time from strictly recreational or out of curiosity to intentions based on therapeutic and psychospiritual development. Additionally, the majority of both survey and interview participants believed their psychedelic use to have had a transformative influence on their health and well-being, perception of nature, identity, spirituality, and creative expression of art and music. Another theme uncovered in this research is the impacts of punitive drug laws on psychedelic use such as …

This research advances the literature on interracial marriage by using variables that align with the social contact hypothesis. The purpose of this project is to accurately gauge the exact social predictors influencing current attitudes towards Black and White interracial marriage. Multiple regression models containing social contact predictors are analyzed using data from the 2018 General Social Survey. The conclusive review of the literature summarizes age, region, and education as essential social contact predictors of attitudes towards interracial marriage. Therefore, the formulated hypotheses and multiple regression models measure this specific relationship controlling for other predictors such as sex and income. For Whites, the two most significant factors are age and living in the south vs. the west. Interestingly, a college education is not significant. For Blacks, the key contact variable that seems to matter is age. Baby boomers are less likely to favor interracial marriage. Overall, results show areas of convergence. Therefore, one's age is significant predictor for White and Black acceptance. However, it also shows divergence-region appears to only matter for Whites. Accordingly, younger Blacks and Whites were more likely to favor close relatives marrying individuals of the opposite race. Older Blacks and Whites were less likely to support interracial …

In the experimental analysis of behavior, response allocation is typically studied under concurrent interval schedules, with two response alternatives, in a static environment. The natural environment of the unfettered organism, however, is dynamic insofar as even frequently visited environments are rarely identical from encounter to encounter. Additionally, natural environments usually offer more than two concurrently available behaviors that are often scheduled for reinforcement contingent on rate of responding. The purpose of this study was to determine how the addition or removal of a third response alternative affected response allocation between two topographically dissimilar operants on independent concurrent ratio schedules in a dynamic environment. Results indicate that the addition of the third operant served to temporarily suppress response rates of the first two operants but had no or only minor and inconsistent effects on relative allocation. The reintroduction of the third operant in a new location again suppressed response rates in three of four subjects and slightly shifted response allocation for one subject. Highly individual anecdotal patterns could be seen in tangential observations of each of 4 subjects. The results suggest the possibility that new alternatives have temporary effects on response bias, and that these effects may be variable and dependent …

Gordon Allport formalized a theory about intergroup contact, positing that contact between dissimilar groups could be effective in reducing intergroup prejudice. Over half a century later, research suggests that engaging in race talk —conversations about race and racism— can offer benefits such as increased racial literacy and critical consciousness, less intimidation when it comes to addressing race, less fear of differences, and a greater appreciation for people of all cultures and communities. However, race can be a difficult topic to discuss. It typically incites strong emotions, often challenges an individual's lived reality, and triggers anxiety and discomfort for conversational participants. While these barriers to race talk have been well-studied with White participants, little empirical work has been conducted with people of color as a focus. The present study utilized a qualitative, focus-group based methodology with grounded theory analyses to gather information on people of color's barriers to race talk. Results suggest that varied interpersonal contexts — such as when talking to White individuals, other people of color from different racial groups, and their own race— elicit differing levels of comfort and subsequent changes to engagement in race talk. Furthermore, intersecting identities such as gender, sexual orientation, and skin tone further …

The overarching goal of this research was to generate a menu of shape memory alloys (SMAs) actuator materials capable of meeting the demands of aerospace applications. Material requirements were recognized to meet the demand for high temperature SMAs with actuating temperatures above 85 °C and provide material options capable of performing over 100K actuation cycles. The first study is a preliminary characterization for the down selection of Ni-rich NiTiHf15 compositions chosen for a more in-depth examination of the nano-precipitation and evolution of the H-phase. To make this selection, the effect of Ni content in Ni-rich NiTiHf high temperature shape memory alloys (HTSMAs) on processability, microstructure, and hardness was analyzed for three compositions (Ni50.1TiHf15, Ni50.3TiHf15, Ni50.5TiHf15). Each composition was characterized under three conditions: homogenized, 25%, and 50% thickness reduction through hot-rolling. The second study emphasized the processing and aging response of an industrially produced, hot-extruded Ni50.3Ti29.7Hf20 (at%) HTSMA. The samples were sectioned into two halves with half remaining as-extruded and the other half hot-rolled to a 25% reduction in thickness. A portion of both conditions underwent conventional aging for 3 hours at various temperatures ranging from 450-750 °C, and the other portion was pre-aged for 12 hours at 300 °C followed …

The story of Prussia's defeat at the Battles of Jena and Auerstedt and subsequent reform has dominated the historiography of Napoleonic Prussia. While Napoleon has received the vast majority of historical attention, those who have written on Prussia have focused on the Prussian reform movement or the Prussian army's campaigns against Napoleon. These historians present the Prussian army before 1807 as an ossified relic, a hopelessly backward and rigid army commanded by a series of septuagenarians. Apart from the 1806 campaign, these scholars scarcely address the field operations of the Prussian army during the French Wars (1792-1801). This thesis seeks to prove that the Prussian army during the War of the Bavarian Succession and the War of the First Coalition was still an effective fighting force by examining the field operation of the Prussian army from 1778-1793 and the reactions of Prussian thinkers to it. The history of the Prussian army from 1778-1806 challenges the narrative of the army as a force in decline. The Prussian army struggled in the War of the Bavarian Succession, and the war revealed two of its weaknesses, the lack of light troops and an uncoordinated strategic approach. However, many of the problems of the …

Non-imaging Fresnel lenses have been playing an important role in improving the efficiency of the solar energy systems. Many researchers and scientists have devoted their research to optimize the design of the Fresnel lenses. Before it can contribute to energy efficiency increase, a Fresnel lens with optimized design will first need to be fabricated with the most cost-effective method as well as the best quality fabrication as possible. If targeted in a commercial market, feasibility of mass production with a minimum fabrication time would also be a consideration. To bring the design optimization of a Fresnel lens from a conceptual theory to a real-life increase in energy efficiency, the lens needs to be fabricated, tested, compared, and analyzed. This research thesis is intended to explore the performance of the lenses with optimized design through experimental investigations. The design optimization was achieved by a previous PhD student at UNT. A total of six lenses fabricated with four different methods along with two purchased lenses were tested with two different approaches. Multiple testing routes were conducted within a 10-month period to observe the effects of material decomposition and degradation on the lens performance. The resulting experimental data has provided a solid base …

Performance analysis, based on operant analysis of behavior, has been utilized since the 1960s to investigate behavioral skills or deficits in the workplace. One type of analytical tool is Carr et al.'s Performance Diagnostic Checklist- Human Services (PDC-HS). This functional assessment allows investigators to pinpoint causes of performance issues (e.g., a training issue, task clarification/prompting, insufficient resources/materials/processes, or performance consequences/effort/competition). Typically, the PDC-HS is used with clinicians and therapists. The purpose of this study is to extend Carr et al. by evaluating the PDC-HS in assessing the clinical performance of graduate-level research assistants working at a specialized clinic for the assessment and treatment of severe behavior disorders. For each participant, three supervisors, the study investigator and the participants themselves completed the PDC-HS with respect to the performance concern. Results of the PDCH-HS showed variability in congruence across the three groups of respondents. Due to the occurrence of the global coronavirus disease 2019 (COVID-19) pandemic during the study's investigation, the project was modified to assess different clinical performance involving safety procedures. The PDC-HS was re-administered to assess participants' cleanliness behavior and a subsequent targeted intervention was designed. Results showed no improvement of performance for 4/4 participants in the nontargeted intervention for …

My research explores what laws, such as laws surrounding immigration, child custody, and divorce, negatively affect polyamorous individuals in the U.S. and how people's perceptions of barriers differ along lines of gender-sexual-racial-class identities. My applied research is conducted for my client, a CNM-friendly attorney in D.C. I investigate the experience of polyamorous people that use lawyers they perceive as consensually non-monogamous (CNM)-friendly. I probe what it means to be "CNM-friendly," how one promotes oneself as a CNM-friendly lawyer to potential clients and the world at large, and the relationship between being a CNM-friendly lawyer and activism.

Craft beer as a cultural phenomenon coincided with the revitalization of downtown Denton, Texas. Much of the existing literature on craft beer and its relation to place focuses on breweries rather than bars. This exploratory study aims to explain why people consume craft beer, what factors influenced its popularity in Denton despite little beer production, and to explore considerations for the promotion of Denton as a craft beer destination and making downtown an inclusive space. Data was collected through interviews, participant observation, and a survey. Findings indicated that craft beer consumption in Denton is largely related to perceptions of community, localism, and knowledge seeking. The ethos of the craft beer industry closely aligned with participants' perceptions of Denton as a city.
