Looking through a Different Lens, Beyond Censorship: The American Reception of Lady Macbeth of the Mtsensk District
Authors:   , Cassell Holly
Published: February 2025

The censorship of Lady Macbeth of the Mtsensk District is a familiar story to musicologists, but reception of the opera is not frequently mentioned. Examining the reception of a work can bring a work's relative importance into focus. In this thesis, German literary and reception theorist Hans Robert Jauss's model of the horizon of expectations is applied to reviews of American productions of Lady Macbeth. Curiosity about communism following the Great Depression in 1930s, America and American music critics' knowledge that Soviet composers worked for the Soviet regime led to the belief that Lady Macbeth was officially approved export from the Soviet Union. When the article condemning the opera as a Western formalism appeared in the Soviet magazine, Pravda, Americans needed to adjust their understanding of Lady Macbeth as a socialist expression. Following the work's revival in San Francisco in 1981, the influence of Solomon Volkov's Testimony is prevalent in many reviews. Many reviewers use Volkov's narrative of Shostakovich as covert dissident of the Soviet Union to assert that the censorship of the opera was about the content of the plot and not the music. Following the Soviet rejection of the work, American critics tried to claim Shostakovich for the West based on the values of individual freedom and feminism set forth in Lady Macbeth.
The Effect of Instructional Expenditures on College Readiness
Authors:   , Blair Cody L.
Published: February 2025

With limited state and local funds as well as a growing student population, how elected decision makers allocate money to impact college readiness needs to be explored. The purpose of this research study was to explore the impact of instructional expenditures on educational outcomes. This multivariate multiple regression study specifically explored the impact of instructional expenditure ratios and per pupil instructional expenditures of every public school district in Texas on student performance college readiness indicators measured by state assessments (State of Texas Assessment of Academic Readiness [STAAR] Mathematics and English Language Arts [ELA] test scores) and national assessments (American College Test [ACT] and Scholastic Assessment Test [SAT] scores) over a 5-year period. Fifteen different regression models were established with various significant predictors of expenditures and revenue funds. These models explained up to 46% of the variance for college readiness scores over the 5-year period.
A General Approach to Buhlmann Credibility Theory
Authors:   , Yan Yujie
Published: February 2025

Credibility theory is widely used in insurance. It is included in the examination of the Society of Actuaries and in the construction and evaluation of actuarial models. In particular, the Buhlmann credibility model has played a fundamental role in both actuarial theory and practice. It provides a mathematical rigorous procedure for deciding how much credibility should be given to the actual experience rating of an individual risk relative to the manual rating common to a particular class of risks. However, for any selected risk, the Buhlmann model assumes that the outcome random variables in both experience periods and future periods are independent and identically distributed. In addition, the Buhlmann method uses sample mean-based estimators to insure the selected risk, which may be a poor estimator of future costs if only a few observations of past events (costs) are available. We present an extension of the Buhlmann model and propose a general method based on a linear combination of both robust and efficient estimators in a dependence framework. The performance of the proposed procedure is demonstrated by Monte Carlo simulations.
Microwave-Assisted Synthesis and Photophysical Properties of Poly-Imine Ambipolar Ligands and Their Rhenium(I) Carbonyl Complexes
Authors:   , Salazar Garza Gustavo Adolfo
Published: February 2025

The phenomenon luminescence rigidochromism has been reported since the 1970s in tricarbonyldiimine complexes with a general formula [R(CO)3LX] using conventional unipolar diimine ligands such as 2,2;-bipyridine or 1,10-phenanthroline as L, and halogens or simple solvents as X. As a major part of this dissertation, microwave-assisted synthesis, purification, characterization and detailed photoluminescence studies of the complex fac-[ReCl(CO)3L], 1, where L = 4-[4,6-bis(3,5-dimethyl-1H-pyrazol-1-yl]-N,N-diethylbenzenamine are reported. The employment of microwaves in the preparation of 1 decreased the reaction time from 48 to 2 hours compared to the conventional reflux method. Stoichiometry variations allows for selective preparation of either a mononuclear, 1, or binuclear, fac-[Re2Cl2(CO)6], 2, complex. The photophysical properties of 1 were analyzed finding that it possesses significant luminescence rigidochromism. The steady state photoluminescence emission spectra of 1 in solution shift from 550 nm in frozen media to 610 nm when the matrix becomes fluid. Moreover, a very sensitive emission spectral analysis of 0.1 K temperatures steps shows a smooth transition through the glass transition temperature of the solvent host. Furthermore, synthetic modifications to L have attained a family of ambipolar compounds that have tunable photophysical, thermophysical and other material properties that render them promising candidates for potential applications in organic electronics and/or sensors - either as is or for their future complexes with various transition metals and lanthanides.
Intelligence and the Uprising in East Germany 1953: An Example of Political Intelligence
Authors:   , Collins Steven Morris
Published: February 2025

In 1950, the leader of the German Democratic Republic (East Germany), Walter Ulbricht, began a policy of connecting foreign threats with domestic policy failures as if the two were the same, and as if he was not responsible for either. This absolved him of blame for those failures and allowed Ulbricht to define his internal enemies as agents of the western powers. He used the state's secret police force, known as the Stasi, to provide the information that supported his claims of western obstructionism and to intimidate his adversaries. This resulted in a politicization of intelligence whereby Stasi officers slanted information so that it conformed to Ulbricht's doctrine of western interference. Comparisons made of eyewitness' statements to the morale reports filed by Stasi agents show that there was a difference between how the East German worker felt and the way the Stasi portrayed their attitudes to the politburo. Consequently, prior to June 17, 1953, when labor strikes inspired a million East German citizens to rise up against Ulbricht's oppressive government, the politicization of Stasi intelligence caused information over labor unrest to be unreliable at a time of increasing risk to the regime. This study shows the extent of Ulbricht's politicization of Stasi intelligence and its effect on the June 1953 uprising in the German Democratic Republic.
Drum Music: A Performance Guide and Discussion of John Mackey's Influential Concerto for the Modern Percussionist
Authors:   , McWilliams Chris
Published: February 2025

John Mackey is an influential and prolific composer of wind band literature. His focus on and exploration of the percussion section are defining characteristics of his compositional voice. Mackey's concerto for percussion and wind band, "Drum Music," is a perfect example of his exploitation of the myriad timbres available within the percussion family, and also serves to showcase the versatility required of a modern percussionist. This dissertation and accompanying lecture recital provide a comprehensive guide for performers of the work. Major aspects of Mackey's compositional approach are discussed with emphasis placed on his use of percussion throughout his works. Analysis and performance concerns are discussed for each of the concertos three movements, and information is provided on the reduced version of the work prepared as part of this study.
Negotiating Decades of Change in America: The Houston Chinese Traditional Music Group
Authors:   , Mei Yuxin
Published: February 2025

For over two hundred years, Chinese immigrants have brought ancient customs and musical traditions to their new homes in America. As in many immigrant communities, a new heritage that embodies and exhibits both the quintessential features of American culture and genuine Chinese heritage have come together to form new expressive cultures that are uniquely "Chinese American." As the youngest of the major American Chinese immigrant centers, the city of Houston, Texas provides an exemplary example of a distinct cultural cohesion that, in part, resulted from significant cultural and political upheavals in the latter half of the twentieth century. During this era of political unrest, many Chinese people's attitudes towards their traditional culture changed drastically. The Houston Chinese Traditional Music Group (HCTMG) is a Chinese orchestra comprised of amateur and professional musicians ranging in age from 13 to over 60 years old. Performing regularly for the Chinese immigrant population in Houston, HCTMG's take on traditional Chinese music deviates greatly from that of older, more established immigrant communities on the East and West Coasts and in some parts of mainland China. Via participant observation, interviews, and analysis of source materials, this paper examines how changing political and economic climates in China during the 1960s to the 1990s—when the majority of HCTMG musicians lived in China –are reflected in the musical decisions of HCTMG and the greater Houston Chinese immigrant community at large.
Optimization of an SDR Based Aerial Base Station
Authors:   , Mathews Steffy Ann
Published: February 2025

Most times people are unprepared to face natural disasters resulting in chaos, increased number of deaths, etc.Emergency responders need an efficiently working communication network to get in touch with the emergency services like hospitals, police, fire and rescue as well as people who are stranded. Such a network is also the need of the hour for survivors to contact their near and dear ones. One of the major barriers of communication during an emergency is the destruction of network elements. In case the communication devices survive the calamity, odds of the network getting congested are certainly high because almost everyone will be trying to use the same network resources. An important factor when dealing with emergency situations is the calls for an immediate response and an efficient Emergency Communication Systems (ECS). Currently there is a capability gap between existing ECS solutions and what we dream of achieving. Most current solutions do not meet cost or mobility constraints. An inexpensive, portable and mobile system will fulfill this capability gap. The main purpose of this research is to optimize the altitude and received signal strength of an aerial base station to provide maximum radio coverage on the ground as well as propose the best fit radio propagation channel model to carry out the experiment for the current scenario.
The Orchestral Mentality of Johannes Brahms' Piano Sonata No. 3
Authors:   , Hsu Yu-Ching
Published: February 2025

Although the current, exhaustive studies of Brahms' works have covered many aspects of the composer's art, it is still surprising that his large-scale, five-movement Piano Sonata No.3 has in many ways been insufficiently studied by scholars who have emphasized the genre of the piano sonata and the aspect of performance practice over the work's more diverse features. Another reason that this early work has been understudied could in fact be that his later compositions in other genres, such as his symphonies, chamber music or choral music, have been perceived by scholars to represent best his most mature, comprehensive style. This dissertation will therefore examine the orchestral underpinnings of this monumental work which owes most often its already mature artistic essence to Brahms' multi-instrumental approach.
Development and Validation of Measures of Generalization of a Behavior Management Package
Authors:   , Speckin Lauren Marie
Published: February 2025

In order for the benefits of a behavior management skills training program to reach clients, caregivers must use the behavior management skills in the natural environment. The current study took place at a large residential facility for adults with disabilities, in which caregivers had received prior training in which they demonstrated behavior management skills and maintained those skills in contrived role plays. The current study represents a preliminary analysis of generalization of these skills in the natural environment; thus, a measurement system for when caregivers should demonstrate the tools was developed. The specific purpose of this study was to develop and evaluate a program to establish stimulus control over observers' measurement of appropriate behaviors. Researchers systematically developed and validated a measurement system of "good behaviors" that could be used across clients. The process of development and refinement of the measurement system is described. When the system was finalized, three observers' accuracy in using the system was assessed by comparing measured values to that of the code writer. Following feedback on individual instances of behavior, all observers scored the three target behaviors accurately. Ecological validity was assessed by surveying professionals at the facility and ecological validity results suggested a valid measurement system was developed.
A Performer's Guide to Samuil Feinberg's Sonata No. 6: A Window into Russian School Pianism
Authors:   , Georgievskaya Liudmila
Published: February 2025

Samuil Feinberg was an important performing pianist, composer, and one of the protagonists of Russian Piano School. Among his numerous piano compositions, the Sixth Sonata is one of the most complex and illustrative of his deeply personal musical ideas. The following performer's guide offers some ideas on interpreting and performing the sonata from the perspective of Russian school pianism. Having trained in Russia for nearly a decade with two of Feinberg's most eminent disciples and assistants (Tatiana Galitskaya and Liudmila Roschina) makes this author part of living chain back to his pedagogical principles. I will draw upon my knowledge and expertise to illustrate how interpretation of Feinberg's Sonata No. 6 embodies many of the particular and subtle aspects of the Russian piano school technique.
Interacting complex systems: theory and application to real-world situations
Authors:   , Piccinini Nicola
Published: February 2025

The interest in complex systems has increased exponentially during the past years because it was found helpful in addressing many of today's challenges. The study of the brain, biology, earthquakes, markets and social sciences are only a few examples of the fields that have benefited from the investigation of complex systems. Internet, the increased mobility of people and the raising energy demand are among the factors that brought in contact complex systems that were isolated till a few years ago. A theory for the interaction between complex systems is becoming more and more urgent to help mankind in this transition. The present work builds upon the most recent results in this field by solving a theoretical problem that prevented previous work to be applied to important complex systems, like the brain. It also shows preliminary laboratory results of perturbation of in vitro neural networks that were done to test the theory. Finally, it gives a preview of the studies that are being done to create a theory that is even closer to the interaction between real complex systems.
Transfer of Learning in a K-8 STEM Academy Project Based Learning (PBL) Environment
Authors:   , Fuller Mary A.
Published: February 2025

The multiple case study investigated levels and types of transfer observed in a K-8 STEM (science, technology, engineering, math) academy in a project-based learning (PBL) environment. The academy was constructed two years prior to the study and conducive to PBL instruction. The students and teachers were in the second year of using PBL in the subject of science at the time of the study. The grade levels observed were second, fourth, and sixth grade and each grade level had three PBL units examined from the beginning to the end of the unit. The nine case studies, from the three different grade levels, were observed to identify Haskell's levels and types of transfer as determined by project requirements, observation of students, completed projects, and student interviews. The findings from this study showed that while projects moved the students beyond knowledge acquisition to application of knowledge in completed projects such as books, films, dances, etc., higher levels of transfer and more types of transfer were not evident. Therefore, based on the results of this study, the evidence of lower levels of transfer suggests that the PBL units, though inventive and potentially valuable to student learning, were not designed for higher levels of transfer.
A Conjugate Arrangement for Measuring Commercial Viewing
Authors:   , Morgan Amber Denise
Published: February 2025

Commercial viewing was measured by a conjugate arrangement for 1 female and 3 male participants. Reinforcing qualities were evaluated according to screen variations and ratings. Subjects changed the screen clarity via knob pressing either making the screen more or less transparent, translucent or opaque based on commercial interest. Results were conducive to participant attentiveness or indifference to commercial viewing. Experimenter was able to identify the commercials that grasped and maintained the participants' viewing behavior. Conceptually this conjugate arrangement could enhance eye tracking technology to improve marketing and advertising strategies. This experiment yield results that suggest a more concrete analysis of consumer response to visual stimuli that maintains attending.
African American Soldiers in the Philippine War: An Examination of the Contributions of Buffalo Soldiers during the Spanish American War and Its Aftermath, 1898-1902
Authors:   , Redgraves Christopher M.
Published: February 2025

During the Philippine War, 1899 – 1902, America attempted to quell an uprising from the Filipino people. Four regular army regiments of black soldiers, the Ninth and Tenth Cavalry, and the Twenty-Fourth and Twenty-Fifth Infantry served in this conflict. Alongside the regular army regiments, two volunteer regiments of black soldiers, the Forty-Eighth and Forty-Ninth, also served. During and after the war these regiments received little attention from the press, public, or even historians. These black regiments served in a variety of duties in the Philippines, primarily these regiments served on the islands of Luzon and Samar. The main role of these regiments focused on garrisoning sections of the Philippines and helping to end the insurrection. To carry out this mission, the regiments undertook a variety of duties including scouting, fighting insurgents and ladrones (bandits), creating local civil governments, and improving infrastructure. The regiments challenged racist notions in America in three ways. They undertook the same duties as white soldiers. They interacted with local "brown" Filipino populations without fraternizing, particularly with women, as whites assumed they would. And, they served effectively at the company and platoon level under black officers. Despite the important contributions of these soldiers, both socially and militarily, little research focuses on their experiences in the Philippines. This dissertation will discover and examine those experiences. To do this, each regiment is discussed individually and their experiences used to examine the role these men played in the Philippine War. Also addressed is the role ideas about race played in these experiences. This dissertation looks to answer whether or not notions on race played a major role in the activities of these regiments. This dissertation will be an important addition to the study of the Philippine War, the segregated U. S. Army, and African American history in the modern period.
How eHealth Literacy Impacts Patient-Provider Relationships: A Study on Trust, Self-Care, and Patient Satisfaction
Authors:   , Cheun Jacquelyn
Published: February 2025

It has been well established, in the literature, the association between low health literacy rates and poor health outcomes. With the increase of technology dependence, more people are using the internet to look up health information. Research has shown that shared decision making between providers and patients can improve patients' health outcomes. This research aims to examine whether electronic health (eHealth) literacy impacts patient-provider relationships. This research will also examine how geography specifically state residency impacts eHealth literacy rates. Data collected from a national sampling of online health and medical information users who participated in the Study of Health and Medical Information in Cyberspace (N=710) is used to construct structural equation models from SPSS AMOS v. 20.0. After path analysis, the results shown that white males with higher education were more likely to have higher eHealth literacy rates and that eHealth literacy rates are associated with better self-care, higher patient satisfaction and increased trust in provider. Also, state residency does not have an impact on eHealth literacy rates. eHealth literacy will be significant in patient-provider relationships. Program development should be established on focusing on eHealth literacy across the lifespan. Also, it will be important to review federal policy on technology disbursements in order to achieve national goals on eHealth literacy rates.
Quia Emptores, Subinfeudation, and the Decline of Feudalism in Medieval England: Feudalism, it is Your Count that Votes
Authors:   , Garofalo Michael D.
Published: February 2025

The focus of this thesis is threefold. First, Edward I enacted the Statute of Westminster III, Quia Emptores in 1290, at the insistence of his leading barons. Secondly, there were precedents for the king of England doing something against his will. Finally, there were unintended consequences once parliament passed this statute. The passage of the statute effectively outlawed subinfeudation in all fee simple estates. It also detailed how land was able to be transferred from one possessor to another. Prior to this statute being signed into law, a lord owed the King feudal incidences, which are fees or services of various types, paid by each property holder. In some cases, these fees were due in the form of knights and fighting soldiers along with the weapons and armor to support them. The number of these knights owed depended on the amount of land held. Lords in many cases would transfer land to another person and that person would now owe the feudal incidences to his new lord, not the original one. This amount collected by the lord effectively reduced the payments to the original lord. During the early Middle Ages, feudal incidences began to change to a monetary exchange which would be used to purchase outside knights and soldiers. At this time, lords throughout England were losing revenue because of the subinfeudation. The Statute of Quia Emptores stopped subinfeudation and prevented lords from transferring land to another by any method except for subsitution. The statute itself was short but it covered all land in England. I will argue in my thesis that this statute had more to do with the ending of feudalism than any other single event. I will further argue that it was not King Edward I's intention to end feudalism. The ending of feudalism was an unintended consequence of the enactment of his statute in 1290.
The Influence of Social and Cultural Factors on Alcohol Use and Abuse among a Sample of Young Males in the Army
Authors:   , Short J. Rollin
Published: February 2025

The purpose of this qualitative study was to understand the social, cultural, and structural factors that contribute to or inhibit alcohol use and abuse in the Army among young males, unmarried or married without a present spouse. Seventeeen single, or separated, young male soldiers stationed at Fort Bragg Army Base were interviewed to provide insight into the research questions. Soldiers were largely located through face-to-face canvassing. The interviews, which lasted from 45 to 90 minutes, took place face-to-face and were then transcribed. Interviews were analyzed using grounded theory approach by locating patterns, themes and relationships to come to generalizations. The themes that emerged from the interviews include: 1) stresses of army work/life; 2) social/entertainment use; 3) tradition/brotherhood/entitlement; 4) fear/consequences; 5) impressionable youth; 6) treatment. While the themes which emerged were reported in discrete terms, there was overlap in them. The functional aspect of alcohol use to these soldiers mixed with the impact of social interaction influencing their use served to encourage and further the use of alcohol. The drinking patterns of young male soldiers can be seen to exist on a continuum of either social integration or social stress, in line with Durkheim's conception of suicide, with the existence of being on either end of these continuums leading to excessive alcohol use. The findings confirm Durkheim's conception of social order in leading to unhealthy responses and indicate the Army needs to address the role and impact of the greater social environment in leading to alcohol misuse among young male soldiers.
Are Streams Protected? Outcomes of Environmental Regulation
Authors:   , Rowen Zachary
Published: February 2025

Urban areas experience the loss of natural stream channels through conversion to artificial conveyances. This process tends to target headwater and other low order streams. The purpose of this study is to determine the patterns of stream loss in Denton, Texas, and explore the regulatory structure that manages these streams. Historic and current maps and stream data are used to map Denton's streams and categorize them according to their vertical connectivity as: 1) "intact", streams that are open to the atmosphere and connect to groundwater; 2) "concrete", channelized streams open to the atmosphere but cut off from groundwater; and 3) "buried", streams disconnected from the atmosphere and groundwater. A review of federal, state, and local regulatory codes and interviews with local government officials and other stakeholders elucidates stream management in Denton. Results from these analyses reveal high rates of stream loss in the urban center with low rates overall. The federal Clean Water Act and the local Environmentally Sensitive Areas code serve as the primary protective measures for natural streams. These regulations discourage stream impacts through expensive and complex permitting requirements. However the policies allow minor impacts which may cause cumulative effects. This study aims to inform future policy-making decisions and contribute to the knowledge of the environmental regulation of streams.
A Mixed Methods Approach to Exploring Social Support and Resilience in Coping with Stigma and Psychological Distress among HIV-Positive Adults
Authors:   , Fritz Sarah-mee Hesse
Published: February 2025

Since its emergence in the U.S., HIV has been a stigmatized illness. People living with HIV (PLH) are a minority and prone to psychological distress and poor mental health outcomes due to HIV-related stigma. PLH who identify with another minority group in addition to being HIV-positive (e.g., gay, African-American) experience multiple forms of oppression or layered stigma. Affirmative social support and resilience are negatively associated with HIV-stigma and are important coping resources for PLH. We used an explanatory sequential mixed methods design study involving a quantitative survey phase and a qualitative interview phase. We explored whether social support and resilience (Positive Psychological Resources) mediate or moderate the relationship between HIV Stigma and Psychological Distress among HIV-positive adults using partial least squares (PLS) path modeling and multiple regressions. Via PLS, we found Positive Psychological Resources partially mediated the relationship between HIV Stigma and Psychological Distress: the path between HIV Stigma and Psychological distress reduced (from t = 5.49, p = .000 to t = 2.39, p = .000) but remained statistically significant. Similarly, via regression, the Sobel test was significant (Sobel = .26, SE = .07, z = 3.63, p = .000). However, moderation was not found (HIV Stigma x Positive Psychological Resources β = .05, t = .66, p = .508). Overall, our quantitative survey and qualitative interview data were consistent. We anticipate that our findings will inform strengths-based therapeutic interventions to mitigate stress and stigma among PLH.
Educational Uplift along the U.S.-Mexico Border: How Students, Families, and Educators Cultivate a College-Going Culture in Contested Terrain
Authors:   , Sanchez Nydia C.
Published: February 2025

Using critical race theory and LatCrit as conceptual frameworks, I conducted a qualitative instrumental case study of a cadre of self-identified Mexican-American and Hispanic college students who bring college knowledge, goodwill, and aid to their border town communities. The purpose of this study was to explore how college knowledge and other forms of academic capital are transmitted and co-constructed in the contested terrain of the borderlands. Primary data sources included semi-structured interviews, participant and non-participant observation, and personal artifacts (e.g. newspaper articles, college admissions essays, social media, etc.) collected from 17 full-time undergraduate student participants, 11 males and 6 females, ranging from 19 to 22 years old, who were active members of the Gates Millennium Scholars Program. Supplemental data sources included semi-structured interviews with 23 family members and 9 educators identified by student participants, as well as a review of public records regarding student participant's border town communities (e.g. newspaper articles, census data, educational statistics, etc.). Findings detail how this group of college students manages the 'scholar' distinction in their hometown and utilizes distinct methods to promote academic capital formation. Specifically, this study delineates the following four types of scholars: (1) pioneers, (2) guardians, (3) ambassadors, and (4) advocates. Ultimately, this research highlights the importance of college students' ingenuity in response to enduring system inequality in higher education, particularly along the U.S.-Mexico border, with implications for research theory, policy, and practice.
Laser Additive Manufacturing of Magnetic Materials
Authors:   , Mikler Calvin V.
Published: February 2025

A matrix of variably processed Fe-30at%Ni was deposited with variations in laser travel speeds as well and laser powers. A complete shift in phase stability occurred as a function of varying laser travel speed. At slow travel speeds, the microstructure was dominated by a columnar fcc phase. Intermediate travel speeds yielded a mixed microstructure comprised of both the columnar fcc and a martensite-like bcc phase. At the fastest travel speed, the microstructure was dominated by the bcc phase. This shift in phase stability subsequently affected the magnetic properties, specifically saturation magnetization. Ni-Fe-Mo and Ni-Fe-V permalloys were deposited from an elemental blend of powders as well. Both systems exhibited featureless microstructures dominated by an fcc phase. Magnetic measurements yielded saturation magnetizations on par with conventionally processed permalloys, however coercivities were significantly larger; this difference is attributed to microstructural defects that occur during the additive manufacturing process.
It's All Coming Back to You: 1980s Retro Film Culture and the Masculinity of Cult
Authors:   , Collins Ryan William
Published: February 2025

The 1980s is a formative decade in American history. America sought to reestablish itself as a global power and to reassert the dominant ideology of white, patriarchal capitalism. Likewise, media producers in the 1980s sought to reassert the dominance of the white, male, muscled body in filmic representations. The identity politics of the 1980s and the depictions of the white, muscled body once prominent in the 1980s have been the site of conservative nostalgia for a young, male-dominated, cult audience that is a subset of a larger cultural trend known as retro film culture. This thesis provides historical context behind the populist 1980s B-action films from Cannon Group, Inc that celebrate violent masculinity in filmic representations with white, male action heroes. Equally important is the revival of VHS collecting and how this 1980s-inspired subculture reinforces white, patriarchal capitalism through the cult films they valorize and their capitalistic trading practices despite their claims of oppositionality against mainstream taste and Hollywood films. Lastly, this thesis reveals how a new cycle of contemporary films primarily produced outside of Hollywood reasserts and celebrates the dominance of the white, male, muscled body in filmic representations despite a postmodern and hyperconscious exterior. Overall, I argue how these areas of nostalgia are distinct, yet not unrelated, because they reassert white, patriarchal capitalism through the revival of conservative nostalgia for the 1980s.
Crystallographic Complex Reflection Groups and the Braid Conjecture
Authors:   , Puente Philip Carvajal
Published: February 2025

Crystallographic complex reflection groups are generated by reflections about affine hyperplanes in complex space and stabilize a full rank lattice. These analogs of affine Weyl groups have infinite order and were classified by V.L. Popov in 1982. The classical Braid theorem (first established by E. Artin and E. Brieskorn) asserts that the Artin group of a reflection group (finite or affine Weyl) gives the fundamental group of regular orbits. In other words, the fundamental group of the space with reflecting hyperplanes removed has a presentation mimicking that of the Coxeter presentation; one need only remove relations giving generators finite order. N.V Dung used a semi-cell construction to prove the Braid theorem for affine Weyl groups. Malle conjectured that the Braid theorem holds for all crystallographic complex reflection groups after constructing Coxeter-like reflection presentations. We show how to extend Dung's ideas to crystallographic complex reflection groups and then extend the Braid theorem to some groups in the infinite family [G(r,p,n)]. The proof requires a new classification of crystallographic groups in the infinite family that fail the Steinberg theorem.
Comparing Three Approaches for Handling a Fourth Level of Nesting Structure in Cluster-Randomized Trials
Authors:   , Glaman Ryan
Published: February 2025

This study compared 3 approaches for handling a fourth level of nesting structure when analyzing data from a cluster-randomized trial (CRT). CRTs can include 3 levels of nesting: repeated measures, individual, and cluster levels. However, above the cluster level, there may sometimes be an additional potentially important fourth level of nesting (e.g., schools, districts, etc., depending on the design) that is typically ignored in CRT data analysis. The current study examined the impact of ignoring this fourth level, accounting for it using a model-based approach, and accounting it using a design-based approach on parameter and standard error (SE) estimates. Several fixed effect and random effect variance parameters and SEs were biased across all 3 models. In the 4-level model, most SE biases decreased as the number of level 3 clusters increased and as the number of level 4 clusters decreased. Also, random effect variance biases decreased as the number of level 3 clusters increased. In the 3-level and complex models, SEs became more biased as the weight level 4 carried increased (i.e., larger intraclass correlation, more clusters at that level). The current results suggest that if a meaningful fourth level of nesting exists, future researchers should account for it using design-based approach; the model-based approach is not recommended. If the fourth level is not practically important, researchers may ignore it altogether.
Evaluating the Role of UV Exposure and Recovery Regimes in PAH Photo-Induced Toxicity to Daphina Magna
Authors:   , Gnau Jennifer Leigh
Published: February 2025

Polyaromatic hydrocarbons (PAHs) are contaminants synthesized through incomplete combustion of carbon based substances. PAHs are known to be photodynamic and toxicity increases exponentially when in contact with ultraviolet radiation (UV). The effect of UV absent recovery periods and potential for latent toxicity during photo-induced toxicity are previously unknown and are not included within the toxicity model. Results of equal interval tests further support the current reciprocity model as a good indicator of PAH photo-induced toxicity. Interval test results also indicate a possible presence of time-dependent toxicity and recovery thresholds and should be included into toxicity risk assessments. Moreover, results of latent effects assays show that latent mortality is a significant response to PAH photo-induced toxicity and should be included into toxicity risk assessments. The present research demonstrates that UV exposure time rate is a significant driving force of PAH photo-induced toxicity.
Location Estimation and Geo-Correlated Information Trends
Authors:   , Liu Zhi
Published: February 2025

A tremendous amount of information is being shared every day on social media sites such as Facebook, Twitter or Google+. However, only a small portion of users provide their location information, which can be helpful in targeted advertising and many other services. Current methods in location estimation using social relationships consider social friendship as a simple binary relationship. However, social closeness between users and structure of friends have strong implications on geographic distances. In the first task, we introduce new measures to evaluate the social closeness between users and structure of friends. Then we propose models that use them for location estimation. Compared with the models which take the friend relation as a binary feature, social closeness can help identify which friend of a user is more important and friend structure can help to determine significance level of locations, thus improving the accuracy of the location estimation models. A confidence iteration method is further introduced to improve estimation accuracy and overcome the problem of scarce location information. We evaluate our methods on two different datasets, Twitter and Gowalla. The results show that our model can improve the estimation accuracy by 5% - 20% compared with state-of-the-art friend-based models. In the second task, we also propose a Local Event Discovery and Summarization (LEDS) framework to detect local events from Twitter. Many existing algorithms for event detection focus on larger-scale events and are not sensitive to smaller-scale local events. Most of the local events detected by these methods are major events like important sports, shows, or big natural disasters. In this work, we propose the LEDS framework to detect both bigger and smaller events. LEDS contains three key steps: 1) Detecting possible event related terms by monitoring abnormal distribution in different locations and times; 2) Clustering tweets based on their key terms, time, and location distribution; and 3) Extracting descriptions include time, location, and key sentences of local events from clusters. The model is evaluated on a real-world Twitter dataset with more than 60 million tweets. The analysis of Twitter data can help to predict or explain many real-world phenomena. The relationships among events in the real world can be reflected among the topics on social media. In the third task, we propose the concept of topic association and the associated mining algorithms. Topics with close temporal and spatial relationship may have direct or potential association in the real world. Our goal is to mine such topic associations and show their relationships in different time-region frames. We propose to use the concepts of participation ratio and participation index to measure the closeness among topics and propose a spatiotemporal index to calculate them efficiently. With the topic filtering and the topic combination, we further optimize the mining process and the mining results.
Practices that Influence Instructional Coaches' Perceptions of Effectiveness

As instructional coaches are being implemented across the country, their purpose is reviewed, as well as which types of instructional coaching tend to have the most impact on teachers' instructional growth. In this study, I explored instructional coaching and coaches' perceived effectiveness as they work with teachers. A look at the effect of non-evaluative feedback with an instructional coach, and how that helps sustain teachers' pedagogical practice, is taken into consideration as coaches' work towards developing teacher efficacy. I examined instructional coaching through the conceptual framework of professional development and change. This qualitative study included a focus group, personal narratives, and individual interviews to analyze the components of successful instructional coaching models, and how well instructional coaches feel supported as they work with teachers. Findings demonstrated that instructional coaches perceive their work with teachers to be effective and provided information on the practices and conditions that surround their work. The information gained from the study provides a resource for district leaders to evaluate a current coaching model program, or implement a new coaching model program, within their district.

Exposing the Spectacular Body: The Wheel, Hanging, Impaling, Placarding, and Crucifixion in the Ancient World
Authors:   , Foust Kristan Ewin
Published: February 2025

This dissertation brings the Ancient Near Eastern practice of the wheel, hanging, impaling, placarding, and crucifixion (WHIPC) into the scholarship of crucifixion, which has been too dominated by the Greek and Roman practice. WHIPC can be defined as the exposure of a body via affixing, by any means, to a structure, wooden or otherwise, for public display (Chapter 2). Linguistic analysis of relevant sources in several languages (including Egyptian hieroglyphics, Sumerian, Hebrew, Hittite, Old Persian, all phases of ancient Greek, and Latin) shows that because of imprecise terminology, any realistic definition of WHIPC must be broad (Chapter 3). Using methodologies and interdisciplinary approaches drawn from art history, archaeology, linguistic analysis, and digital humanities, this work analyzes scattered but abundant evidence to piece together theories about who was crucified, when, how, where, and why. The dissertation proves that WHIPC records, written and visual, were kept for three primary functions: to advertise power, to punish and deter, and to perform magical rituals or fulfill religious obligations. Manifestations of these three functions come through WHIPC in mythology (see especially Chapter 4), trophies (Chapter 5), spectacles, propaganda, political commentary, executions, corrective torture, behavior modification or prevention, donative sacrifices, scapegoat offerings, curses, and healing rituals. WHIPC also served as a mode of human and animal sacrifice (Chapter 6). Regarding the treatment of the body, several examples reveal cultural contexts for nudity and bone-breaking, which often accompanied WHIPC (Chapter 7). In the frequent instances where burial was forbidden a second penalty, played out in the afterlife, was intended. Contrary to some modern assertions, implementation of crucifixion was not limited by gender or status (Chapter 8). WHIPC often occurred along roads or on hills and mountains, or in in liminal spaces such as doorways, cliffs, city gates, and city walls (Chapter 9). From the Sumerians to the Romans, exposing and displaying the bodies consistently functioned as a display of power, punishment and prevention of undesirable behavior, and held religious and magical significance. Exposure punishments have been pervasive and global since the beginning of recorded time, and indeed, this treatment of the body is still practiced today. It seems no culture has escaped this form of physical abuse.
Economic Resilience, Disasters, and Green Jobs: An Institutional Collective Action Framework
Authors:   , Ismayilov Orkhan M.
Published: February 2025

This dissertation is about economic resilience of local governments to natural disasters. Specifically, the dissertation investigates resilience on regional level. Moreover, the dissertation also investigates growth in the green job sector in local governments. The findings indicate that local governments working with each other helps green job creation. In addition, the dissertation finds that green jobs, following disasters, experience three percent growth. This dissertation is important because it investigates the relationship between climate- related disasters and green jobs, which is an area that is under-investigated.
Return to Sport: Improving Athletes' Confidence and Mindset Post-ACL Surgery
Authors:   , Sheinbein Shelly T.
Published: February 2025

This study explored the impact of three psychological interventions over seven weeks - goal setting (GS), GS and imagery (IM), and GS and mindful self-compassion (MSC) - on 20 athletes' (Mage = 16.75 years) pain, cognitive appraisal, depression reinjury anxiety, psychological readiness to return to sport, and range of motion (ROM). IM and GS interventions have demonstrated initial effectiveness; however, no study has examined MSC in relation to post-ACL recovery. All athletes experienced significant decrease in pain (F(2) = 97.30, p = .000) from Week 1 to Week 7 and a significant increase in ROM from Week 2 to Week 7 (F(1) = 77.93, p = .000). All athletes experienced significantly higher depression at Week 1 compared to both Week 2 and Week 7 (F(2) = 9.01, p = .001), and significantly higher difficulty coping with their injury at Weeks 1 and 2 compared to Week 7 (F(2) = 6.32, p = .005). There were no statistically significant effects found between the intervention groups at Weeks 1, 2, and 7. However there were moderate effect sizes between interventions which suggest MSC and IM could help athletes cope with their injury during the first few weeks after surgery, and GS may contribute towards less depression at seven weeks post-surgery. Limitations include small sample size, low power, and use of self-report measures. Results have implications for orthopedic surgeons, physical therapists, and health professionals working with athletes recovering from serious sport injury.
