Neurotoxic Effects of Polycyclic Aromatic Hydrocarbons in Vertebrates, from Behavioral to Cellular Levels

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental toxicants found in anthropogenic mixtures such as crude oil, air pollution, vehicle exhaust, and in some natural combustion reactions. Single PAHs such as benzo[a]pyrene (BaP) also impact fish behavior when animals are exposed in early life stages and for short periods of time. Aquatic animals such as fish may encounter BaP through road runoff and oil spills, but few studies have examined the impact of aqueous exposure on adult fish, and fewer have examined the resulting fitness-relevant behavioral consequences of BaP and PAH mixtures and their long-term persistence. This dissertation targets this gap in the literature by examining how aqueous exposure to BaP influences anxiety-like behavior, learning, and memory in adult zebrafish, and how parental exposure to the PAH mixture, crude oil, combined with hypoxia affects social and exploratory behavior in unexposed larval zebrafish. We found that learning and memory were not affected by 24 hour exposure to BaP, that anxiety-like behavior was minimally affected, and that locomotor parameters such as distance moved and times spent in darting and immobile states were significantly altered by exposure to BaP. Additionally, we found that parental exposure to crude oil and hypoxia decreased larval velocity. Additionally, …

Exploring Uses of Automated Essay Scoring for ESL: Bridging the Gap between Research and Practice (open access)

Exploring Uses of Automated Essay Scoring for ESL: Bridging the Gap between Research and Practice

Manually grading essays and providing comprehensive feedback pose significant challenges for writing instructors, requiring subjective assessments of various writing elements. Automated essay scoring (AES) systems have emerged as a potential solution, offering improved grading consistency and time efficiency, along with insightful analytics. However, the use of AES in English as a Second Language (ESL) remains rare. This dissertation aims to explore the implementation of AES in ESL education to enhance teaching and learning. The dissertation presents a study involving ESL teachers who learned to use a specific AES system called LightSide, a free and open text mining tool, to enhance writing instruction. The study involved observations, interviews, and a workshop where teachers learned to build their own AES using LightSide. The study aimed to address questions related to teacher interest in using AES, challenges faced by teachers, and the influence of the workshop on teachers' perceptions of AES. By exploring the use of AES in ESL education, this research provides valuable insights to inform the integration of technology and enhance the teaching and learning of writing skills for English language learners.

Household Displacement after Hurricane Harvey: Decisions, Destination Choice, and Displacement Patterns (open access)

Household Displacement after Hurricane Harvey: Decisions, Destination Choice, and Displacement Patterns

The thesis examines post-event displacement of households in the year following Hurricane Harvey. Using data gathered from a three-page mail survey conducted approximately 1-year after the storm, this study examines two primary research objectives. First this thesis aims to identify variables that predict displacement or non-displacement after the disaster. Second, this study explores patterns in the destination and duration of displaced households following Hurricane Harvey. Logistic regression analyses were used to examine the extent to which household composition characteristics and level of damage sustained during Hurricane Harvey predicted post-disaster displacement. Next, independent sample t-tests and descriptive statistical analyses were used to identify patterns in the destination of post-event relocations. Research findings indicate in the overall binary logistic regression model that after Hurricane Harvey, being White, level of home damage, wind damage, and number of days a member of the household returned home post-Harvey increased the likelihood of a household being displaced. Analysis of the survey responses also indicated that many households made multiple moves following Hurricane Harvey and specifically, displaced households were more likely to stay with a friend or relative. Additionally, this study found that with each additional relocation, the duration of stay at each destination increased while the …

Linkage of the Nitrilase-Encoding Nit1C Gene Cluster to Cyanotrophy in Acinetobacter haemolyticus

The Nit1C cluster is a conserved gene cluster of seven genes that confers bacterial growth on cyanide as the sole nitrogen source. Bacteria with this ability are referred to as cyanotrophs. To date, the linkage between Nit1C and cyanotrophy has only been demonstrated for environmental isolates but the cluster also exists in certain medically related bacteria. In this study, a nosocomial isolate, Acinetobacter haemolyticus ATCC 19194, carrying Nit1C also displayed the ability to grow on cyanide. Growth on cyanide was accompanied by the induction of the cluster as was the mere exposure of cells to cyanide. Expression of the cluster was determined by measuring the activity of the nitrilase (NitC) coded for by the cluster and by transcriptional analysis (qRT-PCR). However, a disconnect between nitC message and NitC protein was observed depending on the phase of the growth cycle, the disconnect being related to proteolytic digestion of the NitC protein. Ironically, the cluster was also discovered to be upregulated in the absence of cyanide under nitrogen starvation conditions paralleling biofilm formation. The basis of the genetic linkage to cyanotrophy is not understood but taken together with results showing that nitrogen starvation and biofilm formation are also physiologically associated with Nit1C …

The Good and the Bad Sides of the Protest: Framing Abortion Rights Protests in Photojournalism (open access)

The Good and the Bad Sides of the Protest: Framing Abortion Rights Protests in Photojournalism

In both Mexico and the U.S., abortion rights protests have been taking place in recent years, but while Mexico is moving forward with the legalization of abortion, the U.S. is going in the opposite direction with the overturning of Roe v. Wade. Through framing, journalists select salient information, shaping audiences' understandings of social movements. The protest paradigm suggests that due to journalistic norms and routines, journalists tend to focus on disruptive acts, which can stigmatize the protest. Additionally, scholars have stated that men and women photojournalists have different approaches to covering certain topics. This cross-national research combined a content analysis of photographs in U.S. and Mexican media with in-depth interviews with photojournalists to determine if photojournalists in each country are reproducing the protest paradigm and if there are gendered differences in how they photograph abortion rights protests. The results revealed that women and men photograph differently, with women capturing more intimate photos; however, photojournalists' gendered experiences are also influenced by how protesters perceive them. Furthermore, the study suggests that photojournalists from both countries are questioning objectivity and are attempting to move away from the protest paradigm. This research provides valuable insights into visual framing theory, protest news coverage, and gendered …

Exploring the Dimensions of the Learning Organization Questionnaire (DLOQ) for Startup Learning Environments

Although the Dimensions of the Learning Organization Questionnaire (DLOQ) has been widely accepted by the HRD community, it has not been tested in a startup context for reliability. The purpose of the current study is to explore if the DLOQ is a reliable instrument for startups to help them be more successful. The current study seeks to address some of the questions, which have been posed by previous researchers. The study utilizes a mixed-method design applying Cronbach alpha values to check the reliability of the instrument in a startup learning environment, with more than 600 participants and 42 startup businesses at a university in the Mountain West. The study uses objective financial measures for startup firms to explore the correlation between the seven dimensions of the DLOQ and startup companies at the university. Cronbach alphas for the instrument measured at the .80 level or higher. Four of the dimensions were found to be statistically significant resulting in a model that accounted for 30% of the variance in predicted Operating Income (p<.004) and 29% of the variances in predicted Net Income (p<.003). The study also uses qualitative analysis to explore what activities relate to the seven dimensions of the DLOQ, and …

Structural Design and Its Impact on Thermal Efficiency and Corrosion of All-Aluminum Microchannel Heat Exchangers

In this study, high-fidelity conjugate heat transfer simulations are used to model a micro-channel heat exchanger (MCHE) in a crossflow to study its thermal-hydraulic performance. This study considers three different microchannels (internal flow) geometries (circular, triangular, and square) with louver-shaped fins. The local flow field showed a strong coupling between the microchannel flow, solid domain, and crossflow. The flow separation and wake regions formed near MCHE resulted in a large variation in the velocity field and temperature in the crossflow. The wake region had a significant spanwise variation due to its interaction with fins, which also causes variations in the thermal boundary layer. The heat conduction in the solid structure provided a non-uniform temperature field with a higher temperature near the microchannel and a slightly lower temperature near the surface exposed to the crossflow. The microchannel flow analysis showed that the internal geometry affects the pressure drop, which is highest for the triangular MCHE and lowest for the circular MCHE. However, the microchannel flow temperature change was relatively similar for all microchannels. Results showed that for the same volume of the microchannel, the circular shape microchannel has a higher performance index value than the triangular and square shapes. This study …

Devotio Moderna and Erasmus: Transforming Piety

The relationship between Erasmus of Rotterdam and the religious movement called the Devotio Moderna, especially the latter's relevance to Erasmian piety, has been a somewhat contentious historiographical issue. This thesis examines that relationship, and asserts that the Devotio Moderna was a crucial formative aspect of Erasmus' religiosity. However, its relevance ought not be overstated, due to the humanist's significant developments away from his spiritual forerunners.

The Effects of Prompts on Variability in Children with ASD (open access)

The Effects of Prompts on Variability in Children with ASD

The concept of "creativity" has been studied under the perspective of variability in behavior analysis. Creativity and variable responding contributes to problem solving in novel situations, learning new responses in different environments, and promote interactions that would otherwise be prohibited by repetitive behaviors and routines. During childhood, play contributes to the emergence of creativity and variability. Children develop many skills that are important to their lives while engaging in play behaviors. Some of those skills include self-advocacy, communication, and problem solving. Researchers have investigated different methods to promote variable play skills in children with autism spectrum disorder (ASD). There is limited research on prompting as an isolated variable in increasing variability in play responses. The purpose of this study was to investigate the effects of prompting on variable play skills. Results indicated that verbal instructions and modeling were effective in increasing variable play responses. Both participants displayed a sustained increase in novel item engagement when exposed to prompting.

Sustainable Healthcare Provider OUD Assessment and Management in Rural Native American Communities (RNACs): Prevention, Treatment, and Recovery Approaches (open access)

Sustainable Healthcare Provider OUD Assessment and Management in Rural Native American Communities (RNACs): Prevention, Treatment, and Recovery Approaches

In the US, rural Native American communities (RNACs) experience excess morbidity in mental health disorders and mortality from opioid use disorder (OUD). This study used mixed methods to evaluate and analyze the primary data from 76 healthcare providers (HPs) from 24 states across the US (physicians = 7%), to identify HP knowledge and training regarding available prevention, treatment, and recovery (PTR) programs in treating OUD, assessment and management skills, and networking and collaboration capacity among the RNACs they serve. The HP completed the Opioid Survey for Health Care Providers online. A majority of HPs reported a need for knowledge and training regarding OUD treatments (92%). Less than half of the HPs provide intensive outpatient treatment; 40% contracted out for medication assisted treatment/medications for opioid use disorder (MAT/MOUD) services. Recovery support was low at 33% for adults and 38% for youth. HPs reported use of Narcan to be effective in reversing overdose (87%). Qualitative responses supported survey findings and described barriers, including lack of resources, inadequate staffing, insufficient funding, lack of training and OUD knowledge, stigma, and lack of tribal involvement and support. The study findings indicate HPs' need for information and training about OUD and networking and collaboration of healthcare …

An Examination of Communication Patterns, Relationship Satisfaction, and Mental Health Symptoms in IPV-Exposed Women With and Without a History of Child Abuse (open access)

An Examination of Communication Patterns, Relationship Satisfaction, and Mental Health Symptoms in IPV-Exposed Women With and Without a History of Child Abuse

Extant research suggests communication styles (CS) such as constructive communication (CC) to be associated positively with relationship satisfaction (RS) and negatively with mental health (MH) whereas self-demand / partner withdraw (SD/PW) communication is associated negatively with RS and positively with MH. Research also suggests child abuse (CA) to be associated with poorer CS, lower RS, and poorer MH. Further, RS has been differentially associated with MH and CS in adult intimate relationships. However, no study has examined these associations simultaneously. The current study aimed to (1) assess these associations in IPV-exposed women and (2) assess differences between those with and without a history of CA. Data (n = 412; Mage = 36.77, SD = 12.54) come from a larger data collection project (N = 676). I hypothesized that: (1) higher CC and RS would be associated with lower severity of MH symptoms; (2) higher SD/PW and lower RS would be associated with higher severity of MH symptoms; (3) women with a history of CA will report less CC, lower RS, and higher severity of MH symptoms; and (4) women with a history of CA will report more SD/PW, lower RS, and higher severity of MH symptoms.

Prokofiev's Piano Sonata No. 4 in C Minor, Op. 29 (1917): A Performance Guide based on Interpretations by György Sándor and Boris Berman (open access)

Prokofiev's Piano Sonata No. 4 in C Minor, Op. 29 (1917): A Performance Guide based on Interpretations by György Sándor and Boris Berman

One of the famous Russian composers and a pianist himself, Sergei Prokofiev (1891–1953) composed a vast quantity of piano music. His nine piano sonatas represent well how he projected his musical individuality and the principles that he addressed in his autobiography: classical line, modern trend, toccata line, lyrical line, and grotesque line. However, even though Prokofiev's piano sonatas are considered one of the important collections in the piano repertoire, not all of them have gained popularity and only a few tend to be frequently performed by pianists today. For this reason, this dissertation focuses on one of his less-performed piano sonatas, No. 4 in C minor, Op. 29. The pianists György Sándor and Boris Berman were chosen as specialists in Prokofiev's piano works, and their performance editions and recordings are analyzed and compared as main references. This study provides analysis and a performance guide to this piano sonata. This guide discusses pedaling, fingering, phrasing, touch, voicing, tempo suggestion, articulation, hand distribution, and expression.

Politics and the Piano during the Great Proletarian Cultural Revolution in China: An Analysis of Three Piano Works, "Music at Sunset" (1975), "Hundreds of Birds Paying Homage to the Phoenix" (1973), and "Liuyang River" (1972)

As a political disturbance and social movement, the Cultural Revolution hugely impacted the development of Chinese piano art. The piano went through many stages throughout this ten-year period. This dissertation examines the suppression and later expansion of piano music in China during the Cultural Revolution, along with the historical motivations and forces that shaped each stage of its development. The study is supported by historical documents and relevant literature. This dissertation includes an analysis of the roles that piano music played during this era and the piano's relationship with the Cultural Revolution's modernizing goals. The analysis focuses on the musical characteristics of three piano pieces from this period and explores the instrument's historical importance, to better understand how Chinese piano music maintained a careful balance between its value as a tool for socio-political propaganda and its transformation under the burden of political pressure and creative limitations. Additionally, this dissertation examines playing techniques in these works that define a distinctly Chinese piano style that is enormously popular today. To complement the dissertation, these piano pieces were performed during the dissertation recital.

Examining the Relationship of Critical Thinking Educational Efforts on Student Grade Point Average and Program Retention (open access)

Examining the Relationship of Critical Thinking Educational Efforts on Student Grade Point Average and Program Retention

Demand for the skill of critical thinking is extensive in both higher education and in the workforce. The purpose of the current research is to examine the relationship between critical thinking educational efforts (e.g., programs incorporating high impact practices) and higher education student outcomes. For this study, student outcomes were defined as cumulative grade point average and student program retention. The study used existing data which were obtained from a large public research university in the southwest United States. The study found that higher critical thinking was significantly associated with higher overall GPA, and this relationship was stronger in males as compared to females. However, students' critical thinking was not significantly related to program retention. Findings from this study appear to confirm previous studies indicating a positive relationship between students' ability to think critically and GPA. The study also suggests that elements promoting critical thinking can be successfully embedded into undergraduate curricula through various means, including the use of high impact practices.

The Question Concerning Endocrinology: Judith Butler's Gender Theory and Transgender Hormone Therapy (open access)

The Question Concerning Endocrinology: Judith Butler's Gender Theory and Transgender Hormone Therapy

For such a vexing topic as gender identity, this dissertation asks a rather straightforward question: If gender identity is—as Judith Butler has asserted—socially constructed and discursively mediated, then why does transgender hormone therapy (THT) work? This is the question concerning endocrinology that I ask Butler, and their answer is, if requiring of delicate assessment and interpretation, clear: it doesn't. Butler's work reveals an admonishing view that the efficacity of THT is due to placebo effect, in turn brought on by the bewitchment of the trans* who seeks medical transition. In a logic similar to sin and salvation, if only the trans* had not believed in gender dysphoria, then there would be no (putative) efficacity to THT whatsoever. With our answer, we begin a perilous adventure of discovering just why such a preeminent gender theorist (and trans* themselves) with no experience of gender dysphoria, and no desire to medically transition, would say this. We examine Butler's gender theory, their concept of desire, their views on the self, on transsexuality, their rarely discussed philosophies of science and nature, and their dearth of citations of transsexual voices. Due to this lack, I lend my own, relying upon my experience with gender dysphoria, THT, …

Air Breathing Fish: Development of Air Breathing in Bristlenose Plecos (Ancistrus cirrhosus)

The bristlenose pleco (Ancistrus cirrhosus) is a species of armored catfish in the Loricariidae family that breathes air facultatively when the aquatic environment becomes hypoxic. The bristlenose pleco uses its highly vascularized stomach as an air breathing organ. The two main goals of this developmental study were to determine the size of onset of air breathing and to determine the frequency of air breathing behavior in bristlenose plecos from juveniles to adults. Developing juveniles reach functional maturity within four to six months of hatching and grow to an adult size of eight to ten cm in length. To examine the developmental timing for the onset of air breathing, we tested different sized juveniles beginning at one cm up until 8 cm in length. The developmental timing for the onset of air breathing was measured by exposing each fish to a slowly decreasing aquatic oxygen content from 100% air saturation down to 8% air saturation. Fish were first able to breathe air at just over 2 cm and 1 gram in mass. There was a weak negative correlation between fish length and % air saturation at which air breathing began. When exposed to 15% air saturation, frequency of air breathing was …

NCAA College Coaches' Attitudes and Perceptions of LGBQ+ Student-Athletes: A Qualitative Analysis (open access)

NCAA College Coaches' Attitudes and Perceptions of LGBQ+ Student-Athletes: A Qualitative Analysis

Due to their influential roles in the lives of their players, understanding coaches' attitudes and perceptions toward LGBQ+ student-athletes is essential for assessing how safe collegiate sport environments are for LGBQ+ athletes. However, the research in this area has been limited. The present study aims to address this gap by investigating coaches' perceptions of LGBQ+ athletes to inform policy and education for promoting inclusive sport environments for these athletes. Participants were 1,533 collegiate coaches (Mage = 39.65 years; women = 41.3%; White = 83.7%; non-Hispanic = 86.4%; heterosexual = 74.9%) drawn from all three NCAA Divisions. In an open-ended, text response question, coaches were asked to identify the extent to which they would support and accept athletes on their teams being open about their sexual orientation and/or gender identity, and to describe the reasoning for their beliefs. Through reflexive thematic analysis, six higher order themes capturing coaches' rationales were identified: (a) levels of acceptance, (b) i coach, therefore i am…, (c) supportive environments are essential, (d) as a queer coach…, (e) limiting queerness, and (f) sexual orientation does not provide a competitive advantage. Analyses illuminate avenues for LGBQ+ athlete inclusion policies and training for coaches.

Shakespeare and Early Modern Trauma

Shakespeare references humoral medical theory and social definitions of gender throughout much of his work. His references to medical practices like purging, the siphoning of excessive emotional fluids to bring the body into balance, are more than allusions to medical theories. Shakespeare's works unveil and challenge early modern approaches to emotional experience, most particularly when it comes to traumatic experiences that overwhelm comprehension. In Titus Andronicus (1592), The Rape of Lucrece (1593), Hamlet (1603), King Lear (1608), and Macbeth (1606), Shakespeare invokes humoral theory to articulate the early modern traumatic experience and to criticize the efficacy of purging in representations of trauma. For Shakespeare, the siphoning of destabilized emotions, through metaphorical and rhetorical practices, has dangerous consequences for bodies coded as feminine.

Relations among Involuntary Stress Responses, Social Support, and Cortisol Output during Acute Social Stress among Adolescent Girls (open access)

Relations among Involuntary Stress Responses, Social Support, and Cortisol Output during Acute Social Stress among Adolescent Girls

This investigation utilized data from a previous laboratory-based study to examine the interactive contributions of trait involuntary stress responses (ISRs, e.g., rumination) and perceived familial social support (SS) on the hypothalamic-pituitary-adrenal axis (HPA; as indexed via salivary cortisol) response to acute stress in a sample of 128 adolescent girls ages 12 to 16. Participants completed a modified Trier Social Stress Test (TSST), and physiologic stress response was indexed via six salivary cortisol samples. Dimensions of ISRs and familial social support were entered into regression models to predict total cortisol circulation defined by area under the curve with respect to ground (AUCG; Pruessner et al., 2003) following the TSST. Neither ISRs or SS were associated with cortisol AUCG, nor was there an interactive effect of SS on relationships between ISRs and AUCG. Implications of present results and methodological recommendations for future investigations are discussed. This may be the first investigation to consider the interactive effects of ISRs and social support on adolescent girls' HPA responses. Greater understanding of these factors in this understudied demographic will improve translational science as well as inform risk assessment and intervention development.

Unveiling Hidden Problems: A Two-Stage Machine Learning Approach to Predict Financial Misstatement Using the Existence of Internal Control Material Weaknesses

Prior research has provided evidence that the disclosure of internal controls material weaknesses (ICMWs) is a powerful input attribute in misstatement prediction. However, the disclosure of ICMWs is imperfect in capturing internal control quality because many firms with control problems fail to disclose ICMWs on a timely basis. The purpose of this study is to examine whether the existence of ICMWs, including both the disclosed and the undisclosed ICMWs, improves misstatement prediction. I develop a two-stage machine learning model for misstatement prediction with the predicted existence of ICMWs as the intermediate concept; my model that outperforms the model with the ICMW disclosures. I also find that the model incorporating both the predicted existence and the disclosure of ICMWs outperforms those with only the disclosure or the predicted existence of ICMWs. These results hold across different input attributes, machine learning methods, and prediction periods, and training-test samples splitting methods. Finally, this study shows that the two-stage models outperform the one-stage models in predictions related to financial reporting quality.

Views from the Beach: Spectator Positions and the American International Pictures Beach Party Films

The American International Pictures (AIP) Beach Party Films were a major American cultural phenomenon in the early 1960s and continue to play a significant role in the American cultural imagination. The AIP Beach Party Films, despite their popularity and influence, have been largely ignored by academia and a thorough academic examination has yet to be written. This thesis attempts to change such an academic precedent. At first glance, the Beach Party Films are frivolous and chaotic (perhaps explaining the lack of academic inquiry). However, upon closer examination, the Beach Party Films are laden with cultural artifacts, insights into American culture of the late 1950s and early 1960s and provide a view into the tenuous relationship between 1960s American dominant culture and developing countercultures. Further, the Beach Party Films reveal a 1960s cultural lull; a culture that was caught between the dominant culture of 1950s America and the explosive cultural changes of the late 1960s that had yet to occur. By closely looking at the AIP Beach Party Films, and doing so through the lens of various cultural critics, there can be described potential cultural perspectives from early 1960s America.

A Performance Guide to a Forgotten Piece by Carl Czerny: "Fantaisie sur des melodies de Beethoven," Op. 752 (1844)

Carl Czerny (1791-1857) was an Austrian piano teacher, composer, pianist, historian, and theorist, who made many contributions to the musical world. He wrote many pieces of music over the course of his life, the most familiar to us being his exercises. His other types of work are less known and studied nowadays for various reasons. Yet it cannot be denied that Czerny was a very important figure who should not be allowed to fade away. We must delve deeper into his life and uncover more of his pieces, to reveal aspects of his work that are unknown for us. This study concentrates on the forgotten piece Fantaisie sur des mélodies de Beethoven, Op. 752. This is one of the pieces that I included in a World Premiere release recording issued by Toccata Classics. The intent of the program for the recording was to change the traditional concept of Czerny's work and show that his compositions are worth adding to today's recital repertoire. The program included five forgotten pieces by Czerny, of which Op. 752 was the most complicated and virtuosic. The purpose of this study is to analyze the piece and illustrate practicing methods or solutions for the technical challenges …
