The Potential Role Of Trauma-Informed Positive Education In The Secondary Mathematics Classroom In Disrupting The Preschool-To-Prison Pipeline, Jessica Michele Doering

Theses and Dissertations--Education Sciences

This mixed-methods study considered the potential for trauma-informed mathematics education to disrupt the preschool-to-prison (or school-to-prison) pipeline. Phenomenological qualitative interviews were conducted in conjunction with the use of the Attitudes Related to Trauma-Informed Care (ARTIC; Baker et al., 2016) scale to determine teacher perceptions of trauma-informed care practices, their thoughts regarding challenging classroom behaviors and the connection of these behaviors with trauma and the pipeline, and their ideas about how much of an impact teachers can have on students who present with challenging behaviors that might be symptoms of trauma or that might be an indicator of future incarceration. This …

Three Essays On The High-Speed Rail Network In China, Shiyu Cheng

Theses and Dissertations--Economics

My dissertation consists of three essays that study the economic consequences of China’s high-speed rail (HSR) expansion.

In the first essay, I use the college admission cutoff scores to reveal students’ college preferences under the enrollment quota. By exploiting the quasi-experimental variation in whether or not college cities are connected by the HSR network, I document a two-point increase in the cutoff scores following a HSR station opening in the college city using difference-in-difference (DD) approach. Colleges in the megacities experience a larger increase in cutoff scores after the station opening. These findings suggest that the HSR network stimulates “brain …

Center for Applied Energy Research Faculty and Staff Publications

Despite the many advantages of microalgae, the feasibility of large-scale cultivation requires significant amounts of carbon dioxide (CO2) to enable high growth rates. A synergistic union typically proposed for the supply of CO2 is the coupling of algal cultivation with emissions from power plants. This study investigates the sustainability of a novel microalgae platform coupled with coal-based flue gas. The proposed system consists of a novel photobioreactor (PBR) for the production of biomass followed by a two-stage dewatering process. A systems model, which quantifies the CO2 and energy consumption of the proposed system, was developed, and the minimum biomass selling …

Dietary Assessments And Their Association With Psychological Factors, Inflammation, And Cardiovascular Health Outcomes, Junghee Kang

Theses and Dissertations--Nursing

Cardiovascular diseases (CVDs), a group of disorders of the heart and blood vessels, are the leading cause of death worldwide, causing one-third of deaths each year. Diet is one of the most important behavioral risk factors for CVD. The effects of behavioral risk factors, such as diet, may lead to increased blood pressure, increased blood glucose, raised blood lipids, and overweight and obesity. Inflammation contributes to the development of CVD and can be influenced by diet. Dietary assessment indices can measure diet quality from an individual's dietary intake by scoring food and nutrient intakes. However, the mediation effects of diet …

Biology Faculty Publications

Plants are often exposed to abiotic stresses such as drought, salinity, heat, cold, and heavy metals that induce complex responses, which result in reduced growth as well as crop yield. Phytohormones are well known for their regulatory role in plant growth and development, and they serve as important chemical messengers, allowing plants to function during exposure to various stresses. Seed priming is a physiological technique involving seed hydration and drying to improve metabolic processes prior to germination, thereby increasing the percentage and rate of germination and improving seedling growth and crop yield under normal and various biotic and abiotic stresses. …

I Need To See Me On Tv: Parasocial Affirmations Of Sexual And Gender Identity Development Of Lgbtq+ Mass Media Consumers, Donald I. Lowe

Theses and Dissertations--Communication

This dissertation presents a new cycle model of media usage by LGBTQ+ community members in the United States that reveals a purpose previously unnamed and undefined. While parasocial contact, parasocial interaction, and parasocial relationships have been present in the academic literature for quite some time (as early as 1956 when Horton and Wohl first wrote of the phenomenon), use of media to parasocially affirm one’s LGBTQ+ status is unique to this study. This study used qualitative methods to examine a specific mass media audience, LGBTQ+ individuals, and asked them, in one-on-one interviews, how they utilize mass media to assist with …

Does Bullying Victimization In Middle Childhood Influence Adolescent Risk Behaviors: Differences Across Racial/Ethnic Groups?, Shawndaya Sabrina Thrasher

Theses and Dissertations--Social Work

Bullying is a public health problem that negatively affects millions of children annually and can have serious, long-lasting effects on victims. Emergent research concludes a higher prevalence of bullying occurs in earlier school years, especially among racial/ethnic minorities. Evidence also suggests that risk behaviors associated with bully victimization may vary by racial/ethnic profile, leading to disproportionate chances of adverse psychosocial and health-related behaviors. Therefore, racial/ethnic minority youth may be more likely to cope with being bullied through risk behaviors (e.g., coping by fighting).

Current investigations of racial/ethnic differences in the bullied-risk relationship examine few risk behaviors (i.e., academic performance and …

Impact Of Mineral Supplementation On Intake Behavior And Blood Flow In Growing Beef Cattle Exposed To Fescue-Derived Alkaloids, Hannah Marie Herzing

Theses and Dissertations--Animal and Food Sciences

Consumption of endophyte-infected tall fescue by cattle has repeatedly been shown to negatively impact dry matter intake (DMI), growth rate, and circulating prolactin concentrations. The objective of the current study was to determine if a mineral supplementation would mitigate the negative effects of fescue-derived alkaloid consumption on feed intake, circulating prolactin, and the vascular system. Twelve Angus crossbred steers were used in a triplicated Latin square design consisting of three 28 d experimental periods. Treatments consisted of three top-dressed mineral supplements (142 g/head/d): a non-medicated control (CON), commercially available Fescue EMT® Mineral Defense (EMT), and a test prototype (EMT 2). …

The Effects Of Form Of Selenium On The Bovine Corpus Luteum, Uterine Endometrium, And Development Of The Conceptus, Benjamin Ryne Crites

Theses and Dissertations--Animal and Food Sciences

Widespread regions of the southeast United States have soils deficient in selenium (Se), necessitating Se supplementation to cattle grazing in these areas. Adequate dietary Se is required for optimal immune function, growth, and fertility. In forages, Se is predominantly found in the organic form (OSe), which is known to increase bioavailability. However, the inorganic form (ISe) is typically found in commercial mineral mixes. We previously reported that supplementation with an isomolar 1:1 mix (MIX) of ISe (sodium selenite, Prince Se Concentrate; Prince Agri Products, Inc., Quincy, IL) and OSe (SEL-PLEX, Alltech Inc., Nicholasville, KY) increases early luteal phase concentrations of …

Monocyte Abundance And White Blood Cell Expression Of Prolactin And Nf-Kb Pathway Genes In Beef Steers Are Altered By Grazing Toxic Endophyte-Infected Tall Fescue And Lipopolysaccharide Challenge, Cecilia Winfrey

Theses and Dissertations--Animal and Food Sciences

Experiment 1 tested the hypothesis that ad libitum consumption of a 1:1 blend (MIX) of sodium selenite (ISe) and SELPLEX vs solely ISe as selenium (Se) supplements (27 ppm) in a vitamin-mineral mix (V-M) by steers subjected to summer-long grazing of toxic endophyte-infected tall fescue (TE) would ameliorate the negative effects of TE by positively affecting the expression pattern of prolactin (PRL) and NF-kB pathway genes by circulating leukocytes (WBC). Experiment 2 tested the hypothesis that the MIX form of supplemental Se also would ameliorate the negative effects of in vitro blood lipopolysaccharide challenge (LPS) on WBC gene expression. The …

Theses and Dissertations--Animal and Food Sciences

Anecdotal evidence of beneficial behavioral and health effects of cannabidiol (CBD) use in companion animals has amplified the need to elucidate safety and potential impacts of CBD use. The purpose of this investigation was to determine the impact of industrial hemp-derived CBD administration on canine health and well-being. We hypothesized that CBD would produce beneficial effects on canine behavior without negatively impacting animal health. Dog treats were formulated to include CBD and shown to be palatable across a range of CBD inclusion levels. Dogs were supplemented with CBD treats and subjected to a noise-induced fear response test to assess potential …

Death, Discipline, And The Dead: Biopolitical Rhetoric In Early Modern English Texts, Leslie Raybuck Malland

Theses and Dissertations--English

Death, Discipline, and the Dead: Biopolitical Rhetoric in Early Modern English Texts locates allusions to the biopolitical culture of Early Modern England within popular English texts. Through my examination of the period’s fascination with death—public executions, newly-authorized anatomies—and the ways in which death, as well as the treatment of the dead, was authorized by and supported the ideological aims of the state, my research identifies how those themes carry over into the most popular works of the day, reviewing instances of both verbal and nonverbal rhetoric across genres to find allusions to biopower — or, state control of the biological. …

Development And Clinical Validation Of Knowledge-Based Planning Models For Stereotactic Body Radiotherapy Of Early-Stage Non-Small-Cell Lung Cancer Patients, Justin David Visak

Theses and Dissertations--Radiation Medicine

Lung stereotactic body radiotherapy (SBRT) is a viable alternative to surgical intervention for the treatment of early-stage non-small-cell lung cancer (NSCLC) patients. This therapy achieves strong local control rates by delivering ultra-high, conformal radioablative doses in typically one to five fractions. Historically, lung SBRT plans are manually generated using 3D conformal radiation therapy, dynamic conformal arcs (DCA), intensity-modulated radiation therapy, and more recently via volumetric modulated arc therapy (VMAT) on a C-arm linear accelerator (linac). Manually planned VMAT is an advanced technique to deliver high-quality lung SBRT due to its dosimetric capabilities and utilization of flattening-filter free beams to improve …

Residual Spatial Autocorrelation In Macroecological And Biogeographical Modeling: A Review, Guetchine Gaspard

Theses and Dissertations--Geography

Macroecological and biogeographical modelers have predicted the distribution of species across space relying on the relationship between biotic processes and environmental variables. Such a method employs data associated, for instance, with species abundance or presence/absence, climate, geomorphology, and soils. Statistical analyses found in previous studies have highlighted the importance of accounting for the effects of spatial autocorrelation (SAC), which indicates a level of dependence between pairs of nearby observations. A consensus has existed that residual spatial autocorrelation (rSAC) can substantially impact modeling processes and inferences. However, more emphasis should be put on identifying the sources of rSAC and the degree …

Effects Of Season And Nutrition On Insulinemic Responses In Insulin Dysregulated Horses, Erica Lyn Macon

Theses and Dissertations--Veterinary Science

Insulin dysregulation (ID) is the main risk factor for the development of hyperinsulinemia-associated laminitis (HAL). ID in the equid has been extensively researched; however, recommendations for diagnosing and managing ID horses have originated from work completed in other models, such as the ID pony and healthy horse. Therefore, our overall objective was to improve current diagnostic tools and nutritional management strategies by investigating the effect of season, the fed and fasted state on the oral sugar test (OST) and dietary nutrient content on insulinemic responses in the ID horse. To address this, four main objectives with three specific aims were …
