The Impact Of Gender-Biased Language In State Regulations Upon Judgments About Foster Children, Hannah R. J. Heinzel Oct 2016

The Impact Of Gender-Biased Language In State Regulations Upon Judgments About Foster Children, Hannah R. J. Heinzel

Theses and Dissertations

This study investigated the impact of gender-biased language in the wording of state regulations governing the treatment of foster children in Illinois. Participants were given excerpts of legal language written with either gender-biased or gender-inclusive language and then asked to judge a hypothetical situation involving a male or a female child. It was hypothesized that gender-biased language would have differential effects on interpretation of the language for boys versus girls; we also proposed a moderated mediation model that hypothesized activation of gendered constructs would mediate the interpretation of gendered language. According to the hypothesized model, participant sexism and attitudes towards …

Effect Of Cultural Intensity And Planting Density On Wood Properties Of Loblolly Pine (Pinus Taeda L.), Nasrin Aslezaeim

Theses and Dissertations

The effects of cultural intensity (operational and intensive) and planting densities (741, 1483, 2224, and 2965 ha-1) on modulus of elasticity (MOE), modulus of rupture (MOR) and specific gravity (SG) of small clear samples obtained from 15 and 16 year-old loblolly pine (Pinus taeda) from the Lower Coastal Plain and Piedmont region of the southeastern United State were examined. Planting density and distance from pith showed a significant (p < 0.0001) and strong main effect on stiffness (MOE) and strength (MOR) for the samples. Regardless of planting density, MOE, MOR and SG of samples increased significantly from pith toward bark. A significant culture × density interaction (p < 0.0001) was observed for the samples obtained from the Lower Coastal Plain. The project also determined the feasibility of measuring microfibril angle (MFA) on solid wood loblolly pine samples using scanning electron microscopy and transmission electron microscopy with the angle analyzed using image analysis. Measurements of MFA revealed minor differences (5⁰) between juvenile wood and mature wood.

Invasion Potential And Overwintering Biology Of The Redbay Ambrosia Beetle (Coleoptera: Curculionidae) In The United States, John Formby

Theses and Dissertations

Several native species of Lauraceae (e.g. sassafras) in the southeastern United States are being eradicated by laurel wilt disease. Laurel wilt is caused by a highly invasive and cryptic ambrosia beetle, Xyleborus glabratus, and its fungal symbiont. The symbiont pathogen is spread during colonization of native Lauraceae. Xyleborus glabratus and the pathogen are remarkably effective at colonizing and killing healthy populations of Lauraceae in a brief time period. Control methods have been unable to slow the spread of laurel wilt disease and X. glabratus populations have been spreading into northern latitudes. Presently, cold temperatures may be the only factor limiting …

Investigating Late Woodland-Period Aquatic Catchments Through Freshwater Mussel Assemblage Composition, Sarah K. Gilleland Aug 2016

Investigating Late Woodland-Period Aquatic Catchments Through Freshwater Mussel Assemblage Composition, Sarah K. Gilleland

Theses and Dissertations

During the Late Woodland Period in the American Southeast, the amount of space that any individual group could exploit began to shrink, due to the presence of other groups on the landscape. Resource expansion occurred to augment food supplies, resulting in increased exploitation of mussel beds. Because mussels can be extremely sensitive to the characteristics of the waterways they live in, the specific habitat requirements of these animals can be used to reconstruct the environments they were recovered from. In this thesis I use freshwater mussel assemblages to reconstruct hypothetical aquatic catchments and map them onto modern rivers in the …

The Effect Of Manganese (Mn) On Cell Proliferation And Migration In The Michigan Cancer Foundation-7 (Mcf-7) Human Breast Cancer Cell Line In Vitro, Justin Lloyd Wendel Aug 2016

The Effect Of Manganese (Mn) On Cell Proliferation And Migration In The Michigan Cancer Foundation-7 (Mcf-7) Human Breast Cancer Cell Line In Vitro, Justin Lloyd Wendel

Theses and Dissertations

Manganese (Mn) is a common environmental element necessary for mammalian physiological processes. However, dietary excess or deficiency can lead to detrimental health effects. Therefore, I investigated the effect Mn has on breast cancer progression in vitro. Utilizing MCF-7 breast cancer cells an MTT assay was performed to identify proliferative potential. After 5 days, results showed 100 nM manganese chloride (MnCl2) had a significant (p<0.01) increase in cell number over control. Using a scratch wound-healing assay, 100 nM MnCl2 was found to increase cellular motility as well as induce a possible change in morphology and cytoskeletal organization. Given Mn was shown to localize in the mitochondrial, we investigated Mn-induced ROS expression. 500 nM Mn significantly decreased (p<0.05) ROS levels. Collectively, I provide evidence that Mn may potentially drive less aggressive cancer cells towards a more invasive phenotype.

Emotion Dysregulation And Impulsivity As Moderators Of Treatment Response And Acceptability In Bulimia Nervosa, Mary E. Zander

Theses and Dissertations

There is great variability in personality among individuals with Bulimia Nervosa (BN; e.g., see Goldner, et al., 1999), such as on dimensions of impulsivity and emotion dysregulation. Individuals high on these traits appear to have different treatment needs compared to those who are low; however, little research has been conducted to evaluate the impact of these traits on treatment perception and success. There are several empirically supported treatments for BN, including Cognitive-Behavioral Therapy-Enhanced (CBT-E), Interpersonal Psychotherapy (IPT), and Integrative Cognitive-Affective Therapy (ICAT). Although each of these treatments may reduce eating disorder behaviors, they use different approaches to address or modify …
