The Mysterious Mu Wave: The Effects Of Tdcs On Visuomotor Integration And Processing, Jessica Lynn Van Bree

Theses and Dissertations

Visuomotor integration is the coordination of neuronal activity between the motor- and vision-related parts of the brain that influence behavior and perception, resulting in a motor reaction (Shin et al. 2016). Previous studies have demonstrated that longitudinal training of oculomotor, visual, attentional, and motor skills produce significant improvements of visuomotor integration and control in healthy subjects. Within healthy populations, transcranial direct current stimulation (tDCS) has been found to facilitate visuomotor learning, motion processing, and the coordination and accuracy of motor movement (Antal et al., 2004; Coffmann et al., 2014). As such, tDCS may be an appropriate addition to the rehabilitation …

Ccl2 Suppression In Lewis Lung Carcinoma Model Enhances Host Survival And Immune Response In The Tumor Microenvironment, Nivedita Biswas

Theses and Dissertations

CCL2, a chemokine also referred to as monocyte chemoattractant protein 1 (MCP-1) and small inducible cytokine A, is chemotactic for monocytes. CCL2-induced recruitment of CCR2+Ly6C(hi) monocytes increases vascular permeability CCR2+ endothelium aiding the escape and migration of tumor cells. CCL2 is produced by cancers of varied immunogenicity and augments tumor proliferation and metastasis. Elevated CCL2 expression by tumor cells is linked to poor prognosis.We have previously shown that two bacterially derived superantigens, Staphylococcal enterotoxin G and I (SEG/SEI) stimulate large numbers of T cells in an antigen-independent fashion and promote enhanced survival in the poorly immunogenic B16-F10 melanoma model. Conversely, …

Self-Identification From The Professional And Social Perspectives Of Flight, Carly Lane Crockett

Theses and Dissertations

The development of one’s identity is connected to the level of effort willing to be committed to goal achievement. Per Velleman (2006), what someone cares about, determines what they must do for survival (p.336). While identity has been dissected, the applicability of connection for social and professional ties within aviation has not been thoroughly processed. General aviation flying and that of airline pilots has been compared regarding skill and safety association, but not in identity construction. A population of airline pilots was researched, that may or may not have been actively participating GA, with attempt to establish factor recognition of …

Religion-Justified Childhood Maltreatment And Adult Psychological Maladjustment, Hannah Doctor

Theses and Dissertations

The perpetrator of religion justified child abuse relies on spiritual beliefs (religious texts, context, or authority) to justify acts of maltreatment. This form of abuse can be manifested in many different contexts including infamous scandals of sexual abuse committed by catholic priests and the physical/sexual/emotional maltreatment occurring at Native American or other boarding schools for troubled youth. Parents and caretakers often claim "to spare the rod is to spoil the child”. Previous research has suggested that maladjustment outcomes after traumatic events are less severe among victims with strong religious beliefs. This study hypothesized that religious justified abuse would be associated …

Soil Bacteria Composition In Conservation Reserve Program Grasslands Of The Great Plains, Lydia M. Kantonen

Theses and Dissertations

The Conservation Reserve Program (CRP) is a grassland restoration program that allows landowners to remove degraded land from crop production, seed it with a perennial seed mixture, and leave it fallow for the remainder of the contract, which usually ranges from 10-15 years. While some ecosystem functions quickly improve upon CRP enrollment, soil organic carbon is slow to return to pre-agricultural levels. One explanation is that particulate organic matter left by litter takes several years to degrade even with a full bacteria community. Alternatively, it is possible that different chemical components of organic matter require different bacteria communities for full …
