Attachment Dynamics As A Precursor For Sexual Risk-Taking Behaviors In Emerging Adulthood (18-25 Years Old), Eimileanne Delaney

Graduate Research Theses & Dissertations

This study explored the relationship between attachment and sexual risk-taking behaviors in emerging adulthood. Understanding and identifying the variables that influence sexual risk behaviors are important to the design and implementation of therapeutic interventions and psychoeducation. It was hypothesized that there is a statistically significant relationship between attachment and increased levels of sexual risk-taking behaviors in emerging adults. To investigate the research hypothesis, this study used a quantitative correlational design to examine the relationship(s) between the variables. The participants completed three online questionnaires: a demographic questionnaire, the Sexual Risk Survey (SRS), and the Relationship Questionnaire (RQ). Results suggested that there …

Radiation Actions And Dimensions Of Radiation Safety Among U.S. Radiologic Technologists, Quentin T. Moore

Graduate Research Theses & Dissertations

Background: Radiation safety culture is a fundamental contributor to procedural justification, exam optimization, and dose-limiting practices in medical imaging. Multiple intrapersonal, interpersonal, institutional, community, and policy factors could influence the outcomes of radiation safety culture.

Purpose and Aims: The purpose of the study was to examine the determinants of radiation safety culture among U.S. radiologic technologists. The specific aims were to: 1) develop a survey instrument tailored to radiation actions and dimensions of radiation safety with a sequential use of multiple techniques; 2) examine determinants of radiation safety culture employing McLeroy’s socioecological model; 3) examine relationship between the determinants of …

Investigating The Behavioral Effects Of Juvenile Stress In The Prairie Vole Model, Marigny C. Normann

Graduate Research Theses & Dissertations

Early life stress during the juvenile period, such as emotional neglect, interpersonal difficulties, or other forms of non-violent maltreatment can have consequences into adulthood. Specifically, the negative effects include increased risk of psychiatric or physical illnesses, social deficits, and maladaptive behavioral responses to stress. Since these effects have far-reaching implications that can negatively alter later behavior and physiology, the present study assessed the effects of early life social stress on later social and affective behaviors in a social rodent species – the prairie vole. The prairie vole displays behavioral, cardiovascular, and neuroendocrine responses to social stress similar to those of …

The Role Of Medial Septum Cholinergic Function In Processing Self-Movement Cues To Maintain Spatial Orientation, Jenna Rae Osterlund

Graduate Research Theses & Dissertations

Wandering is the most life-threatening and commonly reported symptom of Alzheimer’s Disease (AD), a neurodegenerative disorder characterized by an inability to maintain spatial orientation. The often deadly consequences of wandering are projected to rise in the coming decades due to the advancing aged population. These upcoming challenges necessitate a more comprehensive understanding of the neurobiology of spatial orientation in order to evaluate novel therapeutic techniques for symptoms such as wandering. The inability to maintain spatial orientation in AD may be due to the pathological degeneration of the hippocampal cholinergic system. This neurological system is conserved across species for its function …

Hippocampal Cholinergic Function And Exploratory Behavior Throughout Development In A Genetic Mouse Model Of Alzheimer’S Disease, Ashley Andrea Blackwell

Graduate Research Theses & Dissertations

Dementia of the Alzheimer’s type is the most common form of dementia, affecting millions of people worldwide. Specific genetic mutations increase Alzheimer’s disease-related neuropathology and cognitive impairments. Deficits are observed in spatial orientation throughout the progression of Alzheimer’s disease, including wandering behavior or becoming lost in a familiar environment. Dementia of the Alzheimer’s type patients also exhibit disruptions in radial optic flow, which underlies self-movement cue processing. Currently, no treatments exist for Alzheimer’s disease. Genetic mouse models of Alzheimer’s disease have been developed to investigate the disease onset and progression and, further, to evaluate potential therapies and behavioral assessments. As …
