Characterization Of The Hippocampal Acetylcholine System In A Rodent Model Of Fetal Alcohol Syndrome, Amy Elizabeth Perkins
Characterization Of The Hippocampal Acetylcholine System In A Rodent Model Of Fetal Alcohol Syndrome, Amy Elizabeth Perkins
Theses and Dissertations
Fetal alcohol spectrum disorders (FASD) are a major public health concern, as it is estimated that 2-5% of children are exposed to alcohol at some point during prenatal development. FASD have been shown to cause damage to multiple brain regions, but research shows that the hippocampus is especially sensitive to alcohol exposure. This damage to the hippocampus explains, in part, deficits in learning and memory that are hallmark symptoms of FASD. The acetylcholine neurotransmitter system plays a major role in learning and memory, and the hippocampus is one of its main targets. This experiment used a rodent model of Fetal …
Project Shine: A Family-Based Intervention For Improving Physical Activity, Sedentary Behavior, And Diet In African American Adolescents, Sara M. St. George
Project Shine: A Family-Based Intervention For Improving Physical Activity, Sedentary Behavior, And Diet In African American Adolescents, Sara M. St. George
Theses and Dissertations
This study examined the effects of a family-based intervention for improving moderate-to-vigorous physical activity (MVPA), sedentary behavior (SB), and fruit and vegetable (F&V) intake in African American adolescents. The intervention (Project SHINE: Supporting Health Interactively through Nutrition and Exercise) integrated Social Cognitive (SCT), Self Determination (SDT), and Family Systems Theories (FST) to improve healthy physical activity and dietary behaviors. Behavioral strategies from SCT (i.e., self-monitoring, goal-setting, self-regulatory skill-building), elements involved in facilitating intrinsic motivation for health behavior change from SDT (i.e., autonomy, competence, belongingness), and positive parenting practices from FST for integrating parent and peer systems (e.g., parental monitoring, parent-adolescent …
Testing Bidirectional Contextual Effects Of Adolescent Risk Factors On Young Adulthood Outcomes: A Life Course Perspective To Gangs, Andrea E. Lamont
Testing Bidirectional Contextual Effects Of Adolescent Risk Factors On Young Adulthood Outcomes: A Life Course Perspective To Gangs, Andrea E. Lamont
Theses and Dissertations
Leading theories in developmental science emphasize the role of the individual as an active agent in shaping her or his environment. Yet, most empirical work has focused on unidirectional models, ultimately treating the individual as a passive recipient of environmental risk. Part of this gap between theory and analysis is methodological in nature – i.e., classical statistical methods typically do not allow for the modeling of bidirectional influences or complex longitudinal relations. Recent advancements in longitudinal methodologies, however, expand our ability to answer more nuanced developmental questions. In this dissertation, I demonstrate how advanced longitudinal methods could be used to …
