Sexual Abuse: A Multi-Faceted Problem, Marcus Venable

LSU Doctoral Dissertations

On average, US citizens have experienced approximately 400,000 sexual assaults per year, which results in enormous immediate and long-term consequences for individuals, as well as society in general.

In the U.S., the principal method of combatting this crime has been the creation of Sex Offender Registries used to notify the public of the identity and location of convicted sex offenders who may be living in proximity to their residence. In addition to the Registry, laws have been passed forbidding convicted sex offenders from residing within buffer zones around areas of high child concentration [schools/parks/etc.].

The efficacy and consequences of these …

Decoding Affective Information From Neuronal Populations In The Human Hippocampus, Alexander N. Lawriw

LSU Master's Theses

The hippocampus is understood to play a key role in the formation of episodic memories. Prominent theories suggest this is made possible through use of sparse encoding schemes, in which a small number of neurons encode each episodic event using a distinct pattern of neuronal activity. However, more recent computational models suggest that the hippocampus may also be capable of representing semantic structure, a notion previously thought to be exclusive to the neocortex. In our previous line of work, we trained multivariate classifiers to predict the semantic content, specifically affect, of computer-generated faces given spiking data taken from individual neurons …

The Association Between Problematic Drinking And Ends Use In College Students: The Role Of Alcohol Expectancies, Nina Glover

LSU Master's Theses

Electronic nicotine delivery system (ENDS) use and alcohol use are prevalent among young adults and college students. Recent data indicate that ENDS use is significantly associated with alcohol consumption and hazardous drinking behavior (e.g., binge drinking). Given the perceived benefits students report that are common across ENDS and alcohol use (e.g., tension reduction), it is important to examine the role these beliefs play in the co-use of alcohol and ENDS, as both behaviors are associated with risks. In the present study, we investigated the relationship among ENDS use, alcohol use, ENDS use motives, and alcohol expectancies in undergraduate college students …

Examining The Effects Of Differential Reinforcement And Time-Out On Unsafe Playground Behavior, Elizabeth K. Linton

LSU Master's Theses

The purpose of this study was to examine the effects of differential reinforcement (DRO) without extinction, and then the additive effects of time-out, on reducing unsafe playground behavior. The results of the DRO in isolation phase indicated that DRO alone was only consistently effective in reducing or eliminating unsafe behavior for one out of four participants. The other three participants moved on to the multielement comparison where the combination of DRO and time-out (DRO+TO) condition was added. The DRO+TO condition reduced and eliminated unsafe playground behavior for all participants who experienced the condition. Those participants engaged in higher levels of …
