"Shut Down And Closed Off": A Routine Activity Approach To Investigating The Relationship Between Covid-19 School Closures And Child Sexual Abuse Report Characteristics In Georgia, Spencer E. Riner

College of Graduate Studies: Theses & Dissertations

The COVID-19 pandemic of 2020 created a public health crisis that led to an unprecedented number of school closures. A major concern raised by child advocates, law enforcement, and social service providers was the possible increase in undetected child abuse and maltreatment. Undergirding this concern was the belief that this mitigation effort might place child abuse victims and offenders within proximity for extended periods of time. While this was a significant concern, it has rarely been analyzed empirically. To address this gap in the literature, this thesis investigates how school closures impacted the characteristics of child sexual abuse (CSA) reports …

Modeling The Effect Of Observational Social Learning On Parental Decision-Making For Childhood Vaccination And Diseases Spread Over Household Networks, Tamer Oraby, Andras Balogh Jan 2024

Modeling The Effect Of Observational Social Learning On Parental Decision-Making For Childhood Vaccination And Diseases Spread Over Household Networks, Tamer Oraby, Andras Balogh

School of Mathematical & Statistical Sciences Faculty Publications

In this paper, we introduce a novel model for parental decision-making about vaccinations against a childhood disease that spreads through a contact network. This model considers a bilayer network comprising two overlapping networks, which are either Erdős–Rényi (random) networks or Barabási–Albert networks. The model also employs a Bayesian aggregation rule for observational social learning on a social network. This new model encompasses other decision models, such as voting and DeGroot models, as special cases. Using our model, we demonstrate how certain levels of social learning about vaccination preferences can converge opinions, influencing vaccine uptake and ultimately disease spread. In addition, …
