Some eyespots are thought to deflect attack away from the vulnerable body, yet there is limited empirical evidence for this function and its adaptive advantage. Here, we demonstrate the conspicuous ventral hindwing eyespots found on Bicyclus anynana butterflies protect against invertebrate predators, specifically praying mantids. Wet season (WS) butterflies with...
Past research on Head Start has focused on child outcomes, yet Head Start services also target the behaviors of parents. Using data from the Fragile Families and Child Well-being Study (FFCW), the current study examined the effect of Head Start on mother (n = 3,575) and father (n = 1,812)...
While the use of powered mobility devices for young children with mobility challenges has taken off in recent years following evidence that the use of powered mobility at a young age augments other traditional mobility skill interventions, the research is still limited and focuses on physical impacts more. Recently, the...
The purpose of this study was to test the effects of guided imagery on cognition, depression, anxiety, quality of life, behavior symptoms, and perceptions of self and others in people with dementia. A nonequivalent control group quasi-experimental design was used to compare an attention control group to the intervention group....
A hybrid Quasi-diffusion/Monte Carlo Method for solving multigroup criticality problems in slab geometry was investigated. Analog Monte Carlo was used to calculate functionals (Eddington Factors) that were then used in solution of the quasi-diffusion equations. The hybrid method was shown to accurately and precisely predict the k-eigenvalue and fission source...
Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...
School interventions have typically focused on academic and psychological outcomes for children, but can children carry positive effects home from school to influence their parents and home environments? Developmental research typically focuses on how parents influence development in their children, but this study flips this lens to ask whether children...
This work explores the synthesis and characterization of the metastable alloys Sn1-xCaxCh (Ch= S, Se) and nitride compounds Zn-W-Mo-N, which have recently been predicted by theorists. Single phase thin films of Sn1-xCaxS are prepared by pulsed laser deposition and radio-frequency magnetron sputtering and of Sn1-xCaxSe are prepared by pulsed laser...
Crystal-rich (40-50 vol.%) intermediate lava has been the primary eruptive product of several recent hazardous eruptions: Mt. Pinatubo, Philippines (1991), Soufriere Hills, Montserrat (1995-present), and Unzen, Japan (1990-1995). Despite this association with such devastating eruptions, the formation, timing, and evacuation of such magma is not well understood: do such eruptions...
Learning about periodic and oscillatory systems is a huge step in an undergraduate's
comprehensive understanding of physics and complex systems such as solids. However,
understanding how specific changes to such a system affect aspects of the entire system can
be difficult. The goal of this study is to create a...
