Understanding Object Motion Encoding In The Mammalian Retina., Victor Julian Depiero

Electronic Theses and Dissertations

Phototransduction, transmission of visual information down the optic nerve incurs delays on the order of 50 – 100ms. This implies that the neuronal representation of a moving object should lag behind the object’s actual position. However, studies have demonstrated that the visual system compensates for neuronal delays using a predictive mechanism called phase advancing, which shifts the population response toward the leading edge of a moving object’s retinal image. To understand how this compensation is achieved in the retina, I investigated cellular and synaptic mechanisms that drive phase advancing. I used three approaches, each testing phase advancing at a …

The Role Of Prenatal Empowerment In Predicting Parent And Infant Outcomes Among Working Women, Yao Yao

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The current study examined the relationship between women’s prenatal empowerment and children’s social-emotional competence. A longitudinal study was conducted in Nebraska that included (N = 38) working women and their infants. Mothers’ prenatal empowerment and infants’ social-emotional competence, parental stress, parent-child relationship, and mothers’ knowledge of infant development were measured. Results from the current study did not support a direct association between mothers’ prenatal empowerment and infants’ social-emotional competence. However, mothers’ prenatal empowerment and infant’s social-emotional competence were both significantly related to parental stress. These findings indicate that prenatal empowerment may have an indirect relationship with infants’ social-emotional development. …

A Longitudinal Examination Of Bedtime Routines And Sleep In Toddlers, Amanda Prokasky

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Ample research has examined the impacts of sufficient and high-quality sleep on children’s health, development, and well-being (Chen, Beydoun, & Wang, 2008; Gregory & Sadeh, 2012; Touchette et al., 2009), yet less research has focused on the factors that contribute to sufficient and high-quality sleep in early childhood. The bedtime routine is one environmental influence on children’s sleep that has received little attention in the literature base and therefore is the focus of the current study.

A Mixed Methods Approach To Understanding The Juvenile Re-Entry Mentoring Process, Sara E. Moore

Student Work

Juvenile mentoring programs are an institution of informal social control that through programmatic design intends to mitigate delinquent behaviors with the development of strong quality social bonds. In these programs, mentees involved in the juvenile justice system are matched with older mentors to form social bonds as a method of encouraging prosocial behaviors. The Juvenile Reentry Mentoring Project (JRMP) is one such mentoring program matching juvenile mentees in the justice system with undergraduate mentors. Research is clear that the longer the match relationship, the stronger the relationship (Rhodes, 2007; Garringer et al., 2017). Yet, research is limited as to the …

Marine Science

Coastal inundation due to sea level rise (SLR) is projected to displace hundreds of millions of people worldwide over the next century, creating significant economic, humanitarian, and national-security challenges. However, the majority of previous efforts to characterize potential coastal impacts of climate change have focused primarily on long-term SLR with a static tide level, and have not comprehensively accounted for dynamic physical drivers such as tidal non-linearity, storms, short-term climate variability, erosion response and consequent flooding responses. Here we present a dynamic modeling approach that estimates climate-driven changes in flood-hazard exposure by integrating the effects of SLR, tides, waves, storms, …
