Latino Family Involvement: An Exploratory Study of Latina Mother-Daughter Relationships and their Effects on Educational Attainment and Resiliency

Latino family involvement is an important issue in the field of education. Effective strategies to promote family involvement in the Latino community are vital for the educational attainment of Latino students and emotional wellbeing of Latino families. This study used focus groups, in-depth interviews, and observations to examine Latino family involvement and the relationships and communication patterns between Latina mothers and daughters. The Latina mother-daughter relationship was studied in an effort to gain a better understanding of how this relationship affects a Latina daughter's educational attainment and sense of resiliency. Results indicated that a positive relationship between a Latina mother and daughter can increase a Latina daughter's level of educational attainment and sense of resiliency. Additionally, a Latina daughter's level of self-motivation can affect her level of educational attainment as well. Cultural narratives were found to be a common type of communication pattern used between Latina mothers and daughters. They were used to teach cultural values, life lessons, and experiential learning. By improving family involvement efforts within the Latino culture, Latino students will likely see drastic improvements in their overall levels of educational attainment and emotional wellbeing in schools. Implications for Latino students and families, schools that work with Latino families, and educational policy are also discussed.

Acute Synaptic Activity Causes Differential miRNA Expression in The Drosophila melanogaster Larval Central Nervous System

The primary goal of this thesis was to determine if spaced synaptic stimulation induced the differential expression of microRNAs (miRNAs) in the Drosophila melanogaster central nervous system (CNS). Prior to attaining this goal, we needed to identify and validate a spaced stimulation paradigm that could induce the formation of new synaptic growth at a model synapse, the larval neuromuscular junction (NMJ). Both Channelrhodopsin- and high potassium-based stimulation paradigms adapted from (Ataman, et al. 2008) were tested. Once validation of these paradigms was complete, we sought to characterize the miRNA expression profile of the larval CNS by miRNA array. Following attainment of these data, we used quantitative real-time PCR (RT-qPCR) to determine if acute synaptic stimulation caused the differential expression of neuronal miRNAs. We found that upon high potassium spaced training in a wild type (Canton S) genotype, 5 miRNAs showed significant differential expression when normalized to a validated reference gene, the U1 snRNA. Moreover, absolute quantification of our RT-qPCR study implicated one miRNA: miR-958 as being significantly regulated by activity. Investigation into potential targets for miR-958 revealed it to be a potential regular of Dlar, a protein tyrosine phosphatase implicated in synapse development. This investigation provides the foundation to directly test our underlying hypothesis that, following spaced training, differential expression of miRNAs alters the translation of proteins required to induce and maintain these structural changes at the synapse.

The Identification of Best Management Practices in a Materials Recovery Facility to Increase Solid Waste Diversion in the Department of Defense (DoD) Installations along the Front Range of Colorado to Satisfy the DoD Solid Waste Diversion Goal of 40 Percent

The five installations operated by the Department of Defense (DoD) in the Front Range region of Colorado do not meet the DoD non-hazardous solid waste diversion goal of 40 percent, further impacting landfills and generating greenhouse gases. This applied capstone project identifies and evaluates best management practices of a Materials Recovery Facility (MRF), qualitatively and quantitatively, to increase solid waste diversion at a DoD MRF. An environmental benefits model quantified the externalities of increasing solid waste diversion at the installations. By implementing best management practices at a MRF, the DoD would divert an additional 1,400 tons of solid waste per year, resulting in the equivalent of 1,502,567 gallons of gasoline being saved, among many benefits presented in this capstone.
