Connecting Supplemental Nutrition Assistance Program (SNAP) recipients to resources at the farmers' market
Get PDFHonors Program, Department of Life SciencesThis project aims to examine the issue of poverty and food insecurities on individuals' nutrition in Corpus Christi, Texas- a city where 17% of the population falls below the poverty line (U.S. Census Bureau, n.d.). To address this, I have worked at the Grow Local Farmers' Market to increase access to fresh, nutritious food for SNAP recipients and provide education on its utilization.Acknowledgments: Grow Local South Texas Executive Director, Dr. Gilda Ramirez.

Assessing ecological connectivity of blacktip sharks (Carcharhinus limbatus) in the Gulf of Mexico using stable isotope analysis of multiple tissues
Get PDFEffective management of blacktip sharks relies on a comprehensive understanding of population distribution and stock structure. Previous stock separations and the implementation of regional quotas have proven successful in maintaining the sustainable harvest of blacktip sharks in both the Western North Atlantic and United States Gulf of Mexico (US GoM), in commercial and recreational fisheries. Within the US GoM, finer scale biological separation between blacktips in western and eastern regions has been supported through tagging, genetic, and diet data. This study provides additional evidence of unique ecological isotopic niche areas and δ15N and δ13C values for blacktip sharks from the western, central, and eastern US GoM across muscle and vertebral tissues that reflect different isotope turnover rates. Blacktip sharks from western and central regions exhibited isotope values and niches that were significantly smaller compared to eastern sharks, with enriched δ13C and depleted δ15N west of 88ºN. Ontogenetic shifts were noted for most regions and there was no crossover or overlap in average isotope values from early to recent life between regions. These spatiotemporal patterns suggest that in the year following birth and prior to the time of capture, blacktip sharks on the central and western shelves have separated ecologically from blacktips on the eastern US GoM Florida shelf
Determining source apportionment of Din and Don in a Gulf of Mexico watershed and airshed
Get PDFA dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Coastal and Marine Systems Science.Dissolved organic nitrogen (DON) profiles and contributing sources are poorly characterized in estuarine systems despite studies showing it constitutes a significant portion of the total nitrogen pool and inputs. The characterization of dissolved inorganic nitrogen (DIN) and DON processing along the pathways of surface/subsurface flow and wet deposition is also not well constrained. This dissertation work used stable isotope techniques to complete a comprehensive investigation of DIN and DON profiles, transformations, and sources across the hydrosphere (ground, surface, pore and rainwater) of a semi-arid estuary system (Baffin Bay, TX). Rainwater directly deposited 5.2 kg N/(ha*yr) to the watershed and had relatively low concentrations and varied nitrogen isotopic compositions of NH4+ (~27 µM; -10-7‰), NO3- (~17 µM; -7-10‰), and DON (~11 µM; -7-18‰). Isotope mixing model results implied agriculture and vehicle emissions as the two primary competing sources to ambient NH3 in the atmosphere. Vehicles were the dominant contributors to NOx emissions, however intermittent sources (e.g., lightning and biomass burning) rivaled vehicle emission during different seasons. Vehicle, fertilizer, and marine emissions were primary contributors to atmospheric DON and higher secondary DON formation contributions were observed when agriculture and/or biomass burning emissions were more prevalent. Tributaries in the watershed had varied NH4+ (0-300 µM), NO3- (0-272 µM), and DON (1-302 µM) concentrations that can reach the bay through riverine discharge. Several DIN hotspots were found at downstream WWTP outfalls, indicating wastewater contamination, which was consistent with the DON and NO3- dual isotope mixing model results. Groundwater had high NO3- (~1064 µM) and DON (~65 µM) concentrations, which could reach the bay through subsurface discharge. The varied ?15N-NO3- (7-56‰) and ?18O-NO3- (4-25‰) values in groundwater evidenced varying processes (i.e., anaerobic denitrification, aerobic denitrification and nitrification) affecting the NO3- isotopic composition. Isotope mixing model results suggested septic effluent and agriculture as the main NO3- and DON sources in the groundwater. As a result of source loadings and subsequent processing along the surface and subsurface runoff transport pathways, Baffin Bay surface water had high DON concentrations but low NO3- (~0.3 µM) and NH4+ (~2.3 µM) concentrations. The high NO3- and/or NH4+ concentrations in the groundwater and tributaries might be further processed by dissimilatory NO3- reduction to NH4+, denitrification, nitrification, and assimilation along the pathways and/or in the bay. Surface water had ?15N-DON values of 8‰ and significant negative ?15N-DON: ln[DON] correlations were intermittently observed, suggesting DON consumption. Isotope mixing model results suggested wastewater and manure as the primary allochthonous sources and the autochthonous source can contribute 20-40% of DON to Baffin Bay. High NH4+ concentrations (~325 µM) and varied ?15N-NH4+ values (-9-20‰) were found in porewater. Porewaters displayed a negative NH4+: DON and a positive temperature: ln[NH4+] correlation and decreased ?15N-NH4+ values in the summer. This presumably indicated a temperature- or/and solar irradiance-dependent process (e.g., remineralization and photo-ammonification) producing NH4+ from DON/PON in the porewater. This study provides a comprehensive DIN and DON assessment within a coastal watershed and its associated nutrient delivery pathways. It provided insights to future nutrient control management and watershed restoration plans in the region. This isotopic approach and assessment to investigate N sources and processing can be applied to similar systems worldwide and our findings add to the body of work needed to enhance global understanding of N biogeochemical cycles.Physical and Environmental SciencesCollege of Scienc
A nurse-led diabetic foot care education program for adult patients
No full textA dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Nursing Practice.Diabetes foot care education is essential to aid in the prevention of foot related complications especially in communities with lower socio-economic demographics. Community is where health happens, and access to health education can make a difference in the lives of individuals with diabetes who have to self-manage their illness. Objective: provide foot care education in a culturally congruent way with lecture, handouts, demonstration, and the incorporation of teach-back. Method: a single group pre/posttest design was used to evaluate change impact and teach-back was used to evaluate skills and tips learned. Results: 26 participants had an average pretest score of 85% and an average post test score of 91% indicating an average increase in knowledge of 6 points. The average number of teach-back skills was 7.5. Although results were not statistically significant (p = .062), the ease of implementation and low cost of the project implies clinical and practical significance. Conclusion: providing diabetic foot care education in a community setting, in the language needed, at an appropriate literacy level, and incorporating teach-back method can increase knowledge of diabetes foot care and foot self-care skills.
