Show moreMy paper critically examines the U.S. home health aide industry through a feminist analysis of the relationships between home health aides, their patients, and the medical establishment. This research adds to current feminist scholarship on care work by focusing on the social, legal and personal relationships impacting the lives of those who give and receive care. According to the U.S. Bureau of Labor Statistics, home health aides are one of the lowest paid members of the healthcare field, and hiring agencies expect high turnover rates and few long-term careers. Aides provide basic care services such as bathing, dressing, and meal preparation for elderly and disabled clients. This industry is situated at the boundary between the public/private divide, leading to many challenges as paid care work is performed in private homes. Historically, care work was an expected duty done freely by the women of the family, but today much of the vital intimate caring labor is relegated to a workforce made up predominantly of immigrant and women of color. I add to feminist debates on gender and caregiving using intersectional analysis and standpoint theory; discussing how race and class impact women’s ability to care for their own families as they are paid very little caring for others. I address the implications for the medical establishment to promote sustainable caring relationships between care recipients and providers, and conclude that caring for the caregiver is essential in order to ensure a successful model for patient care.

Show moreInvasive predaceous ants can cause chaos in their new habitats by competing for resources, increasing or decreasing preys or predators, and even threatening the next generation of offsprings. The red imported fire ant RIFA, Solenopsis invicta is a generalist, omnivorous exotic ant from South America. It has been causing ecological, agricultural, and economical havoc in the USA and other parts of the world. Solenopsis invicta preys on pipped eggs and hatchlings of ground nesting birds and reptiles and they are also found on sea turtle nesting beaches. We hypothesized that there will be a change in the fire ant species distribution at Sandy Point National Wildlife Refuge SPNWR after the first follow-up survey done in 2010, and at Jack Bay after the baseline study in 2011; both nesting beaches are in St Croix, US Virgin Islands. Baited index cards with tuna were set out for approximately two hours then ants were collected in separate marked bags. They were frozen then preserved in ethanol and finally identified. Solenopsis invicta was the most common exotic species at SPNWR. It was significantly more abundant p0.02 than the other fire ant species, Solenopsis geminata which was more abundant in both the 2010 survey and the baseline survey in 2006 at SPNWR. Neither of the fire ant species was found at Jack Bay. This increase in RIFA can become a serious threat to the next generation of sea turtles if its abundance continues to increase at SPNWR.

Title: Characterizing Immune Cells of Atlantic Bottlenose Dolphins.
Creator: Bible, Brittany, Zeng, Menghua, Graduate College, Tamjidi, Saba, Bossart, Gregory D., Nouri-Shirazi, Mahyar
Abstract/Description: Background: Marine mammals are ideal sentinel species for human health due to exposure to the same oceans and consumption of the same foods. There have been many studies which demonstrate that wild Atlantic Bottlenose Dolphins are exposed to high levels of contaminants which lead to a suppressed immune system and are therefore more susceptible to opportunistic infections, many of which are zoonotic diseases. However, nearly no research has been done on determining defects in the immune cell...
Show moreBackground: Marine mammals are ideal sentinel species for human health due to exposure to the same oceans and consumption of the same foods. There have been many studies which demonstrate that wild Atlantic Bottlenose Dolphins are exposed to high levels of contaminants which lead to a suppressed immune system and are therefore more susceptible to opportunistic infections, many of which are zoonotic diseases. However, nearly no research has been done on determining defects in the immune cell population of dolphins, especially Dendritic Cells DCs that are essential for initiating an immune response. Hypothesis: We hypothesize phenotypic and functional differences in the Peripheral Blood Mononuclear Cells PBMC, including DC precursors, of wild dolphins as compared to managed dolphins. Methods: Specifically in this study, we have used terrestrial-specific antibodies and growth factors to characterize immune cells in PBMC and to generate monocyte-derived DCs. Results: We have identified cross-reactive terrestrial antibodies that could detect immune cell subsets within PBMC, including B cells, T cells, NK cells, monocytes and APCs. Interestingly, using these antibodies we found significant changes in immune cell subsets within PBMC of wild and managed dolphins. Finally among the terrestrial DC growth factors tested we found rat GM-CSF and IL-4 generated DCs expressing higher levels of CD11c, CD14, CD40, CD80, CD86, MHC I and MHC II. Conclusion: Our findings allow us to further study defects in the immune cells, especially DCs, in response to environmental contaminants.

Title: Chitinase-3 like-protein-1 CHI3L1 expression associated with pulmonary inflammation accelerates breast cancer metastasis.
Creator: Libreros, Stephania, Areas, Ramon Garcia, Iragavarapu-Charyulu, Vijaya, Graduate College
Abstract/Description: Disseminated metastasis accounts for a majority of breast cancer deaths. Recently, elevated serum levels of a glycoprotein known as chitinase-3 like-protein-1 CHI3L1 has been correlated with poor prognosis in both breast cancer and asthmatic patients. We have combined mouse models of breast cancer and pulmonary inflammation to determine if CHI3L1 associated pulmonary inflammation accelerates metastasis.

Show moreDisseminated metastasis accounts for a majority of breast cancer deaths. Recently, elevated serum levels of a glycoprotein known as chitinase-3 like-protein-1 CHI3L1 has been correlated with poor prognosis in both breast cancer and asthmatic patients. We have combined mouse models of breast cancer and pulmonary inflammation to determine if CHI3L1 associated pulmonary inflammation accelerates metastasis. We found that allergic pulmonary inflammation significantly enhances primary tumor growth in 4T1, 4T07 and 67NR mammary tumors by 10- fold, while decreasing survival. 4T1 tumor bearers with allergic pulmonary inflammation showed a 100-fold increase in metastatic tumor formation. We also assessed CHI3L1 levels and myeloid cells in the lungs of wild type and CHI3L1 knockout mice with allergic pulmonary inflammation and 4T1 mammary tumors. CHI3L1 levels were higher in the lungs of mammary tumor bearers with allergic pulmonary inflammation and correlated with increased metastasis. Wild type mammary tumor bearers with allergic inflammation had higher numbers of myeloid cells in the lungs in comparison to CHI3L1 knockout tumor bearers with allergic pulmonary inflammation. CHI3L1 knockout mice tumor bearers had significantly fewer myeloid cells in the lungs, decreased tumor growth and metastasis, along with increased survival. We propose that increased CHI3L1 in the lungs attracts myeloid cells that promote tumor growth and breast cancer metastasis.

Show moreQuantitative assessment of substrate classification for sand properties is needed for land management and conservation. Establishing a sand spectral library is the first step in this process. Hyperspectal analysis allows for rapid, nondestructive data acquisition. This process uses an ASD spectrometer in a laboratory setting with an artificial light source to collect the spectra. Sand collected worldwide was also analyzed for grain size and composition. Development of spectral libraries of sand is an essential factor to facilitate analytical techniques to monitor coastal problems including erosion and beach nourishment. This in turn can affect various flora and fauna which requires specific substrate to grow, nest, or live. Preliminary results show that each sand sample has a unique signature that can be identified using hyperspectral data.

Show moreThe gopher tortoise (Gopherus polyphemus) is a threatened keystone species of the Southeastern United States. Increasing urban encroachment and tortoise translocation increases the risk of disease transmission. Prior work at Florida Atlantic University suggested resident gopher tortoises had high tick burdens. To investigate ticks as potential disease vectors, two sites were examined. The Florida Atlantic University Preserve (FAUP); managed by mowing and herbicides and Jonathan Dickinson State Park (JDSP); managed by fire. We hypothesized that gopher tortoises in the FAUP will be infected by heavier hemoparasite loads, potentially causing anemia, when compared to JDSP. To detect hemoparasites, blood was collected from tortoises at FAUP and JDSP. Blood smears revealed intracellular parasites and inclusions at both sites. Packed cell volumes were done to assess whether tortoises were anemic; results found tortoises were not anemic during that sampling period. This study will provide baseline data for blood-borne infections in two south Florida gopher tortoise populations.

Show moreClass imbalance is a frequent problem found in bioinformatics datasets. Unfortunately, the minority class is usually also the class of interest. One of the methods to improve this situation is data sampling. There are a number of different data sampling methods, each with their own strengths and weaknesses, which makes choosing one a difficult prospect. In our work we compare three data sampling techniques Random Undersampling, Random Oversampling, and SMOTE on six bioinformatics datasets with varying levels of class imbalance. Additionally, we apply two different classifiers to the problem 5-NN and SVM, and use feature selection to reduce our datasets to 25 features prior to applying sampling. Our results show that there is very little difference between the data sampling techniques, although Random Undersampling is the most frequent top performing data sampling technique for both of our classifiers. We also performed statistical analysis which confirms that there is no statistical difference between the techniques. Therefore, our recommendation is to use Random Undersampling when choosing a data sampling technique, because it is less computationally expensive to implement than SMOTE and it also reduces the size of the dataset, which will improve subsequent computational costs without sacrificing classification performance.

Title: Comparison of growth patterns in three species of juvenile sea turtles.
Creator: Pate, Jessica Hope, Salmon, Michael, Wyneken, Jeanette, Graduate College
Abstract/Description: Sea turtles are most vulnerable to predators during early growth when they are small and relatively defenseless. Predation risk might be reduced by evolving effective behavioral as well as morphological defenses. Loggerhead Caretta caretta and green turtle Chelonia mydas neonates hide in weed lines. They also become wider faster than they increase in length, a pattern of positive allometry that may function to minimize the time during growth when they are vulnerable to gape-limited predators....
Show moreSea turtles are most vulnerable to predators during early growth when they are small and relatively defenseless. Predation risk might be reduced by evolving effective behavioral as well as morphological defenses. Loggerhead Caretta caretta and green turtle Chelonia mydas neonates hide in weed lines. They also become wider faster than they increase in length, a pattern of positive allometry that may function to minimize the time during growth when they are vulnerable to gape-limited predators. Virtually nothing is known about how young leatherbacks grow which might reduce their vulnerability to predators. To find out, we reared 30 hatchlings from 10 nests in the laboratory for up to 14 weeks, post-emergence. Once weekly, each turtle’s body proportions straight line carapace length, SCL; straight line carapace width, SCW were measured to yield an observed pattern of growth. That observed growth pattern was compared to an expected pattern in which the turtles retained their hatchling proportions as they grew larger isometric growth. We found that all of the leatherbacks showed allometric growth as their SCW increased more rapidly than their SCL. Thus as they grew, leatherbacks became proportionally wider, though this growth was not as pronounced as seen in loggerheads and green turtles. We also modeled vulnerability to gape-limited predators. Leatherbacks, like loggerhead and green turtles, were less vulnerable to predation when growing allometrically. These results provide insight into a little know sea turtle life stage and aids in understanding how morphology in early development may reduce predation risk.
