The purpose of this thesis was to explore selected works from William Shakespeare, Edmund Spenser, and John Keats, in order to expose textual instances of feminist thought. This analysis was aided with feminist theorists falling under the main strains of queer theory, materialism, and gender performance. Specifically, this thesis focused on the ways in which women, particularly virgin daughters, were viewed as property by their male kin. It also looked at how these women engaged in various symbolic masquerades and/or actual cross-dressing as a response to the aforementioned phenomenon. Finally, the thesis exposed how these masquerades can be construed as a queering of identity—manifested through reversals of power and rejection of patriarchal institutions like marriage.

The contamination of water bodies with toxic substances causes a decrease in water quality, representing a risk to public health. In this context, human activities are generally seen as the main sources of water degradation. However, elements found naturally in the environment can also compromise water quality. Thus, the Boqueirão‘s dam, located in the municipality of Parelhas (RN, Brazil), was chosen as area for the development of this study, as its geological region is rich in the emission of natural ionizing radiation that produces byproducts like lead and Radon. Moreover, the area has a strong human influence that enhances the risks of pollutant discharge in this body of water.Thus, the objectives of this study were centered (i) in the analysis of risk perception in the city of Parelhas (RN/Brasil) due to the use of the water from the Boqueirão Dam; and (ii) in the assessment of water quality in the Dam using methods that quantify, mainly, heavy metals and radiation levels, as well as these toxics potential of inducing mutations on genetic material. The analysis of risk perception showed that the population in the city of Parelhas can perceive a risk in using the water from the dam and that they can recognize factors that influence the water quality. Regarding the second objective, the set of data point to the contamination of the Dam by heavy metals, as well as levels of radioactive parcicles and Radon – also present in high concentrations in outdoor air and on soil. Thus, it is possible to infer that the population residing in this area is subjected to injuries caused by exposure to natural and anthropogenic contamination. Our findings corroborate with the perception of the population regarding the risks associated with the use of the Dam for several types of activities. It is expected that the information gathered in this study can substantiate activities and future researches in this semiarid region in the Rio Grande do Norte/Brazil. Also, that the set of data can enable a better understanding of the specific toxicological scenario of risk found for the population and the effect of the contamination for the biota, which aids the development of a future risk assessment and a consequent management of this local issue.

Reproduction is an essential part of humans species’ existence and survival. We are interested in securing it, and having a direct interest in the reproduction of those with whom we have strong genetic relationship. Trivers (1974) featured the parent-offspring conflict, as a divergence about the parents’ investment, which has been mainly studied in the early stages of children’s development. However, the divergence in investment can also be expressed at the time of the reproductive decisions of the offspring. Thus, we investigated whether parents and children have conflicting interests regarding reproductive expectations of the children, understanding reproductive expectations as desired age to marry, have children, have sexual intercourse and desired amount of children. We found that parents and children disagree on some of these points, we also find a more conservative expectation when it comes to daughters, reiterating the daughter-guarding hypothesis. When we consider how much help would be given towards the up bringing of a grandson, we found a clear variation according to the age of the baby's parents: the younger the baby’s parents are, the larger the amount of assistance would be provided by grandparents. Considering the amount and quality of offspring and conditions of reproduction, parental investment is an element that presents itself closely linked to the history of the subject's life. Parents are the first to communicate to children how the environment in which they are inserted is presenting itself. As the life history is closely linked with reproduction, and, therefore, with parental investment, we intend to investigate whether there is a correlation between aspects of the individuals’ history of life (unpredictability and parental care) and their reproductive expectations, seeking further assess on whether there is relationship between parents' life history and their reproductive expectations for their children. We find evidence that partially confirm our expectations; we find relationships of some elements of reproductive expectations with indicators of unpredictability and parental care. The experiences of parents also reflected in their expectations for their children, with a more present correlation to their expectations for daughters. From our results, we find evidence that parent-offspring conflict appears in the reproductive expectations of children and relates to aspects of individuals’ life history.

The key aspect limiting resolution in crosswell traveltime tomography is illumination, a well known result but not as well exemplified. Resolution in the 2D case is revisited using a simple geometric approach based on the angular aperture distribution and the Radon Transform properties. Analitically it is shown that if an interface has dips contained in the angular aperture limits in all points, it is correctly imaged in the tomogram. By inversion of synthetic data this result is confirmed and it is also evidenced that isolated artifacts might be present when the dip is near the illumination limit. In the inverse sense, however, if an interface is interpretable from a tomogram, even an aproximately horizontal interface, there is no guarantee that it corresponds to a true interface. Similarly, if a body is present in the interwell region it is diffusely imaged in the tomogram, but its interfaces - particularly vertical edges - can not be resolved and additional artifacts might be present. Again, in the inverse sense, there is no guarantee that an isolated anomaly corresponds to a true anomalous body because this anomaly can also be an artifact. Jointly, these results state the dilemma of ill-posed inverse problems: absence of guarantee of correspondence to the true distribution. The limitations due to illumination may not be solved by the use of mathematical constraints. It is shown that crosswell tomograms derived by the use of sparsity constraints, using both Discrete Cosine Transform and Daubechies bases, basically reproduces the same features seen in tomograms obtained with the classic smoothness constraint. Interpretation must be done always taking in consideration the a priori information and the particular limitations due to illumination. An example of interpreting a real data survey in this context is also presented.

Obesity and overweight disproportionately impact Black American adolescent females—placing them at a lifetime of elevated physical health risks. Despite this burden, the literature that explores the contributors to obesity and overweight among Black American adolescent females remains limited and unclear. This dissertation aims to develop knowledge related to obesity and overweight in Black American adolescent females, by appraising the current understanding of factors that contribute to their obesity and overweight, and explicating the everyday social influences on dietary practices. The primary study conducted for this dissertation used a mixed method, multiple case study design to examine the mother, daughter, and other household contributors to Black American adolescent daughters’ everyday practices of food consumption, acquisition, preparation, and planning. Findings reveal the importance of understanding the complex and dynamic ways mothers and other household members contribute to a holistic view of everyday dietary practices among adolescent daughters. By deeply examining the nuanced ways the multiple cases varied, context-dependent knowledge essential to understanding the complicated health challenge of obesity was produced. Subsequently, recommendations are provided for health providers and scholars to more holistically approach and examine obesity—particularly among populations who are disproportionately affected.

The present study examines how mothering and fathering impact child academic outcomes in divorced and intact families, and if there are unique influences of mothering and fathering variables for sons and daughters. An ethnically diverse sample of 1,714 university students from Florida International University (n=1371) and Florida State University (n=343) responded to measures on a questionnaire that included the Nurturant Fathering and Mothering Scales (Finley & Schwartz, 2004; Schwartz & Finley, 2005; Finley & Schwartz, 2006), the Mother and Father Involvement Scales (Finley, Mira, & Schwartz, 2008), demographic measures, and academic outcome measures. In intact families, mothering and fathering variables were significantly correlated with each other, and positively correlated with child academic outcomes including grades, GPA, academic satisfaction, and academic importance. In divorced families, mothering and fathering variables were not correlated with each other. Furthermore, when analyzing divorced families, significant effects were found for both parent and child gender. Mothering variables were found to have the greatest positive impact for sons’ academic outcomes. Maternal nurturance and maternal involvement were correlated positively with academic outcomes for sons from divorced families and accounted for 3-4% of the unique variance explained. Consistently, desired mother involvement, how much involvement the child wished they had received, was negatively correlated with academic outcomes for sons from divorced families and accounted for 10-15% of the unique variance explained. This means that when the amount of maternal involvement that sons in divorced families received matched or exceeded their desired level of involvement, sons had more positive academic outcomes including grades, GPA, satisfaction with academics and academic importance. This suggests that in intact family forms, nurturant and involved mothering and fathering have a positive effect on academic outcomes for sons and daughters. In divorced family forms, the effects of fathering on child academic outcomes were not significant. Therefore, in divorced families, the positive effects fathering on academic outcomes of sons and daughters drop out, and mothers are uniquely important for sons’ academic success.
