The effect of nutrient limitations on the production of extracellular polymeric substances by drinking-water bacteria
(2013-05) Evans, Ashley Nichole; Kirisits, Mary Jo
Biological filtration (biofiltration) of drinking-water is gaining popularity due the potential for biodegradation of an array of contaminants not removed by traditional drinking-water processes. However, previous research has suggested that biomass growth on biofilter media may lead to increased headloss, and thus, greater energy and water requirements for backwashing. Research has suggested that the main cause of headloss might be due to extracellular polymeric substances (EPS) rather than the bacterial cells themselves. As EPS production has been shown to increase under nitrogen- and phosphorus-limited or -depleted conditions, the goal of this research was to add to the body of knowledge regarding biofiltration by studying the relationship between EPS production and nutrient limitations in drinking-water. Batch experiments with a synthetic groundwater were run with a mixed community of drinking-water bacteria under nutrient-balanced (a molar carbon to nitrogen to phosphorus ratio [C:N:P] of 100:10:1), nutrient-limited (e.g., C:N:P of 100:10:0.1), and nutrient-depleted conditions (C:N:P of 100:0:1 or 100:10:0). After 5 days, growth was measured as the optical density at 600 nanometers (OD600), and the concentrations of free and bound carbohydrates and proteins, the main components of EPS, were measured. In batch experiments with 2.0 and 0.2 g/L as carbon (mixture of acetic acid, mannitol and sucrose) increases in EPS production per OD600 and decreases in growth were noted under nutrient-depleted conditions. When the same experiments were conducted with a pure culture of Bacillus cereus, bound polysaccharides normalized to OD600 increased under nitrogen- and phosphorus-depleted conditions. Since previous research suggested that Bradyrhizobium would be an important player in EPS production in drinking-water biofilters, similar batch experiments were conducted with Bradyrhizobium. However, due to experimental challenges with Bradyrhizobium japonicum USDA 110, differences in EPS production under nutrient limitations could not be reliably assessed. Additional work is required with Bradyrhizobium. Recommendations for future work include the replication of these batch conditions in steady-state chemostats containing biofilm attachment media and in bench-scale columns. Additionally, future work should include experiments at carbon concentrations as low as 2 mg/L to match typical carbon concentrations in drinking-water biofilters.

Sexual Experiences and Mental Health in Men: The Ganymede Study
(2019-05-15) Ounsinegad, Seena; Meston, Cindy M.
Sexual violence is a prominent issue in the U.S. and worldwide. Although the majority of research has focused on women, 1 in 6 men in the U.S. have experienced sexual violence, and this statistic is likely an underestimate due to markedly low rates of men identifying and reporting these experiences as sexual assault, rape, or sexual abuse. The current study investigates the ways in which nonconsensual sexual experiences (NSEs) affect men’s subjective mental health and attitudes toward help-seeking behaviors later in life, while considering the roles of hegemonic masculinity, patriarchal social roles, and minority group membership (e.g., sexual orientation). An online survey was administered to both community (U.S.; n = 108) and undergraduate (University of Texas at Austin; n = 49) samples. A series of multivariate regression analyses were used to assess the amount of variation in outcome variables that could be explained by NSEs and minority status. Findings support predictions that NSEs have a negative impact on subjective mental health and attitudes toward physical health help-seeking behaviors, and that there is a combined effect of NSEs and minority status on support preferences, such that NSEs are detrimental to inclinations to seek support in this relationship. However, the relationships between NSEs and mental health help-seeking behaviors, and the effects of minority status on the other outcomes, should be studied in more detail in replications. These results suggest the need for treatment providers to address the intersectionality of sexual violence and sexual minority status of men as barriers to treatment, and the necessity of considering this in the application and development of treatment options for this population.
The Social Value of Children: A Cross Cultural Examination of Infertility in Japan and Nigeria
(2020-05) Turner, Ilanit
We often hear about the lengths that a woman will go to hide or rid herself of an unwanted pregnancy. Rarely do we learn about the plight of the childless woman. This expository paper takes a look into the lives of infertile women in the developed and developing world using Japan and Nigeria as representative nations. In doing so, this paper analyzes the social value of children between societies. The work explores the respective causes and social consequences of infertility and the possible treatments- both orthodox Western and traditional folk- made available in each place. Japan and Nigeria’s comfortably close population sizes and infertility rates make for a compelling comparative analysis. There are significant differences in each country for causes and treatments although the overlaps are just as crucial. Many Japanese women learn too late that they are too old to carry children by the time they realize they want a family. In Nigeria, many infertile women face STDs and other infections or scarring that can otherwise be cured but they do not have access to necessary medical services. In essence, Japanese women are a day late and Nigerian women are a dollar short. Both countries have their respective types of ethnomedicine that many women turn to first. Western therapies like assisted reproductive technology (ART) are mutually perceived as a last resort. Stigma, however, remains just as caustic in both places. The role of social stigma creates a cascade of financial, medical and cultural consequences for childless women even when they seek treatment. This paper relies primarily on secondary sources including but not limited to local Japanese and Nigerian as well as international medical journals, ethnology and anthropology articles, and a few primary sources like literature and interviews from women directly experiencing infertility. The methodology of synthesizing the data is presented in a compare/contrast structure, looking at the differences and similarities between Japan and Nigeria.

The Effect of ADHD Diagnosis on Individual Identity Formation
(2021-05) Thompson, Morgan
Identity formation and the narratives we construct about who we are, why we perceive the world around us the way we do, and the lens through which we interpret our environment are all life long processes that are formed as we encounter experiences that shape us into the person that we have been, are, and will be. Categorization processes, including the diagnostic process, have a dramatic effect on how we perceive ourselves, as they define and associate us within broader social groups that we use to relate to and identify ourselves. Diagnoses shape our identities through a variety of mechanisms, including stigma, illness narratives, illness stereotypes, social factors, and institutions, and how we perceive our diagnoses has a dramatic impact on how we view ourselves. Mental health diagnoses have a particular impact on individual identity formation, as we view the mind as central to our individual identity. While identity is a well studied phenomenon, Attention Deficit Hyperactivity Disorder, or ADHD, is a fairly new diagnostic label. Not much literature has been dedicated to studying how the ADHD diagnosis affects the individual’s identity formation. Thus, my thesis enhances current research by describing the processes through which we form our identities, how we make sense of diagnoses, and the structures that form diagnoses in order to answer how ADHD diagnosis affects individual identity formation. After discussing the processes through which ADHD diagnosis is interpreted by the individual, my thesis discusses how to improve the diagnostic process and the ADHD label in hopes that refinement of these processes will benefit the individual. Study of how mental health and chronic diagnoses affect identity formation are essential for moral and social understanding of our diagnostic and social structures, as we should know how the diagnostic categories we create affect what it means to be us.
