On and off the stage at Atlanta Greek Picnic: Performances of collective black middle-class identities and the politics of belonging

This dissertation presents a thick ethnography that engages in the micro-analysis of the situationality of black middle-class collective identification processes through an examination of performances by members of the nine historically black sororities and fraternities at Atlanta Greek Picnic, an annual festival that occurs at the beginning of June in Atlanta, Georgia. It mainly attracts undergraduate and graduate members of these university-based organizations, as they exist all over the United States. This exploration of black Greek-letter organization (BGLO) performances uncovers processes through which young black middle-class individuals attempt to combine two universes that are at first glance in complete opposition to each other: the domain of the traditional black middle-class values with representations and fashions stemming from black popular culture. These constructions also attempt to incorporate—in a contradiction of sorts— black popular cultural elements in the objective to deconstruct the social conservatism that characterizes middle-class values, particularly in relation to sexuality and its representation in social behaviors and performances. This negotiation between prescribed v middle-class values of respectability and black popular culture provides a space wherein black individuals challenge and/or perpetuate those dominant tropes through identity performances that feed into the formation of black sexual politics, which I examine through a variety of BGLO staged and non-staged performances. ^

Making life choices : facilitating identity formation in young adults

This dissertation makes a contribution to the growing literature on identity formation by formulating, implementing, and testing the effectiveness of a psychosocial intervention, the Making Life Choices (MLC) Workshops, designed to facilitate the process of identity formation. More specifically, the MLC Workshops were designed to foster the development and use of critical cognitive and communicative skills and competencies in choosing and fulfilling life goals and values. The MLC Workshops consist of a psychosocial group intervention that includes both didactic and group experiential exercises. The primary research question for this study concerned the effectiveness of the MLC Workshop relative to a control condition. Effectiveness was evaluated on two levels: skills development and reduction of distress. First, the effectiveness of MLC in fostering the development of critical competencies was evaluated relative to a control condition, and no statistically significant differences were found. Second, the effectiveness of MLC in decreasing life distress was also evaluated relative to the control condition. While participants in the MLC workshop had no significant decrease in distress, they did have statistically significant improvement in life satisfaction in the Personal Domain.

Effect of gamma-irradiation on total organic carbon and trihalomethane formation potential

This research was conducted to study the use of radiation in water treatment as an alternative to chlorination which has caused health concerns due to the formation of harmful disinfection by-products. Groundwater solutions from the Biscayne aquifer were radiated with Cobalt-60 gamma radiation and studied for changes in dissolved organic carbon (DOC), UV absorbance at 254 nm (UV254), fluorescence and trihalomethane formation potential (THMFP). Molecular fractionations were conducted by ultrafiltration. Effect of the combination of radiation/peroxide was studied for DOC and UV254. Radiation showed significant removal in DOC and THMFP. Similar results were seen in the fluorescence and UV absorbance experiments. Radiation/peroxide did not improve the DOC removal. Radiation of the groundwater samples broke the larger molecular weight fractions in to smaller fractions.
