Relational predictors of condom use among adolescents in outpatient substance abuse treatment

Past HIV interventions have been critiqued for their failure to incorporate relational factors linked to condom use. Furthermore, few studies have focused on the relational context of sexual risk behavior among adolescents at elevated risk for HIV/STI exposure in the context of substance use. Therefore, this study evaluated the influence of three key relational factors (rejection sensitivity, intimacy dating goals, intercourse-related anxiety) salient for understanding condom use among adolescents in outpatient substance abuse treatment in South Florida. Structural equation modeling was used to test relational factors as direct and indirect predictors of condom use. Specifically, the current study investigated the influence of rejection sensitivity and intimacy dating goals on percentage of protected intercourse, with intercourse-related anxiety modeled as a mediator of this association. ^ Results obtained from the hypothesized structural model suggest rejection sensitivity and intimacy dating goals are significant predictors of percentage of protected intercourse. As expected, rejection sensitivity was related to lower levels of percentage of protected intercourse via heightened levels of intercourse-related anxiety and was not related directly to percentage of protected intercourse. Intercourse-related anxiety was indicated as a partial mediator between rejection sensitivity and percentage of protected intercourse. In contrast, intimacy dating goals was related to lower levels of percentage of protected intercourse directly. The findings demonstrate the importance of relational factors in condom use among adolescents in outpatient substance abuse treatment. Levels of protected intercourse are likely to increase when relational factors are targeted among adolescents in this high-risk population. Implications for prevention strategies targeting this high-risk subgroup of adolescents are discussed. ^

Taxonomy and distribution of taxa in the genus Gomphonema from the Florida Everglades, U.S.A.

Located at a subtropical latitude, the expansive Florida Everglades contains a mixture of tropical and temperate diatom taxa, as well as a unique flora adapted to the calcareous, often excessively hot, seasonally flooded wetland conditions. This flora has been poorly documented taxonomically, although diatoms are recognized as important indicators of environmental change in this threatened ecosystem. Gomphonema is a dominant genus in the freshwater marsh, and is represented by highly variable species complexes, including Gomphonema gracile Ehrenberg, Gomphonema intricatum var. vibrio Ehrenberg sensu Fricke, Gomphonema vibrioides Reichardt & Lange-Bertalot and Gomphonema parvulum (Kützing) Grunow. These taxa have been shown to exhibit wide morphological variation in other regions, resulting in considerable nomenclatural confusion. We collected Gomphonema from 237 sites distributed throughout the freshwater Everglades and used qualitative and quantitative morphological data to identify 20 distinguishable populations. Taxonomie assignments were based on descriptions and/or observations of type material of relevant taxa when possible, but deviations from original morphological range descriptions were common. We then compared morphological variation in Everglades Gomphonema taxa to that reported for the same taxa in other regions and suggest revisions of taxonomie concepts when necessary.

A Study of the Relational Component in an Academic Advisor Professional Development Program

The purpose of the study was to investigate the significance of the relational component of academic advisor training and development in the learning opportunities of the professional development program and the advisors’ evaluation score at Florida International University.
