ABSTRACT
Computerized mental health interventions have the potential to address existing mental health care disparities in rural communities. The aim of this study was to conduct an exploratory examination on the acceptability of an interactive computerized cognitive behavior therapy program to reduce depressive symptoms for adults in a rural Western state. Partnering with the land-grant university Extension system and a state non-profit organization, we identified and interviewed 18 key informants and conducted 19 focus groups in 15 rural communities to ascertain attitudes and perspectives about the program. Key informants were provided access to the Thrive program prior to the interviews. Focus group participants were provided a brief demonstration of the program and asked to provide feedback. Content analyses of interview and focus group transcripts yielded four general themes of program acceptability: privacy, accessibility, user-friendliness, and cultural inappropriateness. Overall, participants indicated that the Thrive program would be useful for many in their communities. They also reported that the program could be improved by making videos that better represent rural community members' lifestyles and experiences. The study team members acted on these findings to improve the Thrive program for rural Western populations.
ABSTRACT
A pilot-scale (1,000 L) continuous flow microbial electrolysis cell was constructed and tested for current generation and COD removal with winery wastewater. The reactor contained 144 electrode pairs in 24 modules. Enrichment of an exoelectrogenic biofilm required ~60 days, which is longer than typically needed for laboratory reactors. Current generation was enhanced by ensuring adequate organic volatile fatty acid content (VFA/SCOD ≥ 0.5) and by raising the wastewater temperature (31 ± 1°C). Once enriched, SCOD removal (62 ± 20%) was consistent at a hydraulic retention time of 1 day (applied voltage of 0.9 V). Current generation reached a maximum of 7.4 A/m(3) by the planned end of the test (after 100 days). Gas production reached a maximum of 0.19 ± 0.04 L/L/day, although most of the product gas was converted to methane (86 ± 6%). In order to increase hydrogen recovery in future tests, better methods will be needed to isolate hydrogen gas produced at the cathode. These results show that inoculation and enrichment procedures are critical to the initial success of larger-scale systems. Acetate amendments, warmer temperatures, and pH control during startup were found to be critical for proper enrichment of exoelectrogenic biofilms and improved reactor performance.
