Qualitative analysis of the ACTION program

This study used a qualitative methodology to examine treatment outcome and mechanisms of change from the perspective of the participants in a group cognitivebehavioral therapy intervention for depressed girls (i.e., the ACTION program). Data were collected from seventeen participants using semi-structured interviews. Seventeen initial and seven follow-up interviews were conducted. Interviews were transcribed and analyzed using the grounded theory approach. A theoretical model emerged from the data that explained mechanisms of change in relation to treatment outcome and evaluation. Prior to treatment, all participants were diagnosed with a depressive disorder. At post-treatment, approximately 88% of the sample no longer met criteria for depression. Thus, the ACTION program demonstrated a high rate of efficacy. Additionally, all of the participants described treatment as helpful. Level of helpfulness varied from high to low, with most participants rating treatment as very helpful, and depended on the ways in which the intervention produced positive change in the following areas: stressors, stressor management strategies, emotions, cognitions, and social support. Participants evidenced high levels of pre-treatment stressors, particularly in the interpersonal domain, and low levels of social support. Passive, emotion-focused strategies were used to manage these difficulties; however, they were largely ineffective. Not being able to resolve stressors successfully led participants to experience unpleasant emotions and negative ways of thinking. Together, these variables resulted in high levels depression prior to treatment. At post-treatment, most participants experienced several positive changes, including decreased stressors, increased effectiveness of stressor management strategies, elevated mood, and a more positive outlook. These changes were attributed to the acquisition and application of the core treatment components by the majority of participants. Some participants also experienced an increase in social support, which was associated with characteristics of the treatment structure. Thus, the two most important variables in relation to treatment outcome and evaluation were specific mechanisms of change (i.e., treatment components) and non-specific therapeutic factors (i.e., treatment structure). In addition, treatment outcome was also influenced by participant characteristics. Participants that held unrealistic expectations, were not ready for change, or engaged in limited problem-sharing experienced fewer positive changes over the course of treatment.Educational Psycholog

From Purpose and Scope: "The Billings Quadrangle (2º), Montana and Wyoming, was evaluated to identify geologic units and to delineate areas that exhibit characteristics favorable for uranium deposits that could contain at least 100 tons U3O8 in rocks with an average grade of not less than 100 ppm U3O8. Surface and subsurface data were used to evaluate all geologic environments to a depth of 1500 m (5,000 ft).

Photoferrotrophy, deposition of banded iron formations, and methane production in Archean oceans

Banded iron formation (BIF) deposition was the likely result of oxidation of ferrous iron in seawater by either oxygenic photosynthesis or iron-dependent anoxygenic photosynthesis-photoferrotrophy. BIF deposition, however, remains enigmatic because the photosynthetic biomass produced during iron oxidation is conspicuously absent from BIFs. We have addressed this enigma through experiments with photosynthetic bacteria and modeling of biogeochemical cycling in the Archean oceans. Our experiments reveal that, in the presence of silica, photoferrotroph cell surfaces repel iron (oxyhydr)oxides. In silica-rich Precambrian seawater, this repulsion would separate biomass from ferric iron and would lead to large-scale deposition of BIFs lean in organic matter. Excess biomass not deposited with BIF would have deposited in coastal sediments, formed organic-rich shales, and fueled microbial methanogenesis. As a result, the deposition of BIFs by photoferrotrophs would have contributed fluxes of methane to the atmosphere and thus helped to stabilize Earth's climate under a dim early Sun
