Purpose This article provides within-group effect size benchmarks for RCTs of group-based Acceptance and Commitment Therapy (ACT) for adults with anxiety and/or depression. Methods A systematic literature search of RCTs of the group-based ACT intervention was conducted following PRISMA guidelines. Articles were selected based on predetermined eligibility criteria. Pre/post within-group effect sizes were calculated using the Glass approach, adjusted using Hedges g, and aggregated to produce separate benchmarks for symptoms of depression and anxiety for ACT and the comparison/control group(s). Results Results indicate that the average within-group pre/post effect sizes for the group-based ACT intervention is .59 (95% CI 0.37–0.81) for anxiety and .73 (95% CI 0.56–0.89) for depression. Discussion These benchmarks may be used by social workers to evaluate the effectiveness of their group-based ACT intervention and to guide clinical decision making.

We obtain the almost sure central limit theorem (ASCLT) of sample quantiles. Furthermore, based on the method, the ASCLT of order statistics is also proved.

Although plastic is considered an indispensable commodity, plastic pollution is a major concern around the world due to its rapid accumulation rate, complexity, and lack of management. Some political policies, such as the Chinese import ban on plastic waste, force us to think about a long-term solution to eliminate plastic wastes. Converting waste plastics into liquid and gaseous fuels is considered a promising technique to eliminate the harm to the environment and decrease the dependence on fossil fuels, and recycling waste plastic by converting it into monomers is another effective solution to the plastic pollution problem. This paper presents the critical situation of plastic pollution, various methods of plastic depolymerization based on different kinds of polymers defined in the Society of the Plastics Industry (SPI) Resin Identification Coding System, and the opportunities and challenges in the future.
