title: Using an acceptance and commitment therapy app to reduce anxiety for students and employees

authors: Sargisson, Rebecca J.

subjects: Acceptance and commitment therapy

abstract: Smartphone applications may ensure greater access to services for the many people who experience anxiety and other psychological issues but do not receive adequate treatment. ACTCompanion® is a mHealth application that incorporates Acceptance and Commitment Therapy principles into daily exercises that assist the user to confront their negative internal experiences and work towards valued outcomes. We used a single-subject A-B design with nine students and 10 employees experiencing high daily anxiety. Participants completed a battery of questionnaires before and after app use. They completed the DAS-A regularly so we could monitor anxiety levels over time. Daily anxiety levels reduced in the intervention phase, and remained low for six participants for whom follow-up data were available. There was also a significant improvement in scores of anxiety, depression, stress, positive and negative effect, psychological flexibility, and mindfulness. Our results suggest that mHealth applications have potential to improve people’s psychological functioning.

title: The Trichoptera barcode initiative: a strategy for generating a species-level Tree of Life

authors: Zhou, Xin

subjects: Science & Technology

abstract: DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for phylogenetics, they can be beneficial to the completion of the Tree of Life. The barcode database for Trichoptera is relatively comprehensive, with data from every family, approximately two-thirds of the genera, and one-third of the described species. Most Trichoptera, as with most of life's species, have never been subjected to any formal phylogenetic analysis. Here, we present a phylogeny with over 16 000 unique haplotypes as a working hypothesis that can be updated as our estimates improve. We suggest a strategy of implementing constrained tree searches, which allow larger datasets to dictate the backbone phylogeny, while the barcode data fill out the tips of the tree. We also discuss how this phylogeny could be used to focus taxonomic attention on ambiguous species boundaries and hidden biodiversity. We suggest that systematists continue to differentiate between ‘Barcode Index Numbers’ (BINs) and ‘species’ that have been formally described. Each has utility, but they are not synonyms. We highlight examples of integrative taxonomy, using both barcodes and morphology for species description.
