Project description:The taxonomic relationship of Lentzea atacamensis and Lentzea deserti were re-evaluated using comparative genome analysis. The 16S rRNA gene sequence analysis indicated that the type strains of L. atacamensis and L. deserti shared 99.7% sequence similarity. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between the genomes of two type strains were 88.6% and 98.8%, respectively, greater than the two recognized thresholds values of 70% dDDH and 95-96% ANI for bacterial species delineation. These results suggested that L. atacamensis and L. deserti should share the same taxonomic position. And this conclusion was further supported by similar phenotypic and chemotaxonomic features between them. Therefore, we propose that L. deserti is a later heterotypic synonym of L. atacamensis.
Project description:Reviews by Devoe et al. (2022), Linardon et al. (2022), and Schneider et al. (2022) illustrate the profound impact the COVID-19 pandemic has had on people with eating disorders (EDs) or disordered eating (DE) and their families. However, there is a dearth of research on how the pandemic has affected individuals with marginalized identities, who have been historically underrepresented in ED/DE research. The few studies conducted to date suggest that people with marginalized identities, including people of color, LGBTQ + people, women, and people experiencing socioeconomic disadvantage, may have had even greater increases in EDs/DE than people without marginalized identities. In this Commentary, I discuss who is missing from research on EDs/DE during the COVID-19 pandemic, strategies for breaking down barriers to participation in research for diverse groups, and the implications of existing research findings for people with marginalized identities. Improved measurement of salient aspects of participants' identities and increased recruitment and retention of participants from diverse backgrounds is necessary to more fully understand the impact of the COVID-19 pandemic on all people affected by EDs and DE. Concurrently, increased access to affordable and culturally sensitive care is urgently required to meet the extensive treatment needs already documented.
Project description:In this commentary, I discuss some critical issues in the study by Greiff, S.; Stadler, M.; Sonnleitner, P.; Wolff, C.; Martin, R., "Sometimes less is more: Comparing the validity of complex problem solving measures", Intelligence 2015, 50, 100-113. I conclude that-counter to the claims made in the original study-the specific study design was not suitable for deriving conclusions about the validity of different complex problem-solving (CPS) measurement approaches. Furthermore, a more elaborate consideration of previous CPS research was found to challenge Greiff et al.'s conclusions even further. Therefore, I argue that researchers should be aware of the differences between several kinds of CPS assessment tools and conceptualizations when the validity of CPS assessment tools is examined in future research.
