Tracking conflict and emotions with a computational qualitative discourse analytic support approach.

PLoS One 2021 13;16(5):e0251186. Epub 2021 May 13.

Digital Media Research Centre, Queensland University of Technology, Brisbane, Australia.

Accurate inferences of the emotional state of conversation participants can be critical in shaping analysis and interpretation of conversational exchanges. In qualitative analyses of discourse, most labelling of the perceived emotional state of conversation participants is performed by hand, and is limited to selected moments where an analyst may believe that emotional information is valuable for interpretation. This reliance on manual labelling processes can have implications for repeatability and objectivity, both in terms of accuracy, but also in terms of changes in emotional state that might go unnoticed.

Putting Stakeholder Engagement at the Center of Health Economic Modeling for Health Technology Assessment in the United States.

Pharmacoeconomics 2021 May 13. Epub 2021 May 13.

Innovation and Value Initiative, Alexandria, Virginia, USA.

While evidence generated from health economic (HE) models is being used more commonly in health technology assessment (HTA) in the US, it is not consistently adopted by different stakeholder groups or across therapeutic areas. We hypothesize that actively engaging with multiple stakeholder groups throughout the model development process may result in models more widely considered by decision makers. To test this hypothesis, the Innovation and Value Initiative has launched a modeling effort to build an open-source HE model focusing on the disease state 'major depressive disorder'. Read More

Analysis of paralogs in target enrichment data pinpoints multiple ancient polyploidy events in Alchemilla s.l. (Rosaceae).

Syst Biol 2021 May 12. Epub 2021 May 12.

Department of Plant and Microbial Biology, University of Minnesota-Twin Cities, 1445 Gortner Avenue, St. Paul, MN 55108, USA.

Target enrichment is becoming increasingly popular for phylogenomic studies. Although baits for enrichment are typically designed to target single-copy genes, paralogs are often recovered with increased sequencing depth, sometimes from a significant proportion of loci, especially in groups experiencing whole-genome duplication (WGD) events. Common approaches for processing paralogs in target enrichment data sets include random selection, manual pruning, and mainly, the removal of entire genes that show any evidence of paralogy.

Antagonistic selection on body size and sword length in a wild population of the swordtail fish, : Potential for intralocus tactical conflict.

Ecol Evol 2021 May 20;11(9):3941-3955. Epub 2021 Mar 20.

Instituto de Ecología AC Red de Biología Evolutiva Xalapa, Veracruz México.

Alternative reproductive tactics (ARTs) have provided valuable insights into how sexual selection and life history trade-offs can lead to variation within a sex. However, the possibility that tactics may constrain evolution through intralocus tactical conflict (IATC) is rarely considered. In addition, when IATC has been considered, the focus has often been on the genetic correlations between the ARTs, while evidence that the ARTs have different optima for associated traits and that at least one of the tactics is not at its optimum is often missing.

Beyond cognitive templates: re-examining template metaphors used for animal recognition and navigation.

Integr Comp Biol 2021 May 10. Epub 2021 May 10.

Department of Biological Sciences, University of Cincinnati.

The term 'cognitive template' originated from work in human-based cognitive science to describe a literal, stored, neural representation used in recognition tasks. As the study of cognition has expanded to non-human animals, the term has diffused to describe a wider range of animal cognitive tools and strategies that guide action through the recognition of and discrimination between external states. One potential reason for this non-standardized meaning and variable employment is that researchers interested in the broad range of animal recognition tasks enjoy the simplicity of the cognitive template concept and have allowed it to become shorthand for many dissimilar or unknown neural processes without deep scrutiny of how this metaphor might comport with underlying neurophysiology.
