Strategies for Increasing Findabilitiy of Language Data

Poster discussing practical methods for ensuring the quality of descriptive metadata associated with linguistic datasets in language archive deposits. Digital language archives are valuable tools for facilitating language revitalization, providing data on lesser-known languages, and supporting reproducibility of research and development of linguistic theory, though their potential remains unrealized as the data available in language archives are rarely accessed by linguists or language communities. Reasons for this under-utilization are the issues with data standardization and metadata quality. Including basic grammatical and typological information would allow wider audiences to reach the material.

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds (open access)

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds

This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses (open access)

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses

Describes study which assessed the upper (CTmax) and lower (CTmin) thermal limits of three freshwater macroinvertebrate taxa with restricted low elevation distribution (20 m a.s.l.) and three taxa restricted to upper elevations (480 and 700 m a.s.l.) in the Magellanic sub-Antarctic ecoregion of southern Chile, and argues that their low tolerance to temperature increase can make them useful as indicators of thermal alteration in their habitats.

TS: A powerful truncated test to detect novel disease associated genes using publicly available gWAS summary data

This article proposes a new truncated statistic method (TS) by utilizing a truncated method to find the genes that have a true contribution to the genetic association. The proposed truncated statistic outperforms existing methods. It can be employed to detect novel traits associated genes using GWAS summary data.

Leaf Lipid Alterations in Response to Heat Stress of Arabidopsis thaliana (open access)

Leaf Lipid Alterations in Response to Heat Stress of Arabidopsis thaliana

Article measuring lipid levels with mass spectrometry to confirm the previously observed changes in Arabidopsis thaliana leaf lipids under three heat stress regimens. Additionally, in response to heat, increased oxidation of the fatty acyl chains of leaf galactolipids, sulfoquinovosyldiacylglycerols, and phosphatidylglycerols, and incorporation of oxidized acyl chains into acylated monogalactosyldiacylglycerols are shown. The authors also observed increased levels of digalactosylmonoacylglycerols and monogalactosylmonoacylglycerols. The hypothesis that a defect in sterol glycosylation would adversely affect regrowth of plants after a severe heat stress regimen was tested, but differences between wild-type and sterol glycosylation-defective plants were not detected.

Chemical and Genetic Studies on the Formation of Pyrrolones During the Biosynthesis of Cytochalasans (open access)

Chemical and Genetic Studies on the Formation of Pyrrolones During the Biosynthesis of Cytochalasans

This article investigates the role of the highly conserved α,β-hydrolase enzymes PyiE and ORFZ during the biosynthesis of pyrichalasin H and the ACE1 metabolite, respectively, using gene knockout and complementation techniques. Taken together the results suggest that the α,β-hydrolase enzymes are essential for first ring cyclisation, but the precise nature of the intermediates remains to be determined.

Initial Response to COVID-19: A Mixed-Methods Analysis of Media and School Communications to Identify Pedagogical Implications for Remote Teaching (open access)

Initial Response to COVID-19: A Mixed-Methods Analysis of Media and School Communications to Identify Pedagogical Implications for Remote Teaching

Article examining one month of social media, news media, school district websites’ continuity plans and educational affiliate organizations, to unveil K-12 stakeholders’ initial response to K-12 remote teaching following the declaration of the national emergency of the COVID-19 pandemic in the USA. Initial responses focused on community lockdown procedures, sustaining education, adapting to a remote lifestyle and political tension. The authors revisited included tweets one week later to measure their connectedness, which revealed that educational organizations, which have the largest number of followers, also have the greatest outreach and visibility. This is the accepted manuscript of the article which has been approved to post in an institutional repository.

Are States Created Equal? Moving to a State With More Expensive Childcare Reduces Mothers' Odds of Employment

This article investigates whether moving to a state with more expensive childcare is associated with lower odds of maternal employment among mothers who had been employed prior to relocation. Results show that moving to states with fewer childcare barriers is associated with higher levels of maternal employment, partly mitigating the negative labor market effects of interstate migration.
