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.

Using the Lonsdorf model for estimating habitat loss and fragmentation effects on pollination service (open access)

Using the Lonsdorf model for estimating habitat loss and fragmentation effects on pollination service

Article examining the effects of habitat loss and fragmentation on pollination separately according to the Lonsdorf model. Results show that the effects of habitat loss and fragmentation on pollination are completely different at the landscape and farm levels. This article shows that using the Lonsdorf model could lead to confusing results for the landscape ecologists and farmers who want to reduce the adverse effects of fragmentation on their products by creating new forest patches.

The Gendered Consequences of a Weak Infrastructure of Care: School Reopening Plans and Parents’ Employment During the COVID-19 Pandemic (open access)

The Gendered Consequences of a Weak Infrastructure of Care: School Reopening Plans and Parents’ Employment During the COVID-19 Pandemic

This article collected detailed primary data—the Elementary School Operating Status database (ESOS)—to measure the percentage of school districts offering in-person, remote, and hybrid instruction models for elementary schools by state in September 2020 to understand the nature and magnitude of school closures across states during the COVID-19 pandemic and its effect on maternal labor force participation. The article shows that schools are a vital source of care for young children, and that without in-person instruction, mothers have been sidelined from the labor force.

The Perils of Complexity: A multi-stage study to determine necessary images for digitized scrapbook representation

Presentation on a multi-stage study to assess national trends and user preferences for scrapbook representation undertaken by librarians at the University of North Texas. The stages of this study included a review of national trends in scrapbook digitization, as seen in the Digital Public Library of America; a paper-prototyping-inspired, in-person user study; and an online survey of user preferences. The results of this research have enabled the implementation of clear guidelines at the University of North Texas for scrapbook digitization that accounts for the user experience rather than strictly relying on personal opinion or local librarian consensus. It was presented at the Visual Resource Association Annual Conference held on March 22-26, 2021.

This article uses agent-based simulations in three “artificial societies” (one predominantly religious; one predominantly secular; and one in between), to demonstrate that worldview pluralism within one’s neighborhood and family social networks can be a significant predictor of religious (dis)affiliation but in pluralistic societies worldview diversity is less important and, instead, people move toward worldview neutrality.
