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.

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.

Bioresorbable stent to manage congenital heart defects in children (open access)

Bioresorbable stent to manage congenital heart defects in children

This article assembles large, pediatric-sized stents (Ø10 - Ø20 mm) from poly(L-lactide) fibers (DH-BDS) at two thicknesses, 250 µm and 300 µm. DH-BDS exhibiting hoop strength similar to metal stents and demonstrating minimal degradation and strength loss over the first year before completely disappearing within 3 to 4.5 years show promise as a pediatric interventional alternative to current strategies.

Anti-racist Praxis at Futurist Art and Design Pedagogy captions transcript

Anti-racist Praxis at Futurist Art and Design Pedagogy

Video recording featuring esteemed guest panelists, Tameka Ellington, Ph.D., Cheryl D. Holmes Miller, and Terresa Moses, M.F.A., this second installment of the 2044 series highlights the ways that working against anti-Blackness through the lens of Afrofuturism and Critical Race Theory allows for the examination and enactment of decolonizing design bias and white default. This session brings questions of Black agency, stereotyping, bias, representation, appropriation, commodification, and the dangers of pathologizing Blackness in design. Panelists discuss anti-racist practice in design education through forms of resistance and resilience.

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.

Religious Exiting and Social Networks: Computer Simulations of Religious/Secular Pluralism (open access)

Religious Exiting and Social Networks: Computer Simulations of Religious/Secular Pluralism

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.
