The Politics of School Reopening During COVID-19: A Multiple Case Study of Five Urban Districts in the 2020-21 School Year.

Purpose: Nearly all schools in the United States closed in spring 2020, at the onset of the COVID-19 pandemic. We analyze traditional public and charter school reopenings for the 2020-21 school year in five urban districts. We provide a rich and theoretically grounded description of how and why educational leaders made reopening decisions in each of our case districts. Research Methods: We used data from a multiple-case study from March 2020 to July 2021. The research team conducted 56 interviews with school, district, and system-level leaders; triangulated with publicly available data; and also drew on interview data from a subsample of parents and guardians in each of our sites. We analyzed these data through qualitative coding and memo writing and conducted detailed single- and cross-case analyses. Findings: School system leaders in our case sites generally consulted public health authorities, accounted for state-level health and educational guidance, and engaged with and were responsive to the interests of different stakeholders. Districts' adherence to and strategic uses of public health guidance, as well as a combination of union-district relations and labor market dynamics, influenced reopening. Parents, city, and state lawmakers, and local institutional conditions also played a role, helping to explain differences across cases. Implications: In contrast to the "politics or science" framing that has dominated research and public discourse on school reopening, we show that local pandemic conditions and local political dynamics both mattered and in fact were interrelated. Our findings have some implications for how educational leaders might navigate future crises.

Social Construction Is Racial Construction: Examining the Target Populations in School-Choice Policies.

Purpose: We examine policy influencers' perceptions of the targets of school-choice policy across five states, exploring how constructions varied for White and racially minoritized families, whether policy actors conceived of the "target" of policy as the child or the parent, and how these racialized constructions varied across different types of school-choice policies. Research Methods/Approach: We conducted 56 semistructured interviews in 2019 with state-level stakeholders across five states. Findings: We found that policy actors generally viewed White families as strong and racially minoritized families as weak. However, for both groups, we found variation in whether these constructions were positive or negative and differences between students and parents. We find that social constructions are fluid, with varying, sometimes conflicting and contradictory views of racially minoritized and White parents in the same period, within the same state context. Despite the salience of race throughout social constructions of the target population, policy actors primarily used color-evasive references. In general, we found little variation in policy components at the state level. Implications: Our work demonstrates how racialized social constructions matter for equity in school-choice policy, with implications for local, state, and federal policy and for future research.

Ancestry-inclusive dog genomics challenges popular breed stereotypes.

Behavioral genetics in dogs has focused on modern breeds, which are isolated subgroups with distinctive physical and, purportedly, behavioral characteristics. We interrogated breed stereotypes by surveying owners of 18,385 purebred and mixed-breed dogs and genotyping 2155 dogs. Most behavioral traits are heritable [heritability (h2) > 25%], and admixture patterns in mixed-breed dogs reveal breed propensities. Breed explains just 9% of behavioral variation in individuals. Genome-wide association analyses identify 11 loci that are significantly associated with behavior, and characteristic breed behaviors exhibit genetic complexity. Behavioral loci are not unusually differentiated in breeds, but breed propensities align, albeit weakly, with ancestral function. We propose that behaviors perceived as characteristic of modern breeds derive from thousands of years of polygenic adaptation that predates breed formation, with modern breeds distinguished primarily by aesthetic traits.

BarkBase: Epigenomic Annotation of Canine Genomes.

Dogs are an unparalleled natural model for investigating the genetics of health and disease, particularly for complex diseases like cancer. Comprehensive genomic annotation of regulatory elements active in healthy canine tissues is crucial both for identifying candidate causal variants and for designing functional studies needed to translate genetic associations into disease insight. Currently, canine geneticists rely primarily on annotations of the human or mouse genome that have been remapped to dog, an approach that misses dog-specific features. Here, we describe BarkBase, a canine epigenomic resource available at barkbase.org. BarkBase hosts data for 27 adult tissue types, with biological replicates, and for one sample of up to five tissues sampled at each of four carefully staged embryonic time points. RNA sequencing is complemented with whole genome sequencing and with assay for transposase-accessible chromatin using sequencing (ATAC-seq), which identifies open chromatin regions. By including replicates, we can more confidently discern tissue-specific transcripts and assess differential gene expression between tissues and timepoints. By offering data in easy-to-use file formats, through a visual browser modeled on similar genomic resources for human, BarkBase introduces a powerful new resource to support comparative studies in dogs and humans.
