Layered Sites of Environmental Justice: Considering the Case of Prisons*
Sociological Inquiry, Volume 93, Issue 4, Page 852-876, November 2023., 2023 A growing body of scholarship highlights the merits of fusing green criminology and environmental justice frameworks to better understand intersections among carceral systems, race‐ and class‐based stratification, and environmental harm. This paper explores how correctional institutions (CIs) with known histories of federal environmental law violations

The Effect of Spacing Versus Massing on Orthographic Learning
Reading Research Quarterly, Volume 58, Issue 3, Page 361-372, July/August/September 2023., 2023 Abstract Distributing study opportunities over time typically improves the retention of verbal material compared to consecutive study trials, yet little is known about the influence of temporal spacing on orthographic form learning specifically. This experiment sought to obtain and compare estimates of the magnitude of the spacing effect on written ...

The slow and steady salinization of Sparkling Lake, Wisconsin
Limnology and Oceanography Letters, Volume 8, Issue 1, Page 74-82, February 2023., 2023 The concentrations of conservative solutes in seepage lakes are determined by the relative inputs of precipitation vs. groundwater. In areas of road salt application, seepage lakes may be at high risk of salinization depending on groundwater flow. Here, we revisit a 1992 analysis on the salinization of Sparkling Lake, a deep seepage lake in Northern ...

Variability in fluvially‐dominated, fine‐grained, shallow‐water deltas
Sedimentology, Volume 69, Issue 7, Page 2779-2813, December 2022., 2022 Abstract Fluvially‐dominated, fine‐grained, shallow‐water deltas are more variable than is generally recognized. Studies of the Mississippi River imply rather persistent river‐mouth jet dynamics, resulting in either progressive channel bifurcation around middle‐ground mouth bars on lobate deltas, or steady channel progradation to form elongate deltas ...

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022 We documented and examined patterns of species richness and abundance of tropical epiphytes along the entire elevational gradient of an isolated, island volcano. Our complete and detailed sampling along the gradient improves our understanding of vascular epiphyte distribution and its association to weather variables, based on direct observations.
