Air Pressure Propagation Through Wind Cave And Jewel Cave: How Do Pressure Waves Travel Through Barometric Caves?, Annika K. Gomell, Daniel C. Austin, Marc J. Ohms, Andreas Pflitsch

International Journal of Speleology

In barometric caves, air pressure gradients between the outside atmosphere and the cave induce strong bidirectional compensating currents, which control almost all elements of speleoclimatology, including air temperature, humidity, and CO2 dynamics. Therefore, this study set out to investigate air pressure propagation through Wind Cave and Jewel Cave – two major barometric cave systems in the Black Hills of South Dakota, USA. Based on high-resolution air pressure data from both the surface and several measurement sites inside the caves, four systematic changes of pressure waves during their journey through the caves and their related speleoclimatological processes were identified and …

If You Are Not Ready, Then Step Aside: Intentionally Centering The Black Male Body In Teacher Education, Cherrel Miller Dyce, Julius Davis Sep 2021

If You Are Not Ready, Then Step Aside: Intentionally Centering The Black Male Body In Teacher Education, Cherrel Miller Dyce, Julius Davis

Northwest Journal of Teacher Education

The conditions of Black male students in K-12 schools have been well-documented by scholars and clearly illustrate institutionalized anti-Black maleness that continues to go unaddressed or, in some cases, never addressed in most educator preparation programs and school systems in the U.S. We call for the centering of Black male bodies in teacher education and offer Afrocentric Assessment Mattering Pathways (AAMP) for guidance for intentionally centering the Black male body in teacher education: 1) critical anti-black self-reflection, 2) Afrocentric curricular change using Black history, and 3) engaging in off-campus Afrocentric environments.


Forest Fire Effects On The Temporal Variability Of Landscape Snow Albedo Relative To Burn Severity, Max Gersh Sep 2021

Forest Fire Effects On The Temporal Variability Of Landscape Snow Albedo Relative To Burn Severity, Max Gersh

Dissertations and Theses

Snow-water storage is decreasing, while forest fires are increasing in duration, size, frequency, and intensity, due to climate change. Most forest fires occur in the seasonal snow zone, altering snow mass and energy balance for many years following fire. Following forest fires, Surface snow albedo (SSA) decreases, as light absorbing particles (LAP), particularly black carbon (BC) produced in forest fires get deposited throughout the snowpack, altering snowpack energy balance driving earlier snowmelt in burned forests. While SSA decreases, landscape snow albedo (LSA) increases following fire, as more of the snow-covered surface becomes visible beneath the burned forest canopy, brightening the …

Emergency Medicine And Covid-19: Now And Next Year, Theodore A. Christopher, Adrienne N. Christopher

Department of Emergency Medicine Faculty Papers

The COVID-19 pandemic is responsible for infecting to date more than 93 million people worldwide and causing more than 2 million deaths. That the vast majority of deaths have occurred in the United States (U.S.) can be attributed to nonadherence by Americans to basic public health mitigation strategies that are known to curtail coronavirus spread. Emergency Departments (ED’s) throughout the U.S. experienced a dramatic decrease in patient visits during the first surge of COVID-19, followed by an ED patient visit rebound to approximately 80% of pre-COVID-19 numbers, which have remained relatively stable through the current second COVID-19 surge.

Growth–Defense Trade-Offs Shape Population Genetic Composition In An Iconic Forest Tree Species, Olivia L. Cope, Ken Keefover-Ring, Eric L. Kruger, Richard L. Lindroth Sep 2021

Growth–Defense Trade-Offs Shape Population Genetic Composition In An Iconic Forest Tree Species, Olivia L. Cope, Ken Keefover-Ring, Eric L. Kruger, Richard L. Lindroth

Aspen Bibliography

All organisms experience fundamental conflicts between divergent metabolic processes. In plants, a pivotal conflict occurs between allocation to growth, which accelerates resource acquisition, and to defense, which protects existing tissue against herbivory. Trade-offs between growth and defense traits are not universally observed, and a central prediction of plant evolutionary ecology is that context-dependence of these trade-offs contributes to the maintenance of intraspecific variation in defense [Züst and Agrawal, Annu. Rev. Plant Biol., 68, 513–534 (2017)]. This prediction has rarely been tested, however, and the evolutionary consequences of growth–defense trade-offs in different environments are poorly understood, especially in long-lived species …
