Loren Haarsma - When Did Sin Begin?, Loren Haarsma

University Faculty Publications and Creative Works

Patrick Hamilton speaks to Calvin University Professor, Loren Haarsma, about the origins of sin and various ways to make sense of the doctrine of original sin in light of evolutionary origins. Other topics of conversation include psychology, free will and the theology of Saint Augustine.

Data From: Yellow Air Day Advisory Study, Arthur J. Caplan

Browse all Datasets

Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the lower atmosphere, leading to unhealthy air quality (concentrations of at least 35 µg/m3) over a span of what are called “red air days”. When concentrations …

Reeling In New Antibiotics: Synthesis And Antimicrobial Susceptibility Testing Of Zinc-Binding Clavanins From Styela Clava (Sea Squirt), Eduardo Badillo-Colberg

Honors Scholar Theses

Clavanins have been a quite rarely studied antimicrobial peptide (AMP) family. Though the data in the few studies published on the matter and in theoretical experimental data presented by the Wang lab in their peptide library creation [14], in that the members of this family could potentially be quite effective novel antimicrobial candidates. Among those that have been targets of studies, Clavanin A has been at the forefront of this endeavor of finding effective novel antimicrobial peptides[14]. In these aforementioned studies, Clavanin A has been shown to be quite effective against many different bacterial strains, which begs the question as …

Accessibility: Disabilities Treasure Hunt, Devorah Kletenik

Open Educational Resources

This is a treasure hunt game that simulates various disabilities and gives a sense of how frustrating non-accessible content can be for people with disabilities. Suitable for a general audience, no programming experience necessary.

An editable copy is also given, along with ideas about how to make it more accessible.

Supporting Data - Recycling Of Nitrate And Organic Matter By Plants In The Vadose Zone Of A Saturated Riparian Buffer, Patience Bosompemaa, Eric Wade Peterson, William Perry, Wondwosen M. Seyoum

Faculty Publications-- Geography, Geology, and the Environment

Data from the analysis of nitrate as nitrogen in the soil and soil pore water within the vadose zone of a saturated riparian buffer (SRB). Additional properties measured include: Organic matter (as %), bulk density, moisture content, and porosity. Soil samples were collected pre-growing season (n=57) and post-growing season from two plots (n=29): vegetated plots and barren plots. Statistical comparison of among the treatments, Pre-growing season, plot with plants, and barren plot, and among the different depths, 30 cm, 60 cm, and 90 cm identified significantly different soil NO₃^--N concentrations. Plots with plants experienced a reduction in …

Sars-Cov-2 Exposure In Wild White-Tailed Deer (Odocoileus Virginianus), Jeffrey C. Chandler, Sarah N. Bevins, Jeremy W. Ellis, Timothy J. Linder, Rachel M. Tell, Melinda Jenkins-Moore, J.

USDA Wildlife Services: Staff Publications

Widespread human SARS-CoV-2 infections combined with human–wildlife interactions create the potential for reverse zoonosis from humans to wildlife. We targeted white-tailed deer (Odocoileus virginianus) for serosurveillance based on evidence these deer have angiotensin-converting enzyme 2 receptors with high affinity for SARS-CoV-2, are permissive to infection, exhibit sustained viral shedding, can transmit to conspecifics, exhibit social behavior, and can be abundant near urban centers. We evaluated 624 prepandemic and postpandemic serum samples from wild deer from four US states for SARS-CoV-2 exposure. Antibodies were detected in 152 samples (40%) from 2021 using a surrogate virus neutralization test. A subset of samples …

Compiled Dataset From The National Reservoir Research Program 1989 Dataset, Nicky M. Faucheux, Leandro E. Miranda

College of Forest Resources Publications and Scholarship

This dataset was compiled from the National Reservoir Research Program 1989 dataset. The NRRP dataset includes data from rotenone and creel studies at reservoirs throughout the continental US during the 1980s. We compiled the species level biomass data into total biomass for each of five trophic guilds (piscivores, detritivores, herbivores, invertivores, and planktivores). This compiled dataset was used to investigate the Cascading Reservoir Continuum Concept across 16 river basins in a study conducted by the 2020 Management of Impounded Rivers Class.
