    Antiracist study group policies and practices
    (2022) Arendale, David R
    My talk had six sections: (a) the influence of campus culture on student persistence, (b) antiracism resources for peer study group programs, (c) selected definitions related to antiracism, (d) highlights from the guide for Course-based Learning Assistance, (e) sample of antiracism policies and practices, and (f) additional resources for peer study group programs. I shared this talk at one of the monthly professional development seminars for the peer study group leaders at the University of Texas at San Marcos.

    Data and visualizations of air quality impacts of conventional and alternative light-duty transportation in the United States
    (2014-11-25) Tessum, Christopher W; Hill, Jason D; Marshall, Julian D; julian@umn.edu; Marshall, Julian D.
    This is the supporting information for an article entitled "Life cycle air quality impacts of conventional and alternative light-duty transportation in the United States", published in the Proceedings of the National Academy of Sciences of the United States (dx.doi.org/10.1073/pnas.1406853111). The study assesses the life cycle air quality impacts on human health of 10 alternatives to conventional gasoline vehicles, including vehicles powered by diesel, natural gas, ethanol, and electricity. This supporting information is comprised of 1) A Microsoft Excel file containing emissions amounts disaggregated by life cycle stage for each scenario; 2) maps of ground-level concentrations of 13 different air pollutants attributable to each scenario; and 3) videos showing temporal variation in ground-level fine particulate matter (PM2.5) and ozone (O3) concentrations attributable to each scenario. The data here were generated using state-of-the-science air pollutant emission and transport models.

    Moving forward with diversity, equity, and inclusion: Changing the culture of postsecondary education
    (2022) Arendale, David R
    My talk had six sections: (a) definitions of diversity, equity, and inclusion; (b) sample DEI statements; (c) what we know about campus culture; (d) definitions of key antiracism terms; (e) antiracist behaviors and policies for learning assistance; and (f) additional resources for DEI, peer learning programs, and other learning assistance activities. I shared this talk at the annual conference of the New York College Learning Skills Association. NYCLSA is focused on best practices for developmental-level courses, peer study programs, tutoring, and learning centers. This profession has already been making significant changes to implement antiracist practices.

    Sample 360 video for the analysis of plant movement
    (2018-09-12) Susko, Alexander, Q; susko004@umn.edu; Susko, Alexander, Q; University of Minnesota Oat Breeding and Genetics Lab
    Violent movement of cereal crop stems can lead to failure under high winds. Known as lodging, this phenomenon is particularly severe in cereal crops such as oat, barley, and wheat, and contributes to yield and economic losses. Quantifying the movement of cereal crops under field wind stress could aid in the breeding and selecting of lodging resistant cereals. We present a method to quantify the wave like movement of cereal crop rows in a high throughput fashion under field wind conditions. By analyzing pre-defined regions of hemispherical 4K resolution video, we obtain a time varying color signal of wind induced stem and canopy movement. Bandpass filtering is applied to the color signals to filter out changes in lighting due to sunlight changes, enabling comparisons across different lighting conditions. Peaks are then identified in the signal, and the distance in frames to the next peak as well as the absolute area under the curve between peaks is recorded. The distributions of distances to adjacent peaks (expressed as frequencies) are recorded and the area within a defined frequency bin is summed to get an approximation of the frequency and amount movement. We applied this method to analyze the wind induced movement of 16 cereal cultivars planted in a randomized complete block design on 5 different windy days. We detected significant differences in the mean frequency and amplitude within 0.2 Hz frequency bins among 16 cereal cultivars, with mean frequencies ranging between 1.24 and 1.53 Hz. This method quantifies the frequency and amplitude of movement in cereal varieties at high throughput in the field, and shows promise for characterizing the physiological basis for differences in cereal movement and lodging resistance.

    Usingl podcasting for education: Anywhere, anytime
    (2022) Arendale, David R.
    These are the topics: (a) podcasting described and why popular, (b) lessons and statistics about podcasting, (c) distributing podcasts widely, (d) how to begin podcasting (develop the podcast idea, recording software and hardware, selecting the podcast host, find a partner for the technical part of podcasting), (e) creating voice from text-to-voice software, (f) creating audiobooks, and (g) suggested next steps in the podcasting process. I shared this talk for the United Kingdom Academic Peer Learning Community with a focus on podcasting. I have been podcasting since 2005 as a companion to my global history course and also with other topics of my interest. It was a fast-moving talk and demonstration.
