Background: Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical...
Background: Parental characteristics that influence child physical activity (PA) behavior often co-occur. An analytic approach that considers these co-occurring patterns can help researchers better understand the overall context of parental influence. The study aims were to: (1) identify diverse patterns of the relationships among parental characteristics, (2) examine the influence...
Presented at the University of Western Ontario's "Digital Humanities Speaker Series" on October 16, 2013. An earlier version was presented at the Illinois Institute of Technology's "Digital Humanities Speaker Series" on September 11, 2013. Many thanks to Whitney Trettien, Heather Froehlich, David Golumbia, and Robin Camille Davis for reading and...
The following short talk—an initial thinking-through and provocation from my recent reading—was presented at HASTAC 2014 in Lima, Peru, as part of the “Political Platforms: Software, Social Justice, and Designing for Change” panel, which included Beatrice Choi, Anne Cong-Huyen, Amanda Philips, and Tara McPherson (discussant).
This short talk was a part of a panel, "Digital Literacy in the Classroom," organized by Ann Hanlon and Abigail Nye (University of Wisconsin-Milwaukee), and which included Harriett Green (University of Illinois Urbana Champaign), and myself, at the 2016 DLF Forum in Milwaukee, WI, on November 8, 2016.
Artificial spin ice lattices have emerged as model systems for studying magnetic frustration in recent years. Most work to date has looked at periodic artificial spin ice lattices. In this paper, we observe frustration effects in quasicrystal artificial spin ice lattices that lack translational symmetry and contain vertices with different...
We report on a diffusive analysis of the motion of flagellate protozoa species. These parasites are the etiological agents of neglected tropical diseases: leishmaniasis caused by Leishmania amazonensis and Leishmania braziliensis, African sleeping sickness caused by Trypanosoma brucei, and Chagas disease caused by Trypanosoma cruzi. By tracking the positions of...
The R package COPASutils provides a logical workflow for the reading, processing, and visualization of data obtained from the Union Biometrica Complex Object Parametric Analyzer and Sorter (COPAS) or the BioSorter large-particle flow cytometers. Data obtained from these powerful experimental platforms can be unwieldy, leading to difficulties in the ability...
Over the course of tumor growth, cancer cells interact with normal cells via processes that are difficult to understand by experiment alone. This challenge is particularly pronounced at early stages of tumor formation, when experimental observation is most limited. Eluci-dating such interactions could inform both understanding of cancer and clinical... and Tumor growth involves a dynamic interplay between cancer cells and host cells, which col-lectively form a tumor microenvironmental network that either suppresses or promotes tumor growth under different conditions. The transition from tumor suppression to tumor pro-motion is mediated by a tumor-induced shift in the local immune state, and despite...
