Visualization is a powerful tool to help people better communicate and understand data. But the perception and interpretation of data is riddled with bias. Data visualizations are ambiguous objects such that different people viewing the same visualization can come to different conclusions. The ambiguity is likely associated with people's perceptual...
This dissertation observes interaction to explore the influence of group argument in decision-making in mock juries. The goals of this investigation were to observe two-sided deliberations of a task-oriented decision-making group, map the dichotomous arguments and provide insight into what influences were at play in the final decision. The study...
This dissertation is a collection of three papers on synthesizing and translating statistical evidence in education research. Chapter 1 serves as an introduction and executive summary, and Chapters 2 - 4 contain the three substantive papers respectively. Chapter 2 presents methods for pooling sample variances across studies to improve properties...
Equilibrium models of star formation successfully derive the globally-averaged Kennicutt-Schmidt (KS) relation, positing that star formation rates (SFRs) are self- regulated by the turbulence in the interstellar medium (ISM) generated by stellar feedback. However, these models make assumptions that may not be achieved in realistic galaxy systems. Cosmological zoom-in simulations,...
MANUSCRIPT ABSTRACT:
The analysis of citations to scientific publications has become a tool in the evaluation of a researcher’s work, especially due to an ever-increasing production volume. Despite its acknowledged shortcomings and the ongoing debate on their meaning, citations are still primarily viewed as endorsements and as indicators of the...
Bumble bees are ecologically and economically important pollinators but have experienced rapid declines in recent decades. Yet, we know little about the lives of most wild bumble bee species. Where do they live? When are they active? What do they eat? What does all this mean for the future of...
As of March 28, 2021, the CDC's COVID-19 Vaccination Data shows the following: 1. Alaska, New Mexico, and South Dakota are leading the nation in vaccinating their populations. 2. The most populous states receive the greatest number of vaccines (ex: California). 3. The most populous states are not the most...
American communities of color have shouldered a disproportionate share of the COVID-19 pandemic’s burden. For instance, at peak, Hispanic/Latino Americans experienced a weekly all-cause death burden 130.9% in excess of previous years. Not all excess deaths are directly attributable to COVID-19—there is emerging evidence that delays in care associated with...
My submission is a data dashboard that depicts global trends for new and total COVID-19 cases between Jan 01, 2020 and March 08, 2021. It contains two tabs (new and total cases) with three interactive visualizations. Two maps, an original and a log-scale-filled, show the number of new COVID-19 cases...
Astronomers are studying how young stellar objects (YSOs) develop and accrete mass. The variability of the YSO brightness can give information about the rate of accretion and the growth of these young stars. The YSOs described in this project are found in the Large Magellanic Cloud, a galaxy nearby to...
