1. Co-Authorship Maps to Support Leadership Selection

   https://doi.org/10.13023/VG16-XQ81  

   Chen, Robert HC (April 2024, University of Kentucky Libraries)

   VOSViewer co-authorship mapping is a powerful tool typically used for analyzing research collaboration. Users provide publication data and VOSViewer produces a map where authors are plotted on a 2-dimensional map based on how often they are in the author lists of the same publication. In this presentation, I propose a series of tweaks to the input data that can leverage co-authorship maps to support leadership selection based on how often candidates co-author papers with their institutional peers and some of the attributes of these papers. I will suggest how best to interpret the resulting maps and address the major assumptions that must be kept in mind when using these maps for this purpose. Lastly, I will discuss the lessons learned when we offered such maps to support a series of internal leadership selections for Canada’s largest research hospital.

2. Spherical conical metrics and harmonic maps to spheres

   https://doi.org/10.1090/tran/8578  

   Karpukhin, Mikhail; Zhu, Xuwen (February 2022, Transactions of the American Mathematical Society)

   A spherical conical metric g g on a surface Σ \Sigma is a metric of constant curvature 1 1 with finitely many isolated conical singularities. The uniformization problem for such metrics remains largely open when at least one of the cone angles exceeds 2 π 2\pi . The eigenfunctions of the Friedrichs Laplacian Δ g \Delta _g with eigenvalue λ = 2 \lambda =2 play a special role in this problem, as they represent local obstructions to deformations of the metric g g in the class of spherical conical metrics. In the present paper we apply the theory of multivalued harmonic maps to spheres to the question of existence of such eigenfunctions. In the first part we establish a new criterion for the existence of 2 2 -eigenfunctions, given in terms of a certain meromorphic data on Σ \Sigma . As an application we give a description of all 2 2 -eigenfunctions for metrics on the sphere with at most three conical singularities. The second part is an algebraic construction of metrics with large number of 2 2 -eigenfunctions via the deformation of multivalued harmonic maps. We provide new explicit examples of metrics with many 2 2 -eigenfunctions via both approaches, and describe the general algorithm to find metrics with arbitrarily large number of 2 2 -eigenfunctions.

   Ascher, Kenneth; Bejleri, Dori (February 2023, Épijournal de Géométrie Algébrique)

   Using log geometry, we study smoothability of genus zero twisted stable mapsto stacky curves relative to a collection of marked points. One application isto smoothing semi-log canonical fibered surfaces with marked singular fibers.

5. Using Circuit Playground and Maps To Visualize Migration Data

   Cannell, Christa; Tofel-Grehl, Colby; Searle, Kristin; Hawkman, Andrea (January 2020, International Conference of the Learning Sciences)

   Gresalfi, Melissa; Horn, I. S. (Ed.)

   This paper shares the design and process of development for a data visualization project that centers computing squarely in social studies classroom instruction for social justice. Circuit Playground Expresses are programmed to engage students in engaging with and creating visualizations of the Great Migration of Black folx from the American South during the Jim Crow era.
