New article! Where are GIScience faculty hired from? Yanbing Chen and colleagues, using data from GISphere, analyze faculty mobility and research themes through hiring networks #GISchat doi.org/10.1080/1523... Below: where current GIS faculty are (x-axis) and where they got their PhDs (y-axis).
Figure 7. Marimekko chart visualizing the distribution of GIS faculty placements across four continents (North America, Asia, Europe, and Oceania) and their PhD origins. The X-axis represents the total number of current GIS faculty in each continent, while the Y-axis shows the percentage of faculty based on where they obtained their Ph.Ds. The width of each segment on the X-axis corresponds to the number of GIS faculty in that continent, and the colored segments represent the proportion of faculty whose PhD origins are from different continents. For example, a total of 345 GIS faculty members are currently affiliated with institutions in North America. Of these, 89.0% obtained their PhDs in North America, 7.8% in Europe, 2.0% in Asia, 0.9% in Oceania, and 0.3% in Africa.

New article! Darlan Miranda Nunes & Silvana Philippi Camboim investigate Collaborative toponyms in OpenStreetMap evaluating the potential to complement and update National Mapping Agencies data, doi.org/10.1080/1523... also see their code and process at github.com/darlanmnunes...
#GISchat
A grid of six choropleth maps comparing OpenStreetMap toponym coverage across two Brazilian cities (Água Verde in Paraná and Passaré in Ceará) and three data categories (Leisure, Building, and Amenity). Each map uses equal interval classification showing the proportion of OSM toponyms in grid cells, with a legend indicating: 0-25% (cream/white), 25-50% (light green), 50-75% (medium green), and 75-100% (dark green). Água Verde shows more dispersed coverage with darker concentrations in the top row (Leisure) and bottom row (Amenity), while Passaré shows sparser overall coverage with notable clustering in the Amenity category. The Building row shows minimal to no coverage for both cities, appearing almost entirely cream-colored. Figure 5 caption reads: 'Choropleth maps based on the equal interval classification of OSM toponyms by tag in the study areas.'

New paper! Fascinating discussion of Optimizing electric vehicle supply equipment allocation using a range of local and global MCDA methods by Emily Zhou & Junyi Yang, #GISchat doi.org/10.1080/1523...
Figure showing four neighborhood clusters in Philadelphia derived from spectral clustering. Panel a displays a map with colored squares representing four clusters: Cluster 1 (dark blue) concentrated in center city and some northern areas, Cluster 2 (olive green) in northwest sections, Cluster 3 (light green) in northeast regions, and Cluster 4 (teal) spanning south and southwest Philadelphia. Panels b)-d) show density distribution curves for each cluster: panel b) shows driving age population with two peaks, panel c) displays EV registration levels with multiple peaks at lower values, and panel d) illustrates distance to nearest electric vehicle supply equipment (EVSE) with highest density at shorter distances tapering off toward 1.00.

I feel like stuff like this is too often overlooked in discussions around technology-based mitigations of climate change. If we use tech innovations to make it easy and convenient for people to use the “greener” alternative that already exists, they’ll use it.

Living in the Future benefit: the combination of Google Maps public transit directions and phone-tap onboard payment makes it SO EASY to take public trams/buses/metros when traveling now. It’s fantastic not to have to resort to taxis just for lack of easy access to the local transit ticketing system
