PeriodO Advisory Committee Meeting Update (2017-09-25)
http://perio.do meeting notes: Lex Berman
The PeriodO project has developed methods for organizing, comparing, searching and – most importantly – referencing named historical periods as linked data.
Now in a second round of funding, the project is working on improving its search, reconciliation, and visualization services, and is reaching out to other projects and organizations in the spheres of digital humanities, libraries and spatio-temporal information retrieval to create a common framework for using the historical period definitions in all manner of queries and analytical processes.
Content Update
1. adding as a batch ingest, the Library Of Congress subject headings for named period to PeriodO, to achieve a Lowest Common Denominator approach, rather than a fine-grained integration of many specialized time periods from various sources. See progress: https://test.perio.do/#/p/Canonical/periodCollections/p06c6g3/
2. adding 18th and 19th Century entries to reveal how the concept of the periodization changed historically. Examples of these collections: http://n2t.net/ark:/99152/p05hrsf ; http://n2t.net/ark:/99152/p0jf288
3. adding periods from graphical sources, such as those found in Cartographies of Time, by Daniel Rosenberg. https://www.papress.com/html/product.details.dna?isbn=9781568987637
4. examine the way in which historical periods are represented in EpiDoc with the objective of being able to integrate period definitions to and from PeriodO. https://sourceforge.net/p/epidoc/wiki/Home/
5. reaching out to new potential collaborators, such as
Digitizing Early Farming Cultures (Austrian Centre for DH) https://defc.acdh.oeaw.ac.at/
Inscriptions of Israel & Palestine (Brown Univ) http://cds.library.brown.edu/projects/Inscriptions/
Technical Update
1. adding “derivedFrom” relations to the data model, using the Provenance Ontology https://www.w3.org/TR/prov-o/
2. adding Broader and Narrower terms from the SKOS vocabulary https://www.w3.org/2009/08/skos-reference/skos.html
3. adding “conflationOf” relations, which will enable users to pick their own subset of named periods and group them into a single entity, as in their own preferred representation of a period (by leaving out those they specifically do not want to include). No existing vocabulary was identified yet.
4. language tags are being switched from 3 character codes (including script definitions) back to 2 character codes. See: http://perio.do/technical-overview/#labels-and-documentation
5. discussed the use of Language references as URIs, such as http://www.lexvo.org/linkeddata/faq.html
6. refered to methods for the annotation of items with specific assertions and source citations. Recommended to investigate the use of http://nanopub.org/wordpress/?page_id=65 (possibly for other projects, rather than PeriodO).
7. the timeline (time range) histogram is being redesigned as a stand-alone D3 block with more functionality.
8. discussed the general methods for spatio-temporal concepts in the case of data reconciliation. Since OpenRefine lacks specific methods for spatio-temporal filtering, PeriodO has it’s own method: https://github.com/periodo/periodo-reconciler

Speaker: Tina Cormier, Remote Sensing Scientist, Tellus Labs
Location: CGIS South S354 12pm to 1:30pm
Watch the presentation on Youtube
In this presentation, Tina Cormier, will explore vector GIS, raster processing, lidar data, and cartography with R, an open source software environment and programming language that is well-positioned to have an impact in the rapidly emerging field of geospatial data science.
Widely used among academics, scientists, and data science practitioners, R is a flexible platform for both statistical computing and beautiful, fully customizable graphics. A recent surge in the development of geospatial packages has enabled R to become a fully functional command line GIS as well.
Taking a case study on forest biomass mapping, Cormier will demonstrate the utility of R methods across the full range of the research process.

Presented at the North American Cartographic Information Society annual meeting.
October 21, 2017, Colorado Springs.
Cartograms that show a statistic in the form of equal sized blocks allow the map reader to quickly compare quantities across an area. However, at the time of this project, there existed no tool or algorithm that automatically converts a GIS shapefile into a block cartogram. This talk will detail an approach that produced a block cartogram for a Texas County shapefile using data manipulation in Excel and the Cartography Toolbox in ArcMap.

Presentation at the 38th Annual Meeting & Scientific Sessions of the Society of Behavioral Medicine
San Diego, CA
March 30, 2017
Introduction: Societal appearance ideals drive consumer demand for UV indoor tanning, which now generates approximately $3 billion in revenue annually in the US. The rapid growth and infiltration of UV tanning into other industries (e.g., gyms) has been followed by a corresponding rise in melanoma. While proximity to businesses offering UV tanning is likely an important predictor of use by consumers, little is known about their geographic distribution. Methods: In fall 2014 and 2015, we gathered phone survey data on whether businesses offered UV tanning from 21,387 businesses in 7 major U.S. metro areas (Boston, NYC, Chicago, Seattle, LA, Dallas, Miami). We then linked business survey data to block group characteristics (sociodemographics, land use, presence of businesses of all categories) to build multivariable logistic regression models to predict probability of businesses offering UV tanning. We generated predictive maps of the spatial distribution of these businesses. Results: UV indoor tanning services were reported in the highest prevalence by tanning salons (90.2%), health clubs (17.3%), gyms (10.8%), and laser-treatment and tattoo-removal businesses (both 8.0%). The probability of UV tanning services in a block group was positively associated with percent of population of white race/ethnicity (p<0.01) and higher density of businesses (p<0.05) and negatively associated with percent of population with college degree (p<0.05). Sunbelt metro areas (Miami, Dallas, LA) had lower prevalence of businesses offering UV tanning compared to northern areas (p<0.01 for all 3 metros). Discussion: We observed important variability in spatial distribution of UV tanning. Presence of these noxious services may both normalize UV tanning as a societally valued behavior and increase use by nearby residents. Societal idealization of tanned skin, particularly in populations of white race/ethnicity with lower education in northern cities, fuels demand for UV indoor tanning, putting consumers at elevated risk for melanoma.
