<p>Description:</p>
<p>This is map of the conference attendance by organization depicting the zip code that the organization is located in. The symbol scale is a single color value from lightest (meaning smaller number of participants) to a darker value (meaning a larger number of attendees).</p>
<p>The time scale is inclusive of all data from 1994 - 2014. The map was produced using Version 7 of the data that was processed to remove records lacking location information (mostly in the year 1994).</p>
<p>From this interactive map we can discern that the number of attendees summarized by Zip Code for the years 1994 - 2014. The trend is readily visible; clearly showing the center of gravity for participation in the Tutor/Mentor network has been in the zip codes in the immediate vicinity of the City of Chicago; with varying degrees of participation from outlying zip codes over the 20 years analyzed.</p>
<p><strong>Processing Notes:</strong></p>
<p>Software utilized --</p>
<p>The Zip code boundary files were downloaded from the US Census Bureau Tiger Line website.</p>
<p>Using QGIS (Open Source Desktop Software -- <a target="_blank" class="external" href="https://www.qgis.org/en/site/forusers/download.html%29"><span><span>https://www.qgis.org/en/site/forusers/download.html)</span><span class="screenreader-only"> (Links to an external site.)</span></span></a>; the Zip Code layer was intersected with the final version of data as described above. The point file of the attendees was processed using the tool: Points in Polygons (Vector > Analysis Tools > Points in Polygon). This resulted in a polygon layer which counted the number of points per polygon.</p>
<p>The dataset was then saved to GeoJSON file format and uploaded to the online mapping system CartoDB (<a target="_blank" class="external" href="http://cartodb.com/%29."><span><span>http://cartodb.com/).</span> <span class="screenreader-only"> (Links to an external site.)</span></span></a></p>
<p>This tool was chosen to display the geographic information as it provides a platform for sharing the information. The low-cost (free) account can easily be used to display and share gathered geographic information.</p> Since January 2015 I've been…tag:tutormentorconnection.ning.com,2015-04-26:783429:Comment:581702015-04-26T20:22:29.601ZDaniel Bassillhttps://tutormentorconnection.ning.com/profile/tutormentor
<p>Since January 2015 I've been serving as a client for an Information Visualization MOOC hosted by Indiana University. Four students have been looking at attendance data for Tutor/Mentor Leadership and Networking Conferences held in Chicago since May 1994. Their final projects are now available.</p>

<p>The story that this is trying to tell is about history and trends in participation. The map depicts organizations as nodes, and each is related only to the Tutor Mentor Connection (the conference organizer). The size of the node is showing how many times an organization has attended: the larger the node the more times they have attended, the smaller the node the less frequent. The color of the node is showing how recently an organization has attended: the lighter in color (in the yellow spectrum) the less recent, and the darker the color (in the darker blue) the more recent. The organization affiliation is distinguished by the color of the node label: program in green, non-program in pink.</p>
<p>What I'm hoping this map helps show is: who is attending, how often are they attending, and how recently have they attended. Ideally answers to questions like: what organizations have come in search of help? are they still attending? what organizations have come offering help? are they still attending? These questions and answers might lead to follow-up contact to find out how things are going. Are effective and valuable relationships being built? Or, if an organization has stopped attending the follow-up might inquire into the reasons why. Perhaps additional help is needed, or perhaps different categories of help are needed. Answers to these might drive the campaigning of organizations to attend.</p>
<p><strong>Notes about the analysis and visualization:</strong></p>
<p>- the analysis was performed on the V6 data set</p>
<p>- the visualization was done using Gephi, and Inkscape</p>
<p>- the grouping of attendance by organization yielded 1776 nodes; this made the map virtually unreadable</p>
<p>- the collection was filtered to those who attended 4 or more times; this resulted in the 167 nodes presented in the visualization</p>
<p>Some changes I would make, given the time, which I think would improve the visualization:</p>
<p>- node placement: given the length of many labels, there is a lot of overlap which makes some unreadable</p>
<p>- implement filtering in the analysis so that we can add smarter heuristics: the range filter in Gephi is eliminating nodes based on count (attendance) regardless of the recency (year); we should prefer to keep the attendees from the 2 most recent years in the visualization</p>
<p>- add an indicator of sparseness and/or continuity of attendance</p>
<p>- add an indicator of the number of attendees (avg, min, max) from each organization</p> I have been cleaning up the a…tag:tutormentorconnection.ning.com,2015-02-06:783429:Comment:571322015-02-06T22:50:12.166ZDaniel Bassillhttps://tutormentorconnection.ning.com/profile/tutormentor

<p>When researchers look at the conference lists they can pull out information like this. One group I'd like them to look at is participation from other cities and states. People who came to the conferences in the late 1990s have gone on to lead, or help create, mentoring partnerships in Kansas City, Michigan, Minneapolis and Long Beach, California. These were just a few of the cities/states beyond Chicago who participated and, hopefully, took ideas from Chicago to use in their own efforts. A map showing such people would be interesting and perhaps helpful in building new connections.</p>
