14:26:55 From Martin Andersen : Here is one option: https://www.nytimes.com/interactive/2020/05/06/opinion/coronavirus-us-reopen.html 14:27:03 From Kosali Simon : great 14:29:55 From David Slusky : 49/128 are professors 14:30:14 From David Slusky : 38 are students 14:34:39 From Shooshan Danagoulian to David Slusky(Privately) : You are recording.. I see. 14:35:09 From Shooshan Danagoulian : General information about all the datasets discussed today. https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit#gid=0 14:35:31 From David Slusky to Shooshan Danagoulian(Privately) : yes. I can send you the video 14:35:34 From David Slusky to Shooshan Danagoulian(Privately) : sorry if you wanted to 14:35:40 From Ross Epstein to Shooshan Danagoulian(Privately) : I believe you have to change sharing settings on the doc :) 14:36:04 From Mustafa Hussein : Thanks Shooshan. Access is restricted, though. 14:36:42 From Shooshan Danagoulian : Here is the link again: 14:36:44 From Shooshan Danagoulian : https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 14:37:15 From Shooshan Danagoulian : Is it working now? Please let me know! 14:37:19 From Analisa Packham to Shooshan Danagoulian(Privately) : I also can’t access the google doc (probably since my university doesn’t use Gmail and that’s what I registered with). 14:37:26 From David Slusky to Shooshan Danagoulian(Privately) : not working 14:37:38 From Edward L Kong to Shooshan Danagoulian(Privately) : Doesn't work for me :( 14:37:46 From Yashaswini Singh : Hi Shooshan, access still appears to be restricted. 14:37:57 From Kosali Simon : example news story covering data like this https://www.nytimes.com/interactive/2020/05/06/opinion/coronavirus-us-reopen.html 14:38:04 From Shooshan Danagoulian : How about now? 14:38:05 From Shooshan Danagoulian : https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 14:38:20 From Yashaswini Singh : perfect! works now. thank you. 14:38:21 From Shooshan Danagoulian : Thank you for keeping up with my technology! Hopefully it should work now. Try again. 14:38:21 From David Bradford : That worked! Thanks\ 14:38:26 From Ana Moura : It works for me now, thank you! 14:38:27 From R.G. Childers : worked for me 14:38:38 From Shooshan Danagoulian : Yay!! Here it is again: 14:38:39 From Shooshan Danagoulian : https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 14:43:43 From David Slusky : How does Safegraph know where you are inside? If I'm in a large space with not a lot of windows (e.g., a hotel at a conference) how does it know where I am? 14:43:43 From David Bradford : Question for SafeGraph: I’ve seen the weekly and monthly data, but not the daily (or, heaven forfend) the daily data. Is that more granular time also available? If so, how far back in time does it go? (I know the monthly goes back at least to Jan 2018). 14:45:39 From Shooshan Danagoulian : Responding for SafeGraph: The weekly and monthly data have a JSON field which is a matrix format including daily visitor numbers. So, with both of those datasets you can go back to January 2018 for daily visits to all the POI in the monthly data. 14:46:18 From Kelli Marquardt to Shooshan Danagoulian(Privately) : Hi Shooshan- will you make this group chat/ questions available after the discussion? I don't want to miss out on anything! 14:46:35 From Shooshan Danagoulian : There is also hourly counts available in the weekly data going back to January 2019. Again, as before, the hourly data are included in a matrix format as a variable in the dataset. 14:46:51 From Monica Farid : Related to q above for Safegraph : If a person goes to curbside pick up does it count as having gone to the location? 14:46:59 From Shooshan Danagoulian to Kelli Marquardt(Privately) : Yes, we will save the chat file and the video and post it on ehealthecon.org 14:47:32 From Shooshan Danagoulian : As a reminder, the chat transcript and the video of this session will be available on the ehealthecon.org website in the next few days. 14:47:45 From Kelli Marquardt to Shooshan Danagoulian(Privately) : thank you! 14:47:51 From Shooshan Danagoulian : Here is the google sheet with info again: 14:48:00 From Shooshan Danagoulian : https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 14:48:06 From Ross Epstein : For those who would like a technical deep-dive into SafeGraph’s visit attribution here is a white paper to dive into - https://www.safegraph.com/visit-attribution 14:48:19 From Sara Moran : Nice! Thanks, Ross! 14:50:25 From Shooshan Danagoulian to Ross Epstein(Privately) : Thank you, Ross! Would you like to discuss this a little after the comments are done? Or would you rather I just post it on our website? 14:51:03 From Ross Epstein to Shooshan Danagoulian(Privately) : I think it’s best if I talk through our documentation rather than a specific answer. So everyone can self-serve their own answers, too 14:51:24 From Shooshan Danagoulian to Ross Epstein(Privately) : Great! Then let's get to it after Kate is done with her comments. 14:52:18 From Martin Andersen : In PlaceIQ: how are home locations defined? 14:53:17 From Yashaswini Singh : Question for Ross/Safegraph: what is the best way to adjust the POI visits for longitudinal analysis, given the # of unique devices in the weekly samples are likely decreasing over time (as people shelter in place)? I have seen the various normalization files available for download, curious if there is a recommended approach. 14:54:46 From Shooshan Danagoulian to Kosali Simon(Privately) : Hi Kosali, I am collecting some of the questions that have been asked. So, if you like me to pass them on to you via private chat, let me know. 14:55:04 From Kosali Simon to Shooshan Danagoulian(Privately) : yes please 14:55:38 From Shooshan Danagoulian : Again, the spreadsheet with data information: https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 14:56:29 From Shooshan Danagoulian : The slides will be available on ehealthecon.org in the next few days. 14:58:08 From Shooshan Danagoulian to Kosali Simon(Privately) : Here are some questions: MOnica Farid Related to q above for Safegraph : If a person goes to curbside pick up does it count as having gone to the location? Martin Anderson: In PlaceIQ: how are home locations defined? Yashaswini Singh: Question for Ross/Safegraph: what is the best way to adjust the POI visits for longitudinal analysis, given the # of unique devices in the weekly samples are likely decreasing over time (as people shelter in place)? I have seen the various normalization files available for download, curious if there is a recommended approach. 15:05:08 From Shooshan Danagoulian to Kosali Simon(Privately) : Ross would like to make some comments about the bias in their data. 15:05:46 From Anaka Aiyar : Is ubermedia collecting data at international (non US) sites? Any other datasets from developing countries on mobile use? 15:08:13 From David Bradford : What do you do about POI that are stacked on top of each other, as in multi-story buildings, or packed very tightly, such as medical office buildings where many different provider offices might be. 15:08:36 From Kosali Simon to Shooshan Danagoulian(Privately) : ok, will ask that qn next 15:10:47 From Javaeria A Qureshi : Do you predict the gender or other demographics of the device-holders visiting these locations? 15:11:14 From Shooshan Danagoulian : Question for SafeGraph: Are parking lots included in the polygon? If so, a pick-up in the parking lot counts as visit. 15:12:27 From Shooshan Danagoulian to Kosali Simon(Privately) : More questions: Anaka Aiyar: Is ubermedia collecting data at international (non US) sites? Any other datasets from developing countries on mobile use? David Bradford: What do you do about POI that are stacked on top of each other, as in multi-story buildings, or packed very tightly, such as medical office buildings where many different provider offices might be. Javaeria a Qureshi: Do you predict the gender or other demographics of the device-holders visiting these locations? 15:14:12 From Shooshan Danagoulian : Yes we are glad to have some of that anonymity!! 15:18:51 From Kosali Simon to Shooshan Danagoulian(Privately) : let me know if I have missed any qns 15:19:32 From David Slusky : and did they correlate? 15:19:34 From Shooshan Danagoulian to Kosali Simon(Privately) : I think this is all. I had asked questions about parking lots in location. 15:20:13 From Shooshan Danagoulian to Kosali Simon(Privately) : Are parking lots included in the polygon? If so, a pick-up in the parking lot counts as visit. 15:21:01 From Shooshan Danagoulian : Spreadsheet on the datasets: https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 15:21:51 From Kosali Simon to Shooshan Danagoulian(Privately) : will end fairly soon after asking any last words from panelists? 15:22:01 From Kosali Simon to Shooshan Danagoulian(Privately) : will remind on google sheet 15:22:08 From Shooshan Danagoulian to Kosali Simon(Privately) : Yes, we should keep it to about an hour. 15:22:10 From Kosali Simon to Shooshan Danagoulian(Privately) : anything on next week's seminar? 15:22:34 From Shooshan Danagoulian to Kosali Simon(Privately) : Next week we have Osea Giuntella. The website has the seminar details. 15:24:06 From David Bradford : I realize this isn’t possible with the data that is being provided to the community now, but I wonder if the companies have the capability of tracking cluster of travel. For example, would it be possible in principle to see flows of traffic that visit a physician office and then see which pharmacies they then go to? 15:25:40 From David Slusky : Do you release a version of this data for calculating traffic rates? 15:25:51 From Shooshan Danagoulian : It's not possible to track individual devices across time with the datasets that are available. However, the datasets provide information about Census Block Groups of visitors to a POI, which allows you to see upticks in pharmacy visits after an uptick in physician visits. 15:28:53 From Shooshan Danagoulian : Here is the link again: https://docs.google.com/spreadsheets/d/1U8ovq22ob-5BykDbCMUAXDRQuTVGYdozlUuLunyMRBo/edit?usp=sharing 15:29:50 From David Slusky : https://umn.zoom.us/webinar/register/WN__8ifIKPiQiyIKQyX5ifgIg 15:29:54 From Lucy Xiaolu Wang to Shooshan Danagoulian(Privately) : Thank you! Glad to “see” you here! 15:30:02 From Shooshan Danagoulian to Lucy Xiaolu Wang(Privately) : Glad to see you! 15:30:02 From David Slusky : "Why Don’t We Sleep Enough?
