We've moved!
Our office has recently moved to a new location. Please see our Contact Us page for updated contact information. To make the transition as smooth as possible for our clients, our toll-free number remains the same and our previous phone and fax numbers have been redirected to our new numbers.

We would like to encourage you to start using our new phone number as soon as possible because our voicemail service can be unreliable when calls are forwarded from the old number, which may result in unanswered calls.

We're celebrating our fifteenth anniversary!
We would like to thank all of our clients, business partners and friends for their continued support and invaluable feedback.

Electronic Diary project celebrates first year of use
Discerning Systems is pleased to announce a successful first year of service for its Electronic Diary application as part of the study "Social-Emotional Contexts of Adolescent Smoking Patterns" led by Dr. Robin Mermelstein (University of Illinois at Chicago).

The Palm Pilot application helps researchers gain insight into teen behavior by taking complete control of the device to query participants randomly throughout the day for a week. The password-protected diary also allows students to record feelings and suspend alarms or delay responses to random prompts for 'quiet times' as well as recording its own operation and user actions.

At the end of the week all responses and usage logs are uploaded to a laptop where our conduit program converts the information from the Palm data file to a PC database to create in-field reports and files for later submission to a central server. To date the Electronic Diary has been used by over 450  students in the Chicago area. For more information see http://www.healthconnectionsstudy.org

06.30.04 Automated Windows Updates may cause DUMPStat and CARStat analyses to fail
DUMPStat and CARStat analyses may stop functioning for no apparent reason. We have determined that Automated Windows Updates are the cause. Correct  operation may be restored by updating to DUMPStat or CARStat 2.1.8 which addressed this problem when they were updated for Windows XP. Download the programs from DSI Software Updates and install them on top of your current versions.  Do not uninstall your existing versions prior to updating them.

03.24.04 Website and e-mail problems
On Thursday, March 18, 2004 our website and e-mail services experienced intermittent outages. We were told by our hosting company (Symplexity.net) that the problems would be corrected. Friday conditions worsened but service was partially restored for brief intervals during the weekend.

Early Monday morning everything went down again and this time for good. The datacenter (ThePlanet.com) told us that the problems originated with our host while our host continued to blame the datacenter. Late Monday we received word that ThePlanet would no longer host any of Symplexity's servers. We engaged a new web hosting company and set up our website and e-mail on Tuesday.

The website and e-mail should be completely operational now but some e-mail may have been lost during the transition. If you sent us e-mail and did not receive a reply, please resend it. We apologize for any inconvenience that you may have experienced during this period.
