15:15-15:45 Co ee Break (West Foyer) Closing Plenary & Keynote: Patrick Meier 15:45-17:15 (Grand Ballroom 5 & 6) 1 About the Technical Program

The CSCW research community is expanding at a tremendous pace. This year, we received a record 497 sub- missions – an increase of 27% from last year. Authors from 38 countries on 6 continents submitted papers. We accepted 134 papers for an acceptance rate of 27%. The growth in the number of submissions speaks to the increasing interest in CSCW. The papers range from traditional topics of interest to the CSCW community such as collaboration in work settings to newer topics such as crowdsourcing and social computing. The papers presented in this year’s conference highlight the intellectual diversity of research in CSCW.

This was also the third year for the revise and resubmit (R&R) process for the conference. Similar to the process last year, we did not have page limits for the submissions, nor did we have a separate submission category for “notes” (short papers); rather, research contributions of any length were considered for the papers category. Out of the 497 papers submitted to the conference, 43% were invited to be revised and resubmitted. The over- all response to the R&R process has been very positive. Many of the accepted papers were greatly improved through the revision process.

We would especially like to thank the external reviewers and Program Committee (PC) members. The revise and resubmit process would not be possible without the dedicated work of the reviewers and PC members. We had one of the largest PCs for CSCW with 64 members representing both the intellectual and geograph- ical diversity of our community. This was a particularly challenging year for reviewing because of the record number of submissions and the reduced time frame for the review process. Without the amazing efforts of the PC members and external reviewers, we would not have been able to present the outstanding set of papers in the conference. Enjoy!

An evening of dinner, drinks, and high-energy networking in the heart of the Aquarium’s Pier 4 Pavilion. The Atrium provides two stories of social space with plenty of conversation nooks. Two adjoining exhibits will remain open during the reception: “Dolphin Discovery,” the residential complex for the Aquarium’s dolphin community, and “Jellies Invasion: Oceans Out of Balance,” a mesmerizing exhibit showcasing different species of jellyfish.

11 Saturday, 9:00 – 17:00 Saturday/Sunday Workshops

Workshops provide a valuable opportunity for small communities of people with diverse perspectives to engage in rich day-long discussions about a topic of common interest. Workshop participants are pre-se- lected based on submitted position papers. Look for the results of workshop activities to be on display at the Interaction Reception on Monday evening.

Workshops start at 9:00 with coffee breaks at 10:15 and 15:15. Lunch is included.

59 Welcome to Baltimore!

The city of Baltimore has a rich history spanning nearly 300 years. The second largest seaport in the Mid-Atlantic, Baltimore was once second only to New York as an immigration entry point, fueling diversity and population growth. The city also played a major role in the War of 1812, with Francis Scott Key famously penning the Star Spangled Banner during the Battle of Baltimore. Today, the city contains a thriving metropolitan region of nearly three million people and sits 45 minutes north of Washington, DC. The Marriott Waterfront’s location at the eastern end of the Inner Harbor places CSCW attendees near several popular neighborhoods, including Little Italy and Fells Point, as well as the harbor itself, which isWelcome a popular tourist location that boasts the National to Aquarium, Science Center, Port Discovery, and a wide range of food and entertainment options. Baltimore is also a hotspot for arts, history, and culture, ranging from the Baltimore Symphony Orchestra and Peabody to the Mu- seum of Industry and Fort McHenry. Finally, sports fans will note the much-vaunted stadiums for the Orioles and Ravens on their drive into the city. All in all, there is never a shortage of things to do in this vibrant city on the ChesapeakeBaltimore Bay!
