However, logistic regression modeling faces challenges such as overfitting, confounding, and multicollinearity when there is a large number of explanatory variables. For example, in the birth defect study presented in this paper, variable selection for building high quality models to identify risk factors from hundreds of pollutant variables is difficult. To address this problem, we propose a novel visual analytics approach to logistic regression modeling for high-dimensional datasets. It leverages the traditional modeling pipeline by providing (1) intuitive visualizations for inspecting statistical indicators and the relationships among the variables and (2) a seamless, effective dimension reduction pipeline for selecting variables for inclusion in high quality logistic regression models. A fully working prototype of this approach has been developed and successfully applied to the birth defect study, which illustrates its effectiveness and efficiency. Spot-Tracking Lens: A Novel Interaction for Animated Bubble Charts Animated bubble charts are fun for visualizing temporal data, but their effectiveness in analysis has been questioned in recent studies. In this paper, we discover the power of animated bubble charts in revealing local, short-lived patterns and maximize this power using a novel spot-tracking lens technique. The basic idea is to design the animated visualization as what can be seen from a zoom camera lens over a focus object. The visualization enlarges local context of the object and automatically tracks its motion with a spotlight during the animation. This spot-tracking scheme utilizes selective visibility with moving focus to allow observers to concentrate on the tracked object and its changing context. The spot-tracking lens can effectively reduce change blindness and enable users to discover volatile local patterns around the tracked object. Those patterns are difficult to capture in static approaches such as small multiples and traces. Our new technique is useful in egocentric visual explorations where users gain insights on unfamiliar objects when observing their relationships with a familiar object. In progressive visual explorations, it can facilitate users in conducting detailed analysis on focal objects and their contexts and thus generate new hypotheses based on the observations. We explore the design space of camera movement, highlighting, labeling, and play control. Several user studies have been conducted to evaluate the effectiveness and efficiency of the new technique. Refreshments will be served.

NCRC Catalysts Annual Symposium Progress in NCRC Date: Location: April 30, 2015 from 11:30 AM to 5:00 PM 150 Research Campus Drive, Kannapolis, NC The NCRC Catalyst Group is comprised of students, fellows, and employees from all of the universities and companies on the North Carolina Research Campus (NCRC) in Kannapolis. This informal group was started in 2010 to allow people from the various schools and businesses on campus to meet each other and foster personal and professional relationships. Since 2011 we have expanded the offerings of the NCRC Catalyst Group to include speaking opportunities for members and host career development events. All activities by the NCRC Catalyst Group are run voluntarily by its members. The Catalyst Group is sponsored by the NC Biotechnology Center, UNC Chapel Hill Nutrition Research Institute and Dole Foods. The Catalyst Group is hosting their fourth annual symposium “Progress in NCRC” on April 30 from 11:30 am to 5 pm in the David H. Murdock Core Laboratory building first floor event room located at 150 Research Campus Drive, Kannapolis, NC. The event includes lunch. The symposium is sponsored by NC Biotech. The UNC Nutrition Research Institute is the sponsor of the poster presentation prizes: an iPad and iPad mini. Postdocs are invited to present a poster and compete for the prizes.

Please plan to join Betty Chafin Rash, Dorothy Counts Scoggins and Friends for a special evening of commemoration and discussion moderated by Steve Crump of WBTV Tuesday, May 5 2015 5:00 – 7:30 p.m. UNC Charlotte Center City Campus Frye Gaillard, author of “The Dream Long Deferred” and Amy Hawn Nelson, co-author of Yesterday, Today and Tomorrow; School Desegregation and Resegregation in Charlotte will share readings and remarks with special guests. A Dream Again Deferred? In 1971, community turmoil and legal wrangling culminated in the fulfillment of a long-deferred dream to pursue equity in education through integrating public schools in Charlotte, NC. In the landmark case of Swann vs. CharlotteMecklenburg, the U.S. Supreme Court ordered that students be bused to achieve racial balance and so began the story of a Southern “city that made desegregation work.” Change was not easy, but a new community spirit emerged from the turmoil of dissent as students, parents, educators, citizens and leaders reached across deep divisions and historic mistrust to choose shared progress over separated futures. School desegregation, once a source of disturbing community strife, became a point of community pride in Charlotte as the Queen City led the U.S. Southeast into a modern, New South era and the nation into a new chapter of American history. A 1999 court decision ended school desegregation in Charlotte-Mecklenburg, leading to increased isolation of public school children by race, ethnicity and socio-economics, and our schools now approach pre-1971 levels of segregation. As our city has grown and changed, so has the complexity of what it means to be desegregated. What does that dream look like in Charlotte in 2015 and beyond? Join us to share our past, understand today and help shape the dream for our future. Event Sponsors: DVA Charlotte Z.
