	abstract = {Uneven access to Information and Communication Technologies (ICTs) in parts of the African continent make it challenging for some Africans who migrate to the U.S. to communicate with family members in their countries of origin. However, Internet access is becoming more widespread throughout the continent and this development presents an opportunity to explore how future interactive systems can support exchanges between families with members living in developed and less developed countries. To investigate these design possibilities we interviewed 27 African-born students, currently living in Virginia, U.S., and asked them how they used ICTs to connect with family members in their home countries. Our findings informed the development of a low-fidelity prototype that eight students lived with for four to five months. Findings from this deployment study motivate a discussion regarding features to include in interfaces designed to support transnational family communication. Features include personally meaningful imagery, country specific content, and the ability to monitor the weather and changing currency rates in migrants{\textquoteright} countries of origin.},

	abstract = {When analyzing thousands of event histories, analysts often want to see the events as an aggregate to detect insights and generate new hypotheses about the data. An analysis tool must emphasize both the prevalence and the temporal ordering of these events. Additionally, the analysis tool must also support flexible comparisons to allow analysts to gather visual evidence. In a previous work, we introduced align, rank, and filter (ARF) to accentuate temporal ordering. In this paper, we present temporal summaries, an interactive visualization technique that highlights the prevalence of event occurrences. Temporal summaries dynamically aggregate events in multiple granularities (year, month, week, day, hour, etc.) for the purpose of spotting trends over time and comparing several groups of records. They provide affordances for analysts to perform temporal range filters. We demonstrate the applicability of this approach in two extensive case studies with analysts who applied temporal summaries to search, filter, and look for patterns in electronic health records and academic records.},
