Social media: an emerging data source for human mobility studies
While most previous studies relied heavily on the expensive travel-diary type data, social media now emerges as a new data source to describe human daily activity patterns and population dynamics. Despite the various appealing aspects of social media data, including a much larger numbers of “subjects,” low acquisition cost and relatively wide geographical and international coverage, these data also have many limitations, including sparseness and irregularity of sampling points over space and time, and the lack of background information of users, such as home locations and socioeconomic status (SES).

Mining social media can help improve disaster response efforts
Leveraging publicly available social media posts could help disaster response agencies quickly identify impacted areas in need of assistance, according to a Penn State-led team of researchers. By analyzing the September 2013 Colorado floods, researchers showed that a combination of remote sensing, Twitter and Flickr data could be used to identify flooded areas.

Hope we did not catch you catnapping. “Dog” may be our catchword, but this week’s animal companion is no canine. Will this catalyze you to send in a photo of your animal companion? Who is this feline? Who are her humans?
