“Twitter can predict hurricane damage as well as emergency agencies”

twitter fileJohn Bohannon of Science News reports on a recent study by Yury Kryvasheyeun, a research at Australia’s National Information and Communications Technology Research Centre of Excellence in Melbourne.Kryvasheyeun’s team demonstrated that twitter data collected during Hurricane Sandy in 2012 can be a better predictor of damage that FEMA’s models for a fraction of the cost. Their predictions were robust even accounting for confounding factors the millennial bias of twitter users and the existence of twitter bots. This approach to data analytics could be a major step in the modernization of fast and effective disaster relief efforts. Kryvasheyeun hopes to scale up the potential of social media in this realm by incorporating a richer Facebook data set.

“Super Bowl Weaving Twitter”

Screen Shot 2016-03-11 at 10.18.16 AMCheck out this Superbowl 50 Twitter data interactive created by Luis Natera of cuidadpixel. Interestingly, Lady Gaga trends higher than either team that participated in the game. Natera highlights the differences between the people who tweet about artists vs about athletes as well as the powerful reach of advertisements for companies like Doritos and Esurance.

You can play around with the interactive HERE.

“There’s hidden code inside Facebook that can let you stalk your friends’ sleep patterns”

cb04noeweaem7d_Rafi Letzter of Tech Insider reports that Facebook Messenger has a feature capable of sending information about when other users are online to your computer in plain text. Soren Louv-Jansen used this to write a program that checked Facebook every ten minutes and recorded these timestamps. With that data, he could tell when his friends put turned on their phones in the morning and logged off at night, resulting in a database of his friend’s sleeping schedules. This news is particularly interesting in the wake of Lab Director, Noshir Contractor‘s recent article in PLOS One “Circadian Rhythms in Socializing Propensity.” His team found that the time-of-day that people use social media has a significant effect on the connections the forge. Though most people socialize online in the evenings, the most meaningful communications and friendships occur late at night, when not many people are awake. The research suggest that the presence of oxytocin at that point in the human circadian cycle encourages this deep bonding.

On February 23r, 2016, Charles “Chick” Macal visited SONIC Lab to present “Simulating Chicago (and Everyone in It)” as part of the SONIC Speaker Series. Dr. Macal’s full abstract and presentation can be viewed below.

Abstract:

chiSIM, the Chicago Social Interaction Model, is an agent-based model of people and places in Chicago along with the daily activities in which residents engage. To support planning and policy making, chiSIM models the behaviors and social interactions of all Chicago residents, represented in the model at the individual level. Places consist of geo-located parcels in the city, such as households, schools, workplaces, hospitals, and general quarters, such as nursing homes, dormitories, jails, etc. During the course of a simulated day, agents move from place to place, hour by hour, engaging in social activities and interactions with co-located agents. Examples of applications for this model include forecasting socially mediated processes, such as the spread of infectious diseases and the adoption of new technologies; measuring the potential effectiveness of public health and social programs and interventions; and assessing population-wide energy usage.

“Scientists are using sound to track how sharks migrate and the animals they encounter”

Image credit: Danielle Haulsee

Emily DeMarco of Inside Science reports that researchers from the the University of Delaware are fitting Delaware Bay tiger sharks with devices to track them during their southward migration. These researchers are interested in, not just where they go, but how the sharks interact with each other and other animals during their long swim.

The team implanted acoustics transceivers into 350 adult tiger sharks staring in 2012. They found that when the sharks migrate south, they become extremely dispersed into small male-dominated groups. However, when the sharks migrate back north to the Bay of Delaware, the network of sharks “fuses” back together with both male and female sharks mixing together again.

This data illustrates the social networks of sharks. The dispersion-fusion behavior they display is typically associated with higher-order mammalian species like dolphins and elephants. Evidence of this pattern in the Delaware population suggests that sharks could have more complex social networks than perviously conceived.
