      1. Another predictor of illiteracy is the number of incoming texts and how they differ from the number of outgoing texts. That could be because people do not send texts to others who they know are illiterate, points out Sundsøy.
      2. If it does, the potential to improve lives is huge. Low levels of literacy lead to a vicious cycle of poverty. People who are functionally illiterate are unable to fill in job applications, read medicine labels, write checks, or balance their accounts. This makes them more likely to be unemployed, to have poor health and to be dependent on social welfare or charity. Neither are they able to help their children learn to read and write. Ending this cycle is an important goal.

      "We evaluate the automatically assessed vowel space in experiments with a sample of 253 individuals and show that the novel measure reveals a significantly reduced vowel space in subjects that reported symptoms of depression and PTSD," the USC team concludes. "We show that the measure is robust when analyzing only parts of the full interactions or limited amounts of speech data, which has implications on the approach's practicality. Lastly, we successfully show the measure's statistical robustness against varying demographics of individuals and articulation rate."

      Android applications don’t do much without external input, they need to talk to things. With more and more devices becoming internet connected, the apps you write will communicate with them. You might think you get away with this because the devices talk to the server and you just obey the server. However, security and performance being high value requirements for mobile, potentially having your Android apps talk to IoT devices on local networks or pairing with them one on one are highly crucial features.
