Sentiment score of relevant posts identified from social media by date.
<p>Relevant posts mentioned impact of unplanned school closure due to Chicago teachers’ strike from September 8–21 (two days before to three days after strike) on students and their families (N = 930). Sentiment score was calculated as: (positive posts—negative posts)/(positive posts + negative posts + neutral posts)<sup>a-b</sup>. <sup>a</sup>Sentiment score < 0 suggests negative sentiment; score > 0 suggests positive sentiment. <sup>b</sup>Score on September 21 reflects only four relevant posts, all expressing negative sentiment.</p

Online work force analyzes social media to identify consequences of an unplanned school closure – using technology to prepare for the next pandemic
We used the social media-monitoring platform Radian6
(San Francisco, CA) to retrospectively capture social media posts related to
the Chicago City School District closure in September 2012. Social media in dataset include posts from Twitter, Facebook, blogs, forums, and comments
between September 8 and September 12, (two days before the strike started to
two days after the strike ended). We used the following combination of search
terms: “strike Chicago” AND “breakfast” OR “childcare” OR “daycare” OR “lunch”
OR “parent”.  A proximity score of “5” was
applied to the terms “strike” and “Chicago” (on a scale of 1–20, with 1 being
exact [i.e., strike and Chicago together]).<div><br></div><div>Column headings include: Â Unique post identifying number (NUMBER), post content (CONTENT), social media provider (MEDIA_PROVIDER), and publishing date/time (PUBLISH_DATE). Â </div><div><br></div><div>These posts were reviewed and categorized as relevant (related to impact of closure on students and their families) or irrelevant (describing political aspects of strike, welfare system, or other unrelated topics). Â Relevant posts were further analyzed for underlying sentiment (positive, neutral, or negative).</div

Week 1 ILI rate prediction for HHS regions 6–10 from influenza seasons 2004–2005 to 2012–2013.
<p>Note: 1) Auto-regressive integrated moving average (ARIMA [<i>p</i>, <i>d</i>, <i>q</i>]) method, in which <i>p</i> represents the number of auto-regressive terms, <i>d</i> is the number of non-seasonal differences and <i>q</i> is the number of lagged forecast errors in the prediction equation; 2) 95% prediction intervals were calculated by bootstrapping the model error 5,000 times; and 3) the point estimate and prediction interval were bolded if the observed ILIs rate were not covered by the 95% prediction interval.</p><p>Week 1 ILI rate prediction for HHS regions 6–10 from influenza seasons 2004–2005 to 2012–2013.</p
