Flutracking participation continued to grow, with a total of 33,947 participants in 2017 (a 9.5% increase from 2016). The majority of participants completed their survey within 24 hours of the email being sent (average 72.5% responses received in 24 hours). Overall, the rate of influenza-like illness (ILI) in 2017 was higher and remained elevated for a longer period compared to previous years except for the 2009 pandemic. Flutracking placed the severity and magnitude of the influenza season into historical context. Following the highest number of laboratory-notified influenza cases on record (2.8-fold increase from 2016), Flutracking data demonstrated a large increase in the percent of participants with fever and cough that were tested for influenza (2.9% to 5.0% for 2016 and 2017 respectively) and thus determined it was increased laboratory testing that contributed to the substantial increase in influenza notifications. Flutracking participants with fever and cough that were tested for influenza have increased each year from 2013 to 2017 at the national level, with a large increase from 2016 (2.9%) to 2017 (5.0%). The peak weekly fever and cough attack rate occurred in mid-August, with 4.1% ILI in the unvaccinated, compared to 3.1% in vaccinated Flutrackers. In the peak four weeks of ILI, 12.3% of participants experienced an episode of fever and cough. Divergence between the vaccinated and unvaccinated participants’ ILI percentages was highest during the week ending 6 August 2017 (4.1% in the unvaccinated group and 2.7% in the vaccinated group). The timing of the ILI peak amongst Flutracking participants was consistent with peak notifications of laboratory-confirmed influenza.

In order to study the information communication ability (i.e. information conductivity) of CodePlex C# community, an Open-Source Online Community (OSOC), we first construct the models of weighted communication networks in 11 periods for the community based on large-scale data collections. Then by using two ways of quantum mapping of complex networks, we analyze the localization properties of information on the maximum connected graphs (named as communication networks) of these weighted networks according to the idea of analyzing the localization properties of an electron on a large cluster. We draw the following conclusions. (1) CodePlex C# OSOC usually has information isolativity. (2) The community has some degree of information communication ability and the ability increases as time goes on. (3) The localization of information on the communication networks in any period induced by its structure is weaker than that induced by its structure together with the connection intensities between its nodes. (4) Our idea and methods can be used to analyze the information communication ability of other online communities.

Whether they need Chinese language flash cards, steps and music to a Scottish country dance, physics simulations, or any one of hundreds of other teaching tools, educators and researchers can find them at Apple's Educational Object Economy (EOE) project (http://trp.research.apple.com).The EOE is a complementary online community based around the creation, sharing, and use of teaching resources that incorporate Java applets for web-based learning. Java applets are small, easy-to-use programs written in Sun Microsystem's Java programming language. Using virtually any computer equipped with a standard web browser, educators can access hundreds of teaching and curriculum development tools for use in the classroom, for research, or in other educational endeavors.
