S registered on the Langley Castle Hotel website to join a team we recorded their 
registration time. The time difference involving when 1 participant registered and when a recruit they recruited registered was the speed of mobilization across that social connection, and is equivalent towards the intersignup time metric utilised in Pickard et al. [2]. The imply mobilization speed was 6.7 and also the distribution was incredibly heavytailed, having a common deviation of 7.2 days (a histogram of mobilization speeds is shown in Fig. S). There was one month amongst registration opening along with the contest end date, and so the mobilization speed distribution was rightcensored; the longest mobilization interval was 26.six days. The essential target of this study was to know the personal traits influencing these mobilization speeds. We collected many pieces of data concerning the participants once they registered on the contest website (see Techniques). We made use of this information to examine the influence of four traits on the speed of mobilization: gender, age, geography as well as the data source from which participants initially heard about the contest (which could be a supply apart from their recruiter). We also controlled for other aspects that could influence the speed of mobilization so as to account for their heterogeneity. We describe these manage variables beneath. We modeled this speed of mobilization using a Cox proportional hazard model (see Approaches), which has been utilized extensively to describe the spreading of epidemics and subsequently adopted to study diffusion processes on social BML-284 web PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24068832 networks, for example product adoption [28]. The Cox proportional hazard model measured the influence of the 4 key traits around the speed of mobilization, controlling for other relevant variables (for goodness of match measures, see Data S).ResultsWe ran a worldwide contest involving timecritical social mobilization, inspired by the Network Challenge contest organized by the Defense Advanced Investigation Projects Agency (DARPA) in the United states of america in 2009, which was won by the Red Balloon Challenge team by utilizing a specific monetary incentive structure [2]. Our contest was for Langley Castle Hotel in Northumberland, Uk. The activity was to seek out 5 knights in parks all through the United kingdom on a specific weekend, each and every with an ID code written on their shield. Contest participants registered around the contest web page, and could recruit other participants onto their team on the internet in numerous strategies (see Solutions). Participants had monetary incentive to kind large teams by recruiting new members, who then recruited other members, and so on (example team structure, Fig. A). The very first registered participant to properly report the position of a knight was awarded ,000. The discoverer’s recruiter also received 00, the recruiter’s recruiter received 50, and so on. This contest incentive structure was previously identified to generate massive social mobilization [2]. Any team that as a entire identified greater than 1 knight would also be awarded a 50 bonus, offered for the group founder to distribute as preferred. Furthermore, the group founders in the first, second, and third largest teams received ,000, 00, and 50 respectively. As opposed to the DARPA contest that was limited to a single nation, two of those knights had been “cyber knights”, present not inside the physical parks themselves but in Google Maps or Google Earth.PLOS One particular plosone.orgHomophily along with the Speed of Social MobilizationFigure .
