Vernetzte Selbsthilfe in Sozialen Medien am Beispiel des Hochwassers 2013 / Linked Self-Help in Social Media using the example of the Floods 2013 in Germany

“…Heger und Reuter (2013) differenzieren zwischen realen "Emergent Groups" (Stallings & Quarantelli, 1985), die meist in Form von Nachbarschaftshilfe auftreten und die Katastrophe vor Ort bekämpfen, und virtuellen "Digital Volunteers" (Starbird & Palen, 2011), die ihren Ursprung im Internet haben und ihre Aktivitäten hauptsächlich online durchführen. "Voluntweeter" werden nach Starbird & Palen (2011) Ein weiterer Forschungsbereich befasst sich mit "Situational Awareness", als das gesamte verfügbare Wissen, das zur Beurteilung und Bewältigung der Situation in ein schlüssiges Bild integriert werden kann (Reilly et al, 2007). Vieweg et al (2010) (Perng et al, 2012).…”

Defined by Sarter and Woods as "all knowledge that is accessible and can be integrated into a coherent picture, when required, to assess and cope with a situation," [28] the SA literature informs our research through the recognition that "reliable information is often an elusive target" [25]. Much of the literature focuses on military and aviation operations [25,27,28], but SA is also studied in domains such as education, weather and emergency response [5,13].…”

“…Even so, activities of structuring and synthesizing become apparent [45]. These studies analyzed how Twitter can contribute to the production of an overall, coherent picture which enables an appropriate response to the developing situation [29], and indicates that tweets including situational updates or geolocations are more likely to be retweeted than others. Volunteer role classifications include "helper", "reporter", "retweeter", "repeater" and "reader" [30] as well as "information broker", gathering and reporting information [46].…”
