“…This event connects to the broad empirical generalization of immediacy, reach, distribution, access, temporal flexibility, and interactivity as affordances of social media as well as digital and mobile technologies (cf. Brabham, 2013).…”

“…Brubaker, Hayes, & Dourish, 2013;Christensen & Sandvik, 2014;Gustavsson, 2011;Lingel, 2013;Mitchell, Stephenson, Cadell, & Macdonald, 2012;Prigerson & Maciejewski, 2005). The immediacy, reach, distribution, access, temporal flexibility, interactivity, and a rapidly developed informal mentorship and sharing of experiences among members in the online communities have been identified as general important features of social media (Brabham, 2013). However, how this is configured in coping with the loss of a child is still an under-researched subject, with some exceptions (e.g.…”

The purpose of this paper was to study bereaved parents' use of a closed peer grief support community on Facebook and the features of the community that are important to them. The death of a child is an uncomfortable subject in most contemporary societies. This limits the exploration of experiences and possibilities for coping with grief. However, with the introduction of social media, this has changed. Theoretical perspectives on parental grief recognizing the importance of continued relational bonds with the lost child are used, together with the ontological assumption that social media enhance the dissolving of private/public and time/space. This study is based on questionnaire, interviews, and content from the closed peer grief support community, to which the research team has insider access. The community encompasses a diverse range of experiences and stages of grief, independent of the time elapsed since the loss of a child. Bereavement of children of all ages and from all conceivable causes of death is distributed among the members. The results show how the affordances of social media become vital resources for coping with grief in ways not available previously, comprising aspects of the closed nature of the group, shared experiences, time, and accessibility.

“…Developing and deploying crowdsourced annotation tools for law enforcement involve many issues. For example, as described in [32], protecting the video contents and allowing freedom of speech to the annotators while avoiding chaos and protests are some potential issues. Therefore, there are issues when using commercial crowdsourcing tools such as MTurk for this purpose.…”

A web-based video annotation system for crowdsourcing surveillance videos

et al. 2014

Video surveillance systems are of a great value to prevent threats and identify/investigate criminal activities. Manual analysis of a huge amount of video data from several cameras over a long period of time often becomes impracticable. The use of automatic detection methods can be challenging when the video contains many objects with complex motion and occlusions. Crowdsourcing has been proposed as an effective method for utilizing human intelligence to perform several tasks. Our system provides a platform for the annotation of surveillance video in an organized and controlled way. One can monitor a surveillance system using a set of tools such as training modules, roles and labels, task management. This system can be used in a real-time streaming mode to detect any potential threats or as an investigative tool to analyze past events. Annotators can annotate video contents assigned to them for suspicious activity or criminal acts. First responders are then able to view the collective annotations and receive email alerts about a newly reported incident. They can also keep track of the annotators' training performance, manage their activities and reward their success. By providing this system, the process of video analysis is made more efficient.

“…Those concepts mainly comprise support for a greater participation and integration of citizens into the tasks and activities of professional organizations [3]. Crowdsourcing is a "type of participative online activity in which an individual, an institution, a nonprofit organization, or company proposes to a group of individuals via a flexible open call, the voluntary undertaking of a task" [9].…”

Emergencies such as the 2013 Central European flood or the 2013 typhoon Haiyan in Philippines have shown how citizens can organize themselves and coordinate private relief activities. These activities can be found in (physical) groups of affected people, but also within (digital) social media communities. There is an evident need, however, for a clearer picture of what exactly is going on to be available for use by the official emergency services: to enlist them, to keep them safe, to support their efforts and to avoid needless duplications or conflicts. Aligning emergency services and volunteer activities is, then, crucial. In this paper we present a mobile crowd sensing based concept, which was designed as well as implemented as the application CrowdMonitor and facilitates the detection of physical and digital activities and the assignment of specific tasks to citizens. Finally we outline the findings of its evaluation.
