e humanitarian sector is entering in the network age. e explosion in access to new information and communication technology (ICT) like mobile phones, the internet, and social media, is changing the way people communicate in emergency situations. However, the use of new ICT has not yet been adequately accompanied by an analysis of the challenges it represents for the application of the four humanitarian principles, namely humanity, neutrality, impartiality and independence. ese principles provide the foundations for humanitarian action and are central to establishing and maintaining access to a ected people. is article addresses that issue and provides a design framework to guide humanitarian agencies towards a principled approach to ICT.

“…In this paper, we study gossip in smartphone peer-to-peer networks, an interesting emerging networking platform that makes use of the peer-to-peer libraries included in standard smartphone operating systems (for examples of these networks in practice, see: [23], [1], [22], [18], [17], [11], [12]). We begin by improving the best-known synchronous gossip algorithms in this setting, and then build on these results to describe and analyze the first efficient asynchronous solution.…”

In this paper, we study random gossip processes in communication models that describe the peer-to-peer networking functionality included in standard smartphone operating systems. Random gossip processes spread information through the basic mechanism of randomly selecting neighbors for connections. These processes are well-understood in standard peer-to-peer network models, but little is known about their behavior in models that abstract the smartphone peer-to-peer setting. With this in mind, we begin by studying a simple random gossip process in the synchronous mobile telephone model (the most common abstraction used to study smartphone peer-to-peer systems). By introducing a new analysis technique, we prove that this simple process is actually more efficient than the best-known gossip algorithm in the mobile telephone model, which required complicated coordination among the nodes in the network. We then introduce a novel variation of the mobile telephone model that removes the synchronized round assumption, shrinking the gap between theory and practice. We prove that simple random gossip processes still converge in this setting and that information spreading still improves along with graph connectivity. This new model and the tools we introduce provide a solid foundation for the further theoretical analysis of algorithms meant to be deployed on real smartphone peer-to-peer networks. More generally, our results in this paper imply that simple random information spreading processes should be expected to perform well in this emerging new peer-to-peer setting.

“…While traditional social media such as Facebook require an Internet connection, co-located social media can overcome the connectivity challenge by running on a local server or an ad hoc network [28]. For refugee communities, this is important: a stable Internet connection is not always guaranteed due to lack of infrastructure, excessive cost, and policy disputes [53,54].…”

While co-located social media previously has been employed to enhance interaction in community building activities in previous work, its range of e ects have not been quantitatively described. In this study, we introduce a co-located social media app called SpeakUp to a community building project in the Za'atari Syrian refugee camp in Jordan. To overcome issues such as the lack of Internet access, we purposefully adapted the design of the application and ported its server to a low cost single board computer on a Raspberry Pi. We explore the e ects of SpeakUp through eld experiments with one control and two treatment groups, as well as with interviews and observations. Our results show that SpeakUp signi cantly increases refugees' level of participation and sense of community. Importantly, with the use of the application, female and male participants demonstrate no signi cant di erences in participation, showing that the use of such applications can be equalizing. We also found that co-located social media supports asynchronous interaction when outside-the-classroom activities are involved.
