Th e past two decades have seen a proliferation of largeand small-scale experiments in participatory governance. Th is article takes stock of claims about the potential of citizen participation to advance three values of democratic governance: eff ectiveness, legitimacy, and social justice. Increasing constraints on the public sector in many societies, combined with increasing demand for indivi...

The reconstruction of an unknown temporal-spatial profile from participatory sensing data poses a number of challenges due to uncoordinated user movement and possibly low user involvement. This paper considers the problem of reconstructing such a profile from participatory sensing data by exploiting the theory of compressive sensing. In particular we study the impact of the number of users and ...

Mobile phones have evolved from devices that are just used for voice and text communication to platforms that are able to capture and transmit a range of data types (image, audio, and location). The adoption of these increasingly capable devices by society has enabled a potentially pervasive sensing paradigm participatory sensing. A coordinated participatory sensing system engages individuals c...

Collaborative peer production systems like Wikipedia and Flickr succeed (and fail) based upon the voluntary participation of the users of those systems. Individual user participation varies and is influenced by any number of different variables. Research in peer production systems has thus far analyzed them in a non-experimental fashion and has been unable to address why certain behaviors occur...

Basierend auf der prekären Pflegesituation für Menschen mit Demenz (MmD) ist es notwendig neuartige Lösungskonzepte zu entwickeln. MmD zeigen im Krankheitsverlauf Verwirrung, Orientierungslosigkeit, Fehleinschätzung von Risiken oder unkontrolliertes Wanderverhalten. Durch den technologischen Fortschritt ist es möglich geeignete Helfer (Crowd Worker) zu einem Helfernetz (Participatory Sensing) z...

In this paper, a ground-based SAR interferometry technology was used to monitor major engineering. This technology has been recognized as a powerful tool for terrain monitoring and structural change detecting. Deformation monitoring for large project has been a hot issue among them. According to GBSAR interferometry principle and characteristics of IBIS system, the authors analysis the error so...

Participatory Sensing is a new computing paradigm that aims to turn personal mobile devices into advanced mobile sensing networks. For popular applications, we can expect a huge number of users to both contribute with sensor data and request information from the system. In such scenario, scalability of data processing becomes a major issue. In this paper, we present a system for supporting part...

Lesbian, gay, and bisexual (LGB) individuals are members of a vulnerable group where health disparities have been identified. To gain a better understanding of the LGB college student healthcare experience and its contribution to the healthcare disparities found in LGB population, a community based participatory research (CBPR) approach was used to fill the gap. This paper will outline the CBPR...

The Grid is a heterogeneous collection of resources providing a reliable admittance to all of the users thus enabling scalable virtual organizations for resource sharing between the geographically distributed communities. Grid monitoring involves the monitoring of the available resources and the network. The grid resources may dynamically join and leave that leads to monitoring of resources a m...

Feminist attempts to empower women within their own cultural traditions have employed two broad strategies: authentic choice and participation. This paper argues that the methodological problems that beset the authentic choice strategy tell in favour of the participation approach. However, proponents of the participation strategy have failed to pay sufficient attention to the background conditi...
