Mechanism design for spatio-temporal request satisfaction in mobile networks
Mobile agents participating in geo-presence-capable crowdsourcing applications should be presumed rational, competitive, and willing to deviate from their routes if given the right incentive. In this paper, we design a mechanism that takes into consideration this rationality for request satisfaction in such applications. We propose the Geo-temporal Request Satisfaction (GRS) problem to be that of finding the optimal assignment of requests with specific spatio-temporal characteristics to competitive mobile agents subject to spatio-temporal constraints. The objective of the GRS problem is to maximize the total profit of the system subject to our rationality assumptions. We define the problem formally, prove that it is NP-Complete, and present a practical solution mechanism, which we prove to be convergent, and which we evaluate experimentally.National Science Foundation (1012798, 0952145, 0820138, 0720604, 0735974
Guidelines Towards Better Participation of Older Adults in Software Development Processes using a new SPIRAL Method and Participatory Approach
This paper presents a new method of engaging older participants in the
process of application and IT solutions development for older adults for
emerging IT and tech startups. A new method called SPIRAL (Support for
Participant Involvement in Rapid and Agile software development Labs) is
proposed which adds both sustainability and flexibility to the development
process with older adults. This method is based on the participatory approach
and user empowerment of older adults with the aid of a bootstrapped Living Lab
concept and it goes beyond well established user-centered and empathic design.
SPIRAL provides strategies for direct involvement of older participants in the
software development processes from the very early stage to support the agile
approach with rapid prototyping, in particular in new and emerging startup
environments with limited capabilities, including time, team and resources
Emerging Opportunities: Monitoring and Evaluation in a Tech-Enabled World
Various trends are impacting on the field of monitoring and evaluation in the area of international development. Resources have become ever more scarce while expectations for what development assistance should achieve are growing. The search for more efficient systems to measure impact is on. Country governments are also working to improve their own capacities for evaluation, and demand is rising from national and community-based organizations for meaningful participation in the evaluation process as well as for greater voice and more accountability from both aid and development agencies and government.These factors, in addition to greater competition for limited resources in the area of international development, are pushing donors, program participants and evaluators themselves to seek more rigorous – and at the same time flexible – systems to monitor and evaluate development and humanitarian interventions.However, many current approaches to M&E are unable to address the changing structure of development assistance and the increasingly complex environment in which it operates. Operational challenges (for example, limited time, insufficient resources and poor data quality) as well as methodological challenges that impact on the quality and timeliness of evaluation exercises have yet to be fully overcome
