Underwater sensor networking is generally regarded as an emerging technology to conduct oceanic exploration and research in an automated and effective manner. As underwater operations become more sophisticated, there is an increasing demand for real-time video streaming. However, real-time video streaming requires high bandwidth as well as low latency.(More)
As a new paradigm of online communities, microfinance sites such as Kiva.org have attracted much public attention. To understand lender motivations on Kiva, we classify the lenders' self-stated motivations into ten categories with human coders and machine learning based classifiers. We employ text classifiers using lexical features, along with social(More)
Clara.io is a cloud and browser-based full featured 3D content creation tool that enables collaborative modelling, animation, simulation and rendering for independent and studio-affiliated artists. Our tool democratizes access to technology by making professional grade content creation capabilities and features accessible to all with internet access at a(More)
We investigate the effects of team competition on pro-social lending activity on Kiva.org, the first microlending website to match lenders with entrepreneurs in developing countries. Using naturally occurring field data, we find that lenders who join teams contribute 1.2 more loans per month than those who do not. Furthermore, teams differ in activity(More)
Analytical cytometry has significant potential beyond cellular analysis. The inherent capability of flow cytometers to efficiently discriminate between uniformly sized particles based on their intrinsic properties provides the foundation for multiplex bead assays. The technology can be exploited in designing immunoassays, Western blot-like antibody assays,(More)
Procurement auctions carry substantial risk when the value of the project is highly uncertain and known only to insiders. This paper reports the results from a series of experiments comparing the performance of three auction formats in such complex and risky settings. In the experiment, every bidder knows the private value for the project but only a single(More)
49 networks provides valuable data, including water temperature, salinity, fish population, the ebb and flow of the tide;the information helps in addressing issues such as the effect of human activities on underwater ecosystem and the impact of pollutants on the marine environment. Another promising application of underwater networks is to launch unmanned(More)
This paper reports the results of a large-scale field experiment designed to test the hypothesis that group membership can increase participation and prosocial lending for an online crowdlending community, Kiva. The experiment uses variations on a simple email manipulation to encourage Kiva members to join a lending team, testing which types of team(More)
When does a common group identity improve efficiency in coordination games? To answer this question, we propose a group-contingent social preference model and derive conditions under which social identity changes equilibrium selection by changing the potential function. We test our predictions in the minimum effort game in the laboratory under parameter(More)
