A Life Cycle Perspective On Online Community Success, Alicia Iriberri '06, Gondy Leroy
A Life Cycle Perspective On Online Community Success, Alicia Iriberri '06, Gondy Leroy
CGU Faculty Publications and Research
Using the information systems lifecycle as a unifying framework, we review online communities research and propose a sequence for incorporating success conditions during initiation and development to increase their chances of becoming a successful community, one in which members participate actively and develop lasting relationships. Online communities evolve following distinctive lifecycle stages and recommendations for success are more or less relevant depending on the developmental stage of the online community. In addition, the goal of the online community under study determines the components to include in the development of a successful online community. Online community builders and researchers will benefit …

On The Computational Complexity Of The Reticulate Cophylogeny Reconstruction Problem, Ran Libeskind-Hadas, Michael A. Charleston
All HMC Faculty Publications and Research
The cophylogeny reconstruction problem is that of finding minimal cost explanations of differences between evolutionary histories of ecologically linked groups of biological organisms. We present a proof that shows that the general problem of reconciling evolutionary histories is NP-complete and provide a sharp boundary where this intractability begins. We also show that a related problem, that of finding Pareto optimal solutions, is NP-hard. As a byproduct of our results, we give a framework by which meta-heuristics can be applied to find good solutions to this problem.
Persuading Consumers To Form Precise Search Engine Queries, Gondy Leroy
Persuading Consumers To Form Precise Search Engine Queries, Gondy Leroy
CGU Faculty Publications and Research
Today’s search engines provide a single textbox for searching. This input method has not changed in decades and, as a result, consumer search behaviour has not changed either: few and imprecise keywords are used. Especially with health information, where incorrect information may lead to unwise decisions, it would be beneficial if consumers could search more precisely. We evaluated a new user interface that supports more precise searching by using query diagrams. In a controlled user study, using paper-based prototypes, we compared searching with a Google interface with drawing new or modifying template diagrams. We evaluated consumer willingness and ability to …
