We explore contextual and dispositional correlates of the motivation to contribute to open source initiatives. We examine how the context of the open source project, and the personal values of contributors , are related to the types of motivations for contributing. A web-based survey was administered to 300 contributors in two prominent open source(More)
the success of Wikipedia demonstrates that self-organizing production communities can produce high-quality information-based products. research on Wikipedia has proceeded largely atheoretically, focusing on (1) the diversity in members’ knowledge bases as a determinant of Wikipedia’s content quality, (2) the task-related conflicts that occur during the(More)
Digital citizen science offers a low-cost way to strengthen the scientific infrastructure, and engage members of the public in science. It is based on two pillars:(1)a technological pillar, which involves developing computer systems to manage large amounts of distributed resources, and (2) a motivational pillar, which involves attracting and retaining(More)
Online citizen science offers a low-cost way to strengthen the infrastructure for scientific research and engage members of the public in science. As the sustainability of online citizen science projects depends on volunteers who contribute their skills, time, and energy, the objective of this study is to investigate effects of motivational factors on the(More)
We propose and test a framework of the antecedents of contribution in two technology-mediated citizen science projects, with different degrees of task granularity. Comparing earlier findings on the motivations of volunteers in a web-based image analysis project (high granularity), with new findings on the motivations of volunteers in a volunteer computing(More)
In this paper we extend earlier work on the role of the personality trait of resistance to change (RTC) in the adoption of digital libraries. We present an integrative study, drawing on a number of research streams, including IT adoption, social psychology, and digital-library acceptance. Using structural equation modeling, we confirm RTC as a direct(More)
In recent years we have witnessed a significant growth of social-computing communities—online services in which users share information in various forms. As content contributions from participants are critical to the viability of these communities, it is important to understand what drives users to participate and share information with others in such(More)
