	abstract = {Open projects aimed at creating new knowledge (also known as online communities of creation) are increasingly central in the production of new and innovative knowledge. In our research study, we are interested in the impact of initial group characteristics on the quality of the output. We studied in particular Wikipedia in different three languages: Arabic, Romanian and Thai. Our results confirm the importance of the initial project group. We found a positive impact of a large initial group formed by  members with an intermediate level of  diversity in the focus of their editing but having an equal and lower level of longevity.},

	abstract = {<p>The explosion of data available from online systems such as social media is creating a wealth of trace data, that is, data that record evidence of human activity. The volume of data available offers great potential to advance social and behavioural science research. However, the data are of a very different kind than more conventional social and behavioural science data, posing challenges to use. This paper adopts a data framework from Earth Observation science and applies it to trace data to identify possible issues in analyzing trace data. Application of the framework also reveals issues for sharing and reusing data.</p>},

The theoretical background of the paper is based on the technological innovation literature. We choose to focus on the open ERP case, as it is considered as a promising innovation for firms {\textendash} especially medium firms - but open ERP also faces numerous challenges. The paper provides a framework and a method for investigation that has to be implemented.},

	abstract = {Extensive research has been conducted over the past years to improve our understanding of sustainability conditions for large-scale collaborative projects, especially from an economic and governance perspective. However, the influence of recruitment and retention of participants in these projects has received comparatively less attention from researchers. Nevertheless, these concerns are significant for practitioners, especially regarding the apparently decreasing ability of the main open online projects to attract and retain new contributors. A possible explanation for this decrease is that those projects have simply reached a mature state of development. Marwell and Oliver (1993) and Oliver, Marwell, and Teixeira (1985) note that, at the initial stage in collective projects, participants are few and efforts are costly; in the diffusion phase, the number of participants grows, as their efforts are rewarding; and in the mature phase, some inefficiency may appear as the number of contributors is greater than required for the work.

In this article, we examine this possibility. We use original data from 36 Wikipedias in different languages to compare their efficiency in recruiting participants. We chose Wikipedia because the different language projects are at different states of development, but are quite comparable on the other aspects, providing a test of the impact of development on efficiency. Results confirm that most of the largest Wikipedias seem to be characterized by a reduced return to scale. As a result, we can draw interesting conclusions that can be useful for practitioners, facilitators, and managers of collaborative projects in order to identify key factors potentially influencing the adequate development of their communities over the medium-to-long term.},
