The study revealed that when performing activities, researchers were motivated by the desire to share scholarship, feel competent, feel a sense of enjoyment, improve their status, and build ties with other members of the community. Moreover, when researchers performed activities that directly benefited other members of a RIMS, they assigned higher priorities to intrinsic motivations, such as perceived self-efficacy, enjoyment, and building community ties. Furthermore, researchers at different stages of their academic careers and from different disciplines ranked some RIM motivations differently. For the RIMS profile maintenance activity, junior researchers enjoyed and were motivated by the desire to support their evaluations more than were senior researchers. In addition, postdocs were more influenced by external pressure than were senior researchers. Regarding discipline, researchers from engineering had higher priorities for the Support Evaluation and Quality of Recommendations scales than did humanities and social sciences researchers, respectively. For the question-answering activity, students were more motivated by the desire to establish community ties than were full professors.
