@article {9998, title = {Examining Open Innovation in Science (OIS): What Open Innovation can and cannot offer the science of science}, journal = {Innovation: Organization \& Management}, year = {2021}, abstract = {

Scholars across disciplines increasingly hear calls for more open and collaborative approaches to scientific research. The concept of Open Innovation in Science (OIS) provides a framework that integrates dispersed research efforts aiming to understand the antecedents, contingencies, and consequences of applying open and collaborative research practices. While the OIS framework has already been taken up by science of science scholars, its conceptual underpinnings require further specification. In this essay, we critically examine the OIS concept and bring to light two key aspects: 1) how OIS builds upon Open Innovation (OI) research by adopting its attention to boundary-crossing knowledge flows and by adapting other concepts developed and researched in OI to the science context as exemplified by two OIS cases in the area of research funding; 2) how OIS conceptualises knowledge flows across boundaries. While OI typically focuses on well-defined organizational boundaries, we argue that blurry and even invisible boundaries between communities of practice may more strongly constrain flows of knowledge related to openness and collaboration in science. Given the uptake of this concept, this essay brings needed clarity to the meaning of OIS, which has no particular normative orientation toward a close coupling between science and industry. We end by outlining the essay{\textquoteright}s contributions to OI and the science of science, as well as to science practitioners.

Prior research on participation in FLOSS development has focused mainly on factors at the individual and/or project levels. In this research, we focus on task characteristics and explore their impacts on participation in FLOSS development tasks. Analyzing tasks from five projects in two categories, we find differences in participation related to different task triggers and task topics. Further, our results suggest the mediating role of number of participants in the relationship between task characteristics and the number of messages and the moderating role of project type in the relationships between task characteristics and the number of participants.

FLOSS teams are an extreme example of distributed teams, prominent in software development. At the core of distributed team success is team decision-making and execution. The lack formal organizational structures to guide practices and the reliance on asynchronous communication might be expected to make decision making problematic. While there is a paucity of research in how organizations make IS development decisions, the research in FLOSS decision making models is limited. Decision-making literature in FLOSS teams is limited to the investigation of the distribution of decision-making power. Therefore, it is not clear which decision-making theories fit FLOSS context best, or whether novel decision-making models are required. Despite these challenges many FLOSS teams are effective. We adopted a process-based perspective to analyze decision-making in five community-based FLOSS teams. We identified five different decision-making processes, indicating FLOSS teams use multiple processes when making decisions. Decision-making behaviors were stable across projects despite different type of knowledge required. We help fill in the literature gap due to the lack of investigations the extent to which FLOSS decision mechanisms can be explained using classical decision-making theories. Practically, community and company leaders should use these decision processes to infrastructure that fits best with the FLOSS decision-making processes.

There is an exciting natural match between social network analysis methods and the growth of data sources produced by social interactions via information technologies, from online communities to corporate information systems. Information Systems researchers have not been slow to embrace this combination of method and data. Such systems increasingly provide "digital trace data" that provide new research opportunities. Yet digital trace data are substantively different from the survey and interview data for which network analysis measures and interpretations were originally developed. This paper examines ten validity issues associated with the combination of data digital trace data and social network analysis methods, with examples from the IS literature, to provide recommendations for improving the validity of research using this combination.
