The evolution of the innovation network and the technological system in a standard developing organization. The example of cellular telecommunications

Standard developing organizations (SDOs) are voluntary inter-organizational collaborations with the goal to develop jointly compatibility standards for complex modular technological systems. This dissertation examines the evolution of the innovation network and technological system in a SDO with the perspective of complementing micro and macro level. The dissertation is rooted in the multidisciplinary complex system theory and draws on a broad range of literature from management, sociology, biology and physics with the common theme of bipartite network analysis. The innovation network is conceptualized as a bipartite network with ties between organizations and innovations to which they contribute. I show that technical capital, resources in the SDO and their match between organization and innovation, rather than social capital, network position, drive the tie formation in the innovation network. To answer the question of emerging order in an innovation ecology without formal hierarchy I borrow from the literature of ecological mutualistic networks. I show that a nested order emerges based on a parsimonious process of matching resources, that leads to a rather stable system over more than ten years. The evolution of the technological system in the SDO environment departs from the established life cycle model and is best described by a life spiral model with continuously increasing system performance rather than punctuated equilibria. The key distinction to market-based technological evolution is the coordinated and designed development process within the SDO, that allows to introduce new services and change core parts of the system based on architectural knowledge. As a consequence the development process follows a gradual change model with changing tempo. Furthermore the evolution is characterized by simultaneity of innovation types that identifies the SDO as ambidextrous organization with separation of exploitation and exploration on project level. The research context is Third Generation Partnership Project (3GPP) in the cellular telecommunications industry with data from 1992 to 2011.Ph.

Close encounters with the virtual kind: Defining a human-virtual agent coexistence framework

Virtual agent research has evolved into a substantial body of work, albeit one with a fragmented structure and overlapping, and at times inconsistent, definitions and results. The current paper presents a computational literature review of 1865 academic journal publications and conference proceedings from 1995 to 2022 using Latent Dirichlet Allocation to understand the publication trends in the field, its intellectual structure, and how topics within virtual agent research have evolved and relate to each other. Our results point to a model of 16 topics as best representing the current state of the research landscape. We present descriptions of these topics, as well as topic dynamics and networks, in order to provide a clear picture of the current state of the field. We then organise these topics into a Human-Virtual Agent Coexistence Framework, identifying current trends and opportunities for future research

The changing landscape of JIBS authorship

International audienceIn this study, we examine the landscape of JIBS authorship over time to assess: (1) the accessibility of JIBS to new contributors, and (2) the diversity of authors contributing to JIBS. Our analysis of author data from 1972 to 2014 shows that JIBS is becoming more accessible, as indicated by the high and sustained proportion of first-time contributors to the journal. This is also evident from the recent decline in the share of authors with multiple past JIBS publications. With regard to diversity, our findings show that JIBS has a much wider geographic scope of authors on its landscape in comparison to previous decades. This may be attributed partly to increasing travel and communication in scholarly communities, and partly to the increased migration of scholars in the recent decades. Our analysis of migration patterns of JIBS authors suggests that about 51 % of prominent international business scholars are employed outside their country of birth. Of the 49 % employed in their country of birth, 12 % are return migrants. In our sample, China, South Korea and Canada have the highest number of returnees. The USA, the UK, Germany, the Netherlands and China have the highest number of natives, whose country of birth, country of PhD-granting institution and country of university affiliation are identical
