Innovation on Open Digital Platforms: Simulating the Effect of Developer Strategies on the Interplay Between Platform Complexity and Performance
Speaker:
Sabine Brunswicker - Associate Professor and Director, Research Center for Open Digital Innovation, Purdue University.
Talk Abstract:
Innovation and production has become increasingly open and distributed phenomenon. Over the last year, platforms have established themselves as the primary model for organizing the development and distribution of digital “apps–. Google Android, iPhone iOS, or Salesforce.com are just a few of many examples. The apps offered on such platforms range from truly novel offerings along with apps presenting incremental advantages over previous versions. This talk presents the results of a recently completed study that is focused on how the platform design, and in particular the complexity of the platform's architecture shapes the performance of different developer behaviors, that are either focused on more incremental or radical design choices. Drawing upon the literature on search and aspirations, the study develops an NK simulation model to represents the developers' iterative app development process, during which the developer pays attention to information on the performance of others' and their own prior app performance. The results from this simulation unpack the effect of different developer strategies on the interplay between platform complexity and platform performance. It discovers several unexpected relationships, such as that platforms with upward striving developers with high aspiration points perform worse under conditions of highly complex platforms. The study results contribute to platform design theory by offering a set of propositions about the relationship between platform complexity, developer profiles, and platform performance. The findings also allow platform owners to revisit their current platform design in order to improve their platform's performance. At the end of the talk, I will provide an overview of ongoing empirical quasi-experiments on open data application development intended to advance our understanding of how platform design can support application developer in re-use to increase developer and platform performance.

WED@NICO SEMINAR: Rosemary Braun, Northwestern University "The Scale of Life"

Speaker:
Rosemary Braun, Associate Professor, Department of Molecular Biosciences, Northwestern University
Title:
The Scale of Life
Abstract:
Living systems exhibit surprising and beautiful self-organization at all scales. At the atomic level, proteins self-assemble into macromolecular complexes. The function of these machines is orchestrated within the cell by regulatory networks, whose activity is in turn dictated by, and coordinated with, the cells environment. This coordination takes place across large spans of space and time: the size and lifetime of organisms as large as the blue whale. Populations and ecosystems of many organisms in turn exhibit remarkable emergent dynamics. Today, advances in single-cell assays enable us to probe the molecular state of every cell in a sample in high-dimensional detail. But is this the correct scale at which to probe living systems? What can we learn from this data, and how can we abstract from the microscopic details to macroscopic phenotypes? In this talk, I will discuss some of our recent work bridging the cell and tissue/organism scales, and discuss some challenges and opportunities for the future.
Speaker Bio:
Rosemary Braun is an Associate Professor of Molecular Biosciences, Applied Mathematics [ESAM], and Physics at Northwestern University. A theoretical physicist by training, she earned her PhD in Physics from the University of Illinois, followed by a Masters in Biostatistics from Johns Hopkins University. She completed her postdoctoral training at the National Cancer Institute (NIH) before joining Northwestern as a faculty member. Today, she works at the intersection of statistics, mathematics, and biology to develop computational tools for analyzing high-dimensional data. In addition to her Northwestern affiliations, she is also Associate Director of the National Institute for Theory and Mathematics in Biology, as well as external faculty of the Santa Fe Institute.
