We focus on the innovation “problem” as the central unit of analysis, arguing for a match between problem types and governance forms, which vary from open to closed and which support alternative forms of solution search. In all, the goal of this paper is to provide a comparative framework...

Bacterial σI factors of the σ70-family are widespread in Bacilli and Clostridia and are involved in the heat shock response, iron metabolism, virulence, and carbohydrate sensing. A multiplicity of σI paralogues in some cellulolytic bacteria have been
2 O Open Versus Closed Systems Learning Objectives Upon completion of this chapter, students should be able to do the following: ! Define closed-system models—scientific management, administrative management, and bureaucratic management ! Define open-system models—total quality management model and ...

2.2 Data analysis Throughout our initial literature review, we began to note that themes of MOOC presence were emerging. We categorized the themes adhering to the theoretical framework developed by Garrison and colleagues, which emphasizes social presence, teaching presence, and cognitive presence in ...
Due to the very complex nature of networked systems and the large number of variables defining their states, it is not possible to consider all events in the set E and obtain a closed-form expression for R, even if all design parameters are made homogeneous across nodes, links, and time....
