Sintesi	Quadruple Helix analysis extends the Triple Helix of university-industry-government relations by adding a fourth helix—the media-based and culture-based public, civil society, and users—as a constitutive actor in innovation. It frames innovation as a 'Mode 3' fractal ecosystem in which knowledge is co-produced across multiple spheres, and it situates this within a broader N-tuple generalisation that can add further helices such as the natural environment in the Quintuple Helix.	Technological Innovation Systems (TIS) analysis studies the emergence, growth, and performance of a specific technology by treating it as a system of actors, networks, and institutions that interact to generate, diffuse, and use that technology. Building on the systems-of-innovation tradition, the influential scheme of Bergek and colleagues combines a structural account of the system's components with a functional analysis of the key processes—or functions—that an innovation system must perform, then compares achieved with desired functionality to diagnose inducement and blocking mechanisms and derive policy.
