Knowledge exchange and the third mission of universities : Introduction: the triple helix and the third mission – Schumpeter revisited

Joseph Schumpeter (1883–1950) is well known as an economist, among other things, for his seminal contribution explaining long-term economic growth in terms of innovation and technological progress. He identified innovation at the heart of upswings in the so-called ‘Kondratiev waves’ that profile socioeconomic development trends over long periods. He saw innovation as a dynamic process of ‘creative destruction’ in which new orders arise with the obliteration of the old. This process he attributed to the entrepreneur – the innovator who, in the Schumpeterian paradigm, would in effect count as a history maker. For all its significance as a landmark in the literature of innovation and economic development, Schumpeter’s contribution falls short of providing a theory of innovation. However, he has left behind a long-standing tradition of innovation studies to grapple with this shortfall. The quest continues in the form of innovation systems and evolutionary theory, in which the Triple Helix features as a strand

The Triple Helix Perspective of Innovation Systems

Alongside the neo-institutional model of networked relations among universities, industries, and governments, the Triple Helix can be provided with a neo-evolutionary interpretation as three selection environments operating upon one another: markets, organizations, and technological opportunities. How are technological innovation systems different from national ones? The three selection environments fulfill social functions: wealth creation, organization control, and organized knowledge production. The main carriers of this system-industry, government, and academia-provide the variation both recursively and by interacting among them under the pressure of competition. Empirical case studies enable us to understand how these evolutionary mechanisms can be expected to operate in historical instance. The model is needed for distinguishing, for example, between trajectories and regimes

Cosmology on Compact and Stable Supergravity Background

We propose a cosmological model of D3-brane universe on compact and stable supergravity background of wrapped D7-branes in type IIB string theory previously argued to be dual to pure N=1 SU(N) gauge theory in four dimensions. A model universe of order Planck size near the UV boundary dynamically flows toward the IR with constant total energy density and accelerating expansion followed by smooth transition to decelerating expansion and collides with the wrapped D7-branes at the IR boundary. The model addresses the horizon and flatness problems with most of the expansion produced during the decelerating expansion phase. The inflationary scenario is used to generate sources of inhomogeneities in the cosmic microwave background radiation and seeds for large scale structure formation from quantum fluctuations which exit the Hubble radius early during the accelerating expansion phase and the model addresses the inhomogeneity problem with red tilt in the power spectrum. We propose that the kinetic energy of the model universe is converted to matter and radiation by the collision followed by formation of baryons that stabilizes the model universe against gravitational force from the background at a finite distance from the IR boundary with the wrapped D7-branes serving as sources of color. Friedmann evolution then takes over with a positive cosmological constant term coming from the remaining potential energy density which is interpreted as dark energy. The magnitude of dark energy density is smaller than the total energy density during the flow by a ratio of the scale factor when the model universe appears in the UV to the scale factor at the moment of collision and stays constant while the matter-radiation density falls during Friedmann expansion.Comment: 30 page
