Transferring Social Capital Across Knowledge Domains: The Case of Nanoscience and Nanotechnology
No full textNew ‘networked’ modes of innovation increasingly emphasize the need for organizations to rely on external relationships in R&D and bring in knowledge and competences from domains outside the commercial realm. This has created opportunities for individual knowledge workers to function as critical conduits of knowledge and resources across domains of knowledge that are institutionally distant but interdependent - as the science and technology - for the knowledge creation process. The present paper explores how individual researchers accumulate and transfer social capital across these domains to generate novel knowhow. We specifically focus the attention on the structural dimension of social capital. Our empirical analysis is based on a 20-year longitudinal sample of authors, inventors, and author-inventors involved in the emerging field of nanoscience and nanotechnology

Scheurvorming in jong beton: Onderzoek biedt nieuwe inzichten in de spanningsrelaxatie bij jong beton
No full textBeton is tijdens het verharden onderhevig aan thermische en autogene vervormingen. Wanneer deze worden verhinderd, resulteert dit in spanningen en het risico op scheurvorming, mede afhankelijk van relaxatie. Aan de TU Delft is onderzoek gedaan naar het effect van spanningsrelaxatie op scheurvorming in jong beton. In tegenstelling tot de verwachtingen, blijkt dat spanningsrelaxatie in de eerste twee dagen juist resulteert in een verhoogd risico op scheurvorming bij bepaalde constructies met verhinderde vervorming. Ook blijkt dat autogene zwelling daarbij een significante rol speelt, die tot op heden in de norm buiten beschouwing wordt gelaten.Materials and EnvironmentConcrete Structure

After the life sciences strategy: managing science-based R&D collaborations
No full textThis event looked at the challenges of managing academic collaborations in commercial R&D projects in UK life sciences. Speaking at this event were CSOs of some of the UK's leading therapeutic biotechnology firms including Astex Pharmaceuticals, ReNeuron, Summit, and Vernalis. Further perspectives were presented by David T Phillips, Partner at SR One (the corporate venture capital arm of GlaxoSmithKline) and Dave Tapolczay, CEO of MRC Technology. The event was hosted by Louise Marston of NESTA and Simcha Jong, Lecturer in Management Science and Innovation from UCL who discussed his UK Innovation Research Initiative project on the international competitive position of UK R&D-intensive life sciences firms. It was followed by short presentations from the speakers about their experiences with organising science-intensive R&D projects. Support for this event is acknowledged from the Innovation Research Initiative program that is jointly funded by BIS, the TSB, the ESRC, and NESTA

The ideological sources of North Korean regime resiliency during Kim Jong-Un's leadership
No full textIn this thesis, the author observes and analyzes how ideological discourse contributes to the\ud
resiliency of the North Korean regime during the leadership of Kim Jong-un. He utilizes an\ud
integrated quantitative and qualitative method to perform a content analysis of editorials\ud
published in Rodong Sinmun, the official news publication of the ruling Korean Workers???\ud
Party, between 2011 and 2013. In particular, he observes predication, presupposition, and\ud
subject-object placement in sentence structure. The author finds that the party uses\ud
numerous forms of discourse ??? Confucian, corporatist, strong-nation, and resistance ??? to\ud
frame relationships shared by entities internal to North Korea. The party constructs political\ud
reality for subjects by binding all together ??? the Kim family leaders, the party, the army, the\ud
people, and other internal entities. In so doing, the party also prevents realization of\ud
alternative political reality. Surprisingly, resistance discourse is generally limited in usage and\ud
development through the two years of observation; however, it is more effectively used and\ud
developed during a certain period in 2013, the year in which Kim Jong-un becomes a greater\ud
discursive presence than his father and former North Korean leader, Kim Jong-il. The\ud
author reveals that the process of power consolidation for Kim Jong-un is not yet over
How Organizational Structures in Science Shape Spin-Off Firms: The Biochemistry Departments of Berkeley, Stanford, and Ucsf and the Birth of the Biotech Industry
No full textThis article examines how the organizational capabilities of academic spin-off firms in new industries are shaped by the organization of the research communities in universities from which these spin-off firms emerge. Contrasting the organization of research in the biochemistry departments of the University of California at Berkeley (Berkeley), Stanford University (Stanford), and the University of California at San Francisco (UCSF) and key biotech firms spun-off from these departments, this article attempts to explain the central role UCSF scientists played in comparison with their Berkeley and Stanford counterparts, in the formation and development of the biotech industry in the San Francisco region during the late 1970s and early 1980s. It is demonstrated how the research environment at UCSF during this period positioned UCSF scientists comparatively well to identify in the context of their research new technological opportunities in therapeutic product markets and pursue these opportunities in the industrial research environment of the biotech industry. Finally, drawing parallels between this study on the role of UCSF in the formation of the San Francisco biotech industry and other studies on the role of Stanford in the formation of the Silicon Valley high-tech electronics industry, this article attempts to infer some general insights into the institutional dynamics that give rise to new science-based industries
Development of scaling methods for broadband turbulent noise in internal flow devices by means of experiments and CFD
No full textBroadband turbulent noise can lead to fluid-acoustic and fluid-structure interaction and ultimately to mechanical failure of pipe systems. In HVAC (Heating Ventilating and Air Conditioning) systems broadband turbulent noise can radiate outwards where it is a nuisance or even harmful to people. A fast and simple approach for investigating broadband noise is the scaling law approach originally derived by (Nelson & Morfey, 1981) based on pressure drop. Recently this approach is improved by (de Jong & Golliard, 2013) using steady Reynolds Averaged Navier Stokes (RANS) simulations but was only validated using benchmark geometries. In this work experiments are performed on several DIN standard bends as well as on an orifice. Their sound power spectra are successfully scaled. Furthermore the scaling law by (de Jong & Golliard, 2013) is improved by implementing an automated length scale selection.Solid and Fluid MechanicsProcess and EnergyMechanical, Maritime and Materials Engineerin
Detection of the irradiated donor in the LMXBs 4U 1636-536 (=V801 Ara) and 4U 1735-444 (=V926 Sco)
No full textPhase-resolved VLT spectroscopy of the bursting low-mass X-ray binaries 4U 1636-536/V801 Ara and 4U 1735-444/V926 Sco is presented. Doppler images of the N iiiλ4640 Bowen transition reveal compact spots which we attribute to fluorescent emission from the donor star and enable us to define a new set of spectroscopic ephemerides. We measure Kem= 277 ± 22 and 226 ± 22 km s−1 from the N iii spots in V801 Ara and V926 Sco, respectively, which represent strict lower limits to the radial velocity semi-amplitude of the donor stars. Our new ephemerides provide confirmation that light-curve maxima in V801 Ara and likely V926 Sco occur at superior conjunction of the donor star and hence photometric modulation is caused by the visibility of the X-ray heated donor. The velocities of He iiλ4686 and the broad Bowen blend are strongly modulated with the orbital period, with phasing supporting emission dominated by the disc bulge. In addition, a reanalysis of burst oscillations in V801 Ara, using our spectroscopic T0, leads to K1= 90–113 km s−1. We also estimate the K-corrections for all possible disc flaring angles and present the first dynamical constraints on the masses of these X-ray bursters. These are K2= 360 ± 74 km s−1, f(M) = 0.76 ± 0.47 M⊙ and q= 0.21–0.34 for V801 Ara and K2= 298 ± 83 km s−1, f(M) = 0.53 ± 0.44 M⊙ and q= 0.05–0.41 for V926 Sco. Disc flaring angles α≥ 12° and q≃ 0.26–0.34 are favoured for V801 Ara whereas the lack of K1 constraint for V926 Sco prevents tight constraints on this system. Although both binaries seem to have intermediate inclinations, the larger equivalent width of the narrow N iii line in V801 Ara at phase 0.5 relative to phase 0 suggests that it has the higher inclination of the two
