Inter-firm inventor mobility and the role of co-inventor networks in producing high-impact innovation

Inter-firm mobility of inventors is a major source of embodied knowledge transfer and receiving firms enjoy additional benefits from the collaboration networks of mobile inventors. However, there is still limited understanding on how the firm can maximize the impact of incoming inventors and what structure of co-inventor networks is the most beneficial for that. To answer this question, we construct a weighted and time-decayed co-inventor network from all IT-related patents in the harmonized OECD PATSTAT 1977-2010 database and analyze events of inter-firm inventor mobility. We look at the future impact of firm innovation and isolate the effect of mobile inventors' network characteristics from the characteristics of the collaboration network in the receiving firm. Our results imply that high-impact innovations are produced if the firm hires broker inventors who have diverse networks and thus has the potential to channel a wide pool of knowledge into the firm. We find evidence that cohesive networks within the firm, measured by small world characteristics, exaggerate the effect of incoming brokers and high-impact inventors

Brokering the core and the periphery: Creative success and collaboration networks in the film industry

In collaboration-based creative industries, such as film production, creators in the network core enjoy prestige and legitimacy that are key for creative success. However, core creators are challenged to maintain diverse access to new ideas or alternative views that often emerge from the network periphery. In this paper, we demonstrate that creators in the network core can increase the probability of their creative success by brokering peripheral collaborators to the core. The argument is tested on a dynamic collaboration network of movie creators constructed from a unique dataset of Hungarian feature films for the 1990-2009 period. We propose a new way to capture brokers' role in core/periphery networks and provide evidence that being in the core and at the same time bridging between the core and the periphery of the network significantly increases the likelihood of award winning

Characterization of the Site‐Specific Acid‐Base Equilibria of 3‐Nitrotyrosine

The complete macro- and microequilibrium analyses of 3-nitrotyrosine, a biomarker of oxidative stressdamage, are presented for the first time. The protonation macroconstants were determined by1H-NMR-pHtitration, while microconstants were elucidated by a combination of deductive and NMR methods, in whichproperties of the methyl ester derivative as an auxiliary compound were also studied. Combination of the NMR-pH characterization of the title and auxiliary compounds and the pair-interactivity parameters of 3-iodotyrosineprovided the sufficient system to evaluate all the microconstants. NMR-pH profiles, macroscopic and microscopicprotonation schemes, and species-specific distribution diagrams are included. The phenolate basicity of 3-nitrotyrosine is 500 times below that of tyrosine, and it is even lower than that of 3-iodotyrosine. Thisphenomenon can be explained by the stronger electron withdrawing and the negative mesomeric effect of thenitro group. Based on our results, 89 % of the phenolic OH groups are deprotonated in 3-NT molecules at the pHof the blood plasma
