Asymmetric R&D Alliances and Coopetitive Games

In this paper we show how the study of asymmetric R&D alliances, that are those between young and small firms and large and MNEs firms for knowledge exploration and/or exploitation, requires the adoption of a coopetitive framework which consider both collaboration and competition. We draw upon the literature on asymmetric R&D collaboration and coopetition to propose a mathematical model for the coopetitive games which is particularly suitable for exploring asymmetric R&D alliances.Comment: arXiv admin note: substantial text overlap with arXiv:1106.354

chemical and spectroscopic characterization of insoluble and soluble humic acid fractions at different ph values

Background: Humic acids (HA) are organic molecules with complex structure and function and variable properties. They are insoluble in strongly acid pH conditions. At present, it is not clear how much is the amount of HA in solution at the pH of natural soils nor are known the characteristics of the different soluble fractions and their possible association with the inorganic phase of soil. The scope of this work was to characterize the soluble and insoluble fractions obtained by acidifying Na humate solution at pH values 3, 5, and 7 and to compare these fractions with the HA obtained at pH 1. At each pH, the precipitate and the soluble fractions were separated and characterized by elemental analysis, total acidity and carboxylic group content, infrared, and 13 C NMR and 1 H NMR spectroscopy. Results: The HA fraction insoluble at pH 1 had a high acid group content and aromaticity but a low content of Oand N-containing groups. At pH 3, a fraction with nearly the same characteristics was obtained. At pH 1 and pH 3, the inorganic phase bound to the insoluble humic material was largely constituted by clay minerals and some Al and Fe hydroxides. The soluble fractions at pH values 1 and 3 were very poor and they were composed of a silica gel-like phase associated with polar organic material rich in carboxylic and metal-carboxylate groups. At pH values 5 and 7, only a small fraction of the Na humates precipitated. The fractions remaining in the solution were mainly composed of organic material particularly rich in aromatic and aliphatic groups, while the inorganic phase contained phyllosilicates. The fractions insoluble at pH values 5 and 7 contained a large amount of inorganic material that consisted mainly of phyllosilicates. Conclusions: The soluble fractions obtained at pH values 5 and 7 represent the humic component that in environmental situations would be dissolved in the soil solution. Our findings could be very useful for a more detailed investigation into the way HA influence plant metabolism under environmental-like conditions, both as regards pH conditions and interaction with the mineral fraction

Learning from Patents: An Application of Technology Intelligence in NanotechnologyOrganizational Change and Information Systems

Technology is a strategic asset for an increasing number of firms that nurture their competitiveness through innovation. Accordingly, fostering inno-vation, exploiting technological opportunities and avoiding threats are increas-ingly important issues within their strategies. Firms need to support their deci-sion-making processes by investing in technology intelligence system in order to protect their products from competitors\u2019 aggressive actions or to exploit new emerging technological trajectories. This paper presents some actions that a Technology Intelligence System (TIS) can accommodate, drawing upon patent analysis. The main purpose of patent analysis is to enable firms to monitor and assess technological developments and other areas of concern. Such technology management activities assist firms in evaluating their environment while taking advantage of new emerging technological trends. The methodology is described in detail using an application con-ducted in nanotech patent

REJUVENATING NANOCLUSTERS WITH 'SLEEPING ANCHORS': PRE-ADAPTATION AND LIFE CYCLE

Working paper serie RMT (WPS 10-11) , 28 p.International audienceThis article investigates how anchor firms sustain high tech clusters rejuvenation by means of technological pre-adaptation. Based on evidences are drawn from the comparison of the evolution of two nano-electronics clusters, i.e., Grenoble (France) and Catania (Italy) clusters which are sharing the same anchor tenant firm STMicroelectronics. Cluster rejuvenation comes from pre-adaptation of actors (scientific and technological diversity), competition amongst anchor tenant firms, competition and overlap amongst networks and the mobilization of sleeping anchors tenant organizations to renew actors and technologies. As soon as the process of specialization (asset specificity, network specificity, technology speciation) starts, it is important to stimulate pre-adaptation to avoid lock-in of the cluster on one technological trajector

University technology transfer office business models: One size does not fit all

Technology transfer processes enable universities to increase their positive impact on society by pursuing their entrepreneurial mission in several ways. By analyzing quantitative and qualitative data collected in a longitudinal dataset of 60 U.S. universities during the period 2002-2012, this article identifies four types of technology transfer business models that may generate economic and non-economic linkages that need to be evaluated. Findings reveal that business models that leverage high-quality research (i.e., catalyst) and startup creation (i.e., orchestrator of local buzz) are associated with higher economic performance. This study contributes to the emergent literature on university business models and provides suggestions to policymakers to incorporate a business model typology in university evaluation programs

Disabilities and Accessible Tourism: Recent Development and Future Directions in Management Studies

This chapter uses bibliometrics and topic modeling to explore the accessible tourism research domain structure and builds on this result to adjust its scope and applications in management fields. Visualization and co-citation analysis reveal the theoretical roots, the field’s “invisible colleges,” and research directions. Additionally, topic modeling is used to explore the constructs’ key themes and applications. We find evidence of commonalities and polarizing differences among understandings across this research domain, suggesting opportunities and challenges for future research
