    Customers as Predictors of Rent Returns to Innovation and Small Firms – an exploratory study

    No full text
    Small to medium enterprises (SME) are frequently associated with high levels of innovation. However, it is difficult for such firms to fully assess the merits of a particular innovation. This study examined the risk-return profile of future investment in innovation by SME with respect to anticipated ‘rent' or financial returns. A survey of highly innovative SME was undertaken that examined management perceptions of the key strategic influences on rent returns. Regression analysis suggests that the firms' assessment of the rent returns from their innovation may be influenced by the value it is likely to deliver to the customer, the customer's expected use of the innovation to generate new sales and the ease of integrating the new innovation into existing technologies. The findings have implications for how entrepreneurs from early stage ventures are assisted.small business; entrepreneurship; innovation; risk assessment

    The Social Value of Multi-stakeholder Co-operatives: The Case of the CEFF System in Italy

    No full text
    Since 1991 social cooperatives have been conceived by the Italian legislation as mutual-benefit entrepreneurial organizations with a social character. The social objective was nested into the mutualistic structure, while the multi-stakeholder governance and the accumulation of socialized assets made social cooperative similar to more traditional non-profit forms. In 2010, the official ISTAT census of social cooperatives recorded about 10.000 active organizations at the national level. The paper offers an analysis of the structure and development of governance at CEFF, as an example of the emergence of a multi-stakeholder cooperative. By analyzing its evolution over time, we aim at shedding new light on the social nature of cooperation, on the ways in which cooperatives can generate and distribute social value across an integrated (horizontal) value chain by means of networking

    Functional alleles of the flowering time regulator FRIGIDA in the Brassica oleracea genome

    Background Plants adopt different reproductive strategies as an adaptation to growth in a range of climates. In Arabidopsis thaliana FRIGIDA (FRI) confers a vernalization requirement and thus winter annual habit by increasing the expression of the MADS box transcriptional repressor FLOWERING LOCUS C (FLC). Variation at FRI plays a major role in A. thaliana life history strategy, as independent loss-of-function alleles that result in a rapid-cycling habit in different accessions, appear to have evolved many times. The aim of this study was to identify and characterize orthologues of FRI in Brassica oleracea. Results We describe the characterization of FRI from Brassica oleracea and identify the two B. oleracea FRI orthologues (BolC.FRI.a and BolC.FRI.b). These show extensive amino acid conservation in the central and C-terminal regions to FRI from other Brassicaceae, including A. thaliana, but have a diverged N-terminus. The genes map to two of the three regions of B. oleracea chromosomes syntenic to part of A. thaliana chromosome 5 suggesting that one of the FRI copies has been lost since the ancient triplication event that formed the B. oleracea genome. This genomic position is not syntenic with FRI in A. thaliana and comparative analysis revealed a recombination event within the A. thaliana FRI promoter. This relocated A. thaliana FRI to chromosome 4, very close to the nucleolar organizer region, leaving a fragment of FRI in the syntenic location on A. thaliana chromosome 5. Our data show this rearrangement occurred after the divergence from A. lyrata. We explored the allelic variation at BolC.FRI.a within cultivated B. oleracea germplasm and identified two major alleles, which appear equally functional both to each other and A. thaliana FRI, when expressed as fusions in A. thaliana. Conclusions We identify the two Brassica oleracea FRI genes, one of which we show through A. thaliana complementation experiments is functional, and show their genomic location is not syntenic with A. thaliana FRI due to an ancient recombination event. This has complicated previous association analyses of FRI with variation in life history strategy in the Brassica genus

    One million quality factor integrated ring resonators in the mid-infrared

    No full text
    We report ring resonators on a silicon germanium on silicon platform operating in the mid-infrared wavelength range around 3.5–4.6 µm with quality factors reaching up to one million. Advances in fabrication technology enable us to demonstrate such high Q-factors, which put silicon germanium at the forefront of mid-infrared integrated photonic platforms. The achievement of high Q is attested by the observation of degeneracy lifting between clockwise (CW) and counter-clockwise (CCW) resonances, as well as optical bistability due to an efficient power buildup in the rings.Marko Perestjuk, Rémi Armand, Miguel Gerardo Sandoval Campos, Lamine Ferhat, Vincent Reboud, Nicolas Bresson, Jean-Michel Hartmann, Vincent Mathieu, Guanghui Ren, Andreas Boes, Arnan Mitchell, Christelle Monat, Christian Grille

    EOS -- A Software for Flavor Physics Phenomenology

    No full text
    I present EOS, an open-source software dedicated to a variety of tasks in the processing of flavor physics observables. EOS is written in C++ and offers both a C++ and a Python interface. It is developed for three main tasks, the production of theoretical predictions for flavor physics observables; the inference of theoretical parameters from an extensible database of likelihoods; and the production of Monte Carlo samples of flavor processes for sensitivity studies.Comment: 9 pages, 4 figure
