IPTS WP 4/2012: Research cooperation within and across regional boundaries. Does innovation policy add anything?
No full textThe paper aims to show how policy makers can stimulate firms' cooperation with research organisations in innovation. We argue that the administration of an R&D subsidy can be effective. Furthermore, this should be more so for extra-regional than intra-regional cooperation. The firms' propensity to extend cooperation across the region is assumed to increase with the amount of support. However, the support must overcome a threshold, for firms to cover the fixed costs of distant interactions. These research hypotheses are tested with respect to a sample of firms in a region of Italy. Propensity score matching is applied to identify the impact of the subsidy receipt. A generalised propensity score technique is employed to investigate the effect of an increasing amount of support. All the hypotheses are not rejected. Firms' cooperation is policy sensitive, but the size of the support is crucial for its effects.JRC.J.2 - Knowledge for Growt
The “green-impact” of the open innovation mode. Bridging knowledge sourcing and absorptive capacity for environmental innovations
No full textThis policy brief presents recent results on
the impact that an open innovation mode
has on European firms' environmental
innovations. New evidence drawn from the
CIS suggests that knowledge sourcing can
increase the environmental innovation
performance of firms. However, the way
firms search for external knowledge and
work to absorb it can lead them to different
results, depending on whether they are
involved in the adoption of an ecoinnovation
or the extension of their ecoinnovation
portfolio. Drawing on these
results, policy implications for the European
Research and Innovation Agenda are
discussed

Research cooperation within and across regional boundaries. Does innovation policy add something?
No full textTrabajo presentado a la International Conference on “The Governance of a Complex World”, celebrada en Nice (Francia) del 1 al 3 de Noviembre de 2012.The paper aims to show how policy makers can stimulate firms' cooperation with research organisations in innovation.

The open eco-innovation mode. An empirical investigation of eleven European countries
No full textThis paper deals with the open innovation mode in the environmental realm and investigates the effects
that knowledge sourcing has on the environmental innovations (EIs) of firms. Using the Community Innovation
Survey (CIS) 2006–2008, we refer to the firm’s probability of both introducing an EI and extending
the number of EI-typologies adopted. We estimate the impact of the ‘depth’ and ‘breadth’ of knowledge
sourcing. In addition, we test for the moderating role of the firm’s absorptive capacity. Knowledge
sourcing has a positive impact on both types of EI-performance. However, a broad sourcing strategy
reveals a threshold above which the propensity to introduce an EI diminishes. Cognitive constraints in
processing knowledge inputs that are too diverse may explain this result. Absorptive capacity generally
helps firms to turn broadly sourced external knowledge into EI. However, internal innovation capabilities
and knowledge socialization mechanisms seem to diminish the EI impact of knowledge sourced
through deep external interactions. The possibility of mismatches between the management of internal
and external knowledge, and of problems in distributing the decision-makers’ attention between the
two, may explain this result
Distributed k-core decomposition
No full textAmong the novel metrics used to study the relative importance of nodes in complex networks, k-core decomposition has found a number of applications in areas as diverse as sociology, proteinomics, graph visualization, and distributed system analysis and design. This paper proposes new distributed algorithms for the computation of the k-core decomposition of a network, with the purpose of (i) enabling the run-time computation of k-cores in "live" distributed systems and (ii) allowing the decomposition, over a set of connected machines, of very large graphs, that cannot be hosted in a single machine. Lower bounds on the algorithms complexity are given, and an exhaustive experimental analysis on real-world graphs is provided
Does external knowledge affect environmental innovations? An empirical investigation on eleven European countries
No full textTrabajo presentado al 8th European Meeting on Applied Evolutionary Economics celebrado en Sophia Antipolis (Francia) del 10 al 12 de Junio de 2013.This paper investigates the effects that knowledge sources external to the firm have on its environmental innovations (EIs). Using the CIS 2006-2008, we refer to both the probability to introduce an EI and the number of EI-typologies adopted by firms. We estimate the impact of the “depth” and “breadth” of knowledge sourcing. In addition, we test for the moderating role of the firm's absorptive capacity. In general, knowledge sourcing has a positive impact on both types of EI-performance. However, a broad sourcing strategy reveals a threshold, over which the propensity to introduce an EI diminishes. Cognitive constraints in processing knowledge inputs that are too diverse could explain this result. Absorptive capacity generally helps firms in turning broadly sourced external knowledge into EI. Conversely, internal innovation capabilities and knowledge socialization mechanisms seem to diminish the EI impact of knowledge sourced through intense external interactions. The possibility of mismatches between internal and external knowledge and problems in distributing the decision-makers’ attention between the two could explain this result.Peer Reviewe
ETSCH: Partition-Centric Graph Processing
No full textThis paper presents ETSCH, a novel paradigm for processing large graphs. ETSCH departs from the vertex-based approach of BSP frameworks like PREGEL in two ways: first, the units of computation are not the vertices, but rather a collection of subgraphs, obtained by partitioning the input graph, second, the subgraphs are obtained through an edge-partitioning algorithm, in which edges, rather than vertices, are subdivided into disjoint subsets Global computations over the graph are then easily expressed using classical centralized algorithms executed on each of the partitions, with the only additional burden of specifying simple reconciliation procedures when vertices are replicated in multiple computing nodes. The ETSCH paradigm has been implemented both on top of existing frameworks like HADOOP, SPARK, as a stand-alone service based on AKKA, a toolkit for building distributed message-driven applications. When considering problems like single-source shortest path, PageRank, our experiments show that solutions based on ETSCH/HADOOP, ETSCH/SPARK already outperform the standard solutions to the same problems in HADOOP, SPARK, respectively. But it is our AKKA implementation that really shines: the execution time on graphs with millions of edges falls down from from thousands of seconds (ETSCH/HADOOP) to tens of seconds (ETSCH/SPARK) to seconds (ETSCH/AKKA), while easily scaling to graphs with billions of edges. ETSCH/AKKA is also faster than other partition-centric frameworks like BLOGEL, GPS
