Micro evidence for sources of innovation in European countries
2012
This paper investigates sources of product or process innovation, such as investments in research and development, machinery, personnel training and management systems, by examining microdata from eight European countries. We pay particular attention to the effect of research and development in favouring the absorption of new technologies, i.e. the absorptive capacity. Significant positive effects of each source on both product and process innovations are found. Significant evidence of positive absorptive capacity emerges only in firms with low predicted probabilities of introducing innovation.
On the link between urban location and the involvement of knowledge intensive business services firms in collaboration networks
2013
Knowledge intensive business services firms can play a key role in modern economies by linking localized collaboration networks to global knowledge flows, and by actively serving in support of knowledge diffusion across institutional and sectoral divides. The extent to which they do is dependent on the markets, partners and human resources available locally. This paper uses the unique establishment-level innovation data available in Norway to investigate whether location in urban labour market regions influences the geographical scope of collaborative linkages maintained within and outside the realm of clients. It proceeds to consider whether the diversity of partner types used locally, dom…
Ostacoli e determinanti dell’innovazione: un’analisi sulle imprese siciliane di successo
2010
Questo lavoro intende contribuire ad ampliare la precedente indagine Res sull’innovazione in Sicilia, soffermandosi in particolare ad analizzare i principali fattori di ostacolo alla realizzazione di innovazioni. In generale, le nostre elaborazioni mettono in evidenza l'esistenza di elevati livelli di percezione delle barriere territoriali esterne imposte dalle carenze del contesto (infrastrutture, pubblica amministrazione, servizi alle imprese etc.). Tuttavia, le nostre stime fanno emergere l’importanza delle barriere economiche e delle barriere relazionali nel determinare soprattutto le innovazioni di processo. Un altro risultato della ricerca sottolinea l’elevato grado di interdipendenza…
The Rise and Fall of the Oslo School
2007
In 1931 Ragnar Frisch became professor at the University of Oslo. By way of his research, a new study programme and new staff he created the ”Oslo School”, characterised by mathematical modelling, econometrics, economic planning and scepticism towards the market economy. Consequently, detailed state economic planning and governance dominated Norwegian economic policy for three decades after WWII. In the 1970s the School’s dominance came to an end when the belief in competitive markets gained a foothold and the economy had poor performance. As a result a decentralized market economy was reintroduced. However, mathematical modelling and econometrics remain in the core of most economic program…
Social capital formation across space: proximity and trust in European regions
2013
An extensive economics and regional science literature has discussed the importance of social capital for economic growth and development. Yet, what social capital is and how it is formed are elusive issues, which require further investigation. Here, we refer to social capital in terms of “civic” capital and “good culture,” as rephrased by Guiso, Sapienza, and Zingales and Tabellini. The accumulation of this kind of capital allows the emerging of regional informal institutions, which may help explaining differences in regional development. In this article, we take a regional perspective and use exploratory space and space–time methods to assess whether geography, via proximity, contributes…
Exploration of jet substructure using iterative declustering in pp and Pb–Pb collisions at LHC energies
2020
The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at $\sqrt{s}$= 7 TeV and central Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV. Jet substructure of track-based jets is explored via iterative declustering and grooming techniques. We present the measurement of the momentum sharing of two-prong substructure exposed via grooming, the $z_{\rm{g}}$, and its dependence on the opening angle, in both pp and Pb-Pb collisions. We also present the first measurement of the distribution of the number of branches obtained in the iterative declustering of the jet, which is interpreted as the number of its hard splittings. In Pb-Pb collisions, we…
Reporting in Conflict Zones in Pakistan: Risks and Challenges for Fixers
2020
As a backbone of reporting in war and conflicts, fixers offer essential assistance to the foreign correspondent in conflict zones, also in Pakistan. With valuable local knowledge and contacts, fixers can arrange travel to secure entry of foreign correspondents into conflict zones in addition to securing interviews with otherwise unattainable figures, while offering reliable translation services. Pakistani media, despite being one of the largest and most developed in South Asia, remains under the strict control of powerful military establishment and government, while seeming to mirror the overarching government sentiment with a distinct lack of research-based news. Challenging this state of …
Predicting moral attitudes and antisocial behavior in young team sport athletes. A self-determination theory perspective
2019
Identifying the factors associated with prosocial and antisocial behaviors in youth sport may provide evidence to inform interventions aimed at promoting prosocial behaviors and minimizing rule transgressions in young athletes. We investigated relations among social‐contextual factors (e.g., social support), personal motivational factors (e.g., psychological need satisfaction and motivation), young athletes’ attitudes toward prosocial (e.g., keeping winning in proportion) and antisocial (e.g., acceptance of cheating and gamesmanship) behaviors, and their actual rule violations during matches in two samples of athletes. Participants in Sample 1 were young team sport athletes (N = 355) and pa…
Phytoplankton group identification with chemotaxonomic biomarkers: In combination they do better
2023
Chemotaxonomic biomarkers are needed to monitor and evaluate the nutritional quality of phytoplankton communities. The biomolecules produced by different phytoplankton species do not always follow genetic phylogeny. Therefore, we analyzed fatty acids, sterols, and carotenoids from 57 freshwater phytoplankton strains to evaluate the usability of these biomolecules as chemotaxonomic biomarkers. We found 29 fatty acids, 34 sterols, and 26 carotenoids in our samples. The strains were grouped into cryptomonads, cyanobacteria, diatoms, dinoflagellates, golden algae, green algae, and raphidophytes, and the phytoplankton group explained 61%, 54%, and 89% of the variability of fatty acids, sterols, …
Freeze-out radii extracted from three-pion cumulants in pp, p–Pb and Pb–Pb collisions at the LHC
2014
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplicity collisions, two-pion correlations are substantially altered by background correlations, e.g. mini-jets. Such correlations can be suppressed using three-pion cumulant correlations. We present the first measurements of the size of the system at freeze-out extracted from three-pion cumulant correl…
