Micro-based evidence of EU competitiveness: The CompNet Database. National Bank of Belgium Working Paper No. 253, March 2014

Drawing from confidential firm-level balance sheets in 11 European countries, the paper presents a novel sectoral database of comparable productivity indicators built by members of the Competitiveness Research Network (CompNet) using a newly developed research infrastructure. Beyond aggregate information available from industry statistics of Eurostat or EU KLEMS, the paper provides information on the distribution of firms across several dimensions related to competitiveness, e.g. productivity and size. The database comprises so far 11 countries, with information for 58 sectors over the period 1995-2011. The paper documents the development of the new research infrastructure, the construction of the database, and shows some preliminary results. Among them, it shows that there is large heterogeneity in terms of firm productivity or size within narrowly defined industries in all countries. Productivity, and above all, size distribution are very skewed across countries, with a thick left-tail of low productive firms. Moreover, firms at both ends of the distribution show very different dynamics in terms of productivity and unit labour costs. Within-sector heterogeneity and productivity dispersion are positively correlated to aggregate productivity given the possibility of reallocating resources from less to more productive firms. To this extent, we show how allocative efficiency varies across countries, and more interestingly, over different periods of time. Finally, we apply the new database to illustrate the importance of productivity dispersion to explain aggregate trade results.

A Differentiated, Balanced and Patient Approach? The EU’s Involvement with Georgia’s Secessionist Conflicts beyond the August 2008 War. EU Diplomacy Paper 06/2015.

The August war in 2008 between Russia and Georgia caught the world by surprise but nevertheless brought the European Union (EU) to the forefront of the international efforts to end the hostilities, and the EU became the leading international actor involved with the conflict resolution process. However, in the years following the armed conflict, the conflict resolution process lost pace, and the impact of the EU beyond the immediate aftermath of the August 2008 war has been put into question. By undertaking a qualitative case study, this paper aims to explore to what extent the EU has impacted on the conflict resolution process of Georgia’s secessionist conflicts in 2008-2015. It will argue that the EU’s policies have only to a limited extent impacted on this conflict resolution process, which can be related to the objectives, priorities and time perspectives of the EU’s conflict resolution policies. The EU’s efforts have significantly contributed to the objective of conflict prevention, but the profile of the EU in the field of international conflict management weakened its position in the area of conflict transformation, where the lack of progress in turn limited the EU’s impact in the areas of international conflict management and conflict settlement. The main conclusion put forward is that in order to have a true impact, the EU needs to undertake a differentiated, balanced and patient approach to conflict resolution.

Measuring competitiveness in Europe: resource allocation, granularity and trade. Bruegel Blueprint Series Volume XVIV, January 2016

One of the most important lessons learned during the 2008-09 financial crisis was that the informational toolbox on which policymakers base their decisions about competitiveness became outdated in terms of both data sources and data analysis. The toolbox is particularly outdated when it comes to tapping the potential of micro data for the analysis of competitiveness – a serious problem given that it is firms, rather than countries that compete on global markets.

Tradurre poesia: Tenebra di David Castillo

Proposta di traduzione della prima parte della raccolta di poesie "Tenebra" dell'autore catalano David Castillo. L'elaborato, oltre al commento alla traduzione, propone un'analisi sulla metodologia di traduzione di componimenti poetici: chi può tradurre poesia? Il talento traduttivo può prescindere da quello poetico? Cosa distingue un traduttore da un poeta? Tradurre poesia è un'operazione difficile; più di tutto, è una sfida, non facile da vincere. Quale sia la vittoria, poi, è tutto da vedere. E del resto, se tradurre fosse facile, non sarebbe poi così bello.

Equity crowdfunding: analisi finanziaria della piattaforma Crowdcube

La crescente difficoltà di accesso ai canali tradizionali ha spinto le start-up e le PMI a ricercare soluzioni alternative di finanziamento al fine di trovare le risorse economiche necessarie per la loro crescita e il loro sviluppo. Una nuova opportunità che sta emergendo negli ultimi anni è l’equity-based crowdfunding. La tesi si pone l’obiettivo di ottenere indicazioni sulla profittabilità previsionale delle imprese e dei singoli individui che ricorrono all’equity crowdfunding. Per ricercare queste informazioni è stata svolta un’analisi empirica selezionando un campione di 100 progetti dalla piattaforma britannica Crowdcube. Quella svolta è una analisi finanziaria implementata utilizzando i dati previsionali contenuti nel piano economico-finanziario dei progetti presi come campione.

2C-Cas9: a versatile tool for clonal analysis of gene function

CRISPR/Cas9-mediated targeted mutagenesis allows efficient generation of loss-of-function alleles in zebrafish. To date this technology has been primarily used to generate genetic knockout animals. Nevertheless, the study of the function of certain loci might require tight spatiotemporal control of gene inactivation. Here, we show that tissue-specific gene disruption can be achieved by driving Cas9 expression with the Gal4/UAS system. Furthermore, by combining the Gal4/UAS and Cre/loxP systems, we establish a versatile tool to genetically label mutant cell clones, enabling their phenotypic analysis. Our technique has the potential to be applied to diverse model organisms, enabling tissue-specific loss-of-function and phenotypic characterization of live and fixed tissues.

A detector based on silica fibers for ion beam monitoring in a wide current range

A detector based on doped silica and optical fibers was developed to monitor the profile of particle accelerator beams of intensity ranging from 1 pA to tens of µA. Scintillation light produced in a fiber moving across the beam is measured, giving information on its position, shape and intensity. The detector was tested with a continuous proton beam at the 18 MeV Bern medical cyclotron used for radioisotope production and multi-disciplinary research. For currents from 1 pA to 20 µA, Ce3+ and Sb3+ doped silica fibers were used as sensors. Read out systems based on photodiodes, photomultipliers and solid state photomultipliers were employed. Profiles down to the pA range were measured with this method for the first time. For currents ranging from 1 pA to 3 µA, the integral of the profile was found to be linear with respect to the beam current, which can be measured by this detector with an accuracy of ∼1%. The profile was determined with a spatial resolution of 0.25 mm. For currents ranging from 5 µA to 20 µA, thermal effects affect light yield and transmission, causing distortions of the profile and limitations in monitoring capabilities. For currents higher than ∼1 µA, non doped optical fibers for both producing and transporting scintillation light were also successfully employed.

Bivalirudin for Alternative Anticoagulation in Extracorporeal Membrane Oxygenation: A Systematic Review.

BACKGROUND Extracorporeal membrane oxygenation (ECMO) offers therapeutic options in refractory respiratory and/or cardiac failure. Systemic anticoagulation with heparin is routinely administered. However, in patients with heparin-induced thrombocytopenia or heparin resistance, the direct thrombin inhibitor bivalirudin is a valid option and has been increasingly used for ECMO anticoagulation. We aimed at evaluating its safety and its optimal dosing for ECMO. METHODS Systematic web-based literature search of PubMed and EMBASE performed via National Health Service Library Evidence and manually, updated until January 30, 2016. RESULTS The search revealed 8 publications relevant to the topic (5 case reports). In total, 58 patients (24 pediatrics) were reported (18 received heparin as control groups). Bivalirudin was used with or without loading dose, followed by infusion at different ranges (lowest 0.1-0.2 mg/kg/h without loading dose; highest 0.5 mg/kg/h after loading dose). The strategies for monitoring anticoagulation and optimal targets were dissimilar (activated partial thromboplastin time 45-60 seconds to 42-88 seconds; activated clotting time 180-200 seconds to 200-220 seconds; thromboelastography in 1 study). CONCLUSION Bivalirudin loading dose was not always used; infusion range and anticoagulation targets were different. In this systematic review, we discuss the reasons for this variability. Larger studies are needed to establish the optimal approach with the use of bivalirudin for ECMO.

The Family’s Financial Support as a “Poisoned Gift”: A Family Embeddedness Perspective on Entrepreneurial Intentions

We argue that greater availability of financial support by the family for creating a new venture entails stronger financial and non-financial obligations. Cognizant of these obligations, potential founders anticipate negative performance implications for the planned firm and threats to the family system in the case of their non-fulfillment. We thus postulate that the formation of actual entrepreneurial intentions is less likely the greater the available financial support. We confirm this by studying a sample of 23,304 respondents from 19 countries and find the negative relationship to be dependent on family cohesion and on individual entrepreneurial self-efficacy.

What makes next generation members found their own firm: knowledge, contacts, or money?

To increase our understanding of the formation of students' intentions to found an own firm, research needs to systematically integrate theory of planned behavior, resource-based view, and family business literature. To date, however, an explicit and systematic integration of these perspectives cannot be found. We attempt to close this gap by explicitly investigating founding intentions of students with family business background. More specifically, we examine how the provision of human, social, and financial resources by the family affects students' desirability and feasibility perceptions, and ultimately founding intentions. Our analysis based on a sample of 14'290 students from 26 countries reveals that both desirability and feasibility perceptions mediate the relationships between all three types of resources and founding intentions. Interestingly, the provision of financial resources is negatively related to both desirability and feasibility perceptions. These findings illustrate the research potential of a combination of theory of planned behavior with the resource-based view, especially in the family business context. Our study thus offers valuable contributions to literature on career choices, theory of planned behavior, and family business, as well as to practice.
