Business Clusters in Eastern Europe: Policy Analysis and Cluster Performance

Clusters have increasingly become an essential part of policy discourses at all levels, EU, national, regional, dealing with regional development, competitiveness, innovation, entrepreneurship, SMEs. These impressive efforts in promoting the concept of clusters on the policy-making arena have been accompanied by much less academic and scientific research work investigating the actual economic performance of firms in clusters, the design and execution of cluster policies and going beyond singular case studies to a more methodologically integrated and comparative approach to the study of clusters and their real-world impact. The theoretical background is far from being consolidated and there is a variety of methodologies and approaches for studying and interpreting this phenomenon while at the same time little comparability among studies on actual cluster performances. The conceptual framework of clustering suggests that they affect performance but theory makes little prediction as to the ultimate distribution of the value being created by clusters. This thesis takes the case of Eastern European countries for two reasons. One is that clusters, as coopetitive environments, are a new phenomenon as the previous centrally-based system did not allow for such types of firm organizations. The other is that, as new EU member states, they have been subject to the increased popularization of the cluster policy approach by the European Commission, especially in the framework of the National Reform Programmes related to the Lisbon objectives. The originality of the work lays in the fact that starting from an overview of theoretical contributions on clustering, it offers a comparative empirical study of clusters in transition countries. There have been very few examples in the literature that attempt to examine cluster performance in a comparative cross-country perspective. It adds to this an analysis of cluster policies and their implementation or lack of such as a way to analyse the way the cluster concept has been introduced to transition economies. Our findings show that the implementation of cluster policies does vary across countries with some countries which have embraced it more than others. The specific modes of implementation, however, are very similar, based mostly on soft measures such as funding for cluster initiatives, usually directed towards the creation of cluster management structures or cluster facilitators. They are essentially founded on a common assumption that the added values of clusters is in the creation of linkages among firms, human capital, skills and knowledge at the local level, most often perceived as the regional level. Often times geographical proximity is not a necessary element in the application process and cluster application are very similar to network membership. Cluster mapping is rarely a factor in the selection of cluster initiatives for funding and the relative question about critical mass and expected outcomes is not considered. In fact, monitoring and evaluation are not elements of the cluster policy cycle which have received a lot of attention. Bulgaria and the Czech Republic are the countries which have implemented cluster policies most decisively, Hungary and Poland have made significant efforts, while Slovakia and Romania have only sporadically and not systematically used cluster initiatives. When examining whether, in fact, firms located within regional clusters perform better and are more efficient than similar firms outside clusters, we do find positive results across countries and across sectors. The only country with negative impact from being located in a cluster is the Czech Republic.

L'evoluzione poetica delle Grazie di Ugo Foscolo. Un'ipotesi di commento.

Il presente progetto di ricerca propone l’esegesi di alcune sezioni delle Grazie di Ugo Foscolo, secondo l’Edizione Nazionale (1985), a cura di Pagliai-Scotti. È stato fornito il commento delle seguenti sezioni: Prima redazione dell’Inno, Seconda redazione dell’Inno e Appendice alla Seconda redazione dell’Inno, Versi del Rito, Quadernone, Stesure milanesi: Viaggio delle api e frammenti sparsi. Tutte le stesure della Prima redazione dell’Inno e alcuni frammenti delle Stesure milanesi non erano mai stati commentati fino ad ora. Il commento offre una ricostruzione dell’intertesto delle Grazie – le fonti letterarie, erudite e figurative –, e punta alla storicizzazione e alla contestualizzazione della poesia di Foscolo. Attraverso lo studio dei frammenti nella loro evoluzione è possibile intendere come i tre inni, diventati uno soltanto nella redazione del Quadernone, rappresentino la sintesi di tutto il sapere e gli interessi foscoliani (eruditi, scientifici, filosofico-estetici e letterari), e come essi, sin dai primi esiti poetici, siano specchio delle esperienze biografiche dell’autore. Il commento proposto nella tesi ribadisce la complessità della poesia delle Grazie, nelle sue componenti civili e didattiche. Esso avanza nuovi e importanti spunti di indagine, ponendosi come viatico indispensabile per un futuro commento integrale.

Molecular variability of Meningococcal antigens in carriage and disease strains and in other Neisseria species

This PhD thesis is focused on the study of the molecular variability of some specific proteins, part of the outer membrane of the pathogen Neisseria meningitidis, and described as protective antigens and important virulence factors. These antigens have been employed as components of the vaccine developed by Novartis Vaccines against N. meningitidis of serogroup B, and their variability in the meningococcal population is a key aspect when the effect of the vaccine is evaluated. The PhD project has led to complete three major studies described in three different manuscritps, of which two have been published and the third is in preparation. The thesis is structured in three main chapters, each of them dedicated to the three studies. The first, described in Chapter 1, is specifically dedicated to the analysis of the molecular conservation of meningococcal antigens in the genomes of all species classified in the genus Neisseria (Conservation of Meningococcal Antigens in the Genus Neisseria. A. Muzzi et al.. 2013. mBio 4 (3)). The second study, described in Chapter 2, focuses on the analysis of the presence and conservation of the antigens in a panel of bacterial isolates obtained from cases of the disease and from healthy individuals, and collected in the same year and in the same geographical area (Conservation of fHbp, NadA, and NHBA in carrier and pathogenic isolates of Neisseria meningitidis collected in the Czech Republic in 1993. A. Muzzi et al.. Manuscript in preparation). Finally, Chapter 3 describes the molecular features of the antigens in a panel of bacterial isolates collected over a period of 50 years, and representatives of the epidemiological history of meningococcal disease in the Netherlands (An Analysis of the Sequence Variability of Meningococcal fHbp, NadA and NHBA over a 50-Year Period in the Netherlands. S. Bambini et al.. 2013. PloS one e65043).

L'inno avestico agli Aməsha Spəṇtas (Yasht 2). Testo critico e traduzione con commentario storico religioso

L'inno dedicato ai sette Amesha Spəṇta è parte della produzione avestica recenziore, e si compone in gran parte di porzioni testuali riprese da altri testi avestici a loro volta di formazione tardiva. Lo Yašt si divide in tre parti principali: le stanze 0-10; 11-14; e infine la stanza 15 che comprende la formula di chiusura tipica degli inni avestici. La prima sezione (2.0-10) è composta dalla formula di apertura, incompleta rispetto a quelle dei restanti inni, seguita dai primi sette capitoli di entrambi i Sīh-rōzag compresi i Gāh. Le stanze centrali (11-14) si caratterizzano per l'assenza di passi gemelli, un elevato numero di hapax e di arcaismi formali e inoltre, una grande variabilità nella tradizione manoscritta. Si tratta di una formula magica per esorcizzare/allontanare demoni e stregoni, che doveva essere recitata per sette volte. Tale formula probabilmente rappresentava in origine un testo autonomo che veniva recitato assieme ad altri testi avestici. La versione a noi pervenuta comprende la recitazione di parte di entrambi i Sīh-rōzag, ma è molto probabile che tale arrangement sia soltanto una sequenza recitativa che doveva coesistere assieme ad altre. Attualmente la formula magica viene recitata principalmente assieme allo Yasna Haptaŋhāiti, senza le restanti stanze dell'inno nella sua versione geldneriana. Il testo sembra nascere come formula magica la quale venne recitata assieme a diversi testi avestici come per esempio parti dello Sīh-rōzag. In un periodo impossibile da stabilire con certezza la versione viene fissata nella forma a noi pervenuta nella maggior parte dei manoscritti e per la sua affinità formale probabilmente interpretato come inno e perciò incluso nell'innario avestico.
