What Makes SMEs more Likely to Collaborate? Analysing the Role of Regional Innovation Policy

The last 20 years have witnessed the diffusion of regional innovation policies supporting networks of innovators. The underlying aim of these policies is to encourage firms, particularly small and medium-sized enterprises (SMEs), to undertake collaborations with organizations possessing complementary knowledge. Focusing on a set of SMEs that have participated, over time, in several innovation networks funded by the same regional government, the paper investigates how their relationships have evolved with respect to the following aspects: (i) reiteration of pre-existing relationships as opposed to experimentation with new relationships; (ii) collaboration with organizations possessing complementary rather than similar knowledge and competencies; (iii) creation of local relationships rather than experimentation with extra-local collaborations; (iv) reliance upon intermediaries to connect with other organizations. Our findings reveal that the involvement in these policy-supported networks changed the firms' relational patterns, leading them to collaborate with a wider variety of agents than those with whom they were linked before the policies. Sectoral heterogeneity had a negative effect on the probability of collaborating, while co-localization increased the likelihood of collaborating. Mutual involvement with intermediaries also had a positive effect. However, in the case of firm-to-university relationships only specialized intermediaries were likely to perform a positive role and, therefore, encourage networking.     

Migrations and militant research? Some brief considerations

Abstract

The first part of the essay raises some doubts about the possibility of understanding research on migrations as ‘militant research’. A brief analysis of the discourse where research work is confined allows to glimpse at the deferral of two moments, that of militancy and of research. In such deferral a temporal dimension is at stake: first, the researcher wanders in the world or ‘wanders through the texts’, then he/she lingers on for a while in order to produce a discourse. It is necessary to interrogate this deferred dimension, not to elude it hence running the risk of reproducing the classical philosophical gesture of placing the speaking (and thinking or researching) subject at a ‘theoretical distance’. In the second part of the essay, the deferral between militancy and research is developed with reference to the struggle of the mothers and the families of Tunisian migrants, who left towards Italy and Europe right after the Tunisian revolution and who are ‘missing’ in the Mediterranean. The stubbornness of Tunisian mothers' struggle, which interrupts the path of virtualization of their sons, is countered to the oscillating ontology that migration policies enact, oscillating between the being and the not-being there of persons, dealing with the physicality of people, produced as migrants and rendering the bodies not completely adhering to space and as fantoms. The essay closes with a few considerations on the topic of a politics of testimony and its risks.     

Transport Amphorae in the West Hallstatt Zone: Reassessing Socio‐Economic Dynamics and Long‐Distance Mediterranean Exchange in Western Central Europe in the Early Iron Age

Trade and cultural relations between western Central Europe and the Mediterranean world in the Early Iron Age remain a major topic of discussion. The products exchanged were mainly connected with the ritual preparation and social consumption of Mediterranean wine. This article examines the question through a comparative study of transport amphorae from the entire West Hallstatt zone. The systematic analysis is based on a specialized study carried out on the material itself. Typological analyses allow us to identify where amphorae originated; previously this was thought to have been just Massalia but this now needs to be expanded to the whole Mediterranean Basin. An analysis of the distribution of amphorae enables us to identify the trajectory these products followed. A comparison with amphora types attested in potential ports in southern France and northern Italy suggests possible trade routes for specific types. Finally, a new chronological scheme for amphorae provides insights into the economic reasons behind these imports and the social impact these products had, enabling us to identify broader socio‐economic trends and long‐distance exchange patterns in western Central Europe.     

Dome Strengthening By Encircling Ties: A Monitored Experiment

This study describes a new strategy of conservation of historical monuments based on the combined use of monitoring analysis and empiric reappraisal. Over time, the mechanical behavior of domes—their lack of stability due to the horizontal thrusts generated by their self-weight—has been analyzed by architects and engineers, starting from the observation of damage. This process, which was mathematically demonstrated for the first time by the famous Viviani’s analysis of Santa Maria del Fiore in Florence, has provided over the centuries a number of enhancements in dome structural conception, thus leading to the final solution, referred to as encircling tie rod intervention. Based on these premises, the experimental case of Santa Maria del Quartiere dome in Parma, Italy, is discussed herein. Indeed, it has been considered a good opportunity to present the method used in its strengthening-intervention assessment, further validated by the monitoring system installed. In this monitored in-scale experiment, the empiric classical solution to the primeval dome’s thrust finds its confirmation and offers further possibilities of recalibration during time, thus indicating structural monitoring that may be described as a possible and desirable “alternative to intervention”, in step with “minimum intervention” and “reversibility” principles.     

Egyptian Blue cakes from the Ayanis fortress (Eastern Anatolia,Turkey): micro-chemical and -structural investigations for the identification of manufacturing process and provenance

The microstructure and chemical composition of blue cakes, found during the archaeological excavation of the Ayanis fortress (Eastern Anatolia, Turkey), have been investigated by means of scanning electron microscopy combined with energy dispersive spectrometry (SEM–EDS), X-ray diffraction (XRD), micro-Raman (μ-Raman) and optical microscopy (OM) techniques. The analysis of the Ayanis cakes has shown the presence of Egyptian blue (i.e. CuCaOSi₄O₁₀, cuprorivaite), as the major component, intermixed with minor amount of other phases such as partially reacted quartz grains, an adherent glass phase and copper oxides. Since the finding of Egyptian Blue in Turkey has been never reported so far, great attention has been paid to its characterisation. The micro-chemical and micro-structural investigations of the Ayanis cakes have allowed a further insight into the manufacturing process and into the sources of the starting materials. The results of the characterisation have revealed some significant differences with respect to Egyptian blue cakes found in Egypt and Mesopotamia, as for instance the absence of tin excluded the use of bronze scraps or filings in their preparation differently from those produced in Egypt and Mesopotamia. Furthermore, some peculiarities of Egyptian blue found in Ayanis, as the detection of zinc in the cakes, allow to put forward the hypothesis of a local production considering that a large part of the bronze artefacts found at the Ayanis fortress is characterised by the presence of zinc as minor alloying element.     

Democracy and the rights of women in the thinking of Giuseppe Mazzini

Addressing Italian workers in his Doveri dell’uomo of 1860, Mazzini unequivocally laid out his thoughts on women's rights. The thinker from Genoa, all the more after his encounters with other political philosophers from different national environments such as Britain and France, saw the principle of equality between men and women as fundamental to his project of constructing first the nation, and second a democratic republic. In his ideas regarding emancipation Mazzini, who spent a good 40 years of his life in exile, was one of a small group of European thinkers who in challenging the established customs and prevailing laws not only hoped for the end of women's social and judicial subordination, but also held that changes to the position of women were essential to the realisation of their political projects. Thanks to this respected group of intellectuals, the issue of female emancipation found a place in the nineteenth-century European debate regarding democracy and the formation of national states. The closeness of the positions of these thinkers, and their commitment in practice as well as theory, mean that it can legitimately be argued that in the course of the nineteenth century a current of feminist thinking took shape. This was born of the encounters between and reflections of various intellectuals who met first in France and then in England, and who came to see women's rights not just as a discrete issue for resolution but as fundamental to their projects for the regeneration of nations, or, as in the Italian case, for the construction and rebirth of a nation.     

Multi-technique characterization of dyes in ancient Kaitag textiles from Caucasus

Kaitag textiles, named after the Kaitag district of Southwest Daghestan, Russia, where it is being manufactured, are a unique embroidered textile art form. They were used by families on special occasions such as the birth, marriage or death of one of their members and were thus passed down from generation to generation as family heirlooms. Today, only a few hundred of these precious antique specimens can still be found, and surviving examples are mostly from the seventeenth and eighteenth centuries. In this article, an extensive work for the scientific analysis of Kaitag textiles is presented as the logical continuance and updating of the investigations performed by thin layer chromatography almost two decades ago. A multi-technique approach involving the combined use of micro-invasive and nondestructive techniques suitable for in situ analyses was used, aiming to identify the colourants of Kaitag textiles and the inks employed for the underlying drawing. Analyses were performed by high-performance liquid chromatography, surface-enhanced Raman spectroscopy, scanning electron microscopy combined with energy dispersive X-ray analysis, as well as visible reflectance spectroscopy and X-ray fluorescence. In addition, infrared reflectography and ultraviolet fluorescence were employed to visualise underlying drawings and possible restorations. Corrosion phenomena observed in brown- and black-dyed areas were also investigated.
