Determinants of Market Extension in Knowledge-Intensive Business Services: Evidence from a Regional Innovation System

Several studies have emphasized the role of knowledge-intensive business services (KIBS) in fostering innovation in metropolitan areas and regional innovation systems. Such areas are capable of expressing a strong demand for KIBS and consequently stimulate the rise and growth of KIBS. Despite an abundance of literature on KIBS emphasizing the relevance of spatial proximity to customers, many KIBS develop relationships on a broader national or even international scale. No studies have focused explicitly on this apparent discrepancy as yet. The aim of this paper is therefore to fill this theoretical and empirical gap by explaining the firm-level factors relating to the market extension of KIBS within the framework of regional innovation systems. Our analysis is based on a quantitative study on more than 150 KIBS supplying design or communication services located in the Veneto region (north-eastern Italy), an area that can be described as a regional innovation system. Five variables were considered, that is, size, experience, service standardization, investments in network technologies and relational intensity. Our results confirm that three of these variables, but not service standardization and relational intensity, correlate positively with the market extension of KIBS. Policy implications are also discussed.     

Disclosing mineralogical phases in medioeval iron nails by non-destructive neutron techniques

There is not only one methodology for the study of mineralogical phases in archaeological samples. In this paper, we discuss a strategy applied to ancient iron nail samples completely based on non-destructive analyses. The archaeological samples come from the archaeological site of Valle delle Forme (province of Brescia–Italy) and date back to the 1300–1400 ad. Neutron-based techniques, like time-of-flight neutron diffraction and neutron tomography, have been used to determine the mineralogical composition and the structure of nails. An independent check for the assessment of the presence of different mineralogical phases was given by Raman spectroscopy. The combination of different non-destructive techniques has provided very useful information on their chemical composition, nature of the patina and corrosion features of the nails (also in the bulk of the samples).     

Age estimation by tooth/pulp ratio in canines by peri-apical X-rays: reliability in age determination of Spanish and Italian medieval skeletal remains

Estimation of age at death is an unavoidable step in the process of human identification, both in forensic practice and in the anthropological and palaeopathological study of skeletal remains. In several cases, in which medical or demographic records are completely lacking, a reliable estimation of the age at death becomes very important. Skeletal remains from archaeological contexts suffer from several biasing factors such as post-mortem changes, taphonomy and various burial practices depending on age, sex and social status of the deceased persons.     

Rewriting the end of the Early Bronze Age in the United Arab Emirates through the anthropological and artefactual evaluation of two collective Umm an-Nar graves at Hili (eastern region of Abu Dhabi)

The Hili archaeological complex in Al Ain (U.A.E.) is important for its wealth of third-millennium BC Umm an-Nar burial and settlement sites. Two of the most significant burial sites are Tomb N at Hili and Tomb A Hili North. The latter is a classic circular Umm an-Nar monumental grave, while Hili N is a pit-grave, one of only two Umm an-Nar period pit-graves discovered so far in the U.A.E. Both of these tombs contained the remains of hundreds of individuals, in the case of Tomb A Hili North, more than 300, while around 600 people had been deposited in Hili N. Both population groups have been the subject of anthropological and artefactual analyses and a comparison of the findings help to shed light on the chronology of the end of the Umm an-Nar period.     

Regional Efficiency in the European Union

This paper examines existing disparities in technical efficiency levels across the European regions over the period 1986–2002. The results reveal that technical efficiency is not randomly distributed across space in the European setting. On the contrary, the different tests performed highlight the presence of positive spatial autocorrelation and spatial heterogeneity in the distribution under consideration. In fact, we have detected several regional clusters characterized by similar efficiency levels distinguishing them from the rest of the sample. Nevertheless, the estimates carried out show the existence of a process of regional convergence in terms of technical efficiency during the study period. Our findings also reveal that factors such as the regional stock of capital per worker or the patterns of productive specialization are relevant in explaining the changes in technical efficiency experienced by the European regions between 1986 and 2002.     

Late antique glass from Salapia: Tracking production and trading networks

The investigation of 38 late antique vessels from the archaeological excavation of Salapia has been performed using EMPA and LA-ICP-MS. The collection was made using impure sands and mineral soda. Among coloured glass, most vessels were made of ‘fresh’ glass. The use of colouring agents is rare, and most decoloured glass is obtained by Mn addition. Sb-decolouration is limited to one cup, and two colourless vessels show both manganese and antimony. As for provenance, the prevalence of Egyptian-HIMT glass over the Levantine is evident. Among Levantine glass, Jalame glass is represented, whereas Apollonia glass is absent. Among Egyptian (and deemed Egyptian) glass, the prevalence of HIMT glass over the other types has been observed. The high attestation of fresh glass, most notable in the earlier centuries, suggests the importation of glass in the form of finished objects, especially luxury vessels.     

The enemy underground: geostrategic intelligence and the war in Algeria

During the Algerian war (1954–1962), beside the war events proper, another conflict took place: a diplomatic and technocratic battle for the possession of Saharan oil resources in the name of national energy security. Its main actors were France, Italy, the US, and Algerian independence fighters. In the case I analyse in this paper, I show that the three Western-block countries used their local knowledge of the subsurface given by the collaboration of the three elements of: (1) geoscientists, (2) their national oil companies, and (3) their respective diplomatic bodies, in order to carve out a prominent place for themselves in the exploitation of Saharan resources. Algerian nationalists also succeeded in benefiting from this knowledge. I argue that this struggle for natural resources in a post-independence scenario, and the corresponding role of the geosciences in it, significantly contributed to influence the final configuration of the postwar Algerian hydrocarbon sector.     

The Silversmith's Workshop of Tira Del Lienzo (Totana,Murcia) In The Context of Iberian Bronze Age Metallurgy

The south‐east of the Iberian Peninsula saw deep social and political changes at the dawn of the second millennium bce . The emergence of important economic asymmetries inside communities was apparently based to a large extent on control of the secondary metallurgical production process; namely, forging. In this sense, the recently excavated architectural complex at the Argaric site of Tira del Lienzo constitutes an exceptional finding. At this site a series of macrolithic artefacts were recorded, which were related to the forging of metals and, more specifically, to the working of silver, according to morpho‐technological and functional studies (use‐wear and residue analysis).     

Radiocarbon and U-series dating of the endemic deer Praemegaceros cazioti (Depéret) from “Grotta Juntu”, Sardinia

Radiocarbon and U-series methods (²³⁰Th/U and ²³¹Pa/²³⁵U) for absolute age determination have been applied to some fossil samples from Grotta Juntu, in North Eastern Sardinia (Italy). The remains belong to the endemic deer species Praemegaceros cazioti, which is here represented by an almost complete skeleton. The three dating methods lead to concordant ages of about 7500 years BP, indicating that the skeleton was maintained as closed system after burial. Taking into consideration these results, Praemegaceros cazioti from Grotta Juntu is now the youngest representative of this species in Sardinia.
