Chemical analyses of the earliest pigment residues from the uttermost part of the planet (Beagle Channel region,Tierra del Fuego,Southern South America)

This paper presents the results of chemical analyses of the organic and inorganic fractions of pigment residues found in three archaeological sites located in the Beagle Channel region, Tierra del Fuego, Southern South America. Twenty-one archaeological samples have been analysed through XRD, SEM–EDX, FT-IR and GC–MS in order to characterise their inorganic colouring components and to search for the presence of organic substances used as binders. Lipids found in some samples are considered as potential binders. These organic components are compared to those found in archaeological sediment samples from the same layers where the pigments have been found, in order to search for potential taphonomic contaminations of the latter by the former. Results show that such contaminations are unlikely, hence the lipid contents are deemed of anthropic origin. The pigment sample results are also compared to data from analyses of natural sediment samples collected in several localities of the Beagle Channel in order to search for potential natural pigment sources. Results show that organic and inorganic components of these sediments are not the same than those present in the archaeological pigment samples, hence the pigment raw material sources have not been yet located. All these data provide for the first time evidence of the existence of ancient activities of pigment sourcing and paint preparation with organic binders which range from 6000 BP to 1900 BP in the southernmost region of the planet.     

History as it really wasn't: the myths of Italian historiography

According to a number of influential Italian contemporary historians, Italian political history since Unification has been distorted by politicized scholarship and the existence of a large number of untenable political myths. These views are presented in the volume Miti e storia dell'Italia unita (1999). In this roundtable, Ruth Ben-Ghiat, Carl Ipsen and David Kertzer discuss this thesis with two of its leading proponents: Ernesto Galli della Loggia and Luciano Cafagna. Secondo alcuni studiosi dell'Italia contemporanea, la storiografia dell'Italia unita è stata travisata dalla tendenza a scrivere testi politicizzati e dall'esistenza di numerosi miti politici infondati. In questa tavola rotonda, Ruth Ben-Ghiat, Carl Ipsen e David Kertzer discutono le tesi proposte nel volumi Miti e Storia dell'Italia Unite 1999 (Bologna, Il Mulino) con due suoi sostenitori: Ernesto Galli della Loggia e Luciano Cafagna.     

Fossil marsupial predators of South America (Marsupialia,Borhyaenoidea): bite mechanics and palaeobiological implications

Borhyaenoids were marsupial predators that inhabited South America during the Cenozoic. They were very significant because no other mammals rivaled them as terrestrial hunters of large prey. Here we estimate the bite force of three species of borhyaenoids by two different methods to infer predatory behaviour in extinct taxa. One of the methods uses mainly the skull and only some simple measurements of the mandible; the other uses several measurements within the dentary. The results show that bite forces are very high in comparison to predators of the order Carnivora, a feature manifest by several other living and extinct marsupial predators. Differences in size, bite mechanics and special adaptations among the borhyaenoids suggest a very wide range of predatory behaviours that rival those represented in the extant families of the Order Carnivora.     

Higher Education Excellence and Local Economic Development: The Case of the Entrepreneurial University of Twente

By tradition or intellectual necessity, universities pursue a main objective: increasing and transferring knowledge that is internationally relevant for the whole of mankind. But new powerful socio-economic forces are demanding universities to be engaged in regional economic development and their knowledge to be relevant in terms of local employment, university spin-offs and growth. These two objectives are traditionally considered as not complementary or even mutually exclusive. Through a case study regarding the Dutch University of Twente, this article shows that local economic relevance and international excellence are not incompatible objectives: they were not at the University of Twente; they can be reached even in a new born and poor endowed university, located in a peripheral, depressed and not industrialized countryside. This article argues that a strong entrepreneurial vision and the adoption of a different concept of knowledge may be the key for other small and peripheral European universities, in order to reach both local economic relevance and international excellence. The article will contribute and enrich the regional studies debate, introducing to it some higher education policy issues and ideas.     

The demographic impact of irrigation projects: a comparison of two case studies of the Ebro basin,Spain, 1900–2001

Water management and population issues have always been particularly important in Spain, a country historically characterized by severe environmental constraints on agricultural growth and intense rural depopulation. This paper evaluates whether irrigation projects in Spain over the course of the twentieth century have achieved one of their main objectives, which was to reduce rural population decline. This paper makes two contributions. First, we compare the evolution of population in two of the earliest and most ambitious irrigation projects in Spain, the Riegos del Alto Aragón (Upper Aragon Irrigation System) and the Canal de Aragón y Cataluña (Aragon and Catalonia Canal System), both located in the Ebro basin. Second, the time period of the study spans an entire century. This long-term approach is crucial if we accept that irrigation requires time to consolidate its effects and, therefore, its impact on population may be long delayed. We show that the evolution of population in each of the two projects has been substantially different. We also analyze the factors that have caused or prevented population growth. We argue that financial, economic and environmental limitations have been significant, but also that political and geographical factors have played a major role.
