Aretusa: continuity,rupture and space for intervention (1944–46)

This article focuses on the cultural activity of Aretusa (1944–46), a journal that was deeply connected to the inner circle of philosopher and politician Benedetto Croce (1866–1952). The article analyses the role played by periodical editors Francesco Flora (1891–1962) and Carlo Muscetta (1912–2004) in shaping the mission and direction of this journal. By drawing on Pierre Bourdieu’s theory of habitus, and the notion of hysteresis in particular, this study details the factors influencing the aesthetic dispositions, political positioning and the wider impact of historical circumstances on the cultural practice of each editor while at the helm of the review.     

The Imperial Visual Archive: Images,Evidence, and Knowledge in the Early Modern Hispanic World

This article examines the role of images as evidence and sources of knowledge in the early modern Hispanic world, arguing for the continued importance of visual epistemology as a technique for producing and circulating knowledge from the sixteenth through the eighteenth centuries. Visual materials played a central role in the production of knowledge, scientific and imperial, and served as key instruments for addressing the considerable challenges of distance and place posed by the geographical expanse of the empire. Historiographically, the article highlights the active generation of scientific knowledge in the Hispanic world and connects it to imperial and administrative practices; it highlights trans-regional channels of circulation, demonstrating the connected histories of the viceroyalties and peninsula and the multidirectional trajectories in which information and knowledge moved; and it points out deep connections between earlier and later colonial periods. Methodologically, the essay explores the potential of images as historical sources, suggesting that the high status of images in the early modern Hispanic world led to the creation of an enormous pictorial archive that deserves the same level of scholarly attention and rigor that has been lavished on the textual archive.     

Hazelnut economy of early Holocene hunter–gatherers: a case study from Mesolithic Duvensee,northern Germany

Throughout the greater part of human evolution in Europe, use of plant foods is invisible and thus might have played a secondary role in nutrition. Ecological changes at the beginning of the early Holocene provoked innovations in early Mesolithic subsistence, focusing on the rich plant resources of the increasingly forested environment. High-resolution analyses of the excellently preserved and well-dated special task camps documented in detail at Duvensee, Northern Germany, offer an outstanding opportunity for case studies on Mesolithic subsistence and land use strategies. Quantification of the nut utilisation demonstrates the great importance of hazelnuts. These studies revealed very high return rates and allow for absolute assessments of the development of early Holocene economy. Stockpiling of the energy rich resource and an increased logistical capacity are innovations characterising an intensified early Mesolithic land use, which is reflected in the stable tradition of uniform seasonal settlement patterns at early Mesolithic Duvensee. The case study reveals characteristics in early Mesolithic subsistence and land use that anticipate attributes of the Neolithic economy.     

Review of Archaeological Research in Angola

This article examines the historical processes that shaped the development of archaeological practice in Angola during the Portuguese colonial period and the aftermath of political independence. Using published works, unpublished reports, and photographic records, we examine the research themes, actors, scholars, and institutions that influenced archaeological research in the country. We also used documents and museum collections in Angola and Portugal to create a GIS database of Angola’s archaeological findings. This study highlights the events, personalities, and priorities that motivated earlier investigations, and the geographical distribution of prehistoric sites. We hope this study will be a resource for guiding future archaeological research in Angola.

     

G.E. Moore and political philosophy: Gerald F. Shove's fellowship dissertation (1911)

In 1911 Gerald F. Shove, later to become a leading Cambridge economist, submitted to King's College a fellowship dissertation on the application of G.E. Moore's ethical philosophy to political theory. In the article the dissertation, hitherto unpublished, is discussed with reference to both the acceptance and elaboration of Moore's Principia Ethica by the members of the Apostles and Bloomsbury groups and Shove's intellectual and personal biography. The thesis tackles some major concepts in political theory like the nature of human societies, self-government, justice and freedom.     

SEM and electrochemical characterization of bronze artifacts from the Francavilla archaeological site

The excavations in the necropolis of the Francavilla Marittima archaeological area, in Calabria, have brought to light the rich burial artifacts and materials, dated between the end of the ninth and sixth centuries BCE. SEM/EDS analysis was conducted on some sections taken from a bronze artifact classifiable as an armilla or fibula fragment. Our aim was to elucidate the nature of the corrosion processes acting on the specimen. SEM investigation detected the segregation of tin towards the outer layer and a depletion of the copper content in the same region. Furthermore, the elemental distribution maps of the sections analyzed evidenced the presence of chloride ions in the border area between the corrosion patina and the metal alloy. Such anion migration of chloride ions into the interior of the alloy leads to a particular variant of the type of corrosion of structure that in the literature has been identified as structure I.A cavity electrode designed for electrochemical measurements of powders was used to perform cyclic voltammetry experiments devoted to explore the activity of the patina covering the surface of the bronze fragment. The surface layer consists mainly of tin and tin oxides; the layer immediately beneath it contains copper oxides. An increase of reactivity was shown in an acidic environment. The activity of the patina is greatly reduced at pH 5 and appears to be zero at neutral pH.     

From a White Desert to the Largest World Deposit of Lithium: Symbolic Meanings and Materialities of the Uyuni Salt Flat in Bolivia

The Uyuni salt flat (Salar de Uyuni) in Bolivia possesses the largest lithium deposit in the world. Over the past 40 years, this location has been commodified and radically transformed. This paper examines how a landscape, understood from its material attributes and qualities, shapes and is shaped by social relations unfolding in a process of commodification and mining expansion. Based on primary qualitative data, the paper explores two elements: (1) how the symbolic meaning of this landscape has changed over time for the surrounding indigenous communities; and (2) how the different materialities of the salt flat as landscape, as ulexite and as lithium allow understanding of the drivers of socio‐environmental change and conflict in this region. The paper argues that social relations and governance frameworks are interlinked with changing symbolic meanings and the different materialities of the Uyuni salt flat.     

Modeling the Impact of Technological Innovation on Environmental Efficiency: A Spatial Panel Data Approach

Technological progress has widely been acknowledged as a key driver in the achievement of environmental sustainability, and a new concern has recently arisen for assessing the role of differences in regional innovation performances with respect to the pursuit of pollution targets. We investigate the impact of innovative activities on environmental efficiency at the regional level, adopting a spatial panel data approach to account for dependence between geographical observations and to get deeper insights into spatial knowledge spillovers arising from agglomeration economies. The spatial panel analysis covers 103 Italian provinces (equivalent to NUTS3 regions) on four major air pollutants (i.e., CO₂, CH₄, NMVOC, CO) over the 1995–2010 period. Our findings show that the state of local technology development, proxied by patents, has a positive impact on GDP emission efficiency and that its magnitude is higher for more localized pollutants as a result of larger spillover effects. Finally, to analyze the Italian North-South dualism of emission levels of pollutants, we offer a spillover effect study to emphasize the remarkable difference among effects in the territory. This calls for closer attention to the local relevance of the pollution damage when environmental impact of innovation strategies is to be evaluated.     

Thermographic Survey at Hagia Sophia: Main Arches,Pendentives and Tympana

Hagia Sophia is one of the oldest and most complex existing monuments. Many unanswered questions are still open on the historical and constructive evolution of this monument. The boundaries between the different construction phases and the details of the masonry and materials used in the various phases are still not defined with precision.

The thermographic survey, carried out inside the monument, made ??it possible to answer some of these questions by specifying the exact location of the past interventions and the variability of the materials employed allowing a better understanding of the constructive history of the monument. The technique was applied at a great distance and in normal environmental conditions, taking advantage of the high thermal sensitivity of the instrumentation. The results achieved confirm the validity of the technique in the study of ancient buildings.
