Multi-resolution morpho-bathymetric survey results at the Pozzuoli–Baia underwater archaeological site (Naples,Italy)

Here we show the results of two morpho-bathymetric surveys carried out on the underwater archaeological area of the Pozzuoli Bay (Naples, Italy). Such area is enclosed in the Campi Flegrei active volcanic complex, where bradyseism and recent volcanic activity strongly influenced the coastline shape over the last 2 Ka. The Digital Elevation Model (DTM) of the seafloor allowed to draw the main archaeological features of the Bay, that also include the military complex of Portus Iulius and the ancient thermal and villa complex of Baianus Lacus. The extraction of archaeological features from DTM was achieved thanks to the use of a GIS-derived tool based on the profile curvature algorithm. Thus, the Villa dei Pisoni (1st Century B.C.) and the thermal complex of Secca delle Fumose were investigated by using ultra-high resolution DTMs, that show the presence of Roman pilae for the protection of coastal buildings and also the inner planimetry of the Villa dei Pisoni complex. The observation of coastal engineering structures give also the opportunity to formulate some hypothesis on the evolution of morphology and of the sedimentary pattern of the area, while depth of archaeological remains allowed a rough computation of the rate of subsidence, resulted to be 2.55 (±0.5) mm/y for the Eastern sector (Pozzuoli) and 2.90 (±0.5) mm/y for the western (Baia).     

Socialism,Antifascism and Anti-Totalitarianism: The Intellectual Dialogue (and Discord) between Andrea Caffi and Nicola Chiaromonte (1932–1955)

Summary

This article reconstructs the personal and intellectual friendship between two cosmopolitan intellectuals: Andrea Caffi (1887–1955) and Nicola Chiaromonte (1905–1972), who met while in exile in Paris in 1932. After a brief recapitulation of their previous biographies, and an overall presentation of their participation in the revolutionary antifascist group ‘Giustizia e Libertà’ (GL) in the thirties, this article provides a detailed analysis of their dialogues and disagreements in the forties and fifties on the topics of socialism and revolution, antifascism and anti-totalitarianism, utopia and history. Particular attention is devoted to their contribution to the debates in the antifascist journal of GL (published in Paris, 1932–1935) and in the radical journal of Politics (published in New York, 1944–1950). Examined closely, the friendship between Caffi and Chiaromonte appears as a sequence of convergences and divergences, understandings and ruptures, which reflect the tensions and lacerations of the European civil war and its post-war legacy (intertwined with and overlapping the cultural Cold War). Looked at again from a distance, however, it reveals a fundamental intellectual unity—a profound apolitical affinity in a century of radical politics which had fed wars, revolutions and totalitarian regimes.     

Legitimism,liberalism and nationalism: the nature of the relationship between North and South in Italian unification

During the years following national unification, the Mezzogiorno became one of the greatest problems for the Italian government. On the one hand, because of its social and economic backwardness and the loyalty of some sections of the population to the previous illiberal government, it was devalued by the national political and military elite as a part of the large and undeveloped ‘South’ of the world, which was at that time affected by the criticism of ‘orientalistic’ Western discourse. On the other hand, it was also the place where the democratic and progressive opposition to the moderate liberal national rulers was stronger. A transnational and transregional perspective shows how the Mezzogiorno contained two different coexisting nations, a reactionary and a progressive one, which were in mutual conflict and, at the same time, on different grounds, in conflict with the central State. Building the state in the South meant, for the Italian liberal elites, discovering an ambiguous and dangerous periphery of the Nation.     

Aggregation of Regional Economic Time Series with Different Spatial Correlation Structures. 具有不同空间相关结构的区域经济时间序列集成

In this article, we compare the relative efficiency of different forecasting methods of space‐time series when variables are spatially and temporally correlated. We consider two cases: (1) univariate forecasting (i.e., a space‐time series aggregated into a single time series) and (2) the more general instance of multivariate forecasting (i.e., a space‐time series aggregated into a coarser spatial partition). We extend the results in the literature by including the consideration of larger datasets and the treatment of edge effects and of negative spatial correlation. We first introduce a statistical framework based on the space‐time autoregressive class of random field models, which constitutes the basis of our simulation study, and we present the various alternative forecasting methods considered in the simulation. We then present the results of a Monte Carlo study related to univariate forecasting. In order to allow a comparison with the findings of Giacomini and Granger (2004), we consider the same forecasting strategies and the same combinations of the parameter values used there, but with a larger parametric set. Finally, we extend our analysis to the case of multivariate forecasting. The outcomes obtained provide operational suggestions about how to choose between alternative forecasting methods in empirical circumstances.     

Application of a new typological approach to classifying denticulate and notched tools: the study of two Mousterian lithic assemblages

Identifying tools by means of morphological attributes are widely used in lithic studies to categorize retouched artifacts from different archaeological periods. This procedure has facilitated the exchange of information between separate researchers and has improved the comparison of different assemblages. In these classifications, denticulates and notched tools have been regularly interpreted as analogues and chronologically unvaried in different and vast territories. Based on the definitions developed by Bordes, the denticulate category has become a catchall for any kind of tool bearing concavities. In this paper a new quantitative approach to the classification of denticulates and notched tools is proposed. The new methodology is based on measuring the length of notches and their distribution on the perimeter of the blank. Analyzing the lithic series of the Abric Romaní rock-shelter (Spain) and Grotta Maggiore di San Bernardino (Italy) led to the identification of 11 redundant forms: eight denticulates and three notched tools. Moreover, the application of Kuhn’s Geometric Index of Unifacial Reduction brought local manufacturing trends to light, calling into question the presumed geographical uniformity of these categories of artifacts.     

Embalming methods and plants in Renaissance Italy: two artificial mummies from Siena (central Italy)

Knowledge of the embalming methods used in Renaissance Italy comes not only from the literary texts of physicians and surgeons of that period, but also from artificial mummies which have been found. In 1999 two mummified bodies, dated back to the end of 15^th and beginning of the 16^th century, were recovered in a crypt of the hospital chapel of Santa Maria della Scala in Siena (central Italy). The individuals were identified as Salimbene Capacci (1433–1497), Rector of the hospital, and his wife, Margherita Sozzini (?-1511). The mummies were submitted to autopsy and paleopathological examination, which included Computed Tomography. Palaeobotanical and palynological analyses were performed on the vegetable materials and plants used to fill the body cavities. This study was carried out with a multidisciplinary perspective, that allowed us to reconstruct the embalming techniques and substances used for mummification. The results are compared with the evidences provided by other mummies and embalming handbooks of that time.
