Nicola Mai 《Modern Italy》2013,18(1):77-93
This article analyses the shifting ways in which Italy has been strategically represented in Albania during the different key passages of the latter's relatively recent history as a sovereign independent state. As a parallel narrative, the article also examines the way Albania has been equally strategically represented in Italy before and during the two periods in which Italy has been militarily involved in Albania, and the way this has been consistent with an attempt to elaborate and sustain a politically strategic definition of Italian identity and culture. The history of the asymmetrical relationship between Albania and Italy is deeply embedded in the social, cultural and political environments that are on the two shores of the Adriatic Sea. The cultural construction of Albania in Italy and vice versa of Italy in Albania should be linked to seemingly independent instances of domestic reforms. The dynamics of projective identification or dis-identification stemming from these instances should be seen as intertwined within two parallel processes of mutual definition encompassing both the colonial and the postcolonial relations between and within the two countries.  相似文献

A strange silence has long reigned in the public memory as well as in Italian historical studies regarding possible crimes committed by Italy in its colonial territories. The aim of this article is to reflect on the reasons for this silence through an examination of the major historiographical questions and a review of the few studies available on the subject. The historiographical use of the judicial category of ‘crimes’ or ‘war crimes’ should not be taken for granted, above all in examining the history of the colonial experience. The most important authors have ignored the risk that the sensationalistic use of the category ‘crime’ – in itself an extraordinary and exceptional event – can make one forget the weight of the ordinary running of a colonial power. With these precautions, the article offers a list of the principal episodes historians now unanimously define as crimes. These episodes eliminate any possibility of taking refuge in the self-absolving and vague appeals to stereotypes of Italians as ‘good people’. The article concludes by defining precisely the triple order of silences that together produced the general silence that the author considers an obstacle and a post-colonial stain on the memory of colonial Italy.  相似文献

This paper outlines the environmental history of the Tigrean Plateau (northern Ethiopia) during the Holocene, based on the available geomorphological, palynological, archaeological, and historical evidence. At present, it seems that (1) the plateau experienced a more humid climate with a denser vegetation cover during the Early Holocene; (2) Soil erosion due to clearing vegetation began in the Middle Holocene; (3) agricultural activity was intensified in the Late Holocene, as a consequence of the rise of a state; (4) demographic pressure increased from the early first millennium BC to the mid–first millennium AD, causing soil erosion; (5) environmental degradation and demographic decline occurred in the late first millennium AD; (6) the vegetation cover was regenerated in the early second millennium AD; and (7) progressive vegetation clearance started again in the second half of the second millennium AD.Cet article trace l'histoire ambiante du Plateau Tigréen dans l'Holocène en utilisant les données géomorphologiques, palynologiques, archéologiques et historiques. Il semble que (1) dans l'Holocène ancien le plateau était caractérisé par une phase humide avec une dense végétation; (2) l'érosion causée par l'abbattage de la végétation commen¸a dans l'Holocène moyen; (3) l'activité agricole s'inténsifia à la fin de l'Holocène, par conséquence de l'essor d'un état; (4) la pression démographique augmenta de plus en plus du début du premier millénaire av. J.-Ch. à la moitié du premier millénaire ap. J.-Ch.; (5) la dégradation ambiante et la diminution démographique se vérifièrent à la fin du premier millénaire ap. J.-Ch.; (6) une régéneration de la vegetation se vérifia au début du seconde millénaire ap. J.-Ch.; et (7) l'abbatage de la végétation recommen¸a dans la seconde moitié du seconde millénaire ap. J.-Ch.  相似文献

A simple variational formulation for contact dynamics is adopted to investigate the dynamic behavior of planar masonry block structures subjected to seismic events. The numerical model is a two-dimensional assemblage of rigid blocks interacting at potential contact points located at the vertices of the interfaces. A no-tension and associative frictional behavior with infinite compressive strength is considered for joints. The dynamic contact problem is formulated as a quadratic programming problem (QP) and an iterative procedure is implemented for time integration. Applications to analytical and numerical case studies are presented for validation. Comparisons with the experimental results of a masonry wall under free rocking motion and of a small scale panel with opening subjected to in-plane loads are also carried out to evaluate the accuracy and the computational efficiency of the formulation adopted.  相似文献

We present novel imaging results from a non-invasive examination of three ‘pattern-welded’ swords from the Viking Age belonging to the National Museum of Denmark, using white beam and energy resolved tomographies with neutrons. Pattern-welded blades are made by forge welding together thin strips of iron and steel that were twisted and joined in various ways, producing a decorative pattern on the surface. The study shed light on the inner structure of the composite material and manufacturing techniques of these admired examples of past technology, revealing some otherwise invisible details of their assembly methods, phase distribution and extent of the corrosion.  相似文献

The results of a petrographic and geochemical study carried out on archeological grindstones allow to provide new constraints on protohistoric commercial exchanges over the Mediterranean area. Eleven grindstones, discovered in an archeological site located in Milazzo (Messina, Sicily) and dated from the Early Bronze Age, have been investigated by geochemical and petrographic techniques. The raw materials are mainly volcanic rocks characterized by calc-alkaline and K-alkaline affinities with volcanic arc geochemical signature. Only one sample, made of basalt belonging to the Na-alkaline series, shows an intraplate signature. The comparison with the available literature data for similar rocks allowed constraining the volcanic origin of the exploited lavas. While the intraplate-type raw material came from Mt. Etna Volcano (Sicily), the arc-type volcanic rocks are mostly trachyandesites, basaltic andesites, and one rhyolite. Although most of them come from the Aeolian Arc, a provenance of some samples from the Aegean Arc cannot be excluded. This last region could represent the most probable provenance area for the rhyolite sample.  相似文献

Excavations of a kitchen at Escalera al Cielo in the Puuc Maya region of Yucatán, Mexico uncovered a concentration of fired clay balls (ca. 3–5 cm in diameter), in addition to other de facto domestic refuse. The kitchen pertains to an intensively excavated elite residential group that was rapidly abandoned sometime near the end of the Terminal Classic period (A.D. 800–950), resulting in floor assemblages that provide an opportunity to explore the types and distribution of daily household activities. The results of experimental replications and a suite of analyses comprising modal analysis, ceramic petrography, Fourier transform infrared spectroscopy (FTIR), and microbotanical residue analysis reveal aspects of clay preparation, firing temperatures, repeated use of the balls, firing conditions, and specific plant food or fuel residues adhering to them. We show that the fired clay balls were manufactured with local, clay-rich soil and employed by the inhabitants of Escalera al Cielo as heating elements; relatively high concentrations of microbotanical residues from edible plants adhering to them support the hypothesis that they were involved in kitchen activities related to food processing.  相似文献

This paper interrogates the relationship among visibility, distinction, international humanitarian law and ethics in contemporary theatres of violence. After introducing the notions of “civilianization of armed conflict” and “battlespaces”, we briefly discuss the evisceration of one of international humanitarian law's axiomatic figures: the civilian. We show how liberal militaries have created an apparatus of distinction that expands that which is perceptible by subjecting big data to algorithmic analysis, combining the traditional humanist lens with a post‐humanist one. The apparatus functions before, during, and after the fray not only as an operational technology that directs the fighting or as a discursive mechanism responsible for producing the legal and ethical interpretation of hostilities, but also as a force that produces liminal subjects. Focusing on two legal figures—“enemies killed in action” and “human shields”—we show how the apparatus helps justify killing civilians and targeting civilian spaces during war.  相似文献

The Eneolithic Cucuteni–Trypillia mega-sites were undoubtedly the largest residential agglomerates in southeastern Europe from c. 4100 to 3400 cal BC. Their sheer size and estimated population have triggered animated discussion of whether or not they should be regarded as ‘proto-cities’. Considering trajectories of change in, for instance, density of dwellings and settlement size, this paper discusses a series of issues that will help the reader decide in which category these large sites should be placed, while at the same time examining the arguments for and against Trypillia low-density settlement patterns, recently problematized by Chapman and Gaydarska (2016).  相似文献
