A Bayesian approach to rapid seismic vulnerability assessment at urban scale

The seismic vulnerability of city centers is commonly assessed by extending the study methods applied to single buildings to urban aggregations. This approach is not always applicable at territorial scale, as it is uneconomical in terms of time and costs. An innovative method provides reasonable large-scale a priori estimation of parameters not directly evaluable from the exterior of buildings by elaborating values which can be measured from the outside. Those parameters are treated as continuous variables, by assigning them a suitable probability density function. The Bayesian approach is adopted, which allows the update of initial hypotheses by using new data gathered during on-site surveys. In this regard, a rapid survey form for the on-site data collection is proposed. An example of its application to a façade of a building structural unit in Santo Stefano di Sessanio in L’Aquila province (Italy) is proposed, showing promising preliminary results for buildings belonging to Italian historical centers.     

Women helping women? Chain of command and gender discrimination at the workplace

ABSTRACT

We analyse the gender composition of the highest hierarchical levels within large Italian firms and we investigate whether it correlates to the working career of women in lower ranks of the same firm. We observe a disproportionate share of men hired and promoted, regardless of the top ranks’ gender composition. However, we detect a mitigating effect when the presence of women in higher managerial ranks increases promotions of women in lower ranks. This is consistent with the “women helping women hypothesis”. However, this mitigating effect is far from rebalancing career chances by gender. No significant differences emerge between firms in innovative and traditional sectors, despite the quite different narrative put in place by HR managers.     

Age of the final Middle Palaeolithic and Uluzzian levels at Fumane Cave,Northern Italy,using C,ESR, U/Th and thermoluminescence methods

This article presents and discusses the chronological layout of the final Mousterian and Uluzzian levels of Fumane Cave in northern Italy using ¹⁴C, ESR and TL methods. Given its complex sedimentary and cultural succession, Fumane is a key site to assess the Middle–Upper Palaeolithic transition in Southern Europe and to explore Neanderthal behaviour and to compare it with the first Aurignacians. Large ranges defined by the ESR and TL dates cover the radiocarbon ages for units from A11 to A4, respectively, from 42.8 to 32.5 ka BP become progressively younger in agreement with the stratigraphy, despite high dispersions within the same unit. Our estimates using chronometric data seem to support the hypothesis that the sequence may cover almost 10,000 radiocarbon yr and that from comparison with the sedimentological and palaeoecological data, the late Middle Palaeolithic and the early Upper Palaeolithic at Fumane occur in sediments formed under moderately cool to mild climatic conditions correlated to the Hengelo-Interstadial, shifting towards cooler and drier conditions. Finally, comparisons between the Fumane data set and other sites in the North-Adriatic region are discussed.     

Enterprise Clusters and Industrial Districts in Colombia's Fashion Sector†

This paper presents the theory of enterprise clusters and industrial districts, and contrasts it with the evidence of two productive agglomerations in the fashion sector in Colombia. The empirical evidence on Bucaramanga and Medellín, that host the largest groups of Colombian textile and clothing producers and exporters, is based on a survey questionnaire, carried out in November–December 1998. The results of the survey confirm the relevance of the Industrial district concept in understanding the recent developments of Colombia's textile and garments industry, and reveal the presence of some dimensions of an enterprise cluster in both Medellín and Bucaramanga, although each with different characteristics. However, both Colombian clusters are characterized by a low degree of firm–level specialization and poorly–developed enterprise networks. This is similar to what has been observed in most enterprise clusters in Latin America, and may clearly hinder the local external economies and collective efficiency. Backward linkages are poor or lacking in both clusters. The strategy prevailing in most enterprises has been the internalization of many stages of the productive process. Forward linkages are much stronger, and the retailers play a crucial role in the commercial phases. However, only Bucaramanga firms have entered global production and marketing networks, whereas Medellín firms are mainly oriented to the national market. Moreover, the two clusters have developed under very different economic policy regimes, and this had had its consequences on the clusters' performance and structure.     

Structural Assessment of Companhia Aurífícia,a 19th Century Industrial Building Located in Northern Portugal

Companhia Aurifícia is located in Porto, Portugal, and was founded in 1864. It was a pioneer factory in the industrial production, casting, rolling, and stamping of metallic objects and laboured for about 150 years, in areas as jewelry, manufacture of parts in silver and gold or the production, and casting of various metals. In 1866, it began laboring in Rua dos Bragas, its present location, and in 2003 ceased all activities.Companhia Aurifícia is an industrial complex including several buildings, all located in the same block. It is a precious example of the industrial architecture in Porto, where the still existent retaining walls, structures, machinery, and decorative elements make it one of the last examples of 19^th century industrial life of the city.This article aims to evaluate the safety condition of one of the buildings included in this industrial complex, in order to propose the necessary strengthening interventions.     

Making History, Talking about History

Making history—in the sense of writing it—is often set against talking about it, with most historians considering writing history to be better than talking about it. My aim in this article is to analyze the topic of making history versus talking about history in order to understand most historians' evident decision to ignore talking about history. Ultimately my goal is to determine whether it is possible to talk about history with any sense.
To this end, I will establish a typology of the different forms of talking practiced by historians, using a chronological approach, from the Greek andRoman emphasis on the visual witness to present-day narrativism and textual analysis. Having recognized the peculiar textual character of the historiographical work, I will then discuss whether one can speak of a method for analyzing historiographical works. After considering two possible approaches—the philosophy of science and literary criticism—I offer my own proposal. This involves breaking the dichotomy between making and talking about history, adopting a fuzzy method that overcomes the isolation of self-named scientific communities, and that destroys the barriers among disciplines that work with the same texts but often from mutually excluding perspectives. Talking about history is only possible if one knows about history and about its sources and methods, but also about the foundations of the other social sciences and about the continuing importance of traditional philosophical problems of Western thought in the fields of history and the human sciences.     

The use of white marbles for sculpture in Roman Gortyn (Crete) as revealed by archaeometric analyses

Gortyn was an important Cretan town from the late Archaic to the Hellenistic period and then became one of the provincial capitals of the Roman Empire. It controlled the whole of Crete and Cyrenaica and was a flourishing centre of trade and agricultural products in the first centuries of our era. In more than 100 years, many portions of the Greek and Roman town were unearthed under the supervision of the Italian Archaeological School of Athens and a considerable number of stone artefacts found, many of them made of imported marble since the local variety was grey and of poor quality. Statuary and other prestigious marble sculpted artefacts found in Gortyn were sampled and subjected to archaeometric examination (by way of optical microscopy in thin section, powder X-Ray diffraction and mass spectometry for the determination of the C and O isotopic ratio) in order to identify the quarries they came from. The results obtained from the analysis of several dozen white marble objects have indicated the use of a quite wide variety of species including Parian (from Lakkoi), Pentelic, Thasian (dolomitic and calcitic) and (occasionally) Proconnesian marbles. The first three, especially Pentelic, were used for most of the statuary.     

Imagining Kawthoolei: Strategies of petitioning for Karen statehood in Burma in the first half of the 20th century

Academic and media writing about the Karen ethnic group in Myanmar most often associates the group with war and insurgency. This article focuses instead on the different strategies and rhetorical arguments––and the ideological notions that underpinned them––adopted by the Karen in their informal and formal petitions for recognition and statehood from the early decades of the 20th century, through the Second World War, to the mid‐1950s, including previously unexamined evidence of an early Karen attempt to gain UN recognition. In following these efforts, we track imaginings of Karen nationhood over time through shifting and conflicting territorial claims and persistent, multifaceted diplomatic attempts to realize the material existence of the Karen homeland, Kawthoolei.
