Space and Identities at the South Eastern European Frontier
No full textIn this chapter, which is part of a larger collection on the issues of sustainable tourism and transport development in the Adriatic-Ionian region, Emilio Cocco discusses the notion of “frontier” with regards to the Adriatic-Ionian space. The concept of frontier is consider both for its ecological and social implication; thus, like all geo-morphological diversities, also the ones included in the notion of frontier are not just geographical phenomena but do mark symbolic differences and engender identity-making processes. The discussion starts with the critical reassessment of the 19th century natural borders theory, whereby the idea of natural border was interpreted as a metaphisical and predestined ideal to conquer and achieve, thus prolonging the illusion of a true natural order.
Differently, from a sociological point of view, the author points out that the course of nature performs the function of support for cognitive social conventions. And these conventions, in turn, operate a a symbolic and mythical level, mainly bringing about implications for the settlement of the social order. In thsi perspective, which owns mostly to the revised functionalist framework of the anthropologist Mary Douglas, the symbolistation of the space is just one of the means to establish social unity and not necessarily the expression of the unity itself. And a realisation of a territorial order within certain geographical limits can only occur through a symbolic reiteration of their “naturalness”, as suggested by Marc Augé. For that reason, Emilio Cocco, addresses the problem of the troubled relations between territoy and society in Socuth-Eastern Europe by referring to the notions of spatiality (J. Agnew) and territoriality (Tuathail, Luke), which are important to disintangle the concepts of space and territory. Thus, these reflections are reversed into a concept of frontier that should work conceptually to explain the many typical conflicts of South Eastern Europe, where interactions between space, territory and identity are carachterised by frequent reference to the defence/preservation of a social identity. Consequently, Emilio Cocco articulates his discussion of the notion of frontier applied to the South Eastern European context by analysing and comparing a number of theoretical scholary work. Eventually, he makes an attempt to sketch out the dynamics of exlcusion and inclusion acording to the paradigm of cultural frontier. Eventually, he suggests that the notion of frontier could work both as a scholary and as a policy tool to challenge the problems of social conflict in South Eastern Europe

Structural Survey and Empirical Seismic Vulnerability Assessment of Churches in the Historical Center of Cusco
No full textThe seismic vulnerability assessment of buildings represents a fundamental step for seismic risk prevention and mitigation, especially in seismic-prone areas where severe damage scenarios are expected or where valuable assets are present. The city of Cusco, whose historic center has been a UNESCO World Heritage site since 1983, has a long list of seismic events that caused extensive damage. Being part of the international heritage, churches are characterized by great architectural and cultural value, and their preservation is crucial. In this paper, the seismic vulnerability assessment of churches within the historic center of Cusco is presented. The assessment is made through a two-step process. First, data on churches are collected with a structural survey at the urban scale. Second, collected data are used to determine the seismic vulnerability with an empirical method that combines field observations and engineering judgments. The most vulnerable churches in the city center are identified, and their primary structural deficiencies are determined through this process
DETERMINATION OF THE MISCIBILITY GAP IN THE Al-Be SYSTEM BY RESISTIVITY MEASUREMENTS AND X-RAY ANGLE SCATTERING.
No full textThe high-solute concentration branch of the coherent miscibility gap for the Al-Be system has been determined by combining resistometric and SAXS results. The analysis of SAXS curves indicates that G. P. zones are platelets, a shape that is in agreement with anisotropic elasticity considerations
Seismic vulnerability of buildings in historic centers: From the “urban” to the “aggregate” scale
No full textSeismic vulnerability assessment of urban centers is a challenging issue that needs to be faced accurately for the earthquake risk of large territorial areas. The selection of suitable methods is a crucial aspect that must be treated according to different evaluation processes, depending on the size of the problem and on the available calculation capacities. A possible strategy consists in analyzing large stocks of buildings, so to include in the analyses all those structural parameters that characterize their response and to involve the variability of the considered features. This would require a high computational effort that should be addressed to the investigation of the response of a large number of models. For this reason, simplified procedures based on engineeristic judgements, are commonly considered a viable way to be undertaken in order to predict damage scenarios. Alternatively, the attention could be focused on a limited number of buildings that are judged to be representative of the whole stock. In this case, more sophisticated analyses could be carried out and the obtained results could be extended to the whole urban center. Based on this premise, this paper presents the results obtained through the application of two different seismic vulnerability methodologies on the historic center of Campotosto, in Italy, which was hit by the last 2016 Central Italy earthquake. The first is an empirical method, applied considering a large stock of 130 buildings, which was calibrated by the authors after the 2009 L'Aquila earthquake for historical centers that are similar to the one studied in this paper. The latter, is a method based on analytical formulations dealt with by the Vulnus software, developed at the University of Padua in Italy, which was used for evaluating the seismic vulnerability of an aggregate building, which has been considered representative of the historic center. The final aim is to compare, also in the light of the damage provoked by the 2016 earthquake, the observed post-seismic scenarios, expressed in terms of fragility curves, derived from the two applied methodologies, in order to prove their reliability and to stress the possible issues related to their implementation at different scales
Adaptive cluster expansion for Ising spin models
No full textWe propose an algorithm to obtain numerically approximate solutions of the direct Ising problem, that is, to compute the free energy and the equilibrium observables of spin systems with arbitrary two-spin interactions. To this purpose we use the Adaptive Cluster Expansion method [S. Cocco, R. Monasson, Phys. Rev. Lett. 106, 090601 (2011)], originally developed to solve the inverse Ising problem, that is, to infer the interactions from the equilibrium correlations. The method consists in iteratively constructing and selecting clusters of spins, computing their contributions to the free energy and discarding clusters whose contribution is lower than a fixed threshold. The properties of the cluster expansion and its performance are studied in detail on one dimensional, two dimensional, random and fully connected graphs with homogeneous or heterogeneous fields and couplings. We discuss the differences between different representations (Boolean and Ising) of the spin variables
Lymphadenopathy after the anti-covid-19 vaccine: Multiparametric ultrasound findings
No full textBackground: Post-anti-COVID-19 vaccine lymphadenopathy has recently been described in the literature. In this study, we investigated the multiparametric US findings of patients with post-vaccine lymphadenopathy and compared these findings among different anti-COVID-19 vaccines. Methods: We retrospectively evaluated 24 patients who underwent US between January and May 2021 due to post-anti-COVID-19 lymphadenopathy. The presence, size, location, number, morphology, cortex-hilum, superb microvascular imaging (SMI) and elastosonography of lymph nodes were assessed. Descriptive statistics were calculated and differences among anti-COVID-19 vaccines were analyzed using the Kruskal–Wallis test. A p-value ≤ 0.05 was considered statistically significant. Results: Sixty-six nodes were assessed. They were axillary (mean 1.6 cm ± 0.16) in 11 patients (45.8%) and supraclavicular (mean 0.9 cm ± 0.19) in 13 patients (54.2%). In 20 patients (83.3%), the number of nodes was ≤3. Prevalent US features included oval morphology (18, 75%), asymmetric cortex with hilum evidence (9, 37.5%), central and peripheral vascular signals (12, 50%) at SMI and elastosonography patterns similar to the surrounding tissue (15, 71.4%). No significant differences among the three anti-COVID-19 vaccines were observed (p > 0.05). Conclusions: Anti-COVID-19 vaccines may present lymphadenopathy with “worrisome” US features regarding size, shape, morphology, cortex-hilum, SMI and elastosonography. An awareness of the patient’s history and US findings may help in the early recognition of this clinical scenario and in the appropriate selection of patients for a short-term US follow-up
