Towards lower carbon cities: urban morphology contribution in climate change adaptation strategies

Non-urbanized areas (NUAs) play an important role in reducing the effects of climate change by providing both carbon storage and sequestration. Urban areas are responsible for the emission of 60% of global greenhouse gas, 50% of which are produced by buildings. During the past decades, increasing urban growth and sprawl processes produced several urban layouts characterized by different morphological features and a common lack of sustainable energy and environmental solutions. Investigating the relationship between urban morphology, energy demand and carbon emission/sequestration represents a relevant topic for urban planning practices implemented to face urban climate change effects. This study proposes a method for a transformability assessment aimed at investigating the transformation suitability of different urban morphology types. The case study is the metropolitan area of Catania (Italy), characterized by an impressive urban growth since the 1960s. The proposed method identification of limits and options for increasing sustainability of urban areas considering the contribution of both NUAs and built-up areas. This approach allows to identify appropriate planning tools for new layouts of urban fabrics while increasing the objectivity of the decision process. In the framework of climate change mitigation and adaptation, the outcomes of this research may lead to innovative urban planning practices.     

Thrust network analysis of masonry helical staircases

We exploit a recent generalization of the Thrust Network Analysis (TNA) to analyse masonry structures of extremely complicated and audacious geometry such as helicoidal staircases. Actually, differently from available methods, based on ad-hoc solutions holding for each particular structure, the TNA allows for studying the equilibrium of structures of arbitrary shape by invoking the principles of limit analysis of masonry structures dictated by Heyman. Four paradigmatic monumental staircases, with increased degree of complexity, have been selected as case studies in order to show the versatility and accuracy of the proposed approach. The results entailed from the generalized TNA are also successfully compared, for the first time in the literature, with those related to the adoption of available analytical methods for the analysis of no-tension membranes.     

Museums as Societal Engines for Urban Renewal. The Event Strategy of the Museum of Natural History in Florence

Abstract

The paper aims to contribute to the debate on urban renewal, departing from the so-called Bilbao effect. Focusing on the resurgence of a societal function of cultural heritage, we discuss the idea of the museum as a societal engine through a case study. Although the literature has been mainly dedicated to assessing the economic impact of large art museums in former industrial regions, the paper focuses on a small scientific museum, the Museum of Natural History in Florence, and on its strategy of social enhancement through the organization of small- and medium-sized cultural events in the historical city centre. Through the application of social network analysis to 17 temporary exhibitions between 2000 and 2012 and the analysis of 790 events divided into three macro-areas (relations with territory, educational networks and scientific networks), the role played by the museum, the density and variety of events will be investigated. The resulting picture is that of a proactive museum located at the centre of a network of—mostly local—institutional actors that have effectively contributed to the re-vitalization of scientific knowledge and education as well as relations with the citizenship and the territory, therefore representing a valuable example of a societal enhancement of culture.     

The Art of Taphonomy and the Taphonomy of Art: Layer IV,Molodova I,Ukraine

Level IV of Molodova I, an open-air Middle Paleolithic site in the Ukraine has been described by some researchers as a possible source of evidence for early symbolic behavior. We examined bone objects from this layer that were identified by Ukrainian researchers as exhibiting possible Neandertal produced engravings including two anthropomorphic figures. While we have determined that there is no evidence of symbolic activity at Molodova I, the database we have created, with its systematic recording of traces left by taphonomic agents on faunal remains, provides a better understanding of the overall site taphonomy.

Beyond Boundaries: Nature,Culture and a Holistic Approach to Domestication in the Levant

The main objective of this paper is to suggest an alternative approach for the investigation of domestication in the Levant. First, basic data regarding domestication in the Levant are presented. Then the various traditional approaches towards domestication in the prehistoric Levant, labeled (1) environmental, (2) social and anthropological, and (3) cognitive, are briefly reviewed. This discussion forms the basis for a proposal of a “holistic approach,” in which domestication is regarded as a long-term, multidimensional and multirelational phenomenon, including many elements—such as plants, animals, humans, material culture and ancestors—with increasing human manipulation of these various constituents. After a presentation of the theoretical framework, a growth metaphor is used to reconstruct the process of domestication (ca. 20,000–6500 B.P.) as a number of phases: (1) germination in the Kebaran; (2) development in the Early Natufian; (3) retreat/dormancy in the Late/Final Natufian; (4) growth in the Pre-Pottery Neolithic A; (5) florescence in the Early- and Middle Pre-Pottery Neolithic B: (6) further development in the Late Pre-Pottery Neolithic B; (7) dispersal in the Final Pre-Pottery Neolithic B and the Pottery Neolithic. In each of these phases, relations between the various elements are dealt with, special attention being paid to symbolical relations, as evidenced by “art” and ritual.     

An Alternative Way Towards Food Production: The Perspective from the Libyan Sahara

Food production originated in various ways in different parts of the world. Plant domestication with the adoption of agriculture has been successful in some areas, but not in others, where animal domestication with nomadic pastoralism proved to be more effective. Likewise, the preceding phases of pre-adaptation and development of a broad spectrum of wild resource exploitation followed different pathways, according to the locally available resources, climatic and geographic conditions, and social organizations. Northern Africa greatly contributed to the understanding of the origin of food production under preconditions that differed from those in the Fertile Crescent. Apart from a narrow strip along the Nile valley, northern African lands are arid and scarcely productive for agriculture. Nevertheless, early studies interpreted northern African archaeological records of the Early and Middle Holocene according to the traditional north-western Mediterranean and Near Eastern frames of reference. Consequently, terms such as Epipalaeolithic, Mesolithic, and Neolithic were uncritically applied to northern African contexts. This paper compares and discusses the evidence for food production in the Near East and northern Africa, considering the question of introduction or local breeds of domesticated animals in the Maghreb and the Sahara. It then reviews the relevant data for long-held diffusionist models of pastoralism into Africa to provide a different perspective and the proper means of interpretation of the northern African archaeological records. Finally, it examines some recent findings from the Tadrart Acacus, in the Libyan Sahara, which contribute to clarification of distinctive African pathways and propose an alternative model for the beginnings of food production.     

Émile Meyerson,d'après sa correspondance

Building upon Emile Meyerson's correspondence and other personal papers, all of them hosted by the Central Zionist Archives in Jerusalem, this article presents a mainly personal portrait of the philosopher (1859–1933). Thus this article describes his family circle in Lublin (Poland), his higher education (in Germany) and his professional course: settled in France, he worked first in chemistry, then get a job as foreign news editor and later took an important position at the Jewish Colonization Association. This article deals also with Meyerson's contacts with the French and international intellectuel milieu (scientists as well as writers).     

Singulières archives

Archives, although fundamental to historical research, are rarely appreciated in terms of their place in epistemology. The concept of «archive»-usually given in the singular-has, however, been treated by several philosophers, including most recently Paul Ric?ur. This paper focuses on Ric?ur's latest work,La Mémoire, l'histoire, l'oubli, to analyse Ric?ur's use of the term «archive» and its resonances with the work of Michel Foucault and Michel de Certeau. It investigates, as well, how the concept of archive, closely linked to that of witnessing or testimony, presents certain difficulties from the vantage point of historical epistemology, and proposes another use of the term, one involving greater attention to the historicity and materiality of the «archive» in the interests of a more textual and hermeneutic interpretation.     

The Irish Sí Tradition: Connections Between the Disciplines,and What’s in a Word?

One of the most prominent features of the Irish landscape is the great multitude of megalithic sites which date back to the Neolithic. In this paper, I will attempt to demonstrate that the understanding of these sites in Ireland can be enhanced by referencing the native tradition, including the Irish word for the sites, sí, and the sís powerful cultural tradition attested to throughout native Irish folklore, literature, onomastics, and traditional knowledge. In doing so, I will explore the difficulties and the potentials of interdisciplinary communication between archaeology and folkloristics, and the related issues regarding communication between official and unofficial discourses.
