Dynamical Assessment of the Work Conditions of Reinforcement Tie-Rods in Historical Masonry Structures

Tie-rods are essential structural elements, which have been employed for centuries in masonry historical buildings, either during the construction or in successive strengthening interventions, with the aim of containing dangerous horizontal actions. The actual work conditions of these tie-rods, which are strongly influenced by their load history, are difficult to be quantified theoretically, and an effective method for their measure is of great importance in order to ensure the efficiency of these elements during the time and the stability of the entire building. Common measurements are often carried out adopting models based upon significant simplifications, like, for example, hinges at the extremities. These assumptions, rarely represent the real work conditions for anchorages. In this work, a non-destructive testing method is presented, based upon sophisticated dynamical models that can take into consideration many of the circumstances neglected by the simplified models. Four case studies are extensively described, trying to embrace the most common situations in term of peculiar features of the building, structural configuration, and load history. The discussion of the results yields the safety margin of the rod with respect to the material failure and provides important indications about the overall stability of the whole building.     

Approaching the archaeology of value: a view from the modern world

SUMMARY: The abundance of goods in the modern world has a tendency to prejudice interpretation of their value, but the way people value their goods is complex, relative and changeable — scarcity is just one factor. There is a long history of value theorization across the social sciences, but archaeological considerations of value remain uncommon and focused on prestige goods. In this paper, I review alternative conceptions of value through the lens of the modern world, with an example of Spode creamware used by a governor in the early decades of colonial Sydney. I argue that the process of devaluation, through discard and waste, offers a unique archaeological understanding of the shifting values people of the modern world placed on commodities.     

The early Ottomanization of urban Cyprus

SUMMARY: In 1571, the Ottomans completed the conquest of Cyprus. In order to consolidate their new territory, the Ottomans introduced a policy of imperial control that was centred on local accommodation and negotiation to facilitate stable governance. This study examines the process of the conquest and the extent to which the conquest changed the character of the urban landscapes of Cyprus. Architecture and urban reshaping represented a central facet of this process of colonial change and introduced a new visual language of control and Islamic presence. Nicosia was established as an administrative provincial capital and underwent redevelopment that followed an urbanscape replicating core features of an Ottoman town. This pattern of redevelopment was replicated elsewhere across the island as its economic infrastructure was strengthened. However, this period remains contested within the context of contemporary conflict on the divided island.     

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).     

Long-distance provenance for obsidian artifacts of Mesoamerica Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park (Honduras)

Los Naranjos is one of the most important pre-Columbian human settlements of Honduras related to the south-easternmost border of the Mayan civilization. Although the archaeological site mostly spans from 850 BC to 1250 AD, the present obsidian study was only focused on the Preclassic and Early Classic periods (Jaral, 800–400 BC and Edén, 400 BC–550 AD) where undamaged blades and/or retouched obsidian flakes are rare. In this way, the INAA analyses of 17 obsidian samples, compared with major-trace elements data of Honduran and Guatemalan obsidian sources, are mostly representative of waste flakes. Lithic artifacts of Los Naranjos such as sandstones, basalts, and quartzites come from local geological outcrops; whereas, obsidian provenance has to be searched from sources which are located within a radius up to 300 km far away. San Luis, La Esperanza, and Güinope obsidian sources are located in Honduras while the three most exploited Highland Guatemalan obsidian outcrops, which have been dominating long-distance trade in the Maya area mostly for the Classic-Postclassic periods, are San Martin de Jilotepeque, El Chayal, and Ixtepeque. An Ixtepeque provenance, for all the investigated obsidian samples of Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park, was established, thus emphasizing a long-distance source (180 km). This also confirms that Ixtepeque represents the most important provenance of the obsidian artifacts found in archaeological sites of Western and Central-Western Honduras. The possible role played by some of the most important rivers of Guatemala and Honduras as waterway networks of transport was finally pointed out. New INAA chemical data from the Honduran obsidian source of La Esperanza (“Los Hoyos”, 4 samples) are also reported in this paper.     

Governance in Multi-Project Networks: Lessons from a Failed Destination Branding Effort

Abstract

This article describes and analyses the process in which the establishment of a Christmas market led to an attempt to establish a regional destination brand named “Delightful Christmas”. Our focus is on the network dynamics of the process, in particular its multi-project network characteristics. Empirical findings are based on qualitative data from personal interviews, participant observation and documentation in an action research approach. The process is analysed as a so-called project network (Hellgren & Stjernberg, 1995 Hellgren, B. & Stjernberg, T. (1995) Design and implementation in major investments—a project network approach, Scandinavian Journal of Management, 11(4), pp. 377–394. doi: 10.1016/0956-5221(95)00020-V[Crossref] , [Google Scholar]) involving different actors having different aims in event and destination brand development, thus creating a process with actors of existing, but resource-lacking, dependencies. Despite the disagreements between actors, the common beliefs and hopes for the integrated destination theme remained and innovative work continued for about three years in an environment where conditions were difficult due to insufficient financial resources, project coordination and long-term strategic planning. Conclusions concern the dynamics of a complex multi-project network organization and how its failure can be explained.     

The Mundane and the mystic: Constructions of human relations with the animal world in Brunei-Dusun and other Bornean folktales

The paper offers a broad six-part classification not only for the animal tales of the Brunei-Dusun (see E.M. Kershaw's 1994 collection) but also for a considerable amount of cognate material collected by British and Dutch scholars in Sarawak, Sabah and Kalimantan. The main categories proposed are: I. Anthropomorphic interaction among animals, and between animals and humans; II. Birds and animals as messengers and helpers; III. Mockery of animals incurs a curse; IV. Animals turned into (or restored as) miraculous humans upon a chance stimulus, or through beneficial treatment by a human of high virtue; V. Dusun and crocodiles showing reciprocal respect in modern times, or evincing transmutable identity in the past; VI. Wild-boars transformed into humans (en masse). In the Brunei-Dusun section each category is followed by one tale in English translation, for illustration. What emerges from ‘between the lines’ of this literature is an ideology which does not classify humans as a species so distant from other animals as western, let alone Muslim, thought would have it, nor that is set far above the jungle creatures in status and power.
