Hub Location Problem with Allowed Routing between Nonhub Nodes

In this study, we relax one of the general assumptions in the hub location literature by allowing routed flows between nonhub nodes. In hub networks, different flows are consolidated and routed via collection, interhub, and distribution arcs. Due to consolidation, some flows travel long paths despite closeness of their origin and destination. In this study, we allow direct flows by penalizing by a scalar factor of original cost of transshipment between these arcs. We present mathematical models for median, center, and set covering versions of the problem for single‐ and multi‐allocation cases. We test the models with the CAB and TR data sets. We discuss the properties of established direct connections for different models by using another mathematical model where the number of direct flows is bounded and interpret the effect of changes in problem parameters.     

Assessment of Construction Techniques and Material Usage in İzmir Rural Houses

The domestic architecture in the rural villages of ?zmir comprises a unique built environment with their masonry wall textures, semi-open sofas, round tiled-hipped roofs, and chimneys, and represents an important part of the cultural and architectural heritage. This assessment is mainly based on field observations that focus on the architectural and structural layout of intact, damaged, and destroyed houses. During field observation and the analysis of data certain plan typologies and relationships between the geological formations of the region and choice of materials and construction techniques were observed. While load-bearing masonry and timber skeleton systems are common, extensive use of timber laces, stone, and fired or adobe brick masonry with mud mortar and timber frames infilled with masonry materials were frequently seen. Generally, round timber elements such as wall plates, laces, lintels, posts, and frames of flooring systems are used. Architectural degenerations in authentic houses, defective details and partially due to the earthquake-prone nature of the region seismicity have been evaluated. An overall approach for the preservation and sustainability of this heritage is suggested.     

The Balkan Wars and the rise of the reactionary modernist utopia in young Turk thought and the journal Türk Yurdu [Turkish Homeland]

The article examines the rise of the ‘reactionary modernist’ project that developed after the devastating defeat of the Balkan Wars and which was promoted by the Young Turks by means of articles published in Turkish Homeland, the intellectual platform of the Young Turks. The article argues that the outlines of this project to a large extent shaped the contours of Turkish nationalism then, and that they have hence been constitutive of Turkish nationalism ever since.     

Technical Note: Practical Challenges Facing the Selection of Conditional Spectrum-Compatible Accelerograms

There are various possibilities for the selection and scaling of ground motions for advanced seismic assessment of buildings using nonlinear response-history analyses. As part of an on-going project looking at building-specific loss assessment in Italy, this article highlights a number of challenges currently facing the use of conditional spectra for ground motion selection in practice, essentially related to the limited amount of seismic hazard information that is publicly available. To illustrate the points being made, the challenges faced when trying to develop conditional spectra and select spectrum-compatible accelerograms for a rock site in Napoli, Italy, are described and the seismic assessment results obtained for a number of reinforced concrete wall structures are presented. Aside from providing practitioners with an appreciation of the potential difficulty associated with using conditional spectra for record selection, this technical note should also motivate national authorities to provide more background information on national seismic hazard data and detailed guidance for record selection.     

Between science and empire: the diplomatic struggle over Mesopotamian antiquities in Lisbon (1914–1926)

A powerful curiosity to discover the ancient world – reaching its peak in the nineteenth century – led to British, French, and German museums to enhance their collections with a great number of Mesopotamian antiquities. Most of these were the product of excavation work, which took years, followed by a shipping process fraught with hurdles and delays – much as when Babylonian and Assyrian antiquities were stranded in Portugal over the period 1914–26. In that case Portuguese officials seized the hoard of Babylonian and Assyrian items due to be sent to Germany at the beginning of the First World War by the German Oriental Society, which had carried out excavation works in Ottoman territories in the name of Kaiser II Wilhelm. The extensive British efforts and diplomatic exchanges aimed at bringing the pieces to London after the war, presents us with important clues regarding ownership disputes over antiquities, and the imperial struggle to acquire the cultural heritage of the near east. This study reveals that, under the existing legal framework, the items eventually taken to Berlin actually belonged to the Imperial Museum in Istanbul, and analyzes the discourse of ‘scientific concern’ constructed by British diplomacy.     

Towards an encompassing perspective on nationalisms: the case of Jews in Turkey during the Second World War, 1939–45

ABSTRACT. This article focuses on the plight of the Jews in Turkey during the Second World War, with the intention of analysing specific historical events through the lenses of leading theories of nationalism. First we review recent developments in historiography that contribute the framework for understanding both the hermeneutical possibilities and limitations when addressing historical texts. Then we employ three theories of nationalism – the ethno‐symbolist, instrumentalist and social constructivist – as a means of analysing and interpreting the historical events of the Jewish predicament vis‐à‐vis the Republic of Turkey. We conclude by suggesting what impact our findings may have on the narratives from this time period, and the way in which we can understand narratives today.     

FTIR imaging and HPLC reveal ancient painting and dyeing techniques of molluskan purple

Fourier transform infrared spectroscopy and imaging coupled to optical microscopy, scanning electron microscopy coupled to energy dispersive x-ray spectroscopy and high-performance liquid chromatography (HPLC) coupled to diode-array detection are used to investigate two samples removed from a painted decoration of a burial kline and a textile fragment, both found in Koru tumulus (fifth century BCE) in Daskyleion. Tyrian purple and kaolinite were identified in both samples, thus suggesting that the aluminosilicate compound had an important role in the applied painting and dyeing processes. The textile fragment is composed of undyed cotton and silk yarns dyed with the molluskan dye. The relative compositions of the molluskan materials used in the two archaeological objects are similar and comparable with the corresponding composition measured for a purple sample originated from Murex trunculus mollusks according to the HPLC results. This result is supported by principal component analysis (PCA) which, furthermore, takes into account the relative compositions of the extracts of the three Mediterranean mollusks, published in previous reports.
