Reading between the lines: δ18O and δ13C isotopes of Unio elongatulus shell increments as proxies for local palaeoenvironments in mid-Holocene northern Syria

The much debated link between the collapse of urban centres in northern Syria and climate change at the end of third millennium bc is arguably one of the best known cases about human societies' struggle with the unpredictable nature of the Holocene. Fine-grained analyses of bioarchaeological materials offer excellent opportunities to overcome some of the difficulties encountered in such studies that tackle the effects of changing environmental and climatic conditions on human civilisations during the Holocene. This paper explains the results of a pilot study that uses archaeological freshwater clams (Unio elongatulus) from northern Syria as intermediary anthropobiogenic proxies to infer about the seasonal rhythms of local pluvial regimes and their possible fluctuations at the turn of the third millennium bc. Having secreted their CaCO₃ in chemical and periodical accordance with the ambient environment and ending up at tell sites through human activity, these bivalves are suitable vessels of information about human ecology in northern Syria at the end of third millennium bc. Marked differences were observed between the isotopic (δ¹⁸O and δ¹³C) compositions of shells from Tell Mozan, an urban site that continued to exist throughout the rapid climate event, and those from Tell Leilan, which went into hiatus at the end of third millennium bc. These results have important implications about the potentially severe effects of micro-environmental differences on distinct human communities inhabiting the same culturally unified region.     

Impacts of Planners' Different Viewpoints on Optimum Land-Use Allocation

Development of different viewpoints/perspectives in the planning process and discussion of their empirical results will allow creation of “better land-use plans”. In this sense, one of the deficiencies met by the land-use planners is lack of decision support system that can analyse the empirical results of different viewpoints analytically. The aim of this study is to analyse impacts between planners' different viewpoints and the optimum land-uses allocation empirically and analytically. The study uses a generalized land assignment model formulated by Hanink and Cromley (1998) [Land-use allocation in the absence of complete market values, Journal of Regional Science, 38(3), pp. 465–480] that integrates the geographical information systems with multi-criteria decision-making techniques in Cesme/Izmir in Turkey. The study results indicated that the model is very useful to analyse impacts between planners' viewpoint and optimum land-use allocation.     

Transient and Long-Term Changes in Seismic Response of the Natural Resources Building,Olympia, Washington,due to Earthquake Shaking

The Natural Resources Building (NRB) in Olympia, Washington, was shaken by three earthquakes (Mw = 5.8, 6.8, and 5.0) between 1999 and 2001. Building motions were recorded on digital accelerographs, providing important digital recordings of repeated strong shaking in a building. The NRB has 5-stories above grade with 3 sub-grade levels and a ductile steel-frame elongated in the E-W direction. The upper two floors extend significantly beyond the lower 3 on the southern and eastern sides. N-S motions dominate the fundamental modal vibrations of the building system. In the 1999 Satsop M5.8 earthquake, the frequency of this fundamental system mode was 1.3 Hz during motions of 10% g. The frequency dropped to 0.7 Hz during the 2001 M6.8 Nisqually strong motions. Moreover, the Nisqually recordings reveal both numerous high-frequency transients of up to 0.18 g, several of which are visible on widely spaced sensors, and long-term tilts of some of the sensors. The weaker 2001 M5.0 Satsop earthquake motions showed the frequency remained depressed at less than 1 Hz for the eastern side of the structure, although the western side had recovered to 1.3 Hz. An ambient noise survey in 2008 showed the fundamental frequency of N/S vibrations remains about 1.0 Hz for the eastern side of the building and 1.3 Hz for the western side. These results suggest that in the Nisqually earthquake, the east side of the NRB suffered a permanent reduction in fundamental mode frequency of 37% due to loss of system stiffness by undetermined mechanism.     

Examining the Impact of Turkey's Approach Vis‐à‐Vis Syria into Turkey's Iraq Policy

The tension between “international order” and justice has long been a focus of critical attention of many scholars. Today, with the rise of the humanitarian crises, the debate is once again visible, and Turkish foreign policy is one of the most important areas of observation of this tension. Indeed, the U.S.‐led invasion of Iraq in 2003 paved the way for Turkey to actively engage in regional affairs. Meanwhile, the need to bring human justice into world politics makes Turkish foreign policy decision makers operate on a much more humanitarian basis. Nevertheless, active humanitarian engagement poses an important challenge to traditional Turkish foreign policy as it is mainly based on the notion of “non‐interference,” as well as on the elementary components of international order, by raising suspicions on the intentions of the Turkish authorities. This article aims to explore the challenges Turkey has been facing since the U.S.‐led invasion of Iraq, and diagnose Turkish foreign policy vis‐à‐vis Iraq in the shadow of the Syrian civil war from Hedley Bull's framework of “order” and “justice.” It argues that Turkey's recent fluctuations in the Middle East could be linked to Turkey's failure to reconcile the requirements of “order” with those of “justice” and the Turkish governing party's (AKP) attempts to use justice as an important instrument to consolidate its power both in Turkey and in the Middle East.     

Tropes of fear and the crisis of the west: Trumpism as a discourse of post-territorial coloniality*

We examine ‘Trumpism’ as a contemporary form of colonial domination, showing how this discourse represents both a crisis of coloniality and a stimulus for a movement of ‘decoloniality’. A critical discourse analysis is applied to seven speeches delivered by Donald Trump between his announcement of his presidential candidacy in June 2015 and his inauguration in January 2017. In assessing Trump's arguments, we focus mainly on those concerning national security, illegal immigration, and the threats posed by various foreign countries. Although these arguments sit within a long colonial tradition, they also indicate a crisis of modernity, as witnessed in the growing challenges to colonial masculinity, nationalism, and rationality. We conclude that Trumpism articulates a reaction to these challenges, and that Trump's rise to power is a symptom of the crisis of post-territorial coloniality in contemporary global society.     

Rural Agricultural Economies and Military Provisioning at Roman Gordion (Central Turkey)

Roman Gordion, on the Anatolian plateau, is the only excavated rural military settlement in a pacified territory in the Roman East, providing a unique opportunity to investigate the agricultural economy of a permanent Roman garrison. We present combined results of archaeobotanical and zooarchaeological analyses, assessing several hypotheses regarding Roman military provisioning. The garrison adapted its dietary preferences to local agricultural systems, but maintained its traditional meat supply of pork, beef, and chickens as well. There is evidence for economic interdependence with local farmers and cattle herders, self-sufficiency in pork and chicken production, and complex relationships with autonomous sheep and goat herders who pursued their own economic goals. If the Roman military in Gordion exercised a command economy, they were able to implement that control only on specific components of the agricultural sector, especially cereal farming. The sheep and goat herding system remained unaltered, targeting secondary products for a market economy and/or broader provincial taxation authorities. The garrison introduced new elements to the animal economy of the Gordion region, including a new pig husbandry system. Comparison with contemporary non-military settlements suggests both similarities and differences with urban meat economies of Roman Anatolia.     

Window opening effects on structural behavior of historical masonry Fatih Mosque

Structural walls of old historical structures are either blind or have openings for functional requirements. It is well known that in and out of plane responses of structural walls are affected by the size, locations, and arrangements of such openings. The purpose of this investigation is to study the window opening effects on static and seismic behaviors of historical masonry old mosques. Fatih Mosque, which was converted from a church, constructed in 914 in Trabzon, Turkey, is selected for this purpose. The mosque is being restored. Structural exterior walls of the mosque were made using stone and mortar materials. When the plaster on the walls was removed during the restoration, 12 window openings were found as blind on the exterior structural walls of the mosque. Within the scope of restoration works, it is aimed to open such blind windows. In order to investigate the effects of the window openings on the structural behavior of the mosque, 3D solid and finite elements models of the mosque with and without window openings are initially developed. The experimental dynamic characteristics such as frequency, damping ratio, and mode shapes of the current situation of the mosque, where some windows openings are blind, are determined using Ambient Vibration Testing. Then, the finite element model of the current situation of the mosque is updated using the experimental dynamic characteristics. The static and seismic time history analyses of the updated finite element model with and without window openings are carried out. Structural behaviors of the mosque with and without window openings are compared considering displacement and stress propagations.
