Expanding the plain: using archaeobotany to examine adaptation to the 5.2 kya climate change event during the Anatolian Late Chalcolithic at Çadır Höyük

This study examines how the population at Çadır Höyük on the north central Anatolian plateau modified agricultural and fuel use practices in response to rapid social and environmental change between 3600 and 2900 BCE (Late Chalcolithic and Transitional to Early Bronze periods). Using descriptive and multivariate statistics to explore data from 60 archaeobotanical samples spanning three periods of occupation (3600–3200 BCE, 3300–3100 BCE, and 3100–2900 BCE) the results reveal that the inhabitants of Çadır relied heavily on barley, emmer, lentils, and flax throughout the Late Chalcolithic. Both dung and wood were used as fuel, although dung fuel appears to have been preferentially used. The most significant change throughout this period was a shift from foddering animals to grazing animals on the steppe. This shift corresponded with the 5.2 kya event, a period of increased aridity at the very end of the 4th millennium BCE. By diversifying their agricultural strategies to more risk adverse practices, the population at Çadır demonstrated their ability to be resilient in the face of climate change.1. Introduction 2.

Editors Note

The Society for Comparative Cultural Inquiry at UCL (SCCI) is delighted to introduce the fourth issue of our postgraduate journal, Tropos. The papers included were all presented at the 2016 Conference, titled ‘Belonging and Transgression’. The papers addressed a wide variety of disciplinary interests in connection with the title theme, intended to allow a point of convergence for scholars from a number of eclectic intellectual backgrounds. The submissions each explored how notions of Belonging and Transgression could be understood and interpreted across a number of cultural, linguistic, and theoretical contexts. This edition of Tropos presents an exclusive selection of the papers presented at the conference, which in 2016 enjoyed its fourth year running. The conference was held at University College London on 23rd-24th June 2016 and was organised by members of the Society from both the School of European Language, Culture, and Societies (SELCS) and the Centre for Multidisciplinary and Intercultural Inquiry (CMII). It featured numerous postgraduate speakers from across the UK and Europe as well as keynote addresses from Professor Mairéad Hanrahan (Chair of French, UCL) and Professor John Sutherland (Emeritus Lord Northcliffe Professor of Modern English Literature, UCL) The research presented at the conference drew on a wide variety of disciplines, speaking to a range of different subjects as diverse as writings on the politics of AIDS/HIV in France, the 16th century legal discussions on the rights of free-movement of peoples, and mid-twentieth century Hungarian theatre. The conference stimulated lively discussions provoked by the theme and the different methods of addressing it throughout the papers. These conversations continued long after the formal proceedings concluded. We are delighted to share a selection of the papers from this conference with you in these pages, and we hope that a similarly lasting discussion will occur between you, the reader, and the articles in this third edition of Tropos. The conference series will continue in 2017 and organised by the Graduate Society for Comparative Cultural Inquiry

Influence of Deicing Salts on the Water-Repellency of Portland Cement Concrete Coated with Polytetrafluoroethylene and Polyetheretherketone

Sustainable super water/ice-repellent pavements are gaining attention as a smart solution for mitigating problems associated with winter pavement maintenance of roadways and airfields. Such smart pavements can facilitate surface drainage and prevent or curb ice formation or snow accumulation. While a conventional method for melting ice and snow is the use of deicing chemicals, such materials can transfer to the surface of nanotechnology-based pavements and influence their water/icerepellency by changing the chemistry of water or ice. This study focused on characterizing the degree of hydrophobicity of Portland cement concrete (PCC) nanocoated with polytetrafluoroethylene/polyetheretherketone (PTFE/PEEK). A layer-bylayer (LBL) spray deposition technique was used for spraying the binding agent and water-repellent materials. The liquid-repellency was characterized by measuring the static liquid contact angles (LCAs) and calculating the works of adhesion (WA). The liquid types used included distilled water and two types of deicing chemicals prepared by dissolving salts in distilled water. Data analysis results revealed that salt contamination improves the water-repellency of nano-coated surfaces

Regional patterns of transition at Çadir Höyük in the Byzantine period

Byzantine archaeological sites tend to be seen as representative of the empire as a whole, with little concern given to regional context. Within the imperial narrative that shapes Byzantine history, sites—whether urban or rural—are often used to explain and illustrate imperial trends. However, when we remove that overarching narrative, the sites in Anatolia provide the potential to view them as singular examples of local and regional identity. In this article, we have separated out four types of data: fortifications, coins, faunal material, and archaeobotanical evidence to illustrate how a close examination of the data provides new ways of understanding regional identity. In doing so, we posit that the Byzantine empire needs to be seen as a collection of local identities working alongside one another, but always expressing individual needs and resources

Early lives: The late chalcolithic and early bronze age at Çadır höyük

Çadır Höyük, located in the Yozgat Province of the north-central Anatolian plateau, was continuously occupied from the late sixth millennium BCE until at least the thirteenth century CE. This article focuses on the fourth millennium BCE during which the Uruk System in southern Mesopotamia emerged, flourished and then retracted, and the Kura-Araxes culture from Transcaucasia ventured into Anatolia and the Levant. A close investigation of the Çadır settlement reveals a population that embraced the opportunities afforded it through the expanded trade and intercultural connections available during the millennium; the community transitioned into new socioeconomic patterns accompanied by changes in socioreligious and possibly sociopolitical behaviors. The disappearance of such opportunities at the end of the fourth millennium, rather than decimating a village that had come to rely on them, revealed the resilience of the community as it once again reoriented its focus to more local endeavors

Anatolian empires: Local experiences from hittites to phrygians at Çadır Höyük

Çadır Höyük provides rich evidence for the endurance and transformation of specific cultural features and phenomena at a rural center on the Anatolian plateau as it experienced the waxing and waning of control by imperial political powers of the Bronze and Iron Ages. Especially evident during those periods of imperial power is the construction and maintenance of public architecture; certain economic activities also shift in their importance at those times. Simultaneously, continuity in economic and social organization is also a feature stretching across times of imperial control and its loss. Examination of the archaeological evidence from Çadır Höyük suggests that nothing is as continuous, nor as discontinuous, as it might seem

Stability and change at Çadlr Höyük in central Anatolia: A case of Late Chalcolithic globalisation?

Scholars have recently investigated the efficacy of applying globalisation models to ancient cultures such as the fourth-millennium BC Mesopotamian Uruk system. Embedded within globalisation models is the 'complex connectivity' that brings disparate regions together into a singular world. In the fourth millennium BC, the site of Çadlr Höyük on the north-central Anatolian plateau experienced dramatic changes in its material culture and architectural assemblages, which in turn reflect new socio-economic, sociopolitical and ritual patterns at this rural agro-pastoral settlement. This study examines the complex connectivities of the ancient Uruk system, encompassing settlements in more consistent contact with the Uruk system such as Arslantepe in southeastern Anatolia, and how these may have fostered exchange networks that reached far beyond the Uruk 'global world' and onto the Anatolian plateau

PainDroid: An android-based virtual reality application for pain assessment

Earlier studies in the field of pain research suggest that little efficient intervention currently exists in response to the exponential increase in the prevalence of pain. In this paper, we present an Android application (PainDroid) with multimodal functionality that could be enhanced with Virtual Reality (VR) technology, which has been designed for the purpose of improving the assessment of this notoriously difficult medical concern. Pain- Droid has been evaluated for its usability and acceptability with a pilot group of potential users and clinicians, with initial results suggesting that it can be an effective and usable tool for improving the assessment of pain. Participant experiences indicated that the application was easy to use and the potential of the application was similarly appreciated by the clinicians involved in the evaluation. Our findings may be of considerable interest to healthcare providers, policy makers, and other parties that might be actively involved in the area of pain and VR research

The course of mental health problems in children presenting with abdominal pain in general practice

Objective. To investigate the course of mental health problems in children presenting to general practice with abdominal pain and to evaluate the extent to which abdominal pain characteristics during follow-up predict the presence of mental health problems at 12 months' follow-up. Design. A prospective cohort study with one-year follow-up. Setting. 53 general practices in the Netherlands, between May 2004 and March 2006. Subjects. 281 children aged 4-17 years. Main outcome measures. The presence of a depressive problem, an anxiety problem, and multiple non-specific somatic symptoms at follow-up and odds ratios of duration, frequency, and severity of abdominal pain with these mental health problems at follow-up. Results. A depressive problem persisted in 24/74 children (32.9%; 95% CI 22.3-44.9%), an anxiety problem in 13/43 (30.2%; 95% CI 17.2-46.1%) and the presence of multiple non-specific somatic symptoms in 75/170 children (44.1%; 95% CI 36.7-51.6%). None of the abdominal pain characteristics predicted a depressive or an anxiety problem at 12 months' follow-up. More moments of moderate to severe abdominal pain predicted the presence of multiple nonspecific somatic symptoms at follow-up. Conclusions. In one-third of the children presenting to general practice for abdominal pain, anxiety and depressive problems persist during one year of follow-up. Characteristics of the abdominal pain during the follow-up period do not predict anxiety or depressive problems after one-year follow-up. We recommend following over time children seen in primary care with abdominal pain

When did the chicken cross the road: archaeological and molecular evidence for ancient chickens in Central Asia

The origins and dispersal of the chicken across the ancient world remains one of the most enigmatic questions regarding Eurasian domesticated animals1,2. The lack of agreement regarding the timing and center of origin is due, in large part, to issues with morphological identifications, a lack of direct dating, and poor preservation of thin bird bones. Historical sources attest to the prominence of chickens in southern Europe and southwest Asia by the last centuries BC3. Likewise, art historical depictions of chickens and anthropomorphic rooster-human chimeras are reoccurring motifs in Central Asian prehistoric and historic traditions4-6. However, when this ritually and economically significant bird spread along the trans-Eurasian exchange routes has remained a mystery. Here we show that chickens were widely raised by people at villages across southern Central Asia from the third century BC through medieval periods for their eggs and likely also meat. In this study, we present archaeological and molecular evidence for the cultivation of chickens for egg production from 12 different Central Asian archaeological sites spanning a millennium and a half. These eggshells were recovered in high abundance at all of these sites, suggesting that chickens were widely raised by people at villages across southern Central Asia from the third century BC through medieval periods and that they were an important part of the overall diet. Contrary to views that ancient peoples of Central Asia were primarily herding sheep, goat, and cattle, these data show that chicken was also important in the subsistence economy and that it was widely spread along the ancient Silk Road.Introduction - Rapid Dissemination across the Ancient World Results - Archaeological Eggshells - Peptide Mass Fingerprinting Discussion - Evidence for Non-Seasonal Egg Laying - The Rise in Symbolic and Economic Prominence of the Chicken in Central Asia Conclusion
