Combining finite element and finite volume methods for efficient multiphase flow simulations in highly heterogeneous and structurally complex geologic media

The permeability of the Earth's crust commonly varies over many orders of magnitude. Flow velocity can range over several orders of magnitude in structures of interest that vary in scale from centimeters to kilometers. To accurately and efficiently model multiphase flow in geologic media, we introduce a fully conservative node‐centered finite volume method coupled with a Galerkin finite element method on an unstructured triangular grid with a complementary finite volume subgrid. The effectiveness of this approach is demonstrated by comparison with traditional solution methods and by multiphase flow simulations for heterogeneous permeability fields including complex geometries that produce transport parameters and lengths scales varying over four orders of magnitude.     

Characterization of Iron age pottery from eastern Turkey by laser- induced breakdown spectroscopy (LIBS)

Selected pottery sherds coming from the Ayanis, Dilkaya and Karagündüz excavations in eastern Turkey and dated from the Early to Middle Iron Age were examined as regards their composition by using laser-induced breakdown spectroscopy (LIBS). The objective of the study was first to investigate the potential of the LIBS technique in the compositional analysis of pottery and further to explore correlations in spectral data, by using chemometrics methods that would possibly enable discrimination among different sherds. This work is part of a broader study aiming to examine clay variability both before and during the Urartian State period and to explore possible relationships and differences among pottery objects from fortresses and settlements or settlements and cemeteries on the basis of the clay composition of sherds. Preliminary results demonstrate that by using the LIBS technique it is possible to analyse pottery sherds in qualitative and semi-quantitative ways, providing information on the clay and slip composition. Furthermore, encouraging results have been obtained by carrying out principal component analysis (PCA) on the LIBS spectra, which suggest that in certain cases, it is possible to directly correlate spectral information with the origin of pottery sherds.     

Politics of Social Policy in a Late Industrializing Country: The Case of Turkey

This article approaches social policy as an integral component of a capitalist society and, by drawing on the notion of the double movement introduced by Karl Polanyi, argues that social policy intervention both limits and contributes to market expansion. While this argument could be generally applied to recent social policy changes in the current context of economic globalization, these changes were shaped against different histories of social policy development in early and late industrializing countries. This article examines the increasing importance of social policy in late industrializing countries by focusing on the case of Turkey. It is argued that social policy transformation in Turkey has involved the expansion of social security coverage along with the privatization and marketization of health and pension systems. A new system of labour market regulation has contributed to the commodification of labour while the ‘state-supported familialism’, which forms an important aspect of current trends in the area of social care, has served to integrate women in the prevailing flexible employment relations by simultaneously sustaining their position in the gender division of roles within traditional family relations. The populist strategy of polarization pursued by the ruling government is discussed to show how opposition to these trends toward privatization, marketization and labour commodification has been isolated.

FISHERS OF THE CORDED WARE CULTURE IN THE EASTERN BALTIC

Between 2800 and 2400 cal BC pastoralists from Central Europe migrated into the eastern Baltic paving the way for the Corded Ware Culture (CWC), and a new type of economy, animal husbandry. Traditionally the CWC people were viewed as highly mobile due to the lack of substantial traces of dwellings and material culture at settlement sites; they were reliant on an economy based on animal husbandry as demonstrated by zooarchaeological and stable isotopic evidence. However, this paradigm is beginning to shift. Here, we present new AMS radiocarbon (¹⁴C) measurements, pollen and macrobotanical data from sediment samples and a portable fish screen, as well as technological, molecular and isotopic data obtained from ceramic vessels from three CWC sites in the eastern Baltic. Overall, our results indicate a de-Neolithisation process undergone by some CWC groups, particularly in lacustrine and coastal ecotones, and a shift to hunting, gathering and fishing.     

Determination of Optimum Environmental Conservation: Using Multi-Criteria Decision-Making Techniques

The type and degree of conservation areas in Turkey legally dictate the kind of land uses that can and cannot take place in a conservation area. Thus, the conservation scheme is one of the most important criteria in designing an urban land-use plan. The aim of this study is to analyse the effects of various conservation decisions on land-use allocation holding everything else constant. This study uses a land-allocation mathematical programme formulated by Hanink and Cromley [(1998) Land-use allocation in the absence of complete market values, Journal of Regional Science, 38, pp. 465–480] that integrates the geographical information systems with a generalized assignment problem to determine an optimum level of conservation scheme in Cesme/Izmir, a coastal resort in Turkey. The findings state that the proposed technique is indeed very useful and promising to answer diversified practical issues on a more rational basis.     

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.     

Krivopete: Wild Women with Backward-facing Feet in Slovenian Folk Narrative Tradition

An overview of archival material, publications, and contemporary fieldwork outlines the characteristics, constants, and variables of krivopete, as well as modern folkloric transformations of the belief in these beings.     

Coming to terms with a difficult past: the trauma of the assassination of Hrant Dink and its repercussions on Turkish national identity

This paper takes as its subject the question of why some nations are less willing to acknowledge past atrocities. To answer that question, it focuses on the assassination of Hrant Dink – a Turkish‐Armenian journalist – and its repercussions on Turkish national identity. Scrutinising newspaper articles written before and after the assassination (2004–2007), it casts a detailed glance at the struggle between two carrier groups – pro‐ and anti‐acknowledgement groups – and argues that the assassination increased the likelihood of the acknowledgement of the mass killing of Armenians in 1915 by creating a cultural trauma informed by collective guilt. However, the relief generated by the funeral, combined with the strength of the master commemorative narrative regarding the mass killings, decreased that likelihood, and despite the huge public reaction created by the assassination there was no attempt at acknowledgement. As such, the paper contributes to our understanding of the trauma of perpetrators and claims that, in addition to other factors listed by earlier studies, cultural trauma is a necessary but not a sufficient condition for coming to terms with difficult pasts.     

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.
