The Coupled Influence of Relative Density,CSR, Plasticity and Content of Fines on Cyclic Liquefaction Resistance of Sands

In this study, stress-controlled cyclic simple shear tests were performed on sand specimens with up to 10% silt or clay contents, and coupled effects of plasticity, fines content (FC), relative density (D_R) and CSR (cyclic stress ratio) were investigated. The results demonstrated that for sands with low fines content, reasonable trends were obtained when the packing index control parameter was selected as D_R. Also, clean sand specimens demonstrated highest liquefaction strength compared with that of sands with fines up to 10% FC. The effect of fines’ plasticity became apparent as the FC increases and CSR reduces in relatively denser specimens.     

Turkish nationalism and the evolutionary idea (1923–1938)

This paper sheds light on the role of evolutionary ideas in the making of Turkish nationalism during the Kemalist era (1923–1938). By so doing, it aims to challenge some of the dominant historiographical viewpoints as to the nature of Turkish nationalism. One is related to the Kemalist elites' predisposition towards the so‐called “scientism” seen as one of the bases for nationalism. We intend to turn upside–down the relation between the Kemalists' use of science and Turkish nationalism. Second, we problematize the “culturalist” origins of Turkish nationalism arguing that the seemingly “culturalist” reflections of the time were, indeed, materialist formulations based on the science of the times. We discuss in this respect the Kemalist elites' use of evolutionary ideas. By synthesizing the ways in which these elites employed evolutionary ideas in the fields of history, language, geography, anthropology, biology, eugenics, and pedagogy, we aim to understand the specific nature of Turkish nationalism before 1945. This secular nationalism conceived culture as having materialist bases and differed fundamentally from the culturalist varieties of Turkish nationalism coloured by Islam in the post‐1945 era. Furthermore, the paper empirically enriches the complex and entangled story of evolutionary ideas in the early Turkish Republic.     

Arendt’s Promise to Civil Society: Bridging the Social and the Political

In Arendt’s political theory the concept of civil society is often read as an extension of her concept of the social and is therefore dismissed as irrelevant to her political vision. This view leaves Arendtian theory in an exclusivist position with regard to contemporary political contexts and experiences. My aim in this essay is to address this problem by discussing the relationship of Arendtian theory and the concept of civil society in the context of contemporary political experience. This calls for not only a particular reading of the social in Arendt but, more importantly, for a joint reading of Arendt’s concept of the council state and civil society. Here, civil society is defined as the associations institutionalized by the voluntary engagement of active citizens, which definition, I argue, is compatible with Arendt’s concept of politics as action, plurality, and participation.     

Rethinking the Ottoman Imitation of Persian Poetry

This article revisits the common discourse that Ottoman poetry is a derivative imitation of Persian poetry. I begin by surveying and discussing the discourse of imitation that has pervaded approaches to Ottoman poetry in particular and Ottoman literature in general. Then I turn to explore how Ottoman poets engaged with Persian poetry by focusing on a lyric poem composed by the Ottoman sultan Süleyman the Magnificent (1494?1566) in imitation of the Persian master poet Hafiz of Shiraz (ca. 1315?90). In light of intertextual analysis, I illustrate and discuss the intricate ways in which Süleyman models himself on Hafiz in crafting his poem. I conclude with the idea that a closer analytical look at Ottoman poets’ intertextual dialogue with Persian poetry can offer better insights into the Ottoman reception of Persian poetic models as well as into the meaning and workings of imitation in the Ottoman literary context.     

Thermographic Survey at Hagia Sophia: Main Arches,Pendentives and Tympana

Hagia Sophia is one of the oldest and most complex existing monuments. Many unanswered questions are still open on the historical and constructive evolution of this monument. The boundaries between the different construction phases and the details of the masonry and materials used in the various phases are still not defined with precision.

The thermographic survey, carried out inside the monument, made ??it possible to answer some of these questions by specifying the exact location of the past interventions and the variability of the materials employed allowing a better understanding of the constructive history of the monument. The technique was applied at a great distance and in normal environmental conditions, taking advantage of the high thermal sensitivity of the instrumentation. The results achieved confirm the validity of the technique in the study of ancient buildings.     

Turkish–Dutch mosques and the formation of moral subjects

This article explores how mosque spaces become everyday sites of ethno-religious subjectivation for immigrants and citizens originating from Turkey in the Netherlands. I argue that the symbolic and material constructions of mosques as simultaneously moral and moralizing spaces undergird the production of ethno-religious subjectivities through mosque-centered everyday practices. The articulation of Muslimness to Turkishness at mosques in culturally specific and gendered ways is crucial for the formation of a particular modality of the Turkish–Dutch self as moral subject. The ensuing incorporation of practices and activities that are deemed ‘secular,’ i.e. ‘cultural’ or ‘recreational’ to mosque services engenders a creative tension between the sacred and profane conceptions of mosque space. Mosque administrators and their congregations concur that recreational activities and quotidian accessibility to mosques are essential to the long term survival of Turkish–Dutch alterity, for mosques are spaces where children and youth are exposed to the performances of Turkish-Islamic morality and subjected to collective social control. However, the diversification of mosque services does not always sit comfortably with the meaning and use of mosques as sacred sites proper within a secularized framework. A creative tension between mosques as serene and pure spaces of the sacred and mosques as impure and immoral spaces of the everyday arises, as a result.     

Georadar investigations in the central nave of Hagia Sofia,Istanbul (Turkey)

Within an interdisciplinary project to study Istanbul’s Hagia Sofia, a georadar survey was carried out in the central nave to assess if the deformations of the structure previously observed could be related to a differential behavior of the subsoil caused by architectural remains underneath. This study faces an unusual challenge since it was necessary to study the space beneath the scaffolding placed for the restoration works. The survey of the central nave was successful and allowed the detection of remains of walls that probably formed the basement of a previous 18- by 22-m structure. In addition, another interesting feature was discovered 2 m below the marble mosaic in the southeastern part of the nave. Although it is not possible to define its function, it seems that there could be a close relationship between this 2- by 3-m buried structure and the marble mosaic in the floor surface. Although some structures were identified under the floor of Hagia Sofia, there are no major changes in the topography of the central nave floor.     

Material Politics Facing Post-Truth: Speculation,Infrastructure, and Ecology in Turkey

Despite their imposing material presence, the values and harms stemming from the construction of infrastructural megaprojects remain speculative affairs in Istanbul, Turkey. This article distinguishes two modes of speculation pertaining to megaprojects that present different ethical and political possibilities, namely de-materialising and re-materialising speculation. Contributing to debates about material politics informed by Noortje Marres (Material Participation; Palgrave Macmillan, 2015) and William Connolly (The Fragility of Things; Duke University Press, 2013), our framework of de- and re-materialising speculation avoids isolating material and planetary agency to instead consider how their uncertainties and potentials play a role at the intersection with politico-economic life. Accordingly, we analyse the coalescence of ecological and democratic crises. In Turkey, populism’s anthropocentric construction of “the will of the people” exacerbates ecological collapse. But also, ecological collapse inspires a search for a politics and ethics that acknowledge human–nonhuman ecological entanglements. The contestation between de-and re-materialising speculation underscores possibilities and limitations of ecological politics in contexts of populism and post-truth.
