The effects of public capital on private sector performance in Turkish regional manufacturing industries1

This article investigates the impact of public capital formation on private manufacturing sector performance in the seven geographical regions of Turkey and in aggregate. A vector autoregression (VAR) model has been employed to estimate long run accumulated elasticities of private sector variables with respect to public capital for the time period 1980–2000. The results show that public capital affects private output positively in aggregate and in all regions apart from the Black Sea and Mediterranean regions. The results also reveal that only in the Marmara region, the impact is positive both on input and output. The public capital crowds in private sector inputs in some regions.     

Nonlinear Structural Performance of a Historical Brick Masonry Inverted Dome

ABSTRACT

Traditional domes are obtained by double curvature shells, which can be rotationally formed by any curved geometrical plane figure rotating about a central vertical axis. They are self-supported and stabilized by the force of gravity acting on their weight to hold them in compression. However, the behavior of inverted domes is different since the dome is downward and masonry inverted domes and their structural behaviors in the literature received limited attention. This article presents a nonlinear finite element analysis of historical brick masonry inverted domes under static and seismic loads. The brick masonry inverted dome in the tomb of scholar Ahmed-El Cezeri, town of Cizre, Turkey, constructed in 1508 is selected as an application. First, a detailed literature review on the masonry domes is given and the selected inverted dome is described briefly. 3D solid and continuum finite element models of the inverted masonry dome are obtained from the surveys. An isotropic Concrete Damage Plasticity (CDP) material model adjusted to masonry structures with the same tensile strength assumed along the parallel and meridian directions of the inverted dome is considered. The nonlinear static analyses and a parametric study by changing the mechanical properties of the brick unit of the inverted masonry dome are performed under gravity loads. The acceleration records of vertical and horizontal components of May 1, 2003 Bingöl earthquake (Mw = 6.4), Turkey, occurred near the region, are chosen for the nonlinear seismic analyses. Nonlinear step by step seismic analyses of the inverted dome are implemented under the vertical and horizontal components of the earthquake, separately. Static modal and seismic responses of the inverted masonry dome are evaluated using mode shapes, minimum and maximum principal strains and stresses, and damage propagations.     

Rain Making Ceremonies in Iran

Pre-Islamic beliefs and practices abound in Iran, albeit with an Islamic veneer, have been entirely islamicized. One kind of such surviving practices is that of rain making ceremonies. In this article, seven major rain-making ceremonies are categorized, described, and interpreted, including some regional variants thereof. Attention is paid to the fact that these ceremonies are not limited to Iran, but are also found in neighboring countries (Iraq, Turkey, India, Central Asia), thus showing that these are all survivors of common ancient religious archetypes.     

Turkey and the European Union: A Review of Turkey’s Readmission Agreement

Our aim in this article is to analyze Turkey’s Readmission Agreement with the EU in light of Turkey’s membership goal. More specifically, our aim is to propose the most rational political decision for concluding this process. Our study addresses three questions: (1) the impact of the Readmission Agreement on Turkey’s accession negotiations; (2) the outcomes of the implementation of the Readmission Agreement for Turkey; and (3) Turkey’s aim of becoming a full member of the EU by concluding the Agreement. By assessing the three potential scenarios of the Readmission Agreement process—minimum, optimum, and maximum benefit—we conclude that, whereas the first scenario does not coincide with our analysis, the other two, especially the third scenario, do coincide with it. Because the optimum benefit scenario does not disrupt the Readmission Agreement process it appears to be the most rational, balanced and beneficial agreement for both Turkey and the EU.     

Using Optical Coherence Tomography to Examine Additives in Chinese Song Jun Glaze

We use optical coherence tomography (OCT) to acquire microstructure images of Chinese Song Jun glaze to reveal the copper and quartz additives used and, in two typical samples, we show that the amount added is considerable. Focusing on these two additives, including the species, amount and granule (particle) size added in the glaze, the objective of the present study is to explore how they functioned in relation to the Jun glaze's visual characteristics, opalescence and sky‐blue colour, attributed to the unique liquid–liquid phase separation that occurs in Jun glaze.     

The Role of Pattern‐Welding in Historical Swords—Mechanical Testing of Materials Used in Their Manufacture

Pattern‐welding is a well‐known technique that was widely employed in the manufacture of swords. While the decorative effect of genuine pattern‐welding (employing phosphoric iron) is indisputable, to date its reinforcing effect is rather unclear. In order to understand this issue better, wrought iron, phosphoric iron, steel and various pattern‐welded samples were prepared and mechanically tested, and the results obtained are discussed in detail. Both the mechanical testing and the long‐term metallographic investigation of medieval swords suggest that pattern‐welding does not have any significant positive effect on the mechanical properties of swords and we should consider it a primarily decorative technique.     

4. TECHNOPOLITICS IN THE ARCHIVE: SOVEREIGNTY,RESEARCH, AND EVERYDAY LIFE

This article explores the place of the archive in the context of land claims research. This essay develops a critical approach to identity technopolitics with the aim of helping historians working with indigenous communities to ask new kinds of questions about the relationships and subject positions opened up by archivization and the myriad other technologies of land claims research. Since researchers first began preparing for the Canadian case, Delgamuukw’ and Gisday'wa v. The Queen, four decades ago, the immense stores of documentary evidence generated for the trial have given ground to numerous new claims and conflicts. Tracing the experiences of one prominent Gitxsan historical researcher who has leveraged his own archive and expertise to build genealogies for hundreds of individuals, I explore the intimate disappointments and impossible obligations that indigenous historians must mediate.     

The dynamics of emerging middle-power influence in regional and global governance: the paradoxical case of Turkey

This article attempts to understand the properties, potentials and limits of middle-power activism in a changing global order. Extensive debate on the rise of emerging powers notwithstanding, the potential contributions of emerging middle powers in regional and global governance, and the imminent challenges they face in their struggle for an upgraded status in the hierarchy of world politics, is an understudied issue. This study aims to fill this gap by offering a broad conceptual framework for middle-power activism and testing it with reference to the Turkish case. In this context, the authors aim to address the following questions: What kind of roles can emerging middle powers play in a post-hegemonic international system? What are the dynamics, properties and limitations of emerging middle-power activism in regional and global governance? Based on an extensive study of the Turkish case, the authors’ central thesis is that emerging middle powers can make important contributions to regional and global governance. Their ultimate impact, however, is not inevitable, but depends on a complementary set of conditions, which are outlined in this study.
