Richard Kirkendall's collection of essays, The Organization of American Historians and the Writing and Teaching of American History, examines the history of the Organization of American Historians (OAH) from its founding to the present, using that history to illuminate how the writing of American history has changed over the last hundred years. The book provides coverage of all the major dimensions of the Mississippi Valley Historical Association's (MVHA) and the OAH's activities, ranging from the work of its scholarly publications, the Mississippi Historical Valley Review and the Journal of American History, to its role in promoting the teaching of American history. Overall, the essays in the volume tell a story of the organization's progress toward greater inclusion and democracy, falling prey to a Whig interpretation of historiography. In doing so, the book is part of a larger tendency in the way that historians have approached historiography, which in turn reflects their ambivalence about their relationship to the historical process. Thus, even as the very enterprise of historiography is premised on the recognition of how historians are themselves the products of the historical process, historians have revealed the limits to that recognition in their approach to the subject. This essay shows how deeply rooted this duality has been in the study of American historiography and illuminates some of its sources by placing Kirkendall's book in the context of how the MVHA and the OAH have treated historiography over the course of the organization's history. 相似文献

The microstructure and chemical composition of blue cakes, found during the archaeological excavation of the Ayanis fortress (Eastern Anatolia, Turkey), have been investigated by means of scanning electron microscopy combined with energy dispersive spectrometry (SEM–EDS), X-ray diffraction (XRD), micro-Raman (μ-Raman) and optical microscopy (OM) techniques. The analysis of the Ayanis cakes has shown the presence of Egyptian blue (i.e. CuCaOSi4O10, cuprorivaite), as the major component, intermixed with minor amount of other phases such as partially reacted quartz grains, an adherent glass phase and copper oxides. Since the finding of Egyptian Blue in Turkey has been never reported so far, great attention has been paid to its characterisation. The micro-chemical and micro-structural investigations of the Ayanis cakes have allowed a further insight into the manufacturing process and into the sources of the starting materials. The results of the characterisation have revealed some significant differences with respect to Egyptian blue cakes found in Egypt and Mesopotamia, as for instance the absence of tin excluded the use of bronze scraps or filings in their preparation differently from those produced in Egypt and Mesopotamia. Furthermore, some peculiarities of Egyptian blue found in Ayanis, as the detection of zinc in the cakes, allow to put forward the hypothesis of a local production considering that a large part of the bronze artefacts found at the Ayanis fortress is characterised by the presence of zinc as minor alloying element. 相似文献

Inelastic displacements of reinforced concrete systems are investigated by employing an energy-based approach. A hysteresis model is developed that accounts for stiffness degradation, strength deterioration and pinching. The model is calibrated by using experimental data from literature. Inelastic displacement ratios are calculated under a specific set of ground motion records with long effective durations. The results reveal the importance of deteriorating behavior under long duration excitations, especially for short and medium period structures. The last part of the study is devoted to the introduction of a simple empirical relationship for estimating the inelastic displacement demands of degrading RC structural systems. 相似文献

This article studies 1923 compulsory population exchange between Greece and Turkey through a case study of its experience in Izmir. It traces the ways the early Republican state engaged in the project of reshaping the population by eliminating the non‐Muslims who were rendered as ‘excesses’ in the spatial and discursive matrices of the nation‐state. Through the experience of the exchange in Izmir, it argues that the process of the accommodation and assimilation of the exchangees played a significant role in shaping the modalities of Turkish nationalism by creating new lines and fissures, further dividing the ‘Muslim brethren’ into ever restrictive constructions of Turkishness. It also underlines that this forced displacement is not just a significant episode in Greek and Turkish histories but that it represents a turning point in the project of nation formation in general. 相似文献

Abstract. This article investigates the dynamics of property prices and their interaction with output growth in a general equilibrium model. Closed form solutions and testable hypotheses are derived from a mildly restricted version of the model. The testable hypotheses are broadly supported empirically. In particular, (1) the volatility of commercial property prices is higher than that of residential property prices, (2) each of the lagged, contemporary, and forward commercial property prices is positively correlated with residential property prices, (3) the contemporaneous covariance between the two property prices is larger than the lagged covariance, and (4) output growth is positively correlated with both property prices. These results are consistent with simulations results that are based on a more general specification of the model. 相似文献

This article argues that the Armenian women living in Istanbul are confined to domestic and communal spaces, and that the roles of symbolizing collective territory and identity, and of cultural reproduction of the community, are mostly associated with women. The data and observations we explore here are based on a field survey of Turkey's Armenian community that was conducted in Istanbul between November 2004 and May 2005. Evaluation of this survey based on both quantitative and qualitative methods allows us to draw some conclusions about the roles of Armenian women in the reproduction of Armenian culture. Women's roles indirectly influence Armenian identity, creating the conditions for its survival. 相似文献

Previous studies on geographical distribution of economic activity in Turkey demonstrate that firms are localized in major metropolitan areas as well as a set of emerging regions. The aim of the paper is to complement the findings of the studies on regional and industrial concentration in Turkey's manufacturing industry by exploring whether regional specialization and industrial concentration patterns changed during the 1980–2000 period. The paper further aims to explore the driving forces of industrial concentration in Turkey's manufacturing industry, particularly during Turkey's economic integration process that started with trade liberalization after 1980 and further developed with the Customs Union in 1996. Regional specialization and industrial concentration are measured by GINI indices Turkey's NUTS-2 regions at the four-digit level for the years between 1980 and 2000. To investigate which variables determine industry concentration, systematic relation between the characteristics of the industry and industrial concentration is tested. Following the method proposed by Paluzie, Pons and Tirado, a panel regression equation is estimated, where the dependent variable is the Gini concentration index and the independent variables are the variables that represent the characteristics of the sectors that follow the predictions of classical trade theory, new trade theory and new economic geography. The major finding of the study is that during 1980–2000, Turkey's regions became more specialized and industry became more concentrated. Increases in the average values of regional specialization and industrial concentration support the prediction developed by Krugman hypothesis that regions become more specialized and industries become more concentrated with economic integration. In exploring the driving forces of industrial concentration, the findings demonstrate that firms tend to cluster in regions where there are economies of scale. 相似文献
