This article contributes to academic literature on the project of identity formation in a postcolonial nation‐state. The article argues that a nation‐state emphasising certain aspects of the past for commemorative or celebratory purposes, while suppressing or ignoring the memories of some other event or historical figure, are both parts of the same process. Both these processes, in different ways, seek to give a certain direction to the narrative about the history of the nation and the nation‐state. These aspects of national memory and amnesia have been explained through the prism of national/public holidays while foregrounding the case study of Pakistan. The article argues that although this process of shaping a specific narrative (referred to as commemorative narrative in this article by using Yael Zerubavel's work) is common to every project of identity formation, its peculiarity is more pronounced in a postcolonial state like Pakistan, which has certain cut‐off dates and ruptures but is, simultaneously, eager to emphasise continuities in its trajectory and antiquity in historical tradition. The study of the process of developing a national calendar in case of Pakistan will show that identity formation is a transient process in which various identarian values, political considerations and social processes play an important part. In particular, it requires an attempt on the part of the state to try impose a homogenising historical narrative by envisaging a national calendar, i.e. by announcing a national or public holiday. This helps accord prestige to persons credited as founding fathers or ideologues, ascribe solemnity to days remembering wars and festivity to mark independence or religious occasions. By discussing these themes in detail, this exploratory study of the history of national calendar will lend an alternative lens through which to look into the processes of identity formation in postcolonial nation‐states in general. 相似文献

Fourier transform infrared spectroscopy and imaging coupled to optical microscopy, scanning electron microscopy coupled to energy dispersive x-ray spectroscopy and high-performance liquid chromatography (HPLC) coupled to diode-array detection are used to investigate two samples removed from a painted decoration of a burial kline and a textile fragment, both found in Koru tumulus (fifth century BCE) in Daskyleion. Tyrian purple and kaolinite were identified in both samples, thus suggesting that the aluminosilicate compound had an important role in the applied painting and dyeing processes. The textile fragment is composed of undyed cotton and silk yarns dyed with the molluskan dye. The relative compositions of the molluskan materials used in the two archaeological objects are similar and comparable with the corresponding composition measured for a purple sample originated from Murex trunculus mollusks according to the HPLC results. This result is supported by principal component analysis (PCA) which, furthermore, takes into account the relative compositions of the extracts of the three Mediterranean mollusks, published in previous reports. 相似文献

The unexpected damages in structures during severe earthquakes have been reported frequently so far. In this study, the damage-based inelastic behavior of special moment resisting frame (SMRF) structures designed according to the new versions of general earthquake loading codes (International building code [IBC] 2012 & American Society of Civil Engineers [ASCE] 7-2010) and seismic design references (National Earthquake Hazards Reduction Program [NEHRP] 2009 & Federal Emergency Management Agency [FEMA] P-750) has been investigated. The final results presented based on distinctive shear and flexural failure modes show that a non-uniform distribution of severe damage in structural height occurs during design level seismic excitations. Also it is observed that the shear and flexural damages are more critical in short and tall MRF structures, respectively. 相似文献

It is well known that the soil-structure interaction (SSI) changes the dynamic response of a structure supported on flexible soil. The analysis of optimally controlled SSI systems has certain difficulties due to the nature of the SSI and the optimal control problem. In this paper, a two-step iteration-based numerical algorithm is proposed to handle optimally controlled SSI systems under earthquakes. First, the optimal control forces are obtained by using a fixed-base system. Then, the optimal control forces are converted to the frequency domain by the Fourier transform technique to be used in the equations of the SSI system. The lateral displacement and the rocking of the foundation are obtained from the equations of the SSI system containing the optimal control forces in the frequency domain. The lateral displacement and rocking of the foundation are then converted to the time domain by the inverse Fourier transform technique, and the lateral accelerations and the rocking accelerations of the foundation are obtained by the forward finite difference method. During the second step, the optimal control forces are calculated again by using the lateral acceleration and the rocking acceleration of the foundation along with the earthquake ground motion. Using the method explained above, the optimal control forces obtained in the time domain are used in the equations of the soil-structure system from which the behavior of foundation and structure is obtained. In the final section of the paper, a numerical study is conducted for a controlled structure supported on flexible soil. 相似文献

A Study of Biodeterioration and Chromatic Alterations of Painted and Gilded Mummy Cartonnage at the Saqqara Museum Storeroom,Egypt 下载免费PDF全文
Microbial biofilms have developed on the surfaces and within the painted and gilded layers of mummy cartonnage at the Saqqara museum storeroom in Giza, Egypt. SEM–EDX, XRD and FT–IR–ATR techniques were applied to analyse the coloured and gilded materials, ground layer, textile support and binder used for the cartonnage. Aspergillus niger (24.8%), Penicillium chrysogenum (21.5%) and a novel cartonnage‐biodegrading bacterium, Bacillus sonorensis (23.7%), were the most abundant microbes growing over the cartonnage surface. In addition, Aspergillus tamari (15.4%), A. fumigates (8.1%) and Fusarium solani (6.5%) were identified. The pigments comprised Egyptian blue (cuprorivaite), cinnabar (red), orpiment (yellow) and green pigment made from a mixture of cuprorivaite and orpiment. Gold leaf was used for the gilded layer, calcium carbonate and gypsum comprised the ground layer, gum arabic was the binding medium and the fibre base was a fine linen textile. Microbial colonization tests were performed on aged cartonnage replica samples made from linen and pigments of similar composition to ancient pigments found in the cartonnage. Each sample was inoculated separately with A. niger, P. chrysogenum and B. sonorensis. Yellow orpiment samples were the exception, as no colour change was detected after colonization by the examined micro‐organisms. 相似文献

This article demonstrates how some contemporary scholars, operating from within the traditional Shiʿi establishment, have paved the way for new interpretations of Islam in general and Shiʿism in particular. To do so, the article focuses on three specific themes: the notion of the (im)purity of non-Muslims, rulings on apostasy and precepts related to women's rights. Following a brief explanation of the history of Shiʿism, the article addresses each of three aforementioned themes in turn. In each section, the article explains how the relevant theme was approached by earlier religious scholars, and how it has been treated differently by some contemporary reformist Shiʿi clerics. While not claiming the trends of thought instigated by some contemporary ʿulamāʾ are entirely homogeneous with liberal ideas about human rights, this article provides examples of Shiʿi legal standpoints being reformed to meet the challenges of the contemporary world. 相似文献
