The absence of legal equality and social justice among different ethnic groups plays a major role in making societies heterogeneous. However, during the process of nation building and the making of a new state, these differences among the population should usually give way to the buildup of a national identity that usually overcomes ethnic and religious differences. However, adhering to a single national identity does not necessarily mean neglecting ethnicity and religion, and the challenge becomes in keeping the balance between both identities, the national one that is related to being a citizen and the original one that deals with the citizen's background. Keeping this balance in a way that does not allow any identity to neglect the other is usually the answer to a stable society that lives in harmony among its components. Kuwait is an example of such a heterogeneous society that has divisions across tribal, as well as sectarian, lines. Therefore, it has been a stable political entity because the ruling elite usually take into consideration the need of all social components in this country. The ruling elite try to guarantee that all groups are satisfied and happy, a practice that has led to stability in this country ever since it was established.  相似文献

This article presents a detailed analysis of two wooden coffins from the 1st centuries BC/AD on Bahrain. New C14 dates are published of samples taken from the coffins, and their method of manufacture is reconstructed. The unexpected conservation of wood in a humid environment like Bahrain is explained.  相似文献

Wood species identification and characterization of its weathering processes are crucial steps in the scientific approach of conservation of wooden cultural heritage. Many precious wooden objects of ancient Egypt are largely present in museums, nevertheless relatively little information is available concerning the nature of timber used and on their status of conservation. To address this gap, the wooden species of three relevant archaeological wood objects (statue, box, and coffin) arising from different Egyptian archaeological sites dated from the Old Kingdom (2,686–2,181 BC) to New Kingdom (1,550–1,069 BC) were deeply studied. Five hardwood and softwood species were identified belonging to Tamarix mannifera, T. gennessarensis, Ficus sycomorus, Vachellia nilotica, and Cedrus sp. Such data confirmed the recurrence of Vachellia and Tamarix among the most common timbers found in ancient Egypt. Scanning electron microscope, Fourier transform spectroscopy, and synchrotron x-ray radiation diffraction were conducted to evaluate the archaeological wood deterioration. The formation of microcracks, biological degradation patterns (fungal colonization), or chemical characterization (accumulation of salts on and in-between wooden cells) were detected. SEM micrographs showed the presence of fungal hyphae and conidial spores on the wooden cells. Significant changes in the chemical wood composition and decrease in the crystallinity index were detected.  相似文献

Between 1974 and 1990, over 30 countries in southern Europe, Latin America, some parts of Asia, Eastern Europe, and Africa made transitions to democracy, nearly doubling the number of democratic governments in the world. Samuel Huntington described this global shift as “Democracy's Third Wave” in an article published in 1991, which was later developed in a book titled The Third Wave: Democratization in the Late Twentieth Century. In these two works, he discusses the causes, features, and transition processes of the third wave of democracy and examines its prospects for sustainability and possible expansion in a nondemocratic world. He argues that the first and second democratic waves “were followed not merely by some backsliding but major reverse waves during which most regime changes throughout the world were from democracy to authoritarianism” (Huntington, 1991a). He also addresses the causative factors of this reverse wave in some countries, and he claims that the third wave of democratization that swept the world in the 1970s and 1980s might become a dominant feature of Middle Eastern and North African politics in the 1990s. The delay in this prophecy for two decades motivates us to question whether the Arab Spring is part of Huntington's third wave of democratization or a new fourth wave of democratization, or even a false start to democracy, as described by Larry Diamond ( 2011 ). The purpose of this article is to examine the causes, features, and transition processes of the Arab Spring in Tunisia, Egypt, Libya, and Yemen in correlation with Huntington's theorization on the third wave of democratization which, along with other available literature in the field, will be combined in a theoretical framework that will enable us to discuss the abovementioned elements of the Arab Spring through the lens of the third wave of democratization. Special attention is paid to the question of whether the Arab Spring falls into the framework of Huntington's theory, or whether it can be classified as a new fourth wave of democratization in countries that have unfavorable environments for democracy. The first part of this article highlights the causative factors that eased the emergence of the third wave of democratization in different parts of the world. The second part provides a historical overview of the major events of the Arab Spring in Tunisia, Egypt, Libya, and Yemen, while the third and fourth parts analyze the causes, features, and transition processes of the Arab Spring from Huntington's third wave perspective.  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

This article aims to contribute to an increased understanding of the importance of migration in humanitarian and ‘post‐humanitarian’ contexts, by exploring the interlinkages between protection and displacement. It argues that the strategies by which conflict‐displaced populations protect themselves are largely based on mobility. Yet, humanitarian approaches to displaced populations do not take sufficient account of the mobility needs of those they assist. Furthermore, the actual location at which aid is provided is affected by funding realities and donor priorities. This article discusses the case of protracted displacement realities of Somali refugees and internally displaced people in Kenya, Somaliland and south‐central Somalia. Based on in‐depth semi‐structured interviews and focus group discussions with humanitarian aid workers and displaced people, the article offers an analysis of the recent ‘stabilization discourse’ that fuels programming directed at the return of displaced Somalis. The authors argue that humanitarian protection is compromised by immobile aid practices and by humanitarian programmes that are guided by states’ interest in refugee return.  相似文献

This article attempts to answer the puzzle of why, amongst undemocratic states, some regimes are more authoritarian than others. The author contends that differing party structures result in different authoritarian outcomes. A ruling, competitive authoritarian regime that has a party structure akin to a cadre party, or where there is little or no intra-party democracy, is more likely to be more authoritarian than a party which has intra-party democracy. The lack or absence of intra-party democracy ensures that elites remain cohesive and that there are lesser opportunities for the opposition to take advantage of divisions in the party, whereas in a party with intra-party democracy, there is a greater possibility of elite disunity, which could be capitalised on by the opposition, and there is also a greater likelihood of a different ideology being propagated by defectors from the party. The cases of the People's Action Party in Singapore and the United Malays National Organization in Malaysia are used to illustrate the author's case.  相似文献
