ABSTRACT

This article offers a textual analysis and semiotic reading of the Rich Kids of Tehran's (RKOT’s) Instagram page. Contributing to scholarship on Iranian youth media practices, this article interrogates how the RKOT navigate urban and rural space to engage in everyday processes of resistance against global and local systemic oppression. Grounding their visual representations on Instagram in historical and cultural context, the author questions how and when quotidian actions are transformed into political transgressions when posted on social media. This article emphasizes the RKOT's agency in shaping their brand by analyzing representations of gender performance, intertextuality, and national identity on Instagram.  相似文献

冷战格局下的美国与伊朗特殊关系(1945—1978)   总被引:1,自引:0,他引:1  
在冷战格局下,从二战结束到伊朗发生革命,美国和伊朗逐渐形成了“特殊关系”。这种特殊关系是依靠双方的武器和石油交易来维系和加强的。美国希望利用这层关系推动伊朗的政治、经济改革以维护伊朗的政治稳定,确保美国在波斯湾和全球的利益。但伊朗国王认为美国需要伊朗及其丰厚的石油作为遏制苏联的工具,不会向他施加太大压力,因此没有完全听命于美国。由此产生对美国、伊朗以及两国之间的关系的严重后果。  相似文献

伊朗伊拉克关系研究(1979-1991)   总被引:3,自引:0,他引:3  
在过去40余年中,伊朗和伊拉克两国关系错综复杂,特别是在伊朗1979年革命以后,由于教派分歧、地区领导权争夺、领土纠纷等因素,两伊冲突呈加剧趋势,并且最终导致爆发两伊战争。海湾战争使两伊关系有所改善,但好景不长。随着冷战结束和地区形势变化,两国的国际处境越发困难,国内问题也层出不穷,因此在经历了革命与战争的磨难后,两国关系渐趋解冻并获绳一些发展,但前景仍不容乐观。  相似文献

Although luster potteries are frequently excavated at archeological sites in Iran, a thorough scientific study of their provenance has not yet been performed. In this work, 43 pieces of Iranian luster pottery (bowl, dish and tile) excavated from Rayy, Kashan, Maragheh, Alamoot, Takht-i-Sulayman and Jiroft were analyzed in order to investigate their origin. The luster shards which belong to Seljuks and Il-Khanids dynasties (12th–13th centuries) were analyzed using proton induced X-ray emission (PIXE) technique. To classify the fragments according to their location and origin, principal component analysis (PCA) and hierarchical cluster analysis (HCA) were applied to the chemical compositions of the body of the shards. We were able to classify the samples into three distinct groups using PIXE.  相似文献

Methods for assaying lysosomal diseases in dried blood samples are very useful today due to its several advantages related to the stability of samples, its transportation, handled and analysis, and its potential use for newborn screening compared to traditional methods in leucocytes samples. For this reason, it is important to validate these assays before being used in routine laboratory. Because of different in biological markers based on ethnicity, we aimed this study to validation a DBS-based fluorometric assay for measurement of α-l-Iduronidase activity for diagnosis of MPS I patients in Iran. DBS samples were collected from 15 MPS I patients and 60 healthy age matched subjects. Diagnostic value, biological variance and α-l-Iduronidase activity were determined. DBS α-l-Iduronidase activity was significantly higher in male subjects than in female group. Using a cut-off level of 1.08 µmol/spot 20 h, sensitivity and specificity were 100 and 98 %. The linearity of test was proved and we showed that within-run and between run precision were 5.6 and 14.66 %. Measurement of α-l-Iduronidase activity in DBS samples is an accurate test for diagnosis of MPS I and because of its rapid shipping and simplicity to keeping, DBS-based enzyme activity could be considered as a useful diagnostic tool in this disease.  相似文献

One of the key features of the Olympic movement is its universalistic appeal, particularly in the sense that it has sought to establish itself as a platform for universal interaction and promotion of universal values. In this paper, we consider the nature, feasibility, and implications of the IOC's promotion of its universalist position in terms of the ethical standards it promotes in relation to universal principles of good governance. A major problem in this respect is the culturally diverse set of constituencies that are incorporated within the Olympic movement, such that the imposition of ‘one size fits all’ policies may be impractical and in many instances undesirable. The authors of this paper therefore argue that although universal agreement is often impractical, general agreement may often be established. The paper therefore presents an approach to balancing centrally promoted principles of good governance with local preferences in terms of the weighting to be given to particular values within the operationalization of good governance. This approach, based on the Analytic Hierarchy Process technique, developed by Thomas Saaty and widely employed in decision-making with regard to evaluating and weighting alternatives, is introduced here in the context of the evaluation of National Sport Federations in Iran. The paper highlights ways in which this technique allows for the expression of local priorities within the general framework of good governance principles in ways which satisfied both global and local priorities. In effect, it is a practical example of what Robertson has termed glocalization. The paper concludes by applying this framework to an evaluation of the National Federation (NF) of Football in Iran as an example of how this technique will be used for the purposes of ranking NFs in terms of performance with respect to elements of good governance which will inform both self-assessment by the NF and the decision-making process for allocation of funds by government to NFs in Iran in the future.  相似文献

采用文献资料、录像观察、数理统计等方法,对参加第27届男篮亚锦赛的中伊男篮攻防数据进行定量、定性分析。结果表明:在场均攻防数据对比中,除了三分球和失误两指标接近外,中国队在各项指标上都要明显低于伊朗队;球队风格方面:伊朗队高强度防守、快节奏攻防转换是整体实力高于中国队的制胜因素;在各位置球员效率方面:中国队在内线方面较伊朗队仍有优势,但其他两位置能力明显不足,使球队整体"木桶效应"突显。  相似文献

Familial hypercholesterolemia (FH) is an autosomal dominant disorder of lipoprotein metabolism caused mainly by mutations in the low-density lipoprotein receptor (LDLR) and apolipoprotein B 100 (APOB) genes. Until now, the molecular basis of FH has been demonstrated in detail in many populations, but there is still very limited Molecular data concerning FH in Iran. The aim of this study was to characterize the LDLR and APOB gene mutations in an Iranian population. A total of 30 non-related Iranian possible FH subjects were studied. Diagnosis of FH was based on the Dutch Lipid Clinic Network diagnostic criteria. All samples were initially tested for three common APOB gene mutations including R3500Q, R3500 W and R3531C using PCR-RFLP assay. Subsequently, promoter and coding region of the LDLR gene was screened by PCR-SSCP analysis and positive results were confirmed by DNA sequencing. Four previously reported polymorphisms 1413G > A, 1725C > T, 1773T > C and 2140 + 5G > A were found in ~17% (5/30) of population studied. Moreover, no variation was found in APOB gene. Our data indicated that LDLR and APOB gene mutations have not contribution to possible FH in Iranian population studied here. However, we examined three common APOB mutations and LDLR in only 30 patients, and to determine the role of these genes in developing FH in Iran, more FH samples and populations needed to be investigated for the mutations of the related genes.  相似文献
