Best of both worlds or refusal to comply? The rich kids of Tehran on Instagram     

Laura P. B. Partain 《Journal of International and Intercultural Communication》2020,13(3):216-237

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

Spelling of Inflected Verb Morphology in Children with Spelling Deficits     

Laura Boynton Hauerwas  Joanne Walker 《Learning disabilities research & practice》2003,18(1):25-35

Children with spelling deficits demonstrate significant difficulty using inflectional morphology in their writing. This study investigated whether phonological deficits account for these pronounced difficulties or if they are more accurately explained by limitations in morphological or orthographic awareness. Twenty–six 11—13–year–old children with spelling deficits, 31 younger spelling–level–matched children, and 31 age–matched children were asked to spell a series of verbs with past tense and progressive markers in dictated sentences and in list form. Performance on spelling tasks was compared to performance on phonological, morphological, and orthographic awareness tasks. Results suggest that children with spelling deficits have significant difficulty including inflections as well as spelling inflections and base words. Difficulty was most pronounced in a sentence context. Ability to spell inflectional forms was related to variation in morphological awareness in children with spelling deficits and to variation in orthographic awareness in spelling–level–matched children.  相似文献

A color image segmentation method as used in the study of ancient monument decay     

Rossella Cossu  Laura Chiappini 《Journal of Cultural Heritage》2004,5(4):385-391

In the cultural heritage area, it is of fundamental importance to characterize and classify the conservation state of the materials constituting ancient monuments, in order to study and monitor their decay. Generally, the decay diagnosis is provided by “naked eye” analysis done by expert scientists “walking around” the artifact and recording the conservation state of each individual element they observe. In this paper, a color image segmentation approach, based on histogram threshold and edge detection techniques is presented, to extract degradation regions, characterized by holes or cavities, from color images of stone-materials. The goal is to provide an aid to the decay diagnosis by segmenting degraded regions from color images, computing quantitative data, such as the area and perimeter of the extracted zones, and processing qualitative information, such as various levels of depth detected into the same zones. Since color is a powerful tool in the distinction between objects, a segmentation technique based on color, instead of intensity only, has been used to provide a clearer discrimination between regions. The study case concerns the impressive remains of the Roman Theatre in the city of Aosta (Italy). In particular, we have processed and analyzed some color images of the theatre puddingstones, acquired by a camera.  相似文献

根据中医内科辩证和因时制宜原则 ,对校田径代表队在夏季比赛期间服用活血皇浆前后进行血液动力流变学和血液有形成分参数的比较观察结果表明 ,运动员服液后在脉率 (PR)、每搏量 (SV)、心输出量 (CO)、左心有效泵力 (VPE)和左心能量有效利用率 (EWK )改善的同时 ,出现心肌耗氧量 (HOV)、心肌耗氧指数 (HOI)、心肌血液需要量 (CMBN)、心肌血液灌注量(CMBV)和总周阻 (TPR)、标准周阻 (SPR)、收缩压 (SP)舒张压 (DP)等参数下降 ,呈现机能和能量节省化 ,而血液状态则表现为血容量 (BV)增多 ,全血粘度 (η)和还原血粘度 (ηr)下降 ,切变应力增高 ,血流速度加快 ,有利于维持微循环正常功能。血液有形成分的改变提示 ,血红蛋白 (Hb)红细胞比积 (HCT)和血小板 (PL T)有增高趋势 ;平均红细胞血红蛋白浓度 (MCHC)下降 ,则有可能与 BV相对增多 ,红细胞 (RBC)体积增大有关  相似文献   

Exploring connections between information retrieval systems and information literacy standards     

Laura Saunders 《Library & information science research》2008

Information literacy involves the location and access of information through retrieval systems, and many information retrieval systems are designed with specific capabilities to support these very skills. In some cases, system enhancements go beyond simple support and alleviate some of the searcher's responsibilities by performing certain tasks for them. By comparing information retrieval functions to the Association of College and Research Libraries' information literacy standards, this article investigates the extent of support that these enhanced systems can offer, and gives librarians greater insight into how these design enhancements could have an impact on information literacy instruction.  相似文献   

Another Look at What Moves Public Opinion: Media Agenda Setting and Polls in the 2000 U.S. Election     

Son  Young Jun; Weaver  David H. 《Int. Journal of Public Opinion Research》2006,18(2):174-197

This study examined two levels of media agenda effects on aggregatepublic opinion from different news sources. The effects wereinvestigated immediately and cumulatively. Content analysisdata from the 2000 U.S. presidential election coverage by fournational news organizations were related to the Gallup pre-electionpoll standings of each candidate. Regression analyses foundthat both the salience of a candidate and the salience of theattributes of a candidate cumulatively, but not immediately,influenced his standing in the polls. An analysis of news sourcessupported the finding that the two levels of agenda-settingeffects seemed mostly cumulative rather than immediate. Newsfrom different sources, however, tended to have effects of differentdegrees and sometimes different directions on candidate pollstandings. Cumulative effects of candidate salience on aggregateopinion change were found for non-partisan and neutral newssources—reporters, poll reporting and public documents—whereasthe effects of candidate attribute salience mostly came frompartisan sources—the candidate himself and members ofthe competing political party. Possible political implicationsof these findings are discussed.  相似文献
