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

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.     

Spelling of Inflected Verb Morphology in Children with Spelling Deficits

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.     

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

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.     

Research,Teaching and Scholarship in an Expanding Higher Education System 1

It is argued that, basically, academics engage in three activities: teaching, research and scholarship, and that the activity of scholarship must be recognised and separately funded. The concept of scholarship is derived from its historical roots, according to which it supports both teaching and research, but is extended to support all activities in which academics engage. This makes it possible to develop an expanding system of higher education in which all academic activities are appropriately recognised and rewarded and which can operate with significantly lower unit costs than has been the case in the past. However, the need to provide funding for scholarship puts a lower bound to acceptable unit costs.     

Exploring connections between information retrieval systems and information literacy standards

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.

Applying a Software Development Product Cycle to Library Technology Adoption and Development

Product cycles have long been used in software development, but libraries can also benefit from a structured product life cycle to help manage technology development and acquisition. This article outlines a proposed product cycle for library technology management with information on implementing each step of the cycle. It will also include information for librarians assessing the success of structured technology management.
