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.     

Using the Information Structure Model to Compare Profile-Based Information Filtering Systems

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher.     

Four Anxieties and a Reassurance: Hare and McLaughlin on being open-minded

In suppport of the idea that education should encourage open-mindedness, Hare and McLaughlin have argued that being open-minded about an issue, in a philosophically well-supported sense of 'open-mindedness', need not prevent one from holding a firm belief on that issue. In this paper I examine the lack of cohesion in this sense of 'open-mindedness', explain why I continue to be anxious about the tensions between open-mindedness and holding firm beliefs and present three further reasons for having reservations about Hare and McLaughlin's proposals.

Continuing Education in a Late-modern or Global Society: Towards a theoretical framework for comparative analysis

Continuing education, those forms of education that occur after initial education, is exposed to the global market forces in a twofold manner which is foreign to traditional education: firstly, it has to relate to the changing structures and demands of the workforce in the global market and, secondly, it is a marketable commodity in itself. This means that there are no simple systems of continuing education that can be compared between nations or even between occupational categories. This paper, therefore, endeavours to provide a taxonomy which might underlie comparative theorising about continuing education.
