Making the tacit explicit: children's strategies for classroom writing

A key highlight of this study is generating evidence of children ‘making aware the unaware’, making tacit knowledge explicit. The research explores the levels of awareness in thinking used by eight 7–8 year-old children when engaged in school-based genre writing tasks. The focus is on analysing children’s awareness of their thought processes, using a framework originally devised by Swartz and Perkins (1989), in order to investigate ways in which children can transform their tacit knowledge to explicit within the writing process. Classroom ‘think aloud’ protocols are used to help children ‘manage their knowledge transfer’, to speak the unspoken. In their framework Swartz and Perkins distinguish between four levels of thought that they view as hierarchical and ‘increasingly metacognitive.’ However, there is little evidence in this study to show that levels of awareness in thinking are increasingly progressive and observations made during the study suggest that young writers move in and out of the suggested levels of thinking during different elements of a writing task. The reasons for this may depend on a number of factors which are noted in this paper. Evidence does suggest children in this age group are consciously aware of their own and others’ thought processes both with and without adult prompting. By using collaborative talk, their awareness of these thought processes is highlighted enabling the co-construction and integration of new ideas into their existing knowledge base.

Girls talk: authorship and authenticity in the reception of Lena Dunham's Girls

By examining the discourse around Lena Dunham's HBO comedy Girls (2012– present), this article argues that the programme served as a space to think through female authorship, televisual representations and cultural tensions surrounding young womanhood. Central to this discourse was the narrative asserting Girls' and Dunham's 'authenticity', originality and universality, which sought to legitimate her gendered authorship and interest in the comedy of female intimacy within HBO' s masculine prestige channel identity. Charting three cycles of discourse surrounding the programme's debut, this article explores the paratextual framing by promotional concerns, television critics and women' s websites. It highlights how journalists and critics furthered HBO's paratextual framing of Dunham, which was later countered by the networked spaces of niche online media, which used the programme as a space to productively work through industrial and cultural tensions; particularly those surrounding female comic authorship, autobiography and intersectionality.

How distinctive is philosophers’ intuition talk?

The word “intuition” is one frequently used in philosophy. It is often assumed that the way in which philosophers use the word, and others like it, is very distinctive. This claim has been subjected to little empirical scrutiny, however. This article presents the first steps in a qualitative analysis of the use of intuition talk in the academy. It presents the findings of two preliminary empirical studies. The first study examines the use of intuition talk in spoken academic English. The second examines the use of intuition talk in written academic English. It considers what these studies tell us about the distinctiveness of philosophical language and methods and considers some implications for evaluative and ameliorative methodology.

'You show me yours, I'll show you mine': the negotiation of shifts from textual to visual modes in computer-mediated interaction among gay men

This article explores the way users of an online gay chat room negotiate the exchange of photographs and the conduct of video conferencing sessions and how this negotiation changes the way participants manage their interactions and claim and impute social identities. Different modes of communication provide users with different resources for the control of information, affecting not just what users are able to reveal, but also what they are able to conceal. Thus, the shift from a purely textual mode for interacting to one involving visual images fundamentally changes the kinds of identities and relationships available to users. At the same time, the strategies users employ to negotiate these shifts of mode can alter the resources available in different modes. The kinds of social actions made possible through different modes, it is argued, are not just a matter of the modes themselves but also of how modes are introduced into the ongoing flow of interaction.

Transcriptomics and proteomics show that selenium affects inflammation, ctoskeleton, and cancer pathways in human rectal biopsies

Epidemiologic studies highlight the potential role of dietary selenium (Se) in colorectal cancer prevention. Our goal was to elucidate whether expression of factors crucial for colorectal homoeostasis is affected by physiologic differences in Se status. Using transcriptomics and proteomics followed by pathway analysis, we identified pathways affected by Se status in rectal biopsies from 22 healthy adults, including 11 controls with optimal status (mean plasma Se = 1.43 μM) and 11 subjects with suboptimal status (mean plasma Se = 0.86 μM). We observed that 254 genes and 26 proteins implicated in cancer (80%), immune function and inflammatory response (40%), cell growth and proliferation (70%), cellular movement, and cell death (50%) were differentially expressed between the 2 groups. Expression of 69 genes, including selenoproteins W1 and K, which are genes involved in cytoskeleton remodelling and transcription factor NFκB signaling, correlated significantly with Se status. Integrating proteomics and transcriptomics datasets revealed reduced inflammatory and immune responses and cytoskeleton remodelling in the suboptimal Se status group. This is the first study combining omics technologies to describe the impact of differences in Se status on colorectal expression patterns, revealing that suboptimal Se status could alter inflammatory signaling and cytoskeleton in human rectal mucosa and so influence cancer risk.
