    The Work of Cultural Intermediaries and the Enduring Distance between Production and Consumption

    This article raises some critical questions about cultural intermediaries as both a descriptive label and analytic concept. In doing so, it has two main aims. First, it seeks to provide some clarification, critique and suggestions that will assist in the elaboration of this idea and offer possible lines of enquiry for further research. Second, it is argued that whilst studying the work of cultural intermediaries can provide a number of insights, such an approach provides only a partial account of the practices that continue to proliferate in the space between production and consumption. Indeed, in significant ways, a focus on cultural intermediaries reproduces rather than bridges the distance between production and consumption. The paper focuses on three distinct issues. First, some questions are raised about the presumed special significance of cultural intermediaries within the production/consumption relations of contemporary capitalism. Second, how 'creative' and active cultural intermediaries are within processes of cultural production is discussed. Third, specific strategies of inclusion/exclusion adopted by this occupational grouping are highlighted in order to suggest that access to work providing 'symbolic goods and services' is by no means as fluid or open as is sometimes claimed

    Does registration of serial MRI improve diagnosis of dementia?

    INTRODUCTION: We aimed to assess the value of a second MR scan in the radiological diagnosis of dementia. METHODS: One hundred twenty subjects with clinical follow-up of at least 1 year with two scans were selected from a cognitive disorders clinic. Scans were reviewed as a single first scan (method A), two unregistered scans presented side-by-side (method B) and a registered pair (method C). Scans were presented to two neuroradiologists and a clinician together with approximate scan interval (if applicable) and age. Raters decided on a main and subtype diagnosis. RESULTS: There was no evidence that differences between methods (expressed as relative odds of a correct response) differed between reviewers (p = 0.17 for degenerative condition or not, p = 0.5 for main diagnosis, p = 0.16 for subtype). Accordingly, results were pooled over reviewers. For distinguishing normal/non-progressors from degenerative conditions, the proportions correctly diagnosed were higher with methods B and C than with A (p = 0.001, both tests). The difference between method B and C was not statistically significant (p = 0.18). For main diagnosis, the proportion of correct diagnoses were highest with method C for all three reviewers; however, this was not statistically significant comparing with method A (p = 0.23) or with method B (p = 0.16). For subtype diagnosis, there was some evidence that method C was better than method A (p = 0.01) and B (p = 0.048). CONCLUSIONS: Serial MRI and registration may improve visual diagnosis in dementia

    Melanoma mouse model implicates metabotropic glutamate signaling in melanocytic neoplasia

    To gain insight into melanoma pathogenesis, we characterized an insertional mouse mutant, TG3, that is predisposed to develop multiple melanomas. Physical mapping identified multiple tandem insertions of the transgene into intron 3 of Grm1 (encoding metabotropic glutamate receptor 1) with concomitant deletion of 70 kb of intronic sequence. To assess whether this insertional mutagenesis event results in alteration of transcriptional regulation, we analyzed Grm1 and two flanking genes for aberrant expression in melanomas from TG3 mice. We observed aberrant expression of only Grm1. Although we did not detect its expression in normal mouse melanocytes, Grm1 was ectopically expressed in the melanomas from TG3 mice. To confirm the involvement of Grm1 in melanocytic neoplasia, we created an additional transgenic line with Grm1 expression driven by the dopachrome tautomerase promoter. Similar to the original TG3, the Tg(Grm1)EPv line was susceptible to melanoma. In contrast to human melanoma, these transgenic mice had a generalized hyperproliferation of melanocytes with limited transformation to fully malignant metastasis. We detected expression of GRM1 in a number of human melanoma biopsies and cell lines but not in benign nevi and melanocytes. This study provides compelling evidence for the importance of metabotropic glutamate signaling in melanocytic neoplasia
