Anna Magdalena as Bach's Copyist

Among the wives of eighteenth-century composers, no one is perhaps more favourably and affectionately described than Bach's second wife, Anna Magdalena (1701-1760). She has been commonly pictured as her husband's trusted assistant, copying his works in handwriting which closely resembled her husband's beautiful calligraphy. No one appreciates her contributions more than today's musicologists, for her copies are usually 'neat and accurate', and are often among the most important primary sources when Bach's autographs do not survive. Occasionally, however, it is difficult to accommodate this patronising view of her role and its significance. It is well known, for instance, that her copy of Bach's Cello Suites (BWV 1007-1012) contains an unusually large number of inaccuracies and copying errors. One must ask how many of these blunders should be ascribed to her. How would a 'neat and accurate' copyist produce such an error-ridden manuscript if she had made it from a fair copy? In this paper, I shall first discuss Anna's copies of Bach's works, and see if any particular patterns or tendencies in her copying activities emerge when these are placed in this broader chronological context. In an attempt to evaluate her performance as a copyist, I shall look at typical situations in which she worked, while at the same time seeking to discover what additional values her copies may bring to our studies of Bach's life and works.

'What say you to [this] book? Is it yours?'::Oral and Collaborative Narrative Trajectories in the Mediated Writings of Anna Trapnel

This article argues that, when a printed page is initially orally generated and then transcribed, either at the time or on a subsequent occasion by a listener or an interlocutor, there are important critical implications for the “I” of the account. It takes as a case study Anna Trapnel's first published works. Appearing within a few weeks of each other in 1654, The Cry of a Stone and Strange and Wonderful News are both mediated texts, large parts of which depend on the agency of a relater. The article begins by examining the textual traces of the relater, arguing for the centrality of his role and other agencies in the shaping of the works which bear Trapnel's name. Situating itself in relation to a current orientation in feminist autobiographical theory that places emphasis on the external requirement to narrate one's life, rather than on the spontaneous production of autobiography by an inner self, the article emphasizes notions of coaxing, witnessing and intersubjectivity to point up an appreciation of women's life writing as a species of cultural production in which various historical actors—male and female—participate. This dialogic process, which persists into the afterlife of transcription, owes part of its genesis to the political vagaries of 1654 and precipitates two contrasting—but equally “authentic”—versions of Trapnel's life and self. Mapping this movement, discussion concentrates on the ways in which a critical confrontation with women's oral narrative is as much an activity of disentangling as it is of reconstructing, an activity which is revealing of the extent to which a spectrum of social and cultural networks participates in and facilitates the female writing act.

Contemporary Radio Art and Spatial Politics: The Critical Radio Utopias of Anna Friz

The article explores the work of the Canadian sound artist Anna Friz over the last decade. Her work deals explicitly with issues of technology and the relative absence of women's voices on radio. Exploring her work as a composer, installation artist, instrumentalist, performance artist and storyteller, and contextualising these practices within feminist critiques and radio conventions, the article explores Friz's ‘self-reflexive radio’. Ideas of ‘supermodernity’, ‘displacement’ and ‘critical utopia’ are deployed to discuss specific pieces of Friz's work in relation to identity and space. The article argues that Friz reconfigures the radio as a site of resistance to dominant constructions of contemporary globalised space and cultures, the politics of informational capitalism and the uneven flows that these cultures and politics engender.

Common variants at the MHC locus and at chromosome 16q24.1 predispose to Barrett's esophagus

Barrett's esophagus is an increasingly common disease that is strongly associated with reflux of stomach acid and usually a hiatus hernia, and it strongly predisposes to esophageal adenocarcinoma (EAC), a tumor with a very poor prognosis. We report the first genome-wide association study on Barrett's esophagus, comprising 1,852 UK cases and 5,172 UK controls in the discovery stage and 5,986 cases and 12,825 controls in the replication stage. Variants at two loci were associated with disease risk: chromosome 6p21, rs9257809 (P(combined) = 4.09 × 10(-9); odds ratio (OR) = 1.21, 95% confidence interval (CI) =1.13-1.28), within the major histocompatibility complex locus, and chromosome 16q24, rs9936833 (P(combined) = 2.74 × 10(-10); OR = 1.14, 95% CI = 1.10-1.19), for which the closest protein-coding gene is FOXF1, which is implicated in esophageal development and structure. We found evidence that many common variants of small effect contribute to genetic susceptibility to Barrett's esophagus and that SNP alleles predisposing to obesity also increase risk for Barrett's esophagus.

Molecular diagnosis of the myeloproliferative neoplasms: UK guidelines for the detection of JAK2 V617F and other relevant mutations

Molecular genetic assays for the detection of the JAK2 V617F (c.1849G>T) and other pathogenetic mutations within JAK2 exon 12 and MPL exon 10 are part of the routine diagnostic workup for patients presenting with erythrocytosis, thrombocytosis or otherwise suspected to have a myeloproliferative neoplasm. A wide choice of techniques are available for the detection of these mutations, leading to potential difficulties for clinical laboratories in deciding upon the most appropriate assay, which can lead to problems with inter-laboratory standardization. Here, we discuss the most important issues for a clinical diagnostic laboratory in choosing a technique, particularly for detection of the JAK2 V617F mutation at diagnosis. The JAK2 V617F detection assay should be both specific and sensitive enough to detect a mutant allele burden as low as 13%. Indeed, the use of sensitive assays increases the detection rate of the JAK2 V617F mutation within myeloproliferative neoplasms. Given their diagnostic relevance, it is also beneficial and relatively straightforward to screen JAK2 V617F negative patients for JAK2 exon 12 mutations (in the case of erythrocytosis) or MPL exon 10 mutations (thrombocytosis or myelofibrosis) using appropriate assays. Molecular results should be considered in the context of clinical findings and other haematological or laboratory results.

JAK2V617F homozygosity arises commonly and recurrently in PV and ET, but PV is characterized by expansion of a dominant homozygous subclone

Subclones homozygous for JAK2V617F are more common in polycythemia vera (PV) than essential thrombocythemia (ET), but their prevalence and significance remain unclear. The JAK2 mutation status of 6495 BFU-E, grown in low erythropoietin conditions, was determined in 77 patients with PV or ET. Homozygous-mutant colonies were common in patients with JAK2V617F-positive PV and were surprisingly prevalent in JAK2V617F-positive ET and JAK2 exon 12-mutated PV. Using microsatellite PCR to map loss-of-heterozygosity breakpoints within individual colonies, we demonstrate that recurrent acquisition of JAK2V617F homozygosity occurs frequently in both PV and ET. PV was distinguished from ET by expansion of a dominant homozygous subclone, the selective advantage of which is likely to reflect additional genetic or epigenetic lesions. Our results suggest a model in which development of a dominant JAK2V617F-homzygous subclone drives erythrocytosis in many PV patients, with alternative mechanisms operating in those with small or undetectable homozygous-mutant clones.

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - http://www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.
