    The poet sings: “resonance” in Paul Valéry’s poietics

    This paper analyses Paul Valéry’s theories relating to his stated goal of poetic production: the attainment of “resonance” and a “singing-state”. My intention is to defend Valéry’s theory as a valid and consistent model of the creative process in poetry. To that end, I will draw support from T. W. Adorno’s claim that Valéry’s manner of reflective journalising in his Notebooks can furnish us with what he calls “aesthetic insight”. The consistency of Valéry’s theory will be supported by comparisons with the inferentialist understanding of semantics. Valéry proves to be a reliable exemplar of what might be called a “practice-led” aesthetics

    Writing as life performed

    In this chapter I explore the interrelatedness of practice, rehearsal, and performance and their applicability in the domain of “life.” These relationships are complicated when, in reference to Adorno’s Minima Moralia, the content of critical-essayistic production (which is analogous to aesthetic production in many ways) is ultimately that of the life of the author. I propose that to a large extent, the categories of practicing, rehearsing, and performing that are derivable from artistic-productive experience can be extended to lived experience. Working and living seriously and critically have significant points of convergence. What I attempt to disrupt is the presupposition of any “natural” hierarchy between these categories, whereby, for example, performance – connoting the tangible accomplishment of goals and the visibility of that accomplishment – takes precedence over the open-ended tasks of practice and rehearsal

    Dwelling and the sacralisation of the air: A note on acousmatic music

    Get PDF
    This paper adapts Martin Heidegger’s philosophy of ‘dwelling’ in order to effect a liaison between acousmatic music and ecological concern. I propose this as an alternative to both the propagandist use of music as a means of protest and to using the science of ecology as a domain that might furnish new compositional means. I advance the interpretation that acousmatic music ‘occupies the air’ in ways that transform the meaning of that dimension. It allows the sky to be sky and the earth, earth. I use the precedent of bell ringing as an example of sonic activity that occupies the air in order to furthe

    Hundreds of variants clustered in genomic loci and biological pathways affect human height

    Most common human traits and diseases have a polygenic pattern of inheritance: DNA sequence variants at many genetic loci influence the phenotype. Genome-wide association (GWA) studies have identified more than 600 variants associated with human traits, but these typically explain small fractions of phenotypic variation, raising questions about the use of further studies. Here, using 183,727 individuals, we show that hundreds of genetic variants, in at least 180 loci, influence adult height, a highly heritable and classic polygenic trait. The large number of loci reveals patterns with important implications for genetic studies of common human diseases and traits. First, the 180 loci are not random, but instead are enriched for genes that are connected in biological pathways (P = 0.016) and that underlie skeletal growth defects (P < 0.001). Second, the likely causal gene is often located near the most strongly associated variant: in 13 of 21 loci containing a known skeletal growth gene, that gene was closest to the associated variant. Third, at least 19 loci have multiple independently associated variants, suggesting that allelic heterogeneity is a frequent feature of polygenic traits, that comprehensive explorations of already-discovered loci should discover additional variants and that an appreciable fraction of associated loci may have been identified. Fourth, associated variants are enriched for likely functional effects on genes, being over-represented among variants that alter amino-acid structure of proteins and expression levels of nearby genes. Our data explain approximately 10% of the phenotypic variation in height, and we estimate that unidentified common variants of similar effect sizes would increase this figure to approximately 16% of phenotypic variation (approximately 20% of heritable variation). Although additional approaches are needed to dissect the genetic architecture of polygenic human traits fully, our findings indicate that GWA studies can identify large numbers of loci that implicate biologically relevant genes and pathways.

    Ecological release in White Sands lizards

    Get PDF
    Ecological opportunity is any change that allows populations to escape selection from competition and predation. After encountering ecological opportunity, populations may experience ecological release: enlarged population size, broadened resource use, and/or increased morphological variation. We identified ecological opportunity and tested for ecological release in three lizard colonists of White Sands, New Mexico (Sceloporus undulatus, Holbrookia maculata, and Aspidoscelis inornata). First, we provide evidence for ecological opportunity by demonstrating reduced species richness and abundance of potential competitors and predators at White Sands relative to nearby dark soils habitats. Second, we characterize ecological release at White Sands by demonstrating density compensation in the three White Sands lizard species and expanded resource use in White Sands S. undulatus. Contrary to predictions from ecological release models, we observed directional trait change but not increased trait variation in S. undulatus. Our results suggest that ecological opportunity and ecological release can be identified in natural populations, especially those that have recently colonized isolated ecosystems

    Parent-of-origin-specific allelic associations among 106 genomic loci for age at menarche.

    Age at menarche is a marker of timing of puberty in females. It varies widely between individuals, is a heritable trait and is associated with risks for obesity, type 2 diabetes, cardiovascular disease, breast cancer and all-cause mortality. Studies of rare human disorders of puberty and animal models point to a complex hypothalamic-pituitary-hormonal regulation, but the mechanisms that determine pubertal timing and underlie its links to disease risk remain unclear. Here, using genome-wide and custom-genotyping arrays in up to 182,416 women of European descent from 57 studies, we found robust evidence (P < 5 × 10(-8)) for 123 signals at 106 genomic loci associated with age at menarche. Many loci were associated with other pubertal traits in both sexes, and there was substantial overlap with genes implicated in body mass index and various diseases, including rare disorders of puberty. Menarche signals were enriched in imprinted regions, with three loci (DLK1-WDR25, MKRN3-MAGEL2 and KCNK9) demonstrating parent-of-origin-specific associations concordant with known parental expression patterns. Pathway analyses implicated nuclear hormone receptors, particularly retinoic acid and γ-aminobutyric acid-B2 receptor signalling, among novel mechanisms that regulate pubertal timing in humans. Our findings suggest a genetic architecture involving at least hundreds of common variants in the coordinated timing of the pubertal transition
