Can shifting to tidal time potentially slow the catastrophic realities of sea-level rise? Sarah Cameron Sunde’s 36.5 / A Durational Performance with the Sea is a site-specific performance during which Sunde stands in a tidal bay for a full cycle as water engulfs her body and then reveals it again. The public participates. What began in 2013 as a poetic impulse has grown into a complex series of nine durational performances involving communities around the world. In this article, durational performance (...) artist and scholar Raegan Truax gleans insight from Indigenous feminist scholars and Indigenous women-led movements to analyse the choreographic and temporal dynamics of 36.5. Co-writing with the artist, and focusing specifically on Sunde’s durational shift to tidal time, Truax proposes a phenomenological undoing: ‘becoming Sea-swallowed’ as essential to the speculative possibility of ‘becoming otherwise’.

The Routledge Companion to Sounding Art presents an overview of the issues, methods, and approaches crucial for the study of sound in artistic practice. Thirty-six essays cover a variety of interdisciplinary approaches to studying sounding art from the fields of musicology, cultural studies, sound design, auditory culture, art history, and philosophy. The companion website hosts sound examples and links to further resources. The collection is organized around six main themes: Sounding Art: The notion of sounding art, its relation to sound (...) studies, and its evolution and possibilities. Acoustic Knowledge and Communication: How we approach, study, and analyze sound and the challenges of writing about sound. Listening and Memory: Listening from different perspectives, from the psychology of listening to embodied and technologically mediated listening. Acoustic Spaces, Identities and Communities: How humans arrange their sonic environments, how this relates to sonic identity, how music contributes to our environment, and the ethical and political implications of sound. Sonic Histories: How studying sounding art can contribute methodologically and epistemologically to historiography. Sound Technologies and Media: The impact of sonic technologies on contemporary culture, electroacoustic innovation, and how the way we make and access music has changed. With contributions from leading scholars and cutting-edge researchers, The Routledge Companion to Sounding Art is an essential resource for anyone studying the intersection of sound and art.

Woods et al. (2015) claim that secular Simple Reaction Time (SRT) slowing (Woodley et al. 2013), disappears once modern studies are corrected for software and hardware lag, and once Galton’s data are corrected for fastest-response selection. Here, this is challenged with a reanalysis of the secular slowing of SRT in the UK amongst large (N>500), population-representative age-matched (≊18-30 years) studies. Starting with Galton’s sample, this is assigned the simulated value estimated by Dodonova and Dodonov (2013, who like Woods et al. (...) were critical of secular SRT slowing, owing to measurement issues) on the basis that he collected the fastest of three trials (207.5ms). The two sexes in Galton’s study are combined (as in Woods et al.), raising the weighted sample mean to 208.5ms. Next is the Wilkinson and Alison (1989) study, which attempted to replicate Galton’s study one century later, collecting SRTs as part of an exhibit in the London Science Museum. An electronic chronoscope recorded SRTs on magnetic tape, and sampled over eight trials with micro-processor-determined variable foreperiods. The mean SRT value for the 1,189 participants aged between 20 and 29 is 245ms. The presence of long and variable foreperiods necessitates a penalty of 10ms (Dodonova & Dodonov, 2013). Another 10ms should be deducted based on key-pressing time (Dodonova & Dodonov, 2013), reducing the mean to 225ms. The studies of Deary and Der (2005) and Der and Deary (2006) are also included. The first utilized the highly representative Scottish Twenty-07 cohort. Dodonova and Dodonov (2013) identified a 53ms lag stemming from liquid crystal stimulus onset delay. This is subtracted from the weighted average of the two sexes (300.8ms), along with another 10ms for key-pressing time. The resultant mean is 237.8ms.Dodonova and Dodonov (2013) cleaned the male data in the Der and Deary (2006) study, collected from the representative UK Health and Lifestyle Survey, by removing cases for which SRT standard deviations exceeded those for choice RT. This reduced the N from 834 to 661, and also reduced the mean from 300ms to 284ms. The estimate was also penalized for LCD onset delay and key-pressing time, reducing the mean to 221ms. When the SRT value for the female sample is penalized equivalently the resulting value is 239ms. In order to simulate the female N for the purposes of taking a weighted average of both sexes, the actual female N is reduced in proportion to the male N (79.3%=881), yielding a weighted mean of 230.9ms for a combined sample-size of 1,472. Table 1 presents the data used in the analysis.Table 1 SRT means, sample sizes and sampling years for four large, age-matched UK samples[Table 1 here]Consistent with Dodonova and Dodonov (2013), N-weighted regression is employed, as the only data on sample variability is sample size. Figure 1 illustrating the secular trend in UK SRT over 100 years.[Figure 1 here] Figure 1. Secular SRT slowing across four large, representative studies from the UK spanning a century. Bubble-size is proportional to sample size. Combined N=6,622. The secular slowing between UK studies is statistically significant (β=0.97; 95% CI=0.969 to 0.971, N=6,622), at –22.8ms a century. Additional evidence for generational SRT slowing comes from Verhaeghen (2014), who suggested that the ratio of longitudinal to cross-sectional age-related slowing might tentatively infer generational changes in processing speed. Verhaeghen reports ratios for two SRT studies (0.91 and 1.15), implying both secular losses and gains. For the study of Deary and Der (2005), the SRT ratios are “censored because they were excessively large” (p. 256). In this study, the ratio of the cross-sectional slowing trend (taking the weighted average of all paired between-cohort differences rescaled in terms of change per decade for males and females), to the weighted average decadal longitudinal slowing trend for both the males and females is 0.73, for an N of 1,926 (cf. Woodley et al., 2014b, for a detailed reanalysis of this dataset). The weighted average of the three SRT ‘Verhaeghen ratios’ is 0.9 (N=4,078) – tentatively consistent with generational declines (i.e. a ratio of <1). In conclusion Woods et al. (2015) have undoubtedly made an important contribution to the debate concerning the role of software and hardware lag in the inflation of contemporary estimates of SRT, however the evidence for generational SRT slowing remains quite compelling.

Argues that affirming the irreducible differences between men and women can lead to more transformative politics than the struggle for abstract equality between the sexes. In The Symbolic Order of the Mother Luisa Muraro identifies the bond between mother and child as ontologically fundamental to the development of culture and politics, and therefore as key to achieving truly emancipatory political change. Both corporeal development and language acquisition, which are the sources of all thinking, begin in this relationship. However, Western civilization (...) has been defined by men, and Muraro recalls the admiration and envy she felt for the great philosophers as she strove to become one herself, as well as the desire for independence that opposed her to her mother. This conflict between philosophy and culture on the one hand and the relationship with the mother on the other constitutes the root of patriarchy’s symbolic disorder, which blocks women’s (and men’s) access to genuine freedom. Muraro appeals to the feminist practice of gratitude to the mother and the recognition of her authority as a model of unconditional nurture and support that must be restored. This, she argues, is the symbolic order of the mother that must overcome the disorder of patriarchy. The mediating power of the mother tongue constitutes a symbolic order that comes before all others, for both women and men.

Murphy is Houston-Truax-Wentz Professor and Regents Professor of English at Oklahoma State University. (shrink)
