Increased temperature sensitivity of net DOC production from ombrotrophic peat due to water table draw-down.

The production and release of dissolved organic carbon (DOC) from peat soils is thought to be sensitive to changes in climate, specifically changes in temperature and rainfall. However, little is known about the actual rates of net DOC production in response to temperature and water table draw-down, particularly in comparison to carbon dioxide (CO2) fluxes. To explore these relationships, we carried out a laboratory experiment on intact peat soil cores under controlled temperature and water table conditions to determine the impact and interaction of each of these climatic factors on net DOC production. We found a significant interaction (P < 0.001) between temperature, water table draw-down and net DOC production across the whole soil core (0 to −55 cm depth). This corresponded to an increase in the Q10 (i.e. rise in the rate of net DOC production over a 10 °C range) from 1.84 under high water tables and anaerobic conditions to 3.53 under water table draw-down and aerobic conditions between −10 and − 40 cm depth. However, increases in net DOC production were only seen after water tables recovered to the surface as secondary changes in soil water chemistry driven by sulphur redox reactions decreased DOC solubility, and therefore DOC concentrations, during periods of water table draw-down. Furthermore, net microbial consumption of DOC was also apparent at − 1 cm depth and was an additional cause of declining DOC concentrations during dry periods. Therefore, although increased temperature and decreased rainfall could have a significant effect on net DOC release from peatlands, these climatic effects could be masked by other factors controlling the biological consumption of DOC in addition to soil water chemistry and DOC solubility. These findings highlight both the sensitivity of DOC release from ombrotrophic peat to episodic changes in water table draw-down, and the need to disentangle complex and interacting controls on DOC dynamics to fully understand the impact of environmental change on this system.

Sadness in mothers’ ‘baby-talk’ predicts affective disorder in adolescent offspring

‘Baby-talk’ is common across cultures. It underpins infant vocal preferences, and helps regulate infant engagement. Its longer-term significance is unclear. In a longitudinal study, we found indications of ‘sadness’ in postnatally depressed mothers’ baby-talk statistically mediated effects of maternal depression on offspring adolescent affective disorder.

In the intersection of the angles of a table, there is more truth than in all the tangle of muscles: Futurism as anti-humanist critique

The recent celebrations of the centenary of the publication of the Futurist manifesto led to a renewed discussion of the ideas and artworks of the Italian artists’ group. Jacques Rancière related the Futurist ethos with the modernist project of liberating art from representation. Franco ‘Bifo’ Berardi, in his post-Futurist manifesto, also identified a historical irony at play in the emptying out of Futurism’s promise: a liberated mechanical humanity did indeed materialize, in a global economic system premised on financial servitude to the future via debt. However, these models continue to assess Futurism against an unchallenged humanism, finding it either supporting ideals of freedom and human rights despite itself, or else lacking in these areas. But Futurism is potentially more relevant than ever not in spite of its anti-humanist agenda, precisely because of it. Tom McCarthy annexes not Futurist art but Futurist writing to an emerging object oriented ontology that seeks to challenge the primacy of the human. If Futurism is to be repurposed as a critical concept, it can only do so by countering the humanist myth the liberal subject that underlies the current cultural and political hegemony of neo-liberalism.

“Bad talk” made good: language variety in four Caribbean British children’s poets

This article looks at how four British-based poets born in the Caribbean exploit the rich language repertoire available to them in their work for children and young people. Following initial consideration of questions of definition and terminology, poetry collections by James Berry, John Agard, Grace Nichols and Valerie Bloom are discussed, with a focus on the interplay and creative tension between the different varieties of Caribbean creoles (“Bad Talk”) and standard English evident in their work. Variation both between the four poets’ usage and within each individual poet’s work is considered, and a trend over time towards the inclusion of fewer creole-influenced poems is noted. This and other issues, such as the labelling of the four poets’ work as ‘performance poetry’ and the nature of the poets’ contribution to British children’s literature, are considered in the conclusion.

Let's talk about sex(ism): cross-national perspectives on women partners’ narratives on equality and sexism at work in Germany and the UK

While the accounting academy has contributed in important ways to furthering our understanding of the relative absence of women in top positions in Professional Service Firms, in-depth empirical research that focuses specifically on sexism is rare, especially so from a cross-national perspective. Drawing on sixty interviews with women partners in public accountancy firms in Germany and the United Kingdom, this article examines how women partners talk about sexism and equal opportunities in the accountancy profession and considers how these narratives are patterned cross-nationally. Employing cultural theory, this study explores how elite women discursively relate to sexism and equal opportunities through their career histories and demonstrates the complex interrelation between the context in which these narratives are produced and the past and present positions of the respondents. Interestingly, it was the German respondents who drew on problematic notions of ‘choice’ and responsibility, where it was upon women to make a choice between their careers and home lives, while this decision-making process was not expected from men. This was in contrast to the accounts of the UK participants who, although also unveiling tensions in their talk, were more inclined to acknowledge continuing structural constraints.

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.
