The explosion of Real Time and the structural conditions of temporality in a society of control: durations and urgencies of academic research

In the context of ongoing debates about the distinctive temporalities associated with contemporary regulative regimes, this paper explores the interpretive trajectories initiated in contrasting conceptualisations of the politics of time. This exploration is developed through analysis of interview data from a study of unconscious relations in academic practice. Section one uses one moment of data to contrast phenomenological, Deleuzian and Lacanian theorisations of the relation between time and subjectivity. Section two is an exegesis of Lacan’s paper on Logical Time. This outlines the way temporality is structured in relation to the subject’s guess about the expectations of the Other. Section three uses this to develop an interpretation of three temporalities that constitute the space of contemporary academic subjectivities. The final section considers the intensification of the juxtaposition of these incongruent temporalities, contrasting Lacanian and Deleuzian theorisations of time in the Real/virtual and their implications for both methodological and political strategy

Reflexivity and Fantasy: surprising encounters from interpretation to interruption

This article sets out two psychoanalytically informed conceptions of fantasy as a resource for reflexivity in research. First is the fantasy as a defensive structure that distorts our perception of reality, and the use of the researcher’s affective responses as an interpretive tool. Second is the fantasy as a signifying structure that constitutes the subject’s engagement in reality, foregrounding unconscious symbolic associations. These approaches are traced in the construction and analysis of interview data, exploring (a) a trajectory that interprets fantasy as a defense against difficult emotions, (b) the construction of free associations, and (c) symbolic material that disrupts the interpretation of fantasy as defense

Recontextualising 'Play' in Early Years Pedagogy: Competence, Performance and Excess in Policy and Practice

This paper traces the way discourses within early years policy and practice impose meanings onto the signifier 'play'. Drawing on Bernstein's conceptualisation of recontextualising strategies, we explore how these meanings regulate troubling excesses in children's 'play'. The analysis foregrounds an underlying question about the hold the signifier 'play' maintains within discourses that appear antithetical to traditional understandings of 'play'. © 2012 Copyright 2012 Society for Educational Studies

Psychical contexts of subjectivity and performative practices of remuneration: teaching assistants' narratives of work

A range of sociological work has theorized neoliberal regulative regimes, suggesting the contradictions contained in the enactment of policy and foregrounding the painful effects of these processes on subjectivities produced within performative school cultures. This paper contributes to this body of work by tracing the movement of desire in teaching assistants? subjective relations to workplace practices of remuneration. We do this through an analysis of a series of group- and individual-free associative interviews with teaching assistants working in primary schools. Drawing on a Lacanian account of the way processes of identification channel affect, as desire, through signifying chains within a discursive field, we explore the associative chains of meaning that overdetermine the subjectivities produced within performative practices of remuneration. We suggest that the complex and contradictory chains of signification embodied in the school environment constitute a space where fragile teaching assistant subjectivities reiterate previous relations to an ambiguous Other

Coherently averaged dual-comb spectroscopy with a low-noise and high-power free-running gigahertz dual-comb laser

We present a new type of dual optical frequency comb source capable of scaling applications to high measurement speeds while combining high average power, ultra-low noise operation, and a compact setup. Our approach is based on a diode-pumped solid-state laser cavity which includes an intracavity biprism operated at Brewster angle to generate two spatially-separated modes with highly correlated properties. The 15-cm-long cavity uses an Yb:CALGO crystal and a SESAM as an end mirror to generate more than 3 W average power per comb, below 80 fs pulse duration, a repetition rate of 1.03 GHz, and a continuously tunable repetition rate difference up to 27 kHz. We carefully investigate the coherence properties of the dual-comb by a series of heterodyne measurements, revealing several important features: (1) ultra-low jitter on the uncorrelated part of the timing noise; (2) the radio frequency comb lines of the interferograms are fully resolved in free-running operation; (3) we validate that through a simple measurement of the interferograms we can determine the fluctuations of the phase of all the radio frequency comb lines; (4) this phase information is used in a post-processing routine to perform coherently averaged dual-comb spectroscopy of acetylene (C2H2) over long timescales. Our results represent a powerful and general approach to dual-comb applications by combining low noise and high power operation directly from a highly compact laser oscillator

Mourning and Melancholia

The conceptual distinctions introduced in Freud’s theorization of mourning, melancholia and melancholic identification can be used to open up the meaning of grief within the political field. Freud’s observation of the visceral ambivalence associated with melancholia provides a basis for later theorizations of the fundamental passion or narcissistic wound that underlies both the intransigence and the unpredictability of forces associated with loss. His conceptualization of complex mechanisms of internalization of both lost objects and cultural prohibitions, provides a basis for exploring processes of repudiation of excluded or marginalized identities. His identification of contrasting processes of internalization and externalization helps us to map the contrasting ways political energies are directed in the aftermath of loss. Most crucially, his formulation of unconscious object loss as a way of explaining intensely painful affective processes guides our understanding of relations to loss as a psychical layer embedded within political and economic relations. To explore the use of these ideas in political theory, this chapter examines a series of cases and suggests that it is important to distinguish between epistemology and the empirical exploration of a specific case. Epistemological arguments indicate some of the political risks involved in the representation of loss; but it is important to remain open minded in exploring unconscious relations to a particular instance of loss in the political field

Circulating Small Extracellular Vesicles May Contribute to Vaso-Occlusive Crises in Sickle Cell Disease

We previously found that the plasma of patients with sickle cell disease (SCD) contains large numbers of small extracellular vesicles (EVs) and that the EVs disrupt the integrity of endothelial cell monolayers (especially if obtained during episodes of acute chest syndrome, ACS). The present study was designed to test the generality of this finding to other complications of SCD, specifically to evaluate the possibility that circulating EVs isolated during a vaso-occlusive crises (VOC) also cause damage to the intercellular connections between endothelial cells. Plasma was obtained from nine pediatric subjects at baseline and during VOC episodes. EVs isolated from these samples were added to cultures of microvascular endothelial cells. Immunofluorescence microscopy was employed to assess monolayer integrity and to localize two intercellular junction proteins (VE-cadherin and connexin43). The EVs isolated during VOC caused significantly greater monolayer disruption than those isolated at baseline. The extent of disruption varied between different episodes of VOC or ACS in the same patient. The VOC EVs disrupted the integrity of both junction proteins at appositional membranes. These results suggest that circulating EVs may be involved in modulating endothelial integrity contributing to the pathogenesis of different complications of SCD
