Trials, Truth-telling and the Performing Body

In this thesis, I examine the role performance plays in the adversarial criminal jury trial. The initial motivation behind this inquiry was the pervasiveness of a metaphor: why is the courtroom so frequently compared to a theatre? Most writings on this topic see the courtroom as bearing what might be termed a cosmetic resemblance to a theatre, making comparisons, for instance, between elements of costume and staging. I pursue a different line of argument. I argue that performance is not simply an embellishment of the trial process but rather a constitutive feature of the criminal jury trial. It is by means of what I call the performance of tradition that the trial acquires its social significance as a (supposedly) timeless bulwark of authority and impartiality. In the first three chapters I show that popular usage of the term ‘theatrical’ (whether it be to describe the practice of a flamboyant lawyer, or a misbehaving defendant) is frequently laden with pejorative connotations and invariably (though usually only implicitly) invokes comparison to a presupposed authentic or natural way of behaviour (‘not-performing’). Drawing on the work of Michel Foucault and Pierre Bourdieu I argue that, whatever legal agents see as appropriate trial conduct (behaviour that is ‘not-performing’), they are misrecognising the performative accomplishments and demands required of both legal agents and laypersons in the trial. This performance constructs and maintains a gap between legal practitioners and laypersons which is essential to maintaining the status of the legal profession, and which continually positions the trial in legal and popular belief. I then look at specific moments of ‘anxiety’ where alterations to traditional procedure provoke debate as to the otherwise unnoticed or unarticulated value of live performance. In Chapter 4, I examine the growth of the private advocacy training industry that frequently positions lawyers as actors. Resistance to the idea of acting demonstrates the tainted status of performance terminology as well as legal agents’ belief that lawyers are acting naturally. I argue instead that lawyers have always been trained in acting: an habituated performance style I term legal naturalism. In Chapter 5, I examine the television broadcasting of trials. Some legal agents argue that broadcasting risks ‘theatricalising’ the trial—causing participants to ‘act up’. However, this overlooks the fact that the court has a long history as a source of popular entertainment. I argue that resistance to broadcasting also stems from a reluctance to remit control of the trial to external producers. Broadcasting invites greater scrutiny into a process that if not always fair, needs to be believed in as fair and has historically been tightly self-regulated by the legal field, through its reliance on live performance’s ‘essential’ quality—its inability to be captured and subsequent disappearance. In Chapter 6, I examine the debates around CCTV testimony, which demonstrate a consistency of belief in live or ‘face-to-face’ confrontation to produce juridical ‘Truth’ that can be traced back over 800 years. The final chapter of this thesis examines sexual assault trials. This chapter brings together all of these sources of anxiety. Although often termed ‘exceptional’, sexual assault trials highlight how essential live performance is to manufacturing the authority of ‘The Law’ through the weight given to demeanour assessment, and because these trials make visible the sustained symbolic violence characteristic of adversarial criminal trials that is particularly traumatic for sexual assault complainants. Examination of sexual assault trials also reveals the double-edged position of performance in the trial. The exploitation of the symbolic value of live performance is the source of much trauma, yet the performance of tradition is also essential to maintaining popular belief in the adversarial criminal jury trial

Discourse and Configurations of Gender

My research paper is an investigation of the discourse of gender in relation to the work of Michel Foucault, Susan Bordo, Judith Butler and the artists Louise Bourgeois, Fiona Hall, Jo Spence and Neil Emmerson. I have applied Foucault's notion of the formation, necessity and operations of discourses as the basis from which ideas can be articulated, and the context within which notions of gender are formulated and challenged. I examine the processes in discourses, such as the imposition of disciplines to control the subject, which in turn are inscribed in the body of the subject by the subject, as they begin to perceive and define themselves in terms of the disciplines. I use this theory on the relationship between discourse-power-knowledge to analyse my work and that of the artists mentioned. The work of each artist is discussed in terms of the discourse of gender and the basis from which they critique its power, its effects on bodies and forms of representation through a marginal discourse. For the purposes of my work, the conclusion reached is that to disrupt the discourse of gender entails a continual questioning and awareness of its 'truths,' processes and effects. Description of Studio Work: The three major works examine the power and operations of the discourse of gender on bodies and how marginal discourses subvert these constructions. My works in paper, printmedia and metal, in two dimensions and three, reflect the effects through forms that seek to question limitations and extend our conception of male and female bodies. The wall piece, Out of Order, re-configures symbols and signs from the discourse of gender as a means of disrupting notions that gender is immutable. A swirling red line is woven through a densely layered mass of horizontal broken lines. The addition of symbols, X and Y chromosomes, numbers and other tokens of gender, appear at various points in this marginal discourse on conception of 'bodies.' Mammaphone, which accompanies Out of Order and Bullrushes, consists of an enlarged breast LP playing on a turntable. The 'tracks' are a litany of terms for the breast from slang and maternal discourses. The turntable that 'hosts' the LP sits on top of a stylised 'flight recorder's black box,' which suggests the hidden discourse on gender. Bullrushes, is an arrangement of 20 phallic-like forms each on a flexible metal rod that sways with the passage of air around the work. The work presents male bodies as durable, delicate and vulnerable despite the norms of the masculine discourse. The intention is to put into process an interrogation of the effects of gender on bodies and the possibilities for re-thinking the discourse of gender

Development of endotoxin tolerance does not influence the response to a challenge with the mucosal live-attenuated influenza vaccine in humans in vivo

Introduction: The effects of bacterial infections on the response to subsequent viral infections are largely unknown. This is important to elucidate to increase insight into the pathophysiology of bacterial and viral co-infections, and to assess whether bacterial infections may influence the course of viral infections. Methods: Healthy male subjects received either bacterial endotoxin [Escherichia coli-derived lipopolysaccharide (LPS), 2 ng/kg, n = 15] or placebo (n = 15) intravenously, followed by intranasal Fluenz (live-attenuated influenza vaccine) 1 week later. Results: LPS administration resulted in increased plasma cytokine levels and development of endotoxin tolerance in vivo and ex vivo, illustrated by attenuated cytokine production upon rechallenge with LPS. Following Fluenz administration, infectivity for the Fluenz A/B strains was similar between the LPS-Fluenz and placebo-Fluenz groups (13/15 subjects in both groups). Also, the Fluenz-induced increase in temperature and IL-6, G-CSF and IP-10 concentrations in nasal wash were similar between both groups. Conclusion: While endotoxemia profoundly attenuates the immune response upon a second LPS challenge, it does not influence the Fluenz-induced immune response. These results suggest immune suppression after bacterial infection does not alter the response to a subsequent viral infection

Trained Immunity Confers Broad-Spectrum Protection Against Bacterial Infections.

The innate immune system recalls a challenge to adapt to a secondary challenge, a phenomenon called trained immunity. Training involves cellular metabolic, epigenetic and functional reprogramming, but how broadly trained immunity protects from infections is unknown. For the first time, we addressed whether trained immunity provides protection in a large panel of preclinical models of infections. Mice were trained and subjected to systemic infections, peritonitis, enteritis, and pneumonia induced by Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Citrobacter rodentium, and Pseudomonas aeruginosa. Bacteria, cytokines, leukocytes, and hematopoietic precursors were quantified in blood, bone marrow, and organs. The role of monocytes/macrophages, granulocytes, and interleukin 1 signaling was investigated using depletion or blocking approaches. Induction of trained immunity protected mice in all preclinical models, including when training and infection were initiated in distant organs. Trained immunity increased bone marrow hematopoietic progenitors, blood Ly6Chigh inflammatory monocytes and granulocytes, and sustained blood antimicrobial responses. Monocytes/macrophages and interleukin 1 signaling were required to protect trained mice from listeriosis. Trained mice were efficiently protected from peritonitis and listeriosis for up to 5 weeks. Trained immunity confers broad-spectrum protection against lethal bacterial infections. These observations support the development of trained immunity-based strategies to improve host defenses

Refined mapping of autoimmune disease associated genetic variants with gene expression suggests an important role for non-coding RNAs

Genome-wide association and fine-mapping studies in 14 autoimmune diseases (AID) have implicated more than 250 loci in one or more of these diseases. As more than 90% of AID-associated SNPs are intergenic or intronic, pinpointing the causal genes is challenging. We performed a systematic analysis to link 460 SNPs that are associated with 14 AID to causal genes using transcriptomic data from 629 blood samples. We were able to link 71 (39%) of the AID-SNPs to two or more nearby genes, providing evidence that for part of the AID loci multiple causal genes exist. While 54 of the AID loci are shared by one or more AID, 17% of them do not share candidate causal genes. In addition to finding novel genes such as ULK3, we also implicate novel disease mechanisms and pathways like autophagy in celiac disease pathogenesis. Furthermore, 42 of the AID SNPs specifically affected the expression of 53 non-coding RNA genes. To further understand how the non-coding genome contributes to AID, the SNPs were linked to functional regulatory elements, which suggest a model where AID genes are regulated by network of chromatin looping/non-coding RNAs interactions. The looping model also explains how a causal candidate gene is not necessarily the gene closest to the AID SNP, which was the case in nearly 50% of cases
