READING AND RESPONDING: FINDING AND MAKING MEANING IN THE LIFE WRITING OF DIASPORIC IRANIAN JEWISH WOMEN

This project investigates the English-language life writing of diasporic Iranian Jewish women. It examines how these women have differentially imagined their diasporic lives and travels, and how they have in turn been imagined and accepted or rejected by their audiences. In the first chapter, I use “home” as a lens for understanding three distinct life writing texts, showing how the authors write about what it means to have a home and to be at home in contrasting and even contradictory ways. I show how, despite potential hegemonic readings that perpetuate unequal relationships and a normative definition of the ideal home, the texts are open to multiple contestatory readings that create spaces for new formulations and understandings. In the second chapter, I look more closely at the intersections between trauma stories and the life writing of Iranian Jewish women, and I argue that readers use life writing texts about trauma to support an egocentric reconstruction of American democracy and dominance. I also show how a critical frame for understanding trauma can yield interpretations that highlight, rather than ignore, relationships of power and privilege. In the final chapter of the thesis, I present a case study of two online reading groups, and I show that communal reading environments, though they participate in dominant discourses, are also spaces where resistance and subversion can develop.

The Global Politics of Contemporary Travel Writing

To what extent do bestselling travel books, such as those by Paul
Theroux, Bill Bryson, Bruce Chatwin and Michael Palin, tell us as
much about world politics as newspaper articles, policy documents and
press releases? Debbie Lisle argues that the formulations of genre,
identity, geopolitics and history at work in contemporary travel writing
are increasingly at odds with a cosmopolitan and multicultural world in
which ‘everybody travels’. Despite the forces of globalisation, common
stereotypes about ‘foreignness’ continue to shape the experience of
modern travel. The Global Politics of Contemporary Travel Writing is
concerned with the way contemporary travelogues engage with, and try
to resolve, familiar struggles in global politics such as the protection of
human rights, the promotion of democracy, the management of
equality within multiculturalism and the reduction of inequality. This is
a thoroughly interdisciplinary book that draws from international
relations, literary theory, political theory, geography, anthropology and
history.

Discovery of an RNA virus 3'->5' exoribonuclease that is critically involved in coronavirus RNA synthesis

Replication of the giant RNA genome of severe acute respiratory syndrome (SARS) coronavirus (CoV) and synthesis of as many as eight subgenomic (sg) mRNAs are mediated by a viral replicase-transcriptase of outstanding complexity that includes an essential endoribonuclease activity. Here, we show that the CoV replicative machinery, unlike that of other RNA viruses, also uses an exoribonuclease (ExoN) activity, which is associated with nonstructural protein (nsp) 14. Bacterially expressed forms of SARS-CoV nsp14 were shown to act on both ssRNAs and dsRNAs in a 3'5' direction. The activity depended on residues that are conserved in the DEDD exonuclease superfamily. The protein did not hydrolyze DNA or ribose-2'-O-methylated RNA substrates and required divalent metal ions for activity. A range of 5'-labeled ssRNA substrates were processed to final products of 8–12 nucleotides. When part of dsRNA or in the presence of nonlabeled dsRNA, the 5'-labeled RNA substrates were processed to significantly smaller products, indicating that binding to dsRNA in cis or trans modulates the exonucleolytic activity of nsp14. Characterization of human CoV 229E ExoN active-site mutants revealed severe defects in viral RNA synthesis, and no viable virus could be recovered. Besides strongly reduced genome replication, specific defects in sg RNA synthesis, such as aberrant sizes of specific sg RNAs and changes in the molar ratios between individual sg RNA species, were observed. Taken together, the study identifies an RNA virus ExoN activity that is involved in the synthesis of multiple RNAs from the exceptionally large genomic RNA templates of CoVs.
