False Forms and Wicked Women: Apuleius’ Isis Book and Ovid’s Iphis Story

In this thesis, I take a new approach to the study of Isis in Apuleius’ Golden Ass by comparing the novel to the story of Iphis written by Ovid in the Metamorphoses. I begin by reviewing the history of Isiac worship in the Roman world and previous research on Isis’ role in Apuleius. I then move on to a detailed study of literary allusions between the Golden Ass and Ovid’s Iphis story. From there, I explore the literary evidence concerning Isiac ethics and use my findings to analyze further the two texts at hand. I argue that both Apuleius and Ovid use Isis to mitigate the effects of dishonorable conduct in their narratives, especially that of a sexual nature. In each story, Isis ensures that her followers avoid behavior that disrupts communal and familial life, ultimately reinforcing traditional morality and social norms.Master of Art

The Trauma of Ovid’s Mythic Women: Rape, Captivity, Silence

Ovid’s poetry contains an inordinate number of mythic rape episodes and allusions to rape. Rape—especially divine rape—is a common topos in Graeco-Roman mythology, but not every ancient writer approaches it in the same way. Ovid, contrary to his predecessors and contemporaries, focuses especially on the female victims of rape and on the variety of their traumatic experiences. In this dissertation, I discuss select rape victims from Ovid’s mythical works—the Heroides, the Metamorphoses, and the Fasti—and analyze his narratives through the lens of trauma theory. In his more detailed accounts of sexual violence, he describes not only the peritraumatic symptoms of female victims, but also post-traumatic symptoms. When faced with the threat of rape, Ovidian women may fight their attackers, freeze (voluntarily or involuntarily), attempt to flee, or dissociate. After rape, their responses are just as varied: Briseis becomes trauma-bonded to her captor (Heroides 3), Io recovers and returns to her family (Met. 1), Philomela takes revenge on her rapist (Met. 6), Lucretia commits suicide (Fasti 2), and the Sabine women settle into their forced marriages (Fasti 3).For each of the chosen rape episodes, I perform a literary analysis of Ovid’s text and compare his language to that of modern western accounts of peritraumatic experiences and PTSD symptoms associated with sexual violence. Ovid’s attention to the multiplicity of rape trauma symptoms indicates a general interest in the lived experience of oppressed people, but more specifically in the experience of women. The similarities between his rape tales and modern psychological rape trauma studies further show that he had some fundamental understanding of how rape can impact a victim’s body and mind.Doctor of Philosoph

The dynamics of language and ethnicity in Mauritius

The link between ethnicity and language has been well established in research but its contextual, perspectual and variable nature demands that this connection be re-examined in each attempt to understand a nation. This paper is about Mauritius, a postcolonial context where French and British colonisation has left salient features which continue to influence the dynamics around language and ethnicity in the country. By describing its demographic characteristics and its linguistic and political situation, I retrieve some of the key facets of this multi-ethnic and multi-lingual nation which evidence resistance by both the state and the populace against the established colonial languages. To compensate for the lack of appropriate theoretical framework in existing research on Mauritius, I use Homi Bhabha’s postcolonial theoretical framework to uncover the realities faced by both the state and the people of this country and the impacts these may have in the workplace

Extracellular VirB5 Enhances T-DNA Transfer from Agrobacterium to the Host Plant

VirB5 is a type 4 secretion system protein of Agrobacterium located on the surface of the bacterial cell. This localization pattern suggests a function for VirB5 which is beyond its known role in biogenesis and/or stabilization of the T-pilus and which may involve early interactions between Agrobacterium and the host cell. Here, we identify VirB5 as the first Agrobacterium virulence protein that can enhance infectivity extracellularly. Specifically, we show that elevating the amounts of the extracellular VirB5—by exogenous addition of the purified protein, its overexpression in the bacterium, or transgenic expression in and secretion out of the host cell—enhances the efficiency the Agrobacterium-mediated T-DNA transfer, as measured by transient expression of genes contained on the transferred T-DNA molecule. Importantly, the exogenous VirB5 enhanced transient T-DNA expression in sugar beet, a major crop recalcitrant to genetic manipulation. Increasing the pool of the extracellular VirB5 did not complement an Agrobacterium virB5 mutant, suggesting a dual function for VirB5: in the bacterium and at the bacterium-host cell interface. Consistent with this idea, VirB5 expressed in the host cell, but not secreted, had no effect on the transformation efficiency. That the increase in T-DNA expression promoted by the exogenous VirB5 was not due to its effects on bacterial growth, virulence gene induction, bacterial attachment to plant tissue, or host cell defense response suggests that VirB5 participates in the early steps of the T-DNA transfer to the plant cell

Rethinking non-traditional resistance at work : the case of the Indian Diaspora in Mauritius

Resistance at work can take many forms and this is reflected in the multiple ways it has been theorised in research. In this paper, I use postcolonial theory to analyse employee resistance in Mauritius. To do this, I deploy Homi Bhabha’s concepts of mimicry, ambivalence and hybridity to explore non-traditional forms of resistance among the Indian Diaspora working in the hotel industry. Using ethnographic research, I firstly look at its ‘home’-making practices as it is within the home that visions of community emerge (Bhabha, 1994) which could later influence behaviours at work. I argue that the Diaspora maintains connections with its ancestral roots via routine religious practices and language use while concomitantly resisting assimilation in the local context. The analysis is then extended to their workplace where further forms of non-traditional resistance are found to be enacted which are strongly influenced by the same values emerging at home

HSPVdb—the Human Short Peptide Variation Database for improved mass spectrometry-based detection of polymorphic HLA-ligands

T cell epitopes derived from polymorphic proteins or from proteins encoded by alternative reading frames (ARFs) play an important role in (tumor) immunology. Identification of these peptides is successfully performed with mass spectrometry. In a mass spectrometry-based approach, the recorded tandem mass spectra are matched against hypothetical spectra generated from known protein sequence databases. Commonly used protein databases contain a minimal level of redundancy, and thus, are not suitable data sources for searching polymorphic T cell epitopes, either in normal or ARFs. At the same time, however, these databases contain much non-polymorphic sequence information, thereby complicating the matching of recorded and theoretical spectra, and increasing the potential for finding false positives. Therefore, we created a database with peptides from ARFs and peptide variation arising from single nucleotide polymorphisms (SNPs). It is based on the human mRNA sequences from the well-annotated reference sequence (RefSeq) database and associated variation information derived from the Single Nucleotide Polymorphism Database (dbSNP). In this process, we removed all non-polymorphic information. Investigation of the frequency of SNPs in the dbSNP revealed that many SNPs are non-polymorphic “SNPs”. Therefore, we removed those from our dedicated database, and this resulted in a comprehensive high quality database, which we coined the Human Short Peptide Variation Database (HSPVdb). The value of our HSPVdb is shown by identification of the majority of published polymorphic SNP- and/or ARF-derived epitopes from a mass spectrometry-based proteomics workflow, and by a large variety of polymorphic peptides identified as potential T cell epitopes in the HLA-ligandome presented by the Epstein–Barr virus cells

Reaction mechanism for the replacement of calcite by dolomite and siderite: Implications for geochemistry, microstructure and porosity evolution during hydrothermal mineralisation

Carbonate reactions are common in mineral deposits due to CO2-rich mineralising fluids. This study presents the first in-depth, integrated analysis of microstructure and microchemistry of fluid-mediated carbonate reaction textures at hydrothermal conditions. In doing so, we describe the mechanisms by which carbonate phases replace one another, and the implications for the evolution of geochemistry, rock microstructures and porosity. The sample from the 1.95 Moz Junction gold deposit, Western Australia, contains calcite derived from carbonation of a metamorphic amphibole—plagioclase assemblage that has further altered to siderite and dolomite. The calcite is porous and contains iron-rich calcite blebs interpreted to have resulted from fluid-mediated replacement of compositionally heterogeneous amphiboles. The siderite is polycrystalline but nucleates topotactically on the calcite. As a result, the boundaries between adjacent grains are low-angle boundaries (<10°), which are geometrically similar to those formed by crystal–plastic deformation and recovery. Growth zoning within individual siderite grains shows that the low-angle boundaries are growth features and not due to deformation. Low-angle boundaries develop due to the propagation of defects at grain faces and zone boundaries and by impingement of grains that nucleated with small misorientations relative to each other during grain growth.The cores of siderite grains are aligned with the twin planes in the parent calcite crystal showing that the reactant Fe entered the crystal along the twin boundaries. Dolomite grains, many of which appear to in-fill space generated by the siderite replacement, also show alignment of cores along the calcite twin planes, suggesting that they did not grow into space but replaced the calcite. Where dolomite is seen directly replacing calcite, it nucleates on the Fe-rich calcite due to the increased compatibility of the Fe-bearing calcite lattice relative to the pure calcite. Both reactions are interpreted as fluid-mediated replacement reactions which use the crystallography and elemental chemistry of the calcite. Experiments of fluid-mediated replacement reactions show that they proceed much faster than diffusion-based reactions. This is important when considering the rates of reactions relative to fluid flow in mineralising systems
