  • Inverse Operations
    Inverse Operations: Sinful Lust and Salvific Virginity in Central Italian Imagery of the Second Eve by Colleen Bache A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Arts Approved April 2015 by the Graduate Supervisory Committee: Corine Schleif, Chair Anne Derbes Renzo Baldasso ARIZONA STATE UNIVERSITY May 2015 ABSTRACT Eighteen late medieval central Italian paintings featuring the figure of Eve reclining on the ground beneath the enthroned Virgin have been the center of a decades- long debate among scholars. The dispute centers on whether the imagery depicts Mary as Eve's counterpart in the role of virgin mother or intercessor as the Second Eve. I argue that these two possibilities are not mutually exclusive and instead support one another. I maintain that Eve and Mary appear as opposites according to their contrasting sexual statuses because their antithesis lies at the center of the theology of the Second Eve and the heart of the signification of these paintings. Though frequently overlooked, my exploration of this imagery begins with the attributes used to identify Eve: the woman- headed serpent, the fig, and clothing. Specifically, I analyze the relationship between the particular attributes employed and the theological interpretation of the Fall as a result of concupiscent sexual intercourse. My study then turns to the individual imagery of the central figure of Mary and its reference to church teachings. Appearing amidst allusions to the Annunciation and with emblems of her roles as mother and queen, the Marian imagery in these eighteen paintings specifically reiterates the dogma of her perpetual virginity.

The Politics of Exile: Ama Ata Aidoo's Our Sister Killjoy Abstract Ama Ata Aidoo's Our Sister Killjoy or Reflections from a Black-Eyed Squint is a relentless attack on the notions of exile as relief from the societal constraints of national development and freedom to live in a cultural environment conducive to creativity. In this personalized prose/poem, Aidoo questions certain prescribed theories of exile (including the reasons for exile)—particularly among African men. The novel exposes a rarely heard viewpoint in literature in English—that of the African woman exile. Aidoo's protagonist Sissie, as the "eye" of her people, is a sojourner in the "civilized" world of the colonizers.

  • Skins and the Impossibility of Youth Television
    Skins and the impossibility of youth television David Buckingham This essay is part of a larger project, Growing Up Modern: Childhood, Youth and Popular Culture Since 1945. More information about the project, and illustrated versions of all the essays, can be found at: https://davidbuckingham.net/growing-up-modern/. In 2007, the UK media regulator Ofcom published an extensive report entitled The Future of Children’s Television Programming. The report was partly a response to growing concerns about the threats to specialized children’s programming posed by the advent of a more commercialized and globalised media environment. However, it argued that the impact of these developments was crucially dependent upon the age group. Programming for pre-schoolers and younger children was found to be faring fairly well, although there were concerns about the range and diversity of programming, and the fate of UK domestic production in particular. Nevertheless, the impact was more significant for older children, and particularly for teenagers. The report was not optimistic about the future provision of specialist programming for these age groups, particularly in the case of factual programmes and UK- produced original drama. The problems here were partly a consequence of the changing economy of the television industry, and partly of the changing behaviour of young people themselves. As the report suggested, there has always been less specialized television provided for younger teenagers, who tend to watch what it called ‘aspirational’ programming aimed at adults. Particularly in a globalised media market, there may be little money to be made in targeting this age group specifically.

This essay examines the tactile relationship between this changeable skin-creature, and the figures of the taxidermist and the curator in the turn of the twentieth century museum. Using Bristol Museum as a case study, it argues that specimens were not inert or stilled within museum collections. It explores how taxidermy specimens were meeting places between animal remains and human bodies, as curators sought to remount existing specimens, and prevent them from deteriorating further. Taking a material approach, it examines how animal skins were physically shaped by human hands, and figuratively woven into stories of science, the British Empire, and the natural world.

  • Virginity and the Patristic Tradition; Spenser’S Faerie Queene and the Reformation
    Virginity and the Patristic Tradition; Spenser’s Faerie Queene and the Reformation —————— Beatrice Fannon Thesis Submitted in Candidature for the Degree of Doctor of Philosophy Cardiff University —————— July 2012 Summary It has long been recognised that chastity is a problem in Book III of The Faerie Queene. The problem arises in part because the poem does not clearly define chastity but instead ambiguously praises it both as virginity and marital love. Behind the poem, too, lies the problem of Elizabeth with her Protestant virginity sometimes represented in Britomart, sometimes in Belphoebe, but also dangerously Catholic in its iconography. Indeed, wherever we turn in The Faerie Queene there are tangles of meaning. The contention of this thesis is that these problems are not merely surface writings, but stem from the Protestant breach with the Church Fathers and the long history of virginity. That history, I suggest in the main body of the thesis, has been broadly ignored by the critics who, by failing to grasp its theological complexity and development, have failed to produce an adequate platform from which to read the Protestant reformers and The Faerie Queene. The thesis is divided into two main parts. The Introduction examines recent critical discussions of virginity in Spenser, the Middle Ages and patristics, thus working backwards historically to the patristic writings themselves where I offer, in Part I, a detailed examination of the growth of the theological significance of virginity. Part II then looks at the reformers’ attacks on virginity, Luther and Erasmus especially, before turning to a discussion of the troubled meanings of virginity and chastity in Spenser’s epic poem.

Auxiliary Skins is, in fact, about feeling in all of its shades of meaning, from the physical to the pro- foundly emotional. For example, in “Skin Just,” the sim- ple marks on the protagonist’s skin are turned into ob- sessively growing, cancerous thoughts, which cannot be eradicated; in “Breached Heredity,” on the other hand, a young woman’s pregnancy hides, and at the same time exposes, the twisted tangles of her family life; and the second-hand clothes in a vintage shop, with stories of their own, are the triggers of cause-effect chains ending in tragedy—with hints of irony—in “Plungers, Porce- lain, and Paltry Things.” Miscione experiments audaciously in her writ- ing: some of her stories choose eccentric points of view that completely disorient and estrange the reader. In “Uterine Kisses,” for example, the narrating voice comes from within the deforming glass walls of an incuba- tor.
