‘Depending on where I am…’ Hair, travelling and the performance of identity among Black and mixed‐race women
Get PDFA growing interdisciplinary literature examines the role of hair textures and styles in Black and mixed-race women's identity performances. Through an analysis of travel narratives, this paper extends and complements research on the context-dependency of racialized identity performances. This paper presents an analysis of 24 qualitative interviews with Black and mixed-race women in England and Germany. The question it seeks to answer is: ‘How do changes in context alter Black and mixed-race women's hairstyling practices as a performance of identity?’ Navigating a novel context could lead the women to (1) conform to local standards of beauty and femininity, (2) resist external expectations, (3) try out novel performances and (4) negotiate the complex performance of belonging. All in all, this paper shows that Black and mixed-race women dialogically re/negotiated and performatively re/created how they identify and how they are identified by others as they moved from one context to another
Graphene and its derivatives: a review and graphene growth on insulating substrates via nickel diffusion
No full textThis thesis is composed of a review on the rapidly growing field of graphene research and an experimental investigation of a synthesis method to produce high quality graphene on insulating substrates via diffusion of carbon through nickel. The history, synthesis, characterization, properties, and applications of graphene and its derivatives are comprehensively discussed in the review. Historical milestones span the first theoretical publication on graphene in 1947 to K. S. Novoselov and A. K. Geim’s groundbreaking discovery in 2004. A variety of physical and chemical synthesis techniques have been discovered, each with their own advantages and disadvantages. Several forms of microscopy and spectroscopy have been utilized to realize the material’s exceptional structural, electronic, optical, mechanical, and thermal properties. Together, these qualities have justified graphene thin films’ capability to be integrated into a widespread collection of electronic devices. The objective of the experimental section is to explore a novel synthesis procedure entailing the spin coating of a carbon solution onto a thermally evaporated 40 nm layer of nickel on a SiO2/Si substrate. The samples were annealed at 50°C, 100°C, 150°C, 200°C, or 400°C for 4 hours to initiate the diffusion of carbon through the metal and deposition onto the substrate. Etching of the metal and excess carbon source material took place in a 5:1 HCl and HNO3 solution. Distinctive D, G, and 2D peaks at around 1350 cm-1, 1580 cm-1, and 2700 cm-1 in the Raman spectra indicated the material was graphitic, but an increasing slope in the Raman shift suggested that the nickel layer was still present. 2D/G integrated intensity area ratios showed a peak somewhere between 100° and 150°C, which implied an ideal growth temperature within that range. D/G area ratios exhibited unexpected and questionable behavior. Despite these inconclusive results, a recent paper by Kwak et al proposing a similar growth method did in fact prove that high quality few layer graphene sheets can be successfully produced via this technique. A brief review of that paper is included.M.S.Includes bibliographical referencesby Juliet L Defin
Intermittent Fasting Promotes Fat Loss with Lean Mass Retention, Increased Hypothalamic Norepinephrine Content, and Increased Neuropeptide Y Gene Expression in Diet-Induced Obese Male Mice
No full textClinical studies indicate alternate day, intermittent fasting (IMF) protocols result in meaningful weight loss in obese individuals. To further understand the mechanisms sustaining weight loss by IMF, we investigated the metabolic and neural alterations of IMF in obese mice. Male C57/BL6 mice were fed a high-fat diet (HFD; 45% fat) ad libitum for 8 weeks to promote an obese phenotype. Mice were divided into 4 groups and either maintained on ad libitum HFD (HFD), received alternate day access to HFD (IMF- HFD), switched to ad libitum low fat diet (LFD; 10% fat), or received IMF of LFD (IMF- LFD). After 4 weeks, IMF-HFD (~13%) and IMF-LFD (~18%) had significantly lower body weights than HFD. Body fat was also lower (~40-52%) in all diet interventions. Lean mass was increased in the IMF-LFD (~12-13%) compared with HFD and IMF-HFD groups. Oral glucose tolerance AUC was lower in the IMF-HFD (~50%), whereas insulin tolerance AUC was reduced in all diet interventions (~22-42%). HPLC measurements of hypothalamic tissue homogenates indicated higher (~55-60%) norepinephrine (NE) content in the anterior regions of the medial hypothalamus of IMF compared with ad libitum fed groups, whereas NE content was higher (~19-32%) in posterior regions in the IMF-LFD group only. Relative gene expression of Npy in the arcuate nucleus was increased (~65-75%) in IMF groups. Our novel findings indicate that intermittent fasting produces alterations in hypothalamic NE and NPY, suggesting an involvement in the counter regulatory processes of short-term weight loss are associated with an IMF dietary strategy.Peer reviewe
What Do Shakespearean Musicians Think? Complementary Rhetorical Devices in <i>Romeo and Juliet</i> and Byrd’s <i>O that most rare breast</i>
Get PDFIn Act 4, scene 5 of Romeo and Juliet, Shakespeare used the rhetorical figure of catachresis to capture the meta-theatrical thoughts of musicians as a way of expressing the “uncomfortable time” of Juliet’s apparent death on her wedding day. It is possible to trace Shakespeare’s source for the scene to O that most rare breast, William Byrd’s extensive dirge for Sir Philip Sidney. Not only does the song provide musical and funereal material, it also invites a writer’s response, as Byrd used a cross-disciplinary form of eristic imitation to outdo the rhetorical achievement of his text’s unnamed author.</p
‘The art of salvation is but the art of memory’ : soul-agency, remembrance and expression in Donne and Shakespeare
Get PDFThis thesis examines how the dislocation of old beliefs in post-Reformation England affected perceptions of the soul in the work of Donne and Shakespeare. The introduction, using Augustinian discourses on the tri-partite soul, explores how the soul is imagined in post-Reformation England. Current debates on interiority, the climate of anxiety that surrounds religious upheaval, historical readings of the composition of the soul and the problems of its actual representation on the page and stage are discussed. The patterning of Augustine‟s tri-partite model of Reason, Will and Memory is examined, and the regenerative power of concordant Memory that can bind together a harmonic trinity is offered as a solution to the fractured soul. The first part of the thesis concentrates on writings that represent Donne‟s anxieties over the fate of the soul as he contemplates conversion from Catholicism to the new religious order. Chapter One is an enquiry into his unpublished works from 1601 to 1611 and examines the idea of the wandering soul, from The Progresse of the Soule, to the Divine Poems and finally to the redeemed soul seen in the form of Elizabeth Drury in the Anniversaries. In this chapter, I argue that Donne is searching for an alternative Marian aesthetic as he leaves behind his Catholic past, a new image of divine intercession for the Protestant world that might offer him comfort and a route to salvation. Chapter Two explores his very public sermons after he enters the ministry until his death. Here, a pattern of redemption is argued through the salvic properties of the living Word of the sermon that is relayed through the performative power of the preacher. The preacher‟s working space and the power of the Word to viscerally transform the congregation are central here to the soul‟s salvation. The second part examines how Shakespeare explores the „journey‟ of the soul through a selection of his plays, but where the limits of genre impose restrictions on Shakespeare‟s development of an image of redemption. Chapter Three examines the wandering soul in The Merchant of Venice and Othello. Through the trope of marriage, the fate of the souls of Jessica and Othello are explored as they find themselves marginalized in an inhospitable Venice, while their pasts have been forgotten in the attempt to convert to Christianity. Chapter Four explores the use of the female character as an image of Memory that can generate hope, reading Juliet in Romeo and Juliet and Cordelia in King Lear as “soul agents”, whose beneficence can bring about redemptive change. However, the thesis argues that the genre of tragedy examined here limits the soul agent. Chapter Five argues for an alternative genre that opens up the possibilities for the successful portrayal of the soul agent. In the romance plays, the representation of the soul can be seen working successfully to a redemptive conclusion. Romance dramas foreground their slippages in plot and take us into dreamscapes at the centre of which is an essential female influence. Marina in Pericles, Perdita in The Winter‟s Tale, Innogen in Cymbeline and Ariel/Miranda in The Tempest provide a link with Donne‟s presentation of the soul as female in the Anniversaries. Both Donne and Shakespeare suggest the idea of the female in literature as a redemptive figure, away from earlier discourses on the soul that finds itself at the mercy of epistemological wrangling. Donne and Shakespeare re-instate that sacredness and place it within art as an image of Memory, a vital component of Augustine‟s tri-partite soul, but also as an active and vibrant image of possibilit
