Juliet - a role in four movies

Over a period of sixty years, between 1936 and 1996, there were numerous filmed versions of Shakespeare’s Romeo and Juliet, but four in particular were made for and obtained a worldwide commercial release. George Cukor’s lavish production of 1936 with Norma Shearer as Juliet was the first feature length, big budget, ‘talkie’ of Shakespeare’s play to be made by a major studio and aimed at the cinema going public. Shearer remains, to this day, the only actress of the modern age who was a major film star when cast in the role of Juliet. In direct contrast to this, Renato Castellani’s Anglo Italian neo-realist, retrospective 1954 adaptation featured an unknown Susan Shentall, who had never acted before filming and, on completion of the film, retired and never acted again. Franco Zeffirrelli’s sweeping 1968 production with Olivia Hussey as Juliet was a worldwide commercial success and is still revered by many as being the authoritative film experience of the play. Baz Luhrmann’s1996 version, with Claire Danes playing opposite Leonardo DiCaprio, was initially decried as an affront to Shakespeare’s masterpiece and the director was accused of sacrificing the text for a highly stylised and bombastic shallow content. It is only recently that this film has been viewed by critics and academics alike in a more sympathetic and positive manner. These films, taken individually, present to us a particular performance of the ‘Juliet’ of Shakespeare’s text; but in addition to this they allow us a comparative study of the portrayal of Juliet as a celluloid reflection of the idealised woman shaped by the progressive demands of the contemporary phallocentric society in the western world. Patricia White examined this reflection theory in Feminism and Film and, in turn, referred to the studies of Molly Haskell and Marjorie Rosen in the early 1970s, and quoted them on the basis that film ‘reflects social reality, that depictions of women in film mirror how society treats women, that these depictions are distortions of how women ‘“really are” and what they “really want” ’(White 118). The theory explores the supposition that women are repeatedly and systematically portrayed in a catalogue of images that compels the viewer to see and accept them in a typology of roles which, according to White, reinforces the phallocentric ideology of women as an array of ‘virgins, vamps, victims, suffering mothers, child women and sex kittens’(White 118). A question that therefore arises and which is central to this thesis is how, specifically, has Juliet been portrayed in film? Has the Juliet of the screen been nothing more than an object of visual stimulation, an object of the scopophilic gaze and male sexual fantasy? If this is the case, how does this vary in each of the filmed versions listed? We must also consider how Juliet exists in relation to other characters in the play beyond her direct involvement with Romeo. Juliet’s role is pivotal within the play even though she does not have the most lines. She has a direct influence on Mercutio and his relationship to Romeo, even though Juliet and Mercutio fail to exchange a single line of dialogue in the entire play. Juliet’s relationship with Romeo is altered dramatically in the aftermath of Mercutio’s death. Juliet’s life is also influenced by her relationships with others such as the Nurse and Friar Laurence, each of whom will abandon her at some point in the play. How are these relationships played and interpreted in each of the films in question? One cannot write extensively of Juliet if one limits oneself to writing exclusively of her. Each of these characters and how they are portrayed needs also to be examined. So too must the directors, all male, be examined in some detail. How much do they alter the Juliet of Shakespeare’s text and for what purpose

Weak Transversality and Partially Invariant Solutions

New exact solutions are obtained for several nonlinear physical equations, namely the Navier-Stokes and Euler systems, an isentropic compressible fluid system and a vector nonlinear Schroedinger equation. The solution methods make use of the symmetry group of the system in situations when the standard Lie method of symmetry reduction is not applicable.Comment: 23 pages, preprint CRM-284

Multiscale, multimodal analysis of tumor heterogeneity in IDH1 mutant vs wild-type diffuse gliomas.

Glioma is recognized to be a highly heterogeneous CNS malignancy, whose diverse cellular composition and cellular interactions have not been well characterized. To gain new clinical- and biological-insights into the genetically-bifurcated IDH1 mutant (mt) vs wildtype (wt) forms of glioma, we integrated data from protein, genomic and MR imaging from 20 treatment-naïve glioma cases and 16 recurrent GBM cases. Multiplexed immunofluorescence (MxIF) was used to generate single cell data for 43 protein markers representing all cancer hallmarks, Genomic sequencing (exome and RNA (normal and tumor) and magnetic resonance imaging (MRI) quantitative features (protocols were T1-post, FLAIR and ADC) from whole tumor, peritumoral edema and enhancing core vs equivalent normal region were also collected from patients. Based on MxIF analysis, 85,767 cells (glioma cases) and 56,304 cells (GBM cases) were used to generate cell-level data for 24 biomarkers. K-means clustering was used to generate 7 distinct groups of cells with divergent biomarker profiles and deconvolution was used to assign RNA data into three classes. Spatial and molecular heterogeneity metrics were generated for the cell data. All features were compared between IDH mt and IDHwt patients and were finally combined to provide a holistic/integrated comparison. Protein expression by hallmark was generally lower in the IDHmt vs wt patients. Molecular and spatial heterogeneity scores for angiogenesis and cell invasion also differed between IDHmt and wt gliomas irrespective of prior treatment and tumor grade; these differences also persisted in the MR imaging features of peritumoral edema and contrast enhancement volumes. A coherent picture of enhanced angiogenesis in IDHwt tumors was derived from multiple platforms (genomic, proteomic and imaging) and scales from individual proteins to cell clusters and heterogeneity, as well as bulk tumor RNA and imaging features. Longer overall survival for IDH1mt glioma patients may reflect mutation-driven alterations in cellular, molecular, and spatial heterogeneity which manifest in discernable radiological manifestations

Increased Rate of CD4+ T-Cell Decline and Faster Time to Antiretroviral Therapy in HIV-1 Subtype CRF01_AE Infected Seroconverters in Singapore

It remains controversial as to whether HIV-1 subtypes influence disease progression. Singapore offers a unique opportunity to address this issue due to the presence of co-circulating subtypes. We compared subtype CRF01_AE and non-CRF01_AE infected patients, with regards to estimated annual rate of CD4+ T-cell loss and time from estimated data of seroconversion (EDS) to antiretroviral therapy (ART).We recruited ART-naive patients with known dates of seroconversion between October 2002 and December 2007 at the Singapore Communicable Disease Centre, the national reference treatment centre. Multilevel mixed-effects models were used to analyse the rate of CD4+ T-cell decline. Time from EDS to ART was analyzed with the Kaplan-Meier survival method and compared with Cox proportional hazards models. viral load.Infecting subtype significantly impacted the rate of CD4+ T-cell loss and time to treatment in this cohort. Studies to understand the biological basis for this difference could further our understanding of HIV pathogenesis

Oscillations of neutrinos and mesons in quantum field theory

This report deals with the quantum field theory of particle oscillations in vacuum. We first review the various controversies regarding quantum-mechanical derivations of the oscillation formula, as well as the different field-theoretical approaches proposed to settle them. We then clear up the contradictions between the existing field-theoretical treatments by a thorough study of the external wave packet model. In particular, we show that the latter includes stationary models as a subcase. In addition, we explicitly compute decoherence terms, which destroy interferences, in order to prove that the coherence length can be increased without bound by more accurate energy measurements. We show that decoherence originates not only in the width and in the separation of wave packets, but also in their spreading through space-time. In this review, we neither assume the relativistic limit nor the stability of oscillating particles, so that the oscillation formula derived with field-theoretical methods can be applied not only to neutrinos but also to neutral K and B mesons. Finally, we discuss oscillations of correlated particles in the same framework.Comment: v2, 124 pages, 10 figures (7 more); updated review of the literature; complete derivation of the oscillation probability at short and large distance; more details on the influence of the spreading of the amplitude on decoherence; submitted to Physics Report

Dissipative Chaos in Semiconductor Superlattices

We consider the motion of ballistic electrons in a miniband of a semiconductor superlattice (SSL) under the influence of an external, time-periodic electric field. We use the semi-classical balance-equation approach which incorporates elastic and inelastic scattering (as dissipation) and the self-consistent field generated by the electron motion. The coupling of electrons in the miniband to the self-consistent field produces a cooperative nonlinear oscillatory mode which, when interacting with the oscillatory external field and the intrinsic Bloch-type oscillatory mode, can lead to complicated dynamics, including dissipative chaos. For a range of values of the dissipation parameters we determine the regions in the amplitude-frequency plane of the external field in which chaos can occur. Our results suggest that for terahertz external fields of the amplitudes achieved by present-day free electron lasers, chaos may be observable in SSLs. We clarify the nature of this novel nonlinear dynamics in the superlattice-external field system by exploring analogies to the Dicke model of an ensemble of two-level atoms coupled with a resonant cavity field and to Josephson junctions.Comment: 33 pages, 8 figure

Measurement of the Neutron Radius of 208Pb Through Parity-Violation in Electron Scattering

We report the first measurement of the parity-violating asymmetry A_PV in the elastic scattering of polarized electrons from 208Pb. A_PV is sensitive to the radius of the neutron distribution (Rn). The result A_PV = 0.656 \pm 0.060 (stat) \pm 0.014 (syst) ppm corresponds to a difference between the radii of the neutron and proton distributions Rn - Rp = 0.33 +0.16 -0.18 fm and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.Comment: 6 pages, 1 figur
