EN CARNE PROPIA: EMBODIED IDENTITIES IN CUBAN AND MEXICAN CULTURAL PRODUCTION

In twentieth-century Cuba and Mexico, each post-revolutionary state consolidated power through cultural production, especially film and literature, by funding national cinema and institutions such as the Union of Cuban Writers and Artists. This project examines the ways in which contemporary writers, filmmakers, and performance artists (1980-2006) emphasize personal, embodied experience to examine and frequently contest the generalized and overarching identity constructs propagated as part of an explicitly national post-revolutionary culture in Cuba and Mexico. Writers such as Ena Lucía Portela, Abilio Estévez, Pedro Juan Gutiérrez, Antonio José Ponte, Jorge Volpi, Federico Campbell, performance artist Astrid Hadad, and filmmakers Tommy Lee Jones, Tomás Gutiérrez Alea, and Alfonso Cuarón explore how the destabilization of revolutionary ideology and increasing economic and political changes in each country affects the daily lives of artistic subjects, thereby underscoring the social role of art and the tensions between art and commerce in contemporary Cuba and Mexico

Charge Asymmetry in 1-1000 GeV Electromagnetic Showers and Possibility of Its Measurementnt

For the high energy electromagnetic showers the thickness dependence of a) the development of electron and positron components, b) the difference between the secondary electron and positron numbers, c) the charge asymmetry of high energy electromagnetic showers, as well as d) the spectral distributions of the components at the shower maxima for various energies of primary particle energies,1 - 1000 GeV were investigated employing GEANT Monte Carlo simulation package. Using these simulation results it is discussed the possibility of observation and study of the charge asymmetry with the help of a magnetic spectrometer which is important for the current and future experiments on the detection of radiowaves produced by high energy neutrinos.Comment: TEX file and 4 figure

A measurement of the pion radius

We propose a wire spark chamber experiment to measure the pion electromagnetic radius accurate to {+-}0.03f by measuring the scattering cross section for 50-80 GeV pions from electrons in a liquid hydrogen target. The data will distinguish between the {rho} dominance prediction of 0.64f and the ''proton-like'' radius to 0.81f

Neutron charge form factor at large q2q^2

The neutron charge form factor $G_{En}(q)$ is determined from an analysis of the deuteron quadrupole form factor $F_{C2}$ data. Recent calculations, based on a variety of different model interactions and currents, indicate that the contributions associated with the uncertain two-body operators of shorter range are relatively small for $F_{C2}$, even at large momentum transfer $q$. Hence, $G_{En}(q)$ can be extracted from $F_{C2}$ at large $q^2$ without undue systematic uncertainties from theory.Comment: 8 pages, 3 figure

Photon asymmetry measurements of γ→ p→ π0p for Eγ= 320-650 MeV

High-statistics measurements of the photon asymmetry Σ for the γ→ p→ π0p reaction have been made in the center-of-mass energy range W= 1214 - 1450 MeV. The data were measured with the MAMI A2 real photon beam and Crystal Ball/TAPS detector systems in Mainz, Germany. The results significantly improve the existing world data and are shown to be in good agreement with previous measurements, and with the MAID, SAID, and Bonn-Gatchina predictions. We have also combined the photon asymmetry results with recent cross-section measurements from Mainz to calculate the profile functions, Σˇ (= σ0Σ) , and perform a moment analysis. Comparison with calculations from the Bonn-Gatchina model shows that the precision of the data is good enough to further constrain the higher partial waves, and there is an indication of interference between the very small F-waves and the N(1520) 3 / 2 - and N(1535) 1 / 2 - resonances
