Différenciation genre du champ littéraire et valeur positionnelle du ré-investissment générique: l'exemple de "Quatrième version" de Luisa Valenzuela

Dans les productions littéraires des autrices qui questionnent les contraintes et les limites qui pèsent sur l’accès et la pratique du discours littéraire des femmes, la gestion de « l’investissement générique » apparaît comme un véritable marqueur de positionnement. Le positionnement des femmes en littérature est en effet inextricablement lié au questionnement du « genre des genres » qui a historiquement construit une frontière ritualisée et hiérarchique entre les genres dits féminins et masculins et ainsi servi le cantonnement des autrices à un territoire discursif minoré. L’interrogation des modalités sexuées de l’investissement générique dans la nouvelle « Cuarta versión » de Luisa Valenzuela, à laquelle nous procédons dans cet article, nous conduit à explorer les enjeux positionnels de la réappropriation des genres dits féminins, comme le journal intime ou l’épistolaire. Cette analyse des relations entre genres littéraires et rapports de genre a pour ambition première de porter au jour la tension qui caractérise la construction du positionnement générique des femmes, confrontées au « dilemme de la différence ». Les remaniements génériques que nous envisageons sont en effet pris dans une oscillation qui conjugue le jeu avec, d’une part, la revalorisation du féminin et, de l’autre, la déstabilisation des frontières entre les genres sexuels et textuels. L’on pose ainsi dans cet article l’hypothèse de l’existence d’un positionnement générique « impur », qui malmène systématiquement l’opposition masculin/féminin sans qu’elle soit pour autant dépassée dans sa dimension systémique, pour explorer les tensions à l’oeuvre dans le processus de légitimation de la production des femmes dans le champ littéraire

Precision luminosity measurement at LHC using two-photon production of mu^+ mu^- pairs

The application of the two-photon process pp -> pp + mu^+mu^- for the luminosity measurements at LHC with the ATLAS detector is considered. The expected accuracy of the absolute offline luminosity determination is 1 - 2 % for the luminosity range of 10^{33} - 10^{34} cm^-2 s^-1. The preliminary cross section estimates done for LHCb promise the same level of the luminosity measurement accuracy at L = 2 x 10^{32} cm^-2 s^-1.Comment: 10 pages, Latex, 5 figures (9 .eps files).

Manifestly Covariant Analysis of the QED Compton Process in ep→eγpe p\to e \gamma p and ep→eγXe p \to e \gamma X

We calculate the unpolarized QED Compton scattering cross section in a manifestly covariant way. Our approach allows a direct implementation of the specific kinematical cuts imposed in the experiments, {\it e. g.} HERA-H1. We compare the 'exact' cross section in terms of the structure functions $F_{1,2} (x_B,Q^2)$, assuming the Callan-Gross relation, with the one obtained using the equivalent photon approximation (EPA) as well as with the experimental results. We find that the agreement with the EPA is better in $x_{\gamma}$ bins, where $x_{\gamma}$ is the fraction of the longitudinal momentum of the proton carried by the virtual photon, compared to the bins in the leptonic variable $x_l$.Comment: 22 pages, 4 figures, 2 table

States of nomadism, conditions of diaspora : studies in writing between South Africa and the United States, 1913-1936.

Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.Using the theoretical idea of ‘writing between’ to describe the condition of the travelling subject, this study attempts to chart some of the literary, intellectual and cultural connections that exist(ed) between black South African intellectuals and writers, and the experiences of their African- American counterparts in their common movements towards civil liberty, enfranchisement and valorised consciousness. The years 1913-1936 saw important historical events taking place in the United States, South Africa and the world – and their effects on the peoples of the African diaspora were signficant. Such events elicited unified black diasporic responses to colonial hegemony. Using theories of transatlantic/transnational cultural negotiation as a starting point, conceptualisations that map out, and give context to, the connections between transcontinental black experiences of slavery and subjugation, this study seeks to re-envisage such black South African and African-American intellectual discourses through reading them anew. These texts have been re-covered and re-situated, are both published and unpublished, and engage the notion of travel and the instability of transatlantic voyaging in the liminal state of ‘writing between’. With my particular regional focus, I explore the cultural and intellectual politics of these diasporic interrelations in the form of case studies of texts from several genres, including fiction and autobiography. They are: the travel writings of Xhosa intellectual, DDT Jabavu, with a focus on his 1913 journey to the United States; an analysis of Ethelreda Lewis’s novel, Wild Deer (1933), which imagines the visit of an African-American musician, Paul Robeson-like figure to South Africa; and Eslanda Goode Robeson’s representation of her African Journey (1945) to the country in 1936, and the traveller’s gaze as expressed through the ethnographic imagination, or the anthropological ‘eye’ in the text

The DVCS Measurement at HERA

Accessing the Longitudinally Polarized Photon Content of the Proton

We investigate the QED Compton process (QEDCS) in longitudinally polarized lepton-proton scattering both in the elastic and inelastic channels and show that the cross section can be expressed in terms of the polarized equivalent photon distribution of the proton. We provide the necessary kinematical constraints to extract the polarized photon content of the proton using this process at HERMES, COMPASS and eRHIC. We also discuss the suppression of the major background process coming from virtual Compton scattering. We point out that such an experiment can give valuable information on $g_1(x_B, Q^2)$ in the small $x_B$, broad $Q^2$ region at the future polarized collider eRHIC and especially in the lower $Q^2$, medium $x_B$ region in fixed target experiments.Comment: Version to appear in PR

O(\alpha^2 L) Radiative Corrections to Deep Inelastic ep Scattering

The leptonic QED radiative corrections are calculated in the next-to-leading log approximation ${\cal O}[\alpha^2 \ln(Q^2/m_e^2)]$ for unpolarized deeply inelastic $ep$--scattering in the case of mixed variables. The corrections are determined using mass factorization in the OMS--scheme for the double--differential scattering cross sections.Comment: 10 pages LATEX, 1 style file
