Différenciation genre du champ littéraire et valeur positionnelle du ré-investissment générique: l'exemple de "QuatriÚme version" de Luisa Valenzuela
Dans les productions littĂ©raires des autrices qui questionnent les contraintes et les limites qui pĂšsent sur lâaccĂšs et la pratique du discours littĂ©raire des femmes, la gestion de « lâinvestissement gĂ©nĂ©rique » apparaĂźt comme un vĂ©ritable marqueur de positionnement. Le positionnement des femmes en littĂ©rature est en effet inextricablement liĂ© au questionnement du « genre des genres » qui a historiquement construit une frontiĂšre ritualisĂ©e et hiĂ©rarchique entre les genres dits fĂ©minins et masculins et ainsi servi le cantonnement des autrices Ă un territoire discursif minorĂ©. Lâinterrogation des modalitĂ©s sexuĂ©es de lâinvestissement gĂ©nĂ©rique dans la nouvelle « Cuarta versiĂłn » de Luisa Valenzuela, Ă laquelle nous procĂ©dons dans cet article, nous conduit Ă explorer les enjeux positionnels de la rĂ©appropriation des genres dits fĂ©minins, comme le journal intime ou lâĂ©pistolaire. Cette analyse des relations entre genres littĂ©raires et rapports de genre a pour ambition premiĂšre de porter au jour la tension qui caractĂ©rise la construction du positionnement gĂ©nĂ©rique des femmes, confrontĂ©es au « dilemme de la diffĂ©rence ». Les remaniements gĂ©nĂ©riques que nous envisageons sont en effet pris dans une oscillation qui conjugue le jeu avec, dâune part, la revalorisation du fĂ©minin et, de lâautre, la dĂ©stabilisation des frontiĂšres entre les genres sexuels et textuels. Lâon pose ainsi dans cet article lâhypothĂšse de lâexistence dâun positionnement gĂ©nĂ©rique « impur », qui malmĂšne systĂ©matiquement lâopposition masculin/fĂ©minin sans quâelle soit pour autant dĂ©passĂ©e dans sa dimension systĂ©mique, pour explorer les tensions Ă lâoeuvre dans le processus de lĂ©gitimation de la production des femmes dans le champ littĂ©raire
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). Talk at the VIII Intern.

Manifestly Covariant Analysis of the QED Compton Process in and
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 , 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 bins, where
is the fraction of the longitudinal momentum of the proton carried
by the virtual photon, compared to the bins in the leptonic variable .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 âwriting betweenâ 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 â 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 âwriting betweenâ. 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 Lewisâs novel, Wild Deer (1933), which
imagines the visit of an African-American musician, Paul Robeson-like figure
to South Africa; and Eslanda Goode Robesonâs representation of her African
Journey (1945) to the country in 1936, and the travellerâs gaze as expressed
through the ethnographic imagination, or the anthropological âeyeâ in the text

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 in the
small , broad region at the future polarized collider eRHIC and
especially in the lower , medium region in fixed target experiments.Comment: Version to appear in PR

inelastic --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
