    Aboriginal and Torres Strait Islander peoples continue to be pathologised in medical curriculum, leaving graduates feeling unequipped to effectively work cross-culturally. These factors create barriers to culturally safe health care for Aboriginal and Torres Strait Islander peoples. In this pilot pre-post study, we followed the learning experiences of 7 medical students and 4 medical registrars undertaking clinical placements at an urban Aboriginal and Torres Strait Islander primary health care service in 2014. Through analysis and comparison of pre- and post-placement responses to a paper-based case study of a fictitious Aboriginal patient, we identified four learning principles for medical professionalism: student exposure to nuanced, complex and positive representations of Aboriginal peoples; positive practitioner role modelling; interpersonal skills that build trust and minimise patient-practitioner relational power imbalances; and, knowledge, understanding and skills for providing patient centred, holistic care. Though not exhaustive, these principles can increase the capacity of practitioners to foster culturally safe and optimal health care for Aboriginal peoples. Furthermore, competence and effectiveness in Aboriginal health contexts is an essential component of medical professionalism

    QCD Predictions for the Transverse Energy Flow in Deep-Inelastic Scattering in the Small x HERA Regime

    Full text link
    The distribution of transverse energy, ETE_T, which accompanies deep-inelastic electron-proton scattering at small xx, is predicted in the central region away from the current jet and proton remnants. We use BFKL dynamics, which arises from the summation of multiple gluon emissions at small xx, to derive an analytic expression for the ETE_T flow. One interesting feature is an xϵx^{-\epsilon} increase of the ETE_T distribution with decreasing xx, where ϵ=(3αs/π)2log2\epsilon = (3\alpha_s/\pi)2\log 2. We perform a numerical study to examine the possibility of using characteristics of the ETE_T distribution as a means of identifying BFKL dynamics at HERA.Comment: 16 pages, REVTEX 3.0, no figures.

    Les villages tanzaniens ujamaa 40 ans plus tard : Moralisation et commémoration du collectivisme

    Entre 1967 et 1977, quelque 10 millions de Tanzaniens ont été déplacés de leur terre affermée et regroupés dans des villages ujamaa (littéralement, familyhood) bâtis par suite d’une décision gouvernementale, donnant lieu ainsi à l’un des plus vastes programmes de réinstallation de l’histoire. Le président Julius Nyerere, « père » et philosophe du socialisme tanzanien, a justifié la villagisation en alléguant qu’elle permettrait d’améliorer la prestation de services de base à la population, tels que des cliniques médicales, des écoles et de l’eau potable. Or, dans la foulée de l’abandon progressif du programme et du discours socialistes au milieu des années 1980, le sort de ces villages demeure dans une large mesure inconnu. Comment les villageois évaluent-ils de nos jours la vie dans ces villages comparativement à ce qu’elle était à l’époque socialiste? Quels éléments de la coopération communale, s’il s’avère que celle‑ci a véritablement existé, ont été maintenus? Cet article fait état d’une enquête réalisée auprès de résidants d’anciens villages ujamaa de la région de Mwanza. Leurs témoignages apportent certaines réponses à ces questions et sont mis en contexte dans une plus vaste analyse de la politique agricole tanzanienne sous les régimes socialiste et postsocialiste.Between 1967 and 1977, some 10 million Tanzanians were moved from scattered individual holdings into government mandated Ujamaa (literally, ‘familyhood’) villages in one of the largest resettlement movements in history. President Julius Nyerere, ‘father’ and philosopher of Tanzanian socialism, justified villagization on the grounds of being better able to provide basic services, such as medical clinics, schools, and clean water, to the citizenry. Yet in the wake of the quiet abandonment of socialist policy and rhetoric in the mid-1980s, the fate of these villages remains largely unknown. How do villagers evaluate life in these villages now as compared to socialist times? Have any elements of communal cooperation that may have existed been retained? In this paper, interviewed with residents in former Ujamaa villages in Mwanza Region provide some answers to these questions and are contextualized within a broader analysis of agricultural policy in socialist and postsocialist Tanzania.Entre 1967 y 1977, cerca de 10 millones de tanzano fueron desplazados de las tierras que rentaban y reagrupados en pueblos ujamaa (literalmente, lotes familiares) construidos por designio gubernamental, justificando así uno de los más vastos programas de re-localización de la historia. El presidente Julios Nyerere «padre» y filósofo del socialismo tanzano, había justificado la creación de esos pueblos argumentando que eso permitiría mejorar la prestación de servicios de base a la población, tal y como las clínicas médicas, las escuelas y el agua potable. Ahora bien, con el abandono progresivo del programa y del discurso socialista a mediados de los años 1980, aun se ignora cual será el destino de dichos pueblos. ¿Cómo sus habitantes evalúan actualmente la vida en esos pueblos comparada con lo que vivían durante la época socialista? ¿Cuáles son los elementos de la cooperación comunal, si realmente existió, que han perdurado? Este artículo reporta una investigación realizada entre los residentes de los antiguos pueblos ujamaa de la región de Mwanza. Sus afirmaciones permiten dilucidar ciertas cuestiones y han sido contextualizadas en el cuadro de un análisis más vasto de la política agrícola tanzana bajo los regímenes socialistas y post-socialistas

    BFKL versus HERA

    Get PDF
    The BFKL equation and the kT-factorization theorem are used to obtain predictions for F2 in the small Bjorken-x region over a wide range of Q**2. The dependence on the parameters, especially on those concerning the infrared region, is discussed. After a background fit to recent experimental data obtained at HERA and at Fermilab (E665 experiment), we find that the predicted, almost Q**2 independent BFKL slope lambda >= 0.5 appears to be too steep at lower Q**2 values. Thus there seems to be a chance that future HERA data can distinguish between pure BFKL and conventional field theoretic renormalization group approaches.Comment: 26 pages, 6 eps figures, LaTeX2e using epsfig.sty and amssymb.st

    Constraints on gluon evolution at small x

    Get PDF
    The BFKL and the unified angular-ordered equations are solved to determine the gluon distribution at small xx. The impact of kinematic constraints is investigated. Predictions are made for observables sensitive to the gluon at small xx. In particular comparison is made with measurements at the HERA electron-proton collider of the proton structure function F2(x,Q2)F_2 (x, Q^2) as a function of lnQ2\ln Q^2, the charm component, F2c(x,Q2)F_2^c(x,Q^2) and diffractive J/ψJ/\psi photoproduction.Comment: 17 LaTeX pages and 9 postscript figure

    Unitarization of Structure Functions at Large 1/x{\bf 1/x}

    Full text link
    We discuss the effects of the ss-channel unitarization on the xx and Q2Q^{2} dependence of structure functions. The unitarization is implemented at the level of photoabsorption cross sections by resorting to the light--cone wave functions of virtual photons and to the diagonalization property of the scattering matrix in a basis of Fock states of the photon with fixed transverse size. Triple pomeron effects are also explicitly taken into account. We find large unitarity corrections to the structure functions at x<102x < 10^{-2}. The results are in very good agreement with the existing NMC and the preliminary HERA data.Comment: 12 page

    A unified BFKL and GLAP description of F2F_2 data

    Full text link
    We argue that the use of the universal unintegrated gluon distribution and the kTk_T (or high energy) factorization theorem provides the natural framework for describing observables at small x. We introduce a coupled pair of evolution equations for the unintegrated gluon distribution and the sea quark distribution which incorporate both the resummed leading ln(1/x)ln (1/x) BFKL contributions and the resummed leading ln(Q2)ln (Q^2) GLAP contributions. We solve these unified equations in the perturbative QCD domain using simple parametic forms of the nonperturbative part of the integrated distributions. With only two (physically motivated) input parameters we find that this kTk_T factorization approach gives an excellent description of the measurements of F2(x,Q2)F_2 (x,Q^2) at HERA. In this way the unified evolution equations allow us to determine the gluon and sea quark distributions and, moreover, to see the x domain where the resummed ln(1/x)ln (1/x) effects become significant. We use kTk_T factorization to predict the longitudinal structure function FL(x,Q2)F_L (x,Q^2) and the charm component of F2(x,Q2)F_2 (x,Q^2).Comment: 25 pages, LaTeX, 9 figure

    Unintegrated gluon distributions and Higgs boson production in proton-proton collisions

    Full text link
    Inclusive cross sections for Higgs boson production in proton-proton collisions are calculated in the formalism of unintegrated gluon distributions (UGDF). Different UGDF from the literature are used. Although they were constructed in order to describe the HERA deep-inelastic scattering F2F_2 data, they lead to surprisingly different results for Higgs production. We present both two-dimensional invariant cross section as a function of Higgs rapidity and transverse momentum, as well as corresponding projections on rapidity or transverse momentum. We quantify the differences between different UGD's by applying different cuts on interrelations between transverse momentum of Higgs and transverse momenta of both fusing gluons. We focus on large rapidity region. The interplay of the gluon-gluon fusion and weak-boson fusion in rapidity and transverse momentum is discussed. We find that above pTp_T \sim 50-100 GeV the weak-gauge-boson fusion dominates over gluon-gluon fusion.Comment: 32 pages, 18 figures, corrected version, restructured, misprints removed, discussion added, new figure added, in print in EPJ
