Perceptions of the effectiveness of a global diversity network.

“The motivation is that it is at the heart of our work. It’s what matters more than anything, you know, I think EO&D principles, if we get those values, you know, our core values right, as an organisation, if we walk the talk in a sense in all of this, then everything else falls out of it as a consequence. We will build relationships, we will build the right projects, we’ll deliver impact, we’ll scale up, we’ll bring in the income, you know if I get that right. So what motivates me is the feeling that this is the most important thing. The irony is it doesn’t feel like that often, it feels like it’s a kind of added on organisationally. I’m not convinced the organisation sees EO&D that way, but that’s what motivates me. Actually believing, believing in the core values.” GDN Representative N1. The research takes place in the British Council which is the UK’s principal cultural relations organisation and a non departmental public body with offices in 110 countries. The British Council has its headquarters in London, where the researcher is based and in 2009 it marked its 75th anniversary. It therefore has a long history and wide international network. Consistent with the British Council's cultural relations role which concerns itself with building trust and understanding between the UK and other countries, matters of equality and diversity are an important aspect of not only its public face and activities, but its internal workings too. Its geographical spread and consequent diversity raise challenges however. A key challenge with wider resonances, confirmed by the Literature Review, is how to achieve the coherence and cohesion necessary for a shared, organisational identity and an appropriate and viable joined up approach to equality and diversity, whilst also respecting, valuing and managing diversity and cultural difference. In response, the British Council has, amongst other things, established a Global Diversity Network (GDN) of regional representatives who are deemed to be an important resource in this process. However the Diversity Unit which leads and manages the British Council’s equality and diversity agenda and the Global Diversity Network, believe that the Network is not as effective as it could be and the reasons why this is the case need to be explored. As a result the research has focused on the members. In doing so it has interrogated how they perceive they fulfil their role, the difficulties they face, their learning and development needs and explored in greater depth the perceptions of a contrasting group of strong and weak performers. The perceptions and evaluation of wider stakeholders are also incorporated. The ultimate aim, through a case study and action research approach, is to improve the GDN’s effectiveness. What emerges challenges the alleged research problem and highlights a number of things not previously known or considered. This includes the finding that the Network is perceived by its members and its stakeholders as effective but under resourced and there are gaps in how it has been managed and supported by the Diversity Unit. In addition, the research surfaced the existence of 'ideal' GDN members and no concerns of significance about the relevance of equality and diversity within the British Council's varying operating environments. A number of recommendations which are intended to support the GDN to be more effective ,and thereby alleviate pressure on the Diversity Unit, as well as contribute to improved, sustainable organisational performance, are proposed. A key recommendation relates to additional resources and addressing the learning and development needs of GDN members by making use of and building on the British Council’s Diversity Assessment Framework; this being the potent tool that supports and measures efforts to mainstream equality and diversity organisation wide. Recommendations are at various stages of implementation with some that await Executive Board endorsement. Dissemination of the research findings will take place internally and externally and internationally. This is in order to add to the limited body of knowledge about the approaches global organisations adopt in managing equality and diversity, revealed both by the Literature Review and the experiences of the Diversity Unit

Diffractive jet production in a simple model with applications to HERA

In diffractive jet production, two high energy hadrons A and B collide and produce high transverse momentum jets, while hadron A is diffractively scattered. Ingelman and Schlein predicted this phenomenon. In their model, part of the longitudinal momentum transferred from hadron A is delivered to the jet system, part is lost. Lossless diffractive jet production, in which all of this longitudinal momentum is delivered to the jet system, has been discussed by Collins, Frankfurt, and Strikman. We study the structure of lossless diffractive jet production in a simple model. The model suggests that the phenomenon can be probed experimentally at HERA, with A being a proton and B being a bremsstrahlung photon with virtuality $Q^2$. Lossless events should be present for small $Q^2$, but not for $Q^2$ larger than $1/R_{\rm P}^2$, where $R_{\rm P}$ is a characteristic size of the pomeron.Comment: 23 pages, REVTeX 3.0 with 8 postscript figures compressed with uufiles, OITS 536 and AZPH-TH/94-0

Two parton shower background for associate W Higgs production

The estimates of the background for the associate W Higgs production, which stems from the two parton shower production. It is about 1 - 2.5 times larger than the signal. However, this background does not depend on the rapidity difference between the W and the $b \bar{b}$ pair, while the signal peaks when the rapidity difference is zero. The detailed calculations for the enhanced diagrams' contribution to this process, are presented, and it is shown that the overlapping singularities, being important theoretically, lead to a negligible contribution for the LHC range of energiesComment: 35 pages and 10 figures in eps file

Spin dependent structure function g_1 at low x and low Q^2

Theoretical description of the spin dependent structure function g_1(x,Q^2) in the region of low values of x and Q^2 is presented. It contains the Vector Meson Dominance contribution and the QCD improved parton model suitably extended to the low Q^2 domain. Theoretical predictions are compared with the recent experimental data in the low x, low Q^2 region

Hard scattering factorization and light cone hamiltonian approach to diffractive processes

We describe diffractive deeply inelastic scattering in terms of diffractive parton distributions. We investigate these distributions in a hamiltonian formulation that emphasizes the spacetime picture of diffraction scattering. For hadronic systems with small transverse size, diffraction occurs predominantly at short distances and the diffractive parton distributions can be studied by perturbative methods. For realistic, large-size systems we discuss the possibility that diffractive parton distributions are controlled essentially by semihard physics at a scale of nonperturbative origin of the order of a GeV. We find that this possibility accounts for two important qualitative aspects of the diffractive data from HERA: the flat behavior in beta and the delay in the fall-off with Q^2.Comment: 51 pages, 16 figure

High-Energy Factorization and Small-X Deep Inelastic Scattering Beyond Leading Order

High-energy factorization in QCD is investigated beyond leading order and its relationship to the factorization theorem of mass singularities is established to any collinear accuracy. Flavour non-singlet observables are shown to be regular at small x order by order in perturbation theory. In the singlet sector, we derive the relevant master equations for the space-like evolution of gluons and quarks. Their solution enables us to sum next-to-leading corrections to the small-x behaviour of quark anomalous dimensions and deep inelastic scattering coefficient functions. We present results in both MSbar and DIS factorization schemes.Comment: 46 pages (+ 7 figures not included, available from the authors), Latex, Cavendish-HEP-94/0

DVCS amplitude at tree level: Transversality, twist-3, and factorization

We study the virtual Compton amplitude in the generalized Bjorken region (q^2 -> Infinity, t small) in QCD by means of a light-cone expansion of the product of e.m. currents in string operators in coordinate space. Electromagnetic gauge invariance (transversality) is maintained by including in addition to the twist-2 operators 'kinematical' twist-3 operators which appear as total derivatives of twist-2 operators. The non-forward matrix elements of the elementary twist-2 operators are parametrized in terms of two-variable spectral functions (double distributions), from which twist-2 and 3 skewed distributions are obtained through reduction formulas. Our approach is equivalent to a Wandzura-Wilczek type approximation for the twist-3 skewed distributions. The resulting Compton amplitude is manifestly transverse up to terms of order t/q^2. We find that in this approximation the tensor amplitude for longitudinal polarization of the virtual photon is finite, while the one for transverse polarization contains a divergence already at tree level. However, this divergence has zero projection on the polarization vector of the final photon, so that the physical helicity amplitudes are finite.Comment: 34 pages, revtex, 1 eps figure included using epsf.

Central Exclusive Production in QCD

We investigate the theoretical description of the central exclusive production process, h1+h2 -> h1+X+h2. Taking Higgs production as an example, we sum logarithmically enhanced corrections appearing in the perturbation series to all orders in the strong coupling. Our results agree with those originally presented by Khoze, Martin and Ryskin except that the scale appearing in the Sudakov factor, mu=0.62 \sqrt{\hat{s}}, should be replaced with mu=\sqrt{\hat{s}}, where \sqrt{\hat{s}} is the invariant mass of the centrally produced system. We confirm this result using a fixed-order calculation and show that the replacement leads to approximately a factor 2 suppression in the cross-section for central system masses in the range 100-500 GeV.Comment: 41 pages, 19 figures; minor typos fixed; version published in JHE

Multiparton interactions and production of minijets in high energy hadronic collisions

We discuss the inclusive cross section to produce two minijets with a large separation in rapidity in high energy hadronic collisions. The contribution to the inclusive cross section from the exchange of a BFKL Pomeron is compared with the contribution from the exchange of two BFKL Pomerons, which is induced by the unitarization of the semi-hard interaction. The effect of the multiple exchange is studied both as a function of the azimuthal correlation and as a function of the transverse momentum of the observed minijets.Comment: TeX file, 20 pages, 4 figures available on reques

Different behaviour of the spin structure functions g1(x)g_1(x) and h1(x)h_1(x) at x→0x\to 0

We consider low-$x$ behaviour of the spin structure functions $g_1(x)$ and $h_1(x)$ in the unitarized chiral quark model which combines ideas on the constituent quark structure of hadrons with a geometrical scattering picture and unitarity. A nondiffractive singular low-$x$ dependence of $g^p_1(x)$ and $g_1^n(x)$ indicated by the recent SMC experimental data is described. A diffractive type smooth behaviour of $h_1(x)$ is predicted at small $x$. The expectations for the double-spin asymmetries in the low-mass Drell-Yan production at RHIC in the central region are discussed alongside.Comment: LaTeX, 10 pages, 2 figure
