A new model for procuring e-books
This paper draws on a recent ground-breaking tender for e-books for higher education libraries in the UK. The strategy for the tender was informed by standard procurement practice and by the experience of acquiring other e-resources, particularly journals under the so-called big deal. Both are examined as background to the discussion of e-books in general and the tender in particular
Global Parton Distributions for the LHC Run II
We review the next generation global PDF sets: NNPDF3.0, MMHT14 and CT14. We
describe the global datasets, particularly the new data from LHC Run 1, recent
developments in QCD theory and PDF methodology, improvements in combination and
delivery, and future prospects for parton determination at Run 2.Comment: 15 pages, 11 figures; talk given at La Thuile, 3rd March 2015;

Momentum Conservation at Small x
We discuss how momentum conservation is implemented in perturbative
computations based on expansions of anomalous dimensions appropriate at small
. We show that for any given choice of coefficient functions there
always exists a factorization scheme where the gluon is defined in such a way
that momentum is conserved at next to leading order.Comment: 11 pages, plain TeX with harvma
Double Asymptotic Scaling '96
We review recent HERA data on the structure function F_2 at small x and large
Q^2. We show that the salient features of the data are revealed by comparing
them to the double asymptotic scaling behaviour which F_2 is predicted to
satisfy in perturbative QCD.Comment: 5 pages, LaTeX with espcrc2.sty (included), 11 figures included by

High Energy Resummation of Drell-Yan Processes
We present a computation of the inclusive Drell-Yan production cross-section
in perturbative QCD to all orders in the limit of high partonic centre-of-mass
energy. We compare our results to the fixed order NLO and NNLO results in MSbar
scheme, and provide predictions at NNNLO and beyond. Our expressions may be
used to obtain fully resummed results for the inclusive cross-section.Comment: 18 pages, 5 figures: version to be published in NP
Towards a business model for sustainable supply chain management
Designers make decisions that ultimately impact on both the economic, environmental and social performance of the products and process, and many of these costs and impacts occur across the supply chain. This paper aims to show initials elements of a research which aims to develop an integrated business model for sustainable supply chain management in order to facilitate the business management process in terms of assessment of suppliers and collaboration addressed to the sustainable improvements across supply chain. It is noteworthy that it is an imperative in the current competitive market that companies must be able to manage their entire production chain taking into account sustainable issues as an important factor in their decision processes. Therefore, it is believed that this model can integrate and strengthen a company’s functions and assist its decision processes as well as implement improvements within its supply chain
The Regularization of the Fermion Determinant in Chiral Quark Models
The momentum dependence of the quark self energy gives a physically motivated
and consistent regularization of both the real and imaginary parts of the quark
loop contribution to the meson action. We show that the amplitudes for
anomalous processes are always reproduced correctly.Comment: 12/8 pages (b/l), plain TeX with harvmac, SphT93/13
