We provide an assessment of the impact of parton distributions on the determination of LHC processes, and of the accuracy with which parton distributions (PDFs) can be extracted from data, in particular from current and forthcoming HERA experiments. We give an overview of reference LHC processes and their associated PDF uncertainties, and study in detail W and Z production at the LHC. We discuss the precision which may be obtained from the analysis of existing HERA data, tests of consistency of HERA data from different experiments, and the combination of these data. We determine further improvements on PDFs which may be obtained from future HERA data (including measurements of F{sub L}), and from combining present and future HERA data with present and future hadron collider data. We review the current status of knowledge of higher (NNLO) QCD corrections to perturbative evolution and deep-inelastic scattering, and provide reference results for their impact on parton evolution, and we briefly examine non-perturbative models for parton distributions. We discuss the state-of-the art in global parton fits, we assess the impact on them of various kinds of data and of theoretical corrections, by providing benchmarks of Alekhin and MRST parton distributions and a CTEQ analysis of parton fit stability, and we briefly presents proposals for alternative approaches to parton fitting. We summarize the status of large and small x resummation, by providing estimates of the impact of large x resummation on parton fits, and a comparison of different approaches to small x resummation, for which we also discuss numerical techniques.

The Way of the Apprentice, defines the path of an apprentice to Jesus; one who is cooperating with God's ultimate plan for our lives rather than fighting against it. Becoming an apprentice is not about doing something, it's about becoming someone. RD first introduces the topic of being a Christian in modern times by discussing several examples of what readers may have seen as missing in their spiritual walks with God. From real life examples, he gives honest perspectives on how these issues could be uncovering the deeper roots to the problem. The "work" of a Christian, in God's eyes, is depicted in The Way of the Apprentice as first establishing the firm foundation of faith in Jesus, then moving into what God intended for all his chosen children; To be conformed into the image of Christ. RD unveils the internal changes within a person of God that must occur, and what struggles we all have that cause us to drift from God's plan for our lives. More importantly he shows with simple, time-tested Biblical principles how we can return to, then surpass the joy of our salvation...permanently.
