âWe kind of try to merge our own experience with the objectivity of the criteriaâ: The role of connoisseurship and tacit practice in undergraduate fine art assessment
This article explores connoisseurship in the context of fine art undergraduate assessment practice. I interviewed twelve fine art lecturers in order to explore and unpack
the concept of connoisseurship in relation to subjectivity, objectivity and tacit practice.
Building on the work of Bourdieu (1973, 1977, 1986) and Shay (2003, 2005), both of whom problematize the view that subjectivity and objectivity are binary opposites, my
research illustrates the ways that connoisseurship is underpinned by informed professional judgements located in communities of practice. Within this particular conception
of connoisseurship, the lecturersâ expertise is co-constituted in communities of assessors through participation and engagement. Standards reside in communities of practice
QCD: Challenges for the Future
Despite many experimental verifications of the correctness of our basic
understanding of QCD, there remain numerous open questions in strong
interaction physics and we focus on the role of future colliders in addressing
these questions. We discuss possible advances in the measurement of ,
in the study of parton distribution functions, and in the understanding of low
physics at present colliders and potential new facilities. We also touch
briefly on the role of spin physics in advancing our understanding of QCD.Comment: 12 pages, LATEX2e with snow2e, epsfig and 2 figures. Also available

Improved Measurement of ttZ Couplings at the LHC
We consider QCD tt~Z production at the LHC with Z->\bar\nu\nu and
all-hadronic tt~ decays, i.e. pp -> p_T(miss)bb~+4 jets, as a tool to measure
ttZ couplings. This channel has a significantly larger cross section than those
where the Z boson decays leptonically. However, tt~, bb~+4 jet, tt~j and tt~jj
production give rise to potentially large backgrounds. We show that these
processes can be suppressed to an acceptable level with suitable cuts, and find
that adding the p_T(miss)bb~+4 jet channel to the final states used in previous
ttZ couplings analyses will improve the sensitivity by 10-60%. We also discuss
how the measurement of the ttZ couplings may constrain Little Higgs models.Comment: revtex4, 16 pages, 4 figures, 1 tabl
