D* Production in Deep Inelastic Scattering at HERA
This paper presents measurements of D^{*\pm} production in deep inelastic
scattering from collisions between 27.5 GeV positrons and 820 GeV protons. The
data have been taken with the ZEUS detector at HERA. The decay channel
(+ c.c.) has been used in the study. The
cross section for inclusive D^{*\pm} production with
and is 5.3 \pms 1.0 \pms 0.8 nb in the kinematic region
{ GeV and }. Differential cross
sections as functions of p_T(D^{*\pm}), and are
compared with next-to-leading order QCD calculations based on the photon-gluon
fusion production mechanism. After an extrapolation of the cross section to the
full kinematic region in p_T(D^{*\pm}) and (D^{*\pm}), the charm
contribution to the proton structure function is
determined for Bjorken between 2 10 and 5 10.Comment: 17 pages including 4 figure
Observation of Scaling Violations in Scaled Momentum Distributions at HERA
Charged particle production has been measured in deep inelastic scattering
(DIS) events over a large range of and using the ZEUS detector. The
evolution of the scaled momentum, , with in the range 10 to 1280
, has been investigated in the current fragmentation region of the Breit
frame. The results show clear evidence, in a single experiment, for scaling
violations in scaled momenta as a function of .Comment: 21 pages including 4 figures, to be published in Physics Letters B.

Dancing in the Dark: The Relationship between Policy Research and Policy Making in Dutch Higher Education
The idea that research is directly useful in the policy process has been widely disputed,2 and much has been written about the differences between the contexts or “cultures” in which research is produced and in which policy is made.3 A number of authors, however, have pointed out indirect ways in which policy makers may make use of research findings or have tried to find more complex ways of understanding and describing the relationships between researchers and policy makers.4 It has been proposed, for example, that the categories of researcher and policy maker are not always mutually exclusive and that interactions between all actors involved in this process could be better described as two-way, rather than only as one-way, interactions.
