Comparing Quark Jets in e+e- and DIS

I discuss event cuts in DIS which improve the similarity between the current Breit hemisphere and hemispheres in $e^+e^-$ annihilation. I also present a method to study the scale evolution in quark hemispheres using data from fixed energy $e^+e^-$ experiments. This method can benefit from the high statistics and flavour tagging at LEP1, also at scales relevant for a comparison with HERA results.
