This article provides recommendations from the National Multiple Sclerosis Society's Clinical Outcomes Assessment Task Force. The Task Force was appointed in 1994 and charged with recommendending improved approaches for clinical outcomes assessment in future controlled clinical trials. The recommendations herein follow extensive deliberation and data(More)
Data driven POS tagging has achieved good performance for English, but can still lag behind linguistic rule based taggers for morphologically complex languages, such as Icelandic. We extend a statistical tagger to handle fine grained tagsets and improve over the best Icelandic POS tagger. Additionally, we develop a case tagger for non-local case and gender(More)
This article represents initial deliberation of an international task force appointed by the US National Multiple Sclerosis Society to develop recommendations for optimal clinical assessment tools for multiple sclerosis clinical trials. Presented within this article are the key issues identified by the task force during its initial year of deliberation.(More)
A pilot study was undertaken to test the safety and establish the side effect profile of recombinant human interferon-beta 1b (Betaseron, Berlex Laboratories, Richmond, CA), in patients with relapsing-remitting multiple sclerosis (RRMS). During the initial dose finding period (24 weeks), five groups of 6 patients each were treated by subcutaneous injection(More)
BACKGROUND Prognosis for the majority of children with brain stem gliomas is dismal. In previous studies, recombinant beta-interferon (r beta IF) has been shown to be effective for children with recurrent brain stem gliomas and may also act synergistically with radiotherapy (RT). METHODS Thirty-two children with diffuse intrinsic brain stem gliomas were(More)
We describe the background for and building of IcePaHC, a one million word parsed historical corpus of Icelandic which has just been finished. This corpus which is completely free and open contains fragments of 60 texts ranging from the late 12 century to the present. We describe the text selection and text collecting process and discuss the quality of the(More)

The detailed quantitative study of language change, as found in studies such as Labov (1994) and Kroch (1989), has raised two central questions for linguistic theory. The first is an issue in the theory of language change itself, namely: do changes in different components of the grammar progress in the same way? The second question addresses the(More)
This paper investigates the relationship between organizational effects of pre-natal testosterone and the use of "tomboy" as a descriptor for young women. We show in a sample of 44 women that a woman's right hand 2D:4D ratio is a significant predictor of whether they will be labeled as a "tomboy", with a decrease in 2D:4D ratio corresponding to an increase(More)
