ence in the productivity of the vegetation on the control plots. Odum et al. (2) observed comparable differences in productivity during old field succession, but these were attributable to previous fertilization and changes in the growth forms of the dominants, factors not adequately discussed by Hurd et al. We have also observed significant differences in the primary production of herbaceous c...
متن کاملHPS: High precision stemmer
Research into unsupervised ways of stemming has resulted, in the past few years, in the development of methods that are reliable and perform well. Our approach further shifts the boundaries of the state of the art by providing more accurate stemming results. The idea of the approach consists in building a stemmer in two stages. In the first stage, a stemming algorithm based upon clustering, whi...
متن کاملHigh Precision Spectrometers – HPS Project
The aim of this note is to inform the CMS Management about the status of the FP420 R&D project. Since autumn 2008 there has been significant progress on most of the issues raised by the CMS FP420 Review Panel. We also bring to the attention of the Management a new proposal to instrument the region at about 240 m from IP5, as well as our plans about a staged installation. Because of the 240 m ex...
متن کاملThe Kuhnian mode of HPS
In this article I argue that a methodological challenge to an integrated history and philosophy of science approach put forth by Ronald Giere almost forty years ago can be met by what I call the Kuhnian mode of History and Philosophy of Science (HPS). Although in the Kuhnian mode of HPS norms about science are motivated by historical facts about scientific practice, the justifiers of the constr...
متن کاملPhotoperiod, early post-natal eye growth, and visual deprivation
(1) We studied the influence of photoperiod and unilateral lid suture on post-natal ocular growth in two types of White Leghorn chicks previously reported to respond differently to visual deprivation, Truslow and Cornell K chicks. We analyzed the chicks after 2 weeks of rearing, a time period commonly used in neuropharmacological studies of eye growth but much shorter than in most prior studies...
