The Korean Causative: A TAG Analysis

The Korean causative construction has been discussed for many years. This construction is of interest because it shows both monoclausal and biclausal properties, which are complicated by the case variation of the causee. In this paper I shall give a syntactic analysis of the causative within the Tree Adjoining Grammar (TAG hereafter) framework proposed by [Joshi, Levy & Takahashi 75], [Joshi 83] and [Kroch & Joshi 85]. This analysis captures both the syntactic biclausal and morphological monoclausal properties of the causative, and is well-attested from the comparative study with the Germanic verb-raising construction ([Kroch & Santorini 88]) and the Japanese causative construction ([Heycock 88])

Explaining the Color Distributions of Globular Cluster Systems in Elliptical Galaxies

The colors of globular clusters in most of large elliptical galaxies are bimodal. This is generally taken as evidence for the presence of two cluster subpopulations that have different geneses. However, here we find that, because of the non-linear nature of the metallicity-to-color transformation, a coeval group of old clusters with a unimodal metallicity spread can exhibit color bimodality. The models of cluster colors indicate that the horizontal-branch stars are the main drivers behind the empirical non-linearity. We show that the scenario gives simple and cohesive explanations for all the key observations, and could simplify theories of elliptical galaxy formation.Comment: Science, 311, 1129; Minor changes to text to match the published version (9 pages, 3 figures
