Determination of cloud microphysical properties by laser backscattering and extinction measurements

The extinction and backscattering of 514 nm laser radiation in polydisperse water droplet clouds was studied in the laboratory. Three cloud size distributions with modal diameters of 0.02, 5.0, and 12.0 microns were investigated. The relationships between the cloud optical parameters (attentuation coefficient, sigma and volume backscattering coefficient, Beta (sub pi)) and the cloud water content, C, were measured for each size distribution. It was found that a linear relationship exists between sigma and C and between beta (sub pi) and C for cloud water content values up to 3gm/cubic m. The linear relationships obtained, however, have slopes which depend on the droplet size distribution. For a given water content both sigma and beta (sub pi) increase as the modal diameter decreases. The measured data are compared with existing theoretical analyses and discussed in terms of thie application to lidar measurements of atmospheric clouds. It is concluded that the empirical information obtained can serve as a basis for quantitative lidar measurements

Predicate union and the syntax of Japanese passives

This paper presents a relational account of the Japanese constructions that are commonly referred to as ‘passives’. They are shown to all be multipredicate, monoclausal constructions, with the differences between them primarily attributable to optionality in the lexical argument structure of the ‘passive’ predicate. The proposed analysis explains the differences between passives and causatives, despite their sometimes identical case-marking. Further, evidence from the interaction of unaccusative verbs and passive is shown to lead to a formal revision of the 1-Advancement Exclusiveness law. Finally, the differences between Japanese and Korean with respect to passives is reduced to a simple lexical difference between the two languages

A Current Snapshot of Institutional Repositories: Growth Rate, Disciplinary Content and Faculty Contributions

INTRODUCTION The purpose of this study was to examine current institutional repository (IR) content in order to assess the growth and breadth of content as it reflects faculty participation, and to identify successful strategies for increasing that participation. Previous studies have shown that faculty-initiated submissions to IRs, no matter the platform, are uncommon. Repository managers employ a variety of methods to solicit and facilitate faculty participation, including a variety of print marketing tools, presentations, and one-on-one consultations. METHODS This mixed method study examined faculty content in IRs through both a quantitative analysis of repository content and growth rate and a qualitative survey of repository administrators. Repositories using the Digital Commons repository platform, hosted by Berkeley Electronic Press, were examined in the fall and winter of 2013-2014 to assess the disciplinary scope of faculty content (n=107) and to measure the growth rate of IR content (n=203). Repository administrators at 205 institutions were surveyed to investigate what methods they used to facilitate faculty participation and their perceptions about the effectiveness of these methods. RESULTS Mean and median growth rates of IRs have increased since measured in 2007, with variance depending upon size and type of academic institution and age of the IR. Disciplinary content in IRs is unevenly distributed, with the Sciences predominantly represented. IR administrators remain actively involved in the submission process and in the promotion of their IRs. Personal contact with individuals or groups of faculty is the most used and successful interaction method. CONCLUSION Though IR growth rate has increased, the growth is not consistent across all IRs and does not yet pose a challenge to traditional models of scholarly publication. The rising amount of faculty content in IRs indicates faculty are increasingly willing to participate in the IR movement. However, faculty involvement may be more passive than active
