We examine the dynamic relations between institutional ownership and a firm's capital structure. We find that a firm's leverage decreases when institutional ownership increases. This result implies that a firm reduces its debt level as institutional investors substitute for the monitoring role...

This article studies a sample of 225 Chinese A-share Seasoned Equity Offerings (SEOs) from 1999 to 2007. We compare a novel underpricing measure with a Stochastic Frontier Approach (SFA) as in Koop and Li (2001) to the conventional measure based on the difference between primary market price and...

We propose a new model for conditional covariances based on predetermined idiosyncratic shocks as well as macroeconomic and <italic>own</italic> information instruments. The specification ensures positive definiteness by construction, is unique within the class of linear functions for our covariance...

Genome-wide association studies are now widely used tools to identify genes and/or regions which may contribute to the development of various diseases. With case-control data a 2x3 contingency table can be constructed for each SNP to perform genotype-based tests of association. An increasingly...

Porous NiTi shape memory alloy (SMA) with 48% porosity and an average pore size of 50–800 μm was synthesized by capsule-free hot isostatic pressing (CF-HIP). To enhance the surface bioactivity, the porous NiTi SMA was subjected to H2O2 and subsequent NaOH treatment. Scanning electron...

A method is presented for impact evaluation of dams/sluices on their downstream aquatic ecosystems in the absence of detailed long-sequence ecology ecosystem data. It is based on the analysis of relations between indices of water quality and aquatic organisms. It can be applied to a river...
