How Close Are Close Shareholder Votes?

The Review of Financial Studies, 2018
Abstract We show that close votes on shareholder proposals are disproportionately more likely to be won by management than by shareholder activists. Using a sample of shareholder proposals from 2003 to 2016, we uncover a large and discontinuous drop in the density of voting results at the 50% threshold.

Tuning VSV-G Expression Improves Baculovirus Integrity, Stability and Mammalian Cell Transduction Efficiency

Viruses
Baculoviral vectors (BVs) derived from Autographa californica multiple nucleopolyhedrovirus (AcMNPV) are an attractive tool for multigene delivery in mammalian cells, which is particularly relevant for CRISPR technologies.
