The Dead Butler revisited: grammatical accuracy and clarity in the English Primary Curriculum 2013–2014
This paper is an analysis of the strengths and weaknesses of the grammatical description and advice contained in the new National Curriculum documentation from 2013, focusing on key stages 1 and 2. It builds on previous analyses of deficiencies in the systems of grammar and the materials in earlier incarnations of the National Curriculum. It suggests that there have been advances in the accuracy with which grammar terms are used and illustrated, although there is still no coherent overall view of what grammar is, nor a fully consistent approach to describing language. In addition, the lack of any pedagogic guidance save the most basic suggests that knowledge about language may continue to be taught in a way which is incompatible with real understanding and more in line with prescriptivist approaches

Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background
The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitational waves. While general relativity allows for only two tensor gravitational-wave polarizations, general metric theories can additionally predict two vector and two scalar polarizations. The polarization of gravitational waves is encoded in the spectral shape of the stochastic gravitational-wave background, formed by the superposition of cosmological and individually unresolved astrophysical sources. Using data recorded by Advanced LIGO during its first observing run, we search for a stochastic background of generically polarized gravitational waves. We find no evidence for a background of any polarization, and place the first direct bounds on the contributions of vector and scalar polarizations to the stochastic background. Under log-uniform priors for the energy in each polarization, we limit the energy densities of tensor, vector, and scalar modes at 95% credibility to Ω0T<5.58×10-8, Ω0V<6.35×10-8, and Ω0S<1.08×10-7 at a reference frequency f0=25 Hz. © 2018 American Physical Society
