Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Wildlife Biology, EarlyView.Anthropogenic resource subsidies can drive mesopredator population growth, altering predator–prey dynamics. The red fox Vulpes vulpes is a generalist canid that can readily exploit such subsidies. In the UK, tens of millions of pheasants Phasianus colchicus and red‐legged partridges Alectoris rufa are released annually for sport shooting, potentially ...

One eight of a sphere microphone array
, 2020 Spherical microphone arrays are widespread nowadays, especially with the advent of techniques for decomposing acoustic fields on the basis of spherical harmonics (i.e. Ambisonics). However, in these approaches, the corresponding arrays require a quadratically increasing number of microphones as the degree of the components to be estimated increases ...

Methodological Challenges in Studying Wealthy Families
The British Journal of Sociology, EarlyView.ABSTRACT Studying the wealthy is not easy. This piece provides suggestions for recruitment, interview strategies, and design to gain high‐quality data on wealthy people. It is based on an interview study of 81 US racially‐diverse families with a median net worth of $25 million. First, to gain access to the wealthy, it is key for the researcher to use a

Sanctions, National Security, and Free Speech
Global Policy, EarlyView.ABSTRACT A fundamental, but largely overlooked, aspect of the New Washington Consensus is the use of national security arguments to restrict speech and punish disfavored speakers. Although the United States has a longer history of using sanctions to restrict speech in the terrorism context, it has recently applied sanctions to restrict political speech,
