Prior reviews suggest that improving street lighting leads to a decrease in offending, but little is known about the effects of switching off street lighting. The present research investigates the effects of switching off street lighting in Maldon, Essex, by comparing police-recorded crime rates before and after, in Maldon and in the adjacent area of Braintree, Essex. After street lighting was switched off, burglary and vehicle crime increased relatively in Maldon, but criminal damage did not change, and violence decreased relatively in Maldon. Since violence is a costly crime, switching off street lighting in Maldon was not followed by an increase in the costs of crime. Possible explanations of these findings are discussed, including the fact that switching off street lighting in Maldon might have deterred people from going out at night.

Working in an idealised framework in which a series of phases of evolution defined by the second slow-roll parameter η  are matched together, we calculate the reduced bispectrum, f NL, for models of inflation with a large peak in their primordial power spectra. We find f NL is typically approximately constant over scales at which the peak is located, and provide an analytic approximation for this value. This allows us to identify the conditions under which f NL is large enough to have a significant impact on the resulting production of primordial black holes (PBHs) and scalar induced gravitational waves (SIGWs). Together with analytic formulae for the gradient of the rise and fall in the power spectrum, this provides a toolkit for designing or quickly analysing inflationary models that produce PBHs and SIGWs.

In this article, we examine the role, status and autonomy of teachers at English private accountancy tuition providers from 1980 to the present. We argue that, during this period, teachers transformed from ‘rock stars’ who enjoyed significant status and autonomy over their work to ‘hygiene factors’ in a largely standardised and commodified teaching environment. Growing cost pressures on tuition providers and an increasing emphasis on the quality and consistency of the learning experience are identified as significant factors in this transformation. We discuss these findings with reference to current developments towards corporatisation and marketisation in the English higher education sector.
