Destruction of dimethyl ether and methyl formate by collisions with He$^+$

, 2019
To correctly model the abundances of interstellar complex organic molecules (iCOMS) in different environments, both formation and destruction routes should be appropriately accounted for.

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

The Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

The Role of Dice in the Emergence of the Probability Calculus

International Statistical Review, EarlyView.
Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

Shedding light on the environmental efficiency of the public light service: minimising light pollution through the global Malmquist–Luenberger index

International Transactions in Operational Research, EarlyView.
Abstract The search for evidence in public management and the implementation of good management by public bodies is becoming increasingly important, and the principles of effectiveness and efficiency should be reinforced. Therefore, this paper aims to analyse the change in efficiency in the provision of public lighting services by local governments ...

Observatory/data centre partnerships and the VO-centric archive: The JCMT Science Archive experience

, 2014
We present, as a case study, a description of the partnership between an observatory (JCMT) and a data centre (CADC) that led to the development of the JCMT Science Archive (JSA).

The Development and Validation of Models of Risk for Behaviours That Challenge in Children With Developmental Disabilities: A Novel Machine Learning Approach

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Children with developmental disabilities show a high prevalence of behaviours that challenge (BtC). Thus, harnessing known risk markers to target early intervention to children at the greatest risk of BtC is essential. In this study, machine learning techniques were used to develop prediction models of risk (no, low and high ...

New knowledge about shock events that affected the L‐chondrite parent body from two heavily shocked L6 meteorite finds

Meteoritics &Planetary Science, EarlyView.
Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.
