UK police services constantly endure pressures to reduce spending and to reorganise in ways thought to be more efficient. In these moments of scrutiny, non-standard work practices become more noticeable. We report a study of a specialist unit, the Child Protection Unit (CPU), in one police service. In 2011, an initial exploratory interview with the unit head was followed by two discussion groups carried out with a three month gap between them. We found the unit existing and working dynamically between two forces: (a) the needs and expectations of society regarding child protection and (b) how more general expectations and needs regarding crime are normally met by the police service. While 'traditional' policing might see the offender successfully prosecuted, there can be deleterious effects on the victim. In consequence, CPU members are: more focused on and sensitive to the victim leading to a risk management philosophy; are more team-oriented with greater awareness of and sense of responsibility for each other; receive greater public support than other parts of the service. These differences result in the CPU members having non-standard organisational and operational work practices: they are less performance target-based; they investigate and prosecute a smaller number of cases; they use different documentation; they are not available to help with other work at times of greater general demand on the police service. Thus existing dynamically and anomalously, the unit's very vulnerability that helps its members to do their difficult job also raises their profile and increases vulnerability to financial cuts. Their precipice in the title quotation is at several levels. We theorise our findings using contingency and cultural theories believing the findings relevant to other organisations with specialist units.
The division between stripped-envelope supernovae (SE-SNe) and superluminous supernovae (SLSNe) is not well-defined in either photometric or spectroscopic space. While a sharp luminosity threshold has been suggested, there remains an increasing number of transitional objects that reach this threshold without the spectroscopic signatures common to SLSNe. In this work, we present data and analysis on four SNe transitional between SE-SNe and SLSNe; the He-poor SNe 2019dwa and 2019cri, and the He-rich SNe 2019hge and 2019unb. Each object displays long-lived and variable photometric evolution with luminosities around the SLSN threshold of Mr < -19.8 mag. Spectroscopically however, these objects are similar to SE-SNe, with line velocities lower than either SE-SNe and SLSNe, and thus represent an interesting case of rare transitional events. ; KM, MRM, and SJP are supported by H2020 ERC grant no. 758638.

This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands.
