Are risk factors for drug use and offending similar during the teenage years?

BackgroundThis paper explores whether at different stages of the developmental cycle of adolescence, drug use and offending are associated with a similar set of risk factors relating to: socio-structural position, informal social control, deviant peer group contexts, and deviant lifestyle behaviours.MethodsMultivariate regression was used to analyse data from the Edinburgh Study of Youth Transitions and Crime (ESYTC) self-report questionnaire.ResultsEarly in the teenage years drug use was associated with a similar set of factors to offending. These include weak bonds to parents and teachers, and deviant lifestyle behaviours. However, later in the teenage years there were differences, e.g. drug use was associated with higher socio-economic status and importance of school, and a number of factors which were associated with offending were not associated with drug use, e.g. parent-child conflict, gang membership and hanging around.ConclusionResults show that the factors included here are more appropriate to understanding offending than drug use. Different risk factors are associated with drug use and offending in the older, but not younger teens. It is argued that later in the teenage years drug use should be understood and addressed differently to offending. This is particularly important given the tendency for the ‘drugs problem’ to increasingly be dealt with as a ‘crime problem’ (Duke, 2006)

‘Free text is essentially the enemy of what we’re trying to achieve’: the framing of a national vision for delivering digital police contact

Police organisations in England and Wales, as in many other contexts, are increasingly shifting crime reporting and other public-facing contact online. In this paper we explore the beliefs, motivations, and objectives of those tasked with ‘delivering’ the ‘vision’ of digital police contact at the strategic national level. We use Goffman’s concept of frames – the set of expectations an actor brings to a situation or process – to understand how participants enacted this 'channel shift’ (Wells et al., 2023), the ends they were seeking to meet, and how different interests came to be designed-in to the contact architecture. We suggest that the primary frame centred around notions of efficiency and demand management. Running alongside this is a secondary frame of customer service, where it is assumed that the public also wish for the efficient delivery of this technologically mediated service. This, we suggest, is likely to be only a partial reflection of what people want when contacting police; but the framing of 'contact’ as a separate deliverable by those delivering this agenda serves to occlude or evade this point. Technology, we argue, imprints itself on the context by appearing to offer a convenient solution to problems of public wants and police needs

‘Channel Shift’:technologically-mediated policing and procedural justice

In recent years, police forces in the United Kingdom have introduced various technologies that alter the methods by which they interact with the public. In a parallel development, many forces have also begun to embrace the concept of procedural justice as a method through which to secure legitimacy and (in turn) public compliance and cooperation. What has not received sufficient attention, within policing or academia, is the extent to which these two trends are compatible, with the procedural justice literature still predicated on an assumption that police–public ‘contacts’ or ‘encounters’ are in-person. The effect of technologically mediating police–public contacts on ‘policing by consent’, is therefore unknown. In this article, we focus specifically on the possible implications of the Single Online Home (SOH) (a portal through which the public can report crime, get updates on cases, give feedback and pay fines, among other things, which is currently being rolled out across forces), considering ‘interactions’ between police and public where there is no physical co-presence. Noting the unique context that is policing, we draw on the limited existing research on procedural justice encounters in technologically mediated contexts to explore whether procedural justice theory is ‘future-proof’ for a policing context increasingly reliant on such encounters. We conclude that, through empirical research, we must update our conceptual understanding of what ‘contact’ can mean, and accept that current developments may in fact be transforming relationships rather than simply facilitating existing ones

Monotonicity of Fitness Landscapes and Mutation Rate Control

A common view in evolutionary biology is that mutation rates are minimised. However, studies in combinatorial optimisation and search have shown a clear advantage of using variable mutation rates as a control parameter to optimise the performance of evolutionary algorithms. Much biological theory in this area is based on Ronald Fisher's work, who used Euclidean geometry to study the relation between mutation size and expected fitness of the offspring in infinite phenotypic spaces. Here we reconsider this theory based on the alternative geometry of discrete and finite spaces of DNA sequences. First, we consider the geometric case of fitness being isomorphic to distance from an optimum, and show how problems of optimal mutation rate control can be solved exactly or approximately depending on additional constraints of the problem. Then we consider the general case of fitness communicating only partial information about the distance. We define weak monotonicity of fitness landscapes and prove that this property holds in all landscapes that are continuous and open at the optimum. This theoretical result motivates our hypothesis that optimal mutation rate functions in such landscapes will increase when fitness decreases in some neighbourhood of an optimum, resembling the control functions derived in the geometric case. We test this hypothesis experimentally by analysing approximately optimal mutation rate control functions in 115 complete landscapes of binding scores between DNA sequences and transcription factors. Our findings support the hypothesis and find that the increase of mutation rate is more rapid in landscapes that are less monotonic (more rugged). We discuss the relevance of these findings to living organisms

Challenges for drug checking services in a Scottish context: a qualitative exploration of police perceptions

BackgroundThe impact of policing practices on the engagement of people who use drugs (PWUD) with harm reduction services is well evidenced. Although the police have traditionally taken an enforcement role in responding to drug use, it is increasingly clear that they can play an important part in multiagency delivery of harm reduction interventions. Despite this, there have been no studies exploring police officer perceptions of drug checking services (DCS), which provide analytical testing of client drug samples alongside harm reduction support and advice.MethodsSemi-structured interviews were conducted with 10 police officers to explore the policing and legal challenges which could be encountered in the delivery of DCS in Scotland.ResultsParticipants expressed general support for DCS and described this support as part of a wider organisational shift towards public health-oriented policing. Participants also discussed different potential approaches to the policing of areas surrounding DCS including: formal limits on police presence around the service and/or stop and search powers in relation to personal possession; the effective decriminalisation of personal possession within a specified boundary around the service; and informal agreements between local divisions and DCS outlining expected policing practices. Any formal limitation on the capacity of police officers to respond to community concerns was viewed as problematic and as having the potential to erode public confidence in policing. Participants also highlighted the potential for frontline officers to utilise discretion in ways which could undermine public health goals. Legislative change, or national strategic guidance from relevant stakeholders, was seen as a means of providing ‘cover’, enabling local divisions to support the operation of drug checking.ConclusionsDespite a small sample of participants, this study summarises key challenges to be addressed in the implementation and operation of DCS in Scotland, and more widely. The paper concludes with suggested opportunities to develop approaches to policing that can facilitate rather than impede implementation and operation of these services

Planning and implementing community-based drug checking services in Scotland: a qualitative exploration using the consolidated framework for implementation research

Background: Drug checking services (DCS) provide harm reduction support and advice to individuals based on chemical analysis of submitted substances of concern. Whilst there are currently no DCS in Scotland, community-based services are being planned in three cities. Methods: In this paper, we report qualitative findings based on interviews with 43 participants, focused on perceptions of DCS and their implementation. Participants were relevant professionals, those with experience of drug use, and family members of those with experience of drug use. The Consolidated Framework for Implementation Research (CFIR) was used to inform data collection and analysis. We report findings under nine constructs/themes across the five CFIR domains. Results: Participants noted the importance of DCS being implemented in low-threshold, trusted services with a harm reduction ethos, and outlined a range of further service design considerations such as speed of testing, and information provided through the analysis process. In relation to the ‘inner setting’, a key finding related to the potential value of leveraging existing resources in order to expand both reach and effectiveness of drug trend communication. The approach of local and national police to DCS, and the attitudes of the public and local community, were described as important external factors which could influence the success (or otherwise) of implementation. Bringing together a range of stakeholders in dialogue and developing tailored communication strategies were seen as ways to build support for DCS. Overall, we found high levels of support and perceived need for DCS amongst all stakeholder groups. Conclusions: Our findings present initial implementation considerations for Scotland which could be further explored as DCS are operationalised. Further, our focus on implementation contexts is relevant to research on DCS more generally, given the minimal consideration of such issues in the literature

A Realist Review of How Community-Based Drug Checking Services Could Be Designed and Implemented to Promote Engagement of People Who Use Drugs

With rising numbers of drug-related deaths in the UK and globally, exploration of interventions that seek to reduce drug-related harm is essential. Drug checking services (DCS) allow people to submit drug samples for chemical analysis and receive feedback about the sample, as well as harm reduction advice. The use of DCS is often linked to festival and/or nightlife settings and to so-called ‘recreational’ drug use, but research has also shown the potential of community-based DCS as an intervention serving more varied demographics of people who use drugs, including more marginalised individuals and those experiencing drug dependence. Whilst there is a growing evidence base on the effectiveness of drug checking as a harm reduction intervention, there is still limited evidence of the underlying mechanisms and processes within DCS which may aid implementation and subsequent engagement of people who use drugs. This presents a challenge to understanding why engagement differs across types of DCS, and how best to develop and deliver services across different contexts and for different populations. To explore the contexts and mechanisms which impact engagement in community-based DCS, a realist review was undertaken to synthesise the international evidence for the delivery and implementation of DCS. There were 133 sources included in the review. From these sources the underlying contexts, mechanisms, and outcomes relating to DCS implementation and engagement were developed and refined into seven programme theories. The findings of this review are theoretically novel and hold practical relevance for the design of DCS, with implications for optimisation, tailoring, and implementing services to reach individuals in different settings
