Development and Flight Results from the C3D2 Imager Payload on AlSat Nano

An experimental CubeSat camera system using 3 separate CMOS imagers was flown in 2014 on UKube-1. In response to an announcement opportunity in December 2014, we proposed an upgrade to our C3D imager payload, which was accepted to fly on AlSat Nano. Launched in September 2016 the system has been operational for over 1 year and has returned both images and housekeeping data, including detailed temperature and radiation dosimetry measurements. Through these in-orbit demonstrations on CubeSans, the image sensors and payload have attained TRL9, and these are now being used in other flight opportunities. In this paper we describe the C3D imager payload, which comprises 3 independent CMOS image sensors used in different camera systems; two wide field cameras are specifically optimised with one to observe the Earth from the 650 km orbit, and the other with its focus set to 40 cm to observe a deployable boom from the CubeSat. The experiment controller also contained thermometry and two RADFET dosimeters, one located on the payload, with the other deployed at a different point on the spacecraft. In this paper we will describe the experiment design and operational performance, and review the in-orbit data obtained during the operations covering over 17 months in-orbit, in addition to discussing lessons learned from the flight experience. We also discuss further developments of the payload concept which we are currently working on toward future flight opportunities

Producing the 'problem of drugs': a cross national-comparison of ‘recovery' discourse in two Australian and British reports

The notion of ‘recovery’ as an overarching approach to drug policy remains controversial. This cross-national analysis considers how the problem of drugs was constructed and represented in two key reports on the place of ‘recovery’ in drug policy, critically examining how the problem of drugs (and the people who use them) are constituted in recovery discourse, and how these problematisations are shaped and disseminated. Bacchi's poststructuralist approach is applied to two documents (one in Britain and one in Australia) to analyse how the ‘problem of drugs’ and the people who use them are constituted: as problematic users, constraining alternative understandings of the shifting nature of drug use; as responsibilised individuals (in Britain) and as patients (in Australia); as worthy of citizenship in the context of treatment and recovery, silencing the assumption of unworthiness and the loss of rights for those who continue to use drugs in ‘problematic’ ways. The position of the organisations which produced the reports is considered, with the authority of both organisations resting on their status as independent, apolitical bodies providing ‘evidence-based’ advice. There is a need to carefully weigh up the desirable and undesirable political effects of these constructions. The meaning of ‘recovery’ and how it could be realised in policy and practice is still being negotiated. By comparatively analysing how the problem of drugs was produced in ‘recovery’ discourse in two jurisdictions, at two specific points in the policy debate, we are reminded that ways of thinking about ‘problems’ reflect specific contexts, and how we are invoked to think about policy responses will be dependent upon these conditions. As ‘recovery’ continues to evolve, opening up spaces to discuss its contested meanings and effects will be an ongoing endeavour

The shifting roles of medical stakeholders in opioid substitution treatment: a comparison between Denmark and the UK

Purpose – The purpose of this paper is to examine the shifting roles of medical professionals as stakeholders in opioid substitution treatment (OST) policies and practices in Denmark and the UK within the past 15 years. Design/methodology/approach – The paper is based on literature reviews, documentary analyses and key informant interviews with a range of stakeholders involved in OST and policy in Denmark and UK. The study is part of the EU-funded project: Addictions and Lifestyles in Contemporary Europe: Reframing Addictions Project. Findings – Denmark and the UK are amongst those few European countries that have long traditions and elaborate systems for providing OST to heroin users. The UK has a history of dominance of medical professionals in drugs treatment, although this has been recently challenged by the recovery movement. In Denmark, a social problem approach has historically dominated the field, but a recent trend towards medicalisation can be traced. As in all kinds of policy changes, multiple factors are at play when shifts occur. We examine how both countries’ developments around drugs treatment policy and practice relate to broader societal, economic and political changes, how such divergent developments emerge and how medical professionals as stakeholders enhanced their roles as experts in the field through a variety of tactics, including the production and use of “evidence”, which became a key tool to promote specific stakeholder’s perspectives in these processes. Originality/value – The paper contributes to current policy and practice debates by providing comparative analyses of drug policies and examination of stakeholder influences on policy processes

Challenges to providing culturally sensitive drug interventions for black and Asian minority ethnic (BAME) groups within UK youth justice systems

To explore how substance use practitioners intervene with ethnically and culturally diverse groups of young people in contact with the youth justice system. Telephone, face to face interviews and a focus group were conducted. Data were analysed thematically using a frame reflective theoretical approach. Practitioners tended to offer individualised interventions to young people in place of culturally specific approaches partly due to a lack of knowledge, training or understanding of diverse cultural needs, and for practical and resource reasons. Practitioners reject the official narrative of BAME youth in the justice system as dangerous and in need of control, viewing them instead as vulnerable and in need of support but report they lack experience, and sufficient resources, in delivering interventions to diverse groups. There is little information regarding how practitioners respond to diversity in their daily practice. This paper is an exploration of how diversity is framed and responded to in the context of youth substance use and criminal justice
