Secondary forests offset less than 10% of deforestation-mediated carbon emissions in the Brazilian Amazon
Secondary forests are increasing in the Brazilian Amazon and have been cited as an important mechanism for reducing net carbon emissions. However, our understanding of the contribution of secondary forests to the Amazonian carbon balance is incomplete, and it is unclear to what extent emissions from oldâgrowth deforestation have been offset by secondary forest growth. Using MapBiomas 3.1 and recently refined IPCC carbon sequestration estimates, we mapped the age and extent of secondary forests in the Brazilian Amazon and estimated their role in offsetting oldâgrowth deforestation emissions since 1985. We also assessed whether secondary forests in the Brazilian Amazon are growing in conditions favourable for carbon accumulation in relation to a suite of climatic, landscape and local factors. In 2017, the 129,361 km2 of secondary forest in the Brazilian Amazon stored 0.33 ± 0.05 billion Mg of aboveâground carbon but had offset just 9.37% of oldâgrowth emissions since 1985. However, we find that the majority of Brazilian secondary forests are situated in contexts that are less favourable for carbon accumulation than the biome average. Our results demonstrate that oldâgrowth forest loss remains the most important factor determining the carbon balance in the Brazilian Amazon. Understanding the implications of these findings will be essential for improving estimates of secondary forest carbon sequestration potential. More accurate quantification of secondary forest carbon stocks will support the production of appropriate management proposals that can efficiently harness the potential of secondary forests as a lowâcost, natureâbased tool for mitigating climate change
Developing an initial programme theory for a model of social care in prisons and on release (empowered together): A realist synthesis approach
Many people are living in prison with a range of social care needs, for example, requiring support with washing, eating, getting around safely, and/or maintaining relationships. However, social care for this vulnerable group is generally inadequate. There is uncertainty and confusion about who is legally responsible for this and how it can best be provided, and a lack of integration with healthcare. We used realist-informed approaches to develop an initial programme theory (IPT) for identifying/assessing social care needs of, and providing care to, male adults in prison and on release. IPT development was an iterative process involving (a) an initial scoping of the international prison literature; (b) scoping prison and community social care policy documents and guidelines; (c) full systematic search of the international prison social care literature; (d) insights from the community social care literature; (e) stakeholder workshops. Information from 189 documents/sources and stakeholder feedback informed the IPT, which recommended that models of prison social care should be: trauma-informed; well integrated with health, criminal justice, third-sector services and families; and person-centred involving service-users in all aspects including co-production of care plans, goals, and staff training/awareness programmes. Our IPT provides an initial gold standard model for social care provision for people in prison and on release. The model, named Empowered Together, will be evaluated in a future trial and will be of interest to those working in the criminal justice system, care providers and commissioners, local authorities, housing authorities, voluntary groups, and service-users and their families
"On the Spot": travelling artists and Abolitionism, 1770-1830
Until recently the visual culture of Atlantic slavery has rarely been critically scrutinised. Yet in the first decades of the nineteenth century slavery was frequently represented by European travelling artists, often in the most graphic, sometimes voyeuristic, detail. This paper examines the work of several itinerant artists, in particular Augustus Earle (1793-1838) and Agostino Brunias (1730â1796), whose very mobility along the edges of empire was part of a much larger circulatory system of exchange (people, goods and ideas) and diplomacy that characterised Europeâs Age of Expansion. It focuses on the role of the travelling artist, and visual culture more generally, in the development of British abolitionism between 1770 and 1830. It discusses the broad circulation of slave imagery within European culture and argues for greater recognition of the role of such imagery in the abolitionist debates that divided Britain. Furthermore, it suggests that the epistemological authority conferred on the travelling artistâthe quintessential eyewitnessâwas key to the rhetorical power of his (rarely her) images.
Artists such as Earle viewed the New World as a boundless source of fresh material that could potentially propel them to fame and fortune. Johann Moritz Rugendas (1802-1858), on the other hand, was conscious of contributing to a global scientific mission, a Humboldtian imperative that by the 1820s propelled him and others to travel beyond the traditional itinerary of the Grand Tour. Some artists were implicated in the very fabric of slavery itself, particularly those in the British West Indies such as William Clark (working 1820s) and Richard Bridgens (1785-1846); others, particularly those in Brazil, expressed strong abolitionist sentiments. Fuelled by evangelical zeal to record all aspects of the New World, these artists recognised the importance of representing the harsh realities of slave life. Unlike those in the metropole who depicted slavery (most often in caustic satirical drawings), many travelling artists believed strongly in the evidential value of their images, a value attributed to their global mobility. The paper examines the varied and complex means by which visual culture played a significant and often overlooked role in the political struggles that beset the period

Pilot randomised controlled trial of the ENGAGER collaborative care intervention for prisoners with common mental health problems, near to and after release
BACKGROUND: Rates of common mental health problems are much higher in prison populations, but access to primary care mental health support falls short of community equivalence. Discontinuity of care on release is the norm and is further complicated by substance use and a range of social problems, e.g. homelessness. To address these problems, we worked with criminal justice, third sector social inclusion services, health services and people with lived experiences (peer researchers), to develop a complex collaborative care intervention aimed at supporting men with common mental health problems near to and following release from prison. This paper describes an external pilot trial to test the feasibility of a full randomised controlled trial.
METHODS: Eligible individuals with 4 to 16Â weeks left to serve were screened to assess for common mental health problems. Participants were then randomised at a ratio of 2:1 allocation to ENGAGER plus standard care (intervention) or standard care alone (treatment as usual). Participants were followed up at 1 and 3Â months' post release. Success criteria for this pilot trial were to meet the recruitment target sample size of 60 participants, to follow up at least 50% of participants at 3Â months' post release from prison, and to deliver the ENGAGER intervention. Estimates of recruitment and retention rates and 95% confidence intervals (CIs) are reported. Descriptive analyses included summaries (percentages or means) for participant demographics, and baseline characteristics are reported.
RESULTS: Recruitment target was met with 60 participants randomised in 9Â months. The average retention rates were 73% at 1Â month [95% CI 61 to 83] and 47% at 3Â months follow-up [95% CI 35 to 59]. Ninety percent of participants allocated to the intervention successfully engaged with a practitioner before release and 70% engaged following release.
CONCLUSIONS: This pilot confirms the feasibility of conducting a randomised trial for prison leavers with common mental health problems. Based on this pilot study and some minor changes to the trial design and intervention, a full two-centre randomised trial assessing the clinical and cost-effectiveness of the ENGAGER intervention is currently underway
Interrogating intervention delivery and participantsâ emotional states to improve engagement and implementation: A realist informed multiple case study evaluation of Engager
BACKGROUND: 'Engager' is an innovative 'through-the-gate' complex care intervention for male prison-leavers with common mental health problems. In parallel to the randomised-controlled trial of Engager (Trial registration number: ISRCTN11707331), a set of process evaluation analyses were undertaken. This paper reports on the depth multiple case study analysis part of the process evaluation, exploring how a sub-sample of prison-leavers engaged and responded to the intervention offer of one-to-one support during their re-integration into the community. METHODS: To understand intervention delivery and what response it elicited in individuals, we used a realist-informed qualitative multiple 'case' studies approach. We scrutinised how intervention component delivery lead to outcomes by examining underlying causal pathways or 'mechanisms' that promoted or hindered progress towards personal outcomes. 'Cases' (n = 24) were prison-leavers from the intervention arm of the trial. We collected practitioner activity logs and conducted semi-structured interviews with prison-leavers and Engager/other service practitioners. We mapped data for each case against the intervention logic model and then used Bhaskar's (2016) 'DREIC' analytic process to categorise cases according to extent of intervention delivery, outcomes evidenced, and contributing factors behind engagement or disengagement and progress achieved. RESULTS: There were variations in the dose and session focus of the intervention delivery, and how different participants responded. Participants sustaining long-term engagement and sustained change reached a state of 'crises but coping'. We found evidence that several components of the intervention were key to achieving this: trusting relationships, therapeutic work delivered well and over time; and an in-depth shared understanding of needs, concerns, and goals between the practitioner and participants. Those who disengaged were in one of the following states: 'Crises and chaos', 'Resigned acceptance', 'Honeymoon' or 'Wilful withdrawal'. CONCLUSIONS: We demonstrate that the 'implementability' of an intervention can be explained by examining the delivery of core intervention components in relation to the responses elicited in the participants. Core delivery mechanisms often had to be 'triggered' numerous times to produce sustained change. The improvements achieved, sustained, and valued by participants were not always reflected in the quantitative measures recorded in the RCT. The compatibility between the practitioner, participant and setting were continually at risk of being undermined by implementation failure as well as changing external circumstances and participants' own weaknesses.

Reply to: âComment on: Orocline-driven transtensional basins: Insights from the Lower Permian Manning Basin (eastern Australia) by White et al. (2016)â
We welcome the discussion and presentation of new data by OfïŹer et al. (2017). In spite of a large number of independent evidence supporting the structure of the Manning Orocline (Cawood et al., 2011; Fielding et al., 2016; Glen & Roberts, 2012; Korsch & Harrington, 1987; Li & Rosenbaum, 2014; Mochales et al., 2014; Rosenbaum, 2012; Rosenbaum et al., 2012; White et al., 2016), OfïŹer et al. (2017) argue that this oroclinal structure does not exist. They have expressed a similar opinion in earlier discussion and comment papers (Lennox et al., 2013; OfïŹer et al., 2015). We studied the Manning Basin because we think that it is situated in the hinge of the Manning Orocline, and as such, its tectonosedimentary evolution may shed light on the oroclinal structure and its possible formation mechanisms. OfïŹer et al. (2017) mainly focus on specific structural complexities within the Manning Basin and fail to acknowledge the overwhelming volume of independent evidence supporting the proposed tectonic model. Here we address specific comments made by OfïŹer et al. (2017) and demonstrate that the new structural mapping data provided by these authors, when examined in a regional context, further support our regional interpretation for the existence and geometry of the Manning Orocline..
