Field measurements of cable self-burial in a sandy marine environment
Get PDFThe world’s shallow continental shelves are currently experiencing a rapid pace of development from the growth of offshore renewable energy. The emplacement of infrastructure on the seabed can change the morphology of the bed, the nature of the flow above it and transport of sediment and so complicate the assessment of seabed stability for planning and designing offshore renewable infrastructure. To ascertain how much of an impact these natural processes have on cable stability, we present field results from two deployments in the Eastern Irish Sea at a location of current and planned offshore windfarms. Profiles of flow, turbulence and suspended sediment concentration were measured over a section of typical high voltage electricity cable. Even during spring tides upon deployment our observations show that sediment was deposited around the cable and self-burial occurred. The rate of deposition varied between surveys dependent on forcing and local bed conditions. Turbulence generated from the cable itself reduced as the embedment depth increased, but the relationship between bed shear stress and suspended sediment concentration was not consistent between surveys. We discuss several processes potentially responsible for the prevalence of deposition around the cable, and the difference in seabed mobility between the surveys
Let there be a “We”: Introducing an Ethics of Collective Academic Care
Get PDFPurposeThis study aims to think critically about collaborative working through the practical application of an ethics of care approach. The authors address the following research questions: How can the authors embed an ethics of care into academic collaboration? What are the benefits and challenges of this kind of collaborative approach? The contextual focus also incorporates a collective sense making of academic identities over the course of the COVID-19 pandemic.Design/methodology/approachThe authors focus on the activities of the “Consumer Research with Impact for Society” collective at and around the 2021 Academy of Marketing conference. The authors draw on the insights and labour of the group in terms of individual and collaborative reflexivity, workshops and the development of a collaborative poem.FindingsFirst, the authors present the “web of words” as the adopted approach to collaborative writing. Second, the authors consider the broader takeaways that have emerged from the collaboration in relation to blurring of boundaries, care in collaboration and transformations.Originality/valueThe overarching contribution of the paper is to introduce an Ethics of Collective Academic Care. The authors discuss three further contributions that emerged as central in its operationalisation: arts-based research, tensions and conflicts and structural issues. The application of the “web of words” approach also offers a template for an alternative means of engaging with, and representing, those involved in the research
I felt like I had been put on the shelf and forgotten about” – lasting lessons about the impact of COVID-19 on people affected by rarer dementias
Get PDFBackgroundThe public health measures imposed in many countries to contain the spread of COVID-19 resulted in significant suspensions in the provision of support and care for people with dementia. The negative effects of these measures have been extensively reported. However, little is known about the specific impact on people with young onset, non-memory-led and inherited dementias. This group may have experienced different challenges compared to those with late onset dementia given their non-memory phenotypes and younger age. We explored the impact of the first COVID-19 lockdown on people living with familial Alzheimer’s disease, behavioural variant frontotemporal dementia, familial frontotemporal dementia, dementia with Lewy bodies, posterior cortical atrophy and primary progressive aphasia and their carers in the UK and their self-reported strategies for coping.MethodsThis was a mixed methods study. An online survey was administered to people with dementia and family carers recruited via Rare Dementia Support. Free-text responses were analysed using framework analysis to identify key issues and themes.Results184 carers and 24 people with dementia completed the survey. Overall, people with dementia experienced worsening of cognitive symptoms (70%), ability to do things (62%), well-being (57%) and changes to medication (26%) during lockdown. Carers reported a reduction in the support they received (55%) which impacted their own mental health negatively. Qualitative analysis of free-text responses shed light on how the disruption to routines, changes to roles and responsibilities, and widespread disconnection from friends, family and health and social care support varied according to phenotype. These impacts were exacerbated by a more general sense that precious time was being lost, given the progressive nature of dementia. Despite significant challenges, respondents demonstrated resilience and resourcefulness in reporting unexpected positives and strategies for adapting to confinement.ConclusionsThis study has highlighted the specific impacts of the COVID-19 restrictions on people with young onset, non-memory-led and inherited dementias, including behavioural variant frontotemporal dementia, primary progressive aphasia and posterior cortical atrophy, and their carers. The specific challenges faced according to diagnosis and the self-reported strategies speak to the importance of – and may inform the development of – tailored support for these underrepresented groups more generally
Interventions targeting the mental health and wellbeing of care-experienced children and young people in higher-income countries:Evidence map and systematic review
Get PDFBACKGROUND: The mental health and wellbeing of care-experienced children and young people (i.e. foster care, kinship care, residential care) is poorer than non-care-experienced populations. The Care-experienced cHildren and young people's Interventions to improve Mental health and wEll-being outcomes Systematic review (CHIMES) aimed to synthesise the international evidence base for interventions targeting subjective wellbeing, mental health and suicide amongst care-experienced young people aged ≤ 25 years.METHODS: For the first phase of the review, we constructed an evidence map identifying key clusters and gaps in interventions and evaluations. Studies were identified through 16 electronic databases and 22 health and social care websites, in addition to expert recommendations, citation tracking and screening of relevant systematic reviews. We charted interventions and evaluations with a summary narrative, tables and infographics.RESULTS: In total, 64 interventions with 124 associated study reports were eligible. The majority of study reports were from the USA (n = 77). Interventions primarily targeted children and young people's skills and competencies (n = 9 interventions), the parental functioning and practices of carers (n = 26), or a combination of the two (n = 15). While theoretically under-specified, interventions were largely informed by theories of Attachment, Positive Youth Development, and Social Learning Theory. Current evaluations prioritised outcomes (n = 86) and processes (n = 50), with a paucity of study reports including theoretical descriptions (n = 24) or economic evaluations (n = 1). Interventions most frequently targeted outcomes related to mental, behavioural or neurodevelopmental disorders, notably total social, emotional and behavioural problems (n = 48 interventions) and externalising problem behaviours (n = 26). There were a limited number of interventions targeting subjective wellbeing or suicide-related outcomes.CONCLUSIONS: Future intervention development might focus on structural-level intervention theories and components, and target outcomes related to subjective wellbeing and suicide. In accordance with current methodological guidance for intervention development and evaluation, research needs to integrate theoretical, outcome, process and economic evaluation in order to strengthen the evidence base.SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020177478.</p
Can temperate forests deliver future wood demand and climate mitigation?
Get PDFGlobal wood demand is projected to rise but supply capacity is questioned due to limited global forest resources. Furthermore, the lifecycle global warming potential (GWP) impact of additional wood supply and use is poorly understood. For the case of a temperate country, combining forest carbon modelling and life-cycle assessment we show that sustained afforestation to double forest area alongside enhanced productivity can meet lower-bound wood demand projections from 2058. Thus, temperate forestry value-chains can achieve a cumulative GWP benefit of up to 265 Tg CO2-equivalent (CO2e) by 2100 for each 100,000 ha (expanding to 200,000 ha through afforestation) of forest. Net GWP balance depends on which overseas forests supply domestic shortfalls, how wood is used, and rate of industrial decarbonisation. There is considerable but constrained potential for increased wood-use to deliver future climate-change mitigation, providing it is connected with a long-term planting strategy, enhanced tree productivity and efficient wood use

Get PDFEffectiveness of out-patient based acute heart failure care: A pilot randomised controlled trial
Get PDFObjectives: Acute heart failure (AHF) hospitalisation is associated with 10% mortality. Outpatient based management (OPM) of AHF appeared effective in observational studies. We conducted a pilot randomised controlled trial (RCT) comparing OPM with standard inpatient care (IPM).Methods: We randomised patients with AHF, considered to need IV diuretic treatment for >2 days, to IPM or OPM. We recorded all-cause mortality, and the number of days alive and out-of-hospital (DAOH). Quality of life, mental well-being and Hope scores were assessed. Mean NHS cost savings and 95% central range (CR) were calculated from bootstrap analysis.Follow-up: 60 days.Results: Eleven patients were randomised to IPM and thirteen to OPM. There was no statistically significant difference in all-cause mortality during the index episode (1/11 vs 0/13) and up to 60 days follow-up (2/11 vs 2/13) [p=0.86]. The OPM group accrued more DAOH {47 [36,51] vs 59 [41,60], p=0.13}. Two patients randomised to IPM (vs 6 OPM) were readmitted [p=0.31]. Hope scores increased more with OPM within 30 days but dropped to lower levels than IPM by 60 days. More out-patients had increased total well-being scores by 60 days (p=0.04). OPM was associated with mean cost savings of £2,658 (95% CR 460 - 4,857) per patient.Conclusions: Patients with acute HF randomised to OPM accrued more days alive out of hospital (albeit not statistically significantly in this small pilot study). OPM is favoured by patients and carers and is associated with improved mental well-being and cost savings.<br/
