THE EXPANDED CITY - STAGE TWO

For 10 years In Certain Places has focused on and shaped developments within the city centre of Preston. The Expanded City is a three-stage programme of artistic research, interventions and events, designed to inform a series of planned infrastructure projects on the outskirts of Preston. Part of Preston’s ‘City Deal’ – a central government initiative which aims to encourage economic growth by addressing strategic infrastructure challenges – the scheme includes the creation of over 17,000 houses as well as new roads and amenities. In the first stage of The Expanded City project (2015-2016) commissioned artists Olivia Keith, Gavin Renshaw, Emily Speed and duo Ian Nesbitt and Ruth Levene investigated the physical and cultural topography of the outskirts of Preston, ‘deep mapping’ the areas marked for growth. The artists share an interest in boundaries, routes, edges and the urban/rural binary, and work across a range of media, including film, photography and performance. This second phase running from 2017 until 2018 was a continuation of the artists' active research and saw the project expand with a series of Network events which brought external perspectives from experts and local communities directly into the development of the artists’ work. These included; Ruth Levene and Ian Nesbitt's 'Precarious Landscape Bus Tour' with archaeologist Bob Johnston; Gavin Renshaw's 'Routes in, Routes Out' in conversation event with cycling journalist Jack Thurston; Olivia Keith two week residency at the Final Whistle Cafe in Cottam culminating in a workshop 'Traces of Place'; Emily Speed's in conversation event with architect Lee Ivett on the topic of playspace 'What do we need in a Space for Play?'; and Lauren Velvick's 'Open House' event, an informal evening of music and discussion about the politics and practicalities of housing, leading to the creation of an 'Open House' publication. The second phase featured the 'Lie of the Land' symposium, a day of artworks, presentations and conversations, which drew on research undertaken by the artists to explore how our everyday lives are shaped by the ownership, management and development of land. The symposium featured talks by Peter Hetherington – journalist and author of the book 'Whose Land is Our Land: The use and abuse of Britain’s forgotten acres', and Julia Heslop – a Newcastle-based artist whose self-build housing project, 'Protohome' (2016), examined participatory alternatives to mainstream housing provision. The event also included a bus tour to sites in and around Preston, during which The Expanded City artists presented their research into issues of housing, cycling infrastructure and the changing landscape. The symposium was accompanied by 'The Expanded City Map' created by artist Claire Tindale. The map geographically locates and gives details of the main research insights generated through the projects by the commissioned artists This phase saw the finalisation by The Decorators of two pieces emerging from their research the 'Learning from Preston' report and the 'Garstang Road Stories' audio artwork. (https://podtail.com/en/podcast/the-decorators-on-air/garstang-road-stories/) Ruth Levene and Ian Nesbitt's research culminated in May 2018 with them curating 'Notes from a Precarious Landscape' – a community exhibition curated by in a vacant house in a new development in Cottam, North Preston, which included contributions from residents of Preston and its surrounding villages. The exhibition explored the ways in which the land around the city is changing or has changed in the past. Emily Speed’s research in phase two of The Expanded City culminated in the project ‘Model Village?’ in June 2018, during which she worked with members of the public, including local residents and school pupils of all ages to construct a temporary model village on the site of a housing development. Participants were asked ‘What would your dream place to live or play in look like?’ and had the opportunity to use coloured clay to build their ideal home, and make a mark on the village by creating, extending, squashing or customising its buildings, trees, parks and streets. Gavin Renshaw's research in this phase concluded with the production of a cycling map for Preston which collates routes, information relevant to cyclists, such as storage, topography and traffic black spots, and existing cycle infrastructure within a single, visual inventory. Olivia Keith's project 'Traces of Place' involved a two-week residency at the Final Whistle Café in Cottam during the summer of 2017, in which she collated memories and contributions from local people.. As a direct result of her work and the conversations hosted, Olivia was invited to contribute to the 'Streets of Change: Beattie’s Preston and Beyond' exhibition at the Harris Museum and Art Gallery, where she created 'Setting in Place: The Making of a Jellied Map of Nether Bartle' a performance installation in two separate venues, Bartle Hall and Harris Museum & Art Gallery, Preston. Another outcome from her research was the creation of a linocut 'Nether Bartle map' as a prompt for discussions around naming and place. The Expanded City has been developed in response to an invitation from Preston City Council, to inform a programme of infrastructure projects on the outskirts of the city proposed by a £430m City Deal scheme. The City Deal scheme aims to deliver new jobs and housing, by addressing strategic transport, environmental, community and cultural infrastructure challenges

Consequences of gas flux model choice on the interpretation of metabolic balance across 15 lakes

Ecosystem metabolism and the contribution of carbon dioxide from lakes to the atmosphere can be estimated from free-water gas measurements through the use of mass balance models, which rely on a gas transfer coefficient (k) to model gas exchange with the atmosphere. Theoretical and empirically based models of k range in complexity from wind-driven power functions to complex surface renewal models; however, model choice is rarely considered in most studies of lake metabolism. This study used high-frequency data from 15 lakes provided by the Global Lake Ecological Observatory Network (GLEON) to study how model choice of k influenced estimates of lake metabolism and gas exchange with the atmosphere. We tested 6 models of k on lakes chosen to span broad gradients in surface area and trophic states; a metabolism model was then fit to all 6 outputs of k data. We found that hourly values for k were substantially different between models and, at an annual scale, resulted in significantly different estimates of lake metabolism and gas exchange with the atmosphere

“Did I bring it on myself?” An exploratory study of the beliefs that adolescents referred to mental health services have about the causes of their depression

Background: The causal beliefs which adults have regarding their mental health difficulties have been linked to help-seeking behaviour, treatment preferences and the outcome of therapy; yet the topic remains a relatively unexplored one in the adolescent literature. Aims: This exploratory study aims to explore the causal beliefs regarding depression among a sample of clinically referred adolescents. Design: 77 adolescents, aged between 11 and 17, all diagnosed with moderate to severe depression, were interviewed using a semi-structured interview schedule, at the beginning of their participation in a randomised controlled trial. Data were analysed qualitatively using Framework Analysis. Findings: The study identified three themes related to causal beliefs: 1) Bewilderment about why they were depressed; 2) Depression as a result of rejection, victimisation and stress; and 3) Something inside is to blame. Conclusion: Although some adolescents struggled to identify the causes of their depression, many identified stressful life experiences as the cause of their current depression. They also tended to emphasise their own negative ways of interpreting those events, and some believed that their depression was caused by something inside them. Adolescents’ causal beliefs are likely to have implications for the way they seek help and engage in treatment, making it important to understand how adolescents understand their difficulties

Molecular control of stomatal development

Plants have evolved developmental plasticity which allows the up- or down-regulation of photosynthetic and water loss capacities as new leaves emerge. This developmental plasticity enables plants to maximise fitness and to survive under differing environments. Stomata play a pivotal role in this adaptive process. These microscopic pores in the epidermis of leaves control gas exchange between the plant and its surrounding environment. Stomatal development involves regulated cell fate decisions that ensure optimal stomatal density and spacing, enabling efficient gas exchange. The cellular patterning process is regulated by a complex signalling pathway involving extracellular ligand-receptor interactions, which, in turn, modulate the activity of three master transcription factors essential for the formation of stomata. Here, we review the current understanding of the biochemical interactions between the epidermal patterning factor ligands and the ERECTA family of leucine-rich repeat receptor kinases. We discuss how this leads to activation of a kinase cascade, regulation of the bHLH transcription factor SPEECHLESS and its relatives, and ultimately alters stomatal production

Resolving identity ambiguity through transcending fandom

Identity construction involves accumulating cultural, social, and symbolic capital, with initial endowments being accrued through socialization into one’s habitus. This research explores the experiences of individuals that feel a lack of capital, which leads to ambiguity regarding their identities and places in the world. Through in-depth interviews, this interpretive research shows that such individuals may turn to fandom for gaining status and belonging. Fandoms are consumption fields with clear, limited forms of cultural capital. Through serial fandom and engagement with fandom in different ways, individuals were able to learn the skill of identifying and accruing relevant cultural capital. The skill became decontextualized and recontextualized, allowing individuals to transcend fandom and accrue general forms of cultural capital. Learning the skill aids individuals in dealing with the simultaneously debilitating and empowering freedom of contemporary consumer culture. Moreover, gaining cultural capital could be altogether developing into the form of the process we describe

Adjunctive rifampicin for Staphylococcus aureus bacteraemia (ARREST): a multicentre, randomised, double-blind, placebo-controlled trial.

BACKGROUND: Staphylococcus aureus bacteraemia is a common cause of severe community-acquired and hospital-acquired infection worldwide. We tested the hypothesis that adjunctive rifampicin would reduce bacteriologically confirmed treatment failure or disease recurrence, or death, by enhancing early S aureus killing, sterilising infected foci and blood faster, and reducing risks of dissemination and metastatic infection. METHODS: In this multicentre, randomised, double-blind, placebo-controlled trial, adults (≥18 years) with S aureus bacteraemia who had received ≤96 h of active antibiotic therapy were recruited from 29 UK hospitals. Patients were randomly assigned (1:1) via a computer-generated sequential randomisation list to receive 2 weeks of adjunctive rifampicin (600 mg or 900 mg per day according to weight, oral or intravenous) versus identical placebo, together with standard antibiotic therapy. Randomisation was stratified by centre. Patients, investigators, and those caring for the patients were masked to group allocation. The primary outcome was time to bacteriologically confirmed treatment failure or disease recurrence, or death (all-cause), from randomisation to 12 weeks, adjudicated by an independent review committee masked to the treatment. Analysis was intention to treat. This trial was registered, number ISRCTN37666216, and is closed to new participants. FINDINGS: Between Dec 10, 2012, and Oct 25, 2016, 758 eligible participants were randomly assigned: 370 to rifampicin and 388 to placebo. 485 (64%) participants had community-acquired S aureus infections, and 132 (17%) had nosocomial S aureus infections. 47 (6%) had meticillin-resistant infections. 301 (40%) participants had an initial deep infection focus. Standard antibiotics were given for 29 (IQR 18-45) days; 619 (82%) participants received flucloxacillin. By week 12, 62 (17%) of participants who received rifampicin versus 71 (18%) who received placebo experienced treatment failure or disease recurrence, or died (absolute risk difference -1·4%, 95% CI -7·0 to 4·3; hazard ratio 0·96, 0·68-1·35, p=0·81). From randomisation to 12 weeks, no evidence of differences in serious (p=0·17) or grade 3-4 (p=0·36) adverse events were observed; however, 63 (17%) participants in the rifampicin group versus 39 (10%) in the placebo group had antibiotic or trial drug-modifying adverse events (p=0·004), and 24 (6%) versus six (2%) had drug interactions (p=0·0005). INTERPRETATION: Adjunctive rifampicin provided no overall benefit over standard antibiotic therapy in adults with S aureus bacteraemia.

Global urban environmental change drives adaptation in white clover

Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale

Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.

BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses

To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1–11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common in COVID-19 than controls and some (including against MYL7, UCH-L1, and GRIN3B) are more frequent with altered consciousness. Additionally, convalescent participants with neurological complications show elevated GFAP and NfL, unrelated to attenuated systemic inflammatory mediators and to autoantibody responses. Overall, neurological complications of COVID-19 are associated with evidence of neuroglial injury in both acute and late disease and these correlate with dysregulated innate and adaptive immune responses acutely
