    Queering the grammar school boy: class, sexuality and authenticity in the works of Colin MacInnes and Ray Gosling

    Get PDF
    In 1959 Colin MacInnes published the fourth in his series of social issue novels, Absolute Beginners. In it the unnamed protagonist is constructed as the iconic teenager, slick, cool, creative, with his ex-lover Crépe Suzette as the object of his art and as his Achilles heel. The novel is framed over one summer, against a backdrop of racial tension, which ultimately led the Boy towards adulthood. MacInnes’s protagonist has been dismissed as an emblem rather than a character, and MacInnes himself derided by George Melly as a perpetual teenager. However in this chapter, we will suggest that taken as a whole MacInnes’ work constructs a complex understanding of The Boy’s political possibilities intersecting with sexuality, gender, race and class. By integrating his novelistic work with his journalistic and activist writing, we will demonstrate the complexity of MacInnes’ Boy as an autonomous, queer political agent, embodied in the ultimate Boy; Ray Gosling. Gosling’s own writing becomes a lens through which to root historical understanding of teenagers and teenage cultures as sexual and racial constructs

    Purpose – The paper describes how the classic Delphi method can be adapted and structured to ensure that specific research questions are clearly addressed. Design/methodology/approach – As part of a larger mixed method project, a modified Delphi study was undertaken to explore factors influencing publication and non-publication of mental health nursing research. Findings - This paper reports brief findings from the Delphi study. However, its main focus is the methodological issues arising from the Delphi method. Implications - The paper argues that the classic Delphi method can be adapted and structured to ensure that specific research questions are able to be clearly answered. The adaptations are pragmatic in approach and in keeping with the general principles underpinning the Delphi method, while successfully addressing the problems of attrition and previous criticism of homogenous panels. Originality/value - This paper offers some practical solutions to issue arising from undertaking research using the Delphi method

    Comparison of Earthquake Source Models for the 2011 Tohoku Event Using Tsunami Simulations and Near‐Field Observations

    Selection of the earthquake source used in tsunami models of the 2011 Tohoku event affects the simulated tsunami waveform across the near field. Different earthquake sources, based on inversions of seismic waveforms, tsunami waveforms, and Global Positioning System (GPS) data, give distinguishable patterns of simulated tsunami heights in many locations in Tohoku and at near‐field Deep‐ocean Assessment and Reporting of Tsunamis (DART) buoys. We compared 10 sources proposed by different research groups using the GeoClaw code to simulate the resulting tsunami. Several simulations accurately reproduced observations at simulation sites with high grid resolution. Many earthquake sources produced results within 20% difference from the observations between 38° and 39° N, including realistic inundation on the Sendai plain, reflecting a common reliance on large initial seafloor uplift around 38° N (±0.5°), 143.25° E (±0.75°). As might be expected, DART data was better reproduced by sources created by inversion techniques that incorporated DART data in the inversion. Most of the earthquake sources tested at sites with high grid resolution were unable to reproduce the magnitude of runup north of 39° N, indicating that an additional source of tsunamigenic energy, not present in most source models, is needed to explain these observations

    Restarting a prisoner's life onto a supportive path leading to RESETtlement in the community: The RESET Study

    Executive Summary The potential of not having secure accommodation upon release from prison is a major problem for prisoners with mental health needs. This study focused on evaluating an intervention that supported prisoners upon their release from prison with the primary objective being to support them in finding accommodation release from prison service. In September, 2019 there were 83,518 prisoners detained in England and Wales (Her Majesty’s Prison and Probation Service, 2019). The period of transition from prison to the community has been acknowledged as a confusing and chaotic experience for many which is intensified by being homeless. A recent survey ascertained that 36% of people found rough sleeping had previously been in prison (CHAIN, 2018). Being homeless is viewed as a major factor in the likelihood of reoffending (Homeless Link, 2018) and not engaging with support services (health services, GP services, welfare benefits) (Williamson, 2007). It has been estimated that over 90% of prisoners have one or more psychiatric disorders (psychosis, neurosis, personality disorder, hazardous drinking and drug dependency). The period directly before and following release from prison is a highly stressful and isolating experience that exacerbates mental health problems (Theurer & Lovell, 2008; The Mental Welfare Commission for Scotland, 2017). Hopkins & Thornicroft (2014) have also reported that prisoners with mental health problems have twenty-nine times the rate of all-cause mortality during the first two weeks after release compared to the general population and are 8.3 times more likely to commit suicide in the twelve months following release from prison compared to the general population. Hancock et al (2018) has proposed that secure housing is the most important factor in ensuring a positive transition from prison to the community for people with mental health problems due to: • It is impossible to address mental health support and treatment before a person has stable accommodation • without housing they are lost to care. If someone does not have a fixed address, they are difficult to locate and connect with which makes it hard to provide support • housing helps break a cycle of returning to poor previous relationships and routines Providing support for prisoners with mental health needs upon their release has the potential to be an important factor in helping reintegrate this cohort into the community through helping to find secure accommodation, improving health and wellbeing, engaging with services, re-establishing contacts with family and friends and reducing reoffending. The Bradley Report (2009) noted if prisoners receive the support they need inside prisons, they were more likely to engage with services outside prison. The report added for the resettlement of prisoners with mental health needs into the community to be successful, it was important to ensure that the engagement that had started in prisons continued once prisoners leave the prison gate. However, the evidence for the effectiveness of existing services approaches is limited. Hopkin et al (2018) undertook a systematic review examining interventions for prisoners with diagnosed mental health conditions that targeted the transition period between prison and the community. Thirteen studies were found (with only two in the UK). The conclusions drawn were that there was some evidence that the interventions examined could improve contact between service users and mental health and other services. However, evidence that it reduced reoffending was equivocal and none on of the studies had examined whether the intervention improved access to secure accommodation. During the period of the study, the standard care package offered to prisoners upon their release was based on the government’s Transforming Rehabilitation strategy aimed to reduce reoffending and to provide a seamless transition between prison and the community by developing “Through the Gate” services (Ministry of Justice, 2013). The Through the Gate service was delivered by the newly commissioned local Community Rehabilitation Companies (CRCs) to help prisoners maintain or find accommodation; aid with finance, benefits and debt; and to support them to enter education, training and employment. It has been noted that prisoners with mental health needs present different challenges, have multiple and complex needs and require a more focused approach than the support provided by the CRCs. In addition, limitations in the amount of support and assistance offered to prisoners with mental health needs and, in particular, the lack of planning and arrangements for suitable accommodation were identified by Her Majesty’s Inspectorate of Probation reports (HMIP, 2019). To provide intensive support to those who had offended but also have identified mental health needs, Oxleas NHS Foundation Trust commissioned Clarion Housing (at the time known as Centra) and Nacro to provide a resettlement service for prisoners with mental health needs upon their release; the Supporting Prisoners upon Release Service (RESET) Intervention service. Clarion Housing worked from HMP Elmley, HMP Rochester and HMP Stamford Hill, while Nacro and Clarion Housing operated in London from HMP ISIS, HMP Belmarsh and HMP Thameside. The threshold for meeting the criteria for receiving support was that service users must have had limited community support in place, high rates of reoffending, and meet at least step 3 on the Oxleas stepped care model. The RESET service was based on the principles of the Critical Time Intervention (CTI) approach. CTI is a structured, time limited intervention developed in the USA in the 1990s to prevent recurrent homelessness in transient individuals with severe and mental illness moving from hospital care into the community. In CTI, case managers provided support for up to nine months to strengthen times with family, friends and service providers and to provide practical and emotional support during the transition in to the community. Studies had found significantly reduced number of homelessness for those users receiving CTI (Susser et al, 1997). The main elements of the RESET service were: • A short-term (12 week) support service to prisoners with an identified level of mental health need • The focus was in obtaining appropriate safe and secure accommodation, access to welfare benefits, re-engagement with health services and strengthening links with family and community support services • Referrals to the service were made through the Mental Health Inreach team at each prison • Work began before release to develop rapport with service user, to try to secure accommodation, and start to fill out necessary paperwork • On the day of release, the support co-ordinator would meet the service user at the gate • The main aim in first day is to ensure the individual has some form of housing • Any released prisoner would be escorted to all crucial appointments on the day, such as probation and local authority housing • Support was provided to ensure that the service users had all the essentials for the first few days i.e. correct medication, scripts and planned appointments • The support co-ordinator worked intensively during the first week of service users release and then gradually reduced their level of contact The overall aim of this study was to evaluate the impact of the RESET service. The specified objectives were to examine the: • Participants’ housing situation • Rate of reoffending • Number of hospital admissions • Number on maintained benefits • Number of contacts with mental health and GP services • Level of engagement with services • Number in employment or education • The service user’s views of the RESET servic

    Forensic mental health services have largely ignored examining users’ views on the nature of the service offered to them. Priebe and colleagues have developed a structured communication approach placing the service users’ perspective of their care at the heart of the discussions between service users and clinicians. This approach was used as the basis of a pilot study to evaluate a structured six-month approach designed to increase the quality of life of service users in secure settings. The specific objectives of the study were to: • Establish the feasibility of the trial design as the basis for determining the viability of a large full-scale trial • Determine the variability of the outcomes of interest • Estimate the costs of the intervention • If necessary, to refine the intervention following the study based upon the experiences of the clinicians and service users. A 36 month pilot trial was undertaken. Participants were recruited from 6 medium secure in–patient services with 55 patients in the intervention group and 57 in the control group as well as 92 nurses (47 in the intervention group and 45 in the control group). The intervention was based on the structured communication approach. Assessments took place prior to the intervention (baseline), at 6 months (post intervention) and at 12 months (follow-up). A review of the trial design indicated this approach was viable as the basis for a large full-scale trial; no refinements were needed to the intervention. The variability of the outcomes can be used start thinking about how large a full scale trial needs to be. A full trial would be able to estimate the effect of the intervention whereas this small pilot study cannot. The total cost of the intervention was £29,100 (£529 per patient) when assuming the intervention was part of the nurses normal work. Disturbed behaviour was also found to be costly since it was associated with significant use of NHS resources and police

    Study to assess the effect of a structured communication approach on quality of life in secure mental health settings (Comquol): study protocol for a pilot cluster randomized trial

    Background Forensic mental health services have largely ignored examining patients’ views on the nature of the service offered to them. A structured communication approach (DIALOG) has been developed with the aim of placing the patient’s perspective of their care at the heart of the discussions between patients and clinicians. The effectiveness of the structured communication approach in community mental health services has been demonstrated but no trial taken place in a secure psychiatric setting. This pilot study is evaluating a six-month intervention combining DIALOG with principles of Solution Focused Therapy (SFT) on quality of life in medium secure settings. Methods/design A cluster randomized controlled trial design is being employed to conduct a 36 months pilot study. Participants are recruited from six medium secure in–patient services with 48 patients in the intervention group and 48 in the control group. The intervention uses a structured communication approach. It comprises of six meetings between patient and nurse over held once a month a six month period. During each meeting patients rate their satisfaction with a range of life and treatment domains with responses displayed on a tablet. The rating is followed by a discussion on how to improve the current situation in those domains identified by the patient. Assessments take place prior to the intervention (baseline), at 6 months (post intervention) and at 12 months (follow-up). The primary outcome is self reported Quality of Life. Discussion: The study aims to a) establish the feasibility of the trial design as the basis for determining the viability of a large full-scale trial, b) determine the variability of the outcomes of interest (quality of life, levels of satisfaction, disturbance, ward climate, and engagement with services) c) estimate the costs of the intervention and d) refine the intervention following the outcome of the study based upon the experiences of the nurses and patients. The intervention allows patients to have a greater say in how they are treated and targets care on areas that patients identify as important to them. It is intended to establish systems that support meaningful patient (and carer) involvement and participation.

    Historical tsunami observability for Izu–Bonin–Mariana sources

    Get PDF
    The Izu–Bonin–Mariana Subduction System (IBM) is one of the longest subduction zones in the world with no instrumental history of shallow focus, great earthquakes (Mw \u3e 8). Over the last 50 years, researchers have speculated on the reason for the absence of large magnitude, shallow seismicity on this plate interface, exploring factors from plate age to convergence rate. We approach the question from a different point of view: what if the IBM has hosted great earthquakes and no documentable evidence was left? To address the question of observability, we model expected tsunami wave heights from nine great earthquake scenarios on the IBM at selected locations around the Pacific Basin with an emphasis on locations having the possibility for a long, written record. Many circum-Pacific locations have extensive written records of tsunami run-up with some locations in Japan noting tsunami back to 684 CE. We find that most IBM source models should theoretically be observable at historically inhabited locations in the Pacific Basin. Surprisingly, however, some IBM source models for earthquakes with magnitudes as high as Mw 8.7 produce tsunami wave heights that would be essentially unobservable at most historically populated Pacific Basin locations. These scenarios aim to provide a constraint on the upper bound for earthquake magnitudes in the IBM over at least the past 400 years

    Autonomous three-dimensional formation flight for a swarm of unmanned aerial vehicles

    This paper investigates the development of a new guidance algorithm for a formation of unmanned aerial vehicles. Using the new approach of bifurcating potential fields, it is shown that a formation of unmanned aerial vehicles can be successfully controlled such that verifiable autonomous patterns are achieved, with a simple parameter switch allowing for transitions between patterns. The key contribution that this paper presents is in the development of a new bounded bifurcating potential field that avoids saturating the vehicle actuators, which is essential for real or safety-critical applications. To demonstrate this, a guidance and control method is developed, based on a six-degreeof-freedom linearized aircraft model, showing that, in simulation, three-dimensional formation flight for a swarm of unmanned aerial vehicles can be achieved

    A pilot cluster randomised trial to assess the effect of a structured communication approach on quality of life in secure mental health settings: the Comquol study

    Background There is a lack of research in forensic settings examining therapeutic relationships. A structured communication approach, placing patients’ perspectives at the heart of discussions about their care, was used to improve patients’ quality of life in secure settings. The objectives were to: • Establish the feasibility of the trial design • Determine the variability of the outcomes of interest • Estimate the costs of the intervention • If necessary, refine the intervention Methods A pilot cluster randomised controlled trial was conducted. Data was collected from July 2012 to January 2015 from participants in 6 medium secure in–patient services in London and Southern England. 55 patients and 47 nurses were in the intervention group with 57 patients and 45 nurses in the control group. The intervention comprised 6 nurse-patient meetings over a 6 month period. Patients rated their satisfaction with a range of domains followed by discussions on improving patient identified problems. Assessments took place at baseline, 6 months, and 12 months. Participants were not blind to their allocated group. The primary outcome was self-reported quality of life collected by a researcher blind to participants’ allocation status. Results The randomisation procedures and intervention approach functioned well. The measures used were understood by the participants and gave relevant outcome information. The response rates were good with low patient withdrawal rates. The quality of life estimated treatment effect was 0.2 (95% CI: -0.4 to 0.8) at 6 months and 0.4 (95% CI: -0.3 to 1.1) indicating the likely extreme boundaries of effect in the main trial. The estimated treatment effect of the primary outcome is clinically important, and a positive effect of the intervention is not ruled out. The estimate of the ICC for the primary outcome at 6 and 12 months was 0.04 (0.00 to 0.17) and 0.05 (0.00 to 0.18). The cost of the intervention was £529 per patient. Conclusions The trial design was viable as the basis for a full-scale trial. A full trial is justified to estimate the effect of the intervention with greater certainty. The variability of the outcomes could be used to calculate numbers needed for a full-scale trial. Ratings of need for therapeutic security may be useful in any future study

    Thermal conductivity measurement of liquids in a microfluidic device

    Get PDF
    A new microfluidic-based approach to measuring liquid thermal conductivity is developed to address the requirement in many practical applications for measurements using small (microlitre) sample size and integration into a compact device. The approach also gives the possibility of high-throughput testing. A resistance heater and temperature sensor are incorporated into a glass microfluidic chip to allow transmission and detection of a planar thermal wave crossing a thin layer of the sample. The device is designed so that heat transfer is locally one-dimensional during a short initial time period. This allows the detected temperature transient to be separated into two distinct components: a short-time, purely one-dimensional part from which sample thermal conductivity can be determined and a remaining long-time part containing the effects of three-dimensionality and of the finite size of surrounding thermal reservoirs. Identification of the one-dimensional component yields a steady temperature difference from which sample thermal conductivity can be determined. Calibration is required to give correct representation of changing heater resistance, system layer thicknesses and solid material thermal conductivities with temperature. In this preliminary study, methanol/water mixtures are measured at atmospheric pressure over the temperature range 30–50°C. The results show that the device has produced a measurement accuracy of within 2.5% over the range of thermal conductivity and temperature of the tests. A relation between measurement uncertainty and the geometric and thermal properties of the system is derived and this is used to identify ways that error could be further reduced
